Description

Technical Field

[0001] The present invention relates to the technical field of labeling machinery, and in particular to a fully automatic labeling system based on material identification. Background Art

[0002] Labels often carry specific information about the corresponding product and are generally attached to the product to provide users or customers with product information. However, to adapt to their internal product production management systems, product manufacturers often pre-laser-engraved internal identification codes on the product for internal identification. This facilitates identification of product information when the product is transferred between multiple stations during the production process. However, since these internal identification codes are encoded in a specific manner within the manufacturer, they are not universal and do not facilitate users or customers to obtain product information after the product is completed. Therefore, when the product is completed and shipped, it is usually necessary to convert the internal identification code into a universal identification code and affix it to the product in the form of a label so that users or customers can obtain product information.

[0003] However, when labeling products, the identification code labels corresponding to the same batch of products are usually printed out at once, and then workers have to affix them to the corresponding products one by one. This makes labeling inefficient. Moreover, because workers usually operate in batches, it is easy to cause labels to be affixed incorrectly, resulting in problems such as incorrect or garbled product codes. In addition, when labeling, workers do not have an accurate position reference standard, resulting in improper labeling. As a result, labels on products in the same batch are positioned differently, which makes it impossible to accurately read the identification code when batch binding or identification is performed. At the same time, crooked labels may also affect the appearance of the products. Even if there is a position reference standard, manual errors by workers are unavoidable, which may also cause labels to be affixed incorrectly. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a fully automatic labeling system based on material identification to solve the problems of low labeling efficiency and wrong or garbled product codes caused by labeling errors in the prior art.

[0025] The label printing mechanism is further used to print the identification code onto the label and intermittently convey the release paper and the label forward horizontally to the label output port according to a preset step length.

[0026] Furthermore, the labeling device is also used to separate the label attached to the release paper and carrying the second product information from the release paper and transfer it to the product to be labeled; the labeling device includes a label separation mechanism arranged at the label output port of the label printing mechanism and used to separate the printed label from the release paper to form a label to be attached, a label adsorption mechanism used to adsorb and attach the label to be attached on the label separation mechanism to the product to be labeled located at the processing position, and a driving mechanism that drives the label adsorption mechanism to carry the label from the separation mechanism to the processing position.

DETAILED DESCRIPTION

[0046] The following is further described in detail through specific implementation methods:

[0047] Example

[0048] like Figure 1 and Figure 2As shown, the fully automatic labeling system based on material identification of this embodiment includes a feeding device 1, a first identification device 2, a printing device 3, and a labeling device 4. Preferably, the fully automatic labeling system based on material identification of this embodiment may further include a controller 5, and the feeding device 1, the first identification device 2, the printing device 3, and the labeling device 4 are all electrically connected to and controlled by the controller 5. In this embodiment, a feeding position 1a and a processing position 1b are sequentially arranged at corresponding positions of the feeding device 1 along the feeding direction of the feeding device 1 (the feeding direction is defined as the X-axis direction, i.e., the length direction of the feeding device). The feeding device 1 is used to sequentially convey the product 100 to be labeled from the feeding port to the feeding position 1a and the processing position 1b along the feeding direction, and when the product is conveyed to the position, the product is restricted from continuing to be conveyed forward until the processing procedure at the current position is completed and the restriction on the product is lifted so that the product can continue to be conveyed forward and discharged; the first identification device 2 is provided on the feeding device 1 at a position corresponding to between the feeding position 1a and the processing position 1b, and is used to scan and identify the first product information of the product conveyed from the feeding position 1a and send the first product information to the printing device 3 synchronously by wire or wireless means. In this embodiment, In the embodiment, the first product information includes at least the name, model, production batch, production date, production department, responsible person and other product information that can be shared within the enterprise; the printing device 3 is arranged on one side of the feeding device 1 and corresponds to the processing position 1b, for receiving the first product information sent by the first identification device 2, and decoding the first product information to generate corresponding second product information to print on the label 82 and deliver the printed label 82 to the labeling device 4. In this embodiment, the second product information includes at least the name, model, production batch, production date and other product information that can be queried by users or customers; the labeling device 4 transfers the printed label 82 and attaches it to the product stopped at the processing position 1b, completing the fully automatic identification, decoding, printing and attachment of the label 82, thereby improving the labeling efficiency.

[0049] In this embodiment, to facilitate product transport and protect the products from damage, the products to be labeled 100 can be placed on a tray 6. During transport, the feeding device 1 moves the products to be labeled 100 to the destination position by conveying the tray 6, so that the products to be labeled 100 never come into direct contact with the corresponding structures of the conveying device, thereby preventing damage to the products to be labeled 100. It is understood that in other embodiments, the provision of the tray is not necessary. In specific implementations, the products to be labeled can also be placed directly on the feeding device for transport.

