Further, the reversing shaft 22 is rotatably supported by a support member having a lower end portion fixed to the main body frame 60.

  As shown in FIG. 2, the conveyor belt 21 has a configuration in which two belt belts 21a and 21b are arranged in parallel with a predetermined gap in the width direction. The two belt-like belts 21a and 21b are formed in an endless manner so as to span the drive roller, the guide roller, and the reverse shaft 22. The belt-like belts 21a and 21b have the same shape (width dimension, length dimension). Moreover, the belt-like belts 21a and 21b are made of, for example, urethane.

  The endless transport belt 21 is disposed such that a region (label receiving surface 21 </ b> A) that receives the label 1 from the rotating drum plate 11 faces the rotating drum plate 11. Further, the distance between the rotary drum plate 11 and the label receiving surface 21A of the conveyor belt 21 is smaller than the width dimension of the sliding contact portion 32 of the peeling member 31 described later (for example, formed to a width of about 10 mm). ing).

  Here, as the rotating drum plate 11 rotates, the leading end portion of the leading label 1a of the belt-like label body 8 comes into contact with (collides with) the slidable contact portion 32 having an arcuate shape, and the leading label 1a rotates. It peels off from the drum plate 11 and reverses (the adhesive surface (adhesive layer 4) of the leading end portion of the label 1 contacts the label receiving surface 21A of the conveyor belt 21).

  Specifically, when the adhesive layer 4 of the leading label 1a of the strip-shaped label body 8 comes into contact with the sliding contact portion 32 of the peeling member 31, the leading end portion (adhesive layer 4) of the leading label 1 is moved to the rotating roller 31c1, The leading label 1 can be reversed without causing the adhesive layer 4 to adhere to the slidable contact portion 32 by smoothly moving by the rotation of 31c2 and 31c3. In the example shown in FIG. 4, the plate-like base portion 31a and the pair of roller support plates 31b and 31b are configured as separate members, but may be integrated.

  In the present embodiment, the sliding contact portion 32 includes the rotation rollers 31c1, 31c2, and 31c3, but is not particularly limited thereto. A configuration in which the rotation rollers 31c1, 31c2, and 31c3 are not provided in the sliding contact portion 32, for example, the sliding contact portion 32 may be a smooth sliding surface having an arcuate concave shape. Alternatively, a plurality of spheres may be rotatably supported at the front end portion of the peeling member 31 in a state where the spheres are arranged in a circular arc concave shape.

  Next, the label moving mechanism 40 will be described with reference to FIGS. The label moving mechanism 40 is configured to be able to reciprocate between the rotary drum plate 11 and the label receiving surface 21A of the transport belt 21, and to reciprocate in the length direction (X1 direction or X2 direction) of the transport belt 21. A nip plate 41 configured to be movable is provided.

  The label moving mechanism 40 includes a slide mechanism 42 that moves the nip plate 41 in the length direction (X1 direction or X2 direction) of the transport belt 21, and a direction (Y1) that causes the nip plate 41 to be orthogonal to the width direction of the transport belt 21. And a pressing mechanism 43 that presses the label 1 against the conveying belt 21 by the nip plate 41. The nip plate 41 is formed in a flat plate shape that extends from the upper end in the width direction of the conveyor belt 21 to the lower end in the width direction. The nip plate 41 is made of, for example, a metal such as stainless steel or a synthetic resin.

  The slide mechanism 42 includes a guide rail 42a that extends in the length direction on the conveyor belt 21, and a slider 42b that is slidably supported by the guide rail 42a and reciprocates along the guide rail 42a. Support members 42c and 42d provided at both ends of the guide rail 42a restrict the movement of the slider 42b in the X1 direction or the X2 direction. Further, the slide mechanism 42 can reciprocate in the Y1 direction or the Y2 direction shown by the pressing mechanism 43.

  The slider 42b moves in the X2 direction along the guide rail 42a and comes into contact with the support member 42c and stops. As a result, the nip plate 41 held by the slider 42b is disposed at a home position to be described later.

  In addition, the slider 42b holds the nip plate 41 via a holding metal fitting made of an L-shaped metal fitting or the like, so that the slider 42b extends along the guide rail 42a in the length direction (X1). Direction or X2 direction), the nip plate 41 moves together with the moving slide 42b.

