Description

Technical Field

[0001] This utility model belongs to the field of book processing technology, specifically relating to a book parameter measuring device. Background Technology

[0002] Libraries and bookstores typically have a large number of books, making the identification process for managing book storage, borrowing, and returning quite laborious. Relying solely on ISBN numbers or titles for identification is prone to errors. Therefore, to manage books more efficiently and conveniently, with the development of automation and intelligent systems, libraries often use assembly line operations, employing robotic arms to print markings (such as access codes and stamps) or affix RFID tags to relevant pages of each book. However, before performing these tasks, the robotic arms need to know the relevant dimensional parameters of the books (such as length and thickness) to ensure accurate positioning during operation, thus ensuring high-quality marking or tagging.

[0003] Currently, the main technology for measuring book thickness parameters uses image recognition systems, which capture images of the book spine using a CCD camera. This system can directly calculate the number of pixels contained within a pulse width of the image, thereby obtaining the book's parameters. However, this method has the following problems: Because books are in a free state on the assembly line, they are prone to dimensional distortion due to loose pages or local bending. Furthermore, CCD cameras are limited by two-dimensional imaging and cannot accurately measure book parameters under three-dimensional deformation. The obtained book parameters are inaccurate, which in turn affects the positioning accuracy of the robotic arm. This can lead to abnormalities in printed markings or affixed labels, such as unclear or incomplete printed markings due to the robotic arm being positioned too high, or labels easily falling off. Utility Model Content

[0004] The purpose of this invention is to provide a book parameter measuring device that improves the measurement accuracy of book parameters during assembly line operations, facilitating subsequent book processing, such as printing labels or affixing tags.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Please see Figure 1 , Figure 2 and Figure 7 The present invention provides a book parameter measuring device, comprising: a folding component 2, a pressing component 3, and a measuring component 4.

[0038] Thickness measuring component 4 is slidably disposed above assembly line 1; pressing component 3 is disposed above assembly line 1 and has a measuring window 322 for measuring thickness; edge-aligning component 2 is disposed on assembly line 1; edge-aligning component 2 is used for adjusting the edges of book 5 so that the pressing component 3 can hold book 5; thickness measuring component 4 is used for measuring the thickness parameters of book 5. Specifically, in this embodiment, assembly line 1 is a prior art roller conveyor mechanism. Rollers 11 are rotatably mounted on support frames 12 on both sides of the top of the conveyor frame through roller bearings. A gap 111 is formed between adjacent rollers 11. Rollers 11 are connected at their ends by a synchronous belt 13. Servo motor 14 is connected to roller 11 through synchronous belt 13. Driven by servo motor 14, roller 11 can rotate, thereby achieving the purpose of conveying book 5. In this utility model, before the edge-aligning component 2 is adjusted, book 5 may be tilted due to vibration or other factors, so its length is initially measured. The equipment or method for initially measuring the length of book 5 includes, but is not limited to, the following equipment or methods. For example, the equipment is an existing image recognition system, which includes a CCD camera 46 and a controller. The CCD camera 46 is positioned at the front end of production line 1 to photograph the book 5. The CCD camera 46 can directly count the number of pixels contained within the pulse width of the image to obtain the length of the book 5, thus initially acquiring the length parameter of the book 5. The device for initially measuring the length of the book 5 moving in production line 1 can also use a first infrared measuring light curtain sensor 45. The first infrared measuring light curtain sensor 45 is installed above the junction of production line 1 and the previous process and is electrically connected to the PLC controller. It consists of a transmitter and a receiver. The transmitter emits an invisible infrared beam, forming a light curtain. When the object being measured passes through the light curtain, it blocks the beam, causing the receiver to detect the interruption of the beam, thereby generating a signal. This signal is transmitted to the control and execution system to realize the detection and measurement of the object being measured. In use, the front end of the book 5 begins to block the beam when passing through the light curtain, and the beam resumes after the rear end of the book 5 passes through the light curtain, thus realizing the measurement of the book 5. Figure 5 Length measurement can also be calculated by multiplying the duration of the blockage by the transmission time. Figure 5 Length Measurement. The device for initially measuring the length of book 5 moving in production line 1 can also employ a combination of sensors and encoders. When book 5 passes the sensor, a timing is triggered. Combined with the production line speed recorded by the encoder, the length of book 5 is calculated. The length data of book 5 is fed back to the PLC controller. Based on this, the PLC controller controls production line 1 to move book 5 to a predetermined position and pause, so that the pressing component 3 can hold book 5 as centered as possible. The edge-aligning component 2 further adjusts the position and offset of book 5, aligning the spine or side of book 5 with the reference of the edge-aligning component 2, facilitating the pressing component 3's holding and the measurement component 4's accurate measurement of length and thickness.

