Abstract
Abstract An arrangement for inserting utensils or similar small parts in a clamping frame for machining purposes. Adjacent stacks of parts to be machined are held in a magazine. A gripper provided with gripping elements grips simultaneously the upper part in each of the adjacently-lying stacks. The gripper moves downward into the magazine and cooperates with a clamping frame which, when open, takes from the gripper the parts that it picked up.

Claim 1
Independent Claim
239 words
An arrangement for inserting substantially elongated parts to be machined in a clamping frame comprising, in combination, magazine means having adjacently-lying stacks of parts to be machined; gripping means movable downward on said stacks in said magazine means, and having at least one gripping element for gripping simultaneously the upper parts in each stack; a clamping frame with support means cooperating with said gripping means for taking, when open, parts in their longitudinal directions after having been picked up by said gripping means, the uppermost parts in said stack being gripped simultaneously in unison by said gripping means and placed simultaneously in said clamping frame for becoming machined; transfer means between said gripping means and said clamping frame for transferring said parts when said gripping means and said clamping frame are stationary; means for moving said magazine means with respect to said gripping means in a loading position of said magazine means, said magazine means havng a displaceable frontal wall corresponding to the length of said parts; a rotatable platen for supporting at least two magazine means, said gripping means comprising a movable up-and-down member, said gripping means having gripping elements comprising suction heads; a suction pump with control valve means connected to said suction heads; means for displacing and interchanging said suction heads; drive means for automatically closing said clamping means; and means for automatically controlling the motion and sequential operation of at least part of said arrangement.
Claim 2
Dependent Claim

An arrangement for inserting substantially elongated parts to be machined in a clamping frame comprising, in combination, magazine means having adjacently-lying stacks of parts to be machined; gripping means movable downward on said stacks in said magazine means, and having at least one gripping element for gripping simultaneously the upper parts in each stack; a clamping frame with support means cooperating with said gripping means for taking, when open, parts in their longitudinal directions after having been picked up by said gripping means, the uppermost parts in said stack being gripped simultaneously in unison by said gripping means and placed simultaneously in said clamping frame for becoming machined; transfer means between said gripping means and said clamping frame for transferring said parts when said gripping means and said clamping frame are stationary; means for moving said magazine means with respect to said gripping means in a loading position of said magazine means, said magazine means havng a displaceable frontal wall corresponding to the length of said parts; a rotatable platen for supporting at least two magazine means, said gripping means comprising a movable up-and-down member, said gripping means having gripping elements comprising suction heads; a suction pump with control valve means connected to said suction heads; means for displacing and interchanging said suction heads; drive means for automatically closing said clamping means; and means for automatically controlling the motion and sequential operation of at least part of said arrangement.
Claim 3
Dependent Claim
164 words
An arrangement for inserting substantially slim elongated parts, such as cutlery parts, into a clamping frame for machining said parts, comprising, in combination, magazine means for receiving a plurality of stacks of said parts in a side-by-side arrangement with respect to the longitudinal direction of said parts; gripping means movable upwards and downwards on said stacks in said magazine means and having at least one gripping element for gripping and lifting simultaneously in unison the upper parts of each stack; at least on clamping frame for receiving when open the lifted parts in the same side-by-side arrangement as said parts are held by said gripping means, said clamping frame having closure means for closing said clamping frame after receiving said parts; support means for receiving and supporting said clamping frame in predetermined position; and transfer means for transferring the lifted parts horizontally from a position above said stacks within said magazine means to a clamping position within said clamping frame on said support means.
Claim 4
Dependent Claim
164 words
