Description

Technical Field

[0001] This invention relates to the field of production line technology, and more specifically, to a production line for processing multiple products. Background Technology

[0002] Resin sand intelligent production line is an advanced casting technology that has emerged in response to the development of modern manufacturing. With the continuous development of industry, the requirements for the quality, precision and production efficiency of castings are getting higher and higher. Traditional molding methods are gradually becoming unable to meet the market's demand for high-quality and complex-shaped castings. In the fields of automobiles, machinery, aerospace and other industries, a large number of high-quality and diverse castings are needed to ensure the performance and reliability of products.

[0003] Currently, many production lines face the need to produce a variety of products, which requires the use of molds for different products. In traditional technology, even with a large production volume, different molds need to be manually adjusted step by step, resulting in high labor costs and low safety. Therefore, automated warehouses have emerged in production lines to store and transport the molds required.

[0004] However, most automated storage and retrieval systems (AS / RS) in production lines are currently operated by equipment such as palletizers, which simply store various molds in designated locations within the AS / RS. The molds are not stable enough in these locations, and due to worker misoperation, molds may fall or become misplaced, making them difficult to retrieve. Summary of the Invention

[0005] This invention proposes a production line for multi-product processing, which solves the problem that the position of molds in the automated warehouse within the production line cannot be guaranteed in related technologies.

[0006] The technical solution of the present invention is as follows: A multi-product processing production line, comprising: Equipment line; An automated storage and retrieval system (AS / RS) is stationary relative to the equipment line and has several storage locations. Two limiting plates are movable within the storage location, forming a limiting area between them. After the two limiting plates move, they move closer to or further away from each other to restrict the mold within the limiting area. A palletizer is movable relative to the automated warehouse. The palletizer has an operating support part. After the palletizer moves, the operating support part is used to push the two limiting plates and support the transfer of the mold.

[0007] As a further technical solution, it also includes: A support plate is fixedly installed at the bottom of the storage location. Two limiting plates pass through both ends of the support plate. The limiting plates are movably installed on the support plate, and the limiting area is formed between the two limiting plates and the support plate. A scissor frame, wherein two limiting plates are respectively connected to both ends of the scissor frame.

[0008] As a further technical solution, the operating support has a rack, the scissor frame is located below the support plate, the scissor frame has a central gear portion, the central gear portion passes through the support plate and is located within the limiting area, after the operating support moves, the rack engages or disengages with the central gear portion, for pushing the two limiting plates through the scissor frame.

[0009] As a further technical solution, it also includes: A top plate is disposed on the limiting plate. After the limiting plate moves, the top plate is used to release the restriction on the top of the mold. Four vertex clamping members are movably disposed on the support plate and located at the bottom of the limiting area. After the four vertex clamping members move, they move closer to or further away from each other to release the limiting effect on the bottom of the mold.

[0010] As a further technical solution, the four vertex clamping members are arranged in a matrix. The vertex clamping members have guide slopes, and the limiting plates have guide pushers. After the two limiting plates move away from each other, the top plate is first driven to release the limiting effect on the top of the mold, and then the guide pushers push the guide slopes.

[0011] As a further technical solution, there are two guide pushers, which are located between two adjacent vertex clamping members. The guide pushers are triangular, and the top of the guide pushers and the top of the guide slope are both lower than the top of the operating support.

[0012] As a further technical solution, the vertex clamping member has a right-angle limiting surface and a downward slope. The downward slope is located below the right-angle limiting surface, and the bottom surface of the downward slope is higher than the top surface of the operating support. After the four vertex clamping members move away from each other, they are used to release and slide the mold onto the operating support.

[0013] As a further technical solution, the support plate also has a guide groove, and the vertex clamping member is movably disposed in the guide groove, the length direction of the guide groove being arranged along the diagonal of the mold.

[0014] As a further technical solution, it also includes: An elastic element is provided, with its two ends connected to the support plate and the vertex clamping member, respectively. The elastic element is located in the guide groove and provides a force that brings the four vertex clamping members closer to each other.

[0015] The working principle and beneficial effects of this invention are as follows: In this invention, in the resin sand molding production line, the resin hardening process requires a certain amount of time, and the mold opening cost is very high. To improve equipment uptime, multiple different products need to be produced simultaneously. Since each product has different production quantities, sizes, and shapes, different sand boxes are required. The production line frequently needs to change molds and sand boxes, which reduces production line efficiency. Therefore, a three-dimensional warehouse is needed to store molds and empty sand boxes, reducing manual labor intensity and downtime caused by human error. A three-dimensional warehouse and intelligent system are used for production scheduling, allowing different products of the same material to be produced in the same batch.

