Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper transportation equipment, and specifically discloses a corrugated paper raw material transfer device. Background Technology

[0002] Corrugated cardboard, as a widely used packaging material, is mainly produced from corrugated paper rolls made from various fiber base papers. These rolls have different diameters and are cylindrical in shape. In paper mills, cardboard processing plants, and warehousing and logistics centers, they are usually stored in multi-layer stacks to make full use of the three-dimensional space. The transfer process is an important step connecting warehousing and production lines, and is usually completed by forklifts and clamp trucks.

[0003] Existing transfer devices, due to the cylindrical shape of the corrugated paper rolls, have small interlayer contact areas and limited friction. Furthermore, the overall center of gravity of the stack is relatively high. When the gripper contacts, clamps, and lifts the rolls located on the top layer of the stack, the applied squeezing force, mechanical vibration, and friction generated during the lifting process can easily disrupt the static balance of the stack. This can easily cause the rolls to be gripped to roll, which in turn can cause the rolls stacked below to slip and tip over due to instability, posing a safety hazard. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a corrugated paper raw material transfer device to solve the technical problem that when the existing transfer device is clamping the corrugated paper roll located on the upper layer of the stack, the operation disturbance can easily cause the stack below to become unstable and cause a chain of collapses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated paper raw material transfer device, including a movable base, an installation frame on the movable base, a slidable sliding block inside the installation frame, a lifting clamping mechanism on the sliding block for clamping corrugated paper rolls located on the upper stack, a lifting guarding mechanism on the side wall of the installation frame for preventing the lower stacked rolls from tipping over when clamping the upper stacked corrugated paper rolls, two linkage mechanisms on the lifting guarding mechanism for cooperating with the lifting clamping mechanism, and a driving mechanism on the installation frame for driving the sliding block to move within the installation frame.

[0006] In this solution, the lifting and gripping mechanism installed on the mounting frame can, through the precise coordination of two linkage mechanisms, drive the lifting and guarding mechanism to move synchronously in real time when performing the operation of gripping the corrugated paper roll located on the upper layer of the stack. The lifting and guarding mechanism then forms an effective protection around the stack below the roll to be picked up, thereby fundamentally solving the problem of chain-like tipping of the lower stacked rolls caused by the disruption of force balance during the extraction of the upper layer of rolls. Compared with existing transfer devices, most of which have single functions and rely on operator experience or additional, non-integrated safety measures to prevent tipping, this device deeply integrates active gripping and passive protection, realizing the simultaneous completion of the two major functions of extraction and protection in a single operation process.

[0007] Furthermore, the lifting and gripping mechanism includes two fixed frames. Two sliding grooves are provided on the mounting frame. The two fixed frames are disposed on the sliding block. One end of each of the two fixed frames is fixedly connected to the sliding block. The other ends of the two fixed frames pass through the two sliding grooves respectively. A slidable first crossbar is provided between the two fixed frames. The first crossbar is provided with a mechanical gripper for gripping corrugated paper rolls. One of the two fixed frames is provided with a first screw. One end of the first screw is rotatably connected to the inner wall of the fixed frame. The other end of the first screw is threadedly connected to the first crossbar and passes through the fixed frame. A first motor is provided on the fixed frame. The power output shaft of the first motor is fixedly connected to the end of the first screw that passes through the fixed frame.

[0008] In this solution, the first screw is driven to rotate by the first motor, which in turn directly controls the first crossbar, which is threadedly connected to the first screw, to move stably between the two fixed frames. Compared with the chain, hydraulic or wire rope lifting mechanisms commonly used in the prior art, the screw transmission method has significant advantages such as smooth transmission, good self-locking, accurate positioning and large load-bearing capacity.

[0009] Furthermore, the lifting enclosure mechanism includes two sliding frames, which are fixedly connected to the mounting frame. Between the two sliding frames, a plurality of tipping protection units are provided to prevent the stack below from becoming unstable and tipping over when the upper corrugated paper roll is clamped.

[0010] In this solution, multiple tipping protection units can move flexibly along the sliding frame to form a dynamically adjustable protective barrier that can follow the lifting and clamping mechanism.

