Abstract

In order to be able to attach an automatic rear filling device (20) to a vertically acting box baling press (1), which does not increase the height requirement for such an automated, vertical box baling press (1) too much, and at the same time allows batch operation , a collecting trolley (SW) filled with loose material to be pressed (P) is automatically lifted by means of a suitable lifting device (20) and tipped into a storage container (21) on the rear (2.2) of the box baler (1), for example , and from there, by means of a supply slide (24), it is pushed obliquely upwards in the feed direction (24 ') through a filling opening (2.2a) into the interior of the press box (2).

Description

I. Field of application

The invention relates to box baling presses in which the press material is pressed by the press ram against a fixed abutment, namely the end wall of the press box. The invention relates specifically to vertical box baling presses in which the ram moves up and down, usually in the vertical, and presses the material to be pressed against the bottom of the press box, which is open at the top and only closed by the ram.

II. Technical background

The one or both press rams acting in parallel are mostly actuated by means of hydraulic cylinders.

Such vertically acting box baling presses are often used when there is a small amount of material to be pressed.

Often, the filling and emptying takes place from the front of the baler, in that there is a closable filling opening in the upper area of the front wall through which the loose material to be pressed - for example empty cardboard boxes or empty plastic bottles or beverage cans - is manually filled into the press box, when the ram is in the upwardly retracted starting position, namely above the filling opening.

If after a certain number of pressing strokes a bale has built up to the desired height in the press box, it can be removed via the also closable removal opening under the filling opening in the front wall, whereby the produced and the bale still in the press box is carried out.

In order to reduce the manual effort and also to increase the throughput of such a vertically acting box baler, it is known to fill such box presses automatically by a conveyor belt transporting loose pressed material placed on it to the filling opening and throwing it through it into the press box when the ram is in its initial position above. The conveyor belt usually runs at an incline from the bottom upwards towards the filling opening so that the loose filling material can be conveniently placed on the low-lying end of the conveyor belt.

Since such an automatic filling device would be in the way when emptying the box baler if the filling opening and thus also the filling device are still on the front of the baler, in these cases the filling opening is usually on the front arranged opposite rear side.

However, such a conveyor belt requires a lot of floor space in addition to the rest of the vertical box baling press, the main advantage of which is that it requires very little floor space, which means that its main advantage is lost. In addition, a vertically acting box baler equipped with it can no longer be set up at a short distance in front of a wall.

In addition, there is also the fact that frequently - especially in the case of cardboard boxes or empty beverage containers as pressed material - the pressed material is collected away from the baling press in collection cars open at the top, and the filled collection cars then pushed to the baler. Then the collection trolley should be able to be emptied as completely as possible into the baler in order to have the empty collection trolley immediately available again.

The material to be pressed is therefore produced in batches at the baling press.

III. Presentation of the invention a) Technical task

It is therefore the object of the invention - especially with batchwise pressing material - to provide a vertically acting box baler with an automatic filling device that requires the smallest possible footprint, simple, so that it can be produced inexpensively and nevertheless functionally reliably and only one as possible requires little manual effort for operation, as well as a corresponding operating method for operating such a baling press.

b) Solution of the task

This object is achieved by the features of claims 1 and 12. Advantageous embodiments emerge from the subclaims.

A generic vertically acting box baler comprises a press box with a bottom and from it - mostly from its peripheral edges - upward, mostly vertical, protruding side walls that form the press box, and a press ram that can be moved up and down in the press box, which is usually by means of an or several parallel acting, mostly hydraulically operated, working cylinders can be moved with great force.

The bottom and thus the inner horizontal cross-section of the press box is mostly approximately rectangular, so that there are four side walls, which are arranged in a square to one another when viewed from above, and which are mostly adjacent to one another adjoin, i.e. continuously surround the press box in the horizontal circumferential direction, the side walls not running exactly parallel to one another, but rather a slightly increasing distance from one another from back to front, towards the removal opening, in order to facilitate removal of the finished bale.

