Abstract
Description
Technical Field
[0001] This invention relates to the field of labeling machine technology, and more particularly to an automatic labeling machine. Background Technology
[0002] The operating logic of existing traditional labeling mechanisms is as follows:
[0003] When the sensor sends a signal that the object to be labeled is ready for labeling, the drive wheel on the labeling machine rotates. Since the roll of labels is tensioned on the device, as the backing paper changes direction while adhering tightly to the peel plate, the label, due to its inherent rigidity, is forced to detach at the front end, ready for labeling. At this moment, the object to be labeled is positioned directly beneath the label, and synchronous labeling is achieved under the action of the labeling wheel. After labeling, the sensor beneath the roll of labels sends a stop signal, the drive wheel stops, and one labeling cycle is complete.
[0004] Existing traditional labeling institutions peel off the labels from the incoming roll of material, then pick up the labels and attach them to the product. The back of the incoming roll of material is continuously connected, while the labels are separated by gaps, thus realizing continuous label peeling, picking up, and labeling operations.
[0005] However, existing traditional labeling methods are not suitable for the current network access license labels. Network access license labels are continuously printed paper labels, with each page connected at discontinuous points. Traditional labeling structures require tensioning the backing paper, which can easily cause breakage during continuous printing. Furthermore, each label layer is connected at discontinuous points, with sticker separators between layers. These sticker separators can easily cause jamming when peeling off the label to insert it onto the anti-stick block. Summary of the Invention
[0006] This invention provides an automatic labeling machine that solves the technical problems of existing traditional labeling mechanisms being unsuitable for automatic labeling of continuously printed paper labels, having low labeling efficiency, and suffering from tension breakage and material jamming.
[0007] To solve the above technical problems, the present invention provides an automatic labeling machine, which is equipped with a cabinet. A labeling module is installed at one end of the top surface of the cabinet, and a label peeling module and a transport module are installed at the other end. The transport module is installed in front of the labeling module. The label peeling module includes a feeding component, a label peeling component, and a receiving component. The label peeling component is installed on one side of the end of the feeding component, and the receiving component is arranged below the end of the feeding component.
[0008] When the label peeling component senses that the feeding component has transported the label to be peeled to the peeling position, the label peeling component first rises and then presses down to press and bend the backing paper of the label to be peeled downwards. Under the continuous pushing of the feeding component, the label sticker on the label to be peeled separates from the backing paper and moves horizontally to the top surface of the label peeling component. At the same time, the receiving component clamps the backing paper and receives it downwards.
[0009] The transport module transports the products to be labeled to the area below the labeling module;
[0010] The labeling module picks up the label sticker from the top surface of the peeling component and moves it to the labeling area of the product to be labeled.
[0011] This basic solution addresses the characteristics of continuous printing paper labels with broken connections by setting up targeted feeding, peeling, and receiving components. The feeding component provides horizontal feeding, while the peeling component first rises and then presses down to compress and bend the backing paper of the label to be peeled. Under the continuous pushing of the feeding component, the label sticker on the label to be peeled separates from the backing paper (separating the broken sticker onto the backing paper, which directly enters the waste collection, thus avoiding jamming) and moves horizontally to the top of the peeling component. At the same time, the receiving component clamps the backing paper and vertically collects it downwards. This satisfies the separation and pickup of label stickers on continuously printed paper labels and avoids breakage and jamming caused by tensioning. A transport module is configured to realize the automatic positioning and transport of the product to be labeled, which cooperates with the label picking and pasting of the labeling module to improve labeling efficiency and labeling accuracy.
[0012] In a further embodiment, the feeding assembly includes a base plate and a frame, a limiting seat, a first guide roller group, and a second guide roller group mounted on the base plate:
[0013] The frame includes a first platform, a second platform, and a mounting bracket mechanically connected. The limiting seats are installed on both sides of the top surface of the first platform, and the middle part is used to place the label to be peeled off. The mounting bracket includes a first vertical plate and a second vertical plate respectively disposed on both sides, and a crossbeam connecting the first vertical plate and the second vertical plate. The bottom of the first vertical plate and the second vertical plate are installed on the base plate, and the first platform, the first guide roller group, the second platform, and the second guide roller group are sequentially installed in the middle part, and the crossbeam is installed on the top part.
