Abstract

PURPOSE:To easily weigh and mix >=2 kinds of material by one device by forming measuring chambers in >=2 arrays concentrically with a rotary disk, and supplying different materials to the respective arrays and measuring them in the weighing chambers. CONSTITUTION:When a driving source 6 is driven to rotate the rotary disk 20, the material A of a 1st material supply source 2 is supplied to the measuring chamber 21 of, for example, the 1st array at a specific position of the disk 20 between the measuring chambers 21 and 22 which are provided in >=2 arrays concentrically with the disk 20 and the disk 20 is further rotated and displaced to supply the material B of a 2nd material supply source 3 to the measuring chamber 22 in the 2nd array and the material C of a 3rd material supply source to the measuring chamber 21,..., thereby measuring the materials A, B, and C... by a specific amount respectively. Then the measured materials are supplied into a chute 17 through a material discharge opening 11 provided to a base 10. The chute 17 supplies the respective material by the specific amount continuously and they are mixed uniformly by colliding against one another, so a mixing means is not required specially.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable, for example, to a synthetic resin molding machine when a mixture of multiple types of materials such as plastic raw materials, colorants, additives, and different types of plastic raw materials is supplied. The present invention relates to a rotating disk type metering and feeding device for metering various materials.

[Conventional technology]

Conventionally, this type of rotating disk type metering and feeding device has been
For example, Utility Model Publication No. 54-1188 related to the applicant's application.
As described in Publication No. 9, a hopper for storing materials is connected to a base having a material discharge port, and a rotating disk is rotatably stored in the open space at the top of the base, and the same circular One metering hole of a constant size is placed at regular intervals on the circumference.
It is known to have multiple holes in a row. It is also known that one annular groove is used as a metering portion instead of the plurality of metering holes.

[Problem to be solved by the invention]

However, when measuring materials using a plurality of measuring holes or one annular groove in the above-mentioned rotating disk type metering/feeding device, only one type of material can be measured.

Therefore, for example, when weighing and mixing multiple types of materials such as colorants and different types of plastic raw materials into plastic raw materials, separate measuring instruments have been used for each different material. Each weighing device is equipped with a sensor, counter, timer, etc. to measure each material.
The mixing ratio was determined by measuring the number of rotations of the rotating disk and the number of measuring holes.

Therefore, as mentioned above, this conventional example requires a large number of component control parts such as measuring instruments, sensors, counters, timers, etc. for each type of material, resulting in an expensive weighing device, and a large number of these component parts. There were problems such as the need for a large installation space.

The present invention aims to provide a method that eliminates all of the problems of the prior art by making it possible to measure and mix a plurality of types of materials using a single measuring device.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a rotating disk type metering and feeding device that includes at least a base having a material discharge port and a rotating disk rotatably housed in the base. Two or more rows of measuring chambers are formed on the concentric circle of the rotating disk, and the volumes per unit of the measuring chambers are the same or different, and different materials are supplied to each row to form each measuring chamber. In addition to weighing with
A device equipped with one or more material discharge ports that mix and discharge the materials filled in each row of measuring chambers by rotating and displacing them, and a chute that collects each material discharge port in one place. It is.

The measuring chambers provided in two or more rows may be formed in two or more rows in the lateral direction on different concentric circles extending from the center of the rotating disk toward the outer circumference, as shown in the examples described later.
Two or more levels (layers) may be formed in the vertical direction on one concentric circle, and two or more rows may be formed in the vertical direction, or at least one or more rows of measuring chambers may be formed in the horizontal direction of the former, and the measuring chambers may be formed in the upper and lower directions of the latter. It may be a combination of two or more rows of measuring chambers arranged in stages in the direction.

When supplying different types of materials to the measuring chambers in different rows, they can be supplied from different material supply sources, or the interior of a material supply source such as a single hopper may be divided into two or more sections, and the plurality of materials may be supplied from different sources. It is also possible to have a structure in which different materials are stored in each of the storage chambers, and the materials in each storage chamber are supplied to the measuring chambers in different rows.

The upper surface of the weighing chamber is ground with a slotted plate to adjust the amount of material filled into each weighing chamber.

Further, by inserting a scraper into the measuring hole or the annular measuring groove forming the measuring chamber, a total of 111 feet can be finely adjusted. The soufflé par may be fixed, but it is preferable to use one that can move up and down. However, this scraper can also be used without one.

The material outlet formed in the base is shaped like a bead, for example, by expanding sequentially from the smaller diameter part to the larger diameter part than the measuring chambers in each row, facing the same direction as the rotation of the rotating disk. When formed, there is an advantage that various materials can be discharged in a continuous manner at the material discharge port, but the shape can be arbitrary.

When at least one of the material supply sources that supplies materials to the measuring chamber of the rotating disk is configured to include a plurality of material supply pipes and a switching means that arbitrarily selects and switches the material supply pipes, the material A wide variety of materials can be selected from various sources.

[Effect]

When the rotating disk is rotated by driving the drive source, among the measuring chambers provided in two or more rows on the concentric circle of the rotating disk,
At a predetermined point on the rotating disk, material A of the first material supply source is supplied to, for example, the first row of measuring chambers, and by further rotationally displacing the rotating disk, material A is sequentially supplied to, for example, the second row of measuring chambers. 2
Material B from the material supply source is supplied, for example, material C from the third material supply source is supplied to the measuring chamber in the first row, and materials A, B, C, etc. are each fed as desired using a cutting plate or a scraper. Add needles in small amounts.

Various materials weighed in desired amounts (material A, material B, material C...)
The material is supplied through one or more material outlets formed in the base into a chute that collects each material outlet in one location. This chute continuously supplies a predetermined amount of each row of materials, that is, two or more types of materials, and the materials collide with each other so that they are evenly mixed as if they had been mixed by a mixing means, so a new mixing means is required. The above-mentioned mixing effect can be further improved if a baffle plate is provided inside the chute.

By configuring the material discharge ports to be sequentially widened from a diameter portion smaller than the measuring chambers of each row to a diameter portion larger than the measuring chambers in a bead shape, various materials can be discharged in a continuous state.
