TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for supplying and filling powders and granules (hereinafter, collectively referred to as powders and granules) composed of various materials into a package such as a flexible container bag, a paper bag, and the like. It is.
[0002]
[Prior art]
BACKGROUND ART In a wide range of industrial fields such as foods, pharmaceuticals, and chemicals, powders and granules made of various materials are used for manufacturing and processing products. These powders are stored in a package such as a flexible container bag or a paper bag when shipped from a manufacturer. In addition, the product manufacturer stores a mixture of powders and granules having different content components by a predetermined amount in a package such as a flexible container bag or a paper bag for storing or transporting the mixture to another place.
Usually, a flexible container bag is used for packaging a large amount of powder or granules of 300 kg or more, and a paper bag is used for packaging a small amount of powder or granules of 50 kg or less.
[0003]
2. Description of the Related Art Conventionally, a plurality of hoppers have been used when packing a granular material into a package such as a flexible container bag or a paper bag. For example, each hopper having an individual wrapping machine stores powders and granules having different content components, and the wrapper is connected to the hopper packaging machine containing the required powders and granules. The amount was filled. Alternatively, a plurality of hoppers accommodating powders and granules having different contents are connected to a single wrapping machine by a chute, and the wrapping body is connected to the lower side of the wrapping machine and filled. Was.
[0004]
[Problems to be solved by the invention]
However, if a wrapping machine is installed for each hopper, a large number of hoppers are required to handle a large variety of small and granular powders, so installing a wrapping machine for each hopper increases capital investment. The maintenance and inspection required a lot of time and personnel.
[0005]
In addition, when a plurality of hoppers and one wrapping machine are connected by a chute, the hoppers are usually arranged in a horizontal row, so the chutes between the plurality of hoppers located immediately above the wrapping machine are usually Since the powder is almost vertical, the powder can be smoothly delivered. However, the chute between the hoppers located at a position distant from the packaging machine has a gentle gradient, so that the flow of the powder and granules is poor, and a clogging phenomenon occurs on the way, so that filling may not be performed.
[0006]
For this reason, in order to connect the hopper remote from the packaging machine and the packaging machine with a steeply inclined chute, all hoppers must be installed at a high place, or at least the hopper remote from the packaging machine must be installed. It must be installed at a high place to keep a large distance from the packaging machine, resulting in a large-scale replenishment facility for powders and granules to each hopper, and also requires complicated cleaning work when changing varieties. Met.

Further, in the conventional filling apparatus, for example, as shown in Japanese Patent Application Laid-Open No. 7-33117, a gantry is installed perpendicular to the filling section, and an empty flexible container bag is sent from one gantry to the filling section. There was a problem that a large installation area was required to carry out the flexible container filled with the granular material from the other stand.
[0008]
The present invention has been made in view of the above-mentioned problems of the method and apparatus for packing granules, in which a plurality of hoppers containing granules having different content components are installed at the same plane height, and each hopper is located at a specific position. The present invention provides a packaging method and apparatus for supplying and packaging powder and granules to a package such as a flexible container bag or a paper bag by stopping at a time.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIGS. 1 and 2 show an embodiment of an apparatus used in the present invention. The apparatus comprises a granular material supply unit 1 and a granular material packaging unit 2.
The granular material supply unit 1 supplies a predetermined amount of the granular material to a flexible container bag or a paper bag, and the plurality of hoppers 3 containing the granular materials having different content components have the same plane height. Each hopper 3 is reciprocally movable in the X arrow direction and can be stopped at a predetermined position (specific point).
[0014]
Further, the granular material packaging section 2 has packaging carts 4 and 5 in which flexible containers and paper bags are set so that the granular material can be filled, respectively. Can be reciprocated in the direction of the arrow Y and can be stopped at a predetermined position.
[0015]
Next, the components 1 and 2 will be described in detail.
As shown in FIG. 1, the powder supply unit 1 includes a hopper 3, a truck 6 on which the hopper 3 is placed and which reciprocates in the X direction, and a rectangular frame 7 that supports the truck 6 so that the truck 6 can travel. ing.
