Description

Detailed Description of the Invention The present invention provides a labeling machine that continuously supplies a plurality of label tapes, cuts the tape pulled out immediately before punching, punches it into a label shape, and affixes the label to a container, etc. It's about structure.

[B] Conventional technology 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. Paste it on the container.

Eve's labeling machine exists.

By the way, if the label is rectangular, it can be easily manufactured by continuously cutting the drawn tape.

However, when the label to be manufactured is oval or other deformed type, a punching method is employed.

In other words, after the tape surface of the drawn tape is punched out using a rotary or reciprocating punching device, the punched labels are transferred to the next process and pasted onto containers, etc., while the remaining tape scraps are removed. It is collected by winding it up on a collection drum, etc.

[Explanation] Problems to be Solved by the Present Invention The labeling machine using the above-mentioned roll-shaped label has the following problems.

(AI) (1) Even though it is called a '0-le, the length 1 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 paste 600 to 1000 zero labels per minute have been developed, which greatly reduces the time consumed by the roll. It turns out.

As a result, the proportion of roll replenishment time taken up by adhesive attachment greatly affects processing efficiency, potentially rendering high-speed processing meaningless.

<Manufacturing of punched labels> (1) When manufacturing labels by continuously punching them out of a long tape, reducing the remaining width between each label will reduce the amount of waste tape generated by punching and improve the tape. can be used effectively.

However, the force for pulling out the tape is generated by pulling the scrap tape after punching, so if the tape punching interval is set to the limit, the tape will be torn off by the winding force, making it impossible to collect the scrap tape.

(2) In order to collect waste tape without breaking it, it is necessary to leave enough width around the punched hole to resist the winding force.

Therefore, from the viewpoint of effective use of tape, this is uneconomical and there is room for improvement.

The present invention has been made in view of the above points, and uses roll-shaped label tape, and continuously processes the roll-shaped label tape with high efficiency without stopping the operation every time the roll-shaped label tape is replenished. - It is an object of the present invention to provide a labeling machine that can reduce the remaining width between punched holes to the bare minimum by adding a cutting process that seems like a waste, and can use tape with excellent economic efficiency.

[Means for solving the box problem] Each part of the labeling machine of the present invention will be explained below with reference to the drawings.

(1) Coarse label tape supply section In Fig. 1, 1 is a roll stand, 2 is a tension roller,
3 is a pull-out roller, 4 is a cutter, 5 is a correction drum, 6
．． 61 is a punching drum, 7 is a gluing (f drum), and 8 is a pasting drum.

Then, after cutting the roll-shaped label tape T sandwiched between a pair of pull-out rollers 3 and pulled out into a size that fits the label size with a cutter 4, the supply timing is corrected with a correction drum 5, and then the punching drum 6.61 The label L is punched out into a predetermined outline between the punching drums 6 and 61, and is collected by the drum 8 and pasted one sheet onto the container 10 on the conveyor 9 approaching from the tangential direction of the drum 8. It has a structure in which labels L are attached one by one.

(2) Second coarse label tape supply product 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 stand 1', a second tension roller 2-1, a second pull-out roller 3-1, a second cutter 4', a second correction drum 5',
A second punching drum 6,', 61', a second gluing drum 7-1, and a second pasting drum 8' 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 Each label supply section is provided with an end detection device 11, respectively.

This end detection device 11 is disposed during transport before the label tape T is cut, and is a device for the purpose of detecting the end of the label tape T or the remaining amount.

As the end detection device 11, for example, a known phototube is used, and while the label tape T is present, it is reflected on the tape surface to confirm the presence, and the label tape T passing in front of this phototube is detected. When it disappears and the incident 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.

Then-C, the signal that detects the end of the label tape T acts as a signal to start operation of the standby label tape supply section, while stopping the operation of the label tape supply section that detected the end of the label tape T. It is configured to also act as a signal.

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 2, and the switch detects the displacement of the tension roller 2 that occurs when the finger pressure on the label tape 1 is released, and sends it as a signal to detect the end of the label tape, or a roll of the label tape T. A method in which a light emitter and a light receiver are installed on a line of sight that sandwich the label tape T, and when the radius of the roll of label tape T decreases by more than a certain level, the light from the light emitter flows up the side of the roll of label tape T and reaches the light receiver. ,
Alternatively, it is also possible to adopt a method of distinguishing by the presence or absence of repulsion of compressed air blown onto the bell tape T.

