Description of the Related Art Japanese Patent Application Laid-Open No. 8-165040 is known as a supply device for supplying a roll made of a cylindrical member and a band-shaped material wound therearound to a predetermined position. The apparatus disclosed in the above publication includes a transfer plate movable in a vertical direction and a horizontal direction, and supplies the strip-shaped material to the table as follows. That is, first, the transfer plate is supported in the vertical direction and is translated in parallel to the position of the end of the conveyor, and in this state, a pair of support members provided on the transfer plate are raised, thereby forming the forefront band on the conveyor. The material is supported at a predetermined height. After this, after translating the entire transfer plate to the position near the table,
Fold down the transfer plate and the band material supported by it until it is horizontal. Thus, the centering member on the table side is inserted into the cylindrical member of the roll body, and the transfer plate and the band-shaped material are horizontally supported above and near the table.
Thereafter, the entire transfer plate is moved in the horizontal direction and pulled out from between the table and the band-shaped material. Thereby, the roll body is supplied in a horizontal state on the table.

[0003]

By the way, as described above, in the conventional apparatus, at the end of the supply step of the roll body, the transfer plate is pulled out from between the strip material and the table. The transfer plate and the belt-shaped material in the roll body slide. Therefore, in the conventional apparatus, it has been pointed out that the belt-shaped material in the roll body is easily damaged.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present invention provides a stocker that supports a cylindrical member and a plurality of rolls made of a band-shaped material wound thereon so that an axis thereof is horizontal, and a roll that is provided so as to be movable in a horizontal direction and a vertical direction.

In a state where compressed air is not acting on the engagement pin 29 from the compressed air supply source, each engagement pin 29 is positioned at the inner end in each guide groove 21a by each spring. On the other hand, when compressed air acts on each engagement pin 29 from a compressed air supply source (not shown) through the air passage 30, the engagement pin 29 in each guide groove 21a is formed.
Are synchronously moved outward in the radial direction. As shown in FIG. 4, if compressed air acts on each of the engagement pins 29 from a state where the three engagement pins 29 are inserted into the cylindrical member 6 of the roll body 2, each of the three engagement pins 29 29
Is pressed against the inner peripheral portion of the cylindrical member 6, so that the roll body 2 can be held on the rotating body 13 by these three engagement pins 29. If the supply of compressed air to each engagement pin 29 is stopped from this state, the three engagement pins 2
Since 9 is returned to the original inward position by the spring, 3
The three engagement pins 2 are separated from the inner peripheral portion of the cylindrical member 6, whereby the holding state of the roll body 2 by the three engagement pins 2 is released. The above description is for the rotary plate 13 located at the supply position B on the lower side in FIG. 4, but the rotary plate 12 located at the other consumption position A has the same configuration as the rotary plate 13. The description of the configuration on the other rotating plate 12 side is omitted. That is, in the present embodiment, the pair of rotating plates 12 and 13 having the same configuration
The rolls 2 are provided at positions shifted from each other by 180 degrees, and the roll 2 supported on one of them is positioned at the consumption position A, and the other roll at the supply position B holds a new roll 2. I have. After the connection of the new and old labels R is completed by the connecting device 5, the roll 2 that has almost consumed the label R is supported on the rotary plate 12 located at the consumption position A. By stopping the supply of the compressed air to each of the engagement pins 29, the holding state of the cylindrical member 6 of the roll body 2 by each of the engagement pins 29 is released. Then, after this, the rotating plate 12 located at the consumption position A is moved in the vertical direction from the horizontal state, so that the roll body 2 substantially consisting only of the cylindrical member 6 falls off the rotating plate 12, and It is configured to be discharged into a collection box (not shown) provided outside the rotating body 11.

A screw shaft 39 is rotatably supported in parallel between the guide rails 44 on the upper surface of the elevating frame 33 in parallel with the guide rails 44, and a nut member is attached to the horizontal portion 45 a of the movable frame 45. 46 is screwed through. Screw shaft 39
Is rotated in the forward and reverse directions in conjunction with a motor (not shown) provided on the lifting frame 33. Then, as the motor interlocked with the screw shaft 39 is rotated in the forward and reverse directions, the movable frame 45 moves forward in the leftward position shown by the solid line in FIG. It is moved along the longitudinal direction of the stocker 31 between the end positions.

