Embodiment Construction

[0012] figure 1 A tower-shaped building G is shown schematically with a conveying shaft G1 and an emptying device arranged alongside it. On the conveying path (for example, the roller conveying path R), the big bag BB is inserted in the conveying hoistway G1. The big bag is usually provided with four hanging rings S distributed around its upper periphery, these hanging rings S are manually hooked on the conveying plate 1a of the conveying unit 1, and the lifting device K lifts the conveying unit upwards in the conveying shaft G1 1, such as figure 1 shown. The lifting device K moves the conveying unit 1 horizontally from the upper position to figure 1 The conveyor unit 1 is then lowered until it abuts against the upper edge of the discharge device 2 .

[0013] In the conveying shaft G1 and above the unloading device 2, guide rails G2 are mounted on the sides, and the guide rollers 1b engage with the guide rails G2 at the conveyor unit 1 so that no twist. In addition, a ho...

Abstract

A method and an arrangement are provided for emptying a Big Bag or similar transport container which is filled with pourable, especially pulverized goods which are not to come into contact with their surroundings, wherein the Big Bag is inserted in a sluice means (2) which is closed off from the surroundings, with simultaneous sealing of the sluice means, which communicates with a processing container (3) for receiving the contents of the Big Bag, whereupon the Big Bag is cut open inside the sluice means by a cutting means (6) provided therein. The empty Big Bag is compressed in a removal zone (A) inside the sluice means (2) and removed into a plastic sack (8) attached to the sluice means (2).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 4 . Background technique [0002] A method and device of this type are known from NL-C-1015987, wherein an annular structure is placed on a large bag receiving support having a rectangular cross-section, and the empty bag is lifted by the annular structure by means of an arm. The large bag is pulled out of the receiving support and provided via an annular cavity to a removal device mounted on the underside of the annular structure. [0003] A Big Bag is a bag-type transport container made of tear-resistant reinforced synthetic fabric, which has a volume of, for example, one cubic meter and which is used to transport (eg sea transport) fillable goods. The big bag has a hanging loop and has to be cut open for emptying, where it is difficult to transfer the powdered goods inside to a container such as a disposal tank without leaking the ...
