Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking system for sticking a main label such as a glue label or a heat-sensitive adhesive label and a sub label such as a tack label to an adherend.

[0002]

2. Description of the Related Art For example, as in a nutritional supplement drink,
For a liquid product in a container filled in a bottle container (hereinafter referred to as a liquid product), as shown in FIG. 8, a glue label in which the product name, efficacy, ingredient, etc. are displayed on the outer peripheral surface of the body of the bottle container B. The main label ML consisting of a heat-sensitive adhesive label and the like is attached so as to be wrapped around it. However, in order to enhance the sales promotion effect, a small tack label with a catch phrase or the like called a "POP label" is attached to the sub-label SL. As a result, it may be separately attached to the bottle container B.

By the way, when such liquid products LG such as nutritional drinks are displayed in stores, the front side thereof, that is, the main label ML on which the product name, characteristic design, etc. are displayed in large size is usually displayed. Since it is arranged on the display shelf so that the central portion faces the front side, when a small sub-label SL such as a POP label is attached to the bottle container B, if it is not attached near the central portion of the main label ML, Sales promotion effect is not demonstrated.

Therefore, in the label sticking system capable of sticking the sub-label SL in addition to the main label ML to the bottle container B or the like, as shown in FIG. 9, a main labeler 51 such as a glue labeler or a heat-sensitive labeler is used. , The liquid product LG such that the central portion of the main label ML faces a certain direction on the downstream side of the transport line 52 of the liquid product LG having the main label ML attached to the outer peripheral surface of the bottle container B or the like.
A positioning device 53 for circumferentially positioning and a sub-labeler 54 such as a tack labeler for sticking the sub-label SL are sequentially installed, and the positioning device 53 performs circumferential positioning on the transport line 52. Sub-labeler 54 for liquid products LG that are sequentially transported
Thus, the sub label SL is attached near the center of the main label ML.

[0005]

However, as described above, if the alignment device 53 of the liquid product LG and the sub-labeler 54 are installed in the middle of the transfer line 52 of the liquid product LG, the entire label sticking system becomes large. The sub-labeler 54 is used only for the process of attaching the sub-label SL, which is not always performed.
Besides, since the alignment device 53 must be installed, there is a problem that the equipment cost of the entire label sticking system becomes high.

[0006] In addition, when an attempt is made to attach the sub-label as described above by using the existing label attaching system which is installed to attach only the main label to the bottle container of the liquid product, etc. The above-mentioned alignment device and sub-labeler must be installed on the liquid product transfer line in the label sticking system, but in many cases it is not possible to secure the space for installing these devices. There is a problem that it is practically difficult to attach sub-labels using the label attaching system of.

[0007] Therefore, an object of the present invention is to provide a label sticking system capable of surely sticking two kinds of labels such as a main label and a sub label at a predetermined position of an adherend with a minimum installation space and equipment cost. To provide a dressing system.

[0008]

Means for Solving the Problems and Effects Thereof In order to solve the above problems, the invention according to claim 1 is a main labeler for sticking a main label of a predetermined length on the outer peripheral surface of the body of an adherend. And a sub-labeler for attaching a sub-label to the surface of the main label, the main labeler,
By rotating the front side of the main label in a state of being suction-held on the outer peripheral surface, the main label is conveyed to the attaching position, and the outer peripheral surface of the body of the adherend conveyed to the attaching position is conveyed. Individual main labels are formed by sequentially cutting the sticking drum that sticks the main label around the adherend while contacting it, and the long strip-shaped main label forming base material that is fed. The main label is provided with a cutting / conveying means for directly or indirectly sequentially delivering to the sticking drum, and the sub-labeler is in the middle of feeding the main label forming substrate to the cutting / conveying means. The present invention provides a label sticking system characterized in that the sub-label is stuck to a predetermined position of a main label forming base material.

