Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a material turnover system suitable for mixed-line machining. Background Technology

[0002] Mixed-line processing is a flexible production organization model in manufacturing. It involves simultaneously or alternately producing multiple types and specifications of products on the same production line or within the same production area. This breaks the limitations of traditional single-product dedicated line production and enables the sharing and dynamic allocation of production resources. Mixed-line processing can accommodate two or more products with different processes, raw materials, or specifications but overlapping core processes, effectively improving equipment utilization and ensuring efficient equipment operation.

[0003] Mixed-line machining essentially combines multiple process equipment and centrally schedules them. For any single process, there is no difference from traditional processes. For example, the milling process used in mixed-line machining is not fundamentally different from the machining process of a single milling machine. Therefore, mixed-line machining mostly utilizes traditional processing equipment in combination and layout.

[0004] However, traditional processing equipment serves a single step, typically featuring its own bed and table, which are fixed in place. Even with equipment that allows for interchangeable tables, only two tables correspond to a specific bed, merely improving loading and unloading efficiency. Therefore, when traditional processing equipment is used directly in mixed-line processing, its interactivity in material transfer is poor. Summary of the Invention

[0005] This invention addresses the problem that traditional processing equipment is poorly suited for mixed-line processing by providing a material turnover system suitable for mixed-line processing.

[0006] To address the aforementioned problems, this utility model adopts a material turnover system suitable for mixed-line processing, comprising a processing bed, a non-processing bed, and a material tray. Both the processing bed and the non-processing bed are equipped with a push-pull mechanism and a first guide rail. The material tray is equipped with a traction component that cooperates with the push-pull mechanism and a groove that cooperates with the first guide rail. Both the processing bed and the non-processing bed are also equipped with a positioning mechanism for positioning the material tray. The system also includes a material trolley with a second guide rail that cooperates with the groove. This system is suitable for mixed-line processing, allowing each processing machine to be equipped with a processing bed, while the non-processing bed is used for material tray turnover. The material trolley facilitates the transfer of the material tray between the processing bed and the non-processing bed. The material tray is no longer limited to a single machine, achieving universality for the bed and tray of each processing machine, better adapting to the material turnover needs of mixed-line processing, and improving material turnover efficiency.

[0007] As a preferred implementation of a material handling system suitable for mixed-line processing, the push-pull mechanism includes a drive gear connected to a drive motor. The drive gear is mounted on the upper surface edge of both the processing bed and the non-processing bed. The traction element is a rack, with at least one end of the rack protruding from the side edge of the material tray and capable of meshing with the drive gear. Through the meshing of the drive gear and the rack, stable push-pull transmission of the material tray between the bed and the material trolley can be achieved, improving the automation and accuracy of material handling and further adapting to the high-efficiency turnover requirements of multiple devices and multiple trays in mixed-line processing.

[0008] As a preferred implementation of a material handling system suitable for mixed-line processing, the push-pull mechanism further includes a sliding plate, which is slidably mounted on the processing bed and the non-processing bed. A telescopic assembly is provided between the sliding plate and the corresponding processing bed and non-processing bed. The telescopic direction of the telescopic assembly is the same as the extension direction of the first guide rail. The drive gear and the drive motor are both mounted on the sliding plate. By moving the sliding plate, drive gear, and drive motor as a whole through the telescopic assembly, the range of action of the push-pull mechanism can be flexibly adjusted to adapt to the pushing and pulling needs of material pallets of different specifications. Simultaneously, when not performing push-pull operations, it retracts to the edge of the bed to avoid interference with material carts or other equipment, enhancing the system's compatibility and space utilization in mixed-line processing scenarios.

[0009] As a preferred implementation of a material handling system suitable for mixed-line processing, the drive motor is mounted on the bottom surface of the slide plate, and the output shaft of the drive motor passes through the bottom surface of the slide plate and is equipped with the drive gear. Concealing the drive motor on the bottom surface of the slide plate reduces the space occupied by the equipment on the machine bed surface, reduces the impact of debris and oil on the motor in the processing environment, and extends the service life of the equipment.

[0010] As a preferred implementation of a material handling system suitable for mixed-line processing, one set of push-pull mechanisms is provided on the processing bed; two sets of push-pull mechanisms are provided on the non-processing bed, with each set located on an opposite side of the non-processing bed, and the extension directions of the telescopic components of the two sets of push-pull mechanisms are opposite. The two sets of opposing push-pull mechanisms on the non-processing bed enable bidirectional transfer of material pallets between different material carriages or different beds, reducing turnaround waiting time at the non-processing position and improving the flexibility and efficiency of material scheduling in mixed-line processing.

