Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a conveyance processing control device, and particularly to an assembly of workpieces flowing on a conveyor.

[Prior art] Conventionally, when assembling electrical products, clothing, bags, etc. by assembly line work, workpieces are assigned to each worker positioned along a conveyor, and the workers are assigned to workpieces flowing along the conveyor. After taking the parts out onto the workbench and assembling the parts for which one is in charge, the parts are again placed on the conveyor and flowed, and a finished product is obtained at the exit of the conveyor.

However, with conventional conveyance processing, the worker must take out the workpiece from the conveyor onto his or her own workbench, and then place the part on the conveyor again after completing the work. When the parts are large in size, this work of loading and unloading places a heavy burden on the workers.

Therefore, a processing station or a stage having a carry-in mechanism and a conveyance mechanism for carrying the workpieces flowing on the conveyor in and out toward the worker's processing section is arranged along the conveyor, and the above-mentioned carry-in mechanism and carry-out mechanism are controlled. By doing so, it is possible to automatically carry in and out the parts to be processed.

On the other hand, the loading/unloading mechanism described above can be configured using a motor and a belt conveyor, but when configured in this way, the weight increases, the mechanism cannot be easily transported, and the cost increases. Moreover, as the number of processing stations increases, the amount of power consumed by the motor increases.

[Summary of the invention]

An object of the present invention is to simplify the configuration of the loading/unloading mechanism by enabling a container for storing workpiece parts to be loaded into and unloaded from the processing section of the operator using the driving force of a cylinder device. The present invention will be described in detail.

[Embodiments of the invention]

1 to 5 are simplified configuration diagrams showing one embodiment of the conveyance processing control device according to the present invention, and in each figure, 1, 1,
2 is a conveyor for each outbound trip.

It is a return conveyor, extending in a straight line to each other,
A direction change conveyor 3 is arranged at one end thereof. As a result, the workpiece 5 carried in from the entrance 4A side of the conveyor 1
is from conveyor 1 to conveyor 3. It is carried out via the conveyor 2 from the outlet 4B. A plurality of processing stations 6 are arranged along the extension direction of each conveyor 1.2. As shown in FIGS. 2 to 5, each station 6 includes a carry-in path 9 which is inclined toward the operator 7 and has a plurality of rollers 8 arranged along the inclination direction, and this carry-in path 9.
It is composed of an unloading path 10 having rollers 8 and a processing section 11 located in parallel with the conveyance path 10 . In this case, the loading path 9. Export! 1
The length of 0 is set to such a length that containers 12 serving as containers for storing workpieces are positioned in two rows, and the previous container 12A sent to the worker 7 is stopped by a stopper (not shown). be done. The workpieces in the container 12A are taken out and processed in the processing section 11, and then stored in the container 12A again.
By pushing it out to the side, the area where the container 12A is located becomes blank, so the next container 12 will move to this position along the slope of the carry-in path 9 by its own weight. The container 12A is further pushed M by the operator to the exit of the carry-out path 10. When there is no container 12 on the entrance side of the loading path 90, the loading redetection switch T1 outputs a signal fl.
When a container exists on the exit side of the unloading path 10, the unloading redetection switch T2 outputs a signal f2. The carry-in path 9 has a container carry-in machine 13 as shown in FIGS. It is equipped with a cylinder 17 that drives the section 16 in the direction of the carry-in path 9 via an arm 17A, and a control panel 18 that controls this cylinder 17. Therefore, containers flowing on the conveyor 1.2 are blocked by the blocking plate 14. When the cylinder 17 is driven, it is pulled into the carry-in path 9 side by the take-in member 15, and moves in the direction of the worker 7 by its own weight. The carrying out machine 19 has a pushing frame 21A and a cylinder 21 which moves the pushing frame 21A in the direction of the conveyor 1.2 via an arm 20. , a guide poom 22, and a control panel 23 that controls the cylinder 21. As the cylinder 21 operates, the press crusher 21A moves in the direction of the conveyors 1 and 2, so the press frame 21A moves the container onto the conveyor. It is pressed in directions 1 and 2, placed on conveyors 1 and 2, and transported downstream.The control panels 18 and 23 are connected to the signal f.
an output signal gl from the control device 26 operating at l, f2;
Controlled by g2.

