"Machine for edging of wood, plastic or the like, existing plates or panels, which with a Multi-drill is combined. "

The invention ¹ relates to a machine for edging made of wood, plastic or the like. Existing plates, panels or the like. Which is mounted on a stationary base, which in turn is firmly connected to a frame carrying the plate to be processed. Such a machine should ensure that there is an absolutely vertical position on all four plate sides and that all vertical and horizontal drill holes for accommodating the reference and fastening pins can be made on the same piece by means of a single arrangement process.

It is known for the edges of wood, plastic or the like. existing plates or panels and to make drill holes in the same machines where the trimming of the parallel pairs of sides takes place by means of a single cutting device, which is only available in works in a single direction, so that after the edge of a parallel pair of sides to the edge of the two-

ten and parallel to the first perpendicular Side pair is essential, the panel to be processed on the work surface at an angle of 90 to rotate, which entails a considerable loss of time and contains the risk that the two pairs of sides formed angle may not be 90 if you look at the plate to be processed after its Does not arrange rotation with the greatest possible accuracy. So far, as a result, the production of Machines are necessary that take up a relatively large amount of space, since the two dimensions of the work surface must be designed in such a way that they are not smaller than the maximum dimension of the ones to be machined Plates. Apart from the time and time required to rotate the disk, and therefore lost Manpower as well as the resulting risk, perhaps no perfectly edged pieces It is also essential to change the spacing of the work tools to avoid the edges of the to be able to pass over longer pairs of sides to trimming the shorter pair of sides or vice versa. In the according to the invention, on the other hand, the plate to be edged remains in one during the entire process stationary position, while in contrast a sliding frame in the longitudinal direction of the machine itself is moved along this plate. He carries two rotating, vertical pairs of saws, which are orthogonal to each other run, and one of which is intended to carry out the longitudinal cuts, while the other pair of saws the transverse cuts

executes. The first pair of saws also includes components to change the distance between the two saw blades, whereby the simultaneous Edging of the long sides is also made possible if the width of the piece to be edged changes.

The machine according to the invention is therefore demanding far less space than the already known machines of this type, because only their length of the maximum length of the panels to be processed is conditioned, while their width only to the predetermined maximum width the panels themselves and need not be sized to the worst possible dimension of the same, as this has been the case so far.

Thanks to the present invention, there is also the problem of the variable support in progress located plate is released, by means of bars that can be moved in the transverse direction, so that the edges of the plefcfce are always free and accessible to the tools, which is made possible by blocking them, which by means of a pneumatic system is made of suction cups that work with negative pressure, and their height and position are regulated can be so that the arrangement of the plate or panel can take place very quickly and accurately.

Invention ¹ enables the fact that it is rotatable about its own horizontal axis and can be moved upwards, downwards, forwards and backwards both without further and complicated handling and arrangement of the panel being processed, the working out more vertical and horizontal Drilled holes for accommodating the reference and fastening pins. According to the invention it is also provided that the rod carrying the spindles for the drilling, milling or similar tools is suspended in the machine for edging by two support arms and these arms are attached to the columns of the sliding frame carrying the two preceding pairs of saws. The boring bar can rotate around its own longitudinal axis on bolts and can be blocked at the desired working angle. In addition, it can also be moved up and down by means of two axes consisting of toothed racks and sliding in guide hubs, one such axis being provided for each of the two support arms.

It is obvious that the entire boring bar assembly goes together with the slidable and the saw blades supporting frame, with which it is firmly connected, can move forwards and backwards.

set, which must protrude from this bar nacli outside, so that the edge parts, which fall behind the edge and are cut away, protrude in relation to the two bars 4 and 4a. Between the bars 4 and 4a, pneumatic devices such as suction cups 7 for holding the panel to be edged are arranged, which work with negative pressure. When mounted on the machine, they enable the panel to be firmly locked by sucking on its lower side, but only in its central zone, so that the edges protruding from the joists 4 and 4a as well as the entire upper side of the panel are completely free for the passage of the working group.

The suction cups 7 can be cup-shaped or elastic.

th axis of their twin saw 10 can be approximated or removed from the same, components not shown in the drawing being provided for blocking the saw 10a in the preselected position. The disk-shaped saw pairs 10, 10a and 11, 11a are connected to actuating motors 13 »13 ^> or Ik , which comprise means for control.

The second pair of disc-shaped saws 11 and 11a, whose Working surfaces perpendicular to the vertical longitudinal plane of the Machine run, is carried by a carriage 15, which, in turn, is mounted on the crossbar 8a of the frame 8, along which, when the handle 17 is operated is slidable. The two disc-shaped or leaf-shaped Saws 11 and 11a are on the sides of the vertical and arranged through the axes of the other pair of rotating saws 10 and 10a through plane.

