PACKING PRESS AND METHOD FOR PACKAGING

DEFORMABLE MATERIAL

FIELD OF THE INVENTION

The present invention relates to a packaging press for packaging deformable material and a method for packaging deformable material by means of a packaging press.

BACKGROUND OF THE INVENTION

Packaging presses for packaging deformable material are generally known, which press deformable material into a package by means of two-dimensional or three-dimensional compression.

Packing presses come in, for example, at scrap yards, in body pressing plants

Aluminum processing plants and in the sheet metal processing industry to optimize logistics as well as in steelworks, foundries and remelting plants to increase the

Melting power used.

The material to be pressed comprises a wide range of light to medium-heavy ferrous and non-ferrous metals.

A packaging press for three-dimensional compression typically has a filling pressure compressor, an intermediate pressure compressor and a finishing pressure compressor, which are each moved by hydraulic cylinders, and a filling box, which is filled with the material to be pressed.

The filling pressure compressor is arranged on one side of the filling box and presses the material to be pressed into a pressing box, which is arranged on the side of the filling box that corresponds to the

Filling pressure compressor is opposite.

In the press box, the material to be pressed is turned into a package from above by the intermediate pressure compressor and laterally, across the filling pressure compressor, by the finished pressure compressor

pressed together.

In the case of packaging presses for two-dimensional compaction, it is known that the

Intermediate pressure compressor can be omitted. The package can then, for example, be delimited at the top by a hydraulically movable cover of the filling box. The lid can be opened to load the filling box and closed to compress the material to be pressed. The underside of the closed cover can lie directly above the top of the filling pressure compressor. The package can be ejected from the press box by opening a hydraulic door on the side of the press box opposite the final pressure compressor and pushing the package through the hydraulic door using the final pressure compressor.

Known package presses typically require eight work cycles to press material to be pressed into a package and to eject it from the press box.

The object of the present invention is to provide an improved packaging press and an improved method for packaging deformable material by means of a packaging press.

SUMMARY OF THE INVENTION

In a first aspect, the present invention provides a packaging press according to claim 1.

In a second aspect, the present invention provides a method according to claim 17.

Further aspects and features of the present invention will become apparent from the dependent claims, the accompanying drawings and the description below

Embodiments.

Some embodiments of the present invention relate to a packaging press for packaging deformable material, which comprises a first press box, a second press box and a compressor which is arranged between the first and the second press box in such a way that, when actuated in a first direction, in the first Press box engages and engages in the second press box when actuated in a second direction.

The packaging press can, for example, press material to be pressed, which comprises deformable material, by compression into a package, which is referred to as packaging. The material to be pressed can be compressed, for example, two-dimensionally or three-dimensionally, the volume of the material being reduced.

The material to be pressed can be, for example, a wide range from light to

include medium-heavy ferrous metals and / or non-ferrous metals. It can include scrap metal such as scrap or swarf or the like.

In some embodiments, the packaging press is designed as a scrap press.

The material to be pressed can be compressed by the compressor exerting a mechanical force in the direction of the compression on the material to be pressed. For example, the compressor can be moved in the direction of compression. Actuation of the compressor can, for example by a hydraulic system, such as a hydraulic cylinder, which pushes the compressor in the direction of compression.

The compressor can comprise a pressure plate, via which the compressor exerts the mechanical force on the material to be pressed.

The compressor may also include a wear plate. The wear plate can be detachably attached to the pressure plate, or the pressure plate can be designed to receive a wear plate.

In some exemplary embodiments, the pressure plate does not touch the material to be pressed directly, but rather via the wear plate, so that wear of the pressure plate is reduced to a negligible extent. The wear plate can be designed so that it can be replaced with relatively little effort if it has become unusable due to wear.

The first press box can be designed to absorb a mechanical force which is exerted by the compressor. The first press box can, for example, comprise an end wall which is aligned parallel to a pressure plate and / or a wear plate of the compressor. The material to be pressed can be compressed, for example, by pressing the material to be pressed in the first press box by the compressor with the pressure plate and the wear plate against the end wall.

The compressor is designed such that it engages in the first press box when actuated in a first direction.

In some embodiments, the compressor is actuated in a first direction before it can engage the first press box so that it moves toward the first press box.

The compressor engages in a press box if part of the compressor or a pressure plate attached to it is in a space section which is enclosed by the convex casing of the press box. For example, the compressor engages in the press box when a part of the compressor or a pressure plate attached to it closes an opening of the press box flush with an inner wall of the press box.

The second press box can be configured similarly or identically to the first press box.

It can also be designed to absorb a mechanical force which is exerted by the compressor, for example via an end wall which is aligned parallel to a pressure plate and / or a wear plate of the compressor, material to be pressed being in the second

Press box is pressed by the compressor with the pressure plate and the wear plate against the front wall. The compressor is designed such that it engages in the second press box when actuated in a second direction.

In some embodiments, the compressor is actuated in a second direction before it can engage the second press box so that it moves towards the second press box.

In some embodiments, the compressor is disposed between the first and second press boxes, and the first and second press boxes each include an opening that faces the compressor.

If the compressor is then actuated in a first direction, it moves, for example, towards the first press box and at the same time away from the second press box until it is in the first

Press box engages. If, on the other hand, it is actuated in a second direction, then it moves, for example, towards the second press box and at the same time away from the first press box until it engages in the second press box.

The first direction and the second direction can be different directions. In some exemplary embodiments, the first direction and the second direction are opposite to one another.

In some exemplary embodiments, the first press box is arranged in a first press wing and the second press box is arranged in a second press wing. The first and / or the second press wing can be part of the packaging press.

The first and second press wings can be arranged opposite one another so that the compressor is located between the first press wing and the second press wing and, when actuated, moves in the first direction towards the first press box and, when actuated, moves in the direction of the second press box moves.

In addition to a press box, a press wing can also comprise, for example, an intermediate pressure compressor, a finished pressure compressor and a door and other components.

In particular, a press wing can comprise an intermediate pressure compressor if a package is to be produced by three-dimensional compression. Should a package go through

two-dimensional compaction can be produced, then the press wing can without

Intermediate pressure compressor to be executed.

In some exemplary embodiments, the first press wing and the second press wing are configured similarly or identically.

In some exemplary embodiments, the first and / or the second press box each have a guide section which is provided for guiding a package. The guide section can be provided, for example, for guiding a package which has been produced in the press box by compression of material to be pressed while the package is being ejected from the press box, for example through a door.

In some exemplary embodiments, this can prevent the package from twisting or wedging when it is ejected in the press box and thus preventing ejection.

In some embodiments, the guide section is formed by a vertical offset.

For example, the vertical offset can be formed in that a bottom of the press box is vertically offset to a bottom of a filling box.

The bottom of the press box can, for example, be offset downward from the bottom of the filling box.

The guide section can be arranged such that it runs parallel to the direction of ejection of the package.

In some embodiments, the guide section is located under an opening of the press box through which the compressor engages the press box, and the package is ejected transversely to the direction in which the compressor engages the press box.

In some embodiments, the package is then ejected from the guide section and the compressor is not needed to guide the package when ejected.

In some embodiments, the packetizing press is configured to move the compressor from the first press box to the second press box while a package is being ejected from the first press box and to move the compressor from the second press box to the first press box while a package is out of the second Press box is ejected.

As a result, several, for example two or three, work steps can be carried out in parallel in some exemplary embodiments of the packaging press according to the invention.

For example, while a first package made in the first press wing from the first

Press box is ejected by opening a door of the first press box in a first step and / or pushing the first package with a final pressure compressor of the first press wing through the door out of the first press box in a second work step, can be used to produce a second package can be started in the second press wing by moving the compressor to the second press box in a third step.

If the first package is ejected from the first press box before the material to be pressed has been pressed into the second press box with the compressor, then the door of the first can Press box closed and / or the finished pressure compressor of the first press wing can be moved back while the compressor is moved to the second press box.

In some exemplary embodiments, three, otherwise two work steps are carried out in parallel at times, while in a known packaging press, at most two work steps can be carried out in parallel and at times only one work step can be carried out.

In some exemplary embodiments, this can save time by producing more packages per unit of time in comparison to a known packaging press.

In some embodiments, a package is required to be guided by a guide portion when it is ejected so that the compressor is not needed to guide the package and can be moved away from the press box from which the package is being ejected while the package is being ejected.

In some exemplary embodiments, the compressor is designed as a filling pressure compressor.

The filling pressure compressor can, for example, convey material to be pressed, for example from a filling box, into the first and into the second press box and a first one

Perform compaction step, that is, compress the material in a first direction.

In some exemplary embodiments, the packaging press further has a first and a second filling box section, the compressor conveying material from the first filling box section to the first press box and from the second filling box section to the second press box.

For example, the first filling box section can be arranged in front of the first press box and the second filling box section can be arranged in front of the second press box.

Then, when the compressor is moved to the first press box, it pushes material from the first fill box section into the first press box, and when it is moved to the second press box, it pushes material from the second fill box section into the second press box.

