Description

Technical Field

[0001] This utility model relates to the field of sheet metal storage technology, and in particular to a sheet metal raw material weighing device adapted to a single tower shelf for sheet metal storage. Background Technology

[0002] As my country's sheet metal processing industry accelerates its transformation towards intelligent manufacturing, material storage and transportation systems centered on automated storage and retrieval systems (AS / RS) have become a key direction for production line upgrades. Among these, sheet metal storage systems employing single-tower storage units combined with elevators and inlet / outlet conveying devices are highly favored by the market due to their significant advantages such as small footprint and high degree of automation. However, existing elevators and single-tower storage units have maximum load-bearing limitations in their design. If the sheet metal raw materials are overweight, it will trigger an overload alarm on the elevator, causing it to stop and severely disrupting production continuity. Furthermore, overload operation poses a serious threat to the structural strength and stability of the storage unit. To ensure that the sheet metal raw materials fed into the storage unit are not overweight, a solution is often adopted that involves independently installing weighing devices outside the production line. However, this solution occupies additional space, is costly, and makes information exchange and safety interlocking with the automated storage unit inconvenient. Therefore, we propose a sheet metal raw material weighing device adapted to a single-tower sheet metal storage unit. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a sheet metal raw material weighing device adapted to a single-tower sheet metal storage warehouse. This invention solves the problem that existing elevators and single-tower storage warehouses have maximum load-bearing limitations in their design. If the sheet metal raw materials are overweight, it will trigger an overload alarm on the elevator, causing it to stop and severely disrupting production continuity. Furthermore, overload operation poses a serious threat to the structural strength and stability of the storage warehouse. To ensure that the sheet metal raw materials fed into the storage warehouse are not overweight, a solution is often adopted to independently install a weighing device outside the production line. However, this solution occupies additional space, is costly, and suffers from inconvenience in information exchange and safety interlocking with the automated storage warehouse.

[0004] This utility model discloses a sheet metal raw material weighing device adapted for a single-tower sheet metal storage warehouse. It includes a support frame with multiple equidistantly arranged trays. A crossbeam is located at both ends of one side of the support frame. A drive motor is located on the side of one crossbeam away from the support frame. A shaft is located between two crossbeams, with a drive sprocket assembly at both ends of the shaft. A chain is mounted on the drive sprocket assembly, with the end of the chain away from the support frame fixedly connected to the crossbeam. A lifting platform is located at the lower end of the support frame near the crossbeam. Both sides of the lifting platform are equipped with driven sprocket assemblies matching the drive sprocket assembly. A chain connecting block is located on the crossbeam on one side of the drive sprocket assembly. The end of the chain away from the drive sprocket assembly is fixedly connected to the chain connecting block via the driven sprocket assembly. A spoke-type pressure sensor is located below the chain connecting block. Sheet metal raw materials are placed on top of the lifting platform.

[0005] In the above scheme, an adjustment shim is provided between the spoke-type pressure sensor and the crossbeam.

[0006] In the above scheme, reinforcing bars are provided on both sides of the lifting platform.

[0007] In the above scheme, guide rollers are provided on both sides of the lifting platform.

[0008] In the above scheme, an electrical control system is provided on one side of the support frame.

[0009] In the above scheme, four mounting bolts are arranged in a matrix at each of the four corners below the support frame.

[0010] In the above scheme, a transmitter is provided above the support frame on the side near the lifting platform.

