EQUIPMENT FOR CAREER WORKING IN A WOOD PIECE

The invention relates to an apparatus according to the preamble of claim 1.

5

The devices according to the object of the invention, i.e. the so-called lathes are mainly used for milling grooves substantially transverse to the longitudinal direction of the log for latch joints used in a log building. Known lathes typically have two machining units that move perpendicular to each other. One of the machining units usually moves in the horizontal direction and the other in the vertical direction. Each machining unit usually has two blade units that simultaneously mill grooves on opposite sides of the log being processed. In known lathes, the blade settings of the blade units are made by means of snacks, unpacking and assembling the blade packages. The setting time takes a long time. In machining a log, the log is moved step by step. Once the latch is made, the operator has to manually move the log first to 20 cuts and then to drilling. The movements of the blade units are reciprocating. It takes a lot of time and the work is difficult to automate.

The object of the present invention is to provide a completely new type of latch machine which avoids the disadvantages of the prior art.

The invention is characterized by what is stated in the claims.

The apparatus according to the invention has a number of significant advantages. In one cycle of the device, the grooves required in the log construction can be machined into a planed log and the log is cut to a suitable length. The time required to process the log has thus been significantly reduced. The proportion of manual work steps 35 has been substantially reduced. By arranging several machining units in a slide frame which moves with the pivot body and pivots, a very efficient operation of the equipment is made possible. By arranging the machining width adjustment in the machining units, very fast setting times are achieved when the machining width changes. By arranging the machining units inside the slide frame 5 for protection, work safety has also been improved.

In the following, the invention will be described with reference to the accompanying drawings, in which Figures 1-5 show a device according to the invention in a simplified manner in different stages when viewed in the feed direction of a piece of wood,

Figures 6-10 show a simplified view of an apparatus 15 according to the invention in different stages, and

Figure 11 shows a slide body of an apparatus according to the invention.

The apparatus according to the invention for machining at least one groove substantially transverse to the longitudinal direction in an elongate piece of wood 1, in particular for machining grooves in a latch joint in a log, comprises bodies 2 and 25 of at least one machining unit 5,6,7,8, the blade end being arranged direction. The body 2 is provided with a pivot body 3, preferably in a plane substantially transverse to the longitudinal axis of the piece of wood 1, pivotally arranged on the pivot body 3, in which at least one machining unit 5, 6, 7, 8 is arranged. in the embodiment according to claim 1 is arranged to pivot about a horizontal axis, which horizontal axis is preferably parallel to the longitudinal axis of the body 1 to be treated or its tangent thereto.

101273 3 The pivot body 3 is circumferential, whereby the piece of wood 1 can be inserted through an opening inside the circumference of the pivot body.

The pivot body 3 is provided with, for example, a pivot ring in which the counter members 16 in the body are arranged so that the pivot body can be pivoted. The counter members 16 may be, for example, rollers, for example one of which is in contact with the inner surface of the pivot ring and at least two in contact with the outer surface of the pivot ring. The body 3 of the pivot-10 is thus arranged to be pivotable on the roller members 16. The means required for turning the pivot body can be any means for enabling pivoting movement, such as various bearing means or, for example, gear-to-gear combinations. For example, the pivot body is pivoted by rotating at least one of the roller members or the like. The pivot body can also be pivoted, for example, by means of a cylinder-piston combination and the above-mentioned roller members.

The slide body 4 is arranged in the pivot body 3, for example, to be moved on the lines 15. The slide body 4 can thus be moved by means of the movement device 13, 14 even back in the pivot body 3. The slide body 4 is preferably arranged to comprise two subframes with an opening between them. The subframes of the slide frame are arranged so that the piece of wood 1 to be treated is between the subframes. Machining units 5, 6, 7, 8 are arranged on the slide frame 4 on opposite sides of the piece of wood 1 to be treated. In the example of the figures, the machining units are arranged in subframes. The drive body 9, 10 of the machining units 5, 6, 7, 8 is also arranged on the slide body. The working depth can be adjusted by moving the subframes, preferably in the direction of the vertical axis towards or away from each other.

101273 4

In addition, the slide body 4 is preferably also provided with at least one device 11/12 for cutting the piece of wood to be treated. The cutting device is most preferably a circular saw 11/12. There are preferably two circular saws located in the longitudinal direction of the piece of wood 5 to be treated on opposite sides of the machining units 5, 6. The cutting devices 11, 12 are operated by a drive device, which is preferably a drive device for the machining units.

The machining units 5, 6, 7, 8 are arranged at least two in succession in the direction of movement of the slide body 4. In this case, by moving in one direction of the slide body, several grooves can be provided in the body 1 to be treated, as will be explained below. The machining units are preferably arranged symmetrically.

