Description

  The present invention relates to a sheet sticking apparatus and a sticking method, and more particularly to a sheet sticking apparatus and a sticking method capable of sticking at least two adhesive sheets to an adherend.

  Conventionally, a sheet sticking apparatus for sticking an adhesive sheet such as a label to an adherend has been widely used, and such a sheet sticking apparatus is disclosed in Patent Document 1, for example. The sheet sticking device of Patent Document 1 includes a transport unit that transports an adherend, and two pasting machines that are juxtaposed in the transport direction of the transport unit and can paste an adhesive sheet, and transports the adherend. In the middle of conveying from the upstream side in the conveying direction of the means, after sticking the first adhesive sheet to the adherend with the pasting machine on the upstream side in the conveying direction, the adherend is further conveyed downstream, It is comprised so that the 2nd adhesive sheet may be stuck with the sticking machine of the conveyance direction downstream.

JP 2007-153346 A JP 2009-67441 A

  However, in the sheet sticking device of Patent Document 1, the supply position for supplying the adherend is on the upstream side in the transport direction, whereas the discharge position of the adherend to which the adhesive sheet is pasted is on the downstream side in the transport direction. In such a configuration, a supply device that supplies the adherend to the supply position and a discharge device that discharges the adherend from the discharge position must be provided separately, including peripheral devices such as the supply device and the discharge device. There is an inconvenience that the equipment becomes larger and the structure becomes complicated. Here, by using a transfer device such as an articulated robot, both the supply and the transport of the adherend can be performed with a single supply device and discharge device. In this case, the transfer device itself is covered. The moving distance for supplying and discharging the adherend becomes long, and a large transfer apparatus must be adopted, and the size of the equipment including peripheral devices is inevitable.

  Further, in the sheet sticking device of the cited document 2, the first adhesive sheet and the second adhesive sheet are stuck respectively, so that the cylinder is operated by pressing means to press the first adhesive sheet against the adherend, and the second adhesive sheet Three operations are indispensable: an operation of returning to the position where the adhesive is held by suction and an operation of pressing the second adhesive sheet against the adherend. For this reason, in the sheet sticking apparatus of the same literature, the inconvenience that the sticking capability which sticks an adhesive sheet per unit time becomes low arises.

[Object of invention]
An object of the present invention is to provide a sheet pasting apparatus that can prevent the equipment including peripheral devices from becoming large and complicated, and can improve the pasting ability of pasting a plurality of adhesive sheets per unit time. It is to provide a sticking method.

In order to achieve the above-mentioned object, the present invention provides a first paste for feeding a first adhesive sheet in a first feeding direction and pressing the first adhesive sheet on an adherend surface of an adherend at a first pressing position. Means,
A second pasting means for feeding the second adhesive sheet in the second feeding direction and pressing the second adhesive sheet against the adherend surface of the adherend at a second pressing position;
A sheet sticking device comprising a moving means for relatively moving the first and second sticking means and the adherend,
The moving means is provided such that the relative movement is possible in a forward direction and a return direction opposite to the forward direction.
The first sticking means presses the first adhesive sheet against the adherend surface via the pressing means 42R while feeding the first adhesive sheet when the moving means performs the relative movement in the forward direction. Pasted
When the moving means performs the relative movement in the backward direction, the second sticking means feeds the second adhesive sheet through the pressing means 42L while feeding the second adhesive sheet. The structure of pressing and sticking to is adopted.

  In the present invention, the first and second sticking means may be configured such that the first feeding direction and the second feeding direction are mutually in a side view from an orthogonal direction that is parallel to the adherend surface and orthogonal to the relative movement direction. You may take the structure that it is set as the opposing arrangement | positioning which approaches.

  Furthermore, a configuration in which a width direction adjusting unit capable of relatively moving the adherend and the first pasting unit or the second pasting unit in the orthogonal direction is also preferably employed.

Further, in the sticking method of the present invention, when the first sticking means and the adherend move relative to each other in the forward direction, the first sticking means feeds the first adhesive sheet in the first feeding direction while the first sticking means and the adherend move relative to each other. A process of pressing and sticking the adhesive sheet to the adherend surface of the adherend at the first pressing position via the pressing means 42R ;
When the second sticking means and the adherend is relatively moved in the backward direction is a reverse direction of the forward path, while feeding the second adhesive sheet in a second feeding direction in the second bonding means, the second adhesive sheet And the step of pressing and adhering to the adherend surface of the adherend at the second press position via the pressing means 42L .

