Description

  The present invention relates to a label mounting apparatus for mounting a label having an opening on a container.

  Various label mounting apparatuses for mounting a label having an opening such as a through hole on a container have been proposed. Patent Document 1 discloses an example of a conventional label mounting apparatus. In the label mounting apparatus disclosed in this document, labels having openings are sequentially fed out and mounted on the container from directly above the container conveyed by a conveyor or the like. The opening of the label is used as a part for inserting the upper part of the container.

  When attaching labels to a large number of containers, it is required to store a plurality of labels in a state where they are overlapped in advance and to feed the labels one by one from these labels. In order to attach labels to more containers within a predetermined time, it is necessary to increase the speed at which the labels are fed out. The label may be unjustly deformed depending on how a force acting when feeding the label provided with the opening is applied. When a certain label is fed out, the next label superimposed on the label can be partially exposed from the opening of the label. This may cause an unintended force to act on not only the label to be fed but also the label that should not be fed.

JP 2002-53114 A

  The present invention has been conceived under the circumstances described above, and an object of the present invention is to provide a label mounting apparatus capable of more appropriately feeding a label having an opening.

  A label mounting apparatus provided by the present invention is a label mounting apparatus that mounts a label having an opening on a container, the label storage section storing a plurality of the superimposed labels, and the label storage section. A feeding roller for feeding out the foremost label with one side exposed among the plurality of contained labels, and the feeding rollers are positioned on both sides of the opening in the thickness direction of the label. And a non-contact portion positioned between the pair of contact portions.

  In a preferred embodiment of the present invention, the pair of contact portions are configured to be able to change the distance between each other.

  In a preferred embodiment of the present invention, the pair of contact portions is made of a high friction shape or a high friction material.

  In a preferred embodiment of the present invention, the feeding roller has a roller shaft that holds the pair of contact portions, and at least one of the pair of contact portions is movable and fixed with respect to the roller shaft. It is possible.

  In preferable embodiment of this invention, the said label accommodating part is accommodated in the state in which the thickness direction of the said several label followed the perpendicular direction, and the said frontmost label is located in the lowest order. .

  In preferable embodiment of this invention, the said label accommodating part is further equipped with the press member which provides the force which presses down what is located in the highest rank among these labels from upper direction to the downward direction.

  According to the present invention, when the label is fed out from the label feeding device, the pair of contact portions of the feeding roller abuts on both side portions of the opening of the frontmost label. The non-contact portion of the feeding roller is provided at a position facing the opening of the label. For this reason, when the previous label is fed out, the feeding roller does not contact the next label even if the label is displaced in the transport direction and the next label is exposed from the opening. For this reason, it is possible to reliably feed out only the foremost label, and it is possible to prevent the next label from being unintentionally fed out. In addition, in order to feed out the label provided with the opening in the center, the configuration in contact with both side portions of the opening is less likely to unduly distort the label, and the label has an appropriate shape. It is possible to pay out as it is. Therefore, according to the label mounting apparatus, the label having the opening can be fed out more appropriately.

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

  FIG. 1 shows a label mounting apparatus according to a first embodiment of the present invention. The label mounting device A1 according to the present embodiment includes a container transport device 12, a label feeding device 20, a label breaking device 60, a label delivery device 70, and a label pressing device 110. The label mounting device A1 is a device for mounting the label L on the container B. In the figure, the z direction is the vertical direction. Further, the label pressing device 110 is employed with the intention of more reliably performing the label L on the container B, but the label pressing device 110 is not a device that forms the basis for label mounting, but is selected as necessary. The label pressing device 110 may be provided without the label pressing device 110. Such a configuration is preferably employed when reliable mounting can be expected without using the label pressing device 110 according to, for example, the shape and mounting state of the container B and the label L.

  The specific configuration of the container B is not particularly limited, and examples include a bottle-shaped container such as a PET bottle, a container with a pump containing a shampoo, a pharmaceutical container (such as an ampoule and a vial), and other various shapes. Various containers such as a resin container, a metal container, and a glass bottle may be used.

