Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a connecting ring packaging device and its process. Background Technology

[0002] Connecting rings, also called coupling rings, are connecting components used in refrigerator refrigeration systems for connecting pipes. Refrigeration systems require metal pipes, and connecting rings, combined with cold extrusion connection technology, allow for seamless connection of these metal pipes.

[0003] After production and processing, the connecting rings need to be packaged in plastic bags. Due to the materials and processing techniques used, the connecting rings are relatively valuable. Therefore, it is necessary to ensure that the number of connecting rings in each plastic bag is consistent during packaging to facilitate subsequent sales to the market. Thus, the quantity of connecting rings in each bag must be recorded during packaging.

[0004] Existing connecting ring packaging is typically done manually, and each bag usually needs to contain 1,000 connecting rings. The manual packaging process usually includes: printing self-adhesive labels, labeling the packaging bags, counting the connecting rings (using a counting board, 250 rings / time, repeated 4 times), packing 1,000 products into the packaging bags, and sealing the packaging bags. These steps usually require multiple people to operate, resulting in low packaging efficiency and high labor costs.

[0005] Therefore, there is a need for a mechanical device that can automatically count and package products, along with a customized packaging process, to improve the efficiency of product packaging and reduce labor costs. Summary of the Invention

[0011] Optionally, a discharge hopper is provided at one end of the support frame away from the feed hopper. The discharge hopper is located below the plurality of counting structures. The discharge hopper is fixedly connected to the support frame. The lower end of the discharge hopper is connected to the packaging device. A second sensor is provided inside the discharge hopper. The second sensor is used to record the number of times the connecting ring falls.

[0012] Optionally, the conveying structure includes a V-shaped guide plate with a V-shaped cross-section. The V-shaped guide plate is disposed between the rotating drum and the counting structure. One end of the V-shaped guide plate corresponding to the rotating drum is higher than the other end corresponding to the counting structure. The V-shaped guide plate is fixedly mounted on the support frame by a mounting rod. The end of the V-shaped guide plate near the rotating drum is located below the rotating drum.

[0027] Existing connecting ring packaging is typically done manually, with each bag usually requiring 1,000 connecting rings. The manual packaging process generally includes: printing self-adhesive labels, labeling the packaging bags, counting the connecting rings (using a counting plate, 250 rings / time, repeated 4 times), packing 1,000 products into the packaging bag, and sealing the bag. These steps usually require multiple operators, resulting in low packaging efficiency and high labor costs. Therefore, there is a need for automated counting and packaging machinery, along with a customized packaging process, to improve product packaging efficiency and reduce labor costs.

[0028] In view of this, this application proposes a connecting ring packaging device and its process method.

[0029] In the embodiments of this application, reference is made to Figures 1 to 5 The aforementioned connecting ring packaging equipment includes: a storage hopper 1, an elevator 2, a counting device 3, a packaging device 4, and a controller 5. The storage hopper 1 is used to temporarily store products that need to be counted and packaged. The elevator 2 is used to transport the products in the storage hopper 1 to a high place and let the products fall into the counting device 3. The counting device 3 is used to calculate the quantity of products. The packaging device 4 is used to package the calculated quantity of products and print labels on the packaging bags. The controller 5 is used to control the operation of the elevator 2, the counting device 3, and the packaging device 4, and to set relevant parameters.

[0030] The product in this application is a connecting ring 6, which is a cylindrical structure made of metal.

[0031] The packaging device 4 (the specific structure of the packaging device is existing technology and will not be described in detail here) includes a packaging film feeding structure, a label printing structure, a packaging film punching structure, a packaging film cutting structure, and a packaging bag sealing structure. The packaging film feeding structure has a cylindrical roll of packaging film made of nylon composite material. When unfolded, the packaging film is a cylindrical structure with open ends. The packaging film feeding structure feeds the packaging film, allowing it to pass sequentially through the label printing structure, the packaging film punching structure, the packaging film cutting structure, and the packaging bag sealing structure. The label printing structure prints labels with relevant product parameters on the surface of the packaging film, ensuring each packaging bag has one label. The packaging film punching structure creates vent holes in the packaging film, allowing air to escape from the packaging bag. The packaging film cutting structure cuts the packaging film and controls the size of the packaging bag by controlling the length of the packaging film. The packaging bag sealing structure seals both ends of the packaging film, forming a complete packaging bag after cutting.

[0032] refer to Figure 2 The counting device 3 includes multiple flipping structures, multiple conveying structures, multiple first sensors, and multiple counting structures 340. Each of the flipping structures, conveying structures, first sensors, and counting structures 340 forms a counting group, and each counting group can count a certain number of products.

