Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger feeding device for feeding out hangers retained in an engaged state by an open annular hook portion one by one at a constant pitch. It is suitable for use as a product feeding unit for sorting systems such as automatic storage warehouses that automatically store and store.

[0002]

2. Description of the Related Art Generally, in an automatic storage warehouse in which clothes such as suits are automatically put in and out, a trolley conveyor is used as a main transport means in the warehouse, and a horizontal suspension bar is installed between a pair of front and rear trolleys. By the carrier, a plurality of clothes are hung on the horizontal suspension bar via the hangers, respectively, and transported to a required site, and the carrier itself or the horizontal suspension bar removed from the carrier is used as a storage unit. It is designed to be stored and taken out from the storage shelves via a crane.

In such an automated warehouse, for example, incoming garments are sent to the sorting system section in units of hangers by using an inclined conveyance path, and a fixed number of clothes are hung on a horizontal hanging bar of the carrier, or products are hung. If the hanger units are randomly fed through the inclined transport path, such as when sorting by type and size, the subsequent operations may be hindered.
However, in the feeding using the slanted conveyance path, the feeding is often random at the stage of carrying in the conveyance path.
Even if the carry-in is carried out at a constant pitch by an automatic means, the clothes-hanging hanger engages with the open annular hook part and slides down by its own weight. It is often not possible to do this, and the hangers on the front and back are often stacked.

Therefore, conventionally, a hanger that is randomly sent is temporarily retained in a retaining portion provided near the end of the inclined conveying path, and a disc with a spiral groove is disposed on the retaining portion. By intermittently rotating with a motor, the top of the hook portion of the leading hanger that has stayed is inserted into the spiral groove of the disc and sent out, so that the hangers are sequentially fed out one by one from the leading side at a fixed pitch. A separate device has been proposed (Jitsuko Sho 56-46).
No. 71).

[0005]

However, in the above-proposed separate device, since the open annular hook portion of the hanger is generally a thin line, the distance and direction of the top portions of the hook portions engaged with the retaining portion are different. There are many cases where the discs are not aligned and come into close contact with each other. When the disc is rotated, the hook part does not fit into the spiral groove and spins idle, or conversely, two hook parts overlap to form a spiral groove. There was a problem in that the disc could not be fitted reliably and the constant pitch could not be delivered, and further the malfunction of the disk due to the hooking of the hook portion was likely to occur.

In view of the above-mentioned circumstances, an object of the present invention is a hanger feeding device for sequentially feeding out hangers retained in an engaged state by an open annular hook portion, and is not affected by the arrangement state of the hook portions in the retention portion. The purpose of the present invention is to provide a hanger capable of reliably catching the hangers one by one and sending the hangers at a constant pitch, and having excellent operation reliability.

[0007]

In order to achieve the above object, a hanger feeding device according to the first aspect of the present invention comprises a rotary drive shaft inclined downward in the feed direction, and drive means for intermittently driving the rotary drive shaft. And a hanger feeding slanting rod for sliding down the hanger engaged with the open annular hook portion by its own weight.The rotary drive shaft is fixed to the spiral blade plate and higher than the fixed position. Is connected to the lower end of the hanger feeding slant rod, and forms a retaining portion of the hanger fed from the hanger feeding slant rod between the connecting portion and the spiral blade plate, and the rotary drive shaft With the rotation of
The starting end of the spiral blade is inserted from below between the open annular hook portions of the leading and the next hangers in the hanger retaining portion to rotate, whereby the leading hanger moves forward through the spiral blade plate. It is configured to be paid out.

In the structure of the first aspect of the present invention, the hanger fed into the hanger retaining portion of the rotary drive shaft from the hanger feeding slant rod has the spiral blade plate of the rotary drive shaft as a stopper, and the hanger retaining portion is inclined. Along the way, the spiral blades are wound in the open annular hook portion of the leading hanger and fed forward when the rotary drive shaft is intermittently rotated. It is possible to send out a fixed pitch for each book. In this delivery, even if the hooks of the first and second hangers in the hanger retention portion are in close contact with each other on the top side, no problem will occur.

That is, the hanger has a shape in which the hanger main body side is overlapped at the slanted hanger retention portion. However, generally, the front and rear width of the hanger main body side in which hanging articles such as clothes are hung on a thin open annular hook portion is significantly. Because it is big
The open loop hooks of adjacent hangers are always open at the bottom, even if they are in close contact at the top. In the first aspect of the present invention, the start end of the spiral blade plate is interrupted from below between the hook portions of the leading and the next hangers in the hanger retention portion as the rotary drive shaft rotates. Since the matching hook portion is always open on the lower side, the above interruption is ensured, and the spiral blade only winds the hook portion of the leading hanger.

