Summary of the Invention
Problems to be Solved by the Invention
[0004] In the labeler (sheet sticking device) described in Patent Document 1, a label roll storage device 41 (supply means) for supplying a label roll (third base fabric) is provided only on the side of the main labeling machine 12 (first sticking means). However, when a connection means similar to this is also provided on the side of the preliminary labeling machine 3 (second sticking means), there arises a disadvantage that the device becomes large-sized.
[0005] An object of the present invention is to provide a sheet sticking device and a sheet sticking method capable of preventing the device from becoming large-sized.
Means for Solving the Problems
[0006] The present invention employs the configuration described in the claims.
Effects of the Invention
[0007] According to the present invention, since both the first and second adhesive means are equipped with a single supply means capable of supplying the third raw material, it is possible to prevent the device from becoming larger. [Brief explanation of the drawing]

The system is located near an adherend transport means 60, which is composed of a belt conveyor or roller conveyor, and is capable of transporting a plurality of adherends WK sequentially. In this embodiment, the first to third raw material rolls RS1 to RS3 are supplied to the sheet application device EA while wound around the first to third support tubes RS1P to RS3P, which are supported by the first to third receiving plates RS1B to RS3B, respectively.
[0011] The first adhesive means 10 includes a feeding means 11 for feeding out the first raw material RS1, a guide roller 12 for guiding the first raw material RS1, a release plate 13 as a release means for folding back the first release sheet RL1 at the release edge 13A and peeling the first adhesive sheet AS1 from the first release sheet RL1, a pressing roller 14 as a pressing means for pressing and attaching the first adhesive sheet AS1 to the adherend WK, and a drive roller 15 supported by the output shaft (not shown) of a rotating motor 15A as a drive device, which sandwiches the first release sheet RL1 between itself and a pinch roller 15B. The system also includes a recovery roller 16, which is supported by the output shaft of a drive device (not shown) and constantly applies a predetermined tension to the first release sheet RL1 that is between it and the pinch roller 15B while the sheet application device EA is in automatic operation, and which serves as a recovery means for recovering the first release sheet RL1; and a final end detection device 17, which is composed of imaging means such as a camera or projector, and various sensors such as optical sensors or ultrasonic sensors (hereinafter simply referred to as "various sensors, etc."), and which detects the final end RS1E (see Figure 1(B)) of the first raw material RS1.

The linear motor 11K and the cutting blade 11M are connected rear end forming means that form the connected rear end RS1R on the first roll RS1.
[0012] The second adhesive means 20 has the same configuration as the first adhesive means 10, except that the position of the support plate 21C, the position of the linear motor 21K, the position of the recovery case 21N, the position of the final end detection device 27, and the shape of the raw material guide plate 21H are different. The explanation can be made by changing the tens digit of the numbering in the configuration description of the first adhesive means 10 from 1 to 2, changing AS1, RL1, and RS1 to AS2, RL2, and RS2 respectively, and changing "first" to "second" in each configuration. Therefore, only the illustrations are provided (numbering other than in Figure 1(A) is in parentheses), and a detailed explanation of its configuration is omitted.
