Description

  The present invention relates to an automatic processing system including a production machine and an automatic robot in an automated production process.

  Conventionally, in a production line in which a plurality of processes are automated, such as a press line for manufacturing a finished product or an intermediate product, a plurality of press machines arranged in a row as shown in FIG. Automatic robots that move workpieces and place them on a press machine were installed at both ends.

Hereinafter, a conventional example will be described in detail. Reference numeral 100 denotes an automatic processing system. The automatic processing system 100 includes a plurality of press machines 101 and a plurality of automatic robots 102 and 103, and forms a press line. The automatic processing system 100 includes a belt conveyor on which a workpiece supply device 104 that supplies a material to the first press process is placed adjacent to the front stage of the system 100 and conveys a press product completed in the final press process. A conveying means 105 is placed adjacent to the rear stage of the system 100.
In this conventional example, the automatic processing system 100 has four press machines 101a to 101d arranged in a row, the press machine 101a performs the first pressing process, and then press machine 101b, press machine 101c, press machine The press process in the respective press machines 101 is sequentially completed with the machine 101d, and a finished product or an intermediate product by the automatic machining system 100 is manufactured by press work in the press machine 101d.

The automatic robot 102 is a robot that moves a workpiece W, which is an intermediate product pressed by the press machines 101a to 101d, between the press machines 101a to 101d, between the adjacent press machines 101a to 101d. , 101b, an automatic robot 102a installed between the press machines 101b and 101c, and an automatic robot 102c installed between the press machines 101c and 101d.
The robot 103 includes an automatic robot 103a and an automatic robot 103b. The automatic robot 103a is a robot that supplies a workpiece W to a press machine 101a that is the first step of the automatic machining system 100, and is a workpiece supply device that is installed adjacent to the system 100 and supplies a material that is the source of the workpiece W. The workpiece W is taken from 104 and placed on the press machine 101a so as to be capable of being pressed. The automatic robot 103b is installed between the press machine 101d that performs the final pressing process and the transport unit 105, takes out the workpiece W from the press machine 101d, places it on the transport unit 105, and transports it to the transport unit 105.

In the automatic machining system 100 configured as described above, when the work W is completed by performing the press work of the press machines 101 a to 101 d four times, the robot 103 a takes out the unprocessed work W from the work supply device 104. The press machine 101a is placed so as to be capable of being pressed. Next, when the press processing step is completed in the press machine 101a, the automatic robot 102a takes out the work W that has been processed from the press machine 101a and places the work W on the press machine 101b adjacent to the press machine 101a so that the press process can be performed.
When the press machine 101b finishes the press work, the automatic robot 102b takes the press-worked workpiece W from the press machine 101b and places it on the press machine 101c adjacent to the press machine 101b so that the press work can be performed.

When the press processing is completed in the press machine 101c, the automatic robot 102c takes out the pressed workpiece W from the press machine 101c and places it on the press machine 101d adjacent to the press machine 101c so that the press process is possible. When the press processing by the press machine 101d is completed, the processing of the workpiece W in the automatic processing system 100 is completed.
Next, when the press processing is completed in the press machine 101d, the automatic robot 103b takes out the press-processed work W from the press machine 101d, and places the completed work W on the transfer means 105 adjacent to the press machine 101d so that it can be transferred. .

  As described above, in the four-step press working by the press machines 101a to 101d, the four press machines can be sequentially used without being left over.

In general, the press working performed in a factory is not necessarily four steps, and three steps, two steps, or even one step is also performed. And in the factory, it is better to use the above-described conventional automatic processing system 100 without forming an automatic processing system corresponding to the number of steps in press processing that requires the number of steps of three or less. This is advantageous from the standpoint of securing the facilities and expanding facilities.
However, when the case where the conventional automatic machining system 100 is used to perform a press process consisting of two steps, as shown in FIG. 7, any two of the press machines 101a to 101d, for example, the press machines 101a and 101b are installed. The press machine 101c and the press machine 101d may be used without using the press machine 101c and the press machine 101d. Therefore, there are problems in that the two press machines 101c and 101d are idle and inefficient. did. In addition, although the number of steps is small, the automatic robot 102 has to operate in order to allow the press machine 101c and the press machine 101d to pass therethrough.

