Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a sewn article that is suspended via a hanger on a conveyor rail arranged in a loop shape, for example, in a production line workshop such as a garment sewing factory. The present invention relates to an improvement of a hanger-type conveying device that sequentially moves the hanger to the next work location, and in particular, the height of the stop position of the hanger at the work location can be set arbitrarily.

[Conventional technology and its problems]

Traditionally, in clothing sewing factories, etc., in order to rationalize the work by organizing each work process into a line, hangers holding sewn items have been moved sequentially on an erected rail that follows a series of work processes. Hanger-type conveying devices are being widely explored.

As shown in FIG. 4, the conventional hanger-type conveying device of this type has a descending rail (b) with a gentle slope on which the hanger can roll, and a descending rail (b) with a steep slope. A stopper consisting of two stop cylinders which are installed in a straight line or in a loop by alternately connecting the ascending rails (c) of the above, and actuated alternately at appropriate positions of the descending rails (b), etc. On the other hand, the lift rail (C) has a structure in which a lifting cylinder (H) that moves up and down along its entire length is arranged, and a limit switch (T) that operates depending on the presence or absence of the hanger (I) is installed on the lift rail (C). ) to each of the above cylinders through electrically interlocking the hanger l.
(b) were conveyed sequentially to - pieces.

However, in such a structure, the terminal end of the descending rail, which is the stop position of the hanger, is fixed, so the hanger or the sewn article suspended thereon may get caught on an obstacle placed on the floor, causing the hanger to move automatically. Depending on the length of the sewing item, the lower part of the sewing item may slide against the floor and become dirty, and it is often impossible to work with the sewing item on a hanger, and the worker may Each time, remove the sewing item from the hanger and place it on the workbench. After placing the product in place and performing processing such as sewing, it had to be attached to the hanger again, which required a great deal of effort to attach and detach, which significantly reduced the efficiency of this series of operations. It is something.

[Means for solving problems]

In view of these circumstances, the present invention provides a plurality of transport rails with a slope on which the hanger can roll, and a lifting rail that can be raised and lowered via a lifter or the like at the interrupted portion of each transport rail. A mechanism is interposed between the movable rails and the movable rails are configured so that they can be connected to the respective conveyance rails, while stoppers arranged on each of the rails are interlocked via a sequencer or the like to supply the hangers at an arbitrary height. In this way, all the problems mentioned above are solved.

[For production]

The conveyance device of the present invention has the effect of being able to feed the sewn product suspended from the hanger at any time at a height appropriate for each working position.

〔Example〕

Hereinafter, the structure of the hanger type conveyance device of the present invention will be specifically described according to two embodiments.

(Example 1) In FIG. 1, 1-1', 1'... each have a gentle downward slope in the transport direction, and are constructed intermittently at a certain height, a large number of transport rails; is an elevating rail mechanism installed at the interrupted part of the conveyance rail, and the movable rail 4.
4° so that it can be raised and lowered freely, and clamped between the movable rails [
A work rail 5 having the same slope as the conveyance rail is installed via the work rail 5, and its position can be arbitrarily set according to the height of the work platform (1), etc.

Further, 6 and 6'' are so-called double stoppers provided on each of the above-mentioned conveyance rails and near the end of the work rail 5, and are equipped with two stop cylinders whose pistons operate alternately, and 7 and 7'' are respectively The stopper consists of a single stop cylinder provided on the movable rails 4, 4, and each stopper has its piston actuated via an appropriate sequencer (not shown) to lock the hanger. Or it can be released.

In the figure, 8, 8, . . . are hangers, which are composed of a roller 8a that can freely roll on the above-mentioned rails, and an arm 8b that is loosely connected to the axis of the roller 8a. Sewn items, etc. can be suspended using appropriate metal fittings 8c provided (see Fig. 3), and furthermore, 9 is provided behind the stoppers 7, 7゛ attached to the movable rail as required. The claws for preventing the hanger 8 from moving backwards are shown.

Next, we will describe the operation procedure of the hanger-type transport device for upper peeling when sewing clothes, etc. In Fig. 1, the sewn product that has been finished in the previous process is suspended by the hanger 8 and placed on the transport rail 1. The robot runs on its own and is stopped by the double stopper 6, and enters a waiting state.