An air cylinder 47 is attached to the lower horizontal portion 45a of the movable frame 45 so as to face vertically upward. A holding member 48 having an arc-shaped upper surface is connected to the air cylinder 47. . On the other hand, an air cylinder 51 is attached to the upper horizontal portion 45b so as to extend vertically downward, and a lower end portion of the air cylinder 51 is connected to a holding member 52 having an arcuate lower surface. The holding members 48 and 52 are opposed to each other, and as can be understood from FIGS.

In addition, the frontmost roll 2 can be detected in response to the cylindrical member 6 of the roll 2. When the movement of the movable frame 45 is stopped after the sensor 53 detects the cylindrical member 6 of the roll 2, the holding members 48 and 52 stop at the vertical position of the roll 2 at the forefront position. I have.

Further, in this embodiment, the movable frame 45
Is provided with a sensor 54 for detecting the amount of advance of the air cylinder 47, that is, the amount of rise of the holding member 48. In the present embodiment, the delivery mechanism 32 is constituted by the movable frame 45, the holding members 48 and 52 provided on the movable frame 45, the sensors 53 and 54, and the like. The roll supply device 3 includes a delivery mechanism 32, a stocker 31, and the rotating plate 13 at the supply position B.

(Delivery Operation) The supply operation of the roll 2 by the roll supply device 3 configured as described above will be described. That is, first, the consumption position A is set by the connection device 5 described later.
End of the old label R of the roll body 2 of FIG.
After the end of the label R of the new roll body 2 that has been waiting at step S11 is connected, the rotating body 11 is rotated counterclockwise, so that the connected roll body 2 is located at the consumption position A. The rotating plate 13 in the empty state is in the supply position B.
To stop. Thereafter, since the motor interlocked with the swing member 23 shown in FIG.
3 is moved to the vertical direction as shown in FIG. As a result, the rotating plate 13 faces the roll body 2 at the foremost position supported by the stocker 31. At this time, the three engagement pins 29 on the rotating plate 13 are horizontally supported. At this time, the engagement pin 2
Since no compressed air acts on 9, the three engagement pins 29 are located on the inner side near the center of the rotating plate 13. On the other hand, the movable frame 45 of the delivery mechanism 32 is on standby at the forward end position indicated by the solid line in FIG. 6, and the air cylinders 47 and 51 provided on the movable frame 45 are not operated. As described above, the rotating plate 1 of B at the supply position
3 is supported in the vertical direction, the screw shaft 3 of the delivery mechanism 32
9 is rotated in reverse, so that the movable frame 4
5 retreats along the rail 44 from the forward end position to the retracted end position indicated by the imaginary line. When the sensor 53 provided on the movable frame 45 detects the cylindrical member 6 of the foremost roll body 2 of the stocker 31 in the process of moving the movable frame 45 backward, the reverse rotation of the screw shaft 39 stops. Is done. Thereby, the holding members 48 and 52 are located at the upper and lower positions of the roll body 2 at the forefront position.

Thereafter, first, the upper air cylinder 51
Is actuated, the holding member 52 is lowered and comes into pressure contact with the upper end of the label R of the roll body 2 at the foremost position. next,
Since the lower air cylinder 47 is operated, the lower holding member 48 is pressed against the lower end of the label R of the roll body 2 at the forefront position (see FIG. 5). Thus, the label R of the roll body 2 is held by the holding members 52 and 47 at the upper and lower positions. Here, in the present embodiment, the lower air cylinder 47 is larger than the upper air cylinder 51. Therefore, when the air cylinder 47 is raised, the air cylinder 51 is moved to the retreat end. As a result, the roll body 2 is lifted from the stocker 31 while being held by the holding members 52 and 47 at the upper and lower positions, and is supported at a predetermined height. That is, the roll body 2 at the forefront position is taken out of the stocker 31 by both the holding members 48 and 52.

