The belt-shaped belts 21an (n = 1, 2, 3, 4, 5, 6, 7) are arranged to face each other so as to have the same height. Further, the traveling direction of the second transport belt 21 on the label receiving surface 21 </ b> A is opposite (opposite direction) to the traveling direction of the first transport belt 11 on the label peeling surface 11 </ b> A of the first transport belt 11.

With this configuration, in this embodiment, since the peeling member 31 described later can be installed in each gap portion (a plurality of gap portions formed) of the first conveyance belt 11 and the second conveyance belt 21, the first conveyance belt 11 can be more reliably used. The leading end portion (leading label 1) of the strip-shaped label body 8 temporarily bonded to the transport belt can be peeled off from the first transport belt 11 and inverted.

Further, the second belt mechanism 20 is arranged so that the traveling direction of the second conveyor belt 21 toward the reversing shaft 25 is the same direction as the traveling direction of the belt conveyor 200 (a direction that is not the opposite direction). The second conveyor belt 21 is arranged so that the reversing shaft 25 is located above the belt conveyor 200 (above in the vertical direction). It is desirable to set the angle θ formed by the traveling direction of the belt conveyor 200 and the traveling direction of the second transport belt 21 toward the reversing shaft 25 to an acute angle (for example, θ = 15 ° to 45 °). In the present embodiment, the moving speed of the second conveyor belt 21 and the moving speed of the belt conveyor 200 are set to be the same speed.

In this embodiment, the traveling direction of the second conveyor belt 21 is reversed by approximately 180 degrees by the reversing shaft 25. As a result, the label 1 temporarily bonded to the second transport belt 21 moves together with the second transport belt 21 and is peeled off from the head of the label 1 at the position of the reversing shaft 25, and the label 1 is peeled off from the second transport belt 21. It is pushed out from 21 and protrudes. Then, the back surface (adhesive layer 4) of the label 1 protruding from the second conveyor belt 21 adheres to the adherend W moving on the belt conveyor 200, and the adherend W moves in this state. The label 1 is attached to the adherend W.

Next, the label peeling mechanism 30 will be described with reference to FIGS. The label peeling mechanism 30 includes a plurality of peeling members 31 (six peeling members 31 in the illustrated example) and a rod-like support member 35 that supports the peeling members 31. The support member 35 is attached to the main body frame 50 (stands up from the main body frame 50).

Further, the peeling member 31 is formed with a sliding contact portion 32 having a concave shape in a substantially arc shape at one end portion (front end portion) (see FIGS. 2 and 7). Each of the plurality of peeling members 31 is disposed such that the sliding contact portion 31 straddles the label peeling surface 11A of the first transport belt 11 and the label receiving surface 21A of the second transport belt 21 (see FIG. 4-6).

Specifically, the peeling member 31 has one end portion in the width direction of the slidable contact portion 32 inserted into a gap portion formed on the label peeling surface 11 </ b> A of the first transport belt 11 and the other end portion in the width direction of the slidable contact portion 32. Is inserted into a gap formed on the label receiving surface 21A of the second conveyor belt 21 so that the sliding contact portion 32 is connected to the label peeling surface 11A of the first conveyor belt 11 and the label receiving surface of the second conveyor belt 21. It is arranged so as to straddle the surface 21 </ b> A, and is supported by the support member 35. The support member 35 is erected between the label peeling surface 11A and the label receiving surface 21A (see FIG. 6).
With this configuration, the leading end portion of the leading label 1a of the strip-shaped label body 8 moving together with the first conveying belt 11 comes into contact with (collides with) the sliding contact portion 32 having an arcuate shape, and the leading label 1a is It peels off from the first conveyor belt 11 and reverses (the adhesive surface (adhesive layer 4) of the leading end portion of the label 1 comes into contact with the label receiving surface 21A of the second conveyor belt 21).

Further, in the peeling member 31 of the present embodiment, a plurality of rotating rollers 31c1, 31c2, 31c3, and 31c4 are rotatably mounted inside a sliding contact portion 32 that is recessed in an arc shape (see FIG. 7). . In addition, the plurality of rotating rollers 31c1, 31c2, 31c3, and 31c4 are arranged so that the outer peripheral portions thereof are in a shape recessed in an arc shape. In the present embodiment, the number and shape of the rotating rollers 31c1, 31c2, 31c3, and 31c4 are not particularly limited, but are configured as shown in FIG.

