Description

Scanning and printing integrated machine with common power source

Technical Field

The invention relates to a scanning and printing all-in-one machine sharing a power source.

Background

Scanning and printing integrated devices typically include two main parts: one is a scanning device and the other is a printing device. The scanning and printing integrated apparatus is generally classified into two types according to the structure: the first is a scanning and printing integrated device with a scanning channel not directly communicated with a printing channel, and a typical example of the scanning and printing integrated device is a copying machine; the second type is a scanning and printing integrated device with a scanning channel communicated with a printing channel, and a typical example of the scanning and printing integrated device is a waste ticket processing device.

The operation of the first scanning and printing integrated device can be described by taking a copying machine as an example. When the copying machine works, an original document is firstly input into the scanning channel, original document information is obtained through the scanning device, then a printing medium is input into the printing channel, and the obtained original document information is printed on the printing medium through the printing device.

The operation of the second scanning and printing integrated device can be described by taking a waste ticket processing device as an example. The waste ticket processing device is typically used in the field of lottery tickets, but of course also in tickets, entrance tickets and even other fields of currency, securities, etc. When the lottery ticket waste processing equipment works, firstly, the prize-exchanging lottery ticket is input into the scanning channel, the information of the prize-exchanging lottery ticket is obtained through the scanning device, then the prize-exchanging lottery ticket is controlled to enter the printing channel from the scanning channel, and the printing device prints the waste mark on the lottery ticket after prize exchanging. However, the above-described lottery ticket discard processing apparatus has only a function of scanning a lottery ticket for redemption and a function of printing a mark on the scanned lottery ticket for redemption, and does not have a function of printing a lottery ticket. Therefore, at the lottery sales network, a special printer is required to be arranged for printing the lottery purchased by the customer; and a waste ticket processing device is needed to be arranged for completing lottery ticket exchange and printing a waste mark on the lottery ticket after the lottery ticket is exchanged.

According to the working process of the above waste ticket processing device, the second scanning and printing integrated device only has the scanning function and the function of printing marks on the scanned medium, does not have the printing function, and needs to be additionally provided with a printing device, so that the use is inconvenient, and the use cost is increased.

In addition, when different functions are realized, different power sources are often required to drive independent transmission systems, so that the structural design is complex, and meanwhile, the cost is increased due to the increase of the power sources.

and before the reversing mechanism is connected with the first paper guide roller, the second transmission chain reverses to retreat the paper to be printed into the second channel.

Compared with the background technology, the technical scheme has the following advantages:

1. the scanning and printing integrated machine not only can independently realize the scanning function and the printing function, but also can print on scanned paper and can additionally print after scanning, thereby being more convenient to use and lower in use cost. Meanwhile, the reversing mechanism selectively transmits the power of the main driving mechanism to the first paper guide roller and the second paper guide roller through the third paper guide roller, so that the first paper guide roller and the second paper guide roller can share one power source, the power source does not need to be separately arranged, the cost is greatly reduced, and the miniaturization can be realized.

2. The transmission process of the reversing mechanism is as follows: the reversing motor rotates to drive the reversing cam to rotate, the reversing cam rotates to drive the reversing swing rod to swing, the reversing swing rod swings to drive the reversing gear to swing, and then the reversing gear is in switching engagement with the first output gear or the second output gear, and therefore the first paper guide roller or the second paper guide roller rotates. The reversing structure is compact and simple, and the transmission effect is good and stable.

3. The stretching part stretches into the cam groove, and the cam groove is in a closed state and is the same as the cam body in shape, so that the cam groove is driven to rotate in the rotating process of the cam body, the stretching part is enabled to shift under the action of the cam groove, and the reversing swing rod can be driven to swing.

4. When the reversing gear is meshed with the first output gear in place or the reversing gear is meshed with the second output gear in place, the cam body triggers the signal sensor to stop the reversing motor from rotating, so that the rotation of the reversing motor can be controlled in time, and the phenomenon that the reversing gear is meshed with the first output gear or the second output gear excessively due to the excessive rotation of the reversing motor and then is disengaged is avoided.

