2. Description of the Related Art In a manufacturing process, a cartridge case in which a video tape cartridge or the like is stored is transported by a cartridge case transport system after a packaging process in which the entire case is packaged, and each is packaged in a small box. The conventional cartridge case transport system is roughly
It comprises a conveyor belt conveyor for horizontally conveying the cartridge case from the packaging step, and a turret for carrying out the cartridge case vertically conveyed by the conveyor belt conveyor in the vertical direction.

Further, this cartridge case transport system is arranged between a cradle on which a cartridge case that is vertically raised by a turret and carried out is placed, and an end of the transport belt conveyor and the turret. And a stopper member that temporarily holds the cartridge case conveyed by the conveyor belt conveyor.

The conveyor belt conveyor comprises a conveyor belt for conveying the cartridge case, a plurality of support rollers for supporting the conveyor belt, and a belt drive mechanism for traveling the conveyor belt. The conveyor belt conveyor conveys the cartridge case placed on the conveyor belt and carries it into the turret.

The carrier plate is made of iron and is formed into a disk shape, and first to fourth carrier notch grooves to the outer peripheral portion are radially formed.

The cartridge case carried by the carrying belt conveyor is carried into the carrying notch groove in the turret. When the turret rotates, the turret vertically changes the direction of the cartridge case that has been horizontally carried into the notch for transportation. The cartridge case whose direction has been changed is carried out by dropping from the notch groove for carrying.

Further, the turret is provided with a torque limiter for detecting the torque of the turret, and when the turret is overloaded, the torque limiter stops the rotating operation of the turret. The pedestal is provided corresponding to the notch for transport of the turret, and the cartridge case carried out from the notch for transport of the turret is placed on it.

The stopper member is arranged between the terminal end portion of the conveyor belt conveyor and the turret. The stopper member includes a stopper plate that temporarily holds the cartridge case, an air cylinder that raises and lowers the stopper plate, and an air compressor that supplies air pressure to the air cylinder. The stopper member raises and lowers the stopper plate with respect to the transfer surface of the transfer belt conveyor so as to temporarily hold the transferred cartridge cases and carry them into the transfer notch grooves of the turret one by one.

The cartridge cases may be transported in a state where they are in close contact with each other. As shown in FIG. 7, the cartridge case 2 conveyed in an abnormal state is not accurately conveyed into the notch 57A for conveyance of the turret 57, so that the stopper plate 58A of the stopper member 58 moves upward to cause the turret 57 to move. There is a problem that it is caught between 57 and the stopper plate 58A.

The cartridge case 2 that is caught between the notch 57A for transport of the turret 57 and the stopper plate 58A is overloaded by the rotating turret 57 and the ascending stopper plate 58A. There is a problem in that the main body is cracked (hereinafter referred to as a crack) and is damaged.

Therefore, in order not to damage the caught cartridge case 2, the torque for operating the torque limiter of the turret 57 is set to a small value so that a slight load is applied to the cartridge case 2 when the turret 57 is applied. It is necessary to immediately stop the rotation operation of.

However, in the conventional cartridge case transport system 51, the total weight of the turret 57 is heavy, and it is not realized to set the torque for operating the torque limiter to a small value. Further, in order to prevent an overload from being applied to the caught cartridge case 2, it is necessary to set the rising pressure generated when the stopper plate 58A moves up to be small.

Therefore, the present invention provides a cartridge case transfer system capable of preventing the cartridge case caught between the turret and the stopper member from being damaged when the cartridge case is transferred. To aim.

[0015]

In order to achieve the above-mentioned object, a cartridge case conveying system according to the present invention comprises a conveying means for horizontally conveying a cartridge case in which a cartridge is housed, and a plurality of opening means at an outer peripheral portion.

And a turret for turning the case vertically. Further, this cartridge carrying system is provided between a cradle, which is provided corresponding to the carrying recess of the turret, on which the cartridge case carried out from the carrying recess is placed, and between the terret and the end of the carrying means. And a stopper member that temporarily stops the cartridge case that is moved up and down with respect to the transport surface of the transport means and is loaded into the transport recess of the turret. Further, the stopper member is configured such that when the cartridge case carried in the notch for carrying of the turret is temporarily stopped, the ascending pressure generated by the ascending operation is made smaller than the descending pressure generated at the descending operation.

In the cartridge case transport system according to the present invention configured as described above, since the rising pressure generated when the stopper member temporarily stops the cartridge case is made relatively smaller than the falling pressure, the notch for transporting the turret is formed. When the cartridge case that is carried into the groove is conveyed in an abnormal state, for example, when the cartridge case is meshed between the turret and the stopper member, the load applied to the cartridge case is reduced. ing.
