Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a rotary disk drive device for a clay dispensing machine.

As shown in Fig. 1, in the rotary disk drive device of the conventional clay discharger, the ratchet device 5 protrudes from the lower surface of the disk 3, so the head H' required to drop the clay 2 from the disk 3 until it is received by the vane plate is large. As a result, cracks and misalignment of the falling position occur due to falling during clay setting, and this misalignment of the falling position increases the dispersion in the direction of discharge of the clay, and the clay 2 collides with the side wall of the blade plate and breaks immediately before being discharged. Therefore, for the shooter who is mentally focused and waiting, the cracking of the clay 2 or the clay 2 flying out in a direction different from the direction in which it is waiting causes distraction, which is bad for clay target practice. It was affecting me.
For this reason, there are some cases in which an air nozzle or the like is installed and air is injected from one direction of the clay falling position to force the clay 2 to be in a fixed position, but even this method does not prevent the clay 2 from falling due to the head H'. Cracking could not be prevented, and the cost of installing an air injection device was high.

FIG. 2 is an explanatory diagram showing a discharge mechanism of a conventional clay discharger. In this conventional clay discharge mechanism, first, when the solenoid 17 is activated, the operating piece 15 is separated from the claw portion of the rotating body 14 with a claw. Then, the clay release spring 18 contracts and the blade plate 19
Instantly rotates and releases clay 2. At this time, the chain 13 is pulled at once by the elastic force of the clay release spring 18. Along with that, Rod 11
Since the driving lever 8, which is constantly connected to the protruding piece 11b provided at the top and swings, applies a direct discharge impact to each component that is linked to the driving lever 8, the stacked clays 2 are very easy to break, and each part is damaged. There were drawbacks such as loosening of interlocking parts and breakage of parts. The present invention was devised in view of the above-mentioned drawbacks, and in order to solve this problem, the ratchet device is provided above the lower surface of the disk, and the drive lever is shortened so that it does not come into contact with the protruding piece. A return spring is attached, and the tip of the drive lever is provided with a swingable claw that can be contacted by the projecting piece and can escape only in the direction of contraction of the rod. It is an object of the present invention to provide a rotary disk drive device for a clay discharger in which each member does not directly receive a discharge impact by having a structure in which the clay discharger is separated from the protrusion.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a disk-shaped rotary disk made of light metal or light alloy. A desired number of holes 1c for dropping the clay 2 are bored in the outer periphery of the hole 1b and the boss 1a, and an appropriate number of outer frame supports 1d for stacking the clay 2 are provided around the holes 1c. It has been erected. Reference numeral 3 designates a metal disk, which has a boss portion 3a protruding from the center thereof, a bearing 4 on its inner diameter, and a hole 3b for the clay 2 to fall into the outer periphery of the rotary disk 1. The hole is slightly larger than the hole 1c. A ratchet device 5 is also built into the inner diameter of the disk 3. The ratchet device 5 includes a pawl wheel 51.
, an inner pawl ring 52 and an operating rod 53. The configuration of this ratchet wheel device 5 will be explained in detail based on FIG.
1a and a disc portion 51b, the stepped shaft portion 5
A screw thread is carved at the tip of 1a, and a disc part 51b
is provided with a pair of claws 51c that face each other in the radial direction. The inner claw ring 52 has a flange shape, and a rotary disk 1 is mounted on the inner wall of the inner claw ring 52.
The same number of claw shapes as the holes 1c are formed. The operating rod 53 is provided with a protrusion 53a on the upper surface of the end.
A hole 53b is bored in the center of the hole 53b, and the protrusion 5
The lower surface of the end opposite to 3a is fixed to an inner pawl ring 52. When installing the claw wheel 51, insert the inner claw ring 52 and align the claws 51c so that they can be locked, and then insert the stepped shaft portion 51a into the bearing 4 built into the disc 3 and the rotating shaft. Hole 1b of board 1
The washer 6 is inserted from the tip of the stepped shaft portion 51a, and the nut 7 is screwed into place. At this time, the lower surface of the claw wheel 51 and the inner claw ring 52 are mounted so that they do not protrude from the lower surface of the disc 3. 8 is a drive lever, and the drive lever 8 is
Its length is shortened so that it does not come into direct contact with a protrusion 11b, which will be described later, and a pin 8a is provided upright at one end of the drive lever 8, and the pin 8a is connected to the hole 53b of the protrusion 53a of the operating rod 53. Inserted. 8b is a pin located at the center of the drive lever 8, and its position is directly below the center of the disk 3. Reference numeral 9 denotes a swingable claw that is pivotally supported at the tip of the drive lever 8 by a pin 8c, and the free claw 9 can come into contact with the protrusion 11b, so that the drive lever 8 is prevented from escaping in the direction of extension of the rod.
It is fixed by a stopper pin 8d protruding from the rod 11a, and is attached so that it can escape only in the direction of contraction of the rod 11a. Further, the length of the adjustable claw 9 is such that it separates from the protruding piece 11b during the extension of the rod 11a. Note that 8e is a spring for returning the drive lever 8. 10 is a spring for providing elasticity so that the free claw 9 is always in contact with the stopper pin 8d; 11 is a rod 1;
It is a cylinder with a protruding piece 11b provided on the tip side of 1a. Reference numeral 12 is a body, and reference numeral 13 is a chain connected to the tip of the rod 11a.The other end of the chain 13 is fixed to a side wall of a rotary body 14 with claws. The claw portion of the claw-equipped rotating body 14 engages with an actuating piece 15, and a spring 16 is attached to one end of the actuating piece 15.
The other end is connected to the solenoid 17. Reference numeral 18 denotes a clay release spring attached to the side wall of the rotating body 14 with claws, and the clay release spring 1
8 is for instantaneously rotating the vane plate 19.