[0039] This utility model discloses a book parameter measuring device. Book 5 is placed on the production line 1. First, the length of book 5 is initially measured to obtain its initial midpoint position. This allows the production line 1 to control the movement of the book 5's midpoint until it pauses directly below the center of the measuring window 322, facilitating the pressing component 3 to hold book 5 as centered as possible. Then, the edge-aligning component 2 is activated to adjust and restrict the position of book 5 horizontally, preventing it from shifting or tilting due to the pressing component 3 or equipment vibration on the production line 1. Next, the pressing component 3 is activated to press book 5. The pressing component 3 applies force perpendicular to book 5, engaging with the surface of the production line 1 to restrict book 5's movement vertically. The pressure from the pressing component 3 also helps to flatten and compact the pages of book 5, eliminating deformation. Finally, the thickness measuring component 4 is activated, measuring the length and thickness parameters of book 5 as it moves. Because the book 5 measures its length and thickness parameters under pressure, the measurement accuracy of the book 5 parameters can be improved. The pressing component 3 simulates the force applied by the robotic arm when printing or pasting labels on the book 5, thereby improving the quality of printing or pasting labels.

[0040] Further, please refer to Figure 5 , Figure 6 and Figure 7 The thickness measuring component 4 includes a thickness measuring instrument 41 and a drive component 42. The drive component 42 includes a measuring drive source 421, a first pulley 422, a second pulley 423, and a first belt 424. The measuring drive source 421 is installed at one end of the production line 1. The first pulley 422 is installed on the output shaft of the measuring drive source 421. The second pulley 423 is installed on the production line 1. The first pulley 422 and the second pulley 423 are connected by the first belt 424. The thickness measuring instrument 41 is installed on the first belt 424. Specifically, the first pulley 422 and the second pulley 423 are spaced apart. Preferably, the first pulley 422 is located at the beginning of the production line 1, and the second pulley 423 is located at the end of the production line 1. The lengths of the first pulley 422 and the second pulley 423 are sufficient for measuring books 5 of different lengths. Preferably, the measuring drive source 421 is a motor.

[0041] In use, after the book 5 passes through the edge-aligning component 2 and the pressing component 3, the book 5 is positioned and held. The measurement drive source 421 is activated, driving the first pulley 422 to rotate. Under the drive of the first belt 424, the second pulley 423 rotates synchronously. By starting the measurement drive source 421 in either forward or reverse direction, the first pulley 422 rotates in the opposite direction, and the first belt 424 moves back and forth between the first pulley 422 and the second pulley 423. The thickness measuring instrument 41 moves with the first belt 424, thereby measuring the thickness of the book 5 and feeding the thickness information back to the PLC controller. Preferably, the thickness measuring instrument 41 can be a laser displacement distance sensor, model FSD22-100; it can also be a laser rangefinder, model LDM-80H, which measures the thickness of the book 5 using emitted laser light when positioned above it; it can also be a second infrared light curtain sensor; or it can be any other device capable of measuring thickness or distance.

[0042] Furthermore, the drive assembly 42 also includes a first guide rail 425 and a first slider 426. The first guide rail 425 is mounted on the production line 1, and the thickness measuring instrument 41 is mounted on the first slider 426. The first slider 426 moves along the first guide rail 425. Specifically, the first guide rail 425 is bolted to the production line 1 along its length. The first guide rail 425 has a first groove 427, and the first slider 426 has a first groove 428 that matches the shape of the first guide rail 425. The first slider 426 moves oriented and stably along the guide rail. The thickness measuring instrument 41 also includes a measuring base 411. One end of the measuring base 411 is bolted to the first slider 436, and the other end is connected to the first belt 424. The thickness measuring instrument 41 is mounted on the measuring base 411.

