JP 2002-2647 A JP 2006-193169 A

However, in the sheet sticking device of Patent Document 1, when a plurality of adhesive sheets are stuck to one adherend, the holding means reciprocates between the sheet supply means and the adherend many times. There is an inconvenience that the adhesive sheet attaching ability per unit time cannot be improved.
In that respect, the sheet sticking device of Patent Document 2 does not require the holding means to repeat the reciprocating operation many times as in Patent Document 1, but changes in the adhesive sheet sticking interval on the adherend or one sticking. There is an inconvenience that a quick response cannot be made when the number of adhesive sheets applied in operation is changed. Specifically, in Patent Document 2, although the configuration is such that the application interval can be changed, the adjustment of the interval requires disassembling the device and adjusting the screwing amount of the screw member. In addition, when the number of adhesive sheets to be applied is changed, it is necessary to replace the original adhesive sheet and to replace the holding means with a different one.

[Object of invention]
The object of the present invention is to change the interval between the adhesive sheets on the adherend or to change the number of adhesive sheets applied in one application operation when holding and attaching a plurality of adhesive sheets with the holding means. It is an object of the present invention to provide a sheet sticking apparatus and a sticking method that can quickly cope with cases, and can stick adhesive sheets to an adherend efficiently and sequentially.

In order to achieve the above object, the present invention provides a supply means for supplying an adhesive sheet provided with an adhesive layer on one surface of a base sheet, and an adhesive sheet supplied from the supply means on the other side of the base sheet. A holding means capable of holding a plurality of surfaces from the surface side, and a pressing means capable of pressing and adhering the adhesive sheet held by the holding means to the adherend,
The pressing means is provided so that a plurality of adhesive sheets held by the holding means can be sequentially attached,
The holding means is movable in the same direction as the adhesive sheet when supplied from the supply means, and in a support direction that intersects the supply direction of the adhesive sheet and in a sticking direction opposite to the support direction. A plurality of adhesive sheets are sequentially held when moving in the supporting direction, and a plurality of adhesive sheets can be sequentially applied to predetermined positions of the adherend when moving in the attaching direction. Is adopted.

Furthermore, the attaching method of the present invention includes a step of supplying an adhesive sheet provided with an adhesive layer on one surface of the base sheet,
Holding the plurality of adhesive sheets from the other surface side of the base sheet when the holding means moves in a support direction that is in the same plane as the supplied adhesive sheet and intersects the supply direction of the adhesive sheet A step of sequentially holding by means ,
And a step of sequentially pressing and sticking a plurality of adhesive sheets to a predetermined position of the adherend when the holding means moves in the sticking direction opposite to the support direction .

  According to the present invention, a plurality of adhesive sheets held at a time by the holding means can be efficiently and sequentially attached to the adherend, and the interval between the adhesive sheets to be attached can be easily adjusted. . As a result, it is impossible to quickly respond when the adhesive sheet application interval on the adherend is changed as in the past or when the number of adhesive sheets applied in one application operation is changed. Can be eliminated.

  In addition, the holding means is moved in the supporting direction to hold the plurality of adhesive sheets in order, while the holding means is moved in the application direction opposite to this to apply the plurality of adhesive sheets in order, so that the adhesive sheet is held. And the movement of the holding means repeated by sticking can be reduced as much as possible, and the number of sticking sheets of the adhesive sheet per unit time can be increased.

Furthermore, since the detection means detects the adherend and determines the number of adhesive sheets to be attached to the adherend, the adhesive sheet may be continuously attached to various adherends, Even when the number of adhesive sheets applied varies from body to body, this can be quickly and easily handled.
Here, the one sticking operation is an operation from when the holding means receives the adhesive sheet or sheets from the supplying means to when the holding means attaches the adhesive sheet to the adherend or adhesive bodies. That means.

Has been. The driving roller 24 is rotatably provided via a motor M as a driving device. The print head 21 can be printed on an adhesive sheet S made of thermal paper or printed using an ink ribbon, and is composed of a thermal head capable of printing variable information. The head 21 may be configured by a stamp that performs only predetermined printing, or a printer that performs printing.

  The suction head 12 has a suction area composed of a large number of holes 30, and the suction area located at the lowest level in FIG. 1 is defined as a first suction area 31, and the suction areas positioned at the second to fourth levels are defined as second to second levels. Let it be the fourth adsorption regions 32 to 34. Each adsorption region 31 to 34 is provided in a size corresponding to the adhesive sheet S. The holes 30 in each of the adsorption regions 31 to 34 are connected to a suction pump via a solenoid valve (not shown). Thus, the suction head 12 is provided so that a maximum of four adhesive sheets S can be sucked and held from the other surface of the base sheet, that is, the upper surface side in FIG. 2, and independently in each suction region 31 to 34. The adhesive sheet S can be adsorbed and released. Further, the holes 30 of the respective adsorption regions 31 to 34 are also connected to a pressurizing pump via an electromagnetic valve or the like (not shown). Thereby, each adhesive sheet S held by the suction head 12 can be sprayed independently toward the adherend W, and the adhesive sheet S can be pressed against the adherend W and pasted. The holding unit is configured by the suction head 12, the electromagnetic valve, and the pressure reducing pump, and the pressing unit is configured by the suction head 12, the electromagnetic valve, and the pressure pump.