[0014] The first platform and the second platform are at the same horizontal level.
[0015] This solution sets up a frame to install and fix the limiting seat, the first guide roller group, and the second guide roller group. The limiting seat defines the label placement area on the first platform, thereby achieving precise positioning of the label to be peeled off. The first guide roller group is inserted between the first and second platforms, and the first guide roller group is used to apply movement power to the label to be peeled off. The second guide roller group is set at the end of the second platform to clamp and peel off the backing paper of the label in conjunction with the peeling action, thereby automating the separation of the backing paper and the label sticker.
[0016] In a further embodiment, the first guide roller assembly includes a first driving roller, a first driven roller, and a first motor;
[0017] The first drive roller is installed between the first platform and the second platform and is lower than the horizontal height of the first platform. One end of the roller is rotatably installed on the first vertical plate, and the other end is rotatably installed on the second vertical plate. It is also rotatably connected to the first motor via a belt.
[0018] The first driven roller is mounted above the first driving roller and at a height higher than the first platform, with its two ends rotatably mounted on the first vertical plate and the second vertical plate, respectively.
[0019] The first motor is installed in the inner cavity of the mounting bracket, and its rotating end passes through the second vertical plate and is rotatably connected to the first drive roller via a belt.
[0020] The label to be peeled is placed on the first platform and inserted between the first active roller and the first driven roller. The first active roller rotates under the drive of the first motor, which in turn drives the first driven roller to rotate, thereby moving the label to be peeled toward the second platform.
[0021] This solution sets up a symmetrical first active roller and a first driven roller between the first platform and the second platform. The first active roller is driven by the first motor to move the labels to be peeled toward the second platform. At the same time, the first driven roller below rotates synchronously under friction, so that a whole row of labels to be peeled can move stably and be evenly stressed. Furthermore, the use of friction for movement control can effectively avoid breakage caused by tension.
[0022] In a further embodiment, the second guide roller assembly includes a second driving roller, a second driven roller, and a second motor;
[0023] The second drive roller is installed at the end of the second platform and is horizontal at the same height as the second platform. One end of the roller is rotatably installed on the first vertical plate, and the other end is rotatably installed on the second vertical plate. It is also rotatably connected to the second motor via a belt.
[0024] The second driven roller is mounted above the second platform, with its two ends rotatably mounted on the first vertical plate and the second vertical plate, respectively;
[0025] The second motor is installed inside the mounting bracket, and its rotating end passes through the second vertical plate and is rotatably connected to the second drive roller via a belt;
[0026] After the label to be peeled enters the second platform, it is inserted between the second driven roller and the second platform. The second active roller rotates under the drive of the second motor. At this time, the label peeling component senses that the label to be peeled has been transported to the peeling position. The label peeling component first rises and then presses down to press and bend the backing paper of the label to be peeled downward. The label sticker on the label to be peeled separates from the backing paper and moves horizontally to the top surface of the label peeling component. At the same time, the backing paper is displaced into the receiving component under the drive of the second active roller.
[0027] This solution features a second driven roller rotatably connected to the top surface of the second platform, which continuously presses the label to be peeled towards the labeling module to prevent the front end of the label from lifting up. A second active roller is installed below the end of the second platform to provide downward power for the separated bottom paper, which, together with the receiving component, directionally recycles the bottom paper downwards, thus automating waste recycling.
[0028] In a further embodiment, the receiving assembly includes an inner guide plate, an outer guide plate, a first tension roller, a second tension roller, a tensioning seat, and a tensioning cylinder; the rear end of the tensioning seat is installed at the end of the telescopic rod of the tensioning cylinder, and the front end is rotatably mounted with the first tension roller; the second tension roller is rotatably mounted on the frame, with its outer side close to the first tension roller and directly below the second drive roller;
[0029] The inner guide plate is vertically mounted on the frame, with its top close to the second platform and its bottom facing the gap between the first tension roller and the second tension roller.
