Description

Technical Field

[0001] The present invention belongs to the technical field of labeling, and particularly relates to a label uniform supply device for an automatic labeling machine. Background Art

[0002] In industries such as food, medicine, and daily chemicals, automatic labeling machines are widely used. The label supply device is the core of them. There are many problems with traditional devices. It is difficult to supply labels at a uniform speed, which easily leads to label stacking, wrinkling or idling. Moreover, they have poor adaptability to labels of different specifications, and there are large labeling deviations during high-speed operation. In view of the increasing market requirements for packaging quality and efficiency, it is very necessary to develop a device that can supply labels at a uniform speed, adapt to multiple specifications and has high precision.

[0003] Currently, a Chinese invention with the publication number: CN102574600B discloses a labeling machine for dispensing labels that can be derived from a web traveling along a feed path and pasting the labels onto articles traveling along an article path. The labeling machine includes: a web supply reel; a device for unwinding the web on the supply reel and feeding the web towards the pasting platform of the labeling machine, where the labels are successively pasted onto the articles that successively arrive here; a drive device for controlling the advancement of the web from which the labels are derived along the feed path FP according to the advancement of the articles to which the labels are to be pasted along the article path AP; and a web tension control device that can be selectively activated to apply a torque opposite to the unwinding direction of the web on the supply reel.

[0004] The existing label uniform supply device of an automatic labeling machine has the following disadvantages when supplying the labels required for labeling:

[0005] 1. Due to the lack of a real-time adjustment structure according to the speed of conveying labels, the speed of conveying labels cannot be adjusted in real time, reducing the flexibility of adjusting the speed during the uniform conveying of labels.

[0006] 2. Due to the lack of a real-time adjustment structure according to the spacing between conveyed labels, the spacing of conveying labels cannot be adjusted in real time, reducing the flexibility of adjusting the spacing during the uniform conveying of labels. Summary of the Invention

[0007] The purpose of the present invention is directed to an existing label uniform supply device of an automatic labeling machine, and its advantages are:

[0008] 1. Since it has a real-time adjustment structure according to the speed of conveying labels, the speed of conveying labels can be adjusted in real time, improving the flexibility of adjusting the speed during the uniform conveying of labels.

[0009] 2. Since it has a real-time adjustment structure according to the spacing between conveying labels, the spacing of label conveying can be adjusted in real time, which improves the flexibility of adjusting the spacing during the uniform conveying of labels.

[0010] The above technical object of the present invention is achieved through the following technical solutions: A label uniform supply device for an automatic labeling machine, including a body mechanism and a feeding mechanism. The body mechanism is fixedly connected to the left side of the rear of the feeding mechanism. The body mechanism includes an automatic labeling machine body and a storage component. The storage component is fixedly connected to the right side of the rear of the automatic labeling machine body. The body mechanism includes a height adjustment component, a correction component, a transmission component, an adjustment component, a displacement component, and a guiding component. The height adjustment component is fixedly connected to the left side of the rear of the automatic labeling machine body. The correction component is fixedly connected to the top of the height adjustment component. The transmission component is fixedly connected to the front side of the correction component. The adjustment component is fixedly connected to the front side of the transmission component. The displacement component is rotatably connected to the surface of the adjustment component. The guiding component is fixedly connected to the inside of the displacement component.

[0011] By adopting the above technical solutions, by setting the body mechanism and the feeding mechanism, the body mechanism can provide the labels required for uniform supply for the feeding mechanism and perform labeling processing on the labels conveyed by the feeding mechanism. The feeding mechanism can convey the labels at a uniform speed, constant speed, and quantitative spacing, which improves the flexibility of label supply.

[0012] The present invention is further configured as: The automatic labeling machine body includes a labeling machine base, a conveying plate, and a controller. The labeling machine base is fixedly connected to the top of the automatic labeling machine body. The controller is fixedly connected to the front side of the top of the automatic labeling machine body.

