Abstract

Abstract This relates to a transfer apparatus for transferring labels from a label stack into the cavity of a moving mold half. The transfer device includes a pivotally mounted arm which has mounted on its free end a transfer head which swings about the arm so that for a limited movement of the arm there can be a much greater movement of the transfer head. Thus, the transfer head may rapidly enter and rapidly depart from a mold cavity so that a label may be seated in the mold cavity very quickly without requiring any slowdown of the movement of the mold half. The transfer head is provided with vacuum heads which operate to effect a peeling of a label from its associated stack beginning along one edge portion of the label so as to assure that only a single label is picked up from the stack.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 177 words
A transfer device for transferring a label or like sheet from a stack to a moving member, said transfer device comprising a pivotally mounted arm, a transfer head pivotally mounted on said arm remote from its pivot and for pivoting with said arm and relative to said arm, said transfer head having transfer means for picking up and discharging labels and like sheets, return means coupled to said arm for positioning said arm and said transfer head with said transfer head being disposed adjacent said stack of sheets, drive means coupled to said arm for overcoming said return means and pivoting said arm and said return means in a selected direction to a position to deposit a transferred sheet on said moving member in response to movement of said moving member relative to said transfer device, and actuator means for pivoting said transfer head relative to said arm in said selected direction in response to pivoting of said arm whereby the total pivoting of said transfer head is greatly in excess of the pivoting of said arm.
Claim 2
Dependent Claim 177 words
A transfer device for transferring a label or like sheet from a stack to a moving member, said transfer device comprising a pivotally mounted arm, a transfer head pivotally mounted on said arm remote from its pivot and for pivoting with said arm and relative to said arm, said transfer head having transfer means for picking up and discharging labels and like sheets, return means coupled to said arm for positioning said arm and said transfer head with said transfer head being disposed adjacent said stack of sheets, drive means coupled to said arm for overcoming said return means and pivoting said arm and said return means in a selected direction to a position to deposit a transferred sheet on said moving member in response to movement of said moving member relative to said transfer device, and actuator means for pivoting said transfer head relative to said arm in said selected direction in response to pivoting of said arm whereby the total pivoting of said transfer head is greatly in excess of the pivoting of said arm.
Claim 3
Dependent Claim 53 words
A transfer device according to claim 1 wherein said actuator means includes a slide member on said arm, a link extending between said slide member and said transfer head, and a cam and cam follower for effecting controlled sliding of said slide member on said arm in response to pivoting of said arm.
Claim 4
Dependent Claim 22 words
A transfer device according to claim 2 wherein said cam is fixed and said cam follower is carried by said slide member.
Claim 5
Dependent Claim 34 words
A transfer device according to claim 3 wherein said cam follower is carried by a pin extending through a slot in said arm and serving as means retaining said slide member on said arm.
Claim 6
Dependent Claim 17 words
A transfer device according to claim 4 wherein said pin also forms a pivot for said link.
Claim 7
Dependent Claim 40 words
A transfer device according to claim 1 wherein said drive means includes a drive member, a link connecting said drive member to said arm, and a movable cam connected to said drive member for effecting reciprocation of said drive member.
Claim 8
Dependent Claim 30 words
A transfer device according to claim 6 wherein said link is pivotally mounted for pivoting about a fixed axis and has sliding connections with said arm and said drive member.
Claim 9
Dependent Claim 54 words
A transfer device according to claim 6 wherein said return means includes said cam being spring urged to a normal position, and said cam having an exit portion with a projection for effecting momentary movement of said transfer head towards a stack beyond the normal position of said transfer means relative to a stack.
Claim 10
Dependent Claim 70 words
A transfer device according to claim 6 wherein said transfer head includes suction heads for engaging and holding a sheet to be transferred, suction means and pressure means for coupling to said suction heads to selectively hold a sheet and discharge a sheet, and control means for said suction means and said pressure means coupled to said drive member for actuation in accordance with the position of said drive member.
Claim 11
Dependent Claim 78 words
A transfer device according to claim 1 wherein said transfer device is part of a rotary blow molding machine having a horizontal axis of rotation and wherein blow mold halves of said machine are separated in a radial direction, the moving member is at least one of said blow mold halves, said blow mold halves have recessed cavities, and said transfer head is movable into a cavity of a respective moving blow mold half to deposit a label.
Claim 12
Dependent Claim 58 words
A transfer device according to claim 1 wherein the stacked position of a sheet is angularly remote from its intended position on a moving member on the order of 270°, said arm pivots through an arc on the order of 110°, and said transfer head pivots relative to said arm through an arc on the order of 160°.
