[0002] During the processing of color-coated steel plates, it is necessary to move the color-coated steel plates, and sometimes it is also necessary to longitudinally cut the color-coated steel plates. In the process of moving the existing color-coated plates, double-strip positioning transmission lines are often used. If single-strip transmission is required during the transmission process, the transmission line needs to be replaced; Moreover, the existing double-strip positioning transmission lines have the split guide posts arranged on the transmission line fixed and will not swing and correct according to the state of the plate, so the diagonal of the product will not meet the standard during the subsequent longitudinal cutting of the plate; Not only that, the split part of the two strips of the existing double-strip positioning transmission line is in a flat section. When in the flat section, the transmitted plate is not affected by external forces. Therefore, it is easy for the displacement of the two strips of plates to deviate after separation and it is not easy to enter the rack for further transmission. Summary of the Invention

Detailed implementation manner

[0018] The following further elaborates on the detailed implementation manner of the present invention in conjunction with the attached drawings.

[0019] Referring to the attached Figures 1-10 specification, an intelligent positioning and guiding device includes a frame 1 and a feeding arc guide plate structure. The feeding arc guide plate structure is arranged on one side of the frame 1 close to the incoming material direction. The sheet material first contacts the feeding arc guide plate structure, and the sheet material is conveyed into the frame 1 through the feeding arc guide plate structure.

[0020] The feeding arc guide plate structure includes an arc plate 14, a second guiding roller, and a connecting plate 15. The arc plate 14 is in the shape of a quarter circle. The plane of the arc plate 14 is fixedly connected to the frame 1, and the arc surface of the arc plate 14 is used to carry a plurality of second guiding rollers. Under the action of the arc surface, the transmission part can be arched and is not easily deformed during movement; Both ends of the second guiding roller are placed on the arc surface of the arc plate 14. The sheet material of the previous process is guided to the frame 1 through the second guiding roller and transferred to the next process through the first guiding roller arranged on the frame 1; There are multiple second guiding rollers. In order to enable the second guiding rollers to better contact the arc surface of the arc plate 14, two adjacent second guiding rollers are connected by a connecting plate 15. Under the action of the connecting plate 15, a corresponding angle identical to the radian of the arc plate 14 can be formed between two adjacent second guiding rollers.

[0021] The feeding arc guide plate structure further includes a plate dividing guide disc structure. The plate dividing guide disc structure can be one or more. The plate dividing guide disc structure is arranged between two adjacent second guiding rollers and is slidably connected to the connecting plate 15. When the plate dividing guide disc structure moves upward to the limit position, it will conduct plate dividing and guiding for double-strip sheet materials. When the plate dividing guide disc structure moves downward to the limit position, its outer edge surface will be lower than between the multiple second guiding rollers and will not interfere with single-piece whole plates.

[0022] The board splitting guide disk structure includes a guide disk shaft 16, a guide disk wheel 17, and a lifting component 18. The guide disk wheel 17 is arranged on the guide disk shaft 16 for guiding double strip materials. The lifting component 18 is fixedly connected to the connecting plate 15 and its output shaft is rotatably connected to the guide disk shaft 16. The lifting component 18 can adopt a series of structures that can generate linear displacement, such as a lifting cylinder, an electric push rod, or a rack and pinion, etc. The guide disk shaft 16 and the guide disk wheel 17 thereon are moved through the structure that can generate linear displacement; The outer edge diameter of the guide disk wheel 17 is larger than the diameter of the guide disk shaft 16. When the lifting component 18 drives the guide disk shaft 16 to move upward to the limit position, the guide disk wheel 17 is higher than the outer edge of the second material guiding roller to separate and guide the double strips of plates.

[0023] The connecting plate 15 is provided with a limiting groove 19 for accommodating the guide disk shaft 16. The guide disk shaft 16 is limited and guided through the limiting groove 19. The guide disk shaft 16 is inserted into the limiting groove 19 and slides relative to the limiting groove 19.

[0024] The frame 1 is provided with a first material guiding roller, a material plate guiding part, and a longitudinal cutting material guiding device. Among them, there are multiple first material guiding rollers evenly distributed along the moving direction of the material plate. Through the setting of the first material guiding rollers, the material plate located in the frame 1 can be assisted to move; The material disk guiding part is arranged between two adjacent first material guiding rollers for limiting the edge of the material disk. The material disk guiding part includes a moving plate 9, a guide wheel 10, and a driving structure. There are two moving plates 9 evenly distributed on both sides of the frame body 3. The guide wheel 10 is arranged on the moving plate 9 and is rotatably connected to the moving plate 9. The upper end of the guide wheel 10 is higher than the first material guiding roller for contacting the edge of the material plate. The driving structure is threadedly connected to the moving plate 9 for driving the moving plate 9 to move along the axial direction; The driving structure can drive the two moving plates 9 and the guide wheels 10 thereon to move relatively or away from each other. By the relative or opposite movement of the two moving plates 9, the guide wheel 10 contacts the edge of the plate material, and the edge of the plate material is limited by the guide wheel 10.

