Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger goods transport apparatus for transporting clothes on a hanger in the field of apparel.

[0002]

2. Description of the Related Art Conventionally, in the field of apparel, a gravity chute used for storing hanger products in the middle of a transportation line is composed of a downhill rail 30 inclined at a steep angle as shown in FIG. The upstream end of the downhill rail 30 is arranged at the unloading position of the transport trolley 32 running on the running rail 31 installed at a high place, and a horizontal storage unit 30A is formed on the downstream side of the downhill rail 30. Has been done.

In the gravity chute, the hook F of the hanger product transported by the transport trolley 32 to the unloading position is transferred to the upstream end of the downhill rail 30, and is slid down to the downstream side by the weight of the hanger product. Is stopped by the stopper 33 provided at the downstream end of the hanger product, and after the hook F of the hanger product that has slid down the head is stopped by the stopper 33, the subsequent hanger product is placed behind the first hanger product. The horizontal storage section 30A is sequentially stored. Then, the hanger products stored in the storage unit 30A are sequentially taken out manually from the downstream side.

[0004]

SUMMARY OF THE INVENTION In the above-described gravity chute, the inclination angle of the downhill rail with respect to the horizontal plane is different from that of the downhill rail in order to allow the hook of the hanger product hung on the downhill rail to slide down. It is necessary to incline more than the static friction angle with the hook, and there is a problem that the height difference of the downhill rail between the end on the carry-in side and the end on the carry-out side becomes large.

Further, the descent speed of the hanger product sliding down the downhill rail and the line pressure acting on the hanger product stored in the storage unit act on the inclination angle of the downhill rail and between the downhill rail and the hook. Since it is determined depending on the frictional force, it is difficult to control the downhill speed and the line pressure during storage after the gravity chute is installed.

Therefore, the present invention solves the above-mentioned problems in the prior art, can convey a hanger product with a small height difference, and can reduce the line pressure when storing the hanger product, and The main object of the present invention is to provide a hanger product transfer device in which the transfer speed can be easily controlled.

[0007]

In order to achieve the above object, the hanger product transporting device of the present invention is rotatably supported with its axis inclined with respect to a horizontal plane, and hangs and transports a hook of a hanger product. A transport shaft having a smooth surface and a drive source for rotationally driving the transport shaft are provided, and an inclination angle of the axis line of the transport shaft with respect to a horizontal plane is smaller than a static friction angle between the transport shaft surface and the hook. It is set.

It is preferable that the drive source is configured so that the rotation speed of the transport shaft can be changed. It is also preferable to provide a retractable stopper that stops the hanger product by contacting the hook of the hanger product transported on the transport shaft at a protruding position. Furthermore, the upper surface of the transport shaft and one hook of the hanger product are provided. It is also preferable to provide a pressing member having guide surfaces facing each other with an interval allowing passage of minutes along the transport axis.

[0009]

[Operation] The hook of the hanger product is suspended and supplied on the upstream end side of the transport shaft. When the hook is suspended from the stopped transport shaft, the angle of inclination of the transport shaft with respect to the horizontal plane is smaller than the static friction angle between the surface of the transport shaft and the hook. doing. Then, when the transport shaft is rotated by the drive source, the surface of the transport shaft slips with respect to the hook. Then, the hook starts sliding down toward the downstream side of the transport shaft. Then, when the rotation of the transport shaft is stopped again, a static friction force acts between the hook and the surface of the transport shaft, and the hook stops at that position.

When a drive source having a structure capable of changing the rotation speed of the carrying shaft is used, the speed of the hook sliding on the surface of the carrying shaft increases or decreases in accordance with the increase or decrease in the rotating speed of the carrying shaft.
The transport speed of the hanger product can be controlled. When a retractable stopper that stops the hanger product by contacting the hook of the hanger product that is transported on the transport shaft at the protruding position is provided, the stopper is set while the transport shaft is rotating. When the hook is moved to stop the protrusion, the hooks of the subsequent hanger products also stop one after another on the upstream side of the stopped hooks, and the hanger products can be stored, and the stopper is retracted as necessary. Thus, the hanger product can be sent to the downstream side of the transport shaft from the leading side again.

