Description

cardboard and other dry paper compactor

The invention relates to equipment for processing cardboard or dry paper waste, and more particularly equipment of the type comprising a compacting device comprising a support structure having a lower face, via which the equipment rests on the ground, and four lateral faces, opposite in pairs, jointly delimiting a loading zone, a briquette press, arranged on a first of the lateral faces of the support structure, with an entrance to the loading zone and a thrust member, arranged on a second of the side faces of the supporting structure, opposite the first with respect to the loading area.

The term "cardboard" refers to a paper material with a basis weight greater than 224 grams per square meter and with greater stiffness than paper materials strictly speaking. This term also designates any object made with one or more sheets of cardboard, in particular packaging.

Cardboard material is very widely used today, in particular to make packaging. Among other things, the cardboard material is appreciated for its relatively low mass, compared to its mechanical strength, easy storage, which its sheet form gives it, economical and rather ecological manufacturing, as well as its versatility.

With the exception of very specific uses, cardboard boxes, especially cardboard packaging, cannot be reused. These boxes can nevertheless be recovered, because the cardboard material that constitutes them can be recycled or used as fuel. An obstacle to this recovery, however, is that the boxes generally occupy a relatively large volume, compared to their mass, which makes their handling and transport costly with regard to the mass of material to be recovered. And this cost must be related to the very low market value of this waste.

Where large quantities of cardboard waste are produced, such as in shops, warehouses or healthcare establishments for example, there is usually one or more pieces of equipment intended for the treatment of this waste, comprising at least one compacting device . One of the main functions of such a device is to reduce the volume of cardboard waste and package it in a form that is suitable following the recovery process.

These compacting devices include machines referred to as "compactors" in the art. It is most often a machine equipped with a jack system that pushes and compacts the material in a container, for example in the form of a bag or a bin. A service provider regularly removes full containers in order to recover their contents. Some compactors are equipped with a rotary motor system instead of the jack system. This is the case, in particular, of the compactor of the type known as "VALPAK" (registered trademark), from the company ALTERVAL.

Compaction devices also include so-called "bale" presses, which compact cardboard waste into a bale, i.e. a compressed and firmly tied mass of cardboard. The bales are then removed for recovery.

Baling presses include vertical presses, comprising a supporting structure having a lower face, through which the press rests on the ground, and four side faces, opposite in pairs, jointly delimiting a loading area. Presses of this type further comprise a pressure plate, mounted in translation on the support structure, and which descends from an upper face of the structure into the loading zone, crushing the cardboard waste which is there against the bottom of the structure. The entrance to a vertical press generally takes the form of an opening made on one of the side faces of the supporting structure and overlooking the loading area, opening through which the cardboard waste is thrown. In a vertical baler, bales are formed by stacking successive layers of compressed cardboard waste, each layer corresponding to one compression stroke of the platen. In a vertical baler, the loading area acts as the compression chamber for the baler.

Baling presses also include horizontal presses, comprising a supporting structure having a lower face, through which the press rests on the ground, and four side faces, opposite in pairs, jointly delimiting a loading zone and a chamber compression, one above the other. The entrance to the press takes the form of an opening made on the upper face of the supporting structure and leading into the loading area. The loading area is shaped like a hopper opening into the compression chamber, which allows cardboard waste to be thrown directly into the latter. A horizontally mobile carriage compresses the cardboard waste contained in the chamber onto the previous bale. After each compression stroke of the carriage, the entire volume of the chamber is available again. This chamber is then refilled by the boxes from the loading area, by gravity.

It is understood that unlike a vertical press, a horizontal press can be continuously fed with waste, including during the compression stroke of the carriage.

For some time now, presses of a new kind have appeared, capable of transforming cardboard waste into a plurality of compacted cardboard bricks, small in size compared to bales or compactor containers. These bricks, which are referred to as "briquettes" in the technique, are also much denser and hold together without the need for ties. On leaving the press, the briquettes can be stored, typically in a dumpster, before being evacuated to a recycling plant or a combustion power plant. The small size and high density of these briquettes greatly facilitate their storage, handling and transport, and therefore their recovery.

An example of a briquette press is the device known as the "Brickman 900" from the company Orwak.

