There is a problem that the tape A1 cannot be stuck to the corner N5 near the standing wall N1.

In the apparatus disclosed in Japanese Utility Model Application Laid-Open No. 64-14769, as can be understood from FIG. 12, when the vertical wall portion N1 is formed in the vicinity of the surface N3 to which the workpiece N is to be attached, the band-shaped sealing is performed. Since the support base 204 provided with the gears 300 to 303 having a function of feeding the material C1 interferes with and collides with the upright wall portion N1, the ability to attach the band-shaped sealing material C1 to the corner near the upright wall portion N1 is as follows. Not enough.

Further, in the apparatus disclosed in Japanese Utility Model Laid-Open Publication No. 64-14769, the release paper of the band-shaped sealing material C1 is separated from the band-shaped sealing material C1 and then sucked into the pipe 400 and collected. It is also conceivable to take up this instead of a take-up roller. However, simply winding up may apply too much tension to the release paper, or may loosen it too much, adversely affecting the attachment of the band-shaped sealing material C1.

The present invention has been made in view of the above circumstances. The first object of the present invention is to avoid interference and collision between the base and the upright wall by adopting means for relatively separating the base and the pressing body along the direction in which the upright wall of the work is erected. An object of the present invention is to provide a pad sticking machine capable of sticking a band-shaped pad to the vicinity of a standing wall portion even if the standing wall portion exists.

[0011]

The function of claim 1 will be described together with the method of use. First, the base is moved relative to the workpiece along the surface to which the workpiece is to be attached. At this time, the feeding unit feeds the band-shaped pad to the position where the workpiece is to be adhered on the surface to be adhered. The pressing body lands on the surface of the workpiece to be stuck. Therefore, the pressing body presses the belt-shaped pad fed by the feeding section against the surface to which the workpiece is to be stuck. As a result, the adhesive surface of the band-shaped pad is pressed against and adhered to the surface to be adhered of the work.

When the vertical wall portion and the base portion of the work approach each other, the driving unit is driven. As a result, while the pressing body lands on the adhered surface of the work and presses the band-shaped pad against the adhered surface of the work, the pressed body and the base are relatively separated from each other along the standing direction of the vertical wall of the work. I do. By this separation, interference and collision between the base and the standing wall are avoided. After avoiding interference and collision,

Therefore, the slide arm 63 can slide a predetermined length with respect to the second arm 62 in the length direction of the long hole 63c, that is, along the direction of the arrow E shown in FIG. Here, when the pressing roller 46 is at the position T1 as shown in FIG. 5, the distance between the axis of the pressing roller 46 and the feed gear 21 is L1.

As can be understood from FIG. 5, the center of the switching link 6 is pivotally supported by the feed shaft 20 as described above. Therefore, the switching link 6 can swing in the directions of the arrows N1 and N2. On the end side of the first arm 61, a switching gear 65 is

0 is attached to the hand 80x. Further, a pad reel 84 in which band-shaped pads S are wound in multiple layers is held by a mounting bracket 80i of an elbow 80y. The belt-shaped pad S is supported by a hanging prevention bar 85. Control means 86
Controls the operation of the robot arm 80, the operation of the air cylinder 17, the operation of the drive motor 7, and the operation of the rodless cylinder 40. In the internal memory or the external memory of the control means 86, data such as a sticking start end, a sticking end, a sticking trajectory, a separation start position between the base 10 and the pressing roller 46 in the work N, etc. are stored in advance by teaching or the like. Therefore, each command signal such as a separation start signal is output from the control unit 86 to the robot 8.

(Usage and Effects of Embodiment) First, as shown in FIG. 1, a band-shaped pad S is inserted from a pad entrance 11 of a base 10. When the thickness of the band-shaped pad S changes, FIG.
Loosen the fixture 10r shown in FIG.
1. Move in X2 direction. In this example, the guide roller 15
The band-shaped pad S is guided to the feed roller 2 by the cooperative action of the guide plate 15 and r. The control means 86 outputs a command signal to the air cylinder 17 to contract the air cylinder 17 while the band-shaped pad S is inserted in this manner. As a result, the air cylinder 17 rises in FIG. 5 and the pressing roller 46 rises in the direction of the arrow Y1 to reach the position T1 shown in FIG. Then, the switching link 6 rotates about the feed shaft 20 in the direction of the arrow N2 together with the switching gear 65, and the switching gear 65 meshes with the drive gear 70. When the drive motor 7 rotates in response to the motor-on signal from the control means 86 in the meshed state, the drive gear 70 rotates and the feed gear 21 through the switching gear 65 and the intermediate gear 66.
Rotate, and the feed roller 2 rotates.