[0013] The connecting means 30 includes a positioning means 31 capable of both positioning the connecting rear end RS1R of the first roll RS1 and the connecting front end RS3F of the third roll RS3 to be brought close together and positioned in a predetermined location, and positioning the connecting rear end RS2R of the second roll RS2 and the connecting front end RS3F of the third roll RS3 to be brought close together and positioned in a predetermined location, and a connecting means 32 capable of both connecting the first roll RS1 and the third roll RS3, and connecting the second roll RS2 and the third roll RS3. The positioning means 31 comprises a lead end detection device 31A composed of various sensors, etc., which detects the lead end RS3T of the third raw material RS3; a suction pad 31D supported on the output shaft 31C of a linear motor 31B, which serves as a drive device, and capable of being held by a depressurization means (holding means) not shown, such as a depressurization pump or a vacuum ejector; a cutting blade 31G supported on the output shaft 31F of a linear motor 31E, which serves as a drive device, which cuts the third raw material RS3 to form a connecting tip RS3F on the third raw material RS3; a so-called articulated robot 31H, which serves as a drive device, composed of multiple arms, capable of displacing what is supported by the tip arm 31J, which is the work part, to any position and angle within its working range; a linear motor 31K, which serves as a drive device, supported on the tip arm 31J; and a pair of chuck arms 31M, each supported on a pair of sliders 31L. The connecting means 32 includes a support roller 32A that supports the fourth roll RS4 on which the connecting tape CT as a connecting member is temporarily attached to the strip-shaped release sheet RL4, a guide roller 32B that guides the fourth roll RS4, a release plate 32C that folds the release sheet RL4 back at the release edge 32D and peels the connecting tape CT from the release sheet RL4, a linear motor 32E that is a drive device and pressing means, a linear motor 32G that is a drive device supported by its slider 32F, and a connecting tape supported by its output shaft 32H and by a depressurization means (holding means) not shown, such as a depressurization pump or vacuum ejector, which peels the connecting tape The device includes a holding member 32J that adsorbs and holds the CT and presses the held connecting tape CT onto the first and third rolls of material RS1 and RS3, or the second and third rolls of material RS2 and RS3; a drive roller 32L supported on the output shaft (not shown) of a rotary motor 32K which serves as a drive device, which sandwiches the release sheet RL4 between itself and a pinch roller 32M; and a recovery roller 32N supported on the output shaft of a drive device (not shown), which constantly applies a predetermined tension to the release sheet RL4 between itself and the pinch roller 32M while the sheet application device EA is in automatic operation, and which serves as a recovery means for recovering the release sheet RL4.
[0014] The supply means 40 includes a support base 42 supported on the upper surface of a support shaft 42A into which the third support tube RS3P is fitted, which is supported by the slider 41A of the rail 41; a linear motor 44 as a drive device supported by the slider 43A of the linear motor 43 as a drive device; a pair of lift arms 45 supported by each of the two sliders 44A of the linear motor 44; a linear motor 47 as a drive device supported by the slider 46A of the linear motor 46 as a drive device; a suction pad 48 supported on the output shaft 47A of the linear motor 47 via a frame material 48A, which can be held by suction using a depressurization means (holding means) not shown, such as a depressurization pump or a vacuum ejector; and a linear motor 49 as a drive device which supports the linear rotary motor 11A with the first slider 49A and supports the linear rotary motor 21A with the second slider 49B.
[0015] The adhesive control means 50 includes a first detection device 51 composed of various sensors, a second detection device 52 equivalent to the first detection device 51, and a control device 53 such as a computer or sequencer that can control the operation of the first and second detection devices 51 and 52 and each means constituting the sheet adhesive device EA. The first and second detection devices 51 and 52 count (number) the first adherend WK (identical adherend WK) they detect as 1, for each adherend WK being transported from left to right of the first detection device 51 by the adherend transport means 60, and thereafter count each subsequent adherend WK sequentially with the same integer number following 1. The control device 53 recognizes and identifies adherend WKs that have the same count number from the first detection device 51 and the same count number from the second detection device 52 as being the same. As a result, the operation of the first and second adhesive means 10 and 20 is controlled by the control device 53 to eliminate the absence of the first and second adhesive sheets AS1 and AS2 from being applied to the adherend WK identified by the control device 53, as well as from being applied to multiple surfaces.
[0016] The operation of the sheet application device EA described above will now be explained. First, the user of the sheet application device EA (hereinafter simply referred to as "user") sets the first and second raw material rolls RS1 and RS2 and the fourth raw material roll RS4 on the sheet application device EA, which has the components positioned in the initial positions shown by the solid lines in Figure 1(A), as shown in the figure. The user then pulls out the support base 42, fits the third support tube RS3P onto the support shaft 42A, stacks the third raw material roll RS3 on the support base 42, and then returns the support base 42 to its initial position. The lead end RS3T of RS3 is temporarily secured with adhesive tape (not shown). Once the above operations are completed, the user inputs a signal to start automatic operation via an operating means (not shown), such as an operation panel or personal computer. The first and second adhesive means 10 and 20 then drive the rotary motors 15A and 25A, and feed out the first and second raw material rolls RS1 and RS2. When the leading edge of the first and second adhesive sheets AS1 and AS2 in the feeding direction is peeled off a predetermined length from the peeling edges 13A and 23A of the release plates 13 and 23, the driving of the rotary motors 15A and 25A is stopped. The connecting means 30 then drives the rotary motor 32K, and feed out the fourth raw material roll RS4. When the leading edge of the connecting tape CT in the feeding direction reaches a predetermined position near the peeling edge 32D of the release plate 32C, the driving of the rotary motor 32K is stopped.
