Description

The present invention relates to a sheet manufacturing apparatus and a sheet manufacturing method.

For example, when handling multiple piece-shaped product parts such as various tags (e.g., RFID tags) and labels, a product sheet is used in which the product parts are attached at predetermined intervals to a strip-shaped release sheet. A configuration disclosed in Patent Document 1 is known as an apparatus for manufacturing such a product sheet.

In Patent Document 1, a product sheet is manufactured by peeling off the portion other than the product portion from a product portion forming layer that is temporarily attached to a release sheet as an unnecessary portion. The product portion forming layer is formed in advance with a product portion cutout that corresponds to the outer shape of the product portion, and a division cutout that divides the unnecessary portion into left and right portions. The unnecessary portion is peeled off by peeling off the two unnecessary portions separated by the division cutout at different positions.

FIG. 2 is a plan view in which a part of the configuration of the sheet manufacturing apparatus according to the embodiment is omitted. FIG. 4 is a partial side view of a recovery section according to the embodiment.

The sheet manufacturing apparatus according to the embodiment will be described in detail below with reference to the attached drawings. Note that the present invention is not limited to the embodiment described below, and can be modified as appropriate without departing from the gist of the invention. For the sake of convenience, some components may be omitted in the following drawings.

Figure 1 is a front view of a sheet manufacturing apparatus according to an embodiment. Figure 2 is a schematic perspective view of the periphery of a peeling unit according to an embodiment. As shown in Figure 1, the sheet manufacturing apparatus 10 according to this embodiment includes a laminating unit 20, a payout unit 30, a cutting unit 40, a peeling unit 50, and a recovery unit 60. As shown in Figure 2, the sheet manufacturing apparatus 10 produces a product sheet TS in which product portions T are attached to a strip-shaped release sheet PS at predetermined intervals after passing through the peeling unit 50. Each component of the sheet manufacturing apparatus 10 is supported via a frame (not shown) or the like.

In this embodiment, the product part T is formed in a rectangular planar shape, with its long sides parallel to the width direction of the release sheet PS and its short sides parallel to the longitudinal direction (extension direction) of the release sheet PS. The product part T is not particularly limited, but will be described below as an example in the form of an RFID tag.

As shown in FIG. 1, the lamination unit 20 includes a release sheet roll 21 on which a strip-shaped release sheet PS is wound in a roll, and a lower roll 22, an intermediate roll 23, and an upper roll 24 for forming the product part T. A strip-shaped base sheet 23a that serves as the base material of the product part T is wound in a roll on the intermediate roll 23, and an antenna and an IC chip that constitute an RFID tag are provided at predetermined intervals on the base sheet 23a. The lower roll 22 and the upper roll 24 are wound with strip-shaped protective sheets 22a, 24a that protect the base material, and an adhesive layer is laminated on the surface of the protective sheets 22a, 24a facing the base sheet 23a. In addition, a double-sided tape is laminated on the surface of the lower protective sheet 22a facing the release sheet PS.

The lamination unit 20 further includes a drive roller 26 and a pinch roller 27 that sandwiches the release sheet PS, the protective sheets 22a, 24a, and the base sheet 23a between the drive roller 26. The drive roller 26 is driven to rotate by a drive source 28 including a motor or the like. The drive roller 26 and the pinch roller 27 sandwich and stack the release sheet PS, the protective sheets 22a, 24a, and the base sheet 23a together to form the processing sheet MS before the product part T is formed. In the processing sheet MS, the product part forming layer TL is formed by stacking the protective sheets 22a, 24a, and the base sheet 23a. In addition, the product part forming layer TL is adhered (temporarily attached) to the release sheet PS via double-sided tape.

The drive roller 26 and pinch roller 27 of the lamination unit 20 pay out the processing sheet MS from left to right in FIG. 1, which is the longitudinal direction of the processing sheet MS and the pay-out direction. The processing sheet MS passes through the cutting unit 40 and peeling unit 50 to become the product sheet TS, but the product sheet TS is also sandwiched between the drive roller 31 and pinch roller 32 and a force is applied to pay out in the pay-out direction. Here, the pay-out unit 30 is composed of the drive roller 31 and pinch roller 32 and the drive roller 26 and pinch roller 27 of the lamination unit 20.

