[0002] A tinplate can is a metal container made of tinplate (i.e., tin-coated thin steel sheet). Due to its corrosion resistance, strength, and sealability, tinplate cans are widely used for packaging products such as food, beverages, cosmetics, and chemicals. When producing (sealing) products packaged in tinplate cans, the can body and the can lid need to be assembled.
[0003] Currently, when the can seamer equipment has a can body without a can lid (a can without a lid) or a can lid without a can body (a lid without a can), the machine will also perform the curling actions of the can body and the can lid according to the pre-set program, forcibly deforming the can body or the can lid, exacerbating the wear of the curling head and the curling wheel, increasing the loss of the can body, the can lid, and the filling material. At the same time, manual shutdown is required to open the head bin of the can seamer to clean the waste can body and the waste can lid, causing the production line to stop and affecting production efficiency. Content of the Utility Model

A conveyor belt is rotatably connected inside the machine body. A can body is arranged at the upper end of the conveyor belt. A second infrared sensor is fixedly connected to the upper end of the machine body. The second infrared sensor and the can body are on the same horizontal line. Both the first infrared sensor and the second infrared sensor are adapted to the control box. A feeding mechanism is fixedly connected inside the machine body.

[0009] Preferably: A slider is slidably connected inside the machine body.
[0010] Preferably: A first spring is fixedly connected inside the slider. A push block is fixedly connected to the upper end of the first spring.
[0011] Preferably: A mounting seat is fixedly connected to the upper end of the machine body. A second positioning column is fixedly connected to the upper end of the mounting seat.

[0013] Preferably: Four second springs are sleeved inside the mounting seat. Rubber pads are sleeved on the outer surfaces of the four buffer plates.
[0014] (III) Beneficial effects
[0015] First, by setting the first infrared sensor and the second infrared sensor to detect the operation state of the equipment, the loss rate of the can lid body and the can body can be reduced, the wear of the curling head and the curling wheel of the machine body can be reduced, and the continuous operation time of the production line can be increased, achieving the purpose of cost reduction, efficiency improvement and output increase.
[0016] Second, when feeding the can lid body, place the can lid body in the second positioning column.

When the can lid body passes through the buffer plates or the weight of the can lid body is not enough to push the buffer plates to slide, the second spring drives the four buffer plates to slide back to the center. After the can lid body passes through the buffer plates, it slides down along the first positioning column to the bottom and is stacked on the remaining can lid bodies. By setting the sliding buffer plates on the first positioning column to buffer the rapidly falling can lid body, it is possible to avoid damage caused by the collision of two can lid bodies during the sliding process, which is beneficial to improving the assembly quality.