  Similarly, even in an automatic process consisting of three processes or one process, one or three press machines are not used and are in a idle state, resulting in a more inefficient operation. In this case as well, since the automatic robot 102 always moves the workpiece W sequentially, all the automatic robots 102 must be in operation, which is an inefficient automatic process.

  Therefore, an object of the present invention is to provide an automatic machining system capable of operating efficiently in an automatic machining system that processes a plurality of processes continuously.

This invention
Multiple automatic processing machines are installed side by side, and automatic robots that can move workpieces between adjacent automatic processing machines are installed between the parallel automatic processing machines. In a viable automatic machining system,
Two automatic robots installed between adjacent processing machines are installed between the processing machines located in the middle, one moves a workpiece between adjacent processing machines, and the other automatic robot carries out from the processing machine. An automatic machining system characterized by being able to carry out workpieces between two installed processing machines as an automatic robot,

  I will provide a. Therefore, in the present invention, when a series of manufacturing processes is performed using all the processing machines, the workpiece is sequentially processed from the processing machine located at one end, and the processing machine adjacent to the processing machine The workpiece is moved sequentially in the forward direction by an automatic robot for moving between machines, and the machining process in each machine is repeated, and the workpiece is processed by the machine located at the other end. Finish a series of processing and unload.

In addition, when a series of processing steps are completed without using all the processing machines arranged side by side, the workpieces are processed from the processing machines located at both ends of the processing machines arranged side by side, respectively, on the opposite sides. The workpiece is moved to an adjacent processing machine by an automatic robot and the processing is repeated simultaneously.
That is, the processing is performed sequentially from the processing machine located at one end among the processing machines arranged in parallel, and the processing is repeated in the forward direction to the adjacent processing machine by an automatic robot installed between the processing machine and the adjacent processing machine, From the processing machine that has completed the required processing to the workpiece, between the processing machine adjacent to the previous process of the processing machine or the processing machine adjacent to the subsequent process, which is the position for unloading the finished workpiece. The workpiece is unloaded from the installation by an unloading automatic robot installed in the machine.

In the above-mentioned processing from one end to the forward direction, a series of processing is completed up to the processing machine located in the middle, so the processing from the reverse direction is sequentially performed in the reverse direction from the processing machine located at the other end Performs machining, repeats machining in the reverse direction to the adjacent processing machine by the automatic robot installed between the processing machine and adjacent processing machines, and installs an unloading automatic robot that is not used in the forward direction Unload the workpiece from the position.
Thereby, the workpiece is processed from both the forward and reverse directions.

  Below, if you give an example of multiple machines in parallel,

Four automatic processing machines are arranged side by side, and an automatic robot that can move a workpiece between adjacent automatic processing machines is installed between the automatic processing machines arranged side by side. In an automatic machining system capable of performing 4 processes,
An automatic robot installed between adjacent processing machines, an automatic robot for moving the workpiece between adjacent processing machines, and an automatic robot for carrying out the workpiece from between the processing machines An automatic processing system characterized in that the workpiece can be carried out between each automatic processing machine,

  And Thus, in the automatic processing system using four processing machines arranged side by side, in the processing of a workpiece that requires four steps, the first automatic processing machine first performs the processing steps as described above. Next, an automatic robot installed between the first automatic processing machine and the second automatic processing machine moves the processed workpiece from the first automatic processing machine to the second automatic processing machine. And in the 2nd automatic processing machine, the moved workpiece is processed. When processing is completed in the second automatic processing machine, an automatic robot installed between the second automatic processing machine and the third automatic processing machine moves the workpiece from the second automatic processing machine to the third automatic processing machine. Next, the workpiece is also processed by the third automatic processing machine. When the process by the third automatic processing machine is finished, the workpiece is moved to the fourth automatic processing machine by the automatic robot installed between the third automatic processing machine and the fourth automatic processing machine as described above, and the fourth processing machine Apply final processing. Thus, when processing of a workpiece consists of four steps, it is performed by repeating the processing in the forward direction.

