Therefore, the object of the present invention is to provide a double-end tenoning machine, which can perform trimming with high precision by allowing the workpiece to pass through the machining spindle once, and at the same time perform mortise and tenon processing, and can efficiently obtain a top view. Parallelogram sheet. [Technical means to solve the problem]

In order to achieve the above purpose, the double-end tenoning machine of the invention described in Claim 1 at least includes: the main body of the abutment, and two left and right machine columns arranged in parallel, and the machine column is equipped with: conveying the workpiece to be cut forward A crawler chain, a plurality of processing spindles for processing a conveyed workpiece, and a crawler chain drive motor are characterized in that any one of the two machine columns can move in the front-back direction relative to the main body of the base to hold in any position. In the invention described in claim 2, in the constitution of claim 1, each of the crawler chains provided in the two machine columns is equipped with one of two independent crawler chain drive motors, so that the two independent crawler belts The chain drive motors run synchronously. [Effect of Invention]

According to the invention described in claim 1, by keeping the two columns at an arbitrary interval and phase difference, it is possible to set an arbitrary length of the product and angles of the four corners. , trimming can be performed with high precision, and mortise and tenon processing for fitting can be performed, so it is possible to efficiently obtain planar parallelogram-shaped plates. According to the invention described in Claim 2, the crawler chain can be driven while maintaining the phase difference between the two machine columns.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 , a double-end tenoning machine 1 includes a T-shaped abutment main body 2 and two left and right machine columns 3 and 4 respectively provided in parallel on the abutment main body 2 . Also, although the double-end tenoning machine 1 of the present invention is equipped with necessary equipment for actual operation such as a pressing mechanism for a workpiece, only the necessary parts in the description of the present invention are extracted and shown. Each machine column 3, 4 is respectively equipped with: crawler chain 5, 6, a plurality of processing spindles S1~S5 (hereinafter referred to as spindle group S) for trimming and tenon-tenon processing of the conveyed workpiece X, and track chain drive motors7,8. The crawler chains 5, 6 are provided with push claws (dogs) 9, 9... at predetermined intervals, and the push claws 9, 9... are used to push the workpiece placed on the crawler chains 5, 6 in the direction of travel. . The crawler chain drive motors 7 and 8 are connected to control means not shown, and the rotation speed of the crawler chain drive motors 7 and 8, that is, the moving speed of the crawler chains 5 and 6 is controlled by the control means.

The left column 3 is connected to the column width movement drive motor 3b provided in the base main body 2 through the ball screw 3a so that it can move in the left and right directions. Therefore, the column width movement drive motor 3b is driven by operating the control means, and the left column 3 is moved in the left-right direction along with the rotation of the ball screw 3a. When the left column 3 moves to an arbitrary position, if the column width movement drive motor 3b is stopped, the left column 3 can be held at that position. The right column 4 is connected to the column forward and backward movement driving motor 4b provided in the base main body 2 through the ball screw 4a so that it can move forward and backward. Therefore, by driving the front and rear movement drive motor 4b of the machine column, the right machine column 4 is moved forward and backward. If the machine column moves forward and backward and the drive motor 4b is stopped when the right machine column 4 moves to an arbitrary position, the machine column can be moved forward and backward at this position. Hold right column 4. The machine column width movement drive motor 3b and the machine column front and rear movement drive motor 4b are connected to a control means not shown in the figure. Using this control means, the left machine column 3 can be precisely controlled to the left and right directions with an arbitrary movement width. Move and the movement of the right machine post 4 to the forward and backward direction.

