Description

Technical Field

[0001] This invention relates to the technical field of elevator grating tube packaging, specifically a large paper tube grating packaging machine. Background Technology

[0002] An elevator light curtain is a light-based safety device for elevator doors, suitable for passenger and freight elevators, protecting passenger safety. Simply put, a light curtain consists of two rods; one end emits n light rays, and the other end receives the light. Mounting these rods onto the two elevator doors creates the typical elevator light curtain. The number of light rays can be selected as needed; modern elevators typically have 64 segments, which is sufficient for most uses.

[0003] The light curtain, also known as a grating, is typically over 2 meters long. During processing, to provide protection, the light curtain needs to be inserted into a large paper tube. Then, foam and a plastic cap are placed into the opening of the large paper tube to seal it. However, the current processing of elevator light curtains suffers from difficulties in feeding the large paper tube and low processing efficiency, so improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a large paper tube grating packaging machine to solve the problems of difficult feeding and low processing efficiency of large paper tubes mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large paper tube lenticular packaging machine, comprising a conveyor table, a conveyor belt for conveying large paper tubes and a motor mounted on the conveyor table to drive the conveyor belt, a feeding device on the right side of the conveyor table and an automatic binding device on the left side of the conveyor table, and, from right to left, a lenticular insertion station, a foam filling station, a plastic cap filling station, and a screw hole drilling station arranged sequentially on the conveyor table, with sensors installed at each of these stations. The feeding device includes a feeding bracket, a lifting bracket inside the feeding bracket, and an inclined temporary mounting platform on the lifting bracket. The temporary mounting platform is equipped with a chain elevator. The temporary mounting platform can transfer large paper tubes to the conveyor belt on the left. A feeding tilting bracket for transferring large paper tubes and a cylinder one for driving the feeding tilting bracket are rotatably connected inside the feeding bracket. The lower end of the feeding tilting bracket is located below the chain elevator, and the chain elevator can transport the large paper tubes transferred from the feeding tilting bracket to the temporary mounting platform. The piston rod of the cylinder one is rotatably connected to the upper end of the feeding tilting bracket. Two sets of cylinder brackets are set above the temporary mounting platform and parallel to the temporary mounting platform. Each set of cylinder brackets is equipped with a cylinder two that limits the large paper tube to the lower end of the temporary mounting platform and a cylinder three that limits the large paper tube to the upper end of the temporary mounting platform.

[0006] Furthermore, in order to achieve the limiting function for large paper tubes of different lengths, two sets of limiting adjustment mechanisms are also provided on the conveyor table to limit the sides of the large paper tubes. Each set of limiting adjustment mechanisms includes a limiting baffle extending along the conveyor belt direction, a motor two fixed on the conveyor table, and two guide rails one fixed on the conveyor table.

The output shaft of the motor three is connected to a pneumatic claw that can clamp one end of a large paper tube. The screw-driving device includes a screw machine bracket, a guide rail three vertically fixed on the screw machine bracket, and a cylinder four located above the screw machine bracket. A second slider is slidably connected on the guide rail three. The piston rod of the cylinder four is connected to the second slider. A second connecting plate is fixed on the second slider. An automatic screw machine is provided on the second connecting plate. A positioning post aligned with the pneumatic claw is also provided on the screw machine bracket.

[0008] Furthermore, in order to achieve automatic foam feeding and further improve work efficiency, a foam vibration feeding mechanism is set up at the foam loading station.

A bracket 2 is connected to the piston rod of the rotary cylinder 1. A cylinder 5 is fixed on the bracket 2. A suction cup 1 is connected to the piston rod of the cylinder 5.

[0009] Furthermore, to facilitate subsequent operations by positioning the large paper tube at its initial position, a set of primary positioning components for the large paper tube is also provided on the right side of the conveyor table. The primary positioning components include a first primary positioning rod located at one end of the large paper tube and a second primary positioning plate located at the other end of the large paper tube. The first primary positioning rod is fixed to the conveyor table by two mounting rods. Two symmetrical guide rail seats are provided on the conveyor table. Two parallel guide rails and a lead screw are provided on the two guide rail seats. A lead screw nut is fitted on the lead screw. The first primary positioning rod is fixed on the lead screw nut seat of the lead screw nut. The lead screw nut seat is also slidably connected between the two guide rails. One end of the lead screw passes through one of the guide rail seats and is connected to a motor.