  According to the present invention, after the adherend is relatively moved in the forward direction and the first adhesive sheet is pasted, the relative movement is performed in the backward direction and the second adhesive sheet is pasted. The discharge position of the adherend to which each adhesive sheet is affixed can be made the same position. As a result, the supply and discharge of the adherend can be performed by the same transfer device, and the equipment including peripheral devices becomes larger and more complicated than when transfer devices different for supply and discharge are used. This can be prevented. In addition, the supply position and the discharge position of the adherend are different, and the moving distance of the transfer device can be shortened compared to a case where the transfer device is a single one, which also enlarges the equipment, It is possible to prevent complication. Further, the first and second adhesive sheets can be attached by two operations, ie, a relative movement operation in the forward path by the moving means and a relative movement operation in the return path, and a plurality of adhesive sheets are pasted per unit time. Capability can be improved.

  Further, in the side view, the first and second sticking means can be brought close to each other in the first feeding direction and the second feeding direction so that the first and second pressing positions can be brought closer, It is possible to shorten the relative movement distance for sticking each of the first and second adhesive sheets to the adherend and further improve the sticking ability of sticking the adhesive sheet per unit time.

  Furthermore, when it has a width direction adjustment means, the variation of the position which affixes an adhesive sheet on a to-be-adhered surface can be increased.

The lowest position of the pressing roller 42R is the first pressing position PP1.

  The second sticking means SM2 is different from the first sticking means SM1 in that the support shaft 34L supports the second original fabric RS2 in which the second adhesive sheet AS2 is temporarily attached to the second release sheet RL2. Is equivalent to the first sticking means SM1, and is arranged symmetrically with the first sticking means SM1 with respect to a plane parallel to the YZ plane. Accordingly, the first and second sticking means SM1 and SM2 are disposed opposite to each other so that the first feeding direction FD1 and the second feeding direction FD2 approach each other in a side view from the orthogonal direction (view from the Y-axis direction). It is said that. Therefore, since it can be understood by replacing R at the end of the numbering of the first sticking means SM1 as L, detailed description will be omitted.

The position in the axial direction and the position in the Y-axis direction of the adherend WK are provided so as to be detectable.

  Next, a method for attaching the first and second adhesive sheets AS1 and AS2 according to the embodiment will be described.

  First, as shown in FIG. 1, the first and second original fabrics RS1 and RS2 are set in the first and second sticking means SM1 and SM2, respectively. Next, the width direction adjusting means 17 drives the linear motion motors 46R and 46L so that the pasting positions in the Y-axis direction of the first and second adhesive sheets AS1 and AS2 on the adherend surface WK1 are a predetermined position. Each of the first and second sticking means SM1, SM2 is moved in the Y-axis direction. At this time, the linear motors 46R and 46L can be driven by an operator via a manual switch (not shown) or automatically moved to a predetermined position. Accordingly, the adhesive sheets AS1 and AS2 can be attached to arbitrary positions in the Y-axis direction of the adherend surface WK1 (see FIGS. 2A to 2D). Next, when an automatic operation command is input by an operation switch (not shown), the first and second pasting means SM1 and SM2 drive the rotation motors DM2R and DM2L, and the first and second original fabrics RS1 and RS2 are moved. Pull out. When the leading ends of the first and second adhesive sheets AS1 and AS2 are peeled by a predetermined length from the leading ends of the peeling plates 35R and 35L by this feeding, and the leading ends are detected by a sensor (not shown), the first and second stickers are attached. The means SM1, SM2 stop driving the rotation motors DM2R, DM2L and enter a standby state.

  When the transfer device (not shown) places the adherend WK at the transfer position, the height direction adjusting means 16 drives the linear motion motors 44R and 44L, and the first and second sticking means SM1 and SM2 are set to Z. Move in the axial direction. At this time, the input means 27 detects the position of the adherend surface WK1 in the Z-axis direction. In the case of the present embodiment, when the input means 27 is composed of a reflection type optical sensor, the input means 27 rises from the lowest position of the adherend WK while emitting light, and there is no longer any reflection of the emitted light. Then, the drive of the linear motor 44R is stopped, and the storage means (not shown) stores the position of the adherend surface WK1 in the Z-axis direction. As a result, the height direction adjusting means 16 is positioned slightly below the adherend surface WK1 based on the position recognition of the first adherend surface WK1 by the input means 27, and the appropriate pressure is applied by the pressure roller 42R. The first sticking means SM1 is moved to a position where the first adhesive sheet AS1 can be applied to the adherend surface WK1 by pressure. The height direction adjusting means 16 drives the linear motion motor 44L even after the linear motion motor 44R stops, and the second pressing position PP2 is slightly above the adherend surface WK1, and the second is pressed by the pressing roller 42L. The second pasting means SM2 is moved to a position where the adhesive sheet AS2 is not pressed against the adherend surface WK1.

