Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attaching device for attaching a label to a container, which receives a label formed by punching a strip-shaped sheet with a rotary cutter and attaches it to a container moved by a star wheel device. .

[0002]

2. Description of the Related Art A conventional labeling device is shown in FIG.
As shown in 0, the container B conveyed by the conveyor device 1 is introduced into the star wheel device 3 via the timing screw device 2. Then, the strip-shaped label sheet 6 fed from the original fabric 4 by the feed roller 5 is introduced into the rotary cutter device 11 including the cutter drum 9 and the label supply rotor 10 via the step roll 7 and the registration roller 8, and the strip-shaped label sheet 6 is introduced. Punch the label from. Then, the label R held by the label supply rotor 10 is brought into contact with and adhered to the container B moved by the star wheel device 3 according to the rotation thereof. Further, the container B sent out from the star wheel device 3 is introduced into the label pressure bonding device 12, and the pair of belts 1
The label R is adhered to the container B by being sandwiched between the pressure-bonding sponges 14 attached to the sheet 3. Reference numeral 15 is a take-up reel for winding the remaining part of the strip-shaped label sheet 6.

[0003]

In the above-mentioned structure, the label R in the label supply rotor 10 is held by the vacuum load on the attachment / detachment hole, and the label B is delivered to the container B by compressed air. It is carried out by loading.

By the way, the stamping of the strip-shaped label sheet 6 is performed at a narrow pitch at a high speed, whereas the container can not be conveyed by the star wheel device 3 so fast. When the label is transferred from the label holding rotor 10 to the container B, a difference occurs in the moving speed of B, the difference in the speed of the compressed air load switching, the deformation of the container B, the change in the posture, and the moving speed. There were cases where the label sticking position was misaligned due to other factors such as increase and decrease.

An object of the present invention is to solve the above problems and to provide a label sticking device capable of sticking labels punched at a narrow pitch to a container without displacement.

[0006]

In order to solve the above problems, a label sticking apparatus of the present invention comprises a label feeding rotor for feeding a label formed by cutting a strip-shaped label sheet while holding the label on the outer peripheral portion. A label receiving device capable of holding a label on the outer circumference between the container transferred by the container moving device and the label reversing sticking rotor for sticking the label in the vicinity of the container transferred by the container moving device. A pitch adjustment rotor is provided that is arranged so that the segments can move in the circumferential direction.The label adjustment segment is moved forward in the rotational direction at the label reception position from the label supply rotor to change the rotational peripheral speed of the label reception segment. In addition to accelerating, the label receiving segment moves backward in the rotation direction at the label passing position to reduce the rotational peripheral speed of the label receiving segment. It is provided with a grayed adjusting means.

[0007] Further, another pasting device is provided between a label feeding rotor for feeding a label formed by cutting a strip-shaped label sheet while holding it on an outer peripheral portion and a container transferred by a container moving device, or a container moving device. Between the label reversal sticking rotor that sticks the label close to the container transferred by the device, a pitch adjustment rotor that has a label receiving segment that can hold the label on the outer periphery movably arranged in the radial direction of rotation. In this pitch adjusting rotor, the label receiving segment is moved to the outer peripheral side in the radial direction at the label receiving position from the label supplying rotor to accelerate the rotational peripheral speed of the label receiving segment, and the label receiving segment is radiused at the label passing position. It is provided with timing adjusting means for moving the label receiving segment to the inner peripheral side in the direction to reduce the rotational peripheral speed of the label receiving segment.

Further, the timing adjusting means of the first means or the second means is connected to the speed adjusting cam guide portion formed around the rotation axis and the label receiving segment. The cam follower is guided by the speed adjusting cam guide portion.

[0009]

In the above structure, the label receiving segment is moved in the circumferential direction or the radial direction of rotation between the label feeding rotor and the container moving device, or between the label feeding rotor and the label reversal sticking rotor by the timing adjusting means. Since the peripheral speed of the segment is accelerated or decelerated to receive and deliver the label in synchronization with the label supply speed of the label supply rotor and the label transfer speed or the container transfer speed of the label reversal sticking rotor, the label punching is performed. Even if the forming pitch and the label sticking pitch are different, the label can be delivered or stuck while moving in synchronization with the label receiving segment, and the label punched at a narrow pitch can be stuck to the container without misalignment. it can.

By configuring the timing adjusting means with the speed adjusting cam guide portion and the speed adjusting cam follower, accurate acceleration and deceleration can be realized with a simple structure.
