Description

The invention relates to a device for sorting and controlled conveyance of material groups to sort objects for recycling and waste disposal.

From the prior art, for example from the GB 2269774A and the FR 2800304 A1 Commercially available sorting devices are known which can sometimes sort fully automatically waste products according to certain properties, in particular their constituents and recyclables. In order to be able to achieve particularly high levels of purity during sorting, it may be necessary to sort by hand. Especially with high throughput rates, the sorting for recyclables is sometimes very difficult. There are sorting aids from the household and hobby sector, for example, according to the US 5,117,982 A which allow individual beds of fractions but can not meet the required throughput rates, for example in a sorting plant.

The object of the invention is to provide a device for sorting and controlled conveyors, with which a faster and more accurate sorting can be achieved.

The object is achieved, starting from a device of the type mentioned, by the features of claim 1.

The measures mentioned in the dependent claims advantageous embodiments and modifications of the invention are possible.

Accordingly, a device for sorting and controlled conveyance of by value groups to sorting objects a Sortiertribüne and at least one transport device, wherein the transport device has at least one partition, with which the transport path can be divided into at least two channels and at least one loading as a mechanical obstacle in transporting the objects from the transport path to a downstream fall distance.

The objects are to be sorted according to material groups. On the one hand, this means, for example, that it is sorted according to whether the corresponding objects made of PET (polyethylene terephthalate) consist of PEHD (hard polyethylene) or of other plastics. It can also or additionally be sorted by color, for example, whether transparent, light PET bottles or dark colored PET bottles, white, green, etc. are present.

Each of these recyclable groups can be assigned to a channel. The presorting or actual sorting is automated. For this purpose, a wide variety of optical methods, X-ray methods or mechanical methods can be used. Corresponding sorting components are, for example, ballistic separators, sieve drums; However, as described, more specific determination methods such as optical methods or X-ray analyzes are basically used.

In the present case, these are in particular sorting systems for light packaging, for example the sorting of plastic waste and lightweight packaging, films, bottles, smaller containers, etc., which are recyclable. Households collect such packaging waste mostly in the yellow bag or the so-called "RaWEG bag" or any containers that are connected to the dual system. With the help of, for example, a ballistic separator, a mechanical pre-sorting into light and rolling heavy parts takes place first. Subsequently, an optical sorting can separate PET bottles and PET hollow bodies. Separation methods such as the sink-float separation can also be used. in which objects can be separated according to their specific weight. Such separation processes achieve purities of well over 90 percent.

In many cases, a manual sorting by persons takes place in order to achieve purity levels of 98 percent and more.

The sorted or pre-sorted objects are transported, for example, with conveyor belts. Although the re-sorting only makes a small contribution to the sorting on a percentage basis due to the already achieved high purity grades, this is sometimes very difficult, especially at high throughput rates.

The corresponding person is forced to concentrate on different channels, with the result that the throughput must either be reduced by reducing the conveying speed of the presorted objects or it has to be accepted that increased sorting errors occur at the expense of a lower degree of purity can.

The sorting is particularly difficult, since the same amount of objects to be sorted is not always generated for the individual material groups. For example, a large amount of waste to be sorted may contain PET bottles, but only a small proportion of PEHD parts. Especially if objects are presorted into the wrong resource group simultaneously in several channels, the simultaneous resorting or re-sorting of these objects is correspondingly more difficult.

In order to enable high levels of purity nevertheless, the stock of sorting personnel could in principle be increased, which, however, leads to significantly higher costs and is therefore undesirable. In principle, it is also conceivable to reduce the speed of the conveyor belt, but at the same time leads to a reduction in throughput, especially since the entire sorting system regularly has to be throttled in its speed, so that a regular operation and a regular functioning continue to be guaranteed.

For this purpose, at least one loading is arranged as a mechanical obstacle when conveying the objects from the transport path to the drop route between the transport path on which the presorted objects are brought in the direction of sorting turrets from which an operator takes over the re-sorting. The drawer can be advantageously used so that at the point where the operator takes over the re-sorting by hand, the objects are accumulated, so that the operator gains time to carry out a subsequent sorting conscientious.

