Abstract

PURPOSE:To avoid jamming on a carry conveyor by carrying the products to be worked from the working station in the downstream through a reverse feed conveyor parallel with the carry conveyor to the work station in the upstream same with that in the downstream. CONSTITUTION:A reverse feed conveyor 11 arranged in parallel with a carry conveyor 1 is run in reverse direction by a motor. The products carried over the conveyor 1 are worked at the working stations 2l, 2M and upon jamming of products at the working station 2l in the downstream, the jamming products are mounted onto the conveyor 11 then said conveyor 11 is run in predetermined section through operation of controller 13 to carry the products to the working station 2l in the upstream having same function with said station 2l and stop. Since the work is assisted by feeding the products reversely through the conveyor 11, jamming of products is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a conveyance processing apparatus that sequentially assembles workpieces while conveying them by a conveyor, and in particular,
The present invention relates to a conveyance processing device that prevents workpieces from becoming jammed on a conveyor.゛ [Prior art] Generally, in order to manufacture sewn products such as shoes and bags,
As shown in Fig. 1, processing stations 2 such as sewing machines are arranged in the order of work steps along a conveyor 1 that travels in one direction, and the parts necessary to obtain one sewn product from the conveyor population 3 are stored. By sequentially inputting the completed packages, each processing station 2 sews the parts in the package that it is in charge of to obtain an assembled finished product. The finished product comes out from the conveyor exit 4 in a packaged state. That is, the processing stations 2 are arranged in the order of work steps along the traveling direction of the transport conveyor 1, and, for example, when forming the bag 5 shown in FIG. The first pocket 7 is sewn at processing station 2, and the second pocket 8 that covers this pocket 7 is sewn at processing station 2M.
, and attach the above first pocket 7 to this second pocket 8.
The same third pocket 9 is sewn at a downstream processing station 2) having the same function as the processing station 2J2.

In this way, in the conveyance processing apparatus according to the prior art, predetermined machining operations are sequentially performed by the processing stations 2 during the process of being conveyed to the downstream side by the conveyor l. If the flow of processed products at processing station 2 is congested, the processed products will not be smoothly transported to processing station 2 on the downstream side.
For this reason, it not only has the disadvantage that it takes a long time to complete all processing operations and obtain a finished product, but also
Furthermore, there is a drawback that machining operations may become impossible due to traffic jams.

[Summary of the invention]

The present invention has been made in view of the drawbacks of the prior art.
A reverse conveyor that runs in the opposite direction to the conveyor is arranged parallel to the conveyor, and from the downstream processing station to the same upstream processing station as the downstream processing station via this reverse conveyor. By making it possible to transport the processed products, there is provided a conveyance processing device that prevents congestion of the processed products on the conveyor.

C Examples of the invention] Examples of the invention will be described below with reference to FIGS. 3 and 4. Note that the same components as those in the prior art are given the same reference numerals, and the description thereof will be omitted.

In the figure, 11 is a reverse conveyor, and the reverse conveyor 11
is disposed above the conveyor 1 in parallel with the conveyor 1, and is driven by a drive motor M to run in a direction opposite to the conveyor 1 (in the direction of the arrow). here,
The drive motor M is started or stopped by a command from the motor drive section 12.

Reference numeral 13 denotes a controller provided at each processing station 2, and the controller 13 outputs a control signal to the motor drive unit 12. Here, the controller 13 is operated by an operator, and based on a control signal from the controller 13, the drive motor M causes the reverse conveyor 11 to travel in an arbitrary section.

Although the conveyance processing device according to the present invention is configured as described above,
Next, the operation will be described in the case where a first pocket, a second pocket, and a third pocket similar to the first pocket are sequentially sewn onto a bag as described in the prior art.

First, a first pocket is sewn onto the workpiece transported by the transport conveyor 1 at the processing station 2, as in the prior art. Thereafter, the second pocket is sewn at the processing station 2M as in the prior art.

At this time, it is assumed that there is a traffic jam of processed products at the processing station 2 on the downstream side where the third pocket is to be sewn.

However, in this case, according to the present invention, the worker places the workpieces that are jammed at the processing station 2 onto the reverse conveyor 11, and at the same time operates the controller 13 to reverse the process. The feed conveyor 11 is caused to run in a predetermined section. Then, the processed product is transferred to the processing station 2.
It is conveyed to processing station 2 on the upstream side, which has the same function as No. 2, and stops there. Thereafter, the operator sews the third pocket at the upstream processing station 2L.

Thus, in the present invention, when there is a traffic jam of workpieces at a given processing station 2, the workpiece is transported to another upstream processing station 2 with the same function by the reverse conveyor 11 and the work is carried out. This helps prevent congestion of processed products. In addition,
The reverse conveyor 11 may be provided below the transport conveyor 1.

Further, the controller 13 may be automatically controlled by a control means.

〔Effect of the invention〕

As explained above, according to the present invention, a reverse conveyor is arranged parallel to the conveyor and runs in the opposite direction to the conveyor, and the downstream processing station is processed from the downstream processing station via this reverse conveyor. Since processed products can be transported to the same upstream processing station as the station, congestion of processed products can be prevented and smooth processing operations can be expected. −