[0011] Furthermore, each of the multiple tipping protection units includes a second crossbar, which is slidably disposed between two sliding frames. A traction rope is disposed below the second crossbar, one end of which is fixedly connected to the lower part of the second crossbar, and the other end of which is fixedly connected to the upper end face of the adjacent lower second crossbar. A limit frame is disposed on the second crossbar, and a slidable limit block is disposed within the limit frame. Several springs are disposed within the limit frame, one end of which is fixedly connected to the inner wall of the limit frame, and the other end of which is fixedly connected to the limit block. An arc-shaped plate that can fit against the outer wall of the corrugated paper roll is fixedly connected to the limit block.

[0012] In this solution, multiple tipping protection units achieve coordinated lifting and lowering motion through the sliding arrangement of the second crossbar within the sliding frame and the up-and-down linkage of the traction rope. The traction rope connects the second crossbars of each layer, forming a linkage that allows all tipping protection units to rise and fall synchronously with the lifting and gripping mechanism. This automatically adapts to different corrugated paper roll stacking heights without individual drive or adjustment. When the mechanical gripper descends, the traction is released, and the tipping protection units fall back orderly along the sliding frame under their own weight. Compared to existing technologies that use fixed baffles or require independently controlled protective devices, this device achieves comprehensive and adaptive protective coverage through a simple mechanical linkage structure. Combined with the spring buffer and arc-shaped plate fitting structure, it ensures the reliability of the protection while significantly simplifying the control system and mechanical structure, reducing manufacturing costs and maintenance difficulty.

[0013] Furthermore, both of the linkage mechanisms include a fixing block, which is fixedly connected to the first crossbar. An L-shaped rod is provided on the second crossbar, with one end of the L-shaped rod fixedly connected to the second crossbar and the other end of the L-shaped rod passing through the fixing block.

[0014] In this scheme, when the second motor drives the sliding block to move horizontally, the fixed block moves synchronously with the first crossbar. At this time, the L-shaped rod slides freely within the fixed block. The two only undergo relative displacement and do not produce linkage, ensuring that the tipping protection unit remains stationary during horizontal movement. Only when the first crossbar moves up and down will the fixed block drive the L-shaped rod to move up and down synchronously, thereby driving the protection mechanism to move. The simple mechanical coupling ensures that parallel movements do not interfere with each other and has the advantage of synchronous lifting and lowering.

[0015] Furthermore, the driving mechanism includes a second screw, one end of which is rotatably connected to the inner wall of the mounting frame, and the other end of which is threadedly connected to the sliding block and passes through the mounting frame. A second motor is provided on the side wall of the mounting frame, and the power output shaft of the second motor is fixedly connected to the end of the second screw that passes through the mounting frame.

[0016] In this solution, the second screw is driven to rotate by the second motor, which is directly converted into the linear movement of the sliding block within the mounting frame. The screw drive has the advantages of smooth transmission, accurate positioning, and good self-locking, avoiding positioning errors caused by belt slippage, chain vibration, or air pressure fluctuations.

[0017] The working principle and beneficial effects of this solution are as follows: When it is necessary to transfer and stack the upper layer of corrugated paper rolls, the moving base is first driven to the target corrugated paper roll stack position. The second motor is started to drive the second screw to rotate, which drives the sliding block and the fixed frame to make the mechanical gripper horizontally approach the corrugated paper roll. At this time, the fixed block moves with the first crossbar and slides relative to the L-shaped bar. Then, the first motor is started to drive the first screw, which makes the first crossbar lift the fixed block, and then lift the L-shaped bar and the second crossbar. The traction rope on the tilt protection unit drives the arc plate to be lifted synchronously to the working height. The moving base is finely adjusted to make the arc plate fit against the lower corrugated paper roll stack. The spring buffer avoids squeezing damage. After the roll is gripped, the first motor and the second motor reverse and transfer the roll to the support seat. At this time, the second crossbar descends back to the initial position, which solves the technical problem of the existing transfer device causing the lower stack to become unstable and tilt when gripping the upper layer of corrugated paper rolls due to operational disturbance.

