Description

Technical Field

[0001] This utility model relates to the field of counting in paperboard production, specifically a counting device for paperboard output. Background Technology

[0002] In the field of integrated cardboard stapling and gluing machines, after cardboard is stapled and formed, it needs to be conveyed, counted, and grouped for output in an orderly manner. This process directly affects the efficiency of subsequent warehousing, transportation, and downstream processes. With the increasing automation of cardboard stapling and gluing production, higher demands are placed on the accuracy of cardboard counting, the stability of conveying, and the regularity of grouped output. Traditional manual counting methods not only struggle to keep up with the high-speed production pace of stapling and gluing machines but are also prone to counting errors due to fatigue and negligence, leading to discrepancies in product quantities and impacting the company's production plans and economic benefits. Therefore, automated counting devices have become an indispensable key piece of equipment in cardboard stapling and gluing production lines. In the production process of cardboard stapling and gluing machines, the lack of a dedicated cardboard straightening mechanism when the cardboard is conveyed from the gluing mechanism to the counting device makes it impossible to convey the cardboard one by one, easily causing cardboard overlap and resulting in counting errors by the counting sensor, significantly reducing counting accuracy.

Detailed Implementation

[0016] Example 1 like Figures 1 to 7As shown, a cardboard output counting device includes a paper feeding unit 1, a middle conveying unit 2, and a counting output unit 3. The two ends of the middle conveying unit 2 are respectively connected to the paper feeding unit 1 and the counting output unit 3. The middle conveying unit 2 feeds the cardboard input from the paper feeding unit 1 one by one into the counting output unit 3. The counting output unit 3 includes a counting output frame 4, conveyor belts 5, and pusher plates 6. Several conveyor belts 5 are installed at intervals along the vertical conveying direction of the cardboard on the counting output frame 4. The conveyor belts 5 are installed at an angle, with their lower ends positioned close to the middle conveying unit 2. Pusher plates 6 are positioned between adjacent conveyor belts 5, close to the middle conveying unit 2. The pusher plates 6 are rotatably mounted below the conveyor belts 5, with their rotation axis perpendicular to the conveying line of the conveyor belts 5. A counting photoelectric sensor is installed on the counting output frame 4. The counting photoelectric sensor is used to count the cardboard input from the middle conveying unit 2. When the counting photoelectric sensor... When the sensor's count value equals the set value, the pusher 6 pushes the stacked cardboard group forward for counting output. The cardboard processed by the stapler and gluer is fed into the central conveyor unit 2 through the paper feeding unit 1. The conveyor unit 2 transports the cardboard one by one, ensuring that the cardboard is transported to the counting output unit 3 one by one, avoiding cardboard overlap that affects counting accuracy. The counting photoelectric sensor counts the cardboard input into the central conveyor unit 2 in real time. The cardboard output from the central conveyor unit 2 is stacked on the conveyor belt 5. Each time a cardboard is input, the conveyor belt 5 drives the cardboard forward a certain distance, causing the cardboard to be stacked at an angle and staggered, thus ensuring that the height of the cardboard output from the central conveyor unit 2 on the conveyor belt 5 remains constant. When the count value of the counting photoelectric sensor reaches the set value, the stacked cardboard group is pushed out, avoiding errors and fatigue problems caused by manual counting. The counting accuracy is improved by counting one by one, ensuring the accuracy of the counting results.

[0017] Example 2 Based on Example 1, such as Figures 1 to 3As shown, each conveyor belt 5 has two support plates 7 at its end, with the conveyor belt 5 located between the two support plates 7. The support plates 7 are fixed to the counting output frame 4. Each support plate 7 has a horizontal section and an inclined section. The high end of the inclined section smoothly connects to the horizontal section, and the low end of the inclined section connects to the conveying surface of the conveyor belt 5. A paper pusher shaft 9 is located below the conveyor belt 5 and is rotatably mounted on a slide 32. A linear drive module 33 is mounted on the counting output frame 4 and is parallel to the conveyor belt 5. The paper pusher shaft 9 is rotatably mounted on a sliding seat of the linear drive module 33, and a paper pusher motor is mounted on the sliding seat. The output shaft of the paper pusher motor is driven and connected to the paper pusher shaft 9. One end of the paper pusher 6 is fixedly connected to the paper pusher shaft 9. When the counting photoelectric sensor... Once the count reaches the set value, the pusher motor drives the pusher shaft 9 to rotate, which in turn drives the pusher 6 to rotate, causing the pusher 6 to extend out from between the conveyor belts 5. Then, under the action of the linear drive module 33, the pusher 6 pushes the cardboard group towards the support plate 7. Due to the staggered arrangement of the cardboard, the pusher 6 first contacts the top cardboard, pushing it to move so that it is flush with the adjacent bottom cardboard. Then, it pushes the two flush cardboards to move so that they are flush with the adjacent bottom cardboard. This process is repeated, and in conjunction with the conveyor belt 5, the cardboard group is pushed flat onto the support plate 7, facilitating subsequent bundling operations. It should be noted that the pushing speed of the pusher 6 is greater than the conveying speed of the conveyor belt 5, so that the cardboard is stacked flat on the support plate 7.

