Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to a control method for a carrier transfer production line. Background Technology

[0002] In the production of clothing, bags, shoes, and other products made from various materials, the necessary materials are automatically transported to the workstations, and the products are automatically output after processing. This process is usually completed on a single assembly line.

[0003] For example, publication number CN217296076U provides a production line for accessories of customized garments. Publication number CN115323651A provides a high-efficiency assembly line for single garment items.

[0004] However, the existing production line operates on a continuous flow basis, requiring production personnel at each workstation to select parts and materials according to orders. This leads to low production efficiency and technical problems such as material mixing errors. Furthermore, inconsistent production efficiency between workstations can cause one step to affect the entire production line, necessitating improvement. Summary of the Invention

[0005] To overcome the problems existing in related technologies, embodiments of the present invention provide a control method for a vehicle transfer production line, which solves the technical problems of mutual restraint between workstations, low production efficiency, and easy mixing of parts during product retrieval.

[0006] According to a first aspect of the present invention, a control method for a vehicle transfer production line is provided, the vehicle transfer production line including a main circulation device, multiple workstations and at least one buffer station: The carrier device moves on the same horizontal plane as the main circulation device and multiple workstations. Each workstation and buffer station is equipped with a power-driven chain mechanism, and the carrier device moves above the chain mechanism. The control method includes: Read the material information contained in the carrier chip on the carrier device; The entry turnout mechanism of the destination workstation on the main circulation device path is opened to guide the vehicle device to enter, and the chain mechanism of the destination workstation drives the vehicle device to move. The blocking device inside the control target workstation blocks the movement path of the vehicle device, and the blocking device pushes the vehicle device to disengage from the chain mechanism; The vehicle device at the very front of the control station is guided into the main circulation device along the exit turnout mechanism; Repeat the above steps until the material on the carrier device has been processed.

[0007] In one embodiment, the foremost vehicle device in the control destination workstation is guided into the main circulation device along the exit turnout mechanism, including: The first blocking mechanism separates the foremost vehicle device from the exit turnout mechanism, and the first blocking mechanism disengages the foremost vehicle device from the chain mechanism.

[0008] In one embodiment, before the departure turnout mechanism is activated, it is determined whether a vehicle device is operating within the collision avoidance range of the main circulation device: When a vehicle device is active within the collision avoidance range, the departure turnout mechanism is delayed in opening.

[0009] In one embodiment, determining whether a vehicle device is operating within the collision avoidance range of the main circulation device further includes: The third blocking mechanism controls the movement of the vehicle within the main circulation device within the collision avoidance range.

[0010] In one embodiment, the blocking device within the control target workstation blocks the movement path of the vehicle device, and the blocking device pushes the vehicle device to disengage from the chain mechanism, further comprising: The fourth blocking mechanism in the control workstation moves, blocking the carrier device to be processed in the processing area, and disengaging the carrier device from the chain mechanism. Within the processing area, the front locking mechanism of the subsequent carrier device slides against the rear locking mechanism of the previous carrier device to disengage the subsequent carrier device from the chain mechanism.

[0011] In one embodiment, the method further includes writing material information to the carrier chip of the carrier device and sending the carrier device into the buffer station; The vehicle devices within the buffer station are controlled to enter the main circulation device in sequence, and the main circulation device is controlled to drive the vehicle devices to move.

[0012] In one embodiment, the method further includes acquiring the material information of the outgoing vehicle device and clearing the original material information of the outgoing vehicle chip.

[0013] In one embodiment, the opening of the entry turnout mechanism of the destination workstation on the main circulation device path to guide the vehicle device into the station includes: Determine the redundancy of the vehicle equipment within the target workstation; When the redundancy is greater than or equal to the preset value, the station turnout mechanism is activated. If the redundancy is less than the preset value, the entry turnout mechanism will not be activated.

[0014] In one embodiment, multiple card readers are provided along the movement path of the main circulation device driving the vehicle device. Before the vehicle device reaches the destination workstation, the card readers identify the vehicle chip.

[0015] In one embodiment, the material information includes the association between the materials carried by the vehicle and the order and processing method; Determine the destination workstation to which the vehicle will arrive.

The carrier device is located above the tracks of the main circulation device and multiple workstations. Each carrier device can carry one or more types of materials. The destination workstation and process are determined according to the contents of the carrier chip, reducing the risk of material mixing and improving production line efficiency.

