Description

The present invention relates to a sheet sticking equipment pasting the sheet on the upper surface of the pasting target body.

  Conventionally, a long sheet is pressed against the upper surface of the adherend with a roller by passing a table on which the adherend is placed while sliding under a roller disposed at a predetermined position. Various configurations for pasting have been proposed (Patent Documents 1 and 2 below).

  However, when the table is configured to reciprocate within a predetermined section, the apparatus is complicated because the predetermined section needs to be returned to the original position. That is, the cylinder described in Patent Document 1 described below requires a return cylinder, and the one described in Patent Document 2 described below requires reverse rotation control of the motor. In addition, the next pasting cannot be performed without returning to the original position, and the pasting cannot be performed efficiently.

Japanese Utility Model Publication No. 4-40922 JP 2005-297458 A

Therefore the present invention has been made in view of the above problems, and an object thereof is to provide a sheet sticking equipment that can be attached easily and efficiently bonding the sheet to the upper surface of the pasting target body.

The present invention has been made to solve the above problems, and the sheet sticking device according to the present invention is a sheet sticking device for sticking an adhesive sheet having an adhesive layer on one side to a sheet-like adherend. There is an apparatus main body having a pressing member and a table on which the adherend is placed, and the table on which the adherend is placed passes while sliding below the pressing member, In the sheet sticking apparatus in which the pressing member presses and adheres the long adhesive sheet to the upper surface of the adherend, the apparatus main body is provided with a guide rail for sliding the table, is removable from the apparatus body at a downstream side of and the pressing member can be mounted to the apparatus body at the upstream side, and a table provided with two or more units, extended Te overall length than the table is shorter Further comprising a table, characterized in that the extension table, and a possible separation piece detachable extension table body and the extension table body, the upper surface of the separating piece which constitutes the front side of the predetermined region of the upper surface of the extension table And

  In the sheet sticking device having such a configuration, the table is mounted at a position on the upstream side of the pressing member in the device main body, but the adherend may be placed in advance on the mounting table, The adherend may be placed on the table after being mounted on the apparatus main body. In any case, the table on which the adherend is placed is slid along the guide rail to pass below the pressing member. When the table passes under the pressing member, the long sheet is pressed and pasted to the adherend by the pressing member. And when the table passes the pressing member, since the long sheet is already pasted on the adherend, the long sheet is cut off from the long sheet on the downstream side of the pressing member. The table is separated, and the table is removed from the apparatus main body at a position downstream of the pressing member.

  In particular, since two or more tables are provided, the first table passes under the pressing member and then passes through the second table, so that the adherend on each table is long. A scale-like sheet can be continuously pasted. Furthermore, for example, when there are two tables, the first table removed from the apparatus main body is mounted again at the upstream position of the apparatus main body when the second table passes under the pressing member. Then, slide the first table after the second table. Similarly, the second table is detached from the apparatus main body, is mounted on the upstream side again, and continues after the first table. Thus, by attaching and using the table removed from the apparatus main body at the upstream position again, it is possible to continuously perform the attachment to three or more adherends with two tables. The same applies to the case where three or more tables are provided, and the table is sequentially mounted at a position upstream of the pressing member and continuously passed under the pressing member, so that a plurality of adherends are elongated. Sheets can be stuck continuously. In addition, when a sheet is attached to the same number of adherends when three or more tables are provided, all the tables can be continuously slid and pasted. The pasting process can be performed by repeatedly using only two of the tables.

Further, an extension table having a shorter overall length than the table is further provided . When joining the adhesive sheet having an adhesive layer on one surface in a sheet-like such a thin pasting target body, the start portion for sticking the first adhesive sheet pasting target body is important. That is, when the front end of the pressure-sensitive adhesive sheet is directly attached to the adherend, it is easy for wrinkles to enter the pressure-sensitive adhesive sheet at the start of application, or air bubbles to enter between the pressure-sensitive adhesive sheet and the adherend. Therefore, it is preferable to stick a pressure-sensitive adhesive sheet to the first adherend after continuing to stick a pressure-sensitive adhesive sheet to a certain section as a running section. Therefore, by placing an extension table on the front side of the first table and attaching the adhesive sheet to the upper surface of the extension table as a running section, the adhesive sheet to be attached to the adherend of the first table Wrinkles and bubbles are less likely to occur. Moreover, an extension table can be used also when the sticking process to several to-be-adhered bodies is complete | finished. That is, if the adhesive sheet is pasted on the upper surface of the extension table by sliding the extension table after the table on which the last adherend is placed, the next time is passed. When the predetermined number of pasting steps are started, the work of pasting the tip of the adhesive sheet to the extension table again becomes unnecessary, and the next pasting step can be started quickly.

