Description

Detailed Description of the Invention Kui〉Object of the Invention [Field of Industrial Application] The present invention relates to the structure of a labeling machine that continuously supplies a plurality of label rolls to affix labels to objects such as containers. It is something.

[Prior art] In contrast to the type of labeling machine that feeds single labels that have already been cut one by one and affixes them to containers, a labeling machine that draws out uncut labels wound into a roll and cuts them immediately before pasting There is a type of labeling machine that is attached to containers.

[Problems to be Solved by the Present Invention] The following problems exist in the labeling machine that uses the roll-shaped label described above.

(1) Even though it is called a roll, the length is finite, so if a roll is consumed, a new roll must be supplied.

However, when replenishing rolls, the operation of the labeling machine must be stopped every time the rolls are replaced.

(2) Recent labeling machines aim to increase speed, and devices that can apply 600 to 1,000 zero labels per minute have been developed, which greatly reduces the consumption time of label rolls. That will happen.

As a result, the amount of label roll replenishment time taken up by label pasting has a significant impact on processing efficiency, potentially rendering high-speed processing meaningless.

[Objective of the present invention] The present invention has been made in view of the above points, and is capable of achieving high efficiency by using roll-shaped label tape and without stopping the operation of the device every time the roll-shaped label tape is replenished. The purpose is to provide a labeling machine that can perform continuous processing.

〉Configuration of the Invention [Means for Solving the Problems] Each part of the labeling machine of the present invention will be described below with reference to the drawings.

(1) For the coarse label tape supply section In Figure 1, 1 is a roll stand, 2 is a tension roller,
3 is a pull-out roller, 4 is a cutter, 5 is a suction drum, 6
7 is a drum for pasting, and 7 is a drum for gluing.

Then, the roll-shaped label tape T on the roll stand 1 that is pulled out between a set of pull-out rollers 3 is cut into one predetermined label size with a cutter 4, and placed on the conveyor 9 one by one with a suction drum 5. The structure for attaching it to the container 10 is known.

(2) Second coarse label tape supply section In the present invention, a second coarse label tape supply section is further provided.

That is, in parallel with the coarse label supply section, a second roll table 1-1, a second tension roller 2', a second pull-out roller 3', a second cutter 4', and a second suction drum 5- are installed.
1. A drum 6-1 for second gluing and a drum 7' for second gluing are installed to form a second label tape supply section.

In this embodiment, the second coarse label tape supply section is located on the upstream side of the conveyor 9 with respect to the -th coarse label tape supply section, but the two may be arranged in reverse.

(3) Termination detection device A termination detection device 8 is provided in each label supply section. - This end detection device 8 is a device that is placed in the middle of transport before the label tape T is cut, and is a device for the purpose of detecting the end of the label tape T.

As the end detection device 8, for example, a known phototube is used, and while the label tape T is present and vibrating, it is reflected on the tape surface to confirm its presence, and when the label tape T passing in front of the phototube disappears. When the reflected light can no longer be detected, it can be configured so that it can be output as a signal for passing the end of the label tape T.

The signal that detects the end of the label tape T acts as a signal to start operation of other standby label tape supply units, and also acts as a signal to stop the operation of the label tape supply unit that has detected the end of the label tape T. Configure it so that it also works.

Other methods for detecting the end of the label tape T include a method in which a phototube checks the end display displayed near the end of the label tape T in advance and sends a predetermined signal, or a movable method. A method in which a switch is provided on the tension roller, and the switch detects the displacement of the tension roller that occurs when the finger pressure on the label tape T is released, and sends it as a signal to detect the end of the label tape ■, or a method in which the tape is placed in line of sight while the tape is being held. A light emitter and a light receiver are installed in the , and when the tape T decreases beyond a certain level, the light from the emitter passes through the side of the tape T and reaches the receiver, or whether or not there is repulsion of the compressed air blown onto the tape T. It is also possible to adopt a method for distinguishing.

Next, a method for replenishing rolls will be explained.

(1) Switching from the first coarse label tape supply section to the second coarse label tape supply section When the label tape T on the roll stand 1 is pulled out and finished, the vicinity of the end of the tape T is in front of the end detection device 8. pass through.

The signal detected by the end detection device 8 is input to the second suction drum 5' and the second attachment drum 6-, and, for example, an electromagnetic clutch is engaged to start rotation.

At the same time, the second pull-out roller 3', second cutter 4, etc. also start operating.

As a result, the waiting tape T is pulled out from the second roll table 1-.

After the label tape T is cut by the second cutter 4', the label is attached by contacting the container 10 approaching by the conveyor 9 via the suction drum 5' and the drum 6'.

Further, the operation of the label tape supply unit when the end of the label tape T is detected is controlled by the detection signal from the end detection device 8.
The operations of the pull-out roller 3, cutter 4, suction drum 5, pasting drum 6, etc. are stopped all at once or sequentially.

A new roll is supplied onto the roll stand 1 of the stopped tape supply section, preparations are made for the next pasting operation, and the tape is placed on standby.

As described above, the tape T from one label tape supply section is
When the supply of label tapes is completed, the operation is automatically stopped, and at the same time, the standby label tape supply unit starts operation, so switching can be carried out smoothly without missing a single tape.

(2) Switching from the second supply section to the second supply section When the tape T supplied in the second supply section is consumed and the end is detected by the end detection device 8 in the second supply section, the second supply section In the same way as when switching from the tape T to the second supply section, the operation of the supply section that detected the end, that is, the second supply section, stops, and at the same time, the operation of the waiting supply section starts and the tape T is smoothly transferred. It should be noted that adjustment of the connection position between the running tape T and the waiting tape T is easy since the rotational speed and label size and pattern are constant.

<C> Effects Since the present invention is as explained above, the following effects can be expected.

(1) When multiple sets of label tape supply units are arranged and the end of the tape being supplied is detected, the operation of the label tape supply unit of the set in which the end was detected is stopped, and at the same time, the standby label tape supply unit starts operation. This allows for smooth switching without stopping the device each time the roll is replenished, making it possible to supply tape continuously for hours.

Therefore, since the high-speed processing of the labeling machine can be fully followed, the original performance of the apparatus can be demonstrated, and the processing efficiency is greatly improved.

(2) Even if the tape is torn while it is being transferred, the waiting supply unit will automatically start operating.
Continuous supply is possible without label defects.
