Description

Technical Field

[0001] The present invention belongs to the technical field of automation, and in particular relates to a labeling device and a textile labeling method. Background Art

[0002] In the existing textile industry, most labeling is done manually, with low intelligence, low automation, high labor costs, and it is easy to cause missed labeling and mislabeling.

[0003] In this way, the manual labor intensity of labeling is high. Workers need to keep an eye on the defects of the fabric all the time. After a long time, their eyes are prone to fatigue, which also causes certain harm to the eye health of the human body.

[0004] Moreover, most textile labeling machines are relatively large in size, cannot be well compatible with fabric inspection machines, have complex structures, and are not high in economy, applicability, practicality, and operability, and the labeling accuracy is not high.

[0005] In summary, there is an urgent need to provide a labeling device and a textile labeling method that can improve efficiency and solve the disadvantages of traditional manual labeling, such as harming the eyes, low efficiency, high missed inspection rate, and high error rate. Summary of the Invention

[0006] The purpose of the present invention is to provide a labeling device and a textile labeling method that can improve efficiency and solve the disadvantages of traditional manual labeling, such as harming the eyes, low efficiency, high missed inspection rate, and high error rate.

[0007] The above object is achieved through the following technical solutions: A labeling device includes a carrier and a label releasing roller assembly, a driving roller assembly, a pressing roller assembly, a label collecting roller assembly, a label stripping assembly, and a label pressing roller assembly arranged on the carrier. The label releasing roller assembly is used to carry label paper. The driving roller assembly includes a driving roller shaft, a driving roller, a second synchronous pulley, and a driving member. The driving member is in transmission connection with the driving roller shaft. The driving roller and the second synchronous pulley are fixedly arranged on the driving roller shaft. The pressing roller assembly cooperates with the driving roller to adjust the friction force between the label paper and the driving roller assembly. The label stripping assembly includes a label stripping plate and a label pressing plate. The label stripping plate is provided with a label stripping sharp corner for separating the label from the label paper. The label pressing roller assembly includes a fixed seat, a fixing plate, a label pressing roller, an elastic member, a vertical guiding member, and an anti-falling seat. The fixed seat is fixed on the carrier. The elastic member is arranged between the fixed seat and the fixing plate. One end of the vertical guiding member is connected to the anti-falling seat, and the other end passes through the fixed seat and the elastic member and is connected to the mounting plate. The elastic member applies a downward force to the fixing plate. The label pressing roller is hinged to the fixing plate through a roller shaft. The label pressing roller can elastically float vertically along the vertical guiding member. The label pressing roller is arranged above the end of the label stripping assembly. The label collecting roller assembly includes a label collecting shaft, a label collecting roller, a pressing rod, and a first synchronous pulley. The label collecting roller and the first synchronous pulley are fixedly arranged on the label collecting shaft. The pressing rod is arranged on the label collecting roller and is used to press the starting end of the label paper on the label collecting roller. The first synchronous pulley is connected to the second synchronous pulley through a synchronous belt.

[0008] In the specific application process, the label paper is installed on the label releasing roller assembly. The starting end of the label paper passes between the driving roller of the driving roller assembly and the pressing roller assembly, and then passes between the label stripping plate and the label pressing plate. After the label paper bypasses the label stripping sharp corner of the label stripping plate, the starting end of the label paper adheres to the label collecting roller of the label collecting roller assembly. The pressing rod presses the starting end of the label paper on the label collecting roller, and it can rotate with the label collecting roller of the label collecting roller assembly. The driving member moves, driving the second synchronous pulley and the driving roller to rotate, adjusting the pressure between the pressing roller assembly and the driving roller, thereby adjusting the friction force between the label paper and the driving roller. The label paper is pulled under the action of the friction force, causing the label releasing roller on the label releasing roller assembly to rotate, making the label paper rotate slowly. The second synchronous pulley rotates to drive the synchronous belt to drive the first synchronous pulley to rotate, thereby driving the label collecting roller and the pressing rod of the label collecting roller assembly to rotate. Since the starting end of the label paper is pressed by the pressing rod and the label collecting roller, when the label collecting roller rotates, the starting end of the label paper rotates with the label collecting roller. When the label collecting roller and the label releasing roller rotate simultaneously, the entire part of the label paper operates. When passing through the label stripping plate, through the label stripping sharp corner of the label stripping plate, the label is separated from the label paper, realizing the label stripping process. At this time, the label pressing roller presses the label on the object to be labeled under the elastic force of the elastic member.

