Abstract

The invention relates to a press for making bales of waste, in particular waste such as commercial or industrial waste, domestic waste or household waste. It is of the compacting piston (5) and discharge piston (13) type. The compaction piston (5) can slide in a compaction chamber (Cc) in order to be able to compress the waste and the discharge piston (13) can slide in order to be able to push out of the chamber (Cc) the compacted waste bales by the compacting piston (5). According to one characteristic of the invention, the barrel (12a) of the discharge piston (12) can slide along the same axis of sliding of the piston (13) in order to be able to take two positions, one in which it can be locked and where the piston (13) can act normally on the waste bales to extract them from the compaction chamber (Cc) and the other where, with the cylinder (12) retracted, the piston (13) is level opening of the door (14).

Description

The present invention relates to a press for making bales

  waste, including waste such as commercial or industrial waste,

  household waste or household waste.

  Presses for making waste bales are already known and the French patent document No 2 224 372 La will be cited as an example of such a press.

  press described in this document, suitable for compacting

  tage of non-metallic waste such as waste paper and household waste essentially comprises a compaction chamber provided with an opening through which the waste is introduced, a piston serving to subject the waste to compression producing bales of

compacted waste.

  The bales come out of the compaction chamber

  one after the other along the longitudinal axis of the channel.

  A particular problem with this type of press is that the operations of separating the bales from one another, bringing them to a given dimension and binding them entail

  the implementation of a complex structure of the machine.

  Also known from document EP-

  A-150 687 a press intended for the compaction of waste such as textile scraps, etc. This press differs from the previous one in that it comprises a compacting piston and a discharge piston whose sliding axes are perpendicular to it one compared to the other This simpler configuration makes it possible to make bales of equal dimensions and

facilitate ligating.

  The cost of a waste press is relatively high and, for certain structures, represents a prohibitive investment. Furthermore, waste does not need to be compacted immediately after its production, so that such a press remains

  works in small stages of time In these cir-

  constants, it can be interesting to have a mobile press which works consecutively on several

  sites, which pays for its investment.

  It is therefore possible to provide a vehicle provided with a press and, for the reasons mentioned above, a press of the type with two pistons perpendicular is preferred.

between them.

  The problem which the invention proposes to solve is that of the adaptation of such a press on a vehicle which must not exceed a given gauge for

be able to drive on the road.

  The solution proposed by the invention consists in providing a waste press of the compacting piston and evacuation piston type and intended to be mounted on the platform of a vehicle capable of traveling on the road, said compacting piston being able to slide in a longitudinal compaction chamber relative to the direction of advancement of said vehicle so as to be able to compress the waste in said chamber and the evacuation piston being able to slide, under the effect of a jack, transversely to said compaction chamber in order to be able to push out of said chamber, by opening a door, the compacted waste bales

by the compacting piston.

  According to a characteristic of the invention, the barrel of said evacuation cylinder can slide along the same sliding axis of the evacuation piston in order to be able to take two positions, one in which it can be locked and where the piston acts normally on the bales of waste to extract them from the compaction chamber and the other o, the cylinder being retracted, the

  piston is located at the door opening.

  According to another characteristic of the invention, the barrel of the evacuation cylinder is secured to a bed base guided in translation by rods which can slide in

  fixed journals with respect to said chamber.

  The characteristics of the invention mentioned above

  above, as well as others, will appear more clearly

  on reading the following description of an example of

  realization, said description being made in relation

  with the accompanying drawings, among which: Fig 1 is a front view of a vehicle equipped with a press according to the present invention, Fig 2 is a top view of a press according to the invention, Figs 3 and 4 are sectional views along plane III-III of FIG. 2 of a press according to the invention,

  the compacting piston being in two different positions

  annuities, and Figs 5, 6 and 7 are sectional views along the plane V-V of Fig 2 of a press according to the invention, the evacuation piston and the evacuation cylinder being

in different positions.

  The vehicle shown in Fig 1 is essen-

  partly consisting of a semi-trailer 100 coupled to a

tractor 200.

  On the platform 110 of the semi-trailer 100, is mounted, at the rear, a pivoting crane 120 provided with a

  grapple 121 at the free end of an articulated arm 122.

  On platform 110 proper, is mounted a

  waste press 130 which is described in more detail below

  below in connection with FIGS. 2 to 7 At the front of the semi-trailer 100 are mounted control members comprising a system for producing pressurized oil for controlling the various jacks of the crane 120 and of the press 130 and a control cabinet 150 of the various processes executed in particular by the press 130 The semi-trailer 100 is also equipped with retractable feet 160 allowing it to have a good seat

on the ground in working position.

