Wide treatment machine

The invention relates to a wide-processing machine for j webs which are wound for treatment by liquid or gaseous media on a perforated cloth beam and are exposed in a treatment chamber rotating each process ¹ ·

Known machines have a hold and in the Hegel Transport device for the goods tree, which together; is retracted with the tree into the handling chamber and on which the goods tree remains during the treatment.

The disadvantage of these machines lies primarily in the complex chamber construction, which is used to introduce the The direction of transport can usually be designed so that it can be opened

209840/0764

must, in the complex construction of the transport device, which is largely exposed to the Sammer atmosphere, as well as the fact that such Due to the construction, chambers designed to be hinged open cannot under any circumstances be made leak-proof for higher pressures, so that the known principle is useless for high pressure or vacuum treatment processes

In addition, it is also known to view the goods tree To drive the transport trolley to the treatment chamber and by means of rollers on rails provided on the chamber wall to insert into the same; The main disadvantage of such machines is that they are expensive and geared towards stability To see constructions of the treatment chamber, which take over the entire weight of the tree Has. In addition, the tree of goods is not fixed in the bearing part, but only lies on the Rails on so that only low operating speeds can be achieved. !

The invention is based on the object of the.

To avoid i acquaintances, ie in particular a Breitbehand- '

management machine that with a much lower |

total constructive effort also, for high pressure, Solvent or vacuum treatment can be used «

209840/0764

According to the invention, this task is primarily solved that a self-supporting machine frame is provided on which the chamber is attached that on Machine frame two times reaching into the chamber from the outside Bearing points for receiving the tree of goods from the holding device and aur bilateral rotatable bearing the same are provided during the treatment, and that the drive device is fixedly arranged on the machine frame is and is in engagement with the respectively introduced tree of goods via at least one bearing point.

The design of a machine frame that supports both the chamber and the goods tree is most advantageous Way enables both the construction of much lighter and more simply constructed chambers, as well as any exchange of chambers for special processes, provided that - as proposed according to the invention - the connection between the chambers and the machine frame is designed to be releasable accordingly

The introduction of the tree of goods into the chamber is considerably simplified according to the invention if the holding device engages the same in a bearing point only on one side. It is particularly advantageous if for introduction of the goods tree in the ü-ammer a position of the machine frame as well as at least part of the assigned

209840/0764

Chamber wall can be folded away, with a quick and safe introduction in particular still thereby guaranteed can that a protective device on the machine frame to hold the tree in the period after the introduction, storage in a storage location and detachment from the Holding device, and is provided before folding back and engaging the second bearing point.

Another reduction in the amount needed for fabric treatment Devices can be achieved if the holding device is a movable carriage whose chassis extends under the goods tree and has a base on one side with a bracket attached to it, on which the tree of goods with a storage point can be attached so that the winding of the fabric to be treated, the transport to the Treatment chamber as well as the introduction into the chamber with the same Device can be achieved. However, it should be emphasized that - in contrast to known ones, in the treatment chamber mobile car - after the goods tree has been brought into the chamber of the car again, for example for the next winding process is available, making it the most economical Use of the resources is guaranteed.

The introduction is particularly facilitated by the fact that the support arm and bearing points on the machine frame in

209840 / Ü784

are arranged at the same height, and that the machine frame has ground clearance in the area under the chamber in such a way that for introducing the freely cantilevered tree of goods in the opened chamber the part of the chassis protruding under the tree under the chamber or the machine frame is slidable.

According to the invention, it is also provided that a specially designed holding device is used as a holding device for transporting the tree Provide crane hook.

The angling of the crane hook over the tree is chosen so that the suspension point of the hook itself from Torques is kept free.

But it has now been shown that the crane to be transported wound trees are usually not exactly evenly, that is, are wound symmetrically, so that the suspension point in this way due to various large torques

is burdened that the horizontal position of the tree can not be maintained exactly.

These deviations - depending on the direction in which they are present - cause difficulties when attaching the Goods construction a on the storage point in the chamber or when pulling it from the crane hook with it, so that constantly with operational ·) · disruptions are expected or monitoring

209840/0764

personnel must be deployed »

It is therefore also used to automatically comply with the desired Floating position of the Warehbaum proposed that a position sensor for determining the floating position on the crane hook of the goods tree is provided that a motor adjustable tare weight is also arranged on the crane hook is, and that the position sensor for activating the motor and proportional shifting of the taring weight in the case of asymmetrical Load of the crane hook is functionally coupled to the engine. The motor can be any Drive direction, such as an electric motor or a pneumatic device.

As a position sensor, for example, a switch, which is preferably under the influence of gravity in certain situations by activating the motor the displacement of the l'ararian weight until reaching the desired change of position of the goods tree caused, be provided. Preferably is the cooler as a mercury switch like a Built up spirit level, contacts are provided at certain points, which can be short-circuited by the mercury.

Overall, the technical progress and the inventive Content of the registration subject both by the
