    An apparatus for securing a tensioned plastic band which has a rotatable tensioning wheel and a friction shoe which is located adjacent a band path for two mutually overlapping end portions of a band located around an article is disclosed. The shoe is reciprocatable transversely to the band path, and displaceable into and out of contact with the upper band end portion. A single drive means is permanently coupled to the shoe for reciprocation, and drives the tensioning wheel via a torque-sensitive coupling. In operation, the shoe is initially out of contact with the band, and the wheel is driven so as to tension the band until a predetermined tension is reached. Thereupon the coupling uncouples, and actuates means which urge the shoe against the band. This causes relative motion of the band ends, resulting in their being frictionally welded together. The uncoupling also actuates a cutting member for the band. Thus the sequence of tensioning, welding and cutting is performed automatically.

A device for tensioning, joining and lengths of strap of synthetic material contains units located in the front part i for tensioning, joining and lengths of bandage tape laid around the package. In its rear part, the drive motor 3 and the electrical switching and control elements & All parts are enclosed by housing 4, which 3, over the longitudinal direction of the device, is covered by a belt 5, with which the control plate 6 can be lifted and retracted from the tension wheel 7 so that oo of the end 8 to 9 can be loaded into the channel 10 dl. the direction of the belt between the tension wheel 7 and the support plates 6 on the side, i.e., in front (Fig. 1). In this case, lift up the laterally positioned belt control lever 11, which can move transversely to the longitudinal direction of the device and allows the processing of the bandage tapes of various widths. Inside the handle 5, a folding pressure rod 12 is installed, which acts on the upper end 13 of each organ 14, having the shape of a rocker arm and by means of which the movable fretklon shoe can return to its original position. On the upper side of the housing 4 there is a switch 15, with which the automatic control for the drive motor 3 can be turned on. The tension wheel 7 is tightly pressed to the upper end 8 of the lectures, which is pressed by the counterplate by the plate 6 to the lower wheel and is ti km back to the direction of the arrow 16, and the tension wheel rotates in the direction of the arrow 17. The tension wheel 7 is rotatably mounted in the front part 1 of the device in the housing 4 (Fig. 7) and is suitable for moving the worm gear 18, the worm gear 19 of which sits to the hall of the tensioning wheel 20, it is driven by a screw 21, which extends to the E-1a. Direction of the hull (Fig. 6) - and the shaft 22 of which at its rear end 23 is rigidly connected to the carrier 24 plz.-hetar 25th gear set. The planetary gear wheels 26 installed in bearings of the planetary gearbox 26 are entered in zatsechenn on one side with the centrifugal gear wheel 27 and on the other side with samshevy gear wheel 28, 74 which sits on the drive shaft 2) drive transfer 30. drive shaft 31 which is connected by p edelnoy coupling 32 to a drive motor 3 (FIG. 3). On the drive shaft 31, which is mounted in supports in the housing 4 parallel to the drive shaft 29 and has a small gear 33 engaging with a gear 34 mounted on the drive shaft 29. Also with the possibility of rotation, an eccentric 35, which through a lead 36 leads The movable friction block 37, which is located above the tape direction channel 10 on the front side of the device and can rotate reciprocatingly around the vertical axis 38 in the direction of the arrow 39 (Fig. 7), is activated. The movable frikpiocpa block 37 (Fig. 2) has a longitudinal section, close to two-Tauri. corrugated and covers with its both ends 40 and 41 a supporting element 42 in 4j which also has a vertical axis 38 so that the movable frykshonny pad 37 can not only rotate, but also move back and forth in its longitudinal direction within certain limits. In order to make this possible, between the support element 42 and the front ends 40 and 4 by moving the friction pad 37 there is a sufficient gap 43. At the rear end 44 of the jumper 45 of the friction pad 37, between the two rear ends. 46 and 47 are mounted, with the possibility of rotation, a roller 48, which consists of a zholts mounted on ball bearings (Fig. 4). This pressure roller 48 is influenced by a pressure body 14 consisting of a pressure lever, which at its lower end 49 is rotatably mounted around the journal 50 in the housing 4. The body 14 also has, at its lower end, a protrusion 51, by which it comes under the upper rear end 46, which is behind the toggle rec 44, keeps the mobile friction block 37 in its upper inactive position, in which it leaves the belt direction channel 10 free and does not affect the ends 8 and 9 cents. At its upper end, the 3 pressure member is pivotally connected by means of a hinge pin 52 to the back of the hinge lever 53, the front part of which is pivotally mounted on the horizontal axis 54 in KOptiyce for 4 hours extends beyond this axis 54. For the front: .i end 55 of the hinge lever 53 hook : 1 - ::. With tension spring 56, which. (Fixed in the housing 4 and tends to pull
    i1
    the front end 55 of the hinge lever 53 down, and thus, rotate the hinge lever 53 around the axis 54 counterclockwise. Thus, the hinge lever 53 deflects up slightly at its hinge 57, but there it will not fit the stop 58 and this at its top. the side is not rigidly fixed on the hinge 57.