  Further, when the processing steps for processing the workpiece are completed without using all the first to fourth automatic processing machines, the first automatic processing machine and the fourth automatic processing located at both ends. The workpieces are machined from each of the machines, and the workpieces are moved to the machining machines adjacent to the opposite sides by the automatic robot, and the machining is repeated simultaneously.

That is, when processing a workpiece in three steps, the same processing as described above is performed in the forward direction by the first automatic processing machine to the third automatic processing machine, and from the second automatic processing machine to the third automatic processing machine. The workpiece is moved by an automatic robot for moving the workpiece installed between the second automatic machine and the third automatic machine. When the machining by the third machine is finished, the second automatic machine and the third automatic machine are moved. The workpiece is unloaded by an unloading automatic robot installed between the processing machines.
In this case, since the 4th automatic processing machine remains without performing the processing process, the workpiece to be processed in one process is processed by the 4th automatic processing machine, and the 3rd automatic processing machine and the 4th automatic processing machine are processed. Unloading is carried out between the third automatic processing machine and the fourth automatic processing machine by an unloading automatic robot installed between the processing machines.
In this example, the workpieces in the forward direction and the reverse direction are arranged between the second processing machine and the third processing machine, and between the third processing machine and the fourth processing machine so that they become different unloading lines after finishing the processing. , But may be carried out from the same carry-out line. In this case, the third machining is performed by an unloading automatic robot and a moving automatic robot provided between the third machining machine and the fourth machining machine. Unload from between the machine and the fourth processing machine.
Then, whether the workpieces in the forward direction and the backward direction are conveyed from the same unloading line or unloaded from different unloading lines frequently causes the possibility that the final process of both the workpieces is performed simultaneously. If so, it is possible to select appropriately such as unloading from different unloading lines and unloading from the same unloading line when there is no overlap.

When the workpiece is finished in two steps, the workpiece is moved between the processing machines in the same manner as described above in the forward direction from the first automatic processing machine and in the reverse direction from both sides of the fourth processing machine. Move by an automatic robot and repeat.
And when the process by the 2nd automatic processing machine is complete | finished, between the 2nd automatic processing machine and the 3rd automatic processing machine by the automatic robot for carrying out installed between the 2nd automatic processing machine and the 3rd automatic processing machine The workpiece to be processed after the two steps is unloaded.

On the other hand, in processing in the reverse direction, when processing of the workpiece is completed by the third automatic processing machine, the third automatic processing is performed by an unloading automatic robot installed between the third automatic processing machine and the fourth automatic processing machine. The workpiece having been processed in two steps is unloaded from between the machine and the fourth automatic processing machine.
In this example, the workpieces in the forward direction and the reverse direction are arranged between the second processing machine and the third processing machine, and between the third processing machine and the fourth processing machine so that they become different unloading lines after finishing the processing. , But may be carried out from the same unloading line. In this case, the second processing is performed by the unloading automatic robot and the moving automatic robot provided between the second processing machine and the third processing machine. Unload from between the machine and the third processing machine.
Then, whether the workpieces in the forward direction and the backward direction are conveyed from the same unloading line or unloaded from different unloading lines frequently causes the possibility that the final process of both the workpieces is performed simultaneously. If so, it is possible to select appropriately such as unloading from different unloading lines and unloading from the same unloading line when there is no overlap.

Furthermore, in the case of a workpiece that is finished in two steps, the workpiece in one step can be processed from the opposite direction. Therefore, the two-step machining operation and the one-step machining operation can be performed simultaneously.
In this case, the same action as the above two steps is performed in the forward direction, and in the reverse direction in which the machining operation is completed in one step, the workpiece to be processed in one step is processed by the fourth automatic processing machine. It is carried out between the third automatic processing machine and the fourth automatic processing machine by an unloading automatic robot installed between the three automatic processing machines and the fourth automatic processing machine.