[0013] By adopting the above technical solutions, by setting the automatic labeling machine body, the labeling machine base is the equipment frame base of the labeling machine itself, which can support the conveying plate and the controller. The conveying plate is a device for conveying labeled items, which can convey the objects to be labeled. The controller is a control panel, which can control the overall structure of the body mechanism and the feeding mechanism.

[0014] The present invention is further configured as: The storage component includes a correction lifting hydraulic cylinder, a correction plate, correction front and rear hydraulic rods, and a storage tray. The correction lifting hydraulic cylinder is fixedly connected to the right side of the rear of the labeling machine base. The correction plate is fixedly connected to the output end of the top of the correction lifting hydraulic cylinder. The correction front and rear hydraulic rods are fixedly connected to the front side of the correction plate. The storage tray is rotatably connected to the output end of the front side of the correction front and rear hydraulic rods.

[0015] With the above technical solution, by setting up the storage component, the correction lifting hydraulic cylinder can drive the correction plate to move up and down, so as to adjust the orientation of the hydraulic rod before and after correction to adapt to the orientation of the feeding mechanism. The correction plate can limit the hydraulic rod before and after correction. The hydraulic rod before and after correction can adjust the orientation of the stock tray to adapt to the orientation of the feeding mechanism, so as to store the surface required by the feeding mechanism and provide labels for the feeding mechanism.

[0016] The present invention is further configured as follows: The height adjustment component includes a positioning base, a positioning plate and a height adjustment hydraulic rod. The positioning base is fixedly connected to the left side of the rear side of the labeling machine base. The positioning plate is fixedly connected to the rear side of the positioning base. The height adjustment hydraulic rod is fixedly connected to the top of the positioning plate.

[0017] With the above technical solution, by setting up the height adjustment component, the positioning base can cooperate with the positioning plate and the height adjustment hydraulic rod. By supporting and limiting the height adjustment hydraulic rod through the positioning base and the positioning plate, the height adjustment hydraulic rod can drive the correction component to perform height adjustment, so that the correction component can adapt to the height after the overall adjustment of the feeding mechanism.

[0018] The present invention is further configured as follows: The correction component includes a positioning frame, a correction hydraulic rod group and a correction frame. The positioning frame is fixedly connected to the top of the height adjustment hydraulic rod. The correction hydraulic rod group is fixedly connected to the front side of the positioning frame. The correction frame is fixedly connected to the output end of the front side of the correction hydraulic rod group.

[0019] With the above technical solution, by setting up the correction component, including the positioning frame, the correction hydraulic rod group and the correction frame, the positioning frame can support and limit the correction hydraulic rod group, so that the height of the correction hydraulic rod group can be changed along with the height adjustment of the height adjustment hydraulic rod. The correction hydraulic rod group can adjust the front and rear orientation of the correction frame, so that when the correction frame supports the transmission component, its front and rear orientation can be changed.

[0020] The present invention is further configured as follows: The transmission component includes a transmission motor, a transmission hydraulic rod and a limit frame. The transmission motor is fixedly connected to the rear side of the correction frame. The output end of the front side of the transmission motor penetrates through the correction frame and is rotatably connected to the front side of the correction frame. The transmission hydraulic rod is fixedly connected to the output end of the front side of the transmission motor. The limit frame is fixedly connected to the surface of the transmission hydraulic rod.

[0021] With the above technical solution, by setting up the transmission component, the transmission motor can cooperate with the transmission hydraulic rod and the limit frame. By driving the transmission hydraulic rod to rotate through the transmission motor, the transmission hydraulic rod can drive the limit frame and the adjustment component to rotate together, providing the power required for the adjustment component to convey labels. The transmission hydraulic rod can take the limit frame as a basic point to change the orientation of the adjustment component, so as to adjust the form of the adjustment component.

[0022] The present invention is further configured that: the adjustment component includes a positioning ring, a guiding groove and a positioning top plate. The positioning ring is fixedly connected to the front side of the limiting frame. The positioning top plate is fixedly connected to the output end of the front side of the driving hydraulic rod. The guiding grooves are respectively formed on the surfaces of the positioning ring and the positioning top plate.

