The arrangement of the guide vertical plates 54 ensures that the posture of the round rods cannot be changed when the material taking toothed plate 31 jacks up the round rods and puts the round rods into the tooth-shaped grooves of the support vertical plates 20 and the round rods are jacked up by the arrangement plate 41 to displace, so that the round rods are neatly arranged. In order to ensure the strength of the upright guiding plate 54, the upright guiding plate 54 has a certain width, but the wider upright guiding plate 54 occupies the arrangement space of the round bar, so the upright guiding plate 54 is disposed to be inclined toward the upright supporting plate 20 in this embodiment.

Referring to fig. 3, a material extracting mechanism 30 according to the present invention is schematically shown. In this embodiment, the first lifting and translating assembly 32 includes a lifting cylinder 33, a translating and mounting plate 34, a material pulling plate 35 and a translating and mounting cylinder 36, the lifting cylinder 33 is fixedly mounted on the supporting vertical plate 20, a push rod of the lifting cylinder 33 is connected to the translating and mounting plate 34, the translating cylinder 36 is mounted at one end of the translating and mounting plate 34, the push rod of the translating cylinder 36 is connected to the material pulling plate 35, the material pulling plate 35 is connected to the translating and mounting plate 34 through a slide rail and a slide block, and the material taking toothed plate 31 is fixedly connected to the material pulling plate 35. During operation, the translation cylinder 36 pushes out the material pulling plate 35 to the material taking position, and the material pulling plate 35 moves along the sliding rail, so that the material taking toothed plate 31 moves to the lower side of the round rod. Then the lifting cylinder 33 jacks up the translation mounting plate 34, the material taking toothed plate 31 on the translation mounting plate 34 is jacked up, and the round rod is ejected out of the support plate. Then translation cylinder 36 drives the flitch 35 and withdraws along the slide rail, and lift cylinder 33 descends and resets, gets material pinion rack 31 and descends to being less than the height that supports riser 20, gets the round bar on the material pinion rack 31 and is supported by supporting riser 20, realizes taking out the round bar from the feed position.

Referring to fig. 1, since the material taking mechanism 30 and the aligning mechanism 40 are both matched with the second tooth-shaped groove on the supporting plate, in order to prevent the interference between the material taking mechanism 30 and the aligning mechanism 40, the material taking mechanism 30 and the aligning mechanism 40 are respectively disposed on two sides of the supporting vertical plate 20, in this embodiment, the material taking mechanism 30 is mounted on the inner side of the supporting vertical plate 20, and the aligning mechanism 40 is mounted on the outer side of the supporting vertical plate 20. Further, in this embodiment, the material taking toothed plate 31 and the arrangement plate 41 both function to jack up the round bar and then displace one tooth-shaped groove, so that the second lifting and translating assembly 42 has the same structure as the first lifting and translating assembly 32. The matching structure of the air cylinder and the slide rail is simple and low in cost, and other linear driving components such as a linear module or a linear air cylinder and the like can be adopted in other embodiments of the invention.

Referring to fig. 1, as the arrangement plate 41 continuously jacks up the round bars to move to a position far away from the feeding end, the round bars are gradually arranged in order on the support plate, and in order to determine whether each position is provided with a round bar, the vertical support plate 20 is provided with the induction sensors 21 corresponding to the tooth-shaped grooves one by one. The induction sensor 21 points to the upper side of the supporting vertical plate 20, namely the induction sensor 21 points to the position of the round rod, when the induction sensor 21 senses that the round rod is fully arranged on the supporting vertical plate 20, the positioning and arranging device stops, and the round rod arranged in order is taken down by the blanking device. In order to further ensure the neatness of the round bar and prevent the length of the round bar extending in the axial direction from being inconsistent, the centering assemblies 22 are symmetrically arranged on two sides of the supporting vertical plate 20. The centering assembly 22 comprises a horizontal cylinder 23 perpendicular to the vertical supporting plate 20, the horizontal cylinder 23 is connected with a centering plate 24, and the horizontal cylinder 23 pushes the centering plate 24 to move relatively. Because two pairs of middle plates 24 are symmetrically arranged, the round rods are clamped between the two pairs of middle plates 24, and when the horizontal air cylinder 23 pushes the two pairs of middle plates 24 to clamp the round rods towards the center, the round rods are centered, so that the round rods are neatly placed.