In some embodiments, the packaging press further comprises a material feed, the material feed selectively the first filling box section and the second

Filling box section loaded with material.

For example, the material feeder can feed material to be pressed directly to the first filling box section while the compressor is being moved to the second press box or engages in the second press box, and to feed material to be pressed directly to the second filling box section while the compressor is being moved to or into the first press box engages the first press box. In some embodiments, the material is loaded by filling material into a funnel, for example through a conveyor belt or a handling device.

In some embodiments, a chute is arranged below the funnel, which guides the material into the filling box section to be loaded.

The slide can be configured, for example, to be tiltable or pivotable, so that the first filling box section is selectively loaded when the slide is first aligned, and that the second filling box section is selectively loaded when the slide is aligned a second time.

In some exemplary embodiments, however, the material is also loaded by filling material into a first hopper for loading the first filling box section, and by filling material into a second hopper for loading the second filling box section.

The material can then be loaded, for example, by a handling device or by a swiveling conveyor belt. In the case of a pivotable conveyor belt, the first or the second filling box section can be loaded selectively via its alignment.

In some embodiments, a slide is arranged below the first and the second funnel, which guides the material into the corresponding filling box section.

The first and second funnels can also be designed as double funnels.

In some embodiments, the material feeder indirectly and selectively feeds the first and second filling box sections by guiding material to be pressed onto the top of the compressor and selectively stripping it off into the first or second filling box sections.

In some exemplary embodiments, the packaging press further comprises a filling box, which has the first filling box section and the second filling box section, the compressor being arranged in the filling box.

For example, the first filler box section can be arranged at one end of the filler box and the second filler box section can be arranged at an opposite end of the filler box. The compressor can then be arranged in the filling box in such a way that the compressor is moved in the first direction in the direction of the first filling box section when actuated and in the direction of the second filling box section in the second direction when actuated.

In some exemplary embodiments, the filling box is arranged between the first and the second press box.

For example, the filling box can be arranged between the first and the second press box such that the first filling box section borders the first press box and the second filling box section borders the second press box. In some embodiments, the compressor, when actuated in a first direction, is moved through the first fill box section to the first press box and, when operated in a second direction, is moved through the second fill box section to the second press box.

In some exemplary embodiments, a bottom of the filling box can be displaced vertically.

For example, the filling box can comprise a bottom and a housing and can be configured such that the bottom of the filling box with screw connections, with washers, with

Perforated wedges or similar can be moved vertically against the housing of the filling box.

The filling box can be designed in such a way that the housing of the filling box is not displaced when the bottom of the filling box is moved vertically, but that a compressor arranged in the filling box is also displaced.

Both the bottom and the housing of the filling box can comprise wear plates.

In some embodiments, a shear knife is arranged on an upper edge of a pressure plate of the compressor and a cutting edge is arranged on an upper edge of an opening in a press box, so that material that protrudes beyond the upper edge of the opening when the press box is filled with the compressor through the opening Shear forces between the shear knife and the cutting edge is separated.

Then a vertical distance and thus a play between the shear knife and the cutting edge can be adjusted by vertically shifting the bottom of the filling box. For example, it may be advantageous to set a play of a few tenths of a millimeter between the shear knife and the cutting edge in order to ensure that excess material is cut off at the cutting edge without the compressor wedging on the cutting edge.

In some exemplary embodiments, the bottom of the filling box comprises two bottom sections which can be displaced vertically independently of one another. The bottom of the filling box can comprise, for example, a first bottom section, which is arranged in a first filling box section, and a second bottom section, which is arranged in a second filling box section, so that, by vertically displacing the first bottom section, there is play between a shear knife on a first filling box section Side of the compressor and a cutting edge of a press box arranged on the first filling box section can be adjusted, and that by moving the second bottom section vertically, play between a shear knife on a side of the second filling box section facing the Compressor and a cutting edge of a press box arranged on the second filling box section can be adjusted.

In some embodiments, the fill box is mechanically connected to the first and / or second press box.

In some exemplary embodiments, a mechanical connection between the filling box and a press box can ensure that material is compressed between the compressor and an end wall of the press box and that the press box is not displaced or knocked over by the compressor.

In some exemplary embodiments, the packaging press further comprises a hydraulic system (and / or a pneumatic and / or other drive device) which connects the compressor with a door of the first and / or second press box and / or a final pressure compressor of the first and / or second press box Ejecting the package hydraulically coupled such that the door and / or the final pressure compressor can be operated together with the compressor. In this way, in some exemplary embodiments, three, otherwise two work steps can be carried out in parallel at times.

For example, the packaging press can be designed so that the package with a

Final pressure compressor is ejected through a door from a press box, the

Compressor, the final pressure compressor and the door are operated hydraulically.

The compressor can be moved from a first cylinder in a first direction to the first press box and from a second cylinder in a second direction to the second press box.

Hydraulic fluid that is forced out of the first cylinder when the compressor is moved in the second direction can be used to open a first door in the first press box and to eject the package from the first press box through the first door with a pre-pressure compressor.

Hydraulic fluid that is forced out of the second cylinder when the compressor is moved in the first direction can be used to open a second door in the second press box and to eject the package from the second press box through the second door with a final pressure compressor.

In some embodiments, this can save time because two steps, namely ejecting the package and moving the compressor out of the press box, or three steps, namely opening the door, ejecting the package and moving the compressor out of the press box, be carried out in parallel (at least in part). In some embodiments, two or more hydraulic cylinders are provided to actuate the compressor in one direction. A number of hydraulic cylinders which are provided for actuating the compressor in the first direction can correspond to a number of hydraulic cylinders which are provided for actuating the compressor in the second direction.

Some embodiments of the present invention relate to a method of packaging deformable material with a packaging press, such as described herein, comprising: operating the compressor in a first direction to engage the first press box; Pressing deformable material into a package in the first press box; and actuating the compressor in a second direction so that it engages in the second press box, the package from the first being actuated in the second direction during actuation of the compressor

Press box is ejected.

The method or the work steps described herein can be implemented in a controller for the packaging press, e.g. B. as instructions issued by a computer, processor,

Microcontroller or the like are executed and lead to the execution of the method or the work steps of the packaging press described herein.

In some exemplary embodiments, the control can be integrated in the packaging press. In some exemplary embodiments, the packaging press is alternatively or in combination with the control mechanically configured such that it can carry out the work steps described herein.

In some embodiments, more packages can be produced per unit of time than with a known packaging press or with a known method, because the compressor is moved away from the first press box while the package is being ejected and the compressor is simultaneously moved in a second direction and material in transported the second press box.

DETAILED DESCRIPTION OF EMBODIMENTS

Before a detailed description of the exemplary embodiments of the invention, explanations regarding the structure and function of a packaging press according to the prior art are given first with reference to FIGS. 1 a and 1b or in the following also to FIGS. 2 to 7.

1 and FIG. 1b show a packaging press 1 according to the prior art.

The packaging press 1 has a hopper 2 (only in FIG. 1b), a filling box 3, a press box 4, a filling pressure compressor 5, a filling pressure cylinder 6, a shear knife 7, a cutting edge 8 and stops 9 for the filling pressure compressor 5. The packaging press also includes 1 one

Intermediate pressure compressor 10, an intermediate pressure cylinder 11, stops 12 for the Intermediate pressure compressor 10, a final pressure compressor 13, a final pressure cylinder 14, a package chamber 15, a door 16 and a wiper 17.

The packaging press 1 is fed via the hopper 2 by means of a crane, a conveyor belt, a slide or a scale. The funnel 2 opens into the filling box 3, so that material to be pressed, which is filled into the funnel 2, falls into the filling box 3.

The filling box 3 is laterally delimited by two side walls, an opening to the press box 4, which adjoins one end of the filling box 3, and a pressure plate of the filling pressure compressor 5. Below, the filling box 3 is delimited by a bottom.

The filling pressure compressor 5 is at one end of the press box 4 opposite the

Filling box 3 is arranged and is moved horizontally by the filling pressure cylinder 6, a hydraulic cylinder. The filling pressure compressor 5 comprises a pressure plate, with which the pressure forces of the filling pressure compressor 5 are transmitted to the material to be pressed, and a wear plate (not shown), which reduces wear of the filling pressure compressor 5.

Material to be pressed, which is located in the filling box 3, is pressed into the pressing box 4 by the filling pressure compressor 5 by extending the filling pressure cylinder 6. Excess material of the material to be pressed, which protrude upward beyond the pressure plate of the filling pressure compressor 5, is between the shear knife 7, which is on the upper edge of the pressure plate of the

Filling pressure compressor 5 is attached, and the cutting edge 8, which is arranged on the upper edge of the opening to the press box 4, separated.

The adjustable stops 9 on the filling pressure compressor 5 ensure that the

Filling pressure compressor 5 reaches an end position which is plane-parallel to an end wall of the press box 4. The distance between the pressure plate of the filling pressure compressor 5 in the end position and the opposite end wall of the press box 4 corresponds to the width of the package to which the material to be pressed is pressed.

