Description

[Detailed description of the invention] This invention relates to an automatic weighing device that automatically weighs linear products such as dried noodles, and in particular, to improve the weighing ability by quickly and reliably discharging linear products from the weighing hopper to the bucket. With the goal.

This type of automatic weighing device is provided with a conveyor using a bucket to automatically supply linear articles weighed by a weighing hopper to a packaging machine, a binding machine, or the like.

The transport conveyor endlessly circulates a large number of buckets between a weighing hopper and an input port of a packaging machine, etc., and the buckets are turned over at a predetermined position to discharge the articles. The bucket bag 1 has a U-shaped holding part 2 at the rear, as shown in FIG. It has a structure in which a bottom part 3 in front of the holding part 2 is extended forward, and an opening part 4 is formed by bending the end part upward.

Then, the linear article 6 is discharged from the weighing hopper 5 into the opening 4 of the bucket 1, and the linear article 6 is
is transferred to the holding section 2.

By the way, when discharging the linear article 6 from the weighing hopper 5 to the bucket 1, if it is a small amount, the linear article 6
are reliably accommodated in the holding part 2 from the opening 4 of the bucket 1, but if the linear articles 6 are in large quantities, they will accumulate in the opening 4 of the bucket 1 and swell up, causing the bucket 1 to
Since there is a risk that the linear articles 1 will be discharged to the upper surface and fall from the bucket 1 during transportation, the linear articles 1 should be dispersed widely so that they do not pile up and are not discharged onto the upper surface of the holding part 2 of the bucket 1. It is discharged to the front. As a result, the opening 4 of the bucket 1 had to be enlarged, and the bucket 1 became large. As a result, the feeding pitch of the bucket cart 1 becomes longer, which reduces the weighing capacity.In addition, when the bucket cart 1 is circulated endlessly, the conveyor must be constructed in a large size to prevent adjacent bucket carts from interfering with each other at the reversing section. I had a problem that I didn't have.

This invention is an improvement and elimination of the above-mentioned problems, and includes a swingable regulation plate in front of the discharge port of the weighing hopper that prevents the linear articles from flying out forward and guides them into the bucket. This made the bucket bag smaller and improved its measuring ability.

Examples of this invention will be described below with reference to the drawings.

In FIGS. 2 and 3, 10 is a weighing hopper, which has an input port 11 at the top and a discharge port 12 at the lower front. It can be opened and closed freely by an opening/closing lid 13 pivotally attached to the opening/closing lid 13. Further, claws 14 and 15 are alternately formed protruding from the lower ends of the weighing hopper 10 and the opening/closing lid 13, respectively, and the claws are crossed to prevent the linear article 6 from falling. This weighing hopper 10 is supported by a weighing mechanism 16, and is configured to measure the weight of the supplied linear article 6. Above the input port 11, when the inside of the hopper is empty, an appropriate amount of wire is placed. A feeding mechanism (not shown) is provided for feeding shaped articles 6. 17 is weighing hopper 1
0, a double row of sprocket wheels 19, 19 are provided at both ends of support frames 18, 18 of appropriate length, and chains 20, 20 are endlessly attached to the sprocket wheels 19, 19. It is installed on. and chain 20,20
A support bar 21 is connected therebetween, and a bucket 22 is integrally connected to the upper surface of the support bar 21. The bucket bag 22 has a substantially U-shaped holding portion 23 formed at the rear by bending a single plate, and an opening 24 by bending the front end upward. Further, the upper end of the holding part 23 is slightly inclined downward to hold the linear article 6 in the opening 2.
It is designed to guide you to step 4. 25 is a regulation plate provided in front of the discharge port 12 of the weighing hopper 10;
It has flexibility and is connected to the lower end of the support plate 26. The support plate 26 is pivotally connected via a bracket 29 to a support rod 28 supported on the upper end of a gate-shaped support frame 27 installed between the upper surfaces of the support frames 18,18. Further, a support rod 30 is integrally provided in the front of the support plate 26, and a weight 31 is attached to the support rod 30 to apply a moment load in the counterclockwise direction in the figure to the support plate 26 and the regulation plate 25. Board 2
5 is always in a vertical position. In addition, an escape groove 32 is formed in the lower central part of the regulation plate 25,
Arm parts 33, 33 are formed on both sides of the relief groove 32, so that the bucket 22 passes through the relief groove 32 and does not interfere with the regulation plate 25, and the ends of the linear article 6 protruding from both sides of the bucket 22 is configured to pass while interfering with the arm portions 33, 33 and swinging the regulating plate 25 clockwise. The regulating plate 25 is disposed so as to partially intersect with the tip of the bucket 22 waiting at the lower part of the weighing hopper 10 and the arm parts 33 when in the vertical state to receive the linear article 6.