However, other forms of horizontal cross-sections of the press box are also possible, for example a round cross-section with the result that a single cylindrical side wall is then present, which, however, should also be included in the mention of several side walls used here.

One of the side walls, which is referred to as the front wall, is usually designed as a completely openable removal door for removing the finished bale, and in its upper part, in particular its upper half, there is a front filling opening that can be closed by a filling flap.

The upper edge of the filling opening is usually below the pressing surface, the underside of the press plunger retracted into its upper end position, the starting position. The lower edge of the filling opening is usually still above the height of the upper edge of the removal opening, but no more than 10 cm, better not more than 5 cm below this height.

If there is an automatic - i.e. at least motorized and controlled manually or by means of a controller - filling device, this filling opening is usually not located in the front wall, but in one of the other side walls, usually in the rear wall opposite the front wall. By means of such an automatic filling device, the loose pressed material deposited on or in it is not only transported to the filling opening, but also conveyed through it into the press box, and for this purpose pushed through the filling opening by the automatic filling device.

In addition, there is a control system - usually electrical or electronic - which controls the entire baling press, in particular all moving parts of the baling press.

This control is supplemented by a corresponding sensor system, which in particular detects the open position or closed position of the doors or flaps closing the openings of the press box, the position of the press ram and possibly all other relevant physical parameters on the baler.

According to the invention , in such a vertically acting box baler, this object is achieved in that the automatic filling device is initially designed for batch-wise automatic filling of this baler, that is to say its press box.

As a result, the pressing material produced in batches can be pressed very quickly by means of the baling press according to the invention.

(Volume of storage container :)

In particular, this automatic filling device comprises a storage container for receiving loose pressed material, the volume of which - with a variable volume its maximum volume - is sufficient for receiving a complete batch - the maximum volume of which is predetermined - of, in particular loose, pressed material. The specified batch volume is usually the volume of a collection vehicle in which the loose pressed material is collected at the location where it is produced.

This has the advantage that the entire contents of a filled collection vehicle can be emptied automatically into this automatic filling device at once and therefore very time-saving.

For this purpose, the filling device, in particular its storage container, preferably has a filling opening, in particular in the upper area, so that the loose material to be pressed can fall into the storage container from above due to gravity. In particular, such a filling opening is formed in the upper side of the storage container, wherein as the simplest solution the upper side can be completely open as a filling opening.

It is precisely through such a large filling opening that the storage container can be loaded very easily and quickly.

So that the loose material to be pressed can be brought from the storage container to the filling opening of the pressing box as easily as possible, the storage container is connected to the filling opening or can at least be connected to it.

This does not necessarily require a contact between the storage container and the filling opening, but only that the storage container and in particular its dispensing opening in the direction of the filling opening is located or can be moved in a position closely adjacent to the filling opening.

The bottom of the storage container is at the level of the lower edge of the filling opening or slightly above and extends close to it to at least 2 cm or at least 1 cm or even into the filling opening.

As a result, the material to be pressed can be pushed into the filling opening along the bottom of the storage container.

(Lifting / tilting device :)

The filling device preferably has a tilting device for tipping a filled collection vehicle into the storage container, in particular a lifting / tilting device, by means of which the collecting trolley can first be raised to a corresponding height until it can be emptied by tilting it into the high-lying filling opening of the storage container.

Thus, the filled collecting container does not have to be emptied manually into the storage container, but this is done automatically and in a power-saving manner by means of the tilting device, in particular the lifting / tilting device.

This is preferably designed so that the collection trolley is only lifted up as little as possible to empty it, since it protrudes far upwards due to the tipping over the filling opening, and often only a limited height is available at the place of use of this baler

The tilting device preferably has a fastening device for fastening a collection vehicle which, in the lowered position of the tilting device, can be connected to the tilting device, for example, by simply contacting and locking it, and can then be automatically lifted up and emptied.

The collection trolley only has to be brought into contact with the fastening device manually, and if this does not result in automatic locking, it must be manually fixed to it. A sensor preferably again monitors whether a collecting container is present and / or correctly fastened on the fastening device and thus the tilting device.

