Detailed Description
For a better understanding and explanation of the present invention, reference will now be made in detail to the present invention as illustrated in the accompanying drawings. The present invention is not limited to these specific embodiments only. Rather, modifications and equivalents of the invention are intended to be included within the scope of the claims.
It should be noted that numerous specific details are set forth in the following detailed description. It will be understood by those skilled in the art that the present invention may be practiced without these specific details. In the following detailed description of various embodiments, structures and components well known in the art are not described in detail in order to not unnecessarily obscure the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a delivery device according to the present invention, in the embodiment, the delivery device includes a paper storage portion 10, a paper pushing portion 20, a paper twisting portion 30, and a paper delivery portion 40, wherein:
as shown in fig. 1, the paper storage portion 10 includes a paper storage box 11 composed of a plurality of paper storage cavities 12 adjacently arranged in a predetermined direction, the paper storage cavities 12 having openings 13, each of the paper storage cavities storing at least one page of paper document 14. As will be understood by those skilled in the art, since different paper documents 14 are stored in different paper storage cavities 12, all the paper documents 14 in the paper storage box 11 are spatially separated and arranged in the order of the positions of the paper storage cavities 12.
Since an important function of the delivery device provided by the present invention is to realize the automatic delivery step of the sequenced multiple paper documents, the paper storage box 11 essentially temporarily stores the multiple paper documents at a predetermined position to maintain the spatial isolation state and the sequential arrangement state among the multiple paper documents, so as to achieve the pre-sequencing state of the multiple paper documents.
In most application scenarios, the document stack formed by the multiple paper documents is in a disorder arrangement state before being sorted, but the paper collecting device provided by the invention can be used in cooperation with a mechanical paper feeding device, and a series of steps such as paper taking and feeding are carried out by taking one paper document 14 as a minimum processing unit, so that the paper document 14 finally enters the paper storage cavity 12. Specifically, the paper documents 14 are conveyed into the paper storage cavity 12 through the opening 13 by the mechanical paper feeder, and in the process, the paper storage box 11 may be driven by the power device to perform spatial position conversion according to the control signal, so that the plurality of different openings 13 included in the paper storage box 11 are respectively aligned with the paper outlet of the mechanical paper feeder, so that different paper documents 14 enter different paper storage cavities 12. This process is not shown in fig. 1, nor is the present invention limited to the specific construction of the mechanical paper feeder. It will be understood by those skilled in the art that all of the paper documents 14 stored in the paper storage box 11 are in the pre-ordered state of the ordered arrangement, and the cooperative operation of the paper storage portion 10, the paper pushing portion 20, the paper twisting portion 30 and the paper delivery portion 40 is to complete the paper delivery step of all of the paper documents 14 stored in the paper storage box 11 according to the order property of the paper documents according to the arrangement order of the paper storage cavities 12, which will be explained in detail later.
With continued reference to fig. 1, the paper pushing portion 20 is configured to push the end portion 141 of the paper document 14 out of the paper storage cavity 12 through the opening 13, and to make the end portion 141 stay outside the paper storage cavity 12. The paper pushing portion 20 may be implemented by any suitable mechanism, and may include a movable member extending into the storage chamber 12 or a roller member disposed within the storage chamber 12, the movable member or roller member being configured to contact the paper documents 14 in the storage chamber 12 directly, and provide sufficient kinetic energy to the paper documents 14 by contact to move the paper documents 14 out of the storage chamber 12 through the opening 13. In the embodiment shown in fig. 1, the paper pushing portion 20 includes at least one paper pushing rod 21 and a second driving motor 22, wherein the paper pushing rod 21 is disposed in a matching limiting through slot (not shown in fig. 1) on the housing of the paper storage cavity 12 and extends through the paper storage box 11. The second driving motor 22 is configured to drive the paper pushing rod 21 to move along the limiting through slot towards the direction of the opening 13 until reaching a set position, and then stop, so as to push the paper document 14, push the end portion 141 out of the paper storage cavity 12 through the opening 13, and stop the end portion 141 outside the paper storage cavity 12. Typically, the mode of driving the paper pushing rod 21 by the second driving motor 22 can be implemented by using a mechanical driving structure as shown in fig. 1, that is, the paper pushing rod 21 is fixed to the movable member 24, and a screw 23 threadedly engaged with the movable member 24 extends from a rotating shaft of the second driving motor 22, so that the second driving motor 22 drives the screw 23 to rotate to drive the movable member 24 to move along the screw 23, and finally drives the paper pushing rod 21 to move laterally in the direction of the opening 13 (i.e., in the direction B shown in fig. 1). The paper pushing rod 21 stops after moving to the set position, so as to meet the requirement that the end portion 141 stays outside the paper storage cavity 12 after the paper document 14 is pushed out, and meet the requirement that the paper document 14 cannot easily slide out of the paper storage cavity 12 due to self gravity to cause paper taking failure, therefore, the maximum moving stroke of the paper pushing rod 21 needs to be controlled by determining the set position, and preferably, the maximum moving stroke is selected to ensure that the area of the paper document 14 carried by the paper storage cavity 12 is at least 50% of the area of the paper document 14. The braking of the paper pushing rod 21 can be realized by controlling the second driving motor 22, so that the second driving motor 22 can be realized by selectively using a stepping motor or a servo motor, and in other embodiments, the braking of the paper pushing rod 21 can be realized by limiting the limiting through groove by reasonably setting the size of the limiting through groove, so that the paper pushing rod 21 reaches the maximum movement stroke when moving close to the edge of the limiting through groove, and the paper pushing rod 21 stops moving due to the limitation of the edge of the limiting through groove. The present invention is not particularly limited as to how to stop the paper pushing bar 21 after moving to the set position.
