Since it is common to the conventional example, the common members and mechanisms are designated by the same reference numerals, and the duplicated description will be omitted.
In FIG. 1 and FIG. 2, the rollers 7 of the pressure belts 8 and 9,
7 ... Are urged by the constant pressure cylinders 17 and 17 at right angles to the upper surfaces of the block chains 5 and 6, and are plate members sandwiched between the block chains 5 (6) and the pressing belts 8 (9). A constant clamping force acts on M regardless of the thickness. In the embodiment, it is 0 to 35 mm.
If the plate material is thick, the structure does not require adjustment on the machine body side. Further, the block chains 5 and 6 are provided with restricting members 18 and 18 for abutting the front edge of the plate material M so that the front edge is perpendicular to the feeding direction, and the speed of the pressing belts 8 and 9 is increased. Is made slightly faster than the speed of the block chains 5 and 6, and the front short edge of the plate material M is constantly pressed against the restriction member 18 in the feeding process,
Care is taken not to change the posture.

Limit switches 19 and 20 for detecting the positions of the plate members are provided on the carry-in side and the carry-out side, respectively.
On the loading side, the front edge of the plate material M is the block chain 5
A limit switch 19 is attached to a position just before being sandwiched between (6) and the pressing belt 8 (9) to confirm that the plate material is in a free state on the carry-in side, and at the carry-out side, a rear edge of the plate material M. The limit switch 20 is attached to a position immediately before the part is removed from the state of being sandwiched between the block chain 5 (6) and the pressing belt 8 (9), and it is confirmed that the plate material M is just before the completion of passing of the material feeding mechanism. be able to. Further, each of the blade mechanisms 14, 15 and 16 is provided with a retracting mechanism for retracting the blade on both sides only with the rotary blade or integrally with the motor. In the embodiment, the blade mechanisms 14 and 15 for cutting and scoring will be described as an example, and the slider 23 is provided on the motor base 22 attached to the support column 21.
Motors 14a and 15a are fixed to the sliders 23, and rotary blades 14b and 15b are attached to the rotary shafts of the motors 14a and 15a, respectively.
It has a structure in which 15b is fixed, and the motor base 21 can be moved in the horizontal direction by a manual handle 24, and is used for replacement of a rotary blade. Also motor base 2
2 and the slider 23 between the cylinder 2 and
5, 5 and 25 are interposed, and a small stroke can be retracted by the operation of the cylinder 25. A limit switch 26 is provided on the motor base 22 to detect the retracting operation. As for the cutting blade mechanism 15, a retracting mechanism equivalent to that of the cutting blade mechanism 14 and the cutting blade mechanism 15 is adopted. Further, the processing machine of the embodiment is provided with a return mechanism for controlling the intervals between the columns 2 and 3, the starting and stopping of the material feeding motor 10, the rotating direction and speed thereof, the operation of the cylinder 25, and the like according to a program. The computer 27 is installed and each of the limit switches 1
The detection signals of 9, 20, and 16 are input through the interface. In this program, the limit switch 20 reaches the position immediately before the rear end edge of the plate material M comes out of the state where it is sandwiched between the block chain 5 (6) and the pressing belt 8 (9). If the confirmation signal is received, the feeding motor 10 is temporarily stopped, the cylinder is operated to retract the blade mechanisms 14, 15, 16 to the left and right, and then the feeding motor 10 is turned on. It includes a series of controls in which the plate material M is returned in the reverse direction and returned to the carry-in side, and when the limit switch 19 confirms that the plate material M is in a free state on the carry-in side, the material feeding motor 10 is stopped.

