Guide arrangement for the ram of waste presses

The invention relates to the arrangement of the guide elements of the ram of presses for packaging office waste, carpets among other things used materials, in particular on presses of the type with vertical action ram drive, whereby

regardless of whether this drive is centrically pushing or on both sides is transmitted pulling on the tappet body, the latter at the known designs - sliding or on rollers - either supported only on the inside of the manhole or on the outer walls of the manhole and is led.

The common, major disadvantage of these known designs lies in the fact that occasionally inevitably occurring, extreme tilting forces, resulting from uneven or different Manhole filling with materials of different hardnesses, only insufficiently compensated and damage to the Lead press or its drive elements.

The present invention has therefore set itself the task of eliminating these disadvantages and introducing a new guide geometry to create in such a way that even extreme Hipp stresses on the plunger are better distributed on the guide surfaces and intercepted on them can be.

This problem is essentially achieved in that each of these At least one more guides on the adjacent side of the shaft opposite.

In a special embodiment of the invention it is provided that the respective adjacent guide elements at approximately the same height

and lie in a plane parallel to the tappet surface and also a pair of rollers lying horizontally apart from one another is provided for each guide point, and the mutual lilirk connection of all guides per shaft side preferably represents a triangle pointing with its tip in the pressing direction.

This inventive guide arrangement is opposite the known state of the art in this particular field For the first time proposed and achieved a geometry in which the arrangement of the supports, i.e. the position of the Guide points resulting, in the pressing direction elongated lever arms, between the individual guide points in perfect Form any kind of possible tappet tilting will.

An exemplary embodiment of the invention is shown in the drawing and then described in more detail.

They show in detail:

FIG. Z shows a cross-sectional profile as a detail along the line χ - y from FIG. 1.

The vertical type of waste press partially shown as a longitudinal section in FIG. 1 has, in addition to the area of the feed chute 1, that of the actual press chute 2, which is limited at the top by the ram end position shown. The plunger 3, 4 itself can be arranged in a centric pushing manner, indicated by dash-dotted lines 5a, or pulling over cylinder-piston units 5, 6 on both sides towards the shaft walls 7, these cylinder-calving units 5 , 6 are supported in any form on the press, or the walls or housing 7 via brackets 8. The force is transmitted from the piston 6 to the tappet socket k by means of the tabs 9 which, via a fork head 1D or the like, engage the tappet yoke 3 on the one hand on the piston rod G and on the other hand through slots 11 in the shaft walls 2a.

To now, for example, the edging stresses or edging forces from a one-sided load or impact C without damage to the drive and machine system are on both sides of each shaft wall 2a and preferably also on both sides of the landing slots 11, roller

pairs 12, 12 'arranged such that the rollers 12, 12' once have a certain distance ζ from one another and also at least one of the pairs on one side to the other pair of the same Side have as large a distance B as possible. This then creates the supporting lever arm, which in this case Guide geometry, possible bzui. unilateral loads compensates.

The roller arrangement in the form of a triangle according to FIG. 1a with its tip in the pressing direction is advantageous and sufficient at the same time. While in the illustrated embodiment the guide rollers 12 on the outer shaft side, which can be adjusted in a known manner, sit on a Honsolplatte 13 and with this on cen tabs 9, the pairs of rollers on the inside of the shaft are also via brackets 1Λ, 15 or directly, ωίε IZ ¹ , on the bztj . arranged in the Stößeljach. üJandungs reinforcement ribs 16 and the dash-dotted line covers 17 for the drive parts 5, 6 complete this press.
