Abstract

PROBLEM TO BE SOLVED: To provide a sheet sticking apparatus and a sticking method which enable sticking speed to be improved and also a sheet to be surely raised irrespective of a material of the same or the like without scaling up the apparatus.SOLUTION: After an adhesive sheet S is stuck to a sticking target W by a releasing means 3 and a pressing means 4, the standing portion S2 of the adhesive sheet S passes through a raising plate 51 as the sticking target W is carried by a carrying means 7, whereby the standing portion S2 guided passively and automatically along a guide slope end 54 is raised. Therefore, another driving unit for raising the standing portion S2 can be dispensed with, so that a structure of the sheet sticking apparatus 1 can be simplified, and in addition, the scaling up of the apparatus can be prevented. Since another process for raising the standing portion S2 also can be dispensed with, a sticking cycle can be shortened and a plurality of adhesive sheets S can be efficiently and successively stuck.

Description

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

Conventionally, a pasting device for pasting an adhesive sheet such as a POP label on an adherend such as a container has been proposed (see, for example, Patent Document 1). Equipped with an adhesive part with a glue part (adhesive layer) provided in the half area and a paste-killing part (non-adhesive part) provided in the other half area, the adhesive layer of the adhesive part peels off It is supplied as a raw material temporarily attached to a sheet and is attached to the top surface of the container (the adherend surface of the adherend).
The sticking device described in Patent Document 1 raises the non-adhesive part by the rising plate of the label raising part, and folds the non-adhesive part in a double direction toward the adhesive part by the folding plate of the label bifold brazing part. After the brazing, the adhesive sheet is peeled off from the release sheet by the release plate, and the peeled adhesive sheet is pressed against the adherend surface of the adherend while being folded in two. In this way, the adhesive sheet affixed to the adherend surface is a non-adhesive part in which the supporting leg piece formed by the cut of the bent portion protrudes to the opposite side of the adhesive part and tries to return to the initial state by the elasticity of the base sheet. The support leg piece comes into contact with the adherend surface with the rising, so that the state where the non-adhesive portion rises from the adhesion portion and the adherend surface is maintained.

  However, in the conventional sticking device described in Patent Document 1, since the non-adhesive part and the adhesive part are folded in half before attaching the adhesive sheet to the adherend, the adhesive sheet is placed on the release sheet. Inconvenience that the adhesive sheet is stuck on the adherend while it is misaligned, and the adhesive sheet is clogged between the rising plate of the label raising part and the release plate. Will occur. In particular, such inconvenience becomes noticeable when the sticking speed (number of stickers per hour) is increased, so that the sticking speed cannot be increased. Furthermore, since the conventional sticking device is intended for an adhesive sheet in which the non-adhesive part is raised by the elasticity of the base sheet after sticking in a folded state, it has a base sheet with a material and thickness that can be plastically deformed. When the adhesive sheet is used as a target, there is a problem that the non-adhesive portion cannot be raised.

  An object of the present invention is to provide a sheet sticking apparatus and a sticking method that can increase the sticking speed without causing an increase in the size of the apparatus and can be reliably started up regardless of the material of the sheet. is there.

  In order to achieve the above object, the sheet sticking device of the present invention is such that an adhesive sheet having an adhesive layer on one surface of a base sheet having an adhesive portion and an upright portion is strip-like peeled through the adhesive layer. A sheet sticking device that peels off the adhesive sheet from a raw material temporarily attached to a sheet, and sticks the adhesive sheet to an adherend, a feeding means for feeding the raw material, and a peeling device for peeling the adhesive sheet from the release sheet A means for pressing and adhering the bonded portion of the peeled adhesive sheet to an adherend surface of the adherend to be transported; and accompanying the adherend to which the adhesive sheet is stuck A rising means for raising the upright portion of the adhesive sheet from the surface of the adherend to a predetermined angle, and the rising means extends in the conveying direction of the adherend and extends in the upright portion of the adhesive sheet. Standing tip inserted on one side And a rising guide portion that is connected to the downstream side in the conveying direction of the adherend from the rising tip portion and guides the rising portion in the rising direction away from the adherend surface. It is characterized by being.

