Description

  The present invention relates to a label attaching apparatus that automatically attaches a label to a body of an article having a columnar or cylindrical body.

Conventionally, as this kind of label sticking device, for example, one disclosed in Japanese Patent Laid-Open No. 52-92100 (Patent Document 1) is known.
As shown in FIG. 9, a label L is attached to the outer peripheral surface of the body portion D of the article W in a bin as an article W having a body portion having a circular cross section whose outer periphery is centered on the axis. The articles W are conveyed in contact with the holding roller 201 at the outer periphery of the disk 200 so that the axis thereof is vertical, and are sequentially aligned at a predetermined interval, and the magazine 202 is rotated by the drum 202 during the conveyance process. The label L is adsorbed from 203, and the label L is glued by the gluing device 204. The glued label L is brought into contact with the outer peripheral surface of the article W, and at the time of contact, as shown in FIG. 9B. The label L is affixed to the outer peripheral surface of the body portion D of the article W by holding the article W from above and below and rotating it around the axis line by a rotation mechanism (not shown). Then, the article W to which the label L is attached comes into contact with the brush row 205 on the downstream side of the transport of the disk 200, so that the label L is reliably attached.

JP 52-92100 A

  However, in the above-described conventional label sticking apparatus, the article W is held and rotated from above and below in the axial direction as shown in FIG. Since the relationship between 202 and the holding roller 201 is unambiguous, it is good if the error of the outer diameter of the article W is relatively small like a bottle, but if the error of the outer diameter is large, the label L is sufficiently applied. In addition, when a label is affixed to an article having a different outer diameter, the rotating mechanism and the drum 202 cannot be handled. Therefore, when a label is affixed to an article having a different outer diameter, it is necessary to change the setting of the rotating mechanism and the drum. In other words, the conventional apparatus is suitable for handling a large amount of articles with good outer diameter accuracy, but is not suitable for multi-product small-quantity production.

The present invention has been made in view of the above problems, and even when the error of the outer diameter of the article is large or in the case of a lot with different types of outer diameters, the article is reliably rotated to label it. An object of the present invention is to provide a label sticking device that can be reliably stuck, and is therefore suitable for a small variety of small-quantity production.

  In order to solve the above-mentioned problem, the label sticking device of the present invention is the label sticking device for sticking a label to the outer peripheral surface of the trunk portion of the article having a circular cross section whose outer periphery is centered on the axis. A rolling holding portion that holds the body portion of the article while rotating the rolling holding portion about a rotation axis so that the axis of the article is parallel to the rotation axis. And a pair of guide rollers having a rotating shaft parallel to the support roller and guiding both sides of the body portion of the article supported by the support roller. And a rotational drive unit that rotationally drives the support roller, and adsorbs the label and elastically presses the adsorbed label against the body of the article that is rolled by the rolling holding unit. Along the circumferential direction of the barrel It has a configuration provided with a label suction press section it is labeled Te.

Thereby, when sticking a label, an article | item is first hold | maintained at a rolling holding | maintenance part. In this case, the body is supported on the support roller so that the axis of the article is parallel to the rotation axis of the support roller. In this state, both sides of the body portion of the article are guided by the pair of guide rollers. And a support roller is rotated by the rotation drive part of a rolling holding part, and articles | goods are rolled.
The label adsorbing and pressing unit elastically presses the label adsorbed on the body of the article that adsorbs the label and rolls on the support roller of the rolling holding unit. Thereby, since the label is pressed against the article by the pressing roller, the label is pulled from the adsorbent by the rotation of the article, and is wound around and stuck to the article.

In this case, since the article is supported by the support roller and is elastically pressed, even if the error of the outer diameter of the article is large, this error is absorbed, and the article is forced on the support roller. So that the label is securely attached.
For this reason, even if the error of the outer diameter of the article is large, or even in the case of a lot with a slightly different type of outer diameter, the label can be attached by rolling the article without difficulty. It can be adapted very well and the versatility can be improved.

