Description

Technical Field

[0001] The invention relates to a strip tail identification device, in particular to a strip tail identification device for a horizontal strip steel coil, and belongs to the technical field of intelligent control. Background Art

[0002] Strip steel, also known as steel strip, is a narrow and long steel plate manufactured by various steel rolling enterprises to meet the industrial production needs of various metal or mechanical products in different departments. The existing single-bundle production process of strip steel generally includes rolling-coiling-circumferential bundling-coding-through bundling.

[0003] Among them, the coiling process is to bend and curl the strip steel to form a rolled strip steel coil. Before completing the circumferential bundling, the tail of the strip steel coil, that is, the strip tail, will still form a certain gap with the strip steel coil body after deformation, and the position of the strip tail of each strip steel coil after coiling is random. Even for the same batch of strip steel, the position of the strip tail is not fixed after coiling. At present, manual visual inspection is usually used to identify the strip tail position, and the coiling equipment is controlled to rotate the strip tail of each strip steel coil to a relatively consistent position, so as to avoid the strip tail position when executing the subsequent coding and bundling processes to prevent coding and bundling failures.

[0004] However, the on-site working conditions of single-bundle strip packaging are complicated, which is not conducive to the physical and mental health of operators. How to realize automatic identification of the tail of the strip coil has become a major problem restricting the realization of automated single-bundle strip packaging. Summary of the invention

[0005] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a tail identification device for a horizontal strip steel coil, so as to realize automatic identification of the tail of the strip steel coil.

[0006] Technical solution: A tail identification device for a horizontal strip steel coil, comprising a base, a cylinder, a shield, an auxiliary wheel, and a travel switch, wherein the cylinder is fixed on the base, the front end opening of the shield and the rear bottom are fixedly connected to the movable end of the cylinder, there are two auxiliary wheels, which are respectively fixed on the left and right sides of the inside of the shield, and the front side of the auxiliary wheel is exposed from the front end opening of the shield, the travel switch comprises a switch body, a rotating shaft, and a tongue, the switch body is located outside the shield and fixed to the side wall of the shield, the tongue is connected to the switch body through the rotating shaft, the auxiliary wheel and the rotating shaft are parallel to the axial direction of the strip steel coil, and the front end of the tongue exceeds the front end connection line of the two auxiliary wheels, so that when the two auxiliary wheels abut against the strip steel coil, the tongue is squeezed by the strip steel coil and rotates.

[0007] The principle of the present invention is: when in use, the strip steel coil rotates clockwise along its winding direction. When the position of its tail needs to be identified, the cylinder pushes the shield close to the strip steel coil, so that the tongue and two auxiliary wheels are successively pressed against its side walls, and the tongue is squeezed and rotated to a certain angle. When identifying the tail, the tail position of the strip steel coil is first rotated to a position where it rotates relative to the two auxiliary wheels. At this time, the two auxiliary wheels press the tail tightly, and when the tail turns away from the auxiliary wheels, it hits the tongue that is in rear contact with it under the action of rebound, so that the tail position of the strip steel coil is accurately identified through the force rotation of the tongue. After identifying the tail of the strip steel coil, the strip steel coil can be controlled to stop rotating to keep the tails of all the strip steel coils in the same position, so that when executing the subsequent coding and bundling processes, the tail position is avoided to prevent coding and bundling failures. After the identification is completed, the cylinder is used to retract the identification device to prevent it from affecting the transportation of the strip steel coil.

[0008] Furthermore, it also includes a supporting mechanism, which includes a U-shaped plate, a slide rail, a slider, and a bottom plate. The opening of the U-shaped plate faces upward, the front end is fixedly connected to the rear bottom of the shield, and the movable end of the cylinder is fixed inside. The U-shaped plate wraps and protects the movable end of the cylinder; the bottom plate is fixed on the base and is located below the U-shaped plate; the slide rail is fixed on the upper surface of the bottom plate, and the extension direction of the slide rail is the same as the extension direction of the movable end of the cylinder; the slider slides on the slide rail and is fixed to the lower bottom surface of the U-shaped plate.

[0009] Preferably, a cylinder connecting head is arranged inside the U-shaped plate, and the movable end of the cylinder is connected to the cylinder connecting head via a floating joint.

[0010] Furthermore, the travel switch also includes a switch housing, which is connected from front to back and its outer wall is connected to the outer wall of the shield. The switch body and the rotating shaft are located inside the switch housing, and the tongue extends from the front of the switch housing to protect the switch body from travel.

[0011] Furthermore, the travel switch also includes an L-shaped baffle, the front end of the L-shaped baffle is fixed to the rear end of the switch housing, and the side is fixed to the side wall of the U-shaped plate. The side wall of the U-shaped plate is provided with a notch corresponding to the L-shaped baffle, which is used for routing and protecting internal circuits using the L-shaped baffle and the U-shaped plate.

[0012] Furthermore, the travel switch also includes an adjusting screw, which penetrates from the side wall of the switch housing and abuts against the switch body to fix the front and rear installation positions of the switch body in the switch housing and control the forward extension distance of the tongue.

[0013] Furthermore, the front end opening of the shield is flared, and the cross section is V-shaped or trapezoidal. In this structure, the side wall of the strip steel coil is arc-shaped, and when it contacts the two auxiliary wheels, the flared structure is provided to avoid the side wall from colliding and interfering with the shield at the position between the two auxiliary wheels.

[0014] Furthermore, the two auxiliary wheels are arranged symmetrically with the central axis of the cylinder as the center line, and the center of the strip steel coil is located on the central axis of the cylinder. In this structure, when the cylinder pushes the two auxiliary wheels forward, the two auxiliary wheels can contact the side wall of the strip steel coil at the same time, thereby preventing the identification device from being offset to the left and right.

