Description

The present invention relates to a distribution metering device, and in particular, a granular raw material that is continuously supplied, for example, kaki for instant noodles, is cut intermittently, and all of this is divided into a predetermined amount of the granular raw material. Instead of weighing, supply to the weighing means only once every several times, and measure only before feeding to the next process. The present invention relates to an apportioning and metering device that adjusts the amount and supplies the granular raw material continuously and intermittently to a predetermined amount to the next packaging step or the like.

Conventionally, in an automatic packaging machine that automatically fills and wraps irregular shaped raw materials such as instant foods and plant seeds, as described in Patent Document 1, a hopper is provided prior to supply to an automatic packaging machine. The granular raw material stored in is continuously discharged from the rotating pipe inclined downward in the same direction through the discharge part of the hopper to the measuring means, and after a predetermined amount is always measured by the measuring means. It is configured to be intermittently supplied to the automatic packaging machine. As a result, it is possible to cut out a predetermined amount that has been accurately measured, and to automatically package a predetermined amount of granular material. Further, in the conventional patent document 2, a rotating pipe is not used, but a peristaltic cylinder corresponding to this is used. Similarly, after a predetermined amount of the granular raw material is always measured by the measuring means, the intermittent pipe is intermittently used. In the same way, it is configured to be supplied to an automatic packaging machine, and similarly, it is possible to cut a predetermined amount that has been measured accurately and to automatically package a predetermined amount of granular material.

However, in both Patent Documents 1 and 2, there is a problem that it takes time to measure the granular raw material by the measuring means. That is, the measurement itself can be performed instantaneously, but for example, even if the granular raw material is supplied into the bucket, the measurement of the granular raw material in the bucket is started until the granular raw material is stabilized until the granular raw material is stabilized. In addition, the granular raw material cannot be supplied into the bucket until the open / close shutter is closed after the measured granular raw material is completely discharged from the open / close shutter of the bucket. As described above, when it takes time to measure the weighing means, the realization of high-speed processing by the automatic packaging machine has a limit based on the weighing time.

Therefore, as described in Patent Document 2, conventionally, a plurality of measuring buckets are provided, and granular raw materials are supplied by branching to each, and the granular raw materials sequentially measured from the respective measuring buckets are processed at a predetermined timing. The current situation is that it can be discharged quickly and is compatible with high-speed processing by automatic packaging machines.

Japanese Patent Laid-Open No. 08-226845 JP 2014-114149 A

However, as described above, providing a plurality of buckets, and thus a plurality of weighing machines, also involves a large number of auxiliary devices and control devices. For example, a continuous and intermittent supply device for granular raw materials to an automatic packaging machine is provided. There has been a problem that the cost is increased due to the increase in size and complexity.

As a result of intensive research to solve the above-mentioned problems, the present inventor has always measured amorphous powdery raw materials such as instant foods and plant seeds as usual. Inevitably accompanied by a weighing error, and the loss of the weighing time as described above is not eliminated by providing a plurality of weighing machines, and this loss time can be absorbed even with a single weighing machine, The present inventors have found that it is possible to quickly supply a granular raw material to the next process such as a packaging process, and have reached the present invention based on this knowledge.

Accordingly, an object of the present invention is to provide a novel distribution metering apparatus that solves the above-mentioned problems.

The present invention firstly provides an apportioning and metering apparatus according to claim 1 that solves the above-mentioned problems. The applicator and metering apparatus of the present invention intermittently supplies granular raw materials at a predetermined timing. Temporary holding bucket means for discharging to a subsequent process, a metering path and a non-metering path for deriving the granular raw material to the temporary holding bucket means, and the continuously supplied granular raw material are intermittently supplied once to the measuring path at a predetermined timing. After the distribution, the distribution is intermittently performed a plurality of times on the non-metering path, the distribution means is configured to repeat this cycle continuously, the granular raw material distributed in the measurement path is weighed, and the measured granularity The weighing means for discharging the raw material to the temporary holding bucket means at the timing before the distribution to the weighing path in the next cycle, and the weight of the granular raw material measured by the weighing means Flip and characterized in that it consists of a supply amount control means for adjusting a continuous supply of particulate material to said distributing means.

Further, the present invention provides a distribution metering supply device according to claim 2 in which the above-mentioned problems are solved. In the distribution metering supply device of the present invention, the distribution means is arranged around a horizontal axis bar. An impeller provided with a plurality of blades radially spaced at equal intervals, the impeller intermittently rotated once around the horizontal water shaft rod at regular intervals, and then reversely rotated a plurality of times. The granular raw material continuously supplied between the adjacent blades is distributed to the measurement path during the forward rotation, and is distributed to the non-measurement path during the reverse rotation.

