[0004] 2) Turning conveying: The conveyor line is bent continuously and gently to achieve the final reversal. The structure is relatively complex and the cost is high. The reversal of the conveyor line needs to be set longer.

[0005] 3) Transfer vehicle with receiving conveying: The material is transferred from the conveying line to the transfer vehicle through the conveying mechanism on the transfer vehicle, and then moved to another conveying line through the reversing of the transfer vehicle. The efficiency of completing the reversing is low and the space required is large;

[0006] 4) Lifting transfer: The lifting components lift the materials from the conveyor line, and then move them horizontally to another conveyor line. Since the lifting components are needed, additional costs are added. Utility Model Content

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Figures 1 to 6 An embodiment of the reversing conveying device of the utility model is shown. The reversing conveying device of this embodiment includes a conveying bracket 1. The conveying bracket 1 is provided with a lower concave portion 2 and a first conveying member 3 located on both sides of the lower concave portion 2. The lower concave portion 2 is provided with a second conveying member 4 and a lifting mechanism 5 for driving the second conveying member 4 to rise and fall. In this embodiment, the first conveying member 3 and the second conveying member 4 are both conveying rollers. Of course, in other embodiments, the first conveying member 3 and the second conveying member 4 can also be conveying belts, conveying rollers, etc.

[0033] In the reversing conveying device of this embodiment, when the material is conveyed along the initial direction (left and right direction in this embodiment), the second conveying member 4 is in a high position, and the second conveying member 4 cooperates with the first conveying member 3 so that the material can smoothly cross the lower recess 2. After the material is conveyed in place, the second conveying member 4 drops to a low position to make room, and the transfer vehicle 6 and other components that can complete the reversal can move to the lower recess 2, and then drive the material to reverse (convey along the vertical direction of the paper or the front and back direction). The overall structure is compact and occupies less space. It should be noted that in this embodiment, the material is a prefabricated component mold, and two groups of first conveying members 3 are respectively arranged on the left and right sides of the second conveying member 4. Of course, in other embodiments, as the size and shape of the material change, the number of groups of the first conveying member 3 and the second conveying member 4 can also be appropriately adjusted.

[0034] Furthermore, in this embodiment, the lifting mechanism 5 includes a connecting arm 51 and a lifting driving member 52 for driving the connecting arm 51 to swing up and down, one end of the connecting arm 51 is rotatably connected to the conveying bracket 1, and the second conveying member 4 is arranged at the other end of the connecting arm 51. When the second conveying member 4 needs to be lifted, the lifting driving member 52 drives the connecting arm 51 to swing up and down, and the structure is simple and effective. Of course, in other embodiments, the lifting driving member 52 can also be used to drive the connecting arm 51 to move up and down to achieve lifting.

[0035] Furthermore, in this embodiment, the conveying bracket 1 is provided with a first transmission member 12, the second conveying member 4 is coaxially provided with a second transmission member 41, one end of the connecting arm 51 is connected to the rotating shaft 11, the rotating shaft 11 is rotatably provided on the conveying bracket 1, the first transmission member 12 coincides with the axis of the rotating shaft 11, and the second transmission member 41 is connected to the first transmission member 12. Among them, the first transmission member 12 and the second transmission member 41 can be connected by a sprocket through a chain; or the first transmission member 12 and the second transmission member 41 can also be a pulley and connected by a synchronous belt. The connecting arm 51 is connected to the conveying bracket 1 through the rotating shaft 11, and can swing up and down relative to the conveying bracket 1 under the drive of the lifting drive member 52. Since the first transmission member 12 coincides with the axis of the rotating shaft 11, the second conveying member 4 can still realize the transmission of conveying power even if it rotates to a high position, and then the material is transported to the position along the initial conveying direction, and the structure is reasonable and effective. Of course, in other embodiments, the second conveying member 4 can also be driven by a cylinder, an oil cylinder, etc. to achieve linear lifting. At the same time, the second conveying member 4 is separately provided with an electric motor, a hydraulic motor, etc. to provide conveying power. The disadvantage is that the number of conveying drive components is increased, the corresponding structure becomes complicated, and the cost is increased.

[0036] Furthermore, in this embodiment, a conveying drive member 7 (such as a motor, a hydraulic motor, etc.) is provided on the conveying bracket 1, and a third transmission member 31 (such as a sprocket, a pulley, etc.) is coaxially provided on the first conveying member 3, and the conveying drive member 7 is connected to the first transmission member 12, and the third transmission member 31 is connected to the first transmission member 12. When conveying materials along the initial direction, the conveying drive member 7 drives the first transmission member 12 to rotate, and then drives the second transmission member 41 and the third transmission member 31 to rotate through a chain, a synchronous belt, etc., and finally realizes the rotation of the second conveying member 4 and the first conveying member 3. The structure is reasonable and effective, which can save the number of conveying drive members, simplify the structure, and reduce costs.

[0037] As a preferred embodiment, the lifting drive member 52 is a telescopic structure, one end of the lifting drive member 52 is hinged to the connecting arm 51, and the other end of the lifting drive member 52 is hinged to the conveying bracket 1, and the structure is simple and reliable.

[0038] In this embodiment, the lifting drive member 52 is an oil cylinder. Of course, in other embodiments, the lifting drive member 52 can also be a gas cylinder, an electric push rod, etc., which will not be described in detail.

[0039] Furthermore, in this embodiment, the reversing conveying device further includes a transfer vehicle 6, and the lower concave portion 2 is provided with a transfer track 61 for the transfer vehicle 6 to travel, and the length direction of the transfer track 61 is perpendicular to the conveying direction of the first conveying member 3. The second conveying member 4 cooperates with the first conveying member 3 to convey the material in the left and right directions, so that the material smoothly crosses the lower concave portion 2 and is in place, and then the second conveying member 4 is lowered to a low position to make room, and then the transfer vehicle 6 moves along the transfer track 61 to the lower concave portion 2, and at this time, the transfer vehicle 6 is located below the material, which is convenient for driving the material to be reversibly conveyed along the transfer track 61.

[0040] Furthermore, in this embodiment, a lifting component 62 is provided on the transfer vehicle 6. After the transfer vehicle 6 moves to below the material, the lifting component 62 lifts the material upward and separates it from the first conveying member 3 and the second conveying member 4. After the lifting is in place, the transfer vehicle 6 drives the material to move along the transfer track 61 to complete the reversing conveying.

[0041] Furthermore, in this embodiment, a telescopic leg 13 is provided on the conveying bracket 1. By extending and retracting the telescopic leg 13, the height of the conveying bracket 1 and the first conveying member 3 and the second conveying member 4 thereon can be adjusted, and the adaptability of the device can be improved. Specifically, the telescopic leg 13 can adopt a multi-stage sleeve structure, and can be extended and retracted by driving an oil cylinder, an air cylinder, etc.; or can be extended and retracted by a screw rod cooperating with a nut on the screw rod.
