Automatic stacking device for cabinet body plates

Abstract

This invention relates to an automatic stacking device for cabinet panels, used for stacking cabinet panels stored in a storage compartment. Through a grid-like floor seam, the first traveling wheel travels in a groove while the second traveling wheel travels on the floor, forming a double-layer traveling structure with the driving wheel sinking and the driven wheel providing planar support. This effectively reduces the overall height of the device, making the horizontal conveying unit easier to store and significantly improving the utilization rate of stacking space. Simultaneously, the hinged linkage structure with the adjusting rod allows for the retraction and extension of the horizontal conveying unit, preventing it from occupying the passageway when not in operation, further improving space utilization efficiency. It achieves stable stopping and placing, fundamentally eliminating the "seesaw" effect without increasing the load. This achieves automated, high-precision stacking operations, effectively improving warehouse management efficiency and operational accuracy.

Description

Technical Field

[0001] This invention relates to the field of warehouse transportation, and more specifically to an automatic stacking device for cabinet panels. Background Technology

[0002] During the processing of cabinets, the required sheet metal components (such as cabinet doors, boxes, partitions, drawer panels, etc.) are usually retrieved from the warehouse stacking space. The stacking space is typically divided into multiple stacking compartments facing different directions. The stacking compartments are all rack structures that store the various sheet metal components required for processing the cabinets. At least one opening or gap must be left in the stacking space for transport trailers to enter and exit.

[0003] In the existing technology, the bottom plate of the stacking space is a whole plane. During the movement of the transport trailer, the horizontal conveying units such as the conveyor belt cannot be stored, resulting in a large space occupation. In the narrow storage space, usually only one transport trailer can enter and exit, and the efficiency of picking / storing sheet metal parts is very low. Secondly, when picking up / stores sheet metal parts, existing transport trailers experience a "seesaw" effect due to an unstable center of gravity, causing the vehicle to tilt. To solve this problem, existing technologies usually make the vehicle body larger or add counterweights to the bottom of the vehicle body. While this can solve the problem to some extent, it takes up more space, increases energy consumption, and when the horizontal conveying unit carries a large number of sheets, the "seesaw" effect will still occur, and the sheets may even slip off. Summary of the Invention

[0004] To address the technical challenges mentioned in the background section, and to improve the stability and operational flexibility of vehicle stacking without ballast, while also increasing the utilization rate of stacking space, the following solution is proposed: An automatic cabinet panel stacking device is disclosed for stacking cabinet panels stored in a stacking compartment. Stacking is achieved by a stacking cart that moves across the floor. The stacking operation includes the retrieval and storage of cabinet panels. The stacking cart includes a vehicle body, a first traveling wheel located at the center of the bottom of the vehicle body, and multiple second traveling wheels located at the bottom of the vehicle body. The floor has a grid-like floor seam, with upper seams forming slits between adjacent floor panels, and a recessed groove forming at the bottom of the floor. The first traveling wheel is the driving wheel, moving within the recessed groove; the second traveling wheels are the driven wheels, moving across the floor.

[0005] The floor seam is composed of multiple strips connected end to end on the same plane.

[0006] The driven wheel is a swivel wheel.

[0007] The first traveling wheel is connected to the traveling power unit via a telescopic rod. The traveling power unit can be a servo linkage or a hydraulic cylinder. The traveling power unit is electrically connected to the central control unit.

[0008] When the stacker truck needs to change direction, it stops at the intersection of the slots, and the first traveling wheel is limited at the intersection of the slots. The central control unit controls the stacker truck to achieve "in-situ reversal".

[0009] The slot serves as a preset path for the stacker truck to travel along, and can be recognized by the image recognition device of the stacker truck, enabling the stacker truck to travel in a straight line along the slot.

[0010] The stacking compartment includes multiple vertically spaced compartments, with adjacent compartments forming storage units. Cabinet panels of the same type are stored in the same storage unit. Each storage unit is equipped with a corresponding electronic tag on its exterior, which can be scanned and identified by stacker trucks.

