Description

Technical Field

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

[0002] In the traditional production process of packaging bags, after the packaging bags are produced by the bag making machine, they are manually counted, stacked, sorted, packaged and bundled. This has high production costs and low production efficiency, and it is difficult to ensure the counting accuracy and sorting and bundling effects.

[0003] The applicant of the utility model has previously applied for several patents for automatic stacking, sorting, packaging and bundling of sheet materials, for example: the prior patent with application number CN201810962109.1, which sets a primary transmission mechanism, a stacking and sorting mechanism, a continuous receiving mechanism, a secondary transmission mechanism, a tertiary transmission mechanism and a bundling mechanism, and uses the continuous receiving mechanism to continuously receive and stack the sheet materials into stacks, and uses the stacking and sorting mechanism to sort the sheet materials during the stacking process, and then transports them to the bundling mechanism through the secondary transmission mechanism and the tertiary transmission mechanism to complete the bundling, thereby realizing fully automatic, continuous and non-stop stacking, sorting, packaging and bundling, reducing manual operations, improving production efficiency and reducing production costs.

[0004] The above-mentioned prior patents have not yet completed the last step of automated stacking and bundling of packaging bags, that is, how to stack the bundled packaging bags, arrange them into several rows, columns and layers, and then pack them. To this end, the applicant of the utility model applied for a patent with application number CN202210147745.5 and the name of "Multi-layer stacking device for packaging bags". The patent first uses a longitudinal transmission mechanism to longitudinally transport the packaging bag stacks into a single row, and then uses a transverse transmission mechanism to transversely transport the single-row packaging bag stacks, and then falls to the stacking transmission mechanism to stack them into multiple layers, and finally transports the single-row packaging bag stacks stacked into multiple layers to the output platform horizontally, so that the packaging bag stacks are arranged in multiple rows.

[0005] However, the stacking method of the above-mentioned packaging bag multi-layer stacking device, which first arranges single-row multi-layers and then arranges multi-layer multi-rows, is still not simple and efficient enough, and the single-row packaging bag stacks stacked into multiple layers are prone to scatter during the lateral transportation process.

[0027] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is further described below in conjunction with the accompanying drawings.

[0028] The longitudinal direction of the utility model refers to the conveying direction of the bundled packaging bag stacks into the arrangement platform, and the packaging bag stacks are arranged in a single row along the longitudinal direction; the transverse direction is perpendicular to the longitudinal direction, and the packaging bag stacks are arranged in multiple rows along the transverse direction.

[0029] The connection described in the utility model refers to the contact or proximity between the two mechanisms, so that the packaging bag of the upstream mechanism can be smoothly transported to the downstream mechanism.

[0030] like Figures 1 to 3 A packaging bag stacking device is shown, which includes a single-row arrangement platform, a single-layer stacking mechanism and a multi-layer stacking output platform.

[0031] The single-row arrangement platform includes a longitudinal transmission mechanism 1, a transverse transmission mechanism 2 and an arrangement lifting mechanism; the transmission directions of the longitudinal transmission mechanism 1 and the transverse transmission mechanism 2 are perpendicular to each other, and the longitudinal transmission mechanism 1 and the transverse transmission mechanism 2 are intersecting; the arrangement lifting mechanism is used to drive the longitudinal transmission mechanism 1 to rise and fall in the gap of the transverse transmission mechanism 2. Of course, the arrangement lifting mechanism can also be used to drive the transverse transmission mechanism to rise and fall in the gap of the longitudinal transmission mechanism.

[0032] As one of the structural forms of the longitudinal transmission mechanism 1 and the transverse transmission mechanism 2, the transverse transmission mechanism 2 is a belt conveyor, which includes conveyor belts arranged in parallel and at intervals, and the gaps of the transverse transmission mechanism 2 are the gaps between the conveyor belts; the longitudinal transmission mechanism 1 is a roller conveyor, which includes rollers arranged in parallel and at intervals, and the gaps of the longitudinal transmission mechanism 1 are the gaps between the rollers; the conveyor belt is arranged in the gaps between the rollers.

[0033] Of course, the longitudinal transmission mechanism and the transverse transmission mechanism can also be interchanged in structure: the longitudinal transmission mechanism is a belt conveyor, the belt conveyor includes conveyor belts arranged in parallel and spaced apart, and the gaps of the longitudinal transmission mechanism are the gaps between the conveyor belts; the transverse transmission mechanism is a roller conveyor, the roller conveyor includes rollers arranged in parallel and spaced apart, and the gaps of the transverse transmission mechanism are the gaps between the rollers; the conveyor belt is arranged in the gaps between the rollers.

[0034] The arrangement lifting mechanism can be various conventional lifting mechanisms such as a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism. In this embodiment, a cylinder (not shown in the figure) is used.

[0035] The longitudinal transmission mechanism 1 and the transverse transmission mechanism 2 can be transmission mechanisms with active transmission power or without active transmission power, and the stack of packaging bags is pushed by the thrust of an external mechanism to be transported on the longitudinal transmission mechanism or the transverse transmission mechanism.

