A basic idea of the invention is that the closure device for the front door is formed from a specially shaped bolt, which is arranged in particular pivotable on the side of the press housing and in whose recess a bolt of the front door can be latched.

In particular, it is provided that the closure device for the front door at least from the, in particular laterally, on the press housing pivotally mounted about a bearing, a slot-like guide and a handle having latch and the side of the front door in the corresponding area provided bolt is formed. The slot-like guide has at its end facing the bearing an upwardly directed recess and at its end facing the front door a substantially downwardly directed, passing into an exit recess.

In a further specific embodiment, the front door-side end of the slot-like guide is formed by a downwardly inclined nose, the lower edge ends below the imaginary extension of the lower leading edge of the guide and preferably above the lower body edge of the bolt and at the same time is the outer boundary wall of the exit.

Preferably, it is also provided that when unlocking the front door by lifting the bolt by means of a handle of the locking bolt along a leading edge of the guide of the bolt up to a trained as a nose, integrated into the latch limit stop is moved to the stop pin abuts, causing the on the front door acting expansion force of the pressed bale is intercepted. After a short dwell time, then the front door is fully opened in preparation for the ejection of the bale. For this is actuated by repeated operation of the handle of the pivotable about a bearing bolt and approximately simultaneous opening movement of the front door of the locking bolt under the raised nose away.

It is also advantageous that the handle of the bolt is mounted in a hinge and at least in the closed position of the front door to the latter is pivotally.

A preferred embodiment is that the arranged on one of the side walls of the press housing bearings of the bolt and provided on the relevant same side on the front door locking bolts, seen from the bottom of the baler from, lie approximately at the same height. It is also advantageous if the imaginary connecting line between the bearing and the locking pin is substantially a horizontal.
An advantage of the subject invention also that at the front door above the locking bolt and the latter spaced another bolt is provided. In this case, the lower of the two bolts is designed as a locking pin movable in the slot-like guide and the upper of the two bolts as a securing pin. This securing pin limits the movement of the bolt in the upward direction, corresponding to the upper contour line of the bolt.

Figures 1 to 5 show a baler 1 with an ejector 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 surrounded by the press housing 3 shaft 34, with at least one pressing area 8 and an overlying filling area 9, and a arranged above the latter 9, not shown here in Figures 1 to 2a, known per se drive for the baler, which is connected to a movable plate 34 in the press plate 15.
The ejector 2 consists of a lifting plate 10 which is rotatably mounted on the bottom surface 7 in the pressing region 8 of the shaft 34 by means of a bearing 11, a tie rod 12 with slider 12 a, which is preferably longitudinal - vertically - guided in the rear wall 5, with the Lifting plate 10 is hingedly connected by a hinge 14 and in the upper end region has a specially angled, projecting into the pressing portion 8 end 24, and arranged on the pressing plate entrainment of the temporary parts in the effective range of the end 24 of the tie rod 12 are pivoted ,
For this purpose, according to Figure 3 on the pressing plate 15, a driver is provided which consists of a pawl 16 and a driving hook 17 and is pivoted to a basic position so that a movement of the pressing plate 15 can take place; the catch hook 17 is formed in particular L-shaped.

The pivoting of the driving hook 17 in the ejection position takes place when the front door 6 is open by the movement of a guided Slider 18 via a handle member 19, while the slider 18 actuates the pawl sixteenth
The pawl 16 and the catch hook 17 are mounted on a shaft 20 which is mounted in bearing blocks 21 and 22 which are mounted on the press plate 15.
When the front door 6 is open, the slider 18 can be moved manually by actuating the grip element 19 in the direction of the rear wall 5 of the baler 1. By means of a slider 18 mounted on the switching element 23, the pawl 16 and the driving hook 17 are pivoted into a working position. If the pressure plate 15 now moves upward, the pull rod 12 is moved upwards via the driver 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. As a result of the inclined position of the lifting plate 10 according to FIG. 2, the material bale shown in part is ejected out of the pressing area 8 of the shaft 34 outwards in front of the baler by the front door 6, which is opened by approximately 180 degrees.
During the upwardly directed movement of the pull rod 12, its upper region together with the slider 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 by the catch hook 17 is and the pull rod 12 together with the lifting plate 10 fall back into the starting position.
At the next downward movement of the press plate 15, usually the Next press stroke, the catch hook 17 strikes with its lower edge to the projecting into the pressing area end 24 of the tie rod 12 and is simultaneously pivoted together with its pawl 16 in the said starting position automatically back.

The front door 6 is locked during the pressing operation by a closure device on one of the side walls of the press housing 3 while it is connected via hinges 6 with the other side wall.
FIGS. 6 to 9 show a new closure device, a latch 25 mounted on the press housing 3, which has a recess 26 in which a bolt 27 arranged on the front door 6 engages.
By pivoting the bolt 25 upwards to a bearing 28 by means of movement of 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 Figure 7 by a defined angle range by the bolt 27th along a leading edge 29a of an opening beginning below the slot-like guide 29 moves until it abuts a guide 29 delimiting nose 31 of the bolt 25.
Above this end region of the guide 29, the latch 25 has an outer projection 37 which abuts on further lifting of the bolt 25 in this phase of the opening operation to a above the locking pin 27 arranged securing pin 36 and an unintentional, fast opening - popping of the bolt 25 by the still pressurized front door 6 - prevented.

Only by lifting the bolt 25 again after a short dwell time, in which the pressed, still in the press shaft bale relaxed and the front door 6 is substantially relieved by force, according to Figure 8, the locking pin 27 through the downwardly facing output 29b from the Slide guide 29 and the front door 6 are fully opened.
Special extensions are with the front door 6 closed pivotable about a pivot 32 handle 30, so that the handle 30 when not in use parallel to the front door 6 is adjustable and does not protrude into the room, and arranged on the side wall stop pin 38 which the range of movement of the bolt 25th limit and thus hold the latch 25 in a favorable position for closing.

Further details of the new baler relating to the above further basic concept of the invention are shown in FIGS. 10 and 11, relating to an improved (binder) tape guide.
The pressure plate 40 provided there is provided at 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 formed, in which the binder for setting the finished pressed bale, usually band, is performed.
The web 41 moves in a in or on the rear wall. 5 provided groove 5b, said groove 5b of spaced-apart, angled legs 5a 'of profile parts 5a of the rear wall 5 is formed. The inside width of this groove 5b is carried out as already described above. This provided in the rear wall 5 of the shaft of the press groove 5b, which is provided for receiving portions of the binding agent, so that the binder is not unnecessarily stressed during the pressing process, is now kept free by protruding into this groove web 41, so that the binder is not unnecessarily affected by waste material squeezed into the groove 5b during the pressing operation.

The feeding of the strip takes place in particular via a tube 33, the lower portion 33 a is directed so that the tape when inserted and pushed through the tube 33 is inevitably inserted into the gap 43 of the web 41. The tube 33 can be fastened either to the rear wall 5 of the press housing 3, or to the supporting structure of the drive unit, not shown above the filling area 9, or to the press plate 40 itself.
The supply of the binder, not shown, to the tube 33 is carried out in a known manner, either from arranged on the back of the press housing or arranged in the front, upper region of the press supply rollers.

The equipment of the baler with one or more control units together with safety circuits or devices, Binder storage, binder tensioning means and the like units here does not relate to the subject invention and were therefore not further described. This equipment of the baler is at the discretion of the operator or manufacturer of the baler.
