Description

[0001]
[Industrial application fields]
The present invention relates to a leading edge drawing device for a belt-shaped material, and more particularly to a leading edge drawing device for horizontally pulling a leading edge portion of a belt-shaped material wound around a cylindrical member without meandering up and down.
[0002]
[Prior art]
Conventionally, a labeler that attaches a label to the body of a container is well known. In such a labeler, a continuous label in a strip shape wound around a cylindrical member is drawn and sequentially cut into a predetermined length by the labeler. After that, the cut individual labels are stuck on the container.
In such a conventional labeler, when all the strip-like labels drawn from the roll body are consumed, the old roll body is removed and a new roll body is supplied, and the labels of the old and new roll bodies are used. I try to connect.
[0003]
[Problems to be solved by the invention]
By the way, conventionally, the roll body is arranged so that its axis is in the vertical direction, and a belt-like label is drawn from the roll body in that state. Therefore, when a new roll body is supplied and connected to the label of the old roll body, the new roll body is also supported so that its axis is in the vertical direction, and then the leading end of the label is pulled out.
However, when pulling out the leading end portion of the label from the new roll body, care must be taken so that the leading end portion that is pulled out does not meander up and down. This is because if the front end of the new label meanders up and down and is connected to the old label, the label on the rear side of the connecting portion is also drawn out in a state of meandering in the up and down direction.
Conventionally, the above-described connection between the old and new labels has been performed by an operator. However, as described above, it has been a very complicated operation to pull out a new label without meandering up and down.
[0004]
[Means for Solving the Problems]
In view of such circumstances, the present invention supports a roll body made of a cylindrical member and a belt-shaped material wound around the cylindrical member and temporarily fixed at the rear side of the tip so that one side of the belt-shaped material is on the upper side. A rotating member that is rotatable, a drive source that rotates the rotating member, and a belt-like shape that is arranged to extend in a predetermined direction from a position close to the outer side of the rotating member and is drawn from a roll body supported by the rotating member. Any one of a first guide that guides the leading end of the material , a second guide that is arranged to face the first guide and guides the belt-shaped material between the first guide, and the first guide and the second guide A driving roller provided on one of the guides and driven to rotate; and a guide roller provided on the other guide,

According to the above-described configuration, when one of the guides is positioned at the front position and the rotating member and the driving roller are rotated, the leading end portion of the belt-shaped material is sandwiched and fed by the driving roller and the guide roller. Thereafter, the rotation of the rotating member and the driving roller is stopped, and then one guide is retracted from the front position to the rear position. Then, since the guide roller is separated from the driving roller, the leading end portion of the belt-like member located between them is in a free state, and the tip portion of the belt-like member and the subsequent portion thereof are substantially horizontal due to their own weight. Maintained in a state.
Thereafter, when one of the guides is again moved to the front position, the belt-like member is again sandwiched between the driving roller and the guide roller. Thereby, the front-end | tip part of the strip | belt-shaped member was pulled out without meandering up and down.
Therefore, the tip of the new belt-shaped material can be pulled out without relying on human hands, and the tip of the belt-shaped material can be pulled out in a surely horizontal state without meandering up and down.

【Example】
Hereinafter, the present invention will be described with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a roll body processing apparatus, which is disposed at an adjacent position of a labeler (not shown) disposed on the upper side of the drawing. In this roll body processing apparatus 1, a roll body 2 is rotatably supported at a consumption position A on the side closer to the labeler, and a strip-shaped label R wound around the roll body 2 is continuously applied by the labeler. It is drawn and consumed. A labeler (not shown) continuously draws the strip-shaped label R from the roll body 2 at the consumption position A, then cuts the strip-shaped label R into a predetermined length, and sequentially cuts the individual labels into the body of the container. It is comprised so that it may stick to a part.
On the other hand, a new roll body 2 is already supplied to the supply position B by a roll body supply device 3 to be described later and is in a standby state.
A tip pull-out device 4 is provided in the vicinity of the supply position B, and the tip pull-out device 4 pulls out the leading end portion of the strip-shaped label R from the new roll body 2 supported at the supply position B without distortion. Can be done.
Further, a connecting device 5 for connecting the old and new labels R is provided at a position on the right side of the leading edge drawing device 4. The connection device 5 is configured to suck and hold the leading end portion of the new label R pulled out by the leading end pulling device 4 by the suction unit 111 and pull it out to the right. At that time, in the connection region C, the leading end portion of the label R of the new roll body 2 is connected to the portion near the end of the old label R currently drawn from the consumption position A, and adjacent to the connecting portion. The subsequent part of the old label R is cut.
In this way, when the label R is consumed from the roll body 2 at the consumption position A, the roll body processing apparatus 1 transfers the label R of the new roll body 2 waiting at the supply position B to the roll at the consumption position A. It is configured to connect to the label R of the body 2. When the old and new labels R are thus connected, the roll body 2 at the consumption position A is discharged, and the new roll body 2 is moved from the supply position B to the consumption position A. The next roll body 2 is supplied to the supply position B by the body supply device 3. Hereinafter, the label R of the new roll body 2 positioned at the consumption position A is drawn out by the labeler.
[0007]
As shown in FIG. 2, the roll body 2 of the present embodiment is composed of a paper cylindrical member 6 serving as a winding core and a continuous label R wound around the roll. The inner surface immediately behind the front end portion R1 of the label R and the inner surface of the label R are temporarily fixed with glue 7, so that the label R wound around the cylindrical member 6 is naturally released from the front end portion R1. To avoid unraveling. In addition, a register mark R2 is attached to one side of the label R on the right side in FIG. 2 at predetermined intervals in the longitudinal direction. Further, since the axial length of the cylindrical member 6 is set to be the same as the width of the label R, the overall shape of the roll body 2 is a columnar shape that is short in the axial direction. In this embodiment, at the consumption position A and the supply position B, the label R is pulled out in a state where the entire roll body 2 is tilted horizontally so that one side of the label R with the register mark R2 is on the upper side. I am doing so.
