    The invention relates to equipment for guiding and leveling webs of paper or paperboard that are fed into a high speed paper cutter raspberry. It specifically refers to a device that performs the functions of leveling, adjusting tension, and adjusting the lateral position of the web. .
    The purpose of the invention is to increase reliability and ease of operation.
    Figure 1 shows the device, side view; Figure 2 is the same, front view; Fig. 3 is a side view of the pivoting guide frame; 4 is a pivot frame, top view; figure 5 is the same section; figure 6 is a section aa in figure 4; in fig. 7 is section BB in FIG. on Fig - section bb In Fig, 2; Fig. 9 shows a second embodiment of the device.
    An installation (FIG. 1) for transporting six simultaneous webs of paper consists of six identical devices, one of which is indicated by pos. 1. Paper webs 2 are pulled through the device along a zigzag path: through the upper roller 3 under the lower roller 4 and are directed to a high-speed paper-cutting machine 5..
    The device I includes a guide frame 6 having three vertical supporting elements 7-9, two horizontal supporting elements 10 and II, as well as diagonal supporting elements 12 and 13. The guide frame is rotatably mounted on a horizontal pivot pin 14 (shown in FIG. .4 and 6), which extends at one end into the hinge support 15, mounted on the guide frame 6, and the other end into the second hinge support 16, installed) in the bracket 17, which is attached to two fixed side walls 18 and 19. Thus, frame 6 can orachivats mainly in a vertical plane about a horizontal pivot pin 14. Furthermore, the axis of rotation 6 the frame relative to the pivoting pin 4, perpendicular to and intersects the axis of rotation of the upper, roller 3.
    In order for frame 6 to be oriented mainly vertically, the presence of two complexes is provided

    com roller limiters. The upper stops 20 and 21 (Fig. 8) include an installation unit 22 attached directly to the mounting bracket 17 and having a roller wheel 23 attached to it with rotatable capability. The wheel 23 is enclosed in a channel bar or track 24, which, in turn, is attached to the support member 10 of the frame 6. The interaction of the roller wheel 23 with the track 24 allows the frame 6 to rotate relative to the pivot pin 14, but does not allow the frame to rotate along the vertical axis.
    The upper horizontal support member 10 has a reinforcement bracket 25 attached thereto, which joins and strengthens support members 8, 10, 12 and 13. The hinge support I5 is attached to the bracket 25 by means of a mounting plate 26, which is held relative to the bracket 25 by bolts 27 o
    The support bracket 17 (Fig. 8) includes a channel 28, having a high vertical wall 29 and two shorter horizontal walls 30 and 31. The reinforcement and mounting plate 32 is attached to the open side of the channel 28, the mounting block 22, in turn, is attached to the reinforcement plate and the mounting plate 32 and the upper horizontal wall 11. The end plates 33 and 34 are fixed to different ends of the channel 28, and corresponding fastening means, for example bolts 35, fasten the plates 33 and 34 to the fixed walls 18 and 19. The reinforcing and mounting plate 32 does not pass along the entire length of the channel 28, thanks to which there is
    5 access to install and remove fastening bolts 35.
    The bottom pair of roller stops 36 and 37 are shown in FIGS. 2, 4, 5, 7..
    The lower horizontal support element 11 carries a bracket 38 to which a channel bar or track 39 is attached (Fig. 7). The track 39 may be removably attached to the bracket 38 using fasteners such as bolts, so that this track can be replaced with a new one when it is worn out. The track 39 has a protruding part in the form of a tongue 40 forming inside

