Description

  The present invention is attached to a game ball lifting and polishing device that polishes a game ball by stirring the game ball and abrasive grains, and inputs a powdery antistatic agent that prevents the game ball from being charged with static electricity. The present invention relates to an antistatic agent charging device.

  Conventionally, in the game ball lifting and polishing apparatus, when the game ball and the abrasive grains are agitated, a powdery antistatic agent is introduced so that static electricity is not charged to the game ball. Since the input is performed artificially, there are cases where the user forgets to input at the time when it should be input or the amount to be input is wrong.

  In order to improve such a situation, for example, in order to automatically load laundry powder detergent, a motor is driven to rotate a coil which is a detergent transport means, and the powder detergent is transported by the coil and discharged. It is also conceivable to apply a technique such as that described in Patent Document 1 disclosed for the above.

JP 2002-102589 A

  However, the antistatic agent used in the game ball lifting and polishing apparatus has a property that it is likely to be hardened by the influence of temperature and humidity as compared with the washing powder detergent, and transports the antistatic agent having such a property. In such a case, if only the function of promoting the conveyance is provided as in Patent Document 1, the antistatic agent that is hardened (or contains a lot of moisture) blocks the discharge port, etc., so that a stable amount of antistatic is always provided. As a result, the antistatic agent cannot be discharged or the antistatic agent is biased to the vicinity of the discharge port. As a result, the antistatic agent is solidified so as to ride on the transport accelerating portion, and may stay without being discharged indefinitely. was there.

  In addition, if an amount of antistatic agent larger than the prescribed amount is introduced into the game ball lifting and polishing apparatus, the antistatic effect is not improved, and an excessive amount of antistatic agent is necessary on the surface of the game ball. Since the game balls are dirty by the adhesion, it has been desired that an appropriate amount of the antistatic agent can be introduced without fail.

  The present invention has been made paying attention to the problems of the prior art as described above, and is an antistatic agent having a property of easily solidifying when a powdered antistatic agent is introduced into a game ball lifting and polishing apparatus. Even so, it is an object of the present invention to provide an antistatic agent charging device capable of discharging a stable amount of the antistatic agent without staying in the vicinity of the discharge port.

A lid (13) having a ceiling surface (13a) close to the outer periphery of the upper half on the terminal end (22) side of the coil spring is arranged above the discharge port (17) [6. ] Antistatic agent charging device (10).

The present invention operates as follows.
According to the antistatic agent charging device (10) described in the above [1], the antistatic agent is attached to the game ball lifting and polishing device (1), and the antistatic agent storage unit (11) stores the powdery antistatic agent. When the motor (19) is driven, the conveyance promoting portion (20) is rotated by the driving force of the motor (19). The antistatic agent stored in the antistatic agent storage unit (11) is conveyed toward the discharge port (17) by the rotation-driven conveyance promoting unit (20).

  Here, on the front side of the discharge port (17), a conveyance suppression unit (45) that suppresses conveyance of the antistatic agent is provided, and the conveyance suppression unit (45) conveys toward the discharge port (17). A transport force in the direction opposite to the transport direction of the transport promotion unit (20) is applied to the antistatic agent that has been used. Thus, the antistatic agent conveyed in the direction of the discharge port (17) is pushed back before the discharge port (17), so that the antistatic agent is extremely biased near the discharge port (17). As a result of staying, a situation where the discharge port (17) is blocked is prevented.

  Therefore, it becomes possible to always discharge a stable amount of the antistatic agent from the discharge port (17) and put it into the game ball lifting and polishing apparatus (1) side. In addition, since a conveyance suppression part (45) is provided in the near side (final stage of conveyance) of the discharge port (17), the antistatic agent conveyed in the direction of the discharge port (17) by the conveyance promotion part (20). The conveyance force is not excessively hindered.

  According to the antistatic agent charging device (10) described in [2] above, the conveyance promoting portion (20) rotates around an axis extending in the longitudinal direction toward the discharge port (17), The start end (21) side and the end end (22) side, which are both ends of the conveyance promoting portion (20), can be handled in a state of being attached to the cap. The starting end (21) side of the conveyance promoting section (20) is attached to a drive side cap (30) connected to the motor (19) so as to be able to transmit power, and the terminal end (22) side of the conveyance promoting section (20) is It is rotatably supported at a position facing the discharge port (17) and attached to the driven side cap (40).

  As a result, the conveyance promoting section (20), the driving side cap (30), and the driven side cap (40) are integrally rotated and reliably driven by the motor (19) via the driving side cap (30). In particular, since the driven cap (40) is provided with the conveyance suppressing part (45), not only the conveyance of the antistatic agent but also the suppression can be realized simultaneously by driving one motor (19).

