Description

Technical Field

[0001] The utility model relates to the technical field of ziplock bag palletizing, in particular to a ziplock bag palletizing device. Background Art

[0002] Ziplock bags, also known as dense bags, bone bags, sealed bags, zipper bags, keel bags, are a type of plastic bag that can be repeatedly sealed, made of polyethylene LDPE and high-pressure linear polyethylene LLDPE blown film, and hot-cut machine bags. Because there is a sealing strip at the sealing point of the ziplock bag, when the ziplock bag is flattened, the thickness of one end with the sealing strip is thicker and the other end is thinner. Therefore, when the ziplock bags are processed and stacked, the height of the ziplock bags cannot be too high, otherwise it will be difficult to pack the stack of ziplock bags later. In addition, after packing, the stack of ziplock bags will not appear neat and beautiful. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a ziplock bag stacking device, which can adjust the stacking direction of the ziplock bags.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0019] like Figure 1 As shown, this embodiment provides a ziplock bag stacking device, including a first stacking structure 1, a stopping mechanism 2, and a second stacking structure 3.

[0020] Specifically, Figure 1 , Figure 3 As shown, the first stacking structure 1 is arranged at the rear end of the conveyor platform 4, including a turntable 11 and a tray 12. The tray 12 is arranged on the top of the turntable 11. A motor is arranged inside the turntable 11 for rotating the tray 12 180°. The tray 12 is arranged as a U-shaped structure, including a bottom plate 121 and two side plates 122 arranged on the top of the bottom plate. The tray 12 is used to receive the ziplock bags conveyed by the conveyor platform 4.

[0021] Specifically, Figure 1 , Figure 2As shown, the first stacking structure 1 is located between the stopping mechanism 2 and the conveying platform 4. The stopping mechanism 2 includes a lifting assembly 21 and a baffle 22. The lifting assembly 21 is vertically arranged on the gantry 23, and the movable end at the bottom thereof is connected to the baffle 22. The lifting assembly 21 is used to adjust the height of the baffle 22. There are many ways to implement the lifting assembly 21, such as using a lifting rod driven by a cylinder, an oil cylinder or a hydraulic pressure. The baffle 22 is close to the pallet 12. When the ziplock bag falls into the pallet 12, the baffle 22 is used to stop the ziplock bag.

[0022] Specifically, Figure 1 , Figure 2 As shown, the second stacking structure 3 includes two limit plates 31, a stopper 32, a flat plate 33 and a telescopic assembly 34. Two legs 41 are arranged on each side of the conveying platform 4. The outer wall of the limit plate 31 is fixedly arranged on the support frame 311. The support frame 311 is connected to the gantry 23. The limit plate 31 is located at the top of the corresponding side plate 122. The bottom surface of the limit plate 31 is close to the top surface of the side plate 122. The inner wall of the limit plate 31 and the inner wall of the side plate 122 are located in the same vertical plane. The telescopic assembly 34 and the flat plate 33 are both located below the conveying platform 4. The telescopic assembly 34 is horizontally arranged on the support plate 341. Both ends of the support plate 341 are connected to the corresponding legs 41. The movable end of the telescopic assembly 34 is connected to the flat plate 33, so as to make the flat plate 33 moves between the two limit plates 31. There are many ways to implement the telescopic component 34, such as using a telescopic rod driven by a cylinder, an oil cylinder or a hydraulic pressure. When the flat plate 33 moves between the two limit plates 31, the flat plate 33 is used to receive the ziplock bag transported by the conveyor platform 4. The baffle 32 is connected to the limit plate 31, and the baffle 32 is located at the end of the limit plate 31 facing the conveyor platform 4. The baffle 32 cannot hinder the moving trajectory of the flat plate 33. When the flat plate 33 retracts to the bottom of the conveyor platform 4, the baffle 32 is used to retain the ziplock bag on the flat plate 33 in the pallet 12. Note: the baffle 22 is also close to the two limit plates 31. When the ziplock bag falls into the flat plate 33, the baffle 22 is used to stop the ziplock bag.

[0023] The method of use is as follows: the conveyor 4 conveys the ziplock bags to the tray 12 in sequence. When the ziplock bags reach a preset height, the telescopic component 34 is used to move the flat plate 33 between the two limit plates 31, and the flat plate 33 temporarily receives the ziplock bags conveyed by the conveyor 4; then the lifting component 21 is used to move the baffle 22 upward. The upward position of the baffle 22 needs to meet two points: it is separated from the tray 12, but still close to the two limit plates 31; when the baffle 22 moves up to the preset position, the turntable 11 is used to rotate the tray 12 180°; then the lifting component 21 is used to move the baffle 22 down to its original position, and the baffle 22 is close to the tray 12 and the two limit plates 31; the telescopic component 34 is used to retract the flat plate 33 to its original position. During this process, the baffle 32 causes the ziplock bags on the flat plate 33 to be trapped in the tray 12; the ziplock bags conveyed by the conveyor 4 continue to fall into the tray 12, and the ziplock bags newly falling into the tray 12 are in the opposite direction to the ziplock bags of the previous batch falling into the tray 12. Through the above-mentioned method, this embodiment solves the problem of large thickness difference between the two ends of the ziplock bags when they are stacked.

[0024] More specifically, in order to improve the stability of the plate 33 during movement and ensure that the stopper 32 does not hinder the movement trajectory of the plate 33, the present embodiment adopts the following measures: Figure 2 , Figure 4 , Figure 5 As shown, the blocking member 32 includes a horizontal bar 321 and two blocking bars 322 arranged on the top thereof. The end of the horizontal bar 321 is connected to the limiting plate 31. The bottom surface of the horizontal bar 321 is higher than the top surface of the side plate 122. A plurality of strip grooves 331 are provided at one end of the flat plate 33 facing the baffle 22. The two blocking bars 322 are located in the corresponding two strip grooves 331. The bottom surface of the flat plate 33 is close to the horizontal bar 321, and the horizontal bar 321 plays a role in supporting the flat plate 33.

[0025] More specifically, in order to facilitate the use of a robotic arm to take out the stacked ziplock bags in the tray 12, the present embodiment adopts the following measures: Figure 3 As shown, a bearing plate 13 is provided on the top of the turntable 11, and the bottom plate 121 includes a plurality of arrays of strip plates, and the end of each strip plate is fixedly mounted on the top of the bearing plate 13 through a vertical plate 14, and an avoidance groove is provided between two adjacent strip plates.

[0026] The method of use is as follows: when the stacked ziplock bags in the tray 12 reach the height that needs to be taken out, the lifting assembly 21 is used to move the baffle 22 upward. After the baffle 22 is separated from the tray 12, one clamp of the robot arm is inserted under the bottom plate 121 through the avoidance groove, and at the same time, the other clamp moves to the top of the ziplock bag, and all the ziplock bags are taken out by clamping the two clamps.

[0027] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
