Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of waterproof roll production equipment, and particularly relates to a waterproof roll production system based on thickness over-standard detection and tracking marking. BACKGROUND

[0002] There are various types of waterproof rolls, which are flexible building waterproof materials and are used to be laid on the water-involved surfaces of walls and roofs of buildings to form water-avoiding barriers. Modified asphalt waterproof roll is one of the commonly used types. The modified asphalt waterproof roll is usually made of polyester fiber non-woven fabric, glass fiber felt as a base, modified petroleum asphalt as an impregnated covering layer on the surface of the base, and plastic film as a non-stick separation layer. The modified asphalt waterproof roll has certain properties such as high temperature resistance, fatigue resistance, ductility, elasticity and tear resistance. When a factory produces a modified asphalt waterproof roll, the base cloth needs to be continuously fed into the production line so that the base cloth can be processed through oil immersion, asphalt immersion, film pressing, cooling, length cutting according to requirements, and roll packaging. Since the base cloth is purchased in rolls before entering the production line, and each roll is usually tens of meters long, in order to ensure the continuity of production, the tail end of the previous roll of base cloth needs to be overlapped with the head end of another roll of base cloth and connected by an adhesive. The connection needs to have strong tensile resistance to prevent separation under tension during production. However, this makes the base cloth at the connection have a certain width of thickness over-standard area, which can easily cause uneven distribution of the immersed material during oil immersion and asphalt immersion, and can easily cause gaps between the non-stick separation layer and the impregnated covering layer during film coating, thereby affecting the performance of the waterproof roll within a certain range. Therefore, the area of the base cloth with thickness over-standard at the connection is usually cut off when the waterproof roll is cut to the required length.

[0003] In the prior art, the thickness over-standard area of the base cloth after film coating has no obvious features in appearance, and manual thickness measurement is needed to carefully identify and find the thickness over-standard area before cutting. This is extremely inefficient. Some manufacturers want to solve this problem by improving the equipment. A real-time thickness measuring device is used to measure the thickness over-standard area of the base cloth during production and track or mark the area, so that the visual recognition system can identify the thickness over-standard area and automatically cut it off during cutting. However, since the base cloth still needs to go through processes such as oil immersion, asphalt immersion and film coating during thickness measurement, the mark is easily covered or invalidated, which makes it difficult for the visual recognition system to identify, and makes it difficult to implement the above-mentioned production process improvement method. The problem of low production efficiency, high product waste rate caused by low identification efficiency of the thickness over-standard area and low cutting efficiency and poor cutting precision is still difficult to solve.

[0024] The drawings will be described below in combination with the drawings of the embodiments Figure 1 to the drawings Figure 4 The present application will be further described in detail in combination with specific embodiments.

