DE4210043A1 - Sorting device with cup or pocket sieve - Google Patents

Abstract

The invention concerns a sorting machine (1) which sorts, according to size, the components of a mixture such as rubbish, initially using a bucket-type sieve (2). The contents of the buckets (12) are subsequently blown out by a blower (8), thus separating out the lighter components of the mixture in the cups (12).

Description

The invention relates in particular to a sorting device for separating and sorting waste mixtures according to the Preamble of claim 1.

For sorting and separating mixtures with Components of different sizes and shapes using one Cup or pocket screens are already different Devices become known.

For example, it is on one of the Garbage sorting completely foreign area in the US-A 2 116 006 a device for sorting hops have been described. This device has a rotating Conveyor belt with a variety of pockets on top of that serves to separate the hop from the hop style. The from the  Bags of outstanding hop styles are made by one Brush sheared and flung away. The rest of the finer Hop parts fall when the tape is reversed, at which the Opening the pockets is swept down from the Bags in a designated container.

Furthermore, a sorting machine is known from EP 0 265 669 become known with a cup screen, the under is also suitable for sorting waste mixtures. This device has a cup provided Conveyor belt that is transverse to the conveying direction of the substance mixture to be introduced circulates. The one in the cups detained fine-grained goods are along a rising edge of the conveyor belt upwards transported, the coarser components of the Mixture due to the incline of the conveyor belt downwards slip and are constantly circulated. Over a upper deflection roller are connected to the conveyor belt Cup redirected and turned around for emptying. It is the conveyor belt transverse to its direction of rotation and along the original direction of transport of the goods to be sorted inclined that those not taken up by the cups coarser ingredients in this original Transport direction to be transported further.

With such a device can be very effective Components of a mixture are separated, which are differ due to their size and granularity. However, such a device cannot have any components separate the sorted goods, the comparable dimensions, however have a different weight. Such Separation would be extremely beneficial because of this  for example plastic parts of stone or metal goods could be separated.

Also the separation of film-like ones Plastic components compared to plastic containers the same size, such as cups or cans, can be used with a Device of the type mentioned can not be accomplished.

The object of the invention is therefore a To propose a sorting device that does not have a product to be sorted only because of its size or granularity, but also a sort by weight of the individual components of the goods to be sorted. These The task is started from a sorting machine initially designated type according to the invention by the characterizing features of claim 1 solved.

By the measures listed in the subclaims are advantageous further training and improvement in Main claim specified sorting device possible.

Accordingly, a sorting device with one on one Conveyor arranged cup or pocket sieve for sorting the goods to be sorted based on its different dimensions with a blow-out device further separation of the in the cups or bags provided sorted goods. This will make it  possible to remove heavy components of the goods to be sorted lighter components through the blow-out device be removed to separate.

It is particularly useful for the blow-out device between the filling and emptying zones of the cups to attach. This allows you to sort used cups are blown out without it additional containers for the sorted goods within the Blow-out device required.

An arrangement in the amount of is particularly advantageous Axis of rotation of the upper deflection roller of the cup screen. A such an arrangement has the consequence that the blow-out device blows into an almost right-angled cup and thus with a small expenditure of energy with comparatively low air pressure and correspondingly weak air flow the light components of what is in the cups Sort goods can be transported out of these.

Equipment of the Blow-out device with a blowpipe and one Collecting gutter recommended. This can, especially if that Blow pipe arranged parallel to a row of cups and with radial openings for generating the blow-out necessary air flow is provided, the blow-out device be arranged rigidly within the sorting machine. A such blow-out device worked along a straight line the entire width of the conveyor belt-type bucket screen, without an air nozzle or the like in connection with a Catcher along the cups back and forth is brought about.  

For removal of the collected in the gutter Sorting goods become the collecting channel opposite one horizontal plane inclined so that the goods to be sorted along this slope can slide down.