As shown in FIGS. 2, 3, and 4, the hopper 3 having the cut gate 8 in the conical part formed at the lower part of the circular trunk has four mounting plates 9 on the side of the trunk horizontally in an orthogonal state. Each mounting plate 9 is protruded, and can be weighed on load cells 10 installed at four corners of the carriage 6.
[0016]
The truck 6 and the mounting plate 9 of the hopper 3 are connected by a connecting member 11 so as not to rotate in the circumferential direction. For example, as shown in FIG. 5, the connecting tool 11 may connect the upper surface of the carriage 6 and the lower surface of the mounting plate 9 with one bolt 12, and the bolt 12 bends vertically by the load of the hopper 3. Therefore, the mounting plate 9 is stably mounted on the load cell 10. Note that the load cell 10 detects the volume of the granular material in the hopper 3 and is not necessarily required.
[0017]
The cart 6 has a pair of wheels 13 in the front and rear direction of travel, and the wheels 13 are mounted on rails 14 laid on the support frame 7. Then, as shown in FIG. 6, by connecting a sprocket 16 of a reversible motor 15 mounted on the carriage 6 and a sprocket 18 of one axle 17 by a chain, the wheels 13 are rotated by the drive of the motor 15 and the carriage 6 can run on the rail 14. Although the shapes of the left and right wheels 13 are different in the drawings, at least one of the wheels 13 only needs to fit and rotate with the rail 14, and the other wheel 13 only needs to be mounted on the rail 14.
[0018]
The packaging carts 4 and 5 are, for example, those in which the packaging cart 4 installs flexible containers, the packaging carts 5 install paper bags, and the carts 4 and 5 have the same structure. I do.
[0019]
As shown in FIG. 7, a load cell (or measuring instrument) connected to the support frame 20 is provided at the center of a rectangular support frame 20 erected on the vehicle body 19 and provided with a supply pipe 21 for powdery material. A flat plate-shaped support 23 suspended horizontally from the base 22 is provided. On this support 23, two or more hoists 24 such as pulleys are installed.
[0020]
The supply pipe 21 has a structure in which a central portion is expandable and contractible, and the upper part of the supply pipe 21 can be moved up and down around the expansion and contraction portion by a cylinder 25 installed above the support frame 20. The wheels 26 installed on the trolley 4 are rotated by a reversible motor 27 and can run on rails 28 laid on the ground. The flexible container bag A is installed in the support frame 20. The flexible container bag A, which has been inflated in advance, is connected to the hoisting machine 24 by an operator and is lifted above the cart 19, and the opening of the flexible container bag A is opened. And the lower part of the supply pipe 21 are connected.
When the package is a paper bag, the paper bag expanded in the packaging cart 5 may be connected to the hoisting machine 24 and lifted.
[0021]
The granular material supply unit 1 and the granular material packaging unit 2 have the above-described configuration. Next, a case where the granular material is filled and packaged in a package such as a flexible container bag A or a paper bag will be described.
As described above, the flexible container bag A and the paper bag are set by being lifted by the winding machine 24 on the packaging carts 4 and 5, respectively, and are waiting at predetermined positions shown in FIG. Further, each hopper 3 contains a powder having different content components, and stands by at the position shown in FIG. The standby position is the cleaning position of the hopper 3, and the hopper 3 is normally set at the cleaning position.
[0022]
For example, when a command to fill and package 300 kg of the powder stored in the first hopper 3a into the flexible container bag A is issued, the packaging cart 4 moves forward and the cart 6 on which the hopper 3a is placed also moves, and each of them moves at a specific point. Stop. The stop position of the packaging cart 4 and the cart 6 is an intersection a between the movement center line Y of the packaging cart 4 and the movement center line X of the cart 6.
[0023]
When the packaging cart 4 and the cart 6 stop around the intersection a, the supply pipe 21 is extended upward by the cylinder 25 and connected to the cut gate 8 below the hopper 3 (see FIG. 7). Thereafter, the cut gate 8 is opened to supply and fill the granular material into the flexible container bag A, and when the load cell 22 weighs and reaches a predetermined value, the cut gate 8 is closed to stop the supply of the granular material. Thereafter, the packaging cart 4 returns to the original position shown in FIG. 1, and the flexible container A may be removed from the hoisting machine 24 and carried out of the packaging cart 4 to the outside. Also, the carriage 6 is returned to the home position (washing position) after the supply of the granular material.