  Furthermore, the pressing mechanism 43 includes a holding member 43a that holds the slide mechanism 42, and is configured so that the holding member 43a moves in the Y1 direction or the Y2 direction illustrated in accordance with a control signal from the control unit 70. For example, when an electromagnet 43b is provided and power is supplied to the electromagnet 43b, the electromagnet 43b is pulled by a magnetic force, moves in the “Y1 direction shown”, and stops supplying power to the electromagnet 43b. Move to. In the present embodiment, the holding member 43a is urged in the “Y2 direction shown” by an urging means such as a spring when no magnetic force is generated.

  Here, the label transfer operation from the rotating drum plate 11 to the conveyor belt 21 of the label sticking device of this embodiment will be described with reference to FIGS.

  Initially, a user sets a label sticking apparatus to an initial operation state. Specifically, the user pulls out the strip-shaped label body 8 from the label roll L attached to the roll support portion 9, and the back surface (adhesive layer 4) of the strip-shaped label body 8 is rotated on the rotating drum plate via the rotating roller 13. 11 is temporarily bonded. Then, the user operates the operation unit 80 to drive the rotary drum plate 11 to move the belt-like label body 8 to a predetermined position of the rotary drum plate 11 (in an initial operation state). Stop driving. Here, as shown in FIG. 5A, the initial operation state means that the leading end of the leading label 1 a of the strip-shaped label body 8 temporarily bonded to the rotating drum plate 11 reaches the sliding contact portion 32 of the peeling member 31. It means the state.

  In the initial operation state, as shown in FIG. 5A, the nip plate 41 of the label moving mechanism 40 is stopped at one end (front end) of the peeling member 31 (this end). The position of the nip plate 41 is referred to as “home position”). The nip plate 41 is disposed at a position separated from the rotary drum plate 11 and does not contact the rotary drum plate 11 when moving.

  The initial operation state may be set, for example, by controlling the rotary drum mechanism 10 based on a detection signal from a sensor (not shown). In this case, a sensor is installed in the vicinity of the peeling member 31. This sensor detects a detection signal (initial state detection signal) when the leading end of the leading label 1a of the strip-shaped label body 8 temporarily bonded to the rotating drum plate 11 reaches the peeling portion 32 of the peeling member 31. Is supposed to send. Then, the initial operation state is set by the control unit 70 as follows.

  Specifically, the user pulls out the strip-shaped label body 8 from the label roll L attached to the roll support section 9, temporarily attaches the back surface (adhesive layer 4) of the strip-shaped label body 8 to the rotating drum plate 11, and controls the control section. An initial operation state setting command is input to 70. The control unit 70 starts the rotation of the rotating drum plate 11 when receiving an initial operation state setting command, and stops the operation of the rotating rotating drum plate 11 when receiving an initial state detection signal from the sensor. Thus, the label sticking device is set to the initial operation state.

  When the label sticking device is set to the initial operation state, the user then operates the operation unit 80 to input a driving request. When the operation request is input, the control unit 70 transmits a control signal (operation instruction signal) to the rotating drum mechanism 10 to cause the rotating drum plate 11 to intermittently operate, and for a predetermined time (first time (T1: for example, 0). After rotating the rotating drum plate 11 only for 1 second)), the rotation is stopped. Thereby, the belt-like label body 8 temporarily bonded to the rotary drum plate 11 moves along with the rotary drum plate 11 by a predetermined dimension (moves as shown in FIGS. 5A to 5C). Specifically, as shown in FIGS. 5A to 5C, the leading label 1 a of the strip-shaped label body 8 temporarily bonded to the rotating drum plate 11 is peeled off by the rotation of the rotating drum plate 11. It collides with the slidable contact portion 32 in the shape of a circular arc and peels off from the rotating drum plate 11 and reverses. At this time, the leading end portion of the leading label 1a is pushed out and reversed while the adhesive layer 4 slides (slids) along the “sliding contact portion 32 recessed in an arc shape”. As a result, as shown in FIG. 5C, the leading label 1a peeled off from the rotating drum plate 11 is bent in an arc shape along the sliding contact portion 32, and the tip portion thereof is reversed and reversed. The adhesive layer 4 at the front end is in contact with the transport belt 21. At this time, the subsequent label 1b connected to the leading label 1a moves to the position of the sliding contact portion 32 of the peeling member 31 (position in the initial operation state).