The stops 9 can be aligned as desired with shims. In this way, it can be set how far the filling pressure compressor 5 engages in the press box 4. In some embodiments, it is advantageous to set the stops 9 so that the

Wear plate of the filling pressure compressor 5, the opening of the press box 4 flush with the

Closes the inner wall of the press box 4, wherein a slight play, for example of a few tenths of a millimeter, can prevent the final pressure compressor 13 from hitting the wear plate of the filling pressure compressor 5 when driving forward and thus blocking the pressing process.

Material to be pressed, which is located in the press box 4, is moved vertically from the

Intermediate pressure compressor 10 pressed to a height that corresponds to the height of the package. The intermediate pressure compressor 10 is moved by the intermediate pressure cylinder 11, a hydraulic cylinder, and comprises a pressure plate with which the pressure forces of the

Intermediate pressure compressor 10 are transferred to the material to be pressed, as well as a

Wear plate (not shown), which reduces wear of the intermediate pressure compressor 10.

In addition, the intermediate pressure compressor 10 is provided with stops 12. The stops 12 are lined with shims and come into contact with a housing of the packaging press 1 when a plane-parallel end position of the intermediate pressure compressor 10 is reached. The end position, and thus the height of the package, can be set with the shims.

Furthermore, material to be pressed, which is located in the press box 4, is pressed horizontally and transversely to the working direction of the filling pressure compressor 5 by the finished pressure compressor 13 to a length which corresponds to the length of the package.

The finished pressure compressor 13 is moved by the finished pressure cylinder 14, a hydraulic cylinder. The finished pressure compressor 13 comprises a pressure plate with which the compressive forces of the finished pressure compressor 13 are transmitted to the material to be pressed, and which to the

Cross section of the package is adapted, as well as a wear plate (not shown), which reduces wear on the final pressure compressor 13.

The final pressure compressor 13 is switched off via a pressure switch when the material to be pressed has been pressed into a package of the desired, variably adjustable length.

The section of the press box 4 in which the finished pressed package is located is

Parcel chamber 15. The parcel chamber 15 is vertically delimited by a floor and by the pressure plate of the intermediate pressure compressor 10. The side of the package chamber 15 is delimited by the pressure plate of the filling pressure compressor 5 and the opposite end wall of the press box 4 and by the pressure plate of the finished pressure compressor 13 and the door 16 opposite it.

The door 16 can be opened and closed hydraulically and is used to eject the finished pressed package from the package chamber 15.

In order to press the material to be pressed into a package, a packaging press 1 according to the prior art requires eight work cycles.

The packaging press 1 is loaded in the first work cycle.

The first compression step takes place in the second cycle. The filling pressure compressor 5 presses the material to be pressed located in the filling box 3 for pre-compression horizontally into the

Press box 4. Material to be pressed, which protrudes beyond the filling box 3, is separated from the shear knife 7 at the cutting edge 8.

After the second work cycle, the material to be pressed already has the width of the package, which is given by the width of the press box 4.

The filling pressure compressor 5 remains in the advanced position after the second work cycle.

The work takes are now described with reference to FIGS. 2 to 7.

2 shows the packaging press 1 after the second working cycle. The filling pressure compressor 5 has advanced. The intermediate pressure compressor 10 and the final pressure compressor 13 are

pulled back. The door 16 is closed.

The hopper 2 can continue to be fed; the filled material is from

Filling pressure compressor 5 is stopped and only falls into the filling box 3 when the filling pressure compressor 5 is moved back in a later working cycle. The filling box 3 is therefore fed indirectly.

The second compaction step takes place in the third cycle. The intermediate pressure compressor 10 is advanced and presses the material to be pressed from above to the final package height for intermediate compression. The intermediate pressure compressor 10 also remains in the advanced position.

In Fig. 3, the packet press 1 is shown after the third cycle. The filling pressure compressor 5 and the intermediate pressure compressor 10 have advanced. The finished pressure compressor 13 is retracted. The door 16 is closed.

The third compression step takes place in the fourth cycle. The final pressure compressor 13 is advanced horizontally and presses the material to be pressed to the final package length for final compression. The finished pressure compressor 13 also remains in the advanced position.

After the fourth work cycle, the material to be pressed lies in the package chamber 15 as a finished pressed package with the final dimensions.

The package is enclosed by the pressure plates of the filling pressure compressor 5, the intermediate pressure compressor 10 and the final pressure compressor 13, as well as by the end wall and bottom of the press box 4 and the door 16.

4 shows the packaging press 1 after the fourth working cycle. The filling pressure compressor 5 and the intermediate pressure compressor 10 have advanced. The final pressure compressor 13 has advanced so far that the package is pressed to the desired length. The package is now in the package chamber 15. The door 16 is closed.

In the fifth work cycle, the filling pressure compressor 5 and the

Final pressure compressor 13 and then the intermediate pressure compressor 10. Simultaneously with the pressure relief of the intermediate pressure compressor 10, the door 16 on the side of the package chamber 15 opposite the finished pressure compressor 13 is opened by means of hydraulic separation. Hydraulic separation means that the pressure relief of the

Intermediate pressure compressor 10 and the opening of the door 16 via mutually independent

Hydraulic systems take place.

After the fifth work cycle, the parcel lies tension-free in the parcel chamber 15.

5 shows the packaging press 1 after the fifth working cycle. The filling pressure compressor 5 and the intermediate pressure compressor 10 have advanced, but do not exert any pressure on the package. The finished pressure compressor 13 has advanced to the desired package length, but likewise does not exert any pressure on the package. The parcel is tension-free in the parcel chamber 15. The door 16 is open.

In the sixth work cycle, the parcel is ejected from the parcel chamber 15 through the opened door 16 by further advancing the finished pressure compressor 13.

The package is guided laterally through the pressure plate of the filling pressure compressor 5 and from above through the pressure plate of the intermediate pressure compressor 10, so that it does not become wedged horizontally or vertically, thereby hindering the ejection process.

6 shows the packaging press 1 after the sixth working cycle. Of the

Filling pressure compressor 5 and the intermediate pressure compressor 10 are advanced, but do not exert any pressure. The final pressure compressor 13 has advanced so far that the package is ejected through the door 16. The door 16 is open.

After the sixth work cycle is behind the fully advanced

Final pressure compressor 13 a cavity. If the filling pressure compressor 5 were retracted behind the cutting edge 8 at this time, material falling into the filling box 3 could penetrate into the cavity and hinder stroke movements of the finished pressure compressor 13.

Therefore, in the seventh cycle, the finished pressure compressor 13 alone is partially retracted until the cavity is closed.

7 shows the packaging press 1 after the seventh work cycle. The filling pressure compressor 5 and the intermediate pressure compressor 10 have advanced. The finished pressure compressor 13 is retracted so far that no more material can penetrate into the cavity behind the finished pressure compressor 13. The door 16 is open. Then, in the eighth work cycle, the filling pressure compressor 5, the intermediate pressure compressor 10 and the finished pressure compressor 13 are moved back to their starting positions. Door 16 is also closed.

The filling pressure compressor 5 is retracted and the

Final pressure compressor 13 over a remaining distance by means of hydraulic coupling, that is to say by means of a predetermined oil takeover, so that the filling pressure compressor 5 and the

Final pressure compressor 13 are retracted together during the

Intermediate pressure compressor 13 and the door 16 are retracted by means of hydraulic separation.

When the filling pressure compressor 5 moves back, the path for material to be pressed located in the hopper 2 into the filling box 3 is opened. Material lying on the filling pressure compressor 5 is stripped off into the filling box 3 at the stripper 17.

After the eighth work cycle, the packaging press 1 is again in the initial state.

The eight work cycles of a state-of-the-art packaging press are serial and take a lot of time.

An exemplary embodiment of a packaging press according to the invention is described below

8 and following, here configured as a twin press 20, which is designed to produce sufficiently pressed packages in a shorter time and with less wear, less energy consumption and / or less required space requirement per produced package than the known one described above Packing press 1 according to the prior art.

The twin press 20 has a left press wing 21a, a right press wing 21b, a filling box 22 and a filling pressure compressor 23.

The fill box 22 is arranged between the left press wing 21a and the right press wing 21b and has a left fill box section 22a and a right fill box section 22b. The left hopper section 22a is a section of the hopper 22 that is on the left

Pressing wing 21a borders, and the right filling box section 22b is a section of the filling box 22 that borders on the right pressing wing 21b.

The fill box 22 also has a bottom 42 (not shown in Fig. 8). In the present exemplary embodiment, the floor 42 comprises a left floor section 42a, which is in the left Filling box section 22a is arranged, and a right bottom section 42b, which is arranged in the right filling box section 22b.

The filling pressure compressor 23 is arranged in the filling box 22.

If the filling pressure compressor 23 is actuated in the direction of the left pressing wing 21a, then the filling pressure compressor 23 in the filling box 22 moves through the left filling box section 22a to the left pressing wing 21a. If, on the other hand, the filling pressure compressor 23 is actuated in the direction of the right pressing wing 21b, the filling pressure compressor 23 in the filling box 22 moves through the right one

Filling box section 22b to the right press wing 21b.