Note that lock pins 31.32 are provided at the front ends of the carry-in path 9 and the carry-out path 10, and these lock pins 31.32 are connected to lock holes 33 arranged along the sides of the conveyor 1.2.
The input path 9 and the output path 10 always form a pair of stations and are arranged along the conveyor 1.2. Each leg 34.3 of the loading path 9 and the loading path 10
5 is provided with rollers 36 and 37, thereby making it easily movable.

Here, the arrangement of each station 6 will be explained. As shown in FIG. 1, the number of stations 6B to be installed is set based on the processing time of station 6A, which has the shortest processing time among the stations 6, and the number of stations 6B, which has a longer processing time.

That is, if the processing time of station 6A is 3 minutes and the processing time of station 6B is 18 minutes, the number of stations 6B installed is six. As a result, all six stations 6B can process the processed parts of the container that was transferred from station 6A approximately three minutes ago, and there is no need to carry out unprocessed containers to the downstream side of station 6B. .

- For example, the processing section 11 is a sewing machine such as a sewing machine that sews together a plurality of cloth materials, leather materials, etc., and a welding machine that joins and fixes a plurality of metal parts and resin parts together.

There are screw fixing devices, etc. The worker takes out the workpiece 5 from the container, sews or joins the parts he/she is in charge of, carries out the part from the carry-out path 10 to the conveyor 1 or 2, and repeats the next similar operation. That is,
-This conveyance processing control device sequentially executes the work of one process necessary to manufacture one finished product.
The processed parts stored in the container come out from the outlet 4B as a finished product. A terminal section 241 consisting of control panels 18 and 23 and a work interrupt switch section 24 is connected to a control device 26 via a signal line 25. The control device 26 is composed of a central processing section 27, an input/output interface 28, and an operation section 29 consisting of a keyboard, etc.
6 controls each control panel 18, 23, displays necessary data on the display section 30, and further controls the motors that drive the conveyors 1, 2.3. The control device outputs a signal f of the unloading re-detection switch T2 when a container after processing is pressed against the outlet of the unloading path 10 of a predetermined stage gin 6 on the upstream side.
2, the cylinder 21 is
This operation is set and memorized in advance to push out the container.When a container is present at the entrance of the loading path 9 of a predetermined station on the downstream side and is empty, a signal is activated by the loading re-detection switch T1. Step 32) is performed when f1 is desired to be supplied. In this way, the station to which the container should be carried in with respect to the station from which it should be carried out is stored in advance in the memory. For example, as shown in FIG. 7, for station 6Al, 6B1, @
As shown in the figure, 6B2 is assigned to station 6A2.

Step 31. S2 is the case where the container is transported from the adjacent upstream station to the downstream station, but if the container is transported across stations as shown at @ in FIG. 7, steps 33 to S4 are further executed. do. In other words, it is determined whether or not the downstream station adjacent to the upstream station is already in a state to carry out the container, and if it is in a state where the container can be carried out, the above-mentioned carrying out on the upstream side is performed. Pause for a while (
Step 33). As shown in Fig. 7, when a container is carried out from station 6A1 to station 6B1 on the downstream side across station 6A2, when the container is carried out from station 6A2 to station 6B2, Q is carried out from station 6A1. This is because the container will collide with the container carried out from station 6A2. Therefore, even if the signal f2 is output from the station 6A1, the unloading operation from the station 6A1 is not performed, but after the unloading operation is performed from the station 6A2 (after a certain period of time has elapsed), this unloading operation is performed. In addition, when transporting a container from a predetermined station to an arbitrary downstream station by straddling an arbitrary station on the downstream side, after this downstream station carries in the container (step S4), the container is transferred from the straddling station to the downstream station. is transported. That is, as shown in Fig. 7 (■), from station 6A1 to station 6A
In the case of conveying a container to station 6B1 across 2, if the container is carried out from station 6A2 when station 6B1 carries the container in, station 6B1 carries in the container from station 6A2, and the container is transferred to the destination station. This is because it will not be carried into 6B2. Therefore, in this case, after the container from 6A1 is carried in to 681, the container is carried out from station 6A2. In addition,
When the work interruption switch section 24 is turned on, the signal f1
is cut, and the signal f1 is no longer output. For this reason, even if there is no container at the entrance of the entrance to the loading path of that station, it is assumed that there is a container and loading is prohibited. Even in this case, the control operation by the control device 26 based on the program shown in FIG. 6 is executed.

