[0059] The application will be further described in conjunction with the drawings and embodiments:

[0060] As shown in Figures 1a to 8b , Figure 12 , in order to realize the labeling work of the non-release liner pressure sensitive adhesive label 1, the application provides a non-release liner pressure sensitive adhesive label labeling machine which can be directly or indirectly connected with a printer of the non-release liner pressure sensitive adhesive label, comprising a labeling machine housing, a labeling device arranged in the labeling machine housing, the labeling device comprising a label passage assembly 10 for providing label paper walking, a paper passage assembly 30 for completing label paper forward or backward transmission, and a labeling assembly for completing label paper labeling. The labeling device can further comprise an adjustable quick dismounting hinge 20 connecting the labeling machine and the printer, a waste label winding assembly for winding waste labels, and an electrical connection assembly for realizing electrical connection between the labeling machine and the printer.

[0061] As shown in Figure 2 , the non-release liner pressure sensitive adhesive label 1 comprises a face paper 1-1, a pressure sensitive adhesive layer 1-2, a face paper anti-adhesion layer 1-3, and a radio frequency antenna and chip 1-4. The face paper anti-adhesion layer 1-3 is arranged on the surface of the face paper 1-1 to avoid adhesion during the winding process of the non-release liner pressure sensitive adhesive label surface. The pressure sensitive adhesive layer 1-2 is arranged on the lower side of the face paper 1-1 and on the upper side of the radio frequency antenna and chip 1-4 to connect the radio frequency antenna and chip 1-4 with the face paper 1-1. The radio frequency antenna and chip 1-4 are used for writing and reading radio frequency information.

[0062] In the non-release liner pressure sensitive adhesive label 1, the width of the pressure sensitive adhesive layer 1-2 is smaller than the width of the face paper 1-1 (for example, 3 mm), so that the left and right ends of the pressure sensitive adhesive layer 1-2 are recessed by 1.5 mm relative to the end of the face paper 1-1, avoiding adhesion between the non-release liner pressure sensitive adhesive label 1 and the printer or the labeling machine during the label paper walking process.

[0063] I. Label passage assembly

[0064] As shown in Figures 1a to 4 , the label passage assembly 10 has a whole groove-shaped structure, forming a space for accommodating the installation of components such as the paper passage assembly 30 and label paper walking. Specifically, the label passage assembly 10 comprises a label passage assembly bottom plate 11 and label passage side vertical surfaces 12 arranged on both sides of the label passage assembly bottom plate 11. The inner dimension of the label passage assembly 10 (i.e. the width of the inner surface of the two label passage side vertical surfaces 12) is greater than the width of the non-release liner pressure sensitive adhesive label 1 by 0.5 mm, so that the non-release liner pressure sensitive adhesive label 1 can walk in the label passage assembly 10.

[0065] The label passage side vertical surface 12 is provided with a paper feeding guide groove 12-1 for providing a paper feeding passage. Specifically, two rows of protruding paper feeding guide grooves 12-1 are provided on each of the label passage side vertical surfaces 12, and the distance between the two rows of paper feeding guide grooves 12-1 is 1 mm. In the present application, the protruding height of the paper feeding guide groove 12-1 is 2 mm, and since the left and right ends of the pressure-sensitive adhesive layer 1-2 are recessed by 1.5 mm relative to the end of the face paper 1-1, the pressure-sensitive adhesive layer 1-2 in the release paper-free pressure-sensitive adhesive label 1 does not come into contact with the paper feeding guide groove 12-1, so that the release paper-free pressure-sensitive adhesive label 1 can smoothly advance / retract along the paper feeding guide groove 12-1.

[0066] The label passage assembly base plate 11 is provided with a limiting ridge 11-1 for mounting a motor and a guide wheel, so as to realize the mounting and fixing of the paper feeding passage assembly 30 and the like. The end of the label passage assembly 10 is provided with a label sticking pressure wheel 14, which is in contact with luggage and the like, so as to realize accurate label sticking when the label sticking pressure wheel 14 rolls on the luggage and the like.

