SU526559A1 - Suspension for overhead conveyor load - Google Patents

Description

one

The invention relates to the mechanization of moving hangers on an overhead conveyor primarily for use in surface preparation lines and coating products.

Suspensions for the overhead conveyor's cargo are known, made in the form of a lever-articulated system of the Nuremberg type of scissors, which are equipped with rollers that interact with copier tires 1, 2. The use of such suspensions is complicated by the fact that the cargo carriages can move on drive and non-drive sections of the track, on which The device of copier tires is associated with a high consumption of metal and installation work, especially on conversion arrows.

Also known suspension for cargo overhead conveyor, including traverse carriage, which is fixed to the rod with the locking device and lever-articulated system type Nuremberg scissors, equipped with rollers, interacting with the copier tires installed in the places of lifting and lowering loads 3.

The locking device keeps the suspension in a compressed position when transporting it along the route and frees up between the descent and the lifting of the load.

However, the loads moved by such a suspension approach each other when the track is rotated, which does not allow reducing the pitch between the suspensions. In this case, only two levels of the load height are provided throughout the conveyor route, the load position adjustment elements are absent, which does not allow for the exact height position of the load at each predetermined level.

The aim of the invention is to reduce the approach of the suspensions when turning the conveyor track.

For this, we offer a suspension bracket mounted on the traverse carriage.

In addition, in order to provide the required accuracy of the load position in height at several levels, the suspension can be equipped with an additional rod with adjustable stops, and the locking device is made in the form of a slide, a hinge connected to a lever-articulated system and provided with a hinged clip on it hook, interacting with regslirovaniem stops additional shtangi.

FIG. 1 shows the proposed suspension, side view; in fig. 2-motion suspension on the turn in the plan; in fig. 3 - suspension lifting mechanism; in fig. 4 - view from

arrow A in FIG. one; in fig. 5-12 - the interaction of the hook with adjustable stops and the movement of the links of the Nuremberg scissors in the place of lowering the load; in fig. 13 and 14 - copier tires.

The traverse 1 of the traverse carriages 2 cantilever symmetrically with respect to the axis of the chain 3 of the conveyor 4 in the direction of its movement is attached to the rod 5, on which the slider 6 is fitted, equipped with rollers 7 and pivotally connected to a Nuremberg scissors 8 type suspension bracket.

An additional rod 9 is fastened to the traverse 1 parallel to the rod 5, on which adjustable lugs 10 are mounted, one of which is engaged with the hook 11 of the bracket 12 which is hinged to the slide 6 and provided with rollers 13.

Lever-articulated suspension system type Nuremberg scissors 8 is mounted on a fixed axle 14, placed on the crossbar 15, connecting the rod 5 and the additional rod 9. To the monorail 16 in the places of load lifting fastener tires 17 are mounted, and in places of descent - copier tires 18 .

The backup tire 17 is provided with tracks 19 for rollers 7 and tracks 20 for rollers 13. Dorozas 19 consists of a section 21, a horizontal section 22, an inclined section 23, a parallel section 21, a horizontal section 24, and a reverse section 25 in the direction of movement of the node suspension. Track 20 is parallel to sections 21 to 23 of track 19.

The copier tire 18 is provided with tracks 26 for rollers 7 and tracks 27 for rollers 13. Track 26 consists of a section 28, a horizontal section 29, an inclined inclination section 30, a horizontal section 31, and a reverse incline section 32 that are parallel to the section 30. A track 27 consists of a section 33, inclined in the direction of movement of the node suspension, parallel to the section 28 of the track 26, and a section 34 with a reverse bias, parallel to the sections 30 and 32 of the track 26.

When the track of the conveyor 4 is rotated to either side of the yoke 1, it is located tangentially to the axis of the chain 3, as shown in FIG. 2, the gap between the weights being reduced by the smaller, the larger the cantilever-distance from the center of the link of the chain 3 located between the traverse carriages 2 to the axis of the rod 5.

In place of lowering the load, the rollers 7 of the slider 6, hit the inclined sections 28 of the tracks 26 of the tire 18, squeeze the slider 6 down the bar 5, as a result of which the Nuremberg scissors 8 are somewhat compressed, and a vertical clearance is formed between the adjustable stop 10 and the hook And.

Then the rollers 7 go to the horizontal sections 29 of the tracks 26 and until the rollers 13 hit the inclined sections 33 tracks

27 all links of the mechanism do not change their position relative to each other.

After hitting the inclined sections 29 of the track 27, the rollers 13 start to move down, and the rollers 7, continuing to move along the horizontal sections 29 of the track 26, are held at the same height, as a result of which the bracket 12 rotates around the axis of the rollers 7 clockwise and between the hook 11 and the adjustable stop 10 form a horizontal gap (see FIG. 7).

Then the rollers 7 are transferred to the areas 30 with the reverse slope of the tracks 26, and the rollers 13 to the parallel sections 34 with the reverse slopes of the tracks 27.

In the process of moving the rollers 7 and 13 along sections 30 and 34 with a reverse inclination, upward movement of the slider 6 along the rod 5 occurs, the Nuremberg scissors 8 are pulled out and the transport load is lowered.

In this case, the bracket 12 does not rotate relative to the axis of the rollers 7 and the previously formed horizontal gap between the hook

An adjustable stop 10 allows, when moving upwards, the hook 11 to avoid its collision with the adjustable stop 10.

After the end of the lowering of the load, the rollers 13 begin to go along a smooth curve with

tracks 27, and the rollers 7 go to the horizontal sections 31 of the tracks 26, as a result of which the clamp 12 rotates counterclockwise around the axis of the rollers 7 (see FIG. 9) until the hook 11 stops in the adjustable stop

10 (see FIG. 10).

After moving the rollers 7 to the inclined sections 32 of the tracks 26, the slide 6 is moved upwards along the rod 5 and the clearance of the vertical clearance between the adjustable

stop 10 and a hook 11.

After selecting the gap, the slider 6 stops moving up and takes, and with it, the entire suspension, a new fixed position in height, specified by the position of the adjustable stop 10 (see Fig. I).

After exiting the engagement with copier tire 18, before engaging with the next copier tire 17 or 18, the suspension and

The transported load does not change its position in height (see Fig. 12).

When lifting the load in the place of interaction of the rollers 7 and 13 of the suspension with a copier tire 17, the order of movement of individual links is similar to the described interaction of the rollers 7 and 13 with the copier tire 18.

The proposed device allows to significantly reduce the gap between the cargoes, ensuring at each level of the conveyor the necessary accuracy of the position of the cargo in height, thereby significantly reducing the length of the process line and each unit entering it. This leads to savings in space, energy efficiency, working resources,

reduce the weight of the aggregates.