  In the above description, the control unit 70 rotates the rotating drum plate 11 for a predetermined time (first time). However, the rotation amount of the rotating drum plate 11 is controlled by the predetermined time. Instead, a sensor (not shown) detects that the leading end portion of the leading label 1a has reached a predetermined position on the conveyor belt 21 (detects the state of FIG. 5C) and detects from the sensor. The first conveyor belt 11 may be stopped by a signal.

  Next, when the rotating drum plate 11 is stopped, the control unit 70 transmits a control signal (drive command) to the moving mechanism 40, and the nip plate 41 peels off the rotating drum plate 11 and reverses the leading label 1a. The tip portion is pressed against the conveyor belt 21. In the present embodiment, the nip plate 41 is urged in the Y1 direction illustrated. 5C, the leading end portion of the leading label 1a is sandwiched between the nip plate 41 and the conveying belt 21 (the adhesive layer 4 at the leading end portion of the leading label 1a is pressed against the conveying belt 21. )

  Further, the control unit 70 transmits a control signal (operation instruction signal) to the label transport mechanism 20 while the leading end portion of the leading label 1a is held between the nip plate 41 and the transport belt 21, and the transport belt 21 is Move for a predetermined time (second time (T2)). As a result, the nip plate 41 moves from the position shown in FIG. 5C to the position shown in FIG. 6A as the transport belt 21 moves. By this operation, the leading label 1a of the strip-shaped label body 8 temporarily bonded to the rotating drum plate 11 is pulled in the X1 direction by the nip plate 41 and the conveying belt 21. Note that the rear end portion of the leading label 1a temporarily bonded to the rotating drum plate 11 is pushed out while the adhesive layer 4 slides along the “sliding contact portion 32 recessed in an arcuate shape”, like the front end portion of the label 1a. It is reversed and temporarily adhered to the conveyor belt 21.

  Thus, in the present embodiment, the leading end portion of the leading label 1a is peeled off from the rotating drum plate 11 and bent in an arc shape along the sliding contact portion 32, and the leading end portion is reversed and brought into contact with the conveying belt 21. Then, the conveyor belt 21 is moved in the X1 direction while pressing the inverted portion of the nip plate 41 with the conveyor belt 21. Therefore, the adhesive layer 4 can also be moved along the “sliding contact portion 32 that is recessed in an arc shape” with respect to the rear end portion of the leading label 1a that is temporarily bonded to the rotating drum plate 11, and more reliably. The label 1 can be peeled off from the rotating drum plate 11 and transferred to the conveyor belt 21.

  Further, when the leading label 1a moves from the rotary drum plate 11 to the conveyor belt 21 (see FIG. 6A), the control unit 70 transmits a control signal (driving stop command) to the moving mechanism 40. The nip plate 41 is urged toward the rotating drum plate 11 by an urging means (not shown) (biased in the Y2 direction) and moves toward the rotating drum plate 11 (see FIG. 6B). Thereafter, when the control unit 70 transmits a drive signal (control signal) to the label moving mechanism 40, the nip plate 41 moves toward the peeling member 31 and returns to the home position (see FIG. 6C). At this time, the label 1b is arranged at the position of the initial operation state as the “first label” to be transferred next.

  The controller 70 determines that the transfer of the leading label 1a has been completed when a predetermined time (T3) has elapsed since the transmission of the control signal (drive command) to the moving mechanism 40, and moves the nip plate 41. Also good. Alternatively, when the control unit 70 detects that the leading label 1a has been transferred to the transport belt 21 by a sensor (not shown), the control unit 70 determines that the transfer of the leading label 1a has been completed, and moves the nip plate 41. You may do it.

  Next, when the nip plate 41 returns to the home position, the control unit 70 stops the conveyance belt 21 and returns to the process of FIG. That is, the control unit 70 stops the conveyance belt 21 when a second time (T2) has elapsed after transmitting a control signal (operation instruction signal) to the label conveyance mechanism 20. In the above description, the control unit 70 stops the transport belt 21 when the second time (T2) has elapsed after transmitting a control signal (operation instruction signal) to the label transport mechanism 20. This is just an example. For example, a sensor (not shown) is made to detect that the nip plate 41 has returned to the home position, and when the control unit 70 receives a detection signal from the sensor, the conveyance belt 21 is stopped. May be.

