Description

Technical Field

[0001] This utility model relates to the field of label feeding technology, and in particular to a side-peeling label machine. Background Technology

[0002] A label is a small sticker or piece of paper used to identify, classify, describe, or provide information. It is typically attached to the surface of an object and contains information such as text, images, barcodes, and serial numbers. A label peeler is a mechanical device used to peel labels from label rolls or reels and deliver them to downstream applications. A label peeler includes a frame and, mounted on the frame, a feeding assembly, a peeling assembly, a receiving assembly, and a waste collection wheel. Its principle is that the label strip placed on the feeding assembly is peeled off in the peeling assembly. The peeled label is received by the receiving assembly, then removed by the label applicator and affixed to the product. The remaining label strip is collected by the waste collection wheel.

[0003] Side labeling has always been a challenging step in automated labeling production lines. Existing label peelers typically peel labels horizontally, requiring the labeling mechanism to first pick up the label using a vacuum nozzle and then rotate the entire mechanism by a specific angle (e.g., 90°) to attach the label to the vertical side of the product. This rotary labeling method has several inherent drawbacks: First, the mechanism's motion is complex and its dynamic response is slow, limiting the overall production cycle time; second, label misalignment due to inertia or vibration during rotation makes it difficult to guarantee labeling accuracy; furthermore, the rotating mechanism occupies a large space and has a complex mechanical structure, increasing both equipment manufacturing costs and subsequent maintenance difficulties. Therefore, the industry urgently needs a solution that can directly peel and label from the side without rotation, offering a simpler structure, higher accuracy, and faster speed. Utility Model Content

[0004] Therefore, it is necessary to provide a side-peeling machine that can directly peel off the label from the side to address the problem of inconvenience in side labeling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a side-peeling label machine, comprising: a vertical plate and a feeding shaft, a vacuum adsorption label pressing section, a label peeling section, a discharge platform section, a pulling section, and a bottom paper receiving shaft arranged sequentially on the vertical plate; the label peeling section includes a vertical guide and a movable bracket that reciprocates along the vertical direction of the vertical guide; the movable bracket is provided with a vertical peeling blade; the anti-sticking platform of the discharge platform section and the vertical peeling blade are on the same vertical plane; the label peeling section also includes a screw drive mechanism that drives the movable bracket to slide along the vertical guide, so that the vertical peeling blade peels off the label and conveys it to the anti-sticking platform; and also includes a material-free detection section located between the label pressing section and the label peeling section.

[0006] Furthermore, the movable bracket is equipped with a small-diameter connecting rod and a large-diameter connecting rod that rotate within it. When the free end of the label backing paper is sequentially wound around the small-diameter connecting rod and the large-diameter connecting rod, the vertical peeling blade bends the label backing paper.

[0007] Furthermore, it also includes a first transition roller and a paper pressing roller located on both sides of the vacuum adsorption label pressing section. The free end of the label backing paper passes around the upper end of the first transition roller, passes through the vacuum adsorption label pressing section, and then passes around the lower end of the paper pressing roller, so that the paper pressing roller tightens the label backing paper.

[0008] Furthermore, a second transition roller is provided on the vertical plate at the upper end of the movable support, which is on the same horizontal plane as the first transition roller, and the side of the second transition roller is on the same vertical plane as the end face of the vertical peeling blade.

[0009] Furthermore, the vertical peeler has symmetrically arranged connecting holes on its end face, and adjusting plates are provided on both sides of the vertical peeler. The adjusting plates have strip-shaped adjusting holes at both ends corresponding to the connecting holes. Both adjusting plates are provided with pressing hinges, and the pressing hinges are provided with pressure plates for pressing the labels.

[0010] Furthermore, the material-free detection unit includes a photoelectric mounting plate, which has several mounting and positioning holes, and a photoelectric switch that is connected to two of the mounting and positioning holes by screws.

[0011] Furthermore, the lead screw drive mechanism includes a lead screw stepper motor located on the back of the vertical plate. The lead screw of the lead screw stepper motor is provided with a lead screw moving seat driven by the lead screw stepper motor. The lead screw moving seat is provided with a thrust plate that passes through the vertical plate and is connected to the moving bracket. The vertical plate is provided with a vertical slot for the thrust plate to move.