[0036] The multi-layer stacking and outputting platform 3 is used for stacking multi-layer packaging bags and conveying the stacked multi-layer packaging bags. The multi-layer stacking and outputting platform 3 comprises a material conveying mechanism.

[0037] The single-layer stacking mechanism includes a stacking fork arm 6, a stacking baffle 4, a stacking telescopic mechanism 7 and a stacking lifting mechanism 8. The stacking baffle 4 is vertically arranged on one side of the multi-layer stacking output platform 3. The stacking baffle 4 is provided with a vertical slot for the stacking fork arm 6 to pass through. The stacking telescopic mechanism 7 is used to drive the stacking fork arm 6 to pass through the stacking baffle 4 and extend into the top of the multi-layer stacking output platform 3 and to be retracted from the top of the multi-layer stacking output platform 3. The stacking lifting mechanism 8 is used to drive the stacking fork arm 6 to move up and down.

[0038] In order to reduce the resistance when the stack of packaging bags is arranged on the stacking fork arm 6, a rotatable roller 9 is provided on the stacking fork arm 6.

[0039] The stacking fork arm 6 is installed on the stacking fork arm mounting plate 11 through the fork arm pad 10. The fork arm pad 10 raises the stacking fork arm 6 to facilitate the stacking fork arm 6 to avoid other mechanisms during telescopic movement, and can be lifted to a position basically flush with the upstream transmission mechanism.

[0040] The moving end of the stacking telescopic mechanism 7 is connected to the stacking fork arm mounting plate 11. The stacking telescopic mechanism 7 can be various conventional reciprocating motion mechanisms such as a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism. In this embodiment, a motor belt transmission mechanism is used.

[0041] The stacking lifting mechanism 8 can be any conventional lifting mechanism such as a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism. In this embodiment, a motor belt transmission mechanism is used.

[0042] If no transition transmission mechanism is provided, the discharge end of the transverse transmission mechanism 2 is directly connected to the top of the multi-layer stacking output platform 3. However, in order to facilitate the mechanism arrangement, in this embodiment, the packaging bag stacking device further includes a transition transmission mechanism 12, the discharge end of the transverse transmission mechanism 2 is connected to the feed end of the transition transmission mechanism 12, the discharge end of the transition transmission mechanism 12 is connected to the top of the multi-layer stacking output platform 3, the stacking baffle 4 is vertically arranged below the discharge end of the transition transmission mechanism 12, and the stacking telescopic mechanism 7 and the stacking lifting mechanism 8 are arranged below the transition transmission mechanism 12.

[0043] In order to increase the power when the packaging bag stacks are arranged on the stacking fork arm 6 and avoid jamming when there are too many packaging bag stacks arranged on the stacking fork arm 6, the transition transmission mechanism 12 is also provided with a stacking pushing mechanism, which is used to push materials from the transition transmission mechanism 12 toward the stacking fork arm 6 in the horizontal direction.

[0044] like Figure 3 As shown, the stacking pushing mechanism includes a pushing plate 13, a pushing plate reciprocating mechanism 14 and a pushing plate lifting mechanism 15. The pushing plate reciprocating mechanism 14 is used to drive the pushing plate 13 to reciprocate in the lateral direction, and the pushing plate lifting mechanism 15 is used to drive the pushing plate 13 to move up and down. The pushing plate reciprocating mechanism 14 and the pushing plate lifting mechanism 15 can be various conventional reciprocating mechanisms such as a cylinder, a hydraulic cylinder, an electric cylinder, a gear rack transmission mechanism or a linear motor. In this embodiment, cylinders are used. When the stack of packaging bags passes through, the pushing plate 13 rises; after the stack of packaging bags passes through, the pushing plate 13 is lowered and pushes the stack of packaging bags toward the stacking fork arm 6.

[0045] like Figures 4 to 6 The process of multi-layer stacking of packaging bags shown includes the following steps:

[0046] (1) The packaging bag stack 16 is bundled by the bundling mechanism, and the bundled packaging bag stack 16 is sent to the single-row arrangement platform. The longitudinal transmission mechanism 1 longitudinally transports the packaging bag stack 16 into a single row (a single-row packaging bag stack ≥ one stack of packaging bags), such as Figure 4 As shown;

[0047] (2) The arrangement lifting mechanism drives the longitudinal conveying mechanism 1 to descend, and the single-row packaging bag stacks 16 are transferred to the transverse conveying mechanism 2, and then transported in the transverse direction by the transverse conveying mechanism 2. After passing through the transition conveying mechanism 12, the single-row packaging bag stacks 16 are arranged on the stacking fork arm 6 in a single-layer multi-row state, as shown in FIG. Figure 5 As shown;

[0048] (3) After the stacking fork arm 6 is lowered, it is retracted from above the multi-layer stacking output platform 3, and the single-layer multi-row packaging bag stacks 16 are stacked layer by layer on the multi-layer stacking output platform 3, thereby realizing multi-layer stacking of the packaging bag stacks, such as Figure 6 shown.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
