Description

Technical Field

[0001] The invention relates to the technical field of tire stacking, and in particular to a stacking device used for tire production. Background Art

[0002] Tire stacking is an important part of warehouse management and logistics operations, which involves how to stack tires safely and efficiently. The correct stacking method can not only improve space utilization, but also ensure the quality and safety of tires. Most of the existing tire stackers are installed on the conveyor line to clamp and lift the tires to be stacked. At the same time, the conveyor device conveys the next tire to the bottom of the clamped tire. The stacker places the clamped tire on the upper side of the tire on the conveyor device, and then clamps and lifts the two tires. This cycle continues until the stacking quantity is reached and the tires are conveyed to the next step by the conveyor device. However, when the stacker performs tire clamping and lifting operations, the weight of the tire will be directly transmitted to the slide rail part of the stacker through the clamp, thereby forming obvious stress concentration at the key contact points of the slide rail. In the long run, with the frequent use of the stacker, these stress accumulations will cause the slide rail material to gradually produce plastic deformation. The deformation of the slide rail will not only reduce its structural integrity and load-bearing capacity, but even cause the slide rail to become stuck, resulting in the stacker being unable to accurately clamp and place the tire, thereby affecting the efficiency and safety of the entire stacking operation.

DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0021] When the stacker is clamping and lifting tires, the weight of the tires is transferred to the stacker's slide rails through the clamps, causing significant stress concentration in this area. As time goes by and the equipment is used frequently, this continuous stress will gradually deform the slide rails. Eventually, the deformation of the slide rails will cause the stacker to get stuck, making it unable to continue to effectively complete the tire stacking task.

[0022] A stacking device for tire production, such as Figure 1-Figure 3 As shown, it includes: a conveying base 1; a fixed plate 2, fixedly connected to the conveying base 1; a first motor 3, fixedly connected to the fixed plate 2, and the output shaft of the first motor 3 is rotatably connected to the fixed plate 2, and the output shaft of the first motor 3 is provided with a spur gear 4; a sliding plate 5, limited slidingly connected to the fixed plate 2, the sliding plate 5 is fixedly connected with a rack rack 6, and the rack rack 6 is meshed with the spur gear 4; a clamping plate 7, having two, both of which are limitedly slidably connected to the sliding plate 5; a force dissipation shaft 8, slidably connected to the sliding plate 5, and the two clamping plates 7 are slidably connected to the force dissipation shaft 8; a driving component, arranged on the sliding plate 5, for driving the two clamping plates 7 to move in opposite or opposite directions; a detection clamping component, having two, respectively arranged on the two clamping plates 7, for stably clamping the tire; a pushing component, arranged on the fixed plate 2, for pulling the force dissipation shaft 8 to offset the gravity of the tire.

[0023] In the above scheme, the conveying base 1 is composed of a support frame, a conveying device, a control system and a deviation correction device, wherein the conveying device is a roller conveying device with high flexibility, and can adapt to various application requirements such as turning, diversion and merging by adjusting the roller spacing and configuration. The deviation correction device is a guide wheel, which contacts the tire surface through the guide wheel and gradually guides the tire back to the stacking position through friction, causing little damage to the tire surface, and can handle tires of different sizes. The first motor 3 is electrically connected to the control system, and the fixed plate 2 is located on the upper side of the conveying base 1, and the fixed plate 2 is The vertical distance from the top to the conveying base 1 is greater than the thickness of the tire, so that the tire can be smoothly conveyed to the stacking position. The exterior of the energy dissipation shaft 8 is polished to reduce the friction between the energy dissipation shaft 8 and the clamping plate 7. The energy dissipation shaft 8 is made of high-strength steel and has a certain structural strength. It is used to transmit the force to offset the weight of the tire. By applying tension to the energy dissipation shaft 8 when clamping the tire stack, the stress concentration at the connection between the fixed plate 2 and the sliding plate 5 and the connection between the clamping plate 7 and the sliding plate 5 is offset, avoiding deformation caused by long-term stress concentration, which causes the sliding plate 5 and the two clamping plates 7 to get stuck.

