[0025] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a cover automatic punching and dispensing device, referring to Figures 1 to 7 As shown, it includes a frame 1, on which a feed assembly 2, a punching and conveying assembly 3 and a rotary material receiving assembly 4 are arranged in sequence along the front-to-back direction. The front refers to the cover feeding end of the device, and the back refers to the cover discharging end. The feed assembly 2 includes a material cabin 21 arranged on the frame 1 along the vertical direction, and a horizontal material tray 22 and a lifting mechanism 23 are arranged in the material cabin 21. The horizontal material tray 22 can be driven by the lifting mechanism 23 to move up and down in the vertical direction. The lifting mechanism 23 can be in various forms, such as a synchronous belt, an electric slide seat, etc. In a preferred embodiment, refer to Figure 1As shown, the lifting mechanism 23 includes a sprocket 231 and a lifting motor 232 arranged on the frame of the material chamber 21. Specifically, a group of sprockets 231 distributed in the vertical direction are arranged at each of the four corners of the material chamber 21, and a mounting block is arranged at the same height position of the chain of each group of sprockets 231. The horizontal support tray 22 is installed on each mounting block. The lifting motor 232 drives the sprockets 231 at the bottom of the material chamber 21 to rotate synchronously through the reversing gear, thereby driving the horizontal support tray 22 to rise or fall. The entire stack of covers to be punched is placed on the horizontal support tray 22 and fed from bottom to top. The use of the sprocket 231 for lifting has better bearing capacity and is easier to control the lifting height. A suction cup paper feeding mechanism 24 is arranged above the material chamber 21, and the suction cup paper feeding mechanism 24 includes a vacuum suction cup 241 with an opening facing downward, and the vacuum suction cup 241 can move in the front-to-back direction and the vertical direction. The punching and conveying assembly 3 includes a front conveying belt 31, a punching mechanism 32 and a rear conveying belt 33 which are arranged in a horizontal direction in sequence. The front conveying belt 31 is connected to the top rear end of the material chamber 21. The rotary material receiving assembly 4 includes a rotary material receiving bracket 41 and a material receiving rotary disc 42. Figure 3As shown, the rear end of the material receiving turntable 42 is connected to the rotary bracket 41 through a rotating shaft 43, and a material receiving rotary cylinder 44 is provided on the rotary material receiving bracket 41. The movable end of the material receiving rotary cylinder 44 is connected to the bottom of the material receiving turntable 42. The material receiving rotary cylinder 44 can drive the material receiving turntable to reciprocate from horizontal to obliquely downward around the rotating shaft 43. When the material receiving turntable 42 is in the horizontal direction, its front end is connected to the rear end of the rear conveyor belt 33. The material receiving turntable 42 is provided with a cover pressing cylinder 45 vertically facing its upper surface, and the movable end of the cover pressing cylinder 45 is provided with a press plate 46 parallel to the material receiving turntable 42. The working process of the device is as follows: the cover to be processed is stacked on the horizontal support tray 22 in the material chamber 21, and the lifting mechanism 23 drives the horizontal support tray 22 to rise. A sensing device is provided on the top of the material chamber 21. When it is detected that the cover reaches the specified height, the suction cup paper feeding mechanism 24 drives the vacuum suction cup 241 to suck up the top cover and transport it to the conveying station of the front conveyor belt 31. The front conveyor belt 31 conveys the cover to the punching station of the punching mechanism 32 for punching. After the punching is completed, the cover is conveyed by the rear conveyor belt 33 to the receiving turntable 42. At this time, the receiving turntable 42 is in a horizontal state, and the cover pressing cylinder 45 drives The pressing plate 46 moves downward to press the cover onto the receiving turntable 42. In order to reduce the friction damage of the pressing plate 46 to the cover, the lower surface of the pressing plate 46 is preferably made of soft material, such as multiple rows of soft brushes. While the pressing plate 46 presses the cover, the receiving turntable cylinder 44 is actuated to drive the front end of the receiving turntable 42 to rotate downward. After the rotation is completed, the cover pressing cylinder 45 drives the pressing plate 46 to lift up, and the cover with holes punched is dropped downward from the receiving turntable 42. In specific applications, the conveyor belt of the inner page is located below the dropping position of the receiving turntable 42. After the cover with holes punched falls downward, it is stacked on top of the inner page with holes punched. Since the binding holes are usually located at the bottom of the book when binding, the punching position of the punching mechanism 32 is preferably at the front end of the cover page. After the material receiving turntable 42 rotates and drops the material, the binding holes on the cover are located at the bottom. After being delivered and stacked on the inner page, it can be directly delivered to the binding station. Compared with the existing processing equipment, the device can automatically complete the feeding, punching and discharging of the cover page. The punched cover can be directly delivered to the inner page conveyor belt through the rotating material receiving turntable 42, and stacked on the punched inner page, avoiding the secondary turnover of the material and greatly improving the processing efficiency; the upper suction cup material picking method can effectively reduce the friction on the cover, and the material receiving turntable 42 rotates to feed the material, so that the cover runs smoothly, and there is no need to flip or rotate during the punching or delivery process. The probability of scratches on the cover during the processing is greatly reduced, which can effectively improve the product quality.

