Description

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 are used, for example, in scrap yards, in body pressing plants, in 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 capacity.

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 which is opposite the filling pressure compressor.

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

In the case of packaging presses for two-dimensional compression, it is known that the intermediate pressure compressor can be dispensed with. 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 finished pressure compressor and pushing the package through the hydraulic door using the finished 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 16.

Further aspects and features of the present invention result from the dependent claims, the attached drawing and the following description of preferred 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 comprise, for example, a wide range of light to 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. The compressor can be actuated, for example, by a hydraulic system, for example a hydraulic cylinder, which presses the compressor in the direction of the 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 on 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 in the second press box by the compressor with the pressure plate and the wear plate is pressed 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, then it moves, for example, towards the first press box and at the same time away from the second press box until it engages in the first press box. 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 embodiments, the first direction and the second direction are opposite to each other.

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. If, on the other hand, a package is to be produced by two-dimensional compression, the press wing can be designed without an intermediate pressure compressor.

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, for example, be provided to guide 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 being 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 portion is located under an opening of the press box through which the compressor engages the press box, and the package is ejected transverse to the direction in which the compressor engages the press box.

In some embodiments, the parcel is then guided by the guide section when it is ejected, and the compressor is not required to guide the parcel when it is 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, in some exemplary embodiments of the packaging press according to the invention, several, for example two or three, work steps can be carried out in parallel.

For example, while a first package produced in the first press wing is ejected from the first press box by opening a door of the first press box in a first work step and / or in a second work step the first packet with a pre-pressure compressor of the first press wing through the door from the first Press box is pushed, the production of a second package in the second press wing can be started 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 press box can be closed and / or the final pressure compressor of the first press wing can be moved back while the compressor continues 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 carry out a first compression step, that is to say 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 exemplary embodiments, the packaging press further comprises a material feed, the material feed selectively loading material into the first filling box section and the second filling box section.

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 in a is actuated in the first direction, moved through the first filling box section to the first press box and, if it is operated in a second direction, moved through the second filling 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 can be moved vertically against the housing of the filling box with screw connections, with shims, with perforated wedges or in a similar manner.

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 can be advantageous to set a play of a few tenths of a millimeter between the shearing 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 can be set between a shear knife on a side of the compressor facing the second filling box section and a cutting edge of a press box arranged on the second filling box section .

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 system and / or another drive device) that ejects 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 of the package hydraulically couples 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 in such a way that the package is ejected with a final pressure compressor through a door from a press box, the compressor, the final pressure compressor and the door being 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 work 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, are carried out in parallel (at least partially) in time.

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 operating the compressor in a second direction so that it engages the second press box, the package being ejected from the first press box while the compressor is being operated in the second direction.

The method or the work steps described herein can be implemented in a controller for the packaging press, e.g. B. as instructions that are executed by a computer, processor, microcontroller or the like 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 so 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 follow with reference to 1a and 1b or in the following also on the 2nd to 7 .

In 1 and 1b is a packaging press 1 represented according to the prior art.

The packaging press 1 has a funnel 2nd (only in 1b) , a filling box 3rd , a press box 4th , a filling pressure compressor 5 , a filling pressure cylinder 6 , a clipper 7 , a cutting edge 8th and strokes 9 for the filling pressure compressor 5 . The packaging press also includes 1 an intermediate pressure compressor 10 , an intermediate pressure cylinder 11 , Attacks 12th for the intermediate pressure compressor 10 , a final pressure compressor 13 , a finished printing cylinder 14 , a parcel compartment 15 , a door 16 as well as a scraper 17th .

The packaging press 1 is placed over the funnel by means of a crane, a conveyor belt, a slide or a scale 2nd loaded. The funnel 2nd flows into the filling box 3rd so that material to be pressed into the funnel 2nd is filled in the filling box 3rd falls.

The filling box 3rd is laterally delimited by two side walls, an opening to the press box 4th that is at one end of the fill box 3rd borders, and a pressure plate of the filling pressure compressor 5 . Below is the fill box 3rd bounded by a floor.

The inflation pressure compressor 5 is on the press box 4th opposite end of the fill box 3rd arranged and is from the inflation cylinder 6 , a hydraulic cylinder, moved horizontally. The inflation pressure compressor 5 comprises a pressure plate with which the compressive forces of the filling pressure compressor 5 be transferred to the material to be pressed, as well as a wear plate (not shown), which wear the filling pressure compressor 5 reduced.

