Description

Technical Field

[0001] The invention relates to a winding device, in particular to gap cutting and winding. Background Art

[0002] In the label industry, generally speaking, there is a layer of anti-sticking backing paper and another layer of backing paper. This material is die-cut into a required shape and applied to the labeling machine to attach to the packaging box. For this kind of label, the patterns of the labels are usually arranged at a certain distance during die-cutting, and then the waste materials outside the pattern are collected and processed, leaving the complete pattern shape on the backing paper to facilitate the subsequent labeling operation.

[0003] In the production process, the main material is rolled, and then rolled into small rolls for labeling machines. When rolling into small rolls, the machine is usually stopped manually for cutting, unloading and packing.

[0004] For example, patent document CN104555528A solves the problem of fully automated winding operations, but its defect lies in a high-speed cutting knife. The cutter generally performs rapid cutting operations in a sawtooth shape. During high-speed production, a real-time cutting operation usually destroys the complete pattern. Once destroyed, two label products will be lost. For high-value labels, there is an unacceptable loss. In addition, for products such as RFID tags, which contain chips and antennas for the chips, they are metal products. Naturally, when the production equipment cannot ensure cutting at a certain position, if the chip is cut, the life of the cutter will be greatly shortened. Summary of the invention

[0005] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a gap cutting and winding machine, which can wind up materials, especially materials with gaps between units (such as RFID tag products), and can ensure that the cutting is done at the gap between the units of the material, avoiding damage to the material and damage to the tool.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The gap cutting reel includes a reeling mechanism, a cutting mechanism and a material unit detection sensor. The reeling mechanism includes a reeling shaft, a turntable and a reeling motor. The reeling shaft is connected to the reeling motor by transmission. The reeling shaft is arranged on the turntable. At least two reeling shafts are arranged. The reeling mechanism is at least equipped with a shaft reeling station and a shaft waiting station. The reeling shaft on the turntable switches between the stations. The cutting mechanism is arranged at the reeling mechanism. The characteristics are: the material unit detection sensor is arranged on the feeding path before the cutting mechanism. The material unit detection sensor is adjusted and arranged along the front and rear positions of the feeding path on the feeding path. The material unit detection sensor is connected to the reeling motor. The gap cutting reeling machine can switch the reeling, and receive the unit quantity signal on the material through the material unit detection sensor, and then cooperate with the reeling motor to drive and pull the reeling shaft, so that the reeling shaft can reel the material to a suitable position for cutting, so that the material can be cut at the gap position between the units. When adjusting the machine, if the cutting position is not at the gap, the front and rear positions of the material unit detection sensor can be adjusted.

[0008] The following optimizations or supplements can be made to the above technical solution.

[0009] For example, the cutting mechanism includes an upper movable frame and a lower movable frame, the upper movable frame is provided with a pressure roller and an upper knife, the lower movable frame is provided with a lower knife, the pressure roller is arranged corresponding to the winding shaft at the shaft winding station, and the upper knife and the lower knife are arranged in coordination. The pressure roller can press on the winding shaft so that the winding shaft can be smoothly wound in the initial state, and can also clamp the material so that the material can be cut smoothly and stably. The reciprocating movement of the upper movable frame realizes the back and forth movement of the pressure roller and the upper knife. The reciprocating movement of the lower movable frame realizes the back and forth movement of the lower knife, and cooperates with the closing and separation of the upper knife to realize the cutting and resetting of the material.

[0010] For example, the upper movable frame is provided with a linear guide rod for vertical lifting, and the lower movable frame is provided with a swing arm. The upper movable frame can be lifted and lowered along a straight line, and the lower movable frame can swing.

[0011] In addition, the upper movable frame is also connected with a lifting brush. The lifting brush rises and falls relative to the pressure roller on the upper movable frame. After the material is cut, the lifting brush can brush the head of the material that needs to be rewound onto the reel at the reel reeling station, making the reel smoother and more stable during the initial rewinding, and preventing the head of the material from turning over during rewinding. The entire rewound product is neat, beautiful and tidy.

