Description

Technical Field

[0001] This invention relates to the field of glass production technology, and in particular to a glass paper-laying line and a paper-laying method. Background Technology

[0002] Flat glass is easily scratched during transportation and storage, or mold can grow on its surface when exposed to moisture and heat. Therefore, glass sheets on the production line are usually powdered and lined with paper before being stacked. However, powdering is not only harmful to the human body, but also less effective than lining with paper. Therefore, lining with paper is currently the most widely used glass packaging method to prevent scratches and mold growth by most glass manufacturers.

[0003] Traditional manual paper-laying requires the use of stacking machinery; one sheet of glass is placed and then one sheet of paper is laid. This method is labor-intensive, has low precision and is uneven, poorly coordinated with the production line, has low production efficiency, and poses safety hazards during operation. Currently, automated equipment is gradually replacing manual paper-laying.

[0004] However, existing equipment has the following shortcomings in the automated paper laying process: 1) It cannot cut release paper of appropriate size to fit different glass sizes, resulting in paper waste or poor isolation effect; 2) The equipment has poor integration with the production line, requiring the glass to be transferred off the production line, which is inefficient and increases the risk of glass damage; 3) The paper laying effect is difficult to guarantee, with uneven laying and wrinkling, requiring manual inspection; 4) During the paper picking process, two or more sheets of paper may be pulled out, causing the equipment to alarm due to multiple layers of paper, increasing manual maintenance and packaging costs; 5) Due to the limitation of factory space, the large size of the equipment and the complex and cumbersome operation are difficult to implement.

[0005] Therefore, further optimization of the equipment and its operation is needed. Summary of the Invention

[0006] Based on the above problems, the purpose of this invention is to provide a glass paper laying line and paper laying method, which improves the automation of the paper laying action, ensures the paper laying effect, and improves production efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A glass paper laying line, comprising:

[0009] Glass unloading roller conveyor, used to transport sheets of shaped glass;

[0010] The paper-laying conveyor line, located on one side of the glass unloading roller conveyor, is used to transport glass to the paper-laying station.

[0011] The first transfer mechanism is used to transfer glass sheets one by one from the glass unloading roller to the paper laying conveyor line;

[0012] The paper-laying mechanism is located at the paper-laying station. The paper-laying mechanism includes a release paper roll, a paper-pulling assembly, and a cutting assembly. The release paper roll is located above the glass on the paper-laying conveyor line. The paper-pulling assembly is used to clamp the paper end of the release paper roll and pull it out along the glass conveying direction so that the paper end is aligned with the end of the glass. The cutting assembly is used to cut the release paper roll according to the size of the glass to form release paper segments laid on the glass.

[0013] The stacking platform, located on one side of the paper-laying conveyor line, is used for stacking glass.

[0014] The second transfer mechanism is used to transfer the glass with release paper sections laid on it from the paper-laying station to the stacking platform.

[0015] Optionally, the paper pulling assembly includes first linear modules located on both sides of the paper laying conveyor line and arranged along the conveying direction. The first linear modules on both sides are connected to moving beams and synchronously drive the moving beams to reciprocate along the conveying direction of the paper laying conveyor line. Several grippers for holding the paper ends are distributed at intervals on the moving beams.

[0016] Optionally, the cutting assembly includes a second linear module located at the paper outlet of the release paper roll and arranged along the width direction of the release paper roll. The second linear module is equipped with a cutting blade, which is driven to cut the pulled-out release paper laterally.

[0017] Optionally, a stop block is installed on the paper-laying conveyor line to limit one end of the glass, which is used to determine the position of the glass at the paper-laying station.

[0018] Optionally, the first transfer mechanism includes a flipping shaft disposed between the glass unloading roller and the paper laying conveyor line. Multiple flipping arms extend from the surface of the flipping shaft. The flipping arms are aligned along the axial direction and evenly distributed in each radial plane. The flipping arms are provided with clamping grooves for holding single pieces of glass.

[0019] Optionally, the conveying direction of the glass sheet unloading roller conveyor is perpendicular to the conveying direction of the paper laying conveyor line, and the tilting arm travels through the gap between the conveying rollers of the glass sheet unloading roller conveyor and the gap between the conveyor belts of the paper laying conveyor line.

[0020] Optionally, the second transfer mechanism includes a robotic arm positioned between the paper delivery line and the stacking platform. The end of the robotic arm is equipped with a mounting frame, on which several suction cups are distributed. Each suction cup is used to simultaneously hold the separating paper segment and the glass.

