Description

Technical Field

[0001] This invention relates to the field of book acquisition and editing technology, and in particular to a method and mechanism for labeling book spines. Background Technology

[0002] In libraries and bookstores, labels are often affixed to the spines of books to facilitate identification and categorization, and then scanned into the database. Label information typically includes details such as title, author, publisher, and ISBN number. This information helps readers better understand and select books, and also facilitates book management and indexing for institutions with large collections, such as libraries and bookstores. Searching the label information helps administrators quickly find and retrieve the book information they need.

[0003] Currently, except for a small number of books that require manual labeling, book labeling in large libraries is mostly done mechanically. For example, Chinese patent CN202220708165.4 discloses a book labeling mechanism and system for an intelligent automated library, which includes a labeling robot, a label-picking and labeling component, and a label-rolling component. This patent first uses the label-picking and labeling component to complete the conventional labeling action, that is, the labeling robot drives the label-picking and labeling actions. After being applied to the spine by the label-picking and labeling component, there are two possibilities: if the spine is thick enough, the label is completely applied to the spine surface; if the spine is thin, the label protrudes from the spine surface. This solution also includes a label-rolling component, which bends the label, causing the label protruding from the spine to be applied to the book cover on both sides of the spine.

[0004] The labeling roller in this patented solution has a fixed structure, and the labeling gap cannot be matched with different book thicknesses, thus limiting its applicability. Therefore, it is necessary to further improve the labeling mechanism. Summary of the Invention

[0005] To address the problem that existing labeling rollers are fixed and the labeling gap cannot be matched with the thickness of different books, thus limiting their applicability, a spine labeling mechanism is proposed, which is applicable to labeling books of different thicknesses.

[0006] A method for attaching labels to the spine of a book includes the following steps:

[0007] S1: Given that the label length is L, measure the book thickness H. If (LH) / 2 is less than W, where W is in the range of 2mm-5mm, then the book is transported to labeling point one via the conveyor platform; otherwise, the book is transported to labeling point two via the conveyor platform.

[0008] S2: Perform edge trimming on the books, pushing the spine of the books to the inner edge of the conveyor platform;

[0009] S3: Grab the label; if the book is located at labeling point one, paste the middle part of the label on the plane where the spine is located; if the book is located at labeling point two, paste the upper part of the label on the edge of the cover above the spine.

[0010] S4: If the book is located at labeling point one, paste the top and bottom of the label onto the cover at the top and bottom of the spine respectively; if the book is located at labeling point two, first paste the middle of the label onto the plane where the spine is located, and then paste the bottom of the label onto the edge of the cover below the spine.

[0011] Furthermore, between steps S2 and S3, a book-pressing step is included to fix the position of the book.

[0012] Furthermore, in step S4, if the book is located at labeling point two, the step also includes pressing the upper part of the label against the upper edge of the cover on the spine.

[0013] Furthermore, between S3 and S4, there is also a step of grasping the protective film; if the book is located at labeling point one, the middle part of the protective film is pasted onto the label on the plane where the spine is located; if the book is located at labeling point two, the upper part of the protective film is pasted onto the label on the edge of the cover above the spine.

[0014] Furthermore, in step S1, the front and back positions of labeling point one and labeling point two can be interchanged.

[0015] A spine labeling mechanism based on the above-mentioned spine labeling method includes a conveying platform, a robotic arm, and a label picking and labeling mechanism mounted on the robotic arm; a first labeling roller, a second labeling roller, and a first driving device are arranged side by side at a labeling position; a gap is left between the first labeling roller and the second labeling roller; the first driving device is used to drive the first labeling roller and the second labeling roller to move horizontally on the cover on the upper and lower sides of the spine, respectively.

[0016] At the labeling position, a third labeling roller, a fourth labeling roller, and a third driving device and a fourth driving device are respectively provided to drive the third labeling roller and the fourth labeling roller to move. The third labeling roller is parallel to the plane where the spine is located, and the fourth labeling roller is perpendicular to the plane where the spine is located. The labeling mechanism, driven by the robotic arm, affixes the upper part of the label to the cover edge on one side of the spine. The third labeling roller, driven by the third driving device, presses the middle part of the label onto the plane where the spine is located. The fourth labeling roller, driven by the fourth driving device, presses the lower part of the label onto the cover edge on the other side of the spine.

