Technical Field

The present invention relates to a rod arraying device for arraying rods represented by temporary insertion rods that penetrate through stacked bodies of heat dissipating fins before inserting refrigerant tubes into the stacked bodies of heat dissipating fins.

Background

A heat exchanger for an air conditioner or the like is formed by inserting a refrigerant tube for flowing a refrigerant into a stacked body of fins for heat dissipation. After stacking a plurality of heat radiating fins formed by a press die apparatus in a stacking apparatus in which stacking pins are erected, a stacked body of the heat radiating fins is taken out from the stacking apparatus, a temporary insertion rod is inserted in place of the stacking pins, and then a refrigerant tube is inserted.

As described above, the temporary insertion rods need to be aligned in advance in a state where the tip end portions thereof are accurately positioned, as in the case of the stacking pins in the stacking apparatus. As a mechanism for arranging the stacking pins, a content disclosed in, for example, patent document 1 (japanese patent laid-open No. 2004-330262) is proposed by the applicant, but no direct prior art document concerning an arranging device for temporarily inserting the rods is found.

Further, the present invention may be a bar arraying device including: a guide unit in which a plurality of guide plates, each having a through hole through which a rod can be inserted, are arranged in a stacked manner in a plate thickness direction so that planar view positions of the through holes are aligned, and the guide plates facing each other are slidably moved relative to the planar view positions so that the planar view positions of the through holes are shifted; a 1 st drive unit that slides the guide plate relative to a top-view position; a bottom plate provided at a lower position of the guide portion; a 2 nd driving part which lifts and lowers the base plate relative to the guide part; and an operation control unit that controls operations of the 1 st drive unit and the 2 nd drive unit, wherein after the rod body is inserted into the through hole of the guide unit, the operation control unit operates the 1 st drive unit to move the guide plate while maintaining a state in which a part of a plan view area of the through hole of the guide plate is overlapped with a part of a plan view area of the through hole, the part being opposed to each other, and the operation control unit operates the 2 nd drive unit to perform each of the following steps: raising the upper surface height position of the bottom plate to a predetermined height position in contact with the lower end portion of the rod suspended and held by the guide portion; a step of lowering the bottom plate while maintaining a state in which a lower end portion of the rod is in contact with an upper surface of the bottom plate until the rod suspended and held by the guide portion is suspended and held in a direction orthogonal to the guide portion; and a step of raising the bottom plate until the upper end of the rod protrudes from the upper surface of the guide portion.

Further, the present invention may be a bar arraying device including: a guide unit in which a plurality of guide plates having through holes through which the rods can be inserted are arranged in a stacked manner in a plate thickness direction so that the planar positions of the through holes are aligned, and the guide plates facing each other can be slidably moved relative to the planar position of the through holes so that the planar position of the through holes is shifted; a 1 st drive unit that slides the guide plate relative to a top-view position; a bottom plate provided at a lower position of the guide portion; a 2 nd driving part which lifts and lowers the base plate relative to the guide part; and an operation control unit that controls operations of the 1 st drive unit and the 2 nd drive unit, wherein the operation control unit raises a height position of an upper surface of the bottom plate to a predetermined height position that can come into contact with a lower end portion of the rod suspended and held by the guide unit, and thereafter, after the rod is inserted into the through hole of the guide unit, the operation control unit operates the 1 st drive unit to move the guide plate while maintaining a partially overlapped state of planar view regions of the through hole in the guide plate that face each other, and the operation control unit operates the 2 nd drive unit to execute the following steps: a step of lowering the bottom plate while maintaining a state in which a lower end portion of the rod is in contact with an upper surface of the bottom plate until the rod suspended and held by the guide portion is suspended and held in a direction orthogonal to the guide portion; and a step of raising the bottom plate until the upper end of the rod protrudes from the upper surface of the guide portion.

This makes it possible to reliably align rod bodies, such as temporary insertion rods, inserted into the stacked body of heat dissipation fins. In addition, since the arranged temporary insertion rods can be delivered to the temporary insertion rod insertion mechanism by the root portions, the temporary insertion rod insertion mechanism can directly insert the delivered temporary insertion rods into the stacked body of the heat dissipation fins.

Preferably, the diameter of the small-diameter hole is equal to the outer diameter of the rod.

