Description

Apparatus for filling bags with the particles of contents, having an improved interception of the contents}

The present invention relates to a device for filling particulate contents with improved leakage blocking function. More particularly, the present invention relates to a device for filling a particulate content into a product to prevent unnecessary leakage of residual material. The present invention relates to a device for filling particulate content with improved blocking function.

In general, in the case of filling the product container with the contents in the form of particles such as seasonings, etc., the contents coming out of the auger tube by connecting a trumpet-shaped auger tube under the hopper containing the filling contents. It is intended to be put into this product container. In the auger tube, the spiral screw rotates to push the contents out. If the remaining amount of the contents falls even after the filling of the contents into the product container, a sticky seasoning, etc. is installed outside the product container to contaminate the packaging equipment. In addition, in consideration of the amount of leakage, the overall amount of contents to be put into each product container should be increased, so that the rate of abolition {= (amount injected additionally beyond the quantity of the product) / (quantity of the product)} There is a problem in that the raw material costs rise.

In order to prevent the problem of leakage of the residual amount of the contents in the conventional contents filling apparatus is attached to the bottom of the auger tube or a spinner (spinner) so that the contents remaining on the top of the list or the spinner.

Hereinafter, the remaining amount leakage preventing means of the conventional contents filling apparatus will be described with reference to FIGS. 1A, 1B, and 1C.

FIG. 1A is a schematic perspective view of a conventional contents filling apparatus for filling the contents in the form of particles, and FIG. 1B is a detailed view of the leakage blocking barrel 40 and the list mesh 42 installed in the lower portion of the conventional contents filling apparatus. Fig. 1C shows that the spinner 43 is installed in the leakage blocking cylinder 40 of the conventional contents filling apparatus.

Referring to FIG. 1A, when the contents in the form of particles are filled in the supply hopper 12 through the product supply chute 11, the contents detection sensor 13 of the supply hopper 12 operates to maintain the contents at a constant height. do. The agitating rake 32A, which is connected by the rotation shaft 24 and the flange in the main hopper 31, is rotated by the edge-taking motor 22 and evenly agitates the contents in the main hopper 31. The rotating shaft 24 is connected to the servo motor 21 to rotate, and the lower end of the rotating shaft 24 is fastened to the upper end of the auger screw 34. The auger pipe 33 is coupled to the exit near the bottom vertex of the main hopper 31. A thread tab is formed on the outer circumferential surface of the lower end of the auger tube 33 to couple the leakage blocking tube 40 to each other. In the inner empty space of the leakage blocking cylinder 40, a list network 42 shown in Fig. 1B is installed.

The servo motor 21 rotates or stops according to an operation control signal applied from a separate control device. The servo motor 21 rotates while the contents are filled in the product container 50, and when the next product container moves to the correct position after the filling is completed. Stop until When the servo motor 50 stops, the auger screw 34 also stops and does not push the contents any further. However, even after the auger screw 34 stops, the contents are leaked due to inertia, and the leakage amount is accumulated on the list network 42. In consideration of the shape, density and size of the filling contents and the entanglement state between the particles, the list network 42 is designed so that the content particles stacked on the list network do not fall down unless a separate force is applied.

However, since the existing list network is designed for the content particles having a constant size, density, size and entanglement, when the size and shape of the granules of the content particles change due to the change in the manufacturing process, the flow direction and leakage of the residual amount Due to the difference in degree, there was a problem that can not effectively perform the leakage blocking function. In other words, when the granules of particles such as seasonings are improved, and a difference with the existing particles occurs, the previously used list network cannot be used at all for new particles.

As an alternative to this problem, a dish-shaped spinner 43 has been used instead of the list mesh 42. That is, the spinner 43 is installed inside the leakage blocking tube 40 including the lid 40A and the body 40B, and fixed by the protruding jaw 43A, and then the auger screw 34 is rotated and stopped. If the leakage residual amount is piled up like a pile on the spinner 43 does not fall down. However, although the method using the spinner 43 is effective to prevent the leakage remaining directly on the packaging device, the charging speed is slower than that of using the list network, and if the list network is used, the list network There is a problem that the mass to be crushed and crushed into the product container as it is difficult to use.

The present invention is to solve the above problems, regardless of the size, density, shape of the contents of the filling content always flows down in a certain direction and after the product is finished, the complete leakage blocking function to exert a noxious loss It is an object of the present invention to provide a filling device for particulate contents that reduces costs and reduces costs and does not pollute the surrounding environment.
