Description

The invention relates to a baler for compacting loose material, preferably of cardboard, in which the filling shaft is filled in so-called rear feed, or a lifting / tilting unit for a baler.

Two basic variants of balers are known in the relevant field of technology: In a first basic variant, the baler is charged from the side, in the other from the so-called rear of the baler.

Thus, for example, the company Kampwerth Umwelttechnik GmbH & Co. KG, Germany, there are lifting and tipping devices in various variants, which are designed for a rear feed of a press container. Despite various advantages of a rear feed in comparison to the feed from one side area of the baler, the technical and material complexity of this basic variant is still relatively high, the efficiency of the operation is still relatively low for the operator due to long travel distances.

There are demands on the market according to which the degree of automation for the feeding of balers, in particular of balers with horizontally operating pressing member, which are also referred to as horizontal balers, is to be increased. This means that the feed should be at least semi-automatic, but if possible fully automatic, that is to say with less personnel expenditure, as well as less investment costs and / or reduced consumption costs.

In addition to the performance data of a baling press, the space required to set up and operate a baling press was and is also becoming increasingly important.

The object of the invention is therefore to develop balers, mainly horizontal design, so that the material-technical effort for the production of a baler with rear feed is further reduced, also should as possible also the operating and consumption costs, such as the operation and / or the area required to be lowered, in particular by an improved lifting / tilting unit for a baler.

A baling press of the type mentioned above, advantageously designed for pressing cardboard and other packaging materials, comprises:

• a press room in which the compaction of the loose material into bales takes place at least partially, and optionally a subsequent press channel, wherein the press room and the press channel together can form an assembly if necessary,
• a filling shaft, which is open towards the top, ie opposite to the direction of gravity, and opens down into the pressing chamber,
• a lifting / tilting unit adapted to move a container filled with loose material from a coupling position in which the coupling of the container to the baling press takes place, to a discharge position from which the material falls by gravity into and through the opening of the filling duct passes through the press room, and
• a feed device, designed for advancing the bale in a predetermined feed direction out of the press room, according to the invention
• the lifting / tilting unit is designed for pivoting the container from the coupling position into the emptying position about a pivot axis which runs both perpendicular to the direction of gravity and perpendicular to the direction of advance, and
• is provided for coupling and decoupling of the container designed as a slide-holder unit, wherein the coupling are provided by insertion into the holding unit and the uncoupling by pushing out of the holding unit.

In a first preferred embodiment, the insertion holder has two fork-shaped parallel opposing holding parts, which are fixed to the frame connected to a rotatably mounted about the pivot axis pivoting part. The container, however, is provided with retaining elements which correspond to the geometry of the holding parts on the insertion support, in such a way that the container is guided during insertion and removal by means of the holding parts and held during the pivoting of the holding parts.

In order to enable an ergonomically favorable operation of the baler, the holding parts are advantageously positioned so that the insertion opening for the container is spatially located next to the operating device for the baler, said operating device also includes the controls for the lifting / tilting unit. The insertion of the container into the insertion opening of the insertion bracket is thus carried out here of one of the side areas of the balers and not - as in known devices - from the rear of the baler ago. Also advantageously, the pivoting part and the pivot drive are arranged on the side facing away from the insertion opening and the operating device side of the baler.

In a further preferred embodiment of the baling press, a mechanism for checking the presence of the container in the insert holder is also provided. This control mechanism comprises distance measuring or testing means which allow the evaluation of the actual distance between the container and a reference position in the pivoting part. Particularly preferred in this regard, a proximity sensor is provided and coupled to the operating device so that the triggering of the pivoting movement is possible only in the presence and correct positioning of the container in the insertion holder.

A further preferred embodiment also provides the equipment of the baler with a mechanism for locking the container in the holding unit, wherein the locking is provided in preparation for pivoting and especially during pivoting. In this regard, it is within the scope of the invention to provide electromagnetic coupling elements and to put them with the operating device so in connection that the commissioning of the lifting / tilting unit is possible only when the container is locked.

The baler is preferably designed for use in connection with containers in the form of lattice cars.