The filling pressure compressor 23 has two pressure plates, a left filling pressure plate 23a and a right filling pressure plate 23b, with which pressure forces can be transmitted from the filling pressure compressor 23 to material to be pressed.

The filling pressure compressor 23 further comprises two wear plates (not shown). One wear plate each is attached to the left filling pressure plate 23a and to the right filling pressure plate 23b in order to reduce wear on the filling pressure compressor 23.

The inflation pressure compressor 23 also includes an upper connector 23c and lower connectors 23d to which the portions of the inflation pressure compressor 23 are connected to which the left inflation pressure plate 23a and the right inflation pressure plate 23b are attached.

The left press blade 21a has a press chamber 24 and a package chamber 24a _(j each case not shown in Fig. 8). The package chamber 24a is a section of the press box 24 which has the dimensions of a finished pressed package and in which a finished pressed package lies after the pressing.

The press box 24 also has an end wall 24b (not shown in FIG. 8), which is arranged opposite the left filling pressure plate 23a, so that material to be pressed can be compressed in the filling box 24 between the end wall 24b and the left filling pressure plate 23a.

The left press wing 21a also has an intermediate pressure compressor 25, one

Final pressure compressor 26 and a door 27 and an intermediate pressure cylinder 28, one

Finished pressure cylinder 29 and stops 30 for the intermediate pressure compressor 25.

The intermediate pressure compressor 25 is arranged vertically. It has a pressure plate with which pressure forces can be transmitted from the intermediate pressure compressor 25 to the material to be pressed, and a wear plate (not shown) which prevents wear of the

Intermediate pressure compressor 25 reduced.

The intermediate pressure compressor 25 is moved by the intermediate pressure cylinder 28, a hydraulic cylinder, and presses material to be pressed that is in the press box 24 of the left Pressing wing 21a is located from above into the package chamber 24a of the left pressing wing 21a. The material to be pressed is pressed to a height that corresponds to the height of a package to be produced.

The height of the package to be manufactured can be made with adjustable stops 30 for the

Intermediate pressure compressor 25 can be set. In some embodiments, the stops 30 ensure that the intermediate pressure compressor 25 reaches a plane-parallel end position.

The finished pressure compressor 26 is arranged horizontally and is moved by the finished pressure cylinder 29, a hydraulic cylinder. The finished pressure compressor 26 also has a pressure plate with which pressure forces can be transmitted from the finished pressure compressor 26 to the material to be pressed, as well as a wear plate (not shown), which wear the

Final pressure compressor 26 reduced.

The final pressure compressor 26 presses material to be pressed located in the press box 24 of the left press wing 21a transversely to the working direction of the filling pressure compressor 23 into the package chamber 24a of the left press wing 21a. The material to be pressed is pressed to a length that corresponds to the length of the package to be produced.

The package chamber 24a of the left pressing wing 21a is a section of the pressing box 24 of the left pressing wing 21a in which a finished pressed package lies, and is on the

Finished pressure compressor 26 opposite side bounded by the door 27. The door 27 is opened and closed hydraulically. It serves to eject a finished pressed package from the package chamber 24a of the left press wing 21a.

The right press blade 21b has a press chamber 31 and a package chamber 31 (not _j in each case shown in Fig. 8). The package chamber 31a is a section of the press box 31 which has the dimensions of a finished pressed package and in which a finished pressed package lies after the pressing.

The press box 31 also has an end wall 31b (not shown in FIG. 8), which is arranged opposite the right filling pressure plate 23b, so that material to be pressed can be compressed in the filling box 31 between the end wall 31b and the right filling pressure plate 23b.

The right press wing 21b also has an intermediate pressure compressor 32, one

Finished pressure compressor 33 and a door 34 and an intermediate pressure cylinder 35, one

Finished pressure cylinder 36 and stops 37 for the intermediate pressure compressor 32.

The intermediate pressure compressor 32 is arranged vertically. It has a pressure plate with which pressure forces are transferred from the intermediate pressure compressor 32 to the material to be pressed can, as well as a wear plate (not shown), the wear of the

Intermediate pressure compressor 32 reduced.

The intermediate pressure compressor 32 is moved by the intermediate pressure cylinder 35, a hydraulic cylinder, and presses material to be pressed, which is located in the press box 31 of the right press wing 21b, from above into the package chamber 31a of the right press wing 21b. The material to be pressed is pressed to a height that corresponds to the height of a package to be produced.

The height of the package to be manufactured can be adjusted with 37 for the

Intermediate pressure compressor 32 can be set. The stops 37 ensure this

Embodiment that the intermediate pressure compressor 32 reaches a plane-parallel end position.

The finished pressure compressor 33 is arranged horizontally and is moved by the finished pressure cylinder 36, a hydraulic cylinder. The finished pressure compressor 33 has a pressure plate with which pressure forces can be transferred from the finished pressure compressor 33 to material to be pressed, as well as a wear plate (not shown) which reduces wear of the finished pressure compressor 33.

The final pressure compressor 33 presses material to be pressed located in the press box 31 of the right press wing 21b transversely to the working direction of the filling pressure compressor 23 into the package chamber 31a of the right press wing 21b. The material to be pressed is pressed to a length that corresponds to the length of the package to be produced.

The package chamber 31a of the right presser wing 21b is a portion of the press box 31 of the right presser wing 21b in which a finished pressed package lies, and is on the

Finished pressure compressor 33 opposite side bounded by the door 34. For example, the door 34 can be opened and closed hydraulically. It is used to eject a finished pressed package from the package chamber 31a of the right pressing wing 21b.

The door 27 of the left press wing 21a and the door 34 of the right press wing 21b can be arranged on the same side of the twin press 20, so that packets produced from both

Pressing wings 21a, 21b are ejected in the same direction. However, the door 27 and the door 34 can also be arranged on opposite sides of the twin press 20, so that packets produced are ejected from the press wings 21a, 21b in opposite directions. The latter is shown in Fig. 8.

The left press wing 21a and the right press wing 21b are connected to the common fill box 22, so that the press box 24 of the left press wing 21a and the press box 31 of the right press wing 21b are arranged at opposite ends of the common fill box 22. The press box 24 of the left press wing 21a and the press box 31 of the right press wing 21b are here mechanically connected to the common filling box 22.

The press box 24 of the left press wing 21a and the press box 31 of the right press wing 21b can be arranged parallel to one another; In this exemplary embodiment, they are arranged linearly, for example, the common filling box 22 being arranged between the press box 24 and the press box 31.

The filling pressure compressor 23 is arranged centrally in the common filling box 22. Of the

Filling pressure compressor 23 has the left filling pressure plate 23a and the right filling pressure plate 23b. Thereby, the common fill box 22 becomes the left fill box section 22a and the right one

Filling box section 22b divided.

The filling pressure compressor 23 presses material to be pressed, which is in the left

Filling box section 22a is located with the left filling pressure plate 23a in the press box 24 of the left pressing wing 21a, and presses material to be pressed, which is located in the right filling box section 22b, with the right filling pressure plate 23b into the pressing box 31 of the right pressing wing 21b.

The filling pressure compressor 23 is moved from a hydraulic telescopic cylinder 38 to the left

Pressing wing 21a pressed, which is concentrically connected to a rear side of the left filling pressure plate 23a.

The filling pressure compressor 23 is also pressed by two hydraulic telescopic cylinders 39a and 39b to the right presser wing 21b, which are connected laterally offset with a rear side of the right filling pressure plate 23b.

9 shows a side view of a twin press 20 according to the invention.

The telescopic cylinder 38 and the telescopic cylinders 39a and 39b are attached to a common mechanical support 40, a so-called crossbar 40. The cross member 40 is fixed relative to the common filling box 22.

When the telescopic cylinder 38 or the telescopic cylinders 39a and 39b are extended, the left filling pressure plate 23a and the right one shift due to a mechanical connection

Filling pressure plate 23b and due to the fixed arrangement of the telescopic cylinder 38 and

Telescopic cylinders 39a and 39b on the cross member 40 both the left filling pressure plate 23a and the right filling pressure plate 23b parallel to the connecting line of the press boxes 24, 31 of the left

Press wing 21a and the right press wing 21b.

The mechanical connection between the left filling pressure plate 23a and the right one

Filling pressure plate 23b is here, inter alia, by the upper connecting piece 23c and the lower Connecting pieces 23d are provided so that the filling pressure compressor 23 moves together with the left filling pressure plate 23a and the right filling pressure plate 23b.

The upper connecting piece 23c and the lower connecting pieces 23d serve for additional mechanical strength when the filling pressure compressor 23 is moved.

The top of the inflation compressor 23 includes two sections through the top

Connection piece 23c are connected via an elongated groove. The top

The connecting piece 23c is fastened with blind screws, the heads of which are flush with the top of the filling pressure compressor 23, so that the blind screws do not get caught with wipers 47, 48. The self-tapping screws are arranged in the groove. The forces that occur during compression are not via the self-tapping screws, but rather are in contact with one another

Cross-sectional areas of the upper connector 23c and the top portions of the

Transfer pressure compressor 23 transferred. The self-tapping screws therefore only serve to fasten the upper connecting piece 23c, but not to transmit power.

