Description

TECHNICAL FIELD

[0001] The present application belongs to the field of outer packaging product processing, and particularly relates to a hole-containing sheet positioning device, a feeding device, a carrying and pressing device, a sheet pasting equipment and a method. BACKGROUND

[0002] In the packaging industry, the alignment and bonding of sheet holes and hole positions on outer packaging products (such as packaging boxes or shells) are common process requirements. The accurate alignment of the sheet and the product hole position directly affects the aesthetics and functionality of the packaging box. At present, the industry generally adopts a manual alignment method, in which the operator manually adjusts the position of the sheet and the outer packaging product, and realizes hole position alignment through visual observation or simple tool assistance, or uses a semi-automatic device to realize the positioning and bonding of the sheet and the outer packaging product.

[0003] Among them, the manual positioning method is not only low in efficiency, but also greatly affected by human factors in alignment accuracy, making it difficult to ensure consistency. Although the semi-automatic device can realize the positioning of the outer packaging product, it still cannot completely eliminate the dependence on manual operation for the positioning of the sheet, and lacks an integrated positioning device, making it difficult to accurately control the relative position between the sheet and the outer packaging product. In addition, due to the light and thin characteristics of the sheet, it is easy to shift or deform during positioning, further increasing the difficulty of alignment. There is no special device in the prior art that can simultaneously realize automatic positioning of the sheet and the outer packaging product and stably clamp or adsorb the sheet, resulting in low production efficiency and difficulty in improving processing quality. SUMMARY

[0004] Therefore, the present application aims to provide a hole-containing sheet positioning device, a feeding device, a carrying and pressing device, a sheet pasting equipment and a method to solve the above technical problems.

[0005] To achieve the above-mentioned purposes, the technical scheme of the present application is as follows: On the one hand, the present application provides a hole-containing sheet positioning device, comprising: a positioning mechanism comprising a driving component and a positioning component movably arranged on the driving component, the positioning component being adapted to move towards the sheet under the driving of the driving component; a sheet base fixed on the driving component, the sheet base being located between the two groups of positioning components; a sheet hole positioning pin arranged on the sheet base; a pressing piece movably arranged above the sheet hole positioning pin; and When the hole-containing sheet positioning device is used to position the sheet, the sheet hole positioning pin is used to penetrate the sheet hole to form positioning thereof, the pressing piece is located above the sheet to limit the sheet, and the positioning components respectively clamp the sheet from both sides to realize the alignment of the sheet. When taking and placing the material, the positioning component is away from the sheet, and the pressing piece is moved away from above the sheet.

[0006] In the embodiment of the present application, the sheet hole is accurately positioned by the sheet hole positioning pin, and the positioning component clamps the sheet from both sides to align it, effectively solving the problem that the sheet hole is difficult to align with the hole position on the outer packaging product due to the irregularity of the incoming sheet material. Moreover, the pressing piece is located above the sheet during positioning, limiting the sheet, preventing the sheet from deforming or flying during positioning, and ensuring the reliability of the positioning process.

[0031] In the wine box packaging design, in order to enhance the visual display effect, the light grating sheet is often pasted on the inner wall of both sides of the opening part of the wine box. The light grating sheet can not only use the refraction effect of the light grating to make the product in the box produce a three-dimensional or dynamic visual impression when the box is opened, but also has a anti-fake function. Since the light grating sheet is firmly bonded with the box body, the box body structure will be damaged when the box is opened, forming irreversible marks, thereby effectively preventing the packaging from being reused or counterfeited. At present, the pasting operation of the light grating sheet mainly relies on manual work: the operator needs to cut the light grating sheet first, and then roughly align the position by visual inspection, and manually press and paste it on the specified area inside the wine box. Since the light grating sheet itself is light and soft, it is easy to shift, wrinkle or deform due to uneven stress during picking, positioning and fitting, which further increases the difficulty of accurate alignment, often causing deviation, inclination or air bubbles in the pasting position, affecting the appearance of the finished product. More importantly, if the bonding between the light grating sheet and the packaging box is not firm enough, the light grating sheet is easy to separate from the box body when the box is opened, which cannot damage the box body structure and cannot form effective irreversible marks, which will cause the anti-fake function to fail. This manual work method is low in efficiency and high in labor intensity. Although some existing technologies try to use simple jigs for auxiliary positioning, the picking, alignment and fitting actions of the sheet (i.e. the light grating sheet) still need to be completed manually, and the overall improvement effect is limited. It is difficult to fundamentally solve the process problems caused by the material characteristics, and the production efficiency and the fitting precision cannot meet the needs of modern packaging production.