5. The first paper guide roller comprises a first driving paper guide roller and a first driven paper guide roller, the second paper guide roller comprises a second driving paper guide roller and a second driven paper guide roller, and paper in the scanning channel can be conveyed towards the common channel under the clamping action of the first driving paper guide roller and the first driven paper guide roller, so that the normal operation of scanning is ensured; the paper in the printing channel can be conveyed towards the shared channel under the clamping action of the second driving paper guide roller and the second driven paper guide roller, and the normal printing is ensured.

6. The third paper guide roller and the scanning device are oppositely arranged, and a gap is reserved between the third paper guide roller and the scanning device, so that the scanning effect cannot be influenced by the fact that paper is separated from the focal range of the scanning device due to up-down floating when passing through the scanning device.

7. The printing rubber roller and the third paper guide roller share one main driving motor, so that the cost is further reduced, and the size is reduced.

8. When the reversing mechanism is connected with the first paper guide roller, the second transmission chain is reversed to retreat the paper to be printed into the second channel, thereby ensuring that no paper to be printed is in the shared channel when the first channel and the shared channel are used.

As shown in fig. 11, the transition section 25 is located to the right of the pressure point section 26 to facilitate the counter-clockwise rotation of the reversing cam 20. If necessary, the transition section 25 can also be located to the left of the pressure point section 26 to facilitate the clockwise rotation of the reversing cam 20; alternatively, transition sections 25 are provided on both the left and right sides of the pressure point section 26, so that the reversing cam 20 can rotate either clockwise or counterclockwise.

In practical design, the central angle a1 corresponding to the first circular arc segment 23 and the central angle a2 corresponding to the second circular arc segment 24 are both greater than the central angle a3 corresponding to the pressure point segment 26. It is ensured that the reversing gear 40 has engaged the first output gear 50 or the second output gear 60 before the activation of the subsequently involved first position switch 70 or second position switch 80.

In this embodiment, as shown in fig. 10, the reversing swing link 30 is provided with an extending portion 31, and the extending portion 31 extends into the cam groove 22.

In this embodiment, the reversing swing link 30 is substantially triangular, or may be linearly arranged, but not limited thereto. A rotating shaft hole 32 is formed at a first vertex angle of the reversing swing rod 30, the third paper guide roller 310 is in rotating fit with the rotating shaft hole 32 so that the reversing swing rod 30 can swing around the third paper guide roller 310, and the third output gear 90 is positioned on the outer side of the reversing swing rod 30; the second vertex angle is provided with the reversing gear 40, and the third vertex angle is provided with the extending part 31. As shown in fig. 10, the reversing gear 40 is located on the front side of the reversing swing link 30, and the protruding portion 31 is located on the back side of the reversing swing link 30.

In order to ensure that the reversing gear 40 can be meshed with the first output gear 50 or the second output gear 60 in place, the reversing structure is further provided with a first signal sensor and a second signal sensor, in the embodiment, the first signal sensor and the second signal sensor respectively adopt a first in-place switch 70 and a second in-place switch 80, the first in-place switch 70 and the second in-place switch 80 are respectively arranged on two sides of the cam body 21, when the cam body 21 triggers the first in-place switch 70, the reversing gear 40 is meshed with the first output gear 50 in place and the reversing motor 10 stops rotating, and when the cam body 21 triggers the second in-place switch 80, the reversing gear 40 is meshed with the second output gear 60 in place and the reversing motor 10 stops rotating.

As shown in fig. 6 and 7, the first in-position switch 70 is rotatably provided with a first trigger lever 71, and the second in-position switch 80 is rotatably provided with a second trigger lever 81. Because the outer periphery of the cam body 21 is provided with the transition section 25 and the pressure point section 26, the first in-place switch 70 or the second in-place switch 80 is firstly matched with the transition section 25 and the pressure point section 26, that is:

when the first trigger rod 71 is correspondingly matched with the transition section 25 in the rotation process of the cam body 21, the reversing gear 40 is meshed with the first output gear 50; when the first trigger lever 71 is correspondingly engaged with the pressure point section 26, the reversing gear 40 is engaged with the first output gear 50, the pressure point section 26 presses against the first trigger lever 71, the first trigger lever 71 generates a trigger signal, and the reversing motor 10 stops rotating after receiving the trigger signal; similarly, when the second trigger lever 81 is correspondingly engaged with the transition section 25, the reversing gear 40 is engaged with the second output gear 60; when the second trigger rod 81 is correspondingly engaged with the pressure point section 26, and the reversing gear 40 is engaged with the second output gear 60, the pressure point section 26 presses against the second trigger rod 81, the second trigger rod 81 generates a trigger signal, and the reversing motor 10 stops rotating after receiving the trigger signal.

