Separating device and method for separating a blister tube, and packaging device comprising a separating device

A method for separating a blister tube having a plurality of blister pouches, the method comprising:

• arranging a separation aid between individual blister pouches of the blister tube;
• feeding the blister tube to a blister tube feed device comprising a first transport means and an associated first transport means bearing;
• guiding a first portion of the blister tube, clamped between the first transport means and the first transport means bearing, in such a way that slippage relative to the first transport means is prevented;
• moving the blister tube via the clamped first portion by the first transport means in a transport direction at a feed speed;
• feeding the blister tube to a blister discharging device arranged downstream of the blister tube feed device and comprising a second transport means and an associated second transport means bearing, wherein the second transport means and the second transport means bearing each have a circular sector roller comprising at least one sector element, the circular sector rollers being matched to one another;
• clamping, by the matched circular sector rollers, a second portion of the blister tube between the second transport means and the second transport means bearing in a slip-resistant manner relative to the second transport means so that a separation aid is arranged between the blister tube feed device and the blister discharging device;
• and
• exerting, with the aid of the second transport means, a tensile force on the second portion of the blister tube in the transport direction, the tensile force being dimensioned in such a way that the second portion of the blister tube is separated from the first portion of the blister pouch at the separation aid.

A packaging device for small piece goods, comprising:

• a packaging material guide device for receiving an elongate packaging material web, the packaging material guide device configured so that the elongate packaging material web is shaped for receiving small piece goods and extends in a movement direction;
• a longitudinal joining device arranged downstream of the packaging material guide device, the longitudinal joining device configured to join together the shaped packaging material web at a packaging material overlap region in the movement direction of the packaging material web;
• a transverse joining device arranged downstream of the packaging material guide device, the transverse joining device configured to join together the shaped packaging material web at predetermined distances transversely to the movement direction to form a transverse joining region, as a result of which a blister tube comprising a plurality of blister pouches is formed, the transverse joining device comprising two joining devices, of which at least one joining device is movable transversely to the movement direction;
• and
• a separating device comprising:
• a blister tube feed device comprising a first transport device and an associated first transport device bearing configured so that a first portion of the blister tube is guided, clamped between the first transport device and the first transport device bearing, in a transport direction so that slippage relative to the first transport device is prevented;
• a blister discharging device arranged downstream of the blister tube feed device, the blister discharging device comprising a second transport device and an associated second transport device bearing configured so that a second portion of the blister tube is clamped between the second transport device and the second transport device bearing in a slip-resistant manner relative to the second transport device, wherein the blister tube feed device and the blister discharging device are arranged in such a way that between the first portion and the second portion of the blister tube, a separation aid is arranged between two blister pouches;
• a first drive coupled to the first transport device;
• a second drive coupled to the second transport device;
• a control device coupled to the first drive and to the second drive;
• and
• one of:
• the first transport device has a first transport double roller, the first transport double roller and the first transport device bearing configured so that the first portion of the blister tube comprises opposing side regions of the blister tube;
• and
• the second transport device has a second transport double roller, the second transport double roller and the second transport device bearing configured so that the second portion of the blister tube comprises opposing side regions of the blister tube,
• wherein the control device is configured to temporarily exert, with the aid of the second transport device, a tensile force in the transport direction on the second portion of the blister tube, the tensile force being dimensioned in such a way that the second portion of the blister tube is separated from the first portion of the blister pouch at the separation aid.
