Description

Technical Field

[0001] This invention relates to the field of film product manufacturing technology, and in particular to an automatic labeling device for double-sided laminated products. Background Technology

[0002] For some thin-film products, the cleanliness and smoothness of their surface directly determine their quality and affect their subsequent applications. Therefore, these thin-film products are often double-sided coated before leaving the factory to protect both sides of the product.

[0003] However, due to the high surface smoothness and gloss of film products, the coating itself is difficult to peel off directly after being combined with a film. This makes removing the coating from both sides a production burden and seriously affects production efficiency in the subsequent industrial applications of these films. Therefore, to improve the efficiency of removing the coating from both sides, most manufacturers affix easy-tear labels to the coating on both sides of the film product to facilitate subsequent removal.

[0004] However, currently, the application of easy-tear labels to double-sided laminated products is mostly done manually (because existing equipment can only mechanically label one side). This method is clearly time-consuming and labor-intensive, and it's difficult to centrally control the quality and placement of the labels, easily leading to defective products. Therefore, there is a need for automated, batch-process label application equipment. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the technical problem solved by the present invention is: how to improve the adhesion quality of labels on double-sided laminated products.

[0006] To achieve the above objectives, the present invention provides an automatic labeling device for double-sided laminated products, comprising: The product circulation transport component includes a loading component, a transport component, and a unloading component, with the loading and unloading components located at opposite ends of the transport component. The loading component includes a loading suction cup and a first moving component, which drives the loading suction cup to move longitudinally and vertically, and the loading suction cup is used to adsorb the top surface of the product. The transport component includes a loading station, a transport belt, and an unloading station, with the loading and unloading stations located at opposite ends of the transport belt. The lower end labeling component is located on one side of the loading station. The lower end labeling component includes a second moving component and a first label suction cup. The second moving component is used to drive the first label suction cup to move horizontally and vertically. The first label suction cup is used to adsorb the bottom surface of the easy-tear label. The upper labeling component is located on one side of the unloading station. The upper labeling component includes a third moving component and a second label suction cup. The third moving component is used to drive the second label suction cup to move horizontally and vertically. The second label suction cup is used to adsorb the top surface of the easy-tear label.

[0007] By adopting the above technical solution, the double-sided coated product is adsorbed by the suction cup of the feeding component and then placed on the feeding station of the transport component. Before placement, i.e., when the product is suspended in the air, the second moving component drives the first label suction cup with the easy-tear label to move laterally until the easy-tear label is located at the labeling position on the bottom of the product. The first label suction cup brings the easy-tear label close to the product for affixing. At the same time, the feeding suction cup acts as a support structure during the affixing process, preventing the product from shifting or bending significantly during the affixing process, thus completing the automatic labeling of the bottom of the product. After the bottom labeling is completed, the product is placed on the feeding station. The product is transported to the unloading station via a conveyor belt. The third moving component drives the second label suction cup, which holds the easy-tear label, to move laterally until the label is positioned on the top of the product for labeling. The second label suction cup then brings the label closer to the product for affixing. At this point, the conveyor belt acts as a support, completing the automatic labeling process on the top of the product. Therefore, this automatic labeling equipment can automatically label both sides of double-sided laminated products without requiring the product to be flipped, thus improving efficiency. Furthermore, during the labeling process, all structural movements are linear, simplifying positioning and preventing label misalignment, thereby improving the labeling quality on double-sided laminated products.

[0008] In one embodiment, the first moving component includes a connecting beam, a longitudinal driving component, and a vertical driving component. The connecting beam is provided with a plurality of feeding suction cups. The vertical driving component is used to drive the connecting beam to move vertically, and the longitudinal driving component is used to drive the vertical driving component to move longitudinally.

[0009] By adopting the above technical solution, it is easy to stably adsorb products, and the number and spacing of the feeding suction cups can be changed according to the adsorption requirements of different products. At the same time, the feeding suction cups can move synchronously to avoid the failure of some feeding suction cups to adsorb.