The lower connecting pieces 23d are designed as two square bars 23d. They are also connected via a groove to sections of the filling pressure compressor 23 and to one

Screw connection attached, which is arranged in the groove. Here, too, the force is not transmitted via the screw connection, but via cross-sectional areas of the lower one

Connecting pieces 23d and the cross-sectional areas of sections of the filling pressure compressor 23 in contact therewith. Accordingly, the screw connection here also does not serve for the transmission of force, but only for fastening the lower connecting pieces 23d.

The inflation pressure compressor 23 and the inflation pressure plates 23a and 23b are therein

Embodiment not provided with adjustable stops, which ensure that a plane-parallel end position is reached. A final position is achieved using thinner

Washer plates fixed between the working pistons of the telescopic cylinders 38, 39a and 39b and the associated baffle plates.

As can be seen from FIG. 9, a bottom 41 of the press box 31 of the right press wing 21b is also offset downward relative to a bottom section 42b of the right fill box section 22b.

The right-hand part of FIG. 9 shows the package chamber 31a, that is to say the section of the press box 31 in which a finished pressed package lies.

Due to the vertical offset of the bottom 41 of the press box 31 relative to the bottom section 42b of the right filling box section 22b, a finished pressed package is guided when it is ejected. This can prevent the package from wedging when it is ejected, thereby preventing the ejection.

With a package width of 400 millimeters and a package height of 400 millimeters, as in the present exemplary embodiment, the vertical offset between the bottom 41 of the press box 31 and the bottom section 42b of the right filling box section 22b can be, for example, 40 millimeters.

Due to the vertical offset between the bottom 41 of the press box 31 one

Pressing wing 21b and the bottom portion 42b of the right filling box portion 22b, the filling pressure plate 23b is not needed to guide the package when ejecting.

Therefore, parallel to a work step in which the intermediate pressure cylinder 35 and the finishing pressure cylinder 36 of the right pressing wing 21b are relieved, the telescopic cylinder 38 can be extended into the material to be pressed via the left filling pressure plate 23a

Press box 24 of the left press wing 21a presses.

Due to the mechanical connection 23c, 23d between the left filling pressure plate 23a and the right filling pressure plate 23b, the right filling pressure plate 23b is also displaced and presses partial links of the telescopic cylinders 39a, 39b into their starting position.

In the present exemplary embodiments, return oil, which is pressed out of the telescopic cylinders 39a and 39b, is not fed back into a hydraulic tank, but is used by means of hydraulic coupling, that is to say an inevitable predetermined oil transfer, for opening the door 34 and for ejecting the package by the final pressure compressor 33.

Accordingly, it is possible in the present case that step parallel to a work in which

Intermediate pressure cylinder 28 and finished pressure cylinder 29 of the left press wing 21a are relieved, the telescopic cylinders 39a and 39b are extended, which press material to be pressed via the right filling pressure plate 23b into the press box 31 of the right press wing 21b.

Due to the mechanical connection 23c, 23d between the left filling pressure plate 23a and the right filling pressure plate 23b, the left filling pressure plate 23a is also displaced and presses partial elements of the telescopic cylinder 38 into their starting position.

In addition, in the present embodiment, return oil, which is from the

Telescopic cylinder 38 is pressed, not fed back into a hydraulic tank, but used by means of hydraulic coupling to open the door 27 and to eject a package by the final pressure compressor 26. In this way, the number of packets produced per unit of time can be reduced compared to the prior art according to FIGS. 1 to 7.

The twin press 20 also has a shear knife 43 and a cutting edge 44, with which material is separated, which protrudes when pressing material to be pressed into the press box 24 of the left press wing 21a beyond the filling pressure compressor 23, as well as a shear knife 45 and a cutting edge 46, with which Material is separated that protrudes beyond the filling pressure compressor 23 when the material to be pressed is pressed into the press box 31 of the right press wing 21b.

In addition, the twin press 20 has a scraper 47, the material to be pressed, which when the filling pressure compressor 23 moves away from the left press wing 21a on the

Filling pressure compressor 23 lies in the left filling box section 22a, and a stripper 48 which strips material to be pressed, which lies on the filling pressure compressor 23 when the filling pressure compressor 23 is moved away from the right pressure wing 21b, into the right filling box section 22b.

In the present exemplary embodiment, since the filling pressure compressor 23 is moved away from the left press wing 21a while a finished pressed package is being ejected from the press box 24 of the left press wing 21a by the finished pressure compressor 26, material to be pressed could fall into the left fill box section 22a while the finished pressure compressor 26 is advancing .

In order to prevent material in the press box 24 from moving forward

Finished pressure compressor 26 falls and hinders retraction of the finished pressure compressor 26, in the present exemplary embodiment the finished pressure compressor 26 is of sufficient length so that even when the finished pressure compressor 26 is advanced, no material can get behind the finished pressure compressor 26.

For example, the length of the final compression compressor 26 can be at least the length of the

Press box 24 of the left press wing 21a, as shown in Fig. 8.

The same applies to the length of the final pressure compressor 33 of the right press wing 21b.

10 and 11 are exemplary embodiments for loading the inventive

Twin press 20 illustrated.

While a parceling press 1 according to the prior art is fed, for example, via a conveyor belt and a hopper 2, the material flow running uniformly via the sole filling box 3 into the sole pressing box 4, material to be pressed in a twin press 20 according to the invention is fed via two filling box sections 22a, 22b in two

Press boxes 24, 31 conveyed. Depending on the position of the filling pressure compressor 23, press material is filled into either the left fill box section 22a or the right fill box section 22b to be pressed into the corresponding press box 24 or 31.

The following are two exemplary embodiments for the periphery of a twin press 20 according to the invention for loading the left filling box section 22a and the right one

Filling box section 22b (in some embodiments, the periphery also belongs to the twin press).

A twin press 20 according to the invention is illustrated in FIG. 10, the periphery of which comprises a single hopper 49 and a slide 50.

The single hopper 49 is mounted on a mechanical support.

This feeds the twin press 20 via a conveyor belt or through a

Handling equipment enables.

Material to be pressed is directed from the exit of the single hopper 49 onto the slide 50.

The slide 50 is mechanically connected to a basic structure of the twin press 20 and, in the present exemplary embodiment, hydraulically, depending on the desired material flow of the material to be pressed, by tilting in the direction of the press box 24 on the left

Pressing wing 21a or the right pressing wing 21b are aligned.

11 illustrates a twin press 20 according to the invention, the periphery of which comprises a double hopper 51 and a double slide 52.

The double funnel 51 is mechanically attached to a carrier and is divided into two funnels, which guide material to be pressed onto one side of the double slide 52.

The double slide 52 is mechanically connected to the double funnel 51 and forwards the material to be pressed in a targeted manner into the corresponding filling box section 22a, 22b.

The twin press 20 from FIG. 11 is fed through the double hopper 51 by means of a handling device or by means of a pivotable conveyor belt.

An exemplary embodiment of the twin press 20 with means for aligning and securing the bottom 42 of the filling box 22 is illustrated in FIG. 12.

So that the filling pressure compressor 23 can be guided against tilting torque, in particular during a cutting process, if protruding material on the shear knife 43 and on the

Cutting edge 44 or on the shear knife 45 and on the cutting edge 46 is severed Bottom 42 of the filling box 22 of the twin press 20 aligned and secured by various components.

Traverses 53 are arranged below the bottom 42 of the filling box 22 transversely to the connecting line of the two press wings 21a and 21b and are connected to the bottom 42 by screw connections.

The bottom 42 of the filling box 22 can be adjusted in the vertical direction by the screw connections.

In addition, a further crossmember 54 is arranged at each of the opposite ends of the filling box 22, which is shown in detail in the lower part of FIG. 12 as an example for one end of the filling box 22.

The traverse 54 counteracts a tilting moment that occurs during the cutting process and enables a clearance between the

Shear knife 43 and the cutting edge 44 or between the shear knife 45 and the

Cutting edge 46.

So that the play between the shear knife 43 or 45 and the cutting edge 44 or 46 can be exactly aligned, the cross member 54 is vertically adjusted at both ends with two perforated wedges 55 each.

The perforated wedges 55 are fixed with a vertical threaded rod 56 with lock nuts 57 and with a horizontal threaded rod 58.

To further secure the bottom 42 of the filling box 22 and to reduce the play between the shear knife 43 or 45 and the cutting edge 44 or 46, two tapered square bars 59 are also arranged at the two ends of the filling box 22.

The square irons 59 are each adjustable under the crossbar 54 via a threaded rod 60 and are fixed with a wedge 61 which belongs to a stand of the packaging press 20.

An interaction of the trusses 53, the trusses 54, the perforated wedges 55, the vertical

Threaded rods 56 with lock nuts 57, the horizontal threaded rods 58, the

Square iron 59, the threaded rods 60 and the wedge 61 enable precise alignment of the filling pressure compressor 23.