Detailed Description of the Preferred Embodiment
[0023] In the embodiment of the present application, by providing a lid-canning linkage protection device for tinplate cans, it effectively solves the problem that when the current can seaming machine has a can body without a can lid (no lid for the can) or a can lid without a can body (no can for the lid), the machine will also perform the curling actions of the can body and the can lid according to the pre-set program, forcibly deforming the can body or the can lid, aggravating the wear of the curling head and the curling wheel, increasing the loss of the can body, the can lid and the filling, and at the same time, manual shutdown is required to open the head bin of the can seaming machine to clean the waste can body and the waste can lid, causing the production line to stop and affecting the production efficiency. By setting the first infrared sensor and the second infrared sensor to detect the operating state of the equipment, the loss rate of the can lid body and the can body main body can be reduced, the wear of the curling head and the curling wheel of the machine main body can be reduced, the continuous operation time of the production line can be increased, and the purpose of cost reduction, efficiency improvement and production increase can be achieved.
[0024] Embodiment
[0025] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that when the current can seaming machine has a can body without a can lid (a can without a lid) or a can lid without a can body (a lid without a can), the machine will also perform the seaming action of the can body and the can lid according to the pre-set program, forcibly deforming the can body or the can lid, aggravating the wear of the seaming head and the seaming wheel of the can seaming machine, increasing the loss of the can body, the can lid and the filling material. At the same time, it is also necessary to manually stop the machine and open the head bin of the can seaming machine to clean the waste can body and the waste can lid, resulting in the suspension of the production line and affecting the production efficiency. The general idea is as follows: A lid-can linkage protection device for tinplate can seaming includes a machine main body 11. A control box 12 is fixedly connected to the outer surface of the machine main body 11. A first positioning column 13 is fixedly connected to the upper end of the machine main body 11. A can lid body 14 is arranged inside the first positioning column 13. A first infrared sensor 15 is fixedly connected to the upper end of the machine main body 11. The first infrared sensor 15 and the can lid body 14 are on the same horizontal line. A conveyor belt 16 is rotatably connected inside the machine main body 11. A can body 17 is arranged at the upper end of the conveyor belt 16. A second infrared sensor 18 is fixedly connected to the upper end of the machine main body 11. The second infrared sensor 18 and the can body 17 are on the same horizontal line. Both the first infrared sensor 15 and the second infrared sensor 18 are adapted to the control box 12. When multiple can lid bodies 14 are successively pushed out for feeding work, the first infrared sensor 15 detects the height of the first positioning column 13. When the number of the first positioning columns 13 is higher than the detection position of the first infrared sensor 15, the first positioning column 13 determines that the current number of the can lid bodies 14 is in a sufficient state. When the first positioning column 13 is consumed below the detection position of the first infrared sensor 15, the first infrared sensor 15 determines that the current state is a lack of the first positioning column 13. Both the first infrared sensor 15 and the second infrared sensor 18 are connected to the control box 12. A feedback signal is sent to the control box 12 through the first infrared sensor 15. (The control box 12 is composed of a signal processing module, an air circuit breaker and an alarm buzzer). After receiving the signal of lack of lids, the signal processing module triggers the air circuit breaker to stop the machine, stops the running state of the machine main body 11, and sends an instruction to the alarm buzzer to play an alarm sound to remind the staff to add the can lid body 14. When the first infrared sensor 15 senses again that the number of the can lid bodies 14 is higher than the set inventory safety value, the shutdown protection state is released and the operation of the machine main body 11 is restored. When the second infrared sensor 18 located on the conveyor belt 16 senses that there is no can body 17 passing through for a long time, it transmits the signal of no can body 17 to the signal processing module. After receiving the signal, the signal processing module stops the lid feeding action of pushing the can lid body 14. When the second infrared sensor 18 senses again that there is a can body 17 passing through, it resumes to the lid feeding action. By setting the first infrared sensor 15 and the second infrared sensor 18 to detect the operation state of the equipment, the loss rate of the can lid body 14 and the can body 17 can be reduced, the wear of the seaming head and the seaming wheel of the machine main body 11 can be reduced, and the continuous running time of the production line can be increased.To achieve the purpose of cost reduction, efficiency improvement and output increase.
[0026] Inside the machine body 11, a feeding mechanism is fixedly connected. The feeding mechanism includes a cylinder 19, and the cylinder 19 is fixedly connected inside the machine body 11. A slider 21 is slidably connected inside the machine body 11. The slider 21 is sleeved inside the cylinder 19. A first spring 22 is fixedly connected inside the slider 21. The upper end of the first spring 22 is fixedly connected with a push block 23. Place the tinplate cans and the can body 17 on the first positioning post 13 and the conveyor belt 16 respectively. Start the conveyor belt 16 and the cylinder 19. The can body 17 is conveyed into the machine body 11 through the conveyor belt 16. The cylinder 19 outputs an axial force to push the slider 21 to slide towards one end of the machine body 11. During the sliding process of the slider 21, the flatter side of the push block 23 pushes a can lid body 14 to slide into the machine body 11. The machine body 11 assembles the can lid body 14 and the can body 17. When the output shaft of the cylinder 19 retracts and resets, the can lid body 14 contacts the inclined surface of the push block 23, and the can lid body 14 squeezes the push block 23 to slide down and contract. When the push block 23 passes through the can lid body 14, the first spring 22 drives the push block 23 to extend and reset to the initial position to prepare for the next operation.
