Definitions
- the present invention relates to a device for the automatic compacting of empty containers, for example disposable bottles and cans of metal, plastic, glass or other material suitable for such containers .
- the device is particularly suitable as part of a reverse vending machine which receives used beverage packaging.
- packaging items are compacted individually, without the packaging item being divided into several pieces, which simplifies the sorting of the different types of material in a subsequent processing.
- compacting of glass is normally done by smashing, so that the glass is divided into many smaller fragments.
- one and the same compactor should allow compacting of several types of packaging, as for example plastic bottles, steel cans, aluminium cans and glass bottles of volumes from 150 millilitres to 3 litres, in order to minimize the number of modules in a reverse vending machine such as described above.
- So-called belt compactors which are based on endless belts produced of a flexible material are often provided with a number of studs mounted on the belts for puncturing and gripping packaging.
- a device of this kind as it is described in US patent 5,522,311, is subject to great wear.
- the studs which are formed of a hard material, e.g. steel, are mounted in the flexible belt which is produced from a soft material, e.g. rubber. The rubber is worn by both friction and forces acting between the containers and the belt and forces between the studs and the rubber of the belt.
- So-called belt compactors utilize endless belts consisting of rigid plates hinged together, such as described in WO 00/40397. This type of compactor is formed of a great number of parts which move individually relative to each other. Each of the so-called hinges is subjected to wear as packaging is being compacted.
- Belt compactors are not suitable for compacting/breaking glass because the pressure of the belt is normally distributed across too large an area for the glass to be broken.
- the object of the invention is to provide a compactor which is capable of quick, simple and efficient compacting of empty containers, so that costs related to handling, storing and transport are reduced, while at the same time the containers are destroyed in such a way that recognizable properties, e.g. shape, are changed so much that repeated insertion into a reverse vending machine with subsequent additional payment of return value will not be possible.
- a compactor according to the invention is provided with two sets of jaws, so-called jaw sets, in which each jaw is formed as a rod, and in which the underside of the rod, which comes to rest on the containers, is formed with teeth.
- the jaws are supported on two co-rotating eccentric shafts that make the jaws move in an eccentric parallel motion during operation.
- the two jaw sets are formed in such a way that each alternate jaw, as seen transversally to the moving direction, belongs to a first jaw set, whereas the other jaws belong to the second jaw set.
- the jaw sets are supported on common shafts, but are 180 degrees offset relative to the centres of rotation of the shafts.
- the jaw sets are placed at an angle above a conveyor belt, so that the distance between the jaw sets and the conveyor belt is the smallest at the outlet end portion of the belt.
- the compactor may be provided with partition walls placed between two jaws, thus forming two or more parallel channels through the compactor.
- the teeth of the jaws may be formed differently in the channels, as each tooth of one set of teeth, individually or in groups, may be formed in such a way that the tooth/teeth perform a particular task, such as gripping, puncturing, hammering or crushing. In the following an area of such a particular task is called a segment. Segments of a jaw may also be without teeth if this is desirable, e.g. in order to achieve flat-pressing.
- Each jaw is formed individually to exert optimum compacting of a type of packaging, e.g. metal, plastic or glass.
- the teeth of at least a portion of the set of teeth are formed so that they have at least two peaks beside each other relative to the longitudinal direction of the jaws. Thereby the teeth grip the bottle at the same time as the bottle is being punctured.
- the conveyor belt comprising an endless band and necessary driving elements carries containers in below the jaw sets.
- a support plate which acts as a holding-up means for the jaws during compacting. With respect to angle and distance relative to the conveyor belt segments of each jaw may be so formed that method and degree of compacting may be selected for each channel.
- the conveyor belt is hinged to the structure of the compactor.
- a spring mechanism e.g. in the form of a gas spring, is arranged between the discharge end portion of the conveyor and the structure of the compactor. The spring mechanism is arranged to limit the maximum force that may be applied to a container between the band and the jaws.
- the spring device will yield, so that the object can be carried through the compactor without damaging the components thereof. If the object is too large to be carried through the compactor, the belt conveyor will be subjected to a force which causes the release of a switch and the compactor is stopped. The spring mechanism may then be released and the belt conveyor lowered, so that the object may be removed.
- Fig. 1 shows the compactor in a side view, seen from the gas spring side
- Fig. 2 shows the compactor in a side view, seen from the feeding side
- Fig. 3 shows the compactor, partly in a sectional side view, seen from the driving side
- Fig. 4 shows the jaw operation of the compactor, seen from above;
- Fig. 5 shows, in perspective, a jaw with teeth for the compacting of plastic containers
- Fig. 6 shows the compactor in a side view, seen from the gas spring side in a state of operation, in which the conveyor belt is in a lower position.
