Description

Technical Field

[0001] The invention relates to the field of tire manufacturing, in particular to a tire blank automatic unloading, tire retreading and centering conveying device for a tire building machine. Background Art

[0002] When the secondary tire building machine is in use, the formed tire blank is placed on the building drum in an upright state (the axis is set in the horizontal direction). After the forming is completed, the tire blank needs to be taken out from the building drum and put into the subsequent logistics line for subsequent processing. It is worth noting that when the tire blank is transported in the logistics line, it is transported in a flat state (the axis is set in the vertical direction), because this can prevent the tire blank from moving, so as to facilitate the subsequent use of the tire blank. That is, after the tire blank is formed, the tire blank needs to be taken out from the building drum and put into the logistics line, and the tire blank needs to be turned over at the same time.

[0003] In order to achieve the above-mentioned purpose of tire unloading, there are usually the following two methods in the prior art: First, after the tire embryo is formed, the transfer ring moves to the center position of the tire embryo and clamps the tire embryo, then the transfer ring moves axially outward to the tire unloading position, the transfer ring releases the tire embryo, and the tire embryo is manually taken out. Second, after the tire embryo is formed, the transfer ring moves to the center position of the tire embryo and clamps the tire embryo, then the transfer ring moves axially outward to the end of the forming drum, the transfer ring releases the tire embryo, the tire embryo falls on the end of the forming drum, and the tire embryo is manually taken out from the end of the forming drum and put into the tire unloading position.

[0004] That is to say, there is no corresponding tire unloading device that can directly put the tire blank from the forming drum into the tire unloading position, and the tire unloading action relies on manual work.

[0005] In order to achieve the above-mentioned purpose of tire flipping, the Chinese utility model patent (publication number: CN215556808U, publication date: 2022.01.18) discloses an automatic tire blank forming flipping and conveying system, including a horizontal bracket, a vertical bracket, a lifting cylinder and a flipping cylinder. When in use, the tire blank is placed on the horizontal bracket and the vertical bracket, and the horizontal bracket and the vertical bracket are driven to flip by the flipping cylinder to realize the flipping of the tire blank.

[0006] Although the above-mentioned conveying system realizes the turning of the tire blank, the turning structure is relatively complicated and needs to be controlled by the cooperation of the lifting cylinder and the turning cylinder, and the tire blank is easy to separate from the horizontal support and the vertical support during the turning process. In addition, the above-mentioned conveying system is not equipped with a device for unloading the tire, and manual operation is required, which reduces production efficiency and increases the labor intensity of workers. Summary of the invention

[0030] The secondary tire building machine (not shown) includes a first-stage building machine and a second-stage building machine. The first-stage building machine has a transversely arranged metal drum, and the second-stage building machine has a transversely arranged belt drum (also called tread drum). A transfer ring 500 coaxial with the belt drum and movable in the axial direction is arranged on one side of the belt drum. Usually, the transfer ring 500 is an annular component, and the bottom of the transfer ring 500 is slidably arranged on the slide rail 600 so that it can move in the axial direction. A plurality of clamping plates that can move in the radial direction are arranged inside the transfer ring 500, and these clamping plates are evenly arranged in the circumferential direction.

[0031] When the secondary tire forming machine is used, the inner liner, carcass layer, bead cover, tire bead and other materials are sequentially bonded on the metal drum, and these materials are compounded to form a carcass assembly. Multiple belt layers and a tread layer are sequentially bonded on the belt drum, and these materials are compounded to form a crown assembly. The transfer ring 500 takes the crown assembly out of the belt drum, and then the carcass assembly is manually taken out of the metal drum and put into the belt drum. Then the transfer ring 500 moves the crown assembly back to the belt drum, and then the belt drum inflates the carcass assembly, and the carcass assembly expands outward and finally contacts the inner surface of the crown assembly. At this time, the transfer ring 500 releases the crown assembly, and the transfer ring 500 moves axially outward away from the belt drum, and the crown assembly is connected to the carcass assembly. Finally, the crown assembly is compounded on the carcass assembly by rolling, and a tire embryo is formed after the compounding is completed.