[0050] like Figure 3As shown, the tray 6 has a loading slot 6a that can accommodate products. The length of the loading slot 6a along the X-axis direction is adapted to the length of the product, and the width along the Y-axis direction is greater than the width of the product. A positioning slot 6b is provided on the slot wall corresponding to at least one long side of the loading slot 6a, which is recessed at least in the direction away from the other long side, so that workers or machines can push the product to the opposite side through the positioning slot 6b, so that the opposite side of the product is pressed against the slot wall of the loading slot 6a on the corresponding side, so as to ensure the relative position of the product and the tray 6.

[0051] like Figure 4 As shown, the feeding device 1 includes a conveying mechanism 11 and a processing stop mechanism 12. The conveying mechanism 11 is arranged on a frame 7 along the X-axis direction (the X-axis direction is also the length direction of the frame 7), and the processing position 1b is arranged on the conveying mechanism 11. The processing stop mechanism 12 is also arranged on the frame 7 and when the processing stop mechanism 12 is arranged on the frame 7, it corresponds to the processing position 1b, so that the processing stop mechanism 12 can perform positioning detection on the pallet 6 moved into position on the processing position 1b and timely limit the transmission of the pallet 6 and timely contact the restricted recovery transmission of the pallet 6.

[0052] The conveyor mechanism 11 can use any conveying structure or method to convey the tray 6 containing the products 100 to be labeled along the X-axis to the destination location, such as a belt conveyor, a roller conveyor, or any other transmission structure or method capable of moving along the X-axis. In this embodiment, to ensure smooth conveyance of the tray 6, the conveyor mechanism 11 uses a conveyor belt to convey the tray 6 and the products 100 to be labeled thereon.

[0053] In this embodiment, the processing position 1b has a first end and a second end arranged in sequence on the conveying mechanism 11 along the X-axis direction. After the tray 6 with the product 100 to be labeled is conveyed to the position along the X-axis direction, it can be positioned in the processing position 1b to confine the tray 6 at the processing position 1b, so as to facilitate the labeling device 4 to perform the labeling operation.

[0054] To detect, stop, and release the tray 6 that has moved to the processing position 1b, the processing stop mechanism 12 includes a processing detection module 121 disposed at a first end of the processing position 1b and a processing stop module 122 disposed at a second end of the processing position 1b. The processing detection module 121 is used to detect whether the tray 6 has been transferred to the processing position 1b, that is, whether the tray 6 has been transferred to the processing position 1b. The processing stop module 122 is used to restrict the tray 6 from continuing to move forward after the tray 6 has been transferred to the processing position until the labeling device 4 completes the labeling operation on the products to be labeled 100 placed in the tray 6. The restriction on the tray 6 is then released, allowing the tray 6 containing the labeled products to continue to be transferred forward for discharge.

[0055] In this embodiment, the processing detection module 121 is a first infrared sensing module disposed at the first end of the frame 7 corresponding to the processing position 1b. The first infrared sensing module is communicatively connected to the controller 5. The first infrared sensing module includes a first signal generator 1211 and a first signal receiver 1212, which are respectively disposed on both sides of the frame 7 along the width direction of the frame 7 (the width direction of the frame 7 is defined as the Y-axis direction, and the projection of the Y-axis direction on a horizontal plane is perpendicular to the X-axis direction). The signal transmitting end of the first signal generator 1211 is directly opposite the signal receiving end of the first signal receiver 1212, so that the first signal receiver 1212 can normally receive the infrared signal radiated by the first signal generator 1211. When the first infrared sensing module detects the tray 6, before the tray 6 enters the processing position 1b, there is no obstruction between the first signal receiver 1212 and the first signal generator 1211, and the first signal receiver 1212 can normally receive the infrared signal radiated by the first signal generator 1211. As the tray 6 moves forward, one end of the tray 6 first enters the processing position 1b and blocks the infrared signal radiated by the first signal generator 1211, preventing the first signal receiver 1212 from receiving the infrared signal radiated by the first signal generator 1211. At this time, the first signal receiver 1212 determines that the tray 6 has been transferred to the processing position 1b and sends a first blocking signal to the controller 5. The controller 5 controls the operation of the processing stop module 122 based on the received first blocking signal to limit the movement of the tray 6. It is understandable that in other embodiments, the processing detection module 121 can also be implemented using other structures capable of performing position detection, such as a switch, a proximity sensor, etc.

