Further, the material of the label holding stand 24c is not particularly limited, but it is preferably made of a metal material or the like that has less friction with the label 300. Thereby, it is possible to effectively prevent the label 300 being transported from being distorted. Moreover, a rotating belt (not shown) can be used instead of the label holding stand 24c. The rotating belt rotates at the same speed as the first holding belt 24a and the second holding belt 24b. The label is stabilized because it is conveyed at the same conveyance speed by the rotating belt, the first holding belt 24a, and the second holding belt 24b. Alternatively, the rotating belt may be integrated with the first holding belt 24a or the second holding belt 24b to hold the label. The rotating belt is preferably made of the same material as the first holding belt 24a and the second holding belt 24b.

The article conveyance belt 51 is held by a drive roller that drives it and a driven roller that rotates as the drive roller rotates. The article conveyance belt 51 configured in this manner is driven to rotate by driving the drive roller. The drive roller is rotationally driven by a motor (not shown) or the like. The material of the article conveyance belt 51 is not particularly limited, and various materials can be used.

The article 200 placed on the article conveying belt 51 is suctioned and held on the article conveying belt 51 by being sucked by a vacuum device (not shown) or the like from a plurality of suction holes provided in the article conveying belt 51.

Here, the article conveyance belt 51 is arranged so as to be closest to the label attachment belt 41 at the most downstream position on the conveyance path of the label 300 by the label attachment belt 41. At the position where the article conveyance belt 51 approaches the label pasting belt 41 most, the label 300 conveyed by the label pasting belt 41 joins the article 200 conveyed by the article conveyance belt 51. Thereby, the label 300 is attached to the article 200 at a predetermined timing at the position.

FIG. 8 is a flowchart chronologically showing the operating state of the label pasting device according to the present embodiment. 9 to 14 and 16 to 20 are schematic plan views for explaining each point in the flowchart shown in FIG. 8, respectively. FIG. 15 is a front view of the feed belt and conveyor belt shown in FIG. 14. Next, with reference to FIGS. 8 to 20, the operation of the label pasting apparatus 1A according to the above-described embodiment will be described.

Note that, as described above, the label pasting apparatus 1A according to the present embodiment continuously manufactures a plurality of labeled articles 100 using the article 200 and the label 300 as materials.

First, as shown in FIGS. 8 and 9, at time T0, label setting and the driving of the conveyor belt 31 are started.

More specifically, first, the original label 301 is placed near the feeding mechanism 2A.
Further, a single continuous label body 302 forming the original label fabric 301 is hung on the driven roller 22 , and the leading end of the continuous label body 302 is set in the nip portion of the pair of label supply rollers 21 .

Here, in the label continuous body 302, at time T5, which will be described later, the first main surface 300(1), which is the main surface on the side defined by the adhesive layer 300b of the pair of main surfaces of the label 300, is energized. is placed so as to face the source 34.

Furthermore, in the activation mechanism 3A, the control unit 35 starts driving the drive roller 32, and the drive roller 32 rotates in the direction of arrow DR1 shown in FIG. Thereby, the conveyor belt 31 is driven to rotate at a predetermined speed. Note that the driving of the conveyor belt 31 continues until it is stopped at time T11, which will be described later.

After the setting of the original label 301 is completed, the control unit 35 starts driving the pair of label supply rollers 21 and the drive roller 25 in the feeding mechanism 2A. At this time, the pair of label supply rollers 21 rotate in the directions of arrows DR3a and DR3b shown in FIG. 9, respectively. As a result, the single label continuous body 302 is wound up by the label supply roller 21, and is supplied downstream from the cut blade 23 and the label support section 23a by the length of the label 300 of the label continuous body 302. be done. At this time, the drive roller 25 rotates in the direction of arrow DR4 shown in FIG. 9, thereby driving the feeding belt 24 to rotate. As a result, the leading end portion of the single continuous label body 302 is transferred from the label supply roller 21 to the feeding belt 24.

Note that the feeding belt 24 is controlled to accelerate from a standby state to the speed of the label feeding roller 21 when receiving the leading end portion of the continuous label body 302 from the label feeding roller 21 . Thereby, it is possible to effectively prevent distortion of the continuous label body 302 when the continuous label body 302 is transferred.

Next, as shown in FIGS. 8 and 10, the label 300 is cut out at time T1.