[0030] The outer guide plate is vertically installed on the end face of the frame, with its top close to the outside of the second drive roller and its bottom facing the gap between the first tension roller and the second tension roller.
[0031] The bottom paper is displaced downwards by the second drive roller and enters the gap between the first tension roller and the second tension roller through the inner guide plate and the outer guide plate. At this time, the tensioning cylinder works to drive the first tension roller on the tensioning seat to move closer to the second tension roller, so that the first tension roller and the second tension roller clamp the bottom paper. The second drive roller applies a downward force to the bottom paper, driving the first tension roller and the second tension roller to rotate, thus completing the directional collection of the bottom paper.
[0032] Based on the size characteristics of continuously printed paper labels, this solution sets up inner and outer guide plates that cooperate with each other to guide the bottom paper, so that the bottom paper accurately enters the gap between the first and second tension rollers. At this time, the cylinder drives the first tension roller to approach the second tension roller to clamp the bottom paper, which can effectively prevent the bottom paper from being freely conveyed and complete the automatic material collection action.
[0033] In a further embodiment, the label peeling assembly includes a lifting frame, a lifting cylinder, a fixed base, an anti-sticking block, a pressure roller, a bending cylinder, and a fiber optic sensor. The lifting cylinder is installed in the middle of the back of the fixed base, and the anti-sticking block is installed on the top. The lifting frame is installed on both sides of the lifting cylinder, and the bottom of the lifting cylinder and the lifting frame are fixed to the cabinet.
[0034] The anti-stick block has recessed ends to form mounting positions and extends backward in the middle to form placement positions. Several through-plate detection ports are provided on the placement positions. The fiber optic sensor is installed below the detection ports.
[0035] The two sets of bending cylinders are installed in the mounting position, with their telescopic rods facing rearward and fixed blocks installed on them;
[0036] The two ends of the pressure roller are rotatably mounted on the fixed block via bearings, with its top close to the placement position;
[0037] When the fiber optic sensor detects that the label to be peeled has been transported to the peeling position through the detection port, the lifting cylinder first rises and then presses down, causing the pressure roller to press and bend the backing paper of the label to be peeled downwards. Under the continuous pushing of the feeding component, the label sticker on the label to be peeled separates from the backing paper and moves horizontally to the placement position of the anti-sticking block.
[0038] This solution uses a fiber optic sensor at the placement position. When the label to be peeled reaches the placement position, the lifting cylinder is activated to rise and then press down. Since the front end of the label to be peeled is the backing paper, the bending cylinder drives the pressure roller forward to press the backing paper onto the second active roller, while the label sticker is on the second platform. Subsequently, the second motor drives the second active roller, causing the backing paper to move downwards, while the label sticker will move forward under inertia to the placement position, waiting for the labeling module to work. The backing paper is bent using the second active roller and the pressure roller. The bending action is simple and efficient, and the operation is fully automated.
[0039] In a further embodiment, the lifting frame includes a support base, a lifting guide rail, a lifting slider, and a connector. The bottom of the support base is fixed to the cabinet, and the lifting guide rail is vertically installed on the rear side. The lifting slider is slidably installed on the lifting guide rail. The front end of the connector is fixed to the lifting slider, and the top of the rear end is connected to the back of the fixed base.
[0040] When the lifting cylinder rises or falls, it drives the fixed seat to rise or fall, which in turn drives the connecting piece on the lifting slider to move up / down along the lifting guide rail.
[0041] This solution utilizes a combination of lifting sliders and lifting guide rails to set up an adjustable lifting frame, which is used to coordinate with the up and down movement of the cylinder, while providing stable and reliable support.
[0042] In a further embodiment, the labeling module includes a stand, an X-axis mechanism, a Z-axis mechanism, a CCD module, and a suction module; the bottom of the stand is installed on the top surface of the cabinet, and the X-axis mechanism is installed horizontally on the upper inner side; the Z-axis mechanism is installed vertically on the moving block of the X-axis mechanism, the suction module is installed at the bottom end of the moving block, and the CCD module with the lens facing downward is installed in the middle.