According to a second aspect of the present invention, in the hanger feeding device according to the first aspect of the present invention, the spiral blade plate has a spiral length which is directly continuous in a radial direction with respect to a peripheral surface of the rotary drive shaft. Since it is set shorter than the circumference, the open annular hook portion of the wound hanger can be reliably separated from the spiral blade plate by one rotation of the spiral blade plate.

According to a third aspect of the present invention, in the hanger feeding device according to the second aspect of the present invention, the spiral blade plate is extended in a tail shape with its distal end side separated from the peripheral surface of the rotary drive shaft, and extends from the start end to the end. The spiral length is set to be longer than one revolution of the rotation drive shaft. Therefore, in the standby posture (stopped posture) before the rotation of the spiral blade, when the start end is positioned obliquely downward, the spiral length directly continuous with the peripheral surface of the rotary drive shaft in the radial direction as described above is Even if it is shorter than one round, the lower part of the open looped hook part of the leading hanger in the hanger retention part is positioned by contacting with the tail-shaped extension part on the terminal side. The lower parts of both hooks of the hanger are always set in a substantially constant position, so that the starting end of the spiral blade in the standby position always faces the lower parts of the hooks.

According to a fourth aspect of the present invention, in the hanger feeding device according to any of the first to third aspects of the present invention, the base end of the open ring portion of the open ring hook portion of the hanger engaged with the hanger retaining portion of the rotary drive shaft. Since the rotation direction from the side to the tip side and the rotation direction of the rotary drive shaft are set to coincide with each other, when the rotary drive shaft is rotated, the starting end of the spiral blade plate strikes the tip of the hook portion. Even if the hooks of both the first and second hangers are vertically stacked on the top side, the starting end of the spiral blade advances so as to remove this overlap.

According to a fifth aspect of the present invention, in the hanger feeding device according to any one of the first to fourth aspects, the hanger retaining portion of the rotary drive shaft has a larger outer diameter than the upper and lower hanger engaging portions. Therefore, in the hanger retention part, the displacement of the open annular hook part of the engaged hanger in the twisting direction is unlikely to occur, and it is possible to more reliably deliver each one by the spiral blade plate, while in the upper and lower hanger engaged parts. Since the hanger has a low resistance to movement, it can move more quickly along the slope due to its own weight.

According to a sixth aspect of the present invention, in the hanger feeding device according to any of the first to fifth aspects of the present invention, the rotary drive shaft to which the spiral blade plate is fixed constitutes a hollow first rotary shaft, and The second rotary shaft is inserted into the rotary shaft, and the spiral blade plate is fixed to the tip of the first rotary shaft,
Since the protruding portion of the second rotating shaft protruding from the tip of the first rotating shaft forms a screw shaft and has drive means for rotating the second rotating shaft independently of the first rotating shaft 1, By the spiral blade of the rotary shaft, the hanger fed from the hanger retention portion can be rapidly fed to the target site by the spiral guiding action by the rotation of the screw shaft of the second rotary shaft.

In a seventh aspect of the present invention, in the hanger feeding device of the sixth aspect of the invention, the hanger conveying device is provided near the tip of the screw shaft of the second rotary shaft along the direction intersecting the axial direction of the second rotary shaft in plan view. A path is provided, and the spiral direction of the screw shaft is set to be substantially orthogonal to the transport direction of the hanger transport path in plan view. Therefore, when the hanger fed from the hanger retention part by the spiral blade of the first rotating shaft is sent to the hanger conveying path by the rotation of the screw shaft of the second rotating shaft, the open annular hook part of the hanger is spirally rugged on the screw shaft. Since the upper side is engaged with the hook portion, the direction of the hook portion is along the spiral direction of the screw shaft in a plan view, but since this direction is substantially orthogonal to the transport direction of the hanger transport path, The hook portion can be easily engaged with the hanger suspension portion of the hanger conveyance path simply by dropping it from the tip of the screw shaft. That is, the hanger is automatically set by the screw shaft so as to be easily transferred to the next hanger conveyance path.

It is configured to rotate intermittently via a and 9b and the endless belt 9.

However, as shown in FIGS. 1 and 3, at the position of the flange portion 12a of the hollow shaft 12 in the first rotary shaft 1, the hanger feeding slant has been arranged with a downward slope from an oblique direction. The lower end 4a of the rod 4 is in non-contact with the flange portion.
The hanger stays so that the hanger 10 (see FIGS. 4 and 5) that is carried over from the hanger feeding slanting rod 4 stays between the connection part and the spiral blade plate 3 so as to cover the hanger 12a. It constitutes part 1a. The hanger retaining portion 1a has a larger outer diameter than the hanger feeding slanting rod 4 and the screw shaft 2a of the second rotating shaft 2 described later by fitting the thick-walled cylindrical member 13.