Furthermore, the extension table is provided with a detachable separation pieces extend the table body and the extension table body, the upper surface of the isolation piece that make up the front side of the predetermined region of the upper surface of the extension table. The front side means the downstream side, and the rear side means the upstream side. As described above, when the extension table is slid after the last table and the adhesive sheet is attached to the extension table to finish the predetermined number of attaching steps, the separation piece is removed from the extension table body after the attaching step. By separating, the front end of the pressure-sensitive adhesive sheet can be attached to the separation piece until the next attaching step. In general the adhesive layer of the adhesive sheet is covered with a release paper, but will be gradually stuck to pasting target body while peeling off the release paper, until the next predetermined number of attaching process, the pressure-sensitive adhesive sheet It is not preferable that the adhesive layer is exposed for a long time. Therefore, it is preferable to store the release paper on the exposed adhesive layer part again, but at that time, the adhesive sheet is attached only to the separation piece, not the entire extension table. It is easy to handle compared to a configuration that is not provided. Therefore, it can be easily performed because only the separation piece is used to store the peeled release paper again on the adhesive sheet. The storage operation of the adhesive sheet becomes easy.

In addition, a sheet sticking method using this sheet sticking apparatus is such that a long sheet is pressed with a pressing member on the upper surface of an adherend placed on a table and the table is moved in that state. A sheet sticking method for sticking a sheet to a sticking body, in which two or more tables are sequentially set at a position upstream of the moving path, and are slid along the moving path to continuously pass under the pressing member. By sticking a long sheet continuously to the adherend of each table by cutting the long sheet on the downstream side of the pressing member, the table that has passed the pressing member is removed from the moving path. It is characterized by removing sequentially. In addition, when removing the adherend with a sheet from the table, it is necessary to first remove the adherend with the sheet from the table in the movement path and then remove the table from the movement path. You may remove the to-be-adhered body with a sheet | seat from the table after removing.

  In this method, two or more tables are sequentially set on the movement path and are continuously slid to stick a long sheet on the adherend, so that one stick It is not necessary to return the table to the upstream side of the pressing member along the movement path every time a long sheet is attached to the body.

  In particular, it is preferable to use the table removed from the movement path by setting it again at a position upstream of the movement path. It is possible to use as many tables as the number of adherends to be pasted in a single pasting process, but by setting the table removed from the travel path to the position upstream of the travel path and using it again The pasting process can be performed with a small number of tables.

  In particular, it is preferable that the sheet is continuously pasted to three or more adherends with two tables. The minimum number of tables is two, and the table storage space is small.

  On the other hand, it is preferable that the table is manually pushed from the upstream side of the pressing member to slide and the downstream table is pushed by the upstream table. By manually sliding the table, no power is required. In addition, when the table is manually slid, the pressing member can be pulled from the downstream side, but by pressing from the upstream side of the pressing member, the table is slid while visually checking the state of attachment to the adherend. Can be moved. In addition, by pushing the downstream table with the upstream table, the upstream table can be easily slid to the downstream side of the pressing member, and the long sheet is covered with the upstream table. It can be applied smoothly and continuously to the sticking body.

  Further, in the case where an adhesive sheet having an adhesive layer on one side is attached to a sheet-like adherend, the adherend is placed at a position spaced rearward from the front end of the table, and the upper surface of the table is pressed by a pressing member. It is preferable that the pressure-sensitive adhesive sheet is attached to the adherend after the pressure-sensitive adhesive sheet is attached to the front side of the substrate. In this way, by sticking the adhesive sheet to the front section of the upper surface of the table, the front part of the adherend placed on the table is securely fixed to the table with the adhesive sheet, and then the adhesive sheet is attached. I can go.

  It is also preferable to place a separate extension table on the front side of the first table. Since the adhesive sheet is to be attached to the extension table, the distance from the tip of the adhesive sheet to the front end of the adherend on the first table is the adherend on the upper surface from the front end of the second table. Longer than the distance to the front edge of That is, the run-up section until the adhesive sheet is applied to the first adherend is lengthened, and the adhesive state of the adhesive sheet can be stabilized. An adhesive sheet can be reliably affixed in a sticking body.

  Similarly, it is also preferable to lengthen the run-up section by using a longer table than the second table as the first table, and to suppress generation of wrinkles and bubbles in the first adherend. .

  As described above, in the sheet sticking apparatus according to the present invention, the table is configured to be attachable to the apparatus main body on the upstream side of the pressing member and to be removable from the apparatus main body on the downstream side of the pressing member. The table removed from the main body can be used again by being attached to the apparatus main body on the upstream side of the pressing member. Therefore, it is not necessary to return the table from the downstream side to the upstream side of the pressing member along the guide rail, and the structure of the apparatus is simplified as compared with the structure in which the table is returned to the upstream side along the guide rail. be able to. In addition, since two or more tables can be continuously slid to perform continuous pasting, the tables can be pasted more efficiently than a configuration in which the tables are reciprocated.