[0017] Next, after the adherend WK, which has been transported by the adherend transport means 60, is detected and counted by the first detection device 51, when it reaches a predetermined position relative to the first adhesive means 10, the first adhesive means 10 drives the rotary motor 15A to feed out the first raw material RS1 in accordance with the moving speed of the adherend WK. As a result, the first adhesive sheet AS1 is peeled off from the first release sheet RL1, and the first adhesive sheet AS1 peeled off from the first release sheet RL1 is pressed and attached to the adherend WK by the pressure roller 14, as shown by the dashed line in Figure 1(A). After that, the entire leading first adhesive sheet AS1 is attached to the adherend WK, and when the leading edge in the feeding direction of the next first adhesive sheet AS1 following the leading first adhesive sheet AS1 is peeled off by a predetermined length at the release edge 13A of the release plate 13, the first adhesive means 10 stops driving the rotary motor 15A, and the same operation as described above is repeated thereafter.
[0018] Subsequently, the transport of the object WK by the object transport means 60 continues, and when the object WK is detected and counted by the second detection device 52, the control device 53 identifies the object WK from the counts obtained by the first detection device 51 and the second detection device 52, and determines whether the first adhesive sheet AS1 has been attached by the first adhesive means 10 or not. Next, for the object WK that the control device 53 has determined to have the first adhesive sheet AS1 attached, the control device 53 outputs a drive stop signal to the second adhesive means 20, so that the second adhesive means 20 does not attach the second adhesive sheet AS2. On the other hand, for any adherend WK that the control device 53 identifies as not having the first adhesive sheet AS1 attached, the control device 53 outputs a drive signal to the second adhesive means 20, causing the second adhesive means 20 to attach the second adhesive sheet AS2 in the same manner as the first adhesive means 10, and the same operation is repeated thereafter.
[0019] The above operation is repeated. As shown in Fig. 1(B), when the final end portion RS1E of the first web RS1 comes off the first support tube RS1P and is detected by the final end portion detection device 17, the pasting operation by the first pasting means 10 is stopped and the pasting operation by the second pasting means 20 is started. By this switching, the adherend WK to which the first adhesive sheet AS1 has not been pasted by the first pasting means 10 is specified by the determination by the above control device 53, so that non-pasting and double-pasting of the first adhesive sheet AS1 or the second adhesive sheet AS2 do not occur. Then, when the first pasting means 10 drives the rotation motor 15A to feed out the first web RS1 and the detection means (not shown) composed of various sensors and the like detects that the center between the first adhesive sheets AS1 is located on the right side of the cutting blade 11M as shown in Fig. 1(B), the first pasting means 10 stops driving the rotation motor 15A. At this time, the first pasting means 10 may drive a decompression means (holding means) not shown such as a decompression pump or a vacuum ejector to adsorb and hold the first web RS1 with the web guide plate 11H. Next, the first pasting means 10 drives the linear motion motor 11K, cuts the first web RS1 with the cutting blade 11M as shown by the solid line in Fig. 1(B) to form a connection rear end portion RS1R on the first web RS1, and then returns the cutting blade 11M to the initial position. The portion of the first web RS1 including the final end portion RS1E separated by the cutting of the cutting blade 11M is removed by the user or a conveying means not shown. Thereafter, when the first pasting means 10 drives the rotation motor 15A to feed out the first web RS1 and the detection means (not shown) composed of various sensors and the like detects that the connection rear end portion RS1R has reached the connection reference position 11E as shown in Fig. 2(C), the first pasting means 10 stops driving the rotation motor 15A. At this time, the first pasting means 10 may drive a decompression means (holding means) not shown such as a decompression pump or a vacuum ejector to adsorb and hold the connection rear end portion RS1R with the web guide plate 11H.