  In this way, the labels 1 can be peeled off one by one from the belt-like label body 8 temporarily bonded to the rotating drum plate 11 and securely transferred to the transport belt 21 for transfer. Then, the label 1 moved to the transport belt 21 by the label moving mechanism 40 is temporarily bonded to the transport belt 21 at a predetermined interval. In this state, the label 1 moves together with the conveyor belt 21 toward the reversing shaft 22. It should be noted that the interval between the labels 1 that are temporarily bonded to the conveyor belt 21 may be adjusted to the interval between the adherends W that move on the belt conveyor 200.

  Then, the label 1 temporarily bonded to the transport belt 21 moves together with the transport belt 21 and is peeled off from the transport belt 21 from the label 1 moving at the head at the position of the reverse shaft 22, and the peeled label 1 is transported. When pushed out from the belt 21 and protrudes, the suction mechanism 50 sucks the label 1 from the non-adhesive surface side of the label 1, that is, the overcoat layer 3 side.

  Next, the suction mechanism 50 will be described with reference to FIGS. 3 and 7 to 10. As shown in FIGS. 3, 7 and 8, the suction mechanism 50 includes a main body 51 in which a plurality of intake ports 53 are formed on a flat surface 51a, and a suction machine 52 in which exhaust ports (not shown) are provided. Have. Further, a communication member 54 is provided between the main body 51 and the suction device 52, and external air sucked from the intake port 53 passes through the communication member 54 and is discharged from a discharge port provided in the suction device 52. The

  The suction mechanism 50 is provided in the vicinity of the end of the transport belt 21 in the traveling direction, specifically, at a position protruding from the reversing shaft 22 toward the traveling direction of the transport belt 21. The suction mechanism 50 is provided at a position slightly separated from the label receiving surface 21 </ b> A of the transport belt 21, and is arranged so that the main body 51 is positioned above the belt conveyor 200 (upward in the vertical direction).

  The surface 51a of the main body 51 is formed in a flat plate shape without irregularities, and wrinkles are not generated on the label 1 sucked on the surface 50a. In addition, it is preferable that the air inlets 53 of the main body 51 are formed uniformly throughout the main body 51 so that the label 1 can be sucked evenly.

  The suction machine 52 is provided with a fan and a drive unit inside, and the drive unit operates the fan, thereby sucking outside air from the intake port 53 of the main body 51 and discharging the sucked outside air from the discharge port. Further, the suction port of the suction device 52 may be provided in the suction device 52 itself, or an exhaust duct (not shown) may be attached to the suction device 52 to serve as a discharge port. The suction device 52 does not need to be provided on the label sticking device. The suction device 52 is disposed at a position separated from the label sticking device, and sucks outside air through the communication member 54 formed in a duct shape. May be.

  In addition, the suction device 52 is not limited to the above-described configuration, and may be configured by an intake port, an exhaust port, and a vacuum pump. By rotating the vacuum motor that constitutes the vacuum pump, the outside air can be sucked from the intake port, and the sucked outside air can be discharged from the exhaust port. Further, the suction force can be adjusted by adjusting the number of rotations of the vacuum motor.

  Furthermore, an adjustment mechanism that can adjust the position of the suction mechanism 50 according to the size and shape of the label 1 and the adherend W may be provided. In the present embodiment, the length dimension L1 of the main body 51 of the suction mechanism 50 protruding from the vicinity of the end portion on the traveling direction side of the transport belt 21 toward the traveling direction side of the transport belt 21 is the length dimension L2 of the label 1 in the traveling direction. Adjust to a smaller position. Here, the length dimension L <b> 1 is a length dimension from the axial center of the reversing shaft 22 of the transport belt 21 to the distal end portion 51 b of the main body 51 constituting the suction mechanism 50. Even when the label 1 is sucked by the suction mechanism 50, the label 1 is pushed out in the advancing direction of the transport belt 21 by the transport belt 21 because one end of the label 1 is temporarily bonded to the transport belt 21. As a result, the label 1 is affixed to the adherend W, and the label 1 is reliably affixed by the adherend W.