[0008]
Next, each component of the roll body processing apparatus 1 will be described. The roll body processing apparatus 1 includes a rotating body 11 that is rotated 180 degrees counterclockwise around D as a rotation center. The rotating plates 12 and 13 are located at positions shifted from each other by 180 degrees on the upper surface of the rotating body 11. Is rotatably provided. The roll body 2 is supported on the rotating plates 12 and 13. The rotating plates 12 and 13 stop at the consumption position A and the supply position B described above each time the rotating body 11 is rotated 180 degrees counterclockwise.
[0009]
As shown in FIG. 3, the rotating body 11 is pivotally supported by a bearing 15 attached to the frame 14 so as to be rotatable counterclockwise around D as a rotation center. A large-diameter gear 16 surrounding the rotation center D is attached to the inner portion of the rotating body 11, and the gear 16 is linked to a motor 17 via a reduction gear (not shown). When the motor 17 is driven to rotate, the rotating body 11 is rotated by 180 degrees counterclockwise in FIG. 1, whereby the rotating plates 12 and 13 are moved to the consumption position A and the supply position. It is located alternately with B.
[0010]
As shown in FIG. 4, a through hole 13a is formed at the center of the rotating plate 13, and a block-like support member 21 is connected to the center of the back surface of the rotating plate 13 so as to cover the through hole 13a. Further, a support shaft 22 is integrally attached to the back surface of the support member 21 so as to coincide with the axis of the rotating plate 13.
The support shaft 22 is passed through the cylindrical portion 23 a on the swing member 23 side, and is rotatably supported by a pair of bearings 24. A large-diameter gear 25 is attached to the support member 21, and a small-diameter gear 27 interlocked with the motor 26 is engaged with the gear 25. Thereby, when the motor 26 is driven, the rotating plate 13 and the roll body 2 supported thereon can be rotated in the clockwise direction. When the rotating plate 13 is positioned at the consumption position A and the label R of the roll body 2 is pulled out by the labeler as described above, the rotation of the rotating plate 13 is slightly resisted, whereby the label R is pulled out with a substantially constant tension.
Next, the swinging member 23 that pivotally supports the rotating plate 13 is disposed on the upper surface of the rotating body 11 so that the longitudinal direction thereof is orthogonal to the radial direction of the rotating body 11, and the length of the swinging member 23 is long. Both ends in the direction are supported in a swingable manner by a pair of bearings 28 provided on the upper surface of the rotating body 11. The oscillating member 23 is interlocked with a cylinder (not shown) provided on the upper surface of the rotating body 11, and is rotated forward and backward by 90 degrees in conjunction with this cylinder. In a state where the cylinder interlocked with the swing member 23 is not operated, the cylindrical portion 23a of the swing member 23 is supported in the vertical direction, and at that time, the rotating plate 13 is supported horizontally. On the other hand, when the cylinder interlocked with the swing member 23 is rotated forward, the swing member 23 is rotated 90 degrees, so that the rotating plate 13 is rotated 90 degrees from the horizontal state and supported in the vertical direction. It has become. When the cylinder is reversed from this state, the swinging member 23 is reversed 90 degrees, so that the rotating plate 13 returns to the original horizontal state.
[0011]
Further, as shown in FIG. 4, the shaft portion of the support member 21 connected to the rotating plate 13 is provided with holding means including a set of three engagement pins 29 arranged at equal circumferential positions. The leading end portions of the engaging pins 29 constituting these holding means are protruded outward through the through holes 13a of the rotating plate 13. The base portion of each engagement pin 29 can move in the radial direction of the rotary plate 13 along the radial guide groove 21a on the support member 21 side. Each guide groove 21a is provided with a compression spring, whereby the engaging pin 29 in each guide groove 21a is always urged radially inward. The engagement pin 29 in each guide groove 21 a communicates with a compressed air supply source (not shown) via an air passage 30 provided over the support member 21 and the support shaft 22.
In a state where compressed air is not applied to 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 is applied to each engagement pin 29 from a compressed air supply source (not shown) via the air passage 30, the engagement pins 29 in each guide groove 21a are synchronized radially outward. It is designed to be moved toward. As shown in FIG. 4, if compressed air acts on each engagement pin 29 from the 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. Since 29 is pressed against the inner peripheral portion of the cylindrical member 6, the roll body 2 can be held on the rotating body 13 by the three engagement pins 29. Further, if the supply of compressed air to each engagement pin 29 is stopped from this state, the three engagement pins 29 are returned to their original inward positions by the springs. The roll member 2 is separated from the inner peripheral portion of the cylindrical member 6, thereby releasing the holding state of the roll body 2 by the three engagement pins 2.
The above description is about the rotating plate 13 at the supply position B on the lower side in FIG. 4, but the rotating plate 12 positioned at the other consumption position A is also configured similarly to the rotating plate 13. The description of the configuration on the other rotating plate 12 side is omitted. That is, in this embodiment, a pair of rotary plates 12 and 13 having the same configuration are provided at positions shifted from each other by 180 degrees, and the roll body 2 supported on one of them is positioned at the consumption position A, The new roll body 2 is held by the other one located at the supply position B. In addition, after the connection of the old and new labels R is completed by the connecting device 5, the rotating body 12 in which the label R is almost consumed is supported on the rotating plate 12 located at the consumption position A. By stopping the supply of compressed air to each engagement pin 29, the holding state of the cylindrical member 6 of the roll body 2 by each engagement pin 29 is released. Then, since the rotating plate 12 located at the consumption position A is moved from the horizontal state toward the vertical direction, the roll body 2 which is substantially only the cylindrical member 6 is dropped from the rotating plate 12, It is discharged into a collection box (not shown) provided outside the rotating body 11.
