Description

Description: TECHNICAL FIELD The present invention relates to a volume measuring machine for linear bodies such as dry noodles, which can perform suitable measurement for fragile linear bodies such as dry noodles, and can provide accurate weighing. The present invention is intended to provide a volume measuring machine of a linear body capable of performing the above.

[Conventional technology]

When measuring and packaging conventional linear objects (dry noodles, etc.), linear noodles that are cut into fixed lengths are fed to the hopper, and while being transported on an oscillating conveyor on an average basis, the lift block scoops up the unit packaging amount to measure the linear shape. A body volume meter is used.

In this conventional example, the transfer amount by the vibrating conveyor and the support amount by the lift block are set so as to correspond to the unit packaging amount, and the transfer is automatically performed.

[Problems to be solved by the invention]

The weighing accuracy of the weighing machine in the conventional example is improved if the density (thickness) of the linear bodies (dry noodles, etc.) posted on the vibrating conveyor can be kept constant at all times, but actually on the vibrating conveyor. It is very difficult to load a fixed amount of dried noodles and transfer it on average, and especially when the transfer of dried noodles is accelerated, it is difficult to time the operation of each part, and it becomes more difficult to load and transfer the fixed amount of dried noodles. Therefore, there is a problem that the measurement accuracy is extremely lowered, and adjustment and measurement adjustment for accurate measurement cannot be performed easily and swiftly.

[Means for solving problems]

This invention is a conveyor (2) that conveys a linear body (1).
And a stocker (3) installed near the end of the conveyor (2) and higher than the upper surface (6) of the linear body (1) being transported, and a unit packaging amount of more than the unit packaging amount from the conveyor (2). A lift block (4) for picking up the linear body (1) and putting it into the stocker (3) and the linear body (1) raised on the upper surface of the stocker (3) are placed on the conveyor (2). The stocker (3) has a scraping plate (5) to be swept off, and the stocker (3) has a substantially V-shaped linear body accommodating space formed by an inclined plate and an opening / closing plate, and the opening / closing plate is driven by a stepping motor (10). The above problem is solved by means of rocking by means of the above-mentioned method.

The inclined plate is not limited to the one that is literally inclined, and means a plate that forms a substantially V-shaped linear body accommodating space with the opening / closing plate.

[Action]

The linear body conveyed by the conveyor is scooped by the lift block and put into the stocker, and the linear body raised on the upper surface of the stocker is swept up by the scraping plate onto the conveyor and the linear body in the stocker is weighed. After that, the opening / closing plate is swung downward by the stepping motor to open the lower end of the stocker, and a predetermined amount of linear body is dropped from the stocker. The above is the measuring operation of the linear volume measuring machine of the present invention.

The stocker has a substantially V-shaped linear body accommodating space formed by the inclined plate and the opening / closing plate, and the volume of the substantially V-shaped linear body accommodating space is changed by adjusting the closing position of the opening / closing plate. Since the opening / closing plate is driven to be opened / closed by a stepping motor capable of finely and accurately setting the stop position and the swing angle, the closing position of the opening / closing plate is adjusted by setting the stop position and the rotation angle of the stepping motor. Very fine, precise, easy and fast to adjust. Therefore, by controlling the closing position of the stepping motor, the weighing value of the stocker can be adjusted and changed extremely finely, accurately, easily and quickly.

〔Example〕

An embodiment of the linear body volume measuring machine of the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 5, 2 is a vibrating conveyor that conveys the linear body 1 made of dried noodles and the like, and the linear body 1 is supplied to an average height and becomes vibrable by the vibration. There is.

A stocker 3 is installed near the end of the conveyor 2 and higher than the upper surface 6 of the linear body 1 being conveyed. The stocker 3 is rotatably mounted by a shaft 9 of a stepping motor 10 at a predetermined interval in the horizontal direction from an upper end of the inclined plate 7 and an inclined plate 7 hanging downward from the tip of the conveyor 2. The opening / closing plate 8 and the inclined plate 7
A space having a substantially V-shaped cross section is formed between the opening and the closing plate 8 and the linear body 1
Is to be stocked. The stocker 3 can discharge the linear body 1 by opening the lower surface by driving the stepping motor 10 to rotate the lower end of the opening / closing plate 8 to the right.

The conveyor 2 is provided with an opening 11 at the end of the conveying path, and a lift block 4 is provided so that it can be raised and lowered so as to project and retract from the opening 11. This lift block 4
Is formed so that the upper end thereof is inclined toward the stocker 3 side, but it is particularly preferable to make the stocker 3 side substantially flat. By doing so, it is possible to prevent the linear body 1 from being broken due to friction with the vertical portion on the stocker 3 side.

