Description

  The present invention relates to a kind of document processing apparatus, and more particularly to a kind of automatic document processing apparatus.

  Please refer to FIG. The figure is a known kind of automatic document processing apparatus 100 ', which is a paper separating module 1', a sensor 2 ', a paper feeding module 3', a paper processing module 4 ', a paper output module 5', and a paper feeding channel 6 '. A second drive system 7 'and a control system 8'. Among them, the separation module 1 'is provided with a separation roll 11' and a first drive system 12 'for driving the separation roll 11'. The sheet feeding module 3 ′ is provided with a sheet feeding main driving wheel 31 ′, a sheet feeding driven wheel 32 ′, a screw 33 ′, and a power mechanism 34 ′. One end of the screw 33 ′ is pivotally connected to the sheet feeding driven wheel 32 ′. The other end is connected to a power mechanism 34 ', and a substantially middle portion of the screw 33' is pivotally connected to a support seat (not shown). The document processing module 4 'can perform scanning, printing or copying.

  In the example of document scanning, when the automatic document processing apparatus 100 ′ is in operation, a plurality of documents (not shown) are placed on one side of the separation module 1 ′, and the drive system 12 ′ of the separation module 1 ′ is provided. When the paper roll 11 'is driven and rotated, a single document is transmitted along the paper feed channel 6', and when the front end of the document reaches the sensor 2 ', the sensor 2' controls the control signal. Then, the control system 8 'controls the second drive system 7' to drive and rotate the main feeding wheel 31 ', thereby transmitting the transmitted document downstream. When the front edge of the document is scanned by the document processing module 4 'and sent to the delivery module 5', the rear edge of the document is in the paper feed module 3 'portion, at which time the control system 8' activates the power mechanism 34 '. And the power mechanism 34 'rotates the screw 33', thereby generating a gap between the paper feeding driven wheel 32 'and the paper feeding main driving wheel 31', and independently sending the document to the paper output module 5 '. As a result, it is possible to reduce the retention of documents in the paper feed module 3 ′ and the paper output module 5 ′.

  However, the above-described well-known automatic document processing apparatus 100 ′ controls the distance between the feeding main driving wheel 31 ′ and the feeding driven wheel 32 ′ using the rotation of the screw 33 ′, and uses the paper for a long period of time. When the surfaces of the main driving wheel 31 'and the paper feeding driven wheel 32' are worn, the pressure (positive force) between the paper feeding main driving wheel 31 'and the paper feeding driven wheel 32' becomes insufficient, and the document can be stably transmitted. Disadvantageous. In addition, when the document enters the exit module 5 ', the exit module 5' and the paper feed module 3 'form a detent for the document due to the presence of errors.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic document processing apparatus that does not form a deterrence for a document and that can stably transmit a document with respect to the above-described drawbacks in the known technology.

  To achieve the above object, an automatic document processing apparatus provided by the present invention includes a control system, a first sensor, a paper feed module, a document processing module, and a paper output module.

The elastic mechanism is controlled by the control system. The document processing module is installed on one side of the paper feed module, and processes the document sent out by the paper feed module. The paper output module is installed at a downstream position of the document processing module, and the paper output module sends out the document processed by the document processing module.

  The automatic document processing apparatus of the present invention can realize elastic pressing on the paper feed driven wheel and the paper feed main drive wheel by an elastic mechanism, and before the paper passes through the paper feed module and enters the paper output module, Increase the pressure on the main feeding wheel of the driving wheel and reduce the pressure on the main feeding wheel of the feeding driven wheel after the paper enters the exit module, and finally reduce the retention on the paper and stabilize the paper transmission .

Yes.

  The paper feed stacker 1 is used to stack a plurality of papers 9, and the paper 9 has a paper front end 91 and a paper rear end 92. The paper removal module is used to transmit the paper 9 on the paper feed stacker 1 to the paper separation module 2. The paper separation module 2 includes a paper separation roll 21 and a stopper roll 22 positioned above the paper separation roll 21, and the stopper roll 22 is fixed to a support seat (not shown). The paper distribution module 2 is installed downstream of the paper removal module and the paper feed stacker 1. A meshing area between the stopper roll 22 and the paper separating roll 21 is a paper separating area, and the paper separating area is used to separate a plurality of papers 9. The stopper roll 22 generates a resisting force necessary for separating paper through a resistance torque provided by a torque component (not shown), and the stopper roll 22 can also be a stopper friction piece.

  When the separating roll 21 rotates counterclockwise, the lowermost sheet 9 located on the right side of the stopper roll 22 and the separating roll 21 and in contact with the separating roll 21 receives the frictional force of the separating roll 21. Driven downstream, the other portion of the paper 9 receives the resistance force in the reverse direction of the stopper roll 22, whereby the lowermost paper 9 is separated from the other paper by the paper separation module and fed through the paper separation area. It is transmitted to the paper module 4.

  The first sensor 3 is installed downstream of the separating module 2 and is installed on one side of the separating module 2. The first sensor 3 detects the paper 9, and when the paper 9 reaches the position where the first sensor 3 is located, the first sensor 3 transmits a control signal to the above-described control system.

  The paper feed module 4 is installed downstream of the first sensor 3 described above. The paper feed module 4 pivots on a paper feed main driving wheel 41, a paper feed driven wheel 42 installed on one side of the paper feed main driving wheel 41, and a paper feed driven wheel 42. It includes a contacted elastic mechanism 43. The elastic mechanism 43 includes a cylinder 430, a fixing rod 431, a sleeve 432, and a spring 433.

One end of the cylinder is pivotally connected to the feed follower wheel 42 described above, and the cylinder 430 is controlled by the control system described above. The spring 433 is accommodated in the sleeve 432, one end of the spring 433 is connected to the above-described fixing rod 431, and the other end abuts on one end of the sleeve 432. The second sensor 5 is installed downstream of the paper feed module 4, the second sensor 5 detects the paper 9, and when the paper 9 is sent to a position where the second sensor 5 is located, the second sensor 5 A control signal is transmitted to the control system described above.

  The document processing module 6 is installed downstream of the second sensor 5 and controlled by the control system described above, which scans the paper 9 fed by the paper feed module 4. The paper output module 7 is installed downstream of the document processing module 6. The paper output module 7 includes a paper output main driving wheel 71 and a paper output driven wheel 72 located on one side of the paper output main driving wheel 71. 7 sends out the paper 9 after scanning by the document processing module 6.

  The control system described above includes a controller 81, a first drive system 82 and a second drive system 83 controlled by the controller 81.

  Please refer to FIG. 2 to FIG. When the automatic document processing apparatus 100 of the present invention starts operation, the paper removal module sends at least one sheet 9 placed on the paper feed stacker 1 into the separation module 2, and the separation module 2 removes the sheet 9. When the paper front end 91 is sent to the position where the first sensor 3 is located, the first sensor 3 transmits a control signal to the controller 81, and the controller 81 controls the second drive system 83. Then, the rotation of the paper feeding main driving wheel 41 and the output main driving wheel 71 is started.