(4) Correction drum (Fig. 2.3) The correction drum 5 receives a single piece of tape T cut into a predetermined length by the cutter 4, and when it is transferred by suction to its circumferential surface. The purpose of this drum is to correct the supply position and supply it to the next handling drum 6.61 at an accurate timing.

In order to provide the above-mentioned functions to the correction drum 5, for example, a large number of suction holes are provided on the surface of the correction drum 50, and claw bodies 51 are provided on the circumferential surface thereof protruding in the direction of the central axis.

The base end of the communication path connecting to each suction hole is exposed in an open state on the bottom surface of the drum, and furthermore, the base end of the communication path connecting to each suction hole is exposed in an open state on the bottom surface of the drum. A conceivable method is to form a negative pressure groove 52 extending in the direction of the negative pressure groove 52 and to generate negative pressure only in the suction hole passing through the straight line L of the negative pressure groove 52.

In other words, before the single piece reaches the punching drum 6.61, the pressure of the suction hole that was sucking the single piece of tape is cut off, so the claw body 51 catches up with the single piece of tape, and the supply timing of the single piece is reached. It is a structure that corrects.

A guide cover 53 is placed near the circumferential surface of the correction drum 5 to prevent single pieces from flying out.

(5) Punching part The punching part is a punching type that punches out a label L having a predetermined outline from a single piece cut by the cutter 4, or a punch type that reciprocates a known punch or a drum as shown in the drawing. type can be adopted.

In this embodiment, a case where a drum type is adopted will be explained, but two drums having a punching function are simply used, namely, a die drum 6 having a die 62 recessed on its circumferential surface, and a punch 63 protruding from its circumferential surface. The punch drum 61 not only passes a single piece of tape between the circumferential surfaces of the punch drum 61 and punches it into a predetermined label outline shape, but also separates and transfers the punched label L and single piece scraps. be.

That is, the die drum 6 is opened around the die 62 over a section from the tangential position where it receives the single piece supplied from the correction drum 5 to the point where it passes the closest position to the peripheral surface of the punch drum 61. The structure is such that negative pressure is generated in the suction hole 64.

To generate negative pressure in the suction hole 64 over the above section,
Similar to the correction drum 5, it is possible to adopt a method in which a negative pressure groove 65 extending over the above section is provided at the bottom of the die drum 6, and negative pressure is generated in the suction hole 64 only when passing over this negative pressure groove 65. .

Therefore, the die drum 6 can adsorb only a single piece of waste after punching and separate it from the label L.

The punch drum 61 also has a suction hole 66 on the surface of the bonder 63.
is opened, and is configured so that only the label L punched out by shearing with the die drum 6 is adsorbed and transferred to the position closest to the circumferential surface of the drum 8 for pasting.

In order to generate negative pressure in the suction hole 66 on the surface of the punch 63 over the above section, for example, a negative pressure groove 67 that connects this section is formed at the bottom of the punch drum 61, and the passage passes over this negative pressure groove 67. The configuration can be such that negative pressure is generated in the suction hole 66 only when this occurs.

(6) Pasting Drum The pasting drum 8 is a drum for the purpose of receiving the label L punched out at the punching section and pasting it onto the container 10.

In order to transfer the received label L from the punching part until it is attached to the container 10, a suction method using negative pressure or a known transfer method in which the label L is directly gripped and transferred with a picker is adopted. However, in this embodiment, when using adsorption, this will be explained in detail.

That is, for pasting, a large number of suction holes are opened on the circumferential surface of drum 8, and negative pressure grooves are created at the bottom of drum 8 over a section from the position closest to punch drum 61 to contact with container 10. 81, and is configured to generate negative pressure only in the suction hole passing above the negative pressure groove 81.

Note that if the punch drum 61 is provided with a pasting function, the drum 8 can be omitted for this pasting.

Next, the operation of the labeling machine will be explained.

(1) Cutting the tape As shown in FIG. 1, the label tape supply section for the second grain is operated.

At this time, the label tape supply unit for the second tape is loaded with a new roll and placed on standby.

The tape T pulled out by the pull-out roller 3 is transferred to the cutter 4.
Cut the label to the last possible length in the transport direction of the label to be punched.

(2) The single piece cut by the punching cutter 4 is sent to the correction drum 5 to correct its feeding position, and then fed to the punching drum 6.61 where a label L having a predetermined contour is punched out.

