Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for feeding chemicals in a chemical liquid adjustment step in a chemical process. In particular, the present invention relates to an apparatus for automatically feeding a granular material.

[Related Art] In a chemical process, a reaction is performed using a large number of chemicals and chemical solutions. For example, in suspension polymerization and emulsion polymerization in a polymer production process, a large number of chemicals such as monomers, emulsifiers, dispersants, activators, catalysts, terminators, and molecular weight regulators are used. Moreover, these chemicals are rarely used alone, and can be dissolved in solvents,
It is used after being suspended or emulsified in water or a solvent together with a dispersant, an emulsifier, or the like.

Adjustment of these chemicals is one of the important operations in such a chemical process, and since it requires accuracy and time, adjustment of the chemicals is an important step.

For this reason, a manual batch system is used for adjusting these chemical solutions. In this case, an operation of introducing a chemical for adjusting the chemical solution into the adjustment tank is involved. However, this operation has problems in working environment and operation such as generation of odor, toxicity and dust of the chemical.

As one of the measures to reduce such operational difficulties, a method has been adopted in which a hopper scale or the like is installed to measure and charge the medicine. However, even in this case, as the number of types of chemicals increases, more hoppers are required, which causes difficulty in equipment. Also,
Work difficulties associated with the introduction of chemicals into the hopper cannot be eliminated.

From such a background, there has been a demand for an automatic dispensing apparatus capable of accurately and automatically dispensing a medicine by arbitrarily combining various kinds of medicines.

[Problems to be Solved by the Invention] The present invention aims to eliminate problems in operation and process in such a chemical solution adjusting operation, and relates to a chemical solution adjusting system described below. That is, 1) a fork device for taking out the container from the container storage space 2) a hand that can hold and rotate the container and an extendable arm device 3) a traveling and elevating device for moving between the container storage space and the adjustment tank, etc. It is an object of the present invention to eliminate a difficulty in operation associated with an operation of charging a chemical for adjustment of a chemical solution into an adjustment tank, which has conventionally been performed manually by an adjustment system.

[Means for Solving the Problems] The drug dosing device of the present invention has the following functions. That is, 1) a fork capable of taking a container containing a chemical in and out of a container storage space, and having a motor, an air cylinder, or the like as a driving source, and transmitting power by a belt or a gear. Apparatus 2) An apparatus having a hand capable of holding a medicine container and rotatable while holding the container. For example, the hand is pressed against the container with an air cylinder to grasp the container, or the hand is hung on the jaw of the container. 3) Gripping device that has a telescopic arm that can lift and move the container from a fork while holding the container, and that can expand and contract the arm with an air cylinder or motor and determine its position. 4) Adjustment tank and chemicals Elevating and moving devices that can be moved to container storage areas, such as motors, belts, rails, linear guides, ball screws, 5) A moving device consisting of a gear, etc. 5) A device that taps the container while rotating the container to improve the discharge of chemicals. For example, a hammer made of wood, metal, or resin is operated by an air cylinder, or Discharge device vibrated by vibrator 6) As an accessory device of the above device, a device having a multi-stage container storage space capable of storing medicine containers in a three-dimensional manner. It has a hopper, and has a function that allows the hopper to be selected depending on the properties of the chemical, for example,
A device that can move and switch the hopper on the adjustment tank when chemical contamination is not allowed.

8) A chemical solution adjusting system is constituted by those devices and systems that can be operated by a sequencer or a computer.

[Action] The thus-configured medicine dosing device takes out the medicine container from the storage location of the container using a fork,
After grasping with the hand, move up and down, run and move to the front of the adjustment tank,
Next, the arm is extended and the container is moved to the upper part of the input hopper of the adjustment tank. Thereafter, the container is turned over and the chemical is put into the adjustment tank. After loading, the container is rotated to the original position, the arm is contracted, and then the container is conveyed to the original container storage place by ascending and descending and running.

By performing this series of operations for each container containing a pre-measured medicine and for each adjustment tank selected in advance, the medicine introduction work is automated and the chemical liquid adjustment system is implemented.

Further, according to the present invention, a conventional hopper scale can be arranged in this apparatus, and automatic weighing can be performed in combination with the above-mentioned robot.

Hereinafter, the present invention will be described in more detail with reference to Examples, which illustrate embodiments of the present invention and do not limit the present invention.

Embodiment FIGS. 1 and 2 show a chemical solution adjusting system according to an embodiment of the present invention.

In FIGS. 1 and 2, reference numeral 1 denotes a chemical solution adjusting robot main body, reference numeral 2 denotes a storage space for a three-dimensional container, reference numeral 3 denotes a movable container, and reference numeral 4 denotes a hopper for charging a dissolution tank.

The robot 1 moves in front of the container storage 2 and inserts a fork 10 below the container, lifts the container, and removes the container 3 from the container storage. The robot grasps the container on the fork with the hand of 11 and moves in front of the hopper of 4 in that state. After that, raise the 15th arm, lift the container from the fork, extend the arm, and move the container onto the hopper. The container is inverted by rotating the eleventh hand, and the medicine is put into the hopper.

After the container is put into the container, the hand and the arm are returned to their original positions, the robot is further moved, and the container is moved to the weighing table 6. After confirming the empty space, the container is stored in the container place using a fork. At this time, if the container is not empty, it is moved again onto the hopper and is reloaded. By repeating this operation, the designated fixed container is moved to the designated hopper and the contents are charged. The fork is moved in and out using 13 cylinders. The fork is moved up and down by 9 elevating motors. Arm expansion and contraction is 14
The arm is raised and lowered with 12 cylinders.

The container gripping hand is pushed inward by a cylinder and grips the container. The rotation of the hand is driven by eight motors.

The running of the robot is performed by the running motor of 7,
Run on rail # 5. The robot is moved up and down by 9 elevating motors, and is moved up and down in combination with a ball screw.