  Then, if necessary, the pair of guide rollers of the rolling holding portion can be opened and closed, and the pair of guide rollers is attached to the body portion of the article supported by the support roller by urging the guide roller in the closing direction. A structure provided with an urging means for elastic contact, and an opening drive part for opening the guide roller against the urging force of the urging means and making the width between the guide rollers wider than the width of the body part of the article. It is said.

  Thus, when the article is held in the rolling holding portion, the guide roller is opened against the urging force of the urging means by the opening drive portion. In this case, since the width between the guide rollers is wider than the width of the body portion of the article, the article can be easily inserted from between the guide rollers and can be easily supported by the support roller. Further, after the article is supported, when the opening drive of the opening drive unit is released, the guide roller is closed by the urging force of the urging means to contact the article and guide it. Therefore, even if the error of the outer diameter of the article is large, or even in the case of lots with slightly different types of outer diameter, the article can be guided without difficulty and can be adapted very well in the case of high-mix low-volume production. , Versatility can be improved.

  In addition, if necessary, a plurality of support rollers having different outer diameters are connected in series, and corresponding to the plurality of support rollers having different outer diameters, a pair of guide rollers of the above-mentioned rolling holding portion, which are different sets. A plurality of pairs of guide rollers each having a different outer diameter between the guide rollers are arranged side by side. When the article is of a type in which a plurality of body parts having different outer diameters are provided in series, each body part is supported by a support roller and can be guided by a guide roller, so that the holding can be ensured.

  Further, if necessary, an axial positioning mechanism for positioning the positions of both ends in the axial direction of the article supported by the support roller of the rolling holding part before the label is stuck to the article by the label suction pressing part. It has a configuration with. Since the movement of the article in the axial direction can be restricted, the holding is ensured.

  In this case, the axial positioning mechanism is moved forward and backward with respect to the fixed stopper with which one end portion of the article supported by the support roller of the rolling holding portion abuts and the other end portion of the article supported by the support roller. It is effective to include a movable stopper that is provided so as to abut against the other end portion of the article when advancing and press the article toward the fixed stopper. The movable stopper is retracted to support the article on the support roller, and then the movable stopper is advanced to restrain the article, so that the article can be easily inserted and easily supported on the support roller.

  Further, in this case, the fixed stopper is provided with a rotation shaft in a direction perpendicular to the axis of the article supported by the support roller, and is provided so as to contact one end portion of the article with a predetermined distance from each other. The movable stopper has a rotation shaft in a direction perpendicular to the axis of the article supported by the support roller, and is abutted against the other end of the article with a predetermined distance from each other. It is effective to include a pair of contact rollers provided so as to be in contact with each other. Since the fixed stopper and the movable stopper are configured to include the contact roller, a situation that hinders the rotation of the article around the axis is prevented.

  Further, if necessary, before the label is affixed to the article by the label suction pressing unit, the label is properly affixed to a predetermined affixing site to which the label of the article is affixed. It is configured to include rolling positioning means for positioning the article application site at a predetermined rolling position with respect to the support roller. As a result, the label can be properly affixed to a predetermined affixing site where the label of the article is affixed.

  In this case, when the rolling positioning means is rotated by the rotation driving unit, the detection site having a predetermined relationship with the application site of the article supported by the support roller during rotation of the support roller is the support roller. A detection sensor for detecting whether or not the rotation drive unit is positioned, and starting the rotation drive unit and detecting that the detection sensor is positioned at the predetermined rotation position. It is effective to include a control unit for stopping.

  Further, if necessary, the label suction pressing portion is provided at a position where the label adsorbs the front end of the label to adsorb and the upper side of the front end of the label protruded from the adsorbent and holds the rolling. A pressure roller that has a rotation axis parallel to the rotation axis of the support roller of the part and presses the label against the body of the article supported by the support roller from the upper side of the support roller; The holding roller is arranged and held in parallel in a direction orthogonal to the rotation axis of the support roller, and is moved forward and backward to two positions: an adsorption position where the adsorber adsorbs the label and a pressing position where the pressing roller presses the label against the body portion of the article. A movable holding body and an advancing / retreating drive unit that moves the holding body back and forth to the suction position and the pressing position are configured. Since the body portion of the article is pressed against the support roller by the pressing roller, the rotation of the support roller is reliably transmitted to the article, the article is reliably rolled, and the label is securely attached. There is also an effect that an existing apparatus can be used.

