Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing, and in particular to a tire destacking machine for conveyor lines. Background Technology

[0002] In modern automobile manufacturing plants, tires are typically transported in stacks to the unloading area of ​​the final assembly workshop. To improve unloading efficiency, the entire stack is usually unloaded onto a roller conveyor line. In the automobile assembly line, tires are generally transported by stacking multiple tires on roller conveyors, and then broken down into individual tires in the assembly section for easier assembly.

[0003] The existing authorization announcement is CN204038634U, which discloses a tire destacking machine, including: a fixed frame (1) with a pre-embedded steel plate (2) fixed at the bottom end; a cylinder (4) installed at the top end of the fixed frame (1) via a cantilever frame (3); the output shaft of the cylinder (4) is hinged to two connecting rods (5); the other end of each connecting rod (5) is hinged to one end of a swing rod (6); the middle of the swing rod (6) is hinged to the fixed frame (1); and a chuck (7) is installed at the other end of the swing rod (6). The lower layer of the fixed frame (1) is connected to the lifting frame (8). The lifting frame (8) is equipped with a drive motor (9) and a linear slide rail (12). The output shaft of the drive motor (9) is equipped with a cam follower (11) via a crank (10). The linear slide rail (12) is matched with a slider (13). The slider (13) is connected to a movable frame (14). A roller bed (15) is fixed on the movable frame (14). The cam follower (11) is in contact with the movable frame (14).

[0004] The aforementioned prior art tire destacking device can only clamp one tire at a time for handling and destacking. This process is repeated to remove multiple tires from the stack in stages. This method undoubtedly increases the number of handling operations and requires 16 steps (see CN204038634U patent document, paragraphs 0011-0027 of the specification for details) to remove the next tire. The disassembly steps are cumbersome and reduce the tire destacking efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tire destacking machine for conveyor lines to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a tire destacking machine for a conveyor line, including a gantry frame set on a tire production line, a crossbeam detachably installed on the top of the gantry frame, and two rolling clamping mechanisms for clamping tires slidably installed on the bottom of the crossbeam, with the bottom of the rolling clamping mechanisms extending to the production line.

[0007] The top of the crossbeam is also provided with a drive mechanism, which has two connection points for connecting the rolling clamping mechanism, so as to drive the two rolling clamping mechanisms to move relative to each other to clamp the stacked tires.

[0008] Each of the aforementioned rolling clamping mechanisms includes a rolling unit. Two rolling units clamp multiple stacked tires and move downwards synchronously, so that the multiple stacked tires are gradually moved downwards to achieve orderly release and unstacking of the stacked tires.

[0009] Preferably, the rolling unit includes a bracket, a reducer, a driving roller, a driven roller, a belt, and a baffle. The bracket is slidably installed at the bottom of the crossbeam. The upper and lower ends of the bracket are respectively mounted with the driving roller and the driven roller. The baffle is detachably installed on the driving roller and the driven roller. The belt is sleeved on the driving roller and the driven roller, and the baffle contacts one side of the belt. The reducer is installed at the top of the bracket and is connected to the driving roller for transmission.

[0010] Preferably, the driving mechanism includes a cylinder, a connecting plate, and a connecting rod. The cylinder is detachably mounted on the top of the crossbeam, the connecting plate is hinged to the bottom of the crossbeam, and a connecting rod is hinged to each end of the connecting plate. The other end of the connecting rod is hinged to a bracket. The piston end of the cylinder is connected to one of the brackets. Under the action of the connecting plate and the connecting rod, the two rolling clamping mechanisms are driven to move synchronously relative to each other.

[0011] Preferably, the driving mechanism further includes two linear guide rails disposed at the bottom of the crossbeam, each linear guide rail having multiple sliders slidably mounted on it. The multiple sliders are respectively connected and assembled with two brackets to cooperate with the driving mechanism to make the rolling clamping mechanism move horizontally and stably at the bottom of the crossbeam.

[0012] Preferably, the diameter of the driving roller is at least twice that of the driven roller to increase the contact area between the driving roller and the belt.