[0043] This solution uses X-axis and Z-axis mechanisms to achieve two degrees of freedom in two directions, adapting to the needs of label and sticker gripping; at the same time, a CCD module is configured for mechanical vision positioning to achieve precise positioning and pasting.
[0044] In a further embodiment, the suction module includes a suction block and an air pump. The suction block has several through holes in the middle, and the through holes are connected to the air pump through air pipes.
[0045] The air pump is activated, and the airflow in the through hole is drawn through the air pipe to form a negative pressure; the adhesive block covers the label sticker, and the label sticker is sucked in by the negative pressure in the through hole, thus completing the label suction.
[0046] This solution uses a flexible suction block to draw the label sticker under negative pressure, which is highly automated, will not damage the label sticker, and can keep the label sticker in the same position, thereby reducing the difficulty of pasting and improving the pasting accuracy and efficiency.
[0047] In a further embodiment, the transport module includes a Y-axis mechanism, a tooling plate, and a product fixture. The Y-axis mechanism is radially mounted on the top surface of the cabinet, and a transport guide rail is mounted on its top surface. The tooling plate is slidably mounted on the transport guide rail, and the product fixture is mounted on its top. The product fixture is used to place the product to be labeled.
[0048] This solution places the Y-axis mechanism on the transportation of the products to be labeled. On the one hand, the precise positioning of the products can reduce the labeling difficulty of the labeling module, and on the other hand, it can simplify the assembly difficulty of the device.

[0075] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The embodiments are given for illustrative purposes only and should not be construed as limiting the present invention. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.
[0076] An automatic labeling machine is provided in this embodiment of the invention, such as... Figures 1 to 15As shown, in this embodiment, a cabinet A is provided. A labeling module B is installed at one end of the top surface of the cabinet A, and a label peeling module C and a transport module D are provided at the other end. The transport module D is installed in front of the labeling module B. The label peeling module C includes a feeding component 1, a label peeling component 2 and a receiving component 3. The label peeling component 2 is installed on one side of the end of the feeding component 1, and the receiving component 3 is provided below the end.
[0077] See Figure 2 In this embodiment, the label E to be peeled off is a continuously printed label, including a black area at the bottom as the backing paper E1, a striped gray area in the middle of the backing paper E1 as the cross-section sticker E2, and multiple rounded rectangles arranged in the middle as label stickers E3. See also Figure 2 , Figure 6 The width of the cross-section sticker E2 is slightly smaller than the width of the base paper E1, and the distance between its edge and the edge of the base paper E1 is less than the distance between the fiber optic sensor 27 and the rear edge of the placement position 242. Therefore, when the base paper E1 covers the fiber optic sensor 27, the cross-section sticker E2 also enters the top surface of the placement position 242. Thus, the base paper E1 mentioned below refers to the base paper E1 that retains the cross-section sticker E2.
[0078] When the label peeling component 2 senses that the feeding component 1 has transported the label E to be peeled to the peeling position, the label peeling component 2 first rises and then presses down to press and bend the back paper E1 of the label E to be peeled downwards. Under the continuous push of the feeding component 1, the label sticker E3 on the label E to be peeled separates from the back paper E1 and moves horizontally to the top surface of the label peeling component 2. At the same time, the receiving component 3 clamps the back paper E1 and receives it downwards.
[0079] Transport module D transports the product F to be labeled to below the labeling module B;
[0080] The labeling module B picks up the label sticker E3 from the top surface of the label peeling component 2 and moves it to the labeling position on the product F to be labeled.
[0081] In this embodiment, the feeding assembly 1 includes a base plate 11 and a frame 12, a limiting seat 13, a first guide roller group 14, a second guide roller group 15, and a feeding box 16 mounted on the base plate 11.