To further explain the process of pushing the paper document 14 out of the paper storage cavity 12 by the paper pushing rod 21 in the paper pushing portion 20, referring to fig. 2, fig. 2 is a structural schematic diagram after the state change of the embodiment shown in fig. 1, and referring to fig. 1, the paper pushing rod 21 moves along the direction B shown in fig. 1, and finally reaches the setting position shown in fig. 2 from the initial position shown in fig. 1. In the state shown in fig. 2, all the paper documents 14 in the paper storage box 11 are pushed by the paper pushing rod 21 to move, so that a part of the plurality of paper documents 14 is exposed out of the paper storage cavity 12, and particularly, the end portion 141 of the paper document 14 stays out of the paper storage cavity 12.
In the state shown in fig. 2, it will be understood by those skilled in the art that different paper documents 14 and their ends 141 are respectively in different spatial positions, and the next step is to take out these paper documents 14, which are respectively in different spatial positions, from the paper storage box 11 completely in order. Therefore, further, only by making the relative displacement between the paper storage box 11 and the paper pickup part 30, the paper documents 14 at different positions of the paper storage box 11 can sequentially contact the paper pickup part 30. The relative displacement may be generated by driving the paper stacking box 11 to displace from the initial position relative to the paper rolling portion 30 by a power source, or by driving the paper rolling portion 30 to displace from the initial position relative to the paper stacking box 11 by a power source. Preferably, in the present embodiment, the paper storage box 11 is configured to perform a unidirectional linear motion along the predetermined direction, so that the plurality of end portions 141 sequentially contact the paper twisting portion 30, respectively, the paper twisting portion 30 is further configured to drive the end portions 141 to move the paper documents 14 outwards from the paper storage cavity 12 and into the paper receiving portion 40, and the paper receiving portion 40 is used for carrying a document stack formed by a plurality of paper documents 14 sequentially entering the paper receiving portion 40.
Specifically, it has been described above that the plurality of paper storage cavities 12 included in the paper storage box 11 are arranged adjacently in the predetermined direction, and therefore, the paper storage box 11 is configured to perform the unidirectional linear motion in the predetermined direction, so that the order in which the ends of the paper documents 14 in the paper storage box 11 contact the paper rolling portion 30 is the same as the order in which the plurality of paper storage cavities 12 in the paper storage box 11 are arranged, so as to ensure that the paper fetching sequence of the plurality of paper documents 14 in the paper storage box 11 still follows the pre-ordering sequence thereof in the paper storage box 11 during the paper collection process. The predetermined direction is the direction a shown in fig. 1 or fig. 2, and is preferably a direction perpendicular to the horizontal plane, and accordingly, the plurality of paper storage cavities 12 constituting the paper storage box 11 are also arranged adjacently in the direction perpendicular to the horizontal plane, which has the advantage that the paper documents 14 can stay in the paper storage cavities 12 by virtue of their own weight, and if the predetermined direction is not the direction perpendicular to the horizontal plane, the paper documents 14 may be displaced by their own weight, which may result in an additional limit structure being added in the paper storage cavities 12. Therefore, selecting the predetermined direction as a direction perpendicular to the horizontal plane can help simplify the internal structure of the paper storage chamber 12.