In some exemplary embodiments, the filling pressure compressor 23 can be kept in a vertical floating state using trapezoidal wear plates and can only be guided horizontally. As a result, in some exemplary embodiments, fewer

Signs of wear occur. An exemplary method according to the invention for packaging deformable material with a packaging press, such as the twin press 20 explained above, is described below.

In the following description of an exemplary method, six work cycles are shown in FIGS. 13a to 17b, which are carried out serially and cyclically in a packaging press according to the invention designed as a twin press 20.

Since the work cycles of the twin press 20 are carried out cyclically, the work cycles can be numbered at any work cycle. For better comprehensibility, the numbering of the work cycles is chosen here in such a way that a package is produced in the left press wing 21a from the first to the sixth work cycle.

In a first work cycle, the left filling box section 22a of the twin press 20, which adjoins the pressing box 24 of the left pressing wing 21a, is loaded with material to be pressed.

13a and 13b illustrate the twin press 20 after the first work cycle.

The filling pressure compressor 23 is moved away from the left pressing wing 21a, so that a maximum filling box section 22a between the left pressing wing 21a and the left filling pressure plate 23a is free and can be filled with material.

The material can be loaded, for example, via a conveyor belt, a handling device, a funnel, a slide or a combination thereof, as was also explained above.

Material filled in the left filling box section 22a remains on the bottom 42 of the

Filling box 22 lie between the left press wing 21a and the left filling pressure plate 23a.

In the first work cycle, the finished printing cylinder 29 and the cylinder 63 are in their

Starting positions retracted. This means that the left final pressure compressor 26 from

Finished pressure cylinder 29 moved out of the left press box 24 and the door 27 from

Cylinder 63 is closed.

The finished pressure compressor 26 is first driven back a section alone until it is on

Closing the door 27 is not affected.

Thereafter, the remaining distance is moved back together with the door 27 by means of hydraulic coupling of the finished pressure compressor 26. Return oil, which is produced when the final pressure compressor 26 is retracted, is supplied to the cylinder 63, which is thereby extended and closes the door 27.

The hydraulically movable units of the left press wing 21a are in a starting position after the first work cycle. The intermediate pressure compressor 25, which is moved by the hydraulic intermediate pressure cylinder 28, has moved upwards and the intermediate pressure cylinder 28 has been retracted.

The finished pressure compressor 26, which is moved by the hydraulic finished pressure cylinder 29, has moved out of the press box 24 of the left press wing 21a and the finished pressure cylinder 29 has been retracted.

The door 27, which is moved by a hydraulic cylinder 63, is closed and the

Cylinder 63 is extended.

As a result, the press box 24 of the left press wing 21a is free and can be filled via an opening to the fill box 22.

At the same time, the filling pressure compressor 23 has moved in the direction of the right pressing wing 21b.

The filling pressure compressor 23 is moved by the telescopic cylinder 38 and by the telescopic cylinders 39a and 39b. The telescopic cylinder 38 is retracted, the telescopic cylinders 39a and 39b are extended.

The filling pressure compressor 23 engages with the right filling pressure plate 23b and / or a wear plate attached to it, in the press box 31 of the right pressing wing 21b.

The intermediate pressure compressor 32, which is moved by the hydraulic intermediate pressure cylinder 35, has moved down as far as the stops 37 allow, and the intermediate pressure cylinder 35 is extended.

The final pressure compressor 33, which is moved by the hydraulic final pressure cylinder 36, is driven into the press box 31 of the right press wing 21b in the first work cycle and performs a third compression step for the final compression of material located in the press box 31 into a package.

After the first work cycle, the finished pressure compressor 33 has moved up to a predetermined length of a package into the press box 31 and the finished pressure cylinder 36 has been partially extended accordingly.

The door 34, which is moved by a hydraulic cylinder 65, is closed and the

Cylinder 65 is extended.

In the press box 31 of the right press wing 21b, for example, there can be a package that has been pressed from deformable material in the press box 31 in previous work cycles, including the first work cycle.

The section of the press box 31 in which the finished pressed package is located is that

Parcel chamber 31a. The telescopic cylinder 38 is extended in a second working cycle.

14a and 14b illustrate the twin press 20 after the second work cycle.

When the telescopic cylinder 38 is extended, the filling pressure compressor 23 becomes the left one

Pressing wing 21a moves.

Material which is located in the left filling box section 22a between the left press wing 21a and the left filling pressure plate 23a, for example because it is in the left in the first working cycle

Filling box section 22a has been filled, the filling pressure compressor 23 with the

Filling pressure plate 23a is conveyed into the press box 24 of the left press wing 21a.

Material which projects beyond the filling pressure compressor 23 is separated by a shearing action between the shear knife 43, which is arranged on an upper edge of the filling pressure compressor 23, and the cutting edge 44 and remains, for example, on the filling pressure compressor 23.

The filling pressure compressor 23 is so far in the direction of the left by the telescopic cylinder 38

Pressing wing 21a moves that the filling pressure compressor 23, with the left filling pressure plate 23a and / or a wear plate attached to it, engages in the press box 24 of the left pressing wing 21a.

The telescopic cylinder 38 is extended until an end position is reached. The end position can be with thin washers between a baffle plate and a working piston of the

Telescopic cylinder 38 can be adjusted.

Material that is in the press box 24 is compressed between the left filling pressure plate 23a and the end wall 24b of the press box 24 to a predetermined package width.

This is a first compression step for pre-compression, in which the material is compressed in a first direction, namely in the working direction of the filling pressure compressor 23.

As soon as the filling pressure compressor 23 engages in the press box 24, the left one can

Filling box section 22a between the left press wing 21a and the stripper 47 are indirectly fed with further material to be pressed. The material stays on the

Filling pressure compressor 23 are located and is stripped off in a later work cycle on the scraper 47 in the left filling box section 22a.

The intermediate pressure compressor 25, the final pressure compressor 26 and the door 63 remain in their starting position in the second working cycle.

The filling pressure compressor 23 is also moved away from the right presser wing 21b by the extension of the telescopic cylinder 38. The right filler box section 22b between the right filler pressure plate 23b and the press box 31 of the right presser wing 21b is free and can now be loaded directly with material to be pressed.

It may happen that there is material to be pressed on the filling pressure compressor 23 between the stripper 48 and the right press wing 21b, for example because it has a

Material feed has been filled into the twin press 20 during the

Filling pressure compressor 23 has engaged in the press box 31 of the right pressing wing 21b, or because when the filling pressure compressor 23 was moved in the direction of the right pressing wing 21b it was cut off by a shearing action between the shear knife 45 and the cutting edge 46.

This material is when moving the filling pressure compressor 23 in the direction of the left

Pressing wing 21a stripped from the stripper 48 into the right filling box section 22b between the right filling pressure plate 23b and the pressing box 31.

When moving the filling pressure compressor 23 to the left press wing 21a, the

Telescopic cylinder 39a and 39b compressed between the filling pressure compressor 23 and the crossbar 40. Hydraulic fluid, for example hydraulic oil, hereinafter referred to as return oil, is pressed out of the telescopic cylinders 39a and 39b.

The return oil is not fed back into a hydraulic tank unused, but is used to eject a package from the press box 31 of the right press wing 21b.

To eject the package, the intermediate pressure cylinder 35 and the finished printing cylinder 36 are relieved of pressure so that the package lies in the press box 31 without tension.

To eject the package, the door 34 is opened by the cylinder 65 with the return oil from the telescopic cylinders 39a and 39b and the finished pressure compressor 33 is moved further into the press box 31 by the finished pressure cylinder 36, so that the finished pressure cylinder 36 pushes the package through the door 34 out of the press box 31 pushes out. The package is guided at a vertical offset between a bottom 41 of the press box 31 and the right bottom section 42b of the filling box 22, so that it does not become wedged and prevents ejection.

In addition, the package is guided from the pressure plate of the intermediate pressure compressor 32 when it is ejected so that it does not become wedged.

In a third work cycle, the intermediate pressure cylinder 28 is advanced. The intermediate pressure compressor 25 of the left press wing 21a is pressed down into the press box 24.

15a and 15b illustrate the twin press 20 after the third cycle. The material in the press box 24 is arranged with the vertically

Intermediate pressure compressor 25, which is moved by the intermediate pressure cylinder 28, to a

predetermined package height pressed.

This is a second compression step for intermediate compression of the material to be pressed. The material is in a second direction, namely the working direction of the

Intermediate pressure compressor 25, compressed.

The intermediate pressure compressor 25 includes adjustable stops 30 with which it can be ensured that the intermediate pressure compressor 25 reaches an end position in which one

Pressure plate of the intermediate pressure compressor 25 is plane-parallel to a bottom of the press box 24.

The intermediate pressure compressor 25 is moved a longer distance than one

Intermediate pressure compressor 10 of a parcel press 1 according to the state of the art, because the bottom of the press box 24 is offset downwards relative to the left bottom section 42b of the filling box 22, so that a parcel can be guided at the vertical offset thus formed and does not become wedged when it is ejected.