In the present invention, the sorting means is not limited to a simple, mechanically stable and inexpensive mechanism as described above. Specifically, for example, it is possible to adopt a configuration in which the granular raw material that is continuously supplied is distributed to the non-measurement path and the measurement path only by an open / close shutter or the like.

The distribution metering and supply apparatus of the present invention intermittently cuts the granular raw material that is continuously supplied, for example, kaki for instant noodles, and does not measure all of this for every fixed amount of granular raw material that has been cut. Rather than using the time during which the granular raw material that has been distributed to the weighing process and divided without weighing is supplied to the next process, only this is measured before being supplied to the next process. Therefore, based on this measurement, the supply amount of the granular raw material to be continuously supplied is adjusted, and thus the granular raw material can be continuously and intermittently supplied to a predetermined amount to the next packaging step or the like. There is. Therefore, according to the distribution metering supply apparatus of the present invention, the continuous and intermittent use of the granular raw material to the automatic packaging machine, for example, despite using a single weighing means and a single temporary holding bucket. As a supply device, there is an effect that the device can be reduced in cost without increasing in size and complexity.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1, 2, and 3, 1 is a temporary holding bucket means for intermittently discharging the granular raw material 2 to a subsequent process at a predetermined timing, and 3 and 4 are respectively deriving the granular raw material 2 to the temporary holding bucket means 1. A weighing path and a non-metering path. 5, the continuously supplied granular raw material 2 is intermittently distributed once to the measurement path 3 at a predetermined timing and then intermittently distributed to the non-measurement path 4 a plurality of times, and this distribution is defined as one cycle. It is a sorting means that repeats continuously. 6 measures the granular raw material 2 distributed in the measuring path 3, and discharges the measured granular raw material 2 to the temporary holding bucket means 1 at a timing before distribution to the measuring path 3 in the next cycle. It is a measuring means. Reference numeral 7 denotes supply amount control means for adjusting the continuous supply amount of the granular raw material 2 to the distribution means 5 according to the weight of the granular raw material 2 measured by the measuring means 6.

The embodiment will be described in further detail. In this embodiment, the continuous supply of the granular raw material 2 from the hopper 20 to the distribution metering supply device is rotatably connected to the lower portion of the hopper 20 and inclined together with the hopper 20. The granular raw material 2 is continuously supplied from the front end portion of the rotary pipe 21 to the distribution means 5 through the intake bucket 22 from the front end portion of the rotary pipe 21 whose angle can be adjusted. In this embodiment, the continuous supply amount of the granular material 2 is performed by adjusting the rotation amount of the rotary pipe 21. This adjustment is performed by controlling the drive unit 23 of the rotary pipe 21 by the supply amount control means 7. In addition, a flexible member such as a polytetrafluoroethylene plate may be provided in the long hole 24 at the bottom of the intake bucket 22 so that the granular raw material 2 can be smoothly supplied to the distribution metering device. preferable.

The distribution means 5 includes an impeller 52 in which four blades 51a, 51b, 51c, 51d are provided radially at equal intervals around a horizontal axis rod 50. The impeller 52 intermittently rotates once around the horizontal water shaft rod 50 at regular intervals (in the illustrated case, once in the right direction) and then reversely rotates three times (in the illustrated case, 3 times). A predetermined amount of granular raw material 2 that is continuously supplied between adjacent blades 51a and 51b, etc., is distributed to the metering path 3 during the forward rotation and the non-metering path 4 during the reverse rotation. So that it is controlled and driven. In the case of this embodiment, the intermittent left and right pivoting of the impeller 52 is performed so that the impeller 52 pivots rapidly around 180 degrees within the horizontal water shaft rod 50 and then immediately reverses to a position rotated 90 degrees. Controlled and driven. As for the left and right rotation, a 90-degree rotation is sufficient, but once it exceeds 90 degrees as in this embodiment, a predetermined amount of granular raw material 2 is distributed to the measurement path 3 and the non-measurement path 4. The operation can be performed reliably and quickly. Such intermittent turning to the left and right is controlled and driven so as to be performed at the same timing at a slightly earlier phase than the discharge to the intermittent subsequent process at a predetermined timing by the temporary holding bucket means 1. Yes. Except for such intermittent left-right rotation, the upper two blades 51a, 51b are opened symmetrically with respect to the continuously supplied granular raw material 2 as shown in FIG. Is in a state. In the description of the operation described later, this state is said that the impeller 52 is in a fixed position.

In the embodiment, the impeller 52 of the distribution means 5 is accommodated in a drum 53 having a skirt portion 54 at the lower part. Both side surfaces of each blade 51a, 51b, 51c, 51d of the impeller 52 are close to the inner surface of the drum 53, so that the granular raw material does not escape from both sides of each blade 51a, 51b, 51c, 51d. Yes. The long hole 24 at the bottom of the intake bucket 22 is provided at the top of the drum 53 in parallel with the horizontal water shaft rod 50, and the inner space on the left side of the drum 53 and its skirt 54 is the measuring path 3. In addition, the right internal space is configured as the non-metering path 4. The temporary holding bucket means 1 is located below the skirt portion 54, and the measuring means 6 is located in the measuring path 3. A partition wall may be provided between the weighing path 3 and the non-metering path 4 as necessary.

