Description

The invention relates to a container with a compression unit in order to compress material to be pressed and to transport it into an interior region of the container.

Such containers are used, for example, as waste and collection containers e.g. used for paper and cardboard as press material. The mounted or integrated compressor unit makes it possible to use the internal volume of the container as effectively as possible, so that the removal and emptying intervals for the container can be extended.

Such a container with a compression unit, also called a press container, is for example from the publication EP 0 472 870 B1 known. The container shown there is closed laterally, at the top and at one end and is filled through an opening on the opposite end. For filling, an upwardly open loading area is attached to the container, in which a linearly displaceable press plate is arranged, which pushes pressed material into the container like a slide and compresses it in the process.

When compacting over the pusher and thus remaining in the loading area, pressed material is lifted during the return movement of the pusher by a pivoted wedge so that it is thrown back onto the side of the pusher facing the container and can be grasped in a subsequent compression process. To move the press shield, a drive device acting centrally on it is provided, which can be designed as a rack or spindle or which is moved by a hydraulic cylinder.

The pamphlet DE 10 2005 054 986 B3 shows a similar arrangement, in which case two hydraulic cylinders or piston rods acting on the side of the press plate serve as a drive.

The disadvantage of the arrangements shown is that special precautions have to be taken in order to lift the pressed material lying behind the press shield so that it does not prevent the press shield from moving back.

Another disadvantage arises from the large overall length of the container with the loading area arranged at the front. As a rule, the maximum length of a container is determined by a length restriction during transport. Transport vehicles that pull up the container for transport have a specified loading length that must not be exceeded. The overall length of the loading area thus reduces the effectively usable length of the container for receiving the pressed material. Alternatively, provision can be made for the loading area to be designed so that it can be separated from the container, so that the container is transported without the loading area and thus could utilize the maximum transport length. In this case, however, the transport of the container to and from the container becomes significantly more complicated due to the need to separate or assemble the compressor unit.

From the pamphlets EP 1 385 695 B1 and DE 20 2010 012 354 U2 Alternative configurations of press containers are known in which a pressing process does not take place via a linearly displaceable press shield, but with the aid of pivotable wings or blades. With the script EP 1 385 695 B1 a press shovel is pivoted horizontally, whereas the writing DE 20 2010 012 354 U2 shows press wings pivoted about a vertical axis.

In these configurations of the press container, too, the loading area pre-assembled on the front of the container reduces the effectively usable length of the container for transport.

It is therefore an object of the present invention to create a container of the type mentioned at the outset which, while being easy to handle during operation and during transport, provides the largest possible usable internal volume for a given length.

This object is achieved by a container with the features of the independent claim. Advantageous refinements and developments are the subject of the dependent claims.

A container according to the invention of the type mentioned is characterized in that the compressor unit has a horizontally movable drawer with a bottom and an end wall which can be extended from a loading opening of the container, the end wall at least partially closing the loading opening when the drawer is retracted .

The e.g. The drawer, which can be extended from one end of the container, represents both the loading area and - with its end wall - the press shield itself. Retracting the drawer transports the pressed material into the container and compacts it. Because the loading area can be retracted, it does not contribute to the overall length of the container, unlike a fixed loading area in a transport state. Accordingly, the entire maximum length of the container can be used to hold pressed material. Since the entire drawer moves in and out, there is also no problem that the return movement of a press shield could be hindered by pressed material that is located between the press shield and a rear wall of a loading area.

In an advantageous embodiment of the container, the drawer has side panels which protrude laterally from the floor and are located in the interior of the container when the drawer is retracted. The side cheeks, which can be just as high as the front wall of the drawer, but can preferably also be made higher, prevent the pressed material from falling out of the drawer or being pushed out.

In a further advantageous embodiment of the container, the drawer is mounted on a wall of the container such that it can be moved horizontally via slide bearings. The plain bearings preferably comprise guide webs made of a plastic, preferably polyamide. The guide webs are furthermore preferably adjustable from the outside so that a guide play of the drawer can be easily adjusted and readjusted.