In the example shown in the figure, the peeling member 31 is attached to a pair of roller support plates 31b and a pair of roller support plates 31b attached so as to sandwich the front and back surfaces on the front end side of the plate base 31a. It has disk-shaped rotation rollers 31c1, 31c2, 31c3, and 31c4 that are rotatably held.

Specifically, the plate-like base 31a has an arc-shaped recess 31a1 formed at the front end. The roller support plate 31b has an arcuate recess 31b1 at the front end. Then, one (or the other) roller support plate 31b of the pair of roller support plates 31b is disposed in a state in which the recess 31b1 of the roller support plate 31b protrudes from the recess 31a1 of the plate-like base portion 13a. It is fixed to one surface (or the other surface) on the front end side of 31a with a screw or the like. The rotating rollers 31c1, 31c2, 31c3, and 31c4 are arranged in an arc shape along the concave portion 31b2 of the pair of roller support plates 31b, and are rotatably supported by the pair of roller support plates 31b. In this embodiment, the slidable contact portion 32 is configured by the recess 31b1 of the pair of roller support plates 31b and the outer peripheral surfaces of the rotating rollers 31c1, 31c2, 31c3, and 31c4. In addition, the peeling member 31 can be formed with metals, such as stainless steel, for example.

With this configuration, 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. , 31c2, 31c3, and 31c4 can be moved smoothly, and the leading label 1 can be reversed without adhering the adhesive layer 4 to the sliding contact portion 32. In the example shown in FIG. 7, the plate-like base 31 a and the pair of roller support plates 31 b are configured as separate members, but may be integrated.

In this embodiment, the sliding contact portion 32 includes the rotation rollers 31c1, 31c2, 31c3, and 31c4, but is not particularly limited thereto. A configuration in which the rotation rollers 31c1, 31c2, 31c3, and 31c4 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 label peeling surface 11A of the first transport belt 11 and the label receiving surface 21A of the second transport belt 21, and the length direction of the second transport belt 21 The nip plate 41 is configured to be reciprocally movable. FIG. 5 shows a state in which the first moving mechanism 10 is removed to show the nip plate 41 of the label moving mechanism 40. Further, in FIG. 5, a part of the configuration on the lower side of the label moving mechanism 40 (second moving mechanism 40B) is omitted in order to make the drawing easy to see.

As shown in FIG. 5, the label moving mechanism 40 is a first disposed on the upper side (one side in the width direction) of the “first transport belt 11 (not shown in FIG. 5) and the second transport belt 21”. 40 A of moving mechanisms, the 2nd moving mechanism 40B arrange | positioned below (the width direction lower side) of "the 1st conveying belt 11 and the 2nd conveying belt 21", and the 1st moving mechanism 40A and the 2nd moving mechanism 40B And a nip plate 41 supported by both of them. The first moving mechanism 40A is installed on the upper lid 51, and the second moving mechanism 40B is installed on the main body frame 50. The nip plate 41 is formed in a flat plate shape that extends from the upper end in the width direction of the first transport belt 11 (and the second transport belt 21) to the lower end in the width direction. The nip plate 41 is made of a metal such as stainless steel or a synthetic resin, for example.

Further, the first moving mechanism 40A and the second moving mechanism 40B have the same configuration, and each component of the first moving mechanism 40A is opposed to a corresponding component of the second moving mechanism 40B. Is arranged.

Specifically, the first moving mechanism 40A (and the second moving mechanism 40B) includes a slide mechanism 42 that moves the nip plate 41 in the “length direction of the second transport belt 21 (X direction in the drawing)”, and There is provided a pressing mechanism 43 that moves the nip plate 41 in a “direction perpendicular to the width direction of the second conveying belt 21 (Y direction in the drawing)” and presses the label 1 against the second conveying belt 21 by the nip plate 41. Yes.

The slide mechanism 42 includes a guide rail 42a extending in the length direction of the “first transport belt 11 and the second transport belt 21”, and a slider that is slidably supported by the guide rail 42a and reciprocates along the guide rail 42a. (Box-like moving body) 42b, a box-like support member 42c1 that supports one end (the peeling member 31 side) of the guide rail 42a, and a box that supports the other end (the reverse shaft 25 side) of the guide rail 42a And a frame portion 42d for holding the support member 42c1 and the support member 42c2. The frame portion 42d is formed in a U shape in plan view, and spans the upper surface of the support member 42c1 and the upper surface of the support member 42c2. One end of the guide rail 42a is closed by a support member 42c1, and the movement of the slider 42b in the X1 direction is restricted by the support member 42c1. The other end of the guide rail 42a is closed by a support member 42c2, and the movement of the slider 42b in the X2 direction is restricted by the support member 42c2.
The frame portion 42d is held by the pressing mechanism 43, and the pressing mechanism 43 causes the slide mechanism 42 to reciprocate in the Y direction shown in the figure.