(Supply slide :)

In order to transport the material to be pressed from the storage container into the filling opening of the box press, the storage container preferably has a driven one Supply slide open, which can be moved towards and away from the filling opening between two end positions so that this also does not have to be carried out manually.

In one end position, the supply slide closes the filling opening of the press box and its front surface is then part of the inner surface of the press box and / or the supply slide is part of that side wall in which the filling opening is located. This keeps the number of components and the weight of the baler low.
In the other end position, the storage slide is located at the end of the storage container facing away from the filling opening, in order to be able to fill in loose pressed material in between.

The storage slide can either be moved back and forth in the storage container or the end wall of the storage container facing away from the filling opening is itself the storage slide and can move in the transverse direction to the filling opening. This keeps the number of components low.

The side walls are then preferably designed to be variable in length, in particular designed in several parts, in particular designed to be telescopic, but they can also be rigid, one-piece side walls which then continue to strive far away from the rear of the actual baler when the front wall moves in the direction of the filling opening.

The supply slide is usually moved by means of slide cylinders on both sides, preferably extending in its direction of movement, or another slide drive.

A particularly space-saving arrangement results when these slide cylinders run along the outer sides of the storage container and in particular also along the outer sides of the transverse walls of the press box, since they then usually do not protrude further than the storage container itself in any of their possible positions.

They are preferably designed as pull cylinders, that is to say designed so that pressure can be applied to the cylinder in particular in the direction in which the piston is retracted.

(Lid flap :)

So that when the loose material to be pressed in the storage container is pushed forwards in the direction of the filling opening, the loose material to be pressed does not pile up over the upper filling opening of the storage container, the storage container has a cover flap which is between a closed position that closes the filling opening or, in particular, the entire open top of the storage container an open position that does not close, in particular leaves it completely open, can be displaced, in particular pivoted, so that in this open position the filling opening is available for filling in loose material to be pressed.

In the closed position, the underside of the cover flap should run parallel to the bottom of the storage container in order to create a channel that remains constant in height and which the storage slide essentially fills in height in each of its functional positions.

At its free end, i.e. facing away from its pivot axis, the lid flap can also have a crank or other holding elements which are directed towards the interior of the storage container in order to prevent pressing material from being pushed out over the rear edge of the storage container when the lid flap is lowered.

The storage slide should of course fill the channel created by the closed storage container in the direction of the filling opening as far as possible, also in terms of width in all of its functional positions.

(Guide flap :)

As an alternative to this, the storage container can comprise a guide flap which, with its underside, serves as a guide surface for the loose material to be pressed towards the filling opening.

For this purpose, it can be displaced, in particular pivoted, between a guide position that is inclined to the floor above the filling opening of the storage container, in which the underside of the guide flap approaches the floor of the storage container in the direction of the filling opening, and an open position that does not overlap.

As a result, the upper edge of the supply slide does not rest on the underside of the flap or comes close to it, but no significant force has to be applied to press the flap down, as is the case with a lid flap. Instead, the supply slide pushes the loose material to be pressed along the bottom in the direction of the filling opening, whereby the material to be pressed can tower up over the upper edge of the supply slide, limited only by the underside of the guide flap.

By moving the supply slide back and moving it forwards again, a considerable amount of loose material to be pressed can still be introduced into the press box in several strokes.

It is advisable to provide a cover element extending from the upper edge of the supply slide in the direction away from the filling opening in order to prevent pressed material from falling behind the supply slide, i.e. on the side facing away from the filling opening.

At least in the guide position, side plates are then preferably present which, in the guide position, close the free space between the side edges of the guide flap and the edge of the filling opening of the storage container, in order to prevent pressed material from escaping or protruding from the side.

(Inclined travel :)

In order to keep the overall height of the filling device as low as possible and to position its filling opening as low as possible for this purpose, the bottom of the storage container can rise obliquely upwards, at least from the end of the bottom area that is located below the filling opening, preferably over its entire length be trained.

