Description

Playing card turning and feeding method Technical Field The invention belongs to the technical field of poker machines, and particularly relates to a method for turning and delivering playing cards. Background The card arranging machine generally refers to a mahjong machine, a domino machine, a poker machine or the like. Taking a poker machine as an example, a total of 54 poker cards are taken as a poker card, the poker machine can automatically deal the poker cards into a card discharging device through a card dealing mechanism and send the well-dealt poker cards to a table top through a card lifting plate, a user does not need to manually deal or take the poker cards one by one, and the poker card dealing machine can save time and has fairness randomly. Before dealing the playing cards from the dealing mechanism to the card dealing device, the dealing of the playing cards is guaranteed to be downward through the processes of dealing, turning and the like, so that the follow-up users can carry out entertainment activities conveniently. The existing poker machine also needs to pass through a conveying mechanism and identify the front and back sides of the poker cards before the poker cards are sent into a card outlet mechanism, and then the poker cards are conveyed to a card turning mechanism and are turned back according to the requirements, but the existing conveying mechanism and card turning mechanism are complex in structure, many in moving parts and large in occupied space. And when the existing poker machine is used for arranging the poker, the poker is firstly sent to the poker turning mechanism through the card outlet mechanism to be identified and turned, then is directly sent to the poker dealing device to deal, the poker directly enters the poker dealing device after being turned, the situation that the poker is scattered possibly occurs, the dealing is inconvenient, and the poker is possibly sent to the poker dealing device without being completely turned due to the fact that the card turning speed is high, and then the situation of card is caused. Disclosure of Invention Aiming at the technical problems that in the prior art, cards are easy to appear in the processes of card feeding, card turning and card dealing, the playing cards are scattered and the card dealing efficiency is low, the invention aims to provide a card turning and card feeding method. The playing card turning and feeding method comprises the following steps: Step S1, a front and back recognition sensor of a card feeding end at the upstream of a card feeding mechanism recognizes the front and back of playing cards at the upstream of the card feeding mechanism; Step S2, according to the front and back sides of the identified playing cards, the playing cards are selectively turned over or not turned over by a card turning mechanism in the middle of a card feeding mechanism, and are conveyed to the downstream of the card feeding mechanism and are in a state of facing downwards; And S3, dealing the playing cards with the front faces facing downwards at the downstream of the card sending mechanism. Preferably, the step S3 specifically includes: Downstream of the card delivery mechanism, the card is delivered to the card delivery mechanism with the face down playing card. Preferably, the method further comprises: and S4, dealing the playing cards by a card outlet mechanism. Preferably, step S2 further comprises: step S2a, if the identified playing card is downward in the front, the card turning mechanism is always in an initial state and is directly conveyed from the upstream of the card conveying mechanism to the downstream of the card conveying mechanism; if the identified playing card is right-side up, the playing card is conveyed to the card turning mechanism from the upstream of the card feeding mechanism, and the card turning mechanism turns the playing card with the right-side down from the initial state in the air to the downstream of the card feeding mechanism to enable the playing card to be in the right-side down state. Preferably, the substep S2a is specifically: The turner rod of the card turner is always in an initial state, and the first conveyor belt at the upstream of the card feeding mechanism directly conveys the playing cards with the front faces downwards to the second conveyor belt at the downstream of the card feeding mechanism. Preferably, the substep S2b comprises: Step S21, a first conveyor belt at the upstream of the card feeding mechanism conveys the playing cards with the right sides upwards to a card turning rod of the card turning mechanism; In step S22, the playing cards with the front faces upwards are carried by the card turning rod of the card turning mechanism in the initial state and turned over in the air around the rotating shaft to the position above the downstream of the card feeding mechanism, so that the playing cards lie on the second conveyor belt in a state of being front faces downward
