Definitions
- the present invention refers to an anvil for rotary grooving machines and die cutters, with which the transformation of cardboard sheets for the manufacture of boxes and packaging is achieved.
- the machinery used for the manufacture of cardboard packaging, from plates, are called transforming machines and one of its main characteristics is to make the necessary cuts and the marking of the folds in the cardboard plates, which they will allow to form the box or packaging.
- these machines have in common a part that incorporates the necessary elements to cut and split cardboard (heads of blades, dies, etc.) and another part, which acts as anvil or support of the iron cardboard and gives the consistency necessary for the cutting or marking of the crease to occur.
- a butcher's knife and the wood it uses as a support, where the knife after cutting the meat is introduced into the wood. This wood with functions of anvil or sufridera gave first consistency to the piece of meat that had to be cut, and then the knife penetrated the wood without deteriorating its edge.
- the process of cutting cardboard sheets and marking them for packaging formation is called grooving or die cutting.
- the machines that normally do it can be designed to work with the aforementioned elements of cutting and creasing the cardboard, in a flat way (die or blade distributed on a flat surface that works against an also flat anvil), or , the shaping of the die and arrangement of the blades is made on the surface that develops a cylinder, and in this case it is designed in a cylindrical way or as a ring.
- a surface for the anvil of rigid material (steel) is used in these machines, when in the rotary die and due to the unfeasibility of having dies with that precision, the surface is used use of supports or anvils of soft material, which counteracts the difficulties of the rotary die.
- the cylindrical anvil is formed by a series of bushings or rings that are juxtaposed until they reach the total length of the support cylinder.
- This set of bushes or partial anvils can be installed in two different modes: a) the set of anvils rotates with the cylinder, and for this inside the bushing there is a key that is inserted into the transverse groove of the cylinder. The anvils during work do not separate because the end stops block them forming a single set. b) the set of anvils rotates freely on the cylinder.
- the anvil for slotting machines and rotary die cutters which is the object of the invention, has the advantages of the previous systems and, taking advantage of new materials, corrects the inconveniences that were previously presented. With respect to the most recent bands, it is considerably improved in the ease and speed of assembly, with a completely innovative design, the quality of work when using the vulcanized and being a rigid, light and stable core will be recoverable and reusable. As already mentioned, given the current requirements, any of the three characteristics alone would already imply acceptance by the users.
- the system presented has the following three advantages:
- the quick coupling system for the interconnection of both pieces includes a wavy profile on the connecting fronts of both, counting in points facing the lace pins and the respective complementary housings.
- the thrust pins follow an annular direction and are each provided with a projection in the shape of a harpoon tip and axial direction, in a preferred embodiment. These pins also have a chamfer or cut at the free end but in the opposite part to the emergency of the projection in harpoon, thus materializing the initial point of attack of a piece against the ramp side provided in the corresponding housing of the other piece .
- This receiving housing has a lateral widening of the projection at the tip of the harpoon.
- the hooks with their harpoons or projections that allow the quick connection of the "male” and “female” bushing have a design so that they offer the least resistance when assembling and disassembling each anvil.
- Another improvement consists in providing for the assembly of connecting clips that allow the interconnection of all the caps that are juxtaposed to form the cylindrical roller or annular band that materializes the composite anvil.
- These staples have a "U" shape and their branches are introduced into the respective housings of the inner wall of the bushing, very close to the edge of it.
- One of the ends of the clip is embedded before mounting, in a "female” and when the anvil is mounted on the cylinder, the flexible part and the end to be inserted into the next anvil protrude laterally.
- These staples of each anvil are advantageously located in the "female” portion and in number of three.
- On the opposite edge each "female” has the lace gaps to receive the staple of the anterior anvil.
- the three clips have the function of joining the anvils laterally, but only the central one also prevents an anvil from advancing with respect to the adjacent one, in the direction of rotation during the work.
- the two end clips do not perform this function, since their design must allow the assembly of the next "female” approaching it in the direction of the radius, in addition to the possibility of fixing them by moving the piece laterally.
- Both safety latches and tie clips are designed in such a way that, in addition to performing their function satisfactorily, they do not harm the main objective of the system, which is the rapid change of anvils.
- the third of the advantages incorporated into the anvil that occupies us is determined by the elastic stop that is installed on the anvil-holder cylinder, at its ends.
- the elastic stop In addition to its function of making a lateral stop mind to the set of anvils, has the characteristic of allowing its assembly and disassembly easily, since in some cases and depending on the position of the assembly, more space is needed, in addition to the initial clearance, between the last partial anvil and the stop for disassemble the "male" portion thereof, and said portion is disassembled by lateral displacement.
- the end of the cylinder can be released without increasing time.
- Another additional characteristic is defined by the possibility of changing this stop by another of different width, since as we have indicated previously, some clearance between the set of anvils and the stops was required. This clearance can vary after several hours of work, due to dilations in the anvils of the staples that, although they will be minimal individually, it should be taken into account that each partial anvil or bushing is approximately 230 mm wide and for an average machine width 2500 mm, ten units are required. This variation can be compensated with the use of different widths of stops.
- Figure 2. It is a schematic perspective view of a cylindrical die and anvil, used in conventional rotary die cutting.
- Figure 3. It is a schematic perspective view of a conventional cylindrical anvil with disposable bands, in this case steel sheets.
- Figure 4. It is a view similar to Figure 3 of a conventional anvil provided with a soft vulcanized material on aluminum.