As described above, in this label sticking system, the main label forming substrate is sent to the cutting and conveying means of the main labeler for sticking the main label such as the glue label or the heat-sensitive adhesive label to the adherend. Since the sub-label is attached to the predetermined position of the main label forming substrate during feeding, it is only necessary to attach the main label to the adherend, and once the main label is attached to the adherend. Unlike conventional label sticking systems that attach a sub-label separately to an adherend, it is not necessary to install an aligner for the adherend in the middle of the transfer line for the adherend, so label sticking The facility cost of the system can be reduced and the installation space can be minimized.

In order to solve the above problems, the invention according to claim 2 provides a main labeler for sticking a main label of a predetermined length on the outer peripheral surface of the body of an adherend, and a surface of the main label. And a sub-labeler for sticking a sub-label to the main labeler, which conveys the main label to a sticking position by rotating while the front side of the main label is sucked and held on the outer peripheral surface, and the sticker is attached. A sticking drum that sticks the main label while winding it around the sticking body by bringing it into contact with the outer circumferential surface of the sticking body that is conveyed to a position, and the outer surface of the back side of the main label. And a conveying drum that conveys the main label to a transfer position to the attaching drum by rotating in a state of being sucked and held by the sub-labeler to the conveying drum. That in the middle conveying of the main label, there is provided a label sticking system characterized by being adapted to adhere the sub-label to a predetermined position of the main label.

As described above, in this label sticking system, the main label is stuck on the sticker to be adhered with the main label such as the glue label or the heat-sensitive adhesive label while the main label is being conveyed. Since the sub-label is attached to the predetermined position of the above, it is only necessary to attach the main label to the adherend, and once the main label is attached to the adherend, the sub-label is separately attached to the adherend. Unlike the conventional label sticking system that wears, it is not necessary to install a device for aligning the sticker in the middle of the transfer line for the sticker, so the equipment cost of the sticking system can be reduced. It can be done and the installation space can be minimized.

In particular, in order to convey a main label to a sticking drum and to print predetermined information such as expiration date and serial number on the main label, a main labeler such as a glue labeler or a heat sensitive labeler is usually used. A conveyor drum that conveys the main label while suction-holding the outer surface with the label surface facing outward is provided.Predetermined information is provided on the main label by the printing device provided during the conveyance of the main label by the conveyor drum. Since it is designed to print, it is not necessary to provide a separate transport drum just for attaching the sub-label.

Further, at the stage of carrying the main label by the carrying drum, the main label basically passes through the sub-label sticking position at a constant cycle while keeping the main label in a predetermined carrying posture. A sub-labeler such as a tack labeler does not need to install a matching device, but only a commonly-used label sticking timing control is performed to ensure that the sub-label is stuck to a predetermined position on the main label. You can

However, when the sub label is attached to the main label, impact force may be applied to the main label,
The main label sucked and held on the outer peripheral surface of the transport drum may be displaced. Therefore, as in the label sticking system of the invention according to claim 3, at the time of sticking the sub-label to the main label by the sub-labeler, a holding force that enhances the holding force of the main label to the outer peripheral surface of the transport drum. It is desirable to adopt a configuration in which the augmenting means is provided on the main labeler.

It is supposed to be done.

The sub-labeler 40 has a long sub-label forming base material SM, which is preliminarily punched with individual sub-labels SL in a state of being adhered to a release paper, and an outer periphery of a conveying drum 18 which constitutes a label passing means 17. The sheet is intermittently fed near the sub-label sticking position ω set between the first delivery position β and the printing device 19, and the sub-label forming substrate SM is peeled off near the sub-label sticking position ω. The plate is turned upside down at an acute angle to sequentially separate the individual sub-labels SL from the release paper of the sub-label forming substrate SM while passing through the sub-label attachment position ω while being suction-held on the outer peripheral surface of the transport drum 18. It is a normal tack labeler that is sequentially attached to the main label ML, and the long sub-label forming base material SM is a base material roll wound in a roll shape. Fed from Le MR, sublabel forming substrate SM after individual sub-labels SL has been peeled off
Is wound around a take-up reel as a waste roll ER.