  FIG. 2 illustrates a label L used in the label mounting apparatus A1. FIG. 2A is a plan view showing an example of the label L. FIG. The label L is a neck label attached to the neck of the container B as shown in FIG. 4, and has a substantially rectangular shape in which four corners are formed in an arc shape. The label L is formed of, for example, a sheet material such as synthetic resin, paper, cardboard, and synthetic paper, a laminate of these, a laminate of these and other sheets, and the like. The surface of the label L (that is, the surface facing away from the container shoulder when the container is mounted) and the back surface are printed with characters, graphics, background colors, etc., and display information for consumers who purchase the product can do.

  In the label L of this example, an opening 2 and a perforation line 3 are formed. The opening 2 is a part constituting a space that penetrates the label L in the thickness direction. In the illustrated example, a through hole 2 a is shown as a specific example of the opening 2. The through-hole 2a is provided in the approximate center of the label L, and has an oval shape (or a track shape), for example. The perforation line 3 is provided to partially break the label L. In the illustrated example, the perforation line 3 includes a part extending in the x direction connected to the through hole 2a and a part extending from the part to both sides in the y direction. However, the shape of the perforation line 3 is not particularly limited. The perforation line 3 is a line that is broken before the label L is attached to the container B by a label breaking device 60 described later.

  A portion of the label L sandwiched between the perforation lines 3 on both sides in the y direction of the through hole 2 a is an engaging portion 4. The engaging portion 4 is a part for preventing the label L from being detached from the container B when the label L is attached to the container B. The engaging part 4 also functions as a display part by abutting on the container B and standing up.

  FIG. 2B shows another example of the label L. The label L of this example is an example including the through hole 2 a and the plurality of cutting lines 2 b as the opening 2. The cutting line 2b is a linear part that does not have a clear area in plan view, but is an example of a part that forms a space that penetrates the label L in the thickness direction. That is, the cutting line 2b constitutes the opening 2 that clearly appears on the appearance of the label L in the same manner as the through-hole 2a when a force is applied to the label L or when it is deformed. In this example, the portion between the plurality of cutting lines 2 b is the engaging portion 4. The label L of this example does not have a perforation line or the like that is broken by the label breaking device 60. Thus, the label mounting apparatus A1 is an apparatus that appropriately feeds the label L formed with the opening 2, and the perforation line 3 may or may not be provided in the label L.

  FIG. 2C shows still another example of the label L. In the label L of this example, only a plurality of cutting lines 2 b are formed as the opening 2. In the illustrated example, the plurality of cutting lines 2b form an H-shape, but the arrangement of the cutting lines 2b is not particularly limited. Thus, even if it is the label L in which the through-hole 2a is not formed as the opening part 2, it can mount | wear with the container B through the below-mentioned process.

  2A, 2B, and 2C, the label L has four corners formed in an arc shape, but the corners may be substantially right angles, A part may be partly cut out, and can have various shapes. When such a label L is attached to the neck portion of the container B, the tongue-shaped engagement portion 4 of the label L is pressed against the container B, so that the attachment state of the label L becomes stable. In the following description, a case where the label L shown in FIG.

  The container transport device 12 continuously transports a container B such as a PET bottle in the x direction, for example. The container transport device 12 can be configured by a belt conveyor or the like that moves the container B in the container transport direction along the x direction while placing the container B thereon. The container transport device 12 has a pair of bars 14a and a pair of bars 14b. The pair of bars 14a guides the container B from both sides in the x direction and the y direction perpendicular to the z direction. The pair of bars 14b is provided below the pair of bars 14a in the z direction, and guides the container B from both sides in the y direction. Unlike the present embodiment, a configuration having only a pair of bars may be used. Further, the container transport device 12 may include a plurality of pairs of positioning guides that move in synchronization with the belt conveyor.

  The label feeding device 20, the label breaking device 60, the label delivery device 70, and the label transport device 80 are installed side by side in the x direction above the container transport device 12 in the x direction. Further, the label pressing device 110 is installed on the downstream side with respect to the label transport device 80 in the container transport direction (x direction).

