Definitions

  • the present invention relates to an improved device for the continuous cutting of strip-like or strand-like material, in particular man-made fiber cables, and an improved method for cutting this band-like or strand-like material.
  • a cutting device for fiber cables is known from EP-A-305,057.
  • This device contains a knife basket with cutting knives and a pressure roller that presses the fibers against the cutting knives.
  • This device is characterized in that it contains a means by which the angular position of the cutting wheel with respect to the pressure roller can be determined, that it contains a means by which the contact pressure exerted by the pressure roller on the cutting knives can be determined, and that it contains a means by which the quality of the cutting knives can be determined depending on the angular position of the cutting wheel and the pressure exerted on the cutting knives.
  • DE-A-3,311,190 describes a device for cutting ribbon-like or strand-like material, which comprises a knife basket with two knife support disks arranged axially one above the other with approximately knife length spacing, between the corresponding spacing in the desired stack a plurality of radially outwardly directed knives are held, and at least one pressure roller is associated with them outside at a distance to achieve a radially inward-acting cutting pressure on the wound fiber cable.
  • the known device is characterized in that more than just one pressure roller is assigned to a knife basket. With the known device, a large output of cut material is available, without this resulting in a greater load on the cutting knives.
  • a method and a device for monitoring the cut of a staple fiber cutting machine is known, in which the cutting ability of each individual cutting blade is determined and a signal is generated when the pressures are too high or too low, which can be used to switch off the staple fiber cutting machine .
  • the device described contains two measuring elements with which the position of the cutting knife and the deflection of a pressure roller is determined. A targeted control of the pressure force during the cutting process is not proposed.
  • Such knife breaks can result in the knives falling out of the holder and cutting no longer taking place at the point in question, as a result of which excessively long fibers are produced. Furthermore, the winding material can pile up on the cutting device in continuous operation after a knife break, in which the knife does not fall out of the holder.
  • the pressure rollers must apply an additional pressure in addition to the cutting pressure, with which the further transport of the cut stacks along the knives into the interior of the cutting wheel is accomplished.
  • the proportion of the pressure to be used for the actual cutting process is relatively small compared to the proportion of the pressure to be used for the further transport of the cut stacks along the knife.
  • the knives blunt, and the portion of the cutting pressure can be a multiple of the portion of the pressure to be used for the further transport of the cut stacks along the blades.
  • the object of the invention is to provide an improved method and an improved device with which it is possible in a simple manner to control the quality of the cutting knives, the quality of the to keep the cut goods constant over a long period of time, to increase the service life of the cutting knives, to adapt the cutting conditions to the different materials in a simple manner and to minimize the problems in the case of defects in the cut goods.
  • the invention is based on the knowledge that there are special advantages when cutting such a good thing, if the pressure roller is suspended and if it is in normal operation at a constant distance from the cutting wheel.
  • the constancy of the distance is desirable since, when this distance is varied, the material already wound on the cutting wheel can shift perpendicular to the cutting direction, so that transverse forces can occur which should be avoided if possible.
  • the pendulum suspension is desirable because it allows a gentler cutting process, especially in cutting devices with multiple pressure rollers.
  • the device according to the invention is characterized in particular in that the force acting on the material to be cut can be changed in a simple manner as a function of the knife quality with the distance between the knife and the pressure wheel being as constant as possible and in that means are provided with which the knife breakage is as simple as possible or other irregularities, an error message is displayed to the operating personnel and / or the device is stopped.
  • the devices according to the invention can each contain the opening and closing device (5), the actuator (6) and the damping member (7) as separate components. However, these components can also be partially or completely combined in one component.
  • the cutting wheel (1) in the device according to the invention can be designed in all known ways.
  • the cutting edges of the knives can point in the direction of the axis of rotation of the cutting wheel.
  • Cutting wheels of this type are e.g. in DE-A-2,720,918.

