A reversing conveyor system

Abstract

The application discloses a reversing conveying system, which comprises a first conveying line and a transfer trolley. The first conveying line is provided with a lower recess. The lower recess is provided with a transition conveying component, a lifting mechanism for driving the transition conveying component to lift and fall, and a first transfer track for the transfer trolley to move on. The first transfer track is arranged perpendicularly to the first conveying line. Initially, the material is conveyed along the first conveying line. The transition conveying component is in a high position. The transition conveying component cooperates with the first conveying line, so that the material can smoothly cross the lower recess. After the material is conveyed to the position, the transition conveying component falls to a low position to leave space. The transfer trolley moves along the first transfer track to the lower recess. A jacking component jacks the material upward to separate the material from the first conveying line and the transition conveying component. After the jacking is completed, the transfer trolley moves along the first transfer track to complete the reversing. The overall structure is compact, occupies less space and runs smoothly.

Description

Technical Field

[0001] This invention relates to the field of conveyor lines, and more particularly to a reversing conveyor system. Background Technology

[0002] Due to limitations such as production space, a conveyor line can hardly transport goods in only one direction; it generally needs to switch directions. Currently, the commonly used switching methods are mainly as follows:

[0003] 1) Cross conveying: It sets up mutually perpendicular horizontal and vertical conveying lines, and switches the conveying direction by changing the horizontal and vertical conveying height. The structure is relatively complex and occupies a large vertical space.

[0004] 2) Turning conveyor: The conveyor line achieves reversal by continuous and gentle bends. The structure is relatively complex and the cost is high. The reversal of the conveyor line requires a long setup.

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

[0006] 4) Lifting-type transfer: The lifting component lifts the material from the conveyor line and then moves it horizontally to another conveyor line. This requires the use of the lifting component, which increases the cost. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a reversing conveyor system that is compact in structure, occupies little space, and operates smoothly.

The overall structure is compact, occupies little space, and operates smoothly. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figure 1 , Figures 5 to 10As shown, the reversing conveying system of this embodiment includes a first conveyor line 1 and a transfer vehicle 6. The first conveyor line 1 has a recessed portion 2, and the recessed portion 2 has a transition conveying component 4, a lifting mechanism 5 for driving the transition conveying component 4 to rise and fall, and a first transfer track 61 for the transfer vehicle 6 to travel on. The first transfer track 61 is arranged perpendicular to the first conveyor line 1, and the transfer vehicle 6 has a lifting component 62. In this embodiment, both the first conveyor line 1 and the transition conveying component 4 are conveyed using rollers. Of course, in other embodiments, the first conveyor line 1 and the transition conveying component 4 can also be conveyed using belts, rollers, etc.

[0039] In this embodiment of the reversing conveying system, initially, the material is conveyed from left to right along the first conveyor line 1, and the transition conveyor component 4 is in a high position. The transition conveyor component 4 cooperates with the first conveyor line 1 to allow the material to smoothly cross the recess 2. After the material is conveyed into place, the transition conveyor component 4 descends to a low position to make room. The transfer vehicle 6 moves along the first transfer track 61 to the recess 2, and the lifting component 62 lifts the material upward to separate it from the first conveyor line 1 and the transition conveyor component 4. The structure is simple and effective. Of course, in other embodiments, the transfer vehicle 6 can also separate the material from the first conveyor line 1 and the transition conveyor component 4 by means of hoisting, etc., to facilitate subsequent transfer. After being lifted into place, the transfer vehicle 6 drives the material to move back and forth along the first transfer track 61 to complete the reversing conveying. The overall structure is compact, occupies little space, and operates smoothly.

[0040] Furthermore, in this embodiment, the lifting mechanism 5 includes a connecting arm 51 and a lifting drive 52 for driving the connecting arm 51 to swing up and down. One end of the connecting arm 51 is rotatably connected to the first conveyor line 1, and the transition conveying component 4 is disposed at the other end of the connecting arm 51. When the transition conveying component 4 needs to be raised or lowered, the lifting drive 52 drives the connecting arm 51 to swing up and down, which is simple and effective. Of course, in other embodiments, the lifting drive 52 can also be used to drive the connecting arm 51 to move up and down to achieve lifting.

[0041] Preferably, the lifting drive component 52 is a telescopic structure, with one end of the lifting drive component 52 hinged to the connecting arm 51 and the other end of the lifting drive component 52 hinged to the first conveyor line 1. This structure is simple and reliable. In this embodiment, the lifting drive component 52 is specifically a hydraulic cylinder. Of course, in other embodiments, the lifting drive component 52 can also be a pneumatic cylinder, an electric push rod, etc., which will not be elaborated further. The lifting component 62 can also be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0042] See details Figure 1In this embodiment, multiple first conveyor lines 1 are arranged in parallel. The first transfer tracks 61 of two adjacent first conveyor lines 1 are aligned and connected by a transition track 63. The transfer vehicle 6 moves the material back and forth along the first transfer track 61. With the help of the transition track 63, it can reach the first transfer track 61 of the adjacent first conveyor line 1. After it is in place, the lifting component 62 lowers the material onto the first conveyor line 1, completing the transfer of material between two adjacent first conveyor lines 1. The structure is simple and effective. Then the transfer vehicle 6 can return to the transition track 63, and the transition conveying component 4 returns to the high position, which can transport the material left and right along the first conveyor line 1. Since the first transfer tracks 61 of two adjacent first conveyor lines 1 are aligned and connected by the transition track 63, the transfer vehicle 6 can be simplified, eliminating the need for a double-layer structure.

