- a ■ Posrderrinne is arranged «,

In a known device of this type has die.Ausgabevorrichtung a is itself provided down a funnel-shaped tapered container _v on its underside an outlet opening for the zn separating Good "Below the outlet opening is in a horizontal plane disposed a vibrating plate on which the emerging from the container Good. is moved substantially radially outward. Below the vibrating plate eine.in direction is disposed to the magnetic drum inclined conveyor chute j that ut 6-intercept the falling from the plate and sur magnetic drum leads "In this known device there is no possibility, the flow of material to dose" The material stream changes flaher during the Operation as a function of the filling level of the container, as a result of the different loading of the magnetic drum, the separating effect of the device therefore also changes during operation. There is also no "ability to change the size of the stream of material Because of different grain size and flow ability of the material to compensate =" A significant disadvantage of the known device is that it only ₉ zmn. Separating relatively fine-grained material

· / ■

is suitable because there are larger, especially bulky pieces in the funnel-shaped part of the BeMIters jam and thereby interrupt the material flow «

Also known are Pließdosierexnrichtungen " ₉ in which a conveyor belt is arranged under an output container. A certain length of the conveyor belt loaded with the material is connected to a weighing device. by actuating it, the outlet opening of the container can be enlarged or reduced. Changes. The weight of the material flow is determined by the weighing device and transferred to the control slide9 which the outlet opening of the container in the sense of a compensation of the fluctuation

reduced or enlarged. Such a dose is a · » directions have the advantage that the material flow is precisely metered and kept constant over a longer period of time very complicated built and can only be challenged very little «Bulky parts of the property can be

there is also the outlet opening in the container. jamming »This not only interrupts the flow of material, it can also damage the weighing device"

The invention has for its object to provide a magnetic separation device below, "in which it is possible to supply the magnetic drum ₉ a certain" play bulky amount of material containing at substantially constant current ,.

The invention consists in the fact that the dispensing device has a tiltable container for the goods to be tipped out into the conveyor chute , and in the area of the conveyor chute a device which senses the material flow is provided to control the tilting movement of the container »

The advantage of the invention lies in the fact that the separating su su good with the inventive device, in contrast to the "known apparatuses _s at which the material will be moved through a limited outlet opening on all sides of the dispenser Mus _P 'free of the tiltable container

can flow out, »Bulky parts of the material cannot jam on the way zvoc magnetic drum and thus also not interrupt the flow of material o The control device * which" can, for example, scan the layer height of the flow of material _s transmits changes in the size of the flow of material in such a way a. uf the tilting movement of the container so that the material flow is kept essentially constant by increased or decreased subsequent delivery of the (sutures from the container ”

In one embodiment of the invention, at least one longitudinal section of the conveyor trough is designed as a vibration trough in a manner known per se. By vibrating the trough, the material flow is evenly distributed over the entire width of the trough and the magnetic drum is loosened up. The control device for the tilting movement is arranged in the area of this section «. This has the essential goal part j SaB when the control device detects the layer height of the material flow ₉ a determination of su high values as a result of a non-uniform

Distribution of the goods in the gutter is avoided "'

The control device preferably has an in. Die-gutter, the layer height in d'er Flap open to the touch. Instead of the flap, an optical device like a light barrier can be provided »

In the known separating devices, the material to be separated must first be bent up by a special lifting device. are then filled into the funnel-shaped container of this apparatus "Since such hopper generally made of metal ^ is such Binfüllvorgang associated with a strong noise" further includes to be separated Good often considerable amounts of 3taub _s during the filling of the material in d a. ! Ground the funnel still whirled up to the south. In one embodiment of the invention, the output device therefore has a lifting device for lifting and tipping out the container containing the material to be separated, the Bisse lifting device is from the control: -? Vorric? Atvaig so gs-

controls ₉ that the amount of material carried in the channel is constant. This embodiment of the invention has the advantage that the mixture to be separated can be delivered on level ground _9, preferably in a car or similar storage container ₉ , and on level ground can be pushed into the device »In this embodiment of the invention, the trolley or transport container in which the material to be separated is transported to the device is emptied directly into the channel _9, which saves a filling process»

