Description

Technical Field

[0001] The invention relates to the technical field of release paper stripping equipment, and in particular to a double-sided release paper stripping device for an RFID tag of an intelligent three-dimensional book library. Background Art

[0002] Book acquisition and editing refers to the work of library editors to collect and edit book materials according to the nature and tasks of the library, and to classify and record the books in accordance with the catalog regulations. In traditional book acquisition and editing, editors are required to manually classify books according to their attributes, that is, editors obtain the attributes of books according to the title of the book, and then classify them. Although this method can realize the acquisition and editing of books, it requires a lot of manpower costs and has low work efficiency. At the same time, since the number of books in the library is usually very large, and the process of borrowing and returning books is also very cumbersome and prone to errors, in order to manage books more conveniently and efficiently, it is necessary to manually classify the pages or covers of the books during the book acquisition and editing process. The RFID tags are printed with collection codes, affixed with RFID tags or stamped with other labels to facilitate the management of books; however, the pasting of RFID tags in the prior art is a major technical problem. Since RFID tags are pasted on a continuous strip-shaped release paper substrate (lower release paper tape) at equal intervals, and each RFID tag is pasted with a release paper strip (upper release paper) covering it, the release papers on both sides of the RFID tag must be torn off before use, and then the RFID tag is pasted on the book page. However, there is no such equipment in the prior art that can automatically complete the peeling of the release papers on both sides of the RFID tag, which is a key factor restricting the automation of book collection and editing; therefore, a reliable solution to the above problem is urgently needed.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0034] Reference Figure 1-Figure 11 As shown, an embodiment of a double-sided release paper peeling device for an RFID tag of an intelligent three-dimensional book library of the present invention;

[0035] A double-sided release paper peeling device for an RFID tag of an intelligent three-dimensional book library, comprising:

[0036] A roller assembly, the roller assembly comprising an unwinding roller 24, a rewinding roller 31 and a plurality of guide rollers 34, the release paper tape 11 with the RFID tag 13 attached thereto is tensionedly connected between the unwinding roller 24 and the rewinding roller 31, and the release paper tape 11 unwound between the unwinding roller 24 and the rewinding roller 31 is wound around the plurality of guide rollers 34 according to a preset path;

[0037] A pre-opening component, the pre-opening component is arranged on the path of the release paper tape 11, and the pre-opening component is used to tear off part of the upper release paper 12 covering the RFID tag 13 from the release paper tape 11;

[0038] A tearing mechanism, the tearing mechanism is used to tear the upper release paper 12 off the release paper tape 11 and partially grab it, and completely tear the upper release paper 12 off the release paper tape 11;

[0039] A label peeling component includes a label carrier 20, one side of the label carrier 20 is provided with a pressing piece for changing the movement path of the release paper tape 11, a gap is provided between the pressing piece and the label carrier 20 for the release paper tape 11 to pass through, and driven by the winding roller 31, the release paper tape 11 moves in the gap between the pressing piece and the label carrier 20, and the RFID label 13 with the upper layer of release paper 12 torn off is peeled off the release paper tape 11 and enters the label carrier 20.

[0040] The present invention also includes a base 14 and a vertical plate 15 fixed on the base 14, the unwinding roller 24, the winding roller 31 and the plurality of guide rollers 34 are arranged parallel to each other and are rotatably mounted on the vertical plate 15, the new material roll is clamped and mounted on the unwinding roller 24, the free end of the release paper tape 11 passes around the plurality of guide rollers 34 and the auxiliary roller 18 according to a preset path and passes through the gap between the support plate 16 and the label carrier 20, and finally is wound on the winding roller 31, as shown in FIG. Figure 3 As shown, the arrow in the figure indicates the movement direction of the release paper tape 11. At the same time, a first photoelectric sensor 46 for detecting whether the release paper tape 11 is separated from the unwinding roller 24 is also installed on the vertical plate 15. Specifically, when the release paper tape 11 is used up or other unexpected circumstances cause the release paper tape 11 to be separated from the unwinding roller 24, the first photoelectric sensor 46 will send out an alarm signal.

