Description

Technical Field

[0001] This invention belongs to the technical field of flexible material processing equipment, and particularly relates to a rolling labeling device. Background Technology

[0002] In the modern garment manufacturing and automotive interior production industries, CNC cutting machines are widely used for the automated cutting of multi-layer fabrics. A complete CNC cutting machine system usually includes a fabric laying system, a cutting system, and a material receiving system. During the cutting process, cut pieces of different sizes, styles, and batches are mixed together. If each cut piece is not labeled, the subsequent sorting work will be very difficult. Therefore, labeling cut pieces has become the industry standard practice.

[0003] Currently, the mainstream labeling solutions for cutting machines on the market adopt a hybrid electromechanical drive design. The basic structure of this type of solution is as follows: an independent labeling module is installed on the side of the cutting machine head. This module is equipped with a stepper motor and a Z-axis cylinder. The motor is responsible for driving and pulling the backing paper of the label tape to separate the label from the peeling plate and eject it. The Z-axis cylinder is responsible for driving the entire labeling module to move up and down, realizing the action of the labeling head approaching and leaving the fabric.

[0004] Therefore, the existing technology still has at least the following shortcomings in actual use, which are the problems that this invention aims to solve: 1. It includes at least two driving components, one for label tape conveying and the other for up and down Z-axis direction, resulting in a large total weight of the machine head; 2. The dual drive has a synchronization delay, causing problems such as label ejection position deviation, label not sticking firmly, or label wrinkling.

[0005] In conclusion, it is necessary to develop a cutting bed labeling device with a simple drive structure and reliable synchronization to solve this problem. Summary of the Invention

[0006] This invention provides a rolling labeling device, including a base mounting plate, a linear guide rail, a support platform, a drive linkage unit, a label tape path unit, a peeling plate, a traction shaft, a transmission unit, and a label dispensing adjustment unit. Utilizing the power of the Z-axis movement of the cutting machine head, the label is synchronously driven to feed through mechanical transmission, eliminating the need for an additional independent motor. This invention effectively reduces the overall weight of the cutting machine head, eliminates synchronization delays between multiple drives, simplifies the equipment structure, and lowers production and maintenance costs.

[0007] This invention overcomes the shortcomings of existing technologies and provides a rolling labeling device, installed on a cutting machine head, including a base mounting plate on the cutting machine head, a linear guide rail vertically mounted on the base mounting plate, a support platform slidably mounted on the linear guide rail, a drive linkage unit mounted on the base mounting plate and connected to the support platform to drive the support platform to slide up and down, a label tape path unit mounted on the outer plate of the support platform, and a peeling plate located at the lower end of the outer plate of the support platform and directly below the label tape path unit for peeling the label off the label tape, and a device disposed inside the support platform. A traction shaft extending from the outer side plate of the support platform for driving the label belt transmission is provided between the base mounting plate and the support platform, and a transmission unit is provided to convert the downward sliding of the support platform into the driving force of the traction shaft; the transmission unit includes a linear rack provided on the base mounting plate and parallel to the linear guide rail, a main gear provided on the side plate of the support platform near the base mounting plate and meshing with the linear rack, a one-way bearing provided in the inner hole of the main gear, and a horizontal transition shaft provided in the one-way bearing, with its end horizontally inserted into the interior of the support platform and connected to the traction shaft.

[0008] A further preferred technical solution is that the label tape path unit includes a label feeding roll, a take-up roll, a guide transition roller, and a driven pressing roller, which are horizontally arranged on the outer side plate of the support platform. The driven pressing roller is fitted to the traction shaft.

[0009] A further preferred technical solution is that the drive linkage unit includes a linkage A with its upper end hinged to the base mounting plate, a linkage B with its lower end hinged to the upper end of the support platform, and a cylinder with its tail end mounted on the base mounting plate via a hinge seat and located in the middle of the connection between the linkage A and the linkage B. The push rod end of the cylinder, the lower end of the linkage A, and the upper end of the linkage B are hinged together to form an elbow joint.

[0010] A further preferred technical solution includes a bid adjustment unit, comprising a first bevel gear disposed on the inner end of the horizontal transition shaft located on the support platform, a vertical transition shaft disposed vertically inside the support platform and having its lower end meshing with the first bevel gear via a second bevel gear, a cantilever plate disposed on the inner side wall of the support platform and extending horizontally towards the center through a bearing for the vertical transition shaft to pass through, an active friction plate horizontally disposed on the upper end of the vertical transition shaft, and a spline disposed on the surface of the traction shaft located on the inner section of the support platform. A spline sleeve is provided on the spline; a driven roller is pressed onto the side end of the spline sleeve and pressed against the surface of the active friction plate; an annular groove is provided on the end of the traction shaft away from the driven roller; a dial seat is inserted into the annular groove by a bearing; an adjusting screw is provided in the support platform, parallel to the traction shaft, and threaded through the dial seat; a guide shaft is provided in the support platform, parallel to the traction shaft, and passes through the dial seat; and a scale wheel is provided on the outer end of the adjusting screw extending out of the side plate of the support platform.

