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 In the field of apparel, a gravity chute used for storing hanger goods in the middle of a transfer line is a hoist of a hanger goods which a transfer trolley has conveyed to an unloading position at an upstream end of a downhill rail. , And is slid down on the downhill rail to the horizontal storage unit on the downstream side by the weight of the hanger product, and stopped by the stopper provided at the downstream end of the storage unit. At that time, after the hook of the hanger product that has been slid down the top is stopped by the stopper, subsequent hanger products are stored one after another behind the first hanger product, and are manually taken out from the top one in order. ing.

The above-mentioned gravity chute has a slope of a downhill rail with respect to a horizontal plane in order to slide down a hook of a hanger product hung on the downhill rail to a downstream side.
It is necessary to incline larger than the static friction angle between the sliding surface of the downhill rail and the hook, and there is a disadvantage that the height difference of the downhill rail between the end on the loading side and the end on the unloading side becomes large. In addition, 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, depend on the inclination angle of the downhill rail and the frictional force acting between the downhill rail and the hook. After the gravity chute is installed, it is difficult to control the downhill speed and the line pressure during storage.

[0004] In order to solve the above-mentioned problem of transporting the hanger goods by the gravity chute, the applicant of the present invention has been proposed to rotate the shaft with the inclined line inclined with respect to the horizontal plane instead of the fixed downhill rail. Hanger product using a transport shaft having a smooth surface, wherein the inclination angle of the axis of the transport shaft with respect to the horizontal plane is smaller than the static friction angle between the transport shaft surface and the hook, so that the hanger product can slide down. A transfer device has been proposed and is disclosed in Japanese Patent Application No. Hei.
No. 9-194015) .

In the above-mentioned hanger article transport apparatus, when a hook of a hanger article is suspended and supplied to the upstream end side of the transport shaft, when the transport shaft is stopped, the transport angle is smaller than the static friction angle between the hook surface and the hook. The hook does not slide because the angle of inclination of the shaft with respect to the horizontal plane is small, and the hanger product is stationary at that position.

When the transport shaft is rotated by the drive source, the hook of the hanger product slides between the hook and the surface of the transport shaft to start downhill. 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.

[0007]

In the hanger goods transport device having the above-described structure, when a hanger product is stored by providing a storage portion downstream of the transport shaft, the hanger product at the top of the storage portion is stopped while the transport shaft is rotated. If the number of hanger items to be stored is large, a large line pressure will be generated, making it difficult to cut out the hanger items, and the same location on the outer surface of the rotating transport shaft will be rubbed by the hook and partially stopped. There is a problem that causes excessive wear.

Therefore, the present invention solves this problem, reduces the line pressure acting on the hanger goods stored downstream of the transport shaft, and reduces the wear on the transport shaft to withstand long-term use. An object of the present invention is to provide a hanger product transport device that can be used.

[0009]

In order to achieve the above-mentioned object, a hanger goods transport device of the present invention is supported rotatably with its axis inclined with respect to a horizontal plane, and hangs down by hanging a hook of the hanger goods. And a drive source for rotating the transport shaft.

[0010] The transport shaft is rotatably fitted to the transport shaft main body which is rotationally driven by the drive source, and is individually rotatably fitted adjacent to each other in the axial direction of the transport shaft main body. , And the inclination angle of the axis of the transport shaft with respect to the horizontal plane is set to an angle smaller than the static friction angle between the outer peripheral surface of the collar and the hook.

[0011]

The hook of the hanger is suspended from the outer peripheral surface of the collar at the upstream end of the transport shaft. In the state where the transport shaft main body is stopped, the collar externally fitted to the transport shaft main body is also stopped, and the inclination angle of the transport shaft with respect to the horizontal plane is smaller than the static friction angle between the collar surface and the hook. ,
The hook does not slip and stays in place.

When the drive shaft is rotated by the drive source, the collar is driven by the frictional force between the transport shaft and the collar.
Then , the collar starts rotating together with the transport shaft main body, and the outer peripheral surface of the collar slides with respect to the hook, and the hook starts sliding down toward the downstream side of the transport shaft.