More specifically, the control unit 35 drives the cutting blade 23 in the direction of arrow AR1a shown in FIG. As a result, the portion of the continuous label body 302 supplied to the cutting blade 23 and the label support section 23a is separated into pieces, and as a result, the label 300 is cut out. Note that the label 300 is cut out while the label supply roller 21 and the feeding belt 24 are not driven. The cut out label 300 is placed on the feeding belt 24.

On the other hand, in the article conveyance mechanism 5A, conveyance of a plurality of articles 200 including article 200 is started. More specifically, the plurality of articles 200 placed on the article conveyance belt 51 are continuously conveyed in the direction of arrow AR10 shown in FIG.

Next, as shown in FIGS. 8 and 11, at time T2, the label 300 is conveyed by the feed belt 24.

More specifically, first, by driving the cutting blade 23 in the direction of arrow AR2a shown in FIG. 11, the cutting blade 23 is moved backward. Next, as the drive roller 25 rotates, the label 300 is conveyed on the conveyance path of the label 300 by the feeding belt 24. At this time, the label 300 is attracted to the feeding belt 24 by negative pressure from a blower, a vacuum device, or the like.

Next, as shown in FIGS. 8 and 12, at time T3, the label 300 is placed on standby on the feeding belt 24.

More specifically, the label detection sensor S1 provided on the above-described feeding belt 24 detects that the label 300 has been conveyed to a predetermined position, and outputs this detection information to the control unit 35. The control unit 35 that has obtained this information stops driving the drive roller 25, so that the label 300 waits at a predetermined position.

Next, as shown in FIGS. 8 and 13, the label 300 is transferred at time T4.

More specifically, first, the first article detection sensor S2 provided on the article conveying belt 51 of the article conveying mechanism 5A detects that the article 200 placed on and conveyed by the article conveying belt 51 is in a predetermined state. The conveyance to the position is detected, and this detection information is output to the control section 35. The control unit 35 that has obtained this information resumes driving the drive roller 25, and thereby the label 300 is fed out from the feeding belt 24 of the feeding mechanism 2A to the conveyance belt 31 of the activation mechanism 3A and transferred. It turns out.

Note that, when feeding the label 300 onto the conveyor belt 31, the feed belt 24 is controlled to accelerate from the standby state at time T3 to the speed of the conveyor belt 31. In this way, when the feeding belt 24 is provided separately from the conveyor belt 31, the belt length of the feeding belt 24 can be shortened compared to the case where the feeding belt is configured as one piece with the conveying belt. The feed belt 24 can be accelerated in a shorter time. Thereby, the continuous production of labeled articles 100 can be sped up.
Furthermore, compared to the case where the feeding belt is integrated with the conveyor belt, the drive rollers, motors, etc. used for accelerating the feeding belt 24 can be made smaller, so the device can be made more compact. Furthermore, by accelerating the feeding belt 24 to the speed of the conveyor belt 31 and then feeding out the label 300, it is possible to effectively prevent the label 300 from being distorted when the label 300 is transferred. can.

Next, as shown in FIGS. 8, 14, and 15, at time T5, the energy source 34 starts irradiating the energy 34a, and the adhesive layer 300b of the label 300 is activated.

More specifically, first, before the label 300 is transferred from the feeding mechanism 2A, the label 300 transferred to the conveyor belt 31 that has been continuously driven is a label caused by the conveyor belt 31. It is transported on 300 transport routes. At this time, the label 300 is attracted to the conveyor belt 31 by negative pressure from a blower, a vacuum device, or the like.

Next, in the activation mechanism 3A, the control unit 35 starts irradiation of the energy 34a by the energy source 34. Thereby, an irradiation area 31e is provided on the trajectory of the conveyor belt 31, which is an area to which the energy 34a is irradiated. Note that the irradiation of the energy 34a by the energy source 34 continues until it is stopped at time T6, which will be described later.

Next, the label 300 passes through an irradiation area 31e provided on the trajectory of the conveyor belt 31. As a result, the adhesive layer 300b of the label 300 is irradiated with the energy 34a. As a result, the adhesive layer 300b becomes activated.

Here, as described above, the conveyor belt 31 includes the first end holding belt 31a, the second end holding belt 31b, and the center holding belt 31c (see especially FIGS. 5 and 15). With this configuration, it is possible to effectively prevent the label 300 from warping when passing through the irradiation area 31e, but the details will be described later.

Next, as shown in FIGS. 8 and 16, at time T6, the control unit 35 stops the energy source 34 from irradiating the energy 34a.

Next, as shown in FIGS. 8 and 17, the label 300 is transferred at time T7.

