Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing equipment technology, and in particular to a corrugated cardboard batch stacking device. Background Technology

[0002] Corrugated cardboard is a widely used type of packaging paperboard. Generally, after corrugated cardboard is made into continuous sheets, it is cut and crimped according to the required size to finally produce corrugated cardboard of a predetermined specification. After the corrugated cardboard is produced to the predetermined specification, it is stacked into stacks, and then the stacked corrugated cardboard is secured with straps, packaged, and transported.

[0003] Currently, corrugated cardboard is cut and crimped using a corrugated cardboard cutting and crimping device. After cutting and crimping, the corrugated cardboard is stacked through subsequent conveying and stacking processes. However, the conveying process requires manual intervention for batch processing. When the number of corrugated cardboard pieces conveyed to the stacking stage reaches a preset quantity, the conveyor is manually slowed down. Once the batch of corrugated cardboard is stacked and output, the speed is returned to the original speed. However, this manual intervention method for batch processing of corrugated cardboard is inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a corrugated cardboard batch stacking device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A corrugated cardboard batch stacking device is located behind a corrugated cardboard cutting and pressing device. It includes a seam cleaning conveyor, a deceleration conveyor, a counting conveyor, and a stacking output device arranged sequentially from front to back. The seam cleaning conveyor removes the seams on the corrugated cardboard and conveys the cleaned corrugated cardboard to the deceleration conveyor. The deceleration conveyor conveys the corrugated cardboard to the counting conveyor by overlapping the ends of the received corrugated cardboard into a line. The counting conveyor conveys the received corrugated cardboard to the stacking output device at a dual speed with a preset number of points and batches. The stacking output device stacks each batch of corrugated cardboard in sequence and outputs the stacked corrugated cardboard to the outside.

[0007] The counting and conveying device includes a connecting base and a counting and conveying frame fixed on the connecting base. The counting and conveying frame forms a counting and conveying surface for conveying corrugated cardboard, a dual-speed conveying structure for driving the corrugated cardboard along the counting and conveying surface, and several photoelectric sensors at the front end of the counting and conveying surface for counting the corrugated cardboard. When the corrugated cardboard falls into the front end of the counting and conveying surface, the photoelectric sensors count the cardboard. Before the preset quantity of the batch is reached, the dual-speed conveying structure conveys the corrugated cardboard at a constant speed to the stacking output device. When the preset quantity of the batch is reached, before the next corrugated cardboard falls into the counting and conveying surface, the dual-speed conveying structure speeds up the conveying of the corrugated cardboard to the stacking output device.

[0008] The stacking output device includes a main frame, a lifting output seat, a forward / backward baffle module, a reciprocating clamping arm module, a reciprocating stop plate module, and a forward / backward fork module. Inside the main frame, below the output end of the counting conveyor, a receiving station and a discharging station are sequentially formed. The receiving station has a receiving area at one end adjacent to the counting conveyor. The main frame contains a lifting drive structure, and the lifting output seat is mounted on the lifting drive structure, allowing it to reciprocate between the receiving and discharging stations within the main frame. The forward / backward baffle module is positioned at the top rear end of the main frame relative to the rear end of the receiving area. The reciprocating clamping arm module is positioned at the top front end of the main frame relative to both sides of the receiving area. The reciprocating stop plate module is positioned at the front end of the main frame adjacent to the front end of the receiving area. One end of the near-counting conveyor; the forward and backward fork module is set at the outer end of the main frame adjacent to the counting conveyor, which can move forward and backward relative to the receiving area. During the process of the counting conveyor feeding a batch of corrugated cardboard into the main frame, the forward and backward baffle module moves to the rear end of the receiving area, and the lifting output seat rises to the receiving station to support the corrugated cardboard falling into the receiving area. As the corrugated cardboard is fed in, the reciprocating clamping arm module pushes back and forth on both sides of the receiving area, and the reciprocating abutment module pushes back and forth on the front end of the receiving area. The lifting output seat gradually moves down from the receiving station to the discharge station. After all the corrugated cardboard in this batch has been fed in, the lifting output seat moves down to the discharge station and outputs the corrugated cardboard to the outside. The forward and backward fork module enters the receiving area to support the next batch of corrugated cardboard. After the corrugated cardboard is output to the outside, the lifting output seat rises back to the receiving station.

