Description

The utility model relates to measuring technology, mainly to devices for dispensing light spherical products, and can be used on packaging lines in the manufacture of such products or their sale.

A dosing device is known (patent RU No. 49985, IPC G01G 3/12, publication date 10.12.2005), containing a feeder-accumulator, a hopper, force-measuring sensors and a control unit. The storage feeder is located autonomously from the loading hopper. The latter is mounted on supports resting on racks with force-measuring sensors attached to them. Racks are rigidly fixed on the support platform. The loading hopper contains an outlet hatch with a valve that can be rotated by means of a pneumatic drive. The control unit is made in the form of a weighing electronic terminal with software and means of indication and control. The control unit is connected to the pneumatic actuator. In accordance with the programmed program and settings, the control unit issues control actions to the valve pneumatic actuator and controls the dosing process in the following modes:

registration of the initial mass of material in the hopper;

registration of the unloaded mass of material in the dosing process;

statistical calibration of the device according to control loads;

control of the mass of the empty loading hopper;

work in automatic mode.

The device is intended for measuring and dosing the weight of solids and bulk materials, in particular, for weighing and accounting for sugar beets that are supplied to processing plants in a continuous stream.

The disadvantage of the known device is the limited scope, due to the functionality of dosing materials with a relatively large mass, not prone to electrification as a result of friction and do not require special incentives to move from the hopper.

A device for dosing is known (patent RU No. 89508, IPC B65G 47/14, publication date 12/10/2009), containing a hopper connected to a vibrating tray, a cone-shaped bowl with an output tray, a conveyor, a sensor, a control unit and a storage device. Products from the loading hopper are fed into a cone-shaped bowl by means of a vibrating tray, where their flow is formed for subsequent piece feed to the conveyor. A sensor is fixed at the entrance to the conveyor, by means of which the appearance of the products is recorded and this information is transmitted to the control unit. The latter, in accordance with a given program, processes the information received, taking into account the shape and/or size of the products and issues control commands to the storage device, which, by means of pneumatic pushers, packs the products into appropriate containers. After they are filled, the control unit issues a command to stop the drives of the conveyor and the cone-shaped bowl. The device is designed for dosed sorting of spherical products during packaging.

The disadvantage of the known device is the limited scope due to:

the functionality of dosing spherical products with a relatively large mass, not prone to electrification as a result of friction in the hopper;

the implementation of dosing without prior registration of a given number of products and without fixing their number in the process of dosing.

The utility model is based on the task of expanding the arsenal of technical means for dosing spherical products due to a different implementation of the means for their supply and accounting, as well as a different relationship between these tools, which will allow dosing light spherical objects prone to electrification as a result of friction and requiring prompting to move from the feed hopper to the tray.

The technical result consists in the implementation of the task.

The problem is solved by the fact that the device for dispensing products of a spherical shape, containing a loading hopper, a tray, a control unit and a sensor, while the tray is fixed on the loading hopper, the latter is configured to feed products into the tray, and the sensor is connected to the control unit and is made with the possibility of fixing products during their movement and transmitting information to the control unit, according to the utility model, it contains a centrifugal dispenser with a drive and a means for finely dispersed moistening of products, and the control unit is connected to the drive of the centrifugal dispenser and the said means and is configured to enter information about the number of products for dosing, registering the number of products in the process of dosing according to the information coming from the sensor, storing and visual displaying the entered and recorded information and controlling the operation of the centrifugal batcher drive and the means for finely dispersed wetting of products in accordance with the entered quantity a set of products for dosing, while the centrifugal batcher is mounted in the hopper and is made in the form of a disk with cutouts, the transverse size of which corresponds to the size of the products.

In this case, it is expedient for the tray to be tubular in shape.

In this case, it is also expedient for the sensor to be attached to the tray and to be made in the form of a non-contact optical sensor.

In this case, it is also expedient for the control unit to comprise a microcontroller and an indication panel and a control panel connected to it.

In this case, it is also expedient that the drive of the centrifugal batcher be fixed under the bottom of the feed hopper and connected to the disk by means of a shaft.

In this case, it is also advisable that the means for finely dispersed wetting of the balls contains a nozzle and a hydraulic pump connected to it, while the nozzle is fixed on the loading hopper, and the hydraulic pump is made with the possibility of connection with the control unit.