More specifically, first, the control unit 35 starts driving the drive roller 42, and the drive roller 42 rotates in the direction of arrow DR5 shown in FIG. Thereby, the label pasting belt 41 is driven to rotate.

Next, the label 300 with the adhesive layer 300b activated in the irradiation area 31e is further transported toward the downstream side on the transport path of the label 300 by the transport belt 31.
Thereby, the label pasting belt 41 of the label pasting mechanism 4A receives the label 300 from the conveyor belt 31 of the activation mechanism 3A.

Note that when the label pasting belt 41 receives the label 300 from the conveyor belt 31, it is controlled to accelerate from the standby state at time T7 to the speed of the conveyor belt 31. In this way, when the label pasting belt 41 is provided separately from the conveyor belt 31, the belt length of the label pasting belt 41 is shorter than when the label pasting belt is configured as one body with the conveyor belt. Since the length can be shortened, the label pasting belt 41 can be accelerated in a shorter time. Thereby, the continuous production of labeled articles 100 can be sped up. Furthermore, compared to the case where the label pasting belt is integrated with the conveyor belt, the drive rollers, motors, etc. used to accelerate the label pasting belt 41 can be made smaller, so the device can be made more compact. . Furthermore, by accelerating the label pasting belt 41 to the speed of the conveyor belt 31 and then receiving the label 300, distortion of the label 300 during transfer of the label 300 can be effectively prevented. be able to.

Next, as shown in FIGS. 8 and 18, at time T8, the label 300 is placed on standby on the label pasting belt 41.

More specifically, when the label 300 is conveyed to a predetermined position on the conveyance path of the label 300 by the label pasting belt 41, the control unit 35 stops driving the drive roller 42. As a result, the label 300 is placed on standby at a predetermined position on the label pasting belt 41.

Next, as shown in FIGS. 8 and 19, at time T9, the label 300 is attached to the article 200.

More specifically, first, the second article detection sensor S3 provided on the article conveyance belt 51 of the article conveyance mechanism 5A detects that the article 200 has been conveyed to a predetermined position, and transmits this detection information to the control unit. Output to 35. The article 200 is placed on the article conveyance belt 51 and conveyed. The control unit 35, which has obtained the information that the second article detection sensor S3 has detected the article 200, resumes driving the drive roller 42.

The label 300 whose conveyance by the label pasting belt 41 has been resumed in this way merges with the article 200 conveyed by the article conveying belt 51 at the most downstream position on the conveyance path of the label 300 by the label pasting belt 41. . Then, the labeled article 100 is manufactured by supplying and pasting the label 300 to the article 200 at a predetermined timing at the position.

Here, when attaching the label 300 to the article 200, the label attaching belt 41 is controlled to accelerate from the standby state at time T8 to the conveying speed of the article conveying belt 51. Thereby, it is possible to effectively prevent distortion of the label 300 when the label 300 is attached.

Next, as shown in FIGS. 8 and 20, at time T10, the manufactured labeled article 100 is transported downstream.

Next, as shown in FIG. 8, at time T11, the drive of the conveyor belt 31 is stopped by the control unit 35.

By performing the operations from time T0 to T11 described above, the production of the labeled article 100 by the label pasting device 1A is completed.

If further labeled articles 100 are manufactured continuously, the operations at times T0 to T11 will be repeated. In this case, the setting of the original label 301 and the driving of the conveyor belt 31 at time T0 are performed only when manufacturing the first labeled article 100, and the operation at time T11 (i.e., the driving of the conveyor belt 31 is stopped). ) may be performed only when the production of the last labeled article 100 is completed.

That is, in the case where labeled articles 100 are continuously manufactured by continuously pasting a plurality of labels 300 onto a plurality of articles 200, cutting out the first label 300 (i.e., label pasting) The conveyor belt 31 is driven at a predetermined speed from the start of operation of the apparatus 1A to the time when the last labeled article 100 is carried out (that is, the end of operation of the label pasting apparatus 1A).

Here, by having the above-described configuration, in the label pasting device 1A according to the present embodiment, which is equipped with an activation mechanism that activates the adhesive layer of the label, the durability of the device is improved. There is.

Generally, when light energy such as ultraviolet rays or thermal energy such as hot air is irradiated or blown onto a belt that conveys labels, the heat generated on the belt by these energies and the irradiated light energy itself may cause damage. , the belt will deteriorate. In particular, when a specific portion of the belt is continuously irradiated with the energy 34a, the portion that is continuously irradiated with the energy 34a is heated to a very high temperature. In this case, the belt deteriorates particularly severely.

