Definitions
- the invention relates to a punching unit, in particular for Create a perforation for the binding spine for one Ring binding.
- Punching units for punching a punch for one Combs are from the prior art in a variety known of variations.
- a major problem with these known methods is that a hole in a stack of paper with a larger one It is very difficult to punch the number of single sheets.
- US 3,227,023 is a combined one Punching and binding machine for ring-like flexible Plastic binding elements known.
- the removable stops for the individual punching knives are also in relation to the horizontal contact surface with the Paper stacks are not executed in one plane, but theirs Distances from the contact surface take up from one side of the linear punching tool to the other. So that is achieved that the die cutters do not pierce the paper at the same time but one after the other. This also makes the Reduced power.
- the invention lies Task based on the punching process for the operator to simplify and make it more efficient.
- this object is achieved by a perforation unit, in particular for producing a perforation for a binding spine a ring binding with the following characteristics:
- the perforation unit has a preferably circular cutting disc rotatably mounted with respect to an axis of rotation with one or more cutting elements arranged on the circumference of the circular cutting disc, which protrude beyond a fictitious pitch circle with pitch circle radius r w .
- the perforation unit has a die, which in turn has a surface perpendicular to the cutting disk at a distance from the pitch circle radius.
- This die also has one or more recesses in which one or more of the cutting elements arranged on the circumference of the circular cutting disk engage simultaneously.
- a paper to be punched is arranged perpendicular to the cutting disc at a distance of the pitch circle radius r w from the axis of rotation of the cutting disc on the above surface of the die.
- the punching process does not take place as in the known Execution in a substantially linear movement of the Punching tool, but by a rotary movement of the Cutting disc kick the cutting elements first on one side into the paper and the recess in the die.
- the torque required for the rotary movement can for example with the help of a crank or by a motor drive, possibly coupled with a appropriate translation can be applied.
- the cutting elements are designed in such a way that their cutting edge projects beyond the pitch circle radius r w of the pitch circle.
- the recesses of the die each have the Cutting edges assigned to cutting edges.
- the cut edges of the cutting elements and the cutting edges of the recesses are arranged so that they are similar to each other How a pair of scissors work together along the sharp edges sliding the paper with a Cut the pulling cut.
- the process of punching is still similar to one Punching process, the effort (or the required torque) but is clear compared to a pure punching process reduced.
- the punching unit is designed so that the between the Surface normals of the surface of the die formed Free cut angle is chosen so large that a rubbing of the Side edges of the cutting elements on the walls of the Recesses in the die is avoided.
- Alternatively or in addition is one between a radial through the axis of rotation the circular cutting disc straight lines and Cut edges formed on the side edges of the cutting elements chosen so that rubbing the side edges of the Cutting elements on the walls of the recesses in the die is avoided. Both measures help to ensure that the further effort required to create a perforation is minimized.
- a particularly advantageous embodiment of the invention provides before that the cutting elements a material unit with the form circular cutting disc.
- This measure has in particular manufacturing advantages. For one, can Assembly costs for attaching the cutting elements to the circular cutting disc can be avoided. Second is the manufacture of the cutting disc with the cutting elements in possible in one operation.
- Another advantageous embodiment of the invention provides that the cutting elements at a distance from the pitch circle radius rw of cross-sections of the axis of rotation of the circular cutting disc have, which are essentially the cross sections of the producing perforation for the spine of the ring binding correspond. This measure ensures a consistently high level Quality of the perforation, which is at least comparable to the punched holes.
- the cutting elements have a cross section dovetail-shaped body.
- This basic body preferably has a constant axial thickness, which in Essentially a perforation width of the perforation to be produced corresponds.
- the width of the dovetail-shaped base body in the circumferential direction is given by the hole length of the hole to be produced at the distance of the outer radius r a from the axis of rotation of the cutting disk.
- the base body is delimited on its radially inner foot by side edges and on its radially outer surface by cut edges. Such a shape of the cutting elements is very easy to produce, especially when the cutting elements form a material unit with the cutting disk.
- the die surface is advantageously a flat plane trained, or it is on the circumference of a disc arranged so that they are essentially a cylinder jacket trains.
- the surface of the die moves perpendicular to the cutting disk at a distance of the pitch circle radius r w from the axis of rotation of the cutting disk at a peripheral speed of the fictitious pitch circle. It is irrelevant whether the die surface is fixed and only the circular cutting disk is moving or whether the circular cutting disk and the die are moving. Only the relative movement is decisive. In the case of a flat die, there is therefore no relative movement of the paper to the die itself in this embodiment of the invention.
- the invention provides that the number of cutting elements which are simultaneously in engagement with the recesses of the die can be selected variably. Such changeability is possible on the one hand by an appropriate arrangement of the cutting elements, on the other hand by an appropriate choice of the pitch circle radius r w of the pitch circle and / or the radius of the cylinder on which the die is attached. With the number of cutting elements simultaneously engaged in the recesses of the die, the effort or the necessary torque for the punching process can thus be selected.
