Description

Technical Field

[0001] The present disclosure generally relates to a tape cutting system and a tape pasting method. More specifically, the present disclosure relates to a tape cutting system for cutting an adhesive tape and a tape pasting method using the tape cutting system.

Background Art

[0002] Patent Document 1 discloses a tape pasting method. In this method, an adhesive tape is continuously guided to both side surfaces of a prismatic member sequentially and intermittently transferred along a transfer path, and the adhesive tape is cut and pasted in accordance with the front end and the rear end of the prismatic member.

[0003] In this method, the front end of the transferred prismatic member is detected by a detection means and temporarily stopped. While it is stopped, the tape tips of a pair of adhesive tape reels rotatably supported on both sides of the transfer path are respectively attracted by suction transfer means and guided to both side surfaces of the front end portion of the prismatic member and crimped. Next, the suction transfer means releases the suction and returns to the original position. On the other hand, while the prismatic member with the adhesive tape is further transferred, the adhesive tape is sequentially crimped toward the rear end of the prismatic member by pressing means arranged on both sides thereof along the transfer path. Then, at a stage before the pasting of the adhesive tape to the prismatic member is completed, the rear end of the prismatic member is detected again at a predetermined position and temporarily stopped, and the adhesive tape is cut by a cutting means that aligns the rear end of the prismatic member and the rear end of the adhesive tape. During that time, the new tape tip of the cut adhesive tape reel is adsorbed by the suction transfer means, and on the other hand, the prismatic member is further transferred to complete the pasting.

BEST MODE FOR CARRYING OUT THE INVENTION

[0011] The tape cutting system and the tape pasting method according to the embodiments of the present disclosure will be described with reference to the drawings. Each of the drawings described in the following embodiments is a schematic diagram, and the ratios of the sizes and thicknesses of the respective components in the drawings do not necessarily reflect the actual dimensional ratios.

[0012] (1) Embodiment (1.1) Tape cutting system FIG. 1 is a perspective view showing a tape cutting system 100 according to the present embodiment.

[0013] Hereinafter, for the sake of convenience, a three-axis (X-axis, Y-axis, and Z-axis) of a right-handed three-dimensional orthogonal coordinate system will be defined as shown in FIG. 1 for the tape cutting system 100 and described. Also, for the sake of convenience of explanation, the direction along the X-axis is defined as the front-rear direction, the positive direction of the X-axis is "front", and the opposite is "rear". Also, the direction along the Y-axis is defined as the left-right direction, the positive direction of the Y-axis is "right", and the opposite is "left". Also, the direction along the Z-axis is defined as the up-down direction, the positive direction of the Z-axis is "up", and the opposite is "down". However, the definitions of the axes and directions in the present disclosure only indicate the relative positional relationship between the members of the tape cutting system 100 and do not limit the orientation during the use of the tape cutting system 100 or the like.

[0014] As shown in FIGS. 1 and 2, the tape cutting system 100 includes a tape reel 1, a tape extraction chuck 2, a tape holding portion 3, a tape cutting portion 4, a moving mechanism 5, a tape receiving portion 6, and a sorting and pasting portion 7. In FIG. 2, the illustration of the tape cutting portion 4 is omitted.

[0015] As shown in FIGS. 1 and 2, an adhesive tape 9 is wound around a tape reel 1. The adhesive tape 9 is a single-sided tape having an adhesive surface 91 and a non-adhesive surface 92. The adhesive tape 9 is wound around the tape reel 1 such that the adhesive surface 91 faces inward. The end of the adhesive tape 9 is drawn downward from the tape reel 1. The end of the adhesive tape 9 drawn downward from the tape reel 1 goes around a guide roller 11 and is held by, for example, a tape holding chuck 12 (see FIGS. 2 and 3).

[0016] As shown in FIG. 3, the tape extraction chuck 2 has a pair of clamping portions 21. Note that FIG. 3 is a perspective view of the main part (around the tape holding portion 3) of the tape cutting system 100 as viewed obliquely from above and in front.

[0017] The tape extraction chuck 2 is configured to extract the adhesive tape 9 from the tape reel 1. The tape extraction chuck 2 is configured to extract the adhesive tape 9 from the tape reel 1 such that the non-adhesive surface 92 of the adhesive tape 9 faces upward.

