Description

waste collector

description

The invention relates to a waste collector with a frame and a container arranged therein in a removable manner, with a bottom and an opening opposite the bottom, and with a press ram assigned to the container, which is connected to an actuator via at least one linkage and parallel to the bottom of the container can be shifted into a filling layer releasing the opening and into a compacting layer immersed in the container.

Such a waste collector is known from DE 75 17 725 U.

CH 700 180 B1 discloses a waste bin with a bellows with a base plate, a cover and a unit that generates a vacuum. The cover forms a closed chamber with the bellows, from which the air can be sucked out by the unit that generates a vacuum. Due to the drop in pressure in the bellows, the ambient pressure pushes the plate of the bellows in the direction of the cover. The air from the environment can flow in through holes in a bottom of the waste bin, while the bellows is displaced towards the lid, in order to compress the waste in the bellows. In this case, the sealing required to generate the negative pressure proves to be problematic.

DE 28 14 791 C2 discloses a waste container, in particular for receiving and pressing paper. A cover that can be pivoted about a horizontal axis for closing the container opening includes a cover that fits into the container opening protruding ram for compressing the waste. When the lid is closed, which is pivoted into an open position by means of a foot operator via a lever linkage, the waste is pressed as soon as it reaches a specified filling level, with the press ram being firmly connected to the lid and thus posing a risk of injury to people is given to the user when closing, since it cannot be ruled out that, for example, there is a hand between the lid or the ram and the container, and on the other hand, the ram must be dimensioned in its base area much smaller than the cross-section of the container so that it can Pivoting can get into or out of the container, as a result of which uncompressed waste can accumulate in the edge regions between the ram and the container, which can also get out of the container when the lid is pivoted to open it.

Furthermore, DE 77 13935 U and WO 2006/026822 A1 show waste bins with a press ram.

The invention is based on the object of creating a waste bin of the type mentioned at the outset which, with a relatively simple structure, ensures reliable functioning, with waste being ejected when it is opened.

According to the invention, the object is achieved in that an insertion opening is arranged at the front and a closure means coupled to the actuator releases the insertion opening in the filling position of the press ram.

Since the ram is displaced parallel to the bottom of the container, it can be adapted to the cross-section of the container with a relatively small clearance or small circumferential gap. As soon as the loose waste present in the container of the waste collector, in particular paper, for example paper towels, fills the container to a certain extent or a certain filling level is reached, the ram takes effect by pressing or compressing the waste into the container . In the same way, the ram serves as a kind of cover for the waste collector in the compacted position. Will waste in the the opening given the container releasing filling position of the ram in the waste collector and then shifted the ram into its compaction position in the container, then the waste is reliably pressed into the container.

The actuator provided for moving the ram can be designed, for example, as a pedal or other foot actuator or a hand lever. The person skilled in the art will choose depending on the design of the waste bin, for example depending on its size or installation on the floor, on a shelf or hanging on a wall.

The waste can be compacted, for example, due to the weight of the press ram, by its forced displacement by means of the actuator connected via the linkage, in particular under the additional effect of at least one spring element or the like. The linkage can have any convenient geometry.

The waste collector according to the invention is suitable, for example, for receiving relatively easily compressible waste, such as paper, in particular towels such as are offered in toilets, or plastic packaging. This avoids overfilling of wastepaper baskets with the associated contamination of the environment and the correspondingly higher cleaning effort, especially in toilets or washrooms.

For emptying, the container can be removed from the waste collector, for example at the back. Of course, removal from the side or from above or from the front is also possible. The container can also be made of cardboard, preferably with a coating, or have a removable insert made of cardboard or paper, so that the container or the insert can be disposed of together with the compacted paper contained therein, in particular for recycling.

By the closure means a risk of injury to a user when compacting the waste by means of the ram is largely excluded, since the Injection opening is opened when the ram is moved out of the container by the closure means for throwing in waste and is closed during the lowering of the ram in the direction of the container. Here, the closure means can run ahead of the ram to ensure that there are no objects or extremities of the user in the danger area. Of course, the closure element can also block the movement of the ram. The closure means can be flap-like or slide-like or the like.