In a further advantageous embodiment of the container, the drawer can be moved via hydraulic cylinders which are arranged on the side of the wall of the container. Hydraulic cylinders represent a compact and powerful drive option for the drawer. Alternatively, other drives, e.g. Electrically operated spindle or rack and pinion drives are used.

In a further advantageous embodiment of the container, the front wall of the drawer extends over approximately a lower third to approximately a lower half of the container. In this way, it is possible to load the drawer at a height that is convenient for users. The loading opening advantageously has a height which corresponds approximately to the height of the front wall of the drawer in order to achieve compression of the pressed material as possible over the entire height of the loading opening.

In a further advantageous embodiment of the container, a pivotable loading shovel is arranged on an upper edge of the front wall of the drawer. The loading shovel preferably has a loading surface, side walls and a loading edge. The loading shovel can be swiveled open to load the container so that the loading area is as horizontal as possible away from the container. The loading shovel can e.g. be pivoted with respect to the drawer via a hydraulic cylinder. Pressed material can then either be thrown directly on the bottom of the drawer or conveniently deposited on the loading area for the user. Pressed material deposited on the loading area can e.g. be viewed and / or sorted, for example in order to remove material that is not suitable for the container and thus to be able to sort it out. Before the drawer is retracted, the loading shovel is swiveled up so that pressed material placed on the loading surface falls into the drawer and is transported and compacted when it enters the container.

In a further advantageous embodiment of the container, a vertically displaceable retaining slide is arranged in the area of the loading opening, which retainer can partially or completely close the loading opening. In a raised position of the retaining slide, the loading opening is preferably opened to the maximum in order to convey the pressed material through the loading opening into the interior of the container and to compact it there. In the retracted position of the drawer, the retaining slide can then be lowered and the drawer can be opened again when the retaining slide is lowered. The drawer extends through the retaining slide without the pressed material being moved out of the container.

In a further advantageous embodiment, the container has transport aids, in particular a transport carriage arranged in the floor area and / or transport rollers arranged in the floor area. Furthermore, a transport hook for pulling the container onto a truck and / or for maneuvering purposes is preferably arranged on the drawer. The transport hook can be mounted on the front wall of the drawer, for example. In particular if the drawer is equipped with a loading shovel, the transport hook is advantageously mounted in a foldable or pivotable manner. The mentioned transport aids make it possible to maneuver the container in the usual way or to pull it onto a truck for transport purposes.

An exemplary embodiment of a container 1 with an integrated compressor unit 10 is described in the figures. The figures show the exemplary embodiment in different states and from different viewing directions. In all figures, the same reference symbols identify the same elements. For the sake of clarity, not every element is provided with a reference number in every figure.

Figure 1 shows the container 1 in an isometric overall view. The container 1 has an essentially rectangular shape, with loading and unloading taking place via the end faces. The container 1 has frame elements 2 which carry a wall 3 which is closed at the top, bottom and to the sides and which give it increased stability. The frame elements 2 and the wall 3 are typically made of steel and are welded to one another. The wall 3 can also be conical on the sides and / or on the top of the container 1 in order to facilitate the emptying of the material received. A part of the wall 3, for example at the top, can also be designed to be pivotable or foldable in order to assist the emptying.

The ones in the Figure 1 The end face recognizable on the right-hand side represents an emptying opening 4 for the container 1. In the case shown, it is closed by means of a laterally hinged door. In an alternative embodiment, a horizontally pivotable flap, for example articulated along its upper side, can be used to close the emptying opening 4.

Transport aids 5 are arranged on the underside of the container 1, specifically a transport slide 51 with two runners in the present case, which can be designed, for example, in accordance with DIN 30722, parts 1-3, or comparable, possibly country-specific standards. As a further transport aid 5 are at the rear end, i. the end of the emptying opening 4 of the container 1, transport rollers 52 are arranged, which, for example, can also be designed in accordance with the DIN 30722 standard or comparable standards.