  According to the antistatic agent charging device (10) described in [3] above, the conveyance promoting unit (20) has both ends in place between the driving side cap (30) and the driven side cap (40). Supported. Thereby, even if the conveyance promotion part (20) is a member that can be expanded and contracted, such as a coil spring, the entire length does not change due to unnecessary expansion and contraction during rotation, and the conveyance promotion efficiency becomes unstable. It is possible to prevent elastic breakage due to unnecessary elongation.

  In particular, the end (22) side of the conveyance promoting part (20) attached to the driven side cap (40) is extended to a position facing the discharge port (17) downward and supported at the fixed position. Therefore, there is no situation where the terminal end (22) side of the conveyance promoting portion (20) is shifted to the driving side from the position facing the discharge port (17), and the antistatic agent is not easily discharged from the discharge port (17). The discharge amount of the antistatic agent from the discharge port (17) can be kept stable.

  According to the antistatic agent charging device (10) described in [4] above, the drive side cap (30) and the driven side cap (40) are integrally connected by the shaft (34) extending therebetween. Thereby, the rotational force of the drive side cap (30) by the motor (19) is reliably transmitted to the driven side cap (40) through the shaft (34), and the conveyance promoting portion is provided by the presence of the shaft (34). Twist and deformation in the middle part of (20) are also prevented, and reliable transport of the antistatic agent by stable rotation of the transport promoting part (20) can be realized.

  According to the antistatic agent charging device (10) described in [5] above, the conveyance suppressing portion (45) is centered on the rear end side of the shaft (34) connected to the driven side cap (40). Each is composed of a plurality of blades (46) that spread in the radial direction and are curved in an arc-shaped cross section in the rotational direction. Here, each blade (46) extends in parallel with the axial direction of the shaft (34) from the end face of the driven cap (40).

  Therefore, each blade | wing (46) which is a conveyance suppression part (45) can be shape | molded integrally with a driven side cap (40). With the blade (46) having such a simple structure, the antistatic agent solidified (or containing much moisture) on the front side of the discharge port (17) can be efficiently stirred and broken.

  Moreover, the inner periphery which opposes the outer periphery of the shaft (34) of each blade | wing (46) is arrange | positioned in the state which left the clearance gap between the outer periphery of the shaft (34). Thus, by providing a gap between each blade (46) and the shaft (34) of the conveyance suppressing unit (45), it is possible to reduce the resistance when the antistatic agent is stirred by each blade (46). .

  In addition, as the shaft (34) and each blade (46) rotate, the antistatic agent is picked up inside the blade (46) having an arc-shaped cross section and falls downward to the next blade (46). The situation of being picked up is repeated, and a transport force in a direction opposite to the transport direction of the transport promotion unit (20) is applied around the space formed by providing the gap.

  Thereby, the conveyance of the antistatic agent conveyed toward the discharge port (17) by the conveyance promotion unit (20) is suppressed, and the antistatic agent stays in an extremely biased state near the discharge port (17). The situation that the discharge port (17) is blocked is prevented, and it becomes possible to always discharge a stable amount of the antistatic agent.

  According to the antistatic agent charging device (10) described in [6], the conveyance promoting portion (20) is formed of a coil spring and can be simply configured. The coil spring is rotationally driven in the screwing direction. Then, the antistatic agent enters between the pitches of the coil springs, and the antistatic agent is conveyed with the rotation of the coil springs.

  The driven cap (40) is provided with a mounting portion (40a) to be attached in a state in which the terminal end (22) side of the coil spring is externally fitted, and can be easily attached. Even when the coil spring is biased, the pitch interval on the terminal end (22) side of the coil spring at the position facing the discharge port (17) is always held at a constant interval by the interval holding portion (44). It is possible to prevent the pitch interval of the springs from being eliminated (extremely narrow) and the antistatic agent from being hardly discharged from the discharge port (17).

  According to the antistatic agent charging device (10) described in [7], the antistatic agent reservoir (11) includes a bottom surface (12) having a semicircular cross section close to the outer periphery of the lower half of the coil spring. A lid (13) provided with a ceiling surface (13a) close to the outer periphery of the upper half on the terminal end (22) side of the coil spring was disposed above the discharge port (17). As a result, the end (22) side of the coil spring above the discharge port (17) is surrounded by an inner wall having a shape matching from above and below, and is attached to the outer peripheral side of the coil spring and the driven cap (40). The antistatic agent can be efficiently pushed out toward the discharge port (17).

  According to the antistatic agent charging device according to the present invention, when the powdered antistatic agent is charged into the game ball lifting and polishing device, the antistatic agent promoted to be conveyed in the direction of the discharge port is pushed back before the discharge port. Therefore, even if the antistatic agent has a property of being easily solidified, a stable amount of the antistatic agent can be discharged without remaining in the vicinity of the discharge port.