[0009] As a further technical solution of the present invention: the seam cleaning and conveying device includes a guide rail base and a seam cleaning main unit that can be moved back and forth on the guide rail base. The seam cleaning main unit includes a lower seam cleaning seat and an upper seam cleaning seat that can be adjusted up and down relative to the lower seam cleaning seat and is arranged above the lower seam cleaning seat. A seam cleaning conveying channel for conveying corrugated cardboard is formed between the lower seam cleaning seat and the upper seam cleaning seat. The seam cleaning conveying channel sequentially forms a first air blowing position, a rotating top position and a second air blowing position. Both the lower seam cleaning seat and the upper seam cleaning seat are provided with a plurality of conveying units that convey corrugated cardboard to a deceleration conveying device and a shaft rotation drive structure for driving the plurality of conveying units at their rear ends. The lower seam cleaning seat is provided with a rotating abutment structure at the position corresponding to the rotating top position.

The inlet end of the inclined conveying surface is located below the end of the seam clearing conveyor, and the outlet end of the inclined conveying surface is located above the counting conveying device.

[0011] As a further technical solution of the present invention: the seam cleaning seat is provided with an air supply structure on its top for supplying air to the two sets of air outlet structures; the swing conveyor frame includes a lifting bracket that can be lifted and lowered on the fixed base and a conveying bracket that can be swinged and hinged to the top of the lifting bracket, the conveying bracket forming an inclined conveying section for conveying from low to high, and the inclined conveying section is provided with a plurality of first suction strip seats at intervals; the counting conveyor frame includes a plurality of second suction strip seats that are provided at intervals on the top of the connecting base; the seam cleaning conveying device, the deceleration conveying device, and the counting conveying device share a common air supply system, the air outlet of the air supply system is connected to the air supply structure, and the air suction end of the air supply system is connected to the first suction strip seat and the second suction strip seat respectively.

[0012] As a further technical solution of the present invention: the forward and backward fork module includes a traction frame fixed below the counting conveyor, two traction shafts rotatably disposed at both ends of the traction frame, a traction drive unit disposed on one side of the traction frame to drive the traction shaft to rotate, a plurality of traction wheels spaced apart on each traction shaft, a traction belt sleeved on the traction wheels corresponding to the two traction shafts, and a plurality of forks spaced apart on the traction frame that can move forward and backward along the traction frame. Each fork has an electrically controlled clamp at the bottom corresponding to a traction belt, which allows the traction drive unit to drive the traction shaft to rotate, so that the plurality of traction belts operate synchronously. The fork that needs to be inserted into the receiving area is clamped by the electrically controlled clamp. After it is inserted into the receiving area with the operation of the traction belt, the electrically controlled clamp releases the traction belt.

[0013] As a further technical solution of the present invention: the reciprocating abutment module includes an abutment body that can be reciprocally and movably disposed at the front end of the receiving area, an eccentric wheel transmission structure fixedly disposed at one end of the connecting base near the main frame, and a connecting frame connecting the abutment body and the eccentric wheel transmission structure, so that the eccentric wheel transmission structure and the connecting frame cooperate to drive the abutment body to reciprocate relative to the front end of the receiving area.

[0014] As a further technical solution of the present invention: the main body of the backing plate is provided with several openings and several air holes at intervals. Each opening is provided with a fork rod that is inserted into the receiving area. Each air hole is provided with an air blowing unit that blows air toward the receiving area to improve the material dropping efficiency of corrugated cardboard.

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of the present invention.

[0030] Please see Figure 1 , Figure 2 and Figure 3 A corrugated cardboard batch stacking device is located behind a corrugated cardboard cutting and pressing device. It includes a seam cleaning conveyor 10, a deceleration conveyor 20, a counting conveyor 30, and a stacking output device 40 arranged sequentially from front to back. The seam cleaning conveyor 10 removes the seams on the corrugated cardboard and conveys the seam-cleaned corrugated cardboard to the deceleration conveyor 20. The deceleration conveyor 20 conveys the corrugated cardboard to the counting conveyor 30 by overlapping the ends of the received corrugated cardboard into a line. The counting conveyor 30 conveys the received corrugated cardboard to the stacking output device 40 at a preset number of points and in batches at a dual speed. The stacking output device 40 stacks each batch of corrugated cardboard in sequence and outputs the stacked corrugated cardboard to the outside.