[0018] Furthermore, the support plate 7 is rotatably equipped with several auxiliary paper-discharging wheels 8 on the side wall of the horizontal section. The top surface of the auxiliary paper-discharging wheels 8 is higher than the top surface of the support plate 7, which changes the movement of the cardboard on the support plate 7 into rolling contact, greatly reducing friction and ensuring that the cardboard will not be damaged during the conveying process.

[0019] Example 3 Based on Example 2, such as Figures 1 to 5As shown, the central conveying unit 2 includes a central conveyor frame 27, central conveyor belts 28, a receiving plate mechanism, and a paper-blocking mechanism. Several central conveyor belts 28 are installed at intervals on the central conveyor frame 27 along a direction perpendicular to the paperboard's conveying direction. The receiving plate mechanism includes multiple receiving plates 29, which are arranged at equal intervals along a direction perpendicular to the paperboard's conveying direction. Each receiving plate 29 is located between two adjacent central conveyor belts 28 and has a degree of freedom to move along the height direction of the central conveyor frame 27. The paper-blocking mechanism includes side plates 30 and paper-blocking plates 31. Two side plates 30 are arranged at intervals along a direction perpendicular to the paperboard's conveying direction. The side plates 30 are slidably mounted on the central conveyor frame 27, and their movement direction is parallel to the paperboard's conveying direction. The paper-blocking plates 31... The two ends are respectively slidably set on the two side plates 30. The guide plate 31 moves along the height direction of the side plate 30. Each movement of the guide plate 31 ensures that the gap between the guide plate 31 and the middle conveyor belt 28 can only allow one cardboard to pass through. The receiving plate 29 moves upward to catch the cardboard output by the paper feeding unit 1. Then the receiving plate 29 moves downward to place the cardboard on the middle conveyor belt 28. The height of the guide plate 31 is adjusted in advance according to the thickness of the cardboard so that the gap between the guide plate 31 and the middle conveyor belt 28 can only allow one cardboard to pass through. Even if multiple cardboards are simultaneously fed into the middle conveyor belt 28, the guide plate 31 can pass through the guide plate 31 one by one, realizing the one-by-one delivery of the cardboard and making the subsequent counting operation more accurate.

[0020] Example 4 Based on Embodiment 3, each side plate 30 is equipped with a lead screw drive mechanism, which includes a lead screw 34 and a lead screw nut seat 35. The lead screw 34 is rotatably connected to the central conveyor frame 27, and the lead screw nut seat 35 is threaded onto the lead screw 34. The side plate 30 is mounted on the lead screw nut seat 35. A main shaft 36 is provided between the two lead screws 34, and the main shaft 36 is rotatably connected to the central conveyor frame 27. One end of the lead screw 34 is connected to a first bevel gear 37, which meshes with a second bevel gear 38. The second bevel gear 38 is mounted on the main shaft 36. A lead screw motor 39 is mounted on the central conveyor frame 27, and the output shaft of the lead screw motor 39 is drively connected to the main shaft 36. A drive shaft 40 is provided between the two side plates 30, and the drive shaft 40 is rotatably connected to the side plate 30. An eccentric wheel 41 is fixedly sleeved on the drive shaft 40, and an eccentric wheel connecting plate 42 is fixed on the baffle plate 31. The eccentric wheel connecting plate 42 contacts the eccentric wheel 41. On the top surface, a geared motor 43 is installed on one of the side plates 30. The output shaft of the geared motor 43 is connected to the drive shaft 40, which drives the main shaft 36 to move through the lead screw motor 39. The main shaft 36 drives the lead screw 34 to rotate through the meshing of the first bevel gear 37 and the second bevel gear 38, thereby causing the side plate 30 to move linearly along the axial direction of the lead screw 34, driving the connecting plate mechanism and the paper-stopping mechanism to move closer to or away from the paper feeding unit 1, in order to adjust the relative position between them and the paper feeding unit 1. The geared motor 43 drives the drive shaft 40 to rotate, which drives the eccentric wheel 41 to rotate. The eccentric wheel 41 lifts the eccentric wheel connecting plate 42, causing the paper-stopping plate 31 to move upward. The center end of the eccentric wheel 41 rotates away from the eccentric force connecting plate 42, causing the paper-stopping plate 31 to move downward under its own weight. Thus, by adjusting the arrangement height of the paper-stopping plate 31, the distance between it and the central conveyor belt 28 can be adjusted, thereby adapting to the production of paperboards of different thicknesses. In practice, a guide rail is vertically installed on the side plate 30, and a guide rail slider is slidably installed on the guide rail. The baffle plate 31 is fixed on the guide rail slider, which can guide the movement of the baffle plate 31 and ensure that the eccentric wheel connecting plate 42 will not detach from the eccentric wheel 41.

