Definitions
- the invention relates to a device for separating profile pieces of an extruded profile strand which is moved in its longitudinal extent, with a carriage which can be moved along the profile strand and which has a separating device with a saw blade and at least two clamping jaws for holding the carriage on the profile strand in a displaceably fixed manner, and with one with the clamping jaw - ken and the separating device connected control device which controls the clamping jaws and the separating device as a function of a predetermined profile piece length.
- a control device acts on at least two clamping jaws on the slide, in order to on the one hand connect the slide to the profile strand so as to be displaceable and on the other hand also to hold down the separation area of the profile string on the slide during sawing, whereupon the separation device for sawing through in a known manner of the profile strand is controlled.
- Devices of this type have proven themselves, but chips are produced during sawing, which chips, in addition to a higher expenditure of material, also cause dust pollution and contamination of the device, the environment or the profile pieces themselves. chen. These devices therefore have, in addition to protective devices against the chips being thrown away, also devices for collecting the sawdust, which means a comparatively high design effort.
- the invention is therefore based on the object of designing a device for separating profile pieces of the type described at the outset with a comparatively low design outlay so that, despite extrusion-related changes in the dimensions of the profile strand, the material loss when separating a profile piece can be kept as low as possible.
- this device is to be distinguished by its operational reliability and by a long service life.
- the invention achieves the stated object in that the cutting device is assigned a knife which can be moved transversely to the longitudinal extension of the profile strand and in that the control device comprises a selection circuit for selectively cutting off a profile piece with the saw blade or the knife.
- the separating device with the saw blade is also assigned a knife which can be moved transversely to the longitudinal extension of the profile strand, not only are there simple constructional conditions, since the slide already present for the saw blade is also used to carry the knife, but it can also jaws provided for the saw blade for the knife can be used. Because in the event that these clamping jaws do not hold down the profile strand exactly, this is not a problem for the rotating saw blade.
- the knife is only used according to the invention when the profile strand has a high degree of shape accuracy and the clamping jaws ensure an accurate holding down of the profile strand.
- the control device has a selection circuit with which it is possible to choose between severing a profile piece with the saw blade or the knife.
- the device according to the invention is comparatively inexpensive to manufacture, since the slide, control device and clamping jaws are used jointly by the saw blade and knife.
- control device takes into account a correction value as a function of the evaluation circuit when the clamping jaws and the separating device are acted on, the structural lateral distance between the knife and the saw blade can be taken into account when separating a profile piece.
- the control device can thus correct the position of the slide in relation to the professional piece with knowledge of the lateral distance.
- Simple design relationships result when the control device reads out the correction value from a memory as a function of the evaluation circuit, which correction value can be read into the memory of the device via an input device and can thus be changed.
- the knife consists of a knife disk which is rotatably mounted about an axis parallel to the longitudinal extension of the profile strand, when cutting the profile strand by rolling the knife on the carriage, the insensitivity of the knife to extrusion-related deviations of the profile strand from its required shape can be increased ,
- FIG. 1 shows a side view of the device for severing profile pieces with a knife guided vertically to the carriage
- FIG. 2 shows a detail of a severing device of FIG. 1, in which a horizontally guided knife is used instead of the knife guided vertically to the carriage.
- the device has a slide 3 which is displaceably mounted on guide rods 2 along an extruded profile strand 1 and which is moved via a displacement drive 4.
- the sliding drive 4 can only serve to return the slide 3 to its starting position, since the slide 3 can also be moved with the moving profile strand 1 by holding the clamping jaws 5 and 6 on the profile strand 1, which cylinder-actuated clamping jaws 5 and 6 are provided on the slide 3 are.
- a cutting device with a saw blade 7 and a knife 8 is provided on the carriage 3, the saw blade 7 driven by a motor 21 and the knife 8 being known to be movable transversely to the longitudinal extent of the profile strand 1.
- the knife 8 is clamped at both ends in guides which run perpendicular to the longitudinal direction of the profile strand at a distance from the profile strand, which enables the knife to be moved in the direction of the profile strand 1 in the manner of a guillotine.
- a drive 9 is provided for adjusting the height of the knife.
- Saw blade 7 and knife 8 are arranged laterally offset on the carriage 3 for the sake of simplicity. However, it is also conceivable to arrange the knife 8 and the saw blade 7 without lateral spacing in order to keep the slide length short.
- the carriage 8 also has recesses 10 and 11 for the saw blade 7 or the knife 8, the guides of the knife 8 being provided on both sides of the carriage.
- a control device 13 acts on the sliding drive 4, so that the carriage 3 is carried along with the moving profile strand 1 starting from its rest position (not shown in detail) in the region of the entry of the profile strand 1. Subsequently, the control device 13 controls the cylinders 14 and 15 in order to connect the slide 3 to the profile strand 1 so as to be displaceable or to hold down the profile strand 1 in the separation area on the slide. In order to support the holding down of the profile strand in the separation area, a further cylinder 12 with a clamping jaw can be provided, which is shown in broken lines in the drawing.
- a roller sensor 22 is provided, which is connected to the profile strand 1 and is connected to the control device 13.
- the position of the carriage 3 is known to the control device 13 via the sliding drive 4.
- the control device 13 can then control the severing device as a function of a selection circuit 16, namely that either severing by the saw blade 7 or by the knife 8 is to take place.
- the selection circuit 16 can, for example, record the accuracy of the profile strand 1 via sensors, so that a decision about the respective severing with the saw blade 7 or the knife 8 can be made from the device, which is not shown in more detail. But it is also conceivable that this decision is made by the operating personnel or is entered into the selection circuit 16 via a key.
- a housing 17 common to the saw blade 7 and the knife 8 is provided on the slide 3.
- the control device 13 calculates a correction value 18 when actuating the pusher drive 4 or the clamping jaws 14 and 15 in order to take into account the lateral distance between the saw blade 7 and the knife 8.
- This correction value 18 is stored in a memory 19, which can be changed via an input device 20.
- the knife 8 may consist of a knife disk 21 which is rotatably mounted about an axis 22 parallel to the longitudinal extension of the profile strand 1 (FIG. 2).
- the cutter disc 21 is rolled across the profile strand 1 in a groove on the slide 3, for which purpose a guide rod 23 is provided which is fastened to the slide 3, which was not shown in detail.