[0011] A further preferred technical solution is that the transmission unit further includes a housing disposed in the inner hole of the one-way bearing, and a torsion spring disposed between the housing and the horizontal transition shaft.

[0012] A further preferred technical solution includes a pressure roller disposed at the bottom end of the outer side plate of the support platform and located on the side of the peeling plate, the pressure roller being slightly lower than the peeling plate.

[0013] A further preferred technical solution is that the connecting rod A and the connecting rod B form a vertical straight line.

[0014] A further preferred technical solution is that the lower end of the peeling plate has an acute-angled cutting edge.

[0015] The beneficial effects of this invention are at least as follows: 1. By using only a single drive component and leveraging the mechanical power of Z-axis motion to drive the label conveying, the overall weight of the labeling device is reduced compared to traditional solutions, directly improving the dynamic performance of the cutting bed; 2. It fundamentally eliminates the problem of synchronous delay in dual drives, significantly improving the consistency of label dispensing length and the accuracy of labeling position; 3. It achieves a rigid locking function. When the cylinder is pushed to a certain position, the linkage structure allows linkage A and linkage B to form a vertical straight line reaching the mechanical dead point, rigidly locking the support platform. This prevents bouncing due to uneven fabric or pressure instability due to air pressure fluctuations, ensuring reliable adhesion between the label and the fabric; 4. It achieves stepless adjustment of the label dispensing length. Through the friction plate and screw mechanism of the label dispensing adjustment unit, the operator can continuously adjust the label dispensing length within a wide range simply by rotating the scale wheel, without adjusting electrical parameters or replacing transmission parts.

[0021] Example 1 As attached Figures 1-7 As shown, a rolling labeling device is installed on a cutting machine head a, including a base mounting plate 1 on the cutting machine head a, a linear guide rail 2 vertically mounted on the base mounting plate 1, a support platform 3 slidably mounted on the linear guide rail 2, a drive linkage unit 4 mounted on the base mounting plate 1 and connected to the support platform 3 to drive the support platform 3 to slide up and down, a label tape path unit 5 mounted on the outer plate of the support platform 3, a peeling plate 6 located at the lower end of the outer plate of the support platform 3 and directly below the label tape path unit 5 for peeling the label from the label tape b, a traction shaft 7 located inside the support platform 3 and extending one end out of the outer plate of the support platform 3 for driving the label tape b, and a drive shaft 7 located between the base mounting plate 1 and the support platform 3. The transmission unit 8 converts the downward sliding of the support platform 3 into the driving force of the traction shaft 7. The transmission unit 8 includes a linear rack 81 disposed on the base mounting plate 1 and parallel to the linear guide rail 2, a main gear 82 disposed on the side plate of the support platform 3 near the base mounting plate 1 and meshing with the linear rack 81, a one-way bearing 83 disposed in the inner hole of the main gear 82, and a horizontal transition shaft 84 disposed in the one-way bearing 83, with its end horizontally inserted into the interior of the support platform 3 and connected to the traction shaft 7. The label tape path unit 5 includes a label feeding roll 51, a take-up shaft 52, a guide transition roller 53, and a driven pressing rubber roller 54 disposed horizontally on the outer side plate of the support platform 3. The driven pressing rubber roller 54 is fitted to the traction shaft 7.

[0022] In this embodiment, a rolling labeling device is provided. The device is installed on the side of the head of a CNC cutting machine and is used to automatically apply labels to multi-layer fabrics. The overall structure includes the following main parts: a base mounting plate, a linear guide rail, a support platform, a drive linkage unit, a label tape path unit, a peeling plate, a traction shaft, a transmission unit, and a pressure roller, which will be described one by one below.

