Description

Technical Field

[0001] The utility model relates to a paper document cleaning structure, and more particularly to a device in which a plurality of roller brushes are installed on an operating table to form a planar displacement path, so that a preset paper document can slide on the table once and complete the cleaning operation of each surface without turning. Background Art

[0002] Most of the book surface cleaning tools currently used are handheld cleaning tools or one-way brushes that are turned over manually. For this reason, relevant industry insiders have developed fully automated cleaning equipment.

[0003] Furthermore, please refer to the previously existing Chinese patent, which filed a utility model patent application for "a book dust remover", application number 201520397106.X, and was announced on November 15, 2015, announcement number CN 204769623U, and please refer to the patent drawings of the prior art, which is a schematic diagram of the prior art structure. As shown in the figure, it can be seen that the prior art is an automatic cleaning device, and the brush wheels inside the device are arranged in a relative and unequal height arrangement form, so that the books are moved in a lateral and upward displacement path when the cleaning operation is performed inside the device. Although it has a cleaning effect, the arrangement of the internal components of the device forms a complex mechanism that is not easy to maintain, so it cannot be popularized in application, and there are many deficiencies and inconveniences, which are the key points that those engaged in this industry are eager to improve.

[0004] Furthermore, the above-mentioned previous case uses two brush wheels that rotate against each other (i.e., full power) to roll the books forward, and the oblique conveyor belt is used as an automatic steering mechanism. The mechanism is complex and easy to damage the books themselves. In particular, the appearance of historical books and paper documents has been slightly damaged due to factors such as age or early production. If they are damaged by the gap caused by the interlaced rolling of the oblique conveyor belt and the straight conveyor belt, it is bound to cause irreparable damage; or, for thinner books and documents (such as files), when leaving the powered brush wheel, the bristles are prone to spraying, or when the books and documents are of different sizes, it is usually necessary to rely on manpower at the entrance to manually adjust the brush wheel position according to the actual width of each book or document, which will seriously affect the progress and efficiency of the cleaning work.

Detailed implementation manners

[0032] To achieve the above - mentioned purposes and effects, the technical means and its structure adopted by the present utility model are described in detail below in conjunction with the drawings with reference to the preferred embodiments of the present utility model to illustrate its features and functions.

[0033] Please refer to Figures 1 to 4 shown in the first - embodiment three - dimensional external view diagram, another - perspective three - dimensional external view diagram, guiding - inclined - surface diagram and top - view diagram of the present utility model respectively. As shown in the figures, the present utility model provides a paper - document cleaning device, which includes a device 1 and a roller - brush set 2, and the connection relationships of each component are as follows:

[0034] A operating table 11 is provided at the top of the device 1. The front - side near - right position of the operating table 11 is the inlet side 12, and the rear - side near - left position of the operating table 11 is the outlet side 13.

[0035] The roller - brush set 2 is assembled on the device 1, and the roller - brush set 2 has several roller brushes 21. However, generally, books and magazines are provided with a book spine. And during the placement of books and magazines, because labels are often attached to the book spine according to requirements, or the book spine is often exposed, it is relatively not easy to be attached by dirt and dust. Therefore, in order to prevent the labels from falling off, in the embodiment of the present utility model, the device 1 of the present utility model is only installed with at least five roller brushes 21 for illustration, but it is not limited thereto.

[0036] The roller brush set 2 has at least five roller brushes 21. In this embodiment, the plurality of roller brushes 21 includes a first roller brush 211 pivotally mounted upright on the operation table 11 adjacent to one side of the inlet side 12, a second roller brush 212 pivotally mounted upright on the operation table 11 on the opposite side of the inlet side, a third roller brush 213 pivotally mounted horizontally longitudinally on the operation table 11, a fourth roller brush 214 pivotally mounted upright on the operation table 11 opposite to the first roller brush 211, and a fifth roller brush 215 pivotally mounted horizontally transversely above the operation table 11 adjacent to one side of the outlet side 13. As shown in the attached drawings, the plurality of roller brushes 21 can be respectively buried inside the device 1 according to actual needs and can be adjusted respectively by an adjustment module, so as to adjust the height of the plurality of roller brushes 21 on the operation table 11 and appropriately expose part of the bristles facing the surface of the operation table 11, for example, between about 1 to 5 centimeters (cm) or other exposed areas of bristles, so that a displacement path 110 is formed on the operation table 11 from the inlet side 12 along the installation position of the plurality of roller brushes 21 to the outlet side 13. In this preferred embodiment, the displacement path 110 at least includes a first path 110a formed from the inlet side 12 through the first roller brush 211 to the second roller brush 212, a second path 110b formed from the second roller brush 212 through the third roller brush 213 to near the fourth roller brush 214, and a third path 110c formed from the fourth roller brush 214 through the fifth roller brush 215 to the outlet side 13, which are connected together.