[0031] See also Figure 4The anti-corrosion conveying device 10 includes a guide rail base 11 and an anti-corrosion main unit 12 that can move back and forth on the guide rail base 11. The anti-corrosion main unit 12 includes an anti-corrosion lower seat 121 and an anti-corrosion upper seat 122 that can be adjusted up and down relative to the anti-corrosion lower seat 121 and is arranged above the anti-corrosion lower seat 121. An anti-corrosion conveying channel 123 for conveying corrugated cardboard is formed between the anti-corrosion lower seat 121 and the anti-corrosion upper seat 122. The anti-corrosion conveying channel 123 sequentially forms a first air blowing position 1231, a rotating top position 1232 and a second air blowing position 1233. The anti-corrosion lower seat 121 and the anti-corrosion upper seat 122 are each provided with a plurality of conveying units 13 that convey corrugated cardboard to the deceleration conveying device 20, and a shaft at their rear end for driving the plurality of conveying units 13. The rotating drive structure 14; the lower cleaning seat 121 is provided with a rotating abutment structure 15 at the position corresponding to the rotating top position 1232, and the upper cleaning seat 122 is provided with an air outlet structure 16 at the positions corresponding to the first air blowing position 1231 and the second air blowing position 1233. When the conveying unit 13 of the lower cleaning seat 121 and the upper cleaning seat 122 drives the corrugated cardboard from the cleaning conveyor 123 to the deceleration conveyor 20, the air outlet structure 16 of the first air blowing position 1231 blows air onto the seam strips remaining in the cut of the corrugated cardboard, causing the seam strips to loosen. The rotating abutment structure 15 of the rotating top position 1232 abuts against the corrugated cardboard at a predetermined frequency as it rotates, causing the seam strips to fall off. The air outlet structure 16 of the second air blowing position 1233 blows the seam strips off the corrugated cardboard, thus achieving seam cleaning.

[0032] See also Figure 5 The deceleration conveying device 20 includes a fixed base 21 and a swing conveying frame 22 that can be lifted and swung on the fixed base 21. The swing conveying frame 22 forms an inclined conveying surface 201 for conveying corrugated cardboard from low to high, an inclined conveying structure 202 for driving the corrugated cardboard along the inclined conveying surface 201, and a pressing structure 23 for pressing and orienting the corrugated cardboard on the inclined conveying surface 201. The inlet end of the inclined conveying surface 201 is located below the end of the seam clearing conveyor 123, and the outlet end of the inclined conveying surface 201 is located above the counting conveying device 30. Under the height difference, both the inlet and outlet are decelerated, and the corrugated cardboard can be overlapped end to end. Through the orientation of the pressing structure 23, it falls into the counting conveying device 30 in a straight line.

[0033] See also Figure 6The counting and conveying device 30 includes a connecting base 31 and a counting and conveying frame 32 fixed on the connecting base 31. The counting and conveying frame 32 forms a counting and conveying surface 301 for conveying corrugated cardboard, a dual-speed conveying structure 302 for driving the corrugated cardboard along the counting and conveying surface 301, and a plurality of photoelectric sensors 33 at the front end of the counting and conveying surface 301 to count the corrugated cardboard. When the corrugated cardboard falls into the front end of the counting and conveying surface 301, the photoelectric sensors 33 count the cardboard. Before the preset quantity of the batch is reached, the dual-speed conveying structure 302 conveys the corrugated cardboard at a uniform speed to the stacking output device 40. When the preset quantity of the batch is reached, before the next corrugated cardboard falls into the counting and conveying surface 301, the dual-speed conveying structure 302 speeds up the conveying of the corrugated cardboard to the stacking output device 40.

[0034] The stacking output device 40 includes a main frame base 41, a lifting output base 42, an inward and outward baffle module 43, a reciprocating clamping arm module 44, a reciprocating stop plate module 45, and an inward and outward partition fork module 46. Inside the main frame base 41, below the output end of the counting conveyor 30, a receiving station 411 and a discharging station 412 are sequentially formed. The receiving station 411 has a receiving area 413 at one end adjacent to the counting conveyor 30. The main frame base 41 is equipped with a lifting drive structure 401. The ejector seat 42 is mounted on the lifting drive structure 401, allowing it to reciprocate between the receiving station 411 and the ejector station 412 within the main frame 41. The forward and backward baffle module 43 is positioned at the top rear end of the main frame 41, reciprocating relative to the rear end of the receiving area 413. The reciprocating clamping arm module 44 is positioned at the top front end of the main frame 41, reciprocating relative to both sides of the receiving area 413. The reciprocating abutment module 45 is positioned at the front end of the main frame 41, reciprocating relative to the front end of the receiving area 413. The frame base 41 is located near one end of the counting conveyor 30; the forward and backward fork module 46 is positioned relative to the receiving area 413 and is located outside one end of the main frame base 41 near the counting conveyor 30. During the process of the counting conveyor 30 feeding a batch of corrugated cardboard into the main frame base 41, the forward and backward baffle module 43 moves to the rear end of the receiving area 413, and the lifting output seat 42 rises to the receiving station 411 to support the corrugated cardboard falling into the receiving area 413. As the corrugated cardboard is fed in, the reciprocating clamping arm module... The reciprocating push plate module 45 pushes against the front end of the receiving area 413 on both sides of the receiving area 413, and the lifting output seat 42 gradually moves down from the receiving station 411 to the discharge station 412. After all the corrugated cardboard in this batch is input, the lifting output seat 42 moves down to the discharge station 412 and outputs the corrugated cardboard. Meanwhile, the forward and backward fork module 46 enters the receiving area 413 to support the next batch of corrugated cardboard. After the corrugated cardboard is output, the lifting output seat 42 rises back to the receiving station 411.