[0010] Furthermore, to facilitate operation and position the large paper tubes during transmission to prevent swaying and affecting transmission efficiency, and to maintain a certain distance between each large paper tube during transmission to further avoid transmission blockage, the first motor is located on the left side of the transmission table. A rotating shaft is connected to the output shaft of the first motor, and two transmission gears are fixed on the rotating shaft at both ends. A second transmission gear that meshes with the first transmission gear is located on the right side of the transmission table. A transmission chain connects the first and second transmission gears, and one or more triangular positioning grippers are provided on each transmission chain.

[0011] Furthermore, in order to achieve automatic plastic cap loading and further improve work efficiency, a plastic cap vibrating feeding mechanism is set up at the plastic cap loading station. The plastic cap vibrating feeding mechanism includes a second vibrating plate and a bracket three fixed on the transmission table. A rotary cylinder two is fixed on the bracket three. A bracket four is connected to the piston rod of the rotary cylinder two. A cylinder six is ​​fixed on the bracket four. A suction cup two is connected to the piston rod of the cylinder six.

[0012] To improve safety, one or more safety baffles are installed on both the front and rear sides of the feeding bracket. A large paper tube feeding port is installed at the rear of the feeding bracket to insert large paper tubes into the inclined feeding bracket. A safety door for easy maintenance is hinged at the front of the feeding bracket. The cylinder bracket is fixed on the feeding bracket.

[0013] To facilitate the positioning of the large paper tube during processing, two lifting mechanisms are provided at both ends of the large paper tube and capable of lifting both ends of the large paper tube at the grating insertion station.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figures 1-6An embodiment of the present invention provides a large paper tube lenticular packaging machine, comprising a conveyor table 1, a conveyor belt 2 for conveying large paper tubes 70, and a motor 3 mounted on the conveyor table 1 to drive the conveyor belt 2. A feeding device 4 is arranged on the right side of the conveyor table 1, and an automatic binding device 5 is arranged on the left side of the conveyor table 1. From right to left, the conveyor table 1 is arranged with a lenticular insertion station 1-1, a foam filling station 1-2, a plastic cap filling station 1-3, and a screw hole drilling station 1-4. Sensors 68 capable of detecting the arrival of the large paper tube 70 are installed at each of these stations. The feeding device 4 includes a feeding bracket 4-1, a lifting bracket 9 arranged inside the feeding bracket 4-1, and an inclined temporary mounting platform 1 on the lifting bracket 9. 0 and chain elevator 11, the temporary mounting platform 10 can transfer the large paper tube 70 to the conveyor belt 2 on the left. The feeding bracket 4-1 is rotatably connected to the feeding tilt bracket 12 for transferring the large paper tube 70 and the cylinder 13 for driving the feeding tilt bracket 12 to tilt. The lower end of the feeding tilt bracket 12 is located below the chain elevator 11, and the chain elevator 11 can transport the large paper tube 70 transferred from the feeding tilt bracket 12 to the temporary mounting platform 10. The piston rod of the cylinder 13 is rotatably connected to the upper end of the feeding tilt bracket 12. Two sets of cylinder brackets 14 parallel to the temporary mounting platform 10 are arranged above the temporary mounting platform 10. Each set of cylinder brackets 14 is provided with a cylinder 2 15 that limits the large paper tube 70 to the lower end of the temporary mounting platform 10 and a cylinder 3 16 that limits the large paper tube 70 to the upper end of the temporary mounting platform 10. In this embodiment, a rotating seat 12-1 is provided at the high end of the feeding tilting bracket 12, and the piston rod of the cylinder 13 is later rotatably connected to the rotating seat 12-1 through a pin 12-2.