[0032] In the prior art, there are usually two methods for removing the formed tire blank from the belt drum:

[0033] First, after the tire blank is formed, it remains on the belt drum, the transfer ring 500 moves to the center of the tire blank and clamps the tire blank, then the transfer ring 500 moves axially outward to the tire unloading position, the transfer ring 500 releases the tire blank, and the tire blank is manually taken out.

[0034] Secondly, after the tire blank is formed, it remains on the belt drum, the transfer ring 500 moves to the center of the tire blank and clamps the tire blank, then the transfer ring 500 moves axially outward to the end of the belt drum, the transfer ring 500 releases the tire blank, and the tire blank falls on the end of the belt drum, and is manually taken out from the end of the belt drum and put into the tire unloading position.

[0035] Both of the above methods require manual placement of the tire blank into the tire unloading position, which has a low degree of automation, and the additional manual operation reduces production efficiency. In addition, it is noted that the tire blank after molding is in an upright state (the axial direction is arranged in the horizontal direction), which is prone to rolling, which is not conducive to the subsequent transportation of the tire blank. Therefore, during the tire unloading process, the tire blank needs to be turned over to a flat state (the axial direction is arranged in the vertical direction). In order to solve the above problems, the present invention provides a tire blank automatic unloading, tire folding, centering and conveying device for a tire forming machine, which realizes automatic tire unloading, tire folding, centering and conveying without manual intervention, thereby improving production efficiency.

[0036] Figure 1 A stereoscopic view of a tire unloading, tire folding and centering conveying device for a tire forming machine is shown. The device is arranged on one side of the belt drum axial direction. The device includes: a tire unloading device 100, a guide channel 200, a tire folding device 300 and a centering conveying device 400. The tire unloading device 100 is slidably arranged on a slide rail 600 and moves back and forth between a tire unloading station and a tire unloading station. In a preferred embodiment, the tire unloading device 100 can be fixedly arranged on one side of a transfer ring 500 and moved synchronously with the transfer ring 500, so that the control system of the transfer ring 500 can be used to control the movement of the tire unloading device 100. The guide channel 200 is arranged on one side of the slide rail 600, and the entrance 201 of the guide channel 200 faces the slide rail 600. In addition, the guide channel 200 is usually arranged to be inclined downward ( Figure 1 The tire blank is embodied as being higher on the left and lower on the right in the guide channel 200, so that the tire blank can roll in the guide channel 200. The tire turning device 300 is arranged at the exit 202 of the guide channel 200, so that the tire blank enters the tire turning device 300 after rolling out of the guide channel 200, and the tire turning device 300 turns the tire blank over, so that it turns from an upright state to a flat state. The centering conveying device 400 is arranged at the output end of the tire turning device 300, and the turned tire blank enters the centering conveying device 400 from the tire turning device 300, and the centering conveying device 400 centers and conveys the tire blank. In addition, a tire blank elevator (not shown) is usually arranged at the output end of the centering conveying device 400 to receive and transport the tire blank.

[0037] It should be noted that the tire blank clamping station mentioned above refers to the position where the tire blank is formed on the belt drum, that is, the position where the formed tire blank is located. The tire unloading station refers to the position where the entrance 201 of the guide channel 200 is located. In other words, the tire unloading device 100 moves back and forth between the belt drum and the guide channel 200. In addition, the guide channel 200 can be an independent device or component, and can also be formed on the input end of the tire folding device 300 as a part of the tire folding device 300, that is, the guide channel 200 only needs to provide a channel for the tire blank to roll from the tire unloading device 100 to the tire folding device 300. In addition, by reasonably setting the length and inclination angle of the guide channel 200, the position of the tire folding device 300 can also be adjusted to facilitate the layout of the equipment and adapt to the configuration of different factory buildings.

[0038] When the device is used, the tire unloading device 100 moves to the tire blank clamping station, so that it is aligned with the center line of the tire blank on the belt drum, and the tire unloading device 100 clamps the outer peripheral surface of the tire blank, and the belt drum releases the tire blank, so that the tire blank is transferred to the tire unloading device 100. Then the tire unloading device 100 moves to the tire unloading station, so that the tire blank is aligned with the entrance 201 of the guide channel 200, and the tire unloading device 100 pushes the tire blank into the guide channel 200, and the tire blank enters the guide channel 200 in an upright state, and rolls forward along the extension direction of the guide channel 200 until the tire blank enters the tire turning device 300, and the tire turning device 300 stops the rolling tire blank, and then turns the upright tire blank into a flat state, and then the tire turning device 300 sends the tire blank into the centering conveying device 400, and the centering conveying device 400 positions the tire blank and conveys it outward.

