DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an apparatus for emptying single or multi-walled packages, for example sacks (large sacks), bags etc., which have a discharge mouth which is formed by a part of the package wall or a specially provided socket.
THE STATE OF THE ART/TECHNICAL PROBLEM
In the handling of certain bulk materials, it is, int. al. for reasons of hygiene, desirable to provide for as good as completely enclosed filling and emptying of the utilized package, in particular in the handling of foodstuffs and starting materials for the manufacture of foodstuffs, medicines etc. In such cases, the package normally consists of single or multi-walled sacks (large sacks), bags or the like. In order to facilitate enclosed emptying of such a package, it is normally provided with an under socket.
Emptying via this under socket has, however, proved to entail such problems as the formation of folds which render the emptying operation more difficult.
The object of the present invention is to realise an apparatus which allows for emptying of single or multi-walled packages with an under socket or the like, without incurring any problems in fold formation, in which case it should also be possible to effect emptying in an enclosed manner.
SOLUTION
The present invention satisfies the above-disclosed object in that the apparatus described by way of introduction is provided with a support for carrying the package which is to be emptied with the discharge mouth downwardly directed and extending through an opening in the package support in order to surround a ring in an outlet member, which ring is shiftable for stretching the package wall or the socket. Advantageously, the ring is located about a frame for supporting the package wall or socket, primarily when the ring is located in its shifted, lower position. It is suitable that the outlet member be fixedly disposed beneath the opening in the support, that the frame be upwardly directed, and that the ring be mounted by means of a bellows device which extends about the frame. Preferably, the frame has at least one shoulder on which the ring rests in its upper position in which the package wall or socket is applied thereon. For controlled emptying of the package, it is appropriate that the outlet member be provided with an outlet portion which in its turn is provided with a throttle.
ADVANTAGES
In an apparatus according to the present invention, stretching of the socket takes place during emptying of the package, whereby making for enclosed emptying and preventing the formation of folds which would render the emptying procedure more difficult.
DESCRIPTION OF THE ACCOMPANYING DRAWINGS
The invention will be described in greater detail below with reference to the accompanying drawings, in which,
FIG. 1 is a schematic side elevation of one embodiment of an apparatus according to the present invention; and
FIG. 2 shows, on a larger scale, a section through a part of the apparatus of FIG. 1.
The embodiment of an apparatus according to the present invention shown on the drawings is provided with a package support 1 with stays 2, 3 and 4. The stays 2-4 prevent a large sack which is placed in the support 1 from falling over. The support 1 is substantially bowl-shaped and has a centrally located bottom opening 5. Through this opening, the lower socket of a package or large sack which is to be emptied may extend. Furthermore, the support 1 is provided with suspension members 6 and 7 for cooperation with, for example, the forks of a fork-lift truck.
Beneath the opening 5, there is disposed an outlet member 8 which is suspended from the support 1 by means of cross stays 9 and 10 and vertical stays 11 and 12. Although but two cross stays and two vertical stays are shown, the apparatus my be provided with two further cross stays and two further vertical stays, if desired. Furthermore, the outlet member 8 is provided with a throttle portion 13 which includes a throttle 15 operable by means of a handle 14 for controllable emptying of a package connected to the ou