Since the transition section 25 and the pressure point section 26 are arranged in a curved surface in consideration of the delay of the trigger signal, and at the same time, a1 and a2 are both larger than a3, it is ensured that the reversing gear 40 is already engaged with the first output gear 50 or the second output gear 60 before the first trigger lever 71 or the second trigger lever 81 is triggered.

The reversing mechanism is compact and simple, and has a good and stable transmission effect. And, by designing the cam body 21 and cooperating with the use of the first in-position switch 70 and the second in-position switch 80, perfect engagement between the direction changing gear 40 and the first output gear 50 or the second output gear 60 can be ensured.

The working principle of the printer is as follows:

taking the initial state as an example where the reversing gear 40 is engaged with the first output gear 50, assuming that the reversing mechanism is connected to the first paper guide roller in the initial state:

first, when copying after scanning is needed, scanning operation is firstly carried out:

at this time, the operation of retracting the paper of the paper roll needs to be performed first: the reversing mechanism performs reversing action to connect the second paper guide roller; then, the main driving motor 700 rotates reversely to drive the third paper guiding roller 310, the second paper guiding roller and the paper winding shaft 420 to rotate reversely, so as to rewind the paper of the paper roll and return the paper into the second channel 200; then, the reversing mechanism performs reversing action to connect the first paper guide roller;

the paper to be scanned is put into the opening 110 at the top end of the first channel, the scanning device 500 is started, the main driving motor 700 rotates in the forward direction, the main driving gear group 710 drives the third paper guide roller 310 and the printing rubber roller 720 to rotate in the forward direction, the third output gear 90 rotates under the action of the third paper guide roller 310, the reversing gear 40 is meshed with the first output gear 50, the first active paper guide roller 130 rotates to drive the paper to be scanned to be transmitted along the first channel 100 and the common channel 300, the paper to be scanned is scanned when moving to the scanning device 500, and the paper to be scanned continues to move to the tail end of the common channel 300 under the action of the third paper guide roller 310 and the printing rubber roller 720 until the scanning is finished;

then, a printing operation is performed: the reversing swing link 30 swings under the action of the reversing motor 10, the reversing gear 40 swings downwards until being meshed with the second output gear 60, at this time, the main driving motor 700 rotates forwards to drive the second driving paper guide roller 210, the third paper guide roller 310 and the printing rubber roller 720 to rotate forwards, paper in the paper bin 400 is clamped by the second driving paper guide roller 210 and the second driven paper guide roller 220 and is transmitted along the directions of the second channel 200 and the common channel 300, the paper passes through the third paper guide roller 310 and then moves to the printing device 400 to be printed, the paper moves to the tail end of the common channel 300 under the action of the printing rubber roller 720, and finally, the printing operation is finished by cutting through the cutter device 600.

Secondly, when only the printing operation is needed, the printing steps can be adopted; or, the paper to be printed may be placed at the top opening 110 of the first channel, the paper roll is retracted, the main driving mechanism is started to rotate forward to drive the first paper guiding roller, the third paper guiding roller and the printing rubber roller to rotate forward, and after the printing device is started to perform the printing operation on the paper, the printed paper is output from the outlet at the end of the common channel 300.

Thirdly, when only the scanning operation is needed, only the scanning step is needed.

Fourthly, when the paper to be scanned needs to be printed, the scanning operation is performed first, and when the paper is separated from the scanning device 500 but not separated from the printing rubber roller 720, the first transmission chain rotates reversely, the scanned paper retreats to the upstream of the scanning device 500, and the first transmission chain rotates forward again to drive the scanned paper to pass through the first channel 100 again to enter the common channel 300 and to perform the printing operation when the scanned paper passes through the printing device 400.