[0012] Furthermore, the feeding section includes a feeding seat, which is equipped with an active rubber tube and a driven rubber tube that clamps and rotates with the active rubber tube to feed the material. The feeding seat is also equipped with an adjusting lifting component for adjusting the driven rubber tube so that the driven rubber tube and the active rubber tube clamp the bottom paper. The vertical plate is equipped with a belt and motor drive mechanism for driving the active rubber tube and the bottom paper take-up shaft to rotate. An L-shaped guide plate is provided on the side wall of the feeding seat at the feeding end. A guide groove is opened on the upper surface of the L-shaped guide plate along the length direction, and threaded connection holes are opened at equal intervals along the length direction in the guide groove. T-shaped stops with adjustable positions are provided at both ends of the guide groove. The T-shaped stops have strip countersunk grooves. The T-shaped stops are fixed to the L-shaped guide plate by screws passing through the strip countersunk grooves and connecting to one of the threaded connection holes.

[0013] Furthermore, the vertical guide includes two vertical slide rails located on both sides of the vertical slot opening. The upper and lower ends of the two vertical slide rails are provided with slide rail blocks, and the two vertical slide rails are slidably provided with a slider group connected to the movable bracket; the vertical plate is provided with a limiting groove for positioning the two vertical slide rails.

[0014] This invention has the following advantages: It adopts a vertically reciprocating label peeling part, and through a screw drive mechanism, it precisely controls the movement of the moving bracket and the vertical peeling blade on it along the vertical guide to move up and down. Working in conjunction with the anti-sticking platform fixed on the same vertical plane, it can directly peel the label from the backing paper and transport it to the labeling position, realizing efficient direct side peeling and labeling. It eliminates the rotation action required after picking up the label in the traditional process, simplifies the labeling process, greatly increases the upper limit of the labeling cycle time, and significantly improves production efficiency.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a side-peeling label machine, which includes a vertical plate 10 and, sequentially arranged on the vertical plate 10, a feeding shaft 20, a vacuum adsorption label pressing section 30, a label peeling section 40, a discharge platform section 50, a pulling section 60, and a bottom paper receiving shaft 70. A control device 80, equipped with a touch screen, is provided at the top of the vertical plate 10 to control the operation of electrical components. The label tape is placed on the feeding shaft 20, and the free end of the label tape passes sequentially through the vacuum adsorption label pressing section 30, the label peeling section 40, and the discharge platform. When the labeling section 50, the pulling section 60, and the bottom paper receiving shaft 70 pass through the vacuum adsorption label pressing section 30, the material strip is adsorbed by the vacuum suction plate. The label peeling section 40, the pulling section 60, and the bottom paper receiving shaft 70 move simultaneously to peel off the label. The peeled label is received by the discharge platform section 50. The bottom paper receiving shaft 70 winds up the bottom paper of the material strip. The label is picked up by the labeling adsorption mechanism and attached to the vertical surface of the product. When the label peeling section 40 retracts, the pressure cylinder of the vacuum adsorption label pressing section 30 drives the pressure plate to press the material strip tightly onto the vacuum suction plate to prevent the material strip from retracting.

[0022] To enable side-peeling of labels, allowing the label adsorption mechanism to directly adhere the label to the vertical surface of the product, the label peeling unit 40 includes a vertical guide 41, a movable bracket 42, and a screw drive mechanism 43. The screw drive mechanism 43 drives the movable bracket 42 to move up and down along the vertical guide 41. The vertical guide 41 includes two spaced vertical slide rails, each with a slide rail stop at both ends. Sliding sliders connected to the movable bracket 42 slide along the two vertical slide rails. The vertical plate 10 has limiting grooves for positioning the two vertical slide rails, facilitating installation and positioning. The slide rail stops effectively prevent the sliders from sliding off the vertical slide rails, ensuring the stability and safety of the equipment. The sliders, connected to the movable bracket 42, move smoothly up and down along the two vertical slide rails under the drive of the screw drive mechanism 43, achieving precise vertical positioning of the label peeling unit 40 and providing reliable guidance for side-peeling.

