Abstract

PURPOSE:To carry out positioning with high accuracy and high efficiency by transporting a container in a transverse condition with a conveyer, and rotating the container synchronouly with the traveling of the container to position in a circumferential direction when positioning a cylindrical container in the circumferential direction for applying a label and so on. CONSTITUTION:A container 1 is laid transversely to be supported with a guide bar 2, and transported by back-pushing with a hook 3 which travels with a chain 6. Besides, if the container 1 passes through the prescribed position of a positioning part 5, a positioning signal is outputted, a rotating body 11 travels synchronously with the traveling of the container 1 by the action of a cam shaft 16 and the positioning hook 36, and also an oscillating arm is oscillated in an arrowed direction to push the rotating body 11 to the container 1. Next, the rotating body 11 is rotated in an arrowed direction, and the container 1 is rotated in a direction indicated by (e) in the figure. Moreover, the container 1 is rotated until a sensor not illustrated here detects marks on the container, for positioning.

Description

Detailed Description of the Invention (Industrial Application Field) This invention relates to a method for positioning a container in the circumferential direction when cylindrical containers are continuously transported on their side and a label is attached to a predetermined position on the container. .

(Prior Art) As described above, when a cylindrical container is transported on its side and the container is positioned in the circumferential direction, the container has conventionally been positioned manually. Since this is done by an operator, the positioning accuracy is poor (and the efficiency is also poor, so there is a problem that the capabilities of high-efficiency automatic labelers etc. cannot be fully utilized).

(Problems to be Solved by the Invention) The present invention enables accurate and highly efficient positioning of a cylindrical container in the circumferential direction in a method for positioning a cylindrical container connected to a high-efficiency automatic labeler as described above. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the present invention conveys a container on its side on a guide, presses the container in synchronization with the movement of the container, and rotates the container. It is characterized by positioning in the circumferential direction.

(Function) In the method for positioning a container according to the present invention, the container is conveyed on its side while being pressed and rotated in synchronization with the movement of the container. It becomes possible to perform directional positioning.

(Example) An example of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a cross-sectional perspective view of a positioning part of an apparatus embodying the container positioning method according to the present invention, and numeral 1 indicates a cylindrical container.

The cylindrical container 1 is, for example, a plastic container in which a lotion is sealed. In recent years, patterns have been directly printed on such plastic containers 1, and when pasting labels etc., it is necessary to position the containers 1 with high accuracy. In addition to (hereinafter referred to as container 1), any cylindrical object such as a glass bottle or can that requires positioning in the circumferential direction can be used.

The containers 1 are fed one by one onto the conveyor 4 in a horizontal manner, and are conveyed by the conveyor 4 in the direction of arrow A and pass through the positioning section 5, so that the predetermined positioning in the circumferential direction can be performed with high precision. It is carried out with high efficiency and is sent out in time to the next process, such as a highly efficient automatic labeler.

The transport conveyor 4 transports the container 1 in a horizontal manner, and is equipped with two guide bars 2.2 and hooks 3.3, which are hung in an endless manner. They are provided at predetermined intervals on the passed chain 6, protrude in the middle of the guide bar 2.2, and abut against the rear end of the container l placed on its side on the guide bar 2.2. transport. The chain 6 is continuously driven as appropriate by a drive device (not shown).

The two guide bars 2.2 allow the container 1 to be placed on its side and slid on the same bar 2.2, and the container 1 is rotated in the positioning section 5, so that a long bar can be placed on the container 2.2. However, it is preferable that the portion corresponding to the positioning portion 5 is divided in the length direction to form a rotatable bar. In this case, the guide bar may be divided into any number of parts in the length direction, as long as the container 1 can be slid in the length direction. Further, the divided portions may be driven as one unit, but it is desirable that the driving method in this case be performed in synchronization with the rotating body 11, which will be described later.

The hooks 3 , 3 are guided by guides 8 . 8 . 8 . 8 . 8 . 8 . The container 1 is conveyed by contacting the rear end.

The rotating body 11 may be in the form of a pulley or a roller, but in synchronization with the movement of the container 1, the container 1 is moved by the guide bar 2.

When the hook 3 that conveys the container 1 passes a predetermined position of the positioning section 5, a positioning signal is transmitted, the camshaft 16 rotates, the positioning hook 36 is activated, and the rotating body 11 moves in synchronization with the container 1. The swing arm 12 swings in the direction of the arrow, and the rotating body 11 presses the container 1. At the same time, the rotating body 11
rotates in the direction of the arrow 2 to rotate the container 1 in the direction of the arrow E, and the sensor 44 detects a predetermined mark on the container 1 and rotates the container 1 to a position to be positioned. This completes the positioning of the container l. Alternatively, the positioning of the container 1 may be completed by stopping at the position where the sensor 44 detects a predetermined mark on the container 1.

Next, a clutch (not shown) operates and the timing belt 31
rotates, the rotating body 11 moves in the direction of the arrow opening and returns to a predetermined position, the clutch is released, and the rotating body 11 waits at that position.

As described above, while the container l is being transported on the transport conveyor 4, it passes through the positioning section 5, thereby being positioned at a predetermined position in the circumferential direction, and then sent to the next process.
