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 work by organizing each work process into a line, hangers holding sewn products have been moved sequentially on constructed rails that follow a series of work processes. Hanger-type transport devices have been widely adopted.

Therefore, this type of conventional hanger-type conveyor device is
For example, as shown in Fig. 4, a descending rail with a gentle slope on which the rollers of the hanger can roll and a rising rail with a steep slope are alternately connected and constructed in a straight line or in a loop. A stopper consisting of two stop cylinders 2, 5, etc., which operate alternately, is disposed at appropriate positions on the rail, and a lifting cylinder which operates up and down is disposed on the lifting rail along its entire length. The cylinders N, E, and H are electrically interlocked via a limit switch or the like that operates depending on the presence or absence of the hanger eye, so that the hanger eye is sequentially conveyed one by one.

However, in such a structure, the end of the descending rail, which is the stopping position of the hanger, is fixed, so if the hanger or the sewn article suspended thereon gets caught on an obstacle placed on the floor, the hanger may or depending on the length of the sewn item,
In addition to being soiled by sliding on the floor at the bottom, it is often impossible to work with the sewn item on the hanger, and workers have to remove the sewn item from the hanger each time and place it on the workbench. After the hanger was placed and processed by sewing, etc., 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 has been developed by arranging a large number of conveyor rails having a slope on which the hanger can roll in series such that the starting end of the next conveying rail is higher than each terminal end, so that each terminal end and starting end of the adjacent conveying rails are arranged in series. are connected to each other by a lifter, and a movable rail that goes up and down along the lifter is provided, a double stopper consisting of two stoppers is provided near the end of each of the above-mentioned transport rails, and one stopper is provided near the end of each movable rail. The above-mentioned problems were solved by providing two stoppers and interlocking the stoppers arranged on each rail through a sequencer or the like so that the hanger could be supplied at any desired height.

[Effect]

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.

Embodiment 1 In FIG. 1, 1, 1'... each have a gentle downward slope in the transport direction, and a large number of conveyor rails are installed intermittently at a certain height, and 2 is an interrupted part of the conveyor rails. an elevating rail mechanism installed in the transport rail 1, 1',
For example, movable rails 4 and 4' are attached to be movable up and down by lifters 3 and 3' consisting of rodless cylinders, and a work rail 5 having the same slope as the transport rail is constructed between the movable rails via a clamp C. , its position can be arbitrarily set according to the height of the workbench T, etc.

Also, 6 and 6' are so-called double stoppers provided near the ends of each of the above-mentioned transport rails 1 and 1' and the work rail 5, and equipped with two stop cylinders whose pistons operate alternately. ' is a stopper consisting of a single stop cylinder provided on each of the movable rails 4, 4', and each stopper is operated by a suitable sequencer (not shown) to engage the hanger. It can be stopped or released.

In the figure, 8, 8... are hangers, which are composed of a roller 8a that can freely roll on each of the above-mentioned rails, and an arm 8b that is loosely engaged with the axis of the roller 8a, and is provided at the tip of the arm 8b. It is possible to suspend sewing items etc. using appropriate metal fittings 8c (see Fig. 3), and furthermore, 9 is a hanger provided at the rear of the stopper 7, 7' attached to the movable rail as required. 8 shows the anti-backward claw.

Next, we will describe the operating procedure of the hanger-type conveyance device of the above example with respect to sewing work such as clothing. The robot runs on its own and is stopped by the double stopper 6 and becomes in a waiting state.

When the front stop cylinder 6a is actuated by an appropriate sequencer, its piston moves backward (increases in the figure), and the first hanger 8, which was locked to it, rises in advance and reaches the conveyor rail 1. Transfer to the movable rail 4 connected to the 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 6a is At the same time as protruding again, the cylinder 6
The piston b moves back to advance one of the leading hangers and protrudes again, keeping the following hangers in a locked state.

Note 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 or the like is activated to lower the movable rail 4, and when it is joined to the work rail 5, the piston of the stopper 7 retreats, and the hanger 8 rolls on the work rail 5 to move the work platform (T ) and is stopped by a stopper 6 on the work rail 5. In this way, the descending height and stop position of the hanger are set in advance in accordance with the height of the workbench, etc., so that a predetermined sewing operation can be performed without removing the sewing item from the hanger 8.

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

Embodiment 2 The conveyance device shown in FIG. 2 first attaches each of the above-mentioned conveyance rails 1, 1', 1'', etc. to a support rod P via a clamp C so that they can move up and down, and then attaches the conveyor rails 1, 1', 1'', etc. , a lifting rail mechanism 2 consisting of the above-mentioned lifter 3 and a movable rail 4 provided with a stopper 7 is installed, and a work table T is positioned below the lifting rail mechanism.

According to such a 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 work platform T, etc., so that the worker can sit down from beginning to end without removing the sewing item from the hanger 8. Similar to the device of the first embodiment, sewing work etc. can be performed while standing still.

Next, after the sewing work is completed, by operating a foot switch or the like, the movable rail 4 is raised to a position where it connects with the next transport rail 1' by the operation of the lifter 3, and at the same time, the piston of the stopper 7 is moved back. The hanger 8 is transferred to the transport rail. Thereupon, the empty movable rail 4 immediately descends to the previous transport rail 1 position and stops, waiting in preparation for the transfer of the next hanger 8.

It should be noted that, as in the first embodiment, the lowering, raising, and lowering of the movable rail 4 to its original position, as well as the operation of the stopper 7, are controlled by limit switches, sequencers, etc., which are arranged at each part and work together electrically. It is similar to

Thus, the elevating rail mechanism 2 of the first embodiment
Since a plurality of hangers 8 suspending the sewing material are suspended on the work rail 5, there is no waiting time and the sewing work can be carried out quickly.

Further, according to the elevating rail mechanism 2 of the second embodiment,
Compared to the rail mechanism of the first embodiment, installation of the work rail 5 and one lifter 3' can be omitted;
In addition to greatly reducing the space on the work line, since the transport rails 1 and 1' are movable up and down, by connecting both transport rails 1 and 1' with the movable rail 4 in between, unnecessary This eliminates the need to raise and lower the hanger at the work location.

Furthermore, in both the conveying apparatuses of the first and second embodiments, if a bypass rail B is separately installed in the middle of the lifter 3 and the movable rail can be connected to the rail, it is possible to transfer, for example, a sewn product. It is possible to change the work process depending on the type, and to distribute work that requires a long time to multiple workbenches as appropriate.

All of the above rails are made of steel, aluminum, etc. with a round, square, or T-shaped cross section, and are suspended from the ceiling with support rods P. The means for constructing the lifters 3, 3' is not limited to the rodless cylinder, and it goes without saying that the lifters 3, 3' can be changed to any other means such as a motor-driven chain or a screw type.

〔Effect of the invention〕

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

In addition, in the present invention, the movable rail can be freely stopped and operated at any position on the lifter using a sequencer, so for example, if the starting ends of separate conveyor rails are placed at different heights of the lifter, the work can be carried out easily. It is also possible to branch the route, giving more freedom in the design of the transport route, making it possible to provide a transport device that can be used in an extremely wide range of applications.