- the reference numeral 1 identifies a compactor comprising a structure 10, a conveyor belt 20 and a jaw device 30.
- the structure 10 is provided with sidewalls 12, 12' arranged to absorb the forces from the jaw device 30 and form a securing point for a driving motor 22 and pivoting point 23 of the conveyor belt 20 and rotational point 15 for a release arm 14.
- a gas spring 16 is connected to the release arm 14. The operation of the release arm 14 will be described below.
- the conveyor belt 20 comprises a frame structure 24 comprising a support plate 26, a belt 28 and a turning roller 29.
- the jaw device 30 is placed above the conveyor belt 20, and is sloping down towards the turning roller 29.
- the jaw device 30 is connected to the sidewalls 12 by means of bolts 31 and is thereby arranged to allow easy dismantling for maintenance or replacement.
- Two sets of jaws 32 are connected to a mounting plate 34 each.
- Tow mounting plates 34, 34' and a number of jaws thus form a jaw set 36, see Fig. 4.
- Tow jaw sets 36a and 36b are rotationally supported on two common eccentric shafts 38, 38', so that the supports of the jaw sets are rotated through 180 degrees relative to one another relative to the centre of rotation of the eccentric shafts 38, 38'.
- the eccentric shafts 38, 38' are rotatably secured to the sidewalls 12, 12' and driven by an electric motor 40 through a belt transmission 42.
- each alternate jaw 32 belongs to the jaw set 36a or 36b, respectively.
- the jaw sets 36a and 36b are moved in eccentric parallel paths, while being offset at the same time, so that when one jaw set, for example 36a, is in its upper position, the jaw set 36b is in its lowermost position.
- One or more partition plates 44 divides the active area of the compactor 1 into two or more channels .
- the jaws 32 are provided with teeth 46 which are arranged to grip and possibly also puncture the containers .
- containers 5 are placed on the entrance side of the conveyor belt 28 above the driving motor 22. If the compactor is provided with one or more partition plates 44, the channel adapted for the packaging in question is selected.
- the first jaw set 36a and the second jaw set 36b rotate at the same frequency and 180 degrees out of phase.
- the container 5 touches one jaw set 38a which is moving in a direction towards the belt 28, one or more teeth 46 of one or more jaws 32 will grip the container 5 and possibly puncture it.
- the jaw sets 38a, 38b and the conveyor belt 28 together will pull the container 5 further into the compacting area between the conveyor belt 28 and the jaw device 30.
- the jaw sets 38a and 38b are moving 180 degrees out of phase, at least one of the jaw sets 38a, 38b will always be in contact with the container 5.
- the eccentric and parallel movements of the jaw sets 38a, 38b will cause the teeth 46 of the jaw 32 to be forced into the container 5 before the container 5 is pulled forward.
- the teeth 46 of the first jaw set 36a are withdrawn from the container 5 while the teeth 46 of the second jaw set 36b are simultaneously forced down into the container 5.
- the first jaw set 36a then returns to its initial position by a 360 degrees' rotation of the shafts 38, and the sequence is repeated. This motion results in a continuous compacting based on a series of partial compactings performed by the jaw sets 36a and 36b.
- the gas spring 16 is arranged to yield by way of the release arm 14 which is supported on the rotational point 15 and connected to the turning roller portion of the conveyor belt 28, so that the conveyor belt pivots on the pivotal suspension 23, whereby the container 5 may pass through the compactor 1 without the conveyor belt 28 being overloaded, see Fig. 6.
- the compacting of plastic bottles with screwed-on caps requires puncturing of the bottle before compacting. Without puncturing, the bottle will return to its original shape after having been compacted, because of the air pressure formed inside the bottle.
- the jaws 32 which are arranged to compact plastic bottles, are provided with teeth 46 formed by two peaks beside each other relative to the longitudinal direction of the jaw 32.
- Plastic bottles with caps may contain liquid, and this liquid may cause problems for the compactor 1 and the collecting packaging. Normally the amount of liquid per bottle will be limited because the container is normally weighed in a device located upstream relative to the compactor 1. Containers 5 with too much liquid are returned to the user. It will still be possible for containers containing liquid to be admitted into the compactor 1.
- any configuration of the jaws is possible as long as the receiving area between the jaw sets 36a, 36b and the conveyor belt 20 is essentially cuneiform, and the teeth 46 of the jaws 32 perform the task intended relative to the type of material to be processed.
