DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film label connecting device for connecting a film label wound around a core and a new film label to an end portion of a previously drawn film label.

[0002]

2. Description of the Related Art Conventionally, it has been widely practiced to continuously supply a band-shaped roll label wound around a core to a labeler. Generally, this type of labeler is provided with a connecting device for a roll label, and this connecting device can connect the leading end of a new roll label to the end of the preceding roll label when the preceding roll label is consumed. It has become.

[0003]

However, when an extremely thin film label, such as polypropylene, is used as the roll label, the film label has a weak stiffness. There is a disadvantage that it is difficult to pull out the leading end of the film label, or even if the leading end can be pulled out, the leading end of the film label is curved and the next connecting operation becomes difficult. SUMMARY OF THE INVENTION In view of such circumstances, the present invention provides a film label and a connection device that can easily pull out the leading end of a film label and can perform a connection operation reliably.

[0004]

That is, the film label of the present invention is characterized in that a reinforcing piece for connection, which is stronger than the film label, is attached to the leading end of the film label wound around the core. Things. Further, the film label connection device of the present invention is a support table for rotatably supporting a film label wound on a core, and by rotating the film label wound on the core, the tip of the film label. Tip withdrawal means for withdrawing a connection reinforcing piece having a higher rigidity than the attached film label along a guide;
While holding the leading end or the connecting reinforcing piece of the film label pulled out by the leading end pulling means, the leading end or the connecting reinforcing piece of the film label held at the time of connection follows the film label that has been drawn out earlier. Holding means for applying an adhesive to the leading end of the film label or the reinforcing piece for connection held by the holding means, a film label previously drawn and And a press-contact means for pressing the leading end of the film label or the connecting reinforcing piece, which is advanced in advance, to adhere the two via the adhesive.

[0005]

According to the film label connecting device of the present invention,
If the film label supported by the support table is rotated, the leading end of the film label will be drawn out along the guide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiment. In FIG. 1, a film label connecting device 1 includes a rotary table 3 which is rotated about a rotary shaft 2 in a horizontal plane. The table 3 is provided with two support tables 4 and 5 at vertically symmetric positions about the rotation shaft 2. The rotary table 3 and the support tables 4, 5 are independently driven to rotate by servo motors (not shown). The support tables 4 and 5 are for supporting the film labels L (see FIG. 2) wound around the core 7, respectively, and support shafts 4a and 5a provided at the rotation centers of the support tables 4 and 5 respectively. By inserting the film label L into the core 7, the film label L can be rotatably supported in a horizontal plane. In the illustrated embodiment, the upper support table 4 in FIG.
Is the consumption position A, and this support table 4
The film label L is pulled out from the core 7 supported by the above and supplied to a labeler (not shown). On the other hand, the position of the lower support table 5 in FIG. 1 is a supply position B. At this supply position B, the old core 7 is removed, and the film label L wound around the new core 7 is attached. Is in a standby state.

At the position adjacent to each of the support tables 4, 5, there is provided a leading end drawing means 9, and the leading end drawing means 9 is adapted to remove the leading end of the new film label L supplied to each supporting table 4, 5. The film label L can be pulled out with the width direction thereof oriented vertically. Further, at a position on the right side of the leading end drawing means 9 on the supply position B side, a holding means 1 for holding the leading end of the film label L drawn by the leading drawing means 9.
0, and the adhesive applying means 11
The adhesive is applied to the leading end of the film label L held at 0. And film label L
When the adhesive is applied to the leading end of the film label, when the new and old film labels are connected, the holding means 10 follows the preceding film label L drawn from the consumption position A and advances the held film label. It has become. At the same time, the pressing means 12 is integrated with the holding means 10.
And the cutter 13 are also advanced, and the pressing means 12 presses the old film label L, which has been drawn in advance, and the leading end of the new film label, which is advanced following it, in the predetermined connection area C, so that both are pressed. And the cutter 13 cuts the trailing portion of the old film label L adjacent to the connection point.
And after this, the turntable 3 is rotated 180 degrees,
The support table 5 located at the supply position B becomes the consumption position A
At the same time, the support table 4 located at the consumption position A is moved to the supply position B.
Then, the film label L wound around the new core 7 is attached to the support table 4 and enters a standby state.

