[0002]

2. Description of the Related Art A conventional labeler for attaching a heat-sensitive label to a container or the like cuts the label into a predetermined size and then holds the adhesive surface by sucking the adhesive surface into a suction hole of a suction drum. Print the necessary items on the surface, then check the printing,
After removing the defective label, the printed surface is sucked into the suction hole of the sticking drum, and the glue surface and the printed surface are reversed and held.
The glue surface on the outside was activated and attached to a container or the like.
Labels come in various sizes depending on the purpose of use. Therefore, when adsorbing the label with the labeling drum,
The suction holes need to be covered with a label. Although the suction hole is formed from a group of holes in which several holes are arranged, if there is a suction hole that is not covered with the label, the pressure will not be reduced and the label cannot be sucked. For this reason, at present, a plurality of sticking drums provided with a group of suction holes corresponding to the dimensions of the label are prepared, and if the size of the label changes, the sticking drum of the labeler is replaced at present.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A label sticking drum of a labeler has a suction hole for adsorbing a label on a circumferential side surface. The suction holes are distributed in an area corresponding to the size of the label to be sucked, and each suction hole is connected to an air passage extending in the axial direction of the drum, and the air passage is connected to a pressure reducing device. The label supplied to the sticking drum is sucked by covering the suction hole, passes through the heating activation zone by rotation of the drum, and is pressed and stuck to the sticking object. According to the present invention, one end of the sticking drum is opened to the top surface of the drum, and the other end is provided with a ventilation path connected to the decompression device.The ventilation path is connected to the suction hole. Unnecessary suction holes that do not suck the label among the suction holes connected to the ventilation path by inserting the closing rod are closed, and the suction holes are adjusted to a distribution suitable for the label. By blocking unnecessary suction holes in this way, it is possible to apply a label of any size with a single sticking drum having suction holes distributed in a suction area corresponding to the label having the largest area. Can be. In the present invention, unnecessary closing of the suction hole can be performed in a state where the sticking drum is arranged on the labeler, and thus there is no need to remove the drum. It is preferable that the closing rod has a head protruding outside from the air passage opening on the top surface for convenience of insertion and withdrawal,
Preferably, the length reaches the lowermost suction hole.

As the closing rod, a number of rods having a length corresponding to the distance between the top surface of the drum and each suction hole may be prepared, and the length of the rod reaching the lowermost suction hole may be inserted. It is also possible to provide an adjusting portion and make up with one kind of closing rod. An adjusting hole is provided in accordance with the distance between the suction hole and the top surface of the drum, and the length of insertion is adjusted by inserting a stop pin into this hole so that each of the suction holes is closed with one rod. Alternatively, the ventilation path and the closing rod may be screwed together to adjust the insertion distance. For convenience of explanation, it has been described that an air passage opening for inserting a closing rod is provided on the top surface of the sticking drum. However, an air passage opening is provided on a surface opposite to the top surface of the sticking drum, and the closing rod is inserted from this surface. Alternatively, the closing rod may be inserted from both sides provided on both sides. The closing rod is inserted into the ventilation path from the opening of the ventilation path.However, when the sticking drum is operated, the force for extracting the closing rod does not act, so the diameter of the rod is made slightly smaller than the diameter of the opening of the ventilation path and the diameter of the ventilation path to reduce contact friction. By making it larger, it can be locked only by dropping. Of course, a fixing means such as an air passage opening and a screw may be used. Since the air passage opening is provided on the top surface of the drum in this manner, when the closing rod is inserted, the head of the closing rod does not protrude to the peripheral surface of the drum where the suction hole is arranged, so that there is an advantage that the label suction surface is not affected at all. is there. When the suction hole is closed by inserting a closing rod on the peripheral surface of the sticking drum, the peripheral surface of the drum becomes uneven, which not only adversely affects the pressure contact between the container and the label, but also causes the centrifugal force to act due to the rotation of the drum and the suction hole. Since it escapes from the surface, fixing is required, which is not preferable.