In this state, the height of the cylindrical member 6 in the roll body 2 sandwiched between the sandwiching members 48 and 52 does not match the height of the engaging pin 29 on the side of the rotating plate 13 supported in the vertical direction. Therefore, even if the movable frame 45 is moved again to the forward end position in this state, the three engaging pins 2
9 will not be inserted into the inside of the cylindrical member 6 in the roll body 2. Therefore, in this embodiment, the advance amount of the lower air cylinder 47 is detected by the sensor 54, whereby the lifting frame of the cylindrical member 6 in the roll body 2 sandwiched between the sandwiching members 48, 52. 33, the height of the cylindrical member 6 and the rotating plate 1
The amount of deviation from the engagement pin 29 on the third side is calculated. Then, by rotating the motor 41 in the normal / reverse direction by the required amount, the lifting frame 33 is moved by the calculated deviation amount.
Raise and lower the whole. Thereby, both holding members 48, 52
Height of the cylindrical member 6 in the roll body 2 sandwiched between
It coincides with the height of the engaging pin 29 on the side of the rotating plate 13 supported in the vertical direction. Thereafter, since the motor linked to the screw shaft 39 is rotated forward, the movable frame 45 is stopped after being moved to the forward end position shown by the solid line. Thus, the roll body 2 sandwiched between the sandwiching members 48 and 52 comes into contact with the rotating plate 13 facing the same, and the 3
Two engagement pins 29 are inserted inside the cylindrical member 6 of the roll body 2.

Then, compressed air is applied to each of the engagement pins 29 of the rotating plate 13, so that each of the engagement pins 29 is synchronously moved outward and pressed against the inner peripheral portion of the cylindrical member 6. . Thereby, the three engagement pins 29 as the holding means are provided.
Thus, the roll body 2 is held.

Thereafter, the operations of the air cylinders 47 and 51 on the movable frame 45 side are stopped, so that the holding members 5
The rolls 2 and 47 return to the retracted position, and the roll body 2 is released from both the holding members 52 and 47. Thereafter, the rotating plate 13 holding the roll body 2 is moved from the vertical state shown in FIG.
It is rotated 0 degrees and returned to a horizontal state. In this embodiment, thereafter, the action of the compressed air on each engagement pin 29 is temporarily stopped, and the holding state of the cylindrical member 6 of the roll body 2 by each engagement pin 29 is released. As a result, the lower surface (one side of the label R) of the roll body 2 is reliably supported on the rotating plate 13, and thereafter, the compressed air is again applied to each of the engagement pins 29. The pin member 29 securely holds the cylindrical member 6 of the roll body 2. Thus, a new roll body 2 is supplied from the roll body supply device 3 to the rotating plate 13 at the supply position B. As described above, the roll body supply device 3 is configured to supply a new roll body 2 to the rotating plate 13 (12) supported at the supply position B in the vertical direction.

Reference) is detected. Further, on the extension of the right end of the fixed guide 71, a conventionally known cutter 7 is provided.
9 is provided so that the leading end R1 of the label R pulled out to the right side from the right end of the fixed guide 71 is supported by the cutter 79 so as to be cut. Further, the cutter 79 is provided with a tape sticking portion 122 for sticking a double-sided tape to one surface of the distal end portion R1.

Next, a mechanism for moving the movable guide 73 in the left-right direction on the drawing and a lifting mechanism will be described. As shown in FIG. 3, an elevating plate 83 is arranged above the rotating body 11, and the elevating plate 83 can be moved up and down by being guided by a guide shaft 84 erected on the rotating body 11. . Further, a screw shaft 85 is rotatably supported on the rotating body 11 in the vertical direction, and the screw shaft 85 is threaded through a nut member (not shown) provided on the elevating plate 83. The screw shaft 85 is linked to a motor 86 via a pulley provided at a lower end thereof and an endless belt. This motor 8
6 is rotated by a required amount in the normal and reverse directions, so that the lifting plate 8 is rotated.
The movable guide 73 provided at the position 3 can be raised and lowered to an upper position at the same height as the fixed guide 71 and the driving roller 72 and a lower position lower than the fixed guide 71 shown in FIG.