[0037] As described above, the operation table 11 also has a guide inclined surface 14 extending in the direction of the outlet side 13, and the guide inclined surface 14 is provided in the displacement path 110.

[0038] Furthermore, the aforementioned guide inclined surface 14 is provided on the operation table 11 below the fifth roller brush 215 and extends in the direction of the outlet side 13 to form a state communicating with the outside. However, it includes but is not limited to the position or the setting method of the aforementioned guide inclined surface 14 on the operation table 11. That is, the aforementioned guide inclined surface 14 can also be provided at other places on the operation table 11 that do not correspond to below the fifth roller brush 215, or the aforementioned guide inclined surface 14 can also be pivotally connected to the operation table 11 by one side of a plate body 141, and the other side is in a movable state and can be appropriately pressed down to make the plate body 141 in an inclined shape to serve as the guide inclined surface 14 (for example Figure 7 、 Figure 8A shown and its disclosure and description). Moreover, the installation method of the plurality of roller brushes 21 assembled on the operation table 11 is not the focus of the present invention, so it will not be elaborated in detail here.

[0039] Please refer to Figure 5 、 Figure 6 Cooperate with Figures 1 - 4As shown, in actual application, the present invention is to first place the preset paper document 3 flatly on the entrance side 12 of the operating table 11 of the device 1, and then manually push along the first path 110a of the displacement path 110 and the right side of the preset paper document 3 (as shown in the figure) to brush the first roller brush 211, move forward to the second path 110b and move along the second path 110b to the left plane, and at the same time, the front side of the preset paper document 3 (as shown in the figure) is brushed by the second roller brush 212, and then the bottom side of the preset paper document 3 (as shown in the figure) is brushed by the second roller brush 212. ) passes through (or brushes over) the third roller brush 213, and then continues to slide to the left to the fourth roller brush 214 (and the guide ramp 14), continues to move forward along the third path 110c and the left side of the preset paper document 3 (as shown in the figure) brushes the fourth roller brush 214, continues to move forward at the guide ramp 14, and makes the preset paper document 3 slide to the exit side 13 through the guide ramp 14 by the preset paper document 3's own weight or the operator's appropriate pushing force, and at the same time, the top side of the preset paper document 3 (as shown in the figure) brushes the fifth roller brush 215. In the process of the one-time displacement of the preset paper document 3, each surface (i.e., each side) of the preset paper document 3 is aligned and touches the bristles of the plurality of roller brushes 21 exposed outside the operation table 11 during the displacement, so that each surface of the preset paper document 3 can use the bristles of the plurality of roller brushes 21 to remove dirt or dust on the surface, so as to achieve a cleaning effect on the surface of the preset paper document 3. That is, in this embodiment, the installation positions of the second roller brush 212 and the fifth roller brush 215 are staggered, so that the preset paper document 3 can form a smooth displacement action along the displacement path 110 in the figure.

[0040] It should be noted that the right side, front side, bottom side, left side and top side of the aforementioned preset paper document 3 are not limited and can be determined according to the placement position when placed by the operator.

[0041] See also Figure 7 , Figure 8A and Figure 8B As shown, the second embodiment of the utility model is different from the first embodiment described above. Figure 3 The difference is that the guide inclined surface 14 below the fifth roller brush 215 is a plate 141, one side of the plate 141 is provided with a pivoting portion 142 that can be pivotally assembled to the through hole of the operating table 11, and an active joint side 143 is formed on the other side of the plate 141, and a damping member (not shown) and one end of an elastic element 144 connected to the inside of the device 1 can be installed at the bottom of the joint side 143, and the damping member is protruding from the plate 141, including but not limited to. When the preset paper document 3 moves along the displacement path 110 to the plate 141 (such as Figures 4 - 6As shown in the figure, by presetting the weight of the paper document 3 itself and pushing and pressing it manually, a downward pressure will be generated on the preset paper document 3, which will press down the plate body 141. As a result, the elastic element 144 below the engaging side 143 will be elastically compressed, enabling the plate body 141 to drive the engaging side 143 to deflect downward in an inclined shape through the pivot of the pivoting portion 142. At this time, the preset paper document 3 has a guiding inclined surface 14 on the inclined plate body 141 and is connected to the external state of the outlet side 13 (such as Figure 8A As shown in the figure), and then, by using the weight of the preset paper document 3 itself and the downward pressing force of a person, it slides to the outlet side 13. At the same time, during the sliding process, the upper surface of the preset paper document 3 can be brought into contact with the bristles of the fifth roller brush 215 to achieve a cleaning effect (such as Figure 8B As shown in the figure). And after the preset paper document 3 passes through the inclined plate body 141 (guiding inclined surface 14) and leaves the device 1 from the outlet side 13, the elastic element 144 can push the plate body 141 back to its original position by using its own elastic reaction force. At the same time, the damping member can control the plate body 141 to return to the same horizontal table surface as the operation table surface 11. The elastic element 144 can be any one of components and mechanisms with elastic deformation or buffer deformation, such as a spring or a hydraulic buffer damping mechanism, or a pneumatic buffer damping mechanism, or a limiter. Furthermore, the foregoing elastic element 144 can also be arranged in other connection ways as long as it can provide the elastic action for the plate body 141 to be pressed down and pushed back to its original position.