[0018] Specifically, the tape extraction chuck 2 is movable in the left-right direction within a predetermined movable range. For example, at the right end position of the movable range, the tape extraction chuck 2 sandwiches the end of the adhesive tape 9 on the left side of the tape holding chuck 12 between the pair of clamping portions 21. Then, with the end of the adhesive tape 9 sandwiched, the tape extraction chuck 2 moves leftward to the left end position (the position shown in FIGS. 1 to 3) of the movable range. Thereby, the tape extraction chuck 2 can extract the adhesive tape 9 from the tape reel 1. In FIGS. 1 to 3, the adhesive tape 9 is shown in a state of being extracted by the tape extraction chuck 2.

[0019] The tape holding portion 3 is configured to hold the adhesive tape 9 drawn from the tape reel 1.

[0020] As shown in FIGS. 1 to 3, the tape holding portion 3 includes a plurality (here, 12) of first suction portions 31.

[0021] The first suction section 31 is a rectangular block. Multiple first suction sections 31 are arranged in a comb-like pattern. In this disclosure, "multiple members are arranged in a comb-like pattern" means that multiple members are arranged in one direction with spacing between each of one or two members. Here, the multiple first suction sections 31 are arranged in the left-right direction with spacing between each first suction section 31.

[0022] The multiple (12 in this case) first suction units 31 are divided into two or more sets (5 in this case), with at least two first suction units 31 forming one set. Here, each of the two or more sets contains two or three first suction units 31. At least two first suction units 31 in one set are connected to each other by a rectangular block-shaped connecting part 32. At least two first suction units 31 and the connecting part 32 constitute a first suction head 30 that is U-shaped or E-shaped when viewed from above. In this way, the tape holding unit 3 has two or more first suction heads 30. Note that it is not essential that the tape holding unit 3 has two or more first suction heads 30; all (12) first suction units 31 may be connected to a single connecting part 32 to constitute a single first suction head 30.

[0023] As shown in Figure 4, the first suction section 31 has a first ventilation hole 319 on its lower surface 311. In this case, the first suction section 31 has multiple (5 or 10) first ventilation holes 319 on its lower surface 311, but the number of first ventilation holes 319 is not particularly limited.

[0024] The first vent hole 319 is connected to an L-shaped pipe 33 (see Figure 3) which is connected to the rear end of the coupling part 32, via a through-hole that penetrates the interior of the first suction part 31 and the coupling part 32. By connecting, for example, a vacuum pump to the pipe 33, air can be drawn in through the first vent hole 319.

[0025] For example, as shown in Figure 3, with the lower surfaces 311 of multiple first suction parts 31 in contact with the upper surface of the adhesive tape 9, air is drawn in by a vacuum pump from each of the pipes 33 of two or more first suction heads 30, causing the adhesive tape 9 to be attracted to the lower surfaces 311 of the multiple first suction parts 31. In other words, the tape holding part 3 can hold the adhesive tape 9 by attracting it to the lower surfaces 311 of each of the multiple first suction parts 31.

[0026] As described above, the tape dispensing chuck 2 pulls out the adhesive tape 9 from the tape reel 1 so that the non-adhesive surface 92 of the adhesive tape 9 faces upward. Therefore, the tape holding unit 3 holds the adhesive tape 9 with the lower surfaces 311 of the multiple first suction parts 31 facing the non-adhesive surface 92 (upper surface). This makes it difficult for the adhesive surface 91 of the adhesive tape 9 to stick to the tape holding unit 3, and facilitates the transfer of the tape piece 90 from the tape holding unit 3 to the tape receiving unit 6 (described later).

[0027] The tape cutting section 4 cuts the adhesive tape 9, which is being held by the tape holding section 3, to create a tape piece 90.

[0028] The tape cutting unit 4 cuts the adhesive tape 9 into one or more tape pieces 90. Here, the tape cutting unit 4 cuts the portion of the adhesive tape 9 held by the tape holding unit 3 into the same number of tape pieces 90 as the number of first suction heads 30 (5 pieces).

[0029] As shown in Figure 3, the tape cutting unit 4 cuts the portion of the adhesive tape 9 held by the tape holding unit 3 between adjacent first suction heads 30 (along the cutting line 99 shown in Figure 3). The tape cutting unit 4 also cuts the adhesive tape 9 between the rightmost first suction head 30 and the tape holding chuck 12. It is preferable that the tape holding chuck 12 holds the adhesive tape 9 before the portion between the rightmost first suction head 30 and the tape holding chuck 12 is cut. This prevents the end of the adhesive tape 9 from falling after it has been cut by the tape cutting unit 4.