Nevertheless, the floor is designed as a flat surface and rises towards the filling opening, in particular towards its lower edge, so that the supply slide can be moved in a linear sliding movement along the floor and can always keep the same, small distance to the floor or even the floor can touch. For this purpose, the feed direction of the storage slide runs parallel to the bottom of the storage container.

Nevertheless, the front side of the supply slide is preferably arranged parallel to the inner surface of that side wall in which the filling opening is located so that the supply slide is part of the corresponding side wall of the press box in its end position in which it is located in the filling opening and its inner surface is with it the inner surface of the corresponding side wall can be aligned.

(Storage container can be lifted :)

Alternatively, the storage container can be attached to the press box so that it can be moved vertically and up to an upper position in which the press box-side edge of the floor is flush with the lower edge of the filling opening in a side wall, in particular the rear wall, of the press box or is slightly higher, be liftable.

When the collection truck is tipped in, the storage container is then in a lowered, low position just above the ground, so that the almost Upside down collection trolley does not protrude very high when it is emptied into the storage container.

(Separate drives :)

Frequently, not only the at least one ram, but also the moving parts of the automatic filling device, i.e. in particular the storage slide and / or the cover flap and / or the tilting device or lifting / tilting device and / or possibly the liftable base and / or the liftable base as a whole are often used Reservoir, operated by means of working cylinders, in particular hydraulic cylinders.

The working cylinders of the automatic filling device, in particular its slide cylinders, can be operated with the same working medium as the press cylinder or cylinders that operate with at least one press ram, and can also be supplied with pressurized medium from the same pressurized medium source.

Preferably, however, the filling device and the ram should be able to be actuated independently of one another, in particular partially overlapping in time, and for this purpose there are preferably two separate and / or separately controllable drives for the at least one ram on the one hand and at least one or some movable parts of the filling device on the other hand, in particular two independently controllable hydraulic pumps

(Strapping device :)

A strapping device is preferably also provided in the box baler according to the invention in order to tightly strap the finished bale with a flexible strapping material, for example a strapping tape or a binding wire, before removal from the baler and thus to avoid a re-enlargement or even a falling apart of the pressed bale.

In the context of the present invention, only a binding wire is spoken of, without restricting the strapping material to this.

Such a strapping device preferably comprises at least one wire pusher that is able to pull the binding wire, in particular its end, which can be designed as a wire eyelet, between the press ram and the top of the bale from the back to the front of the press box.

With regard to the operating method for operating a vertically acting box baler, in particular a vertically acting box baler as previously described, this object is achieved in that the known automatic filling of the baler or its press box is carried out in batches.

This means that very little personnel work can be done in batches of loose material to be pressed, in that the loose material to be pressed is automatically pushed through the filling opening into the press box, in particular pushed into it, until the entire batch of pressed material is inside the press box.

(by means of a cover flap or guide flap :)

In this case, the loose material to be pressed is preferably compressed in height before or during the pressing into the press box to a height which is equal to or less than the height of the filling opening of the press box.

As a result, the pre-compressed material compressed in this way can be moved into the press box through the filling opening, for example pushed into it, without further measures.

(Keep width :)

For the same reason, it is preferably also necessary that the loose material to be pressed is arranged on the bottom of the storage container either over an equal or smaller width than the width of the filling opening or before or during the pressing into the press box before it is pressed into the press box The width is compressed to a width that is less than the width of the filling opening.

(Filling while pressing :)

In order to increase the throughput of the baling press, the next filling is preferably already being prepared while the material to be pressed is being pressed in the press box. For this purpose, at least the emptied collection trolley is preferably moved back by the tilting device into the docking position in which it stands on the ground and can be detached from the tilting device, in particular a new, filled collection trolley is already attached to the tilting device.

During the pressing of the bale, the storage container of the filling device can possibly be filled again, because the storage slide can be moved back from its front end position, in which it is part of a side wall of the press box, as soon as the ram has passed the filling opening and further forward moves down, and even more so while it then moves back to its upper starting position.