However, as shown in O in FIG. 7, the above program has a built-in program that when transporting a container from station 6A1 to station 6B3, for example, transports the container to station 6B4 when station 6B3 is prohibited. It is effective when Therefore, when the work at stations 6 and B3 is interrupted, the container is carried into station 6B4, which performs the same work, and the work can be carried out without any problem. Therefore, by storing such a program in the control device 26, it is possible to prevent the complexity of the control of changing the program when control is enabled and interrupted. Also, as shown in Fig. 7, an open space is provided after the latter station 686, and if it is necessary to move any station 6B5 to this open space, the program is set as if the station exists in this open space. Then, as shown in x and y, containers are carried in from stations 6A1 to 6B5 or vacant lot 6BT. In this case, by operating the keyboard of the operation unit 29, when the station 6B5 is not moved, carry-in in the X direction is selected, and when the station 6B5 is moved, carry-in in the X direction is selected. This allows station 6B5 to be replaced with vacant land 6 without changing the program.
You can move to B7 and perform similar tasks.

Next, as shown in Figure 8, the type l, which requires the most processing man-hours,
Type m requires less processing man-hours.

The type n that requires the least number of processing steps is placed on the same conveyor 1.2.
The case of multi-product processing will be explained below.

In this case, all varieties 1. Stations 6A to 6I capable of processing m and n shall be arranged, and the types!
Stations 6A, 6C, 6D, 6 to be processed
Station 6A to be processed for E, 6H, 61° variety m.

Selection patterns Pi, Pm, and Pn for selecting stations 6A, 60, 6F, and 6G to be processed for types 6C, 6B, 6G, 61, and type n are stored in advance in the storage section of the control device 26. As a result, station 6A is selected for type l based on the selection pattern Pffi in the storage section.

6C, 6D, '6E, 6H, and 61 are sequentially selected.

A predetermined station is also selected for the product type m according to the selection pattern Pm, and a predetermined station is also selected for the product type n according to the selection pattern Pn. In this case, variety j! If the conveyors 1 and 2 are conveyed in the order of .

For example, when a container is transported from station 6C, station 6D is selected for type l, station 6B is selected for type m, and station 6F is selected for type n. From station 6C, type 41. Containers will be transported in the order of m and n, but since station 6D is selected first, type l can be taken in with this, and then station 6-
Since station E is selected, type m can be loaded, and then station 6F is selected, so type n can be loaded. Here, the above selection pattern Pj! .

A selection means 40 (or the operation section 29 may be used) for manually selecting and specifying Pm and pH is provided, and the selection means 40 (or the operation section 29 may be used) is provided to manually select and specify Pm and pH every two days.

Selected pattern PI every month! By selecting and specifying any one of , Pm, and PnO, finished products of -type can be manufactured every hour, every two days, and every September.

The operation of the conveyance processing control device explained above will be explained below. When containers containing workpieces are sequentially carried in from the entrance 4A of the conveyor 1, the containers are carried into the stations 6 arranged in the order of processing steps, and when the processing is completed by the operator 7, the control device 26 outputs a signal g3. ,
The cylinder 21 is operated via the control panel 23 to transport the container containing the processed parts onto the conveyor 1. Next, a signal g2 is output to the station on the downstream side, the cylinder 17 is operated via the control panel 18, and the container is carried in. A program as shown in FIG. 6 is executed for carry-out and carry-in operations between each station. This prevents containers from colliding with each other and from pulling containers into the wrong station. In addition, you can freely interrupt work and move containers.