At this time, the sheet sticking apparatus of the present invention uses the transport direction, the transport direction and the direction orthogonal to the adherend surface, the surface direction of the adherend surface orthogonal to the transport direction, and the transport direction as an axis. At least one of a rotation direction, a rotation direction with the transport direction and a direction orthogonal to the adherend surface as an axis, and a rotation direction with the surface direction of the adherend surface orthogonal to the transport direction as an axis. It is preferable to provide displacement means for displacing the rising means in one direction.
Moreover, in the sheet sticking device of the present invention, the rising guide portion is separated from the adherend surface from the upstream side in the transport direction toward the downstream side, and the surface direction of the release sheet orthogonal to the transport direction. It is preferable to have a guide inclined end edge inclined in each direction.

  On the other hand, in the sheet sticking method of the present invention, an adhesive sheet having an adhesive layer on one surface of a base sheet having an adhesive portion and an upright portion is temporarily attached to a strip-shaped release sheet via the adhesive layer.

  According to the present invention as described above, since it is not necessary to provide a bending device or the like for bending the adhesive sheet, the size of the device can be prevented from being increased. In addition, since the adhesive sheet is affixed to the adherend before it is launched, it can be affixed at the same affixing speed as a normal adhesive sheet, and the upright portion is raised as the adherend is conveyed. Since it is not necessary to stop the feeding for the process of starting up or bending the adhesive sheet, a series of sticking processes can be performed quickly. In addition, since the adhesive sheet is not folded in two, even if the base sheet is an adhesive sheet that is plastically deformed, it is possible to stand up by transporting the adherend while the upright portion is raised. The start-up state of the part can be maintained.

At this time, if the sheet sticking apparatus includes a displacement means for displacing the rising means, the rising means is positioned in an appropriate state according to the planar size, thickness, etc. of the adhesive sheet or adherend. It can be launched reliably.
Further, if the standing part is guided by the guide inclined end edge having a predetermined inclination, the standing part can be smoothly raised along with the conveyance of the adherend, and the adhesive sheet is damaged or displaced. Can be prevented. In particular, since the guide inclined end edge is inclined in a direction away from the adherend surface, the rising portion can be raised while being in contact with a predetermined position of the rising portion.

  The peeling means 3 includes a peeling plate 31 supported by the base frame 20 in a posture inclined to the lower left in FIG. 1, and the peeling plate 31 feeds the original fabric R guided from the side of the peeling sheet RL. The adhesive sheet S is peeled from the release sheet RL by having the release edge 32 positioned downstream in the direction X and bending the release sheet RL toward the drive roller 25 at the release edge 32.

  The pressing means 4 includes an elastically deformable pressing roller 41 such as rubber or resin, and the pressing roller 41 applies an adhesive sheet S that protrudes from the tip of the peeling plate 31 to the lower left in FIG. It is comprised so that it may press toward adherend surface AS.

  The rising means 5 includes a curved plate-like rising plate 51 that is supported by the displacing means 6 and extends along the conveying direction A. The rising plate 51 rises between the conveying means 7 and the adhesive sheet S. The rising tip 52 inserted between the rising portion 52 and the rising tip 52 is provided downstream from the rising tip 52 in the conveying direction A to guide the rising portion S2 in a rising direction away from the adherend surface AS. And a rising guide portion 53. Further, the rising plate 51 is inclined in a direction away from the adherend surface AS from the rising leading end portion 52 on the upstream side in the conveying direction A to the rising guide portion 53, and the guide inclined edge 54 that raises the rising portion S <b> 2. It is formed. The guide inclined edge 54 is formed to be inclined at a predetermined angle from the upright portion S2 side of the adhesive sheet S toward the adhesive portion S1 side in the plan view in the downstream view, as shown in FIGS. ), The upright portion S2 is gradually raised as the adherend W is transported, and can be raised from the adherend surface AS to a rising angle of approximately 90 °.

  As shown in FIG. 2, the displacement means 6 includes a shaft supporter 61 mounted above the rising plate 51, a shaft 62, and an articulated robot as a driving device that supports the shaft 62 on the opposite side of the shaft supporter 61. 63.

Examples of the articulated robot 63 include known 6-axis robots. Thereby, the shape of the adhesive sheet S, the dimensions along the A, B, and C directions, the angle at which the upright portion S2 rises upward from the adherend surface AS, the width, height, and length of the adherend W, etc. Accordingly, the posture and position of the rising plate 51 can be displaced.