The processing units 5, 6, 7, 8 are provided with an adjustment device for adjusting the working width. The machining unit 5, 6, 7, 8 comprises at least two milling blades 18, 19 which are movable in the axial direction of the axis of rotation 21 of the machining unit and can be arranged at least partially interleaved with one another. To adjust the machining width, adjusting arms 22, 23 connected to the milling cutter are provided, which are provided with an adjusting member, preferably an adjusting screw 24. By turning the adjusting screw, the nut members in which the adjusting arms are arranged are moved. In this case, the position of the milling cutters of the 25 machining units on the axis of rotation changes and thus also the machining width changes. In the embodiment of Fig. 11, each machining unit comprises three milling blades 18, 19, 20, the middle 20 of which is fixed and the position of the blades 18, 19 on opposite sides on the shaft 21 is adjusted. 30 hardware. In addition, the control of the switching device 11, 12 can be connected to the control device. In this case, when the machining width changes, for example, the distance of the cutting point from the edge of the groove to be machined can be kept constant. In the case of Fig. 11, the support arms of the cutting device are mounted on the sleeves of the movable milling cutters 35, whereby when the blades are moved by the adjusting arms, the support arms of the cutting equipment move with the milling cutters.

The slide body moving apparatus 13, 14 consists of a cylinder-piston assembly 13, 14. The cylinder-piston assembly is arranged to pivot with the pivot body, preferably parallel to the direction of movement of the slide body. The piston rod 14 is arranged in the slide body. The cylinder-piston combination is operated with a pressure medium, whereby the piston rod 14 10 protrudes outwards and the slide body moves from the step of Fig. 1 to the step of Fig. 2. Furthermore, the slide body moves by means of the drive equipment up to step 5. The slide body can be moved by any known movement arrangement.

The apparatus according to the invention operates as follows:

Figures 1 and 6 show an initial situation in which a cross section of the piece of wood 1 to be processed is shown. The slide body 4 is shown in its extreme position on the left. The piece of wood 1 is arranged on a substrate not shown in the simplified figure 20.

Fig. 7 shows the next step in which the slide body 4 has moved to the right from the situation according to Fig. 1. At this stage, the workpiece 1 to be treated is cut with the cutting device 11, 12 of the apparatus, which is preferably a circular saw.

Fig. 8 shows the machining step following the cutting, in which the upper and lower surfaces of the body to be treated 1 are machined with the first machining units 5, 6 in the slide body 4.

\ 30

Figures 2 and 9 show a step in which the slide body 4 has moved to a second position in which the body 1 to be treated is in the direction of movement of the slide body between the first machining units 5, 6 and the second machining units 7, 8.

35 101273 6

Figure 3 shows the turning step of the turning body 3. There, the pivot body is pivoted on the roller members 16 in the body 2, preferably about 90 °. In this case, the slide body 4 arranged in the pivot frame by means of guides also pivots with the pivot body 3.

The end of the slide body 4 on the right in Fig. 2 has turned to the position according to Fig. 4, where it is at the top. The work units have thus moved to the side walls of the part in question. The pivot body 3 pivots approximately about the longitudinal axis of the piece of wood 1 to be treated or its axis 10. The second machining units 7, 8 are below the workpiece 1 to be treated and the first machining units 5, 6 are above the workpiece 1 to be treated. In the next step, the slide body 4 is moved to the step of Fig. 5, whereby the second machining units machine the grooves in the side surfaces of the body 15 to be treated.

The workpiece 1 is then moved forward by the desired distance and the corresponding grooves are made in the workpiece in the reverse order.

20

Finally, the piece is cut with cutting equipment. As described above, for example, a planed log can be made with the necessary grooves in a log building (so-called latch grooves and wind-corner oats) for a latch connection.

25

In addition, a separate drilling unit (not shown in the figures) can be connected to the equipment, which drills any holes that may be needed in the workpiece during machining operations. Such holes are the so-called naakelireiät.

In addition, the entire hardware can be rotated about a vertical axis. In the figures, the body 2 is arranged to pivot about the bearing member 25. The angle of rotation can be, for example, ± 45 °. The body 35 can be turned by hand or by means of a turning device, such as a cylinder-piston unit 101273 7. When the workpiece remains in place, the pivoting of the frame allows the machining of grooves other than the transverse grooves perpendicular to the longitudinal axis of the piece of wood. In this case, it is also possible to make grooves for the joints required, for example, in the construction of log-5 in bay windows or, for example, in hexagonal buildings.

It will be clear to a person skilled in the art that the invention is not limited to the examples given above, but can be varied within the scope of the appended claims. Thus, the slide body may comprise several machining units.
