Description

Automatic labeling system for spools Technical Field

[0001] This utility model relates to the field of labeling technology, specifically to an automatic labeling system for reels. Background Technology

[0002] The labels on finished enameled wire products display information such as wire gauge, weight, barcode, and batch number. Labeling finished wire spools facilitates product identification, quality control, and inventory management, making it an essential step in enameled wire production.

[0003] However, the traditional method involves manually affixing labels. This means first printing labels with a label printer, then having operators manually affix the labels to the online storage tray, followed by scanning, recognition, and information entry into the system using a handheld scanner. While this achieves the goal of labeling the online storage tray, it has the following problems:

[0004] 1. Labels are prone to mismatch with the reel: Manual operation can easily lead to labels being placed on the wrong reel, resulting in inaccurate data entry, affecting the traceability of production information, and potentially causing errors in subsequent production processes, which can easily lead to product quality problems;

[0005] 2. Low production efficiency: It takes a certain amount of time to fill the spool with enameled wire. The long waiting time for workers leads to a waste of human resources and a decrease in production efficiency.

[0006] 3. Poor label pasting quality: Manual operation is prone to problems such as skewed or uneven label pasting, which makes it difficult for the scanner to accurately identify and enter information, affecting the smooth progress of subsequent processes and potentially causing the enameling machine to stop or be reworked. Summary of the Invention

[0007] To address the aforementioned shortcomings, the purpose of this utility model is to provide an automatic labeling system for spools with a reasonable structural design and good labeling effect.

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] An automatic labeling system using a spool includes a scanner, a label printer, a robotic arm, a frame, a forward / backward mechanism, a crossbar, a label suction device, and a spool clamp. The label printer is mounted on the frame. The forward / backward mechanism is mounted on the frame at a side position corresponding to the label printer. The crossbar is mounted on the forward / backward mechanism and extends at one end to the label outlet of the label printer. The label suction device is mounted on the crossbar. The scanner is mounted on the crossbar at a side position corresponding to the label suction device. The spool clamp is mounted on the robotic arm, which is located on one side of the frame and can grasp and move the label to the workstations of the label suction device and the scanner using the spool clamp.

[0010] As a preferred embodiment of this utility model, the spool clamp includes a mounting base, a mounting frame, an opening and closing device, a sliding shaft, a sliding block, a spool hole insertion shaft, and clamping arms. The mounting base is disposed on the mounting frame, and the spool hole insertion shaft is vertically disposed on the bottom surface of the mounting frame. The spool hole insertion shaft has two receiving grooves on its opposite outer walls. The sliding shaft is horizontally disposed on the mounting frame, and the two sliding blocks are movably disposed on the sliding shaft. The two clamping arms are located in the two receiving grooves respectively, and the upper ends of the two clamping arms are connected to their corresponding sliding blocks, and the lower ends are provided with hook feet. The opening and closing device is disposed on the mounting frame and can drive the two sliding blocks to open and close relative to each other, so that the two clamping arms extend or retract from the receiving grooves. When the clamping arms retract, their volume shrinks so that they can be inserted into the spool hole of the spool. When the clamping arms extend, their volume expands so that they can abut against the spool hole of the spool, thereby achieving the purpose of locking.

[0011] As a preferred embodiment of this utility model, it further includes a pressure plate assembly, which includes a pressure plate cylinder and a pressure ring. The two pressure plate cylinders are symmetrically arranged on both sides of the mounting frame. The pressure ring is located below the mounting frame and is fixed on the piston rods of the two pressure plate cylinders. The disc hole insertion shaft passes through the annular hole of the pressure ring. When the reel is moved, the pressure ring presses on the reel to prevent shaking and ensures good stability.

[0012] As a preferred embodiment of this utility model, the two storage slots are connected, which is easy to process.

[0013] As a preferred embodiment of this utility model, the opening and closing device is an opening and closing cylinder, which has a simple structure and is easy to implement.

[0014] As a preferred embodiment of this utility model, the forward and backward mechanism includes a forward and backward cylinder, a forward and backward slide rail, a forward and backward slider, and a support. The forward and backward slide rail is disposed on the frame, the forward and backward slider is movably disposed on the forward and backward slide rail, the support is disposed on the forward and backward slider, the forward and backward cylinder is disposed on the frame, and the piston rod is connected to the support, and the crossbar is disposed on the support.

