Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, specifically a relay-type labeling mechanism. Background Technology

[0002] In the field of product packaging and labeling, tax labeling machines are key equipment for automating tax label application, and the performance of the label picking and labeling mechanism directly determines the operating speed and stability of the tax labeling machine. Currently, most tax labeling machines on the market use a linear relay mechanism that integrates label picking and labeling. This type of mechanism has significant drawbacks: firstly, the linear motion trajectory leads to low efficiency in the connection between label picking, transfer, and labeling actions, resulting in slow overall equipment speed and difficulty in meeting the high-efficiency operation requirements of large-scale production scenarios; secondly, the label positioning accuracy during the linear relay process is easily affected by the mechanism's motion errors, leading to frequent problems such as unstable label picking and label offset. This not only reduces the product labeling qualification rate but also causes double waste of labels and products, increasing production costs for enterprises and hindering the improvement of overall social production efficiency. Therefore, those skilled in the art provide a relay-type label picking and labeling mechanism to solve the problems mentioned in the background art. Summary of the Invention

[0003] The purpose of this invention is to provide a relay-type labeling mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A relay-type labeling and applicating mechanism includes a labeling frame. A label slot adjustment seat is mounted on the upper end of the labeling frame, and a label slot is mounted on the label slot adjustment seat. A turntable is mounted on the front end of the labeling frame. A second suction nozzle is mounted on the upper end of the turntable, and a third suction nozzle is mounted on the lower end. A rotating shaft is positioned above the turntable, and a first suction nozzle is mounted on the end of the rotating shaft. A glue spray head adjustment bracket is mounted on one side of the turntable, and a glue spray gun is mounted on the glue spray head adjustment bracket. A label suction detection photoelectric sensor is located on one side of the glue spray head adjustment bracket.

[0005] The first suction nozzle is made of food-grade soft silicone, while the second and third suction nozzles are both made of metal.

[0006] As a further embodiment of this utility model: one end of the rotating shaft is connected to a stepper motor via a coupling, and the stepper motor controls the rotating shaft to rotate 180° clockwise and then 180° counterclockwise to reset.

[0007] As a further improvement of this utility model: the turntable is a circular metal disc structure, the middle part of which is connected to a servo motor through a bearing, and the servo motor controls the turntable to rotate continuously counterclockwise at a constant speed.

[0008] As a further embodiment of this utility model: the second suction nozzle and the third suction nozzle are symmetrically installed on the edge of the turntable, and the center connecting line of the second suction nozzle and the third suction nozzle passes through the center of the turntable, and the adsorption surface of the two nozzles is parallel to the cross-section of the turntable.

[0009] As a further improvement of this utility model: the glue gun is mounted on one side of the turntable via a glue head adjustment bracket. The glue head adjustment bracket includes a horizontal adjustment slider and a vertical adjustment rod, which controls the glue gun to make fine adjustments in the horizontal and vertical directions so that the glue nozzle can be aligned with the preset glue spraying area of ​​the label on the second or third suction nozzle.

[0010] As a further improvement of this utility model: the glue gun is connected to an external glue supply system, and its control end is connected to the signal output end of the label detection photoelectric sensor via a wire. The glue gun will only start spraying glue according to the preset glue amount and spraying time when the label detection photoelectric sensor detects that the second or third suction nozzle has a label adsorbed.

[0011] As a further improvement of this utility model: the label groove is a U-shaped groove structure, the width and depth of the groove can be adapted according to the specifications of the label, and the bottom of the label groove is provided with an anti-slip pad.

[0012] As a further improvement of this utility model: the bottom of the label slot adjustment seat is provided with a slide rail, which slides along the horizontal direction of the labeling machine frame.

[0013] As a further improvement of this utility model: the label detection photoelectric sensor is a diffuse reflection photoelectric sensor, and the label detection photoelectric sensor is mounted on one side of the turntable by a bracket, with the detection end facing the movement trajectory of the second or third suction nozzle. When the second or third suction nozzle carries the label through the detection area, the label detection photoelectric sensor receives the reflected signal and outputs a high level, triggering the glue gun to spray glue; if no label is detected, it outputs a low level, and the glue gun does not operate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: During operation, the first suction nozzle uses a soft rubber nozzle, greatly reducing the failure rate of ticket collection. The second and third suction nozzles alternately collect and apply labels simultaneously, saving time and improving efficiency. After collecting the label, the machine rotates while checking whether the second and third suction nozzles have collected the label, ensuring that glue is only applied when a label is present, reducing product waste caused by unstable label collection. This significantly improves the overall efficiency and pass rate of the machine, greatly reduces customer operating costs, and enhances social production efficiency. Attached Figure Description

[0017] Please see Figure 1 In this embodiment of the present invention, a relay-type labeling and applicating mechanism includes a labeling frame 11. A label slot adjustment seat 9 is installed at the upper end of the labeling frame 11, and a label slot 8 is installed on the label slot adjustment seat 9. A turntable 4 is installed at the front end of the labeling frame 11. A second suction nozzle 2 is installed at the upper end of the turntable 4, and a third suction nozzle 3 is installed at the lower end. A rotating shaft 10 is provided above the turntable 4, and a first suction nozzle 1 is installed at the end of the rotating shaft 10. A glue spray head adjustment bracket 6 is installed on one side of the turntable 4, and a glue spray gun 5 is installed on the glue spray head adjustment bracket 6. A label suction detection photoelectric sensor 7 is provided on one side of the glue spray head adjustment bracket 6.