[0041] In one embodiment of the present invention, referring to Figure 1-Figure 4 As shown, the unwinding roller 24 is rotatably mounted on the bearing seat 25, and both ends of the unwinding roller 24 extend out of the bearing seat 25, and the bearing seat 25 is fixed on the vertical plate 15, and both ends of the unwinding roller 24 are respectively provided with a clamping block and a damping mechanism, and the clamping block and the damping mechanism are respectively located on both sides of the vertical plate 15, and the clamping block includes a fixed clamping block 26 coaxially fixed on the unwinding roller 24 and an adjusting clamping block 27 connected to the unwinding roller 24 by threads, and the fixed clamping block 26 is located between the vertical plate 15 and the adjusting clamping block 27, and the adjusting clamping block 27 can be removed from the unwinding roller 24, and the fully rolled release paper tape 11 is sleeved on the unwinding roller 24, and then the adjusting clamping block 27 is screwed on the end of the unwinding roller 24, so that the core of the fully rolled release paper tape 11 is clamped between the adjusting clamping block 27 and the fixed clamping block 26.

[0042] The damping mechanism includes a spring 29, an adjustment seat 28 and a support seat 30. The support seat 30 is sleeved on the outside of the unwinding roller 24 and the support seat 30 rotates freely. The adjustment seat 28 is coaxially connected to the unwinding roller 24 through a thread. The adjustment seat 28 can adjust the axial position on its unwinding roller 24, and then can adjust the pressing force of the spring 29, so as to adjust the resistance of the unwinding roller 24 to rotation. The support seat 30 is located between the adjustment seat 28 and the vertical plate 15. The spring 29 is sleeved on the outside of the unwinding roller 24 and the two ends of the spring 29 are respectively abutted on the adjustment seat 28 and the support seat 30, and the support seat 30 is abutted on the bearing seat 25. Due to the setting of the damping mechanism, the resistance of the unwinding roller 24 during the forced rotation and unwinding process is relatively large, so that the unfolded release paper tape 11 can be forced to be tensioned, which is convenient for the peeling of the RFID tag 13.

[0043] In one embodiment of the present invention, referring to Figure 1-Figure 4 As shown, one end of the winding roller 31 is connected to a driving mechanism for driving it to rotate, and the driving mechanism includes a driving motor 32 and a synchronous belt 33. One end of the winding roller 31 is connected to the output shaft of the driving motor 32 through the synchronous belt 33 to form a belt drive. The driving motor 32 is fixed on the vertical plate 15. The driving motor 32 drives the winding roller 31 to rotate through the synchronous belt 33, and then the release paper tape 11 can be driven forward by the winding roller 31. At the same time, the winding roller 31 can roll up the blank release paper tape 11. Of course, there are many types of driving mechanisms for driving the winding roller 31 to rotate, such as the motor directly drives the winding roller 31 to rotate through the reducer, and the electric drive drives the winding roller 31 to rotate through the chain. At the same time, a second photoelectric sensor 47 for detecting whether the release paper tape 11 is separated from the winding roller 31 is also installed on the vertical plate 15. Specifically, when the release paper tape 11 is separated from the winding roller 31 due to an accident, the second photoelectric sensor 47 will send an alarm signal.

[0044] In one embodiment of the present invention, referring to Figure 1-Figure 3 As shown, the top pressure member is a support plate 16 fixed on the vertical plate 15, and the inner side of the support plate 16 is provided with a boss 17 for laterally positioning the release paper tape 11, that is, the release paper tape 11 moves between the boss 17 and the special-shaped block 36, and the setting of the boss 17 ensures that the release paper tape 11 will not easily escape from the slit 37 of the special-shaped block 36. The label carrier 20 is fixed to the vertical plate 15 through the first bracket 19. The label carrier 20 is arranged at the end of the support plate 16 and a gap is provided between the two for the release paper tape 11 to pass through. Figure 3After the release paper tape 11 passes through the gap between the support plate 16 and the label carrier 20, the edge of the support plate 16 abuts against the inner side of the release paper tape 11, so that the movement direction and movement trajectory of the release paper tape 11 change by at least 90 degrees, and the RFID tag 13 on the release paper tape 11 cannot continue to move with the release paper tape 11. Therefore, as the release paper tape 11 moves, the RFID tag 13 above it is forced to peel off the release paper tape 11, and the RFID tag 13 immediately enters the label carrier 20 after being peeled off. Figure 6 As shown, the label carrier 20 is provided with a plurality of support portions 21 distributed in a straight line at equal intervals, and the upper surfaces of the plurality of support portions 21 are all on the same plane, and the plane is used to carry the peeled RFID label 13; when the RFID label 13 enters the support plane formed by the plurality of support portions 21, as shown in FIG. Fig.10 As shown, since the multiple support parts 21 form a hollow support structure, the contact area between the RFID tag 13 and the label carrier 20 can be reduced. Since the lower surface of the RFID tag 13 is sticky, this hollow support structure can reduce the adhesion between the RFID tag 13 and the label carrier 20, making it easier for the robot to grab the RFID tag 13.

