Description

Technical Field

[0001] The invention belongs to the technical field of stacking elevators, in particular to a wooden board stacking elevator. Background Art

[0002] In the production process of wooden furniture, it is often necessary to transport and stack the wooden boards so that the wood can be transported to the next process for further processing. Among them, stacking means transporting the template located at a lower place to the stacking place at a higher place by loading and unloading, so as to realize the regularity and transportation preparation of the wooden boards. In the prior art, the stacking of wooden boards is mainly realized by vacuum suction cups and clamping mechanisms on both sides to fix and unload the wooden boards. However, the vacuum suction cups may fail due to the failure of the suction cups caused by the cylinder failure, which may cause the wooden boards to lose support. The reliability of the heavy wooden boards is not high enough. The use of the clamping mechanisms on both sides will bring another problem: a large clamping force is required to lift the heavy wooden boards. Therefore, in order to improve the stability, an inclined hook structure is generally provided to support the wooden boards from the bottom. However, the multiple layers of wooden boards stacked on the ground are tightly attached to each other, which brings troubles to the clamping and fixing of the lifting machine. If the wooden boards are forcibly inserted into the abutment between the two layers of wooden boards, the rigid pressure generated will damage the wooden boards. Therefore, it is urgent to design a wooden board stacking lifting machine that can significantly improve the above defects. Summary of the invention

[0003] The object of the present invention is to provide a wood board stacking and lifting machine to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wooden board stacking elevator, comprising a support plate, two groups of clamping blocks are installed at the bottom of the support plate, wood is clamped and installed between the two groups of clamping blocks, a placement cavity is opened on the inner side of the clamping block, a motor is installed on the front of the clamping block, the output shaft of the motor is fixedly installed with a gear 1 located in the inner cavity of the placement cavity, and a plurality of fixed cylinders 2 are fixedly installed on the oblique side of the inner wall of the placement cavity, a spring 2 and a telescopic column 2 are movably sleeved inside the fixed cylinder 2, a mounting frame is fixedly installed on one end of the telescopic column 2, a rotating shaft is rotatably installed inside the mounting frame, a roller is fixedly installed on the outer surface of the rotating shaft, a buffer sleeve is fixedly sleeved on the outer surface of the roller, a gear 3 located on the outer side of the mounting frame is fixedly installed on both ends of the rotating shaft, and a connecting rod located on the outer side of the gear 3 is movably sleeved, a gear 2 is rotatably installed on the inner side of the connecting rod, the gear 2 is meshed with the gear 3 and the gear 1 respectively, and a plurality of supporting components staggered with the fixed cylinder 2 are fixedly installed on the bottom of the oblique side of the inner wall of the placement cavity.

[0005] As a preferred solution of the present invention, the support assembly includes a fixed cylinder 1, which is horizontally distributed in the placement cavity, and the internal movably sleeve of the fixed cylinder 1 is provided with a telescopic column 1 and a spring 1, and the telescopic column 1 is elastically supported in the fixed cylinder 1 by the spring 1, and one end of the telescopic column 1 is fixedly connected to a support block, and the bottom of the support block is provided with an inclined surface, and the top of the support block is designed to be straight and abuts against the bottom of the wood.

[0006] As a preferred solution of the present invention, the two groups of clamping blocks are symmetrically distributed, the left and right sides of the wood are respectively in contact with the opposite surfaces of the two groups of clamping blocks, and the supporting assembly is located below the drum.

[0007] As a preferred solution of the present invention, the axis of the second fixing cylinder is inclined, and the upper surface of the wood is inclined at an angle of 30°, and the outer surfaces of the roller and the buffer sleeve are in contact with both sides of the wood.

[0008] As a preferred solution of the present invention, the buffer sleeve is made of hard rubber and is fixed to the middle part of the outer surface of the drum by gluing.

[0009] As a preferred solution of the present invention, the second spring is compressed and arranged at the bottom of the inner wall of the second fixed cylinder, and the second telescopic column is elastically supported on the inner wall of the second fixed cylinder through the second spring.

[0010] As a preferred solution of the present invention, gear 2 located in the placement cavity on one side is arranged into two groups which are symmetrical front and back and are connected by a fixed column. Gear 2 can rotate in a circle around the axis of gear 3 through a connecting rod and always keep in mesh with the outer surface of gear 1.