Further, a pair of guide rails 87 is provided on the upper surface of the elevating plate 83 so as to be parallel to the linear portion of the guide surface 71a of the fixed guide 71, and the bottom of the movable guide 73 is connected to these guides. It is movably mounted on a rail 87. Thereby, the movable guide 73 can move in the left-right direction along the linear portion of the guide surface 71a of the fixed guide 71, and as can be understood from FIG. When the guide surface 73a of the movable guide 73 and the linear portion of the guide surface 71a of the fixed guide 71 are close to each other, and the movable guide 73 is at the upper position, the guide surface 73a of the movable guide 73 and the fixed guide 71 Between the linear portion of the guide surface 71a,
A gap that allows the label R to be inserted substantially is maintained. The movable guide 73 mounted on the guide rail 87 as described above is connected to an air cylinder 88 provided on the elevating plate 83 (FIG. 7). The air cylinder 88 is at a retracted position in a non-operating state, and is advanced to an advanced end when activated. That is,
When the air cylinder 88 is not operated, the movable guide 73 is located at the retracted position, and when the air cylinder 88 is operated,
The movable guide 73 is advanced from the retreat position to the advance position shown in FIG. When the movable guide 73 is at an upper position at the same height as the fixed guide 71 and the movable guide 73 is in the forward position by operating the air cylinder 88, the guide roller 60 of the movable guide 73 moves around the outer periphery of the drive roller 72. The guide surface 7 of the movable guide 73 is pressed against the portion and is on the right side in FIG. 7 of the pressed portion.
A gap substantially equivalent to one label R is maintained between 3a and the linear portion of the guide surface 71a of the fixed guide 71.

(Explanation of Operation) The operation of the distal end pulling device 4 configured as described above will be described. First, the movable guide 73
At the same height as the fixed guide 71,
At the same time, the air cylinder 88 is kept in an inactive state. That is, at this time, the movable guide 73 is waiting at the retracted position, and the guide roller 60 is not pressed against the drive roller 72. On the other hand, the rotating plate 13 at the supply position B supports a new roll body 2. From this state, the rotating plate 13 is rotated clockwise and the drive roller 72 is rotated counterclockwise. At the same time, the air cylinder 88 is operated to move the movable guide 73 to the forward position. As a result, the guide roller 60 of the movable guide 73 is pressed against the drive roller 72, and the V-shaped gap 7 is formed between the guide surface 71 a of the fixed guide 71 and the distal end 73 b of the movable guide 73.
8 is maintained. Thereafter, as the rotating plate 13 is rotated clockwise, the leading end R1 of the label R is guided by the guide surface 71a of the fixed guide 71 and then inserted into the gap 78. At this time, since air is blown from the air nozzle 81 to the leading end portion R1 of the label R, the leading end portion R1 of the label R is turned outward and is reliably inserted into the V-shaped gap 78.

Since the driving roller 72 is being rotated, the leading end R1 of the label R is in contact with the driving roller 72 and the guide roller 60.
Between the fixed guide 71 and the guide surface 7
1a and the guide surface 73a of the movable guide 73, and is drawn out toward the right side between them. In the process of pulling out the leading end R1 of the label R in this manner, the first register mark attached to the label R
2, the rotation of the driving roller 72 and the rotating plate 13 is temporarily stopped, and the drawing of the label R is temporarily stopped, and the operation of the air cylinder 88 is also stopped. As a result, the movable guide 73 moves to the rear position shifted rightward by a predetermined amount from the front position indicated by the solid line. Therefore, the drive roller 72 and the guide roller 60 of the movable guide 73 are separated from each other, so that the label R located therebetween is released from the sandwiched state. for that reason,
The leading end portion R1 of the label R and its trailing portion are corrected by their own weights so that their longitudinal sides are substantially horizontal.

Thereafter, the air cylinder 88 is operated again to move the movable guide 73 to the forward position, so that the guide roller 60 of the movable guide 73 and the driving roller 72 again clamp the label R. That is, the label R is sandwiched between the movable guide 73 and the drive roller 72 in a state where the longitudinal side is substantially horizontal without meandering up and down, and from this state, the rotating plate 13 and the The drive roller 72 is rotated. As a result, the label R is further pulled out. When the sensor 82 further detects the second register mark R2 in this process, the rotation of the rotating plate 13 and the driving roller 72 is stopped. . At this time, the leading end R1 of the drawn label R reaches the position of the cutter 79 and is supported by the cutter 79, and the cutter 79 cuts the supported leading end R1. As a result, the cut portion becomes the leading end R1 of the new label R, and the length from the leading end R1 of the label R to the first register mark is made equal to the predetermined length. As a result, the leading end portion R1 of the label R and the succeeding portion are pulled out by the leading end pulling device 4 without meandering up and down and with the side portions being horizontal.