[0011] As a preferred implementation of a material handling system suitable for mixed-line processing, the bottom of the chute is equipped with multiple rollers arranged along the length of the chute. These rollers are capable of rolling contact with the top surfaces of the first and second guide rails. This rolling contact between the rollers and the guide rails significantly reduces the frictional resistance of the material pallet during transport, reduces the power consumption of the push-pull mechanism, avoids hard wear between the chute and the guide rails, extends the equipment's service life, and ensures stability in high-frequency transport scenarios during mixed-line processing.

[0012] As a preferred implementation of a material handling system suitable for mixed-line processing, the positioning mechanism includes a hydraulic cylinder, which is vertically installed in the corresponding machining position bed or the non-machining position bed. The telescopic rod end of the hydraulic cylinder is provided with a cylindrical pin, and the bottom of the material tray has a pin hole into which the cylindrical pin can be inserted. Through the precise engagement of the cylindrical pin driven by the hydraulic cylinder with the pin hole, the material tray can be quickly positioned and fixed on the bed, avoiding accuracy deviations caused by tray wobbling during processing or transfer. This is particularly suitable for the stringent requirements of different products in mixed-line processing for machining positioning accuracy, improving the stability of processing quality.

[0013] As a preferred implementation of a material handling system suitable for mixed-line processing, the positioning mechanism further includes a connecting sleeve, which is fixedly connected to the corresponding machining bed or non-machining bed. The cylinder body of the hydraulic cylinder is installed at the lower end of the connecting sleeve, and the cylindrical pin is located within the connecting sleeve. A detection window is provided on the side wall of the connecting sleeve, and a proximity switch is installed in the detection window. The proximity switch is used to detect the movement distance of the cylindrical pin. The connecting sleeve provides guidance and protection for the cylindrical pin, ensuring accurate and stable positioning. The proximity switch detects the movement distance of the cylindrical pin in real time, providing feedback on whether the positioning is in place, thus achieving automated monitoring of the positioning status.

[0014] As a preferred implementation of a material turnover system suitable for mixed-line processing, the bottom of the material tray is equipped with an electronic tag, and the non-processing bed is also equipped with an identification proton capable of reading the electronic tag. Through the cooperation of the electronic tag and the identification device, product information and processing status on the material tray can be automatically identified, laying the foundation for information management of multiple types of materials in mixed-line processing and improving production scheduling efficiency and intelligence.

[0015] As a preferred implementation of a material turnover system suitable for mixed-line processing, the processing bed is provided with multiple, and / or the non-processing bed is provided with multiple. Multiple processing beds can correspond to multiple processing devices, and multiple non-processing beds can expand the material turnover buffer space. Through system linkage, parallel turnover of multiple devices and multiple pallets can be achieved, adapting to the production needs of multiple varieties and multiple batches in mixed-line processing, further improving the flexibility and efficiency of the overall production process.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: This solution achieves the universality of the bed and pallet through the cooperation of the machining bed, non-machining bed, material tray and material trolley, breaking the limitation of the material tray corresponding to a single device, effectively improving material turnover efficiency, and adapting to the needs of mixed-line processing; the push-pull mechanism of gear and rack meshing improves the automation and accuracy of transfer, and the slide plate with telescopic components can flexibly adjust the push-pull range and avoid equipment interference; the hidden drive motor design reduces space occupation and extends equipment life; and the two sets of reverse push-pull mechanisms of the non-machining bed... The structure further enhances the flexibility of material scheduling and shortens turnaround time. At the same time, the chute roller design reduces transfer friction resistance and equipment wear. The hydraulic cylinder driven positioning mechanism, combined with connecting sleeve guidance and proximity switch monitoring, ensures accurate and stable pallet positioning and avoids processing accuracy deviations. The cooperation of electronic tags and identification devices enables information management of multiple types of materials and improves the intelligence of scheduling. The setting of multiple processing and non-processing positions on the bed can expand the buffer space and support the parallel turnover of multiple devices, fully meeting the needs of mixed-line processing of multiple varieties and multiple batches of production, taking into account efficiency, accuracy, stability and flexibility.

[0023] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions of this patent will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1-3 As shown, a material handling system suitable for mixed-line processing includes a processing bed 1, a non-processing bed 2, a material tray 3, and a material trolley 4. Both the processing bed 1 and the non-processing bed 2 are equipped with a push-pull mechanism 5 and a first guide rail 6. The material tray is equipped with a traction member 22 that cooperates with the push-pull mechanism 5 and a groove 8 that cooperates with the first guide rail 6. Both the processing bed 1 and the non-processing bed 2 are also equipped with a positioning mechanism 13 for positioning the material tray 3. The material trolley 4 is equipped with a second guide rail 7 that cooperates with the groove 8. Multiple processing beds 1 and / or multiple non-processing beds 2 are provided, such as... Figure 4 As shown, this solution can form different system layouts by setting any number of processing beds and non-processing beds. The material trolley 4 is used to transfer the material pallet 3, breaking the limitation of the material pallet corresponding to a single device, effectively improving the material turnover efficiency, and adapting to the needs of mixed-line processing.

