Description

Technical Field

[0001] The present application relates to the technical field of medical printing devices, and in particular to a medical film printing device. Background Art

[0002] Medical film printers are indispensable imaging devices in the medical field. They can convert medical images into high-quality printed images to facilitate doctors' diagnosis and treatment. As the output medium of the printer, films are usually stored in the printer supply box in the form of dozens to hundreds of stacked sheets. Because the film is soft and thin, and the bending state is uncertain, it is easy for the films to stick to each other when left for a long time or in a humid environment. When output from the supply box, there are often duplicate sheets and / or skewed transmission, which will cause the film to fail to print or report an error after entering the print head, or cause the transmission channel to be blocked, and then the machine needs to be frequently started for inspection and maintenance, which reduces the processing efficiency of the printer and causes film waste.

[0003] To solve the above problems, some manufacturers use a film suction mechanism combined with a fan to take and deliver the film from the working platform (CN206406620U). Figure 1 The film printing device comprises a working platform 1, on which a plurality of films 8 are stacked, and baffles are arranged on the left and right sides of the working platform. Figure 1 The left baffle 2 and the right baffle 3 are provided, wherein the left baffle 2 is fixedly provided with a fan 4, and specifically, the height of the baffle is higher than the working platform 1. The air outlet of the fan 4 faces the stacking gap 81 of the film 8, and a film suction mechanism 6 is provided above the film 8, and the film suction mechanism 6 includes a suction cup 61, and a conveying mechanism 5 is provided in front of the film suction mechanism 6. The film 8 is stacked on the working table 1, and the suction cup 61 in the film suction mechanism 6 rotates along the rotation axis to suck up the film 8, and the fan 4 blows air to the film 8, allowing air to enter the part where the two films 8 are bonded, so that the two films 8 that are bonded together are separated.

[0004] To solve the above problems, some manufacturers use a paddle device combined with a fan (CN210377018U) to solve the above technical problems. Figure 2 , the film printing device has a transmission slice structure, such as Figure 2 As shown, the transmission film separation structure includes a paddle device 9 and an air supply device 10. The paddle device 9 includes at least one paddle for being arranged in the film box system 4. The paddle is always in contact with one end of the film 2 in the width direction. The end surface of the paddle for contacting the film 2 is in a continuous tooth shape, and the pitch of the saw teeth on each paddle can be different. The peeling angle (inclination angle) of each paddle can also be different. In this way, different paddle phase differences can be generated during the film peeling process, so that it is easier to peel off the sticky film. The air supply device 10 is used to be arranged in the medical dry film recording device 1. The air supply device 10 is used in conjunction with the paddle device 9 to provide film separation air to the film 2.

[0005] Although the above two solutions can reduce the occurrence of film adhesion to a certain extent, thereby reducing the probability of film doubling and / or skewed transmission, it is still impossible to avoid the occurrence of film doubling and / or skewed transmission. For example, two or more films are pasted too tightly, and the blower is not sufficient to separate the doubled films within the limited film conveying distance and time. Once such films are conveyed to the printing module, even if no channel blockage is caused during the conveying process, the films that have been thermally processed cannot be used again, resulting in waste of films. In addition, adding devices such as film suction devices and blowers not only increases the overall cost and size of the machine, but also increases the noise during the operation of the printer, which is not user-friendly. Summary of the Invention

Through the cooperative setting of a first film accommodating part, a second film accommodating part, a detection mechanism, and a diversion fork, it is possible to prevent overlapping films from entering the film output channel, causing blockage of the printing device or waste of films, and significantly reducing the maintenance time of the operator and the overall printing efficiency.

[0037] The following is a further detailed description of the present application in conjunction with the attached Figure 3 - attached Figure 7 to further elaborate on the present application.

