The sheet application device EA of the present invention comprises application means 10, which applies an adhesive sheet AS to an adherend WK so that the sheet sticks out from the adherend WK to form an application piece UP, and application piece transport means 20, which transports the application piece UP, and is disposed between supply means 30, which supplies the adherend WK, and storage means 40, which forms a storage area in which the application piece UP is stored until it is transported to the next process.

The attachment means 10 comprises a support roller 11 which supports an original roll RS having an adhesive sheet AS having an adhesive surface AS1 temporarily attached to one side of a release sheet RL, a guide roller 12 which guides the original roll RS, a peeling plate 13 as a peeling means which folds back the release sheet RL at the peeling edge 13A and peels the adhesive sheet AS from the release sheet RL, a pressure roller 14 as a pressing means which presses the adhesive sheet AS against the adherend WK to attach it, a drive roller 15 which is supported by an output shaft (not shown) of a rotary motor 15A as a drive device and which pinches the release sheet RL between itself and a pinch roller 15B, and a recovery roller 16 which is supported by an output shaft (not shown) of a drive device and which constantly applies a predetermined tension to the release sheet RL present between itself and the pinch roller 15B while the sheet attachment device EA is in automatic operation and which recovers the release sheet RL. In this embodiment, the attachment means 10 is configured to attach one adhesive sheet AS to multiple (three) adherends WK to form an attachment object UP.

The adhesive article transport means 20 includes a conveyor 21 that transports the adhesive article UP in a predetermined transport direction TD, an imaging means such as a camera or a photographing device that detects the position of the adhesive article UP, and a detection means 22 such as various sensors such as an optical sensor or an ultrasonic sensor, and a connecting means 23 that folds back the adhesive sheet AS attached to the adherend WK and connects the folded back sheet portion ASF to the unfolded sheet portion ASR that is not folded back.
The conveyor 21 includes a drive pulley 21B supported on an output shaft (not shown) of a rotary motor 21A serving as a driving device, a freely rotatable driven pulley 21C, and a belt 21D looped around the drive pulley 21B and the driven pulley 21C.
The connecting means 23 is supported by an output shaft 23B of a linear motor 23A as a driving device, and comprises a push-up member 23C that guides the tip of the adhesive body UP in the transport direction upwards, a drive pulley 23E supported by an output shaft (not shown) of a rotary motor 23D as a driving device, a freely rotatable driven pulley 23F, a belt 23G looped around the drive pulley 23E and the driven pulley 23F, and a guide member 23J with an arc portion 23H that guides the tip of the adhesive body UP in the transport direction downwards.

The supply means 30 includes a drive pulley 32 supported on an output shaft (not shown) of a rotary motor 31 as a driving device, a freely rotatable driven pulley 33, and a belt 34 looped around the drive pulley 32 and the driven pulley 33.

The stock means 40 includes a free roller conveyor 41 as a stock member equipped with a stop plate 41A against which the attachment object UP is stopped.

The operation of the sheet sticking apparatus EA will now be described.
First, a user of the sheet application device EA (hereinafter simply referred to as "user") sets the original roll RS on the sheet application device EA, in which each member is arranged in the initial position shown by the solid line in Fig. 1(A), as shown in the figure, and then inputs a signal to start automatic operation via an operation means such as an operation panel or a personal computer (not shown). Then, the application means 10 drives the rotary motor 15A to pay out the original roll RS, and when the leading end of the leading adhesive sheet AS in the payout direction is peeled off by a predetermined length by the peeling edge 13A of the peeling plate 13, the driving of the rotary motor 15A is stopped. Next, the supply means 30 drives the rotary motor 31, rotates the belt 34 in a counterclockwise direction to transport the adherend WK in the transport direction TD, and when the leading adherend WK reaches a predetermined position, the attachment means 10 drives the rotary motor 15A to unwind the original roll RS in accordance with the moving speed of the adherend WK, and the attachment transport means 20 drives the rotary motor 21A to rotate the belt 21D in a counterclockwise direction. As a result, the adhesive sheet AS is peeled off from the release sheet RL at the peeling edge 13A of the peeling plate 13, and as shown by the two-dot chain line in Fig. 1 (A), the adhesive sheet AS is pressed against the adherend WK by the pressing roller 14 and attached to the adherend UP, forming the attachment body UP. After that, the attachment body UP is transported in the transport direction TD by the conveyor 21, and when the next adhesive sheet AS is peeled off by a predetermined length at the peeling edge 13A of the peeling plate 13, the attachment means 10 stops driving the rotary motor 15A.

