Description

[0001] The invention belongs to the technical field of tire palletizing, and in particular relates to a vertical automatic tire palletizing device. Background Art

[0002] In the process of tire assembly and production, in order to save the space occupied by automobile tires, automobile tires are generally stacked in stacks to fully utilize the production space and achieve the purpose of rapid transportation and transshipment. However, based on the existing technology, it is found that in the existing tire stacking equipment, the mechanical claws will clamp the tires from the outside when grabbing the tires, which results in the mechanical claws needing to use a large clamping force to clamp the tires in the process of clamping the tires, and then transfer the tires, which can easily cause the tires to be deformed by large pressure. In addition, in the process of stacking tires, when the mechanical claws release the tires, the tires will rebound and catapulted to another adjacent tire that has been stacked, which can cause the entire stacked set of tires to shake easily, resulting in an increased risk of collapse of the stacked tires.

[0003] Moreover, when the stacked tires are transported, the necessary protective measures are lacking, which may easily lead to the center of gravity of the entire set of tires being unstable during the transport, further increasing the risk of collapse. Summary of the Invention

[0015] The advantages and positive effects of the present invention are:

[0016] (1) By moving all the swinging rods to the position just above the tire and aligning the center of the connecting rod with the center of the tire, the swinging rods are driven to move to the inside of the tire, and the two first electric actuators are controlled to start and drive the sliding blocks to move upward. The sliding blocks move through the corresponding oblique rods to drive the corresponding swinging rods to move, thereby causing all the swinging rods to expand outward, and then drive the connected fixed blocks, rotating shafts, fixed rods, elastic parts and top rods to expand outward, and then the four top rods are moved upward to press against the inner top of the tire, thereby supporting and limiting the tire from the inner top of the tire through the four top rods, thereby avoiding squeezing the tire and causing the tire to deform. Then the tire is moved to the specified position and the tires are continuously stacked upward, thereby realizing automatic stacking of the tires.

[0017] (2) The corresponding limiting rollers are moved and pressed against the outer side of the lowest tire, thereby limiting the tire through the corresponding limiting rollers, and the outer diameter of the tire and the placement position of the tire can be known through the corresponding limiting rollers. At this time, the position of the corresponding limiting rollers remains unchanged, thereby facilitating the limiting and positioning of the subsequent stacked tires.

[0018] (3) The corresponding limiting rollers squeeze the upper tire, forcing the upper tire to remain flush with the bottom tire, so that the entire stack of tires remains flush, reducing the risk of collapse.

[0019] (4) The corresponding limiting rollers are used to keep the tires stable as they are stacked upwards. As more and more tires are stacked upwards, the corresponding limiting rollers are used to gradually move upwards until all tires are limited in turn, so that all tires remain level.

[0020] (5) The inner top of the bottom tire is supported and limited by four push rods, and the two tires at the top are pressurized by the corresponding limiting rollers, thereby increasing the friction between the corresponding limiting rollers and the two tires at the top, and then driving the corresponding limiting rollers to move downward, so that the two tires at the top can jointly pressurize the remaining tires, and the bottom tire has been supported and limited by the four push rods, so that all the tires that have been stacked can form a whole before being transferred, thereby avoiding the problem of skewing and collapse of all the tires that have been stacked during the transfer process.

[0034] An image recognition device is installed at the lower part of the fixing plate 204 for photographing and identifying the placement position of the tire 6 and identifying the information on the tire 6 .

[0035] The limiting mechanism includes a fixed block 209, a rotating shaft 210, a fixed rod 211, an elastic member 212 and a top rod 213; the upper part of the swing rod 208 is fixedly connected to the fixed block 209; the rotating shaft 210 is rotatably connected to the fixed block 209; the rotating shaft 210 is rotatably connected to the fixed rod 211; two elastic members 212 are connected between the fixed rod 211 and the rotating shaft 210, and the elastic member 212 is a torsion spring, and one end of the elastic member 212 is fixedly connected to the fixed block 209, and one end of the elastic member 212 is fixedly connected to the fixed rod 211; the upper part of the fixed rod 211 is fixedly connected to the top rod 213.