Next, the operation of the present invention will be explained based on FIGS. 3 and 4. First, when the drive lever 8 is rotated around the pin A8b, the operating rod 53 rotates in the direction of the arrow, and the operating rod 53 rotates in the direction of the arrow. 53 is fixed to the inner claw ring 52, the inner claw ring 52 is rotated in the direction of the arrow. Then, the clawed wheel 51 receives rotational force from the inner claw ring 52 via the claw 51c and rotates, and since the clawed wheel 51 is fixed to the rotating disk 1, the rotating disk 1 also rotates at the same time, and the clay 2 When it reaches hole 3b, it passes through hole 1c and hole 3b and falls onto impeller 19. Furthermore, clay 2 is impeller 1.
Since the mechanism of falling onto 9 is well known, further explanation will be omitted. Next, when the drive lever 8 is returned to the initial position, the pawl 51c escapes inwardly against the rotation of the inner pawl ring 52, so that the pawl wheel 51 is not rotated and operates intermittently. At this time, the claw 51c is locked with the next claw-shaped portion of the inner claw ring 52.

Next, a drive lever 8 with a flexible claw 9 protruding from its tip
The operation of the rod 11a provided with the protruding piece 11b will be explained in detail. By operating the cylinder 11 in advance and contracting the rod 11a, the clay release spring 1 is released through the chain 13.
Extend 8. First, when the solenoid 17 is activated by the shooter's signal, the actuating piece 15 moves to the rotating body 1 with a claw.
At the same time as the clay release spring 18 is released from the claw part 4, the extended clay release spring 18 contracts, instantly rotating the blade 19, and the clay 2 is released (Fig. 2,
(See Figure 7). At this time, the chain 13 is also pulled at once by the elastic force of the clay release spring 18, and the rod 11a of the cylinder 11 begins to extend. As the rod 11a is further extended, the protruding piece 11b is pushed while coming into contact with the free claw 9 whose escape is prevented by the stopper pin 8d, thereby rotating the drive lever 8. However, during the complete extension of the rod 11a, the adjustable claw 9 separates from the projection 11b. [See Figure 6a]. When the free claw 9 is released, the drive lever 8 is returned to its original position by the return spring 8e [Fig. 6b
reference]. However, at this time, the rod 11a has not finished stretching yet, so it continues to stretch, and when it finishes stretching, the reaction force of the clay release spring 18 is
3 to reach the rod 11a. However, at this time, the free claw 9 and the protruding piece 11b have already been removed, so that the shock emitted from the drive lever 8, which conventionally occurs, is not directly applied to the interlocking parts.

After releasing the clay, the chain 1 is activated by activating the cylinder 11 and contracting the rod 11a.
3 to extend the clay release spring 18. During this process, the free claw 9 once hits the protrusion 11b and escapes (see FIG. 6c). However, the free claw 9 is immediately moved by the spring 10 to the driving lever 8.
It is returned to its original position and becomes ready for engagement with the protruding piece 11b. [See Figure 6d]. The subsequent operations repeat the above operations.

In this way, the present invention can eliminate protrusion from the bottom surface of the disk 3 by providing the ratchet device 5 above the bottom surface of the disk 3, and the head height H of the device of the present invention shown in FIG. Comparing the conventional head H' shown in Fig. 1, the head of clay 2 is almost half, which reduces the variation in the falling position when the blade 19 of clay 2 is set, and also prevents cracking and cracking during release. It is extremely small, and the conventional air injection device for stabilizing the direction at the time of ejection becomes unnecessary, making it possible to reduce the number of parts and product cost. In addition, by providing the drive lever 8 with a flexible claw 9, the drive lever 8 is not directly affected by the ejection impact, so there is almost no chance of loosening of fasteners or breakage of parts, and there is also no possibility of malfunction of the clay ejector or damage to the clay 2. There are no interruptions in practice due to cracks, etc., and the practical effects are great, such as making it really easy for archers to practice.
