Reference numeral 1 denotes a storage bin unit, wherein the storage bin unit 1 has a plurality of storage bins 11 arranged in a circular shape on the structure body 2 having a circular shape, and the storage bins 11 are different from each other. They are arranged at regular intervals with different phase differences on two concentric circles of radius.

A triangular hopper 12 is attached to the lower portion of each storage bin 11 constituting the storage bin unit 1, and these hoppers alternately vary their installation heights. That is, the hoppers of the storage bins arranged on concentric circles of small radius are installed at high positions, while the hoppers of the storage bins arranged on concentric circles of large radius are installed at low positions, and the hoppers 11 are Each is connected to supply the medicine to the transfer cylinder 31 of the screw feeder (3).

The shape of the hopper 12 attached to the lower portion of the plurality of storage bins 11 is formed in a triangular shape, so that the cross-sectional area of the upper portion is narrow and the cross-sectional area of the lower portion is wide, thereby loading the load of the chemical stored in the storage bin 11. Dispersion was made to prevent intensive action on the screw 32 of the screw feeder 3.

Each of the plurality of screw feeders 3 connected to the hopper 11 extends long so as to communicate with the centrally located collection container 4 so that the chemicals transported by the screw 32 can be discharged to the collection container 4. Consists of.

On one side (outer side) of the transfer cylinder 31 of each of the screw feeders 3, a power unit is installed using the geared motor 33 as a power source, and the discharge port of the transfer cylinder 31 is provided on the other side (center side). A discharge control device having a pneumatic cylinder 35 for operating the gate 34 to open and close is installed.

The discharge control device is a solenoid valve 36 for turning on / off the pneumatic and a regulator (37) for adjusting the pneumatic pressure to a constant pressure (low pressure in the present invention) controls the operation of the pneumatic cylinder (35) piston ( 35a) has a low speed operation, so the gate 34 attached to the end of the piston (35a) is configured to open and close the outlet at low speed.

In addition, the screw feeder (3) is connected to the hopper 11 having a different installation height, so that the plurality of screw feeders (3) arranged in a circular installation height is also installed alternately up and down, such up, down The alternating installation configuration enables the installation of a discharge control device which is installed close to the collecting container 4 side even if a plurality of screw feeders 3 are installed with a narrow angle of phase difference, as well as the piston of the pneumatic cylinder 35 ( 35a) and the gate 34 attached to the piston is to secure a space for opening and closing operation.

Next, the collection container 4 is installed in the center structure 40 fixed to the center of the structure body 2, the inside of each outlet and gate 34 of the screw feeder (3) is drawn in Since the chemicals transferred from the screw feeder 3 are completely discharged to the water collecting container 4 and are contained in the weighing container 41, the weight of the chemicals contained in the weighing container 41 as the load cell is installed as usual. Will be weighed.

The metering container 41 progressively measures the chemicals sequentially discharged sequentially from the outlet of the transfer cylinder 31 of the screw feeder 3 which is connected to the water collecting container 4, and thus the individual supply amount of each chemical and the entire chemicals. To measure the supply of

And the lower portion of the measuring container 41 is installed in two stages of the discharge vessel (5a) (5b) is provided with a flap valve that is opened and folded like a butterfly wing, the canvas between the two discharge vessel (CANVAS: 51) is installed.

The discharge container 5a at the upper end of the discharge container installed in two stages as described above allows the medicine to be injected into the metering container 41 to be stored, enabling the metering.After the metering is completed, the valve valve is opened. After discharging to the discharge container (5b) at the bottom and closing again, the flap valve of the discharge container (5b) at the bottom receives the chemical discharged from the top in the closed operation state and then opens the operation. The discharge of the chemical to the transfer line, if the transfer line for transferring the chemical in the vessel (VESSEL) to transfer the drug using high pressure air, the high pressure air affects the discharge tank (5b) at the bottom, at this time The impact of the high pressure air acting on the discharge tank 5b at the bottom is removed by the buffering action of the canvas 51 and thus is not transmitted to the discharge container 5a at the top. You can protect deusel.