This makes it possible to position the temporarily inserted rod with high accuracy.

Preferably, the guide part includes at least one through-hole guide plate in a tumbler shape.

This reduces the manufacturing cost of the guide portion while reducing the alignment function of aligning the temporary insertion rods by the guide portion.

In the step of lowering the bottom plate while maintaining the state in which the lower end portion of the rod is in contact with the upper surface of the bottom plate until the rod suspended and held by the guide portion is suspended and held in the orthogonal direction to the guide portion, the operation control portion preferably operates the 2 nd driving portion so that the bottom plate is lowered at a speed at which the rod inserted into the guide portion in a state inclined with respect to the guide portion changes by its own weight to a speed equal to or lower than a partial speed in the vertical direction in a state in which the rod is suspended and held in the orthogonal direction to the guide portion.

Thus, when the temporary insertion rod inserted into the guide portion in a non-vertical state is changed in posture in the vertical direction, the temporary insertion rod can be prevented from oscillating in a pendulum-like manner, and the posture can be changed in a short time so that the suspended state of the temporary insertion rod with respect to the guide portion is in a direction perpendicular to the guide portion.

Preferably, the operation control unit operates the 2 nd driving unit to perform a step of separating the bottom plate from the rod between a step of lowering the bottom plate while maintaining a state in which a lower end portion of the rod abuts on an upper surface of the bottom plate and a step of raising the bottom plate until an upper end portion of the rod protrudes from an upper surface of the guide portion.

Thus, even when the lengths of the temporary insertion rods have some variations, the suspended state of the temporary insertion rods can be changed in posture so that all the temporary insertion rods can be reliably suspended and held in the direction orthogonal to the guide portion.

Preferably, the upper surface of the bottom plate is subjected to an anti-slip process of the rod body.

Thus, when the bottom plate is lowered in a direction away from the guide portion, the lower end portion of the rod body can be reliably maintained in contact with the upper surface of the bottom plate. That is, when the posture of the stick is changed in the vertical direction, the stick does not vibrate in a pendulum shape, and the alignment of the stick can be completed in a short time.

ADVANTAGEOUS EFFECTS OF INVENTION

With the configuration of the stick body arraying device according to the present invention, the posture of the temporary insertion stick can be changed in a short time, the temporary insertion stick can be suspended and held in the orthogonal direction with respect to the guide portion, and the temporary insertion stick 90 can be aligned with a predetermined plan view position. Further, the temporary insertion rod after alignment and position alignment can be delivered to the temporary insertion rod insertion mechanism by the root portion, and therefore, the temporary insertion rod insertion mechanism can directly insert the delivered temporary insertion rod into the stacked body of the heat radiation fins, and a heat exchanger with high assembly accuracy can be manufactured in a short time.

Detailed Description

The following describes an embodiment of the rod arraying device 100 of the present invention, which uses the temporary insertion rod 90 inserted into the stacked body of the heat radiation fins as a rod.

(embodiment 1)

As shown in fig. 1 and 2, the temporary inserted rod aligning device 100 of the present embodiment includes a guide part 30 in which a 2 nd guide plate 20 is stacked on an upper surface and a lower surface of a 1 st guide plate 10, a 1 st driving part 40 for reciprocating the 1 st guide plate 10 in a horizontal direction, a base plate 50 provided at a position below the guide part 30, a 2 nd driving part 60 for moving up and down the base plate 50, and an operation control part 70. The guide unit 30 is integrally attached to the main body frame 80 together with the 1 st driving unit 40, and the base plate 50 is integrally attached to the main body frame 80 together with the 2 nd driving unit 60.

As shown in fig. 2 and 3, the 1 st guide plate 10 is formed with a large diameter hole 12 having a size through which the temporary insertion rod 90 can be inserted, and a small diameter hole 14 having a diameter smaller than the large diameter hole 12 and through which the temporary insertion rod 90 can be inserted. Here, the diameter of the small-diameter hole 14 is formed to be slightly larger than the outer diameter of the temporary insertion rod 90. The large-diameter hole 12 and the small-diameter hole 14 are formed in a state of partially overlapping each other in a plan view region, and are formed as a tumbler-shaped through-hole 16 as a whole. That is, the 1 st guide plate 10 of the present embodiment corresponds to the tumbler-shaped through-hole guide plate described in the claims. The plurality of tumbler-shaped through holes 16 are arranged in the 1 st guide plate 10 in a staggered manner at regular intervals. Further, a 1 st opening 18 is formed in a central portion of the 1 st guide plate 10 in a plan view.