[0056] Preferably, the distance from the first end to the second end of the processing position 1b is not less than the length of the pallet 6 along the X-axis direction, so that the first infrared sensing module controls the operation of the processing stop mechanism through the controller 5 after sensing that the entire pallet 6 has entered the processing position 1b, so as to avoid the infrared signal being blocked by other structures outside the pallet 6 and mistakenly triggering the operation of the processing stop mechanism. Specifically, after receiving the first blocking signal, the controller 5 temporarily does not perform any operation on the processing stop module 122. At this time, the controller 5 will calculate the time required for the conveyor belt to transport the length of a pallet 6 forward based on the conveying speed of the conveyor belt and the length of the pallet 6. At the same time, the pallet 6 continues to be transported forward until the pallet 6 completely enters the processing position 1b and releases the blocking of the infrared signal, so that the first signal receiver 1212 receives the infrared signal radiated by the first signal generator 1211 again and sends the first in-position signal to the controller 5. The controller 5 matches the time difference between receiving the first blocking signal and receiving the first in-position signal with the calculated time required for the conveyor belt to transport a pallet 6, so as to determine whether the pallet 6 is being transported, and when the match is successful, controls the processing stop module 122 to act to limit the movement of the pallet 6, otherwise does not perform any operation to avoid accidentally triggering the processing stop module 122 and other subsequent components.

[0057] The processing stop module 122 includes a first stop block 1221 capable of moving toward or away from the conveyor 11 in a direction perpendicular to the conveyor 11 (the direction perpendicular to the conveyor 11 is defined as the Z-axis, which is perpendicular to the horizontal plane) and a first stop cylinder 1222 controlled by the controller 5 to drive the first stop block 1221 in the Z-axis direction. When the processing stop module 122 stops the pallet 6, when the pallet 6 enters the processing station 1b and is transferred to the designated position, the controller 5 controls the first stop cylinder 1222 to drive the first stop block 1221 toward the conveyor 11 in the Z-axis direction based on the first blocking signal and / or first arrival signal received from the first signal receiver 1212, thereby blocking the pallet 6 from further forward movement. When the product at the processing station 1b is completely labeled, the controller 5 controls the first stop cylinder 1222 to drive the first stop block 1221 away from the conveyor 11 in the Z-axis direction, thereby releasing the restraint on the pallet 6 and allowing it to continue to be transferred forward. It is understandable that in some other embodiments, the first stop cylinder 1222 can also drive the first stop block 1221 to extend along the Y-axis direction to limit the tray 6 or retract to release the restriction on the tray 6. At the same time, the first stop cylinder 1222 can also adopt other driving structures to realize the driving of the first stop block 1221, such as using an electric push rod 141, a linear motor, etc. to replace the first stop cylinder 1222.

[0058] In this embodiment, the first stop cylinder 1222 is fixedly disposed on a first mounting bracket 71. The first mounting bracket 71 is in a "冂" shape and includes first mounting seats respectively erected on both sides of the frame 7 along the Y-axis direction and a cross bar disposed above the conveying mechanism 11 and connecting the tops of the two mounting seats. A conveying channel for the tray 6 to pass through is formed between the first cross bar and the conveying mechanism 11. When the first stop block 1221 approaches the conveying mechanism 11 along the Z-axis direction under the drive of the first stop cylinder 1222 and moves into place, the conveying channel is blocked to restrict the tray 6 from passing through the conveying channel. When the first stop block 1221 moves away from the conveying mechanism 11 along the Z-axis direction under the drive of the first stop cylinder 1222 and moves into place, the conveying channel is opened to release the restriction on the tray 6, enabling the tray 6 to pass through the conveying channel and enter the next process. <"0000139"><"0000140">As a preferred mode of this embodiment, the feeding device further includes a feeding stop mechanism 13 for positioning and detecting the feeding position 1a of the product to be labeled 100 and a product positioning mechanism 14 for pre-labeling positioning of the product to be labeled 100 conveyed to the feeding position 1a and placed in the tray 6. When the tray 6 is conveyed from the feeding port to the feeding position 1a by the conveying mechanism 11, the product positioning mechanism 14 can position the product in the tray 6, so that when the tray 6 is conveyed to the processing position 1b, each product has the same relative position, thereby ensuring the consistency of the positions of the product labels 82 after labeling. In this embodiment, the feeding position 1a is formed between the feeding port and the processing position 1b. <"0000141"><"0000142">In this embodiment, the feeding position 1a has a first end and a second end arranged in sequence on the conveying mechanism 11 along the X-axis direction. After the tray 6 with the product to be labeled 100 is conveyed into place along the X-axis direction, it can be positioned within the feeding position 1a to restrict the tray 6 at the feeding position 1a, facilitating the product positioning mechanism 14 to perform pre-labeling positioning on the product placed in the tray 6. <"0000143"><"0000144">To detect, stop, and release the tray 6 that moves to the feeding position 1a, the feeding stop mechanism 13 includes a feeding detection module disposed at the first end of the feeding position 1a and a feeding stop module 132 disposed at the second end of the feeding position 1a. The feeding detection module is used to detect whether the tray 6 is conveyed into place, that is, to detect whether the tray 6 is conveyed to the feeding position 1a. The feeding stop module 132 is used to restrict the tray 6 from continuing to convey forward after the tray 6 is conveyed into place until the product positioning mechanism 14 completes the pre-labeling positioning of the product to be labeled 100 placed in the tray 6 and then releases the restriction on the tray 6, enabling the tray 6 containing the labeled product to continue to convey forward for labeling processing. <"0000145">

