Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of label tearing devices, and particularly relates to a label tearing device, an automatic label tearing and labeling equipment and a method. BACKGROUND

[0002] In order to ensure product traceability, a label is usually provided on the surface of a product by laser printing or pasting, and the label usually has product model information, etc. The entire production process of the product is automatically identified, recorded and controlled through the label barcode. Before the label is pasted, the release paper on the back of the label needs to be torn off, and then the label is pasted on the surface of the product. The traditional manual label tearing and labeling method requires a large amount of labor, and is complicated, labor-intensive and low in work efficiency.

[0003] A label tearing device and packaging equipment are provided in Chinese Patent No. CN202111109866.2, which includes a rack, a positioning mechanism, a label tearing mechanism and an adhesive tape conveying mechanism arranged on the rack. The positioning mechanism is used to position and compress the workpiece. The adhesive tape conveying mechanism is used to convey the adhesive tape to the label tearing mechanism and then convey it back to the adhesive tape conveying mechanism for recycling after the label is torn off. The label tearing mechanism includes a base plate vertically connected to the rack and a moving part horizontally connected to the base plate. The moving part is wound with adhesive tape to tear off the label on the workpiece. The workpiece is compressed and positioned by the positioning mechanism, and then the adhesive tape is conveyed to the label tearing mechanism by the adhesive tape conveying mechanism. The movement of the label tearing mechanism is used to tear off the label on the workpiece.

[0004] However, the above-mentioned device is usually used for wound labels, i.e. several labels are connected and wound into a roll shape. When used, the label paper is compressed and positioned, and then the label is conveyed to the label tearing mechanism by the label conveying mechanism. The movement of the label tearing mechanism is used to tear off the label on the workpiece. However, there are few automatic label tearing structures on the market for independent sheet labels.

[0005] Chinese Patent No. CN201410307473.6 discloses an automatic label tearing device and method. The product with a label is fixed on a test socket. The push-pull device drives the clamping jaw in the clamping jaw assembly to move to a clamping position to clamp the label. The swing assembly drives the clamping jaw to swing to one side to tear one side of the label. The swing assembly is reset, and at the same time, the push-pull device is reset and the rotating assembly drives the test socket to rotate. The direction of rotation of the test socket is opposite to the direction of reset of the swing assembly.

[0006] The Chinese patent with the application number CN201821245489.9 discloses an online label tearing base paper device, which comprises a vertical plate, a pressing mechanism mounted on the vertical plate and an inclined plate. The pressing mechanism comprises a pressing cylinder, a support connected with a first piston rod of the pressing cylinder and a floating pressing plate connected with the support. A tearing cylinder and a floating assembly are mounted on the inclined plate, and a tearing cutter head is connected with a second piston rod of the tearing cylinder. A mechanical hand places double labels on a horizontal plate and a fixed seat. The pressing cylinder is started to drive the support to drive the pressing block of the floating pressing plate to press the base paper that does not need to be torn in the double labels. The tearing cylinder is started to drive the tearing cutter head downward by the second piston rod. The tearing cutter head and the floating block clamp the base paper that needs to be torn. The floating block compresses the first spring to move downward along the linear slide rail to tear the label base paper. The mechanical hand takes away the label. The torn base paper is between the tearing cutter head and the floating block. When the label is taken away, the second piston rod of the tearing cylinder is extended, and the base paper falls into a paper collecting box.

[0007] However, the above-mentioned label tearing device cannot automatically feed the labels, and cannot realize continuous full automation. Therefore, it is necessary to provide a label tearing device with high automation degree and high efficiency. SUMMARY

[0100] In order to make the purpose and technical scheme of the embodiments of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the embodiments of the present application.

[0101] In the description of the present application, it should be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0102] As shown in Figures 1-14 The present application provides a label tearing device, which comprises a feeding mechanism 1, a transfer mechanism 2 and a peeling mechanism 3 fixed on a bottom plate 101; the label to be separated 5 comprises a sheet label 501 and a release paper 502 adhered to each other; the sheet label 501 and the release paper 502 need to be separated, and then the sheet label 501 is pasted on the surface of the product; the feeding mechanism, the transfer mechanism 2 and the peeling mechanism 3 are all fixed on the same bottom plate 101, wherein the label to be separated 5 is placed in the feeding mechanism 1, removed by the transfer mechanism 2, transported to the position of the peeling mechanism 3, and then separated from the sheet label 501 and the release paper 502 by the peeling mechanism 3.