(Connecting Device) Next, the leading end portion R1 of the label R pulled out from the supply position B by the leading end drawing device 4
The connection device 5 that connects the label R that is currently drawn out from the consumption position A and consumed will be described. That is, as shown in FIG. 3, an elevating frame 91 is disposed on the fixed frame 14, and guide shafts 92 directed vertically downward are connected to a plurality of locations on the bottom surface of the elevating frame 91. These guide shafts 92 are slidably fitted to a cylindrical guide 93 erected on the fixed frame 14. A nut member 94 is provided at the center of the bottom of the lifting frame 91.
And the fixed frame 14 below the fixed frame 14
The upper part of the screw shaft 95 rotatably provided on the nut member 9

In other words, by rotating the handle 97 by the required amount in the normal and reverse directions, the lifting frame 91 and the entire connecting device 5 provided thereon can be raised and lowered by the required amount.

As shown in FIGS. 1, 3, 9 and 10, the connecting device 5 includes a pair of guide rails 101 and 102 extending from the upper side of the distal end drawing device 4 to the right side. The guide rails 101 and 102 are horizontally mounted on the elevating frame 91. The crimping unit 103 is movably attached to one of the guide rails 101, and the rotating body 1 is
The sliding block 104 is movably mounted at a position higher than 1. A rotatable engagement roller 105 is attached to the sliding block 104. The label R that has been drawn out and consumed from the consumption position A is hooked on the idle roller 106 on the rotating body 11 side, and then hooked on the engagement roller 105 of the sliding block 104, and then the two guide rails 10 are used.
1 and 102 are drawn out in parallel with them, and further, hooked on a plurality of idle rollers 107 provided at a position adjacent to the connection device 5 and then drawn out toward a labeler side (not shown). ing. An air cylinder 108 is provided at a position adjacent to the left end of the guide rail 101 (FIG. 9).
08 is connected to the sliding block 104. When the air cylinder 108 is not operated, the sliding block 104 is
9 is moved to the left side position shown by the solid line in FIG. 9 when the air cylinder 108 is operated when required. The operation of the air cylinder 108 is controlled by a control device (not shown). When the pressure bonding unit 103 is connected to a suction unit 111 to be described later, it moves from the position shown by the imaginary line on the right side of FIG. 9 to the position of the imaginary line on the left side. The slide block 104 is moved to the position indicated by the solid line in FIG. 9 by operating the slide block 104 so that the crimping unit 103 does not collide with the slide block 104.

On the other hand, a suction unit 111 is movably attached to the guide rail 102, and a ball screw 1 is provided in a position adjacent to the guide rail 102 in parallel with the guide unit.
12 is rotatably supported. This ball screw 112
Are screwed through the screw portion of the suction unit 111. The ball screw 112 is linked to a motor 114 via a timing belt 113. This motor 114
The operation of the suction unit 111 is controlled by a control device (not shown).
Can be reciprocated along.

(Structure of Suction Unit 111) The suction unit 111 has a suction surface 111a for sucking and holding the leading end portion R1 of the label R. The suction surface 111a is located at a position close to the currently consumed label R. It is located. On the other hand, a flat crimping surface 103a is provided on the crimping unit 103 side at a position facing the suction unit 111 with the label R interposed therebetween. The suction surface 111a of the suction unit 111 is provided with a plurality of holes for sucking the air, and these holes communicate with a negative pressure source (not shown) through a negative pressure passage provided in the suction unit 111. . The operation of the negative pressure source is also controlled by a control device (not shown). When the suction surface 111a is brought close to the label R and a negative pressure is applied from the negative pressure source to the negative pressure passage, the label R can be suctioned and held by the suction surface 111a. Suction surface 1 when the supply of negative pressure to
Thus, the state of adsorption of the label R by 11a is released. The suction surface 111a is supported by the tip of an air cylinder 115, and the operation of the air cylinder 115 is controlled by a control device (not shown). Then, when the air cylinder 115 is not operated, as shown in FIG.
11a is a crimping surface 1 of the crimping unit 103 which is an opposing position.
03a, and is also separated from the currently consumed label R at the front position near the crimping surface 103a. On the other hand, when the air cylinder 115 is actuated and advanced by the control device, the suction surface 111a comes into contact with the label R and urges the label R to the crimping surface 1 of the crimping unit 103.
It is designed to be advanced to a position where it is pressed against 03a.

