Description

one

The invention relates to a packaging technique, and may be used in baking industry for dosing piece goods. for example prnikikov. . .

It is known that a device for dosing piece meal, containing a transducer, comprising an area of 5 guides, | kg an item counting mechanism, made in the form of a conveyor with guides / expander and a weighing mechanism fl

The disadvantage of this device is the inaccuracy of the dosing account. items. KpoMfe, in this device, it is necessary to strictly orientate the objects, for example, the tracks to be dispensed. The presence of the orienting device, as well as the mechanism of the reciprocating rejection of the dumper, significantly complicates the design of the device. The frequency of operation of this device limits the increase in performance.

The purpose of the invention is to improve dosing accuracy and increase productivity.

This goal is achieved by the fact that the device is equipped with an additive mechanism containing a drive brush, kneaded over the extreme range of the pre-operator and installed with the possibility of swing and a bunker, with grippers fixed on the conveyor belt of Lukhanizm object counting and made in the form of elastic W-shaped plastic.

Tin, at the same time at the base of the platform of the converter of rows there are cuts for the passage of the grippers, besides the brush has an electromagnetic drive., -:

Claims (2)

The device for metering contains a flow control mechanism, including a pad 1, a spring 2 and a sensor 3, a conveyor 4 with rods 5, a converter-row, made in the form of an inclined pad 6 with guides 7. In the inclined pad 6, slots 8 are made. The piece counting mechanism comprises a conveyor 9 with guides 10, the conveyor 9 being equipped with towers 11, embedded both on the slats 2 of the conveyor 9 and chutes. The additive mechanism includes a brush 14 controlled by an electromagnetic drive 15, and a hopper 16 with a bottom underneath 17. Contro a flax weighing mechanism from weights 18, a bunker 19, the bottom of which 20 opens and closes from the cam 21, through a system of levers 22, a weight pad 23, controlled from a cam 24 through a system of levers 25. The device works as follows. Objects to be dispensed, for example, pics, with continuous flow to the swinging platform 1. The platform 1 is adjusted to a certain load (mass) by means of the spring 2. In the event of an overload, pad 1 lowers / triggers sensor 3 and receives a somand to switch off the flow supplying the device. The switching mechanism depends on local conditions and is not included in the system of the device for dosing the plugs. Then, the plugs with the help of rods 5, mounted on the chain conveyor 4, are moved to the rows converter. In the converter of rows of rows, on an inclined platform 6, under their own weight, roll onto guide rails 7 and fill them, forming rows. At the base of the platform in the cage row, three slots 8 are made for the passage of the grippers 11. Above the rim, a transducer is mounted on the brush 14, which is rocking from an electromagnet. With a free (non-switched) electric magnet, the brush 14 holds the weight of a number of blocks, preventing them from rolling down to the slots 8. With the command on the electromagnet, the brush 14 is raised from,. frees the rules and the whole, the row moves to the slots 8. The grippers 11, fixed on the slats 12 of the conveyor 9, pass through the slits 8, capture the lying prints, and regardless of how the spindle lies up or down, remove them from the platform 6 and transported to the control-weighing mechanism. The grippers 11 are made in the form of elastic W-shaped plates inserted into the strips 12 fixed on the conveyor 9. Depending on the number of grips 11 fixed on the conveyor 9 of the counting mechanism, the required number of dose for dose, including even or odd. Through the diverting guide 13, the counted number of ribs enters the hopper 19 with weight 18. To eliminate the oscillation of the arrow of the balance 18 when dropping the ribs, before dumping the arm 23 is clamped from the cam 24 through a system of levers 25 .. How TQJibKO. 19, dose is weighed. A photo device 26 is mounted in the scale 18. If the dose mass is within the normal range, the scale arrow is outside the photo device 26. If the dose mass is less than the norm, the scale arrow is within the photo device 26, the command enters the additive electromagnet, bottom 17 of the hopper 16 opens and the strand located there enters the hopper 19 of the balance. At the same time, a command is received to the brush 14. Brush 14 releases a number of plugs, and they move to the slits, and at this time, the gripper 11 removes one pin and drops it into the hopper 16 of the additive mechanism. The brush 14 returns to its original position. A weighted dose from the hopper 19 of the scale 18 goes to the package, while the bottom 20 of the bunker 19 opens from the cam 21 through a system of levers 22. The proposed device has high performance by ensuring the counting of piece items during continuous movement of the conveyor 9. The grippers 11 pick up the straps any position that does not require an orientation of its device. Claims of the Invention D. A device for dispensing piece objects, for example, riders, containing a series converter, including a platform with guides, a mechanism for counting objects, made in the form of a conveyor with guides and a control-weighing mechanism that differs from for the purpose of higher-. nor is the accuracy of dosing and productivity increase, it is marked by an additive mechanism containing a drive brush placed above the extreme range of the converter and installed with swings, and a bunker with grippers fixed on the conveyor of the counting mechanism of objects and made in the form of elastic W-shaped plates at the same time, at the base of the platform, the rippers are made for passage of the grippers. 2. The device according to claim 1, characterized in that the brush has an electromagnetic drive. Sources of information taken into account in the examination of 1 ..
