Description

Technical Field

[0001] The present invention relates to the technical field of intelligent conveying systems, and particularly to a single-belt S-shaped working surface automatic switching intelligent conveying system. Background Art

[0002] With the development of intelligent manufacturing, conveyors are gradually becoming more intelligent and unmanned. In order to meet the conveying requirements of different materials, double-layer belt conveyors have been developed. However, in existing double-layer conveyors, two independently arranged belts are used. Even though the function of switching from a double-layer working surface to a single-layer working surface is achieved, the two belts are still independent. The connection position of the belts cannot be made continuous, and the continuity of the belts cannot be guaranteed, resulting in problems such as material scattering and leakage. Due to the high-speed and long-term operation of the conveyor, the scattered materials accumulate more and more, and it is necessary to stop the machine for cleaning. This still requires manual intervention and cannot be completely free from manual intervention, so true unmanned operation cannot be achieved. Summary of the Invention

[0003] In view of the above defects, the present invention provides a single-belt S-shaped working surface automatic switching intelligent conveying system, including: a first roller, a second roller, a third roller, a fourth roller, a fifth roller, a head device, a tail device, and a belt. The head device and the tail device are located at both ends, and the bottom of the head device is movable relative to the roadway ground. The first roller and the second roller are arranged on the head device, and the head device is provided with a vertical sliding mechanism for connecting the first roller to move the first roller from the upper part of the head device to the lower part along the vertical sliding mechanism. The third roller, the fourth roller, and the fifth roller are all arranged on the tail device. The third roller moves downward relative to the tail device, and a movable frame body is further arranged on the tail device. The movable frame body is rotatably connected to the tail device, and the fourth roller and the fifth roller are arranged on the movable frame body. The belt is a loop-shaped closed belt, and the belt is sleeved on the five rollers in an S shape. The first roller, the second roller, the fourth roller, and the fifth roller are located inside the belt. A lower-layer slide rail is further arranged between the tail device and the second roller. The right end of the lower-layer slide rail is connected to the tail device, and the left end is arranged on the ground through a plurality of support frames. The second roller moves relatively on the lower-layer slide rail. The third roller is located outside the belt, and a traction mechanism is further arranged on the head device. One end of the traction mechanism is fixed to the head device, and the other end is connected to the second roller. The length of the traction mechanism changes with the change of the position of the second roller.

[0004] In the present invention, the downward movement of the first roller is achieved by the vertical sliding mechanism on the head device, and the downward movement of the second roller is achieved by the vertical sliding mechanism on the tail device. The downward movement of the first supporting mechanism (including the first supporting frame, the first track, the first upper roller, the first lower roller, and the first connecting piece) of the supporting tape connected to the head device is achieved by its own mechanism, and the second supporting mechanism (including the second supporting frame, the second track, the second upper roller, and the second lower roller) of the supporting tape connected to the tail device does not move downward, but is achieved by its own mechanism when moving to the right. The various mechanisms cooperate with each other without interfering with each other, thereby realizing the switching from the double-layer tape to the single-layer tape.

[0005] The support frame drives the rollers, rollers and adhesive tape to switch from double-layer to single-layer, which is automatically realized by the mechanical structure of the present invention, thus fully realizing unmanned and automated operation. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0022] Refer to Figures 1-7, the present invention provides a single-tape S-shaped working surface automatic switching intelligent conveying system, including: a first roller 10, a second roller 20, a third roller 30, a fourth roller 40, a fifth roller 50, a head device 60, a tail device 70, and a tape 80. The head device 60 and the tail device 70 are located at both ends. The bottom of the head device 60 is movable relative to the roadway ground. The first roller 10 and the second roller 20 are arranged on the head device 60. The head device 60 is provided with a vertical sliding mechanism (this is a conventional design. For example, small gears are arranged at both ends of the shaft of the first roller 10, and vertical tracks or racks meshing with the small gears are arranged on the frame of the head device 60) for connecting the first roller 10, so that the first roller 10 moves from the upper part to the lower part of the head device 60 along the vertical sliding mechanism. The third roller 30, the fourth roller 40, and the fifth roller 50 are all arranged on the tail device 70. The third roller 30 moves downward relative to the tail device 70 (similar to the structure of the first roller 10 and the head device 60, a vertical sliding mechanism is provided). An active frame 76 is also arranged on the tail device 70. The active frame 76 is rotatably connected to the tail device 70, and the fourth roller 40 and the fifth roller 50 are arranged on the active frame 76. The tape 80 is a loop-shaped closed tape, and the tape is sleeved on the five rollers in an S shape. The first roller 10, the second roller 20, the fourth roller 40, and the fifth roller 50 are located inside the tape 80. A lower-layer slide rail 721 is also arranged between the tail device 70 and the second roller 20. The right end of the lower-layer slide rail 721 is connected to the tail device 70, and the left end is arranged on the ground through a plurality of support frames. The second roller 20 moves relatively on the lower-layer slide rail 721 to realize the function of the second roller sliding to the right and towards the tail device, thereby realizing the compensation of the tape length to the first roller. The third roller 30 is located outside the tape. A traction mechanism 68 is also arranged on the head device 60. One end of the traction mechanism 68 is fixed to the head device 60, and the other end is connected to the second roller 20. The length of the traction mechanism 68 changes with the change of the position of the second roller 20.