[0013] Preferably, one side of the driving roller and the driven roller are in a vertical and horizontal state, so that one side of the belt is vertical and horizontal in order to stably clamp the stacked tires.

[0014] Preferably, a guardrail is detachably installed at the front end of the gantry frame.

[0015] Preferably, the connecting plate and the connecting rod form an obtuse angle in the initial state.

[0016] Preferably, four sliders are mounted on both sides of the top surface of each bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a drive mechanism to drive a rolling clamping mechanism closer together, so that two rolling units clamp multiple stacks of tires. Then, the two rolling units move downwards synchronously, causing the multiple stacks of tires to gradually move down, realizing the orderly release and unpacking of the stacked tires. It can clamp multiple stacks of tires at once and then release and unload them in an orderly manner, replacing the previous method of clamping one tire at a time for disassembly. This greatly reduces the number of times tires need to be handled and simplifies the disassembly steps, thereby improving the efficiency of tire unpacking. Attached Figure Description

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0027] This utility model provides a tire depalletizing machine for conveyor lines, such as... Figure 1-6As shown, the assembly includes a gantry frame 1, a crossbeam 2, a drive mechanism 3, and two rolling clamping mechanisms 4 for holding tires on the tire production line. A lifting device is also installed on top of the gantry frame 1 to elevate the equipment. The lifting device includes a motor, sprockets, and a chain. The gantry frame 1 is raised and lowered by extending and retracting the chain. The lifting principle can be found in references CN209306903U and CN221397108U, etc. This lifting device is existing technology and will not be described in detail here.

[0028] A crossbeam 2 is detachably mounted on the top of the gantry frame 1. Two rolling clamping mechanisms 4 are slidably mounted on the bottom of the crossbeam 2, and the bottom of the rolling clamping mechanisms 4 extends to the production line. Specifically, each rolling clamping mechanism 4 includes a rolling unit. A drive mechanism 3 is also provided on the top of the crossbeam 2. The drive mechanism 3 is provided with two connection points for connecting the rolling clamping mechanisms 4, so as to drive the two rolling clamping mechanisms 4 to move relative to each other to clamp the stacked tires.

[0029] When clamping tires, the drive mechanism 3 drives the rolling clamping mechanism 4 to move closer, causing the two rolling units to clamp multiple stacks of tires. Then, the two rolling units move downwards synchronously, gradually lowering the multiple stacks of tires to achieve orderly unpacking and destabilization of the stacked tires. Clamping multiple stacks of tires at once and then unpacking them in an orderly manner replaces the previous method of clamping and disassembling one tire at a time, greatly reducing the number of times tires need to be handled and simplifying the disassembly steps, thereby improving the efficiency of tire destabilization.

[0030] In this embodiment, the rolling unit includes a bracket 41, a reducer 42, a drive roller 43, a driven roller 44, a belt 45, and a baffle 46. The bracket 41 is slidably installed at the bottom of the crossbeam 2. The upper and lower ends of the bracket 41 are respectively mounted with the drive roller 43 and the driven roller 44. The baffle 46 is detachably installed on the drive roller 43 and the driven roller 44. The belt 45 is sleeved on the drive roller 43 and the driven roller 44, and the baffle 46 contacts one side of the belt 45. The reducer 42 is installed at the top of the bracket 41 and is connected to the drive roller 43 for transmission.

[0031] Specifically, in the clamping state, the baffle 46 provides a blocking force to the belt 45 to clamp the tire. When the stacked tires are transported downwards, the reducer 42 drives the drive roller 43 to rotate clockwise. With the cooperation of the driven roller 44, the belt 45 rotates downwards, so that the stacked tires move downwards synchronously. When the bottom tire is dislodged from the bottom of the belt 45, it falls onto the production line and is transported to the next process, thus completing the destacking process. The tires can be prevented from stacking on the production line by controlling the operating speed of the reducer 42 (i.e., the speed at which the tires fall).