[0021] Furthermore, a rack 44 is fixed to the bottom of the paper feeder 29, and multiple racks 44 of the paper feeder 29 are connected together by a connecting rod 47. A lifting drive shaft 45 is rotatably mounted on the middle conveyor frame 27, and a gear 46 is mounted on the lifting drive shaft 45. The gear 46 meshes with the rack 44. A paper feeder motor 48 is installed on the middle conveyor frame 27. The output shaft of the paper feeder motor 48 is connected to the lifting drive shaft 45. The paper feeder motor 48 drives the lifting drive shaft 45 to rotate, and the lifting drive shaft 45 drives the rack 44 to move through the gear 46. The rack 44 drives the paper feeder 29 to move up and down, so that the paper feeder 29 moves upward to receive the paper feeder output from the paper feed unit 1, and then moves downward to place the paper feeder on the middle conveyor belt 28.

[0022] Example 5 Based on Example 4, such as Figures 1 to 7 As shown, an acceleration wheel mounting frame 10 is fixed at one end of the counting output frame 4 near the middle conveying unit 2. A drive shaft 11 and a driven shaft 12 are spaced apart along the height direction on the acceleration wheel mounting frame 10. The drive shaft 11 is rotatably connected to the acceleration wheel mounting frame 10, and multiple drive sun gears 13 are mounted on the drive shaft 11. The driven shafts 12 are fixed to the acceleration wheel mounting frame 10, and each drive sun gear 13 is correspondingly provided with a driven sun gear 14. A cardboard conveying space is formed between the driven sun gear 14 and the drive sun gear 13. The driven sun gear 14 is rotatably mounted on a swing connecting plate 15. The swing connecting plate 15 is fitted with... The swing connecting plate 15 is fixed to the driven shaft 12 by bolts. The bolts are set on the side wall of the swing connecting plate 15, and the tail of the bolts extends into the swing connecting plate 15 and abuts against the driven shaft 12. The deflection angle of the swing connecting plate 15 can be adjusted by loosening the bolts, thereby adjusting the distance between the driving sun wheel 13 and the driven sun wheel 14 to accommodate the conveying of cardboard of different thicknesses. The specific conveying method is as follows: the driving shaft 11 is driven to rotate by the motor, and the driving shaft 11 drives the driving sun wheel 13 to rotate, thereby conveying the cardboard that enters between the driving sun wheel 13 and the driven sun wheel 14.

[0023] Example 6 Based on Embodiment 5, the paper feeding unit 1 includes a paper feeding frame 16 and an inclined conveyor belt 17. Several inclined conveyor belts 17 are installed at intervals on the paper feeding frame 16 along the conveying direction perpendicular to the paperboard. An output component is provided at the output end of the inclined conveyor belt 17. The output component includes an upper rubber-coated roller 18 and a lower roller shaft 19. Both the upper rubber-coated roller 18 and the lower roller shaft 19 are rotatably mounted on the paper feeding frame 16. A paperboard conveying gap is formed between the upper rubber-coated roller 18 and the lower roller shaft 19. The paperboard output by the stapler and gluer falls onto the inclined conveyor belt 17. The paperboard is fed between the upper rubber-coated roller 18 and the lower roller shaft 19 through the inclined conveyor belt 17. The paperboard is sent out from the paper feeding unit 1 through the cooperation of the upper rubber-coated roller 18 and the lower roller shaft 19. In specific implementation, both the upper rubber-coated roller 18 and the lower roller shaft 19 are driven by a motor.

[0024] Example 7 Based on Example 6, such as Figures 1 to 7As shown, a paperboard sorting mechanism is provided at one end of the paper feeding unit 1 near the middle conveying unit 2. The paperboard sorting mechanism includes a bidirectional threaded screw 20, a guide shaft 21, and two guide plates 22. The bidirectional threaded screw 20 is rotatably connected to the paper feeding frame 16, and the guide shaft 21 is fixed to the paper feeding frame 16. Screw nuts 24 are threaded onto the two opposite threaded sections of the bidirectional threaded screw 20, and the screw nuts 24 are slidably fitted onto the guide shaft 21. The two guide plates 22 are symmetrically fixed onto the two screw nuts 24. Each guide plate 22 includes an upper vertical plate 23, a sorting inclined plate 25, and a lower vertical plate 26. The two ends of the sorting inclined plate 25 are respectively connected to the upper vertical plate 23 and the lower vertical plate 26. The distance between the two upper vertical plates 23 is greater than the width of the paperboard. The width of the cardboard is such that the distance between the two lower vertical plates 26 is equal to the width of the cardboard. The two-way threaded screw 20 is driven by a motor to make the two screw nuts 24 move in opposite directions, thereby adjusting the distance between the two guide plates 22 so that the distance between the two lower vertical plates 26 is equal to the width of the cardboard. Since the distance between the two upper vertical plates 23 is greater than the width of the cardboard, the cardboard can be smoothly output between the two guide plates 22. The cardboard is guided by two sorting inclined plates 25 so that it can fall smoothly between the two lower vertical plates 26, completing the position adjustment of the cardboard and enabling the cardboard to be accurately conveyed into the middle conveying unit 2. The cardboard receiving 29 is located between the two lower vertical plates 26 to receive the cardboard and ensure the accurate conveying of the cardboard.