It is therefore a cutting wheel (1), which consists of a knife basket (2) with two axially one above the other with approximately Knife length spacing from each other is provided between the knife support disks, between which a plurality of radially outwardly directed knives (3) are held in the desired stack.
  • any device suitable for this purpose can be used as the opening and closing device (5). These are usually movement devices with the aid of which machine parts can be moved over larger distances in the cm or dm range for retooling or maintenance of the cutting device. Examples of these are mechanically, hydraulically, pneumatically or electromechanically driven devices.
  • the device according to the invention contains at least one, preferably an actuator (6) with which a predetermined distance between the pressure roller (4) and the cutting wheel (1) can be set.
  • an actuator (6) With this actuator (6) an initial state of the cutting device is defined at the start of operation and during operation this actuator serves to reset the distance which changes during operation to the originally specified value.
  • Any device suitable for this purpose can be used as the actuator (6). These are usually movement devices with the aid of which machine parts can be moved over smaller distances in the mm range or below. Examples of this are - as in the case of the opening and closing device - appropriately adapted mechanically, hydraulically, pneumatically or electromechanically driven devices.
  • the attenuator (7) is a vibratory mechanical system; this is characterized by a force-elongation characteristic.
  • This component can be, for example, a spring or a spring assembly, or any other device with which a force-expansion characteristic corresponding to a spring can be specified, for example a computer-controlled mechanical or electromechanical component with which a desired force-expansion Curve can be set.
  • Springs or spring assemblies for example spiral, leaf or disc springs, are preferably used as the damping member (7). It can be tension or in particular compression springs. Disc springs are very particularly preferably used, since these can be used to easily produce Kratt strain characteristics of the most varied steepness.
  • the damping member In addition to the setting of the contact pressure on the band-shaped or strand-like material resting on the knives (3), the damping member also serves for the effective weakening of force impacts of the pressure roller (4), which are triggered by a bottleneck between the cutting device and the pressure roller when it passes through a defect.
  • any device suitable for this purpose can be used as the distance measuring device (8) with which the distance between the pressure roller and the cutting device can be monitored.
  • this distance measuring device (8) either a direct measurement can be carried out or an indirect measurement is preferably carried out with which the distance can be deduced. Indirect measurement is preferred because the position of the distance measuring device in the cutting device can be freely selected in this case.
  • the distance measuring device can be, for example, a line marking which is attached to any component which changes in length during the operation of the cutting device and which is compared with a fixed location, for example a location on the housing.

  • two pressure rollers (2) are provided, which are arranged approximately opposite one another.
  • the contact pressure exerted on the strip-like or strand-like material lying on the knives is mainly applied by the pressure roller.
  • This contact pressure is set at the start of operation, among other things, by the choice of the predetermined distance between the pressure roller and the cutting device.
  • the material to be cut is wrapped around or on the knife basket and is transported through the constriction between the pressure roller and the cutting device. This creates a cutting force and the inner layer of the material to be cut is cut by the knife edges and transported out of the cutting wheel through the spaces between the knives.
  • the cutting speed decreases and the amount of material wound on the cutting device increases.
  • the distance between the pressure roller and the cutting device increases.
  • the device according to the invention provides an attenuator with which, in cooperation with the actuator, the contact pressure exerted by the pressure roller on the strip-like or strand-like material resting on the knives is set can be, so that the cutting performance of the device remains practically unchanged within a predetermined interval of contact pressures.

  • a radially inwardly directed cutting pressure acts on each of the individual knives arranged in the area of the pressure roller (4), which cuts the fibers of the innermost layer on the cutting edges of the knives.
  • the resulting stacks are pushed further radially inwards into the cutting wheel (1) by the subsequent fibers and then transported vertically downwards.
  • the pressure roller (4) is held by the lever arm (10) which is attached to the housing (13) via a joint (11) and which is connected to the axis (15) of the pressure roller (4).
  • This lever arm (10) is in turn articulated to a linkage (9) via which the opening and closing device (5), the actuator (6) and the damping member (7) act on the lever arm (10).
  • the linkage (9) is articulated at its other end to the housing (13).
  • the lever arm (10) also contains a distance measuring device (8) with which the distance between the pressure roller (4) and the cutting wheel (1) can be monitored. In the device shown, this is done by indirectly measuring the distance between the distance measuring device (8) and the stop (14), which in turn is attached to the housing (13).

  • the change in length of the linkage (9) is indicated by the distance measuring device (8) and can be reversed by actuating the actuator (6).
  • the force exerted by the damping member (7) via the linkage (9) on the lever arm (10) is increased again, and thus also the contact pressure exerted by the pressure roller (4).
  • a new stationary operating state has now been achieved, which is characterized by an increased contact pressure compared to the initial conditions and a practically equal distance between the pressure roller (4) and the cutting wheel (1).
  • the decreasing cutting speed of the knives that wear out during operation is compensated for.
  • the adaptation process described can be carried out several times during operation and, in particular, can be regulated without transition, the cutting speed of the device being able to be kept practically unchanged within a predetermined interval of contact pressures. The service life of the knives can thus be increased considerably.
