Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and particularly to an instrument conveying device for instrument production and preparation. Background Art

[0002] An instrument conveying device is a key device used to transport instrument parts, semi-finished products or finished products during the instrument production and preparation process. It can achieve automatic transmission of materials between different production stations, improve production efficiency, reduce manual labor intensity, and ensure the continuity and stability of the production process; among them, the conveying line body is the core part of the device, usually composed of belts, chains, rollers, etc.; the belt conveyor line has the advantages of stable operation, low noise, adjustable conveying speed, etc., and is suitable for conveying lighter instrument parts; the chain conveyor line has the characteristics of large load-bearing capacity and adaptability to complex lines, and is often used to convey heavier instruments or tooling fixtures; the roller conveyor line is suitable for instruments with regular shapes and flat bottoms, and can achieve fast conveying and flexible turning.

[0003] Currently, the Chinese invention patent application with the publication number CN116199001A proposes a loading conveyor for instrument production, including a loading flat plate placed on the inner bottom wall of the carriage. A fixed conveyor is fixedly arranged on the right side of the top of the loading flat plate, and a first conveyor belt is arranged on the fixed conveyor; a sliding conveyor is movably arranged left and right below the fixed conveyor, and the sliding conveyor is slidably arranged on the loading flat plate through pulleys. The packing box is conveyed by the first conveyor belt, falls onto the second conveyor belt, and then is received by the inclined conveyor belt through the second conveyor belt. The inclined conveyor belt conveys the packing box to the roller conveyor, and finally falls from the roller conveyor into the carriage to complete the stacking of the packing boxes; by controlling the height of the roller conveyor, the falling height of the packing box can be controlled. During stacking, the roller conveyor gradually rises from low to high, so that the packing boxes can be gradually stacked higher.

[0004] When the above structure uses the roller conveyor for packing box stacking operations, since the packing box freely falls from the end of the conveyor by its own gravity, there is a lack of buffering and speed control during the falling process, and it is easy to collide with the stacked boxes; such collisions are not only likely to cause damage and deformation to the surface of the boxes, but also pose a potential risk of damage to the instrument equipment inside the boxes; at the same time, because the roller conveyor only provides one-way conveying power and lacks the functions of precise positioning and attitude adjustment of the packing box, it is difficult to ensure the neat arrangement between the boxes during the stacking process, resulting in an uneven stacking surface; this uneven stacking method not only reduces the utilization rate of the carriage space, but also increases the safety hazards of the goods shifting and collapsing during transportation, seriously affecting the efficiency and quality of the stacking operation. Summary of the Invention

[0016] (III) Beneficial effects

[0017] The present invention provides an instrument conveying device for instrument production and preparation. It has the following beneficial effects:

[0018] (I). For this conveying device, through the conveying device, when the instrument conveying device is operating, the first motor and the second motor are simultaneously started to drive the first conveyor belt and the second conveyor belt to operate respectively; the design of the first conveyor belt and the second conveyor belt with a high-low dislocation allows the staff to easily load materials at a low position, reducing the labor intensity. The two conveyor belts are independently controlled and the speeds can be adjusted separately to adapt to different production rhythms.

[0019] (II). For this conveying device, through the guiding device, when the box is conveyed to the guiding device 40, according to the length of the box, the second cylinder 42 is started to push the guiding frame 41, so that the distance between the two guiding frames 41 corresponds to the length of the box. When the box is conveyed to the guiding device, the inclined plate 43 is used to guide the box between the two guiding frames to complete the guiding operation, so that the box can be guided to the stacking device, facilitating the stacking operation.

[0020] (3). For this conveying device, after the box enters the stacking device through the guiding device, the third motor is started to drive the pushing belt to move. The two sides of the box abut against the pusher plate, and the pusher plate cooperates with the conveying device to convey the box. When the box detaches from the conveying device, gravity causes the pusher plate to move downward, driving the sliding sleeve to move downward along the inclined rod and compressing the return spring. The pusher plate moves away from the box under the limitation of the inclined rod, facilitating the box to fall. During the fall, the return spring releases its potential energy, pushing the pusher plate to reset and continue to abut against the box, buffering and decelerating the box until it falls to the stacking position. Subsequent boxes repeat this process for stacking. When stacking and falling, the pusher plate is limited to prevent the boxes from colliding, reducing the risk of damage and enabling the stacked boxes to be neatly arranged.