[0082] The frame 12 includes a first platform 121, a second platform 122, and a mounting bracket that are mechanically connected. Limit seats 13 are installed on both sides of the top surface of the first platform 121, and the middle part is used to place the label E to be peeled off. The mounting bracket includes a first vertical plate 123 and a second vertical plate 124 respectively disposed on both sides, and a crossbeam 125 connecting the first vertical plate 123 and the second vertical plate 124. The bottom of the first vertical plate 123 and the second vertical plate 124 are installed on the base plate 11, and the first platform 121, the first guide roller group 14, the second platform 122 and the second guide roller group 15 are installed in sequence in the middle, and the crossbeam 125 is installed on the top.
[0083] The first platform 121 and the second platform 122 are at the same horizontal level.
[0084] The feeding box 16 is installed on the side of the frame 12 away from the labeling module B, with an upward opening, for placing the label E to be peeled off; the feeding of the label E can be done manually or automatically by a robot (such as the labeling module B).
[0085] Among them, the limiting seat 13 is a handle structure located on both sides of the first platform 121. The range of the label placement area can be limited by designing the position of the bottom of the handle on the first platform 121.
[0086] In this embodiment, the frame 12 is set to install and fix the limiting seat 13, the first guide roller group 14 and the second guide roller group 15. The limiting seat 13 is set to limit the label placement area on the first platform 121, thereby achieving precise positioning of the label E to be peeled off. The first guide roller group 14 is inserted between the first platform 121 and the second platform 122, and the first guide roller group 14 is used to apply the moving power to the label E to be peeled off. The second guide roller group 15 is set at the end of the second platform 122 to clamp the backing paper E1 of the label E to be peeled off in conjunction with the peeling action, thereby realizing the automated separation of the backing paper E1 and the label sticker E3.
[0087] In this embodiment, the first guide roller group 14 includes a first driving roller 141, a first driven roller 142, and a first motor 143;
[0088] The first active roller 141 is installed between the first platform 121 and the second platform 122 and is horizontal at the same height as the first platform 121. One end of the roller is rotatably installed on the first vertical plate 123, and the other end is rotatably installed on the second vertical plate 124. It is also rotatably connected to the first motor 143 via a belt.
[0089] The first driven roller 142 is installed above the first driving roller 141 and at a height higher than the horizontal height of the first platform 121, and its two ends are respectively rotatably installed on the first vertical plate 123 and the second vertical plate 124;
[0090] The first motor 143 is installed in the inner cavity of the mounting bracket, and its rotating end passes through the second vertical plate 124 and is rotatably connected to the first drive roller 141 via a belt.
[0091] The label E to be peeled is placed on the first platform 121 and inserted between the first active roller 141 and the first driven roller 142. The first active roller 141 rotates under the drive of the first motor 143, and drives the first driven roller 142 to rotate, thereby moving the label E to be peeled toward the second platform 122.
[0092] In this embodiment, a symmetrical first active roller 141 and a first driven roller 142 are set between the first platform 121 and the second platform 122. The first active roller 142 is driven by the first motor 143 to move the label E to be peeled toward the second platform 122. At the same time, the first driven roller 142 below rotates synchronously under friction, so that a whole row of labels E to be peeled can move stably and be subjected to uniform force. Moreover, since the movement control is based on friction, the breakage problem caused by tension can be effectively avoided.
[0093] In this embodiment, the second guide roller group 15 includes a second driving roller 151, a second driven roller 152, and a second motor 153;
[0094] The second active roller 151 is installed at the end of the second platform 122 and is horizontal at the same height as the second platform 122. One end of the roller is rotatably installed on the first vertical plate 123, and the other end is rotatably installed on the second vertical plate 124. It is also rotatably connected to the second motor 153 via a belt.
[0095] The second driven roller 152 is installed above the second platform 122, and its two ends are respectively rotatably installed on the first vertical plate 123 and the second vertical plate 124;
[0096] The second motor 153 is installed in the inner cavity of the mounting bracket, and its rotating end passes through the second vertical plate 124 and is rotatably connected to the second drive roller 151 via a belt.
