Description

The invention relates to packaging equipment and can be used for packing in boxes of small loose items, such as buttons, fasteners, sweets.

The purpose of the invention is to simplify the design, ensuring the packing of the material in different types of containers.

An introduction to the design of an electromagnetic cam clutch allows you to quickly turn off the bulk material feed mechanism and move the filled box away from the loading point.

Figure 1 shows the device, front view; 2 shows section A-A in FIG. one ; in fig. 3 is a view B in FIG. one; figure 4 - scoop-skip scheme with the image of the trajectory.

A device for metering and packing bulk materials contains a hopper 1 with a groove 2, a drive mechanism for feeding bulk material. The material feed mechanism includes a feeder 3, a shaft 4, a drive-electric motor 5, a worm to 6 and a worm wheel 7 mounted freely on shaft 4. On a shaft 4, a cylindrical gear wheel 8 and a cam-clutch electromagnetic mounted on a gear 8 are freely mounted on a bearing. an electromagnetic part consisting of electromagnets 9 with cams 10, the cams 10 being wholly made with gear gear 8, and a mechanical part consisting of cams of coupling half 11 attached to the sliding pins 12 with springs 13 to the worm th wheel 7. The shaft 4 is mounted splined pin 14 engages with cams yuschiys 11. Feeder coupling half 3 is pressed against the top of the device platform 15. Under spring feeder 3 can be fitted in between

the hopper 16 on the flexible element 17 and is connected to the shaft 4 by means of a connecting rod 18 and an eccentric 19,

Under the intermediate hopper 16, a weighing platform 20 is installed with a counterweight 21, a contact sensor 22 and a return spring 23. At the weighing platform 20 for moving the boxes 24 there is a shutter 25 with a rack 26 for interacting with the gear gear 8. A shutter 25 is attached to the front 27 and back 28 dogs,

In front of the weighing platform 20, a device 29 is installed to feed the boxes where the locking cam 30 is fixed. For the weighing platform 20, an additional platform 31 for receiving the boxes is installed, the latter is equipped with a contact sensor 32. The loading hopper 1 is fixed between the fixed stop 33 and the spring 34. The device is in place boxes may contain scoop-skip 35, the latter is installed on the rollers 36 m 37. The rear roller 37 is freely placed in the groove 38 of the rail 26.

The device works as follows.

The feed bulk material flows through the feed hopper 1 to the feeder

3mechanism feed material. When the start button is pressed, the motor 5 is turned on, the rotation of which is transmitted through the screw pair, the pins 12 to the cam half coupling 11. The latter is in engagement with the shaft 4 by means of the key pin 14.

The rotation of the cam half coupling 11 is transmitted to the shaft 4 and mounted on the last feeder 3, the feeder 3 blades captures the bulk material and drops it through the intermediate hopper 16 into the box 24 installed on the weighing platform 20, After filling the box, the latter together with the weighing platform 20 outweighs the counterweight 21, this closes the contact of the sensor 22 and turns on the electrical power supply circuit of the electromagnetic cam clutch. The cam coupling half 11 of the mechanical part is drawn into the electromagnetic part, and it is disconnected from the shaft key pin 14.

4 and the rotation of the feeder 3 is stopped,

The cams of the cam half coupling 11 engage with the cams 10 of the electromagnetic part. The rotation from the electric motor 21 is transmitted to the cylindrical gear gear 8, thereby receiving movement of the gear rail 26 with the shutter 25, and the pawl 28 moves the two boxes along the weighing platform 20. The front is filled with loose

material enters the platform 31 (or conveyor), and the rear - under the neck of the intermediate hopper 16, while the end of the rail 26 acts on the contact sensor 32.

The latter opens the electrical supply circuit of the electromagnet 9, electromagnetic cam clutch, the attraction disappears and the cam coupling half 11 under the influence of the springs 13 rises

0 is up and locked with the shaft 4 via the key pin 14.

The rotation of the gear wheel 8 is stopped, and the rotation of the feeder 3 is resumed to load the set box.

5 24, at the same time the spring 23 returns the rail 26 with the shutter 25 into the initial position. Moreover, the pawls 27 and 28 are deflected along the course and slip. In the initial position, under the action of the springs, they take a position perpendicular to the curtain 25 and fix two boxes. The second box comes from the box-feeding device 29, since the rear end of the rail acts on the locking cam 30, po5 turns it. The latter passes one box onto the weighing platform, straightens out and fixes the box next to it. The cycle of operation is repeated.

In the case of material jamming between the blade of the feeder 3 and the chute 2, the spring 34 is activated, the chute 2 is retracted along its axis and the jamming disappears. During rotation of the shaft 4 with the feeder 3, the eccentric 19 through the connecting rod 18 acts on

5 intermediate hopper 16, which contributes to the uniform distribution of the material in the box.

If instead of boxes 24 a scoop skip 35 is installed on the weighing platform, then