Material to be pressed that is in the filling box 3rd is from the filling pressure compressor 5 by extending the filling pressure cylinder 6 in the press box 4th pressed. Excess material of the material to be pressed, which is above the pressure plate of the filling pressure compressor 5 protrude between the blades 7 , which is on the upper edge of the pressure plate of the filling pressure compressor 5 is attached, and the cutting edge 8th that are at the top of the opening to the press box 4th is arranged, separated.

The adjustable stops 9 on the filling pressure compressor 5 ensure that the inflation pressure compressor 5 one to an end wall of the press box 4th plane-parallel end position reached. The distance between the pressure plate of the inflation compressor 5 in the end position and the opposite end wall of the press box 4th corresponds to the width of the package to which the material to be pressed is pressed.

The attacks 9 can be aligned with shims as required. In this way you can set how far the filling pressure compressor 5 in the press box 4th intervenes. In some embodiments, it is advantageous to use the stops 9 so that the wear plate of the filling pressure compressor 5 the opening of the press box 4th flush with the inner wall of the press box 4th completes, whereby a slight play, for example of a few tenths of a millimeter, can prevent the final pressure compressor 13 when approaching the wear plate of the filling pressure compressor 5 hits and the pressing process is blocked.

Material to be pressed that is in the press box 4th is located vertically by the intermediate pressure compressor 10 pressed to a height that corresponds to the height of the package.

The intermediate pressure compressor 10 is from the intermediate pressure cylinder 11 , a hydraulic cylinder, moves and includes a pressure plate with which the pressure forces of the intermediate pressure compressor 10 transferred to the material to be pressed, as well as a wear plate (not shown), which wear the intermediate pressure compressor 10 reduced.

In addition, the intermediate pressure compressor 10 with stops 12th Mistake. The attacks 12th are relined with shims and occur when the intermediate pressure compressor reaches a plane-parallel end position 10 with a housing of the packaging press 1 in contact. The end position, and thus the height of the package, can be set with the shims.

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

The finished pressure compressor 13 is from the finished printing cylinder 14 , a hydraulic cylinder. The finished pressure compressor 13 includes a pressure plate with which the compressive forces of the final pressure compressor 13 be transferred to the material to be pressed, and which is adapted to the cross section of the package, and a wear plate (not shown), which wear the finished pressure compressor 13 reduced.

The finished 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 4th in which the finished pressed package is located is the package chamber 15 . The parcel chamber 15 is vertical from a bottom and from the pressure plate of the intermediate pressure compressor 10 limited. The parcel chamber is on the side 15 from the pressure plate of the filling pressure compressor 5 and the opposite end wall of the press box 4th as well as from the pressure plate of the final pressure compressor 13 and the door opposite it 16 limited.

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

A packaging press is required to press the material to be pressed into a package 1 eight work cycles according to the state of the art.

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

The first compression step takes place in the second cycle. The inflation pressure compressor 5 presses in the filling box 3rd material to be pressed horizontally into the press box for pre-compression 4th .

Material to be pressed over the filling box 3rd protrudes from the shear knife 7 at the cutting edge 8th separated.

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

The inflation pressure compressor 5 remains in the forward position after the second work cycle.

The workstakes are now referenced to the 2nd to 7 described.

In 2nd is the packaging press 1 after the second work cycle. The inflation pressure compressor 5 has come up. The intermediate pressure compressor 10 and the final pressure compressor 13 have returned. The door 16 is closed.

The funnel 2nd can still be loaded; the filled material is from the filling pressure compressor 5 stopped and only falls into the filling box 3rd when the inflation pressure compressor 5 is reduced in a later work cycle. The filling box 3rd is therefore fed indirectly.

The second compression 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 too 10 remains in the forward position.

In 3rd is the packaging press 1 after the third work cycle. The inflation pressure compressor 5 and the intermediate pressure compressor 10 have brought up. The finished pressure compressor 13 drove back. The door 16 is closed.

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

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

The package is from the pressure plates of the inflation compressor 5 , of the intermediate pressure compressor 10 and the final pressure compressor 13 as well as from Front wall and bottom of the press box 4th and the door 16 enclosed.

In 4th is the packaging press 1 after the fourth work cycle. The inflation pressure compressor 5 and the intermediate pressure compressor 10 have brought up. The finished 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.