The filling pressure compressor 23, the finished pressure compressor 26 and the door 27 are not moved in the third work cycle. Accordingly, the filling pressure compressor 23 continues to engage in the press box 24, the finished pressure compressor 26 remains outside the press box 24 and the door 27 remains closed.

The intermediate pressure compressor 32 of the right press wing 21b can be moved out of the press box 31, for example, in the third working cycle by moving the intermediate pressure cylinder 35 upward.

The final pressure compressor 33 and the door 34 are not moved in the third work cycle.

Accordingly, the final pressure compressor 33 remains moved into the press box 31 and the door 34 remains closed.

The finished printing cylinder 29 is advanced in a fourth work cycle. The

The final pressure compressor 26 of the left press wing 21a is moved into the press box 24.

16a and 16b illustrate the twin press 20 after the fourth working cycle.

The final pressure compressor 26 is in a horizontal, transverse to the working direction of the

Filling pressure compressor 23 arranged guide channel into the press box 24 until it reaches a predetermined position and is switched off, for example, by a pressure switch. The pre-pressed material located in the press box 24 is pressed in a third direction, namely in the working direction of the final pressure compressor 26, to a predetermined package length. This is a third compression step to final compression.

The material to be pressed now lies as a finished pressed package with the predetermined ones

Dimensions in the press box 24 of the left press wing 21a. The section of the press box 24 in which the finished pressed package lies is the package chamber 24a.

The filling pressure compressor 23, the intermediate pressure compressor 25 and the door 27 are not moved in the fourth work cycle. Accordingly, the filling pressure compressor 23 continues to engage in the press box 24, the intermediate pressure compressor 25 has continued to move into the press box 24 from above and the door 27 is still closed.

The final pressure compressor 33 is moved out of the press box 31 of the right press wing 21b in the fourth work cycle and the door 34 is closed. The intermediate pressure compressor 32 is not moved in the fourth working cycle and accordingly continues to be moved upwards out of the press box 31.

In a fifth work cycle, the finished pressed package is ejected from the press box 24 of the left press wing 21a.

17a and 17b illustrate the twin press 20 after the fifth cycle.

The finished pressed package is at the beginning of the fifth work cycle in the package chamber 24a of the left pressing wing 21a from the left filling pressure plate 23a, the pressure plate of the

Intermediate pressure compressor 25, the pressure plate of the final pressure compressor 26, the door 27 and a floor and the end wall 24b of the press box 24 surround.

So that the package after opening the door 27 from the final pressure compressor 26 from the

Press box 24 can be ejected, the package is in a tension-free state.

In order to achieve this stress-free state, the following work steps are carried out in parallel:

The intermediate pressure cylinder 28 and the finished pressure cylinder 29 are depressurized, the telescopic cylinders 39a and 39b are extended, the door 27 is opened and the finished pressure compressor 26 is moved further into the press box 24 and thus pushes the package through the door 27 out of the press box 24 .

The pressure relief of the intermediate pressure cylinder 28 and the finished pressure cylinder 29 is provided so that the package lies stress-free in the package chamber 24a. When the telescopic cylinders 39a and 39b are extended, the filling pressure compressor 23 is moved away from the left press wing 21a.

On the one hand, this is also provided so that the package lies in the package chamber 24a without tension.

On the other hand, material to be pressed, which lies in the right filling box section 22b between the stripper 48 and the pressing box 31 of the right pressing wing 21b, can be from

Filling pressure compressor 23 is already conveyed into the press box 31 and in a first one

Compression step can be pre-compressed while the package is ejected from the press box 24 of the left press wing 21a.

In addition, material to be pressed that is between the left press wing 21a and the

Scraper 47 lies on the filling pressure compressor 23, when the filling pressure compressor 23 moves to the right presser wing 21b on the stripper 47 in the left filler box section 22a between the press box 24 of the left presser wing 21a and the left filler pressure plate 23a.

In order to prevent the package from becoming wedged in the press box 24 when ejected, and that

Ejection hindered, it must be guided when ejecting.

In a packaging press 1 according to the prior art, a package is guided when it is ejected from a filling pressure plate of a filling pressure compressor 5.

Since the filling pressure compressor 23 of the twin press 20 is moved away from the press box 24 during the ejection of the package, the filling pressure compressor 23 is not available for guiding the package during the ejection.

The twin press 20 therefore has a guide section in the form of a vertical offset between a bottom of the press box 24 and the left bottom section 42a of the fill box 22. The bottom of the press box 24, and thus the guide channel in which the

Finished pressure compressor 26 is moved, is offset against the left bottom portion 42a of the filling box 22 down.

This vertical offset is dimensioned sufficiently so that the package can be guided without being stabilized by the left filling pressure plate 23a when it is ejected and does not become wedged.

The package is also guided by the pressure plate of the intermediate pressure compressor 25 during ejection so that it does not become wedged.

The telescopic cylinder 38 is compressed by the extension of the telescopic cylinders 39a and 39b and the corresponding movement of the filling pressure compressor 23. Hydraulic fluid, for example hydraulic oil (but can also be any other fluid), hereinafter referred to as return oil, which is pressed out of the telescopic cylinder 38, is used to open the door 27 with the cylinder 63 by means of hydraulic coupling and the final pressure compressor 26 with the finishing cylinder 29 further into the press box 24

to drive in.

As a result, the package is pushed out of the press box 24 by the finished pressure compressor 26 through the door 27. The package is guided at the vertical offset so that it does not become wedged and prevents ejection.

The intermediate pressure compressor 32 and the final pressure compressor 33 of the right pressing wing 21b remain moved out of the pressing box 31 in the fifth working cycle, and the door 34 remains closed.

The work steps which are carried out in the fifth work cycle in the right press wing 21b by actuating the telescopic cylinders 39a and 39b correspond to work steps which are carried out in the second work cycle in the left press wing 21a by actuating the telescopic cylinder 38.

In the sixth cycle, the intermediate pressure cylinder 28 is in its starting position

moved back. As a result, the intermediate pressure compressor 25 is moved upwards out of the press box 24 by the intermediate pressure cylinder 28.

For example, the intermediate pressure compressor 25 can be moved out of the press box 24 by means of hydraulic separation.

In the press box 31 of the right press wing 21b, in the sixth working cycle, with a second compression step, the intermediate pressure compressor 32 is used for intermediate compression of material that is in the press box 31 by the intermediate pressure compressor 32 from

Intermediate pressure cylinder 35 is moved into the press box 31.

After the sixth work cycle, a new work cycle is started with the first work cycle.

Since the twin press 20 is designed symmetrically, steps in the left press wing 21a, which are carried out in the first work cycle, correspond to work steps in the right press wing 21b, which are carried out in the fourth work cycle, and vice versa. Likewise match

Work steps which are carried out in the left press wing 21a in the second work cycle,

Work steps in the right wing 21b, which are carried out in the fifth cycle, and vice versa. Work steps in the left press wing 21a correspond exactly to those in the third

Work cycle are carried out, work steps in the right wing 21b, the sixth

Work cycle are executed, and vice versa. Corresponding work steps are therefore carried out in the right press wing 21b out of phase by three work cycles to the left press wing 21a.

There are various possibilities for the order in which the intermediate pressure cylinder 28, the finishing pressure cylinder 29 and the cylinder 63 after ejecting the package into them

Starting positions are retracted. Since when the cylinders 28, 29, 63 are retracted, only a small amount of pressure has to be exerted and mainly large volumes of Elydraulik fluid have to be moved, in some exemplary embodiments the retraction is preferably carried out by means of hydraulic coupling, so that return oil is used in an energy-efficient manner to move other hydraulic cylinders without a detour to go to a hydraulic tank.

Therefore, in some exemplary embodiments, the left intermediate pressure cylinder 28 is moved back to its starting position in the sixth working cycle in order to move the right intermediate pressure compressor 32 with the right intermediate pressure cylinder 35 into the right press box 31 in parallel by means of hydraulic separation.

Then the left finished printing cylinder 29 and the cylinder 63 can optionally be moved back to their starting positions in the fifth and / or sixth working cycle, in the sixth working cycle optionally before, during and / or after the return of the left

Intermediate pressure cylinder 28 can be retracted.

In this case, for example, the left finished pressure cylinder 29 can first be retracted until the left finished pressure compressor 26 no longer hinders a closing operation of the door 27. The left finished printing cylinder 26 can then be moved back further and at the same time the door 27 can be closed with the cylinder 63 by means of hydraulic coupling.

In some exemplary embodiments, on the other hand, the left finished pressure cylinder 29 can also be moved back to its starting position in the sixth working cycle, so that the left intermediate pressure cylinder 28 can move the left intermediate pressure compressor 25 into the starting position with the resulting return oil by means of hydraulic coupling. This can be particularly advantageous if the displacement of the left finished printing cylinder 29 is larger than the displacement of the left intermediate printing cylinder 28.

