Description

The invention relates to a baler, particularly a vertical one Type, with guide units for setting agents, in the Waste materials such as used containers and others Paper, cardboard, plastic and similar materials or also metal cans, which are used for storage purposes, the packaging and transport were used, and in particular used office items from the aforementioned Materials compacted to reduce volume - pressed together. In particular, the Invention on means provided on or in a baler, which is an improved reception and / or management of Enable binding agents and also save money on the Manufacturing costs and consumption costs have an impact.

A baler is known according to US 4,041,856, the one Press box has a substantially vertical Shaft that has a press area above its bottom and has a filling area above it, in which one Press plate is movable, the shaft of one Rear wall and two opposite Side walls, as well as at least the pressing area final front door is formed, and at the on the Inside of the floor and partly on the inside of the rear wall Means for guiding binding agents are provided.

With this baler, after baling, before the last press stroke, in the door of the baler existing slots each have a binding agent in the guide channels inserted and pushed until the same at the back of the bale the top surface of the bale appears. Then this becomes Setting agent pulled forward and after the execution of the last press stroke, with those in the lower press position Press plate, the strapping of the finished pressed bale performed. The disadvantage here is in particular that the in Guide channels inserted ends of the binding agent step out of the guide channel during insertion can and get caught in the bale; multiple, time-consuming insertion and partial retraction necessary here.

A baler is also known from US 4,182,236, with the last on the inside of the floor Front to back are provided, each one Have groove-like groove for receiving setting agents. In the The rear wall of the press are aligned with the leading grooves Slots are provided so that the setting agent during the Moving around the bale at least in the area of Back wall not directly along the bale surface must be pushed, what the danger of snagging the End of the binding agent in the bale. The disadvantage here however, that while guiding the setting agent around the Bales around, the operator temporarily behind the baler must occur, creating additional footprint (space) for a press workplace must be kept available.

A baler according to US 4,232,599 is similar to that The aforementioned, however, the groove-like grooves for guidance in Bottom area in the surface of the bottom of the press shaft incorporated, reducing the manufacturing cost of a Baler can be adversely affected.

It is also known and common in vertical balers that Setting agents, such as string, fiber tape or strapping wire, in the intended number, before the start of each Press cycle, at least in sections, in the shaft of the Press box are inserted. To position this Setting agents are said on or in the floor and / or additional on or in the rear wall of the press shaft Press box provided means used.

The setting agent is replaced by those during the pressing process, especially in the area of the floor, the press shaft protected from excessive mechanical stress. A such arrangement is in the baler after the DE 44 46 748 C2 shown. This baler is on the outside the back wall of which holds supply rolls with binding agent, whereby the baler at the installation site further on the wall can be prepared, which means the required footprint could be kept smaller than previously known.

According to DE 298 12 539 U1 is another baler known, in which the setting agent on supply rolls above of the press shaft is stored towards the front. From here the binding agent is moved down to the front area of the Press plate guided, deflected there, along the press plate the rear area led, there again turned and in Channels of the rear wall of the press to the floor area and thence in channels along the floor to the lower front the press plate where it is attached before the start of the press becomes. So that the inserted binding agent during the Pressing process is not tightened, is below the Storage rolls, before entering the press shaft area a band brake arranged. During the movement of the The setting agent experiences a constant pressure on the press plate Tensile load. At least during the first one Pressing cycle, i.e. when on the floor area of the Press chute is not yet much pressed waste material, the weight of the bale that has not yet been completed is very low is the deflection area of the binding agent in the Transition zone from the back wall to the bottom of the Press shaft due to the upward movement of the Press plate existing tension in the direction of Pressed area. This creates the risk that Setting agent from the bottom guide means slides out and at the next press movement of the Press stamping the binding agent unnecessarily mechanically is claimed or at one point on the bottom Surface of the bale is pressed in during the Pressing no band channel was formed. Especially with the This disadvantageous phenomenon is still present after the first press strokes permanently available.

The object of the invention is therefore for a Bale press of a vertical design and new constructional means Finding arrangement with which to insert the binding agent in preparation for the setting of finished pressed bales can be simplified while ensuring a more secure positioning of the binding agent in the area the bottom of the press shaft, taking into account at the same time the cost optimization for the manufacturing costs of a Baler, as well as consumption costs during the Use of the baler.

