Abstract

PURPOSE:To fill pulverized/granular substance so that the grain surfaces are level, by rotating a disc whose undersurface is provided with radially stretching ridges, and sinking it in rotation on the top of a bulged surface of pulverized/ granular substance formed in a cylindrical container, whose top is open. CONSTITUTION:A certain amount of pulverized/granular substance 6 is self-heat dropped into a cylindrical container 1, to form a bulged surface of pulverized/ granular substance, as shown in attached illustration. A disc 13 provided at the undersurface with vanes in the form of radially stretching ridges 13a is rotated and put on the top 6' of this pulverized/granular substance. The substance 6 in this part is also rotated and moved to the periphery within said cylindrical container 1, and now the substance 6 will be in contact with the whole area of the sunk and rotating disc 13. If here the disc 13 is lifted while rotation is held, the top of the substance will become level and uniform throughout the surface, to accomplish intended fine filling of pulverized/granular substance.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is capable of uniformly filling a container with a certain volume with powder or granules.
This invention relates to a method that is particularly suitable for automatic execution.

(Prior Art) A spinning pack is attached to the lower part of a spin block of a melt spinning device, which is a device for performing melt spinning of synthetic polymers. A spinning pack generally includes an ingot 21 into which a spinneret 22, a wire mesh filter 23 with a rim, and a rectifying plate 25 are sequentially inserted, as shown in FIG. Intermediate packing 26. An ingot 24 filled with powder 6 such as sand and sequentially inserted with rings 2 having rimmed wire mesh filters 3 and 27 at the upper and lower parts.
and an ingot 28 having a polymer flow path 29 are respectively fastened with bolts (not shown). Traditionally, such spinning packs have been assembled by hand, but manual assembly requires skill, makes it difficult to arrive at each part accurately and evenly, and is difficult to measure and fill the sand. There is a problem in that it cannot always be performed accurately and uniformly. Therefore, in order to solve the problem of manual assembly, we investigated the possibility of replacing the assembly with an automated machine.

As a result, it was found that it was not possible to uniformly fill the sand with the manual method in order to assemble it using automated machinery, so we conducted an investigation to establish a method suitable for assembly using automated machinery. As a result, the present invention was achieved.

(Object of the Invention) An object of the present invention is to provide a method for automatically filling a container with powder or granules to an even height using an automated machine.

(Means for solving problems) The present invention consists of the following configuration to achieve the above object.

After the powder is allowed to fall naturally into a cylindrical container with an open top to form a convex powder surface, a spring body is placed between the rotating means and the top of the convex powder surface, and the powder is moved up and down. A disk having a plurality of suspended radial protrusions formed on its lower surface is placed, the disk is rotated and lowered until the disk almost comes into contact with the powder, and then the rotation is maintained. This is a method for filling powder and granules, which is characterized by holding the powder on its back and separating it from the surface of the powder.

(Example) Hereinafter, the present invention will be explained based on the drawings. FIG. 1 is a general schematic diagram of an apparatus for carrying out the method according to the invention.

In the figure, reference numeral 1 denotes a cylindrical container fixed to a substrate 40 by gripping claws 5 provided on the opening/closing angle surface, and is composed of a ring 2 and a rimmed wire mesh filter 3 fitted into its bottom stepped surface 2'. The cylindrical container 1 may be of any type as long as its upper end is open, but it is preferable that the cylindrical container 1 has a cross-sectional structure as shown in the figure.

When the cylindrical container 1 is placed on the substrate 4 by an automatic pick-up method or an industrial robot (not shown), the gripping claws 5 are closed by the operation of an air cylinder (not shown) and the cylindrical container 1 is fixed. Next, when the supply port of the measuring device (not shown) moves onto the cylindrical container 1 and allows a certain amount of powder and granules 6 to fall naturally, the powder and granules 6 accumulate in a mountain shape inside the cylindrical container 1 as shown by the dotted line. becomes.

The falling amount of the powder and granular material 6 is a pre-measured amount, and
It may be changed arbitrarily as long as it remains within the range. By repeating the procedure described below, it is possible to fill not only one type of powder or granular material 6 but also multiple types of powder or granular material 6 uniformly (height) without mixing. The falling amount of powder and granular material is such that the entire amount filled into the cylindrical container 1 remains within the cylindrical container 1.