Therefore, according to the automatic machining system of the present invention, it is possible not only to process by a process using all the processing machines in which workpieces are arranged side by side, but also when processing by a process less than that. Can be processed in the forward direction and the reverse direction. In addition, the number of processing steps is not the same, and processing with different numbers of processing steps is possible, so that the manufacturing time required for product processing can be reduced, and work using the processing machine can be performed efficiently.
Furthermore, since the production from the forward direction and the reverse direction can be performed independently, the machining can be performed without being affected. In particular, when the workpiece unloading lines from the forward direction and the backward direction are made different, there is an effect that even if the workpiece unloading timing overlaps, the workpiece can be completely independent.

The automatic processing system has four automatic processing machines arranged side by side. A workpiece supply device that supplies a workpiece is installed adjacent to the first automatic processing machine. In addition, an automatic robot for supply for moving the workpiece from the workpiece supply device to the first automatic processing machine is installed.
Similarly, a conveying means for carrying out the workpiece from the fourth automatic machine is installed adjacent to the fourth automatic machine. Also, an unloading automatic robot for moving the workpiece from the fourth automatic processing machine to the conveying means is installed.
In addition, an automatic robot for moving the workpiece between the processing machines and an automatic robot for unloading the workpiece from between the processing machines are installed between the adjacent processing machines. The workpiece can be moved between the machines and the workpiece can be carried out between the machines.
Then, the work piece is moved between the second automatic processing machine and the third automatic processing machine provided with the unloading automatic robot and between the third automatic processing machine and the fourth automatic processing machine by the unloading automatic robot. Is provided with an intermediate conveying means capable of unloading.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory plan view showing the present invention, and FIGS. 2 to 5 are explanatory views for explaining the operation of the present invention.

  Reference numeral 1 denotes an automatic machining system according to the present invention. The automatic machining system 1 is a system in which, in the automatic machining system 1, a plurality of unprocessed workpieces W that are workpieces are sequentially pressed by a press machine 11 provided. In the automatic machining system 1, a plurality of press machines 11a to 11d, which are a plurality of press machines 11, are installed, the forward direction in which the press work is sequentially performed from the press machine 11a to the press machine 11d side, and the press machine 11d to the press machine. The press work can be performed from the reverse forward direction in which the press work is sequentially performed toward the 11a side.

Reference numeral 2 denotes a workpiece supply device for supplying the workpiece W to the automatic machining system 1. The workpiece supply device 2 is installed adjacent to the press machine 11a so that the workpiece W to be pressed can be supplied to the press machine 11 of the automatic machining system 1.
Reference numeral 3 denotes an automatic robot for supply. The automatic robot 3 for supply is installed between the press machine 11a and the workpiece supply device 2, and can take out the workpiece W from the workpiece supply device 2 and supply it to the press machine 11a.

4 is a belt conveyor which is a conveyance means. The belt conveyor 4 is installed adjacent to the press machine 11d of the automatic processing system 1.
Reference numeral 5 denotes a reverse-direction workpiece supply device, which is a device that supplies the workpiece W when the automatic machining system 1 sequentially performs pressing operations from the reverse direction, and is installed adjacent to the press machine 11d.
Reference numeral 6 denotes an unloading automatic robot that unloads the workpiece W and a general-purpose automatic robot that functions as a supply robot that supplies the workpiece. The general-purpose automatic robot 6 is installed adjacent to the press machine 11d, the belt conveyor 4 and the reverse direction workpiece supply device 5 and can carry out the workpiece W which has been pressed by the press machine 11d to the belt conveyor 4. When the automatic machining system 1 sequentially performs pressing operations from the reverse direction, the workpiece W can be taken out from the reverse direction workpiece supply device 5 and supplied to the press machine 11d.

