Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a label cutting equipment. Background Art

[0002] In traditional tire tread production, vulcanized electronic tags serve as the sole identifier of the tire's identity throughout its circulation. However, with the advancement of intelligent manufacturing and the increasing automation in the tire industry, RFID (Radio Frequency Identification) tire tags are poised for widespread adoption. Before RFID tags are implanted in tires, they require pre-processing. For example, the RFID tag is encapsulated within a specially formulated rubber compound. After lamination, the plastic wrap is peeled off, followed by cutting, gripping, and labeling.

[0003] Currently, in order to achieve the cutting of electronic tags in the tire production process, a Chinese patent document with the announcement number CN208163829U discloses an electronic tag cutting device. After identifying and locating the material strip, the device uses a cutting mechanism to cut the individual chips in the material strip and transports the individual electronic tags formed after cutting to a placement position.

[0004] This method can only complete the positioning and cutting of a single label in one action cycle. For occasions with large-volume demands, this method is inefficient and difficult to meet the requirements.

DETAILED DESCRIPTION

[0044] The core of the present invention is to disclose a cutting unit for cutting equipment to effectively improve the efficiency of label cutting and meet the large-scale demand for label production.

[0045] Another core of the present invention is to disclose a cutting device having the above-mentioned cutting unit.

[0046] To help those skilled in the art better understand the present invention, embodiments of the present invention are described below with reference to the accompanying drawings. The embodiments described below do not limit the scope of the invention as set forth in the claims. Furthermore, the entire contents of the embodiments described below are not intended to be limiting as necessary to address the invention as set forth in the claims.

[0047] In existing electronic tag cutting equipment, the cutting process involves using a cutting module to cut the electronic tag strip, removing the electronic tag from the strip. Finally, the cutting module transports and ejects the removed electronic tag. In a single "positioning-cutting-transportation" cycle, the cutting module requires both cutting and transporting. Therefore, the cutting module cannot complete the cutting process while transporting the tag. This results in only one finished electronic tag being output per cycle, resulting in low efficiency.

[0048] To overcome these technical challenges, the inventors have devised a cutting unit for cutting equipment. This unit can complete the cutting of the strip while the cutting module is transporting the electronic tags, eliminating the need to wait for the cutting module to return, thereby improving work efficiency. For detailed structural details, please see the detailed implementation below.

[0049] The embodiment of the present invention discloses a cutting unit for a cutting device. The cutting unit is not limited to being used for cutting electronic labels, and any product that requires cutting off a portion of a material strip is applicable to the cutting unit.

[0050] like Figure 1 As shown, the cutting unit for the cutting device disclosed in the embodiment of the present invention includes a guide device 110, a cutting module 120 and a driving device 130. Among them:

[0051] The guide device 110 is used to limit the movement direction of the cutting module 120, so that the cutting module 120 moves back and forth in the predetermined direction of the guide device 110 to complete the switching of the cutting module 120 between different working positions. In this embodiment, the guide device 110 can be a slide rail or a slide groove commonly used in the prior art. Here, the guide device 110 is preferably a slide rail.

[0052] There are two cutting modules 120, both slidably mounted on the guide device 110. The cutting modules 120 are used to cut pieces from the material strip at the cutting position and release the cut pieces at the placement position. The cutting modules 120 need to reciprocate along the guide device 110 between the cutting position and the placement position to complete the cutting operation on the material strip at the cutting position and release the cut pieces at the placement position.

[0053] It should be noted that the structure of the cutting module 120 for realizing cutting and releasing actions is the same as the cutting module structure in the prior art. Both use a contoured hollow cavity cutter for cutting, and have a grabbing and ejecting mechanism inside the hollow cutter, which can transport and release the cut pieces.

[0054] The drive device 130 can drive the cutting modules 120 to move along the guide device 110, so that each cutting module 120 switches between a cutting position and a placement position. There are two placement positions, located on both sides of the cutting position. When one cutting module 120 is in the placement position, the other cutting module 120 is in the cutting position. The two cutting modules 120 correspond to a placement position respectively and share a cutting position. After one cutting module 120 cuts at the cutting position, it moves to its corresponding placement position to release the cutting piece. After the cutting module 120 leaves the cutting position, the other cutting module 120 moves to the cutting position to cut. After cutting is completed, it moves to its corresponding placement position to release the cutting piece, and this cycle repeats.

[0055] It should be noted that the driving device 130 may be a servo motor or a stepping motor. Here, the driving device 130 is preferably a servo motor.

[0056] The cutting unit for cutting equipment provided by the present invention is different from the prior art in that it achieves the purpose of outputting two cut pieces in a single cutting cycle by setting two cutting modules 120. Among them, both cutting modules 120 can slide on the guide device 110 in the cutting unit, and cut the pieces to be cut on the material strip when sliding to the cutting position, and release the cut pieces when sliding to the placement position. The driving device 130 used by the cutting unit 10 can drive the movement of the cutting module 120, and when the two cutting modules 120 are in the placement position during the movement, when one is in the cutting position, the other can complete the cutting action at the cutting position. The cutting unit for cutting equipment achieves the purpose of outputting two cut pieces in a single cycle through the coordinated movement of the two cutting modules 120.