[0012] Further optimization, the lifting brush is connected to the upper knife, and the structure is more compact; the upper knife will also rise and fall to drive the lifting brush to rise and fall.

[0013] For another example, the upper knife uses a flat blade, and the lower knife uses a circular blade. The circular blade is connected to a transverse moving seat, which is arranged on a lower movable frame. The flat blade plate and the circular blade cooperate in shearing. The transverse moving seat moves back and forth horizontally on the lower movable frame, driving the circular blade to move back and forth horizontally, and cooperate to cut the material. The upper blade and the lower blade cooperate in shearing, and the cut of the material is flat, smooth, and burr-free. The rolling of the circular blade cooperates with the transverse blade of the flat blade plate to shear more smoothly.

[0014] Further optimization, the installation shaft of the circular knife is set on the connecting plate, the connecting plate is installed on the longitudinal guide shaft, the longitudinal guide shaft is configured on the circular knife bracket, the connecting plate is connected to the longitudinal ejection cylinder, the connecting plate is also connected to the return spring, and the longitudinal ejection cylinder is connected to the transverse moving seat. When the circular knife and the flat knife plate are cutting, the circular knife and the flat knife plate are kept close to each other under the action of the return spring, forming a shear force, which has a better effect and the cut of the material is flatter and smoother. Under the action of the longitudinal ejection cylinder, the circular knife can be pushed forward, and the circular knife will be separated from the flat knife plate. After the circular knife moves smoothly to one side of the flat knife plate, the longitudinal ejection cylinder returns to its original position, and the shear force is maintained under the action of the return spring. This optimized structure realizes the clutch of the circular knife and the flat knife plate, making their cooperation smoother, maintaining a good shear force during cutting, and the cutting effect is better.

[0015] Further optimization is performed, and a lifting and ejecting cylinder is installed on the transverse moving seat, and the lifting and ejecting cylinder is connected to a support plate through transmission, and an adjustable plate is connected to the support plate, and the longitudinal ejecting cylinder and the circular knife bracket are installed on the adjustable plate. The circular knife is also connected to a pressure wheel through transmission, and the pressure wheel is coaxially arranged with the circular knife, and the pressure wheel cooperates with the flat knife plate. The lifting and ejecting cylinder machine can drive the circular knife to rise and fall relatively, and in addition, the position of the adjustable plate on the support plate can also be adjusted up and down to meet the needs of machine adjustment. The pressure wheel can press on the flat knife plate when cooperating, and during the transverse movement process, the pressure wheel presses on the flat knife plate and rolls frictionally, and the pressure wheel drives the circular knife to rotate, so that the circular knife can cut with the flat knife plate more smoothly.

[0016] In addition, the gap cutting and winding machine also includes a material storage rack, a deviation correction device and a slitting device, and the material unit detection sensor is configured between the deviation correction device and the slitting device. The structural layout is more reasonable. The material storage rack can meet the requirements of non-stop winding. When the gap cutting and winding machine is working, the host (generally referring to the main equipment of the printing press) does not need to be stopped.

[0017] Among them, the structure is optimized, the winding mechanism is equipped with a shaft winding station and a shaft waiting station, two winding shafts are arranged on the turntable, and the two winding shafts are switched alternately between the shaft winding station and the shaft waiting station.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation mode of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0029] Referring to the accompanying drawings, in the embodiment of the present embodiment, the gap cutting and winding machine includes a winding mechanism, a cutting mechanism, a traction device 300 and a material unit detection sensor 800 (such as a label sensor). The winding mechanism includes winding shafts 501, 502, a turntable 500 and a winding motor. The winding shaft is connected to the winding motor by transmission, and the winding shaft is driven to rotate by the winding motor to achieve winding. The winding shafts 501, 502 are arranged on the turntable 500, and at least two winding shafts 501, 502 are arranged. The winding mechanism is at least equipped with a shaft winding station A and a shaft waiting station B. The winding shaft on the turntable 500 switches between the stations, and the position of each winding shaft on it changes through the rotation of the turntable, and each winding shaft switches its position between the stations. The rotation of the turntable can be configured with a corresponding motor drive. In addition, the winding shafts corresponding to the winding motors can be configured one by one, or all winding shafts can share a machine winding motor. The cutting mechanism is arranged at the winding mechanism so as to cut the wound material. The winding shafts 501 and 502 can be air-inflated shafts or other types of winding shafts. The traction device includes a traction motor and a traction roller. The traction motor (such as a servo motor) is connected to the traction roller through a transmission, and the material is pulled forward through the traction device.