In the above configuration, to explain its operation, the linear article 6 is supplied from the supply mechanism to the weighing hopper 10, and the weight of the supplied linear article 6 is measured by the weighing mechanism 16.
It will be weighed at When the measured value of the weighing mechanism 16 reaches the set value, the feeding of the linear article 6 from the feeding mechanism is stopped, the opening/closing lid 13 is opened, and the linear article 6 in the weighing hopper 10 is discharged from the discharge port 12. , bucket 2 waiting below the discharge port 12
2. When the ejection of the linear article 6 is completed, the opening/closing lid 13 is closed, the linear article 6 is again supplied from the supply mechanism to the weighing hopper 10, and its weight is measured by the weighing mechanism 16. On the other hand, the bucket 22 containing the linear articles 6 is immediately intermittently fed forward, and during this time, the ends of the linear articles 6 protruding from both sides of the bucket 22 interfere with the arms 33, 33 of the regulating plate 25, causing While being swung forward, the linear article 6 is simultaneously accommodated in the accommodating portion 23 of the bucket 22. Further, a subsequent empty bucket 22 is waiting at the bottom of the weighing hopper 10. After this, weighing hopper 10
The linear articles 6 weighed in are discharged into the bucket 22 in the same manner as described above.

By repeating the above operation, the linear articles 6 weighed in the weighing hopper 10 are sequentially stored in the bucket 22,
Transport to automatic packaging machine, etc.

During the above operation, if there are many linear articles 6 discharged from the discharge port 12 of the weighing hopper 10 into the bucket 22, the articles 6 are discharged forward.
A regulation plate 2 is provided in front of the discharge port 12 of the weighing hopper 10.
5 is provided, and since the arms 33, 33 of this regulating plate 25 partially intersect with the tip of the bucket 22, the linear article 6 hits the regulating plate 25,
Thereafter, it is guided by the regulation plate 25 and sent to the opening 24 of the bucket 22. Furthermore, even if a large amount of linear articles 6 accumulate in the opening 24 of the bucket 22, when the bucket 22 is moved, the ends of the linear articles 6 protruding from both sides of the bucket 22 push the regulation plate 25 forward and swing. The restoring force acts as a reaction on the linear article 6.
Moreover, since the restoring force acts obliquely backward, the linear article 6 is reliably pushed into the storage part 23 of the bucket bag 22 and does not fall out from the bag bag 22. In addition, since the regulating plate 25 is flexible and swingable, it does not apply strong local pressure to the linear article 6, and even brittle linear articles such as dried noodles can be used. There is no risk of breakage.

As explained above, according to this invention, even if the linear articles discharged from the weighing hopper into the bucket are sent forward, the regulation plate installed in front of the weighing hopper prevents them from flying out, and the articles are actively discharged into the bucket. Since the linear articles accumulated in the opening of the bucket are pushed into the storage part of the bucket by the regulating plate during movement, the linear articles do not fall out of the bucket, which prevents measurement errors from occurring. There is no. In addition, since linear articles are actively accommodated by the regulation plate, the bucket can be made smaller, and the feed pitch of the bucket can be shortened, which can speed up the article discharge timing from the weighing hopper, allowing the weighing Your abilities will improve. Furthermore, since the bucket cart is made smaller, even if it is circulated endlessly, the area of interference between adjacent bucket carts in the reversing section is reduced, and the conveyor can be made smaller and the conveyance capacity is improved accordingly.