The filling pressure compressor is depressurized in the fifth cycle 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 will the door 16 on the finished pressure compressor 13 opposite side of the parcel chamber 15 opened by means of hydraulic separation. Hydraulic separation means that the pressure relief of the intermediate pressure compressor 10 and opening the door 16 via independent hydraulic systems.

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

In 5 is the packaging press 1 after the fifth work cycle. The inflation pressure compressor 5 and the intermediate pressure compressor 10 are driven up, but do not exert any pressure on the package. The finished pressure compressor 13 has moved up to the desired package length, but does not exert any pressure on the package either. The package lies stress-free in the package chamber 15 . The door 16 is opened.

In the sixth work cycle, the package is further ancestor of the final pressure compressor 13 through the open door 16 from the parcel chamber 15 pushed out.

The door 27 and the door 34 can also on opposite sides of the twin press 20 be arranged so that manufactured packages from the press wings 21a , 21b be expelled in opposite directions. The latter is in 8th shown.

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

The press box 24th of the left wing 21a and the press box 31 of the right wing 21b are mechanical here with the common filling box 22 connected.

The press box 24th of the left wing 21a and the press box 31 of the right wing 21b can be arranged parallel to each other; in this embodiment, for example, they are arranged linearly, with the common filling box 22 between the press box 24th and the press box 31 is arranged.

In the middle of the common filling box 22 is the filling pressure compressor 23 arranged. The inflation pressure compressor 23 has the left filling pressure plate 23a and the right filler plate 23b . This will make the common filling box 22 in the left filling box section 22a and the right fill box section 22b divided.

The inflation pressure compressor 23 presses material to be pressed, which is in the left filling box section 22a with the left filling pressure plate 23a in the press box 24th of the left wing 21a , and presses material to be pressed, which is in the right filling box section 22b with the right filling pressure plate 23b in the press box 31 of the right wing 21b .

The inflation pressure compressor 23 is operated by a hydraulic telescopic cylinder 38 to the left wing 21a pressed, which is concentric with a back of the left filler plate 23a connected is.

The inflation pressure compressor 23 is also powered by two hydraulic telescopic cylinders 39a and 39b to the right wing 21b pressed with a back of the right filler plate 23b are connected laterally offset.

In 9 is a side view of a twin press according to the invention 20 illustrated.

The telescopic cylinder 38 as well as the telescopic cylinders 39a and 39b are on a common mechanical support 40 , a so-called traverse 40 , appropriate. The traverse 40 is relative to the common filling box 22 fixed.

When extending the telescopic cylinder 38 or the telescopic cylinder 39a and 39b shifts due to a mechanical connection of the left filling pressure plate 23a and the right filler plate 23b and due to the fixed arrangement of the telescopic cylinder 38 and the telescopic cylinder 39a and 39b on the traverse 40 both the left filler plate 23a as well as the right filling pressure plate 23b parallel to the connecting line of the press boxes 24th , 31 of the left wing 21a and the right press wing 21b .

The mechanical connection between the left filling pressure plate 23a and the right filler plate 23b is here, among other things, through the upper connector 23c and the lower connectors 23d provided so that the filling pressure compressor 23 together with the left filling pressure plate 23a and the right filler plate 23b shifts.

The top connector 23c and the lower connectors 23d serve an additional mechanical strength during the movement of the filling pressure compressor 23 .

The top of the inflation compressor 23 includes two sections through the top connector 23c are connected via a longitudinal groove. The top connector 23c is fastened with self-tapping screws, the heads of which are flush with the top of the filling pressure compressor 23 lock off so that the self-tapping screws do not come into contact with scrapers 47 , 48 get caught. The self-tapping screws are arranged in the groove. The forces that occur during compression are not generated via the self-tapping screws, but via cross-sectional areas of the upper connecting piece that are in contact with one another 23c and the top portions of the inflation compressor 23 transfer. The self-tapping screws are only used to fasten the upper connector 23c , but not the power transmission.

The lower connectors 23d are as two square bars 23d executed. They are also over a groove with sections of the filling pressure compressor 23 connected and fastened with a screw connection 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 connecting pieces 23d and cross-sectional areas of sections of the filling pressure compressor in contact therewith 23 . Accordingly, the screw connection is not used for power transmission, but only for fastening the lower connecting pieces 23d .

