Abstract
A spring (18) is interposed between the sliding carriage (6) carrying a hammer (13) for driving-in and the actuator rod. The spring is mounted on the head (15) of a push rod, which carries a push contact (16) surrounded by an insulating washer (17). A O pad (20) is housed in the central opening of another insulating washer (19) supported by the spring. These detection means are activated when the spring is compressed in response to the stapling effort required at the moment when a staple comes up against the frame mouldings to be assembled. Application in frame-assembling machines.
Claims5
A device for detecting the engagement of a staple, for a frame-assembling machine, comprising a stapling bar accommodating a staple-dispensing head and also a carriage sliding in a vertical direction below said bar along guide columns, and carrying a hammer for driving in the staple, said carriage being moved by a rod of an actuator, wherein a spring is interposed between the sliding carriage and the rod of the actuator;
- and said spring is associated with means for detecting and activates those detecting means in response to the stapling effort required when a staple comes up against the frame moldings to be assembled.
