Description

Technical Field

[0001] The present invention relates to the technical field of workshop planning, and in particular to a glass production workshop planning method and system based on RGV trolley load. Background Art

[0002] In the production process of digital manufacturing workshops, material distribution is a very important link. With the personalized development of market demand, the production model of enterprises has changed from single-variety mass production to multi-variety small-batch production. In particular, as the concept of just-in-time production has been gradually adopted and promoted by manufacturing companies, the "near-zero inventory production" and "just-in-time delivery" material distribution model has become one of the key means for manufacturing companies to reduce inventory costs and improve production efficiency. This makes the material distribution of digital manufacturing workshops increasingly arduous and complex. How to ensure that the various material resources required for workshop production are delivered to the correct processing location at the right time and in the right quantity has become a bottleneck problem that needs to be solved in the material distribution of digital manufacturing workshops. For example, a Chinese invention patent discloses an RGV scheduling method based on a serial scheduling algorithm, including an RGV scheduling system and a serial scheduling algorithm. The RGV scheduling system includes an RGV scheduling interface, which is characterized in that: the serial scheduling algorithm is placed in the RGV scheduling interface, and the serial scheduling algorithm first pre-creates a configuration file about the line layout, RGV track, and scheduling task priority level; then after obtaining the pre-configured configuration file, the optimal path and the RGV scheduling task allocation operation are performed, and the corresponding control instructions are generated. Finally, the instructions are sent to the RGV for execution through the RGV interface provided by the equipment manufacturer, thereby realizing the panel handling efficiency when controlling multiple RGVs corresponding to multiple automated production lines, thereby improving the utilization rate of the RGV and the flow speed of the panels between each process.

[0003] In the glass production workshop, after the materials are fed and cleaned, the RGV trolley transports the cassette (CST) storing the glass to the OHS, and then to the stocker (STK) where the next process equipment (EQ) is located. This cycle continues until the production of a single piece of glass is completed. After the production of a single piece of glass is completed, the RGV trolley transports the CST from the STK to the corridor and sends it to the bonding workshop for bonding.

[0004] Generally, a single complete transport of the RGV trolley requires two transports. The first transport is from the RGV trolley to the EQP, and the second transport is from the RGV trolley to the OUT port. Since the RGV trolley cycle is faster than the EQP cycle, the CST can only be placed in the storage position before being sent to the EQP. Since the RGV trolley is not at the required CST transport position when receiving the command, a period of empty running will be generated. The equipment manufacturer provides this value as 2 / 3 of the STK length.

[0005] During the production process, due to the lack of management of glass distribution in the workshop, congestion often occurs between RGV carts, which not only hinders the improvement of production capacity, but also increases production costs. Summary of the invention

[0006] During the distribution process in the glass production workshop, the operation of the RGV cart will produce a part of empty running. On the other hand, due to poor workshop planning, congestion often occurs when the production capacity is increased, which reduces production efficiency and increases production costs.

[0007] In view of the above problems, a planning method and system for a glass production workshop based on the RGV trolley load are proposed. The RGV trolley is detected to obtain the handling parameters, and the handling parameters are used to calculate the handling load of the RGV trolley per unit time. The glass production workshop is secondary planned according to the handling load and the planning image is output. The congestion of the storage device caused by the increase in production capacity is adjusted accordingly, and the layout in the workshop is optimized, and the smoothness of STK transportation is improved to achieve more efficient and energy-saving production, increase production capacity, and reduce costs; avoid congestion of the storage device STK due to increased production capacity, which will affect the production of equipment and reduce abnormal time.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0071] During the distribution process in the glass production workshop, the operation of the RGV cart will produce a part of empty running. On the other hand, due to poor workshop planning, congestion often occurs when the production capacity is increased, which reduces production efficiency and increases production costs.

[0072] Aiming at the above problems, a glass production workshop planning method and system based on RGV trolley load is proposed.