[0011] The stacker vehicle also includes a lifting unit and a horizontal conveying unit connected to each other. The horizontal conveying unit includes columns and a top beam. Two columns are respectively set on both sides of the vehicle body, and the two adjacent columns are connected by the top beam. The horizontal conveying unit includes a conveyor belt, which conveys the plates to the top of the vehicle body for stacking. The lifting unit drives the horizontal conveying unit to move vertically.

[0012] The stacker truck uses image recognition to determine the inventory of cabinet panels in the storage unit in front and scans the electronic tags on the outside of each storage unit. When a target storage unit is identified, the truck moves toward the target storage unit. The central control unit inside the truck controls the lifting unit to operate according to the height signal fed back by storage unit "2503". The lifting unit drives the horizontal conveyor unit to a preset height position. At this time, according to the feedback distance signal, the first traveling wheel is driven to walk along the sinkhole until the preset distance position. The horizontal conveyor unit extends into the storage unit of the stacking compartment to retrieve the cabinet panels. The number of cabinet panels retrieved is set according to the actual processing needs.

[0013] The lifting unit also includes a lifting motor installed on the upper part of the column. The lifting motor is connected to the horizontal conveying unit through a transmission chain. A sliding groove is formed on the inner side of the column, and the horizontal conveying unit can move up and down along the sliding groove.

[0014] The horizontal conveying unit includes a support frame, which comprises a horizontal frame and a vertical frame connected perpendicularly to each other, and the front end of the horizontal frame is formed with a wedge-shaped tip.

[0015] A transmission control unit is installed inside the cross frame. One side of the transmission control unit is electrically connected to the central control unit. The other side of the transmission control unit drives the rotating shaft to rotate. There are multiple rotating shafts, which are arranged side by side on one side and / or both sides of the cross frame. Each rotating shaft is equipped with multiple rollers. The rollers abut against the inner surface of the conveyor belt, thereby supporting the conveyor belt.

[0016] One end of the vertical frame away from the tip is hinged to one side of the support column, and the other side of the support column is hinged to one side of the adjusting rod. The other side of the adjusting rod is hinged to the vertical frame. A first crossbar and a second crossbar are provided on the side of the support column facing the column. Bearings are provided at the ends of the first crossbar and the second crossbar. The bearings are located in sliding grooves and are connected to the transmission chain.

[0017] Compared with the prior art, the automatic stacking device for cabinet panels proposed in this invention application has the following advantages: 1) This application uses a grid-like floor seam on the floor to allow the first traveling wheel to travel in the sinkhole and the second traveling wheel to travel on the floor, forming a double-layer traveling structure with the driving wheel sinking and the driven wheel supporting the plane. This effectively reduces the overall height of the vehicle body, makes the horizontal conveying unit easier to store, and greatly improves the utilization rate of stacking space. At the same time, with the hinged linkage structure of the adjusting rod, the horizontal conveying unit can be retracted and extended, avoiding the occupation of the passage when not in operation, and further improving the space utilization efficiency. 2) This application uses the driving wheel and driven wheel to move in different positions and lock them in place during stacking operations. It can achieve stable stopping and placing regardless of how many plates are carried, thereby fundamentally eliminating the "seesaw" effect without increasing the load. 3) At the intersection of the slots, the first traveling wheel can limit the movement of the stacker truck to 90° in place, which significantly improves the flexibility and efficiency of the truck in moving between stacking compartments with different orientations. 4) It has achieved automated and high-precision stacking operations, which has effectively improved the efficiency of warehouse management and the accuracy of operations.

Detailed Implementation

[0019] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the innovative points and general methods of the present invention. The embodiments described are only used to explain the present invention and should not be regarded as a limitation on the scope of protection of the present invention.

