Description
- The invention relates to a compressing device for compressing waste to be collected in a waste container.
- Known from the Netherlands patent application no. 1005958 is a waste container which can be sunk into the ground in a concrete holder and which is provided with openable bottom parts and with a cover part on which a column is placed with an inlet channel debouching above an inlet opening in the cover part. Such a waste container is used for collecting domestic refuse tendered in plastic sacks, but also for collecting for instance glass. The container is emptied in due time using a hoisting device intended for this purpose, wherein the container is successively lifted out of the concrete holder and placed above the loading platform of a truck and the bottom is opened by activating the operating means.
- It is a drawback of known waste containers that the deposited waste has a low density since the plastic sacks and the waste collected therein (for instance packaging material) contain a large amount of air, as a result of which the waste containers must be emptied relatively frequently. The emptying of waste containers is labour-intensive, and therefore expensive.
- It is an object of the invention to provide a compressing device, using which waste is compressed to a substantial degree so that the volume of a waste container can be optimally utilized, and a waste container with compressed waste requires less frequent emptying than a container with waste which is not compressed.
- It is a further object to provide a compressing device which can be applied in combination with per se known waste containers.
- Another object is to provide a compressing device which is robust and corrosion-free, and thereby requires little maintenance.
- These objectives are achieved, and other advantages gained, with a compressing device for compressing waste to be collected in a waste container, which according to the invention comprises a frame which is placeable on an inlet opening in the upper side of a waste container and in which at least one first roller provided with a drive and rotatable in a first direction and a compressing member are mounted at a determined mutual distance for feeding in waste to be compressed into the waste container between this roller and the compressing member.
- The compressing of waste by feeding it into a waste container between a roller and a compressing member provides the advantage that no separate compressing operation is required. Because a frame with a roller and a compressing member can be placed outside a waste container, it is not necessary to take any volume from this container for the compressing device, and the compressing device according to the invention moreover provides the advantage that it can be placed on waste containers which are already in use.
- In an embodiment of a compressing device according to the invention, the compressing member comprises a second roller parallel to the first roller and rotatable in a second direction opposite to the first direction.
- In this latter embodiment at least one of the rollers is for instance mounted in displaceable bearings confined under a spring force in a manner such that the mutual distance between the rollers is variable.
- This embodiment provides the advantage that non-compressible constituents, inasmuch as the dimensions thereof remain within determined limits, can pass through the rollers, wherein these are pressed apart.
- In yet another embodiment of a compressing device according to the invention, the compressing member comprises a flat plate running obliquely downward in the operating position toward the first roller and parallel to this first roller, which plate is preferably suspended on its top side for pivoting counter to a spring force.
- The spring force is produced for instance by a gas spring directed toward the first roller.
- In an embodiment the drive is an external drive, for instance a motor reductor provided with chain wheels.
- In a preferred embodiment the drive is provided in the interior of the first roller.
- An internal drive is for instance provided by a so-called drum motor.
- The drive comprises for instance a mains motor.
- In a preferred embodiment the drive comprises a low-voltage direct current motor.
- A suitably chosen low-voltage direct current motor, for instance a 12-volt or 24-volt motor, provides the advantage that the power supply required therefor is already available for the required read electronics in waste containers which can be placed underground and which are only accessible after recording of the tendered waste by means of electronic reading of a chipcard intended for this purpose.
- In an advantageous embodiment of a compressing device according to the invention, at least the roller provided with a drive is provided with a releasable sleeve, the outer surface of which comprises an anti-slip material.
- With such a roller the anti-slip material prevents waste slipping on the surface of the roller. The fact that the outer sleeve is releasable provides a cost advantage, particularly in the case of driving by a drum motor, in that only the outer sleeve, and not the entire roller, need be replaced in the case of damage or wear of the surface of the roller.
- In yet another embodiment at least the first roller is provided with longitudinal ribs extending in longitudinal direction on the outer surface for easy infeed of waste for compressing.
- In another embodiment the compressing device is provided with an infeed funnel debouching above and between the first roller and the compressing member.
- In a further embodiment the compressing device is provided in a column which is placeable on a cover part of a waste container and which is provided with an inlet channel debouching above an inlet opening in this cover part.
- In a practically advantageous embodiment the compressing device according to the invention is provided with detecting and signal processing means for detecting waste to be compressed which is fed between the roller and the compressing member.
- This latter embodiment is particularly suitable for use in combination with a waste container wherein information concerning the amount of waste to be fed in must be recorded in combination with an identification of the user, for instance in a situation where costs for the use of the waste container are charged to the user.