When the front stop cylinder 68 is actuated by an appropriate sequencer, its piston moves backward (increases in the figure), and the first hanger 8 that is locked to it moves back.
is moved up in advance and transferred to the movable rail 4 which is connected to the transport rail 1. In this case, the other hangers 8 lined up in a waiting state on the transport rail 1 are locked because the piston of the rear stop cylinder 6b is still protruding, but the piston of the front stop cylinder 68 is protruding again. At the same time, the piston of the cylinder 6b retreats to advance the leading hanger and project it again, keeping the trailing hangers locked.

It should be noted that the hanger 8 is locked on the movable rail 4 between the piston of the stopper 7 and the claw 9 to reliably prevent it from falling.

Next, a limit switch etc. is activated and the movable rail 4 is
descends, and when joined to the work rail 5, the piston of the stopper 7 retreats, and the hanger 8 rolls on the work rail 5 until it reaches the vicinity of the work platform (1) and stops at the stopper 6 on the work rail 5. It is locked by. In this way, the descending height and stop position of the hanger are set in advance according to the height of the workbench, etc., so that the sewing work can be performed without removing the sewing item from the hanger 8 (predetermined sewing work can be performed).

After the work at this location is completed, when the piston of the stopper 6 is moved back by operating a foot switch (not shown), the hanger 8 is moved back to the movable rail that has been joined to the end edge of the hanger 8 in advance. At this point, the movable rail 4° is raised by the operation of a limit switch or the like, joins with the next transport rail 1°, and is sent to the next process.

(Embodiment 2) The conveying device shown in FIG. In the interrupted part of
A lifting rail mechanism 2 consisting of the above-described lifter 3 and a movable rail 4 provided with a stopper 7 is installed, and a workbench (1) is positioned below the lifting rail mechanism.

According to the lifting rail mechanism 2, the hanger 8 is transferred to the movable rail 4 according to the work procedure described above and then lowered to a position set in advance according to the height of the workbench (1), etc., so that the work can be carried out easily. Similar to the device of the first embodiment, the operator can perform sewing work while sitting all the time without removing the sewing item from the hanger 8.

Next, after the sewing work is completed, the movable rail 4 is raised to the position where it connects with the next conveyance rail 1° by operating the lifter 3 by operating the F7) switch, etc., and at the same time,
The piston of the stopper 7 moves back to transfer the hanger 8 to the transport rail. Thereupon, the empty movable rail 4 immediately descends to the previous transport rail 1 position and stops, waiting for the transfer of the next hanger 8.

Note that the lowering, raising, and lowering of the movable rail 4 to the original position, as well as the operation of the stopper 7, are controlled by limit switches, sequencers, etc., which are controlled by each part and electrically operate together, as in the first implementation. Similar to the example.

Since the elevating rail mechanism 2 of the first embodiment has a plurality of hangers 8 suspending the sewing material on the working rail 5, there is no waiting time.
Sewing work can be done quickly.

Furthermore, according to the lifting rail mechanism 2 of the second embodiment, the installation of the work rail 5 and one lifter 3° can be omitted compared to the rail mechanism of the first embodiment, so the space of the work line is significantly reduced. In addition, since the transport rail 1' is movable up and down, by connecting both transport rails 1' with the movable rail 4 in between, it is possible to omit lifting and lowering of hangers at unnecessary work locations. It is.

Furthermore, in both the conveying devices of the first and second embodiments of the present invention, a separate bypass rail (formerly) is installed in the middle of the lifter 3,
If the movable rail can be connected to the rail,
For example, it is possible to change the work process depending on the type of sewing item, or to distribute work that requires a long time to multiple workbenches as appropriate.

It should be noted that each of the above-mentioned rails is made of steel, aluminum, etc. with a round, square or T-shaped cross section, and the support rod [Pl
The above-mentioned lifter 3.3 is not limited to the above-mentioned mouth/nodless cylinder, but may be installed by a motor-driven means such as using supporting legs. Chain, screw one type, etc.
Needless to say, it can be changed by any means.

〔Effect of the invention〕

As described above, the hanger-type conveyance device of the present invention has the conveyance rail mounted at a high location, and the lift rail mechanism 2 allows the hanger 8 to be supplied at any height considering the workability. Because of this, it is possible to completely omit the cumbersome chores such as attaching and detaching sewn items from hangers and removing obstacles that obstruct the hanger's self-propulsion, which previously required time and effort, and can significantly improve work efficiency. In addition, various effects can be expected, such as being able to reliably prevent staining of sewn items due to rubbing during transportation, etc.
