The present invention relates to a transfer device for a hanger manufacturing apparatus, and relates to a transfer device for a hanger manufacturing apparatus that the subsequent process is performed without errors since the aligned hangers are transferred without shaking while the manufactured hangers are automatically aligned and transferred.

In general, disposable hangers manufactured by bending wires are mainly used for displaying clothes or carrying clothes for short periods of time at shops that sell clothes or provide services such as laundry, rather than hanging clothes at home. .

Such a disposable hanger, when the rolled wire is supplied to the hanger molding machine, one end is bent in the form of a hook, the whole is bent in a triangular form, and the other end is manufactured in the form of the bottom of the hook.

The hanger produced in the molding machine is sprayed around the coating as needed. To apply paint around the hanger, the hangers must be hung so that the hangers produced are aligned at regular intervals.

However, in the related art, a plurality of coat hangers have to be aligned one by one at regular intervals through hangers, and thus the work is very difficult and time consuming.

In order to solve such a conventional problem, a transfer device (patent application No. 10-2008-122044) for a hanger manufacturing apparatus as shown in FIG. 1 has been developed.

When the hanger 1 is manufactured in the molding machine 3, the transfer device for the hanger manufacturing apparatus of the related art hangs on its end while the hook 2 of the hanger 1 falls to the upper side of the pipe guide 6. The clothes hanger 1 caught on the pipe guide 6 is transported downward along the pipe guide 6 and caught on the alignment bar 4. When a plurality of clothes hangers 1 are caught on the alignment bar 4, the drive motor 7 is rotated to rotate the alignment bar 4, so that the clothes hangers 1 follow the spiral groove 5 of the alignment bar 4. It is aligned in the longitudinal direction of the alignment bar 4 while being transported.

A male screw portion 66 is formed at an end of the second cylinder rod 65, and a nut 67 is fastened to the male screw portion 66 to prevent the restriction block 68 from being separated.

The limiting block 68 allows the stroke length of the second cylinder rod 65 to be made only within a predetermined width. Therefore, the forward and backward distance of the rack 62 is limited by the limiting block 68 so that it is driven only by the limited width of the alignment conveyor 50.

To increase the spacing between the hangers 1, the spacing blocks 55 may be replaced to increase the spacing between the insertion grooves 56. At this time, as the interval between the insertion grooves 56 is increased, the second cylinder rod 65 is provided with a limiting block 68 having a smaller width. As the width of the restriction block 68 is reduced, the stroke distance of the second cylinder rod 65 is increased, and accordingly, the forward and backward distance of the rack 62 is increased, so that the driving distance of the alignment conveyor 50 can be increased. have.

The transfer part 70 is installed on the upper part of the table 30 and lifts and transfers the upper part of the hangers 1 aligned to the alignment conveyor 50.

The transfer part 70 is provided with an elevating base 71 provided so as to elevate on the upper portion of the table 30. The lifting cylinder 72 is provided in the lower part of the lifting base 71 to raise and lower it. The rodless cylinder 73 is installed in the upper part of the lifting base 71. The guide 74 is installed in the rodless cylinder 73 so as to reciprocate along this, and the guide 74 is provided with a rotation cylinder 75. The rotating cylinder 75 is provided with the rotating shaft 76 so that it may rotate in a horizontal direction by this. The fixing plate 77 is fixed to the upper end of the rotating shaft 76, and a pair of hooks 78 are fixed to the fixing plate 77 in the horizontal direction. The pair of hooks 78 are supported on the lower side of the hook 2, which is upper when the hanger 1 is viewed as a whole.

The hanger lower support part 80 is provided so that it may be elevated to the transfer material part 70. The lower hanger support part 80 supports the upper part of the hangers 1 by lifting the hook 78 to press and support the lower part of the hangers 1. In this way, the upper and lower portions of the hangers 1 to be transferred together with the hook 78 is elastically supported.

The cylinder rod 83 of the hanger support cylinder 82 is connected to the lifting plate 81, and is lifted along the rotation shaft 76 when the hanger support cylinder 82 is operated. The auxiliary hook 84 is installed so that a pair is connected to the elevating plate 81 and parallel to the hook 78 of the transfer part 70. The auxiliary hook 84 is lowered when the upper part of the hangers 1 is supported by the hook 78 to press and support the lower part of the hangers 1.

When the hanger 1 manufactured by the molding machine falls to the chute 40 side as shown by the arrow (a) of FIG. 5A, the transfer plate 42 of the chute 40 of the present invention having such a structure has a guide plate 42. It is guided along and falls to the alignment conveyor (50). The hanger 1 falling into the alignment conveyor 50 maintains a vertical position while its both ends are inserted into the corresponding insertion grooves 56 of the space keeping blocks 55.

