Description

  The present invention relates to a label sticking apparatus and a label sticking method for sticking a plurality of labels to an outer peripheral surface of a sticking object.

  Conventionally, a plurality of labels are sucked and held on the outer peripheral surface with the sticking surface facing outward, and a plurality of labels sucked and held on the outer peripheral surface while rotating are brought into contact with the adherend. A plurality of labels that are attached to the sticking body and a plurality of labels are supplied to the sticking drum at a predetermined timing, and a plurality of labels are sucked and held on the outer peripheral surface of the sticking drum at predetermined intervals. There is known a labeling device that includes a plurality of label supply means, and each of the plurality of label supply means is driven by a servo motor provided individually (see, for example, Patent Document 1).

  Further, as in Patent Document 2, the sheet conveying unit is configured to feed a plurality of adhesive sheets fed out from a single feeding unit in parallel to the feeding direction of the adhesive sheet and the support surface of the sheet conveying unit and orthogonal to the feeding direction of the adhesive sheet. A plurality of adhesive sheets are provided so as to be able to contact a single adherend, and the pressing means includes a pressing member that presses the adherend, and a sheet conveying means. Press the adhesive sheet against the adherend while moving the pressing member in the same direction and at the same speed or less, or moving it in the opposite direction and at the same speed or less with respect to the conveyance direction and conveyance speed of the adhesive sheet.

Japanese Patent Laid-Open No. 11-321831 JP 2011-93582 A

  However, in the labeling apparatus of Patent Document 1, a pair of star wheels must be provided in the bottle conveying means for conveying the bottle according to the outer diameter of the bottle, and the bottle shape corresponds to a sticking object such as a square cross section. There is a problem that it is difficult.

  On the other hand, in the label sticking apparatus of Patent Document 2, since the adhesive sheet is fed out from a single feeding means, it looks compact at first glance, but has only one adhesive sheet attached to one support roller. It is extremely difficult to affix a plurality of different paper-quality labels on this single adhesive sheet in terms of the label manufacturing method. For example, as a label for wine bottles, a good quality paper label with a product name, mark, etc. is affixed on the front side, and a label that displays materials etc. with a cheaper paper quality than the front side is affixed to the back side There are many. Also, in order to print the date or the like, only the back side may be used as a thermal paper label. Since the thing of patent document 2 has only one adhesive sheet, there exists a problem that it cannot apply to what affixes different labels, such as such paper quality. In addition, there is no space for increasing the number of adhesive sheets to 3 or more and providing a printer for printing the date and the like. In addition, if an object to be pasted that is not circular in cross section, such as a rectangular cross section, is passed, there is a risk that the label will not be applied neatly because it does not rotate smoothly.

  This invention is made | formed in view of this point, The place made into the objective is to stick easily and reliably on the outer peripheral surface of a sticking target object even if it is several labels from which paper quality differs.

  In order to achieve the above object, in the present invention, a plurality of labels adsorbed by the adsorbing belt are affixed to the outer peripheral surface of the object to be adhered that is pressed and rotated by the rotation auxiliary portion.

Specifically, in the first invention, on the premise of a label sticking device for sticking a plurality of labels to the outer peripheral surface of the sticking object,
The labeling device is
A transport device that drives the transport belt on which the pasting object is placed at a first speed;
A plurality of label delivery devices for delivering the plurality of labels from separate label rolls;
A label adsorbing device that has an adsorbing belt on which the plurality of labels sent out of the plurality of label sending devices are temporarily adsorbed, and that drives the adsorbing belt at a second speed;
The sticking object that is provided at a position facing the suction belt and that has been transported by the transport belt is pressed against the suction belt side, and is made of a material softer than the sticking object. And a rotation assisting portion that can be deformed according to the shape of the outer peripheral surface.

  According to the above configuration, the labels are delivered from the separate label rolls of the plurality of label delivery devices at appropriate intervals and are attracted to the suction belt. The conveyance object conveyed by the conveyance belt is smoothly rotated on the conveyance belt while being pressed by the rotation auxiliary portion, and a plurality of labels are attached to the outer periphery thereof. At this time, even if the object to be applied has a cross-sectional shape other than a circular shape such as a rectangular cross-section, the rotation assisting part presses the object to be adhering to the suction belt side while being appropriately deformed, so that the label is securely attached. Attached. In addition, since a plurality of labels are attached at the same time, it is not necessary to reliably control the attaching positions of the second and subsequent labels as in the case of attaching each label at a different position. Furthermore, since it has a plurality of label delivery devices, it is possible to use a label roll to which labels of different materials are attached. For this reason, for example, as a label for a wine bottle or the like, a label with good paper quality with a product name, a mark, etc. is pasted on the front side, and on the back side, a material or the like is displayed with cheaper paper quality than the front side. Can be pasted.

