Method of using a machine tool and a folding machine

The present invention relates to a method of operating a machining device such as a field saw 5 or the like, comprising a body provided with a substantially elongated support surface such as a roll plane or the like for machining parts such as logs or the like, machining means such as - means, such as wheels or the like, for enabling the saw to move on the base, and support means, such as height-adjustable legs or the like, to support the body, particularly in the operating position of the machine tool. The machining device is arranged to be assembled for readiness, transport and / or the like by forming a body thereof in a central part, along which, preferably at its opposite ends, extensions are arranged which are moved substantially horizontally to bring them to the side of the central part.

: * · *: Finnish Patent No. 80624 discloses the corresponding • · · · * · *; but a suitable longitudinally extending field saw, consisting of a fixed center frame and a ···· .... · extension near the joint. lifting device for raising and lowering the extension.

• · I "When the extension unit is in use, it is lifted from the center end of the center frame by means of a lifting device and 30 is further moved longitudinally of the field saw ···: in the support of the lifting device to the storage and transport center. and above the table therein:. *. Similarly, the extension is moved from the storage and · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · above above the center frame and table. ·: Si.

118524 2 The solution disclosed herein is specifically intended to enable the field saw to be deployed and unloaded, respectively, in the smallest possible space by lowering / raising 5 extensions relative to the fixed center of the frame. However, this necessitates the use of special lifting device arrangements for moving the extension piece, which makes the device solution, firstly, very complicated in design and difficult to operate. When forming that. further extending the solution of the plurality of parts, a longitudinally-articulated construction of two or more successive positions is obtained, which does not provide the best possible stability. In this way, of course, it is possible to minimize the weight of the structures that can be lifted one at a time, but at the same time complicates its use and jeopardizes its stability. In addition, when moving each extension piece in the height direction, special attention must be paid to occupational safety so as to prevent accidentally dripping and causing injury to the movable extension piece with respect to the fixed center section.

: ': Therefore, this solution in practice does not bring: ***: a significant improvement in that context, nor does it .Ϊ. 25 as such is not satisfactory especially with regard to occupational safety * ···.

• · ·· · • · ♦ · I !! Instead, it is already known in the prior art to implement, for example, a field saw 30 of the type described above, such that the extensions therein are articulated ··· ··.! to the fixed center frame so that they can be folded * »· · ... · longitudinally to the side of the center frame. The problem with these types of field saws is that the foldable sides · · · ··· ·. ···. • · · * 35 can not be used in confined spaces because it requires a lot of space around to make the saw ready for use. As such, moving the extension pieces horizontally is a much better solution, especially in the field of labor safety, than raising and lowering them vertically.

The purpose of the method 5 of the present invention is to provide a decisive improvement on the above problems and thus to substantially increase the state of the art. To accomplish this purpose, the method according to the invention is essentially characterized in that the body 10 is assembled from a position of use of the machining device by a substantially horizontal pivoting arm arrangement which initially moves the extension member outwardly from the center portion to substantially parallel to the transverse to a position adjacent the center portion and thereafter further inwardly inward along the center portion.

The most important advantages of the method according to the invention are its simplicity and reliability. In addition, the method according to the invention · · · ί * ^ 1 enables an optimal solution, especially in the field of occupational safety, because · !. First of all, the included extension pieces do not need to be moved * ·· * la vertically, but they can be moved with very little horizontal force. In this connection, a preferred embodiment of the method further utilizes a movable, such as articulated, hinged, and / or articulated arm system, which is movable, such as articulated, hinged, to its central and extension 30 ends, consisting of at least two •; * · pivot arms pivotally attached to each other, f ·· ·. ···, in the operating position of the implement in a slight ··· * φ> · # 35 angular position with respect to each other. In this case, the machine • · «ί · * can be folded out of its operating position by simply • aa · · ... · first by pulling the extension outwards to straighten and release the extension pieces from the center 118524 4, after which the extension can be pushed forward as described in parallel to and parallel to the center section and thereafter longitudinally retracts back to the center section and locks therein.

Advantageous embodiments of the method of the invention are set forth in the dependent claims.

The invention also relates to a collapsible machining device operating according to the method, which is described in more detail in the preamble of the independent claim therein. The features of the machining device 15 are described in the characterizing part of the independent claim therein.

The most important advantages of the machining device according to the invention are its simplicity in construction and use. First of all, the machining device according to the invention makes it possible to significantly improve occupational safety in relation to the present ones, since all the assembly operations which are carried out on it can be carried out without its excessive force by moving its extension parts substantially horizontally. In a preferred embodiment, this is · · implemented at its opposite ends in the central portion and • * I ”with a pivotally mounted • m *” * arm arrangement pivotally attached to each extension portion, e.g.

30 of the two pivotally connected arms · ·. The pivot arm constructed as described above allows all of the above operations: such as with a work tool such as a field saw or the like, ···. can be assembled with extremely simple steps • * · * 35 for its standby position and respectively • «a • · ·! . * can be assembled for its operating position. For all of the above operations, the machining device according to the invention requires a very small space around it, particularly in the width direction, which is about twice the width of the support surface, and of course no extra space in the height direction. Because the machine tool 5 according to the invention can be assembled with very little force, its comfort and safety are decisively better than all previous similar machines.