[0010] In one embodiment, the feeding suction cup includes a connecting rod and a pressing plate. The connecting rod has an adsorption channel inside, and an adsorption tube is provided in the adsorption channel. One end of the adsorption tube is located at the port of the adsorption channel, and the other end of the adsorption tube is connected to the adsorber. The pressing plate is sleeved around the connecting rod, and the bottom surface of the pressing plate is lower than the port of the connecting rod.

[0011] By adopting the above technical solution, the contact area between the suction cup and the product is increased, thus avoiding damage to the flatness of the product.

[0012] In one embodiment, the unloading assembly has the same structure as the loading assembly.

[0013] By adopting the above technical solution, the product is cut in the same way.

[0014] In one embodiment, the second moving component includes a lateral drive component and a suction cup base, the suction cup base being retractably disposed inside the lateral drive component, and a plurality of first label suction cups being disposed on the top of the suction cup base.

[0015] By adopting the above technical solution, easy-tear labels are stably adsorbed, and during labeling, the first label suction cup presses the easy-tear label onto the product, improving the label adhesion quality.

[0016] In one embodiment, the top surface of the suction cup base includes a first region and a second region. A first label suction cup is disposed in the first region and is located in a straight line. The second region is provided with a groove, and a slider is disposed inside the groove. A scraper is disposed on the slider, and the end of the scraper away from the slider is located on the same horizontal plane as the end of the first label suction cup away from the suction cup base.

[0017] By adopting the above technical solution, during label pasting, the area of ​​the easy-tear label that is not adsorbed by the first label suction cup is pressed onto the product by the scraper, thereby further improving the label pasting quality.

[0018] In one embodiment, the suction cup base is provided with pressing components on both sides. The top surface of the pressing components is at the same horizontal plane as the end of the first label suction cup away from the suction cup base. The pressing components are used to abut against the bottom corner of the product.

[0019] By adopting the above technical solutions, product warping is avoided, which would negatively impact the adhesion quality. At the same time, the pressing component presses on the product, preventing displacement of the product during the scraper's operation, further improving the label adhesion quality.

[0020] In one embodiment, the upper labeling component and the lower labeling component are located on the same side of the product circulation transport component. The upper labeling component includes a suction cup base, and pressing components are provided on both sides of the suction cup base. The pressing components are used to abut against the top corner of the product.

[0021] By adopting the above technical solution, if the product warps during the labeling process caused by the lower end labeling component, the product can be flattened by the pressing component of the upper end labeling component.

[0022] In one embodiment, the transport assembly further includes multiple support platforms, which are sequentially arranged on the transport belt along the transport direction of the transport belt, and the support platforms are used to place products.

[0023] By adopting the above technical solution, the transportation of the product is facilitated, and the support effect of the support platform is better when labeling the upper labeling component.

[0024] In one embodiment, a limiting component is provided on the support platform to limit the position of the product on the support platform.

[0025] By adopting the above technical solutions, the accuracy of product positioning is improved, and product displacement is avoided during the labeling process, thereby further improving the labeling quality.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. The double-sided laminated product is adsorbed by the suction cup of the feeding component and then placed on the feeding station of the transport component. Before placement, while the product is suspended, the second moving component moves the first label suction cup, which holds the easy-tear label, laterally until the label is located at the bottom of the product. The first label suction cup then brings the label closer to the product for affixing. Simultaneously, the feeding suction cup acts as a support structure during the affixing process, preventing displacement or significant bending of the product, thus completing the automatic labeling of the bottom of the product. After bottom labeling, the product is placed on the feeding station and... The conveyor belt transports the product to the unloading station. The third moving component drives the second label suction cup, which holds the easy-tear label, to move laterally until the label is positioned on the top of the product for labeling. The second label suction cup then brings the label closer to the product for affixing. At this point, the conveyor belt acts as a support, completing the automatic labeling process on the top of the product. Therefore, this automatic labeling equipment can automatically label both sides of double-sided laminated products without requiring the product to be flipped, thus improving efficiency. Furthermore, during the labeling process, all structural movements are linear, simplifying positioning and preventing label misalignment, thereby improving the labeling quality on double-sided laminated products. 2. Through the specific design of the scraper and the holding component, when the label is pasted, the scraper presses the area of ​​the easy-tear label without the first label suction cup onto the product, and the holding component prevents the product from warping, which would have an adverse effect on the pasting quality. At the same time, the pressing of the holding component onto the product prevents the product from shifting during the scraper's operation, further improving the label pasting quality.

