本発明は円筒形コンベヤに於ける過負荷の検出
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for detecting overload in a cylindrical conveyor.
（従来技術）
円筒形コンベヤに於いて、大塊や長尺物等の異
物が混入すると、円筒状に配置した保形ローラ部
でつかえ、ベルトが損傷したり縦裂きを起こした
りする。(Prior Art) When a foreign object such as a large lump or a long object gets mixed into a cylindrical conveyor, it gets stuck in the cylindrically arranged shape-retaining roller section, causing damage to the belt or vertical tearing.

この方法だけでは過負荷を防止したり、長尺物等
の混入に依るベルトの損傷、縦裂きを防止するこ
とはできないので、その対策がのぞまれていた。 At present, when troubles such as those described above occur in cylindrical conveyors, almost no countermeasures have been taken against the overload of the conveyor. However, to prevent objects larger than the cylindrical cross-sectional area of the cylindrical conveyor from entering the chute of the upstream conveyor, the cross-sectional area of the chute exit was limited or a gate was installed.
This method alone cannot prevent overloading or damage or vertical tearing of the belt due to long objects being mixed in, so countermeasures have been desired.

If detected, the conveyor is stopped to prevent serious accidents such as damage to the belt along the entire length of the conveyor, vertical tearing, etc.

The support frame closest to the chute is pivotally supported on a base so as to be tiltable in the belt traveling direction, and is characterized by being equipped with a tension gauge that responds to the tension in the belt traveling direction.

枠である。(Embodiment of the Invention) FIG. 1 shows a cylindrical conveyor in which the present invention is implemented, 1 is a conveyor belt, and objects to be transported are inputted from a chute 2 . Reference numeral 3 denotes a support frame that supports a plurality of shape retaining rollers 4 that retain the shape of the conveyor belt 1 in a cylindrical shape.

で電磁石１０によつて常時は密着している。 5 is the support frame 3 located closest to the chute 2
This is a tension gauge installed between the block 7 and the block 7 fixed on the base 6. The support frame 3 has a pair of left and right lower frames 3a.
and one end is pivotally supported on the lower frame 3a by a pin 9,
It consists of a pair of L-shaped upper opening/closing valves 3b that can be separated at the top and can be opened laterally. As shown in FIGS. 2 and 3, the lower frame 3a of the support frame 3 closest to the chute 2 is pivotally supported on the base 6 by pins 8, and is tiltable in the direction of belt movement. The upper opening/closing frames 3b, 3b on both sides are always in close contact with each other by an electromagnet 10 at the top split surface.

電動シリンダーでも代替可能である。 The electromagnet 10 and the tension meter 5 are interlocked, and the electromagnet 10 is demagnetized at the same time as an overload is detected, so that the opening/closing frame 3b loses its holding force. Reference numeral 11 denotes a tension spring stretched between the upper part of a bracket 12 fixed to the side of the upper opening/closing frame 3b and the side of the lower frame 3a. Note that the attraction force of the electromagnet 10 is greater than the spring force of the tension spring. Further, the electromagnet 10 can be replaced by an electric cylinder.

は基台６に固定されベルト進行方向に倒れない。 As shown in FIG. 2, the lower frame 3a closest to the chute 2 is pivoted to the base 6 so as to be tiltable in the direction of belt movement, but the second and subsequent ones are fixed to the base 6. The belt will not fall in the direction of travel.

る。 The upper opening/closing mechanism is installed in a range that takes into account the coasting distance of the belt from the conveyor stop command until the conveyor comes to a complete stop. Remove the area until the cross-sectional area becomes below the normal transport cross-sectional area and resume operation.

部分はすべてＵ字形トラフとなる。(Function) When a large mass to be transported 13 (Fig. 3) whose cross-sectional area is larger than that of the conveyor is fed from the chute 2 into the cylindrical conveyor, the cylindrical belt is moved to an appropriate cylindrical cross-section by the shape-retaining rollers 4. is not maintained, the deformed portion gets stuck in the shape retaining roller, and an abnormal load acts on the lower frame 3a in the belt traveling direction. Then, the lower frame 3a is tilted in the belt traveling direction about the hinge pin 8, and the tension meter 5 is pulled to detect an abnormal load and stop the cylindrical conveyor. At the same time, the electromagnet 10 is demagnetized and loses its holding force, and the tension spring 11 attached to the lower frame 3a
As a result, the upper opening/closing frame 3b opens around the lower pin 9, and the belt cross section changes from a circle to a U-shaped trough, and the cylindrical conveyor stops in this state. At this time, all of the electromagnetic opening/closing mechanisms of the upper opening/closing frames provided within the belt coasting distance are all opened, and this portion becomes a U-shaped trough.

とにより、上部開閉枠３ｂは固定される。 Once the cylindrical conveyor has stopped, the large block conveyor 13 that caused the trouble is removed from the conveyor, which has become a U-shaped trough with its top open, and the conveyor returns to its cylindrical shape and restarts operation. To restore the cylindrical conveyor to its original state prior to restarting, the upper opening/closing frame 3b is manually closed and the electromagnet is activated to fix the upper opening/closing frame 3b.

等を防止することができる。(Effect of the invention) Since the support frame closest to the chute of the cylindrical conveyor can be tilted freely in the belt traveling direction, if a large lump is mixed in the conveyor, this large lump will tilt the support frame and prevent it from moving. Accordingly, the tension gauge was activated, the upper opening/closing frame was opened, and the conveyor was stopped. As a result, excessive force is not sustained on the conveyor belt, and damage to the belt, vertical tearing, etc. can be prevented.
