Abstract
Abstract In an automatic operation, slide frames or slide frame halves discharged from an injection molding machine are severed and threaded on handling and centering rods, by which the frames or frame halves can be fed in an ordered arrangement to a welding or mounting machine. A receiving hopper is disposed under the point where the frames or frame halves are ejected from the injection molding machine. A guideway leads from the hopper to a severing device, which is disposed on a lower level and into which the handling and centering rods can be inserted.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
Apparatus for the automatic separating and alignment of a plurality of frames which are connected together by a sprue and have been made on an injection molding machine, comprising a receiving hopper, a guide adjoining the receiving hopper and a separating and stacking device arranged at the end of the guide, the separating and stacking device comprising a housing having a plurality of detachably secured transport and centering bars mounted longitudinally therein with the transport bars being positioned behind the centering bars, a cutting knife and a transport pusher are positioned in the housing, the transport pusher being displaceable axially with respect to the transport and centering bars and with respect to the cutting knife, and provided with means to push the frames against the cutting knife and onto the transport and centering bars.
Claim 2
Dependent Claim
134 words
Apparatus for the automatic separating and alignment of a plurality of frames which are connected together by a sprue and have been made on an injection molding machine, comprising a receiving hopper, a guide adjoining the receiving hopper and a separating and stacking device arranged at the end of the guide, the separating and stacking device comprising a housing having a plurality of detachably secured transport and centering bars mounted longitudinally therein with the transport bars being positioned behind the centering bars, a cutting knife and a transport pusher are positioned in the housing, the transport pusher being displaceable axially with respect to the transport and centering bars and with respect to the cutting knife, and provided with means to push the frames against the cutting knife and onto the transport and centering bars.
Claim 3
Dependent Claim
82 words
Apparatus according to claim 1, wherein the housing surrounds and guides the outside of the sprue-connected frames which are carried by the guide into the housing through an aperture in a wall of the housing, the sprue-connected frames rest in the housing and are bounded by the inner surface of the housing walls which serve to center the frames, the transport pusher and the cutting knife which is positioned opposite the transport pusher, the cutting knife being mounted between the centering bars.
Claim 4
Dependent Claim
42 words
Apparatus according to claim 2, wherein the centering bars cooperate with the housing to center the frames, said centering bars being arranged inside the housing and in a position corresponding to the distance between the two adjacent side edges of adjacent frames.
Claim 5
Dependent Claim
65 words
Apparatus according to claim 2, wherein the cutting knife is of substantially circular configuration and the transport pusher comprises a hollow cylinder having an inside diameter which is larger than the outside diameter of the cutting knife, said cylinder having an outlet opening in its body facing away from the cutting knife for discharge of the sprue when it has been cut from the frames.
Claim 6
Dependent Claim
52 words
Apparatus according to claim 4, wherein the transport pusher has a pressure plate mounted on its end facing the cutting knife, said pressure plate having a shape which substantially corresponds to the sprue-connected frames and having openings corresponding to the centering bars and to the cylindrical inside diameter of the transport bars.
Claim 7
Dependent Claim
66 words
Apparatus according to claim 2, wherein the centering bars are beveled in a direction towards the transport pusher and have pressing springs extending in their longitudinal direction, said springs preventing the frames from falling back into the housing when the frames are engaged by the transport pusher, causing the frames to be centered, cut off from the sprue, and stacked surrounding the transport and centering bars.
