Mr. Gerhard Husmann, 4471 Niederlangen No. 5 Device for baling compressible material

The invention provides a device for baling compressible material, such as cardboard boxes, fruit crates and garbage.

On presses of the aforementioned type, the requirements are made that they work reliably and not clog. However, these requirements are due to the large number of different materials that are to be pressed into bales not always to be fulfilled equally. As far as possible, a press should not have any complicated components. It should be robust and simply built to ensure a high level of operational reliability.

The invention is based on the object of creating a device of the type indicated at the outset, which is particularly works reliably and is robustly and simply constructed.

This object has been achieved according to the invention by one of the mouth of a vertical hopper assigned, horizontally extending compression channel, by a plunger which is alternately movable in the compression channel, by an im Filling funnel working, with the plunger coupled tamper and by on the edges that can be moved relative to one another Knives arranged by the piston and the hopper mouth.

The device is preferably designed in such a way that the pusher and piston have a common drive element. This has the advantage that in the device according to the invention loosely thrown material into the hopper is pressed with the pusher through the opening of the hopper when the KoIDen is withdrawn and comes to rest in front of the piston. In yet vorgeschobenem piston of the thus coupled pusher is raised and there is a compaction of the depressed by the pusher material within the bale case _o material, which could not be fully pressed into the bale case from the pusher, is in this case due to the relatively mutually movable edges of the piston and FuI funnel mouth sheared, this shear effect is supported by appropriately attached Hesser. The material entered is pressed into bales in the baling channel.

In the device, the tamper is preferably designed as a two-armed lever pivotable about a horizontal axis, wherein a first lever arm carries the stopper foot pivotable towards the mouth of the hopper, and the wider lever arm connected to the free end of a PIe ueis hinged on the piston is · As described above, this has the advantageous effect that the movements between the pusher and piston are perfect are synchronized with one another, because the pusher is practically dragged along by the piston. The coupling between the pusher and the piston can also be made in such a way that the pusher protrudes radially from a shaft Part is formed and one also radially from the shaft

protruding lever arm is provided, which in turn with the Connecting rod is connected. If the shaft is rotated by being dragged along by the piston, the lever arm and pusher move accordingly.

Preferably one is at the edge of the hopper mouth arranged edge knife adjustable in height. This adjustability allows the distance between the hand knife and the handler of the KoIdens each to be pressed and closed balling material can be turned off. Should z. B. strong cardboard or fruit crate wood are shredded, the two knives must have a slightly larger distance from each other so that a perfect shear effect occurs can·

The hand knife is used to increase the shear effect designed as a half circular ring. When the piston is advanced, the material to be cut and pressed is pressed against the Circular ring knife pressed and is sheared in a pulling cut. The shear pressure is thus on a larger one Distributed area, whereby the force to be exerted by the piston to shear off remains relatively small.

An embodiment of the invention from which further Inventive features result is shown in the drawing. Show it:

Fig. 1 is a schematic side view of the device in section,

Fig. 2 is a schematic plan view of the semicircular hand knife,

Fig. 3 is a half side view of the edge knife according to

Fig. 2 and
4 shows a side view of the ball passage arranged after the baling channel.

In Fig _o 1 the device for crushing and balling of pressable material is shown schematically in a side view in section. 1 with the hopper is designated, which opens into a press channel 3 by means of an inclined hopper wall 2. A piston is slidably arranged in the baling channel, the dead center positions being denoted by a and b. The bottom dead center b is drawn by dashed lines. A pusher 5 can be rotated about a horizontal axis 4 and is designed as a bilateral heoel arm, the first lever arm 6 carrying the stopper foot 7 and the second lever arm 8 being articulated to a connecting rod 9 which is articulated on the piston. The piston has a knife 10 on its upper edge. A peripheral knife 11 is attached to the opposite edge of the mouth of the hopper 1.

The device works as follows: When the piston is withdrawn to position b, the Tamper swung down. It is located in the hopper Material pressed into the press channel 3, which is now free. If the piston moves from its position b into the Position a advanced, so that the cutting of the material to be pressed by the knives and simultaneously a feed

compression takes place within the compression channel 3, pivots also the dragged tamper up again.

In Fig. 2, the hand knife 11 is shown in plan view. It can be seen that the hand knife is semicircular. The mouth of the feed hopper is illustrated as a hatched area.

In Fig. 3 a schematic half-side view is shown. The hand knife is again denoted by 11, and it can be seen how the piston with its knife 10 is movable against the hand knife 11 in the Proßkanal 3. Some intermediate positions of the piston are indicated by dashed lines.

In Fig. 4- a the baling channel 3 downstream he ball passage 13 shown in side view. The pressed Material can spring up again after it exits the baling channel, which causes the inner solidification of a bale partially repealed but at least weakened. The ball duct has a narrowing cross section Partition wall 14, which can be pivoted about the axis 15 Hinged lid is formed. The cross-section of the ball passage can be reduced so that a Type of repressing of the bales takes place. The partition is set using adjusting screws 16.