To achieve an essentially constant flow of material, the lifting device is preferably switched on when the layer height is low in the channel in the sense of increasing the tilted position ₉ 'when the layer height is too high, but in the direction of reducing the tilted position. If the material flow in the channel has the optimal layer height set, the drive of the lifting device is switched off «, The holding positions of the flap filling the layer height of the material flow flowing in the channel are adjustable., Has the container

reaches its uppermost tilted position and the container is emptied ". as a canoe vorgesehen® in one embodiment of the invention device in activity occur, which pivots the Klapp® from the trough and out in the groove find ~ lent material part away be the discharge path to release ₀

B © 1 © ines ¹ embodiment of the invention, the outlet of the gutter is directed against the drum surface and at a distance from it on the side of the drum in the area of an approximately horizontal plane: the drum surface is adjustable. As a result, the device according to the invention can be used for parts of different sizes.

and this ¹ distance is always set to an optimal one »

In a preferred embodiment of the invention, the channel has three portions on _p wherein the first portion is rigidly connected to the lifting device and the aweite portion is pivotally connected to the first portion about a waagrecht® axis and slidably rests on the third groove portion ₉ of a are fixed »ä © n the system toilet is adjustable. This construction makes it possible ο € ate see the Yorlruf

Kinne adapts any tilting of the container well and that the axis of Kippbewegun ^ · of the container does not have to pass through the gutter inlet ₅ which always required a certain constructive effort. In this embodiment, the third channel section is preferably designed as a vibrating channel ₉ "for example by attaching a vibration device to this section = the channel can also have holes that serve for sorting or through which air can be blown in"

In the Ausfübxungsform of the invention shown in the drawing is a container A ₅ which is designed as a trolley _3-in a separator ge = pushed ,, which has an output device sum .Entleeren of the car and a device for dosing the contents of the car in one part and in the other part has a magnetic separating device ₉ which is suitable for continuous operation, has a demagnification device and devices necessary for the transport of the goods.

When the trolley or the container is emptied, the parts to be separated become a magnetic drum or a moving over the magnetic drum. Band P in fanned state and in uniform possible layer height ₈ that does not exceed a bestimmtenyvorsugebenden value should ^ fed »Un to obtain the most uniform possible layer height _9, the emptying of the carriage A is controlled to" da.8 by raising the carriage tin a certain amount of the in this case material sliding out of the car only

wholly or partially out of the viagen ₉ before another lifting takes place. In the embodiment of the invention described here, the trolley A to be emptied is pushed into its lifting device, whereby! 'rager B reach under the trolley A or the bars attached to it (S ¹ Ig ₀ 1 } _o the carriage a lies with its -vorderen · end on ropes C of the lifting device on ο This semi-circular or rectangular holding parts, if necessary can use permanent magnets or electromagnets fitted be ₈ at power draining the system and secure adhesion of the carriage ensure. in 'The example described, the lifting and emptying of the trolley is achieved by an electric hoist E ₉ which is attached to a SraTerse 3D so that it can be rotated and swiveled ο The trolley is swiveled around a horizontal axis during emptying Wagon collapse or lie outside of the wagon ο In the one described here Examples are the girders B, which form part of the lifting device for the trolley, and a bridge F ₅ that is firmly connected to the girders B and extends over the trolley;

rotatable around the axis G- located outside the carriage »An electric hoist E remains permanently connected to the bridge Έ and to a traverse D » A section 11 of a conveyor trough (Pig = 2} firmly connected to a rope H of the lifting device carries at its front end a uii an axis K ,, rotatable trough-shaped extension _9, the I2 is connected firmly or elastically connected to a frame on L ei = nen chute section 13 "is slidable"