[0025] The driving structure includes a rotating shaft 11, a rotating ring 12 and a driving component 13. The rotating shaft 11 is sleeved inside the rotating ring 12 and is threadedly connected to one of the moving plates 9. The rotating ring 12 is threadedly connected to the other moving plate 9. There are two driving components 13 which respectively drive the rotating shaft 11 or the rotating ring 12 to rotate. The driving component 13 can be arranged by matching a servo motor with a reducer. One of the driving components 13 is used to drive the rotating shaft 11 to rotate. Since the rotating shaft 11 is threadedly connected to the moving plate 9, it can drive the moving plate 9 to move axially along the rotating shaft 11. The other driving component 13 is used to drive the rotating ring 12 to rotate. Since the rotating shaft 11 is sleeved between the rotating shaft 11 and the rotating ring 12, the rotating shaft 11 will not interfere with the rotating ring 12 when the rotating shaft 11 rotates, and the rotating directions between the rotating shaft 11 and the rotating ring 12 can be opposite, so as to realize that the two moving plates 9 can move relatively or away from each other to adapt to the incoming materials of plates with different widths.

[0026] A positioning grating ruler is provided on the arc-shaped plate 14. The positioning grating ruler is connected to the driving component 13 and the lifting component 18 through a control module to form a closed-loop control. The width of the sheet material in the incoming direction of the sheet material is identified by the positioning grating ruler. After identification, the identification information is converted into an electrical signal, and the control module controls the servo motor to rotate at an appropriate angle, so as to realize the close fitting of the guide wheel 10 to the edge of the sheet material. The positioning grating ruler is a prior art and will not be elaborated here. At the same time, the setting of the positioning grating ruler is a conventional setting in the art, so it is not shown in the accompanying drawings of the specification.

[0027] The control module generally uses a PCL control board, which can convert digital signals into electrical signals and realize control actions.

[0028] The longitudinal cutting and guiding device is slidably connected to the frame 1 through the auxiliary cylinder 2 and is arranged at the middle position of the first guiding roller for guiding double strip materials. The longitudinal cutting and guiding device includes a frame body 3, a shaft sleeve 4 and a contact shaft 5. There are multiple shaft sleeves 4, and two adjacent shaft sleeves 4 are staggered. The shaft sleeve 4 is installed on the frame body 3 and is rotatably connected to the frame body 3. The contact shaft 5 is eccentrically arranged inside the shaft sleeve 4 and is installed on the frame body 3 through bolts. The contact shaft 5 contacts one end of the sheet material and is pressed by the edge of the sheet material; Since the shaft sleeve 4 is rotatably connected to the frame body 3, and at the same time two adjacent shaft sleeves 4 are staggered and the contact shaft 5 is eccentrically inserted into the shaft sleeve 4, when the contact shaft 5 contacts the edge of the sheet material, the shaft sleeve 4 will be driven to rotate relative to the frame body 3 by the extrusion of the edge of the sheet material. Also, due to the eccentric fit between the contact shaft 5 and the shaft sleeve 4, the shaft sleeve 4 can automatically rotate to a state where multiple contact shafts 5 are in a straight line, and in the eccentric fit state, the contact shaft 5 can have a certain swing amplitude, so as to provide a certain left and right offset for the transportation of the sheet material, which can make the sheet material move better.

[0029] The inner edge surface of the bushing 4 is provided with an oil guide groove 6 in a thread shape. An auxiliary shaft 7 is arranged in the contact shaft 5 and is rotatably connected to the contact shaft 5 through a bearing. The auxiliary shaft 7 can be higher than the first material guiding roller and contact the edge of the sheet material. The oil guide groove 6 is used to lubricate the contact shaft 5, enabling the contact shaft 5 to move better. Under the action of the bearing, the auxiliary shaft 7 can rotate relative to the contact shaft 5, making it more convenient for the movement of the sheet material. Under the action of the auxiliary cylinder 2, the up and down movement of the auxiliary shaft 7 can be realized. When there are two strips of incoming sheet materials, the auxiliary cylinder 2 starts to drive the auxiliary shaft 7 to move upward to above the first material guiding roller and contact the inner edge of the two strips of incoming sheet materials.

