【考案の詳細な説明】
本考案は受入れた被供給物の排出速度を制限する溜めホ
ッパーに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sump hopper that limits the rate of discharge of received material.
従来、溜めホッパーは一定開度の排出用ゲートを有し、
所定速度以上での被供給物の排出を制限している。Conventionally, a sump hopper has a discharge gate with a fixed opening.
Discharge of the material to be supplied is restricted at a speed exceeding a predetermined speed.
しかし、貯蔵量に係わらず前記所定速度は一定であるた
め、被供給物が間歇的に供給される場合には排出が平滑
的に行われず、断続的に行われる可能性が極めて大きい
。However, since the predetermined speed is constant regardless of the amount stored, if the material to be supplied is intermittently supplied, there is a very high possibility that the discharge will not be carried out smoothly and will be carried out intermittently.
また、溜めホッパーへの供給量が排出速度に比べて多く
、貯蔵量が増加傾向にあるにも係わらず所定速度以上の
排出を制限しているため、溜めホッパーがオーバーフロ
ーを起こす可能性があり、大きな溜めホッパーを必要と
していた。In addition, the amount supplied to the storage hopper is larger than the discharge speed, and even though the storage amount is increasing, it is restricted from discharging above a certain speed, so there is a possibility that the storage hopper will overflow. A large sump hopper was needed.
そこで本考案は上記欠点に鑑みて威されたものであって
、貯蔵量の増減に伴って溜めホッパーの排出用ゲートの
開度を制御し、排出速度を調節する溜めホッパーを提供
するものである。Therefore, the present invention was developed in view of the above-mentioned drawbacks, and provides a storage hopper that controls the opening degree of the discharge gate of the storage hopper and adjusts the discharge speed as the storage amount increases or decreases. .

排出を開始する。The drive device 6 is commanded to open the gate 7 through the delay circuit 17 at the time when the coincidence detection section 15 detects the coincidence and the gate 3 is completely closed, and starts discharging the stored material in the weighing hopper 4. do.
この時、累積加算部9はゲート7の開放を命令する信号
によって排出開始直前の計重装置50計重値を累積加算
する。At this time, the cumulative addition unit 9 cumulatively adds the weight value of the weighing device 50 immediately before the start of discharging in response to a signal commanding the opening of the gate 7.

The driving device 2 is commanded to open the gate 3 at the time when the gate 3 is closed.

ート制御部13にゲート11の閉鎖を命令する。Objects to be weighed are intermittently received from the weighing hopper 4, and the storage amount is detected by the level meter 14 in the storage hopper 10. When the storage amount decreases to a predetermined level A or less, the next measurement is performed with the gate 11 open. It is determined that the discharge of the stored amount has been completed by the time of supply from the heavy hopper 4 and there is no trace of discharge, and the gate control unit 13 is commanded to close the gate 11.

対してゲート11の開放を命令する。Next, the supply from the weighing hopper 4 is performed, and when the storage amount in the reservoir hopper 10 exceeds the predetermined level A, it is determined that the reservoir hopper 10 will overflow when discharged from the gate 12, and the level meter 14 &l'-to control is performed. The unit 13 is ordered to open the gate 11.
ゲート11が開放されると、ゲート12のみの開放時に
比べ排出速度が増大し、貯蔵量の減少速度も増大する。When the gate 11 is opened, the discharge rate increases and the storage amount decrease rate also increases compared to when only the gate 12 is opened.

できる。Therefore, the discharge from the storage hopper 10 is performed smoothly without leaving any traces, and since there is no overflow, the capacity of the storage hopper 10 can be reduced.

ッパーの容量を小さくすることができる。As explained above, according to the present invention, a level meter for detecting the amount of the object to be weighed stored in the storage hopper and a control section for controlling the opening degree of the discharge gate using the level meter are provided, and the amount of the stored object is increased or decreased. Since the system is configured to control the discharge speed based on the above information, even though the material is supplied intermittently, it can be discharged smoothly without any traces, and the capacity of the storage hopper can be reduced. can.

下する。Additionally, when the storage amount in the sump hopper increases, it is possible to prevent overflow by restricting the input from the weighing hopper to the sump hopper. Capacity decreases.
しかし、本考案では溜めホッパー自身の排出能力を制御

前述のような供給能力の低下が発生しないものである。However, in the present invention, the discharge capacity of the storage hopper itself is controlled and the input from the preceding weighing hopper is not restricted.
This does not cause a decrease in supply capacity as described above.