[0012]
Next, the roll body supply device 3 will be described with reference to FIGS. 1, 5, and 6. The roll body supply device 3 includes a stocker 31 that temporarily stores a plurality of roll bodies 2. A delivery mechanism 32 that is provided so as to be movable in the longitudinal direction and delivers the roll body 2 positioned at the forefront near the supply position B to the rotating plate 13 at the supply position B is provided.
The stocker 31 is fixed to the upper surface of a horizontally supported lifting frame 33, and a delivery mechanism 32 is also provided on the lifting frame 33. The elevating frame 33 has guide shafts 34 fixed vertically downward at a plurality of locations at the bottom thereof, and these guide shafts 34 are slidably passed through a cylindrical guide 36 on the fixed frame 35 side. Further, a screw shaft 37 is rotatably attached to the center of the bottom of the elevating frame 33 so as to be vertically downward, and a lower portion of the screw shaft 37 is screwed into and passed through a nut member 38 on the fixed frame 35 side. ing. A motor 41 is disposed on the fixed frame 35, and the drive shaft of the motor 41 and the screw shaft 37 are interlocked via a pair of bevel gears 42, 42. Thereby, by rotating the motor 41 forward and backward by a required amount, the lifting frame 33 and the stocker 31 and delivery mechanism 32 provided on the lifting frame 33 can be lifted by a required amount.
[0013]
The stocker 31 is fixed to the elevating frame 33 so that the longitudinal direction thereof is parallel to the X direction shown in FIG. 1, and includes a pair of support portions 31a and 31b. The support portions 31a and 31b are inclined in a valley shape while maintaining a predetermined interval. A plurality of roll bodies 2 are supported on the support portions 31a and 31b in a direction in which the axis is horizontal. A semicircular plate 43 is supported and connected to a portion on the rear side of the support portions 31a and 31b on the right side in FIG. The plurality of roll bodies 2 placed on the support portions 31 a and 31 b are in close contact with each other at the adjacent positions, and the most rear side roll body 2 is in contact with the plate 43. In this way, by bringing the most rear roll body 2 into contact with the plate 43, the plurality of roll bodies 2 supported by the stocker 31 are prevented from falling over.
[0014]
Next, a pair of guide rails 44 is attached to the elevating frame 33 in parallel with the longitudinal direction of the stocker 31, and a movable frame 45 constituting the delivery mechanism 32 is movably attached to these guide rails 44. . The movable frame 45 is generally U-shaped, and the lower horizontal portion 45a is positioned on the lower side orthogonal to the support portions 31a and 31b of the stocker 31, while the upper horizontal portion of the movable frame 45 is horizontal. The part 45b is located above the roll body 2 orthogonal to both the support parts 31a and 31b of the stocker 31.
Further, between the guide rails 44 on the upper surface of the elevating frame 33, a screw shaft 39 is rotatably supported in parallel with them, and the nut member is attached to the horizontal portion 45a of the movable frame 45. 46 is screwed through. The screw shaft 39 is rotated forward and backward in conjunction with a motor (not shown) provided on the elevating frame 33. Then, as the motor interlocked with the screw shaft 39 is rotated in the forward and reverse directions, the movable frame 45 is moved backward in the forward direction indicated by the solid line on the left side in FIG. It is moved along the longitudinal direction of the stocker 31 between the end positions.
[0015]
An air cylinder 47 is attached to the lower horizontal portion 45a of the movable frame 45 in a vertically upward direction, and a clamping member 48 having an arcuate 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 face vertically downward, and a clamping member 52 whose bottom surface has an arc shape is connected to the lower end portion of the air cylinder 51. The sandwiching members 48 and 52 face each other, and as can be understood from FIGS. 5 and 6, the sandwiching member 48 on the lower side is positioned on the lower side adjacent to the lower end portion of the roll body 2 supported by the stocker 31. It is supposed to be. Further, the upper clamping member 52 is positioned close to the upper side of the upper end portion of the roll body 2 supported by the stocker 31. As can be understood from FIG. 6, the thicknesses (X-direction dimensions) of the clamping members 48 and 52 are set to be the same as or slightly smaller than the width of the label R of the roll body 2.
[0016]
Further, as shown in FIG. 6, a sensor 53 is provided on the upper horizontal portion 45b, and the movable frame 45 is moved to the right side from the forward end position shown by the solid line, and the holding members 48, 52 are used to hold the stocker 31. When the foremost roll body 2 is to be clamped, the foremost roll body 2 can be detected in response to the cylindrical member 6 of the roll body 2. And if the sensor 53 detects the cylindrical member 6 of the roll body 2 and stops the movement of the movable frame 45, the clamping members 48 and 52 will stop in the up-and-down position of the roll body 2 of the foremost position. Yes.
[0017]
Further, in this embodiment, the lower air cylinder 47 provided on the movable frame 45 is provided with a sensor 54 for detecting the advance amount, that is, the rising amount of the clamping member 48.
In the present embodiment, the delivery mechanism 32 is constituted by the movable frame 45, the clamping members 48 and 52 provided on the movable frame 45, the sensors 53 and 54, and the like.
The roll body supply device 3 includes a delivery mechanism 32, a stocker 31, and a rotating plate 13 at a supply position B.
[0018]
(Delivery operation)
The supply operation of the roll 2 by the roll body supply device 3 configured as described above will be described.