A plurality of through holes 22 having a diameter greater than or equal to the diameter of the large-diameter hole 12 formed in the 1 st guide plate 10 are formed in the 2 nd guide plate 20 so as to be staggered at regular intervals. That is, the 2 nd guide plate 20 of the present embodiment corresponds to the guide plate described in the claims. Further, a 2 nd opening 24 is formed in a central portion of the 2 nd guide plate 20 in a plan view. The 2 nd guide plate 20 is stacked on the upper and lower surfaces of the 1 st guide plate 10 in a state where the plan view position of the large-diameter hole 12 is matched with the plan view position of the through hole 22 and the plan view position of the 1 st opening 18 is matched with the plan view position of the 2 nd opening 24.

In the guide portions 30 in which the 2 nd guide plate 20 is disposed on the upper surface and the lower surface of the 1 st guide plate 10, the 1 st driving portion 40 is disposed on a penetrating portion from the upper surface to the lower surface formed by the 1 st opening portion 18 and the 2 nd opening portion 24. The 1 st drive unit 40 is attached to the 2 nd guide plate 20, and the 1 st guide plate 10 is connected to an output shaft 42 of the 1 st drive unit 40. When the 1 st driving part 40 is driven, the protruding amount of the output shaft 42 changes, and the 1 st guide plate 10 moves in the horizontal direction (the coupling direction between the large diameter hole 12 and the small diameter hole 14) between the 2 nd guide plate 20 on the upper surface and the 2 nd guide plate 20 on the lower surface. In this way, the extension operation and the contraction operation of the output shaft 42 of the 1 st driving unit 40 can reciprocate the plan view position of the small-diameter hole 14 between the initial position and the predetermined position in the plan view region of the through hole 22.

In addition, a temporary insertion rod insertion hole 32 through which the temporary insertion rod 90 is inserted from the upper surface to the lower surface of the guide portion 30 is formed in the guide portion 30 by the large diameter hole 12 and the through hole 22. The guide part 30 formed in this way is attached to the main body frame 80 at the longitudinal side end part of the 2 nd guide plate 20 (the end part parallel to the reciprocating direction of the 1 st guide plate 10).

A bottom plate 50 is disposed below the guide portion 30, and a nonslip piece 52 is attached to the top surface (surface on the side where the guide portion 30 is located) of the bottom plate 50. An output shaft 62 of the 2 nd drive unit 60 is connected to the base plate 50, and the 2 nd drive unit 60 is operated to change the amount of projection of the output shaft 62, whereby the base plate 50 can be raised and lowered from an initial position (basic height position) with respect to the guide unit 30. The 2 nd driving part 60 is mounted on the main body frame 80. The 1 st drive unit 40 and the 2 nd drive unit 60 described above can be exemplified by a cylinder, and the operation of each of the 1 st drive unit 40 and the 2 nd drive unit 60 is controlled by an operation control program stored in a storage device of a personal computer, not shown, and an operation control unit 70 represented by a CPU.

In the present embodiment, the operation control unit 70 and the main body frame 80 are independent from each other, and the 1 st drive unit 40 and the 2 nd drive unit 60 are electrically connected to the operation control unit 70 via the wire harness WH, but the operation control unit 70 may be attached to the main body frame 80.

Next, a method of arranging the temporary insertion rods 90 in a state of being suspended and held in a direction orthogonal to the guide section 30 by using the temporary insertion rod arranging apparatus 100 will be described. An operator not shown inserts the temporary insertion rod 90 through the upper surface side of the temporary insertion rod insertion hole 32 formed in the guide portion 30. In the temporary insertion rod 90, the upper end portion (root portion) is formed as the flange portion 92, and the required range of the lower end portion 94 (tip portion) can also be formed as the tip tapered portion. The main portion of the temporary insertion rod 90 other than the required ranges of the flange portion 92 and the lower end portion 94 is formed to the same diameter size.