[0030] The material unit detection sensor 800 is arranged on the feeding path before the cutting mechanism, so that when the material is pulled and fed, it is detected by the material unit detection sensor 800 to obtain the material length or unit number (such as the number of labels). For example, label materials have independently arranged units on them, and the material unit detection sensor can obtain the number of labels passing through. For example, the normal number of rolled labels is 1,000. It can be set that when the number of rolled labels reaches 999, the equipment will enter the search for the last label. In order to find it more accurately, it will generally enter a slowdown and precise search. When the last label (the 1,000th unit) is detected, the rolling will stop and prepare for cutting.

[0031] The material unit detection sensor 800 is set to adjust the front and rear positions along the feeding path. If the cut edge (i.e., the material cut edge) is not in the gap between the material units after cutting, the front and rear positions of the material unit detection sensor 800 can be adjusted until the cut end is just in the gap position. The material unit detection sensor 800 is connected to the traction motor (not shown) of the traction device 300. When the material unit detection sensor 800 (such as a label sensor) detects and finds a set number of material units such as the number of labels, it feeds back a signal to the traction motor, and the traction motor stops working. Then the turntable 500 rotates, and the cutting mechanism cooperates to cut.

[0032] When it is working, the material unit detection sensor 800 searches for and detects the units on the material. When the set number of units is reached, the traction motor stops working and starts cutting. The turntable 500 rotates, and the winding shaft that has completed winding is rotated to the position of the shaft waiting station B, and the other winding shaft is rotated to the position of the shaft winding station A. The material between the two winding shafts will be cut by the cutting mechanism. If the cutting position is not in the gap position, the front and rear positions of the material unit detection sensor can be adjusted. After cutting, the winding shaft at the shaft waiting station B will complete the winding of the tail of the material or manually handle it; the winding shaft at the shaft winding station A will start a new round of winding of the material.

[0033] The intended effect is that the gap cutting and winding machine can switch winding, and different winding shafts are rotated alternately, and the unit number signal on the material is received through the material unit detection sensor, and then the winding motor drives the winding shaft so that the winding shaft can wind the material to the appropriate position for cutting, so that the material can be cut at the gap position between the units, and the turntable moves the wound winding shaft to the shaft waiting position before cutting. When adjusting the machine, if the cutting position is not at the gap, the front and rear positions of the material unit detection sensor can be adjusted. It can ensure that the cutting is at the gap between the units of the material during cutting, avoiding damage to the material and damage to the tool. Not only does it achieve the production host without stopping the operation, but its material (i.e. material) loss is minimized, and the finished product of the winding operation is more in line with the subsequent production process.

[0034] The following optimization or further explanation may be performed based on the embodiment.

[0035] For example, the cutting mechanism includes an upper movable frame 605 and a lower movable frame 701. The upper movable frame 605 is provided with a pressure roller 604 and an upper knife 611, and the lower movable frame 701 is provided with a lower knife 715. The pressure roller 604 is arranged corresponding to the winding shaft at the shaft winding station A, and the upper knife 611 is arranged in coordination with the lower knife 715. The pressure roller 604 can be pressed on the winding shaft and rotated so that the winding shaft can be smoothly wound in the initial state. In addition, it can also clamp the material so that the material can be cut smoothly and stably. The reciprocating movement of the upper movable frame 605 realizes the back and forth movement of the pressure roller 604 and the upper knife 611. The reciprocating movement of the lower movable frame 701 realizes the back and forth movement of the lower knife 715, and cooperates with the closing and separation of the upper knife 611 to realize the cutting and resetting of the material.