[0020] Next, the connecting means 30 drives the articulated robot 31H and the linear motor 31K, and the chuck arm 31M grips the first support tube RS1P, and the first receiving plate RS1B and the first support tube RS1P are placed into the recovery case 11N. Then, the first attaching means 10 and the supply means 40 drive the linear motor 11A and the linear motor 49, and the support plate 11C is lowered and passes below the raw material guide plate 11H, and as shown by the dashed line in Figure 1(A), the support plate 11C is moved directly below the linear motor 46. Subsequently, the supply means 40 drives the linear motors 43 and 44, and as shown by the dashed line in Figure 1(C), the lift arm 45 is moved below the uppermost third receiving plate RS3B which is fitted onto the support shaft 42A, and then the lift arm 45 is raised, lifting the third raw material RS3 together with the third receiving plate RS3B to a predetermined height. Subsequently, the supply means 40 drives the linear motor 46, the linear motor 47, and a pressure reducing means (not shown) to bring the suction pad 48 into contact with the upper surface of the third receiving plate RS3B, as shown by the dashed line in Figure 1(C), and begin the suction holding of the third receiving plate RS3B by the suction pad 48. Next, the supply means 40 drives the linear motors 43 and 44 to return the lift arm 45 to its initial position, and drives the linear motor 46 and the linear motor 47 to fit the third support tube RS3P onto the support shaft 11D, as shown by the dashed line in Figure 2(A), and place the third raw material RS3 on the support plate 11C. Then, the supply means 40 stops driving the pressure reducing means (not shown), releases the suction holding of the third receiving plate RS3B by the suction pad 48, and drives the linear motor 46 and the linear motor 47 to return the suction pad 48 to its initial position.
[0021] Next, the first attaching means 10 drives the linear rotation motor 11A to rotate the support plate 11C at a predetermined speed. As shown by the dashed-dotted line in FIG. 2(B), when the lead end detecting device 31A detects the lead end RS3T, the detection result is output to the first attaching means 10. As shown by the dashed-dotted line in the same figure, when the vicinity of the lead end RS3T is positioned at the adsorbable position of the suction pad 31D, the drive of the linear rotation motor 11A is stopped. Thereafter, the connecting means 30 drives the linear motor 31B and a decompression means (not shown). As shown by the dashed-dotted line in FIG. 2(B), after the vicinity of the lead end RS3T is adsorbed and held by the suction pad 31D, as shown in the same figure, the third original sheet RS3 is pulled out. When a detecting means (not shown) composed of various sensors or the like detects that the center between the third adhesive sheets AS3 is positioned directly above the cutting blade 31G, the drive of the linear motor 31B is stopped. Next, the connecting means 30 drives the articulated robot 31H and the linear motor 31K. As shown in FIG. 2(A), after the third original sheet RS3 is gripped by the chuck arm 31M, the linear motor 31E is driven. As shown in FIG. 2(B), the cutting blade 31G is slid on the cutting reference side 31N of the chuck arm 31M to cut the third original sheet RS3, and a connection destination end RS3F is formed on the third original sheet RS3. Then, the connecting means 30 drives the linear motors 31B and 31E to return the suction pad 31D and the cutting blade 31G to their initial positions. After that, the drive of the decompression means (not shown) is stopped, and the adsorption and holding of the third adhesive sheet AS3 by the suction pad 31D is released. Note that the portion of the third original sheet RS3 including the lead end RS3T separated by the cutting of the cutting blade 31G is removed by the user or a conveying means (not shown).