[0030] A plurality of auxiliary holes 8 corresponding to the contact shaft 5 one by one are formed on the frame body 3. The bolts arranged on the contact shaft 5 are located in the auxiliary holes 8 and are eccentrically matched with the auxiliary holes 8. The bolts are inserted into the auxiliary holes 8 and can rotate relative to the auxiliary holes 8. Here, the bolts can only limit the contact shaft 5 in the up and down direction and cannot limit the contact shaft 5 in the circumferential direction of the shaft. Therefore, when the auxiliary cylinder 2 moves up and down, it can drive the contact shaft 5 to move up and down.

[0031] When the present invention is in use, the material plate moves from one side of the feeding arc guide plate structure to one side of the frame 1. At the same time, a driving source for driving the movement of the incoming sheet material is arranged on one side of the feeding arc guide plate structure, and the incoming sheet material is driven to move through the driving source. When the incoming sheet material is a single board, at this time, the lifting assembly 18 will not drive the guide disk shaft 16 to lift or lower. Under the action of the second material guiding roller, the incoming sheet material moves along the arc surface of the arc-shaped plate 14 towards the frame 1. Under the action of the positioning grating ruler, the edge of the incoming sheet material is positioned. After receiving the positioning information of the positioning grating ruler, the control module drives the driving assembly 13 to start. Under the action of the corresponding electrical signal, the driving assembly 13 rotates to a suitable angle, and the rotation of the rotating shaft 11 and the rotating ring 12 is realized through the rotation of the driving assembly 13. When the rotating ring 12 and the rotating shaft 11 rotate, the moving plate 9 threadedly connected to the rotating ring 12 or the rotating shaft 11 can achieve the purpose of moving axially along the rotating shaft 11. Through the movement of the moving plate 9, the outer edge surface of the guide wheel 10 corresponds to the width of the incoming sheet material, and the edge of the incoming sheet material is limited by the guide wheel 10. At the same time, under the action of the first material guiding roller, the incoming sheet material is moved to the next working station. When the incoming sheet material is two strips, the grating positioning ruler identifies the incoming sheet material and drives the lifting assembly 18 to start, so that the guide disk shaft 16 moves towards the second material guiding roller. The outer edge surface of the guide disk wheel 17 is higher than the second material guiding roller to initially separate the incoming sheet material in a double-board separated state. While the lifting assembly 18 is activated, the auxiliary cylinder 2 is activated to move the auxiliary shaft 7 above the outer edge surface of the first material guiding roller. When the sheet material comes in and moves through the second material guiding roller to the frame 1, the inner edges of the double-strip sheet material come into contact with the auxiliary shaft 7 and press the contact shaft 5 through the auxiliary shaft 7. When the contact shaft 5 is pressed, due to the eccentric fit between the contact shaft 5 and the bushing 4, the contact shaft 5 will press the bushing 4 to rotate, prompting a straight line formed by multiple auxiliary shafts 7 to fit the edge of the sheet material; Moreover, with the bearing arrangement between the auxiliary shaft 7 and the contact shaft 5, the inner edges of the double-strip sheet material can drive the auxiliary shaft 7 to rotate, thus also promoting the better movement of the sheet material.

[0032] The present invention adopts the rotatably arranged bushing 4 and the contact shaft 5 arranged eccentrically with the bushing 4 inside the bushing 4, which can enable the edge of the sheet material to be properly limited during the movement of the double plates. At the same time, due to the eccentric setting of the contact shaft 5 and the bushing 4 and the rotational connection between the bushing 4 and the frame body 3, the contact shaft 5 can rotate along the center of the bushing 4, realizing the left and right offset amount between the contact shaft 5 and the middle position of the first material guiding roller, and enabling better movement of the sheet material.

[0033] The present invention adopts the auxiliary cylinder 2, the auxiliary hole 8 opened on the frame body 3, and the bolt arranged on the contact shaft 5 and located in the auxiliary hole 8, which can realize the up and down movement of the auxiliary shaft 7 and will not interfere with the rotation of the auxiliary shaft 7. Under the action of the auxiliary cylinder 2, it can be adjusted according to the state of double plates or single plates.

[0034] The present invention adopts the driving assembly 13, the rotating shaft 11, the rotating ring 12, the moving plate 9, and the guide wheel 10, which can enable the guide wheels 10 located on both sides of the sheet material to automatically move relatively or away from each other. Moreover, the sleeving between the rotating shaft 11 and the rotating ring 12 can enable the driving assembly 13 to drive the rotating shaft 11 or the rotating ring 12 separately, and the rotating directions can be the same or opposite during the rotation process. Under the action of the grating positioning ruler, the control module drives the moving plate 9 and the guide wheel 10 thereon to contact the edge of the sheet material.