[0015] Furthermore, there is an angle β between the setting direction a of the travel switch and the setting direction b of the cylinder, 5°≤β≤10°. In this structure, during identification, the tail of the strip coil hits the tongue for a long time, which is easy to cause damage to it. Setting the angle β can reduce the rotation angle of the tongue, thereby extending the service life of the travel switch.

[0016] Beneficial effect: Compared with the prior art, the advantages of the present invention are: the tail position of the strip steel coil can be accurately identified through the travel switch, so as to avoid the tail position when executing the subsequent coding and bundling processes, prevent coding and bundling failures, and provide a positioning basis for the automated single-bundle packaging of the strip steel.

[0022] The cylinder 2 is fixed on the base 1, the front end of the shield 3 is open, and the rear bottom is fixedly connected to the movable end of the cylinder 2. There are two auxiliary wheels 4, which are fixedly arranged on the left and right sides of the shield 3, respectively. The front side of the auxiliary wheel 4 is exposed from the front end opening of the shield 3. The travel switch 5 includes a switch body 5a, a rotating shaft 5b, a tongue 5c, a switch housing 5d, an L-shaped baffle 5e, and an adjusting screw 5f. The switch body 5a is located outside the shield 3 and fixed to the side wall of the shield 3. The tongue 5c is connected to the switch body 5a through the rotating shaft 5b. The auxiliary wheel 4 and the rotating shaft 5b are parallel to the axial direction of the strip steel coil. The front end of the tongue 5c exceeds the front end connection line of the two auxiliary wheels 4, so that when the two auxiliary wheels 4 abut against the strip steel coil 100, the tongue 5c is squeezed by the strip steel coil 100 and rotates.

[0023] In this embodiment, in order to make the extension and retraction of the cylinder 2 more stable, a supporting mechanism 6 is provided, which specifically includes a U-shaped plate 6a, a slide rail 6b, a slider 6c, and a bottom plate 6d. The opening of the U-shaped plate 6a faces upward, the front end is fixedly connected to the rear bottom of the protective cover 3, and the movable end of the cylinder 2 is fixed inside. The U-shaped plate 6a wraps and protects the movable end of the cylinder 2; the bottom plate 6d is fixed on the base 1 and is located below the U-shaped plate 6a; the slide rail 6b is fixed on the upper surface of the bottom plate 6d, and the extension direction of the slide rail 6b is the same as the extension and retraction direction of the movable end of the cylinder 2; the slider 6c slides on the slide rail 6b and is fixed to the lower bottom surface of the U-shaped plate 6a.

[0024] In this embodiment, in order to protect the switch body, a switch housing 5d is provided. The switch housing 5d is through-through from front to back, and its outer wall is connected to the outer wall of the shield 3. The switch body 5a and the rotating shaft 5b are arranged inside the switch housing 5d, and the tongue 5c extends from the front of the switch housing 5d.

[0025] In this embodiment, in order to facilitate wiring and protect the circuit, an L-shaped baffle 5e is provided. The front end of the L-shaped baffle 5e is fixed to the rear end of the switch housing 5d, and the side is fixed to the side wall of the U-shaped plate 6a. A notch corresponding to the L-shaped baffle 5e is opened on the side wall of the U-shaped plate 6a.

[0026] In this embodiment, in order to facilitate the adjustment and control of the forward extension distance of the tongue, a joint screw 5f is provided. The adjustment screw 5f penetrates from the side wall of the switch housing 5d and abuts against the switch body 5a.

[0027] In this embodiment, the connection structure between the cylinder 2 and the U-shaped plate 6a is as follows: a cylinder connection head 7 is provided inside the U-shaped plate 6a, and the movable end of the cylinder 2 is connected to the cylinder connection head 6e via a floating joint 8.

[0028] In this embodiment, since the side wall of the strip steel coil 100 is arc-shaped, when it contacts the two auxiliary wheels, in order to avoid the side wall from colliding and interfering with the shield at the position between the two auxiliary wheels, the front end opening of the shield 3 is set to be flared with a V-shaped or trapezoidal cross-section.

[0029] In this embodiment, in order to prevent the auxiliary wheels from deflecting when contacting the side wall of the strip steel coil 100 , the two auxiliary wheels 4 are arranged symmetrically with the central axis of the cylinder 2 as the center line, and the center of the strip steel coil is located on the central axis of the cylinder 2 .

[0030] In this embodiment, in order to reduce the rotation angle of the tongue and thus extend the service life of the travel switch, an angle β is set between the setting direction a of the travel switch 5 and the setting direction b of the cylinder 2, and 5°≤β≤10°.

[0031] When the identification device of this embodiment is used, the strip steel coil 100 rotates clockwise along its winding direction. When the position of its tail 101 needs to be identified, the cylinder pushes the shield close to the strip steel coil 100 under the support of the support mechanism, so that the tongue and the two auxiliary wheels are successively pressed against its side wall, and the tongue is squeezed and rotated to a certain angle. When identifying the tail 101, the position of the tail 101 of the strip steel coil is first rotated to a position where it rotates relative to the two auxiliary wheels. At this time, the two auxiliary wheels press the tail 101 tightly, and when the tail 101 turns away from the auxiliary wheels, it hits the tongue that is in back contact with it under the action of rebound, so that the position of the tail 101 of the strip steel coil is accurately identified through the force rotation of the tongue. After identifying the tail 101, the strip steel coil can be controlled to stop rotating to keep the tails 101 of all the strip steel coils in the same position, so that when executing the subsequent coding and bundling process, the tail 101 position is avoided to prevent coding and bundling failure. After the identification is completed, the cylinder is used to retract the identification device to prevent it from affecting the transportation of the strip steel coil.