The object is achieved by a baler with the features of claim 1, in particular by its characteristic features solved. The subordinate Claims 2 to 13 disclose further developments and Variants of the invention. Other special details to further developments or design variants of the invention can be seen from the description and the drawings.

The invention is basically based on a baler from, which has a press box, with a substantially vertical shaft, one above its bottom Press area and a filling area above it, in which a press plate is movable, the shaft of one rear wall and two opposite one another Sidewalls and at least the press area closing front door is formed, and at least on or at least one guide unit in the bottom of the shaft is provided for receiving / guiding binding agents whose one end to the back wall and the other end to Front of the bottom shows and one the ends passes through groove-like groove in which the bottom section of the binding agent is guided.

The new baler is particularly characterized by that with a few structural means a more secure positioning the setting agent in the area of the bottom of the shaft is guaranteed. This happens in particular through the special structural arrangement of the guide unit (s) in the Area of the bottom of the shaft. At least the groove-like one Groove of the guide unit is selective and / or in sections laterally offset to an imaginary, through which Arranged ends of the guide unit predetermined straight line. Through this punctual and / or sectionally lateral Offset to one through the endpoints of the leadership units straight line, every binding agent experiences at least a bending stress acting transversely in the horizontal plane within its elastic limits. This will make one non-positive, but at any time by a defined Tensile stress easily releasable positioning of the Setting agent achieved in the guide unit.

After further training it is provided that the Management unit itself, including the one provided in it groove-like groove, selectively and / or in sections to the side said predetermined straight line is arranged offset, wherein the laterally offset points or sections of the Guide unit alternating with the imaginary straight line are arranged.

Each guide unit provided can be made in one piece or be formed in several parts. According to the latter type, the Guide unit preferably at least two strips, the spaced strips including inclusion of the floor between them the groove-like Form groove.

To lock the after inserting the binding agent in the Guide unit protruding from the pressing area on the door side End of the setting agent, is at the front of the floor, each assigned to a guide unit and to the side of it arranged, such a wire holder having a labyrinth provided that the end of the binding agent to be locked during the locking process and its temporary locking its Do not exceed the elastic limit.

Furthermore, it is provided that the groove-like groove has a U-shaped, dovetailed, or bi-concave has the same cross-section.

The present invention can be used both when using cut (finite) setting agent as well as when deducting Setting agent from that held on the baler Supply roll can be used.

The invention is preferably used on balers which is the middle section of the setting agent cut to length through a slot in the rear wall guided on the outside, essentially describing an arch, in a compensation room provided behind the rear wall lingers.

The guide units arranged in the area of the floor are so designed that insertion is easy handle and inserted sections of the binding agent in the respective section of the management unit and that Setting agent during pressing much safer than so far lies in the bottom-side guide units.

Rigid setting agent is used as the setting agent appropriate material used, preferred Strapping wire, preferably with one of the ends in shape an eyelet is formed; the use of plastic tape, with and without reinforcing fibers or threads, e.g. B. metal threads, or PET tape, is also within the scope of the invention. there is understood to be rigid, that the material used, also in relation to the cross section used, in itself in is stiff, but at the same time still flexible (bendable).

With this fundamentally new concept, the posed Task completed. In addition, the so-called Footprint of the baler kept small; Strength Deflections and small bending radii are used in the setting agent avoided. This is compared to known solutions new arrangement for setting agents also minimizes costs.

Other advantages in terms of manufacturing costs for a Baling press of said type as well as for the operating costs this baler and the so-called required Footprint are created using the following extensions achieved to the invention.

According to another development, they extend to the inside pointing ends of the strips of the bottom Guide units each into the slots in the rear wall into it. Said ends of the strips are preferred bent up or angled; alternatively, you can special angular parts are provided for this corner area. This version offers additional protection for the Setting agent in the transition area from the floor to the rear wall and possibly prevents under extreme conditions pressure loads occurring in this corner area.

Cutting agents cut to length, such as e.g. B. are so-called eyelet wire after another extension in a preferably in the area provided on the rear wall. This The stockpile is essentially made up of a cross arranged quiver and a sideways near the ground one of the side walls of the press box arranged bracket educated. So one end of each setting agent is stuck transversely in the quiver while the other end by means of the said bracket deflected upward at approximately 90 ° is.

