Abstract

PURPOSE:To continuously and efficiently charge liquid or high viscous slurry into vessels even when the volume of the vessels are different and the transferred intervals are at random, by providing a vessel transfer conveyor, a constant rate feeder of liquid or high viscous slurry, a deciding means of the capacity for the vessels, and a control circuit. CONSTITUTION:The servo-motor 5 of a transfer conveyor for the vessels stops to discontinue a vessel transfer conveyor 4 upon detecting of a conveyor original position detector 7. And the servo-motor 2 driving a constant rate charging pump is put on and then a constant rate charging pump 3 is driven by interlocking therewith to charge automatically the contents in the charging materials hopper 1 into the vessel 6 of A1 with a constant volume and rate. The charged volume is read by the bar code reader 12 and memoried in a control circuit to be accurately charged by the figure. When an encoder equipped inside the servo-motor 2 counters a preset puls number, the servo-motor 5 of the transfer conveyor for the vessels starts to drive the vessel transfer conveyor 4 to transfer the vessel 6 of A2 by as far as the distance D1 memoried by the control circuit 10 to the charging position right under the constant rate charging pump 3. By this repetition, the fed vessels are efficiently and continuously treated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for filling a liquid or a high viscosity slurry into a large number of containers that are continuously fed by a conveyor. It is particularly useful as a device for filling containers of different capacities while feeding them randomly.

(Prior art) As an apparatus for filling a container with this type of liquid or high viscosity slurry, the container is placed below the supply port of the apparatus for supplying the liquid or high viscosity slurry, and then the liquid/slurry is filled into the container. While filling, while observing this, the supply device was stopped when a predetermined amount was reached, and the next empty container was filled.

(Problems to be Solved by the Invention) With this conventional device, it was not possible to continuously fill the containers, and the device was not unmanned. In particular, it is difficult to carry out the process continuously and unattended, especially when the capacity of the containers changes or when the containers are fed at uneven intervals. An object of the present invention is to provide an apparatus that can efficiently fill containers continuously and unmanned even if the containers have irregular capacities and are sent at random intervals.

(Means for Solving the Problem) The gist of the present invention that solves the problem is to provide a container transfer conveyor that sequentially transfers containers containing a liquid/high viscosity slurry, and a filling position set in the middle of the container transfer conveyor. A quantitative supply device for liquid/high viscosity slurry provided above, and a capacity determining means for determining the capacity of the container that has arrived at the filling position of the container transfer conveyor by a detection device or a storage circuit in which the capacity is stored in advance. When the empty container is sent to the filling position, the container transfer conveyor is stopped, and then liquid/high viscosity slurry is supplied from the metering supply device by the volume of the container given by the capacity determining means, and the filling is completed. The continuous filling device for liquid/high viscosity slurry is characterized in that it is equipped with a control circuit that starts the post-container transfer conveyor and operates it until the next empty container comes to the filling position.

(Function) In this invention, containers with a capacity of type 4 are sent by a container transfer conveyor with random intervals. The capacity of the container is directly measured by detecting the dimensions of the container or a label mark on the container indicating the volume with a detection device. Alternatively, the capacity is determined by comparing the container type label/mark attached to the container with the storage circuit. Alternatively, the capacity information is determined by recalling the capacity information from a memory circuit in which the corresponding capacity of the containers in that order is input and stored in advance based on the order of the containers.

When the container reaches the filling position of the container transfer conveyor, the control circuit causes the container transfer conveyor to stop. Whether or not the container has arrived at the filling position may be determined by a container detection sensor located at the filling position, or by measuring the arrangement interval of containers in advance and feeding the containers by that distance, the container is automatically moved to the filling position. You may also move it up to

Next, when the container is stopped at the filling position, the metering supply device is activated by the control circuit to supply a fixed amount of liquid/high viscosity slurry, and the supply stops when the capacity of the container, which has already been obtained from the capacity information, has been supplied. Then, the container transfer conveyor is driven to move the next empty container to the filling position. By repeating this process, containers sent in sequence can be efficiently and continuously processed.

(Example) Examples will be described below based on the drawings.

In this embodiment, a deletion encoder is attached to the servo motor that drives the container transfer conveyor, and the control circuit controls the servo motor in accordance with a signal indicating the number of pulses generated from this encoder. The supply device includes a hopper for liquid, high viscosity slurry, etc., a servo motor for a quantitative filling pump equipped with an encoder, and a quantitative filling pump for supplying a fixed amount. The capacity determination means employs a barcode reader that is installed upstream of the container transfer conveyor and reads a capacity display bar hood attached to the center of the sidewall of the container, and the barcode on the sidewall of the container is determined. In addition, the interval between containers flowing on the container transfer conveyor (
The distance) is calculated from the difference in the encoder values of the servo motor for driving the container transfer conveyor, and is stored in the control circuit, and the containers are filled sequentially by sending the container transfer conveyor from the filling position to the next container by the memorized interval. This is to stop it at a certain position.

(Assume that the items are placed on a conveyor by continuous automatic transfer.) The device (activation) activates the container transfer conveyor (4) and moves the container (6) as shown by the arrow. At the same time, the barcode reader (1, 1) reads the barcode (lυ) of the container (6), calculates the capacity of the container (6) and the distance between the containers (6), and stores them in the control circuit (II). The position detected by the conveyor origin position detector (7) is the origin of this device (
At this time, set the A1 container (6) so that it is located directly below the quantitative filling pump (3)). Conveyor origin position detector (7
) is detected, the container transfer conveyor servo motor (5
) stops and the container transfer conveyor (4) stops. At the same time, the servo motor (2) for driving the metered filling pump is started, and the connected metered filling pump (3) is interlocked, and the filling in the filling hopper +11 is automatically fed at a fixed rate and at a constant speed into the container A ( 6) Filled inside. The volume to be filled is first read by a bar code reader (Ll) and stored in the control circuit, and that volume is filled.This quantitative performance is accurately performed by controlling the rotation speed of the quantitative filling pump (3).

As for constant speed, by inputting a desired filling speed into the control circuit (6), the metered filling pump servo starter (2) rotates at a constant speed. This allows constant speed filling.

When the encoder built into the metered filling pump servo motor (2) reaches the set number of pulses, the container transfer conveyor drive servo motor (5) starts and the container transfer conveyor (

By matching this with the required number of pulses (the number of pulses corresponding to the interval D1 drive), it moves and stops exactly one pulse.

Similarly, for constant speed, when the desired speed is set in the control circuit (11), the servo motor (5) for driving the container transfer conveyor (5) makes one constant rotation.As a result, the container transfer conveyor (4) rotates at a constant speed with the interval D□ drive.

After the encoder of the servo motor (5) for driving the container transfer conveyor consumes the required number of pulses (distance D1 drive), the container transfer conveyor (4) stops, and the servo motor (2) for driving the quantitative filling pump starts and is connected. Metered filling pump (

) is automatically filled at a constant fixed rate.

The capacity to be filled into the A2 container (6) is read by the par food reader (1) and stored in the control circuit (11), and only this capacity is filled.

The filling amount and filling speed are controlled by the required number of pulses and rotational speed corresponding to the A2 container (6), as described above, and fixed-quantity filling is performed.

When the encoder built into the servo motor (2) for driving the quantitative filling pump consumes the set number of pulses (container A2 (
6), the required filling is completed), the servo motor (5) for driving the container transfer conveyor starts, interlocks the container transfer conveyor (4), and moves the A3 container (6) at a constant speed by the interval D2 stored in the control circuit Tll.