In this regard, in the label pasting device 1A according to the present embodiment, as described above, the control unit 35 starts from a time before the label 300 is transferred onto the conveyor belt 31 at the time T4. The driving of the conveyor belt 31 via the drive roller 32 is started, and this driving of the conveyor belt 31 is continued until the label 300 is transferred to the label pasting belt 41 at time T7.

That is, in the label pasting device 1A according to the present embodiment, when the label 300 passes through the irradiation area 31e, the control unit 35 causes the energy source 34 to irradiate the energy 34a to the irradiation area 31e. The control unit 35 also controls the conveyor belt 31 to move at a predetermined speed via the drive roller 32 after the label 300 is transferred to the feeding mechanism 2A until the label 300 is transferred to the label pasting mechanism 4A. Drive it with.

In this case, since the conveyor belt 31 is driven to rotate while the energy 34a is irradiated, the heat and light energy itself generated by the irradiation of the energy 34a is absorbed into the conveyor belt 31. It is suppressed from occurring only in a specific part of the body. This prevents a specific portion of the conveyor belt 31 from becoming high temperature and prevents a specific portion of the conveyor belt 31 from being continuously irradiated with light energy, and effectively prevents deterioration of the conveyor belt 31 due to the heat and light energy. Can be suppressed.

Furthermore, in the label pasting device 1A according to the present embodiment, the conveyor belt 31 continues to be driven even when the energy source 34 is not irradiating the energy 34a. In this case, it is possible to suppress the heat generated by the irradiation of the energy 34a from staying around the irradiation area 31e, thereby effectively suppressing the deterioration of the conveyor belt 31 due to the heat. can do.

Therefore, by configuring in this way, it is possible to improve the durability of the labeling device equipped with an activation mechanism that activates the adhesive layer of the label.

Further, as described above, the label pasting device 1A according to the present embodiment is configured so that the mechanical operation is performed by dividing into three mechanisms: the feeding mechanism 2A, the activation mechanism 3A, and the label pasting mechanism 4A. ing. Thereby, it becomes possible to operate the label pasting mechanism 4A continuously while operating the feeding mechanism 2A and the activation mechanism 3A intermittently. Further, by dividing the mechanism into the three mechanisms described above, it is also possible to independently set the transport speed of the label 300 in each mechanism.

In this case, when the label 300 passes through the irradiation area 31e, the conveyor belt 31 is driven so that the conveyance speed of the conveyor belt 31 is optimal for activating the adhesive layer 300b. can be controlled. This makes it possible to ensure the activation of the adhesive layer 300b, thereby improving the accuracy of attaching the label 300 to the article 200.

Furthermore, in the case of the above configuration, the driving of the label sticking belt 41 when the label 300 is stuck to the article 200 is performed so that the conveying speed of the label sticking belt 41 is equal to the conveying speed of the article conveying belt 51. It can be controlled to be the same. This makes it possible to attach the label 300 to the article 200 without causing wrinkles, folds, etc. in the label 300.

Furthermore, by being able to independently set the transport speed of the label 300 in the three mechanisms described above, it is possible to speed up the continuous production of labeled articles 100 by pasting the label 300 onto the article 200. Become.

Furthermore, in the label pasting device 1A according to the present embodiment, as described above, the conveyor belt 31 that holds the label 300 in the irradiation area 31e where the adhesive layer 300b is activated is includes a first end holding belt 31a, a second end holding belt 31b, and a center holding belt 31c.

With this configuration, both ends of the label 300 in the direction perpendicular to the conveying direction of the conveyor belt 31 are held by the first end holding belt 31a and the second end holding belt 31b. By activating the adhesive layer 300b, it is possible to effectively prevent the label 300 from warping. Thereby, the accuracy of attaching the label 300 to the article 200 by the label attaching device 1A can be improved. In particular, in the present embodiment, the above-mentioned effects can be significantly obtained because the label 300 is attracted to the conveyor belt 31 by a vacuum device or the like.

Note that in the label pasting device 1A according to the present embodiment described above, irradiation of the energy 34a by the energy source 34 is started at time T5 shown in FIG. 8, and the irradiation is stopped at time T6. The irradiation of the energy 34a by the energy source 34 may be controlled to be performed intermittently only while the label 300 is being transported by the transport belt 31 of the activation mechanism 3A.