[0024] Specifically, Figure 3 As shown, the driving assembly includes: a second motor 201, fixedly connected to the sliding plate 5; a screw 202, arranged on the output shaft of the second motor 201, and the screw 202 is rotatably connected to the sliding plate 5, and two symmetrically distributed sections of threads are distributed on the screw 202, and the screw 202 is threadedly connected to the two clamping plates 7 through the two sections of threads.

[0025] In the above scheme, the second motor 201 is electrically connected to the control system, and the material of the lead screw 202 is high-strength steel to improve its structural strength and extend its service life. The pitch of the two symmetrically distributed threads is the same, and the spiral directions of the threads are opposite, which are used to make the two clamping plates 7 move equidistantly towards or away from each other to achieve clamping of the tire.

[0026] Specifically, Figure 3 and Figure 4 As shown, the detection clamping assembly includes: a plurality of detection plates 301, each of which is slidably connected to an adjacent clamping plate 7, and two clamping rollers 302 are rotatably connected to the detection plate 301; first elastic elements 303, the same number as the detection plates 301, are respectively arranged between adjacent detection plates 301 and adjacent clamping plates 7.

[0027] In the above scheme, several detection plates 301 located on the clamping plate 7 are distributed in a vertical array, and the clamping roller 302 on each detection plate 301 is provided with a rough surface for increasing the friction between the clamping roller 302 and the tire and improving the stability of clamping the tire. The distance between the middle parts of two vertically adjacent detection plates 301 is equal to the thickness of the tire, and the first elastic element 303 is a spring for driving the adjacent detection plates 301 to reset.

[0028] Specifically, Figure 2-Figure 4 As shown, the pushing assembly includes: a fixed main cylinder 304, which has two and is fixedly connected to the adjacent clamping plates 7 respectively; a fixed sub-cylinder 305, which is the same in number as the detection plate 301 and is fixedly connected to the adjacent clamping plate 7, and the detection plate 301 is sealed and slidably connected to the adjacent fixed sub-cylinder 305, and several fixed sub-cylinders 305 located on the same clamping plate 7 are fixedly connected and communicated with the adjacent fixed main cylinder 304, and all the detection plates 301, all the fixed sub-cylinders 305 and the fixed main cylinder 304 located on the same clamping plate 7 cooperate to form a closed cavity 3051; an elastic telescopic rod 306, which is fixedly connected to the fixed plate 2, and a flexible tube 307 is fixedly connected between the two fixed main cylinders 304 and the fixed part of the elastic telescopic rod 306, and the two closed cavities 3051 are respectively communicated with the fixed part of the elastic telescopic rod 306 through the adjacent flexible tubes 307; a transmission assembly, which is arranged on the fixed plate 2, and is used to apply a force to the force elimination shaft 8.

[0029] In the above scheme, the two closed cavities 3051 are filled with hydraulic oil. In the initial state, the detection plate 301 is in contact with the side of the adjacent fixed sub-tube 305 away from the adjacent fixed main tube 304. The fixed part of the elastic telescopic rod 306 and the two flexible tubes 307 are filled with hydraulic oil. The flexible tubes 307 have a certain length margin to adapt to the position change of the clamping plate 7, facilitate spatial arrangement, and avoid entanglement. By automatically detecting the number of tires clamped by the two clamping plates 7, the force acting on the force-eliminating shaft 8 is automatically adjusted, thereby maintaining the force balance at the connection between the fixed plate 2 and the sliding plate 5 and at the connection between the clamping plate 7 and the sliding plate 5, thereby reducing the probability of the sliding plate 5 and the two clamping plates 7 getting stuck.

[0030] Specifically, Figure 2 and Figure 5 As shown, the transmission assembly includes: a fixed frame 401, fixedly connected to the fixed plate 2; a telescopic plate 402, rotatably connected to the fixed frame 401, the telescopic end of the telescopic plate 402 is hinged to the telescopic end of the elastic telescopic rod 306; a position adaptation assembly, arranged on the fixed frame 401, for adapting to changes in the position of the sliding plate 5.