[0023] By adopting the above technical solution, through the arrangement of the adjustment component, the positioning ring can cooperate with the guiding groove and the positioning top plate. By positioning the positioning ring on the limiting frame, when the positioning top plate moves close to and away from the positioning ring along with the driving hydraulic rod, the displacement components in the guiding groove can respectively move along the positioning ring and the positioning top plate, so that the orientation of the displacement components on the positioning ring and the positioning top plate can be adjusted, and the shape of the positioning top plate itself and the guiding component can be changed after the orientation is adjusted.

[0024] The present invention is further configured that: the displacement component includes a displacement rod, a displacement plate and a displacement frame. The displacement rod is rotatably connected to the inner side of the guiding groove. The displacement plate is rotatably connected to the side of the displacement rod away from the positioning ring. The displacement frame is rotatably connected to the inner side of the displacement plate.

[0025] By adopting the above technical solution, through the arrangement of the displacement component, the displacement rod can cooperate with the displacement plate and the displacement frame. By the displacement rod moving along the positioning ring and the positioning top plate respectively, the angle of the displacement rod itself can be changed with the front side and the rear side of the displacement plate as the fixed points. Thus, it will drive the displacement plate to approach or move away from the positioning ring along with the movement of the positioning ring and the positioning top plate, and at the same time will drive the displacement frame to approach and move away from the positioning top plate, so as to achieve the effect of driving the displacement frame to displace. And when the displacement frame displaces, the displacement frames nearby will move away from or approach each other, so that the distance between each displacement frame and the distance between each displacement frame and the positioning ring and the positioning top plate can be changed. Finally, the distance between the guiding components and the distance between the guiding components and the adjustment component can be changed, and the speed and distance of the uniform conveying of the labels can be changed.

[0026] The present invention is further configured that: the guiding component includes a drainage outer shell, a guiding net and an air extraction electric fan. The drainage outer shell is fixedly connected to the inner side of the displacement frame. The guiding net is fixedly connected to the inner side of the drainage outer shell. The air extraction electric fan is fixedly connected to the side of the drainage outer shell away from the guiding net.

[0027] By adopting the above technical solution, through the arrangement of the guiding component, the drainage outer shell can cooperate with the guiding net and the air extraction electric fan. By the air extraction electric fan extracting the air in the drainage outer shell from the guiding net, the guiding net can have negative pressure, so that the labels can be adsorbed and driven to move on the surface along with the movement of the displacement component.

[0028] The present invention is further configured that: the guiding net is set as an arc surface, and a protective net is provided at the output end of the air extraction electric fan.

[0029] With the above technical solution, by setting up a protective net, the output end of the air extraction fan can be protected, external objects can be intercepted, and the guiding net is set as an arc surface, which can increase the contact surface with the label and better limit the label.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. By setting up the body mechanism, the automatic labeling machine body can cooperate with the storage component to store the labels through the storage component. It can change its own orientation along with the orientation adjustment of the feeding mechanism to adapt to the orientation of the feeding mechanism, so as to stably provide labels for the feeding mechanism. The automatic labeling machine body can paste the labels conveyed by the feeding mechanism on the object to be labeled, and at the same time can convey the object, improving the stability during label conveyance.

