Description
SPECIFICATION
Improvements in Cleaning Equipment
The invention relates to cleaning equimpent and has been developed in relation to equipment for degreasing and claning gearboxes and other transmission components and housing elements.
The invention relates, in particular, to cleaning equipment of the kind comprising a chamber containing a support for articles to be cleaned, a reservoir for cleaning liquid, and pumping means for delivering cleaning liquid from the reservoir to pipe-work within the chamber, the pipework being apertured so that, in use, jets of cleaning liquid from the apertures are applied to articles supported within the chamber.
Normally, the degreasing and cleaning of engine components requires two separate operations requiring the use of two different liquids. First, the components are cleaned using a cleaning solution, for example a hot aqueous alkaline preparation, and then they must be rinsed using a rinsing solution which may, for example, include a rust inhibitor. Hitherto, the need to perform two separate operations using different solutions has meant that separate cleaning and rinsing apparatuses are required, each operating with a different solution. With such an arrangement it is necessary to remove the components from one apparatus, after cleaning, and transfer them to the other apparatus for rinsing. Not only is this time-consuming and inconvenient, but care must be taken when handling components washed in an alkaline solution.In addition, the necessity of providing two sets of apparatus increases capital and maintenance costs, as well as increasing the floor space taken up by the equipment. The present invention sets out to provide cleaning equipment in which both cleaning and rinsing operations, with different solutions, can be carried out in a single apparatus.
According to the invention there is provided cleaning equipment, of the kind referred to above, wherein there are provided two reservoirs for cleaning and rinsing liquids respectively, pump means for delivering liquid from each reservoir to said pipework, means for draining liquid from said chamber, and liquid flow control means for directing liquid drained from the chamber selectively to one or other of said reservoirs.
Thus, when an initial cleaning operation is required, the liquid flow control means are operated to direct liquid drained from the chamber back into the cleaning liquid reservoir, and the pump delivering liquid from that reservoir to the chamber is energised. When initial cleaning has been completed, the pump is de-energised and the chamber completely drained. The liquid flow control means are then operated to direct liquid drained from the chamber into the rinsing liquid reservoir. The pump delivering rinsing liquid from that reservoir is then energised and the rinsing operation is carried out. The components being cleaned remain in the chamber during both operations and no handling of them is required.
The means for draining liquid from the chamber may include an outlet passage in the lower part of the chamber, and said liquid flow control means may comprise an inclined duct which is adjustable between first and second positions where a lower end thereof is in communication with said reservoirs respectively.
The duct may be pivotally mounted for tilting movement about a horizontal axis intermediate its ends between first and second positions, so that in the first position one end of the duct is lowermost and in the second position the opposite end of the duct is lowermost, the aforesaid outlet passage being in communication with a part of the duct intermediate its ends, and the opposite ends of the duct being in communication with said reservoirs respectively.
Preferably the tilting duct comprises a channelshaped element the open side of which is uppermost and located beneath said outlet passage.
The reservoirs may each have an opening over at least a part of the top thereof, above the normal level of liquid in the reservoir. A filter tray may be mounted below each end of the duct and above the normal level of liquid in the reservoir.
The following is a more detailed description of one embodiment of the invention, reference being made to the accompanying drawings in which:
Figure 1 is a schematic front elevation of a component cleaning machine according to the invention, and
Figure 2 is a plan view of the machine.
The machine is generally in the form of an inverted "T" with two reservoirs 10 and 1 one containing a cleaning solution and the other a rinsing solution, being arranged on either side of the vertical leg of the "T" which comprises a washing chamber 12. The floor of the washing chamber is V-shaped and slopes downwardly towards the centre line of the chamber where there is formed an elongated sluice 1 3 providing an outlet passage from the chamber.
Associated with the reservoirs 10 and 11 are pumps 14 and 1 4a respectively, each of which delivers liquid from its associated reservoir to pipework 22 within the chamber 12, the pipework being apertured so that, in use, jets of liquid issuing from the apertures are applied to components supported within the chamber in a component carrier 1 5.
Mounted immediately beneath the sluice 13 is a channel-shaped shed plate 1 6 which is pivotally mounted for tilting movement about a horizontal axis 1 7 extending beneath and parallel to the sluice 13. The shed plate 16 is coupled to a reversible ciose-coupled worm reduction box and motor indicated at 18 in Figure 2.