[0045] In one embodiment of the present invention, referring to Figure 1-Figure 3 As shown, an auxiliary roller 18 parallel to the guide roller 34 is rotatably installed below the support plate 16, and the auxiliary roller 18 is used to support the release paper tape 11 passing through the gap between the support plate 16 and the label carrier 20. A first metal sensor 23 for detecting the RFID tag 13 is also provided above the support plate 16. The first metal sensor 23 and the second metal sensor 40 are used in conjunction with each other to control the movement of the release paper tape 11 and prevent discontinuities such as missing RFID tags 13. The first metal sensor 23 is fixed to the vertical plate 15 by a second bracket 22, and the release paper tape 11 passes between the support plate 16 and the first metal sensor 23.

[0046] In one embodiment of the present invention, referring to Figure 1-Figure 3 and Figure 5-Figure 9As shown, the pre-opening assembly includes a pressing block 35 and a special-shaped block 36 both mounted on the upper surface of the support plate 16. The end surface of the pressing block 35 is a plane for pressing the edge of the release paper tape 11. The edge of the release paper tape 11 is bent downward by the pressing block 35, and the end of the upper release paper 12 above the RFID tag 13 is tilted as much as possible to prepare for the slit 37 passing through the pressing block 35. The pressing block 35 is arranged on the feeding side of the special-shaped block 36. The special-shaped block 36 is provided with a slit 37 for the edge of the release paper tape 11 to pass through. The slit 37 is away from the release paper tape 11. The direction of the RFID tag 13 above the paper tape 11 is tilted downward, and a blade corner 38 for scraping off the upper layer of release paper 12 above the RFID tag 13 is provided above the slit 37, and a guide bevel 39 smoothly connected to the blade corner 38 is provided above the special-shaped block 36. The setting of the guide bevel 39 enables the upper layer of release paper 12 scraped up by the blade corner 38 to enter the top of the special-shaped block 36 more smoothly, and a second metal sensor 40 for detecting the RFID tag 13 is installed below the support plate 16, and the second metal sensor 40 is located on the discharge side of the special-shaped block 36. The edge of the release paper tape 11 is forced to bend downward by the inclined slits 37 on the special-shaped block 36. As the release paper tape 11 moves, the blade corners 38 on the special-shaped block 36 will scoop up the end of the upper release paper 12, so that the corresponding end portion of the upper release paper 12 is located above the special-shaped block 36, and the release paper tape 11 passes through the slits 37 of the special-shaped block 36, thereby achieving partial separation of the upper release paper 12 from the release paper tape 11, achieving pre-opening of the upper release paper 12, and preparing for completely tearing off the upper release paper 12.

[0047] In one embodiment of the present invention, referring to Figure 1-Figure 3 and Fig.11 As shown, the tearing mechanism is arranged above the support plate 16, and the tearing mechanism includes a tearing cylinder 41, a pressing cylinder 44 and a connecting block 42. The cylinder body of the tearing cylinder 41 is obliquely fixed on the vertical plate 15, and the connecting block 42 is fixed on the piston rod of the tearing cylinder 41. The lower part of the connecting block 42 is provided with a receiving portion 43 formed by bending. The cylinder body of the pressing cylinder 44 is fixed on the connecting block 42, and a pressing block 45 is fixed on the piston rod of the pressing cylinder 44. The pressing block 45 and the upper surface of the receiving portion 43 are used to cooperate with clamping the portion of the upper layer of release paper 12 to be torn off the release paper tape 11. When the upper layer of release paper 12 is opened, the tearing cylinder 41 drives the connecting block 42 to extend obliquely downward, so that the upper surface of the receiving portion 43 on the connecting block 42 is flush with or lower than the upper surface of the special-shaped block 36, as shown in FIG. Figure 6 As shown, the release paper tape 11 then continues to move forward, that is, press Figure 6When the second metal sensor 40 detects the RFID tag 13, the release paper tape 11 stops moving. At this time, the end of the upper release paper 12 above the shaped block 36 that has completed the pre-opening enters the upper part of the receiving portion 43. Figure 7 As shown, the clamping cylinder 44 then drives the clamping block 45 to move downward to clamp the end of the upper release paper 12 on the receiving portion 43, and finally the tearing cylinder 41 drives the connecting block 42 to retract obliquely upward, and the upper release paper 12 clamped on the connecting block 42 is completely torn off the release paper tape 11, and the tearing of the upper release paper 12 is completed.

[0048] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
