Device for producing endless foam blocks cu

The present invention relates to an apparatus for manufacturing of endless foam blocks with a floor conveyor belt, side walls and adjacent side conveyor belts, and, if necessary, an overhead conveyor belt.

There are devices for the production of endless foam

blocks known, boi which the side walls means in the form a bridge arranged threaded spindles can be shifted against each other, so that the foaming width is set can be. The main disadvantage of such an arrangement is the large amount of work required to adjust the Distance of the sixth walls from each other is required. Since the side walls are used to support the adjacent to them The side walls must be used for guided side conveyor belts be designed accordingly stable. This construction of the side walls is relatively heavy, so your Moving must be extremely careful that the direction of movement is exactly normal to the starting position, otherwise there is a risk of jamming. To adjust the distance between the side walls a device of this type therefore requires several workers.

There is a further disadvantage of these known devices in that the over the floor conveyor belt in the form of a bridge arranged threaded spindles do not allow the attachment of an overhead conveyor belt. This makes it on such a device not possible to produce a dome-free foam block.

The aim of the present invention is to provide an apparatus for producing endless foam blocks, wherein the distance between the side walls can be set or changed in a simple and time-saving manner and where there is also the option of an overhead conveyor belt

to attach.

The device according to the invention for producing endless foam blocks η consists essentially of those that the side walls are attached to the side conveyor belts on swivel arms which can be rotated around a base point, so that they can be rotated by rotating the swivel arms the side walls can be moved parallel to the side conveyor belts by an angle o <.

This construction makes it possible to adjust the distance between the side walls to change from each other quickly and without spending a lot of time, while at the same time still has the advantage that only one man is required to operate the device according to the invention. It is also advantageous that to move the Side walls little force has to be used because the weight of the side walls is borne by the pivot arms. Furthermore, the device according to the invention also allows that Attachment of an overhead conveyor belt, which enables the production of dome-free foam blocks.

It is expedient if at least one swivel arm is arranged at its foot point so that it can be displaced perpendicularly from the floor conveyor belt is. This allows the angle between the side walls include, can be set or changed in a particularly simple manner. Since the setting of this opening angle, that the side walls enclose with each other, each time the Schäumbrecite and thus the distance that the side walls

take from each other, is changed, must be undertaken, the value of this simple arrangement is particularly high. It is particularly advantageous if two opposite one another Swivel arms are arranged at their base points so as to be displaceable perpendicular to the floor conveyor belt, because this reduces the opening angle can be adjusted symmetrically to the conveying direction of the floor conveyor belt.

If the drive of the side conveyor belts is provided in a base point of a swivel arm via a drive roller, in this way a particularly space-saving arrangement is achieved.

The voltage is a respective mechanically operable Anyreßrolle provided for clamping the side conveyor belts, it is possible by means of this pressure roller in a particularly simple manner of the lateral conveyors to be regulated which is always required if the pivot arms are rotated by an angle \.

It is particularly advantageous if the pressure of the pressure rollers is controlled as a function of the angle f \ . With this particularly simple arrangement it can be achieved that the tension of the sidebands is always optimal without the need for additional work to measure and adjust the tension.

In the following, the invention is explained in more detail by way of example with reference to the drawing, which shows a schematic sketch of the device according to the invention.
