Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a device and method for processing coiled materials. Background Art

[0002] In industry, in order to facilitate the production, transportation, storage and subsequent automated processing of raw materials, they are curled during production to make them into coils; and when used, they need to be uncoiled to form strips with a smooth surface and uniform and stable mechanical properties, which facilitates further processing of the raw materials into semi-finished products or finished products.

[0003] In order to meet the needs of coil unwinding, various types of unwinding equipment have appeared on the market. It is found in use that although the currently used automatic unwinding equipment has high unwinding efficiency, strong safety and relatively high precision, the currently used unwinding equipment does not have the ability to adjust the mechanical properties and surface quality of the processed coils during the unwinding operation. As a result, the plates after unwinding often have serious internal stress concentration, poor mechanical properties, easy surface corrosion or uneven plate thickness, resulting in poor consistency of products processed by continuous punching and other methods and low production yield.

[0004] The prior art discloses a coil tension control device (application number: 201520211417.2), which includes a mounting frame, two first guide rollers installed at one end of the mounting frame, a second guide roller installed at the other end of the mounting frame, a tension sensor, a drive motor, a tension regulator, and a connecting belt connecting the drive motor and the tension regulator. The first guide rollers are arranged on both sides of the end where the mounting frame is located, and the second guide roller is arranged in the middle of the end. The drive motor drives the position of the tension regulator through the connecting belt according to the tension of the coil detected by the tension sensor to adjust the tension of the coil passing between the first guide roller and the second guide roller.

[0005] The prior art also discloses a fully automatic coil punching machine (application number: 201811553729.6), which includes a frame, a unwinding and tension control mechanism, a coil material incoming detection mechanism, a material strip thickness measuring mechanism, a material strip air permeability measuring mechanism, a material strip continuous punching mechanism, a material strip feeding and winding mechanism, an online detection mechanism for punching products, and a punching product conveying and collecting mechanism, wherein the unwinding and tension control mechanism is used to unwind and control the tensile tension of the material strip, the material strip thickness measuring mechanism is used to measure the thickness of the material strip, the material strip air permeability measuring mechanism is used to measure the air permeability of the material strip, the material strip continuous punching mechanism is used to continuously punch the material strip, the material strip feeding and winding mechanism is used to feed the material strip and collect the waste after punching, the punching product online detection mechanism is used to detect the punched products, and the punched product conveying and collection mechanism is used to convey and collect the punched products.

[0006] The existing solutions are generally to make the coil free of gravity, or to use vacuum adsorption or spring roller tensioning to provide tension, so that the tension state of the coil is uncontrollable or the tension cannot be controlled constantly, thereby improving its production efficiency. However, the existing methods of tensioning the raw materials all require additional power, the device structure is complex, and the reciprocating intermittent or frequent start-stop processing of the raw materials requires high precision control of the device. Summary of the invention

[0007] In view of the deficiencies in the above-mentioned technologies, the purpose of the present invention is to provide a non-powered self-balancing coil processing device.

[0012] The coiled material after passing through the traction mechanism is guided by the adjusting guide roller, and passes through the first balancing guide roller, the raw material side active roller, the working execution mechanism, the finished product side active roller and the second balancing guide roller in sequence.

[0013] In this application, the Y-axis direction is defined as the transmission direction of the coil, the X-axis direction is perpendicular to the Y-axis direction in the horizontal plane, and the Z-axis direction is perpendicular to the Y-axis direction in the vertical plane. The device also includes an external control center for controlling the operation of the entire device, which belongs to the prior art and does not belong to the improvement point of the present invention, and is not described in detail here. The active roller on the raw material side and the active roller on the finished product side are used in combination to pull the coil forward and reverse the coil, and the coil is stopped at the position required by the process, so that the working actuator can process the coil. In the self-balancing mechanism, when the active rollers on the raw material side and the active rollers on the finished product side cooperate to pull the material forward, the balancing slider will move to the left on the balancing guide rail, otherwise, when the active rollers on the raw material side and the active rollers on the finished product side cooperate to pull back in the reverse direction, the balancing slider will move to the right on the balancing guide rail, and the coil will perform differential compensation movement, but the coil length of the raw material side balancing area plus the finished product side balancing area is always equal to the total length of the coil in the self-balancing mechanism, and the tension of the coil is kept constant at the same time, that is: with the working actuator as the center line, the coil can self-maintain the principle of left and right material growth and decline balance in the processing area of ​​the center line, and physical balance can be achieved without any external power transmission.

[0015] Furthermore, the self-balancing mechanism further comprises a third balancing guide roller, a fourth balancing guide roller, a fifth guide roller and a sixth guide roller, wherein the third balancing guide roller and the fourth balancing guide roller are fixedly arranged on the balancing slide block, and the fifth guide roller and the sixth guide roller are arranged on the left and right sides of the balancing slide rail respectively; the coil passes through the first guide roller, the first balancing guide roller, the fifth guide roller, the third balancing guide roller and the second guide roller in sequence to form a second raw material side balancing area, and the processed coil passes through the third guide roller, the fourth balancing guide roller, the sixth guide roller, the second balancing guide roller and the fourth guide roller in sequence to form a second finished product side balancing area, and the coil paths of the second raw material side balancing area and the second finished product side balancing area are arranged in parallel along the Y-axis direction.