[0067] Figure 4 The working principle of the paper guiding disc 13 in the present application is shown in the figure. In order to smoothly feed the label paper 1 into the paper feeding guide groove 12-1, the inner width of which is only 1.5 mm, the paper feeding guide disc 13 is needed to guide the label paper 1 into the paper feeding guide groove 12-1. The paper feeding passage of the paper feeding guide disc 13 is in a horizontal triangle shape, the width of the inlet is 6-8 mm, the width of the outlet is 1 mm, the outlet is connected with the paper feeding guide groove 12-1, the width of the paper outlet is 1 mm, and the width of the opposite end is 1.5 mm. The label paper 1 first enters the 6-8 mm wide inlet of the paper feeding disc, and then passes through the 1 mm wide paper feeding disc to smoothly enter the 1.5 mm wide paper feeding guide groove 12-1.

[0068] II. Adjustable quick-release hinge

[0069] As shown in Figure 1a , Figures 5a to 6 , in order to realize the direct connection of the release paper-free pressure-sensitive adhesive label sticking machine with the printer and realize the position adjustment of the release paper-free pressure-sensitive adhesive label sticking machine, the front end of the label passage assembly 10 is provided with an adjustable quick-release hinge 20, which is used to realize the quick release and position adjustment with the printer.

[0070] The adjustable quick-release hinge 20 is composed of a hinge fixing part 21 and a hinge rotating part 25. The top end of the rotating shaft hole of the hinge fixing part 21 is provided with an adjusting screw 24 which can be adjusted left and right. The adjusting screw 24 is made of iron and can be attracted by a magnet. The hinge fixing part 21 is fixed on the front end panel of the printer through the hinge fixing part screw hole 23.

[0071] The rotating part screw hole 25-1 of the hinge rotating part 25 center is embedded with the hinge rotating shaft 26, which is made of iron, and the front end of the hinge rotating shaft 26 is bonded and fixed with the rotating shaft magnet 27 (permanent magnet). The rotating part screw hole 25-1 is fixed on the labeling channel assembly 10, and the two become one, the hinge rotating shaft 26 is inserted into the rotating shaft hole of the hinge fixed part 21, the rotating shaft magnet 27 at the front end of the hinge rotating shaft 26 is attracted together with the adjusting screw 24 of the hinge fixed part 21, the hinge fixed part 21 and the hinge rotating part 25 are connected together, and the hinge rotating shaft 26 can rotate in the rotating shaft hole. By entering or retreating the adjusting screw 24, the hinge rotating shaft 26 is pushed or pulled to move left and right, and the left and right positions of the label channel assembly 10 are changed.

[0072] If the hand holds the hinge rotating part 25 or the label channel assembly 10 moves outwardly, the force is greater than the attraction force of the adjusting screw 24 and the rotating shaft magnet 27 at the front end of the rotating shaft, and the two are pulled apart, the hinge rotating part 25 and the label channel assembly 10 are separated from the printer, and the quick disassembly is realized. If the hinge rotating shaft 26 is inserted into the shaft hole of the hinge fixed part 21, the attraction force of the rotating shaft magnet 27 and the adjusting screw 24 fixes the hinge rotating part 25 and the label channel assembly 10 on the printer.

[0073] A downward hinge angle adjusting plate 28 is fixed near the front end of the hinge rotating part 25, and an angle adjusting adjusting screw 29 is provided on the hinge angle adjusting plate 28, the front end of the angle adjusting adjusting screw 29 is in contact with the front end panel of the printer, the distance between the hinge angle adjusting plate 28 and the front panel of the printer is changed by advancing or retreating the angle adjusting adjusting screw 29, so as to push the hinge rotating part 25 to rotate, and the hinge rotating part 25 drives the label channel assembly 10 to change the angle with the front end panel of the printer.

[0074] Three, paper feeding channel assembly

[0075] As shown in Figure 1a , Figure 1b , Figures 7a to 8b , the paper feeding channel assembly 30 includes a paper feeding sensor 31, a paper feeding power motor and a rubber wheel 32, a middle power motor and a rubber wheel 33, a labeling power motor and a rubber wheel 34, and a paper feeding to position sensor 35. Among them, the paper feeding power motor and the rubber wheel 32, the middle power motor and the rubber wheel 33, the labeling power motor and the rubber wheel 34 all include corresponding power motor, rubber wheel connected with power motor, power motor floating plate installing power motor and rubber wheel, power motor floating plate rotating shaft arranged on power motor floating plate and corresponding to power motor position, and anti-sticking bottom wheel corresponding to rubber wheel position. In the implementation process, the power motor, the rubber wheel drives the power motor floating plate to rotate around the power motor floating plate rotating shaft under its own gravity and presses the non-separable bottom paper pressure-sensitive adhesive label 1.

