Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide an automatic alignment type paper mounting machine to solve the problems existing in the prior art, realize automatic alignment of surface paper and base paper, and improve mounting efficiency and mounting quality.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 4As shown, the present embodiment provides an automatic alignment paper mounting machine, comprising a paper supply module, a face paper conveying module 3, a bottom paper conveying module 5, a photoelectric detection module and a laminating processing module, wherein the paper supply module is used to supply a single face paper 10 to the face paper conveying module 3, and to supply a single bottom paper 9 to the bottom paper conveying module 5, the laminating processing module is arranged near the output end of the face paper conveying module 3 and the output end of the bottom paper conveying module 5, and is used to laminate the single face paper 10 and the single bottom paper 9 to form a laminating paper 11, the output ends of the face paper conveying module 3 and the bottom paper conveying module 5 are both provided with a front gauge correction module 12, and the two groups of front gauge correction modules 12 can be used to correct the single face paper 10 and the single bottom paper 9 in the front and rear directions respectively, so as to ensure that the single face paper 10 and the single bottom paper 9 are aligned up and down, and to achieve smooth laminating, thereby ensuring that the produced laminating paper 11 meets the standard, and the length direction of the face paper conveying module 3 A plurality of photoelectric detection modules are installed on the top and in the length direction of the bottom paper conveying module 5, and each photoelectric detection module and each front gauge correction module 12 are electrically connected to a control module. The photoelectric detection module is used to detect the position signal of the single face paper 10 and the single bottom paper 9 to realize automatic real-time detection of the position of the single face paper 10 and the single bottom paper 9. The detected position signal can be transmitted to the control module, and the control module can automatically compare the position signal detected by each photoelectric detection module to determine the relative position of the single face paper 10 and the single bottom paper 9, and then control each front gauge correction module 12 to perform front gauge correction on the single bottom paper 9 or the single face paper 10 through the control module, so that the single bottom paper 9 and the single face paper 10 are aligned in the vertical direction, realizing automatic alignment of the single face paper 10 and the single face paper 10, ensuring that the single face paper 10 and the single bottom paper 9 can be smoothly attached, and improving product quality and production efficiency.

[0027] Specifically, the paper supply module includes a face paper supply unit and a bottom paper supply unit. The face paper supply unit is arranged at the input end of the face paper conveying module 3, and is used to supply a single face paper 10 to the face paper conveying module 3. The bottom paper supply unit is arranged at the input end of the bottom paper conveying module 5, and is used to supply a single bottom paper 9 to the bottom paper conveying module 5, thereby enabling the lamination of a single face paper 10 and a single bottom paper 9.

[0028] The face paper supply unit is a face paper flyer 1, and the bottom paper supply unit is a bottom paper flyer 2, which can realize stable conveyance of a single face paper 10 and a single bottom paper 9, and can be stopped for replacement at any time.

[0029] The facial paper conveying module 3 includes a plane section 31 and an inclined section 32. The first end of the plane section 31 is an input end, which is used to receive the single facial paper 10 conveyed by the facial paper supply unit. The second end of the plane section 31 is connected to the upper end of the inclined section 32. The lower end of the inclined section 32 is an output end, which is used to output the single facial paper 10 to the laminating processing module for laminating with the single base paper 9.

[0030] The plane section 31 is provided with a bridge correction module 4, and the bridge correction module 4 can perform stacking and side correction of the single face paper 10 during the conveying process, ensuring that the single face paper 10 can be accurately aligned with the single base paper 9 in the lateral direction, and then smoothly mounted. In addition, in order to ensure smooth correction, a paper pressing steel ball can be set on the inclined belt in the conveying direction, and the paper pressing steel ball presses on the single face paper 10 on the conveying belt to generate a lateral force on the single face paper 10, so that the single face paper 10 leans to one side during the travel, that is, lateral correction is performed during the travel. Multiple single face papers 10 are arranged and stacked in a shingled manner, thereby ensuring the stable transportation of the single face paper 10.

[0031] In every two adjacent single tissue papers 10, the first end of the single tissue paper 10 located at the rear is pressed against the second end of the single tissue paper 10 located at the front. This arrangement can prevent the single tissue paper 10 from deviating or falling during transportation to a certain extent.