Detailed Implementation

[0023] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting the present invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] like Figures 1 to 4 As shown, the present invention provides a control method for a vehicle transfer production line, which includes a main circulation device 20, multiple workstations 30, and a buffer station 50. Furthermore, the vehicle transfer production line also includes an output station 40, which is used for inspecting and discharging the processed products.

[0025] The main circulation device 20 has a main track 22 and a main chain located within the main track 22, and multiple workstations 30 are distributed on the outside of the main circulation device 20. Each workstation 30 includes a branch track and a chain mechanism 33 located within the branch track. The branch track and the main track 22 are on the same horizontal plane. The carrier device 10 moves between the branch track and the main track 22, and the pallet 11 is located above the horizontal plane.

[0026] The carrier device 10 is equipped with two or more layers of pallets 11, each layer of pallets 11 carrying at least one type of material, and each carrier device 10 carries materials for processing at least one type of product. The pallets 11 are designed with a multi-layer structure, which can classify and place materials; furthermore, the pallets 11 can be divided into multiple areas, that is, multiple types of materials can be placed on the same layer of pallets 11, so as to meet the material requirements of the carrier device 10 for loading the current product at one time, improve the selection efficiency of material distribution, and avoid material mixing.

[0027] A switch mechanism is provided at the connection between the workstation 30 and the main circulation device 20, a switch mechanism is provided at the connection between the buffer station 50 and the main circulation device 20, and a switch mechanism is provided at the connection between the discharge station 40 and the main circulation device 20.

[0028] The carrier device 10 is used to carry materials. The carrier device 10 can move between the main circulation device 20, multiple workstations 30, buffer station 50, and discharge station 40. The main circulation device 20, multiple workstations 30, and buffer station 50 can provide production, circulation, and scheduling. The carrier device 10 includes a carrier body 12 and a rear locking hook mechanism 14 and a front locking hook mechanism 13 movably disposed at both ends of the carrier body 12.

[0029] The main circulation device 20, the workstation 30, and the exit turnout mechanism 32 work together to guide the carrier device 10 to move directionally to the workstation 30. The main chain is equipped with protrusions, which, as the main chain moves, cooperate to move the front locking hook mechanism 13.

[0030] Each workstation 30 is equipped with a power-driven chain mechanism 33, which rotates within the workstation 30 to form a circular motion area. The chain mechanism 33 can guide the carrier device 10 to move unidirectionally along the support track, thereby enabling the carrier device 10 to move in a specific direction.

[0031] The control method for this vehicle transfer production line includes the following steps: S101, read the material information contained in the carrier chip on the carrier device 10; the buffer station 50 can accommodate multiple carrier devices 10, and the multiple carrier devices 10 enter the main circulation device 20 one by one in sequence. A card reader is set on the main circulation device 20 or the buffer station 50, which can obtain the material information of the current carrier device 10 passing through the card reader. The carrier chip of the carrier device 10 is written with the information of the current material, including but not limited to: the association between the material carried by the carrier device 10 and the order and processing method; and determining the destination workstation 30 to which the carrier device 10 arrives. Among them, the processing method contained in the material information is related to the processing technology of the corresponding product. Preferably, a display screen is set on the workstation 30, which can display the process flow corresponding to the material information.

[0032] The material information includes processing methods with relevant information about the destination workstation 30. When the main circulation device 20 drives the carrier device 10 to approach the destination workstation 30, the card reader reads the material information and controls the entry turnout mechanism 31 of the corresponding destination workstation 30 to open.

[0033] S102, the entry turnout mechanism 31 of the main circulation device 20 on the path of the destination workstation 30 is opened to guide the vehicle device 10 to enter, and the chain mechanism 33 of the destination workstation 30 drives the vehicle device 10 to move.

[0034] The target workstation 30 has personnel who produce the materials carried by the vehicle device 10. The entry turnout mechanism 31 of the workstation 30 is opened under the control of the control signal and enters the main circulation device 20, thereby guiding the corresponding vehicle device 10 into the station.

[0035] The front locking hook mechanism 13 of the vehicle device 10 is hooked to the chain mechanism 33 of the destination workstation 30. Accordingly, the vehicle device 10 moves horizontally at the destination workstation 30 under the drive of the chain mechanism 33. The front locking hook mechanism 13 is hooked to the chain mechanism 33 of the workstation 30 for active drive, and the main circulation device 20 no longer outputs power to the vehicle device 10.