[0030] As shown in Figure 1, the tape cutting unit 4 includes a laser irradiation unit 41. The laser irradiation unit 41 is equipped with, for example, a CO2 laser. The laser irradiation unit 41 cuts the adhesive tape 9 by irradiating it with laser light L1 (see Figure 3) from above. As shown in Figure 3, the laser irradiation unit 41 cuts the adhesive tape 9 into two or more tape pieces 90 by irradiating the adhesive tape 9 with laser light L1 at the planned cutting location (cutting line 99) on the adhesive tape 9.

[0031] Because the tape cutting unit 4 includes the laser irradiation unit 41, the cycle time can be shortened compared to, for example, cutting the adhesive tape 9 using a cutting blade. In particular, by using the laser beam L1, the adhesive tape 9 can be cut simultaneously at multiple locations, further shortening of the cycle time can be achieved.

[0032] Furthermore, when cutting the adhesive tape 9 using a cutting blade, the adhesive from the tape 9 may adhere to the cutting blade, requiring periodic maintenance such as removing the adhesive or replacing the cutting blade. In contrast, by using the laser irradiation unit 41, the frequency of maintenance of the tape cutting unit 4 can be reduced.

[0033] As shown in Figure 3, the upper surface 312 of at least one first suction section 31 (the third first suction section 31 from the right) has an inclined surface 313 at its edge (right end). In this way, the edge of the upper surface 312 of the first suction section 31 is cut, making it difficult for the laser beam L1 to hit the upper surface 312 of the first suction section 31.

[0034] The tape pieces 90 cut by the tape cutting unit 4 are held by the tape holding unit 3. Here, one corresponding tape piece 90 is held in each of the two or more first suction heads 30.

[0035] Each first suction head 30 has at least two first suction parts 31 (each tape piece 90 is attracted to the lower surface 311 of at least two first suction parts 31), so that each first suction head 30 can stably hold the tape piece 90.

[0036] As shown in Figures 1 and 2, the moving mechanism 5 includes a first moving mechanism 51. The first moving mechanism 51 is configured to move the tape holding section 3.

[0037] The first moving mechanism 51 includes a support rotating section 510. The support rotating section 510 includes a support plate 511 and a lifting and lowering rotating section 512.

[0038] As shown in Figure 3, the support plate 511 supports the tape holding unit 3. The support plate 511 is plate-shaped. Two or more (five in this case) first suction heads 30 of the tape holding unit 3 are fixed to the first edge (front edge) of the support plate 511.

[0039] The lifting and rotating unit 512 moves (lifts and lowers) the support plate 511 in the vertical direction. The lifting and rotating unit 512 also rotates the support plate 511. The lifting and rotating unit 512 rotates the support plate 511 around a rotation axis that is aligned in the vertical direction.

[0040] As shown in Figure 2, two or more (five in this case) first suction heads 30 are also fixed to the second edge (rear edge) of the support plate 511. By arranging two or more sets of first suction heads 30 on both the first and second edges of the support plate 511 in this way, the cutting of the adhesive tape 9 and the transfer of the tape piece 90 to the tape receiving section 6 (described later) can be performed in parallel. This reduces the cycle time.

[0041] The tape receiving unit 6 is configured to receive the tape piece 90 held by the tape holding unit 3 from the tape holding unit 3.

[0042] As shown in Figures 1 and 5, the tape receiving section 6 includes multiple (in this case, 16) second suction sections 61. Figure 6 is a perspective view of the main part of the tape cutting system 100 (around the tape receiving section 6) from the front and slightly above.

[0043] As shown in Figure 5, the second suction portion 61 is a rectangular block. Multiple second suction portions 61 are arranged in a comb-like pattern. Multiple second suction portions 61 are arranged in a left-right direction with a gap between each set of one or two second suction portions 61. Multiple comb-like second suction portions 61 are spaced apart so that they can interlock with multiple comb-like first suction portions 31. In this disclosure, "multiple comb-like first suction portions 31 and multiple comb-like second suction portions 61 interlock" means that multiple first suction portions 31 and multiple second suction portions 61 are arranged in one direction so that sets of one or two first suction portions 31 and sets of one or two second suction portions 61 are arranged alternately. Here, multiple first suction units 31 and multiple second suction units 61 are arranged in one direction, with pairs of one first suction unit 31 and one or two second suction units 61 alternating.