[0097] After the label E to be peeled enters the second platform 122, it is inserted between the second driven roller 152 and the second platform 122. The second active roller 151 rotates under the drive of the second motor 153. At this time, the label peeling component 2 senses that the label E to be peeled has been transported to the peeling position. The label peeling component 2 first rises and then presses down to press and bend the backing paper E1 of the label E to be peeled downward. The label sticker E3 on the label E to be peeled separates from the backing paper E1 and moves horizontally to the top surface of the label peeling component 2. At the same time, the backing paper E1 is displaced into the receiving component 3 under the drive of the second active roller 151.
[0098] In this embodiment, a second driven roller 152 is rotatably connected to the top surface of the second platform 122 to continuously press the label E to be peeled off to move towards the labeling module B, so as to prevent the front end of the label E to be peeled off from lifting up; a second active roller 151 is set below the end of the second platform 122 to provide the power for the separated bottom paper E1 to move downward, and cooperate with the receiving component 3 to directionally recycle the bottom paper E1 downward, so as to realize the automation of waste recycling.
[0099] In this embodiment, the receiving assembly 3 includes an inner guide plate 31, an outer guide plate 32, a first tensioning roller 33, a second tensioning roller 34, a tensioning seat 35, and a tensioning cylinder 36; the rear end of the tensioning seat 35 is installed at the end of the telescopic rod of the tensioning cylinder 36, and the front end is rotatably mounted with the first tensioning roller 33; the second tensioning roller 34 is rotatably mounted on the frame 12, with its outer side close to the first tensioning roller 33 and directly below the second drive roller 151;
[0100] The inner guide plate 31 is vertically mounted on the frame 12, with its top close to the second platform 122 and its bottom facing the gap between the first tension roller 33 and the second tension roller 34;
[0101] The outer guide plate 32 is vertically installed on the end face of the frame 12, with its top close to the outside of the second drive roller 151 and its bottom facing the gap between the first tension roller 33 and the second tension roller 34.
[0102] The bottom paper E1 moves downward under the drive of the second drive roller 151, and enters the gap between the first tension roller 33 and the second tension roller 34 through the inner guide plate 31 and the outer guide plate 32. At this time, the tension cylinder 36 works to drive the first tension roller 33 on the tension seat 35 to approach the second tension roller 34, so that the first tension roller 33 and the second tension roller 34 clamp the bottom paper E1. The second drive roller 151 applies a downward force to the bottom paper E1, driving the first tension roller 33 and the second tension roller 34 to rotate, completing the directional collection of the bottom paper E1.
[0103] Based on the size characteristics of continuously printed paper labels, this embodiment sets up an inner guide plate 31 and an outer guide plate 32 that cooperate with each other to guide the bottom paper E1, so that the bottom paper E1 accurately enters the gap between the first tension roller 33 and the second tension roller 34. At this time, the cylinder drives the first tension roller 33 to approach the second tension roller 34 to clamp the bottom paper E1, which can effectively prevent the bottom paper E1 from being freely transmitted and complete the automatic material collection action.
[0104] In this embodiment, the label peeling assembly 2 includes a lifting frame 21, a lifting cylinder 22, a fixed base 23, an anti-sticking block 24, a pressure roller 25, a bending cylinder 26, and a fiber optic sensor 27. The lifting cylinder 22 is installed in the middle of the back of the fixed base 23, and the anti-sticking block 24 is installed on the top. The lifting frame 21 is installed on both sides of the lifting cylinder 22, and the bottom of the lifting cylinder 22 and the lifting frame 21 are fixed on the cabinet A.
[0105] The anti-stick block 24 has two ends recessed downward to form an installation position 241, and the middle extends backward to form a placement position 242. The placement position 242 is provided with several through-plate detection ports; the fiber optic sensor 27 is installed below the detection ports.
[0106] The anti-sticking block 24 has an anti-sticking coating applied to the placement position 242 in the middle.
[0107] Two sets of bending cylinders 26 are installed in the mounting position 241, with their telescopic rods facing backward and fixed blocks installed on them;
[0108] The two ends of the pressure roller 25 are rotatably mounted on the fixed block via bearings 243, and its top is close to the placement position 242;
[0109] When the fiber optic sensor 27 detects that the label E to be peeled has been transported to the peeling position through the detection port, the lifting cylinder 22 first rises and then presses down, so that the pressure roller 25 presses down and bends the backing paper E1 of the label E to be peeled. Under the continuous push of the feeding component 1, the label sticker E3 on the label E to be peeled is separated from the backing paper E1 and moves horizontally to the placement position 242 of the anti-sticking block 24.
