Definitions
- the purpose of the present invention patent application is to register a counter-die cylinder for a die cutting machine that incorporates notable innovations and advantages.
- the invention refers to an applicable counter-die cylinder, especially a rotary die-cutting machine of sheet material comprising a rotating cylindrical body on its own axis, at least one tubular element disposed on the cylindrical body and a blanket arranged around the corresponding said tubular element, which allows the displacement of the tubular element in an axial direction.
- a type of rotary die cutting machines for example, those used for the manufacture of boxes from corrugated cardboard sheets based on passing a corrugated cardboard sheet between two cylinders, are provided with a carrying cylinder - die in which the die is mounted and a counter-die cylinder provided with blankets that are usually made of plastic material with a laminar shape, such as polyurethane, where the blades are cut to cut the corrugated cardboard.
- the blankets usually wear irregularly over time due to repeated penetration of the blades of the die, causing areas with a significantly smaller diameter and consequently, areas of less penetration or lower pressure of the blades, a fact that can cause problems during die cutting operations to such an extent that it can prevent cutting and / or cause splitting problems.
- a first known solution to avoid irregular wear is to rectify the surface of the blankets periodically. However, this solution requires a production downtime and / or in turn causes accelerated wear of said blankets.
- Another solution known by the holder to reduce this inconvenience is to apply a slow (and small) axial movement of the counter-die cylinder so that the worn area of said counter-die cylinder is more distributed and not centered on a single region. . Said solution fails to completely solve this problem, since it produces grooves the size of the displacement of the counter-die cylinder, whose amplitude is limited by problems of space between terraces (approximately limited to 50 millimeters).
- the present invention has been developed in order to provide a counter-die cylinder that resolves the aforementioned drawbacks, also providing additional advantages that will be apparent from the description that follows.
- a counter-die cylinder for a die-cutting machine of sheet material of the type comprising a rotating cylindrical body on its own axis, at least one tubular element, delimiting two opposite endpoints (for example, by the side edge itself or by means of stop rings located at each of the ends), which is arranged on the cylindrical body and at least one blanket arranged around the corresponding said tubular element, and is characterized by the fact that it comprises means of displacement linked with the stop rings to move the said tubular element in a longitudinal direction with respect to the axis of the cylindrical body, such that the position of the tubular element is likely to vary along the length of the cylindrical body, such means being of displacement driven by automated drive means.
- the blankets can be moved axially automatically without presenting the aforementioned drawbacks, that is, the life of the blankets is extended without the need to carry out a grinding of the blankets since it carries out uniform wear of the blankets and in turn the entire movement of the described assembly is automated to move said blankets.
- the displacement means and the automated actuation means are located inside the cylindrical body. In this way, an additional space is not required to dispose of the movement mechanism for the blankets when taking advantage of the interior space of the cylindrical body that is usually internally hollow and empty and, consequently, there are no interference problems with other equipment or components of machine.
- the displacement means comprise at least one pushing element associated with the automated actuation means.
- the counter-die cylinder comprises a counter-pressure element that exerts a force opposite to the force exerted by the thrust element.
- the thrust member comprises a pusher member located on an axially movable shaft that passes through the inside of the cylindrical body provided with a motor that can be of the geared motor type, the pusher member being in contact direct with a stop ring arranged at one end of the tubular element.
- the counter-pressure element comprises a pneumatic cylinder housed in a fixed way inside the cylindrical body that includes a pusher member that is in direct contact with a second stop ring disposed at the end end opposite the front end end.
- the pusher member that is part of the thrust element and the counter-pressure element comprises an annular body provided with at least one retaining flap protruding outwards and movable along a regatta located in the cylindrical body, the annular body being fixedly attached to a spindle connected to the motor and the pneumatic cylinder, respectively.
- the displacement means and the automated actuation means can be located outside the cylindrical body.
- the cylindrical body of the cylinder against ⁇ die is provided with at least one access hatch for easy and practical access to the interior thereof, so that in the case of maintenance or repair or replacement of any of the components that they can be located inside does not require the complete disassembly of the cylinder against ⁇ die.
- the counter-die cylinder comprises synchronization means, such that the linear speed of the displacement means is synchronized with the rotational speed of the cylindrical body. rotary.
- Such means are connected with a control unit of the machine in which the cylinder is disposed against ⁇ die.
- Figure 2. It is an enlarged detail view in partially sectioned perspective of a section of the counter-die cylinder where the automated drive means are located;
- Figure 3. It is an enlarged detail view in perspective of the section of the partially sectioned counter-die cylinder where the counter-pressure element is located;
- Figure 4. There are three perspective views of the counter-die cylinder of the invention in three different positions;
- Figure 5. It is a front elevation view of a second embodiment of the counter-die cylinder of the invention.
- Figure 6.- It is a perspective view of the embodiment shown in Figure 5. DESCRIPTION OF A PREFERRED EMBODIMENT
- an embodiment of the counter-die cylinder for a die-cutting machine of sheet material (not shown), generally indicated by reference 1, especially suitable for die-cutting of corrugated cardboard boxes, comprises a elongated cylindrical body 2 rotatable on its own axis that is horizontally coupled to the frame or bed of the die cutting machine by means of two circular metal end plates 9, 10, which are each provided centrally with a support shaft and rotation 16, 17 respectively through which the rotational movement is transmitted to the counter-die cylinder 1 in a known manner so that it will not go into greater detail.
- a plurality of aligned tubular elements 3 are provided on the outer surface of the cylindrical body 2 and a plurality of blankets 4, for example, of Polyurethane, each of which is arranged around of its corresponding tubular element 3.
- the counter-die cylinder 1 is provided with displacement means, which will be detailed below, which allow a displacement in a longitudinal direction of the tubular elements 3 together with the blankets 4 with respect to the axis of the cylindrical body 2, such that the position of the tubular element 3 is likely to vary along the length of the cylindrical body 2 performing a relatively slow reciprocating movement of the blankets, that is, from one end to the other of the machine bed on which the counter-die cylinder 1 is arranged, such displacement means being actuated by automated actuation means which they can be operated by means of a push button located in a part of the die cutting machine or they are connected to the operation of the counter-die cylinder 1.
- displacement means which will be detailed below, which allow a displacement in a longitudinal direction of the tubular elements 3 together with the blankets 4 with respect to the axis of the cylindrical body 2, such that the position of the tubular element 3 is likely to vary along the length of the cylindrical body 2 performing a relatively slow reciprocating movement of the blankets, that is, from one end to the other of the
- said displacement means comprise a pushing element 5 associated with the automated actuating means and a counter-moving counter-pressure element 6 that exerts a force opposite to the force exerted by the pushing element 5.
