Description

Technical Field

[0001] The present invention relates to an adhesive tape application device. The adhesive tape can be a single-sided adhesive tape with an adhesive material applied only to one side serving as the application surface, or a double-sided tape with the adhesive material applied to both the front and back surfaces as well as the application surface. Furthermore, among adhesive tapes, there can be a continuous "continuous tape" in which a base material and an adhesive layer provided on one or both sides thereof are integrally formed in a strip shape and continuously without interruption. Additionally, there can be a discontinuous state in which single-sided tapes and double-sided tapes are appropriately cut, and there can be a "half-cut single-sided tape" or a "half-cut double-sided tape" that is continuously supported on a release liner before application. The application device according to the present invention is a device that transfers and applies a "continuous tape" or a "half-cut single-sided tape" or a "half-cut double-sided tape" to an object to be applied.

Background Art

[0002] There are various scenarios where application is required. There are a method of applying an adhesive and adhering, and a method of using an adhesive tape in which an adhesive material is included on one or both sides of a base material and applying the adhesive tape. In the former case, the curing process of the adhesive is often required. In the latter case, the curing process is often unnecessary, and it is often advantageous to use an adhesive tape when applying one object to be applied to another object to be applied.

[0003] The present invention is an invention related to an application device that applies an adhesive tape to an application location of an object to be applied. A general adhesive tape in the prior art has an adhesive layer provided on one or both sides of a base material layer, and is wound in a roll shape while being supported by a release liner before application. If a release agent is applied to one or both sides of the release liner, the release liner can be a single layer, and it can be wound in a roll shape from the inside in order. In the general market, it is provided in such a rolled state. The adhesive tape is fed out by the length required for pasting, positioned by pasting it on the object to be pasted, and then the release liner is peeled off to paste the object to be pasted.

[0004] Here, considering the industrial use of the adhesive tape, if the adhesive tape is a "continuous tape" that is continuously integrated in the length direction, a cutting process and a release liner peeling process are required, and these are mechanically controlled.

[0005] If the adhesive tape is a "half-cut single-sided tape" or a "half-cut double-sided tape", which is discontinuously cut in the length direction and the single-sided tape or double-sided tape is appropriately cut into a discontinuous state and is continuously supported on the release liner before pasting, the cutting process is not required, and only the release liner peeling process is sufficient, and this is mechanically controlled.

[0006] The above-described continuous tape pasting device is well-known in the prior art, so the description here is omitted. Next, a "half-cut double-sided tape" is known in the prior art. For example, Japanese Patent Application Laid-Open No. 2016-008262 of Patent Document 1 is known. As shown in FIG. 16, the half-cut double-sided tape is in a strip shape in which the double-sided tape is appropriately cut, and the surface is supported by the release paper before pasting. That is, the double-sided tape portion is cut into a large number in its width direction to form a strip shape, and it is a double-sided tape held on the release liner surface before pasting. For a half-cut double-sided tape, since it is already cut into an appropriate length strip shape from the beginning, it can be directly pasted on the object to be pasted or the object to be pasted while peeling the release paper from the release liner, and there is no need to cut, so it is convenient for automation using a double-sided tape. Also, for a half-cut double-sided tape, since the release liner peeling operation is performed simultaneously with the operation of pasting the double-sided tape on the object to be pasted or the object to be pasted, the release liner recovery operation is also easy. Due to such characteristics, the half-cut double-sided tape is particularly suitable for industrial applications and is expected to become more popular in the future.

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-008262 [Disclosure of the Invention] [Problems to be Solved by the Invention]

[0008] In the prior art, continuous tape pasting devices, half-cut single-sided tape or half-cut double-sided tape pasting devices in the prior art are pasting devices for pasting on a predetermined position of a predetermined object. In particular, there are few small-sized pasting devices with a simple structure and easy handling.

[0009] In view of the above problems, the present invention is a pasting device for pasting a continuous tape, a half-cut single-sided tape or a half-cut double-sided tape on a predetermined position of a predetermined object, and aims to provide a pasting device that can be miniaturized and can handle high-speed pasting processing. [Means for Solving the Problems]

[0010] In order to solve the above problems, the present invention has the following configuration. The components described below can be adopted in any combination as much as possible. It should also be understood that the aspects or technical features of the present invention are not limited to those described below, but are recognized based on the inventive concept described in the entire specification and drawings or grasped by those skilled in the art from those descriptions.

[0011] The sticking device for an adhesive tape according to the present invention is a sticking device that transfers and sticks the adhesive tape of the adhesive tape with a release liner to a predetermined position of an object to be stuck while peeling the adhesive tape from the release liner, and includes a roll body mounting portion that rotatably supports the roll-shaped adhesive tape with a release liner, a sticking transfer pressure portion through which the adhesive tape with a release liner fed out from the roll body mounting portion passes, a release liner recovery portion that winds up and recovers the release liner that has passed through the sticking transfer pressure portion in a roll shape, a support mechanism that supports the sticking transfer pressure portion, and a gear mechanism that interlocks the rotation of the roll body mounting portion and the rotation of the release liner recovery portion and enables the rotatable directions of the roll body mounting portion and the release liner recovery portion only in a predetermined direction. With the above configuration, a basic structure of a sufficiently miniaturized sticking device can be provided. It is possible to surely control the rotatable directions of the roll body mounting portion and the release liner recovery portion, which may cause problems when sticking by high-speed processing.

[0012] In the basic configuration of the sticking device for an adhesive tape according to the present invention described above, the roll body mounting portion includes a feeding rotary disk portion serving as a base, a roll body rotary shaft erected on the feeding rotary disk portion, and a roll body holder that rotatably supports a roll-shaped adhesive tape with a release liner around the roll body rotary shaft. The release liner recovery portion includes a winding rotary disk portion serving as a base, a release liner rotary shaft erected on the winding rotary disk portion, and a release liner holder that rotatably supports a roll-shaped release liner around the release liner rotary shaft. The gear mechanism preferably has a structure in which a side gear of the feeding rotary disk portion of the roll body mounting portion and a side gear of the winding rotary disk portion of the release liner recovery portion are in contact with each other and engaged. With the above configuration, it is possible to synchronize the feeding of the same amount and the winding of the same amount between the feeding rotary disk portion of the roll body mounting portion and the winding rotary disk portion of the release liner recovery portion.