[0036] S103, the blocking device within the target workstation 30 blocks the movement path of the carrier device 10, and the blocking device pushes the carrier device 10 to disengage from the chain mechanism 33. The blocking device blocks the carrier device 10 in sections within the target workstation 30, which can form different areas within the workstation 30, such as a processing area, a waiting-to-leave area, a waiting-to-process area, etc. When blocking, the blocking device pushes the front locking hook mechanism 13, causing the front locking hook mechanism 13 to disengage from the chain mechanism 33. Accordingly, the carrier device 10 loses the driving force of the chain mechanism 33 and stops on the support rail, where it can be used for production or temporary storage.

[0037] The device can be equipped with one or more barriers to achieve different control methods. For example, multiple barriers can be configured to achieve segmented control, with individual vehicle devices spaced 10 intervals, etc.

[0038] S104, the foremost carrier device 10 in the destination workstation 30 is guided into the main circulation device 20 along the exit switch mechanism 32. In the destination workstation 30, the foremost carrier device 10 is in a state where material processing is complete and it is ready to enter the exit area. The exit switch mechanism 32 is opened, the blocking device releases its obstruction of the carrier device 10, the front locking hook mechanism 13 swings downward and connects to the chain mechanism 33, and the carrier device 10, driven by the chain mechanism 33, exits the current workstation 30.

[0039] Repeat steps S101-S104 until the material on the carrier device 10 is processed.

[0040] The materials carried by the carrier device 10 can be processed jointly through multiple workstations 30. After the process in each workstation 30 is completed, the materials enter the main circulation device 20. After the card reader on the main circulation device 20 identifies the materials, it controls the opening of the entry turnout mechanism 31 of the next destination workstation 30 to perform the corresponding production process.

[0041] After the carrier device 10 passes through all the workstations 30 where the material information is input, the material processing is completed. The carrier device 10 can carry the sorted materials and transport them to each independent workstation 30 through the main circulation device 20. The workstations 30 cooperate with each other, and each workstation 30 completes the corresponding production process of the product, which greatly improves the overall production efficiency and the rationality of material allocation.

[0042] Multiple card readers are installed along the movement path of the main circulation device 20 driving the carrier device 10. Before the carrier device 10 reaches the destination workstation 30, the card readers identify the carrier chip. The card readers read the material information of the carrier devices 10 they pass through, thereby driving the current carrier device 10 to the destination workstation 30 it needs to enter. The card readers are located in the area before the workstation 30. Before the carrier device 10 enters the destination workstation 30, it needs to determine whether the destination workstation 30 allows entry.

[0043] In step S102 above, controlling the entry turnout mechanism 31 of the main circulation device 20 to open and guide the vehicle device 10 to enter the destination workstation 30 includes the following control steps: The redundancy of the vehicle devices 10 within the destination workstation 30 is determined. This redundancy is the number of vehicle devices 10 that can still be accommodated within the workstation 30. The maximum capacity of vehicle devices 10 within the destination workstation 30 is a preset value. Sensors or sensing elements are installed in the corresponding areas of the workstation 30 to control the quantity in the current area. Alternatively, the number of vehicle devices 10 within the destination workstation 30 can be determined by the number of times the entry turnout mechanism 31 and the exit turnout mechanism 32 are opened. Alternatively, redundancy can be calculated using other methods.

[0044] When the redundancy is greater than or equal to the preset value, the entry turnout mechanism 31 is opened. The destination workstation 30 has redundancy, and the controller controls the entry turnout mechanism 31 to open, guiding the carrier device 10 into the destination workstation 30 for corresponding processing.

[0045] When the redundancy is less than a preset value, the entry turnout mechanism 31 will not open. The controller controls the entry turnout mechanism 31 to remain closed, and controls the carrier device 10 to circulate along the main circulation device 20, waiting for the next opportunity to enter the destination workstation 30. Alternatively, the controller controls the carrier device 10 to circulate along the main circulation device 20 to enter another workstation 30 with redundancy, perform other non-conflicting processing operations first, and then circulate along the main circulation device 20 to enter the destination workstation 30 to perform the corresponding processing operations.