[0021] (4). For this conveying device, through the intermittent device, when using the intermittent device, the driving device drives the rotating shaft and the turntable to rotate synchronously. The flipping rod hinged to the edge of the side wall of the turntable rotates with the turntable, and drives the baffle to slide reciprocally in the limiting frame through the hinge point. When the baffle slides to the top of the limiting frame, the box can continue to move forward on the conveying device. As the turntable continues to rotate, when the flipping drives the baffle to slide to the bottom of the limiting frame, it blocks the subsequent boxes from moving forward, realizing the pause of the conveying process, and enabling the boxes to maintain a reasonable spacing during the conveying process.

[0022] (5). For this conveying device, through the driving device, when using the intermittent device, the fourth motor is started to drive the sector gear disc to rotate on the inner wall of the housing. When the toothed part contacts the gear, it drives the gear and the rotating shaft to rotate. When the toothless part faces the gear, the gear and the rotating shaft pause rotating, realizing the intermittent rotation of the rotating shaft. The rotating shaft is connected to the turntable of the intermittent device to control the baffle to slide reciprocally in the limiting frame, intermittently blocking the boxes on the conveying device, avoiding overcrowding during conveying, reducing collision and extrusion, and improving the stability of instrument conveying and stacking. When the toothless part of the sector gear disc faces the gear and the gear stops rotating, the inner wall of the arc-shaped notch slides into contact with the side wall of the arc-shaped strip to limit the position of the gear and the rotating shaft. When the toothed part contacts the gear, the arc-shaped notch disengages from the arc-shaped strip. This sliding contact can quickly limit the rotation and avoid unnecessary rotation, enabling the baffle to stop at the bottom of the limiting frame during the intermittent stage to block the subsequent boxes.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-8, the present invention provides a technical solution: an instrument conveying device for instrument production and preparation, including a frame 10, a lifting device 20 is fixedly connected to the side wall of the frame 10, a conveying device 30 is fixedly connected to the top wall of the lifting device 20, and a guiding device 40 is further included. The side wall of the guiding device 40 is slidably connected to the side wall of the conveying device 30. The guiding device 40 includes a guiding frame 41. A second cylinder 42 is fixedly connected to the side wall of the conveying device 30. The output end of the second cylinder 42 is fixedly connected to the side wall of the guiding frame 41. An inclined plate 43 is fixedly connected to one end of the guiding frame 41 close to the conveying device 30. A stacking device 50 is slidably connected to the inner wall of the guiding frame 41; the stacking device 50 includes a pushing roller 51, a pushing belt 52 is rotatably connected to the side wall of the pushing roller 51. The side walls on both sides of the pushing roller 51 are rotatably connected to the inner wall of the guiding frame 41. A limiting groove 53 is formed in the side wall of the pushing belt 52. A blanking device 54 is slidably connected to the inner wall of the limiting groove 53; the blanking device 54 includes an inclined rod 541, a sliding sleeve 542 is slidably connected to the side wall of the inclined rod 541. A pushing plate 543 is fixedly connected to the side wall of the sliding sleeve 542. The side wall of the sliding sleeve 542 is slidably attached to the inner wall of the limiting groove 53. Circular sliders 544 are fixedly connected to both ends of the inclined rod 541. The side walls of the circular sliders 544 are slidably attached to the recessed parts of the inner wall of the guiding frame 41. A return spring 545 is arranged in the limiting groove 53. One end of the return spring 545 is fixedly connected to the bottom wall of the sliding sleeve 542, and the other end is fixedly connected to the top wall of the circular slider 544. A third motor 55 is fixedly connected to the top wall of the guiding frame 41. The output end of the third motor 55 is fixedly connected to the side wall of the pushing roller 51.