On the side of the container 1 there is an assembly space 6, in the present case in the form of a trough protruding slightly inward. In the unit space 6, a switch box 61 with electrical components and a hydraulic unit 62 are arranged. Control elements, for example (key) switches and / or signal lights, can also be present on or in the switch box 61. A flap, an attachment or also a blind can be provided in order to be able to close the unit space 6, which possibly offers additional protection against unauthorized operation and against vandalism.

Also arranged on the side of the container 1, in contrast to the unit space 6, however, on both sides, there is a hydraulic cylinder 7 in the lower region of the container 1, the piston rod of which, which is not visible here, runs within an exposed bulge 8 of the container 1.

The aforementioned compressor unit 10 is arranged in the area of the front end face of the container 1 opposite the emptying opening 4. It comprises an extendable drawer 11 in the form of a drawer, which in the illustration of Figure 1 is completely retracted into the container 1 so that it is one in the Figure 1 Not visible front loading opening of the container 1 closes.

In this in Figure 1 In the state shown, the container 1 is ready for transport. In order to be pulled onto a truck for transport, the container 1 has a transport hook 15 fastened to the drawer 11, which is the one in the example shown is designed as a swivel or folding hook, which is related to Figure 2 will be described in more detail.

Figure 2 shows the front area of the container 1 according to Figure 1 in an enlarged isometric view.

In contrast to Figure 1 is at Figure 2 the container 1 with the tray 11 extended. The drawer 11 has a bottom 111, side walls 112 and an end wall 113. The structure of the drawer 11 can also be seen in FIG Figure 5 14, which shows an isometric and longitudinal sectional view of the container 1 with the compression unit 10.

The drawer 11 is guided in the present case via a sliding guide. There are horizontal guide webs 9 arranged laterally in the container 1, which engage in longitudinal grooves in the side wall 112 of the drawer 11. The guide webs 9 can for example consist of a hard plastic that slides well on steel, for example polyamide. In the exemplary embodiment shown, the guide webs 9 are advantageously designed to be adjustable from the outside, so that a guide play can be set, e.g. To be able to compensate for wear of the guide webs 9. Further guide webs can be arranged on the bottom of the container 1, so that the drawer 11 slides on the bottom 111 of its bottom.

The drawer 11 is moved via the hydraulic cylinders 7 already mentioned, which are arranged on the side of the container 1. One end of the piston rods of the hydraulic cylinders 7, which are not visible here, engages a corresponding bracket on the rear end of the side walls 112 of the drawer 11. Said holder and the piston rods move under the bulge 8, so that there is no risk of pinching a user at this point. In order to prevent the pressed material from collecting in the bulges 8 and being moved in the direction of the hydraulic cylinder 7, a scraper 115 protruding into the bulge 8 is arranged at the rear end of the drawer 11. Towards the bottom, starting from the end of the bottom 111, a scraper 114 is attached to the drawer 11 in order to prevent the pressed material from getting into the area between the bottom 111, the drawer 11 and the bottom of the container 1.

Furthermore, in the Figure 2 to see that the transport hook 15 has been pivoted downwards. In one embodiment, this can be done manually but it is also conceivable to provide a further hydraulic cylinder via which the transport hook 15 can be pivoted.

The pivoting of the transport hook 15 is necessary in the illustrated embodiment in order to be able to pivot down a loading shovel 12 which is pivotably articulated at the upper end of the end wall 113. The function of the loading shovel 12 is in connection with the Figures 3a , b and 4th explained in more detail. In an alternative embodiment of the container 1, the drawer 11 can be equipped with a higher end wall 113, so that a loading shovel 12 arranged above can also be pivoted when the transport hook 15 remains in its transport position. In such an embodiment, the transport hook 15 can be fixedly mounted on the drawer 11 and need not be designed as a swivel hook. In further alternative configurations of the container 1, it can also be constructed without the loading shovel 12. In this case, too, it is not absolutely necessary for the transport hook 15 to be pivotable.