Further, an air cylinder 42e for returning the nip is attached to one end side (support member 42c2 side) of the frame portion 42d. The air cylinder 42e urges the slider 42b, which has moved to the support member 42c2 side, to the support member 42c1 side (the peeling member 31 side) in response to an instruction from the control unit 60 (in response to a control signal). Then, the slider 42b urged by the air cylinder 42e moves in the X1 direction along the guide rail 42a, stops in contact with the support member 42c1. Accordingly, the nip plate 41 held by the slider 42b is disposed at a home position (a position of the nip plate 41 shown in FIG. 8A) described later.

Further, the slurder 42b holds the nip plate 41 via a holding fitting made of an L-shaped fitting or the like. Specifically, the slider 42b of the first moving mechanism 40A supports the upper end of the nip plate 41, and the slider 42b of the second moving mechanism 40B supports the lower end of the nip plate 41. Thereby, when the slider 42b moves along the guide rail 42a in the length direction (X direction shown in the figure) of the second transport belt 21, the nip plate 41 moves together with the moving slide 42b.

The pressing mechanism 43 includes a holding member 43 a that holds the frame portion 42 d of the slide mechanism 42, and is configured so that the holding member 43 a moves in the “Y direction illustrated” in response to a control signal from the control unit 60. Has been. In the example shown in the figure, the reference numeral 43b is an electromagnet. By supplying electric power to the electromagnet 43b, the holding member 43a is pulled by a magnetic force and operates in the “Y1 direction shown in the figure”. When the supply is stopped, the holding member 43a returns to the “Y2 direction shown”. In the present embodiment, the holding member 43a is urged in the “Y2 direction shown” by a biasing means (not shown) such as a spring when no magnetic force is generated. With this configuration, the nip plate 41 supported by the slide mechanism 42 held by the holding member 43a moves in the “Y1 direction shown” when electric power is supplied to the electromagnet 43b. Further, when the supply of power to the electromagnet 43b is stopped, the nip plate 41 moves in the “Y2 direction shown”.

Next, the operation of the label sticking apparatus of this embodiment will be described with reference to FIGS.
8 and 9 are schematic diagrams for explaining the label transfer operation from the first conveying belt to the second conveying belt of the label sticking apparatus of the present embodiment. FIG. 10 is a schematic diagram for explaining a label sticking operation by the label sticking apparatus of the present embodiment, and is a schematic diagram showing a state where a label is stuck on the adherend.

First, the user sets the labeling device to the initial operating 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 temporarily bonds the back surface (adhesive layer 4) of the strip-shaped label body 8 to the first transport belt 11. Then, the user operates the operation unit 70 to drive the first transport belt 11 and move the belt-like label body 8 to a predetermined position of the first transport belt 11 (in an initial operation state), thereby performing the first transport. The driving of the belt 11 is stopped. In addition, as shown in FIG. 8A, 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 first transport belt 11 has reached the peeling portion 32 of the peeling member 31. State. Further, in the initial operation state, the nip plate 41 of the label moving mechanism 40 has one end (tip) stopped at the position of one end (tip) of the peeling member 31 as shown in FIG. (The position of the nip plate 41 is referred to as “home position”). The nip plate 41 is disposed away from the first transport belt 11 and does not come into contact with the first transport belt 11 when moving.

Note that the setting of the initial operation state may be performed, for example, by the control unit 60 controlling the first belt 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 first conveying belt 11 reaches the peeling portion 32 of the peeling member 31. ) To send. Then, the setting of the initial operation state by the control unit 60 is performed as follows.

Specifically, the user pulls out the strip-shaped label body 8 from the label roll L attached to the roll support portion 9, temporarily attaches the back surface (adhesive layer 4) of the strip-shaped label body 8 to the first transport belt 11, and performs control. An initial operation state setting command is input to the unit 60. When the control unit 60 receives the initial operation state setting command, the control unit 60 starts to move the first conveyor belt 11, and upon receiving an initial state detection signal from the sensor, stops the operation of the moving first conveyor belt 11. Let Thereby, a label sticking apparatus is set to an initial operation state.

