Description of the invention (/) The scope of the invention (please read the precautions on the back before filling this page) The present invention relates to a filling method and a filling device, a powder 'a granular material, a sheet Materials, a sheet, etc. (collectively called "material;) are sprayed into a container, such as cans, bags, rubber molds, stampers, etc. (collectively called 〃container〃), which has a feed An opening for the material and a container space filled with powder, etc. Prior technology The present applicant has proposed a filling method, such as disclosed in the prior patent application KOKAIH9-78103'KOKAIH9-169301 '^ l K0KAIH11 -4 9 1 0 1 in Japan, in which the container, can, bag, rubber mold, press Molds and other materials are filled with materials by air split method. In adopting such an air filling method, the difference in the amount of material during each filling is reduced, and the regional difference in the filling density of the material in the container is also reduced. Referring to Figures 5, 6 and 7, the conventional charging method will be described in detail. In this method, a die and a punch inserted into the die form a container so that a powder can be injected into the container. The part (1) shown in Figure 5 printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is a cylindrical die, and the part (2) is a punch inserted into the die (1) (the punch is subsequently Called His Majesty Punch "). A powder is filled in the die chamber (3), which is a space formed by the die (1) and the lower punch (2). The platform (4) is configured so that its upper surface and the die ( 1) The upper surface (1 a) is flush. A box-shaped bottomless feed element (hereinafter referred to as a "feed block") (5) is installed on the platform (4). The feed block (5) is provided with a duct (6) on the outer wall of the reduced part and an air extraction. The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297). Fly / ⑽ // A7- -------- Β7__ V. Description of the invention (&); A duct (8) connected to the outer wall (5a) of the feed block (5) is connected to a compressed air supply (10) via a solenoid valve (9). The other part (1 1) is a cover which is mounted on the upper opening of the part (5 a) of the feed block (5). The feed block (5) is filled with powder (p). The horizontal cylinder (12) is fixed on the platform (4). A piston rod (12a) mounted on the horizontal cylinder is connected to the feed block (5). In order to fill the powder (p) into the die chamber (3) formed by the die (1) and the lower punch (2) inserted into the die (1), a feed die (4) mounted on the platform (4) 5) The horizontal cylinder (12) is driven to move, thereby moving the piston rod (12a) until the feed block (5) is positioned above the mold chamber (3), as shown in Figure 6. Then the powder (p) stored in the feed block (5) is dropped into the mold chamber (3). Subsequently, the suction-type vacuum generator (7) is operated with the solenoid valve (9) closed, so that the air in the feed block (5) is exhausted. Therefore, the air pressure in the feed block (5) is from atmospheric pressure. State (a) is changed to state (b) below atmospheric pressure. Fig. 7 shows an example in which the low-pressure state (b) is 0.5 atmospheric pressure. Then, stop the operation of the suction-type vacuum generator (7) and open the solenoid valve (9), and the feed block (5) is supplied with compressed air from the compressed air supplier (10), and then the feed The air pressure state in the block (5) becomes a state at least higher than the above-mentioned air pressure state (b). In Fig. 7, the air pressure in the feed block becomes 0.8 atmospheric pressure and then higher than the air-pressure state (b). When the air pressure in the feed block (5) becomes higher than the air pressure state (b) which is lower than the atmospheric pressure, the solenoid valve (9) is closed again, and the suction vacuum generator (7) is operated to make the feed The inside of block (5) becomes lower than atmospheric pressure. -4- This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page).

