Description

TECHNICAL FIELD

[0001] The utility model relates to workpiece conveying technical field, specifically is a kind of conveying chain based on positive conveying of climbing chain section. BACKGROUND

[0002] At present, for the conveying of workpiece, such as in the field of spraying technology, the workpiece whose surface has been uniformly sprayed, when it is carried out next process, i.e. solidification, needs to be sent into solidification furnace by conveying mechanism to realize solidification operation.

[0003] Specifically, such as Figure 1 The conveying mechanism of this type of solidification furnace is a conveying belt 200 installed in the furnace body 100 along the length direction of the furnace body 100, and the two ends of the conveying belt 200 respectively extend out of the furnace body 100. When operating, the worker places the workpiece to be solidified, such as the vacuum cup 300, in the positive direction (the cup body bottom is below, and the top is above) on the belt body 201 at the upper position of the conveying belt 200, and then the conveying belt 200 drives the vacuum cup 300 to pass through the furnace body 100 in the positive direction (the cup body bottom is below, and the top is above) on the belt body 201 at the upper position, completes solidification, and performs next piece on the belt body 201 at the same upper position at the other end of the conveying belt 200.

[0004] It can be seen that the conveying mechanism adopts the conveying belt 200, considering that the vacuum cup 300 needs to be placed in the positive direction during the process of this process, so only the belt body 201 at the upper position of the conveying belt 200 can be used to realize the positive placement of the workpiece. If the vacuum cup 300 is placed on the belt body 202 at the lower position, when the vacuum cup 300 runs to the end 203 of the conveying belt 200, the vacuum cup 300 cannot be placed in the positive direction, and will be tilted, even if there is a positioning structure to fix the vacuum cup 300 to prevent it from tilting, but the vacuum cup 300 cannot be transported in the positive direction in the state of positive placement at the end 203.

[0005] Based on this, the inventors of the present application have developed a conveying chain set to enable the conveying chain set to realize forward conveying of workpieces at the end. Specifically, the basic idea is as follows: the conveying chain set is provided with two symmetrical conveying chains, a plurality of trays are mounted between the chains of the two conveying chains, so that the trays are formed with one end connected to the chain and the other end in a free state, and a guide wheel is arranged at the other end in the free state on the tray, and a guide gear with the same size and structure is arranged at the end sprocket of the conveying chain set. In this way, when the tray runs to the end section of the conveying chain set, the guide wheel gradually enters the tooth groove of the guide gear, and the guide gear supports the guide wheel through the tooth groove to form lifting and driving of the other end in the free state on the tray, so that the tray can still maintain the state of forward installation and connection when the chain runs around the end sprocket. At this time, the tray still in the state of forward installation and connection can realize forward placement of the workpiece at the end section, and finally realize forward conveying of the workpiece at the end section. It should be noted that the forward installation and connection can be understood as the installation and connection state of the workpiece in the forward placement.

[0006] It can be seen that through the above-mentioned conveying chain set, the problem of forward conveying of workpieces at the end section of the conveying chain set is solved, but for the multi-layer winding conveying chain set, in addition to the end section, a climbing chain section is also formed on the circumference of the conveying chain set. How to design the structure to enable the workpiece at the climbing chain section to be forward conveyed needs to be conceived and designed by the inventors of the present application.

The two sides of the tray 3 are respectively provided with mounting shafts 4, the chain (not marked) of the first conveying chain 1 is connected with the mounting shaft 4 on one side of the tray 3, the chain (not marked) of the second conveying chain 2 is connected with the mounting shaft 4 on the other side of the tray 3, the first conveying chain 1 and the second conveying chain 2 are both provided with a climbing chain section 5 and a climbing sprocket 6 arranged on the upper and lower sides of the climbing chain section 5, and the tray 3 is further provided with a guide wheel assembly, the climbing chain section 4 is provided with a climbing guide rail piece, and the tray 3 is positively mounted and connected by the support and guiding action of the climbing guide rail piece on the guide wheel assembly when running to the climbing chain section 5, so that the positive conveying of the workpiece 7 on the climbing section is realized. It should be noted that in the embodiment, the mounting connection of the mounting shaft 4 and the chain can be that the mounting shaft 4 is inserted and connected into the center hole (not shown) of the roller 14 of the chain.

[0027] In the embodiment, the mounting shaft 4 is located on the two sides of one end of the tray 3, and the guide wheel assembly comprises first guide wheels 8 located on the two sides of the other end of the tray 3. In this way, one end of the tray 3 is mounted and connected to the corresponding chain through the mounting shafts 4 on the two sides, and the other end of the tray 3 is in a free state and is provided with the first guide wheels 8.

[0028] For the climbing guide rail piece, in the embodiment, the climbing guide rail piece comprises a first climbing guide rail piece 9, and the first guide wheels 8 run along the first climbing guide rail piece 9. In this way, the first climbing guide rail piece 9 provides support for the first guide wheels 8 and can guide the first guide wheels 8 to run along it, so that when the tray 3 runs on the climbing chain section 5, the other end in a free state is supported and guided to run on the end, so that the tray 3 can also form a positive mounting connection at the climbing chain section 5, so as to realize the positive conveying of the workpiece 7.