[0022] Next, the first attachment means 10 and the supply means 40 drive the linear motor 11A and the linear motor 49 to move the support plate 11C under the raw material guide plate 11H and return it to its initial position. At this time, the connecting means 30 drives the articulated robot 31H to guide the pulled-out third raw material RS3 so that it does not get caught on the raw material guide plate 11H, etc. When the support plate 11C returns to its initial position, the connecting means 30 drives the articulated robot 31H to move the chuck arm 31M gripping the third raw material RS3 into the connecting notch 11F, as shown in Figure 2(C), bringing the cutting reference edge 31N into close contact with the connecting reference position 11E, and positioning the connecting rear end RS1R of the first raw material RS1 and the connecting front end RS3F of the third raw material RS3 together. Subsequently, the connecting means 30 drives the rotary motor 32K and a depressurization means (not shown) to feed out the fourth raw material RS4, causing the leading connecting tape CT to be peeled off at the peeling edge 32D of the release plate 32C. When the leading edge of the next connecting tape CT following the leading connecting tape CT reaches a predetermined position near the peeling edge 32D of the release plate 32C, the driving of the rotary motor 32K is stopped. As a result, the connecting tape CT is held by the holding member 32J by suction, as shown in Figure 2(C). Next, the connecting means 30 drives the linear motor 32E to press and attach the connecting tape CT to the first release sheet RL1 and the third release sheet RL3, as shown by the dashed lines in Figures 2(C) and (D). After this, the driving of the depressurization means (not shown) is stopped to return the holding member 32J to its initial position, and the connecting means 30 drives the articulated robot 31H and the linear motor 31K to return the pair of chuck arms 31M to their initial positions. As a result, the third roll of material RS3 is connected to the first roll of material RS1 using connecting tape CT, and the third roll of material RS3 connected to the first roll of material RS1 becomes the first roll of material RS1, while the third support plate RS3B and third support pipe RS3P associated with it become the first support plate RS1B and first support pipe RS1P.
[0023] After this, the second adhesive means 20 continues to attach the second adhesive sheet AS2, and when the final end RS2E of the second raw material RS2 detaches from the second support tube RS2P and the final end RS2E is detected by the final end detection device 27, the first adhesive means 10 starts attaching the sheet, and then the second adhesive means 20 stops attaching the sheet. Due to this switching, the adherend WK to which the first adhesive sheet AS1 has been attached by the first adhesive means 10 is identified by the control device 53 described above. For adherend WK identified as having the first adhesive sheet AS1 attached, the control device 53 outputs a drive stop signal to the second adhesive means 20, and the second adhesive means 20 does not attach the second adhesive sheet AS2. As a result, there is no possibility of the first adhesive sheet AS1 or the second adhesive sheet AS2 being left unattached or overlapping on the adherend WK. The operation of connecting the connecting end RS3F of the third roll RS3 to the connecting rear end RS2R of the second roll RS2 is equivalent to the operation of connecting the connecting end RS3F of the third roll RS3 to the connecting rear end RS1R of the first roll RS1, except that the holding member 32J, which holds the connecting tape CT by suction, descends once, passes below the roll guide plate 11H, and then rises again to attach the holding connecting tape CT to the second release sheet RL1 and the third release sheet RL3, as shown by the dashed line in Figure 2(D). Therefore, a description of this operation is omitted.
[0024] According to the above embodiment, since both the first adhesive means 10 and the second adhesive means 10 are equipped with a single supply means 40 capable of supplying the third raw material RS3, it is possible to prevent the device from becoming larger.
[0025] The means and processes in the present invention are not limited in any way as long as they can perform the operations, functions, or processes described for those means and processes, and are certainly not limited in any way to the components or processes of a single embodiment shown in the above embodiments. For example, the first adhesive means can be anything that can unwind a first roll of material on which a first adhesive sheet is temporarily attached to a strip-shaped first release sheet, and attach the first adhesive sheet peeled off from the first roll to a substrate, and is not limited in any way as long as it is within the scope of the art in light of the common general knowledge at the time of filing (the same applies to other means and processes).