[0013] Next, in the basic configuration of the above-described adhesive tape sticking device, the trajectory of the adhesive tape with a release liner fed from the roll body mounting portion to the sticking and pressing portion, and the trajectory of the release liner wound from the sticking and pressing portion to the release liner recovery portion are acute angles with the sticking and pressing portion as the vertex, the feeding position of the feeding rotary disk portion of the roll body mounting portion is a position facing the release liner recovery portion, and the winding position of the winding rotary disk portion of the release liner recovery portion can be a position not facing the roll body mounting portion. Here, by setting the feeding rotation direction of the feeding rotary disk portion of the roll body mounting portion and the winding rotation direction of the winding rotary disk portion of the release liner recovery portion to be opposite to each other, the above-described arrangement regarding the feeding position and the winding position becomes possible. With the above configuration, it becomes possible to arrange the feeding trajectory and the winding trajectory relatively close to each other at the initial attachment of the adhesive tape, and the sticking device can be miniaturized.

[0014] For example, in a roll-shaped adhesive tape with a release liner having the maximum diameter in an unused state attached to the roll body mounting portion, the trajectory of the adhesive tape and the trajectory of the release liner can be parallel without contact, or an acute angle of 30 degrees or less with the sticking and pressing portion as the vertex, and it is also possible to make it an acute angle of 15 degrees or less. The roll body mounting portion with the unused adhesive tape attached has the maximum diameter, but if the feeding position of the half-cut double-sided tape with a release liner and the winding position of the release liner of the release liner recovery portion are devised as described above, the two will not interfere with each other, and the trajectories of the two can be made relatively close to each other, and the sticking device can be miniaturized.

[0015] In the above configuration, the sticking and pressing portion can be provided with a non-rotating body supported non-rotatably by the support mechanism, and the surface through which the adhesive tape with a release liner passes can be a smooth curved surface, or the sticking and pressing portion can be provided with a rotating body supported rotatably by the support mechanism. If the sticking and pressing part is provided with a rotating body, the sticking movement will be smooth, but it is necessary to incorporate a rotation mechanism and continue to control it. Even when the sticking and pressing part is supported by the support mechanism so as not to rotate, as long as the surface is smooth, it is possible to transfer the adhesive tape while smoothly passing the adhesive tape with a release liner, and in this case, there is an advantage that the structure of the support mechanism becomes simple.

[0016] Next, the inventor of the present invention also invented a method of parallelizing the feeding and winding of the adhesive tape in the configuration of the adhesive tape sticking device of the present invention. That is, the roll body mounting part and the release liner recovery part are set as one set, and a plurality of sets of the sets of the roll body mounting part and the release liner recovery part are provided in the axial direction of each of the roll body rotation axis and the release liner rotation axis. According to this configuration, the adhesive tape can be stuck simultaneously in the number of sets of the plurality of sets.

[0017] In addition, the inventor of the present invention also invented a method of parallelizing the sticking and pressing part in the structure of parallelizing the feeding and winding of the adhesive tape as described above. That is, the roll body mounting part, the sticking and pressing part, and the release liner recovery part are set as one set, and a plurality of sets of the sets of the roll body mounting part, the sticking and pressing part, and the release liner recovery part are provided in the axial direction of each of the roll body rotation axis and the release liner rotation axis. According to this configuration, the adhesive tape can be stuck simultaneously in the number of sets of the plurality of sets.

[0018] In addition, in the above configuration, it is also possible to provide a configuration in which the sticking and pressing part is provided with a suspension movement mechanism for the object to be stuck. If the sticking and pressing part is provided with a suspension movement mechanism for the object to be stuck, that is, a mechanism for controlling the height with respect to the sticking surface, even if the object to be stuck is a three-dimensional object and the surface is smooth to some extent, the adhesive tape can be stuck to the three-dimensional object. In addition, as described above, in the case of a configuration in which a plurality of sets of a roll body mounting portion, an adhesive transfer pressure portion, and a release liner recovery portion are provided in the axial direction, each adhesive transfer pressure portion includes a suspension movement mechanism for the object to be adhered, and the suspension movement mechanisms of these adhesive transfer pressure portions can be independent of each other. Here, when the adhesive tape is attached all at once over a plurality of sheets, even if the surface of the object to be attached has fine irregularities, if the suspension movement mechanisms of the respective adhesive transfer pressure portions are independent of each other, they can move up and down independently along the fine irregularities on the surface of the object to be attached, and the adhesive tape can be neatly applied.

[0019] Furthermore, in the above configuration, a configuration including a steering movement mechanism for changing the support angle in the horizontal plane by the support mechanism in the adhesive transfer pressure portion is also possible. If the adhesive transfer pressure portion is provided with a steering movement mechanism, that is, a mechanism for changing the direction in the horizontal direction on the adhesive surface, not only linear attachment of the adhesive tape but also curved attachment and the like to the object to be attached become possible.

[0020] Next, in the basic configuration of the adhesive tape attaching device according to the present invention described above, a switch mechanism for switching between a rotatable state and a non-rotatable state of the gear mechanism is provided, and the switch mechanism includes a stop gear that meshes with a side gear of the feeding rotary disk portion of the roll body mounting portion, and can control the contact state of the stop gear with the side gear, and can control the contact meshing state and the separated state of the side gear of the feeding rotary disk portion of the roll body mounting portion. With the above configuration, the operation (on / off) of the attaching device can be adjusted, and it is possible to prevent the half-cut double-sided tape from being inadvertently attached to a location other than the predetermined one.

[0021] Here, in a state where the adhesive transfer pressure portion accesses the object to be attached, it is preferable that the switch mechanism is arranged at a position higher than the roll body rotation axis of the roll body mounting portion. In a structure where the side gear of the roll body mounting portion meshes with the side gear of the pay-out rotating disk portion, and further in the arrangement of the switch mechanism that meshes with the side gear of the pay-out rotating disk portion of the roll body mounting portion, it can be arranged in a relatively spacious space, enabling miniaturization of the pasting device. Also, if the switch is near the upper surface, there is an advantage that the control of the switch mechanism becomes easier.

[0022] Next, as an auxiliary member, it is also preferable to include a rotation adjuster that is attached to the roll body rotation shaft of the roll body mounting portion or the peeling liner rotation shaft of the peeling liner recovery portion and is rotated from the outside to adjust the deviation of the rotation angle. With the above auxiliary member, when there are minute relaxations or the like in the attachment posture of the half-cut double-sided tape with a peeling liner and the peeling liner, the attachment posture of the half-cut double-sided tape with a peeling liner and the peeling liner can be adjusted well by adjusting the deviation of the rotation angle.

