A setting setting #IQ4 is provided, and the operator performs presetting work etc. by checking the bright display on this display panel to confirm that the setting area is in the set or preset work mode. In addition, on the conveyor or turntable till, there is a limit switch and photo that emit a loading signal when an NC pallet is loaded, and notify that the jig or workpiece corresponding to the NC pallet can be taken out. A board consisting of switches, etc.
A means of verification is provided.

An overview of the logistics procedures in the system described above will be explained below. The finished products processed by each NCII machine (M), (M), ... are placed on an automatic trailer (iLT) that is guided by a guide wire (L) laid on the floor and placed in a setting area ( A pair of pallets are each placed in the opening of the setting area (STY) and in the dust station (9') and (9').Each pallet is empty. or finished or raw work.
The equipment or jigs are placed in a box and placed on top.

For example, in the initial state when machining of a certain loft is started, the NC pallet with unprocessed products set must be received by the machine tool, so the warehouse (A+ ) or (At), the pallet C loaded with unprocessed workpieces, the jig pallet 1, the empty NC pallet, and the empty pallet are moved to the crane (1) and/or
Or use Traverser+81 to access the setting area (S
Ts) or (STY). In the setting area (STs), the operator removes the finished product from the NC pallet, loads it on the finished product loading pallet, takes out the workpiece, sets it on the NC pallet using a jig, and places it on the setting setting board. Input a signal indicating that the work is completed. The computer instructs the traverser (8) to send the unloaded workpiece pallet and finished product loading pallet to a predetermined storage block (N, N') in the I82 chicken storage.

The number of workpieces taken out at this time and the number of finished products loaded are sent from setting board No. 1 to the computer, and the stored inventory quantity is adjusted. C When there is no pallet in the automatic pallet changing device in front of the machine during processing, the next processed product is automatically delivered from the automatic warehouse to the unloading device. The automatic trailer (iLT) transports the preset NG pallet f loaded with unprocessed products to the designated NC machine according to instructions from the computer, and the NC machine performs automatic processing.

In this way, the unprocessed products are sent one after another to the NC machine, and when the processing is completed, a completion signal is sent from the NC machine to the combination machine.

In response to this sign, the computer will move the automatic trailer to N.
Run up to the Cf1 machine and have it transport the processed NC pallet g to the setting area. At the same time, the computer also issues commands to the crane (1) and traverser (8) to take out the empty pallet for loading finished products and the material work pallet C as a pair and send them to the setting area (STY). When processing the same product sequentially, the operator places the finished product on the empty pallet (hereinafter referred to as the finished product pallet).
), take out the required number of unfinished products, set them, and make settings on the setting board to indicate that the set is complete.

As a result, the crane (1
1 carries the pallet to the block (N, N') of Y at the second warehouse (Am). At this time, when the number of unprocessed product pallets loaded is 0, the first warehouse (As
), then the pallets loaded with unprocessed products are taken out and sent to a predetermined block (N) in the second warehouse (A).

The pallet d loaded with finished products is transported to a predetermined block (N') of the second warehouse (Am), and when it is full, it is taken out by the unloading device α9.

All the above-mentioned warehousing and retrieval and delivery of parts in the setting area are notified to the convenience store from the warehousing and retrieval setting board (5), setting setting board +141, etc., and inventory management and each NC machine, automatic Trailer process control is performed.

What has been described so far is the +setting work procedure for the loft currently being processed, but with this system, it is possible to set the lofts that are scheduled to be processed in the near future in advance to improve the efficiency of the setting work. I can do it. This is a presetting operation, which is the setting of several pallets used for the first work in the machining loft, and is performed in the second setting area (STm). That is, as shown in FIGS. 2 to 4, the preset work starts from the preset work start setting (1). In this work, it is confirmed whether or not it is possible or appropriate to perform the presetting work at the time point. The preset operation cannot be performed when the reset operation or the first setting area (S'l'1) is overflowing or when the setting/reset operation is in progress. This kind of information can be confirmed by displaying the computer's internal data on the 4T display, mini printer, etc. by operating the setting display panel A3. If not, issue a preset information list by operating the keys on the setting panel (II).This list includes the product number, product name, and delivery date for the loft, as well as the necessary NC information.
The number of pallets, jigs, :'1 workpieces received, etc. are listed in order of delivery date. The operator selects the appropriate loft from this list and enters its number on display panel 0 (!II).

By setting this preset lot number, the computer issues a command to the crane 111 and the traverser (8) to take out the NG pallet single b1, material pallet C1, and the pallet e carrying the jig, stored in the automatic warehouse in advance, to the setting area (Srs). . Therefore, crane ti)
Take out the NC pallet single b from the designated storage block and move it to the intermediate station run (S) in the second warehouse (A8).
, (S'), and the traverser (8) transfers it from the intermediate stage changer (S), (b') to the conveyor (1(l)
After that, the NC pallet is placed on the turntable till. At the same time, the material pallet C1 and the jig pallet e are carried out to the loading stage (9) through the intermediate stations (S) and (S') (IV).

When this procedure is completed, a presetting work instruction is issued from the computer (V), and the operator uses the jig thus carried out to preset the mirror onto the NC pallet (Vl). The set dNc pallet f is stored in a predetermined block of the first warehouse (Az) via the If traverser (8), intermediate station scenes (S''), (S'), and crane (1) according to the instructions from the computer ( W)
. This re-storage command is performed by inputting only the number of completed tasks (however, if the number of pallets loaded differs from the data, the preset number of parts) from the setting panel, and having Combi and Nita report the completion of the preset. (■). Additionally, used empty pallets, pallets C1 of remaining materials, and pallets C C1 remaining jigs are also stored in predetermined blocks. The set pallets f stored in this way are timely taken out from the unloading device (2) in response to a request from the NC machine, and transported to an automatic trailer (RT).

Figure 2 shows the flow of all of the pallets mentioned above, and the symbols ~g attached to each arrow match the symbols attached to each pallet used in the explanation above, and indicate the flow of each pallet. .

As described above, the present invention is based on an automatic warehouse where elements necessary for processing such as workpieces, jigs, and NC pallets are stored separately.
The workpiece that received the machining instructions, the jig and NC pallet corresponding to this workpiece are carried out and placed in the setting area.
In a presetting system for presetting workpieces using jigs on C pallets, the workpieces, jigs, NC pallets, etc. are automatically and dynamically taken out and set from pre-stored and memorized storage positions in an automated warehouse. A means for checking whether the crane flat membrane transported to the area and the setting area is in the preset work mode OFF, and a means for checking whether an empty NC pallet is placed on the setting area. and means for confirming,
A workpiece presetting system in an automatic processing process that is characterized by loading an NC pallet corresponding to an instructed workpiece, simultaneously carrying out necessary jigs and workpieces to the corresponding loft from an automated warehouse, and presetting the workpiece. Therefore, presetting work can be done efficiently,
Efficient scheduling is possible even for machining processes with a large number of products and processes, and in particular, by concentrating on presetting work during the day, complete unmanned machining processes at night can be achieved. This greatly contributes to labor saving, and also makes it possible to completely check whether presetting is possible or not, thereby preventing confusion in the machining process due to incorrect presetting.