That is, first, after the end of the old label R of the roll body 2 at the consumption position A and the front end of the label R of the new roll body 2 already waiting at the supply position B are connected by the connecting device 5 described later, When the rotating body 11 is rotated counterclockwise, the connected roll body 2 is positioned at the consumption position A, while the empty rotating plate 13 stops at the supply position B. Thereafter, since the motor interlocked with the swinging member 23 shown in FIG. 4 is rotated forward, the horizontal rotating plate 13 is moved until it becomes the vertical direction as shown in FIG. Thereby, the rotating plate 13 is in a state of facing the foremost roll body 2 supported by the stocker 31. At this time, the three engagement pins 29 on the rotating plate 13 side are supported horizontally. At this time, since the compressed air is not applied to the engagement pin 29, 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 stands by at the forward end position indicated by a solid line in FIG. 6, and the air cylinders 47 and 51 provided on the movable frame 45 are not operated. As described above, when the rotating plate 13 at the supply position B is supported in the vertical direction, the motor interlocked with the screw shaft 39 of the delivery mechanism 32 is reversed, so that the movable frame 45 is indicated by an imaginary line from the forward end position. Retreats along the rail 44 toward the retracted end position. Then, 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 in this way, the reverse rotation of the screw shaft 39 is stopped. Is done. Accordingly, the clamping members 48 and 52 are positioned at the upper and lower positions of the roll body 2 at the foremost position.
[0019]
After this, first, the upper air cylinder 51 is actuated, so that the clamping member 52 is lowered and pressed against the upper end of the label R of the roll body 2 at the foremost position.
Next, since the lower air cylinder 47 is actuated, the lower clamping member 48 comes into pressure contact with the lower end portion of the label R of the roll body 2 at the foremost position (see FIG. 5). As a result, the label R of the roll body 2 is held between the holding members 52 and 47 in the vertical position. Here, in the present embodiment, the lower air cylinder 47 is larger than the upper air cylinder 51, and therefore the air cylinder 51 is moved up to the retracted end by raising the air cylinder 47. Therefore, the roll body 2 is lifted from the stocker 31 in a state where the roll body 2 is sandwiched by the sandwiching members 52 and 47 at the upper and lower positions, and is supported at a predetermined height. That is, the foremost roll body 2 is taken out from the stocker 31 by the both clamping members 48 and 52.
[0020]
In this state, the height of the cylindrical member 6 in the roll body 2 sandwiched between the both sandwiching members 48 and 52 and the height of the engaging pin 29 on the rotating plate 13 side supported in the vertical direction do not match. Even if the movable frame 45 is moved again to the forward end position in this state, the three engagement pins 29 are not inserted into the cylindrical member 6 in the roll body 2. Therefore, in this embodiment, the advance amount of the air cylinder 47 on the lower side is detected by the sensor 54, whereby the lifting frame of the cylindrical member 6 in the roll body 2 sandwiched between the both sandwiching members 48 and 52. 33, and the amount of deviation between the height of the cylindrical member 6 and the engaging pin 29 on the rotating plate 13 side is calculated. Then, by rotating the motor 41 forward and backward by a required amount, the entire lifting frame 33 is moved up and down by the calculated amount of deviation. Thereby, the height of the cylindrical member 6 in the roll body 2 clamped by the both clamping members 48 and 52 coincides with the height of the engaging pin 29 on the rotating plate 13 side supported in the vertical direction.
Thereafter, since the motor interlocked with the screw shaft 39 is rotated forward, the movable frame 45 stops after being moved to the forward end position indicated by the solid line. As a result, the roll body 2 sandwiched between the sandwiching members 48 and 52 abuts against the rotating plate 13 in a state of being opposed thereto, and the three engaging pins 29 on the rotating plate 13 side are the cylindrical members 6 of the roll body 2. Is inserted inward.
[0021]
Then, since compressed air acts on each engagement pin 29 of the rotating plate 13, each engagement pin 29 is moved toward the outer side in synchronization and is pressed against the inner peripheral portion of the cylindrical member 6. Thereby, the roll body 2 is held by the three engagement pins 29 as holding means.
[0022]
Thereafter, the operations of the air cylinders 47 and 51 on the movable frame 45 side are stopped, so that both the clamping members 52 and 47 are returned to the retracted position, and the roll body 2 is released from the both clamping members 52 and 47.
Thereafter, the rotating plate 13 holding the roll body 2 is rotated 90 degrees from the vertical state shown in FIG. 6 and returned to the 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, compressed air is applied again to each engagement pin 29. The cylindrical member 6 of the roll body 2 is securely held by the joint pin 29. As a result, the 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 the new roll body 2 to the rotary plate 13 (12) supported in the vertical direction at the supply position B.
[0023]

Next, based on FIGS. 3, 4, 7, and 8, the leading edge drawing device 4 that pulls the leading edge R <b> 1 of the label R from the roll body 2 supported by the rotating plate 13 at the supply position B will be described.
[0024]
As shown in FIG. 7, the leading-end drawer device 4 is provided with a substantially arcuate fixed guide 71 provided in the vicinity of the outer peripheral portion of the rotating plate 13 at the supply position B, and rotatably provided at a predetermined position of the fixed guide 71. And a movable guide 73 having a small-diameter guide roller 60 in contact with the drive roller 72.
The roll body 2 is supported on the rotating plate 13 at the supply position B so that one side of the label R with the register mark R2 is on the upper side. The rotating plate 13 supporting the roll body 2 is shown in FIG. When the motor 26 shown is operated, it is rotated in the clockwise direction. Along with this, the leading end R1 of the label R is slid and guided by the fixed guide 71, and then inserted into the gap 78 between the driving roller 72 and the leading end 73b of the movable guide 73.
