図示せぬ制御盤に接続され、上昇カム３８が反時
計方向に回転した場合これを検出する。 The rising cam 38 can rotate about a shaft 40 driven into the bracket 39 as a fulcrum. The bolt 41 is screwed into a boss that is part of the bracket 39,
Its tip restricts the clockwise rotation of the ascending cam 38. 42 is an air cylinder, and a push head 51 is fixed to the tip thereof. 43 is the abutment, 44
is an air tank, 45 is a pressure reducing valve, 46 is a pressure gauge,
47 is a three-way tank, and these are connected to an air source 48 by a pipe 49. 50 is a proximity switch,
It is connected to a control panel (not shown) and detects when the rising cam 38 rotates counterclockwise.
第３図はブラケツト３９の斜視図である。 FIG. 3 is a perspective view of the bracket 39.
次に本装置の作用を説明する。 Next, the operation of this device will be explained.
第１図において、タンクの高さ設定に誤りがな
ければ昇降軸３４が上昇し充填、下降工程は従来
技術と全く同一である。 In FIG. 1, if there is no error in setting the height of the tank, the lifting shaft 34 will rise, and the filling and lowering processes are exactly the same as in the prior art.
タンクの高さ設定を誤りタンクが低過ぎる場合
を第２図で説明する。 A case where the height of the tank is set incorrectly and the tank is too low will be explained with reference to FIG.
上昇カム３８はその口の部分で押し頭５１を介
しエアーシリンダー４２の作用力を受けていると
ともにボルト４１により時計方向の回転をストツ
プされている。 The rising cam 38 receives the force of the air cylinder 42 through the push head 51 at its mouth, and is stopped from rotating clockwise by the bolt 41.
エアーシリンダー用エアーはエアー源４８より
供給され減圧弁４５で調圧供給されている。 Air for the air cylinder is supplied from an air source 48, and the pressure is regulated by a pressure reducing valve 45.

ルブ１７はフルストロークし、それ以上容器は上
に上昇できない。さらに回転テーブル１は回転す
る結果、上昇カム３８はローラ５より力を受け、
この力がエアーシリンダー４２の作用力に打ち勝
つて３８′まで下降する。 When the rotary table 1 rotates now, the elevating shaft 34 moves up along the elevating cam 38 via the roller 5, and the container 1
6 is pushing up the filling valve 17, the filling valve 17 is fully stroked and the container cannot rise any further. Furthermore, as a result of the rotation of the rotary table 1, the rising cam 38 receives a force from the roller 5,
This force overcomes the acting force of the air cylinder 42 and descends to 38'.
そのときエアーシリンダー４２の押し頭５１は
５１′まで動く。この時点で近接スイツチ５０は
上昇カムが３８′に位置するのを検出し充填機の
運転を停止させる信号を発する。 At that time, the push head 51 of the air cylinder 42 moves to 51'. At this point, proximity switch 50 detects the raising cam at 38' and issues a signal to stop operation of the filling machine.
エアータンク４４の働きは、エアーシリンダー
の押し頭５１が５１′まで動かされた場合エアー
シリンダー４２内のエアーは容積が減少する。今
PV＝一定（Ｐ＝エアー圧、Ｖ＝容積）の法則で
圧力が上昇する。この圧力上昇をできるだけ小さ
くしカム３８に作用する力をできるだけ一定にす
るには、
P1V1
（上昇カム位置３８）＝P2V2
（上昇カム位置３８′）
より P2＝P1×V1／V2＝P1×V1／（V1−△Ｖ）
（△Ｖ：減少容積）
＝P1×１／（１−△Ｖ／V1）
V1が大きな程圧力上昇は少い。この目的で４
４のエアータンクを設ける。 The function of the air tank 44 is that when the push head 51 of the air cylinder is moved to 51', the volume of the air inside the air cylinder 42 is reduced. now
Pressure increases according to the law of PV = constant (P = air pressure, V = volume). In order to minimize this pressure increase and keep the force acting on the cam 38 as constant as possible, P 1 V 1 (rising cam position 38) = P 2 V 2 (rising cam position 38'), P 2 = P 1 × V 1 /V 2 =P 1 ×V 1 /(V 1 -△V) (△V: volume reduction) =P 1 × 1/(1 - △V/V 1 ) The larger V 1 is, the smaller the pressure rise will be. stomach. For this purpose 4
4 air tanks are installed.
タンク高さを正規に設定しなおせば、カム３８
は下に下がらず、正常な運転ができる。 If the tank height is set correctly, the cam 38
does not drop and can be driven normally.
保守点検時など昇降軸３４を上昇させたくない
場合は、３方コツク４７を切換えエアーシリンダ
ー４２内のエアーを逃がせばカム３８は３８′ま
で下がり容器昇降装置の昇降軸３４も一緒に下が
る。この状態で充填機を回せば全ての昇降軸３４
は下がつたままとなる。 If it is not desired to raise the lifting shaft 34 during maintenance or inspection, the cam 38 is lowered to 38' by switching the three-way cock 47 to release the air in the air cylinder 42, and the lifting shaft 34 of the container lifting device is also lowered together. If you turn the filling machine in this state, all the lifting shafts 34
The bottom will remain hanging.
もとに戻す時は３方コツク４７をもとに切換
え、エアーシリンダー４２にエアーを供給すれば
上昇カム３８は正規の状態に復元する。 When returning to the original state, switch the three-way cock 47 and supply air to the air cylinder 42 to restore the ascending cam 38 to its normal state.
以上のように本発明装置によれば、容器昇降装
置は構造シンプルとなり、カムにのみ安全装置を
付けたので、部品点数が非常に少くなり、コスト
低減がはかれるとともに、故障も減少する。
As described above, according to the device of the present invention, the container lifting and lowering device has a simple structure and only the cam is equipped with a safety device, so the number of parts is extremely reduced, cost is reduced, and failures are also reduced.
また容器昇降装置を所望のときに上昇させない
事ができるので、型換、充填バルブの取外し、
CIPアタツチメントの取付等の時の作業容易化が
図れる。 In addition, since the container lifting device can not be raised when desired, it is possible to change the container, remove the filling valve, etc.
Easier work when installing CIP attachments, etc.