The diameter of the temporary insertion rod insertion hole 32 is formed to be larger than the outer diameter of the main portion of the temporary insertion rod 90 and smaller than the flange portion 92, so that the temporary insertion rod 90 can be inserted through all the temporary insertion rod insertion holes 32 in a short time. The flange portion 92 of the temporary insertion rod 90 that penetrates the temporary insertion rod insertion hole 32 serves as a stopper, and therefore the temporary insertion rod 90 does not fall off from the guide portion 30. Fig. 4, 5, and 6 show a front view, a sectional view, and a main part sectional view of the guide part 30 of the temporary insertion rod aligning device 100 in a state where the temporary insertion rod 90 is inserted.

As described above, since the diameter dimension of the temporary insertion rod through hole 32 is formed to be larger than the outer diameter dimension of the main portion of the temporary insertion rod 90, the temporary insertion rod 90 is suspended in a state of being inclined with respect to the guide portion 30. When the operator operates an operation button, not shown, as shown in fig. 7, the operation controller 70 operates the 1 st driving unit 40 to move the 1 st guide plate 10 horizontally between the two 2 nd guide plates 20 so that the small-diameter hole 14 enters the plan view area of the through hole 22. Since the small diameter hole 14 is formed to have a size slightly larger than the outer diameter of the main portion of the temporary insertion rod 90, the temporary insertion rod 90 is pushed out by the inner periphery of the small diameter hole 14 when the small diameter hole 14 moves to the position of the large diameter hole 12 (through hole 22) in a plan view. Thereby, the temporary insertion rod 90 moves in the horizontal direction together with the 1 st guide plate 10. Further, the diameter of the small-diameter hole 14 can be formed to have the same size as the outer diameter of the main portion of the temporary insertion rod 90.

When the outer peripheral surface of the temporarily inserted rod 90 pushed out by the small-diameter hole 14 of the 1 st guide plate 10 reaches a position abutting against the inner peripheral surface of the through-hole 22 (the plan view position of the small-diameter hole 14 is a predetermined position in the plan view region of the through-hole 22), the operation control section 70 temporarily stops the operation of the 1 st driving section 40. Thus, the temporary insertion rod 90 is restrained from moving in the horizontal direction at the target planar view position in the temporary insertion rod insertion hole 32, but the temporary insertion rod 90 suspended in a non-orthogonal direction (a direction inclined with respect to the guide portion 30) with respect to the guide portion 30 remains.

In order to cancel such a tilted suspended state of the temporarily inserted rods 90, the operation control unit 70 temporarily stops the operation of the 1 st driving unit 40, and thereafter, activates the 2 nd driving unit 60 to raise the bottom plate 50 to a position where it abuts on the lower end portions 94 of all the temporarily inserted rods 90. Specifically, the bottom plate 50 is raised to the following positions: the height position of the lower end 94 of the temporary insertion rod 90 suspended and held in the orthogonal direction with respect to the guide portion 30 is a predetermined height position on the side where the guide portion 30 is located. When the bottom plate 50 reaches the predetermined height position (1 st height position), as shown in fig. 8, the anti-slip piece 52 of the bottom plate 50 comes into contact with the lower end 94 of the temporary insertion rod 90. Next, as shown in fig. 9, the motion controller 70 operates the 2 nd driving unit 60 to move the bottom plate 50 away from the guide unit 30 (downward in the temporary insertion rod arraying device) while maintaining the contact state of the nonslip piece 52 with the lower end 94 of the temporary insertion rod 90.

At this time, the lowering speed of the base plate 50 by the 2 nd drive unit 60 is preferably equal to or lower than the partial speed in the vertical direction of the moving speed when the temporary insertion rod 90 moves in a pendulum shape by its own weight in the circular arc arrow direction in the lateral direction of fig. 9 with the restrained portion of the guide portion 30 as a vertex (the temporary insertion rod 90 is suspended and held in the orthogonal direction with respect to the guide portion 30 as indicated by the solid line) when the supported state in which the temporary insertion rod 90 in the state indicated by the broken line in fig. 9 is released from the base plate 50. At this time, as shown in fig. 10, the operation control unit 70 operates the 2 nd driving unit 60 at the above-described lowering speed until the upper surface height position of the bottom plate 50 becomes the height position (the 2 nd height position) of the lower end 94 of the temporary insertion rod 90 suspended and held in the direction orthogonal to the guide unit 30.

