Description

  The present invention relates to a plug direction control device applied to control the direction of a plug or a container or both when a certain directionality is required between the container and the plug.

  When the liquid in the container is poured out by tilting the container, the inner cap and the cap having the spout need to be plugged so as to face a specific direction with respect to the container.

  For this reason, it is necessary to perform capping after positioning the cap to always face the same direction with respect to the direction of the container supplied in a certain direction. A capper provided with a device for positioning the cap is already known so that the cap can always be plugged in the same direction with respect to the containers aligned in a certain direction as described above (for example, Patent Document 1). Or refer to Patent Document 2.)

  In the cap positioning device provided in the capper described in Patent Document 1, a pocket for receiving an inner plug supplied in a random direction is formed on the outer peripheral portion. A positioning rotor that rotates intermittently and a pocket passing position of the positioning rotor are disposed. Engage from above the inner part of the rotary head that can be moved up and down to engage the inner plug fitted in the pocket and rotate the inner plug, and the recess formed on the bottom surface of the inner plug rotated by the rotary head. And an up and down engaging pin for positioning the cap.

  In the cap positioning device, the engaging pin rises from below and contacts the lower surface of the spout, and at the same time, the rotating head descends from above to press the inner plug and rotate it by frictional force. When the inner plug rotates and the engaging pin engages with the recess formed on the lower surface of the spout, the inner plug is prevented from rotating by the engaging pin, and the spout of the inner plug is aligned at a certain position. It has become.

  Further, the positioned inner plug is supplied to the main rotary by the cap supply rotor. The inner plug is gripped by the plugging head disposed on the main rotary so as to be movable up and down.

  Further, during the rotation of the main rotary, the stopper head holding the inner stopper aligned in the predetermined direction is lowered by the cam and the inner stopper is driven into the opening of the body located below. . Thereby, the spout can be plugged into the bottle with the spouts aligned in a certain direction.

  Further, a capper described in Patent Document 2 is fixed to a spindle, a driving side rotating part connected to a driving system such as a driving motor, a spindle linked to the driving side rotating part via a clutch mechanism, and the spindle. A direction regulating device comprising a direction regulating plate and a stopper. Then, the caps supplied in an aligned state via the cap sorter are gripped by matching the orientation of the chuck portion attached to the spindle.

  Furthermore, the direction regulating device that regulates the direction of the article by rolling the article by contact friction between the surface of the article and the surface of the friction means and bringing the engaging portion provided on the article into contact with the stopper member (For example, see Patent Document 3) is also known.

The device is a direction regulating device in which the friction means is constituted by a friction belt stretched between free wheels, and a brake means for applying an appropriate braking force to rotation of the free wheel is provided. Yes.

  For this reason, after the engagement portion of the article abuts against the stopper member and the rotation is prevented, the free wheel causes the braking force by the contact friction force between the surface of the article and the friction surface of the friction belt. Since it overcomes the above and starts rotating, relative sliding on the contact surface between the surface of the article and the friction surface of the friction belt can be avoided, so that it is possible to prevent the surface of the article from being scratched or blurred. It is described.

  By the way, in the capper of Patent Document 1, the cap positioned in the inner plug positioning portion is delivered to the plugging head via the cap supply rotor while being positioned and plugged. For this reason, devices such as a positioning rotor and a cap supply rotor are required, and there is a problem that the entire capper is complicated and large, and the number of processes increases.

  In addition, the chuck direction regulating device for the capper disclosed in Patent Document 2 matches the direction of the chuck with the direction of the cap supplied in a state of being aligned in advance by the cap sorter, and does not regulate the direction of the cap itself. . In addition, there is a problem that the caps must be aligned in the same direction in the cap sorter or the stout.

  Further, in the direction regulating device of Patent Document 3, the friction belt is used to roll the engagement portion provided on the article so as to contact the stopper member. For this reason, there is a problem in that the frictional force varies depending on the outer peripheral shape and material of the article, and the friction belt or the like must be adjusted when the article is switched.

  Furthermore, it takes time to adjust the frictional force between the friction belt and the article. And there exists a problem that positioning accuracy is low and it is unstable, such as the engagement part provided in the article depending on the adjustment result comes off from the stopper member or the article does not reach the stopper member.
