Abstract

PURPOSE:To embody an optimum production line of good balance and enable efficient production by applying the constitution wherein each work stage is provided with a stopper control means for the preceding work stage and a stopper for the preceding work stage can be controlled in an after-work stage. CONSTITUTION:When a worker M3 operates control switches S31 and S32 for the preceding work stage stopper and releases the preceding work stage stoppers STP1 and STP2, pallets 1 and 2 as stopped at the preceding work stage are carried on a conveyor C to a machine for the worker M3. And stopper control switches S33 and S34 for the next work stage are operated and the pallets 1 and 2 are stopped with stoppers STP3 and STP4. Then, the pallets 1 and 2 are shifted on a transfer machine L2 to a work table T3, thereby enabling the execution of work. The pallets stagnating with stoppers for the preceding work stage due to a trouble and the like in that stage, therefore, can be transferred to the next work stage, and an optimum production line having a good line balance can be embodied, thereby ensuring efficient production.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a production line in which pallets carrying work objects are sequentially conveyed through each process on a conveyor, and a stopper for stopping the pallets on the conveyor; , relates to an improvement of a conveyor-type production line in which each process is provided with a transfer machine that transfers the stopped pallet to a workbench for each process.

[Conventional technology]

Conventionally, there is a loft production method that produces a large number of products at once in a batch method, but in this batch method,
Since it is difficult to uniformize the work process, a continuous production line as shown below is adopted.

In other words, the pallets carrying the semi-finished products being worked on are conveyed,
Each process proceeds sequentially, and in each process, the stopper of the own process is controlled to stop the desired pallet, the pallet is transferred from the conveyor to the workbench by the transfer machine, and the predetermined work is performed on the workbench. This is a production line in which the work is carried out, and after the work in the own process is completed, the transfer machine returns it to the conveyor and sends it to the next process.

[Problem to be solved]

However, in the above-mentioned production line, in the process of producing and arranging precision electronic equipment, etc., if the work in one process is delayed due to the number of measuring instruments or the occurrence of trouble, the work in the next process will be delayed. There is a problem in that the entire production line is delayed.

In order to avoid this problem, if the process is arranged with a margin, the problem arises that efficiency deteriorates.

[Means for solving problems]

In order to solve the above-mentioned problems, the conveyor type production system according to the present invention takes a measure of providing a front-process stopper control means in each process so that the stopper of the front-process can be controlled from the rear-process.

[For production]

That is, in the conveyor type production system according to the present invention, when the front process stopper control means provided in each process is operated from the downstream process to release the stopper of the previous process, the stopper of the previous process is stopped. The pallets are transported by a conveyor and sent to the next process.

〔Example〕

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the drawings.

The drawing is a plan view of a production line to which the conveyor-type production system according to the present invention is applied.

In the drawing, there are work tables T on both sides of the conveyor C that transports pallets L, ~, 16 on which semi-finished products are placed.
1, . . . , T8 are arranged, and the workers in charge M1. ~． M8 is installed and stopper STP 1
．． ~, 5TP8 stops a predetermined pallet on the conveyor C, and transfer machines Ll, ~, L4 transfer the pallet onto the work table on the side. Here, workers Ml, ~, M
4 and worker M5. ~． M8 is a process in which each of the four people performs the same work.

To explain normal work using worker M3 as an example, conveyor C
When a semi-finished product placed on a pallet during production is transported, worker M3 operates the own process stopper control switches S33 and 34 at hand to stop the pallet using stopper 5TP3.4, and then moves it to the next step. Operate the loading equipment controller S35 to move the pallet to your own workbench T3 and work on it.

After the work is completed, the transfer machine controller S35 is operated again to return the transfer machine to the conveyor C and stopper 5TP3.
．． 4 is released and the pallet is sent to the next process.

However, while worker M1 or M2 in the previous process is working on workbench T1 or workbench T2 while operating the stopper 5TP1.2 to stop the flow of pallets,
If a problem occurs and the work is delayed, the pallets 1 and 2 will remain stopped on the conveyor C by the stoppers 5TPI and 2, so the pallets 5. ~
, 8 is completed, worker M3. M4
This eliminates the work involved, leading to waste in the process.

Therefore, the operator M3 switches the front process stopper control switch 5
31. Operate 532, stopper 5TPI of the previous process,
When 5TP2 is released, the pallet 1.2 that was stopped in the previous process is carried by the conveyor C to the side of the worker M3, so the own process stopper control switch S3
3. Operate S34 to move pallet 1.2 to stopper 5T.
Stopped by P3゜5TP4 and transferred to workbench T3 by transfer machine L2.
This will allow you to move to and work on it.

In this way, the stopper in the previous process can be controlled by the previous process stopper control switch installed in the subsequent process, so pallets that were stuck at the stopper in the previous process due to problems in the previous process can be sent to the subsequent process. This makes it possible to realize an optimal production line with line balance.

〔effect〕

As described above, according to the conveyor-type production system according to the present invention, since a pre-process stopper control means is provided in each process, it is possible to prevent stagnation of the production line as described above, and to maintain the production line with optimal line balance. This has the effect of enabling efficient production.