[0044] The multiple (16 in this case) second suction units 61 are divided into two or more sets (five in this case), with at least two second suction units 61 forming one set. Here, each of the two or more sets contains three or four second suction units 61. At least two second suction units 61 in one set are connected to each other by block-shaped connecting parts 62. The second suction head 60 is composed of at least two second suction units 61 and connecting parts 62. Thus, the tape receiving unit 6 has two or more (five in this case) second suction heads 60. Here, the number of second suction heads 60 (five) is the same as the number of first suction heads 30 (five). The two or more second suction heads 60 correspond one-to-one with the two or more first suction heads 30.

[0045] As shown in Figure 6, the second suction section 61 has a second ventilation hole 619 on its lower surface 611. In this case, the second suction section 61 has multiple (5 or 10) second ventilation holes 619 on its lower surface 611, but the number of second ventilation holes 619 is not particularly limited.

[0046] The second vent hole 619 is connected to a vent rod 63 (see Figure 1) via a through-hole that penetrates the interior of the second suction section 61 and the coupling section 62. The vent rod 63 is formed to be long in the vertical direction. The lower end of the vent rod 63 is connected to the rear end of the coupling section 62. By connecting, for example, a vacuum pump to the vent rod 63, air can be drawn in from the second vent hole 619. Two or more vent rods 63 are provided in a one-to-one ratio to correspond to two or more second suction heads 60.

[0047] The moving mechanism 5 further comprises a second moving mechanism 52. The second moving mechanism 52 is configured to move the tape receiving unit 6.

[0048] As shown in Figures 1 and 2, the second moving mechanism 52 includes a lifting mechanism 521 and a horizontal moving mechanism 522.

[0049] The lifting mechanism 521 moves the tape receiving section 6 in the vertical direction. The lifting mechanism 521 moves two or more second suction heads 60 of the tape receiving section 6 in the vertical direction by, for example, moving two or more ventilation rods 63 back and forth in the vertical direction.

[0050] As shown in Figure 2, the horizontal movement mechanism 522 comprises a first rail mechanism 523 and a second rail mechanism 524. The first rail mechanism 523 moves the tape receiving section 6 in the front-to-back direction. The second rail mechanism 524 moves the tape receiving section 6 in the left-to-right direction.

[0051] In this way, the tape receiving unit 6 can move forward, backward, left, right, up, and down by the second moving mechanism 52.

[0052] Referring to Figures 7 to 11, the method for transferring the tape piece 90 from the tape holding unit 3 to the tape receiving unit 6 will be explained. Note that in Figures 7 to 11, the number and shape of the first suction units 31 and the number and shape of the second suction units 61 differ from those of the embodiment, but this is solely for illustrative purposes.

[0053] First, as shown in Figure 7, the moving mechanism 5 positions the tape holding unit 3 and the tape receiving unit 6 facing each other in the front-to-back direction, with the tape pieces 90 being held on the lower surfaces 311 of the multiple first suction units 31 of the tape holding unit 3. Here, the moving mechanism 5 positions the tape holding unit 3 and the tape receiving unit 6 facing each other in the front-to-back direction by rotating the support plate 511 180° using the lifting and lowering rotation unit 512 of the support rotating unit 510, starting from a state where the adhesive tape 9 held by the tape holding unit 3 has been cut into five tape pieces 90 by the tape cutting unit 4 (see Figure 3). The tape holding unit 3 and the tape receiving unit 6 face each other in the front-to-back direction such that one or two second suction units 61 are positioned between two adjacent first suction units 31. Furthermore, the tape holding unit 3 and the tape receiving unit 6 are positioned such that the multiple first suction units 31 are located below the multiple second suction units 61.

[0054] Next, as shown in Figure 8, the moving mechanism 5 moves the tape holding section 3 and the tape receiving section 6 relative to each other so that they move closer together. Here, the moving mechanism 5 moves the tape receiving section 6 forward using the first rail mechanism 523 of the horizontal moving mechanism 522, thereby bringing the tape receiving section 6 closer to the tape holding section 3. As a result, as shown in Figure 8, the comb-shaped first suction sections 31 and the comb-shaped second suction sections 61 interlock. That is, the moving mechanism 5 moves the tape receiving section 6 relative to the tape holding section 3 so that the comb-shaped second suction sections 61 interlock with the comb-shaped first suction sections 31.

