Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, use of directional terms such as "upper, lower, left, and right" generally means that they are defined with reference to the drawing plane directions of the corresponding drawings. "inner and outer" refer to the inner and outer of the respective component profiles. The terms "first," "second," and the like are used herein to distinguish one element from another, and are not intended to be sequential or important. In addition, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements, unless otherwise indicated.

The present disclosure provides a conveying system including a plurality of conveying mechanisms 100 arranged at intervals along a conveying direction, and for convenience of description, only two conveying mechanisms 100 are shown in fig. 1 and 2, it should be understood that a greater number of conveying mechanisms 100 may be provided according to actual needs, such as the length of a production line. Each of the transfer mechanisms 100 includes a transfer platform 1 extending in the transfer direction and a drive motor 2 for driving the transfer platform 1 to move in the transfer direction, and a transmission device 3 for transmitting a motive power is provided between the transfer platform 1 and the drive motor 2. Through the technical scheme, the transmission mechanism is different from the existing mode that the whole transmission line is driven by only one driving motor, and each transmission mechanism is driven by the independent driving motor, so that the power and the torque required by each driving motor according to the load are correspondingly reduced, the problem of high power consumption caused by high power and large torque is solved, and meanwhile, the running speed and the transmission efficiency can be improved.

The transport platform 1 is used for carrying objects to be transported, for example for carrying vehicles to be welded on vehicle production. The extending direction of the conveying platform 1 can be selectively set according to actual needs, for example, in a repair welding production line, which is a generally straight production line, so that the extending direction of the conveying platform 1 can be a straight direction. There may be a certain gap between the individual transfer platforms 1 as long as the presence of the gap does not affect the normal coherent transfer of the objects transported by the belt thereon.

The driving motor 2 may be a rotary motor, and the transmission device 3 is used for converting the rotary motion generated by the driving motor 2 into the linear motion of the conveying platform 1. According to an embodiment of the present disclosure, with continued reference to fig. 1 and 2, the transmission 3 may comprise a gearbox 31, a motor coupling 32 arranged between the drive motor 2 and the gearbox 31, and a gearbox coupling 33 arranged between the gearbox 31 and the transfer platform 1. The gearbox 31 can here be any of the mechanical transmission fields used for changing the rotational speed and torque transmission. It should be noted that, in order to output the torque of the driving motor 2 to the transmission platform 1, it is not limited to the gearbox 31, and other conventional power transmission methods, such as a turbine worm mechanism arranged reasonably, can also achieve the effect of power transmission.

Since the conveying system of the present disclosure may be regarded as dividing the whole conveying line into multiple sections, in order to ensure that each section can operate synchronously, referring to fig. 4, the conveying system may further include a synchronous controller 5, and the synchronous controller 5 is respectively connected to the driving motor 2 of each conveying mechanism 100, so that the conveying platforms 1 can operate synchronously by the cooperative control of the driving motors 2. Further, the transport system may further include a monitoring device 6 for monitoring an operation position and an operation state of each transport mechanism 100, and the monitoring device 6 is connected to the synchronization controller 5 and the transport mechanism 100, respectively.

The operating state includes start-up, stop, acceleration, and deceleration of the drive motor 2. The monitoring device 6 monitors the running state of each conveying mechanism 100 and feeds the monitoring result back to the synchronous controller 5 in real time, and in response to the monitoring result, the synchronous controller 5 can ensure the synchronous running of each conveying mechanism 100 in real time, so that the running stability of the conveying system is improved. In addition, the conveying system may further include a display device 7 for displaying the operation position of each conveying mechanism 100, so that an operator can grasp the operation position of the conveying mechanism 100 in real time. In order to obtain the operating position of the transfer mechanism 100, a position sensor (not shown in the drawings) may be provided on each transfer mechanism 100.

In the prior art, because the whole transmission line is driven by a single motor, when the single motor or a transmission device fails, production can only be stopped and maintained. In order to solve the above technical problem, on the basis of the above conveying system, the two adjacent conveying platforms 1 may be respectively provided with a connecting portion 11, and the conveying system further includes a connecting assembly 4 for cooperating with the connecting portion 11 to detachably connect the two adjacent conveying platforms 1 into a whole. Thus, even if any one of the drive motors 2 fails, the operation of the entire conveyance system is not affected.

Specifically, when a certain driving motor 2 or the gearbox 31 has a fault, each conveying platform 1 can be adjusted to the original point position, and the original point position can be set manually. The system is then de-energized and the transmission 3 in which the malfunction occurred is removed, for example the gearbox coupling 33 can be removed, so that the transmission 3 is disconnected from the transport platform 1. And then two adjacent conveying platforms 1 are connected into a whole through a connecting assembly 4. Parameters of the connected drive motor 2 are modified as required, including extending acceleration time, extending deceleration time, decreasing top speed, etc. And after the power is on, parameters are transmitted, and the power supply of the synchronous controller 5 is disconnected.

According to an embodiment of the present disclosure, as shown in fig. 3, the connection part 11 is configured as a connection hole, the connection assembly 4 includes a connection pin 42 and a connection plate 41 for being erected between the adjacent two transfer platforms 1, and the connection pin 42 respectively passes through the connection plate 41 and the connection hole to connect the adjacent two transfer platforms 1 as one body. Optionally, the connection plate 41 comprises an upper connection plate 411 arranged on the upper surface of the conveying platform 1 and a lower connection plate 412 arranged on the lower surface of the conveying platform 1, so as to improve the connection strength. It should be understood that any structure and method capable of detachably connecting two adjacent conveying platforms 1 into a whole can be applied to the present disclosure, for example, a manner of a buckle or a hook, and will not be described herein again.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
