BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates a card-delivering device, especially to a card-delivering device for a shuffling machine to deliver cards smoothly.
2. Description of the Prior Arts
Shuffling machines are widely used in casinos. With reference toFIG. 8, a shuffling machine comprises a shuffler (70), a card input (80) and a card output (90). The shuffler (70) is connected between the card input (80) and the card output (90). Cards are put into the card input (80). The card input (80) delivers the card to the shuffler (70). The shuffler (70) has a controller to drive the shuffler (70) to rotate in a random direction so that the cards are mixed. Then the cards are output from the card output (90).
With further reference toFIG. 9, the card input (80) comprises a frame (81), multiple roller groups (82), a gear group (83) and a slide (84). The frame (81) is connected with the shuffler (70) and has a channel (811). The roller groups (82) are mounted in the frame (81). The gear group (83) is connected to and drives the roller groups (82). The slide (84) slides along the channel (84) and selectively pushes cards to pass through the roller group (82) into the shuffler (70).
However, the slide (84) cannot sift cards one by one and pushes multiple cards in the frame (81) to move toward the roller groups (82). Then more than one card may pass through the roller groups (82) to be delivered into one card slot of the shuffler (70). Therefore, the cards may not be output one by one. Such disordered card output may nullify a card game and cause casinos to lose reputation and customers.
To overcome the shortcomings, the present invention provides a card-delivering device for a shuffling machine to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the present invention is to provide a card-delivering device for a shuffling machine that precisely delivers cards passing through in order. The card-delivering device has a frame, at least one drawing roller group, a drawing transmission, an actuating roller group and an actuating transmission. The frame has a pivoting panel with a magnet. The drawing roller group is mounted in the frame near the output end. The drawing transmission drives the drawing roller group. The actuating roller group has a magnetic roller corresponding to the magnet. The actuating transmission drives the actuating roller group. When the magnetic roller is rotated, the magnetic roller alternatively attracts or repulses the magnet to cause the pivoting panel to pivot. Therefore, cards pass between the magnetic roller and the pivoting panel in order when a gap between the magnetic roller and the pivoting panel is formed.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSWith reference toFIGS. 1 to 4, a card-delivering device for a shuffling machine in accordance with the present invention comprises a frame (10,10A), at least one drawing roller group (20,20A), a drawing transmission (30,30A), an actuating roller group (40,40A) and an actuating transmission (50,50A).
With further reference toFIG. 5, the frame (10,10A) has an input end (11,11A), an output end (12,12A), two side panels (13,13A), a receiving panel (14,14A), a pivoting panel (15,15A) and at least one magnet (16,16A). The receiving panel (14,14A) is mounted securely between the side panels (13,13A) near the input end (11,11A). The pivoting panel (15,15A) is mounted pivotally between the side panels (13,13A) near the input end (11,11A), is mounted above and selectively abuts the receiving panel (14,14A) and has an abutting end (151,151A). The magnet (16,16A) is mounted in the pivoting panel (15,15A) near the abutting end (151,151A).
The at least one drawing roller group (20,20A) is mounted in the frame (10,10A). Each drawing roller group (20,20A) has a top roller assembly (21,21A), a bottom roller assembly (22,22A) and a gap (23,23A). The top roller assembly (21,21A) is mounted rotatably between the side panels (13,13A) near the output end (12,12A). The bottom roller assembly (22,22A) is mounted rotatably between the side panels (13,13A) near the output end (12,12A) and is mounted adjacent to the top roller assembly (21,21A). The gap (23,23A) is formed between the top and the bottom roller assemblies (21,21A,22,22A), aligns with the receiving panel (14,14A) and allows one card to pass through.
The drawing transmission (30,30A) is connected to and drives the at least one drawing roller group (20,20A) and has a motor (31,31A), a drive gear (32,32A) and a driven gear set (33,33A). The motor (31,31A) is mounted in the frame (10,10A), may be attached securely to one side panel (13,13A) and has a driving shaft (311,311A). The drive gear (32,32A) is connected to and is driven by the driving shaft (311,311A). The driven gear set (33,33A) is driven by the drive gear (32,32A), is connected to and drives the at least one drawing roller group (20,20A) and has at least one driven gear (331,331A). Each driven gear (331,331A) is driven by the drive gear (32,32A) and is connected to and drives a corresponding drawing roller group (20,20A).
In one preferred embodiment, each driven gear (331) engages the drive gear (32). The driven gear (331) is connected to and drives the bottom roller assembly (22) of the corresponding drawing roller group (20)
In another preferred embodiment, a transmitting gear (332A) engages and is connected between the driven gear (331A) and the drive gear (32A) so that the drive gear (32A) drives the driven gear (331A) through the transmitting gear (332A). The driven gear (331A) is connected to and drives the top roller assembly (21A) of the corresponding drawing roller group (20A).
The actuating roller group (40,40A) is mounted in the frame (10,10A) and has a central rod (41,41A), a magnetic roller (42,42A) and multiple auxiliary rollers (43,43A). The central rod (41,41A) is mounted rotatably between the side panels (13,13A) near the input end (11,11A). The magnetic roller (42,42A) is mounted securely around the central rod (41,41A) and corresponds to and alternatively attracts or repulses the magnet (16,16A). The auxiliary rollers (43,43A) are mounted securely around the central rod (41,41A).
The actuating transmission (50,50A) is connected to and drives the actuating roller group (40,40A) and has a motor (51,51A), a drive gear (52,52A) and a driven gear (53,53A). The motor (51,51A) is mounted in the frame (10,10A), may be attached securely to one side panel (13,13A) and has a driving shaft (511,511A). The drive gear (52,52A) is connected to and is driven by the driving shaft (511,511A). The driven gear (53,53A) engages the drive gear (52,52A) and is connected to and drives the central rod (41,41A) of the actuating roller group (40,40A). When the actuating transmission (50,50A) drives the central rod (41,41A) of the actuating roller group (40,40A) to rotate, the magnetic roller (42,42A) is rotated to selectively attract or repulse the magnet (16,16A) and the pivoting panel (15,15A) is pivoted by the attraction or the repulsion.
With further reference toFIG. 6, the card-delivering device for a shuffling machine as described may be implemented as a card input (100) or a card output (100A) and is connected to a shuffler (60).
With reference toFIG. 5, the magnetic roller (42,42A) attracts the magnet (16,16A) so that no gap is formed between the magnetic roller (42,42A) and the pivoting panel (15,15A). Therefore, cards being placed on the pivoting panel (15,15A) are stopped before the magnetic roller (42,42A).
With further reference toFIG. 7, the magnetic roller (42,42A) repulses the magnet (16,16A) so that a gap is formed between the magnetic roller (42,42A) and the pivoting panel (15,15A) to allow one card to pass through. Therefore, one card being stopped before the magnetic roller (42,42A) drops on the receiving panel (14,14A) and is delivered by the drawing roller group (20,20A).
With the cooperation between the magnetic roller (42,42A) and the magnet (16,16A), the cards placed on the pivoting panel (15,15A) are delivered one by one toward the drawing roller group (20,20A). Therefore, the cards are delivered into the shuffler (60) one by one and are delivered out of the card output one by one.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