[0034] During use, start the lifting device 20 to lift the conveying device 30 to an appropriate height, move the entire conveying equipment so that the stacking device 50 corresponds to the position where stacking is required, and the box containing the instrument is conveyed through the conveying device 30; and according to the length of the box, start the second cylinder 42 to push the guiding frame 41 so that the distance between the two guiding frames 41 corresponds to the length of the box. When the box is conveyed to the guiding device 40, use the inclined plate 43 to guide the box between the two guiding frames 41. The third motor 55 drives the pushing roller 51 to rotate, thereby driving the pushing belt 52 to move. When the box enters the stacking device 50, start the third motor 55 to drive the pushing roller 51 to rotate, thereby driving the pushing belt 52 to move. The side walls on both sides of the box abut against the pushing plate 543, and cooperate with the conveying device 30 to convey the box. When the box disengages from the conveying device 30, the box drives the pushing plate 543 to move downward under the action of gravity. The pushing plate 543 drives the sliding sleeve 542 to move obliquely downward along the direction of the inclined rod 541, and causes the sliding sleeve 542 to compress the return spring 545. Therefore, when the pushing plate 543 moves downward, the sliding sleeve 542 moves obliquely downward along the direction of the inclined rod 541, which will cause the pushing plate 543 to move away from the box during the downward movement, so that the box disengages from the pushing plate 543, facilitating the box to fall. During the process of the box falling after disengaging from the pushing plate 543, the elastic potential energy accumulated by the compression of the return spring 545 is released, pushing the sliding sleeve 542 to slide reversely along the inclined rod 541. The pushing plate 543 is driven by the sliding sleeve 542 to move upward and reset synchronously, returning to the initial position and continuing to abut against the box, so that the box continuously abuts against and disengages from the pushing plate 543 during the falling process, buffering the box during the falling process and reducing its falling speed until it lands at the stacking position. After the box lands at the stacking position, the subsequent boxes continue to operate on the pushing belt 52 and repeat the above process to be stacked in sequence. The operator can adjust the lifting device 20 in real time according to the change in the stacking height to ensure that the conveying device 30 maintains a reasonable distance from the stacking surface; therefore, during the stacking and falling process of the box, it is difficult to collide under the limitation of the pushing plate 543, reducing the risk of damage to the box, and enabling the stacked boxes to land steadily at the stacking position, facilitating the boxes to be arranged neatly.

[0035] A limiting device 56 is fixedly connected to the inner wall of the bottom end of the guiding frame 41. The limiting device 56 includes a connecting shaft 561. Both ends of the connecting shaft 561 are fixedly connected to the inner wall of the bottom end of the guiding frame 41. A lever 562 is rotatably connected to the side wall of the connecting shaft 561. A torsion spring 563 is sleeved on the side wall of the connecting shaft 561. One end of the torsion spring 563 is fixedly connected to the side wall of the lever 562, and the other end is fixedly connected to the inner wall of the bottom end of the guiding frame 41. A contact plate 564 is slidably connected to the side wall of the bottom end of the guiding frame 41. An inclined opening 565 is formed in the side wall of the contact plate 564 on the side close to the conveying device 30. One end of the lever 562 is in contact with the side wall of the contact plate 564, and the other end is hinged to a connecting rod 566. The end of the connecting rod 566 away from the lever 562 is hinged to a limiting plate 567. The side wall of the limiting plate 567 is slidably connected to the inner wall of the bottom end of the guiding frame 41. The top wall of the limiting plate 567 is in contact with the bottom wall of the pushing plate 543; when a part of the box body disengages from the conveying device 30, the part of the box body that disengages from the conveying device 30 is likely to drive the pushing plate 543 to move downward under the action of gravity, causing the box body to tilt. To avoid this situation, the limiting device 56 is provided. When the box body is conveyed at the stacking device 50, both sides of the box body will abut against the inclined opening 565, and push the contact plate 564 to move away from the box body, and drive the lever 562 to rotate counterclockwise. Through the connecting rod 566, the torsion spring 563 is elastically deformed and stores potential energy. The lever 562 pulls the limiting plate 567 through the connecting rod 566, so that it slides along the inner wall of the bottom end of the guiding frame 41 until it fits tightly against the bottom wall of the pushing plate 543; at this time, the limiting plate 567 provides a stable support for the pushing plate 543, offsetting the downward pulling force generated when a part of the box body disengages from the conveying device 30, preventing the pushing plate 543 from moving downward in advance, and ensuring that the box body is horizontally and stably conveyed under the cooperation of the pushing belt 52 and the pushing plate 543; when the box body completely disengages from the conveying device 30, the contact plate 564 disengages from the box body, and the torsion spring 563 releases the stored elastic potential energy, driving the lever 562 to rotate clockwise and reset, pushing the limiting plate 567 to move back through the connecting rod 566, so that it will not affect the stacking operation of the pushing plate 543. The contact plate 564 slides and resets under the drive of the lever 562, and the inclined opening 565 is ready for limiting and guiding the subsequent box bodies again, improving the stacking accuracy.