  The moving means 16 includes a linear motion motor 41 as a driving device, and the slider 41A supports the suction head 12. The linear motor 41 is in the same plane as the adhesive sheet S supplied from the supply means 11 and intersects the supply direction (right direction in FIG. 1) of the adhesive sheet S (vertical direction in the figure). The suction head 12 is provided so as to move back and forth. Here, the downward direction in FIG. 1 is defined as a support direction D1, and the upward direction in FIG.

  The detecting means 17 includes a light emitting / receiving type line sensor 43 that receives light emitted from the light projector, and controls the position data where the light is blocked by the adherend W conveyed by the conveying means CV. The number of stacked cases C constituting the adherend W can be specified, and the number of adhesive sheets S to be attached to each case C can be determined. When individual information is provided for each case C, the detection means 17 can be provided with individual information reading means.

Next, the overall operation of this embodiment will be described.
In the case of the present embodiment, the adherend W is transported on the transport means CV with the case C having a maximum of four stacks and the number of stacks being random. And the sheet sticking apparatus 10 sticks the adhesive sheet S to each case C one by one. In addition, information on the height of one case C (the height in the vertical direction in FIG. 1) is input in advance to the control means PC.

First, when the adherend W whose number of stacked cases C is unknown is transported by the transport means CV, the line sensor 43 detects the height of the adherend W, and the control means PC detects the detection result. From the height information of one case C input in advance, the number of stacked cases C on the adherend W is specified, and the number of adhesive sheets S to be attached to the adherend W is determined.
Here, as shown in FIG. 3, the case where the adherend W is specified as being stacked in three stages will be described. The control means PC includes a feeding command for feeding the three adhesive sheets S to the supply means 11. Then, a print command for applying a predetermined print to the print head 21 is output. Here, the first adhesive sheet S1 is the adhesive sheet S that the supply unit 11 first feeds after the feeding command is input, and the second and third adhesive sheets S2 are the second and third adhesive sheets S that are fed. S3. Further, as shown in FIG. 3A, the case C positioned at the uppermost stage is defined as a first case C1, and the second and third cases C2, C3 are defined from the first case C1 toward the lower stage. When individual information such as a bar code (not shown) is provided in each of the first to third cases C1 to C3, individual information reading means such as a bar code reader (not shown) at the same time as the height detection by the line sensor 43. Thus, the individual information can be read and the individual information can be printed on each of the first to third adhesive sheets S1 to S3 by the print head 21.
Then, the first to third adhesive sheets S1 to S3 are sequentially peeled off by the peel plate 22 and supplied to the suction head 12 side (right direction in FIG. 1) waiting on the front end side of the peel plate 22, and these adhesive sheets S In accordance with the supply timing, the suction head 12 is intermittently moved in the support direction D1 by the operation of the linear motor 41, and the three adhesive sheets S are sequentially sucked and held by the suction head 12. Specifically, as shown in FIG. 3B, after the first adhesive sheet S1 is sucked and held in the first suction region 31 by the operation of a decompression pump (not shown), the suction head 12 is As shown in FIGS. 3C and 3D, the second and third adhesive sheets S2 and S3 are sucked and held in the second and third suction regions 32 and 33, respectively. Is done. Then, as shown in FIG. 3E, the third suction region 33 stops in a state where the height of the sticking position in the third case C3 is reached. In the case of this embodiment, the center position of each case C in the vertical direction in FIG. 1 is pasted with the center position of each adhesive sheet S in the vertical direction in FIG.
Next, when the adherend W reaches a predetermined position with respect to the suction head 12, it is detected by a sensor (not shown), and the conveyance is stopped by a stopper (not shown). When the adherend W is stopped, as shown in FIG. 3 (F), the suction in the third suction region 33 is released, and at the same time, the pressure pump (not shown) is operated to attach the third adhesive sheet S3 to the second 3 It sprays toward case C3 and affixes it in a predetermined position.

