SU1343448A2 - Machine for sz-twisting of long-size articles - Google Patents

Description

production of cables, namely, machines for SZ-twisting elements of cable products and is an improvement of the device according to the main author. St. No. 1277219.

The purpose of the invention is to increase productivity by reducing the imbalance of the rotating parts, which affects the length of the transition section when changing the direction of twisting of the product. In FIG. 1, an SZ-twisting machine of a long product is shown, a general view, FIG. 2 - a head for twisting a long product with a two-arm rocker and a drive; Fig "3 - constructive implementation of the two shoulders of the rocker and its cross-section.

The machine contains the delivery devices 1 installed in the technological sequence, the input caliber 2 j two spaced apart from each other at distance B are kinematically connected with each other and with the rotation drive 3 relative to the axis coinciding with the axis of long-length product 4, head 5 for twisting item B each of them are swinging about the axis of rotation 6, perpendicular. the rotational axis of the head, the yoke 7 5 each has two grooves for guiding the product j located between the rocker on the axes 8 symmetrically with respect to the swinging axis of the rocker arm of the guide rollers 9 and mounted on the axes 10 fixed on the rocker arm symmetrically relative to its axis rotation, twisting rollers 11 in the axis of symmetry of the grooves of which are located in the plane passing through the axis of rotation of the head for twisting a long article. The machine also has a mechanical gear 12 associated with the rocker-switch position system 13, an output caliber 14 tons 15 and a receiver 16 devices.

Each yoke 7 is made in the form of a cylinder 17 (Figs. 2 and 3) with an axis of symmetry coinciding with the axis of swing. In the body of the rocker arm two grooves 18 are made symmetrically with respect to the axis of swing and 188 . Mechanical transmission 12 is made in the form of a gear wheel 20, coaxially

a rocker and a gear rack 21 hooked to it, kinematically connected with the rocker actuator 22.

Fig, 2 shows the head 5, in which the yoke 7 by means of a mechanical transmission 12 is rotated by an angle of oC-, due to which the uncoupling of the product 4 with the rollers 9 and 11 is achieved,

The cylinder 17 (Fig. 3) has an extremely small structural dimensions, sufficient for making grooves in it

Maschina works as follows.

After refilling the product and setting the rocker arms 7 to the position shown in FIG. 1, the drive 3 of rotation of the heads 5 is turned on and at the same time the drives of the traction 15 and the reception 16 devices (the drives of the traction and reception devices are not shown). These drives remain switched on during the operation of the machine. Due to the frictional forces between the rollers 9 and 11 rotating together with the heads, and. the product rotates in the region between the inlet 2 and the outlet 14 gauge. Due to the calibers in zone A, the product is twisted in one, for example the right directionJ and in zone B in the left direction.

The right-handed product 4 fills the storage zone B, and the left-handed direction rolled through the traction device 15 onto the drum of the receiving device 16. Both heads 5 rotate synchronously in the same direction, therefore, the product does not twist in zone B.

When the accumulation zone B is filled with the twisted product, the software device 23 included in the rocker arm switching system 13 instructs the actuator 22 to rotate the rocker arms counterclockwise at the same time.

When turning the rocker arms at an angle c, the twisted product comes out of engagement with rollers 9 and 11 and freedoms

but passes through the head 5 in the receiving device 16.

After the entire portion of the twisted article leaves the zone B and is filled with untwisted blanks 24, the software device 23 commands the actuator 22 to rotate the rocker arms clockwise, and the cycle of operation of the machine is repeated.

Reducing the time required to change the direction of rotation of the twist of the product, and, consequently, increasing the productivity of the machine is achieved by performing a loop with twists placed in it23 P Y5 It 1 2021 II

rolling rollers in the form of a balanced cylinder whose axis coincides with the swing axis of the rocker arm. In addition to increasing speed, the proposed shape of the rocker allows you to eliminate shocks in the mechanical transmission elements at the moments of changing its position.

Testing of the machine in the production of a desparate bundle of telephone cable showed the possibility of increasing productivity by 1.5-2 times.
