[Detailed description of the invention] [Industrial application field]

The present invention relates to a processing machine having a pallet loading device.

[Prior art]

Conventionally, processing machines have been known that have a pallet loading device consisting of a loading station (hereinafter referred to as "rL/Dst") for loading workpieces onto a pallet and removing processed workpieces from the pallet, and a cart for transporting the pallet. There is. In the above L/D st, the direction of the workpiece mounting reference plane when mounting the workpiece onto the pallet is determined in advance, and the operator etc. mounts the workpiece onto the pallet in accordance with the determined direction. Then, the cotton loaded on the pallet at L/D st is transported to the processing machine using a trolley.

[Problem to be solved by the invention]

Here, if the processing machines are placed on both sides of the palletized lid in the transport direction, the workpiece mounting reference plane may differ depending on the placement position of the processing machine when viewed from the shaft head to which the processing machine's tools are attached. become. In other words, the workpiece mounting reference planes of the workpieces on the pallet transported from L/1st are 180° for each processing machine that is disposed facing each other on both sides of the pallet transporting device in the transporting direction.
The relationship is reversed. Therefore, it was necessary to create a cannibal program by converting the cycle of one machining machine by 18 degrees for the other machining machine. In this way, even if the processing machines have the same specifications, they have different specifications in operation, creating a burden on maintenance management. The present invention has been made to solve the above problems, and its purpose is to process workpieces on a pallet using the same machine program regardless of the L/D st or the arrangement of processing machines. It is an object of the present invention to provide a processing machine having a pallet loading device that can carry out pallets.

[Means for Solving the Problems] The configuration of the invention for solving the above problems includes an L/D st that loads a work on a pallet and detaches the processed work from the pallet hill, and transports the pallet. A processing machine having a pallet carrying device consisting of a cart for carrying a machine, and a shaft head direction setting means for setting the direction of a shaft head to which a tool of the processing machine is attached, and a workpiece when the workpiece is mounted on the pallet. a reference surface direction determining means for determining the direction of the mounting reference surface; and a direction of the shaft head of the processing machine set by the shaft head direction setting means and a determination result of the reference surface direction determining means. The present invention is characterized by comprising a reference surface converting means for converting the workpiece mounting reference surface of the workpiece.

[Effect]

The direction of the shaft head to which the tool of the processing machine is attached is set by the shaft head direction setting means. Further, the direction of the work mounting reference surface when the work is mounted on the pallet is determined by the reference surface direction determining means. Then, the workpiece attachment reference plane of the workpiece in the processing machine is converted by the reference plane conversion means based on the direction of the shaft head of the processing machine set by the shaft head direction setting means and the determination result of the reference plane direction determination means. Ru. In this way, the direction of the workpiece mounting reference surface of the workpiece in the processing machine is converted with respect to the preset direction of the shaft head of the processing machine, so in the combination of this pallet loading device and the processing machine, the pallet No matter which direction the processing machine is installed with respect to the carrying-in device, processing can be performed using the same cutting program.