[0031] In the above scheme, there are two fixed frames 401 and two telescopic plates 402, which are located on both sides of the fixed plate 2. The telescopic plate 402 is made of high-strength steel and has a certain structural strength to extend its service life. The elastic telescopic rod 306 is located in the middle of the fixed plate 2, and the telescopic ends of the two telescopic plates 402 are hinged to the telescopic ends of the elastic telescopic rod 306, which are used to pull the two ends of the force dissipation shaft 8 to evenly distribute the pulling force.

[0032] Specifically, Figure 2 and Figure 5As shown, the position adaptation component includes: a sliding frame 403, which is slidably connected to the fixed frame 401, and the sliding frame 403 is in contact with the side of the telescopic plate 402 away from the elastic telescopic rod 306; a connecting block 404, which is limitedly slidably connected to the sliding frame 403; a partition component, which is arranged on the fixed plate 2 and is used to isolate the force acting on the force elimination axis 8; the distance from the connection between the telescopic plate 402 and the fixed frame 401 to the telescopic end of the elastic telescopic rod 306 is greater than the distance from the connection between the telescopic plate 402 and the fixed frame 401 to the sliding frame 403.

[0033] In the above scheme, there are two sliding frames 403 and two connecting blocks 404. The sliding frame 403 slides back and forth along the fixed frame 401. The top of the sliding frame 403 is in contact with the side of the telescopic plate 402 away from the elastic telescopic rod 306, and the contacting side of the telescopic plate 402 and the sliding frame 403 has a sufficient contact length. The connecting block 404 is vertically slidably connected to the sliding frame 403 to adapt to the change of the position of the sliding plate 5. The distance from the connection between the telescopic plate 402 and the fixed frame 401 to the telescopic end of the elastic telescopic rod 306 is greater than the distance from the connection between the telescopic plate 402 and the fixed frame 401 to the sliding frame 403, which is used to enable the telescopic plate 402 to drive the sliding frame 403 to move with the help of the lever principle, thereby reducing the force of the clamping roller 302 on the tire and avoiding deformation of the tire due to excessive force.

[0034] Specifically, Figure 2 , Figure 5 and Figure 6 As shown, the partition assembly includes: an electric push rod 501, fixedly connected to the fixed plate 2; a trigger frame 502, fixedly connected to the telescopic end of the electric push rod 501; a force plate 503, limitedly slidably connected to the force dissipation shaft 8, a second elastic element 504 is arranged between the force plate 503 and the connecting block 404, and the trigger frame 502 limits the force plate 503.

[0035] In the above scheme, the electric push rod 501 is electrically connected to the control system, and the trigger frame 502 is a U-shaped frame, which is used to extend the fitting length of the force plate 503 and the trigger frame 502 to adapt to the change of the position of the force plate 503. The trigger frame 502 pushes the force plate 503 to slide along the force axis 8, so that a certain gap is left between the force plate 503 and the force dissipation axis 8, thereby completely cutting off the force of the second elastic element 504. The second elastic element 504 is a tension spring, which is used to quickly pull the force plate 503 to slide along the force dissipation axis 8 until the force plate 503 is limited by the force dissipation axis 8 and cannot continue to slide. At this time, the force of the second elastic element 504 is transmitted to the force dissipation axis 8 through the force plate 503, and when the tire moves upward, the force that was cut off in advance is instantly applied to the force dissipation axis 8, so that the force at the connection between the fixed plate 2, the sliding plate 5, and the clamping plate 7 is balanced, thereby reducing the probability of the sliding plate 5 and the two clamping plates 7 being stuck.

