Description

  The present invention relates to a combination alignment system.

In recent years, as foods such as stick-shaped snacks, a product in which a large number of sticks are filled in a cylindrical container in a vertical posture has been sold. It is important to align the rods because the rods have different filling efficiencies depending on the alignment. That is, by improving the alignment state, it becomes possible to fill a small container with many sticks.
Therefore, an alignment device for aligning rod-like objects has been proposed (see Patent Document 1).

JP2001-213409 (FIG. 3)

  As shown in FIG. 6, the alignment apparatus of Patent Document 1 repeatedly vibrates the alignment chamber 100 in a direction including a horizontal component to swing the rod-like object M in the horizontal direction, then opens the shutter 101, and The rod-like object M is dropped downward.

However, when the soft rod-shaped object M or the like is repeatedly swung, the rod-shaped objects M may cross each other, and a part of the rod-shaped objects M may not be aligned while protruding upward. Further, as the swinging is repeated, the tip of the rod-like object M may be bent and cannot be aligned.
On the other hand, it has been proposed to provide a partition 102 that divides the inside of the alignment chamber 100 in the vertical direction Z and to drop the rod-like objects M into the alignment chamber 100 in an aligned state. However, when the rod-shaped object hits the upper end of the partition 102, a problem such as the rod-shaped object M being clogged above the partition 102 occurs.

  Accordingly, an object of the present invention is to provide an alignment apparatus and method that can improve the filling efficiency of the containers by improving the alignment state of the rod-shaped objects.

In order to solve the above problems, the combination alignment system of the present invention obtains the optimum combination of hoppers by combining the weights of the rod-like objects supplied to a plurality of hoppers, and drops the rod-like objects from the obtained optimum combination of hoppers. A combination alignment system comprising a combination weighing device for discharging and an alignment device for aligning the dropped and discharged rod-like objects in a vertical posture, wherein the alignment device is formed by an upper tube portion and a shutter below the upper tube portion. A swinging means for swinging the rod-shaped object in a direction including a horizontal component by swinging the entire upper cylinder portion together with the upper alignment chamber and the rod-shaped object accommodated in the upper alignment chamber. And projecting upward on the upper surface of the shutter and extending in the forward / backward direction of the shutter, when the rod-shaped object from the combination weighing device falls on the shutter. Partition portion is provided on the end portion is prevented from stick-shaped material engaging falls down, it is arranged close to articulation to the bottom of the upper alignment chamber, the lower alignment chamber formed by the lower tubular part and receiving part The lower cylinder part is movable relative to the receiving part in the horizontal direction .

According to the present invention, when the rod-shaped object falls into the upper alignment chamber, the lower end of the rod-shaped object engages with the partition portion, so that the rod-shaped object is unlikely to fall down in the upper alignment chamber. In addition, since there is no vertical partition that divides the alignment chamber in the vertical direction, problems such as sticking of rod-like objects do not occur at the upper end of the vertical partition. Therefore, the efficiency of filling the container is improved by improving the alignment state of the rod-like objects. Further, a further alignment effect can be expected from the lower alignment chamber.

FIG. 5 is a schematic front view and a schematic side view showing the operation of the alignment apparatus. FIG. 6 is a schematic perspective view showing a conventional alignment apparatus. FIG. 7 is a flowchart showing another operation method of the combination weighing device.

In the present invention, it is preferable that the upper cylinder part is formed with a slit through which the upper partition part passes when the shutter advances and retreats along the lower end of the upper cylinder part.
By forming the thin slit, it becomes difficult for the broken pieces of the rod-shaped object to fall from the slit, so that the apparatus can be kept clean.

In the present invention, the lower partition that protrudes downward on the lower surface of the shutter, extends in the forward / backward direction of the shutter, and can kick the upper end of the rod-shaped object that protrudes upward from the aligned rod-shaped object in the lower alignment chamber. It is preferable that a portion is further provided.
According to this aspect, since the bar-like objects protruding upward in the lower alignment chamber are pushed in by the lower partition portion when the shutter advances and retreats, overlapping of the bar-like objects in the lower alignment chamber can be suppressed.

In the present invention, a plurality of lower tube portions of the lower alignment chamber are provided, and the plurality of lower tube portions are a first position below the upper tube portion and a second position beside the first position. The rod-shaped object in the lower alignment chamber may be dropped downward at the second position.
According to this aspect, one lower cylinder part moves horizontally and drops the rod-like object at the second position, and the rod-like object immediately falls after the movement to the other lower cylinder part moved to the first position. Can be made.