The inflation pressure compressor 23 and the filler plates 23a and 23b are not provided with adjustable stops in this embodiment, which ensure that a plane-parallel end position is reached. Instead, an end position is established between the working pistons of the telescopic cylinders using thin washers 38 , 39a such as 39b and associated baffle plates.

Again 9 can also be removed is a floor 41 of the press box 31 of the right wing 21b opposite a floor section 42b the right filler box section 22b shifted down.

In the right part of 9 is the parcel chamber 31a illustrated, i.e. the section of the press box 31 in which a finished pressed package lies.

Due to the vertical offset of the floor 41 of the press box 31 opposite the bottom section 42b the right filler box section 22b a finished pressed package is guided when it is ejected. This can prevent the package from becoming wedged when it is ejected, thereby preventing it from being ejected.

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 floor can 41 of the press box 31 and the bottom section 42b the right Filling box section 22b for example, be 40 millimeters.

Because of the vertical offset between the floor 41 of the press box 31 of a press wing 21b and the bottom section 42b the right filler box section 22b becomes the filling pressure plate 23b not required to guide the package when it is ejected.

Therefore, parallel to a step in which the intermediate pressure cylinder 35 and the finished printing cylinder 36 of the right wing 21b be relieved, the telescopic cylinder 38 be extended by the left pressure plate 23a material to be pressed into the press box 24th of the left wing 21a presses.

Because of the mechanical connection 23c , 23d between the left filling pressure plate 23a and the right filler plate 23b the right filling pressure plate also moves 23b and pushes part of the telescopic cylinder 39a , 39b in their starting position.

In the present exemplary embodiments, return oil is obtained from the telescopic cylinders 39a and 39b is pressed, not fed back into a hydraulic tank, but by means of hydraulic coupling, i.e. an inevitable predetermined oil transfer, to open the door 34 and to eject the package through the pre-press compressor 33 used.

Accordingly, it is possible in the present case that, parallel to a work step, in the intermediate pressure cylinder 28 and finished printing cylinder 29 of the left wing 21a be relieved, the telescopic cylinder 39a and 39b be extended by the right pressure plate 23b material to be pressed into the press box 31 of the right wing 21b to press.

Because of the mechanical connection 23c , 23d between the left filling pressure plate 23a and the right filler plate 23b the left filling pressure plate also shifts 23a and pushes part of the telescopic cylinder 38 in their starting position.

In addition, in the present exemplary embodiment, return oil is obtained from the telescopic cylinder 38 is pressed, not fed back into a hydraulic tank, but by means of hydraulic coupling to open the door 27 and to eject a package through the pre-press compressor 26 used.

In this way, the number of packets produced per unit of time can be compared to the prior art according to 1 to 7 be reduced.

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

In addition, the twin press 20 a wiper 47 , the material to be pressed, which is removed when the filling pressure compressor is moved away 23 from the left wing 21a on the filling pressure compressor 23 lies in the left filling box section 22a wipes, as well as a wiper 48 , the material to be pressed, which is removed when the filling pressure compressor is moved away 23 from the right wing 21b on the filling pressure compressor 23 lies in the right filling box section 22b strips off.

Since in the present embodiment the filling pressure compressor 23 from the left wing 21a is moved away while a finished pressed package from the final pressure compressor 26 from the press box 24th of the left wing 21a material to be pressed could be ejected into the left filling box section 22a fall off while the finished pressure compressor 26 drove up.

To prevent material from entering the press box 24th behind the advanced compressors 26 falls and a retraction of the final pressure compressor 26 is hampered in the present embodiment, the final pressure compressor 26 of sufficient length so that even when the pre-press compressor is brought up 26 no material behind the final pressure compressor 26 can reach.

For example, the length of the final pressure compressor 26 at least the length of the press box 24th of the left wing 21a amount as in 8th shown.

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

In 10 and 11 are exemplary embodiments for loading the twin press according to the invention 20 illustrated.

During a packaging press 1 according to the prior art, for example via a conveyor belt and a funnel 2nd is loaded, the material flow constant over the sole Filling box 3rd in the sole press box 4th runs, material to be pressed in a twin press according to the invention 20 over two filling box sections 22a , 22b in two press boxes 24th , 31 promoted. Depending on the position of the filling pressure compressor 23 material to be pressed is either in the left filling box section 22a or in the right filling box section 22b filled to in the appropriate press box 24th or 31 to be pressed.