  7 and 8 are intermediate conveyors. The intermediate conveyor 7 is a carry-out means and is a belt conveyor. And the intermediate conveyor 7 is a means for conveying the workpiece | work W which was installed between the press machine 11b and the press machine 11c, and finished press work with the press machine 11b or the press machine 11c. Similarly, the intermediate conveyor 8 is also composed of a belt conveyor as an unloading means, and is installed between the press machine 11c and the press machine 11d, and is used for transporting the workpiece W that has been pressed by the press machine 11c or the press machine 11d. Means.

  The automatic machining system 1 is provided with a plurality of moving automatic robots 12 and an unloading automatic robot 13. The moving automatic robot 12 is an automatic robot that moves the workpiece W that has been pressed by the press machine 11 to the adjacent press machine 11, and is installed between the press machines 11 of the press machines 11a to 11d. In addition, the unloading automatic robot 13 transfers the workpiece W that has been pressed from the press machine 11 between the press machine 11b and the press machine 11c and between the press machine 11c and the press machine 11d. Can be taken out.

  Specifically, an automatic robot for movement 12a is installed between the press machine 11a and the press machine 11b, an automatic robot for movement 12b is installed between the press machine 11b and the press machine 11c, and an automatic robot for unloading 13a is installed. Between the press machine 11c and the press machine 11d, an automatic robot 12c for movement is installed and an automatic robot 13b for carrying out is installed.

  In this way, by installing the press 11, the moving robot 12 and the unloading robot 13 a in the automatic processing system 1, in each pressing operation that flows in the forward direction, the automatic robot 3 for feeding is supplied from the workpiece feeding device 2 to the workpiece. W is taken out and moved to the position of the press machine 11a and placed on the press machine 11a. In the automatic machining system 1, when each press machine 11 finishes the press work, a moving automatic robot installed between the press machines 11 in sequence. 12 moves the workpiece W to the adjacent press machine 11 and places it thereon, so that the press machine 11a sequentially presses the workpiece W, and finally the general-purpose automatic robot 6 from the press machine 11d to the belt conveyor 4 completes the workpiece W. Can be carried out.

Below, the press work in the forward direction and reverse direction which the automatic processing system 1 performs is demonstrated.
FIG. 2 is a flowchart illustrating the case where the workpiece W is processed in the four press processes in which the four press machines 11a to 11d perform press processing in the forward direction.

In the press 4 process shown in FIG. 2, the supply automatic robot 3 takes out the work W from the work supply device 2 and places it on the press machine 11 a that performs the first press process. Since the work W removal is always performed in the forward flow, only the work W is placed on the press 11a will be described below.
The press machine 11a performs the press process, and when the press process is completed, the moving automatic robot 12a takes out the work W after the press process from the press machine 11a and places it on the adjacent press machine 11b. In the press machine 11b on which the workpiece W is placed, the workpiece W is pressed. When the press machine 11b finishes pressing, the moving automatic robot 12b takes out the work W from the press machine 11b and places the taken work W on the adjacent press machine 11c. In the press machine 11c on which the workpiece W is placed, the workpiece W is pressed. When the press machine 11c finishes the press work, the moving automatic robot 12c takes out the work W from the press machine 11c, and places the taken work W on the adjacent press machine 11d. In the press machine 11d on which the workpiece W is placed, the workpiece W is pressed. When the press machine 11d finishes the press work, the general-purpose automatic robot 6 takes out the workpiece W from the press machine 11d and places the taken workpiece W on the adjacent belt conveyor 4. The belt conveyor 4 conveys the mounted workpiece W.

  As described above, when the pressing process is composed of four processes, the four press machines 11a to 11d are used, and the work W is sequentially flowed in the forward direction to be finished.

Next, the case where the processing in the forward direction and the processing in the reverse direction can be performed, which is a feature of the automatic processing system 1, will be described.
The example shown in FIG. 3 is a case where a workpiece W that can be completed by three-step pressing is performed. In this case, since one press 11 is unused, the unused pressing This is an explanation of a case where the workpiece W that can be completed by pressing in one step from the opposite direction using 11d can be combined. This will be described below as Example 2.