[0043] Further, please refer to Figure 3 and Figure 4The pressing assembly 3 includes a pressing drive source 31 and a pressure plate 32. The pressure plate 32 is installed at the output end of the pressing drive source 31 and is located above the edge-aligning assembly 2. The pressure plate 32 includes an upper pressure plate 323, a lower pressure plate 324, and a buffer structure 327. The upper pressure plate 323 is connected to the output end of the pressing drive source 31, and the lower pressure plate 324 is connected to the upper pressure plate 323 through the buffer structure 327. Specifically, the production line 1 is provided with a mounting bracket 15. The pressing drive source 31 is installed on the outside of the mounting bracket 15 by bolts, and its output shaft is perpendicular to the production line 1. The pressure plate 32 is installed at the output end of the pressing drive source 31 through an adapter plate 321. The pressure plate 32 is parallel to the production line 1. The pressing drive source 31 drives the pressure plate 32 to apply downward pressure to the book 5, making the book 5 flat and the pages compact, thus improving the accuracy of measuring the thickness of the book 5. The buffer structure 327 includes an elastic element 325 and a connecting post 326. One end of the connecting post 326 is mounted on the lower pressure plate 324, and the other end is sleeved in the upper pressure plate 323. The elastic element 325 is sleeved on the outside of the connecting post 326, and both ends of the elastic element 325 abut against the upper pressure plate 323 and the lower pressure plate 324, respectively. The upper pressure plate 323 has multiple through holes, and the connecting post 326 slides through the interior of each through hole. A nut is threaded to the top of the connecting post 326, and the bottom end of the connecting post 326 is fixedly mounted on the lower pressure plate 324 by welding. With the above structure, the force exerted on the book 5 by the lower pressure assembly 3 is buffered, and the force is applied to the book 5 smoothly. During the measurement process, even if the book 5 is subjected to external vibration force, it is always in pressure contact with the book 5 under the action of the elastic element 325, which enhances the accuracy of measuring the thickness of the book 5. Moreover, when subjected to pressure error from the lower pressure drive source 31, the buffer structure 327 can compensate for the force applied to the book 5. Preferably, the elastic element 325 is a spring, and there are four elastic elements 325, which are respectively arranged at the four corners of the lower pressure plate 324. The lower pressure drive source 31 is one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. By setting the output pressure of the lower pressure drive source 31 to match the pre-obtained pressure applied by the robotic arm, the book 5 is pressed.

[0044] Further, please refer to Figure 3 A measuring window 322 is provided on the surface of the pressure plate 32 facing the edge-aligning component 2. The measuring window 322 is arranged along the width direction of the pressure plate 32, and when the thickness measuring instrument 41 passes the pressure plate, the measuring window 322 is located directly below the thickness measuring instrument 41. Specifically, the measuring window 322 is a through measuring groove, and the shape of the through measuring groove is one of U-shape, O-shape, square, etc. By setting the measuring window 322, the thickness measuring instrument 41 moves along the measuring window 322 to measure the thickness of the book 5, thereby improving the accuracy of measuring the thickness of the book 5.

[0045] like Figure 8As shown, a laser displacement ranging sensor, if used, mainly consists of a laser emitter, a receiver, a signal processing unit, an output interface, and a display unit. The laser emitter emits a laser beam that illuminates the surface of the target object. After reflection from the object's surface, the laser beam is received by the receiver. By measuring the time difference or phase difference between laser emission and reception, the distance between the sensor and the target object can be calculated. This method is commonly used to measure distances (length or thickness). In practical applications, a PLC controller is electrically connected to the laser displacement ranging sensor, and the PLC controller stores and processes the distance values. The pressure plate 32 holds the book 5, which is relatively flat. The thickness measuring instrument 41 and the measurement drive source 421 are activated. The measurement drive source 421 drives the measuring instrument to move along the production line 1. When the laser irradiates the surface of the production line, the surface of the book 5, and the surface of the pressure plate 32, the laser displacement ranging sensor will sequentially measure the following height values ​​H1, H2, H3, H4, H5, H6, and H7 after reflection from each surface. H1 and H7 are the heights of the production line 1 surface, H2 and H6 are the heights of the book 5 surface on both sides of the pressure plate 32, H3 and H5 are the heights of the pressure plate 32 surface, and H4 is the height of the book 5 surface at the measurement window 322. The thickness is measured at position H4 to obtain a more accurate thickness of the book 5. The thickness of the book 5 is directly obtained from the laser displacement ranging sensor and uploaded to the PLC controller, or the PLC controller calculates the H1 and H4 values ​​measured when the laser displacement ranging sensor moves. The difference between H4 and H1 is the thickness of the book 5. Meanwhile, the thickness measuring instrument 41 moves L1 to the junction of H1 and H2, and L2 to the junction of H6 and H7. Thus, the length of book 5 can be obtained as L3 = L2 - L1. The method for obtaining L2 or L1 is as follows: The laser displacement ranging sensor pauses at the junctions of H1 and H2 and H6 and H7. The rotation speed of the measurement drive source 421 is preset, meaning the movement v of the laser displacement ranging sensor is constant. The time t1 for passing the junction of H1 and H2 and the time t2 for passing the junction of H6 and H7 are recorded. L3 = t2*v - t1*v; or when the driving source 421 is a motor, record the number of rotations n1 at the junction of H1 and H2, and the number of rotations n2 at the junction of H6 and H7 respectively. L3 = C*n2 - C*n1, where C is the circumference of the motor shaft. b: Taking an object on the assembly line 1 as a reference, the distance the laser displacement distance sensor moves to the junction of H1 and H2 is L1, and the distance it moves to the junction of H1 and H2 is L2. The length of the book 5 can be obtained by using the difference in the moving distances. L3 = L2 - L1.

