Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper roll production, in particular to a paper roll conveying device. BACKGROUND

[0002] In the papermaking industry, a rewinder plays a vital role, which is responsible for rewinding the paper roll produced by the papermaking machine (referred to as the original paper roll). The rewinder mainly cuts the paper roll into the required width through the paper guide roll and the slitting mechanism, and then the accurately cut paper roll is carefully wound into a paper roll with a specified tightness and diameter according to the specific requirements of the customer.

[0003] However, the paper roll taken off the rewinder cannot directly flow into the market, and it still needs to be tested for specifications to ensure that each paper roll strictly meets the various specification data listed on the product certificate, among which the weight and width are the most critical factors. In the existing detection process, the paper roll is mainly weighed at the conveying device to ensure that its weight meets the standard; then the paper roll is conveyed to the predetermined conveying destination with the conveying device. At the conveying destination, the paper roll is directly packaged, however, at this packaging link, a potential problem emerges. Since the packaging paper itself has a certain thickness, when the scanning device tries to measure the width of the paper roll through the packaging paper, the data obtained is often disturbed by the thickness of the packaging paper, resulting in inaccurate measurement results. This error, although seemingly small, can have a significant impact on product compliance and customer satisfaction. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the present application provides a paper roll conveying device to solve the problem of inaccurate width of the scanned paper roll after packaging.

[0006] a conveying mechanism for conveying the paper roll;

[0007] a pair of width scanning heads, which are arranged on both sides of the conveying mechanism and face each other to measure the actual width of the paper roll.

[0008] Further, the width scanning head is a laser distance sensor.

[0009] Further, it further comprises a data processing module and a specification label scanning head corresponding to the specification label of the scanned paper roll; the specification label scanning head and the width scanning head are respectively connected with the data processing module in communication.

[0010] Further, the specification label scanning head is arranged above and / or on one side of the conveying mechanism.

[0011] Further, the paper roll conveying device further comprises a support frame, the support frame comprising support rods respectively standing on two sides of the conveying mechanism and a connecting rod connecting the two support rods and located above the paper roll on the conveying mechanism; the specification label scanning head is arranged on the support rod and / or the connecting rod.

[0013] Further, the conveying mechanism is a chain plate machine.

[0014] Further, the weight sensor of the chain plate machine is in communication connection with the data processing module.

[0015] Different from the prior art, the above technical solution can directly and accurately measure the width of the paper roll in the dynamic process of conveying the paper roll by arranging the width scanning head on both sides of the conveying mechanism, effectively avoiding the inaccuracy problem caused by scanning the width of the paper roll after packaging in the traditional method, thereby ensuring the accuracy and reliability of the measurement result, and improving the production efficiency and product quality.

[0041] Reference is made to Figures 1-3The utility model provides a kind of paper roll transmission device, by setting width scanning head 20 on the both sides of transmission mechanism 10, it can directly and accurately measure the width size of paper roll 30 in dynamic process of transmission, effectively avoids the inaccuracy problem caused by width scanning after paper roll 30 is packed in traditional method, to ensure the accuracy and reliability of measurement result, improve production efficiency and product quality.

[0042] In combination Figure 1 The following provides an embodiment of a paper roll transmission device, which comprises:

[0043] Transmission mechanism 10 for transporting paper roll 30;

[0044] A pair of width scanning heads 20 are arranged on the both sides of transmission mechanism 10 and the two width scanning heads 20 face each other to measure the actual width D of the paper roll.

[0045] The transmission mechanism 10 described above is used to transport paper roll 30, and the specific transmission structure is not limited, and various different transmission modes can be used to realize the transportation of paper roll 30, including but not limited to chain transmission, belt transmission and gear transmission, etc., according to different application scenarios and requirements, the most suitable transmission mode is selected to realize the efficient and stable transportation of paper roll 30. The above-mentioned width scanning head 20 is arranged on the both sides of transmission mechanism 10 and the two width scanning heads 20 face each other, so that the two width scanning heads 20 form a scanning area, ensuring that they can scan the width of the paper roll at the same time. When paper roll 30 moves with transmission mechanism 10, it enters the scanning area of the two width scanning heads 20, obtains the distance corresponding to the two width scanning heads 20 and paper roll 30, and then determines the actual width D of the paper roll by calculation based on the diagonal distance of the two width scanning heads 20 and the distance of the two width scanning heads 20 in the transmission direction.