While the hook of the hanger product is sliding down the outer peripheral surface of the collar, when an external force for preventing the hanger product or the like stopped at the downstream side from moving to the downstream side of the transport shaft is received, the hook and the hanger are moved together. The frictional force acting between the outer peripheral surface of the collar and the inner peripheral surface of the collar becomes larger than the frictional force acting between the outer peripheral surface of the transport shaft main body, and the collar hanging the hook slips with respect to the transport shaft main body. And stop.

When the collar stops, the angle of inclination of the transport shaft with respect to the horizontal plane is smaller than the static friction angle between the collar surface and the hook, so that the hook of the hanger product is held in place without slipping.

Next, when the stopper or the like is released and the hanger product is released from the external force, the collar starts rotating again, and the hook of the hanger product resumes the sliding movement toward the downstream side of the transport shaft.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing one embodiment of a hanger product transport device of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA. As shown in these drawings, the hanger product transport device 1 A support frame 3 suspended from a ceiling of the building by a suspension member 2, and a support frame 4 is attached in a longitudinal direction of the support rail 3.

As shown in FIG. 2, the lower portion of the support frame 4 is bent horizontally, and a transport shaft support member 5 is fixed at several places at intervals in the longitudinal direction of the support frame 4. It supports a transport shaft 6 for hanging the hook F of the product and sliding down.

As shown in FIG. 3, the transport shaft 6 comprises a transport shaft body 6A and a number of cylindrical collars 6B which are individually and rotatably fitted to the transport shaft body 6A. The transport shaft main body 6A has a large-diameter portion 6C having an outer diameter substantially equal to that of the collar 6B, which is disposed at several places in the axial direction at intervals, and the outer peripheral surface of the large-diameter portion 6C is shown in FIG.
As shown in (1), it is rotatably supported on the arc-shaped receiving surface 5A of the transport shaft support member 5.

The large-diameter portion 6C is detachably fixed to the transport shaft main body 6A so that the collar 6B can be incorporated between the large-diameter portions 6C of the transport shaft main body 6A. A collar 6 is provided at the downstream end of the main body 6A.
B retaining portion 6D is provided.

As shown in FIG. 1, the transport shaft 6 is provided below the support rail 3 from left to right in FIG.
It is provided in parallel and inclined. The inclination angle of the axis of the transport shaft 6 with respect to the horizontal plane is defined by the outer peripheral surface of the collar 6B and the hook F.
The angle is set smaller than the static friction angle between.

Near the upstream end of the transport shaft 6 in the transport direction,
That is, in FIG. 1, the collar is not mounted near the left end of the transport shaft 6, and the transport shaft main body 6A is exposed.
Its end is connected to the drive source 7.

As shown in FIG. 4, the drive source 7 includes a variable speed motor 9 fixed to a support bracket 8 fixed to an 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 the speed reducer 10 causes the rotation of the toothed driven pulley 11 fixed to the upstream end of the transport shaft body 6A via the toothed belt 12. The power is transmitted to the pulley 13, and the transport shaft main body 6A is driven to rotate. A bearing 14 that supports the transport shaft main body 6A at a position adjacent to the toothed driven pulley 13 is attached to the support bracket 8.

As shown in FIG. 1, an inclined relay rail is provided between an upstream position of the transport shaft 6 and an unloading position of a transport trolley 16 traveling along a traveling rail 15 installed at a high place. A hook F of the hanger goods carried to the unloading position by the transport trolley 16 is received from the transporter of the transport trolley 16 by the upstream end of the relay rail 17 and the upper surface of the relay rail 17 is provided. Is slid down and transferred to the collar 6B of the transport shaft 6 at the downstream end.

On the other hand, an upstream end of the unloading rail 18 is arranged adjacent to a downstream end of the transport shaft 6. The carry-out rail 18 is inclined to the downstream side, and its downstream end is arranged close to the carry-out conveyor 19. The unloading rail 18 receives the hook F of the hanger product that has moved on the collar 6B to the downstream end of the transport shaft 6, slides down the upper surface thereof, and transfers it onto the transporter 19A of the unloading conveyor 19.