  The label feeding device 20 is a device that feeds the labels L one by one toward the label breaking device 60. As shown in FIG. 1 and FIGS. 5 to 7, in the present embodiment, the label feeding device 20 includes a label accommodating portion 22, a feeding roller 24, support rollers 31 and 32, and a support shaft 33. When the label breaking device 60 is not provided, the label feeding device 20 may be configured to feed the label L to the label delivery device 70 or the label transport device 80, for example.

  The label accommodating portion 22 accommodates a plurality of stacked labels L. In the present embodiment, the plurality of labels L are stacked in a state where the thickness direction is along the z direction, which is the vertical direction, and is accommodated in the label accommodating portion 22 in this state. A feeding opening 28 is formed in the label accommodating portion 22. The feeding opening portion 28 is a portion that opens at the lower end in the z direction of the label housing portion 22. From this feeding opening portion 28, one side of the lowest label among the plurality of labels L accommodated in the label accommodating portion 22 is exposed. In the present embodiment, the label L positioned at the lowest is the frontmost label L that is fed out next. In the present embodiment, the lower part of the label accommodating portion 22 in the z direction is configured to be displaced forward in the x direction as the plurality of labels L move downward in the z direction. Thereby, since the label L adjacent vertically is shifted in the x direction, the degree of adhesion between the labels L is reduced. As a result, the operation of feeding out the labels L one by one can be performed more reliably.

  The support rollers 31 and 32 and the support shaft 33 are disposed immediately below the label housing portion 22 and partially cover the feeding opening portion 28 of the label housing portion 22. The support rollers 31 and 32 and the support shaft 33 can be rotated by being supported on the side wall of the label accommodating portion 22 via a rolling bearing, for example. The support roller 31 and the support roller 32 are arranged side by side in the x direction. The support shaft 33 has a smaller diameter than the support rollers 31 and 32, and is disposed in a narrow gap between the support roller 32 and the feeding roller 24. In the illustrated example, all of the support rollers 31 and 32 and the support shaft 33 are arranged, but this is an example of a configuration example. One or more of the support rollers 31 and 32 and the support shaft 33 may be selected and employed depending on the size and shape of the label L and the state of feeding by the feeding roller 24. As a suitable configuration example for feeding the label L, a configuration including only the support roller 31 can be cited. In such a configuration, the ratio of the weights of the plurality of labels L applied to the feeding roller 24 is increased, and it can be expected that the feeding force by the feeding roller 24 is increased. In this example, the case where the support rollers 31 and 32 and the support shaft 33 are rotatable has been described. However, the support shaft 33 may be configured to be non-rotatable. Further, a vibration device (not shown) may be attached to the label accommodating portion 22. By applying vibration to the label L in the label housing portion 22 by the vibration device, air enters between the labels L, and a plurality of labels L are prevented from being sent out from the label housing portion 22 at the same time.

  The feeding roller 24 is for feeding the lowest (frontmost) label L in the x direction. The feeding roller 24 has a roller shaft 241, a pair of contact portions 242 and a non-contact portion 244.

  The pair of contact portions 242 are separated from each other in the y direction, and are located on both sides of the through-hole 2a of the label L at the lowest position (frontmost) of the label accommodating portion 22. The diameter of the contact portion 242 is a size that is in contact with the lowest-order (frontmost) label L at least in a state where the label mounting apparatus A1 operates. In the present embodiment, the pair of contact portions 242 are made of separate members, and are fixed to the roller shaft 241 by a pair of fixing blocks 245. The pair of fixed blocks 245 are fixed to the roller shaft 241 by fastening bolts, for example, and can be moved in the y direction with respect to the roller shaft 241 by loosening the bolts. Thereby, the y-direction position with respect to the roller shaft 241 of the pair of contact portions 242 can be adjusted. Note that the position of only one of the pair of contact portions 242 may be adjustable with respect to the roller shaft 241. The material of the contact portion 242 is not particularly limited, and a high friction material such as resin and rubber or a metal such as aluminum can be used as appropriate. From the viewpoint of not causing significant wear even after the contact portion 242 comes into contact with the plurality of labels L, the contact portion 242 is preferably made of metal, and the surface is preferably cured by surface treatment or the like. is there.

