Description

Technical Field

[0001] The present invention relates to an automatic winding device, belonging to the field of automatic winding devices. Background Art

[0002] The winding mechanism of the existing winding device adopts a simple double-roller drive with the same diameter and generally arranged in parallel, or a three-roller drive with the axes arranged in a simple triangle. The roller wheels of the double-roller drive are placed horizontally or vertically; for the three-roller drive, two rollers are horizontal, and the third roller is placed above the middle of the two horizontal rollers to form an isosceles or equilateral triangle. The main disadvantages of the above winding mechanism are as follows: when two roller shafts are placed horizontally and the axes of the three roller shafts are arranged in an equilateral or isosceles triangle, the material to be wound needs to be fed from the middle of the two roller wheels or the surface of the roller wheels, and automatic winding cannot be achieved. Only semi-automatic or pure manual winding methods with manual labor and equipment can be used, increasing labor costs.

[0003] The existing winding device can only adopt semi-automatic or pure manual winding methods with manual labor and equipment, and the packaging efficiency of single parts is low. It is necessary to pre-cut the materials to be wound into a certain size, and then adopt semi-automatic or pure manual winding methods with manual labor and equipment. After packaging, the outer shape specifications (length and diameter) of the parts are different, with various shapes and poor uniformity; the semi-automatic or pure manual winding methods with manual labor and equipment increase the labor intensity for the final packaging of the parts into containers (transfer boxes or cartons), extend the packaging time, reduce the efficiency, and adopt manual feeding, placing packaging films, etc. And it is necessary to manually grasp the tubular materials, manually pre-wind them, and then put the semi-finished products into the winding mechanism for winding or pure manual winding; the wound products need to be manually wrapped with winding films on the outside; the product identification labels are manually placed on the outer surface of the products and adhered to the product surface with winding films, thin films, tapes or self-adhesive labels.

[0037] The above automatic winding device has the following advantages: The wound material realizes autonomous cutting and automatic feeding on the production line without manual handling; the automatic upper paper tube is realized through the automatic upper tubular material conveying device 40 without manual pre-winding; through the structural design of the multi-axis linkage winding mechanism 30, the wound material can realize better automatic winding, automatically feed packaging paper or packaging film, and automatically cut the packaging paper or packaging film according to the product specifications; the consumption of packaging materials is controllable; the labels are automatically placed and automatically pasted after packaging, with unified positions and neat placement; the packaged finished products are automatically unloaded and sent out of the production line; there is no need for manual blanking, saving labor costs; the entire production line only requires one person to operate, improving production efficiency and reducing manufacturing costs; through structural design, it has stable performance and high precision.

[0038] Working and using process of the roll-up device in this case:

[0039] The conveying mechanism 20 first operates to convey the sheet materials to be packaged (such as carpets, fabrics or films) placed on the conveying chain or conveying belt 24 in the direction of the multi-axis linkage roll-up mechanism 30;

[0040] An opto-electronic induction switch is installed in the middle of the conveying chain or conveying belt 24. When the material passes through this opto-electronic induction switch, two actions occur: one is that the upper tubular material driving device 44 is powered on, driving the upper tubular material chain to move upward from bottom to top. During the movement of the upper tubular material chain, the gripping tool 45 on the upper tubular material chain grabs the tubular material 410 stored on the upper tubular material bed body 42 and runs upward with the tubular material 410. After the tubular material 410 runs to the top of the bed body, under the action of the upper tubular material chain or the upper tubular material belt 462, it flips over the top and reaches the temporary storage position of the tubular material 410 at the discharging push rod mechanism 41 on the other side; the other is that the multi-axis linkage roll-up mechanism 30 runs upward around the axis of the first main transmission shaft 31 under the drive of the first driving device 35. Until the axes of the first main transmission shaft 31 and the first driven shaft 32 are in the horizontal position, the upper tubular material driving device 44 on the automatic upper tubular material conveying device 40 is powered on, and the upper tubular material transmission mechanism 46 runs in the reverse direction, and the tubular material 410 falls freely into the middle position between the first main transmission shaft 31 and the first driven shaft 32 of the multi-axis linkage roll-up mechanism 30.

[0041] After the tubular material 410 is placed well, the multi-axis linkage roll-up mechanism 30 continues to move upward. At the same time, the second driving device 363 of the single-axis movement pressing and adjusting mechanism 36, that is, the electric cylinder retracts, pulling the support frame swing arm to swing downward. The single-axis movement pressing and adjusting mechanism 36 just covers the "C" - shaped or triangular opening position 310 of the axes of the first main transmission shaft 31 and the first driven shaft 32 of the multi-axis linkage roll-up mechanism 30, making the axes of the four shafts form a circle or a quadrilateral.

