Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention processes not only ordinary wood boards and plywood but also board materials such as glass epoxy resin copper-clad laminate boards in the order of primary cutting to secondary cutting to cut a plate material of a standard size into a required size. Regarding the panel source that can be used.

[0002]

2. Description of the Related Art Conventionally, when a plate material such as a glass-epoxy resin copper clad laminate is cut into a predetermined required size, an original plate material W is held by a clamp device 100 as shown in FIG. The processing method of cutting with the running saw 101 as a primary product (semi-finished product), holding the primary product as a primary product, and then again as a secondary product has been adopted. In this case, in the secondary processing, operations such as selection of the positioning pins 102 and 102, setting or re-gripping of the primary product by the clamp device 100 are required depending on the processing size.

[0003]

When the original material W is cut by one running saw 101 as described above, a place for storing the semi-finished product after the primary cutting is required. Further, in the case of secondary cutting, workers are forced to perform heavy labor such as work for taking out the semi-finished products that have been primary cut and stocked, and set operation for secondary cutting. Further, in the secondary processing, it takes a lot of time for setting when changing the set of the positioning pins for each product size, and the work efficiency is often not good. Furthermore, in the field of plate material processing factories, where there is a shortage of workers as in recent years, it is necessary to free from complicated work and heavy labor in order to solve the labor shortage. The present invention has been made in view of the above problems, and its object is to enable processing of primary cutting and secondary cutting at the same time with one machine and eliminate the need for taking out semi-finished products and changing sets. Panel source that can reduce the burden on the operator
To provide.

And the plate saw W is primarily cut by the horizontal saw 55 (FIGS. 13 and 14 (view taken along the line BB in FIG. 13)). After the primary cutting, only the material pressing device 4 is released, and the plate material vertical feeding device 7 sandwiches the plate material W between the material pressing member 74 and the material receiver 78 to retreat, and the secondary sawing unit 6 moves to the secondary cutting. (3) In the secondary cutting, the vertical saws 611 of the vertical saw unit 6 are moved in the width direction in advance so that the positions are set so as to have a predetermined width dimension. Next, the plate material longitudinal feeding device 7 is moved in the T direction (FIG. 13) while being driven by the driving device, and secondary cutting is performed by the vertical saw 611 and the like (FIG. 15). In this case,
As shown in FIG. 16 which is a view taken along the line C-D of FIG. 5, the auxiliary cylinder 77 (see FIG. 9) of the vertical plate feeder 7 is operated to press the plate W by the auxiliary presser 76, and the plate material is moved in the direction of T. Send W. (4) When the cylinder 79 of the plate material vertical feeding device 7 is operated after the secondary cutting, the material receiver 78 rotates and opens. Then, when the vertical feed device 7 is further retracted while pressing the plate material W with the auxiliary material presser 80, the secondary processed plate material W is unloaded onto the conveyor 8 and conveyed in the U direction. Although not shown, the secondly processed plate material W is carried out to the next processing machine (chamfering machine, receiving device, etc.). The plate material vertical feeding device 7 is further provided with a conveyor 8
After retreating a little further, the cylinder 79 is operated to return the material receiver 78 to the original position (FIG. 17 (view from EF arrow in FIG. 15)). (5) The material receiver 78, the main pressing cylinder 75, etc. of the vertical feed device 7 are released, and the vertical saw unit 6 is moved in the width direction and positioned so as to match the next product size (if the product size is the same as the last time, Positioning is unnecessary). Then, the plate material longitudinal feeding device 7 is moved to a position where the next plate material W to be primarily cut is grasped, the primary cutting is positioned, and the secondary cutting process is repeated.

[0015]

Since the panel saw of the present invention is constructed as described above in detail, the primary processing and the secondary processing of the original plate material can be continuously performed, which is extremely efficient. Therefore, for example, as shown in FIG. 18, even when a semi-finished product obtained by first cutting the original material W is cut into different sizes, it is not necessary to take out the semi-finished product or perform a setting operation, etc. Lost. Moreover, since the positioning and clamping of each vertical saw in the width direction at the time of the secondary cutting can be performed automatically, it is possible to change the dimension of the secondary cutting arbitrarily and perform the cutting with high accuracy. Furthermore, by incorporating an automatic data creation system that automatically creates data for automatically operating this panel saw, the desired product combination size is cut off while interactively inputting it on the cathode ray tube display (CRT). Since the data can be sent directly to this panel source, the product yield can be improved by eliminating mistakes in setting the data.