[0055] Next, as shown in Figure 9, the moving mechanism 5 moves the tape holding unit 3 and the tape receiving unit 6 relative to each other so that the lower surfaces 311 of the multiple first suction units 31 and the lower surfaces 611 of the multiple second suction units 61 are at the same height. Here, the moving mechanism 5 moves the tape receiving unit 6 downward using the lifting mechanism 521. As a result, the lower surfaces 611 of the multiple second suction units 61 come into contact with the upper surface (non-adhesive surface 92) of the tape piece 90 held by the tape holding unit 3.

[0056] Next, air is drawn in through the second ventilation holes 619 of the multiple second suction units 61 to hold the tape piece 90 in the tape receiving unit 6. As a result, the tape piece 90 is held in both the tape holding unit 3 and the tape receiving unit 6.

[0057] Next, suction from the first ventilation holes 319 of the multiple first suction units 31 is stopped. As a result, the tape piece 90 is held only by the tape receiving unit 6.

[0058] Next, as shown in Figure 10, the moving mechanism 5 moves the tape receiving section 6 downward relative to the tape holding section 3. Here, the moving mechanism 5 moves the tape receiving section 6 downward using the lifting mechanism 521.

[0059] In this embodiment, the multiple second suction sections 61 have a shape that allows them to descend by passing between the multiple first suction sections 31. This facilitates the transfer of tape pieces 90 from the tape holding section 3 to the tape receiving section 6.

[0060] Finally, as shown in Figure 11, the moving mechanism 5 moves the tape holding section 3 and the tape receiving section 6 relative to each other so that they move away from each other. Here, the moving mechanism 5 moves the tape receiving section 6 away from the tape holding section 3 by moving the tape receiving section 6 backward using the first rail mechanism 523 of the horizontal moving mechanism 522.

[0061] In this way, the tape piece 90 can be transferred from the tape holding unit 3 to the tape receiving unit 6.

[0062] The sorting and attaching unit 7 is configured to attach the tape pieces 90 held by the tape receiving unit 6 to the object 8 (see Figure 13). The sorting and attaching unit 7 is configured to attach two or more tape pieces 90, each individually held by two or more second suction heads 60 in the tape receiving unit 6, to the object 8 individually (i.e., sorted).

[0063] As shown in Figures 1, 2, 12, and 13, the distribution and application unit 7 is equipped with two or more (five in this case) movable bodies 71. Note that in Figures 12 and 13, the shapes of the moving mechanism 5, tape receiving unit 6, and movable bodies 71 are shown in a simplified manner.

[0064] Two or more mobile bodies 71 correspond one-to-one with two or more second suction heads 60. In other words, the multiple second suction units 61 are divided into two or more sets, each containing at least two second suction units 61, and two or more mobile bodies 71 correspond one-to-one with two or more sets containing at least two second suction units 61.

[0065] Each moving body 71 moves forward, backward, left, and right together with the corresponding second suction head 60 by the horizontal movement mechanism 522. Here, two or more moving bodies 71 move together in the forward and backward direction by the first rail mechanism 523 of the horizontal movement mechanism 522. On the other hand, two or more moving bodies 71 can move individually in the left and right directions by the second rail mechanism 524 of the horizontal movement mechanism 522.

[0066] Furthermore, two or more movable bodies 71 correspond one-to-one with two or more ventilation rods 63. Each ventilation rod 63 is held on a movable body 71 so as to be rotatable around its axis. Each ventilation rod 63 is also movable up and down relative to its corresponding movable body 71. As the ventilation rods 63 move up and down relative to the movable body 71, the second suction heads 60 connected to the lower ends of the ventilation rods 63 move up and down. In other words, each of the two or more movable bodies 71 is configured to move up and down at least two second suction parts 61 included in the corresponding set of two or more sets. In this way, by the two or more movable bodies 71 individually moving the two or more second suction heads 60, it becomes possible to individually attach the two or more tape pieces 90 cut by the tape cutting part 4 to the application area 81 of the object 8.