[0009] The present invention realizes label releasing, label collecting, and label pasting through a driving member, with simple power and high efficiency, and can achieve fully automatic label pasting, solving the disadvantages of traditional manual label pasting such as eye damage, low efficiency, high missed inspection rate, and high error rate.

[0010] A further technical solution is that the label collecting roller assembly further includes an adjusting assembly. The label collecting roller is arranged on the label collecting shaft through a first deep groove ball bearing and a second deep groove ball bearing. The adjusting assembly includes an adjusting nut, a compression spring, and a pressing plate. One end of the label collecting shaft passes through a second pedestal bearing and a spacer sleeve and is connected to the first synchronous belt pulley. The other end passes through the label collecting roller, the pressing plate, and the compression spring in sequence and is threadedly connected to the adjusting nut. The two ends of the compression spring respectively abut between the adjusting nut and the pressing plate. A first friction plate is arranged between the label collecting roller and the pressing plate, and a second friction plate is arranged between the label collecting roller and the second pedestal bearing. The first friction plate and the second friction plate are sleeved on the label collecting shaft. The compression amount of the compression spring is adjusted by rotating the adjusting nut. The adjusting nut may include a first knurled nut and a second knurled nut. By adjusting the first knurled nut and the second knurled nut, the compression amount of the rectangular spring is adjusted, so that the friction force among the first friction plate, the label collecting roller, the second friction plate, and the label collecting shaft changes, and stepless adjustment of the torque of the label collecting roller can be realized. In this way, the pressing rod presses the starting end of the label paper on the label collecting roller. The first synchronous belt pulley rotates, driving the label collecting shaft, the second friction plate, the label collecting roller, the pressing rod, the first friction plate, the pressing plate, the compression spring, the second knurled nut, and the first knurled nut to rotate together, driving the label paper to rotate. The second pedestal bearing is connected to the bearing member.

[0011] A further technical solution is that the label releasing roller assembly includes a transfer shaft, a label releasing roller, a damper, an adjusting piece, and a first pedestal bearing. One end of the transfer shaft is connected to the rotor of the damper, and the other end passes through the first pedestal bearing and is connected to the label releasing roller. The adjusting piece is arranged on the label releasing roller. A fastening nut for locking the label paper is arranged at one end of the transfer shaft where the label releasing roller is arranged. The first pedestal bearing is connected to the bearing member.

[0012] Preferably, there are 3 adjusting pieces, each having 2 U-shaped grooves. By adjusting the relative position of the adjusting pieces on the label releasing roller, the label paper can be clamped tightly. The damper is installed on a Z-shaped plate, and the Z-shaped plate is fixed on the bearing member. By adjusting the movement of the adjusting piece along the U-shaped groove and adjusting to a fixed inner diameter that is exactly the same as the diameter of the label paper, the adjusting piece is fixed on the label releasing roller with screws. The fastening nut is removed, and the label paper is inserted axially along the transfer shaft so that it contacts the 3 adjusting pieces simultaneously and is completely inserted to cover the adjusting pieces without looseness, and then the wing nut is locked. During normal operation, the label paper rotates together with the adjusting piece, the label releasing roller, the transfer shaft, the fastening nut, and the rotor of the damper. Through the damping effect of the damper, a certain rotational damping is provided for the label paper during label releasing.