This device comprises a support structure having a lower face, through which the equipment rests on the ground, and four side faces, opposite in pairs, jointly delimiting a loading zone. The device further comprises a compression chamber, arranged on a first of the side faces of the support structure, with a compression chamber open to the loading zone, and a thrust member, arranged on a second of the side faces of the structure carrier, opposite to the first with respect to the loading area, which will push the cardboard waste from the loading area to the compression chamber.

The Applicants have observed that in use, the briquette presses still have costs that are too high, when compared to the market value of the briquettes.

This is primarily due to the handling of cardboard waste. Typically, a collection container filled with cardboard waste, such as a cart or dumpster, is brought to the press, then each piece of waste is manually dumped into the loading area, practically one by one, before start the compaction process, once the loading area is full. Often, this loading area has a capacity less than the storage capacity of the container, so that the contents of the latter cannot be processed at once. We must then wait until the next compaction process.

Systems for overturning recovery containers, to dump their contents into the loading area of the press, exist, but they are essentially added to large capacity horizontal presses only. However, these presses have other drawbacks, such as a large footprint and a product of the treatment in the form of a bale, which makes the rest of the recovery process complex. In addition, such systems tend to increase the footprint of the press.

The Applicants have sought to improve the situation by proposing equipment for processing cardboard waste which makes it possible both to simplify the handling of the waste, in particular its collection, while maintaining a small footprint.

Equipment for processing cardboard or dry paper waste comprising a compacting device of the briquette press type is proposed. The compacting device comprises a supporting structure having a lower face, through which the press rests on the ground, and four side faces, opposite in pairs, jointly delimiting a loading zone of the press, a compression chamber, arranged on a first of the side faces of the supporting structure, open to the loading area, and a thrust mechanism, arranged on a second of the side faces of the supporting structure, opposite the first with respect to the loading area. The equipment further comprises at least one movable container, with at least two mutually opposite side faces delimiting between them a storage volume intended to receive cardboard boxes as waste. A first of these side faces has a window open to the storage volume. A pivoting flap is arranged at least partly on one of the second face of the support structure and the second face of the movable container. The loading area is arranged to accommodate the movable container in a removable manner. The pivoting flap is adapted to cooperate with the pushing mechanism, at least when the movable container is housed in the loading zone of the press, so as to push boxes from the storage volume of the movable container through the window of the latter .

Unlike conventional equipment, the proposed equipment does not require the handling of cardboard waste between its collection in an auxiliary trolley and its loading into the compacting device. Instead, place the full auxiliary carriage in the compartment provided in the briquette press. The pusher of the press cooperates with the pivoting flap of the auxiliary carriage to bring the cardboard waste which is in the storage volume to the compression chamber through the opening of the latter. After the auxiliary carriage has been received in the press housing, no waste handling is required for these to be transformed into briquettes. This results in a significant labor saving.

The storage volume of the auxiliary cart and the capacity of the bale chamber are matched to each other. Once the storage volume is full, there is a quantity of waste in relation to the processing capacity of the press. This results in a significant labor saving.

There is no need to dump the contents of the cart storage volume into the press loading area. In addition, the footprint of the press is not increased compared to conventional presses, this footprint can even be reduced.

The proposed equipment incorporates a briquetting press as a compacting device. In use, the equipment produces virtually no dust, unlike equipment that shreds waste to reduce its volume. Therefore, the proposed equipment has both a small footprint, compared to known equipment, and clean use.

A trolley is also offered as a movable container for the equipment offered. The movable container comprises at least two mutually opposite side faces, delimiting between them a storage volume intended to receive cartons as waste. A first of these side faces has a window open to the storage volume. A pivoting flap is arranged at least partly on the second face. The pivoting flap is capable of cooperating with the pushing mechanism of a briquette press, at least when the movable container is housed in a loading zone of this press, so as to push boxes from the storage volume through the window .

We finally propose a process for the treatment of cardboard or dry paper waste using the proposed equipment. This process includes the following steps:

- at least partially fill the storage volume of the movable container with cardboard or dry paper waste;

- accommodate the movable container in the loading area of the briquette press;

- actuating the pushing mechanism to push waste from the storage volume of the movable container to the compression chamber of the briquette press through the window of the movable container.

