Description

Technical Field

[0001] The present invention relates to the technical field of high-speed wire production, and in particular to a Stelmor roller table control system and method for high-speed wire production. Background Art

[0002] In the steel rolling high-speed wire production workshop, the wire laying machine equipment lays wire onto the Stelmor air-cooled wire roller, and the wire is transported to the collection drum for collection via 14 sections of air-cooled rollers. Due to the fast production pace of the wire workshop and the tight steel-out interval, the head of the last wire often presses the tail of the previous wire when laying wire, resulting in irregular circles of material at the tail of the wire that cannot be adjusted manually. The wire cannot be cut off before it is transported to the collection drum, resulting in the wire being unable to be collected in sequence on the collection drum, causing steel to get stuck on the roller, resulting in defective products, and affecting the yield and qualified rates. When producing wire varieties with faster air-cooled roller speeds, the tail-cutting personnel in front of the collection drum often do not have time to cut off the irregular part of the tail of the wire, resulting in steel getting stuck in the collection drum and the material cannot be collected. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a high-speed wire production Stelmor roller control system and method. A gear lever signal sensing device is arranged at the fourth-to-last roller to sense the wire passing signal. When the initial speed of the third-to-last roller is greater than 0.8 m / s, the speed is automatically reduced to V3 and restored after 5 seconds, so as to cut off the irregular loop at the tail of the wire, thereby effectively improving the yield and qualified rate.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a high-speed wire production Stelmor roller control system, comprising:

[0005] The first roller speed setting unit is used to set the initial speed of the first roller to V0;

[0006] A wire tail signal detection unit, used to detect a wire tail signal;

[0007] The first roller speed adjustment unit is used to automatically increase the first roller speed to V1 when the wire tail signal is detected;

[0008] The gear lever signal sensing device includes a rotatable gear lever and a signal proximity switch, and is used to sense the falling edge trigger signal generated when the wire passes through the fourth roller from the bottom;

[0009] The speed selection function unit is used to determine whether to enable the speed reduction function according to the initial speed V2 of the third-to-last roller conveyor when the gear lever signal sensing device detects that the signal disappears;

[0010] The speed reduction execution unit is used to automatically reduce the speed of the third-to-last roller to V3 when the speed reduction function is enabled, and automatically restore to V2 after 5 seconds.

[0011] In a second aspect, the present invention provides a method for producing a Stelmor roller table control system using the high-speed wire rod according to the first aspect, comprising the following steps:

[0012] The initial speed of the first roller is set to V0 through the first roller speed setting unit;

[0013] The wire tail signal is detected by the wire tail signal detection unit. When it is detected that the wire tail passes through the laying machine, the speed of the first section roller is automatically increased to V1 by the first section roller speed adjustment unit;

[0014] After the wire passes through the first roller, the head signal of the next wire is detected. If the wire tail signal detection unit detects that the head of the next wire passes through the laying machine, the speed adjustment unit of the first roller automatically restores the speed V1 of the first roller to V0;

[0015] The signal of the wire passing through is sensed by the lever signal sensing device at the fourth roller from the end. When the tail of the wire passes through the fourth roller from the end, the signal of the sensing device disappears, forming a falling edge trigger signal, and proceeding to the next step;

[0016] The speed selection function unit detects the initial speed V2 of the third-to-last roller. If V2 is greater than 0.8 m / s, the speed reduction function is enabled, and the speed of the third-to-last roller is automatically reduced to V3 through the speed reduction execution unit, and automatically restored to V2 after 5 seconds.

[0017] If V2 is not greater than 0.8 m / s, keep V2 unchanged.

[0018] Furthermore, in the step of accelerating the first roller conveyor to V1, the calculation formula of V1 is V1=V0×M, and the value range of M is 1.2 to 1.4.

[0019] Furthermore, in the step of reducing the speed of the third-to-last roller to V3, the calculation formula of V3 is V3=V2×N, and the value range of N is 0.6-0.8.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention sets a lever signal sensing device at the fourth-to-last roller conveyor. When the wire passes through, the rotatable lever senses the falling edge trigger signal generated when the wire passes through at the fourth-to-last roller conveyor. The proximity switch senses the signal to accurately control the speed of the third-to-last roller conveyor, thereby providing sufficient time for cutting off the irregular loop at the tail of the wire, effectively reducing the generation of defective products and improving the yield and qualified rate of the products.

[0022] (2) The present invention can ensure smooth transmission of the wire on the roller by automatically detecting the wire tail signal and timely adjusting the speed of the first roller, thereby reducing the steel jamming phenomenon caused by the irregularity of the wire tail, thereby improving the continuity and efficiency of the production line.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The embodiment of the present invention provides a high-speed wire production Stelmor roller control system, comprising:

[0032] The first roller speed setting unit is used to set the initial speed of the first roller to V0;

[0033] A wire tail signal detection unit, used to detect a wire tail signal;

[0034] The first roller speed adjustment unit is used to automatically increase the first roller speed to V1 when the wire tail signal is detected;

[0035] Shift lever signal sensing device, such as Figure 4 As shown, it includes a rotatable lever 1 and a signal proximity switch 2. One end of the rotatable lever 1 is connected to the signal proximity switch 2, and the other end is used to sense the falling edge trigger signal generated when the wire passes through the fourth roller from the bottom. When the wire passes, the rotatable lever is pushed to make the signal proximity switch sense the signal.

[0036] The speed selection function unit is used to determine whether to enable the speed reduction function according to the initial speed V2 of the third-to-last roller conveyor when the gear lever signal sensing device detects that the signal disappears;

[0037] The speed reduction execution unit is used to automatically reduce the speed of the third-to-last roller to V3 when the speed reduction function is enabled, and automatically restore to V2 after 5 seconds.

[0038] As an example, Figure 1-3 As shown, a method for producing a Stelmor roller control system using high-speed wire rods comprises the following steps:

[0039] The initial speed of the first roller is set to V0 through the first roller speed setting unit;

[0040] The wire tail signal is detected by the wire tail signal detection unit. When it is detected that the wire tail passes through the laying machine, the speed of the first section roller is automatically increased to V1 by the first section roller speed adjustment unit;

[0041] After the wire passes through the first roller, the head signal of the next wire is detected. If the wire tail signal detection unit detects that the head of the next wire passes through the laying machine, the speed adjustment unit of the first roller automatically restores the speed V1 of the first roller to V0;

[0042] The signal of the wire passing through is sensed by the lever signal sensing device at the fourth roller from the end. When the tail of the wire passes through the fourth roller from the end, the signal of the sensing device disappears, forming a falling edge trigger signal, and proceeding to the next step;

[0043] The speed selection function unit detects the initial speed V2 of the third-to-last roller. If V2 is greater than 0.8 m / s, the speed reduction function is enabled, and the speed of the third-to-last roller is automatically reduced to V3 through the speed reduction execution unit, and automatically restored to V2 after 5 seconds.

[0044] If V2 is not greater than 0.8 m / s, keep V2 unchanged.

[0045] Specifically, in the step of accelerating the first roller conveyor to V1, the calculation formula of V1 is V1=V0×M, and the value range of M is 1.2 to 1.4, preferably, 1.3.

[0046] Furthermore, in the step of reducing the speed of the third-to-last roller to V3, the calculation formula of V3 is V3=V2×N, and the value range of N is 0.6 to 0.8, preferably, 0.7.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
