CHIP AND NON-FIBER DISTRIBUTOR - DELNINGSANORDNING FOR EN SPÅN- ELLER FIBERMATTA

The present invention relates to a chip or non-fibrous splitting or non-fibrous splitting device for conveying or holding a carpet on a conveyor belt or the like, the device comprising means for performing the splitting or splitting.

10

For example, in the manufacture of particle board, devices are used which cut off a continuous uncut passing through a conveyor (usually a planar belt or wire) in the transverse direction or divide it into two or more lanes in the conveying direction.

Carpet cutting is required if a synchronous press is used in the particle board process. In this case, the continuous cutting mat to be formed on the conveyor must be cut (as the conveyor passes) into parts of the press-20 length, which are further conveyed in the so-called with an acceleration conveyor to the press or to the press filling device. When cutting the carpet, the workpiece must be traversed across a continuous mat without following an oblique path suitable for the speed of the mat and at a suitable speed, so that the mat must be cut perpendicular to the direction of transport.

The division of the conveyor belt moving on a conveyor belt into strips is needed, for example, when the width of the mat to be fed to the press has to be reduced to a certain extent. In each case, a chip of 30 tons is separated from each edge and the desired width of the mat is continuously removed before the press. Shirts dividing the chip mat must be movable to the desired workplace.

35 At present, the above tasks are generally carried out by sawing a chip mat with pydrivii blade discs, similar to circular sawing. The sawing is usually combined with a pneumatic suction, which is used to remove loose chips separated from the carpet during the sawing.

Currently known devices are relatively heavy in construction and complex with saw blades, saw motors, guards and pneumatic piping. This is a detrimental list because the device must be quick and easy to move. The weight of the equipment also results in heavy support structures, rails, and transfer mechanisms.

10

The result of the circular sawing is not good enough. It is difficult to adequately protect the saw blade. It tends to throw the chip that surrounds the chips it removed on top, ruining the surface of the final plate. The sawn edge of the carpet is not smooth enough and tii-15 vis. For safety reasons, the saw blade cannot be placed very close to the surface of the conveyor belt or wire, as touching the blade may damage the above surfaces. A larger clearance worsens the sawing result. The use of pneumatic suction is uneconomical and causes emission problems.

The object of the invention is to provide a simple and inexpensive non-cutting distributor with which the above-mentioned disadvantages can be eliminated. The invention is characterized in that the means for carrying out the cutting or dividing is a vibrating element placed above the conveyor belt close to or substantially attached to the belt, and in which the element has a non-cutting tip which divides the mat in the direction of encounter.

A preferred embodiment of the invention is characterized in that the vibrating element is formed by a vibrating plate which is vertical to the plane of the surface of the mat and substantially in the longitudinal direction of the mat.

Another preferred embodiment of the invention is characterized in that the tip dividing the mat of the tile plate is connected to the tile plate by a wing forming an acute angle with which the diverging strip of the mat is plowed to the side.

A further preferred embodiment of the invention is characterized in that the story of the board is provided by a tare of the desired frequency and amplitude connected to the board, such as a compressed air meter, a jet engine or an electric board.

The construction according to the invention is simple and relatively light, so that the support structures, rails and movement mechanisms of the device can also be relatively light and simple.

The invention will now be described in more detail with reference to the accompanying drawing page, in which Figure 1 schematically shows a top view of a dispenser according to the invention.

Figure 2 shows a section along the line II-II in Figure 1.

Figures 20 shows a conveyor belt 1 and its overlying carpet chip 2, which extends in the direction of the arrow 3. The chipboard 4 is divided into strips, which in the embodiment shown in the figures is perpendicular to the plane of the surface of the chipboard or nonwoven 2 and is substantially longitudinal to the mat and extends 25 close to or substantially attached to the surface of the conveyor belt 1. The floorboard is gripped at a suitable frequency and amplitude by means of a gripper 5. The tarot can be any known beam source that provides a suitable power and frequency, e.g., a pneumatic motor, a steam motor, or an electric motor. In this to-30 embodiment example, the board board unit is in place and the chip mat runs toward the board board. However, it is equally possible that the board plate 4 moves when dividing the chip mat, so that the mat can be in place. When the unchipped chip encounters a crumbling, narrow ridge 6 of the board, then at a high frequency the crumbling candy moves the chip to either side of the board, and there is no pile of stagnant chips in front of the ridge 6.

4 91616 When vibrating, the plate constantly opens an opening for the chipboard to be fed to it. Because the amplitude of the tile plate is small, it does not tend to throw chips. The chips therefore do not fly over the uncut 2. The vibrating movement is oriented in such a way that it 5 tends to seal the edge 8 of the uncut, whereby it becomes tight and straight. The apex of the tile plate dividing the carpet is connected to the tile plate by a wing forming an acute angle, with which the diverging strip of the mat is plowed to the side. By fitting the vane plate suitably, the second lane 10 au-10 track can be suitably sideways. The plowing angle can be relatively steep, because the plowing blade 9 grooves, reducing friction.

The floor plate 4 can be placed relatively close to the surface of the conveyor 15, as it does not cause a pressure comparable to that of a circular saw on the surface of the conveyor.

The truss plate 4 with its gripper 5 is fastened to the frame 12 of the run-20 by means of flexible elements 11, e.g. suitable rubber plates, springs, etc. If necessary, behind the tine plate and the wing, in the carpet-free conveyor belt part, near the conveyor belt surface a pneumatic suction belt is arranged. for cleaning.

It will be apparent to those skilled in the art that the invention is not limited to the exemplary embodiments set forth above, but may be varied within the scope of the appended claims. Above, we have mostly talked about the chip mat and the conveyor belt below it. Equally, the invention can be used to cut a nonwoven fabric or web on a wire.
