SU42267A1 - Device for installation of the take-up rolls of the glass-blowing machine of the conveyor type - Google Patents

Description

On glass-blowing conveyor-type machines, a stream of hot glass melt is fed from the feeder through rolls to the machine’s take-up conveyor. At the same time, the tape is being produced with a hot roll. Clomas, in order to save waste glass, has a round band, thicker than the connection tape. The booms are so large that they can be blown out of this glass product.

One of the conditions for the correct formation of glass products on the machine is the accurate and uniform supply of hot glass mass to the platform of the machine’s take-up conveyor so that the boxes lie precisely on the blowing holes in the platforms of this conveyor. In order to adjust the exact match of the blows to the blow holes on the conveyor on the machine, the take-up rolls are usually supplied with a differential gear with a device for producing relative shifts around the rolls.

However, practice has shown that this measure does not eliminate the uneven running of the tape as it leaves the rolls, since the outgoing tape, due to inertia and adhesion, for a short period of time follows the right roll, i.e. the roll, which the tape is turned over to go to

acceptance conveyor. In this case, the tape goes with uneven bends, which creates its unstable course, which is extremely harmful for the process of manufacturing products.

From the practice of working of this type, it became known that if the right roll is raised above the left, then with the correct combination of roll heights to the receiving conveyor, the output is w, and the tape gets a fairly steady move.

However, until now, the problem of roll design, which would have, in addition to the existing adjustments, e, e, and the ability to conveniently adjust the vertical positions and deflections from the horizontal, without disturbing the coupling of the drive elements and operating the machine, has not been solved.

The proposed device is intended to eliminate the listed disadvantages in the design of the rolls. This is achieved by the fact that the take-up rolls are installed in double frames, with the upper frame carrying the take-up rolls resting on four points of the main lower frame. The points of support on the main frame can be moved in the vertical direction with the help of two hand drives to the jacks supporting the upper frame, so that it is possible to raise and lower

rolls or raise the right roll above the left. The pointer at the same time indicates the deviation of the rolls from the horizontal.

The drive elements of the rolls are in the lower frame, and against the disengagement of the drive gears of the rolls, during vertical adjustments, the fixed axes of the rolls are connected by two t with points coinciding with the axes of rotation of the drive shaft running parallel to the axis of the rolls. In addition, the support points of the frame with the rolls have a spherical shape. These ball bearing points fit into the horizontal cylindrical grooves of the upper frame so that the frame with the rollers can move freely during adjustments, but not rise from the points of support under the action of the drive load.

In FIG. 1 is a front view of the fixture for mounting the take-up rolls of a conveyor-type glass blower; FIG. 2 - view from above; FIG. 3 is a vertical section along a-b-c-d-e-f-g-fi of FIG. 2; FIG. 4- front view of the frame support with rollers; FIG. 5 is the same side; FIG. 6 is a diagram of the installation of the take-up rolls.

The main frame / rolls on the rollers associated with it can move on rails mounted on frame 2 of the glass-blowing machine. On the main frame 7, drive mechanisms are installed, i.e. differential gear 3 and gear 4 from the drive shaft 29 of the machine and also a set of gears 25, 26 from the differential gear of the planetary gear coupled to the rack 5 mounted on the frame /. The longitudinal shifts of the toothed rack are controlled by the relative shifts around the circumference of the rolls b and 7 to obtain a match in the glass mass tape with the holes in the receiving conveyor / 5 platformochki.

To raise and lower the take-up rolls 5 and 7, the latter are installed in a separate frame 8, which rests on the ball ends of 9 spindles 10 of four jacks / 7 (Figs. 1, 4 and 5). In order for the frame with rollers to move freely during adjustments and not to be separated from the jacks under the action of the load of the drives, the ends of 9 W spindles are sharpened in the shape of a ball and placed in horizontal cylindrical channels in the lower part of frame 6, and the ball end of the spindle in the channel has a groove 21 having an o-shaped section. A pair of left and a pair of right jacks have manual drives / 2, so that the right and left side of the frame with rollers can be raised and lowered separately with respect to the line of passage of the receiving conveyor 75 (Figs. 1, 2 and 3).

With a horizontal position in the same plane of the axes of the rolls, hot glass mass 74 is transferred from the rolls to the receiving conveyor by bends, as shown by dotted line 75 (Fig. 1).

With the same properly adjusted slope and with the appropriate height of the rolls, a smooth transition of the hot glass ribbon strip to the receiving conveyor is obtained, as shown by the dotted line 75 in FIG. 1 and 6).

The deviation of the axis of the rolls from the horizontal axis indicates the index pointer 77 (Fig. 1), which serves to empty the rolls b and 7 angles. between the two rims 78 and 79. The axes 27 and 2S of the rolls 7 and 5 are stationary, and the rollers with gears rotate on them. To clarify the position of the rolls with respect to the axis of the stream of hot glass mass flowing out of the feeder / 4, a coupling 20 with a right and left thread mounted on the roll sheath serves.

All of these adjustments do not prevent the thickness of the tape being calibrated with the help of a manual drive 22. As well as the rolls self-dissipation, when a solid comes in together with the glass mass between the rolls, the lever device with a load 23 does not block. Rail route 24 of the receiving conveyor 73, passing under the rollers and arcuate crossbars 30 of the bed 2 during operation and movements of the machine relative to the rolls (Fig. 3).

By using the described installation for setting the rolls,