[0021] The following detailed description illustrates the specific implementation method: Example

[0022] like Figures 1 to 5 As shown, a corrugated paper raw material transfer device is disclosed, including a movable base 1, a mounting frame 2, a sliding block 3, a lifting clamping mechanism, a support base 4, a lifting guarding mechanism, two linkage mechanisms, and a drive mechanism. The mounting frame 2 is fixedly connected to the upper end face of the movable base 1. A sliding block 3 is provided inside the mounting frame 2. The lifting clamping mechanism is provided on the sliding block 3. The lifting clamping mechanism is used to clamp the corrugated paper roll located on the upper layer of the stack. The support base 4 is installed on the mounting frame 2. The support base 4 is used to support the corrugated paper roll after clamping. The lifting guarding mechanism is provided on the side wall of the mounting frame 2. The lifting guarding mechanism is used to prevent the stack below from tipping over when clamping the corrugated paper roll on the upper layer of the stack. Two linkage mechanisms are provided on the lifting guarding mechanism. Both linkage mechanisms can cooperate with the lifting clamping mechanism to drive the lifting guarding mechanism to move. The drive mechanism is provided on the mounting frame 2. The drive mechanism is used to drive the sliding block 3 to move within the mounting frame 2. The movable base 1 is prior art.

[0023] like Figure 1 As shown, the lifting and gripping mechanism includes two fixed frames 5, a first crossbar 6, a first screw 7, a mechanical gripper 8, a first mounting frame 9, and a first motor 10. Two sliding grooves 11 are provided on the mounting frame 2. Two fixed frames 5 are provided on the sliding block 3. One end of each fixed frame 5 is fixedly connected to the upper surface of the sliding block 3, and the other end of each fixed frame 5 passes through the two sliding grooves 11 respectively. The first crossbar 6 is slidably mounted between the two fixed frames 5. The mechanical gripper 8 is provided on the first crossbar 6 and is used to grip corrugated paper rolls. One of the two fixed frames 5 is provided with a first screw 7. One end of the first screw 7 is rotatably connected to the inner wall of the fixed frame 5, and the other end of the first screw 7 is threadedly connected to the first crossbar 6 and passes through the fixed frame 5. The first mounting frame 9 is fixedly connected to the fixed frame 5, and the first motor 10 is mounted on the first mounting frame 9. The power output shaft of the first motor 10 is fixedly connected to the end of the first screw 7 that passes through the fixed frame 5. The mechanical gripper 8 is existing technology.

[0024] like Figure 2 As shown, the lifting enclosure mechanism includes two sliding frames 12 and several tilt protection units. Two sliding frames 12 are provided at one end of the mounting frame 2 away from the two fixed frames 5. Multiple tilt protection units that can slide and lift are provided on the opposite side walls of the two sliding frames 12. The multiple tilt protection units are used to unfold layer by layer to form a ring-shaped protective barrier when the upper corrugated paper roll is clamped, so as to prevent the chain of tilting caused by the instability of the stack below.

[0025] like Figure 2 and Figure 3 As shown, each of the multiple tipping protection units includes a second crossbar 13, a traction rope 14, a limiting frame 15, a limiting block 16, several springs 17, and an arc plate 18. The second crossbar 13 is slidably clamped between two sliding frames 12. Adjacent second crossbars 13 are connected by a traction rope 14. One end of the traction rope 14 is fixed to the lower end face of the upper second crossbar 13, and the other end of the traction rope 14 is connected to the upper end face of the adjacent lower second crossbar 13. The end of the second crossbar 13 away from the first crossbar 6 is fixedly connected to the limiting frame 15. The limiting block 16 is slidably fitted inside the limiting frame 15. Several springs 17 are provided inside the limiting frame 15. One end of each spring 17 is fixedly connected to the inner wall of the limiting frame 15, and the other end of each spring 17 is fixedly connected to the limiting block 16. The end of the limiting block 16 away from the limiting frame 15 is fixedly connected to an arc plate 18. The inner arc surface of the arc plate 18 can fit against the outer wall of the corrugated paper roll.

[0026] like Figure 5 As shown, both linkage mechanisms include a fixed block 19 and an L-shaped rod 20. The fixed block 19 is fixedly connected to the lower end face of the first crossbar 6, and the L-shaped rod 20 is provided on the second crossbar 13. One end of the L-shaped rod 20 is fixedly connected to the upper end face of the second crossbar 13, and the other end of the L-shaped rod 20 passes through the fixed block 19. A sliding pair is formed between the L-shaped rod 20 and the fixed block 19.

