[0002]

[Prior art]

 The one using a bucket as a medal transportation means is proposed as Japanese Patent Application No. 4-31494. Its structure consists of a bucket that holds a plurality of objects to be transported such as medals, and a lid that opens and closes in parallel with the transport direction on one surface of the bucket. It is adapted to be driven by each separate drive means which can be closed thereafter.

[0003]

[Problems to be solved by the device]

 According to the above-described bucket-based transport means, the medal receiving hopper attached to the rail frame of the transport means supplies medals to the slot machine and the medal lending machine through the bellows, but a large amount of medals are received in the medal receiving hopper. There is a drawback that the medal receiving hopper is clogged because it flows in. A device that continuously supplies a small number of medals on a conveyor does not have a bridge, but it takes a long time and the supply speed is slow. When a large number (100 or more) of medals are replenished at one time by the above-mentioned transportation means, they bridge, so it is conceivable to install a vibrator or impeller on the medal receiving hopper, but each replenishment point should be provided individually. The installation of these will complicate the wiring inside the island, make the construction difficult, cause troubles, and further increase the cost. Moreover, the strength of the mounting part of the medal receiving hopper becomes more necessary. Furthermore, if there is only one mounting part for the medal receiving hopper, it cannot be used on the left and right sides of both islands in one form, and when mounting the hopper, the method of inserting the screw into the long hole and stopping it was complicated. . Therefore, it is an object of the present invention to obtain a medal receiving hopper which is not clogged with medals and has improved usability and which is easy to mount.

【Example】

 First, the medal transportation means will be described. In Figs. 12 and 13, (1) is a bucket that can store an arbitrary number of medals required by the replenishment destination such as a slot machine or medal lending machine. It stops at the supply destination that issued a request signal from the movement distance of the supply destination and supplies medals.After stopping at the supply destination, it can be opened and closed freely to drop the medals in the bucket to the medal receiving hopper (2). The lid (3) is at the bottom of the bucket (1) as shown in FIG. The bucket (1) and the lid (3) are simultaneously moved at the same speed by different driving unit transmission means, and the lid (3) is opened after stopping at the supply destination. A timing belt (4) is used as a driving means of the bucket (1), and the bucket (1) is fastened to the timing belt (4) via a mounting bracket (6). The lid body (3) is fastened to the timing belt (5) with the same structure as the bucket (1) is attached to the timing belt (4) via the mounting bracket (12) as shown in FIG.

The timing belts (4) and (5) are, as shown in FIGS. 12 and 13, a driving part (a) provided with a motor such as a stepping motor capable of performing accurate position control and a driven part (a driven part provided with a driven pulley on a frame). It is suspended between b) and. The drive part (a) of the timing belt (4) consists of a pulley (15) driven by a motor (13) through a speed reducer (14) as shown in Fig. 12, and between this and the driven pulley (16). It is stretched. The drive part of the timing belt (5) consists of a pulley (19) driven by a motor (17) through a speed reducer (18) as shown in Fig. 12, and is stretched between a driven pulley (20). Has been done. As for the timing belt (5), the drive section (a) and the driven section (b) are provided with the space adjusting pulleys (21) and (22) for keeping the space between the timing belt (4) as shown in FIG.

Reference numeral (23) shown in FIG. 15 is a frame body, and rails (24) and (26) for accommodating the timing belts (4) and (5) are provided on the frame body (23). In addition, a rail (27) that keeps the bucket (1) running while maintaining its independence is attached to the frame (23), and is fitted to the running rail (27) on the side of the frame (23) on the side of the bucket (1). Then install the linear slide (28) that drives the bucket (1). Further, the lid body (3) provided on the bottom surface of the bucket (1) slides along the slide rails (29) (30) provided on both side surfaces of the bucket (1). As shown in FIGS. 14 and 15, the supply bellows (2a) is attached to the medal receiving hopper (2), and the medal receiving hopper (2) is attached to the frame body (23). As shown in Fig. 16, a sensor mounting plate (32) is mounted below the traveling origin (c) on the drive side of the frame (23) shown in Fig. 15, and the deceleration position sensor (34) of the bucket (1) is attached to this. ), The stop position sensor (33) of the backing (1) and the stop position sensor (35) of the lid are attached as shown in FIGS. The above sensors detect the deceleration position of the bucket, the stop position, and the stop position of the lid (3) at the traveling origin (c). Corresponding to these sensors, a detection plate (38) for notifying the position of the bucket (1) is provided on the side surface of the bucket as shown in FIGS. The lid stop position sensor (35) is activated by the lid (3) itself. It is to be noted that the bucket (1) is prevented from traveling beyond the traveling origin (c) and the driven part (b) on the frame (23) in the drive part (a) and the driven part (b) as shown in Fig. 13. Overrun limit switches (36) and (37) are installed.