Typically, the manner of driving the paper storage box 11 to perform the unidirectional linear motion can be implemented by using a mechanical conveying structure shown in fig. 1 and 2, wherein a plurality of paper storage cavities 12 are arranged in parallel and adjacently along the predetermined direction, the paper storage portion 10 further includes a first driving motor 16 and a screw 18, the screw 18 is arranged in parallel with the predetermined direction, a movable member 17 threadedly engaged with the screw 18 is sleeved on the screw 18, the movable member 17 is fixedly connected with the paper storage box 11, and the first driving motor 16 is configured to drive the screw 18 to rotate so as to drive the movable member 17 to drive the paper storage box 11 to move along the screw 18 to implement the unidirectional linear motion. The purpose of the unidirectional linear movement of the paper storage box 11 is to enable the ends 141 of the paper documents 14 respectively located at different spatial positions to sequentially contact the paper rolling portion 30, so that the paper rolling portion 30 can sequentially take out the multiple paper documents 14 in the paper storage box 11 from the paper storage cavity 12. In this regard, as will be understood by those skilled in the art, the moving speed of the paper storage box 11 cannot be too fast, and if the moving speed of the paper storage box 11 is too fast, the contact time between the end 141 and the paper rubbing portion 30 may be too short, so that the driving force is lost when the paper document 14 is not completely taken out from the paper storage cavity 12, and the paper taking failure may be caused. Thus, the first drive motor 16 desirably has a settable rate characteristic, and typically the first drive motor 16 may be implemented using a servo motor or a stepper motor, preferably the first drive motor 46 being a servo motor. The servo motor can achieve high control precision, and the control precision of the movement rate of the paper storage box 11 can be adaptively adjusted according to the factors such as the weight and the size of the paper document 14 through the adaptive adjustment with the screw 18, so that the optimal paper discharging effect can be obtained.
To further illustrate the movement process of the paper storage box 11, please refer to fig. 3, fig. 3 is a schematic structural view after the state of the embodiment shown in fig. 1 is further changed, and in conjunction with fig. 2, the movable member 17 is driven by the rotation of the screw 18 to drive the paper storage box 11 to perform a unidirectional linear movement along the direction a shown in fig. 2 from the initial position shown in fig. 2, and after a period of movement, the paper storage box 11 reaches the position shown in fig. 3. During the movement of the paper storage case 11, the end 141 of the paper document 14 staying outside the paper storage chamber 12 sequentially contacts the paper pickup portion 30, causing the paper document to move from inside the paper storage chamber 12 to outside into the paper collection portion 40. As shown in fig. 2 or 3, since the movement locus of the paper storage box 11 is a unidirectional linear movement in the direction a, the paper documents 14 at the lowest position of the paper storage box 11 contact the paper rolling part 30 first, and then as shown in fig. 3, the paper documents 14 at the lower position of the paper storage box 11 contact the paper rolling part 30 respectively.
Specifically, the paper twisting unit 30 is used for taking out different paper documents 14 from the corresponding paper storage cavities 12, and typically, the paper twisting unit 30 includes at least one paper twisting wheel, and the rotation speed of the paper twisting wheel is configured to match the speed of the unidirectional linear motion, so that the paper twisting wheel sequentially drives the end portions 141 respectively during the unidirectional linear motion of the paper storage box 11. The rotation speed of the pickup roller is configured to match the speed of the unidirectional linear motion, that is, the rotation speed of the pickup roller should be selected to be able to transmit enough kinetic energy to the paper documents 14 during the motion of the paper storage box 11 to completely separate the paper documents 14 from the paper storage cavity 12, and not to cause the too high kinetic energy to cause the too fast outlet speed of the paper documents 14 to unstably fall into the paper receiving portion 40, and cause the paper receiving failure. In other embodiments, the paper rubbing section 30 may be implemented by a paper rubbing roller.