The crimping unit 103 and the suction unit 111 are integrally connected by a connecting means 116 when necessary. That is, FIG.
As shown in FIG.
An engagement member 117 is swingably attached by a support shaft 118. This engaging member 117 is
The air cylinder 1 is provided on the back surface of the suction unit 111 rather than the support shaft 118.
21 are connected. The operation of the air cylinder 121 is also controlled by a control device (not shown). When the air cylinder 121 is not operated, the engagement member 117 is maintained in a horizontal state.
When the air cylinder 121 is actuated, the tip of the engaging member 117 on the suction unit 111 side is raised and inclined as indicated by the imaginary line. Engaging member 11
7, a square notch 117a is provided at the center of the tip of the suction unit 111 side.
On the upper part of 11, a linear engaging projection 111b is formed. Therefore, when the two units 103 and 111 are integrally connected, the control device operates the air cylinder 121 and the engaging member 117 is supported obliquely.
Suction unit 1 up to position facing crimping unit 103
11 is moved, and the control device stops the operation of the air cylinder 121 from that state. Then, the engaging member 117 is brought into a horizontal state by the weight of the engaging member 117, and the notch 117 a at the distal end thereof is engaged with the engaging protrusion 111 of the suction unit 111. Thereby, both units 103, 1
11 are integrally connected. When the air cylinder 121 is operated to separate the two units 103 and 111, the notch 117a of the engaging member 117 is
11 are disengaged from the engagement projections 111, whereby the connection between the two units 103, 111 is released. As described above, the connecting means 116 includes the engaging member 117, the air cylinder 121, and the engaging protrusion 111b.

Further, the connecting device 5 of this embodiment is provided with a label R at a position adjacent to the cutter 79 of the tip pulling device 4.
Is provided with a tape sticking portion 122 for sticking a double-sided tape to one surface of the tip end portion R1 (FIG. 9). This tape sticking part 1
Reference numeral 22 is rotated by 90 degrees so that the double-sided tape cut to a predetermined length can be supported toward the label R. The suction unit 111, the operation of which is controlled by the control device, is first moved to the position of the cutter 79 of the front-end drawing device 4 to suction-hold the front end R1 of the label R on the suction surface 111a. Move to the wearing part 122 and stop temporarily,
In this state, the control device operates the air cylinder 115 to move the suction surface 111a forward. As a result, one surface of the leading end portion R1 of the label R is bonded to the double-sided tape of the tape attaching portion 122, and then the operation of the air cylinder 115 is stopped.
Are separated from the tape attaching portion 122. In this manner, the control device is configured to move the suction unit 111 to the right while holding the leading end portion R1 of the label R by suction. In this embodiment, instead of the suction unit 111 pulling out the leading end portion R1 of the label R to the bonding area C and immediately connecting the leading end portion R1 of the label R to the currently consumed label in this embodiment, The leading end portion R1 of the label R is drawn out by a predetermined amount, and the leading end portion R1 of the new label R is connected to the currently consumed label R in a state where the drawn out portion has a margin.