As shown in FIG. 8, the fixed guide 71 is horizontally attached to the upper end of the support shaft 74 erected on the rotating body 11. The guide surface 71a of the fixed guide 71 is close to the outer peripheral portion of the rotating plate 13 over a region that is approximately a quarter of the outer peripheral portion of the rotating plate 13, and further toward the connection device 5 side on the right side. Are stretched linearly. In the present embodiment, the plurality of thin plate members are arranged at equal intervals in the vertical direction, and the fixed guide 71 is formed by connecting the plurality of thin plate members with a plurality of connection bolts.
A driving roller 72 is rotatably provided at a location where the guide surface 71a of the fixed guide 71 changes from an arc shape to a linear shape. The outer peripheral surface of the drive roller 72 is slightly protruded toward the rotating plate 13 than the guide surface 71 a of the fixed guide 71. A pulley 75 is attached to the lower end of the drive roller 72 (FIG. 3), and this pulley 75 is linked to a motor 77 (see FIG. 4) provided on the rotating body 11 via an endless belt. When the motor 77 is operated, the drive roller 72 is rotated counterclockwise.
[0025]
Next, the movable guide 73 is arranged along the region where the guide surface 71a of the fixed guide 71 is linear and close to the guide surface 71a. As shown in FIG. 8, the movable guide 73 is configured by connecting a plurality of plate-like members with bolts, similarly to the fixed guide 71. A portion facing the linear region of the guide surface 71 a of the fixed guide 71 is a guide surface 73 a of the movable guide 73.
The movable guide 73 can be moved up and down to an upper position that is the same height as the fixed guide 71 and a lower position shown in FIG. 8 that is lower than that, and a solid line in FIGS. And the reciprocating position retracted to the right by a predetermined amount from the advancing position can be translated along the fixed guide 71.
[0026]
As shown in FIG. 7, the left end portion 73b of the movable guide 73 is sharpened in a V shape, and a guide roller 60 is rotatably provided at a position adjacent to the end portion 73b. When the movable guide 73 is supported at an upper position that is the same height as the fixed guide 71 and is in the advanced position, the guide surface 73a at the distal end portion 73b of the movable guide 73 and the guide surface 71a of the fixed guide 71 move leftward. A V-shaped gap 78 having a widened side is formed. At this time, the guide roller 60 adjacent to the gap 78 is in pressure contact with the drive roller 72, and the guide surface 71 a of the fixed guide 71 and the guide surface of the movable guide 73 are positioned on the right side of these contact portions. The state where the distance 73a is slightly separated from the thickness of the label R is maintained.
When the rotating plate 13 is rotated clockwise from this state and the driving roller 72 is rotated counterclockwise, the leading end R1 of the label R supported by the rotating plate 13 slides on the guide surface 71a of the fixed guide 71. It is moved and guided in the clockwise direction, and is eventually inserted into the gap 78. Thereafter, the leading end portion R1 of the label R is sandwiched between the driving roller 72 and the guide roller 60 by the rotation of the driving roller 72 and then pulled out toward the right side, and the guide surface 71a of the fixed guide 71 It is inserted between the guide surface 73 a of the movable guide 73 and pulled out further to the right side from the right end of the guide surface 71 a of the fixed guide 71.
[0027]
As shown in FIG. 7, an air nozzle 81 that ejects air is provided at a position adjacent to the movable guide 73, and when the drive roller 72 is rotated, the air nozzle 81 faces a gap 78 on the left side. To blow out air. As a result, when the leading end R1 of the label R moves toward the gap 78 along the guide surface of the fixed roller 71, the leading end R1 of the label R opens toward the outside. The leading end R1 of the label R is surely inserted into the gap 78.
[0028]
As shown in FIGS. 7 and 8, a sensor 82 is provided at a predetermined position of the movable guide 73 so as to be orthogonal to the guide surface 73a. As described above, the driving roller 72 and the guide roller 60 are in contact with each other. When the leading end R1 of the label R is pulled out to the right between the guide surfaces 71a and 73a by the rotation of the drive roller 72, the sensor 82 is attached to the register mark R2 (see FIG. 2). ) Is detected.
Also, a conventionally known cutter 79 is provided on the extension line of the right end portion of the fixed guide 71, and the leading end of the label R drawn to the right side from the right end portion of the fixed guide 71 is provided. The portion R1 is supported by the cutter 79 so that it can be cut. Further, the cutter 79 is provided with a tape adhering portion 122 for adhering a double-sided tape to one surface of the tip portion R1.
[0029]
Next, a mechanism and a lifting mechanism for moving the movable guide 73 in the left-right direction on the drawing 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 in the vertical direction in the rotating body 11, and the screw shaft 85 is screwed through a nut member (not shown) provided on the elevating plate 83. The screw shaft 85 is interlocked with the motor 86 through a pulley and an endless belt provided at the lower end thereof. By rotating the motor 86 forward and backward by a required amount, the movable guide 73 provided on the elevating plate 83 is positioned at an upper position where it is at the same height as the fixed guide 71 and the drive roller 72, and the fixed guide 71 shown in FIG. Can be raised and lowered to a lower position.
[0030]
Further, a pair of guide rails 87 are provided on the upper surface of the lifting plate 83 so as to be parallel to the linear portion of the guide surface 71 a of the fixed guide 71, and the bottom of the movable guide 73 is connected to these guide rails 87. It is placed so that it can move. As a result, 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 when seen in a plan view 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 in the upper position, the guide surface 73a of the movable guide 73 and the fixed guide 71 A gap that allows the label R to be substantially inserted is maintained between the linear portion of the guide surface 71a.
As described above, the movable guide 73 placed on the guide rail 87 is connected to the air cylinder 88 provided on the lifting plate 83 (FIG. 7). The air cylinder 88 is in a retracted position in a non-operating state, and is advanced to the forward end when operated. 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 retracted position to the advanced position shown in FIG. It has become.