[0057] In order to use only one drive device 130 to complete the movement of the two cutting modules 120, in a specific embodiment of the present invention, the cutting module 120 has two placement positions for placing labels, and they are symmetrically arranged on both sides of the cutting position where the cutting module 120 performs cutting, and the relative positions of the two cutting modules 120 are fixed. The distance between the two cutting modules 120 is equal to the distance between the cutting position and the placement position, so that when one cutting module 120 is in the placement position, the other cutting module is exactly in the cutting position. There is one drive device 130, and it is connected to one of the cutting modules 120. Since the relative positions of the two cutting modules 120 are fixed, when the drive device 130 drives one of the cutting modules 120 to move, the other cutting module 120 follows and moves synchronously.

[0058] To facilitate understanding of the cutting process in this embodiment, the two cutting modules 120 are respectively named the left cutting module and the right cutting module according to their different positions, and the two placement positions are respectively the left placement position and the right placement position. After cutting at the cutting position, the left cutting module moves leftward to the left placement position to release the cutting piece. While the left cutting module moves leftward, the right cutting module moves leftward synchronously. Since the distance between the cutting position and any placement position is equal to the spacing between the two cutting modules, when the left cutting module moves leftward to the left placement position, the right cutting module moves to the cutting position and completes the cutting process. After cutting at the cutting position, the right cutting module moves right to the right placement position to release the cutting piece. During the movement of the right cutting module to the right, the left cutting module moves to the right synchronously. Since the distance between the cutting position and any placement position is equal to the spacing between the two cutting modules, when the right cutting module moves right to the right placement position, the left cutting module just moves to the cutting position and completes the cutting work, completing a working cycle.

[0059] Furthermore, the guiding device 110 includes a transverse guide rail 111 and a mounting plate 112 that slides with the transverse guide rail 111. The two cutting modules 120 are both mounted on the same mounting plate 112. The driving device 130 controls the movement of the mounting plate 112 on the transverse guide rail 111, thereby driving the two cutting modules 120 to move to the cutting position and the placement position at the same time and perform cutting and placement actions.

[0060] It should be noted that there may be two driving devices 130 , which are connected to the two cutting modules 120 in a one-to-one correspondence, and the two cutting modules 120 are driven to move by their respective driving devices 130 .

[0061] To facilitate understanding of the cutting process in this embodiment, the two cutting modules 120 are respectively named as the left cutting module and the right cutting module according to their positions. The two placement positions are respectively the left placement position and the right placement position. The two driving devices are respectively named as the left driving device and the right driving device. The left driving device drives the left cutting module to cut at the cutting position, then moves leftward to the left placement position to release the cutting piece. During the movement of the left cutting module to the left, the right driving device drives the right cutting module to move leftward. When the left cutting module moves leftward to the left placement position, the right cutting module moves to the cutting position and completes the cutting operation. The right driving device drives the right cutting module to cut at the cutting position, then moves rightward to the right placement position to release the cutting piece. During the movement of the right cutting module to the right, the left driving device drives the left cutting module to move rightward. When the right cutting module moves rightward to the right placement position, the left cutting module moves to the cutting position and completes the cutting operation, thus completing one working cycle.

[0062] Furthermore, the guiding device 110 includes a transverse guide rail 111 and a mounting plate 112 that slides with the transverse guide rail 111. The two cutting modules 120 are respectively installed on the corresponding mounting plates 112. The two driving devices 130 respectively control the two mounting plates 112 to drive the two cutting modules 120 to alternately appear in the cutting position and the placement position.

[0063] like Figure 2 and Figure 3 As shown, the present invention also discloses a cutting device having the cutting unit 10 disclosed in the above embodiment. Because it includes the above cutting unit 10, it has all the technical effects of the above cutting unit 10, which will not be described in detail here. It should be noted that the cutting device disclosed in the embodiment of the present invention can include one cutting unit 10 or multiple cutting units.

[0064] In addition, the cutting device should also include a necessary conveying unit 40 for conveying the material strip. The conveying unit 40 can be the same as that in the prior art, that is, the conveying unit 40 can be a belt, a chain, or a felt conveyor belt. The improvement focus of this application is not on the conveying unit 40, so it will not be described in detail herein.

[0065] In order to further optimize the above technical solution, the cutting device disclosed in this embodiment further includes a visual detection unit 20 and a control unit.