[0036] When the tires need to be stacked, the robot arm grabs the tires to be stacked and places them on the conveying device of the conveying base 1. Then the staff turns on the conveying device of the conveying base 1, and the conveying device of the conveying base 1 drives the tires to be transported from the back to the front, and conveys the tires to the stacking position at the fixed plate 2. In this way, when the tires run to the stacking position, the conveying device of the conveying base 1 is closed, and the correction position on the conveying base 1 corrects the tires to prevent the tires from being skewed. Then the first motor 3 is turned on, so that the output shaft of the first motor 3 drives the spur gear 4 to rotate, and the spur gear 4 drives the sliding plate 5 to move downward to the clamping position of the tire through the rack rack 6. Then the first motor 3 is turned off, and the second motor 201 is turned on, so that the output shaft of the second motor 201 drives the screw 202 to rotate, and the screw 202 drives the two clamping plates 7 to move in opposite directions to clamp the tire, until the clamping plate 7 drives the lowermost clamping roller 302 to contact the tire.

[0037] When the clamping roller 302 at the lowermost side of the clamping plate 7 contacts the tire, the two clamping plates 7 continue to move toward each other, and the tire will squeeze the four adjacent clamping rollers 302. The clamping rollers 302 are squeezed by the squeezing force to drive the adjacent detection plate 301 to slide along the adjacent fixed sub-cylinder 305, and push the hydraulic oil inside the closed cavity 3051 along the adjacent flexible tube 307 into the fixed part of the elastic telescopic rod 306. At the same time, the first elastic element 303 is compressed, and the hydraulic oil in the fixed part of the elastic telescopic rod 306 pushes its telescopic end to extend outward. The telescopic end of the elastic telescopic rod 306 drives the telescopic ends of the two telescopic plates 402 to move synchronously, and the telescopic plates 402 rotate along the fixed frame 401, so that the telescopic plates 402 are away from One side of the elastic telescopic rod 306 pushes the sliding frame 403 to slide along the fixed frame 401, and the sliding frame 403 drives the connecting block 404 thereon to move synchronously, and the second elastic element 504 is stretched, and the stretching force of the second elastic element 504 acts on the force plate 503. At this time, since the tire is still placed on the conveying base 1, the force of the force plate 503 acts on the trigger frame 502, and the stretching force of the second elastic element 504 cannot temporarily act on the force dissipation shaft 8 through the force plate 503, thereby offsetting the force when driving the tire to move upward, and this is done until the first elastic element 303 is compressed to the limit state, the second motor 201 is turned off, and the opposite movement of the two clamping plates 7 is stopped, that is, the tire clamping is completed.

[0038] After the tire is clamped, the first motor 3 is turned on, so that the output shaft of the first motor 3 drives the sliding plate 5 to move upward to a specific height (this height is greater than the height of the tire, so that the tire can be transported to the stacking position by the conveying device of the conveying base 1 later), and then the first motor 3 is turned off. During this process, the tire is separated from the conveying base 1, and the gravity of the tire instantly acts on the connection between the fixed plate 2 and the sliding plate 5 and the connection between the clamping plate 7 and the sliding plate 5 through the two clamping plates 7. Therefore, when the first motor 3 is turned on, the electric push rod 501 is turned on synchronously, and the telescopic end of the electric push rod 501 drives the trigger frame 50 2 moves backward, the trigger frame 502 is separated from the two force-applying plates 503, and the pulling force of the second elastic element 504 drives the adjacent force-applying plates 503 to slide along the force-dissipating shaft 8 and contact each other. Then, the tensile force of the second elastic element 504 instantly acts on the force-dissipating shaft 8 through the force-applying plates 503, counteracting the force of the tire's own gravity on the connection between the fixed plate 2 and the sliding plate 5 and the connection between the clamping plate 7 and the sliding plate 5, reducing the stress concentration at the connection between the fixed plate 2 and the sliding plate 5 and the connection between the clamping plate 7 and the sliding plate 5, avoiding deformation caused by long-term stress concentration, resulting in the sliding plate 5 and the two clamping plates 7 being stuck.

