It has been.

  Next, a procedure for attaching the dust collection pack 30 to the vibration base 70 will be described with reference to the drawings.

  In FIG. 6, the paperboard 32 provided in the dust collection pack 30 is slid from the opening portion 43 side, supported by the rail portion 42, and attached to the detachable member 40. Next, the detachable member 40 is attached to one surface of the vibration base 70 from one surface side. At this time, the convex protrusion 41 formed on the detachable member 40 is fitted into the slit 75 formed on the vibration base 70, and the locking claw 71 formed on the vibration base 70 engages the edge of the detachable member 40. Stop. Further, the presser pawl 72 formed on the vibration base 70 closes a part of the opening 43 to prevent the paperboard 32 from being detached.

  The paperboard 32, the detachable member 40, and the vibration base 70 are each formed of a paperboard hole 32 a, a detachable member hole 40 a, and a vibration base hole 70 a formed at substantially the center, and It is aligned on the same axis and penetrates through the dust collection port 24.

  In this manner, the dust collection pack 30 can be attached to the vibration base 70 via the detachable member 40. Further, since the detachable member 40 and the vibration base 70 are detachable, the dust collection pack 20 can be easily removed and replaced by following this procedure in reverse.

  According to the dust collector 10 configured as described above, the dust removed from the game ball 2 is collected as follows. Here, since the air flow and the dust flow due to the intake air have the same path, each flow will be described together for easy understanding.

  1 and 2, when the dust collector 10 is operated, the suction compressor 60 constituting the dust collector 10 rotates the fan to start intake. Dust removed from the game ball 2 in the polishing / lifting pipe 4 is sucked into the negative pressure case 20 constituting the dust collector 10 from the dust collector inlet 7 via the dust collection hose 23. In FIG. 4, since the sucked dust is sucked by the suction compressor 60 from the inside to the outside of the dust collection pack 30 covered by the dust collection opening 24, the dust is filtered by the dust collection pack 30 and the inside intake opening. It adheres to the vicinity of 25 and only air passes through the dust collection pack 30. The passed air passes through the ventilation communication passage 85 of the suction compressor connection base 80 and is sucked from the suction port 61 of the suction compressor 60. Even if a small amount of dust passes through the dust collection pack 30, no dust enters the suction compressor 60 because the suction port 61 is provided with a disk-like sponge.

  In FIG. 4, the dust specifically adheres to the inside of the dust collection pack 30, particularly to the dust adhesion range 30 a. When the dust collection pack 30 is clogged with dust, the dust collection force is reduced. However, the dust collection pack 30 can be vibrated by operating the vibration device 50 to prevent the clogging. When the drive motor 51 is driven, the rotational motion is transmitted to the vibration conversion gear 54 via the drive gear 52 and the driven gear 53.

  In FIG. 5, the vibration base 70 is pulled clockwise around the dust collection port 24 by the restoring force of the coil spring 77 in the tension state. Further, since the outer periphery of the vibration converting gear 54 is in contact with the inner periphery of the vibration converting hole 74, the vibration base 70 is stopped against the restoring force. In this state, when the vibration converting gear 54 having the undulating portion 54 a formed on the circumference is rotated clockwise, the vibration base 70 is stepped with respect to the vibration converting gear 54 when the valley portion 54 b passes through the step portion 74 a. Since the portion 74a is instantaneously drawn toward the center of the vibration converting gear 54 along the trough portion 54b by the restoring force of the coil spring 77, the portion 74a is instantaneously tilted clockwise to the edge of the crest portion 54c (boundary with the trough portion 54b). Contact. When the vibration converting gear 54 further rotates and the crest 54c passes through the step 74a, the vibration base 70 has a step 74a that reaches the trough 54b along the crest 54c with respect to the vibration converting gear 54. Since it is slowly moved away from the center of the vibration converting gear 54, it is slowly tilted counterclockwise.

  When this operation is repeated, the vibration base 70 alternately repeats clockwise and counterclockwise rotation around the dust collection port 24 as a central axis. That is, the vibration base 70 tilts clockwise when the valley portion 54b passes through the stepped portion 74a, and returns to the original position by inclining counterclockwise until the valley portion 54b approaches again through the peak portion 54c. Then, the dust collection port 24 vibrates about the central axis.

  Specifically, the vibration converting gear 54 has a diameter of approximately 20 mm, and the vibration converting gear 54 is driven at 30 revolutions per minute by the drive motor 51 to bring the four undulating portions 54a into contact with the stepped portion 74a twice per second, The vibration base 70 is vibrated.

