By the way, in the above-mentioned automatic pasting device, the leading edge of the work being conveyed is detected using a reflective optical sensor, and after how many seconds the double-sided tape is started to be pasted from the detection time, and after how many seconds the double-sided tape is cut. or However, in this method, there is a problem that the end position of the double-faced tape is deviated due to slippage between the work conveying means and the work, waviness of the work, and the like.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a double-faced tape sticking apparatus capable of reducing deviation of the sticking end position of the double-faced tape.

The present invention comprises a work conveying means for conveying a sheet-shaped work from a work supply position where the work is supplied to a conveyance end position where conveyance of the work is completed; a work supply means for supplying the work to the work supply position; supplying a band-shaped double-sided tape having adhesive surfaces on both sides and having a release paper attached to one side to the work being transported from the work supply position toward the transport end position by the work transport means; double-sided tape applying means for cutting the double-sided tape to a predetermined length while applying the adhesive surface of the supplied double-sided tape on the side not covered with the release paper to the work; and the leading edge of the conveyed work. first detecting means for detecting an edge; second detecting means for detecting the trailing edge of the conveyed work; and based on the detection results of the first and second detecting means, the double-sided tape is A timing to start pasting from a pasting start position spaced rearward from the edge of the double-sided tape and a timing to finish pasting the cut double-sided tape at a pasting end position spaced forward from the trailing edge are calculated, and the double-faced tape pasting means is operated. and control means for controlling.

In the present invention, when the second detection means detects the trailing edge of the conveyed work, the control means calculates the timing at which the cut double-faced tape is pasted at the pasting end position spaced forward from the trailing edge. Therefore, the time from the detection of the trailing edge to the end of pasting can be shortened. Therefore, the distance of the work conveyed during that time can be shortened, and the influence of slippage between the work conveying means and the work with respect to the end position of sticking of the double-faced tape and waviness of the work can be reduced.

In the present invention, the arrangement of the first detection means and the second detection means is arbitrary, and the first detection means may be arranged on the front side in the conveying direction of the work, and the second detection means may be arranged on the rear side. The arrangement may be reversed. Alternatively, the first detection means and the second detection means can be arranged side by side in a direction perpendicular to the direction in which the work is conveyed. Furthermore, the function of the second detection means can be given to the first detection means. For example, if the first detection means continues to send an ON signal to the control means after detecting a workpiece, and the signal is turned OFF when the first detection means stops detecting a workpiece, switching on and off will cause the leading edge and the trailing edge of the workpiece to Edge detection becomes possible.

An embodiment according to the present invention will be described below with reference to the drawings.
[1] Overall structure of a double-sided tape application device Fig. 1 shows a strip-shaped double-sided tape applied to a sheet-like work 1 with the adhesive side on one side in a state where the release paper is not peeled off, and the double-sided tape is cut at a predetermined length. 1 is an overall view of a double-faced tape applying device 10. FIG. This double-faced tape sticking device 10 sticks a double-faced tape 2 to a workpiece 1. The double-faced tape 2 is rolled and accumulated on a winding frame 12 rotatably attached to the side surface 11a of a box-shaped case 11. a pasting means 20, a work conveying means 40 disposed above the base 16 for conveying the work 1, a work supply means 50 for positioning the work 1 at a predetermined position and supplying the work 1 to the work conveying means 40; A control unit 11c is provided in the case 11 and controls the operation of the double-sided tape applying device 10. As shown in FIG.

In FIG. 1, the workpiece 1 supplied from the workpiece supplying means 50 to the workpiece conveying means 40 is conveyed from the near side to the far side. The rotation axis of the winding frame 12 rotates about the horizontal direction orthogonal to the conveying direction of the work 1, and the double-sided tape 2 is rotated in the direction A in FIG. The work is pulled out in the direction opposite to the work conveying direction and supplied to the double-faced tape sticking means 20 .

FIG. 2 shows the double-sided tape sticking means 20 . As shown in FIG. 3, the double-faced tape applying means 20 is attached to the side surface 11a of the case 11 from the back side of the device 10 toward the front side (from the right side to the left side in FIG. 3(a)) and parallel to each other. It has a taper guide 21, a taper roll 22, a delivery roll 23 and a nip roll 24 which are arranged. The taper guide 21 is fixed to the side surface 11a, and each roll 22, 23, 24 rotates about a direction parallel to the rotation axis of the winding frame 12. As shown in FIG.