[0023] In addition, the movable support 42 is equipped with a vertical peeling blade 44. The anti-sticking platform of the discharge platform 50 is on the same vertical plane as the vertical peeling blade 44. A small-diameter connecting rod 45 and a large-diameter connecting rod 46 are rotatably provided inside the movable support 42. When the free end of the label backing paper is wrapped around the small-diameter connecting rod 45 and the large-diameter connecting rod 46 in sequence, the vertical peeling blade 44 bends the label backing paper, which can more smoothly separate the label and the backing paper, improving the efficiency and accuracy of peeling the label.

[0024] In an optional embodiment, to prevent the label tape wrapped around the vertical peeler 44 from shifting and causing the label backing paper to curl up and detach from the vertical peeler 44 during retraction, for this purpose, as follows: Figure 4As shown, symmetrically arranged connecting holes are provided on the end face of the vertical peeler 44, and adjusting plates 440 are provided on both sides of the vertical peeler 44. Each adjusting plate 440 has strip-shaped adjusting holes at both ends corresponding to the connecting holes. Both adjusting plates 440 are equipped with clamping hinges 441, and each clamping hinge 441 has a pressure plate 442 for pressing down on the label. When the equipment is running, the pressure plate 442 presses down on the label, ensuring that the label strip remains in close contact with the vertical peeler 44, effectively preventing label strip misalignment. Simultaneously, by cooperating with the connecting holes on the end face of the vertical peeler 44 through the strip-shaped adjusting holes at both ends of the adjusting plate 440, the position of the adjusting plate 440 can be adjusted according to different specifications of label strips, thereby adjusting the degree of pressure of the pressure plate 442 on the label to adapt to various production needs. This design not only improves the stability of label peeling but also enhances the versatility and flexibility of the equipment.

[0025] The lead screw drive mechanism 43 is used to drive the movable support 42 to drive the vertical peeler 44 to peel off the label and transport the label to the anti-sticking platform of the discharge platform section 50, thereby improving the movement accuracy of the movable support 42 and avoiding collisions between the vertical peeler 44 and the anti-sticking platform. To this end, the lead screw drive mechanism 43 includes a lead screw stepper motor 430 located on the back of the vertical plate 10. The lead screw of the lead screw stepper motor 430 is provided with a lead screw moving seat 431 driven by the lead screw stepper motor 430. The lead screw moving seat 431 is provided with a thrust plate 432 that passes through the vertical plate 10 and is connected to the movable support 42. The vertical plate 10 has a vertical slot for the thrust plate 432 to move. The vertical slot is located between two limiting slots. By using the lead screw stepper motor 430 to drive the movement, the movement distance and speed of the movable support 42 can be precisely controlled, thereby ensuring that the vertical peeler 44 accurately peels off the label and transports it to the anti-sticking platform, effectively avoiding collisions between the vertical peeler 44 and the anti-sticking platform. The connection design between the lead screw moving seat 431 and the thrust plate 432 makes the power transmission more stable and reliable, and reduces the error in the transmission process.

[0026] To effectively pull the label tape, a first transition roller 11 and a pressure roller 12 are installed on the vertical plates 10 on both sides of the vacuum adsorption label pressing section 30. The free end of the label backing paper passes over the upper end of the first transition roller 11, through the vacuum adsorption label pressing section 30, and then around the lower end of the pressure roller 12, causing the pressure roller 12 to tighten the label backing paper. A second transition roller 13 is provided on the vertical plate 10 at the upper end of the movable bracket 42, which is on the same horizontal plane as the first transition roller 11, and the side of the second transition roller 13 is on the same vertical plane as the end face of the vertical peeling blade 44. When the label backing paper passes over the first transition roller 11, through the vacuum adsorption label pressing section 30, around the pressure roller 12, and then over the second transition roller 13 in sequence, a stable and reasonable tension system can be formed. This design ensures that the label tape maintains appropriate tension during operation, avoiding problems such as inaccurate label peeling or tape deviation caused by tape slack. Meanwhile, the fact that the second transition roller 13 and the end face of the vertical peeling knife 44 are on the same vertical plane allows the label strip to transition from horizontal to vertical, further ensuring the positional accuracy of the label during the peeling process. This allows the vertical peeling knife 44 to act more precisely at the separation point between the label and the backing paper, thereby improving the working stability and peeling quality of the entire side peeling machine.

[0027] In addition, a third transition roller 14 is provided on the vertical plate 10 between the discharge platform section 50 and the pulling section 60, through which the label backing paper can be pulled to the pulling section 60.

