Technical Field

[0001] The invention relates to the technical field of book collection and editing, and in particular to a spine labeling method and a spine labeling mechanism. Background Art

[0002] In libraries or bookstores, in order to facilitate the identification and classification of different books, labels are often attached to the spines of books and then scanned into the library. Label information generally includes book title, author, publisher, ISBN number, etc. This information can help readers better understand and choose books, and it is also convenient for libraries, bookstores and other institutions with a large number of books to manage and index books. Retrieving label information can help managers quickly find and obtain the required book information.

[0003] At present, except for a small number of books that require manual labeling, the labeling of books in large libraries mostly adopts mechanical operations. For example, the Chinese patent with patent number CN202220708165.4 discloses a book labeling mechanism and labeling system for an intelligent three-dimensional library, which includes a labeling robot, a label picking and labeling component, and a label rolling component. The patent first completes the conventional labeling action through the label picking and labeling component, that is, the label grabbing and applying actions are completed by the labeling robot. There are two situations for the labels applied to the spine by the label picking and labeling component. One is that the spine is thick enough and the labels are all applied on the spine surface. The other is that the spine is thin and the labels protrude from the spine surface. The scheme also provides a label rolling component, which bends the label through the label rolling component so that the labels protruding from the spine are applied to the book on both sides of the spine.

[0004] The structure of the labeling roller in the patent solution is fixed, and the labeling gap cannot match different book thicknesses, resulting in a limited scope of application. Therefore, it is necessary to further improve the above labeling mechanism. Summary of the invention

[0006] A spine labeling method comprises the following steps:

[0007] S1: The label length is known to be L, and the book thickness H is measured. If (LH) / 2 is less than W, and the range of W is 2mm-5mm, the book is transported to labeling station 1 through the conveying platform. Otherwise, the book is transported to labeling station 2 through the conveying platform.

[0008] S2: Perform edge trimming on the books and push the spine of the books to the inner edge of the conveying platform;

[0009] S3: Grab the label; if the book is at labeling position 1, stick the middle of the label on the plane where the spine is located; if the book is at labeling position 2, stick the upper part of the label on the edge of the cover above the spine;

[0010] S4: If the book is at labeling position 1, stick the upper and lower ends of the label on the cover above and below the spine respectively; if the book is at labeling position 2, first stick the middle of the label on the plane where the spine is located, and then stick the lower end of the label on the edge of the cover below the spine.

[0011] Furthermore, between steps S2 and S3, a book pressing step for fixing the position of the book is also included.

[0012] Furthermore, in step S4, if the book is located at labeling location 2, a label pressing step is also included in which the upper portion of the label is pressed against the upper edge of the cover of the book spine.

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

[0014] Furthermore, in step S1, the front and rear positions of the first labeling location and the second labeling location may be swapped.

[0034] The spine labeling method and spine labeling mechanism of the present invention are further described below in conjunction with embodiments.

[0035] A spine labeling method comprises the following steps:

[0036] S1: The label length is known to be L, and the book thickness H is measured. If (LH) / 2 is less than W, and the range of W is 2mm-5mm, the book is transported to labeling station 1 through the conveying platform. Otherwise, the book is transported to labeling station 2 through the conveying platform.

[0037] S2: Perform edge trimming on the books and push the spine of the books to the inner edge of the conveying platform;

[0038] S3: Grab the label; if the book is at labeling position 1, stick the middle of the label on the plane where the spine is located; if the book is at labeling position 2, stick the upper part of the label on the edge of the cover above the spine;

[0039] S4: If the book is at labeling position 1, stick the upper and lower ends of the label on the cover above and below the spine respectively; if the book is at labeling position 2, first stick the middle of the label on the plane where the spine is located, and then stick the lower end of the label on the edge of the cover below the spine.