[0110] In this embodiment, a fiber optic sensor 27 is installed under the placement position 242. When the label E to be peeled reaches the placement position 242, the lifting cylinder 22 is activated to rise and then press down. Since the front end of the label E to be peeled is the backing paper E1, at this time the bending cylinder 26 drives the pressure roller 25 to push forward and press the backing paper E1 onto the second active roller 151, while the label sticker E3 is on the second platform 122. Subsequently, the second motor 153 drives the second active roller 151, causing the backing paper E1 to move downward, while the label sticker E3 will move forward to the placement position 242 under inertia, waiting for the labeling module B to work. The second active roller 151 and the pressure roller 25 are used to bend the backing paper E1. The bending action is simple and efficient, and the action is fully automated.
[0111] In this embodiment, the lifting frame 21 includes a support base 211, a lifting guide rail 212, a lifting slider 213, and a connector 214. The bottom of the support base 211 is fixed to the cabinet A, and the lifting guide rail 212 is vertically installed on the rear side. The lifting slider 213 is slidably installed on the lifting guide rail 212. The front end of the connector 214 is fixed to the lifting slider 213, and the top of the rear end is connected to the back of the fixed base 23.
[0112] When the lifting cylinder 22 rises or falls, it drives the fixed seat 23 to rise or fall, which in turn drives the connecting piece 214 on the lifting slider 213 to move up / down along the lifting guide rail 212.
[0113] This embodiment utilizes the combination of lifting slider 213 and lifting guide rail 212 to set up an adjustable lifting frame 21, which is used to cooperate with the up and down movement of the cylinder, while providing a stable and reliable support.
[0114] In this embodiment, the labeling module B includes a stand 4, an X-axis mechanism 5, a Z-axis mechanism 6, a CCD module 7, and a suction module 8. The bottom of the stand 4 is installed on the top surface of the cabinet A, and the X-axis mechanism 5 is installed horizontally on the inner side of the upper part. The Z-axis mechanism 6 is installed vertically on the moving block of the X-axis mechanism 5, and the suction module 8 is installed at the bottom end of the moving block, and the CCD module 7 with the lens facing downward is installed in the middle.
[0115] This embodiment uses X-axis mechanism 5 and Z-axis mechanism 6 to achieve two degrees of freedom in two directions, adapting to the gripping requirements of label sticker E3; at the same time, a CCD module 7 is configured for mechanical vision positioning to achieve precise positioning and pasting.
[0116] In this embodiment, the X-axis mechanism 5 and the Z-axis mechanism 6 can be selected according to requirements. For example, existing mature technical structures such as lead screw 92 can be selected. This embodiment does not limit them, so they will not be described in detail.
[0117] In this embodiment, the suction module 8 includes a suction block 81 and an air pump. The suction block 81 has several through holes 82 in the middle, and the through holes 82 are connected to the air pump through air pipes.
[0118] The air pump starts and draws air from the through hole 82 through the air tube to form a negative pressure; the adhesive block 81 covers the label sticker E3, and the label sticker E3 is sucked in by the negative pressure in the through hole 82, thus completing the label suction.
[0119] See Figure 12 , Figure 13 These are two different sizes of adhesive suction blocks. In practical applications, different sizes of adhesive suction blocks can be selected to ensure production line compatibility according to actual needs.
[0120] Upon receiving the signal that the label peeling component 2 has completed the label peeling action, the X-axis mechanism 5 moves above the first label, the CCD module 7 positions and identifies the label, and the X-axis mechanism 5 drives the moving block to move the adhesive suction block 81 above the label sticker E3. The Z-axis mechanism 6 descends to the height of the label sticker E3, the air pump starts to activate negative pressure, and the adhesive suction block 81 picks up the label sticker E3. After the Z-axis mechanism 6 rises to a safe height, the X-axis mechanism 5 moves to the product location, the CCD module 7 positions and identifies the product F to be labeled, the X-axis mechanism 5 moves the adhesive suction block 81 above the labeling position, the Z-axis mechanism 6 descends to apply the label sticker E3, and after the air pump shuts off the negative pressure, the Z-axis mechanism 6 rises to a safe height, completing the labeling action. After the labeling action is completed, the CCD module 7 detects whether the label application is qualified, and prompts the manual operation interface to sort out NG products.