In this case, if necessary, the holding body is configured to include a base and a mounting member provided on the base so as to be tiltable and to which the adsorbing body and the pressing roller are attached, and the mounting member is used as a base at the pressing position. It is set as the structure provided with the tilting drive part which inclines with respect to it and makes only the said press roller contact | abut to the trunk | drum of the said article | item. Since only the pressing roller is brought into contact with the body portion of the article, the rotation of the support roller is reliably transmitted by the article.

According to the label sticking device of the present invention, when sticking a label, the label sucking and pressing portion elastically presses the label onto the trunk of the article rolling on the support roller of the rolling holding portion. Therefore, since the article is supported by the support roller and is elastically pressed, even if the error of the outer diameter of the article is large, this error is absorbed, and the article moves on the support roller. Since it can roll without difficulty, the label can be reliably attached. Also, even if the error of the outer diameter of the article is large, or even in the case of lots with slightly different types of outer diameters, the label can be attached by rolling the article without difficulty. It can be well adapted and versatility can be improved.

Therefore, when the label L is stuck on the articles WA and WBW by the label sticking apparatus according to the embodiment of the present invention, it is as follows.
First, the case where the label L is stuck on the article WA shown in FIG.
As shown in FIG. 1 and FIG. 4A, each set of the guide rollers 17 is set to be opened by the opening drive unit 21 at the receiving / extracting position Ja of the base body 11. That is, the piston 23 of the air cylinder device 22 of the opening drive unit 21 advances and presses the projection 24 of the arm 19, and the arm 19 is opened in the opening direction against the urging force of the coil spring as the urging means 20. The guide roller 17 is opened by swinging. Further, the movable stopper 33 of the axial positioning mechanism 30 is retracted.

  In this state, the article WA is supported on the support roller 12 by manual operation or automatically by a supply device (not shown) so that the axis P of the article WA is parallel to the rotation shaft 15 of the support roller 12. At this time, as shown in FIG. 4, the body portion DA of the article WA is supported on one pair of support rollers 12 (A) and 12 (A). In this case, the width between the guide rollers 17 is wider than the width of the body portion DA of the article WA, and the movable stopper 33 is retracted, so that the article WA is easily inserted from between the guide rollers 17 and the support rollers. 12 is supported.

  Next, as shown in FIG. 1 and FIG. 4B, the base 11 is moved from the receiving / extracting position Ja to the attaching position Jb. The piston 23 of the air cylinder device 22 of the opening drive unit 21 moves backward in the process of moving to the receiving / extracting position Ja and the attaching position Jb, or in the attaching position Jb. As a result, the arm 19 is swung in the closing direction by the urging force of the coil spring as the urging means 20, and the guide roller 17 contacts and guides the article WA. At this time, the guide rollers 17 (A) and 17 (A) of the set of one guide roller 17 guide both sides of the body DA of the article WA.

  Further, as shown in FIG. 4B, the air cylinder device 35 of the axial positioning mechanism 30 is driven, the movable stopper 33 advances, contacts the other end of the article WA, and the article WA is fixed to the fixed stopper. Press to 31 side. Thereby, the article WA is held between the fixed stopper 31 and the movable stopper 33. Therefore, since the movement of the article WA in the axial direction can be restricted, the holding is ensured. Since the fixed stopper 31 and the movable stopper 33 are configured to include the contact rollers 32 and 34, there is no hindrance to the rotation around the axis P of the article WA.

In this state, as shown in FIG. 5, the rolling positioning means 40 is operated, and the article L is properly attached to a predetermined application site E to which the label L of the article WA is attached. The sticking part E of the WA is positioned at a predetermined rolling position with respect to the support roller 12.
Specifically, first, as shown in FIGS. 5A and 5B, the holding body 54 of the label suction pressing unit 50 advances to the pressing position Y and presses the pressing roller 53 against the article WA. In this case, first, the air cylinder device 55 advances to lower the holding body 54, and then, as shown in FIG. 5C, the air cylinder device 60 advances to attach the attachment member 58 to the base 57. Tilt to press the pressing roller 53 against the article WA.