[0046] In step S104 above, the foremost carrier device 10 outputs a single unit after completing the process of the current workstation 30, so as to proceed to the next process. The output of the foremost carrier device 10 further includes the following steps: S201, the first blocking mechanism 34 separates the foremost vehicle device 10 from the exit switch mechanism 32, and disengages the foremost vehicle device 10 from the chain mechanism 33. The first blocking mechanism 34 is rotatably connected to the support rail of the workstation 30. The blocking plate of the first blocking mechanism 34 blocks the foremost vehicle device 10 to prevent it from impacting the exit switch mechanism 32, thus achieving controllable exit timing. Preferably, the blocking plate of the first blocking mechanism 34 pushes the front locking hook mechanism 13 to rotate, thereby disconnecting the power between the front locking hook mechanism 13 and the chain mechanism 33, and the vehicle device 10 is in a stopped state.

[0047] S202, the second blocking mechanism 35 separates the foremost carrier device 10 from the rear carrier device 10, and disengages the rear carrier device 10 from the chain mechanism 33. The foremost carrier device 10 is located between the first blocking mechanism 34 and the second blocking mechanism 35, forming an independent unit waiting to leave the station, while the rear carrier devices 10 can continue production. The blocking sequence of the first blocking mechanism 34 and the second blocking mechanism 35 is adjustable to match the production rhythm, ensuring orderly exit. The first blocking mechanism 34 and the second blocking mechanism 35 have the same structure, using a cylinder to drive the blocking plate to rotate and block. The first blocking mechanism 34 and the second blocking mechanism 35 constitute the blocking device.

[0048] S203, the control switch mechanism 32 opens, the first blocking mechanism 34 resets, and the chain mechanism 33 drives the foremost vehicle device 10 to leave the station. After the second blocking mechanism 35 completes its blocking, the foremost vehicle device 10, having completed individual blocking, enters the waiting-to-leave state. The first blocking mechanism 34 resets and moves to the side of the branch track, then the front locking hook mechanism 13 rotates and connects to the chain mechanism 33, and the chain mechanism 33 drives the vehicle device 10 to leave the station and enter the main circulation device 20.

[0049] Before the vehicle device 10 enters the waiting area and the exit turnout mechanism 32 is activated, it is necessary to further determine whether the vehicle device 10 is operating within the collision avoidance range of the main circulation device 20.

[0050] When the collision avoidance range has the vehicle device 10 in motion, the exit turnout mechanism 32 is delayed in opening.

[0051] When no vehicle device 10 is active within the collision avoidance range, the exit turnout mechanism 32 is activated.

[0052] The main circulation device 20 is equipped with a detection mechanism that can detect the movement status of the vehicle device 10 of the main circulation device 20, thereby preventing collisions. The detection mechanism can be configured as a sensor for detection.

[0053] The exit turnout mechanism 32 rotates toward the track of the main circulation device 20, and the main chain in the main track 22 rotates in a cycle, thereby driving the exit vehicle device 10 to move.

[0054] Furthermore, when there are a large number of carrier devices 10 in the main circulation device 20, such as when the carrier devices 10 loaded with unprocessed materials and the carrier devices 10 loaded with finished products are crowded in the main circulation device 20, the third blocking mechanism 21 is controlled to block the carrier devices 10 in the main circulation device 20.

[0055] In particular, controlling the third blocking mechanism 21 to block the vehicle device 10 in the main circulation device 20 from moving within the collision avoidance range can both provide temporary control of the vehicle device 10 and prevent the vehicle device 10 from colliding.

[0056] like Figures 1 to 4 As shown, step S103 above further includes the following control steps: In step S1031, the fourth blocking mechanism within the workstation 30 is controlled to move. The fourth blocking mechanism blocks the carrier device 10 to be processed within the processing area and disengages the carrier device 10 from the chain mechanism 33. The workstation 30 uses multiple blocking devices for separation, with the second blocking mechanism 35 located between the fourth blocking mechanism and the first blocking mechanism 34. The carrier device 10 awaiting departure is accommodated between the first blocking mechanism 34 and the second blocking mechanism 35; the carrier device 10 undergoing processing is accommodated between the second blocking mechanism 35 and the fourth blocking mechanism; and multiple carrier devices 10 awaiting processing are accommodated between the fourth blocking mechanism and the entry turnout mechanism 31.

[0057] In the processing area, the front locking hook mechanism 13 of the next carrier device 10 slides against the rear locking hook mechanism 14 of the previous carrier device 10 to disengage the next carrier device 10 from the chain mechanism 33.

