Figures 1 to 5 show a baler 1 with a new ejection device 2. The baler 1 consists of a press housing 3, with a bottom surface 7, a rear wall 5, a front door 6 with an integrated filler flap, not shown, and side walls 4, and a shaft 34 surrounded by the press housing 3, with at least one pressing area 8 and a filling area 9 located above it, as well as a drive for the baling press, which is arranged above the latter 9 and is not shown here in FIGS Chute 34 movable press plate 15 is connected.
The new ejection device 2 consists of a lifting plate 10, which is rotatably mounted on the bottom surface 7 in the pressing area 8 of the shaft 34 by means of a bearing 11, a pull rod 12 with a sliding piece 12a, which is preferably guided longitudinally - vertically - in the rear wall 5 the lifting plate 10 is connected in an articulated manner by a hinge 14 and has a specially angled end 24 in the upper end region, which protrudes into the pressing region 8, and from a driving device arranged on the pressing plate, from which parts can temporarily be pivoted into the effective region of the end 24 of the pull rod 12 are.
For this purpose, according to FIG. 3, a driver is provided on the press plate 15, which consists of a switching pawl 16 and a driver hook 17 and is pivoted into a basic position such that the press plate 15 can move; the driver hook 17 is in particular L-shaped.

When the front door 6 is open, the driving hook 17 is pivoted into the eject position by the movement of a guided slide 18 via a handle element 19, the slide 18 actuating the pawl 16.
The switching pawl 16 and the driver hook 17 are fastened on a shaft 20 which is mounted in bearing blocks 21 and 22 which are fastened on the press plate 15.
When the front door 6 is open, the slide 18 can be moved through manually
Operation of the grip element 19 can be moved in the direction of the rear wall 5 of the baler 1. The switching pawl 16 and the driving hook 17 are pivoted into a working position by means of a switching element 23 fastened to the slide 18. If the pressing plate 15 now moves upwards, the pulling rod 12 is moved upwards via the catch hook 17, which engages in an angled end 24 of the pull rod 12, and the lifting plate 10 is pivoted upwards about the bearing 11 via the hinge 14. Due to the inclined position of the lifting plate 10 according to FIG. 2, the material bale shown in part is thrown out through the front door 6, which is opened here by approximately 180 degrees, from the pressing area 8 of the shaft 34 to the outside in front of the baling press.
During the upward movement of the pull rod 12, its upper region along with the slide 12a slides along the guide 13 arranged essentially in the rear wall 5 and is pulled outwards by this guide 13 so that its end 24 is pulled down from the catch hook 17 is and the tie rod 12 and the lifting plate 10 fall back into the starting position.
During the next downward movement of the pressing plate 15, usually the next pressing stroke, the catch hook 17 strikes with its lower edge against the end 24 of the pull rod 12 projecting into the pressing area and at the same time, together with its pawl 16, is automatically pivoted back into said starting position ,

The front door 6 is locked during the pressing process by a locking device on one of the side walls of the press housing 3, while it is connected to the other side wall 6 via hinges.
Figures 6 to 9 show a new locking device, a bolt 25 mounted on the press housing 3, which has a recess 26 into which a bolt 27 arranged on the front door 6 engages.
By pivoting the bolt 25 upwards about a bearing 28 by moving a handle 30, the bolt 27 snaps out of the recess 26 of the bolt 25 and the front door 6 can open according to FIG. 7 by a defined angular range by the bolt 27 moved along a guide edge 29a of a slot-like guide 29 starting below the recess until it strikes a nose 31 of the bolt 25 delimiting the guide 29.
Above this end region of the guide 29, the bolt 25 has an externally located hump 37 which, when the bolt 25 is raised further, strikes a securing pin 36 arranged above the latching bolt 27 in this phase of the opening process and an unintentional, rapid opening - the bolt 25 springs open the front door 6 still under pressure - prevented.
Only by lifting the latch 25 again after a short dwell time, in which the pressed bale, which is still in the press shaft, is relaxed and the front door 6 is substantially relieved of force, can the locking bolt 27, according to FIG Guide 29 slide and the front door 6 are fully opened.
Special extensions are the handle 30, which can be pivoted about a swivel joint 32 when the front door 6 is closed, so that the handle 30 can be set parallel to the front door 6 when not in use and does not protrude into the room, and the stop pins 38 arranged on the side wall which define the range of movement of the latch 25 limit and thus hold the bolt 25 in a position favorable for closing.

Further details of the new baler with respect to the third basic idea of the invention mentioned are shown in FIGS. 10 and 11, namely with regard to an improved (binder) belt guide.
The press plate 40 provided there is equipped on its rear side, that is to say the rear wall 5 of the press housing 3, with at least one projecting U-shaped web 41. At the end, the two legs of the U-shaped web 41 are closed by a bolt 42, so that an enclosed gap 43 is created, in which the binding agent for setting the finished pressed bale, usually tape, is guided.
The web 41 moves in a groove 5b provided in or on the rear wall 5, this groove 5b being formed by spaced-apart, angled legs 5a 'of profile parts 5a of the rear wall 5. The clear width of this groove 5b is carried out as described above. This groove 5b provided in the rear wall 5 of the shaft of the press, which is provided for receiving regions of the binding agent so that the binding agent is not stressed unnecessarily during the pressing process, is now kept free by the web 41 projecting into this groove, so that the binding agent is not unnecessarily influenced by waste material squeezed into the groove 5b during the pressing process.

The tape is fed in, in particular, via a tube 33, the lower partial region 33a of which is directed such that the tape is inevitably inserted into the gap 43 of the web 41 when inserted and pushed through the tube 33. The tube 33 can either be attached to the rear wall 5 of the press housing 3, or to the support structure of the drive unit (not shown) above the filling area 9 or to the press plate 40 itself.
The binding agent (not shown) is fed to the pipe 33 in a known manner, either from supply rolls arranged on the rear of the press housing or from supply rolls arranged in the front, upper region of the press.

The invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the disclosure.
Thus, only the new ejection device, only the new closure device or only the new belt guide can be used according to the invention on a baling press without thereby leaving the basic idea of the invention.
All new individual and combination features not disclosed further disclosed in the description and / or drawing are regarded as essential to the invention.
The equipment of the baler with one or more control units along with safety circuits or devices, binder storage, binder tensioning device and the like units does not relate to the subject matter of the invention here and were therefore not described further. This equipment of the baler is at the discretion of the operator or manufacturer of the baler.