[0043] Furthermore, in this embodiment, the first conveyor line 1 is provided with multiple recesses 2 along its length, and each transition track 63 is provided with a transfer vehicle 6, so that materials at different positions on two adjacent first conveyor lines 1 can be transferred simultaneously without interfering with each other, making it more convenient to use and more efficient.

[0044] Example 2

[0045] like Figures 2 to 11 As shown, another embodiment of the reversing conveyor system of this embodiment is largely the same as that of the embodiment, except that:

[0046] In this embodiment, multiple first conveyor lines 1 are provided and arranged in parallel. Multiple recesses 2 are provided along the length direction of the first conveyor lines 1, and the first transfer tracks 61 of two adjacent first conveyor lines 1 are staggered (i.e. no longer aligned). A transition track 63 is provided between two adjacent first conveyor lines 1. The first conveyor lines 1 and the transition track 63 are arranged in parallel. The transfer vehicle 6 includes a first transfer vehicle 64 provided on the transition track 63, a second transfer track 65 provided on the first transfer vehicle 64, and a second transfer vehicle 66 provided on the second transfer track 65. The second transfer track 65 is arranged in parallel with the first transfer track 61, and the lifting component 62 is provided on the second transfer vehicle 66. The first transfer vehicle 64 can drive the second transfer track 65, the second transfer vehicle 66, and other components to move along the transition track 63. When the second transfer track 65 is aligned with any first transfer track 61 on any first conveyor line 1, the second transfer vehicle 66 can move from the second transfer track 65 to the first transfer track 61 (and vice versa). Subsequently, materials can be lifted or lowered, making it convenient and flexible to use. Compared to Embodiment 1, since the transfer vehicle 6 needs to move along the transition track 63 on one hand and to the first transfer track 61 on the first conveyor line 1 on the other, the transfer vehicle 6 is configured as a double-layer structure to meet the requirements.

[0047] Example 3

[0048] like Figures 3 to 11 As shown, another embodiment of the reversing conveyor system of this example is presented. The reversing conveyor system of this example is largely the same as that of Examples 1 and 2, except that:

[0049] In this embodiment, the reversing conveying system also includes a second conveying line, warehouse or shelf 7 arranged perpendicular to the first conveying line 1, and a transition track 63 between the second conveying line, warehouse or shelf 7 and the first conveying line 1. Preferably, the second conveying line, warehouse or shelf 7 is provided with multiple parts and distributed along the length direction of the transition track 63. The first conveying line 1 is provided with multiple recesses 2 along the length direction (i.e., multiple first transfer tracks 61, which are aligned with a second conveying line, warehouse or shelf 7 to further improve conveying efficiency). The transition track 63 is arranged parallel to the first conveying line 1. The transfer vehicle 6 includes a first transfer vehicle 64 provided on the transition track 63, a second transfer track 65 provided on the first transfer vehicle 64, and a second transfer vehicle 66 provided on the second transfer track 65. The second transfer track 65 is arranged parallel to the first transfer track 61. The lifting component 62 is provided on the second transfer vehicle 66. Referring to Embodiment 2, the first transfer vehicle 64 can drive the second transfer track 65, the second transfer vehicle 66, and other components to move along the transition track 63. When the second transfer track 65 aligns with any of the first transfer tracks 61 on the first conveyor line 1, the second transfer vehicle 66 can move from the second transfer track 65 to the first transfer track 61 (and vice versa). Subsequently, materials can be lifted, transferred, and lowered onto any second conveyor line, warehouse, or shelf 7, making it convenient and flexible to use. Compared to Embodiment 1, since the transfer vehicle 6 needs to move along the transition track 63 on one hand and to the first transfer track 61 on the first conveyor line 1 on the other hand, the transfer vehicle 6 is configured with a double-layer structure to meet the requirements.

[0050] Furthermore, in this embodiment, the second conveyor line, warehouse, or shelf 7 is provided with a third transfer track 71 along its length. When the second transfer track 65 is aligned with any of the third transfer tracks 71 on the second conveyor line, warehouse, or shelf 7, the second transfer vehicle 66 can move from the second transfer track 65 to the third transfer track 71 (and vice versa), thereby placing materials down to different positions on the second conveyor line, warehouse, or shelf 7, or retrieving materials from different positions on the second conveyor line, warehouse, or shelf 7.

[0051] Example 4

[0052] like Figures 4 to 11As shown, another embodiment of the reversing conveyor system in this example is presented. This reversing conveyor system is generally the same as that in Examples 1 and 3, except that:

[0053] In this embodiment, the reversing conveyor system further includes a second conveyor line, warehouse, or shelf 7 arranged perpendicularly to the first conveyor line 1. A transition track 63 is provided between the second conveyor line, warehouse, or shelf 7 and the first conveyor line 1. The transition track 63 is arranged parallel to the first conveyor line 1. A third transfer track 71 is provided along the length of the second conveyor line, warehouse, or shelf 7, and the first transfer track 61 is aligned with the third transfer track 71. When there is only one second conveyor line, warehouse, or shelf 7, the transfer vehicle 6 can adopt a single-layer structure. When there are multiple second conveyor lines, warehouses, or shelves 7, the transfer vehicle 6 can be configured as a double-layer structure.

[0054] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
