TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packaging tubular label mounting apparatus for mounting a packaging cylindrical label on an outer peripheral surface of a packaged object such as a bottle or a can.
[0002]
[Prior art]
In general, a tubular label for packaging is attached to the outer peripheral surface of a packaged object (hereinafter, referred to as a container) such as a bottle or a can, so that a product name and a trademark are displayed, decoration by color / pattern, description of contents, Protection and so on are being implemented.
[0003]
This packaging tubular label has a heat-shrinkable synthetic resin film with an inner diameter slightly larger than the outer diameter of the container, and a shrink label formed into a cylindrical shape or an auto-shrinkable synthetic resin film with an inner diameter slightly smaller than the outer diameter of the container. There is a stretch label formed in a tubular shape.
[0004]
The former method of mounting the shrink label on the container is to cover the outer peripheral surface of the container while opening the label with opening means, and then heat and shrink the container with steam or hot air to mount the label on the outer peripheral surface of the container. The latter is applied to the container by attaching the stretch label to the container by opening the label with opening means, and further covering the container while expanding the diameter with the diameter expanding means, utilizing the self-shrinking property. It is performed by a method or an apparatus which is shrunk and mounted on the outer peripheral surface of the container.
[0005]
Both the shrink label and the stretch label are attached to the outer peripheral surface of the container by almost the same method and device, but generally, the shrink label is formed by making the circumference of the cylindrical label longer than the circumference of the container. Since the tubular label is pulled out from the outside by an opening means such as suction and swelled, the tubular label can be opened and covered on the container, and the tubular label in a fixed state does not require the cylindrical label without force. Insertion and wearing / wearing are performed.
[0006]
Further, since the stretch label is formed so that the circumferential length of the tubular label is shorter than the circumferential length of the container, the tubular label is expanded by being pulled from the outside by an opening means such as suction and expanded, and further opened. The diameter of the cylindrical label is increased by using a mounting device having label locking claws and the like, and the cylindrical label is mounted on the container. Is mounted and mounted by pushing up and inserting.
[0007]
Here, the attachment to the cylindrical container will be described using a stretch label as an example.
[0008]
A flat elongated tube having folds on both side edges is formed from a synthetic resin film and wound into a roll, and the elongated tube wound into a roll is fed through a support device such as a rubber roller. This long tube is cut into a predetermined length by a cutter of a cutting device to form a flat tubular label. The flat tubular label is sucked by the suction cups of the pair of suction devices, and the suction cups of the pair of suction devices are separated from each other to form a substantially elliptic cylindrically opened tubular label. Further, the bulged and opened cylindrical label is inserted into a label locking claw provided in a state of being closed and closed by a cylindrical label mounting device arranged below the cylindrical label.
[0009]
Then, by expanding the label locking claw of the mounting device into a predetermined shape, the cylindrical label changes from a substantially elliptical cylindrical shape to a shape adapted to the outer shape of the container, for example, a substantially cylindrical shape or a substantially elliptical cylindrical shape. And expanded. For example, the upper part of the cylindrical label, in which the label locking claw of the mounting device is not inserted, has substantially the same original size. When the suction of the cylindrical label is stopped, the suction device is retracted and returns to the original position.
[0010]
Subsequently, the container is lifted from below by the elevating device with respect to the expanded cylindrical label, and inserted into the inside of the expanded cylindrical label via the label engaging claw of the mounting device, and is attached to the outer peripheral surface of the container. A tubular label is mounted.
[0011]
Thereafter, the container on which the cylindrical label is mounted is gripped by the gripper from the outside of the cylindrical label, and the cylindrical label is lifted by the gripper together, pulled out from the label locking claw of the mounting device, and removed from the outer periphery of the container. A cylindrical label is attached to the surface.
[0012]
When the container with the cylindrical label is released from the gripper, the container is transferred to a predetermined position by the lifting device and the transport device.
[0013]
In this cylindrical label mounting apparatus, a label expanding means having a claw piece provided so as to be able to expand and contract inside a through hole formed in a substrate through which a container passes, and a cylindrical label is inserted outside the claw piece. Label supplying means, a label gripping means for gripping the lower end and the upper end of the cylindrical label, and a container moving means for inserting a container into the through-hole, the label gripping the lower end of the cylindrical label. Hold the container upward, push the container upward, align the lower end of the container label mounting portion with the lower end of the cylindrical label, mount the cylindrical label on the container label mounting portion, and mount the cylindrical label. Later, the grip of the label gripping means is released, the upper end of the cylindrical label attached to the container is gripped again, the cylindrical label is pulled up together with the container, the claw pieces are removed from the cylindrical label, and the elasticity of the cylindrical label is restored. The cylindrical label is mounted on the container by force. One which is known.