[0024]
As described above, the hopper 3 containing the granular material to be supplied may be selected, and the packaging cart 4 may be stopped at the intersection point a with the hopper 3 to supply the granular material at a predetermined value. The same applies to the case where the granular material is supplied to the flexible bag simultaneously or independently to the paper bag. For example, when the granular material of the hopper 3c is supplied to the paper bag, the packaging cart 5 and the hopper 3c May be stopped at a specific point. In addition, the specific stop position of the packaging cart 5 and the cart 6 is an intersection b between the X-ray and the Y-ray.
[0025]
A position detection sensor can be used to stop the packaging carts 4, 5 and 6 around the intersections a and b.
For example, two sensors are installed on both sides of the X-rays along the moving direction of the packaging carts 4 and 5 or on both sides close to the cut gate 8, and the sensors provided on the packaging carts 4 and 5 are moved in the traveling direction. The speed may be reduced when one sensor is detected, and stopped when the second sensor is detected. Similarly, in the case of the carriage 6, two sensors may be provided on both sides of the Y line, and the sensors installed on the carriage 6 may be stopped at a predetermined position by detecting the first and second sensors. .
[0026]
Since there are a plurality of hoppers 3, a sensor installed at the location of the hopper 3 to which the granular material is to be supplied may be operated to stop the packaging cart 4 below the selected hopper 3. Further, since the stop position of the cart 6 is the above-mentioned washing position, the filling position of the flexible container bag A, and the filling position of the paper bag, there are three positions, so that the sensor installed on both sides of the Y line and the sensor installed on the cart 6 Can be stopped at different heights.
[0027]
For example, as shown in FIG. 8, three sensors 29 are installed on the side surface of the trolley 6 at the top and bottom, and the sensors at the washing position 30, the flexible container bag filling position 31 and the paper bag filling position 32 have the upper, middle, lower and height. It should be different. The packaging carts 4, 5 and 6 may be stopped around the intersections a and b by using a known image processing device other than using the sensor. The means does not matter as long as it can be stopped at a predetermined position.
[0028]
Selection of necessary powder and granules, such as selection of hopper 3 having powder and granules to be supplied, start and stop of traveling of packaging carts 4 and 5 and cart 6, opening of cut gate 8 and automatic closing after measurement, etc. By managing all the operations of supplying by the computer, the operations can be performed reliably and stably. Although six hoppers 3 are shown in the figure, the number of hoppers 3 can be arbitrarily selected according to the content of the granular material.
[0029]
In the case of the flexible container bag A, a large amount of powder and granules is supplied and cannot be carried by an operator. For example, a pallet 33 is set on the vehicle body 19 and the flexible container A filled with the powder and granules is used. May be placed on a pallet 33, returned to a fixed position, and then carried out using a forklift. In the case of a paper bag, the operator can carry it out, but a forklift may be used to reduce the work load. The package filled with the predetermined amount of the granular material may be packaged in the packaging carts 4 and 5, or may be packaged by appropriate means after being carried out of the packaging carts 4 and 5.
[0030]
In the above description, the case where the granular material is supplied and packaged in the flexible container bag and the paper bag is described, but the present invention is not limited to this. Although not shown, another packaging trolley is allowed to reciprocate along a rail in parallel with the packaging trolley 5, and a metal or plastic container is placed on the body 19 of the packaging trolley via a measuring instrument. Alternatively, the powder and granules may be supplied from the hopper 3.
[0031]
Further, the packaging carts 4 and 5 show an example, and are not limited to the above-described configuration. In the packaging carts 4, 5, packages such as flexible container bags and paper bags are placed on a cart 19 via a scale, and the packages are stretched upward by a hoisting machine 24, and the cut gate 8 and the supply pipe 1 The powder and the granular material may be supplied and filled through.
[0032]
【The invention's effect】