[0026] The first and second adhesive means 10 and 20 may be configured to attach the first and second adhesive sheets AS1 and AS2 to the rear surface or top surface of the adherend WK, or they may employ a drive device as a means for pressing members to move the pressing rollers 14 and 24 closer to and further away from the adherend WK, in order to prevent stress on or damage to the adherend WK, or the release sheets RL1 and RL2 collected by the recovery rollers 16 and 26 are cut, the release sheets RL1 and RL2 are removed from the recovery rollers 16 and 26 and discarded, and the first and second raw material rolls RS fed out by the first and second adhesive means 10 and 20 1. A means for replacing release sheets may be used to connect the release sheets RL1 and RL2 of RS2 to the recovery rollers 16 and 26. Alternatively, the first and second raw materials RS1 and RS2 may be cut to form connected rear ends RS1R and RS2R before the final ends RS1E and RS2E are detected by the final end detection devices 17 and 27. The system may or may not be equipped with final end detection devices 17 and 27 and means for forming connected rear ends. If not equipped, the final ends RS1E and RS2E may be positioned at the connection reference positions 11E and 21E as connected rear ends RS1R and RS2R. The dispensing means 11 and 21 may dispense first raw material rolls RS1 and RS2 in which a closed loop shape or a cut along the entire short width direction is formed in a strip-shaped adhesive sheet substrate that is temporarily attached to strip-shaped first and second release sheets RL1 and RL2, and predetermined areas partitioned by the cut are the first and second adhesive sheets AS1 and AS2. Alternatively, a strip-shaped adhesive sheet raw material in which a strip-shaped adhesive sheet substrate is temporarily attached to strip-shaped first and second release sheets RL1 and RL2 may be used, and while dispensing the strip-shaped adhesive sheet raw material, a closed loop shape or a cut along the entire short width direction is formed in the adhesive sheet substrate with a cutting blade as a cutting means, and first and second raw material rolls RS1 and RS2 in which predetermined areas partitioned by the cut are the first and second adhesive sheets AS1 and AS2. The first and second rolls RS1 and RS2, with strip-shaped first and second adhesive sheets AS1 and AS2 temporarily attached to RL2, may be fed out. When attaching the first and second adhesive sheets AS1 and AS2 to the adherend WK, the speed and tension of the fed-out first and second rolls RS1 and RS2 may be controlled to apply a predetermined tension to the first and second adhesive sheets AS1 and AS2, or to prevent tension from being applied. The first and second rolls RS1 and RS2 may be fed out from first and second rolls RS1 and RS2 that are not wound, for example, in a fanfold fold. The first and second adhesive sheets AS1 and AS2 that are not temporarily attached to the first and second release sheets RL1 and RL2 may be fed out. The collection cases 11N and 21N may be omitted. The pressing means may be configured such that, instead of the pressing rollers 14 and 24, the first and second adhesive sheets AS1 and AS2 are held by a holding member supported on the output shaft of a linear motor as a drive device and capable of being held by suction using a depressurizing means (holding means) not shown, such as a depressurizing pump or a vacuum ejector, and the first and second adhesive sheets AS1 and AS2 held by the holding member are pressed and attached to the object WK. Alternatively, instead of or in combination with the pressing rollers 14 and 24, a method using gas spraying, a brush-like member, a blade-like member, etc., may be used, and the materials used for these and the pressing rollers 14 and 24, etc., may be made of rubber, resin, sponge, metal, etc. The recovery means may be configured to recover the first and second release sheets RL1 and RL2 without winding them, for example by fan-folding them, shredding them with a shredder, or simply accumulating them haphazardly. It may also be provided in the sheet application device EA of the present invention, or it may not be provided.