[0032] 2. By setting up the feeding mechanism, the height adjustment component can cooperate with the correction component, transmission component, adjustment component, displacement component and guiding component. By adjusting the height of the correction component through the height adjustment component, the height of the correction component can be adjusted in real time to adapt to the required orientation during label conveyance. The correction component can adjust the front and rear orientation of the transmission component in real time to adapt to the required orientation during label conveyance. The transmission component can drive the adjustment component to adjust the orientation, and at the same time can provide power for the adjustment component to convey the label, driving the adjustment component to rotate. The adjustment component can push forward and backward along with the transmission component, and can adjust the shape of the displacement component, so that the displacement component can achieve contraction and expansion, and at the same time adjust the distance between the guiding components. The guiding components can adsorb and convey the labels, so as to provide traction for the label conveyance, and finally realize the adjustment of the distance between the labels during conveyance and the speed of label conveyance. Since the conveyance of the labels is only provided by a single power source of the transmission component, the speed can always be kept uniform. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the body mechanism 1, the automatic labeling machine body 11 can cooperate with the storage component 12, store labels through the storage component 12, and can change its own orientation together with the orientation adjustment of the feeding mechanism 2 to adapt to the orientation of the feeding mechanism 2, so as to stably provide labels for the feeding mechanism 2. The automatic labeling machine body 11 can paste the labels conveyed by the feeding mechanism 2 on the object to be labeled, and can convey the object at the same time, improving the stability during label conveying.

[0046] As Figure 3As shown, the automatic labeling machine body 11 includes a labeling machine base 111, a conveying plate 112, and a controller 113. The labeling machine base 111 is fixedly connected to the top of the automatic labeling machine body 11, and the controller 113 is fixedly connected to the front side of the top of the automatic labeling machine body 11.

The front and rear correction hydraulic rod 123 is fixedly connected to the front side of the correction plate 122. The storage tray 124 is rotatably connected to the output end of the front side of the front and rear correction hydraulic rod 123. By providing the storage assembly 12, the correction lifting hydraulic cylinder 121 can drive the correction plate 122 to move up and down, so as to adjust the orientation of the front and rear correction hydraulic rod 123 to adapt to the orientation of the feeding mechanism 2. The correction plate 122 can limit the front and rear correction hydraulic rod 123. The front and rear correction hydraulic rod 123 can adjust the orientation of the storage tray 124 to adapt to the orientation of the feeding mechanism 2, so as to store the surface required by the feeding mechanism 2 and provide labels for the feeding mechanism 2.

[0048] Brief description of the usage process: First, install the labels in the storage tray 124, then control the overall structures of the body mechanism 1 and the feeding mechanism 2 through the controller 113, and then place the objects to be labeled on the conveying plate 112.

When the feeding mechanism 2 evenly conveys the labels to the labeling position of the automatic labeling machine body 11, the correction lifting hydraulic cylinder 121 can drive the correction plate 122 to adjust the height, and the front and rear correction hydraulic rod 123 drives the storage tray 124 to adjust the front and rear orientation. After adapting to the orientation of the feeding mechanism 2, the automatic labeling machine body 11 can label the objects.

[0049] Embodiment 2:

[0050] Refer to Figures 4-9, A label uniform supply device for an automatic labeling machine, including a feeding mechanism 2. The main body mechanism 1 is fixedly connected to the left side of the rear of the feeding mechanism 2. The main body mechanism 1 includes a height adjustment component 21, a correction component 22, a transmission component 23, an adjustment component 24, a displacement component 25, and a guiding component 26. The height adjustment component 21 is fixedly connected to the left side of the rear of the automatic labeling machine body 11. The correction component 22 is fixedly connected to the top of the height adjustment component 21. The transmission component 23 is fixedly connected to the front side of the correction component 22.

By setting the feeding mechanism 2, the height adjustment component 21 can cooperate with the correction component 22, the transmission component 23, the adjustment component 24, the displacement component 25, and the guiding component 26. By adjusting the height of the correction component 22 through the height adjustment component 21, the height of the correction component 22 can be adjusted in real time, so as to adapt to the required orientation during label conveying. The correction component 22 can adjust the front and rear orientation of the transmission component 23 in real time, so as to adapt to the required orientation during label conveying. The transmission component 23 can drive the adjustment component 24 to perform orientation adjustment, and at the same time can provide power for the adjustment component 24 to convey the label, driving the adjustment component 24 to rotate. The adjustment component 24 can be pushed forward and backward along with the transmission component 23, and can adjust the shape of the displacement component 25, so that the displacement component 25 can be contracted and expanded, and at the same time adjust the distance between the guiding components 26. The guiding component 26 can adsorb and convey the label, so as to provide traction for the label conveying, and finally realize the adjustment of the distance between the labels during conveying and the speed of label conveying. Since the conveying of the label is only provided by a single power source of the transmission component 23, the speed can always be kept uniform.