Each connecting post 101 is provided with an adjustment guide rail 1011 on which the conveying unit 13 is slidably mounted. Each conveying unit 13 is provided with an electrically controlled gripper 103 corresponding to the transmission belt structure 102. The electrically controlled gripper 103 clamps the belt of the transmission belt structure 102, and the transmission belt structure 102 drives the conveying unit 13 to slide along the adjustment guide rail 1011, thereby adjusting the spacing between the conveying units 13.

[0036] Furthermore, in this embodiment, the conveying unit 13 includes a conveying seat 131, a plurality of transmission wheels 132, and a conveying belt 133. The conveying seat 131 forms a base section 1311, and two seat arm sections 1312 extend from both ends of the base section 1311 toward the seam clearing conveyor 123, and an installation space 134 is reserved between the two seat arm sections 1312 for the installation of a rotating abutment structure 15 or an air outlet structure 16. The base section 1311 extends at its rear end to form a lower arm section 1313 that is vertically opposite to the seat arm section 1312 at that end. A through-hole 135 is provided between the base section 1311 and the opposite arm section 1312 for mounting the shaft rotation drive structure 14. Several transmission wheels 132 are spaced apart at both ends of the base section 1311, the top ends of the arm section 1312, and the lower arm section 1313. A conveyor belt 133 is fitted onto the transmission wheels 132 and the shaft rotation drive structure 14. Rotation of the shaft rotation drive structure 14 drives the conveyor belt 133 to rotate on the transmission wheels 132. The conveyor belt 133 abuts against the corrugated cardboard in the seam clearing conveyor 123, thereby conveying the corrugated cardboard along the seam clearing conveyor 123. The base section 1311 has a slider at each end of its bottom or top that matches the adjusting guide rail 1011, and the base section 1311 has an electrically controlled gripper 103 in its bottom or top middle section.

The rotating drive unit 152 drives the rectangular rotating shaft 151 to rotate, and the edge of the rectangular rotating shaft 151 abuts against the conveying ring belt 133 of the conveying unit 13 of the seam cleaning seat 121 in sequence as it rotates, thereby abutting the corrugated cardboard at a predetermined frequency.

[0038] Furthermore, in this embodiment, the lower cleaning seat 121 is provided with a plurality of lifting drive cylinders 104 spaced apart on the bottom of its outer wall. Each lifting drive cylinder 104 has a lifting guide rail 1041 erected on its telescopic rod. The top of the lifting guide rail 1041 is fixed to the outer wall of the upper cleaning seat 122. The lower cleaning seat 121 is provided with a positioning seat 105 on the top of its outer wall corresponding to each lifting drive cylinder 104, through which the lifting guide rail 1041 can slide. The telescopic rod of the lifting drive cylinder 104 extends and retracts, causing the upper cleaning seat 122 to rise and fall relative to the lower cleaning seat 121, thereby adjusting the height of the cleaning conveyor 123.

[0039] Furthermore, in this embodiment, the upper seat 122 for cleaning seams is provided with an air supply structure 106 on its top for supplying air to the two sets of air outlet structures 16. The air supply structure 106 is provided with two sets of push-pull units 107 for adjusting the opening and closing amplitude of the air outlets that supply air to the two sets of air outlet structures 16 respectively.

[0040] Furthermore, in this embodiment, the guide rail base 11 is provided with an adjustment drive cylinder 111 for driving the cleaning host 12 to slide along it. When the output end of the corrugated cardboard cutting and pressing device needs to be repaired, the swing conveyor frame 22 on the deceleration conveyor 20 swings, and the adjustment drive cylinder 111 drives the cleaning host 12 to move towards the deceleration conveyor 20, thereby freeing up maintenance space between the corrugated cardboard cutting and pressing device and the cleaning conveyor 10.

