Wrapping apparatus and method with a security mechanism and a drive blocking mechanism

Method for wrapping an object

• by using a wrapping apparatus comprising
• an object support for supporting from below an object to be wrapped,
• a wrapping unit with at least one holder for a wrapping material reservoir,
• a wrapping unit drive,
• at least one barrier, and
• a blocking mechanism,
• wherein a wrapping unit part comprising the or at least one holder of the wrapping unit is rotatable with respect to the object support,
• wherein the or at least one barrier is movable with respect to the wrapping unit between
• a protecting position and
• at least one further position,
• wherein the method comprises the steps that
• the object to be wrapped is placed on the object support such that the object is supported from below by the object support,
• the wrapping unit drive rotates at least temporarily the rotatable part of the wrapping unit around the object support
• such that the object on the object support is wrapped into at least one web of wrapping material taken from the or one wrapping material reservoir kept by the or one rotated holder, and
• the or every moveable barrier is in the protecting position while the wrapping unit part is rotated such that the or every barrier provides a mechanical safety mechanism,
• wherein the method comprises a sequence which is performed at least once and which includes the steps that
• the or at least one barrier is moved into the or one further position and
• the blocking mechanism inhibits the wrapping unit drive to rotate the wrapping unit
• if the or at least one moveable barrier is in the or one further position,
• wherein
• the blocking mechanism comprises
• at least one mechanical interrupter and
• at least one interrupter connector,
• wherein the or every interrupter is movable between
• an interrupting position and
• at least one further position, and
• wherein the or every interrupter connector mechanically connects the or one movable barrier with the or one interrupter such that every movable barrier is connected with the or at least one interrupter, and
• wherein the step that the blocking mechanism inhibits the wrapping unit drive to rotate the rotatable wrapping unit part comprises the steps that
• the or one interrupter connector transfers the movement of the barrier into the further position onto the or one connected interrupter
• such that this interrupter is moved into the interrupting position and the interrupter being in the interrupting position interrupts a supply connection for the wrapping unit drive,
• thereby deactivating the wrapping unit drive.