[0046] If a second infrared light curtain sensor is used, when the light curtain shines on the surface of the production line, the surface of book 5, and the surface of the pressure plate 32, the receiver cannot receive all or part of the light signal when the light curtain is blocked or interrupted by each surface, thus generating a trigger signal. The book length and thickness parameters are obtained by detecting and analyzing the different received light signals. Because book 5 is adjusted by the edge-aligning component 2 and held by the pressing component 3, a more accurate book length can be obtained, and the thickness and length information is fed back to the PLC controller. Simultaneous measurement of thickness and length improves measurement efficiency.

[0047] Furthermore, the pressing assembly 3 also includes a guide structure 33, which includes a guide seat 331 and a guide rod 332. The guide seat 331 has a guide hole 333 and a working cavity through it. The pressing drive source 31 is installed in the working cavity, and its output end can extend and retract along the guide seat 331. One end of the guide rod 332 is connected to the pressure plate 32, and the other end slides in the guide hole 333. Specifically, the guide rod 332 is welded to the lower surface of the adapter plate 321, and the guide rod 332 is parallel to the output shaft of the pressing drive source 31. Preferably, there are two sets of guide rods 332. In use, the output end of the pressing drive source 31 extends or retracts from the guide seat 331. With the cooperation of the guide structure 33, the pressure plate 32 moves stably along a predetermined movement trajectory, thereby applying a predetermined pressure to the book 5 or releasing the book 5.

[0048] Please see Figure 1 and Figure 7 Furthermore, the edge-gathering assembly 2 includes a fixed clamp 21, a movable clamp 22, and an edge-gathering drive assembly 23. The fixed clamp 21 and the movable clamp 22 are installed on opposite inner sides of the assembly line 1. The movable clamp 22 is connected to the output end of the edge-gathering drive assembly 23, which is installed on the assembly line and drives the movable clamp 22 to move closer to or away from the fixed clamp 21. Specifically, the edge-gathering assembly 2 is located below the pressing assembly 3. The edge-gathering assembly 2 can adopt a single-sided shaping plate as described in patent application number CN202022190172.3, and a single-sided shaping power mechanism for driving the single-sided shaping plate to move perpendicular to the conveying direction. The fixed clamp 21 and the movable clamp 22 are vertical bars or baffles arranged side by side along the conveying direction of the book 5. Preferably, both the fixed clamp 21 and the movable clamp 22 are provided with clamping plates 222 and multiple clamping strips 223. The clamping plates 222 and the clamping strips 223 are integrally formed, and the clamping strips 223 are disposed in the gap 111 between adjacent rollers 11. The fixed clamp 21 is fixedly installed on the inner side of the assembly line 1 by bolts, serving as a reference for the edge alignment of books 5.