[0040] Between steps S2 and S3, a book pressing step for fixing the position of the book is also included. The Chinese patent with the prior art patent number CN202220708165.4 is a book labeling mechanism and labeling system for an intelligent three-dimensional library. The feeding mechanism in this scheme includes a clamping seat for clamping the book and a feeding drive module for driving the clamping seat to move horizontally. The mechanism transports the book vertically. Since the label needs to be affixed to the spine, the clamping seat cannot completely clamp the cover of the book. When the book is thin, the spine of the book is prone to deflection, and the label rolling assembly cannot align the gap with the book, resulting in labeling failure and poor stability. In this scheme, the books are transported horizontally, and the books are limited by the edge return device and the book pressing assembly during the labeling process, so that the spine can remain fixed, thereby improving the stability of labeling.

[0041] In step S4, if the book is at labeling location 2, a label pressing step is also included in which the upper portion of the label is pressed against the upper edge of the cover of the book spine.

[0042] The step of grabbing the protective film is also included between S3 and S4; if the book is located at labeling position 1, the middle part of the protective film is pasted on the label on the plane where the spine is located; if the book is located at labeling position 2, the upper part of the protective film is pasted on the label on the edge of the cover above the spine.

[0043] In step S1, the front and rear positions of labeling location 1 and labeling location 2 may be swapped.

[0044] In this embodiment, the method of measuring the thickness of the book can adopt an image recognition system, and a CCD camera can be used to take a picture of the book spine. The CCD camera can directly count the number of pixels contained in the pulse width of the pattern to obtain the thickness of the object. A photoelectric diameter gauge can also be used. The measured data is fed back to the PLC controller, and the controller is programmed to judge and control the conveying platform to convey, the second lifting device and the limit plate to lift and limit, so as to convey the book to the first labeling place or the second labeling place.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a spine labeling mechanism based on the above-mentioned spine 3 labeling method includes a conveying platform 2, a mechanical arm 5, and a label taking and labeling mechanism 6 arranged on the mechanical arm 5; a first labeling roller 7, a second labeling roller 8 and a first driving device 9 are arranged side by side in an upper and lower direction at a position of the labeling place; 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] A third labeling roller 10, a fourth labeling roller 11, and a third driving device 12 and a fourth driving device 13 for driving the third labeling roller 10 and the fourth labeling roller 11 to move are provided at the second labeling position; wherein 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; the label taking and labeling mechanism 6, driven by the mechanical arm 5, sticks the upper part of the label 1 on the edge of the cover 4 on one side of the spine 3, the third labeling roller 10, driven by the third driving device 12, presses the middle part of the label 1 on the plane where the spine 3 is located, and the fourth labeling roller 11, driven by the fourth driving device 13, presses the lower part of the label 1 on the edge of the cover 4 on the other side of the spine 3.

[0047] In this embodiment, the book is placed flat on the conveying platform 2 for transportation. The length of the label 1 is generally greater than the thickness of the book. The reverse side of the label 1 is sticky and coated. After the ISBN number and other information are printed on the front side of the label 1 by the label printer, the coating on the label 1 is peeled off by the device, and then the label removal and labeling mechanism 6 absorbs the front side of the label 1.

[0048] The length of label 1 is L, the thickness of the book is H, if (LH) / 2 is greater than W, and the range of W is 2mm-5mm, the book will be transported to labeling station 2 through the conveying platform 2; Figure 7As shown, the robot arm 5 brings the label picking and labeling mechanism 6 to the second labeling location, and drives the label picking and labeling mechanism 6 to stick the upper part of the reverse side of the label 1 on the edge of the cover 4 at the upper part of the spine 3, that is, the front of the book near the spine 3, and then the third driving device 12 drives the third labeling roller 10 to move along the direction parallel to the plane where the spine 3 is located. During the movement, the middle part of the label 1 can be pressed on the plane where the spine 3 is located, and then the third driving device 12 drives the third labeling roller 10 to reset; then the fourth driving device 13 drives the fourth labeling roller 11 to move along the bottom of the book perpendicular to the plane where the spine 3 is located, and presses the lower part of the reverse side of the label 1 on the edge of the cover 4 at the lower part of the spine 3, that is, the lower part of the book near the spine 3, and finally the fourth driving device 13 drives the fourth labeling roller 11 to reset, completing the labeling process. Among them, the value obtained by (LH) / 2 is the length of the label stuck by the label picking and labeling mechanism 6 on 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, that is, the position of the label at the label picking and labeling mechanism 6 is known, and the spine of the book is attached to the inner edge of the baffle, 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 attach the label to the cover edge above the spine.