If necessary, the storage container can even be filled again when the storage slide is removed from the filling opening of the press box has not yet reached the most distant starting position, but then the space on the side facing away from the front surface of the supply slide, which is part of the side wall of the press box during pressing, must be covered at the top in order for pressed material to fall into this area avoid.

(Inclined travel :)

In order to be able to fill the storage container at the lowest possible height, the loose material to be pressed is pushed up to the level of the filling opening before being pushed into the press box.

(Raise the storage container :)

Alternatively, before being pressed into the press box, the material to be pressed can be lifted up to the level of the filling opening, in particular together with the storage container in which it is located.

(Strapping :)

In order to be able to strapping the bale even with the baler construction according to the invention - although the binding wire must not run in front of the filling opening of the press box during the production of the bale - the binding wire, in particular its end, can be in the form of a wire according to the invention -Eye, arranged at a height in the press box which corresponds approximately to the height of the upper end of the finished bale.

Then, after completion of the bale and the press ram still resting on it, the wire, in particular the wire eyelet, can be pushed or pulled through the press box from the back to the front, for example between the press ram and the upper end of the bale, so that it is at the front end of the Press box - with the removal door open - is accessible and is available for connecting to the other end of the binding wire, which is guided around the pressed bale and placed in the press box before the production of the bale begins.

a second design of a baling press according to the invention in side view, top view and front view.

The Figures 1a -c and 2a-c show a first design of the box baling press 1 according to the invention and a collecting trolley SW, in which pressed material P such as empty cardboard boxes are collected for loading this baling press 1, but in Figure 1 on the one hand and Figure 2 on the other hand in two different operating states.

The box baler 1 in the figures points with its front side 1a to the right and with its rear side 1b to the left.

A generic vertically acting box baler comprises - and these elements are also present in the baling press according to the invention - a press box 2 with a bottom 2a, which in this case has an approximately rectangular shape when viewed from above, so that a total of four side walls from its outer areas 2.1 to 2.4 protrude upwards, namely a front wall 2.1, a rear wall 2.2 opposite this, as well as longitudinal walls 2.3, 2.4 connecting these two walls, so that the inner surfaces of the side walls that adjoin each other result in a circumferentially closed rectangle when viewed from above.

In the press box 2 is - as best in the Figures 1b and 2 B can be seen - a ram 3 in the form of a plate lying horizontally and thus parallel to the bottom 2a of the press box 2 in the vertical, the pressing direction 10, movable up and down, which can press the pressed material P lying in the press box against the bottom 2 .

The ram 3 is attached to the lower ends of the piston rods 14.1-14.3 by several press cylinders 13.1 to 13.3 which are vertically spaced apart in the second horizontal transverse direction 11.2 and project beyond the upper end of the press box 2 and which are designed as hydraulic cylinders.

To apply high press forces, the two outer press cylinders 13.1 and 13.2 are extended downwards, while the middle press cylinder 13.3 with its smaller cross-section is used as a rapid traverse cylinder, for example to quickly move the press ram 3 back up into the deactivated position.

Between the vertically running press cylinders 13.1 to 13.3 , which are arranged in a common plane and parallel to one another, there is a respective guide rod 15a, b, the lower ends of which are also firmly connected to the press ram 3 and an inclined position and thus tilting of the press ram 3 in the press box 2 should prevent.

The front wall 2.1 present on the front side 1a is articulated to one of the longitudinal walls 2.3 via a vertical pivot axis and can be pivoted open like a door with respect to this - as in FIG Figure 2a shown - for removing a finished bale.

For pressing, the ram 3 moves down to the level of the lower end of the filling flap 2.1.1 and thus the front filling opening, so that a finished bale has a height that also only extends approximately to the lower end of this filling flap 2.1.1.

