Abstract
Various embodiments of the present disclosure provide a random case sealer configured to interrupt the case-sealing process upon detecting an object between the top-head assembly and the top surface of the case.
Claims13
A case sealer comprising:
- a base assembly;
- a top-head assembly supported by the base assembly;
- an actuator operably connected to the top-head assembly to move the top-head assembly relative to the base assembly;
- a first sensor configured to transmit an object-detected signal responsive to detecting an object and an object-undetected signal responsive to no longer detecting the object;
- a second sensor configured to transmit an object-detected signal responsive to detecting the object beneath the top-head assembly;
- a tape cartridge downstream of the second sensor and configured to apply tape from a tape supply to the object;
- and
- a controller communicatively connected to the first and second sensors and operably connected to the actuator, the controller configured to:
- receive a first object-detected signal from the first sensor;
- responsive to receiving the first object-detected signal from the first sensor, control the actuator to begin raising the top-head assembly;
- after receiving the first object-detected signal from the first sensor, receive a first object-detected signal from the second sensor;
- and
- after receiving the first object-detected signal from the second sensor and responsive to receiving a second object-detected signal from the first sensor while the object is beneath the top-head assembly and before the object has reached the tape cartridge, control the actuator to begin raising the top-head assembly.
