Definitions

  • the invention relates to a sawing device for splitting plate-shaped workpieces with the features of the preamble of claim 1.
  • Such sawing devices are known from WO 02/26452 A1. With their help, plate-shaped workpieces, in particular wood or plastic plates can be divided, wherein the saw cuts can be performed both parallel or perpendicular to a longitudinal edge of the workpieces as well as obliquely to the longitudinal edge.
  • the saw cut is carried out by means of a saw unit, which is held on a saw carriage, which can be moved along a saw line to make the saw cut.
  • the workpieces can be positioned by means of a feed device at the level of the saw line.
  • the feed device comprises at least one clamping device for detecting the workpieces, so that they can be positioned reproducibly.
  • the workpieces are reliably held on the support table by means of the hold-down device.
  • a hold-down device for example, a vertically adjustable held pressure bar can be used.
  • a first stop element is arranged in the form of a stop bar on the feed device.
  • a second stop element is held immovably on the support table, and a third stop element is arranged on a plate-shaped support device which is parallel to the saw line is mounted adjustable on the machine frame. By adjusting the plate-shaped support device, the third stop element can be moved relative to the second stop element, so that to be applied to the two stop elements workpieces relative to the saw line can take different orientations.
  • a manual setup of the workpieces with respect to the saw line can be omitted.
  • the use of a plate-shaped support device which is adjustably held on the machine frame can cause a disturbance sensitivity of the known sawing device and is associated with not inconsiderable manufacturing costs.
  • Object of the present invention is to provide a sawing device of the type mentioned in such a way that it has a structurally simpler and isunwidthen structure.
  • the first stop element comprises a stop angle with two angularly aligned stop legs, which receive a corner region of the workpieces between them, the stop angle pivotally held on the feed device and the pivot axis of the stop angle perpendicular is aligned to the feed direction and perpendicular to the saw line, and that on the saw carriage, a second stop element is positioned, to which the workpieces are applied laterally.
  • the workpieces to be split can be given a clear alignment with respect to the saw line, with the additional use of an adjustable plate-shaped Pad device can be omitted.
  • the invention provides that the second stop element is positioned on the saw carriage.
  • the saw carriage is mounted reproducibly movable on the machine frame along the saw line, and this movability is also used according to the present invention for the alignment of the second stop element.
  • the second stop element can predeterminarily take any position along the saw line.
  • the first stop element is arranged on the feed device, which is reproducibly back and forth transversely to the saw line.
  • the first stop element based on the feed direction in a predeterminable manner assume any position relative to the second stop element. Due to the mobility of the first and second stop members, the workpieces to be split can be oriented in any orientation with respect to the saw line by being applied to the stop members, which are positionable according to the desired saw cut.
  • the first stop element comprises a stop angle with two angularly aligned stop legs, which receive a corner portion of the workpieces between them, wherein the stop angle is pivotally supported on the feed device and the pivot axis of the stop angle is aligned perpendicular to the feed direction and perpendicular to the saw line. Due to the stop angle, the workpiece to be split can be given an unambiguous orientation relative to the first stop element by the workpiece facing away from the saw line Corner is applied to the two stop legs.
  • the stop angle is perpendicular to the feed direction and perpendicular to the saw line pivoted and can thus assume different orientations with respect to the saw line.
  • the second stop element may for example be designed as a stop pin, which can be inserted to align a workpiece to be split into a corresponding receptacle of the saw carriage. After alignment of the workpiece then the second stop element can be removed again from the saw carriage to then the workpiece To hold reliably by means of the hold-down device on the support table and to move the saw carriage to make the saw cut along the saw line.
  • the second stop element between a stop position in which it projects beyond a table level of the support table, and a release position in which it is positioned below the table level is movably held on the saw carriage.
  • the second stop element can thus be reciprocated in the vertical direction.
  • the saw carriage is moved along the saw line to a desired position and moves the second stop element in its stop position, so that the workpieces to be split can be applied laterally thereto.
  • the hold-down device can be actuated to hold the workpieces reliably, so that then the second stop element can be moved to its release position, without the risk that the orientation of the workpieces is changed.
  • the second stop element is thus held on the saw carriage, but it assumes a position below the table level of the support table, so that the splitting of the workpieces is not affected by the second stop element.
  • the vertical movement of the second stop element is done manually, for example by means of a hand crank. It is favorable, however, if the second stop element is associated with a motor drive device for moving the second stop element.
  • a motor drive device for example, an electric or pneumatic motor can be used.