Then, when the label sticking device is set to the initial operation state, the user then operates the operation unit 70 to input a driving request. When the operation request is input, the control unit 60 transmits a control signal (operation instruction signal) to the first belt mechanism 10 to cause the first conveyor belt 11 to operate intermittently, and to perform a predetermined time (first time (T1: for example, for example) , 0.1 second)), the first conveyor belt 11 is moved, and then the movement is stopped. Thereby, the strip-shaped label body 8 temporarily bonded to the first transport belt 11 moves along with the first transport belt 11 by a predetermined dimension (moves as shown in FIGS. 8A to 8C). . Due to the movement of the first conveying belt 11, the leading label 1a of the strip-shaped label body 8 temporarily bonded to the first conveying belt 11 becomes a circle of the peeling member 31 as shown in FIGS. It collides with the slidable contact portion 32 having an arcuate shape and peels off from the first conveyor belt 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 “arc-shaped sliding contact portion 32”. As a result, as shown in FIG. 8C, the leading label 1a peeled off from the first conveying belt 11 is bent in an arc shape along the sliding contact portion 32, and its tip portion is inverted, and the inversion is performed. The adhesive layer 4 at the tip end is in contact with the second 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 60 moves the first conveyor belt 11 for a predetermined time (first time). However, the movement amount of the first conveyor belt 11 is determined according to the predetermined time. In other words, a sensor (not shown) is made to detect that the leading end portion of the leading label 1a has reached the predetermined position of the second conveying belt 21 (the state shown in FIG. 8C is detected). ), The first conveyor belt 11 may be stopped by a detection signal from the sensor.

Next, when the first transport belt 11 is stopped, the control unit 60 transmits a control signal (drive command) to the moving mechanism 40 and is peeled off from the first transport belt 11 by the nip plate 41 and reversed. The front end portion of 1a is pressed against the second conveyor belt 21. In the present embodiment, the electromagnet 43b of the label moving mechanism 40 is turned on (power is supplied to the electromagnet), and the entire slide mechanism 42 holding the nip plate 41 is urged in the Y1 direction shown in the figure by the magnetic force. To do. As a result, as shown in FIG. 8C, the leading end portion of the leading label 1a is sandwiched between the nip plate 41 and the second conveying belt 21 (the adhesive layer 4 at the leading end portion of the leading label 1a is second conveyed). Pressed against the belt 21).

Next, the control unit 60 transmits a control signal (operation instruction signal) to the second belt mechanism 20 while holding the leading end portion of the leading label 1a between the nip plate 41 and the second conveying belt 21. 2 The conveyor belt 21 is moved for a predetermined time (second time (T2)). Accordingly, the nip plate 41 moves from the position shown in FIG. 8C to the position shown in FIG. 9A as the second transport belt 21 moves. By this operation, the leading label 1a of the strip-shaped label body 8 temporarily bonded to the first transport belt 11 is pulled in the X1 direction by the nip plate 41 and the second transport belt 21. In addition, the rear end portion of the leading label 1a temporarily bonded to the first transport belt 11 is slipped along the “sliding contact portion 32 that is recessed in an arcuate shape”, like the front end portion of the label 1a. Extruded, reversed, and temporarily bonded to the second conveyor belt 21.

As described above, in the present embodiment, the leading end portion of the leading label 1a is peeled off from the first conveying belt 11 and bent in an arc shape along the sliding contact portion 32, and the leading end portion is inverted and the second conveying belt 21 is reversed. Then, the second conveyance belt 21 is moved in the X1 direction while pressing the reversed portion with the second conveyance belt 11 by the nip plate 41. For this reason, the rear end portion of the leading label 1a temporarily bonded to the first transport belt 11 also moves along the adhesive layer 4 along the “sliding contact portion 32 that is recessed in an arc shape”, which is more reliable. In addition, the label 1 can be peeled off from the first conveyor belt 11 and transferred to the second conveyor belt 21.