When the upper surface height position of the bottom plate 50 becomes the 2 nd height position, the temporary insertion rod 90 can be suspended in the orthogonal direction (vertical direction) with respect to the guide portion 30. Subsequently, the operation controller 70 further operates the 2 nd driver 60 to move the bottom plate 50 to a height position (3 rd height position: position lowered to the maximum) at which the bottom plate 50 is away from the lower end 94 of the temporary insertion rod 90, as shown in fig. 11. In this way, friction between the lower end 94 of the temporary insertion rod 90 and the bottom plate 50 can be released, and the temporary insertion rod 90 can be suspended and held in the orthogonal direction with respect to the guide portion 30 as shown in fig. 12.

Next, as shown in fig. 13, the operation control portion 70 again raises the bottom plate 50 to the side where the guide portion 30 is located, brings the anti-slip piece 52 on the upper surface of the bottom plate 50 into contact with the lower end 94 of the temporary insertion rod 90, and causes the flange portion 92, which is the root portion of the temporary insertion rod 90, to protrude from the upper surface of the guide portion 30 by a predetermined height. By thus bringing the bottom plate 50 once away from the lower end 94 of the temporary insertion rod 90 into contact with the lower end 94 again and moving up toward the guide portion 30, the flange portion 92 can be projected from the upper surface of the guide portion 30 while maintaining a suspended state in the direction orthogonal to the guide portion 30.

By positioning the position in plan view in this manner and projecting the flange portion 92 of the temporary insertion rod 90 suspended and held in the orthogonal direction (vertical direction) with respect to the guide portion 30 from the upper surface of the guide portion 30, the manipulator serving as a temporary insertion rod insertion mechanism (not shown) can reliably receive the temporary insertion rod 90. The temporary insertion rod 90 is aligned with the position of the through hole of the stacked heat dissipation fin, not shown, and the posture thereof is adjusted to be parallel to the stacking direction of the through hole, and a robot receiving such a temporary insertion rod 90 can easily and reliably insert the temporary insertion rod 90 into the through hole of the stacked heat dissipation fin.

(embodiment 2)

In the present embodiment, the same reference numerals as those used in embodiment 1 are used for the common components with embodiment 1, and a detailed description thereof is omitted here. As shown in fig. 14 and 15, in the temporary insertion rod arraying device 200 of the present embodiment, the guide portion 230, the 1 st driving portion 40, the bottom plate 50, the 2 nd driving portion 60, and the operation control portion 70 are attached to the main body frame 80. The guide part 230 of the present embodiment is characterized by being formed by stacking two sheets of the 2 nd guide plate 20 of the 1 st embodiment.

The through hole 22 provided in the 2 nd guide plate 20 (corresponding to the guide plate described in the claims) of the present embodiment is formed in a circular shape having a diameter dimension larger than the outer diameter dimension of the main portion of the temporary insertion rod 90 and smaller than the outer diameter dimension (width dimension) of the flange portion 92. The guide part 230 of the present embodiment is configured such that two pieces of the 2 nd guide plate 20 are stacked in the plate thickness direction so that the planar positions of the through holes 22 are aligned (matched), and the relative planar positions of the two pieces can be slid. As in the case of embodiment 1, the power for relatively moving the 2 nd guide plate 20 within the contact surface is obtained by the 1 st driving unit 40. The output shaft 42 of the 1 st drive unit 40 is coupled to at least one 2 nd guide plate 20.

Fig. 16 is a front view showing a state in which an operator inserts the temporary insertion rod 90 through the through-hole 22 (corresponding to the temporary insertion rod insertion hole 32 of embodiment 1) of the guide portion 230 of the temporary insertion rod arraying device 200 according to the present embodiment. Fig. 17 is a main part sectional view showing a state where the temporary insertion rod 90 is inserted through the through hole 22 of the guide part 230. When the temporary insertion rod 90 is inserted through the through hole 22 of the guide portion 230, the flange portion 92 serves as a stopper, and the temporary insertion rod 90 is suspended and held by the guide portion 230. In this case, as in embodiment 1, the position of the temporary insertion rod 90 in the plan view with respect to the guide part 230 is roughly aligned, but the position in the plan view is not precisely positioned. Therefore, the operation of the 1 st driving unit 40 is controlled by the operation control unit 70, so that the process of accurately positioning the planar view position of the temporary insertion rod 90 with respect to the guide unit 230 is performed.

