Description

Technical Field

[0001] This utility model relates to the field of cup production technology, specifically a positioning and capping machine. Background Technology

[0002] The manufacturing process of cups involves a series of processing steps, including pre-hot stamping screening, hot stamping, post-hot stamping screening, stacking, and packaging. If cup production is carried out manually, that is, by relying on people to move and package the cups between workstations, the production efficiency of cups will be greatly reduced. If cups are inspected manually, the yield rate of cups will be greatly reduced. Therefore, the realization of automated cup production has become a market trend, and thus automated cup production lines have emerged. In the automated production of plastic or metal cups, depending on different production needs, it is sometimes necessary to affix labels to the cup lids. In automated production lines, cups are mostly transported by conveyor belts. Therefore, during the lid affixing process, the cups need to be positioned first to avoid label affixing deviations and improve production quality. In the prior art, to avoid cup position shifts that could lead to label affixing failures or positional deviations, a set of calibration robots is often added. However, while using robots to position and calibrate the cups can solve the positioning problem, it also drastically increases production costs and requires dedicated personnel for maintenance, which is not conducive to the development of small and medium-sized enterprises and has certain limitations. Therefore, this utility model proposes a simplified positioning and capping machine with optimized structure. Utility Model Content

[0003] The purpose of this invention is to provide a positioning and capping machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning and capping machine, comprising a worktable, with support legs fixedly installed at the four corners of the lower surface of the worktable, a conveyor belt installed on the worktable, grooves provided on both sides of the conveyor belt, and positioning mechanisms fixedly installed in two of the grooves, the two positioning mechanisms being arranged opposite to each other, the positioning mechanism further comprising a mounting frame, the mounting frame being installed in the groove, a positioning cylinder being fixedly installed on the mounting frame, a telescopic piston rod being provided at the output end of the positioning cylinder, a clamping plate being fixedly installed at the top end of the piston rod, a plurality of evenly distributed buffer springs being fixedly installed on the outer surface of the clamping plate, a rubber pad being connected to the outer wall of the top end of the plurality of buffer springs, and a U-shaped frame being installed between the two sets of positioning mechanisms, the U-shaped frame being installed across the side wall of the conveyor belt.

[0005] Preferably, a conveyor motor for driving the transmission is installed at one end of the conveyor belt, and the outer surface of the conveyor belt is a smooth surface.

[0006] Preferably, a cover-applying cylinder is fixedly installed at the center of the upper surface of the U-shaped frame, and a fixing box is fixedly installed at the bottom end of the piston rod of the cover-applying cylinder through a fixing plate.

[0007] Preferably, a primary fixing block is fixedly installed inside both sides of the fixing box. The primary fixing block has a hollow structure design, and a secondary spring is fixedly installed inside the primary fixing block.

[0008] Preferably, a connecting block is fixedly installed at the bottom end of the secondary spring, and the connecting block is slidably connected to the primary fixing block for limiting.

[0009] Preferably, a connecting post is fixedly installed on the lower surface of the connecting block, the connecting post penetrates the lower surface of the primary fixing block, and the connecting post is slidably connected to the primary fixing block.

[0010] Preferably, a suction cup is provided below the fixed box, and a negative pressure suction nozzle is installed on the lower surface of the suction cup.

[0011] Preferably, a secondary fixing block is fixedly installed on both sides of the upper surface of the suction cup, and the secondary fixing block is fixedly connected to the connecting column.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a positioning structure to push cups on a conveyor belt to the designated capping area, resulting in better capping positioning, improved accuracy, and reduced deviations. This significantly enhances the accuracy of cup capping. Compared to robotic arm positioning, this invention uses two sets of cylinders for relative drive positioning, effectively reducing production costs. Furthermore, its simple overall structure and easy maintenance make it suitable for practical application. Meanwhile, because a buffer spring is installed between the rubber pad and the clamping plate, the buffer spring can play a certain role in buffering the cup when the two positioning mechanisms abut and clamp it, reducing the impact force when the piston rod extends, and effectively clamping and buffering the positioning cup. In actual use, the positioning mechanism has the dual function of pushing and positioning as well as fixing and clamping.