  In the present embodiment, a plurality of protrusions 243 are formed on the peripheral surface of the contact portion 242. The plurality of protrusions 243 are an example of the high friction shape of the present invention. Each of the plurality of projections 243 is, for example, a projection having a pyramid shape (a quadrangular pyramid shape). The plurality of protrusions 243 are arranged in a matrix along the axial direction and the circumferential direction of the feeding roller 24. By providing the protrusions 243, the force for feeding the label L by the feeding roller 24 can be increased.

  The non-contact part 244 is provided between the pair of non-contact parts 244 and is a part that does not contact the lowest (frontmost) label L. In the present embodiment, the non-contact portion 244 is configured by a portion located between the pair of contact portions 242 in the roller shaft 241.

  The feeding roller 24 is preferably driven to feed the label L. In this embodiment, the feeding roller 24 is driven by a motor 249 connected to the roller shaft 241.

  As shown in FIGS. 1 and 8, the label breaking device 60 is disposed adjacent to the downstream side of the guide plate 44 in the x direction. The label breaking device 60 functions to break the perforation line 3 when the perforation line 3 is formed on the label L. The label breaking device 60 includes a transfer roller 62 and a breaking roller 64. One of the transfer roller 62 and the breaking roller 64 is connected to a motor (not shown) and is driven to rotate in the direction of the arrow in the figure, and the other of the transfer roller 62 and the breaking roller 64 is connected to the driving roller with a gear and driven to rotate. Can be configured as a driven roller.

  The transfer roller 62 includes a shaft 63 and two nip rollers 66 fixed on the shaft 63 at a predetermined interval. It is preferable that at least the outer peripheral surface of the nip roller 66 is formed of a high friction material such as rubber that is difficult to slip with respect to the label L.

  The breaking roller 64 has a shaft 65 disposed in parallel with the shaft 63 of the transfer roller 62 and a transfer breaking roller portion 68 fixed on the shaft 65. At least the outer peripheral surface of the transfer breaking roller portion 68 is preferably formed of a high friction material such as rubber which is difficult to slip with respect to the label L, like the nip roller 66.

  The transfer break roller portion 68 has a pair of transfer portions 681 and a break portion 682. The pair of transfer portions 681 are arranged separately on both sides in the y direction, and in the illustrated example, has a perfect circular shape with a constant outer shape. The breaking portion 682 is provided between the pair of transfer portions 681. The breaking portion 682 has a shape in which a part in the circumferential direction protrudes radially outward from the pair of transfer portions 681. Of the fracture portion 682, the portion other than the protruding portion has a partial circular shape that is the same shape as the transfer portion 681.

  The label delivery device 70 includes, for example, conveyance belts 71 and 72. The conveyor belts 71 and 72 are endless belt members that are rotationally driven while being in contact with each other. The label delivery device 70 includes a pair of conveying belts 71 and 72 that are spaced apart from each other in the y direction. In FIG. 1, only the conveyor belts 71 and 72 on one side in the y direction are shown. The transport belts 71 and 72 move the label L received from the label breaking device 60 toward the label transport device 80 while sandwiching both side portions of the through-hole 2a of the label L.

  The label delivery device 70 includes first and second sensors (not shown). The first sensor detects the label L at a predetermined position and transmits a label detection signal to a control unit (not shown). The control unit that has received the label detection signal drives and controls the conveyor belts 71 and 72 to move the label L to the downstream end and wait. The second sensor detects the position of the container B at a predetermined position and transmits a container detection signal to the control unit. The controller that has received the container detection signal drives and controls the upper and lower transport belts 71 and 72 to deliver the label L waiting at the downstream end to the label transport device 80 at a timing at which the container B can be mounted. It is like that. With these first and second sensors, the label L can be attached to the container B even when the pitch between the containers B being conveyed is not a constant pitch.