Advantageous embodiments of the machining device according to the invention are disclosed in the dependent claims.

In the following description, the invention will be illustrated in detail with reference to the accompanying drawings, in which Figs. 1a and Ib show a preferred machining device according to the invention in its operating position, seen in side view 20,

The invention relates to a method for a machining device such as M · ·. ***. for use in a field saw or the like, comprising a frame ··· 35 1 with a substantially elongated support surface tp such as a roll plane or the like · *** * ... · workpiece-machined pieces such as logs or the like, machining means 2, such as 118524 6 auxiliary power saw or the like, movement means 3 such as wheels or the like to enable movement on a field saw base, and support members 4 such as height adjustable 5 legs or similar to support the machining device in the operating position I. The machining device is arranged to be assembled for the standby, transport position and / or the like II by forming its body 1 at a central portion la, at which, preferably at opposite ends, are provided extensions Ib which are moved substantially horizontally . The body 1 is assembled from the operating position I of the machining device, in particular by the principle 15 shown in Figures 3a, 3b and 4a, 4b, with a substantially horizontal pivoting arm arrangement 6 which initially moves the extension Ib outwardly s Ib is then moved substantially substantially parallel to the transverse position p in a position adjacent to the center portion la and then further inwardly inwardly parallel to the center portion la.

·· * • · · * · • · * · *; As a preferred embodiment of the method, particularly with reference to the accompanying drawings, it is utilized in connection with a ··· »machining device having, firstly, an auxiliary device. for attaching it to a towing vehicle, such as a drawbar 5 or the like, and first and foremost means for locking means, the first and second extensions of one or more of the swiveling attachments, locking member Ib to each other • · · * ... * in operating position I and the other locking members 9 respectively! ♦ *. means for locking the extension Ib immobilized ··· *. ·· *. in the machine standby, transport position and / or · · 3 5 II. These locking arrangements are not specified in more detail in the accompanying drawings, because '... · a variety of switching arrangements are known per se. Each of the 118524 7 extensions Ib is moved, after releasing the second members of the locking members, by means of an articulated arm assembly 6 consisting of at least two pivotally connected pivot arms 6a which are pivotally angled to one another in the operating position I and and to the extension portion Ib, longitudinally outwardly s1 apart from the central portion la so that said pivot arms 6a are aligned substantially parallel.

The collapsible machining device of the type described above thus comprises a body 1 arranged to be assembled from its operating position I, in particular by the principle shown in Figures 3a, 3b and 4a, 4b, by moving its associated extension Ib firstly outwardly s next, moving the extension Ib in a substantially transverse direction p to a position 20 centering on the center portion and then further moving the extension portion Ib in the longitudinal direction inward along the center portion la. As shown in the accompanying drawings, the jig includes a substantially horizontal plane: * · *: a pivoting wedge arm assembly 6 including a · !. 25 at least two pivotally connected pivot arms 6a which are pivotally attached to each other at the opposite ends, such as pivotally, • · hinged and / or similarly in the frame 1 «· • f * 'In the middle section la and in the extension section Ib.

Preferably, the support members 4 include one or more legs that are pivotally mounted and adjustable in height 5 on one or both sides of a central portion 1a and / or extension Ib (this type of arrangement is not shown in more detail in the accompanying drawings).

On the other hand, it is advantageous in this connection to provide the parts 10, particularly those of the extension portions Ib of the support members, with removably fastening and adjustable length brackets 4a, since the articulation arrangement moves along the lower surface of the extension portion Ib. Ko. the brackets are arranged to be coupled to each extension Ib preferably by means of a quick-locking principle, such as by attaching to the seats 4b at opposite corners of the extension Ib by a lockable shape fitting or the like. In this connection, the brackets 4a are preferably arranged 20 adjustable in length by telescopic principle, with corresponding counterparts 4a ', 4a "having a pin and hole array arrangement or the like for adjusting and locking their overall length.

It is understood that the invention is not limited to the above-mentioned *: ** or described applications, but that it can, of course, be modified in many ways within the spirit of the invention. . First, the extension ·· ♦ parts may consist of two or 30 more extension pieces in the longitudinal direction, however, the practical problem of III in this type of extension joints is that they easily become over time to some degree loose. structure. On the other hand, the solutions used to move the l **: extensions can, of course, be implemented with a variety of • · \ .I joint solutions instead of the ones shown. In this context, it may still be possible to utilize some type of slide and / or telescopic arrangement to accomplish the same purpose 118524 9, whereby the required constructions may, of course, depart quite a lot from the extremely simple articulation arrangement of the type described above. Of course, the 5 types of machine tool specifically designed for field saws may also be provided with occupational safety equipment in a manner different from that described in the drawings, or it may be equipped with, e.g., multiple wheels or 10 roller solutions and / or replaceable foot pads, etc.