[0013] This invention incorporates a spring buffer structure between the fixing plate and the suction cup. When the suction cup is pressed down to attach the cup, the suction cup can compress the secondary spring at the top through the secondary fixing block. This secondary spring structure provides spring protection when the suction cup is pressed down, better cushioning the cup during the pressing process and improving the spring buffering effect. This, in turn, increases the yield rate when attaching the cup lid. Attached Figure Description

[0019] Please see Figure 1-5 The present invention provides an embodiment of a positioning capping machine, which includes a workbench 1, with support legs 2 fixedly installed at the four corners of the lower surface of the workbench 1, a conveyor belt 3 installed on the workbench 1, and a conveyor motor 4 for driving the transmission of the conveyor belt 3 installed at one end, so as to ensure the normal conveying operation of the conveyor belt 3. The outer surface of the conveyor belt 3 is a smooth surface with a low coefficient of friction, so as to avoid the phenomenon of friction and tipping of the cup when positioning and pushing the material. For further details, please refer to the appendix to the instruction manual. Figure 2 as well as Figure 3 As shown, grooves 9 are provided on both sides of the conveyor belt 3. Positioning mechanisms 8 are fixedly installed in both grooves 9. The two positioning mechanisms 8 are arranged opposite to each other. The positioning mechanism 8 also includes a mounting frame 81. The mounting frame 81 is installed in the groove 9. A positioning cylinder 82 is fixedly installed on the mounting frame 81. A telescopic piston rod is provided at the output end of the positioning cylinder 82. A clamping plate 83 is fixedly installed at the top of the piston rod. Several evenly distributed buffer springs 84 are fixedly installed on the outer surface of the clamping plate 83. A rubber pad 85 is connected to the outer wall of the top of several buffer springs 84. Based on the above structure, when the cup to be covered is conveyed by the conveyor belt 3 to the two positioning mechanisms 8, the conveyor belt 3 stops working. Then, the piston rod of the positioning cylinder 82 can be driven to extend to a preset length. When the piston rod of the two positioning cylinders 82 extends, it can push the cup on the conveyor belt 3 through the rubber pad 85, pushing the cup to the middle position of the conveyor belt 3, so that the cup is in the middle position of the conveyor belt 3, and the middle positioning of the cup is completed. When the two positioning mechanisms 8 push the cup to the middle position of the conveyor belt 3, the buffer spring 84 between the rubber pad 85 and the clamping plate 83 plays a certain role in buffering the cup when the two positioning mechanisms 8 clamp it, reducing the impact force when the piston rod extends, and effectively clamping and buffering the positioning cup. In actual use, the positioning mechanism 8 has the dual function of pushing and positioning as well as fixing and clamping. Through the design and use of the positioning structure 8, the cup on the conveyor belt 3 can be pushed to the designated capping area in the middle, thus achieving a better capping positioning effect, improving the accuracy of the capping position, and avoiding capping position deviation. At the same time, compared with the positioning of a robotic arm, this utility model uses two sets of cylinders for relative drive positioning, which can effectively reduce production costs. Moreover, the overall structure is simple, easy to maintain, and suitable for implementation.

[0020] In this embodiment, in order to sense the cup, an infrared sensor for infrared sensing can be installed on the outer surface of the mounting bracket 81. After the infrared sensor senses the cup, it can transmit the signal to the production line control system, thereby controlling the conveyor belt 3 and the positioning mechanism to perform automated work and complete subsequent actions.

[0021] In this embodiment, a U-shaped frame 5 is installed between the two sets of positioning mechanisms 8. The U-shaped frame 5 is installed across the side wall of the conveyor belt 3. In order to ensure normal capping processing, a capping cylinder 6 is fixedly installed at the center of the upper surface of the U-shaped frame 5. The bottom end of the piston rod of the capping cylinder 6 is fixedly installed with a fixed box 10 through a fixed plate 7. A primary fixing block 12 is fixedly installed inside both sides of the fixed box 10. The interior of the primary fixing block 12 is hollow. A secondary spring 13 is fixedly installed inside the primary fixing block 12. A connecting block 14 is fixedly installed at the bottom end of the secondary spring 13. The connecting block 14 is limited and slidably connected to the primary fixing block 12. Furthermore, a connecting post 15 is fixedly installed on the lower surface of the connecting block 14. The connecting post 15 penetrates the lower surface of the first-level fixing block 12 and is slidably connected to the first-level fixing block 12. A suction cup 11 is provided below the fixing box 10. A negative pressure suction nozzle is installed on the lower surface of the suction cup 11. The label with the cover can be adsorbed by the negative pressure suction nozzle. Secondary fixing blocks 16 are fixedly installed on both sides of the upper surface of the suction cup 11. The secondary fixing blocks 16 are fixedly connected to the connecting post 15. Based on the above structure, when the two sets of positioning mechanisms 8 push the cup to the middle position of the conveyor belt 3 and clamp it, the cup lid is positioned directly below the negative pressure suction nozzle. Then, the operator places the label on the negative pressure suction nozzle, which performs negative pressure adsorption. Afterwards, the set capping cylinder 6 drives the suction cup 11 to descend through its piston rod. When the suction cup 11 descends, it can attach the label on the negative pressure suction nozzle to the cup lid below, thus completing the capping process of the cup and ensuring normal use.

