Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a single-drive staggered conveying device. Background Technology

[0002] In the field of material conveying technology, in order to improve conveying efficiency and save space, a double-layer conveying layout is often adopted, which means arranging two conveyor lines in parallel, one above the other, to achieve synchronous or alternating material conveying.

[0003] Currently, common double-layer conveyor systems typically employ an independent drive design, meaning each of the upper and lower conveyor lines is equipped with a complete drive system, including independent motors, transmission mechanisms, and control units. While this design enables independent operation of the two conveyor lines, it also has significant drawbacks: First, the dual drive mechanisms result in a complex equipment structure and a large number of components, occupying considerable space and increasing the difficulty of installation and maintenance. Second, the redundant power components directly increase manufacturing costs, and the increased energy consumption also raises long-term operating costs. Furthermore, the synchronization adjustment between the two conveyor lines relies on the coordination of their respective control units, making debugging difficult and prone to material accumulation or discontinuous conveying due to control errors, affecting the overall system's stability and efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that the existing technology requires a complete drive system for each of the upper and lower conveyor lines, which leads to complex equipment structure and increased cost, a single-drive staggered conveyor device is provided.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a single-drive interleaved conveying device, comprising: First conveyor platform; The second conveying platform is located above the first conveying platform; The first lead screw and nut pair is used to drive the first conveyor platform to perform linear reciprocating motion. The second lead screw and nut pair is used to drive the second conveying platform to perform linear reciprocating motion, and the second lead screw of the second lead screw and nut pair rotates in opposite directions to the first lead screw of the first lead screw and nut pair. And a power mechanism, which is synchronously connected to the input ends of the first lead screw and the second lead screw to drive them to rotate synchronously.

[0006] Furthermore, the power mechanism includes a rotary power source, a driving pulley connected to the rotary power source, a first driven pulley connected to the first lead screw, a second driven pulley connected to the second lead screw, and a synchronous belt wound around the driving pulley, the first driven pulley, and the second driven pulley.

[0007] Furthermore, it also includes: The first guiding mechanism includes a first slider installed at the bottom of the first conveying platform and a first slide rail that cooperates with the first slider. The second guide mechanism includes a second slider installed at the bottom of the second conveying platform and a second slide rail that cooperates with the second slider.

[0008] Furthermore, the extension length of the second conveying platform is greater than that of the first conveying platform, and the bottom of the second conveying platform is supported by a lifting block.

[0009] Furthermore, the lifting block has a clearance surface for the passage of the first conveying platform.

[0010] Furthermore, the first lead screw and the second lead screw are arranged side by side in a transverse direction, and the first slide rail is located inside the first lead screw, while the second slide rail is located outside the second lead screw.

[0011] Furthermore, both the first and second conveying platforms are equipped with positioning blocks for positioning the conveying fixture.

[0012] Furthermore, the power mechanism has two sets, which are distributed on both sides of the first conveying platform and the second conveying platform.

[0013] The beneficial effects of this utility model are as follows: This utility model uses the same power mechanism to drive the first conveyor platform and the second conveyor platform to move in opposite directions at all times, so that when one conveyor platform is delivering goods, the other conveyor platform is picking up goods, thereby saving loading and unloading time and greatly improving conveying efficiency.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components, orientations, and references (e.g., up, down, left, right, etc.) relevant to the present invention and are intended only to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0017] like Figures 1-4 As shown, a single-drive staggered conveyor device includes: First conveyor platform 1; The second conveying platform 2 is located above the first conveying platform 1. That is, the second conveying line formed by the second conveying platform 2 is offset from the first conveying line formed by the first conveying platform 1 in the height direction, so that the two can move synchronously without interfering with each other. The first lead screw and nut assembly 3 is used to drive the first conveying platform 1 to perform linear reciprocating motion. The second lead screw and nut assembly 4 is used to drive the second conveying platform 2 to perform linear reciprocating motion, and the second lead screw of the second lead screw and nut assembly 4 rotates in opposite directions to the first lead screw of the first lead screw and nut assembly 3. The power mechanism 5 is synchronously connected to the input ends of the first and second lead screws to drive them to rotate synchronously. Since the first and second lead screws rotate in opposite directions, during their synchronous rotation, the first conveying platform 1 and the second conveying platform 2 always move in opposite directions (towards or away from each other). When the first conveying platform 1 moves from the starting point to the ending point to deliver goods, the second conveying platform 2 moves from the ending point to the starting point to return and retrieve goods, and vice versa. The most time-consuming part of the conveying process is loading and unloading. In this embodiment, the two conveying platforms perform loading and unloading operations at the same time, which greatly improves the conveying efficiency.