[0013] A further technical solution is that the driving roller assembly further includes a third bearing with housing, a coupling, a first mounting plate and a second mounting plate. The third bearing with housing is sleeved on the driving roller shaft. The driving member is arranged on the first mounting plate and the second mounting plate. The driving member is a stepping motor. One end of the driving roller shaft is connected to the stepping motor through the coupling. The first mounting plate, the second mounting plate and the third bearing with housing are connected to the bearing member.

[0014] A further technical solution is that the labeling device further includes a first driven roller assembly, a second driven roller assembly and a third driven roller assembly arranged on the bearing member for redirecting the label paper. The first driven roller assembly, the second driven roller assembly and the third driven roller assembly each include a driven roller and a driven roller shaft. The driven roller shaft is connected to the bearing member. The driven roller is arranged on the driven roller shaft. The first driven roller assembly is arranged between the label releasing roller assembly and the driving roller assembly. The second driven roller assembly and the third driven roller assembly are arranged between the label stripping assembly and the label collecting roller assembly.

[0015] A further technical solution is that the vertical guiding member includes a first connecting shaft and a second connecting shaft arranged in parallel. The first connecting shaft and the second connecting shaft are respectively connected to the fixed seat through a first linear bearing and a second linear bearing. The elastic member includes a first linear spring and a second linear spring. The first linear spring and the second linear spring are respectively sleeved on the first connecting shaft and the second connecting shaft. Both ends of the first linear spring and the second linear spring abut against the fixed seat and the fixed plate.

[0016] A further technical solution is that an adjusting screw is provided on the bearing member through a third mounting plate. The adjusting screw is threadedly connected to the third mounting plate. The pressing roller assembly includes a pressing roller, a pressing shaft and a pressing plate. The pressing roller is arranged on the pressing shaft. One end of the pressing plate is hinged to the bearing member, and the other end is provided with the pressing shaft. By adjusting the adjusting screw, the pressing plate is pushed to rotate, and then the pressure between the pressing roller and the driving roller is changed.

[0017] A further technical solution is that the tension of the synchronous belt is adjusted by a cantilever pin and a tensioning pulley. The cantilever pin passes through the tensioning pulley and is installed on the adjusting plate. The adjusting plate is installed on the bearing member. A housing is provided on the bearing member. The driving components and transmission components behind the bearing member are housed in the housing.

[0018] A further technical solution is that the labeling device includes a controller. A first photoelectric sensor and a second photoelectric sensor are provided on the carrier. The first photoelectric sensor and the second photoelectric sensor are arranged on both sides of the label releasing roller assembly. The first photoelectric sensor is used to emit a photoelectric signal, and the second photoelectric sensor is used to receive the photoelectric signal emitted by the first photoelectric sensor. When the second photoelectric sensor receives the photoelectric signal emitted by the first photoelectric sensor, it feeds back to the host computer, and the controller controls the labeling machine to pause. With this setting, the first photoelectric sensor and the second photoelectric sensor are label paper detection devices. When a new label paper is placed, since the outer diameter of the new label paper on the label releasing roller assembly is relatively large, the light emitted by the first photoelectric sensor is blocked by the label paper. At this time, the textile labeling machine operates normally. When the label paper is almost used up, the diameter of the label paper on the label releasing roller assembly becomes very small, and the light emitted by the first photoelectric sensor is received by the second photoelectric sensor. At this time, the textile labeling machine pauses and needs to replace the new label paper to work normally. The first photoelectric sensor and the second photoelectric sensor are respectively installed on the carrier through the first connecting plate and the second connecting plate.

[0019] To achieve the above object, the present invention also provides a textile labeling method. A visual inspection mechanism for detecting fabric defects and any one of the above-mentioned labeling devices are provided on the rewinder. When the visual inspection mechanism detects a defect on the fabric on the rewinder, it sends a signal to the controller, and the controller sends a pulse signal to the driving member. The driving member rotates a predetermined angle, causing the label paper to fall off, and the pressing roller assembly presses the label onto the fabric.