[0038] When the above structure is in operation, multiple large paper tubes 70 are placed inside the feeding tilting bracket 12. Then, the driving cylinder 13 is activated, and the piston rod of cylinder 13 extends to push the high end of the feeding tilting bracket 12 upward, ensuring that the high end of the feeding tilting bracket 12 is higher than the low end. Therefore, the large paper tubes 70 on the feeding tilting bracket 12 can be transferred more smoothly to the chain elevator 11. The chain elevator 11 then transfers the large paper tubes 70 to the temporary mounting platform 10 at the upper end. At this time, in order to ensure that the large paper tubes 70 are transferred to the conveyor belt 2... At this time, there will be no transmission blockage problem. By driving the two sets of cylinders 15 and 16, when the piston rods of the two sets of cylinders 16 extend, they can hold the large paper tube 70 at the top of the temporary mounting platform 10 in place, preventing it from flowing below the temporary mounting platform 10. If the two sets of cylinders 15 at the bottom of the temporary mounting platform 10 are working, when their piston rods extend, they can hold the large paper tube 70 at the bottom of the temporary mounting platform 10 in place. The rod is held in place, preventing the large paper tube 70 from flowing onto the lower conveyor belt 2. Only when cylinder two 15 retracts can the large paper tube 70 at the lower part of the temporary mounting platform 10 flow onto the lower conveyor belt 2. Then, cylinder two 15 is driven to work, its piston rod extends, and then the piston rod of cylinder three 16 is driven to retract, causing the large paper tube 70 at the higher part of the temporary mounting platform 10 to fall to the lower part of the temporary mounting platform 10, where it is stopped by cylinder two 15. At the same time, the piston rod of cylinder three 16 at the higher part of the temporary mounting platform 10 continues to extend, ensuring that the chain is lifted. The large paper tube 70 conveyed by machine 11 is blocked, and the operation above continues. This ultimately avoids the problem of the conveyor belt 2 being blocked due to excessive material feeding at one time during the feeding process. Therefore, this structure can avoid the problem of the conveyor belt being blocked due to excessive material feeding during the feeding process. Moreover, the whole operation is automatic and fast, simple to operate, and improves work efficiency. It should be noted that the specific structure of how the chain elevator 11 transmits the large paper tube 70 below to the upper part is conventional technology in this field, so it will not be described in detail.

[0039] like Figure 7-8As shown, furthermore, in order to achieve the limiting effect on large paper tubes 70 of different lengths, two sets of limiting adjustment mechanisms 17 are also provided on the conveyor table 1 to limit the sides of the large paper tubes 70. Each set of limiting adjustment mechanisms 17 includes a limiting baffle 18 extending along the conveying direction of the conveyor belt 2, a motor 19 fixed on the conveyor table 1, and two guide rails 20 fixed on the conveyor table 1. The extending direction of the guide rails 20 is consistent with the length direction of the large paper tubes 70. A positioning plate 21 is slidably connected between the two guide rails 20. The lower part of the positioning plate 21 is slidably connected to the guide rails 20 through a first sliding block 22. The limiting baffle 18 is fixed on the positioning plate 21. The output shaft of the motor 19 is connected to a transmission wheel 23. The transmission wheel 23 is connected to the transmission belt 2. The positioning plate 21 is connected to the transmission belt 25 via a connecting seat 26, and is equipped with a second transmission wheel 24. This structure can limit the movement of large paper tubes 70 of different lengths. For easy movement, the second motor 19 is fixed to the transmission table 1 via a mounting base 19-1. The mounting base 19-1 is also equipped with a guide rail. The first transmission wheel 23 is rotatably connected to one end of the mounting base 19-1, and the second transmission wheel 24 is rotatably connected to the other end of the mounting base 19-1. The output shaft of the second motor 19 passes through one side of the mounting base 19-1 and is connected to the rotation shaft at the center of the first transmission wheel 23. A slider is provided below the connecting seat 26 and is slidably connected to the guide rail on the mounting base 19-1, thereby improving the sliding effect.