[0049] Further, the edge-returning drive assembly 23 includes an edge-returning drive source 231 and a transmission mechanism 232. One end of the transmission mechanism 232 is mounted on the output end of the edge-returning drive source 231, and the other end is connected to the movable clamp 22. Preferably, the edge-returning drive source 231 is an electric push rod, a pneumatic push rod, or a hydraulic push rod. The transmission mechanism 232 is a pulley mechanism or a sprocket mechanism. In one embodiment, the transmission mechanism 232 is a pulley mechanism, which includes a third pulley 233, a second belt 234, and a fourth pulley 235. The output shaft of the edge-returning drive source 231 is connected to the third pulley 233, and the fourth pulley 235 is connected to the third pulley 233 via the second belt 234. The movable clamp 22 is mounted on the second belt 234 and moves with the movement of the second belt 234. In other embodiments, it can also be a sprocket mechanism, the principle of which is the same as that of the pulley mechanism. In use, the edge-aligning drive source 231 is activated, driving the third pulley 233 to rotate. Under the drive of the second belt 234, the fourth pulley 235 rotates synchronously. Through the forward and reverse start of the edge-aligning drive source 231, the second belt 234 moves back and forth between the third pulley 233 and the fourth pulley 235, thereby driving the movable clamp 22 to move closer to or away from the fixed clamp 21. When it moves closer, it clamps the book 5.

[0050] Furthermore, the edge-returning drive assembly 23 also includes a second guide rail 236 and a second slider 237. The second guide rail 236 is mounted on the assembly line 1, and the movable clamp 22 is mounted on the second slider 237, which moves along the second guide rail 236. Specifically, the second guide rail 236 is bolted to the assembly line 1 along its width direction and is parallel to the output shaft of the edge-returning drive source 231. The second guide rail 236 has a second groove, and the second slider 237 has a second groove that matches the shape of the second guide rail 236. The second slider 237 moves oriented and stably along the second guide rail 236. The movable clamp 22 also includes a clamping seat 221, one end of which is bolted to the second slider 237, and the other end is connected to the second belt 234.

[0051] Furthermore, it also includes a width measuring component 6, which is disposed inside the production line 1, facing the edge-aligning component 2 in the edge-aligning movement direction. Specifically, the width measuring component 6 is a width measuring instrument, which is mounted on the mounting bracket 15. Preferably, the width measuring instrument is a first photoelectric sensor, and the measuring end of the first photoelectric sensor is slightly closer to the movable clamp 22 than the fixed clamp 21. The first photoelectric sensor is model E3ZG-T61 and is electrically connected to the PLC controller. The photoelectric sensor is based on the photoelectric effect principle and mainly consists of three parts: a light source, an optical path, and a light receiver. Its basic principle is to convert light signals into electrical signals. In the optical path, the light emitted by the light source is reflected by the object, and the reflected light enters the light receiver. The light receiver converts the light signal into an electrical signal and outputs it to measure the distance of the object. In use, the first photoelectric sensor illuminates the surface of the movable clamp 22. The distance L4 from the movable clamp 22 to the first photoelectric sensor is recorded and uploaded by the PLC controller. The edge-returning drive component 23 drives the movable clamp 22 to move towards the fixed clamp 21, stopping after clamping the book 5. The moving distance L5 can be measured by the first photoelectric sensor. By calculating the length of the book 5, L6 = L4 - L5, the width of the book 5 can be measured relatively accurately, and the width information is fed back to the PLC controller. Preferably, there are multiple sets of the first photoelectric sensor, four sets in this embodiment, which measure the moving distance of the movable clamp 22 from above and below the production line 1, respectively. The width measurement data from multiple sets are evaluated and optimized to obtain accurate width parameters for the book 5.

[0052] This invention discloses a method and device for measuring book parameters. First, a folding component 2 horizontally restricts the movement of book 5, while a width measuring component 6 measures the width of book 5. A pressing component 3 vertically restricts the movement of book 5, and the pressure from the pressing component 3 flattens the book 5, compressing the pages to create a compact effect, simulating the thickness of book 5 under the pressure of a robotic arm stamping. A thickness measuring instrument 41 measures the thickness of book 5 while it is being pressed down, and simultaneously measures the length parameter by changing the thickness parameter, thereby improving the accuracy of book 5 thickness measurement and enhancing the quality of printed labels or affixed tags. A measuring window 322 is provided, and the thickness measuring instrument 41 moves along the measuring window 322 to measure the thickness of book 5, further enhancing the accuracy of the thickness measurement.