The invention is schematized in the following on the basis of FIG Drawings shown embodiments closer explained. Show

In Fig. 1 is a side view and partial section - section II - a baler 1 is shown schematically, in which the setting means 16 is partially guided outside the shaft 2 a. The baler 1 is placed on a footprint 10 . Your press box 2 comprises, as can also be seen from FIGS. 2 and 3, a base 9 and side walls 6 and 7 erected and projecting thereon, and a rear wall 5 , the side walls and the rear wall preferably being made of profile material.

On the front, see FIG. 1, the front door 8 is pivotally supported on the side wall 7 ; for reasons of better clarity, the same is not shown in the other figures.

The inside 6 a, 5 a, 7 a and 8 a, the door 8 is open here, describe the shaft 2 a, in which the waste material is filled and compacted. The shaft 2 a has a lower pressing area 4 and an upper filling area 3 . A press plate 36 is guided in the shaft 2 a, which is shown here in an upper position, the “fill” position, before the start of a press cycle. The press plate 36 is driven by a drive unit 31 ; the control signals come from a control unit 30 ; this unit 30 can also comprise a hydraulic part, see FIG. 2.

In the preferred embodiment according to FIG. 1, a setting means 16 cut to length is preferably used.

On the inside 9 a of the bottom 9 of the shaft 2 a, see FIGS. 1 and 3, guide units 26 , here the special designs 26 .1 to 26 .4, are provided for the protected reception of sections of the binding means 16 . Each of the multi-part guide units 26 .1 to 26 .4 preferably consists of two strips 27 , 28 spaced next to one another and essentially parallel to one another, between which the setting means 16 is guided. According to the innovation, the strips 27 and 28 of the guide units 26 .1 to 26 .4 are "A1" to "On" in sections offset laterally to a straight line "G" as intended by the end points 26 a and 26 b of the guide units 26 , preferably alternately, arranged, in each case adjacent sections "A1" and "A2" or "A3" and "To" connected to each other and these connection points contact and deflection points "U1". , ., "Un" for the setting agent. Between the two end points 26 a and 26 b of each guide unit 26 .1. , ., 26 n, which are themselves deflection points, is at least one further deflection point "U1". , ., "Un" provided.

The guide units 26 .1 to 26 .4 are also arranged on the floor 9 in such a way that they are aligned with slots 5 c provided in the rear wall 5 , which are essentially aligned vertically. As can also be seen in FIG. 3, the strips 27 , 28 of the guide unit 26 preferably extend into the slots 5 c provided in the rear wall 5 .

The sections of the rear wall 5 , each forming a slot 5 c, facing one another, are legs 5 d and 5 d 'from the inside 5 a to the outside 5 b, the slot width preferably narrowing towards the outward ends of the legs.

The central areas of the set binding agent are guided in the compensation space 14 provided behind the rear wall, which is defined by a covering 15 . alternatively, individual fenders arranged laterally from the slots 5 c can also be provided, which can also be baffles when arranged obliquely to the rear wall 5 .

In the case of the guide unit 26 .3, it is also shown by way of example with the reference symbol 29 - adjustment directions - that the strips 27 , 28 which form the groove-like groove 26 c of the guide unit together with the inside 9 a of the base 9 are also adjustable in their spacing from one another if necessary can be so that they can be adjusted to different sizes of binding agents.

For the sake of completeness, it is also shown in FIG. 3 that here a quiver 12 arranged at the level of the bottom 9 is provided on the back of the baling press 1 and a bracket 13 fastened to the side wall 6 or to the rear wall 5 is provided in the middle region, which together form a reserve for cut-off means 16 cut to length. The storage of binding agents 16 in such a store is also shown in FIGS . 1 and 2. There are shown, by way of example, binding means 16 which are inserted into the quiver 12 at one end and are held in an approximately vertical position at the other end with the aid of the bracket 13 . The bracket 13 is arranged in such a way that the stored binding means 16 , viewed from the side, do not protrude beyond the basic dimensions of the baler 1 , see FIG. 2.

In the following, the process of inserting binding agent into the shaft 2 a of the baling press 1 is roughly explained for the exemplary embodiment shown in FIGS . 1 to 3. By actuating the control unit 30 of the baler 1 , the press plate 36 moves into a predetermined position. The operator removes the binding agent 16 from a stocker 12 , 13 provided in the outer region of the baling press, slightly compresses the end regions of the binding agent 16 , the end region preferably having an eyelet 16 c being at the top, and pushes the resulting wire arch, the middle region of the binding agent, through a vertical slot 5 c in the rear wall 5 - Fig. 1 -.