[0038] The embodiment of the present application provides a medical film printing device, including a printer main body 10. Inside the main body 10, there are a conversion area 11, a detection mechanism 20 for detecting the state of the film, a first sheet holding part 30 for placing the film, a second sheet holding part 40 for storing abnormal films, and a printing mechanism 50 for printing the film;

[0039] At the outlet of the first sheet holding part 30, a main conveying channel 31 for conveying the film is connected and arranged. Inside the first sheet holding part 30, a first sheet splitting mechanism 60 for conveying the film is arranged. At the inlet of the second sheet holding part 40, a recycling channel 41 for recycling the film is connected and arranged. The conversion area 11 is located at the intersection of the main conveying channel 31 and the recycling channel 41. On one side of the conversion area 11, a sheet outlet channel 51 leading to the printing mechanism 50 is also arranged;

[0040] A lane-changing fork 12 with adjustable position is arranged in the conversion area 11. The lane-changing fork 12 can be in a first position or a second position within the conversion area 11. When the lane-changing fork 12 is in the first position, the film outlet channel 51 is communicated with the main conveying channel 31, and the recycling channel 41 is disconnected from the main conveying channel 31. When the lane-changing fork 12 is in the second position, the recycling channel 41 is communicated with the main conveying channel 31, and the film outlet channel 51 is disconnected from the main conveying channel 31.

[0041] The following is a further introduction in combination with specific usage scenarios.

[0042] In use, the first film storage part 30 is used for storing films. The detection mechanism 20 is arranged outside the first film storage part 30 and the second film storage part 40. When it is necessary to print a film, the first film splitting mechanism 60 is started to drive the uppermost film in the first film storage part 30 into the main conveying channel 31, and the detection mechanism 20 outside the first film storage part 30 immediately starts to detect the state of the film entering the main conveying channel 31 from the first film storage part 30.

[0043] When the detection mechanism 20 detects that the state of the film is a normal state, the lane-changing fork 12 moves to the first position, so that the film outlet channel 51 is communicated with the main conveying channel 31, and the recycling channel 41 is disconnected from the main conveying channel 31. The film enters the film outlet channel 51 from the main conveying channel 31 and is immediately printed by the printing mechanism 50;

[0044] When the detection mechanism 20 detects abnormalities such as film overlap, the lane-changing fork 12 moves to the second position, the recycling channel 41 is communicated with the main conveying channel 31, and the film outlet channel 51 is disconnected from the main conveying channel 31. The film in the main conveying channel 31 no longer enters the film outlet channel 51 for printing, but directly enters the second film storage part 40 for recycling, avoiding the blockage of the printing device or the waste of films caused by the overlapping films entering the film outlet channel 51, and significantly reducing the maintenance time of the operator and the overall printing efficiency.

[0045] As a feasible specific implementation manner of the embodiment of the present application, it further includes a second film splitting mechanism 70 arranged in the main conveying channel 31 for conveying films. The films in the first film storage part 30 sequentially pass through the first film splitting mechanism 60, the second film splitting mechanism 70 and the detection mechanism 20, and the films in the first film storage part 30 move in the main conveying channel 31 through the joint propulsion of the first film splitting mechanism 60 and the second film splitting mechanism 70.

[0046] Among them, the first film-splitting mechanism 60 includes a connecting rod 61 movably connected to the main body 10. A film-splitting roller 62 is provided at the end of the connecting rod 61. When the rotating film-splitting roller 62 contacts the upper-layer film of the first film-holding portion 30, the upper-layer film of the first film-holding portion 30 is separated. Specifically, when printing starts, the first film-splitting mechanism 60 rotates and presses downward along the arrow v1 direction. After contacting the uppermost film stored in the first film-holding portion 30, the film-splitting roller 62 in the first film-splitting mechanism 60 rotates along the arrow v2 direction, driving the film to be conveyed along the arrow v3 direction through the second film-splitting mechanism 70 towards the main conveying channel 31 direction.