[0032] In this embodiment, the drive mechanism 3 includes a cylinder 31, a connecting plate 32, and a connecting rod 33. The cylinder 31 is detachably mounted on the top of the crossbeam 2. The connecting plate 32 is hinged to the bottom of the crossbeam 2, and a connecting rod 33 is hinged to each end of the connecting plate 32. The other end of the connecting rod 33 is hinged to the bracket 41. The piston end of the cylinder 31 is connected to one of the brackets 41. Under the action of the connecting plate 32 and the connecting rod 33, the two rolling clamping mechanisms 4 are driven to move synchronously relative to each other.

[0033] Specifically, when the two rolling clamping mechanisms 4 are driven to approach each other, the cylinder 31 retracts, causing one of the connected brackets 41 to slide at the bottom of the crossbeam 2 and move towards the center. The gradually approaching bracket 41 presses against the connecting rod 33. Under the action of hinge with the bracket 41 and the connecting rod 33, the connecting rod 33 is forced to push the connecting plate 32 to rotate at the bottom of the crossbeam 2, thereby causing the connecting rod 33 and the connecting plate 32 to rotate and fold. The rotating connecting plate 32 also drives the other connecting rod 33 to rotate in the opposite direction, thereby pulling the other bracket 41 closer to the center until the two rolling clamping mechanisms 4 complete the clamping of the tire.

[0034] It can be explained here that the connecting plate 32 and the connecting rod 33 initially form an obtuse angle. The two ends of the connecting rod 33 are respectively hinged to the bracket 41 and the connecting plate 32. When the cylinder 31 retracts and drives the bracket 41 to move closer to the center, it facilitates the rotation and folding of the connecting rod 33. This avoids the situation where when the connecting rod 33 is horizontal with the bracket 41 and the connecting plate 32, the two ends of the connecting rod 33 will have relative abutment force with the bracket 41 and the connecting plate 32, which would prevent the connecting rod 33 from rotating and folding relative to the bracket 41 and the connecting plate 32.

[0035] In this embodiment, the drive mechanism 3 also includes two linear guide rails 34 disposed at the bottom of the crossbeam 2. Each linear guide rail 34 is slidably mounted with multiple sliders 35. The multiple sliders 35 are respectively connected and assembled with two brackets 41 to cooperate with the drive mechanism 3 to make the rolling clamping mechanism 4 move horizontally and stably at the bottom of the crossbeam 2.

[0036] Specifically, each bracket 41 is equipped with four sliders 35 on both sides of its top surface. The four sliders 35 slide the bracket 41 onto the linear guide rail 34, increasing the stability of the bracket 41 during movement and ensuring that the bracket 41 moves horizontally.

[0037] In this embodiment, the diameter of the active roller 43 is three times that of the driven roller 44, which increases the surface area of ​​the active roller 43 to increase the contact area between the active roller 43 and the belt 45. As a result, when the reducer 42 drives the active roller 43 to operate, the slippage between the belt 45 and the active roller 43 is reduced, so as to ensure that the belt 45 operates stably to roll and lower the tire.

[0038] Furthermore, one side of the driving roller 43 and the driven roller 44 are in a vertical and horizontal state, so that one side of the belt 45 is vertical and horizontal in order to stably clamp the stacked tires.

[0039] In this embodiment, a guardrail 5 is detachably installed at the front end of the gantry frame 1. The guardrail 5 is used to provide an aerial standing position for maintenance personnel to facilitate maintenance and testing of the equipment.

[0040] The working principle of this utility model is as follows: First, the lifting device lowers the gantry frame 1 to a position where the rolling clamping mechanism 4 is level with the bottom of the stacked tires; then, the cylinder 31 retracts to drive one bracket 41 to move, and under the action of the connecting rod 33 and the connecting plate 32, it pulls the other bracket 41 closer to the center until the two rolling clamping mechanisms 4 complete the clamping of the tires; then, the lifting device is used again to lift the gantry frame 1 until the bottom tires exceed the height of the production line; finally, the reducer 42 drives the drive roller 43 to rotate clockwise, and with the cooperation of the driven roller 44, the belt 45 rotates downward, so that the stacked tires move downward synchronously. When the bottom tire is dislodged from the bottom of the belt 45, it falls onto the production line and is transported to the next process, thus completing the destacking process.

[0041] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0042] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