[0015] As a preferred embodiment of this utility model, the label adsorption device includes a fixed base, a vacuum suction base, an elastic component, an optical fiber sensor, and a proximity switch. The upper end of the elastic component is connected to the fixed base, and the lower end is connected to the vacuum suction base. The optical fiber sensor is located on the vacuum suction base, and the proximity switch is disposed on the fixed base and faces the vacuum suction base.

[0016] As a preferred embodiment of this utility model, the lower surface of the vacuum suction base is provided with a rubber pad and a sponge stacked in sequence, which has a buffering and adsorption effect.

[0017] As a preferred embodiment of this utility model, an air blowing pipe is provided below the label outlet position. Several air outlets are arranged along the axial direction of the air blowing pipe. The air outlets face the front of the label outlet and can blow out gas to support the label, which is more conducive to the adsorption of the vacuum suction seat.

[0018] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design. The wire reel clamp is mounted on a robotic arm, which grips the fully wound wire reel. A label printer prints a label, which is then adsorbed by a label adsorption device. A forward / backward mechanism pushes the label adsorption device to a predetermined position. Next, the robotic arm moves the wire reel to a position below the label adsorption device and lifts it upwards, affixing the label to the top surface of the wire reel. Then, the robotic arm moves the labeled wire reel to a scanner for scanning and input into the system. Finally, it moves it to the finished product area. This automatically completes the processes of label printing, label affixing, and scanning, making the operation simple and convenient. It improves production efficiency, reduces the labor intensity of operators, increases production revenue, avoids mislabeling, and ensures good adhesion.

[0026] Referring to Figures 1 to 6, this embodiment provides an automatic labeling system for spools, which includes a frame 1, a scanner 2, a label printer 3, a robotic arm 4, a forward / backward mechanism 5, a crossbar 6, a label adsorption device 7, and a spool clamp 8. In this embodiment, a KUKA KR210R2700 palletizing robotic arm with six degrees of freedom is selected. In other embodiments, six-axis robotic arms from other brands can also be used.

[0027] The label printer 3 is mounted on the frame 1. The forward / backward mechanism 5 is mounted on the frame 1 at a position corresponding to the side of the label printer 3. The forward / backward mechanism 5 includes a forward / backward cylinder 51, a forward / backward slide rail 52, a forward / backward slider 53, and a support 54. The forward / backward slide rail 52 is mounted on the frame 1. The forward / backward slider 53 is movably mounted on the forward / backward slide rail 52. The support 54 is mounted on the forward / backward slider 53. The forward / backward cylinder 51 is mounted on the frame 1, and its piston rod is connected to the support 54. The crossbar 6 is mounted on the support 54 of the forward / backward mechanism 5, and one end extends to the label outlet of the label printer 3.

[0028] The label adsorption device 7 is positioned on the crossbeam 6 corresponding to the label outlet position of the label printer 3, to facilitate the adsorption of printed labels. Preferably, an air blowing pipe 9 is provided below the label outlet position, with several air outlets arranged axially on the air blowing pipe 9. These air outlets face forward of the label outlet, allowing air to be blown out to support the label, further facilitating the adsorption by the label adsorption device 7.

[0029] The label adsorption device 7 includes a fixed base 71, a vacuum suction base 72, an elastic component 73, a fiber optic sensor 74, and a proximity switch 75. The upper end of the elastic component 73 is connected to the fixed base 71, and the lower end is connected to the vacuum suction base 72. The elastic component 73 is preferably a spring. The fiber optic sensor 74 is located on the vacuum suction base 72 and extends to the bottom surface of the vacuum suction base 72. It is used to sense whether a label is adsorbed on the bottom surface of the vacuum suction base 72. The proximity switch 75 is set on the fixed base 71 and faces the vacuum suction base 72. It is used to sense the height to which the vacuum suction base 72 rises and compresses the elastic component 73, ensuring sufficient elastic force to press the label firmly and adhere it securely.

[0030] Preferably, a rubber pad and a sponge are stacked sequentially on the lower surface of the vacuum suction base 72. The surface is flat and soft, and the vacuum suction base 72 can tightly adhere to the label through the vacuum suction hole, ensuring that the pasting process is flat and firm, and avoiding falling off or tilting.

[0031] The scanner 2 is positioned on the crossbar 6 on one side corresponding to the label adsorption device 7, so as to facilitate scanning and inputting the label into the system after it is pasted.

[0032] The wire reel clamp 8 is mounted on the robotic arm 4, which is located on one side of the frame 1 and can be moved to the workstations of the label adsorption device 7 and the scanner 2 by means of the wire reel clamp 8.