[0023] Through the position setting of the five rollers, this solution realizes the change of the same closed tape from a double working surface to a single working surface, and this change adapts to the changes in the length and height of the roadway. The first roller 10 moves to the left and is pulled by an external mechanism on the left to move. For example, as the left excavation mechanism or mining mechanism moves, it can follow and adapt synchronously without a separate traction power. During the transformation process, the second roller 20 and the first roller 10 form mutual length compensation. The fourth roller 40 and the fifth roller 50 realize position transformation through the active frame 76 and are withdrawn from inside the tape, completely not affecting the original operation mode of the tape. The downward movement of the third roller 30 and the first roller 10 makes the tape return from two working surfaces to a horizontal and closed working surface. Each component cooperates with each other and does not interfere with each other.

[0024] The tape in the present invention is a loop-shaped closed tape. By winding, it is wound around five rollers. By setting the positions of the five rollers, the tape between the first roller 10 and the fourth roller 40 forms an upper working surface, and the tape between the second roller 20 and the fifth roller 50 forms a lower working surface. The third roller 30 serves as a redirecting roller. One tape forms a double working surface for receiving two different materials or transporting one material with double efficiency.

[0025] The process of changing from double-layer to single-layer is as follows: (1) As the head moves forward, the first roller 10 continuously moves to the left. As the conveying system of the present invention moves forward, its length will increase. Or when it is necessary to change to transporting one material, the head device 60 moves to the left, pulling the first roller 10 to move. The tail device 70 remains in place. Since the original length of the tape does not change, the second roller 20 is forced to be pulled by the tail device 70 and move to the right along the lower slide rail 721. The increase in the tape length when the first roller 10 moves to the left is compensated by the tape length vacated by the second roller 20 moving to the right, keeping the total length of the tape unchanged. As Figure 1 .

[0026] (2) As the first roller 10 continuously moves to the left, the second roller 20 moves to the first preset position, which is located on the right side of the third roller 30. The second roller 20 vacates space for the third roller 30. As Figure 2 .

[0027] (3) Then, the fourth roller 40 and the fifth roller 50 rotate to the right around the movable frame 76, so that the fourth roller 40 and the fifth roller 50 get out of the closed tape interior and no longer support the tape. As Figure 3 .

[0028] (4) As the first roller 10 continuously moves to the left, the second roller 20 continues to move to the right and reaches the second preset position, that is, the fixed position of the tail device 70, to support the tape; at the same time, the third roller 30 moves down to the bottommost position, getting rid of and detaching from the tape, and the first roller 10 moves down to the lower part of the head device 60, thus forming a state where the leftmost and rightmost ends of the tape are supported by the first roller 10 and the second roller 20 respectively. At this time, the working surface of the tape becomes a single working surface, which is the upper surface of the tape between the first roller 10 and the second roller 20. As Figure 4 .

[0029] Furthermore, when the second roller 20 moves to the right, the traction mechanism maintains an appropriate tension to keep the tape stretched and not loose, and can also ensure the slack of the second roller 20 moving to the right. When the first roller 10 moves to the left, this tension counteracts the rightward pulling force of the tape.

[0030] Furthermore, the traction mechanism 68 is a steel wire rope.

[0031] Furthermore, the movable frame 76 includes a hinge rod 77 and a connecting rod 78. One end of the hinge rod 77 is fixedly connected to the column of the tail device 70, and the other end is hinged to the connecting rod 78. There are two connecting rods 78, which are respectively used to connect the fourth roller 40 and the fifth roller 50.

[0032] Furthermore, a crawler group is provided at the bottom of the head device 60 for controlling the head device 60 to move along the roadway floor.

[0033] Furthermore, a number of support mechanisms are also provided between the head device 60 and the tail device 70 for supporting the belt.

