Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
An apparatus for packaging product-filled sealed bags in an upright position in packing cases comprising: means for arranging a predetermined number of bags in a row; a movable bottom plate capable of supporting at least one row accumulated thereon; means for delivering the row from the arranging means to the bottom plate; means for positioning the row in an upright position on the bottom plate; means for supporting the row on the bottom plate in the upright position by applying a lateral gripping force to opposite sides of the row; means for moving the bottom plate to a non-supporting position after the row has been gripped; and a vertically movable pushing plate operable to push the row in its upright position downwardly into an open, underlying packing case after the bottom plate is moved to its non-supporting position.
Claim 2
Independent Claim
138 words
An apparatus for packaging product-filled sealed bags in an upright position in packing cases comprising: means for arranging a predetermined number of bags in a row; a movable bottom plate capable of supporting at least one row accumulated thereon; means for delivering the row from the arranging means to the bottom plate; means for positioning the row in an upright position on the bottom plate; means for supporting the row on the bottom plate in the upright position by applying a lateral gripping force to opposite sides of the row; means for moving the bottom plate to a non-supporting position after the row has been gripped; and a vertically movable pushing plate operable to push the row in its upright position downwardly into an open, underlying packing case after the bottom plate is moved to its non-supporting position.
Claim 3
Dependent Claim
66 words
An apparatus according to claim 1 wherein the bags are delivered to the arranging means one at a time by a single channel conveyor, the arranging means including an inclined plate onto which the bags are delivered and a power-operated pushing plate extendable along the inclined plate successively to position each bag along the inclined plate to form the row of bags closely adjacent one another.
Claim 4
Dependent Claim
98 words
An apparatus according to claim 1 wherein the arranging means includes an inclined plate onto which the bags are delivered one at a time from a conveyor, the delivering means and positioning means including a common member pivotable from a holding position in which one surface thereof supports the bags on the inclined plate and another surface thereof forms part of the supporting means adapted to support one side of a row on the bottom plate, to a retracted position in which the row formed on the inclined plate is free to slide downwardly onto the bottom plate.
Claim 5
Dependent Claim
77 words
An apparatus according to claim 1 wherein the supporting means includes a power-operated back plate movable in a horizontal direction laterally to support one side of a row on the bottom plate, and means for retracting the back plate incrementally away from the positioning means a distance approximating the thickness of a row when an additional row is positioned on the bottom plate, thereby to maintain a substantially constant gripping force on the accumulated group of rows.
Claim 6
Dependent Claim
81 words
An apparatus according to claim 4 wherein the retracting means comprises a cylinder means mounted at one end to a frame of the apparatus and having at its other end a piston rod attachment resiliently connected to the back plate, and a stop member carried by the attachment which contacts the back plate when the additional row is positioned on the bottom plate, thereby to generate an actuating signal causing the piston rod attachment and connected back plate to be retracted.
Claim 7
Dependent Claim
45 words
An apparatus according to claim 1 wherein the arranging means includes at least one horizontal endless chain provided with vertical carrier plates defining stalls for supporting an upright bag therebetween and a feeding pipe having an opening above the stalls through which bags are fed.
Claim 8
Dependent Claim
80 words
An apparatus according to claim 1 wherein the arranging means includes a plurality of vertical carrier plates defining stalls therebetween, a feeding pipe above the stalls through which bags may be introduced one at a time into a stall, means for moving the feeding pipe and stalls relative to each other to enable a predetermined number of bags to be introduced into adjacent stalls to form a row, and a retractable plate underneath the stalls to support the bags thereon.
