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 paper pushing mechanism according to the present invention, the paper pushing mechanism includes a temporary storage portion 10, at least one push rod 20, a first push rod driving portion 30 and a second push rod driving portion 40, wherein:
the temporary storage part 10 comprises a plurality of temporary storage cavities 11, each temporary storage cavity 11 is used for storing one or more paper documents, a limiting through groove 12 is formed in a shell of each temporary storage cavity 11, and a push rod 20 is arranged in the limiting through groove 12 and extends to and penetrates through the temporary storage cavity 11. Specifically, the size of the limiting through groove 12 is slightly larger than the diameter of the push rod 20, so that the push rod 20 can move along the extending direction of the limiting through groove 12, and the part of the push rod 20 extending inside the temporary storage cavity 11 can contact and push the paper documents stored in the temporary storage cavity 11; also, when the buffer chamber 11 needs to move up and down along the push rod, the limit penetration groove 12 does not limit the up and down movement of the buffer chamber 11 due to collision with the push rod 20. In the present embodiment, the temporary storage section 10 includes a plurality of temporary storage cavities 11 arranged adjacently and in parallel in a direction perpendicular to the horizontal plane, and the plurality of temporary storage cavities 11 have identical or substantially identical external dimensions to collectively form the temporary storage section 10 having a cubic shape. Typically, the temporary storage cavity 11 should have a certain rigidity, so as to support the paper documents contained therein, and maintain a small deformation against factors such as inertia when the temporary storage portion 10 moves, so as to avoid damaging the paper documents contained therein, or avoid a paper delivery failure caused by the paper documents sliding out of the temporary storage cavity 11 due to an excessive deformation. In view of the above, in the present embodiment, the housing of the buffer chamber 11 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 buffer chamber 11 is 1mm to 10 mm. The term "tensioned by stress" as used herein means that an external stress is applied to the flexible material, which has sufficient rigidity due to the stress-stiffening effect, so that the characteristics of the buffer chamber 11 made of the flexible material can also meet the load-bearing requirements and the deformation-limiting requirements of the buffer chamber 11 as described above. It should be noted that the paper document stored in the temporary storage chamber 11 may enter the temporary storage chamber 11 through a paper feeding path implemented by using a suitable mechanical structure, and the present invention does not limit the specific implementation of the paper feeding path. Due to the different spatial positions of the plurality of temporary storage chambers 11, the plurality of paper documents stored in the plurality of temporary storage chambers 11 have the fact of being arranged in sequence according to the arrangement sequence of the plurality of temporary storage chambers 11. It will be understood by those skilled in the art that the driving rod 20 is moved for the purpose of pushing out the paper document stored in the buffer chamber 11 from the buffer chamber 11.
In the embodiment shown in fig. 1, it is preferable that the paper pushing mechanism includes two pushing rods 20, and the two pushing rods 20 are arranged in parallel, so that the stress point of the paper document pushed in the temporary storage cavity 11 can be further increased, which helps to improve the stability of the paper document pushed and prevent the edge of the paper document from being damaged. Correspondingly, due to the increase of the number of the push rods 20, the temporary storage cavity 11 should also be provided with a corresponding limiting through groove. In other embodiments, the number of push rods 20 may be implemented as more than two. It should be noted that although fig. 1 does not show the limit through-groove at the bottom of the temporary storage section 10, it can be understood by those skilled in the art that since the push rod 20 penetrates the entire temporary storage section 10, the temporary storage chamber 11 at the lowest position of the temporary storage section 10 is also provided with a limit through-groove matching with the push rod 20.
In order to drive the push rod 20, the present embodiment provides that the first and second push rod driving parts 30 and 40 drive the push rod 20. Specifically, one end of the push rod 20 is connected to the first push rod driving part 30 through a first connecting piece 32, and the other end of the push rod 20 is connected to the second push rod driving part 40 through a second connecting piece 42, and the push rod 20 performs angular rotation around the first connecting piece 32 and/or the second connecting piece 42. As shown in fig. 1, when the push rod 20 needs to be driven to move, the first push rod driving portion 30 drives the first connecting member 32 to move, so as to drive one end of the push rod 20 to move therewith, and simultaneously, the second push rod driving portion 40 drives the second connecting member 42 to move in the same direction relative to the first connecting member 32, so as to drive the other end of the push rod to perform the same-direction movement. Because both ends of the push rod 20 are driven, the push rod 20 moves along the limiting penetrating groove 12, and correspondingly, the part of the push rod 20, which is arranged in the temporary storage cavity 11, moves along with the temporary storage cavity 11, so that the aim of pushing out the paper documents in the temporary storage cavity 11 is fulfilled. In a preferred embodiment, the maximum stroke of the pusher 20 may be set to be adjustable by setting the operating parameters of the first and second pusher driving parts 30 and 40, thereby controlling the length of the paper document pushed out of the buffer chamber 11 and exposed outside the buffer chamber 11.