  The label conveying device 80 is a device that conveys the label L delivered from the label delivery device 70 at the label receiving position α to the label mounting position β. The label conveying device 80 of this embodiment includes a pair of endless belt members 81, a plurality of pulleys 82, a pair of low-pressure chambers 87, and a pair of belt facing members 91. FIG. 9 is a bottom view of the label conveyance device 80 as viewed from below in the z direction.

The pair of low pressure chambers 87 are spaced apart in the y direction. The low pressure chamber 87 is set so that the internal space has a lower atmospheric pressure than the outside. Each low pressure chamber 87 is made of a material such as resin or metal. The low pressure chamber 87 extends obliquely from the label receiving position α to the label mounting position β. The low pressure chamber 87 is open on the lower side. The lower opening of the low-pressure chamber 87 is closed by an endless belt member 81 that moves from the label receiving position α to the label mounting position β. The low pressure chamber 87 is connected to a vacuum pump (not shown), for example. By operating the vacuum pump, the air pressure in the internal space of the low pressure chamber 87 becomes lower than the external pressure.
Be held.

  A pair of pulleys 82 is disposed on both sides of the low pressure chamber 87 in the x direction. One of the pair of pulleys 82 is driven by a motor (not shown). Alternatively, the endless belt member 81 may be driven by driving means other than the pair of pulleys 82. The endless belt member 81 is wound around a pair of pulleys 82 and closes the lower opening of the low pressure chamber 87. A plurality of suction holes 811 are formed in the endless belt member 81. The plurality of suction holes 811 are, for example, circular or elliptical, and are arranged in the longitudinal direction of the endless belt member 81.

  The pair of belt facing members 91 are disposed to face the lower surfaces 83 of the pair of endless belt members 81. Each belt facing member 91 is made of metal, resin, or the like. The belt facing member 91 is disposed substantially parallel to the lower surface 83 of the endless belt member 81. The gap between the belt facing member 91 and the lower surface 83 of the endless belt member 81 is larger than the thickness of the label L, and preferably slightly larger than the thickness of the label L.

  In this example, the case where the belt facing member 91 is disposed substantially parallel to the lower surface 83 of the endless belt member 81 has been described. However, the belt facing member 91 is disposed on the lower surface 83 of the endless belt member 81 in the z direction. And may not be disposed substantially parallel to the lower surface 83 of the endless belt member 81.

  As shown in FIGS. 1, 10, and 11, the label pressing device 110 presses the label L against the container B when or immediately after the label L transported by the label transporting device 80 is attached to the container B. Device. In FIG. 10, the bars 14a and 14b are not shown. The following description describes the configuration when the label pressing device 110 is employed, and when the label L can be reliably attached to the container B without using the label pressing device 110 as described above. A configuration without the label pressing device 110 is preferable.

  The label pressing device 110 includes a pressing member 111 and a support portion 115. The pressing member 111 has a U-shaped cross section and opens downward. The pressing member 111 has a pair of side wall portions 130 that are spaced apart in the width direction. The distance between the pair of side wall portions 130 is longer than the diameter of the head portion C of the container B and shorter than the diameter of the cylindrical body portion of the container B. A pressing portion 131 is provided below each side wall portion 130. The pressing portion 131 has a guide portion that extends obliquely downward from the upstream side to the downstream side, and a horizontal direction extending portion that extends substantially parallel to the X direction from the downstream end portion of the guide portion. The upstream end portion of the lower surface of the guide portion is located above the lower end position of the head C of the container B. Further, the lower surface of the horizontal extending portion is disposed at substantially the same height as the lower end of the engaging portion 4 of the label L mounted at a predetermined position of the container B. Even if the label L is mounted at a position higher than the predetermined position of the container B, the engaging portion 4 of the label L is pressed to the predetermined position by the horizontal extending portion by the configuration of the pressing portion 131. Thereby, the label L is attached to a predetermined position of the container B.

