Abstract
In a glass washing machine having a glass carrier rotatable on an upright axis, half of the carrier is always in an access zone where glasses can be loaded onto the carrier and removed from it, the other half in a cleansing zone where detergent solution is discharged from a first set of spray nozzles and germicidal rinsing solution is discharged from a second set of nozzles. Upon actuation of a pushbutton switch, the carrier rotates through 180.degree., always in the same direction, then stops until the switch is again actuatd. Liquids are discharged from all nozzles while the carrier rotates. Detergent solution is recirculated, but fresh detergent solution is introduced during a predetermined portion of each period of carrier rotation.
Claims6
A machine for washing articles such as beverage glasses, comprising stationary structure that defines an access zone where articles can be loaded into and unloaded from the machine and a cleansing zone wherein there are a plurality of nozzles from which cleansing liquids are discharged against articles to be washed, a carrier rotatable about a fixed upright axis and whereon articles to be washed can be carried at locations all around said axis for orbital transport from said access zone through said cleansing zone and back to the access zone, electrically energizable drive means on said fixed structure for rotating said carrier in one direction and for causing cleansing liquids to be discharged from said nozzles, a tank wherein liquid discharged from certain of said nozzles is collected and from which that liquid is withdrawn and fed back to said certain nozzles for redischarge from them, and electrically energizable makeup means for delivering fresh liquid into said tank, said machine being characterized by:
- A. said zones being on opposite sides of a plane that contains said axis so that substantially one half of the carrier is in each of said zones;
- B. circuit closing means comprising a manually actuatable switch, said circuit closing means being connectable with an electric current source and connected with said drive means for initiating and maintaining energization of said drive means upon actuation of said manually actuatable switch;
- C. circuit opening means connected with said circuit closing means and with said drive means and responsive to the position of rotation of the carrier to terminate energization of said drive means each time the carrier has rotated through 180.degree. following actuation of said manually actuatable switch, said circuit opening means comprising
- (1) a cam constrained to rotation in unison with rotation of the carrier and
- (2) cam actuated switch means having two alternative conditions and cooperating with said cam to be converted thereby from one to the other of said conditions each time the carrier completes 180.degree. of its rotation following actuation of said manually actuatable switch;
- D. said cam being arranged to maintain said cam actuated switch means in said other of its conditions while the carrier rotates through a predetermined angle, substantially less than 180.degree., following each actuation of said manually actuatable switch;
- and
- E. said cam actuated switch means having connections with said manually actuatable switch and with said makeup means that provide for energization of said makeup means in consequence of the manually actuatable switch being actuated and while said cam actuated switch means is thereafter in said other of its conditions.
A machine for washing articles such as beverage glasses, comprising stationary structure that defines an access zone where articles can be loaded into and unloaded from the machine and a cleansing zone wherein there are a plurality of nozzles from which cleansing liquids are discharged against articles to be washed, said stationary structure comprising a tank in which liquid discharged from certain of said nozzles is collected and from which such liquid is fed back to said certain nozzles for redischarge from them, a carrier rotatable about a fixed upright axis and whereon articles to be washed can be carried at locations all around said axis for orbital transport by the carrier from said access zone through said cleansing zone and back to the access zone, electrically energizable drive means on said fixed structure for rotating the carrier in one direction and for causing cleansing liquids to be discharged from said nozzles, and electrically energizable makeup means for delivering fresh liquid into said tank, said machine being characterized by:
- A. said zones being on opposite sides of a plane that contains said axis;
- B. circuit closing means connectable with an electric current source and connected with said drive means, said circuit closing means comprising
- (1) a manually actuatable switch for initiating energization of said drive means and
- (2) means for continuing energization of said drive means following actuation of said manually actuatable switch;
- C. circuit opening means connected with said circuit closing means and with said drive means and arranged to terminate energization of the drive means whenever rotation of the carrier has brought it to either of a pair of predetermined positions of its rotation that are 180.degree. apart;
- and
- D. said makeup means having connections with said circuit closing means and said circuit opening means whereby the makeup means is energized during a predetermined portion of each period of energization of said drive means that is initiated by an actuation of said manually actuatable switch and terminates when the carrier arrives at one of said positions of its rotation.
A machine for washing articles such as beverage glasses, comprising stationary structure that defines an access zone where articles can be loaded into and unloaded from the machine and a cleansing zone wherein there are a plurality of nozzles from which cleansing liquids are discharged against articles to be washed, a carrier rotatable about a fixed upright axis and whereon articles to be washed can be carried at locations all around said axis for orbital transport from the access zone through the cleansing zone and back to the access zone, electrically energizable drive means on said fixed structure for rotating said carrier in one direction and for causing cleansing liquids to be discharged from said nozzles, a tank wherein liquid discharged from certain of said nozzles is collected and from which that liquid is withdrawn and fed back to said certain nozzles for redischarge from them, and electrically energizable makeup means for delivering fresh liquid into said tank, said machine being characterized by:
- A. said zones being on opposite sides of a plane that contains said axis, so that substantially one half of the carrier is in each of said zones;
- B. means for terminating energization of said drive means when the carrier arrives at each of a pair of predetermined positions of its rotation that are 180.degree. apart;
- C. means comprising a manually actuatable switch connectable with an electric current source and connected with said drive means for manually initiating energization of the drive means when the carrier is in each of its said positions of rotation and for maintaining such energization until the carrier arrives at the other of its said positions of rotation, so that the half of the carrier that is in the access zone when said switch is actuated will be in the cleansing zone when the carrier next stops;
- and
- D. means for energizing said makeup means during a fractional part of each period of energization of said drive means that begins with actuation of said manually actuatable switch and ends when the carrier next thereafter arrives at one of its said positions of rotation.
