Definitions

  • 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.
  • 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.
  • 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.
  • the filling opening is usually on the front arranged opposite rear side.
  • the material to be pressed is therefore produced in batches at the baling press.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the pressing material produced in batches can be pressed very quickly by means of the baling press according to the invention.
  • 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.
  • 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.
  • 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.
  • 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.
  • the material to be pressed can be pushed into the filling opening along the bottom of the storage container.
  • 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.
  • 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.
  • 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.
  • the storage container 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the feed direction of the storage slide runs parallel to the bottom of the storage container.
  • 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.
  • 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.
  • the storage container 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.
  • 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.
  • 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
  • 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.
  • a flexible strapping material for example a strapping tape or a binding wire
  • 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.
  • this object is achieved in that the known automatic filling of the baler or its press box is carried out in batches.
  • 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.
  • 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.
  • 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.
  • the next filling is preferably already being prepared while the material to be pressed is being pressed in the press box.
  • 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.
  • 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.
  • 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.
  • the loose material to be pressed is pushed up to the level of the filling opening before being pushed 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.
  • 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.
  • the wire in particular the wire eyelet
  • 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.