[0018] The first suction nozzle 1 is made of food-grade soft silicone, while the second suction nozzle 2 and the third suction nozzle 3 are both made of metal.

[0019] One end of the rotating shaft 10 is connected to the stepper motor via a coupling. The stepper motor controls the rotating shaft 10 to rotate 180° clockwise and then 180° counterclockwise to reset.

[0020] Turntable 4 is a circular metal disc structure, with its middle part connected to a servo motor via a bearing. The servo motor controls turntable 4 to rotate counterclockwise at a constant speed.

[0021] The second suction nozzle 2 and the third suction nozzle 3 are symmetrically installed on the edge of the turntable 4, and the center connecting line of the second suction nozzle 2 and the third suction nozzle 3 passes through the center of the turntable 4, and their suction surfaces are parallel to the cross-section of the turntable 4.

[0022] The glue gun 5 is mounted on one side of the turntable 4 via the glue head adjustment bracket 6. The glue head adjustment bracket 6 includes a horizontal adjustment slider and a vertical adjustment rod, which controls the glue gun 5 to make fine adjustments in the horizontal and vertical directions so that the glue nozzle can be aligned with the preset glue area on the label of the second suction nozzle 2 or the third suction nozzle 3, so as to avoid the glue spraying deviation, which would result in poor adhesion or label contamination.

[0023] The glue gun 5 is connected to an external glue supply system, and its control end is connected to the signal output end of the label detection photoelectric sensor 7 via a wire. The glue gun 5 will start spraying glue according to the preset glue amount and spraying time only when the label detection photoelectric sensor 7 detects that the second nozzle 2 or the third nozzle 3 has a label adsorbed.

[0024] Label slot 8 has a U-shaped structure. The width and depth of the slot can be adapted to the specifications of the labels, which can neatly store a batch of labels and prevent them from being scattered. The bottom of label slot 8 is equipped with an anti-slip pad, which can prevent the labels from sliding due to the suction force of the suction nozzle or slight vibration of the mechanism during the label picking process, ensuring that the label position is stable each time the label is picked up and improving the label picking success rate.

[0025] The bottom of the label slot adjustment seat 9 is equipped with a slide rail that slides along the horizontal direction of the labeling frame 11. The horizontal position of the label slot 8 can be adjusted by sliding to make the label slot and the label picking trajectory of the first suction nozzle 1 precisely aligned. This adapts to the label picking needs of different sized labels (such as when the label length changes, adjusting the position of the label slot ensures that the first suction nozzle can accurately pick up the label edge), improving the compatibility of the mechanism with different specifications of labels.

[0026] The label detection photoelectric sensor 7 is a diffuse reflection photoelectric sensor, and it is mounted on one side of the turntable 4 via a bracket. The detection end faces the movement trajectory of the second suction nozzle 2 or the third suction nozzle 3. When the second suction nozzle 2 or the third suction nozzle 3 carries the label through the detection area, the label detection photoelectric sensor 7 receives the reflected signal and outputs a high level, triggering the glue gun 5 to spray glue. If no label is detected, it outputs a low level, and the glue gun 5 does not operate.

[0027] The first suction nozzle 1 is fixed on the rotating shaft 10 and rotates with the rotating shaft 10; the second suction nozzle 2 or the third suction nozzle 3 is fixed on the turntable 4 and rotates with the turntable 4. The first suction nozzle 1 first picks up the label from the label slot 8, then rotates 180 degrees to directly above the second suction nozzle 2, which then catches it. Then the first suction nozzle 1 rotates 180 degrees counterclockwise back to below the label slot 8; the second suction nozzle 2 catches the label and then rotates 180 degrees counterclockwise. During the rotation, the label presence or absence is detected and adhesive is applied. Then the suction nozzle presses down to stick the label onto the product. During operation, the rotating shaft 10 rotates 180 degrees clockwise and then 180 degrees counterclockwise back, while the turntable 4 rotates counterclockwise continuously. The second suction nozzle 2 or the third suction nozzle 3 alternates.

[0028] During operation, the first suction nozzle 1 uses a soft rubber nozzle, greatly reducing the failure rate of ticket collection. The second suction nozzle 2 and the third suction nozzle 3 alternately collect and apply labels simultaneously, saving time and improving efficiency. After collecting the label, the second suction nozzle 2 and the third suction nozzle 3 are checked during rotation to ensure that the adhesive is applied only when there is a label, reducing product waste caused by unstable label collection. This significantly improves the overall efficiency and pass rate of the machine, greatly reduces the customer's operating costs, and improves social production efficiency.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