  Hereinafter, a sheet sticking apparatus and a sheet sticking method according to an embodiment of the present invention will be described with reference to FIGS. The sheet sticking apparatus in the present embodiment places a sheet-like adherend 80 on the table 2 and slides the table 2 along the guide rail 11 so that the lower side of the pressing roller 3 as a pressing member is placed. The long pressure-sensitive adhesive sheet 90 is pasted on the upper surface of the adherend 80 by the pressing roller 3, and is extended with the apparatus main body 1 and the two tables 2 (tables 21 and 22). Table 4 is provided. Details will be described below.

  Note that an arrow A in the figure indicates a traveling direction when the table 2 is slid. Further, the upstream side in the traveling direction is referred to as the rear, and the downstream side is referred to as the front.

  1 and 2 show a state in which the table 2 on which the adherend 80 is placed passes under the pressing roller 3 of the apparatus main body 1. However, hatching indicating a cross section is omitted in FIG. The apparatus main body 1 includes a plate-like base 10. The base 10 has a rectangular shape that is long in the direction of travel, and the table 2 is placed on the upper surface of the base 10, and the upper surface serves as a support surface that supports the table 2 so that the table 2 slides. Move to slide. A pair of left and right guide rails 11 are attached to the upper surface of the base 10 in the traveling direction. The table 2 slides between the two guide rails 11 as a movement path. Therefore, each inner surface 11 a of both guide rails 11 serves as a guide surface of the table 2. The guide rail 11 is provided from the position away from the rear end 10 b of the base 10 by a predetermined distance in the traveling direction toward the traveling direction and reaches the front end 10 a of the base 10. That is, there is a space where the guide rail 11 is not provided at the rear portion (upstream side) of the base 10. In other words, the upper surface of the base 10 on which the table 2 is placed extends rearward from the rear end 11 c of the guide rail 11. The length of the extension is at least a length that allows the table 2 to be placed on the extension portion, that is, the extension portion is longer than the length of the table 2 or shorter than the length of the table 2. However, the length is such that the front side of the table 2 can be placed without lifting, and in this embodiment, the length is slightly shorter than the length of the table 2.

  In addition, plate-like support walls 12 are attached to the outer surfaces of both guide rails 11, and the pressing roller 3 is rotatably supported by the pair of support walls 12. The pressing roller 3 extends in a direction orthogonal to the traveling direction, and is provided horizontally so that the distance from the upper surface of the base 10 is substantially constant. Specifically, the pressing roller 3 includes a shaft portion 3a and a cylindrical pressing portion 3b attached to the outer peripheral surface of the shaft portion 3a. The shaft portion 3a is a bearing (not shown) on the support wall 12. Is supported through. A notch 11b is formed on the upper surface of the guide rail 11, and the shaft 3a of the pressing roller 3 is located in the notch 11b. Moreover, the cylindrical pressing part 3b is comprised from the member which has cushioning properties, and has the full length longer than the width | variety of the largest to-be-adhered body 80 mounted in the table 2, The table mentioned later It is slightly longer than the width of the two thin plates 26. The cylindrical pressing part 3b presses the long adhesive sheet 90 against the adherend 80, and the height of the pressing part 3b with respect to the upper surface of the base 10 is as shown in FIG. When passing below the pressing portion 3b, the pressing portion 3b is set to be compressed about several mm in the radial direction.

  Further, a sheet roll 91 around which a pressure-sensitive adhesive sheet 90 with release paper is wound is mounted on the upper part of the pair of support walls 12 as shown in FIG. The sheet roll 91 is wound in a roll shape with the release paper 92 as an inner surface, and is attached to the supply shaft 13. As an example, a sheet roll 91 having a lateral width of A4 size can be used, but in any case, the sheet roll 91 having a shorter distance than the distance between the support walls 12 is used. Therefore, as shown by a two-dot chain line in FIG. 1, in order to restrict one end surface of the sheet roll 91, specifically, the left end surface with respect to the traveling direction, the supply shaft 13 has a disk as a flange. 14 is attached. Although the other end face is not restricted by the disk and is in a free state, a disk may be provided on the other side to restrict the position.

  An intermediate shaft 15 and a take-up shaft 16 are rotatably supported below the supply shaft 13, and the adhesive sheet 90 with release paper pulled out from the sheet roll 91 is separated from the release paper on the intermediate shaft 15. 92 is separated, and the separated release paper 92 is wound around the take-up shaft 16, while the adhesive sheet 90 from which the release paper 92 has been peeled travels toward the pressing roller 3 located below the intermediate shaft 15. The take-up shaft 16 is provided at a position higher than the intermediate shaft 15, and therefore there is no other component between the intermediate shaft 15 and the pressing roller 3. The operation of rotating the supply shaft 13 to pull out the pressure-sensitive adhesive sheet 90 with release paper or rotating the take-up shaft 16 to wind up the release paper 92 is performed manually. At this time, since the disk 14 has a large diameter, the supply shaft 13 can be easily rotated by rotating the disk 14. Further, since the belt 17 is wound around the shafts 13 and 16 so that the supply shaft 13 and the winding shaft 16 are interlocked, the release paper 92 is wound around the winding shaft 16 by rotating the supply shaft 13. Can be taken. However, since the release paper 92 wound around the winding shaft 16 is removed every time a predetermined number of pasting steps are completed, the diameter of the sheet roll 91 is always larger than the diameter on the winding shaft 16 side. When the supply shaft 13 is rotated, the drawing length from the sheet roll 91 is longer than the winding amount of the winding shaft 16, and the release paper 92 is moved between the intermediate shaft 15 and the winding shaft 16. The release paper 92 between the intermediate shaft 15 and the take-up shaft 16 is positioned upward from the base 10, but there is no problem.