The cutting section 40 forms various cuts, described below, in the product part forming layer TL as the processing sheet MS is unwound in the longitudinal direction. The cutting section 40 includes a punching blade 41 disposed above the processing sheet MS, a lifting body 42 that holds the punching blade 41 from above, and a receiving body 43 that is below the processing sheet MS and faces the punching blade 41 with the processing sheet MS sandwiched between them. The lifting body 42 is movable vertically at a predetermined stroke by a drive device (not shown), and is capable of pressing the punching blade 41 into the product part forming layer TL of the processing sheet MS.

Before describing the specific configuration of the punching blade 41, the cuts formed by the punching blade 41 in the product portion forming layer TL will be described below with reference to FIG. 3. FIG. 3 is a plan view of the processing sheet immediately after cuts are formed in the cutting section of the embodiment. As shown in FIG. 3, the product portion forming layer TL has multiple product portion cuts CL1 formed at predetermined intervals in the payout direction according to the outer edge shape of the product portion T. The product portion cuts CL1 are formed in a rectangular shape with long sides parallel to the width direction of the product portion forming layer TL and short sides parallel to the payout direction, just like the product portion T.

In the product part forming layer TL, the inside of the product part notch CL1 becomes the product part T, and the outside of the product part notch CL1 becomes the unnecessary part US. A dividing notch CL2 is formed in the unnecessary part US at a position that connects adjacent product part notches CL1 in the payout direction. The dividing notch CL2 is formed in the widthwise center of the unnecessary part US (product part forming layer TL) and divides the unnecessary part US into a first unnecessary part US1 and a second unnecessary part US2. In this embodiment, the first unnecessary part US1 is located at the bottom in Figure 3, sandwiched between the dividing notch CL2, and the second unnecessary part US2 is located at the top in the same figure.

The product part notches CL1 are formed by a pressing operation using a punching blade 41 (see FIG. 1) to form a set of five (shown enclosed in a two-dot dashed rectangle in FIG. 3). Here, the dividing notches CL2 located on both sides of the five product part notches CL1 have an X-shaped portion formed by two intersecting notches, and this X-shaped portion is formed to extend in a direction inclined relative to the payout direction. On the other hand, the other dividing notches CL2 have a +-shaped portion formed by two intersecting notches, in other words, they are formed by a notch that extends parallel to the payout direction and continues to the product part notches CL1, and a notch that is perpendicular (intersecting) to the notch.

Subdivision cuts CL3 are formed in the unnecessary parts US located on both sides of the product part cut CL1 upstream and downstream in the payout direction. The subdivision cuts CL3 are connected to the long side of the product part cut CL1 and are formed at predetermined intervals in the width direction of the product part forming layer TL, which is a direction that intersects the payout direction. The subdivision cuts CL3 subdivide the unnecessary parts US adjacent to the product part T in the payout direction.

Next, the specific configuration of the punching blade 41 will be described below with reference to FIG. 4. FIG. 4 is a view of the punching blade of the embodiment as seen from below. As shown in FIG. 4, the punching blade 41 includes a plurality of product part punching blades 44 (five in this embodiment) that form the product part cutouts CL1, a dividing punching blade 45 that forms the dividing cutouts CL2, and a subdivision punching blade 46 that forms the subdivision cutouts CL3.

The dividing die cutter blades 45 are formed at positions that connect adjacent product part die cutter blades 44 in the payout direction, and are formed so that the two blades cross to form a + shape according to the dividing cut CL2. The dividing die cutter blades 45 located on both sides of the five product part die cutter blades 44 in the payout direction have a shape that is bent at one point. As a result, the dividing cut CL2 located on both sides in the payout direction during one pressing operation of the die cutter blade 41 are formed to have a portion where the two cuts cross to form an X shape during the next pressing operation.