[0036] A rubber strip is provided on the upper surface of the push rod 213 to increase the friction between the push rod 213 and the tire 6 and prevent the push rod 213 from scratching the tire 6.

[0037] The driving mechanism includes a second electric slide rail 1, a second electric slider 2, a third electric slide rail 3 and a third electric slider 4; two second electric slide rails 1 are provided, and each second electric slide rail 1 is slidably connected to a second electric slider 2; a third electric slide rail 3 is fixedly connected to the two second electric sliders 2; two third electric sliders 4 are slidably connected to the third electric slide rail 3; the two third electric sliders 4 are both fixedly connected to the support frame 5.

[0038] When the present vertical tire automatic stacking equipment is in use, the image recognition device installed at the lower part of the fixed plate 204 is used to identify the tire 6 in the area, thereby determining the position of the tire 6, and then controlling the two second electric sliders 2 to start and move along a second electric slide rail 1 according to the position of the tire 6, and the movement of the two second electric sliders 2 drives the third electric slide rail 3 to move, thereby driving all the connected components to move, and then controlling the two third electric sliders 4 to start and move along the third electric slide rail 3, and the movement of the two third electric sliders 4 drives the support frame 5 to move, and the movement of the support frame 5 drives all the connected components to move, thereby driving all the swing rods 208 to move, so that all the swing rods 208 move to the position just above the tire 6, and the center of the connecting rod 205 is aligned with the center of the tire 6, and then controlling the two second electric actuators 202 to start and drive each fixing ring 203 to move downward, and the movement of the two fixing rings 203 drives the fixing plate 204 to move, and the movement of the fixing plate 204 drives the connecting rod 205 to move, thereby driving all the connected components to move, thereby driving all the swing rods 208 to move to the inner side of the tire 6, as shown in FIG. Figure 5As shown, the two first electric actuators 207 are controlled to start and drive the sliding blocks 2071 to move downward. The sliding blocks 2071 move through the corresponding oblique rods 2072 to drive the corresponding swing rods 208 to move, thereby causing all the swing rods 208 to expand outward, thereby driving the connected fixed blocks 209, the rotating shaft 210, the fixed rod 211, the elastic member 212 and the top rod 213 to expand outward, and causing the top rod 213 to move close to the inner side wall of the tire 6, thereby making the distance between the two left and right opposite top rods 213 and the distance between the two front and rear opposite top rods 213 based on the front side of the support frame 5 greater than the diameter of the upper opening of the tire 6, so that the four top rods 213 can support and limit the tire 6 from the inner top of the tire 6; after the four top rods 213 are all expanded outward, the two second electric actuators 202 are controlled to start each driving A fixing ring 203 moves upward, and the movement of the two fixing rings 203 drives the fixing plate 204 to move, and the movement of the fixing plate 204 drives the connecting rod 205 to move, thereby driving all connected parts to move, and then driving the four top rods 213 to move, and making the four top rods 213 move upward to press against the inner top of the tire 6. At this time, the four top rods 213 all rotate, thereby driving the corresponding fixing rods 211 to rotate, and then twisting the four elastic members 212, so that the tire 6 is supported and limited from the inner top of the tire 6 by the four top rods 213, thereby avoiding squeezing the tire 6 and causing the tire 6 to deform. Then, the two second electric actuators 202 are controlled to start in the same way as above, and then the two second electric sliders 2 are controlled to start, and the two third electric sliders 4 are controlled to start, so as to move the tire 6 to the specified position.