  The pressure-sensitive adhesive sheet 90 has a pressure-sensitive adhesive layer on one side, and as the pressure-sensitive adhesive sheet 90, various plastic sheets (plastic films) having flexibility can be used. Further, as the sheet-like adherend 80, there are single-layer and multi-layer sheets made of paper or plastic, and in particular, those having characters and designs printed on the surface are suitable, and the printed surface is protected. It is preferable to laminate a transparent or translucent adhesive sheet 90. Among them, in particular, if a transparent or translucent adhesive sheet 90 is laminated on a sheet of paper or plastic on which a large number of business card symbols are printed, and the printed surface is protected, a multilayer business card can be easily created. it can. Furthermore, if a transparent or translucent adhesive sheet 90 is laminated on a transparent sheet on which business card notation is printed, a transparent business card can be created as a whole.

  Thus, the pressure roller 3, the supply shaft 13, the intermediate shaft 15, and the take-up shaft 16 are positioned above the base 10, and the supply shaft 13, the intermediate shaft 15, and the take-up shaft 16 are All are located on the upstream side (rear side) of the pressing roller 3. Accordingly, the upper side of the base 10 is opened on the downstream side of the pressing roller 3. Conversely, the supply shaft 13 and the like exist on the upstream side of the pressing roller 3, but as described above, the upper surface of the base 10 extends a predetermined length upstream from the guide rail 11. The upper part of the extended part of the base 10 is open. Therefore, on the upstream side of the pressing roller 3, the table 2 can be placed on the extended portion of the upper surface of the base 10 from above, and on the downstream side of the pressing roller 3, the table 2 is moved upward from the upper surface of the base 10. Can be detached and removed. Since the front end 10a of the base 10 is not provided with a stopper or the like and the guide rails 11 are open to the front, the table 2 can also be removed by sliding it forward from the base 10.

  In this way, the table 2 is mounted so as to be placed on the base 10 on the upstream side of the pressing roller 3, and is removed so as to separate upward or forward from the base 10 on the downstream side of the pressing roller 3. That is, the table 2 is configured separately from the apparatus main body 1 and can be attached to and detached from the apparatus main body 1. In the present embodiment, two tables 2 are provided.

  Specifically, the table 2 has a rectangular plate shape in plan view as shown in FIG. The table 2 has a rectangular shape in which the length in the traveling direction is longer than the length in the direction orthogonal to the traveling direction (length in the width direction). The table 2 is composed of a main plate 25 and a thin plate 26 bonded to the upper surface of the main plate 25 and thinner than the main plate 25, and the upper surface of the table 2 is composed of the upper surface of the thin plate 26. That is, the upper surface of the thin plate 26 is a mounting surface on which the adherend 80 is mounted. The thin plate 26 has the same length in the traveling direction as the main plate 25, but is shorter in the width direction than the main plate 25. Therefore, as shown in FIG. 3, non-mounting regions 27 and 28 are formed on both sides of the upper surface of the table 2 where the thin plate 26 does not exist. The placement area 27 is formed wider than the left non-placement area 28. As shown in FIG. 4, the adherend 80 is placed on the upper surface of the thin plate 26. At this time, the left side of the adherend 80 is placed on the left edge 26 a of the thin plate 26 in the traveling direction. Align the edges of. That is, the left edge 26 a of the thin plate 26 serves as a mark indicating the position in the width direction when the adherend 80 is placed, and a step is formed between the thin plate 26 and the main plate 25. Therefore, the left edge of the adherend 80 can be aligned with the left edge 26a of the thin plate 26 in the traveling direction while feeling the level difference with the fingertip.

  In addition, the front end 80a of the adherend 80 is displaced from the front end 2a of the table 2 to a rear by a predetermined length (for example, 20 mm to 30 mm). In addition, in FIG. 4, the case where the adherend 80 of A4 size is used is shown, Therefore, the table 2 is formed in the magnitude | size which can mount the adherend 80 of A4 size, Usually, the thin plate 26 is a size larger than the A4 size. Moreover, when using the sheet | seat which has the above printing surfaces as the to-be-adhered body 80, a certain margin part is provided in the outer side of the effective printing area | region 81 shown with a dashed-two dotted line in FIG. It is preferable to cut off the blank portion after completion of the sticking. In that case, an adhesive sheet 90 (shown by a two-dot chain line in FIG. 4) having the same width as the adherend 80 can be used. However, the size of the adherend 80 placed on the table 2 is arbitrary. For example, in the case of the table 2 on which the A4 size adherend 80 can be placed, the A4 size or less is arbitrary. A to-be-adhered body 80 having a size and shape can be placed.