However, depending on the timing of the supply, the cylindrical label supplied by the label supply means may not be inserted into the claw, so that the size of the claw can be reduced. This can cause a phenomenon in which the tubular label is inserted into the lower claw support and the cylindrical label is sandwiched between the claw support and the through hole. Further, the replacement of the label expanding means having claws and the substrate due to the change of the shape of the container to which the cylindrical label is mounted and the like are complicated.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a tubular label mounting device of the present invention will be specifically described with reference to the drawings. Note that the present embodiment shows one applied to a stretch label.
[0020]
FIG. 1 conceptually shows each process from mounting a tubular label L to a cylindrical container B from a long tube T using a mounting apparatus of the present invention.
[0021]
A flat elongated tube T having folds on both side edges is formed from a synthetic resin film (not shown) and wound into a roll (not shown), and the elongated tube T is supported by a roll. While being intermittently fed by the feed roller 23 through the device 1 and the feed roller 22, it is passed through the auxiliary opening device 21 of the opening device 2 to expand the primary diameter to separate the folds and uneven flat portions on both side edges, and to extend the length. A predetermined position of the long tube T is cut into a predetermined length by the cutter 241 of the cutting device 24 to form a flat tubular label L. The flat tubular label L is sucked by the suction cups 251 of the pair of suction devices 25, and thereafter, the suction cups 251 of the pair of suction devices 25 are provided in the suction device 25 by an air cylinder or a hydraulic cylinder, or a servo motor ( (Not shown) to form a flat cylindrical label L into a cylindrical label L having an opening that bulges into an almost elliptical cylindrical shape. Transfer to the mounting device 3.
[0022]
The cylindrical label L held in the swelling / opening state by the suction device 25 is held in the swelling / opening state by the suction device 25, and is attached to the label mounting device 3 disposed below the suction device 25. It is inserted into the provided label locking claw 31 in the contracted state.
[0023]
Next, the label locking claw 31 of the label mounting device 3 is expanded to a predetermined shape while the swelling / opening state of the cylindrical label L is continued by the suction device 25. As a result, the cylindrical label L is expanded from the opening that swells into a substantially elliptical cylinder to an opening that is substantially similar to the outer shape of the container, for example, a substantially cylindrical opening or a substantially elliptical cylindrical opening. The diameter is expanded. The swelling / opening of the cylindrical label L by the suction device 25 ends when the expansion of the cylindrical label L by the label locking claw 31 of the label mounting device 3 is started.
[0024]
Note that, for example, the upper part of the cylindrical label L where the label locking claw 31 of the label mounting device 3 is not inserted has substantially the same original size. Further, when the suction of the tubular label L is stopped, the suction device 25 returns to the original position.
[0025]
At the same time as the diameter of the cylindrical label L is expanded, the lower label holding body 5 moves laterally to the cylindrical label L having an opening which is expanded in a substantially cylindrical shape so that the lower end of the cylindrical label L is moved outward. The label L is gripped to prevent the tubular label L from dropping off the label locking claw 31. The cylindrical container B is lifted from below by the elevating device 4 with respect to the cylindrical label L, and is inserted into the opening of the enlarged cylindrical label L via the label engaging claw 31 of the label mounting device 3. Thus, a cylindrical container B having the cylindrical label L mounted on the outer peripheral surface is obtained.
[0026]
Thereafter, the cylindrical container B on which the cylindrical label L is mounted is opened from the label presser 5, and the cylindrical label L is gripped by the upper label presser 6 from the outside of the cylindrical label L. The container B and the label presser 6 and the elevating device 4 are moved up in synchronization with each other, and the label engaging claw 31 of the label mounting device 3 is pulled out from the inside of the cylindrical label L. The label L is attached.
[0027]
The cylindrical container B to which the cylindrical label L is attached is sent out to a predetermined position by the elevating device 4 and the unloading device (not shown) while the label presser 6 is opened.
