Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(first embodiment)

Fig. 1 to 7 show a first embodiment of the present invention. Fig. 1 to 5 are views showing a casting 19F, fig. 1 is a plan view, fig. 2 is a front view, fig. 3 is a view taken along line B-B of fig. 1, and fig. 4 is a side view (a view taken along line C-C of fig. 1).

As shown in the above figures, the casting 19F includes: four castings 100 that ultimately become articles; a connecting portion 101 (ingate) for connecting the castings 100; two integral suspension lug parts 102 connected to the connection part 101; a connecting portion 103 (runner) for connecting the two integral suspension lug portions 102; a pouring section 104 (pouring gate) connected to the connection section 103; a protrusion 105 provided at the connection portion of the connection portions 101 and 103; and four casting-accommodating lug parts 106 provided near the casting 100 of the coupling part 101.

The coupling portion 101 is a portion that constitutes a so-called runner from the pouring portion 104 to the casting 100 together with the coupling portion 103, and the vicinity of the casting 100 where the casting-receiving lug portion 106 is formed of the coupling portion 101 constitutes a so-called ingate portion.

The casting 19F is hung by a hanger hook as described later, but in this case, an integral hanging hanger part 102 is used. That is, the integral hanging lug part 102 is an engagement part for hanging the whole of the casting 19F, and the integral hanging lug part 102 is hung from the lug hook.

The projection 105 is a portion to be gripped by the robot when the casting 19F is transferred by the robot.

Fig. 5 is a diagram showing a region of a main part of the casting 19F, in which a region indicated by oblique lines is a casting 100, a region indicated by a + number is a hanger part 102 for integral suspension, and a region indicated by a mesh line is a hanger part 106 for casting accommodation.

As shown in the above figures, in the cast product 19F, when the reference line X-X and two reference lines Y1-Y1 and Y2-Y2 orthogonal to the reference line X-X are set, two cast products 100 are disposed on the reference lines Y1-Y1 and Y2-Y2, respectively, with the reference line X-X interposed therebetween.

The integral suspension hanger part 102 is a member in which two rod-shaped parts 102a and 102b are joined in a T-shape, the rod-shaped parts 102a and 102b are positioned and arranged on the reference line X-X by the two integral suspension hanger parts 102, and the connecting part 103 is formed between the rod-shaped parts 102a and 102 a.

the casting receiving lug portion 106 is a member in which rod-shaped portions 106a and 106b are joined in a T-shape, and the rod-shaped portion 106a is a part of the connecting portion 101 and constitutes the ingate.

In one of the two set of the hanger parts 106 for housing castings, the rod-like part 106a is positioned on the reference line Y1-Y1 such that the rod-like parts 106a and 106a are arranged to face each other.

Similarly, the other two casting-accommodating hanger parts 106 are disposed on the reference lines Y2 to Y2.

the rod-shaped portions 102a of the two integral suspension lug portions 102 are connected to the coupling portion 101.

Next, a casting 19F having the above-described suspension lug part 102 for integral use and the casting receiving lug part 106, and a casting facility using the respective suspension lug parts will be described.

Fig. 6 is a schematic plan view showing a casting facility 1, and the casting facility 1 includes a molding facility 2, a core setting facility 3, a cooling and conveying facility 4, a pouring facility 7, a post-treatment facility 8, and a sand treatment facility 10.

The molding device 2 molds the mold with the molding sand processed by the sand processing device 10. The core setting device 3 sets a core in the mold. The pouring device 7 produces molten metal and pours it into the mold. The cooling and conveying facility 4 conveys the mold molded in the molding facility 2 to the pouring facility 7. The cooling and conveying device 4 also conveys the mold into which the molten metal in the pouring facility 7 is poured, and cools the mold for a predetermined time. Thus, the molten metal poured into the mold is cooled and hardened, and the casting 19F having the casting-receiving lug portion 106 is provided at the portion constituting the sprue portion formed in the vicinity of the casting 100. Subsequently, the mold is released and the cast 19F is taken out, and the taken-out cast 19F is further cooled while being conveyed to the post-processing equipment 8. The post-treatment facility 8 performs post-treatments such as imprinting of the casting 19F, separation of the casting 19F from the ingate, machining, and the like, and obtains the casting 100 as a final product from the casting 19F. The sand treatment device 10 treats the molding sand used for the molding of the mold.