  The main plate 25 can be made of an appropriate material such as metal, plastic or wood, and the thin plate 26 can be made of the same material. However, the material of the thin plate 26 is particularly preferably plastic such as acrylic from the viewpoint of weight reduction and durability, and it is preferable that the upper surface is rough and the peelability of the adhesive sheet 90 is good.

  Further, an extension table 4 is provided in addition to the two tables 2 (tables 21 and 22). The extension table 4 is used at the start and end of the sticking step of sticking the adhesive sheet 90 to a predetermined number of adherends 80. Although a specific method of use will be described later, as shown in FIG. 5, the extension table 4 is formed with the same thickness and the same width as the table 2, while the length in the traveling direction (full length) is longer than that of the table 2. It is short, for example, about 60 mm. The extension table 4 includes an extension table body 40 and a separation piece 45 that is configured separately from the extension table body 40 and can be attached to and detached from the extension table body 40. Similar to the table 2, the extension table main body 40 includes a main plate 41 and a thin plate 42 that is bonded to the upper rear portion of the main plate 41 and is thinner than the main plate 41. The thin plate 42 is shorter than the main plate 41 in the width direction, and has the same width as the thin plate 26 of the table 2 described above. And it fixes to the upper surface rear part of the main board 41 so that the position of the thin plate 26 of the table 2 and the width direction may be aligned, and the thin board 42 has reached the rear end of the main board 41. The main plate 41 and the thin plate 42 can be made of the same material as that of the table 2. In particular, the same material is preferably used, and the upper surface of the thin plate 42 is preferably similarly rough.

  On the other hand, the separation piece 45 is positioned on the front side of the thin plate 42 and constitutes a predetermined region on the front side of the upper surface of the extension table 4. That is, the separation piece 45 is mounted so as to be placed on the upper front portion of the main plate 41, and the upper surface thereof is flush with the upper surface of the thin plate 42, and constitutes the upper surface of the extension table 4 together with the upper surface of the thin plate 42. To do. Specifically, the separation piece 45 includes a horizontal plate portion 46 placed on the front upper surface of the main plate 41 and a vertical plate portion 47 that is bent and extended perpendicularly downward from the front end of the horizontal plate portion 46. As a whole, it is formed in an L shape in sectional view. The lower end of the vertical plate portion 47 is positioned flush with or slightly above the lower surface of the main plate 41. The horizontal plate portion 46 and the vertical plate portion 47 are formed to have the same width. The upper surface of the horizontal plate portion 46 is the upper surface of the separation piece 45, and the vertical plate portion 47 extends in contact with the front surface of the main plate 41. The front surface of the table 4 is configured. The separation piece 45 is formed to have the same width as the extension table body 40 and is guided by the guide rail 11 together with the extension table body 40. As for the material of the separation piece 45, metal, plastic, wood or the like can be used, but metal such as aluminum or plastic is particularly preferable from the viewpoint of durability. Moreover, it is preferable to form the upper surface of the horizontal plate part 46 into a rough surface.

  Next, a procedure for sticking the long adhesive sheet 90 to the adherend 80 using the sheet sticking apparatus configured as described above will be described. In addition, the case where the sheet | seat printed with the margin part on either side as shown in FIG. 4 is used as the to-be-adhered body 80, and the sheet roll 91 of the same width as the to-be-adhered body 80 is used is demonstrated. However, the width of the pressure-sensitive adhesive sheet 90 may vary, the right and left edge portions 26a of the pressure-sensitive adhesive sheet 90 may have undulations, and the pressure-sensitive adhesive sheet 90 is slightly left and right with respect to the adherend 80. If the pressure sensitive adhesive sheet 90 needs to be accurately applied to the entire width of the adherend 80, the sheet roll 91 wider than the adherend 80 is used. use.

  First, perforation is made in advance along the width direction at a location of, for example, about 25 mm from the tip of the release paper 92 of the sheet roll 91. The sheet roll 91 is mounted on the supply shaft 13 and the adhesive sheet 90 with release paper is pulled out to the front side (downstream side) through the lower side of the pressing roller 3. Then, as shown in FIG. 7, while the extension table 4 is placed on the upper surface of the base 10 on the downstream side of the pressing roller 3, the leading end portion of the release paper 92 is peeled off as shown in FIG. The tip portion of the adhesive sheet 90 is pasted on the upper surface of the separation piece 45. FIG. 7 shows a state where the exposed tip portion of the adhesive sheet 90 is attached to the upper surface of the separation piece 45. Note that the leading end portion of the release paper 92 may be cut with a perforation. In addition, illustration of the guide rail 11 is abbreviate | omitted in FIG.