[0076] The paper feeding sensor 31 is located at the paper feeding end of the label passage assembly 10. The paper feeding power motor and rubber wheel 32 is also located at the paper feeding end of the label passage assembly 10, which includes a paper feeding power motor and a paper feeding rubber wheel. The paper feeding power motor is a double-shaft direct current micro motor, and the two shafts of the micro motor are respectively provided with corresponding paper feeding rubber wheels. The paper feeding power motor is fixed on the paper feeding power motor floating plate 32-1, and the paper feeding power motor floating plate shaft 32-2 on the paper feeding power motor floating plate 32-1 is more than 120 mm away from the paper feeding power motor. The paper feeding power motor relies on its own gravity to swing downward around the paper feeding power motor floating plate shaft 32-2, so that the paper feeding rubber wheel is pressed on the paper feeding anti-adhesion bottom wheel 32-3.

[0077] The middle power motor and rubber wheel 33 is located at the middle position of the label passage assembly 10, which includes a middle power motor and a middle rubber wheel. The middle power motor is fixed on the middle power motor floating plate 33-1, and the middle power motor floating plate 33-1 is rotatably connected to the shell of the labeling machine through the middle power motor floating plate shaft 33-2. The middle power motor relies on its own gravity to swing downward around the middle power motor floating plate shaft 33-2, so that the middle rubber wheel is pressed on the middle anti-adhesion bottom wheel 33-3.

[0078] The paper feeding sensor 31 is located at the paper feeding end of the label passage assembly 10. The paper feeding power motor and rubber wheel 32 is also located at the paper feeding end of the label passage assembly 10, which includes a paper feeding power motor and a paper feeding rubber wheel. The paper feeding power motor is fixed on the paper feeding power motor floating plate 32-1, and the paper feeding power motor floating plate 32-1 is rotatably connected to the shell of the labeling machine through the paper feeding power motor floating plate shaft 32-2. The paper feeding power motor relies on its own gravity to swing downward around the paper feeding power motor floating plate shaft 32-2, so that the paper feeding rubber wheel is pressed on the paper feeding anti-adhesion bottom wheel 32-3.

[0079] The line speeds of the above-mentioned paper feeding rubber wheel, middle rubber wheel and labeling rubber wheel are all greater than the printing and paper feeding speed of the printer, and the line speeds of the paper feeding rubber wheel, middle rubber wheel and labeling rubber wheel gradually increase, which cooperates with the paper feeding power motor floating plate 32-1, middle power motor floating plate 33-1 and labeling power motor floating plate 34-1 to make the respective motors rely on their own weight to press on the corresponding anti-adhesion bottom wheel, and the pressure is small and the floating is floating. The label paper is pulled forward, and the label paper will not bend and droop.

[0080] In the implementation process of the paper feeding passage assembly 30:

[0081] (1) In the forward process:

[0082] a. When the paper feeding sensor 31 senses that the label paper enters, the paper feeding signal is input to the paper feeding motor control circuit board, and the paper feeding power motor is controlled to rotate forward --- to rotate downward;

[0083] b. The front edge of the label paper contacts the paper feeding rubber wheel, and under the driving of the downward rotation of the paper feeding rubber wheel, enters between the paper feeding rubber wheel and the paper feeding anti-sticking bottom wheel 32-3. Under the driving of the rotation of the paper feeding rubber wheel, the label paper runs, enters the guide disc 13 through the large-diameter position, and exits through the small-diameter position, and smoothly enters the paper running guide groove 12-1;

[0084] c. When the label paper driven by the paper feeding power motor runs through the middle position of the label passage assembly 10, the label paper enters between the middle rubber wheel and the middle anti-sticking bottom wheel 33-3, and the rotation of the middle rubber wheel drives the label paper to run forward.

[0085] d. When the label paper runs through the paper outlet end of the label passage assembly 10, it enters between the labeling rubber wheel and the labeling anti-sticking bottom wheel 34-3, and runs forward under the driving of the rubber roller.