[0025] In the present application, a waterproofing membrane production system based on thickness over-standard detection and tracking marking is disclosed. In addition to the thickness detection mechanism 60 and the marking mechanism 70 for solving the technical problems of the present case, the system also includes some necessary equipment in the prior art, such as the base fabric unwinding mechanism 10 for orienting the transport of the base fabric 11 along the running direction of the waterproofing membrane production line, the base fabric impregnation mechanism 30 for oil and bitumen impregnation on the surface of the base fabric 11, the synchronous film covering mechanism 40 for pressing the plastic film 43 (hereinafter referred to as film 43) onto the surface of the base fabric 11 to form an anti-sticking isolation layer, etc. Among them, the base fabric unwinding mechanism 10 includes multiple sets of transmission cooperating conveying rollers, which fully unwinds the coiled base fabric 11 on the production line and transports it to the end of the production line. A base fabric connecting mechanism 20 is also provided at the entrance of the production line, which connects the head and tail of two base fabrics 11 successively fed into the production line to form a thickened area for anti-pulling. This area is the thickness over-standard area of the base fabric 11 or the combined waterproofing membrane. Since this area is formed by the head and tail of the base fabric 11 through hot pressing, sewing or adhesive connection, etc., it is usually rectangular, with a length equal to the original width of the base fabric 11 and a width equal to half the total width of the overlapping part of the base fabric 11. Along the running direction of the production line, a base fabric pre-unwinding device 80 is provided downstream of the base fabric connecting mechanism 20. The device uses multiple sets of conveying rollers arranged staggered in the height direction to transport the base fabric 11 in a certain height range through multiple turns in a limited production space, thereby achieving the effect of quickly unwinding the base fabric 11 from the coiled state in advance, so as to facilitate the connection of the tail end of the base fabric 11 with the head end of another base fabric 11. The base fabric impregnation mechanism 30 is provided downstream of the base fabric pre-unwinding device 80. The mechanism is used to impregnate the base fabric 11 with modified bitumen during the movement and transportation process, so as to form an impregnated cover layer on the surface of the base fabric 11. The synchronous film covering mechanism 40 is provided downstream of the base fabric impregnation mechanism 30. The synchronous film covering mechanism 40 includes several film conveying rollers 41 and a film pressing roller 42 in contact with the surface of the base fabric 11. The film conveying rollers 41 are used to unwind the coiled film 43 and transport it synchronously to the position where it meets the base fabric 11 at the same speed as the base fabric 11. The moving film 43 is attached to the impregnated cover layer on the surface of the base fabric 11 through the film pressing roller 42 to form an anti-sticking isolation layer.

[0026] In order to attach the film 43 to both upper and lower surfaces of the base fabric 11, the above-mentioned synchronous film coating mechanism 40 is usually symmetrically arranged on both upper and lower sides of the base fabric 11. A cooling mechanism (which is a prior art and is irrelevant to the focus and structure distribution of the present case, and thus not shown in the figure) for cooling the asphalt is arranged downstream of the synchronous film coating mechanism 40, and a cutting mechanism 50 is arranged at the end of the production line, for cutting the waterproofing membrane according to the required length of the product or cutting off the area of the waterproofing membrane with excessive thickness.

[0027] Specifically, the thickness detection mechanism 60 is arranged upstream of the tire base fabric impregnation mechanism 30, and the purpose of arranging it here is to accurately measure the thickness of the tire base fabric 11 itself. If it is arranged downstream of the tire base fabric impregnation mechanism 30, the accuracy of the thickness detection mechanism 60 in measuring the thickness of the tire base fabric 11 can be affected by the asphalt coating on the surface of the tire base fabric 11. The thickness detection mechanism 60 includes a support frame 61 and a thickness detector 62. The support frame 61 is used to fix the thickness detector 62 to the production line, so that the thickness detector 62 can detect the thickness of the tire base fabric 11 at a fixed point. The thickness detector 62 includes a laser thickness sensor and a microcomputer. The laser thickness sensor outputs the thickness of the horizontally moving tire base fabric 11 in real time, and the microcomputer compares the output thickness signal value with the standard value in real time to determine whether the area with excessive thickness on the tire base fabric 11 has reached the position of the thickness detector 62. When the answer is "yes", a position signal of the area with excessive thickness is sent out at the same time. The marking mechanism 70 is arranged between the tire base fabric impregnation mechanism 30 and the synchronous film pressing mechanism, and is adjacent to one side of the film pressing roller 42 of the synchronous film pressing mechanism. The marking mechanism 70 includes a controller and a mounting frame 71. The mounting frame 71 is arranged on the upper surface or lower surface of the tire base fabric 11 and is located on one side of the film pressing roller 42. In this application, it is preferably arranged on the lower surface of the tire base fabric 11. Since the marking mechanism 70 is a device for automatically pasting a marking sticker 724 on the surface edge of the film 43, and since the marking sticker 724 has at least part of it protruding from the side of the waterproof coiled material to form a clear mark, the effect is basically the same whether it is for the upper surface or the lower surface of the tire base fabric 11. Therefore, the marking mechanism 70 can only perform the labeling work on the film 43 on one side. The mounting frame 71 is provided with a marking supply assembly 72 and a labeling assembly 73. The controller is a PLC controller with a delay control function. The PLC controller is electrically connected with the labeling assembly 73 and the thickness detector 62. The marking supply assembly 72 is used to transport the marking stickers 724, which are respectively divided into a pasting area and a marking area on the same side, one by one to a first position. The first position is a position where the labeling assembly 73 can easily obtain the marking stickers 724. When the PLC controller receives the position information of the area with excessive thickness, it can control the labeling assembly 73 to accurately obtain the marking stickers 724 within a certain time range according to the time when the area with excessive thickness reaches the position of the film pressing roller 42, and paste the marking stickers 724 on the edge of the area on the surface of the film 43 that can be attached to the position of the area with excessive thickness, so that the marking area of the marking stickers 724 can clearly show the position of the mark, so that when the film 43 and the tire base fabric 11 are integrated, the connection of the tire base fabric 11 can be accurately found at the cutting mechanism 50 by manual or visual recognition device based on the marking area.