[0020] Compared with the prior art, the present invention can achieve full-automatic labeling, solve the disadvantages of traditional manual labeling such as eye damage, low efficiency, high missed inspection rate, and high error rate, and integrate visual defect detection, automatic labeling, and automatic rewinding into a systematic integration in combination with the visual inspection mechanism and the rewinder. Based on the visual inspection algorithm, electrical control labeling is used, and the degree of intelligence is high; the present invention integrates visual inspection, labeling, and rewinding together, and the system integration is high.

[0021] The present invention is used for defect labeling. The equipment runs stably, has small vibration, less maintenance cost, and low manufacturing cost; the release, rewinding, and labeling of the label are realized through a single stepping motor, the power is simple and single, and the efficiency is high; the structure is simple, and the friction force of the friction plate, rewinding shaft, and rewinding roller is adjusted by adding a compression spring on the rewinding roller assembly to achieve stepless torque adjustment; the space structure is small, the driving force is single, the structure is compact, and it can be easily integrated into various equipment; it has good applicability, and the pressing force of the pressing roller assembly can be adjusted to better fit the object to be labeled.

[0058] The present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention. In addition, those skilled in the art can make corresponding combinations of the features in the embodiments and in different embodiments in this document based on the description of this document.

[0059] The embodiments of the present invention are as follows, referring to Figures 1 to 10 A labeling device 2 includes a carrier 39 and a label placing roller assembly 20, an active roller assembly 50, a pressure roller assembly 80, a label collecting roller assembly 100, a label stripping assembly and a label pressing roller assembly 60 arranged on the carrier 39, wherein the label placing roller assembly 20 is used to carry label paper 32, the active roller assembly 50 includes an active roller shaft 501, an active roller 502, a second synchronous pulley 504 and a driving member, the driving member is connected to the active roller shaft 501 by transmission, the active roller 502 and the second synchronous pulley 504 are fixedly arranged on the active roller shaft 501, and the pressure roller assembly 80 cooperates with the active roller 502 to adjust the label The friction between the label paper 32 and the active roller assembly 50, the label stripping assembly includes a label stripping plate 33 and a label pressing plate 34, the label stripping plate 33 is provided with a label stripping sharp corner for separating the label 35 from the label paper 32, the label pressing roller assembly 60 includes a fixed seat 604, a fixed plate 609, a label pressing roller 6011, an elastic member, a vertical guide member and an anti-fall seat 601, the fixed seat 604 is fixed on the bearing member 39, the elastic member is arranged between the fixed seat 604 and the fixed plate 609, one end of the vertical guide member is connected to the anti-fall seat 601, and the other end passes through the fixed seat 604 and the elastic member and is connected to the mounting plate, The elastic member applies a downward force to the fixed plate 609, and the label pressing roller 6011 is hinged to the fixed plate 609 through the pressing roller shaft 6010. The label pressing roller 6011 can elastically float vertically along the vertical guide member. The label pressing roller 6011 is arranged above the end of the label removal component. The label collecting roller assembly 100 includes a label collecting shaft 108, a label collecting roller 105, a label pressing rod 101 and a first synchronous pulley 107. The label collecting roller 105 and the first synchronous pulley 107 are fixedly arranged on the label collecting shaft 108. The label pressing rod 101 is arranged on the label collecting roller 105 and is used to press the starting end of the label paper 32 on the label collecting roller 105. The first synchronous pulley 107 is connected to the second synchronous pulley 504 through a synchronous belt 46.

