    A longitudinal lumber conveyor is provided with an adjustable end stop for cutting a piece of lumber into several pieces. The adjustable end stop is mounted on a slide which is adjustable hydraulically beneath the plane of the conveyor. The slide is operable between adjustable end switches which are activated to indicate the desired position of the slide. The slide may be moved between the various end positions when a photocell device mounted on the slide senses that a piece of lumber is not present at the photocell device. The slide has rotatable stop arms mounted on a shaft of the slide which are hydraulically rotatable from a first stop position above the plane of the conveyor to a second position below the plane.

    (54) DEVICE FOR CLOTHING STRAP
    I
    The invention relates to cutting devices with movable stops for measuring the lengths of sawn timber and can be used in forestry and forestry enterprises. revamping industry as part of a high-speed and productive line for processing various types of timber.
    A device for drawing of logs, including a bed, is known; a longitudinal feed mechanism, completed in the form of a conveyor; a stop mounted on a slider for measuring the length of assortments; a longitudinal direction of the slider; a hydraulic cylinder for moving the slider and a guide; a slider stop device made in a series of successively mounted on the Bed and connected to the control panel elements and a circular saw with a drive of its raising and lowering Ij.
    However, the known device has a low productivity / since each sawn assortment must be dropped to one or the other 5 side by a resetting device, and this prevents it from being installed in a high-performance line. .
    The purpose of the invention is to increase the production
    Q water content
    The goal is achieved by the fact that the slider is located under the working branch of the conveyor and is equipped with a plate for interaction with locking elements and at least one additional stop, with the stops mounted on the slider and have a hydraulic cylinder for raising and lowering them, and the locking elements are made 2 (3 position sensors.

    2. Adjacent to the conveyor. The inclined plane 3 is located adjacent to the roller conveyor 4, behind which there is a longitudinal feed mechanism designed as a chain conveyor 5. Between transporters 4 and 5 there is a zone 6 with a circular saw 7, which has a lifting and starting wire in: a plane perpendicular to the direction of movement of the conveyors. "Conveyor 5 consists of a frame 8, on which are mounted sprockets 10-12 chain drums with 13 endless chains 14 passing through the I-shaped guides 14. On the frame 8 there is mounted an electric motor 15 connected with sprockets 9, and on the chain drum 12 there are fixed gears 16, between which the chains 14 pass. formed by the upper branches of the mi chains, side walls 1.7 and 18 are located, welded to the cutter 8. On frame 8, there are mounted longitudinal guides 19 and 20, which are parallel to guides 13 and located along the longitudinal axis of the conveyor 5. On guides 19 and 20 there is a slider 21 with a shaft 22, perpendicular to the longitudinal axis of the conveyor 5. On the shaft 22, three stops 23 and two control levers 24 are mounted. The control levers 24 are connected to the rod of the hydraulic cylinder 25, which rotates the levers and the shaft 22 rigidly connected to them. In the lower part of the slide 21 is located wives bracket 26 to which the pr the end of the rod 27 of the hydraulic cylinder 2 is connected. The hydraulic cylinder 28 is pivotally connected to the support 29, which in turn is connected via a shock absorber 30 to the frame 8. With this design, apparently, the movement of the rod 27 of the hydraulic cylinder 28 will be accompanied by movement of the slide 21 along the guides 19 and 20. In the lower part of the bracket 26, the bar 31 is fixed, and on the frame 8, under the bracket 26, guides 32 and 33 are mounted, which are parallel to the guides 19 and 20 and in section have the form shown in FIG. 5. On the guides 32 and 33, position sensors 34 (end microswitches) are installed, which can be moved along the guides 32 and 33. The sensors are closed by a bar 31, which abuts the moving rod 35 of the corresponding position sensor. As shown in FIG. 3, three sensors 34 are mounted on the rail 32, and two on the rail 33, which can be mounted in any position relative to the sensors mounted on the other rail. The distance between the sensors installed at opposite ends of the guides and, consequently, the length of the guides slightly exceeds 1m. The photo cells 36 and 37 mounted on the slider 21 are located against the windows 38 and 39, which are trimmed in the side walls 17 and 18 above the upper branches of the chains 14 that are expanded in the guides 13. There is another photo cell 40 in the installation, schematically shown in FIG. 1 whose light beam passes through a free zone 6 located between conveyors 4 and 5. These photocells are connected to an electronic control circuit (not shown, in which there are various relays and a computing device with a push-button console. In the area of the circular saw 7 there is a clamping the device that holds; the sawn log lives. The device works as follows. The log to be cut into shorter parts is moved by the conveyor 1 up to the stop 2 and then gets onto the roller conveyor 4 and from it One of the ends is sawed off in Section 7. At this time, a computer with a program that provides the minimum amount of waste, depending on the actual length of the log, provides data on the length of the individual parts into which the dando log should be cut. to the corresponding final microswitch, when the strips 31 approaching which the slider 21 stops, and after the slider stops (in a certain position), the stops 23 are turned into the operating position. 4 on the chain conveyor 5 the log is moved by the conveyor 5 all the way to the stops 23 (the teeth of the gear wheels 1b supporting the log moving) "When the log approaches the stops 23 the moving log kinetic energy is partially absorbed by the deformation of the bending in the vertical plane (. . 2) stops, and a shock absorber 30 partially decreasing upon impact, which practically completely eliminates the rebound of the log from the stops. At this moment, the saoaiM device of the circular saw 7 and the saw, moving perpendicularly to the transporter, triggers to cut off a piece of the appropriate length from the log. After that, the saw goes back and the device releases the log. The lever stops fall down and the piece sawn off from the log is moved by the chain conveyor 5 to the next section of the process line. Data about this goes to the computer, and after the photocell 40 shows that there is no log in zone 6, the next log is fed to the roller conveyor 4 (if the photocell 40 registers the presence of the remaining piece of log in zone 6, then a new log will not arrive). Once the new logs arriving on the trans- port 4 are cut in the same way. The presence of several limit switches 34, which can be installed in any place along the guides 32 and 33, allows the length of the pieces to be cut from the log to vary, the parallel length of which is determined by the length of the guides 32 and 33, equal to It is said above, approximately 1 m. The electronic control circuit can be made in such a way that the stroke of the slider 21 with the stops 23 and the strap 31 when the length of the cut pieces is minimized is minimal (you can also move the slider 21 always from the same initial position). In principle, it is not at all necessary to control the operation of the entire installation from the computer. To control the installation, you can use the push-button control panel. In this case, along the conveyor you can install a measuring line, with which the operator can control the length of the cut-from logs of pieces. The device proposed in the invention thus makes it possible to cut various timber (logs) into separate pieces of equal or unequal length with an absolutely minimum number of 7 turns. . Claims Device for splitting whips, including a stand, conveyor-made longitudinal feed mechanism mounted on a slider support for measuring the length of assortments, longitudinal slider guides, slide hydraulic cylinder along the guides, slider stop device made in a row successively mounted on the frame and associated with the control panel of the fixing elements and a circular saw with a drive for raising and lowering it, characterized in that,. In order to increase productivity, the slider is located under the working branch of the conveyor c and is provided with a strap for engaging with locking elements and at least one additional stop, the stops being pivotally mounted on the slider and having their lift and lowering hydraulic cylinder, and the locking elements are positioned as position sensors.