[0028] When the waterproof roll production system based on the above thickness over-standard detection and tracking marking is used, since the transportation process of the film 43 by the synchronous film covering mechanism 40 is synchronous with the transportation process of the base fabric 11, when the position of the thickness over-standard area is detected by the thickness detector 62, the moving speed, moving distance and meeting time of the thickness over-standard area from the thickness detection position to the position of the film pressing roller 42 can be determined. Based on the characteristics, the above PLC controller only needs to control the marking assembly 73 to stick the marking sticker 724 on the film 43 according to the above meeting time node. When the film 43 meets and adheres to the base fabric 11, the marking sticker 724 is clamped between the film 43 and the base fabric 11. By pre-setting the structure of the metal sheet, magnetic patch or fluorescent coating in the marking area of the marking sticker 724, the marking sticker 724 can be inducted by the automatic induction equipment of metal or magnetism and send alarm information or cutting instruction, or the visual recognition equipment which can sensitively recognize the fluorescent coating and send alarm information or cutting instruction, or other existing technologies with the same marking recognition principle, to assist the manual identification of the thickness over-standard area or the automatic cutting of the cutting mechanism 50, so as to solve the problems of low cutting efficiency, poor cutting precision, low production efficiency and high product waste rate caused by the low identification efficiency of the thickness over-standard part.

[0029] The waterproof roll production system based on the above thickness over-standard detection and tracking marking has at least the following beneficial effects:

[0030] I. The thickness detection mechanism 60 can accurately find the position of the thickness over-standard area of the base fabric 11, and accurately control the marking mechanism 70 to stick the marking sticker 724 on the edge of the area where the surface of the film 43 meets the thickness over-standard area of the base fabric 11, so that the thickness over-standard area of the waterproof roll is marked in advance. The marking sticker 724 can magnify the identified characteristics of the thickness over-standard area, improve the identification efficiency of the thickness over-standard area, and help to improve the cutting efficiency and cutting precision.

[0031] II. The above marking mechanism 70 marks on the surface of the film 43, which solves the problem that the marking is covered or damaged after the base fabric 11 is marked in some existing technologies due to the oil or pitch immersion process, reduces the identification difficulty of the marking, improves the identification success rate of the thickness over-standard area, and helps the automation production and cutting modification of the waterproof roll production line.

[0032] In addition, the application also provides some more specific embodiments to perfect the above waterproof roll production system based on the thickness over-standard detection and tracking marking.