[0039] When the two clamping plates 7 drive the tire to a specific height, the conveying device of the conveying base 1 is turned on to drive the next tire to the stacking position, and then the conveying device of the conveying base 1 is closed. At this time, the first motor 3 is turned on, so that the output shaft of the first motor 3 drives the sliding plate 5 to move downward through the spur gear 4 and the rack frame 6, and the sliding plate 5 drives the clamped tire to move downward synchronously through the two clamping plates 7, so that the lower side of the clamped tire is in contact with the upper side of the tire on the conveying base 1, and then the electric push rod 501 is turned on, so that the telescopic end of the electric push rod 501 drives the trigger frame 502 to contact with the two force plates 503, thereby cutting off the tensile force of the second elastic element 504, and the first motor 3 is turned off, and the second motor 201 is turned on, so that the output shaft of the second motor 201 drives the two clamping plates 7 to move backward through the screw 202, thereby releasing the clamping of the tire, that is, placing the clamped tire on the upper side of the tire on the conveying base 1. At this time, the second elastic element 504 The reset drives the adjacent fixing frame 401 to reset through the connecting block 404, and the fixing frame 401 drives the adjacent telescopic plate 402 to reset. At the same time, the hydraulic oil in the fixing part of the elastic telescopic rod 306 flows back to the two closed cavities 3051, and at the same time, the first elastic element 303 drives the adjacent detection plate 301 to reset, and then repeats the above-mentioned clamping steps of the tire. At this time, the clamping plate 7 clamps two tires, that is, the extension distance of the telescopic end of the elastic telescopic rod 306 increases (the specific transmission steps are the same as the above steps), that is, the rotation amplitude of the telescopic plate 402 increases, so that the stretching amplitude of the second elastic element 504 increases synchronously, thereby increasing the force of the second elastic element 504 on the force dissipation shaft 8, and automatically detecting the clamping amount of the two clamping plates 7 on the tires, automatically adjusting the force on the force dissipation shaft 8, thereby maintaining the force balance at the connection between the fixed plate 2 and the sliding plate 5 and at the connection between the clamping plate 7 and the sliding plate 5, thereby reducing the probability of the sliding plate 5 and the two clamping plates 7 being stuck.

[0040] Repeat the above steps to stack the tires until the required number of tires are stacked. At this time, the conveying device of the conveying base 1 is turned on to convey and store the stacked tires. Then repeat the above steps to continue stacking the tires until the tire stacking work is completed.

[0041] In this embodiment, the connection relationship between the output shaft of the first motor 3 and the spur gear 4 is a fixed connection, and the connection relationship between the output shaft of the second motor 201 and the screw 202 is also a fixed connection, but this is limited to this embodiment. In other subsequent embodiments, the connection relationship between the output shaft of the first motor 3 and the spur gear 4 is a rotational connection, and the connection relationship between the output shaft of the second motor 201 and the screw 202 is also a rotational connection. Please refer to the specific description in the subsequent embodiments.

[0042] In a further embodiment, Figure 7-Figure 9As shown, it also includes: a cutting component, which is arranged on the output shaft of the first motor 3 and the output shaft of the second motor 201, and is used to make the output shafts of the first motor 3 and the second motor 201 idle, and the cutting component includes: a clamping block 601, which has two, and is respectively fixedly connected to the output shaft of the first motor 3 and the output shaft of the second motor 201, the output shaft of the first motor 3 is rotationally connected to the spur gear 4, and the output shaft of the second motor 201 is rotationally connected to the lead screw 202; a limit block 602, which has two, is respectively slidably connected to the spur gear 4 and the lead screw 202, and the clamping block 601 is used to squeeze the adjacent limit block 602; a connecting frame 603, which has two, is respectively fixedly connected to the spur gear 4 and the lead screw 202, the limit block 602 is slidably connected to the adjacent connecting frame 603, and a third elastic element 604 is arranged between the limit block 602 and the adjacent connecting frame 603; a locking component, which has two, is respectively arranged on the two connecting frames 603, and is used to lock the limit block 602.

