On one The end of the slider 15 in the vertical direction is fixed restrictive plate 17, provided with a window 18, for controlling the stacking of the workpiece 19. On the front side of the slider 15 along it is mounted an applicator 20, which can be made in the form of tex lit, in contact with the roller 6 and passing through the groove 21, useful on the rear wall of the bath along the guide bar 14. The cover 4 has a groove 22 through which the upper end of the roller 6 passes, and the cover itself is the table for laying and feeding the blanks 19; On the side of the restriction plate 17 in the groove 22, there is a mechanism for controlling the supply of glue to the roller 6, which is a regulator for the thickness of the spreading by the roller 6 glue. plates (comb) 24, which They are hinged by means of shafts, 25 and 26, respectively, mounted in holes 27 and 28, made on the feed side of the workpiece 19, i.e. in the joint of the installation of the control mechanism of the roller 6. The plates 23 and 24 are kinematically connected with each other by means of the gears 29 and 30, which are in constant engagement with each other. The gear 29 is fixed on the shaft 26 of the plate 23, and the gear 30 is fixed on the shaft 25 of the plate 23. The bottom plate 23 is mounted along the roller 6 and is designed to remove glue from the latter when the roller is idled, i.e. at the moment when the workpiece 19 is not supplied. In this case, the plate 23 is provided with a screw 31 fixing the latter on the shaft 26 in a predetermined position according to a predetermined feed thickness of the adhesive on the roller 6. The upper plate (comb) 24 is provided with notches 32 and a protrusion 33, by means of which the last spring to the bracket 34, mounted on the base, by a spring 35. In this case, the bracket 34 is provided with a screw 36 in contact with the protrusion 33. On the cover 4 on the top of the plate 24, a third plate (comb) 38 is pivotally mounted on the cover 4, ending with the projections 39, the Mits in the notches 32 on the top plate (comb) 24., Pass 24 also serves as a control feed of the workpiece to the spreading area. To spontaneously adjust the position, the plate (comb) 38 is spring-biased downwards by a spring 40 mounted on a sleeve 41 also mounted on the lid 4. In order to transport the workpieces from above, the second upper conveyor roller 42 is mounted on the same axis vertically, which is rotatably mounted on bracket 43 in sleeves 44 and 45 on the shaft 46. In turn, the bracket 43 is installed in the direction of the 1x bracket 47 with a car. the possibility of vertical movement from the screw 48 entering the threaded hole on the bracket 43 and provided with a handwheel 49. A gear 50 fixed to the free end of the shaft 46 of the roller 46 is fitted with a high tooth and meshes with the gear 10, to effect the rotation of the rollers 6 and 42, the device is equipped with a drive mechanism, which is manufactured in the form of an electric motor 51 mounted on a plate 52 mounted on the base of the table 1. The electric motor 51 through a worm gear 53, shaft 54 with a pulley 53 fixed on it through a belt This drive 56 and the pulley 11 on the shaft 7 is connected to the glue roller with a roller 6.. The device works as follows. First, the staves 4 are raised together with the roller 42 and left in the indicated position. When this gear 50 on the shaft 46 is separated from the teeth of the gear 10 of the roller 6. Then the glue 3 is poured into the bath 2 at a predetermined level so that the lower part of the roller 6 is immersed in it. After that, a one-time adjustment of the mechanism is performed by rotating the glue by turning the screw 36, which abuts against the protrusion 33, while the upper plate 24 rotates on the shaft 25, which due to the interaction of gears 29 and 30 rotates the lower plate 23 according to a given adjustment. In this case, the adjustment is. Tina 23 was in contact with the roller 6, and the screw 36 would abut against the protrusion 33 on the plate 24, which at the same time remains slightly spring-loaded in its direction by means of the spring 35, In the indicated position, i.e. when the plate; 23 lies on the roller 6, the end of the upper plate 24 on the side of the notches 32 slightly raises the mounting level of the cover 4, with its lowered position and pressing the plate 24 from above to the level of the hook 4, the lower plate 23 rises, i.e. separates from the roller 6 with a predetermined gap on the nauseous passage of adhesive passing between the raised plate 24, remaining on the roller 6. Thus, the adjustment of the adhesive feed mechanism is completed. Due to the fact that the lifting of the plate 23 is connected with a fixed point of position of the ends of the projections of the plate 24 relative to the horizontal plane of the key 4, the subsequent similar adjustments are excluded regardless of the different thickness of the blanks. The cover 4 is lowered into the working position. The gear wheel 50 of the roller 42 engages with the teeth of the stern 10. Then, using the screw 48 and the handwheel 49, lift the bracket 43 in the guide of the bracket 47 according to the thickness of the blanks 19, which are intended to be coated with glue. In this position, the plate 38 under the action of the spring 40 is lowered in the direction of the plate 24, while its protrusions 39 are included in the top 32 on the upper plate 24. The device is ready for operation. An electric motor 51 is turned on, which through a worm gear reducer 53 ,. The wap 54, belt drive 56, the envelope pulleys 1 1 and 55, rotate in the direction of movement (indicated by the arrow) into the roller, 7, 6, 6. Together with the roller 6, gear 10 also rotates, which is in a Lenin hook with gear teeth 50 , rotates in the course of the transfer of the latter together with the shaft 46 of the roller 42 in the sleeves 44 and 45. Thus, the roller 6 rotates, spreading glue. In this position, the bottom plate 23 removes the glue into the bath 2 due to its contact with the surface of the roller 6, while the ends of the upper plates (comb) 24 remain elevated, being several Bbmie crusty levels 4. Corna To the width of the workpieces 19, the slider moves 15 along the guide 46 of the strut plate 14 together with the restriction plate 17, after having loosened the screw 16, while the applicator 20 contacts the roller 6 and removes the adhesive from the specified area on the roller 6, leaving it in the area according to the width of the workpiece 19. In moment to reach As the blank 19 of the glue roller 6, the upper plate (comb) 24 is pressed down, which, due to the interaction of the gear 29 and 30, the lower plate 23 rises to a predetermined distance, which ensures that the glue on the roller 6 is preserved at the same time On the roller 6, the first end of the workpiece is raised against the bottom plate 23 I and lowering the top plate (comb) 24, which causes the workpiece to be fully coated with glue, while the workpiece itself, ensuring that the plate is pressed down (combs) 24, Controls the duration of the glue falling onto the roller 6 by raising the plate 23 until the moment of billet projection From the zone of installation of the glue feeder. As the workpiece 19 passes between the rollers 6 and 42 under the action of the spring 35, the plates 23 and 24 (comb) take on a newly-initial position, i.e. the plate 23 is lowered onto the roller 6, and the plate (comb) 24 on the side of the notches 32 rises, causing the protrusions 39 on the plate (comb) 38 to enter the grooves 32 on the plate (comb) 24. The device is ready for spreading the next workpiece with glue. Thus, due to the fact that the device is equipped with an glue supply mechanism at a given moment of passage of material, which simultaneously serves to adjust the thickness of the glue roller supply, all means for lifting the upper roller are eliminated and the device is simplified, the device’s operation and service life are improved. .