In the second invention, in the first invention,
The sticking object has a circular cross section, and is configured so that no slip occurs between the sticking object and the rotation assisting part.
The second speed is twice the first speed.

  According to the above configuration, when the object to be applied has a circular cross section, and when no slip occurs between the rotation holding unit and the object to be applied, the object to be applied is conveyed before and after the label is applied. The speed does not change, and the sticking object can be transported without delay.

In the third invention, in the first or second invention,
The rotation auxiliary part is a sponge-like member.

  According to said structure, it can be made to rotate smoothly by pushing back with a suitable reaction force with a simple and cheap material, without damaging a sticking target object.

In the fourth invention, in any one of the first to third inventions,
A printing machine for writing information on a label fed out from the label delivery device is provided on the downstream side of one of the plurality of label delivery devices and on the upstream side of the suction belt.

  According to said structure, the character etc. which change suitably, such as a date, can be printed on a label with a printing machine. Moreover, since the label sending device is composed of a plurality of label sending devices, it is easy to provide a printing machine between them.

In 5th invention, on the premise of the label sticking method of sticking a plurality of labels on the outer peripheral surface of the sticking object,
The labeling method is
While transporting the pasting object placed on the transport belt at a first speed,
The plurality of labels are sent out from the label rolls of the plurality of label delivery devices, respectively, and attached to the suction belt driven at the second speed while being shifted in position,
A sticking object that rotates on the conveying belt while pressing the sticking object conveyed by the conveying belt to the suction belt side by a rotation auxiliary portion provided at a position facing the sucking belt. The rotation assisting portion is supported while being deformed in accordance with the shape of the outer peripheral surface of the adhesive, and the plurality of labels are respectively attached to positions shifted from the outer peripheral surface of the pasting object.

  According to the above configuration, the labels are separately sent from the plurality of label sending devices at appropriate intervals and sucked to the suction belt. The conveyance object conveyed by the conveyance belt is smoothly rotated on the conveyance belt while being pressed by the rotation auxiliary portion, and a plurality of labels are attached to the outer periphery thereof. At this time, even if the object to be applied has a cross-sectional shape other than a circular shape such as a rectangular cross-section, the rotation assisting part presses the object to be adhering to the suction belt side while being appropriately deformed, so that the label is securely attached. Attached. In addition, since a plurality of labels are attached at the same time, it is not necessary to reliably control the attaching positions of the second and subsequent labels as in the case of attaching each label at a different position. Furthermore, since it has a plurality of label delivery devices, it is possible to use a label roll to which labels of different materials are attached.

  As described above, according to the present invention, even a plurality of labels having different paper qualities can be easily and reliably attached to the outer peripheral surface of a sticking object while smoothly rotating.

It is a top view which shows the label sticking apparatus which concerns on embodiment of this invention. It is a front view which shows the label sticking apparatus which concerns on embodiment of this invention. It is an enlarged plan view which shows the outline of a mode that a label is affixed while rotating a bin.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG.1 and FIG.2 shows the label sticking apparatus 1 of embodiment of this invention, and this label sticking apparatus 1 has a function which sticks the some label L to the outer peripheral surface of the bin W as a sticking target object. In FIG. 1, the pasting target is a bin W having a circular cross section, but the cross section is not particularly limited, such as an ellipse, a rectangle, or a triangle. And cans and boxes other than bottles are not particularly limited.

  And this label sticking apparatus 1 is provided with the base 2 which consists of steel frames etc., and this base 2 is provided with the leg part 3 and the wheel 4 in the lower end part, for example. On the upstream side of the base 2, a transport device 10 that drives the transport belt 11 on which the bin W is placed at the first speed V <b> 1 is provided. The conveyance belt 11 is made of, for example, a plastic belt, and the adhesion target object is easily rotated on the object while the conveyance object such as the bin W placed thereon is reliably conveyed. The transport device 10 includes a transport motor 12, and the transport belt 11 is driven at the first speed V1 by the transport motor 12. Conveying guides 13 are erected on both sides in the width direction of the conveying belt 11 so as to guide the bin W to the downstream side without falling from the conveying belt 11. A separation device 14 is provided on one side of the conveyance guide 13. A separation sensor 15 is provided on the upstream side of the separation device 14. The separation sensor 15 detects the bin W, and the separation device 14 leaves the appropriate pitch P 1 to flow the bin W downstream. ing.