[0062] In this embodiment, the feeding detection module is a second infrared sensing module arranged at the first end of the frame 7 corresponding to the feeding position 1a; the structure of the second infrared sensing module is the same as that of the first infrared sensing module, including a second signal generator 1311 and a second signal receiver 1312 relatively arranged on both sides of the frame 7, and the detection process and signal processing process of the second signal generator 1311 and the second signal receiver 1312 for the tray 6 are the same as the detection process and signal transmission process of the first signal generator 1211 and the first signal receiver 1212 for the tray 6. For the specific detection process and signal transmission process of the second signal generator 1311 and the second signal receiver 1312 for the tray 6, please refer to the relevant description of the first infrared sensing module, which will not be repeated here.

[0063] The feed stop module 132 includes a second stop block 1321 that can move toward or away from the conveyor mechanism 11 along the Z-axis direction, and a second stop cylinder 1322 controlled by the controller 5 to drive the second stop block 1321 to move along the Z-axis direction. When the feed stop module 132 stops the tray 6, when the tray 6 enters the feed position 1a and is conveyed to the position, the controller 5 controls the second stop cylinder 1322 to drive the second stop block 1321 toward the conveyor mechanism 11 along the Z-axis direction based on the second blocking signal and / or second position signal received from the second signal receiver 1312, so as to block the tray 6 from continuing to move forward. When the product at the feed position 1a is positioned before labeling, the controller 5 controls the second stop cylinder 1322 to drive the second stop block 1321 away from the conveyor mechanism 11 along the Z-axis direction, so as to release the restriction on the tray 6 and allow the tray 6 to continue to be conveyed forward. In this embodiment, the second stop cylinder 1322 is fixed on a second mounting bracket 72 . The structure of the second mounting bracket 72 is the same as that of the first mounting bracket 71 . For details, please refer to the relevant description of the first mounting bracket 71 , which will not be repeated here.

[0064] like Figure 5As shown, the product positioning mechanism 14 is provided at the feed position 1a of the conveying mechanism 11; it is used to position the tray 6 on the conveying mechanism 11 relative to the conveying mechanism 11 and / or to position the product 100 to be labeled placed in the tray 6 relative to the tray 6, so that the tray 6 and the product 100 to be labeled conveyed forward through the feed position 1a always maintain the same position along the X-axis direction on the conveying mechanism 11, thereby ensuring the consistency of the subsequent labeling position. In this embodiment, the product positioning mechanism 14 includes a push rod 141, a first product positioning cylinder 142, a second product positioning cylinder 143 and a product cylinder mounting seat 144; the product cylinder mounting seat 144 is upright on one side of the frame 7, the second product positioning cylinder 143 is fixedly mounted on the product cylinder mounting seat 144, the first product positioning cylinder 142 is fixedly mounted on the output shaft of the second product positioning cylinder 143, and the second product positioning cylinder 143 is used to drive the first product positioning cylinder 142 drives the push rod 141 to approach or move away from the pallet 6 and / or the product to be labeled 100 along the Z-axis direction, and makes the push rod 141 extend into the positioning groove 6b along the Z-axis direction; the push rod 141 is fixedly mounted on the output shaft of the first product positioning cylinder 142, and the first product positioning cylinder 142 is used to drive the push rod 141 to approach or move away from the pallet 6 and / or the product to be labeled 100 along the Y-axis direction; the push rod 141 is enabled to push the pallet 6 and / or the product to be labeled 100 sideways along the Y-axis direction to position the push rod 141. Specifically, the first product positioning cylinder 142 and the second product positioning cylinder 143 are both electrically connected to the controller 5. When the tray 6 moves into position on the feeding position 1a, it is stopped by the second stop module. At this time, the controller 5 will first control the second product positioning cylinder 143 to drive the first product positioning cylinder 142 and the push rod 141 to move downward along the Z-axis direction to the limit (that is, the push rod 141 enters the positioning groove 6b along the Z-axis direction and contacts the bottom of the loading groove 6a), and then control the first product positioning cylinder 142 to push the product to be labeled 100 sideways along the Y-axis direction, so that the opposite side of the product to be labeled 100 is in close contact with the groove wall of the loading groove 6a on the corresponding side, thereby realizing the positioning of the product to be labeled 100 in the tray 6. It is understandable that in some other embodiments, the first product positioning cylinder 142 and / or the second product positioning cylinder 143 can also adopt other driving methods to respectively drive the push rod 141 and the first product positioning cylinder 142 to move, for example, using an electric push rod 141, a linear motor, etc. to replace the first product positioning cylinder 142 and / or the second product positioning cylinder 143.