[0027] In a preferred embodiment, referring to Figure 2As shown, the suction cup paper feeding mechanism 24 includes a paper feeding guide rail 242 and a paper feeding cylinder 243 arranged on the frame 1 along the horizontal front-back direction, a mounting seat 244 is arranged on the paper feeding guide rail 242, and the mounting seat 244 can be driven by the paper feeding cylinder 243 to move forward and backward along the paper feeding guide rail 242, and a paper suction guide rail 245 and a paper suction cylinder 246 are arranged on the mounting seat 244 along the vertical direction, and a suction cup mounting frame 247 is arranged on the paper suction guide rail 245, and the suction cup mounting frame 247 can be driven by the paper suction cylinder 246 to move up and down along the paper suction guide rail 245, and the vacuum suction cup 241 is mounted on the suction cup mounting frame 247. The transmission action using this structure is simple and efficient, and the cost is low.

[0028] The punching mechanism 32 is arranged between the front conveying belt 31 and the rear conveying belt 33. Figure 5 As shown, the punching mechanism 32 includes a punching base 321 arranged horizontally, the front end of the upper surface of the punching base 231 is connected to the front conveying belt 31, and the rear end is connected to the rear conveying belt 33, and a cylinder puncher 322 is arranged above the punching base 231. Further, the frame 1 is provided with a rear stopper 323 that can move up and down at the rear of the punching base 321, and left and right aligning plates 324 are arranged on both sides of the punching base 321, and front and rear aligning plates 325 are arranged in front of the punching base 321. After the cover is conveyed to the punching station by the front conveying belt 31, the rear stopper 323 rises upward to block the cover from moving forward, and the left and right aligning plates 324 and the front and rear aligning plates 325 move to align and position the cover, and the aligning is to avoid deviation in the position of the punching holes of the cover. After the cylinder puncher 322 punches holes in the cover, the rear stopper 323 is reset, and the punched cover is transported to the rotary material receiving assembly 4 by the rear conveyor belt 33. In a specific application, the front conveyor belt 31 and the rear conveyor belt 33 are both composed of multiple parallel belts, with gaps between adjacent belts, and the rear stopper 323 rises from the gap to stop the material, and the slapping parts of the lower edges of the front and rear slapping plates 325 move back and forth in the gap, and the rear stopper 323 and the front and rear slapping plates 325 are in motion without affecting the operation of the conveyor belt.