  The label sticking device 1 includes a first label sending device 20 and a second label sending device 21 that send a plurality of labels L from separate label rolls 23. Although not shown in detail, the label roll 23 is made of, for example, a label base paper composed of three elements of a surface base material, an adhesive material, and a release paper, which is wound by printing or cutting. As the surface base material, various paper materials are used according to the application, and in many cases, different paper materials are used on the front side and the back side of the bin W. In the present embodiment, two label sending devices 20 and 21 are provided, but three or more may be provided depending on circumstances. In the first label delivery device 20 and the second label delivery device 21, a label roll 23 in which a number of different labels L are arranged is rotatably mounted on the supply rollers 20a and 20b. The label base paper supplied from the supply rollers 20a and 20b is peeled off from the release paper at the leading ends of the first label delivery device 20 and the second label delivery device 21, respectively, and then the release paper is collected into the recovery rollers 21b and 22b. It comes to be collected at. The first label delivery device 20 and the second label delivery device 21 can be controlled by a first labeler control panel 24 and a second labeler control panel 25, respectively. The first labeler control panel 24 and the second labeler control panel 25 are each provided with a labeler up / down handle 26, a labeler front / rear handle 27, a labeler direction adjustment handle 28, etc., so that the label L attaching position can be adjusted appropriately. Yes. A label sending sensor 16 is provided on the upstream side of the leading end portion that sends out the label L. For ease of viewing, the first label sending device 20 and the second label sending device 21 are omitted in FIG. 2 except for the first labeler control panel 24 and the second labeler control panel 25.

  A plurality of label L destinations sent from the first label sending device 20 and the second label sending device 21 are sent from the first label sending device 20 and the second label sending device 21 with their positions shifted from each other. Here, there is provided a suction belt 31 on which two labels L are temporarily sucked, and a label suction device 30 for driving the suction belt 31 is provided. As for the two labels L, the surface opposite to the adhesive material is adsorbed by the adsorbing belt 31. This suction force is assumed to be smaller than the adhesive force of the label L. Although not shown in detail, the suction belt 31 has a number of suction holes, and the suction fan 33 provided in the sealed suction device casing 32 sucks air from the suction holes by the action of the suction fan 33. The label L is sucked to the belt 31 with an appropriate force. The suction belt 31 is driven by the suction motor 34 at the second speed V2. As will be described later, when the second speed V2 of the suction belt 31 is twice the first speed V1 of the transport belt 11 (V2 = 2V1), the pitch P2 after the label L is pasted is the pitch P1 before the label L is pasted. Is almost equal to Here, “substantially equal” means that it may not be completely equal, and may be slightly different. Note that the second speed V2 does not have to be twice the first speed V1 of the conveyor belt 11 when the bin W has a circular cross section or when a pitch deviation is allowed.

  A printing machine 29 is provided on the downstream side of the first label delivery device 20 and upstream of the suction belt 31 to appropriately write information such as date on the label L fed from the first label delivery device 20. For example, when the surface base material of the label L of the label roll 23 on the first label delivery device 20 side is made of thermal paper, the printing machine 29 may be a thermal printer.

  A rotation assisting unit 40 is provided at a position facing the suction belt 31 to press the bin W transported by the transport belt 11 against the suction belt 31 side. The rotation assisting part 40 is made of a material softer than the object to be pasted such as the bottle W, such as a sponge, on the side facing the suction belt 31. The rotation auxiliary unit 40 is provided in a sponge pressing mechanism 41 that presses the rotation auxiliary unit 40 toward the suction belt 31 side. The position of the rotation auxiliary unit 40 in the width direction of the conveying belt 11 can be adjusted by a rotation auxiliary positioning handle 42. As described above, the rotation assisting portion 40 is configured to be deformable according to the shape of the outer peripheral surface of the bin W, so that even if the cross-sectional shape of the pasting target is a triangle, a quadrangle, etc., the pasting target is rotated. It is configured to press against the suction belt 31 side. The rotation assisting portion 40 is preferably a sponge-like member because of its shape following property, but may have a suitable elastic force and frictional force such as rubber and elastomer. If it is a sponge-like member, it can be rotated smoothly by pushing back with an appropriate reaction force with a simple and inexpensive material without damaging the object. The rotation assisting unit 40 may be urged toward the suction belt 31 by an appropriate force by an elastic member such as a spring provided in the sponge pressing mechanism 41.

  For example, a turntable 50 is provided downstream of the transport belt 11. The turntable 50 is rotated at a low speed by the table motor 51 so that the bin W conveyed by the conveyor belt 11 is temporarily retained. On the turntable 50, it is shipped after confirming whether the two labels L are properly attached to the bin W. The transport belt 11 may be directly connected to the next line instead of being connected to the turntable 50.