When the movable guide 73 is at an upper position where it is at the same height as the fixed guide 71, and the air cylinder 88 is actuated and the movable guide 73 is in the forward position, the guide roller 60 of the movable guide 73 is the outer periphery of the drive roller 72. 7 between the guide surface 73a of the movable guide 73 and the linear portion of the guide surface 71a of the fixed guide 71, which is on the right side in FIG. A gap equivalent to the number of sheets is maintained.
[0031]
(Description of operation)
The operation of the tip leading-out device 4 configured as described above will be described.
First, the movable guide 73 is supported at an upper position that is the same height as the fixed guide 71, and the air cylinder 88 is in an inoperative state. That is, at this time, the movable guide 73 is waiting in the retracted position, and the guide roller 60 is not in pressure contact with the drive roller 72. On the other hand, the rotating plate 13 at the supply position B supports the new roll body 2.
From this state, the rotating plate 13 is rotated clockwise and the driving roller 72 is rotated counterclockwise. At the same time, the air cylinder 88 is operated to position the movable guide 73 at the forward position. As a result, the guide roller 60 of the movable guide 73 is pressed against the drive roller 72, and a V-shaped gap 78 is maintained between the guide surface 71 a of the fixed guide 71 and the distal end portion 73 b of the movable guide 73.
Thereafter, as the rotating plate 13 is rotated in the clockwise direction, 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 that 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 to the outer side and is surely inserted into the V-shaped gap 78.
[0032]
Since the driving roller 72 is rotated, the leading end portion R1 of the label R is sandwiched between the driving roller 72 and the guide roller 60, and then is guided between the guide surface 71a of the fixed guide 71 and the guide surface 73a of the movable guide 73. Guided and pulled out to the right between them.
When the first register mark attached to the label R is detected by the sensor 82 in the process of pulling out the leading end R1 of the label R in this way, the rotation of the driving roller 72 and the rotating plate 13 is temporarily stopped and the label R The drawing of R is temporarily stopped and the operation of the air cylinder 88 is also stopped.
Thereby, the movable guide 73 moves to a rear position shifted by a predetermined amount from the front position indicated by the solid line to the right. Therefore, since the driving roller 72 and the guide roller 60 of the movable guide 73 are separated from each other, the label R positioned between them is released. Therefore, the front end portion R1 of the label R and the subsequent portion thereof are corrected so that the side portion in the longitudinal direction thereof becomes substantially horizontal by its own weight.
[0033]
Thereafter, the air cylinder 88 is actuated again, and the movable guide 73 is moved to the forward position, so that the label R is sandwiched again by the guide roller 60 and the drive roller 72 of the movable guide 73. That is, the label R is sandwiched between the movable guide 73 and the drive roller 72 in a state where the longitudinal side portion is substantially horizontal without meandering up and down, and from this state, the rotary plate 13 and The drive roller 72 is rotated.
As a result, the label R is further pulled out. However, 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 portion R1 of the new label R, and the length from the leading end portion R1 of the label R to the first register mark is aligned to a predetermined length.
As a result, the front end portion R1 of the label R and its subsequent portion are pulled out in a horizontal state without meandering up and down by the front end pulling device 4.
[0034]
(Connecting device)
Next, the connecting device 5 that connects the leading end R1 of the label R pulled out from the supply position B by the leading end pulling device 4 and the label R that is currently being drawn out from the consumption position A 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 that are 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 attached to the center of the bottom surface of the elevating frame 91, and an upper portion of a screw shaft 95 rotatably provided on the fixed frame 14 on the lower side is screwed into the nut member 94. The screw shaft 95 is interlocked with a rotation shaft 98 on the handle 97 side via a pair of bevel gears 96. That is, by rotating the handle 97 forward and backward by a required amount, the lifting frame 91 and the entire connecting device 5 provided thereon can be lifted and lowered by the required amount.
[0035]
As shown in FIGS. 1, 3, 9, and 10, the connecting device 5 includes a pair of guide rails 101 and 102 that extend from the upper side of the distal end drawing device 4 toward the right side. 101 and 102 are horizontally attached to the lift frame 91.
The crimping unit 103 is movably attached to one guide rail 101, and the sliding block 104 is movably attached to a position closer to the rotating body 11 than the crimping unit 103. A rotatable engagement roller 105 is attached to the sliding block 104. The label R drawn out and consumed from the consumption position A is hooked on the idler roller 106 on the rotating body 11 side, and is then hooked on the engagement roller 105 of the sliding block 104 and then between the guide rails 101 and 102. They are pulled out in parallel with them, and further pulled out toward a labeler (not shown) after being hooked on a plurality of idle rollers 107 provided at positions adjacent to the connection device 5.
An air cylinder 108 is provided at a position adjacent to the left end of the guide rail 101 (FIG. 9), and the air cylinder 108 is connected to the sliding block 104. In the non-operating state of the air cylinder 108, the sliding block 104 is positioned on the side indicated by the imaginary line in FIG. 9, but when the air cylinder 108 is operated when necessary, the left side indicated by the solid line in FIG. It is moved to the side position. The operation of the air cylinder 108 is controlled by a control device (not shown).
When the crimping unit 103 is connected to a suction unit 111, which will be described later, the air cylinder is moved from the position indicated by the imaginary line on the right side of FIG. 9 to the position of the imaginary line on the left side. 108 is operated to move the sliding block 104 to the position of the solid line in FIG. 9, so that the crimping unit 103 does not collide with the sliding block 104.
[0036]
On the other hand, a suction unit 111 is movably attached to the guide rail 102, and a ball screw 112 is rotatably supported in parallel with the guide rail 102 at a position adjacent to the guide rail 102. The ball screw 112 is threaded through the threaded portion of the suction unit 111. The ball screw 112 is interlocked with the motor 114 via the timing belt 113. The operation of the motor 114 is controlled by a control device (not shown), and the suction unit 111 can be reciprocated along the guide rail 102 by rotating the motor 114 forward and backward by the control device.