[0086] (2) When moving to the position:

[0087] When the label paper reaches the position of the paper feeding to position sensor 35, the output of the paper feeding to position sensor 35 closes the power output of the paper feeding motor control line board, the paper feeding power motor, the middle power motor and the labeling power motor stop moving, and the label paper stops in the paper feeding passage assembly 30;

[0088] A anti-sticking module is arranged at the paper outlet end of the label passage assembly 10, the height of the anti-sticking module is 1.5mm lower than the center line of the paper running guide groove 12-1, and the top of the anti-sticking module is a anti-sticking functional layer which will be adhered to the pressure-sensitive adhesive layer of the label paper.

[0089] Four, labeling assembly

[0090] The existing label printer does not issue a labeling instruction, but the labeling instruction is issued by an airline baggage check-in computer or a cargo conveying device. However, due to the complexity of the labeling scene composed of the printer, the labeling machine, the luggage and the conveying belt, it is very inconvenient to transmit the labeling instruction by cable, and therefore the present application adopts infrared wireless transmission of the labeling instruction.

[0091] Specifically, the labeling assembly comprises an infrared labeling instruction receiver 41 and a labeling completion identification sensor 42. The infrared labeling instruction receiver is located at the top of the highest part of the shell of the labeling machine, and is used to receive the labeling instruction and drive the rotation of each power motor to drive the forward or backward movement of the non-release bottom paper pressure-sensitive adhesive label 1. The labeling completion identification sensor 42 is used to identify the labeling completion state.

[0092] In the labeling process: the labeling pressure roller 14 is in contact with the luggage (cargo) commodity in front of it and rotates, under the drive of the labeling pressure roller 14, the label paper enters between the labeling pressure roller 14 and the luggage (cargo), and the pressure-sensitive adhesive layer of the label paper is bonded to the surface of the luggage (cargo). Before the label paper labels forward, when the tail end of the label paper labels forward leaves the labeling completion identification sensor 42, the labeling completion identification sensor 42 signal is transmitted to the middle power motor control circuit board, the labeling power motor is turned off, and the label paper is completely labeled on the luggage (cargo) under the drive of the labeling pressure roller 14.

[0093] Five, waste label winding assembly

[0094] As shown in Figure 1a , Figure 1b , the waste label winding assembly includes a waste label paper feeding upper pressure roller 51, a waste label winding paper tube 53, a waste label winding upper cover 54, a winding pressure roller 55, a waste label winding completion sensor 56, and a waste label winding limit alarm sensor 57. The returned waste label is wound on the waste label winding paper tube 53 after passing through the waste label paper feeding upper pressure roller 51 and the winding pressure roller 55, and the waste label winding completion sensor 56 and the waste label winding limit alarm sensor 57 are arranged on the waste label winding upper cover 54.

[0095] Similar to the structure of the paper feeding power motor and the rubber roller 32, the waste label paper feeding upper pressure roller 51 is fixed on the waste label paper feeding pressure roller floating plate 51-1, the waste label paper feeding pressure roller floating plate 51-1 is rotationally connected to the waste label winding upper cover 54 through the waste label paper feeding pressure roller floating plate rotating shaft 51-2, and the waste label winding motor (not shown in the figure) and the waste label paper feeding upper pressure roller 51 swing downward around the waste label paper feeding pressure roller floating plate rotating shaft 51-2 by relying on their own gravity, so that the waste label paper feeding upper pressure roller 51 is pressed on the paper feeding power motor and the rubber roller 32. The pressure of the waste label paper feeding upper pressure roller 51 is small, the pulling force of the label paper is less than the paper feeding drag force of the printer, the linear speed of the waste label paper feeding upper pressure roller 51 is greater than the speed of the paper feeding of the printer, and the pulling force of the waste paper tube is very small. The actual rotation speed of the waste label winding follows the paper feeding speed of the printer, which ensures that there is no sinking and wrinkling in the waste label winding and does not affect the normal work of the printer.

[0096] The waste label winding motor control board receives the waste label instruction sent by the printer and starts the waste label collection process:

[0097] a. The waste label winding motor control board controls the paper feeding power motor to reverse --- rotate upward, the waste label coming out of the printer collides with the upward rotating paper feeding rubber roller and goes upward with it, enters between the paper feeding rubber roller and the waste label paper feeding upper pressure roller 51, and the paper feeding power motor drives the waste label to forward;

[0098] b.The waste label winding motor control board also drives the forward power motor and rubber wheel 52-1 forward rotation, the rear power motor and rubber wheel 52-2 reverse rotation, which drives the waste label winding paper tube 53 to rotate, and the waste label in front collides with the rotating waste label winding paper tube 53 and runs following, and the pressure-sensitive adhesive on the bottom of the waste label is adhered to the waste label winding paper tube 53, and the waste label is wound up through the winding pressure roller 55.