The temporary holding bucket means 1 temporarily holds the granular raw material 2 from the metering path 3 and the non-metering path 4, and an open / close shutter 11 is provided in the lower part thereof. This open / close shutter 11 is normally closed, temporarily holds a predetermined amount of the granular raw material 2 that falls through the measurement path 3 or the non-measurement path 4, opens at a predetermined timing, and for the processing of the next process, Control and drive so that a predetermined amount of granular raw material 2 held in a temporary holding bucket can be discharged to a container 81 such as a packaging container or a packaging bag that is sent at equal intervals on a conveying device 8 such as a conveyor. Has been.

The weighing means 6 is composed of a bucket body 62 having an open / close shutter 61 and a weight meter (not shown) such as a load cell that supports the same as the temporary holding bucket means 1. The weight of the granular raw material 2 supplied to the pipe is weighed by this weight meter, converted into an electric signal, and the drive unit 23 of the rotary pipe 21 is controlled by the supply amount control means 7 so that the rotation speed of the rotary pipe 21 is adjusted. Thus, the continuous supply amount per unit time of the granular raw material from the rotary pipe 21 to the distribution means 5 is adjusted. The opening / closing shutter 61 is driven and controlled as follows. That is, the opening / closing shutter 61 is normally closed so that the measuring time of the granular raw material 2 in the bucket body 62 can be made long. The opening / closing shutter 61 is opened immediately before being supplied to the granular raw material 2 in the bucket main body 62 by the sorting means 5, and when the opening / closing shutter 61 is opened, a predetermined amount of the granular raw material 2 in the bucket main body 62 is It is discharged into the temporary holding bucket means 1. The opened opening / closing shutter 61 is closed immediately after discharging the granular raw material 2 to prepare for the measurement of the granular raw material supplied by the sorting means 5. In the temporary holding bucket means 1, when the granular raw material 2 is discharged from the opening / closing shutter 61, the granular raw material 2 already supplied via the non-metering path 4 has been discharged to the next process and is empty, and the temporary holding bucket means The granular raw material 2 discharged in 1 as described above is prepared for discharge from the temporary holding bucket means 1 to the next process.

Next, the operation of the above-described embodiment will be described with reference to FIGS.

FIG. 4 shows a state in which the impellers 51a and 51b serving as the distributing means 5 are at fixed positions and the rotation to the left and right is stopped. In this state, the granular raw material 2 is continuously supplied from the rotating pipe 21 between the blades 51a and 51b located above, and the granular raw material 2 is gradually accumulated between the blades 51a and 51b.

As shown in FIG. 4, after a certain time t from when the blades 51a and 51b are stopped at the fixed positions, the impeller 52 rotates rightward in the range of over 90 degrees to 180 degrees, and immediately turns left to position. The state shown in FIG. 5 is rotated 90 degrees to the right from the state before the rotation. At this time, the granular raw material 2 falls in the measuring path 3 and is supplied and accumulated in the measuring means 6. The granular raw material 2 accumulated in the measuring means 6 is measured after being stabilized, and based on this measurement, the rotational speed of the rotary pipe 21 is controlled by the control means 7 as described above. Supply amount is adjusted. On the other hand, when the impeller 52 rotates to the right as shown in FIG. 5 and stops, the blades 51b and 51d stop at a fixed position, and the granular raw material 2 is continuously supplied from the rotary pipe 21 between the blades 51b and 51d. .

As shown in FIG. 5, the granular raw material 2 is continuously supplied between the blades 51a and 51b after a predetermined time t after the blades 51a and 51b are stopped at the fixed positions, and a certain amount of the granular raw material 2 is formed as shown in FIG. When accumulated, the impeller 52 does not rotate right but rotates counterclockwise in the range of more than 90 degrees and up to 180 degrees, immediately turns right, and is positioned 90 degrees left from the position before rotation. It will be in the state of FIG. 7 which rotated. At this time, the granular raw material 2 falls in the non-metering path 3, is directly supplied into the temporary holding bucket means 1, and is accumulated as shown in FIG. As shown in FIG. 9, the granular raw material 2 accumulated in the temporary holding bucket means 1 moves intermittently to a subsequent process at a predetermined timing because the opening / closing shutter 11 of the temporary holding bucket means 1 opens immediately after that. It is supplied into the container 81. The opening / closing shutter 11 is immediately closed as shown in FIG. 10 after discharging the granular raw material 2, and prepares for the supply of the granular raw material 2 into the temporary holding bucket means 1. In FIG. 1, the granular raw material 2 is still accumulated in the measuring means 6. If the granular raw material 2 in the measuring means 6 is stable, the measurement is made. Based on this measurement, the rotation amount of the rotary pipe 21 is adjusted as described above, and the supply amount of the granular raw material from the rotary pipe 21 is adjusted. Thus, a predetermined amount of the granular raw material 2 is continuously supplied.