[0028]
FIGS. 2 and 3 show a cylindrical label mounting apparatus 3 according to the present invention, in which a first through hole 321 through which a cylindrical container B passes is formed at the center and a substrate 32 having the same. At least four guides 34 are fixed on the substrate 32 at equal intervals in the circumferential direction of the first through-hole 321, and a second through-hole 331 matching the first through-hole 321 is formed. A cam groove 35 is bored in the radial direction around the second through hole 331, and is rotatably formed above the substrate 32. A movable arm 36 having a roller follower 37 (not shown) formed on the back surface to be fitted in the cam groove 35 and having an upwardly directed label locking claw 31 provided at an end thereof; An electric motor 38, preferably a servo electric motor, is attached to the disk 33. It is equipped with a door.
[0029]
Then, the disk 33 is rotated by the driving of the electric motor 38 provided in the disk 33. With this rotation, the roller follower 37 fitted in the cam groove 35 of the disk body 33 operates so as to follow the inside of the cam groove 35 to move the moving arm 36 in a linear direction, and the label of the end of the moving arm 36 is locked. The claw 31 is changed from a small diameter in a closed (or reduced diameter) state to a large diameter in an opened (or enlarged diameter) state, and is inserted into the label locking claw 31 so as to be fitted into the label locking claw 31 so as to have an opening that bulges into a substantially elliptical cylinder. Is enlarged to a substantially cylindrical opening, and the cylindrical container B is pushed upward through the through holes 321 and 331 so that the cylindrical label L in the expanded state is placed on the outer peripheral surface of the cylindrical container B. It is made to be covered.
[0030]
In the figure, reference numeral 5 denotes a lower label presser, which is located outside the label locking claw 31 and is moved in the lateral direction at the same time as the cylindrical label L is expanded to have a substantially cylindrical shape. Of the lower end of the cylindrical label L to prevent the cylindrical label L from dropping off from the label locking claw 31.
[0031]
In the figure, reference numeral 6 denotes an upper label presser, which is located above and outward of the label locking claw 31 and simultaneously moves in the horizontal direction when the label presser 5 is opened from the cylindrical container B. By gripping the outside of the upper end of the cylindrical label L, it is complemented that the cylindrical label L is pulled out from the label locking claw 31 and is mounted on the label mounting portion of the cylindrical container B.
[0032]
In addition, the moving operation of the moving arm and the label locking claw or the label locking claw are provided so that the opening shape of the cylindrical label L is similar to the outer shape of the container according to the outer shape of the container. The size, shape, position, and number of the moving arms, and the disk 33 itself are adjusted and changed.
[0033]
In the figure, reference numeral 4 denotes an elevating device for elevating and moving the cylindrical container B upward and downward.
[0034]
A method of mounting the cylindrical stretch label L for packaging on the cylindrical container B by the cylindrical label mounting apparatus 3 configured as described above will be described with reference to FIGS.
[0035]
First, the peripheral speed of a flat long tube T formed from a synthetic resin film and wound on a roll-shaped body (not shown) and having folds on both side edges can be controlled through a support device 1 such as a rubber roller. While being intermittently fed by the feed roller 23, it passes through the auxiliary opening device 21 of the opening device 2 so as to expand the primary diameter to separate the fold portions and the uneven flat portions on both side edges, and to set a predetermined position of the elongated tube T. The sheet is cut into a predetermined length by the cutter 241 of the cutting device 24 to form a flat tubular label L. The flat cylindrical label L is sucked by the suction cups 251 of the pair of suction devices 25, and then, the cylindrical label L formed in a predetermined shape is sucked and held by the suction cups 251 of the suction device 25, and then the suction device An air cylinder or a hydraulic cylinder, or a servo motor (not shown) provided in 25 is driven to move in a separating direction, so that a cylindrical label L having free upper and lower edges is required, and A substantially elliptic cylindrical opening that swells into a sufficient opening or swells into an arbitrary opening, for example, an opening whose long side (flat side) is about twice as large as a short side (side in a direction perpendicular to the flat side). Formed on a cylindrical label L having the same.
[0036]
In addition, as shown by the solid line in FIG. 1, the suction device 25 cuts the long tube T with a cutter 241 of the cutting device 24 at a position separated by a predetermined distance from the end of the separator 216, and forms a cylindrical label L. As shown by the one-point hatched line in FIG. 1, the elongate tube T is lifted to a position near the feeding roller 23 to adsorb the long tube T and the separator 216 provided below the auxiliary opening device 21. The elongated tube T can be cut while being held.
[0037]
Then, the cylindrical labels L held in the swelling / opening state by the suction device 25 are held in the swelling / opening state by the suction device 25 in the circumferential direction of the through hole 321 of the substrate 32, respectively. An upwardly-facing label provided in a closed (or reduced-diameter) state at an end of a moving arm 36 which is movably mounted in a linear direction via a slider 341 on at least four guide bodies 34 fixed at intervals. It is inserted and supplied to the locking claw 31.
