In case of the work to be worked at unmanned operation, the work carried into the carryin base 51 is stored in the empty place of the storage positions 401-421 of an automatic warehouse 30 until the unmanned operation is started. Then, it is decided as to whether or not all of the works to be worked at unmanned operation time are carried in and the unmanned operation is started.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic processing device for a workpiece using a machine tool.

<Conventional technology> As a system for automatically machining workpieces using machine tools,
A three-dimensional warehouse will be installed near the machine tool, and a temporary loading platform will be installed on the side of the machine tool to attach workpieces brought in from the outside to pallets, and a temporary loading platform will be installed to the side of the machine tool, and the space between the machine tool and the three-dimensional warehouse and loading platform will be installed. A guide rail is laid on the floor of the warehouse, and a transport vehicle is run sideways along this guide rail, and unprocessed workpieces are transported from the loading platform to the multi-storey warehouse using the forks installed on the transport vehicle, and are taken out from the multi-storey warehouse. A device is used that transports the machined workpiece into a machine tool, takes out the processed workpiece from the machine tool, and transports it to a three-dimensional warehouse.

<Problems to be Solved by the Invention> In the automatic processing equipment described above, in order to realize unmanned operation at night, a worker must store the workpieces to be processed during the unmanned time in a multi-storey warehouse during the day before starting unmanned operation. Store it. However, the workpieces stored in the multi-storey warehouse using transport vehicles are taken out and processed in the order in which they were stored, regardless of whether the workpieces are operated unmanned or manned. Therefore, for workpieces that require a long machining time, workpieces that do not require tool changes on the machine tool, and other workpieces that workers intentionally wish to machine when unattended, the workpieces to be machined during manned operation can be stored in a multi-storey warehouse. There was a problem in that it had to be stored in a multi-storey warehouse after being stored inside the building.

The present invention has been made to solve these problems, and an object of the present invention is to provide an automatic machining device that can perform manned machining on workpieces for unmanned machining.

<Means for Solving the Problems> The present invention has been made to achieve the above-mentioned object, and as shown in FIG. identification means 1 for providing identification as to whether the processing is to be carried out or when unattended;
A workpiece discriminating means 2 determines whether the workpiece is to be machined when manned or unmanned based on the identification of the identification means 1; A position storage means 3 stores the position where the workpiece determined to be processed is stored in the multi-level warehouse 30, and the workpiece stored at the storage position memorized by the position storage means 3 is stored when manned. It is equipped with processing execution means 4 for processing.

<Operation> The identification means 1 identifies whether the carried-in workpiece is to be machined when manned or unmanned, and the workpiece discrimination means 2 determines whether the workpiece is to be machined based on this identification. It is determined whether the object is to be machined when manned or unmanned, and the workpiece determined by this workpiece discrimination means 2 to be machined when manned is machined by machining another workpiece. When it is not possible to carry it into the machine, it is stored in the multi-level warehouse 30, and this storage position is stored by the position storage means 3. When machining of another workpiece is completed, the machining execution means 4 carries the workpiece stored at the position stored by the position storage means 3 into the machine tool and processes it.

<Example> Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, reference numeral 10 denotes a machining center as a machine tool, and a workpiece changing device 80 for placing a workpiece on the machine tool 10 is installed in front of the machining position. A three-dimensional warehouse 3 faces this machine tool 10.
0 is arranged, and a guide rail 40 as a transport device is arranged between the machine tool 10 and the multi-level warehouse 30, and a transport cart 41 is arranged on the rail of the guide rail 40 so as to be able to run horizontally. ing. Further, at one end of the guide rail 40, a carry-in table 51 for attaching the workpiece to the pallet (P) is arranged. A carry-in table operation panel 52 is attached to this carry-in table 5, and the carry-in table operation panel 52 determines whether the carried-in workpiece is to be processed normally during manned operation, Does it involve processing?
A loading mode selection button 53 for selecting whether machining is to be performed during unmanned operation, and an installation completion button 54 for informing a control device 60 (to be described later) that the workpiece has been placed in the parent position on the loading table 51. is installed.