The game balls are distributed to the replenishment bowl from both sides of the upper tank 6, and the abrasive grains are collected in the circulation section 8 through the abrasive grain return passages 7 connected to the lower sides of the upper tank 6. Connected to the upper end side of the circulation part 8 is a tip of a dust induction hose 9 for guiding dust separated from the abrasive grains to the dust collector 9a.

Next, the operation of the antistatic agent charging device 10 will be described.
In FIG. 20, when an antistatic agent is charged into the game ball lifting and polishing device 1, an antistatic agent charging device 10 is attached to the ball collecting unit 2, and an appropriate amount of antistatic agent is added to the antistatic agent storage unit 11. Store. Here, the conveyance promoting unit 20 may be attached by screwing the fixed bracket 12a to the ball collecting unit 2 side. By opening the opening / closing plate 15 in the lid 13 of the antistatic agent charging device 10, the antistatic agent can be put into the antistatic agent reservoir 11 from the receiving port 14.

  The antistatic agent charging device 10 is driven by supplying power to the electric motor 19, and the power supply is controlled by a control unit (not shown) according to a predetermined program. Specifically, for example, if the timer is set to operate once a week and the rotation speed of the electric motor 19 per rotation is 1 rpm and the rotation time is 8 minutes, the game ball lifting and polishing apparatus 1 On the other hand, about 1 g of antistatic agent is slowly added. As described above, according to the antistatic agent charging device 10, an appropriate amount of the antistatic agent can be automatically and surely charged into the game ball lifting and polishing device 1.

  In FIG. 1, when the electric motor 19 is driven in a state where the antistatic agent is stored in the antistatic agent storage unit 11, the rotational force is decelerated and transmitted to the drive side cap 30, and the coil spring serving as the conveyance promoting unit 20. Rotates. Here, the coil spring is rotationally driven in the screwing direction, the antistatic agent enters between the pitches, and is conveyed to the discharge port 17 as the coil spring rotates. In particular, since the bottom surface portion 12 on which the conveyance promoting portion 20 is arranged has a semicircular cross section and is close to the lower half of the outer periphery of the coil spring, the antistatic agent on the bottom surface portion 12 is between the pitches of the coil springs. Conveying efficiency is improved.

  Simultaneously with the rotation of the conveyance promoting unit 20, the driven side cap 40 connected to the driving side cap 30 via the shaft 34 is also rotationally driven integrally. The driven cap 40 is provided with a conveyance suppressing part 45 so as to be positioned on the front side of the discharge port 17, and the antistatic that has been conveyed toward the discharge port 17 by the rotational drive of the conveyance suppressing unit 45. A transport force in the direction opposite to the transport direction of the transport promotion unit 20 is applied to the agent.

  As a result, since the antistatic agent is pushed back before the discharge port 17, a situation in which the antistatic agent stays in an extremely biased state in the vicinity of the discharge port 17, resulting in a situation where the discharge port 17 is blocked is prevented. The Without the conveyance suppressing unit 45, the antistatic agent may gradually stay above the upper end of the outer diameter of the coil spring from near the driven cap 40, and the stay may remain solidified. However, since the antistatic agent is pushed back by the conveyance suppressing unit 45, a situation where the antistatic agent is hardened can be prevented in advance.

  Specifically, as shown in FIG. 19, the conveyance suppressing portion 45 spreads in the radial direction around the rear end side of the shaft 34 connected to the driven side cap 40 and is curved in an arc-shaped cross section in the rotational direction. It consists of a plurality of blades 46. Here, each blade 46 extends in parallel with the axial direction of the shaft 34 from the inner end surface of the driven side cap 40, and the inner peripheral edge 46 a facing the outer periphery of the shaft 34 of each blade 46 has an outer periphery of the shaft 34. It is arranged with a gap in between.

  Thus, by providing a gap between each blade 46 and the shaft 34, the resistance when the antistatic agent is stirred by each blade 46 can be reduced. Then, as each blade 46 rotates, the antistatic agent is picked up inside the blade 46 having an arc-shaped cross section, falls downward through the gap, and is further picked up by the next blade 46. It is. As a result, a transport force in a direction opposite to the transport direction of the transport promotion unit 20 is applied around the space formed by providing the gap.