  Next, the operation of the label sticking device 1 according to this embodiment will be described.

  First, the label sticking apparatus 1 is turned on. The conveying motor 12 is driven to drive the conveying belt 11 at the first speed V1. Similarly, a suction motor (not shown) is driven to drive the suction belt 31 at the second speed V2. The operator M operates the first labeler control panel 24 and the second labeler control panel 25 to set the label L application position, and also sets the date to be printed by the printer 29. The two labels L may be sent out while being shifted along the advancing direction of the suction belt 31. However, if the labels are shifted up and down, they may be attached to a position overlapping the sending direction.

  Then, the bin W is placed on the conveyor belt 11. While the placed bin W is conveyed at the first speed V1, the separation sensor 15 detects the bin W, and the separation device 14 leaves the appropriate pitch P1 and flows the bin W to the downstream side.

  Next, when the label sending sensor 16 detects the bin W, two different labels L are sent from the first label sending device 20 and the second label sending device 21 from different label rolls 23 respectively. Information such as a date is printed on the label L delivered from the first label delivery device 20 by the printer 29. Then, the two labels L are attached to the suction belt 31 driven at the second speed V2 with an appropriate interval. At this time, the side opposite to the adhesive material of the two labels L is adsorbed to the adsorption belt 31.

  As shown in FIG. 1, the bin W that has been transported before the rotation assist unit 40 rotates on the transport belt 11 while being pressed against the suction belt 31 by the rotation assist unit 40. At this time, the rotation assisting portion 40 is supported while deforming in accordance with the shape of the outer peripheral surface of the bin W, and the adhesive materials of the two labels L are respectively attached to the positions shifted from the outer peripheral surface of the bin W. At this time, even if the bin W has a cross-sectional shape other than a circular cross-section such as a rectangular cross-section, the rotation assisting portion 40 presses the bin W against the suction belt 31 while being appropriately deformed. A label L is affixed. In addition, since two labels L are simultaneously affixed to the outer periphery of the bin W, as in the case where each label L is affixed at different positions, the affixing positions (intervals) of the second and subsequent labels L are reliably controlled. There is no need to do. This is because the distance between the two labels L is determined when the label L is attracted to the suction belt 31.

  Next, the bin W on which the two labels L are pasted stops when it exceeds the region of the rotation auxiliary unit 40, moves on the conveyor belt 11 at the speed V <b> 1, and flows into the turntable 50. Then, the worker M checks whether the two labels L have been properly attached to the bottle W that rotates slowly on the turntable 50, and packs it in a container or flows it to a subsequent process.

  In the present embodiment, since the printing machine 29 is provided on the downstream side of the first label sending device 20 and on the upstream side of the suction belt 31, the printing machine 29 can print characters and the like that change appropriately such as a date on the label. Further, since the label sending device is composed of the two label sending devices 20 and 21, it is easy to provide a printing machine 29 between them, and the surface base material of the label roll 23 on the first label sending device 20 side is a thermal paper. In addition, the surface base material of the label roll 23 on the second label delivery device 21 side can be flexibly handled such as using high-quality paper that is not thermal paper.

  Here, the relationship between the speed V1 and the speed V2 will be described. It is assumed that the bin W has a circular cross section and that no slip occurs between the bin W and the rotation auxiliary unit 40.

First, points a, b, and c are defined as shown in FIG. In this case, the relative speed of the two points a and c is
Vc = Va + Vc / a (1)
Thus, the central speed of the bin W at each position from P1 = P2 becomes the first speed V1, and Va = V1.

  Since the point c theoretically does not slip, Vc = 0.

The vector Vc / a is perpendicular to the vector ac and its direction must coincide with ω. For this reason, when Vc / a is directed in the plus direction and the angular velocity is ω (rad / s), the magnitude thereof is Dω / 2. Substituting this into equation (1) gives
0 = −V1 + Dω / 2.
Therefore, ω = 2V1 / D (rad / s) in the counterclockwise direction.

Since the speed of the suction belt 31 is the speed at the point b,
V2 = Vb = Va + Vb / a = V1 + Dω / 2 = V1 + D / 2 × 2V1 / D = 2V1
Therefore, V2 = 2V1.

  Therefore, according to the label sticking apparatus 1 according to the present embodiment, even if a plurality of labels differing in paper quality or the like, a plurality of labels L can be easily and reliably stuck to the outer peripheral surface of the bin W while smoothly rotating the bin W. Can do.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.

  For example, in the above embodiment, two labels L are attached to the outer periphery of the bin W, but three or more labels may be attached.
