Description

Checkweigher integrated counter { counting machine integrated with loadcell }

The present invention relates to an integrated counter for each checkweigher, and more particularly, a cylindrical counting unit having an inlet opening for accommodating the product on the outer circumferential surface so that the product of a predetermined quantity is packaged more accurately and quickly, and a product having a very small weight. It relates to an integrated counter for each weight line equipped with a load cell unit that electronically checks the weight so that it can be precisely measured through the electronic weight check.

In general, there are many types of drugs manufactured by pharmaceutical companies, and depending on the dosage form of the drug, it can be divided into liquids, granules, capsules, or pills.

Among these drugs, capsules or pills (hereinafter referred to as pills) are packed in a certain number of pill bottles and packaged, and such pill packaging is configured such that a large amount of pills put into the hopper form a number of rows along the inclined plate provided at the bottom of the hopper. Hereinafter, various prior art related to pill packaging will be described.

First of all, Korean Patent Laid-Open No. 10-2002-0014127 (2002225) discloses a "quantitative tablet supply device".

This is because a large amount of pills put into the hopper can be withdrawn as much as the number set by the operator, so small-volume packaging is possible, the counting of pills is accurate, and no vibration is required to move the pills, so there is no dust due to noise and vibration. It also relates to a 'quantitative tablet supply device' that is simple and easy to maintain.

In addition, Korean Utility Model Registration No. 20-0341492 (2004131) discloses a "medication guide for tablet counting packaging device".

This relates to a drug introduction guide applied to a counting packaging device for counting tablet-type pills and putting them into a pill bottle that is moved on a rail on a table, and more specifically, the medication introduction guide that comes into contact with the pill as it descends. The slanted inner part is configured in a polygonal shape to prevent rotation by centrifugal force, and the lower part from which the pill exits is configured in a circular shape to induce the pill to be discharged smoothly, thereby preventing the bottleneck at the outlet side where the passage is drastically reduced. It is designed to improve productivity and increase productivity.

As such, although various prior arts have been proposed in relation to pill packaging, it has a disadvantage in that it does not solve the fundamental problem of lowering work efficiency due to a large amount of time required for packaging the pills.

In addition, the conventional pill packaging device cannot accurately determine the quantity of pills during the packaging process, and can check the quantity and weight of the pills after they are packaged, resulting in a decrease in production speed due to the addition of unnecessary processes.

The present invention was created to solve the problems of the prior art as described above, and an object of the present invention is to electronically check the weight through a load cell before the product is packaged in a packaging container, thereby eliminating the need for a defective checkweighing process after the existing packaging. The speed is greatly improved, and a cylindrical counting unit with an inlet opening for accommodating the product is provided on the outer circumferential surface to more accurately and quickly pack a predetermined number of products, and a load cell unit for checking the weight of the product contained in the lower part of the receptacle. It is to provide an integrated counter for each weight that can precisely measure products having a very small weight by checking the electronic load cell part.

The integrated counter for weight screening according to the present invention for achieving the above object includes a supply unit for dropping individual products in a downward direction, a packaging container for accommodating a predetermined quantity of products in the lower portion of the supply unit, and the packaging container in one direction In the counter for supplying a fixed quantity by sensing the weight of the product, the counter is provided between the supply unit and the packaging container and is provided with a counting packaging device composed of a moving conveyor,
