Description

The invention relates to a machine tool industry, in particular to the discharging devices of automatic lines and machine tools.

The purpose of the invention is to increase the reliability and performance of the unloading device by reducing the number of intermediate orienting movements of parts.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. 1 (view of the conveyor arms and the turning parts of the slab before and after the turn); in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 1 (stripper strips are shown in the lower and upper positions before the turn); in fig. 5 is a view of FIG. 2 (plates with strips mounted on them are shown in the upper unlocked position before turning); in fig. 6 is a view of D in FIG. 5 (bottom view of the turning parts of the plate); in fig. 7 and 8 - sections E-E and MF in FIG. 5 (along guide rails mounted on the plates); in fig. 9 is a section view of FIG. 6 (plate in the lower position); in fig. 10 is a view of K in FIG. 5 (top view of the stove).

On the base 1 of the device there are rolling pins 2 associated with a vertical displacement drive (not shown). Parts 3 and 4 of the composite plate are fixed on rolling pins 2, and strips 5 are installed in part 3, 5 shatunov b, and on the rotary part 4 - strips 7 are removed from connecting rod caps 8. Slats 5 have a cutout that repeats the shape of connecting rod 6, and stripper strips 7 have a cutout that repeats the shape of cover 8. Stripper strips 5 and 7 are designed to remove parts (connecting rods) 6 and 8 from rods 9 of the main conveyor of an automatic line (not shown), moreover, at the stage of lifting skalok 2, they perform the functions of knock-ons (Fig. 3 and 4), and at the stage of colliding parts (Fig. 2 ) - guiding elements.

The axes 10 and 11 of the stripper strips 5 and 7 are mounted in parts 3 and 4 of the plate on bearings 12 and equipped with gear wheels 13 and 14 of the same diameter, interconnected by intermediate gear wheels 15, which sit on axis 16 in parts 3 and 4 plates.

The axes 10, which are the axes of rotation of parts 3 and 4 of the plate, are fixed in rolling pins 2. Between the strips 5 and 7 on the parts 3 and 4 of the plates there are guide plates 17 and 18 rigidly attached to the latter, in which notches are made 19 and 20 in the form of strips 5 and 7.

Portal 21 contains mechanisms 22 of rotation, equipped with forks 23 and 24. On the fork 24 is fixedly fixed pin 25, periodically in contact with a spring-loaded lock 26 installed in the housing 27 mounted on the part 4 of the plate. Part 3 of the plate is provided with a hole 28 and a slit 29.

Portals 21 also have ejectors 30 and 31 for pushing parts 6 and 8 into the discharge conveyors 32 and 33.

The rods 9 of the main conveyor feed parts 6 and 8 to the unloading position. At this time, the plate, consisting of two parts 3 and 4 with strips 5 and 7 mounted on them, is in the lower position under parts 6 and 8, and parts 3 and 4 of the plate are interconnected

a retainer 26 located in the hole 28 of the plate part 3. When lifting skalok

The stripper plates 5 and 7 remove from the rods 9 of the main conveyor parts 6 and 8, which, when lifted due to the displacement of the center of gravity relative to the points of contact with the stripper planes 5 and 7, are rotated (Figs. 3 and 4). At the end of the lift, the guide plates 17 and 18, which are fixed relative to the turning parts 3 and 4, enter the forks 23 and 24 of the turning mechanisms 22 and the tongue 25 squeezes the spring-loaded clamp 26 from the hole 28 by the forks 23 and 24 in contact with the fixed Parts 3 and 4 of the plate with guide plates 17 and 18, turn parts 3 and 4 of the plate clockwise 90 ° (Fig. 2, arrow L), with pin 25 turning with the fork 24 and part 4 of the plate from the hole 28 in part 3 of the plate through the slot 29. When you turn parts 3 and 4 of the slab plate-off trucks 5 and 7 and gears 14 mounted on axles

5, 10, the pivot axes of the plate parts 3 and 4 remain stationary, and the gear wheels 15, rolling around when the plate parts 3 and 4 rotate around the gear wheels 14, rotate the gear wheels 13 fixed on axles 11, as well as strips 5 and 7 fixed on these axes are counterclockwise with respect to parts 3 and 4 of the plate at the same angle of 90 ° (Fig. 2, arrow M), since the gear wheels 13 and 14 have the same diameter. After turning parts

The 3 and 4 plates of stripper strips 5 and 7, fixed on axles 11, together with stripper strips 5 and 7, fixed on axes 10, and guiding strips 17 and 18, form common guide trays separately for connecting rods and connecting rod caps, because

The cuts are the same for all stripper strips and guide strips installed on one part of the plate.

In these trays, the parts 6 and 8 by the ejector 30 and 31 are shifted to the discharge conveyors 32 and 33 (Fig. 2, arrow H). Then

5, the ejectors 30 and 31 are returned to their original position, and the mechanisms 22 of rotation by forks 23 and 24 rotate the parts 3 and 4 of the plate in the opposite direction, i.e. against the clock

arrows at an angle of 90 °, with pin 25 in contact with latch 26 extending into slot 28 of plate 3 of part 3 through slot 29. With this rotation, gears 15 roll around gears of stationary gears 14 13, strips 5 and 7 fixed on these axes and also fixed on these axes clockwise relative to parts 3 and 4 of the plate at an angle of 90 °, thereby returning strips 5 and 7 to their original position relative to parts 3 and 4 plates.

During the downward movement of the rolling pin 2, tongue 25 clears the clamp 26, which enters the hole 28 of part 3 of the plate, thereby joining both parts of the plate into one; after that, the plate is lowered to its original position.

Due to the fact that in the proposed device the same strips are strippers at various stages of the device operation

five

perform various functions, namely removing, turning and guiding elements, then in comparison with the known in the proposed device, the number of orienting movements of the workpieces is reduced. Reducing the number of orienting movements allows reducing the number of sequentially and in parallel operating mechanisms and hydraulic and electrical equipment, and as a result of this, reducing the number of equipment failures, which increases the reliability of the proposed device. By reliability is meant trouble-free operation of the device for a long time. Improving reliability reduces the amount of downtime for automatic equipment due to the fault of this device, which increases the amount of time actually worked, and ultimately the performance of all automatic equipment.