  As a procedure for sticking the adhesive sheet S to the adherend W by the sheet sticking apparatus 1 described above, the peeling sheet RL and the adhesive sheet S are guided by the peeling plate 31 by feeding the raw fabric R by the feeding means 2. It is sent downstream in the feeding direction X. In this manner, the adhesive sheet S is fed to the tip end position of the release plate 31, and in the state where the adhesive sheet S is partially peeled from the release sheet RL turned back at the release edge 32, the feeding of the original fabric R is temporarily performed. Stop and enter standby mode. Next, when the adherend W conveyed by the conveying means 7 reaches a predetermined position below the pressing roller 41, it is detected by a sensor (not shown), and the feeding means 2 drives the rotating motor 25A to remove the original fabric R. It is fed out at the same speed as the conveyance speed of the adherend W, and the separation sheet RL is collected by the collection roller 27. As a result, the adhesive sheet S that has been stopped in a state where it is partially peeled off from the release sheet RL at the release edge 32 is peeled off from the release sheet RL, and the adhesive portion S1 is covered with the adherend W by the pressing roller 41. The adhesive sheet S is affixed to the adherend W in a state in which the upright portion S2 is protruded toward the intersecting surface W1 side of the adherend W as shown in FIG. When the adhesive sheet S is attached to the adherend W in this way, the unwinding operation of the original fabric R is stopped again and enters a standby state, and the same operation is repeated for the adherend W to be conveyed next. .

  Next, the adherend W to which the adhesive sheet S is adhered is transported in the transport direction A by the transport means 7, and as shown in FIG. Inserted on one surface side in S2, the rising tip 52 raises the rising portion S2 in a direction away from the adherend surface AS. At this time, the rising plate 51 gradually inclines upward from the upstream side in the transport direction A toward the downstream side, and inclines from the right side to the left side of the guide inclined edge 54 toward the downstream side in the transport direction A (gradually. The posture is maintained by the displacement means 6 so as to approach the intersection plane W1 side. In addition, the leading edge of the rising tip 52 is formed in a smooth arc shape, configured with a rotatable roller, a bearing, or the like, or configured with a member having a low frictional resistance such as a resin, Low friction means for reducing friction may be provided. In such a state, by conveying the adherend W together with the adhesive sheet S to the downstream side in the conveying direction A, the rising portion S2 becomes the guide inclined end edge of the rising guide portion 53 as shown in FIG. Stands along 54.

  Further, as shown in FIG. 3 (D), when the rising portion S2 rises from the adherence surface AS to the rising angle of about 90 ° along the guide inclined end edge 54, the rising is maintained with the rigidity of the base sheet BS. The portion S4 protrudes below the adherend surface AS, and the rising angle of the rising portion S2 is maintained by the rising maintaining portion S4 coming into contact with the intersecting surface W1 of the adherend W. Here, as shown in FIGS. 3B to 3D, the guide inclined end edge 54 has a predetermined position in the upright portion S <b> 2, that is, the upright portion S <b> 2 of the upright portion S <b> 2 from the upstream side in the transport direction A toward the downstream side. The upright portion S2 is raised and guided while being in contact with the position of the distance L from the right edge. This is because when the distance L is short, the rigidity of the base sheet BS cannot withstand the rising stress, and can be prevented from being bent at a position other than the folding line S3, and when the distance L is long, It is also possible to prevent the rising portion S2 from rising abruptly and causing the adhesive sheet S to be peeled off from the adherend surface AS, for example. The distance L can be appropriately changed depending on the configuration and properties of the adhesive sheet S, particularly the base sheet BS. When the adhesive sheet S is thus stuck to the adherend W and the upright portion S2 is raised, the adherend W to which the adhesive sheet S is stuck is transported to the next step, and thereafter the same operation is repeated. .

According to this embodiment, there are the following effects.
That is, since the standing portion S2 is raised after the adhesive sheet S is applied to the adherend W, the adhesive sheet S is displaced by folding in two before attaching the adhesive sheet S to the adherend W. Inconveniences such as sticking to the adherend W and clogging of the adhesive sheet S can be suppressed, and increasing the sticking speed can be handled without difficulty.