Detailed Implementation

[0029] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The automatic labeling equipment for double-sided laminated products in this embodiment of the invention is described in [reference needed]. Figure 1 , Figure 4 As shown, the automatic labeling equipment for double-sided laminated products includes a product circulation transport component 2, which includes a feeding component 1, a transport component 2, and a discharging component. The feeding component 1 and the discharging component are located at opposite ends of the transport component 2. The feeding component 1 includes a feeding suction cup 8 and a first moving component. The first moving component is used to drive the feeding suction cup 8 to move longitudinally and vertically. The feeding suction cup 8 is used to adsorb the top surface of the product. The transport component 2 includes a feeding station 201, a transport belt 202, and a discharging station 203. The feeding station 201 and the discharging station 203 are located at opposite ends of the transport belt 202. The lower end labeling component 3 is located on one side of the loading station 201. The lower end labeling component 3 includes a second moving component and a first label suction cup 11. The second moving component is used to drive the first label suction cup 11 to move horizontally and vertically. The first label suction cup 11 is used to adsorb the bottom surface of the easy-tear label. The upper labeling component 4 is located on one side of the unloading station 203. The upper labeling component 4 includes a third moving component and a second label suction cup. The third moving component is used to drive the second label suction cup to move horizontally and vertically. The second label suction cup is used to adsorb the top surface of the easy-tear label.

[0031] Therefore, this invention uses the suction cup 8 of the feeding component 1 to adsorb the double-sided coated product, and then places it on the feeding station 201 of the transport component 2. Before placement, i.e., when the product is suspended, the second moving component drives the first label suction cup 11, which adsorbs the easy-tear label, to move laterally until the easy-tear label is located at the labeling position on the bottom of the product. The first label suction cup 11 brings the easy-tear label close to the product for affixing. At the same time, the feeding suction cup 8 acts as a support structure during the affixing process, preventing the product from shifting or bending significantly during the affixing process, thus completing the automatic labeling of the bottom of the product. After the bottom labeling is completed, the product is placed on the feeding station 201. 1. The product is transported to the unloading station 203 via conveyor belt 202. The third moving component drives the second label suction cup, which holds the easy-tear label, to move laterally until the easy-tear label is located at the labeling position on the top of the product. The second label suction cup then brings the easy-tear label close to the product for affixing. At this time, the conveyor belt 202 can act as a support, completing the automatic labeling of the top of the product. Therefore, this automatic labeling equipment can automatically label both sides of double-sided laminated products without the need to flip the product, improving efficiency. Furthermore, during the labeling process, the movement of the structure is all linear, making positioning simple and avoiding label misalignment, thus improving the labeling quality on double-sided laminated products.

[0032] Preferred, see Figure 1 , Figure 2 As shown, a specific structure of a first moving component is provided: The first moving component includes a connecting beam 103, a longitudinal drive component 101, and a vertical drive component 102. The connecting beam 103 is provided with a plurality of feeding suction cups 8. The vertical drive component 102 is used to drive the connecting beam 103 to move vertically, and the longitudinal drive component 101 is used to drive the vertical drive component 102 to move longitudinally.

[0033] Specifically, to improve the stability of the product when it is adsorbed by the feeding suction cup 8, multiple feeding suction cups 8 can be used to adsorb the product simultaneously according to actual needs. The number and spacing of the feeding suction cups 8 can be designed to ensure stable adsorption of the product. At the same time, the longitudinal drive component 101 can move longitudinally along the top track 5, and the vertical drive component 102 can move up and down on the longitudinal drive component 101, thereby driving the connecting beam 103 to move longitudinally and vertically. Thus, the feeding suction cups 8 can move synchronously, avoiding the failure of some feeding suction cups 8 to adsorb, i.e., the movement error caused by asynchrony.

