Definitions

the present invention generally relates to the field of paper converting machines and more precisely it relates to an apparatus for conveying the cut portions, such as rolls or stacks, and for removing the trimmed portions in a transversal cutting machine of logs of paper and the like.
the transversal cutting machines have just the object of cutting off into rolls or shorter stacks the logs of paper and comprise normally a bench with one or more slides onto which the logs to cut off are placed in turn.
a stepped conveying system pushes a log portion beyond the cutting line of a rocking saw.
a clamping device holds the log upstream and downstream of the cutting line. Once cut off, the roll or the stack is carried away by a conveying apparatus provided downstream of the cutting zone.
the front and back ends of the log are then trimmed and the trimmed portions are taken away along an outlet conveyor.
the stepped movement of the log is carried out by means of pushers that protrude from a chain, which translates centrally in the slide on which the log lays.
a first problem of the existing machines is that the pushers have a limited surface and in particular are substantially rectangular strips. This shape is due to the limited clearance at the moment of the passage in the zone of conveying away the rolls or stacks. In fact, the removal is normally carried out by means of parallel belts close to one another, whereby the pushers, which are fastened to a loop chain, in the outlet zone have to pass between two belts and then turn back.
the limited surface and the strip-like shape of the pushers have the consequence of a not regular cut of the logs end, in particular when the last roll or stack is cut off from the trimmed portion. In fact, since the trimmed portion is thin, the trimmed portion bends thus preventing the saw from cutting precisely.
a second problem of the existing machines is that the trimmed portions, at the beginning and end of the log, once cut, often lose their compact shape and become loose. In this way they disturb the outlet zone, where the belts cannot always convey them, and sometimes jam and block the passage of the rolls or stacks.
pushing devices are provided that, after that sensors distinguish the trimmed portions from the rolls, push selectively the trimmed portions sideways.
"traps" are provided, such as zones of fall of the trimmed portions obtained by distancing some belts so that they allow the passage of the rolls, which have larger size, causing only the trimmed portions to fall. In both these systems, the unevenness of the trimmed portions and their tendency to loosen cause the above-described problems.
an apparatus for conveying cut portions starting from logs of paper material and the like, such as for the production of rolls or stacks, and for removing the trimmed portions is arranged in a transversal cutting machine, which comprises:
said outlet means can at least in part displace themselves selectively for allowing the deviation of the trimmed portions with respect to the cut portions, whereby the trimmed portions do not reach the outlet means and can be collected.
the displacement of the outlet means allows the passage of the pushers also when they have large surface.
the outlet means comprises first conveyor means followed by second conveyor means, the first conveyor means moving away from the outlet zone at the moment of the passage of the trimmed portions after having carried the last cut portion of a log, whereby:
the first conveyor means preferably, move away from the outlet zone after a rotation about a fixed hinge. Alternatively, they move to the side, above or below the outlet zone.
the move away displacement of the first conveyor means has the advantages of allowing:
the pushers comprise a large flat element, for example circular, whereby the logs are pushed by a larger surface thus allowing a cut of the trimmed portions with fewer defects.
an apparatus 1 for conveying rolls 2 and removing trimmed portions 3, according to the present invention, is arranged downstream of a transversal cutting machine 4.
the latter comprises a loading and supporting bench 5 of logs 6 to cut into rolls, a cutting zone 7 of the logs 6 by means of a rocking saw 8 and a gripping device 9.
Apparatus 1 comprises a first conveyor belt 15 and a second conveyor belt 16 fastened to a base 17.
the first conveyor belt 15 is bound to the base 17 by means of a frame 18 pivotally connected about transversal hinges 19, whereby the conveyor belt 15, integrally to frame 18, can move away from the outlet zone by rotating to a position raised with respect to a transport plane 20 of log 6 and of rolls 2.
the transversal cutting machine 4 produces a row of rolls 2 up to the end of log 6. At every cut saw 8 lowers and gripping device 9 clamps log 6. At the last cut, the last roll 2a is separated from a trimmed portion 3a brought by pusher 10. Therefore, saw 8 severs the last roll 2a from trimmed portion 3a by dropping onto the end of the log.
quick conveyor 12 carries last roll 2a away, while trimmed portion 3a is brought, as shown in figure 1, towards apparatus 1.
first conveyor belt 15 As soon as last roll 2a has passed on the first conveyor belt 15, the latter is raised to the position shown with dotted line in figure 1, allowing at the same time the fall of trimmed portion 3a and the passage of pusher 10 that rotates about sprocket 22 following in succession the positions indicated with dotted lines.
the transversal cutting machine has started to cut a second log 6, and after the first cut a second trimmed portion 3b is severed and carried by quick conveyor 12.
a collector not shown receives trimmed portions 3a, 3b.
the first conveyor 15 is lowered by cylinder 21.
the above mentioned advantages are achieved disturbing the least possible the rolls to carry away, collecting in a "clean and safe” way the trimmed portions and, allowing the use of a pusher 10 of size large enough to allow a regular separation of the first or last roll from the trimmed portions by means of saw 8.
the first conveyor belt 15 can also be moved away from the outlet zone in a different way than that shown, for example by rotating it about a hinge longitudinal with respect to the direction of transport of the rolls, or displacing it vertically or horizontally, respectively above or at the side of the outlet zone.