[0067] Referring to Figures 12 and 13, the method of attaching tape pieces 90 to the object 8 using the distribution and attachment unit 7 will be explained. The object 8 is not particularly limited, but here it is a long, flat board 80 in the left-right direction, as shown in Figure 13.

[0068] First, as shown in Figure 12, the tape receiving unit 6 holds the tape pieces 90 received from the tape holding unit 3 by suction to the lower surfaces 611 of the multiple second suction units 61. Here, two or more tape pieces 90 are individually held by two or more second suction heads 60 of the tape receiving unit 6 (the tape is pre-cut by the tape cutting unit 4 before being transferred from the tape holding unit 3 to the tape receiving unit 6).

[0069] Next, using an appropriate transport means (which may be manual), the board 80, which is the object 8, is placed below the tape receiving section 6. Then, the first rail mechanism 523 of the moving mechanism 5 moves two or more movable bodies 71 together in the front-rear direction so that the tape receiving section 6 is positioned above the board 80. In addition, the second rail mechanism 524 of the moving mechanism 5 moves two or more movable bodies 71 individually in the left-right direction so that they are positioned above the areas 81 on the board 8 where two or more tape pieces 90 are to be attached.

[0070] Next, as shown in Figure 13, the lifting mechanism 521 of the moving mechanism 5 lowers two or more second suction heads 60 to individually attach the tape pieces 90. That is, the tape receiving unit 6 is moved over the attachment target area 81 of the object 8, and suction from the multiple second ventilation holes 619 is stopped. As a result, the tape pieces 90 are individually attached to the attachment target area 81 on the upper surface of the board 80, which is the object 8.

[0071] Here, the lower surface 611 of the second suction part 61 that holds the tape piece 90 in the second suction head 60 is planar (see Figure 6). That is, the lower surface 611 of the second suction part 61 includes a planar pressing surface that presses and adheres the tape piece 90 to the object 8. This allows the tape piece 90 to be firmly pressed and adhered to the object 8.

[0072] (1.2) Tape application method The tape application method for attaching a tape piece 90 to an object 8 using the tape cutting system 100 of this embodiment includes, as shown in Figure 14, a first suction step ST1, a tape cutting step ST2, a relative movement step ST3, a second suction step ST4, a first vacuum breaking step ST5, and a second vacuum breaking step ST6.

[0073] The first suction step ST1 includes holding the adhesive tape 9 in the tape holding unit 3 by drawing air in through multiple first ventilation holes 319 in the multiple first suction parts 31, while the lower surfaces 311 of each of the multiple first suction parts 31 of the tape holding unit 3 are in contact with the upper surface of the adhesive tape 9 (see Figures 1 to 3). Here, the upper surface of the adhesive tape 9 is the non-adhesive surface 92.

[0074] The tape cutting step ST2 includes cutting the adhesive tape 9 held by the tape holding unit 3 into tape pieces 90 using the tape cutting unit 4 (see Figure 3). Here, the tape cutting unit 4 includes a laser irradiation unit 41, and the adhesive tape 9 is cut into tape pieces 90 by irradiating it with laser light L1 from above using the laser irradiation unit 41.

[0075] The relative movement step ST3 includes moving the tape receiving section 6 relative to the tape holding section 3 so that the comb-shaped second suction sections 61 interlock with the comb-shaped first suction sections 31 (see Figures 7 to 9).

[0076] The second suction step ST4 includes holding the tape piece 90 in the tape receiving section 6 by sucking air from the multiple second ventilation holes 619 in the multiple second suction sections 61 while the multiple second suction sections 61 are engaged with the multiple first suction sections 31.

[0077] The first vacuum breaking step ST5 includes stopping the suction from the plurality of first vents 319 after the second suction step ST4.

[0078] The second vacuum breaking step ST6 includes moving the tape receiving unit 6 over the application area 81 of the object 8 after the first vacuum breaking step ST5, thereby stopping the suction from the multiple second vents 619 (see Figure 13). The second vacuum breaking step ST6 causes the tape piece 90 to be applied to the application area 81 of the object 8.

[0079] Thus, the tape cutting system 100 of this embodiment can be used to attach adhesive tape 9 (tape piece 90) to a desired part (part 81 to be attached) of an object 8.

[0080] (2) Variant The embodiments described above are merely one of many embodiments of this disclosure.