[0032] Of course, other installations requiring hole alignment are also applicable to the present patent solution, i.e. one sheet hole needs to be aligned with another sheet hole, or even two sheets need to be aligned and pasted.

[0033] The present application realizes accurate positioning and automatic bonding of the hole sheet and the box body (which can also be other materials requiring hole alignment, not limited to the material range by the term box body, but the three-dimensional box body further increases the difficulty of positioning and pasting of the hole sheet) through automatic equipment, effectively solving the problems of hole position deviation and misalignment caused by unstable operation in traditional manual methods. Through the cooperation of the hole sheet feeding device, the carrying and pressing device and the positioning device, the equipment can automatically complete a series of actions such as sheet feeding, accurate alignment and pressing and bonding, realize continuous operation in a flow line, and greatly improve the production efficiency. The equipment can stably maintain the alignment accuracy of the sheet hole and the box hole during operation, significantly improve the product quality, and reduce the quality fluctuations caused by manual intervention, so that the product qualification rate is significantly improved. The whole set of equipment has high automation degree, and the production speed is much higher than manual work, saving labor cost.

[0034] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0035] The present application provides a hole sheet positioning device 300, as shown in the accompanying Figures 2-8As shown, it comprises a positioning mechanism, a sheet base 380, sheet hole positioning pins 370 and a pressing piece 310, wherein the positioning mechanism comprises a driving component 350 and a set of positioning components 330 movably arranged on the driving component 350, the positioning components 330 are adapted to move towards the sheet 200 under the driving of the driving component 350. The sheet base 380 is fixed on the driving component 350, and the sheet base 380 is located between the two sets of positioning components 330. The sheet hole positioning pins 370 are arranged on the sheet base 380. The pressing piece 310 is movably arranged above the sheet hole positioning pins 370. When the sheet 200 is positioned using the sheet hole positioning device 300, the sheet hole positioning pins 370 penetrate the sheet hole to ensure that the sheet hole and the box hole are located on the same straight line. The pressing piece 310 is located above the sheet 200 for limiting the sheet 200, the positioning components 330 respectively clamp the sheet 200 from both sides to realize the alignment of the sheet 200, and the pressing piece 310 can prevent the sheet 200 from being bounced away under the clamping force of the positioning components 330. It should be noted that a certain gap is left between the pressing piece 310 and the sheet 200 in the limiting state, so as to avoid affecting the alignment of the sheet 200. When taking and placing the material, the positioning components 330 are away from the sheet 200, and the pressing piece 310 is moved away from above the sheet 200, so that the sheet hole sheet carrying and pressing device 500 can smoothly take away the sheet 200.

[0036] In the embodiment of the present application, the sheet hole positioning pins 370 are arranged to realize accurate positioning of the sheet hole, and the positioning components 330 clamp and automatically align the sheet 200 from both sides, effectively solving the problem of difficult alignment of the sheet hole and the box hole due to irregular incoming sheet 200. Moreover, the pressing piece 310 is located above the sheet 200 during positioning to limit it, effectively preventing the sheet 200 from deforming, shifting or bouncing during positioning. The sheet 200 can be automatically aligned by the sheet hole positioning device 300, which improves the precision of sheet 200 sticking, improves production efficiency, reduces dependence on manpower, saves labor cost, and improves production efficiency.

[0037] In an embodiment, the positioning component 330 comprises a moving piece 331, a support rod 332, a positioning plate 334, and a first elastic element 333. The moving piece 331 is movably installed on the driving component 350, and is adapted to move towards or away from the sheet hole positioning pin 370 under the driving of the driving component 350. Preferably, the moving piece 331 is an L-shaped slider, and the driving component 350 is a pneumatic cylinder. A clamping jaw on the pneumatic cylinder is fixedly connected with the moving piece 331, and is used to drive the moving piece 331. The support rod 332 is slidably arranged on the moving piece 331, and extends towards the sheet hole positioning pin 370. The positioning plate 334 is installed at the end of the support rod 332, and is adapted to abut against the side edge of the sheet 200. The first elastic element 333 is arranged between the moving piece 331 and the positioning plate 334. The positioning plate 334 forms a flexible positioning on the sheet 200 by means of the elastic force of the first elastic element 333. The first elastic element 333 can realize self-adaptive adjustment of the clamping degree and position, corrects the sheet 200 by means of the elastic force, allows a slight position adjustment under the premise of ensuring the positioning accuracy, and can avoid deformation or positioning deviation of the sheet 200 under the action of a rigid force. Preferably, the first elastic element 333 is a spring, which is sleeved on the support rod 332, and the two ends thereof are respectively abutted against the moving piece 331 and the positioning plate 334. The moving piece 331 moves to push the first elastic element 333, so that the positioning plate 334 moves towards the sheet 200 and abuts against the sheet 200. Then, the moving piece 331 continues to move, and the first elastic element 333 is compressed, so as to apply a flexible force to the sheet 200, and then the sheet 200 is positioned.