The inflation pressure compressor 23 can be kept in a vertical floating state in some embodiments using trapezoidal wear plates and can only be guided horizontally. As a result, less wear and tear can occur in some exemplary embodiments.

The following is an exemplary method according to the invention for packaging deformable material with a packaging press, such as the twin press explained above 20 , described.

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

Because the work cycles of the twin press 20 can be executed cyclically, the work cycles can be numbered for any work cycle. For better comprehensibility, the numbering of the work cycles is chosen here so that from the first to the sixth work cycle a package in the left press wing 21a will be produced.

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

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

The inflation pressure compressor 23 is from the left wing 21a moved away so that a maximum filler section 22a between the left wing 21a and the left filler 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.

In the left filling box section 22a filled material remains on the floor 42 of the filling box 22 between the left wing 21a and the left filler plate 23a lie.

In the first work cycle, the finished printing cylinder 29 and the cylinder 63 returned to their starting positions. That means that the left finished pressure compressor 26 from the finished printing cylinder 29 from the left press box 24th pulled out and the door 27 from the cylinder 63 is closed.

The finished pressure compressor 26 is first driven back a section alone until it closes the door 27 not affected.

The inflation pressure compressor 23 but by extending the telescopic cylinder 38 also from the right wing 21b moved away.

The right fill box section 22b between the right filling pressure plate 23b and the press box 31 of the right wing 21b free and can now be loaded with material to be pressed directly.

It can happen that on the inflation compressor 23 between the wipers 48 and the right wing 21b Material to be pressed lies, for example, because it is fed into the twin press via a material feed 20 has been filled during the filling pressure compressor 23 in the press box 31 of the right wing 21b intervened, or because it was moving the inflation compressor 23 towards the right wing 21b by a shearing action between the shear knife 45 and the cutting edge 46 has been separated.

This material is used when moving the inflation compressor 23 towards the left wing 21a from the scraper 48 in the right filling box section 22b between the right filling pressure plate 23b and the press box 31 stripped.

When moving the filling pressure compressor 23 to the left wing 21a become the telescopic cylinders 39a and 39b between the filling pressure compressor 23 and the trusses 40 pressed together. Hydraulic fluid, for example hydraulic oil, hereinafter called return oil, from the telescopic cylinders 39a and 39b pressed.

The return oil is not returned to a hydraulic tank unused, but rather to eject a package from the press box 31 of the right wing 21b utilized.

The intermediate pressure cylinder is depressurized to eject the package 35 and the finishing cylinder 36 so that the package is tension-free in the press box 31 lies.

To eject the package, the return oil from the telescopic cylinders 39a and 39b the door 34 through the cylinder 65 opened and the final pressure compressor 33 through the finished printing cylinder 36 further into the press box 31 moved in so that the finishing cylinder 36 the package through the door 34 from the press box 31 pushes out. The package is placed at a vertical offset between a floor 41 of the press box 31 and the right bottom section 42b of the filling box 22 led so that it does not wedge and hinder the ejection.

In addition, the package is ejected from the pressure plate of the intermediate pressure compressor 32 led so that it does not wedge.

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

15a and 15b illustrate the twin press 20 after the third cycle.

That in the press box 24th The material is transported with the vertically arranged intermediate pressure compressor 25th from the intermediate pressure cylinder 28 is moved, pressed to a predetermined package height.

This is a second compression step for the intermediate compression of the material to be pressed. The material is in a second direction, namely the working direction of the intermediate pressure compressor 25th , condensed.

The intermediate pressure compressor 25th includes adjustable stops 30th that can be used to ensure that the intermediate pressure compressor 25th reached an end position in which a pressure plate of the intermediate pressure compressor 25th plane-parallel to a bottom of the press box 24th is.

The intermediate pressure compressor 25th is moved a longer distance than an intermediate pressure compressor 10 a parcel press 1 according to the state of the art, because the bottom of the press box 24th opposite the left section of the floor 42b of the filling box 22 is offset downwards so that a parcel can be guided at the vertical offset formed in this way and does not become wedged.

The inflation pressure compressor 23 , the final pressure compressor 26 and the door 27 are not moved in the third cycle. Accordingly, the filling pressure compressor intervenes 23 still in the press box 24th one, the final pressure compressor 26 stays outside of the press box 24th and the door 27 remains closed.