[0036] The upper movable frame 605 and the lower movable frame 701 can move in many reciprocating ways, such as linear or swinging. For example, in the figure, the upper movable frame 605 is arranged on a linear guide rod 603 for vertical lifting, and a guide sleeve 602 can be set for connection, and the lower movable frame 701 is set as a swing arm. The upper movable frame 605 can move up and down along a straight line, while the lower movable frame 701 can swing; the lifting of the upper movable frame 605 and the swinging of the lower movable frame 701 can be driven by a cylinder or a motor respectively.

[0037] In addition, the shaft winding station A is also equipped with a brush 610, which is set to rise and fall. The brush is set in conjunction with the winding shaft at the shaft winding station, so that after the material is cut, the head of the material that needs to be rewound can be brushed onto the winding shaft at the shaft winding station A, so that the winding shaft can be smoother and more stable during the initial winding, and the head of the material will not roll over during winding, and the entire wound product is neat, beautiful and tidy. The brush 610 can be set to rise and fall separately, or the brush 610 can be connected to the upper movable frame 605, and the upper movable frame 605 can be raised and lowered by the brush 610. Further optimization, the brush 610 is connected to the upper knife 611, and the structure is more compact; the upper knife 611 will also rise and fall, driving the brush 610 to rise and fall synchronously. The lifting of the brush 610 can be driven by a cylinder 608 or a motor. In the figure, the brush is connected to the upper movable frame through the cylinder, and the brush is connected to the rear side of the upper knife (toward the direction of the winding shaft of the shaft winding station). The structure is reasonable and compact, and the brush is located between the upper knife and the winding shaft of the shaft winding station. Generally, a tube such as a paper tube is placed on the winding shaft for winding, and glue, hot melt glue, or double-sided tape is applied on the tube. Alternatively, as not shown in the figure, the shaft winding station is also equipped with an electrostatic generator, which is arranged to be lifted and lowered, and is arranged in coordination with the winding shaft at the shaft winding station. When the electrostatic generator is lifted and lowered, it can move to the winding shaft to generate static electricity for the paper tube on the winding shaft. It can also brush the head of the material that needs to be rewound onto the winding shaft at the shaft winding station A after the material is cut, so that the winding shaft can be smoother and more stable during the initial winding, and the head of the material will not roll over during winding, so that the entire product after winding is neat, beautiful and tidy.

[0038] For another example, one of the upper knife 611 and the lower knife 715 uses a flat knife plate, and the other uses a round knife. The round knife is connected to the transverse moving seat 704, and the transverse moving seat 704 is arranged on the lower movable frame 701, and the flat knife plate cooperates with the round knife in shearing. The transverse moving seat 704 moves back and forth laterally on the upper movable frame 605 or the lower movable frame 701, and the transverse movement of the transverse moving seat 704 can be driven by a cylinder (such as a rodless cylinder 702) or a motor or a module. The transverse moving seat 704 drives the round knife to move back and forth laterally to cooperate in cutting the material. The upper knife 611 and the lower knife 715 cooperate in shearing, and the cut of the material is flat, smooth, and free of burrs. When the round knife rolls and cooperates with the transverse blade of the flat knife plate, the shearing is smoother. In the figure, the upper knife uses a flat knife plate (i.e., a flat knife) and the lower knife uses a round knife.