In the Figures 3a and b the container 1 is shown in isometric partial views with the loading shovel 12 pivoted down from different viewing directions. The loading shovel 12, which is mounted on the upper edge of the end wall 113 via hinges 13, is pivoted by means of a hydraulic cylinder 14 which is mounted on corresponding brackets on the end wall 113 and the loading shovel 12. As Figure 2 shows, corresponding brackets are provided on both sides of the end wall 113 or the loading shovel 12 in order to be able to use two hydraulic cylinders 14 if necessary, if the container 1 is to be suitable for heavier pressed material.

The loading shovel 12 again has a loading surface 121 and side walls 122 and a loading sill 123. In the in the Figures 3a and 3b The position shown of the loading 11 and loading shovel 12, the container 1 is ready to receive press material. This can either be thrown directly on the floor 111 of the drawer 11 or conveniently deposited on the loading surface 121 of the loading shovel 12 for the user. Pressed material deposited on the loading surface 121 can be viewed and / or sorted, for example in order to be able to remove material that is not suitable for the container 1 again.

After loading the drawer 11 or the loading area 121 or the loading shovel 12, the loading shovel 12 is moved back into the position shown in FIG. 2 via the hydraulic cylinder 14, whereby what is deposited on the loading area 112 Pressed material slips into the area of the drawer 11. The side cheeks 122 of the loading shovel 12, which pivot in an overlapping manner with the side cheeks 112 of the loading 11, prevent the inserted press material from falling laterally out of the container 1. The loading edge 123 prevents pressed material deposited on the loading area 121 from sliding forward from the loading area 121 when the loading shovel 12 is pivoted up.

After swiveling up the loading shovel 12 according to Figure 2 the drawer 11 is moved into the interior of the container 1 via the hydraulic cylinder 7, whereby the pressed material located in the area of the drawer 11 is transported into the interior of the container 1 and thereby compacted. The end wall 113 of the drawer 11 acts like a press shield or press ram.

The material to be pressed is moved into the interior of the container 1 through a loading opening of the container 1 which lies in the plane of its end face. This loading opening can extend over the entire cross section of the container 1, so that ultimately the entire end face of the container 1 serves as the loading opening. A disadvantage of such a configuration, however, is that the pressed material pressed into the container 1 can push itself out of the loading opening again when the drawer 11 is opened, in particular when the container 1 is in a higher loading state.

In the illustrated embodiment, not the entire cross section of the end face of the container 1 is used as the loading opening, but only a lower area which extends approximately over half the height of the container 1. The upper part is closed by a solid locking wall. This already effectively prevents pressed material from escaping from the loading opening. This is particularly true because the mass flow within the container 1 runs in the lower area in the direction of the emptying opening 4 and rolls upwards on the closed door or flap of the emptying opening 4 and moves forward again in the upper area towards the compression element 10. This upper, forward-moving mass flow is then stopped by the fixed closing wall on the front face of the container 1.

In the illustrated embodiment, a retaining slide 16 is additionally provided, which runs over the entire width of the loading opening 10 and can be moved vertically by means of a lateral guide 17 and a hydraulic cylinder 18. The loading opening is in a raised position of the retaining slide 16 maximally open, like the one in the Figures 3a and 3b can be seen. In this position of the retaining slide 16, the drawer 11 is retracted in order to convey the pressed material into the interior of the container 1 through the loading opening 9 and to compress it there.

In the retracted position of the tray 11, for example in Figure 1 is visible, the retaining slide 16 is then lowered, an edge arranged at its lower end and sawtooth-shaped edge conveying or cutting pressed material in the region of the retaining slide 16 further into the interior of the container 1. The drawer 11 is then opened with the retaining slide 16 lowered so that it extends without the pressed material being moved out of the container 1. This state is in the Figure 4 shown.

After the loading shovel 12 has been pivoted open again and the retaining slide 16 has been lifted, the container 1 is then again in the state shown in FIGS. 3a, b and is ready to receive further pressed material.

In the example shown, all movement processes are performed by hydraulic cylinders 7, 14, 18 which are fed by hydraulic unit 62. Alternatively, other drives can be used, for example spindle drives driven by electric motors.
