Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of production line management systems, and in particular to a glass production line capacity scheduling system. Background Technology
[0002] Automated glass production lines rely on multiple machines working in coordination to complete each stage of glass production. However, in actual production, these machines cannot always maintain a consistent operating state. When a machine malfunctions or a product matching error occurs, forcing the production line to stop for repairs, the capacity and production time of other machines that are still operational are wasted. Furthermore, the downtime and causes of downtime are often difficult to monitor accurately. The time from discovering the downtime to troubleshooting and then to capacity planning is lengthy, preventing production line managers from promptly identifying and efficiently allocating capacity, which severely impacts the production line's efficiency. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a glass production line capacity scheduling system that can monitor the operating status of the production line in a timely manner and automatically allocate capacity to improve the production efficiency of the production line.
[0004] Technical Solution: To achieve the above objectives, this utility model provides a glass production line capacity scheduling system, comprising several production lines arranged in parallel. Each production line includes several pieces of equipment, and adjacent pieces of equipment are connected by a conveying mechanism. A product waiting area is provided in front of each piece of equipment, and a status monitoring module is provided in the product waiting area. A handling mechanism is provided between the conveying mechanisms corresponding to adjacent production lines. The status monitoring module is communicatively connected to the control modules of the handling mechanisms on both sides of it.
[0005] Each of the conveying mechanisms is equipped with a counting module, and the two counting modules at corresponding positions on adjacent production lines are communicatively connected to the control module of the conveying mechanism between them.
[0006] Furthermore, the status monitoring module includes a sensor switch, the sensor switch’s sensor signal output terminal is electrically connected to a timing unit, and the timing unit is communicatively connected to the corresponding control module.
[0007] Furthermore, the status monitoring module also includes an identification module located directly above the product standby area, the induction switch control signal transmission is connected to the identification module, and the identification signal output terminal of the identification module is electrically connected to the feedback signal receiving terminal of the timing unit.
[0008] Furthermore, the counting module includes several sensor groups, which are arranged at equal intervals along the conveying direction of the conveying mechanism. Each sensor group includes a sensing unit fixedly installed on both sides of the conveying mechanism.
[0009] Furthermore, the conveying mechanism includes a base, on which a picking and placing mechanism is provided. The base slides repeatedly along the length of the conveying mechanism. Several positioning sensors are arranged on the slide rail of the base, and the multiple positioning sensors are arranged one-to-one with the multiple sensor groups on both sides.
[0010] Furthermore, the picking and placing mechanism is a robotic arm structure with an adsorption device at its free end.
[0011] Beneficial Effects: This utility model provides a glass production line capacity scheduling system. Based on simultaneous production across multiple production lines, it monitors the operating status and distribution patterns of glass products on each production line using a production line monitoring system. Based on the monitoring results, it controls the handling mechanism 5 to perform handling tasks between adjacent conveying mechanisms 2. This achieves the transfer and scheduling of glass products between equipment at the same location on different production lines, ensuring even product distribution and solving the problems of localized product accumulation caused by the shutdown of individual equipment in the production line system, as well as the wasted capacity of other available equipment on the same production line. This improves the overall production efficiency of the production line system. Attached Figure Description
[0012] Figure 1 This is a partial structural diagram of a glass production line capacity scheduling system according to the present invention;
[0013] Figure 2 This is a schematic diagram of the structural connection of a status monitoring module according to an embodiment of the present invention. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] As attached Figure 1-2The glass production line capacity scheduling system includes several production lines arranged in parallel. Each production line includes several pieces of equipment 1, which are connected to adjacent pieces of equipment 1 via conveying mechanisms 2. Each piece of equipment 1 has a product waiting area 3 in front of it, and a status monitoring module 4 is installed in the product waiting area 3. A handling mechanism 5 is installed between the conveying mechanisms 2 of adjacent production lines. The status monitoring module 4 is communicatively connected to the control modules 6 of the handling mechanisms 5 on both sides. Based on synchronous production across multiple production lines, this system monitors the operating status and distribution patterns of glass products on each production line. Based on the monitoring results, it controls the handling mechanisms 5 to perform handling tasks between adjacent conveying mechanisms 2, thereby achieving the transfer and scheduling of glass products between equipment at the same location on different production lines. This ensures even product distribution and solves the problem of localized product accumulation and wasted capacity of other available equipment on the production line due to the shutdown of individual equipment. By monitoring the operating status of glass products on the production line and providing feedback control for the lateral scheduling and allocation of glass products, it achieves efficient and automatic allocation of available capacity during partial shutdowns, thereby improving the overall production efficiency of the production line system.