[0011] As a preferred solution of the present invention, the vertical part diameter lines of the roller and the rotating shaft are always located on one side of the inner cavity of the placement cavity, and the tip part of the top of the support block is designed in an arc transition.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. This elevator has been redesigned and adopts a gentler way to achieve the clamping function of the wood. It is equipped with a fixed cylinder 2 installed on the inclined side of the inner wall of the placement cavity, and the telescopic column 2, the mounting frame and the roller are elastically installed through the spring 2. When the telescopic column 2 is tilted 30° as a whole, the wood is used to enter between the two groups of clamping blocks and squeeze the roller, driving the mounting frame and the telescopic column 2 to move the compressed spring 2 to generate a rebound force. The two groups of rollers, under the inclined support of the fixed cylinder 2 and the telescopic column 2, generate a vertical upward thrust on the wood and a pressure perpendicular to the side of the wood, generating friction between the roller, the buffer sleeve and the side of the wood, and then the motor drives the gear 1, the gear 2 and the gear 3 to drive the roller and the buffer sleeve to rotate as a whole, and lift the wood upward to the moving distance, and then support the wood through the support assembly. This process utilizes the friction of the roller and the buffer sleeve on the wood, which greatly reduces the rigid damage to the wood during the stacking process.

[0014] 2. The device also installs a support assembly specially used for supporting wood under the roller and the mounting frame. The support assembly consists of a fixed cylinder, a telescopic column, a spring and a support block, wherein the top of the support block is designed to be flat, which is mainly used to provide bottom support for the wood that is rotated and lifted upward by the roller and the buffer sleeve. The support block uses the inclined surface design at its bottom. When installing the wood, the lateral force generated by the downward movement and the abutment against the two sides of the wood is used to push the support block toward the inside of the fixed cylinder, and compress the spring to generate a reset pressure. When unloading the wood, the inclined surface at the bottom of the support block contacts the wood at the stacking position by moving downward, or the limiting component contacts and re-enters the placement cavity, until the wood driven by the elevator is aligned with the wood at the stacking position and stacked neatly, so that the support block lacks a gap to move outward, and the unloading operation is automatically completed. The whole process is accurate, reliable and efficient.

[0015] 3. This device also increases the thrust for flexible clamping of the wood by tilting the axis of the second fixed cylinder. When the wood enters between the left and right groups of rollers, it contacts the rollers and the buffer sleeve to generate upward friction, and the telescopic column 2 generates an upward rebound force along the axis of the telescopic column 2 by compressing the second spring. The upward vertical component of this force can directly act on both sides of the wood, thereby improving the reliability of the roller and the buffer sleeve driving the wood to move upward through rotation.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 8As shown, an embodiment of the present invention provides a wood board stacking elevator, including a support plate 1, two groups of clamping blocks 2 are installed at the bottom of the support plate 1, wood 3 is clamped and installed between the two groups of clamping blocks 2, a placement cavity 14 is opened on the inner side of the clamping block 2, a motor 5 is installed on the front of the clamping block 2, the output shaft of the motor 5 is fixedly installed with a gear 6 located in the inner cavity of the placement cavity 14, a plurality of groups of fixed cylinders 8 are fixedly installed on the oblique side of the inner wall of the placement cavity 14, a spring 9 and a telescopic column 10 are movably sleeved inside the fixed cylinder 8, and one end of the telescopic column 10 is fixedly installed with a A mounting frame 11 is provided, wherein a rotating shaft 17 is rotatably installed inside the mounting frame 11, a roller 12 is fixedly installed on the outer surface of the rotating shaft 17, a buffer sleeve 13 is fixedly sleeved on the outer surface of the roller 12, a gear 3 16 located outside the mounting frame 11 is fixedly installed at both ends of the rotating shaft 17, and a connecting rod 15 located outside the gear 3 16 is movably sleeved, a gear 2 7 is rotatably installed inside the connecting rod 15, and the gear 2 7 is meshed with the gear 3 16 and the gear 1 6 respectively, and a plurality of supporting components 4 staggered with the fixed cylinder 2 8 are fixedly installed at the bottom of the oblique side of the inner wall of the placement cavity 14;

[0027] The present hoist has been redesigned to achieve the clamping function of the wood 3 in a gentler way. The fixed cylinder 28 is installed on the inclined side of the inner wall of the placement cavity 14, and the telescopic column 210, the mounting frame 11 and the roller 12 are elastically installed through the spring 29. When the telescopic column 210 is tilted 30° as a whole, the wood 3 is used to enter between the two groups of clamping blocks 2 and squeeze the roller 12, driving the mounting frame 11 and the telescopic column 210 to move and compress the spring 29 to generate a rebound force, and the two groups of rollers 12 are between the fixed cylinder 28 and the telescopic column 210. Under the inclined support of 10, the vertical upward thrust and the pressure perpendicular to the side of the wood 3 are generated, generating friction between the roller 12, the buffer sleeve 13 and the side of the wood 3, and then the motor 5 drives the gear 1 6, the gear 2 7 and the gear 3 16 to drive the roller 12 and the buffer sleeve 13 to rotate as a whole, and lift the wood 3 upward to the moving distance, and then support the wood 3 through the support assembly 4. This process utilizes the friction of the roller 12 and the buffer sleeve 13 on the wood 3, which greatly reduces the rigid damage to the wood 3 during the stacking process.