When it is confirmed by the proximity sensor 57 that the clothes hanger 1 is inserted into the insertion grooves 56 of the interval maintaining block 55, the operation cylinder 63 of the conveyor driving unit 60 is operated. First, as shown in FIG. 5B, the first cylinder rod 64 and the second cylinder rod 65 are advanced in the direction of an arrow b. As the rack 62 is advanced by the first cylinder rod 64, the pinion 61 is rotated, and the drive shaft 51 is rotated by the pinion 61. The ratchet bearing 52 provided on the drive shaft 51 does not transmit the rotational force of the drive shaft 51 to the sprocket 53, and only the drive shaft 51 is idle.

When the first cylinder rod 64 and the second cylinder rod 65 are reversed in the direction of the arrow c while the hydraulic pressure acts on the working cylinder 63 in reverse, the rack 62 is reversed to rotate the pinion 61. The drive shaft 51 is rotated by the pinion 61, and the sprocket 53 is rotated while the rotational force of the drive shaft 51 is transmitted to the ratchet bearing 52. When the sprocket 53 is rotated, the chain 54 is driven, and the space keeping blocks 55 installed in the chain 54 are moved in the direction of the arrow d.

When the first cylinder rod 64 and the second cylinder rod 65 of the operation cylinder 63 are set backward, the space keeping block 55 is transferred only by the distance between the insertion grooves 56. Accordingly, the lower side of the chute 40 corresponds to the inserted hanger 1 and another insertion groove 56 adjacent thereto.

In this way, when the alignment conveyor 50 is rotated by a predetermined distance and stops, another hanger 1 is dropped from the chute 40 in the direction of the arrow e, and the dropped hanger 1 is inserted into the corresponding insertion groove 56. As it is inserted into the field, it is kept upright. In this manner, the plurality of hangers 1 are arranged at regular intervals on the top of the alignment conveyor 50.

When the plurality of hangers 1 are aligned on the alignment conveyor 50, the rodless cylinder 73 of the transfer part 70 is operated as shown in FIG. 6A to hang the hook 78 and the auxiliary hook 84 on the hanger 1. To the field. When the pair of hooks 78 and the auxiliary hooks 84 enter the interior of the hangers 1 to be loaded, the lifting cylinder 72 is operated to lift the hook 78 as shown in FIG. 6B, and thus the hanger 1 ) Are suspended from the hook groove 78 while being separated from the insertion grooves 56 of the space maintaining block 55.

When the hangers 1 are suspended on the hook 78, the hanger support cylinder 82 is operated as shown in FIG. 6C to lower the auxiliary hook 84. Here, the lowering distance of the auxiliary hook 84 may be such that the lower portion of the hangers 1 is elastically supported by the auxiliary hook 84. Hangers 1 to be transferred are supported very stably because the upper both sides are supported by the hook 78 and the lower both sides are supported by the auxiliary hook 84.

When the auxiliary hook 84 is lowered to press and support the lower part of the hanger 1, the rodless cylinder 73 is operated as shown in FIG. 6D to reverse the hook 78 and the auxiliary hook 84, and FIG. 6E. As described above, the rotation cylinder 75 is operated to rotate the hook 78 and the auxiliary hook 84 by 180 ° in the horizontal direction. The rotated hook 78 and auxiliary hook 84 are transferred to the arm (not shown) side of the hanger jig (not shown) to transfer the hangers.

This invention has the following advantages.

First, when the hanger 1 is dropped into the alignment conveyor 50 through the chute 40 and inserted into the insertion groove 56 of the space keeping block 55 at the lower portion thereof, the rack 62 of the conveyor drive unit 60 is closed. Actuated to drive the alignment conveyor 50 by the set distance, so that the subsequently-hanging hanger 1 is inserted into the next insertion groove, whereby a plurality of hangers 1 are inserted into the alignment conveyor 50. The grooves 56 are sequentially inserted and aligned.

Therefore, since the hangers 1 are aligned while being inserted into the insertion grooves 56 of the interval maintaining blocks 55 one by one, the separation distance between the hangers 1 is assured, and the alignment state is not disturbed even by an external impact.

In addition, when the upper part of the hangers 1 hangs on the hook 78 of the transfer part 70, the auxiliary hook 84 of the lower part of the hanger support 80 is lowered to press and support the lower part of the hangers 1.

The upper part of the hangers 1 is thus supported by two hooks 78 and the lower part of the hangers 1 is supported by two auxiliary hooks 84. Since the upper and lower portions of the hangers 1 are stably supported by the hook 78 and the auxiliary hook 84, the aligned hangers 1 are not disturbed during the transfer and rotation of the transfer part 70.

Therefore, since the hangers 1 are transferred from the aligned state to the subsequent process, problems such as poor coating due to misalignment are prevented.
