Static electricity and dust removing apparatus

Abstract

This static electricity and dust removing apparatus has a base box ( 11 ) provided with an airflow inlet port ( 16 ), and a processing head ( 23 ) attached to the base box ( 11 ) through a support column ( 21 ), wherein a processing space ( 24 ) is formed between the airflow inlet port ( 16 ) and the processing head ( 23 ). Air curtains for isolating the processing space ( 24 ) from the outside due to air from a spout of an air spout pipe ( 33 ) are formed at a front opening portion ( 29 ) and right and left side opening portions ( 28 ) of the apparatus. Ionized air generated by an ion generator ( 42 ) is spouted into the processing space ( 24 ), so that the ionized air is sprayed on matters to be processed which are disposed in the processing space ( 24 ) and dust is removed from the matters to be processed. Thereby, a static electricity and dust removing operation to the dust adhering to the matters to be processed can be efficiently performed within a short time, and work environment can be prevented from being contaminated due to a leakage of the removed dust.

1 . A static electricity and dust removing apparatus for spraying ionized air on a matter to be processed to remove dust adhering to the matter to be processed, the apparatus comprising:
 a base box having an airflow inlet port into which air flows and an airflow path for guiding a flow of air flowing from the airflow inlet port;   a processing head attached to a support column provided to the base box so as to face the airflow inlet port, a processing space being formed between the airflow inlet port and the processing head;   an air spout member provided to the processing head and provided with a spout for spouting air toward the airflow inlet port to form an air curtain for isolating the processing space from an outside; and   an ion spout nozzle provided to the processing head to spray the ionized air on the matter to be processed in the processing space.   
   
   
       2 . The static electricity and dust removing apparatus according to  claim 1 , wherein a front opening portion is formed between a tip portion of the processing head and a tip portion of the base box, the air curtain is formed along the front opening portion, and the matter to be processed is carried in and out the process space via the front opening portion. 
   
   
       3 . The static electricity and dust removing apparatus according to  claim 1 , wherein a front opening portion is formed between a tip portion of the processing head and a tip portion of the base box, side opening portions are formed between both side portions of the processing head and both side portions of the base box, the air curtain is formed along the front opening portion and each of the side opening portions, and the matter to be processed is carried in and out the process space via any of the front opening portion and each of the side opening portions. 
   
   
       4 . The static electricity and dust removing apparatus according to  claim 3 , wherein a removable cover is mounted on each of the side opening portions, and the matter to be processed is carried in and out the process space via the side opening portions by detaching the cover. 
   
   
       5 . The static electricity and dust removing apparatus according to  claim 1 , further comprising:
 a sensor for detecting the matter to be processed which is carried into the processing space; and   control means for performing, when the sensor detects that the matter to be processed has been carried in, processing start control of forming an airflow in the base box, spouting air from the air spout member, and spouting the ionized air from the ion spout nozzle in this order per lapse of a predetermined time.   
   
   
       6 . The static electricity and dust removing apparatus according to  claim 5 , wherein the control means performs, when the matter to be processed is carried out the process space, processing completion control of stopping spouting the ionized air, stopping spouting the air from the air spout member, and stopping forming the airflow in the base box in this order per lapse of the predetermined time. 
   
   
       7 . The static electricity and dust removing apparatus according to  claim 5 , wherein the control means performs, when a predetermined time lapses, processing completion control of stopping spouting the ionized air, stopping spouting the air from the air spout member, and stopping forming the airflow in the base box in this order per lapse of the predetermined time.