[0028] The support assembly 4 includes a fixed cylinder 41, which is horizontally distributed in the placement cavity 14. A telescopic column 42 and a spring 43 are movably sleeved inside the fixed cylinder 41. The telescopic column 42 is elastically supported in the fixed cylinder 41 by the spring 43. One end of the telescopic column 42 is fixedly connected to a support block 44. The bottom of the support block 44 is provided with an inclined surface. The top of the support block 44 is designed to be straight and abuts against the bottom of the wood 3.

[0029] The device also has a support assembly 4 specially used for supporting the wood 3 installed below the roller 12 and the mounting frame 11. The support assembly 4 is composed of a fixed cylinder 41, a telescopic column 42, a spring 43 and a support block 44, wherein the top of the support block 44 is designed to be flat, which is mainly used to provide bottom support for the wood 3 that is rotated and lifted upward by the roller 12 and the buffer sleeve 13. The support block 44 uses the inclined surface design at its bottom. When installing the wood 3, the lateral force generated by the downward movement and the abutment against the two sides of the wood 3 is used to push the support block 44 toward the inside of the fixed cylinder 41, and compress the spring 43 to generate a reset pressure. When unloading the wood 3, the inclined surface at the bottom of the support block 44 contacts the wood 3 at the stacking position by moving downward, or the limiting component contacts and re-enters the placement cavity 14, until the wood 3 driven by the elevator is aligned with the wood 3 at the stacking position and stacked neatly, so that the support block 44 lacks a gap for moving outward, and the unloading operation is automatically completed. The whole process is accurate, reliable and efficient.

[0030] The two groups of clamping blocks 2 are symmetrically distributed, the left and right sides of the wood 3 are respectively in contact with the opposite surfaces of the two groups of clamping blocks 2, and the support assembly 4 is located below the roller 12;

[0031] The two groups of clamping blocks 2 are symmetrically distributed on the left and right sides of the wood 3. The wood 3 is rotated by the roller 12 and the buffer sleeve 13 and lifted upward by the friction between the two. This design brings an advantage that both sides of the wood 3 are simultaneously subjected to the friction of the same direction and magnitude, and the force is balanced. There will be no damage to the corners caused by rigid clamping, which greatly maintains the integrity of the wood 3. The support component 4 is located below the roller 12. When the wood 3 is lifted upward by the roller 12 and the gap between it and the adjacent wood 3 on the lower side is exposed, the support component 4 can enter under the wood 3 and provide reliable support for the wood 3.

[0032] The axis of the fixed cylinder 8 is inclined and the upper surface of the wood 3 is inclined at an angle of 30°. The outer surfaces of the roller 12 and the buffer sleeve 13 are in contact with both sides of the wood 3.

[0033] The device also increases the thrust for flexibly clamping the wood 3 by tilting the axis of the fixed cylinder 2 8. When the wood 3 enters between the left and right groups of rollers 12, it contacts the rollers 12 and the buffer sleeves 13 to generate an upward friction force, and the telescopic column 2 10 generates a rebound force tilted upward along the axis of the telescopic column 2 10 through the compression spring 2 9. The upward vertical component of the force can directly act on both sides of the wood 3, thereby improving the reliability of the rollers 12 and the buffer sleeves 13 driving the wood 3 to move upward by rotating.

[0034] The buffer sleeve 13 is made of hard rubber and is fixed to the middle of the outer surface of the roller 12 by gluing;

[0035] The buffer sleeve 13 is responsible for generating deformation and friction after being squeezed by the wood 3 and the roller 12. The auxiliary roller 12 drives the buffer sleeve 13 to rotate and pushes the wood 3 upward. At the same time, the buffer sleeve 13 made of flexible material can also buffer and protect the side of the wood 3 to prevent the wood 3 from being damaged during the clamping process.