[0023] Note that as the adhesive tape of the adhesive tape with a peeling liner handled by the adhesive tape pasting device according to the present invention, there is a single-sided adhesive tape which is a continuous tape and has an adhesive material applied only to one side which becomes the pasting surface. It is a commonly used adhesive tape. For example, there are vinyl tapes, medical tapes, and medicinal tapes including plasters. Furthermore, as the adhesive tape of the adhesive tape with a peeling liner handled by the adhesive tape pasting device according to the present invention, there is a half-cut single-sided adhesive tape which is in a state of being half-cut into a number of small pieces. When the adhesive tape is transferred and pasted to a predetermined location of an object to be pasted while being peeled from the peeling liner, there is the half-cut single-sided tape which is in a state of being half-cut into a number of small pieces at the pasting mark. It is a tape that is easy to paste on a curved surface. This half-cut single-sided tape is not common and is considered to have few disclosures as prior art. Furthermore, as the adhesive tape of the adhesive tape with a release liner handled by the adhesive tape sticking device according to the present invention, it is a half-cut double-sided tape that has been half-cut into a number of small pieces. When the adhesive tape is transferred and stuck to a predetermined position of an object to be stuck while being peeled off from the release liner, there is the half-cut double-sided tape that has been half-cut into a number of small pieces in the sticking mark. It is a tape used when sticking another object to an object to be stuck. This half-cut single-sided tape is not common, and it is considered that there are only a few disclosures such as the above-mentioned Patent Document 1 as the prior art.

[0024] The above-described adhesive tape sticking device according to the present invention can also be manually operated, and can be provided as an adhesive tape sticking device for manually sticking an adhesive tape to an object to be stuck. Also, the above-described adhesive tape sticking device according to the present invention can also be operated in a form that is driven by another mechanical device. That is, the sticking device can be attached to the tip of an automatic lifting device and driven by the automatic lifting device, and can be provided as an adhesive tape sticking device for sticking an adhesive tape to an object to be stuck while being driven by the automatic lifting device.

Effects of the Invention

[0025] According to the adhesive tape sticking device of the present invention, since either the roll body mounting portion or the release liner recovery portion, or both the roll body mounting portion and the release liner recovery portion are configured with a rotation mechanism, the feeding of the half-cut double-sided tape can be smoothly performed, so that it can cope with a high-speed sticking operation, and the posture of the half-cut double-sided tape is not distorted, and it can be accurately stuck.

Best Mode for Carrying Out the Invention

[0027] Hereinafter, a sticking tape sticking device according to the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to what is shown in the following examples. As Example 1, a basic configuration example of the sticking tape sticking device 100 of the present invention is shown. Note that it is a configuration example when one set consists of a roll body mounting part 110, a sticking and rolling pressure part 130, and a release liner recovery part 120. As Example 2, a basic configuration example of the sticking tape sticking device 100A of the present invention is shown. Note that it is a configuration example in which one set consists of a roll body mounting part 110, a sticking and rolling pressure part 130, and a release liner recovery part 120, and a plurality of sets of the roll body mounting part 110, the sticking and rolling pressure part 130, and the release liner recovery part 120 are provided in the axial direction of each of the roll body rotation axis and the release liner rotation axis.

Example 1

[0028] The sticking tape sticking device according to Example 1 of the present invention will be described. Example 1 is a configuration example when the sticking tape sticking device 100 is manually operated. In the following description, the feeding direction and the winding direction of the double-sided tape with a release liner and the processing release tape are referred to as the 'length direction', and the direction orthogonal to the length direction is referred to as the 'width direction'. Even in the case of a half-cut strip-shaped small piece, the direction along the length direction of the original tape is the length direction, and what corresponds to the width direction of the original tape is described as the width direction.

[0029] FIG. 1 is a diagram briefly showing the configuration of the adhesive tape sticking device 100 according to the present invention. In FIG. 1, centered on the front view, plan views, bottom views, left side views, and right side views are shown above, below, to the left, and to the right, and further below the bottom view, there is a perspective view of the bottom surface seen from an oblique direction. FIG. 2 is a diagram briefly showing the interior of the configuration of the adhesive tape sticking device 100 according to the present invention with the member corresponding to the cover removed from the housing 160. Note that it shows a state in which a roll of the adhesive tape 200 with a release liner is mounted. In FIG. 2 as well, centered on the front view, plan views, bottom views, left side views, and right side views are shown above, below, to the left, and to the right, and further below the bottom view, there is a perspective view of the bottom surface seen from an oblique direction. FIG. 3 is a diagram briefly showing the interior of the configuration of the adhesive tape sticking device 100 according to the present invention. Note that it shows a state in which the roll of the adhesive tape 200 with a release liner is not mounted. In FIG. 3 as well, centered on the front view, plan views, bottom views, left side views, and right side views are shown above, below, to the left, and to the right, and further below the bottom view, there is a perspective view of the bottom surface seen from an oblique direction.

[0030] As shown in FIGS. 1 to 3, the adhesive tape sticking device 100 of the present invention according to Example 1 has a configuration example including a roll body mounting portion 110, a release liner recovery portion 120, a sticking and rolling portion 130, a gear mechanism 140, a switch mechanism 150 for device operation, and a housing 160. Further, as an option, it has a configuration example including a rotation adjuster 170 for adjusting the deviation of the rotation angle. Note that, if necessary, the adhesive tape 200 with a release liner which is a sticking member, the surface adhesive tape 210, and the base release liner 220 are shown.

[0031] Note that the sizes and structures of the respective parts of the device are not limited. In particular, the arrangement positions of the roll body mounting part 110, the release liner recovery part 120, and the sticking and pressing part 130 housed in the housing 160 are just examples. Also, although the gear mechanism 140 is depicted in a simplified manner, it suffices as long as the rotations of the roll body mounting part 110 and the release liner recovery part 120 are interlocked with each other. Further, the width of the adhesive tape 200 with a release liner may be smaller than the width of the roll body mounting part 110 or the width of the release liner recovery part 120, and the ratio is not limited to that shown in the figure.

[0032] Hereinafter, the configuration of each part of the adhesive tape sticking device 100 will be described. The roll body mounting part 110 is a member that rotatably supports the roll-shaped adhesive tape 200 with a release liner, and is a device that supplies the adhesive tape 200 with a release liner to be conveyed in a predetermined posture. Although the structure of the roll body mounting part 110 itself is not limited, there can be various types depending on the shape and size of the roll body of the adhesive tape 200 with a release liner to be mounted.

[0033] In this configuration example, the roll body mounting part 110 includes a pay-out rotating disk part 111 and a roll body rotating shaft 112. The pay-out rotating disk part 111 is a disk body that serves as the base of the roll body mounting part 110. It rotatably houses the roll-shaped adhesive tape 200 with a release liner. The roll body rotating shaft 112 is a rotating shaft erected at the center of the pay-out rotating disk part 111. It rotatably supports the roll-shaped adhesive tape 200 with a release liner around the roll body rotating shaft 112. The roll-shaped adhesive tape 200 with a release liner has a structure that can be attached to and detached from the pay-out rotating disk part 111 and the roll body rotating shaft 112, enabling attachment, replacement, replenishment, and detachment of the adhesive tape 200 with a release liner to the roll body mounting part 110.