[0036] The side wall of the conveying device 30 is fixedly connected with an intermittent device 60. The intermittent device 60 includes a limiting frame 61. The side wall of the limiting frame 61 is fixedly connected with the side wall of the conveying device 30. A baffle 62 is slidably connected to the side wall of the limiting frame 61. Flipping rods 63 are hinged at both ends of the baffle 62. The side wall of the conveying device 30 is fixedly connected with a housing 64. A rotating shaft 65 is rotatably connected to the inner wall of the housing 64. A turntable 66 is fixedly connected to the side wall of the rotating shaft 65. The edge of the side wall of the turntable 66 is hinged to the bottom end of the flipping rod 63. A driving device 67 is rotatably connected in the housing 64; The driving device 67 drives the rotating shaft 65 and the turntable 66 to rotate synchronously. The flipping rod 63 hinged to the edge of the side wall of the turntable 66 rotates along with the turntable 66, and drives the baffle 62 to slide reciprocally in the limiting frame 61 through the hinge point; When the baffle 62 slides to the top end of the limiting frame 61, the box body can continue to move forward on the conveying device 30. As the turntable 66 continues to rotate, when the flipping rod 63 drives the baffle 62 to slide to the bottom end of the limiting frame 61, it blocks the subsequent box body from moving forward, realizing the pause of the conveying process; Through such mechanical linkage, the intermittent device 60 realizes the control of the conveying rhythm of the box body, reduces the collision and extrusion caused by the continuous conveying of the box bodies being too close, enables the box bodies to maintain a reasonable distance during the conveying process, matches the operation rhythm of the subsequent stacking device 50, and improves the stability and reliability of the operation of the entire instrument conveying equipment.

[0037] The driving device 67 includes a sector gear disc 671. The side wall of the sector gear disc 671 is rotatably connected to the inner wall of the housing 64. A gear 672 is fixedly connected to the side wall of the rotating shaft 65. The teeth on the above-mentioned sector gear disc 671 are meshed with the gear 672. The side wall of the housing 64 is fixedly connected with a fourth motor 673. The output end of the fourth motor 673 is fixedly connected to the side wall of the sector gear disc 671.

[0038] Start the fourth motor 673 to drive the connected sector gear disc 671 to rotate on the inner wall of the housing 64; When the toothed part of the sector gear disc 671 rotates into contact with the gear 672, it will drive the gear 672 to rotate, so that the rotating shaft 65 rotates accordingly; When the toothless part of the sector gear disc 671 faces the gear 672, the gear 672 will stop rotating, and the rotating shaft 65 will also stop rotating accordingly; In this way, the rotating shaft 65 realizes intermittent rotation; The rotating shaft 65 is connected to the turntable 66 in the intermittent device 60, and further controls the baffle 62 to slide reciprocally in the limiting frame 61, realizing the intermittent blocking of the box body conveying on the conveying device 30; This can prevent the box bodies from being too dense during the conveying process, reduce the situation of collision and extrusion, and improve the stability of the entire instrument conveying and stacking process.