[0049] The length of label 1 is L, the thickness of book is H, if (LH) / 2 is less than W, W range is 2mm-5mm, then the book is transported to labeling place 1 through conveying platform 2; Figure 8 As shown, the robot arm 5 brings the label picking and labeling mechanism 6 to a labeling location, and drives the label picking and labeling mechanism 6 to stick the middle of the reverse side of the label 1 on the plane where the spine 3 is located, and then the first driving device 9 drives the first labeling roller 7 and the second labeling roller 8 to move along the direction perpendicular to the plane where the spine 3 is located, and uses the gap between the first labeling roller 7 and the second labeling roller 8 to press the upper and lower ends of the reverse side of the label 1 onto the cover 4 on the upper and lower sides of the spine 3. In this embodiment, W is 2 mm.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, the conveying platform 2 is a roller conveying mechanism, and the roller is rotatably mounted on the mounting plates on both sides of the top of the conveying frame through roller bearings. The rollers are connected at the ends through synchronous belt transmission, and the servo motor is connected to the roller through the synchronous belt transmission. Under the drive of the servo motor, the roller can rotate, thereby achieving the purpose of conveying books. The conveying platform 2 controls the servo motor, lifting device, infrared sensor and other electrical equipment through a controller such as a PLC controller, thereby adjusting the speed and position of conveying books. The model of the servo motor is but not limited to Huichuan 750w. The model of the mechanical arm 5 is but not limited to CL-Z2304007 multi-axis mechanical arm, which can drive the labeling mechanism 6 to move and rotate in multiple dimensions.

[0051] like Figure 5 As shown, the label picking and labeling mechanism 6 includes a first connecting block 15 connected to the mechanical arm 5, a buffer bracket 16 connected to the first connecting block 15, a sliding block 17 is provided on the buffer bracket 16, a label suction block 18 is slidably mounted on the sliding block 17, a label suction cavity is provided in the label suction block 18, an air suction hole 19 is provided at the bottom, and the label suction cavity is connected to the air suction pipe through a joint. The air pump device absorbs the label 1 at the air suction hole 19 at the bottom of the label suction block 18 by suction, and the label 1 can be put down by stopping the suction. After the label picking and labeling mechanism 6 absorbs the label 1, the mechanical arm 5 drives the label suction block 18 to press the label 1 on the spine 3 or the edge of the cover 4 above and below the spine 3, and press the protective film on the label 1.

[0052] like Figure 1 , Figure 3 As shown, a stopper 20 is provided on one side of the conveying platform 2, and an escape opening 21 is provided on the stopper 20. The conveying platform 2 is provided with an escape platform 22 at a position corresponding to the escape opening 21; it also includes a edging device for pushing one side of the spine 3 to the stopper 20.

[0053] After the book is trimmed by the trimming device, the spine 3 side of the book is located at the inner edge of the stopper 20, a part of which is located at the escape opening 21 of the stopper 20, and the bottom edge of the book of this part is located at the escape platform 22 and is suspended in the air. In this embodiment, the stopper 20 is a raised baffle, and can also be a baffle installed on the mounting plate by bolts. The roller at the escape platform 22 is shorter than other rollers, so that a space for the escape platform 22 is formed 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 sleeved 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 a compression deformation characteristic and relies on the soft sponge to squeeze the label to adapt to spine labeling of various thicknesses.

[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 correspondingly 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 preferably positioned to be able to press the book spine 3 located at the inner edge of the stopper 20, so that the third labeling roller 10 can press the label 1 onto the surface where the book spine 3 is located. The upper edge of the fourth labeling roller 11 is preferably positioned to be able to press the bottom of the book placed on the top surface of the roller, and the fourth labeling roller 11 can enter the avoidance platform 22 from the avoidance hole so as to 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 is also slidably provided on the fixed bracket 39, the telescopic guide is connected to the telescopic rod, the third labeling roller 10 and the third driving device 12 are both installed on the telescopic guide, and the telescopic guide can move horizontally under the drive of the telescopic rod, so that the pressing plate 31 and the third labeling roller 10 can reach the horizontal position at the avoidance opening 21, and then move downward to press the middle part of the label 1 onto the surface where the spine 3 is located.

