Definitions

• the invention relates to a device and a method for contamination-free filling or emptying of bulk materials from an outlet of a reservoir, for example, in a smaller individual container.
• the bulk materials to be filled are those of the food or pharmaceutical industry, one of the main requirements is to reliably ensure that contamination of the bulk material and the parts in contact with it does not occur with the environment or the bulk material is classified as hazardous and an operator should not come into contact with the substance.
• a problem with all these known devices and methods is that, especially at the time of replacement of a spent Schlauchfo- lienvorrates contamination of the inner volume of the tubular film supply can not be prevented because at least when attaching the beginning portion of the new Schlauchfolienvorrates at the outlet of the corresponding reservoir, the inner volume of the Hose film stock is freely accessible. Therefore, there has long been a requirement to eliminate this risk of contamination without abandoning the handling advantages of an endless liner system and also making the device suitable for filling bags or the increasingly used big bags.
• the object of the invention is therefore to propose a device and a method of the type mentioned at the outset which overcomes the disadvantages of the prior art and, in particular, makes possible a completely contamination-free filling of bulk goods, in particular using an endless liner system.
• the device proposed in the context of the invention for the contamination-free filling of bulk materials from an outlet of a storage container comprises a tubular film supply provided on a carrier tube with inlet and outlet openings, which can be filled with bulk material through the carrier tube, as is the case on the market available to endless Linder systems.
• the outlet of the reservoir, a first connection and obturator and the inlet opening of the support tube is associated with a second connection and obturator, which are sealingly abuttable to each other and reversibly apparent to form a through-opening for the bulk material to be filled.
• the invention thus proposes to provide not only the outlet end of the reservoir with an associated connection and obturator, so that it can be sealed off from the environment, but also communicating with the tubular film supply inlet opening of the support tube with a second connection and obturator provided so that it can not lead to contamination of the interior of the tubular film supply during storage and handling of the support tube with the tube film supply arranged thereon. If the provided on the support tube tube film supply is required in the context of filling, the two connecting and shut-off are sealed to each other for conditioning and thus seal against the environment and are only then reversibly opened to form a through hole for the bulk material to be filled to to start the filling process.
• the inlet opening of the support tube via a hose portion with the second connection and obturator - A - connected while according to an alternative proposal of the invention, an end portion of the tubular film supply inside the carrier tube is arranged to extend and is fastened in the region of its end opening on the second connection and obturator.
• the end section of the tubular film supply thus forms an inner lining for the carrier tube.
• the tube section connecting the inlet opening of the carrier tube to the second connecting and obturating device is formed with a dedusting connection, to which a suction device can be connected for sucking up accumulating dust within the tube foil supply during the filling of the bulk goods.
• a dedusting connection can, of course, also be provided at the end section of the tubular film supply if this is arranged running as a lining through the carrier pipe. Via the dedusting connection, displaced air can be returned to the storage container even when filling the tube film supply.
• the tube section connecting the inlet opening of the carrier tube to the second connecting and obturator also causes a decoupling of the carrier tube and the tube film supply to be filled from a weighing device for the filled bulk material.
• one of the connecting and shut-off elements is equipped as an active part with drive means for reversible opening, while the other connection and obturator as passive part has no own drive means for reversible opening, but non-positively connected to the active part and by means of Drive means is also reversibly apparent.

• the reverse configuration is also conceivable.
• At least one of the connecting and shut-off devices is operable as a metering device for the bulk material to be filled, i. the reversible formation of the passage opening is used not only for the release of a passage cross-section for the bulk materials, but also for the quantitative metering thereof during the filling process.
• the active part is particularly appropriate to operate the active part as a metering device for the bulk materials to be filled.