[0051] As Figure 5 shown, the height adjustment component 21 includes a positioning base 211, a positioning plate 212, and a height adjustment hydraulic rod 213. The positioning base 211 is fixedly connected to the left side of the rear of the labeling machine base 111. The positioning plate 212 is fixedly connected to the rear of the positioning base 211. The height adjustment hydraulic rod 213 is fixedly connected to the top of the positioning plate 212. By setting the height adjustment component 21, the positioning base 211 can cooperate with the positioning plate 212 and the height adjustment hydraulic rod 213. By supporting and limiting the height adjustment hydraulic rod 213 through the positioning base 211 and the positioning plate 212, the height adjustment hydraulic rod 213 can drive the correction component 22 to perform height adjustment, so that the correction component 22 can adapt to the height after the overall adjustment of the feeding mechanism 2.

[0052] As Figure 5As shown in the figure, the correction assembly 22 includes a positioning frame 221, a correction hydraulic rod group 222, and a correction frame 223. The positioning frame 221 is fixedly connected to the top of the height-adjusting hydraulic rod 213. The correction hydraulic rod group 222 is fixedly connected to the front side of the positioning frame 221. The correction frame 223 is fixedly connected to the output end on the front side of the correction hydraulic rod group 222. By providing the correction assembly 22, the positioning frame 221, the correction hydraulic rod group 222, and the correction frame 223, the positioning frame 221 can support and limit the correction hydraulic rod group 222, so that the height of the correction hydraulic rod group 222 can be changed along with the height adjustment of the height-adjusting hydraulic rod 213. The correction hydraulic rod group 222 can adjust the front-back orientation of the correction frame 223, so that the front-back orientation of the correction frame 223 can be changed when the correction frame 223 supports the transmission assembly 23.

[0053] As Figure 6 shown in the figure, the transmission assembly 23 includes a transmission motor 231, a transmission hydraulic rod 232, and a limit frame 233. The transmission motor 231 is fixedly connected to the rear side of the correction frame 223. The output end on the front side of the transmission motor 231 penetrates the correction frame 223 and is rotatably connected to the front side of the correction frame 223. The transmission hydraulic rod 232 is fixedly connected to the output end on the front side of the transmission motor 231. The limit frame 233 is fixedly connected to the surface of the transmission hydraulic rod 232. By providing the transmission assembly 23, the transmission motor 231 can cooperate with the transmission hydraulic rod 232 and the limit frame 233. By driving the transmission hydraulic rod 232 to rotate through the transmission motor 231, the transmission hydraulic rod 232 can drive the limit frame 233 and the adjustment assembly 24 to rotate together, providing the power required for the adjustment assembly 24 to convey labels. The transmission hydraulic rod 232 can change the orientation of the adjustment assembly 24 based on the limit frame 233, so that the shape of the adjustment assembly 24 can be adjusted.

[0054] As Figure 7 shown in the figure, the adjustment assembly 24 includes a positioning ring 241, a guiding groove 242, and a positioning top plate 243. The positioning ring 241 is fixedly connected to the front side of the limit frame 233. The positioning top plate 243 is fixedly connected to the output end on the front side of the transmission hydraulic rod 232. The guiding grooves 242 are respectively formed on the surfaces of the positioning ring 241 and the positioning top plate 243. By providing the adjustment assembly 24, the positioning ring 241 can cooperate with the guiding groove 242 and the positioning top plate 243. By positioning the positioning ring 241 on the limit frame 233, when the positioning top plate 243 moves closer to and away from the positioning ring 241 along with the transmission hydraulic rod 232, the displacement assembly 25 in the guiding groove 242 can move along the positioning ring 241 and the positioning top plate 243 respectively, so that the orientation of the displacement assembly 25 on the positioning ring 241 and the positioning top plate 243 can be adjusted, and the shapes of the positioning top plate 243 and the guiding assembly 26 can be changed after the orientation is adjusted.

