Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to FIG. 1 , FIG. 2 , and FIG. 3A to FIG. 3C , an embodiment of the present invention will be described in detail below in conjunction with a schematic structural diagram of a chain assembly machine.

Please refer to FIG. 1 , the driving device 1 of the chain joint assembly machine includes a motor 11 and a main shaft 12 .

Please refer to Fig. 1, Fig. 2, Fig. 3A to Fig. 3C, the tablet loading device 5 in the present invention includes a lifting device, that is, a tablet loading hydraulic cylinder 51, and a tablet pressing device 52 connected to the lower end of the tablet loading hydraulic cylinder 51. The tablet loading hydraulic cylinder 51 is connected with the control device 2; the tablet pressing device 52 includes a tablet pressing die 521, and a pair of guide strikers 523 that are elastically connected with the tablet pressing die 521 through a spring 522 and installed inside it, the guide The lower part of the striker 523 exposes the tablet die 521 . The film loading device 5 also includes a first film loading cam 131 and a sensor 141 corresponding thereto, a second film loading cam 132 and a sensor 142 corresponding thereto, and the first film loading cam 131 and the second film loading cam 132 are all arranged on On the main shaft 12 , both the sensor 141 and the sensor 142 are connected to the controller 2 .

Please refer to FIG. 1 , FIG. 2 , and FIG. 3A to FIG. 3C . When the chip loading device 5 is working, as shown in FIG. 3A , the chain piece 4 is conveyed in place, directly above the pin shaft 3, directly below the tablet pressing die 521, and the guide striker 523 is just above the chain piece hole of the chain piece 4. Corresponding to the pin shaft 3, at this time, as shown in Figure 1, Figure 2 and Figure 3A, the sensor 141 senses that the first film loading cam 131 rotates to a predetermined position, and obtains the rotational position of the first film loading cam 131 The information is transmitted to the control device 2, and the control device 2 sends a signal to the tablet loading hydraulic cylinder 51 according to the rotation position information to control the tablet loading hydraulic cylinder 51 to go down, and the tablet loading hydraulic cylinder 51 pushes the tablet compression die 521 to move downward, at a certain Within the range of the rotation position (that is, when the protruding surface of the cam is continuously close to the sensor), the first tablet loading cam 131 continues to rotate so that the tablet pressing die 521 continues to move downward.

As shown in Figure 3B, since the guide striker 523 protrudes from the lower part of the tablet die 521, the guide striker 523 first passes through the chain hole of the chain piece 4, and contacts with the top of the pin shaft 3, the pin shaft 3 is positioned, installed The tablet hydraulic cylinder 51 continues to push, and the spring 522 between the tablet pressing die 521 and the guide striker 523 is continuously compressed. The position has exceeded the aforementioned rotation position range (at this time, the protruding surface of the cam continues to move away from the sensor), the sensor 141 transmits the currently obtained information on the rotation position of the first film loading cam 131 to the control device 2, and the control device 2 controls the film loading hydraulic cylinder 51 ascends gradually, and the tablet die 521 promptly ascends, and at this moment, the spring 522 between the tablet die 521 and the guide striker 523 recovers gradually.

As shown in Figure 3C, due to the reset action of the spring 522, the guide striker 523 has been in contact with the top of the pin shaft 3. When the guide striker 523 and the pin shaft 3 are about to disengage (the spring returns to normal), the first position on the motor shaft The second film loading cam 132 rotates to a certain rotational position and is sensed by the sensor 142. The sensor 142 transmits the rotational position information of the second film loading cam 132 obtained at this time to the control device 2, and the control device 2 sends a signal to control the hydraulic cylinder. 51 goes down, and the tablet press die 521 also goes down. As mentioned above, within a certain range of rotation position (that is, when the cam protruding surface continues to approach the sensor), the second tablet loading cam 132 continues to rotate so that the tablet press die 521 Continue to move downward until the pressing die 521 touches the chain piece 4, the hydraulic cylinder 51 continues to move downward, pushes the pressing die 521 to press the chain piece 4 downward, and the chain piece 4 is pressed down to a suitable position, so that part of the pin shaft 3 passes through the chain film hole, because the second film loading cam 132 continues to rotate, and its rotational position has exceeded the aforementioned rotational position range at this time (that is, when the cam protruding surface continues to move away from the sensor), the sensor 142 will obtain the currently obtained second film loading cam 132 The rotation position information is transmitted to the control device 2, and the control device 2 controls the tablet loading hydraulic cylinder 51 to move upward, and drives the tablet pressing die 521 to move upward to complete the tablet loading.

The tablet loading device 5 in the present invention is driven by double cams (131, 132) to control the action of the tablet compression die 521, which has higher reliability. Prolong the contact time between the guide striker 523 and the pin shaft 3, prolong the time before the pressing die 521 is pressed down, and give the chain piece device sufficient return time to avoid the chain piece device not returning due to the pressing down of the pressing die 521 , causing the tablet pressing die 521 to squeeze the chain feeding device, thereby causing damage to the equipment (for example, damage to the feeding plate of the chain feeding device).

The lifting device in the present invention is a tablet loading hydraulic cylinder 51, which has reliable performance and large thrust, and can effectively push the tablet pressing die 521 to complete the tablet loading work; the lifting device in the present invention can also include servo motors, gears and racks, and gears It is arranged on the motor shaft and meshes with the rack. The rack is connected to the tablet pressing device 52. The servo motor drives the tablet pressing device 52 to move up and down through forward and reverse rotation. The structure of the device is simple and the movement is precise; the lifting device in the present invention is also Can be air cylinder, and its weight is lighter, and the thrust that produces also can satisfy the requirement of film loading work.

The guide striker 523 in the present invention is elastically connected to the tablet pressing die 521 through a spring 522, and it may also be elastically connected to the tablet pressing die 521 through a cylinder or the like.

The control device in the present invention adopts a PLC intelligent control device, which has a high degree of automation and a good man-machine interface, and can greatly improve production efficiency.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the implementation scope of the present invention; if it does not depart from the spirit and scope of the present invention, any modification or equivalent replacement of the present invention shall be covered by the claims of the present invention. within the scope of protection.