  After the front end portion of the adhesive sheet 90 is attached to the upper surface of the separation piece 45, the separation piece 45 is separated from the extension table main body 40. The extension table main body 40 is removed from the base 10 and brought to the upstream side of the pressure roller 3 and placed on the upper surface of the base 10, while the separation piece 45 passes upstream of the pressure roller 3 together with the adhesive sheet 90 in the reverse direction. The extension table main body 40 and the separating piece 45 are combined on the upstream side of the pressing roller 3 as shown in FIG. The release paper 92 is peeled off from the adhesive sheet 90 by a predetermined length, and the leading end portion of the release paper 92 is fixed to the take-up shaft 16 and wound.

  Then, the first table 21 is set on the upstream side of the extension table 4. At this time, since the upper surface of the base 10 extends upstream from the guide rail 11, the table 2 can be easily placed on the upper surface of the base 10 and the table 2 can be positioned between the guide rails 11. Although the adherend 80 may be placed on the table 2 in advance, the adherend 80 may be placed after the table 2 is placed on the base 10. In any case, when the extension table 4 is pushed by sliding the first table 21 on which the adherend 80 is placed at a predetermined position as indicated by the arrow in FIG. 90 is pressed, the adhesive sheet 90 is pasted from the separation piece 45 of the extension table 4 to the thin plate 42, and the adhesive sheet 90 is continuously pasted from the extension table 4 to the upper surface of the table 21. . Since the adherend 80 is placed at a position spaced rearward from the front end 2 a of the table 21, the adhesive sheet 90 is placed in the front section of the upper surface of the table 21 where the adherend 80 is not placed. It is affixed and will be affixed on the to-be-adhered body 80 continuously. Then, as shown in FIG. 9, when the extension table 4 comes to a predetermined distance downstream from the pressing roller 3, the adhesive sheet 90 is located at a position between the extension table 4 and the table 21 (position P indicated by a two-dot chain line in the figure). Is removed, the extension table 4 is removed from the base 10, the adhesive sheet 90 is peeled off from the extension table 4 and discarded.

  The first table 21 is continuously pushed forward by hand, but the second table 22 is placed on the base 10 and slides before the entire first table 21 passes the pressing roller 3. The first table 21 is pushed by the second table 22. When the second table 22 is continuously pushed by hand, the adhesive sheet 90 is continuously attached to the second table 22 following the first table 21 as shown in FIG. When the first table 21 passes completely below the pressing roller 3 and is located downstream thereof, the first table 21 and the second table are the same as the extension table 4 described above. The adhesive sheet 90 is cut at a position between 22 (position P indicated by a two-dot chain line in the figure), and the first table 21 is removed from the base 10.

  Thereafter, the adherend 80 with the adhesive sheet 90 is removed from the first table 21 removed from the base 10, and the adhesive sheet 90 is adhered to a predetermined section before and after the first table 21. Therefore, the part is peeled off and the adherend 80 with the adhesive sheet 90 is removed. And if the surrounding margin part is excised, many business cards as described above can be created.

  In addition, when the adhesive sheet 90 is attached to three or more (three or more) adherends 80, the first table 21 after the adherend 80 with the adhesive sheet 90 is removed. Is again set on the upstream side of the pressing roller 3, and the second table 22 located on the front side thereof is pressed with it. Similarly, the second table 22 can be set again on the upstream side of the pressing roller 3 and used. Thus, the adhesive sheet 90 can be continuously affixed to many to-be-adhered bodies 80 by using the two tables 2 (tables 21 and 22) cyclically and repeatedly.

  And when the sticking process of the predetermined number (for example, 10 pieces) of the adherends 80 is completed as one lot, the table 2 on which the last adherend 80 is placed as shown in FIG. When passing under the pressing roller 3, the extension table 4 placed at another place is set again on the upstream side of the pressing roller 3. The last table 2 is pushed by the extension table 4 and is slid to the downstream side of the pressing roller 3. When the adhesive sheet 90 is attached to the separation piece 45 of the extension table 4, the last table 2 and the extension table 4 are moved. The adhesive sheet 90 is cut at a position in between. Further, the separation piece 45 of the extension table 4 is separated from the extension table main body 40, and the extension table main body 40 is removed from the upper surface of the base 10 as it is and stored in another place. On the other hand, the tip of the pressure-sensitive adhesive sheet 90 is attached to the separated separation piece 45, but as shown in FIG. 12 (a), the lower portion of the pressure roller 3 is passed in the reverse direction. To the upstream side. And the adhesive sheet 90 pulled out is wound up by the sheet roll 91 by reversely rotating the sheet roll 91 like FIG.12 (b). At that time, the release paper 92 taken up on the take-up shaft 16 is reattached to the adhesive sheet 90. Finally, when the separation piece 45 comes to a position close to the intermediate shaft 15, the release paper 92 is cut between the intermediate shaft 15 and the take-up shaft 16 until a predetermined number of pasting steps as the next lot. Keep it in that state. However, the release paper 92 is removed from the winding shaft 16 and discarded. When a predetermined number of pasting steps are performed next, the adhesive sheet 90 can be easily removed from the sheet roll 91 by gripping the suspended separation piece 45 and passing the lower portion of the pressing roller 3 to the downstream side. It can be pulled out.

