Definitions

  • the present invention relates to an extrusion line for the production of extruded plastic or laminate tube tubes with a relative to a base reciprocable carriage which is seated as a cutting device designed cutting device.
  • Conventional cutting equipment for extrusion plants for the production of extruded plastic or laminate tube tubes are known in many forms and designs in the market and in use. They serve in particular for the continuous cutting off of hoses, tube hoses or the like in an extrusion production process, wherein a movement of the cutting device is adapted to the outlet velocity or speed of the extruded tube, and at. Match is then cut off. Subsequently, contrary to the direction of movement of the extruded tube, the cutting device is moved back and synchronized to the exit speed of the tube for re-cutting. In this case, different cutting devices can be used.
  • the DE 38 03 553 A1 discloses a method and apparatus for cutting an endless longitudinal or spiral wound tube. In this case, the corresponding length is felt by means of a push-button and then the tube is correspondingly severed by means of a saw.
  • a similar linear motor in miniaturized form is from the US 6,025,659 described.
  • the US 4,724,027 discloses a method and an extrusion line with a mechanically driven pendulum stroke drive for linear movement of a table with arranged thereon cutting device.
  • a mechanical solution the speeds and the synchronization possibilities for achieving high accuracies are limited.
  • the present invention has for its object to provide a cutting device of the type mentioned, which eliminates the disadvantages mentioned, with which in a simple, accurate, precise and cost-effective manner, a slide with seated cutting device at much higher speeds for cutting hoses out and is movable.
  • a carriage by means of at least one linear guide, preferably by means of dovetail-like connections to a base, wherein in the carriage, in the region of the bottom and centrally between the linear guides a plurality of juxtaposed permanent magnets provided, or is / are used.
  • At least one coil is inserted or provided in the base, below the permanent magnets of the carriage, which actively activates a movement of the carriage back and forth depending on the control of the corresponding voltages.
  • the upstream of the cutting device transport device for control as a master and the actual cutting device or the carriage with the base as a linear motor forms the so-called slave.
  • the speed of the cutting device can be adapted to the exit speed of the tube to be cut off and, when synchronized, the tube can then be cut to length in the desired and any desired length.
  • the carriage of the cutting device are covered within a machine housing by means of diaphragms in order to avoid a risk of injury.
  • an extrusion plant A according to the invention for the production of extruded plastic or laminate tube hoses 1 only indicated here has an extruder 2 in which plastic material, also provided with additives, is extruded under the influence of temperature.
  • the material is then formed into a tube and cooled in a calibrator 3, molded and treated surfaces, wherein after exit of the following referred to as tube 2 plastic or laminate tube this is a transport device 4 is supplied.
  • the transport device 4 continuously supplies an extruded tube 1 of the cutting device R according to the invention.
  • the cutting device R is in essentially formed by a cutting device 5, which on a carriage 6, which is relative to a base 7, as shown in double arrow X, reciprocated.
  • the operation of the cutting device R is as follows:
  • the transport device 4 makes uniform a discharge speed of the hose 1, which is introduced into the cutting device 5. After insertion of the hose 1 in a desired length to be cut and lengthened during retraction of the hose 2 into the cutting device 5, it is adapted to the exit speed of the hose 1 and cut off during this synchronization.
  • the cutting device 5 is formed from an indicated blade unit 8 and a preferably servo-motor 9.
  • the servo motor 9 drives the blade unit 8 for driving a rotating blade, not shown here, for severing the hose 1 into individual pieces.
  • the severing of the tube 1 takes place during the movement of the cutting device 5 in the hose transport direction, at synchronized same speed.
  • the speed of the cutting device 5 is synchronized with the movement of the tube 1 or the extrusion speed.
  • the linear guides 10.1, 10.2 may have dovetail-like guide rails, so that only an exact linear guidance of the movable carriage 6 relative to the preferably stationary base 7 is possible.
  • the present invention has proved to be particularly advantageous in order to ensure very high accelerations of the carriage 6 and thus also the cutting device 5 seated thereon, that in the region of a bottom 11 of the carriage 6, as indicated by dashed lines in the embodiment according to FIG 4, a plurality of Permanent magnets 12 side by side over the full length in the carriage 6, in particular in individual recesses provided for this purpose 13, as indicated in Figure 3, are used.
  • the recesses 13 and the permanent magnets 12 inserted therein are preferably aligned perpendicular to the linear guides 10.1, 10.2, wherein the complete space between the two linear guides 10.1, 10.2 serves to reduce the dead weight.
  • the at least one permanent magnet 12 is preferably placed in the region of the recesses 13 of the carriage 6 between the linear guides 10.1, 10.2.
  • Webs 14 may be formed between the respective individual permanent magnets 12 in order to increase the stability of the carriage 6 with a low dead weight.
  • the tube 2 is guided over the transport device 4 and fed via a guide sleeve 16 which is connected to the base 7, a centering piece 17 of the blade unit 8.
  • the carriage 6 via the base 7 by means of at least one coil 15 as a so-called slave of the cutting device R upstream transport device 4, as the master controlled or regulated.
  • the base 7 and / or the linear guide 10.1, 10.2 is an incremental or associated with inductive length measuring system 18, which determines incrementally or inductively, the movement of the carriage 6 and thus the cutting device 5 relative to the base 7 continuously.
  • the buffer elements 20.1, 20.2 are, for example, provided with corresponding spring-damper elements 21, which cooperate with the stop 19 when exceeding a predetermined end position.
  • the stop 19 opposite, the base 7 inductive proximity switches 22.1, 22.2 are assigned, which are used in a reference movement of the carriage 6 of the zero point determination.