[0055] AsFigure 7 As shown in the figure, the displacement component 25 includes a displacement rod 251, a displacement plate 252 and a displacement frame 253. The displacement rod 251 is rotatably connected to the inner side of the guiding groove 242. The displacement plate 252 is rotatably connected to the side of the displacement rod 251 away from the positioning ring 241. The displacement frame 253 is rotatably connected to the inner side of the displacement plate 252. By providing the displacement component 25, the displacement rod 251 can cooperate with the displacement plate 252 and the displacement frame 253. By moving the displacement rod 251 along the positioning ring 241 and the positioning top plate 243 respectively, the angle of the displacement rod 251 can be changed with the front side and the rear side of the displacement plate 252 as the fixed points. Thus, with the movement of the positioning ring 241 and the positioning top plate 243, the displacement plate 252 will be driven to approach or move away from the positioning ring 241, and at the same time, the displacement frame 253 will be driven to approach and move away from the positioning top plate 243, thereby achieving the effect of driving the displacement of the displacement frame 253. And when the displacement frame 253 is displaced, the adjacent displacement frames 253 will move away from or close to each other, so that the distance between each displacement frame 253 and the distance between each displacement frame 253 and the positioning ring 241 and the positioning top plate 243 can be changed. Finally, the distance between the guiding components 26 and the distance between the guiding components 26 and the adjusting component 24 are changed, and the speed and distance of the uniform conveying of the labels are changed.

[0056] As Figure 8 As shown in the figure, the guiding component 26 includes a drainage housing 261, a guiding net 262 and an air extraction fan 263. The drainage housing 261 is fixedly connected to the inner side of the displacement frame 253. The guiding net 262 is fixedly connected to the inner side of the drainage housing 261. The air extraction fan 263 is fixedly connected to the side of the drainage housing 261 away from the guiding net 262. By providing the guiding component 26, the drainage housing 261 can cooperate with the guiding net 262 and the air extraction fan 263. By extracting the air in the drainage housing 261 from the guiding net 262 through the air extraction fan 263, the guiding net 262 can have negative pressure, so that the label can be adsorbed and driven to move along with the movement of the displacement component 25.

[0057] As Figure 9 As shown in the figure, the guiding net 262 is set as an arc surface, and a protective net is provided at the output end of the air extraction fan 263. By providing the protective net, the output end of the air extraction fan 263 can be protected and foreign objects can be intercepted. The guiding net 262 being set as an arc surface can increase the contact surface with the label and can better limit the label.

[0058] Brief description of the usage process: First, when the body mechanism 1 conveys the label to the guiding net 262, the air extraction fan 263 will extract the air at the drainage housing 261, causing the guiding net 262 to adsorb the label on its surface due to negative pressure. Then, the driving hydraulic rod 232 drives the positioning top plate 243 to gradually approach the positioning ring 241. The displacement rod 251 will gradually change its angle in the guiding groove 242 with the approach of the positioning ring 241 and the positioning top plate 243 based on the displacement plate 252. At the same time, when changing the angle, it drives the displacement plate 252 to change its angle on the displacement frame 253, and at the same time drives the displacement frame 253 to gradually move away from the positioning ring 241 and the positioning top plate 243, driving the drainage housing 261 to gradually expand outwards. Until it expands to the required position, stop the driving hydraulic rod 232. Then, let the height-adjusting hydraulic rod 213 drive the positioning frame 221 to adjust the height of the calibration hydraulic rod group 222. Then, let the calibration hydraulic rod group 222 drive the calibration frame 223 to adjust the orientation of the driving motor 231 until it adapts to the orientation of the displacement assembly 25 after deformation. After that, the driving motor 231 will drive the driving hydraulic rod 232 to rotate the displacement assembly 25 and the guiding assembly 26, so that the guiding assembly 26 drives the label to move at a constant speed and provides the label for the body mechanism 1.