Reference is made to Figures 1 to 3.

They show a device for compressing cardboard waste in the form of a press 1.

The term "press" here designates a device comprising a loading volume for cardboard waste and capable of compacting this waste and conditioning it in a manner suitable for its future recovery. This term does not designate the part of the device that performs the compaction, but rather the entire device.

Press 1 is of the "briquette press" type: at the outlet of press 1, the cardboard waste is in the form of compressions resembling logs or short bricks, which are called "briquettes". For example, the briquettes that come out of the press 1 have a square section of eighty millimeters per side, a length of between one hundred and three hundred millimeters approximately and a density of the order of five hundred kilograms per cubic meter. Such briquettes can be used to produce recycled cardboard or as fuel (electrical yield: 1.29 kWh; thermal yield 2.30 kWh).

The press 1 comprises a generally parallelepipedal support structure 3, mainly consisting here of uprights and crosspieces in the form of sections of metal sections assembled to each other in a mechanically welded structure.

The carrier structure 3 has a first side face, or front face, occupied by a first frame, or front frame 5V, and a second side face, or rear face, opposite the first and occupied by a second frame, or rear frame 5R . The structure also has a third side face, or left face, occupied by a third frame, or left frame 5G, and a fourth side face, or right face, occupied by a fourth frame, or right frame 5D.

Structure 3 has a lower face through which structure 3 rests on the ground, and an upper face opposite the lower face. The lateral, lower and upper faces jointly delimit a free interior space which constitutes a loading volume intended to receive cardboard waste. The upper face is occupied by a fifth frame, or upper frame 5H.

The 5V front frame comprises a pair of uprights, namely a 7G front left upright, a 7D right front upright, which run parallel to each other, and a 9V front top cross member, which connects the upright left front 7G and the right front upright 7D between them, in the vicinity of their upper end. For example, these uprights have a length of about 2100 millimeters and the crossmembers about 1500. The 5V front frame has no other crossmember than the 9V front upper crossmember. The 5V front frame delimits a large opening in the front face of the structure 3 which gives access to a loading zone of the press 1 (also designated "loading volume"). This opening is free.

The rear frame 5R comprises a pair of uprights, a rear left upright 11G and a rear right upright 11D, analogous to the uprights of the front chassis 5V, and which extend parallel to each other, a rear upper crossmember (not visible in Figures 1 to 3), similar to that of the front frame 5V, and a lower rear cross member 9B which mutually connect the left rear upright 11G and the right rear upright 11D in the vicinity of their upper and lower ends, respectively.

The left frame 5G comprises the left front upright 7G, the left rear upright 11G and a left upper cross member (not visible in Figures 1 to 3) which connects the left front upright 7G and the left rear upright 11G to one another. other, near their upper extremity. The left frame 5G also includes a left lower cross member 13B, which connects the left front upright 7G and the left rear upright 11G to each other in the vicinity of their lower end. The right frame 5D comprises the right front upright 7D, the right rear upright 11D and an upper right cross member 13D, similar to the upper left cross member, and which connects the right front uprights 7D and right rear uprights 11D to each other, here near their upper end.

The lower end portions of the front right 7D, front left 7G, rear right 11D and rear left 11G uprights form feet through which the structure 3 and the press 1 rest on the ground. These feet delimit an open lower face of the supporting structure 3.

The 5H top frame includes the front 9V, rear, right 13D and left top rails.

The 5V front frame is free, leaving a wide opening in the structure 3 to reach the loading area of the press 1.

The left frame 5G carries a ram compaction mechanism 14, the compression chamber of which is open to the loading area. The rear frame 5R supports, in part at least, an electrical box 15 and a hydraulic unit 17 as well as the control devices (not shown) allowing the press 1 to operate automatically.

The 5H upper frame is open to the loading area. Here, the press 1 further comprises a container forming a reservoir 19 supported by the upper frame 5H. The container-reservoir 19 has a lower face in shape correspondence with the upper frame 5H. Here, the container-reservoir 19 has the general shape of a rectangular parallelepiped.

