Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a sock opening mechanism. Background Technology

[0002] In the sock production process, after each pair of socks is packaged (in small bags), multiple packages are neatly arranged and placed into larger packaging bags to form a complete package (large bag) for easy shipping. Initially, our company used manual packaging for these large bags, requiring at least two skilled workers per packaging line. This method was inefficient and labor-intensive. We later added an automatic bag-opening device adapted for sock packaging, but this had the following problems: While the automatic bag-opening device uses suction cups to open the bag opening on the vacuum conveyor belt, this resulted in a small opening, and sometimes the back of the bag remained closed. This made it difficult to insert thicker socks, potentially causing them to shift during loading and affecting the neatness of the packaged socks. Therefore, a bag-opening mechanism that can open the packaging bag and facilitate the insertion of socks is needed. Utility Model Content

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] In the attached diagram, all identical reference numerals refer to the same components.

[0019] Example 1: like Figure 2 , 4 As shown in Figure 6, this utility model provides a sock bag opening mechanism including a base 1 and a suction conveying mechanism 2. The suction conveying mechanism 2 is located at the top of the base 1. A pushing component is provided at the top of the base 1. The pushing component is connected to the side wall of the suction conveying mechanism 2, and a bag opening component 6 is provided above it to open the packaging bag through the pushing component. The suction conveyor 2 adopts existing technology, which uses strong suction to adsorb the packaging bag onto the conveyor belt with air holes, so that the packaging bag does not move. The suction conveyor 2 in the attached figure also extends to the subsequent work station. Therefore, a part of the suction conveyor 2 is shown in the attached figure of this application.

[0020] Furthermore, the pushing assembly includes a platform 3, a clamping unit 4, a pushing unit 5, and a spreading unit 10. The platform 3 is horizontally disposed on an outer side wall of the suction conveying mechanism 2, and its top end is flush with the top end of the conveyor belt of the suction conveying mechanism 2. The clamping unit 4 and the pushing unit 5 are both disposed on the platform 3. The pushing unit 5 is connected to the clamping unit 4 in a transmission manner to push the clamping unit 4 toward the packaging bag. The spreading unit 10 is disposed on the platform 3 and located between the platform 3 and the clamping unit 4 to spread the packaging bag open.

[0021] When the packaging bag on the suction conveyor 2 is transported to the bottom of the bag opening component 6, the bag opening component 6 sucks up the bag opening and lifts it to open the bag opening. After the bag opening is opened, the bag opening unit 10 makes the packaging bag open more completely. Then, the clamping unit 4 fixes the socks and the pushing unit 5 pushes the socks into the packaging bag.

[0022] Furthermore, the bag opening assembly 6 includes a first gantry 61, a first mounting bracket 62, a third cylinder 63, a second optical axis 64, and at least two first vacuum suction cups 65. The first gantry 61 is located at the top of the base 1 and above the platform 3. The first mounting bracket 62 is located inside the first gantry 61 and above the connection between the suction conveying mechanism 2 and the platform 3. The third cylinder 63 is located in the middle of the top of the first gantry 61, and its piston rod is vertically downward and fixedly connected to the first mounting bracket 62. At least two first vacuum suction cups 65 are arranged at intervals at the bottom of the first mounting bracket 62.

[0023] Specifically, the first vacuum suction cup 65 is connected to an external vacuum pump using existing technology through a pipeline. The third cylinder 63 on the first gantry 61 drives the first mounting frame 62 to move vertically downward until the first vacuum suction cup 65 at the bottom of the first mounting frame 62 contacts the outside of the bag opening of the packaging bag on the suction conveying mechanism 2. After the first vacuum suction cup 65 sucks the outside of the bag opening of the packaging bag, the third cylinder 63 drives the first mounting frame 62 to move vertically upward, so that the first vacuum suction cup 65 opens the bag opening of the packaging bag. After the socks are sent into the packaging bag, the first vacuum suction cup 65 releases the bag opening of the packaging bag. The second optical axis 64 can increase the stability of the first mounting bracket 62 when it moves; If only two first vacuum suction cups 65 are set, they are set on the left and right sides of the first mounting bracket 62. If three first vacuum suction cups 65 are set, two of them are set on the left and right sides of the first mounting bracket 62, and the other is set near the center of the first mounting bracket 62. The number of first vacuum suction cups 65 can also be set according to actual needs.

[0024] Furthermore, the clamping unit 4 includes a receiving plate 41, a clamping plate 42, and a first cylinder 43. The platform 3 has a through groove 31 perpendicular to the direction of the suction conveying mechanism 2. The receiving plate 41 is located at one end of the platform 3 near the suction conveying mechanism 2, and at the other end away from the suction conveying mechanism 2, there is a push plate 44 located in the through groove 31 and connected to the pushing unit 5. The clamping plate 42 is located above the receiving plate 41 away from the suction conveying mechanism 2. The first cylinder 43 is located at the bottom end of the receiving plate 41, and its piston rod is vertically upward and connected to the clamping plate 42 to drive the clamping plate 42 to clamp the sock.

[0025] Specifically, the socks are neatly placed onto the receiving plate 41 by a transfer device (which may be a robotic arm). After placement, the piston rod of the first cylinder 43 retracts, causing the clamping plate 42 to move toward the receiving plate 41, thereby fixing the socks onto the receiving plate 41. Then, the pushing unit 5 pushes the socks into the packaging bag. After that, the first cylinder 43 drives the clamping plate 42 to reset, thereby releasing the socks. Then, the pushing unit 5 resets the receiving plate 41, leaving the socks inside the packaging bag. The push plate 44 is adapted to the through slot 31, so that the push plate 44 can move within the through slot 31 when driven by the push unit 5.