[0034] Note that, as will be described later, the gear mechanism 140 is incorporated so as to interlock between the roll body mounting portion 110 and the release liner recovery portion 120. A side gear 141 is provided on the pay-out rotating disk portion 111 of the roll body mounting portion 110. It has a structure in which it abuts and meshes with a side gear 142 on the side of the winding rotating disk portion 111 of the release liner recovery portion 120.

[0035] The release liner recovery portion 120 winds up and recovers the release liner 220 remaining after the surface adhesive tape 210 has been transferred and attached elsewhere through the sticking and pressing portion 130 in a roll shape. It winds up and recovers the release liner 220 by rotating like a so-called reel winding device. In this configuration example, the release liner recovery portion 120 includes a winding rotating disk portion 121, a release liner rotating shaft 122, and a fitting shape 123. The winding rotating disk portion 121 is a disk body that serves as the base of the release liner recovery portion 120. The release liner rotating shaft 122 is a rotating shaft erected at the center of the winding rotating disk portion 121. It supports the release liner around the release liner rotating shaft 122 in a roll shape so that it can be recovered.

[0036] Note that the side gear 141 on the pay-out rotating disk portion 111 of the roll body mounting portion 110 and the side gear 142 on the side of the winding rotating disk portion 111 of the release liner recovery portion 120 are in contact and mesh with each other. Here, the rotation of the roll body mounting portion 110 and the release liner recovery portion 120 is interlocked by the gear mechanism 140 to be described later, and the pay-out length of the adhesive tape 200 with the release liner of the roll body mounting portion 110 and the winding length of the release liner 220 of the release liner recovery portion 120 are made to match. Therefore, the adhesive tape 200 with the release liner fed out from the roll body mounting portion 110 does not accumulate and double up, and the winding length of the release liner 220 is not excessive to cause tensile strength and break the release liner 220.

[0037] The sticking and pressing part 130 is a member that supports the adhesive tape 200 with a release liner, which is fed out from the roll body mounting part 110, so that it passes along the outer surface. The sticking and pressing part 130 includes a rotating body 132 and a support mechanism 131 that rotatably supports the rotating body 132. In FIGS. 1 to 3, the members of the rotating body 132 and the support mechanism 131 are not shown in the sticking and pressing part 130, but will be shown and described in Example 2 described later. The rotating body 132 may be a small ring-shaped one and may be provided with a rotating shaft that serves as a shaft. The support mechanism 131 may be any mechanism that rotatably supports the rotating body 132. For example, the support mechanism 131 may be a bearing that rotatably supports the rotating shaft of the rotating body 132. While the sticking and pressing part 130 rotates and presses while being in contact with the object to be stuck, the adhesive tape 210 that has been half-cut into a number of small pieces is transferred and stuck to a predetermined position of the object to be stuck. If the surface of the portion to be stuck has a physical property that strongly adheres to the adhesive layer, the adhesive tape 210 peels off from the release liner 220 and is transferred at the same time as it is being stuck. The remaining release liner 220 is collected by the release liner collection part 120.

[0038] Here, the device in the trajectory of the adhesive tape 200 with a release liner stretched between the roll body mounting part 110, the sticking and pressing part 130, and the release liner collection part 120 will be described. As shown in FIG. 2, in this configuration example, the trajectory of the adhesive tape 200 with a release liner fed out from the roll body mounting part 110 to the sticking and pressing part 130 and the trajectory of the release liner 220 wound from the sticking and pressing part 130 to the release liner collection part 120 form an acute angle with the sticking and pressing part 130 as the vertex. The feeding position of the adhesive tape 200 with a release liner on the feeding rotating disk part 111 of the roll body mounting part 110 is a position on the side facing the release liner collection part 120, and the winding position of the winding rotating disk part 121 of the release liner collection part 120 is a position that does not face the roll body mounting part 110.

[0039] Furthermore, by setting the feeding rotation direction of the feeding rotating disk portion 111 of the roll body mounting portion 110 and the winding rotation direction of the winding rotating disk portion 121 of the peeling liner recovery portion 120 to be opposite to each other, the above-described arrangement for the feeding position and the winding position becomes possible. FIG. 4 shows an example of the feeding rotation direction of the feeding rotating disk portion 111 of the roll body mounting portion 110 and the winding rotation direction of the winding rotating disk portion 121 of the peeling liner recovery portion 120 inside the adhesive tape sticking device 100. As shown in FIG. 4, the feeding rotation direction of the feeding rotating disk portion 111 of the roll body mounting portion 110 is counterclockwise, while the winding rotation direction of the winding rotating disk portion 121 of the peeling liner recovery portion 120 is clockwise. It can be seen that the respective rotation directions are opposite. With the rotation directions as shown in FIG. 4, it is possible to relatively closely arrange the feeding trajectory and the winding trajectory of the half-cut double-sided tape 200 and to ensure that both trajectories are separated by a necessary interval and do not interfere with each other, enabling miniaturization of the sticking device. In FIG. 4, the switch mechanism 150 is pressed so that the half-cut double-sided tape 200 can be fed, and the feeding rotation of the feeding rotating disk portion 111 of the roll body mounting portion 110 is possible.

[0040] If the diameter of the feeding rotating disk portion 111 of the roll body mounting portion 110 is larger than the maximum diameter (i.e., the diameter in the unused state) of the adhesive tape 200 with a peeling liner, even if a roll-shaped adhesive tape 200 with a peeling liner having the maximum diameter in the unused state is attached to the roll body mounting portion 110, the feeding trajectory and the winding trajectory of the half-cut double-sided tape 200 do not interfere with each other. In this way, the trajectory of the roll-shaped adhesive tape 200 with a peeling liner having the maximum diameter in the unused state attached to the roll body mounting portion 110 and the trajectory of the peeling liner 220 can be parallel without contact, or can be at an acute angle larger than parallel. That is, it is an acute angle with the sticking and pressing portion as the apex, and for example, it can be an acute angle of 30 degrees or less or 15 degrees or less. In the internal space of the adhesive tape sticking device 100, the roll body mounting part 110, the release liner collecting part 120, and the sticking and pressing part 130 can be arranged with good space efficiency, and the whole device can be miniaturized.