As shown in FIG. 2, the second rotary shaft 2 has a shaft 21 rotatably inserted into the first rotary shaft 1 such that the base end side of the shaft 21 is rotatably held by a bearing 8b.
The base end of 21 is a variable speed motor 7 via a coupling 71b.
The driven pulley 9b which is connected to the rotary shaft 70b of b and is integrated with the first rotary shaft 1 is movably supported by a bearing 8c, and the first rotary shaft 1 is driven by the operation of the motor 7b. It is designed to rotate independently of.
Further, the tip end side of the shaft 21 projects outward from the tip end of the first rotary shaft 1, and the spiral ridge 22 is formed on the outer periphery of this projecting portion.
The screw shaft 2a is configured by fitting the pipe shaft 22 having a through the pin 23 so as to be integrally rotatable. The spiral direction of the spiral ridge 22a on the screw shaft 2a in plan view is set to be substantially orthogonal to the transport direction of the trolley conveyor (extending direction of the guide rail 5).

In the above structure, as shown in FIG. 5, the hanger 10 on which the clothes S such as a suit is hung has an open loop hook portion.
In the state where 10a is engaged with the feeding slanting rod 4, the feeding slanting rod 4 slides down by its own weight along the inclination, and the first rotating shaft 1
Sent to the hanger retention section 1a of the spiral blade plate 3
Since it functions as a stopper, as shown in FIGS. 3 and 5, with the open annular hook portion 10a of the leading hanger 10 in contact with the spiral blade plate 3, the lower side along the slope of the hanger retention portion 1a. It stays in sequence so as to be connected in order. The orientation of the open annular hook portion 10a engaged with the hanger retention portion 1a is such that the circumferential direction from the base end side to the tip end side is the rotation direction of the first rotary shaft 1 (arrows in FIGS. 1, 4 and 5). It is set in advance at the stage of loading into the hanger feeding slanting rod 4 so as to coincide with the (a direction).

On the other hand, the first rotary shaft 1 is intermittently rotated according to the feeding pitch (time interval) of the hanger 10 required on the destination side by the control of the controller of the two-phase stepping motor 7a which controls the rotational driving of the first rotary shaft 1. Also, it is set so that it will stop exactly once when it is activated. Further, in the stopped state of the first rotary shaft 1, as shown in FIGS.
As shown in FIG. 5, the starting end 3a of the spiral blade plate 3 is set to a rotational position facing in the radial direction with respect to the open ring part of the open ring hook part 10a of the hanger 10 in the hanger retention part 1a. On the other hand, the second rotary shaft 2 is set to be continuously driven to rotate while the hanger 10 is continuously fed by the intermittent rotation of the first rotary shaft 1.

Thus, when the first rotating shaft 1 is rotated once in the direction of arrow a in FIGS. 1 and 5, with the number of hangers 10 ... The starting end 3a is interrupted from below between the open annular hook portions 10a, 10a of the leading and the next hangers 10, 10 in the hanger retention portion 1a, and the open annular hook portion 10 of the leading hanger 10 is interrupted.
a is wound around the spiral blade 3, so that only the leading hanger 10 leaves the hanger retention portion 1a and is sent forward. Then, the sent-out hanger 10 rides on the screw shaft 2a of the second rotating shaft 2 and rapidly moves forward by the spiral guiding action of the spiral ridge 22a, and a predetermined amount from the tip of the screw shaft 2a. Transferred to the hanger transport path.

In the present embodiment, the hanger transfer path is a trolley conveyor in which the carrier 50 runs along the guide rail 5 by the pulling force of the endless rotating body 52, and the horizontal suspension bar 51 along the transfer direction of the carrier 50. Screw shaft 2
The hook portion 10a of the hanger 10 delivered from the screw shaft 2a is configured to fall into the horizontal suspension bar 51 and engage with the horizontal suspension bar 51 when passing just below the tip of a. Therefore, in order that a predetermined number of hangers 10 are transferred to the horizontal suspension bar 51 during the passage of the carrier 50, the intermittent rotation of the first rotary shaft 1 corresponding to the operating speed and passage time of the carrier 50. The start timing, the continuation time, the intermittent operation pitch (time interval), and the rotation speed of the second rotating shaft 2 are set.