[0033] refer to Figure 2 The counting device 3 also includes a support frame 310, which includes two horizontal bars 311 and multiple vertical bars 312. The two horizontal bars 311 are arranged parallel to each other, and multiple vertical bars 312 are fixedly installed at the lower ends of the two horizontal bars 311. The lower ends of the vertical bars 312 are connected to the packaging device 4. A rectangular outer shell 380 is provided on the outside of the support frame 310. The outer shell 380 is used to protect the internal components. The top surface of the outer shell 380 is open to facilitate workers to observe and intervene in the counting of the counting device 3. The support frame 310 is used to support and fix the counting device 3 above the packaging device 4.

[0034] refer to Figure 2 , Figure 3A feeding hopper 320 is installed above one end of the two crossbars 311. The elevator 2 will transfer the product into the feeding hopper 320. The feeding hopper 320 is fixedly connected to the two crossbars 311. The tilting structure includes rotating cylinders 330. Multiple parallel rotating cylinders 330 are arranged between the two crossbars 311 near the feeding hopper 320. The multiple rotating cylinders 330 are all inclined, that is, the end of the rotating cylinder 330 near the feeding hopper 320 is higher than the end of the rotating cylinder 330 away from the feeding hopper 320. In this embodiment, there are ten rotating cylinders 330. The rotating cylinders 330 are all cylindrical structures. The two horizontal bars 311 are evenly distributed at the front and back, and mounting plates 331 are respectively set at the two ends of the multiple rotating cylinders 330. The two ends of the two mounting plates 331 are respectively fixedly installed on the two horizontal bars 311. Through holes 332 are opened on the two mounting plates 331 corresponding to the multiple rotating cylinders 330. Bearings 333 are installed in the through holes 332. The two ends of the multiple rotating cylinders 330 are respectively inserted into the corresponding through holes 332, and the two ends of the multiple rotating cylinders 330 are rotatably connected to the corresponding mounting plates 331 through the bearings 333, so that the multiple rotating cylinders 330 can rotate around their own axis.

[0035] refer to Figure 2 , Figure 3 A first rotating shaft 334 is provided between two crossbars 311 near multiple rotating drums 330. The two ends of the first rotating shaft 334 are rotatably connected to the corresponding crossbars 311. A first drive motor (not shown in the figure) is provided at one end of the first rotating shaft 334. The first drive motor is connected to the first rotating shaft 334 through a transmission component, so that the first drive motor can drive the first rotating shaft 334 to rotate. Annular worm gears 335 are fitted on the outer side of multiple rotating drums 330 near the first rotating shaft 334. Worms 336 are fitted on the first rotating shaft 334 corresponding to the multiple worm gears 335. The multiple worm gears 335 cooperate with the corresponding worms 336, so that the first rotating shaft 334 can drive the multiple rotating drums 330 to rotate simultaneously through the multiple worm gears 335 and worms 336. When the connecting ring 6 enters the rotating drum 330, the rotating drum 330 will drive the internal connecting ring 6 to rotate, so that the axis of the connecting ring 6 passing through the rotating drum 330 is parallel to the axis of the rotating drum 330.

[0036] refer to Figure 2 An inclined feed cylinder 321 is provided between the feed hopper 320 and the multiple rotating cylinders 330. One end of the multiple feed cylinders 321 is fixedly connected to the feed hopper 320, and the other end of the multiple feed cylinders 321 extends into the corresponding rotating cylinder 330. The end of the feed cylinder 321 connected to the feed hopper 320 is higher than the end of the feed cylinder 321 extending into the rotating cylinder 330, so that the product in the feed hopper 320 can enter the corresponding rotating cylinder 330 through the feed cylinder 321 under the action of gravity.

[0037] refer to Figure 2Multiple counting structures 340 are provided at the end of the two crossbars 311 away from the feed hopper 320. The number of counting structures 340 is the same as the number of rotating drums 330, and the multiple counting structures 340 correspond one-to-one with the multiple rotating drums 330. Each counting structure 340 includes a counting wheel 341 and multiple counting rods 342. The multiple counting rods 342 are evenly distributed around the counting wheel 341, and one end of each counting rod 342 is fixedly connected to the counting wheel 341. The counting rods 342 at the same angle on the multiple counting wheels 341 correspond one-to-one and are parallel to each other. The multiple counting wheels 341 are fixedly mounted on the same second rotating shaft. The two ends of the second rotating shaft are rotatably connected to the two crossbars 311 respectively. One end of the second rotating shaft is connected to a second drive motor (not shown in the figure). As shown in the figure, the second drive motor will drive the counting wheel 341 and the counting rods 342 to rotate clockwise through the second rotating shaft. The second drive motor is a stepper motor or a servo motor. The second drive motor can drive the counting wheel 341 to rotate a certain angle and pause under program control.