As best in Figure 1b As can be seen, the ram 3 can be withdrawn upwards to at least the upper end of the front filling opening, i.e. the upper edge of the filling flap 2.1.1, because press material P must be thrown into the space below the ram 3 .

In a generic vertical box baling press, the rear wall 2.2 of the press box 2 is closed or has at most - if the finished bale is to be strapped - slots for the strapping medium to pass through. The rear wall 2.2 is preferably made as a one-piece welded part, and the press box 2 is filled with press material P from the front side 1a , in that the upper part is designed as a filling flap 2.1.1 in the movable front wall 2.1, which thereby forms a removal door 12 , which is movably attached to the rest of the front door 2.1 and can be moved downwards along guides so that a filling opening is open in the upper part of the front wall 2.1 through which press material can be thrown in from the front side 1a.

The illustrated invention is also vertically acting, box-baler 1 has on the one hand in the upper region of the rear wall 2.2 2.2a a filling opening, the invention can be automatically filled by them in accordance with.

The filling opening to be opened in the front wall 2.1, formed as described by the formation of a filling flap 2.1.1 in the removal door 2.1, may also be present, but this is not a prerequisite for the implementation of the invention. The front front wall 2.1 can be designed as a closed removal door 12 that can only be moved as a whole as a door.

The automatic filling takes place by means of a filling device 20, which comprises a box-shaped storage container 21 , which connects on the outside to the rear wall 2.2 of the press box 2 and one into the Figures 1 and 2 has a horizontally extending bottom 21a , from which side walls 21c , d and at the free end an end wall 21e protrude, the side walls extending as far as the filling opening 2.2a in the rear of the press box 2.

The upper side 21b of the storage container 21 can be closed by a lid flap 25 , which extends around a horizontally extending pivot axis 25 ' near the press box 2 between the folded-down position of the lid flap 25, which closes the upper side 21b , in which the lower side is parallel to the bottom 21a of the storage container 21 runs into a filling position that is pivoted upward in comparison - as in the Figures 2 shown - it can be pivoted with the aid of a pivot cylinder 28.

In this filling position, a collecting trolley SW filled with pressed material P , which is open at the top, can be swiveled up and emptied over the upper edge of the end wall 21e of the storage container 21 into the latter.

The lifting, tilting, emptying, tilting back and setting down of the collecting trolley SW is usually carried out automatically by means of a lifting / tilting device 22 as they are in the Figures 3a - c is shown and described.

After the collection truck SW has been pivoted back, the cover flap 25 can be closed again with the aid of the swivel cylinder 28 , the swivel cylinder 28 being able to provide sufficient swiveling force that loose pressed material P protruding beyond the height of the upper edge of the end wall 21e from the underside 25a of the cover flap 25 is squeezed below this level.

Inside the storage container 21 is a supply spool 24 between a retracted position close to the end wall 21e and a forward or preferred position near the filling opening 2.2a of the pressing box 2 movable, wherein the supply slider 24 travels along with its lower edge close to the bottom 21a.

In the advanced end position - see Figure 1b - The supply slide 24 is preferably not only close to the filling opening 2.2a, but in this filling opening 2.2a, which it completely closes so that it becomes part of the rear wall 2.2 of the press box 2 and its front surface facing the press box 2 with the inner surface of the rest Rear wall 2.2 is aligned.

The supply slide 24 is moved by means of two slide cylinders 26a, b, which run along the outer sides of the side walls 21c, d of the storage container 21 and also along the longitudinal walls 23, 24 of the press box 2 in the first horizontal transverse direction 11.1 , one end of each slide cylinder 26a , b is attached to one of the longitudinal walls 2.3, 2.4 in the vicinity of the front wall 2.1 , while the other end is connected to the storage slide 24 through the side wall 21c , d of the storage container 21 .

The slide cylinders 26a, b are preferably designed as double-acting hydraulic cylinders that can be acted upon in both directions.