In the device according to the invention, it is particularly advantageous that the speed with which the transport device leading to the sorting platform does not change, in particular does not have to be slowed down. In addition, operating personnel can be saved, since, as already shown, by the present device provides a considerable relief in the after-sorting and time advantages. The transport device may in principle comprise a plurality of individual transport devices, such as a plurality of conveyor belts; but it may also be a single transport device, for example, a single conveyor belt, which is divisible by partitions in several sub-areas, so-called channels. Each channel can accordingly be assigned a resource group.

If only a single transport device is used, which is divided by at least one partition into individual channels, this has the fundamental advantage that the removal of the presorted waste after a presorting is uniform and not the removal of a certain presorted recyclable group is faster than the other, what in turn could lead to damming up the refuse. The drawer can in principle be arranged so that it only serves as a Obstacle and not as a complete blockade, which means that the objects can initially accumulate, but from a certain amount forwarded.

Behind the transport path of the transport device is immediately downstream of the charging, then in turn a drop route.

For example, as soon as a certain number of objects are dammed up, they can overcome the artery and reach the drop route. In particular, this makes it possible to accomplish a more precise subsequent sorting.

Just when a large number of objects in a channel is transported in the direction of Sortiertribunee, while in a different channel only very few objects are present, it is conceivable, for example, in this channel, which includes only a few objects for a certain Time with the help of the ark to accumulate the objects, because in a relatively short time in the other channel that delivers more objects, a sorting must be done. If, in this channel, which includes many objects, namely not sorted in time, so get some of these objects in a short time on the case route and can not be resorted, since they are no longer easily accessible by the operator. The fact that, as it were, one of the channels in which a sort currently does not appear to be particularly urgent is "neglected" for a short time, the more urgent sorting in a channel can, as it were, be "preferred".

In principle, the device for sorting and controlled conveyance according to the invention can be used for all conceivable sorting operations, for example also for metal sorting.

It is particularly advantageous if the drawer is adjusted with respect to its angle to the transport path of the transport device so that it has a different mechanical resistance in conveyed objects during transport opposes. In particular, the tray can also be designed as a chute, which allows a different speed depending on the angle of inclination.

Behind the drawer, a passage opening may be present, so that the objects can finally reach the drop route via the passage opening. The passage opening is then bounded to one side by the tray, to another side by a boundary wall. The operator thereby has more time to perform the re-sorting operation, while if too many objects accumulate in this area of the tray, the objects can still pass through the opening to the drop zone, thus avoiding clogging.

Conceivable, inter alia, two possible embodiments:

On the one hand, an embodiment in which the drawer, which adjoins the transport path via the transport device, is inclined upward, that is to say on the side on which the objects are conveyed, the drawer closes an angle of less than 180 ° with the conveyor belt (180 degrees). In this case, the loading itself forms a mechanical obstacle for the transported objects by their angle of attack, since they have to overcome this mechanical obstacle (against gravity) on further transport.

Preferably, however, the tray is designed as a chute, that is, it is inclined with respect to the transport path that on the side on which the objects are transported, the loading with the conveyor belt at an angle greater than 180 ° or includes on the side facing away from it, usually below the conveyor belt, an angle smaller 180 ° includes. The mechanical resistance is then formed on the one hand by the frictional resistance itself, which has the tray opposite the transported objects, on the other hand by the size of the opening, which is bounded on one side by the tray and forms the passage to the drop distance.

If, for example, this opening is barely larger than the average size of an object, then damming will easily occur, especially as objects tend to become wedged easily in the opening. Consequently, if the drawer is designed as a chute, the mechanical obstacle is mainly composed of the friction that the chute has with respect to the objects, the inclination angle of the chute and the size of the passage opening, which determines how quickly a jam can occur ,

Basically, the question of whether a jam comes about, also influenced by how many objects at once reach the passage opening. If the passage opening, for example, slightly larger than the transported objects, then no jam will arise when objects pass successively to the passage opening without z. B. to stand diagonally and to wedge. However, the conveyed objects are usually present on the conveyor belt as accumulation and as a batch. In addition, individual objects that are separate from such clusters can usually be detected easily and quickly. The subsequent sorting can thus be substantially facilitated.

