Description

one

A device for packing hardware into boxes, consisting of a receiving bin, a lift for loading it, a vibrating channel, scales mounted below it, mechanisms for packing boxes and their brands, and a conveyor for moving boxes are known.

The purpose of the invention is to simplify the design of the device.

To do this, in the proposed device, the vibrating channel is mounted under the receiving bin and divided by a partition into two compartments having different volumes for coarse and exact weight. In addition, each compartment has a flap, one of which (for the release of coarse weight) is equipped with a roller for interacting with the stops, and the other is a pneumatic cylinder, the vibrating channel, pneumatic cylinder and the axis of the flaps are mounted on a bracket mounted m that can be rotated about the axis under the action of the pneumatic cylinder . Scales are equipped with sensors to control the work of pevmilindrov.

FIG. 1 shows schematically the proposed device, axonometrics; in fig. 2 and 3 - vibrating channel in the initial (horizontal) and inclined positions.

The described device contains a receiving hopper 1, a hoist for loading it, a vibrating channel 2, an automatic balance 3 mounted under it, mechanisms 4 and 5 located under it for packing boxes and their brands and a conveyor 6. The vibrating channel 2 is mounted below the receiving silo 1 and above the automatic balance 3 and is divided by a partition 7 into two compartments having different volumes for a coarse and precise weight.

The compartments have flaps 8 and 9 mounted with the possibility of rotation on the axis 10. On

the shutter 8 is fixed roller 11, which interacts with the lugs 12 and 13, which are mounted on the frame of the device. The valve 9 is provided with an earring 14 connected to the rod 15 of the pneumatic diaphragm 16. The vibrating channel 2 with the partition 7 with the flaps 8 and 9 and the axis 10 with the rollers 11 and the pneumatic cylinder 16 is mounted on a bracket 17 mounted on the axis 18 with the possibility of rotation relative to the latter. Axis 18 is fixed to the frame of the device.

The bracket 17 is connected to the pneumatic cylinder 19. Scales 3 are equipped with sensors (not shown in the drawing) to control the operation of pneumatic cylinders 16 and 19. Under the automatic scales 3 there is an intermediate vibratory channel 20, which is installed on the bracket 21 mounted on the axis 22 and can be rotated and the latter is attached to the frame of the device. By means of the lever 23, the brackets 21 are connected with the pneumatic cylinder 24. Mechanism 4

for packing boxes has a cassette 25 and

interacts with the conveyor 6 to move the boxes. The empty boxes are placed in container 26 and they are delivered from the bottom to the conveyor 6 by means of mechanism 27. An elevator for loading hardware contains a carpet 28, ropes 29, drums 30 and an actuator 31. One side of the receiving hopper 1 is illuminated on the cables 32, and the other rests on eccentric drive 33.

The device works as follows.

From the receiving bin 1, the parts fall into vibrating channel 2 in uniform portions, while roller 11 moves away from stop 12 and abuts against stop 13. As a result, flap 8 rotates on axis 10, freeing the passage of parts of vibrotray 2 from the wide compartment, and flap 9 this time is diverted by the pneumatic cylinder 16.

Thus, the hardware parts from the receiving bupker 1 through the wide and narrow compartments of the tilted vibrating channel 2 are poured into the hopper of automatic weights 3. With the accumulation in the last weight dose close to the nominal (coarse weight), the coarse weight sensor 3 acts on the pneumatic cylinder 19, which sets the grabber 17 in a horizontal position, while the roller 11 abuts against the stop 12, whereby the flap 8 blocks the output of the parts from the wide section of the vibrating channel 2. Next, the supply of parts It is only from the narrow compartment of the vibrating channel 2, which corresponds to the accumulation of parts in the hopper of the balance 3 for accurate weight.

Simultaneously, the parts arriving from the receiving bin 1 are accumulated in the vibrating channel 2 for a gross weight dose, which during the subsequent cycle is poured into the bunker of automatic weights 3. When accumulating in the last parts, the weight of which corresponds to the nominal one, the sensor of the exact weight of the scales 3 acts on the hydraulic cylinder 16, using through which the earring 14, the flap 9 rotates to the initial position and blocks the output of the parts from the narrow compartment of the vibrating channel 2. At the same time, the vibration of the vibrating channel 2 and the receiving hopper 1 is turned off and opens 3, bottom weights, resulting in OPVesova dose peresypaets intermediate zibrolotok 20. Then the bottom weights is closed and further forming cycle is repeated dely weight.

If there is a box on the position of the packaging mechanism 4, the pneumatic cylinder 24 is activated, which by the lever 23 rotates the bracket 21 on the axis 22, as a result of which the intermediate vibration flow 20 takes an inclined position and begins to vibrate. Details from the latter are poured into the box through the cassette 25 of the mechanism 4 packing boxes, after which the intermediate vibratory channel 20 returns to the initial (horizontal) position at which subsequent unloading is possible.

weights. The filled-in part, after lifting the cassette 25, pushes against the position of the mechanism 5 of the brand. At the same time, an empty box is pushed out of the container 26 to the conveyor 6, by which it

moves to the position of the packaging mechanism 4. Subsequently, the packaging cycle is repeated.