In an embodiment, the container is coupled to the actuator in such a way that it is displaced in the compaction position in the direction of the ram and in the filling position in the opposite direction to the ram. When the actuator is actuated, the container and the ram move in opposite directions, the height of the container being displaceable and greater compaction being able to be achieved with a constant stroke of the ram. Since the stroke for compacting the waste can be generated by the press ram and the container, the waste collector can have a relatively small overall height.

According to a further development, the frame comprises at least one base plate, a cover, two side walls with guides for the rods and a front plate with the insertion opening. The closure means can be mounted on the frame and/or the front flap for opening and closing the insertion opening.

The closure means expediently comprises interconnected lamellae which are mounted on the side walls in such a way that they are guided at least partially parallel over the ram in the filling position and parallel to the front panel in the compacted position. The closure means is therefore designed like a roller shutter. The total height of the waste collector can be kept relatively low due to the deflection into the parallel position guided over the press plunger or the opening of the container. In one embodiment, mechanical or electromechanical anti-trapping protection is assigned to the locking means and/or the ram. The anti-trapping protection is intended to prevent the limbs of a user of the waste collector from being trapped in the area of the locking means and/or the ram in the event of incorrect operation, with one or the other of course Component can be blocked in its displacement in such a way that the displacement of the other component is prevented due to a coupling.

The mechanical anti-trapping device expediently comprises at least one coupler which has two limbs and is pivotably mounted on the frame, one limb being coupled to one end of the closure means and another limb to the linkage. The coupler is connected to the linkage in such a way that when the actuator is acted upon, the ram can be moved almost completely from its compacted position into its filling position, until the closure means is moved to open the insertion opening. When the actuator is released, the insertion opening can first be closed by means of the closure means and then the ram is shifted from its filling position to its compaction position, with a mechanical coupling, for example by means of a pin guided in a groove of the coupler, raising the closure means to open the insertion opening is prevented.

The electromechanical anti-jamming device preferably includes an electronic controller, which is coupled to limit switches for detecting the two end positions of the closure means and electromechanical actuators for locking the press ram in its two end positions. Of course, in addition to a computer module, evaluation and, if necessary, storage means are also assigned to the controller. Furthermore, a power supply is realized either by means of a power pack or a battery. The limit switches can, for example, have a capacitive or inductive effect and/or comprise light barrier arrangements. For example, the actuators may include solenoids with displaceable locking pins. In order to reliably hold and evenly move the ram, which is preferably square, for example, the linkage coupling the actuator and the ram is Y-shaped, with the two short V-shaped legs being assigned to the ram and the long leg to a first lever arm of the actuation . The legs, which are aligned in a V-shape with respect to one another, are associated with their free ends on one side of the press ram. Overall, the linkage runs parallel to the associated side wall of the refuse bin.

Preferably, the V-shaped limbs have bearing means at their free ends and in the coupling area with the long limbs of the linkage, which are guided in linear guide slots of the associated side wall and in the coupling area of the long limb with the lever arm of the actuator, a guide slot guided in an arc storage facilities are available. The bearing means designed as sliding or roller bearing means, for example bearing rollers or bearing rollers guided in the guide slots, reduce the force required for the displacement of the press ram and bring about a relatively trouble-free movement sequence. Furthermore, the pivoting movement of the actuation or of the lever arm coupled to it is converted into a linear lifting movement of the press ram in a defined position.

The bearing means assigned to the V-shaped legs are expediently connected to holding brackets which hold the press ram on their free end faces pointing in the direction of the container. The immersion depth of the press ram in the container in the compacted position can be determined by the dimensioning of the holding brackets, in particular the dimensioning of the holding leg holding the press ram.

In order to enable a uniform transmission of force from the actuator to the ram, each of the side walls is assigned a linkage and the lever arms arranged on both sides are coupled by means of a connecting element of the actuator, with the first lever arm on a pivot bearing merging into a second lever arm and the free one End of the second lever arm supports the connecting element of the actuation. To connect the actuator to the closure means, the press ram is preferably connected to the closure means via a connecting bracket. There is therefore a forced connection between the press ram and the closure means and thus also between the actuator and the closure means, which enables the waste bin to be operated relatively safely for a user.