[0039] The beneficial effects of the device are as follows: the tire unloading device 100 takes the tire blank from the belt drum and puts it into the guide channel 200, realizing the automatic unloading of the tire blank, avoiding manual processing, and improving the efficiency of tire unloading. The tire turning device 300 turns the tire blank into a flat state, which is convenient for the subsequent transportation of the tire blank. The centering conveying device 400 locates the position of the tire blank to ensure the accuracy of the position of the tire blank when it is output from the centering conveying device 400, so that the tire blank can smoothly enter the subsequent material line, which is convenient for the subsequent taking and placing of the tire blank.

[0040] The specific structure of each device is introduced in turn below.

[0041] like Figure 4 As shown, the tire unloading device 100 includes a base 110 slidably disposed on the slide rail 600. The base 110 may be a separate component, a part of the transfer ring 500, or a connecting plate fixedly disposed with the transfer ring 500. In this embodiment, the tire unloading device 100 is fixedly connected to the transfer ring 500, so it can be considered that the base 110 is disposed on the transfer ring 500. Figure 4It can be seen from the figure that the base 110 is roughly L-shaped. The upper end surface of the base 110 is provided with a first driving component 120 ( Figure 4 The reason for the medium viewing angle is not shown, see Figure 3 ), the output end of the first driving component 120 has a degree of freedom in the up-down direction, that is, the output end of the first driving component 120 can move up and down. The output end of the first driving component 120 is connected to the lifting platform 130, and the first driving component 120 drives the lifting platform 130 to move up and down above the base 110. Commonly, a guide component (such as a slider, a guide rod, etc., see the details) for guiding during lifting is set between the lifting platform 130 and the base 110 Figure 3 ), to ensure smooth lifting and accurate movement. A lower clamping block 140 for clamping the bottom of the tire blank is arranged at the right end of the lifting platform 130, and an upper clamping block 150 for clamping the top of the tire blank is arranged above the lower clamping block 140. The upper clamping block 150 and the lower clamping block 140 are directly opposite to each other, and a clamping area for clamping the tire blank is formed between the two. A second driving component 160 is arranged on the upper clamping block 150, and the output end of the second driving component 160 has a degree of freedom in the up and down directions, so that the second driving component 160 can drive the upper clamping block 150 to move up and down. The cooperation of the upper clamping block 140 and the lower clamping block 150 can realize the clamping of the tire blank, that is, the tire blank can be taken out from the belt drum. In order to deliver the tire blank to the tire unloading station, a tire unloading mechanism 170 is arranged on the left side of the lower clamping block 140 (i.e., the side away from the guide channel 200). The execution end of the tire unloading mechanism 170 is directed toward the clamping area (or the guide channel 200), and a force perpendicular to the axial direction is applied to the tire blank to push the tire blank out of the clamping area. The position where the tire blank leaves the tire unloading device 100 is called the tire outlet. In this embodiment, the tire outlet is located on the right side of the tire unloading device 100.

[0042] When the tire unloading device 100 is in use, the base 110 moves to the tire blank clamping station, so that the lower clamping block 140 and the upper clamping block 150 move to the bottom and top of the tire blank respectively, and then the first driving component 120 drives the lifting platform 130 to move upward, so that the lower clamping plate 140 abuts against the bottom of the tire blank, and the second driving component 160 drives the upper clamping plate 150 to move downward, so that the upper clamping plate 150 abuts against the top of the tire blank, thereby clamping the tire blank in the clamping area, and then the belt drum releases the tire blank, and the tire blank is transferred to the tire unloading device 100. It should be noted that the tire blank is still in an upright state at this time. The base 110 moves to the tire unloading position so that the tire blank is opposite to the entrance 201 of the guide channel 200. At this time, the first driving component 120 and the second driving component 160 are reset, that is, the lower clamping plate 140 and the upper clamping plate 150 release the tire blank. At the same time, the tire unloading mechanism 170 is activated to apply a force perpendicular to the axis of the tire blank to the left side of the tire blank, pushing the tire blank to the right, so that the tire blank enters the guide channel 200.

