[Technical field to which the invention belongs]
The present invention relates to a method and apparatus for supplying and filling powders and granules (hereinafter collectively referred to as powders) made of various materials into a package such as a flexible container bag or a paper bag, and packaging. It is.
[0002]
[Prior art]
In a wide range of industrial fields such as foods, pharmaceuticals, and chemicals, granular materials made of various materials are used for product manufacture and product processing. And these granular materials are accommodated in packaging bodies, such as a flexible container bag and a paper bag, when shipping from a manufacturer. Moreover, the product manufacturer stores a mixture of powders having different contents in a predetermined amount and stores them in a package such as a flexible container bag or a paper bag in order to store or transport it to another place.
Usually, a flexible container bag is used to package a large amount of powder of 300 kg or more, and a paper bag is used to package a small amount of powder of 50 kg or less.
[0003]
Conventionally, a plurality of hoppers are used when a granular material is filled in a package such as a flexible container bag or a paper bag. For example, each hopper having an individual packaging machine contains powder particles with different contents, and the package is connected to the packaging machine of the hopper containing the required powder particles. The amount was filling. Alternatively, a plurality of hoppers containing powder particles having different content components and a single packaging machine are connected with a chute, and the packaging body is connected to the lower side of the packaging machine for filling. It 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 various types and small quantities of powder, so installing a wrapping machine for each hopper increases the capital investment. In addition, maintenance and inspection required a lot of time and personnel.
[0005]
In addition, when a plurality of hoppers and one packaging machine are connected by a chute, the hoppers are usually arranged in a horizontal row, so a chute between a plurality of hoppers located directly above the packaging machine is Since it is in a state close to vertical, it is possible to smoothly feed out the granular material. However, since the chute between the hoppers located away from the packaging machine has a gentle gradient, the flow of the powder particles is bad, causing a clogging phenomenon in the middle, and filling may not be possible.
[0006]
For this reason, in order to connect the hopper and the wrapping machine located away from the packaging machine with a steep chute, all the hoppers are installed at a high place, or at least the hopper located away from the packaging machine is installed. It must be installed at a high place and separated from the packaging machine by a large distance. As a result, the equipment for replenishing powder to each hopper becomes large, and the cleaning work when changing the product type is troublesome. Met.
[0007]
Furthermore, in the conventional filling device, for example, as shown in JP-A-7-33117, a pedestal is installed in an orthogonal state with respect to the filling unit, and an empty flexible container bag is sent from one pedestal to the filling unit, In order to carry out the flexible container bag filled with the granular material from the other frame, there was a problem that a large installation area was required.

Next, each part 1 and 2 will be described in detail.
As shown in FIG. 1, the powder supply unit 1 includes a hopper 3, a carriage 6 that reciprocates in the X direction with the hopper 3 mounted thereon, and a rectangular frame body 7 that supports the carriage 6 so as to be able to travel. ing.
As shown in FIGS. 2, 3, and 4, the hopper 3 having the cut gate 8 in the conical portion formed in the lower portion of the circular body portion is horizontally placed with four mounting plates 9 on the side surface of the body portion in an orthogonal state. Each mounting plate 9 is placed on a load cell 10 installed at the four corners of the carriage 6 and can be weighed.
[0015]
And the hopper 3 has connected with the trolley | bogie 6 and the mounting board 9 with the coupling tool 11 so that it may not 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 a single bolt 12, and the bolt 12 bends up and down 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 is for detecting the capacity of the granular material in the hopper 3 and is not necessarily required.
[0016]
The carriage 6 has a pair of wheels 13 before and after the traveling direction, and these wheels 13 are placed on rails 14 laid on the support frame 7. Then, as shown in FIG. 6, the sprocket 16 of the reversible motor 15 installed on the carriage 6 and the sprocket 18 of one axle 17 are connected by a chain, so that 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 drawing, it is sufficient that at least one wheel 13 is fitted to the rail 14 and rotates, and the other wheel 13 only needs to be placed on the rail 14.
[0017]
In the packaging carts 4 and 5 described above, for example, the packaging cart 4 has a flexible container bag, the packaging cart 5 has a paper bag, and the carts 4 and 5 have the same structure. To do.
[0018]
As shown in FIG. 7, a powder cell supply pipe 21 is provided at the center of a rectangular support frame 20 erected on the vehicle body 19, and a load cell (or measuring instrument) connected to the support frame 20. A flat plate-like support body 23 suspended horizontally through 22 is provided. On this support body 23, two or more hoisting machines 24 such as pulleys are installed.
[0019]
The supply pipe 21 has a structure in which the central portion can be expanded and contracted, and the upper portion of the supply pipe 21 can be moved up and down around the expansion and contraction portion by a cylinder 25 installed on the upper portion of the support frame 20. Further, the wheels 26 installed on the packaging cart 4 are rotated by a motor 27 that can be reversed, and can run on rails 28 laid on the ground. The flexible container bag A is installed in the support frame 20, and the flexible container bag A that has been inflated in advance is connected to the hoisting machine 24 by the upper part and lifted above the carriage 19 and the mouth of the flexible container bag A. 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.
[0020]
The granular material supply unit 1 and the granular material packaging unit 2 are configured as described above. Next, a case where the granular material is filled and packaged in a packaging body 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 on the packaging carts 4 and 5 by being lifted by the hoisting machine 24, and are waiting at the predetermined positions shown in FIG. In addition, each hopper 3 contains powder particles having different content components, and stands by at the position shown in FIG. The standby position is a cleaning position for the hopper 3, and the hopper 3 is normally placed at the cleaning position.