(Connection operation) That is, a new roll 2 is supplied to the supply position B, and the leading end R1 of the label R is cut from the roll 2 by the leading end pulling device 4.
, The suction unit 111 separated from the pressure bonding unit 103 is moved by the control device to the left end position shown by the imaginary line in FIG.
Thus, the suction surface 111a of the suction unit 111 stops at the position of the leading end R1 of the label R at the position of the cutter 79. Then, the control device controls the negative pressure source to control the suction surface 1.
11a, a negative pressure is applied to the leading end R1 of the label R.
Is suction-held on the suction surface 111a. Thereafter, as described above, the suction unit 111 moves rightward and then stops at the position of the tape affixing section 122, so that the air cylinder 115 is operated by the control device, and the leading end of the label R held on the suction surface 111a. The part R1 comes into contact with the tape sticking part 122, whereby the double-sided tape is stuck on one surface of the leading end part R1 of the label R. Thereafter, the operation of the air cylinder 115 is stopped by the control device, and the leading end R1 of the label R is released.
Is held back. Next, the suction unit 1 holding the leading end R1 of the label R in this manner.
11 is moved to the position of the right end of the guide rail 102 shown by the imaginary line in FIG. As a result, the leading end portion R1 of the label R and its subsequent portion are pulled out by substantially the same length as the length of the guide rail 102. Next, when the suction unit 111 is moved to the position of the right end in this way, the pressure bonding unit 103 is on standby at a position opposite to the stopped suction unit 111, and the air cylinder 115 of the connecting means 116 is moved in advance. It is working. Therefore, the suction unit 111 is moved to the right end position and faces the pressure bonding unit 103. Thereafter, the operation of the air cylinder 115 of the connecting means 116 is stopped, so that the engaging member 117 descends to a horizontal state and engages with the engaging protrusion 111b on the suction unit 111 side. As a result, the units 103 and 111 are integrally connected. During this time, the label R of the roll body 2 at the consumption position A is continuously drawn out and consumed, and the currently consumed label R and the new label R drawn out by the suction unit 111 are attached to the bonding area C. It will be located. Next, in the present embodiment, the air cylinder 108 is operated,
The sliding block 104 is moved from the position shown by the imaginary line to the position shown by the solid line on the left, and thereafter the two units 103 and 111 integrated as described above are moved to the standby position shown by E in FIG. Let go left until An air nozzle 123 that blows air from the upper side to the lower side in FIG. 9 toward the label R held by the suction unit 111 is provided on the left side of the standby position. Therefore, the front end portion R1 of the label R and its subsequent portion are maintained in a U-shaped slack state toward the lower side in FIGS. 9 and 1 by the air blown out from the nozzle 123. The U-shaped portion of the label R is temporarily stored in the U-shaped accumulation zone 124 shown in FIG. When it is detected from this standby state that the label R of the roll body 2 at the consumption position A is almost consumed by the sensor provided at the consumption position A in FIG. When the moving speed of 103 and 111 becomes the same as the moving speed of the label R consumed from the consumption position A, the air cylinder 115 is advanced. Thereby, the suction unit 11
Since the leading end portion R1 of the new label R held at 1 is pressed against the currently consumed label R located between the new label R and the crimping surface 103a of the crimping unit 103, the press-contact portion is adhered with a double-sided tape. Immediately after this, the old label R, which is on the rear side adjacent to the bonding point of the new and old labels R,
(The label R on the consumption position A side) is cut by the cutting mechanism 125 provided in the pressure bonding unit 103. In this way, the connection of the new and old labels R is completed in the bonding area C, but both units 103 and 111 moving rightward move to the right end position shown in FIG. 9 and stop.

Next, the cutting mechanism 125 provided in the crimping unit 103 will be described. As shown in FIGS. 11 to 1, the cutting mechanism 125 according to the present embodiment includes a cutter 126 that can lift and lower the label R, and when cutting the label R with the cutter 126, the new and old label R from above. And a back guide 127 inserted therebetween. FIG.
, The cutter 126 and the back guide 127
Is advanced from the retracted position to the advanced position at the time of the above-described cutting, and is supported above the currently consumed label R. Thereafter, the back guide 127 is lowered by the cylinder 128 interlocked with the back guide 127 and inserted between the new and old labels R.
Since the cutter 126 is lowered by the cylinder 129 linked to the cylinder 26, a portion of the label R that is currently consumed, on the rear side of the connection portion, is cut. Both cylinders 128 and 129 and cutting mechanism 12
The operation of a drive source (not shown) for moving the whole 5 forward and backward is also controlled by the control device. Thereafter, the entire cutting mechanism 125 is retracted to the retracted position, and the cutter 126 and the back guide 127 return to the raised position.
Thus, since the cutting mechanism 125 includes the back guide 127, the old label R can be reliably cut without contacting the new and old labels R when the cutter 126 cuts.