[0021] Optionally, a contact switch is provided on the mounting bracket and on one side of the suction cup.

[0022] Optionally, a transfer trolley is also included. The stacking platform is equipped with a base frame for stacking glass, and the transfer trolley is located on one side of the stacking platform to support the fully loaded base frame.

[0023] On the other hand, the present invention adopts the following technical solution:

[0024] A method for laying glass paper, based on the aforementioned glass paper laying line, includes the following steps:

[0025] Step 1: The first transfer mechanism transfers glass sheets one by one from the glass unloading roller conveyor to the paper laying conveyor line;

[0026] Step 2: The paper-laying conveyor line transports the glass to the paper-laying station;

[0027] Step 3: The paper-pulling assembly pulls the paper end of the release paper roll so that the release paper covers the glass and the paper end is aligned with the end of the glass.

[0028] Step 4: Cut the components. Cut the pulled-out release paper according to the size of the glass, and place the release paper pieces on the upper surface of the glass.

[0029] Step 5: The second transfer mechanism transfers the glass with release paper sections laid on it from the paper-laying station to the stacking platform, so that each piece of glass is stacked and release paper is laid between adjacent pieces of glass.

[0030] In summary, the beneficial effects of the present invention are that the glass paper laying line and paper laying method realize the automated paper laying action of batch glass, which has the advantages of precise and simple action, low waste paper rate, good paper laying effect and high paper laying efficiency, and can be connected to the glass unloading production line, optimize the layout of the paper laying line and reduce the space occupied by the equipment.

The technical solutions of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] Please see Figure 1 and Figure 2 As shown, this preferred embodiment provides a glass sheet laying line that can be connected to an existing production line to complete a series of actions including production, sheet unloading, and stacking. Specifically, it includes a glass sheet unloading roller conveyor 1, a sheet laying conveyor line 2, a first transfer mechanism 3, a sheet laying mechanism 4, a stacking platform 5, and a second transfer mechanism 6.

[0051] Among them, the glass unloading roller conveyor 1 transports finished glass sheets of the target specifications one by one on the production line.

[0052] Among them, the paper-laying conveyor line 2 is located on one side of the glass unloading roller conveyor 1 and is used to transport the glass to the paper-laying station.

[0053] The first transfer mechanism 3 is used to transfer glass sheets one by one from the glass unloading roller 1 to the paper laying conveyor 2.

[0054] Preferably, see details. Figure 3 The first transfer mechanism 3 here includes a flipping shaft 31 disposed between the glass unloading roller 1 and the paper laying conveyor 2. Multiple flipping arms 32 extend from the surface of the flipping shaft 31. The flipping arms 32 are aligned along the axial direction and evenly distributed in each radial plane. The flipping arms 32 are provided with clamping grooves 33 for holding single pieces of glass. Here, four flipping arms 32 are arranged in the radial plane as an example, but it is not limited to this.

[0055] Specifically, the conveying direction of the glass sheet lower roller conveyor 1 is perpendicular to the conveying direction of the paper laying conveyor line 2. The tilting arm 32 travels through the gap between the conveying rollers of the glass sheet lower roller conveyor 1 and the gap between the conveyor belts of the paper laying conveyor line 2, making full use of the space and not affecting the conveying.

[0056] This allows for a change in the glass flow direction, reducing the floor space occupied by the paper-laying conveyor line 2 and the glass unloading roller conveyor 1. Furthermore, the flipping transfer method has a material storage function and does not affect the feeding and paper-laying rhythm.

[0057] The paper-laying mechanism 4 is located at the paper-laying station and includes a release paper roll 41, a paper-pulling assembly, and a cutting assembly. The release paper roll 41 is located above the glass on the paper-laying conveyor line 2. The paper-pulling assembly is used to clamp the paper end of the release paper roll 41 and pull it out along the glass conveying direction so that the paper end is aligned with the end of the glass. The cutting assembly is used to cut the release paper roll 41 according to the size of the glass to form release paper segments laid on the glass.

[0058] For details, see Figure 4 The paper pulling assembly includes first linear modules 42 located on both sides of the paper laying conveyor line 2 and arranged along the conveying direction. The first linear modules 42 on both sides are connected to moving beams 43 and synchronously drive the moving beams 43 to reciprocate along the conveying direction of the paper laying conveyor line 2. Several grippers 44 for clamping the paper ends are distributed at intervals on the moving beams 43.