[0016] Furthermore, the surfaces of the active roller on the raw material side and the active roller on the finished product side are both sandblasted, and a pressing rubber roller and a rubber roller cylinder are provided on one side of the active roller on the raw material side and the active roller on the finished product side, the peripheral surface of the active roller on the raw material side or the active roller on the finished product side is in contact with the peripheral surface of the pressing rubber roller, the pressing rubber roller and the rubber roller cylinder are drivingly connected, and the rubber roller cylinder controls whether the pressing rubber roller performs a pressing operation on the coiled material. Sandblasting the surfaces of the active roller on the raw material side and the active roller on the finished product side can increase the friction coefficient between the coiled material and the roller surface, and can effectively avoid any slipping phenomenon; by using the setting of the rubber roller cylinder, a functional selection can be made as to whether the coiled material is pressed.

[0017] Furthermore, the traction mechanism includes a raw material traction assembly and a finished product traction assembly, the raw material traction assembly is arranged on the left side of the working execution mechanism, and the finished product traction assembly is arranged on the right side of the working execution mechanism; the raw material traction assembly and the finished product traction assembly both include a traction active roller, a traction pressure roller and a traction motor, the traction active roller is drivingly connected to the traction motor, the circumference of the traction active roller is in contact with the circumference of the traction pressure roller, and the traction active roller and the traction pressure roller cooperate to pull the coil.

[0018] Furthermore, the speed sensor includes an acceleration sensor and a deceleration sensor, and the acceleration sensor and the deceleration sensor are respectively arranged at the left and right ends of the balancing slider. In actual applications, the acceleration sensor and the deceleration sensor are both connected to the external control center of the device. When both the acceleration sensor and the deceleration sensor have signals, the control center can determine that the left and right lengths of the coils in the raw material side balancing area (i.e., the first raw material side balancing area or the second raw material side balancing area) and the coils in the finished product side balancing area (i.e., the first finished product side balancing area or the second finished product side balancing area) are close to balance; when the coils in the raw material side balancing area are less than those in the finished product side balancing area, the balancing slider will deviate to the left, causing the deceleration sensor to be in the OFF state and the acceleration sensor to be in the ON state, at which time the control center will speed up the feeding speed of the raw material side active roller and the finished product side active roller; on the contrary, if the balancing slider deviates to the right, the acceleration sensor is in the OFF state and the deceleration sensor is in the ON state, that is, the raw material side balancing area is more than the finished product side balancing area, and the control center will slow down the feeding speed of the raw material side active roller and the finished product side active roller.

[0019] Furthermore, the working execution mechanism includes one of a die-cutting mechanism, a creasing mechanism, a laser cutting mechanism, a punching mechanism, a glue dispensing mechanism and an appearance CCD detection mechanism.

Since the Z-axis moving assembly is arranged on the X-axis slider, the X-axis slider drives the Z-axis moving assembly and the lettering knife to slide along the X-axis slide rail together, the structure is simple and the movement control method is simple.

[0022] Furthermore, the unwinding mechanism includes a discharge shaft and a correction unit, both of which are arranged on the frame, the correction unit is arranged above the discharge shaft, the discharge shaft is movably connected to the frame, the coil is placed on the discharge shaft, the correction unit corrects the deviation of the coil in real time, and the coil is unrolled and transmitted to the traction mechanism located on the left side of the working execution mechanism through the correction unit; the device also includes a winding mechanism, which is arranged on the frame, and the finished product after processing is transmitted to the winding mechanism for winding through the traction mechanism on the right side of the working execution mechanism. The discharge shaft can adopt an air expansion shaft, and the discharge shaft and the correction unit are both direct applications of the prior art, and the existing on-the-go correction device can be used. The correction component provides the required correction control to help the production line operate effectively and efficiently, but its specific structure does not belong to the main improvement point of this application, and will not be described in detail here. In the general processing method, the winding mechanism includes a material winding shaft and a waste winding shaft. The finished product is wound into the material winding shaft, and the edge material is wound into the waste winding shaft. The product and waste are automatically wound into the finished product and the waste is wound up respectively, which improves the processing efficiency.

[0023] The advantage of the present invention is that the coil can perform path difference compensation movement in the self-balancing mechanism of the device, and the coil can still achieve a physical balance of left and right growth and decline in the working area when frequently performing forward and reverse movements, thereby keeping the total length of the material path equal and the tension of the coil constant. There is no need to set a spring or vacuum adsorption structure to provide additional power, and the tension of the coil can be automatically adjusted to meet the processing requirements, thereby realizing a coil processing method without vacuum, noise, and spring stretching.