[0103] As shown in Figures 3-6As shown, the feeding mechanism 1 comprises a lifting device and a feeding box 103 fixed on the feeding base plate 102. The feeding box 103 is a box-shaped structure with an open upper end and is spliced by several pieces of sheet metal. The feeding box 103 can accommodate a stack of labels 5 to be separated. A push plate movably arranged in the bottom of the feeding box 103 is provided. The stack of labels 5 to be separated is arranged above the push plate. The lifting device penetrates through the feeding base plate 102 and is fixedly connected with the push plate. The lifting device drives the push plate to move up and down. Specifically, the lifting device is fixedly connected with the push plate and drives the push plate to move up and down, so that the labels 5 to be separated in the feeding box 103 can be lifted to a height higher than the upper surface of the feeding box 103. The lifting device comprises a lifting motor 104 fixed on the lower surface of the feeding base plate 102, and a first lifting shaft 105 and a second lifting shaft 106 respectively arranged on the two sides of the lifting motor 104. The output shaft of the lifting motor 104 penetrates through the feeding base plate 102 and is fixedly connected with the lower surface of the push plate. A bearing seat is provided with a movable lifting shaft. The lifting shaft penetrates through the bearing seat and the feeding base plate 102 and is fixedly connected with the lower surface of the push plate. The lifting shaft can move up and down along the direction of the bearing seat. The two lifting shafts on the two sides function as a guide to prevent the push plate from deviating during the driving of the lifting motor 104.

[0104] A plurality of brush devices 107 are further arranged on the side wall in the feeding box 103. In the embodiment, two brush devices 107 are arranged. The brush device 107 comprises a plurality of brush units arranged in combination and distributed on the two sides of the labels 5 to be separated. The brush device 107 is used to rub the side edges of the labels 5 to be separated during the lifting of the labels 5 to be separated, so as to prevent the labels 5 to be separated from being adhered together.

[0105] A position sensor 109 is further arranged on the side wall in the feeding box 103. The position sensor 109 is used to detect the uppermost label 5 to be separated in the feeding box 103. The position sensor 109 is preferably a laser sensor or a fiber sensor. When feeding is needed, the lifting motor 104 drives the labels 5 to be separated to move upwards until the uppermost label 5 to be separated blocks the light emitted by the position sensor 109. At this time, it is indicated that the feeding position has been reached. The lifting motor 104 stops moving, and the labels 5 to be separated wait to be taken away.

[0106] The first sensor 115 and the material sensor 116 are arranged inside the feeding box 103. The material sensor 116 is arranged on the bottom surface inside the feeding box 103, preferably a laser sensor or a fiber sensor, for detecting whether there is a label 5 to be separated inside the feeding box 103. If there is a label 5 to be separated inside the feeding box 103, the light of the material sensor 116 is blocked. If all the labels 5 to be separated inside the feeding box 103 have been taken out, the light of the material sensor 116 is not blocked, and a signal will be sent to the control end to issue an alarm. The first sensor 115 is arranged on the side surface of the feeding box 103 below, and the lifting sensor 108 is arranged on the side surface of the first lifting shaft 105 and the second lifting shaft 106. The function of the first sensor 115 and the lifting sensor 108 is to determine the lowest position of the lifting device. The first sensor 115 and the lifting sensor 108 are preferably laser sensors or fiber sensors, for detecting the position of the pushing plate and the position of the first lifting shaft 105 and the second lifting shaft 106, and determining the lower limit position.

[0107] The feeding mechanism 1 further comprises a material separating device for separating the label 5 to be separated, which is fixed on the bottom plate 101 above the feeding box 103.

