Abstract
Abstract A pallet stocker for a printer in which the pallets, containing film for printing are stacked in a column in pallet supports. To access a given pallet, the higher pallet supports are raised out of the way and the remaining pallets are raised so that a suction arm can remove the top exposed pallet from a fixed level.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
A pallet stocker system, comprising: a pallet stocker for storing a plurality of pallets piled in a stack, said pallets being used to store sheets and having first pawl members; and means for transferring said sheets from selected ones of said pallets in said pallet stocker and to selected ones of said pallets in said pallet stocker, said transferring of said sheets to and from said pallet being performed with a vertical motion of said transferred sheets separating from or coming into contact with said pallets; said pallet stocker comprising a pallet support mechanism for supporting in said stack said plurality of pallets, and a pallet carrier mechanism for vertically moving a selected one of any of said plurality of pallets, thereby moving all of said pallets above said selected pallet in said stack, said pallet carrier mechanism including a chain having a second pawl member selectively engagable with one of said first pawl members and further comprising driving means for driving said chain in opposite vertical directions.
Claim 2
Dependent Claim
168 words
A pallet stocker system, comprising: a pallet stocker for storing a plurality of pallets piled in a stack, said pallets being used to store sheets and having first pawl members; and means for transferring said sheets from selected ones of said pallets in said pallet stocker and to selected ones of said pallets in said pallet stocker, said transferring of said sheets to and from said pallet being performed with a vertical motion of said transferred sheets separating from or coming into contact with said pallets; said pallet stocker comprising a pallet support mechanism for supporting in said stack said plurality of pallets, and a pallet carrier mechanism for vertically moving a selected one of any of said plurality of pallets, thereby moving all of said pallets above said selected pallet in said stack, said pallet carrier mechanism including a chain having a second pawl member selectively engagable with one of said first pawl members and further comprising driving means for driving said chain in opposite vertical directions.
Claim 3
Dependent Claim
26 words
A pallet stocker system as recited in claim 1, wherein said pallet support mechanism supports said stack of said plurality of pallets to a controllable height.
Claim 4
Dependent Claim
51 words
A pallet stocker system as recited in claim 1, further comprising pallet carrier control means for causing said pallet carrier mechanism to simultaneously raise a selected subgroup of said plurality of pallets to a raised position wherein at least one pallet of said selected subgroup is raised to a predetermined position.
Claim 5
Dependent Claim
26 words
A pallet stocker system as recited in claim 3, wherein said pallet support mechanism supports said stack of said plurality of pallets to a controllable height.
Claim 6
Dependent Claim
28 words
A pallet stocker system as recited in claim 4, wherein said pallet support mechanism includes a vertical column on which said pallets are vertically movable and horizontally fixed.
Claim 7
Dependent Claim
61 words
A pallet stocker system as recited in claim 1, wherein said pallet carrier mechanism vertically moves said selected pallet upward by a first distance thereby moving all said pallets above said selected pallet upward by said first distance and opening a gap of said first distance between said selected pallet and an uppermost one of said pallets below said selected pallet.
Claim 8
Dependent Claim
22 words
A pallet stocker system as recited in claim 6, wherein said transferring means operates within at least a portion of said gap.
Claim 9
Dependent Claim
245 words
A pallet stocker system, comprising: a pallet stocker for storing a plurality of pallets piled in a stack, said pallets having first pawl members and being used to store sheets; and means for transferring said sheets from selected ones of said pallets in said pallet stocker and to selected ones of said pallets in said pallet stocker, said transferring of said sheets to and from said pallet being performed with a vertical motion of said transferred sheets separating from or coming into a contact with said pallets; said pallet stocker comprising a pallet support mechanism for supporting in said stack said plurality of pallets, wherein said pallet support mechanism supports said stack of said plurality of pallets to a controllable height which includes a vertical column on which said pallets are vertically moveable and horizontally fixed and a pallet carrier mechanism for vertically moving a selected one of said plurality of pallets, thereby moving all of said pallets above said selected pallet in said stack, said pallet carrier mechanism including a chain having a second pawl member selectively engagable with one of said first pawl members and further comprising driving means for driving said chain in opposite vertical directions; said pallet stocker system further comprising pallet carrier control means for causing said pallet carrier mechanism to simultaneously raise a selected subgroup of said plurality of pallets to a selected position wherein at least one pallet of said selected subgroup is raised to a predetermined position.
Claim 10
Dependent Claim
245 words
A pallet stocker system, comprising: a pallet stocker for storing a plurality of pallets piled in a stack, said pallets having first pawl members and being used to store sheets; and means for transferring said sheets from selected ones of said pallets in said pallet stocker and to selected ones of said pallets in said pallet stocker, said transferring of said sheets to and from said pallet being performed with a vertical motion of said transferred sheets separating from or coming into a contact with said pallets; said pallet stocker comprising a pallet support mechanism for supporting in said stack said plurality of pallets, wherein said pallet support mechanism supports said stack of said plurality of pallets to a controllable height which includes a vertical column on which said pallets are vertically moveable and horizontally fixed and a pallet carrier mechanism for vertically moving a selected one of said plurality of pallets, thereby moving all of said pallets above said selected pallet in said stack, said pallet carrier mechanism including a chain having a second pawl member selectively engagable with one of said first pawl members and further comprising driving means for driving said chain in opposite vertical directions; said pallet stocker system further comprising pallet carrier control means for causing said pallet carrier mechanism to simultaneously raise a selected subgroup of said plurality of pallets to a selected position wherein at least one pallet of said selected subgroup is raised to a predetermined position.
