Abstract
Abstract An apparatus to be used in transferring a bundle of paper from a paper pile on a table lifter or the like onto a table in the subsequent step. Upon detecting undulation in the top surface of the paper pile, a suitable number of detectors emit a signal indicating whether the paper bundle can be transferred or not to control the upward movement of the paper pile. Before transference, the end of the undulated paper bundle is flattened by an intermediate unit and clamped by a clamp device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
An apparatus for transferring a bundle of paper from a paper pile on a table lifter or the like onto a table comprising an automatic detecting means adapted to detect the level of undulation in the top surface of an end portion close to said table of the paper pile and to emit a signal to indicate whether said table lifter should be elevated or not and whether the paper bundle is to be transferred or not so as to control the upward movement of the paper pile, and intermediate paper bundle transfer means adapted to eliminate the undulation in the end portion of the paper bundle and flatten the end portion so as to facilitate clamping by clamp means when the paper bundle is transferred onto said table.
Claim 2
Independent Claim
129 words
An apparatus for transferring a bundle of paper from a paper pile on a table lifter or the like onto a table comprising an automatic detecting means adapted to detect the level of undulation in the top surface of an end portion close to said table of the paper pile and to emit a signal to indicate whether said table lifter should be elevated or not and whether the paper bundle is to be transferred or not so as to control the upward movement of the paper pile, and intermediate paper bundle transfer means adapted to eliminate the undulation in the end portion of the paper bundle and flatten the end portion so as to facilitate clamping by clamp means when the paper bundle is transferred onto said table.
Claim 3
Independent Claim
220 words
An apparatus for automatically detecting the level of a pile of paper to be moved upward by a table lifter or the like provided with a suitable number of detectors positioned above an end portion at the delivery side of a bundle of paper on the paper pile and disposed at least in two suitable positions, each of said detectors comprising an actuating member adapted tO be pushed upward while in contact with the top surface of the paper pile, a primary detecting member adapted to be actuated by said actuating member when the top surface of the paper pile reaches a predetermined level and a secondary detecting member adapted to be actuated by said actuating member when the top surface of the paper pile reaches a predetermined level higher than the actuating level of said primary detecting member, said apparatus being adapted to emit a primary detecting signal to indicate that the paper bundle can be transferred and to stop the upward movement of said table lifter when all of said primary detecting members in said detectors are actuated, said apparatus further being adapted to emit a secondary detecting signal to indicate that the paper bundle cannot be transferred and to stop the upward movement of said table lifter when any one of said secondary detecting members is actuated.
Claim 4
Independent Claim
220 words
An apparatus for automatically detecting the level of a pile of paper to be moved upward by a table lifter or the like provided with a suitable number of detectors positioned above an end portion at the delivery side of a bundle of paper on the paper pile and disposed at least in two suitable positions, each of said detectors comprising an actuating member adapted tO be pushed upward while in contact with the top surface of the paper pile, a primary detecting member adapted to be actuated by said actuating member when the top surface of the paper pile reaches a predetermined level and a secondary detecting member adapted to be actuated by said actuating member when the top surface of the paper pile reaches a predetermined level higher than the actuating level of said primary detecting member, said apparatus being adapted to emit a primary detecting signal to indicate that the paper bundle can be transferred and to stop the upward movement of said table lifter when all of said primary detecting members in said detectors are actuated, said apparatus further being adapted to emit a secondary detecting signal to indicate that the paper bundle cannot be transferred and to stop the upward movement of said table lifter when any one of said secondary detecting members is actuated.
Claim 5
Dependent Claim
75 words
The automatic-detecting apparatus as claimed in claim 2 which is provided with retracting means comprising release levers for pushing up said actuating members of said detectors, a rotatable rod fixedly provided with the same number of said release levers as said detectors and in air cylinder for driving said rotatable rod, said retracting means being adapted to push up said actuating members of said detectors upon generation of either the primary or secondary detecting signals.
Claim 6
Dependent Claim
47 words
The automatic detecting apparatus as claimed in claim 2 which is provided with a horizontal rod adapted to be moved upward or downward by rotating screw rods attached to a main frame and said detectors and retracting means are mounted on said horizontal rod at adjustable positions.
Claim 7
Independent Claim
134 words
An apparatus for intermediately transferring a bundle of paper comprising a vertically movable guide plate for receiving an end portion of the paper bundle, stoppers disposed in upright position in facing relationship with the end face of the paper bundle received on said guide plate and adapted to be moved downward to retract from the path of the paper bundle simultaneously with the upward movement of said guide plate, and a connecting plate interposed between said guide plate and a table and positioned at the same level as said table, said guide plate being provided with recessed portions for receiving clamping members of clamp means, said stoppers being provided with limit switches adapted to elevate said guide plate and to retract said stoppers when brought into contact with the end of the paper bundle.
Claim 8
Independent Claim
134 words