As shown in this FIG. 1, the eyelet 16 c is completely pushed onto a fixing pin arranged on the press plate 36 .

The sections following the eyelet 16 c, the end region and the region close to the end, of the binding agent 16 are introduced through a gap present in the lower side of the press plate 36 and inserted in a guide channel running over the latter and guided into the rear region of the press plate 36 and there, pressed into a provided guide part, a spring clip that preferably opens downward.

The portion near the other wire end 16 d and the end region of the binding means 16 run along and on the inside 9 a of the bottom 9 in the guide unit 26 .1. The lower end 16 d of the end region is inserted and temporarily fixed to form a laterally guided curve or kink in a labyrinth 21 .1 of a wire holder 20 .1 arranged on the front 9 c of the base 9 , see FIG. 3a. The view of the viewer goes here from the direction of the left side wall 6 along the front 9 c of the base 9 in the direction of the right side wall 7 .

This new type of attachment of the end of the binding agent to the front, lower front 9 c of the press box 2 has the effect that during the pressing process, in which the operator of the baler approaches the baler several times to fill the filling area 3 , no disturbing loops or free ends are present in the front foot area of the baler, as is often the case with conventional balers.

The detail shown in FIG. 3a is shown in a top view in FIG. 3b. The guide unit 26. 1 , consisting of a strip 27 and 28, is arranged on the inside 9 a of the bottom 9 shown here in detail. In this exemplary embodiment, the wire holder 20 .1 is provided on the left side of the guide unit 26 .1, so that the binding means 16 inserted into the guide unit 26 .1 is guided in a curve against the front inner edge when threading and holding in the wire holder 20 .1 the bar 27 is pressed and thus receives a bending stress, so that a section of the binding means 16 guided inwards, into the press box, along the bottom 9 a in the guide unit 26 .1 to the nearest break point - the deflection point "U3" - also applied under voltage.

The setting agent is, according to that for the respective Baler type provided number, one or more times, like described above, inserted.

The process for setting a pressed bale "B" is briefly described below. After the shaft 2a of the pressing box 2 closes the front door is brought into an open position 8, which is a, the lower end 16 d of the Umreifungsdrahtes 16 of the wire holder 20 .1 dissolved and pulled forward. The portions of the binding agent, shown in FIG. 8a, positioned before and during the pressing in a guide unit 26 , are pulled by the pulling movement out of the latter 26 , into the grooves created in the bale "B" during pressing, shown in FIG. 8b. As can be seen from the illustrations in these two figures, the choice of a bi-concave cross section for the groove-like groove 26 c is particularly advantageous.

The sections of the binding agent 16 which are pulled forward are connected to one another. The wire end 16 d of the Umreifungsdrahtes 16 shown is pushed through the eyelet 16 c and pulled until on all sides of the finished bale, the portion concerned of the present Umreifungsdrahtes sixteenth Subsequently, while the section that is now behind the eyelet is still free, that is to say the remaining end region of the strapping wire, is twisted to form one or more loops, the section of the strapping wire 16 located at the front of the bale is twisted.

In Figs. 4 and 5 variants are shown at points or in sections c the offset arrangement of the groove-like groove 26. In Fig. 4, each guide unit 26 .5 has two sections and three contact points, namely the points "Uo", "U1" and "Un". The lateral offset of the middle contact or deflection point "U1" from the straight line "G" is directed towards the side walls.

In Fig. 5 are designated by the reference numeral 26 and shown .6 26 .7 possible variants of the portion-wise lateral offset of the groove-like groove 26 c.

In FIG. 6, the positioning of the inserted in a guide unit 26 .1 setting agent 16 is shown, with the inside of the base 9a is referred to. Due to the deflection at the contact or deflection points "Uo" to "Un", this area of the binding means 16 is divided into several sections "A1" to "An", the contact or deflection points "Uo" to "Un" alternating are arranged to the imaginary straight line "G". The bending stresses occurring in this entire area hold the setting means 16 more securely than previous solutions in its bottom-side guide unit 26 .

In the embodiment variant shown schematically in FIG. 7, the groove-like groove 26 c of a guide unit 26 .8 to said straight line “G” is only “P1” at certain points. , ., "Pn" laterally offset. This solution is preferred for rigid, flexible material, e.g. B. used in plastic tapes.

All of the features mentioned in the above description and which can only be gathered from the drawing are further components of the invention, even if they are not particularly emphasized and in particular are not mentioned in the claims. Reference number 1 baler