[0037]
(Configuration of suction unit 111)
The suction unit 111 is provided with a suction surface 111a that sucks and holds the leading end R1 of the label R, and this suction surface 111a is positioned in the vicinity of the label R that is currently consumed. On the other hand, on the pressure bonding unit 103 side, a flat pressure bonding surface 103a is provided at a position facing the suction unit 111 with the label R interposed therebetween.
The suction surface 111a of the suction unit 111 has a plurality of holes for sucking 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 to the negative pressure passage from the negative pressure source, the label R can be sucked and held by the suction surface 111a. When the supply of negative pressure to is stopped, the suction state of the label R by the suction surface 111a is released.
The suction surface 111a is supported at the tip of the air cylinder 115, and the operation of the air cylinder 115 is controlled by a control device (not shown). In the non-operating state of the air cylinder 115, as shown in FIG. 9, the suction surface 111a is separated by a predetermined distance from the pressure bonding surface 103a of the pressure bonding unit 103 that is the opposite position, and the current position of the front surface near the pressure bonding surface 103a It is also separated from the consumed label R. On the other hand, when the air cylinder 115 is actuated and advanced by the control device, the suction surface 111a is advanced to a position where it abuts against the label R and presses it against the crimping surface 103a of the crimping unit 103. Yes.
[0038]
By the way, the crimping unit 103 and the suction unit 111 are integrally connected by connecting means 116 when necessary. That is, as shown in FIG. 10, the engaging member 117 is swingably attached to the upper portion of the crimping unit 103 by the support shaft 118. The engaging member 117 is provided so as to be orthogonal to the guide rail 101, and the air cylinder 121 is connected to the back surface that is the suction unit 111 rather than the support shaft 118. The operation of the air cylinder 121 is also controlled by a control device (not shown). When the air cylinder 121 is not actuated, the engaging member 117 is maintained in a horizontal state. However, when the air cylinder 121 is actuated, the tip of the engaging member 117 on the side of the suction unit 111 is raised and imagined. It is inclined as shown by the line.
A square notch 117 a is provided at the center of the front end of the engaging member 117 on the suction unit 111 side, and on the other hand, a linear engagement protrusion 111 b is formed on the upper portion of the suction unit 111.
Therefore, when the units 103 and 111 are connected together, the controller 111 operates the air cylinder 121 to support the engaging member 117 diagonally, and the suction unit 111 is moved to a position facing the crimping unit 103. From this state, the control device stops the operation of the air cylinder 121. Then, due to the weight of the engaging member 117, the engaging member 17 is in a horizontal state, and the notch 117 a at the tip thereof is engaged with the engaging protrusion 111 of the suction unit 111. Thereby, both units 103 and 111 are connected integrally. When the two units 103 and 111 are separated, if the air cylinder 121 is operated, the notch 117a of the engaging member 117 is detached from the engaging protrusion 111 of the suction unit 111, thereby connecting the units 103 and 111 to each other. Is released.
As described above, the connecting means 116 is constituted by the engaging member 117, the air cylinder 121, and the engaging protrusion 111b.
[0039]
Furthermore, the connecting device 5 of the present embodiment includes a tape adhering portion 122 for attaching a double-sided tape to one surface of the leading end portion R1 of the label R at a position adjacent to the cutter 79 of the leading end drawing device 4 (FIG. 9). ). The tape sticking part 122 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 leading edge drawing device 4 and sucks and holds the leading edge R1 of the label R by the suction surface 111a. The controller moves to the landing portion 122 and temporarily stops. In this state, the control device operates the air cylinder 115 to advance the suction surface 111a. 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 adhering portion 122, and then the operation of the air cylinder 115 is stopped. Further, it is separated from the tape attaching part 122. In this manner, the control device is configured to move the suction unit 111 toward the right while the tip portion R1 of the label R is sucked and held.
In this embodiment, the suction unit 111 does not draw the leading end R1 of the label R to the adhesion region C and immediately connects the leading end R1 of the label R to the currently consumed label. The leading end portion R1 of the label R is pulled out by a predetermined amount, and the leading end portion R1 of the new label R is connected to the label R that is currently consumed in a state where the leading portion has a margin.
[0040]
(Connection operation)
That is, when the new roll body 2 is supplied to the supply position B and the leading end R1 of the label R is pulled out from the roll body 2 to the position of the cutter 79 by the leading end drawing device 4, the state is separated from the crimping unit 103. The suction unit 111 is moved to the left end position indicated by an imaginary line in FIG. 9 by the control device. As a result, 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, since the control device controls the negative pressure source to apply a negative pressure to the suction surface 111a, the leading end R1 of the label R is sucked and held on the suction surface 111a.
Thereafter, as described above, since the suction unit 111 moves to the right and stops at the position of the tape adhering portion 122, the front end of the label R held on the suction surface 111a by operating the air cylinder 115 by the control device. Part R1 contacts tape sticking part 122, and, thereby, a double-sided tape is stuck on one side of tip R1 of label R.
Thereafter, the operation of the air cylinder 115 is stopped by the control device, and the suction surface 111a holding the leading end R1 of the label R moves backward.
Next, the suction unit 111 holding the leading end R1 of the label R in this way 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 R1 of the label R and the subsequent portion thereof are pulled out to the same extent as the length of the guide rail 102.
Next, when the suction unit 111 is moved to the right end position in this way, the crimping unit 103 is waiting at the position opposite to the stopped suction unit 111, and the air cylinder 115 of the connecting means 116 is set in advance. It is operating.
