[0022] Reference Figures 1-6 A bottle cap bundling and palletizing machine includes a frame 100 and a bottle cap feeding device 200, a reversing device 300, an arranging device 400, a pad feeding device 500, and a material transfer device 600 disposed on the frame 100. The rack 100 is equipped with a stacking station 110, which serves as the core working area for stacking pads and bottle cap stack arrays. The bottle cap feeding device 200 receives the packaged and horizontally stacked bottle caps 700 provided by the previous process, realizing the stable reception and transfer of front-end materials. The reversing device 300 is connected to the discharge end of the bottle cap feeding device 200 and is used to switch the horizontal stack of bottle caps 700 to a vertical position. Its core function is to switch the horizontally conveyed stack of bottle caps 700 to a vertical position, so as to provide a compliant placement posture for subsequent array arrangement and bundled packaging. The arranging device 400 is set on the first side of the stacking station 110 and is connected to the discharge end of the reversing device 300. It is used to neatly stack multiple vertical bottle cap stacks 700 in the horizontal direction into a bottle cap stack array with a preset spacing and number. The pad feeding device 500 is located on the second side of the stacking station 110 to provide pads for bottom support and protection of the bottle cap stack array; The material transfer device 600 is connected between the arranging device 400 and the pad feeding device 500, and undertakes dual transfer functions. It accurately places the pads output by the pad feeding device 500 onto the stacking station 110, and transfers the bottle cap stack array formed by the arranging device 400 to the pads to complete the combined stacking action.

[0023] I. Reference Figures 1-2 The operation process and principle of the bottle cap feeding device 200: The bottle cap feeding device 200 includes a first feeding track 210, a first clamping component 220, a first XZ axis motion module 230, and a first pushing component 240. The end of the first feeding track 210 is connected to the reversing device 300. The first clamping component 220 is located at the output end of the first XZ axis motion module 230 and is used to clamp the packaged and horizontally arranged bottle cap stack 700. The first XZ axis motion module 230 is used to transfer the bottle cap stack 700 onto the first feeding track 210. The first pushing component 240 is located at the beginning of the first feeding track 210 and is used to push the bottle cap stack 700 on the first feeding track 210 one by one to the reversing device 300.

[0024] Its core principle is to achieve the orderly transfer of horizontal stacks of bottle caps through a combination of mechanical clamping and rail conveying. The specific operation process is as follows: 1. When the horizontal stack of bottle caps 700 is conveyed, the first clamping component 220 at the output end of the first XZ axis motion module 230 moves to both sides of the stack of bottle caps 700. 2. The first clamping assembly 220 includes a first cylinder 221 and a second cylinder 222 arranged on both sides, which are used to push the left and right sides of the bottle cap stack 700 respectively. At this time, the first cylinder 221 and the second cylinder 222 extend synchronously and clamp and fix the bottle cap stack 700 from the left and right sides to ensure that the material does not shift or scatter during the transfer process. 3. The first XZ axis motion module 230 drives the clamped bottle cap stack 700 to move along the X axis (horizontal direction) and Z axis (vertical direction), accurately transferring it to the beginning position of the first feeding track 210. Then the first cylinder 221 and the second cylinder 222 retract and release, and the bottle cap stack 700 is stably placed on the first feeding track 210. 4. The first feeding component 240 is activated, pushing the bottle cap stack 700 one by one along the length of the first feeding track 210 to the end of the track, and finally sending it into the reversing device 300, thus completing the material transfer in the feeding process.

[0025] II. Reference Figures 1-3 , Figures 5-6 The operation process and principle of the commutator 300 The reversing device 300 includes a reversing mold 310, on which a reversing channel 311 is provided. The reversing channel 311 has an inlet 312 that is horizontally arranged near the bottle cap feeding device 200 and an outlet 313 that is vertically arranged near the arranging device 400. The bottle cap stack 700 can enter the reversing channel 311 through the inlet 312 and gradually switch to a vertical arrangement and be conveyed out through the outlet 313.

[0026] The core design utilizes the gradient structure of the reversing channel 311 to achieve damage-free reversal of the bottle cap stack from horizontal to vertical. The principle is to guide the material's posture to change naturally using the channel shape, avoiding packaging damage caused by hard contact. The specific operation process is as follows: 1. The horizontal stack of bottle caps 700 pushed from the first feeding track 210 enters the channel through the inlet 312 arranged horizontally along the reversing channel 311. 2. The reversing channel 311 has a gradually curved structure from the inlet 312 to the outlet 313. As the bottle cap stack 700 moves continuously in the channel, its placement gradually transitions from horizontal to vertical. The smooth inner wall of the channel reduces the resistance to material movement. 3. When the bottle cap stack 700 moves to the discharge port 313 near the arrangement device 400, it has been completely switched to vertical arrangement. Then it is discharged from the vertical discharge port 313 and enters the second feeding track 410 of the arrangement device 400 to complete the direction conversion operation.

[0027] III. Reference Figures 1-3 The operation process and principle of the arranging device 400 The arranging device 400 includes a second feeding track 410, a stacking frame 420, and a second pushing component 430. The beginning end of the second feeding track 410 is connected to the output end of the reversing device 300. The stacking frame is connected to the end of the second feeding track 410. The vertical stack of bottle caps 700 can enter one side of the stacking frame one by one through the second feeding track 410. The second pushing component 430 is disposed on one side of the stacking frame and is used to push the stack of bottle caps 700 arranged on one side of the stacking frame to the other side of the stacking frame. Preferably, the second pushing component 430 is a cylinder.

