Description

PANEL CUTTING SAW WITH ANGLE-ADJUSTABLE PLANT

The invention relates to a processing device as described in the preamble of claim 1.

Machining devices for plate-shaped workpieces known from the prior art are provided with a feed device for the workpieces, which also forms or has a stop device and clamping device. The workpieces can thus be clamped and corresponding to the cutting line for making cuts parallel to a cutting line running parallel to a plate side surface abutting the stop

Dimensions are adjusted. Basically, panels can thus be divided, the sections having side surfaces which are oriented at right angles to one another. If panel blanks with side surfaces that run at an angle to one another are to be produced on such processing devices, the panels must be set up manually with respect to the saw line.

The object of the invention is to provide a processing device with which a rapid positioning of plate-shaped workpieces for making cutting lines running at an angle to one another is achieved.

This object of the invention is achieved by the characterizing features of claim 1. The surprising advantage here is that at the same time as the adjustment of a table-shaped support device which supports a workpiece over the entire surface in a position to be provided for an angular cut, the intended angular position of a contact device on which the workpiece is to be placed with one of its side faces, is achieved.

An embodiment according to claim 2 is possible, whereby a two-point system is achieved and any inaccuracies on the side surface of the workpiece have no influence on the setting of the angular direction.

Formations according to claims 3 to 5 are advantageous because this enables the machining device to be quickly retrofitted for the various manufacturing processes to be carried out on workpieces.

However, training according to claims 6 and 7 is also possible, because flat system for the side surface of the workpiece is reached.

However, designs according to claims 8 to 12 are also advantageous, as a result of which the processing device can be equipped with standard components in accordance with the intended use with a corresponding adjusting device for exact positioning for making angular cuts. This also offers the possibility of manual adjustment of such a device and automatic adjustment via the control device provided with such a device.

As a result of the advantageous further development, as described in claim 13, a reference line is reached through a stop surface of a stop bar, by means of which the workpiece is positioned in relation to a workpiece corner or side surface and the reference position can be used to further optimize the cutting processes.

Another advantage are the training according to claims 14 and 15, whereby the

Position of the support device and thus a certain angular position of the contact device with respect to the cutting plane of the sawing device can be determined and monitored.

An embodiment according to claim 16 is also possible, whereby an adjustment process of the support device via the control device, e.g. just by entering the required

Angular values for the angular position of the cutting line must be entered and the adjustment process runs automatically.

According to the advantageous developments, as described in claims 17 and 18, a very exact guidance is achieved for the support device that is adjustable relative to the machine frame or support table.

Finally, an embodiment according to claim 19 is also advantageous, as a result of which a set position can be fixed if e.g. series of workpieces are to be machined in this position setting.

For a better understanding of the invention, this will be explained in more detail using the exemplary embodiments shown in the figures.

As an introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally etc. refer to the figure described and illustrated immediately and are to be transferred to the new position in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 and 2, a processing device 1, in particular panel sizing saw 2, for panel-shaped workpieces 3 is shown. A machine frame 4 forms a table-shaped support surface 5 for the workpieces 3 to be machined. On opposite end faces of the machine frame 4, pressure beam towers 6, which are formed by profiles and extend in the vertical direction and project beyond the support surface 5, are arranged. These support a pressure beam 8 of a clamping device 9, which is adjustable in guide arrangements 7 in the direction perpendicular to the support surface 5, which is formed by an approximately C-shaped profile 10 and which has a slot-shaped opening 11 facing the support surface 5. Adjustment drives 13, for example pressurized cylinders 14, are arranged on the pressure beam towers 6 via support bearings 12 for the adjustment of the pressure beam 8 and are connected to it in motion via piston rods 15. Of course, spindle drives, linear motor drives, etc., which are operated by an electric motor, are also possible as adjusting drives 13 for the pressure beam 8.

In the area between the support surface 5 and a contact surface 16 in the machine frame 4 there is a known and not described machining device 17 for the workpieces 3, such as e.g. a sawing device 18, milling device, etc., which can be moved in longitudinal guides via adjusting drives 13, is arranged, the preferred adjustment during the machining process taking place in the direction of the longitudinal extension of the pressure beam 8 and a slot-shaped recess in the table-shaped support surface 5 for the passage of a tool 19, eg Circular saw blade, is arranged.

The machine frame 4 furthermore has guide arrangements 20 for a transport slide 21 which projects beyond the support surface 5 and can be adjusted in the direction perpendicular to the longitudinal extension of the pressure beam 8 by means of a drive device.

