Abstract
Abstract An apparatus for transporting and exchanging containers of textile strand material at a textile strand processing machine having a plurality of processing stations is disclosed. The device includes a guide device for guiding containers around the machine. An endless drive connection reciprocally movable in the transport path and having flexible portions reciprocally movable through the corner sections of the transport path is included as well as a drive means for reciprocally driving the drive connection. Container engaging elements are also provided for drivingly engaging containers during movement of the drive connection. The drive connection may include rods disposed in the straight portions of the transport path which are connected to the flexible portions. The container engaging elements may comprise pawls mounted on transverse shafts which may be spring biased into the container engaging dispositions. The drive may act directly on at least one of the rods, a sprocket located at the corner sections and the flexible portions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
A device for transporting and exchanging containers of textile strand material at a textile strand processing machine having a plurality of processing stations, said device comprising: (a) guide means for guiding containers in a transport path extending around the machine past the processing stations, said transport path having straight sections and corner sections connecting the straight sections; (b) an inserting station at which containers may be inserted into the transport path; (c) a discharging station at which containers may be discharged from the transport path; (d) an endless drive connection reciprocally movable in the transport path and having flexible portions reciprocally movable through the corner sections of the transport path; (e) drive means for reciprocally driving said drive connection for reciprocation in the transport path; and (f) container engaging elements projecting from and at spacings along said drive connection in the straight sections of the transport path for drivingly engaging containers during movement of the drive connection in one direction and out of driving engagement with containers during movement of the drive connection in the opposite direction, thereby step-wise advancing the containers along the transport path.
Claim 2
Independent Claim
186 words
A device for transporting and exchanging containers of textile strand material at a textile strand processing machine having a plurality of processing stations, said device comprising: (a) guide means for guiding containers in a transport path extending around the machine past the processing stations, said transport path having straight sections and corner sections connecting the straight sections; (b) an inserting station at which containers may be inserted into the transport path; (c) a discharging station at which containers may be discharged from the transport path; (d) an endless drive connection reciprocally movable in the transport path and having flexible portions reciprocally movable through the corner sections of the transport path; (e) drive means for reciprocally driving said drive connection for reciprocation in the transport path; and (f) container engaging elements projecting from and at spacings along said drive connection in the straight sections of the transport path for drivingly engaging containers during movement of the drive connection in one direction and out of driving engagement with containers during movement of the drive connection in the opposite direction, thereby step-wise advancing the containers along the transport path.
Claim 3
Dependent Claim
53 words
A device for transporting and exchanging containers according to claim 1 wherein said endless drive connection includes rods disposed in said straight portions of the transport path and connected to said flexible portions, said rods being of a length to remain between said corner sections during reciprocal movement of said endless drive connection.
Claim 4
Dependent Claim
22 words
A device for transporting and exchanging containers according to claim 1 wherein said container engaging elements comprise pawls mounted on transverse shafts.
Claim 5
Dependent Claim
21 words
A device for transporting and exchanging containers according to claim 3 wherein said pawls are spring biased into container engaging dispositions.
Claim 6
Dependent Claim
57 words
A device for transporting and exchanging containers according to claim 4 wherein the containers have bottom rims and said pawls are disposed for engaging the bottom rims during movement of said pawls in one direction and are depressed by the rim to pass thereunder without driving the containers, during movement of said pawls in the other direction.
Claim 7
Dependent Claim
45 words
A device for transporting and exchanging containers according to claim 1 wherein the distance between adjacent container engaging elements on said transport path varies from one said container engaging element to the next said container engaging element for different pairs of said container engaging elements.
Claim 8
Dependent Claim
43 words
A device for transporting and exchanging containers according to claim 6 wherein the distance from one of said container engaging elements to the next said container engaging element on said transport path is adapted to requirements at each respective position of the machine.
Claim 9
Dependent Claim
30 words
A device for transporting and exchanging containers according to claim 2 wherein a sprocket is disposed in each corner section and said flexible portions comprise chains trained around said sprockets.
Claim 10
Dependent Claim
27 words
A device for transporting and exchanging containers according to claim 8 wherein said drive means acts directly on at least one of said rods, sprockets and chains.
Claim 11
Dependent Claim
30 words
A device for transporting and exchanging containers according to claim 1 wherein a pulley is disposed in each corner section and said flexible portions comprise belts trained around said pulley.
Claim 12
Dependent Claim
27 words
A device for transporting and exchanging containers according to claim 10 wherein said drive means acts directly on at least one of said rods, pulleys and belts.