【Example】

The present invention will be described below based on specific examples. FIG. 1 is a plan view showing a processing machine having a pallet loading device according to the present invention. In the figure, the processing line has a processing line configuration in which transport lines using trolleys are arranged on the left and right sides of the center. The upper side from the carriage line is the U (UPfler) side,
The lower side is the L (Lower) side, and the U side is HaI.
L/D st and Na1 processing machine, Nα2L/Ds on the L side
t and Nα2 processing machines are respectively arranged. Figure 2 shows Nα1 and Nn 2 L/D according to the same example.
1 is a block diagram showing the electrical configuration of a numerical control device 30 of, for example, an Nα1 processing machine. The numerical control device 30 mainly has a CP, as shown in the figure.
U31, ROM32 that stores control programs, RAM33 that stores input data, etc., and IF (interface)
34.35. The RAM 33 has an NC data area 331 for storing NC programs, and in this case, since it is an Nα1 processing machine, it is placed on the U side, and U = O, and the initial manual setting by the operator etc. is memorized and the axis head direction is set. Processing machine information area 3 that achieves the means
32 are formed. Further, the numerical control device 30 is provided with a keyboard 21 for inputting data via the IF 54 and a CRT display device 22 for displaying data. Next, based on the flowchart in FIG. 3 showing the processing procedure of the CPU 3 used in the apparatus of this embodiment, the Nα1 and Nα2 processing machines and the Nα1 and Nα2 L/Ds shown in FIG.
This will be explained with reference to an explanatory diagram showing the positional direction of the workpiece mounting reference surface A based on the combination pattern with t. First, in step 100, it is determined whether the processing machine is the Nα1 processing machine on the U side. That is, if 0 is preset in the processing machine information area 332 of the RAM 33 and it is the Nα1 processing machine on the U side, the process moves to step 102 for achieving the reference plane direction determination means. In step 102, the L/D st on which the workpiece W transferred to the Nα1 processing machine is mounted is set to Nn I L on the U side.
/Ifst is determined. Here, if the signal is O and it is determined that the pallet on which the work is mounted has been transported from NαI L/D st on the U side, the process moves to step 104. In step 104, the workpiece mounting reference plane A of the workpiece on the pallet loaded at L/D st matches the axis head direction of the Nα1 processing machine (pattern ■), and the workpiece mounting reference plane A is converted. Since it is not necessary, flag #1 is set to 0, and then the process moves to step 106, where a series of machining cycle programs are executed. Here, in step 100, if 1 is preset in the processing machine information area 332 of the RAM 33 and the processing machine is an Nα2 processing machine on the L side, the process moves to step 108 in which the reference plane direction determination means is achieved. In step 108, the direction of L/1st in which the workpiece transported to the Nα2 processing machine is mounted is determined. Here, if the signal is 0 and the pallet on which the work is mounted has been transported from NαI L/D st on the U side (pattern ◎), the process moves to step 110 for achieving the reference plane conversion means. In step 110, the workpiece mounting reference plane A and Nα2 of the workpiece on the pallet loaded at NαI L/D st
Since the axis head direction of the processing machine is deviated by 180 degrees, the workpiece mounting reference plane A is converted by 180 degrees. Then, the process moves to step 112, where flag #1 is set to 1, and then the process moves to the above-mentioned step 106, where a series of machining cycle programs are executed. In addition, in step 102, the signal from L/D st is 1, and the pallet on which the work is mounted is Nα2 L/D on the L side.
If it is determined that the item has been conveyed from st (pattern ■), the process moves to step 110 described above, and the
Since the workpiece mounting reference plane A of the workpiece on the pallet loaded at time t and the axis head direction of the Nα1 processing machine are deviated by 180°, the workpiece mounting reference plane A is converted by 180°. Then, the process moves to step 112, where flag #1 is set to 1, and then the process moves to the above-mentioned step 106, where a series of machining cycle programs are executed. Also, in step 108, the discrimination information from L/D st on which the workpiece transported to the Nα2 processing machine is mounted is 1, and the pallet on which the workpiece is mounted is on the L side Nα2L/D.
If it was transported from st. (pattern ■),
After proceeding to step 104 described above and setting flag #1=0, proceeding to step 106 described above to execute a series of machining cycle programs. Next, when the series of machining cycle programs in step 106 are completed, the process moves to step 114. In step 114, it is determined whether flag #1=o. Here, if flag #1 = 0, the workpiece mounting reference surface A of the workpiece on the pallet, which is the processing surface of the processing machine, is
Since the 18° conversion has not been performed (for patterns ■ and ■), the determination is YES and the program ends. If the flag #1 is 1 in step 114, the workpiece mounting reference plane A of the workpiece on the pallet has been converted by 18 degrees in step 110 (for patterns ■ and ◎), and the process moves to step 116. , the 180° conversion back of the work mounting reference plane A of the work on the converted pallet is executed. Then, the process moves to step 118, and after setting flag #1=0, the program ends. Note that the 180" conversion to the workpiece mounting reference plane is executed by rotating the turntable provided in the processing machine. In the above embodiment, as shown in FIG. 5(a), the processing The mechanism of the pallet exchange device attached to the machine is a shift type, and for example, the direction of the workpiece mounting reference plane A of the workpiece on the pallet transported from NoI L/D st does not change even from the top of the cart to the Nα2 processing machine. If the mechanism of the pallet changing device attached to the processing machine is a turn type, as shown in Figure 5 (b), for example, the The direction of the workpiece attachment reference plane A of the workpiece changes by 180" from the top of the cart to the No. 2 processing machine. Therefore, the mechanism of the pallet exchange device attached to the processing machine is
In the case of the turn type shown in FIG. 5(b), the arrangement information of the processing machine used for pattern determination is reversed to that of the shift type shown in FIG. 5(a), that is, L=1 is changed to U= It is sufficient to set it to O.