The lift block 4 scoops up the linear body 1 in a unit packaging amount or more from the conveyor 2 and loads it into the stocker 3.

In this way, the linear bodies 1 scooped up by the lift block 4 in a unit packaging amount or more are piled up on the stocker 3. Stepping motor 2 on stocker 3
The scraping plate 5 is rotatably mounted on the shaft 22 of No. 1. The scraping plate 5 has returned to the opening / closing plate 8 side of the stocker 3 before the lift block 4 is lifted, and the linear body 1
When is mounted on the stocker 3 and becomes a heap, it is rotated by the stepping motor 21 to sweep the linear body 1 onto the conveyor 2.

In addition, the linear body 1 weighed in the unit packaging amount is the stocker 3
By opening the opening / closing plate 8 of the above, the container is put into the weighing hopper 23 in the downward direction. After that, the opening / closing plate 8 returns to the original state, but the volume in the stocker 3 can be adjusted according to the step angle at this time. The window 24 provided on the opening / closing plate 8 is for overlapping the opening / closing plate 8 and the scraping plate 5.

Since the conventional device does not have the scraping plate 5, the linear members 1 in the stocker 3 return to the conveyor 2 little by little due to the vibration of the conveyor 2 after the lift block 4 descends. However, in the linear body volume measuring machine of the present invention, the weighing speed is high by operating the scraping plate 5, and a weighing error caused by the state of the linear body 1 on the stocker 3 or the linear body 1 on the conveyor 2 is caused.
The error caused by the height of is also eliminated.

Further, the stocker 3 has a substantially V-shaped linear body accommodating space formed by the inclined plate 7 and the opening / closing plate 8, and the substantially V-shaped linear body accommodating space is adjusted by adjusting the closing position of the opening / closing plate 8. The volume changes. Since the opening / closing plate 8 is driven to open / close by a stepping motor 10 capable of finely and accurately setting a stop position and a swing angle, the closing position of the opening / closing plate 8 is adjusted by stopping and rotating the stepping motor 10. By setting the angle, adjustment is extremely fine, precise, easy and quick. Therefore, the above stepping motor 1
By controlling the closed position of 0, the weighing value of the stocker 3 can be adjusted and changed extremely finely, accurately, easily, and quickly.

FIG. 6 shows another embodiment of the linear body volume measuring machine according to the present invention, in which the opening / closing plate of the stocker 3 is bent outward and then folded back inward to increase the capacity of the stocker 3 and increase the surface area of the stocker 3. It is possible to improve the measurement accuracy by reducing the. Of course, in this case, it is necessary that the shapes of the linear bodies 1 are well aligned.

Next, the operation of the volume measuring machine will be described.

First, the linear body 1 made of dry dried noodles is vibrating on the conveyor 2 as shown in FIG. At this time, the stocker 3 can store the linear body 1 by closing the opening / closing plate 8. The scraping plate 5 is returned to the opening / closing plate 8 side.

Next, as shown in FIG. 3, the lift block 4 rises, and the linear body 1 having a unit packaging amount or more is loaded onto the stocker 3. At that time, the linear bodies 1 are piled up a lot on the stocker 3 by the lift block 4, and even if the lift block 4 descends thereafter, the linear body 1 is piled up on the stocker 3.

Then, the stepping motor 21 is driven to rotate the scraping plate 5 so that the tip of the scraping plate 5 sweeps the upper surface of the stocker 3 to move the linear body 1 raised on the stocker 3 to the conveyor as shown in FIG. Sweep up to 2. The linear body 1 whose volume has been measured in this way is loaded from the stocker 3 into the downward weighing hopper 23 by opening the opening / closing plate 8 as shown in FIG.

Thereafter, as described above, the opening / closing plate 8 and the scraping plate 5 are returned to the original state, and one step is completed.

〔The invention's effect〕

Since the linear body volume measuring machine of the present invention is configured as described above, it is not necessary to keep the density (thickness) of the linear bodies (dry noodles, etc.) stacked on the vibrating conveyor so strictly constant.
Therefore, the packaging process can be significantly speeded up as compared with the conventional method in which it is essential to supply a fixed amount of dry noodles on the vibration conveyor. That is, in the present invention, it is improved to 30 times / min as compared with the conventional measuring speed of 15 times / min.

Further, since the volume of the volume accommodated in the stocker 3 can be electrically controlled only by setting the stop position of the opening / closing plate 8 to a predetermined angle by the stepping motor 10, the volume is calculated based on the data obtained from the weight calculator 23. The amount can be feedback controlled and the accuracy can be improved.