With further reference to fig. 4, fig. 4 is a schematic structural view of the embodiment shown in fig. 1 after further change of state, and with reference to fig. 3, the paper storage box 11 continues to perform unidirectional linear motion in the direction a to the position shown in fig. 4, where the topmost part of the paper storage box is already close to the paper rolling portion 30, and the paper documents 14 in the last paper storage cavity 12 of the paper storage box 11 contact the paper rolling portion 30 and are ready to be driven by the paper rolling portion 30 to fall into the paper receiving portion 40. It will be understood by those skilled in the art that after the paper storage box 11 moves from the initial position shown in fig. 1 to the final position shown in fig. 4, all the paper documents 14 in the paper storage box 11 are taken out by the paper feeding unit in the same order as the arrangement order of the paper storage cavities 12 in the paper storage box 11, that is, the multiple pre-ordered paper documents 14 in the paper storage box 11 fall into the paper receiving unit 40 in the order of the document stack 140, and the paper receiving process is finished. The delivery speed depends on the following factors: the moving speed of the paper storage box 11 and the paper taking effect of the matching of the paper twisting part 30 and the moving track of the paper storage box 11, therefore, the paper delivery device provided by the invention has a fast processing time, and after the two factors are adjusted, all the paper documents 14 in the paper storage box 11 can be delivered in a short time. The paper feeding path of the paper is simple, the risks of paper jam and paper rolling are avoided, and the whole paper collecting device is easy to maintain.
In a preferred embodiment, the number of the paper storage cavities 12 included in the paper storage portion 10 is 10 to 200, the paper storage cavities 12 are arranged adjacently in parallel to form the paper storage box 11, accordingly, the number of the paper storage cavities 12 determines an upper limit of the number of paper documents that can be sorted by the paper delivery device of the present invention, for example, when the number of the paper storage cavities 12 is 100, at least 100 paper documents can be automatically delivered. Since the paper storage box 11 needs to move linearly in one direction, the reasonable reduction of the overall size of the paper storage box 11 helps to reduce the movement space occupied by the delivery device. In addition, the paper storage cavity 12 should have a certain rigidity, so as to support the paper documents 14 contained therein, and maintain small deformation due to factors such as inertia resistance of the movement of the paper storage box 11, so as to avoid damaging the paper documents 14 contained therein, or avoid paper collection failure caused by the paper documents 14 sliding out of the paper storage cavity 12 due to excessive deformation. In view of the above, in the present embodiment, the housing of the paper storage chamber 12 is made of a rigid material or a flexible material that is tightened by stress, the thickness of the housing is 0.1mm to 5mm, and the distance between the upper and lower housings of the paper storage chamber 12 is 1mm to 10 mm. Based on the above parameters, even if the thickness of the housing is selected to be the maximum and the distance between the upper and lower housings of the paper storage chamber 12 is selected to be the maximum, when the number of the paper storage chambers 12 is 100, the height of the paper storage box 11 formed by the paper storage chambers 12 is only 10mm x 100+5mm x 101-1.55 m, and the maximum movement stroke of the paper storage box 11 is less than or equal to the height of the paper storage box 11. This is advantageous for increasing the integration of the delivery device provided by the present invention and for reducing the footprint of the delivery device, facilitating its use in common indoor office environments, preferably since the movement of the sheet storage box 11 is perpendicular to the horizontal plane, the office in a typical building can provide a vertical height for its normal operation. The term "tensed by stress" means that an external stress is applied to the flexible material, and the flexible material has sufficient rigidity due to the stress-stiffening effect, so that the characteristics of the paper storage chamber 12 made of the flexible material can meet the bearing requirements and deformation limiting requirements of the paper storage chamber 12. In view of reducing the load on the first drive motor 16, it is possible to use a rigid material that is as lightweight as possible for the paper storage chamber 12, and it is preferable to use, for example, a fiber reinforced plastic as the material for forming the housing of the paper storage chamber 12.
Referring to fig. 1 to 4, when the pickup portion 30 contacts the paper document 14 and further drops it into the paper receiving portion 40, it is considered that the paper document 14 can naturally drop into the paper receiving portion 40 by using the self-weight of the paper document 14. Therefore, the paper receiving portion 40 is preferably disposed below the paper pickup portion 30.
Referring to fig. 5, fig. 5 is a schematic perspective view of an embodiment of a delivery device according to the present invention, similar to the delivery device shown in fig. 1 to 4, the delivery device shown in fig. 5 includes several main components, namely, a paper storage portion 10, a paper pushing portion 20, a paper twisting portion 30, and a paper delivery portion 40, wherein the paper storage portion 10 still includes a paper storage box 11 formed by a plurality of paper storage cavities for accommodating multiple paper documents; the paper pushing part 20 comprises two paper pushing rods as shown in fig. 5, and the two paper pushing rods extend through the limiting through grooves arranged at the top of the paper storage box 11 and penetrate through the paper storage box 11; the paper twisting part 30 is composed of a plurality of paper twisting wheels which rotate coaxially; the paper receiving portion 40 is implemented by a case without a cover. Even though fig. 5 illustrates a specific structure of some components, the functions and operation principles of various parts of the delivery device shown in fig. 5 are the same as those described in the foregoing for the same or similar components, and thus are not described in detail. The schematic perspective structure is provided only to facilitate better understanding of the structure of the delivery device provided by the present invention for those skilled in the art.