It is set to be able to move alternately with the second position P2.
The lower alignment chamber 20 is closed at its lower end by a fixed bottom 15 at the first position P1. On the other hand, the lower alignment chamber 20 has its lower end positioned on the receiving portion 12 at the second position P2.

Method for aligning rods M:
The combination weighing device 400 shown in FIG. 1 combines the weights of the rod-like objects M to bring the rod-like objects M together to a target value or a value close to the target value. The rod-like object M is dropped into the upper alignment chamber 10 of the alignment apparatus 200. At this time, as shown in FIGS. 4A and 4B, the shutter 2 is set in a closed state.

The rod-like objects M discharged from the collective discharge chute 9 are dropped into the upper alignment chamber 10.
When the rod-shaped object M falls into the upper alignment chamber 10, the lower end of the rod-shaped object M engages with the upper partition 2 u of the shutter 2, and the rod-shaped object M is unlikely to fall within the upper alignment chamber 10. After the rod-like objects M fall into the upper alignment chamber 10, the posture of the rod-like objects M is changed by the rocking means 40 repeatedly rocking (vibrating) in the horizontal direction H at a predetermined timing. It approaches a vertical posture.

Thereafter, as shown in FIG. 4C, when the shutter 2 is opened, as shown in FIGS. 5A and 5B, the rod-like objects M are placed in the lower alignment chamber 20 in the first position P1. Fall into. Note that the lower end portion of the lower alignment chamber 20 is closed by the fixed bottom 15.
After the fall, as shown in FIG. 5C, the shutter 2 is moved in the closing direction, so that the rod-like object M having two upper and lower stages in the lower alignment chamber 20 becomes the lower partition of the shutter 2. The portion 2d is pushed into the lower alignment chamber 20, and the overlap in the lower alignment chamber 20 is suppressed.

Thereafter, the lower alignment chamber 20 including one first lower cylinder portion 21A shown in FIG. 2A is moved from the first position P1 to the second bottom shown in FIG. It is moved to position P2. By this movement, the lower alignment chamber 20 including the other second lower cylindrical portion 21B is moved to the first position P1 directly below the upper alignment chamber 10.
After the movement, the rod-like object M in the lower alignment chamber 20 composed of the first lower cylinder portion 21A is discharged from the discharge port 14 through the chute 13 when the receiving portion 12 is opened.
After the discharge, the receiving part 12 is closed.

On the other hand, as shown in FIGS. 4A to 4C, after the next rod-like object M is introduced into the upper alignment chamber 10, the next new rod-like object M is shown in FIG. 5A and FIG. As shown in FIG. 5 (b), it is introduced into the other second lower cylinder portion 21B.
Thereafter, the lower alignment chamber 20 composed of the second lower cylinder portion 21B is moved from the first position P1 shown in FIG. 3 to the second position P2 shown in FIG. The lower alignment chamber 20 including the first lower cylinder portion 21A is positioned at the first position P1.
After the movement, the rod-like object M in the lower alignment chamber 20 composed of the second lower cylinder part 21B is discharged from the discharge port 14 through the chute 13 when the receiving part 12 is opened.
After the discharge, the receiving part 12 is closed.

  Thus, a pair of the lower cylinder portions 21A, 21B of the lower alignment chamber 20 is provided, and the plurality of lower cylinder portions 21A, 21B are disposed at the first position P1 below the upper cylinder portion 11, and the first The second position P2 next to the first position P1 is moved alternately in conjunction with each other. Therefore, after one lower cylinder part 21A (21B) moves in the horizontal direction H and drops the rod-like object M at the second position P2, the other lower cylinder part 21B (21A) moved to the first position P1. ) Can immediately drop the rod-like object M.

As described above, the preferred embodiments have been described with reference to the drawings. However, those skilled in the art will readily understand various changes and modifications within the obvious scope by looking at the present specification.
For example, the number of lower alignment chambers may be one, or three or more.
Further, as shown in FIGS. 5B and 5C, when the shutter 2 moves in the closing direction, the lower cylinder portions 21A and 21B may be swung (vibrated).

Note that the following functions may be added to devices such as the combination weighing device 400 and the alignment device 200.
In the combination weighing device 400 shown in FIG. 1, when it is determined that the supply amount of the rod-like object M is insufficient in the weighing hopper body 6i, the supply amount of the rod-like object M to each pool hopper body 4i is an appropriate value. It is increased until it becomes. In order to increase the supply amount of the rod-like object M, the dispersion weight of the rod-like object M, the amplitude intensity, the amplitude time, the amplitude intensity and time of the supply trough 3i, and the like are controlled based on past calculation results.

