Example 3

For further facilitating the understanding of the present application, specific examples will be given in this embodiment as follows: FIG. 1 shows a typical process-assembly plant in which SL-1, SL-2, SL-3 are 3 parallel process tools, each having multiple in-process capabilities; JG-1, JG-2 and JG-3 are 3 parallel assembling devices, and each device has the assembling capability of a plurality of products. The rectangular blocks numbered 1-19 in fig. 1 represent 19 sections of roller tables, each section of roller table is provided with an independently controllable power motor and has bidirectional conveying capability, and each section of roller table can simultaneously convey only one product. The production information, the alignment constraint and the sequence constraint related to each product in the assembly process production can be managed. The 2 work orders were constructed as follows:

(WorkID-1，Roller-16，JG-2，Product-1)；

(WorkID-2，Roller-16，JG-2，Product-2)；

taking a work ID-2 of a work order as an example for explanation, a 1 st attribute value work ID-2 represents the work order ID, a 2 nd attribute value represents that work orders required by the work order all need to be conveyed to a Roller-16, a 3 rd attribute value represents that the work order is assembled on a device JG-2, a 4 th attribute value represents that the Product name of the assembled work order is Product-2, and Roller paths sequentially passed by the work order conveying are respectively: 2. and 7, 14, 15 and 16 roller ways. 7 delivery sheets are constructed for the 2 sheets described above:

(SendID-1，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-2，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-3，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-4，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-5，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-6，WIP-1，WorkID-1，Roller-16，SL-2，Roller-15)；

(SendID-7，WIP-2，WorkID-2，Roller-16，SL-2，Roller-14)；

in the following, the second delivery list is taken as an example, the 1 st attribute value SendID-2 is a delivery list ID, the 2 nd attribute value WIP-1 is a product name, the 3 rd attribute value WorkID-1 is a work list number to which the delivery list SendID-2 belongs, the 4 th attribute value Roller-16 is a destination Roller way of the product, the 5 th attribute value SL-2 is a processing device of the product, and the 6 th attribute value Roller-15 is a current 15# Roller way of the product. In fig. 3 and 4, the 7 delivery sheets are represented by ABCDEFG, the delivery sheet SendID-1 corresponds to a, the SendID-7 corresponds to G, and the delivery sheets are placed on the roller table where they are currently located.

When all 6 products of the work ID-1 work order are conveyed to the 14# roller way and the 15# roller way shown in fig. 3, F passes through the RFID sensing equipment, and the products are updated to the 14# roller way. And when F sends a scheduling request, judging whether the next section of 15# pipeline is full, and if the roller way is not full, scheduling the 15# pipeline. When F leaves the current 14# roller way, the detection equipment detects a signal of leaving the roller way, and at the moment, F is cleared from the 14# roller way and updated to the tail of the 15# roller way.

1 product of the work ID-2 work order is conveyed to a 14# roller way, as shown in fig. 4, and G is firstly updated to the 14# roller way after RFID sensing and scheduling request, and then whether the next 15# roller way is full or not is judged. If the product is full at this time, it needs to be determined whether all the delivery orders A, B, C, D, E, F of the 15# roller tables full of the product are valid (according to whether the position of the delivery order is updated to other roller tables or the delivery task is completed), and if all the delivery orders are valid, G needs to continue waiting for the next scheduling.

If A in 6 delivery sheets of the 15# roller way, because the A leaves the 15# roller way, the detection equipment does not detect the leaving signal of A for some reason, the A can be caused to stay on the 15# roller way, when the G request is made, the 15# roller way is false full, the A is removed from the 15# roller way according to the strategy, and then the G is continued to schedule the next section of roller way.

The assembly type workshop roller way scheduling method can not only ensure that products pass through the roller ways orderly, but also solve the problem that a system cannot be scheduled due to the fact that the roller ways are stored fully by mistake caused by faults of other detection equipment such as photoelectricity and the like, and ensure the stable operation of the system to the greatest extent.

The examples of the present invention are merely for describing the preferred embodiments of the present invention, and are not intended to limit the spirit and scope of the present invention, and those skilled in the art should make various changes and modifications to the technical solution of the present invention without departing from the spirit of the present invention.