Although not shown in FIG. 1, at a plurality of positions along the longitudinal direction of the transport shaft 6, as shown in FIG. A retractable stopper 20 for stopping the hanger product by contacting the hook F of the conveyed hanger product at the projecting position is disposed. The stopper 20 is connected to a drive cylinder 21 installed on one side of the transport shaft 6,
The transport shaft 6 is configured to be horizontally advanced and retracted from a direction perpendicular to the axis of the transport shaft 6.

Further, as shown in FIG. 2, on the lower surface of the support rail 3, a large diameter portion 6C of the transport shaft main body 6A, and
A pressing member 22 having a guide surface 22A opposed to the upper surface of the collar externally fitted to the transport shaft main body 6A and an interval at which one hook F of a hanger product can pass is attached via an attachment bracket 23. ing. The holding member 2
Numeral 2 is formed of a low friction material such as resin, and is provided over substantially the entire length of the transport area of the transport shaft 6 on which the collar is disposed.

When the hanger product is unloaded from the transfer trolley 16 shown in FIG. 1 onto the relay rail 17 at the unloading position, the hanger product is relayed. The hook F is transferred to the outer peripheral surface of the collar 6 </ b> B on the upstream end side of the transport shaft 6 while sliding down the rail 17.

At this time, the variable speed motor 9 of the drive source 7 shown in FIG. 4 is driven, and the transfer shaft body 6 is driven via the speed reducer 10, the toothed driving pulley 11, the toothed belt 12, and the toothed driven pulley 13.
A is rotated, and the externally fitted
The roller 6B rotates together with the transport shaft main body 6A due to the frictional force between the transport shaft and the collar .

Then, the hook F of the hanger product slides with respect to the outer peripheral surface of the collar 6B, and the hanger product starts sliding downward toward the downstream side of the transport shaft 6. When the hook F moves from one collar 6B to the adjacent downstream collar 6B, the hook F assumes a posture obliquely intersecting with the direction of the transport shaft 6, so that the collar 6B
It does not fall into the gap between them and be bitten.

Here, when the rotation speed of the variable speed motor 9 is increased, the speed at which the hook F of the hanger product slides down becomes:
The speed increases in proportion to this, and when the variable speed motor 9 is decelerated, the speed also decreases, and the sliding movement speed of the hanger product can be smoothly controlled by changing the rotation speed of the variable speed motor 9.

The direction of rotation of the transport shaft main body 6A is preferably rotated counterclockwise in FIG. 2 so that the hook F is less likely to fall off the outer peripheral surface of the collar 6B and the transport state of the hanger product is stabilized. By rotating in this direction, a finger or the like may be caught between the arc-shaped receiving surface 5A of the transport shaft support member 5 and the large-diameter portion 6C of the transport shaft main body 6A from the side not covered by the support frame 4. Disappears. Further, the upper surface of the hook F of the hanger product that slides downstream along the transport shaft 6 is prevented from being lifted up by the guide surface 22A of the holding member 22, and overlaps with the hook of the subsequent hanger product to slide down. Interference with operation is prevented.

The hooks F of the hanger goods moving on the collar 6B which is externally fitted to the transport shaft main body 6A are the stoppers 20 of the stoppers 20 arranged at a plurality of positions along the longitudinal direction of the transport shaft 6 shown in FIG. Drive cylinder 21 at desired position
The stopper 20 comes into contact with the neck of the hook F by intersecting and protruding to a position immediately below the transport shaft 6, and the hanger product is stopped at that position. As a result, the subsequent hanger goods that slide down from the upstream side are stopped by the hanger goods stopped by the stopper 20 and stopped one after another, and the hanger goods are stored upstream of the stopper 20. You.

When the hook F of the hanger product stops, the outer peripheral surface of the collar 6B on which the hook F is mounted and the hook F
Between the collar and the transport shaft body 6
A is larger than the frictional force acting between the two. As a result, a slip occurs between the inner peripheral surface of the collar 6B on which the stopped hook F rests and the outer peripheral surface of the transport shaft main body 6A which continues to rotate, and the rotation of the collar 6B stops.

And the hook F of the hanger product is
When the rotation of the collar 6B is stopped, the collar 6B is held in place by the static friction force acting between the collar 6B and the collar outer peripheral surface 6B, so that line pressure is not exerted on the hanger goods stopped downstream. Further, the stop of the collar 6B on which the hook F is mounted prevents partial wear of the outer peripheral surface.

