SU36000A1 - Machine for the manufacture of conical wood, equipped with a central channel plugs - Google Patents

Description

When paper rolls of finished paper rolls (newsprint, mouthpiece, etc.) are removed from the paper machine into the hole of the roll, where the axis is placed / they are usually driven in at both ends by a special wooden plug in the form of a hollow truncated cone. Using these plugs at the place of consumption of paper (for example, in printing houses) the roll is placed on the printing press. The manufacture of these plugs is usually done manually on primitive lathes on wood, resulting in high costs and low productivity, which sometimes limits the delivery and shipment of finished paper products to consumers.

The proposed design mechanizes the whole process of manufacturing these plugs in order to increase labor productivity and reduce the cost of the plug.

According to the invention, a disk is used in the machine, which receives periodic turns and is provided with a series of holes in which the billet is inserted into blanks, pre-cut and machined into a cylindrical shape on the same machine. In the workpiece fixed in the disk, a central hole is drilled, after which the workpiece, with successive rotations of the disk, comes first to unfold this hole to the reamer and then (130)

those to the ejector, which transfers the workpiece to the headstock for decorating it outside on the cone.

Mechanisms for cutting and feeding the workpiece to the disk, for turning the disk and for ejecting the workpiece and turning on the cone, have movements consistent with each other, as a result of which the whole process of manufacturing the cork passes automatically.

On the base / proposed machine (fig. 1-3) there are racks 2, 3.4, 5 l 6, in the bearings of which the main shaft 7-8 and crankshafts 9 and 70 are placed. Shaft 7- is driven by a belt drive gears, worn on the idler and working pulleys 12. From shaft 7-8, rotation is transmitted through two bevel gears 13 vf 14 to crankshafts 9 and 10. h

.On axis 14, mounted on the machine bed, is placed on the toothed sectors 15 and 16, which rotate the OJ of the crankshaft 9, to which they are connected with the help of tongues 77. Sector 15 is coupled to the slide 18, “with the current charger, and reports this a slide of movement back and forth along the table / carriage along the guide groove 23 (Figs. 1 and 8). The same sector / 5 is engaged with the rail of the headstock 21 (Fig. 8. 9), which moves along the table 19 along the guide groove 22 at the same time with the rails 18. For the possibility of correct and precise adjustment of the stroke of the rails 18 and the headstock 21 of the sectors / 5 and 16, as well as the shaft crankshafts 9 are provided with rocker slits, making it possible to change the shoulders of the shaft curves and sectors. The fastening part of the connecting rod 17 in the groove of the sectors 15 and 16 is shown in FIG. 5 and is made in such a way that along the tail of each sector, a non-through trapezoidal slot 24 is selected, along which the pin 23 can be moved, fixed by nuts 25.

The crankshaft 10, using a pair of gear sectors 26, which are freely seated on the axle 27 and coupled with the rails 28, causes the rear carrier 29 to reciprocally move along the machine table (Figs. 1, 3 and 8). Here also, in order to be able to adjust the lobe of the slide, the cranks of the shaft 10 are provided with rocker cuts. The slide 29 carries a roller with a drill chuck 30, a shaft with a chuck kp sweep 31 and is provided with a hole 32 into which the pusher 33 is screwed. Rotation of the drill 30 and sweep 31 is carried out from the actuator 34-55 (Fig. 1). The pusher 33 (Fig. 7, 8) is a sleeve with an external thread.

in the center of which, on the ball stop 36, the rod 37 rotates, in turn, provided with an axial channel 38 and secured in the sleeve with pins 39, to prevent its longitudinal movement.

On the table 19 of the machine are located in addition to the described devices also (Figures 1-3, 8) boxes of the roller feeding device 40, headstock 41 and 42, in the bearings of which hollow cutting chucks 43, 44, driven by the drive 45 and 46, and two racks 47 48 and guides for the workpiece with a hyper-ebb-out grooved roller, from which the upper rollers rotate in moving bearings spring-loaded from above, and can be lifted by passing the seam through the workpiece.