  • the clamping devices are each assigned to a first stop element for detecting the workpieces in the region of the first stop elements. This ensures that the workpieces are reliably fixed to the first stop element. This makes it possible to carry out an oblique saw cut the feed device initially in a front, the saw line adjacent position to apply in this position, the workpieces to be split to the first stop element. The workpieces can then be detected by the associated clamping device, so that they are held immovably on the first stop element.
  • the feed device can be moved according to the length of the workpieces to be split backwards in a position spaced apart from the sawing line, wherein the workpieces are moved backwards.
  • the workpieces can be attached laterally Apply the arranged on the saw carriage second stop element, so that they occupy the desired orientation relative to the saw line.
  • clamping devices respectively assigned to a first stop element are held together with the respective first stop element so as to be pivotable about a pivot axis on the feed device, wherein the pivot axis is aligned perpendicular to the feed device and perpendicular to the saw line. Due to the pivotability of the first stop elements and the associated clamping devices, the alignment of the workpieces to be split is simplified.
  • the clamping devices are preferably configured like pliers and comprise at least one clamping jaw, which is rotatably supported about a rotational axis aligned perpendicular to the pivot axis of the clamping devices.
  • the clamping jaw is preferably coupled to a clamping cylinder, which can be acted upon by a pressure medium, for example compressed air, for detecting the workpieces to be split up.
  • the clamping jaw is designed as a two-armed lever, which can be applied with a first end to a workpiece and the second end is coupled to the clamping cylinder.
  • the application of the workpieces to be split on the first stop element is simplified in a preferred embodiment in that the first stop element is assigned a preferably plate-shaped ausgestaltetes support member for supporting the voltage applied to the first stop element region of the workpieces, wherein the workpieces between the support member and the associated clamping device can be clamped.
  • the support member thus serves, on the one hand, to support the workpieces to be split up; on the other hand, the support member forms an abutment for the clamping device, so that the workpieces can be clamped in the area of the first stop element between the clamping device and the support member.
  • the support member comprises a turntable on which the first stop element and the associated clamping device are held, wherein the turntable is held about a perpendicular to the feed direction and perpendicular to the saw axis aligned rotation axis of the feed device.
  • the first stop element and the clamping device can thus be aligned together by turning the turntable.
  • At least one stop leg of the first stop element is resiliently held. This makes it possible to align the two Anfordschwenkel acute angle to each other, so that even acute-angled corner portions of the workpieces to be split are reproducibly applied to the first stop element, the stop legs are so pivotable due to their resilient support that they can be pivoted in opposite directions to Recording, for example, rectangular aligned corner areas of the workpieces.
  • the resilient mounting of the stop leg can be done by means of a resilient element, for example by means of a leaf spring.
  • the clamping device associated with the first stop element detects the workpieces in the area between the two stop legs.
  • the sawing means comprises a control device with an input element for inputting the dimension of the workpieces to be split and the angle to take the saw cut relative to an edge of the workpieces, and with a Arithmetic unit for calculating position data for the first and second stop elements according to the input data for making the desired saw cut and that the first and second stop elements are positioned according to the calculated position data.
  • the user only has to refer to the dimension, that is to say the length and the width of the workpieces to be split, as well as the desired angle which the saw cut relates to on an edge of the workpieces should be entered.
  • the input can be made for example by means of a keyboard.
  • the computer unit calculates the required positions of the first and second stopper members, the position of the first stopper member being set by the distance from the sawing line, while the position of the second stopper member is defined by the distance from the first stopper member with respect to the sawing line.
  • the two stop elements can be positioned according to the calculated position data. By thus positioned stop elements, the orientation of the workpieces to be split is clearly specified, which can thus be divided into an easily manageable manner.
  • two plate-shaped workpieces are divided so that they can then be joined together at a predetermined angle.
  • projecting areas of the workpieces must be separated by making oblique to the longitudinal edges of the workpieces aligned saw cuts.
  • the required angle of the saw cuts relative to the longitudinal edges of the workpieces is dependent on what angle the two workpieces should then take each other and which width the respective workpieces have. If two workpieces of equal width are used, which are then to be aligned perpendicular to one another, the saw cut must be made at an angle of 45 ° to the longitudinal edges of the workpieces.
  • the angle of the saw cut with respect to a longitudinal edge of the workpiece is to be adapted to the corresponding widths.
  • the lengths and widths of the two workpieces and the angle to which the two workpieces should occupy each other are entered into the control device and that the stop elements by means of the control device the required saw cut are positioned accordingly.