By the way, the rod-like object M supplied from the dispersion feeder 401 onto the supply trough 3i has a bridge (for example, when the rod-like objects M are neatly stacked) due to the influence of the shape of the rod-like object M, the shape of the dispersion feeder 401, or the like. May occur. When such a bridge occurs, it is determined that the supply is poor, and the dispersion weight of the rod-like object M, which has maintained a good operating rate, and the amplitude intensity and time of the dispersion feeder 401 and the supply trough 3i are changed to appropriate values. Control is performed.
However, when the control is performed, there is a possibility that the supply balance of the objects to be weighed M to the weighing hopper main bodies 6i may be lost.
Further, depending on the control, since there is no change in the dispersion weight of the rod-like object M, when no additional supply from the dispersion feeder 401 is performed, all the rod-like objects M on the supply trough 3i are also thrown into the pool hopper body 4i. After that, it becomes light (so-called idle) and the operating rate is lowered.

  Therefore, the combination weighing device 400 temporarily (for example, when a certain condition is reached from the relationship between the change in the supply amount of each pool hopper body 4i and the weight change of the pool hopper body 4i) (for example, The amplitude intensity is increased (during several cycles) and set back to the previous state again. By such control, the bridge state of the rod-like object M can be avoided.

Such control will be described with reference to the flowchart of FIG.
When the operation of the combination weighing device 400 is started, in step S1, the amount of the rod-like object M input to each supply trough 3i is reduced, and the supply shortage state of the rod-like object M (a state where no rod-like object M is supplied) continues for several cycles. If the dispersion weight is almost unchanged, the process proceeds to step S2. In step S2, there is a rod-like object M on the dispersion feeder 401, but since it is bridged, it is determined that this state is not disrupted with normal amplitude and supply to the supply trough 3i is not possible. Proceed to step S3. In step S3, the amplitude of the dispersion feeder 401 is increased for several cycles, and then returned to the original amplitude.
As a result, the bridge state is destroyed, and the supply of the rod-like object M from the dispersion feeder 401 to the supply trough 3i is started again.

  On the other hand, if it is determined in step S1 that there is no change in the dispersion weight, the process proceeds to step S4. In step S4, it is determined that the normal operation state is maintained, and the process proceeds to step S5 which is the conventional control. In step S5, the AFD control (automatic control) of the dispersion feeder 401 is continued.

  Therefore, in the conventional control, when the amplitude intensity / time and the dispersion weight of the supply trough 3i and the dispersion feeder 401 are changed, it takes several cycles to return to the original optimum value. On the other hand, according to this control, when the bridging of the rod-like object M is eliminated, the value immediately before the rod-like object M bridges is restored, so that the operating rate can be quickly restored to a stable state. Thereby, the number of defects such as light weight and overscale of the rod-like object M can be reduced.

  Incidentally, in the combination weighing device 400 shown in FIG. 1, a supply trough (dispersion feeder) 3i is arranged for the purpose of distributing the supplied objects M to be supplied to each pool hopper body 4i. The feed amount (feeder feed force) of the object M to be fed by each of these supply troughs 3i is stored in the storage device. When the combination weighing device 400 is operated, the feeder feeding force is adjusted each time manually or automatically by the operator according to the operation state of the combination weighing device 400, and is sequentially updated and stored in the storage device.

When the combination weighing device 400 is operated in order to measure the weighing object M such as snacks, the oil or flavor contained in the weighing object M on the conveying surface of the supply trough 3i as the operation time elapses. (Additives, etc.), the powder of the product itself adheres and the feeder transport amount decreases.
For this reason, in order to compensate for the amount of decrease in the feeder conveyance amount, it is necessary to increase the feeder feeding force by an operator's manual or automatic control. In particular, in the continuous operation for a long time, it is necessary to largely change the set value of the feeder feeding force as compared with the initial operation state.

On the other hand, for the purpose of maintaining the quality of the object to be weighed M and preventing mixing when the type of the object to be weighed M is changed, the deposit is removed (cleaned) from the feeder transport surface in the production process. As a result of this cleaning operation, the feeder conveyance amount returns to the initial state.
However, as described above, the feeder feed force setting value that has become a large value due to long-time operation remains stored in the storage unit. Therefore, at the start of the next operation, based on the previous set value read from the storage unit, the combination weighing device 400 operates with a transport amount much larger than the required transport amount of the object to be weighed M. As a result, the defect rate increases and the operating rate decreases.

  Therefore, a plurality of feeder feeding power storage areas are provided for the same reservation. Specifically, in the storage area, “initial operation”, “stable operation (initial)”, “stable operation (late)”, etc. are stored in chronological order, and the area stored according to the number of operations is automatically or Set to be able to change manually. These stored contents can be freely selected or changed at the time of reservation change or operation, and are set so that they can be stored at any time.