This new balers is characterized in particular by the fact that the inventive lifting / tilting unit is suitable due to the orthogonal orientation of the pivot axis relative to the feed direction for the bale and the direction of gravity for a Heckbeschickung and also configured such that a loading of the baler by lattice wagon, such they are common in wholesale markets, can take place.

• eine fliegende Lagerung des Schwenkteiles, das bevorzugt ein Hubbalken ist und sich auf der bedienerabgewandten Seite der Ballenpresse befindet, sowie
• die einfach zu bewerkstelligende Arretierung des Behälters bzw. Gitterwagens durch Arretierungselemente, insbesondere Magnete, in einer am Schwenkteil ausgebildeten gabelförmigen Einschubhalterung.

The lifting / tilting unit is preferably driven hydraulically. Special features of this new lifting / tilting unit for a said baler are

• a flying mounting of the pivoting part, which is preferably a lifting bar and is located on the operator side facing away from the baler, as well as
• the easy to be accomplished locking of the container or lattice by locking elements, in particular magnets, in a formed on the pivoting part fork-shaped insertion bracket.

To turn off the baler or at least the lift and tilt unit when the cart should come loose from the magnet, the presence of the bin by distance gauge or proximity switch during swing is additionally monitored. This also ensures that the lifting / tilting unit can only be operated and operated when the container is docked.

In the Fig.1 Basically illustrated baler 1 of horizontal design is intended for compacting loose material, for example cardboard and other packaging material, and comprises:

• a pressing space 2, in which the compaction of the loose material into bales takes place at least partially, in which case the pressing space 2 is followed by a pressing channel,
• a filling shaft 3, which is upwards, that is opposite to the direction of gravity S, open and opens down into the pressing chamber 2.
• a lifting / tilting unit 4 (extending over a drawing area indicated by dimensional arrows), designed to pivot a container 5 filled with loose material from a coupling position in which the container provided with rollers 14 5 rests on a bottom surface 15 and its coupling to the lifting / tilting unit 4, in a discharge position, from which the material falls due to gravity S in the opening of the hopper 3 and passes through this into the press room 2, and
• a feed device (not shown in the drawing), designed for compacting the loose material and advancing the bale in a predetermined feed direction V from the pressing space 2 addition.

1a ) shows this baler 1 in a side view, 1b shows ) in a plan view.

According to the invention, the lifting / tilting unit 4 of the new baler 1 is designed for pivoting the container 5 about a pivot axis A, which is aligned both perpendicular to the direction of gravity S and perpendicular to the feed direction V. Out Fig. 1 this is apparent insofar as in the side view the direction of gravity S and feed direction V lie in the plane of the drawing, but the pivot axis A is orthogonal to the plane of the drawing. In the plan view, the pivot axis A is aligned parallel to the plane of the drawing.

For coupling and uncoupling of the container 5 to the lifting / tilting unit 4 is a (indicated by a dimensioned by arrows Drawing area extending) insert holder 7 is present, which via a pivot member 8 with a hydraulic cylinder 6 (see. Fig. 3 to Fig. 6 ) is connected as a pivot drive. The insert holder 7 has two parallel holding parts 9, which are arranged fixed to the frame on the pivot member 8. The holding parts 9 form with a partial section of the pivoting part 8 a fork shape.

The container 5 is provided with holding elements 10 which correspond to the geometry of the holding parts 9 so that the container 5 is guided during insertion and removal by means of the holding parts 9 and held and supported by the holding parts 9 during pivoting. The design can also be chosen so that the holding parts 9 are adapted to the geometry of the holding elements 10.

When operating this device, the filled container 5 is manually inserted in the direction of R1, that is from the side, in the insertion holder 7 and after pivoting upward in the emptying position and pivoting back into the coupling position by manually pushing in the direction R2 from the insertion bracket 7 and thus decoupled from the baler 1.