[0039] A turning block 674 is fixedly connected to the side wall of the rotating shaft 65, and an arc-shaped strip 675 is fixedly connected to the side wall of the sector gear disc 671. An arc-shaped notch 676 is formed at one end of the turning block 674 away from the rotating shaft 65. When the toothless part of the sector gear disc 671 faces the gear 672, the gear 672 will stop rotating. The inner wall of the arc-shaped notch 676 will be in sliding contact with the side wall of the arc-shaped strip 675 to limit the gear 672 and the rotating shaft 65. When the toothed part of the sector gear disc 671 contacts the gear 672, it will drive the gear 672 to rotate, and the arc-shaped notch 676 will disengage from the arc-shaped strip 675. This sliding contact can not only quickly limit the rotation of the gear 672 and the rotating shaft 65, avoiding unnecessary rotation caused by factors such as inertia, but also ensure that during the intermittent stage of the box conveying, the baffle 62 can stay at the bottom end of the limit frame 61 to block the subsequent boxes, ensuring that the boxes maintain a reasonable spacing on the conveying device 30.

[0040] Universal wheels 11 are fixedly connected to the bottom wall of the frame 10. The lifting device 20 includes a telescopic rod 21. The fixed end of the telescopic rod 21 is fixedly connected to the top wall of the frame 10. The fixed end of the telescopic rod 21 is fixedly connected to a first cylinder 22. The output end of the first cylinder 22 is fixedly connected to the telescopic end of the telescopic rod 21. The telescopic end of the telescopic rod 21 is fixedly connected to a top plate 23. Both ends of the top plate 23 are fixedly connected to the side walls of the conveying device 30. The universal wheels 11 facilitate the staff to easily push the equipment to the designated position, facilitating the flexible deployment and use of the equipment. When it is necessary to adjust the height of the conveying device 30, the first cylinder 22 is started. The output end of the first cylinder 22 pushes the telescopic end of the telescopic rod 21 to perform telescopic movement and drives the top plate 23 to rise and fall, thereby realizing the adjustment of the height of the conveying device 30, enabling the lifting device 20 to adjust the height of the conveying device 30 so that the equipment can be better docked with other production links or stacking positions.

[0041] The conveying device 30 includes a first side plate 31. The bottom wall of the first side plate 31 is fixedly connected to the top wall of the lifting device 20. A first conveyor wheel 32 is rotatably connected to the side wall of the first side plate 31. A first conveyor belt 33 is rotatably connected to the side wall of the first conveyor wheel 32. A first motor 34 is fixedly connected to the side wall of the first side plate 31. The output end of the first motor 34 is fixedly connected to the first conveyor wheel 32. A second conveyor wheel 35 is rotatably connected to one end of the first side plate 31 away from the stacking device 50. Two ends of the second conveyor wheel 35 are rotatably connected to second side plates 36. A second conveyor belt 37 is rotatably connected to the side wall of the second conveyor wheel 35. A second motor 38 is fixedly connected to the side wall of the second side plate 36. The output end of the second motor 38 is fixedly connected to the side wall of the second conveyor wheel 35. When the instrument conveying equipment is operating, first start the first motor 34, and its output end drives the first conveyor wheel 32 fixedly connected thereto to rotate. The rotation of the first conveyor wheel 32 drives the first conveyor belt 33 connected thereto to operate, providing conveying power for the boxes placed on the first conveyor belt 33. At the same time, start the second motor 38, which drives the second conveyor wheel 35 to rotate, and then the second conveyor belt 37 starts to operate; the first conveyor belt 33 is at a high position, one end of the second conveyor belt 37 is at a low position, and the other end corresponds to the first conveyor belt 33 and is at a high position. The guiding device 40 and the stacking device 50 are both located at the first conveyor belt 33. When conveying the boxes, the staff can place the boxes on the second conveyor belt 37 at a low position for conveying and convey them to a high position. When the boxes reach the first conveyor belt 33, the first conveyor belt 33 then continues to convey the boxes until the boxes are conveyed to the stacking device 50. Therefore, the setting of the conveying device 30 enables the staff to easily place the boxes at a low position, reducing the labor intensity and improving the operation safety and convenience; the two sections of conveyor belts are independently driven and the speed can be adjusted as needed, capable of adapting to different conveying rhythms and working conditions.

