Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention provides a method for printing lottery tickets such as treasure baskets with letters and symbols that indicate wins and losses, in addition to the lottery numbers. This invention relates to a device for peeling off and crushing the concealing ink layer of a basket ticket, which is equipped with a scratch-off double lottery function that hides the letters and symbols of winnings and misses by solid printing a concealing ink such as silver ink.

(Problem that the invention seeks to solve).

As shown in FIG. 5, conventionally, a double lottery ticket (1) equipped with a scratch-off function has a scratch-off ink solid printing surface [bl, which hides the lottery number (al) and the display of winning or losing, and if necessary, Separate perforation according to IC
Prepare the lottery number [al] and check if it is a hit or miss.
For sucranothiophore by hand. Solid ink printing surface (b
Scrape off the hiding ink layer of l. I was checking the display prompts for hits and misses. Furthermore, when a large number of tickets are collected at a predetermined location such as a lottery booth, the concealing layer must be peeled off by hand for each ticket, which requires a great deal of effort.

(Object of the Invention) In order to solve the above-mentioned inconvenience, the present invention feeds a large number of lottery tickets one by one using a feeder before being peeled off.
While being conveyed on a belt, a polishing roller such as a wire brush roller that rotates at high speed makes contact with the lottery ticket surface, scraping the concealing ink layer, peeling it off and pulverizing it, and then pulverizing the ink powder that adheres to the ticket. The purpose is to efficiently remove concealing ink at high speed by sweeping it away with a brush of low rigidity.

(Structure of the Invention) The present invention comprises: upper and lower feed rollers that feed out sheets, an upper presser roller that rotates at the same speed as the roller feed speed (■), and a roller and a transfer sheet that are arranged opposite to each other on the lower side of the roller. A polishing roller which is in contact with the conveying surface and whose peripheral speed can be switched between the delivery speed M and the high speed by a photoelectric detector and a timer operation, a north discharge roller, and a polishing roller on the lower side facing the polishing roller. With repetitive brush and lower discharge wheel? A round belt for conveyance is provided in sequence, and is wound endlessly between both ends of the upper delivery roller and the upper discharge roller. This is a concealing ink film stripping device with unique features.

(Embodiments and operations of the invention) An embodiment of the invention will be described in detail with reference to the drawings. As shown in FIG.