[0047] The second film-splitting mechanism 70 includes a film-rubbing roller 71 and a film-blocking roller 72 movably connected to the main body 10. The film-rubbing roller 71 and the film-blocking roller 72 are respectively located on both sides of the main conveying channel 31. Both sides of the film entering the main conveying channel 31 are respectively in contact with the film-rubbing roller 71 and the film-blocking roller 72. The relative position between the film-rubbing roller 71 and the film-blocking roller 72 is adjustable. An adjusting mechanism 73 for lifting or lowering the film-blocking roller 72 can be provided on the film-blocking roller 72. When printing starts, when the detection mechanism 20 located on the downstream side of the film-feeding channel detects an abnormal signal near the head of the conveyed film and determines that there is a double-feed, at this time, the film-blocking roller 72 located below the channel lifts along the arrow v2 direction, penetrates into the film-feeding channel and squeezes the double-fed film with the film-rubbing roller 71. At this time, the film-rubbing roller 71 located above the channel still rotates along the arrow v1 direction, and relying on the difference in the friction coefficients between the films and between the film and the film-blocking roller 72, the double-fed film is separated. When the first double-feed detection mechanism 20 detects that the signal near the tail of the film is normal and determines that the double-feed has been separated, that is, single-sheet conveying of the film is achieved. At this time, the film-blocking roller 72 descends along the reverse direction of the arrow v2 through the adjusting mechanism 73 and withdraws from the inside of the main conveying channel 31 to avoid affecting the subsequent normal film conveying efficiency. Subsequently, the single-sheet film enters the main conveying channel 31, the diversion fork 12 remains in the first position, the film-out channel 51 is communicated with the main conveying channel 31, and the recovery channel 41 is disconnected from the main conveying channel 31. The single-sheet film is conveyed to the film-out channel 51, and the printing mechanism 50 located inside the film-out channel 51 executes the printing instruction. Then, the single-sheet film that has been printed is sent to the film-out port.

[0048] If the double-feed separation of the second film-splitting mechanism 70 fails and the signal near the tail of the film detected by the detection mechanism 20 is still abnormal, that is, the film is still double-fed. To avoid affecting subsequent printing, at this time, when the diversion fork 12 is in the second position, that is, the recovery channel 41 is communicated with the main conveying channel 31, and the film-out channel 51 is disconnected from the main conveying channel 31. The double-fed film enters the second film-holding portion 40 through the recovery channel 41 to prevent the double-fed film from being thermally processed by the printing mechanism 50, causing unnecessary film waste.

[0049] As a feasible specific implementation manner of the embodiment of the present application, the detection mechanism 20 includes a first double-sheet detection component 21 for detecting whether the films overlap. The first double-sheet detection component 21 is arranged in the main conveying channel 31. The first double-sheet detection component 21 is arranged downstream of the second sheet splitting mechanism 70. The first double-sheet detection mechanism 20 can be an ultrasonic sensor. Specifically, taking double sheets of film as an example, when the double sheets of film pass through the first double-sheet detection component 21, since they are of the same medium, the sound wave can continue to pass through the second superimposed film and be reflected on the bottom surface of the second film, extending the propagation time of the sound wave in the thin sheet-like medium. The recognition circuit immediately recognizes the time difference to achieve the purpose of double-sheet detection. Of course, the first double-sheet detection component 21 can also adopt a photoelectric sensor or a Hall sensor, etc. The double-sheet detection process and specific settings are well-known technologies to those skilled in the art and will not be elaborated herein.

[0050] Furthermore, the detection mechanism 20 further includes a skew detection component 22 for detecting whether the position of the film is skewed. The skew detection component 22 is arranged in the main conveying channel 31. Specifically, the skew detection component 22 is arranged between the double-sheet detection component and the conversion area 11, upstream of the diversion fork 12. The skew detection component 22 is used to detect the film head signal. When the detected value is lower than the first threshold, it indicates that the skew angle of the film meets the printing quality requirements. At this time, the diversion fork 12 remains in the first position, the film output channel 51 is communicated with the main conveying channel 31, and the recovery channel 41 is disconnected from the main conveying channel 31. The single sheet of film is conveyed to the film output channel 51, and the printing mechanism 50 located inside the film output channel 51 executes the printing instruction. Then, the single sheet of film that has been printed is sent to the film output port; when the detected value is higher than the first threshold, it indicates that the skew angle of the film does not meet the printing quality requirements. At this time, when the diversion fork 12 is in the second position, that is, the recovery channel 41 is communicated with the main conveying channel 31, and the film output channel 51 is disconnected from the main conveying channel 31. The double-sheet film enters the second film storage part 40 through the recovery channel 41 to prevent the double-sheet film from being thermally processed by the printing mechanism 50, causing unnecessary waste of film.