[0042] The conveying mechanism 20 feeds the material. If the material to be rolled needs to be cut, a cutting mechanism 60 can also be set on the conveying mechanism 20. The cutting mechanism can be selected according to actual needs, and the material to be rolled can be cut and then fed, so that the material to be packaged enters the central part of the circle or quadrilateral formed by the four shafts of the multi-axis linkage roll-up mechanism 30 and the single-axis movement pressing and adjusting mechanism 36. The four shafts of the multi-axis linkage roll-up mechanism 30 and the single-axis movement pressing and adjusting mechanism 36 rotate simultaneously, and the transmission shafts of the four shafts of the multi-axis linkage roll-up mechanism 30 and the single-axis movement pressing and adjusting mechanism 36 rotate in the same direction at the same time ("counterclockwise or clockwise rotation") to drive the material to be rolled to rotate in the "clockwise or counterclockwise" direction to achieve automatic rolling.

[0043] When the diameter of the material to be wound gradually increases, the shafts of the multi-axis linkage winding mechanism 30 contract inward through the first connecting plate 34, causing the axis lines of the first driven shaft 32 and the first main drive shaft 31 to move from vertical to horizontal; at the same time, the shaft of the single-axis movement pressing and adjusting mechanism 36 is pushed outwards, driving the second main drive shaft 361 of the single-axis movement pressing and adjusting mechanism 36 to move in the vertical direction around the movement axis of the support frame.

[0044] When the end of the material to be wound reaches the position of the winding photoelectric induction switch, the cylinder of the automatic film winding mechanism 70 for film, paper or winding film of the multi-axis linkage winding mechanism 30 presses down, and the film winding driven shaft contacts the conveying chain or conveyor belt 24, and the packaging film is pressed tightly and moves together towards the multi-axis linkage winding mechanism 30 under the drive of the conveying drive device; when the packaging film wraps around the material to be wound for two circles, the longitudinal electric cylinder on the label automatic feeding mechanism 90 of the multi-axis linkage winding mechanism 30 extends downwards, and the pneumatic suction cup 94 adsorbs the labels pre-stored in the paper tray and then the longitudinal electric cylinder retracts. The transverse transmission slide 95 on the label automatic feeding mechanism 90 of the multi-axis linkage winding mechanism 30 moves from the outside towards the center of the device. When the position of the longitudinal electric cylinder is conveyed to the specified position, the longitudinal electric cylinder extends and places the label or paper on the surface of the packaging film. Then the longitudinal electric cylinder retracts, and the slide moves outwards and returns to its original position, preparing for the second cycle of work.

[0045] After the label placement is completed, the driving shafts of the multi-axis linkage winding mechanism 30 and the single-axis movement pressing and adjusting mechanism 36 continue to rotate. The first driven shaft 32 of the multi-axis linkage winding mechanism 30 moves horizontally downwards around the center of the first main drive shaft 31; the second main drive shaft 361 of the single-axis movement pressing and adjusting mechanism 36 moves in the vertical direction around the support axis; making the winding diameter of the material to be wound larger and larger;

[0046] After the label enters the material to be wound for two circles, the solenoid valve of the automatic cutting mechanism for film, paper or winding film of the equipment is energized, and the cylinder drives the cutting tool to move downwards to cut off the packaging film or packaging paper; the first driven shaft 32 of the multi-axis linkage winding mechanism 30 moves horizontally downwards around the center of the first main drive shaft 31; the driving shaft of the single-axis movement pressing and adjusting mechanism 36 moves in the vertical direction around the support axis; until the winding is completed;

[0047] After the winding is completed, the first driven shaft 32 of the multi-axis linkage winding mechanism 30 moves horizontally downwards around the center of the first main drive shaft 31, making the axis of the first driven shaft 32 lower than the axis of the first main drive shaft 31, and the wound material to be wound is automatically discharged. It falls freely onto the blanking transmission mechanism 50.

[0048] After the finished product falls onto the blanking and conveying mechanism 50, the blanking and conveying mechanism 50 starts to work and sends the packaged parts out of the production line.

[0049] All of the above drive devices are controlled by the PLC control device 100. The PLC control device 100 obtains the signals of the conveying photoelectric induction switch and the winding photoelectric induction switch, and thus controls the working time and duration of each mechanism according to the position of the material to be wound. As a result, the entire above system realizes automatic control. It can not only achieve automatic winding, but also has functions such as automatic labeling, tubular materials 410, packaging films, etc. The whole process is controlled by the PLC control device 100, making the whole consistent, the control accurate, and the product quality stable. It does not require manual labor, saves manpower, has high efficiency, and reduces material waste.