At this time, even if the length of the single piece supplied to the punching section is at the limit of the label dimensions, the supply position of the single piece is accurate, so it is possible to manufacture the label L according to the standard without causing any deviation in the punching position. .

(3) Attachment of labels and discharge at the shoulder A single piece of waste is attracted to the die drum 6 and a label L is attracted to the punch drum 61 and separated.

The label L is pasted and transferred to the drum 8, while the single piece of waste is attracted to the die drum 6, transferred, and then released when the negative pressure is cut off.

On the other hand, the label adsorbed to the drum 8 is pasted in contact with the container 10 approaching from the tangential direction of the drum 8.

(4) Switching from the label tape supply section for the first thread to the label tape supply section for the second thread. Labels L are continuously pasted as described above, and the label tape T on the roll table 1 is pulled out. When the end time approaches, the end detection device 11 detects this.

The signal detected by the end detection device 11 is inputted as an operation start signal to the second label tape supply section, which has been on standby, and starts operation.

The operation status is the same as in the first label tape supply section, where the waiting tape T is pulled out from the second roll stand 1'(7'), the label tape T is cut with the second cutter (4-), and then the correction is made. Drum 5-1 Punching drum 6', 61',
In the second affixing, the label L is continuously affixed by contacting the approaching container 10 by the compare 9 via the drum 8'.

In addition, the signal detected by the end detection device 11 is input as an operation stop signal of the first label tape supply section where the end of the label tape T is detected, and the signal is inputted as a stop signal for the first label tape supply section where the end of the label tape T is detected, and the pull-out roller 3, cutter 4, suction drum 5, pasting drum 6, etc. operations stop all at once or one after another.

A new roll is replenished onto the roll stand 1 of the stopped first label tape supply section and kept on standby in preparation for the next changeover.

As described above, the tape T from one label tape supply section is
When the tape supply approaches the end, operation will automatically stop, and at the same time, the standby label tape supply section will start operation.
Switching can be performed smoothly without missing a single tape.

J5. Adjustment of the connection point between the running label tape T and the waiting label tape is easy because the rotational speed and the size and pattern of the label L are constant.

(5) Other Examples In addition to the above-mentioned embodiments, it is possible to paste labels continuously by sharing only the drum, and also to apply continuous labels in the same way with the following combinations. It can be carried out.

<A> Method of sharing parts from the correction drum to the pasting drum (Fig. 4) This pasting method uses the correction drum 5 and the punching drum 6.6.
1, and pasting (butrams 8 are arranged one by one and shared), a roll table 1.1', a tension roller 2.2', and a pull-out roller 3, which are means for supplying single pieces to the correction drum 5. .3', cutter 4.4', etc. are provided, and when one label tape is nearing the end (t
Detecting this, the standby label tape supply means starts operating and is configured to continuously supply the single pieces cut by the cutter 4 to the correction drum 5.

<3> How to share the cutter and pasting drum (
(FIG. 5) This method is a method in which two supply means for supplying the label tape T are arranged and continuously supplied to one cutting section.

That is, two rollers 3.3- are arranged in front of the cutter 4, and the label tapes T pulled out from both pull-out rollers 3.3- are guided to the sides of the horizontal kite board 12 and merged just before the cutter 4. Configure it to do so.

When the end of the label tape T being supplied is detected, the other waiting label tapes start supplying to the cutter 4.
Continuously supply the label tape T to the punched label I.
- is pasted in succession.

Furthermore, when changing the label tapes, it is conceivable to move back the leading edge of the label tape T on the side whose supply has been stopped so that the leading edge of the label tape T on the side whose supply has been stopped is not wound up by the cutter 4.

For example, one way to do this is to blow air (t
Possible methods include bending the tip of the label tape T by bending it, or pressing a rod or the like against it to cause the tip of the label tape T to retreat.

[2] 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, the high-speed processing of the labeling machine can be sufficiently followed, so that the original characteristics of the device can be exhibited, and the processing efficiency can be 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.

(3) Since the tape is cut immediately before punching, there is no need to worry about the remaining width of the tape in the transport direction in order to collect waste tape, unlike in conventional punching.

Therefore, since the punching interval can be set to the very limit, the tape can be used effectively, which is economical.

(4) The punched waste tape can be separated from the label and transported for release.

Therefore, post-processing of the waste tape becomes easy.
