Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a labeling machine with a labeling detection function. Background Art

[0002] Labeling machinery technology has evolved through manual labeling, simple mechanism-assisted labeling, semi-automatic labeling and semi-automatic labeling, and fully automatic labeling. When manufacturing products, to indicate the product's name and ingredients, people typically applied paste to paper and then adhered it to the product. However, this tedious and unprofitable method increased factory costs. To improve production efficiency, many workers came up with the idea of applying labels one by one to the product, using roller brushes and peelers. However, the adhesive strength of the paste was insufficient to meet the requirements of various industries. The emergence of self-adhesive labeling solved this problem, leading to the development of today's self-adhesive labeling machinery. In response to the diverse labeling requirements and the demand for high production efficiency across various industries, fully automatic paste labeling machines, self-adhesive labeling machines, rotary labeling machines, and fully automatic sleeve labeling machines have successively emerged.

[0003] A search revealed Chinese patent application number CN201210251612.9, which relates to the field of mechanical equipment technology, particularly a labeling device used to bond the chip, liner, and backing paper in an electronic tag. The liner / chip has a self-adhesive layer and is sequentially attached to a strip of release paper to form a self-adhesive label tape. The labeling device comprises a base for conveying the backing paper, a reel for placing the roll of self-adhesive label tape, a reel for rewinding the release paper tape after peeling the chip / liner, and a tensioning device and a peeling plate that sequentially constrain the release paper tape's conveyance path between the reel and reel. This invention proposes a labeling device that automatically bonds the RFID chip / liner to the backing paper during RFID tag production. The device boasts fast bonding speed and excellent results, significantly improving production efficiency and adapting to existing production lines. Its simple structure, reliable operation, low cost, low malfunction resistance, and easy adjustment make it suitable for producing RFID tags of varying specifications, demonstrating its excellent practical value.

[0004] The above-mentioned technical solution lacks a label breakage detection function. In actual production operations, label breakage may occur frequently due to quality problems of the label tape, improper operation, or failure to replace labels in time after they are used up. This affects labeling efficiency and may also affect product quality due to the inability to detect label breakage in time. Furthermore, failure to stop label rewinding and product conveying in a timely manner can easily lead to equipment damage and label omission. Therefore, developing a labeling device with a label breakage detection function is of great significance for improving labeling efficiency and product quality. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A labeling machine with a labeling detection function, comprising:

[0029] A base 1; a notch 2 is provided on the base 1, a conveying roller 3 for conveying objects is installed inside the notch 2, and a first side plate 4 and a second side plate 8 are provided on one side of the base 1;

[0030] A supply disk 5 for supplying labels is rotatably mounted on the upper end of one side of the first side panel 4, a first guide wheel 7 for guiding the label paper is rotatably mounted on one side of the supply disk 5 on the first side panel 4, and a winding disk 6 for winding the label tape is rotatably mounted on the lower end of one side of the first side panel 4; a winding motor 13 is fixedly mounted on the outer wall of the first side panel 4, and the winding motor 13 is connected to the shaft of the winding disk 6 by transmission.

[0031] The second side panel 8 is provided with a peeling plate 11 for peeling labels from the label paper. A second guide wheel 9 is provided at the upper end of one side of the second side panel 8 for receiving the label paper from the first guide wheel 7. The second guide wheel 9 is located between the peeling plate 11 and the first guide wheel 7. A third guide wheel 10 is provided at the lower end of the second side edge for conveying the label tape from the peeling plate 11 to the reel 6. An infrared sensor 12 is mounted on the second side panel 8, located on one side of the third guide wheel 10. Two sets of first protrusions 14 are symmetrically mounted on the second side panel 8 in the vertical direction. The transmitting and receiving ends of the infrared sensor 12 are respectively mounted on the two sets of first protrusions 14. A second protrusion 16 is also provided on the second side panel 8. The second protrusion 16 is located on the output side of the peeling plate 11. A laser displacement sensor 15 is mounted at the bottom of the second protrusion 16 to detect the passage of objects.

[0032] The product is conveyed by arranging a conveying roller 3 on the base 1. A first side plate 4 and a second side plate 8 are respectively arranged on one side of the base 1. A supply disk 5 and a winding disk 6 are arranged on the first side plate 4. A label stripping plate 11 and an infrared radiation sensor 12 are arranged on the second side. The infrared radiation sensor 12 can detect the occurrence of label breakage. When in use, the product is conveyed by the conveying roller 3. The supply disk 5 conveys the label paper to the label stripping plate 11 through the first guide wheel 7 and the second guide wheel 9. The label stripping plate 11 peels off the label paper, and the label tape is conveyed to the winding disk 6 through the third guide wheel 10.

[0033] At the same time, the laser displacement sensor 15 detects whether there is a product passing below. When a product appears, the rewinding motor 13 rewinds the label tape a certain distance, and the lower end of the peeling plate 11 sticks the label to the surface of the product to complete the labeling action. After a single product leaves the labeling area, the laser displacement sensor 15 continues to detect. Before the next product arrives, the rewinding motor 13 stops working, thus achieving the purpose of automatic labeling;

[0034] The device also includes a control panel installed on one side of the base 1. When the label paper is broken or used up, since an infrared counter-radiation sensor 12 is installed between the third guide wheel 10 and the winding wheel, when there is no label breakage, the light emitted by the transmitting end of the infrared counter-radiation sensor 12 is separated by the label tape. When there is a label breakage, the light emitted by the transmitting end of the infrared counter-radiation sensor 12 is not blocked by the label tape, and the receiving end receives the light. The infrared counter-radiation sensor 12 transmits the signal to the control panel. After receiving the signal, the control panel interrupts the operation of the equipment, including the operation of the winding motor 13 and the operation of the conveying roller 3, thereby realizing the label breakage detection function and avoiding the problems of idling and missing labels of the equipment.

[0035] Among them, the control method of the control panel of this application is to use a built-in PLC controller in the control panel. The control circuit of the PLC controller can be realized by simple programming by technical personnel in this field, which is common knowledge in this field, and this application document is mainly used to protect mechanical devices, so this application document no longer explains the control method and circuit connection in detail.

[0036] For further information, see Figure 4 In order to adapt to labeling products of different heights, this application makes the following design:

[0037] It further includes an adjusting mechanism for adjusting the labeling height. The adjusting mechanism includes a first support plate 17 and a screw rod 18. The first support plate 17 is arranged in a U-shape on the side of the base 1. The screw rod 18 is rotatably installed between the two arms of the first support plate 17. An adjusting motor 19 is installed on the top of the first support plate 17. The adjusting motor 19 is drivingly connected to the upper end of the screw rod 18. A sliding seat 20 is installed on the screw rod 18. One side of the sliding seat 20 is fixedly connected to the outer wall of the second side plate 8. A second support plate 21 is also arranged on the side of the base 1. The second support plate 21 is also arranged in a U-shape. A guide rod 22 is arranged between the two arms of the second support plate 21. A guide sleeve 23 is slidably sleeved on the guide rod 22. One side of the guide sleeve 23 is fixedly connected to the outer wall of the second side plate 8.

[0038] By starting the adjusting motor 19 to drive the screw rod 18 to rotate, the sliding seat 20 on the screw rod 18 can drive the second side plate 8 to move up and down, so that the distance between the label stripping plate 11 and the lower conveying roller 3 can be adjusted, thereby being able to adapt to products of different heights, greatly improving the applicability and scope of use of the device.

[0039] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations of the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