When a predetermined amount of granular material 6 is supplied to the cylindrical container 1, the rotating disk 13 placed above the cylindrical container 1 is lowered and brought into contact with the top surface G' of the granular material 6 as shown by the dotted line. . Rotating disk 1

have. The cylindrical body 9 has a first hollow part 11 . A second square cross section is shown below.
It has a hollow part 12. The rotating disk 13 has a support shaft 14 vertically protruding from its center position, and the support shaft 14 has a rectangular cross section that fits into the second hollow part 12 of the cylinder body 9 and transmits rotational force. Square column part 15. Next to the prismatic part 15, there is a cylindrical part 1 having a diameter slightly smaller than the diameter of the throat part 10 of the cylindrical body located above the prismatic part 15.
64, this cylindrical part 1G is inserted from the second hollow part 12 of the cylindrical body 9 through the throat part 10 and is suspended from the cylindrical body 9 so as to be vertically movable by a nut 18 screwed to the upper end part. There is. A coiled spring 17 is inserted into the second hollow part 12 of the cylindrical body 9 and is connected to the square column part 15, so that when a force in the -L direction is applied to the rotating disk 13 (the nut 18 10'
When the object floats further upward), a reaction force is generated. Further, a plurality of radially extending protruding blades 13a are formed on the lower surface of the rotating disk 13 as shown in FIGS. Incidentally, the prismatic portion 15 is configured such that at least its upper portion is contained within the second hollow portion 12 with the nut 18 in contact with the stepped surface 10'. As mentioned above, the rotating disk 1 is placed on the top 6' of the powder surface.
3 is placed while rotating, and the rotational speed at this time is adjusted in advance to such an extent that the powder or granular material 66 (not scattered due to rotation).

Further, the lowering position of the disk 13 is set in advance so that the lowering position of the disk 13 is below the level of the powder produced when the powder 6 is uniformly filled into the cylindrical container 1 while the disk 13 is being pushed out by the spring 17. I'll keep it.

Immediately after the rotating disk 13 is placed on the grain surface, the spring 17 is compressed and contracted upward due to the reaction force of the powder 6, but due to the rotation, the powder grain at the top As the body 6 gradually moves to the periphery of the cylindrical container 1, it gradually descends while remaining in contact with the top of the powder surface, and eventually the entire area of the rotating disk 13 comes into contact with the powder 6.

Protruding blades 13a are provided on the lower surface of the rotating disk 13, and the blades 13a are preferable in order to smoothly move the powder particles 6 accumulated in a mountain shape from the center of the cylindrical container 1 to the periphery. The shape should preferably be such that it recedes in the direction opposite to the direction of rotation as it approaches the edge.

As described above, the granular material 6 can be filled into the cylindrical container 1 almost to an even height, but when the rotation of the disk 13 is stopped in this state and the disk 13 is lifted, the powder surface is filled with the lower surface of the disk. Since the protrusion remains, the disk 13 (motor 7) is slowly lifted using a vertical movement device (not shown) while continuing to rotate.

In this way, the particle surface of the powder material 6 is horizontally and uniformly filled over the entire surface of the cylindrical container.

As the vertical movement device, for example, a neck device that uses an air cylinder to perform vertical movement, a method in which the industrial robot 1 includes a rotation generating element (motor) and is gripped, etc. are adopted.

The rotating disk 13 has a structure that allows it to move upward in response to a (compression) spring 17 when a force is applied from the lower part of the rotating disk 13 to overcome the spring as a reaction force of the load from the vertical movement device. (See the two-dot chain line in Figure 2). By providing this mechanism, the rotating disk 1 ．． The lower limit position of the motor 7 including the support shaft 14 can be kept constant.

<Effects of the Invention> As described above, according to the present invention, powder and granules can be filled into a container with an open top using an automated machine so that the grain surface thereof is horizontal.

Furthermore, it is possible to uniformly fill a plurality of types of powder and granular materials in a container in a layered manner without mixing them with each other.

INDUSTRIAL APPLICABILITY The present invention can be widely applied as a method for filling powder or granular materials using automated machinery. Specifically, for example, when a powder or granule is incorporated into a spinning pack as one of its parts, the powder or granule can be incorporated while being filled in a container, so it is effective for assembling a spinning pack for synthetic polymers. Can be used.