Furthermore, the above-mentioned transport vehicle 41 is equipped with a fork for a corral, so that workpieces can be carried into the machine tool 10, the multi-level warehouse 30, and the carrying platform 51.

It should be noted that the multi-story warehouse 30 is divided into three floors, as shown in the front view in the direction of the arrow, and the respective storage positions are numbered 401 to 421.

60 is a control device for automatic processing equipment, mainly CFull
It is composed of a ROM 12 that stores a control program, and a RAM 13 that stores input data and the like. RAM13
A workpiece data storage area 131 is formed in which data on workpieces being carried into the three-dimensional warehouse 30 is stored.

CPU 1 connects machine tool 1 via interface 16
It is connected to the numerical control device No. 0, and a request signal for loading/unloading the workpiece in the machine tool 10 is input thereto. Furthermore, C
A carry-in/out request signal from the carry-in table 51 is input to Pt, +11 via the interface 16.

Further, the CPU II is connected to the control device of the transport vehicle 41 via the interface 17, and outputs a movement position command signal to the transport vehicle 41. Furthermore, an operation panel 22 is connected to the CPU 1 via an interface 18 .

The operation panel 22 also includes a keyboard 2 for inputting data.
3 and a CRT display device 21 for displaying data, an operation switching button 24 for switching the automatic processing device between unmanned operation and manned operation is also attached.

With the above configuration, the operation of the numerical control device 20 will be explained.

The flowchart shown in FIG. 3 shows the operating procedure of the operator when loading a workpiece into the automatic processing apparatus of this embodiment. While the workpiece is being input into the automatic processing device, the workpiece for manned processing can be processed by the machine tool 1o.

In step 100, the operator determines whether the workpiece carried to the carry-in table 51 is a workpiece to be machined during unmanned operation or a workpiece to be machined during manned operation. If the workpiece is to be machined during unmanned operation (YES), the process moves to step 102 and the unmanned mode of the input mode selection button 53 is selected. If the workpiece is to be machined during manned operation (No), the process moves to step 104 and the normal or express mode of the input mode selection button 53 is selected. The difference between the normal mode and the express mode during this manned operation will not be described in detail as it has little relevance to the present invention, but in the normal mode, the workpieces are stored in the multi-storey warehouse 30 in the order in which they are stored, and after the transport vehicle 41 takes out the workpieces. , the workpiece is installed on the machine tool 10 and processed, whereas the workpiece specified in the express mode is processed as soon as the machine tool 10 finishes machining the workpiece currently being processed. It is something.

In step 106, the attachment complete button 54 notifies the control bag 260 that the operator has completed attaching the workpiece to the pallet P on the carry-in table 51. Control device 6
0, upon receiving a signal from the attachment complete button 54, reads the pallet number from the dog provided on the pallet I-P to which the workpiece is attached, and selects whether it is unmanned mode from the input mode selection button 53. It is read whether the mode is normal mode or express mode, and this information is stored in the workpiece data storage area 131. Further, upon receiving the signal from the installation complete button 54, the control device 60 instructs the transport vehicle 41 to take out the workpiece from the carry-in table 51, and also directly transports the taken out workpiece to the transport vehicle 41 to the machine tool 10. or whether to store it in the three-dimensional warehouse 30. If the workpiece is to be stored in the multi-storey warehouse 30, the numbers of the storage positions 401 to 421 of this workpiece are stored in the workpiece data storage area 131 in correspondence with the pallet number.

Next, with reference to the flowchart shown in FIG. 4, the operation when the control device 6o in the automatic machining apparatus of this embodiment carries in a workpiece for unmanned machining during manned operation will be explained.

In step 200, the installation in step 106 described above is completed by receiving a signal from the completion button 54.
Check whether the workpiece is for unmanned operation or for manned operation. If the workpiece is to be machined during unmanned operation (YES), the process moves to step 202. If the workpiece is to be machined during manned operation (No), the process moves to step 206, which is a process of normal machining.

