Description of the Invention: [Technical Field] The present invention provides a control device for intermittently shifting a belt for a punch press, and specifically refers to a metal strip for use in punching, in particular When the mold is tested and the mold is installed, the intermittent movement of the metal strip in the horizontal interval of the material can be automatically controlled to completely eliminate the manual operation and improve personal safety. [Prior Art] The metal sheet material of the workpiece to be processed for punching is conventionally processed, and when it is horizontally fed, it is intermittently conveyed by a belt feeder to control the metal. The clamping and release of the strip with its horizontal advancement or pause are performed by the clamp. The clamp system is controlled by the (four) cylinder, the electromagnetic switch and the relay. These traditional mechanical and electric it (4) have poor ejacency and speed. Slow, especially the timing control of the fixture shift is easy to produce dimensional error', which causes the tape to produce tolerances on the intermittent displacement. The progressiveness of the tolerance will result in a larger size error value, which will result in multiple molds being repeatedly stamped on the tape. The position is not accurate, and the quality of the products after processing is not good. It is also worth mentioning that the intermittent horizontal shift of the test strip before the processing of the strip and the installation of the mold are controlled by the manual and visual displacement, so it is easy to cause injury. In the above, how to make the intermittent displacement of the metal strip used for punch press forming can be effectively controlled, and the manual operation without the manual operation is the subject of this case.

According to the foregoing device features, as shown in FIG. 4, the upper side gears of the active roller 丄0 and the passive roller 20 are respectively connected with the upper gear 1 〇; the upper and lower gears 2011 and 2〇1 of the lower gear 201 can be Intermittent meshing or 1288672 separation; the two outer fixed shafts 103, 1〇3 of the active roller ίο are abutted to the two-sided bases 80, 80', wherein a fixed shaft 1〇3' is driven by the transmission element 200 The power output shafts 8 5 i of the servo motor 8 5 are connected. As shown in Figures 1, 2, 2, 4 and 5, the present invention provides a control method for intermittently shifting a belt for a punch press, comprising: · an active roller 1 0; - driven by an active roller 1 The passive roller 2 has its tread 2 2 and the tread 1 2 of the active roller 1 Q form a minimum gap l 2 , which is used for the central belt 3 Q, and the passive roller 2 〇 is driven by the active roller 10 The strip 3 〇 is linearly outputted; when the two gaps 2 2 and 1 2 have a large gap LX greater than the minimum gap L 2 , the passive roller 20 and the active roller 1 停 are in a stopped state. According to the foregoing method, in the tread 1 2 of the driving roller 10, a processed strip 3 水平 is horizontally placed, the thickness of which is greater than or equal to the minimum gap L 2 , and the active roller 2 〇 drives the passive roller 2 〇 When the reverse rotation is performed, the material ▼ 3 0 is driven forward by a distance·, and when the active roller 10 and the passive roller 20 have a large gap L 1 , the tape 3 停 is in a stopped state. According to another method, wherein the passive roller 2 can linearly shift up and down to control the formation of the minimum gap L 2 between the two treads 2 2 and 12 at different timings, the minimum gap L 2 is formed, The active roller 1 〇 rotates to drive the passive roller 2 同步 to rotate in opposite directions in synchronism to feed the belt 3 〇 forward by a certain distance. 1288672 [Embodiment] (1). As shown in Figures -, 2, 3, and 4, the two motors 86 and 85 are controlled by a controller (not shown) so that they can be programmed to make the servo The motors 8 6 and 8 5 can control the rotation speed and the rotation angle position of the power output shafts 8 6 1 and 8 5 1 at different timings, and the rotation rate of the main and passive rollers 1〇 and 2〇 can be controlled at different timings. The position control with the rotation angle can further control the shift rate of the upper and lower linear shifting actions of the passive roller 20 at different timings and the large and small gap control to control the minimum gap L 2 to be formed at different timings (as shown in Fig. 6). Show). The power output shaft 8 6 i of the servo motor 86 drives the transmission element 2 〇0 to drive the rotation shaft 52 to rotate, and the rotation speed and the angular position of the rotation are programmable, and different speeds and rotations can be controlled at different timings. The angular position, when the rotating shaft 52 rotates, drives the two eccentric cams 50, (50) to rotate synchronously. As shown in Fig. 5, the two convex portions 51, 53 of the eccentric cams 50, (50) are linearly vertical. In the state, the upper convex portion 5 1 is pressed against the outer wheel surface 552 of the bearing 55, and the two projections 4 〇, (4 〇) are further raised by a set distance, and the sliding surfaces 4 2, 4 4 are also The bearings 6 β, Θ 6 , slide upward by a distance, the elastic elements 7 1 , 7 2 are contracted, because the two fixed shafts 2 1 , ( 2 1 ) of the passive roller 20 are alived on the bump 40, ( 40) in the circular hole 401, so when the bumps 4〇, (4 〇) slide up, the passive roller 2 〇 rises a certain distance 'to make a large gap L 1 between the two wheel faces 1 2, 2 2 1288672 L 1 is larger than the thickness of the metal strip 3 ◦, so the strip 3 位于 is located on the tread of the active roller 1 丄 2 , Was parked state. (2) As shown in Fig. 6, when the two convex portions 5 1 and 5 3 of the eccentric cams 5 G and ( 5 0 ) are in a lateral state, the outer race surface 5 5 2 of the bearing 55 is not pressed by the convex portion 5 1 Therefore, the rest tension of the elastic members 7丄, 7 2 is pressed against the entire bump 4〇 in the linear bearings 66, 66, and is displaced downward by a certain distance, and the bumps 4〇 are synchronously driven to move the passive roller 2 〇 downward.

The rotation of the eccentric cam 50 described above and the timely rotation of the active roller 1 ’ can very accurately control the distance dimension of the belt 3 〇 intermittent displacement and the control time of the belt 3 可 can be controlled. When the mold is to be tested, that is, when the manual test mold and the mold installation work before the large-scale press processing are performed, the control device (not shown) to which the two servo motors 8 5 and 8 are operated is operated (pressed). The required control value can accurately set the discharge belt 3 〇 forward displacement distance and stop 10 1288672 set time, completely eliminating the manual operation during the trial and installation of the mold. In summary, the functions of the features of the present invention have been achieved with great success, and the applicant submits an application according to law. 11 1288672 [Simple description of the drawings] The first figure is a combined perspective view of the present invention.
