The following uses FIGS. 4 to 9 to explain the operation flow of the conveying device, and in order to clearly expose the sequence of the three conveyed articles 9 and the action relationship between the components, each of the drawings in Figs. 4 to 9 are shown in Figs. A first article 91, a second article 92, and a third article 93 are drawn in the order of conveyance, and the following description is to divide the workbenches 52 into a front workbench 52 relatively adjacent to the front workstation 2 , And a rear workbench 52 relatively adjacent to the rear workstation 3.

When the first article 91 moves to the main conveying module 522 of the front workbench 52 (see FIG. 4), the forward and backward driving module 53 of the front workbench 52 is operated to make the workbench 52 move along the exchange axis X moves to switch to the auxiliary conveying state as shown in FIG. 5, so that the main conveying module 522 and the first article 91 leave the conveying path P. At this time, the main driving module 524 is operated to make the main conveying module 522 stops rotating, so that the first article 91 can stay on the main conveying module 522 for a first operator 81 located on the side of the main conveying module 522 of the workbenches 52 The first article 91 is processed, and the auxiliary driving module 525 of the front workbench 52 is operated to keep the auxiliary conveying module 523 in operation to drive the second article 92 to move along the conveying path P.

Referring to FIG. 6, when the second article 92 arrives at the main conveying module 522 of the rear worktable 52, the third article 93 is also driven to the auxiliary conveying module 523 of the front worktable 52, and waits for the first After the article 91 is processed, the forward and backward drive modules 53 are operated to switch the front workbench 52 to the main conveying state as shown in FIG. 7 and the rear workbench 52 to switch to the auxiliary conveying state.

Operate the auxiliary driving module 525 of the front workbench 52 to stop the auxiliary conveying module 523 from rotating, so that the third article 93 can stay on the auxiliary conveying module 523, so as to provide a vehicle on the workbenches 52 The second operator 82 on one side of the auxiliary conveying modules 523 processes the third article 93. Similarly, operating the main driving module 524 of the rear workbench 52 stops the main conveying module 522 from rotating, so that the second article 92 can stay on the main conveying module 522 for the first operator 81 for processing. In addition, operating the main driving module 524 of the front workbench 52 at the same time can rotate the main conveying module 522, and operating the auxiliary driving module 525 of the rear workbench 52 to rotate the auxiliary conveying module 523, so as to The processed first article 91 is moved to the rear workstation 3 via the main conveying module 522 of the front workbench 52 and the auxiliary conveying module 523 of the rear workbench 52 along the conveying path P (see FIG. 8) Perform subsequent processing operations.

In this way, the third article 93 and the second article 92 can be processed on the front workbench 52 and the rear workbench 52, respectively, and the processed first article 91 can be transported to the rear workstation 3 at the same time. .

After the second article 92 and the third article 93 are processed, the forward and backward drive modules 53 are operated to switch the front workbench 52 to the auxiliary conveying state as shown in FIG. 9 and make the rear work The table 52 is switched to the main conveying state to drive the second article 92 and the third article 93 to return to the conveying path P, and the auxiliary drive module 525 of the front table 52 and the rear The main driving module 524 of the workbench 52 drives the corresponding conveying modules 523 and 522 to rotate, respectively, so that the second article 92 and the third article 93 can be driven to the rear workstation 3 for subsequent processing operations.

In this way, not only can the first operator 81 and the second operator 82 perform processing operations at the same time to increase work efficiency, but also by providing the main conveying modules 522 and the auxiliary conveying modules 523, The workbenches 52 can always maintain the operation of the conveying path P whether in the main conveying state or the auxiliary conveying state. Therefore, when one of the operators 81, 82 finishes the processing operation first, they can also switch one of them first. The worktable 52 transports the processed items 91, 92, 93 to the post workstation 3, and the operators 81, 82 who have completed the processing first can also obtain the next item 91, 92, 93 to be processed for processing, without the need Waiting for another worker 81, 82, so the idle time can be reduced.

It is worth mentioning that in this embodiment, the intermediate workstation 4 includes two such work units 5, and two workers 81, 82 are configured to perform processing on the intermediate workstation 4. However, in other implementation aspects In this case, the intermediate workstation 4 may also include more than three work units 5 and be equipped with more workers 81 and 82 for processing. As long as the operation of the conveying path P can be maintained, the same effect can be achieved.

It should be particularly noted that in this embodiment, the exchange axis X is perpendicular to the conveying path P, however, it is not limited to this, as long as the exchange axis X intersects the conveying path P, and the workbenches 52 are no matter where they are. In the main conveying state or the auxiliary conveying state, the operation of the conveying path P can always be maintained, and the same effect can be achieved.

In addition, in this embodiment, the front conveying module 22, the rear conveying module 32, the main conveying modules 522, and the auxiliary conveying modules 523 all use the form of rollers to drive the article 9 to move. However, in other variations, conveyor belts, conveyor chains, etc., can also be used in other forms.

In summary, by providing the main conveying module 522 and the auxiliary conveying module 523, the workbenches 52 can always maintain the conveying path P regardless of the main conveying state or the auxiliary conveying state. Therefore, at least two operators 81, 82 can perform processing operations at the intermediate workstation 4 at the same time. When one operator 81, 82 completes the processing operation first, it can also switch one of the workbenches 52 to perform processing. The item 9 of the product 9 is transported to the post workstation 3, and the operator 81, 82 who completed the processing operation first can also obtain the next item 9 to be processed for processing without waiting for other operators 81, 82, thus reducing idle time. Therefore, the purpose of the invention can be achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope of the patent of the present invention.