[0099] c.When the tail end of the waste label passes through the waste label winding completion sensor 56, the waste label winding completion sensor 56 outputs a signal to the waste label winding motor control board, and the power is turned off and the waste label winding is completed.

[0100] With the progress of the waste label winding process, the outer diameter of the waste label winding paper tube 53 increases with the increase of the number of waste label winding, and when the outer diameter is large to a certain range, the waste label winding limit alarm sensor 57 is triggered, the waste label winding alarm is triggered, and the staff is notified by sound and light to take down the waste label roll and put a new waste label winding paper tube 53.

[0101] The winding pressure roller 55 is fixed on the waste label winding upper cover 54, and the other end of the waste label winding upper cover 54 is connected with the waste label winding pressure roller floating plate rotating shaft 51-2, so that the waste label winding upper cover 54 and the winding pressure roller 55 can swing up and down, and when the outer diameter of the waste label winding paper tube 53 increases, the pressure of the winding pressure roller 55 is not affected, and the waste label winding is ensured to proceed smoothly.

[0102] Six, electrical connection assembly

[0103] The electrical connection assembly is used to realize the electrical connection of the non-release base paper pressure-sensitive adhesive label applicator and the printer. In other embodiments, the electrical connection assembly can also be connected with other electrical structures.

[0104] The paper outlet end of the printer is provided with a magnetic terminal block seat, which includes at least five contact points: power +, power -, label output signal end, waste label signal end, and label applicator fault signal end. The magnetic terminal block of the non-release base paper pressure-sensitive adhesive label applicator corresponds to the magnetic terminal block seat, and is connected with the control board in the label applicator through wires.

[0105] The waste label signal has priority control right, drives the waste label winding program to start, and puts the printer in a fault state through the label applicator fault signal end, so that the printing program cannot be entered, and the printed label is prevented from being sent into the label applicator with fault.

[0106] The present application realizes the complete labeling process of the non-release base paper pressure-sensitive adhesive label:

[0107] 1, install the label applicator on the printer

[0108] The hinge rotating shaft 26 of the labeling machine is inserted into the hinge shaft hole of the printer paper outlet end and magnetically connected with the adjusting screw 24 to achieve quick installation. Thereafter, the magnetic connection plate of the labeling machine is aligned with the magnetic connection plate seat of the printer, and the two are attracted together to complete the electrical connection.

[0109] 2. Adjust the left and right positions and the inclination angle of the labeling machine

[0110] First, turn the adjusting screw 24 to make the inclination angle of the labeling machine meet the requirements.

[0111] Second, turn the angle adjusting screw 29 to change the left and right positions of the labeling machine, so that the left and right positions of the printer paper outlet align with the position of the paper guide groove 12-1 of the labeling machine, ensuring that the label paper accurately enters the paper guide groove 12-1.

[0112] 3. Label paper entering the labeling machine and anti-sticking

[0113] (1) Working principle of labeling machine anti-sticking:

[0114] a. The groove depth of the paper guide groove 12-1 in the label channel assembly 10 is 1.5 mm. Since the width of the pressure-sensitive adhesive layer in the non-release backing paper pressure-sensitive adhesive label 1 is inwardly recessed by 2 mm on both sides, the label paper in the paper guide groove 12-1 has no pressure-sensitive adhesive layer and will not stick.

[0115] b. In the paper feed channel assembly 30, the paper feed rubber wheel, the middle rubber wheel, the labeling rubber wheel, and the paper feed anti-sticking bottom wheel 32-3, the middle anti-sticking bottom wheel 33-3, and the labeling anti-sticking bottom wheel 34-3 are all anti-sticking wheels that support the pressure-sensitive adhesive layer of the label but will not stick to it.

[0116] (2) Label paper feeding principle:

[0117] As shown in Figure 1a , Figure 1b , Figure 9 , the label paper enters the labeling machine from the printer, and the label paper is subjected to the tensile force of the printer paper outlet, the tensile force between the paper feed anti-sticking bottom wheel 32-3 and the paper feed motor, the tensile force between the middle anti-sticking bottom wheel 33-3 and the middle motor, and the tensile force between the labeling anti-sticking bottom wheel 34-3 and the labeling motor.