[0041] The gear mechanism 140 is a mechanism that interlocks the rotation of the roll body mounting part 110 and the rotation of the release liner collecting part 120, and makes the rotatable directions of the roll body mounting part 110 and the release liner collecting part 120 possible only in a predetermined direction. In this example, a part of the gear mechanism 140 (referred to as the first gear 141) is provided on a part of the roll body mounting part 110, and a part of the gear mechanism 140 (referred to as the second gear 142) is provided on a part of the release liner collecting part, and the first gear 141 and the second gear 142 are in a meshed state. That is, when the first gear 141 rotates, the second gear 142 rotates with a rotation length corresponding to the rotation length of the first gear 141, and the two are accurately interlocked.

[0042] There can be many patterns of structures that can function as gears of the gear mechanism 140. Here, gears are provided on the side surfaces of two rotating bodies respectively, and the side surfaces of both are in contact with each other so that the rotational motion is interlocked, which is shown as spur gears. However, there can be many patterns of gears. Here, it is assumed that there is no electrical actuator such as a motor inside the adhesive tape sticking device 100, and the driving force is generated by the frictional force received by the sticking and pressing part 130 from the sticking target location as the rotational torque of the sticking and pressing part 130, and this rotational torque serves as the driving force. However, a configuration in which an electrical actuator such as a motor is incorporated in any one of or a combination of the roll body mounting part 110, the release liner collecting part 120, and the sticking and pressing part 130, and the actuator such as a motor applies a driving force is not excluded.

[0043] The switch mechanism 150 is a switch mechanism that switches between the rotatable state and the non-rotatable state of the gear mechanism 140. In this configuration example, the switch mechanism 150 is configured to include a stop gear 151 that meshes with the side gear 141 of the payout rotating disk portion 112 of the roll body mounting portion 110. The stop gear 151 can control the contact state with the side gear 141 of the payout rotating disk portion 112 of the roll body mounting portion 110 when the button of the switch mechanism 150 is pressed. That is, it can control the contact and meshing state and the separated state with respect to the side gear 141 of the payout rotating disk portion 111 of the roll body mounting portion 110. In the state of FIG. 2, the roll body mounting portion 110 is in contact and meshed with the side gear 141 of the payout rotating disk portion 111 by the switch mechanism 150 and is in a stopped state, while in the state of FIG. 4, the switch mechanism 150 is pressed and detached from the side gear 141 of the payout rotating disk portion 111 of the roll body mounting portion 110 to be in a rotatable state. Note that the structure and arrangement position of this switch mechanism 150 are not limited. In this configuration example, for example, in a state where the sticking and pressing portion 130 accesses the object to be stuck (that is, the use state of the adhesive tape sticking device 100), it is preferable that the switch mechanism 150 is arranged at a position higher than the roll body rotation shaft 110 of the roll body mounting portion 110. With this arrangement position, even in the use state of the adhesive tape sticking device 100, the switch mechanism 150 can be immediately operated to switch between the operating state and the stopped state of the adhesive tape sticking device 100.

[0044] The housing 160 is a housing that covers the entire adhesive tape sticking device 100. In this example, it has a base portion and a cover portion, and the cover portion can be removed. There are a plurality of openings, including an opening 161 that serves as the sticking surface of the rotating body 132 of the sticking and pressing portion 130, an opening 162 for the operation portion of the switch mechanism 150, and further, in this configuration example, an opening 163 for the access surface of the rotation adjuster 170 described later is provided. The sticking device 100 for an adhesive tape of the present invention is, for example, a device for sticking a half-cut double-sided tape that an operator holds by hand. Therefore, it is better for the sticking device 100 for an adhesive tape to be compact and easy to handle. When in use, the housing 160 covers so that there is no unnecessary access from the outside to the roll body mounting portion 110, the release liner collecting portion 120, the sticking and pressing portion 130, and the gear mechanism 140, which are internal members. Note that at least the opening 161 is provided so that a half-cut double-sided tape can be stuck, and the sticking surface of the rotating body 132 of the sticking and pressing portion 130 is exposed to the outside. Further, in this configuration example, since the switch mechanism 150 for operating the device is provided, another opening 162 is provided so that the operation portion of the switch mechanism 150 for operating the device appears on the surface.

[0045] The rotation adjuster 170 is an optional member, but it is an auxiliary tool that is attached to the roll body rotation shaft 111 of the roll body mounting portion 110 or the release liner rotation shaft 121 of the release liner collecting portion 120 and rotated from the outside to adjust the deviation of the rotation angle. Originally, due to the accurate interlocking by the gear mechanism 140, the rotation lengths of the roll body rotation shaft 111 of the roll body mounting portion 110 and the release liner rotation shaft 121 of the release liner collecting portion 120 should be the same. However, mechanical variations, elongation and contraction due to tensile strength and temperature changes overlap, and when doubling or tension increase of the adhesive tape 200 with a release liner is observed, the rotation adjuster 170 is used to adjust the deviation of the rotation angle. In this configuration example, a concave fitting shape 123 that fits with the rotation adjuster 170 is provided on the release liner rotation shaft 121 of the release liner collecting portion 120, and an opening 163 is provided to enable access to this fitting shape 123 from the outside. The rotation adjuster 170 is fitted to the fitting shape 123 from the outside through this opening 163 so that the release liner rotation shaft 121 of the release liner collecting portion 120 can be rotated.

[0046] The outline of the movement of the entire sticking device 100 for an adhesive tape of the present invention according to Example 1 will be described below. FIG. 5 is a diagram showing an outline of the flow of the movement of the entire adhesive tape sticking device 100 according to Example 1. First, as from the state of FIG. 3 to the state of FIG. 2, a roll-shaped adhesive tape 200 with a release liner is mounted on the roll body mounting portion 110, and the end portion of the release liner 220 is attached to the release liner recovery portion 120 via the sticking and pressing portion 130. Ordinarily, further, as shown from FIG. 2 to FIG. 1, the housing 160 is attached, but here, the description will be continued in the state of FIG. 2 where the housing 160 is not attached so that the internal operation can be easily understood.

[0047] As shown from FIG. 5(a) to FIG. 5(b), the sticking and pressing portion 130 of the adhesive tape sticking device 100 is operated to move along the sticking portion on the surface of the object to be stuck. At that time, the adhesive tape 200 with a release liner exposed on the surface of the sticking and pressing portion 130 rotates while coming into contact with the sticking portion on the surface of the object to be stuck.