[0059] See details Figure 5 The cutting assembly includes a second straight module 45 located at the paper outlet of the release paper roll 41 and arranged along the width direction of the release paper roll 41. The second straight module 45 is provided with a cutting blade 46, and the cutting blade 46 is driven to cut the pulled-out release paper laterally.

[0060] Specifically, see details. Figure 6 The paper-laying conveyor line 2 is equipped with a stop block 21 that limits one end of the glass to determine the position of the glass at the paper-laying station. It should be noted that since the release paper does not completely adhere to the glass when it is stretched and before it is cut, aligning the paper end with the glass end vertically cannot guarantee that the final size of the release paper will be exactly the same as that of the glass. Therefore, the front and rear positions of the stop block 21 relative to the cutting assembly need to be calculated in advance.

[0061] The stacking platform 5 is located on one side of the paper conveying line 2 and is used to stack glass. In particular, the stacking platform 5 is equipped with a base frame 8 for stacking glass, so the stacking platform 5 also has the ability to transfer loads, making it easy to replace the fully loaded base frame 8.

[0062] The second transfer mechanism 6 is used to transfer the glass with the release paper on the paper-laying station to the stacking platform 5.

[0063] Specifically, the second transfer mechanism 6 includes a robotic arm 61 located between the paper delivery line 2 and the stacking platform 5. The end of the robotic arm 61 is provided with a mounting frame 62, and a number of suction cups 63 are distributed on the mounting frame 62. Each suction cup 63 is used to simultaneously pick up the separating paper segment and the glass.

[0064] It should be noted that the release paper here is breathable. When the suction cup 63 has sufficient adsorption force, the suction cup 63 can adhere to the glass through the release paper.

[0065] Specifically, see details. Figure 7 A contact switch 64 is provided on the mounting bracket 62 and on one side of the suction cup 63. This contact switch 64 contacts the release paper on the upper surface of the glass and triggers the suction cup 63 to work and stop according to the contact stroke, so as to realize the picking and putting of the glass and the release paper.

[0066] In addition, the glass paper laying line also includes a transfer trolley 7, which is located on one side of the stacking platform 5 and is used to support the fully loaded base frame 8.

[0067] In this regard, this embodiment also provides a glass paper laying method, based on the above-mentioned glass paper laying line, which includes the following steps:

[0068] Step 1: The first transfer mechanism 3 transfers the glass sheets on the glass unloading roller 1 to the paper laying conveyor line 2 one by one.

[0069] Specifically, the glass on the glass lower sheet roller 1 is clamped by the flipping arm 32 on the same axis, and then the glass is flipped over and placed on the paper laying conveyor line 2 after the flipping arm 32 rotates.

[0070] Step 2: Paper-laying conveyor line 2 transports the glass to the paper-laying station.

[0071] Specifically, the stop block 21 stops the glass to ensure that the glass reaches the target paper-laying position.

[0072] Step 3: The paper-pulling assembly pulls the paper end of the release paper roll 41 so that the release paper covers the glass and the paper end is aligned with the end of the glass.

[0073] Specifically, the gripper 44 clamps the end of the release paper roll 41 and pulls the paper along the conveying direction of the paper laying conveyor line 2, so that the release paper is pre-covered on the glass so that the release paper can be cut according to the size of the glass.

[0074] Step 4: Cut the components. Cut the pulled-out release paper according to the size of the glass, and place the release paper segments on the upper surface of the glass.

[0075] Specifically, the shearing blade 46 is used to cut the stretched and taut release paper horizontally, so that the release paper section falls onto the glass, and the clamps 44 are released so that the release paper section lies flat on the glass surface.

[0076] Step 5: The second transfer mechanism 6 transfers the glass with release paper sections laid on the paper-laying station to the stacking platform 5, so that each piece of glass is stacked and release paper is laid between adjacent pieces of glass.

[0077] Specifically, the robotic arm 61, in conjunction with the suction cup 63, performs the actions of picking up and transporting the glass and release paper segments to complete the stacking. Furthermore, the fully loaded base can be transferred by the transfer trolley 7 to replace the empty base, achieving orderly material unloading and reducing the intensity of manual labor.

[0078] In summary, the above-mentioned glass paper-laying line and method realize automated paper-laying for batch glass production. It has the advantages of precise and simple operation, low waste paper rate, good paper-laying effect, and high paper-laying efficiency. It can also be connected to the glass unloading production line, optimize the layout of the paper-laying line, and reduce the space occupied by the equipment.

[0079] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