  Thus, in the sheet sticking apparatus of this embodiment and the sheet sticking method using the same, the table 2 is moved to the original upstream position every time the sticking work to one adherend 80 is completed. There is no need to return it, and the operator simply pushes the table 2 forward, so the pasting operation is simple. In particular, since the table 2 is pushed from the upstream side, there is an advantage that the table 2 can be slid while visually confirming the pasting state. Accordingly, if wrinkles or the like occur in the adhesive sheet 90 during the pasting, the pasting operation is stopped and the table 2 is run backward, and the adhesive sheet 90 is pasted again, or the adhesive sheet 90 is placed at that position. It can also be cut and restarted, and the adhesive sheet 90 and the adherend 80 are unlikely to be wasted. In addition, since there are no other constituent members between the upper and lower sides of the intermediate shaft 15 and the pressing roller 3, the operator can easily see from the upstream side. Note that a release paper 92 that is directed from the intermediate shaft 15 to the take-up shaft 16 is present below the drawing portion S (see FIG. 1) from the sheet roll 91. Therefore, even if dust or the like is generated and dropped from the sheet roll 91 when it is pulled out from the sheet roll 91, the dust or the like falls on the release paper 92, and the table 2 that is slidingly moved downward is used. The possibility that dust or the like falls and adheres to the adherend 80 can be reduced.

  Further, by continuously sliding the two tables 2, the long adhesive sheet 90 can be continuously pasted on the respective adherends 80 on the two tables 2, efficiently. Pasting work can be performed. Further, since it is possible to cyclically use the table 2 that has passed through the pressing roller 3 again on the upstream side, only a minimum of two tables 2 are required, and the storage space for the table 2 can be reduced. In addition, since the length from the pressing roller 3 to the rear end 10b is longer than the length from the front end 10a of the base 10, the next table 2 is placed on the table 2 and prepared. In addition to being excellent in workability when placing the wearing body 80, it is possible to prevent the overall length of the apparatus main body 1 from becoming too long and to make the apparatus compact.

  Further, since the inner surface 11 a of the guide rail 11 is used as a guide surface to guide the side surface of the table 2, the side surface of the table 2 and the inner surface 11 a of the guide rail 11 are not easily worn, and the guide rail 11 is placed on the upper surface of the base 10. Since it is only necessary to attach the, the structure is simple and the assembly of the device is easy. Furthermore, since the upper surface of the base 10 is directly used as the moving path of the table 2, it can be slid as it is simply by placing the table 2 on the upper surface of the base 10.

  Furthermore, since the adherend 80 is placed at a position spaced rearward from the front end 2 a of the table 2, the adherend sheet 90 is attached after the adhesive sheet 90 is attached to the front section of the upper surface of the table 2. The adhesive sheet 90 will be affixed to the body 80, and the front part of the adherend 80 will be firmly fixed to the table 2 by the adhesive sheet 90. Therefore, the adherend 80 is prevented from being displaced or tilted during attachment, and the adhesive sheet 90 can be reliably attached to the adherend 80. The adhesive sheet 90 needs to be peeled off from the table 2 thereafter, but since the adhesive sheet 90 having the same width as the adherend 80 is used, the adhesive sheet 90 is attached to the table 2 on both sides of the adherend 80. Even if it sticks, it is slight. Therefore, the adhesive sheet 90 can be easily peeled from the table 2. In particular, since the upper surface of the thin plate 26 is a rough surface, the peeling operation of the adhesive sheet 90 is easy. For example, as shown in FIG. 4, a slight remaining section is also formed between the rear end 2b of the table 2 and the adherend 80, so that the table 2 and the subsequent table 2 When the adhesive sheet 90 is cut between the two, there is no possibility that the adherend 80 of the downstream table 2 is damaged. And since the to-be-adhered body 80 of the table 2 of an upstream is also in the position spaced apart back from the front end 2a of the table 2, damage to the to-be-adhered body 80 can also be prevented simultaneously.

  In addition, when the sticking process is started, the adhesive table 90 is first pasted as a run-up section using the extension table 4, so that the sticky sheet 90 is suddenly stuck to the table 2 or the adherend 80 on the table 2. The adhesive sheet 90 can be adhered to the adherend 80 more neatly than when attached. Moreover, since the extension table 4 can be used to push the last table 2 at the end of the attaching process, it has a high utility value.

  Further, since the extension table 4 has a structure capable of separating the separation piece 45, the separation piece 45 is separated after the tip portion of the adhesive sheet 90 is attached to the separation piece 45 at the start stage of the attaching process. Only that can be said to return to the upstream side through the lower side of the pressing roller 3. That is, in the case where the separation table 45 is not provided on the extension table 4, it is necessary to reversely move the entire extension table 4 under the pressing roller 3 and return it to the upstream side. Since the distance between the pressing roller 3 and the upper surface of the base 10 is narrow, if the separation piece 45 can be separated, only the separation piece 45 can be passed under the pressing roller 3 in the opposite direction, and the entire extension table 4 can be moved. Work is easier than when passing in the opposite direction.