[0039] Further optimization, the installation axis of the circular knife is set on the connecting plate 710, and a clutch transmission device is provided between the connecting plate 710 and the transverse moving seat 704. The clutch transmission device enables the circular knife to move forward and backward along the installation axis; the circular knife can be moved forward or backward through the clutch transmission device; there are many types of clutch transmission devices, such as cylinders, solenoid valves, or motors. For example, in the figure, the clutch transmission device includes a longitudinal ejection cylinder (714) and a return spring (711), the connecting plate 710 is installed on the longitudinal guide shaft 709, the longitudinal guide shaft 709 is arranged on the circular knife bracket 708, the connecting plate 710 is connected to the longitudinal ejection cylinder 714, the connecting plate 710 is connected to the return spring 711, and the longitudinal ejection cylinder 714 is connected to the transverse moving seat 704. When the circular knife and the flat knife plate are cutting, the circular knife and the flat knife plate are kept close to each other under the action of the return spring 711, and are moved backward through the clutch transmission device to keep close to each other, forming a shearing force, which has a better effect and makes the cut of the material flatter and smoother. Under the action of the longitudinal ejection cylinder 714, the circular knife can be pushed forward, and the circular knife will be separated from the flat knife plate. After the circular knife is smoothly moved to one side of the flat knife plate, the longitudinal ejection cylinder 714 returns, and the circular knife leans against the flat knife plate under the action of the return spring to maintain the shearing force. This optimized structure realizes the clutch of the circular knife and the flat knife plate, making their cooperation smoother, maintaining a good shearing force during cutting, and having a better cutting effect. A transverse guide shaft 703 can be set for the transverse moving seat 704 to move stably.

[0040] It can be further optimized, the horizontal moving seat 704 is equipped with a lifting and ejecting cylinder 705, the lifting and ejecting cylinder 705 is connected to the support plate 706, the support plate 706 is connected to the adjustable plate 707, and the longitudinal ejecting cylinder 714 and the circular knife bracket 708 are installed on the adjustable plate 707. The circular knife is also connected to the pressing wheel 716, which is coaxially arranged with the circular knife, and the pressing wheel 716 cooperates with the flat knife plate. The lifting and ejecting cylinder 705 can drive the circular knife to rise and fall relatively. In addition, the position of the adjustable plate 707 on the support plate 706 can also be adjusted up and down. The adjustable plate 707 can be adjusted in position on the support plate 706 by means of a long hole with fasteners to meet the machine adjustment requirements and the closing requirements with the upper knife 611. The pressure wheel 716 can be pressed on the flat knife plate when in cooperation. During the lateral movement, the pressure wheel 716 is pressed on the flat knife plate to rub and roll. The pressure wheel 716 drives the circular knife to rotate together, allowing the circular knife to roll smoothly and make the circular knife cut more smoothly with the flat knife plate.

[0041] In addition, the gap cutting and winding machine also includes a material storage rack 100, a deviation correction device 301 and a slitting device 400. The material storage rack is connected to the traction device 300, the traction device is connected to the deviation correction device, the deviation correction device is connected to the slitting device, and the material unit detection sensor 800 is arranged between the deviation correction device and the slitting device, that is, it is located on the material path between the deviation correction device and the slitting device. The structural layout is more reasonable. The material storage rack can meet the requirements of non-stop winding, and the main machine does not need to be stopped when the gap cutting and winding machine is working. The material storage rack, the deviation correction device, the traction device and the slitting device are all mature technologies and will not be described in detail.

[0042] Among them, the structure is optimized, the winding mechanism is equipped with a shaft winding station A and a shaft waiting station B, two winding shafts are set on the turntable, and the two winding shafts switch alternately between the shaft winding station A and the shaft waiting station, and the structure is more reasonable and compact. Further optimization, the turntable is equipped with a locking device, such as setting a notch on the turntable, setting a locking block on the frame, and the locking block is matched with the notch.

[0043] The above is a preferred embodiment of the present invention, but it should be noted that the protection scope of the present invention is not limited thereto. For those skilled in the art, under the premise of not departing from the equivalent inventive concept of the technical scope disclosed by the present invention, several improvements and modifications or equivalent substitutions can be made, which are also regarded as the protection scope of the present invention.