[0034] Further, see Figure 3As shown, the feeding suction cup 8 includes a connecting rod 801 and a pressing plate 804. The connecting rod 801 has an adsorption channel 802 inside, and an adsorption tube 803 is provided in the adsorption channel 802. One end of the adsorption tube 803 is located at the port of the adsorption channel 802, and the other end of the adsorption tube 803 is connected to the adsorber. The pressing plate 804 is sleeved on the periphery of the connecting rod 801, and the bottom surface of the pressing plate 804 is lower than the port of the connecting rod 801.

[0035] Specifically, when the adsorption tube 803 generates suction, the area around the adsorption point of the product will come into contact with the pressing plate 804, thereby increasing the contact area between the adsorption surface of the feeding suction cup 8 and the product, dispersing the force at the adsorption point, and thus avoiding damage to the flatness of the product.

[0036] Preferably, the unloading component has the same structure as the loading component 1.

[0037] Specifically, both have the same structure, namely, a moving component and a connecting beam 103 with multiple suction cups. However, during operation, the feeding component 1 moves the product in the first placement area 6 to the transport component 2, and the unloading component moves the product on the transport component 2 to the second placement area 7.

[0038] Preferred, see Figure 4 As shown, a specific structure of a second moving component is provided: The second moving component includes a lateral drive component 9 and a suction cup base 10, with a plurality of first label suction cups 11 disposed on the top of the suction cup base 10.

[0039] Specifically, when the product moves to the labeling position, the lateral drive component 9 drives the suction cup base 10 to move laterally until the easy-tear labels adsorbed on the multiple first label suction cups 11 move directly above the labeling position. The suction cup base 10 then extends outward to bring the easy-tear labels closer to the product until a preset distance is moved, or an increase in pressure is detected at the end of the first label suction cup 11. In the above scheme, a displacement sensor or a pressure sensor can be added to improve the labeling accuracy.

[0040] Furthermore, the top surface of the suction cup base 10 includes a first region and a second region. The first label suction cup 11 is disposed in the first region and is located in a straight line. The second region is provided with a groove 12, and a slider is disposed inside the groove 12. A scraper 13 is disposed on the slider. The end of the scraper 13 away from the slider is on the same horizontal plane as the end of the first label suction cup 11 away from the suction cup base 10.

[0041] Specifically, when applying the label, the scraper 13 presses the area of ​​the easy-tear label without the first label suction cup 11 onto the product, further improving the label application quality.

[0042] Furthermore, the suction cup base 10 is provided with pressing components 14 on both sides. The top surface of the pressing component 14 is on the same horizontal plane as the end of the first label suction cup 11 away from the suction cup base 10. The pressing component 14 is used to abut against the bottom corner of the product.

[0043] Specifically, through the specific design of the scraper 13 and the holding component 14, when the label is pasted, the scraper 13 presses the area of ​​the easy-tear label without the first label suction cup 11 onto the product, and the holding component 14 prevents the product from warping, which would have an adverse effect on the pasting quality. At the same time, the pressing of the holding component 14 onto the product prevents the product from shifting during the operation of the scraper 13, further improving the pasting quality of the label.

[0044] Preferably, the upper labeling component 4 and the lower labeling component 3 are located on the same side of the product circulation transport component 2. The upper labeling component 4 includes a suction cup base 10, and pressing components 14 are provided on both sides of the suction cup base 10. The pressing components 14 are used to abut against the top corner of the product.

[0045] Specifically, if the product warps during the labeling process caused by the lower end labeling component 3, the product can be flattened by the pressing component 14 of the upper end labeling component 4.

[0046] Preferred, see Figure 1 , Figure 5 As shown, the transport component 2 also includes multiple support platforms 15, which are sequentially arranged on the transport belt 202 along the transport direction of the transport belt 202. The support platforms 15 are used to place products.

[0047] Furthermore, a limiting component 16 is provided on the support platform 15, which is used to limit the position of the product on the support platform 15.

[0048] Specifically, the support platform 15 is fixedly installed on the conveyor belt 202 and moves as the conveyor belt 202 rotates. The product can be placed on the support platform 15 to facilitate the transportation of the product. When the labeling component 4 is applied to the upper surface, the support effect of the support platform 15 is better. The limiting component 16 can improve the accuracy of product positioning and prevent the product from shifting during the labeling process, thereby further improving the labeling quality.

[0049] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