[0043] like Figure 4 As shown, the base 110 includes a bottom plate 111 slidably disposed on the slide rail 600, an extension plate 112 fixedly disposed on the bottom plate 111 and extending to the left, and a bracket 113 ( Figure 4 The reason for the medium viewing angle is not shown, see Figure 3 ), the bracket 113 is arranged on the left side of the clamping area to ensure that the clamping area has enough space to clamp the tire blank. It should be noted that the bottom plate 111, the extension plate 112 and the bracket 113 can be three independent components, or they can be integrally formed in pairs or in three parts.

[0044] The first driving component 120 can be a cylinder, a hydraulic cylinder (such as an oil cylinder), and a screw rod. In this embodiment, a cylinder is used as an example. Figure 3 and Figure 4 As shown, the first driving component 120 is arranged longitudinally, and the lower end of the first driving component 120 is fixedly arranged on the extension plate 112. The output end (i.e., the piston rod) of the first driving component 120 faces upward and is connected to the lifting platform 130, so that the first component 120 can drive the lifting platform 130 to perform lifting movements.

[0045] like Figure 4 As shown, the lifting platform 130 is L-shaped, and includes a shell 131 disposed outside the bracket 113 and extending longitudinally, and a lifting plate 132 fixedly connected to the shell 131 and extending to the right side. The inner wall of the shell 131 is longitudinally slidably connected to the outer wall of the bracket 113, for example, by the cooperation between the slider and the slide rail (see Figure 3 ). In addition, the upper part of the housing 131 is connected to the output end of the first driving component 120, so that the housing 131 can slide on the bracket 113 in the longitudinal direction under the drive of the first driving component 120. Since the lifting plate 132 is fixedly connected to the housing 131, the lifting plate 132 is synchronously lifted and lowered when the housing 131 moves. The lifting plate 132 extends rightward to the lower part of the clamping area to facilitate the installation of the lower clamping block 140.

[0046] The lower clamping block 140 is arranged on the upper end surface of the lifting plate 132, and the lower clamping block 140 is preferably arranged directly below the clamping area, that is, when clamping, the lower clamping block 140 is preferably in contact directly below the tire blank to ensure the clamping effect of the tire blank. In addition, in order to improve the clamping stability, a lower clamping groove 141 is arranged on the upper end surface of the lower clamping block 140. The clamping groove is a structure with a concave middle and convex sides. For example, Figure 4In the embodiment, the lower clamping groove 141 is V-shaped, so that when clamping, the lower clamping groove 141 can support the tire blank from the bottom and provide the tire blank with horizontal force components from two opposite radial sides, ensuring that the tire blank is stably clamped.

[0047] Corresponding to the lower clamping block 140, the upper clamping block 150 is also preferably arranged just above the clamping area, so that when clamping, the upper clamping block 150 abuts just above the embryo. In addition, an upper clamping groove 151 is arranged on the lower end surface of the upper clamping block 150, and the shape of the upper clamping groove 151 can refer to the lower clamping groove 141, which will not be described in detail here.

[0048] Corresponding to the first driving component 120, the second driving component 160 can also be a cylinder, a hydraulic cylinder (such as an oil cylinder), and a screw rod, etc. In this embodiment, the cylinder is also used as an example. The second driving component 160 is fixedly arranged on one side of the transfer ring 500 through the adapter plate 161. The second driving component 160 is arranged longitudinally, and the output end (i.e., the piston rod) faces downward. The top of the upper clamping block 140 is connected to the output end of the second driving component 160. In addition, in order to ensure the stability of the upper clamping block 140 when moving, a guide component is also arranged on the adapter plate 161. Commonly, a guide rod (see Figure 4 ), the lower end of the guide rod is fixedly connected to the top surface of the upper clamping block 150, and the upper end of the guide rod is penetrated on the adapter plate 161.

