JPH0676108B2 - Capor status detection device for caps capped on bottles - Google Patents

Description

TECHNICAL FIELD The present invention relates to a capped state detecting device for a cap, particularly for detecting a capped state of a cap capped on a bottle containing a drink agent.

"Prior art" To cap a drink agent-containing bottle, first cap the mouth of the bottle, and in this state, press the peripheral wall of the cap from the surroundings with a capping device to transform the peripheral wall into a spiral groove of the bottle. It is done by pushing.

However, if the crowning device is also continuously used for a long period of time, the crowning cannot be reliably performed due to wear of the pressing portion or the like. For example, if the force that presses the peripheral wall of the cap is weak, when a person who purchases this drink rotates it to remove the cap, it will spin around and there is no resistance with the bottle, It will not be possible to separate it from the perforations after a long time. For this reason, it is necessary to check the capped state of the cap by a random inspection. Further, by this, the life of the pressing portion of the crowned device can be checked.

As described above, it is extremely important to check the capped state of the cap capped on the bottle, but in the past, there was no device capable of automatically and efficiently performing this.

"Problems to be solved by the invention" The present invention has been made in view of the above points, and it is possible to automatically and efficiently and accurately check the capped state of the cap capped on the bottle, Moreover, it is an object of the present invention to provide a cap crowned state detection device capable of detecting regardless of the size of the cap.

"Means for Solving the Problem" Therefore, the gist of the present invention is to open and close a pair of clamp tools at a predetermined timing with an air cylinder and a link so that a bottle can be clamped on the base plate. A bottle clamp device that sets a bottle in a stationary state on a bottle holder, an elevating means that elevates and lowers an elevating and lowering support plate at a predetermined timing, and a vertically mounted and vertically rotatably supported bearing through a bearing A torque sensor, and a torque sensor rotation motor that is vertically fixed to the elevating and lowering support plate and rotates the torque sensor at a predetermined speed via a gear or the like,
It is attached to the lower surface of a supporting plate connected to the shaft of the torque sensor, opens and closes at a predetermined timing by an air cylinder and a link, and each end of which has a substantially drum-shaped roller rotatably supported in the vertical direction. And a capped state detecting device for a cap capped on a bottle, which comprises a pair of chucking tools.

"Operation" Next, the operation of the present invention will be described.

First, the bottle clamp device immobilizes the bottle in a fixed position. This is because when the bottle is placed on the bottle holder on the base plate, the air cylinder operates, and when its piston rod extends, a pair of clamps are closed via a link, and this clamp clamps the bottle. Done by.

Next, the lifting motor operates to lower the lifting support plate.
This is because when a vertically fixed lifting motor operates to rotate its rotary shaft, a screw rod connected to the rotary shaft rotates,
A member having a groove provided at the center for fitting with the screw of the screw rod,
It descends along the screw rod, and thus descends the lifting support plate. The elevating and lowering support plate is regulated via a guide so as not to rotate in the horizontal direction but to move only up and down.

Next, with the lowering of the elevating and lowering support plate, the pair of chucking tools in the open state descend.

When the pair of chucking tools descends to the upper end of the bottle cap set on the bottle placing table on the base plate, the lifting motor stops operating, and at the same time, the air cylinder for opening and closing the pair of chucking tools. Works. When the air cylinder operates and the piston rod retracts, the pair of chucking tools are closed via the link, and the upper ends of the caps are clamped by the respective tips with appropriate pressure. Further, at this time, a roller rotatably supported in the vertical direction at the tip of each chucking tool comes into contact with the cap. The roller has a substantially drum shape, and a rubber lining is stretched if necessary.

Next, the torque sensor rotation motor fixed vertically to the elevating support plate operates to slowly rotate the torque sensor vertically supported on the elevating support plate at a predetermined speed.

This rotation is performed by a spur gear fixed to the rotation shaft of the torque sensor rotation motor, and a reduction spur gear fixed to the torque sensor rotatably supported by the support plate via a bearing, which meshes with the gear. Be seen.

Then, when the torque sensor rotates, the shaft is connected to the support plate that supports the chucking tool, so the rotational torque of the cap is measured by the torque sensor,
The torque value is displayed on the attached torque amplifier. And again, this checks the capped condition of the cap.

Even after measuring the torque value in this way, the torque sensor rotation motor continues to operate, and the cap is rotated 2-3 times to remove it from the bottle mouth.

At this time, since the roller of the chucking tool rotates in the vertical direction, when the roller rotates in the horizontal direction, the cap moves vertically along the spiral groove of the bottle mouth and is removed.

When the cap is removed in this way, the lifting motor is then activated again to raise the chucking tool. At this time, the torque sensor rotation motor stops operating.

When the chucking tool finishes rising, the air cylinder operates to advance the cap catcher that receives the cap to a position directly below the chucking tool.

At this time, the air cylinder operates to extend the piston rod again to open the pair of chucking tools and drop the cap held by the chucking tools into the cap catcher.

Then, the dropped cap is accommodated in the cap bucket arranged below the cap catcher.

Finally, the torque sensor rotation motor is reversely rotated to unwind the wound state of the air tube of the air cylinder for opening and closing the chucking tool.

This completes all the steps.