[0038]
Subsequently, the electric motor 38 is driven while the swelling / opening state of the cylindrical label L is continued by the suction device 25, and the disc body 33 communicated with the electric motor 38 via the gear and the boss (not shown) is removed. By rotating the roller follower 37, the roller follower 37 fitted in the cam groove 35 formed in the disk body 33 in the radial direction operates so as to follow the cam groove 35 and communicates with the roller follower 37. The moving arm 36 is moved linearly along the guide body 34 via the slider 341 to bring the cylindrical label L inserted into the upwardly-facing label locking claw 31 of the moving arm 36 into an expanded state.
[0039]
That is, the rotational movement of the disk 33 is changed to the linear movement of the moving arm 36 by the cam groove 35 and the roller follower 37, and as a result, the label locking claws 31 linearly move the guide 34 toward the corner of the substrate 32. And the label locking claw 31 changes from the small diameter in the closed (or reduced diameter) state to the large diameter in the opened (or expanded) state, and the substantially elliptical cylindrical opening fitted into the label locking claw 31. Is increased in diameter to a substantially cylindrical shape that matches the outer shape of the cylindrical container B.
[0040]
In addition, the cylindrical label L, for example, the upper part where the label locking claw 31 of the label mounting device 3 is not inserted has substantially the same original size. Further, when the suction of the tubular label L is stopped, the suction device 25 returns to the original position.
[0041]
At the same time as the diameter of the cylindrical label L is expanded, the lower label holding body 5 moves laterally to the cylindrical label L having an opening which is expanded in a substantially cylindrical shape so that the lower end of the cylindrical label L is moved outward. The label L is gripped to prevent the tubular label L from dropping off the label locking claw 31. The cylindrical label L is fed in by the carry-in device 7 and later passed through the container transfer machine 9 shown in FIG. 6 and placed on the container mounting table 441 provided on the ball screw 44 of the elevating device 4. Of the container B is pushed upward through the through holes 321 and 331 by driving the ball screw 44 of the lifting / lowering device 4 so that the cylindrical label L in an expanded state is placed on the label mounting portion on the outer peripheral surface of the cylindrical container B. To wear.
[0042]
Thereafter, the label presser 5 is opened, and at the same time, the upper label presser 6 that has been lowered when the cylindrical label L is inserted and supplied into the upward label locking pawl 31 is moved in the lateral direction. The label holding body 6 holds the vicinity of the upper end of the cylindrical label L mounted on the cylindrical container B.
[0043]
Subsequently, with the label holding member 6 holding the vicinity of the upper end of the cylindrical label L, the label holding member 6 and the lifting / lowering device 4 are raised together in synchronization with the cylindrical label L, and the cylindrical label L and the cylindrical label L are raised. The label locking claw 31 interposed between the container and the container B is pulled out, and is mounted on the label mounting portion of the cylindrical container B with the diameter reduced by the elastic restoring force of the cylindrical label L.
[0044]
The cylindrical container B to which the cylindrical label L is attached is opened by the label presser 6 and lowered by the elevating device 4, and is then sent out to a predetermined position by the unloading device 8 via the container transfer machine 9.
[0045]
Here, the container B to which the cylindrical label L is not attached is sent from the collecting site by a conveyor-like carrying-in device 7 made of synthetic resin or stainless steel, and the container B sent on the carrying-in device 7. Is temporarily stopped by a stopper 95 installed at a predetermined position, and then transferred from the loading device 7 to the container mounting table 441 of the lifting device 4 by the container transfer device 9.
[0046]
Further, the container B to which the predetermined cylindrical label L is attached is transferred from the container mounting table 441 of the elevating device 4 by a container transfer machine 9 at the elevating position of the container B, in the form of a conveyor made of synthetic resin or stainless steel. The container B on the unloading device 8 is transferred to a predetermined position.
[0047]
The container transfer machine 9 is an elevating device that is disposed between the carry-in device 7 that carries in the container B to which the tubular label L is not attached and the carry-out device 8 that takes out the container B to which the tubular label L is attached. 4, the containers B to which the cylindrical labels L are not attached are laterally moved (transferred) from the loading device 7 to the elevating device 4, and the containers B to which the cylindrical labels L are attached are moved to the elevating device 4. From the outside to the unloading device 8, and a pair of two plate-like sandwiching bodies 91 having a role of sandwiching and guiding are provided from both sides of the body of the container B at the same time, with a gap therebetween. It comprises a set (an upper set is omitted), a ball screw 92 and a servo motor 93 provided on the set via members, and a stopper 95 for temporarily stopping the container B. Reference numerals 94 and 96 denote an air cylinder for moving the two sets of plate-like sandwiching members 91 toward the body of the container B and an air cylinder for moving the stopper 95 in and out.