Next, as shown in FIG. 5 (c), the electric motor 16a of the rotation drive unit 16 is started, the support roller 12 is rotated, and the article WA is rolled. In this case, since the pressing roller 53 of the label suction pressing unit 50 is pressed by the article WA, the article WA is reliably rolled. Further, since the article WA is guided by the guide roller 17, the article WA is surely rolled also in this respect. In this rolling process, the detection sensor 41 (FIG. 2) detects the specific terminal T (a) (detection part) of the article WA, and when the detection sensor 41 detects the specific terminal T (a), the rotation drive is performed. The electric motor 16a of the portion 16 is stopped, and thereby the application site E of the article WA supported by the support roller 12 is positioned at a predetermined rolling position with respect to the support roller 12.
Thereafter, as shown in FIG. 5D, the holding body 54 of the label suction pressing unit 50 moves back to the suction position X. In this case, the air cylinder device 60 moves backward to return the mounting member 58 to the original position with respect to the base 57, and the air cylinder device 55 moves backward to raise the holding body 54, so that the holding body 54 is moved to the suction position X. Position.

As shown in FIG.
Next, this apparatus performs label L sticking operation. First, as shown in FIGS. 2 and 6A, the label L is supplied from the label supply unit 1 by the paper detection sensor 6, and the label L is adsorbed to the adsorbent 51. At this time, the front end of the label L protruded from the adsorbent 51 comes into contact with the upper pressing roller 53. Further, as shown in FIG. 3, the label L peeled off by the peeling plate 3 of the label supply unit 1 protrudes from the belt-like mount D by the length in the short direction Rb. It will be maintained and will be adsorbed to the adsorbent 51 while maintaining a flat body. Therefore, it will be prevented from drooping due to the moment load of its own weight, and a trapping error in the adsorbent 51 will be prevented, and it will be adsorbed reliably. It can be adsorbed on the body 51.

Then, as shown in FIGS. 1, 2, and 6 (b) and 6 (c), the holding body 54 of the label suction pressing portion 50 advances to the pressing position Y, and the front end of the label L is attached to the article via the pressing roller 53. Press against WA. In this case, first, as shown in FIG. 6B, the air cylinder device 55 advances to lower the holding body 54, and then, as shown in FIG. 6C, the air cylinder device 60 advances. Then, the mounting member 58 is tilted with respect to the base 57 to press the pressing roller 53 against the body DA of the article WA.
At this time, since the application part E of the article WA supported by the support roller 12 is positioned at a predetermined rolling position with respect to the support roller 12, a predetermined application part to which the label L of the article WA is attached is provided. A front end of the label L is properly attached to E.

In this state, as shown in FIG. 6C, the electric motor 16a of the rotation driving unit 16 is started, the support roller 12 is rotated, and the article WA is rolled. At this time, since the pressing roller 53 of the label suction pressing unit 50 is pressed by the body DA of the article WA, the article WA is reliably rolled. Further, since the article WA is guided by the guide roller 17, the article WA is surely rolled also in this respect. In this rolling process, since the label L is pressed against the body DA of the article WA by the pressing roller 53, the label L is pulled from the adsorbent body 51 by the rotation of the article WA, and is wound around the body DA of the article WA. Affixed.
In this case, the article WA is supported by the support roller 12, and the pressure roller 53 rolls on the support roller 12 of the rolling holding unit 10 by the elastic force of the air of the air cylinder device 60. Can be reliably elastically pressed. Therefore, even when the error of the outer diameter of the article WA is large, the pressing roller 53 moves up and down following this error, so that the article WA can roll on the support roller 12 without difficulty. The label L is affixed reliably.

