Description

Technical Field

[0001] This application relates to the field of lunchbox manufacturing, and in particular to a capping device. Background Technology

[0002] A lunchbox is a common serving container in the catering industry, consisting of a box body and a lid. The assembly of the box body and lid is a crucial step in the lunchbox manufacturing process.

[0003] Currently, the assembly of the container and the lid mainly relies on manual labor. The specific process is as follows: when the container is transported to the work station along the assembly line, the operator first removes the container from the assembly line, then assembles the lid onto the container, and finally puts the assembled container back onto the assembly line.

[0004] However, this traditional production model has significant drawbacks: in order to meet the production efficiency requirements of the products, manufacturers need to employ a large number of operators to perform repetitive assembly work at the same time, which greatly increases labor costs and reduces the economic benefits and market competitiveness of lunch box manufacturers. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a capping device that can automatically assemble the box body and the top cover.

[0006] The capping device provided in this application adopts the following technical solution:

[0007] A capping device includes a base, a turntable rotatable about its own axis and mounted on the base, a first drive module for driving the turntable to rotate, and a plurality of bearing positions spaced apart on the circumferential surface of the turntable. The turntable is horizontally arranged and its circumference is provided with a first feeding mechanism, a second feeding mechanism, a pressing mechanism and a unloading mechanism in sequence.

[0008] By adopting the above technical solution, the turntable can drive the box body through the second feeding mechanism and the pressing mechanism in sequence during its rotation. The second feeding mechanism and the pressing mechanism can cooperate with each other to assemble the top cover onto the box body without manual operation. This not only effectively improves the assembly efficiency of the lunch box, but also reduces labor costs.

[0009] In one specific implementation, a support plate is provided on at least one side of the turntable, the support plate is rotatably connected to the bottom of the turntable, the second feeding mechanism and the pressing mechanism are respectively provided on the side of the support plate, and a plurality of slots are spaced apart on the peripheral surface of the turntable, the plurality of slots can pass over the support plate during the rotation of the turntable, and the slots and the support plate form the bearing position.

[0010] By adopting the above technical solution, the support plate can cooperate with the slot and support the box, preventing the box from falling outward during the rotation of the turntable.

[0011] In one specific implementation scheme, the first feeding mechanism includes a first conveyor belt assembly, and the unloading mechanism includes a second conveyor belt assembly. The first conveyor belt assembly and the second conveyor belt assembly are located on opposite sides of the turntable, and the conveying direction of the first conveyor belt assembly is the same as that of the second conveyor belt assembly.

[0012] In one specific implementation scheme, a material blocking component is provided at the end of the conveying direction of the first conveyor belt assembly. The material blocking component includes a first support, a movable material blocking plate disposed on the first support, and a second drive module for driving the material blocking plate to move. The material blocking plate is located above the first conveyor belt assembly and its moving direction is perpendicular to the conveying direction of the first conveyor belt assembly.

[0013] By adopting the above technical solution, the material blocking plate can block the box during its movement, so that several boxes output by the first feeding component can enter the turntable in sequence and complete the capping operation, which effectively improves the assembly quality and efficiency of the lunch box.

[0014] In one specific implementation, the second feeding mechanism includes a second support, on which a material storage component and a material picking component are provided. The material storage component is located above the material picking component, and the plurality of bearing positions can pass directly below the material picking component in sequence during the rotation of the turntable.

[0015] By adopting the above technical solution, the material picking component and the material storage component can cooperate with each other and quickly transfer the top cover to the box located at the bearing position, effectively improving the material feeding efficiency of the top cover.

[0016] In one specific implementation, the storage assembly includes a base plate disposed on the upper end of the second support, a plurality of baffles disposed on the base plate, the plurality of baffles and the base plate forming a hopper, and the base plate also having a discharge port communicating with the hopper.

[0017] By adopting the above technical solution, several top covers can be placed in the hopper and output outwards sequentially through the discharge port, effectively improving the feeding efficiency of the top covers.

[0018] In one specific implementation, the second feeding mechanism further includes a baffle assembly, which includes two baffle plates movable along a direction that moves closer to or further away from each other and mounted on the second support, and a third drive module for driving the two baffle plates to move. The two baffle plates are respectively located on both sides below the discharge port, and the two baffle plates can block the discharge port during their respective movement strokes.