[0042] A sliding device 39 is slidably connected to the side wall of the frame 10. The sliding device 39 includes a hinged rod 391. The side wall of the hinged rod 391 is hinged to the second side plate 36. The bottom wall of the hinged rod 391 is in sliding fit with the top wall of the frame 10. A runner 392 is rotatably connected to the side wall of the hinged rod 391.

[0043] When the lifting device 20 adjusts the height of the first side plate 31, the height of one end of the second side plate 36 changes and the other end flips. To adapt to the flipping of the second side plate 36, the hinged rod 391 hinged to the second side plate 36 will move accordingly with the movement of the second side plate 36 to compensate for the position change caused by the flipping of the second side plate 36. The bottom wall of the hinged rod 391 is in sliding fit with the top wall of the frame 10, making it difficult for the hinged rod 391 to shake or flip during the movement. The runner 392 at the bottom end of the hinged rod 391 will slide on the frame 10, making the sliding process smoother.

[0044] Working principle:

[0045] In use, the conveying device consists of a frame 10, a lifting device 20, a conveying device 30, a guiding device 40, a stacking device 50 and an intermittent device 60. Among them, the lifting device 20 is used to lift the conveying device 30 to an appropriate height. The conveying device 30 is used to convey the boxes containing instruments. The intermittent device 60 is used to control the conveying rhythm of the boxes on the conveying device 30. The guiding device 40 cooperates with the conveying device 30 to guide the boxes to the stacking device 50, and the stacking device 50 stacks the boxes.

[0046] Among them, the lifting device 20 includes a telescopic rod 21, a first cylinder 22 and a top plate 23. When the height of the conveying device 30 needs to be adjusted, the first cylinder 22 is started. The output end of the first cylinder 22 pushes the telescopic end of the telescopic rod 21 to perform telescopic movement, driving the top plate 23 to move up and down, thereby realizing the adjustment of the height of the conveying device 30, so that the lifting device 20 can adjust the height of the conveying device 30.

[0047] The conveying device 30 includes a first side plate 31, a first conveyor wheel 32, a first conveyor belt 33, a first motor 34, a second conveyor wheel 35, a second side plate 36, a second conveyor belt 37 and a second motor 38. When the instrument conveying device is running, the first motor 34 is started first. Its output end drives the first conveyor wheel 32 fixedly connected thereto to rotate. The first conveyor wheel 32 rotates to drive the first conveyor belt 33 connected thereto to operate, providing conveying power for the boxes placed on the first conveyor belt 33. At the same time, the second motor 38 is started, which drives the second conveyor wheel 35 to rotate, and then the second conveyor belt 37 starts to operate. The first conveyor belt 33 is at a high position. One end of the second conveyor belt 37 is at a low position, and the other end corresponds to the first conveyor belt 33 and is at a high position. The guiding device 40 and the stacking device 50 are both located at the first conveyor belt 33. When conveying the boxes, the staff can place the boxes on the second conveyor belt 37 at a low position for conveying and convey them to a high position. When the boxes reach the first conveyor belt 33, the first conveyor belt 33 continues to convey the boxes until the boxes are conveyed to the stacking device 50. Therefore, the setting of the conveying device 30 enables the staff to easily place the boxes at a low position, reducing the labor intensity and improving the operation safety and convenience. The two conveyor belts are independently driven and the speed can be adjusted as needed, which can adapt to different conveying rhythms and working conditions.

