Description

Technical Field

[0001] The utility model relates to the technical field of tire stacking, and particularly relates to a tire stacking machine. Background Art

[0002] In order to facilitate the storage and transportation of tires, the produced tires are usually placed one by one in a special tire stacking rack for subsequent transfer by a forklift. However, it is difficult for manual labor to align the stacked tires coaxially, resulting in the need for manual readjustment of the tires during transportation, low transportation efficiency, and certain safety hazards. Content of the Utility Model

[0003] In order to overcome the deficiencies of the background art, the technical solution adopted by the utility model is: a tire stacking machine, including a main body frame, a lifting frame, a transmission cylinder, and a side clamping mechanism. The main body frame is connected with a transmission cylinder for vertically transporting the lifting frame, and the lifting frame is connected with a side clamping mechanism for positioning and centering.

[0004] The side clamping mechanism includes a sprocket, a synchronous chain, side clamping arms, side clamping cylinders, and rubber rollers. The lifting frame is connected with a sprocket for meshing and connecting the synchronous chain, and a side clamping cylinder for horizontally transporting the side clamping arms. The side clamping arms are symmetrically distributed at both ends of the lifting frame through linear slide rails, and the side clamping arms on both sides are clamped to the synchronous chain, and rubber rollers for clamping the tires are vertically distributed on the side clamping arms.

[0005] By adopting the above technical solution, the distance between the two groups of side clamping arms is controlled by the side clamping cylinder, so that the side clamping mechanism is compatible with different specifications of tires with an outer diameter of 900mm - 500mm. The height of the side clamping mechanism is controlled by the two side transmission cylinders, and tires with a thickness of 165mm - 350mm can be stacked, improving the scope of use of the equipment and realizing multi-purpose of one machine. Compared with manual stacking, the utility model has the advantages of high efficiency, neat forming, high safety, and low cost.

[0006] The utility model is further arranged such that the side clamping arm includes a bottom plate, side plates, floating columns, linear bearings, and a fixing frame. The bottom plate is slidably connected to the lifting frame through a linear slide rail. Two groups of parallel side plates are vertically distributed on the bottom plate, and the side plates are fixedly connected with floating columns, and the floating columns are slidably connected with a fixing frame through linear bearings. The rubber rollers are rotatably connected to both sides of the fixing frame.

[0007] Furthermore, a proximity switch is arranged between the fixing frame and the side plate.

[0008] With the above technical solution, the side clamping cylinder controls the side clamping arms to move towards each other or in opposite directions, so as to realize the grasping of the tire. When the side clamping mechanism grasps the tire and is in a suspended state, due to the action of gravity, the fixing frame is located below the floating column, and the fixing frame presses tightly against the proximity switch. When the side clamping mechanism stacks the tires, the tire receives a supporting force, and at this time, the tire drives the fixing frame to move slightly upward, and the fixing frame moves away from the proximity switch, so as to realize judging whether the tire stacking is completed by the proximity switch and provide a reference signal for the automatic tire stacking.

[0009] The present utility model is further configured such that the transmission cylinders are symmetrically distributed at both ends of the lifting frame, and positioning plates are provided at both ends of the lifting frame, as well as a first rubber wheel rotatably connected to the lifting frame and a second rubber wheel rotatably connected to the positioning plate. Rectangular columns for connecting the first rubber wheel and the second rubber wheel are provided on both sides of the main body frame, and the axial directions of the first rubber wheel and the second rubber wheel are perpendicular to each other.

[0010] With the above technical solution, a double-cylinder structure is adopted to control the movement of the lifting frame, improving the stability of the transmission structure, and the perpendicularity of the lifting frame during movement is maintained by the first rubber wheel and the second rubber wheel.

[0011] The present utility model is further configured such that transfer plates and fixing blocks are provided at both ends of the lifting frame, and the fixing blocks are parallel to the lifting frame through the transfer plates. The fixing blocks are provided with long holes for connecting the sprockets, and the sprockets are rotatably connected between the fixing blocks and the bottom plate.

[0012] Furthermore, a floating joint for connecting the side clamping arm is provided at the output end of the side clamping cylinder, and a connecting member for connecting the synchronous chain is provided on the bottom plate. The connecting member is provided with a clamping groove for clamping the floating joint.

[0013] Furthermore, two groups of chain supports for positioning the synchronous chain are provided between the side clamping arms where the lifting frame is located.

[0014] With the above technical solution, the sprockets at both ends of the lifting frame are connected between the fixing blocks and the bottom plate by bolts. The synchronous chain is meshed with the sprockets to form a ring shape. The stability of the synchronous chain transmission structure is maintained by the chain supports. The two side clamping arms on both sides are fixed on the same synchronous chain through the connecting members, so that their movement amounts are the same, maintaining the centering effect and making the stacked tires coaxial.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. By controlling the distance between the two groups of side clamping arms through the side clamping cylinder, the side clamping mechanism is made compatible with tires of different specifications. The height of the side clamping mechanism is controlled by the two side transmission cylinders on both sides, and tires of different thicknesses can be stacked, improving the scope of use of the equipment and realizing multi-purpose use of one machine;

[0017] 2. The centering effect of the side clamping mechanism is maintained by a synchronous chain, so that the stacked tires are coaxially distributed.

[0027] Combined with Figure 3As shown, in this embodiment, the side clamping arm 7 includes a bottom plate 71, side plates 72, floating columns 73, linear bearings 74, and a fixing bracket 75. The bottom plate 71 is slidably connected to the lifting frame 2 through a linear slide rail.

The floating columns 73 are slidably connected with a fixing bracket 75 through linear bearings 74. Rubber rollers 9 are rotatably connected to both sides of the fixing bracket 75. A proximity switch 10 is provided between the fixing bracket 75 and the side plates 72.

[0028] Combined with Figures 4 - 6 As shown, in this embodiment, the driving cylinders 3 are symmetrically distributed at both ends of the lifting frame 2. Positioning plates 21 are provided at both ends of the lifting frame 2, a first rubber wheel 22 rotatably connected to the lifting frame 2, and a second rubber wheel 23 rotatably connected to the positioning plate 21. Rectangular columns 11 for connecting the first rubber wheel 22 and the second rubber wheel 23 are provided on both sides of the main body frame 1. The axes of the first rubber wheel 22 and the second rubber wheel 23 are perpendicular to each other. The double-cylinder structure is adopted to control the movement of the lifting frame 2, improving the stability of the transmission structure. The perpendicularity of the lifting frame 2 during movement is maintained by the first rubber wheel 22 and the second rubber wheel 23.

[0029] In this embodiment, adapter plates 24 and fixing blocks 25 are provided at both ends of the lifting frame 2. The fixing blocks 25 are parallel to the lifting frame 2 through the adapter plates 24. The fixing blocks 25 are provided with long holes for connecting the sprockets 5.

At this time, due to the action of gravity, the fixing frame 75 is located below the floating column 73, and the fixing frame 75 tightly presses the proximity switch 10. After the next tire is conveyed to the designated position, the driving cylinder 3 controls the tire to move downward. The grabbed tire receives a supporting force. At this time, the tire drives the fixing frame 75 to move upward slightly, and the fixing frame 75 moves away from the proximity switch 10. After receiving the instruction from the proximity switch 10, the lifting frame 2 stops moving downward, the side clamping arm 7 releases the tire, the lifting frame 2 continues to move downward, and the side clamping arm 7 grabs and moves upward the stacked tire group again. Repeat the above actions to stack the tires.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