However, since the film label L is extremely thin and its stiffness is weak, there is a disadvantage that the film label L falls down even if the width direction of the film label L is kept vertical. Therefore, in this embodiment, as shown in FIG.
At the leading end of the film label L, a connection reinforcing piece 15 that is stronger than the film label is attached. That is, the film label L of the present embodiment is made of, for example, an extremely thin polypropylene film wound around a paper core 7.
A strong reinforcing piece 15 made of a paper piece having the same width as that of the film label L is attached to the leading end of the film label L.
Although the polypropylene film can be made extremely thin, it has a very low stiffness, which makes it difficult to pull out the front end portion L1 of the film label L by the front end drawing means 9, and even if the film label L can be drawn out. There is a disadvantage that the distal end portion L1 is curved and the subsequent connection work becomes difficult. The reinforcing piece 15 is provided in order to solve such a defect. In the illustrated embodiment, the reinforcing piece 15 has a state in which the end portion is slightly overlapped with the leading end L1 of the film label L or has a protrusion. An auxiliary tape 16 for reinforcement is adhered to the portion in a state where it is adhered. A temporary fixing adhesive tape 17 as an adhesive is adhered to a substantially central portion inside the reinforcing piece 15. This adhesive tape 17 has a strong adhesive force on the reinforcing piece 15 side and a weak adhesive force on the opposite surface side, so that when the adhesive reinforcing piece 15 is wound on the film label L, the adhesive strength is reduced. The piece 15 is adhered onto the film label L with the adhesive tape 17 so that the film label L wound around the core 7 cannot be unwound naturally. When the adhesive reinforcing piece 15 is pulled out, the adhesive tape 17 remains on the adhesive reinforcing piece 15 side. Further, register marks 18 are provided on the film label L at predetermined intervals in the longitudinal direction.

Since each of the leading end pull-out means 9 has the same structure, the support table 5 located at the supply position B is provided.
A description will be given of the structure of the tip drawing means 9 on the side. As shown in FIG. 3, the tip drawing means 9 has a substantially arc-shaped fixed guide 20 provided at a position near the outer peripheral portion of the support table 5 at the supply position B. A movable roller 23 having a drive roller 21 rotatably provided at a predetermined position on the fixed guide 20 and a small-diameter guide roller 22 in contact with the drive roller 21.
And As described above, the film label L is supported on the support table 5 at the supply position B, and the support table 5 can be rotated clockwise by a motor (not shown). As a result, the leading end portion L1 of the film label L slides and is guided along the inner peripheral surface of the fixed guide 20, and then is inserted into the gap between the driving roller 21 and the leading end portion of the movable guide 23. I have. As shown in FIG. 4, the fixed guide 20 is horizontally mounted on the upper end of a support shaft 25 erected on the turntable 3 (see FIG. 1). Guide surface 20 of fixed guide 20
“a” is arranged along the outer peripheral portion of the support table 5 over a substantially quarter area of the outer peripheral portion of the support table 5, and further extends linearly to the right side. In this embodiment, the fixed guide 20 is formed by arranging a plurality of thin plate members at equal intervals in the vertical direction and connecting the plurality of thin plate members with a plurality of connection bolts. The drive roller 21 is rotatably provided at a position where the guide surface 20a of the fixed guide 20 changes from a substantially arc shape to a straight shape. The outer peripheral surface of the drive roller 21 projects slightly toward the support table 5 from the guide surface 20 a of the fixed guide 20. The driving roller 21 is linked to a motor 26 provided at the lower end thereof.
Is rotated counterclockwise when the motor 26 is operated.