Further, when the leading label 1a moves from the first conveying belt 11 to the second conveying belt 12 (when the state becomes as shown in FIG. 9A), the control unit 60 then sends a control signal (driving stop) to the moving mechanism 40. Command) to turn off the electromagnet 43b of the label moving mechanism 40 (stops the supply of power to the electromagnet). As a result, the nip plate 41 is urged toward the first conveyor belt 11 by the urging means (not shown) (biased in the Y2 direction) and moves toward the first conveyor belt 11 (see FIG. 9B). State). Thereafter, the control unit 60 transmits an air cylinder driving signal (control signal) to the label moving mechanism 40, operates the air cylinder 42e, and biases the slider 42b holding the nip plate 41 toward the peeling member 31 side. Then, the slider 42b is moved to the peeling member 31 side (moved along the guide rail 42a). Thereby, as shown in FIG.9 (c), the nip board 41 returns to a home position. 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 control unit 60 holds (stores) the time for turning off the electromagnet 43b (third time (T3 (T3 <T2))) in advance and transmits a control signal (drive command) to the moving mechanism 40. After the third time (T3) has elapsed, it may be determined that the transfer of the leading label 1a has been completed, and the electromagnet 43b of the label moving mechanism 40 may be turned off and the air cylinder 42e may be operated. Alternatively, when the control unit 60 detects that the leading label 1a has been transferred to the second transport belt 21 by a sensor (not shown), the control unit 60 determines that the transfer of the leading label 1a has been completed, and the label moving mechanism 40 The electromagnet 43b may be turned off and the air cylinder 42e may be operated.

Next, when the nip plate 41 returns to the home position, the control unit 60 stops the second conveyor belt 21 and returns to the process of FIG. That is, the control unit 60 stops the second transport belt 21 when a second time (T2) has elapsed after transmitting a control signal (operation instruction signal) to the second belt mechanism 20. In the above description, when the control unit 60 transmits a control signal (operation instruction signal) to the second belt mechanism 20 and the second time (T2) has elapsed, the second conveyance belt 21 is stopped. However, 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 60 receives a detection signal from the sensor, the second conveyance belt 21 is stopped. You may do it.

By comprising in this way, the label 1 can be peeled off one by one from the belt-like label body 8 temporarily bonded to the first conveying belt 11 and reliably transferred to the second conveying belt 21 for transfer. . Then, the label 1 moved to the second transport belt 21 by the label moving mechanism 40 is temporarily bonded to the second transport belt 21 at a predetermined interval. In this state, the label 1 moves along with the second conveyor belt 21 toward the reversing shaft 25. The interval between the labels 1 that are temporarily bonded to the second conveyor belt 21 is matched with the interval between the adherends W that move on the belt conveyor 200.

Then, as shown in FIG. 10, the label 1 temporarily bonded to the second conveyance belt 21 moves together with the second conveyance belt 21, and moves from the label 1 that moves from the label 1 that moves at the top at the position of the second reversing shaft 25. The peeled label 1 is peeled off from the transport belt 21 and is pushed out from the second transport belt 21 and protrudes. In addition, the back surface (adhesive layer 4) of the label 1 protruding from the second conveyor belt 21 is adhered to the adherend W moving on the belt conveyor 200, and the adherend W moves in this state to move the adherend. The label 1 is affixed to the body W. At this time, since the label 1 is pushed out by the second conveyor belt 21 in addition to the pulling force from the adherend W moving on the belt conveyor 200, the label 1 from the second conveyor belt 21 is not peeled properly. Is prevented.

Further, in this embodiment, the traveling direction of the belt conveyor 200 and the traveling direction of the second transport belt 21 moving toward the second reversing shaft 25 are the same direction (a direction that is not the opposite direction). By comprising in this way, when attaching the label 1 to the to-be-adhered body W, it becomes unnecessary to reverse the direction of the front and back of the label 1, Therefore The label 1 can be affixed on the exact sticking position. Further, if the moving speed of the second conveyor belt 21 and the moving speed of the belt conveyor 200 are set to be the same speed, air can be prevented from entering between the adherend W and the label 1, Wrinkles are prevented from occurring on the label 1 to be attached.