[0027] The connecting means 30 may connect the third raw material RS3 to the first and second raw material rolls RS1 and RS2 by positioning the lead end RS3T as the connecting end RS3F and bringing it close to the connecting rear ends RS1R and RS2R without the positioning means 31 forming the connecting end RS3F, or by positioning the connecting end RS3F and the connecting rear ends RS1R and RS2R so that they overlap, or by positioning them without bringing the connecting rear ends RS1R and RS2R and the connecting end RS3F into contact, or by moving the connecting rear ends RS1R and RS2R without moving the connecting end RS3F, or by moving both the connecting end RS3F and the connecting rear ends RS1R and RS2R to bring the connecting rear ends RS1R and RS2R and the connecting end RS3F closer together and positioning, thereby connecting the third raw material roll RS3 to the first and second raw material rolls RS1 and RS2. The positioning means 31 may be a single unit as in the above embodiment, or it may be a combination of a first adhesive means 10 dedicated to positioning the third raw material roll RS3F by bringing it close only to the connecting rear end RS1R of the first raw material roll RS1, and a second adhesive means 20 dedicated to positioning the third raw material roll RS3F by bringing it close only to the connecting rear end RS2R of the second raw material roll RS2. The connecting means 32 may connect the third raw material RS3 to the first and second raw material RS1 and RS2 using adhesive, glue, stapler, welding, etc., in addition to the connecting tape CT. The connecting tape dispensing means, consisting of a support roller 32A, guide roller 32B, release plate 32C, rotating motor 32K, drive roller 32L, pinch roller 32M, and recovery roller 32N, may be positioned in the middle of the X-axis direction of the first and second adhesive means 10 and 20, or to the right of the second adhesive means 20, or at any other position. Instead of the linear motor 32E, linear motor 32G, and holding member 32J, a pressing means may be used. A configuration may be adopted in which a roller is used to supply the connecting tape CT while moving relative to the first and second adhesive means 10 and 20, and the connecting tape CT is pressed and attached to the connecting end RS3F and connecting rear end RS1R and RS2R with the pressing roller (for example, the configuration exemplified in the embodiment and modified examples of Japanese Patent Application Publication No. 2019-117834), or a single unit may be used as in the above embodiment, or both a unit dedicated to the first adhesive means 10 that is only capable of connecting the first raw material roll RS1 and the third raw material roll RS3, and a unit dedicated to the second adhesive means 20 that is only capable of connecting the second raw material roll RS2 and the third raw material roll RS3 may be used.
[0028] The supply means 40 may stack one or more third rolls RS3 horizontally without stacking them, or it may have two or more support shafts 42A, or it may be configured to raise the rail 41 up to a predetermined height by raising and lowering it with a linear motor as a drive device without using a lift arm 45, or it may be configured to lower a suction pad 48 and hold the third receiving plate RS3B by suction pad 48 without raising the third rolls RS3 to a predetermined height, or it may employ a drive device that supports and moves a linear rotary motor 11A and another drive device that supports and moves a linear rotary motor 21A.
[0029] The adhesive control means 50 may detect the object to be adhered WK at any position, such as in front of, above, or below the object to be adhered WK. Contact-type sensors may be used as the first and second detection devices 51 and 52, or non-contact-type sensors may be used. Alternatively, instead of or in combination with the configuration that identifies the object to be adhered WK by counting, the object to be adhered WK may be identified by imaging means such as a camera or projector. The sheet adhesive device EA of the present invention may or may not be equipped with such means.
[0030] In the above embodiment, the sheet application device EA moved the adherend WK without moving the first and second application means 10 and 20, and applied the first and second adhesive sheets AS1 and AS2 to the adherend WK. However, the first and second application means 10 and 20 may be moved either without moving the adherend WK or while moving the adherend WK, and the first and second adhesive sheets AS1 and AS2 may be applied to the adherend WK. The sheet application device EA may apply the second adhesive sheet AS2 to the adherend WK to which the first adhesive sheet AS1 has been applied by the first application means 10 using the second application means 20. Alternatively, when one of the first application means 10 or the second application means 20 is performing the adhesive sheet application operation, the application means that is not performing the adhesive sheet application operation may be moved away from the adherend WK (adherend transport means 60). Alternatively, the application means that is performing the adhesive sheet connection operation may be moved away from the adherend WK (adherend transport means 60). Furthermore, in order to prevent the adhesive sheet from being applied to the adherend by the raw material being fed out during the adhesive sheet connection operation, a drive device for feeding out the raw material may be provided upstream of the raw material feeding direction relative to the peeling means, and the raw material may be fed out instead of the rotary motors 15A and 25A. The object transport means 60 may or may not be provided in the sheet application device EA of the present invention.