The subdivision die-cutting blades 46 are connected to both the upstream and downstream sides of the product part die-cutting blade 44 in the payout direction, and are arranged in a direction perpendicular to (intersecting) the payout direction at a predetermined interval.

Returning to FIG. 1, the peeling unit 50 is provided downstream of the cutting unit 40 in the payout direction. The peeling unit 50 also includes a first peeling blade 51 and a second peeling blade 52 that are arranged along the upper surface of the processing sheet MS that is paid out downstream of the cutting unit 40. The first peeling blade 51 and the second peeling blade 52 are arranged apart in the payout direction, with the second peeling blade 52 being arranged downstream of the first peeling blade 51 in the payout direction.

The tip of each peeling blade 51, 52 is formed at an acute angle, and is disposed at an angle relative to the payout direction and width direction of the processing sheet MS (see FIG. 5). As shown in FIG. 2, the first peeling blade 51 sharply folds back only the first unnecessary portion US1 of the processing sheet MS being paid out, and peels it off from the release sheet PS. The second peeling blade 52 sharply folds back only the second unnecessary portion US2 of the processing sheet MS from which the first unnecessary portion US1 has been peeled off, and peels it off from the release sheet PS.

Each peeling blade 51, 52 presses down on the processing sheet MS from above while peeling as described above. After the first unnecessary portion US1 and the second unnecessary portion US2 are peeled off by each peeling blade 51, 52, the product sheet TS is supplied downstream in the payout direction with the product portions T attached to the release sheet PS at predetermined intervals. Although not shown, the product sheet TS after passing through the peeling section 50 can be supplied to a device that peels the product portions T from the release sheet PS and attaches them to predetermined positions, or it can be cut into sheets or rolled up for transport, storage, and use.

The first unnecessary portion US1 and the second unnecessary portion US2 are arranged in a comb-tooth shape that is symmetrical in the width direction of the processing sheet MS. Specifically, the first unnecessary portion US1 and the second unnecessary portion US2 each have a band-shaped portion US1a, US2a that extends in the payout direction. In addition, the first unnecessary portion US1 and the second unnecessary portion US2 each have a protruding portion US1b, US2b that protrudes from one side of the width direction of the band-shaped portion US1a, US2a and is formed at predetermined intervals in the extension direction of the band-shaped portion US1a, US2a.

When peeling the unnecessary portion US in the peeling section 50, the peeling positions of the first unnecessary portion US1 and the second unnecessary portion US2 are shifted in the payout direction so that the unnecessary portion US is divided into the first unnecessary portion US1 and the second unnecessary portion US2. As a result, when the first unnecessary portion US1 is peeled off, the second unnecessary portion US2 remains attached to the peel-off sheet PS, so that the product portion T can be prevented from being peeled off together with the unnecessary portion US and rising up together.

When the first peeling blade 51 peels off the first unnecessary part US1, the first unnecessary part US1 and the second unnecessary part US2 are separated by the dividing cut CL2. In this division, the dividing cut CL2 is formed with two intersecting cuts, so that the first unnecessary part US1 can be smoothly separated from the second unnecessary part US2.

Furthermore, since multiple subdivision cuts CL3 are formed in a row on the long side of the product part cut CL1 to subdivide the protrusions US1b, US2b, it is possible to smoothly separate the protrusions US1b, US2b from the product part T when the unnecessary part US is peeled off. This also makes it possible to prevent the product part T from being peeled off together with the unnecessary part US and from rising up together, and also makes it possible to prevent the protrusions US1b, US2b from being torn and remaining on the release sheet PS.

Returning to FIG. 1, the recovery section 60 includes a first guide roller 61, a second guide roller 62, a joining roller 63, and a take-up roll 64, and recovers the unnecessary portion US peeled off by the peeling section 50.