[0048]
The container transfer device 9 is configured such that the rotation of the servomotor 93 and the driving of the ball screw 92 cause the plate-shaped holding member 91 provided on the ball screw 92 to slide, and move the container B sandwiched between the plate-shaped holding members 91 by a predetermined distance. The horizontal movement (transfer) can be performed only by the encoder, and the distance of the lateral movement (transfer) can be controlled by an encoder attached to the plate-shaped sandwiching body 91 to receive the number of pulses and control means for controlling the number of pulses. It can be changed and adjusted as a center.
[0049]
Then, the container B carried in by the carrying-in device 7 is temporarily stopped at a predetermined position by a stopper 95, and the body of the container B is sandwiched from both sides by two sets of plate-like sandwiching bodies 91. The container B is moved laterally (transferred) onto the container mounting table 441 of the elevating device 4 by the movement and the driving of the ball screw 92, and the container B is lifted by the elevating device 4 using the two sets of plate-like sandwiching bodies 91 as guides. The tubular label L is mounted.
[0050]
After that, the container B to which the cylindrical label L is attached is lowered on the container mounting table 441 of the elevating device 4 using the two sets of the plate-like holding bodies 91 as a guide, and is sandwiched by the two sets of the plate-like holding bodies 91. It is placed in a state. The loaded container B is laterally moved (transferred) from the elevating device 4 to the unloading device 8 by the rotation of the servo motor 93 and the driving of the ball screw 92 while being sandwiched by the two sets of plate-shaped sandwiching members 91. When the lateral movement (transfer) is completed, the two sets of plate-like sandwiching bodies 91 return to their original positions by the rotation of the servo motor 93 and the driving of the ball screw 92. Subsequently, the above operation is repeatedly performed.
[0051]
Here, when the container B is changed to the container B having a larger diameter than the container B having a smaller diameter, as shown in the upper part of FIG. In other words, the number of pulses for the moving distance S is adjusted to the container B having a large diameter. On the other hand, when the container B is changed to the container B having a smaller diameter, as shown in the lower part of FIG. Then, the number of pulses corresponding to the movement distance s is adjusted to the container B having a small diameter.
[0052]
Thereby, even when the size and shape of the container B are changed, it is not necessary to change the position of the stopper according to the size and shape of the container, only by changing the setting of the number of pulses corresponding to the moving distance. It can be installed at a fixed position.
[0053]
As described above, according to the packaging tubular label mounting device of the present invention, a guide body is provided at equal intervals around a first through-hole on a substrate having a first through-hole through which a container passes in the center. And a rotatable disk body having a second through-hole matching the first through-hole and a cam groove formed therein, the disk body being rotatably provided to the guide body, A moving arm having a follower formed thereon and an upwardly directed label locking claw provided at an end thereof is mounted so as to be movable in a linear direction, and a motor is provided on the disk, and the disk is rotated by driving the motor to rotate the disk. The roller follower fitted in the cam groove of the body operates to move the moving arm in the linear direction, and the label locking claw of the moving arm is fitted to the label locking claw from the small diameter in the closed state to the large diameter in the opened state. The inserted cylindrical label is expanded and the container is Since the cylindrical label in the expanded state is covered on the outer peripheral surface of the container by pushing upward through the through-hole and being pushed upward, the label locking claw is set to a small closed (reduced diameter) state. Then, the label locking claw is supplied and fitted with a cylindrical label which is expanded and opened to a substantially elliptical cylindrical shape or an approximate shape thereof by a swelling means such as an opening means (apparatus) or a suction device. Each of the cylindrical labels can be opened outward in a state where the cylindrical labels are substantially uniformly expanded at a plurality of positions of the cylindrical label so that the cylindrical label is covered with the container.
[0054]
That is, a cylindrical label having an opening which is necessary and sufficiently swelled by an opening means (apparatus) or a swelling means such as a suction device, or an opening which is swelled in a substantially elliptical cylindrical shape matches the outer shape of the container. It can be formed in a cylindrical label having an opening.
