Abstract
Abstract This invention relates to a magazine for wares for use in automatic shops, comprising a shaft for receiving a pile of packages, wherein there are distributed along the shaft a number of suction cups for retaining the packages individually in the shaft without the packages being in contact with each other, and wherein the suction cups are individually controllable in order to be made inoperative temporarily during a short interval one at a time in a sequence beginning from below and continuing upwards.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A magazine for wares for use in automatic shops, comprising a shaft for receiving a pile of packages, wherein there are distributed along the shaft a plurality of suction means for retaining the packages individually in the shaft without the packages being in contact with each other, said suction means being individually controllable in order to be made inoperative temporarily during a short interval one at a time in sequence beginning from below and continuing upwards, said suction means being connected to a suction line, via a solenoid valve, said solenoid valves being connected to a programming means in order to be closed, resulting in making the suction means inoperative in the indicated sequence, and each said suction means being provided with a sensing member entering the shaft in order to make the suction means operative as a result of a package hitting the sensing member when the package is located opposite the pertinent suction member.
Claim 2
Dependent Claim
156 words
A magazine for wares for use in automatic shops, comprising a shaft for receiving a pile of packages, wherein there are distributed along the shaft a plurality of suction means for retaining the packages individually in the shaft without the packages being in contact with each other, said suction means being individually controllable in order to be made inoperative temporarily during a short interval one at a time in sequence beginning from below and continuing upwards, said suction means being connected to a suction line, via a solenoid valve, said solenoid valves being connected to a programming means in order to be closed, resulting in making the suction means inoperative in the indicated sequence, and each said suction means being provided with a sensing member entering the shaft in order to make the suction means operative as a result of a package hitting the sensing member when the package is located opposite the pertinent suction member.
Claim 3
Dependent Claim
46 words
A magazine as claimed in claim 1, wherein each said suction member contains a valve which can be opened as a result of a package hitting the sensing member, in order to make the suction member operative when the solenoid valve is in an open position.
Claim 4
Dependent Claim
45 words
A magazine as claimed in claim 2, wherein each said suction means includes a bellows, one end of which is shaped as a suction cup opening into the shaft and the other end of which is connected to the suction line via the solenoid valve.
Claim 5
Dependent Claim
48 words
A magazine as claimed in claim 3, wherein disposed in the bellows between its ends is a disc valve controllable by said sensing member and being operable to a closed position as a result of a pressure difference between the bellows ends when the solenoid valve is open.
Claim 6
Dependent Claim
23 words
A magazine as claimed in claim 4, wherein said disc valve is resettable to an open position by actuation of the sensing member.