The cooling and conveying apparatus 4 has a mold release device 65. The post-processing equipment 8 has an imprint device 84 and a casting-and-ingate separating device 85, and after the casting 19F is imprinted by the imprint device 84, each casting 100 of the casting 19F is separated from the ingate by the casting 100-and-ingate separating device 85. After the castings 100 are separated from the ingate, each casting 100 is mounted in a receiver and transported to the machining facility 86 at another site.

Each casting 100 is machined by the machining equipment 86, such as removal of foreign matter, cutting, grinding, and polishing, at a necessary portion of each casting 100, to form a product.

The following describes a process of using each ear portion of the casting 19F in each of the above-described devices and facilities.

Fig. 7 is an explanatory diagram showing a state where the mold is released by the mold releasing device 65.

In fig. 7, reference numeral 110 denotes a mold in which a casting 19F is formed, 111 denotes a conveying path of the mold 110, 112 denotes a suspension device having a lug hook 113 provided in a direction intersecting the conveying path 111, and 114 denotes a pusher provided on the conveying path 111. Note that 115 is a table provided so as to be connected to the conveyance path 111, and one end 115a is supported so as to be rotatable, and is supported at the same height as the conveyance path 111 in a normal state, but is also supported so as to be free to rotate in the direction of arrow R1 by a drive mechanism not shown.

The molds 110 conveyed along the conveying path 111 are pushed by the pusher 114 and placed on the table 115. At this time, the lug hooks 113 of the suspending device 112 are moved to the positions shown in fig. 7 by a driving mechanism not shown, and the mold 110 is moved to the positions where the lug portions 102 for suspending the entire casting 19F in the mold 110 are hooked to the lug hooks 113 by the driving of the push rod 114.

When the support of the table 115 is released and the table is rotated in the direction of the arrow R1, the integral suspension hanger 102 is hooked on the hanger hook 113, and the mold 110 and the cast material 19F are rotated and dropped. Most of the molding sand constituting the mold 110 is separated from the casting 19F by the above-described falling action, and falls downward.

In this way, the casting 19F can be smoothly released from the mold by providing the integral suspension lug portion 102, and damage such as driving of the casting 19F during releasing can be prevented.

On the other hand, the casting 19F engraved by the engraving device 84 is separated into the castings 100 shown in fig. 1 to 5 by the casting 100 and the ingate separating device 85.

At this time, the cutting portion when each casting 100 is separated is a boundary portion 107 between the casting-accommodating lug portion 106 and the coupling portion 101 shown in fig. 5, and the casting-accommodating lug portion 106 is left in a state of being retained in each casting 100.

At this time, die data (japanese model デ ー タ) of the mold is input in advance to the cutting portion, and cutting is performed by the processing machine based on the die data.

Each of the castings 100 thus obtained is mounted in a housing and transported to a machining facility 86 at another site.

Fig. 8 and 9 are views showing a state in which the casting 100 is mounted in the housing, and reference numeral 120 in the above-mentioned figures denotes the housing. The housing 120 is a member having a C-shaped cross-sectional shape and extending in one direction, and is provided with a main wall portion 120a, side wall portions 120b, and lower wall portions 120C, and the plurality of castings 100 are suspended from the housing.

Since the casting 100 has the casting-receiving hanger part 106 in a part thereof, the casting 100 can be suspended in a fixed posture from the housing 120 by inserting the rod-shaped part 106b of the casting-receiving hanger part 106 into the housing 120 and engaging the rod-shaped part 106b with the upper surfaces of the lower wall parts 120c and 120 c. Further, by adopting a structure in which the housing 120 is extended long in the fixing direction, a large number of castings 100 can be mounted on the housing.

When the casting 100 is mounted to the housing 120, the rod-shaped portion 106a of the casting housing lug part 106 is gripped by a robot and mounted to the housing 120.