[0118] Because the paper feeding power motor cooperates with the paper feeding power motor floating plate 32-1, the middle power motor cooperates with the middle power motor floating plate 33-1, and the labeling power motor cooperates with the labeling power motor floating plate 34-1, and the pressure of each power motor on the corresponding anti-sticking bottom wheel is small, the anti-tension of the printer output label >> the tension of the paper feeding power motor and the rubber wheel 32 > the tension of the middle power motor and the rubber wheel 33 > the tension of the labeling power motor and the rubber wheel 34, so the labeling machine does not affect the normal work of the printer. And through the corresponding power motor floating plate, the automatic adjustment of the tension and speed of each position is realized.

[0119] The speed relationship of the three power motors feeding paper when labeling is: the linear speed of the paper feeding power motor < the linear speed of the middle power motor < the linear speed of the labeling power motor, which ensures that the label paper always receives forward tension in the labeling machine and does not bend and sag in the labeling machine, and does not stick to the labeling machine.

[0120] When the printer is started, the printed label paper is recognized by the paper feeding sensor 31 when it enters the labeling machine, and all the power motors are driven to rotate. The label paper coming out of the printer collides with the paper feeding power motor and the rubber wheel 32, the paper feeding rubber wheel rotates downward, driving the label paper downward into the paper feeding rubber wheel and the paper feeding anti-sticking bottom wheel 32-3, through the guide disc 13 into the paper feeding guide slot 12-1, and then through the middle power motor and the rubber wheel 33, the labeling power motor and the rubber wheel 34, to the position of the paper feeding in-place sensor 35. The output of the paper feeding in-place sensor 35 turns off all the power motors, and the label paper stops in the labeling machine.

[0121] 3. Label paper labeling process

[0122] As shown in Figure 1a , Figure 10 , the infrared labeling instruction receiver 41 of the labeling assembly receives the labeling instruction and sends out the labeling instruction, and drives the labeling power motor and the rubber wheel 34 to drive the label paper to move forward. Because the labeling pressure roller 14 is in contact with the luggage and cargo, it rotates under the forward movement of the luggage and cargo, and the label paper moves forward and collides with the downward rotating labeling pressure roller 14, and then moves downward, enters between the labeling pressure roller 14 and the forward moving luggage and cargo, and under the pressure of the labeling pressure roller 14, the label paper is pasted on the luggage and cargo.

[0123] Because the adhesive tension of the label paper pasted on the luggage and cargo is large, and the speed of the luggage and cargo is much greater than the linear speed of the labeling rubber roller and the middle rubber roller in the labeling machine, after the label paper is pasted on the luggage and cargo, the speed of the label paper is consistent with the speed of the luggage and cargo.

[0124] Since the middle power motor is connected with the middle power motor floating plate 33-1 and the labeling power motor is connected with the labeling power motor floating plate 34-1, the middle power motor floating plate 33-1 and the labeling power motor floating plate 34-1 are lifted under the pulling of the label paper, the middle power motor and the labeling power motor lose the function of transmitting the label paper, and the label paper is driven by the luggage and the goods under the pressure of the labeling pressure wheel 14 to complete the labeling process.

[0125] When the tail end of the label paper reaches below the labeling completion recognition sensor 42, the output of the labeling completion recognition sensor 42 turns off the power supply of the labeling power motor and the rubber wheel 34, and the label paper is driven by the labeling pressure wheel 1414 to complete the labeling.

[0126] 5, waste label winding

[0127] Since the success rate of writing of the radio frequency label cannot be 100%, there may be invalid waste labels, and the waste labels must not be pasted on the luggage and goods, and the printer can automatically check the quality of the label and print a mark on the waste label so as to be collected and thrown away by the user.

[0128] As shown in Figure 1a , Figure 1b , Figure 9 The printer of the present application has the function of automatically winding the waste label.

[0129] The printer recognizes the unqualified label and sends a waste label information instruction to the labeling machine. After receiving the waste label instruction, the labeling machine preferentially controls the reverse rotation of the paper feeding power motor and the rubber wheel 32 to drive the label paper to enter between the waste label paper feeding upper pressure wheel 51 and the paper feeding rubber wheel, and drive the waste label to move forward. The waste label information instruction drives the forward power motor and the rubber wheel 52-1 of the waste label winding paper tube 53 to rotate forward, and the rear power motor and the rubber wheel 52-2 to rotate reversely, and then drives the waste label winding paper tube 53 to rotate. The waste label collides with the rotating waste label winding paper tube 53, and the pressure-sensitive adhesive layer thereof contacts the waste label winding paper tube 53, and under the pressure of the winding pressure wheel 55, the waste label is wound on the waste label winding paper tube 53. When the tail end of the waste label reaches the position of the waste label winding completion sensor 56, the output of the waste label winding completion sensor 56 turns off the power motor participating in the waste collection, and the waste label winding is completed.