At least one clamping device 22 is arranged on the transport slide 21, which is formed by collets 23 for the workpiece 3 which are spaced apart in the direction of the longitudinal extent of the pressure beam 8 and project beyond the transport slide 21 in the direction of the pressure beam 8. The collets 23 are e.g. actuated via pressurized clamping cylinder 24. An automatic operation of the clamping device 22 is thus fixed in terms of movement

The workpiece 3 can be picked up in order to adjust it according to a predetermined movement sequence of the transport slide 21 on the support surface 5.

The collets 23 on the transport slide 21 at the same time form a stop arrangement 25 in order to surround the workpieces 3 with side surfaces 26 parallel to a cutting plane 27

To position the sawing device 18 and to move according to dimensional inputs stored in a control device 28 in order to carry out successive cuts. The transport slide 21 thus forms a feed device 29 with which, in connection with the stop arrangement 25, cuts can be made which run at right angles to one another for the production of partial pieces from the workpiece 3.

2, table-shaped support devices 31 for supporting a workpiece 3 are provided on the front side of a support table 30 formed by the machine frame 4 and form a support surface 32 which extends at the same level as a support surface 33 of the support table 30. The support devices 31 are after a preferred embodiment provided with air outlet nozzles 34, which are supplied with compressed air by a pressure supply device 35 and form an air cushion between the support surface 32 and the workpiece 3, as a result of which it is very easy to manipulate.

The support devices 31 are adjustably mounted on the machine frame 4 in a direction running parallel to the cutting plane 27, at least one of the support devices 31 being motor-adjustable in a guide arrangement 37 running parallel to the cutting plane 27 by means of a drive device 36 which is connected to the control device 28 is. Various linear drives are suitable as drive device 36, e.g. Spindle drives, electric traveling field drives etc.

In the exemplary embodiment shown, the drive device 36 is formed by a chain drive 38, in which a chain 39 forms an endless strand 40 for a drive means 41. A drive motor 42 of the chain drive 38 is e.g. by an electric motor, e.g. a stepper motor 43, whereby a positioning drive for the adjustment of the support device 31 is achieved. Of course, other drive devices 36 known from the prior art, such as e.g. a rack arranged on the machine frame 4 is possible, into which a pinion of a drive motor connected to the support device 31 so as to be fixed in motion engages. Other options are the use of a toothed belt drive or a cable drive. It is also possible to use a threaded spindle, e.g. is rotatably mounted on the machine frame 4 and is driven by a drive motor which engages with a threaded sleeve arranged on the support device 31.

A contact device 44 for the side surfaces 26 of the workpiece 3 is now further formed by stop elements 45, of which at least one stop element 45 is provided on the support device 31 and a further stop element 45 on the support table 33. The stop elements 45 are preferably adjustable in the direction perpendicular to the support surfaces 32, 33, these being sunk in a first position in the support table 30 and the support device 31 and projecting beyond the support surfaces 32, 33 in a second position, so that the workpiece 3 to be able to bring these stop elements 45 into contact with one of its side surfaces 26.

Due to the possibility of adjustment of the support device 31 provided with the stop element 45 of the contact device 44 - according to the double arrow 46 - that is to the cutting plane 27 parallel direction and further, on the support table 30 assuming a fixed position stop element 45, an adjustable side surface position to the cutting plane 27 is achieved.

A measuring device 47 is preferably connected to the control device 28, by means of which the adjustment of the support device 31 is determined, displayed or controlled, which further makes it possible to use the drive device 36 as a manual drive, e.g. Form a threaded spindle and to carry out the adjustment on a predetermined adjustment path by means of the display of the measuring device 47 in order to set a predetermined angle 48 between the cutting plane 27 and one of the side surfaces 26, in particular longitudinal side surfaces.

A maximum adjustment path of the support device 31 in the direction of the double arrow 46 is preferred for setting the angle 48 from 45 ° in each case, starting from a center position in which one of the side surfaces 26, in particular longitudinal side surfaces, to the cutting plane

27 runs at right angles.

According to a further preferred embodiment - as can be seen in FIG. 2 - stop strips 49, which run parallel to the cutting plane 27 and to the cutting plane 27, are arranged on the feed device 29 between the collets 23, which form a reference position for a workpiece edge 50 and by means of which an exact Setting the triangular, trapezoidal, polygonal sections having a predetermined height can be produced.

3 and 4, a detail of the processing device 1 according to the invention with the adjustable support device 31 and the contact device 44 is shown in a sectional view and a plan view. The guide arrangement 37 and the drive device 36 with the chain drive 38 can also be seen from these representations. A pneumatic cylinder 52, which can be acted upon with a pressure medium, for example compressed air, is fastened to an underside 51 of the fixed support table 30. When the pneumatic cylinder 52 is acted upon by the pressure medium, an actuator 53 projects beyond the support surface 33 and thus forms one of the stop elements 45. A similar design and arrangement is given for the further stop element 45 on the adjustable support device 31. A simplified embodiment provides, for example, instead of an adjustable stop element 45 on the support table 30, a fixed bolt which can be inserted into a bore and which, depending on the need, on Support table can be provided.

