US4432686A — Apparatus for placing packets of tube sections in…

Claim 1

Independent Claim 146 words

Apparatus for placing packets of tube sections in the stacking magazine of a rotary applicator equipped with suction rollers, characterised in that, between the stacking magazine and the conveyor means supplying the tube section packets, there is a pivotably mounted arm on which a supporting frame is longitudinally displaceable, the frame being provided at the ends with direction-changing rollers over which endless belts run and being pivotable by a pivot drive between its upper, obliquely rising position in which it receives the tube section packets and its lowered position in which it discharges them again, and that the arm is provided with an abutment securing the tube section packets on the supporting frame and with braking means which engage the upper run of the belts between the abutment and the rear direction-changing roller and which comprise means for releasing same to receive the tube section packets.

Claim 2

Dependent Claim 146 words

Apparatus for placing packets of tube sections in the stacking magazine of a rotary applicator equipped with suction rollers, characterised in that, between the stacking magazine and the conveyor means supplying the tube section packets, there is a pivotably mounted arm on which a supporting frame is longitudinally displaceable, the frame being provided at the ends with direction-changing rollers over which endless belts run and being pivotable by a pivot drive between its upper, obliquely rising position in which it receives the tube section packets and its lowered position in which it discharges them again, and that the arm is provided with an abutment securing the tube section packets on the supporting frame and with braking means which engage the upper run of the belts between the abutment and the rear direction-changing roller and which comprise means for releasing same to receive the tube section packets.

Claim 3

Dependent Claim 45 words

Apparatus according to claim 1, characterised in that the braking apparatus comprises a plate which is disposed below the upper run of the belts and on which, at flanges projecting beyond the belts, there are spring-influenced brake levers which push the belts against the plate.

Claim 4

Dependent Claim 32 words

Apparatus according to claim 2, characterised in that the brake levers have two arms and co-operate with a fixed abutment to release the belts in the raised position of the supporting frame.

Claim 5

Dependent Claim 21 words

Apparatus according to claim 1, characterised in that the arm is provided with a piston-cylinder unit for displacing the supporting frame.

Claim 6

Dependent Claim 24 words

Apparatus according to claim 1, characterised in that the supporting frame is secured to a carriage running on the arm by way of rollers.

Claim 7

Dependent Claim 40 words

Apparatus according to claim 1, characterised in that for the purpose of transferring the tube section packets from supply conveyor means to the belts there is a pivotable roller track which is displaceable in the direction of its pivot shaft.

Claim 8

Dependent Claim 39 words

Apparatus according to claim 1, characterised in that, in its raised position, the pivot frame adjoins conveyor means with the belts, the conveyor means being provided with a push member for pushing the tube section packets onto the belts.

Claim 9

Dependent Claim 64 words

Apparatus according to claim 1, characterised in that the arm is pivoted to a pivot lever pivoted to the machine frame and a linkage is provided which consists of rods and levers and, in the raised position of the pivot lever, swings the arm downwardly relatively thereto and, in the lowered position, is adapted to the position of the stack located in the magazine.

Claim 10

Dependent Claim 32 words

Apparatus, particularly according to claim 1, characterised in that pivotably mounted conveyor means are provided for transferring the stacks from the supply conveyor means to the supporting frames provided with the belts.

Claim 11

Dependent Claim 31 words

Apparatus according to claim 9, characterised in that the conveyor means are provided in the region of the pivot shaft with an abutment which upstands perpendicular thereon and extends transversely thereto.

Claim 12

Dependent Claim 15 words

Apparatus according to claim 9 characterised in that the conveyor means comprise a roller track.

Claim 13

Dependent Claim 19 words

Apparatus according to claim 9 characterised in that the conveyor means comprise a belt conveyor equipped with a drive.

Claim 14

Dependent Claim 127 words

Apparatus for placing packets of tube sections in the stacking magazine of a rotary applicator equipped with suction rollers, said apparatus comprising: an arm pivotably mounted to the rotary applicator; a supporting frame longitudinally displaceable on said arm; a plurality of endless belts; said frame being provided with a first and a second direction-changing roller over which said endless belts run; a pivot drive for moving said frame between an upper, obliquely rising position in which said frame receives the packets of tube sections and a lowered position in which said frame discharges the tube section packets; and braking means for engaging said belts at said lowered position of said frame and during the descent of said frame from said upper position until reaching said lowered position.

Claim 15

Dependent Claim 127 words

Apparatus for placing packets of tube sections in the stacking magazine of a rotary applicator equipped with suction rollers, said apparatus comprising: an arm pivotably mounted to the rotary applicator; a supporting frame longitudinally displaceable on said arm; a plurality of endless belts; said frame being provided with a first and a second direction-changing roller over which said endless belts run; a pivot drive for moving said frame between an upper, obliquely rising position in which said frame receives the packets of tube sections and a lowered position in which said frame discharges the tube section packets; and braking means for engaging said belts at said lowered position of said frame and during the descent of said frame from said upper position until reaching said lowered position.

Claim 16

Dependent Claim 19 words

Apparatus according to claim 13, wherein said arm is provided with a piston-cylinder unit for displacing said supporting frame.

Claim 17

Dependent Claim 42 words

Apparatus according to claim 14, characterised in that, in said raised position, said belts of said frame are adjacent to a conveyor means, said conveyor means being provided with a push member for pushing the packets of tube sections onto said belts.

Claim 18

Dependent Claim 34 words

Apparatus according to claim 13, wherein said braking means comprise a clutch means connecting the second direction-changing roller to a gear, and said gear is in mesh with a rack connected to said arm.

Claim 19

Dependent Claim 13 words

Apparatus according to claim 16, wherein said rack is hinged to said arm.