Next, the procedure of trimming the workpiece X into a parallelogram in plan view and performing mortise and tenon processing using the double-end tenoner 1 will be described using FIG. 2 . First, operate the control means to activate the column width movement drive motor 3b to move the left column 3 to the left and right. When the left column 3 reaches the desired distance between the left column 3 and the right column 4 At the position of the interval W of the product length W1, the column width movement drive motor 3b is stopped. As mentioned above, since the left machine column 3 can be precisely moved at any distance in the left and right direction, the processed plate P can obtain the desired product length W1 with high precision. Continue to operate the control means to make the machine column move forward and backward and drive the motor 4b to move the right machine column 4 forward and backward. When the right machine column 4 arrives, the phase difference between the left machine column 3 and the right machine column 4 becomes the desired angle. At the time point of the position of the phase difference D of θ1, the driving motor 4b for moving the machine column back and forth is stopped. As mentioned above, since the right machine column 4 can be precisely moved forward and backward by an arbitrary distance, the processed plate P can obtain a desired angle θ1 with high precision.

As mentioned above, after operating the control means to move the left and right machine columns 3, 4 to the position where the desired product length W1 and angle θ1 are obtained, the length W2 approximated by the desired product length W1 and angle θ1 will be adjusted in advance. The cutting object X cut at the angle θ2 is placed on the track chain 5, 6 with the rear end edge X1 of the cutting object X aligned with the push claws 9, 9, and the cutting object X is not shown in the figure. The pressing mechanism fixes the workpiece X on the crawler chain 5,6. Next, let the crawler chain drive motors 7 and 8 operate, and cooperate with the movement of the crawler chains 5 and 6, the rear end edge X1 of the workpiece X is pushed by the push claws 9 and 9, so that the workpiece X is on the machine column 3, 4 to move forward. At this time, the crawler chain drive motors 7, 8 of the left and right machine columns 3, 4 are operated synchronously by the control means, and the workpiece X can be transported while maintaining the phase difference D between the left and right machine columns 3, 4. The workpiece X moving on the machine columns 3 and 4 is trimmed and tenon-tenoned by the spindle group S. In this way, by passing the workpiece X once through the spindle group S, trimming of the product length W1 and angle θ1 of the four corners and mortise and tenon processing for fitting can be performed with high precision, so parallelism in plan view can be obtained efficiently. Plate P for quadrilateral flooring.

The above-mentioned double-end tenoning machine 1 series at least includes: the main body of the abutment 2, and two left and right machine columns 3, 4 arranged in parallel, and the machine columns 3, 4 are equipped with: a device for transporting the workpiece X to the front Crawler chains 5, 6, a plurality of processing spindles S1~S5 for processing the conveyed workpiece X, and crawler chain drive motors 7, 8, any one of the two machine columns 3, 4, can be relative to the base The table main body 2 moves in the front-rear direction and is held at an arbitrary position. According to the double-end tenoning machine 1 of such a structure, by keeping the machine columns 3, 4 at any distance and phase difference D, it can be set to any product length W1 and angle θ1, so by making the workpiece X All of the processing spindles S1 to S5 pass through once, trimming can be performed with high precision, and mortise and tenon processing for fitting can be performed, so that a plate P with a parallelogram in plan view can be obtained efficiently.

In addition, each of the crawler chains 5 and 6 provided in the two machine columns 3 and 4 is provided with one of the two independent crawler chain drive motors 7 and 8 respectively, so that the two independent crawler chain drive motors 7 and 8 run synchronously. In this way, the crawler chains 5, 6 can be driven while maintaining the phase difference D between the machine columns 3, 4.

As mentioned above, although this invention was demonstrated based on the illustration example, the technical scope of this invention is not limited to this. For example, the left and right machine columns can also be, the left machine column moves forward and backward and the right machine column moves left and right, or both left and right machine columns can move forward, backward, left and right, or one side can be fixed on the main body of the abutment And the other party can move forward, backward, left and right. In addition, the moving means of the machine column may be as long as it can move the machine column to an arbitrary position, and may not be a combination of a ball screw and each moving drive motor. In addition, the number and type of machining spindles can be arbitrarily selected as long as desired machining can be performed. Furthermore, by setting the angles of the four corners to 90°, it is possible to perform trimming and mortise and tenon processing of the cut object into a rectangular top view in the same way as the conventional double-end tenoning machine. In addition, the workpiece to be cut may be either a plate or an angle.