State (b) of the invention description (4). Subsequently, the operation of the suction vacuum generator (7) was stopped, and the solenoid valve (9) was opened, so that the inside of the feed block (5) was supplied with compressed air. Therefore, the inside of the feed block (5) The state changes from an air pressure state (b) to an air pressure state (c) higher than the air pressure state (b). As described above, the air shunt method is used, in which the state of air pressure inside the feed block is repeatedly changed from a state (b) below atmospheric pressure to a state (c) having a higher pressure than the state (b), and the die 1 and The die chamber (3) formed by inserting the lower punch (2) therein can be uniformly filled with powder (p) and high-density. After the powder (P) is packed in the mold chamber (3), the horizontal cylinder (12) is moved to retract the piston rod (1 2 a), thus' moving the feed block (5) from the mold chamber (3) and re- Positioning. Then, an upper punch (not shown) is inserted into the die (1) and lowered to press the powder (p) packed in the die chamber (3) to obtain a compacted powder. The traditional method of filling and filling in the invention to be solved is not implemented by air shunting, but only by gravity. The traditional method suffers from the following problems: each time the material is filled, the quantity of the material is different, and the density of the material is localized in the container. When changing many containers at the same time, the filling amount in each container is not consistent. In particular, when a mold chamber having a complicated shape or a shallow ring shape is filled with powder without using air. Diversion filling method ', the unevenness of the density of the material in the mold chamber may damage the quality of the product. The above problems can be prevented when the material is filled into the container using air splitting. However, in the above-mentioned conventional air shunting method and device, the implementation of air shunting is to use repeated alternating changes of the air pressure state and apply the Chinese National Standard (CNS) A4 specification (210 X 297 public love) from this paper size (please first Read the notes on the back and fill in this page) ----- I--Order -------- Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 2. Description of the invention (4) State below atmospheric pressure (b) Switch to a state where pressure is higher than state (b) (c) 'When the air pressure inside the feed block (5) is lower than atmospheric pressure' Something went wrong. That is, the air outside the die chamber (3) flows into the die chamber (3) through the gap between the inner wall (1 b) of the die (1) and the outer wall (2 a) of the lower punch (2). Within this, the airflow may blow away the powder (P) that has been installed in the inner chamber (3) of the die. In addition, when the powder is filled into the rubber mold 17 shown in FIG. 3 by the conventional air shunt method, since the rubber mold 17 'is in a low air pressure state during the air shunting process, the internal air pressure state is lower than Atmospheric pressure, it is necessary to use a device to make the state outside the rubber mold into a low air pressure state to prevent the rubber mold from deforming inward. Such preventive measures complicate the structure of the device and cause the device to be expensive 'and prone to failure. The object of the present invention is to solve the problems encountered by the conventional method and device of material extraction.

Description of the Invention (r) Figure 6 is a vertical cross-sectional view of another traditional material device. Figure 7 is an operating graph showing air pressure switching when conventional air shunting is applied. In order to achieve the above-mentioned object, the present inventors have devised a new method of feeding materials, in which the implementation of air distribution is to use the air pressure of a space to switch.

The pressure release valve (13) is designed to be able to exhaust the air in the feed block (5) when the air pressure in the feed block (5) is higher than the atmospheric pressure to a certain degree. An air vent (14) is formed in the wall of the reduced portion (5 a) of the feed block (5), which is similar to the traditional method 'in order to fill the mold chamber (3) with powder (p), the mold chamber is ^ The die (I) and the lower punch (2) inserted into the die (1) are formed, and the feed block (5) mounted on the platform (4) is moved by driving the horizontal cylinder (12) to move The piston rod (12a) until the feed block (5) is positioned on the inner chamber (3) of the die as shown in Fig. 6. Then, the powder (5) stored in the feed block (5) Then it descends into the mold chamber (3). Then the 'solenoid valve (9) is opened' and supplies compressed air from the compressed air supplier (10) to the feed block (5), so that the feed block (5) The air pressure inside) is changed to an air pressure state (B0) that is higher than the atmospheric pressure (A0).

The above process is similar. When the pressure of the air supplied from the compressed air supplier (10) and enters the inside of the feed block (5) exceeds the tolerance of the pressure relief valve (13), the air The pressure release valve (13) is released. Then, the solenoid valve (9) is closed to stop the supply of air from the compressed air supplier (10) into the feed block, and the feed block (5) is at a high level. The air in the air pressure state (B1) is naturally discharged from the air release hole (14), which can reduce the air pressure inside the feed block (5) to the atmospheric pressure shown in (A2) in Figure 2 As mentioned above, the repeated operation of air shunting is used, in which the state of air pressure inside the feed block is changed from a state higher than atmospheric pressure to a state equal to atmospheric pressure, so that the powder (p) can be uniformly charged in The die chamber (3) formed by the die (1) and the lower die (2) is inserted therein, and the density is increased. After the powder (P) is filled in the mold chamber (3), the horizontal gas (12) is moved to retreat the piston rod (12a), so that the feed block (5) leaves the mold chamber (3) and restarts Positioning. Then, the upper punch (not shown) is inserted into the die (1) and lowered to compact the powder filled in the die chamber (3) to produce a compacted powder. In this embodiment, the air shunting is implemented by repeatedly changing the air pressure state, wherein the state is changed from a state higher than atmospheric pressure to an atmospheric pressure state, so that air outside the mold chamber (3) is not allowed to pass through the inner wall of the mold. The gap between (1 b) and the outer wall (2a) of the lower punch (2) enters the die chamber (3). Therefore, the situation where the powder (P) is blown away by the air can be prevented from occurring. In addition, the air shunt can repeatedly switch the air pressure state at appropriate times, and from the high -9- this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm)---------- ---- · III (Please read the notes on the back before filling out this page) tx --------- line 474877 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V.