The multiple drilling machine in turn consists of a prismatic, strongly elongated box, ie of a so-called rod 20 which carries a number of hammer spindles 21 and is carried by a pierced bolt 22 at each end. The two bolts 22 can rotate in two carriers 23 and 23a, which are carried by two vertical axes 2k and 24a, which in turn can be slid in two guide hubs 27 by means of a handwheel 25 and a push rod 26 operated racks. The two guide hubs 27 are included in the arms 28, which with the posts 8b of the

Frame 8 are firmly connected, and which the task falls to carry the entire drilling group and this in a single machine with the above device for edging, carrying and blocking, to unite.

The rack Zh for the vertical movement comprises a system of rings and screws 29 for adjusting the barrel, while the rotation of the rod 20 about the bolts 22 is controlled by a dividing head 30, which can eimüimen four positions in the illustrated machine and with levers 30a and blocking systems 30b.

The movement of the hammer spindles 21 carrying the tools is controlled by a mechanism of chains (e.g. by a roller chain) and gears ensured, the whole being housed in the drill rod 20 and through actuated through the pierced bolt 22 by the motor 3I will.

The supports 23 and 23a are both in the form of a bottom a cam formed projection, in which projections the axis of a ball bearing 32 in the horizontal direction is inserted. As the vertical movement takes place, these ball bearings load the weight of the drill on two rods 33, which in turn are connected to the columns 8b of the frame 8 by hinges and are held in equilibrium by the counterweight 3 ^ · so that the relevant process itself can be

Reduction of the applied force is facilitated.

The operation of the machine for edging combined with the multiple drilling machine is as follows:

The first thing to do is to set the correct distance between the joists 4 and 4a by adapting it to the width of the panel to be processed, while at the same time moving the group of movable saws 10a around it to the appropriate distance from the stationary one To bring saw 10 so that the two saws 10 and 10a are able to edge the panel in question in the desired width. End stops 19 are provided which can be fastened in predetermined positions with respect to the rails 2 and which regulate the length of the working group in relation to the length which the panel to be edged must have. Then the plate is placed in the appropriate position on the longitudinal beams 4 and 4a. After the height and position of the suction cups or the like 7 has been set, they are connected to the vacuum source. In this way, the plate remains firmly blocked to the base 1 of the machine.

The first step of edging or trimming then takes place in that the saw 11 and 11a set in rotation Motor 14 is started and the movable carriage 15 », which carries the saws, into the vertical Direction shifted to the vertical longitudinal plane of the machine.

After the first side of the plate has been folded (in the example shown, the left side), it moves one the carriage 15 on one side of the frame, so that this can no longer touch the plate, after which the motors 13 and 13a are started, which then the operate other rotating saw pairs 10 and 10a while the group is slowly moved along with the handwheel 9 of the rails 2 can slide, in this way, the longitudinal sides of the or is being processed Edging of the plate or panels.

At the end of the run, motors 13 and Λ3 &. switched off and the motor 14 of the group comprising the saws 11 and 11a started again, the carriage 15 of this group being slowly pushed along the rail 8a so that the other, transverse cut is made (right-hand side).

On the basis of the above it can be seen that the working saw is the saw 11, while the other Saw rotates empty, d. i.e., moves but does not work. As a result, the maximum length of the finished machined plate is the same as that in the end-of-travel positions or left and right of the working group between the level of the saw 11a and that of the saw 11 existing Be spaced as illustrated in FIG. It should be noted here that, in individual cases, the circumcision process if necessary, it can also be omitted or started later or at the back.

Then we move on to the production of the vertical and horizontal drill holes, but the plate or panel being processed remains in the position in which it was attached at the beginning of the process. After the appropriate tools, e.g. B. the tools 21 ^f , have been mounted in the various hammer spindles 21 of the drill rod 20, one moves the frame 8 along the

2
Longitudinal rails, blocking it in the desired places, which usually happens near the transverse wheels (sides). The tools are then brought into a vertical position by actuating the dividing head 30 accordingly by means of the lever 30a and the blocking lever 30b, after which the motor 31 is put into operation and the rod 20 is lowered by actuating the handwheel 25. As soon as the tools arranged in advance in the desired number penetrate into the plate or panel being processed, they simultaneously execute all vertical drill holes along the previously selected, transverse array, which are both continuous and in their Depth permitted by the barrel control system 29. If one wishes to produce further vertical drill holes along other, transversely extending rows, the above operations must be repeated, namely after having arranged for the displacement of the frame 8 at the level of each desired row.

However, every time you want to change the number, the quality or the dimensions of the tools, you have to Motor 31 must necessarily be stopped.

To produce the horizontal drill holes, which operation ^{1 can} only be carried out on the head sides of the plate or panel being processed, the frame 8 must be moved outside one of the two head sides j then the tools are moved by means of the levers 30a and 30b arranged in a horizontal position. The height of the tools is now set, always by means of the device 29 ', so that their axis is at the same height as the axis of the borehole to be made, and the motor 31 is then started. The horizontal drill hole or holes prepared in this way are obtained by pushing the frame 8 against the head side or letting it advance in the direction of said head side to the desired depth, which cannot be more than the length of the tool, and which is also adjustable by the components 19 for regulation and stopping. The same process must, if necessary, be repeated on the opposite side of the head or if it is desired to produce rows of boreholes at different heights in the same head side.