[0041] Furthermore, in conjunction with reference Figure 9 , Figure 10 In this embodiment, the fixed base 21 has two opposing support seats 211 and a connecting rod 212 connecting the two support seats 211.

[0049] Furthermore, in this embodiment, the advance and retreat baffle module 43 includes a baffle seat 431 that can be slidably disposed at the top rear end of the main frame seat 41, a baffle body 432 connected below the baffle seat 431, and a baffle driving structure disposed on the baffle seat 431 for driving the baffle seat 431 to slide advance and retreat along the top of the main frame seat 41. The baffle driving structure operates to drive the baffle body 432 to move to the rear end of the receiving area 413 to block the corrugated cardboard.

[0050] Understandably, the method of using the corrugated cardboard batch stacking device of the present invention includes the following steps: First, the corrugated cardboard cutting and pressing device conveys the corrugated cardboard to the seam cleaning conveying device 10. In the seam cleaning conveying device 10, the conveying units 13 of the lower seam cleaning seat 121 and the upper seam cleaning seat 122 drive the corrugated cardboard from the seam cleaning conveying channel 123 to the deceleration conveying device 20. The air outlet structure 16 of the first air blowing position 1231 blows air onto the seam strips remaining in the cut seams of the corrugated cardboard, loosening the seam strips. The rotating abutting structure 15 of the rotating top position 1232 abuts against the corrugated cardboard at a predetermined frequency as it rotates, causing the seam strips to fall off. The air outlet structure 16 of the second air blowing position 1233 blows the seam strip off the corrugated cardboard, achieving seam cleaning; in the second step, the deceleration conveyor 20 receives the corrugated cardboard output from the seam cleaning conveyor 10. Due to the height difference between the corrugated cardboard and the seam cleaning conveyor 10 and the counting conveyor 30, both its infeed and outfeed are decelerated, and the corrugated cardboard it receives can overlap end to end. Through the orientation of the pressing structure 23, it falls into the counting conveyor 30 in a straight line; in the third step, the counting conveyor 30 receives the corrugated cardboard output from the deceleration conveyor 20, and when the corrugated cardboard falls into the front end of the counting conveyor surface 301, the photoelectric sensor 33 marks the seam. In the first step, before the preset quantity of the batch is reached, the dual-speed conveyor structure 302 conveys the corrugated cardboard at a constant speed to the stacking output device 40. When the preset quantity is reached, before the next corrugated cardboard falls onto the counting conveyor surface 301, the dual-speed conveyor structure 302 accelerates the conveying of the corrugated cardboard to the stacking output device 40, achieving batching. In the fourth step, within the stacking output device 40, as the counting conveyor 30 inputs a batch of corrugated cardboard into the main frame seat 41, the forward / backward baffle module 43 moves to the rear end of the receiving area 413, and the lifting output seat 42 rises to the receiving station 411, supporting the corrugated cardboard falling into the receiving area 413. As corrugated cardboard is fed in, the reciprocating clamping arm module 44 pushes against both sides of the receiving area 413, and the reciprocating abutment module 45 pushes against the front end of the receiving area 413. The lifting output seat 42 gradually moves down from the receiving station 411 to the discharge station 412. After all the corrugated cardboard in this batch has been fed in, the lifting output seat 42 moves down to the discharge station 412 and outputs the corrugated cardboard. Meanwhile, the forward and backward fork module 46 enters the receiving area 413 to support the next batch of corrugated cardboard. After the output is completed, the lifting output seat 42 rises back to the receiving station 411, and the forward and backward fork module 46 retracts and exits from the receiving area 413. In this way, the corrugated cardboard is cleaned and stacked in batches, effectively preventing seam strips from getting mixed into the stack of corrugated cardboard, preventing deformation of the corrugated cardboard, and effectively improving the production quality of corrugated cardboard.

[0051] In summary, the corrugated cardboard batch stacking device of the present invention effectively realizes the cleaning and batch stacking of corrugated cardboard through the cooperation of the seam cleaning conveyor 10, the deceleration conveyor 20, the counting conveyor 30 and the stacking output device 40, so that the batch stacking of corrugated cardboard does not require manual intervention and improves the batch stacking efficiency of corrugated cardboard.

[0052] Any combination of various embodiments of the present invention, provided it does not violate the inventive concept of the present invention, shall be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, any simple modifications to the technical solution and any combination of different embodiments that do not violate the inventive concept of the present invention shall be within the protection scope of the present invention.
