Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, and in particular to a gripping component and a bead spacer gripping and stacking device. Background Technology

[0002] Triangular bead stacking is a crucial step in rubber tire production lines. During stacking, the bead pieces need to be separated by spacers. These spacers are mostly annular structures, and due to their shape, existing clamping mechanisms are difficult to use, hindering automation of spacer gripping. Therefore, this operation heavily relies on manual labor, resulting in low stacking efficiency and certain safety risks. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention provide a gripping component and a bead spacer gripping and stacking device, wherein the gripping component provides a novel material gripping structure, which is particularly suitable for annular bead spacers.

[0006] The gripping component provided according to an embodiment of the present invention includes a mounting plate, gripping components, and an actuating component. The number of gripping components is two, and both are slidably disposed on the mounting plate. The opposite sides of the two gripping components protrude outward and form a locking block that can cooperate with the inner side of the material to be gripped. The actuating component is provided with two movable parts that can move closer to each other or move further away from each other. The gripping components are connected to the movable parts and can move closer to each other or further away from each other when pulled by the movable parts.

[0007] The gripping component of this invention provides a novel structure suitable for gripping tire bead septums. This gripping component, through two movable parts, can pull the corresponding gripping assembly along a fixed path towards or away from each other, and in this process, the gripping and release of the tire bead septum to be gripped is achieved by a locking block formed on the gripping assembly.

[0008] In some embodiments, the actuating component is a V-shaped structure, including two rotatably connected links, the other ends of which form the movable element.

[0009] In this embodiment of the invention, the gripping component can achieve relative proximity or separation of moving parts through two rotatably connected rods, thereby driving the two gripping components to move in opposite directions.

[0010] In some embodiments, the actuation component further includes a retractable first linear drive mechanism, the retractable end of which is connected to the connection point of the two links.

[0011] The gripping component of this invention can be driven by a first linear drive mechanism to reciprocate along a fixed path at the connection point of the two connecting rods. During this process, the movable part formed on the free end of the connecting rod can move closer or further away synchronously under the drive of the first linear drive mechanism, so that the gripping component can pick up and put away the tire bead spacer.

[0012] In some embodiments, the latch is a flange extending along the outer periphery of the gripping assembly, and a support surface is formed on the flange for lifting the material to be gripped.

[0013] In the gripping member of this embodiment of the invention, the aforementioned flange and the supporting surface formed on the flange can make the connection between the gripping block and the gripped tire bead septum more secure.

[0014] In some embodiments, the gripping assembly includes a sliding connector and a gripping member that are fixedly connected, the sliding connector being connected to the mounting plate and the actuation assembly, and the locking block being formed on the gripping member.

[0015] In some embodiments, the mounting plate is provided with a linear slide rail, and the sliding connector slides in conjunction with the linear slide rail.

[0016] In some embodiments, a plurality of gripping suction cups are also fixedly mounted on the mounting plate, the gripping suction cups and the gripping assembly are located on the same side of the mounting plate and the gripping suction cups are located outside the movement path of the gripping assembly.

[0017] The gripping component of this invention, the suction cup described above, can be used alone or in conjunction with the gripping assembly to realize the picking and placing of the tire bead spacer.

[0018] The tire bead spacer gripping and stacking device provided according to an embodiment of the present invention includes a swinging component and a gripping component. The swinging component includes a swing arm and a rotation drive assembly. The rotation drive assembly is connected to the swing arm and can drive the swing arm to swing around a fixed rotation axis. The gripping component is located at the swinging end of the swing arm, and the gripping component is any of the gripping components described above.

[0019] The bead spacer gripping and palletizing device of this invention can grip the bead spacer through the gripping component and transfer the gripped bead spacer to the palletizing position through the swinging component. Its overall structure is compact and occupies little space. It can be used in conjunction with other equipment to effectively improve the bead spacer gripping and palletizing efficiency.

[0020] In some embodiments, the rotation drive assembly includes a gear, a rack, and a second linear drive mechanism, wherein the gear and the rack mesh with each other, the second linear drive mechanism is connected to the rack and drives the rack to move in a straight line, and the gear is fixedly connected to the swing arm.

[0021] In the tire bead spacer gripping and stacking device of this invention, the rotation drive component can drive the gear to rotate through a gear and rack meshing mechanism and a second linear drive mechanism that can drive the rack to move along its length direction, and in this process drive the swing arm to swing, thereby completing the rapid transfer of the tire bead spacer position.