To raise and lower the container when the actuator is acted upon, at least one two-armed lever arrangement is effective between the bottom of the container and the actuator, one arm of which is assigned to the first lever arm of the actuator and the other arm of which is assigned to a bolt mounted in a guide eye, which is assigned to the bottom of the container is assigned.

It goes without saying that the features mentioned above and still to be explained below can be used not only in the combination specified in each case, but also in other combinations. The scope of the invention is defined only by the claims.

The invention is explained in more detail below using an exemplary embodiment with reference to the associated drawing.

The waste bin 1 has a cover 2 and peripheral cladding elements 3, with a deposit opening 4 adjacent to the cover 2 being provided in a front panel 12, and two slot-shaped openings 5 running parallel and spaced apart from one another in the bottom area, through which an actuator 6 with a in front of the front panel 12 extending connecting element 7 protrudes. The connecting element 7 can, for example, with a foot user are operated. The insertion opening 4 is assigned a closure means 8 which comprises slats 9 coupled to one another in the manner of a roller blind and which is connected to the actuator 6 in order to release or close the insertion opening 4 .

Below the square, for example rectangular or square cover 2 extend two parallel side walls 10 which are connected to one another in the area of the cover 2 via two cross braces 11 and on the opposite side of the cover 2 to a base plate 13 . Between the two side walls 10 there is a removable container 14, for example a waste bin, with a square cross-section. A press ram 15 is mounted parallel to the cover 2 between the two side walls 10 and is connected to the actuator 6 via lateral rods 16 and to the closure means 8 via connecting brackets 17 on the front. The ram 15 can be moved into a filling position and a compaction position, in which case both the insertion opening 4 and an opening 18 on the top side of the container 14 are exposed in the filling position, and in the compaction position the ram 15 can be opened with an insertion opening 4 closed by the closure means 8 in immerses the container 14 in order to compress the waste present therein, which is paper that is relatively easy to compact, for example paper towels, or household plastic packaging, from a certain filling level or reliably press it into the container 14. If the container 14 is made of cardboard or has an insert made of cardboard or paper, the container 14 or the insert can be removed together with the compacted waste, preferably the paper, and recycled.

So that the ram 15 can dip into the container 14 and reliable displacement is ensured, two spaced-apart brackets 19 are arranged on each side running parallel to the side walls 10, the first bracket arm 20 of which extends parallel to the side wall 10, starting from the ram 15 and its length essentially the immersion depth of the ram 15 in the container 14 is determined, and the second bracket arm 21 extends parallel to the ram 15 to the adjacent side wall 10 and is connected to the linkage 16.

The linkage 16 is essentially Y-shaped, with the two short legs 22 running towards one another in a V-shape being connected to roller-like bearing means 23, for example, which extend through guide slots 24 in the associated side wall 10 and are connected to the second bracket arms 21 of the bracket 19 are. The guide slots 24 are aligned in a straight line and at right angles to the ram 15 . The long leg 22 of the linkage 16 is connected via a joint 25 to the short legs 22 running in a V-shape towards one another.

A first lever arm 26 of a two-armed lever 27 of the actuator 6 is connected to the long leg 22 of the linkage 16 via a further joint 25 . A bearing means 23 is present on the joint 25, which is guided in a curved guide slot 24 in the associated side wall 10, in which a pivot bearing 28 of the lever 27 is also formed, the second lever arm 29 of which extends through the associated clearance 5 in the front panel 12 extends and the connecting element 7 supports. The pivoting movement of the connecting element 7 of the actuator 6 is converted into a straight-line movement of the press ram 15 by the joints 25 and the guide slots 24 .

In order to achieve further compaction of the waste in the container 14 with a defined lifting height of the press ram 15, a two-armed lever arrangement 31 is effective between a base 30 of the container 14 and the actuator 6, one arm 32 of which is connected to the first lever arm 26 of the actuator 6 and the other arm 33 of which is associated with a bolt 35 mounted in a guide eye 34, the bolt 35 extending from the bottom 30 of the container 14.