[0022] This utility model incorporates a spring buffer structure between the fixing plate 7 and the suction cup 11. When the suction cup 11 is pressed down to attach the cup, the suction cup 11 can compress the secondary spring 13 at the top through the secondary fixing block 16. The structure of the secondary spring 13 provides a certain spring protection when the suction cup 11 is pressed down, thus better buffering the cup when it is pressed down and improving the spring buffering effect. This, in turn, increases the yield rate when attaching the cup lid.

[0023] Working principle: When the positioning and capping machine of this utility model is in operation, an infrared sensor for infrared sensing can be installed on the outer surface of the mounting frame 81. After the infrared sensor senses the cup, it can transmit the signal to the control system of the production line, thereby controlling the conveyor belt 3 and the positioning mechanism to perform automated work and complete subsequent actions. When the cup enters the conveyor belt 3 of this invention from the external conveying structure, the infrared sensor can detect the cup after the cup is conveyed to the designated position. When the infrared sensor detects the cup, the cup is exactly between the two positioning mechanisms 8. At this time, the infrared sensor transmits the sensing signal to the production line's main control system, thereby controlling the conveyor belt 3 to stop working. Then, the piston rod of the positioning cylinder 82 can be driven to extend to a preset length. When the piston rod of the two positioning cylinders 82 extends, it can push the cup on the conveyor belt 3 through the rubber pad 85, pushing the cup to the middle position of the conveyor belt 3, so that the cup is in the middle position of the conveyor belt 3, completing the middle positioning process of the cup. When the two positioning mechanisms 8 push the cup to the middle position of the conveyor belt 3, the two clamping plates 83 can clamp the cup through the rubber pads 85 to prevent it from moving. After the two sets of positioning mechanisms 8 push the cup to the middle position of the conveyor belt 3 and clamp it, the cup lid is placed directly below the negative pressure suction nozzle. Then, the operator places the cap label on the negative pressure suction nozzle and performs negative pressure adsorption. Afterwards, the set cap-applying cylinder 6 can drive the suction cup 11 to descend through its piston rod. When the suction cup 11 descends, it can attach the label on the negative pressure suction nozzle to the cup lid below, thus completing the cap-applying process of the cup and ensuring normal use. After the lid is applied, the positioning mechanism 8 and the lid-applying cylinder 6 are driven to reset, and the conveyor belt 3 continues to convey the contents. After a new cup is detected, the above steps are repeated to complete the cyclic processing of this utility model.

[0024] Because a buffer spring 84 is provided between the rubber pad 85 and the clamping plate 83, the buffer spring 84 can play a certain spring buffering role when the two positioning mechanisms 8 clamp the cup, reducing the impact force when the piston rod extends, and effectively clamping and buffering the positioning cup. In actual use, the positioning mechanism 8 has the dual function of pushing and positioning and fixing and clamping. Through the design and use of the positioning structure 8, the cup on the conveyor belt 3 can be pushed to the designated capping area in the middle, thus achieving a better capping positioning effect, improving the accuracy of the capping position, and avoiding capping position deviation. At the same time, compared with the positioning of a robotic arm, this utility model can effectively reduce production costs by using two sets of cylinders for relative drive positioning. Moreover, the overall structure is simple, easy to maintain, and suitable for implementation. This utility model incorporates a spring buffer structure between the fixing plate 7 and the suction cup 11. When the suction cup 11 is pressed down to attach the cup, the suction cup 11 can compress the secondary spring 13 at the top through the secondary fixing block 16. The structure of the secondary spring 13 provides a certain spring protection when the suction cup 11 is pressed down, thus better buffering the cup when it is pressed down and improving the spring buffering effect. This, in turn, increases the yield rate when attaching the cup lid.
