[0030] With reference to Figure 1 , Figure 2 The embodiment of the present application provides a segmented control speed chain conveying device, which comprises a support assembly (not shown in the figure), a first speed chain conveying line 10 arranged on the support assembly and moving in a first direction, the first speed chain conveying line 10 comprising at least two first speed chain conveying sections 11 (three in the embodiment) arranged in sequence at the head and tail in the first direction, each first speed chain conveying section 11 comprising two groups of first speed chains 111 arranged in parallel, and a first driving motor assembly 20 located at the head and driving the two groups of first speed chains 111.

[0031] It should be noted that the lengths of the first speed chain 111 in at least two first speed chain conveying sections 11 can be the same or different. When the first speed chain conveying section 11 has multiple sections, the lengths of the first speed chain 111 in each section can be partially the same, partially different, completely the same, or completely different. The length of the speed chain can be adjusted according to the processing time of each station on the production line or the running speed of the speed chain. In the present embodiment, the first speed chain 111 has multiple sections, and the lengths of the sections are not completely the same.

[0032] Further, in the present embodiment, the first driving motor assembly 20 includes a first driving motor 21, a first driving wheel 22 driven by the first driving motor 21, a first driven wheel 24 connected to the first driving wheel 22 through a belt 23, and another first driven wheel (not shown in the figure) arranged side by side with the first driven wheel 24 and coaxially connected through a rotating shaft 25, and two groups of first speed chains 111 are respectively sleeved on the two first driven wheels 24. When the first driving motor 21 is working, it drives the first driving wheel 22 to rotate, and the first driving wheel 22 drives the first driven wheel 24 to rotate through the belt 23. The two first driven wheels 24 are coaxially connected through the rotating shaft 25, so that the two first driven wheels 24 rotate synchronously under the drive of the belt 23, and the two groups of first speed chains 111 are respectively closed-loop sleeved on the two first driven wheels 24, so that the two first driven wheels 24 drive the two groups of first speed chains 111 to rotate.

[0033] In the present embodiment, the speed chain conveying line is divided into at least two conveying sections, and each conveying section is driven by a driving motor assembly to move the two speed chains. In this way, the speed chain is controlled in sections, each section has a fast response speed, the overall line efficiency is improved, and it is particularly suitable for production lines with long conveying lines.

[0034] In the present embodiment, the first speed chain conveying line 10 is one line, i.e., a single-line conveying line. This conveying line is suitable for relatively simple production lines, and the supporting plate for supporting the product does not need to be recycled. Embodiment Two

[0035] Reference Figure 3 and Figure 4The embodiment two is different from the embodiment one in that a second speed chain conveying line 30 parallel to the first speed chain conveying line 10 is further arranged on the support assembly, and two sets of displacement devices 40 are further arranged on the support assembly. The second speed chain conveying line 30 moves in a second direction, which is parallel and opposite to the first direction. The second speed chain conveying line 30 is mainly used for recycling the supporting plates in the opposite direction, so as to realize the recycling of the supporting plates. The two sets of displacement devices 40 are respectively used for displacing the supporting plates between the first speed chain conveying line 10 and the second speed chain conveying line 30. One set of displacement devices 40 is arranged between the first end of the first speed chain conveying line 10 and the second end of the second speed chain conveying line 30, and is used for displacing the supporting plates on the first speed chain conveying line 10 to the second speed chain conveying line 30. The second speed chain conveying line 30 moves in the second direction in the opposite direction, and moves the supporting plates to the first end of the second speed chain conveying line 10, that is, the end corresponding to the first speed chain conveying line 10. Then, the other set of displacement devices 40 moves the supporting plates at the first end of the second speed chain conveying line 30 to the end of the first speed chain conveying line 10, and the supporting plates carry the products at this position. Then, the first speed chain conveying line 10 moves in the first direction, and drives the supporting plates and the products to move forward, so as to well cooperate with the processing of each station on the production line.

[0036] Similarly, in the embodiment, the second speed chain conveying line 30 also adopts a multi-segment type, and each segment is driven by a driving motor. The segmented control can improve the response speed, and can better match the first speed chain conveying line 10 controlled in a segmented manner, so that the second speed chain conveying line can better cooperate.

[0037] Specifically, the second speed chain conveying line 30 includes at least two second speed conveying segments 31 arranged in sequence at the first end and the second end in the second direction. Each second speed conveying segment 31 includes two sets of second speed chains 311 arranged in parallel, and a second driving motor assembly 50 arranged at the first end and driving the two sets of second speed chains 311.

[0038] Similarly, in the embodiment, the length of the speed chain can be adjusted according to the processing time of each station on the production line or the running speed of the speed chain. In the embodiment, the first speed chain has multiple segments, and the lengths of the segments are not completely same. Of course, the lengths of the second speed chains 311 can be all same or all different.

[0039] In the embodiment, the displacement device 40 comprises a jacking mechanism 41 and three sets of translation tables 42 which are driven by the jacking mechanism 41 to be lifted, and the three sets of translation tables 42 are respectively arranged between the two sets of first speed chains 111, between the two sets of second speed chains 311, and between the first speed chain conveying line 10 and the second speed chain conveying line 30. When the pallet moves along the first speed chain conveying line 10 or the second speed chain conveying line 30, the jacking mechanism moves downward, so that the three sets of translation tables 42 are positioned below the speed chain conveying line and do not hinder the movement of the pallet; when it is necessary to move the pallet between the two speed chain conveying lines, the jacking mechanism 41 drives the three sets of translation tables 42 to move upward, so as to realize the translation of the pallet between the two speed chain conveying lines.

[0040] Specifically, the jacking mechanism 41 comprises a jacking cylinder (not shown in the figure) and a support plate 411 arranged at the top of the jacking cylinder, and the three sets of translation tables 42 are fixed on the support plate 411. In this way, the three sets of translation tables 42 are driven simultaneously by one support plate 411.

[0041] In the embodiment, the translation table 42 comprises a horizontal plate 421 and two sets of belt pulley conveyors 422 arranged on both sides of the horizontal plate 421. The horizontal plate 421 serves as a fixed support, and the two sets of belt pulley conveyors 422 are used to drive the pallet to move. The belt pulley transmission is stable and low in cost.

[0042] Similarly, in the embodiment, the structure of the second driving motor assembly 50 is the same as that of the first driving motor assembly 20, and specifically comprises a second driving motor (not numbered in the figure), a second driving wheel driven by the second driving motor, a second driven wheel connected to the second driving wheel through a belt, and another second driven wheel arranged side by side with the second driven wheel and coaxially connected through a rotating shaft, and two sets of second speed chains are respectively arranged on the two second driven wheels. Of course, the second driving motor assembly can also adopt other structures.

[0043] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which shall be covered within the protection scope of the present application.