Further, a label detection sensor (not shown) for detecting the main label ML is provided on the front side of the sub-label sticking position ω in the transport path of the main label ML by the transport drum 18, and this label is provided. After a predetermined time elapses after the sub-labeler 40 receives the label detection signal output from the detection sensor, the sub-labeler 40 intermittently feeds the sub-label forming base material SM for a predetermined length, thereby the main label ML. The sub-label SL is surely attached to the predetermined position. Therefore,
By appropriately adjusting the feeding timing of the sub-label forming substrate SL by the sub-labeler 40 after receiving the label detection signal, the sub-label SL can be attached to any position in the longitudinal direction of the main label ML.

Further, in the label transfer means 17 constituting the main labeler 10, as shown in FIGS. 2 to 4, at the time when the sub-labeler 40 attaches the sub-label SL to the main label ML, A holding force increasing means 20 for increasing the holding force of the main label ML suction-held on the outer peripheral surface is provided.

The holding force increasing means 20 sandwiches the lower portion of the main label ML between the lower portion of the main label ML and the outer peripheral surface of the transport drum 18 at the sub-label sticking position ω, and the sandwiching roller 21 of the transport roller 18. It is composed of a rotary drive mechanism 22 that rotates in the opposite direction to the conveying drum 18 at the same peripheral speed as the peripheral speed, and the sandwiching roller 21 has a sandwiching surface for sandwiching the main label ML made of a rubber material. . The sandwiching surface of the sandwiching roller 21 can be formed of a synthetic resin material or a metal material.

The rotary drive mechanism 22 is supported by bearings, and is rotatably supported by a rotary shaft 18a of the conveying drum 18 which is rotationally driven by a drive source and a power transmission mechanism (not shown). Spur gears 24 and 25 of the same diameter which mesh with each other and are attached to the relay shaft 23

The timing belt 29 is wound around these timing pulleys 27 and 28. The conveyance drum 18 and the nip roller 21 are mechanically synchronized and rotationally driven by the same drive source. It is supposed to be done.

Therefore, the main label ML conveyed from the first delivery position β to the second delivery position γ while being suction-held on the outer peripheral surface of the conveyance drum 18 is the sub-label attachment position ω.
When passing through, the nipping roller 21 cooperates with the carrying drum 18 to send the main label ML to the second delivery position γ side while sandwiching the main label ML between the main label ML and the outer peripheral surface of the carrying drum 18. The holding force of the main label ML with respect to the outer peripheral surface of the drum 18 is enhanced, and when the sub-labeler 40 attaches the sub-label SL to the main label ML, even if an impact or the like is applied to the main label ML, the main label ML is caused by the impact or the like. Therefore, the displacement of the main label ML in the circumferential direction or the vertical direction of the transport drum 18 can be reliably prevented. Particularly, as described above, when the sub label SL is attached to the upper part of the main label ML, the main label ML is
Is easily displaced, which is particularly effective in such a case.

As described above, this label sticking system 1
Then, since the sub-labeler 40 sticks the sub-label SL at a predetermined position of the main label ML while the main label ML is being conveyed by the conveying drum 18 in the main labeler 10, the main label ML is attached to the liquid product LG.
Just attach to the (bottle container B), once the main label is attached to the liquid product (bottle container), and then the sub-label is attached to the liquid product (bottle container) separately. Since it is not necessary to install a liquid product alignment device to which a main label is attached in the middle of a liquid product transfer line, it is possible to reduce equipment costs and minimize installation space. .

Further, at the stage of carrying the main label ML by the carrying drum 18, the main label ML basically passes through the sub-label sticking position ω with a constant period while keeping the main label ML in a predetermined carrying posture. The sub-label SL is provided only by performing intermittent feed control of the sub-label forming base material SM by the sub-labeler 40 in accordance with the passage timing of the main label ML passing through the sub-label attaching position ω while being suction-held on the outer peripheral surface of the transport drum 18. Main label M
It can be securely attached to a predetermined position of L.

In the above-described embodiment, the rotational driving force of the conveying drum 18 is transmitted to the nipping roller 21 via the rotational driving mechanism 22 so that the conveying drum 18 and the nipping roller 21 are mechanically synchronized. 21 and 21 are rotationally driven by a common drive source, but the present invention is not limited to this and, for example, FIGS. 7 (a) and 7 (b).
As shown in, it is also possible to drive the nip roller 21 by a servomotor 22A that is electrically synchronized with the rotational drive of the transport drum 18 and is independent of the drive source of the transport drum 18.

