Abstract
Abstract The invention relates to a conveyor provided with a frame and with at least one carrier guided by a guide mechanism, which can be moved in the longitudinal direction of the conveyor by a driving mechanism. At least some of the carriers support sliding pieces, which can be moved with respect to the carriers in question by a control mechanism, in a direction transversely to the intended direction of movement of the carriers during operation, so as to move objects to be transported with the conveyor during operation. The carriers are guided by a single elongated guide mechanism, while a sliding piece is provided with a receptacle which is open at its bottom side. The sliding piece is movable with respect to a carrier(s), between a first position, in which the receptacle is closed by a closing mechanism connected to a carrier(s), and a second position, in which the receptacle in the sliding piece is located beside the closing mechanism and beside the guide mechanism.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
161 words
A conveyor provided with a frame and with at least one carrier guided by a guide means, which can be moved in a longitudinal direction of the conveyor by driving means, whereby at least some of the carriers support sliding pieces, which can be moved with respect to said carriers by control means, in a direction transversely to an intended direction of movement of the carriers during operation, so as to move objects to be transported with the conveyor during operation, wherein said carriers are guided by a single elongated guide means, while a sliding piece is provided with a receptacle, which is open at its bottom side, and is movable with respect to said carriers, between a first position, in which the receptacle is closed by a closing means connected to at least one of said carriers, and a second position, in which said receptacle in the sliding piece is located beside the closing means and beside the guide means.
Claim 2
Dependent Claim
161 words
A conveyor provided with a frame and with at least one carrier guided by a guide means, which can be moved in a longitudinal direction of the conveyor by driving means, whereby at least some of the carriers support sliding pieces, which can be moved with respect to said carriers by control means, in a direction transversely to an intended direction of movement of the carriers during operation, so as to move objects to be transported with the conveyor during operation, wherein said carriers are guided by a single elongated guide means, while a sliding piece is provided with a receptacle, which is open at its bottom side, and is movable with respect to said carriers, between a first position, in which the receptacle is closed by a closing means connected to at least one of said carriers, and a second position, in which said receptacle in the sliding piece is located beside the closing means and beside the guide means.
Claim 3
Dependent Claim
24 words
A conveyor according to claim 1, wherein said sliding piece is movable from said first position to said second position in two opposite directions.
Claim 4
Dependent Claim
129 words
A conveyor provided with a frame and with carriers guided by guide means, which can be moved in a longitudinal direction of the conveyor by driving means, whereby at least some of the carriers support sliding pieces, which can be moved with respect to said carriers by control means, in a direction transversely to an intended direction of movement of the carriers during operation, so as to move objects to be transported with the conveyor during operation, wherein said sliding piece is provided with a receptacle for receiving at least one object, while said sliding piece is movable from a central position in two opposite directions with respect to the carrier, said receptacle comprising interconnecting upstanding wall means which define a space for accommodating said at least one object.
Claim 5
Dependent Claim
129 words
A conveyor provided with a frame and with carriers guided by guide means, which can be moved in a longitudinal direction of the conveyor by driving means, whereby at least some of the carriers support sliding pieces, which can be moved with respect to said carriers by control means, in a direction transversely to an intended direction of movement of the carriers during operation, so as to move objects to be transported with the conveyor during operation, wherein said sliding piece is provided with a receptacle for receiving at least one object, while said sliding piece is movable from a central position in two opposite directions with respect to the carrier, said receptacle comprising interconnecting upstanding wall means which define a space for accommodating said at least one object.
Claim 6
Dependent Claim
30 words
A conveyor according to claim 3, wherein said receptacle of said sliding piece is open at its bottom side and is closed by a closing means in said central position.
Claim 7
Dependent Claim
51 words
A conveyor according to one of claims 1 or 3, wherein said sliding piece co-operates with an at least substantially T-shaped carrier, which is provided with a beam, along which a coupling piece is movable, and with a platform, which closes said receptacle at its bottom side in said first position.
Claim 8
Dependent Claim
50 words
A conveyor according to one of claims 1 or 3, wherein the sliding piece co-operates with an L-shaped carrier, which is provided with a beam, along which a coupling piece connected to said sliding piece is movable, and with a platform, which can close an open bottom of said receptacle.
Claim 9
Dependent Claim
80 words
A conveyor according to one of claims 1 or 3, wherein said carrier supports a bottom plate and said sliding piece, whereby said bottom plate and said sliding piece are movable in opposite directions with respect to each other, from a first position, in which said sliding piece is positioned above the bottom plate closing said sliding piece at its bottom side, to a second position, in which said sliding piece is at least partly positioned beside said bottom plate.
Claim 10
Dependent Claim
25 words
A conveyor according to claim 7, wherein said bottom plate and said sliding piece are each movable from a central position in two opposite directions.
Claim 11
Dependent Claim