    The surface of the track 41, with which the roller 42 interacts. The roller 42 is rotatably mounted on the mounting block 43, which in turn is attached to the mounting bracket 44. The mounting bracket itself is attached to the relatively rigid support bar 45. The lower roller 4 for paper mounted on the pivoting frame 6 by means of the mounting bracket 46, the paper web 2 moving along the roller 4 under tension between the roller 4 and the frame 6, forcing the surface of the track 41 to interact and press against the roller 42.
    Thus, the pivot frame 6 can pivot relative to the pivot pin 14, but at the same time its deviation from the vertical orientation is limited. Roller stops provide movement of the low friction pivoting frame, maintaining its vertical stability.
    As can be seen from FIGS. 1, 2 and 3, after the web 2 leaves the lower roller 4, it passes through an edge position sensor 47, which is mounted on a transverse rod 48 attached to fixed walls 1 8 and 19. The transverse rod 48 has flat surface 49 in order to sensor. The 47 edge positions could be selectively moved and adjusted, depending on the desired edge position of the particular paper web being passed through the device. The fixture 50 is designed to hold the edge position sensor 47 in the desired and selected transverse position. A specific type of edge position sensor that can be used for the proposed device is an infrared sensor on light-emitting diodes that sends an error signal on the electrical channel 51 to the device 52 controlling the operation of the drive 53 ..
    The actuator 53 has a first retractable lever 54, which is installed with the possibility of rotation around the axis 55 relative to the lever 56 attached to the mounting beam 57, which is part of the frame 6. The mounting beam 57 passes between the lower horizontal support element 11 and the diagonal support element 13.
    The second extendable lever 58 is rotatably fixed at point 59 to the rigid and stationary installation block 60, which in turn is attached to the fixed wall 19. When the movable lever of the drive 53 is in the extended position, the frame 6 rotates with respect to
    0 of the pivot pin 14 in a clockwise direction, as seen in FIG. When the retractable lever of the actuator 53 is retracted from the extended position, the pivoting frame 6 rotates 5s with respect to the pivot pin 14 in a counterclockwise direction. The drive is equipped with rubber shock absorbers 61 to absorb the impacts of the support of the drive 53 when it makes
    0 reciprocating movement with increasing and decreasing the length of the drive lever.
    Thus, the edge position sensor 47 senses the movement
    5 edges of the web 2 relative to this sensor; the error signal through the proportional control is sent to the actuator, allowing the frame 6 to rotate to move
    0 web edge 2 back to the desired position relative to the sensor.
    The lower roller mounted on the axis 62, the first end 63 of which is installed
    5 can be rotated relative to the pivot pin 64, and its second end 65 is mounted in an adjustable sub-tool, 66
    0 by a knob 67, which can be rotated to cause the second end 65 of axis 62 to move up or down relative to the first end 63. With this adjustment, the function
    5 to compensate for the weak edge of the blinker fabric by extending the strip path from the weak or sagging side. Since the movement of the roller is limited to the vertical plane, and also because the edge position sensor 47 is located behind and next to the adjustable roller 4, the edge position is held more accurately in the proposed device than in the existing devices, where a separate fixture was used to adjust the weak edge.

    The leveling of the paper web 2 can be carried out by means 68 for smoothing the poty shown in FIGS. 3 and 4. This includes a pair of slightly rounded rods 69 and 70, each end of which is attached to the axis 71 of the upper roller 3. Each the rods can be rolled onto the web 2 by means of an electric motor 71 and a gearbox 72, driving a gear 73, to which the rods are attached, in order to remove the folds extending in any direction.
    In Fig. 9, the alternate-) 5 two horizontal rollers are shown for the after-run version of the unfolding means 74, which includes two rods 75 and 76 that can be selectively rolled onto the web 2 to automatically level the folds at a predetermined position and connected to the lot . The device is also provided with a means for controlling the tension of the web. The support rod 45, to which the lower set of roller stops 36, 37 is attached, is mounted on the suspension 77. Suspension 77 is installed in the hinges 78 on one side, and on the second side has a torsion mount with adjusting
    control means the rotational drive of the guide frame for adjusting the position of the lower roller, including a sliding lever connected to the frame, 25 is different in that, in order to increase reliability of operation and ease of operation, it has installed on the guide frame between the upper and lower rollers mediums

Tension sensor 80 tensioning the blade for flattening the web when not mounted on the side wall 18 to sense the movement of the bracket relative to the hinge 78 and thus perceive. canvases. The tension of the web by creating lateral displacement directs the instantaneous force on the hinges of the frame, the tension sensor of the web and ball 78, which counteracts also the suspension for the support rod, rotate in proportion to the force attached to the side wall with tension from the side of the adjustment which can be rotated by the force of the mutually screw 79. The perceived tension between the roller and e0 depends on the position of the paper fields and the guide frame, while the lot is on the surface of the roller 4, which means about: control the side edges
    the canvas is mounted on the frame between the side walls after the bottom roller