- Figure 5. It is another view similar to Figure 3, of an anvil covered by a band with fiberglass and a hook system of the same also conventional.
- Figure 6. It is a view similar to Figure 4, with the anvil provided with a replaceable band disposed on a rigid bushing, in the conventional manner.
- Figure 7. It is an exploded perspective view of the replaceable anvil band, according to the invention, including the quick assembly system, formed by a rigid core and a cut resistant material that is vulcanized on the core.
- Figures 8 to 11.- They are different schematic views in which the assembly sequence of the two component parts of the tubular part that materializes the anvil object of the invention, according to Figure 7, is shown.
- Figure 12. It is a partial and perspective view of an anvil for slotting machines and rotary die cutters, which incorporates the improvements object of the invention, specifically those defining the safety latches and the joining clips.
- Figure 13 It is a perspective view of the elastic stop that is to be located at one of the ends of the support cylinder of the bushing assembly mounted on the support cylinder, shown partially.
- Figure 14 It is a perspective view of a portion of the anvil where the inner chamber is shown that allows the formation of the air mattress for displacement of the bushings or partial anvils mounted on the support cylinder.
- the flat die carrying the blades 2 is conventionally referenced, being conventionally made of wood.
- the flat die 1 attacks on the steel anvil 3 to produce the die cut 4 in the corrugated cardboard sheet or the like 5.
- the band 11 is materialized by a thin sheet of steel as a support material, coated with soft material.
- the ends of the band 11 are anchored to the core 12 as it has a longitudinal groove 13.
- the anvil is generally referenced with the number 20 and constituted by a rigid core with a layer 22 of cut resistant material, vulcanized on said core 21.
- the carrier For assembly in the carrier, it is divided into two parts 23 and 24 and one of them having a slightly higher development than the other.
- the quick coupler system of both pieces 23 and 24 components of the anvil 20 includes a wavy profile 25 as a finish of the ends or fronts of both parts, existing in one of them the pins
- the force Fe decomposes into a resulting force in the direction of movement (FR,), and another force normal to the surface (FN) .
- the force (Fr,) is the component of (ER) in the direction of entry into the housing.
- ER the force normal to the surface
- the pins 26 have a chamfer or cut-out 28 at the point of contact A with the housing 27.
- Figure 11 shows the position of snap and ring closure. So that the blocking can be done perfectly and without If there are problems, the pins 26 inserted in the core portion 24 have soft polyurethane areas that absorb the impact and then act to make the blockage effective.
- the soft or elastic zone is located on the left side of figures 8 to 11 and the pin that materializes the projection 29 in harpoon tip is inserted therein. In figure 10 the elastic behavior of this projection 29 is schematically shown with dashed lines until it fits into the widening 30.
- Figure 9 also shows the force diagram at a time of coupling, after that of Figure 8.
- Fe 2 designates the thrust force (at the time that indicates the position of the drawing); FN 2 is the component in the normal direction to the surface, FR 2 is the component force in the direction of movement (this direction of movement is represented by an arrow 31).
- Fr 2 is the FR ⁇ component in the direction of entry to the accommodation.
- the coupling system contemplated by the invention is possible due to the quality of the material used in the core, since it is a lighter, stronger and more stable material than previously used.
- Figure 7 shows the design of the section of the anvil 20, which makes it possible to give great strength and considerably reduce its weight, as well as to allow a correct width of the contact tracks with the cylinder holder.
- Another step in the development of new forms of rotary die cutting and taking advantage of the new materials is also to use a rigid counter-die, preserving the hooking system that is recommended.
- the bases or cores could be the same, coated or vulcanized with a new material or forming a single assembly.
- each of the bushes that are juxtaposed on the support cylinder is formed by the union of two parts: the "male” portion 34 and the “female” portion "35.
- the support cylinder is referenced with the number 36 and shown schematically in Figure 14 and the complete bushing or partial anvil, is generally referenced with the number 37.
- the anvil or counter-die assembly is generally referenced with the number 38 and is formed by placing the bushes 37 coaxially on the support cylinder 36.
- the clips 47 are located in the "female" portion 35, specifically in the respective recesses or housings 48. On the opposite edge there are the lace gaps 49, the interlocking being realized by counting the clip 47 with an elastic core and a harpoon-tipped end 50 that defines an inclined plane that slides along the existing one also in the adjacent "female" part, at the entrance of the hole 49.
- the pre-assembled housings 48 of the clip 47, as well as the recesses 49 that receive the clip 47 of the previous bushing, are duplicates and this arrangement allows to place a "female" of a partial anvil, advanced or delayed with respect to the "female" of the anterior anvil, as seen in Figure 14.
- the clips 47 connect with a certain pressure, in such a way that it does not offer difficulty in its extraction, but that there is sufficient support to serve as protection for the edge of the anvil. Thus, when an operator manipulates the anvils they can drop them to the ground (on the edge of the clips 47) without damaging the edge of the sleeve or the edge of its coating.
- the central one has the second end with a different design than the two that are located at the tips.
- the elastic stop that is mounted at the ends of the anvil-holder cylinder 36 is referenced with the number 51, having the open annular shape that we had previously contemplated and a section in which a inner rib that is housed in a throat provided on the periphery of the cylinder 36, for its axial immobility after the fastening of its ends by means of the closure strap 52.
- the distance between the elastic stop 51 and the end cap or anvil 37 of the assembly It can be adjusted when there are elastic stops 51 with different widths, as previously indicated.
