Abstract

Abstract A conveyor path comprising three conveyors, namely, a first conveyor disposed at the delivery point, a second conveyor disposed on the build-up stretch, and a third conveyor disposed at the outlet or pick-up point; and further comprising a driving mechanism which enables the second conveyor to be driven independently of the two other conveyors in backward direction, or in conjunction with one of the other conveyors, or both of them, in forward direction; the driving mechanism controlled by a switching arrangement actuated by the passing goods so that, during delivery, the goods accumulate or "build-up" at the beginning of the build-up stretch and, during the release of goods, the goods accumulate at the end of the build-up stretch. In the case of alternating delivery-release operation with an incompletely occupied build-up section, all the goods accumulated at the end of the build-up stretch are shifted to the beginning of the build-up stretch when the delivery station is occupied, whereas the goods present in the above configuration are shifted to the end of the build-up stretch when the pick-up station has been cleared of goods.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 286 words
Conveyor apparatus for parcelled goods, particularly for goods to be stored on pallets, with at least one conveyor path comprising a delivery station, a build-up stretch with a plurality of storage points to be passed in succession by the goods, and a pick-up station, comprising: a first conveyor at the delivery station; a second conveyor along the build-up stretch; a third conveyor at the pick-up station said second conveyor having a beginning adjacent said first conveyor and an end adjacent said third conveyor; driving means for moving said second conveyor independently of said other two conveyors in backward direction or together with either one of said other conveyors or both of them in forward direction; and switching means for controlling said driving means and actuated by the passing goods so that, in a delivery mode, said goods are delivered by said first conveyor to accumulate at the beginning of said build-up stretch and, in a pick-up mode, said accumulated goods are moved to the end of said build-up stretch to be picked up by said third conveyor, and so that, in an alternating delivery and pick-up mode with an incompletely occupied build-up stretch, the totality of goods accumulated at the end of said build-up stretch are shifted backward to the beginning of said build-up stretch when said delivery station is served with goods awaiting to be delivered to said second conveyor, while said totality of goods are shifted to said end of said build-up stretch when said pick-up station is ready to pick up goods from said second conveyor, the shift to the beginning having priority so long as goods are awaiting delivery at said delivery station to an available storage point on said second conveyor.
Claim 2
Dependent Claim 286 words
Conveyor apparatus for parcelled goods, particularly for goods to be stored on pallets, with at least one conveyor path comprising a delivery station, a build-up stretch with a plurality of storage points to be passed in succession by the goods, and a pick-up station, comprising: a first conveyor at the delivery station; a second conveyor along the build-up stretch; a third conveyor at the pick-up station said second conveyor having a beginning adjacent said first conveyor and an end adjacent said third conveyor; driving means for moving said second conveyor independently of said other two conveyors in backward direction or together with either one of said other conveyors or both of them in forward direction; and switching means for controlling said driving means and actuated by the passing goods so that, in a delivery mode, said goods are delivered by said first conveyor to accumulate at the beginning of said build-up stretch and, in a pick-up mode, said accumulated goods are moved to the end of said build-up stretch to be picked up by said third conveyor, and so that, in an alternating delivery and pick-up mode with an incompletely occupied build-up stretch, the totality of goods accumulated at the end of said build-up stretch are shifted backward to the beginning of said build-up stretch when said delivery station is served with goods awaiting to be delivered to said second conveyor, while said totality of goods are shifted to said end of said build-up stretch when said pick-up station is ready to pick up goods from said second conveyor, the shift to the beginning having priority so long as goods are awaiting delivery at said delivery station to an available storage point on said second conveyor.
Claim 3
Dependent Claim 44 words
Conveyor apparatus as defined in claim 1, characterized in that there is provided for said three conveyors a common driving motor which is directly coupled to said second conveyor and coupled to said first and said third conveyor by means of respective clutch couplings.
Claim 4
Dependent Claim 24 words
Conveyor apparatus as defined in claim 2, characterized in that an overrunning clutch is inserted in the driving coupling means to said first conveyor.
Claim 5
Dependent Claim 57 words
Conveyor apparatus as defined in claim 1, characterized in that said switching means comprises a first switching device disposed at the end of said first conveyor, second and third switching devices disposed at the beginning and at the end of said second conveyor, respectively, and a fourth switching device disposed at the end of said third conveyor.
Claim 6
Dependent Claim 66 words
Conveyor apparatus as defined in claim 1, characterized in that the motion of said second conveyor covered with said goods is stepwise during delivery operations of goods and removal of the same, and that said motion is continuous in alternating delivery and pick-up operations when the goods are shifted from the beginning to the end and from the end to the beginning of said build-up stretch.
Claim 7
Dependent Claim 53 words
Conveyor apparatus as defined in claim 1, characterized in that at said delivery station and/or at said pick-up station there is provided more than one storage position and that said first and said third conveyor are subdivided to form a plurality of individually controlled conveyors corresponding to the number of said storage positions.
