FR2686532A1 - Vertical washing machine for industrial parts - Google Patents

Abstract

The invention relates to the manufacture of a vertical washing and drying machine of which the main advantage is that it requires little floor space, and yet the parts can be loaded and unloaded on a front work station. The machine thus designed may consist of a frame (12), a loading and unloading station (1), the parts to be treated being schematised by a rectangle (2), a parts conveyor (3), a degreasing bath (4), an ultrasound emitter for activating the degreasing process (5), an oil remover for regenerating the washing fluid (6), a draining station (7), a rinsing station (8), a drying tunnel (9), a drying fan (10) and a condenser for drying the air (11). Applicable to degreasing and drying machines, and more generally to surface-treating machines.

Description

 The present invention relates to a particular vertical construction method for a degreasing and drying machine for industrial parts.

 It is known that existing machines for degreasing and drying industrial parts require a large floor space and often require a civil engineering for their installation. For belt or tunnel machines, the parts are introduced from one end of the machine and the output at the other end, which implies the implementation of significant means for their automation. For machines with rotary tables or soaking baths, the relatively long cycle time for washing and drying implies low production.

As a general rule, and apart from basket machines or rotary tanks, the installations on the market do not allow the parts to be turned over during the treatment phases with the aim of emptying the detergent or waste which may be contained in cells or non-through holes.

 It is to these drawbacks that the present invention more specifically intends to remedy.

 The vertical construction method according to the invention is characterized in that it comprises means capable of automatically ensuring the presentation of a workpiece support for loading or unloading in the same place, soaking the workpiece for a sufficient time in a washing bath, rinsing of the part and drying in an appropriate tunnel, all of these operations being carried out on a particularly small floor space.

The appended drawings, given by way of example, will allow a better understanding of the invention, the characteristics which it presents, and the advantages which it is likely to provide:
-Fig. 1 is a schematic view of the parts conveyor, the washing bath, the rinsing station and the drying tunnel.

 -Fig. 2 is a front view of the machine and its loading station according to FIG. 1.

 The machine island (12) is shown in the figure, the loading and unloading station (1), the parts to be treated symbolized by a rectangle (2), the parts conveyor symbolized by an axis line (3), the degreasing bath. (4), the ultrasonic transmitter activating the degreasing (5), the oil separator for regenerating the detergent (6), the drip station (7), the rinsing station (8), the tunnel dryer (9), the drying turbine (10), and the air dryer-condenser (11).

 Figure 2 shows the front view of the machine with its loading station (1) and a part symbolized by a rectangle (2).

The work cycle with this material will therefore be as follows:
- Loading of the part to be treated (2) at the station (1) by an operator or a handling robot.

 - Conveyor feed (3) and soaking of the part in the degreasing bath (4).

 - Turning of the part by the movement of the conveyor.

 - Draining of the workpiece (7).

 - Rinsing by sprinkling of water in station (8).

 - Drying in the tunnel (9) with turning of the part.

 - Presentation of the part (2) at the unloading station (1).

 According to variants not illustrated, washing can take place by solvent, or by washing in a bath or by spraying, rinsing is not compulsory, the oil separator as well as the condenser - air dryer are optional equipment.

 By way of nonlimiting example, a machine allowing the washing and drying of foundry pieces of dimensions 300 mm x 200 mm x 600 mm with a production of 1 piece every 20 seconds will have a footprint of 900 mm x i 300 mm and a height of 3000 mm.

 It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.

Claims (3)

 1) Vertical construction method of a degreasing-drying machine, characterized in that it comprises means which ensure the movement of the parts to be treated (2) through a washing bath (4), of draining (7), a rinsing station (8), a drying tunnel (9) while benefiting from a reduced floor space.  2) Device according to claim 1, characterized in that the parts to be treated (2) are transported by a vertical conveyor (3) allowing loading and unloading at the same place (1).  3) Device according to claims 1 and 2, characterized in that the movement of the conveyor (3) allows the parts (2) to be turned over both during the washing phase in the bath (4) and during the drying in the tunnel (9 ).