[0033] Specifically, the coil clamp 8 includes a mounting base 81, a mounting frame 82, an opening and closing device 83, a sliding shaft 84, a sliding block 85, a coil hole insertion shaft 86, and a clamping arm 87. The mounting base 81 is disposed on the mounting frame 82, and the mounting base 81 is installed with the robot arm 4.

[0034] The disc-hole insert shaft 86 is vertically mounted on the bottom surface of the mounting frame 82. Two receiving grooves 861 are provided on the opposite outer walls of the disc-hole insert shaft 86. For ease of processing, the two receiving grooves 861 are connected to form an integral slotted structure. The sliding shaft 84 is horizontally mounted on the mounting frame 82. Two sliding blocks 85 are movably mounted on the sliding shaft 84. Two clamping arms 87 are correspondingly located within the two receiving grooves 861, with the upper ends of the two clamping arms 87 connected to their corresponding sliding blocks 85, and the lower ends provided with hook feet 871. Multiple hook feet 871 can be provided, increasing in a stepped manner to meet the gripping requirements of coils with different disc hole sizes. The opening and closing device 83 is an opening and closing cylinder, with a simple structure and easy implementation. The opening and closing device 83 is mounted on the mounting bracket 82 and can drive the two slides 85 to open and close relative to each other, so that the two clamping arms 87 extend or retract from the storage slot 861. When the two clamping arms 87 retract, the volume is reduced so that they can be inserted into the disc hole of the spool 10. When the two clamping arms 87 extend relative to each other, the volume is expanded so that the hook foot 871 can be hooked into the inner edge of the disc hole of the spool 10. To improve the stability of the wire reel during handling, a pressure plate assembly can be provided on the wire reel clamp 8. Specifically, the pressure plate assembly includes a pressure plate cylinder 88 and a pressure ring 89. The two pressure plate cylinders 88 are symmetrically arranged on both sides of the mounting frame 82. The pressure ring 89 is located below the mounting frame 82 and is fixed to the piston rods of the two pressure plate cylinders 88. The disc hole insertion shaft 86 passes through the annular hole of the pressure ring 89. When the wire reel 10 is moved, it cooperates with the hook feet 871 of the two clamping arms 87 to hook onto the disc hole of the wire reel 10, while the pressure ring 89 presses on the wire reel 10, effectively clamping and positioning the wire reel 10 from top to bottom, preventing shaking, and ensuring good handling stability.

[0035] During operation, the automatic winding machine winds the wire spool. After the wire spool is wound, it sends the label information such as wire gauge, weight, barcode, and batch number of the wire spool to the label printer 3.

[0036] After receiving the label signal, the label printer 3 starts printing and sending out the label. The air blowing solenoid valve is energized to connect the positive pressure air source, and the air blowing pipe 9 blows out the gas to support the label and stick it tightly to the bottom surface of the vacuum suction seat 72.

[0037] The fiber optic sensor 74 detects the tag and sends a feedback detection signal to the PLC controller. The PLC controller then controls the vacuum generator to power on and connect the negative pressure air source. The vacuum suction holder 72 begins to draw air, adsorbing the tag onto the vacuum suction holder 72.

[0038] The PLC controller starts a countdown, such as three seconds. When the time is up, the solenoid valve for blowing air is de-energized, and the blowing pipe 9 stops blowing air.

[0039] The PLC controller energizes the forward and backward solenoid valve, and the forward and backward cylinder 51 pushes out the crossbar 6, sending the label adsorption device 7 to the predetermined label pasting position.

[0040] The robotic arm 4 uses the wire spool clamp 8 to grab the wire spool 10 that is already fully wound and move it to a position below the predetermined label pasting position.

[0041] The robotic arm 4 lifts the coil 10 upwards until it is in close contact with the bottom surface of the vacuum suction holder 72, and continues to compress the elastic component 73 upwards until the proximity switch 75 senses that the vacuum suction holder 72 has risen to the predetermined height, ensuring that the label is tightly attached to the coil 10. At this time, the vacuum generator is de-energized and the vacuum suction holder 72 stops sucking air.

[0042] Robotic arm 4 moves the labeled wire reel 10 to the scanner 2 for scanning and input into the system. Finally, it moves the reel to the finished product area to stack it. Robotic arm 4 then returns to its initial position to wait for the next round of operation.

[0043] The forward and backward cylinder 51 drives the crossbeam 6 to retract, resetting the label adsorption device 7 to its initial position, completing one full cycle, and waiting for the next labeling signal.

[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