The first guide roller 61 loops around the first unnecessary part US1 peeled off by the first peeling blade 51 and guides it to the joining roller 63. The second guide roller 62 loops around the second unnecessary part US2 peeled off by the second peeling blade 52 and guides it to the joining roller 63.

The adhesive layer side of each unnecessary part US1, US2 contacts and is rotated around each guide roller 61, 62, so the surface is coated with fluororesin, silicone resin, etc., to ensure smooth unwinding of each unnecessary part US1, US2.

Figure 5 is a plan view of a sheet manufacturing apparatus according to an embodiment, with some of the configuration omitted. In Figure 5 and Figure 6 described later, the cuts extending in the direction intersecting the payout direction at the dividing cut CL2 and the subdivision cut CL3 are omitted. As shown in Figure 5, a single first collar 65 is attached to the first guide roller 61. The first collar 65 is provided adjacent to the opposite side of the protruding portion US1b in the band-shaped portion US1a of the first unnecessary portion US1.

The first collar 65 is provided so that its mounting position in the axial direction of the first guide roller 61 can be adjusted. For example, the first guide roller 61 is pressed into a hole in the first collar 65, and the axial position and positioning can be adjusted by the frictional resistance between them. By adjusting the position of the first collar 65, it is possible to adjust the position of the first unnecessary part US1 around the first guide roller 61. By adjusting this position of the loop, it is possible to adjust the payout direction (angle) of the first unnecessary part US1 after it is folded back by the first peeling blade 51, and it is possible to adjust the peeling state of the first unnecessary part US1.

A single second collar 66 is attached to the second guide roller 62. The second collar 66 is provided adjacent to the opposite side of the protruding portion US2b in the strip portion US2a of the second unnecessary portion US2.

The second collar 66 is provided so that its mounting position in the axial direction of the second guide roller 62 can be adjusted. For example, the second guide roller 62 is pressed into a hole in the second collar 66, and the axial position and positioning can be adjusted by the frictional resistance between them. By adjusting the position of the second collar 66, it is possible to adjust the position at which the second unnecessary part US2 is wrapped around the second guide roller 62. By adjusting this wrapping position, it is possible to adjust the payout direction (angle) of the second unnecessary part US2 after it is folded back by the second peeling blade 52, and it is possible to adjust the peeling state of the second unnecessary part US2.

The first unnecessary portion US1 and the second unnecessary portion US2 that are fed between the guide rollers 61, 62 and the joining roller 63 have larger drooping protrusions US1b, US2b as they move away from the guide rollers 61, 62 (see FIG. 1). When the protrusions US1b, US2b reach the joining roller 63, they are almost entirely drooping downward.

The joining roller 63 wraps around the first unnecessary part US1 and the second unnecessary part US2 that have passed from the peeling section 50 through the guide rollers 61 and 62, and guides them to the winding roll 64. The joining roller 63 is provided with a pair of joining collars 68 located on both sides in the width direction of the first unnecessary part US1 and the second unnecessary part US2 that it guides.

The separation width of the pair of joining collars 68 is set smaller than the width dimensions of the first unnecessary portion US1 and the second unnecessary portion US2. Therefore, the joining collar 68 guides the first unnecessary portion US1 and the second unnecessary portion US2 to approach each other as they pass through the guide rollers 61, 62 and proceed in the payout direction. As a result, the strip portion US1a of the first unnecessary portion US1 and the strip portion US2a of the second unnecessary portion US2 are adjacent to each other at a position where they reach the joining roller 63, or are quite close to each other with a gap between them.

The pair of joining collars 68 are provided so that their mounting positions in the axial direction of the joining roller 63 can be adjusted. For example, the joining roller 63 is pressed into a hole in the joining collar 68, and the axial position adjustment and positioning can be performed by the frictional resistance between them. By adjusting the position of each joining collar 68, the separation width of each joining collar 68 can be adjusted, and the relative positions of the first unnecessary part US1 and the second unnecessary part US2, which are close to each other, can be adjusted.