[0060] In the specific application process, such as Figure 1, The label paper 32 is installed on the label releasing roller assembly 20. The starting end of the label paper 32 passes between the driving roller 502 of the driving roller assembly 50 and the pressing roller assembly 80, and then passes between the label stripping plate 33 and the label pressing plate 34. After the label paper 32 bypasses the label stripping corner of the label stripping plate 33, the starting end of the label paper 32 adheres to the label receiving roller 105 of the label receiving roller assembly 100. The label pressing rod 101 presses the starting end of the label paper 32 onto the label receiving roller 105, and it can rotate with the label receiving roller 105 of the label receiving roller assembly 100. When the driving member moves, it drives the second synchronous pulley 504 and the driving roller 502 to rotate, adjusts the pressure between the pressing roller assembly 80 and the driving roller 502, thereby adjusting the friction force between the label paper 32 and the driving roller 502. The label paper 32 is pulled under the action of the friction force, causing the label releasing roller 203 on the label releasing roller assembly 20 to rotate, making the label paper 32 rotate slowly. The rotation of the second synchronous pulley 504 drives the synchronous belt to drive the first synchronous pulley 107 to rotate, thereby driving the label receiving roller 105 and the label pressing rod 101 of the label receiving roller assembly 100 to rotate. Since the starting end of the label paper 32 is pressed by the label pressing rod 101 and the label receiving roller 105, when the label receiving roller 105 rotates, the starting end of the label paper 32 rotates with the label receiving roller 105. When the label receiving roller 105 and the label releasing roller 203 rotate simultaneously, the entire part of the label paper 32 operates. When passing through the label stripping plate 33, passing through the label stripping corner of the label stripping plate 33, the label 35 is separated from the label paper 32, realizing the label stripping process. At this time, the label pressing roller 6011 presses the label 35 onto the object to be labeled under the elastic force of the elastic member.

[0061] The present invention realizes label releasing, label receiving, and label pasting through the driving member, with simple power and high efficiency, and can realize fully automatic labeling, solving the disadvantages of traditional manual labeling such as eye injury, low efficiency, high missed inspection rate, and high error rate.

One end of the label receiving shaft 108 passes through the second seat bearing 106 and the spacer 1014 and is connected to the first synchronous pulley 107. The other end passes through the label receiving roller 105, the pressure plate 109 and the compression spring 104 in sequence and is threadedly connected to the adjusting nut. The two ends of the compression spring 104 are respectively abutted between the adjusting nut and the pressure plate 109. A first friction plate 1010 is provided between the label receiving roller 105 and the pressure plate 109. A second friction plate 1013 is provided between the label receiving roller 105 and the second seat bearing 106. The first friction plate 1010 and the second friction plate 1013 are sleeved on the label receiving shaft 108. The compression amount of the compression spring 104 is adjusted by rotating the adjusting nut. The adjusting nut may include a first knurled nut 102 and a second knurled nut 103. By adjusting the first knurled nut 102 and the second knurled nut 103, the compression amount of the rectangular spring is adjusted, so that the friction force of the first friction plate 1010, the label receiving roller 105, the second friction plate 1013, and the label receiving shaft 108 changes, and the torque of the label receiving roller 105 can be infinitely adjusted. In this way, the label pressing rod 101 presses the starting end of the label paper 32 on the label receiving roller 105, and the first synchronous pulley 107 rotates, driving the label receiving shaft 108, the second friction plate 1013, the label receiving roller 105, the label pressing rod 101, the first friction plate 1010, the pressure plate 109, the compression spring 104, the second knurled nut 103, and the first knurled nut 102 to rotate together, and the pressure drives the label paper 32 to rotate.

By adjusting the movement of the adjusting piece 202 along the U-shaped groove to a fixed inner diameter that is exactly the same as the diameter of the label paper 32, the adjusting piece 202 is fixed on the label releasing roller 203 with screws. Then, the fastening nut 201 is removed, and the label paper 32 is inserted axially along the transfer shaft 206 so that it comes into contact with the three adjusting pieces 202 simultaneously and is completely inserted to cover the adjusting pieces 202 without looseness, and then the wing nut is locked. During normal operation, the label paper 32 rotates together with the adjusting pieces 202, the label releasing roller 203, the transfer shaft 206, the fastening nut 201, and the rotor of the damper 207.

