Automatic bundling tool device with guiding unit for deformed and/or loose one-piece ties
An automatic bundling tool device (ABT) for bundling a bundling good via a one-piece-tie (OPT). In aspects, an ABT includes a holding unit configured to receive, hold, and release a respective OPT; a motion guiding unit configured to guide a motion of the holding unit between a receiving position and a releasing position; a claw unit configured to guide a strap of the respective OPT around the bundling good; and a tip guiding unit with at least one guiding flap element configured to guide a tip of the respective OPT towards an entrance of the claw unit.
1 . An automatic bundling tool device (ABT) configured for bundling a bundling good through use of a one-piece-tie (OPT), the device comprising:
a holding unit configured to receive, hold, and release a respective OPT provided to the ABT from an external reservoir of OPTs;
a motion guiding unit configured to guide a motion of the holding unit between a receiving position of the holding unit where the holding unit receives the respective OPT and a releasing position of the holding unit where the holding unit releases the respective OPT;
a claw unit configured to guide a strap of the respective OPT around the bundling good; and
a tip guiding unit with at least one guiding flap element configured to guide a tip of the respective OPT towards an entrance of the claw unit when the respective OPT is moved towards the releasing position by the holding unit moving from the receiving position to the releasing position,
wherein:
at least one distance between an inner surface of the at least one guiding flap element and an OPT track along which the respective OPT is moved from the receiving position to the releasing position decreases in a direction towards the claw unit,
the at least one distance is measured perpendicular to a longitudinal axis of the OPT track as a y-distance in a direction of thickness of the respective OPT and as a z-distance in a direction of width of the respective OPT, and
the holding unit is configured to move the at least one guiding flap element.
2 . The automatic bundling tool device of claim 1 , wherein the OPT track is straight.
3 . The automatic bundling tool device of claim 1 , wherein the at least one guiding flap element forms a section of a funnel narrowing towards the claw unit, where a narrow end shapes a gate that is configured to guide the tip into the entrance of the claw unit.
4 . The automatic bundling tool device of claim 1 , wherein the at least one guiding flap element further comprises converging surfaces that enclose an angle of less than 90 degrees.
5 . The automatic bundling tool device of claim 3 ,
wherein the at least one guiding flap element is arranged movably relative to a body of the ABT, the guiding flap element movable between a guiding position and a clearing position,
wherein in the guiding position an end of the at least one guiding flap element is proximal to a proximal end of the claw unit, the proximal end forms at least one of the gate or a part of the gate that guides the tip of the OPT into the entrance of the claw unit, and
wherein in the clearing position a distance of the proximal end and the OPT track is increased as compared to the guiding position.
6 . The automatic bundling tool device of claim 5 , wherein the at least one guiding flap element is arranged rotatably around a respective rotation axis.
7 . The automatic bundling tool device of claim 6 , wherein the at least one guiding flap element is arranged rotatably around a respective rotation axis with at least one of the rotation axis running perpendicular to the OPT track or the rotation axis having a non-zero distance from the OPT track.
8 . The automatic bundling tool device of claim 7 ,
wherein the rotation axis runs parallel to the width direction of the respective OPT.
9 . The automatic bundling tool device of claim 5 , wherein the at least one guiding flap element is configured to be held in the guiding position by a spring element and is configured to be moved into the clearing position by the holding unit approaching the claw unit.
10 . The automatic bundling tool device of claim 9 , wherein the at least one guiding flap element is configured to be moved into the clearing position by a mechanical interaction of the holding unit with the at least one guiding flap element.
11 . The automatic bundling tool device of claim 5 , wherein the at least one guiding flap element is configured to be locked in the clearing position by a locking element, and wherein the locking element is configured to release the at least one guiding flap element when a distance between the holding unit and the at least one guiding flap element exceeds a preset distance.
12 . The automatic bundling tool device of claim 1 , wherein the inner surface of the at least one guiding flap element is orientated towards the OPT track.
13 . The automatic bundling tool device of claim 12 , wherein the inner surface of the at least one guiding flap element includes at least one of a smooth surface or a coated surface.
14 . A method for bundling a bundling good through use of a one-piece-tie (OPT) with an automatic bundling tool device (ABT), the method comprising:
providing a respective OPT to the ABT from an external reservoir;
moving the respective OPT towards the bundling good by a holding unit with a tip of the respective OPT ahead;
if the respective OPT has a bent strap, guiding the tip of the respective OPT towards an entrance of a claw unit perpendicular to a longitudinal axis of an OPT track in a direction of a width of the respective OPT, by at least one guiding flap element positioned in a guiding position;
after the tip has entered the claw unit, moving the at least one guiding flap element in a clearing position further away from an OPT track than in the guiding position with a movement of the holding unit; and
guiding a strap of the respective OPT around the bundling good and through a head of the respective OPT, by the claw unit.