[0046] The width scanning head 20 can be a laser ranging sensor, a high-precision camera, etc. In some embodiments, the width scanning head 20 is a laser ranging sensor. The laser ranging sensor emits a laser beam to the paper roll 30. The reflected signal is received by the laser ranging sensor, which is converted into the distance between the width scanning head 20 and the paper roll 30. Based on the distance between the two width scanning heads 20 and the distance between the two width scanning heads 20 in the conveying direction, the actual width D of the paper roll can be calculated. The laser ranging sensor has the advantages of high precision, long distance measurement, and no maintenance, etc. It is suitable for paper rolls 30 of various sizes, and can complete the measurement without contacting the paper roll 30, thereby avoiding errors and damage caused by contact. In some embodiments, the width scanning head 20 is a high-precision camera, which has high resolution and fast image processing capability, ensuring that the paper roll 30 can be clearly photographed. By using image processing technology, the camera captures the image of the paper roll 30 and extracts the contour information of the edge of the paper roll 30. Based on the distance between the two width scanning heads 20, the distance between the two width scanning heads 20 in the conveying direction, and the contour information, the actual width D of the paper roll can be calculated.

[0047] To improve the automation level of the paper roll 30 specification test, a data processing module 60 and a specification label scanning head 40 corresponding to the specification label of the paper roll 30 can also be included. The specification label scanning head 40 and the width scanning head 20 are respectively in communication connection with the data processing module 60.

[0048] The specification label scanning head 40 is used to scan the specification label of the paper roll 30 on the conveying mechanism 10 to obtain the specification data of the paper roll 30, and then transmit the specification data of the paper roll 30 to the data processing module 60. The specification label contains specification data, such as standard width, standard weight, etc. The specific form of the specification label is various, which can be numerical values of specification data, such as numerical values of standard width and standard weight, so that the specification label scanning head 40 can quickly and accurately capture these key information by optical recognition technology. In addition, it can also be in the form of encoding such as two-dimensional code and bar code, which has the advantages of large information capacity, high encoding density, and strong error correction capability, etc. It can store the specification data of the paper roll 30. The specification label scanning head 40 can identify and analyze these encodings such as two-dimensional code or bar code by using the built-in decoding algorithm, so as to obtain the specification data of the paper roll 30. The specification label scanning head 40 and the width scanning head 20 are respectively in communication connection with the data processing module 60, so that the data processing module 60 respectively receives the specification data of the paper roll 30 transmitted by the specification label scanning head 40 and the actual width D of the paper roll transmitted by the width scanning head 20, and compares whether the difference between the standard width of the paper roll in the specification data and the actual width D of the paper roll is less than a preset value. If yes, the actual width D of the paper roll is qualified, otherwise the actual width D of the paper roll is unqualified.

[0049] In order to facilitate the size label scanning head 40 to scan the size label of the paper roll 30, the size label of the paper roll 30 is usually made to face one side or above of the conveying mechanism 10. For this purpose, the size label scanning head 40 can be arranged above and / or on one side of the conveying mechanism 10. That is, the size label scanning head 40 is arranged above the conveying mechanism 10; or the size label scanning head 40 is arranged on one side of the conveying mechanism 10; or the size label scanning head 40 is arranged above and on one side of the conveying mechanism 10. Specifically, a support frame 50 can be arranged to fix the size label scanning head 40. In some embodiments, the support frame 50 includes support rods 501 respectively standing on both sides of the conveying mechanism 10 and a connecting rod 502 connecting the two support rods 501 and located above the paper roll 30 on the conveying mechanism 10; the size label scanning head 40 is arranged on the support rods 501 and / or the connecting rod 502, that is, the size label scanning head 40 is arranged on the connecting rod 502; or the size label scanning head 40 is arranged on the support rods 501; or the size label scanning head 40 is arranged on both the connecting rod 502 and the support rods 501.

[0050] Of course, in some embodiments, the actual weight of the paper roll 30 is obtained during the conveying of the paper roll 30, that is, a weight measuring element or structure, such as a weight sensor 101, can be arranged in the conveying mechanism 10; or a conveying mechanism 10 with a weight measuring function, such as a chain plate machine (with a weight sensor 101), is used. Taking the chain plate machine as an example, when the paper roll 30 is conveyed on the conveying mechanism 10, the weight sensor 101 can accurately measure and record the actual weight of the paper roll 30 in real time. This improves the automation and intelligence level of the conveying process and also helps to realize dynamic monitoring and management of the weight of the paper roll 30.

[0051] Referring to Figure 3 In order to improve the automation level of the paper roll 30 size test, the weight sensor 101 of the chain plate machine can also be in communication connection with the data processing module 60, so that the data processing module 60 receives the actual weight of the paper roll 30 transmitted by the weight sensor 101 of the chain plate machine; under the premise that the data processing module 60 receives the size data of the paper roll 30 transmitted by the size label scanning head 40, the data processing module 60 compares whether the difference between the standard weight of the paper roll 30 in the size data and the actual weight of the paper roll 30 is less than a preset value, if yes, the actual weight of the paper roll 30 is qualified, otherwise the actual weight of the paper roll 30 is unqualified.

[0052] Finally, it should be noted that the above embodiments have been described in the specification and drawings of the present application, but this does not limit the patent protection scope of the present application. Any equivalent structure or equivalent process replacement or modification based on the essential concept of the present application, using the content described in the specification and drawings of the present application, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