  The support part 115 is a part that supports the pressing member 111, and has a horizontal part 135 and a vertical part 136 in the illustrated example. The horizontal part 135 is a part extending in the horizontal direction, and the vertical part 136 is a part extending in the vertical direction from the horizontal part 135. In the illustrated example, the pressing member 111 is attached to the support portion 115 via the hanging portion 117 and the adjustment mechanism 120. The hanging part 117 is a part that supports the pressing member 111 so as to be suspended. The adjusting mechanism 120 is interposed between the vertical portion 136 and the hanging portion 117 and adjusts the position in the z direction of the hanging portion 117 with respect to the vertical portion 136.

  Next, the mounting of the label L by the label mounting apparatus A1 will be described below.

  As shown in FIGS. 1 and 5 to 7, when the feeding roller 24 is rotationally driven in the label feeding device 20, a plurality of contact portions 242 of the feeding roller 24 are accommodated in the plurality of label housing portions 22. An attempt is made to move the lowermost (frontmost) label L among the labels L in the x direction. At this time, as shown in FIG. 7, in the lowest-order (frontmost) label L, the pair of contact portions 242 are brought into contact with both side portions of the through-hole 2 a as the opening portion 2 in the y direction. As a result, the hatched belt-like portion in FIG. 7 is scraped out by the pair of contact portions 242, and the lowest-order (frontmost) label L is fed out. Note that in the feeding out of the label L, the through-hole 2a of the label L and the portions located on both sides in the x direction of the through-hole 2a are opposed to the non-contact portions 244 of the feeding roller 24. 24 does not contact.

  Next, as shown in FIGS. 1 and 8, the fed-out label L is guided to the label breaking device 60. The label L is transferred in the x direction while the both sides of the through hole 2a in the y direction are sandwiched between the nip roller 66 and the transfer portion 681. At this time, since the breaking portion 682 is provided in the transfer breaking roller portion 68, the breaking portion 682 is pressed against the central portion of the label L. Thereby, the perforation line 3 of the label L is broken, and the insertion part 2A shown in FIG. 3 is formed. Moreover, the engaging part 4 will stand in the z direction. The broken label L is transferred to the label delivery device 70.

  The label delivery device 70 to which the broken label L has been transferred transfers the label L to the label receiving position α. Using the first sensor and the second sensor provided in the label delivery device 70, for example, the label L transferred by the label delivery device 70 and the container B conveyed by the container conveyance device 12 at the label reception position α. , In the x direction. Thereby, the label delivery apparatus 70 delivers the label L to the label conveyance apparatus 80 at a timing at which the label L can be attached to the container B being conveyed in the x direction.

  The label transport device 80 transports the label L received from the label delivery device 70 at the label receiving position α to the label mounting position β. When the internal space of the low pressure chamber 87 is set to a negative pressure, the label L is adsorbed to the adsorption hole 811 on the lower surface of the endless belt member 81 at the label receiving position α. In this state, the label L is conveyed from the label receiving position α to the label mounting position β by driving the pair of endless belt members 81 by the pulley 82. When transporting the label L to the label mounting position β, the pair of endless belt members 81 suck and hold both side portions of the label L in the y direction of the through hole 2a. As a result, the engaging portion 4 does not receive a force from the endless belt member 81, and the habit of tilting upward from the engaging portion 4 is maintained.

  When the broken label L is conveyed obliquely downward at the label mounting position β, the label L approaches the head C of the container B being conveyed in the z-direction position. Then, as shown in FIG. 4, the insertion portion 2 </ b> A formed by breaking the perforation line 3 is inserted into the head C of the container B. As a result, the label L is mounted around the neck portion of the container B that is located below the head C.

  At the label attachment position β, the label L attached to the container B is transferred to the label pressing device 110 by being conveyed in the x direction together with the container B. In the label pressing device 110, as shown in FIGS. 1, 10, and 11, when the container B moves in the x direction, the label L is pushed down in the z direction by the pressing portion 131. Then, the label L is attached to a predetermined position of the container B by the label L coming into contact with the horizontal portion of the pressing portion 131. The label L can be attached to the plurality of containers B by continuously executing the above steps for the containers B that are sequentially conveyed.