[0108] The material separating device comprises a material separating cylinder 110, a material separating guide rail 114, and a separating piece 112. The separating piece 112 is fixed on the material separating sliding block 113 of the material separating guide rail 114. The material separating sliding block 113 is connected with the pushing shaft of the material separating cylinder 110 through the material separating connecting plate 111. The lower surface of the separating piece 112 is slightly higher than the upper surface of the feeding box 103. The pushing shaft of the material separating cylinder 110 can be extended or retracted to control the movement of the separating piece 112 along the material separating guide rail 114. The separating piece 112 is arranged on the side of the feeding box 103, and the lower surface of the separating piece 112 is slightly higher than the upper surface of the feeding box 103.

[0109] The length of the material separating guide rail 114 basically covers the entire range of the feeding box 103, so that the separating piece 112 can pass through above the entire feeding box 103. According to the adhesion degree between the first label 5 to be separated and the second label 5 to be separated, the distance of the movement of the separating piece 112 can be controlled to ensure that the transfer mechanism 2 takes out only one label 5 to be separated at a time.

[0110] The working principle of the feeding mechanism 1 is as follows: when feeding is needed, the lifting motor 104 drives the push plate to rise, so that the uppermost piece of the label to be separated 5 in the feeding box 103 reaches the position of the in-place sensor 109, then the separating cylinder 110 extends, the separating piece 112 is inserted between the uppermost piece of the label to be separated 5 and the second piece of the label to be separated 5, preventing the occurrence of adhesion when the label to be separated 5 is taken away, after the uppermost piece of the label to be separated 5 is taken away, the separating cylinder 110 is retracted, and the lifting motor 104 drives the push plate to rise by the thickness of a piece of the label to be separated 5 for the next feeding, and the above steps are repeated.

The extension rods of the first shaking cylinder 210 and the second shaking cylinder 211 are arranged opposite to each other and are fixedly connected through a shaking connecting block 212. Therefore, the extension rods of the first shaking cylinder 210 and the second shaking cylinder 211 are matched relative to each other, the suction disc connecting plate 209 and the suction disc connecting plate 205 can be lifted, lowered and slightly moved up and down, that is, the suction disc 206 can be lifted, lowered and slightly shaken up and down, the suction disc 206 is convenient for sucking the labels to be separated 5, and meanwhile, the uppermost label to be separated 5 and the second label to be separated 5 are further prevented from being adhered when the labels to be separated 5 are taken away.

[0114] The working principle of the transfer mechanism 2 is as follows: the transfer cylinder 201 is extended, the suction disc 206 is moved to the upper side of the feeding box 103, the suction disc 206 is lowered, the uppermost first label to be separated 5 is sucked, the suction disc 206 is lifted at the same time, the shaking device controls the suction disc 206 to be slightly shaken up and down, the uppermost label to be separated 5 and the second label to be separated 5 are completely separated, the suction disc 206 is lifted to a specified position, the transfer cylinder 201 is retracted, and the suction disc 206 carries the label to be separated 5 to the upper side of the peeling station.

[0115] As shown in Figures 9-10 The peeling station is provided with a peeling mechanism 3, the peeling mechanism 3 includes a pushing device, a clamping device 303 and a receiving device, and the clamping device 303 and the pushing device are distributed on the upper and lower sides of the receiving device.

[0116] In the moving direction of the label to be separated 5, the receiving device includes an initial receiving plate 304 and a receiving plate 305 provided with a receiving groove, as shown in Figure 12As shown, the width of the receiving groove is slightly wider than the width of the sheet label 501, and the length is slightly longer than the length of the sheet label 501. Preferably, the upper surface of the receiving groove is in a convex sawtooth structure to reduce the contact area with the sheet label 501. Preferably, the initial receiving plate 304 is a metal plate structure, and there is a certain gap between the initial receiving plate 304 and the receiving plate 305. The receiving plate 305 is fixed on the bottom plate 101 by a fixed metal plate, so there is also a certain gap between the receiving plate 305 and the bottom plate 101. The distance between the initial receiving plate 304 and the receiving plate 305 is set so that the clamping device 303 can pass between them without interference.