[0011] The advantages and beneficial effects of this utility model are as follows: This utility model provides a sheet metal raw material weighing device adapted to a single-tower sheet metal storage warehouse. The drive motor drives the shaft to rotate, and the drive sprocket group also rotates through the transmission of the shaft. When the drive sprocket group rotates, it can drive the chain. Through the cooperation between the chain and the driven sprocket group, the lifting platform can move vertically. At the same time as the lifting platform moves, the weight of the lifting platform and the sheet metal raw material acts on the spoke-type pressure sensor, so the spoke-type pressure sensor can weigh the sheet metal raw material. The transmitter can receive and process the electrical signal collected from the spoke-type pressure sensor and convert it into a 4-20mA current signal, which is then transmitted to the electrical control system for further data processing. This type of weighing device has a high degree of automation, effectively preventing abnormal equipment shutdowns caused by overweight raw materials and the impact on the structural strength and stability of the material storage, ensuring equipment safety and production continuity. It eliminates the need for separate weighing equipment outside the production line, reducing the floor space required for the production line. It can be widely used in sheet metal storage single-tower warehouses and other material storage and transportation scenarios with similar lifting structures and weighing requirements.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-4 As shown, this utility model is a sheet metal raw material weighing device adapted to a single-tower sheet metal storage warehouse. It includes a support frame 1, on which multiple equidistantly arranged trays 2 are mounted. The trays 2 can store heavy finished sheet metal raw materials 13. A crossbeam 3 is located at both ends of one side of the support frame 1. A drive motor 4 is located on the side of one crossbeam 3 away from the support frame 1. A shaft 5 is located between two crossbeams 3, with both ends of the shaft 5 movably connected to the crossbeams 3 via bearings. The rotating shaft of the drive motor 4 passes through the crossbeams 3 and is fixedly connected to the shaft 5. Both ends of the shaft 5 are equipped with drive sprocket sets 6, on which chains 7 are mounted. The drive sprocket sets 6 and chains 7 mesh with each other. The end of the chain 7 away from the support frame 1 is fixedly connected to the crossbeam 3. A lifting platform 8 is located at the lower end of the support frame 1 near the crossbeams 3. Both sides of the lifting platform 8 are equipped with driven sprocket sets 9 that match the drive sprocket sets 6. The sprocket assembly 9 and the chain 7 mesh with each other. A chain connecting block 12 is provided on the crossbeam 3 on one side of the driving sprocket assembly 6. The end of the chain 7 away from the driving sprocket assembly 6 is fixedly connected to the chain connecting block 12 through the driven sprocket assembly 9. A spoke-type pressure sensor 10 is provided below the chain connecting block 12. Sheet metal raw material 13 is placed on the lifting platform 8. When the drive motor 4 is working, the drive motor 4 drives the shaft 5 to rotate. Through the transmission of the shaft 5, the driving sprocket assembly 6 also rotates. When the driving sprocket assembly 6 rotates, it can drive the chain 7. Through the cooperation between the chain 7 and the driven sprocket assembly 9, the lifting platform 8 can move vertically. While the lifting platform 8 is moving, the weight of the lifting platform 8 and the sheet metal raw material 13 acts on the spoke-type pressure sensor 10, so the spoke-type pressure sensor 10 can weigh the sheet metal raw material 13.

[0020] An adjusting shim 11 is provided between the spoke-type pressure sensor 10 and the crossbeam 3, and the height of the two spoke-type pressure sensors 10 can be adjusted by adjusting the shim 11.

[0021] The lifting platform 8 is equipped with reinforcing rods 14 on both sides, which effectively increases the overall structural strength of the lifting platform 8.

[0022] Guide rollers 15 are provided on both sides of the lifting platform 8. The guide rollers 15 are in contact with the side of the support frame 1, so that the guide rollers 15 can roll on the support frame 1. Through the cooperation between the guide rollers 15 and the support frame 1, the movement stability of the lifting platform 8 is effectively improved.

[0023] The support frame 1 is equipped with an electrical control system 16 on one side. The electrical control system 16 includes electrical components such as PLC, contactor, circuit breaker, and frequency converter. The electrical control system 16 can be used to perform power control, protection and logic operations on the weighing device.

[0024] The support frame 1 has four mounting bolts 17 arranged in a matrix at each of its four corners, which can be used to fix the balancing device in place.

[0025] The support frame 1 is equipped with a transmitter 18 on the side near the lifting platform 8. The transmitter 18 can accept and process the electrical signal collected from the spoke pressure sensor 10 and convert it into a 4-20mA current signal, which is then transmitted to the electronic control system 16 for further data processing.

[0026] Specifically, in this invention, when the drive motor 4 is working, it drives the shaft 5 to rotate. Through the transmission of the shaft 5, the drive sprocket assembly 6 also rotates. When the drive sprocket assembly 6 rotates, it drives the chain 7. Through the cooperation between the chain 7 and the driven sprocket assembly 9, the lifting platform 8 can move vertically. While the lifting platform 8 moves, the weight of the lifting platform 8 and the sheet metal raw material 13 acts on the spoke-type pressure sensor 10, thereby allowing the spoke-type pressure sensor 10 to weigh the sheet metal raw material 13. The transmitter 1... The lifting platform 8 can accept and process electrical signals collected from the spoke-type pressure sensor 10, convert them into 4-20mA current signals, and transmit them to the electrical control system 16 for further data processing. The electrical control system 16 includes electrical components such as PLC, contactor, circuit breaker, and frequency converter. Through the electrical control system 16, the weighing device can be electrically controlled, protected, and subjected to logic operations. The guide roller 15 is in contact with the side of the support frame 1, so that the guide roller 15 can roll on the support frame 1. Through the mutual cooperation between the guide roller 15 and the support frame 1, the movement stability of the lifting platform 8 is effectively improved.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