[0049] like Figure 4 As shown, the tire unloading mechanism 170 includes a third driving component 171, and a tire unloading component 172 arranged on the execution end of the third driving component 171. The execution end of the third driving component 171 is arranged toward the tire outlet (not necessarily directly opposite to the tire outlet), and has the freedom to move linearly toward the position of the clamping area. Under the action of the third driving component 171, the tire unloading component 172 applies a thrust to the tire blank in the clamping area, thereby pushing the tire blank out of the clamping area.

[0050] As an example, the third driving component 171 can be a cylinder, and the third driving component 171 can be set horizontally, or can be set up or down. In addition, the third driving component can be set on the housing 131, or can be set on the lifting plate 132. The following examples are respectively described. When the third driving component 171 is set horizontally, the left end of the third driving component 171 is fixedly set on the right side of the housing 131, and the right end of the third driving component 171 is from the horizontal direction toward the clamping area. When the tire is unloaded, the third driving component 171 drives the tire unloading component 172 to move rightward from the left side, thereby pushing the tire to move rightward. When the third driving component 171 is set upwardly tilted, the left end of the third driving component 171 can be set on the housing 131, or can be set on the lifting plate 132, and the right end of the third driving component 171 is tilted toward the clamping area. When the tire is unloaded, the third driving component 171 drives the tire unloading component 172 to move toward the clamping area, thereby pushing the tire to move rightward. Similarly, the third driving component can be set on the housing 131 tilted downward. However, preferably, the third driving component 171 is arranged on the lifting plate 132 in an upwardly inclined manner.

[0051] The tire unloading component 172 can be a push block separately arranged on the execution end of the third driving component 171. The movement of the output end of the third driving component 171 drives the push block to move linearly to realize the tire unloading action. Figure 4 As shown, the tire unloading component 172 is a flip plate 173, and the tire blank is pushed to be unloaded by the flipping movement of the flip plate 173. Specifically, the right end (also called the connecting part) of the flip plate 173 is set on the lifting plate 132 by rotation (for example, shaft connection). In this case, the third driving component 171 needs to be set on the lifting plate 132 with an upward tilt. The left side of the flip plate 173 is connected to the output end of the third driving component 171. When the output end of the third driving component 171 moves to the right, the flip plate 173 will flip to the right, thereby applying a rightward force to the tire blank and pushing the tire blank out of the clamping area.

[0052] Furthermore, the lower clamping block 140 mentioned above may be disposed on the upper end surface of the flip plate 173 , so that when the flip plate 173 flips, the lower clamping block 140 flips synchronously, thereby pushing the green tire toward the guide channel 200 .

[0053] In addition, an auxiliary push plate 174 can be provided on the left side of the flip plate 173, and the auxiliary push plate 174 extends upward obliquely, so that an obtuse angle is formed between the auxiliary push plate 174 and the flip plate 173, and the auxiliary push plate 174 has a considerable axial length along the embryo (usually equal to the axial length of the embryo), so that the auxiliary push plate 174 can cover most of the axial length of the embryo, increase the contact area with the embryo during flipping, ensure that the flipping thrust can accurately act on the embryo, and avoid the embryo being unable to enter the guide channel 200 due to the deviation of the force direction. Specifically, when the flip plate 173 flips, the auxiliary push plate 174 will flip synchronously, and after flipping, the auxiliary push plate 174 will abut against the side of the embryo away from the guide channel 200, thereby pushing the embryo into the guide channel 200.

[0054] The tire unloading device 100 has the following beneficial effects: the tire green body is clamped by setting the lower clamping block 140 and the upper clamping block 150, the tire green body is axially moved by sliding the base 110 on the slide rail 600, and the tire green body is unloaded by setting the tire unloading mechanism 170, that is, the device realizes the function of automatically unloading the tire from the belt drum. In addition, the tire unloading mechanism 170 realizes the tire unloading by the flipping movement of the flip plate 171, ensuring that the tire green body can be accurately pushed out.

[0055] like Figure 1 As shown, the guide channel 200 includes a guide seat 210 located at the bottom, and baffles 220 arranged on the front and rear sides of the guide seat 210, the baffles 220 extend to the top of the guide seat 210, and the channel with openings on both ends formed by the upper end surface of the guide seat and the baffles 220 on the front and rear sides is the guide channel 200.