[0017] Furthermore, a stop is provided on one side of the conveying platform, and a clearance opening is provided on the stop. A clearance platform is provided on the conveying platform at the position corresponding to the clearance opening. It also includes a spine-aligning device for pushing one side of the book spine to the stop.

[0018] Furthermore, the edge-returning device includes a stop bar, a stop bar bracket, a slide rail mounting plate, and a second drive device. The stop bar is mounted on the stop bar bracket, the stop bar bracket is slidably mounted on the slide rail mounting plate, and the stop bar bracket is connected to the second drive device in a transmission connection.

[0019] Furthermore, a pad with the same height as the conveying surface of the conveying platform is provided at the clearance platform.

[0020] Furthermore, a book-pressing component for pressing the books is provided on the upper part of the conveyor platform.

[0021] Furthermore, it also includes a label pressing device, which includes a pressure plate, a guide rail and a guide rail bracket. The pressure plate is connected to the guide rail, and the guide rail bracket is provided with a guide groove that cooperates with the guide rail. A guide rod is movably connected between the pressure plate and the guide rail bracket, and a spring is fitted on the guide rod.

[0022] The principle of this invention is as follows: the label length is L, the book thickness is H, and if (LH) / 2 is less than W, where W is in the range of 2mm-5mm, the book is transported to the labeling point via a conveying platform; the robotic arm brings the label picking and labeling mechanism to the labeling point and drives the label picking and labeling mechanism to affix the center of the back of the label to the plane where the spine is located; then the first driving device drives the first labeling roller and the second labeling roller to move along the direction perpendicular to the plane where the spine is located, and using the gap between the first labeling roller and the second labeling roller, the upper and lower ends of the back of the label are pressed onto the cover of the upper and lower sides of the spine.

[0023] Conversely, the book is transported to labeling point two via a conveyor platform; the robotic arm brings the label-picking and labeling mechanism to labeling point two and drives the mechanism to affix the upper back of the label to the upper edge of the cover on the spine, i.e., the front of the book near the spine. Then, the third drive device drives the third labeling roller to move along a plane parallel to the spine. During the movement, the middle of the label is pressed onto the spine. Then, the third drive device drives the third labeling roller to reset. Next, the fourth drive device drives the fourth labeling roller to move along the bottom of the book perpendicular to the spine, pressing the lower back of the label onto the lower edge of the cover on the spine, i.e., the lower part of the book near the spine. Finally, the fourth drive device drives the fourth labeling roller to reset, completing the labeling process.

[0024] The beneficial effects of this invention are: 1. It can label books of different thicknesses and has a wide range of applications; 2. The books are transported horizontally, and the spine is fixed by the edge-aligning device and the book-pressing component during the labeling process, which improves the stability of the labeling.

[0034] The following description, in conjunction with embodiments, further illustrates a spine labeling method and spine labeling mechanism of the present invention.

[0035] A method for attaching labels to the spine of a book includes the following steps:

[0036] S1: Given that the label length is L, measure the book thickness H. If (LH) / 2 is less than W, where W is in the range of 2mm-5mm, then the book is transported to labeling point one via the conveyor platform; otherwise, the book is transported to labeling point two via the conveyor platform.

[0037] S2: Perform edge trimming on the books, pushing the spine of the books to the inner edge of the conveyor platform;

[0038] S3: Grab the label; if the book is located at labeling point one, paste the middle part of the label on the plane where the spine is located; if the book is located at labeling point two, paste the upper part of the label on the edge of the cover above the spine.

[0039] S4: If the book is located at labeling point one, paste the top and bottom of the label onto the cover at the top and bottom of the spine respectively; if the book is located at labeling point two, first paste the middle of the label onto the plane where the spine is located, and then paste the bottom of the label onto the edge of the cover below the spine.