[0027] At the upper end of the machine body 11, a mounting seat 24 is fixedly connected. At the upper end of the mounting seat 24, a second positioning post 25 is fixedly connected. Four buffer plates 26 are slidably connected inside the mounting seat 24. The four buffer plates 26 are all on the same vertical line as the can lid body 14. Four second springs 27 are sleeved inside the mounting seat 24. The four second springs 27 are respectively sleeved on the outer surfaces of the four buffer plates 26. Rubber pads 28 are sleeved on the outer surfaces of the four buffer plates 26. When loading the can lid body 14, place the can lid body 14 in the second positioning post 25. The second positioning post 25 limits the periphery of the can lid body 14 to ensure the placement position of the can lid body 14 and achieve the effect of rapid positioning. The can lid body 14 slides down along the second positioning post 25 and contacts the rubber pad 28 during the sliding process. The can lid body 14 squeezes the four buffer plates 26 to slide outwards by its own weight. When the can lid body 14 passes through the buffer plates 26 or the weight of the can lid body 14 is not enough to push the buffer plates 26 to slide, the four second springs 27 drive the four buffer plates 26 to slide towards the center and reset. After the can lid body 14 passes through the buffer plates 26, it slides down along the first positioning post 13 to the bottom and is stacked on the remaining can lid bodies 14. By arranging the sliding buffer plates 26 on the first positioning post 13 to buffer the rapidly falling can lid body 14, it is avoided that the two can lid bodies 14 collide and cause damage during the sliding process, which is beneficial to improving the assembly quality.
[0028] Aiming at the problems existing in the prior art, the utility model provides a lid-tank linkage protection device for sealing tinplate cans. By setting the first infrared sensor 15 and the second infrared sensor 18 to detect the operation state of the equipment, the loss rate of the can lid body 14 and the can body 17 can be reduced, the wear of the seaming head and the seaming wheel of the machine main body 11 can be reduced, and the continuous operation time of the production line can be increased, so as to achieve the purpose of cost reduction, efficiency improvement and output increase.
[0029] Working principle:
[0030] First step, place the components of the tinplate can and the can body 17 in the first positioning post 13 and on the conveyor belt 16 respectively with the first positioning post 13. Start the conveyor belt 16 and the cylinder 19. The can body 17 is conveyed into the machine main body 11 through the conveyor belt 16. The output shaft of the cylinder 19 pushes the slider 21 to slide towards one end of the machine main body 11 axially. During the sliding process of the slider 21, the flatter side of the push block 23 pushes a can lid body 14 to slide into the machine main body 11. The machine main body 11 assembles the can lid body 14 and the can body 17. When the output shaft of the cylinder 19 retracts and resets, the can lid body 14 contacts the inclined surface of the push block 23, and the can lid body 14 squeezes the push block 23 to slide down and contract. When the push block 23 passes through the can lid body 14, the first spring 22 drives the push block 23 to extend and reset to the initial position to prepare for the next work.
[0031] Step 2: When multiple lid bodies 14 are successively pushed out for feeding, the first infrared sensor 15 detects the height of the first positioning post 13. (The first infrared sensor 15 and the second infrared sensor 18 detect objects based on the principle of infrared emission and reception. They emit infrared light and receive the reflected light to determine the position and distance of the object, and have the function of emitting infrared rays to detect whether there is an object at the current height). When the number of the first positioning posts 13 is higher than the detection position of the first infrared sensor 15, the first positioning post 13 determines that the current number of lid bodies 14 is sufficient. When the first positioning post 13 is consumed below the detection position of the first infrared sensor 15, the first infrared sensor 15 determines that there is a lack of the first positioning post 13. Both the first infrared sensor 15 and the second infrared sensor 18 are connected to the control box 12. A feedback signal is sent to the control box 12 through the first infrared sensor 15. (The control box 12 consists of a signal processing module, an air circuit breaker, and an alarm buzzer). After receiving the signal of missing lids, the signal processing module triggers the air circuit breaker to stop the machine, halting the operating state of the machine body 11, and sends an instruction to the alarm buzzer to play an alarm sound to remind the staff to add the lid bodies 14. When the first infrared sensor 15 senses again that the number of lid bodies 14 is higher than the set inventory safety value, the shutdown protection state is lifted, and the operation of the machine body 11 is restored. When the second infrared sensor 18 located on the conveyor belt 16 senses that there is no can body 17 passing by for a long time, it transmits the signal of no can body 17 to the signal processing module. After receiving the signal, the signal processing module stops the lid feeding action of pushing the lid bodies 14. When the second infrared sensor 18 senses again that there is a can body 17 passing by, it resumes the lid feeding action. By setting the first infrared sensor 15 and the second infrared sensor 18 to detect the operating state of the equipment, the loss rate of the lid bodies 14 and the can bodies 17 can be reduced, the wear of the seaming head and seaming wheels of the machine body 11 can be reduced, the continuous operation time of the production line can be increased, and the purpose of cost reduction, efficiency improvement, and production increase can be achieved. When feeding the lid bodies 14, the lid bodies 14 are placed in the second positioning posts 25. The second positioning posts 25 limit the periphery of the lid bodies 14 to ensure the placement position of the lid bodies 14, achieving the effect of rapid positioning. The lid bodies 14 slide down along the second positioning posts 25, contact the rubber pads 28 during the sliding process, and squeeze the four buffer plates 26 to slide outwards by their own weight. When the lid bodies 14 pass through the buffer plates 26 or the weight of the lid bodies 14 is not sufficient to push the buffer plates 26 to slide, the second springs 27 drive the four buffer plates 26 to slide back to the center. After the lid bodies 14 pass through the buffer plates 26, they slide down along the first positioning posts 13 to the bottom and are stacked on the remaining lid bodies 14. By setting the sliding buffer plates 26 on the first positioning posts 13 to buffer the rapidly falling lid bodies 14, it is possible to avoid the collision and damage between two lid bodies 14 during the sliding process, which is beneficial to improving the assembly quality.
[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