[0036] The second spring 9 is compressed and arranged at the bottom of the inner wall of the second fixed cylinder 8, and the second telescopic column 10 is elastically supported on the inner wall of the second fixed cylinder 8 by the second spring 9;

[0037] The spring 2 9 is compressed and generates a rebound force inclined upward along the axis of the telescopic column 2 10, which then directly acts on the side of the wood 3 through the roller 12 and the buffer sleeve 13 and generates friction. When the roller 12 and the buffer sleeve 13 rotate, the wood 3 can be smoothly pushed upward to achieve lifting and giving way before clamping.

[0038] Among them, the gear 2 7 located in the inner cavity of the placement cavity 14 on one side is set as two groups symmetrical in front and back, and is connected by a fixed column. The gear 2 7 can rotate around the axis of the gear 3 16 through the connecting rod 15 and always keep meshing with the outer surface of the gear 1 6;

[0039] Gear 2 7 is responsible for transmitting power to Gear 1 6 and Gear 3 16. Since the roller 12 and the buffer sleeve 13 often move for clamping and force storage, a connecting rod 15 is provided to fix the axial distance between Gear 2 7 and Gear 3 16, and through the rotation of Gear 2 7, it can mesh with Gear 1 6 and Gear 3 16 at the same time to realize the dynamic transmission function.

[0040] The vertical diameters of the roller 12 and the rotating shaft 17 are always located on one side of the inner cavity of the placement cavity 14, and the tip of the top of the support block 44 is designed in an arc transition;

[0041] In the initial state, the vertical diameter line of the roller 12 is always located on one side of the inner cavity of the placement cavity 14. This design enables the wood 3 to push the entire roller 12 toward the inner cavity of the placement cavity 14 through lateral force when it contacts the surface of the roller 12 and the buffer sleeve 13.

[0042] Working principle:

[0043] When the device is working, the mechanical arm drives the hoist to move above the multi-layer wooden boards on the ground, and gradually adjusts the posture of the hoist to move vertically downward. At this time, the wood 3 passes passively between the two groups of clamping blocks 2, and the support assembly 4 first abuts against the wood 3 on the uppermost layer, and pushes the support block 44 and the telescopic column 1 42 toward the inner wall of the fixed cylinder 1 41 through the inclined surface at the bottom of the support block 44, and continuously compresses the spring 1 43 until the arc tip of the support block 44 abuts against the side of the wood 3, and the wood 3 continues to move upward relative to the hoist, and abuts against the outer surfaces of the roller 12 and the buffer sleeve 13, and pushes the roller 12, the mounting frame 11 and the telescopic column 10 toward the inner wall of the fixed cylinder 8, and continuously compresses the spring 2 9 until the roller 12 completely enters the placement cavity 14 and abuts against the two sides of the wood 3, and the pressure of the roller 12 and the buffer sleeve 13 on the two sides of the wood 3 is generated by the spring 2 9, and the buffer sleeve 13 is squeezed and deformed;

[0044] When the mounting frame 11 drives the roller 12 to move along the axis of the telescopic column 2 10, it drives the gear 2 7 to move through the connecting rod 15, so that the gear 2 7 always keeps meshing with the gear 3 16. At the same time, the gear 2 7 makes a circular motion around the axis of the gear 3 16, and uses itself to synchronously mesh with the gear 1 6 to ensure the power connection from the motor 5 to the gear 3 16 and the roller 12.

[0045] Then, the motor 5 is started, and the gear 1 6, gear 2 7, gear 3 16 and roller 12 are driven to rotate. The roller 12 on the left side drives the buffer sleeve 13 to rotate counterclockwise, and the roller 12 on the right side drives the buffer sleeve 13 to rotate clockwise, so that the wood 3 abutting between the two groups of rollers 12 is lifted upward by the friction between the roller 12, the buffer sleeve 13 and the wood 3, so that a gap is generated between the wood 3 on the uppermost layer and the wood 3 on the second layer. At this time, the support block 44 moves toward one side of the wood 3 under the elastic force of the spring 1 43, and the mechanical arm drives the hoist to rise as a whole, making room for the support assembly 4, until the support block 44 is fully extended to the bottom of the clamped wood 3, thereby providing stable support for the wood 3.

[0046] Finally, the robot arm drives the elevator to the stacking position, moves downward, and contacts the stacked wood 3 or the limiting component at the stacking position through the inclined surface at the bottom of the support block 44, moves the support block 44 toward the side close to the inner cavity of the placement cavity 14, and then reverses the motor 5 to unload the wood 3, completing the entire stacking work.