[0023] An aluminum alloy plate serves as the base mounting plate, vertically fixed to the side plate of the machine head using bolts. During installation, ensure the surface of the base mounting plate is perpendicular to the cutting table surface. Its shape is designed to fit the spatial shape of the cutting machine head side plate, typically rectangular or L-shaped. Standard miniature ball bearing linear guides are selected as the linear guides, with two guides arranged parallel to each other and a certain gap reserved in the middle for mounting the transmission unit. The support platform has a box-shaped structure, with multiple protrusions on the inner side plate surface near the linear guides, which slide on the linear guides. The support platform is the moving part of the entire labeling device, with the label tape path unit, peeling plate, pressure rollers, and other components mounted on its front. Internally... Equipped with a transmission unit and a label dispensing adjustment unit, it supports almost all parts except for the base mounting plate. The traction shaft is an alloy steel shaft, mounted inside the support platform via two deep groove ball bearings, with one end extending out of the outer side plate of the support platform. The surface of the extended part of the traction shaft is knurled to increase friction with the backing paper. The peeling plate is located at the lower end of the outer side plate of the support platform and directly below the label tape path unit. It is a stainless steel plate with a thickness of 1 to 2 millimeters. After the label tape passes through the label tape path unit, it reaches the lower end of the peeling plate, where the backing paper folds back 180 degrees. Due to its own rigidity, the label separates from the backing paper and is ejected.

[0024] The label tape path unit includes a label feeding reel, a take-up shaft, a guide transition roller, and a driven pressure roller, all horizontally mounted on the outer side plate of the support platform. The label feeding reel is mounted at the top of the outer side plate of the support platform, supported by a bearing seat, and has a friction damper installed at one end. The friction damper includes a fixed friction plate, a movable friction plate, and an adjusting nut. Rotating the adjusting nut changes the clamping force between the friction plates, thereby adjusting the label feeding resistance. The adjustment standard for the damping torque is: when the label tape is lightly pulled by hand, there should be appropriate resistance, but not too great; when the traction shaft stops rotating, the label... The tape will not continue to unwind; the recycling shaft is installed on the side of the label supply roll and in the upper middle part of the outer side plate of the support platform. It is connected to the support platform through a spring-loaded quick-release structure. The operator can remove the recycling shaft by pressing the pin, put on the recycling paper tube, and then re-insert it; at least two guide transition rollers are provided, both installed in the area below the label supply roll and above the peeling plate. They are made of aluminum alloy and have miniature deep groove ball bearings at both ends; the driven clamping rubber roller is attached to the position corresponding to the protruding part of the traction shaft, and its surface is covered with a layer of nitrile rubber for clamping the bottom paper in cooperation with the traction shaft.

[0025] The transmission unit is disposed between the base mounting plate and the support platform, and is used to convert the downward sliding of the support platform into the driving force of the traction shaft. The linear rack is a standard spur rack with a module of approximately 1 to 1.5 mm and a length equal to the stroke of the support platform plus a 50 mm allowance. It is disposed on the base mounting plate and parallel to the linear guide rail. The main gear is a standard spur gear with the same module as the linear rack. It is mounted on the outer surface of the inner side plate of the support platform via a bearing, and its installation position ensures correct meshing with the linear rack, with a meshing clearance of approximately 0.05 to 0.15 mm. The one-way bearing is disposed in the inner hole of the main gear. The one-way bearing is a special type of bearing. The inner and outer rings are allowed to rotate relative to each other in one direction (free-spinning), while locking together in the other direction for synchronized rotation. In this invention, the installation direction of the one-way bearing is set as follows: when the support platform moves downward, the one-way bearing locks, and the rotation of the main gear is transmitted through the one-way bearing; when the support platform moves upward, the one-way bearing free-spins, and the reverse rotation of the main gear is not transmitted to the subsequent transmission chain; the horizontal transition shaft is disposed within the one-way bearing, with its end horizontally inserted into the interior of the support platform and directly connected to the traction shaft. It is worth noting that in practical applications, the cylinder can be a Z-axis cylinder used to drive the machine head up and down, enabling labeling to be completed simultaneously with cutting.

[0026] The operation method of this embodiment is as follows: S1. Install the label roll, pull out the front end of the label tape, and thread the tape along the following path: sequentially around the side of the first guide transition roller, the side of the second guide transition roller, the bottom end of the peeling plate, then through the gap between the traction shaft and the driven pressing roller, and finally wrap the front end of the backing paper around the paper tube of the recycling shaft about two turns. After threading, gently pull the label tape by hand; you should feel appropriate tension, and the movement should be smooth without jamming. S2. Adjust the label feeding damping. Rotate the adjusting nut on the label feeding roll by hand to adjust the clamping force of the friction damper. The standard is that when you release your hand, the label... S3. Adjust the air pressure of the cylinder on the air source regulating valve of the cutting bed; S4. Start labeling, the cylinder extends and retracts, the support platform descends along the linear guide rail, the linear rack drives the main gear to rotate, the one-way bearing is locked, the power is transmitted to the traction shaft through the horizontal transition shaft, the traction shaft cooperates with the driven pressing rubber roller to pull the backing paper, the label separates from the bottom end of the peeling plate and is ejected; S5. After a single labeling is completed, the cylinder retracts, the support platform is raised, the one-way bearing rotates freely, the traction shaft does not rotate, the backing paper does not retract, and continues to wait for the next cut piece to be labeled.