In the compression position, in which the ram 15 is in the raised means of the lever assembly 31 container 14 and the insertion opening 4 in the Front panel 12 is closed by means of the closure means 8, the connecting element 7 of the actuator 6 is raised to the maximum. This compacted position can be assumed with an unloaded connecting element 7, for example due to the weight of the ram 15 and/or acting tension or compression springs and/or by lifting the connecting element with a foot of the user. To insert waste into the bin 14, the user slings the link 6 of the actuator 6 in a direction opposite to the lid 2, lowering the bin 14 towards the bottom plate 13 and pressing the ram 15 to release the opening 18 of the bin 14 and the closure means 8 are shifted to release the insertion opening 4 in the filling position. Here, the slats 9 of the closure means 8 mounted on the opposite side walls 10 slide from the position running parallel to the front panel 12 into a position which is at least partially aligned parallel to the press ram 15 . The user can throw waste into the container 14 in this filling position. He then releases the actuator 6 or its connecting element 7 and the ram 15 slides due to its weight, optionally with the assistance of spring force, into the compacted position in which it is located in the container 14 . At the same time, the container 16 is raised by means of the lever arrangements 31 and the closure means 8 closes the insertion opening 4.

Of course, the waste in the container is compacted after a certain level has been reached. In that case, the ram 15 causes waste to be transported into the container 14 .

The waste collector is described here in connection with a container with a square cross section. Of course, any other desired cross-section can also be realized with appropriate adjustment of the ram 15 .

To provide an electromechanical anti-trap device, an electronic controller 36 is provided, which includes a computer module 37 and for Supply of electrical energy with a power supply or a battery assembly 38 is connected. Two limit switches 39 are connected to the controller 36 and detect an open and a closed limit position of the intermediary 8 . Furthermore, two preferably electromechanical actuators 40, 41 are connected to the controller 36, with the first actuator 40 being assigned to the long leg 22 of the linkage 16 and the second actuator 41 preventing displacement of the press ram 15.

In an initial position, the insertion opening 4 is covered by the closure means 8 and the associated limit switch 38 is actuated. Furthermore, the controller 36 acts on the actuator 40 assigned to the long leg 22 of the linkage 16. When the actuator 6 is acted upon in a direction opposite to the cover 2, the container 14 moves in the direction of the base plate

13 lowered and the ram 15 to release the opening 18 of the container

14 and the closure means 8 are shifted to the filling position to release the insertion opening 4, the movement of the closure means 8 is detected by the associated lower limit switch 39 and the first actuator 40 is deactivated to release the movement of the linkage 16. If the upper limit switch 39 detects the closure means 8, then the insertion opening 4 is released and the ram 15 is in the filling position. The ram 15 is secured by the second actuator 41 in this filling position. When the actuator 6 is released/released, the locking means 8 closes the insertion opening and actuates the lower limit switch 39, with a corresponding signal being applied to the controller 36 to cancel the locking of the press ram 15 with the second actuator 41 and the press ram 15 slides into its compaction position. in which the locking effected by the first actuator 40 closes. If there is no voltage, then the two actuators 40, 41 are locked and actuation is prevented.

To provide mechanical anti-trap protection, a coupler 42 is mounted in a pivot bearing 43 in the side wall 10, one leg 44 of which interacts with one end of the closure means 8 and the other leg 45 of which has an angled guide groove 46 with a locking section 47. into which an actuating cam 48 extending from one of the short legs 22 of the linkage 16 engages in a sliding manner, with the actuating cam 48 protruding through a slot 49 in the side wall 10 .

In an initial position, the insertion opening 4 is covered by the closure means 8 and the actuating cam 48 lies in the locking section 47 of the guide groove 46, so that manual lifting of the closure means 8 is prevented. When the actuator 6 is pressed down, the actuating cam 48 slides in the linear guide groove 46 and the ram 15 is increasingly moved upwards out of the container 14 until at the end of the guide groove 46 a pivoting movement of the coupler 42 begins and also the closure means 8 to release the insertion opening 4 is relocated. When the actuator 6 is released, the coupler 42 first moves to close the insertion opening 4 with the closure means 8 and then the press plunger 15 moves into its compacted position as already described.