[0019] By adopting the above technical solution, the two baffles can block the discharge port to limit the upper cover in the discharge port before the material taking component takes the material, so as to prevent the upper cover from falling off accidentally and affecting the subsequent assembly process.

[0020] In one specific implementation, the second feeding mechanism further includes a clamping assembly, which includes two clamping blocks movable along a direction that moves closer to or further away from each other, mounted on the second support, and a fourth driving module for driving the two clamping blocks to move. The two clamping blocks are respectively able to abut against both sides of the hopper during their respective movement strokes.

[0021] By adopting the above technical solution, the two clamping blocks can clamp the top cover in the hopper from both sides, so as to limit the remaining top covers in the hopper when the top cover in the discharge port is output outward, and prevent too many top covers from falling outward and affecting the subsequent assembly process.

[0022] In one specific implementation, the material handling assembly includes a lifting and rotatable material handling plate mounted on the second bracket, a fifth drive module for driving the material handling plate, and a plurality of suction nozzles located on one side of the material handling plate, wherein the rotation axis of the material handling plate extends in a horizontal direction.

[0023] By adopting the above technical solution, the material picking plate can quickly pick up the top cover and place it on the box during its lifting and rotating strokes, effectively improving the material feeding efficiency of the top cover.

[0024] In one specific implementation scheme, the pressing mechanism includes a third support, a liftable pressure plate mounted on the third support, and a sixth drive module for driving the pressure plate to move up and down. The plurality of bearing positions can pass directly under the pressure plate in sequence during the rotation stroke of the turntable.

[0025] By adopting the above technical solution, the pressure plate can press the top cover and the box body together during its lifting stroke, which effectively improves the assembly quality of the lunch box.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The turntable can drive the box through the second feeding mechanism and the pressing mechanism in sequence during its rotation. The second feeding mechanism and the pressing mechanism can cooperate with each other to assemble the top cover onto the box without manual operation. This not only effectively improves the assembly efficiency of the lunch box, but also reduces labor costs. Attached Figure Description

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] See Figure 1-3 As shown, a capping device includes a base 1, a turntable 2 rotatable about its own axis and mounted on the base 1, a first drive module 3 for driving the turntable 2 to rotate, and multiple bearing positions spaced apart on the circumferential surface of the turntable 2. The turntable 2 is horizontally arranged and its rotation axis extends vertically. A first feeding mechanism 4, a second feeding mechanism 5, a pressing mechanism 6, and a discharging mechanism 7 are sequentially arranged around the circumference of the turntable 2.

[0039] The first drive module 3 is a motor, and the first feeding mechanism 4 is used to transport the box body 100 to the bearing position on the turntable 2. During its rotation, the turntable 2 can drive the box body 100 to pass sequentially through the second feeding mechanism 5 and the pressing mechanism 6. The second feeding mechanism 5 is used to transfer the upper cover 101 onto the box body 100, and the pressing mechanism 6 is used to press the upper cover 101 and the box body 100 together. Then, the unloading mechanism 7 outputs the pressed lunch box from the bearing position. In this way, the turntable 2, the first feeding mechanism 4, the second feeding mechanism 5, the pressing mechanism 6, and the unloading mechanism 7 can cooperate with each other to quickly assemble the upper cover 101 onto the box body 100 without manual operation, which can not only effectively improve the assembly efficiency of the lunch box, but also reduce labor costs.

[0040] In this embodiment, a semi-circular horizontal support plate 8 is provided on one side of the turntable 2. The support plate 8 is located on one side of the machine base 1 in the width direction and is rotatably connected to the bottom of the turntable 2. Several support rods are provided below the support plate 8 and are connected to the machine base 1. The second feeding mechanism 5 and the pressing mechanism 6 are respectively provided on the side of the support plate 8 away from the turntable 2. Multiple slots 21 are spaced apart on the peripheral surface of the turntable 2. During the rotation of the turntable 2, the multiple slots 21 can pass over the support plate 8. When the slots 21 pass over the support plate 8, a bearing position can be formed between them to accommodate the box 100. In this way, the support plate 8 can cooperate with the slots 21 and support the box 100, preventing the box 100 from falling downwards during the rotation of the turntable 2.

