Plant for the treatment of flat radiators

The 'invention relates to a system for the treatment of flat Radiators made of sheet steel or of appropriately designed objects that has a conveyor on which the radiators are suspended and through which they are successively passed through a degreasing bath a rinsing tank ,, a phosphating tank and at least be passed through a container containing a dye "

In the previously known systems of this type, the to treating radiators in a series of such successively on a single transport chain, namely in suspended in the longitudinal direction or direction of movement of this chain. In order to use these known systems a sufficient

To achieve high production output, the transport chain must at a high rate of magnitude Move 3 to 4 m / min. This is the reason why difficulties in operating the known systems of this type. .....

First of all, the hanging is often heavy and space-consuming trained radiators on a relatively fast moving chain a dangerous and difficult. Work. Furthermore, the arrangement of the radiators suspended from the chain in their direction of movement requires a large capacity of the immovable container, which contains the dye to be applied, because of the required Length and the inclined formation of the zones of the same for the introduction and the Y / ie the removal of the radiators. In addition, is the surface exposed to the action of the air relative to the color in the container large, which gives rise to intense evaporation of the solvent of the dye. After all, they hang Speed of the chain and the removal of the radiator from the paint containers on the one hand and the thickness of the on the one hand Coats of paint applied to radiators on the other hand from each other so that it is necessary to add a drying oven to the container in which the paint is to be applied, to the drying process of the on the radiator

In addition, the known systems do not allow the phosphate to dye radiators in different colors, without the transition from one color to another causing stoppages and disturbances in the continuous port movement of the row of radiators.

The subject of the invention is a system for the initially identified Purpose, through their novel training the

above-mentioned difficulties and disadvantages avoided will.

The new system is primarily characterized by that the conveyor for the radiator consists of at least two to each other there are parallel chains between which the radiators in a transverse arrangement, based on the locomotion » direction represent chains that are simultaneous and with the same are moved at low speed, are caught

Torque, the chains move at one speed of between 5 and 60 cm / min, in the case of the treatment of Radiators of the common lyps ^ with such of about 20 -cm / 'rain. 2rots of this low 5esch; vindi? Keit der Fb'rder-

chain »enables the new system to treat the same number of radiators as a system of the known type _f explained above through which the radiators are felt at a speed of 3 m / min, but the length of the new system is only. one fifth of that of a known system *

According to a special further feature of the invention the container containing the dye in programmed Way, regardless of the movement of the chains, alternately in the vertical direction between a lower position, in which each of the heating elements is located outside the container, and an upper position in which at least a radiator dips into the container, moves "

The loss of color that occurs during the removal of the radiator from the dye is special here low, because most of the color is due to the slow moving speed of the transport chains falls back into dpn container.

According to a further feature of the invention, the movement takes place of the dye container in the upward direction at a greater speed than its backward movement "in the downward direction Direction. This will create a

thin and regular layer of dye on top of the dye radiators leaving the container.

In order to keep its content of color above a minimum amount at all times, the dye container is connected to devices for supplying ύοά color, which come into effect as soon as the content of the container has dropped to this minimum amount ..

In all figures, the same elements are marked with the same reference symbols »

The system shown is for the treatment of flat radiators 1 determined from sheet steel. In other, for example, conceivable applications, it can also be used for treatment can be used by objects or bodies with a similar design.

The system has an elongated one, not shown Frame mounted on conveyor, through which the radiators 1 successively through different containers be conveyed through.

According to the illustrated embodiment, there is the conveyor from two parallel to each other and moving at the same speed chains 2 and 3, which over on each other parallel shafts 5 '' of which at least one is driven is running, seated sprockets 4. The drive and the transmission of the drive to the shafts 5 are shown in the figures not shown.

In other embodiments of the system according to the invention, the chains 2 φ.ά 3 can also be replaced by appropriate ropes.

The hot bodies 1 are each on the two chains 2 and 3 in the manner evident from Pig «3 successively in transverse direction see below the chains and especially at right angles to their direction of movement directional arrangement hung. You can use one or more or adjacent rows of sol-

The chains 2 and 3 run above three consecutive containers, including a degreasing container 6 _f He holds 8, in which the Phosphatieruxig of the flushed radiator 1 takes place.

The chains 2 and 3 run in a horizontal direction over awei successively arranged pigment containers 9 and 10, which are in the vertical direction in a purpose-designed part 11 of the frame under the action of τοπ pneumatic, hydraulic or oil pressure cylinders fe : i2h s'inä.

The paint containers 9 and 10 can be the same or from each other different colors included. They are mounted in movable frames 14 and 15 with lateral guide rollers 16 and 17 are equipped and, guided by this, lengthways vertical guide rails 18 and 19 of part 11 of the frame can be moved, on which also the pressure cylinder are attached.

The paint containers 9 and 10 are with the piston rods 20 and 21 of these pressure cylinders 12 and 13 connected so that the container and the piston rods can be moved upwards simultaneously and together.

These counterweights move on both sides of the frame each in to the direction of movement of the associated paint container opposite direction.

Each of the paint containers 9 or 10 is thus between a lower position in which the radiator 1 is outside of the container in question, and an upper position in which at least one heating element in the in the container

The speed of the movements of the paint containers 9 and 1C is independent of that of chains 2 and 3. Therefore, the speeds of these chains and this ink container are 9 and 10 each individually and optionally adjustable. The speed of the movement of the paint container is increasing seal larger than that in the downward direction.