[0051] The detection mechanism 20 further includes a double-sheet detection component 23, which is arranged between the skew detection component 22 and the conversion area 11. Specifically, the double-sheet detection component 23 is arranged at the main conveying channel 31, upstream of the diversion fork 12, and is used to detect again whether the film conveyed to the main conveying channel 31 is double-sheeted. When the double-sheet detection component 23 detects that the signal near the head of the film is normal and determines that it is single-sheet conveyed, at this time, the diversion fork 12 remains in the first position, the film output channel 51 is communicated with the main conveying channel 31, and the recycling channel 41 is disconnected from the main conveying channel 31. The single-sheet film is conveyed to the film output channel 51, and the printing mechanism 50 inside the film output channel 51 executes the printing instruction. Then, the single-sheet film that has been printed is sent to the film output port. When the double-sheet detection component 23 detects that the signal near the head of the film is abnormal, that is, the film is still double-sheeted, at this time, when the diversion fork 12 is in the second position, that is, the recycling channel 41 is communicated with the main conveying channel 31, and the film output channel 51 is disconnected from the main conveying channel 31. The double-sheet film enters the second film storage part 40 through the recycling channel 41 to prevent the double-sheet film from being thermally processed by the printing mechanism 50, resulting in unnecessary film waste.

[0052] As a feasible specific implementation manner of the embodiment of the present application, it further includes a box full detection component 24, which is arranged inside the second film storage part 40 and is used to detect the nearly full state of the film in the second film storage part 40.

[0053] When the printing device is started or before the printing task is executed, the box full detection component 24 performs a detection action to detect whether the nearly full state of the film in the second film storage part 40 is higher than the second threshold. If it is higher than the second threshold, the user is prompted to clean the second film storage part 40 in time through the status indicator light, display screen, and sound arranged on the main body 10 of the medical film printing device. After cleaning, the box full detection component 24 performs a detection action again to detect whether the nearly full state of the film in the second film storage part 40 is higher than the second threshold. If it is lower than the second threshold, the printing task is executed. By arranging the box full detection component 24 in the second film storage part 40, not only can the film utilization rate be improved, but also the blockage of the recycling channel 41 caused by the second film storage part 40 being too full can be avoided, which is convenient for the user to use.

[0054] It further includes a film shortage detection component 25, which is arranged inside the first film storage part 30 and is used to detect the nearly empty state of the film in the first film storage part 30.

[0055] The first film accommodating part 30 further includes a first film accommodating box 30 and a second film accommodating part 40. The first film accommodating box 30 and the second film accommodating part 40 can accommodate films of the same specification size. The first film accommodating box 30 is provided with a first film shortage detection component 25, and the second film accommodating part 40 is provided with a second film shortage detection component 25. When the printing device is started and / or before printing is executed, the first film shortage detection component 25 and the second film shortage detection component 25 respectively detect the near-empty state of the films in the first film accommodating box 30 and the second film accommodating part 40. By way of example, when the near-empty state threshold detected by the first film shortage detection component 25 for the first film accommodating box 30 is lower than a third threshold, and the near-empty state threshold detected by the second film shortage detection component 25 for the second film accommodating part 40 is higher than a fourth threshold, the user is prompted by a status indicator light, a display screen, and a speaker provided on the main body 10 to replenish the film in the first film accommodating box 30 in a timely manner, and the film is conveyed through the second film accommodating part 40. When the near-empty state threshold detected by the first film shortage detection component 25 for the first film accommodating box 30 is lower than a third threshold, and the near-empty state threshold detected by the second film shortage detection component 25 for the second film accommodating part 40 is lower than a fourth threshold, the user is prompted by a status indicator light, a display screen, and a speaker provided on the main body 10 of the medical film printing device to replenish the films in the first film accommodating box 30 and the second film accommodating part 40 in a timely manner, the printing task is paused, and after the film is replenished, the printing task is resumed. By providing the film shortage detection component 25, in the case of multiple film accommodating boxes, not only can the near-empty state of the film accommodating boxes be timely reminded, but also the film can be preferentially supplied from the film accommodating box without a film shortage, avoiding the user's ineffective waiting time.

[0056] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