In the present embodiment, the operation control unit 70 operates the 1 st driving unit 40 to slidably move one or both of the 2 nd guide plates 20 in the contact surface between the 2 nd guide plates 20. As shown in fig. 17, the output shaft 42 of the 1 st driving unit 40 of the present embodiment slides the lower 2 nd guide plate 20. The operation controller 70 causes the lower 2 nd guide plate 20 to slide by the 1 st driving unit 40 until the temporary insertion rod 90 is held between the inner peripheral edge of the through hole 22 of the upper 2 nd guide plate 20 and the inner peripheral edge of the through hole 22 of the lower 2 nd guide plate 20.

The 1 st driving unit 40 may be provided with an output signal detecting unit, not shown, and a protruding amount detecting unit for the output shaft 42, and the output signal detected by the output signal detecting unit and the protruding amount signal detected by the protruding amount detecting unit for the output shaft 42 may be transmitted to the operation control unit 70 in advance. Thus, even when the output signal of a predetermined value or more is detected from the 1 st driving unit 40 but the amount of projection of the output shaft 42 is not increased, the operation control unit 70 can determine that the temporary insertion rod 90 is sandwiched between the inner peripheral edges of the through holes 22 of the two second guide plates 20. This makes it possible to control the operation of the 1 st driving unit 40 so as to prevent the guide unit 230, the 1 st driving unit 40, and the temporary insertion rod 90 from being damaged.

Fig. 18 shows a main part cross-sectional view in a state where the outer peripheral surface of the temporary insertion rod 90 is sandwiched between the inner peripheral edges of the through holes 22 of the two second guide plates 20 and the temporary insertion rod 90 is positioned with respect to the hanging plan position of the guide part 230. Fig. 19 is a front view of the temporary insertion rod arraying device 200 in this state. The outer peripheral surface of the temporary insertion rod 90 is sandwiched between the inner peripheral edges of the through holes 22 of the two second guide plates 20, whereby the position of the temporary insertion rod 90 in the plan view with respect to the guide part 230 is accurately positioned. However, a part of the temporary insertion rod 90 is held in a non-orthogonal direction with respect to the guide part 230.

Therefore, the operation control unit 70 controls the operation of the 2 nd driving unit 60 to move the bottom plate 50 up and down, as in the case of embodiment 1, so that all the temporary insertion rods 90 are suspended and held in the orthogonal direction with respect to the guide unit 230. The operation control of the 2 nd driving unit 60 (the raising and lowering operation of the base plate 50) by the operation control unit 70 of the present embodiment can be performed in the same manner as in embodiment 1 (see fig. 8 to 11), and therefore, a detailed description thereof is omitted. The operation control unit 70 controls the operation of the 2 nd driving unit 60 to suspend and hold all the temporary insertion rods 90 in the direction perpendicular to the guide unit 230, and then, as shown in fig. 20, raises the base plate 50 by the 2 nd driving unit 60, thereby bringing the flange 92 into a state of protruding from the upper surface of the guide unit 230 by a predetermined height. Thus, the manipulator, which is a temporary insertion rod insertion mechanism not shown, can reliably receive the temporary insertion rod 90.

The temporary insertion rod 90 received by the robot is aligned with the position of the through hole of the stacked heat dissipation fins, not shown, and its posture is adjusted to be parallel to the stacking direction of the through hole, so that the temporary insertion rod 90 can be easily and reliably inserted into the through hole of the stacked heat dissipation fins.

The rod arraying device of the present invention has been described above based on the temporary insertion rod arraying device 200 of the embodiment in which the temporary insertion rod 90 is used as the rod, but the rod arraying device of the present invention is not limited to the above embodiment.

For example, in the temporary inserted rod aligning device 100 according to embodiment 1, a description has been given of a mode in which the guide sections 30 of the 2 nd guide plate 20 having a total of 3 pieces of structure are stacked on the upper surface and the lower surface of the 1 st guide plate 10, but the guide sections 230 having a two-piece structure may be provided as in embodiment 2. In this case, one guide plate is used for each of the 1 st guide plate 10 and the 2 nd guide plate 20. The guide part 30 may have a structure of 4 or more pieces including the 1 st guide plate 10 and the 2 nd guide plate 20, and the arrangement position of the 1 st guide plate 10 and the 2 nd guide plate 20 in the stacking direction is not particularly limited. Similarly, the guide part 230 of embodiment 2 can also be formed by stacking 3 or more 2 nd guide plates 20 in the plate thickness direction.