[0065] In this embodiment, in order to increase the accuracy of the subsequent first identification device 2 in identifying the first product information of the product to be labeled 100 and the consistency of the position of the labeling device 4 during labeling, after the product to be labeled 100 is closely attached to the wall of the loading slot 6a, the controller 5 can further control the first product positioning cylinder 142 to continue to push the product to be labeled 100 laterally along the Y-axis direction. Since the product to be labeled 100 is now closely attached to the wall of the loading slot 6a, the first product positioning cylinder 142 will push the tray 6 to move synchronously when continuing to push the product to be labeled 100, so as to adjust and position the position of the tray 6 relative to the feeding mechanism. Of course, positioning the tray 6 in this embodiment is not necessarily provided. In some other embodiments, such as when the width of the conveying position on the conveying mechanism 11 in the Y-axis direction just matches the width of the tray 6 or the accuracy requirement is relatively low, the first product positioning cylinder 142 can stop and reset after completing the positioning of the product to be labeled 100 relative to the tray 6, so as to shorten the positioning time and further improve the labeling efficiency.

[0066] The first identification device 2 is disposed on the frame 7 along the X-axis, at a side corresponding to the second end of the feed position 1a and away from the first end of the feed position 1a, for identifying the product 100 to be labeled conveyed through the feed position 1a and reading the first product information of the product 100 to be labeled. The first identification device 2 is fixed to a third mounting bracket disposed on the frame 7. The structure of the third mounting bracket is the same as that of the first mounting bracket 71 and / or the second mounting bracket 72. In this embodiment, to simplify the structure of the frame 7, the third mounting bracket is the first mounting bracket 71, that is, the first identification device 2 and the second stop module share the first mounting bracket 71.

[0067] In this embodiment, the first product information is carried in an internal identification code that is pre-laser-engraved or posted on the product to be labeled 100. The internal identification code is preferably a QR code, so that when the product is transferred between various processing steps, each processing step can identify and read the first product information of the product through the QR code. Specifically, in conjunction with the example, the first identification device 2 is a scanning head installed on the frame 7 (specifically the first mounting frame 71), and the scanning end of the scanning head is facing the conveying mechanism 11. When the product to be labeled 100 is conveyed to the bottom of the scanning head on the conveying mechanism 11, the scanning head can scan the QR code and read the first product information carried in the QR code and send it to the printing device 3. Of course, in some other embodiments, the first identification device 2 can also be replaced by other identification structures such as scanners and barcode scanners that can identify the internal identification code and read the first product information.

[0068] like Figure 6 、 Figure 7 and Figure 8As shown, the printing device 3 is disposed on one side of the conveying device and communicates with the first identification device 2 via a wired or wireless method. The printing device 3 includes an information processing module 31, an information writing module 32, and a label printing mechanism 33. The information processing module 31 receives the first product information transmitted from the first identification device 2, transcodes the first product information into second product information, and transmits it to the information writing module 32. Transcoding refers to converting the format of the first product information, which can only be recognized and read internally, into a universal format that can be recognized and obtained by users and customers. The information writing module 32 receives the second product information transmitted by the information processing module 31, encodes the second product information according to preset encoding rules to generate a universal identification code (a barcode in this embodiment, for which encoding rules refer to the encoding rules of barcodes). The second product information is then written into the generated identification code, so that the identification code carries the corresponding second product information, and the identification code is transmitted to the label printing mechanism 33. The label printing mechanism 33 receives the identification code and prints it on the label 82 for the labeling device 4 to absorb and apply the label 82. In this embodiment, the information processing module 31 and the information writing module can be built into the label printing mechanism 33 in the form of application software to achieve the reception and transcoding of the first product information, the writing of the second product information and the printing of the label 82 .

[0069] The label printing mechanism 33 has a label output port 33a connected to the labeling device 4 to convey the printed label 82 to the labeling device 4; the label printing mechanism 33 is loaded with a label 82 roll (not shown), and the label 82 roll is wound by a release paper 81 with a number of blank labels 82 evenly attached. After receiving the identification code, the label printing mechanism 33 prints the identification code on the label 82 closest to the label output port 33a, and the controller 5 controls the label 82 roll to output the printed label 82 from the label output port 33a according to a preset step length. The preset step length is the conveying distance of the label 82 or the release paper 81 in its horizontal conveying direction (the Y-axis direction in this embodiment); in this embodiment, the preset step length is greater than the dimension of the label 82 along the length direction of the release paper 81 to ensure that all single labels 82 are output from the label output port 33a. In addition, after the current label 82 is transmitted out of the label output port 33a, the controller 5 controls the label 82 roll to stop conveying the label 82, and synchronously controls the label printing mechanism 33 to print the next label 82 and the labeling mechanism to absorb the current label 82. After the next label 82 is printed and the current label 82 has been absorbed by the labeling mechanism, the controller 5 controls the label 82 roll to convey the label 82 forward again, thereby realizing intermittent conveyance of the label 82 to avoid label 82 posting errors.