  Therefore, it becomes possible to always discharge a stable amount of the antistatic agent from the discharge port 17 and put it into the game ball lifting and polishing apparatus 1. Since the conveyance suppressing unit 45 is provided on the near side (final stage of conveyance) of the discharge port 17, it does not excessively inhibit the conveyance force of the antistatic agent conveyed in the direction of the discharge port 17 by the conveyance promotion unit 20. . Further, since the conveyance suppressing unit 45 is provided integrally with the driven side cap 40, not only the conveyance of the antistatic agent but also the suppression can be realized at the same time by driving one electric motor 19, and the configuration is simplified. can do.

  Further, as shown in FIG. 1, both ends of the transport promoting unit 20 are supported at fixed positions between the driving side cap 30 and the driven side cap 40. Thereby, even if it is a member which can be expanded and contracted like a coil spring which is the conveyance promoting unit 20, it does not expand and contract unnecessarily at the time of rotation, and the conveyance promotion efficiency becomes unstable or unnecessary. It is possible to prevent elastic breakage due to elongation.

  In particular, the terminal end 22 side of the conveyance promoting unit 20 attached to the driven side cap 40 is extended to a position facing the discharge port 17 downward and supported at the fixed position. Therefore, there is no situation where the terminal 22 side of the conveyance promoting unit 20 is shifted to the driving side from the position facing the discharge port 17, and the antistatic agent is not easily discharged from the discharge port 17. Can be kept stable. Further, as shown in FIG. 2, an arc-shaped protrusion 48 for preventing surface contact is provided on the outer end surface of the driven cap 40 that is in sliding contact with the inner side of the rear end surface 18 of the case body 10a. Thereby, the sliding resistance at the time of rotation of the driven side cap 40 can be reduced.

  Further, since the driving side cap 30 and the driven side cap 40 are integrally connected by the shaft 34 extending therebetween, the rotational force of the driving side cap 30 by the electric motor 19 is driven via the shaft 34. Is transmitted reliably. In addition, the presence of the shaft 34 prevents twisting and deformation at an intermediate portion of the conveyance promoting unit 20, and reliable conveyance of the antistatic agent by stable rotation of the conveyance promoting unit 20 can be realized.

  Here, the shaft 34 is set to have an outer diameter dimension that is not bulky even if it is inserted into the conveyance promoting unit 20, and erodes the storage / conveying space of the antistatic agent in the bottom surface portion 12 including the inside of the conveyance promoting unit 20. do not do. Further, when the antistatic agent scraped up to the upper periphery of the coil spring falls along with the rotation of the conveyance promoting unit 20, it collides with the shaft 34 and is diffused. Thereby, even an antistatic agent having a property of being easily solidified can be conveyed in a powder state until the end.

  In addition, the end 22 side of the conveyance promoting unit 20 is attached in a state of being externally fitted to the mounting part 40a of the driven side cap 40, but even if the conveyance promoting unit 20 is urged at the part, the discharge port 17 is provided. The pitch interval of the coil springs on the terminal end 22 side of the conveyance promoting unit 20 at the position facing the surface is always held at a constant interval by the interval holding unit 44. Thereby, it is possible to prevent the pitch interval of the coil springs that are the conveyance promoting unit 20 from becoming extremely narrow, and the antistatic agent from being hardly discharged from the discharge port 17. In addition, the space | interval holding | maintenance part 44 can be easily comprised with one small screw.

  Furthermore, as described above, the antistatic agent storage unit 11 includes a bottom surface of a semicircular cross section that is close to the outer periphery of the lower half of the coil spring that is the conveyance promoting unit 20. On the outer periphery of the upper half on the end 22 side, the ceiling surface portion 13a in the lid 13 is close. As a result, as shown in FIG. 9, the end 22 side of the conveyance promoting unit 20 above the discharge port 17 is surrounded by the inner wall having a shape that matches from above and below, and the conveyance promoting unit 20 and the driven cap 40 The antistatic agent adhering to the outer peripheral side can be efficiently pushed out toward the discharge port 17. The case body 10a including the lid 13 is made of a transparent material, and can be easily maintained and inspected.

  In FIG. 20, the game ball lifting and polishing apparatus 1 collects the game balls from the ball collection unit 2, and is then introduced from the abrasive particles stored in the abrasive storage unit 3 and the above-described antistatic agent input device 10. The antistatic agent is mixed and sent to the lower part of the lifting unit 5 through the transfer pipe 4. Then, the game ball and the abrasive grains are lifted and agitated in the pumping unit 5 to polish the game ball in the meantime. The polished game balls are separated from the abrasive grains by the separation mechanism in the upper tank 6 and then supplied to each game machine. Since such a game ball is not charged, there is no possibility of generating electrostatic induction noise without being discharged in a game machine or the like.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention can be modified or added without departing from the scope of the present invention. Included in the invention. For example, the conveyance promoting unit 20 can be replaced with a screw in addition to the coil spring.