Next, the movable guide 23 is arranged along a region where the guide surface 20a of the fixed guide 20 is linear and close to the guide surface 20a. FIG.
As shown in FIG. 2, the movable guide 23 is also formed by connecting a plurality of plate-like members with bolts, similarly to the fixed guide 20. Then, a portion facing the linear region of the guide surface 20a of the fixed guide 20 is defined by the guide surface 23a of the movable guide 23.
And The movable guide 23 can be moved up and down through an elevating mechanism (not shown) to an upper position at the same height as the fixed guide 20 and a lower position shown in FIG. 4 below the same. 3 and 4, and can be translated along the fixed guide 20 between a forward position indicated by a solid line and a retracted position retracted to the right by a predetermined amount from the advanced position.

As shown in FIG. 3, a left end 23b of the movable guide 23 is sharpened in a V-shape, and a guide roller 22 is rotatably provided adjacent to the end 23b. And the movable guide 23 is fixed guide 2
When it is supported at an upper position having the same height as 0 and is at the forward position, a V-shaped gap in which the left side is expanded by the guide surface 23a of the distal end portion 23b of the movable guide 23 and the guide surface 20a of the fixed guide 20 is provided. 27 are formed. Further, at this time, the guide roller 22 at a position adjacent to the gap is in pressure contact with the drive roller 21, and at a position on the right side of these contact portions, the guide surface 20a of the fixed guide 20 and the guide surface 23a of the movable guide 23 Are maintained at a distance slightly larger than the thickness of the film label L. When the support table 5 is rotated clockwise and the drive roller 21 is rotated counterclockwise from this state, the reinforcing piece 15 connected to the leading end L1 of the film label L supported by the support table 5 becomes
The fixed guide 20 slides on the guide surface 20a to be guided in the clockwise direction, and is eventually inserted into the gap 27. Thereafter, the reinforcing piece 15 of the film label L is sandwiched between the driving roller 21 and the guide roller by the rotation of the driving roller 21 and is drawn out to the right side.

Also, as shown in FIG.
An air nozzle 28 for ejecting air is provided at a position adjacent to the air nozzle 28. When the tip of the reinforcing piece 15 of the film label L is pulled out by the tip pulling means 9, the air nozzle 28 is used.
The air is blown out toward the gap 27 on the left side. Thereby, the guide surface 20a of the fixed guide 20
When the reinforcing piece 15 connected to the film label L moves toward the gap 27 along the line, the tip of the reinforcing piece 15 is opened outwardly, whereby the reinforcing piece 15 Is inserted into the gap 27.

As shown in FIGS. 3 and 4, a sensor 30 is provided at a predetermined position of the movable guide 23 so as to be orthogonal to the guide surface 23a. Contact the drive roller 21
The rotation of the reinforcing piece 15 causes the two guide surfaces 21a, 23a
The sensor 30 detects the register mark 18 (see FIG. 2) attached to the film label L when it is pulled out to the right side between. A signal detected by the sensor 30 is input to control means (not shown), and the control means operates a conventionally known cutter 31 according to the detection signal. The cutter 31 is provided on an extension of the right end of the fixed guide 20, and the reinforcing piece 15 drawn to the right side of the right end of the fixed guide 20 is shown in FIG. 2. The reinforcing piece 15 is cut at a cutting position E, that is, at a position slightly behind the adhesive tape 17 adhered to the reinforcing piece 15.

