SU501876A1 - The device for debarking and tattoos of logs - Google Patents

Description

It is realized due to the planetary mechanism 13 and the faceplate of the rotor 14.

The adjustment and adjustment of the pitting depth can be done during operation (on the fly) with the help of an additional hydraulic cylinder (servomotor) 15 displacing the stator gear relative to the stator copier in the required direction. In this case, the tool moves to the center of the head if you need to increase the depth of the tattoo or the tool moves from the center of the head - if you need to reduce the depth of the tattoo.

The leg portion of the tool 10 is a knife head with a flat knife 16 mounted parallel to or forming an angle to the log, with a feed limiter 17 in the form of a steel ruler fixed with some excess parallel to the blade of the knife. The knife head has a spring floating suspension, allowing it to self-adjust in accordance with the shape of the side surface of the bark log, and regardless of the position of the second, pinning part, combined tool. This part of the tool is located along the feed of the log behind the debarking part and is a punctured roller (drum) with an individual suspension, which rolls along the lateral surface of the log as the rotor rotates. The hinge roller suspension is equipped with a double spring 18, which provides a sufficient depth of pitting of the log surface.

The spinning rollers do not have a self-drive, but rotate when they roll the surface of the log during the rotation of the rotor. On a rim of a puncturing roller in a certain order and frequency are located thorns-needles having individual fastening. The pickup roller rotates freely on the axis 19, which is installed in the cheeks of the suspensions 20. The suspension cheeks are fixed on the axis 21. Such a suspension allows the pickup roller to self-align in the direction of the total vector defined by the two components of the log. During the operation of the device, the magnitudes of these speeds vary considerably, and therefore the angle of installation of the incanking roller to the longitudinal axis of the log automatically changes.

Instead of a rotor with a radial arrangement of tool holders in the installation can be installed rotor with hinged fastener tool holders.

The tool holder 22 is hinged to the rotor 2 of the head using the axis 23.

The tool holder consists of three parts: the middle part of the tool holder, the cantilever part 24 with the roller 25 and its end part 26, which is U-shaped and serves to fix the axis 27 of the puncturing roller 28. Self-aligning of the puncturing roller to the required angle to the axis of the log is automatically performed account hinge end of the tool holder. The axis of this hinge 29 is fixed on the middle part of the tool holder, which has a tide, on which is mounted a separate suspension of the debarking tool. The deking tool 10 has an individual articulated spring suspension, similar to that described earlier. The tool holders of this type are controlled by cams 30 fixed to the ring rotor 31 of the head rotor.

The device works as follows. Before feeding the next log into the head, the centering feet and, together with them, tool holders with tools are moved apart,

ensuring that the log enters the rotor of the head freely, without hitting the rotating tools and without large loads on the feeding device. Without stopping the movement of the log, the clamping paws center it in the head and clamp it with a force sufficient to eliminate the possibility of turning it during processing. Simultaneously and synchronously with the paws, the tool holders are moved, the combined tool is lowered onto the surface.

logs - at this moment, the process of debarking logs and tattooing of the debarking begins. Significant pressure force of the pinning rollers is created already after the rollers enter the surface of the log,

which allows continuous operation of the device without stopping the TIPER rotor for refueling the next log.

The tools are controlled automatically in accordance with the position of the centering paws or rows, which determine the diameter of the log at the machining site.

If necessary, the device can only do debarking or tattooed only, with the corresponding parts of the instrument being removed.
