Description

[Detailed explanation of the invention] Traditionally, vertical splicing tree cutting machines have been used with large mechanisms that can mass-produce even small square timbers, but this type of machine is unsuitable for processing construction materials. This is especially true when there is a shortage of wood, as we are now.

In view of the current situation, the purpose of this invention is to vertically splice and reuse the rust and leftover wood produced during construction and other processing of wood, and to make it lightweight, easy to transport, and compact. This invention relates to a paulownia cutting machine for vertical splicing of wood, which enables the vertical splicing of large and small pieces of wood with a small horsepower, and also enables easy processing at the work site.

Now, if you ask questions about one embodiment of the present invention with reference to the drawings, the questions are as follows.

In the figure, reference numeral 1 denotes a pedestal for the material that is advanced and retracted by a feed screw mechanism 2, and this feed screw mechanism 2 is provided with a screw thread a that is the same as or proportional to the mounting pitch of a cutter, which will be described later.

Reference numerals 3 and 3 denote a pair of columns provided on the left and right sides of the pedestal 1, and a support plate 5 for the lifting bundle 4 is provided at the upper end of the support plate 3.
A holding plate 6 made of material is provided at the lower end of the handle 4, and a ruler plate is provided at one end of the holding plate 6 at a position perpendicular to the holding plate 6.

Reference numerals 7 and 7 denote a pair of front and rear guide rods adjacent to the material holder 1, into which a tool rest 8 is fitted and supported.

Reference numeral 9 indicates a plurality of cutters arranged at the same pitch at one end of the tool rest 8, 10 an electric motor provided at the other end of the tool rest 8, and 11 a pulley 12 provided on the cutter 9 and a pulley 13 provided on the electric motor 10. A tensioned belt 14 is a stopper installed on the underside of the tool rest 8 and limits the feeding of the material, 15° 15 is a pair of supports established on the left and right sides of the tool rest 8, each with a return spring 16 mounted on the exterior. It is.

Reference numeral 17 denotes a pressing plate fitted to the upper end of the support column 15.15 and connected to the tool rest 8 by a support rod 18.

Reference numeral 19 denotes a receiving member provided at the center of the pressing plate 17, to which the pressing rods 20 are pivotally connected, and the tips of the pressing rods 20 are linked to the machine base A via the connecting rods 21.

In addition, B is one material support roller, 22 is its fixed plate, 2
Reference numeral 3 denotes an elevating plate which is installed above and parallel to the fixed platen 22 and has a large number of rollers 24 arranged on its upper surface, and 25.25 connects the center of the back surface of the elevating plate 23 and the center part of the upper surface of the fixed platen 22. The bendable connecting rod 26 is a feed screw passed through the center of the connecting portion of one connecting rod 25, and its tip is screwed into a bearing 27 provided at the connecting portion of the other connecting rod 25, and the rear end is screwed into the bearing 27 provided in the connecting portion of the other connecting rod 25. A pusher metal 28 is provided, and a bundle 29 is attached to the outside thereof.

Since the present invention is constructed as described above, when performing Kiritori processing for vertical jointing on a material, the material must be moved along the ruler board provided on the pedestal 1 until the tip touches the stopper. After feeding, the bundle 4 is operated to hold down and stabilize the material on the pedestal 1 with the restraining plate 6 provided at its lower end, and then the pedestal 1 is moved by the feed screw mechanism 2 and the material is delivered to the cutter 9. If the press rod 20 is pressed after facing each other, the press plate 17 related to the press rod 20 presses the spring 16 mounted on the column 15 and presses down the tool rest 8, so that the tip of the tool rest 8 is pressed. The installed cutter 9 contacts the material and cuts paulownia wood for vertical joints, and when the pressing force is released, the pressing plate 1
7 is restored by the restoring force of the spring 16 mounted on the column 15, so by repeating this operation and operating the feed screw mechanism 2 to bring the material directly toward the cutter, the holes 1 of the same pitch can be placed on the desired part of the material. A groove is formed.

However, in this case, since the pitch of the thread a in the feed screw mechanism 2 is the same as or proportional to the arrangement pitch of the cutter, the cutter can move the material forward and backward appropriately and accurately. It is something.

If the material to be fed is long during the processing process, the rear part of the material will protrude rearward from the pedestal. The bendable and extensible connecting rods 25.25 are extended to raise the lifting plate 23 and support the rear part of the material so that it can be easily leveled, thereby facilitating the paulownia cutting work.

In this invention, as described above, the feed screw mechanism advances and retreats the material holder to accurately face the cutter attached to the tool rest to perform paulownia cutting, but the pitch of the cutter and the feed screw mechanism Since the pitch of the thread is set to be the same as or proportional to the pitch of the thread, feeding of the material to the cutter is easy and accurate.

In addition, the device itself is small and has low horsepower, making it easy to move and transport, so it can be used easily at work sites, contributing to the industry as a paulownia cutter for vertical splicing of wood. There are things that can be done.
