It has a plurality of hangers that are movably suspended from each other, and a plurality of engagement members that engage each hanger separately at predetermined intervals, and each engagement member is moved back and forth along the rail. , a transfer mechanism that transfers each hanger a predetermined distance as the hanger moves forward, and a spring that is provided along the rail and makes elastic contact with the rotating body corresponding to each hanger placed at a transfer position by the transfer mechanism. It is characterized by having the following.

(Function) Therefore, according to the alignment device of this invention, each hanger transferred with the forward movement of the engaging member is reliably brought to the respective transfer position by the elastic contact of the elastic member with the rotating body. The hangers are held stationary, and in this state, a predetermined distance is maintained between adjacent hangers.

(Example) Hereinafter, an example in which this invention is embodied in a hanger conveyor for sewing processing will be described based on the drawings.

As shown in Fig. 2, a plurality of processing tables 1 equipped with sewing machines, etc. are arranged at equal intervals in a garment factory, and a rail 2 is laid above each processing table 1. . The rail 2 is constructed of a rectangular ring shape made of pipe material and includes a workpiece loading section 3 occupying a predetermined length range, a plurality of stations 4 located on the sides of each processing table 1, and a workpiece loading section 5.

FIG. 3 shows one long side of the rail 2 that includes the workpiece loading section 3 and the workpiece unloading section 5. A three-stage lifting mechanism 6 is arranged on the rail 2 that is continuous with the workpiece loading section 5. . As shown in FIG. 4, this lifting mechanism 6 includes a bent rail portion 7 formed by bending pipe material 3 constituting a part of the rail 2 into three stages, and a rail 2 on the upper end side of the rail portion 7.
An air cylinder 8 connected above, a chain 10 inserted into the bent rail part 7 and connected at one end to the piston rod 9 of the air cylinder 8, and three pieces arranged on the chain 10 at predetermined equal intervals. and an engaging claw 11 that is rotatable forward (towards the air cylinder 8). As shown in FIG. 3, a descending slope section 12 is connected to the three-stage lifting mechanism 6 side of the workpiece loading section 3, and a two-stage descending slope section 14 is connected to the loading section 3 on the opposite side. A lifting mechanism 13 is connected.

The configuration of the hanger alignment device of this embodiment, which is arranged corresponding to the workpiece loading section 3, is as follows:
This will be explained based on the diagram. The work loading section 3 of the rail 2 is connected to the ceiling frame 1 via a plurality of hanging members 15.
It is supported in a horizontal state below 6. rail 2
A plurality of hangers 17 are movably suspended from rotating bodies 18 at their upper ends, and grips 19 for attaching sewing workpieces (not shown) are rotatably attached to their lower ends. . A regulating plate 20 is fixed to each hanging member 15 so as to extend parallel to the rail 2, and by fitting from above into the groove of each rotating body 18, the rotating body 18 is restricted from separating upward from the rail 2.

An air cylinder 21 is disposed on the descending slope part 14 of the rail 2, and although not shown, its piston rod has a piston rod that extends inside the rail 2 to approximately the same length as the loading part 3, similar to the three-stage lifting mechanism 6. One end of the extending chain is connected. On this chain, a plurality of engagement claws 22 as engagement members having the same configuration as the engagement claws 11 of the three-stage lifting mechanism 6 are rotatably supported at predetermined equal intervals, and each hanger 17 rotating bodies 18 separately from the sides. The air cylinder 21, the chain, and the engagement claw 22 constitute a transfer mechanism, and each engagement claw 22 is reciprocated along the rail 2 based on the operation of the air cylinder 21. During forward movement to the left in FIG. 1, each hanger 17 is moved to the left by a predetermined distance by engaging the engaging claw 22 with the rotating body 18 in an upright state. Further, during the backward movement, each engaging pawl 22 falls forward due to engagement with the rotary body 18, and then returns to the rear position of the rotary body 18.