[0130] When there are multiple waste labels on the waste label winding paper tube 53, the outer diameter thereof increases and touches the waste label winding limiting alarm sensor 57, and the output of the waste label winding limiting alarm sensor 57 drives the alarm to emit an audible and visual signal to inform the staff to replace the waste label winding paper tube 53. The waste label winding upper cover 54 is lifted by hand, the waste label winding paper tube 53 with multiple waste labels is removed, a new waste label winding paper tube 53 is replaced, and then the waste label winding upper cover 54 is put down. When non-radio frequency labels are used for labeling, the waste label winding assembly can be removed.

[0131] 6. Self-test of malfunction---to prevent the printer from feeding labels into the labeling machine

[0132] Because the pressure-sensitive adhesive layer of the no release liner pressure-sensitive adhesive label 1 is exposed, if the label paper leaves the paper guide slot 12-1, it may be bonded and accumulated in the label passage assembly 10, causing the labeling machine to malfunction and not work normally.

[0133] The label paper enters the labeling machine passage first through the paper feed sensor 31 and finally stops at the paper feed in-place sensor 35. Since the distance from the paper feed sensor 31 to the paper feed in-place sensor 35 is the length of the label paper plus 30 mm: if the length of the airline baggage label is 220 mm, the distance between the paper feed sensor 31 and the paper feed in-place sensor 35 is 250 mm, and with the fastest paper output speed of the printer being 130 mm per second, the time for the label paper to travel from the paper feed sensor 31 to the paper feed in-place sensor 35 will not be more than 3 seconds. If this time exceeds 3 seconds, the labeling machine will issue an audible and visual alarm and output a fault signal to the printer, causing the printer to enter a standby state. If the length of the express logistics label or commodity label is less than 130 mm, the fault test window is changed to 2 seconds.

[0134] As shown in Figures 11a to 11c the working principle of the self-test of the present application is:

[0135] The paper feed sensor 31 outputs a pulse t1 to open the electronic switch, and the output T of the electronic switch opens the gate, the input of which is t1, and the output t2 of the paper feed in-place sensor 35 closes the electronic switch, i.e. closes the gate, because the time of t1 and t2 is less than 3 seconds, so the signal of t1 delayed for 3 seconds will not pass through the gate.

[0136] If there is pressure-sensitive adhesive bonding in the labeling machine, the paper feed in-place sensor 35 cannot detect the arrival information of the label, because there is no t2 signal, so the gate cannot be closed, and the pulse of t1 delayed for 3 seconds becomes a fault alarm signal to the printer, informing the printer not to input labels into the labeling machine.

[0137] The present application can be applied to: no release liner baggage label automatic printing and automatic labeling (aviation industry), no release liner ordinary express label / express radio frequency label automatic printing and automatic labeling (express and logistics transportation industry), no release liner cold storage label automatic printing and automatic labeling (commercial industry), etc.

[0138] Analysis of the economic value of the application of the present application:

[0139] 1. No release liner airline baggage label automatic printing and automatic labeling

[0140] The application changes the operation mode of the airline check-in, and upgrades the traditional manual luggage label to the automatic printing and automatic label pasting type luggage label without manual operation. The application reduces the airport check-in personnel, accelerates the check-in efficiency, and enables the passengers to enjoy the relaxed and fast travel.

[0141] In addition, since the automatic printing and automatic label pasting type luggage label reduces the length by half, according to the annual use of 100 million luggage labels, the cost is saved by about 10 million yuan RMB.

[0142] 2. The annual use of express industry exceeds 100 billion express labels, and the number of label printers is 5 million. 30% of the label printers adopt automatic printing and automatic label pasting, and 1.5 million manual workers can be saved.

[0143] 3. The automatic label pasting type without release paper can save 104 million square meters of release paper for the express industry every year, which is equivalent to 62.4 thousand tons, low carbon, environmental protection and low cost.