[0070] The labeling device 4 is capable of receiving the label 82 delivered by the label printing mechanism 33. Specifically, after the label 82 is printed and output through the label delivery port 82, the labeling device 4 separates the label 82 attached to the release paper 81 and carrying the second product information from the release paper 81 and transfers the label 82 to the product 100 to be labeled at the processing position 1b.

[0071] like Figure 9 As shown, the labeling device 4 includes a platform 45, a label separation mechanism 41, a label suction mechanism 42, a drive mechanism 43, and a recovery mechanism 44 disposed on the platform 45. A partition 46 is fixedly positioned in the middle of the platform 45, dividing the platform 45 into an upper space and a lower space. The label separation mechanism 41 is disposed on the partition 46 and corresponds to the upper space. The label separation mechanism 41 corresponds to the label output port 33a of the label printing mechanism 33 and is configured to receive labels 82 fed from the label printing mechanism 33, separate the labels 82 from the release paper 81, and place them in a corresponding position within the label separation mechanism 41. The label suction mechanism 42 is disposed in the upper space above the partition 46 and is capable of reciprocating between the upper space and the processing station 1b. It is configured to absorb labels 82 from the label separation mechanism 41 and transfer the absorbed labels 82 to the processing station 1b for attachment to the product 100 to be labeled. The drive mechanism 43 is disposed in the upper space and fixed to the top of the machine table 45. The drive mechanism 43 corresponds to the position of the processing station 1b and is used to drive the label adsorption mechanism 42 to reciprocate between the upper space and the processing station 1b along the Y-axis and the Z-axis to transfer the label 82. The recovery mechanism 44 is disposed below the label separation mechanism 41 and is used to recover the release paper 81 after the label 82 is separated from the release paper 81.

[0072] like Figure 10 and Figure 11As shown, the label separation mechanism 41 includes a label receiving platform 411, a label separation platform 412, and a label separation plate 413. The surface of the label receiving platform 411 is connected to the label outlet 33a and is used to receive and support the release paper 81 and the label 82 to be attached. The label separation platform 412 is arranged relative to the label receiving platform 411 along the Y-axis, on the side away from the label outlet 33a. The label separation plate 413 is arranged on the surface of the label separation platform 412 and is used to separate the label 82 from the release paper 81. In this embodiment, the upper surface of the label separation plate 413 is coated with a non-stick material to prevent the label 82 from sticking to the label separation plate 413. When the release paper 81 with the label 82 to be attached is supported on the label receiving platform 411, the upper surface of the label separation plate 413 is at the same horizontal position as the upper surface of the release paper 81, so that the label 82 can be horizontally peeled off onto the label separation plate 413 to avoid damage to the label 82.

[0073] In this embodiment, there is a gap on the opposite side of the label separation table 412 and the label receiving table 411 to form a recovery channel 44a for the release paper 81. After the release paper 81 is output through the label output port 33a, it enters the recovery channel 44a along the entrance of the table sub-recovery channel 44a of the label receiving table 411 and is recovered through the recovery channel 44a; in this embodiment, in order to facilitate the separation of the label 82, the recovery channel 44a and the table surface of the label receiving table 411 are set at a preset angle (preferably an acute angle in this embodiment to facilitate the separation of the label 82 from the release paper 81), so that after the release paper 81 enters the recovery channel 44a, it bends downward to separate the frontmost label 82 from the release paper 81 first, and as the release paper 81 is recovered, it is gradually separated from the release paper 81 and transported to the label separation plate 413. Preferably, the width of the recycling channel 44a is greater than the thickness of the release paper 81, and one end of the label separation plate 413 extends horizontally toward the label receiving platform 411 and its projection on the horizontal plane at least partially covers the recycling channel 44a, so that the distance between the end of the label separation plate 413 and the corresponding position of the label receiving platform 411 is slightly greater than the thickness of the release paper 81 and less than the overlapping thickness of the release paper 81 and the label 82, so that only the release paper 81 can pass between the end of the label separation plate 413 and the label receiving platform 411, thereby avoiding the label 82 being recycled and causing incorrect labeling or missing labeling.

[0074] To ensure stable adsorption of the label 82 by the label adsorption mechanism 42, the label adsorption mechanism 42 of this embodiment uses a vacuum suction head connected to a vacuum channel to achieve adsorption of the label 82. In other embodiments, the label adsorption mechanism 42 can also use other adsorption methods, such as a negative pressure suction head instead of the vacuum suction head.