Next, when the detection means 22 detects that the adhesive body UP has reached a predetermined position, the adhesive body transport means 20 drives the rotary motor 23D and the linear motor 23A to rotate the belt 23G in a counterclockwise direction and raise the push-up member 23C, leading the leading end of the adhesive body UP in the transport direction upward to form the folded sheet portion ASF, as shown in Fig. 1(B). When the rotation of the belts 21D and 23G in the counterclockwise direction continues thereafter, the folded sheet portion ASF is guided downward along the arc portion 23H of the guide member 23J, as shown by the two-dot chain line in Fig. 1(B), and the folded sheet portion ASF is attached to and connected to the adhesive surface AS1 of the unfolded sheet portion ASR, as shown in Fig. 1(C). When the folded sheet portion ASF is attached to the unfolded sheet portion ASR, the attachment transport means 20 drives the linear motor 23A to return the push-up member 23C to its initial position, then drives the rotary motor 23D to rotate the belt 23G in a clockwise direction, and as shown in FIG. 1(D), the attachment portion UP, in which the folded sheet portion ASF and the unfolded sheet portion ASR are connected, is delivered to the free roller conveyor 41, and the same operations as above are repeated thereafter.

According to the above embodiment, the folded sheet portion ASF is connected to the unfolded sheet portion ASR, so that it is possible to minimize the possibility that the stock area for storing the patch UP will become full in a short period of time.

As described above, the best configurations, methods, etc. for implementing the present invention have been disclosed in the above description, but the present invention is not limited thereto. In other words, the present invention has been mainly illustrated and described with reference to specific embodiments, but those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Furthermore, the descriptions limiting the shapes, materials, etc. disclosed above are provided as examples to facilitate understanding of the present invention, and do not limit the present invention. Therefore, descriptions of the names of components that remove some or all of the limitations on the shapes, materials, etc. are included in the present invention.

For example, the attachment means 10 may employ a gas blowing means such as a blowing tube or nozzle that blows gas from between the supply means 30 and the peeling plate 13 in the direction of the pressure roller 14, and the gas may be blown from the gas blowing means to prevent the adherend WK from falling between the supply means 30 and the conveyor 21. Alternatively, the attachment body UP may be formed by attaching one or more adhesive sheets AS to one adherend WK, or the attachment body UP may be formed by attaching one or more adhesive sheets AS to multiple adherends WK. Alternatively, a closed loop cut or a cut in the entire short width direction may be formed in a strip-shaped adhesive sheet base material temporarily attached to the peeling sheet RL, and a predetermined area partitioned off by the cuts may be repeatedly cut to form the original roll of adhesive sheet AS. Alternatively, a raw roll in which a strip-shaped adhesive sheet base material is temporarily attached to a release sheet RL may be used, and a closed loop-shaped cut or a cut in the entire short width direction may be formed in the adhesive sheet base material by a cutting means, and a predetermined area partitioned by the cut may be used as the adhesive sheet AS. Alternatively, instead of rollers such as the support roller 11 and the guide roller 12, the raw roll RS and release sheet RL may be supported or guided by a plate-shaped member or a shaft member, or the raw roll RS may be supported by folding, for example, fanfold, without being rolled up. Alternatively, the release sheet RL may be folded, for example, fanfold, without being rolled up, or may be shredded with a shredder or collected randomly, or the release sheet RL may not be collected at all.