Further, in the above-described embodiment, in order to increase the holding force of the main label ML on the outer peripheral surface of the conveying drum 18, the nipping roller 21 for nipping the main label ML between the outer peripheral surface of the conveying drum 18 and Transport drum 18
Although it is made to rotate in the opposite direction to the conveying drum 18 in synchronism with the above, the nipping roller 21 for nipping the main label ML between itself and the outer peripheral surface of the conveying drum 18 does not necessarily have to rotate itself. Instead, at least, it may be rotatably supported.

Further, in the above-described embodiment, the main label ML is sandwiched between the outer peripheral surface of the conveying drum 18 by the nipping roller 21 to enhance the holding force of the main label ML with respect to the outer peripheral surface of the conveying drum 18. However, the present invention is not limited to this, and for example,
The main label ML is sandwiched between the outer peripheral surface of the transport drum 18 and the belt which is driven to rotate in synchronization with the transport drum 18, and the outer surface of the transport drum 18 is attached only when the main label ML passes near the sub-label sticking position ω. By increasing the suction force for sucking and holding the main label ML, the main label ML with respect to the outer peripheral surface of the transport drum 18 is increased.
It is also possible to enhance the holding power of.

In the above embodiment, the sub-label SL is attached to the main label ML, and then the predetermined information is printed on the surface of the main label ML.
It is also possible to print before attaching the sub label SL to the main label ML, and it goes without saying that a printing device need not be provided particularly when printing is not required.

Further, in the above-described embodiment, the label detection sensor for detecting the main label is provided to surely attach the sub label SL to the predetermined position of the main label ML, but the present invention is not limited to this. The main label M on the outer peripheral surface of the transport drum 18 without being displaced.
If L is suction-held, it is also possible to control the feeding timing of the sub-label forming substrate SM by the sub-labeler 40 according to the output signal from the encoder that detects the rotational position of the transport drum.

In the above embodiment, the sub label SL is attached to the main label ML while the main label ML is being conveyed by the conveying drum 18.
The present invention is not limited to this, and for example, as shown by the one-dot chain line in FIG. 1, the main label is provided on the front side of the feeding roller 11 for continuously feeding the main label forming base material MM to the cutting position α. Guide plate GP supporting the forming base material MM
And a sub-label S using a sub-labeler at a predetermined position of the main label forming base material MM in the installation portion of the guide plate GP, as indicated by an alternate long and short dash line arrow in FIG.
You may make it attach L sequentially.

As described above, when the sub label SL is attached to the main label forming base material MM and it is not necessary to print predetermined information such as the expiration date and the serial number on the main label ML, it is not always necessary. It is not necessary to provide the transport drum 18, and the main label ML may be delivered directly from the cutting transport means 12 to the attachment drum 14.

Further, in the above-described embodiment, the sticking portion c sticks the transparent sub-label SL to the main label ML, but the display of the main label is hidden by the stuck sub-label. If there is no problem or design problem, the sub-label sticking part is not always
It does not have to be transparent.

In the above-described embodiment, the sub label SL is attached to the surface of the main label ML so as to project upward from the upper edge of the main label ML, but the present invention is not limited to this. Without main label M
It is also possible to attach the sub-label SL so as not to project from the L.

Further, in the above-described embodiment, the heat-sensitive adhesive label is used as the main label ML, but the present invention is not limited to this, and a glue label can be used as the main label ML. is there. However, in that case, a gluing device must be installed around the sticking drum 14 between the second delivery position γ and the main label sticking position δ instead of the heating means such as the infrared heaters 15 and 16. It goes without saying that it will not happen.

In the above-described embodiment, the case where the main label ML and the sub-label SL are attached to the liquid product LG such as nutritional drink has been described, but the present invention is not limited to this and the label of the present invention is not limited thereto. It goes without saying that the sticking system can be applied when sticking two types of labels to various adherends.