[0070] Based on the above embodiments, in another embodiment of the present invention, as Figure 1 and Figure 11, the labeling device 2 includes a controller. A first photoelectric sensor 31 and a second photoelectric sensor 41 are provided on the carrier 39. The first photoelectric sensor 31 and the second photoelectric sensor 41 are arranged on both sides of the label roll assembly 20. The first photoelectric sensor 31 is used to emit a photoelectric signal, and the second photoelectric sensor 41 is used to receive the photoelectric signal emitted by the first photoelectric sensor 31. After the second photoelectric sensor 41 receives the photoelectric signal emitted by the first photoelectric sensor 31, it feeds back to the host computer, and the controller controls the labeling machine to pause. With such a setting, the first photoelectric sensor 31 and the second photoelectric sensor 41 are label paper detection devices. When a new label paper 32 is placed, since the outer diameter of the new label paper 32 on the label roll assembly 20 is relatively large, the light emitted by the first photoelectric sensor 31 is blocked by the label paper 32. At this time, the textile labeling machine operates normally. When the label paper 32 is almost used up, the diameter of the label paper 32 on the label roll assembly 20 becomes very small, and the light emitted by the first photoelectric sensor 31 is received by the second photoelectric sensor 41. At this time, the textile labeling machine pauses and a new label paper 32 needs to be replaced to work normally. The first photoelectric sensor 31 and the second photoelectric sensor 41 are respectively installed on the carrier 39 by installing on the first connecting plate 30 and the second connecting plate 42.

[0071] To achieve the above object, the present invention also provides a textile labeling method. As Figure 11 and Figure 12 , a visual detection mechanism 1 for detecting cloth defects is provided on the winding machine 3 and the labeling device 2 described in any one of the above. When the visual detection mechanism 1 detects a defect on the cloth on the winding machine 3, it sends a signal to the controller. The controller issues a pulse signal to the driving member, and the driving member rotates a predetermined angle, so that the label paper 32 falls off, and the pressing roller assembly 80 presses the label 35 on the cloth.

[0072] Specifically, an installation seat 36 is provided on the carrier 39, and the labeling device 2 is installed on the winding machine 3 through the installation seat 36.

[0073] Among them, the control process of the PLC communication labeling method is as follows:

[0074] The first step is to check the power-on state of the labeling machine and the inventory state of the label paper 32;

[0075] The second step is to judge whether labeling is required according to the output result of the front-end detection / location / recognition and the labeling standard;

[0076] The third step is to configure the parameters and models of the client and the server;

[0077] The fourth step is to establish a connection between the client and the server;

[0078] In the fifth step, the host computer sends a labeling signal to the labeling machine by writing bit data;

[0079] In the sixth step, the labeling machine sends the current status of label 35 to the host computer. If the labeling is completed, the single-labeling process ends.

[0080] If the stock of label paper 32 is insufficient and labeling cannot be performed, an alarm signal is sent to prompt the replenishment of new label paper 32.

[0081] The control process of the labeling method through IO module communication is as follows:

[0082] In the first step, check the power-on status of the labeling machine and the stock status of label paper 32;

[0083] In the second step, judge whether labeling is required according to the output results of front-end detection / location / recognition and the labeling standard;

[0084] In the third step, configure the parameters of serial port baud rate, data bits, stop bits, and parity bits;

[0085] In the fourth step, the host computer establishes a connection with the serial port;

[0086] In the fifth step, the host computer sends a labeling signal to the labeling machine by writing data;

[0087] In the sixth step, the labeling machine sends the current status of label 35 to the host computer. If the labeling is completed, the single-labeling process ends.

[0088] If the stock of label paper 32 is insufficient and labeling cannot be performed, an alarm signal is sent to prompt the replenishment of new label paper 32.

[0089] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