[0027] In a preferred embodiment, the drive linkage unit 4 includes a linkage A41 with its upper end hinged to the base mounting plate 1, a linkage B42 with its lower end hinged to the upper end of the support platform 3, and a cylinder 43 with its tail end mounted on the base mounting plate 1 via a hinge seat and located at the middle of the connection between the linkage A41 and the linkage B42. The push rod end of the cylinder 43, the lower end of the linkage A41, and the upper end of the linkage B42 are hinged together to form an elbow joint.

[0028] In this embodiment, two hinge seats are welded to the upper part of the base mounting plate for mounting the upper end of the connecting rod A and the tail end of the cylinder. The connecting rod A is an aluminum alloy connecting rod with pin holes machined at both ends. The upper end is hinged to the hinge seat on the upper part of the base mounting plate by a pin shaft. The pin shaft is fitted with a clearance fit, allowing the connecting rod A to rotate flexibly around the pin shaft. The connecting rod B is also an aluminum alloy connecting rod with the same cross-section as the connecting rod A. The lower end is hinged to the hinge seat on the upper end of the support platform by a pin shaft. The lower end of the connecting rod A and the upper end of the connecting rod B are hinged together by a common pin shaft, which is also the connection point of the cylinder push rod end. The three parts (the lower end of the connecting rod A, the upper end of the connecting rod B, and the end of the cylinder push rod) are hinged together by the same pin shaft to form an elbow joint. The cylinder is a thin cylinder with a built-in magnetic ring for position detection. It is horizontally mounted on the upper part of the base mounting plate and can swing around the hinge point in the vertical plane.

[0029] In a preferred embodiment, the connecting rod A41 and the connecting rod B42 form a vertical straight line.

[0030] In this embodiment, when the cylinder is retracted / extended (active state), connecting rod A and connecting rod B are at an angle, and the support platform is in a higher position (e.g., Figure 5 and Figure 7 As shown); when the cylinder extends / retracts, the push rod pushes the hinge center of the elbow joint forward / backward, the connecting rods A and B are gradually spread apart, and the support platform moves downward along the linear guide rail; when the cylinder push rod is fully extended (locked state), the connecting rods A and B form a vertical straight line, the mechanism reaches the mechanical dead point position, and the support platform is locked in the lowest position (as shown). Figure 4 and Figure 6 As shown in the figure, at this time, the upward reaction force from the fabric cannot push the cylinder backward, thus achieving rigid locking.

[0031] As a preferred embodiment, the transmission unit 8 further includes a housing 85 disposed in the inner hole of the one-way bearing 83, and a torsion spring 86 disposed between the housing 85 and the horizontal transition shaft 84.

[0032] In this embodiment, the outer casing is disposed within the inner bore of the one-way bearing. The outer casing is a cylindrical aluminum alloy or steel part, with its outer diameter interference-fitted with the inner bore of the one-way bearing. The torsion spring is disposed between the outer casing and the horizontal transition shaft. Specifically, the torsion spring is a spring-loaded torsion spring (also known as a spiral spring), with its outer end fixed to the inner wall of the outer casing and its inner end fixed to the horizontal transition shaft. During installation, a certain preload should be applied to the torsion spring before fixing both ends. When the support platform moves downward and the one-way bearing locks, the outer casing rotates with the main gear, driving the horizontal transition shaft to rotate via the torsion spring. This effectively buffers transmission shocks, making power output more stable, and provides some protection during sudden load changes.

[0033] As a preferred embodiment, it further includes a pressure roller 10 disposed at the bottom end of the outer side plate of the support platform 3 and located on the side of the peeling plate 6, the pressure roller 10 being slightly lower than the peeling plate 6.

[0034] In this embodiment, the pressure roller is positioned to the side of the peeling plate to compact the label that has been peeled off onto the fabric surface. The roller is positioned slightly lower than the peeling plate to ensure that the peeling plate will never come into direct contact with the fabric surface, thus preventing damage to the fabric due to device failure.

[0035] As a preferred embodiment, the lower end of the peeling plate 6 has an acute-angled cutting edge.