[0033] In a preferred embodiment, the label supply assembly 72 comprises two winding rollers 721 distributed along the transport direction of the film 43 and rotatably connected to the mounting frame 71 through bearings, and a first motor 722. The winding rollers 721 have their roller surfaces wound with a paper tape 723, and the paper tape 723 has a plurality of label stickers 724 arrayed and pasted thereon. The label stickers 724 are rectangular, and one side of the label stickers 724 is evenly divided into a pasting area coated with an adhesive coating and an area for setting an identified mark such as a metal sheet, a magnetic sticker or a fluorescent coating, and the other side is an acquisition surface easily acquired by the labeling assembly 73 through adsorption, pasting or the like. The first motor 722 is disposed on the mounting frame 71 and has its drive shaft in transmission connection with any one of the two winding rollers 721. By intermittently starting and stopping the motor, the winding rollers 721 are driven to rotate intermittently, so that one of the winding rollers 721 releases the paper tape 723, and the other winding roller 721 winds the paper tape 723, thereby achieving the step-by-step unfolding and transport of the label stickers 724 on the paper tape 723 to a position easily acquired by the labeling assembly 73, i.e., a first position. In this embodiment, the position can be the position between the two winding rollers 721. Under the action of the winding force of the winding rollers 721, the paper tape 723 is taut at the position and forms a horizontal plane in the vertical direction, so that the label stickers 724 can be easily acquired by the labeling assembly 73.

[0034] Further, in order to enable the labeling assembly 73 to obtain the label sticker 724 from the paper tape 723 of the above-mentioned label supply assembly 72 and paste it on the film 43, the above-mentioned labeling assembly 73 comprises a second motor 731, a mounting turntable 732, a label sticker suction cup 733, a negative pressure hose 734, and a vacuum pump 735, wherein the housing of the second motor 731 is fixed to the mounting frame 71 at the side facing the paper tape 723, the driving shaft of the second motor 731 is coaxially and drivingly connected with the shaft core of the mounting turntable 732, the label sticker suction cup 733 is a micro suction cup used by an industrial robot hand, the fixed end of the label sticker suction cup 733 is fixed to the disc surface of the mounting turntable 732, and the suction end of the label sticker suction cup 733 extends out of the profile of the mounting turntable 732, the vacuum pump 735 is fixed to one side of the mounting disc, the inner cavity of the label sticker suction cup 733 is communicated with the vacuum pump 735 through the negative pressure hose 734, and the above-mentioned components constitute a device for taking and pasting the label sticker 724. Through controlling the vacuum pump 735, a negative pressure adsorption area is formed at the end of the label sticker suction cup 733 extending out of the mounting turntable 732; through controlling the second motor 731 to adjust the left or right rotation of the mounting turntable 732, the negative pressure adsorption end of the label sticker suction cup 733 contacts the label sticker 724 at the first position, and the label sticker 724 is adsorbed to the label sticker suction cup 733, after that, the second motor 731 drives the mounting turntable 732 to rotate reversely, the label sticker suction cup 733 takes the label sticker 724 from the paper tape 723 and pastes the adhesive area on the back of the label sticker 724 on the film 43 opposite to the paper tape 723.

[0035] Specifically, the above-mentioned second motor 731 is electrically connected with the above-mentioned PLC controller, the PLC controller controls the second motor 731 according to the time length from the thickness detection position to the position where the film 43 meets the thickness exceeding area of the set thickness, so that the second motor 731 accurately performs the above-mentioned action according to the time length, and the label sticker suction cup 733 completes the action of taking the label sticker 724 and pasting the label sticker 724 on the film 43 at the edge of the area corresponding to the position of the thickness exceeding area of the tire base fabric 11, thereby achieving the purpose of marking the connection position of the tire base fabric 11.

[0036] In order to prevent the disc surface of the label sticker suction cup 733 from not fully contacting the label sticker 724 when contacting the paper tape 723 or the film 43 due to the stress deformation of the paper tape 723 or the film 43, thereby affecting the firmness of the label sticker suction cup 733 taking the label sticker 724, leading to the failure of taking the label sticker 724, or the label sticker 724 being pasted on the surface of the film 43 at an inclined angle or being misaligned with the preset adhesive area during the transfer process due to the movement of the disc surface of the label sticker suction cup 733, some embodiments are provided to achieve the above-mentioned purpose.

