Description

Tubes are made of rubberized fabric. The fabric is coated with rubber glue and manually screwed onto the wooden (conical) mandrel in two layers. In order to glue better, the layers of rubberized fabric on the mandrel are rolled on the cutting edge, then removed from the turf and sent to vulcanization.

The proposed machine excludes manual labor in the manufacture of vegetable pipes, and also increases labor productivity and product quality.

FIG. 1 shows the kinematic diagram of the automaton; in fig. 2 is an end view of the roller rollers: in FIG. 3 - unit for mobile fastening of the mandrel.

The machine consists of five ribbed tapered rollers, 2., which perform the operations of rolling up and rolling rubberized fabric onto the mandrel 3.

To fill the "dead space between the rollers, flat pores 4 are provided, the free end of the |) and pressing the sod, or the roll-in tube, and the other end secured in the clamps 5.

The rollers rotate in one direction with the help of a set of ten sixth gears 6, 7 and 8, from a cat: 1st gear 6 is leading and sits on the same shaft with detachable coupling 9 and pulley 10 connected with electric motor //. The mandrel is fastened in the guide 12 with the help of a 13 m nut bush M. And the guide is attached with bolts / 6 cheek / 5, on which hose 77 is fastened with a tap 18 for compressed air; air through the channel / 9 passages. Ait into the base of the mandrel and through the hole 20 can go outside. The cartridge 21, in which the mandrel is fixed, has a sliding fit in the sleeve Ii, which allows the mandrel to move along the axis. moreover, the displacement is perceived by the spring-loaded frame 22. The axial impulse of the movement of the dorpe is reported by the firing pin 23. The direction of the adjustment 12 is adapted for vertical movement with help of the link 24 and 25 of the current 25.

LI 1241042 Rollers 2 with gears 8 can be rotated through a certain angle, freeing space above the mandrel. The lifting of the rollers 2, the mandrel, the striker 23 and the rotation of the crane 18 are controlled by a camshaft. not shown in the drawing. The fabric 26 for forming the tubes is fed by a conveyor 21, above which the rotary roller is located a cylindrical sector 28, mounted so that it turns to the axis 29 with a moving fabric, while the ball moves on the conveyor belt.

The Oci5 29 sector is kinematically connected to the clutch 9 through the hinge 30 and the rod 31. The apparatus is placed on the frame shown conventionally in the diagram.

When the moving conveyor is not loaded with fabric blanks, the device does not work, since the sector 28 in its position turns off the clutch 9, only the conveyor moves, and all mobile units of the assembly (rollers 1, 2, guides 12 of the mandrel, and the striker 23) are in position, crane 18 is closed.

As soon as the fabric blank touches the sector 28, it turns at a certain angle, turns on the sleeve 9, and along with it includes all the bead rolls and the camshaft cam.

The fabric blank of its own weight hangs down from the conveyor belt, is caught by the rotating rollers and rolls on the mandrel into the tube. iK at the end of the seaming process, the camshaft cams of the shaft start to operate in the following sequence: 1) rollers 2 turn, freeing the space of the mandrel 3 with the tube; 2) guide J2 rises and together with 1 and the mandrel, 3) striker 28 hits the end of the mandrel, shearing the finished tube, and 4) valve 18 opens, air rushes through the opening 20 between the walls of the tube and the mandrel and resets tube through the narrow end of the mandrel. Sector 28, not restrained by the fabric procurement, returns to its original position, the apparatus stops; the conveyor continues to move and the unit continues its periodic operation with a duration of one Nikla 6-10 seconds.

Subject invention

. A machine for the manufacture of vegetable pipes, consisting of a feeding conveyor with a mechanical synchronizer, as well as devices for removing tubular impact-pneumatic type, aggregated with a movable mandrel and five stitch rollers, characterized in that the mechanization of the process of assembling the tubes, The stitching rolls are made with radial grooves that carry elastic reflectors that prevent the material from sticking to the roll surface.