[0036] In this embodiment, the peeling plate is approximately triangular or trapezoidal in shape, with the bottom end machined into an acute-angled cutting edge. The cutting edge angle is approximately 15 to 25 degrees, preferably 20 degrees, and the acute-angled cutting edge must be smooth and burr-free.

[0037] Example 2 As attached Figures 8-9As shown, as a further improvement to the above embodiment, it also includes a bid adjustment unit 9. The bid adjustment unit 9 includes a first bevel gear 91 disposed on the inner end of the horizontal transition shaft 84 located on the support platform 3; a vertical transition shaft 93 vertically disposed inside the support platform 3 and meshing with the first bevel gear 91 at its lower end via a second bevel gear 92; a cantilever plate 94 disposed on the inner wall of the support platform 3 and extending horizontally towards the center through a bearing for the vertical transition shaft 93 to pass through; an active friction plate 95 horizontally disposed on the upper end of the vertical transition shaft 93; a spline 96 disposed on the surface of the traction shaft 7 located on the inner section of the support platform 3; and a... A spline sleeve 97 on the spline 96, a driven roller 98 pressed onto the side end of the spline sleeve 97 and pressed against the surface of the active friction plate 95, an annular groove 99 provided on the end of the traction shaft 7 away from the driven roller 98, a dial seat 910 inserted into the annular groove 99 by a bearing, an adjusting screw 911 provided in the support platform 3, parallel to the traction shaft 7 and threaded through the dial seat 910, a guide shaft 912 provided in the support platform 3, parallel to the traction shaft 7 and passing through the dial seat 910, and a scale wheel 913 provided on the outer end of the adjusting screw 911 extending out of the side plate of the support platform 3.

[0038] In this embodiment, the first bevel gear is disposed on the end of the horizontal transition shaft located inside the support platform, meshing with the first bevel gear, and is installed at the lower end of the vertical transition shaft. The vertical transition shaft is vertically disposed inside the support platform and is mounted by two bearings, allowing it to rotate only around its own axis. The shaft angle between the first bevel gear and the second bevel gear is 90 degrees, used to convert the horizontal rotation of the horizontal transition shaft into the vertical rotation of the vertical transition shaft. The cantilever plate is disposed on the inner side wall of the support platform, and mounting holes are machined on its horizontal surface. Bearings are installed in the holes, and the vertical transition shaft passes through the bearings, with intermediate support provided by the cantilever plate. The active friction disc is disc-shaped and is horizontally disposed on the vertical transition shaft. The upper surface of the horizontal transition shaft undergoes special treatment to improve the coefficient of friction, such as machining a fine mesh pattern, spraying a friction coating, or attaching a wear-resistant rubber sheet. The spline sleeve is mounted on the spline, and the inner hole of the spline sleeve is machined with a spline groove that mates with the spline, allowing the spline sleeve to transmit torque while sliding axially on the traction shaft. The driven roller is pressed onto the side end of the spline sleeve and onto the upper surface of the active friction plate. When the active friction plate rotates, it drives the driven roller to rotate through friction. The driven roller drives the traction shaft to rotate through the engagement of the spline sleeve and the spline. The overall cooperation of these components allows the horizontal transition shaft to still drive the traction shaft in different positions.

[0039] The following components are the main components for adjusting the single label feeding volume: The annular groove is located on the end of the traction shaft away from the driven roller; the dial ring seat is an annular metal part with a double-row angular contact ball bearing installed inside; the inner ring of the bearing is engaged in the annular groove, so that the dial ring seat is axially fixed to the traction shaft but can rotate relative to it; the two ends of the adjusting screw are mounted on the support platform through bearing seats, with one end extending out of the outer side plate of the support platform and equipped with a scale wheel to avoid interference with the label tape path unit; the scale wheel is a metal handwheel with scale lines engraved on its outer circumference, each scale corresponding to a change in label feeding length; the guide optical shaft is a precision linear optical shaft, with both ends fixed inside the support platform; the dial ring seat has through holes machined to mate with the guide optical shaft, providing guidance for the movement of the dial ring seat.

[0040] The working principle of this embodiment is as follows: When the operator rotates the scale wheel, the adjusting screw rotates, pushing the dial seat to move along the guide optical axis. The dial seat drives the spline sleeve to slide axially on the traction shaft through the bearing, thereby changing the contact radius of the driven roller on the active friction plate. After the contact radius changes, the transmission ratio changes accordingly, realizing stepless adjustment of the billing length.

[0041] The cylinders, linear guides, bearings, etc. mentioned above are common knowledge known to those skilled in the art, and will not be described in detail in this application.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the present invention.