When the first rotary shaft 1 is stopped, as shown in FIG. 5, the hook portions 10a, 10a of the first and second hangers 10, 10 in the hanger retention portion 1a are in close contact with each other on the top side. Hanger body with a large front and back width
Due to the overlapping of the 10b side, the lower side of both the hook portions 10a, 10a is always opened. Further, the lower part of the hook portion 10a of the leading hanger 10 is positioned by contacting with the tail-shaped extending portion 32 of the spiral blade plate 3, and each hook portion 10a is engaged with the hanger retaining portion 1a having a large outer diameter and twisted. Since the displacement in the reciprocating direction is unlikely to occur, the lower portions of the leading and next hook portions 10a, 10a are always at substantially constant positions. Therefore, in the spiral blade plate 3, the leading end 3a is always in the standby state, and the leading and the next hook portions 10a,
It faces between the open lower side of 10a, and there is no concern that the starting end 3a will interfere with either of the hook portions 10a, 10a at the start of rotation to cause winding failure or simultaneous winding of two wires.

FIG. 6 shows the movement of the spiral blade plate 3 caused by the rotation of the first rotary shaft 1 in the standby state (FIG. 6a), 1/4 rotation (FIG. 6b), 2/4 rotation (FIG. 6c), 3 / 4 turn (Fig. 6d)
Is shown at each stage. As can be seen from these figures, the starting end 3a of the spiral blade plate 3 moves so as to circulate from the base end side to the tip end side of the hook portion 10a engaged with the hanger retention portion 1a. It is impossible to hit the tip, and even if the hook portions at the top and the next are accidentally overlapped vertically on the top side, the overlap is removed by the advance of the start end 3a.

Further, since the spiral length of the spiral blade plate 3 and the boss portion 30 directly continuous in the radial direction is shorter than one turn (about 7/8 turns in this embodiment), the spiral blade plate 3 is The open annular hook portion 10a, which is rolled up in the
Completely disengaged from the spiral blade 3 before / 4 rotation,
By the screw shaft 2a, the first rotation shaft 1 makes one rotation and is transferred to the next conveyance path until it stops. Therefore, the pitch of the intermittent rotation of the first rotary shaft 1 is shortened, and for example, when the carrier 50 is completed to be transferred to the horizontal suspension bar 51 during traveling, a large number of hangers are provided within a fixed time. It is possible to send out 10 ...

A hanger 10 mounted on the screw shaft 2a
Engages with the spiral ridge 22a at the upper portion of the hook portion 10a, it moves forward due to the propulsive force generated by the rotation of the screw shaft 2a in the direction of arrow b in FIGS. The spiral protrusions 22a are forcibly oriented along the spiral direction in plan view. Therefore, the hook portion 10a is oriented in the transport direction of the next hanger transport path to be transferred, that is, in the present embodiment, the direction substantially orthogonal to the direction of the horizontal suspension bar 51 of the carrier 50 in plan view. Therefore, as shown in FIG. 4, the open annular hook portion 10a can be easily and securely engaged with the hanger suspension portion such as the horizontal suspension bar 51 by simply dropping it from the tip of the screw shaft 2a.

In the above embodiment, the hanger transport path for transferring the hanger sent out by the hanger feeding device is the trolley conveyor in which the carrier 50 runs along the guide rail 5, but in the present invention, for example, Various other configurations can be adopted, such as a fixed type in which the hanger 10 to which the open annular hook portion 10a is engaged is moved by its own weight along the inclination. Thus, the carrying direction of these hanger carrying paths can be variously set with respect to the drawing direction of the hanger 10 by the hanger drawing device of the present invention,
Particularly, in the seventh aspect of the invention, the spiral direction and the rotation direction of the screw shaft 2a are determined corresponding to the transport direction.

In the above embodiment, the rotary drive shaft for fixing the spiral blade plate 3 is the hollow first rotary shaft 1, and the second rotary shaft in which the projecting end portion forms the screw shaft 2a in the first rotary shaft 1. Although the structure in which 2 is inserted is shown, in the first to fifth inventions, for example, the spiral blade plate 3 is fixed to the solid rotary drive shaft, and the rotary drive shaft is integrated with the rotary drive shaft below the fixed portion. The guide rod may be extended, or instead of the guide rod, various starter portions of other hanger transport paths may be connected so that the hanger can be transferred, and various other configurations without using the second rotary shaft 2 can be adopted. .

Further, in the present invention, the screw shaft 2a having a spiral groove instead of the spiral projection 22a is used, or in the structure having the first rotary shaft 1 and the second rotary shaft 2, the outer first rotary shaft The rotational driving force of the driving means may be transmitted to the shaft 1 via a chain or a gear mechanism. In addition, in the hanger feeding device of the present invention, the shape of the spiral blade plate 3, the disposition of the hanger feeding slant rod 4 and the connection configuration with respect to the first rotation shaft 1, and the member configurations of the first and second rotation shafts 1 and 2. Various design changes can be made to the detailed structure such as the support structure other than the embodiment.