  Here, the label sticking operation from the suction mechanism 50 of the label sticking apparatus of the present embodiment to the adherend W will be described with reference to FIGS.

  First, the suction machine 52 of the suction mechanism 50 is driven, and a state where the outside air is sucked from the suction port 53 formed in the main body 51 (suction state) is set. At that time, the label 1 temporarily bonded to the transport belt 21 moves together with the transport belt 21 and is peeled off from the transport belt 21 from the label 1 moving at the head at the position of the reversing shaft 22. It is pushed out of the conveyor belt 21 and protrudes. The suction mechanism 50 sucks outside air around the label 1 from the non-adhesive surface side (overcoat layer 3) of the label 1, so that the non-adhesive surface (overcoat layer 3) of the label 1 becomes the surface 51a of the main body 51. It will be in the state where it was stuck on. Here, the back surface of the label 1 (adhesive layer 4) is in a state where it is not temporarily bonded, that is, the back surface of the label 1 (adhesive layer 4) is opened, and the label 1 is transported by the rotating drum plate 11 or transported. The wrinkles generated when the belt 21 is temporarily bonded can be eliminated.

  And as shown in FIG. 9, when the back surface (adhesive layer 4) of the label 1 adheres to the adherend W moving on the belt conveyor 200, the adherend W moves in such a state. The label 1 is attached to the adherend W. In addition, since the back surface (adhesive layer 4) of the label 1 is not temporarily attached to any of them, the label 1 can be reliably attached to the adherend W.

  Further, since the suction mechanism 50 does not require a configuration corresponding to the reversing shaft 22 of the transport belt 21, the suction mechanism 50 can be attached to the label 1 attached on the surface 51a without considering the diameter of the reversing shaft 22. The space between the adherend W can be made as close to “zero” as possible.

  Here, the force (suction force) for sucking outside air around the label 1 from the suction port 53 by the suction device 52 and the force (push output) for the transport belt 21 to push the label 1 in the traveling direction of the transport belt 21 are: It may be adjusted as appropriate so that the adhesive layer 4 of the label 1 becomes smaller than the force of adhering to the adherend W. In this way, the label 1 can be reliably attached to the adherend W by adjusting the suction force of the suction device 52 and the pushing force of the conveyor belt 21.

  The suction mechanism 50 is not limited to the above-described configuration. For example, a plurality of air inlets 58 are formed on a flat surface 56 a and a space S is formed therein, and air is supplied to the main body 56. A compressor (not shown) for supplying compressed air can be formed through the port 57.

  As shown in FIG. 11A, the main body 56 has a plurality of air inlets 58 formed on a flat surface 56 a and an air supply port 57 communicating with the space S inside the main body 56. A spout 59 is provided at the end in the width direction. In addition, a direction adjusting valve 57a is provided at the tip of the air supply port 57, and the direction of the supplied air can be appropriately adjusted according to the position where the jet port 59 is provided. The installation position of the air supply port 57 may be a position where the air supply direction does not oppose the intake port 58. Furthermore, when the air supply port 57 is installed at a position that is perpendicular to the air supply direction, the suction force can be maximized.

  Further, as shown in FIG. 11B, the main body 56 has a front end portion 56b formed in an acute angle shape in a cross-sectional view, and by reducing the size of the front end portion 56b in the thickness direction, the main body 56 becomes a belt conveyor. It is possible to dispose it at a position closer to the adherend W moving on the 200.

  A compressor (not shown) is, for example, a turbine-type compression pump, and supplies air (compressed air) from an air supply port 57. The supplied compressed air passes through the space S formed inside the main body 56, and is ejected from the ejection port 59. Thus, the ejector effect based on Bernoulli's theorem causes the space S inside the main body 56 to be at a pressure lower than the atmospheric pressure. (Negative pressure) state. Since the space S inside the main body 56 is in a negative pressure state, outside air flows into the space S from the intake port 58 formed in the surface 56 a of the main body 56. Then, the label 1 can be sucked onto the surface 56a. The outside air that has flowed into the space S inside the main body 56 is discharged from the jet port 59.