When the connection of the new and old labels R is completed in the connection area C by the connection device 5 as described above, the label R of the new roll body 2 at the supply position B is pulled out by the labeler. It is necessary to move the roll 2 at the supply position B to the consumption position A. Therefore, when the connection of the label R by the connection device 5 is completed, the control device firstly operates the air cylinder 10 shown in FIG.
8, the sliding block 104 is returned from the position shown by the solid line to the position shown by the imaginary line at the center. Further, the movable guide 73 of the above-mentioned leading end pulling device 4 is lowered to a lower position below the fixed guide 71. Thereafter, the supply of the compressed air to the engagement pins 29 of the rotating plate 12 at the consumption position A is stopped, so that the cylindrical member 6 of the roll body 2 at the consumption position A is released from the holding state by the engagement pins 29. You. Thereafter, since the rotating plate 12 at the consumption position A is swung from the horizontal state to the vertical state, the roll body 2 having little label R placed on the rotating plate 12 falls off the rotating plate 12 and is collected. Is stored in the box. Thereafter, the rotating plate 12 is returned to the original horizontal state. Then, since the rotating body 11 is rotated 180 degrees in the counterclockwise direction, the rotating plate 12 that does not hold the roll 2 moves from the consumption position A to the supply position B, and the rotating plate that holds the new roll 2 13 moves from the supply position B to the consumption position A. At this time, the movable guide 73 is lowered, and the sliding block 104 is located at the above-described normal position.
No. 04, it moves to the consumption position A.

As described above, the roll feeder 3 of the present embodiment holds the upper and lower sides of the roll 2 of the stocker 31 by the transfer mechanism 32 and vertically supports the rotary plate 13 (12) at the feed position B. By translating toward,
The roll body 2 is supplied. Therefore, when the roll body 2 is supplied to the rotating plate 13 (12), the label R wound around the roll body 2 is not damaged.
Further, even if the outer diameter of the roll body 2 temporarily stored in the stocker is different, the roll body 2 can be supplied to the rotary plate 13 (12) without any trouble by the roll body supply device 3. In addition, since the upper and lower portions of the roll body 2 are sandwiched and supplied to the rotating plate 13 (12), it is possible to prevent the roll body 2 from falling apart during supply.

Next, according to the leading end drawing device 4 of the present embodiment, when the leading end portion R1 of the label R is pulled out, the leading end portion R1 of the label R is held between the driving roller 72 and the guide roller 60 of the movable guide 73. Release the state once, and
The leading end R1 of the drive roller 72 into the free state,
The tip R1 is held between the guide roller 60 and the guide roller 60. Because of this, the tip R1 of the label R
The subsequent portion does not meander in the vertical direction, and is drawn out reliably in a horizontal state. As described above, according to the leading end pulling device 4 of the present embodiment, the leading end portion R1 of the label R can be pulled out with the side portions reliably horizontal. In the above embodiment, the fixed guide 71 is fixed, and the movable guide 73 is moved to the front position and the rear position. However, the movable guide 73 is fixed and the fixed guide 71 is moved to the left and right. Is also good. Further, the drive roller 72 and the guide roller 60 may be provided on the guide on the side opposite to the above embodiment.

Further, according to the connection device 5 of this embodiment,
After the leading end R1 of the label R is pulled out by the suction unit 111, the units 103 and 111 are returned to the standby position and made to stand by, so that the drawn label R can be stored in the accumulation zone 124. In this state, both units 103 and 111 are moved rightward to connect the new and old labels, so that the moving speed of both units 103 and 111 when traveling rightward from the standby position can be increased. Further, the label R
When holding the tip R1, the holding force can be held with a weaker holding force than that of the above-described conventional device. Thus, the configuration in the vicinity of the suction surface 111a as a holding unit for holding the leading end portion R1 of the label R can be simplified and downsized.