  Next, the moving means 11 drives the rotation motor DM1 to rotate the belt 32 to move the adherend WK in the forward direction. Then, when the adherend WK is detected by a sensor (not shown), the first pasting means SM1 drives the rotation motor DM2R to feed out the first original fabric RS1 in accordance with the conveyance speed of the adherend WK, and the peeling plate While the first adhesive sheet AS1 is peeled from the first release sheet RL1 with 35R, the first release sheet RL1 is pressed against the adherend surface WK1 with the pressing roller 42R and pasted.

  When it is detected by a sensor (not shown) that the right end of the adherend WK to which the first adhesive sheet AS1 has been past has passed under the peeling plate 35L, the moving means 11 stops the rotation motor DM1, The movement of the landing body WK in the forward direction is stopped. Next, the height direction adjusting means 16 drives the linear motion motors 44R and 44L, and the first and second sticking means SM1 and SM2 are set based on the position in the Z-axis direction of the adherend surface WK1 stored in the storage means (not shown). Move in the Z-axis direction. As a result, the first pressing position PP1 is slightly above the adherend surface WK1, and the first sticking means SM1 moves to a position where the first adhesive sheet AS1 fed next by the pressing roller 42R is not pressed against the adherend surface WK1. To do. Further, the second pressing position PP2 is slightly below the adherend surface WK1, and the second sticking means SM2 is moved to a position where the second adhesive sheet AS2 can be applied to the adherend surface WK1 with an appropriate pressing force by the pressing roller 42L. To do.

  Next, the moving means 11 drives the rotation motor DM1 to rotate the belt 32 to move the adherend WK in the backward direction. When the adherend WK is detected by a sensor (not shown), the second pasting means SM2 drives the rotation motor DM2L to feed out the second original fabric RS2 in accordance with the conveyance speed of the adherend WK, and the peeling plate. While the second adhesive sheet AS2 is peeled from the second release sheet RL2 at 35L, the second release sheet RL2 is pressed against the adherend surface WK1 by the pressing roller 42L and pasted. Thereafter, when the adherend WK to which the first and second adhesive sheets AS1 and AS2 have been attached reaches the transfer position, it is detected by a detection means (not shown), and the movement means 11 stops the rotation motor DM1, The landing body WK is discharged by a transfer device (not shown).

  Here, the attaching positions of the first and second adhesive sheets AS1 and AS2 on the adherend surface WK1 have various variations by changing their attaching positions and sizes in the X-axis and Y-axis directions. ) To (D) can be exemplified. In FIG. 5A, the first adhesive sheet AS1 is smaller in size than the second adhesive sheet AS2, and after the first adhesive sheet AS1 is pasted by the first sticking means SM1, the first adhesive sheet AS2 is put by the second sticking means SM2. The second adhesive sheet AS2 is pasted so as to cover the entire AS1. In FIG. 5B, after the first adhesive sheet AS1 is pasted in the same manner as described above, the second adhesive sheet AS2 is pasted so as to cover a part of the first adhesive sheet AS1 in the X-axis direction. In FIG. 6C, after the first adhesive sheet AS1 is pasted in the same manner as described above, the second adhesive sheet AS1 is not adjacently covered with the second adhesive sheet AS1 in a position adjacent to the first adhesive sheet AS1. Adhesive sheet AS2 is affixed. In FIG. 4D, the first and second adhesive sheets AS1 and AS2 have the same shape, and in the same manner as described above, after the first adhesive sheet AS1 is pasted, the first adhesive sheet AS1 is entirely covered. 2 Adhesive sheet AS2 is affixed. These pasting variations can be determined by the width direction adjusting means 17.

  Therefore, according to such an embodiment, the supply position of the adherend WK and the discharge position of the adherend WK to which the adhesive sheets AS1 and AS2 are attached can be set to the same position. As a result, the supply and discharge of the adherend WK can be performed by the same transfer device, and the equipment including peripheral devices is enlarged and complicated compared to the case of using different transfer devices for supply and discharge. Can be prevented. In addition, the supply position and the discharge position of the adherend WK are different, and the operation distance of the transfer device can be shortened compared with the case where the transfer device is a single one, which also increases the size of the equipment. It is possible to prevent complication. Furthermore, the first and second adhesive sheets AS1 and AS2 can be attached by two operations of a relative movement operation on the forward path and a relative movement operation on the return path by the moving means 11, and a plurality of adhesive sheets can be attached per unit time. It becomes possible to improve the pasting ability to stick. In addition, since the first and second pressing positions are arranged opposite to each other in the X-axis direction, the movement of the adherend WK by the moving unit 11 from the first adhesive sheet AS1 to the second adhesive sheet AS2 is applied. The distance can be shortened, and the pasting ability can be further enhanced.