On the right frame 5D is pivotally mounted a door 21, here on the right rear upright 11D. The door 21 is movable between a closed position, visible in Figures 1 and 2 in particular, where the door 21 fills most of the right frame 5D, and several open positions, where the door 21 releases the right frame 5D, as on the For example.

Door 21 supports a push mechanism capable of acting in the loading area of press 1, at least when door 21 is in the closed position. This mechanism here takes the form of a rocker arm assembly 23. The rocker arm 23 comprises a cylinder 230 and a lever 232 hinged to the door 21 and pivotable relative to this door 21 under the effect of the cylinder 230. Here, the lever 232 takes the form of a frame consisting of two rods 234 hinged at one of their ends to an upper portion of the door 21 and supporting at their opposite end a contact roller 236. The rods 234 are interconnected by a crosses 238.

The press 1 further comprises a duct 25, the section of which corresponds to that of the briquettes and which connects the outlet of the compacting mechanism to the interior of the container-reservoir 19. The duct 25 opens into an upper zone of the container-reservoir 19, away from the upper frame 5H, here on one side of this container 19 close to the left frame 5G.

Reference is made to Figures 4 and 5.

The loading area of the press 1 is arranged in a housing whose size and shape are adapted to receive an auxiliary carriage 100.

The general shape of the auxiliary carriage 100 corresponds to that of the loading volume, here generally parallelepipedic. The dimensions of the 5V front frame are adapted to the overall length of the carriage 100. The carriage 100 can reach the loading area through the 5V front frame of the structure 3 because the latter is free. The dimensions of the right frame 5D are adapted to the overall width of the carriage 100. The carriage 100 can also reach the loading area through the right frame 5D, when the door 21 is open, as is the case on the .

When carriage 100 is in the loading area, carriage 100 contacts both rear bottom cross member 9B and left bottom cross member 13B. The door 21 can close the right frame 5D, while the carriage 100 does not protrude from the front frame 5V. The lower rear cross member 9B and the lower left cross member 13B position the carriage 100 in the loading zone. This zone is adjusted to the dimensions of the carriage 100, in particular to its size. This results in a footprint of the press 1 that can be described as optimized.

Reference is made to Figures 6 to 13.

The auxiliary trolley 100 comprises a horizontal supporting structure and a vertical supporting structure which rises from the horizontal structure. The vertical structure has a mutually opposite front face and a rear face as well as a mutually opposite left side face and a right side face. These side faces jointly delimit an interior volume of the trolley 100 intended to serve as a storage area for the collection of cardboard waste.

The horizontal structure comprises a rectangular frame 102, produced here by assembling sections of metal profile into a mechanically welded structure. The frame 102 comprises a pair of long sections 104 and a pair of short sections 106 each connecting the long sections 104 to each other in the vicinity of one of their respective ends. Cart 100 includes steerable wheels 108 on which frame 102 is mounted.

The vertical structure includes a front frame 110 which rises from one short section 106 of the frame 102 and a rear frame 112, opposite the front frame 110 along the length of the frame 102 and which rises from the other short section 106 of the frame 102.

The front frame 110 comprises a pair of uprights, namely a left front upright 110G and a right front upright 110D, a front upper cross member 120H, similar to a short section 106, which connects the right front upright 110D and the left front upright 110G to each other in the vicinity of their upper end, and one of the short sections 106, which connects the right front upright 110D and the left front upright 110G to each other in the vicinity of their upper end.

The rear frame 112 comprises a pair of uprights similar to the uprights of the front chassis 110, namely a left rear upright 112G, a right rear upright 112D as well as a short section 106 of the frame 102 and a rear upper cross member 120H similar to this section which connect the left rear upright 112G and the right rear upright 112D to each other, in the vicinity respectively of the lower and upper ends of these uprights.

One large section 104 of frame 102, right front upright 110D and right rear upright 112D together form a right frame 118D which rises from frame 102, while the other large section 104 of frame 102, right front upright left 110G and the left rear upright 112G form a left frame 118G. The right frame 118D and the left frame 118G each further comprise an upper crosspiece 116H which connects the front and rear uprights of the frame to each other, away from their upper end. As a variant, these upper crosspieces 116H can connect the front and rear uprights near their upper end. Here, the upper crosspieces 116H of the right and left 118D and 118G frames are at the same level. As a variant, these crosspieces 116H can be at different levels from each other. The upper crosspieces 116H each form, in combination with a long section 104 of the frame 102 and a corresponding portion of the front and rear uprights, a frame in the lower part of the carriage, or lower frame.