[0016] The automated storage and retrieval system (AS / RS) in the resin sand intelligent production line includes the following key steps during operation: warehousing process, storage operation, inventory operation, outbound process, and information management and interaction. It completely replaces the manual mold allocation operation, greatly reducing labor costs and ensuring a certain level of safety. AS / RS are divided into various types, such as beam-type AS / RS, drive-in AS / RS, or automated cabinet-type AS / RS, etc. Each type of AS / RS has its own defects, but all AS / RS have a common problem: the palletizing machine completes the operation, simply storing various molds in the designated storage locations of the AS / RS. The molds are not stable enough in the storage location, and due to human error, the molds may fall or become misplaced in the storage location, making them difficult to retrieve.

[0017] To solve the above problems, a limiting plate for the limiting mold is installed in the storage location and linked to the operating support part of the palletizer. When the operating support part moves into the storage location to support or store the mold, it will first interact with the limiting plate to release the mold within the limiting area, and then it can be successfully taken away or stored.

[0018] Specifically, the automated storage and retrieval system (AS / RS) is integrated within the production line, making full use of vertical space and providing a large number of storage locations within a limited footprint. Two limiting plates move within the storage locations and can be adjusted according to molds of different sizes, forming a limiting area that precisely restricts the molds to specific positions. This not only ensures the stability of the molds during storage, preventing damage caused by shaking or displacement, but also facilitates the accurate operation of the subsequent palletizer. The flexible palletizer's operating support can first push the limiting plates to adjust their position, and then support and transfer the molds. This sequential process enables the rapid and accurate transfer of molds between the AS / RS and the production line. This efficient transfer method significantly shortens mold handling time, improves production efficiency, and, in multi-product processing scenarios, can quickly respond to the production needs of different products, promptly delivering the required molds to designated locations, reducing production waiting time, and improving the overall operating efficiency of the production line.

[0019] The automated warehouse's location management system can monitor the storage location and status of molds in real time, facilitating inventory management for businesses. Managers can quickly locate the required molds, accurately track inventory quantities and usage, and promptly allocate and replenish them. This helps improve the accuracy and efficiency of inventory management, reduce inventory costs, and avoid production delays caused by lost or poorly managed molds. Attached Figure Description

Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Reference Figures 1-10The first embodiment of the present invention proposes a multi-product processing production line, comprising: an equipment line 1; an automated storage and retrieval system (AS / RS) 2, which is stationary relative to the equipment line 1 and has several storage locations 201; two limiting plates 3, which are movable within the storage locations 201, forming a limiting area 301 between them; and a palletizer 5, which is movable relative to the AS / RS 2 and has an operating support part 501. After the palletizer 5 moves, the operating support part 501 is used to push the two limiting plates 3 and support and transfer the mold 4.

[0028] In resin sand molding production lines, resin curing takes time, and mold making costs are high. To improve equipment uptime, multiple different products need to be produced concurrently. Since each product has different production quantities, sizes, and shapes, different sand boxes are required. This leads to frequent mold and sand box changes, reducing production line efficiency. Therefore, automated storage and retrieval systems (AS / RS) are needed to store molds and empty sand boxes, reducing manual labor and downtime due to human error. AS / RS and intelligent systems are used for production scheduling, allowing different products of the same material to be produced in the same batch.

[0029] During production, the production line includes preparation stations, box-fitting stations, sand filling, compaction stations, hardening stations, mold-removal stations, shaping stations, flow coating stations, surface drying stations, and an automated storage area. These stations are connected by roller conveyors and transfer vehicles. Therefore, an automated storage system is set up in the molding department, mainly to store molds and empty sand boxes. Production scheduling is planned by combining the automated storage system with an intelligent system, producing different products of the same material in the same batch. Specifically, firstly, according to the instructions of the production line's intelligent system, the mold is taken out of the automated storage system and transported by a transfer vehicle to the preparation station. At the preparation station, mold cleaning, parting agent spraying, and chill placement are carried out. Then, the prepared mold moves forward to the box-fitting station, while the empty sand box is taken out of the automated storage system and automatically fitted onto the mold. After that, the mold with the sand box fitted is transported by a transfer vehicle to the molding station, where sand filling and molding are performed. The molded sand box then moves forward. The sand mold will gradually harden over time. Then, the upper mold with the sand box attached is transported by a transfer vehicle to the molding station, where sand is filled and shaped. The molded sand box moves forward, and the sand mold will gradually harden over time. After hardening, the sand box moves forward to the demolding station, where it is automatically demolded by a flipping demolding machine. The demolded sand mold then moves forward, and during this process, the mold is repaired. The demolded mold is then transported by a transfer vehicle to the preparation station to begin the next work cycle, while the intelligent production line system increments the number of molds molded. When the number of molds molded reaches the requirements of the intelligent production line system, the demolded mold automatically enters the automated storage and retrieval system. Simultaneously, a new mold is retrieved from the automated storage and retrieval system to begin the next work cycle. The repaired sand mold then moves forward to the flow coating station, where the surface of the sand mold is flow coated. Finally, the flow-coated sand mold moves forward to the surface drying station to allow the coating to dry. The addition of automated storage and retrieval systems (AS / RS) has significantly reduced labor intensity and increased productivity in the entire resin sand molding production line. However, the AS / RS currently has some problems. To address these issues, the following improvements are proposed.