Further, in the case where a pressing member having a guide surface facing the upper surface of the conveying shaft and a hook for a hanger product is provided at an interval such that the hook can pass, the conveying member is conveyed by the conveying shaft. Since the hook of the hanger product to be passed passes between the surface of the transport shaft and the guide surface of the pressing member, there is no possibility of overlapping with the hook of the subsequent hanger product to hinder the transport.

The angle is set to be smaller than the static friction angle between the surface of the transport shaft 6 and the hook F.

The upstream end of the transport shaft 6 in the transport direction, that is, the left end of the transport shaft 6 in FIG. 1 is connected to the drive source 7. The drive source 7, as shown in FIG.
The speed reducer 1 is composed of a variable speed motor 9 fixed to a support bracket 8 fixed to the end of the support rail 3 and a speed reducer 10 connected to the motor 9.
The rotation of the toothed drive pulley 11 fixed to the output shaft of 0 is transmitted to the toothed driven pulley 13 fixed to the upstream end of the conveying shaft 6 via the toothed belt 12, and the conveying shaft 6 is It is designed to be rotated. A bearing 14 that supports the transport shaft 6 is attached to the support bracket 8 at a position adjacent to the toothed driven pulley 13.

As shown in FIG. 1, an inclined relay rail is provided between the upstream side position of the transport shaft 6 and the unloading position of the transport trolley 16 traveling along the traveling rail 15 installed at a high place. 17 is installed, the upper end of the relay rail 17 receives the hook of the hanger product carried to the unloading position by the transport trolley 16 from the carrier of the transport trolley 16, and the upper surface of the relay rail 17 is received. It is made to slide down and is transferred onto the transport shaft 6 at the downstream end.

An upstream end of the carry-out rail 18 is arranged adjacent to the downstream end of the transport shaft 6. The carry-out rail 18
Is inclined to the downstream side, and its downstream end is arranged in proximity to the carry-out conveyor 19. The carry-out rail 1
8 receives the hook F of the hanger product that has moved to the downstream end of the transport shaft 6, slides down the upper surface thereof, and transfers it onto the carrier 19A of the carry-out conveyor 19.

Although not shown in FIG. 1, there are a plurality of hanger products to be transported on the transport shaft 6 at a plurality of positions along the longitudinal direction of the transport shaft 6, as shown in FIG. A retractable stopper 20 that contacts the hook F at the protruding position to stop the hanger product is arranged. The stopper 20 is connected to a drive cylinder 21 installed on one side of the transport shaft 6, and is configured to be horizontally advanced and retracted from a direction orthogonal to the axis of the transport shaft 6.

Further, as shown in FIG. 2, on the lower surface of the support rail 3, there is provided a guide surface 22 which is opposed to the upper surface of the carrying shaft 6 with a space for one hook F of the hanger product to pass therethrough.
A holding member 22 having A is attached via a mounting bracket 23. The pressing member 22 is provided over substantially the entire length of the conveying shaft 6 excluding the upstream end side, and the guide surface 22A is formed of a low friction material such as resin.

At this time, the variable speed motor 9 of the drive source 7 shown in FIG. 3 is driven to rotate the conveyor shaft 6 via the speed reducer 10, the toothed drive pulley 11, the toothed belt 12, and the toothed driven pulley 13. Then, the surface of the transport shaft 6 has a hook F of a hanger product.
As a result, the hanger product is transported toward the downstream side of the transport shaft 6. Here, when the rotation speed of the variable speed motor 9 is increased, the transportation speed of the hanger product is increased in proportion thereto, and when the variable speed motor 9 is decelerated, the transportation speed is also decreased. The speed can be smoothly controlled.

It should be noted that the rotation direction of the transport shaft 6 is preferably rotated counterclockwise in FIG. 2 so that the hook F does not easily come off from the transport shaft 6 and the transport state of the hanger product is stable. By rotating in the direction, there is no fear that a finger or the like will be caught between the arcuate receiving surface 5A of the transport shaft support member 5 and the transport shaft 6 from the side not covered by the support frame 4. Further, the upper surface of the hook F of the hanger product conveyed downstream on the conveyor shaft 6 is prevented from being lifted by the guide surface 22A of the pressing member 22, and the hook F of the subsequent hanger product overlaps and is conveyed. The operation is prevented from being disturbed.

