Description

Technical Field

[0001] This application relates to the field of bar collection technology, and in particular to a method for improving the collection efficiency of underground cooling beds. Background Technology

[0002] Bar stock is a type of metallic material. Common types of bars include stainless steel bars, alloy steel bars, and carbon steel bars, which have important applications in machinery manufacturing, construction engineering, petrochemicals, aerospace, and other fields. Currently, finished bar stock is collected through two methods: overhead cranes and automated underground roller conveyors. However, the collection process suffers from low efficiency. Due to the lack of interlocking between the conveyor rollers, the number of packages stored per unit length of roller conveyor is small, resulting in low utilization of the conveyor rollers. Furthermore, there is a problem of bars colliding on the conveyor rollers, and there is a lack of reasonable obstacle avoidance methods. Therefore, improvements are needed. Summary of the Invention

[0003] To improve the collection efficiency of underground cooling beds for bar stock, this application provides a method for improving the collection efficiency of underground cooling beds.

[0004] This application provides a method for improving the collection efficiency of underground cold beds, which employs the following technical solution: A method for improving the collection efficiency of underground cold beds includes the following steps: The first, second, third, fourth, fifth, and sixth roller conveyors are set up in sequence, and the transmission length of each roller conveyor is confirmed. Each roller conveyor is controlled by the control console. Each roller conveyor is configured to drive independently. A grating signal is set based on the spacing of each roller conveyor segment. The spacing between two adjacent grating signals is set to a fixed value. A communication connection between the grating signal and the control console is established. The opening and closing of each roller conveyor segment is controlled based on the preset grating signal on / off rules in the control console. Lifting chains and translation chains are respectively installed on the five-section roller conveyor and the six-section roller conveyor for collecting the bar stock. An interlock is set between the five-section roller conveyor and the six-section roller conveyor, and the opening and closing of the interlock is controlled based on the working status of the two lifting chains and the on / off rules of the grating signal.

[0005] Optionally, the on / off rule of the grating signal is as follows: when two adjacent grating signals of two roller conveyors disappear at the same time, if the grating signal of the latter disappears before the grating signal of the former, the roller conveyor corresponding to the grating signal of the latter stops driving.

[0006] Optionally, a section of the roller conveyor is provided with a grating signal, which is located at the end of the section of the roller conveyor.

[0007] Optionally, a baffle is provided between the five-section roller conveyor and the six-section roller conveyor, and the interlocking is as follows: if the lifting chain corresponding to the five-section roller conveyor malfunctions and the grating signal at the end of the five-section roller conveyor detects the head of the finished package, the five-section roller conveyor continues to operate, and the lifting chain corresponding to the six-section roller conveyor is activated; if the lifting chain corresponding to the six-section roller conveyor malfunctions and there are grating signals at the end of the five-section roller conveyor and the six-section roller conveyor, the baffle protrudes and extends between the five-section roller conveyor and the six-section roller conveyor; if the translation chain malfunctions, the lifting chain stops operating synchronously.

[0008] Optionally, the first and second roller conveyors are used to receive finished product packages, with lengths of 16m and 12m respectively; the third and fourth roller conveyors are intermediate transport roller conveyors, each with a length of 30m; and the fifth and sixth roller conveyors are underground cooling bed collection roller conveyors, with lengths of 16m and 12m respectively.

[0009] Optionally, the spacing between adjacent grating signals is set to 4m.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. The method of this application can effectively improve the transfer and storage efficiency of underground collection roller conveyors by switching on and off the grating signal, reduce manual workload, reduce the probability of failure of underground collection roller conveyors, and improve operational safety. 2. Setting the spacing between adjacent grating signals to 4m, based on the grating signal on / off rules, allows the spacing between all finished product packages to be controlled between 4-8m. Under this condition, the risk of interference between finished product packages will be greatly reduced, while maximizing the storage capacity of the underground collection roller conveyor and improving collection efficiency.

[0012] Figure 2 This is a logic diagram of a method for improving the collection efficiency of underground cold beds according to an embodiment of this application. Detailed Implementation

[0013] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0014] This application discloses a method for improving the collection efficiency of underground cold beds. (Refer to...) Figure 1 and Figure 2 It includes the following steps: S1: Sequentially set up a first-section roller conveyor, a second-section roller conveyor, a third-section roller conveyor, a fourth-section roller conveyor, a fifth-section roller conveyor, and a sixth-section roller conveyor, and confirm the transmission length of each section of the roller conveyor. Each section of the roller conveyor is controlled by the control console.

