A stacking machine for corrugated cardboard box production

Abstract

This invention discloses a stacking machine for corrugated cardboard box production, comprising a base and multiple cardboard boxes; a drive assembly; a rotating assembly; a pushing assembly; a flipping assembly; a reciprocating lifting assembly; a leveling assembly; and a lifting baffle. When the grooved wheel rotates 360°, two cardboard boxes in an L-shape are present on each side of the roller bed. Simultaneously, the grooved wheel drives the flipping assembly to rotate 180°, flipping the two L-shaped cardboard stacks. At the same time, the flipping assembly drives the leveling assembly to push the L-shaped cardboard box on one side of the roller bed to merge with the L-shaped cardboard box on the other side of the roller bed, forming a U-shaped cardboard stack. The reciprocating lifting assembly continues to slide to one side, and the upper U-shaped cardboard stack falls down and stacks with the lower U-shaped cardboard stack. At this time, the flipping assembly is located below the roller bed. When the grooved wheel rotates 360° again, the L-shaped cardboard stack does not flip, allowing the upper U-shaped cardboard stack to be stacked with the lower U-shaped cardboard stack in a staggered manner. The above movement is repeated to perform a U-shaped staggered stacking, which improves the stability of the cardboard stack to a certain extent.

Description

Technical Field

[0001] This invention relates to the field of cardboard box stacking technology, specifically a stacking machine for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading. Finished corrugated boxes need to be stacked using a stacking machine to ensure orderly stacking and reduce floor space.

[0003] Stacking methods are mostly divided into overlapping stacking, cross-stacking stacking, and zigzag stacking. Among them, the zigzag stacking has higher stability, but it is more difficult to stack. Most existing stacking machines for corrugated cardboard box production require the use of robotic arms for zigzag stacking. Since the corrugated cardboard box itself is relatively fragile, the robotic arm is prone to causing physical damage to the cardboard box during the clamping process, which increases production costs and reduces production efficiency to a certain extent. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above and / or existing stacking machines for corrugated cardboard box production, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a stacking machine for corrugated cardboard box production. During operation, the drive assembly drives the roller bed to move, transporting the cardboard boxes to the top of the platform. Simultaneously, the drive assembly drives the rotating block to rotate. Every 360° rotation of the rotating block causes the grooved wheel to rotate intermittently by 90° through the cooperation of the first and second arc-shaped protrusions and the first protrusion and the first groove. Each time the grooved wheel rotates 90°, it drives the pushing assembly to sequentially push the cardboard boxes on the top of the platform to both sides of the roller bed. When the grooved wheel rotates 360°, there are two cardboard boxes in an L-shape on each side of the roller bed. At the same time, the grooved wheel drives the flipping assembly to rotate 180°, flipping the two sets of L-shaped cardboard stacks. Simultaneously, the reciprocating lifting component rises first, and as it rises, it causes the lifting baffle to descend. Under the action of the roller bed, the L-shaped paper stacks on both sides are pushed to one end of the roller bed. At the same time, the flipping component drives the leveling component to push the L-shaped cardboard box on one side of the roller bed to merge with the L-shaped cardboard box on the other side of the roller bed, forming a U-shaped paper stack. The reciprocating lifting component continues to slide to one side, and the upper U-shaped paper stack falls down and stacks with the lower U-shaped paper stack. At this time, the flipping component is located below the roller bed. When the groove wheel rotates 360° again, the L-shaped paper stack does not flip, so that the upper U-shaped paper stack and the lower U-shaped paper stack are stacked in a staggered manner. The above movement is repeated to perform U-shaped staggered stacking, which improves the stability of the paper stack to a certain extent.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figures 1-9 This invention provides a stacking machine for corrugated cardboard box production, comprising:

[0041] The base 1 and multiple cartons 7 are provided. A roller bed 2 is fixedly connected to the top of the base 1. A platform 45 is provided on one side of the center of the roller bed 2. The cartons 7 are transported to the top of the platform 45 under the action of the roller bed 2.

[0042] The drive assembly is installed on one side of the roller bed 2 and drives the roller bed 2 to run.