[0041] A retaining ring 9 is provided on the outer side of the support plate 8, and the slot of the slot 21 faces the retaining ring 9. When the box 100 is accommodated in the slot 21, the retaining ring 9 can limit and guide the box 100 to prevent the box 100 from shaking or displacing during the rotation of the turntable, thereby improving the pressing accuracy of the subsequent upper cover 101.

[0042] In this embodiment, the first feeding mechanism 4 includes a first conveyor belt assembly 41, the end of the first conveyor belt assembly 41 extending into the turntable 2 below in the conveying direction, and the unloading mechanism 7 includes a second conveyor belt assembly, the beginning of the second conveyor belt assembly extending into the turntable 2 below in the conveying direction, so as to facilitate the flow of the box 100 between the first conveyor belt assembly 41, the turntable and the second conveyor belt assembly.

[0043] The first conveyor belt assembly 41 and the second conveyor belt assembly are both belt conveyors in the prior art. They are located on opposite sides of the turntable 2. The first conveyor belt assembly 41 and the second conveyor belt assembly operate synchronously and their conveying directions extend along the length of the base. The support plate 8 is located on one side of the conveying direction of the first conveyor belt assembly 41 and the second conveyor belt assembly.

[0044] Furthermore, a material-blocking component 42 is provided at the end of the first conveyor belt assembly 41 in the conveying direction. The material-blocking component 42 includes a first support 421, a movable material-blocking plate 422 mounted on the first support 421, and a second drive module 423 for driving the material-blocking plate 422. The second drive module 423 is a cylinder. The material-blocking plate 422 is vertically mounted above the first conveyor belt assembly 41, and its direction of movement is perpendicular to the conveying direction of the first conveyor belt assembly 41. When the first conveyor belt assembly 41 conveys the box 100, the material-blocking plate 422 can extend and block the box 100, separating the previous box 100 from the subsequent box 100. This allows several boxes 100 output from the first feeding mechanism 4 to sequentially enter the turntable 2 and complete the capping operation, effectively improving the assembly quality and efficiency of the lunch boxes.

[0045] In this embodiment, combined with Figure 2 As shown, the second feeding mechanism 5 includes a second support 51, on which a material storage component 52 and a material picking component 53 are provided. The material picking component 53 is located in the middle of the second support 51, and the material storage component 52 is located in the upper part of the second support 51 and above the material picking component 53. Multiple bearing positions can pass directly below the material picking component 53 in sequence during the rotation of the turntable 2.

[0046] Furthermore, the storage assembly 52 includes a base plate 521 disposed on the upper end of the second support 51, and multiple baffles 522 disposed on the base plate 521. The multiple baffles 522 are arranged around and form a hopper with the base plate 521. The hopper is used to accommodate the top cover 101. The base plate 521 is also provided with a discharge port 523 communicating with the hopper. The discharge port 523 is used to output the top cover 101 outward.

[0047] In this embodiment, the second feeding mechanism 5 further includes a baffle assembly 54, which includes two baffle plates 541 movable along directions that are close to or far from each other, mounted on the second bracket 51, and a third drive module 542 for driving the two baffle plates 541 to move. The third drive module 542 includes two cylinders for driving the two baffle plates 541 respectively. The two baffle plates 541 are located below the two sides of the discharge port 523, and their arrangement direction is the same as the length direction of the machine base 1.

[0048] The two baffles 541 can block the two sides of the discharge port 523 during their respective travel to limit the upper cover 101 in the discharge port 523 before the material picking component 53 picks up the material, so as to prevent the upper cover 101 from falling off accidentally and affecting the subsequent assembly process; while the material picking component 53 picks up the material, the two baffles 541 are relatively far apart so that the upper cover 101 can be easily output from the discharge port 523.

[0049] In this embodiment, the second feeding mechanism 5 further includes a clamping assembly 55, which includes two clamping blocks 551 movable along directions that are close to or far from each other, mounted on the second support 51, and a fourth drive module 552 for driving the two clamping blocks 551 to move. The fourth drive module 552 includes two cylinders for driving the two clamping blocks 551 to move respectively. The arrangement direction of the two clamping blocks 551 is the same as the length direction of the machine base 1, and both can abut against the sides of the hopper during their respective travel.