The plurality of buffer chambers 11 in this embodiment are arranged adjacently and in parallel in a direction perpendicular to the horizontal plane, and for this example, since the two ends of the push rod 20 can respectively rotate angularly around the connecting members (the first connecting member 32 and the second connecting member 42) connected thereto, if the speeds of the first connecting member 32 and the second connecting member 42 moving in the same direction are set to be different, the moving strokes of the two ends of the push rod 20 in the same time are different, the angle of the push rod 20 with respect to the direction perpendicular to the horizontal can be changed, whereby the maximum stroke reached by the push rod 20 in the respective buffer chamber 11 is also different, this makes it possible to vary the length of the plurality of paper documents ejected from the buffer chamber 11, which are exposed outside the buffer chamber 11, and also to vary the timing of the ejection of the plurality of paper documents ejected from the buffer chamber 11. Therefore, by configuring the angle of the push rod 20, the flexible configuration of the length, the push time and the sequence of pushing out multiple paper documents from the temporary storage cavity 11 can be realized, which can meet the specific conditions of different paper pushing scenes.
Specifically, in order to set the speeds of the first connecting element 32 and the second connecting element 42 in the same direction to be different, the first connecting element 32 and the second connecting element 42 may use the same power source to drive gear sets with different transmission ratios to realize different speeds of movement, or may use different power sources to drive the movement respectively. In the embodiment shown in fig. 1, it is contemplated that different power sources may be used to drive the first link 32 and the second link 42. As shown in fig. 1, the first push rod driving part 30 includes a first driving motor 31 and a timing belt matched with a rotation shaft of the first driving motor 31, the timing belt drives the first connecting member 32, and similarly, the second push rod driving part 40 includes a second driving motor 41 and a timing belt matched with a rotation shaft of the second driving motor 41, the timing belt drives the second connecting member 42. It will be appreciated by those skilled in the art that due to the timing belt, the movement rate and movement stroke of the first link 32 are related to the first drive motor 31, and the movement rate and movement stroke of the second link 42 are related to the second drive motor 41, and preferably, the first drive motor 31 and the second drive motor 41 are configured to have different rotation rates, and in combination with the characteristic that the opposite angular rotation of the two ends of the pusher 20 can occur, the flexible configuration of the length, the pushing time and the sequence of pushing out the multiple paper documents from the buffer 11 as described above can be realized. The first driving motor 31 and the second driving motor 41 may be implemented with servo motors or stepping motors in consideration of precision control. Preferably, the paper pushing mechanism further comprises a motor control module (not shown in fig. 1) for controlling the rotation rate and the rotation stroke of the first driving motor 31 and the second driving motor 41. It will be understood by those skilled in the art that the motor control module may include a servo controller or a stepper motor controller that is compatible with the first drive motor 31 and the second drive motor 41.
In order to achieve the above-mentioned feature that the push rod 20 rotates around the first connecting element 32, a preferred structure is provided in the present embodiment, which is described with reference to fig. 1 and 2, fig. 2 is a partially enlarged structural view of the portion a shown in fig. 1, and as shown in fig. 2, the first connecting element 32 includes a linear bearing 33 and a deep groove ball bearing 34, wherein the linear bearing 33 is sleeved on the push rod 20, and one end of the push rod 20 extends and is exposed outside the linear bearing 33, so that the push rod 20 can slide freely in the linear bearing 33, and it is satisfied that when the relative distance between the first connecting element 32 and the second connecting element 42 is increased, the push rod 20 cannot easily fall off from the linear bearing 33, or the relative movement between the first connecting element 32 and the second connecting element 42 is limited by the push rod 20. The base of the linear bearing 33 is connected with the deep groove ball bearing 34, and the deep groove ball bearing 34 is arranged in the extending direction of the axial lead of the linear bearing 33, so that the linear bearing 33 can rotate around the deep groove ball bearing 34, and the push rod 20 accommodated in the linear bearing 33 can rotate angularly around the deep groove ball bearing.
Accordingly, in order to achieve the above-mentioned characteristic that the push rod 20 performs angular rotation around the second connecting member 42, a preferred structure is provided in the present embodiment, which is described with reference to fig. 1 and 3, fig. 3 is a partially enlarged structural schematic diagram of the portion B shown in fig. 1, and as shown in fig. 3, the second connecting member 42 includes a knuckle bearing 43, an end of the push rod 20 is inserted into the knuckle bearing 43, and an inner ring of the knuckle bearing 43 is fixedly connected to the end of the push rod 20, so that the push rod 20 can perform angular rotation around the inner ring of the knuckle bearing 43.
Although the specific structures of the first connecting member 32 and the second connecting member 42 are given above, it is not limited that the first connecting member 32 and the second connecting member 42 can be implemented only by the specific structures, and on the contrary, in other specific embodiments, the first connecting member 32 and the second connecting member 42 can be implemented by other bearing-coupled mechanical structures which can satisfy the requirement that the push rod 20 can rotate angularly.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are, therefore, to be considered as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned. Furthermore, it will be obvious that the term "comprising" does not exclude other elements, units or steps, and the singular does not exclude the plural. A plurality of components, units or means recited in the claims may also be implemented by one component, unit or means in software or hardware.