[0056] One end of the guide seat 210 faces and is close to the slide rail 600, and the height of the guide seat 210 is adapted to the height of the tire unloading device 100, so that the tire green body pushed out of the tire unloading device 100 can smoothly enter the guide channel 200. In addition, the guide seat 210 is preferably inclined so that the upper end surface of the guide seat 210 is higher on the left and lower on the right, so that after the tire green body enters the guide seat 210, it will roll downward along the upper end surface of the guide seat 210, and no additional components are required to push the tire green body to roll forward.

[0057] The baffles 220 on the front and rear sides can block the tire blank to prevent it from rolling out of the guide seat 210. In a preferred embodiment, Figure 1As shown, the baffle 220 includes a plurality of first rollers 221 that are rotatably arranged, and the first rollers 221 are arranged along the extension direction of the guide channel 200, and the axes of the first rollers 221 extend in the up-down direction, and specifically, the axes of the first rollers 221 are perpendicular to the upper end surface of the guide seat 210. When the embryo is in contact with the first rollers 221, the first rollers 221 rotate around their own axes, so that the embryo continues to roll forward along the extension direction of the guide channel 200.

[0058] It should be noted that the width of the guide channel 200 should not be too large to prevent the embryo from turning over to a flat state in the guide channel 200. Generally, the width of the guide channel 200 is 1.1-1.5 times the width of the embryo to ensure that the embryo is always in an upright state when rolling in the guide channel 200.

[0059] like Figure 1 and Figure 5 As shown, the tire turning device 300 has an input end 301 and an output end 302. The tire blank enters from the input end 301 and leaves from the output end 302. The input end 301 is connected to the outlet 202 of the guide channel 200. In this embodiment, the direction of the input end 301 and the direction of the output end 302 are perpendicular to each other. The tire turning device 300 includes a horizontally arranged tire turning seat 310. One side of the tire turning seat 310 ( Figure 5 The side of the tire turning seat 310 that is away from the input end 301 (or the guide channel 200) is toward and close to the guide channel 200, and this side is the input end 301. Figure 5 The tire turning seat 310 is provided with a stopper 320, which extends to the top of the tire turning seat 310. The stopper 320 is used to stop the tire embryo and make it stop on the tire turning seat 310. The tire turning seat 310 has an upper end surface, a stopper 320 and an input end 301 to form a tire entry passage 303 for the tire embryo to enter, that is, the input end 302 is located at the head end of the tire entry passage 303, and the stopper 320 is located at the tail end of the tire entry passage 303. The tire turning seat 310 is provided with a horizontal movement ( Figure 5 The first conveyor belt 330 (in the front-to-back direction), the discharge end of the first conveyor belt 330 ( Figure 5 The middle front side) is the output end 302. In this embodiment, the first conveyor belt 330 moves from the back to the front.

[0060] It should be noted that the first conveyor belt 330 is not in motion all the time. It will only be started after the tire blank enters the tire turning device 300. For example, a photoelectric sensor can be set at the entrance of the guide channel 200 to sense whether the tire blank enters the guide channel 200, and a corresponding delay control system can be set so that the first conveyor belt 330 is started after the tire blank enters the tire turning device 300.

[0061] When the tire turning device 300 is in use, the tire embryo enters the upper end surface of the tire turning seat 310 from the input end 301, and continues to roll along the tire inlet channel 303 until it collides with the blocking component 320. At this time, the tire embryo is rebounded in the opposite direction under the action of the reaction force. The above process may be repeated for many times, but the tire embryo will eventually stay on the first conveyor belt 330. As mentioned above, the first conveyor belt 330 is still in a stationary state at this time. When the tire embryo is stationary (the tire embryo may be in an upright state or in a flat state at this time), the first conveyor belt 330 is started, and the lower part of the tire embryo will move synchronously with the first conveyor belt 330. If the tire embryo is in an upright state, the upper part of the tire embryo will stop at the original position due to inertia, so that the tire embryo is tilted and will eventually flip to a flat state, and then be output from the first conveyor belt 330 in a flat state.