The case of processing one plate material by using the processing machine configured as described above will be described with reference to the flow chart shown in FIG. 3 and the process explanatory diagrams shown in FIGS. 4 to 8. First, in step S1, the dimensions of the plate material M and machining work data are input to the computer 27, and in step S2, the control mechanism is operated. In S3, the control mechanism quickly adjusts the interval between the columns 2 and 3 based on the width and the machining shape data on both sides of the size of the plate material M, and also extends the blade to enter the machining standby state. Therefore, the plate material M is loaded on the loading side (IN) by S4.
Set to the feeding position of (Fig. 4). In subsequent S5, the material feeding motor 10 is started by pressing the start button,
The plate material M is sent to the carry-out side (OUT), and in the process of being sent out, both sides are processed by S6. Plate material M
When the rear end reaches a position just before leaving the material feeding mechanism, a detection signal is sent from the limit switch 20 in S7, and the material feeding motor 10 is stopped by the detection signal in S8 (FIG. 5). Then in S9, the blade mechanism 14, 15, 16
Is retracted (FIG. 6), and if the limit switch 26 confirms that the blade mechanisms 14, 15, 16 are retracted in S10, S
At 11, the material feeding motor 10 is rotated in the reverse direction, and the plate material M after the first processing is returned to the carry-in side (IN). When the plate material M reaches the carry-in side (IN) and separates from the material feeding mechanism, a detection signal is sent from the limit switch 19 in S12, and the material feeding motor 10 is stopped by the detection signal in S13 (FIG. 7).

The returned plate material M is processed only on both sides by the first processing. Therefore, in S14, it is confirmed whether or not all the programs based on the machining data input in S1 have been executed, that is, whether the second machining is necessary. If it is determined that the second machining is necessary, the machining material is processed in S15. Among the dimensions of M, the column interval is quickly adjusted based on the length and the machining shape data of the front and rear edges, and the cutting tool is extended to enter the machining standby state. Next, by horizontally rotating the plate material by 90 degrees in S16, the posture is changed so that the front and rear edges are located on both sides, and the sheet is fed in from the carry-in side (IN). In the same manner as above, the start button is pressed. Then, the sheet feeding motor 10 is activated to send the plate material M to the carry-out side (OUT), and in the process of being sent out, S1
Both front and rear edges are processed by 9 (FIG. 8). After that, the steps from S7 to S12 are repeated, and the product for which the second processing has been completed is returned to the carry-in side (IN). In this way, the operator can continuously perform the first and second processing while being on the carry-out side.

The control program of the above embodiment is designed to return the product, which has been subjected to the second processing, to the carry-in side. However, after the second processing is completed, the product is kept sent out to the carry-out side, and the product is sent from the carry-out side. You can change it so that it is carried out, you can repeat the program based on the same data multiple times, or you can input multiple data at once and control it based on the data selected from among them, It is also possible to cancel the program and use it as the same one-way type as before. Further, the method of the present invention can be easily carried out by using the processing machine of the present invention, but it is also possible to manually control while visually confirming the position of the plate material without modifying the existing processing machine. Is.
It is also possible to connect a general-purpose computer to an existing processing machine, input a control program to the computer, and provide the same function by a simple modification that adds a detection mechanism and a blade retracting mechanism.

Since the processing machine of this embodiment is of a type in which the tip of the plate material is pressed against the regulating member to be fed in, the block chain is largely projected to the carry-in side as compared with the back-pressing type in which the regulating member is pressed against the rear end and conveyed. It is not necessary to do so, and the total length of the main body can be shortened, which is advantageous in transportation.

In the embodiment, only one column is movable, but if both columns are movable so as to open and close to the left and right with respect to the center, the width adjustment time is halved, and the motor It is expected that the workability will be improved by increasing the speed by increasing the ability of. In addition, the structure of each mechanism can be changed as appropriate, such as using a non-contact type detection mechanism or providing a feed claw on the block chain and pushing it in while pushing the rear edge of the wood processing material. For example, when an abnormal detection signal is received, it is desirable to display a lamp in the program, interrupt the execution of the program, and groove a safety measure so that the operator does not proceed unless the operator presses the confirmation switch. .

[0014]

According to the method of the present invention, the two-way system is adopted in which the processed material is sent to the carry-in side without being sent from the carry-out side. Since it is not necessary to send the processed material after finishing the processing from the carry-out side to the carry-in side one by one, work efficiency is improved and productivity can be increased. Further, by using the processing machine of the present invention, it is automatically returned without any troublesome switch operation.
All you have to do is to rotate it horizontally.