[0015] S11: Section 1 and Section 2 roller conveyors are used to receive finished product packages, with lengths of 16m and 12m respectively. Section 3 and Section 4 roller conveyors are intermediate transport roller conveyors, each with a length of 30m. Section 5 and Section 6 roller conveyors are underground cooling bed collection roller conveyors, with lengths of 16m and 12m respectively.

[0016] S2: Set each roller conveyor to be a separate drive, set grating signals based on the spacing of each roller conveyor segment, set the spacing between two adjacent grating signals to a fixed value, establish a communication connection between the grating signals and the control console, and control the opening and closing of each roller conveyor segment based on the preset grating signal on / off rules in the control console.

[0017] S21: A grating signal is set at the end of a section of the roller conveyor.

[0018] S22: The spacing between adjacent grating signals is set to 4m.

[0019] S23: The on / off rules for grating signals are as follows: When two adjacent grating signals on two roller conveyors disappear at the same time, if the grating signal of the rear disappears before the grating signal of the front, the roller conveyor corresponding to the grating signal of the rear disappears first.

[0020] During implementation, a total of grating signals, numbered 1 to 26, are set. Grating signal 1 corresponds to one section of the roller conveyor; grating signals 2, 3, and 4 correspond to two sections of the roller conveyor; grating signals 5, 6, 7, 8, 9, 10, and 11 correspond to three sections of the roller conveyor; grating signals 12, 13, 14, 15, 16, 17, 18, and 19 correspond to four sections of the roller conveyor; grating signals 20, 21, 22, and 23 correspond to five sections of the roller conveyor; and grating signals 24, 25, and 26 correspond to six sections of the roller conveyor. This arrangement ensures that the spacing between all finished product packages can be controlled within 4-8 meters. This significantly reduces the risk of interference between finished product packages and increases the storage capacity of finished product packages.

[0021] Specifically, taking grating signals 1, 2, and 3 as examples, when grating signal 1 disappears, grating signal 2 disappears. If signal 1 disappears before signal 2, it means that the grating signal disappears because of the same finished product package. The roller conveyor can continue to move when grating signal 3 appears. If signal 2 disappears before signal 1, it means that there are two packages in front and behind, and the distance between the two packages is slightly large. At this time, the operation of the roller conveyor corresponding to grating signal 1 will be stopped to wait for the front finished product package to be transported, so as to prevent adjacent finished product packages from colliding. In this embodiment, the order of determining whether the roller conveyor has stopped running is carried out sequentially from the six roller conveyors to the first roller conveyor.

[0022] S3: Lifting chains and translation chains are respectively installed on the five-section roller conveyor and the six-section roller conveyor for collecting the bar stock. An interlock is set between the five-section roller conveyor and the six-section roller conveyor. The opening and closing of the interlock is controlled based on the working status of the two lifting chains and the on / off rules of the grating signal.

[0023] During implementation, both the five-section and six-section roller conveyors are equipped with lifting chains and translation chains to improve the collection efficiency of the bars. The lifting chain is an intermediate carrier connecting the roller conveyor and the chain. When it is raised, it lifts the finished product packages on the roller conveyor and transfers them to the translation chain via the chain. When it is lowered, it does not affect the movement of the finished product packages. The function of the lifting chain is to transfer the finished product packages from the roller conveyor to the translation chain, and then the translation chain serves as a temporary storage for the overhead crane to transport the collected bars.

[0024] S31: A baffle is installed between the five-section roller conveyor and the six-section roller conveyor, with the following interlocking mechanism: If the lifting chain corresponding to the five-section roller conveyor malfunctions, and the grating signal at the end of the five-section roller conveyor detects the head of the finished package, the five-section roller conveyor continues to operate, and the lifting chain corresponding to the six-section roller conveyor is activated; if the lifting chain corresponding to the six-section roller conveyor malfunctions, and there are grating signals at the end of both the five-section roller conveyor and the six-section roller conveyor, the baffle protrudes and extends between the five-section roller conveyor and the six-section roller conveyor; if the translation chain malfunctions, the lifting chain stops operating synchronously.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