[0062] In order to prevent the tire blank from escaping from the tire inlet passage 303 due to collision with the stopper 320 or due to the angle of the tire blank when entering the tire inlet passage 303, a tire turning seat 310 is provided at one end ( Figure 5 A limiting frame 340 is provided at the middle and rear end of the tire inlet passage 303, and the limiting frame 340 serves as a baffle at the rear side of the tire inlet passage 303 to block the rear side of the tire inlet passage 303 to prevent the tire blank from falling out of the tire turning seat 310. Further, a second roller 341 can be provided on the limiting frame 340, and the second roller 341 is arranged to rotate along its own axis, so that when the tire blank contacts the second roller 341, it can guide the tire blank.

[0063] In addition, in order to ensure that each tire embryo can be smoothly flipped from an upright state to a flat state, a tire embryo passage opening 304 is provided on the side of the tire inlet channel 303 close to the output end 302. The height of the tire embryo passage opening 304 is greater than the width of the tire embryo, but less than 80% of the diameter of the tire embryo, so that the tire embryo in the flat state can smoothly pass through the tire embryo passage opening 304, while the tire embryo in the upright state cannot pass through the tire embryo passage opening 304 when moving on the first conveyor belt 330, and because the upper part of the tire embryo is blocked in the horizontal direction, the tire embryo tilts and finally flips to a flat state and passes through the tire embryo passage opening 304.

[0064] As a specific implementation of the embryo passage 304, a horizontally extending crossbar 350 (see Figure 1), a tire embryo passage 304 is formed between the cross bar 350 and the first conveyor belt 330. When the upright tire embryo contacts the cross bar 350, the middle and upper part of the tire embryo will be blocked by the cross bar 350, while the lower part of the tire embryo still moves synchronously with the first conveyor belt 330, thereby causing the tire embryo to flip. In addition, the cross bar 350 is arranged on one side of the tire inlet channel 303, and can act as a baffle on one side of the tire inlet channel 303 like the limit frame 340 mentioned above, so that the tire embryo rolls in the tire inlet channel 303 and is prevented from leaving the tire inlet channel 303.

[0065] As a specific example of the stopping component 320, the stopping component 320 may be a plate-like structure arranged longitudinally, but preferably, the stopping component 320 is made of a flexible material such as sponge or cloth, so that when the embryo contacts the stopping component 320, it can be quickly braked and thus stay on the first conveyor belt 330. In addition, the stopping component 320 may also be provided with an adjustment mechanism 321, which adjusts the horizontal position of the stopping component 320 to adapt to embryos of different specifications. Commonly, the adjustment mechanism 321 may be a screw rod (see Figure 5 ).

[0066] As an improvement of the first conveyor belt 330, the first conveyor belt 330 includes a first belt body 331 and a second belt body 332. The first belt body 331 and the second belt body 332 move synchronously, but a positioning groove 333 is provided between the first belt body 331 and the second belt body 332. The advantage of providing the positioning groove 333 is that when the embryo contacts the stop member 320 and rebounds back to the first conveyor belt 330, since the embryo is still in an upright state, the circumferential surface of the lower part of the embryo will sink into the positioning groove 333, thereby positioning the embryo and ensuring that the position of the embryo does not deviate, so that it can be accurately transported to the subsequent positioning and conveying device 400.

[0067] The beneficial effects of the tire turning device 300 are as follows: by setting the tire inlet channel 303 to guide the tire embryo into the tire turning seat 310, and by setting the stopping component 320 at the end of the tire inlet channel 303 to stop the tire embryo on the tire turning seat 310, by setting the first conveyor belt 330 to turn the tire embryo into a flat state and send it out, the automatic turning and conveying of the tire embryo is realized. Compared with the prior art in which the tire embryo is turned over by the movement of the cylinder, the device simplifies the structure and does not need to set up the cylinder. The tire turning action can be realized only by the cooperation of the stopping component 320 and the first conveyor belt 330, which is simple and practical. In addition, by setting the cross bar 350, it is ensured that each tire embryo can be smoothly turned from an upright state to a flat state. By setting the positioning groove 333, the tire embryo can be preliminarily positioned.