[0020] In existing technologies, stacking spaces typically consist of three storage compartments facing different directions (e.g., in a floor plan, the three compartments are located to the east, west, and north). These compartments are rack-like structures that store various sheet metal components of the processing cabinets (e.g., cabinet doors, boxes, partitions, drawer panels, etc.). An opening is formed in another direction (e.g., to the south) for AGVs, forklifts, and other sheet metal transport trailers to enter and exit. However, the bottom of the stacking space is a single flat surface, preventing the horizontal conveyor units such as conveyor belts from being retracted during transport trailer movement, resulting in a large space occupation, even in a 10m x 10m storage space. Inside, only one transport trailer can usually enter and exit at a time, resulting in very low efficiency in picking up / storing sheet metal parts. Secondly, when picking up / storing sheet metal parts, the existing transport trailers become unstable due to the "seesaw" effect. To solve this problem, existing technologies usually make the vehicle body larger or add counterweights to the bottom of the vehicle body. Although this can solve the problem to some extent, it takes up more space, increases energy consumption, and when the horizontal conveying unit carries a large number of sheets (for example, picking up 20 sheets at a time), the "seesaw" effect will still occur, and the sheets may even slip off.

[0021] To address the aforementioned problems, this embodiment provides an automatic stacking device for cabinet panels, such as... Figures 1 to 5 As shown: An automatic stacking device for cabinet panels is used to stack cabinet panels 10 stored in a stacking compartment 1. The stacking is achieved by a stacking cart 4 that moves on the floor 2. The stacking operation includes taking and storing cabinet panels.

[0022] The stacker truck 4 includes a vehicle body 14, a first traveling wheel 15 is set at the center of the bottom of the vehicle body 14, and a second traveling wheel 16 is set at each of the four corners of the bottom of the vehicle body 14. The floor 2 is provided with grid-like floor seams 3. The floor 2 is T-shaped. The upper part of adjacent floor 2 forms a strip seam 17, and the lower part forms a groove 18. The floor seam 3 is formed by connecting multiple strip seams 17 on the same plane end to end.

[0023] The first traveling wheel 15 is the driving wheel, and the second traveling wheel 16 is the driven wheel, with the driven wheel being a swivel caster. The first traveling wheel 15 is connected to the traveling power unit via a telescopic rod. The traveling power unit can be a servo linkage or a hydraulic cylinder. The traveling power unit is electrically connected to the central control unit. When the central control unit sends a "retract" signal to the traveling power unit, the first traveling wheel 15 abuts against the inner wall of the settling tank 18. At this time, the stacker truck 4 is positioned on the floor 2. Regardless of which side the stacker truck is subjected to force from, the truck body can be stably parked without a "seesaw" effect. When the central control unit sends a "release" signal to the traveling power unit, the first traveling wheel 15 is no longer in contact with the inner wall of the settling tank 18. At this time, the stacker truck 4 can move normally. When the stacker truck 4 needs to change direction to perform stacking operations in another storage compartment, the stacker truck 4 stops at the corresponding slot intersection position. Due to the limiting effect of the first traveling wheel 15 at the slot intersection position, the central control unit controls the stacker truck 4 to achieve a 90° "in-situ reversal".

[0024] In addition, the slot can be used as a preset path, which can be recognized by the image recognition device of the stacker truck 4, so that the stacker truck 4 can travel in a straight line along the slot 17 without deviating.

[0025] The stacking compartment 1 includes multiple vertically spaced compartments 9. Adjacent compartments 9 enclose each other to form a storage unit. Cabinet panels 10 of the same type are stored in the same storage unit. Each storage unit is equipped with a corresponding electronic tag on the outside, which can be scanned and identified by the stacker truck 4.

[0026] The stacker truck 4 also includes a lifting unit 5 and a horizontal conveying unit 6 connected to each other. Specifically, the horizontal conveying unit 6 includes a column 12 and a top beam 11. Two columns 12 are respectively set on both sides of the vehicle body 14, and the two adjacent columns 12 are connected by the top beam 11. The horizontal conveying unit 6 includes a conveyor belt 13, which conveys the plates to the top of the vehicle body 14 for stacking. The lifting unit 5 drives the horizontal conveying unit 6 to move vertically.