The steps after step 206 described below are for normal machining performed by a man.

In step 206, the workpiece changer 8 of the machine tool 10
It is confirmed whether or not 0 is empty using information from the numerical control device of the machine tool 1o. If the workpiece changer 80 is vacant (YES), the process moves to step 210, where the workpiece is placed directly on the workpiece changer 80 of the machine tool IO, and then the workpiece is machined in step 212. After finishing the machining, the process moves to step 214, and the finished workpiece is transferred to the loading table 51 if the loading table 51 is empty.
If it is not vacant, storage location 401 of multi-storey warehouse 30
~421 is stored in an empty space. After the above steps are completed, the process returns to step 200 to carry in the next workpiece.

On the other hand, if the workpiece changing device is not available in step 206 (No), the process moves to step 208, where the workpiece is stored in a vacant storage position 401 to 421 of the multi-story warehouse 30, and then the process returns to step 200.

The steps from step 202 described below are performed when it is determined in step 200 that the workpiece is for unmanned operation during manned operation.

In step 202, the workpieces carried into the carrying table 51 are moved to the storage position 4 of the multi-story warehouse 30 until unmanned operation is started.
Store it in an empty space from 1 to 421.

In step 204, all the workpieces to be machined during unmanned operation have been brought in, and it is determined whether or not to start unmanned operation.

That is, if the operation switching button 24 has been switched to unmanned operation by the operator (YES), the process moves to step 216 and unmanned operation is executed. If the operation has not been switched to unmanned operation (No), the process returns to step 200 to carry in the next workpiece.

The steps after step 216 explain the state of unmanned operation.

The order in which workpieces are taken out from the three-dimensional warehouse 30 in subsequent steps is determined as follows.

That is, when starting unmanned operation, the workpieces stored in the multi-storey warehouse 30 are a mixture of workpieces set to the unmanned mode at step 102 and workpieces set to the normal mode at step 104. However, during unmanned operation, there is no need to distinguish between these workpieces, so the workpieces are taken out in the order in which the four transport vehicles stored the workpieces in their storage positions.

In step 216, it is determined whether there are any unprocessed workpieces in the multi-level warehouse 30. Information as to whether or not the machining of the workpiece has been completed is stored in the workpiece data storage area 131 along with the storage position of the workpiece in the multi-dimensional warehouse 30 and the number of the pallet on which the workpiece is attached. If there are unprocessed workpieces in the multi-storey warehouse 30 (Y
ES), the process proceeds to step 218, where the workpiece is taken out from the three-dimensional warehouse 30 and placed on the workpiece changer 80 of the machine tool 10, and then the workpiece is processed in step 220. After finishing, the process moves to step 222, and the processed workpiece is returned to the storage position from which it was taken out in the multi-dimensional warehouse 30. After completing the above steps, step 21 is performed to process the next workpiece.
Return to 6.

On the other hand, if there are no unprocessed workpieces in the multi-level warehouse 30 at step 216 (No), the unmanned operation is ended.

As described above, the automatic machining device of this embodiment identifies whether the workpiece is for unmanned machining or manned machining at the time of delivery, stores it in the multi-level warehouse 30, and stores the workpiece for manned machining. Because it is possible to selectively process workpieces, the workpieces are randomly placed in a three-dimensional warehouse without considering the order in which the workpieces are brought in.
Can be stored as 0.

<Effects of the Invention> As described above, in the present invention, it is possible to identify whether a workpiece is for unmanned machining or manned machining upon delivery, store it in a multi-level warehouse, and store the workpiece for manned machining. Because it is possible to selectively process workpieces, workpieces can be stored randomly in a three-dimensional warehouse without considering the order in which the workpieces are brought in. Therefore, workpieces for unmanned machining can also be carried in during manned operation, so that the work efficiency of the operator can be improved.