The joining roller 63 reverses the first unnecessary part US1 and the second unnecessary part US2 and guides them to the winding roll 64. By this reversal, the joining roller 63 intertwines the protruding part US1b of the first unnecessary part US1 and the protruding part US2b of the second unnecessary part US2 so that they are alternately positioned in the payout direction (see Figures 1 and 6 in addition to Figure 5).

Figure 6 is a partial side view of the recovery section in the embodiment. Figure 6A is a view from the arrow A in Figure 1, and Figure 6B is a view from the arrow B in Figure 1 (a view from the back of Figure 6A). As shown in Figure 6, the winding roll 64 winds up the first unnecessary part US1 and the second unnecessary part US2, which are in an entangled state after passing through the joining roller 63 (see Figure 5). The winding roll 64 has a winding shaft 64a and flange parts 64b provided on both axial sides of the winding shaft 64a. The winding roll 64 is driven to rotate by a driving source 70 (see Figure 1) including a motor, etc., and exerts a force to wind up each of the unnecessary parts US1 and US2.

When collecting the unnecessary parts US1 and US2 in the collection section 60, the protrusion US1b of the first unnecessary part US1 and the protrusion US2b of the second unnecessary part US2 are entangled as they pass through the joining roller 63, and can be wound up after being bundled together. This makes it possible to prevent the length of each unnecessary part US1 and US2 from the peeling position in the peeling section 50 to the entanglement position at the joining roller 63 from changing over time. As a result, it is possible to stabilize the tension of each unnecessary part US1 and US2, and also to stabilize winding by suppressing the occurrence of differences in tension in each unnecessary part US1 and US2.

Here, assuming that the unnecessary parts US1, US2 are not entangled, unlike the above embodiment, there is a high possibility that the unnecessary parts US1, US2 wound around the winding shaft 64a will be biased toward one of the pair of flanges 64b. In this case, there will be some places where the winding diameter of the unnecessary parts US1, US2 is relatively large and some places where it is small in the axial direction of the winding shaft 64a. If winding is continued in this state, at least one of the unnecessary parts US1, US2 will move to the place where the winding diameter is small, causing a problem that the tension of the unnecessary parts US1, US2 will change.

In this regard, in the present embodiment, the unnecessary parts US1 and US2 are wound up in an entangled state as shown in FIG. 6, so that the width of the entangled state is kept constant, and the winding diameter can be maintained constant in the axial direction of the winding shaft 64a. This makes it possible to prevent the unnecessary parts US1 and US2 from moving in the axial direction of the winding shaft 64a, and to stabilize the tension of the unnecessary parts US1 and US2.

Next, the sheet manufacturing method for the product sheet TS using the sheet manufacturing apparatus 10 will be described below. This sheet manufacturing method is carried out in the following order: lamination process, cutting process, peeling process, and recovery process.

As shown in FIG. 1, in the lamination process, the release sheet PS, the protective sheets 22a, 24a, and the base sheet 23a are sandwiched and laminated together by the drive roller 26 and pinch roller 27. This forms the processing sheet MS before the product part T is formed. The processing sheet MS is formed with the product part forming layer TL that forms the product part T by laminating the protective sheets 22a, 24a, and the base sheet 23a, and the release sheet PS to which the product part forming layer TL is adhered via double-sided tape.

The cutting process is carried out on the processing sheet MS that has completed the lamination process and is in the process of being unwound in the longitudinal direction. In the cutting process, the lifting body 42 is raised and lowered at the timing when the processing sheet MS that is being intermittently unwound stops, thereby pressing the die cutting blade 41 against the product part forming layer TL. As a result, the product part die cutting blade 44, the division die cutting blade 45, and the subdivision die cutting blade 46 (see Figure 4) of the die cutting blade 41 form the product part notches CL1, the division notches CL2, and the subdivision notches CL3 in the product part forming layer TL, as shown in Figures 2 and 3.