The side faces each include a first panel, or bottom side panel 124 which fills the bottom frame of right frame 118D and left frame 118G, respectively. These side faces each further comprise a second panel, or upper panel 126, which fills the upper part of the right 118D or left 118G frame, from the upper crosspiece 120H to near the upper end of the uprights. Each top panel 126 is pivotally mounted on a top rail 116H, thus forming a folding flap. Each top panel 126 can take, relative to the frame on which it is mounted, a raised position, in which the top panel 126 closes the upper part of the frame, and a folded position, in which the panel releases this part. In the folded position, access to the storage area is facilitated in that the upper part of the chassis offers an opening at human height. The folding nature of the upper panels 126 is optional: these upper panels 126 can be fixedly mounted relative to the frame, or only one of these panels can be pivotally mounted.

The front frame 110 also carries a pair of intermediate crosspieces, namely a low intermediate crosspiece (not referenced) and a high intermediate crosspiece 128H which each connect the right front upright 110G and the left front upright 110G to each other, at a distance respectively from their lower and upper ends. A lower frame is thus formed, comprising a short section 106 and the lower intermediate crosspiece, an upper frame, comprising the front upper crosspiece 120H and the upper intermediate crosspiece 128H, and an intermediate frame, between the lower intermediate crosspiece and the intermediate crosspiece high 128H.

The lower frame is filled by a third panel, or lower front panel 130, fixedly mounted relative to the front frame 110. Here, the lower front panel 130 is solid. The upper frame is filled by a fourth panel, or upper front panel 132, fixedly mounted relative to the front frame 110. Here, this upper front panel 132 is perforated, in particular mesh. The intermediate frame delimits an opening on the storage area of the trolley 100 at the front of the trolley 100. A fifth panel, or intermediate front panel 134, whose shape and dimensions correspond to the intermediate frame, is mounted in translation on the chassis front 110. This intermediate front panel 134 is movable between a raised position, visible in Figures 8 and 9, where the intermediate front panel 134 fills the intermediate frame and closes the opening on the storage area, and a lowered position, as in Figures 7, 10 and 13, where the intermediate front panel 134 third panel releases this opening. Here, the intermediate front panel 134 is perforated, in particular screened.

Trolley 100 also includes a guide ramp 136 which occupies the bottom of the storage area of this trolley 100. Ramp 130 is mounted across frame 102, at a distance therefrom. The ramp 130 rises from the short section 106 of the rear frame 112 to the lower intermediate crosspiece of the front frame 110 according to a curved profile, approximately in an arc of a circle. In other words, the ramp 130 leads from the bottom of the rear face of the carriage 100 to the opening provided in the front face of the latter.

This ramp 130, and more generally the bottom of the carriage 110, can be mounted on at least some of the frames by means of shock absorbers, such as compression springs for example. This makes it possible to cushion the fall of briquettes in the carriage 100.

The carriage 100 comprises a rear flap 140 pivotally mounted on the rear frame 112, on the upper crosspiece 120H. The rear flap 140 can be moved between a substantially vertical position, where the rear flap 140 fills the rear frame 112 (FIGS. 6, 8 and 9), and an extreme inclined position, where the rear flap 140 is across the area storage, a lower portion of the rear flap 140 being at the level of the lower intermediate crosspiece of the front frame 110 and in the vicinity thereof (FIGS. 10 to 13). In the rotary movement which leads the rear flap 140 from its vertical position to its extreme position, the lower portion of this rear flap 140 closely follows the ramp 130, which allows the flap 140 to bring the cardboard waste which is in the storage area up to the opening of the intermediate frame of the front chassis 110.

The rear flap 140 here carries a corner 142 formed of an upper surface 142S and a lower surface 142I which project from a panel 144 of the flap 140. The lower surface 142I is inclined with respect to the panel 144 of the rear flap 140 in such a way that this lower surface 142I is substantially vertical when the rear flap 140 is in the extreme position. Preferably, this lower surface 142I is, in this extreme position, slightly inclined with respect to the vertical in a negative manner. This tends to push the cardboard waste to the end of the stroke of the rear flap 140. The upper surface 142S is inclined in such a way that it is positively inclined relative to the horizontal when the flap 140 is in the extreme position.