[0038] refer to Figure 2 The conveying structure includes V-shaped guide plates 350. Inclined V-shaped guide plates 350 are set between two crossbars 311 and between multiple rotating drums 330 and corresponding counting structures 340. The cross-section of the V-shaped guide plate 350 is V-shaped. One end of the V-shaped guide plate 350 corresponding to the rotating drum 330 is higher than the other end of the V-shaped guide plate 350 corresponding to the counting structure 340, so that the product can move along the V-shaped guide plate 350 towards the counting structure 340 under the action of gravity. Two mounting rods 353 are set below the multiple V-shaped guide plates 350. The two ends of the two mounting rods 353 are respectively fixedly connected to the two crossbars 311. The multiple V-shaped guide plates 350 are all fixedly connected to the two mounting rods 353. The mounting rods 353 are used to install and fix the multiple V-shaped guide plates 350.

[0039] refer to Figure 3 The V-shaped guide plate 350 is located below the rotating drum 330 at one end, allowing the product inside the rotating drum 330 to fall onto the corresponding V-shaped guide plate 350. The inner side of the rotating drum 330 is provided with a tapered surface 337 at the end near the V-shaped guide plate 350. The diameter of the tapered surface 337 at the end near the V-shaped guide plate 350 is larger than the diameter at the end away from the V-shaped guide plate 350, which can reduce the height of the step between the rotating drum 330 and the V-shaped guide plate 350 and reduce the possibility of the connecting ring 6 flipping when it falls onto the V-shaped guide plate 350.

[0040] refer to Figure 3A toothed ring 338 is fixedly fitted on the outer side of the rotating drum 330 near the V-shaped guide plate 350. The toothed ring 338 contacts the V-shaped guide plate 350. When the rotating drum 330 rotates, the teeth on the toothed ring 338 will continuously strike the V-shaped guide plate 350, causing the rotating drum 330 and the V-shaped guide plate 350 to vibrate slightly, so that the connecting ring 6 can move smoothly along the rotating drum 330 and the V-shaped guide plate 350.

[0041] refer to Figure 4 and Figure 5 A through groove 351 is opened in the middle of the V-shaped guide plate 350 corresponding to the counting rod 342. The width of the through groove 351 is greater than the diameter of the counting rod 342. The through groove 351 is used for the counting rod 342 to pass through. The width of the through groove 351 is less than the diameter of the connecting ring 6 to prevent the connecting ring 6 from falling out of the through groove 351.

[0042] refer to Figure 2 and Figure 4 On the sides of multiple V-shaped guide plates 350, at the end of the corresponding through groove 351 away from the counting wheel 341, a first sensor 352 is provided. The first sensor 352 is facing the center of the corresponding V-shaped guide plate 350. The first sensor 352 is an image sensor or an infrared sensor. The first sensor 352 is used to record the number of connecting rings 6 passing through. When the second drive motor drives the counting rod 342 to rotate and makes the counting rod 342 pass through the corresponding through groove 351, the second drive motor stops. At this time, the counting rod 342 that has just passed through the through groove 351 is parallel to the V-shaped guide plate 350, and the connecting ring 6 will move to the outside of the counting rod 342, that is, the connecting ring 6 will be fitted on the outside of the counting rod 342. The first sensor 352 will record the number of connecting rings 6 fitted on the counting rod 342. When the number of connecting rings 6 reaches ten, the second drive motor drives the counting rod 342 to continue to rotate until the next counting rod 342 passes through the through groove 351.

[0043] refer to Figure 4Below the multiple V-shaped guide plates 350, at the end of the corresponding through groove 351 away from the counting wheel 341, there are stop bars 360. The lower ends of the multiple stop bars 360 are fixedly mounted on a horizontal third rotating shaft 361. The two ends of the third rotating shaft 361 are respectively rotatably mounted on two crossbars 311. One end of the third rotating shaft 361 is connected to a third drive motor, which is a stepper motor or a servo motor. The third drive motor can rotate forward and reverse at a fixed angle under program control. The third drive motor can drive the stop bars 360 to rotate through the third rotating shaft 361. The stop lever 360 is used to prevent the connecting ring 6 from moving. When the second drive motor drives the counting rod 342 to rotate, the program controls the third drive motor to drive the third rotating shaft 361 to rotate counterclockwise, so that the stop lever 360 rotates into the V-shaped guide plate 350. At this time, the stop lever 360 is perpendicular to the V-shaped guide plate 350, and the stop lever 360 will prevent the connecting ring 6 from moving. When the counting rod 342 stops rotating, the program controls the third drive motor to drive the third rotating shaft 361 to rotate clockwise, so that the stop lever 360 rotates and moves out of the V-shaped guide plate 350, and the connecting ring 6 can continue to move.