Therefore, the suction unit 111 is moved to the position of the right end and faces the crimping unit 103. Thereafter, since the operation of the air cylinder 115 of the connecting means 116 is stopped, the engaging member 117 is lowered to the horizontal state and engages with the engaging protrusion 111b on the suction unit 111 side. Thereby, both units 103 and 111 are connected integrally.
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 by the suction unit 111 are brought into the adhesive region C. Will be located.
Next, in this embodiment, the air cylinder 108 is actuated to move the sliding block 104 from the position indicated by the imaginary line to the position indicated by the solid line on the left side, and thereafter, as a united state as described above. Both units 103 and 111 are moved to the standby position indicated by E in FIG.
On the left side of the standby position, 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. For this reason, the leading end R1 of the label R and the subsequent portion thereof are maintained in a U-shaped state toward the lower side of FIGS. 9 and 1 by the air blown from the nozzle 123. The U-shaped portion of the label R is temporarily stored in the U-shaped accumulator zone 124 shown in FIG.
When it is detected from the 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. 1, both units 103 and 111 are moved right and both units When the moving speeds 103 and 111 are the same as the moving speed of the label R consumed from the consumption position A, the air cylinder 115 is advanced. As a result, the leading end portion R1 of the new label R held on the suction unit 111 is pressed against the currently consumed label R positioned between it and the crimping surface 103a of the crimping unit 103. Glued by. Immediately after this, the old label R (the label R on the consumption position A side) on the adjacent rear side of the bonding location of the old and new labels R is cut by the cutting mechanism 125 provided in the crimping unit 103.
In this way, the connection between the new and old labels R is completed in the adhesive region C, but both the units 103 and 111 moving to the right move to the right end position shown in FIG. 9 and stop.
[0041]
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 the old and new labels R from above when cutting the label R with the cutter 126. Back guide 127 inserted between the two.
As shown in FIG. 13, the cutter 126 and the back guide 127 are advanced from the retracted position to the advanced position at the time of cutting described above, and are supported above the label R that is currently consumed. 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, and then the cutter 126 is lowered by the cylinder 129 interlocked with the cutter 126. The location on the rear side of the connecting portion in the label R is cut. The operation of the drive source (not shown) that moves the cylinders 128 and 129 and the entire cutting mechanism 125 forward and backward is also controlled by the control device.
Thereafter, the entire cutting mechanism 125 is moved back to the retracted position, and the cutter 126 and the back guide 127 are returned to the raised position. Since the cutting mechanism 125 includes the back guide 127 as described above, the old label R can be reliably cut without contacting the new and old labels R when cutting with the cutter 126.
[0042]
When the connection of the new and old labels R is completed in the connection region C by the connecting 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 body 2 to the consumption position A.
Therefore, when the connection of the label R by the connecting device 5 is completed, the control device first returns the sliding block 104 from the position indicated by the solid line to the position indicated by the imaginary line in the center by the air cylinder 108 shown in FIG. .
Further, the movable guide 73 of the above-described tip leading-out device 4 is lowered to a lower position below the fixed guide 71.
Thereafter, the supply of compressed air to each engagement pin 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 each engagement pin 29. The 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 almost no label R placed on the rotating plate 12 is dropped from the rotating plate 12 and collected. It is stored in a box. Thereafter, the rotating plate 12 is returned to the original horizontal state.
Then, since the rotating body 11 is rotated 180 degrees counterclockwise, the rotating plate 12 not holding the roll body 2 moves from the consumption position A to the supply position B, and the rotating plate holding the new roll body 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. Therefore, the rotating plate 13 does not interfere with the movable guide 73 and the sliding block 104, and the consumption position A Move up.
[0043]
As described above, the roll body supply device 3 according to the present embodiment has the delivery mechanism 32 sandwich the upper and lower sides of the roll body 2 of the stocker 31 toward the rotating plate 13 (12) supported in the vertical direction at the supply position B. The roll body 2 is supplied by moving in parallel.
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 supply device 3 can supply the roll plate 13 (12) without any trouble.
In addition, since the upper and lower sides 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 being scattered during the supply.
[0044]
Next, according to the leading end drawing device 4 of the present embodiment, when the leading end R1 of the label R is pulled out, the clamping state of the leading end R1 of the label R by the driving roller 72 and the guide roller 60 of the movable guide 73 is temporarily set. The leading end R1 of the label R is released, and the leading end R1 is sandwiched between the driving roller 72 and the guide roller 60 again. Thus, the leading end R1 of the label R and the subsequent portion thereof are not meandered in the vertical direction, but are reliably pulled out in a horizontal state.
As described above, according to the leading edge drawing device 4 of the present embodiment, the leading edge R1 of the label R can be reliably pulled out in a state where the side is 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 side is fixed and the fixed guide 71 is moved left and right. Also good. Further, the drive roller 72 and the guide roller 60 may be provided on the guide on the opposite side to the above embodiment.
[0045]
Furthermore, according to the connecting device 5 of the present embodiment, the label R that has been pulled out is stored in the accumulator zone by pulling the leading end R1 of the label R by the suction unit 111 and returning the units 103 and 111 to the standby position. 124 can be stored. In this state, both units 103 and 111 are caused to travel to the right and the old and new labels are connected, so that the moving speed of both units 103 and 111 when traveling to the right from the standby position can be increased.
Further, when the leading end portion R1 of the label R is held by the suction unit 111, it can be held by a holding force weaker than that of the conventional device described above. As a result, the structure in the vicinity of the suction surface 111a can be simplified and miniaturized as a holding means for holding the leading end R1 of the label R.
[0046]
【The invention's effect】
As described above, according to the present invention, the tip of the new belt-shaped material can be pulled out without relying on human hands, and the tip of the belt-shaped material can be reliably placed in a horizontal state without meandering up and down. The effect that it can be pulled out is obtained.