  Since the distal end portion 56b of the main body 56 is formed in an acute angle shape, when the compressed air is supplied to the main body 56 by the compressor, the negative pressure state in the space S varies, so the force for sucking the label 1 is Different states occur at the position of the intake port 58. Here, in order to make the suction force with respect to the label 1 constant, the shape and gradient of the intake port 58 may be adjusted according to the position where the intake port 58 is formed.

  Note that the main body 56 of the suction mechanism 50 of the present embodiment may have a rectangular cross section of the main body 56, for example, and a space having a certain size is formed in the thickness direction. The negative pressure state in the space can be made constant, and the label 1 can be sucked evenly.

  The suction mechanism 50 using the compressor can stick the label 1 to the adherend W in the same manner as the suction mechanism 50 using the suction machine 52.

  As described above, in this embodiment, the peeling member 31 in which the slidable contact portion 32 that is recessed in an arc shape is formed between the rotating drum plates 11a, 11b, 11c, 11d, 11e, 11f, and 11g. Place it so that it is located in the gap. That is, in the present embodiment, by disposing the peeling member 31 in each gap portion of the rotating drum plate 11, the leading end portion (leading label 1) of the strip-shaped label body 8 temporarily bonded to the rotating drum plate 11 is rotated. The drum plate 11 can be peeled off and inverted. As a result, it is possible to provide a label sticking apparatus that peels off the label 1 from the belt-like label body 8 and attaches the label 1 to the adherend W with high accuracy.

  Further, in this embodiment, when the label 1 is transferred from the rotary drum plate 11 to the transport belt 21, the nip plate 41 causes the adhesive surface 4 of the leading end portion of the label 1a that peels off from the rotary drum plate 11 to be reversed to the transport belt 21. Therefore, the label 1 can be temporarily adhered to the transport belt 21 reliably. In addition, the transport belt 21 is moved while the nip plate 41 and the transport belt 21 sandwich the label 1, and the leading label of the strip-shaped label body 8 temporarily bonded to the rotary drum plate 11 is pulled. Compared with the method of Patent Document 2 described above (a method in which the label is transferred from the first conveyor belt to the second conveyor belt by simply bringing the adhesive surface of the leading label of the belt-shaped label body into contact with the second conveyor belt). The label 1 can be transferred from the rotating drum plate 11 to the conveyor belt 21 with high accuracy.

  Furthermore, in this embodiment, the suction mechanism 50 sucks from the non-adhesive surface side of the label 1, and the back surface of the label 1 (adhesive layer 4) is opened, that is, the back surface of the label 1 (adhesive layer 4) Since the wrinkles formed on the label 1 can be eliminated when temporarily adhering to the rotating drum plate 11 or the conveyor belt 21, the wrinkle is not generated on the label 1. It can be attached to the adherend W.

  Moreover, the suction mechanism 50 of this embodiment can make zero between the back surface (adhesive layer 4) of the label 1 and the adherend W moving on the belt conveyor 200 as much as possible. On the other hand, if the label 1 is temporarily attached to the adherend W from the state where the label 1 is temporarily bonded onto the transport belt 21, the transport belt 21 is rotated 180 degrees in order to peel off the label 1 from the transport label 21. Since the reverse shaft 22 is required, at least the shaft diameter of the reverse shaft 22 is separated between the back surface of the label 1 (adhesive layer 4) and the adherend W.

  Further, when the label 1 is temporarily attached to the adherend W from a state where the label 1 is temporarily bonded onto the conveyance belt 21, there is a situation in which the label 1 is not peeled off from the conveyance belt 21 and the conveyance belt 21 entrains the label 1. Assumed, the suction mechanism 50 according to the present embodiment causes the label 1 to be wound in order to attach the label 1 to the adherend W from the state where the back surface (adhesive layer 4) of the label 1 is not temporarily bonded. Can be avoided.

  As described above, according to the present embodiment, the label 1 is peeled off from the strip-shaped label body 8 formed in a strip shape by connecting a plurality of no-separator type labels 1, and the label 1 is pasted on the adherend W with high accuracy. A labeling device to be attached can be provided.

  In addition, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible within the range of the summary.