As described above, the guide unit 30, 230 of the present invention may be configured as follows: a plurality of guide plates (the 1 st guide plate 10 and/or the 2 nd guide plate 20) are stacked in the plate thickness direction in a state where the through-holes (the large-diameter hole 12 and the through-hole 22) formed in the guide plates (the 1 st guide plate 10 and/or the 2 nd guide plate 20) are aligned in plan view.

In embodiment 1, the mode in which the relative position between the 1 st guide plate 10 and the 2 nd guide plate 20 is changed by sliding the 1 st guide plate 10 of the guide part 30 in the horizontal plane has been described, but the mode is not limited to this mode. The following can also be adopted: the relative position between the 1 st guide plate 10 and the 2 nd guide plate 20 constituting the guide part 30 is changed by moving at least either one of the 1 st guide plate 10 and the 2 nd guide plate 20 constituting the guide part 30 in the horizontal direction. When the plurality of guide plates are slid and moved in the horizontal direction, the movement directions of the vertically adjacent guide plates are preferably opposite (opposite directions).

In both embodiment 1 and embodiment 2, the temporary insertion rod 90 is inserted into the temporary insertion rod insertion hole 32 of the guide part 30, 230, and after the operation control part 70 performs the positioning process of the position in the plan view by the 1 st guide plate 10, the bottom plate 50 is raised to abut against the lower end 94 of the temporary insertion rod 90. The operation control unit 70 may control the operation of the 2 nd driving unit 60 so that the initial height position of the upper surface of the base plate 50 (before the temporary insertion rod 90 is inserted into the guide portions 30 and 230) is a predetermined height position on the side where the guide portions 30 and 230 are located with respect to the height position of the lower end 94 of the temporary insertion rod 90 suspended and held in the orthogonal direction with respect to the guide portions 30 and 230.

Further, the mounting position of the 2 nd driving part 60 to the main body frame 80 can be adjusted so that the initial height position of the upper surface of the base plate 50 becomes the height position described above.

In both embodiments 1 and 2, the 1 st driving unit 40 is disposed in a penetrating portion from the upper surface of the guide portion 30, 230 to the lower surface of the guide portion 30, 230, which is formed by the 1 st opening 18 and the 2 nd opening 24, but the 1 st driving unit 40 may be disposed on either the upper surface or the lower surface of the guide portion 30, 230. In this case, an output shaft through hole, not shown, through which the output shaft 42 of the 1 st driving part 40 is inserted may be formed in the 2 nd guide plate 20 on the side where the 1 st driving part 40 is disposed, as a long hole that is long in the reciprocating direction of the 1 st guide plate 10. The 1 st driving unit 40 may be disposed outside the plan view area of the guide units 30 and 230.

When the 1 st driving unit 40 is disposed outside the plan view area of the guide units 30 and 230, as shown in fig. 2 to 3, for example, the end portion of the guide plate that slides in the sliding direction (here, the 1 st guide plate 10) may be stacked in a state of protruding from the end portion of the other guide plate (here, the 2 nd guide plate 20) in the sliding direction, or the guide plate that slides in the sliding direction (here, the 1 st guide plate 10) may be formed to be long in the sliding direction. Accordingly, the output shaft 42 of the 1 st driving part 40 and the 1 st guide plate 10 or the 2 nd guide plate 20 that slides can be easily coupled.

In embodiment 2, the through holes 22 formed in the two 2 nd guide plates 20 are formed in the same shape having the same diameter and size, but the invention is not limited to this embodiment. The 2 nd guide plate 20 formed with the through-holes 22 different in at least one of size and shape may also be used.

Further, the anti-slip sheet 52 is attached as an anti-slip process to the upper surface of the bottom plate 50 in the present embodiment, but the present invention is not limited to this embodiment. The upper surface of the bottom plate 50 may be subjected to a rough surface treatment, typically, to provide a slip-proof treatment.

Further, the embodiment and various modifications described above may be combined with each other as appropriate.
