しかし前述した従来の逆転防止装置での(1) は、この防止装置をポータブルコ ンベヤに使用すると重量が重くなって移動が困難となる。そのため、移動が容易 とする目的のポータブルコンベヤ等には用いることができない。また(2) は、防 止装置自体の単価が高価であるので、コンベヤ全体としても高額なものとしてし まう。さらに(3) は、故障時の取り替えや整備が、特殊道工具が必要である等か ら困難なものとなる。また(4) は、安価で特殊道工具を使用することもなく、素 人でも容易に取付けることが可能な装置であるが、爪25が歯車24へ噛み込む防止 動作を確実に行わないことがある。 However, in case (1) of the conventional reverse rotation prevention device described above, if this prevention device is used in a portable conveyor, the weight becomes heavy and it becomes difficult to move. Therefore, it cannot be used for a portable conveyor or the like for the purpose of easy movement. In (2), since the unit cost of the protective device itself is expensive, the conveyor as a whole will be expensive. Furthermore, in (3), replacement and maintenance in case of failure are difficult because special road tools are required. In addition, (4) is a device that is inexpensive and can be easily installed by an amateur without using a special tool, but it does not reliably prevent the pawl 25 from being caught in the gear 24. is there.

以下、この考案のベルトコンベヤの逆転防止装置を、図示する実施例によって 説明する。 The belt conveyor reverse rotation prevention device of the present invention will be described below with reference to the illustrated embodiment.
【０００８】 逆転防止装置１（図１参照）は、ベルトコンベヤ２のリターン側におけるベル ト３上面に接触して配設され、ベルト３との摩擦力によりベルト３の移動に伴っ て移動自在な逆転防止部材４を有してなっている。The reverse rotation preventing device 1 (see FIG. 1) is arranged in contact with the upper surface of the belt 3 on the return side of the belt conveyor 2 and is movable with the movement of the belt 3 due to the frictional force with the belt 3. The reverse rotation prevention member 4 is included.
【０００９】 そして逆転防止部材４は、ベルト３におけるリターン方向であるベルトコンベ ヤ正転方向への移動が拘束され、またリターン方向とは逆方向であるベルトコン ベヤ逆転方向への移動が自在であると共に、リターン方向とは逆方向への移動時 にベルト３と駆動プーリー５との間に嵌入して噛み込まれるように配設されてい る。The reverse rotation preventing member 4 is constrained from moving in the belt conveyor forward rotation direction, which is the return direction of the belt 3, and is free to move in the belt conveyor reverse rotation direction, which is the reverse direction to the return direction. At the same time, it is arranged so as to be fitted and caught between the belt 3 and the drive pulley 5 when moving in the direction opposite to the return direction.
【００１０】 なおこの実施例における逆転防止部材４は、図２に示すように、コンベヤフレ ーム６に固定さているチェーン７と、このチェーン７に一端が固定されていると 共に、他端がベルト３に接触している板体状の防止部材本体８とからなっている 。この防止部材本体８は、例えばベルト片等のものが使用される。As shown in FIG. 2, the reverse rotation preventing member 4 in this embodiment has a chain 7 fixed to the conveyor frame 6, one end fixed to the chain 7, and the other end being a belt. 3 and a plate-shaped prevention member main body 8 that is in contact with 3. As the prevention member body 8, for example, a belt piece or the like is used.
【００１１】 このような構成からなる逆転防止装置１を使用しての逆転防止動作は、次のよ うにして行われる。The reverse rotation preventing operation using the reverse rotation preventing device 1 having such a configuration is performed as follows.
【００１２】 まず、図１の(A) にベルトコンベヤ２のベルト３が正転方向へ移動する正常稼 動時における逆転防止装置１の状態を示す。First, FIG. 1A shows the state of the reverse rotation preventing device 1 at the time of normal operation in which the belt 3 of the belt conveyor 2 moves in the normal rotation direction.
【００１３】 ここでの、ヘッドプーリーである駆動プーリー５近傍に取り付けられた逆転防 止部材４の防止部材本体８は、リターン側のベルト３上で、ベルト３の移動方向 に引かれて、駆動プーリー５から離れる。この状態で防止部材本体８は、コンベ ヤフレーム６に固定されたチェーン７によって拘束されており、駆動プーリー５ から一定の距離をもってその位置に停留している。Here, the prevention member body 8 of the reverse rotation prevention member 4 mounted near the drive pulley 5, which is the head pulley, is pulled on the return side belt 3 in the moving direction of the belt 3 to drive. Move away from pulley 5. In this state, the prevention member main body 8 is constrained by the chain 7 fixed to the conveyor frame 6 and stays at that position with a certain distance from the drive pulley 5.
【００１４】 次に、図２の(B) にベルトコンベヤ２のベルト３が逆転方向へ移動する、ベル トコンベヤ２の逆転が発生した場合の、逆転防止装置１の作動状態を示す。Next, FIG. 2B shows an operating state of the reverse rotation preventing device 1 when the belt 3 of the belt conveyor 2 moves in the reverse direction and the reverse rotation of the belt conveyor 2 occurs.
【００１５】 ここでは、ベルト３の動力源が無くなった時点でベルト３上の負荷の重力で逆 転が始まる。そしてリターン側のベルト３上に接触している逆転防止部材４の防 止部材本体８は、ベルトコンベヤ２の逆転と同時に、駆動プーリー５側へ近ずい て、駆動プーリー５とベルト３との間に噛み込まれて駆動プーリー５に巻き込ま れて行く。Here, when the power source of the belt 3 disappears, the reverse rotation starts due to the gravity of the load on the belt 3. The anti-reverse member 4 of the anti-reverse member 4, which is in contact with the belt 3 on the return side, approaches the drive pulley 5 side at the same time as the reverse rotation of the belt conveyor 2, and the space between the drive pulley 5 and the belt 3 is approached. Is caught in and is caught in the drive pulley 5.
【００１６】 その後逆転防止部材４の防止部材本体８は、コンベアーフレーム６から控をと っているために、ベルト３が逆転による移動を一定の距離だけ行えば固定される こととなり、ベルト３の移動が強制的に停止させられてベルトコンベヤ２の逆転 が停止する。After that, the prevention member main body 8 of the reverse rotation prevention member 4 is kept from the conveyor frame 6, so that the belt 3 will be fixed if the movement due to the reverse rotation is performed for a certain distance, and the belt 3 is fixed. The movement is forcibly stopped and the reverse rotation of the belt conveyor 2 is stopped.
【００１７】 なお逆転防止部材４の防止部材本体８は、ベルトコンベア２の状況によって， 前述した実施例で使用したベルト片等の板体状の他に、ワイヤーやチェーンおよ びロープ等を使用しても良い。即ち、逆転防止部材４の防止部材本体８としては 、駆動プーリー５とベルト３との間に噛み込まれて、駆動プーリー５に巻き込ま れることのできるものならば、どのようなものであっても良い。Depending on the condition of the belt conveyor 2, the prevention member body 8 of the reverse rotation prevention member 4 uses not only a plate-like member such as the belt piece used in the above-described embodiment but also a wire, a chain, a rope, or the like. You may. That is, the prevention member main body 8 of the reverse rotation prevention member 4 may be any one as long as it can be caught between the drive pulley 5 and the belt 3 and can be wound around the drive pulley 5. good.