[0050] Two clamping blocks 551 are located on the upper side of the substrate 521. They can extend into the hopper from both sides through the gap between multiple baffles 522 to clamp the next cover 101 entering the discharge port 523, thereby limiting the remaining covers 101 in the hopper. In this way, when the two baffles 541 are relatively far apart, only one cover 101 in the discharge port 523 is output outward, while the remaining covers 101 remain stationary under the limiting effect of the two clamping blocks 551, preventing too many covers 101 from falling outward and affecting the subsequent assembly process.

[0051] The two clamping blocks 551 correspond one-to-one with the two baffle plates 541, and the distance between the corresponding clamping blocks 551 and baffle plates 541 is the same as the thickness of the upper cover 101. When the two clamping blocks 551 are relatively close, they can clamp the upper cover 101 behind the upper cover 101 in the discharge port 523, and the upper cover 101 behind the upper cover 101 can block the other upper covers 101 above it, thereby limiting the upper cover 101 in the hopper.

[0052] In this embodiment, the material-picking assembly 53 includes a lifting plate 531 mounted on a second bracket 51, which is liftable and rotatable about its own axis; a fifth drive module 532 for driving the movement of the material-picking plate 531; and several suction nozzles 533 located on one side of the material-picking plate 531. The rotation axis of the material-picking plate 531 extends along the width direction of the machine base. The fifth drive module 532 includes a cylinder and a motor mounted on the piston rod of the cylinder. The material-picking plate 531 is mounted on the output shaft of the motor. The suction nozzles 533 are connected to an air source and can perform negative pressure adsorption on the upper cover 101. During its lifting and rotating strokes, the material-picking plate 531 can quickly pick up the upper cover 101 and place it on the box body 100, effectively improving the feeding efficiency of the upper cover 101.

[0053] In this embodiment, combined with Figure 3As shown, the pressing mechanism 6 includes a third support 61, a liftable pressure plate 62 mounted on the third support 61, and a sixth drive module 63 for driving the pressure plate 62 to rise and fall. The pressure plate 62 is horizontally positioned, and the sixth drive module 63 is a cylinder. Multiple bearing positions can sequentially pass directly under the pressure plate 62 during the rotation stroke of the turntable 2. The pressure plate 62 can press the upper cover 101 and the box body 100 together during its lifting stroke, effectively improving the assembly quality of the lunch box.

[0054] The pressing mechanism 6 also includes a fourth support 64 located directly below the pressing plate 62. A horizontal support plate 65 is provided on the fourth support 64. The support plate 65 supports the underside of the support plate 8 to hold the support plate 8 in place and prevent the support plate 8 from bending when the pressing plate 62 is pressed down, thereby improving the pressing quality of the lunch box.

[0055] The implementation principle of a capping device according to an embodiment of this application is as follows:

[0056] The first conveyor belt assembly 41 transports the boxes 100 sequentially toward the turntable. After the previous box 100 enters the slot 21, the baffle plate 422 extends and blocks the subsequent box 100.

[0057] As the turntable rotates, the box 100 that enters the slot 21 reaches the second feeding mechanism 5. The picking plate 531 rises and adheres to the upper cover 101. Then, the two baffle plates 541 move away from the discharge port 523 and release the restriction on the upper cover 101. The picking plate 531 descends and removes the upper cover 101 from the discharge port 523.

[0058] Then the material handling plate 531 rotates 180° and descends again, placing the top cover 101 on the box body 100;

[0059] While the top cover 101 is placed on the material receiving plate 531, the two baffle plates 541 move closer to each other and block the discharge port 523 again. The two clamping blocks 551 move further apart and release the restriction on the top cover 101 in the hopper. Then the top cover 101 in the hopper falls downward and is supported by the two baffle plates 541. Then the two clamping blocks 551 move closer to each other and clamp the top cover 101 in the hopper again.

[0060] As the turntable 2 rotates, the box 100 with the top cover 101 is placed at the pressing mechanism 6, and the pressing plate 62 descends and presses the top cover 101 against the box 100.

[0061] The pressed lunch box reaches the feeding mechanism 7 as the turntable rotates, and then the feeding mechanism 7 outputs the lunch box outward;

[0062] Repeat the above steps to achieve automated assembly of the lunch boxes.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