[0048] As shown in FIG. 5(b), as the adhesive tape sticking device 100 moves, the adhesive tape 200 with a release liner is stuck to the sticking portion on the surface of the object to be stuck by its adhesive force and remains, leaving a sticking locus along its movement locus. As the adhesive tape sticking device 100 moves, the adhesive tape 200 with a release liner is fed out from the roll body mounting portion 110, and the release liner 220 is recovered by the release liner recovery portion 120. Since both are interlocked by the gear mechanism 140, the feeding length of the adhesive tape 200 with a release liner is balanced with the winding length of the release liner 220, so that the adhesive tape 200 with a release liner and the release liner 220 do not get doubled or excessive tension does not occur.

[0049] As the adhesive tape 200 with a release liner is fed out, the diameter of the roll body at the roll body mounting portion 110 decreases, and as the release liner 220 is wound up, the diameter of the roll body at the release liner recovery portion 120 increases. However, since the former feeding trajectory and the latter winding trajectory are parallel or at an acute angle, the trajectories of the two do not interfere with each other. The adhesive tape 210 can be actually attached smoothly, so that a high-speed attachment process can be performed on the object to which the adhesive tape 210 is to be attached.

[0050] Here, the adhesive tape 200 with a release liner used in the adhesive tape attaching device 100 of the present invention will be described. The adhesive tape 200 with a release liner is not particularly limited as long as it is a tape in which an adhesive tape having an adhesive layer is attached on a release agent of the release liner. For example, the adhesive tape may be a continuous "continuous tape" in which a base material and adhesive layers provided on one or both sides thereof are integrally formed in a strip shape without interruption. Further, there are also "half-cut single-sided tapes" and "half-cut double-sided tapes" in a discontinuous state in which single-sided tapes and double-sided tapes are appropriately cut and are continuously supported on the release liner before being attached and used.

[0051] FIG. 6 is a diagram showing examples of attachment traces of various adhesive tapes 210. FIG. 6(a) shows an attachment trace of a continuous "continuous tape" that is integrally formed in a strip shape without interruption. It simply shows how the adhesive tape 210 is attached linearly. FIG. 6(b) shows an example of an attachment trace of a half-cut double-sided tape 210 that is in a discontinuous state in which single-sided tapes and double-sided tapes are appropriately cut. In actuality, the half-cut double-sided tapes are strip-shaped fragments adjacent to each other, and the interval between the strip-shaped double-sided tape pieces is small. However, here, the interval is deliberately increased for easy understanding of the shape and attachment trace of each strip-shaped double-sided tape piece and is simply shown. Fig. 6(c) is a diagram briefly showing a state where a half-cut double-sided tape is attached along an arc-shaped curve on the surface of a planar object to be attached. In the attachment trace of the half-cut double-sided tape 210, it can be seen how a curve can be drawn. Although this is simply an example of an arc, it can be understood that an irregular curve can also be drawn. Fig. 6(d) is a diagram briefly showing a state where a half-cut double-sided tape is attached along a curved surface on the surface of a curved object to be attached. Thus, according to the tape attaching device 100 of the adhesive tape of the present invention, since a strip-shaped double-sided tape can draw an attachment trace along a curve or a curved surface, the half-cut double-sided tape 210 can be attached to the surfaces of various objects to be attached, and the usage of the double-sided tape is expanded. In this Fig. 6, only an example of the attachment trace is shown, and it will be understood that various attachment traces are possible. Note that Fig. 6 only shows the attachment trace to an object to be attached that is relatively close to a plane, but it will also be understood that even if the object to be attached is a three-dimensional object with a greater height difference, a target attachment process can be performed by adjusting the attachment condition to the three-dimensional surface.

[0052] The above is an outline of the overall movement when manually operating the tape attaching device 100 of the adhesive tape of the present invention according to Example 1.

[0053] Next, a configuration example is shown when the tape attaching device 100 of the adhesive tape is attached to the tip of the automatic lifting device 300 and automatically attached following the automatic lifting device 300. Also in this configuration example, the operation itself of the tape attaching device 100 of the present invention may be the same as described above. The difference is that the access of the tape attaching device 100 of the present invention to the object to be attached, that is, the positioning process in the horizontal plane and the height adjustment during attachment, are automatically processed by the automatic lifting device 300 instead of manually.

[0054] Fig. 7 is a diagram briefly showing a configuration example of the tape attaching device 100 incorporated in the automatic lifting device 300. As shown in Fig. 7, the adhesive tape applicator 100 is attached to the tip of the automatic lifting device 300. Although the adhesive tape applicator 100 has a different connection part 180 with the automatic lifting device 300, the other internal components of the adhesive tape applicator 100, namely the roll body mounting part 110, the release liner recovery part 120, the pasting and pressing part 130, the gear mechanism 140, the switch mechanism 150, the housing 160, and the rotation adjuster 170 (their internal components are not shown in Fig. 7), may have the same configuration as those shown in the first embodiment.

[0055] The connection part 180 with the automatic lifting device 300 is provided, for example, on a part of the housing 160. On the other hand, on the side of the automatic lifting device 300, a mounting part 310 is provided that can be connected to and detached from the connection part 180 of the adhesive tape applicator 100. As shown in Fig. 7, attach the adhesive tape applicator 100 to the mounting part 310 of the automatic lifting device 300 via the connection part 180.

[0056] The automatic lifting device 300 includes, but is not limited to, for example, a transport path 320 for transporting the object to be mounted along a predetermined trajectory, and there is a mechanism for the mounting part 310 to access by raising and lowering its height with respect to this transport path 320. There is also a structural example with only a height adjustment mechanism that simply moves up and down, or a structure with multiple joints like a robotic arm that combines horizontal and vertical movement. This automatic lifting device 300 is a mechanism for controlling the height of the rotating body 132 of the pasting and pressing part 130. In the pasting and pressing part 130, height control is performed to switch between the "contact height" at which the double-sided tape with a release liner that has been half-cut contacts the area to be pasted, and the "separation height" at which the adhesive tape 200 with a release liner is separated from the area to be pasted.

[0057] In Fig. 8, Fig. 8(a) shows an example where the pasting and pressing part 130 is lowered to the "contact height" position, and Fig. 8(b) shows an example where the pasting and pressing part 130 is raised to the "separation height" position. In the sticking stroke, during the period from "start of sticking" to "sticking period", the height of the rotating body 132 is maintained at the "contact height" by the height control mechanism. However, at the end of the "sticking period", that is, in the "end of sticking" process, the height of the rotating body 132 is lifted to the "separation height" by the height control mechanism. As shown in FIG. 9, when the height of the rotating body 132 is lifted to the "separation height" by the height control mechanism, the half-cut double-sided tape 210 transferred onto the object to be stuck remains as it is, but the release liner 220 rises and the two are separated.