[0040] like Figure 9-11As shown, further, in order to achieve the function of automatic screw driving and further improve work efficiency, an automatic screw-driving mechanism 8 is set on the screw-driving hole station 1-4. The automatic screw-driving mechanism 8 includes a positioning device 73 located at one end of the large paper tube 70 and a screw-driving device 28 located at the other end of the large paper tube 70. The positioning device 73 includes a positioning bracket 27, on which two guide rails 29 are set. A lead screw 30 is set between the guide rails 29. A lead screw motor 72 for driving the lead screw 30 to rotate is also set on the positioning bracket 27. A lead screw nut 31 is fitted on the lead screw 30. A lead screw nut seat 32 of the lead screw nut 31 is connected to a screw nut seat 32. A fixed base 33 is provided, and a fixed bracket 34 is provided above the fixed base 33. A motor 35 is provided on one side of the fixed bracket 34. The output shaft of the motor 35 is connected to a pneumatic claw 36 that can clamp one end of the large paper tube 70. The screw-driving device 28 includes a screw-driving bracket 28-1, a guide rail 28-2 vertically fixed on the screw-driving bracket 28-1, and a cylinder 28-3 located above the screw-driving bracket 28-1. A second slider 28-4 is slidably connected on the guide rail 28-2. The piston rod of the cylinder 28-3 is connected to the second slider 28-4. A second connecting plate 28-5 is fixed on the second slider 28-4. An automatic screwdriver 28-6 is installed on the second connecting plate 28-5. A positioning post 28-7 aligned with the pneumatic claw 36 is also installed on the screwdriver bracket 28-1. When this structure is working, after receiving a signal through the sensor 68 at this station, it controls the lead screw motor 72 to rotate, causing the lead screw 30 to rotate. This causes the lead screw nut 31 to move horizontally on the lead screw 30, ultimately changing the distance between the pneumatic claw 36 and the positioning post 28-7. This ensures that the pneumatic claw 36 pushes the large paper tube 70 at this station towards the positioning post 28-7, ensuring that the positioning post 28-7 is inserted into one end of the large paper tube 70. This ensures that the plastic cap inside the large paper tube 70 is pressed against one end of the large paper tube 70. The other end of the paper tube 70 is clamped by the pneumatic gripper 36. Then, the screw-driving head of the automatic screwdriver 28-6 above is driven to press down and drive the screw from the side wall of one end of the paper tube 70 into the inner plastic cover. After driving one screw, the drive motor 35 drives the clamped paper tube 70 to rotate to the next position and continue driving screws until several screws are driven around the side of one end of the paper tube 70. Therefore, the above structure improves work efficiency and makes it easy to clamp the two ends of the paper tube 70 of different lengths. Finally, it is convenient to drive screws on paper tubes of different lengths, thus improving practicality.

[0041] like Figure 12 , 14As shown in Figure 15, furthermore, in order to achieve automatic foam feeding and further improve work efficiency, a foam vibration feeding mechanism 6 is set up at the foam loading station 1-2. The foam vibration feeding mechanism 6 includes a first vibrating plate 37 and a bracket 38 fixed on the transmission table 1. A rotary cylinder 39 is fixed on the bracket 38. A second bracket 40 is connected to the piston rod of the rotary cylinder 39. A fifth cylinder 41 is fixed on the bracket 40. A suction cup 42 is connected to the piston rod of the fifth cylinder 41. During operation, when the sensor 68 of this station receives a signal, it controls the first vibrating plate 37 to work through the vibration transmission channel 37 on the first vibrating plate 37. 1. The foam is transferred from the first vibrating plate 37 to the foam placement channel 37-2 on the transfer table 1. At this time, the rotary cylinder 39 is driven to rotate 90 degrees, causing cylinder 41 to change from a horizontal to a vertical position. Cylinder 41 first drives suction cup 42 to move down and suck up the foam in the foam placement channel 37-2. Then, cylinder 41 retracts, ensuring that suction cup 42 moves up and is reset to a horizontal position by the rotary cylinder 39. Then, cylinder 41 is driven to retract suction cup 42 until the foam is inserted into the large paper tube 70 at this station. Finally, cylinder 41 retracts, completing the automatic foam feeding operation. In this embodiment, the piston rod of cylinder 41 is connected to the suction cup rod 42-1 on suction cup 42 via a seventh bracket 41-1. The connection structure between suction cup 62 and cylinder 61 is also such that they are connected via a seventh bracket.

