Description
Preparing products for infeed to the machine
/i
The product is fed in onto the supply conveyor
and monitored by sensor S1. The sensor is
located on the end of the supply conveyor. The
product (A) will wait at this position until the
product release sensor B1 (not shown in this
figure) sends a release signal to infeed the
product to the machine. Refer to sensor B7 as
shown in the illustration at the start of section
4.2. Products are supplied to the machine only
when this release signal has been sent.
If a product backup occurs, the release to the infeed signal must be stopped to make sure
further products are not infed to the machine. It is still possible to discharge products that
are still in the machine.
Monitoring products supplied to the infeed/outfeed conveyor
When a product has come off the supply conveyor this is detected by sensor S1. The
transport to the infeed conveyor must stop. Sensor B7 detects the product when it is far
enough onto the infeed conveyor. The infeed conveyor must also be stopped.
The transporter empty photocell monitors run-time. The run-time function checks to make
sure a product does not take too long to move from the supply conveyor to the infeed
conveyor.
Product release sensor
The product release sensor B1 is operated by
each product carrier of the machine in the
circular movement, after which a time frame is
started. At the moment that this time frame is
active, the infeed position is free and there is
time to feed in a product to the infeed position.
This sensor must be mounted to the machine
frame. The sensor must be set so that it is
activated when the product carrier is just
above the highest product at the infeed
position. The time frame (set by software) must
be long enough for feeding in the product at
the utmost time without having to stop the
machine. This implies that this time depends
on the circulation speed of the product carriers
and on the infeed speed of the product. This time frame must be set during the test phase.