In conjunction with fig. 1 to 4, it is further considered that since the paper itself has a characteristic of being easily deformed, when the paper document 14 enters the paper receiving portion 40, there is a possibility that the paper receiving process may be inefficient due to a phenomenon such as curling or bending caused by the deformation. Therefore, the present invention has modified the specific form of the paper receiving portion 40 in some ways after taking this phenomenon into full consideration. Referring to fig. 6, fig. 6 is a schematic structural diagram of a paper receiving portion shown in any one of fig. 1 to 5, in which the paper receiving portion 40 includes a paper receiving box 41, and a paper guiding structure is disposed on at least one inner vertical surface of the paper receiving box 41.
In the preferred embodiment shown in fig. 6, a leading structure of a set of paper guide blocks 43 is provided at the inner end of the delivery box 41, wherein each paper guide block 43 comprises a plurality of inverted teeth uniformly arranged in a straight line. When the paper document falls into the paper receiving box 41, the paper edge of the paper document can contact the inverted teeth, and the situation that the paper bounces upwards under the action of the inverted teeth can be prevented, so that the situation that the paper document curls in the paper receiving box 41 to influence the smooth entering of subsequent paper is avoided. When the bottom surface of the paper receiving box 41 forms a certain included angle with the ground, experiments prove that paper can more easily and smoothly enter the paper receiving box 41. Therefore, in an embodiment, it is considered that the paper receiving box 41 is inclined at an angle with respect to the horizontal plane, but this is not favorable for the stable fixing of the paper receiving box 41 itself, and for this, the specific method adopted in the preferred embodiment shown in fig. 6 is to arrange the paper receiving box 41 parallel to the horizontal plane, and at the same time, arrange the bottom surface 44 of the paper receiving box 41 for bearing the document stack at an angle with respect to the horizontal plane, and the angle is in the range of 0 degree to 10 degrees.
In view of facilitating the operator to take out the document stack in the paper receiving box 41, a notch 45 is formed in the bottom surface of the paper receiving box 41, and the operator can access a portion of the bottom surface of the document stack exposed through the notch 45 and easily apply a lifting force to the portion of the bottom surface to take out the document stack from the paper receiving box 41.
In addition, in order to reduce the messy degree of paper caused by unequal kinetic energy when the paper documents enter the paper receiving box 41, the internal size of the paper receiving box 41 can be reasonably set, and the problem of large left-right displacement difference between different layers of paper after the paper documents sequentially enter the paper receiving box 41 to form a stack is solved as much as possible by means of the limiting effect of the side wall of the paper receiving box 41. It is therefore conceivable to set the paper receiving tray 41 so as to increase in width in the direction toward the paper pickup portion 30 shown in fig. 1 to 4, and to set the minimum width of the paper receiving tray 41 to a value range greater than or equal to the width of the paper document. Referring to fig. 6, the width X1 of the proximal end of the paper receiving box 41 is greater than the width X2 of the distal end thereof, and taking the paper document as international standard paper a4 as an example, the value of X2 may be considered to be 5mm to 20mm greater than the width of a4 paper, so that the problem of messy paper during paper receiving can be minimized.
Referring to fig. 7, fig. 7 is a cross-sectional view of the delivery portion shown in fig. 6, in consideration of a paper feeding rate, the number of the inverted teeth included in the paper guide block ranges from 10 to 30, and preferably the number of the inverted teeth is 20; the inclination angle of the inverted tooth ranges from 20 degrees to 40 degrees, and preferably, the inclination angle of the inverted tooth is 30 degrees; the inter-tooth distance between each group of adjacent inverted teeth ranges from 2mm to 10mm, and preferably, the inter-tooth distance is 5 mm. The selection of the numerical values can improve the paper finishing degree in the paper collecting process and reduce the risk of paper rolling.
The control signals for controlling the paper storage box and the paper pushing rod can be generated by embedded devices which are integrated with the paper collecting device provided by the invention.
