Description
Technical Field
The invention relates to the technical field of braille printing equipment, in particular to a braille printing device and a braille printing method.
Background
Braille is also called braille, braille and raised letters, is used by blind people, is invented by the Law of the French nationality and the Braille, and is formed by manufacturing different combinations of raised points on paper through a Braille plate, a Braille machine, a Braille printer and the like. The basic unit of braille is a rectangular blind symbol with six fixed points, each of which may or may not protrude, making 64 possibilities. The six points are distributed into two rows at the left and the right, and three layers at the upper, the middle and the lower. The left row is called 1, 2 and 3 points from top to bottom, and the right row is called 4, 5 and 6 points from top to bottom.
The Chinese braille schemes used in mainland China include the existing braille and the Chinese double-spelling braille. Currently, the current braille is more universal. Both braille types are phonographic characters and usually do not distinguish homophones (except when necessary). The numerical representations of the two schemes are the same and are both in the Braille form.
The printing of the braille is completely different from the printing of the common pictures and texts, the braille is composed of a plurality of convex points, namely convex points, which are arranged in different ways, and the blind can read by touching with fingers. The size, the dot pitch, the word pitch and the line pitch of the convex points are fixed during design according to the physiological and psychological characteristics of the touch of the blind, the convex points are generally hemispherical and parabolic, the diameter of the bottom of each convex point is generally 1-1.6 mm, the height of each convex point is 0.2-0.5 mm, and the dot pitch of each convex point is 2.2-2.5 mm. The convex points are too small and too close to each other, so that the touch response speed of the blind can be influenced, and if the convex points are too large, the convex points can exceed the most sensitive area of the touch feeling of the fingertips of the blind. The traditional braille printing method is the same as the common printing method, and a printing plate is also made firstly. The earliest braille printing plate is typeset by using the type of the lead, and then a sheet iron is changed into a punched sheet as a printing plate. Braille is punched on a sheet iron to form raised braille. Then fix the thin metal plate on the braille printer, impress the braille on the braille paper, make the paper surface form the protruding braille too. And after binding, the braille books are formed.
The existing Braille printing method has the solutions of mould impression, ink printing, foaming printing and the like, but the methods have a series of inconveniences such as time-consuming plate making, strict manufacturing process requirements, complex printing process, special printing paper and the like. Therefore, whether the improved braille printing device and the braille printing method can be provided based on the defects in the prior art or not is found to be an urgent technical problem to be solved by technical personnel in the field, and the technical problems of process simplification, production efficiency improvement and environmental protection are solved.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the braille printing device of the first embodiment includes: a paper feeding section 1, a printing section 2, a control section 3, and a paper receiving section 4. The paper feeding unit 1 is preferably a feeder unit, but is not limited to this, and other devices for feeding the loaded articles may be used. The printing section 2 is preferably a digital inkjet printer, but is not limited thereto, and other devices for braille printing on a support may be employed. The control section 3 is preferably a computer or similar electronic device for controlling the printing section 2 to perform braille printing in accordance with data imported from the outside. The discharge unit 4 is used to discharge the articles printed in braille by the printing unit 2, and the discharged articles are stored in a discharge tray. Preferably, the correction unit 5 may be provided, and the correction unit 5 is shown in fig. 1, but the correction unit 5 may not be provided, the correction unit 5 may be used to correct the positional information in the introduced data by scanning the loaded object, and the correction unit 5 is preferably an AIS (artificial intelligence scanner) that corrects the offset of the loaded object, but is not limited thereto, and other devices may be used. As support there can be selected paper, film, PVC, water-based coatings, hydrophobic materials where the oil-based coating is obtained by offset/screen/roller etc., and other coating materials, the thickness can be, for example, between 50 and 600 micrometers, and the size of the fed web is, for example, 750mm by 1200 mm. The gloss oil is not particularly limited, and various types of gloss oils can be used according to specific printing requirements. The printing unit 2 includes an ink jet unit that jets and prints varnish on a support, and a curing unit that irradiates the support on which the varnish has been jetted and printed to cure the varnish. The carrier is subjected to ink jet/irradiation while being conveyed without stopping the ink jet section and the curing section.
Further, it may be preferable to further include the corona unit 6, but the corona unit 6 may not be provided, and the corona unit 6 is used to change the surface tension of the support, preferably to increase the surface tension of the support.
As an example, the curing unit is explained below. The curing unit includes at least a Light-emitting diode (LED) lamp and an Ultraviolet (UV) lamp. The LED lamp cures the gloss oil surface (outer layer) and can prevent edge flow. The IR lamp heats the varnish, increasing its fluidity and allowing it to disperse.
The curing unit may further include an IR (Infrared) lamp. The control unit 3 controls parameters such as power of the LED lamp, the IR lamp, and the UV lamp in the drying unit, thereby being applicable to a plurality of different braille printing schemes. The LED lamp and the IR lamp are used for determining the height of the gloss oil on the bearing object. When the sprayed gloss oil is required to keep the original height (sprayed to a bearing object), the outer layer is cured by using an LED lamp, and then the whole gloss oil is cured by using a UV lamp. If the sprayed varnish is to be spread out, as in the case of coating, or if the diameter of the dripped varnish is to be increased (reduced in height), the purpose can be achieved by heating with an IR lamp.
The apparatus may further include a detection unit for detecting printed braille, and reporting an error or discharging an irregular braille formation to a different paper discharge tray between the curing unit and the paper discharge unit. The detection unit may be provided with a scanning unit for scanning the diameter of the braille, an ultrasonic sensor for detecting the height of the braille, or other devices for detecting the breakage of the braille.