The design of the Figures 1 and 2 the bottom 21a of the storage container 21 runs horizontally, i.e. at right angles to the rear wall 2.2, and the plate-shaped storage slide 24 is at right angles to the base 21a and thus vertical, and fills the cross section of the storage container 21, i.e. transversely to the direction of extension of the slide cylinders 26 a, b, the sliding direction 24 'of the supply slide 24, completely so that no pressed material P can get in between.

Because with such a training when filling, as in Figure 2a , b It can be seen that the raised and tilted collecting trolley SW protrudes beyond the baler 1 and thus requires a large available height at the place of use Figures 3a - c a second design of the baling press 1, in which this required height is less, in particular not greater than the height of the vertical box baling press 1 itself:
The main difference compared to the first design of the Figures 1 and 2 consists in the fact that the bottom 2.1a of the storage container 21 does not run horizontally, but rather rises at an angle to the rear filling opening 2.2a in the rear wall 2.2 of the press box 2 .

As a result, its free end facing away from the press box 2 , i.e. also the end wall 21e and its upper edge, is significantly lower than in the first design, so that the collecting trolley SW does not have to be lifted so far for emptying over this upper edge and thus in its - in Figure 3a also shown - emptying less far protruding upwardly, namely hardly over the height level of the upper end of the rest of the baler, in particular the upper ends of the press cylinders 13.1 - 13.3, addition.

How Figure 3a shows, the end wall 21e of the storage container 21 is still vertical, and just like that arranged therein as in the first design Supply spool 24, but the shift direction 24 'of the supply spool 24 is no longer horizontal but is inclined rising in parallel to the bottom 21a of the reservoir 21st

The rest of the training of the baler 1 corresponds to that of the first design of the Figures 1 and 2 , but in the Figures 3a - 3c In addition, the lifting / tilting device 22 is shown, which lifts the filled collecting truck SW , which has been driven up to the ground and fastened therein, and tilts it into the correct position and empties it into the storage container 21.

For this purpose the collection trolley SW is tipping device coupled by means of a fastening device 23 of the lifting / tipping device 22 with the lifting / 22, which in this case - as in Figure 3b can be seen - when viewed from above, it has a U-shaped fork into which the collecting trolley SW can be retracted in the 2nd transverse direction 11.2 and locked there automatically or manually. This U-shaped fork is then raised and tilted by a motor along corresponding guides of the lifting / tilting device 22 together with the collecting trolley SW.

Furthermore, in the Figures 3a - c the best in Figure 3a recognizable, optionally present, side plates 29a, b are present, which extend them upwards in alignment or parallel to the side walls 21c, d of the storage container 21 , whereby the filling volume of the storage container 21 is increased. The lid flap 25 pivots between the in Figure 3a open position shown - in which it mostly only slightly covers the open top of the storage container 21 - with their side edges tightly fitting between the side plates 29a, b down to the lower end position.

When used as a cover flap 25, this lower end position is an end position parallel to the base 21a , in which the distance between the closed cover flap 25 and the base 21a then remains the same over the entire displacement path of the supply slide 24 , in particular until it has reached its end position in the filling opening 2.2a and becomes part of the corresponding side wall 2.2 there.

If the side plates 29a, b are present, the cover flap 25 can, however, also be used as a guide flap 25 * , which means that the lower end position is not an end position parallel to the floor 21a , but a position that runs obliquely to the floor, in which the distance between the guide flap 25 * located in this end position and the bottom 21a of the storage container 21 decreases from the free end wall 21b in the direction of the filling opening 2.2a.

When moving in this operating mode of the supply spool 24 from its retracted end position in the direction of filling 2.2a, pressed material can reach 24, and therefore from the upper end of the supply spool 24 covering from a free space to the upper edge of the free end wall 21b cover over the upper edge of the supply spool 27, which can be changed in length or displaced, is present.

In order to push the entire pressed material into the press box 2 in this mode of operation, several working strokes of the supply slide 24 may be necessary, but for this the pivot cylinder 28 for the cover flap or guide flap must be made less strong and / or a higher filling volume can be used in relation to a smaller volume of the storage container 21 can be coped with during a filling process.