    A strong extension spring 59, which is located almost horizontally in the recess 60 of the housing and its rear end 61 is fixed in the housing 4 (Fig. 5), is hooked onto the hinge pin 52. The tension spring 59 tends to turn the pressure member 14 counterclockwise, which, however, is prevented by the hinge lever 53 if it is in the position (Fig. 2) when its hinge 57 lies against the stop 58.
    With the front end 55 (FIG. 2) of the hinge lever 53, the lever 61 is also pivotally connected, which is pivotally connected to the swing lever 62, which can swing around the axis 63 installed in the housing and with its rear bent end 64 presses the loop end 65 a spring that extends through an elongated hole 66 in the intermediate wall 67 of the housing into the zone of the system of levers.
    At the rear end of the front part 1 (Fig. 2) of the device is above the tape direction channel 10 a block 68 for guiding the knife, in which a sleeve 69 for guiding the knife is mounted with the possibility of vertical movement, a knife holder 70 at its lower end fixed on by means of screws 71 with a head 72, a cutting element 73, for example a knife plate. The blade plate of the cutting body 73 is partially cylindrical and curved according to the arc of a circle; the center of the heel is located on the axis 38 of the movable friction pad.
    The knife guide 69 has a blind hole 74 open upward in which a pressure spring 75 is placed, on one side resting on the bottom of the blind hole 74, and on the other hand on the upper base 76 of the knife guide 68 and strives to push the sleeve 69 with the knife holder and the cutting body 73 fixed on it down. The pressure spring 75 surrounds the rod 77, which is fixed in the lower part of the sleeve 69, penetrates the upper base 76 of the block 68 and with its free end is pivotally connected to the crank lever 78, which bends the beveled end 79 of its other free knee VO to the rear edge of the pressure member 14 .
    176
    The crank lever 78 (FIG. 2) does not have an upward sleeve 69 and with it a knife holder and a cutting member 73, contrary to the effect of the pressure spring 75, and keeps the cutting member in its inoperative position.
    The cylindrical gear wheel 27 (Figs. 3 and 6) is rotatably mounted on the screw shaft 22 by means of an annular flange 81, which is surrounded with a flange gap. The main part 82 of the switching sleeve 83, which is mounted on the screw shaft 22, is also rotatable. On the annular flange 81 of the cylindrical gear wheel 27, a loop spring 84 is wound under tension, which serves as a limit clutch, one rear end 65 of which protrudes through the oblong hole 66 of the intermediate wall 67 and abuts the curved end 64 of the swing arm 62. The other rear end 85 is looped spring 84 is rigidly connected to the switching sleeve 83 (Fig. 6) ..