[0040] Between steps S2 and S3, a book-pressing step is included to fix the book's position. Existing Chinese patent CN202220708165.4 describes a book labeling mechanism and system for an intelligent three-dimensional library. In this solution, the feeding mechanism includes a book-clamping seat and a feeding drive module that moves the clamping seat horizontally. This mechanism vertically transports the books. Because labels need to be applied to the spine, the clamping seat cannot completely hold the book's cover. When the book is thin, the spine is prone to skewing, and the label roller assembly cannot align the gap with the book, leading to labeling failure and poor stability. This solution, however, transports books horizontally. During the labeling process, an edge-aligning device and a book-pressing assembly limit the book's position, keeping the spine fixed and improving labeling stability.

[0041] In step S4, if the book is located at labeling point two, the step also includes pressing the upper part of the label against the upper edge of the cover on the spine.

[0042] Between S3 and S4, there is also a step of grasping the protective film; if the book is located at labeling point one, the middle part of the protective film is pasted onto the label on the plane where the spine is located; if the book is located at labeling point two, the upper part of the protective film is pasted onto the label on the edge of the cover above the spine.

[0043] In step S1, the order of the front and back positions of labeling point one and labeling point two can be interchanged.

[0044] In this embodiment, the thickness of the book can be measured using an image recognition system. A CCD camera captures a photograph of the book spine, and the CCD camera can directly count the number of pixels contained within the pulse width of the image to obtain the object's thickness. Alternatively, a photoelectric diameter gauge can be used. The measured data is fed back to the PLC controller, which is programmed to determine whether to transport the book to labeling point one or labeling point two using a controlled conveyor platform, a second lifting device, and a limit plate.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a spine labeling mechanism based on the above-mentioned spine labeling method includes a conveying platform 2, a robotic arm 5, and a label picking and labeling mechanism 6 mounted on the robotic arm 5; a first labeling roller 7, a second labeling roller 8, and a first driving device 9 are arranged side by side at a labeling position; a gap is left between the first labeling roller 7 and the second labeling roller 8, and the first driving device 9 is used to drive the first labeling roller 7 and the second labeling roller 8 to move horizontally on the cover 4 on the upper and lower sides of the spine 3, respectively;

[0046] At the labeling position, a third labeling roller 10 and a fourth labeling roller 11 are provided, along with a third driving device 12 and a fourth driving device 13 that drive the third labeling roller 10 and the fourth labeling roller 11 to move respectively. The third labeling roller 10 is parallel to the plane where the spine 3 is located, and the fourth labeling roller 11 is perpendicular to the plane where the spine 3 is located. Under the drive of the robotic arm 5, the labeling mechanism 6 affixes the upper part of the label 1 to the edge of the cover 4 on one side of the spine 3. Under the drive of the third driving device 12, the third labeling roller 10 presses the middle part of the label 1 onto the plane where the spine 3 is located. Under the drive of the fourth driving device 13, the fourth labeling roller 11 presses the lower part of the label 1 onto the edge of the cover 4 on the other side of the spine 3.

[0047] In this embodiment, the book is laid flat on the conveying platform 2 for transport. The length of the label 1 is generally greater than the thickness of the book. The back of the label 1 is adhesive and covered with a film. After the label 1 printer prints the ISBN number and other information on the front of the label 1, the film on the label 1 is peeled off by the equipment, and then the label picking and labeling mechanism 6 picks up the front of the label 1.