[0058] The processing area can accommodate multiple carrier devices 10. The front locking hook mechanism 13 of the last carrier device 10 slides against the rear locking hook mechanism 14 of the previous carrier device 10 to disengage the last carrier device 10 from the chain mechanism 33. All carrier devices 10 are disengaged from the chain mechanism 33 and are in a stopped state with power disconnected.

[0059] It is worth mentioning that the chain mechanism 33 inside the workstation 30 can move continuously, and the power to the carrier device 10 in the processing area is disconnected, which does not affect the power transmission of the carrier device 10 in the waiting area and the processing area.

[0060] Before the carrier device 10 enters the flow area of ​​the main circulation device 20, it is necessary to associate material information with the materials.

[0061] The control method for the carrier transfer production line also includes writing material information into the carrier chip of the carrier device 10 and sending the carrier device 10 into the buffer station 50. The carrier chip associates the material information with the carrier device 10. The material information includes related information such as processing technology, material specifications, type, and corresponding workstation 30, and may even include other production management information such as allocation method and work price.

[0062] The buffer station 50 serves as a temporary storage area after the loading of the carrier device 10 is completed; and the buffer station 50 serves as a transfer area for the carrier device 10 during processing.

[0063] The vehicle devices 10 in the control buffer station 50 sequentially enter the main circulation device 20, and the main circulation device 20 drives the vehicle devices 10 to move.

[0064] The buffer station 50 can buffer and accommodate a corresponding number of carrier devices 10, wherein each type of material is placed in a corresponding tray 11, and each tray 11 carries at least one type of material; the tray 11 is located in the space above the track in the carrier flow production line, which can facilitate picking up and placing and loading materials. Preferably, the material loading process can be automatic loading or manual loading.

[0065] After the materials are delivered, the corresponding information is entered into the carrier chip. The carrier chip is located on one side of the carrier device 10, and the card reader can read the corresponding information during the movement of the carrier device 10.

[0066] The carrier device 10 is moved to the buffer station 50. During manual loading, the carrier device 10 can be placed entirely on the track of the buffer station 50 after external loading. During automatic loading, the carrier device 10 remains on the track of the buffer station 50, and the loading mechanism can load materials onto the carrier device 10.

[0067] The fifth blocking mechanism controls the carrier device 10 conveyed by the buffer station 50, thus controlling the carrier device 10 entering the main circulation device 20 as one unit. The fifth blocking mechanism is a telescopic mechanism that can block the carrier device 10 before it enters the main circulation device 20, and the buffer station 50 constitutes a buffer area.

[0068] After the carrier device 10 completes all the processing steps, it needs to be output from the main circulation device 20.

[0069] The control method further includes acquiring the material information of the outgoing carrier device 10 and clearing the original material information from the outgoing carrier chip. The discharge station 40 or the main circulation device 20 is equipped with a card reader. After the carrier device 10 enters the range of the card reader corresponding to the discharge station 40, the card reader outputs a corresponding signal, and the entry switch mechanism 31 of the discharge station 40 opens, allowing the main circulation device 20 to transport the carrier device 10 to the discharge station 40.

[0070] The unloading station 40 inspects the product based on the material information. When the product is qualified, the product carried by the carrier device 10 is taken out, the material information of the carrier device 10 is cleared, and the carrier device 10 is used as an empty carrier for the next cycle.

[0071] When the product fails inspection, the exit switch device of the discharge station 40 is opened, the carrier device 10 is sent into the main circulation device 20, and then the carrier device 10 is sent to the corresponding workstation 30 for rework through the main circulation device 20.

[0072] The discharge station 40 is located on one side of the main circulation device 20 and adjacent to the buffer station 50. After the discharge workbench removes qualified products, an empty carrier device 10 is formed. Furthermore, the carrier chip in the carrier device 10 is cleared, resulting in blank information. The carrier device 10 can then be reloaded with materials to improve turnover efficiency. The carrier chip allows for convenient writing and clearing of material information, improving online traceability capabilities.

[0073] When a product fails inspection, the information from the carrier chip can be used to identify the workstation 30 that produced the product, and the product can be sent back to the original workstation 30 via the main circulation device 20; or, the product can be sent to the rework workstation 30 via the main circulation device 20.

[0074] It should be understood that this application is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of this application and include common knowledge or customary techniques in the art that are not disclosed in this invention.