[0042] Please refer to Figure 9 As shown in the figure, it is another schematic diagram of the operation table surface of the third embodiment of the present invention. As shown in the attached drawing, the difference between the third embodiment and the first embodiment of the present invention is that the installation positions of the second roller brush 212 and the fifth roller brush 215 in the third embodiment are flush-mounted. In this way, it can be seen from the figure that although the distance of the displacement path 110 will be extended, it does not affect the cleaning operation and efficacy, but can make the operation table surface 11 suitable for a working environment with a smaller placement space.

[0043] Please refer to Figure 4 、 Figure 10As shown, it is a top-plan schematic diagram of the present utility model and a planar schematic diagram of the split and offset operation tabletop of the fourth embodiment. As shown in the attached drawings, the difference between the fourth embodiment and the first embodiment of the present utility model lies in that in the fourth embodiment, the operation tabletop 11 is designed in a split and offset manner and is composed of a first operation tabletop 111 and a second operation tabletop 112. The plurality of roller brushes 21 are respectively and appropriately arranged on the first and second operation tabletops 111 and 112. For example, the first roller brush 211, the second roller brush 212, and the third roller brush 213 of the roller brush 21 are arranged on the first operation tabletop 111, and the fourth roller brush 214 and the fifth roller brush 215 of the roller brush 21 are arranged on the second operation tabletop 112, so that a two-stage first displacement path 1101 is formed on the first operation tabletop 111 of the displacement path 110, and a two-stage second displacement path 1102 is formed on the second operation tabletop 112. This split design enables the device 1 to have the utilities of being easy to carry, assemble, store, or repair, etc.

[0044] The paper document cleaning structure of the present utility model further includes a dust collection module 4, and the dust collection module 4 is arranged inside Figures 1 to 10 the device 1 shown in the figure. In order not to affect the installation positions of other components in the figure, it is only shown as an example in Figure 4 , Figure 5 , Figure 6 . As shown in the attached drawings, the dust collection module 4 includes a negative pressure dust collection assembly 41, a plurality of suction heads 42 correspondingly arranged beside "each" roller brush 21, and pipelines 43 respectively connecting the plurality of suction heads 42 and the dust collection assembly 41. Taking the second roller brush 212 shown in the figure as an example, when the second roller brush 212 is in the cleaning operation, dirt and dust will adhere to the bristles. The dirt and dust on the bristles can be transported along the pipeline 43 through the dust collection assembly 41 by the suction head 42 of the dust collection module 4 using the negative pressure of suction, and the dirt and dust are discharged or removed outward, thereby enhancing the cleaning effect of the plurality of roller brushes 21. Among them, the suction head 42 can also be designed in the form of a vibration unit to remove the dirt and dust on the bristles. However, the structural form and assembly method of the dust collection module 4 or the vibration unit can be achieved by general techniques, so they will not be elaborated here.

[0045] In addition, a power source (such as a motor, etc.) can also be installed inside the device 1, and the power source can be respectively connected to the plurality of roller brushes 21, so that the plurality of roller brushes 21 can be actuated by the power source to form a rotating state during actual application, thereby enhancing the cleaning effect on the surface of the preset paper document 3. And the power source can also be connected to the dust collection assembly 41 or the suction head 42 of the above-mentioned dust collection module 4, thereby forming a start linkage between the plurality of roller brushes 21 and the dust collection module 4. However, the connection and assembly method between the plurality of roller brushes 21 and the power source can be achieved by general techniques, so they will not be elaborated here.

[0046] In addition, during the long-term cleaning of the device 1, dirt, dust, etc. that cannot be removed may accumulate on the bristles of the plurality of roller brushes 21. At this time, the plurality of roller brushes 21 on the operation table 11 can be replaced. Moreover, the length, shape, or softness of the bristles on the plurality of roller brushes 21 can be customized according to actual needs and design requirements. The present utility model is not limited thereto.

[0047] In addition, in the embodiment of the present utility model, the displacement path 110 on the operation table 11 is the moving path of the preset paper document 3 formed by the arrangement positions of the plurality of roller brushes 21. However, the plurality of roller brushes 21 can also be adjusted to different installation positions. And when the inlet side 12 and the outlet side 13 are on the same side, the displacement path 110 can also be formed into a U-shaped moving path, so that each surface of the preset paper document 3 can be touched by the plurality of roller brushes 21 to achieve a cleaning effect.

