Definitions

• the invention relates to a device for storing bulk material which tends to form bridges, in particular snippets made of cardboard or the like.
• a bunker which can be loaded with bulk material and which discharges it below is provided, which has a plurality of floors arranged one above the other, each of which has at least one passage opening which can be loaded with bulk material by means of a clearing device assigned to the floor in question.
• the bottom floor can be expediently covered by at least one chamber conveyor that leads past at least one assigned passage opening.
• these measures result in a simple, yet reliable, volume portioning of the bulk material. This ensures that, despite the unavoidable fluctuations in the specific density of this material, for example in the manufacture of cardboard and the like consisting of chips, portions of substantially the same volume can be achieved which correspond to the filling of a chamber of the chamber conveyor.
• a further advantageous measure can consist in the bunker having a central, standing shaft which can be driven by means of an associated drive device and from which at least one clearing element projects in the region of each floor.
• a wiping edge facing the chamber conveyor can be provided in the area of the front edge of the passage opening of the bottom floor. This ensures that the chambers of the chamber conveyor are only filled up to their upper chamber edge and excess material is scraped off and thrown into a subsequent chamber, which ensures a high portioning security.
• FIG. 1 shows a vertical section through an inventive storage device for snippets made of cardboard.
• the storage device on which the drawing is based contains a bunker 1 into which cardboard snippets produced in a manner known per se are thrown in the region of its upper end.
• the bunker l be open to the top.
• the bunker 1 is provided with an inlet flap 2 provided in the area of its upper edge, to which a chute 3 is assigned, which can be loaded with snippet material by means of a conveyor belt 5 arranged in an increasing manner and provided with drivers 4.
• the bunker 1 which can be designed as a square bunker or as a cylindrical round bunker, has a lower floor 6 and a plurality of intermediate floors 7, which are arranged at a distance above it and are staggered in height relative to one another and parallel to the lower floor 6.
• the intermediate floors 7 result in a division of the bunker height into several sections.
• the floors 6 and 7 are formed as horizontal flat floors. Each floor 6 or 7 has a hatch-shaped passage opening 9 arranged close to the outer wall, via which snippet material can be thrown off onto the next floor or can be ejected from the bunker 1 in the area of the bottom floor 6.
• the passage openings 9 of the Soils located one above the other are initially offset from one another. In the example shown, each with a passage opening 9, the offset is 180 °.
• a clearing device is assigned to each tray 6 and 7, which sweeps over the assigned tray and the chip material carried along with it transported to the passage opening 9 of the associated base 6 or 7.
• the bunker 1 is provided with a central, standing shaft 10 which penetrates all floors 6, 7 and is provided above each floor 6, 7 with a radially projecting clearing arm 11 which sweeps over the respectively assigned floor and extends to the periphery of the bunker.
• circular inserts can be provided to avoid dead corners that cannot be reached by the clearing arms.
• the bunker 1 can be provided with at least one viewing window extending over its entire height.
• a wall can simply be made of transparent material.
• the clearing arms 11, which can be designed as rod or profile sections, are circumferentially offset from one another, here likewise by 180 °.
• the rotatably mounted and axially supported shaft 10 can be driven in the U direction by means of a drive device 12 acting on a shaft end, here on the upper shaft end. at the drive device 12 can be a geared motor.
• a drive device 12 acting on a shaft end, here on the upper shaft end. at the drive device 12 can be a geared motor.
• the configuration of said passage opening 9 of the bottom floor 6 corresponds to the cross section of a chamber or a plurality of two or three chambers of said chamber conveyor 14. Accordingly, a window-shaped configuration of said passage opening 9 results.
• the passage openings of the other floors 7 can have the same configuration.
• the volume of the chambers of the chamber conveyor 14 corresponds to the volume which is required when processing the shredded material a little at a time, for example into packaging bags.
• a scraper bar 15 is provided in the area of the front edge of the passage opening 9, which is gripped by the chamber conveyor 14 and bridges the distance between the lower edge of the passage opening 9 and the upper edge of the chamber conveyor 14. Accordingly, excess material is stripped off by the scraper bar 15 and thrown into the subsequent chamber of the chamber conveyor 14.