In a particularly preferred embodiment of the invention, the tray is rotatably mounted and adjustable in terms of their angle to the transport path and / or the boundary wall of the drop distance. By this measure, the mechanical Widerstrand or the mechanical obstacle can be adjusted when moving the objects. Optionally, the mechanical obstacle can also be set so small that the transported objects are transported practically without noticeable resistance on. If the drawer is designed, for example, as a chute, the chute can in principle also be set almost vertically downwards, so that the objects reach the drop path practically directly.

Furthermore, the passage opening can be increased or decreased by tilting the tray. The larger the passage opening, the easier the objects can be fall through. If the load z. B. tilted away down (slide), is an enlargement of the passage regularly associated with a steeper course of the slide. However, the chute can also be adjusted so that the friction causes the objects to be braked practically completely on the chute after the transport device. Moreover, the chute itself does not include a machine conveyor such as a conveyor belt. Depending on the friction or mechanical resistance, in principle, the conveyed objects, which reach the drawer after the transport device, can be braked so that they remain lying on the drawer.

This adjustment, which allows a rotatable storage of the load, offers, among other things, the advantage that it can be set individually by the operator, so adapted to how much by sorting waste to be sorted to the device.

In one embodiment of the invention, the operator, who is to sort the refuse, stands on a sorting platform, which is designed to allow access to the channels. The Sortiertribüne is thus arranged so that the operator is advantageously in the operating range of the drawer. As Sortiertribüne may be any space or any device for receiving an operator in the context of the invention, which allows this access to the drawer or the shop for sorting.

Further, the sorting turret may include an operating device for adjusting the angle and / or moving the tray. The operator can thus regulate the mechanical resistance directly from their working position on the sorting platform.

In general, the garbage mountain to be sorted comprises an irregular or uneven distribution according to individual recycling groups. After presorting, the presorted objects, which already have individual channels and are thus assigned to individual groups of recyclables, in the direction of the Sortiertribüne. It is usually completely left to chance, how many objects in a particular channel at a certain time arrive at the Sortiertribüne. Consequently, it is particularly advantageous to provide not only one tray for adjusting the mechanical obstacle, but several.

It is particularly preferable to assign a single load to each individual channel. This measure can take into account how many objects are currently arriving in a particular channel. As already described, a situation is conceivable in which a relatively large number of objects arrive at the sorting platform on one channel, while other channels are largely empty. Due to the adjustability of the load is then allowed that exactly the channels that just lead few objects, are initially dammed up, in which the mechanical resistance is increased by adjusting the load. In this time, the operator can then, where arrive in a short time many objects to be sorted, perform the re-sorting, without fear that in other channels that lead little objects, they simply go unseen on the case route and thus no longer resorted can be.

Correspondingly advantageous can also be benefited by this embodiment of the invention that there is an uneven waste distribution over the transport path away. If, in all channels, the number of transported objects is low anyway, it may be sufficient to set all the stores to a low mechanical resistance, since the operator can then relatively easily resort to sorting. If about the same number of objects arrive at the sorting platform via the individual channels, then the mechanical resistance can be increased by adjusting the loading, so that the operator has more time per channel for sorting. However, if the number of objects per channel is about the same, which per unit of time at the Sortiertribüne commented, so it is usually advisable Adjust the load in a similar way so that the mechanical resistance is about the same for each channel.

Thus, the pre-sorting, which is improved by the re-sorting once again in terms of their purity, is maintained, the fall distance is also advantageously divided by at least one shut-off device in partial fall distances, which are each associated with a loading and / or a channel.

If the objects fall after the sorting over the drop distance into a container, it is conceivable either to provide a separate container for each channel or each recyclable group or to postpone a container which is divided into sub-containers, so that the finished sorted objects according to material groups / channels ordered in the individual sub-containers can fall separately.

It is also conceivable in principle that instead of a container, a further transport device is behind the drop route. It is also conceivable that some objects fall into a container immediately after the fall distance, while others must be transported further. This may be desirable, for example, when various types of sorts are performed in stages. For example, it is conceivable first to sort objects by size and then to perform a sorting according to material properties or according to material composition. It is also conceivable, for. B. in a first step to sort objects according to their specific density and, for example, then by color. For the objects, then z. B. no longer need to be sorted due to their specific density, since the assignment to the appropriate resource group is sufficient, then can be collected by traversing fall distance in a container, while the other, to be sorted out in more detail to be sorted objects, z. B. to the next sorter.