[0048] The sliding device 39 includes a hinged rod 391 and a runner 392; when the lifting device 20 adjusts the height of the first side plate 31, the height of one end of the second side plate 36 changes, and the other end flips. To adapt to the flipping of the second side plate 36, the hinged rod 391 hinged to the second side plate 36 will move accordingly with the movement of the second side plate 36 to compensate for the position change caused by the flipping of the second side plate 36. The bottom wall of the hinged rod 391 is in sliding contact with the top wall of the frame 10, making it difficult for the hinged rod 391 to shake or flip during the movement. The runner 392 at the bottom end of the hinged rod 391 will slide on the frame 10 to make the sliding process smoother.

[0049] The guiding device 40 includes a guiding frame 41, a second air cylinder 42, and an inclined plate 43; when the box is conveyed to the guiding device 40, according to the length of the box, the second air cylinder 42 is started to push the guiding frame 41 so that the distance between the two guiding frames 41 corresponds to the length of the box. When the box is conveyed to the guiding device 40, the inclined plate 43 is used to guide the box between the two guiding frames 41, so that the box can be conveyed to the stacking device 50 more accurately during the conveying process.

[0050] The stacking device 50 includes a pushing roller 51, a pushing belt 52, a limiting groove 53, a blanking device 54, a third motor 55, and a limiting device 56; when the box is conveyed to the stacking device 50, the third motor 55 is started to drive the pushing roller 51 to rotate, and then drive the pushing belt 52 to move. When the box leaves the conveying device 30, the blanking device 54 cooperates with the gravity of the box to perform a blanking operation to complete the stacking operation. The limiting device 56 is used to make it difficult for the box to shake or shift during the blanking process.

[0051] The blanking device 54 includes an inclined rod 541, a sliding sleeve 542, a pushing plate 543, a circular slider 544, and a return spring 545; when the box enters the stacking device 50, the third motor 55 is started to drive the pushing roller 51 to rotate, thereby driving the pushing belt 52 to move. The side walls on both sides of the box abut against the pushing plate 543 and cooperate with the conveying device 30 to convey the box. When the box disengages from the conveying device 30, the box drives the pushing plate 543 to move downward under the action of gravity. The pushing plate 543 drives the sliding sleeve 542 to move obliquely downward along the direction of the inclined rod 541, and the sliding sleeve 542 compresses the return spring 545. Therefore, when the pushing plate 543 moves downward, the sliding sleeve 542 moves obliquely downward along the direction of the inclined rod 541, which will cause the pushing plate 543 to move away from the box during the downward movement, so that the box disengages from the pushing plate 543, facilitating the box to fall. During the process of the box falling after disengaging from the pushing plate 543, the elastic potential energy accumulated by the compression of the return spring 545 is released, pushing the sliding sleeve 542 to slide reversely along the inclined rod 541. The pushing plate 543 is driven by the sliding sleeve 542 to move upward and reset synchronously, returning to the initial position and continuing to abut against the box, so that the box continuously abuts against and disengages from the pushing plate 543 during the falling process, buffering the box during the falling process and reducing its falling speed until it lands at the stacking position. After the box lands at the stacking position, the subsequent boxes continue to operate on the pushing belt 52 and repeat the above process to stack in sequence. The operator can adjust the lifting device 20 in real time according to the change in the stacking height to ensure a reasonable distance between the conveying device 30 and the stacking surface; therefore, during the stacking and falling process of the box, it is difficult to collide under the limitation of the pushing plate 543, reducing the risk of damage to the box, and moreover, enabling the stacked boxes to land at the stacking position more stably, facilitating the boxes to be arranged neatly.