[0044] refer to Figure 2 A discharge hopper 370 is provided at the end of the support frame 310 away from the feed hopper 320. The discharge hopper 370 is located below multiple counting structures 340. The two ends of the discharge hopper 370 are fixedly connected to the vertical rods 312 on both sides. The lower end of the discharge hopper 370 is connected to the packaging device 4, so that the connecting rings 6 after being counted by multiple counting structures 340 will simultaneously enter the packaging device 4 through the discharge hopper 370 for packaging. A second sensor (not shown in the figure) is provided inside the discharge hopper 370. The second sensor is an image sensor. The second sensor is used to record the number of times the connecting rings 6 fall. When the connecting rings 6 fall ten times, the corresponding packaging bag in the packaging device 4 will contain 1000 connecting rings 6. At this time, the packaging bag sealing structure will be controlled to seal the packaging bag.

[0045] refer to Figure 2 The tilt angles of the aforementioned rotating drum 330 and V-shaped guide plate 350 are both 1° to 3°, which allows the connecting ring 6 to move along the rotating drum 330 and V-shaped guide plate 350 under the action of gravity and vibration, and prevents the connecting ring 6 from flipping over on its own during the movement.

[0046] In summary, the working principle of the counting device 3 is as follows: When the counting device 3 is in use, the connecting ring 6 inside the feed hopper 320 will enter the ten rotating drums 330 through the feed hopper 320. The rotating drums 330 will drive the internal connecting ring 6 to rotate, causing the connecting ring 6 to flip until its axis is parallel to the axis of the rotating drum 330. At this time, the connecting ring 6 will maintain the state of parallel axis with the axis of the rotating drum 330 and continue to move towards the counting structure 340. When the counting rod 342 is in a state parallel to the V-shaped guide plate 350, the connecting ring 6 will be fitted onto the counting rod 342. The first sensor 352 will record the number of connecting rings 6 fitted onto the counting rod 342. When all ten counting structures 340 have ten connecting rings 6 mounted on their technical rods, the second drive motor will rotate the counting rods 342 until the corresponding ten counting rods 342 tilt toward the discharge hopper 370. The connecting rings 6 on the ten counting structures 340 will fall into the discharge hopper 370 at the same time. Since each of the ten counting rods 342 has ten connecting rings 6 mounted on it, the number of connecting rings 6 falling into the discharge hopper 370 each time is 100. The second sensor will record the number of times the connecting rings 6 fall. When the connecting rings 6 fall 10 times, the packaging bag will contain 1000 connecting rings 6. At this time, the packaging bag sealing structure will seal the packaging bag.

[0047] The packaging process flow of the above-mentioned connecting ring 6 packaging equipment is as follows: [1] Set relevant parameters for packaging bags and products on controller 5. The relevant parameters include the length and size of the packaging bag, the quantity of products packaged each time, the content of the printed label, and the spacing of the vent holes on the packaging film. [2] The packaging film is installed on the packaging film feeding structure of the packaging device, and the packaging film is installed in rolls; [3] Start the packaging equipment; the equipment will run automatically under program control: The elevator transports the products in the storage hopper to the counting device, which calculates the number of products passing through. The packaging device prints a label on the packaging film, punches vent holes in the packaging film, cuts the packaging film and seals one end, forming a packaging bag with one open end. After the calculated number of products enters the packaging bag, the packaging device seals the other end of the packaging bag. [4] Product packaging is completed and the material is discharged.

[0048] This technical solution, through the configuration of a storage hopper, elevator, counting device, packaging device, and controller, enables the controller to automatically transport the products in the storage hopper to the counting device via a program after parameter settings are completed. The counting device automatically counts the products and sends them to the packaging device, which automatically labels the products and seals them. The entire process requires only one worker to set parameters and install the packaging film, thus achieving automated production of product packaging. This improves the production efficiency of connecting ring packaging, reduces the labor intensity of workers, and saves labor costs.

[0049] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