[0022] In some embodiments, the tire bead septum gripping and palletizing device further includes a lifting component, which includes a column, a lifting assembly, and a slide. The lifting assembly is disposed on the column along the axial direction of the column, and the slide moves up and down relative to the column through the lifting assembly. The rotation drive assembly is fixedly installed on the slide.

[0023] The tire bead spacer gripping and stacking device of this invention can drive the swinging component and gripping component to move up and down through the lifting component to adapt to different stacking heights. Attached Figure Description

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is combined with Figures 1-8 This invention describes a gripping member and a tire bead septum gripping and stacking device according to embodiments of the present invention.

[0037] The gripping component provided in the embodiments of the present invention, such as Figures 1-4 As shown, the gripping component includes a mounting plate 1, gripping components 2, and an actuating component 4. There are two gripping components 2, both of which are slidably mounted on the mounting plate 1. The opposite sides of the two gripping components 2 protrude outward and form a locking block 21 that can cooperate with the inner side of the material to be gripped. The actuating component 4 is provided with two movable parts 401 that can move closer to each other or move further away from each other. The gripping components 2 are connected to the movable parts 401 and can move closer to each other or move further away from each other when pulled by the movable parts 401.

[0038] Most bead septa are annular structures. The gripping component provided in this embodiment of the invention discloses a novel gripping structure that can utilize the annular characteristics of the bead septa to complete the gripping operation.

[0039] Unlike traditional clamps that rely on the jaws to come close together to hold an object, the gripping component in this embodiment reduces the overall size of the gripping components by bringing them closer together, thereby inserting them into the hollow structure of the bead spacer to achieve initial contact with the bead spacer. Subsequently, by controlling the two gripping components to move away from each other, the protrusions on the opposite sides of the gripping components engage with the bead spacer to achieve the gripping of the bead spacer.

[0040] Since the gripping assembly slides relative to the mounting plate 1, the movable part 401 in the above-mentioned action assembly 4 can be pulled to move closer or further away from each other along a fixed path, and in this process, the gripping and release of the tire bead septum to be gripped is achieved by the locking block 21 formed on the gripping assembly 2.

[0041] It should be noted that the aforementioned fixed path is a sliding path formed on the mounting plate 1, and the sliding path is set to extend in a straight line.

[0042] Specifically, the mounting plate 1 can be equipped with a linear slide rail 11, and the gripping component 2 can slide relative to the mounting plate 1 via the linear slide rail 11.

[0043] In some embodiments, the aforementioned actuating component 4 may be composed of a gear and rack meshing structure. For example, two racks meshing with the same gear and located at the radial ends of the gear may move synchronously in opposite directions as the gear rotates, thereby achieving the aforementioned effect.

[0044] Alternatively, in other embodiments, the motion component 4 can be configured as a V-shaped structure, comprising two connecting rods 41. One end of the two connecting rods 41 is connected by a rotatable connection, and the other end forms a movable part 401. When the connection between the two connecting rods 41 is pulled, the two movable ends will move closer or further apart as the connecting rods 41 are pulled, thereby driving the two gripping components 2 to move in opposite directions.

[0045] Specifically, the connecting parts of the two connecting rods 41 mentioned above can be connected by pivoting, or by meshing or other methods disclosed in related technologies.

[0046] It should be noted that the movable end of the pivotally connected link 41 will swing when the link 41 is pulled. In order to ensure that the movable end of the link 41 can be firmly connected to the gripping component 2 and will not affect the sliding of the gripping component 2, the movable end of the link 41 is hinged or pivotally connected to the gripping component 2.

[0047] In order to better control the action of the above-mentioned action component 4, in some embodiments, the action component 4 further includes a retractable first linear drive mechanism 42, the retractable end of the first linear drive mechanism 42 being connected to the connection point of the two connecting rods 41.

[0048] The first linear drive mechanism 42 can drive the connection point of the two connecting rods 41 to reciprocate along a fixed path. During this process, the movable part 401 formed on the free end of the connecting rod 41 can move closer or further away synchronously under the drive of the first linear drive mechanism 42. When the two movable parts 401 move closer to each other, the gripping component 2 can be inserted into the hollow structure of the tire bead spacer to be picked up. When the two movable parts 401 move further away from each other, the tire bead spacer sleeved outside the gripping component 2 will be gripped under the support of the locking block 21.

