Safety Support Device “CLAMP SENSOR” : Prevention of finger injury during pedal clamp operation.

Safety Support Device : CLAMP SENSOR
Prevention of finger injury during pedal clamp operation.

For the cutting position checking operation, usually it is checked by foot pedal clamp.
To prevent injury by clamp during such operation, "Soft Clamp function" already introduced and some cutting machine has been prepered.
The "Soft Clamp Function" is restrict pedal clamp pressure to be 20kg, so even if the finger ( for example) touched during its operation.
So that it is expected finger is not injury by touching clamp.
But, Operator feels very hard if their finger touched clamp.
This "Clamp Sensor" Safety support function is to prevent such touching.
The Sensors beam at the bottom of clamp detects fingers ( or something) , then clamp stop and move up even if pedal has been footed.
Operator will feel more safety.
( Patent pending)

Clamp Accident Problem

Until now, I think that measures have been taken to prevent accidents, such as attaching a cover to the pedal or using a safety auxiliary device such as a soft clamp to reduce the pedal pressure of the clamp. However, isn't the accident recurring and burdening the cutting operator without taking measures to prevent the accident in a nearly complete state? Therefore, we will propose the "clamp sensor" this time.

Avoid Accidents Before Happen !!

The clamp sensor is a safety device that immediately raises the clamp gauge when four sets of sensors installed below the clamp gauge detect fingers or foreign matter other than the work. You can avoid accidents that you accidentally pinch your fingers or foreign matter placed on the work. By installing the clamp sensor, you can adjust the cutting position with peace of mind.

・When the workpieces are stacked low (Less)
When the clamp operation is in a wide range, the upper and lower sensors work together to detect foreign matter.
・When the workpieces are piled up (Many)
In a narrow clamp range, only the upper sensor works and detects foreign matter. 
It is now possible to avoid a clamp accident at the time of the day, which was difficult to prevent by any means, without touching the clamp. In the case of conventional soft clamps, even though the clamps are soft, the clamps were supposed to pinch a finger or the like, so even if the degree of injury decreased, the operator met with pain. On the other hand, by introducing a clamp sensor, the clamp rises before it hits the finger, so the finger is not even scratched. In addition, even if the work has waviness, curls, swelling of saddle stitch, etc., it can be handled by setting the sensitivity adjustment on the panel. Furthermore, it is possible to set the clamp operating speed in case of register in two steps on the panel. ■The clamp sensor operates within a range of 80 mm if the object is 5 mm or more and 1.5 mm or more behind the clamp edge. In addition, things that allow objects to pass through may not work. For details, see the instruction manual.
■The operation may be delayed depending on the clamp throw setting. For details, see the instruction manual.
■If the knife ring is removed when the knife is replaced, the sensor is blocked by the back gauge, or the sensor setting is turned off, it will not work.
■ The clamp sensor is a safety device. Do not overreliance on this function, and be sure that the operator pays sufficient attention to safety and works responsibly.