[0028] The core principle is to achieve a neat array arrangement of vertically stacked bottle caps through a combination of rail conveying and cylinder pushing, ensuring that the number and spacing of each array are uniform. The specific operation process is as follows: 1. The vertical bottle cap stack 700 discharged from the discharge port 313 of the reversing device 300 is conveyed one by one to the end of the second feeding track 410 and enters one side area of ​​the push frame 420. The inner dimensions of the push frame 420 match the preset bottle cap stack array specifications, limiting the material arrangement range. 2. When the number of vertical bottle cap stacks 700 in one side area of ​​the pusher frame 420 reaches a preset value (such as 3 × 3 or 4 × 4), the cylinder piston rod of the second pusher component 430 extends and pushes the neatly arranged bottle cap stacks as a whole to the other side area of ​​the pusher frame 420 along the width direction of the pusher frame 420, forming a standardized bottle cap stack array. 3. After the push is completed, the cylinder piston rod of the second pusher component 430 retracts and resets, waiting for the next batch of vertical bottle cap stacks 700 to be arranged in one area of ​​the pusher frame 420, and enter the next pusher cycle. At the same time, the formed bottle cap stack array stays on the other side of the pusher frame 420, waiting for the transfer device 600 to transfer it.

[0029] IV. Reference Figures 1-4 Operation process and principle of material transfer device 600 and pad feeding device 500 The material transfer device 600 includes a second XZ axis motion module 610, a third XZ axis motion module 620, a first vacuum suction cup 630, and a second vacuum suction cup 640; the second XZ axis motion module 610 is connected between the stacking station 110 and the arrangement device 400; the first vacuum suction cup 630 is located at the output end of the second XZ axis motion module 610; the third XZ axis motion module 620 is connected between the stacking station 110 and the pad feeding device 500; and the second vacuum suction cup 640 is located at the output end of the third XZ axis motion module 620.

[0030] The 500 pad feeding device is used to continuously output pads. The two work together to achieve synchronous operation of pad laying and bottle cap stack array transfer. The principle is to use the suction force of the vacuum suction cup to achieve stable material gripping, and the movement trajectory is precisely controlled by the XZ axis module. The specific action process is as follows: 1. The pad feeding device 500 automatically outputs a single pad. The third XZ axis motion module 620 drives the second vacuum suction cup 640 to move above the pad. The vacuum suction cup is activated to generate suction force and firmly adsorb the pad. 2. The third XZ axis motion module 620 drives the second vacuum suction cup 640 of the adsorption pad to the preset position of the stacking station 110. Then the vacuum suction cup stops working, and the pad is placed stably on the stacking station 110, completing the pad laying. 3. At the same time, the second XZ axis motion module 610 drives the first vacuum suction cup 630 to move to the top of the bottle cap stack array on the other side of the push frame 420. The first vacuum suction cup 630 is activated to generate suction force, which synchronously adsorbs and fixes the entire bottle cap stack array. 4. The second XZ axis motion module 620 drives the first vacuum suction cup 630 to move to the pad that has been laid in the stacking station 110. After adjusting the position to align the array with the pad, the vacuum suction cup stops working and the bottle cap stack array is placed stably on the pad, completing the combination stacking action. 5. The second XZ axis motion module 610 and the third XZ axis motion module 620 respectively drive the first vacuum chuck 630 and the second vacuum chuck 640 to reset, waiting for the next material transfer operation, and repeating the cycle to achieve continuous stacking.

[0031] V. Reference Figure 1 The subsequent processes and principles of the packaging line The packaging line constructed based on the palletizer described above also includes a wrapping device 810, a heat shrinking device 820, a labeling device 910, and a stacking device 920. The wrapping device 810 is located on the third side of the stacking station 110 and is used to wrap the pads and bottle cap stacks with heat shrink film. The heat shrinking device 820 is connected to the discharge end of the wrapping device 810 and is used to heat shrink the heat shrink film wrapped on the pads and bottle cap stacks. In some embodiments, a bottle cap bundling palletizer also includes a labeling device 910 connected to the discharge end of the heat shrinking device 820 and is used to affix labels to the packaged pads and bottle cap stacks. In a further embodiment, a bottle cap bundling palletizer also includes a stacking device 920 connected to the discharge end of the labeling device 910 and is used to stack the labeled pads and bottle cap stacks.

[0032] The core is to form a complete closed-loop back-end packaging system of "palletizing - wrapping - heat shrinking - labeling - stacking". The principle is to achieve automated protection and organized storage of finished products through the orderly connection of various devices. The specific operation process is as follows: 1. The material that has been assembled with the pad and bottle cap stack array on the stacking station 110 is conveyed to the wrapping device 810 set on the third side. The wrapping device 810 wraps the heat shrink film around the surface of the material to form a preliminary protective layer. 2. The material wrapped in heat-shrink film enters the heat-shrinking device 820. The heat-shrinking device 820 heats the material to cause the heat-shrink film to shrink tightly and adhere to the surface of the material, enhancing the tightness and protective properties of the packaging, thus completing the heat-shrink packaging. 3. After heat shrink packaging, the material is conveyed to the labeling device 910, which automatically affixes the product label to the preset position (such as the side or front of the material) to achieve product information identification. 4. Finally, the labeled materials enter the stacking device 920, which stacks the individual material units layer by layer to a preset height to form bundled finished product stacks, which facilitates subsequent warehousing and transportation, and completes the entire operation process of the packaging line.

[0033] The advantages of this utility model are: the above structure enables fully automated operation from receiving, reversing, and arranging the horizontal bottle cap stacks to combining and stacking with the pads, effectively filling the technical gap in the back-end bundling and palletizing process of existing production lines, greatly improving the continuity and automation level of the overall packaging process, matching the high-speed production rhythm of the front-end production line, reducing labor costs and labor intensity, and meeting the high-efficiency and standardized requirements of large-scale bottle cap production.