[0117] The advancing device includes longitudinally and mutually parallel advancing cylinders 301 and advancing guide rails 302. The advancing cylinders 301 include advancing cylinder bodies and advancing cylinder telescopic rods. The advancing guide rails 302 are provided with sliding first and second advancing sliding blocks. The clamping device 303 is fixed on the first and second advancing sliding blocks. Therefore, the advancing cylinders 301 can drive the clamping device 303 to move along the advancing guide rails 302.

[0118] The clamping device 303 includes clamping cylinders 3031, first clamping arms 3033, and second clamping arms 3035. The clamping cylinders 3031 include clamping cylinder bodies and clamping cylinder telescopic rods. The first clamping arms 3033 are fixed on the first advancing sliding blocks and are fixedly connected to the clamping cylinder bodies. The second clamping arms 3035 are fixed on the second advancing sliding blocks and are fixedly connected to the clamping cylinder telescopic rods and the advancing cylinder telescopic rods. The first clamping arms 3033 are fixed between the clamping cylinder bodies and the first clamping connecting blocks 3032. The first clamping arms 3033 are in an L shape and include first clamping arm fixed ends and first clamping arm clamping ends. The first clamping arm fixed ends are fixed on the first clamping connecting blocks 3032, and the first clamping arm clamping ends are perpendicular to the first clamping connecting blocks 3032. The second clamping arms 3035 are fixed between the second sliding blocks and the second clamping connecting blocks 3034. The second clamping arms 3035 are perpendicular to the second clamping connecting blocks 3034 and are in the same vertical plane as the first clamping arm clamping ends. The advancing cylinders 301 and the clamping cylinders 3031 are distributed on both sides of the advancing guide rails 302. The first clamping arms 3033 and the second clamping arms 3035 are perpendicular to the plane formed by the advancing cylinders 301 and the clamping cylinders 3031.

[0119] There is a gap between the first clamping arm 3033 and the second clamping arm 3035, and the gap can be adjusted by the extension and retraction of the clamping cylinder 3031. Specifically, when the advancing cylinder 301 is fixed, since the second clamping arm 3035 is fixed on the second slider, and the second clamping arm 3035 is fixedly connected with the extension and retraction rod of the clamping cylinder 3031 and the extension and retraction rod of the advancing cylinder 301, the position of the second advancing slider and the second clamping arm 3035 remains unchanged. At this time, if the extension and retraction rod of the clamping cylinder 3031 extends, since the first clamping arm 3033 is fixed on the first slider, and is fixedly connected with the body of the clamping cylinder 3031, the first clamping arm 3033 and the first advancing slider will be pushed to move upward, so that the gap between the first clamping arm 3033 and the second clamping arm 3035 is enlarged.

[0120] The peeling mechanism 3 further comprises a waste removal device and a waste box 308 for collecting the release paper 502, the waste box 308 is located below the peeling station, and can surround the four sides of the clamping device 303, the waste removal device is used to push the peeled release paper 502 into the waste box 308. The waste removal device is located above the lower limit position of the clamping mechanism, and the waste removal device comprises a waste removal cylinder 306 and a waste removal push block 307, the waste removal push block 307 covers part of the area of the peeled release paper 502.

[0121] The working principle of the peeling mechanism 3 is as follows:

[0122] In the initial condition, the clamping device 303 is located between the initial supporting plate 304 and the supporting plate 305, more specifically, the first clamping arm 3033 and the second clamping arm 3035 of the clamping device 303 are located between the initial supporting plate 304 and the supporting plate 305, at this time, the clamping cylinder 3031 of the clamping cylinder 3031 is in the extended state, the gap between the first clamping arm 3033 and the second clamping arm 3035 is large enough to allow the release paper 502 of the label to be separated 5 to pass through, and the suction cup 206 in the process of carrying the label to be separated 5, the label to be separated 5 passes above the initial supporting plate 304, and just extends into the gap between the first clamping arm 3033 and the second clamping arm 3035, because the label to be separated 5 includes the sheet label 501 and the release paper 502 which are mutually adhered, wherein the area of the release paper 502 is larger than the area of the sheet label 501, and the edge of the release paper 502 protrudes the edge of the sheet label 501, therefore, in the process of early debugging, the stop position of the suction cup 206 makes the release paper 502 of the label to be separated 5 can extend into the gap between the first clamping arm 3033 and the second clamping arm 3035, and the sheet label 501 does not extend. The suction cup 206 stops the vacuum, the label to be separated 5 falls onto the initial supporting plate 304, the clamping cylinder 3031 retracts, the first clamping arm 3033 and the second clamping arm 3035 clamp the release paper 502, the push cylinder 301 extends, and the clamping device 303 is pushed down. At this time, the first clamping arm 3033 and the second clamping arm 3035 clamp the release paper 502, so that the release paper 502 is peeled off from the sheet label 501, because in the process of peeling, under the condition of inertia, the release paper 502 provides a forward pushing force for the sheet label 501, therefore, the release paper 502 is peeled off from the sheet label 501 at the same time, and the sheet label 501 is driven to advance to the supporting groove of the supporting plate 305. When the release paper 502 is about to be completely peeled off, at this time, the release paper 502 is parallel to the push cylinder 301 and the push guide rail 302 and is in an approximately taut state, the waste cylinder 306 extends, the waste push block 307 pushes the release paper 502 to completely fall off, the clamping cylinder 3031 extends, the first clamping arm 3033 and the second clamping arm 3035 open, and the release paper 502 falls into the waste box 308.

[0123] In order to ensure the peeling effect, preferably, the positions of the first clamping arm 3033 and the second clamping arm 3035 are extremely close to the edge of the receiving plate 305 but do not interfere in the process of rising and falling, and when the release paper 502 is peeled off, the sheet-shaped label 501 can be quickly pushed into the receiving groove. Since the receiving plate 305 provides a receiving force, and the inside of the receiving groove is zigzag-shaped, the contact area is reduced, the sheet-shaped label 501 is prevented from being excessively adhered to the receiving groove, and it is ensured that the sheet-shaped label 501 can be continuously pushed in. Further, the lower surface of the suction cup 206 is extremely close to the upper surface of the initial receiving plate 304, that is, the gap between the lower surface of the suction cup 206 and the upper surface of the initial receiving plate 304 is slightly larger than the thickness of a label to be separated 5. When the release paper 502 is peeled off, due to the presence of the suction cup 206, a slight downward limiting force can be provided to prevent the label to be separated 5 from being excessively raised due to the peeling of the release paper 502, which causes the label to be separated 5 to fail to smoothly enter the receiving plate 305, thereby affecting the peeling effect. At the same time, since the width of the receiving groove is slightly wider than the width of the sheet-shaped label 501, and the length of the receiving groove is slightly longer than the length of the sheet-shaped label 501, the sheet-shaped label 501 itself has a certain adhesion. Therefore, when the sheet-shaped label 501 gradually enters the receiving groove, the receiving groove itself can play a certain limiting role to prevent the sheet-shaped label 501 from being raised or popped out.

[0124] As shown in Figure 13 , all air paths of the label tearing device are controlled by an electromagnetic valve assembly 4. The electromagnetic valve assembly 4 includes a bracket 401 and an integrated base 402 supported by the bracket 401. The integrated base 402 is fixed with an electromagnetic valve group 402.

[0125] The present application also provides an automatic label tearing and labeling device, which comprises the above-mentioned label tearing device; as shown in Figures 15-16 , the device further comprises a labeling device 6, a detection device 7, a pressing device 8 and a conveying device 9.

[0126] The conveying device 9 is used for conveying products. The conveying device 9 is preferably a linear motor. The products are manually loaded on a loading station 11 by a mechanical method, and then conveyed to a labeling station by the conveying device 9 to wait for labeling.

[0127] The labeling device 6 is used for labeling the sheet-shaped label 501 after the release paper 502 is peeled off on the upper surface of the product. Preferably, the labeling device 6 is a four-axis mechanical arm. The end of the four-axis mechanical arm is flexible and can freely adjust the direction and angle, which is more practical.