Disposed over the reservoirs 10 and 11, and above the normal level of liquid therein, are located filter trays 1 9 and 20 respectively. The opposite ends of the shed plate 1 6 remote from its pivot axis 1 7 are disposed over the filter trays 19 and 20 respectively and, as may best be seen from Figure 2, the filter trays are slightly wider than the shed plate as viewed in plan. The shed plate is tiltable under the action of the gearbox and motor 18 between first and second inclined positions where the shed plate slopes downwardly towards one or other of the filter trays respectively.
In operation of the machine, the operator loads the components to be cleaned into the component carrier 1 5 and wheels the carrier into the washing chamber 12, securing the carrier within the chamber and closing the door 21 thereof. Initially the shed plate 1 6 is in the position shown in solid lines in Figure 1 where it is inclined downwardly towards the filter 1 9 disposed over the reservoir 10 containing the washing solution. The associated pump 14 is then activated and delivers the washing solution, which is heated, from the reservoir 10 to the apertured pipework 22 within the chamber 12.
The pipework may be of the kind comprising a looped spray bar rotatable with respect to the component carrier 1 5 and formed with tangentially directed apertures so that, in use, jets of the cleaning liquid issuing from the apertures are applied to the components within the chamber, and the spray bar is rotated under jet reaction.
The washing operation continues for a
predetermined period which is preset on an
adjustable cycle timer, not shown. During the
course of the washing operation the cleaning
liquid drains from the chamber 12 through the
sluice 13 and falls onto the shed plate 16 which
directs the drained liquid into the filter tray 19,
from where it passes, under gravity, back into the
reservoir 10.
When the cleaning operation has been
completed the pump 14 stops and a time lapse
occurs while any residue of cleaning liquid within
the chamber 12 is drained off and led back to the
reservoir 10 via the shed plate 1 6 and filter tray 19. The motor 18 is then activated to tilt the shed
plate 1 6 to a position where it is inclined
downwardly towards the filter tray 20 over the
rinsing solution reservoir 11.
The pump 1 4a associated with the rinsing
solution reservoir 11 is then activated to pump
rinsing solution from that reservoir to the
pipework 22 within the chamber 12, the liquid
draining from the chamber and being returned via
the shed plate 1 6 and filter tray 20 to the
reservoir 11. Again, the time of rinsing is
controlled by a preset cycle timer. When rinsing
has been completed the rinsing pump stops, and
there is again a time lapse to allow any residue of
rinsing liquid to drain from the chamber. The shed
plate is then activated by the motor 18 once more
so that it is again inclined downwardly towards
the washing solution reservoir 10 so that the
machine is ready to accept the next batch of dirty
components. The cleaned and rinsed components
may then be removed from the machine.
By arranging filter trays between the shed
plate and the reservoirs, it will be appreciated that
the condition of the filter trays will have no effect
on the operation of the associated pumps,
regardless of the condition of the filters. If a filter
tray becomes completely blocked, the drained
liquid will merely overflow the sides of the tray
and fall directly into the reservoir beneath. This is
in contrast with the arrangements used hitherto in
which filters have been located between the
outlet from the reservoir and the inlet to the
pump, or between the pump discharge outlet and
the pipework in the chamber 12. In such
arrangements such filters affected the operation
of the pump as they gradually became blocked with foregin matter.
The door 21 is hingedly mounted on the
machine for pivoting movement either about a vertical or about a horizontal axis. In an alternative
arrangement, two doors may be located on
opposite sides of the machine and a motorised
conveyor provided in the lower part of the
chamber 12 to convey components into and out of the chamber, the conveyor being indexed and timed to operate only when the doors are open.
A vapour extraction fan may be fitted to the
chamber. Where this is done it is so controlled that it is activated only after the rinse pump stops and for a predetermined period, which is set on a cycle timer. This prevents needless heat extraction from the machine which would otherwise occur if the fan were continuously
running.
The above described operations are preferably carried out automatically on a cycle timer, but they may also be effected manually. For example, instead of the shed plate 1 6 being motor driven, the operator may be provided with a locking lever connected to the shed plate so that he may pivot the shed plate to the correct position according to whether a washing or rinsing operation is required. In this cas limit switches are preferably located so that shouid the operator inadvertently have the shed plate inclined towards one reservoir while attempting to start the pump associated with the other reservoir, this will be over-ridden electrically.