[0030] Specifically, in this embodiment, the automated storage and retrieval system 2 in the resin sand intelligent production line includes the following key steps during operation: warehousing process, storage operation, inventory operation, outbound process, and information management and interaction. It completely replaces the manual allocation of molds 4, greatly reducing labor costs and ensuring a certain level of safety. Automated storage and retrieval systems 2 are divided into various types, such as beam-type automated storage and retrieval systems 2, drive-in automated storage and retrieval systems 2, or automated cabinet-type automated storage and retrieval systems 2, etc. Each type of automated storage and retrieval system 2 has its own defects, but all automated storage and retrieval systems 2 have a common problem: the palletizer 5 completes the operation, only storing various molds 4 in the designated storage positions 201 of the automated storage and retrieval system 2. The molds 4 are not stable enough in this environment, and due to human error, the molds 4 in storage positions 201 may fall or become misplaced, making them difficult to retrieve.

[0031] To solve the above problems, a limiting plate 3 for the limiting mold 4 is installed in the storage location 201 and linked with the operating support part 501 of the palletizer 5. When the operating support part 501 moves into the storage location 201 to support or store the mold 4, it will first interact with the limiting plate 3 to release the mold 4 within the limiting area 301, and then it can be successfully taken away or stored.

[0032] Specifically, the automated storage and retrieval system 2 is installed within the equipment line 1, making full use of vertical space and providing a large number of storage locations 201 within a limited area. Two limiting plates 3 move within the storage locations 201 and can be adjusted according to molds 4 of different sizes. The resulting limiting area 301 can precisely confine the molds 4 within the limiting area 301. This not only ensures the stability of the molds 4 during storage and prevents damage caused by shaking or displacement, but also facilitates the accurate operation of the subsequent palletizer 5. The flexible operating support part 501 of the palletizer 5 can linearly push the limiting plates 3 to adjust their position and then support and transfer the molds 4. The sequential transfer of these steps enables the rapid and accurate transfer of the molds 4 between the automated storage and retrieval system 2 and the equipment line 1. This efficient transfer method greatly shortens the handling time of the molds 4, improves production efficiency, and, in multi-product processing scenarios, can quickly respond to the production needs of different products, promptly delivering the required molds 4 to the designated location, reducing production waiting time, and improving the overall operating efficiency of the production line.

[0033] The automated warehouse 2's location management system 201 can monitor the storage location and status of molds 4 in real time, facilitating inventory management for the enterprise. Managers can quickly query the location of required molds 4 through the system, accurately grasp the inventory quantity and usage, and promptly allocate and replenish molds 4. This helps improve the accuracy and efficiency of inventory management, reduce inventory costs, and avoid production delays caused by lost or poorly managed molds 4.

[0034] Furthermore, it also includes: a support plate 6, which is fixedly installed at the bottom of the storage location 201, with two limiting plates 3 passing through both ends of the support plate 6, and the limiting plates 3 being movably installed on the support plate 6, forming a limiting area 301 between the two limiting plates 3 and the support plate 6; and a scissor frame 7, with two limiting plates 3 connected to both ends of the scissor frame 7.

[0035] In this embodiment, the support plate 6 is welded to the bottom of the storage location 201, providing a stable support foundation for the limiting plate 3. In actual production, when the mold 4 is placed in the limiting area 301, the support plate 6 can bear the weight of the mold 4, ensuring stability and preventing the limiting plate 3 from tilting or deforming. At the same time, the limiting plate 3 is penetrated by the support plate 6 and moves on it. Furthermore, a scissor frame 7 is welded between the two limiting plates 3, replacing the drive form such as adding a cylinder. The scissor frame 7 is added between the two limiting plates 3, reducing the space occupied, thereby storing more types of molds 4 in the same storage location 201; at the same time, it can also stably control their movement.

[0036] Furthermore, the operating support 501 has a rack 502, and the scissor frame 7 is located below the support plate 6. The scissor frame 7 has a central gear 701, which penetrates the support plate 6 and is located within the limiting area 301. After the operating support 501 moves, the rack 502 engages with or disengages from the central gear 701 to push the two limiting plates 3 through the scissor frame 7.