[0031] The first to third raw materials RS1 to RS3 may all be the same raw material, or they may all be different raw materials, or some of them may be the same raw material and the others may be different, and they may not be supported by the first to third support plates RS1B to RS3B, nor may they be wound around the first to third support tubes RS1P to RS3P.
[0032] The material, type, shape, etc., of the first to third adhesive sheets AS1 to AS3, connecting tape CT, and adherend WK in the present invention are not particularly limited. For example, the first to third adhesive sheets AS1 to AS3, connecting tape CT, and adherend WK may be circular, elliptical, polygonal (such as triangle or square), or have other shapes. The first to third adhesive sheets AS1 to AS3 and connecting tape CT may also have adhesive properties such as pressure-sensitive or heat-sensitive adhesion. If heat-sensitive adhesive first to third adhesive sheets AS1 to AS3 or connecting tape CT are used, they may be bonded by providing a suitable heating means, such as a suitable coil heater or the heating side of a heat pipe, to heat the first to third adhesive sheets AS1 to AS3 or connecting tape CT. Furthermore, the first to third adhesive sheets AS1 to AS3 and connecting tape CT may be, for example, a single layer of adhesive only, a layer with an intermediate layer between the substrate and the adhesive layer, a layer with three or more layers including a cover layer on the upper surface of the substrate, or even a so-called double-sided adhesive sheet that allows the substrate to be peeled off the adhesive layer. The double-sided adhesive sheet may have a single or multi-layer intermediate layer, or a single or multi-layer without an intermediate layer. The adherend WK may be, for example, a single object such as food, a resin container, a semiconductor wafer such as a silicon semiconductor wafer or a compound semiconductor wafer, a circuit board, an information recording substrate such as an optical disc, a glass plate, a steel plate, a ceramic, a wooden board, or a resin, or a composite object formed from two or more of these, and any form of component or article can also be targeted. Note that the first to third adhesive sheets AS1 to AS3 may be replaced with any sheet, film, tape, etc., such as information label, decorative label, protective sheet, dicing tape, die attach film, die bonding tape, recording layer forming resin sheet, etc., based on their functional and practical applications.
[0033] The drive equipment in the above embodiment can be electric equipment such as rotary motors, linear motors, single-axis robots, articulated robots with two or more axes, actuators such as air cylinders, hydraulic cylinders, rodless cylinders, and rotary cylinders, or a combination of these directly or indirectly. In the above embodiment, if a rotating member such as a roller is used, a drive device for rotating the rotating member may be provided, the surface of the rotating member or the rotating member itself may be made of a deformable material such as rubber or resin, the surface of the rotating member or the rotating member itself may be made of a non-deformable material, other members such as rotating or non-rotating shafts or blades may be used instead of rollers, and if a means or member for pressing an object to be pressed, such as a pressing roller or pressing member, is used, in addition to rollers, round bars, blade materials, and brush-shaped members, a method of blowing gas such as air or gas may be used instead of or in combination with those exemplified above, and the pressing material may be made of a deformable material such as rubber, resin, or sponge, or it may be made of a non-deformable material such as metal or resin, and if a means for peeling an object to be peeled, such as a peeling plate, is used, in addition to or in combination with those exemplified above, a plate-shaped member may be used. 。 English: Round bars, rollers, and other components may be used, the material to be peeled off may be made of a deformable material such as rubber or resin, or a non-deformable material. If a support (holding) means or support (holding) member is used to support (hold) the supported member (held member), a configuration may be adopted in which the supported member is supported (held) by gripping means such as mechanical chucks or chuck cylinders, Coulomb force, adhesive (adhesive sheets, adhesive tapes), adhesive agents (adhesive sheets, adhesive tapes), magnetic force, Bernoulli adsorption, suction adsorption, drive equipment, etc. If a cutting means or cutting member is used to cut the member to be cut or to form cuts or cutting lines on the member to be cut, a cutter blade, laser cutter, ion beam, thermal power, heat, water pressure, electric heating wire, spraying of gas or liquid, etc. may be used instead of or in combination with the examples given above, or the material to be cut may be moved by combining appropriate drive equipment to perform the cutting.