The intermediate pressure compressor 32 of the right wing 21b can, for example, in the third cycle by retracting the intermediate pressure cylinder 35 up from the press box 31 be brought out.

The finished pressure compressor 33 and the door 34 are not moved in the third cycle. Accordingly, the final pressure compressor remains 33 in the press box 31 drove in and the door 34 remains closed.

In a fourth work cycle, the finished printing cylinder 29 brought up. The final pressure compressor 26 of the left wing 21a in the press box 24th drove in.

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

The finished pressure compressor 26 is in a horizontal, transverse to the working direction of the filling pressure compressor 23 arranged guide channel in the press box 24th driven in until it reaches a predetermined position and is switched off, for example, by a pressure switch.

That in the press box 24th pre-pressed material is in a third direction, namely in the working direction of the final pressure compressor 26 , pressed to a predetermined package length. This is a third compression step for final compression.

The material to be pressed now lies in the press box as a finished pressed package with the predetermined dimensions 24th of the left wing 21a . The section of the press box 24th in which the finished pressed package is located is the package chamber 24a .

The inflation pressure compressor 23 , the intermediate pressure compressor 25th and the door 27 are not moved in the fourth cycle. Accordingly, the Inflation pressure compressor 23 still in the press box 24th one, the intermediate pressure compressor 25th is still in the press box from above 24th drove in and the door 27 is still closed.

The finished pressure compressor 33 becomes the press box in the fourth work cycle 31 of the right wing 21b pulled out and the door 34 will be closed. The intermediate pressure compressor 32 is not moved in the fourth work cycle and accordingly remains upwards out of the press box 31 pulled out.

In a fifth work cycle, the pressed package is removed from the press box 24th of the left wing 21a pushed out.

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

The finished pressed package is in the package chamber at the beginning of the fifth cycle 24a of the left wing 21a from the left filler plate 23a , the pressure plate of the intermediate pressure compressor 25th , the pressure plate of the final pressure compressor 26 , the door 27 and a floor and the bulkhead 24b of the press box 24th surround.

So that the package after opening the door 27 from the final pressure compressor 26 from the press box 24th can be ejected, the package is in a de-energized state.

• Es wird eine Druckentlastung des Zwischendruckzylinders 28 und des Fertigdruckzylinders 29 durchgeführt, die Teleskopzylinder 39a und 39b werden ausgefahren, die Tür 27 wird geöffnet und der Fertigdruckverdichter 26 wird weiter in den Presskasten 24 hineingefahren und schiebt so das Paket durch die Tür 27 aus dem Presskasten 24.

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

• There is a pressure relief of the intermediate pressure cylinder 28 and the finishing cylinder 29 carried out the telescopic cylinder 39a and 39b are extended, the door 27 is opened and the final pressure compressor 26 will continue in the press box 24th drove in and pushes the package through the door 27 from the press box 24th .

The pressure relief of the intermediate pressure cylinder 28 and the finishing cylinder 29 is provided so that the package is stress-free in the package chamber 24a lies.

By extending the telescopic cylinder 39a and 39b becomes the inflation pressure compressor 23 from the left wing 21a moved away.

On the one hand, this is also provided so that the package is free of tension in the package chamber 24a lies.

On the other hand, this can cause material to be pressed that is in the right filling box section 22b between the wipers 48 and the press box 31 of the right wing 21b is from the filling pressure compressor 23 already in the press box 31 transported and pre-compressed in a first compression step while the package is out of the press box 24th of the left wing 21a is expelled.

In addition, material to be pressed is placed between the left press wing 21a and the wiper 47 on the filling pressure compressor 23 lies when moving the filling pressure compressor 23 to the right wing 21b on the scraper 47 in the left filling box section 22a between the press box 24th of the left wing 21a and the left filler plate 23a stripped.

To prevent the package from being pushed out in the press box 24th wedged and preventing ejection, it must be guided when ejecting.

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

Because the inflation pressure compressor 23 the twin press 20 while ejecting the package from the press box 24th is moved away, the filling pressure compressor stands 23 not available to guide the package during ejection.

The twin press 20 therefore has a guide portion in the form of a vertical offset between a bottom of the press box 24th and the left bottom section 42a of the filling box 22 on. The bottom of the press box 24th , and thus the guide channel in which the final pressure compressor 26 is moved is against the left section of the floor 42a of the filling box 22 shifted down.