[0028] like Figure 5 As shown, the material pulling section 60 is mainly used to pull the label material tape and drive the bottom paper take-up shaft 70 to wind the bottom paper of the material tape. The material pulling section 60 includes a material pulling seat 61, which is provided with an active adhesive tube 62 and a driven adhesive tube 63 that clamps and rotates with the active adhesive tube 62 to pull the material. The material pulling seat 61 is also provided with an adjusting lifting member 64 for adjusting the driven adhesive tube 63 so that the driven adhesive tube 63 clamps the bottom paper with the active adhesive tube 62. The vertical plate 10 is provided with a belt and motor drive mechanism 65 for driving the active adhesive tube 62 and the bottom paper take-up shaft 70 to rotate. The belt and motor drive mechanism 65 drives the active adhesive tube 62 to drive the driven adhesive tube 63 to rotate and pull the material, while driving the bottom paper take-up shaft 70 to wind the bottom paper of the material tape. The clamping mechanism between the active adhesive stripper 62 and the driven adhesive stripper 63 ensures sufficient friction on the label tape, effectively propelling it forward. The adjustable lifting mechanism 64 allows for flexible adjustment of the clamping force between the driven adhesive stripper 63 and the active adhesive stripper 62 based on the thickness and material of the tape's backing paper, ensuring smooth material pulling and preventing slippage or tape jamming. Belt drive accurately transmits the motor's rotational motion to the active adhesive stripper 62 and the backing paper take-up shaft 70, automating the material pulling and take-up operations and improving the efficiency and production quality of the side-peeling label machine.

[0029] To prevent material strip misalignment during the feeding process, an L-shaped guide plate 66 is provided on the side wall of the feeding seat 61 at the feeding end. A guide groove 660 is formed along the length of the upper surface of the L-shaped guide plate 66, and threaded connection holes are evenly spaced along the length of the guide groove 660. Adjustable T-shaped stops 67 are provided at both ends of the guide groove 660. Each T-shaped stop 67 has a countersunk groove, and screws pass through the countersunk groove and connect to one of the threaded connection holes, thus fixing the T-shaped stop 67 to the L-shaped guide plate 66. The operator can then... Based on the actual width of the strip and operational requirements, the position of the T-shaped stop 67 in the guide groove 660 is adjusted and connected to a suitable threaded connection hole within the guide groove 660. This fixes the T-shaped stop 67 at an appropriate position on the L-shaped guide plate 66. In this way, the T-shaped stop 67 can effectively limit the lateral deviation of the strip during operation, ensuring that the strip is always in the correct position. This avoids problems such as inaccurate label removal and strip damage caused by strip misalignment, further improving the working stability and label removal quality of the side label peeling machine.

[0030] To prevent the label tape from running out or breaking, thus avoiding wasted equipment and affecting label application, resulting in unlabeled products leaving the production line, a material shortage detection unit 90 is installed on the vertical plate 10 between the label pressing section and the label peeling section 40. This material shortage detection unit 90 includes a photoelectric mounting plate 91 with several mounting holes. The mounting plate 91 has photoelectric switches 92 connected to two of these holes via screws. The position of the photoelectric switches 92 on the mounting plate 91 is adjusted according to the width of the label tape, enabling effective detection of the label tape. When the label tape runs out or breaks, the photoelectric switches 92 detect this change promptly and transmit a signal to the equipment control device 80. Upon receiving the signal, the control device 80 immediately stops the equipment to prevent idle operation and also prevent unlabeled products from leaving the production line. The inclusion of this material-free inspection section 90 greatly improves the automation level and operational reliability of the side label peeling machine, reduces production failures and defect rates caused by material strip problems, and further ensures the smooth progress of the production process and the stability of product quality.

[0031] In summary, by employing a vertically reciprocating label peeling unit 40, and precisely controlling the moving bracket 42 and its vertical peeling blade 44 along the vertical guide 41 via a screw drive mechanism 43, and working in conjunction with an anti-sticking platform fixed on the same vertical plane, the label can be directly peeled from the backing paper and transported to the labeling position. This achieves efficient direct side label peeling and application, eliminating the rotation required after picking up the label in traditional processes, simplifying the labeling process, significantly increasing the upper limit of the labeling cycle time, and significantly improving production efficiency.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