In some exemplary embodiments, there is still enough return oil to close the door 27 with the cylinder 63 by means of hydraulic coupling, or the door 27 is closed with return oil which is produced when the left intermediate pressure cylinder 28 is moved back.

Corresponding considerations can also be made for retracting the right one

Intermediate printing cylinder 35, the right finished printing cylinder 36 and the cylinder 65 are performed and are implemented accordingly in some embodiments. FIG. 18 shows a traverse 66 of an embodiment of the twin press 20, which has two telescopic cylinders 38a and 38b instead of the telescopic cylinder 38. The telescopic cylinders 38a, 38b, 39a and 39b are hydraulic cylinders and are designed here, for example, as two-stage single-acting telescopic cylinders. The telescopic cylinders 38a and 38b are configured to move the filling pressure compressor 23 in the direction of the left pressing wing 21a, while the telescopic cylinders 39a and 39b are configured to move the filling pressure compressor 23 in the direction of the right pressing wing 21b.

The twin press 20 thus has two telescopic cylinders each for the two directions in which the filling pressure compressor 23 can be moved. It can be beneficial if for both

Directions in which the filling pressure compressor 23 can be moved, the same number of hydraulic cylinders, for example telescopic cylinders, is provided. The number of hydraulic cylinders, which is provided for moving the filling pressure compressor 23 in one direction, is not limited to two. In some embodiments, to move the

Filling pressure compressor 23 a hydraulic cylinder can be provided in one direction. In some embodiments, three hydraulic cylinders or more can be provided for moving the filling pressure compressor 23 in one direction.

The telescopic cylinders 38a, 38b, 39a and 39b are attached to the crossmember 66, which is fixedly arranged in the filling box 22 in the middle between the left press wing 21a and the right press wing 21b. One end of the telescopic cylinders 38a and 38b is attached to the crossmember 66 and the other end of the telescopic cylinders 38a and 38b is attached to the left filling pressure plate 23a. One end of the telescopic cylinders 39a and 39b is attached to the crossmember 66 and the other end of the telescopic cylinders 39a and 39b is attached to the right filling pressure plate 23b.

The telescopic cylinders 38a, 38b, 39a and 39b are arranged in recesses in the crossmember 66, so that the telescopic cylinders 38a, 38b, 39a and 39b only protrude slightly from the crossmember 66 in the retracted state.

Pressure transducer plates 67a, 67b and 67c are arranged at each end of the cutouts in the crossmember 66. The pressure transducer plate 67a is designed to receive a force from the telescopic cylinders 38a and 38b and to transmit it to the crossmember 66. The

Pressure transducer plate 67b is designed to receive a force from the telescopic cylinder 39a and to transmit it to the crossmember 66. The pressure transducer plate 67c is designed to receive a force from the telescopic cylinder 39b and to transmit it to the crossmember 66.

The telescopic cylinders 38a, 38b, 39a and 39b are arranged horizontally in FIG. 18. In some exemplary embodiments, the telescopic cylinders 38a, 38b, 39a and 39b can be horizontally and / or vertically offset from one another. 19a to 19c illustrate the operation of the twin press 20 with the telescopic cylinders 38a, 38b, 39a and 39b. In the example shown, the filling pressure compressor 23 is moved from the right press wing 21b to the left press wing 21a. At the same time, a finished pressed package is ejected from the right package chamber 31a. Exemplary hydraulic connections are shown as arrows to illustrate a hydraulic coupling, that is, a positively determined hydraulic oil transfer. The cross member 66 is not shown in FIGS. 19a to 19c for reasons of clarity.

In the following, one side of a double-acting cylinder, which is provided for extending the cylinder, is referred to as the A-pillar and one side of a double-acting cylinder, which is provided for retracting the cylinder, as the B-pillar of the cylinder.

In FIG. 19a, the filling pressure compressor 23 is located on the right press wing 21b and fills the right filling box section 22b. The telescopic cylinders 38a and 38b are retracted and the telescopic cylinders 39a and 39b are extended. The right intermediate pressure compressor 32 is extended, the right finished pressure compressor 33 is also extended and the right door 34 is closed. In the right package chamber 31a is a finished pressed package (not shown). Newly filled material to be pressed (not shown) can be located in the left filling box section 22a.

The filling pressure compressor 23 is now moved away from the right pressure wing 21b to relieve pressure. For this purpose, the telescopic cylinders 38a and 38b are extended somewhat by hydraulic fluid (for example hydraulic oil) with a hydraulic pump 68 from a hydraulic tank into the

Telescopic cylinder 38a and 38b is pumped. The filling pressure compressor 23 is moved in the direction of the left press box 21a and the telescopic cylinders 39a and 39b are pressed together, so that hydraulic fluid is pressed out of the telescopic cylinders 39a and 39b.

Hydraulic fluid, which is pressed out of the telescopic cylinder 39a, the

Telescopic cylinders 38a and 38b supplied. This reduces the volume that has to be pumped into the telescopic cylinders 38a and 38b by the hydraulic pump 68. In some exemplary embodiments, the speed at which the filling pressure compressor 23 is moved can be increased in this way.

Hydraulic fluid which from the pressure relief of the filling pressure compressor 23

Telescopic cylinder 39b is pressed, the B-pillar of the right intermediate pressure cylinder 35 is supplied. In this way, the right intermediate pressure cylinder 35 is retracted in a hydraulic coupling with the telescopic cylinder 39b, thus relieving the pressure of the right intermediate pressure compressor 32. Hydraulic fluid that is pressed out of the A-pillar of the right intermediate pressure cylinder 35 when the right intermediate pressure cylinder 35 moves back becomes the B pillar of the right

Finished printing cylinder 36 supplied. In this way, the right finishing pressure cylinder 36 is retracted in a hydraulic coupling with the right intermediate pressure cylinder 35, thus relieving the pressure on the right finishing pressure compressor 33.

After the pressure relief of the filling pressure compressor 23, the right intermediate pressure compressor 32 and the right final pressure compressor 33, the finished pressed package lies stress-free in the right package chamber 31a. In this state, the right door 34 is not loaded and can be opened.

19b, the right door 34 of the twin press 20 is opened.

The telescopic cylinders 38a and 38b continue to be driven by the hydraulic pump 68 and push the filling pressure compressor 23 in the direction of the left press wing 21a. As described for FIG. 19a, hydraulic fluid which is pressed out of the telescopic cylinder 39a is supplied to the telescopic cylinders 38a and 38b, and hydraulic fluid which is discharged from the

Telescopic cylinder 39b is pressed, the B-pillar of the right intermediate pressure cylinder 35 is fed to further reverse the right intermediate pressure compressor 32.

Hydraulic fluid that is pressed out of the right intermediate pressure cylinder 35, on the other hand, is supplied to the B-pillar of the right door cylinder 65. In this way, the right door 34 is opened in hydraulic coupling with the right intermediate pressure cylinder 35. When the right door 34 is opened, the package can be ejected from the right package chamber 31a.

In Fig. 19c, the package is ejected from the right package chamber 31a.

The telescopic cylinders 38a and 38b continue to be driven by the hydraulic pump 68 and continue to push the filling pressure compressor 23 in the direction of the left pressing wing 21a. As described for FIGS. 19a and 19b, hydraulic fluid which is thereby pushed out of the telescopic cylinder 39a is supplied to the telescopic cylinders 38a and 38b, and hydraulic fluid which is discharged from the

Hydraulic fluid that is pressed out of the right intermediate pressure cylinder 35, however, is not supplied to a hydraulic cylinder, but rather flows into one, for example

Hydraulic tank back.

At the same time, the right finishing cylinder 36 is extended further by a hydraulic pump 69 hydraulic fluid from a hydraulic tank into the A-pillar of the right finishing cylinder 36 pumps. The right final pressure compressor 33 is moved into the right package chamber 31a and pushes the package through the door 34 out of the package chamber 31a.

Hydraulic fluid, which is pressed out of the B-pillar of the right finishing cylinder 36, is also supplied to the telescopic cylinders 38a and 38b. In some exemplary embodiments, this can further reduce the volume that flows from the hydraulic pump 68 into the

Telescopic cylinder 38a and 38b must be pumped.

Some exemplary embodiments have corresponding hydraulic connections between the telescopic cylinders 38a, 38b, 39a and 39b, the left intermediate pressure cylinder 28, the left finished printing cylinder 29 and the left door cylinder 63 in order to move the filling pressure compressor 23 in the direction of the right pressing wing 21b and at the same time a completely pressed one Eject the package through the left door 27 from the left package chamber 24a.

Similarly, further hydraulic couplings can be implemented in some exemplary embodiments. For example, hydraulic fluid coming from the A pillar of the right

Intermediate pressure cylinder 35 is pushed while a package is being discharged from the right package chamber 31a, as shown in Fig. 19c, to the A-pillar of the right finished-pressure cylinder 36 to reduce a volume from the hydraulic pump 69 into the A-pillar of the right finishing cylinder 36 must be pumped. In such embodiments, the hydraulic coupling from the B-pillar of the right finishing cylinder 36 to the

Telescopic cylinders 38a and 38b are omitted.
