Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for attaching labels to containers and the like.

In general, labels are often affixed by changing the affixing position depending on the shape of the object to be affixed, such as a container.

(Prior Art) In general, labels are often attached by changing the attachment position depending on the shape of the object to be attached, such as a bottle.

In the conventional method, this position setting method is as follows.
For example, the label sticking position can be set based on the distance between the label sticking machine that sticks the label and a sensor such as a photoelectric switch that detects the position of the object to be pasted, and the label pasting position can be determined based on the output signal from the sensor. The following is an example of a device that applies labels using a machine.

As shown in FIG. 6A, the label pasting machine 201 is fixed, and the distance L between the sensors 205 is adjusted by moving the position of the sensor 205 in accordance with the label pasting position 203. That is, when the tip of the object a passes the sensor 205, the label pasting machine 201 is activated to extend the label 207 toward the object a, and the sensor 205 is moved to adjust the distance L. By changing , the position at which the label 207 is attached to the object a is changed.

As shown in FIG. 6B, the sensor 205 is fixed, and the labeling machine 201 is moved in accordance with the labeling position 203 to adjust the interval L. That is, the tip of the adherend a is the sensor 20.
5, the label pasting machine 201 is activated to form the label 207 so as to extend toward the object a, and by moving the label pasting machine 201 and changing the interval L, Change the pasting position of the label 207 in a.

As shown in FIG. 6C, both the sensor 205 and the labeling machine 201 are fixed, and a timer circuit 209 is used to utilize the time delay of the timer circuit 209 after the sensor 205 detects the object a. Then, the label sticking position 203 is adjusted, that is, when the sensor 205 detects the tip of the object a, the timer circuit 209 is turned on, and for example, a time corresponding to the distance from the sticking position 203 has elapsed. After that, the label pasting machine 201 is driven, and the label 2
07.

(Problems to be Solved by the Invention) However, in this method of adjusting the set position, it is necessary to move the labeling machine and sensor many times or operate a timer circuit until the predetermined position is found. Therefore, in order to affix the label at the optimal position, it is necessary to affix the label several times depending on the size of the label, the transport time (amount), and the size and transport time (amount) of the object to be affixed. This was an extremely difficult task that required repeated testing. Moreover, if there is a change in the shape of the object or the label, it must be changed each time, and the accuracy of the position of the label is also poor.

Therefore, the main object of the present invention is to numerically process the control of the label pasting position using the input means, so that the label can be pasted accurately at a predetermined position. Therefore, by simply changing or selecting data, you can easily change the type of object to be affixed, such as a variety of existing bottles, and the label affixing position can significantly reduce the time required to replace labels, etc. We aim to provide the following.