[0034] See Figures 8-19 , furthermore, the support mechanism includes a second support frame 71, a second track 72, a second upper idler 73, and a second lower idler 74. The second support frame 71 is arranged on the roadway floor between the head device 60 and the tail device 70. There are two second tracks 72, which are respectively arranged inside the second support frame 71. The second track 72 is slidably connected to the second support frame 71, so that the second track 72 moves relative to the second roller; the right end of the second track 72 is connected to the tail device 70. The second upper idler 73 and the second lower idler 74 are arranged above and below the second track 72 and are both connected to the second track 72. The upper surfaces of the second upper idler 73 and the second lower idler 74 are used to support the belt and provide a rolling support surface for the movement of the belt; the lower layer slide rail 721 is fixedly connected to the second track 72 as a whole, and the lower layer slide rail 721 is used to support the rolling of the second roller 20, and the second roller 20 does not directly contact the second track 72; one end of the second upper idler 73 is hinged to the second track 72, and the other end is movably fixed to the second track 72, so that the other end of the second upper idler 73 can be separated from the second track 72 and rotate around the hinge to a position avoiding the belt. For example, rotate more than 90 degrees to a position parallel to the second track 72, so as not to be inside the belt, and the belt is supported by the second roller 20. The hinge can adopt a conventional structure, such as a hinge shaft 731, a bushing, etc.

[0035] Furthermore, the support mechanism further includes a second connecting member 75. The second connecting member 75 includes a second roller and a second connecting rod. One end of the second connecting rod is arranged inside the second support frame 71 and is connected to the second support frame 71, and the other end is connected to the second roller. The second roller rotates relative to the second connecting rod. A transverse chute is also opened on the outer side surface of the second track 72, and the second roller is arranged in the transverse chute, so that the second track 72 moves relative to the second roller; in this solution, the second connecting member 75 can also be an integral component and is connected between the second track 72 and the second support frame 71.

[0036] The second roller 20 does not directly contact the second track 72, but only contacts the lower slide rail 721 and moves along the lower slide rail 721. If the tail device 70 pulls the second track 72 to move relative to the second support frame 71, the lateral chute and the second connecting member 75 provide structural support for relative movement. When the head device 60 moves to the left, the belt that gives way to the left forces the second roller 20 to move to the right. The second roller 20 slides to the right along the lower slide rail 721. At this time, since the second upper idler 73 is located inside the belt and in front of the movement of the second roller 20, the original positions of several second upper idlers 73 constitute an obstacle to the rightward movement of the second roller 20. Therefore, in an articulated manner, the other end of the second upper idler 73 is opened manually or by other means, and one end rotates to give way to one side, so that the belt pulls the second roller 20 to move to the right along the lower slide rail 721 to a preset position. After that, after the first roller 10 moves downward and the belt also moves downward, the second upper idler 73 is located in the middle position of the belt, and the second upper idler 73 rotates in the reverse direction, returns to its original position, and is connected to the second track 72 again, still carrying the operation of the belt.

[0037] During normal double-layer operation, the other end of the second upper idler 73 is fixed to the second track 72 in a conventional manner, so that the second upper idler 73 can be fixed and the belt can be carried without running out of position.

[0038] Furthermore, the support mechanism includes a number of first support frames 61, first tracks 62, first upper idlers 63, first lower idlers 64, and first connecting members 65; the first support frames 61 are arranged on the roadway ground, there are two first tracks 62, which are respectively arranged inside the first support frames 61 through the first connecting members 65, the left end of the first track 62 is connected to the head device 60, the first upper idlers 63 and the first lower idlers 64 are arranged above and below the first track 62 and are both connected to the first track 62. The upper surfaces of the first upper idlers 63 and the first lower idlers 64 are used to support the first upper layer belt and the first lower layer belt, providing a rolling support surface for the movement of the belt; the first connecting member 65 includes a first roller 66 and a first connecting rod 67. One end of the first connecting rod 67 is arranged inside the first support frame 61 and is connected to the first support frame 61, and the other end is connected to the first roller 66. The first roller 66 rotates relative to the first connecting rod 67. A lateral chute is also opened on the outer side surface of the first track 62, and the first roller 66 is arranged in the lateral chute, so that the first track 62 moves relative to the first roller 66; a vertical chute is also opened on the inner side wall of the first support frame 61, and a lifting mechanism is arranged in the vertical chute. The bottom of the lifting mechanism is fixed inside the first support frame 61, and the top is connected to the first connecting rod 67. The lifting mechanism has the function of moving up and down along the vertical chute, thereby driving the first connecting rod 67 to move downward along the vertical chute.

[0039] Furthermore, the lifting mechanism is an oil cylinder or a cylinder.

[0040] When the double-sided tape is working, the lifting mechanism in the first support frame always maintains the jacking force to support the first track above the second track. When the first track or the second track is pulled to a predetermined position, the lifting mechanism removes the jacking force, and the first track and the structures thereon are pulled to move downward along the vertical chute. When reaching the predetermined position, such as being flush with the second track, the lifting mechanism stops operating, realizing the combination of the upper tape and the lower tape.

[0041] When the original two-layer structure is to be changed into a one-layer structure by the components of the present invention, the original length of the tape does not change, but only the working surface for carrying materials is deformed from the original two working surfaces into a flat working surface.

[0042] The embodiments of the present solution have been described in detail above in conjunction with the accompanying drawings. However, the present solution is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the scope of knowledge possessed by those of ordinary skill in the art.