[0048] Label 1 has a length of L and a book thickness of H. If (LH) / 2 is greater than W, where W ranges from 2mm to 5mm, then the book is conveyed to labeling station 2 via conveyor platform 2. Figure 7As shown, the robotic arm 5 brings the label-taking and labeling mechanism 6 to the labeling location and drives it to affix the upper reverse side of the label 1 to the edge of the cover 4 above the spine 3, i.e., the front of the book near the spine 3. Then, the third drive device 12 drives the third labeling roller 10 to move along a plane parallel to the spine 3. During this movement, the middle of the label 1 is pressed onto the plane of the spine 3. Then, the third drive device 12 drives the third labeling roller 10 to reset. Next, the fourth drive device 13 drives the fourth labeling roller 11 to move along the bottom of the book perpendicular to the plane of the spine 3, pressing the lower reverse side of the label 1 onto the edge of the cover 4 below the spine 3, i.e., the lower part of the book near the spine 3. Finally, the fourth drive device 13 drives the fourth labeling roller 11 to reset, completing the labeling process. The value obtained by (LH) / 2 is the length of the label affixed by the label-taking and labeling mechanism 6 to the edge of the book cover. The robotic arm controls the label-picking and labeling mechanism 6 to pick up the label at a fixed position, meaning the position of the label at the label-picking and labeling mechanism 6 is known. The book spine is affixed to the inner edge of the stop, which is also fixed. The measured book thickness data is fed back to the PLC controller, which is programmed to make a judgment and control the robotic arm to drive the label-picking and labeling mechanism 6 to affix the label to the upper edge of the cover on the spine.

[0049] Label 1 has a length of L and a book thickness of H. If (LH) / 2 is less than W, where W ranges from 2mm to 5mm, then the book is conveyed to labeling station 1 via conveyor platform 2. Figure 8 As shown, the robotic arm 5 brings the label-taking and labeling mechanism 6 to a labeling location and drives the mechanism to affix the center of the reverse side of the label 1 to the plane of the spine 3. Then, the first driving device 9 drives the first labeling roller 7 and the second labeling roller 8 to move along a direction perpendicular to the plane of the spine 3. Using the gap between the first labeling roller 7 and the second labeling roller 8, the top and bottom ends of the reverse side of the label 1 are pressed onto the cover 4 on the top and bottom sides of the spine 3. In this embodiment, W is 2mm.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the conveyor platform 2 is a roller conveyor mechanism. The rollers are rotatably mounted on mounting plates on both sides of the top of the conveyor frame via roller bearings. The rollers are connected at their ends by a synchronous belt drive. A servo motor is connected to the rollers via the synchronous belt drive. Driven by the servo motor, the rollers can rotate, thus achieving the purpose of conveying books. The conveyor platform 2 controls the electrical equipment such as the servo motor, lifting device, and infrared sensor through a controller such as a PLC controller, thereby adjusting the speed and position of the conveyed books. The servo motor model is, but is not limited to, Huichuan 750W. The robotic arm 5 model is, but is not limited to, a CL-Z2304007 multi-axis robotic arm, capable of driving the label-attaching mechanism 6 to move and rotate in multiple dimensions.

[0051] like Figure 5 As shown, the label-taking and labeling mechanism 6 includes a first connecting block 15 connected to the robotic arm 5, a buffer bracket 16 connected to the first connecting block 15, a sliding block 17 on the buffer bracket 16, and a label-absorbing block 18 slidably mounted on the sliding block 17. The label-absorbing block 18 has a label-absorbing cavity inside and an air suction hole 19 at the bottom. The label-absorbing cavity is connected to an air suction pipe through a connector. The air pump device sucks in air to adsorb the label 1 at the air suction hole 19 at the bottom of the label-absorbing block 18. By stopping the air suction, the label 1 can be lowered. After the label-taking and labeling mechanism 6 picks up the label 1, the robotic arm 5 drives the label-absorbing block 18 to press the label 1 onto the spine 3 or the edge of the cover 4 above or below the spine 3, pressing the protective film onto the label 1.

[0052] like Figure 1 , Figure 3 As shown, a stop 20 is provided on one side of the conveying platform 2, and a clearance opening 21 is provided on the stop 20. A clearance platform 22 is provided on the conveying platform 2 at the position corresponding to the clearance opening 21. It also includes a folding device for pushing one side of the spine 3 to the stop 20.

