The present invention relates to a method for compressing articles and materials, in particular used packaging or transport and / or storage containers, for example cardboard, sheets, plastic bottles, etc., based on the preamble of claim 1. Squeezing).

[0002]

2. Description of the Prior Art Many waste presses of various types are known from the prior art for compressing used packaging materials and other articles mentioned above, as well as pressing such waste presses. Many methods and devices are known for manually or automatically tying the bale material.

[0003] For example, German Patent Application Publication 197
From 38060 A1 there is known a waste press (so-called vertical bundling press) with a discharge device for the bale that has been pressed, in which case the rocking area of the press shaft of the waste press is swung. A possible lifting plate and a pull rod guided substantially by the rear wall and pivotally connected to the lifting plate are provided. The pull rod can be selectively removably connected to a vertically movable press plate of the waste press by a connecting member for discharging the finished bale material, wherein the connecting member is connected to the press machine. Depending on the position of the front door closing the shaft, it is mechanically forcibly connected and turned on and off.

[0004] To close the press shaft, a front door rotatably supported on the side wall of the shaft of the press is brought into contact with the edge (end face) of the opposing side wall and locked to the edge by a safety lock. Such safety locks are known in various forms, such as the "handle wheel adjusting spindle" type lock described in German Utility Model Specification 29721834 U1, and in German Offenlegungsschrift 1954.
A laterally swingable "lever" type lock as described in 5766A1 is known.

[0005]

The object of the present invention, on the basis of the above prior art, is on the one hand the opening of the front door (bundling press door) or the press shaft door, and / or the binding and discharging of the material veil. And to improve the overall structure of the bundling press so that the safety of the opening and closing of the door of the bundling press is improved. It is desirable to keep the technical costs for producing the clamping press low.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to provide a bale press based on the preamble of claim 1 or 7,
This is achieved by means and measures according to the features of claim 1 or in a juxtaposition with claim 7. The subordinate dependent claims 2 to 6 and 8 to 12 contain advantageous developments and variants of the subject matter of the invention.

The present invention relates to a packaging press for compressing (squeezing) articles and materials, in particular used packaging materials or transport and / or storage containers, for example cardboard, sheets, plastic bottles and the like. Vertical bale press, wherein the closed front door of the press casing is locked by a "lever" type lock and / or has a bale discharge device in the lower area of the press machine shaft, the so-called press shaft. Is assumed. The discharge device usually has a lifting plate pivotally supported on the surface of or inside the bottom surface of the shaft constituted by the press casing, and is guided by the rear wall of the press casing and is also pivotally connected to the lifting plate. The pulling rod is then selectively connectable by means of an entraining device to a press plate movable in said shaft, so that, if necessary, usually at least the press area of the shaft is closed. When the front door is open, the discharging device can be operated by the press plate moved upward.

[0008] In a novel and advantageous manner, the entraining device is designed as an entrainer which is oscillating and can be temporarily connected to a pull rod, wherein the entrainer is provided with a pawl and an entrainer hook. An inward basic position, consisting of an axle supported on the bearing pedestal, at least when the front door is closed, at least the entrainer hook, and preferably also the pawl, pointing away from the rear wall. And at least temporarily when the front door is open for the bale discharge phase, occupies an outwardly directed discharge position pointing toward the rear wall.

In this discharge position, the connection between the follower hook and the pull rod of the discharge device is established at least temporarily during the upward movement of the press plate.

[0010] Advantageously, the bearing block of the entrainer further comprises a shaft,
The pawl and the driver hook are positioned on the press plate, and the driver can be actuated by the pawl.

[0011] Advantageously, it is provided that the driver hook is provided as a hook, which is in particular configured in an L-shape.

Furthermore, it is advantageous if the pawl is movable by means of a slider guided on the press plate, which is actuated manually or automatically by the gripping member when the front door is open.

[0013] The same basic idea as described above in the novel packing press is based on the fact that the closing device for the front door is constituted by a specially shaped latch which is pivotally arranged, in particular on the side of the press casing. That is, the bolt of the front door can be locked in the notch of the latch.

In a special embodiment, the closing device for the front door is arranged so as to be pivotable about a bearing at least, in particular on the side of the press casing, and has a slot-shaped guide and a grip. And a bolt provided in a corresponding area on the side of the front door. The elongated guide has a notch facing upward at the end facing the bearing and an outlet facing substantially downward at the end facing the front door. The notch has transitioned to.

In a further special configuration, the front door-side end of the elongated hole-shaped guide portion is formed by a downwardly inclined lug, and the lower edge of the lug is formed by the guide portion. Ends below an imaginary extension of the lower guide edge and above the lower body edge of the latch, and at the same time forms a partition outside the outlet.

Further advantageously, when the front door is unlocked by raising the latch with a grip, the locking bolt is configured as a lug along the guide edge of the latch and is integrated with the latch. It is intended that the stop bolt be movable up to a stop stop against which a locking bolt abuts, whereby the expansion force of the pressed bale acting on the front door is received. After a short waiting period, the front door is fully opened to prepare for bale discharge. Re-operating the grip of the pivotable latch about the bearing causes the bolt to be unlocked below the raised lug to bring the front door to the open position.

Advantageously, the grip of the latch is supported by a rotary joint, and when the front door is in the closed position, the grip can swing toward the front door.

One advantageous embodiment consists in that the bearing of the latch, which is arranged on one of the side walls of the press casing, and the locking bolt, which is provided on the same side of the front door, are viewed from the bottom of the baling press. When they are located at almost the same height.

Further, it is advantageous if the imaginary connecting line between the bearing and the locking bolt is substantially horizontal.

In the object of the present invention, it is also advantageous that the front door is further provided with another bolt above the locking bolt and at a distance from the locking bolt. In this case, the lower one of the two bolts is configured as a movable locking bolt in the elongated hole guide, and the upper one of the two bolts is configured as a locking pin. The stop pin limits the upward movement of the latch, corresponding to the upper contour of the latch.