  In this case, the article WA is guided by the guide roller 17, but the guide roller 17 is in contact with the article WA by the urging force of the coil spring as the urging means 20, so that the outer diameter of the article WA is reduced. Even when the error is large, the guide roller 17 moves back and forth following this error, so that the article WA can roll on the support roller 12 without difficulty. It will be affixed to.

When the application of the label L is finished, the holding body 54 of the label suction pressing unit 50 moves backward to the suction position X as shown in FIG. In this case, the air cylinder device 60 moves backward to return the mounting member 58 to the original position with respect to the base 57, and the air cylinder device 55 moves backward to raise the holding body 54, so that the holding body 54 is moved to the suction position X. Position.
And as shown in FIG. 1, the base | substrate 11 is moved to the picking-out position Ja from the sticking position Jb. Each set of guide rollers 17 is set to open by the opening drive unit 21. That is, the piston 23 of the air cylinder device 22 of the opening drive unit 21 advances to press the projection 24 of the arm 19 and swings the arm 19 in the opening direction against the urging force of the coil spring as the urging means 20. The guide roller 17 is opened. In this state, the article WA is automatically taken out manually or by a take-out device (not shown).

  In this way, the labels L are sequentially attached to the article WA. In this case, the article WA is supported on the support roller 12 and the label L is pressed against the body DA of the article WA. Therefore, when the error of the outer diameter of the article WA is large, or the lots of slightly different types of outer diameters are used. Even in this case, it is possible to roll the article WA without difficulty and to apply the label L. Therefore, it can be very well adapted to the case of high-mix low-volume production, and the versatility can be improved.

  Next, the case where the label L is stuck on the article WB shown in FIG. In the case of this article WB, the pasting operation is performed in substantially the same manner as described above. In this case, as shown in FIG. 7, one pair of support rollers 12 (A), 12 (A) supports the small-diameter body DB of the article WB, and the other support roller 12 (B) The large diameter body DC of the article WB is supported. Further, the guide rollers 17 (A) and 17 (A) of the set of one guide roller 17 guide both sides of the small-diameter body DB of the article WB, and the guide rollers 17 (B of the other guide roller 17 set). ), 17 (B) guides both sides of the large-diameter body DC of the article WB.

  Also in this case, since the article WB is supported by the support roller 12 and is pressed by the pressing roller 53, even if the error in the outer diameter of the article WB is large, the pressing roller 53 follows the error and moves up and down. Since the article WB moves, the article WB can roll on the support roller 12 without difficulty, so that the label L is reliably attached to the small-diameter body DB of the article WB. The article WB is guided by the guide roller 17, but the guide roller 17 is in contact with the article WB by the urging force of the coil spring as the urging means 20, so that an error in the outer diameter of the article WB is large. Even in such a case, since the guide roller 17 moves back and forth following this error, the article WB can roll on the support roller 12 without difficulty, so that the label L is reliably adhered also in this respect. To go.

  In addition, the article WB has a small-diameter body DB and a large-diameter body DC, and each of the body DB, DC has a support roller 12 (A), corresponding to these outer diameters. 12 (B) and guided by the guide rollers 17 (A) and (B) corresponding to these outer diameters, compared to the case of simply being held by a kind of the supporting roller 12 and the guide roller 17, The holding is ensured, and therefore, the label L can be reliably attached also in this respect.

In addition, the support roller 12 and the guide roller 17 are not limited to the structure which arranges large and small in parallel as mentioned above, The thing of one type of outer diameter may be sufficient. Moreover, according to the difference in the outer diameter of the trunk | drum of an article | item, you may make it provide the thing of three or more types of outer diameters connected, and can change suitably.
Further, in the type in which a plurality of body portions DB, DC having different outer diameters are connected like the article WB, the support roller 12 and the guide roller 17 may be configured with one type of outer diameter. Although it is good, it is preferable to provide the support roller 12 and the guide roller 17 having a plurality of types of outer diameters corresponding to the outer diameters of the body portions DB and DC, because the holding is ensured.
Moreover, in the said embodiment, the shape of the article handled is not limited to said 2 types, Of course, what kind of thing may be sufficient if an outer periphery has a circular trunk | drum.