[0037] In this embodiment, the scissor frame 7 is positioned below the support plate 6 to avoid affecting the operation of the operating support 501. This is because the operating support 501 needs to contact the bottom of the mold 4 on the support plate 6 to complete the aforementioned action. To achieve the linkage between the two, the scissor frame 7 is provided with a central gear 701 at its center position, which penetrates the support plate 6 and protrudes within the limiting area 301. This facilitates engagement with the rack 502 of the moving operating support 501, causing a chain reaction in the operation of the operating support 501. This drives the scissor frame 7 to release the limiting effect of the two limiting plates 3 on the mold 4, and saves the cost of an additional power source to drive the scissor frame 7.

[0038] Furthermore, it also includes: a top plate 8, which is disposed on the limiting plate 3. After the limiting plate 3 moves, the top plate 8 is used to release the limitation on the top of the mold 4; and four vertex clamping parts 9, which are all movably disposed on the support plate 6 and are all located at the bottom of the limiting area 301. After the four vertex clamping parts 9 move, they move closer to each other or further away from each other to release the limitation on the bottom of the mold 4.

[0039] In this embodiment, in order to more stably restrict the mold 4 within the limiting area 301, it is divided into upper and lower parts. The top plate 8, which moves with the limiting plate 3, serves to restrict the top of the mold 4. The four vertex clamping parts 9, which are supported by the support plate 6 and move at the bottom of the limiting area 301, restrict the bottom of the mold 4 from the four corners. Only when both the upper and lower positions are released from restriction can the mold 4 be operated, which greatly improves safety.

[0040] Furthermore, the four vertex clamping parts 9 are arranged along the matrix. The vertex clamping parts 9 have guide slopes 901. The limiting plate 3 has guide pushers 10. After the two limiting plates 3 move away from each other, the top plate 8 is first driven to release the limiting on the top of the mold 4, and then the guide slopes 901 are pushed by the guide pushers 10.

[0041] In this embodiment, the sequence of steps is further set so that the top plate 8 first releases the restriction on the top of the mold 4, and then the four vertex clamping parts 9 release the restriction on the bottom of the mold 4. Without adding an additional power source, the above actions are completed by the movement of the mutually distancing limiting plates 3. Therefore, guide pushers 10 are welded on both limiting plates 3. Utilizing the properties of the guide slope 901, after the limiting plates 3 move to the point where the top plate 8 takes effect, the two sets of limiting plates 3 continue to move away from each other. As a result, the guide pushers 10 on the limiting plates 3 will push the four vertex clamping parts 9 through the guide slope 901 to release the restriction on the bottom of the mold 4. The guide pushers 10 need to have a certain length to ensure that the above sequence of steps is carried out.

[0042] Furthermore, there are two guide pushers 10, which are located between two adjacent vertex clamping members 9. The guide pushers 10 are triangular, and the top of the guide pushers 10 and the top of the guide slope 901 are both lower than the top of the operating support 501.

[0043] In this embodiment, guide pushers 10 are welded to both limiting plates 3. They are triangular because a set of guide pushers 10 needs to provide synchronous force between the two vertex clamping members 9. The top of the guide pushers 10 and the top of the guide slope 901 are both lower than the top of the operating support 501 to avoid interference with the mold 4 that will be supported by the operating support 501 during the entire movement process.

[0044] Furthermore, the vertex clamping member 9 has a right-angle limiting surface 902 and a downward slope 903. The downward slope 903 is located below the right-angle limiting surface 902, and the bottom surface of the downward slope 903 is higher than the top surface of the operating support 501. After the four vertex clamping members 9 move away from each other, they are used to release and slide the mold 4 onto the operating support 501.

[0045] In this embodiment, the vertex clamping member 9 is further designed with a right-angle limiting surface 902 and a downward slope 903. While releasing the mold 4, the mold 4 can be slowly slid down from a certain height onto the operating support 501. This can smoothly support the mold 4 and make it contact the bottom of the mold 4. The initial height of the mold 4 is higher than the operating support 501, and vice versa. The movement of the four vertex clamping members 9 can also clamp the mold 4 on the operating support and increase its height.

[0046] Furthermore, the support plate 6 also has a guide groove 601, and the vertex clamping member 9 is movably disposed in the guide groove 601. The guide groove 601 is arranged along the diagonal of the mold 4 in the length direction.

[0047] Furthermore, it also includes: an elastic element 11, with the support plate 6 and the vertex clamping member 9 connected at both ends of the elastic element 11 respectively. The elastic element 11 is located in the guide groove 601 and provides a force for the four vertex clamping members 9 to move closer to each other.

[0048] In this embodiment, a guide groove 601 for moving the vertex clamping member 9 is further provided on the support plate 6, which is set along the diagonal of the mold 4. This also facilitates the vertex clamping member 9 to function at the four corners of the bottom of the mold 4. At the same time, an elastic member 11 is installed in the guide groove 601 to provide a force for the four vertex clamping members 9 to move closer to each other, so as to stably clamp the mold 4 and reset after adapting to the movement of the guide push member 10.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
