Abstract
Abstract A universal head for a drop type case packer, for enabling the packer to handle a range of article sizes and arrays. Lane dividers mounted from the head define parallel lanes, the number, spacing and effective length of which can be set for desired packing conditions. Flags for signaling filling of the lanes are mounted to an adjustable end plate, and can be centered laterally according to lane width and article shape. The flags intercept a light beam between a light emitter and sensor, the alignment of which is maintained regardless of changes in lane number or dimensions. A universal intermediate grid is also provided, having article guide flaps which can be positioned longitudinally to accommodate various arrays and sizes. The flaps are mounted diagonally with respect to transversely positionable bars, and cross bars are obviated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
220 words
A head for an automatic case packer, comprising, a head frame and means for mounting it to the packer, a series of lane dividers mounted from the frame, the dividers providing a plurality of parallel lanes between them for receiving articles in single file relation, an end plate mounted from the frame and extending transversely across the lanes, the end plate presenting a barrier which limits the length of each lane, said end plate carrying a plurality of movable flags projecting into the respective lanes, each flag being positioned for engagement by an article in its lane when the article is proximate to the end plate, at least some of the said flags being mounted from the end plate by means for shifting them in a direction transverse to their respective lanes, in order to be aligned with the respective central planes of a particular size of article to be received in the lanes, each lane divider having a vertical base wall with legs upstanding from the base wall, the divider being suspended from the frame by the legs, said end plate extending transversely across the lanes above the base walls of the respective lane dividers, said end plate having lane stops mounted to it which project downwardly into the respective lanes between the base walls of the lane dividers.
Claim 2
Dependent Claim
220 words
A head for an automatic case packer, comprising, a head frame and means for mounting it to the packer, a series of lane dividers mounted from the frame, the dividers providing a plurality of parallel lanes between them for receiving articles in single file relation, an end plate mounted from the frame and extending transversely across the lanes, the end plate presenting a barrier which limits the length of each lane, said end plate carrying a plurality of movable flags projecting into the respective lanes, each flag being positioned for engagement by an article in its lane when the article is proximate to the end plate, at least some of the said flags being mounted from the end plate by means for shifting them in a direction transverse to their respective lanes, in order to be aligned with the respective central planes of a particular size of article to be received in the lanes, each lane divider having a vertical base wall with legs upstanding from the base wall, the divider being suspended from the frame by the legs, said end plate extending transversely across the lanes above the base walls of the respective lane dividers, said end plate having lane stops mounted to it which project downwardly into the respective lanes between the base walls of the lane dividers.
Claim 3
Dependent Claim
47 words
The head of claim 1 further wherein said lane stops are shiftable with respect to the end plate, in the direction transverse to the lanes, and means for securing the respective lane stops to the end plate in different desired positions, to correspond with different lane spacings.
Claim 4
Dependent Claim
32 words
The head of claim 1 wherein said flags are swingably mounted to said lane stops, the flags being shifted transversely with respect to the lanes as their respective lane stops are shifted.
Claim 5
Dependent Claim
61 words
The head of claim 1, further wherein said end plate is mounted to the frame for movement in the direction longitudinally of said lanes, a hand screw being connected between the frame and end plate for moving the end plate relative to the frame to a desired longitudinal position in said lanes, thereby to set the effective length of the lanes.
Claim 6
Dependent Claim
42 words
The head of claim 1, wherein the said flags are carried by the respective stops and are pivotally mounted thereon, at least some of the respective stops being carried by the end plate for shifting movement with respect to the end plate.
Claim 7
Dependent Claim
156 words
An intermediate grid for a case packer, comprising, a frame having side and end members, a plurality of parallel bars between the end members, means connecting said bars to the end members, the said means being adjustably positionable for shifting the positions at which the bars are connected to the end members thereby to change the spacing between the bars, each bar carrying a plurality of holders each mounting a guide flap, the holders being slidable along the bars for longitudinally positioning the guide flaps thereon, each said holder comprising, a post slidably engaging the bar, the post projecting vertically with respect to the bar, a body mounted to the post, means positioning the guide flap on the body so that the flap projects from the body diagonally to the bar, means for clamping the flap to the body, means for securing the body to the post, and means for clamping the post to the bar.
Claim 8
Dependent Claim
156 words
An intermediate grid for a case packer, comprising, a frame having side and end members, a plurality of parallel bars between the end members, means connecting said bars to the end members, the said means being adjustably positionable for shifting the positions at which the bars are connected to the end members thereby to change the spacing between the bars, each bar carrying a plurality of holders each mounting a guide flap, the holders being slidable along the bars for longitudinally positioning the guide flaps thereon, each said holder comprising, a post slidably engaging the bar, the post projecting vertically with respect to the bar, a body mounted to the post, means positioning the guide flap on the body so that the flap projects from the body diagonally to the bar, means for clamping the flap to the body, means for securing the body to the post, and means for clamping the post to the bar.
Claim 9
Dependent Claim
49 words
The grid of claim 6 wherein the said post presents a diametral slot, said bar extending through said slot, and said means for clamping the post to the bar comprise a surface on said body which bears frictionally on the bar when the body is secured to the post.
Claim 10
Dependent Claim
31 words
The grid of claim 6 wherein the means positioning the guide flap on the body comprise a cross groove in the body in which a portion of the flap is seated.
Claim 11
Dependent Claim
80 words
The grid of claim 6 further wherein each said end member has a groove extending along its length, the means connecting said bars to the said end members each have a boss engaged in the groove of the corresponding end member, the grid further including means securing an end portion of each bar to the respective connecting means, and means for locking the connecting means in desired position along the end member to provide a desired spacing between adjacent bars.
Claim 12
Dependent Claim
36 words
The grid of claim 6 wherein the bars are removably connected to the end members by the connecting means so that bars may be removed and so that additional holders can be slid onto said bars.
