Definitions
- a spray washing device At one end of the booth and beyond an end wall thereof, is a spray washing device and a door through said end wall establishes communication between the washing apparatus and the interior of the booth so that the articles, after having been cleansed by the washing apparatus, can be passed through the door to reach the work bench.
- an outlet opening In an opposite end wall of the booth is provided an outlet opening and the wrapped or packaged articles can be passed out through this opening or else deposited into a shipping container entered through said opening.
- This invention relates to a method and apparatus for cleaning and packaging articles, such as machine parts and instruments and wherein the machine parts or instruments are adequately cleaned and packaged for encasement in a shipping container for subsequent transmittal to a point of use.
- the invention contemplates a booth open upon one I side, having a work bench that constitutes an assembly area for hardware or other instruments and with the booth constituting a clean work area that is provided with filters and blowers that direct a current of filtered air over the work area and with a cleaning machine attached to one end of the booth or a controlled area for initially cleaning the hardware or other objects by a liquid, and with a door between the cleaning device and the work area to permit the removal of the hardware from the cleaner to the work area and a discharge door at the opposite end of the booth or controlled area for disposal into a shipping container of a hardware package for subsequent removal.
- FIGURE 1 is a perspective view of an apparatus embodying the invention
- FIGURE 2 is a horizontal section taken substantially on line 2-2 of FIGURE 1, and
- FIGURE 3 is a transverse section taken substantially on line 3-3 of FIGURE 1.
- a pass-through cleaning device that embodies a booth 5, having a rear wall 6, a top 7 and end walls 8.
- the booth 5 is partitioned from its rear wall 6 as indicated at 9, and supports filters 10 of any desirable construction.
- a work bench 11 of convenient height is connected to the partition 9 and below the work bench 11 there has been provided an inlet filter 12, communicating with the blower 13 of any desirable construction, that is 3,354,495 Patented Nov. 28, 1967 driven from a motor 14 and whereby air is drawn through the filter 12 upwardly and through the filters 10 to flow over the bench 11 and to impinge upon and thoroughly remove any foreign particles from the article to be cleaned.
- One end 8 of the booth is provided with an inlet door 15, that is inwardly opening, as shown in dotted lines in FIGURE 2 and arranged over the door opening for the door 15 is a washing apparatus, indicated as a whole by the numeral 16.
- the washing apparatus 16 has communication through the door opening to permit articles to be passed from the washer onto the work bench 11.
- the washing device 16 is provided with a sliding door 17 to facilitate the placement of articles to be cleaned into the washer for subsequent removal through the door 15.
- the washing device 16 is similar to that shown in Patents 2,827,064 and 2,947,312 and comprises either movable or stationary racks over which the washing apparatus travels and with the washing apparatus projecting jets of sonic cleaning fluid both upwardly and downwardly over the articles to be cleaned.
- any suitable washing apparatus may be employed.
- the hardware or other instruments to be cleaned are first placed within the washing apparatus 16 where they are cleaned 'by sonic resonance of a liquid from any environment where contamination may have previously occurred. After the instrument or parts thereof are thoroughly cleaned, they are removed from the washing apparatus 16 by passage through the door 15 where they are placed upon the work bench 11 having an environment where less possibility of contamination is likely.
- the operator assembles the hardware, if it is in separate parts upon the work bench and places it into a hardware container, all in the presence of the flow of filtered air from the blower 13 creating a work area that is substantially free of contamination.
- the hardware container has been indicated in dotted lines at 20 and will be further disclosed in another application for patent. After the article has been placed free of contamination into the hardware container, it is attached to a shipping container 19 that has been fixed over the door opening 18.
- the system is simple, cheap to manufacture and highly effective to maintain a pass-through cleaning arrangement for permitting the hardware, after leaving the washing apparatus to be checked, assembled etc. in the clean work area defined by the walls of the booth and the flow of filtered air across the bench 11 during such assembly.
- a pass-through cleaning system comprising a booth open at one side, said booth having two spaced end walls, a top wall, and a rear wall opposite the open side; a partition within the booth connected to the top wall and end walls having dimensions congruent with the rear wall and being spaced forwardly thereof but rearwardly of the open side; a work bench within the booth having a substantially horizontal table member in elevated position engaging each of said partition and end walls and extending forwardly of the partition a distance short of the open side, the rearward edge portion of the table member engaging the entire length of the partition and the side edge portions of the table member engaging the end walls from the juncture of the end walls with the partition along a length of the end walls in the direction of forward extension of the table member; the area of the partition above the table member 'being substantially entirely composed of an air filtering surface and constituting an air outlet from the space between the rear wall and the partition and the area of the partition below the table member having an air filtering surface constituting an air inlet to the space between the rear wall and the partition; an air