[0073] First, as Figure 1 , Figure 1It is a schematic diagram of the first embodiment of the glass production workshop planning method based on the RGV trolley load in the present invention. A glass production workshop planning method based on the RGV trolley load includes: step 100, using the handling parameters to calculate the RGV trolley's handling load per unit time; step 200, secondary planning of the glass production workshop according to the handling load and output of the planning image; wherein the handling parameters include the layout of the handling nodes and the time to complete a single handling task. By detecting the RGV trolley, the handling parameters are obtained, and the handling parameters are used to calculate the RGV trolley's handling load per unit time, and the glass production workshop is secondary planned according to the handling load and the planning image is output; accordingly, the congestion of the storage device caused by the increase in production capacity is adjusted, and then the layout in the workshop is optimized, and the smoothness of STK handling is improved, so as to achieve more efficient and energy-saving production, increase production capacity, and reduce costs; avoid congestion of the storage device STK due to the increase in production capacity, thereby affecting the production of equipment and reducing abnormal time.

[0074] Preferably, if Figure 2 , Figure 2 It is a schematic diagram of the second embodiment of the glass production workshop planning method based on the RGV trolley load in the present invention, and step 100 includes: step 110, obtaining the node distribution of all production nodes that complete a single handling task; step 120, using the node distribution to obtain the glass material process route of all production nodes in series.

[0075] like Figure 7 and 8 , Figure 7 This is a schematic diagram of the internal handling of the storage container STK in the present invention. Figure 8 It is a distribution diagram of the glass production workshop in the present invention. The glass production workshop includes nodes such as entrance, storage, production equipment, material storage, and exit. Often, to complete a production process, all nodes need to be connected in series, that is, the RGV car needs to traverse all nodes in a single task.

[0076] Preferably, if Figure 3 , Figure 3 It is a schematic diagram of the third embodiment of the glass production workshop planning method based on the RGV trolley load in the present invention. Step 100 also includes: Step 130, decomposing the glass material process route to obtain all the walking routes of the RGV trolley to complete the handling task; Step 140, according to the walking route, obtaining the operating action category of the RGV trolley to complete all the walking routes; wherein the operating action categories include: loading and unloading, acceleration and deceleration, maximum speed, and empty running.

[0077] In the glass production workshop, after the material is fed and cleaned, the RGV cart will transport the cassette storing the glass (hereinafter referred to as CST) to the transfer station (hereinafter referred to as OHS), and then transfer it to the storage device (hereinafter referred to as STK) where the next process equipment (hereinafter referred to as EQ) is located. This cycle continues until the production of a single piece of glass is completed. After the production of a single piece of glass is completed, the RGV cart will transport the CST from the STK to the corridor and send it to the bonding workshop for bonding.

[0078] Generally, a single complete transport of the RGV trolley requires two transports. The first transport is from the RGV trolley to the EQP, and the second transport is from the RGV trolley to the OUT port. Since the RGV trolley cycle is faster than the equipment EQP cycle, the CST can only be placed in the storage position before being sent to the EQP. Since the RGV trolley is not at the required CST transport position when receiving the command, a period of empty running will be generated, which is 2 / 3 of the STK length.

[0080] Therefore, the RGV trolley actually needs four moves to complete a complete transport. The first is to run idly for 2 / 3S after receiving the command to pick up the CST from the IN port and put it in the storage position; the second is to run idly for 2 / 3S after receiving the command to move the CST from the storage position to the EQP; the third is to run idly for 2 / 3S after receiving the command to move the CST that has finished the goods on the EQP to the storage position; the fourth is to run idly for 2 / 3S after receiving the command to move the CST in the storage position to the OUT port.

[0081] Each of the four transfers includes four acceleration and deceleration times and one loading and unloading time. By detecting the speed of the RGV trolley, the T required to reach Vmax and the movement S within this T are calculated.

[0082] Single task time = T1*8+16*T2+T3*4+T4 (T1 = loading and unloading time; T2 = acceleration and deceleration time; T3 = 2 / 3 of the idle running time; T4 = the time of transporting at the maximum speed.)

[0083] Preferably, if Figure 5 , Figure 5 It is a schematic diagram of the fifth embodiment of the glass production workshop planning method based on the RGV trolley load in the present invention, and step 160 includes: step 161, respectively calculating the time required to complete any operating action category; step 162, summing the time required to complete all operating action categories of a single production task to obtain the single task running time.