[0016] When a piece of equipment stops, it cannot process the glass products output from the preceding equipment, leading to an increase in the number of glass products on its front conveyor mechanism. Once this number accumulates to a certain point, the conveyor mechanism becomes full, and the preceding equipment can no longer output glass products, resulting in a loss of production capacity. To address this, each conveyor mechanism 2 is equipped with a counting module 7. Two counting modules 7 at corresponding positions on adjacent production lines are communicatively connected to the control module 6 of the transport mechanism 5 between them. The counting modules 7 count the glass products on each conveyor mechanism. When the difference in the number of glass products on both sides of the transport mechanism 5 is greater than or equal to two, the transport mechanism is controlled to move glass from the side with the larger number to the side with the smaller number until the numbers on both sides are equal or differ by one. This effectively distributes the pressure on each conveyor mechanism, avoiding impact on the production of available equipment and ensuring efficient use of production capacity.
[0017] The status monitoring module 4 includes a sensor switch 41. The sensor signal output terminal of the sensor switch 41 is electrically connected to a timing unit 42, which is communicatively connected to the corresponding control module 6. The sensor switch 41 is used to sense the presence or absence of glass in the product waiting area 3. The sensor signal output terminal of the sensor switch 41 and the counting feedback signal output terminal of the counting module 7 are electrically connected to the control unit of the conveying mechanism 2. When the sensor switch 41 senses that there is no glass in the product waiting area 3 but there is glass on the conveying mechanism 2, it first controls the conveying mechanism to transport glass products to the product waiting area 3, ensuring timely product supply and improving production efficiency when the equipment is operating normally. When the sensor switch 41 detects the presence of glass products, it starts timing and marks the dwell time. When the dwell time exceeds the limit, it restricts the adjacent conveying mechanisms on both sides to only transport glass products outwards, because the dwell time exceeding the limit may be due to the loss of working capacity of the downstream equipment. Meanwhile, the status monitoring module 4 also keeps track of the idle time when there is no glass in the product standby area 3. When the idle time exceeds the limit, it indicates that the subsequent equipment is working normally and there is no glass product available to be added on the conveyor. At this time, the adjacent handling mechanisms on both sides are controlled to move glass products onto the conveyor until they are evenly distributed.
[0018] The status monitoring module 4 also includes an identification module 43 located directly above the product standby area 3. The control signal transmission of the induction switch 41 is connected to the identification module 43, and the identification signal output terminal of the identification module 43 is electrically connected to the feedback signal receiving terminal of the timing unit 42. To avoid interference from non-glass products causing timing errors and affecting the orderly scheduling, the identification module 43 is set up to identify the sensed object when the induction switch 41 senses it. Preferably, the identification module 43 uses a camera to determine whether the sensed object is the target glass product through image recognition. If it is not the target glass product, the timing is not reset; if it is the target glass product, the timing is reset after it arrives and stops standing by, ensuring the accuracy and reliability of the timing.
[0019] The counting module 7 includes several sensor groups 71, which are arranged at equal intervals along the conveying direction of the conveying mechanism 2. Each sensor group 71 includes a sensing unit fixedly installed on both sides of the conveying mechanism 2. The distance between two adjacent sensor groups is defined as one unit length, and the stroke of the conveying mechanism 2 for each feeding is defined as one unit length. One sensor group on the conveying mechanism corresponds to one product position, and one product position corresponds to one glass product. An empty product position is considered an idle position. The number of glass products is counted by the number of sensor groups that can sense glass products, and the position of the glass products on the conveying mechanism can be determined simultaneously.
[0020] The conveying mechanism 5 includes a base 51, on which a pick-and-place mechanism 52 is mounted. The base 51 slides repeatedly along the length of the conveying mechanism 2. Several positioning sensors are arranged on the slide rails of the base 51, with each positioning sensor corresponding to one of the sensor groups 71 on its sides. During conveying, first, in the unloaded state, the mechanism moves to the position corresponding to the foremost glass on one side, where the pick-and-place mechanism 52 picks up the glass. Then, it moves to the idle product position at the rearmost end of one side to place the glass, completing one conveying operation. The scheduling between multiple production lines is synchronized.
[0021] The pick-and-place mechanism 52 is a robotic arm structure with an adsorption device at its free end. The adsorption device has a negative pressure suction cup structure, which makes the pick-up more stable and safe, without damaging the glass surface. The robotic arm has higher flexibility, and combined with precise movement and alignment, it can effectively ensure the neat arrangement of the glass in each conveying mechanism.
[0022] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