    The switching sleeve 83 (Fig. 3) has a first lug 86 that extends radially outwards and a second diametrically opposed protrusion 87, which also extends radially outwards. The first protrusion 86 of the switching sleeve 83 enters the recess 88 of the housing 4 and rests on one end 89 of the spring element 90, which is. the compression spring, with its other end 91, rests on the counter support 92, which it sets an adjusting screw 93, protruding from the housing 4 with its upper threaded end 94, onto which an adjusting nut 95 is screwed to the dp for adjusting the tightening of the spring element 90.
    The second protrusion 87 of the switching sleeve 83 is inserted through the opening 96 in the intermediate wall 67 of the housing inside the recess 60 and extends under the hinge lever 53 in its part located in front of the swing axis 54.
    In order to easily insert the koitsi 8 and 9 of the tape into the channel of the direction of the tape and securely hold them there, without obstructing the lateral rotational movement of the upper end 8 of the tape relative to the lower end 9 of the tape, in the device base plate 97, and in the horizontal partition 98, covering the upper side of the channel 10 of the direction of the tape, blind holes 99 and 100 are made on both longitudinal sides of the channel, in which the run-in elements 102, n |) are loaded with balls loaded by pressure springs 101. In this case, the slope elements 102, which are free from their blind holes 99 and 100, abut respectively on opposite surfaces, which 71 limit the belt direction channel 10 on the upper side and on the lower side, i.e., the obratnye elements located in the base plate 97 102 are pressed with their springs 101 to the lower surface of the horizontal partition 98, while the rolling elements 102 placed in the blind holes 100 of the horizontal partition 98 are pressed against their springs 101 against the upper surface of the base plate 97. The copiers 102 (Figs. 2, 8 and 9) are placed respectively in pairs near the ends 8 and 9 of the tape and placed in the base plate 97, the run-in elements 102 are installed in the longitudinal direction of the tape from the horizontal partition 98 of the rolling-in elements 102. A device for tensioning, joining and lengths of banding tapes of synthetic material works as follows. After the bandage tape is laid around the package and the ends .8 and 9 of the tape are filled in front of the tape direction channel 10, the counter plate 6 is retracted by the handle 5 from the tension wheel 7, the handle 5 is released so that the counter plate 6 presses the ends 8 and 9 of the belt to the tension wheel 7. Then, by means of the switch 15, the drive motor 3 is switched on according to the appropriate control circuit. The rotating drive shaft 31 then rotates reciprocatingly through the driver 36 the movable friction block 37 into the elevated position (FIG. 2), with the upper rear end 46 resting on the protrusion 51 of the pressure member 14. The moving friction block 37 therefore does not carry the upper from the 8 and 9 ribbons located under it, and the ends of the belt are moving freely. At the same time, the sun gear 28, which drives the planetary gears 26, is set in motion with the help of the drive front 30. This is because of the planar gear 27 of the planetary gear. fixed by a loop spring 84 fixed at first to the switching sleeve 83, the planetary gears 26 roll along the internal teeth of the cylindrical gear wheel 27 and thus rotate the worm shaft 22 rigidly connected to the planet carrier, which through the worm gear 19 leads moving the tension wheel shaft 20 so that the tension wheel connected firmly to twisting with this shaft, p rotates and the upper end 8 of the bandage tape through 7 does not move the device in the direction of arrow 16 and thereby exposes tension, as the lower end 9 of the belt is clamped in the device. As soon as the desired tension of the belt exceeds the value established by the spring element 90, it is transmitted from the spur gear 27 through. The coupling on the switching sleeve 83 of the rotations, which exudes from the loop spring 84, overcomes the force of the spring element 90 on which the first protrusion 86 of the switching sleeve rests. Thus, the switching sleeve 83 (Fig. 3) clockwise (arrow 103) begins to rotate. This rotation has the consequence that the second protrusion 87 of the switching sleeve 83 raises (Fig. 2) the front end of the hinged lever 53, despite the effect of the tension spring. At the same time, the hinge 57 of the hinged lever 53 bends downwardly so that the pressure