[0075] The driving mechanism 43 includes a suction drive cylinder 431 that drives the label suction mechanism 42 toward or away from the label to be attached 82 or the processing position 1b along the Z-axis direction, and a reciprocating cylinder 432 that is fixed to the machine table 45 and drives the suction drive cylinder 431 to reciprocate between the label to be attached 82 and the product to be labeled 100 in the Y-axis direction. The label suction mechanism 42 is fixed to the output shaft of the suction drive cylinder 431 so as to move along the Z-axis under the drive of the suction drive cylinder 431. In this embodiment, the reciprocating cylinder 432 is a rodless cylinder to save installation space and make the structure of the labeling device 4 more compact. The guide rod of the rodless cylinder is arranged along the Y-axis direction, and the suction drive cylinder 431 is fixed to the sliding seat of the rodless cylinder. When the sliding seat slides along the guide rod under the drive of the cylinder body of the rodless cylinder, it drives the suction drive cylinder 431 to move along the Y-axis direction. It is understandable that in some other embodiments, the adsorption drive cylinder 431 and / or the reciprocating cylinder 432 can also adopt other driving methods or structures to respectively drive the movement of the label adsorption mechanism 42 and the adsorption drive cylinder 431, for example, using an electric push rod 141, a linear motor, etc. to replace the adsorption drive cylinder 431 and / or the reciprocating cylinder 432.

[0076] The recycling mechanism 44 includes a recycling wheel 441 arranged in the lower space, a driving motor 442 for driving the recycling wheel 441, and at least one tensioning wheel 443 arranged in the upper space; the end of the release paper 81 at least partially surrounds and is tensioned on the outer circumference of the tensioning wheel 443 through the outlet of the recycling channel 44a, and is then connected to the recycling wheel 441 in a direction tangential to the recycling wheel 441. The output shaft of the driving motor 442 is fixedly connected to the axle of the recycling wheel 441, and rotates intermittently according to the preset step size to pull the release paper 81 to achieve the recycling of the release paper 81. In this embodiment, in order to improve the tensioning effect of the release paper 81 and thus make it easier for the label 82 to separate from the release paper 81, two tensioning wheels 443 are provided in the upper space; specifically, a mounting plate is erected on the two opposite sides of the opening 46a of the partition 46, and the tensioning wheel 443 is rotatably arranged between the two mounting plates in an upper and lower structure, and the projections of the axis lines of the two tensioning wheels 443 on the horizontal plane are preferably staggered. The release paper 81 coming out of the recovery channel 44a is in an "S" shape, bypasses the two tensioning wheels 443, and is then connected to the recovery wheel 441 in a direction tangent to the recovery wheel 441, so that relatively appropriate friction is maintained between the release paper 81 and the wheel surfaces of the two tensioning wheels 443, thereby improving the tensioning effect of the release paper 81.

[0077] Please refer back to Figure 1 and Figure 2As a preferred embodiment of this embodiment, a second identification device 9 is further provided at the discharge position 1c of the conveyor mechanism 11 along the feeding direction of the conveyor mechanism 11. The second identification device 9 is used to identify the second product information carried on the label 82, associate the second product information with the corresponding product, and upload it to the server for querying and tracing the product information. Specifically, in this embodiment, the second identification device 9 is fixed to a fourth mounting bracket 73 provided on the frame 7. The structure of the fourth mounting bracket 73 is the same as that of the first mounting bracket 71, the second mounting bracket 72, and / or the third mounting bracket. The second identification device 9 is a scanning head mounted on the fourth mounting bracket 73. The scanning end of the scanning head faces the conveyor mechanism 11. When the labeled product is transferred from the processing position 1b to the discharge position 1c on the conveyor mechanism 11 and is located below the scanning head, the scanning head can scan the identification code on the label 82 and read the second product information carried in the identification code, associate the second product information with the corresponding product, and upload it to the server. Similarly, in some other embodiments, the second identification device 9 can also be replaced by a scanner, a barcode scanner, or other identification structures that can identify the identification code and read the second product information.