Such a further transport device, which the Downstream case, for example, can be designed as well as the transport device, which leads to Sortiertribüne. It is conceivable, for example, a training as a conveyor belt. A conveyor belt is characterized in particular by the fact that a wide variety of objects of different weights and sizes can be transported largely independently of these properties.

In addition, in a development of the invention, the transport device is designed such that the channels are essentially arranged next to one another in each case. Through this training, several advantageous properties can be used. On the one hand, this measure represents a relief and a particularly clear situation for the operator who is to sort the pre-sorted waste again. In this embodiment, the sorting and conveying device is to a certain extent designed as a "front sorting station", that is to say the objects to be sorted run directly towards the operator or sorting platform so that during regular operation the operator looks directly at the incoming and subsequently sorted objects. The operator can thus also immediately estimate where or in which area, if appropriate, a drawer should be changed in terms of its mechanical resistance and react immediately to it, in which it makes this setting.

Depending on the design of the conveyor belt, the operator may also have enough time to make this adjustment, if they have appropriate insight on the conveyor belt or the transport path. The operator can thus gain at least a few seconds to make the adjustment. It is also conceivable, in principle, that such a setting of the tray takes place automatically, in which an optical monitoring device checks how many objects are currently lying on a corresponding strip or whether it is an accumulation of objects to be sorted. In addition, such a device still allows one Another advantage: the channels can in particular be arranged in parallel. Accordingly, it is possible to provide only a single conveyor belt for the transport path and this only separated by barriers into individual channels.

After the pre-sorting device, the pre-sorted objects can thus be transported away at the same speed, since it is only a single conveyor belt. At the same time, of course, costs can also be saved, since only a single conveyor belt is necessary.

In the case of sorting processes of this kind, items can sometimes also be placed under the objects which can not be assigned to any group of recyclables to which the sorting process currently in existence shuts off. For example, it may be that glass bottles or metal parts are not completely sorted out after pre-sorting. These objects can not be assigned to another channel during the re-sorting process. They must therefore be sorted out. Therefore, in a development of the invention directly adjacent to the tribune at least one receptacle for receiving objects that are assigned to any of the recycling groups, arranged. The operator can then sort out, for example by hand, the corresponding objects.

It is also conceivable that such contaminants, which are attributable to any of the recyclable groups, is to turn off, can pass through laterally disposed discharge funnel into the container. It is advantageous that the appropriate operator who takes over the sorting does not have to lift the objects, but can only transport via the discharge hopper in the corresponding side container.

FIG. 3:

a schematic perspective view of the sorting device according to the FIGS. 1 and 2 according to the invention, as well

FIG. 4:

a schematic side view of a sorting device with a second conveyor belt according to the invention.

FIG. 1 shows a schematic side view of a sorting device 1 with a conveyor belt 2 in which objects 3 are conveyed in the conveying direction 4. The objects 3 have already been subjected to presorting. Immediately at the end of the conveyor belt 2 a loading 5 is provided (in total, several stores are available for all channels, cf. FIG. 2 ). The tray 5 can be tilted downwards, wherein the angle α between the conveying path of the conveyor belt 2 and the tray 5 on the side facing away from the objects is less than 180 ° (180 degrees). From the drawer, the objects can fall over a drop section 6 into a container 7. The drawer 5 can be actuated via an actuating lever 8, that is, with this, the tilting of the drawer can be adjusted or the drawer can be completely folded down. Immediately in front of the container a Sortiertribüne 9 is arranged, which can be an operator to perform the re-sorting in the area of the tray 5.

Moreover, the tray 5 is rotatably mounted about a pivot point A and further has a guide F in the present case is designed as a backdrop, so that the guide lever can be performed on a circular arc section.

FIG. 2 shows the same sorter from above. Shown is also the conveyor belt 2 in the plan view can be seen that the conveyor belt is separated via the partitions 10 into individual channels 11a, 11b, 11c and 11d. Channel 11a can for example be assigned to the recyclables group of dark PET bottles and PET hollow bodies, the channel 11b to transparent PET bottles or hollow bodies, the channel 11c to plastic bodies made of PEHD (hard polyethylene) and the channel 11d to other plastic parts. Furthermore, the conveying direction 4 is located. Overall, only one conveyor belt 2 is present, which, as already mentioned, is split up by partition walls into individual channels. The conveyor belt ends in the area of the store 5a, 5b, 5c, 5d. The store 5a - 5d are slightly folded down in the present case, that is called in the drawing of FIG. 2 viewed from the top view in the direction of the drawing plane. Shown after the store 5a - 5d, the passage openings 12a - 12d.