  Next, the operation of the label mounting device A1 will be described.

  According to the present embodiment, when the label L is fed out from the label feeding device 20, the pair of contact portions of the feeding roller 24 is provided on both side portions of the through hole 2 a (opening portion 2) of the lowermost (frontmost) label L. 242 contacts. A non-contact portion 244 of the feeding roller 24 is provided at a position facing the through hole 2a of the label L. For this reason, when the lowermost (frontmost) label L is fed out, even if this label L is displaced in the x direction and the next label L is exposed from the through hole 2a, the feeding roller 24 is placed on the next label L. Does not touch. For this reason, it is possible to reliably feed out only the lowest (frontmost) label L, and to prevent the next label L from being unintentionally fed out. Further, in order to feed out the label L provided with the through-hole 2a in the center, the configuration in contact with both side portions of the through-hole 2a is less likely to unduly distort the label L, and the label L has an appropriate shape. It is possible to pay out as it is. Therefore, according to the label mounting apparatus A1, the label L having the through hole 2a can be fed out more appropriately.

  In the present embodiment, the pair of contact portions 242 are made of different members and are movable with respect to the roller shaft 241. Thereby, when feeding out the label L from which the position and magnitude | size of the through-hole 2a differ, it is possible to adjust beforehand a pair of contact part 242 so that it may be located in the y direction both sides of the through-hole 2a. Therefore, various types of labels L can be handled.

  By providing a plurality of protrusions 243 on the contact portion 242, the contact force between the contact portion 242 and the label L can be further increased. This is preferred for the reliable delivery of the label L.

  In the present embodiment, among the plurality of stacked labels L, the lowest label L is the frontmost label L that should be fed out. For this reason, when the lowest (frontmost) label L is fed out, the other labels L are lowered by gravity, and the next label L quickly becomes the lowest (frontmost) label L. This is suitable for feeding out a plurality of labels L smoothly and sequentially.

  12 and 13 show a modification of the present invention. In these drawings, the same or similar elements as those of the above embodiment are denoted by the same reference numerals as those of the above embodiment.

  FIG. 12 shows a modification of the feeding roller 24. In this modification, the pair of contact portions 242 and the non-contact portion 244 are formed by an integral member. Also according to such a modification, the label L can be properly fed out by bringing the pair of contact portions 242 into contact only with both sides of the through hole 2a of the label L.

  FIG. 13 shows a modification of the label feeding device 20. In this modification, a weight 29 is provided in the label feeding device 20. The weight 29 is made of, for example, metal or resin, and applies a force from the upper side to the lower side of the uppermost label L among the plurality of labels L, and is an example of the pressing member of the present invention. In this modification, even when a plurality of labels L accommodated in the label accommodating portion 22 become a small number as shown in FIG. 13, for example, as shown in FIG. In addition to the weight of the plurality of labels L, a pressing force from the weight 29 is applied. Thereby, the contact force between the lowest label L and the pair of contact portions 242 of the feeding roller 24 can be increased. Therefore, even when the number of the plurality of labels L accommodated in the label accommodating portion 22 is reduced, it is possible to appropriately feed out the lowest label L. This contributes to reducing the frequency of the operation of replenishing the label feeding device 20 with a plurality of labels L when the labels L are attached to a large number of containers B.

  The label mounting apparatus according to the present invention is not limited to the above-described embodiment. The specific configuration of each part of the label mounting apparatus according to the present invention can be varied in design in various ways.

  The feeding roller 24 is not limited to the configuration arranged below the label accommodating portion 22 in the z direction. For example, in a configuration in which the uppermost label L among the plurality of labels L stacked in the label accommodating portion 22 is handled as the foremost label L, the feeding roller 24 is disposed above the label accommodating portion 22 in the z direction. Also good. In this case, it is preferable to provide a mechanism for lifting the plurality of stacked labels L upward in the z direction.
