When the freshly made cans come off the production line, they are open-ended so that they can be filled, after which the end of the can is placed on the open end and closed. Before such cans can be filled, they must be thoroughly cleaned and coated to remove any contamination left by the manufacturing work. Careful cleaning has always been a problem, and probably the best solution to date has been the device disclosed with its claims in U.S. Patent No. 3,353,515 to Stollen and Kaminski, issued November 21, 1967. The machine of this patent did a good job of handling the cans, but it was very large taking up a lot of floor space and was very expensive in relation to the number of cans processed per minute.

The present invention has developed a substantially smaller machine, which is also much cheaper, but which gives all the advantageous results of the patented device with an increasing number of cans per minute.

The invention comprises an apparatus comprising a pipe, an endless cable passing through the pipe and a plurality of can holders attached to the cable for conveying cans through the pipe with the opening facing downwards, the part of the pipe located on the cable support side forming a treatment chamber and a pipe on the other side of the pipe. the part forming a discharge part for a liquid, the supports being made in the form of a half-cylinder of a diameter which provides a clearance around the outer side of the cans to be treated, and the supports have a discharge opening substantially in the middle of the connection to the discharge part, the first set of nozzles being adapted to disperse the liquid outside the walls of the jars and another set of nozzles is adapted to throw the liquid upwards inside the jars.

The invention is characterized in that the third set of nozzles is adapted to eject liquid downwards towards the top of the jars, whereby the force of the liquid ejected upwards by the second set of nozzles is sufficient to balance the ejection force of the third set of nozzles. supported in their axial position, so that the flow of liquid around both sides of each can causes the entire surface of each can to be completely and evenly treated.

Of the several figures of the accompanying drawing: Fig. 1 shows a schematic plan view of a can holder showing the relationship between fluid flow and the can holder of the present invention to a transport cable; Figure 2 shows a schematic vertical sectional view of the same subject; Figure 3 shows a slightly schematic vertical sectional view of a device according to the invention; Fig. 4 shows a slightly schematic bottom view thereof; and Figure 5 shows a detailed cross-sectional view taken along line 5-5 of Figure 3.

The biggest problem with a can handling device is to ensure that the handling agent reaches all surfaces of the can uniformly and completely. The reference arm begins with Figure 1.

Figure 1 schematically shows a new solution of the present invention for achieving the desired results. In this bottom view, the can 1 is inside the movable support 2. A movable bracket moves the can bypassing the spray head 3. The bases time s sa 2 have a clearance around the body of the can due to the protrusions 4 and a fluid outlet 5 at the rear. In an age situation, the shower from the nozzle 3 causes a flow of fluid around both sides of the can. The protrusions 4 keep the can in a balanced state in the middle of the support 2 and allow the fluid to flow around the can and into the outlet 5 according to the arrows. The emptying opening 5 allows the treatment substances to drain away so that they do not remain behind the can. The presence of these substances behind the can could stop any flow around the 58446 centralized can.

Figure 2 shows a schematic elevational view of the injection head 6, 6a and 6b, the bracket 2 and the transporting of the can 1. The injection head 6a are directed upward toward the open bottom of the container for treating the interior of the container by spraying up in the inner space. The jet from the nozzle 6a transfers the weight of the container and the pressure of the spray head 6b and lifts the can away from the bottom of the support until the top and front edge of the can contact the rail 7 · When the can 1 is lifted from the support into contact with the rail 7 The contact with the can is very small and is mainly point contact and low pressure, and the effect of the syringes 6, 6a and 6b is applied to the inside and outside of the can on all its surfaces.

Figures 3 and show a general arrangement of a can handling device according to the invention. The arrangement is preferably helical in the sense that in the preferred embodiment the helix comprises longitudinal dips connected by transverse dips, all at an angle to the horizontal. The helical path is formed by a cable 8 which moves in the housing 9 and at each corner of the device past a series of cable wheels indicated by the common number 18. The cable returns as shown by the broken line 8a in Fig. 3. The cans 1 are fed to the supports by a suitable can feeding mechanism (not shown) and go to the bottom of the conveyor according to the can of Fig. 3. At the upper end of the conveyor, the cans 1 are unloaded for further processing and the endless cable returns to the bottom drop according to line 8a. The cable wheel system is equipped with a suitable actuator 10.

The spray heads or nozzles located inside the shell 9 can be used to spray any desired fluid such as stock solution, rinse water, acid treatment solution, protective coating or hot air for drying or tempering. The first complete cycle of the coil is preferably a washing cycle in which detergent is sprayed, the first half of the second cycle is a rinsing cycle in which rinsing water is injected, the second half of the second cycle is preferably an acid treatment cycle in which acid is injected, and in the last cycle the first half may be rinsing or kar-out period.

Figure 5 shows the cable 8 passing through the pipe 9. At point 1 there is a can and at point 2 its support. The part of the housing or tube 9 indicated by the general number 11 is the treatment chamber and the part indicated by the general number 12 is the discharge chamber. The treating agent is supplied to the nozzles 6, 6a and 6b lines 13, 13a and 13b, and, as described above, processing fluid is completely inside the cans and the outer side and the portion of the material then passes out tyhjerinysosaan 6 through the drain holes 12. lyhjennysosa 12 is actually part of the housing 9 and the fluid discharges into section 12 as indicated by the arrows. The cans initially rest on the support strips 2a.

The point contact portions 14a, 14b prevent them from initially falling out of the canister 2. The jet coming from the nozzle 6a lifts the cans up against a rail 7 which touches the upper front edge of the can. It is obvious that since the can is lifted off the strips 2a and because the cable 8 moves the support through the chamber 9 and the upper front edge of the can is in contact with the rail 7, the can is rotated during movement so that all surfaces of the can, both inside and outside, are treated. completely and carefully.

It is obvious that it is possible to make many variations within the spirit of the invention and that the description is not intended to impose any limitation on the invention which is not expressly set out in the claims.