Now, a large number of medals are always put in the bucket (1) and stand by. Next, the bucket (1) is driven by a pulley (15) via a motor (13) and a speed reducer (14) by a timing belt (4) driven by a medal supply signal of a replenishment destination, and a linear slide with a traveling rail (27). It runs along the rail (27) with the fitting of (28). The lid (3) also moves at the same speed as the bucket (1) with the timing belt (5) driven by the pulley (19) via the motor (17) and the speed reducer (18). Then, it stops at the replenishment destination that generated the request signal from among the preset movement distances of the plurality of replenishment destinations. That is, the vehicle travels a predetermined distance according to a predetermined frequency and then stops. After stopping at the supply destination, the drive part of the lid operates for the set time, opens the lid body (3), and drops the medal of the bucket (1) into the medal receiving hopper (2).

After dropping the medal, the bucket (1) and the lid (3) are different drive units (13) (14) (15) and (17) (18) (19) and timing belts (4) (5), respectively. Then, at the same time, it returns to the origin (c) at the same speed as the drive (a). When the detection plate (38) passes the deceleration position sensor (34) of the bucket (1), the bucket (1) decelerates and the bucket (1) stops with the stop position sensor (33) of the bucket (1). To do. The lid (3) returns to the traveling origin (c) together with the bucket (1) while the lid (3) remains open, and the lid (3) stops when the stop position sensor (35) of the lid (3) is reached. However, since the lid (3) opens toward the origin, the lid first returns to the origin and stops, and then the bucket (1) returns. As a result, the lid body (3) closes as a slide inside the lid slide rails (29) (30) of the bucket (1). That is, the lid body (3) is stopped by its stop position sensor (35) first, and then the bucket (1) is stopped by its stop position sensor (33), thereby closing the lid body (3). . Of course, it is also possible to open the lid in the opposite direction and slide the lid on the bucket to close it. In addition to the method of closing the lid (3) as described above, the bucket first returns at the replenishment destination, and the bucket (1) and the lid (3) are closed after the lid (3) is closed. At the same time, it is possible to return to the origin (C) at the same speed.

When the bucket (1) and the lid (3) do not stop beyond the respective stop positions of the traveling origin (c) and the tension adjusting device (39), the overrun limit switch (36 ) (3 7) Touch the detection piece to stop. Here, the tension adjusting device is a device (39) for adjusting the tension of the timing belts (4) and (5) shown in FIG. 12 provided on the pulleys (16) (20) on the driven part (b) side. According to the above, since the bucket and the lid are moved and opened / closed by the drive unit (a) provided at the end, the bucket (1) and the lid (3) to be moved do not have the drive unit. Therefore, do not run around the drive cable.

