SENSORS
A.6a
Feed Sensor
The feed sensor is used to detect the feeding of a sheet of paper from the
feeder onto the transfer conveyor. The deed sensor is a proximity sensor that
also signals the glue gun tip sealers to open when the lead edge of the sheet
is detected. This sensor also verifies sheet count. When the inserter mode is
turned on, the sensor detects the trailing edge of the sheet to turn the feed
clutch on to pulse feed the next sheet from the singulator. Pulse feeding is
activated only when insert mode is turned on.
A.6b
Double Detect Sensor
The double detect sensor is an infrared through-beam sensor. The sensor is
used to detect the feeding of more than one sheet at a time. The voltage
value sent to the CPU from the double detect sensor corresponds to the
thickness of the paper. This allows the CPU to detect double sheets being
fed.
A.6c
Feeder Encoder
The encoder is connected to the transfer drive shaft by a timing belt. The
encoder sends the CPU sixty (60) pulses for every revolution of the shaft.
The CPU calculates the speed at which the M-40 is operating.
A.6d
Side Glue Sensor
The side glue sensor is a proximity sensor. This glue sensor is used to
trigger side glue gun activation once the trailing edge of a sheet has passed.
A.6e
Folder Encoder
The folder encoder is connected to the folder shaft. The encoder sends the
CPU 60 pulses for each revolution of the shaft. The CPU calculates the
speed at which the M-40 folder is operating.
A.6f
Discharge Sensor
The discharge sensor is a proximity sensor. It is used to sense folded sheets
leaving the folder and being placed onto the stacking conveyor. If the sensor
is covered for too long, a “DSCH JAM” alarm is declared.
A.6g
Flap Glue Sensors
The flap glue sensors are proximity sensors. These glue sensors are used to
trigger flap glue gun activation once the leading edge of a sheet is detected
The sensor is located in the #1 buckle plate and/or #2 buckle plate,
depending on application.