As described above, in the present embodiment, the first conveyor belt 11 and the second conveyor belt 21 are configured by a plurality of belt-shaped belts, and the plurality of belt-shaped belts are arranged in parallel with a predetermined gap in the width direction. Is adopted. Then, the peeling member 31 formed with the slidable contact portion 32 recessed in an arc shape is formed on the gap portion formed on the label peeling surface 11A of the first conveying belt 11 and the label receiving surface 21A of the second conveying belt 21. It arrange | positions so that it may straddle the gap part made. That is, in this embodiment, since the peeling member 31 can be disposed in each gap portion (a plurality of gap portions formed) of the first conveyance belt 11 and the second conveyance belt 21, the first conveyance belt 11 can be more reliably provided. The leading end portion (leading label 1) of the strip-shaped label body 8 temporarily adhered to the first conveyor belt 11 can be peeled off and inverted. As a result, according to this embodiment, it is possible to provide a label sticking device that peels the label 1 from the strip-shaped label body 8 and attaches the label 1 to the adherend W with high accuracy.

In the present embodiment, when the label 1 is transferred from the first conveyance belt 11 to the second conveyance belt 21, the nip plate 41 adheres the leading end portion of the label 1 a peeled off from the first conveyance belt 11 and reversed. Since the surface 4 is urged and pressed toward the second conveyor belt 21, the label 1 can be temporarily adhered to the second conveyor belt 21 reliably. The leading label of the strip-shaped label body 8 temporarily bonded to the first conveyor belt 11 is moved by moving the second conveyor belt 21 while the label 1 is held between the nip plate 41 and the second conveyor belt 21. The method of Patent Document 2 described above (a method of transferring the label from the first conveyor belt to the second conveyor belt by simply bringing the adhesive surface of the leading label of the strip-shaped label body into contact with the second conveyor belt). The label 1 can be transferred from the first conveyor belt 11 to the second conveyor belt 21 with higher accuracy than the above.

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.

For example, in the above-described embodiment, the peeling member 31 is disposed in each gap portion (six gap portions) of the first conveyance belt 11 and the second conveyance belt 21, but the present invention is particularly limited to this. is not. For example, among the gaps (six gaps) between the first conveyor belt 11 and the second conveyor belt 21, only the gaps at the upper and lower ends and the third (or fourth) gap from the top. Alternatively, the peeling member 31 may be installed.

In the above-described embodiment, the first transport belt 11 is composed of seven belt belts 11a1, 11a2, 11a3, 11a4, 11a5, 11a6, and 11a7, and the second transport belt 21 is composed of the seven belt belts 21a1. 21a2, 21a3, 21a4, 21a5, 21a6, 21a7, the number of belt-like belts 11a1 to 11a7 (band-like belts 21a to 21a7) is appropriately set.

For example, in the above-described embodiment, the pressing mechanism 43 of the label moving mechanism 40 is moved in the Y direction shown in FIG. 2 Although pressed against the conveyor belt 21, it is not particularly limited to this. Any configuration other than the electromagnet 43b can be used as long as it can move the nip plate 42 held by the slide mechanism 42 in the Y direction and press the tip portion of the label 1 reversed by the peeling member 31 against the second transport belt 21. It may be.

In the above-described embodiment, the label 1 is conveyed by the first conveyance belt 11 provided in the first belt mechanism 10, but the present invention is not particularly limited to this. Instead of the first belt mechanism 10, for example, the label 1 may be transported to a desired position by a label transport mechanism including a rotating drum. As this rotating drum, a structure having a plurality of disc-shaped branching drums arranged in parallel to each other and a rotating shaft that supports the plurality of disc-shaped branching drums can be used. Then, the label 1 is temporarily adhered to the peripheral surface of the rotating drum (the peripheral surface of each disk-shaped branching drum), and the label 1 is conveyed by the rotation of the rotating drum.
In the above rotating drum, the disc-shaped branch drums arranged adjacent to each other are arranged so as to be separated from each other (the gap between the disc-shaped branch drums arranged adjacent to each other). Is formed). And the effect similar to embodiment mentioned above is acquired by arrange | positioning the peeling member 31 in the clearance gap between disk shaped branching drums. That is, one end in the width direction of the peeling member 31 is inserted into the gap between the disc-shaped branch drums arranged adjacent to each other, and the other end in the width direction of the peeling member 31 is the label of the second conveyor belt 21. It is inserted through a gap formed on the receiving surface 21A.

In addition, when the label 1 is a product advertising label (POP label) in which an adhesive portion that can be attached to the product and a non-adhesive portion that cannot be attached to the product are formed on the back surface of the label 1, the back surface of the label 1 The first conveyor belt 11 (and the second conveyor belt 21) disposed at a position that contacts the non-adhesive portion may be formed of an adhesive belt.