Next, when the drive cylinder 21 retracts the stopper 20 and releases the hook H of the leading hanger product, the collar 6B on which the hook F is mounted is rotated again by the frictional force acting between the collar 6B and the transport shaft body 6A. Is started, and the hanger product starts sliding down again toward the downstream side of the transport shaft 6.

When the hook F of the hanger product moves to the downstream end of the transport shaft 6 shown in FIG.
Is transferred onto the carry-out rail 18 from the collar 6B of the transport shaft 6 and slides down on the carry-out rail 18 and is transferred to the carrying device 19A of the carry-out conveyor 19. The unloading conveyor 19
Suspends the hanger product received from the unloading rail 18 and transports it to a predetermined place.

The stopper 20 located at the most downstream side of the transport shaft 6 stops and releases the hook F of the hanger product in synchronization with the operation timing of the unloading conveyor 19. In addition, the number of hanger items stored between the plurality of stoppers 20 is monitored by a full sensor (not shown), and when the number of hanger items stored on the downstream side reaches a predetermined amount, the number of hanger items is on the upstream side. The stopper 20 is made to protrude to stop the movement of the hanger product on 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, as shown in FIG. 2, the outer peripheral surface of the large diameter portion 6C provided at several places of the transport shaft main body 6A is supported by the arc-shaped receiving surface 5A of the transport shaft support member 5. As shown in FIG. 6, without providing the large-diameter portion 6 </ b> C in the transport shaft main body 6 </ b> A, two lower left and right outer peripheral surfaces of the collar 6 </ b> B are parallel to the transport support member 5 at several places of the transport shaft 6. A pair of small-diameter rollers 5 rotatably mounted around an axis
The collar 6B may be supported over the entire transport area of the transport shaft 6 by being supported by B and 5B.

In this case, the rollers 5B, 5B use a ball bearing or the like to minimize the rotational friction so that the collar 6B supported by the rollers 5B, 5B can rotate together with the rotary shaft body 6A. There is a need.

In the above-described embodiment, the hanger product hook F
Are stopped and a plurality of stoppers 20 are provided for storage on the upstream side, but only one stopper 20 may be provided on the downstream end side of the transport shaft 6, or the stopper 20 is not provided. May be used only for the purpose of transporting the hanger product.

Further, in the present embodiment, the guide surface 22 is opposed to the outer peripheral surface of the collar 6B which is externally fitted to the transport shaft main body 6A with an interval allowing one hook F of a hanger product to pass therethrough.
Although the holding member 22 having A is provided along the transport shaft 6, if the hanger product is heavy and there is no fear that the hook will float during the transfer, the holding member 22 is provided.
Can be omitted to simplify the device. Also,
When it is not necessary to change the transport speed of the hanger product, a drive source that drives the transport shaft main body 6A at a constant rotation speed may be used instead of the drive source 7 using the variable speed motor 9.

[0042]

As described above, according to the hanger product transport device of the present invention, the transport shaft main body whose transport shaft is rotationally driven by the drive source is adjacent to the transport shaft main body in the axial direction. It is composed of a large number of cylindrical collars that are individually rotatably fitted to the outside and hooks of the hanger product are hung on the outer peripheral surface. When the downhill movement is prevented, the rotation of the collar on which the hook of the leading hanger product and the subsequent hanger product is mounted is stopped, and the respective hooks are held on the stopped collar by static friction. it can. As a result, the line pressure acting on the hanger goods stored on the downstream side can be reduced, and the work of cutting out the stored hanger goods from the downstream end can be easily performed.

Even if the hanger product is stopped at a fixed position on the transport shaft for a long time while the transport shaft is rotated, the collar on which the hanger of the stopped hanger product is mounted is moved relative to the transport shaft main body. Slip and stop, it is possible to prevent partial wear of the outer peripheral surface of the collar that is in contact with the hook, and the inner peripheral surface of the collar is in contact with the outer peripheral surface of the transport shaft body in surface contact with the contact surface. Pressure can be kept low,
There is little wear between the inner peripheral surface of the collar and the outer peripheral surface of the transport shaft main body, and it can withstand long-term use.