  The adherend W moves not only when moving on the linear belt conveyor 200 shown in FIGS. 1 and 9, but also when the adherend W moves on the round belt conveyor 201 as shown in FIG. There is. The adherend W moving on the belt conveyor 201 approaches one end of the label applicator of this embodiment and then moves so as to be separated.

  A sticking assist mechanism 90 that rotates the main body 56 of the suction mechanism 50 may be provided in accordance with the adherend W that moves on the belt conveyor 201. In accordance with the adherend W moving on the belt conveyor 201, the label 1 sucked by the main body 56 of the suction mechanism 50 maintains an optimum angle, so that the label 1 can be reliably attached.

  The sticking assist mechanism 90 includes a joint arm 91 attached to the main body 56 of the suction mechanism 50, a support member 92 that rotatably supports the joint arm 91, and the main body 56 of the suction mechanism 50 tilting toward the adherend W side. And an urging member 93 for urging so as to achieve the above state. Here, the state where the main body 56 of the suction mechanism 50 is inclined toward the adherend W side is referred to as a sticking standby state. When the adherend W comes into contact with the main body 56 of the suction mechanism 50 in the sticking standby state, the main body 56 of the suction mechanism 50 rotates in accordance with the movement of the adherend W.

  One end of the joint arm 91 is attached to the main body 56 of the suction mechanism 50, and the other end of the joint arm 91 is rotatably supported by the support member 92. As the joint arm 91 rotates, the main body 56 of the suction mechanism 50 rotates. In the present embodiment, a pivot shaft 91 a is provided at one end of the joint arm 91. The rotation shaft 91a is inserted through a restriction hole 92a formed in the central portion of the support member 92, and the rotation shaft 91a moves along the hole shape of the restriction hole 92a. For example, the hole shape of the restriction hole 92a is formed so that the joint arm 91 rotates within a range of about 10 degrees. The shapes and configurations of the joint arm 91 and the support member 92 can be changed as appropriate.

  The urging member 93 is composed of, for example, a spring. The urging member 93 urges the main body 56 of the suction mechanism 50 to be in a sticking standby state. On the other hand, when the adherend W comes into contact with the main body 56 of the suction mechanism 50, the main body 56 of the suction mechanism 50 rotates by a predetermined angle (about 10 degrees in the present embodiment). Thereafter, the urging member 93 urges the main body 56 of the suction mechanism 50 so as to change from a state where the main body 56 is rotated by a predetermined angle to a sticking standby state. The urging member 93 may be constituted by a drive source such as a drive motor.

  Here, the label sticking operation | movement to the to-be-adhered body W by the sticking auxiliary | assistance mechanism 90 of the label sticking apparatus of this embodiment is demonstrated using FIGS.

  The adherend W is moving on the round belt conveyor 201 shown in FIG. First, the sticking assist mechanism 90 urges the main body 56 of the suction mechanism 50 to be in a sticking standby state, that is, a state inclined to the adherend W as shown in FIG. Further, the label 1 a is pushed out by the conveyor belt 21 and is sucked by the main body 56 of the suction mechanism 50.

  Next, the label 1a is affixed to the adherend W by the abutment of the adherend W on the affixing assisting mechanism 90 that is in a standby state. At that time, as the main body 56 of the suction mechanism 50 rotates in the direction of the arrow C1 shown in FIG. 13A, the rotation shaft 91a of the joint arm 91 has a hole shape of the restriction hole 92a formed in the support member 92. , And the biasing member 93 extends.

  When the main body 56 of the suction mechanism 50 shown in FIG. 13B is in the pasting state, the control unit 70 drives the transport belt 21 so that the next label 1b is the transport belt 21. The label 1b is sucked by the main body 56 of the suction mechanism 50 as shown in FIG.

  Then, when the extended urging member 93 is restored to the original, the rotation shaft 91a of the joint arm 91 follows the hole shape of the restriction hole 92a formed in the support member 92 in the direction of the arrow D2 shown in FIG. As it rotates, the main body 56 of the pulling mechanism 50 rotates in the direction of the arrow C2 shown in FIG. 14, and returns to the sticking standby state shown in FIG. With this configuration, even when the label 1 is attached to the adherend W moving on the round belt conveyor, it is possible to reliably attach the label 1.