[0053] After the books are aligned by the alignment device, the spine 3 sides of the books are located at the inner edge of the stop 20, with a portion of it located at the clearance opening 21 of the stop 20. The bottom edge of this portion of the book is located at the clearance platform 22 and is suspended in the air. In this embodiment, the stop 20 is a raised baffle, or it can be a baffle that is bolted to the mounting plate. The roller at the clearance platform 22 is shorter than the other rollers, thus forming a space for the clearance platform 22 at the bottom plate of the conveyor frame.

[0054] like Figure 6 As shown, the first labeling roller 7, the second labeling roller 8, the third labeling roller 10, and the fourth labeling roller 11 all include a pressure roller shaft 23, a pressure roller bushing 24 fitted on the outside of the pressure roller shaft 23, and a soft sponge 25 on the outside of the pressure roller bushing 24. The soft sponge 25 has compression deformation characteristics, and the label is squeezed by the soft sponge, which can adapt to the labeling of various thicknesses of book spines.

[0055] The first drive device 9, the third drive device 12, and the fourth drive device 13 can be hydraulic telescopic rods or electric telescopic rods. The telescopic ends of the first drive device 9, the third drive device 12, and the fourth drive device 13 are all equipped with connecting blocks. The first labeling roller 7, the second labeling roller 8, the third labeling roller 10, and the fourth labeling roller 11 are respectively installed on their respective connecting frames. The connecting frames are connected to the corresponding connecting blocks by bolts. The second drive device 26 is a servo motor.

[0056] In this embodiment, the third labeling roller 10 and the third driving device 12 are located above the conveying platform 2, and the third driving device 12 drives the third labeling roller 10 to move up and down; the fourth labeling roller 11 and the fourth driving device 13 are located on one side of the conveying platform 2, and the fourth driving device 13 drives the fourth labeling roller 11 to move horizontally.

[0057] The outer edge of the third labeling roller 10 is positioned such that it can press against the spine 3 located at the inner edge of the stop 20, so that the third labeling roller 10 can press the label 1 onto the surface of the spine 3. The upper edge of the fourth labeling roller 11 is positioned such that it can press against the bottom of the book placed on the top surface of the roller. The fourth labeling roller 11 can enter the clearance table 22 through the clearance hole so that it can extend into the bottom of the book and press the bottom of the reverse side of the label 1 onto the edge of the cover 4 at the bottom of the book.

[0058] like Figure 3 As shown, a telescopic guide plate is also slidably arranged on the fixed bracket 39. The telescopic guide plate is connected to the telescopic rod. The third labeling roller 10 and the third driving device 12 are both installed on the telescopic guide plate. The telescopic guide plate can move horizontally under the drive of the telescopic rod, so that the pressure plate 31 and the third labeling roller 10 can reach the horizontal position at the clearance opening 21, and then move down to press the middle of the label 1 onto the surface where the spine 3 is located.

[0059] like Figure 3 As shown, the edge-returning device includes a stop bar 27, a stop bar bracket 28, a slide rail mounting plate 29, and a second drive device 26. The stop bar 27 is mounted on the stop bar bracket 28, the stop bar bracket 28 is slidably mounted on the slide rail mounting plate 29, and the stop bar bracket 28 is connected to the second drive device 26 in a transmission connection.

[0060] In this embodiment, a lead screw is installed in the middle of the slide rail mounting plate 29, and a guide rod is fixed on the stop rod bracket 28. The other end of the guide rod passes through the guide hole of the lead screw slider and is limited by a nut outside the guide hole. A buffer spring is fitted on the guide rod. Both the stop rod bracket 28 and the lead screw slider are slidably mounted on the slide rail mounting plate 29. The lead screw slider is mounted on the lead screw, and the second drive device 26 is a servo motor. The shaft of the servo motor is connected to the lead screw drive via a synchronous belt. The lead screw structure drives the stop rod bracket 28 and the lead screw slider to move horizontally, thereby driving the stop rod 27 to push the book to the inner edge of the baffle to achieve edge correction. When the spine 3 of the book is located at the inner edge of the stop 20, the guide rod and the buffer spring can play a buffering role to avoid squeezing the book.