Above the Rinnenabsehnitt 13 a flap M is "placed which senses the layer height, and thus the Pördergeschwindigkeit of the material to be separated and controls the tilting of the carriage" of the flap causes dureh known Sehaltelementβ ₉ such _e 'B. Flikro switch and / or safety cover or relay three different operating positions of the electric train ess "Up" - "Stop" - "Down". This means that when the flap M is lifted by an amount to be specified depending on the material and the separation speed, which is equal to or proportional to the layer height, the electric cable is switched off "by attaching a switch or contact to _{Z 0} B _0, that it is actuated by the flap at this point, or

since then the downward movement of the electric train causing contact is separated »lowers see the flap» because the material flow decreases, the Electric hoist E switched on again. This happens when there are fewer ropes from the wagon »

If large amounts of material suddenly appear, the flap M moves to an even higher position (Figo 3) o In this position, the electric hoist is switched to downward movement ₉ whereupon the layer height decreases because no material or less material is being delivered. The flap M lowers here again ^ when the "Halt" position is reached, the electric pull stops »When the layer height decreases further, the flap M lowers and. causes the wagon to move up again Α, which means that emptying is continued. The layer height and the sensitivity to separation can be given ₉ by S = B, the switch actuated by the flap M being kept adjustable relative to the direction of rotation of the flap M or by the pivot point of the flap can be changed ο When the upper end position of the trolley is reached, a switch is actuated ₉ which either controls the electric hoist

switches to emptying or activates a lifting magnet which brings the flap M to the "Down" position and opens it ₉ so far that any ropes still on the channel H ₉ 12 and 13 can get aur £ r separate o The carriage lowers accordingly »The flap M can be held in its initial position (" open "position) by gravity, springs or magnets. Upon reaching the starting position of the carriage A of the switch, which brings the example "on switch .on" off "position as held by its own power, and if necessary simultaneously actuates the solenoid is _s

Lim loosen the material as much as possible from the electromagnetic drum susufführungj, is under the gutter = »section 13 an electromagnetic vibrator H or Unhealth motor attached "The material on the chute" is kept in motion by this and loosened = if necessary, an electromagnetic conveyor trough can be installed instead of the trough 13 ^ whereby by regulating the amplitude the delivery rate can be specified in it.

The material of the magnetic drum is j Yon the chin portion 13 reaches _0, the material to be separated to the magnetic drum O For a proper separation of workpieces and Beigabegut to reach "supplied borrowed as shown in Pig" 0 since illustrated. 1 The magnetic drum 0 rotates in the specified direction of rotation »It is driven Z ₀ B ₀ by a directly flanged gear motor« In the direction of rotation specified here, all ferromagnetic parts are guided upwards, while the non-magnetic parts fall down into a collecting container A2 «If the ferromagnetic ropes are to leave the system demagnetized ^ a band P is expediently guided around the magnetic drum 0 (Fig. 1), which is guided over a pulley Q through a demagnetizing device B. ο The magnetically separated and demagnetized files are produced the point A3 ⁹ from the belt and into a container A3 o The containers A2 and A3 ■ are designed as trolleys in the present example thin, wet slips ₅ that stick to the tape fall off »

The distance between the magnetic drum and vibrator or feed chute 13 is expediently kept adjustable so that the device can be used for different sized ropes »This distance must be set to an optimal value in each case _{9 in} order to achieve a perfect separation of different workpieces and added goods» because the ferromagnetic parts should cover the longest possible way leaving the channel up to the drum _{surface ^ so that 9} non-ferromagnetic ropes sticking to it fall off Umlenkrolie Q take place «If the distance changes that have to be made frequently, either the feed channel 13 or the magnetic drum 0 and the deflecting roller Q are placed on a separate frame or special rails ₉ which are placed on the base frame by means of customary structural elements for longitudinal guides (e.g. ball guides) are stored and therefore enable easy movement »lame or splints should be locked at any point!