[0043] A rotating assembly, installed inside the base 1 and connected to the drive assembly, intermittently rotates the carton 7 by 90°. The rotating assembly includes:

[0044] A lever 25 is provided with a first arc-shaped protrusion 48 on one side and a first protrusion 49 on the top of one end of the lever 25. A grooved wheel 39 is fixedly connected to the bottom of the platform 45. Multiple first grooves 50 are provided at the bottom of the grooved wheel 39. Multiple second arc-shaped protrusions 51 are provided at the bottom of the grooved wheel 39. A first irregular gear 53 is fixedly connected to the bottom of the grooved wheel 39. The bottom of the first irregular gear 53 is movably connected to the bottom of the inner side of the base 1.

[0045] The pushing component is installed inside the base 1 and connected to the rotating component to push the rotated carton 7.

[0046] The flipping component, installed inside the roller bed 2 and connected to the rotating component, intermittently flips the pushed-out carton 7.

[0047] The reciprocating lifting component is installed inside the base 1 and is connected to the flipping component, enabling the integrated carton 7 to repeatedly perform upward and downward movements.

[0048] A leveling component, mounted on one side of the roller bed 2 and connected to the flipping component, pushes multiple cartons 7 located on one side of the roller bed 2 to integrate them;

[0049] The lifting baffle 8 is installed in the middle of the roller bed 2 and is connected to the reciprocating lifting assembly.

[0050] Specifically, the drive assembly drives the roller bed 2 to move, transporting the cartons 7 to the top of the platform 45. Simultaneously, the drive assembly rotates the lever 25. Every 360° rotation of the lever 25 causes the grooved wheel 39 to rotate intermittently by 90° through the cooperation of the first arc-shaped protrusion 48 and the second arc-shaped protrusion 51, and the first protrusion 49 and the first groove 50. Each 90° rotation of the grooved wheel 39 drives the pushing assembly to sequentially push the cartons 7 from the top of the platform 45 to both sides of the roller bed 2. When the grooved wheel 39 has rotated 360°, there are two cartons in an L-shape on each side of the roller bed 2. At the same time, the grooved wheel 39 drives the flipping assembly to rotate 180°, flipping the two L-shaped cartons. The flipping assembly also... The reciprocating lifting component rises first, driving the lifting baffle 8 to descend. Under the action of the roller bed 2, the L-shaped paper stacks on both sides are pushed to one end of the roller bed 2. At the same time, the flipping component drives the leveling component to push the L-shaped cardboard box on one side of the roller bed 2 to merge with the L-shaped cardboard box on the other side of the roller bed 2, forming a U-shaped paper stack. The reciprocating lifting component continues to slide to one side, and the upper U-shaped paper stack falls down and stacks with the lower U-shaped paper stack. At this time, the flipping component is located below the roller bed 2. When the groove wheel 39 rotates 360° again, the L-shaped paper stack does not flip, so that the upper U-shaped paper stack and the lower U-shaped paper stack are stacked in a staggered manner. The above movement is repeated to perform U-shaped staggered stacking, which improves the stability of the paper stack to a certain extent.

When the lifting... When the frame 41 rises, the lifting baffle 8 descends under the action of the fourth gear 83, and the L-shaped paper stack moves to below the lifting rod 85. At the same time, the push rod 90 moves laterally under the action of the reciprocating screw 88, pushing the L-shaped paper stack on one side to the other side to merge and form a U-shaped paper stack. Since the U-shaped frame 60 is located in the first through groove 33, the next set of L-shaped paper stacks cannot be flipped. When the groove wheel 39 rotates 720°, the U-shaped frame 60 continues to rotate 180° to reset. When the lifting rod 85 moves laterally to the outside of the roller bed 2, the U-shaped paper stack above the lifting rod 85 falls and stacks with the U-shaped paper stack below in a staggered manner. Repeat the above movements to perform a staggered stacking pattern. Once stacking is complete, pull the second baffle 21 to push the stacked paper stack out through the third through slot 36. This solves the problem that most stacking methods are divided into overlapping stacking, cross-row stacking, and staggered stacking. Among them, the staggered stacking pattern has higher stability, but it is more difficult to stack. Most existing stacking machines for corrugated cardboard box production require the use of robotic arms for staggered stacking. Since the corrugated cardboard box itself is relatively fragile, the robotic arm is prone to physical damage to the cardboard box during the clamping process, which increases production costs and reduces production efficiency to a certain extent.
