Description

25th

The invention relates to a method according to the preamble of the patent claim.

In known methods (DE-GM 73 13 701, AT-PS 3 12 249) is worked so that the slide the fed boards from its starting position pushed into the pressing station and after pressing to Eject again from this. While these procedural steps were taking place, no new ones could be made Boards are fed because the slide had not yet returned to its original position. Only when the The slide was moved back to its starting position after ejection, new boards could be fed will. As long as the new boards were being fed in, the press station was empty. She didn't work.

The invention is now based on the object of providing an "o To create a method of the type mentioned, through which the supply of new boards essentially is made independent of the position of the slide and thus leads to an increase in performance.

This object is achieved by the characterizing part of the patent claim.

According to the invention, the feeding of the boards, the process in the pressing station, and the pressing are superimposed itself and ejecting. It is possible immediately after stripping the strand from the sun Top of the slide with the supply of new boards to compose a new strand kick off. This is from the further movement of the slide into and out of the press station completely independent since. the slider moves under the boards and the boards on the The top of the slide. When the slide moves back, the and compiled strand on the press table. When the slide is then pushed forward again, it takes it that way put together a strand and immediately a new strand can be put together on the top of the slide will. The fact that the various movements are superimposed makes a considerable one Performance increase achieved

The invention is explained in more detail below with reference to the drawing. It shows

i · i g. 1 shows a plan view of a device for carrying out the method; and

2 shows a side view of the device according to FIG. 1, rotated by 90 °

The illustrated device consists of a stationary press table 13 to which a pressure beam 10 is attached is assigned to the pressure bar 10, a stop 12 is attached. The press station is still by a Printing cylinder 8 and a counter-pressure part 9 for setting the end positions and for Compression formed in the longitudinal direction

Upstream of the press station is a feed station, which is formed by side guides 2, 3 of where the side guide 2 is adjustable to adjust to different wood widths Different Board cross-sections are shown in phantom in Fig. 2. The feed station is through a Feed apparatus 4 and an end stop 7 completed in connection with the feed apparatus 4 is a Chop saw 6 is provided, which is indicated by a dash-dotted line in the plan view of FIG. 1 is indicated.

Under the feed station and the press station to into an ejecting station is above the press table 13 a slide 1 can be moved back and forth. The three most important positions of the slide 1 are marked with I. (Starting position), II (pressing position) and III (ejecting position).

The device works in such a way that the finger-jointed boards 5 are introduced into the feed station by the feed apparatus 4 in different lengths will. They lie between the side guides 2, 3 and on the slide 1.

When the strand reaches the end stop 7, a generates a corresponding signal, and the cross-cut saw 6 cuts the strand at the appropriate point. The slide 1, which is now moving to position I, now strips the strand onto the press table 13, so that the latter now under the side guide 3 raised to wood thickness on the press table 13 in the Position! I, d. H. can be pushed into the PrePstation below the pressure bar 10.

Immediately after the strand has been pushed out of the area of the feed station, the Feeding of new boards 5 by the feed apparatus 4 can be started. Here is a corresponding Relative movement between the beds 5 and the slide 1 instead, but this is not a hindrance. While of the continuous feeding of the boards 5 by the feed device 4, the pusher 1 then moves in Position III for ejecting the boards pressed in the pressing station 5.

The slide 1 can now be withdrawn into position I in its starting position. A new The strand has already been introduced into the feed station and assembled. If the slide 1 the Has reached position 1, the assembled boards 5 fall on the press table 13 and the above The process described can be repeated.

Claims (1)

Claim: Process for the longitudinal pressing of finger-jointed boards with variable cross-sections and different ones Entrance lengths in which a slide rests against one another at the finger-jointed joints fed into a strand assembled boards perpendicular to this feed direction supplies a press station via a press table and, after pressing, ejects it therefrom, thereby characterized in that the boards (5) are fed and collated on top of the slide (1) be that the boards (5) when retracting the slide (1) from its top be stripped and fall on the press table (13) and when driving from its front side of the Preßstatiön fed and ejected from this and that during the feeding and the Eject on the top of the slide (1) again boards (5) and fed into a strand be put together.