Feeder 40 is a system of grooved rollers also of a hyperboloid shape, with the help of which the workpiece-poles 49 are directed and fed to the machine. Input 50 And output 57 pairs of feeder rollers serve to clamp the poles 49 when the supply stops and are idle. Prs & m 50 rollers have a smooth surface, and rollers 57 are provided with spikes along their surface. The upper rollers of pairs 50 and 57 are enclosed by their trunnions between two pairs of articulated arms 52 (Figs. 1.6, 8), having a common swing axis 53, and using a system of tufts 54, which are under load 55, and constantly press billet-pole 49 to the lower rollers. The actual feed rollers in the feeder 40 are grooved drive semi-rollers 56 (Fig. 1, 8), which receive rotation from the crankshaft 57 of the crankshaft 9 and associated with them a system of parasitic gears 55. The surface of the half-rollers 56 is filled with a grooved for better adhesion to the feed material. Due to their incomplete shape, the rollers 56 feed the workpiece 49 periodically forward only to the prescribed length of the cork being manufactured. To be able to adjust and establish a certain feed rate, the rollers 56 can be shifted relative to each other at the desired

an angle, for which a gear wheel was mounted on one of the half-rollers, which was fixed on this axis by means of the coupling 60 (Fig. 8), with the spikes of the axis of the half-drum 55 entering the recesses of the gear wheel.

A billet-pole of 49 with the knots knocked out and unevenness is fed by a feeder 40 (fig. 1, 8) into the cavity of the rotating chisel chuck 43, where it is preturned into a cylindrical shape, and then with the rollers of the stand 47 the billet is sent to the cartridge 44, where it is made final turning to the required diameter. Passing the head 44, the billet by the rolls of the stand 48 is guided into the cavity of the storage box b / equipped with a diametrical notch into which the disc tank 62 is automatically lowered to cut from the work 49 the required length of the chock 63. The cut chop 6B rolls along the chute 64 of the storage box ( Fig. 10) and becomes on the axis of the charging of the slide 65 of the carrier 18.

The matnik saw 62 (Fig. 1, 8, 10, 11) is mounted on the shoulder 66, having a swing axis 67 on the rack 68, and is driven into rotation from the cutting tool cartridge 44 through a belt drive 59 and a chain 70. On the free end of the shoulder 66 there is a roller 7 / placed in the cam chute 72 of the slide / 5. When the slide 18 with the charge 55 is retracted (to the right in Fig. 1), the roller 77 slides along the inclined part of the trough 72, thereby lowering the saw 52, in order to cut off the next chock 63 of the stopper from the workpiece 49. Having fallen further into the vertical branch of the trough 72 the roller 77 with the saw under the action of the spring 73 (Fig. 10) rises quickly upward, thereby withdrawing the saw from the cut. When the headstock 18 is moving forward, the roller 77 goes along the horizontal branch of the cholot 72, and the saw is in the upper non-working position. For a better direction and the roll 77 to the inclined 4actb of the chute 72, in its horizontal branch a spring-loaded reverse dog 74 is placed (Fig. II). The ends of the workpiece and the sawn off pieces of the new workpiece, smaller in length than the established length of the chock 65, do not fall on the chute 64,

fall through the vertical channel 75 of the magazine box 61 to the outside

(Fig. 10).

The cut chock 63, when moving the salouk 18, is fed forward by the charge 55 to the hole 75 (Fig. 1, 8, 12) of the disk case 78 and further to the hole in the body of the disk itself, where it rests on spikes 77 specially arranged in each hole of the disk 78 ( Fig. 4, I), preventing the chock 63 from turning. The disk 78 is provided with a toothed crown interlocking with the gear 79 (Fig. 1), which is seated on the keyboard of the SO sleeve, and the paddle is worn on 7-8.

