Abstract
Abstract Apparatus is now provided for the contacting of articles with coating liquid such that there is provided increased through put of coated articles. Articles for coating, such as small metallic parts, are placed in a perforate, rotatable, typically wire basket and most often immersed in a tank containing a coating liquid. During this coating operation, an adjacent basket spaced apart from the first basket is discharging coated parts and subsequently taking on fresh parts for coating at a loading/unloading zone. Following this, and the coating of the parts in the first basket, the baskets are moved in a line, e.g., concurrently. The second basket with the fresh parts is moving to its own coating tank for parts coating while the first basket is moving to the zone for unloading coated parts and for loading of fresh uncoated parts. Thus essentially twice the production of coated parts can be produced in an efficient and economical manner. Furthermore the apparatus readily lends itself to ease in color change for coated parts.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
268 words
An improvement in coating equipment for applying a fluid coating composition to parts contained in a perforate, rotatable basket, wherein parts for coating are transported to a coating zone containing said basket and coated parts are removed from said basket and said coating zone, and wherein parts contained in said basket are in contact with coating fluid and the basket is rotated to provide intimate contact between parts and coating composition, with there being means for removing parts from said basket for further processing, the improvement in said equipment comprising; first and second coating baskets located in linear relationship to one another in a line extending from a first basket coating zone through a single basket loading/unloading zone to a second basket coating zone; line support elements for said baskets providing support and direction for said baskets moving back and forth from the loading/unloading zone to a coating zone; means for supplying parts to be coated to a basket while said basket is located at said basket loading/unloading zone; means for applying coating composition to parts contained in a basket when said basket is positioned at its coating zone; shuttle means cooperating with said line support elements for shuttling said baskets along said line of relationship from said loading/unloading zone to a coating zone, whereby a first basket is transported by said shuttle means to said loading/unloading zone from its coating zone while said second basket at such time is being shuttled from the loading/unloading zone to its coating zone; and means for removing coated parts from a basket while said basket is positioned at said loading/unloading zone.
Claim 2
Dependent Claim
268 words
An improvement in coating equipment for applying a fluid coating composition to parts contained in a perforate, rotatable basket, wherein parts for coating are transported to a coating zone containing said basket and coated parts are removed from said basket and said coating zone, and wherein parts contained in said basket are in contact with coating fluid and the basket is rotated to provide intimate contact between parts and coating composition, with there being means for removing parts from said basket for further processing, the improvement in said equipment comprising; first and second coating baskets located in linear relationship to one another in a line extending from a first basket coating zone through a single basket loading/unloading zone to a second basket coating zone; line support elements for said baskets providing support and direction for said baskets moving back and forth from the loading/unloading zone to a coating zone; means for supplying parts to be coated to a basket while said basket is located at said basket loading/unloading zone; means for applying coating composition to parts contained in a basket when said basket is positioned at its coating zone; shuttle means cooperating with said line support elements for shuttling said baskets along said line of relationship from said loading/unloading zone to a coating zone, whereby a first basket is transported by said shuttle means to said loading/unloading zone from its coating zone while said second basket at such time is being shuttled from the loading/unloading zone to its coating zone; and means for removing coated parts from a basket while said basket is positioned at said loading/unloading zone.
Claim 3
Dependent Claim
59 words
The improvement of claim 1 wherein the direction of supplying parts to a basket is in line with the direction of unloading coated parts from a basket thereby providing a general line of travel for said parts, and the linear relationship of said coating baskets is positioned at an angle transverse to said line of travel for said parts.
Claim 4
Dependent Claim
22 words
The improvement of claim 1, wherein said coating baskets are wire mesh baskets and said line support elements comprise a guide rail.
Claim 5
Dependent Claim
13 words
The improvement of claim 1, wherein said parts supplying means comprise a conveyer.
Claim 6
Dependent Claim
18 words
The improvement of claim 1, wherein said means for applying coating composition includes a tank containing coating liquid.
Claim 7
Dependent Claim
23 words
The improvement of claim 1, wherein said shuttle means comprises a chain connecting support means of each basket along said line support elements.
Claim 8
Dependent Claim
17 words
The improvement of claim 1, wherein said means for removing parts from a basket includes conveyer means.
Claim 9
Dependent Claim
245 words
The improvement in the method of applying a fluid coating composition to parts processed in coating equipment which includes a perforate, rotatable basket, where parts are loaded to a basket, the basket is contacted with coating composition and rotated therein to provide intimate contact between parts and coating composition, and coated parts are discharged from said basket, the improvement comprising; establishing a path of travel for said parts, which path includes a direction of movement for uncoated parts to be charged to a basket, as well as a direction of movement for coated parts discharging from a basket; providing a basket loading/unloading zone in said path of travel; establishing a line of travel for a first and second basket, which line intersects said parts path of travel at said loading/unloading zone and extends there through from a first basket coating zone to a second basket coating zone; supplying parts to be coated to a first basket at said loading/unloading zone while said second basket is located at its coating zone; shuttling the resulting loaded first basket from said loading/unloading zone along the basket line of travel to the first basket coating zone; while at the same time shuttling the second basket along the basket path of travel from its coating zone to the basket loading/unloading zone; and unloading said second basket at the loading/unloading zone, while subsequently loading same, and while at that time coating parts in said first basket located at its coating zone.
Claim 10
Dependent Claim
245 words
The improvement in the method of applying a fluid coating composition to parts processed in coating equipment which includes a perforate, rotatable basket, where parts are loaded to a basket, the basket is contacted with coating composition and rotated therein to provide intimate contact between parts and coating composition, and coated parts are discharged from said basket, the improvement comprising; establishing a path of travel for said parts, which path includes a direction of movement for uncoated parts to be charged to a basket, as well as a direction of movement for coated parts discharging from a basket; providing a basket loading/unloading zone in said path of travel; establishing a line of travel for a first and second basket, which line intersects said parts path of travel at said loading/unloading zone and extends there through from a first basket coating zone to a second basket coating zone; supplying parts to be coated to a first basket at said loading/unloading zone while said second basket is located at its coating zone; shuttling the resulting loaded first basket from said loading/unloading zone along the basket line of travel to the first basket coating zone; while at the same time shuttling the second basket along the basket path of travel from its coating zone to the basket loading/unloading zone; and unloading said second basket at the loading/unloading zone, while subsequently loading same, and while at that time coating parts in said first basket located at its coating zone.