Next, a chemical injection hopper 6 for introducing a chemical into each storage bin 11 is installed at an upper portion of the storage bin unit 1, and the chemical injection hopper 6 is a storage bin unit 1. A pair of rotation guides 63 formed on two bars (BAR) are attached to the rotating body 62 installed on the top of the fixed shaft 61 installed in the center of the horizontal state, and the rotation guide 63 Supported by the circular rail plate 64 is attached to the wheel 65 that can be rotated is configured to rotate the rotation guide 63 itself with the rotating body (62).

The inner surface of the rotary guide 63 is provided with a guide rail 66 to enable the sliding movement while supporting the chemical injection hopper (6).

That is, by inserting two rollers 67 mounted on each side wall of the chemical injection hopper 6 into the guide rail 66, the chemical injection hopper 6 is installed in a stable state and at the same time the center It is possible to move forward and backward.

The vibration of the injection guide container 68 is prevented from being transmitted to the medicine injection hopper 6 through the canvas 69 between the medicine injection hopper 6 and the injection guide container 68 installed at the lower portion thereof.

A vibrator 681 is attached to one side of the input guide container 68, and the outside of the input port of the input guide container 68 is operated by a manual lever 682 to block the upper portion of the storage bin 11. The sealing plate 683 is provided. The manual lever 682 and the sealing plate 683 are connected by a connecting link 684, and the connecting link guides the lifting operation up and down by a pin shaft penetrating the long hole of the fixed section 685.

Next, the upper portion of the chemical injection hopper (6) is equipped with a bag filter (7) to collect the dust generated during chemical injection to prevent the dust of the chemical to be scattered to the outside, which is a toxic chemical harmful to the human body Even if it is not to scatter to the outside to ensure a safe working environment, and also to the outside upper end of the bag filter (7) using the air pressure to shake off the dust dust collected in the bag filter (7) An air tank (71) and a fan (72) for exhausting air were placed.

The number of the storage bins 11 constituting the storage bin unit 1 in the control box 8 on the top of the rotating body 62 to enable the rotation operation of the chemical injection hopper (6) and The same number of sensors were installed. The control box (8) is an operation of the apparatus required for injecting the drug when the chemical injection hopper (6) coincides with the storage bin into which the chemical is injected, for example, the vibrator (681) and the fan (72), etc. It is configured to operate.

It will be described the operation of the present invention in this way.

First, explaining the action of injecting the chemicals into the storage bins 11 constituting the storage bin unit 1, the operator manually rotates the rotary guide 63 to the desired storage bin 11 of the chemicals In the case of the storage bin located on the inner concentric circle, if the storage bin in which the chemical injection is set is located at the outer concentric circle, the chemical injection hopper 6 is slid outward. It is to slide the input hopper 6 inward.

The sliding movement of the chemical injection hopper 6 as described above is possible because the roller 67 inserted into the guide rail 66 inside the rotation guide 63 performs the rolling operation, and also the chemical injection hopper 6 When the chemical injection hopper 6 is matched with the set storage bin 11 by sliding operation, the sensor of the control box 8 connected to the storage bin receives a signal and informs the operator that the match is made. When the operator presses the manual lever 682, the sealing plate 683 is lowered to block the periphery of the inlet of the feeding guide container 68. The upper end of the storage bin 11 is sealed by the sealing plate 683. This prevents dust from scattering to the outside during chemical injection. That is, since the lower end of the input guide container 68 is installed in a state slightly separated from the upper end of the storage bin 11, the upper end of the storage bin 11 is caused to generate a gap, so that dust is introduced through the gap during chemical injection. Since it can be scattered to the outside, it is prevented by a sealing plate.

By the manual operation of the operator as described above to store the various types of drugs in each storage bin 11 of the storage bin unit 1 individually, and then select and supply a predetermined amount of drugs stored in each storage bin 11 In the above, the embodiment of the rotation and advancing movement operation of the chemical injection hopper (6) has been made to manual, but can also be automatically operated by installing an automated equipment.

As described above, the operation process of supplying quantitatively stored chemicals to each storage bin 11 constituting the storage bin unit 1 by type is performed by a screw feeder 3 connected to the hopper 12 of each storage bin 11. The screw feeder 3 is discharged by a predetermined amount while operating one by one in a selected order.