The disk 78 of the pgs circle is provided with eight holes, which coincide with each turn of the disk per Vs revolution, with holes in its casing. There are three holes in the housing (Fig. 12): a hole 75 through which the chocks 63 are inserted into the body of the disk 78 and efe is drilled; with a drill 30 a hole S2 of smaller diameter for the passage of the sweep 31 (Fig. 8, 12, and a hole 81, which the drilled chuck 63 is pushed out of the disk 78 by the pusher 33. (Simultaneously with the charging by the charger 5, the lumps 63 in the hole 78 of the disk 78 meet the sled 29, the drill 30 of which - drills a hole smaller than the diameter required by the choke 63 along its axis , a1, a sweep 57, mounted on a sled 29, at this time is swept The final hole S of the next well-bounded hole 82 82 of the already drilled chock arrives.

The automatic rotation per / g turn of the disk 78 is as follows. On the idler sleeve S9 (Figs. 1, 2), the carbine 83 is freely put on the plug of which the ratchet is placed; wedged on sleeve 5 (and fitted with a spring-loaded pawl 55. The end of the carabiner is pulled down by the spiral spring 86, and beside the carabiner on the shaft 7-8, a leash 87 is jammed with a spring-loaded U1 type 88. When the shaft rotates, 7-8 with the leash 87, the thigh The skiff 88 slides along the plane of the rack 3 and engages with its end coming out of the leash on the carbine 83 (Fig. 2) and turns it around the sleeve 80 until the pin head 55 fits into the notch 89 of the rack 9. Spring dog 85

at this time, it slides along the teeth of the ratchet 84. As soon as the pin 5 against BbieMKH 89, it pulls in with its spring and releases the carbine 83, the latter is pulled down from the pin by the action of the extended spring 86, and turning the ratchet by rotating the dog 84, and with it the sleeve 80 with the gear 7P, which in turn rotates the disk 78 by Vs turn. To adjust the angle of rotation of the disc, the stop 90 serves, and the carbine 83 rests on the bottom during its reverse movement. The turning of the discs;,; / takes place, of course, at the moment when the slide 29 and / 7 dispersed, i.e.

To hold the chocks 63 on the spikes 77 during drilling and when the charger 65 has moved away from the hole 76, the top spring-loaded and provided with a sloped outer bottom end serves; and 91, placed on the disk casing 75 / (Fig. 12).

When the wood chock 63 with the drill 30 already made and the hole swept 57 approaches hole 81 (Fig. 1, 8-12), the bottom 37 of the ejector rod 33 of the slide 29 is pushed out of the disk 78 and transferred to the center 92 of the headstock 2 / (Fig. 9), which is provided with spikes to keep the chock 63 from turning on it. Thus, when approaching the sled 29 and the headstock 2 /, the cork blank 63 (chock) is clamped at the center 92, yen 4Du by the rod 37 of the pusher 33, in the opening 55 of which the center 92 enters, and the sleeve 93 placed in the rack on the ball bearing ( Fig. 9), and so that the akter 37 of the ejector 33 itself, I1 1, has a ball bearing 36 (Fig. 7), then the ends of the chocks 63 during its rapid rotation with the center are protected from damage from friction. The rotation of the center 32 of the headstock 21 is carried out by a belt drive 94 (Fig. 8) from the cutting head 44. When the chock 63 has set its hole on the rotating center P2, at this moment the knife 95, attached to the lever 95 and lowered by the help of st: | 1, with an adjustable articulation 96 of an eccentric 96, stuck on the shaft 7-8 (Fig. 8, 9, 12, 13), Knife 95 turns the chock 63 into a cone, i.e., the last operation, manufacturing a cork.

When the slide 29 and the headstock 21 are dispersed, the stopper is ready to go off the center 92 of the headstock 27 and, rolling down the tray 97 (Fig. 12), falls into the receiver of finished products.

Thus, all the processing and manufacturing operations of the plug on this machine are automated and go one after another in a sequential order. The sled 18 and 29 to the headstock 27 periodically and automatically, in view of the consistency of their movements, come closer and diverge relative to the disk 78 and in the first case, charge, drill, drill and push the chock to the center P2 of the headstock 27 for turning into a cone, and in the second case, trimming from the blank of the chock and dropping the finished cork from the center 92 to the tray 97.

The subject matter of the invention.