The description of the invention is reduced to allow the rubber mold (17) to shrink inward and compress The powder which has been packed in the rubber mold (17) can thus produce a compacted powder. In the conventional method, the air shunting process is implemented by alternately changing the state of the air pressure in the cylindrical guide (23) from a state lower than the atmospheric pressure (b) to a state higher than the state (c) . In this case, when the state of the air pressure in the inner cavity (17a) of the cylindrical guide (23) and the rubber mold (17) becomes lower than the atmospheric pressure, the outer wall of the rubber mold (17) and the The atmospheric pressure existing between the inner walls of the die (15) pushes the rubber die (17) 'and deforms the rubber die (17) inward.

Description of the invention (* 4) In traditional materials In the method, when the bag (27) is packed with powder (p), the implementation of the air shunt is to change the air pressure state from a low air pressure state (b) lower than the atmospheric pressure to a state higher than the state (b) The air pressure state (c) occurs when the air pressure state inside the cylindrical guide (28) and the bag (27) becomes a low air pressure state (b) lower than the atmospheric pressure. In other words, since When the air between the bag (27) and the bag-holding container (26) flows in, the bag (2 7) will Internal deformation. Because the present invention adopts the air shunt method, the bag (2 7) is closedly installed on the inner wall of the bag-holding container (26), and the air pressure state is alternately changed from a high air pressure state higher than the atmospheric pressure When converted to the atmospheric pressure state, the deformation of the bag (2 7) will not occur. As described above, the present invention allows the material to be filled to be uniformly filled in the container. This effect can also be achieved if the following steps are adopted: the container At first, the material was loaded by using other decoration methods or traditional decoration methods, and covered with a cover block with the same structure as the above-mentioned feed block, but it did not carry the material to be installed (this block is called the cover block after storage) 〃). Then, the cover block is subjected to a cyclic effect, in which the air pressure state in the cover block is changed from a high air pressure state to a low air pressure state, and at the same time, the air pressure is higher than or equal to the air pressure outside the container (under normal conditions, Atmospheric pressure). Therefore, the material is uniformly packed in the container, and there is only a small scattering each time the material is poured. Although this method is compared with the other method, in which the feed and material are performed by the feed block that has previously carried the material, this method is disadvantageous in terms of productivity and uses the air of the cover block The shunt method is preferably adopted in the case of the following examples. -16- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm)---------I------II ^ ---- IIIII (Please (Please read the precautions on the back before filling this page) 474877 A7 B7 V. Description of the invention (&); When a container with a complex shape or a shallow ring is used to load powder with a high degree of weight control and dimensional accuracy, it is most commonly used The powder is weighed by a high-precision weighing device according to the amount of powder to be loaded into the mold chamber and fed into the mold chamber. At this stage, the decoration density in the mold chamber is extremely uneven. Then, the cover block is installed on the top opening of the mold chamber and is subjected to air split processing. This process enables the powder to be filled with large uniformity and high precision in each corner of the inner chamber of the complex-shaped die or filled in the peripheral wall of the shallow annular chamber. Different from the conventional air shunt method, the amount of powder in the decoration may be changed due to the blow-off of the powder, while the air shunt method of the present invention does not change the amount of powder at all. Therefore, a compact or shallow-ring compacted powder whose weight and shape are precisely controlled can be produced using the present invention. If the material to be decorated is a combustible powder, etc., the air used in the air split may be an inert gas such as nitrogen or argon. The air in the above embodiments is not limited to air, but also includes inert gases such as nitrogen and hydrogen. The structure of the present invention as described above has the following effects. Because the implementation of the air shunt method is to keep the air pressure state equal to or higher than the atmospheric pressure state, the problem that the material contained in the space is not scattered by the air flowing in from the outside of the space will not occur. The device of the present invention does not need to be provided with a tool for preventing deformation of the container, because the air shunting method is implemented to keep the air pressure state higher than or equal to the atmospheric pressure state. The structure of the device may thus be simplified. -17- The size of this paper is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) Loading -------- Order ----- --- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by 474877 A7 _B7_ V.