[0029] In order to make the cover on the front and rear conveyor belts and before and after the punching mechanism 32 more stable and smooth, in a preferred embodiment, refer to Figures 4 to 6As shown, the frame 1 is provided with a pressure roller bracket 34 above the front conveyor belt 31 and the rear conveyor belt 33, and each pressure roller bracket 34 is provided with a pressure roller rocker arm 35 toward the front end and the rear end of the corresponding conveyor belt, and each pressure roller bracket 34 is provided with a transmission shaft 36 corresponding to each pressure roller rocker arm 35 along the horizontal lateral direction, and the inner end of each pressure roller rocker arm 35 is connected to the corresponding transmission shaft 36, and the outer end of each pressure roller rocker arm 35 is provided with a belt pressing roller 37. When the transmission shaft 36 reciprocates, the belt pressing roller 37 at the outer end of the corresponding pressure roller rocker arm 35 is driven to lift or press down. When the belt pressing roller 37 is pressed down, it presses against the front end or the rear end of the corresponding conveyor belt. Each transmission shaft 36 is provided with a pulley 38, and each pressure roller bracket 34 is provided with a pressure roller driving motor 39. When the pressure roller driving motor 39 is working, it drives the transmission shaft 36 to rotate by driving the pulley 38. When the vacuum suction cup 241 sucks and conveys the paper, the pinch roller 37 at the front end of the front conveyor belt 31 is in a lifted state. When the paper is conveyed to the front end of the front conveyor belt 31, the vacuum suction cup 241 releases the vacuum to place the paper on the front conveyor belt 31. The pinch roller 37 is pressed down to the front end of the front conveyor belt 31. The pinch roller 37 can rotate freely and has no rotational power. The cover paper to be punched is pressed between the pinch roller 37 and the front conveyor belt 31. The front conveyor belt 31 continues to operate. When the cover is smoothly conveyed to the rear end of the front conveyor belt 31, the pinch roller 37 at the front end is lifted and the pinch roller 37 at the rear end is The pressing roller 37 is pressed down, and the cover is continuously transferred to the punching base 321, and the rear stopper 323 is raised to block the cover from continuing to move forward. At this time, the rear end of the cover has entered the front end of the rear conveying belt 33, and the pressing roller 37 at the front end of the rear conveying belt 33 is in a raised state. After the cover is slapped and punched, the rear stopper 323 is reset downward, and the pressing roller 37 at the front end of the rear conveying belt 33 is pressed down, and the rear conveying belt 33 drives the cover to the rear end. When the cover reaches the rear end of the rear conveying belt 33, the pressing roller 37 at this place is pressed down, and the rear conveying belt 33 transfers the cover to the receiving turntable 42. It is a common technical means to drive the transmission shaft 36 to rotate by the motor-driven pulley 38. Therefore, in this technical solution, the transmission relationship between the pressing wheel driving motor 39 and the pulley 38 is not specifically described. In addition, the pressing wheel rocker arm 35 can also be driven to rotate up and down by gear transmission and other methods, which are all conventional means. By providing the belt-pressing roller 37, the operation of the cover on the conveyor belt can be made more stable. At the same time, when only part of the cover enters the conveyor belt area or when most of the cover has been sent out by the conveyor belt, the cover can be continuously transported. In specific applications, a supporting pad layer can be provided under the conveyor belt, so that the force of the belt-pressing roller 37 when pressing down on the conveyor belt is more uniform and stable. In the utility model, each motor, cylinder and conveyor belt are uniformly controlled by a controller to ensure that each part acts in coordination according to the operation process.

[0030] In order to make the cover unloading from the material receiving turntable 42 smoother, in a preferred embodiment, referring to Figure 3 and Figure 6 As shown, a material receiving push claw cylinder 47 is provided below the material receiving turntable 42 and faces the front end. A material receiving push claw 48 is connected to the movable end of the material receiving push claw cylinder 47. The material receiving push claw 48 extends vertically out of the upper surface of the material receiving turntable 42. The material receiving push claw 48 can move forward and backward under the drive of the material receiving push claw cylinder 47. When the cover is transmitted to the material receiving turntable 42 by the rear conveying belt 33, the material receiving push claw 48 blocks and limits the cover. When the material receiving turntable 42 rotates downward and the material pressing plate 46 is lifted, the material receiving push claw cylinder 47 drives the material receiving push claw 48 to move forward and push the cover out of the material receiving turntable 42. A stop buffer 49 can also be provided on the rotary material receiving bracket 41. The stop buffer 49 is located below the material receiving turntable 42. When the material receiving turntable 42 rotates downward, the stop buffer 49 is used to limit and buffer.