[0068] like Figure 1 and Figure 6As shown, the centering conveying device 400 includes an inclined conveying frame 410, the lower end of the conveying frame 410 is arranged adjacent to the output end 302 of the tire folding device 300, and a second conveyor belt 420 is arranged on the conveying frame 410. A first centering frame 430 and a second centering frame 440 are respectively arranged on both sides above the second conveyor belt 420 and along the conveying direction. A centering channel 401 is formed between the first centering frame 430 and the second centering frame 440. The centering channel 401 is in a shape with a large inlet and a small outlet, preferably an eight-shaped shape, and the first centering frame 430 and the second centering frame 440 are respectively provided with a first centering roller 431 and a second centering roller 441 on the side facing the inlet, and the axial direction of the first centering roller 431 and the second centering roller 441 is perpendicular to the plane where the second conveyor belt 420 is located.

[0069] When the centering conveying device 400 is in use, the embryo enters the lower end of the second conveyor belt 420 and moves upward under the action of the second conveyor belt 420. When the embryo is in the correct position, that is, the embryo is in the middle position of the second conveyor belt 420, the embryo will directly pass through the centering channel 401 and will not contact the first centering frame 430 and the second centering frame 440 on both sides. When the embryo deviates from the correct position, that is, when the embryo deviates to one side, the embryo will contact the first centering frame 430 or the second centering frame 440 on the corresponding side, so that under the action of the first centering roller 431 or the second centering roller 441, the embryo will move laterally until it is aligned with the centering channel 401, ensuring that the embryo is in the middle position of the second conveyor belt 420, so as to facilitate the subsequent placement of the embryo.

[0070] In order to facilitate the embryo to move left and right on the second conveyor belt 420 and adjust to the correct position, the second conveyor belt 420 is preferably a ball mesh chain conveyor belt, that is, a plurality of balls are evenly distributed on the surface of the second conveyor belt, and these balls need to have at least the freedom to rotate in the left and right directions to ensure that the embryo is subject to less friction when moving left and right.

[0071] Furthermore, an adjusting assembly 450 may be provided on the first centering frame 430 and the second centering frame 440, respectively. The first centering frame 430 and the second centering frame 440 may be swingably provided above the second conveyor belt 420 through the adjusting assembly 450. In this case, the size of the centering channel 401 may be adjusted, so that the centering conveying device 400 may convey and center embryos of different specifications. For example, when the size of the embryo is small, the centering channel 401 may be reduced accordingly to accommodate the embryo; similarly, when the size of the embryo is large, the centering channel 401 may be increased accordingly.

[0072] Specifically, in this embodiment, the adjustment assembly 450 on the first centering frame 430 is taken as an example, and the adjustment assembly 450 includes a rotating shaft 451, a rotating shaft mounting seat 452, a rotating plate 453, a connecting shaft 454, an adapter 455 and a driving element (not shown). The axial direction of the rotating shaft 451 is perpendicular to the plane where the second conveyor belt 420 is located, the upper end of the rotating shaft 451 is fixedly connected to the outer end of the first centering frame 430, the middle and lower parts of the rotating shaft 451 are rotatably arranged in the rotating shaft mounting seat 452, and the rotating shaft mounting seat 452 is fixedly arranged on the side of the conveying frame 410. The rotating plate 453 is fixedly arranged at the lower end of the rotating shaft 451, and a connecting shaft 454 is arranged on the rotating plate 453. The adapter 455 is hinged on the connecting shaft 454, and the output end of the driving element is connected to the adapter 455. The driving element can usually be a cylinder. The driving element can be arranged at the bottom of the conveying frame 410.

[0073] When the adjustment component 450 is in use, the driving element drives the adapter 455 to move, so that the adapter 455 drives the rotating plate 453 to rotate through the connecting shaft 454, and then the rotating shaft 451 rotates in the rotating shaft mounting seat 452, and finally the first centering frame 430 at the upper end of the rotating shaft 451 swings, thereby realizing the adjustment of the centering channel 401.

[0074] The beneficial effect of the centering conveying device 400 is: by arranging the first centering frame 430 and the second centering frame 440 above the second conveyor belt 420, a centering channel 401 is formed above the second conveyor belt 420, and the embryo passes through the centering channel 401 to ensure that the embryo is in the correct position to facilitate the subsequent removal and placement of the embryo.

Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present invention. Various modifications to these embodiments will be apparent to professionals and technicians in the field.