[0038] The pressing piece 310 is installed on the base 350 by means of the rotary pressing mechanism 320, and can be rotated to above the sheet 200 or away from the sheet 200 after rotation. Preferably, the rotary pressing mechanism 320 adopts a rotary pressing pneumatic cylinder, and the rotary output shaft of the rotary pressing pneumatic cylinder is connected with the tail end of the pressing piece 310, and is used to drive the pressing piece 310 to rotate. The positioning groove 311 for avoiding the sheet hole positioning pin 370 is arranged on the pressing piece 310.

[0039] Further, the tail end of the support rod 332 is fixedly connected with a limiting block, and the limiting block can abut against the side end face of the moving piece 331, so as to prevent the support rod 332 from being pulled out of the moving piece 331.

[0040] In an embodiment, as shown in FIG. 6, the positioning component 330 comprises a moving piece 331, a support rod 332, a positioning plate 334, and a first elastic element 333. The moving piece 331 is movably installed on the driving component 350, and is adapted to move towards or away from the sheet hole positioning pin 370 under the driving of the driving component 350. Preferably, the moving piece 331 is an L-shaped slider, and the driving component 350 is a pneumatic cylinder. A clamping jaw on the pneumatic cylinder is fixedly connected with the moving piece 331, and is used to drive the moving piece 331. The support rod 332 is slidably arranged on the moving piece 331, and extends towards the sheet hole positioning pin 370. The positioning plate 334 is installed at the end of the support rod 332, and is adapted to abut against the side edge of the sheet 200. The first elastic element 333 is arranged between the moving piece 331 and the positioning plate 334. The positioning plate 334 forms a flexible positioning on the sheet 200 by means of the elastic force of the first elastic element 333. The first elastic element 333 can realize self-adaptive adjustment of the clamping degree and position, corrects the sheet 200 by means of the elastic force, allows a slight position adjustment under the premise of ensuring the positioning accuracy, and can avoid deformation or positioning deviation of the sheet 200 under the action of a rigid force. Preferably, the first elastic element 333 is a spring, which is sleeved on the support rod 332, and the two ends thereof are respectively abutted against the moving piece 331 and the positioning plate 334. The moving piece 331 moves to push the first elastic element 333, so that the positioning plate 334 moves towards the sheet 200 and abuts against the sheet 200. Then, the moving piece 331 continues to move, and the first elastic element 333 is compressed, so as to apply a flexible force to the sheet 200, and then the sheet 200 is positioned. Figure 3As shown, the two moving pieces 331 are each provided with an electric eye 340. The displacement of the moving piece 331 when the material is short is different from that when the material is normally fed, and thus the displacement of the moving piece 331 can be detected by the electric eye 340 to determine whether the material is short. The moving piece 331 is driven by the cylinder to move towards the sheet base 380. When the sheet base 380 has the sheet 200, the positioning plate 334 abuts against the edge of the sheet 200, and the spring on the support rod 332 is compressed until the force is the same as the output pressure of the cylinder, and the cylinder stops pushing the moving piece 331 to advance. At this time, the position detected by the electric eye 340 is the position reached by the moving piece 331 when the sheet 200 is present. When the sheet base 380 has no sheet 200, the positioning plate 334 directly abuts against the two sides of the sheet base 380, and the spring is compressed until the moving piece 331 stops advancing. At this time, the position detected by the electric eye 340 is the position reached by the moving piece 331 when the material is short.

[0041] The bottom of the positioning mechanism is further provided with an X-direction driving mechanism 360 for driving the positioning mechanism to slide along the X-direction.

After the hopper 410 on the discharge side is emptied, the mounting frame 420 rotates 180° so that the filled hopper 410 rotates to the discharge side.

[0044] In some alternative embodiments, the number of hoppers 410 may also be set to three or more. Taking three as an example, the hoppers 410 are set at 120° intervals. When the hopper 410 on the discharge side is emptied, it is rotated 120° to the filling side for filling. Based on the technical concept of the foregoing embodiments, any flexible adjustments made by those skilled in the art to the number of hoppers 410 are covered within the scope of protection of this application.