[0066] The visual inspection unit 20 is used to detect the position of the piece to be cut on the material strip. The control unit is used to control the cutting module 120 at the cutting position to cut the piece to be cut when the visual inspection unit 20 detects that the piece to be cut on the material strip has moved to the cutting position. This increases the cutting accuracy of the cutting module 120 in cutting the piece to be cut on the material strip and avoids cutting the piece to be cut or cutting to other positions on the material strip.

[0067] It should be further explained that the visual detection unit 20 can be an eddy current sensor or an industrial vision camera. Here, it is preferred that the visual detection unit 20 is an industrial vision camera.

[0068] like Figure 3 and Figure 4 As shown, in order to further optimize the above technical solution, the cutting device disclosed in this embodiment also includes a material receiving unit 30 to collect the cut pieces after cutting. The material receiving unit includes:

[0069] The receiving plate 301 is arranged at a placement position;

[0070] The release film 302 is a transparent PET film with a front and back. The back of the film is coated and does not adhere to the rubber label. Therefore, when the release film 302 is transported and rolled into a roll, the label will not stick to the front of the release film 302 and will remain on the front of the release film 302. The release film 302 moves through the receiving plate 301, which is used to receive and transport the cut pieces released by the cutting module 120.

[0071] The receiving hub 305 is used for winding the isolation film 302;

[0072] The material receiving drive device 304 is used to pull the isolation film 302 to move to complete the material receiving action.

[0073] In the above technical solution, a receiving plate 301 is positioned in the storage position, its upper surface covered with a receiving isolation film 302. The cutting module 120 releases the cut pieces from the storage position and applies force to the receiving plate 301 to press the cut pieces together, securing them to the isolation film. After the cutting module 120 releases the cut pieces, the receiving drive 304 rotates the receiving hub 305, wrapping the collected isolation film 302 around it, thereby driving the isolation film 302 to complete the receiving operation.

[0074] To prevent material from piling up at the placement location, the cutting device disclosed in this embodiment also includes a first sensor 310 and a controller. The first sensor 310 is located at the placement location of the cut pieces on the receiving plate 301 and is used to detect whether a cut piece is on the isolation film 302 at that placement location. When the first sensor 310 detects a cut piece at the placement location, indicating that a cutting module 120 has released a cut piece at that placement location, the controller activates the receiving drive 304, pulling the isolation film 302 and removing the cut piece from the placement location.

[0075] It should be noted that the first sensor 310 here is preferably a self-reflective sensor.

[0076] In order to further optimize the above-mentioned solution, the cutting device disclosed in this embodiment further includes a first sensor 310, a second sensor 3320 and a controller. The first sensor 310 and the second sensor 320 are both arranged on the receiving plate 301, wherein the first sensor 310 is arranged at the cutting piece placement position on the receiving plate 301, and the second sensor 320 is arranged downstream of the first sensor 310. The first sensor 310 and the second sensor 320 are both used to detect whether there are cutting pieces at the corresponding detection positions of the sensors. When the first sensor 310 detects that there are cutting pieces at the placement position, the controller controls the receiving drive device 304 to start, pull the isolation film 302 to move, and take the cutting pieces away from the placement position, and when the second sensor 320 detects the cutting pieces, controls the receiving drive device 304 to stop the pulling action. When the first sensor 310 detects the cutting pieces at the placement position again, the controller controls the receiving drive device 304 to start again, and repeats this process. This technical solution can control the distance between two adjacent cut pieces by controlling the start and stop of the material receiving drive device 304 . The distance between two adjacent cut pieces is the detection range distance of the first sensor 310 and the second sensor 320 .

[0077] It should be noted that the first sensor 310 is preferably a self-reflective sensor, and the second sensor 320 is preferably a through-beam sensor.

[0078] like Figure 3 As shown, in order to further optimize the above-mentioned solution, the cutting equipment disclosed in this embodiment also includes a material receiving transverse guide rail 306. The material receiving transverse guide rail 306 is arranged below the material receiving unit 30 and slides with the material receiving unit 30 to facilitate maintenance personnel to perform maintenance on the inside of the cutting equipment, such as replacing wearing parts such as conveyor belts and synchronous belts, and provide sufficient space for equipment maintenance.

[0079] It should be noted that a material receiving transverse guide rail 306 is provided below at least one material receiving unit 30 .

[0080] In order to further optimize the above solution, the cutting device disclosed in this embodiment further includes a tensioning wheel 303. A plurality of tensioning wheels 303 are provided to tension the isolation film 302 to ensure that the isolation film can move smoothly when being pulled.

[0081] It should be noted that at least one tensioning wheel 303 is provided at the same height on each side of the receiving plate 301 to ensure that the isolation film 302 is in horizontal contact with the upper surface of the receiving plate 301. When the cutting module 120 is placed on the receiving plate 301 and releases the cut pieces, the cut pieces can be better pressed onto the isolation film 302.

[0082] The terms "first," "second," "left," and "right," etc., in the specification and claims of the present invention and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements and may include steps or elements that are not listed.

[0083] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
