(54) WEIGHT-MEASURING DEVICE

one

The invention relates to weighing equipment, in particular to weighing devices that are embedded in production lines.

A weight measuring device is known, which contains a weighing mechanism, a movable and fixed comb with teeth oblique in the direction of movement, hingedly mounted on a fixed comb, and tacks with seats in the form of hollows under the article GO.

However, the device cannot be used for weighing large loads, for example, boxes moved by a chain conveyor.

The closest in technical essence to the proposed invention is a weight measuring device containing platform scales integrated in a chain conveyor, a lifting device and an orientation mechanism for a load relative to the platform of a balance with a drive 23.

The known device does not have the necessary reliability and has a limited field of use, since its loading is possible only during the transportation of goods. Loading from conveyors located perpendicular to the main one is impossible. The purpose of the invention is to increase the reliability of the device and expand its use. .

The goal is achieved by the fact that in the device the load-lifting device is made in the form of carriages located in vertical guides with load brackets and with a bolster for its fixation in the upper position and a coil with ribs — stops mounted on an axis fixed on vertical guides and fitted flanges, between which rollers are arranged in pairs and in the upper of which there are hollows for balls, 3 vertical guides spring-loaded and fixed, and the load orientation mechanism is made in the form of th An articulated arm with a spring-loaded lever mounted on it, mounted in a horizontal rail, installed between vertical guides and mounted on the frame of the platform scales.

The device contains a load receptor 1, a mechanism 2 for orientation of the loads relative to the platform 3.

The load receptor 1 consists of vertical guides 4 for the carriage 5, having a roller 6, two brackets 7 and a support 8. On the vertical guides 4 on the axis 9 (Fig. 3) there is fixed the coil 10, which has edges 11, the upper flange 12 and the lower flange 13, between which four rollers 15 are mounted on axles 14.

Two sockets, made in vertical guides 4, are laid on the ball 16, which are pressed against the flange 12 of the coil 10 by the springs 17 by means of adjusting screws 18 (Fig. 4).

The load orientation mechanism 2 is made in the form of a slide 19 (Fig. 6), on which the lever 20 is fixed by means of a bracket 21, an axis 22 and a spring 23. A slide I9 is mounted in a horizontal guide 24 (Fig. 1), which is laid inside vertical guides 4 and fixed to the frame 25 weights. The slide connecting rod 26 and crank 27 is connected to the drive 28.

On the frame 25 there is a limit switch 29, and on the chain conveyor 30 a limit switch 31. On the conveyor belt 30, platforms 32 are attached to drawers 33 in which the load, such as yarn, is transported.

FIG. 1 shows the initial position of the device in which the slide 19 is in the extreme right position and the carriage 5 at the bottom is supported by the roller 6 and the horizontal section of the slide 19

The device works as follows.

When the chain conveyor 3 is turned on, the CRT 33 is fed for weighing. Box 33 acts on the limit switch 31 and turns off the drive of the chain conveyor 30, and the drive 19 connects to the power grid.

Crank 27 makes a revolution, at the end of which it acts on the end switch -29, which turns off the drive 28. During this time, slide 19 makes in the guide 24 moving to the leftmost position and turns back. When the slide 19 is moved to the left, the roller 6 rolls along the inclined part of the slide 19 and lifts the carriage 5. The brackets 7 pass between the links of the platform 32, rest against the bottom 5 of the drawer 33 and lift it above the conveyor 30. When the roller b rolls out onto the horizontal section of the slide .19, the spring-loaded lever 20 will interact with the coil 10. With its notch, the lever 20 rests on the roller 15 of the coil and rotates it about the axis 9 by 90. Spring-loaded balls 16 fix the coil 10 in a new position of the Institute. At the end of the turn, the rib-stop 1I of the coil 10 will be under the subclass 8 of the carriage 5. The movement of the slide 19 to the left is over. Now it will move back to its original position. The roller 6 of the carriage 5 rolls along the horizontal section of the slide 19, then moves to the inclined section, and here the carriage 5 with the cap 8 is pressed into the edge-support 11 of the katzgka 10. The carriage hangs in the guides above the slide 19, which goes out from under the roller 6 of the carriage to the extreme right position, the Box 33 together with the carriage 5 vertical guides 4 will be on the weighing platform. The weigher weighs the load, presses the power button on the actuator 28 of the device; crank 27 will make a full turn and stop; slide 19 will make a returnable movement. When moving to the left, the top of the inclined section acts on roller 6 and slightly lifts box 33, carriage 5 and plate 8 above the rib 11. When roller 15 leaves the horizontal part of hill 19, spring-loaded lever 20 interacts with coil 10. By its notch 20 rests on the reel roller I5 and rotates it around the axis 9 by 90. The sprung balls 5–16 fix the coil 10 in the new position. At this turn, the coil reamer 11 goes out from under the subgun 18. Now when the slide 19 moves to the right extreme position, the roller rolls first along the horizontal, then along the inclined sections of the slide and stops at the lower horizontal section of the slide 19, and the box 33 lowers onto the platform 32 of the conveyor 30, and the brackets 7 lower under the chain conveyor web. At the end of the rotation crank 27 acts on the limit switch 29, which turns off the drive 28, and the drive conveyor Zi connects to the mains. With the launch of the conveyor 30, the next box arrives for weighing. Technical and economic efficiency is due to the positive effect, which is to increase reliability, simplify the transportation of goods, the possibility of weighing goods at the perpendicular location of the supply and from the water conveyors to the main, saving the area, simplifying the maintenance of the device.