[0055]
In addition, it is a matter of course that the cylindrical label is formed into a cylindrical label having an opening whose diameter is enlarged in a cylindrical shape so that the outer shape matches the cylindrical container. In order that the opening shape of the container may be similar to the outer shape of the container, the moving operation of the moving arm may be operated by synchronizing a plurality of them, or each may be operated independently to deal with the outer shape of the container, By adjusting / changing the dimensions / shape, position, number of the moving claws or the moving arms provided with the label pawls, and even the disc itself, the outer shape of the cylindrical label can be changed. It can also be formed in a tubular label having an opening that matches a rectangular or rectangular container.
[0056]
Furthermore, it is applied to a stretch label which is flat and has an inner diameter slightly smaller than the outer diameter of the container, and this label is necessary and sufficiently swelled or arbitrarily swelled by a label opening device in the previous step. The label is then formed into an opening and then applied to the cylindrical label mounting apparatus of the present invention to form a cylindrical label with an opening that is enlarged to match the outer shape of the container, and is then covered with the container. The label can be shrunk using the self-shrinkage property of the label and attached to the container.
[0057]
Alternatively, the present invention is applied to a flat, shrink label having an inner diameter slightly larger than the outer diameter of the container, and forming the label into an opening having an enlarged diameter so as to conform to the outer shape of the container, and covering the container with the label. The label may be shrunk using heat shrinkage by a heating means in a later step, and then attached to the container.
[0058]
Moreover, in the packaging tubular label mounting apparatus described above, by providing a label presser that presses the tubular label fitted on the label locking claw and the tubular label mounted on the outer surface of the container from the outer surface. When the container is pushed up by the elevating device onto the cylindrical label inserted into the label locking claw, and the cylindrical label is mounted on the outer surface of the container, or when the cylindrical label is mounted on the container, the label locking claw is used. The cylindrical label can be held down by the label presser when removing the container, and unevenness or waving of the cylindrical label may occur when the cylindrical label is placed on the outer surface of the container or when the label locking claw is removed from the container. This is preferable because the cylindrical label is beautifully mounted on the outer surface of the container.
[0059]
However, when a cylindrical shrink label having an inner diameter slightly larger than the outer diameter of the container is used for the cylindrical label, or when the cylindrical label is attached to the label locking claw, it is difficult to remove the label. When the nail is pulled out, if a device such as a non-slip or a small protrusion that can easily enter and exit is provided, it is not always necessary to provide a label presser.
[0060]
In addition, by using a servo motor as a motor for rotating the disc body that moves a moving arm provided with a label locking claw in a linear direction by operating a roller follower fitted in the cam groove of the disc body, Can be adjusted, so that the operation of the label locking claw provided on the moving arm can be controlled, which is suitable. However, an inverter motor or a general-purpose motor may be used depending on the container to which the tubular label is attached.
[0061]
【The invention's effect】
According to the packaging tubular label mounting device of the present invention, the tubular label supplied by label supply means such as opening means (apparatus) or a swelling means such as a suction device in a preceding process of the mounting device is used. Even if the supply timing is slightly deviated, it is possible to reliably supply and insert the label into the small-diameter label locking claw in the closed (reduced diameter) state.
[0062]
Moreover, when the cylindrical label is put on the outer surface of the container or when the label locking claw is pulled out from the container, unevenness and waving of the cylindrical label can be prevented, and the cylindrical label is beautifully placed on the outer surface of the container. It is suitable to be mounted.
[0063]
In addition, with the change of the shape of the container to which the cylindrical label is mounted, the work of replacing the label locking claw, the disc body, and the like can be easily performed, so that the working efficiency is improved and leads to the mounting of good quality. .
[0064]
Further, it is easy to grasp the movement from the small diameter (large diameter) of the closed (or opened) state of the label locking claw to the large diameter (small diameter) of the opened (or closed) state, and the diameter of the cylindrical label for packaging is increased. Needless to say, the work is also suitable for the maintenance work of the cylindrical label mounting device.
[0065]
Furthermore, a flat stretch label having an inner diameter slightly smaller than the outer diameter of the container can of course be applied to a flat shrink label having an inner diameter slightly larger than the outer diameter of the container.
[0066]
Further, by attaching the opening device provided with a suction device with a suction cup to the label mounting device of the present invention, the cut and formed cylindrical label is sucked and held by the suction device to keep the swelling / opening state. While expanding the label locking claw of the label mounting device, the diameter can be expanded to an opening almost similar to the outer shape of the container, so that the cylindrical label whose both ends are free can be expanded. The diameter can be expanded to a predetermined opening without causing a phenomenon such as falling down during opening.