In the tip pulling means 9 having the above-described structure, the movable guide 23 is first positioned at the upper position. From this state, the support table 5 is rotated clockwise and the drive roller 21 is rotated counterclockwise.
At the same time, the air nozzle 28 is operated, and the movable guide 23 is further advanced to the forward position. Thereby, the guide roller 22 of the rotation guide 23 is pressed against the drive roller 21, and a gap 27 is formed between the guide surface 20 a of the fixed guide 20 and the guide surface 23 b of the movable guide 23.
Thereafter, as the support table 5 is rotated clockwise, the reinforcing pieces 15 connected to the film label L are guided by the guide surface 20a of the fixed guide 20, and then the gap 27 is formed.
Is inserted into. At this time, the reinforcing piece 15 is
, The tip of the reinforcing piece 15 is pressed outward and is reliably inserted into the gap 27. If the reinforcing piece 15 is not provided, the leading end of the film label L warps rearward in the transport direction due to the air blown from the air nozzle 28, so that it is difficult to insert the leading end into the gap 27. Becomes On the other hand, when the air blowing of the air nozzle is stopped in order to prevent the warping of the above-described tip, the tip of the film label L is in close contact with the film label on the inner peripheral side. 20
It is difficult to insert the gap 27 along the guide surface 20a. Thus, the reinforcing piece 15 is attached to the film label L.
Is provided, the leading end of the film label L can be pulled out.

Next, the reinforcing piece 1 inserted into the gap 27
5 is the guide surface 2 of the fixed guide 20 after being sandwiched between the rotating drive roller 21 and the guide roller 22.
0a and the guide surface 23a of the movable guide 23. At this time, the adhesive tape 17 that has adhered the reinforcing piece 15 to the film label L wound around the core 7 is peeled off from the film label L side and remains adhered to the reinforcing piece 15 side. Then, when the first register mark 18 attached to the film label L is detected by the sensor 30, the rotation of the drive roller 21 and the support table 5 is stopped, and the drawing of the film label L is stopped. At this time, the reinforcing piece 15 has reached the position of the cutter 31, and the cutter 31 cuts the reinforcing piece 15 at a predetermined cutting position E. At this time, since a part of the reinforcing piece 15 is left at the front end of the film label L, the remaining reinforcing piece 15 is stably maintained in that state. Also,
The movable guide 23 is retracted to the retracted position, whereby the guide roller 22 and the drive roller 21 of the movable guide 23 are separated from each other, so that the film label L can be freely pulled out without receiving the resistance between the guide roller 22 and the drive roller 21. It becomes possible.

Next, the reinforcing piece 1 of the new film label L pulled out from the supply position B by the tip pulling-out means 9 is described.
Next, a configuration for connecting the old film label L drawn out from the consumption position A and consumed now will be described. As shown in FIGS. 1, 5 and 6, the distal end portion of the distal end drawing means 9 is provided with a pair of guide rails 33 and 34 extending in parallel to the right from the distal end portion. , 34 are mounted on the frame 35 in a horizontal state.

, A ball screw 42 is rotatably supported in parallel to the adjacent position. This ball screw 42 is
Threaded through. The above ball screw 42
Are linked to a motor 44 via a timing belt 43. The operation of the motor 44 is controlled by control means (not shown).
By rotating in the forward and reverse directions, the holding means 10 can be reciprocated along the guide rail 34.

Next, the holding means 10 for sucking and holding the reinforcing piece 15 of the film label L will be described. The holding means 10 is provided with a suction surface 10a for sucking and holding the reinforcing piece 15 of the film label L, and the suction surface 10a is located at a position close to the currently consumed film label L. On the other hand, a flat pressure contact surface 12a is provided on the pressure contact means 12 at a position facing the holding means 10 with the film label L interposed therebetween. Suction surface 1 of holding means 10
At 0a, a plurality of holes for inhaling the atmosphere are opened,
These holes communicate with a negative pressure source (not shown) via a negative pressure passage provided in the holding means 10. The operation of the negative pressure source is also controlled by control means (not shown). Suction surface 10a
Is brought close to the film label L, and a negative pressure is applied from the negative pressure source to the negative pressure passage, the film label L can be sucked and held by the suction surface 10a. When the supply of the negative pressure is stopped, the suction state of the film label L by the suction surface 10a is released. The suction surface 10a is supported by the tip of an air cylinder 45, and the operation of the air cylinder 45 is controlled by control means (not shown). In the non-operation state of the air cylinder 45, as shown in FIG. 5, the suction surface 10a is separated by a predetermined distance from the pressure contact surface 12a of the pressure contact means 12 which is the opposing position, and the current position of the close front surface position of the pressure contact surface 12a. It is also separated from the consumed film label L. On the other hand, the air cylinder 4 is controlled by the control means.
5, the suction surface 10a comes into contact with the film label L and presses it against the pressing surface 12a of the pressing means 12.
It is designed to be advanced to the position where it is pressed against.

