Abstract
A method and device for feeding blanks on a packing machine, whereby a conveyor feeds along a horizontal path a succession of blanks positioned perpendicular to the path; the path terminating at a pickup station having a stop surface defined by a frame, which has a withdrawal opening closed partly by fixed teeth and is moved in a direction substantially parallel to the path by the thrust exerted by the blanks and in opposition to a sensor for regulating a traveling speed of the conveyor to keep the thrust exerted by the blanks on the frame constant.
Claims7
A device for feeding blanks on a packing machine, the device comprising a pickup station having a stop means;
- a powered conveyor for feeding a succession of said blanks to the pickup station and along a given horizontal path;
- pickup means located at said pickup station to withdraw an end blank contacting said stop means;
- a force sensor connected to said stop means to determine a value of a thrust exerted by said blanks on said stop means;
- and control means connected to said force sensor and to said conveyor to maintain said thrust constant by regulating a traveling speed of said conveyor;
- the device being characterized in that said stop means comprises a stop surface defined by a frame having a withdrawal opening closed partly by fixed teeth;
- said frame being mounted movably in an adjusting direction substantially parallel to said path and in opposition to said force sensor.