For Sortiertribüne 9 towards an opening 12 is visible immediately after the drawer. This is the passage opening, which finally leads to the drop section 6. Side of the Sortiertribüne 9 are waste containers 13a and 13b is conceivable, for example, that one of the waste container for glass waste, the other is intended for metal parts. It is also conceivable that in one embodiment of the invention laterally of the two outer store to the respective waste containers 13a and 13b out a kind of discharge hopper leads, so that contaminants can be easily passed through these discharge funnel into the waste container.

Channel 11a currently has a relatively large collection of objects 3a, channel 11b only a very small collection of objects 3b, while again channels 11c and 11d currently have no objects. In this case, the setting is the loading 5c and 5d temporarily without meaning. However, the tray 5b can be turned upward to form a slightly inclined chute and the passage opening 12b is small. The few objects 3b can therefore accumulate. The operator concentrates on channel 11a during this time, since there the object volume 3a is substantially higher than in the remaining channels 11b-11d.

FIG. 3 shows a schematic oblique view of the sorting device of the FIGS. 1 and 2 with an operator 14 on the Sortiertribüne 9. In particular, the sorting device 1 with the conveyor belt 2, the partitions 10 for the separation of the individual channels 11 (or a total of 11a to 11d). The operator 14 stands on a sorting platform 9 and sorts the individual objects within the individual channels 11a to 11d in order to obtain a particularly high degree of purity of the sorting waste. From the drawer 5, the sorted objects fall into the containers 7, whereby these can be assigned to the individual channels depending on the recycling groups. Side of the operator 14 and the Sortiertribüne 9 are the waste containers 13a and 13b can be disposed of in the contaminants. The Sortiertribüne 9 is, as can be seen here, arranged so that the conveyor belt 2 with its conveying direction 4 conveys the objects directly in the direction of the operator. Since this conveyor line ends almost immediately in front of the operator 14, a sorting with the aid of the store 5a-5d is easily possible.

FIG. 4 shows a similar sorting device 101 with a conveyor belt 102 for sorting objects 103, which are moved on the conveyor belt in the direction of the arrow 104. At the end of the conveying path, the objects 103 reach one of the stores 105 and fall over a drop section 106 onto another conveyor belt 107, this conveyor belt moves in the opposite direction 104 '(opposite in comparison to the conveying direction 104). The drawer 105 may also be connected via an actuating lever 108, which in FIG. 4 indicated only schematically is folded or positioned. Furthermore, the sorting turret 109 is also provided. The objects can in turn reach the drop distance via a passage opening 112. Also, the tray 105 can in turn be stored similarly, wherein the angle α on the side still facing away from the objects side is less than 180 °, the tray 105 is thus designed as a slide. The main difference to a device according to the FIGS. 1 to 3 consists in that instead of the container, a transport device 107 is provided, with which the re-sorted items can be transported on and then further processed, shredded or sorted again. Also conceivable is a combination of a device according to the FIGS. 1 and 4 so that the conveyor belt 107 does not extend over the entire width of the individual channels, for example, but only some of the channels finally land on the conveyor belt 107, while others in turn open directly into a container (see container 7).

In the embodiments according to Figure 1 to 4 the drawer 5 and 105 are each designed as a slide. It is also conceivable, however, that the tray 5 or 105 forms another mechanical obstacle such as a ramp. In this case of a "ramp", the angle α would be more than 180 ° and the angle β would be less than 180 °, where α + β = 360 °. If the drawer is designed as a chute, the mechanical obstacle arises essentially by the friction on the surface of the drawer, by its angle of inclination and by the size of the passage opening 12 or 112 (or more precisely: their size with respect to the objects).

Since the objects 3, 103 run directly onto an operator on the sorting platform 9, 109 via the conveyor belt 2, 102, the device for sorting and controlled conveyance of objects to be sorted according to material groups can also be referred to as a so-called "front sorting station".