[0032] The photoelectric detection module is a laser sensor. Two laser sensors are provided on the inclined surface section 32, which are a first laser sensor 13 and a second laser sensor 14. The first laser sensor 13 is installed in the middle of the inclined surface section 32, and the second laser sensor 14 is installed near the lower end of the inclined surface section 32. The second laser sensor 14 is arranged near the corresponding front gauge correction module 12 and is located in front of the corresponding front gauge correction module 12. A laser sensor is provided on the bottom paper conveying module 5, which is a third laser sensor 15. The third laser sensor 15 corresponds to the second laser sensor 14 in the vertical direction.

[0033] When the single sheet of facial paper 10 is conveyed to the first laser sensor 13, the first laser sensor 13 detects the position signal of the single sheet of facial paper 10 and transmits it to the control module. The control module controls the bottom paper conveying module 5 to start conveying the single sheet of bottom paper 9. The control module calculates the speed ratio of the single sheet of facial paper 10 and the single sheet of bottom paper 9 according to the conveying speed of the single sheet of facial paper 10 and the conveying speed of the single sheet of bottom paper 9. When the single sheet of bottom paper 9 is conveyed to the third laser sensor 15 and the single sheet of facial paper 10 is conveyed to the position of the second laser sensor 14, the control module calculates the relative position of the single sheet of facial paper 10 and the single sheet of bottom paper 9 according to the position signals detected by the second laser sensor 14 and the third laser sensor 15, and controls the servo front gauge correction wheels 121 of the two front gauge correction modules 12 to adjust the front and rear positions of the single sheet of facial paper 10 and the single sheet of bottom paper 9 respectively, so that the front gauges of the single sheet of facial paper 10 and the single sheet of bottom paper 9 are aligned by ±0.5mm.

[0034] The specific calculation principle involved in the control module in this embodiment is:

[0035] Assume that the distance between the first laser sensor 13 and the second laser sensor 14 is length A, and length A is a known quantity;

[0036] Assume that the distance between the base paper flyer 2 and the third laser sensor 15 is length B, and the length B is a known quantity;

[0037] Assume that length A is converted to length A′ according to the reference ratio of length B, and length A′ is an unknown quantity;

[0038] Lengthen the length A and separate it, and make A=C+C′, and C=B, so that C′=AC=AB;

[0039] Since the single sheet of facial paper 10 is transported in overlapping sheets in this embodiment, the transport speed corresponding to the length A is slower than the transport speed corresponding to the length B, and when used for single sheets of facial paper 10 of different lengths, the transport speed corresponding to the length A is inconsistent with the transport speed corresponding to the length B. Therefore, the control module is designed to use the transport speed corresponding to the length B as a reference, and convert the length A to the reference of the length B to obtain the converted length A'. At the same time, the control module ultimately aims to make the single sheet of facial paper 10 and the single sheet of bottom paper 9 correspond to each other at the second laser sensor 14 and the third laser sensor 15. Therefore, the control module calculates the converted length A' into the length C and the length C' through software calculation. Since the length C and the length B are equal in value, the length C' is the length of delayed paper delivery. At the same time, according to the above calculation, the servo front gauge correction wheel 121 of the corresponding front gauge correction module 12 can also be controlled to perform front gauge correction on the single sheet of facial paper 10 or the single sheet of bottom paper 9 to ensure that the output single sheet of facial paper 10 and the single sheet of bottom paper 9 correspond to each other in the vertical direction.

[0040] The base paper conveying module 5 is provided with a paper feed roller 51, which is arranged between the paper supply module and the laminating processing module, and is used to convey a single base paper 9 to ensure that the single base paper 9 can be output forward stably to avoid problems such as wrinkles and offsets.

[0041] The laminating processing module includes a gluing unit 6, a laminating unit 7 and a pressing unit 8 which are arranged in sequence along the conveying direction of the single base paper 9. The gluing unit 6 is arranged close to the paper feeding roller 51, and is used to glue the surface of the single base paper 9 output by the paper feeding roller 51. The laminating unit 7 is arranged close to the output end of the face paper conveying module 3, and is used to laminarize the single face paper 10 output by the face paper conveying module 3 and the single base paper 9 after being glued by the gluing unit 6. The pressing unit 8 is used to press the single face paper 10 and the single base paper 9 after being laminarized by the laminating unit 7, so as to finally make the single face paper 10 and the single base paper 9 stably laminarized together.

[0042] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
