Description

  The present invention relates to an article direction changing apparatus for changing the direction of an article conveyed by a conveying means.

The necessity to change the direction of the article being conveyed by the conveying means arises for various reasons. For example, when collecting and reusing a resin case used in the distribution process, the cleaning solution is transferred from both sides of the transfer path to both sides of the resin case while the collected resin case is transferred by the transfer means. When adopting a cleaning form that peels and cleans dirt such as affixed labels by spraying, it is necessary to change the direction of the resin case 90 degrees in the middle of the transport path to clean all sides. (See Patent Document 1).

Regarding the direction changing technique of this kind of article, there is known a technique for changing the direction by pushing the rear side surface of the article being conveyed at the tip of a bar-like member configured to be able to protrude by an air cylinder (patent) Reference 2). However, in the case of this technical means, there is a technical problem that not only the directionality is unstable and the direction changing operation varies, but also the article is easily damaged. Furthermore, in order to adjust the reaction when the rear side surface of the article being conveyed is pushed by the tip of the rod-like member, there is a technical difficulty that it is necessary to wind rubber around the conveyance roller. In addition, a contact member that contacts the article is installed on one side of the conveying means, and a curved guide plate is rotated on the downstream side by an air cylinder on the other side opposite to the contact member. It is known that the front end of the article being installed and conveyed is in contact with the abutting member and starts rotating, and the direction is changed while being guided by the swing of the guide plate (Patent Document). 3). However, in the case of this technical means, since the direction change is gradually performed along the guide plate, in order to avoid the situation that the distance required for the direction change becomes long or the article is caught by the guide plate and stopped, There is a technical difficulty in that the guide plate needs to be rotated back and forth around a downstream fulcrum by an air cylinder or the like. Further, contact members whose front end portions contact the front or rear surface of the article are arranged on both sides of the conveying means, and the front end and the rear surface of the article are slid on the front and rear surfaces of the article, What changes direction is known (see Patent Document 4). However, in the case of this technical means, there is a problem that it is difficult to apply when the side surface of the article has irregularities like the resin case.

In addition, a contact member that can be moved up and down while rotating in the horizontal direction is disposed above the transport means. When the contact member is lowered, the front portion of the article to be transported is pressed while being pressed by the locking member. There is known a technique that changes the direction of an article by the cooperative action of an abutting member that abuts against the front part and an abutting member that abuts against the front part of the article and a locking member that engages with the rear part (Patent Document 5). reference). However, in the case of this technical means, a mechanism for moving up and down while rotating the contact member in the horizontal direction becomes complicated, and a locking member that presses the rear part of the article is installed on the conveying means. In addition, there is a technical problem that it is difficult to convert an article from a landscape orientation to a portrait orientation. In addition, the substantially cross-shaped blade body is set in a rotatable state so as to cross the transport path in the horizontal direction, and the article transported on the transport path is fitted in one corner of the blade body. It is known that an article is configured to change its direction by pushing and turning (see Patent Document 6). However, this technical means employs a mechanism in which the substantially cross-shaped wing body is passively rotated by the advancing force of the article, so that the wing body rotates smoothly and the direction changing function functions well. As to whether or not it can be performed, there is a technical problem that the influence of the conveyance state of the article is large and the operation state is restricted. Furthermore, it is difficult to cope with the case where the direction changing function is stopped and the article is simply passed without changing direction.

As described above, if the position and the tilt state of the rotary pusher member can be adjusted by adjusting the front and rear position, the tilted state, the height position, and the like of the rotating shaft, the adjustment according to the article is possible. Further, if the position and the inclination state of the rotation shaft with respect to the conveyance direction can be adjusted, the operation range of the rotary pusher member can be adjusted along the conveyance direction. Furthermore, it is possible to adjust the operating speed of the rotary pusher member via the rotational speed control of the rotary shaft. Note that the axial length of the rotating shaft can be set appropriately depending on the case. The timing for rotating the rotary pushing member is the time when the arrival state of the article is detected by the detection means. As this detection means, a non-contact type sensor such as a proximity sensor or a light projecting / receiving type is suitable. Incidentally, when the direction changing device is disposed in the cleaning chamber, the detecting means may be installed outside the room so that dirt or the like blown up to the detecting means does not adhere to cause malfunction.