  Moreover, since only the separation piece 45 can be kept attached to the adhesive sheet 90 as shown in FIG. 9 until the next attaching process after the attaching process is completed, the exposed portion of the adhesive layer can be minimized. it can. Also, when starting the next affixing process, only the separation piece 45 can be gripped and the lower part of the pressing roller 3 can be easily passed to the downstream side, so that a quick preparatory work can be performed.

  Moreover, since the separation piece 45 has the same width as the extension table 4, the pressure-sensitive adhesive sheet 90 is stabilized without the separation piece 45 rattling from side to side when sliding. Moreover, since the separation piece 45 is provided with the vertical plate portion 47 that comes into contact with the front surface of the extension table main body 40, the separation piece 45 can be moved when the extension table 4 is slid toward the downstream side. It is also possible to prevent the air from floating upward from 40 or coming off. Furthermore, since the separation piece 45 is simply configured to be placed on the extension table main body 40, the work required for the attachment / detachment is extremely simple.

  Various changes can be made to the shape and configuration of the separation piece 45. For example, the vertical plate portion 47 may be provided in a part of the width direction instead of being provided over the entire width. You may make it provide the vertical board part 47 in multiple places at intervals in the width direction. Further, the vertical plate portion 47 is not configured to contact the front surface of the extension table main body 40. For example, a groove is formed in the front portion of the extension table main body 40, and the vertical plate portion 47 is inserted into the groove from above. Good. Further, a vertical plate portion 47 is provided on the lower surface of the horizontal plate portion 46, or a projection having another shape is provided on the lower surface instead of the vertical plate portion 47, and is inserted into the recess of the extension table body 40 from above. Also good. Similarly, the horizontal plate portion 46 can be variously modified and may be provided in a part of the width direction similarly to the vertical plate portion 47. However, since the adhesive sheet 90 needs to be attached, a certain width is required. Alternatively, it is desirable to provide at a plurality of positions at intervals.

  Furthermore, the design of the configuration of the table 2 can be changed as appropriate, and the thin plate 26 as described above may not be provided, and at least the left portion in the traveling direction may be lowered by one step as a single configuration. Moreover, although the one-step lower part was formed continuously along the traveling direction, it may be formed intermittently or only partly. Furthermore, a groove may be provided on the upper surface of the table 2 continuously, intermittently, or only partially along the traveling direction to mark the groove. However, it is preferable to provide a step that is one step lower as described above, because the position of the adherend 80 can be adjusted while confirming the step not only visually but also with a fingertip.

  The number of the tables 2 may be three or more, and as described above, the plurality of tables 2 are used only once per lot, instead of setting the table 2 again on the upstream side and repeatedly using it. Thus, you may make it stick the adhesive sheet 90 to the some to-be-adhered body 80 continuously. For example, when affixing to 10 adherends 80 as one lot, 10 tables 2 may be prepared and sequentially set and affixed to the apparatus main body 1.

  Further, a protrusion for positioning the adherend 80 may be provided on the upper surface of the table 2. Furthermore, the adherend 80 may be locked by providing a lock mechanism on the table 2. In addition, the adherend 80 may be sucked and held on the table 2.

  The table 2 may be slid more smoothly by providing a roller or a ball on the side surface of the table 2 or the inner surface 11a of the guide rail 11. Further, a protrusion or groove may be formed on the inner surface of the guide rail 11, and a groove or protrusion that can be engaged with the protrusion or groove may be formed on the side surface of the table 2. Furthermore, a groove is provided on the upper surface of the base 10 and a protrusion that engages with the groove is formed on the lower surface of the table 2, and the groove of the base 10 can be used as a guide rail. It may be reversed. As described above, various configurations of the guide rail can be employed.

  Moreover, although the table 2 was slid manually, you may provide a drive part. Similarly, the supply shaft 13 and the take-up shaft 16 may be rotated by a drive unit. However, manually sliding as described above eliminates the need for a power source and increases the degree of freedom in the location where the apparatus is installed.

Moreover, in order to be able to respond | correspond widely from a thin to-be-adhered body to a thick to-be-adhered body with one apparatus, you may enable it to move the press roller 3 up and down. For example, a screw hole that penetrates up and down is formed in a member that supports both ends of the pressure roller 3, a bolt is screwed so as to penetrate the top and bottom, and the bolt is rotated around its axis to thereby rotate the screw roller 3. The height may be adjusted up and down.

  Two or more pressing rollers 3 may be provided at intervals in the traveling direction. In this case, the pressing forces may be different from each other. Furthermore, although the pressing roller 3 is used as the pressing member, a pressing member having a structure that does not rotate may be used so as to slide downward.