The actuators 53 can be directly piston rods of the pneumatic cylinder 52 or independent bolt-shaped elements which are motionally connected to the piston rod of the pneumatic cylinder 52.

It is still noted that, of course, instead of the pneumatic cylinders 52, i.e. the application of compressed air, hydraulic cylinders, but also electrically, e.g. actuators based on magnetic effect can be used.

The support device 31 is supported on the machine frame 4 by means of the guide arrangement 37, a guide rail 54 running parallel to the cutting plane 27 being fastened to the machine frame 4. At least one slide block 57 receiving the guide rail 54 in a receiving groove 56 is arranged on an underside 55 of the support device 31. This is the guidance of the support device 31 in a tilt-free manner and in

Cutting plane 27 ensures parallel direction.

Deflection wheels 60, 61 for the chain 39 of the chain drive 38 are arranged on opposite guide regions 58, 59 on the guide rail. The support device 31 is connected to the chain 39 via a connecting device 62. In the exemplary embodiment shown for a manual adjustment of the support device 31, the chain drive 38 can be adjusted by means of a handwheel 63 which is non-rotatably coupled to one of the deflection wheels 60, 61.

In the central position of the support device 31 shown in FIG. 4, the stop elements 45 form a stop plane 64 running perpendicular to the cutting plane 27. In order to achieve a cutting line running at an angle to one of the side surfaces 26 of the workpiece 3, for example for producing so-called miter cuts, the support device 31 is made in accordance with the double arrow 46, starting from the central position - i.e. the right-angled contact plane 64 - in the opposite direction from the central position in accordance with the predetermined angular position Adjusted directions. If a certain angle is specified for producing, for example, a miter cut, an adjustment path 65 of the stop element 45 adjustable with the support device 31 arises arithmetically on the basis of the normal distance 66 between the stop elements 45, which is machine-related and known. If the angle function is now stored in a computer module 67 of the control device 28, the adjustment path 65 required for this can be entered immediately after entering a desired angle. shows and are automatically covered with the drive device 36 designed as a positioning drive or can be set manually by means of the handwheel 63 and the display of the measuring device 47, that is to say that the contact plane 64 is at a predetermined angular extent approximately between +/- 5 ° and 90 ° angular to right-angled is adjustable to the cutting plane 27 and runs at right angles to the support surface 32, 33.

5 shows a further embodiment of the contact device 44 for a side surface 26 of the workpiece 3 in the machining device 1 according to the invention. In this embodiment, a bolt 68 projecting beyond the support surface 33 is arranged on the support table 30 of the machining device 1, approximately on the average over a total length, can be inserted into a bore 69 of the support table 30 if necessary. On the drive device 36, e.g. the chain drive 38, in the direction of the double arrow 46 adjustably arranged support device 31, a further pin 70 can be used to project the support surface 32. The contact device 44 also has a contact ruler 71, which is pivotably mounted with a bore 69 on the bolt 68 of the support table 33. Furthermore, the contact ruler 71 has a slot 72 in the longitudinal direction of the contact ruler 71 for receiving the bolt 70 arranged in the support device 31. This thus forms a link guide, in which the contact ruler 71 via the bolt 70 when the support device 31 is adjusted, e.g. from the position drawn in full lines to the position shown in dashed lines, is also pivoted and the resulting relative movement between the contact ruler 71 and the bolt 70 can take place.

Of course, instead of the insertable bolt 68 of the support table 30, a bearing journal which is fixedly connected to the contact ruler 71 and which pivotally supports the contact ruler 71 in the bore 69 of the support table 30 is also possible. The formation of the contact device 44 with the contact ruler 71 results in a continuous contact surface 73 for the side surface 26, in particular the longitudinal side surface, of the workpiece 3 and thus an exact contact.

As can also be seen, the stop arrangement 25 which can be moved with the feed device 29 for contacting the workpiece edge 50 forms, for example, a reference setting for a distance 74 from the cutting plane 27 in order to provide the workpiece 3 with a miter cut, for example, with the least possible waste. The distance 74 also acts from the computer module provided in the control device 28 as a function of the angle dimension for the angle 48 and, for example, a width 75 of the workpiece 3 or a cutting length 76 of the miter cut and automatically set by means of the movable feed device 29.

For the sake of order, it should finally be pointed out that, for better understanding of the processing device 1, these or their components have been partially shown to scale and / or enlarged and / or reduced.

The object on which the independent inventive solutions are based can be found in the description.

Above all, the individual in FIGS. 1, 2; 3, 4; 5 shown designs and measures form the subject of independent, inventive solutions. The relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