The taper guide 21 has flanges 21b at both ends of a conical body 21a whose diameter decreases toward the case 11 side, and is fixed to the side surface 11a. The taper roll 22 has flanges 22b at both ends of a cylindrical body 22a with a uniform diameter, and is rotatably supported on the side surface 11a. The delivery roll 23 consists of only a cylindrical body with a uniform diameter, and is rotatably supported on the side surface 11a. The delivery roll 23 is rotated in the work supply direction (in the direction of arrow B in FIG. 3(b)) by a rotation driving means (not shown). The delivery roll 23 incorporates a one-way clutch that regulates the rotation so that it rotates only in the work supply direction.

The nip roll 24 is rotatably supported by the tip of the arm 25 . The arm 25 extends substantially vertically, and the base end of the upper end is rotatably supported by the side surface 11 a of the case 11 . The arm 25 is moved to a retracted position where the nip roll 24 is separated from the feed roll 23 and the nip roll 24 is moved close to or in contact with the feed roll 23 as shown in FIG. and a nip position that forms a nip for workpiece transfer.

The taper guide 21 and the rolls 22 to 24 are made of a material having relatively good peelability, such as Teflon (registered trademark). The nip roll 24 has a configuration in which a plurality of rings 24b made of resin such as silicon are wound around a core metal 24a forming a cylindrical body at intervals.

FIG. 3A shows a state in which the double-sided tape 2 wound around the winding frame 12 is pulled out and supplied to the double-sided tape applying means 20 . In FIG. 3A, the upper surface of the double-sided tape 2 pulled out from the double-sided tape applying means 20 is a glue surface (adhesive surface) 2a, and the lower surface is a release paper surface 2b. The double-faced tape 2 wound around the winding frame 12 first contacts the body 21a of the tapered guide 21 with the release paper surface 2b. At this time, the diameter of the body 21a is reduced toward the case 11 side, so the double-sided tape 2 is slid toward the flange 21b of the taper guide 21 on the case 11 side. As a result, the lateral supply position of the double-sided tape 2 is positioned in a constant state.

Next, the adhesive surface 2a of the double-sided tape 2 contacts the body 22a of the taper roll 22, and the release paper surface 2b contacts the delivery roll 23. As shown in FIG. The delivery roll 23 is constantly rotating when the device 10 is in operation. However, since the release paper surface 2b of the double-sided tape 2 contacts the delivery roll 23, the delivery roll 23 and the double-sided tape 2 slide against each other, and the double-sided tape 2 is not conveyed by the delivery roll 23. In order to transport the double-sided tape 2, as shown in FIG. 3B, the arm 25 is swung toward the delivery roll 23 to bring the nip roll 24 close to or in contact with the delivery roll 23. A double-faced tape 2 is sandwiched between 24. - 特許庁Thereby, the rotational force of the delivery roll 23 is transmitted to the double-sided tape 2, and the double-sided tape 2 is further transported.

As shown in FIGS. 2 and 3(a), a cutter 26 having an upper blade 26a and a lower blade 26b for cutting the double-sided tape 2 at a predetermined position is arranged below the delivery roll 23 and the nip roll 24. It is A guide 27 is provided between the cutter 26 and the nip roll 24 to support the tip of the cut double-faced tape 2 . The surface 28 of the guide 27 is inclined in the feeding direction of the double-faced tape 2, and is formed as an uneven surface in which sharp peaks and valleys extending in the inclination direction are alternately arranged. This guide 27 is attached to the side surface 11 a of the case 11 via a stay 29 .

Below the cutter 26, an application guide 30 having a U-shaped cross section is arranged to guide the double-faced tape 2 supplied by the delivery roll 23 and the nip roll 24 to the work 1. As shown in FIG. The sticking guide 30 is formed to have a concave cross-section through which the double-sided tape can pass, and the bottom surface on which the double-sided tape 2 slides is inclined in the supply direction.

As shown in FIG. 2, in front of the sticking guide 30, a sticking roll 32 is arranged to press the supplied double-faced tape 2 against the work from the release paper surface 2b side. The pasting roll 32 is sandwiched between a pair of left and right side plates 31a of the frame 31, and is rotatably supported by the rear end of the frame 31 about a direction parallel to the rolls 22 to 24. ing.

A rod 13 extending in a direction parallel to the shaft 32a of the pasting roll 32 passes through the side plate 31a of the frame 31, and the frame 31 is supported by the case 11 via the rod 13. As shown in FIG. A pin 33 parallel to the rotation axis of each roll 22 to 24 is attached to the front end of the frame 31. As shown in FIG. A tension spring 15 is bridged between the extending support bar 14 .

