Abstract

The invention relates to a channel baling press for compacting loose material and for binding the compacted material into bales comprising a hopper which is open at the top and through which the loose material passes into a press box in which the compacting takes place wherein the hopper has a pivotable side wall which is internally adjacent to one of the lateral boundary walls of the press box and that in the transition region from the side wall to the boundary wall a wall plate is arranged, which is selectively pivotable in the direction of the press box.

Description

The invention relates to a channel baling press for compacting loose material and for binding the compacted material into bales comprising a hopper which is open at the top and through which the loose material passes into a press box in which the compacting takes place ,

Balers are known and described for example in DE 198 18 127 C1 . DE 42 23 046 C2 as well as in the offers of different manufacturers, such as HSM GmbH + Co. KG, Welger GmbH or Kampwerth Umwelttechnik GmbH, respectively Germany, or Dimitron AG, Switzerland. They are used for compacting loose material, such as cardboard and cardboard packaging, in order to transport it in the form of bales to save space and possibly reuse it as valuable material. Bales are easy to stack and thus contribute to optimal loading and storage space utilization.

There are various types of balers widespread, including channel baling presses, which is also the subject of this patent. Compaction takes place after the loose material has entered the press channel. To insert the loose material in the press box / press channel is a funnel, which is located above the press box and opens into this.

Due to the arrangement of the filling shaft over the press channel / press box, the filling opening is located at a relatively high level above the footprint of the channel baler. It is customary to fill the loose material into containers, transport the filled containers to the channel baler and lift them to the required height and then tilt at that height so that the material falls through the filler opening into the well.

The disadvantage here is that, depending on the care of the operator when filling the transport container and the emptying selbiger into the hopper and depending on the nature of the poured into the hopper waste material in the transition region between the end of the hopper and the beginning of the press box / press channel so-called material bridges that prevent the falling of further waste material into the press box. Usually such bridges are resolved by the operator with rods and the like tool. However, this operation entails accident hazards in itself, as the operator comes to a position on the baler, which normally runs counter to the safety regulations and must first be turned off the baler, which entails additional work and work interruption.

Against this background, the object of the present invention is to develop a baler said type so that the elimination of said possible material bridges in the filling of the press can be eliminated with technically simple and above all safe tools.

The present task is inventively achieved with a channel baler with the features of claim 1. The subordinate claims 2 to 6 disclose embodiments or developments of the invention.

The essence of the invention is that in the critical transition region from the inner side wall of the feed tube to the input area of the press box, a means is provided by the optional actuation of the resulting in certain circumstances under certain circumstances material bridges are loosened so quasi, so that the Material can then fall unhindered into the press box.

In an advantageous embodiment of the invention, this means for releasing a material bridge is a pivotable wall plate. Advantageously, this wall plate is integral with one of the lateral boundary walls of the press box or integral with an inner sliding surface of the side wall of the feed tube, which is preferably pivotable.

The invention will be explained in more detail with reference to an embodiment. In the accompanying drawings show in a partly schematic representation:

1 a perspective view of the new channel baler;

2 the channel baler behind 1 in a sectional view with a view into the press box and the filling shaft of the channel baler facing the press channel;

3 the schematic representation after 2 but with pressed wall plate and

4 a perspective view overlooking the actuating lever for the pivotable wall plate.

In 1 is the channel baling press according to the invention 1 shown in a perspective view. You can see a funnel 2 through it loose, to be compacted material in a press channel 3 reaches, in which the compression takes place. For the sake of clarity, the presentation of the bales has been omitted, which, as is known, between the lateral boundary walls 4 , a bottom plate and a cover plate formed pressing channel 3 run through.

The filling shaft 2 has a side wall 7 on, which is about an axis perpendicular to the direction of gravity axis 8th is pivotable in the direction of rotation D. And that is the pivoting of a first to a second end position and vice versa possible. Of these two end positions is in 1 the first end position shown.

A mobile transport container 9 in the form of a trolley, which serves to receive loose, intended for pressing material is by means of a coupling device 10 mechanically fixed with the swiveling sidewall 7 connected.

After a pivoting movement of the transport container 9 in its upper temporary end position the material falls over the filling shaft 2 in the press box 4 , Thereafter, the transport container 9 returned to its original position. This moment is in the 2 shown. There is schematically indicated that the filled material in the transition region 6 a material bridge has formed, which prevents all filled material in the press box 4 can fall. By pressing in the transition area 6 integral in the above the boundary wall 4 lying lying portion of the filling shaft pivoting wall plate 14 is, by pivoting in the direction of the filling shaft 2 or of the press box 5 , the material bridge dissolved, so that all filled waste material in the press box 5 can fall. This moment is in the 3 shown.

For the operation of the swiveling wall plate 14 is outside near the filling shaft 2 in the exemplary embodiment shown on the non-pivotable side wall 11 of the filling shaft 2 , an operating lever 15 provided that with a shaft the sidewall 11 passes through and with the pivot axis of the wall plate 14 connected is; see also 4 ,

The wall plate 14 can even be formed over the entire surface or rake-like, this is chosen depending on the size of the wall plate to be selected 14 , so depending on the size of the channel baler.

This disclosure provides illustrative embodiments of the invention by way of example and not limitation. Those skilled in the art can devise numerous other modifications and embodiments that fall within the spirit and scope of the inventive principles.

The invention is not limited to the illustrated and described embodiment, but in particular also includes variants that can be formed by combining features or elements described in connection with the present invention.

Furthermore, individual features or modes of operation described in conjunction with the figures can in themselves constitute an independent invention. The Applicant therefore reserves the right to claim features of significance essential to the invention which have hitherto been disclosed only in the description, in particular in conjunction with the figures. The claims filed with the application are thus merely formulation suggestions without prejudice to achieve further patent protection.