To improve the removal of the collected The gutter can be sorted with a special purpose certain transport device. Conceivable would be a drive that moves the gutter into a Vibration or shaking movement offset and thus one Start the gliding process as above or can support.

Another way of removing the sorted goods to accomplish from the gutter is through the Attach a conveyor belt to the bottom of the gutter given.

An embodiment of the invention is in the drawing shown and in the description below explained.

Show it

Fig. 1 shows a sorting machine according to the invention in perspective view;

Fig. 2 is a schematic cross section of a sorting machine according to the invention along the circumferential direction of the cup screen and

Fig. 3 shows an enlarged detail from FIG. 2 to better illustrate the blow-out device.

In Fig. 1, a sorting machine 1 is shown as the Applicant is known in principle from EP 0265669 B1. Reference is hereby expressly made to the content of this patent specification to describe the present invention.

This sorting machine 1 has a cup sieve 2 rotating around in the manner of a conveyor belt. Behind the Bechersiebwerk 2 there is a feed channel. 3 The cup screen is guided over a lower 4 and an upper 5 deflection roller. An extension of the axis of rotation 6 of the upper deflecting roller is an electric motor 7 for operating the cup screen 2 .

A blow-out device 8 is located at the axis of rotation 6 . This consists of a blow-out pipe 9 and a gutter 10, the entire device is mounted on a frame 11 .

The material to be sorted is fed to the sorting machine 1 via the feed trough 3 . The cup sieve 2 is designed such that rotating cups 12 are guided upwards as they move onto the upper deflecting roller 5 and at the same time are pivoted by approximately 90 ° into a horizontal position. At the level of the axis of rotation 6 of the upper deflecting roller 5 , the cups are thus in an ideal position in order to blow out light components of the items to be sorted from the horizontally inclined cups with very little energy expenditure. Compressed air is supplied via the blow-out pipe 9 and blown into the cup 12 . The direction of flow of the air is indicated by the arrows L emerging from the blow-out pipe 9 . The blown-out material is collected in the gutter 10 . Corresponding to the inclination of the gutter 10 , the collected material slides forward within the gutter and can be filled, for example, in a container, not shown.

In Fig. 2 is a schematic cross-section through such a machine during operation. The coarser sorting material 13 constantly rolls downward against the direction of rotation of the cup screen 2 due to its gravity. The in the beakers 12 finer sorting material 14 is guided upward and passes approximately at the height of the axis of rotation 6 of the upper guide roller 5, the blow-out. 8 The heavier sorting material 15 remaining in the cups 12 after blowing out is guided around the upper deflection roller 5 and then emptied out of the cups 12 for further processing. The blow-out device 8 is shown enlarged in the image section marked "Z" in FIG. 3.

In detail, the blow-out pipe 9 and a radially arranged blow-out opening 16 can be seen in FIG. 3. The compressed air supplied via the blow-out pipe 9 flows out of the blow-out opening 16 . The air flow outside the blow-out pipe 9 following the blow-out opening 16 is illustrated by arrows L. It encounters a cup 12 , which due to the above-mentioned circumstances is inclined almost horizontally, in the vicinity of the side wall 17 of the cup 12 which is at this inclination. At the bottom 18 of the cup, the air flow L is deflected, so that it finally leaves the bottom side wall 19 of the cup 12 again. When leaving the cup 12 , the air flow L carries lighter particles, not shown, of the items to be sorted, which are primarily located on the side wall 19 in the lower region of the cup 12 . The light sorting material taken along then falls into the collecting trough 10 along the arrow direction 20 due to its weight. The sorted material can be removed from the gutter 10 by various measures. A conveyor belt 21 above the bottom 22 of the collecting trough 10 offers a solution to this. The conveyor belt 21 picks up the sorted material and removes it from the collecting trough 10 in a transport direction corresponding to its direction of rotation, which is perpendicular to the plane of the paper.

The invention is not illustrated on and described embodiment limited. It includes also rather all professional training and Modifications in the context of the inventive idea.