[0059] like Figure 3 As shown, the edging device includes a baffle rod 27, a baffle rod bracket 28, a slide rail mounting plate 29 and a second driving device 26. The baffle rod 27 is mounted on the baffle rod bracket 28, the baffle rod bracket 28 is slidably mounted on the slide rail mounting plate 29, and the baffle rod bracket 28 is transmission-connected to the second driving device 26.

[0060] In this embodiment, a screw rod is installed in the middle of the slide rail mounting plate 29, and a guide rod is fixed on the baffle rod bracket 28. The other end of the guide rod passes through the guide hole of the screw rod slider and is limited by a nut on the outside of the guide hole. A buffer spring is mounted on the guide rod. The baffle rod bracket 28 and the screw rod slider are both slidably mounted on the slide rail mounting plate 29. The screw rod slider is mounted on the screw rod, and the second driving device 26 is a servo motor. The rotating shaft of the servo motor is connected to the screw rod through a synchronous belt. The baffle rod bracket 28 and the screw rod slider are driven horizontally by the screw rod structure, thereby driving the baffle rod 27 to push the book to the inner edge of the baffle to achieve edge processing. When the spine 3 of the book is located at the inner edge of the baffle 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 having the same height as the conveying surface of the conveying platform 2 is provided at the avoidance platform 22 for temporarily supporting the bottom surface of the book to prevent the book spine 3 from bending during the process of pressing and labeling.

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

[0063] In this embodiment, the third labeling roller 10, the third driving device 12, the book pressing assembly and the label pressing device are all installed on a fixed bracket 39 on one side of the conveying platform 2. Among them, the book pressing assembly includes a fifth driving device 38 and a horizontal plate 37, which are used to press the books during the labeling process to keep the books stable and motionless.

[0064] The guide rod can pass through the guide hole on the guide rail bracket 32. The pressing 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 pressing plate 31 can press one end of the label 1 attached to the book cover 4 by the label removal and labeling mechanism 6, and due to the action of the guide rod, the pressing plate 31 can move upward, so as not to affect the continued downward movement of the third labeling roller 10, and when the third labeling roller 10 rises, it is reset under the action of the spring. A telescopic guide plate is also slidably arranged on the fixed bracket 39, and 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 pressing plate 31 and the third labeling roller 10 can reach the horizontal position at the avoidance opening 21, and then the pressing plate 31 and the third labeling roller 10 move downward, respectively press the upper part of the label 1, and press 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 cooperating with the stopper 27 is provided on one side of the horizontal plate 37. When the edge-binding device moves horizontally to push the book to the inner edge of the stopper 20 on one side of the conveying platform 2, the horizontal plate 37 moves downward under the drive of the fifth driving device 38 and presses on the book cover 4. The anti-interference groove 33 can prevent the horizontal plate 37 from interfering with the stopper 27 of the edge-binding device. In this embodiment, the fifth driving 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 avoidance opening 21 , and the first lifting device 34 is connected to the first driving device 9 .

[0067] When the label taking and labeling mechanism 6 is driven by the mechanical arm 5 to attach the label 1 to the book spine 3, in order to prevent the first driving device 9 from occupying the position of the avoidance opening 21, the first driving device 9 can be lowered by the first lifting device 34, and then raised again after the mechanical arm 5 leaves, and the first driving device 9 drives the first labeling roller 7 and the second labeling roller 8 to press the two ends of the reverse side of the label 1 onto the cover 4 on both sides of the book spine 3. A guide plate is installed on the first lifting device 34, and a slide groove is provided on the guide plate, and a slide rail matching the slide rail is provided on the connecting frame of the first driving device 9.

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

[0069] The books are placed flat on the rollers of the conveying platform 2 for conveyance. An infrared sensing device is installed on the side of the conveying platform 2. When the books are about to be conveyed to the avoidance opening 21, the second lifting device 36 at the bottom of the roller is started, and the second lifting device 36 drives the limit plate 35 parallel to the roller to rise from the gap between the rollers, thereby blocking the books from continuing to move forward and making the books stay at the avoidance opening 21.