In addition, in the label pasting device 1A according to the present embodiment described above, various processes are performed on the label 300 by three mechanisms: the feeding mechanism 2A, the activation mechanism 3A, and the label pasting mechanism 4A. , the label pasting device 1A does not necessarily have to include the feeding mechanism 2A and the label pasting mechanism 4A having the above-described configurations, and feeding the label 300 to the activation mechanism 3A and pasting the label 300 onto the article 200 is not necessarily necessary. , for example, may be done manually.

Furthermore, in the label pasting device 1A according to the present embodiment described above, the label holding stand 24c, the label holding stand 31d, and the label holding stand 24c, the label holding stand 31d, and the label Although the case where the holding stands 41c are provided adjacent to each other has been illustrated, instead of these label holding stands, an auxiliary belt driven to revolve may be provided at a position corresponding to the label holding stands. It is preferable that the auxiliary belt is made of the same material as the feed-out belt 24, etc. adjacent thereto, and is driven to revolve at the same speed. When configured in this way, the labels placed on the belt Since the difference between the frictional force between the label 300 and the feeding belt 24 and the like and the frictional force between the label 300 and the auxiliary belt can be reduced, distortion of the label 300 can be effectively prevented. Become.

Specifically, as shown in FIG. 21, the label 400 in the label pasting device 1B according to the present embodiment is formed by peeling a plurality of labels 400 from a single support sheet 402 on which a plurality of labels 400 are supported. This is a so-called tack label. A single support sheet 402 to which a plurality of labels 400 are attached forms a label material 401 by being rolled up into a roll.

As the support sheet 402, for example, a release film having a base film and a release layer provided on one of the pair of main surfaces of the base film is used.

The material of the base film constituting the support sheet 402 is not particularly limited, and for example, a synthetic resin film such as polyester resin, polystyrene resin, vinyl chloride resin, etc., or a plurality of laminated resin layers of different or the same type. Examples include laminated resin films, papers such as synthetic paper, plain paper, and high-quality paper, and laminated films in which two or more films selected from these are laminated. The thickness of the base film is not particularly limited, but is preferably, for example, 15 μm or more and 300 μm or less.

The release layer constituting the support sheet 402 is formed by applying a release agent containing, for example, a silicone resin to the surface of the base film. The thickness of the release layer is not particularly limited, but is preferably, for example, 0.1 μm or more and 3 μm or less.

The plurality of labels 400 are supported so as to be positioned at regular intervals in the longitudinal direction of the support sheet 402 on the side defined by the release layer of the pair of main surfaces of the support sheet 402.

Similarly to the label 300 according to the first embodiment described above, the label 400 is composed of a base material, an adhesive layer, and a design printing layer. The configurations such as the materials of the base material, adhesive layer, and design printing layer of the label 400 are the same as those of the base material 300a, adhesive layer 300b, and design printing layer 300c of the label 300, so the description thereof will not be repeated.

The feeding mechanism 2B of the label pasting device 1B according to the present embodiment includes a collection roller 121, four driven rollers 122 that rotate in accordance with the rotation of the collection roller 121, and a peeling section 123.

When the collection roller 121 is rotationally driven, it winds up the support sheet 402 forming the original label fabric 401 from the original label fabric 401 placed near the feeding mechanism 2B. As a result, the support sheet 402 from which the label 400 has been peeled off is accumulated on the collection roller 121. The collection roller 121 is rotationally driven by a motor or the like (not shown).

The peeling unit 123 is for peeling off the label 400 from the single support sheet 402 supplied from the original label 401 and to which the label 400 is attached. As shown in FIG. 21, the peeling section 123 is constituted by a wedge-shaped plate member in plan view, the tip of which is formed at a sharp angle.

In the label pasting device 1B according to the present embodiment configured as described above, as shown in FIG. When compared with that of the labeling device 1A, instead of time T1 (i.e., label cutting), time T2 (i.e., label transport), and time T3 (i.e., label waiting) shown in FIG. The difference is that the label is peeled off at T1B.

More specifically, as shown in FIGS. 22 and 23, at time T1B, the collection roller 121 rotates in the direction of arrow DR6 shown in FIG. As a result, the support sheet 402 to which the label 400 is attached is conveyed along the conveyance path provided by the collection roller 121 and the four driven rollers 122.

Next, the support sheet 402 to which the label 400 is attached is sharply bent at the tip of the peeling part 123 along the shape of the peeling part 123. As a result, the label 400 is peeled off from the support sheet 402, and at the next time point T4, the peeled label 400 is transferred from the feeding mechanism 2B to the conveyor belt 31 of the activation mechanism 3A. Become.

Even with this configuration, the same effects as those described in the first embodiment described above can be obtained.