[0058] In this way, the half-cut double-sided tape 200 itself consists of independent half-cut double-sided tape pieces, and after sticking, they are in an independent state on the surface of the sticking target location. At the sticking target location, if the half-cut double-sided tape 200 is stuck for a desired length and then the sticking device 100 of the adhesive tape is simply pulled up, each of the stuck half-cut double-sided tape pieces in an independent state will remain on the surface of the sticking target location as it is.

[0059] It is also possible to devise the elevation angle of the height control of the rotating body 132 by the height control mechanism. As described above, the height control mechanism performs sticking control to switch the height of the rotating body 132 between the "contact height" in contact with the sticking target location and the "separation height" separated from the sticking target location. Here, in the switching between the "contact height" and the "separation height", although the height control mechanism pulls up the rotating body 132 upward, there can be several pulling-up patterns.

[0060] What is shown in FIG. 9(a) is the first pattern of sticking control by the height control mechanism, and the change from the "contact height" to the "separation height" is a vertically upward pattern. This has already been described above. Next, what is shown in FIG. 9(b) is the second pattern of sticking control by the height control mechanism, and the change from the "contact height" to the "separation height" is obliquely upward in front of the stuck half-cut double-sided tape. It is so to speak a pulling-up operation in the forward direction. Since the half-cut double-sided tape with a release liner is originally cut into small pieces, if it is pulled diagonally upward in the front while leaving the half-cut double-sided tape with a release liner of the small piece already pasted at the pasting position, it is conceivable that the end of the half-cut double-sided tape with a release liner of the small piece at the boundary of the pasting position follows diagonally upward in the front. However, in reality, the friction with the object to be pasted is extremely small, and as shown in Fig. 9(b), it peels off from the object to be pasted and remains at the pasting position.

[0061] Next, what is shown in Fig. 9(c) is the third pattern of the pasting control by the height control mechanism, and the change from the "contact height" to the "separation height" is in the obliquely upward direction in the rear of the pasted half-cut double-sided tape. It is so to speak a pulling-up operation in the reverse direction. As described above, since the half-cut double-sided tape with a release liner is originally cut into small pieces, it is pulled obliquely upward in the rear so as to return while leaving the half-cut double-sided tape with a release liner of the small piece already pasted at the pasting position. It is conceivable that the end of the half-cut double-sided tape with a release liner of the small piece at the boundary of the pasting position follows obliquely upward in the rear. However, the friction with the object to be pasted is extremely small, and as shown in Fig. 9(c), it peels off from the object to be pasted and remains at the pasting position.

[0062] As described above, the adhesive tape pasting device 100 repeats the stroke of pasting the half-cut double-sided tape 210 when the object to be pasted that relatively travels one after another comes directly below using the adhesive tape 200 with a release liner. For example, when the object to be pasted that is traveling comes directly below, "pasting start" of pasting the half-cut double-sided tape with the height of the rotating body 132 set to the "contact height", "pasting period" of relatively moving the object to be pasted over a predetermined length to paste the half-cut double-sided tape 200, when the pasting of the predetermined length is completed, "pasting end" of pulling up and separating the height of the rotating body 132 upward so as to be the "separation height", and shifting to "pasting preparation" of waiting for the travel of the next object to be pasted. In this way, the pasting stroke is repeated with the process of "pasting start" - "pasting period" - "pasting end" - "pasting preparation" as one stroke.

[0063] In the above description, the adhesive tape sticking device 100 has been described as traveling in the traveling direction and sticking to the object to be stuck. Conversely, the adhesive tape sticking device 100 may not travel, and the object to be stuck may travel below the adhesive tape sticking device 100. That is, it is sufficient that the adhesive tape sticking device 100 and the object to be stuck relatively travel and move. During the traveling process, the height of the adhesive tape sticking device 100 and the height of the object to be stuck may also change relatively.

[0064] Next, a configuration example in which the sticking and pressing portion 130 has a suspension mechanism and a steering function will be described. FIG. 10 is a diagram simply showing the suspension mechanism and the steering mechanism provided in the sticking and pressing portion 130. FIG. 10(a) shows an example of the movement of the suspension mechanism provided in the sticking and pressing portion 130, and FIG. 10(b) shows an example of the movement of the steering mechanism provided in the sticking and pressing portion 130. The suspension movement mechanism is one in which the support mechanism 132 includes a swing mechanism that swings the rotating body 130 up and down. The steering movement mechanism is one in which the support mechanism 132 includes a mechanism that changes the angle of the rotating body 130 in the horizontal plane. Here, there are various suspension movement mechanisms that enable the vertical movement of the rotating body 131 with respect to the object to be stuck. As shown in FIG. 10(a), in the support mechanism 132 that supports the rotating body 131, a configuration in which an elastic body such as a spring that swings the rotation axis of the rotating body 131 in the vertical direction is incorporated, a configuration in which an air spring is incorporated, etc. are also possible. Further, for example, the entire rotating body 131 may be composed of an elastic body such as a rubber material or a flexible ring, or the rotating body 131 may have a multilayer structure and at least the surface layer may be composed of an elastic body such as a rubber material or a flexible ring (illustration is omitted).

[0065] As shown in Fig. 10(b), the steering motion mechanism only needs to be able to control the support mechanism 132 that supports the rotation axis of the rotating body 131 to change the support angle of the rotation axis within the horizontal plane. It may be a mechanism that actively changes the angle by external support, or it may be a mechanism in which the angle changes passively according to the traveling direction of the improved pasting device 400. The above is the outline of the movement of the entire pasting device 100 of the present invention.

Example 2

[0066] As Example 2, a configuration example will be described in which a plurality of sets of a roll body mounting portion 110, a pasting and pressing portion 130, and a release liner recovery portion 120 are provided as a set in the axial directions of the roll body rotation axis and the release liner rotation axis for the pasting device 100A of the adhesive tape of the present invention. Fig. 11 is a diagram simply showing the configuration of the pasting device 100A of the adhesive tape of the present invention according to Example 2. In Fig. 11, similar to Fig. 1, a front view is centered, and a plan view, a bottom view, a left side view, and a right side view are shown in the up, down, left, and right directions. Further, below the bottom view, there is a perspective view of the bottom surface viewed obliquely from a diagonal direction. Fig. 12 is a diagram simply showing the inside of the configuration of the pasting device 100A of the adhesive tape of the present invention according to Example 2 with the member corresponding to the cover removed from the housing 160. It shows a state in which a roll of the adhesive tape 200 with a release liner is mounted. Similar to Fig. 2, Fig. 12 also shows a plan view, a bottom view, a left side view, and a right side view in the up, down, left, and right directions centered on the front view. Further, below the bottom view, there is a perspective view of the bottom surface viewed obliquely from a diagonal direction.