In the vicinity of its lower end, the rear flap 140 is equipped with a bar forming a scraper 146. The scraper projects from the panel 144 of the rear flap 140 in an inclined manner, so that in the extreme position the scraper 146 is substantially horizontal. The blade 144 cooperates with the ramp 130 to scrape the cardboard waste from the storage volume. At the end of the stroke of the rear flap 140, when the latter is in the extreme position, the scraper 144 fills the space between the opening in the front frame 110 and a lower end portion of the rear flap 140.

The opening in the front frame 110, delimited by the intermediate frame, is arranged at a height such that this opening is opposite the opening on the compression chamber of the press 1 when the carriage 100 is housed in the area loading of this press 1. The shape and dimensions of the intermediate frame also correspond to the shape and dimensions of the opening of this compression chamber.

One or more carriages of the auxiliary carriage 100 type, described in relation to FIGS. 6 to 13, can be used in combination with a press of the press 1 type described in relation to FIGS. equipment adapted to the treatment of cardboard waste, a use of which is now described.

One or more auxiliary trolleys 100 can be used to collect cardboard waste in their storage area. Because of their small size and their maneuverability, there are few constraints as to the positioning of these trolleys 100 in an establishment. In particular, carriages 100 can be positioned as close as possible to where the cardboard waste is produced, regardless of whether this place is far from the place of installation of the press 1 or not.

When the storage area of an auxiliary carriage 100 is full, the auxiliary carriage 100 is taken to the press 1 and placed in the loading area of this press 1 arranged in a housing, as shown in . In a way, the loading area of the press 1 includes the storage volume of the carriage 100.

The front face of the carriage 100, with the front frame 110, which has the opening delimited by the intermediate frame, is opposite the left frame 5G of the press 1. The rear face of the carriage 100, occupied by the rear flap 140 , is facing the door 21 and the rocker arm assembly 23. The carriage 100 can reach the housing of the press 1 through the front frame 5V of the structure 3 of the press 1 or, alternatively, through the right frame , once door 21 is open. The rear flap 140 is in a vertical position. The carriage 100 is used to store cardboard waste when this carriage 100 is outside the loading zone, and as a receptacle or hopper when it is in this zone.

When the Cart 100 is used as storage, the mesh panels can be folded down to facilitate the loading of cardboard waste. These panels are reassembled while the cart 100 is being driven to press 1 as well as during the emptying phase of these boxes in press 1.

When the trolley 100 is used as a receptacle or hopper, the mesh panels are folded down to allow loading of the waste into boxes and/or a continuous supply of waste.

This ability to continuously load boxes into the press 1 strongly distinguishes the latter from presses of the state of the art. On the one hand, not all presses allow such loading, on the other hand, those that do have such a large footprint that in practice, they are not used indoors.

If necessary, the door 21 is closed. The cylinder 230 of the rocker arm assembly 23 is actuated. The rocker arm 232 pivots relative to the support structure 3 of the press 1 until the roller 236 comes into contact with the shutter 140. The rod of the actuator 230 of the rocker arm 23 continues its extension and the arm 232 of the rocker arm 23 continues its pivoting movement relative to the structure 3. In doing so, the arm 232 drives the rear flap 140 of the carriage 100 in a movement of pivoting relative to the rear frame of the carriage 100. The pivoting movement of the rear flap 140 continues until the rear flap 140 reaches its extreme position, as in Figures 15 and 16.

The space between the intermediate frame and the rear flap 140 is filled by the blade 144 and the lower surface 142I of the wedge is substantially vertical. In this movement, the rear door 140 pushes the cardboard waste which is in the storage volume of the carriage 100 through the opening of the carriage 100 and, from there, through the opening of the compression chamber which faces him.

Reference is made to Figures 16 and 17.