[0027] The stacker truck 4 uses image recognition to determine the inventory of cabinet panels in the storage unit in front and scans the electronic tags on the outside of each storage unit. When a target storage unit is identified (e.g., storage unit "2503" on shelf 5f of storage compartment #2, containing 15 partitions), the truck body 14 moves toward the target storage unit. The central control unit inside the truck body 14 controls the lifting unit 5 to move according to the height signal fed back by storage unit "2503". The lifting unit 5 drives the horizontal conveying unit 6 to a preset height position. At this time, according to the feedback distance signal, the first traveling wheel 15 is driven to walk along the sink 18 until the preset distance position. The horizontal conveying unit 6 extends into the storage unit of the stacking compartment to retrieve the cabinet panels 10. The number of cabinet panels 10 retrieved is set according to the actual processing needs.

[0028] The top of the stacker truck 4 is also equipped with a transfer conveyor belt. When the stacker truck 4 completes the stacking operation of the cabinet panels, it moves towards the position of the transfer trolley 7 parked on the corridor 8 and transfers the stacked cabinet panels 10 to the transfer trolley 7 via the transfer conveyor belt. When the transfer trolley 7 senses a stable pressure signal, it sends a "transfer completed" signal to the stacker truck 4, and the stacker truck 4 proceeds to the next round of stacking operation.

[0029] The transfer cart uses an AGV (Automated Guided Vehicle).

[0030] The lifting unit 5 also includes a lifting motor 19 located on the upper part of the column 12. The lifting motor 19 is connected to the horizontal conveying unit 6 through a transmission chain. A sliding groove 20 is formed on the inner side of the column 12, and the horizontal conveying unit 6 can move up and down along the sliding groove 20.

[0031] The horizontal conveying unit 6 includes a support frame 21, which includes a horizontal frame 21-2 and a vertical frame 21-3 that are perpendicularly connected to each other. The front end of the horizontal frame 21-2 is formed with a wedge-shaped tip 21-1. The tip 21-1 is made of a material with a certain degree of elasticity to avoid damaging the cabinet panel 10 when picking it up. When the stacking device moves forward to the front of the stacking compartment 1, the tip 21-1 can reach into the lower part of the cabinet panel 10 to pick it up.

[0032] A transmission control unit is installed inside the cross frame 21-2. One side of the transmission control unit is electrically connected to the central control unit, and the other side of the transmission control unit drives the rotating shaft 22 to rotate. There are multiple rotating shafts 22, which are arranged side by side on one side and / or both sides of the cross frame 21-2. Each rotating shaft 22 is equipped with multiple rollers 28. The rollers 28 abut against the inner surface of the conveyor belt 13, thereby supporting the conveyor belt 13.

[0033] One end of the vertical frame 21-3 away from the tip 21-1 is hinged to one side of the support column 24, and the other side of the support column 24 is hinged to one side of the adjusting rod 23. The other side of the adjusting rod 23 is hinged to the vertical frame 21-3. A first horizontal bar 25 and a second horizontal bar 27 are provided on the side of the support column 24 facing the column 12. Bearings 26 are provided at the ends of the first horizontal bar 25 and the second horizontal bar 27. The bearings 26 are located in the sliding groove 20 and are connected to the transmission chain.

[0034] When the adjusting rod 23 extends, the horizontal conveying unit 6 rotates upward relative to the lifting unit 5, thereby retracting the horizontal conveying unit 6 and preventing it from occupying a position and affecting the stacking operation of other stacker trucks 4. When the adjusting rod 23 retracts, the horizontal conveying unit 6 rotates downward relative to the lifting unit 5, thereby extending the horizontal conveying unit 6.

[0035] Those skilled in the art should understand that the above embodiments are merely descriptions of the optimal implementation scheme of the present invention and are not limited to the above technical solutions. Other technical solutions formed by arbitrarily combining the above technical features or their equivalent features without departing from the basic concept of the present invention, such as technical solutions formed by replacing the above technical features with technical features with similar functions invented in the present invention, are also possible. The scope of protection of the present invention is determined by the technical solutions covered by the claims.