  First, in the forward direction, the supply automatic robot 3 places the workpiece W on the press machine 11a, as in the first example. In the automatic machining system 1, the same press work as in Example 1 is performed by the press machine 11a to the press machine 11c and the movement automatic robot 12a to the movement automatic robot 12b. Since the workpiece W exists in the press machine 11c at the time when the press work is completed, and the workpiece W has already completed all three steps, in Example 2, the workpiece W is carried out instead of the mobile robot 12c of Example 1. The automatic robot 13a takes out the workpiece W from the press machine 11c. Then, the unloading automatic robot 13a places the taken work W on the intermediate conveyor 8 installed between the press machine 11c and the press machine 11d. The intermediate conveyor 8 conveys the placed work W.

At the same time as the forward operation, the work W is pressed from the reverse direction in one step.
That is, the general-purpose automatic robot 6 takes out the workpiece W from the reverse direction workpiece supply device 5 installed adjacent to the press machine 11d and places it on the press machine 11d.
In the press machine 11d, the placed work W is pressed, and the press work in the press machine 11d is completed. Therefore, the unloading automatic robot 13b takes out the work W from the press machine 11d and places it on the intermediate conveyor 8. The intermediate conveyor 8 conveys the completed workpiece W.

As described above, in Example 2, the work W that has flowed in the forward direction is finished from the three-step press work and is carried out of the intermediate conveyor 8. Then, the workpiece W processed in the reverse direction is also unloaded from the intermediate conveyor 8 after completing the pressing process in one step. As described above, in Example 2, it is possible to simultaneously perform the pressing process in the three forward steps and the pressing process in the one backward direction.
In this example, it has been described that the workpieces W in the forward direction and the reverse direction are carried out from the intermediate conveyor 8, but may be carried out from different intermediate conveyors 7 and 8, respectively. The workpiece W finished by the press 11c is placed on the intermediate conveyor 7 by the unloading automatic robot 13a and unloaded, and the workpiece W processed in the reverse direction is loaded on the intermediate conveyor 8 by the unloading automatic robot 13b. What is necessary is just to convey.
Similarly, the workpiece W that has been processed in the forward direction is unloaded by the unloading automatic robot 13a or unloading automatic robot 13b so as to unload the workpiece W that has been processed in the forward direction from the belt conveyor 7 or the belt conveyor 8. W may be carried out from the belt conveyor 4 by the general-purpose automatic robot 6.
Further, in this embodiment, the forward direction and the reverse direction are described, and the respective workpieces W are described as flowing in the opposite direction. However, the workpieces W supplied from one side are processed by the press machine 11c in order from the press machine 11a and carried out. Unloading from the belt conveyor 7 by the automatic robot 13a and supplying the workpiece W supplied from the other side to the press machine 11d by the unloading automatic robot 13b from the belt conveyor 8 and unloading from the belt conveyor 4 by the general-purpose automatic robot 6 after the press processing is completed. You can make it.
Furthermore, a belt conveyor is newly installed in the vicinity of the workpiece supply device 2, the workpiece W to be supplied is conveyed by the belt conveyor 7 and the belt conveyor 8, and the workpiece W supplied from one side is pressed by the automatic robot 13a for carrying out. Is supplied to the machine 11d and continues to the press machine 11a in sequence, and after the machining by the press machine 11a is completed, it is unloaded from the belt conveyor newly provided by the supply automatic robot 3, and the workpiece W supplied from the other is the unloading automatic robot It may be supplied to the press machine 11d by 13b, and carried out from the belt conveyor 4 by the general-purpose automatic robot 6 after finishing the processing by the press machine 11d. In this way, by newly installing the belt conveyor, the workpiece W can be supplied from either, and can be carried out from either.
Note that according to the present invention, a method for supplying a plurality of workpieces W can be considered in the processing of each number of steps described below, but since it is the same as above, it will not be described in detail below.