Further, in order to expand the application range of the positioning and aligning device, the two supporting vertical plates 20 are mounted on the frame 10 through the bidirectional translation assembly 11. That is, the vertical supporting plate 20 can be moved to both sides, so that it can support round bars having different lengths. Specifically, the bidirectional translation assembly 11 includes a linear guide rail 12 and a bidirectional screw rod 13, the supporting vertical plate 20 is slidably connected to the linear guide rail 12, the supporting vertical plate 20 is connected to two ends of the bidirectional screw rod 13 through a screw rod nut, and one end of the bidirectional screw rod 13 is connected to a rotating hand wheel 14. The linear guide rails 12 are installed at two sides of the frame 10 to realize stable support of the supporting vertical plate 20, and the bidirectional screw rod 13 is located between the two linear guide rail 12 supports to ensure that the supporting vertical plate 20 is stressed in balance and cannot be inclined in the adjusting process when the distance between the supporting vertical plates 20 is adjusted. In the invention, the distance between the supporting vertical plates 20 is required to be adjusted only when products with different sizes are replaced, so that the rotating hand wheel 14 is adopted to drive the bidirectional screw rod 13 to rotate, and the screw rod nut drives the supporting vertical plates 20 to axially move along the bidirectional screw rod 13 along with the rotation of the bidirectional screw rod 13, thereby realizing the adjustment of the distance between the supporting vertical plates 20.

The invention also provides an operation method of the round rod positioning and arranging device, and the arrangement device comprises the following steps:

the round bar is conveyed to the feeding position of the supporting vertical plate 20, and the guide mechanism 50 guides the round bar.

In the first embodiment of the present invention, the polarization mechanism 50 includes a rotating component 51 and a photoelectric sensor 53. When the device works, the conveying device puts a first round bar into a feeding position on the supporting vertical plate 20, namely a first tooth-shaped groove, the photoelectric sensor 53 is aligned with a pilot groove position on the round bar, and the rotating component 51 drives the round bar to rotate until the photoelectric sensor 53 detects the existence of the pilot groove; at this time, the alignment groove is not aligned with the photosensor 53, so the rotation member 51 continues to rotate, and the alignment groove is aligned with the photosensor 53. Since the pilot slot dimensions are known, the angle at which the rotating assembly 51 continues to rotate is determined.

In the second embodiment of the present invention, the pilot mechanism 50 includes a pilot vertical plate 54. During operation, conveyor puts into the material feeding position that supports riser 20 with first round bar from the top, and the round bar is at the in-process of whereabouts, because there is the friction between the arc surface of round bar and the vertical limit of leading positive riser 54 for the round bar is rotatory, rotates to leading the plane and leading positive riser 54 cooperation when the round bar, and the round bar can't rotate, realizes leading positive to the round bar. In other embodiments of the present invention, when the material taking mechanism 30 places the round bar into the second tooth-shaped groove, the round bar may be rotationally aligned due to the limitation of the alignment vertical plate 54, or when the arrangement plate 41 displaces the round bar into the downward tooth-shaped groove, the round bar may be rotationally aligned due to the limitation of the alignment vertical plate 54.

After the posture adjustment of the round bar is completed, the material taking toothed plate 31 is driven by the first lifting and translation assembly 32 to eject the round bar from the material feeding position to the next toothed groove. The translation cylinder 36 pushes the material taking toothed plate 31 to the lower portion of the first round rod of the material feeding position, the material taking toothed plate 31 is jacked upwards by the lifting cylinder 33, the material taking toothed plate 31 ejects the first round rod from the supporting plate, the translation cylinder 36 drives the material pulling plate 35 to retract, the lifting cylinder 33 descends and resets, the material taking toothed plate 31 descends to a height lower than the supporting vertical plate 20, the first round rod on the material taking toothed plate 31 is supported by the second tooth-shaped groove on the supporting vertical plate 20, and the round rod is taken out from the material feeding position. The tooth-shaped groove for emptying the feeding position is used for placing the next round rod.

The arrangement plate 41 is driven by the second lifting and translation assembly 42 to eject all round rods except the feeding position into the next tooth-shaped groove. Because the first round bar is already placed in the second tooth-shaped groove, the arrangement plate 41 of the arrangement mechanism 40 moves up and down and translates, and the first round bar is ejected out of the second tooth-shaped groove and placed in the third tooth-shaped groove, so that the second tooth-shaped groove is formed.

And repeating the steps of inputting the round rods and ejecting the round rods by the material taking toothed plate 31 and the arrangement toothed plate respectively, namely placing a second round rod at the material feeding position, and ejecting the second round rod at the material feeding position into a second tooth-shaped groove by the material taking plate after the second round rod is guided and corrected. The arrangement plate 41 jacks up the second round bar and the first round bar simultaneously, moves one tooth socket backwards, places the two round bars into the third tooth-shaped groove and the fourth tooth-shaped groove respectively, and repeats until the round bars are fully arranged on the support plate.

According to the round bar straightening device, the material taking plate only needs to take out a round bar from the feeding position, the round bar does not need to move for a long distance, the action is fast, the time is short, the next round bar can be placed after the round bar is taken out from the feeding position, the material taking plate can place the round bar and return the round bar in the process of guiding the round bar, meanwhile, the arrangement mechanism 40 moves all the round bars by one tooth pitch, the working time is tight, and the working efficiency is high.