member 14 loses its support at the upper end and the stretching spring 59 can act (FIG. 5), which turns the pressure member 14 forward counterclockwise. Thus, the protrusion 51 releases the movable friction block 37 and the lower end 49 of the pressure member 14, presses the pressure roller 48 mounted in the supports on the rear end 44 of the movable friction pad 37. Due to this the mobile friction block 37, which is still moves back and forth with continued operation of the drive, pushes down and draws the upper end 8 of the belt into motion, rotating it back and forth around the vertical axis 38 under the lever pressure exerted by the pressure member 14. Thereby yrabat | The heat of friction is known in a known manner, due to which the surfaces of the ends of the wearer are softened so that a connection can be achieved by melting if the friction block 7 is later stopped under pressure. If the pressure member 14 is rotated forward by the action of the spring 59, the crank lever 78 rotates with it, which abuts against its trailing edge. The blade 69 of the knife direction and the connected - with it the knife holder is released and pressed down by the pressure spring 75 until the head 72 of the screw 71 does not lie on the upper side of the recess at the rear lower end of the movable friction pad 37. T; . As the upper end 8 of the tape moves an e-transversely transverse to the longitudinal direction of the tape. Under the now pressed cutting member 73, it is then cut off by the cutting member 73, which, however, does not touch the lower end 9 of the tape at all.
    If the pressure member, the body 14 is rotated forward counterclockwise, the switch 104 is actuated, which until cic is pressed and held by the upper end 13 of the pressure member 14. in its non-working position. This switch 104 allows a time relay, which allows further rotation. drive motor 3 some-. The second time, which is designed so that the sliding friction block 37, which is reciprocated by a reciprocating motor driven under pressure of the pressure member 14, can produce the tags required for the friction welding process n superficially. The ribs were strung together in the desired way.
    Simultaneously with the rotation of the hinge lever 53, the lever 61 rotates the swing lever 62 clockwise, and its curved 64 pin presses 65 on one end, consisting of a loop loop 84 of the sleeve 84. The sleeve 84 is thus freed so that the spur gear 26 can rotate on the worm shaft 22. The sun gear 28 of the planetary gear 25 is installed then through the planetary gear wheels 26 in the rotating gear 27, and the planet carrier and the worm gear connected to it thaws.
    If the time relay then worked, it starts the drive motor 3 according to the corresponding control circuit. This stops the movable friction block 37 while the pressure left by the pressure member 14 on the friction block is maintained. Thanks to this, the ends, tightly pressed to each other, can be welded to each other in a heated
    zone and thereby bond firmly to the gap.
    By pressing the handle 5 downwards, the backing plate 6 can be removed from the tension wheel 7 and the device can be removed from the side of the tie. Here, the rolling elements 102 are pressed into their own. blind holes 99 and 100 so that the bandage tape can slide the ribbon forward out of the channel 10 of the direction.
    When the knob 5 is knocked into place, a flap located in it. The clamp rod 12 seizes the upper end 13 of the pressure member 14 and depresses it, despite the impact, of the expansion springs 59, to its original position (Fig. 2), while the crank lever 78 and thereby removing the cutting tool 68-73. In addition, the upper end 13 presses again. switch 04 and brings it to its original position.
    The invention is not limited to this exemplary embodiment, but various changes and additions are possible, without departing from the scope of the invention. Instead of the shown clutch, consisting of a loop spring, an electromagnetic clutch, a sliding ratchet clutch, a pneumatic or hydraulic clutch can be used to disconnect the tension wheel from the drive and to simultaneously actuate the pressure member. In addition, you can use other tension devices such as devices for tensioning belts, or use, instead of a pressure lever, a hydraulic pressure member to press
    movable friction pads down.
    The use of the invention makes it possible to simplify the design of the device for tensioning, joining and cutting the straps of synthetic material and to increase its reliability. ats and - / Al SR: §§ftg ffff 9677678281 Fig.Z ± 2 8J