The claimed design of the device for dispensing products of spherical shape ensures the achievement of the mentioned technical result. In particular, the use of a centrifugal feeder with a drive in the device, its placement in the loading hopper and making it in the form of a disk with cutouts, the transverse size of which corresponds to the size of the products, allows for forced piecewise movement of products from the loading hopper to the tray. The use in the device of a means for finely dispersed moistening of products makes it possible to exclude the "sticking" of products in the hopper as a result of their electrification. The connection of the control unit with the drive of the centrifugal batcher and the mentioned means and its implementation with the possibility of controlling their operation in accordance with the entered information about the number of products for dosing allows you to automate the operation of the device for a different number of products in a batch. And the implementation of the control unit with the possibility of entering information about the number of products for dosing, registering the number of products in the process of dosing according to information coming from the sensor, saving and visually displaying the entered and recorded information also allows you to automate the dosing process and improve the usability of the device.

The essence of the claimed utility model is illustrated by examples of the implementation of the device developed by the Limited Liability Company "ELVEY" (Moscow).

The figures of the drawing show: in Fig. 1 - appearance of the device; in fig. 2 - view A in Fig. one; in fig. 3 is a block diagram of the functional elements of the device.

The device for automatic dosing of light spherical products contains a loading hopper 1, a tray 2, a centrifugal dispenser made in the form of a disk 3 with a drive 4, a control unit 5, a sensor 6 and a means for fine moistening of the balls, consisting of a nozzle 7 and a hydraulic pump 8, connected to the tank 9 for storing liquid. The nozzle 7 is fixed on the loading hopper 1 by means of a rod 10. In the considered embodiment, the loading hopper 1 is fixed on the support frame 11.

The hopper 1 consists of the upper 12 and lower 13 shells of different diameters, connected by means of a transition element 14 in the form of a truncated cone. Tray 2 is made tubular and fixed on the lower shell 13 coaxially with the opening 15 for feeding products. The disc 3 of the centrifugal dispenser is mounted in the lower shell 13 above the hole 15 and is made with cutouts 16. The dimensions of the hole 15 and cutouts 16 correspond to the diameter of the products. The drive 4 is fixed under the bottom of the hopper 1 and is connected to the disc through a shaft (not marked).

The sensor 6 is made in the form of a non-contact optical sensor and is fixed on the tray 2 with the possibility of fixing the movement of products inside the tray 2.

The control unit 5 is fixed on the lower shell 13 and consists of a microcontroller 17 and an indication panel 18 and a control panel 19 connected to it. The microcontroller 17 is also connected to the sensor 6 and through the power supply 20 to the drive 4 and the pump 8 (Fig. 3). The microcontroller 17 contains a program that can enter the number of products for dosing, register their number in the process of dosing according to the information coming from the sensor 6, store the entered and recorded information, visually display it on the display panel 18 and control the operation of the drive 4 in automatic mode and pump 8 in accordance with the entered quantity of products for dosing. In the semi-automatic mode of operation, the drive 4 can be turned on by means of the pedal 21 connected to the power supply 20.

Diluted glycerin or pure water is used as a moisturizing liquid.

The device is used as follows.

Example 1. Using the device in automatic mode.

Products, such as light plastic balls for a dry pool, fall asleep in the hopper 1. Using the control panel 19 in the memory of the microcontroller 17 enter the number of balls for dosing. The microcontroller 17 through the power supply 20 issues a command to turn on the drive 4, which drives the disk 3, and turn on the pump 8, which sprays a finely dispersed moisturizing liquid over the balls through the nozzle 7, as a result of which the force of attraction between them decreases due to the redistribution of charges on the surface . When disk 3 rotates, the balls fall into cutouts 16 and, under the action of centrifugal force through hole 15, are alternately fed into tray 2. Sensor 6 records the movement of balls inside tray 2 and transmits this information to microcontroller 17. The latter, in accordance with the program, registers the number of balls that have passed through tray 2, and upon reaching the specified number, it automatically sends a command to turn off the drive 4 and pump 8. During the operation of the device, the microcontroller 17 transmits to the display panel 18 information about the specified number of balls and their current number, recorded by sensor 6 in tray 2. From Tray 2, the balls enter a package for later storage or transportation (not shown).

Example 2. Using the device in semi-automatic mode.

Filling the balls into the loading device 1 and introducing their quantity for dosing in the microcontroller 17 is performed similarly to example 1. Further, the operator, using the pedal 21, through the power supply 20, turns on the drive 4 and the pump 8. Subsequent fixation of the balls by the sensor 6, their registration in the microcontroller 17 and reflection on indication panels 18 are carried out in automatic mode similar to example 1. The operator monitors the information on the indication panel 18 and when the number of balls specified by the program is reached by means of the pedal 21, through the power supply 20, turns off the drive 4 and the pump 8.

The inventive dosing device has been tested in real operating conditions and confirmed the technical result. The device is characterized by a relatively simple design, high reliability and ease of use, which allows it to be used on packaging lines both in the manufacture and in the wholesale or retail sale of light spherical products.
