Description

[Detailed description of the invention] [Industrial application field] This invention automatically stores powder and granules through the throat of a container bag made of cloth or plastic used for storing and transporting powder and granules for the ceramic industry. The present invention relates to a powder storage container that can be attached to the chute of the container.

[Conventional technology]

When filling a container bag with powdered raw materials or products from a powder storage container such as a hopper or mixer, the filling operation is often performed manually. For example, when attaching a container bag to the powder discharge chute of a powder storage container such as a hopper or mixer, an operator opens the throat of the container bag, places it on the chute, and then manually He had his throat inserted into his chute.

[Problem that the invention attempts to solve]

However, the work of attaching the throat of a container bag to the lower chute of a container storing powder or granular material is usually carried out in a dirty environment with floating dust. For this reason, such work has tended to be avoided by workers.

Furthermore, such mounting work is often carried out in places with poor working conditions, such as on top of hoppers or scaffolding, which can cause fatigue to the workers. Furthermore, when loading powder into a container bag from a hopper or the like located above the second or third floor, workers are forced to work on multiple floors. That is, manual work such as attaching the throat and filling powder and granules is not desirable from the viewpoint of reducing the number of personnel.

The present invention was developed with the aim of automating the installation of the throat of a container bag in view of such problems in manual work.

[Means for solving problems]

In order to achieve this purpose, the container for storing powder and granular materials of the present invention has a vertically movable shaft with a suction tool attached to the rim of the throat of the container bag that adsorbs the object to be adsorbed. It is characterized by being arranged around the outer periphery of the chute of the body storage container.

[Effect]

When the shaft with the suction tool attached is lowered onto an empty container bag placed at the filling position directly below the powder storage container, and the adsorption material at the end of the hanger of the container bag is adsorbed, the suction tool is inserted into the upper throat. so that the lip of the upper throat of the container bag flares concentrically with respect to the mouth of the chute. Next, when the shaft with the adsorbed material in the container bag is pulled up, the upper throat is opened and attached to the outer circumference of the chute, and the powder and granules are filled from the chute into the container bag, and the powder and granules are Automation of bag filling is achieved.

〔Example〕

Hereinafter, features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 is a diagram showing the powder storage container in this embodiment together with the upper half of the container bag.

The powder storage container 1 has a chute 2 below it.
have. A telescopic shaft 4 that is extended or retracted by a drive mechanism 3 is arranged on the outer periphery of the chute 2 . This shaft 4 is
Preferably, a plurality of them are provided at equal intervals along the outer periphery of the chute 2. At the tip of each shaft 4,
A suction tool 5 is attached.

In addition, in FIG. 1, the reference numeral 9 indicates a mouth fastener that utilizes the shape restoring force of a shape memory alloy that is employed as necessary. By blowing hot air from the fan 10 while the upper throat 7 is rising, the closure 9 is heated and changed in shape, making it possible to automatically open the container bag 6. . The heating of the mouth fastener 9 is not limited to blowing hot air, and other appropriate heating means such as heat ray irradiation, electrical heating, etc. can be employed. Also, the number 11 is
Hangers are shown that can be attached to both sides of the container bag 6 if necessary. By magnetically attaching the magnetic adsorbent 12 attached to the tip of the hanger 11 with the electromagnet 13 suspended from above and lifting it, it is possible to automate the standing up of the container bag 6 during powder filling. becomes.

In this embodiment, the container bag 6 is raised and lowered by lifting the magnetic adsorption body 12. However, the present invention is not limited to this, and the container bag 6 can also be raised and lowered by expanding and contracting the shaft 4.

FIG. 2 shows an example of a magnetically attracted object. This adsorbed body 8a also functions as a cap for the upper throat 7, and is formed into two folds in the example shown in FIG. And each divided piece 8a ₁
A stopper 14 is provided on the periphery of each of the divided pieces 8a2 and _8a2 , which is engaged with the periphery of the opposing divided piece.
When the container bag 6 is open, the adsorbed body ₈ is in the _state shown in FIG. is in a state of

Further, FIGS. 3a and 3b show an example of a vacuum suction type object to be sucked and a suction tool, respectively. Similar to the example shown in FIG. 2, this adsorbed body 8b also functions as a base for the upper throat 7, and has a bifold structure.
The suction tool in this case is a vacuum chuck 5b having a shape corresponding to the object to be sucked 8a, and the vacuum chuck 5b is arranged to be vertically movable with respect to the chute 2 by the shaft 4. After the vacuum chuck 5b is lowered to fit the object 8b, the space between them is evacuated via the hose 15. In this state, the upper throat 7 can be lifted toward the chute 2.

In FIGS. 2 and 3, a bifold circular object is shown as the adsorbed object, but the object is not limited to this, and an integrally molded object, a square object, etc. can be used as appropriate. Moreover, such an adsorbed body can be made of various materials such as metals and plastics.

Next, referring to FIG. 4, the procedure for attaching the upper throat of the container bag to the chute of the powder storage container will be explained.

FIG. 4a shows the state in which the empty container bag 6 carried out from the storage case is placed in the filling position directly below the powder storage container 1. From this state, the pair of electromagnets 13 are lowered to attract the magnetic adsorbent 12 at the tip of the hanger 11. Next, the electromagnet 13 is lifted. This is the state shown in FIG. 4b. Then, the drive mechanism 3 lowers the shaft 4 with the suction tool 5 attached to the tip thereof, and as shown in FIG. At this time, since the suction tool 5 is arranged around the upper throat 7, the object to be attracted 8 is attracted to the suction tool 5, so that the lip of the upper throat 7 is placed against the mouth of the chute 2. It spreads concentrically. In the process of lifting the upper throat 7 by the drive mechanism 3, the mouth clamp 9 attached to the upper throat 7
is heated by the hot air sent from the fan 10, deformation peculiar to the shape memory alloy occurs, and the upper throat 7 is automatically opened. As a result, the opened upper throat 7 is attached to the outer periphery of the chute 2, resulting in the state shown in FIG. 4d. In this way, the powder and granular material is filled into the container bag 6 from the chute 2.

In addition, when using the adsorbed body 8 as shown in FIG. 2 or FIG. 3 in the upper throat 7, the mouth of the upper throat 7 is opened by human power, mechanical power, or the like.
That is, it goes without saying that no heating operation is required for the mouth fastener 9 provided with the shape memory alloy.

Alternatively, as shown in FIG. 4c, a method may be adopted in which the suction tool 5 is lowered and adsorbed onto the object to be sucked 8. In this case, by applying a lifting force to the suction tool 5, the upper throat 7 can be attached to the chute 2 without the need for the electromagnet 13.

[Effect of idea]

As explained above, in the present invention, it has become possible to automatically attach the throat of the container bag to the chute of the powder storage container. Therefore, there is no longer a need for workers to carry out filling operations under poor working conditions with floating dust. Furthermore, since the installation work can be done by remote control, the number of workers previously required for filling work can be reduced.