The opening towards the compression chamber is controlled by a guillotine assembly 27. The guillotine 27 comprises a guillotine plate 270 slidably mounted on the left frame 5G and a cylinder 272 whose rod moves the plate 270 of the guillotine 27 with respect to this 5G chassis enters a high position, visible on the , where the plate 270 releases the opening on the chamber 140 of the compression assembly 14, and a low position, visible on the , where the plate 270 closes this opening.

The rod 1440 of the cylinder 1420 of the compression assembly 14 is retracted, which frees the chamber 140 for cardboard waste. The actuator 272 of the guillotine assembly 27 is actuated, which moves the guillotine plate 270 in a downward translational movement. In doing so, the guillotine plate 270 compresses the cardboard waste present in the chamber 140 for the first time and cuts those of this waste which protrude from the chamber 140 into the storage volume of the trolley 100. The guillotine plate 270 closes access to the chamber 140. We are in the state of figures 17 and 18. The cylinder chamber 1420 is arranged parallel to the left frame, to reduce the size of the press 1.

Finally, the actuator 142 of the compression device 14 is actuated. The rod 144 compresses the cardboard waste from the chamber 140 against a pair of tabs 146 arranged at the outlet of the chamber 140 to help compress the briquette along its length. This compression is also done against the previous briquette. We are in the state of .

Due to the pressure exerted by the rod 144 of the cylinder 142 of the compression assembly 14, it leaves the chamber 140 and enters the conduit 25 a continuous bead of compressed cardboard material. Close to the exit of the chamber 140, the duct 25 is shaped in a bent portion 250 which contributes to cutting the continuous bead into elements, the briquettes.

These briquettes are pushed into the conduit 25 by the following briquettes, until they fall into the container-reservoir 19 ( ).

We refer to the .

The duct 25 extends essentially in a plane parallel to the left face of the support structure of the press 1. After the bent portion 250 which is close to the outlet of the compacting device 14, the duct 25 s extends along a rectilinear section 252 arranged substantially vertically until it reaches the height of the container-reservoir 19. There a second bend 254 connects the vertical section 252 to a second rectilinear section 256 arranged horizontally and which leads close to the container-reservoir 19 From there an end section 258 of the conduit 25 opens into the container-reservoir 19.

The underside of the reservoir container 19 is open to the upper frame 5H. A hatch assembly 31 is arranged across the upper frame 5H, the state of which, open or closed, controls the communication between the interior of the tank 19 and the loading area of the press 1. The hatch assembly 31 comprises here a pair of panels 310 each mounted to pivot relative to the upper frame 5H. Each of the panels 310 can assume a closed position ( ) in which the panel 310 fills, at least in part, the upper frame 5H and an open position ( ), in which the panel 310 releases this frame 5H. The panels 310 are each movable under the action of a respective cylinder 312 of the hatch assembly 31.

With reference to the , for emptying the container-reservoir 19, one can place a mobile tray 33 in the loading area of the press 1, here a tray similar to a trash can, then actuate the cylinders 312 of the hatch assembly 31 to release the upper frame 5H. The briquettes from container-reservoir 19 then flow into tank 33 by the effect of gravity.

We refer to the notably.

A carriage of the auxiliary carriage 100 type can be left in the loading volume of the press 1, preferably with the flaps in the folded down position. This also makes it possible to collect cardboard waste where press 1 is located.

We have just described a piece of equipment for processing dry cardboard or paper waste comprising a compacting device formed from the briquette press comprising a support structure 3 having a lower face, through which the press rests on the ground, and four side faces, opposite in pairs, jointly delimiting a loading zone of the press, a compression chamber 14, arranged on a first of the side faces of the support structure, open to the loading zone; a thrust mechanism, arranged on a second of the side faces of the support structure, opposite the first with respect to the loading zone. This equipment further comprises at least one movable container, in the form of the trolley 100, with at least two mutually opposite side faces, delimiting between them a storage volume intended to receive boxes as waste, a first of these side faces having a window open onto the storage volume, and a pivoting flap, arranged at least in part on one of the second face of the supporting structure and of the second face of the movable container, while the loading area is arranged so as to house the movable container in a removable manner and the pivoting flap is adapted to cooperate with the pushing mechanism, at least when the movable container is housed in the loading zone of the press, so as to push boxes from the storage volume of the movable container through the window of the latter.
