DE2557014A1 - Bulk goods transfer rig for conveyors - has container with conveyor base and controlled tilting trapdoors - Google Patents

Abstract

The transfer station for a bulk goods conveyor receives the contents of transportation containers and continuously supplies goods steadily over a longer period to the conveyor. The containers tilt towards the front and the rear. The transfer station consists of a flat container, open at the top, the base of which is formed partly or completely as a conveyor. Sections of the container are rigid and other tiltable. The front wall of the container simultaneously synchronises the conveying capacity of the transfer container and the conveyor. All tiltable sections are automatically controlled by limit switches and/or time relays, actuated by the material flow.

Description

Transfer device for bulk goods to conveyor systems

The invention relates to a transfer device for bulk goods Conveyors that take up the contents of transport containers in a short time can and without loss of time to the downstream conveyor system over a longer period of time Period continuously passes and is carried out in such a way that both sideways and backward-tipping vehicles can also deliver their load.

Such devices are known in the form of said output hoppers. In order to avoid unnecessary waiting times for the vehicles, these feed hoppers can be used E.g. picking up a whole truck load of gravel at once, over a longer period of time is continuously transferred via chutes to a bucket elevator or conveyor belt.

A trouble-free emptying of this feed hopper is only then q guaranteed if their walls are arranged very steeply, i.e. these feed hoppers become correspondingly high. Vehicles can be theirs Charge only then Dispense directly into these feed hoppers if they are built into the ground or appropriate ramps are present. Installation in the ground causes costs for shafts and extended conveyor systems. Ramps take up a lot of space and are also expensive. (Feed funnel for a truck load require e.g.

Shafts of (, - 7 m deep).

There are also known devices that circumvent these disadvantages and are based on the principle of concrete transfer silos for construction sites. It is about So around funnels that pick up the truck load in a lowered position and then move hydraulically to emptying position. With these (transfer facilities a maximum ramp or

Shaft depth of 1 ni required. A major disadvantage of these solutions is the time lost by raising and lowering the funnel, which is caused by a larger dimensioned downstream conveying device can be compensated for got to.

The object of the invention is to overcome the disadvantages of the known overhead transfer devices to avoid.

This object is achieved by a transfer device that also a maximum of a ramp or shaft depth of 1 m is required, i.e.

is designed as a flat Geüiß that both sideways and Backward tipping vehicles can deliver their load. The bottom of the jar will formed by a conveyor or contains such. The side walls of this Vessels are either rigid or rigid and movable or all movable, i.e. tiltable arranged or there are lance parts of the vessel.

The invention is also designed so that the in the conveying direction located front wall of the vessel at the same time to coordinate the delivery rate the transfer device to the conveying capacity of the downstream conveying device serves.

In addition, the sequence of movements of the tiltable vessel parts is automatic controlled by limit switches and / or time relays actuated by the material flow.

The conveyor system starts while the vehicle is being unloaded with the emptying of the overhead device (l on the downstream bucket elevator or Tape. As a result, the hydraulically tiltable uberga will be installed occurring loss of time avoided.

The invention is explained in more detail using two examples: for the first Example shows a schematic representation of Fig.l a floor plan in a horizontal position Fig.2 a front view in a horizontal position Fig.3 a side view in an inclined position.

For the second example with rigid side walls, the schematic shows Representation Fig.4 a floor plan.

Fig.l-3 The downstream conveyor device (1) (here a bucket elevator) with the inlet funnel (2) is from a transfer device, consisting of a Conveyor belt (3), the tiltable vessel parts (4), the front walls (5) and (6), charged. The vessel parts (4) are removed from the horizontal position by hydraulic cylinders (7) movable, for this purpose they are rotatably mounted in the hinge points (8).

After tipping the bulk goods from the vehicle into the transfer device in direction (9), the conveyor belt (3) is switched on if it is not already running and of course the conveyor (1) beforehand.

The vessel parts (4) remain in a horizontal position until the Limit switch (1O) switches when the conveyed material is removed from the conveyor belt (3) and so that the hydraulic unit starts to operate the cylinder (7). The cylinders (7 ') move the (; efäßteile (4) slowly in the emptying position (11) (about 450 - 600). The belt is switched off again via a time relay.

While the front wall (6) allows material to fall over the belt prevented, the front wall (5) also serves to limit the layer height and thus to match the conveying capacity of the conveyor belt (3) to the conveying capacity the downstream conveyor device (1).

Instead of the two vessel parts (4) that are attached to the in the first example Long sides of the conveyor belt (3) are arranged, is also only a tiltable vessel part conceivable that releases its content in the direction (9) on the conveyor belt (3).

Fig.4 The transfer device consists of the conveyor belt (3) and a vessel, the bottom of which is entirely from the conveying device (12) (in the example a wide conveyor belt) and the side walls (13) are rigidly arranged. That Conveyor belt (3), which conveys at right angles to the conveyor belt (12), has the task of the wide material flow from the conveyor belt (12) to one for the inlet hopper (2) to bring the downstream conveyor device to the appropriate size. The front wall (14) is again used to coordinate the funding services of the delivery facility and the downstream conveyor.