The hydraulic cylinder 6 is connected via a drive circuit, not shown in the drawing, to an operating device 11. The operating device 11 preferably comprises in addition to the Controls for the entire baler 1 and the controls for the lifting / tilting unit. 4

A particular advantage of the arrangement according to the invention results from the fact that the opening for the insertion of the container 5 is positioned on the insertion support 7 spatially at a short distance next to the operating device 11. Thus, for the operation of the baler 1 including the operation of the lifting / tilting unit 4 and the coupling and uncoupling of the container 5 only small paths are required. The baler 1 is thus ergonomically advantageous. The pivoting part 8 and its drive, the hydraulic cylinder 6, are arranged on the insertion bracket 7 and the operating device 11 side facing away from the baler 1, which is in terms of ergonomics and especially in terms of occupational safety advantage. At the same time immediately adjacent to the baler 1 in the rear area less tread for the operator is required, which also the space required for the installation and operation of the baler is lower overall than in known in the art solutions.

In the embodiment described here by way of example, the lifting / tilting unit 4 is equipped with a control mechanism either in the form of a distance measuring device which measures the distance between the container 5 and the pivoting part 8 during insertion of the Container 5 in the insertion bracket 7 qualitatively assessed in terms of reaching a given as a prerequisite for pivoting concrete distance measure, or in the form of a test agent that quantitatively assesses this distance in the sense of the mere presence of the container 5 in the position, as a prerequisite for Panning is given.

Preferably, in this regard, a proximity sensor 12 is provided and coupled to the operating device 11 and the control for the hydraulic cylinder 6 so that the commissioning of the lifting / tilting unit 4 is possible only in the presence of the container 5 in the insertion holder 7.

With this arrangement, a mechanism for locking the container 5 in the insertion bracket 7 can be controlled. In the embodiment described here, such a locking mechanism, for example, electromagnetic coupling elements 13, which are coupled to the operating device 11 and the control for the hydraulic cylinder 6 so that the commissioning of the lifting / tilting unit 4 only in the presence of the container 5 in the insertion bracket 7 and turned lock is possible.

Fig. 2 shows a concretely executed lifting / tilting unit 4 of the baler 1 according to the invention as a single module. On the Representation of a container 5 has been omitted here for reasons of clarity, whereby the design of the insertion holder 7 is clearly visible. It will be in Fig. 2 as well as in the following figures for the same components always the same reference numerals according to the reference numerals used, so that a description of the relevant modules for each figure is not required again.

Fig. 3 shows the lifting / tilting unit 4 with docked container 5, wherein the container 5, for example in the form of a lattice carriage, is in the coupling position.

Fig. 4 and Fig. 5 show the lifting / tilting unit 4 in moment depictions during pivoting of a docked container 5 in various constellations and perspectives.

Fig. 6 shows the constellation of the lifting / tilting unit 4 on reaching the emptying position of the container 5 above the feed tube after its pivoting.

Out Fig. 7 the insertion bracket 7 without inserted container 5 can be seen, in which case again the fork shape can be seen.

Fig. 8 shows the insertion bracket 7 with already partially inserted container 5. In this situation, the correct position of the container 5 in the insertion bracket 7 is not yet reached. The proximity sensor 12 consequently blocks the operation of the locking mechanism and also the start-up of the lifting / tilting unit 4.

In Fig. 9 the container 5 is completely inserted into the insertion holder 7. In this constellation, the proximity sensor 12 confirms the presence of the container 5 in the rack 7, the container 5 is then locked, and the readiness to start the lifting / tilting unit 4 is signaled to either the operator or automatically initiated.

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 disclosed in connection with the present 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.

Thus, an embodiment of the baler 1 and the lifting / tilting unit 4 in the context of the invention, in which the holding parts 9 indeed also parallel as already described and record the container 5 on two opposite sides of its circumference leadership, the pivoting part. 8 However, is formed so that a portion of the pivoting member 8 engages under the container 5 so that it is raised during lifting and tilting of the under-engaging pivot portion and supported during pivoting, while the holding parts 9 and the holding elements 10 have only holding and guiding function.

A further embodiment consists in the fact that the two holding parts 9 of the insertion holder 7 are designed to have different lengths. As a result, the insertion of a container 5 is further facilitated.