The sticking roll 32 has a shaft 32a which can be tilted. The angle of inclination of the shaft 32a is adjusted by a sticking roll adjusting screw 34 attached to the side plate 31a on the front side in FIG. In accordance with this, the sticking direction angle of the double-faced tape 2 with respect to the traveling direction of the work is adjusted. That is, when the lamination roll adjustment screw 34 is rotated clockwise and screwed in, one end of the shaft 32a of the lamination roll 32 is pushed down, and the inclination angle becomes downward to the right with respect to the feed direction of the double-faced tape 2, thereby laminating the double-faced tape 2. Direction angle is adjusted to the right. Conversely, when the lamination roll adjusting screw 34 is rotated counterclockwise in the direction of loosening, one end of the shaft 32a of the lamination roll 32 is pushed up by a spring or the like by means of a biasing means, and the inclination angle is lowered to the left with respect to the feed direction of the double-faced tape 2. , thereby adjusting the sticking direction angle of the double-sided tape 2 to the left.

As shown in FIGS. 1 and 5, the work conveying means 40 is a pair of lower rolls (left and right in FIG. 5) rotatably suspended between the side plate 17 of the base 16 and the side surface 11a of the case 11. 41, a pair of front and rear upper rolls 42 and intermediate rolls 42A that are rotatably bridged between a plate 18 supported by the case 11 via a rod 13 and a support bar 14 and the side surface 11a of the case 11; A plurality of lower belts 43 wound around the lower roll 41 and a plurality of (three in FIG. 1) upper belts 44 wound around the upper rolls 42 are provided. The upper roll 42 on the upstream side is separated upward from the lower roll 41 , and the intermediate roll 42 A presses the upper belt 44 against the lower belt 43 . A wedge-shaped gap is formed between the upper roll 42 and the intermediate roll 42A, and the workpiece 1 is inserted into the gap. Between the intermediate roll 42A and the upper roll 42 on the downstream side, the upper belt 44 and the lower belt 43 are in contact with each other to reliably convey the workpiece 1. - 特許庁

On the left side of the work 1 in the direction of travel, as shown in FIG. A small belt 46 wound thereon is provided, and a backup roll 47 pressed against the small belt roll 45 is provided. That is, the work conveying means 40 of this embodiment includes a belt rotating body 44A in which an upper belt 44 is wound around a pair of front and rear upper rolls 42, and a belt in which a lower belt 43 is wound around a pair of front and rear lower rolls 41. and a rotating body 43A.

In FIG. 1, the front side is the supply side to which the work 1 is supplied (front side, upstream side of work transport), and the back side is the discharge side to which the work 1 attached with double-sided tape is discharged (rear side, work transport side). downstream). A feed table 51 constituting the work supply means 50 is arranged on the supply side of the work transport means 40 . A gap is formed between the upper end surface 17 a of the side plate 17 of the base 16 and the lower end surface 18 a of the plate 18 . The work 1 is sandwiched between the upper and lower belts 44 and 43 and conveyed. Since the work 1 protrudes from the gap, the work 1 can be conveyed, that is, the double-faced tape 2 can be attached.

A rotation driving mechanism (not shown) is connected to the supply-side lower roll 41 to which the work is supplied, and the supply-side lower roll 41 is used as a drive roll. That is, the lower roll 41 on the supply side is rotated in the direction of conveying the work (clockwise direction in FIG. 5). This rotation drive mechanism includes a driven mechanism (not shown) that rotates the upper roll 42 on the supply side in conjunction with the rotation of the lower roll 41. By rotating the lower roll 41 by the rotation drive mechanism, The upper roll 42 is rotated in the direction of conveying the work 1 (counterclockwise rotation in the figure). That is, in this embodiment, the upper roll 42 on the supply side is also configured as a drive roll, and the upper and lower rolls 41 and 42 on the discharge side are driven rolls driven by the rotation of the belts 43 and 44 . When the rolls 41 and 42 on the supply side rotate, the rolls 41 and 42 on the discharge side and the small belt roller 45 are rotated in the work conveying direction via the belts 43, 44 and 46, respectively. The workpiece 1 is conveyed from the supply side to the discharge side by being sandwiched between the belt 43 rotated by the rolls 41 and 42 and the small belt rollers 45 and the belts 44 and 46 .

The work supply means 50 includes a feed base 50, a guide plate 52 disposed on an upper surface 51a of the feed base 51 and having a reference surface 52a parallel to the direction in which the work advances, and a rotation guide plate 52 extending from a rotation drive mechanism (not shown). A feed roll 53 having a work contact portion 55 around which an O-ring 56 is mounted is formed at the tip of a shaft 54 , and a rotating shaft 54 is disposed on an upper surface 52 b of a guide plate 52 and supports the feed roll 53 . and a roll pressing plate 57 having a hook 58 engaged with the tip of the roll pressing plate 57 .

