1. Field of the Invention
The present invention relates to a shuffling and dealing device, and more particularly to an automatic shuffling and dealing machine that is convenient for card games.
2. Description of Related Art
Card shufflers have been known for a long time, e.g. U.S. Pat. No. 6,889,979 discloses a card shuffler comprises a drivable shuffling storage means, an input apparatus and an output storage means. The shuffling storage means has multiple compartments to receive and hold cards and is associated with the input apparatus for inserting cards into the compartments. The output storage means is separated from the shuffling storage means for the shuffled card. With the drive of the shuffling storage means and the input apparatus and the output storage means being controlled by an electronic control system, the cards discharging from the shuffling wheel will be in a random sequence. Therefore, the cards are completely shuffled.
Accordingly, the input apparatus has a draw-in zone with a height corresponding substantially to the thickness of a card. Such an arrangement guarantees that only one card at a time is conveyed to the shuffling storage means. However, since most modern playing cards are made of plastic, shuffling the playing cards may generate static electricity and make the playing cards stuck together. Additionally, the cards in the card shuffler are conveyed mostly in a straight manner. Consequently, the cards may easily coincide with or block to each other when conveying and eventually cause the card shuffler to breakdown.
Moreover, most components of the conventional card shufflers are driven by pulleys and toothed belts. Because the pulleys and the toothed belts stretch over time, gaps are inevitably formed between the pulleys and the toothed belts or elastic extension of the toothed belt, which cause the movement of the card shuffler to be less precise.
To overcome the shortcomings, the present invention provides an automatic shuffling and dealing machine to obviate or mitigate the aforementioned problems.
The main objective of the present invention is to provide a automatic shuffling and dealing machine that completely resolve the shortcoming of the conventional card shuffler.
To achieve the objective, the automatic shuffling and dealing machine comprises a card-input device, a shuffling device and an optional card-output device.
The card-input device has a first swiveling board, a guiding board, a first roller assembly and a first sensor. The first swiveling board is mounted slantwise, selectively sways and has a bottom edge and a surface. The front surface of the first swiveling board is attached with a static electricity mitigating sheet for a card stack to place on and mitigates static electricity of each card of the card stack. The guiding board is horizontally mounted securely in the card-input device adjacent the first swiveling board to form an inlet passage. The guiding board has a top surface and a semicircular-cross-sectional groove formed on the top surface corresponding to the bottom edge of the first swiveling board, such that when the card stack is placed on the first swiveling board, the card stack may insert in the groove. Therefore each card of the card stack will be in a position where an angle exists between two adjacent cards. That is, each card on top of one another is slightly staggered in relation to the card on the bottom of itself. In other words, two adjacent cards do not perfectly coincide with each other. Such ensure each card of the card stack to be drawn one by one.
The first roller assembly has multiple roller couples arranged adjacent to each other along the guiding board. Each roller couples has at least two rollers driven by a gear assembly connected with a motor. An attracting roller is arranged aligning to the surface of the first swiveling board. Such when the first swiveling board is activated to sway, the card stack will be pushed toward the attracting roller and the cards may be drawn into and conveyed along the inlet passage by the first roller assembly one by one.
The shuffling device has a stage, a shuffling wheel and a discharging rod. The stage is set stably on a planar surface and is attached with a controller and a primary power assembly. The primary power assembly is controlled by the controller and drives the shuffling wheel to rotate randomly and be temporarily held in an undetermined angle. The shuffling wheel is mounted rotatably on the stage and has multiple card slots formed diametrically around which, each of the card slots is selectively correspond to the inlet passage and stores at least one card being conveyed by the first roller assembly. The discharging rod is mounted pivotally on the stage and is driven by a driving motor to sway and has an arm protruding transversely from the discharging rod and selectively corresponding to one card slot of the shuffling wheel and discharges the card stored in the corresponding slot out.
The card-output device has a second roller assembly and a second swiveling board. The second roller assembly has a drawing roller and multiple roller couples arranged adjacent to each other. The roller couples of the second roller assembly has at least two rollers driven by a gear assembly connected with a motor. The second swiveling board is pivotally mounted slantwise and adjacent to the shuffling wheel for receiving the card discharged from the shuffling wheel and has a surface corresponding to one roller of the second roller assembly.
When a card is received on the second swiveling board, the received card will be in a slanted status that is not straight relative to the card slots, so an another card discharged later may not block to an edge of the received card. Then, The second swivel board can be activated to sway and push the received cards toward the drawing roller of the second roller assembly, such, one of the cards may be drawn into and conveyed by the second roller assembly at a time for dealing.
Obviously, the roller assemblies, the shuffling wheel and the discharging rod are driven via gears or directly by motors, so the automatic shuffling and dealing machine can motivate more precisely.
Moreover, since the first roller assembly or the second roller assembly draws the cards one by one, plus the arrangement of the static electricity mitigating sheet, the cards will not coincide with or block to each other when conveying and effectively prevent the automatic shuffling and dealing machine to breakdown.