  In this way, by setting the storage area, it is possible to store the appropriate feeder feed force setting values for the initial, middle and late periods of operation in the same reservation. It is possible to optimize and store the set value of the power transmission in time series. Accordingly, stable operation from the start of operation of the combination weighing device 400 to the end of production can be realized, and productivity can be improved.

  By the way, in the combination weighing device 400, a supply trough (dispersion feeder) 3i is arranged for the purpose of dispersing the supplied object M and supplying it to each pool hopper body 4i. Conventionally, there has been proposed a device that automatically adjusts the feeder feeding force of each of these supply troughs 3i to obtain an optimum value in accordance with the operation status (Japanese Patent Application Laid-Open No. 2004-177375, Japanese Patent Application Laid-Open No. 2005-55187, and Japanese Patent Application Laid-Open No. 2005-55187). 2005-249457).

Here, conventionally, the combination weighing device 400 stores upper and lower limit values determined to limit the control range of the feeding force of the supply trough 3i. The upper and lower limit values are provided in order to prevent inconvenience that the feeder feeding force control described below diverges.
That is, for example, when the supply of goods from the previous process is interrupted with respect to some of the supply troughs 3i, the feeder feeding force of the supply troughs 3i is increased to increase the supply amount to the pool hopper. Controlled to continue.
On the other hand, if the weighing object M is supplied even if the supply trough 3i is stopped because the supply amount of the weighing object M is too large, the feeder feed force is controlled to continue to decrease.
Therefore, the upper and lower limit values are set to values that restrict the upper and lower limits so that the feeder feed force setting value does not become too large or too small.

  However, the upper and lower limit values are manually set, and it is necessary to repeat trial and error in order to set an appropriate value depending on the experience and intuition of the operator. For this reason, it is difficult to set appropriate upper and lower limit values, and as a result, the feeder feed force rises or falls to an inappropriate value, and there is a problem that stable operation cannot be performed.

  Therefore, referring to the feeder feed force (RF intensity) during operation (feeder feed force control), the upper and lower limits defined as a percentage (%) with respect to the median value of the manipulated variable (value approximating the average value) Find the value and control between them. The median value is adopted instead of the average value. If the average value is used, the RF intensity at which the divergence starts increases (or decreases) the overall average value. The calculation method is performed by extracting the median value from the total RF intensity.

  Thus, by setting, it is possible to have upper and lower limit values autonomously without depending on the operator, so that divergence is suppressed and stable operation is possible. As a result, productivity can be improved by realizing stable operation from the start of operation to the end of production.

By the way, as a method for limiting the access level of the combination weighing device 400, the alignment device 200, and the like, a password, an ID card, a key (Dalasky), and the like are conventionally used. On the other hand, in the machine industry, hard switches are often used for operations such as start and stop of operation.
However, it is not reasonable because the method of specifying the driver and restricting access is different from the method of starting and stopping the driving.

Therefore, for example, a key having a storage unit composed of a stick-shaped USB memory or the like in which operator information, drive details, screen shortcut information, and the like are stored in advance is prepared, and the device is operated as follows.
The USB memory stores the operation level and drive content along with the stored content. The storage contents are stored in the USB memory from an operation panel of the personal computer, the combination weighing device 400, the alignment device 200, or the like.
The USB memory is inserted into a keyhole-shaped USB socket formed in the combination weighing device 400 or the alignment device 200, and the USB memory is rotated. By rotating the USB memory, it is possible to drive with a function corresponding to information stored in the USB memory.

  Even if the USB memory (key) is removed, the device may be set to have the function. In that case, when the key is removed, the operation level becomes the lowest level, and only the stop key may be validated. In order to ensure safety, only a key for stopping may be prepared separately.

For example, if the drive content stored in the USB memory (key) is set to “driving”, the key is used as a start / stop key for driving and can be operated according to the level of the operator. The
Further, by storing operator information in the USB memory, an operator who can operate the operation panel can be specified.
Furthermore, while the operator is working, it is possible to record the operator name and summarize the usage status of the device in a report.

In addition, since the start / stop is performed by turning the key, the device can be driven and stopped intuitively, so that there is no sense of incongruity in the operation feeling.
Alternatively, a telephone number (for example, 110) may be separately stored in a USB memory so that a predetermined telephone number can be called when connected to a mobile phone. This is the opposite of the child's crime prevention bell, and the crime prevention bell rings when the key is turned. However, the crime prevention bell has no meaning unless the surrounding people notice it. On the other hand, in this structure, since the telephone contact can be simply performed to the police and the person who wants to contact, more effective safety ensuring is attained.

  The present invention can be applied to a combination alignment system.