By rotating, the feed roll 53 feeds the work 1, which is supplied to the upper surface 51a of the feed table 51 and is in contact with the O-ring 56 of the work contact portion 55, to the work conveying means 40 in front. An intermediate portion of the rotating shaft 54 of the feed roll 53 is composed of a coil-shaped spring 54a, and the spring 54a is elastically deformed so as to bend forward and backward. The feed roll 53 is rotatable even when the spring 54a is bent. The rotary shaft 54 including the spring 54a is based on a state parallel to the axial direction of the rolls 41 and 42, but by moving the roll pressing plate 57 back and forth, the spring 54a is curved in the front and back direction, and the feed roll is rotated. The feeding angle of the work 1 by 53 is adjusted. The feed angle of the workpiece 1 associated with the degree of bending of the spring 54a is defined by fixing the roll pressing plate 57 to the guide plate 52 with screws 57a.

Normally, the spring 54a is slightly bent forward as shown in FIG. When the sheet-like work 1 is put on the upper surface 51a of the feed table 51 in an arbitrary state, the work 1 is conveyed forward by the feed rolls 53 and directed obliquely toward the guide plate 52 by the feed rolls 53. By receiving the stress, it is rotated in the direction of the guide plate 52, that is, to the left. As a result, as shown in FIG. 4, the left corner of the rear end comes into contact with the reference surface 52a of the guide plate 52. At this time, the workpiece 1 is tilted such that the left edge 1a forms an angle θ with the guide plate 52a. state. continue. The left edge 1a of the workpiece 1 conveyed forward by the feed roll 53 is tightly pressed against the reference surface 52a by the feed roll 53 . In this manner, the work 1 is straightened with respect to the conveying direction and then supplied to the work conveying means 40 .

On the upper surface 11b of the case 11, the position where the double-sided tape 2 starts to be applied (distance from the leading edge of the workpiece to the position where the application starts) and the position where the double-sided tape 2 ends (distance from the inner edge of the workpiece to the end of the application). An operation panel 60 for inputting is provided. Data adjusted by the operation panel 60 is supplied to control means (not shown), and the operations of the double-faced tape applying means 20 and the work transport means 40 are controlled.

[2] Configuration of Work Edge Sensor As shown in FIG. The first edge sensor A is a reflective photoelectric sensor that includes a light emitting portion and a light receiving portion. Light emitted from the light emitting portion is reflected by the work 1 and received by the light receiving portion, thereby detecting the work 1. . Specifically, the tip edge of the workpiece 1 is detected by changing the light receiving portion from an OFF state in which it does not receive light to an ON state in which it receives light.

A second edge sensor B is arranged behind the first edge sensor A and in an intermediate portion between the roll 41 and the backup roll 47 . The second edge sensor B is a photoelectric sensor equivalent to the first edge sensor A, and detects the trailing edge of the workpiece 1 when the light receiving portion changes from an OFF state in which it receives light to an ON state in which it does not receive light. As the first and second edge sensors A and B, transmissive photoelectric sensors can also be used.

[3] Operation of Double-sided Tape Applicator Next, the usage and operation of the double-sided tape applicator 10 will be described.
First, the operator inputs a sticking start position, a sticking end position, a conveying speed, and other necessary items on the operation panel 60 . Then, when the start button is pressed, the double-faced tape application device 10 operates as follows.

First, the tip of the double-faced tape 2 wound around the winding frame 12 is pulled out, the release paper surface 2b is brought into contact with the upper surface of the body 21a of the taper guide 21, and then the adhesive surface 2a is brought into contact with the lower surface of the tapered roll 22. Further, the leading end is pulled out to a position where it can be sandwiched between the delivery roll 23 and the nip roll 24.例文帳に追加

Next, the workpiece 1 is placed on the upper surface 51 a of the feed table 51 and brought into contact with the rotating feed roll 53 . Then, while the work 1 is fed forward by the feed roll 53, the end edge 1a is pressed against the reference surface 52a of the guide plate 52 to be straightened and supplied to the work conveying means 40 in this state. The work 1 supplied to the work conveying means 40 is sandwiched between upper and lower belts 43, 44 and 46 and conveyed from the supply side to the discharge side.