Further, the cutter 3 of the tip withdrawing means 9 is used.
Adhesive applying means 11 for attaching a double-sided tape as an adhesive to one surface of the reinforcing piece 15 of the film label L is provided adjacent to the position 1 (see FIG. 5). The adhesive applying unit 11 is rotated by 90 degrees so that the double-sided tape cut to a predetermined length can be attached to the film label L. The holding means 10 whose operation is controlled by the control means is first moved to the position of the cutter 31 of the tip pull-out means 9 to suck and hold the reinforcing piece 15 of the new film label L on the suction surface 10a. After moving to the adhesive applying means 11 and temporarily stopping it, the control means operates the air cylinder 45 in this state to advance the suction surface 10a. Thereby, the adhesive applying means 11 is attached to one surface of the reinforcing piece 15 of the film label L.
Then, the operation of the air cylinder 45 is stopped, so that the reinforcing piece 15 to which the double-sided tape is attached is attached.
Is separated from the adhesive applying means 11. Note that the film label L and the reinforcing piece 15 may be bonded by hot melt instead of the double-sided tape.

According to the configuration described above, first, the holding means 1
0 is moved by the control means to the left end position shown by the imaginary line in FIG. Thereby, the suction surface 1 of the holding means 10
0a stops in front of the reinforcing piece 15 where the cutter 31 is located. In this state, a negative pressure is applied to the suction surface 10a from the negative pressure source via the negative pressure passage, and the reinforcing piece 15 is suction-held on the suction surface 10a. Thereafter, the holding means 10 moves rightward and stops in front of the adhesive applying means 11. Then, the air cylinder 45 is operated by the control means, and the reinforcing piece 15 held on the suction surface 10a is removed by the adhesive applying means 11.
The double-sided tape is adhered to one surface of the reinforcing piece 15, that is, the surface facing the currently consumed film label L. Thereafter, the operation of the air cylinder 45 is stopped, and the suction surface 10a holding the reinforcing piece 15 retreats. Further, the holding means 10 is moved rightward, stops in front of the pressure contact means 12, and enters a standby state. From this standby state, when it is detected by the sensor (not shown) provided at the consumption position A that the film label L of the consumption position A is almost consumed, the holding means 10 and the press-contact means 12 are moved to the label at the consumption position A. Is moved to the right side at the same speed as the consumption speed, and the air cylinder 45 is operated in this state to advance the suction surface 10a. As a result, the reinforcing piece 15 held on the suction face 10a is pressed against the currently consumed film label L located between the reinforcing piece 15 and the pressing face 12a of the pressing means 12. As a result, a new film label L is connected to the currently consumed film label L by the double-sided tape. When the connection of the reinforcing piece 15 of the new film label L to the currently consumed film label L is completed, the pressing means 12
The rear end is cut off from the connection point of the currently consumed film label L by the cutter 13 which is integrally provided with the cutter 13 and is moving in synchronization. Is drawn out. Thereafter, when the movable guide 23 is lowered, the rotary table 3 is rotated counterclockwise by 180 degrees, and the support table 5 and the film label L supported thereby are positioned at the consumption position A. Is located at the supply position B, and the next new film label L is set on the support table 4 located at the supply position B.

In the above embodiment, the reinforcing piece 15 is cut by the cutter 31 so that a part of the reinforcing piece 15 is left. However, holding means by a negative pressure or a claw is provided closer to the fixed guide 20 than the cutter 31. If the holding means can hold the leading end of the film label, the reinforcing piece 15 need not always be left. When the old film label and the new film label are directly connected, not only the double-sided tape but also a hot melt or a solvent may be used.