Next, the suction head 12 is moved in the sticking direction D2 by the operation of the linear motor 41 (the amount of movement is the same as the height of one adherend W), and as shown in FIG. The second adsorbing area 32 stops in a state where it is at the height of the sticking position in the second case C2, and the second adhesive sheet S2 is stuck at a predetermined position in the second case C2 by the same operation as the third adhesive sheet S3. . Further, as shown in FIG. 3 (H), the third adhesive sheet S3 is affixed to a predetermined position of the third case C3 by the same operation as the second adhesive sheet S2. Thereafter, the adherend W is released from being stopped by a stopper (not shown) and is conveyed downstream by the conveying means CV. Thereafter, the suction head 12 is returned to the position shown in FIG. 3A, and thereafter the same operation is performed.
In addition, when the number of cases C stacked on the adherend W is two-tiered or four-tiered, there is a difference between whether the adhesive sheet S is pasted in two stages or four stages, but the above three stages Since the adhesive sheet S is affixed in the same manner as shown in the stacking example, the description is omitted.
Here, when the adherend W consisting of a single case C that has not been stacked has been transported, the suction head 12 sucks and holds one adhesive sheet S in the first suction region 31, The suction head 12 is moved in the support direction D <b> 1 by the operation of the linear motion motor 41, and the first suction area 31 stops in a state where the sticking position in the case C is at the height. Next, after sticking the adhesive sheet S to the case C, the suction head 12 may be returned to the initial position by moving the suction head 12 in the sticking direction D2 by the operation of the linear motor 41.
In addition, when the height of the case C is changed, the height information of one case C that is input in advance to the control means PC may be changed.

  Therefore, according to such an embodiment, when the plurality of adhesive sheets S are held and pasted by the suction head 12, a change in the pasting interval of the adhesive sheets S on the adherend W or a single adherend W can be changed. Even when the number of the adhesive sheets S to be applied is changed, it is possible to respond quickly, and the adhesive sheets S can be applied to the adherend W efficiently and sequentially. In addition, since the suction head 12 is moved in the support direction D1 to sequentially hold the adhesive sheets S, the suction head 12 is moved in the sticking direction D2 and the adhesive sheets S are sequentially attached. As compared with the case where the operation of holding one sheet at a time and repeating the operation of applying one sheet at a time is repeated, the ability to apply the adhesive sheet S per unit time can be improved.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
In other words, the present invention has been illustrated and described mainly with respect to specific embodiments, but without departing from the scope of the technical idea and object of the present invention, the shape, position, or With respect to the arrangement and the like, those skilled in the art can make various changes as necessary.
Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

For example, in addition to using the line sensor 43, the detection unit 17 uses an imaging unit such as a camera, a photoelectric tube, a limit switch, or the like, or a weight incorporated in the conveyance unit CV as indicated by a dotted line in FIGS. 1 and 2. A sensor 45 may be used. In this case, the weight sensor 45 is provided so as to be able to detect the weight of the adherend W before the adhesive sheet S is pasted, and the weight information of one case C is previously input to the control means PC. The step number of the adherend W is specified from the detection result and the weight information of one case C input in advance by the control means PC, and the number of the adhesive sheets S to be attached to the adherend W is determined. It is determined.
The line sensor 43 and the weight sensor 45 may coexist. In this case, the possibility of erroneously recognizing the number of adhered adhesive sheets S is reduced.
Further, if the detection means 17 is constituted by an imaging means such as a camera, the control means PC can determine the number of stacked cases C, the attachment position of the adhesive sheet S, the attachment interval of the adhesive sheet S, and the like.

  Further, the supply means 11 can be variously modified as long as the adhesive sheet S can be supplied.

Furthermore, the pressing means may be changed as long as the adhesive sheet S can be pressed and adhered to the adherend W. For example, the entire suction head 12 or each suction area is made independent from each other in FIG. You may employ | adopt the air cylinder as a drive device moved to an up-down direction.
In addition, the driving device in the embodiment employs electric devices such as a rotation motor, a linear motion motor, a single axis robot, and an articulated robot, actuators such as an air cylinder, a hydraulic cylinder, a rodless cylinder, and a rotary cylinder. In addition, a combination of them directly or indirectly can be adopted (some of them overlap with those exemplified in the embodiment).
Furthermore, although the example in which the several to-be-adhered body W was stacked was shown, the some to-be-adhered body W may be arranged side by side.
In addition, the adherend W is also applicable to a case where a plurality of adhesive sheets S are attached to a single adherend W other than a plurality of cases C as in the embodiment. be able to.
Furthermore, in the above-described embodiment, the suction head 12 has four suction areas. However, the suction head 12 has four or more suction areas in consideration of the maximum number of adherends W transported by the transport means CV. It is good.
Moreover, in the said embodiment, although the support direction D1 and the sticking direction D2 were made into the orthogonal direction which is an up-down direction in FIG. 1 with respect to the supply direction of the adhesive sheet S, the said support direction D1 and the sticking direction D2 are supplied. It is good also as a direction which cross | intersects diagonally with respect to the supply direction of the adhesive sheet S in the same plane as the adhesive sheet S.