Next, the arm 25 swings toward the delivery roll 23 to sandwich the double-faced tape 2 between the delivery roll 23 and the nip roll 24 . Since the delivery roll 23 is constantly rotating, the double-faced tape 2 sandwiched between the delivery roll 23 and the nip roll 24 is immediately supplied toward the work 1. - 特許庁

When the workpiece 1 is conveyed by the belts 43 and 44 and the leading edge 1a of the workpiece 1 reaches the first edge sensor A, the first edge sensor A is turned on and its signal is input to the controller 11c. The distance from the detection position of the first edge sensor A to the nip point P of the roll 32, the conveying speed of the work, and the distance (for example, 1 cm) from the leading edge 1a of the work 1 to the pasting start position are input to the controller 11c. From these data, the time T1 from the time when the ON signal is received from the first edge sensor A to the time when the sticking start position of the double-faced tape 2 reaches the nip point P of the roll 32 is calculated. Then, the control unit 11c controls the double-sided tape applying means 20 so that the leading end of the double-sided tape 2 reaches the nip point P after the time T1 has passed, and the leading end of the double-sided tape 2 is placed between the sticking roll 32 and the work 1. The double-faced tape 2 starts to be applied from the application start position of the workpiece 1 in parallel with the edge 1c. The double-faced tape 2 is stuck in parallel with the edge 1c, for example, several millimeters inward from the edge 1c without peeling off the release paper.

Next, when the trailing edge 1b of the workpiece 1 reaches the second edge sensor B, the second edge sensor B is turned on, and its signal is input to the controller 11c. The control unit 11c is input with the distance from the detection position of the first edge sensor B to the nip point P of the roll 32 and the distance from the trailing edge 1b of the workpiece 1 to the pasting end position (for example, 1 cm). Based on these data, the time T2 from the time when the ON signal is received from the second edge sensor B until the end position of the double-faced tape 2 reaching the nip point P of the roll 32 is calculated. The controller 11c then controls the double-sided tape sticking means 20 so that the rear end of the double-sided tape 2 cut by the cutter 26 reaches the nip point P after the time T2 has elapsed. The tip of the double-sided tape 2 on the remaining side is supported by the surface of the guide 27 . As a result, the double-faced tape 2 is smoothly supplied to the supply side when the next workpiece 1 is pasted with the double-faced tape. The work 1 to which the double-sided tape 2 is attached is conveyed to the discharge side and discharged from the work conveying means 40 . As a result, the workpiece 1 having the double-sided tape 2 attached at a predetermined position is obtained.

The operation of the double-faced tape applying device 10 of this embodiment will be described in comparison with the prior art. Conventionally, the starting position of the double-sided tape 2 and the length of the double-sided tape 2 are input. As shown in FIG. 7, when the first edge sensor A detects the leading edge 1a of the work 1 (A), the double-sided tape 2 starts to be applied from a predetermined position on the work 1 at the nip point P (B). Then, when the workpiece 1 is conveyed by the input length of the double-sided tape 2, the double-sided tape 2 is pasted at the nip point P (C). In this method, after the first edge sensor A detects the leading edge 1a of the work 1, the work 1 is conveyed by the distance L1 until the double-faced tape 2 is completely applied.

On the other hand, in the double-faced tape applying device 10 of the above embodiment, as shown in FIG. , the second edge sensor B detects the trailing edge 1b of the workpiece 1 (B). After the time T2 calculated by the control section 11c, the double-sided tape 2 is applied to the workpiece 1 (C). According to the present embodiment, the work 1 can be conveyed by the distance L2 until the second edge sensor B detects the trailing edge 1b of the work 1 and the double-faced tape 2 is adhered to the work 1 .

As described above, in the double-faced tape applying device 10 of the present embodiment, the time from when the second edge sensor B detects the trailing edge 1b to when the pasting end position of the double-sided tape 2 reaches the nip point P of the roll 32 is Since T2 can be shortened, the distance of the work 1 conveyed during that time can be shortened, and the influence of slippage between the work conveying means 40 and the work 1 with respect to the sticking end position of the double-faced tape 2 can be reduced. It is possible to reduce the deviation of the sticking end position of the double-sided tape.

In the present invention, the object to which the double-sided tape is attached is not limited to paper such as an envelope, and may be a plate made of plastic or metal. If the object is made of metal, a magnetic sensor can be used as the detection means. Also, the second edge sensor B can be omitted and the first edge sensor A can have the function of the second edge sensor B. FIG. However, in this case, it is necessary to convey the entire length of the workpiece 1 from the detection of the leading edge 1a to the detection of the trailing edge 1b. .