[0049] Specifically, the first linear drive mechanism 42 mentioned above is a cylinder.

[0050] To facilitate the insertion of the gripping component 2 into the hollow structure of the bead septum to be picked up, in this embodiment, the outer edge of the opposite side of the gripping component 2 is an outwardly convex arc-shaped sidewall, the size of which matches the hollow structure of the bead septum. When the two gripping components 2 approach each other until they are in contact, the axial cross-section of the outer sidewalls of the two gripping components 2 is circular or approximately circular. Alternatively, the insertion end of the gripping component 2 can also be a conical or similar conical surface.

[0051] It should also be noted that the size and shape of the gripping component 2 can be adjusted according to the actual size of the tire bead spacer to be gripped.

[0052] To make the connection between the gripping component 2 and the bead spacer more secure, in some embodiments, the locking block 21 is a flange extending along the outer periphery of the gripping component 2, and a supporting surface 211 for supporting the material to be gripped is formed on the flange, such as... Figure 1-4 As shown.

[0053] In addition to the above structure, the above-mentioned card block 21 can also be a serrated shape or other structure evenly distributed on the outside of the gripping component 2, as long as a supporting surface 211 for supporting the bead spacer to be gripped can be formed on its upper side.

[0054] Since the gripping component 2 needs to be slidably connected to the mounting plate 1 and connected to the connecting rod 41, in some embodiments, for ease of installation and replacement, the gripping component 2 includes a fixedly connected sliding connector 22 and a gripping component 23, wherein the sliding connector 22 is connected to the mounting plate 1 and the actuating component 4, and the gripping component 23 is used to pick up and put down the tire bead spacer. A locking block 21 is formed on the gripping component 23.

[0055] When the size of the tire bead septum to be gripped is different, the applicability of the gripping component 2 can be improved by changing the gripping part 23.

[0056] The sliding connector 22 and the gripper 23 can be connected by publicly available connection methods or structures that can achieve a fixed connection, such as bonding, snap-fitting, welding or bolting. This embodiment does not limit the connection method of the sliding connector 22 and the gripper 23.

[0057] In addition to the above structure, in some embodiments, a plurality of gripping suction cups 3 are also fixedly installed on the mounting plate 1. The gripping suction cups 3 and the gripping component 2 are located on the same side of the mounting plate 1 and the gripping suction cups 3 are located outside the movement path of the gripping component 2.

[0058] The number of suction cups is at least two, and all suction cups are evenly distributed outside the movement paths of the two gripping components 2.

[0059] like Figure 1 As shown, there are four suction cups, which are evenly distributed at the four corners of the mounting plate 1, and the gripping component 2 is located in the middle of the mounting plate 1.

[0060] When picking up the bead spacer, the suction cup can be used in conjunction with the gripping component 2, or it can be used alone.

[0061] Generally speaking, for hollow annular bead septa, gripping component 2 is used to grip them directly; for non-hollow bead septa, suction cups are generally used for gripping.

[0062] To avoid interference between the suction cup and the gripping component 2 during use, in some embodiments, the suction cup structure can be installed as needed.

[0063] It is understood that the gripping component provided in this embodiment can easily pick up and put down the annular bead spacer through a special structural design, thereby realizing the automated gripping of the bead spacer, effectively improving the efficiency of bead stacking, and reducing the safety risks caused by manual intervention in the above-mentioned operations.

[0064] The tire bead spacer gripping and palletizing device provided in this embodiment of the invention, such as Figure 5-8 As shown, the tire bead spacer gripping and stacking device includes a swinging component and a gripping component. The swinging component includes a swing arm 5 and a rotation drive assembly 6. The rotation drive assembly 6 is connected to the swing arm 5 and can drive the swing arm 5 to swing around a fixed axis. The gripping component is located at the swinging end of the swing arm 5 and is any of the gripping components described above.

[0065] The device uses the aforementioned gripping component to grip the tire bead spacers, and can also transfer the gripped tire bead spacers to the stacking position through the swinging component. Its overall structure is compact and occupies little space, and can be used in conjunction with other equipment to effectively improve the efficiency of gripping and stacking tire bead spacers.