- Form the cutting edges of the recesses in the die preferably boundaries which correspond to the cross section of the producing perforation for the spine of the ring binding correspond.
- a particularly advantageous embodiment of the invention exists in that the surface of the die and therefore the die even when turning the circular cutting disc stands. Such an arrangement is particularly useful if if the die surface is formed as a plane. In in this case there is only a single recess in the die necessary in the the cutting elements of the circular Engage the cutting disc one after the other.
- the paper arranged on the die is used for this Punching process with the peripheral speed of the fictitious Rolling circle of the cutting disc over the die surface moved away so that the cut edges of the cutting elements cut the holes in the paper.
- the cutting edges of the cutting elements are designed so that they not at the same time at the beginning of the punching process cut the paper. This is the case if the Cutting edges at different distances over the pitch circle radius protrude or have rising edges. Through this Measure the necessary cutting force and thus that necessary torque to be applied to the cutting disc further reduce.
- the perforation unit in Combination with a single sheet feeder and / or one Paper sorting system and / or a binding machine arranged is. Such an arrangement makes sense if the Binding process should be automated as such.
- FIGS. 1 and 2 show a first embodiment according to the invention of a circular cutting disc 1 with cutting elements 2 of the same material.
- a circular cutting disc 1 consists of a circular, generally metallic base body with a cutting disc thickness d s .

- the thickness of the dovetail-shaped base body of the cutting elements 2 thus corresponds to the cutting disk thickness d s .
- This dovetail-shaped base body is delimited laterally by side edges 7 and on its outer peripheral surface by cut edges 8.
- the cut edges 8 thus form a circular section in the circumferential direction with the cut edge length l s .
- a straight line running radially through the center of the circular cutting disc 1 and the side edges 7 of the cutting elements 2 enclose a free cutting angle, which is denoted by ⁇ .
- the cutting edge length l s of the cutting edge 8 formed by the preferably circular segment-shaped cutting elements 2 is in practice preferably about 2 to 10 mm.
- the embodiment continues circular cutting disc of the same material as cylindrical coupling element 4 continues.
- the outside diameter this cylindrical coupling element 4 is smaller than that Outside diameter of the circular cutting disc 1 on the there are the cutting elements 2.
- a coupling element with the help of Fastening elements (for example with the help of screws or the like) on the circular cutting disc 1 fasten.
- the coupling element is 4 and the circular one Provide cutting disc 1 with a central bore 3.
- the center of this central bore 3 forms the axis of rotation 27
- Central bore 3 serves to receive an axis 6.
- Die Central bore 3 has a circular in the example Cross section on. Another preferred embodiment is a polygonal cross section.
- the cylindrical coupling element 4 has a Radial bore 5 with internal thread in which a screw is used for the coupling element 4 without thread is executed.
- Figures 3 and 4 show a flat die 19, which has a two-dimensional flat surface.
- One or more recesses 20 penetrate the depth t 1 of the flat die 19.
- the cross section of the recess 20 of the die 19 on its surface corresponds essentially to the cross section of the perforation to be produced for the binding spine of the ring binding.
- the perforation to be produced for the binding spine has a rectangular cross section with the perforation width b L and the perforation length l L.
- the two clearance angles ⁇ and ⁇ of the circular Cutting disc 1 or the die 19 are preferably so large chosen that rubbing the side edges 7 of the Cutting elements 2 on the walls of the recesses 20 of the flat die 19 is avoided.
- FIGS. 9 and 10 show a further embodiment of the Invention in which the die 9 on the circumference of a disc 13 is arranged.
- the disc 13 with the die 9 on its circumference is in the Embodiment executed in two parts. it consists of a base body 16 with uniform material Coupling element 11 and a second disk 17th
- the base body 16 essentially consists of a circular disk of the base body thickness d G.
- This base body 16 has an axial bore with a depth which corresponds to the hole width b L.
- the radius of the bore corresponds to the inner radius r i according to FIG. 9.
- the outer radius of the base body is designated r a in the drawing.
- This cylinder jacket preferably has milled recesses 12. These recesses 12 correspond to the. Recesses 20 of the planar die 19 according to FIGS. 3 and 4.
- the cross section of the recesses on the outer circumference of the base body 16, which is formed as a cylinder jacket, essentially corresponds to the cross section of the perforations to be produced for the binding spine of FIG. 3 and FIG Ring binding, ie in the example a rectangular cross section with the hole length l L and the hole width b L.
- the coupling element which is in material unit to the Base body 16 is analogous to that of the circular Cutting disc 1 according to Figures 1 and 2 executed.