A plurality of wire springs 23 as elastic members are arranged in rows at predetermined equal intervals on both sides of the regulating plate 20 so as to correspond to the transfer position of each hanger 17 by the transfer mechanism. As shown in FIGS. 5 and 6, one end of each wire spring 23 is fixed to the regulating plate 20 by a stop pin 24, and the intermediate portion thereof is in elastic contact with the inner surface of the groove of the rotating body 18. The elasticity of each wire spring 23 causes each hanger 17 to be stopped and held at the transfer position by the transfer mechanism via the rotating body 18. Therefore, as shown in FIG. 1, a predetermined distance is ensured between the hangers 17 adjacent to each other in the workpiece loading section 3, and the work of attaching the sewing workpiece to the gripping section 19 of the hanger 17 can be easily performed. .

Hangers 17 arranged in the workpiece loading section 3
are sequentially transferred to each station 4 provided corresponding to each processing table 1. The peripheral mechanism of each station 4 will be explained based on FIG. 7. At each station 4, the rail 2 is provided with a downward slope section 26 and an upward slope section 27 so as to be continuous. An operation panel 28 is installed on the ceiling frame 16 corresponding to the descending slope 26, and a locking mechanism is provided at the lower end of the control panel 28 for locking the rotating body 18 of the hanger 17 that moves on the downward slope 26 under its own weight. Stop member 29

The locking member 29 is rotated back and forth a predetermined number of times inputted by the input section 30 of the operation panel 28, so that a required number of hangers 17 are fed into the station 4. Then, on the processing table 1 corresponding to the station 4, the sewing workpiece of the hanger 17 is subjected to a predetermined processing such as sewing by a sewing machine.

Each station 4 is provided with a lifting mechanism including an air cylinder 31, a chain (not shown), and an engaging claw 32, and the hanger 17 is moved along the rising inclined portion 27 by engagement of the engaging claw 32 with the rotating body 18. After being lifted, it is transferred to the subsequent station 4 via the next descending ramp 26. A first micro switch 33 is attached to each station 4 to detect the presence or absence of a hanger 17, and a predetermined number of hangers 17 are installed on the starting end of each descending slope 26. A second microswitch 34 is provided to detect this and stop the feed from the station 4 in front. Reference numeral 35 shown in FIG. 7 is a regulating piece for preventing the hanger 17 from falling off from the rail 2 by regulating the inclination of the rotating body 18 by a predetermined angle or more.

On the other hand, as shown in FIG. 2, the guide mechanism of this embodiment for transferring each hanger 17 allows the hanger 17 to be moved between the front station 4 and the following station when the same processing is performed on a pair of adjacent processing tables 1. The station 4 is provided with a bypass path 36 for distributing and transferring the materials to the station 4. As shown in FIG. 7, each bypass 36 includes a fixed rod 37 whose base end is connected to the descending slope portion 26, and a swing rod rotatably connected to the tip of the fixed rod 37 via a shaft 38. 39
The swinging rod 39 is adapted to be driven up and down by an air cylinder 40. and,
When detouring the hanger 17, the swinging rod 39
is swung between a lower receiving position and an upper lifting position, and the lifted hanger 17 is rotated by the swinging rod 39 through the rolling of the rotating body 18 due to its own weight.
It is transferred along the fixed rod 37 and the downward slope 26 to the subsequent station 4. This bypass path 3
A third micro switch 4 that operates only when the bypass mode is set is provided in the descending slope portion 26 corresponding to 6.
1 is arranged to detect the last acceptable hanger 17 of the downward slope section 26 when the mode is set.

The hangers 17 that have passed through each station 4 and have been processed for the required number of man-hours are sequentially transferred to the workpiece unloading section 5 shown in FIGS. 2 and 3, where the sewing workpieces are removed from each hanger 17. The hanger 17 in a state where no work is supported is connected to the air cylinder 8 of the three-stage lifting mechanism 6 shown in FIG.
