Definitions
- the invention relates to a knife holder for a circular knife rotatably mounted in a knife head for the longest cutting of material webs, in particular material webs made of paper or plastic film, the knife holder being provided with a hand guard.
- a knife holder for roll cutting machines which has a hand guard which is supplemented on the side facing the counter knife by at least one can segment which can be actuated via a separate piston-cylinder unit which is operated with the piston-cylinder unit is connected in series.
- the can segment In the position of the circular knife which is raised from the counter knife, the can segment is closed by spring force.
- both piston-cylinder units are acted upon by the pressure medium, so that the can segment in Swivel the handguard in and release the cutting edge of the circular knife.
- Such a knife holder proves disadvantageous in that, in addition to the high construction costs for an additional piston-cylinder unit, a larger width of the knife holder is necessary.
- EP-A-0 562 454 shows a similar arrangement with a two-part protective hood, the part of the protective hood facing the counter knife, designed as a can segment and provided with a slot, being vertically displaceably mounted.
- the can segment is moved via a separate piston-cylinder unit.
- the can segment In the raised position of the circular knife, the can segment is held in the closed position by a closing spring and is retracted when lowering over the piston, so that the cutting edge of the circular knife can pass through the slots.
- a hand guard designed in this way is complex and prone to failure due to the multi-part construction and the necessary complicated adjustment mechanism.
- EP-A-0 333 001 shows a knife holder with a protective hood as hand protection, which is fixedly attached to the base body of the knife holder and completely covers it in the raised position of the circular knife. When lowering the circular knife against the counter knife, the circular knife moves out of the fixed protective hood.
- DE-U-90 12 926 also shows a knife holder for reel cutting machines, in which the circular knife is surrounded on the side and on the side facing away from the counter knife by a firm hand guard, and the cutting area of the knife is covered by a movable segment which is likewise covered by a complex drive device is opened and closed.
- the invention is therefore based on the object of providing a knife holder for circular knives which, with a small overall width, good functional safety for hand protection with the simplest possible construction guaranteed.
- the object is achieved by a knife holder for a bearing mounted rotatably in a knife head
- Circular knife for the longitudinal cutting of material webs, with a base body which can be fastened to a cutter bar, on which the cutter head is mounted so that it can be moved back and forth via a cross-member between a rest position and a cutting position, and with a protective hood covering the circular knife over at least part of its circumference is movably mounted relative to the circular knife so that in the cutting position the area of the cutting edge which is in engagement with a lower knife is exposed and in the rest position the cutting edge is at least protruded laterally by the protective hood, and with a return spring between the protective hood and the crossbar is arranged to hold the protective hood in the cutting position of the circular knife in a working position releasing the cutting edge of the circular knife, and that in the rest position of the circular knife the protective hood presses through a stop arranged on the base body into a protective position in which the circular knife esser is covered by the protective hood.
- the advantage of a knife holder designed according to the invention is that, in the rest position of the knife head, the worker is protected from injuries from the circular knife edge, the rest position of the knife head in the sense of this invention being understood to mean the position in which the circular knife is raised from the associated lower knife . In the rest position of the circular knife, the worker can make adjustments to the knife holder and / or
- the return spring which acts between the crossmember and the protective hood, can be designed, for example, as a leg torsion compression or tension spring.
- the protective hood which is designed in one piece in accordance with the invention, enables simple and reliable protection of the worker against injuries from the circular knife edge in comparison with the known prior art.
- the fact that the only one-piece protective hood has to be moved eliminates the more complex constructions, which require a segment that can be moved in addition to a rigid protective hood to protect against the circular knife and which has to be moved by separate drives.
- the simple protective function of the protective hood is ensured in that, as soon as the cutter head is lifted off the lower cutter, the protective hood is automatically pressed into the protective position by means of the stop arranged on the base body, so that the circular knife edge is completely covered in the rest position of the cutter head.
- the stop located on the base body presses the protective hood in the direction of the lower knife.
- the protective hood is pivotally mounted in the plane of the circular knife.
- a bearing element acting between the crossmember and the protective hood is provided, around which the protective hood can be pivoted, so that in the working position the protective hood is pivoted through an angle relative to the protective position.
- the protective hood is slidably mounted to the circular knife.
- a protective hood slidably mounted to the circular knife is mounted so that the protective hood is trans- is mounted movably in the direction of the lifting and lowering movement of the cutter head.
- the protective hood can be mounted, for example, by bolts which are connected to the protective hood and which are guided in at least one elongated hole arranged in the crossmember. It is expedient if an elongated hole is arranged on both sides of a circular knife axis, the length of which extends in the direction of the lifting and lowering movement. It is also possible for the bolts to be connected to the crossmember and to be guided in an elongated hole arranged in the protective hood. It is also possible for the cross member to have a groove in which a sliding block connected to the protective hood is guided.
- At least one guide element acting between the cross member and the movable protective hood is provided.
- the advantage of a guide element acting between the crossmember and the protective hood is that it is particularly pivotable in the plane of the circular knife
- Protective hood this is also connected to the crossbar, which results in better storage and guidance of the protective hood.
- a guide element in particular prevents the protective hood from bending out laterally against the plane of the circular knife.
- a guide element connected to the protective hood can, for example, engage in an elongated hole or a groove arranged on the crossmember, the elongated hole or the groove expediently having the shape of a circular arc which is swept by the guide element during a pivoting movement of the protective hood.
- the stop is adjustable.
- an adjustable stop it is possible to adapt it so that, depending on the application, the optimal protective and / or working position of the protective hood can be adjusted.
- the protective hood is approximately circular, the outer diameter of the protective hood being larger than the diameter of the circular knife, so that the cutting edge of the circular knife is completely covered in the protective position.
- an edge which is angled vertically to the circular knife plane and which extends at least over a partial area of the circumference of the protective hood is arranged on the protective hood.
- the edge which is angled vertically to the plane of the circular knife ensures that on the one hand the circular knife edge is covered at least over a partial area of the circumference and on the other hand one side of the circular knife remains accessible in order to be able to adjust, change and / or adjust the circular knife from this side.
- no edge is arranged on the side of the protective hood facing the lower knife, so that the protective hood in the working area of the circular knife is covered only by a part of the protective hood running parallel to the knife plane in the rest position.
- the angled edge extends over the full circumference of the circular knife and has a slot-shaped opening for the circular knife edge in its area assigned to the cutting position.
- the fact that the angled edge has a slot-shaped opening in its area assigned to the cutting position means that when the protective hood is moved into the working position, the circular knife edge can pass through the slot-shaped opening.
- the cutting edge is covered by the angled edge with the slit-shaped opening, thereby avoiding injuries to the worker.