[0052] The limiting device 56 includes a connecting shaft 561, a lever 562, a torsion spring 563, a contact plate 564, an inclined opening 565, a connecting rod 566, and a limiting plate 567. When the box part detaches from the conveying device 30, the part of the box that detaches from the conveying device 30 is likely to drive the pusher plate 543 to move downward under the action of gravity, causing the box to tilt. To avoid this situation, the limiting device 56 is provided. When the box is conveyed at the stacking device 50, both sides of the box will abut against the inclined opening 565, and push the contact plate 564 to move away from the box, driving the lever 562 to rotate counterclockwise. Through the connecting rod 566, the torsion spring 563 is elastically deformed and stores potential energy. The lever 562 pulls the limiting plate 567 through the connecting rod 566, causing it to slide along the inner wall of the bottom end of the guiding frame 41 until it closely fits against the bottom wall of the pusher plate 543. At this time, the limiting plate 567 provides a stable support for the pusher plate 543, offsetting the downward pulling force generated when the box part detaches from the conveying device 30, preventing the pusher plate 543 from moving downward in advance, and ensuring that the box is horizontally and stably conveyed under the combined action of the pushing belt 52 and the pusher plate 543. When the box completely detaches from the conveying device 30, the contact plate 564 detaches from the box, and the torsion spring 563 releases the stored elastic potential energy, driving the lever 562 to rotate clockwise and return to its original position. Through the connecting rod 566, the limiting plate 567 is pushed back, so that it will not affect the stacking operation of the pusher plate 543. The contact plate 564 slides back under the drive of the lever 562, and the inclined opening 565 is ready again for limiting and guiding the subsequent boxes, improving the stacking accuracy.

[0053] The intermittent device 60 includes a limiting frame 61, a baffle 62, a flipping rod 63, a housing 64, a rotating shaft 65, a turntable 66, and a driving device 67. The driving device 67 drives the rotating shaft 65 and the turntable 66 to rotate synchronously. The flipping rod 63 hinged to the edge of the side wall of the turntable 66 rotates with the turntable 66, and drives the baffle 62 to reciprocate in the limiting frame 61 through the hinge point. When the baffle 62 slides to the top end of the limiting frame 61, the box can continue to move forward on the conveying device 30. As the turntable 66 continues to rotate, when the flipping rod 63 drives the baffle 62 to slide to the bottom end of the limiting frame 61, it blocks the subsequent boxes from moving forward, realizing the pause of the conveying process. Through such mechanical linkage, the intermittent device 60 controls the conveying rhythm of the boxes, reducing collisions and squeezes caused by the continuous conveying of the boxes being too close, so that the boxes can maintain a reasonable distance during the conveying process.

[0054] The drive device 67 includes a sector gear disk 671, a gear 672, a fourth motor 673, a flipping block 674, an arc-shaped strip 675, and an arc-shaped notch 676. Starting the fourth motor 673 drives the connected sector gear disk 671 to rotate on the inner wall of the housing 64. When the toothed part of the sector gear disk 671 rotates into contact with the gear 672, it drives the gear 672 to rotate, thereby causing the rotating shaft 65 to rotate accordingly. When the toothless part of the sector gear disk 671 faces the gear 672, the gear 672 stops rotating, and the rotating shaft 65 also pauses rotating. In this way, the rotating shaft 65 realizes intermittent rotation. The rotating shaft 65 is connected to the turntable 66 in the intermittent device 60, and further controls the baffle 62 to slide reciprocally within the limit frame 61, achieving intermittent blocking of the boxes on the conveying device 30. This can prevent the boxes from being too dense during the conveying process, reduce collisions and squeezes, and improve the stability of the entire instrument conveying and stacking process. When the toothless part of the sector gear disk 671 faces the gear 672, the gear 672 stops rotating, and the inner wall of the arc-shaped notch 676 slides into contact with the side wall of the arc-shaped strip 675 to limit the gear 672 and the rotating shaft 65. When the toothed part of the sector gear disk 671 rotates into contact with the gear 672, it drives the gear 672 to rotate, and the arc-shaped notch 676 disengages from the arc-shaped strip 675. This sliding contact can not only quickly limit the rotation of the gear 672 and the rotating shaft 65, avoiding unnecessary rotation caused by factors such as inertia, but also ensure that during the intermittent stage of box conveying, the baffle 62 can stay at the bottom of the limit frame 61 to block subsequent boxes.