[0128] The detection device 7 is used to detect the position of the label; the detection device 7 comprises a detection camera which is used to take pictures of the sheet label 501 carried by the labeling device 6 and determine whether it is in place. The four-axis mechanical arm takes the sheet label 501 from the receiving groove of the label tearing device, and then carries it to the detection device 7 first, and the detection camera detects whether the position of the sheet label 501 is in place. If the detection position is qualified, it is carried to the product above to perform labeling. If the detection is not qualified, the position is compensated according to the image taken by the detection camera, the end of the four-axis mechanical arm adjusts the position of the sheet label 501, and then the sheet label 501 is carried to the product above to be attached to the upper surface of the product.

[0129] At this time, since the four-axis mechanical arm only places the sheet label 501 on the upper surface of the product, the degree of adhesion is low, and it is easy to fall off, so a pressing device 8 is arranged above the carrying device 9 to press the label on the upper surface of the product.

[0130] As shown in Figure 16 The pressing device 8 comprises support columns 801 arranged on both sides of the carrying device 9 and a support plate 803 arranged above the carrying device 9, the ends of the support columns 801 are inserted into support tables for fixed connection, the support plate 803 is fixedly connected with the support columns 801 through the support tables, and further comprises a pressing assembly arranged on the support plate 803. The pressing assembly comprises a pressing cylinder 804 and a pressing roller 805, the pressing roller 805 is connected with the output shaft of the pressing cylinder 804 through a fixed frame 806, the fixed frame 806 is U-shaped, and a rotating shaft is arranged at the opening of the fixed frame 806, the pressing roller 805 is arranged on the rotating shaft and rotates around the rotating shaft; the size of the pressing roller 805 is just embedded in the fixed frame 806, so that the pressing roller 805 only rotates in the fixed frame 806 and does not relatively deviate from the fixed frame 806. The pressing roller 805 is higher than the upper surface of the product on the carrying device 9, when the pressing cylinder 804 pushes the fixed frame 806 to descend, the height of the pressing roller 805 is higher than the upper surface of the product and slightly lower than the upper surface of the sheet label 501, so that the pressing roller 805 can apply a large pressure to the sheet label 501 during the return of the product, so that the sheet label 501 is tightly attached to the upper surface of the product.

[0131] The application also provides an automatic label tearing and labeling method, which uses the automatic label tearing and labeling device to label the product, and specifically comprises the following steps:

[0132] Step 1: product feeding, the carrying device 9 moves the product to the labeling station 10;

[0133] Step two: the label separating device peels off the release paper 502 on the label 5 to be separated to obtain a sheet label 501; a plurality of labels 5 to be separated are stacked in the feeding box 103, the lifting device is raised to make one of the labels 5 to be separated higher than the feeding box 103, the transfer mechanism 2 takes away the label to be separated and places it on the peeling station, the first clamping arm 3033 and the second clamping arm 3035 in the clamping device 303 clamp the edges of the release paper 502 of the label 5 to be separated, the push cylinder 301 pushes the clamping device 303 to descend, so that the release paper 502 is peeled off from the sheet label 501 until the sheet label 501 and the release paper 502 are completely separated, the sheet label 501 is driven to the receiving plate 305 and waits for the labeling device 6 to take it away, and the separated release paper 502 enters the waste box 308;

[0134] Step three: the labeling device 6 takes away the sheet label 501, first moves above the detection device 7, and the detection device 7 detects whether the position of the sheet label 501 is in place, if the position detection is qualified, the labeling device 6 places the sheet label 501 on the upper surface of the product;

[0135] Step four: the conveying device 9 pushes the product back to the feeding station 11, and the product passes below the pressing device 8 during the returning process, the pressing device 8 presses the label on the upper surface of the product; wherein the pressing cylinder 804 in the pressing device 8 descends, the height of the pressing roller 805 is higher than the upper surface of the product and slightly lower than the upper surface of the sheet label 501, and the product is pressed by the pressing device 8 during the returning process; the pressing cylinder 804 rises after the product returns to the feeding position;

[0136] Step five: the product is taken down and replaced, and the above steps are repeated.

[0137] The above is only some embodiments of the present application, which are described in detail and in detail, but cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these obvious alternative forms all belong to the protection scope of the present application.
