Abstract

A folded box gluing machine for the processing of folded box blanks includes at least one feeder unit arranged to transport the folded box blanks to downstream processing stations including a folding station, a glue applicator unit, a transfer station, a gathering and pressing mechanism, and a safety mechanism for a machine component presenting a danger to the human operator defined by a light curtain. The safety mechanism can be deactivated via a mobile operator unit, and the operator unit is designed such that it can only be operated with both hands.

Claims

1. A folded box gluing machine for processing folded box blanks, comprising:

at least one feeder unit arranged to transport the folded box blanks to downstream processing stations including a folding station, a glue applicator unit, a transfer station, a gathering and pressing mechanism; and

a safety mechanism for a machine component presenting a danger to an operator defined by a light curtain integrated in uprights arranged at sides of the folded box gluing machine;

wherein

the safety mechanism is deactivated via a mobile operator unit, which includes at least two contacts, and the at least two contacts can only be operated with both hands at the same time by the operator.

2. The folded box gluing machine according to claim 1, wherein the at least two contacts are disposed on opposite sides of the mobile operator unit.

3. The folded box gluing machine according to claim 1, wherein the at least two contacts are arranged on the upper side and lower side of the mobile operator unit.

4. The folded box gluing machine according to claim 1, wherein each of the at least two contacts is a press switch.

5. The folded box gluing machine according to claim 1, wherein the at least two contacts include a device arranged to perform capacitive measurement.

6. The folded box gluing machine according to claim 1, wherein the mobile operator unit is connected by a cable to the safety mechanism.

7. The folded box gluing machine according to claim 1, wherein the mobile operator unit is connected wirelessly via antennas to the safety mechanism.

8. The folded box gluing machine according to claim 1, wherein a status of the safety mechanism is indicated by at least one of an acoustic sign and an optical signal.
