Transport unit for coils, and arrangement comprising the transport units

A transportation unit for transporting a plurality of coils, comprising:

• a pallet;
• and
• a plurality of bags stacked in layers on the pallet,
• wherein each of the bags contains a plurality of coils of yarn, filament, or thread arranged in a first layer such that centers of the coils in the first layer are arranged parallel with respect to each other such that an axial direction of the center of each coil in the first layer is approximately perpendicular to an extension direction of the pallet, and wherein the extension direction is a horizontal direction of the pallet when the pallet is in use;
• wherein the pallet comprises a plurality of protrusions with accordion-like convolutions extending from a bottom surface of the pallet and reinforcement valleys connecting each of the plurality of protrusions;
• wherein each bag holds the coils contained therein in a self-supported structure, and wherein the bag lies close against the coils inside the bag such that a stable bag assembly defined by the bag holding the coils having approximately a fixed geometry is provided;
• wherein an intermediate sheet lies on top of a final layer of a bag or bags of the transportation unit, the intermediate sheet serving as a supporting surface for a further transportation unit placed on top of the transportation unit;
• wherein the bags and the pallet are fixed together by a fixation belt which surrounds the transportation unit circumferentially in a direction approximately perpendicular to the extension direction of the pallet;
• wherein each bag has an opening at a side next to a side face of the first layer of coils and/or a second layer of coils;
• wherein each bag is a single opening bag, and wherein the bag is configured to be closed at an end with the opening by rolling the bag end and by roping up each respective corner ear of the bag, which are obtained after the rolling up of the bag end;
• wherein the respective corner ears of the bag are adapted to be gripped by a user to remove the bag from the pallet;
• and
• wherein the pallet is configured such that two bags of the plurality of bags substantially cover a top surface of the pallet, so that two bags are arranged on the pallet in each layer, wherein the two bags in each layer are arranged adjacent to each other along a transverse axis of the pallet, wherein there are provided at least more than two layers of bags in a stacking direction on the pallet, and wherein each bag of the plurality of bags has the end with the opening facing a first longitudinal edge of the pallet such that the corner ears of each bag of the plurality of bags are aligned along the longitudinal edge.