The casting 100 mounted in the container as described above is transported to the machining facility 86 at another site, and machining, finishing, and the like for separating the casting-housing hanger part 106 from the casting 100 are performed in the machining facility 86 by an NC lathe or the like.

At this time, the casting 100 is supplied to the machine tool by the robot gripping the rod-shaped portion 106a of the casting housing lug part 106 from the housing 120, but since the casting 100 is suspended from the housing 120 in a fixed posture, the robot can easily and accurately grasp the casting, and it is possible to prevent troubles such as dropping of the casting 100 due to a grasping failure.

As described above, by simply hanging the casting having the casting-housing hanging lug portion 106 on the housing 120, the casting 100 can be mounted on the housing 120 in the same posture every time regardless of the shape and size of the casting 100.

In addition, when the robot is automated to grasp the casting 100 in the subsequent process, the casting 100 mounted in the storage body 120 is also stored in a fixed posture, and therefore, there is an advantage that it is not necessary for the operator to teach the robot in a high degree.

Further, since the robot can have a pick-up success rate of the casting 100 of approximately 100%, the pick-up process can be made unmanned.

Further, even if the robot is not an expensive robot having a deep learning function, since the casting 100 can be reliably grasped by only an inexpensive robot having a function of repeating a substantially fixed operation every time, the cost of implementing the invention can be kept low.

Further, since the castings are sequentially mounted on the housing, traceability can be secured even without an identification element such as an imprint of the product.

Further, since the containers (trays) are not stacked in a messy manner, damage such as driving of products is not caused.

(second embodiment)

Fig. 10 to 14 are views showing a second embodiment of the present invention.

The present embodiment differs from the first embodiment described above in the shape of the hanger part for housing a casting provided in the casting 100.

In the present embodiment, the casting receiving lug part 106A is a protruding part that protrudes from the casting 100 by a width dimension t1 corresponding to the length dimension of the rod-like part 106b of the casting receiving lug part 106 of the first embodiment, as shown in fig. 10, and the protruding part is directly joined to the coupling part 102 a.

In the above-described protruding portion, one side surface 130a and the opposite side surface 130b are locking surfaces inclined in the direction of protruding and away from each other.

in the present embodiment, as shown in fig. 14, the housing 120A for suspending the casting 100 has inclined surfaces corresponding to the side surfaces 130A, 130b of the casting-housing lug part 106A so that the side surfaces 130A, 130b can be engaged with the inner surfaces of the lower wall parts 120c, 120 c.

in the present embodiment, as shown in fig. 14, the casting 100 is configured such that the casting housing lug portion 106A is inserted into the housing 120A, and the side surfaces 130A and 130b as the engagement surfaces are engaged with and hung from the lower wall portions 120c and 120 c.

According to the structure of the present embodiment, the joint area between the casting 100 and the casting-accommodating hanger part 106A can be enlarged, and there is an advantage that the casting 100 can be hung without difficulty even when the weight of the casting is large.

In the present embodiment, the portions where the castings 100 are separated are, as shown in fig. 10, the rod-shaped portions 102a of the coupling portions 103 and the integral suspension lug parts 105, and the boundary portions 131 between the casting-accommodating lug parts 106A.

The configuration of the hanger part for housing a casting and the housing body corresponding to the hanger part are exemplified by the first embodiment and the second embodiment, but the configuration is not limited to the above embodiments, and various shapes are possible as long as the casting can be housed in a fixed posture.

In the above two embodiments, the casting 100 is housed in the housing bodies 120 and 120A so as to be suspended by the casting housing hanging lugs 106 and 106A, but the present invention is not limited to this. The receivers 120, 120A are members having a C-shaped cross-sectional shape and extending in one direction, but the receivers 120, 120A may be positioned such that the axis of the extending direction thereof is perpendicular to the ground surface, and may be configured to receive the castings 100 by locking the castings 100 in the receivers 120, 120A by the casting receiving lugs 106, 106A, thereby stacking the castings 100.

In the first and second embodiments, the case where the casting 19F includes a plurality of castings 100 has been described, but the number of castings 100 may be one in the present invention, and the present invention is applicable to a casting provided with one or more castings.