  The period and amplitude of vibration can be changed by the rotational speed of the drive motor 51, the size of the vibration conversion gear 54, the difference between the valley portion 54b and the peak portion 54c, and the like. Further, the vibration of the vibration base 70 may be in the axial direction in addition to the rotation around the dust collecting port 24 as long as the airtightness in the negative pressure case 20 is maintained. The structure for generating vibration is not limited to this embodiment, and for example, a vibration motor using eccentricity or an ultrasonic motor using piezoelectric elements may be used.

  When the dust collection pack 30 vibrates, the dust attached to the dust adhesion range 30a is shaken off and accumulated in the dust accumulation range 30b. The dust collection pack 30 continues to collect dust while maintaining the dust collection force without causing clogging because the dust is peeled from the dust adhesion range 30a.

  While the dust collection pack 30 is vibrating, that is, while the vibration device 50 is being driven, the suction compressor 60 is controlled to a predetermined schedule and stops the rotation of the fan.

  The vibration device 50 and the suction compressor 60 are controlled by, for example, a timer relay or a sequencer as a control unit, and operate and pause according to a preset schedule, such as when a predetermined time is reached or when a predetermined time has elapsed. Like that. For example, a schedule is set such that the suction compressor 60 is stopped every 6 hours for 1 minute, and the vibration device 50 is operated for 30 seconds. Furthermore, it is possible to control based on a signal from the pressure sensor 63. Note that manual control of turning on or off the switch is also possible. The control means may be provided in the hall computer.

  As described above, according to the polishing lift 1 according to the present embodiment, the dust collection pack 30 has the vibration base 70 by the stepped portion 74 a along the undulating portion 54 a of the vibration conversion gear 54 rotated by the drive motor 51. Vibrates and vibrates with the detachable member 40 mounted on the vibration base 70. With this configuration, the dust collection pack 30 is free from dust adhering to the inside and has good air permeability, and does not hinder intake by the suction compressor. Therefore, clogging of the dust collection pack 30 is prevented, the dust collection power is not reduced, and the replacement time of the dust collection pack 30 can be extended to about six months.

  The dust collection pack 30 is provided in the negative pressure case 20 so as to be detachable from the vibration base 70 by the detachable member 40. Therefore, the dust collection pack 30 filled with dust can be easily removed and replaced. Further, since the negative pressure case 20 is not contaminated by dust, labor for cleaning the negative pressure case can be saved.

  The negative pressure case 20 includes a negative pressure case main body 21 and a negative pressure case lid 22, which are detachable. Therefore, the negative pressure case main body 21 in which dust is accumulated can be removed from the negative pressure case lid 22. it can. Specifically, the locking portion 28 provided on the front side of the negative pressure case 20 is released, and the negative pressure case body 21 is slid sideways with respect to the negative pressure case lid 22 to thereby back the negative pressure case 20. Can be separated into a male side and a female side. Therefore, the dust collection pack 30 housed in the negative pressure case 20 can be easily replaced.

  The negative pressure case 20 is not limited to the configuration in which the negative pressure case main body 21 and the negative pressure case lid 22 are separated as in the present embodiment, but may be configured by providing a door as an inspection port on the front side. The door is provided with a seal rubber so as to maintain airtightness. With this configuration, the dust pack 30 can be replaced only by opening and closing the door. Therefore, the dust collection pack 30 can be replaced more easily.

  In the negative pressure case 20, a negative pressure case seal rubber 26 that fits the edge of the negative pressure case body 21 circulates around the edge of the negative pressure case lid 22, and a dust collection port seal rubber 92 is connected to the dust collection port 24. An inlet seal rubber 90 is provided and sealed. With this configuration, airtightness in the negative pressure case 20 is maintained. Therefore, the dust collecting power of the dust collector 10 can be increased.

  In the negative pressure case 20, a plurality of dust collection pack separating portions 21 a are formed so as to protrude inward from the side surface side and the bottom surface side. With this configuration, a gap is formed between the dust collection pack 30 swelled by dust collection and the inside of the side surface side and the bottom surface side of the negative pressure case main body 21, and the dust collection pack 30 is in close contact with the inside of the negative pressure case 20. There is nothing. Accordingly, when the suction compressor 60 is in operation, the dust collection pack 30 is likely to swell, the air permeability of the dust collection pack 30 can be ensured, and the dust collection force does not decrease.

  Operation and stop of the vibration device 50 and the suction compressor 60 are controlled according to a predetermined schedule, and the dust collection pack 30 is vibrated by vibration from the vibration device 50. With this configuration, dust adhering to the inside of the dust collection pack 30 is periodically peeled off, and good air permeability is always maintained. Therefore, the dust collection power of the dust collector 10 can be maintained, and the replacement time of the dust collection pack 30 can be prolonged.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