The peeling process is carried out on the processing sheet MS that has been cut and is fed downstream in the feed direction from the cutting section 40. In the peeling process, first, the first peeling blade 51 folds back only the first unnecessary portion US1 of the processing sheet MS being fed and peels it off from the release sheet PS. In this peeling, the second unnecessary portion US2 is pressed down from above by the first peeling blade 51 and remains adhered to the release sheet PS together with the product portion T. As a result, the first unnecessary portion US1 is separated from the second unnecessary portion US2 by the dividing cut CL2 in the unnecessary portion US.

In the peeling process, downstream of the first peeling blade 51 in the payout direction of the processing sheet MS, the second peeling blade 52 folds back only the second unnecessary portion US2 and peels it off from the release sheet PS. In this peeling process, the product portion T remains adhered to the release sheet PS, and after passing through the second peeling blade 52, the product sheet TS with the product portion T attached to the release sheet PS at predetermined intervals is supplied downstream in the payout direction.

A recovery process is carried out for each of the unnecessary parts US1 and US2 that have been peeled off by the peeling blades 51 and 52 during the peeling process. In the recovery process, the first unnecessary part US1 and the second unnecessary part US2 that have passed through the guide rollers 61 and 62 from the peeling section 50 are guided by the joining roller 63 to the winding roll 64, and each of the unnecessary parts US1 and US2 are wound up and recovered by the winding roll 64.

In the recovery process, the pair of joining collars 68 on the joining roller 63 guide the unnecessary parts US1 and US2 so that they approach each other. Also, in the recovery process, the unnecessary parts US1 and US2 are inverted by the joining roller 63 before being wound up by the winding roll 64, so that the protruding portion US1b of the first unnecessary part US1 and the protruding portion US2b of the second unnecessary part US2 are intertwined so that they are positioned alternately in the payout direction.

As described above, in the above embodiment, in a single sheet manufacturing apparatus 10, the cutting section 40 can form each of the incisions CL1 to CL3, and the peeling section 50 and the recovery section 60 can peel off and recover the unnecessary portion US. This eliminates the need for a dedicated device for only forming the incisions or a dedicated device for winding up the raw material on which the incisions have been formed, as in the conventional method, in order to prepare a raw material roll on which the incisions have been formed in advance. As a result, in the embodiment, it is possible to avoid an increase in the number of various devices, and in turn, to avoid an increase in the space required to install the devices. In addition, in the embodiment, the formation of the incisions CL1 to CL3 and the peeling off and recovery of the unnecessary portion US can be performed by a continuous unwinding of the processing sheet MS, thereby shortening the manufacturing time of the product sheet TS.

The present invention is not limited to the above-described embodiment, and can be modified in various ways. In the above-described embodiment, the size, shape, direction, etc. shown in the attached drawings are not limited to these, and can be modified as appropriate within the scope of the effects of the present invention. In addition, the present invention can be modified as appropriate without departing from the scope of the purpose of the present invention.

In the above embodiment, the lamination unit 20 performs lamination, adhesion, etc. to form the processing sheet MS in which the product portion forming layer TL is adhered to the release sheet PS, but this is not limited to the above. For example, the processing sheet MS may be prepared in advance as a raw material roll and fed to the cutting unit 40, and in such a configuration the lamination unit 20 can be omitted.

The product part T may be a variety of pieces or labels other than an RFID tag. Furthermore, the planar shape of the product part T may be modified in various ways, such as to a polygonal shape other than a circle or a rectangle, as long as the unnecessary part US can be peeled off in the same manner as in the above embodiment.

In addition, in the above embodiment, the subdivision cuts CL3 are formed in the unnecessary parts US located on both the upstream and downstream sides of the product part cuts CL1 in the payout direction, but they may be formed only on the downstream side in the payout direction.

In the above embodiment, the dividing cut CL2 is formed so that two cuts intersect, but it may be formed from a single cut parallel to the payout direction. However, forming the dividing cut CL2 so that two cuts intersect is advantageous in that it can more smoothly promote the division of the first unnecessary part US1 from the second unnecessary part US2.
