US 10,472,168 B2 · Flexible container liner wringing device

Abstract

A liner wringing device (10) is disclosed for use with a container liner. The wringing device includes a housing (30) with an internal cavity which houses the mechanical components of the wringing device. The housing defines a central liner compression channel (40). The internal components include a bottom support plate (42) with a central opening 43 aligned along the central channel. The wringing device also includes a drive assembly (44) formed by four elastomeric rollers (45) positioned so that the peripheral contact surfaces (50) are aligned generally tangentially with the central channel. The four rollers are each mounted to a drive shaft/axle which includes bevel gears which are meshed so that all four rollers rotate in simultaneous, synchronic rotation through the actuation of a pneumatic air gear motor (57).

Dependent claims

An intermediate bulk container liner wringing device for use with an intermediate bulk container flexible liner containing material therein, said wringing device comprising;

a mounting plate having an opening therein;
a first roller rotatably coupled to said mounting plate directly adjacent said opening of said mounting plate;
a second roller rotatably coupled to said mounting plate directly adjacent said opening of said mounting plate;
a third roller rotatably coupled to said mounting plate directly adjacent said opening of said mounting plate, a fourth roller mounted directly adjacent said opening of said mounting plate;
a drive mechanism directly coupled to said first roller, coupled to said second roller, coupled to said third roller, and coupled to said fourth roller;
and a guide block positioned between each adjacent pair of said rollers configured to guide the alignment of said rollers and to prevent the gathering of the intermediate bulk container flexible liner between adjacent said rollers during use,
whereby the actuation of the drive mechanism causes the first, second and third roller to rotate thereby pulling the flexible liner between the rollers through the opening of the mounting plate.

An intermediate bulk container liner wringing device for use with an intermediate bulk container flexible liner containing material therein, said wringing device comprising;

a first pair of generally axially parallel aligned rollers;
a second pair of generally axially parallel aligned rollers, said second pair of generally axially parallel aligned rollers being generally axially perpendicular to said first pair of generally axially parallel aligned rollers;
wherein each said roller of said first pair of generally axially parallel aligned rollers is spaced away from each other to define a liner compression channel there between, and each said roller of said second pair of generally axially parallel aligned rollers is spaced away from each other to further define said liner compression channel there between, a drive mechanism coupled to both said first and second pair of generally axially parallel aligned rollers;
and a guide positioned between each adjacent roller of said first and second pair of generally axially parallel aligned rollers configured to guide the alignment of said rollers and to prevent the gathering of the intermediate bulk container flexible liner between adjacent rollers during use,
whereby the actuation of the drive mechanism causes the first and second pair of generally axially parallel aligned rollers to rotate thereby pulling the liner through the linear compression channel between the rollers.