[0078] When working in this embodiment, workers place the products 100 to be labeled in the tray 6 one by one, and carry them one by one to the feed port of the conveying mechanism 11, so that the conveying mechanism 11 conveys the tray 6 along the X-axis direction in sequence;

[0079] When the tray 6 enters the feeding position 1a and blocks the infrared signal radiated by the second signal generator 1311, the second signal receiver 1312 cannot receive the infrared signal radiated by the second signal generator 1311. At this time, the second signal receiver 1312 determines that the tray 6 is conveyed to the feeding position 1a and sends a second blocking signal to the controller 5. The controller 5 controls the second stop cylinder 1322 to drive the second stop block 1321 to move along the Z-axis direction to the limit according to the received second blocking signal so that the second stop block 1321 is against the conveying mechanism 11 to block the tray 6. At the same time When the tray 6 moves to the feeding position 1a, the controller 5 will first control the second product positioning cylinder 143 to drive the first product positioning cylinder 142 and the push rod 141 to move downward to the limit along the Z axis direction, so that the push rod 141 enters the positioning groove 6b along the Z axis direction and contacts the bottom of the loading groove 6a. Then, the controller 5 will control the first product positioning cylinder 142 to push the product 100 to be labeled along the Y axis direction, so that the opposite side of the product 100 to be labeled is in close contact with the groove wall of the loading groove 6a on the corresponding side. After the positioning of the product 100 to be labeled is completed, the second product positioning cylinder 143 and the first product positioning cylinder 142 are reset in sequence.

[0080] When the positioning of the product 100 to be labeled is completed, the controller 5 controls the second stop cylinder 1322 to drive the second stop block 1321 to reset along the Z-axis direction, releasing the restriction on the tray 6, and the tray 6 continues to be transported along the X-axis under the transport of the conveying mechanism 11. When passing through the first scanning device, the first scanning device scans the internal identification code on the product 100 to be labeled, reads the first product information carried in the internal identification code, and synchronously sends the first product information to the information processing module 31. The information processing module 31 receives the first product information and transcodes the first product information to obtain the second product information and sends it to the information writing module Block 32, the information writing module 32 receives the second product information, encodes the second product information to generate an identification code, writes the second product information into the identification code, and then sends the identification code to the label printing mechanism 33. The label printing mechanism 33 receives the identification code and prints the identification code on the label 82 closest to the label output port 33a. The controller 5 controls the label 82 to roll the printed label 82 from the label output port 33a to the label receiving platform 411 according to the preset step length and cooperates with the label separation plate 413 to separate the label 82 onto the label separation plate 413. At this time, the tray 6 continues to be transported forward;

[0081] When the tray 6 enters the processing position 1b and blocks the infrared signal radiated by the first signal generator 1211, the first signal receiver 1212 cannot receive the infrared signal radiated by the first signal generator 1211. At this time, the first signal receiver 1212 determines that the tray 6 is transmitted to the processing position 1b and sends a first blocking signal to the controller 5. The controller 5 controls the first stop cylinder 1222 to drive the first stop block 1221 to move along the Z-axis direction to the limit according to the received first blocking signal so that the first stop block 1221 is against the conveying mechanism 11 to block the tray 6; at the same time, the controller 5 controls the adsorption drive mechanism 43 to drive the label adsorption mechanism 42 to descend along the Z-axis direction to the label separation plate 413 and absorb the label on the label separation plate 413 82, the controller 5 controls the adsorption drive mechanism 43 to reset along the Z-axis direction and then controls the reciprocating mechanism to drive the adsorption drive mechanism 43 and the label adsorption mechanism 42 to move along the Y-axis direction to above the processing position 1b. During this process, the label adsorption mechanism 42 continues to adsorb the label 82; after the label adsorption mechanism 42 moves into position, the controller 5 controls the adsorption drive mechanism 43 to approach the product 100 to be labeled on the processing position 1b along the Z-axis direction and controls the label adsorption mechanism 42 to release the adsorption of the label 82 when the label adsorption mechanism 42 contacts the surface of the product 100 to be labeled, and controls the adsorption drive mechanism 43 to lightly press the surface of the product 100 to be labeled so as to stick the label 82 to the product. Finally, the controller controls the adsorption drive mechanism 43 and the reciprocating mechanism to reset in sequence to wait for the next labeling.

[0082] When labeling is completed, the controller 5 controls the first stop cylinder 1222 to drive the first stop block 1221 to reset along the Z-axis direction, releasing the restriction on the pallet 6. The pallet 6 continues to be transported to the discharge position 1c, and after being scanned, identified and bound by the second identification device 9 and uploaded, it continues to be passed back to the next workstation to complete the fully automatic labeling of the product.

[0083] The fully automatic labeling system based on material identification in this embodiment identifies and reads the first product information of the product by setting up a first identification device 2, a printing device 3 and a labeling device 4, and synchronously transmits it to the printing device 3 for transcoding to form the second product information, which is then written into an identification code and printed on the label 82. The labeling device 4 then absorbs the label 82 and attaches it to the product. The entire process is automatically completed by the system, which can effectively improve the labeling efficiency. In addition, the system adopts a method of identifying, printing and labeling at the same time, without manual operation, which can effectively avoid the label 82 from being attached incorrectly, and thus ensure that the label 82 always corresponds to the product, thereby avoiding the problem of wrong code or garbled code in the product identification code.