This vertical offset is dimensioned sufficiently so that the package when ejecting without a stabilizing effect of the left filling pressure plate 23a can be guided and not wedged.

The package is also discharged from the pressure plate of the intermediate pressure compressor when it is ejected 25th led so that it does not wedge.

By extending the telescopic cylinder 39a and 39b and moving the inflation compressor accordingly 23 becomes the telescopic cylinder 38 pressed together.

Hydraulic fluid, for example hydraulic oil (but can also be any other fluid), hereinafter called return oil, which comes from the telescopic cylinder 38 is pressed, is used to connect the door by means of hydraulic coupling 27 With the cylinder 63 to open and the final pressure compressor 26 with the finished printing cylinder 29 further into the press box 24th to drive in.

This will make the package from the pre-press compressor 26 through the door 27 from the press box 24th pushed out. 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 wing 21b stay out of the press box in the fifth cycle 31 pulled out, and the door 34 remains closed.

The work steps in the fifth cycle in the right wing 21b by operating the telescopic cylinder 39a and 39b are carried out, correspond to work steps in the second work cycle in the left wing 21a by operating the telescopic cylinder 38 be carried out.

The intermediate pressure cylinder is in the sixth work cycle 28 moved back to its original position. This will make the intermediate pressure compressor 25th from the intermediate pressure cylinder 28 from the press box 24th extended upwards.

For example, the intermediate pressure compressor 25th by means of hydraulic separation from the press box 24th be brought out.

In the press box 31 of the right wing 21b takes place in the sixth cycle with a second compression step with the intermediate pressure compressor 32 an intermediate compression of material that is in the press box 31 by the intermediate pressure compressor 32 from the intermediate pressure cylinder 35 in the press box 31 is driven in.

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

Because the twin press 20 Is carried out symmetrically, work steps correspond to the left wing 21a which are carried out in the first work cycle, work steps in the right wing 21b which are carried out in the fourth work cycle, and vice versa. Likewise, work steps correspond to those in the left press wing 21a are carried out in the second cycle, steps in the right wing 21b which are carried out in the fifth work cycle, and vice versa. Steps in the left wing are the same 21a which are carried out in the third work cycle, work steps in the right wing 21b which are carried out in the sixth work cycle, and vice versa.

Corresponding work steps are in the right wing 21b by three work cycles to the left wing 21a out of phase.

There are various options for the order in which the intermediate pressure cylinder 28 , the finished printing cylinder 29 and the cylinder 63 be returned to their original positions after the package has been ejected. Because when the cylinders retract 28 , 29 , 63 only a little pressure is exerted and mainly large volumes of hydraulic 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 having to go through a hydraulic tank.

Therefore, in some embodiments, the left intermediate pressure cylinder 28 returned to its starting position in the sixth work cycle in order to use hydraulic separation to parallel the right intermediate pressure compressor 32 with the right intermediate pressure cylinder 35 in the right press box 31 to drive.

Then the left finishing cylinder 29 as well as the cylinder 63 optionally in the fifth and / or in the sixth work cycle are moved back to their starting positions, in the sixth work cycle optionally before, during and / or after the return of the left intermediate pressure cylinder 28 can be reversed.

For example, the left finished printing cylinder can be used first 29 alone until the left finished pressure compressor 26 a closing process of the door 27 no longer disabled. Then the left finishing cylinder 26 retracted further and at the same time the door by means of hydraulic coupling 27 with the cylinder 63 getting closed.

In some embodiments, however, the left finished printing cylinder can 29 in the sixth work cycle to be returned to its starting position, so that the left intermediate pressure cylinder with the resulting return oil by means of hydraulic coupling 28 the left intermediate pressure compressor 25th can move to the starting position. This can be particularly advantageous if the displacement of the left finished printing cylinder 29 is larger than the displacement of the left intermediate pressure cylinder 28 .

In some exemplary embodiments, there is still enough return oil to use hydraulic coupling to open the door 27 with the cylinder 63 close or the door 27 is closed with return oil, which when returning the left intermediate pressure cylinder 28 arises.

Corresponding considerations can also be made for retracting the right intermediate pressure cylinder 35 , the right finishing cylinder 36 and the cylinder 65 are carried out and are implemented accordingly in some exemplary embodiments.