[0026] Furthermore, the pushing unit 5 includes a second cylinder 51 and a first optical axis 52. The second cylinder 51 is located at the bottom end of the platform 3, and its piston rod is horizontally arranged in the direction of the suction conveying mechanism 2 and fixedly connected to the push plate 44. The first optical axis 52 is horizontally arranged in the through groove 31 and is located on the side of the piston rod of the second cylinder 51, and both are slidably connected to the push plate 44.

[0027] Specifically, after the socks are secured, the second cylinder 51 pushes the socks into the opened packaging bag. After the socks are placed in the packaging bag, the second cylinder 51 drives the clamping unit 4 to reset. The first optical axis 52 is used to increase the stability of the clamping unit 4 when it is pushed. There are usually two first optical axes 52, which are located on both sides of the second cylinder 51 respectively.

[0028] Example 2: like Figure 2 , 4 As shown, the expansion unit 10 has two servo motors 101 and two expansion plates 102. The two expansion plates 102 are rotatably located on both sides of the top of the platform 3, and the spacing between them is adapted to the opening size of the packaging bag. The two servo motors 101 are located at the bottom of the platform 3, and their output shafts are fixedly connected to the two expansion plates 102 respectively.

[0029] Specifically, two servo motors 101 using existing technology are set at the bottom of the platform 3, and drive the corresponding expansion plate 102 to further open the packaging bag after the bag opening is opened, and form a guide plate through the two expansion plates 102 to facilitate the socks being pushed into the packaging bag; The bottom ends of both support plates 102 have gaps with the top of the platform 3 to prevent the servo motor 101 from interfering with the inside of the packaging bag when driving the corresponding support plate 102 to rotate, which would cause the packaging bag to deform or break, thus affecting the bagging process.

[0030] Example 3: like Figure 1 , 3As shown in Figure 4, the system includes a frame 7, which is located at the top of the base 1 and on the feeding side of the suction conveying mechanism 2. A belt conveying mechanism 71 parallel to the suction conveying mechanism 2 is installed inside the frame 7. A translation component 8 is provided at the top of the base 1, and an adsorption component 9 is provided on the translation component 8.

[0031] A first support plate 72 is provided between the two conveyor belts of the belt conveyor mechanism 71 and is connected to the front and rear of the frame 7. A second support plate 73 is provided on both sides of the first support plate 72 and is connected to the side wall of the frame 7.

[0032] Specifically, the belt conveyor 71 is a dual-belt conveyor using existing technology, which transports the stacked packaging bags toward the suction conveyor 2. The first support plate 72, which is set between the two conveyor belts, supports the middle part of the packaging bag, and the second support plates 73 on both sides support the front and rear ends of the packaging bag.

[0033] Furthermore, the translation component 8 includes a linear screw guide rail 81, an optical axis guide rail 82, and a second gantry 83. The linear screw guide rail 81 and the optical axis guide rail 82 are located on the left and right sides of the base 1. One end of the second gantry 83 is fixedly connected to the movable seat of the linear screw guide rail 81, and the other end is slidably connected to the optical axis of the optical axis guide rail 82.

[0034] The adsorption assembly 9 includes a second mounting frame 91, a fourth cylinder 92, four third optical axes 93, and at least four second vacuum suction cups 94. The second mounting frame 91 is located inside the second gantry 83, and its two sides are located above the two conveyor belts of the belt conveyor mechanism 71. The fourth cylinder 92 is located in the middle of the top of the second gantry 83, and its piston rod is vertically downward and fixedly connected to the second mounting frame 91. The four third optical axes 93 are arranged in a rectangular array at the top of the second mounting frame 91 and are all slidably connected to the second gantry 83. At least four second vacuum suction cups 94 are respectively located at the four corners of the second mounting frame 91.

[0035] Specifically, the linear screw guide rail 81 can drive the second gantry 83 to move from the belt conveyor mechanism 71 to the suction conveyor mechanism 2, or vice versa, thereby driving the adsorption component 9 on the second gantry 83 to move back and forth between the belt conveyor mechanism 71 and the suction conveyor mechanism 2. The bottom of both the linear screw guide rail 81 and the optical axis guide rail 82 is equipped with a raised frame. The second vacuum suction cup 94 is connected to an external vacuum pump using existing technology via a pipeline. When the adsorption assembly 9 is on the belt conveyor mechanism 71, the piston rod of the fourth cylinder 92 extends to drive the second mounting frame 91 to move downward until the suction cup contacts the top of the stacked packaging bag. After the four second vacuum suction cups 94 hold the four corners of the packaging bag, the fourth cylinder 92 drives the second mounting frame 91 to move upward. Then, the second gantry 83 is moved to the suction conveyor mechanism 2 via the linear screw guide rail 81 and the optical axis guide rail 82. The fourth cylinder 92 drives the second mounting frame 91 to move downward until the packaging bag contacts the surface of the suction conveyor mechanism 2. After that, the second vacuum suction cups 94 release the packaging bag. Repeating the above steps can continuously transfer the packaging bag from the belt conveyor mechanism 71 to the suction conveyor mechanism 2. The third optical axis 93 can increase the stability of the second mounting bracket 91 when it moves.

[0036] Example 4: The second mounting frame 91 is X-shaped. Multiple partitions 74 are provided on the surfaces of the two conveyor belts of the belt conveyor mechanism 71. The spacing between each partition 74 is adapted to the size of the packaging bag. Each second support plate 73 has a baffle 75 at its top.

[0037] Specifically, the X-shaped second mounting bracket 91 reduces weight, and both the partition 74 and the baffle 75 serve to limit the position of the packaging bag.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