[0048] In addition, in the second embodiment of the present utility model, the plate body 141 swings by means of pivot connection and elastic compression, so that the thickness of the preset paper document 3 can abut against the bristles of the fifth roller brush 215 to achieve a cleaning effect. However, in order to conform to the thicknesses of various books, magazines, paper documents, boxed paper, etc., the fifth roller brush 215 can also be set in an elastic design form of moving up and down. It only needs to make the preset paper document 3 abut against the bristles of the fifth roller brush. Such simple modifications and equivalent structural changes should all be included in the patent scope of the present utility model by the same token, and are hereby stated.

[0049] Therefore, the main focus of the present utility model is on the operation table 11 of the device 1 having a displacement path formed along the arrangement positions of the plurality of roller brushes 21. And when a guide slope 14 is appropriately provided in the displacement path 110 to facilitate the passage of the preset paper document 3, one of the roller brushes 21 opposite to the guide slope 14 can be used to contact and clean the top surface (or bottom surface) of the preset paper document 3, enabling the preset paper document 3 to perform cleaning operations on each surface along the displacement path 110, which is the key point of protection.

[0050] Therefore, when the present utility model is actually applied, it can have the following advantages:

[0051] 1. As described in the prior art, when books and the like are placed in the conventional device, the cleaning path in the device is provided with a power transmission device due to the setting of the brush wheel in the device, resulting in relatively complex internal components of the device, especially the inclined conveyor belt 4 in the prior art is easy to interfere with the forward books deviating from the preset path, hindering the book conveyance, and even easily scratching the books. The present invention is a table-type displacement path 110, which simplifies the settings of many conveying devices (such as belts), steering devices (such as steering wheels, connecting rods), etc., which can not only reduce the probability of equipment failure and greatly improve work efficiency, but also effectively save assembly time and reduce the number of components used, thereby achieving the utility of simple assembly, convenient mass production and lower cost.

[0052] 2. The preset paper document 3 described in the present invention can be books, magazines, data files or boxed paper books of different thickness and binding sizes. The same table design of the displacement path 110 on the operating table of the present invention can allow various books, periodicals, documents, etc. to slide on the operating table 11 and be cleaned by the roller brush group on their outer surface, so as to improve the adaptability of the device 1 of the present invention. Furthermore, the device 1 of the present invention is only equipped with at least five roller brushes 21 in the embodiment of the present invention for implementation, which includes but is not limited to this.

[0053] 3. The use environment of the present invention can be a library with a large collection of books and periodicals. The table-top design of the displacement path 110 of the present invention can reduce the moving distance of the preset paper document 3, thereby forming an effect of convenient operation, which can relatively achieve a fast operation to achieve a fast cleaning effect, thereby saving a large amount of time spent on the cleaning process of books.

[0054] 4. In addition to the basic cleaning and dust removal functions, the plurality of roller brushes 21 of the present invention also have a forward power auxiliary kinetic energy; for example, Figure 4 As shown, each roller brush 21 has different installation patterns and rotation directions (as shown in the arrow direction in the figure) according to the position on the operating table 11 and the displacement path 110. In this way, the utility model can fully cooperate with the different thicknesses of the preset paper documents 3, or the preset paper documents 3 of different thicknesses can be interspersed for cleaning work. Even the multiple roller brushes 21 can drive the preset paper documents 3 to move forward in the displacement operation direction, reducing the force applied by personnel. For example, the friction area at the third roller brush 213 and the fifth roller brush 215 is particularly large, and the forward power assisted by the operator is relatively more obvious, which provides auxiliary forward kinetic energy similar to a conveyor belt while cleaning.

[0055] V. The present utility model has a displacement path 110 formed on the operation table surface 11 along the positions of each roller brush 21, for the preset paper document 3 to perform a one-time table surface sliding and complete the cleaning operation of each surface thereof without turning. This design allows the operator to manually push forward or translate the preset paper document 3 within the range formed on the operation table surface 11 of the device 1. For example Figures 4 - 6 the forward push of the first path 110a and the third path 110c in [example] is extremely labor-saving. For example Figures 4 - 6 when the second path 110b is horizontally moved in [example], the third roller brush 213 assists in rolling, which helps to save the force exerted by the operator during translation. Accordingly, the present utility model can effectively solve the disadvantages and problems caused by the conventional prior art of transporting books forward by a power brush wheel.

[0056] The above detailed description is only for the preferred feasible embodiments of the present utility model, but this embodiment is not used to limit the patent protection scope of the present utility model. Any other equivalent changes and modifications completed without departing from the technical spirit disclosed by the present utility model should still fall within the patent coverage scope of the present utility model.