[0121] In this embodiment, a flexible adhesive suction block 81 is used to suction the label sticker E3 under negative pressure. This method is highly automated, will not damage the label sticker E3, and can ensure that the position of the label sticker E3 remains unchanged, thereby reducing the difficulty of pasting and improving the pasting accuracy and efficiency.
[0122] In this embodiment, the transport module D includes a Y-axis mechanism 9, a tooling plate D1, and a product fixture D2. The Y-axis mechanism 9 is radially mounted on the top surface of the cabinet A, and a transport guide rail is mounted on its top surface. The tooling plate D1 is slidably mounted on the transport guide rail, and the product fixture D2 is mounted on its top. The product fixture D2 is used to place the product F to be labeled.
[0123] The Y-axis mechanism 9 includes a third motor 91, a lead screw 92, and a Y-axis slider 93. The Y-axis slider 93 has a concave structure and is slidably mounted on the lead screw 92 in the middle. The lead screw 92 is electrically connected to the third motor 91 and extends upward on both sides to connect with the bottom of the tooling plate D1.
[0124] In other embodiments, the transport module D also includes product sensors, including but not limited to pressure sensors or fiber optic sensors installed at the bottom of the product fixture D2. After a product is manually placed onto the fixture, and the sensor detects that the product F to be labeled is in place, the Y-axis mechanism 9 transports the product F to the labeling position. Upon receiving a labeling completion signal, the product is transported back to the manual loading position. After manual or mechanical inspection to determine if the product is qualified, the manual unloading and sorting process is completed.
[0125] In this embodiment, the product fixture D2 mounted on the tooling plate D1 can be replaced according to the different sizes of the products, and the production line replacement has been completed.
[0126] In this embodiment, the Y-axis mechanism 9 is arranged on the transport of the product F to be labeled. On the one hand, the labeling difficulty of the labeling module B can be reduced by accurately positioning the product F to be labeled, and on the other hand, the assembly difficulty of the device can be simplified.
[0127] In this embodiment, cabinet A includes a base plate A1 and a cabinet body A2 that are covered by upper and lower covers. The cabinet body A2 has an installation cavity for installing a host computer or controller host. The electrical components in the labeling module B, the label peeling module C, and the transport module D are electrically connected to the host computer or controller host via wiring harnesses. The cabinet body A2 also has a drawer-type waste collection box. An opening is made on the base plate A1 facing the receiving component 3 and the drawer-type waste collection box. The drawer-type waste collection box has a built-in push-pull box body A3. Universal wheels A4 are also installed at the four corners of the bottom of the cabinet body A2.
[0128] This invention addresses the characteristics of discontinuous connections in existing continuously printed paper labels by setting up a targeted feeding component 1, a peeling component 2, and a receiving component 3. The feeding component 1 provides horizontal feeding, while the peeling component 2 first rises and then presses down to compress and bend the backing paper E1 of the label E to be peeled off. Under the continuous pushing of the feeding component 1, the label sticker E3 on the label E to be peeled off separates from the backing paper E1 (separating the broken sticker E2 onto the backing paper E1, which directly enters the waste collection, thus avoiding jamming) and moves horizontally to the top surface of the peeling component 2. At the same time, the receiving component 3 clamps the backing paper E1 and vertically collects it downwards. This satisfies the separation and pickup of the label sticker E3 on continuously printed paper labels and avoids breakage and jamming caused by tensioning. A transport module D is configured to realize the automatic positioning and transport of the product F to be labeled, in conjunction with the label picking and pasting of the labeling module B, improving label pasting efficiency and labeling accuracy.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