[0042] like Figure 12 , 13As shown in Figure 16, furthermore, in order to achieve primary positioning of the large paper tube 70 and facilitate subsequent operations, a set of primary positioning components 43 for the large paper tube is also provided on the right side of the transmission table 1. The primary positioning components include a first primary positioning rod 44 located at one end of the large paper tube 70 and a second primary positioning plate 45 located at the other end of the large paper tube 70. The first primary positioning rod 44 is fixed to the transmission table 1 by two mounting rods 46. Two symmetrical guide rail seats 47 are provided on the transmission table 1. Two parallel guide rails 48 and a lead screw 49 are provided on the two guide rail seats 47. A lead screw nut 50 is fitted on the lead screw nut 50. The first primary positioning rod 44 is fixed on the lead screw nut seat 51 of the lead screw nut 50. The lead screw nut seat 51 is also slidably connected to the two guide rails 48. Between the guide rails 48, one end of the lead screw 49 passes through one of the guide rail seats 47 and is connected to the motor 69. This structure is designed so that when the large paper tube 70 is transferred from the temporary mounting table 10 to the conveyor belt 2, the two first primary positioning rods 44 and the second primary positioning plate 45 on the far right of the conveyor table 1 cooperate to perform primary transmission position positioning of the large paper tube 70. When the large paper tube 70 reaches the large paper tube primary positioning component 43, the sensor 68 at that position senses the arrival of the large paper tube 70. At this time, the drive motor 69 works, driving the lead screw 49 to rotate, and simultaneously driving the lead screw nut 50 to rotate on the lead screw 49 to move horizontally. Finally, the distance between the first primary positioning rod 44 and the second primary positioning plate 45 is adjusted, and the large paper tube 70 at this station is finally positioned. After positioning is completed, it flows to the next station.

[0043] like Figure 12As shown, furthermore, to facilitate operation and position the large paper tubes 70 during transmission to avoid swaying and affecting the transmission effect, and to maintain a certain distance between each large paper tube 70 during transmission to further avoid transmission blockage, the motor 3 is located on the left side of the transmission table 1. A rotating shaft 52 is connected to the output shaft of the motor 3. Two transmission gears 53 are fixed on the rotating shaft 52 at both ends. A transmission gear 54 that cooperates with the transmission gears 53 is provided on the right side of the transmission table 1. A transmission chain 55 connects the corresponding transmission gears 53 and transmission gear 54. Each transmission chain 55 is provided with one or more triangular positioning grippers 56. When the motor 3 operates, it drives the rotating shaft 52 to rotate. The rotating shaft 52 drives two transmission gears 53 to rotate. The transmission gears 53, in conjunction with the transmission gear 54 on the other side, synchronously drive the two transmission chains 55 to rotate. This allows the large paper tube 70 above to be slowly moved from the right to the left, ultimately achieving assembly line transmission. Triangular positioning grippers 56 are set on the transmission chains 55 to ensure that there is a gap between each large paper tube 70 during transmission. This ensures that when the large paper tube 70 arrives at each station and is processed, the transmission chain 55 below is still running, ensuring a certain time difference. This prevents the processed large paper tube 70 from being transferred to the next station, which would ultimately affect the processing efficiency and scrap rate of the entire assembly line.

[0044] like Figure 14 As shown, furthermore, in order to achieve automatic plastic cap feeding and improve work efficiency, a plastic cap vibrating feeding mechanism 7 is set up at the plastic cap loading station 1-3. The plastic cap vibrating feeding mechanism 7 includes a second vibrating plate 57 and a bracket 3 58 fixed on the transmission table 1. A rotary cylinder 2 59 is fixed on the bracket 3 58. A bracket 4 60 is connected to the piston rod of the rotary cylinder 2 59. A cylinder 61 is fixed on the bracket 4 60. A suction cup 2 62 is connected to the piston rod of the cylinder 61. The structure of the automatic plastic cap feeding is the same as that of the foam vibrating feeding mechanism 6 mentioned above. The only difference is that the first vibrating plate 37 in the foam vibrating feeding mechanism 6 stores foam, while the second vibrating plate 57 stores plastic caps. Therefore, the specific feeding working principle of the plastic cap vibrating feeding mechanism 7 can be referred to the foam vibrating feeding mechanism 6 mentioned above, which ultimately achieves automatic plastic cap feeding and further improves work efficiency.

[0045] To improve safety, one or more safety baffles 63 are provided on both the front and rear sides of the feeding bracket 4-1. A large paper tube feeding port 64 is provided at the rear of the feeding bracket 4-1, which allows the large paper tube 70 to be inserted into the feeding inclined bracket 12. A safety door 65 is hinged at the front of the feeding bracket 4-1 for easy maintenance. The cylinder bracket 14 is fixed to the feeding bracket 4-1. The safety baffles 63 improve safety, and the safety door 65 facilitates the opening and maintenance of the equipment inside the feeding bracket 4-1.