[0043] In the above scheme, the clamping block 601 has two symmetrically distributed inclined surfaces, and the limit block 602 has two symmetrically distributed inclined surfaces. The inclined surface on the clamping block 601 fits with the adjacent inclined surface on the adjacent limit block 602. When the device is stuck, the output shaft of the first motor 3 or the output shaft of the second motor 201 drives the inclined surface of the clamping block 601 to squeeze the inclined surface of the limit block 602, so that the limit block 602 slides along the connecting frame 603. The third elastic element 604 is a rubber ring, and the compression force of the third elastic element 604 is greater than the sum of the gravity of the sliding plate 5 and the parts thereon and the gravity of the set number of tires clamped, so that the output shaft of the first motor 3 drives the sliding plate 5 to move when it is not stuck, and at the same time, the output shaft of the second motor 201 can drive the two clamping plates 7 to move in opposite or opposite directions when it is not stuck.

[0044] Specifically, Figure 7-Figure 9 As shown, the locking assembly includes: a limit plug shaft 605, which is slidably connected to the adjacent connecting frame 603; a fourth elastic element 606, which is arranged between the adjacent limit plug shaft 605 and the adjacent connecting frame 603, and the limit block 602 is provided with a docking hole 607, and the limit plug shaft 605 is used to lock the limit block 602 through the docking hole 607, and the limit block 602 limits the adjacent limit plug shaft 605; an infrared sensor 608, which is fixedly connected to the connecting frame 603 and is used to detect the state of the adjacent limit block 602.

[0045] In the above scheme, the limit plug shaft 605 is a high shear force pin shaft, which is used to resist the reset force of the adjacent third elastic element 604. The fourth elastic element 606 is a spring, and the initial state is a compressed state, which is used to drive the limit plug shaft 605 into the docking hole 607 of the limit block 602. The infrared sensor 608 is electrically connected to the control system to detect whether the limit block 602 slides. When the sliding plate 5 or the clamping plate 7 is stuck, the transmission of the output shaft of the first motor 3 or the output shaft of the second motor 201 is cut off. At the same time, the device is shut down and an alarm signal is released to the staff to avoid damage to the output shaft of the first motor 3 and the second motor 201 due to increased load and increased temperature.

[0046] After the device is used for a long time, it is very easy to cause the slide rail of the device to be deformed due to stress concentration, which in turn causes the sliding plate 5 or the two clamping plates 7 to become stuck. The stuck state of the sliding plate 5 is used as an example. At this time, the sliding plate 5 cannot slide up and down along the fixed plate 2, that is, the spur gear 4 cannot rotate along the fixed plate 2. Since the output shaft of the first motor 3 is still in a rotating state, the output shaft of the first motor 3 drives the clamping block 601 to squeeze the adjacent limit block 602, so that the limit block 602 slides along the spur gear 4. At the same time, the third elastic element 604 is compressed and deformed, and this continues until the limit block 602 is separated from the adjacent clamping block 601. At this time, the output shaft of the first motor 3 is switched from a loaded state to a no-load state, so as to avoid the output shaft of the first motor 3 being unable to rotate after the sliding plate 5 is stuck, causing the first motor 3 to heat up rapidly and be damaged.

[0047] When the limit block 602 slides along the spur gear 4, the limit block 602 drives the docking hole 607 thereon to move synchronously. When the clamping block 601 separates from the limit block 602, the central axis of the docking hole 607 coincides with the central axis of the limit plug shaft 605. At this time, the fourth elastic element 606 drives the limit plug shaft 605 to enter the docking hole 607 of the adjacent limit block 602, so that the limit plug shaft 605 locks the limit block 602 through the docking hole 607, avoiding the limit block 602 from resetting and blocking the clamping block 601, causing the output shaft of the first motor 3 to get stuck again and heating up. At the same time, after the limit block 602 is locked along the connecting frame 603, the infrared sensor 608 detects the appearance of the limit block 602, and then sends a signal to the control system to shut down the device, and at the same time sends an alarm signal to enable the staff to perform maintenance.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