[0067] As shown in FIGS. 11 and 12, the adhesive tape pasting device 100A of the present invention according to Example 2 has the same configuration as that in FIGS. 1 and 2, including a roll body mounting portion 110, a release liner recovery portion 120, a pasting and pressing portion 130, a gear mechanism 140, a switch mechanism 150 for device operation, and a housing 160. However, in this Example 2, the roll body mounting portion 110, the pasting and pressing portion 130, and the release liner recovery portion 120 are combined into one set, and in the axial direction of each of the roll body rotation shaft 112 and the release liner rotation shaft 121, a plurality of sets (three sets in this example) of the set of the roll body mounting portion 110, the pasting and pressing portion 130, and the release liner recovery portion 120 are provided, and it is structured such that a plurality of sets (three in this example) of the adhesive tape 210 can be pasted simultaneously. As shown in FIG. 11, even when the housing 160 is attached, it can be seen that in the pasting and pressing portion 130 visible from the opening 161 of the adhesive tape pasting device 100A of Example 2, three adhesive tapes 200 with release liners are arranged in parallel. Also, as shown in FIG. 12, in the internal structure, it can be seen that in the adhesive tape pasting device 100A of Example 2, the roll bodies of the adhesive tape 210 are arranged in three rows in the rotation axis direction, and the roll bodies of the release liner 220 are arranged in three rows in the rotation axis direction. In this configuration example, the pasting and pressing portions 130 are also arranged in three rows in the rotation axis direction, but it may also be one integrated pasting and pressing portion 130 composed of three, or three pasting and pressing portions 130 each supported by an independent support mechanism 132.

[0068] FIG. 13 is a diagram showing an outline of the flow of the movement of the entire adhesive tape pasting device 100A of the present invention according to Example 2. As shown in FIGS. 13(a) to 13(b), the pasting and pressing portion 130 of the adhesive tape pasting device 100 is operated to move along the pasting location on the surface of the object to be pasted. At that time, the adhesive tape 200 with a release liner exposed on the surface of the sticking and pressing part 130 rotates while coming into contact with the sticking position on the surface of the object to be stuck. As shown in FIG. 13(b), as the sticking device 100 of the adhesive tape moves, the adhesive tape 200 with a release liner is stuck to the sticking position on the surface of the object to be stuck by its adhesive force and remains, leaving a sticking track along its movement track. In this example, since the roll bodies of the adhesive tapes 210 are arranged in three rows in the rotation axis direction and the sticking and pressing parts 130 are also arranged in three rows in the rotation axis direction, the sticking process of three adhesive tapes can be executed at once.

[0069] FIG. 14 is a diagram showing an example of the sticking traces of various adhesive tapes 210 when the sticking device 100A of the adhesive tape according to Example 2 is used. FIG. 14(a) shows the sticking trace of a continuous "continuous tape" that is integrally formed in a strip shape without a cut. It simply shows the state of sticking three rows of linear adhesive tapes 210. FIG. 14(b) shows an example of the sticking trace of the half-cut tape 210 in a discontinuous state where the single-sided tape and the double-sided tape are appropriately cut. Here, an example of the half-cut double-sided tape 210 is used. The sticking traces of three rows of linear half-cut double-sided tapes 210 are shown. Actually, the half-cut double-sided tapes are strip-shaped fragments adjacent to each other, so the interval between the strip-shaped double-sided tape pieces is small, but here, the interval is deliberately enlarged for easy understanding of the shape and sticking trace of each strip-shaped double-sided tape piece and simply shown. FIG. 14(c) is a diagram simply showing the state of sticking the half-cut double-sided tape along an arc-shaped curve on the surface of a planar object to be stuck. The sticking traces of three rows of curved half-cut double-sided tapes 210 are shown. When it becomes curved like this, the interval between the strip-shaped fragments is large on the outside and small on the inside, but since each strip-shaped fragment is cut in the advancing direction, the interval can be adjusted freely. Thus, it can be understood that a curve can be drawn in the sticking trace of the half-cut double-sided tape 210. Although this is simply an example of an arc here, it can be understood that an irregular curve can also be drawn. FIG. 14(d) is a diagram briefly showing a state where a half-cut double-sided tape is attached along a curved surface on the surface of a curved object to be attached. Thus, according to the attaching device 100 for the adhesive tape of the present invention, since a strip-shaped double-sided tape can draw an attaching trace along a curve or a curved surface, the half-cut double-sided tape 210 can be attached to the surfaces of various objects to be attached, and the usage of the double-sided tape is expanded. In this FIG. 14, only an example of the attaching trace is shown, and it will be understood that various attaching traces are possible.

[0070] Next, in the configuration according to the second embodiment, a configuration in which the attaching and pressing portion 130 has a suspension mechanism and a steering function will be described. FIG. 15 is a diagram briefly showing the suspension mechanism and the steering mechanism provided in the attaching and pressing portion 130. FIG. 15(a) shows an example of the movement of the suspension mechanism provided in the attaching and pressing portion 130, and FIG. 15(b) shows an example of the movement of the steering mechanism provided in the attaching and pressing portion 130. The suspension movement mechanism is one in which the support mechanism 132 includes a swing mechanism that swings the rotating body 130 up and down. In this configuration example, since each attaching and pressing portion 130 has a suspension movement mechanism for the object to be attached, the suspension movement mechanisms of those attaching and pressing portions 130 can be made independent of each other. Therefore, as shown in FIG. 15(a), even when there are fine irregularities on the surface of the object to be attached, if the suspension movement mechanisms of the respective attaching and pressing portions 130 are independent of each other, they can move up and down independently along the fine irregularities on the surface of the object to be attached, and the adhesive tape can be beautifully applied. In the example of FIG. 15(a), the left diagram shows a state where the three rows of attaching and pressing portions 130 are in contact with a flat surface. The central diagram shows that the three rows of attaching and pressing portions 130 are in contact with a curved surface, and the suspension function of the central attaching and pressing portion 130 acts upward. The right diagram shows that the three rows of attaching and pressing portions 130 are in contact with a curved surface, and the suspension function of the central attaching and pressing portion 130 acts downward. In this way, since the three-column sticking and pressing part 130 has an independent suspension function, the adhesive tape 210 can be neatly attached along a curved surface with fine irregularities. Also, in this example, as shown in FIG. 15(b), each sticking and pressing part 130 is provided with an independent steering movement mechanism, and a support mechanism 132 that supports the rotation axis of the rotating body 131 can be controlled to change the support angle of the rotation axis within a horizontal plane. The above is the outline of the movement of the entire sticking device 100A of the present invention according to the second embodiment.