That is, when the geared motor 33 of the screw feeder 3 is driven as shown in the example of FIG. 6, the screw 32 rotates to transfer and discharge the chemicals in the hopper 12 having a triangular shape. The hopper 12 is formed in a triangular shape to disperse the load of the chemicals stored in the storage bin 11, thereby preventing the concentrated load from acting on the screw 32 and preventing the coagulation of the chemicals at the same time. 32) while smoothly rotating operation can be expected to prevent the operation of the overload on the geared motor 33, and also to improve the transport efficiency of the drug by a narrow and wide arrangement of the wing pitch of the screw (32). In other words, the narrow and wide wing pitch of the screw 32 is configured to transfer a small amount of the chemical to the narrow pitch at the narrower pitch, so that a space for receiving the chemical at the wide pitch portion of the small amount of the chemical is handed over. It is formed to be able to receive the drug in a portion outside the narrow pitch is transported in the event that the drug in the hopper 12 is transferred in the same amount as a whole, accordingly the storage surface of the drug stored in the storage bin (11) It is reduced while forming a horizontal plane.

On the other hand, the piston (35a) of the pneumatic cylinder (35) installed on the discharge cylinder 31 discharge port side of the screw feeder (3) for transferring the chemicals is released to open the gate 34 to transfer to the screw (32) The drug to be discharged to the water collecting container 4 as an outlet, the drug discharged into the water collecting container 4 is measured while being directly stored in the metering container 41, the drug container 41 is discharged When the amount reaches a predetermined amount, the signal is sent to a control device (not shown), and the control device stops the geared motor 33 and simultaneously immerses the piston 35a of the pneumatic cylinder 35. The gate 34 blocks the outlet. As a result, the weighed drug is no longer discharged.

Subsequently, the chemicals stored in the next storage bin 11 are sequentially supplied to the metering container 41 by the sequential operation of the screw feeder 3, and the chemical supply operation at this time is performed as described above. By the operation of the set amount of the drug is discharged to the collecting container (4) is supplied to the metering container 41, the metering container (41) is the metered by progressively supplying the next drug supplied with the previously completed drug When the progressive weighing is completed, the medicine is supplied from the next storage bin and the operation of repeating the progressive weighing is repeated to determine a predetermined amount of various types of chemicals stored in each storage bin 11 of the storage bin unit 1. In the state where the various types of chemical weighing are completely completed, the flap valve of the upper discharge container 5a is opened to discharge the chemicals into the lower discharge container 5b.

The discharge container 5b at the lower side of the medicine weighed as described above is discharged to a chemical storage tank by discharging the medicine to a vessel (not shown) or a conveyor installed at a lower side thereof, and transporting the medicine by using high pressure air. In the case of the vessel, the air pressure affects the discharge vessel 5b at the lower side when the chemical is transferred to the high pressure air, wherein the canvas 51 installed between the upper and lower discharge vessels 5a and 5b is By damaging the air pressure acting on the discharge vessel 5b at the bottom to block delivery to the discharge vessel 5a at the top, the precision weighing parts such as load cells installed in the weighing vessel 41 are damaged or damaged. It is possible to prevent the chemicals supplied from the storage bin unit 1 to continue to precisely weigh.

According to the present invention as described above, the storage bin unit is arranged in a circular shape, the phase difference is arranged on two concentric circles with different radii to reduce the installation area of the storage bin unit holding a large number of storage bins In addition, since the hopper positions of the storage bins installed in different phases at different radii are alternately installed at different heights, the screw feeder can be installed even when a large number of storage bins are installed. The opening and closing operation of the gate for opening and closing the outlet of the drug is effective to be made smoothly, in particular, the present invention is installed in the center of the storage bin unit arranged in a circular measuring container in the center of the medicine supplied from each storage bin Accurately accumulate and measure each medicine sequentially ordered by supplying and weighing Not only does it have the effect of dispensing, but it also has the effect of simplifying the delivery line of chemicals by discharging various types of chemicals that have been weighed together in one place, and also making the storage bin unit circular. By installing the chemical injection hopper around the fixed shaft, it is necessary to mix several kinds of chemicals in small amounts such as the effect of making it easy to inject the chemicals into each storage bin by rotating and sliding forward and backward operation. It is the invention of a precision weighing system that can be usefully used by livestock feed producers or pharmaceutical producers.