The hook F of the hanger product moving on the transport shaft 6 is a drive cylinder 21 which is a desired position among the stoppers 20 arranged at a plurality of positions along the longitudinal direction of the transport shaft 6 shown in FIG. By projecting to a position directly below the transport shaft 6 by the stopper 20, the stopper 20 contacts the neck portion of the hook F, and the hanger product is stopped there.

Then, the movement of the subsequent hanger products conveyed from the upstream side of the stopped hanger products is sequentially stopped, and the hanger products are stored upstream of the stopper 20. Then, again the drive cylinder 21
When the stopper 20 is retracted and the hook F of the leading hanger product is released, the hanger product again starts moving to the downstream side by the rotation of the transport shaft 6.

Is transferred from the transport shaft 6 onto the carry-out rail 18, slides down on the carry-out rail 18, and is delivered to the carry device 19A of the carry-out conveyor 19. The carry-out conveyor 19 is the carry-out rail 1
The hanger product received from 8 is hung and conveyed to a predetermined place.

The stopper 20 located on the most downstream side of the transport shaft 6 is adapted to perform the stop / release operation of the hook F of the hanger product in synchronization with the operation timing of the carry-out conveyor 19. Further, the number of hanger products stored between the plurality of stoppers 20 is monitored by a full sensor, and when the number of hanger products stored on the downstream side reaches a predetermined amount, the stoppers 20 on the upstream side are provided.
To stop the movement of the hanger product to the downstream side so that the line pressure acting on the hook F of the hanger product on the leading side does not become excessive.

In the above-described embodiment, the hanger product transporting device 1 is provided with a plurality of stoppers 20 for stopping the hook F of the hanger product in the middle of the transport shaft 6 and storing it on the upstream side thereof. The stopper 20 is the transport shaft 6.

Further, in this embodiment, a pressing member 22 having a guide surface 22A facing the upper surface of the conveying shaft 6 and a hook F of a hanger product is provided along the conveying shaft 6 so as to face each other with a gap therebetween. However, if the hanger product is heavy and there is no concern that the hook will float during transportation, the pressing member 22 may be omitted to simplify the device. Further, when it is not necessary to change the transport speed of the hanger product, a drive source that drives the transport shaft 6 at a constant rotation speed may be used instead of the drive source 7 that uses the variable speed motor 9. .

[0029]

As described above, according to the hanger product transfer device of the present invention, the inclination angle of the axis of the transfer shaft with respect to the horizontal plane is set to be equal to or less than the static friction angle between the surface of the transfer shaft and the hook of the hanger product. Since it can be used, it is possible to reduce the height difference between the carry-in side and the carry-out side of the hanger product.

Further, the hanger product can be conveyed only by rotationally driving the conveyor shaft having a smooth surface by the drive source, and the hanger product can be stopped in the middle of the conveyance only by stopping the conveyor shaft. Therefore, the number of parts is small, maintenance and adjustment are easy, and the manufacturing cost can be reduced. Further, the transport speed of the hanger product can be easily controlled only by using a drive source having a structure capable of changing the rotation speed of the transport shaft.

Further, by providing a retractable stopper that comes into contact with the hook of the hanger product conveyed on the conveyor shaft at the protruding position to stop the hanger product, the hanger product can be easily stored. At that time, even if the following hanger products are stopped one after another by the stopper, the line pressure acting on the stopper is small because the transport shaft is gently inclined with respect to the horizontal plane, and a large number of hanger products can be stored. .

Further, in the case where a pressing member having a guide surface opposed to the upper surface of the transport shaft and a hook for a hanger product is provided along the transport shaft with a gap therebetween,
Since the hook of the hanger product transported by the transport shaft passes between the surface of the transport shaft and the guide surface of the pressing member, even if the hanger product is lightweight and easily shakes during transportation, There is no danger of it overlapping the hook and hindering transport.