  Next, Example 3 shown in FIG. 4 will be described. Example 3 is a case where the workpiece W that can be completed by two-step pressing is processed. In this case, since the two press machines 11 are not used in the pressing process in the forward direction, the same two processes or two different processes are performed in the reverse direction using the unused press machine 11. This is an explanation of the case where the work W that can be completed can be processed together.

  First, in the forward direction, the supply automatic robot 3 places the workpiece W on the press machine 11a, as in the first example. In the automatic processing system 1, the same press processing as in Example 1 is performed by the press machine 11a, the press machine 11b, and the moving automatic robot 12a. Since the work W exists in the press machine 11b at the time when the press work is completed, and the work W has already finished all the two steps, in Example 3, the automatic robot 12b for movement of Example 1 is used as the press machine. The workpiece W is taken out from 11b. Then, the moving automatic robot 12b places the taken workpiece W on the intermediate conveyor 7 installed between the press machine 11b and the press machine 11c. The intermediate conveyor 7 transports the placed work W.

At the same time as the forward operation, the work W is pressed in two steps from the reverse direction.
That is, the general-purpose automatic robot 6 takes out the workpiece W from the reverse direction workpiece supply device 5 installed adjacent to the press machine 11d and places it on the press machine 11d.
In the press machine 11d, the placed work W is pressed, and the press work in the press machine 11d is completed. Therefore, the moving automatic robot 12c takes out the work W from the press machine 11d and transfers the work W to the adjacent press machine 11c. W is placed. In the press machine 11c on which the workpiece W is placed, the workpiece W is pressed. When the press work of the work W in the press machine 11c is completed, the unloading automatic robot 13a takes out the work W from the press machine 11c and places it on the intermediate conveyor 7. The intermediate conveyor 7 on which the workpiece W is placed conveys the completed workpiece W.

As described above, in Example 3, the workpiece W that has flowed in the forward direction is finished from the two-step press work and is carried out of the intermediate conveyor 7. Then, the workpiece W that has been processed by flowing in the opposite direction and that has finished the two-step press processing is carried out from the intermediate conveyor 7. And in the press work of Example 3, the press work with respect to the workpiece W of the same type as the forward direction may be used. If the same type of workpiece W is pressed in both the forward and reverse directions, the press processing of all workpieces W can be completed in approximately half the time compared to conventional system operation. In the case of the workpiece W, two types of workpieces W can be simultaneously processed by one system.
In Example 2, the example in which the workpiece W in the forward direction and the workpiece W in the reverse direction are carried out from the same intermediate conveyor 7 is described, but in Example 3, the workpiece W that has been processed in the forward direction is moved to the automatic robot 12b for movement. May be placed on the intermediate conveyor 7 by the unloading automatic robot 13a and unloaded, and the workpiece W from the opposite direction may be unloaded from the intermediate conveyor 8 by the moving automatic robot 12c or the unloading automatic robot 13b.
Thus, also in Example 3, the supply of the workpiece W may be performed using the belt conveyor 7 and the belt conveyor 8 in addition to the workpiece supply device 2 and the reverse direction workpiece supply device 5 as in Example 2. The workpiece W is supplied from the workpiece supply device 2 and is unloaded from the belt conveyor 7 after the processing is completed. The workpiece W from the other side is supplied from the belt conveyor 8 or the reverse workpiece supply device 5 and is processed after the processing is completed. 4 or the belt conveyor 8 may be carried out. Furthermore, by newly installing a belt conveyor in the vicinity of the workpiece supply device 2, the workpiece W can be supplied from either as described in Example 2, and can be carried out from either.

Next, Example 4 shown in FIG. 5 is a case where two steps of pressing in the forward direction and one step of pressing from the reverse direction are performed simultaneously. In this case, the processing from the forward direction is shown in Example 3. Processing similar to the processing from the forward direction is performed, and processing from the reverse direction is performed in the same manner as the processing shown in Example 2.
In Example 4, as in Examples 2 and 3, the workpiece W can be supplied from either, and can be carried out from either.