[0025] Specifically, on the processing bed 1, one set of push-pull mechanisms 5 is provided, located at the edge of the processing bed 1. The opposite side of this edge is usually set as a processing device, so material pallet transfer is not performed. On the non-processing bed 2, two sets of push-pull mechanisms 5 are provided, and the two sets of push-pull mechanisms 5 are respectively located at one opposite side of the non-processing bed 2. The extension directions of the telescopic components of the two sets of push-pull mechanisms 5 are opposite, thereby enabling bidirectional transfer of material pallets between different material carts or different beds, increasing efficiency.

[0026] The push-pull mechanism 5 includes a slide plate 10, which is slidably mounted on the machining bed 1 and the non-machining bed 2. A telescopic component 11 is provided between the slide plate 10 and the corresponding machining bed 1 or non-machining bed 2. The telescopic component 11 can be a cylinder, hydraulic cylinder, or other components. The telescopic direction of the telescopic component 11 is the same as the extension direction of the first guide rail 6. A drive gear 9 and a drive motor 23 are mounted on the slide plate 10. The drive motor 23 is mounted on the bottom surface of the slide plate 10. The output shaft of the drive motor 23 passes through the bottom surface of the slide plate 10 and is mounted on the drive gear 9. The drive gear 9 is located at the edge of the upper surface of the corresponding machining bed 1 or non-machining bed 2 and is adapted to it. The traction member 22 is a rack, at least one end of which protrudes from the side edge of the material tray 3 and can mesh with the drive gear 9.

[0027] When transferring material pallet 3, telescopic component 11 extends, causing drive gear 9 to initially mesh with rack and pinion. Then drive motor 23 starts, and drive gear 9 rotates accordingly, pulling material pallet 3 back or pushing it out.

[0028] Furthermore, the bottom of the chute 8 is provided with a plurality of rollers 12, which are arranged along the length of the chute 8. The rollers 12 can roll in contact with the top surfaces of the first guide rail 6 and the second guide rail 7, which can significantly reduce the frictional resistance of the material pallet during the transfer process, reduce the power consumption of the push-pull mechanism, and at the same time avoid hard wear between the chute and the guide rail, thus extending the service life of the equipment.

[0029] like Figure 3 As shown, the positioning mechanism 13 includes a connecting sleeve 17 and a hydraulic cylinder 14. The connecting sleeve 17 is vertically installed in the corresponding machining bed 1 or non-machining bed 2. The cylinder body of the hydraulic cylinder 14 is installed at the lower end of the connecting sleeve 17. The telescopic rod end of the hydraulic cylinder 14 is provided with a cylindrical pin 15, which is located in the connecting sleeve 17. The bottom of the material tray 3 is provided with a pin hole 16, which can be inserted into the pin hole 16. The side wall of the connecting sleeve 17 is provided with a detection window 18, in which a proximity switch 19 is installed. The proximity switch 19 is used to detect the movement distance of the cylindrical pin 15, and can provide feedback on whether the positioning is in place, thereby realizing automated monitoring of the positioning status.

[0030] To enhance the intelligence of this system, the bottom of the material tray 3 is equipped with an electronic tag 20 (such as an RFID tag), and the non-processing bed 2 is also equipped with an identification proton 21 that can read the electronic tag. For example, the electronic tag 20 stores the processing technology of the material currently carried by the material tray 3. After the identification proton 21 reads the information of the electronic tag 20, the industrial control system can control the material trolley to transport the material tray 3 to the corresponding processing bed (corresponding to a specific processing technology).

[0031] As can be seen from the above embodiments, the advantages of this utility model are as follows: This solution achieves the universality of the bed and pallet through the cooperation of the processing bed, non-processing bed, material pallet and material trolley, breaking the limitation of the material pallet corresponding to a single device, effectively improving material turnover efficiency, and adapting to the needs of mixed-line processing; the push-pull mechanism of gear and rack meshing improves the automation and accuracy of transfer, and the slide plate with telescopic components can flexibly adjust the push-pull range and avoid equipment interference. The hidden drive motor design reduces space occupation and extends equipment life. The two sets of reverse push-pull mechanisms of the non-processing bed further enhance the flexibility of material scheduling and shorten the turnaround waiting time; at the same time, the chute roller design reduces the frictional resistance of transfer and equipment wear, and the positioning mechanism driven by the hydraulic cylinder, combined with the connecting sleeve guide and proximity switch monitoring, ensures accurate and stable pallet positioning and avoids processing accuracy deviation. The cooperation of electronic tags and identification devices realizes information management of multi-variety materials and improves the intelligence of scheduling. The setting of multiple processing and non-processing bed can expand the buffer space and support the parallel turnover of multiple devices, fully meeting the needs of multi-variety and multi-batch production in mixed-line processing, taking into account efficiency, accuracy, stability and flexibility.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use this patent. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this patent. Therefore, this patent is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