  There is shown in Fig 2, top view, the

  press 130 which equips the semi-trailer 100 of FIG. 1.

  We see in this Fig 2, represented by a rectangle, the platform 110 of the semi-trailer 100 The press 130 essentially comprises a compaction assembly 10 and a discharge assembly 20 placed perpendicularly to one another. other, the first being in the longitudinal axis of the semi-trailer 100 and the other placed at

the rear transversely.

  The press 130 is shown in longitudinal section in Figs 3 and 4 and in cross section in Figs 5 to 7 In these Figs, we see that it has a main body 1 mounted directly on the frame 2 of the press The body 1 forms a first longitudinal channel 3, for example of rectangular section, in which can slide, under the effect of a double-acting cylinder 4 whose barrel 4 a is integral with the chassis 2 of the press, a

  piston 5 of the same section as the channel 3 (Figs 3 and 4).

  Downstream of the front face of the piston 5, the channel 3

  forms, with a rear wall 6, a compacting chamber

  stage Cc, the volume of which can vary as a function of the position of the piston 5 in the channel 3 FIG. 3 shows the compacting assembly with the piston 5 retracted and, in FIG 4, with the piston 5 at the end of

race.

  A hopper 7 whose opening 7 a is turned towards the

  high at its exit 7 b which gives onto the compacting chamber

floor Cc.

  When the piston 5 is in the retracted position (Fig 2), the waste is loaded by the hopper 7 by means of the grapple 121 of the crane 120 (Fig 1), then the jack 4 is controlled so that the piston 5 slides in order to ensure the compaction of this waste in the compaction chamber Cc At the end of its travel, the waste forms a compacted bale represented, in FIG. 4, by means of a

square with a cross.

  The main body 1 has a second channel 11 (Figs 5 to 7) which, transverse, is perpendicular to the first channel 3 Inside the second channel 11, can slide, under the effect of a double-acting cylinder 12, a second piston 13 The front wall of the piston 13, the front wall of the piston 5, the rear wall 6, and the upper and lower walls of the body 1 form the chamber intended to receive the compacted bales and to

  allow their evacuation by a retractable door 14.

  We see, in Fig 2, that the retractable door 14 is sliding back and forth by means of a jack 15 whose barrel is secured to the frame of the press 130 and that it is guided in its movement by walls

side 16.

  The barrel 12a of the actuator 12 is integral with a bed base 17 intended to slide, for example by means of guides 18, along the sliding axis of the piston 12 The guides 18 consist of rods mounted integral with the bed base 17 and which can slide in pins 19 integral with the

body 1 of the press.

  Thus, the barrel 12 a of the cylinder 1 can take two positions: a first where it is offset laterally with respect to the longitudinal axis of the compaction chamber Cc (Figs 5 and 6) and another where it is at

  otherwise retracted to this chamber Cc (Fig 7).

  The barrel 12a of the jack 12 is held in the first position by means of a keying 20 provided on at least one of the pins 19 and immobilizing the bed base 17

in its remote position.

  At the exit from the chamber Cc, there is provided a ligating device 21 intended to pass around the compacted bale several distributed metallic straps

along its length.

  A device 22 for receiving the compacted bales is provided under the body 1 It is for example composed of two forks 22 a supporting a plate 22 b intended to receive the bales of compacted waste extracted from the

  chamber 11 The forks 22 a can slide transversely

  dirty to store under body 1 (Fig 7).

  The bales compacted on the device 22 can

  be removed by the grapple 121 of the crane 120.

  During the compaction phase carried out by the piston 5, the piston 13 of the evacuation assembly is in the retracted position (Fig 5) Once the compaction is complete, the door 14 is retracted and the actuator 12 is controlled so that the piston 13 pushes the waste ball

  compact towards the outside (Fig 6).

  At the same time as the ball is extracted, the ligating device 21 is started to perform the ligating of the ball The ball then rests on the plate 22 b of the device 22 from which it can

be removed by crane 120.

  Once the compaction and evacuation operations

  cuation of the balls made, the guides 18 are released from the keying 20 allowing the bed base 17, and consequently the piston 12, to take their second position (Fig 7) The rod of the jack 12 is retracted and the piston

13 is pushed against door 14.

  At this time, the transverse dimension of the press is at its minimum It can be less than or equal to

  the width normally authorized on the road.