[0066] It should be noted that the aforementioned gripping component needs to move up and down within a certain range during operation to complete the gripping action. To achieve this effect, a buffer assembly capable of moving up and down within a small range can be installed outside the gripping component. This buffer assembly includes a guide cylinder, which is fixedly installed on the aforementioned swing arm 5. Simultaneously, its telescopic end can control the mounting plate 1 and its connected components to move freely up and down within a certain range, achieving buffering and control of the gripping component's movement to its endpoint during the gripping and releasing of the spacer. The connection structure between the telescopic end and the mounting plate 1 is existing technology and will not be described in detail here.

[0067] In some embodiments, the rotation drive assembly 6 includes a gear 61, a rack 62, and a second linear drive mechanism 63. The gear 61 and the rack 62 mesh with each other. The second linear drive mechanism 63 is connected to the rack 62 and drives the rack 62 to move in a straight line. The gear 61 is fixedly connected to the swing arm 5.

[0068] like Figure 8 As shown, the second linear drive mechanism 63 and the rack 62 are arranged side by side in the same direction, and the telescopic end of the second linear drive mechanism 63 is connected to the rack 62 through a push block 64. When the telescopic end of the second linear drive mechanism 63 moves telescopically, the rack 62 moves synchronously and drives the gear 61 to rotate. The swing arm 5, which is fixedly connected to the gear 61, will swing under the drive of the gear 61. At this time, the gripping component located at the swing end of the swing arm 5 can quickly change position as the swing arm 5 swings.

[0069] Specifically, the second linear drive mechanism 63 mentioned above is a cylinder.

[0070] In some embodiments, the tire bead septum gripping and palletizing device further includes a lifting component, which comprises a column 7, a lifting assembly 8, and a slide 9. The lifting assembly 8 is axially mounted on the column 7, and the slide 9 moves up and down relative to the column 7 via the lifting assembly 8. A rotation drive assembly 6 is fixedly mounted on the slide 9. The lifting assembly 8 consists of a motor, a drive wheel, a driven wheel, a chain, and a lifting guide rail. The slide 9 is connected to the chain and slides along the lifting guide rail. When the motor starts, the drive wheel rotates, driving the chain and the driven wheel to rotate. The slide 9, located on the chain, slides along the lifting guide rail under the pull of the chain, thereby driving the swinging component and gripping component located on the slide 9 to move up and down. The structure of the lifting assembly 8 described above is prior art and will not be described in detail here.

[0071] In this embodiment, the aforementioned tire bead spacer gripping and stacking device can use a lifting component to drive the swinging component and gripping component to move up and down to adapt to different stacking heights.

[0072] In addition to driving the swinging and gripping components to move up and down during the tire bead stacking process, the aforementioned lifting components can also drive the gripping components to move up and down within a certain range during the gripping of tire bead spacers, so as to realize the gripping, transfer and release of tire bead spacers.

[0073] In order to install the swing component on the lifting component, specifically, the second linear drive mechanism 63 in the rotation drive assembly 6 can be fixedly installed on the slide 9 by means of bolts or other structures, and the swing arm 5 and gear 61 are installed on the slide 9 by means of a slewing bearing.

[0074] The aforementioned slewing bearing and gear 61 are an integral structure.

[0075] The bead spacer gripping and palletizing device is used as follows:

[0076] First, adjust the arrangement of the device and the structure of the gripping component according to the position of the diaphragm car and the empty car to be stacked, so that the gripping component is exactly located in the diaphragm car position or the empty car position.

[0077] After the device is debugged and stabilized, the swing component rotates, causing the gripping component to rotate above the spacer cart and its height is adjusted so that the gripping component can grip the tire bead spacer at the spacer cart through the gripping component 2 or the suction cup. Then, the lifting component controls the swing component to return to the initial height, and the swing component rotates to the spacer to be stacked. The lifting component controls the swing component to move downward to a suitable height again, and controls the gripping component to release the tire bead spacer.

[0078] Simply repeat the above process.

[0079] Understandably, compared with other bead spacer gripping and palletizing devices, the bead spacer gripping and palletizing device provided in this embodiment provides a new gripping component, realizes the automation of bead spacer gripping, and effectively reduces the space occupied by the device through the swing component, which can better cooperate with other equipment and help to realize fully automatic bead palletizing operation.