The present invention relates to an improvement of the medal receiving hopper (2) in the above-described transport device. The medal receiving hopper main body (40) shown in FIG. 1 has a funnel shape as shown in FIG. 1, and a bounce portion (41) is formed in a spout shape on one side of the upper part and is made of a transparent synthetic resin. A screw (42) is engraved inside the lower part of the medal receiving hopper body (40), and a bellows connecting portion (44) having a plurality of slits (43) is formed. The inner diameter φ (d1) of the bellows connecting portion (44) is the same as the bellows inner diameter φ (d2), or the inner diameter φ (d2) of the bellows is large. A medal bridge preventing rod (45) is laid horizontally from the middle wall of the medal receiving hopper body (40) toward the medal rebounding part (41). The medal bridge prevention rod (45) shown in the figure has one end fitted in the wall hole (46) and the other end bent portion (47) fitted in the upper hole (48) of the base of the medal rebound portion (41). A pinching portion (49) is provided at the entrance of the stop hole (48) to prevent swinging. Further, there is a mounting part (52) for mounting on the carrier rail frame on the upper part of the medal receiving hopper body (40), and this has a long hole (50) for adjusting the mounting position. A reinforcing rim (51) is formed on 52. The medal bridge preventing rod (45) may have a mountain shape as shown in FIG. 4, a corrugated shape as shown in FIG. 5, or a cantilever beam shape as shown in FIG. is there.

As described above, since the medal bridge prevention rod (45) is provided in the middle of the medal receiving hopper main body (40), the medals thrown in from the bucket of the transport device are dispersed by the bridge prevention rod (45). The bridge phenomenon due to block formation does not occur, and the medal does not get stuck in the bellows connecting portion (44). However, assuming that the bridge prevention rods (45) are connected in the inclined direction of the medal bounce part (41), the medal bounce part (41) hits and descends along the inclined surface of the medal bounce part (41). However, since it is dispersed by the bridge prevention rod (45), the bridge phenomenon does not occur. In addition, since the medal receiving hopper body (40) is a synthetic resin molded product, the inner surface is slippery and the medal drops smoothly. Also, since the medal receiving hopper body (40) is transparent, the medal supply state can be visually checked. It is easy to take measures because it is visible even if a bridge occurs. Furthermore, in the lower bellows connecting part (44) of the medal receiving hopper body (40), the inner diameter of the connecting part is the same as the inner diameter of the bellows, or by making the inner diameter of the bellows large, it is possible to prevent slippage when the medal falls. Since the slits (43) are provided so as not to interfere with the operation, the bellows can be easily attached / detached to / from the medal receiving hopper main body (40).

In FIG. 7, if the medal receiving hopper main body (40) is formed into a quadrangle instead of a round shape and the traveling direction of the bucket is formed as shown by an arrow, the medal receiving area can be widened from the beginning. In addition to the mounting part (53), the mounting part (53) is symmetrically provided, and the mounting hole (54) of the bolt is cut out into an elongated hole. As shown in FIG. Can be attached. Further, since the wall can be formed by raising the lateral direction molding (57) of the medal receiving hopper, it is possible to prevent the medal from spilling from the side. When the elongated hole is notched, as shown in FIG. 11, the fixing screw (56) can be previously screwed into the frame (55) and the elongated hole (54) can be inserted into the frame (55) to be attached. If there is a method of inserting a screw into the long hole (50) and stopping it, it is necessary to support the hopper with one hand and tighten it with the other hand, and it is difficult to fit the screw to the tap. Also, since the position where the screw is tightened is shaded by the receiving hopper, the installation operation is complicated and uncomfortable. The one shown in Fig. 7 shows mounting parts (53) on the left and right and notched elongated holes (54) on both sides, so the mounting operation is simple and the same hopper can be installed on the left and right of both islands. Is convenient to use

[0015]

[Effect of device]

 According to the plan of the present invention, the medal bridge prevention rod is horizontally installed so as to be positioned diagonally with respect to the medal moving direction, and since it is located in the center of the main body of the medal receiving hopper, many medals are separated without forming a lump. Moreover, since there is a time lag, it drops smoothly without bridging to the outlet or bellows of the medal receiving hopper body. Also, since the medal receiving hopper body is made of a resin molded product, the inner surface is slippery and the medal falls smoothly. Further, in this plan, the mounting parts of the main body of the medal receiving hopper are provided symmetrically, so it is economical to use it with one type on both sides of both islands and it is economical, and the long holes cut out to the left and right of the mounting part. Since it is provided, the mounting operation becomes extremely easy. Furthermore, since the main body of the medal receiving hopper is transparent, the supply state of medals can be visually checked, and even in the unlikely event of a bridge, measures can be taken easily.