[0027] like Figure 4 As shown, the drive mechanism includes a second screw 21, a second mounting bracket 22, and a second motor 23. The second screw 21 is provided on the mounting frame 2. One end of the second screw 21 is rotatably connected to the inner wall of the mounting frame 2, and the other end of the second screw 21 is threadedly connected to the sliding block 3 and passes through the mounting frame 2. The second mounting bracket 22 is fixedly connected to the end of the mounting frame 2 away from the two sliding frames 12. The second motor 23 is mounted on the second mounting bracket 22, and the power output end of the second motor 23 is fixedly connected to the end of the second screw 21 that passes through the mounting frame 2.

[0028] In practice When it is necessary to transfer the corrugated paper roll located on the top layer of the stack, first move the base 1 to the target stack position of the roll, and then start the second motor 23 on the second mounting frame 22. The second motor 23 drives the second screw 21 to rotate clockwise. When the second screw 21 rotates clockwise, it synchronously drives the sliding block 3 to move along the mounting frame 2 towards the corrugated paper roll. The sliding block 3 synchronously drives the two fixed frames 5 to move under the guidance of the slide groove 11. When the two fixed frames 5 move, they simultaneously drive the mechanical gripper 8 on the first crossbar 6 to move closer to the corrugated paper roll. When the first crossbar 6 moves, the fixed block 19 located below will move accordingly. Since the L-shaped rod 20 passes through the fixed block 19, the fixed block 19 and the L-shaped rod 20 are in a sliding fit relationship. Therefore, when the first crossbar 6 drives the fixed block 19 to move, it will not drive the L-shaped rod 20 to move synchronously. The fixed block 19 and the L-shaped rod 20 only have relative displacement. At this time, by activating the first motor 10 on the first mounting bracket 9, the first motor 10 drives the first screw 7 to rotate clockwise. The rotation of the first screw 7 causes the first crossbar 6 to move away from the mounting frame 2 between the two fixed frames 5. During the movement of the first crossbar 6, the fixed block 19 located below will rise simultaneously. As the fixed block 19 moves upward, since the L-shaped rod 20 and the fixed block 19 are only in a sliding fit relationship, the rising of the fixed block 19 will cause the L-shaped rod 20 to rise. During the movement of the L-shaped rod 20, the second crossbar 13 will rise simultaneously. The second crossbar 13 moves upward between the two sliding frames 12. During the upward movement, the second crossbar 13 will gradually drive the traction rope 14 located below to move. The second crossbar 13 pulls the traction rope 14 connected to the other second crossbar 13 below it. As the traction rope 14 gradually tightens, the second crossbar 13 located below is driven to move upward synchronously. Since multiple tipping protection units are provided, each second crossbar 13 is driven to rise step by step with the first crossbar 6 through the L-shaped bar 20. When the mechanical gripper 8 on the first crossbar 6 reaches the height required to grip the corrugated paper raw material, the first motor 10 stops. At this point, the moving base 1 can be activated again to move the arc-shaped plate 18 on the second crossbar 13 close to the outer wall of the corrugated paper roll stack below the corrugated paper roll to be picked up. When the arc-shaped plate 18 contacts the corrugated paper roll, the limiting block 16 on the arc-shaped plate 18 slides along the limiting frame 15 and compresses the spring 17 to form a flexible buffer, avoiding rigid compression that could damage the corrugated paper roll. Then, the second screw 21 is driven by the second motor 23 to move the mechanical gripper 8 laterally to the roll position. At this time, the mechanical gripper 8 is controlled to open its gripping arms, causing the opened mechanical gripper 8 to move laterally. Move the mechanical gripper 8 to both sides of the corrugated paper roll, and then control the mechanical gripper 8 to close and firmly clamp the corrugated paper roll. After clamping, the second motor 23 reverses and drives the clamped corrugated paper roll to move away from the stack of corrugated paper rolls. Then, the first motor 10 reverses and drives the second crossbar 13 to move closer to the mounting frame 2, placing the clamped corrugated paper roll on the support base 4. When the second crossbar 13 descends, it will simultaneously drive the L-shaped bar 20 to move. The L-shaped bar 20 drives the second crossbar 13 to move downward and return to the initial position.

[0029] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