[0039] After the tire 6 is moved to the specified position, the four push rods 213 are separated from the inner top of the tire 6, and the two second electric actuators 202 are controlled to start and each drive a fixing ring 203 to move downward. The movement of the two fixing rings 203 drives the fixing plate 204 to move, and the movement of the fixing plate 204 drives the connecting rod 205 to move, thereby driving all connected components to move, thereby driving the four push rods 213 to move downward and separate from the inner top of the tire 6. Then, the two first electric actuators 207 are controlled to start and drive the sliding blocks 2071 to move upward. The sliding blocks 2071 move through the corresponding oblique rods 2072 to drive the corresponding swing rods 208 to move, thereby causing all the swing rods 208 to retract inward, thereby driving the connected fixing blocks 209, rotating shafts 210, fixing rods 211, elastic members 212 and push rods 213 to retract inward and reset. Then, in the same manner as above, the two second electric actuators 202 are controlled to start and each drive a fixing ring 203 to move upward, thereby causing all the swing rods 208 to move upward and separate from the tire 6.

[0040] When palletizing, all the swing rods 208 are moved in the same manner as above, and then the four top rods 213 are used to support and limit another tire 6, and then the other tire 6 is driven to move until the two tires 6 are stacked and palletized. Figure 5 As shown, when multiple tires 6 need to be stacked, the tires 6 are continuously stacked upward in the same manner, thereby achieving automatic stacking of the tires 6 .

[0041] Example 2:

[0042] On the basis of Example 1, according to Figure 1 and Figure 6-Figure 7 As shown, it also includes a stacking system; the stacking system is connected to the support frame 5; the stacking system includes a fourth electric slide rail 301, a fourth electric slider 302, a third electric actuator 303, a curved rod 304, a sleeve 305 and a limiting roller 306; two fourth electric slide rails 301 are fixedly connected to the support frame 5; each fourth electric slide rail 301 is slidably connected to a fourth electric slider 302; each fourth electric slider 302 is fixedly connected to a third electric actuator 303, the third electric actuator 303 is an electric push rod, and each telescopic part of the third electric actuator 303 is fixedly connected to a curved rod 304; each curved rod 304 is fixedly connected to two sleeves 305; each sleeve 305 is rotatably connected to a limiting roller 306.

[0043] A pressure sensor is provided at the connection between the third electric actuator 303 and the arc-shaped rod 304 for detecting the pressure exerted on the limiting roller 306 when limiting the tire 6 .

[0044] The upper end and the lower end of the limiting roller 306 are both provided with a hemispherical bump for preventing the tire 6 from being scratched.

[0045] The outer surface of the limiting roller 306 is made of smooth stainless steel to prevent the tire 6 from being scratched.

[0046] It also includes a first electric slide rail 51 and a first electric slider 52 ; the first electric slide rail 51 is fixedly connected to the support frame 5 ; the first electric slider 52 is slidably connected to the first electric slide rail 51 ; the first electric slider 52 is fixedly connected to the mounting plate 201 .

[0047] In the process of continuously stacking tires 6, the overall height of the stacked tires 6 will continue to increase, thereby making the center of gravity of the tires 6 stacked on top unstable. If the tires 6 are continuously stacked upward, it is easy to cause all the stacked tires 6 to collapse, thereby affecting the normal stacking process. In order to solve the above problem, when two tires 6 are stacked, the two fourth electric sliders 302 are controlled to start and move downward along a fourth electric slide rail 301. The movement of the two fourth electric sliders 302 each drives a third electric actuator 303 to move. The movement of the two third electric actuators 303 drives all the connected components to move, thereby making the corresponding limit The rollers 306 all move downward and are located on the outside of the lowest tire 6. Then, the two third electric actuators 303 are controlled to start and each drives an arc rod 304 to move. The two arc rods 304 move the corresponding sleeves 305 and the corresponding limiting rollers 306 until the corresponding limiting rollers 306 all press against the outside of the lowest tire 6. Thus, the tire 6 is limited by the corresponding limiting rollers 306, and the outer diameter of the tire 6 and the placement position of the tire 6 can be known through the corresponding limiting rollers 306. At this time, the position of the corresponding limiting rollers 306 remains unchanged, which facilitates the limiting and correcting of the tires 6 to be stacked subsequently.