[0021]
For example, when an instruction to fill and package 300 kg of powder contained in the first hopper 3a in the flexible container bag A is given, the packaging cart 4 moves forward and the cart 6 carrying the hopper 3a also moves. 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.
[0022]
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 powder container 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 supplying the powder. Thereafter, the packaging cart 4 returns to the original position shown in FIG. 1, and the flexible container bag A is removed from the hoisting machine 24 and carried out of the packaging cart 4 to the outside. Further, the carriage 6 is also returned to a fixed position (cleaning position) after the supply of the granular material.
[0023]
The hopper 3 containing the granular material to be supplied as described above is selected, and the packaging cart 4 is stopped at the intersection point a with the hopper 3 to supply a predetermined value of the granular material. The same applies when supplying the granular material to the flexible bag simultaneously or independently to the paper bag. For example, when supplying the granular material of the hopper 3c to the paper bag, the packaging cart 5 and the hopper 3c What is necessary is just to stop the trolley | bogie 6 which has this 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.
[0024]
A position detection sensor can be used to stop the packaging carts 4 and 5 and the cart 6 around the intersections a and b.
For example, two sensors are installed on both sides of the X-ray along the moving direction of the packaging carts 4 and 5 or on both sides in the vicinity of the cut gate 8, and the sensors provided on the packaging carts 4 and 5 are arranged in the direction of travel. The speed should be slowed down when one sensor is detected and stopped when the second sensor is detected. Similarly, in the case of the cart 6, two sensors may be provided on both sides of the Y line, and the sensor installed on the cart 6 may be stopped at a predetermined position by detecting the first and second sensors. .
[0025]
In addition, since there are a plurality of hoppers 3, it is only necessary to operate a sensor installed at the location of the hopper 3 to which the powder particles are supplied to stop the packaging cart 4 below the selected hopper 3. Further, since the carriage 6 has three stop positions, the washing position, the filling position in the flexible container bag A, and the filling position in the paper bag, the sensor installed on both sides of the Y line and the sensor installed on the carriage 6 Can be stopped at different heights.
[0026]
For example, as shown in FIG. 8, three sensors 29 are installed vertically on the side of the carriage 6, and the sensors at the cleaning position 30, the flexible container bag filling position 31 and the paper bag filling position 32 have an upper, middle, and lower height. You can make it different. In addition to using a sensor, the packaging carts 4 and 5 and the cart 6 may be stopped around the intersections a and b by using a known image processing apparatus, and the packaging carts 4 and 5 and the cart 6 may be stopped. The means is not questioned as long as it can stop at a predetermined position.
[0027]
Selection of necessary powders such as selection of hopper 3 having powders to be supplied, start and stop of packaging carts 4, 5 and cart 6, opening of cut gate 8 and automatic closing after weighing By managing all the operations for supplying the information by a computer, the operations can be performed reliably and stably. In the figure, six hoppers 3 are shown, but the number of hoppers 3 can be arbitrarily selected according to the content of the granular material.
[0028]
In the case of the flexible container bag A, a large amount of powder particles are supplied and cannot be carried by the operator. For example, the flexible container bag A in which the pallet 33 is set on the vehicle body 19 and filled with the powder particles. May be placed on the pallet 33 and returned to a fixed position, and then carried out using a forklift. In the case of a paper bag, the worker can carry it out, but a forklift may be used to reduce the work load. The package filled with a predetermined amount of powder particles 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.
[0029]
In the above description, the granular material is supplied to the flexible container bag and the paper bag and packaged, but the present invention is not limited to this. Although not shown in the figure, the other packaging cart can be reciprocated along the rail in parallel with the packaging cart 5, and a metal or plastic container is placed on the car body 19 via a measuring instrument. You may make it place and supply a granular material from the hopper 3. FIG.
[0030]
Moreover, the packaging carts 4 and 5 show an example, and are not limited to the above-described configuration. In the packaging carts 4 and 5, packaging bodies such as flexible containers and paper bags are placed on the cart 19 via a measuring instrument, and the packaging body is stretched upward by a hoisting machine 24, and the cut gate 8 and the supply pipe 1. You may make it supply and fill a granular material through.
[0031]
【The invention's effect】
As described above, according to the present invention, a plurality of trolleys provided with hoppers containing powder particles are installed on a support frame constructed at a predetermined spatial position, and each hopper has different content components. Since each trolley can move back and forth in a certain direction and can be stopped at a specific position, a packaging body such as a flexible container bag or a paper bag is placed below the hopper stop position. Thus, the selected hopper powder can be supplied to the package and packaged.
[0032]
In particular, flexible packaging bags, paper bags, and other packagings are installed in a movable packaging cart so that they can be weighed, and the packaging cart is stopped below the stop position of the hopper so that a predetermined amount of powder particles can be placed on the packaging. The body can be supplied, and then the packaging cart can be moved elsewhere to perform the packaging process.
[0033]
According to the present invention, in addition to flexible containers and paper bags, it is possible to supply and package the necessary amount of powder and granular materials necessary for various types of packaging bodies made of metal, plastic, and the like. Etc. can be carried out automatically and continuously, so that no contamination occurs and a stable processing operation is possible.