[0018] In this embodiment, the same power mechanism 5 is used to drive the first conveying platform 1 and the second conveying platform 2 to move in opposite directions at all times. This allows one conveying platform to deliver goods while the other conveying platform picks up goods, thereby saving loading and unloading time and greatly improving conveying efficiency. Furthermore, the single-drive mode formed by the same power mechanism 5 greatly simplifies the structure and saves costs.

[0019] In some examples, the power mechanism 5 includes a rotary power source 501, a drive pulley 502 connected to the rotary power source 501, a first driven pulley 503 connected to the first lead screw, a second driven pulley 504 connected to the second lead screw, and a synchronous belt 505 wound around the drive pulley 502, the first driven pulley 503, and the second driven pulley 504. The rotary power source 501 may be a motor. When the rotary power source 501 is started, the drive pulley 502 rotates, which drives the first driven pulley 503 and the second driven pulley 504 to rotate through the synchronous belt 505, thereby driving the first lead screw and the second lead screw to rotate synchronously, so that the first conveying platform 1 and the second conveying platform 2 move in opposite directions.

[0020] In some examples, it also includes: The first guiding mechanism includes a first slider installed at the bottom of the first conveying platform 1 and a first slide rail 6 that cooperates with the first slider. The first slider and the first slide rail 6 cooperate to guide the movement of the first conveying platform 1. The second guide mechanism includes a second slider installed at the bottom of the second conveying platform 2 and a second slide rail 7 that cooperates with the second slider. The second slider and the second slide rail 7 cooperate to guide the movement of the second conveying platform 2.

[0021] In some examples, the extension length of the second conveying platform 2 is greater than the extension length of the first conveying platform 1, and the bottom of the second conveying platform 2 is supported by a lifting block 8. The lifting block 8 can make the second conveying platform 2 higher than the first conveying platform 1. The lifting block 8 is arranged at the corner of the second conveying platform 2, so as not to hinder the movement of the first conveying platform 1.

[0022] In some examples, the lifting block 8 has a clearance surface 801 for the passage of the first conveying platform 1. In order to obtain a more stable support effect, the extension length of the lifting block 8 can be appropriately extended. The clearance slope on the lifting block 8 can allow the lifting block 8 to obtain a longer extension length without interfering with the movement of the first conveying platform 1. Preferably, the clearance surface 801 is an arc surface, and the arc surface protrudes in the direction of the second conveying platform 2.

[0023] In some examples, the first lead screw and the second lead screw are arranged side by side laterally, and the first slide rail 6 is located inside the first lead screw and the second slide rail 7 is located outside the second lead screw, thereby allowing the entire conveying device to be further compressed in height.

[0024] In some examples, both the first conveying platform 1 and the second conveying platform 2 are equipped with positioning blocks 10 for positioning the conveying fixture 9. There are multiple positioning blocks 10, and positioning spaces are formed between the multiple positioning blocks 10.

[0025] In some examples, the power mechanism 5 has two sets and is distributed on both sides of the first conveying platform 1 and the second conveying platform 2. The synchronous operation of the two sets of power mechanisms 5 can improve the stability of the movement of the first conveying platform 1 and the second conveying platform 2 and avoid situations such as tilting or jamming. In this embodiment, although there are two sets of power mechanisms 5, the two sets of power mechanisms 5 have the same function, rather than the two sets of power mechanisms 5 acting on the first conveying platform 1 and the second conveying platform 2 respectively. Therefore, it is still a single-drive mode.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