[0048] Then, the two fourth electric sliders 302 are controlled to start and move upward along a fourth electric slide rail 301 respectively. The movement of the two fourth electric sliders 302 drives all the connected parts to move, and then drives the corresponding limiting rollers 306 to move upward. Since the corresponding limiting rollers 306 have limited the bottom tire 6, and the position of the corresponding limiting rollers 306 remains unchanged, the corresponding limiting rollers 306 can limit the tire 6 located above when moving upward. If the tire 6 located above is not aligned with the tire 6 located below, the corresponding limiting rollers 306 can squeeze the tire 6 located above, thereby forcing the tire 6 located above to remain flush with the tire 6 located below. Figure 7 As shown, the stacked tires 6 are kept flat as a whole, reducing the risk of collapse;

[0049] When the tires 6 are continuously stacked upward, the position of the corresponding limiting roller 306 remains unchanged and is located between the two tires 6 that have been stacked. Figure 7As shown, the swing arm 208 has separated from the tire 6 located above, and then the first electric slider 52 is controlled to start moving along the first electric slide rail 51. The movement of the first electric slider 52 drives the installation plate 201 to move. The movement of the installation plate 201 drives the two second electric actuators 202 to move. The movement of the two second electric actuators 202 drives all connected components to move, thereby driving all the swing arms 208 and all connected components to move. Then, the four top rods 213 are used to limit the positions of the remaining tires 6 in sequence, and the tires 6 are stacked and stacked in sequence. Since the two tires 6 located at the bottom are limited by the corresponding limiting rollers 306, the stacked tires 6 can be kept stable as the tires 6 are continuously stacked upward. As more and more tires 6 are stacked upward, the two fourth electric sliders 302 are controlled in the same manner as above to start moving upward along a fourth electric slide rail 301, thereby causing the corresponding limiting rollers 306 to move upward step by step until all the tires 6 are limited in sequence, thereby keeping all the tires 6 flush.

[0050] It should be noted that the prior art uses a mechanical claw to clamp the tire 6 from the outside of the tire 6, which results in the mechanical claw needing to use a larger clamping force to clamp the tire 6 during the process of clamping the tire 6, and then transfer the tire 6. However, this device uses a connecting rod 205 to bear the gravity of the tire 6, and then limits the tire 6 through a limiting roller 306 to prevent the tire 6 from tilting during transfer, thereby avoiding deformation of the tire 6 that affects its quality.

[0051] After stacking multiple tires 6, all the stacked tires 6 are transferred at once. At this time, all the swing arms 208 are moved to the inner side of the lowest tire 6 in the same way as above, and the four top rods 213 are pressed against the inner top of the lowest tire 6, so as to support and limit the lowest tire 6. At the same time, the corresponding limiting rollers 306 move upward step by step until all the tires 6 are limited in turn, so that the corresponding limiting rollers 306 are located between the two uppermost tires 6 and limit the two uppermost tires 6. Then, the two third electric actuators 303 are controlled to start and each drive an arc rod 304 to move, so that the two arc rods 304 move toward each other, thereby The corresponding limiting rollers 306 move toward each other to apply pressure to the two tires 6 at the top, thereby increasing the friction between the corresponding limiting rollers 306 and the two tires 6 at the top, and then control the two fourth electric sliders 302 to start and move downward along a fourth electric slide rail 301, thereby driving the corresponding limiting rollers 306 to move downward, so that the two tires 6 at the top jointly apply pressure to the remaining tires 6, and the tire 6 at the bottom has been supported and limited by the four top rods 213, so that all the tires 6 that have been stacked form a whole before being transferred, thereby avoiding the problem of skewing and collapse of all the tires 6 that have been stacked during the transfer process, thereby completing the stacking and transfer operations of all the tires 6.