In the state of FIG. 10 described above, the blades 51a and 51b are positioned at the fixed positions, and after a predetermined time t from when they are positioned at the fixed positions, a predetermined amount of the granular raw material 2 is supplied between them. 52 starts to turn left. This state is the same as the state shown in FIG. 6, and thereafter, similarly to the case described above, the state shown in FIG. 10 is obtained again through FIGS. 7, 8, and 9. At this time, although not shown, the blades 51b and 51c are located at fixed positions.

Further, in this embodiment, after a certain time t when the blades 51b and 51c are positioned at the fixed positions, the impeller 52 starts the third left turn from the state of FIG. 8 and 9 again, the state shown in FIG. 10 is obtained again. At this time, as shown in FIG. 11, the blades 51c and 51d are located at the fixed positions. Before the elapse of a fixed time t during which a fixed amount of granular raw material 2 is supplied between the blades 51c and 51d, the open / close shutter 61 of the measuring means 6 which has been closed so far is opened as shown in FIG. The raw material 2 is discharged into the temporary holding bucket means 1 via the metering path 3. When this discharge is completed, the open / close shutter 61 is closed to prepare for the supply of the granular raw material to the next measuring means 6. At this time, the granular raw material 2 in the temporary holding bucket means 1 supplied to the temporary holding bucket means 1 at the time of the third rotation to the left is already discharged in a subsequent process, and the temporary holding bucket means 1 is opened and closed. The shutter 11 is closed. Therefore, the granular raw material 2 discharged into the temporary holding bucket means 1 is temporarily stored in the temporary holding bucket means 1 as shown in FIG. 12, and is discharged to a subsequent process at a predetermined timing by opening the opening / closing shutter 11 at a predetermined timing. The

On the other hand, after a predetermined time t after the blades 51c and 51d are positioned at the fixed positions, the impeller 52 starts to rotate right as shown in FIG. 12, and as already described, as shown in FIG. Thus, the granular raw material 2 is dropped and supplied into the measuring means 6 and accumulated in the measuring means as shown in FIG. At this time, as described above, since the granular raw material 2 accumulated in the previous weighing means 6 is completely discharged, the granular raw material 2 supplied last time and this time is not mixed.

In this way, in this embodiment, the impeller 52 performs a right turn once and a left turn intermittently every fixed time t, and this left and right turn is defined as one cycle. It is controlled and driven to repeat the cycle continuously. Then, the granular raw material 2 that has been divided, distributed, and supplied into the weighing means 6 by turning right in a certain cycle is temporarily separated before the granular raw material 2 is divided, distributed, and supplied into the measuring means 6 of the next cycle. It is discharged to the holding bucket means 1. Accordingly, the granular raw material 2 in the measuring means 6 is weighed for a total of approximately 4 t hours before the elapse of the fixed time t from the time 3 t when the impeller 52 rotates three times to the left until the start of the right rotation. The granular raw material 2 is weighed by selecting an arbitrary time when the granular raw material 2 is considered to be stable within the time 4t, and the granular raw material 2 from the rotary pipe 21 is based on this measurement as described above. Is continuously adjusted to a desired amount. Furthermore, the supply of the granular raw material 2 is substantially the same whether the temporary holding bucket means 1 is supplied from the measuring means 6 via the measuring path 3 or directly supplied via the non-metering path 4. It is performed at the timing, and is discharged and supplied from the temporary holding bucket means 1 smoothly and intermittently to the subsequent process. Further, as the open / close shutters 11 and 61, any ones such as a rotary type and a slide type can be used.

In the present embodiment, the left rotation of the impeller 52 in one cycle is three times. However, in the present invention, a plurality of times is sufficient. Four blades 51a, 51b, 51c, 51d are used, but two or more blades are sufficient.

FIG. 15 shows a main part of another embodiment of the present invention, in which a sorting bucket 55 is used as the sorting means 5 in place of the impeller 52. The sorting bucket 55 is provided with opening and closing shutters 56 and 57 at the left and right lower parts, respectively, and the right opening and closing shutter 57 is intermittently opened once in response to the use of the impeller 52, and then the left and right opening and closing shutters are opened. The shutter 56 is intermittently opened three times, and this is set as one cycle, and this cycle is continuously repeated. Therefore, it is obvious that the same operation and effect as those of the previous embodiment can be obtained by the distribution supply device of the present invention according to this embodiment.