[0061] like Figure 3 As shown, a pad 30 of the same height as the conveying surface of the conveying platform 2 is provided at the clearance platform 22 to temporarily support the bottom surface of the book and prevent the spine 3 from bending during the pressing and labeling process.

[0062] A book-pressing assembly for pressing books is provided on the upper part of the conveyor platform 2. It also includes a label-pressing device, which includes a pressure plate 31, a guide rail and a guide rail bracket 32. The pressure plate 31 is connected to the guide rail, and the guide rail bracket 32 ​​is provided with a guide groove that cooperates with the guide rail. A guide rod is movably connected between the pressure plate 31 and the guide rail bracket 32, and a spring is fitted on the guide rod.

[0063] In this embodiment, the third labeling roller 10, the third drive device 12, the book pressing assembly, and the label pressing device are all mounted on a fixed bracket 39 on one side of the conveying platform 2. The book pressing assembly includes a fifth drive device 38 and a horizontal plate 37, used to press down on the book during the labeling process and keep it stable.

[0064] The guide rod can pass through the guide hole on the guide rail bracket 32. The pressure plate 31 is located inside the third labeling roller 10 and maintains the same height so that when the third labeling roller 10 moves downward, the pressure plate 31 can press down on one end of the label 1 that is affixed to the book cover 4 by the labeling mechanism 6. Due to the action of the guide rod, the pressure plate 31 can move upward, so as not to affect the continued downward movement of the third labeling roller 10. When the third labeling roller 10 rises, it resets under the action of the spring. A telescopic guide plate is also slidably arranged on the fixed bracket 39. The telescopic guide plate is connected to the telescopic rod. The third labeling roller 10 and the third drive device 12 are both mounted on the telescopic guide plate. The telescopic guide plate can move horizontally under the drive of the telescopic rod, so that the pressure plate 31 and the third labeling roller 10 can reach the horizontal position at the clearance opening 21. Then the pressure plate 31 and the third labeling roller 10 move downward, pressing down on the upper part of the label 1 and pressing the middle part of the label 1 onto the surface where the spine 3 is located.

[0065] In this embodiment, an anti-interference groove 33 is provided on one side of the horizontal plate 37 to cooperate with the stop bar 27. When the edge-aligning device moves horizontally and pushes the book to the inner edge of the stop bar 20 on one side of the conveyor platform 2, the horizontal plate 37 moves downward under the drive of the fifth drive device 38 and presses against the book cover 4. The anti-interference groove 33 can prevent the horizontal plate 37 from interfering with the stop bar 27 of the edge-aligning device. In this embodiment, the fifth drive device 38 is a pneumatic telescopic rod.

[0066] like Figure 1 , Figure 2 As shown, a first lifting device 34 is provided on one side of the clearance 21, and the first lifting device 34 is connected to the first driving device 9.

[0067] When the label-attaching mechanism 6, driven by the robotic arm 5, affixes the label 1 to the spine 3, to prevent the first drive device 9 from occupying the clearance opening 21, the first drive device 9 can be lowered via the first lifting device 34. After the robotic arm 5 leaves, it is raised again, and the first drive device 9 drives the first labeling roller 7 and the second labeling roller 8 to press the reverse ends of the label 1 onto the cover 4 on both sides of the spine 3. The first lifting device 34 is equipped with a guide plate, which has a sliding groove. The connecting frame of the first drive device 9 is equipped with a sliding rail that matches the sliding rail.

[0068] The conveying platform 2 is also equipped with a limiting plate 35 for limiting the forward direction of the books, and the limiting plate 35 is connected to a second lifting device 36.

[0069] The books are laid flat on the rollers of the conveyor platform 2 for transport. An infrared sensor is installed on the side of the conveyor platform 2. When the books are about to be transported to the clearance opening 21, the second lifting device 36 at the bottom of the roller is activated. The second lifting device 36 drives the limiting plate 35 parallel to the roller to rise from the gap between the rollers, thereby blocking the books from continuing to move forward and stopping the books at the clearance opening 21.