[0037] Further, the mounting disc 732 is a cam disc, i.e. the profile of the mounting disc is in the shape of a cam, and the fixed end of the label suction disc 733 is offset from the axis of the cam disc and is arranged on the disc surface of the cam disc. When the second motor 731 drives the mounting disc 732 to rotate, the cam disc can make the label suction disc 733 increase the pressure on the paper tape 723 and the film 43 when the label suction disc 733 contacts the paper tape 723 and the film 43, so that the disc surface of the label suction disc 733 is in full contact with the label 724.

[0038] In addition, the mounting frame 71 is fixed with a first limiting plate 711 on one side, and the first limiting plate 711 is located on the side of the paper tape 723 away from the label 724, and the plane of the side of the first limiting plate 711 facing the labeling assembly 73 is close to the surface of the side of the paper tape 723 away from the labeling assembly 73. When the label suction disc 733 contacts the label 724 on the paper tape 723 under the action of the right rotation of the mounting disc 732, the first limiting plate 711 can prevent the paper tape 723 from being deformed by bending to the right, and cooperate with the label suction disc 733 to fully contact the label 724, so as to ensure that the label 724 can be firmly adsorbed on the disc surface of the label suction disc 733.

[0039] Further, the mounting frame 71 is fixed with a first limiting plate 711 on one side, and the first limiting plate 711 is located on the side of the paper tape 723 away from the label 724, and the plane of the side of the first limiting plate 711 facing the labeling assembly 73 is close to the surface of the side of the paper tape 723 away from the labeling assembly 73. When the label suction disc 733 contacts the label 724 on the paper tape 723 under the action of the right rotation of the mounting disc 732, the first limiting plate 711 can prevent the paper tape 723 from being deformed by bending to the right, and cooperate with the label suction disc 733 to fully contact the label 724, so as to ensure that the label 724 can be firmly adsorbed on the disc surface of the label suction disc 733.

[0040] To further increase the adhesion of the label 724 on the surface of the film 43, the mounting frame 71 is rotatably provided with a pressing roller 713 adjacent to one side of the film 43. In the direction of the film 43, the pressing roller 713 is located downstream of the labeling assembly 73, the axial direction of the pressing roller 713 is consistent with the width direction of the film 43, and the surface of the pressing roller 713 is in contact with the area of the surface of the plastic film 43 for adhering the label 724. After the label 724 is adhered to the surface of the film 43 by the label suction cup 733, the film 43 carrying the label 724 passes through the pressing roller 713, and under the rolling and pressing action of the pressing roller 713, the label 724 is tightly adhered to the surface of the film 43, so as to prevent the label 724 from falling off during the movement of the film 43 and causing the label to fail.

[0041] Further, since the labeling mechanism 70 is arranged on the lower surface of the tire base cloth 11 to perform labeling, in order to prevent the asphalt liquid carried on the lower surface of the tire base cloth 11 from dropping onto the surface of the labeling mechanism 70 and causing labeling pollution, the mounting frame 71 is provided with a receiving groove 714 adjacent to one side of the lower surface of the tire base cloth 11. The receiving groove 714 is detachably connected with the mounting frame 71, and at least in the horizontal direction, the receiving groove 714 can cover the upper surface of the labeling mechanism 70, so that the asphalt liquid droplets falling from the surface of the tire base cloth 11 within the area above the labeling mechanism 70 can be blocked by the receiving groove 714. When the receiving groove 714 is full, the receiving groove 714 can be detached and replaced, or the asphalt in the receiving groove 714 can be transported out through a pre-set pipeline or transport groove, so as to prevent the asphalt liquid from overflowing.

[0042] In combination with the above-mentioned embodiments, the waterproof roll production system based on thickness detection and tracking labeling can automatically track and label the area of the tire base cloth 11 with excessive thickness, so as to assist the cutting mechanism 50 to accurately cut off the area, and ensure the production quality of the waterproof roll.

[0043] Obviously, the above-mentioned embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. Based on the above-mentioned description, any modifications, equivalent replacements and improvements made by those skilled in the art within the spirit and principles of the present application should be included in the protection scope of the present application.