The belt-shaped pad S inserted from the pad inlet 11 is fed in the direction of arrow Y3 shown in FIG. 1 by the rotation of the feed roller 2, and is transferred to the lower side of the pressing roller 46 via the fixed guide 13. You. When the free tip of the band-shaped pad S reaches below the pressing roller 46, a photoelectric sensor (not shown) detects this, and a motor-off signal is output from the control means 86, and the driving motor 7 is turned off, and the feeding of the band-shaped pad S is started. It is stopped, and the free front end of the band-shaped pad S stops at a fixed position.

Since the feed gear 21 also rotates during the feeding of the band-shaped pad S, the pressing roller 46 also rotates in the same direction via the timing belt 42 and the pressing gear 41 as can be understood from FIG. I do. After the free leading end of the band-shaped pad S is transferred to the lower side of the pressing roller 46 in this manner, the release paper S1 is manually removed from the free leading end of the band-shaped pad S.
Then, the leading end of the release paper S1 is attached to the take-up reel 3 via the guide roller 14 (see FIG. 1). This work is performed on the base 10
The door 10p (see FIG. 3) provided with the hinge 10k is opened. After the operation, the door 10p is closed. The adhesive surface of the belt-shaped pad S is exposed by the release of the release paper S1, and faces the pad running surface 13a of the fixed guide 13 as can be understood from FIG.

When the release paper S1 is mounted on the take-up reel 3 as described above, the air cylinder 17 is extended by the command signal of the control means 86 to lower the pressing roller 46 in the direction of arrow Y2, and the position shown in FIG. Let it be T2. Thereby, the adhesive surface of the band-shaped pad S is pressed against the surface N3 to be adhered of the work N. Then, the adhesive surface at the free front end of the band-shaped pad S is adhered to the surface N3 to be adhered and adhered.

As described above, the pressure roller 46 is lowered to the position T2, and the adhesive surface of the belt-like pad S is
Paste on 3. When the pressing roller 46 is thus lowered, the switching link 6 swings in the direction of the arrow N1, the switching gear 65 is switched, and the switching gear 65 is separated from the driving gear 70. Therefore, the drive gear 70 and the switching gear 65 are in a non-meshing state.

Next, the control means 86 outputs a command signal for operating the robot arm 80. Therefore, the control means 86
The base 10 moves along the direction of the arrow X2 shown in FIG. 1 along the sticking locus stored in advance in the memory. Then, the pressing roller 46 that comes into contact with the band-shaped pad S adhered to the surface N3 to be adhered of the work N rotates due to friction with the pad material of the band-shaped pad S. Along with this, the feed roller 2 also rotates in the same direction via the timing belt 42 and the feed gear 21, thereby feeding the belt-shaped pad S in the direction of the arrow Y3 (see FIG. 1).

Here, in the present embodiment, substantially as described above (the distance that the base 10 has been moved in the direction of the arrow X2 by the robot arm 80 = the rotation distance of the pressing roller 46 = the rotation distance of the feed roller 2 = the belt-like shape) (The feed length of the pad S), so that the feed roller 2 accurately feeds the band pad S corresponding to the consumed length of the band pad S consumed by sticking.

When the feed roller 2 rotates as described above, the take-up reel 3 also rotates via the feed shaft 20, the feed gear 21, the intermediate gear 38, and the take-up gear 31, as can be understood from FIG. The release paper S1 separated from the pad S is also automatically wound on the take-up reel 3 without slack. In this example, the number of teeth of the gears 21, 38 and 31 is set so that the number of rotations of the take-up reel 3 is slightly larger than the number of rotations of the feed roller 2. Appropriate tension acts on the release paper S1 to be released, and the release paper S1 can be prevented from being loosened. At this time, if the tension acting on the release paper S1 becomes excessive, the torque transmission cutting function of the clutch mechanism 5 is exhibited. That is, as can be understood from FIG. 6, the indenter 54 of the regulating shaft 53 is
It becomes slippery relative to t. Transmission of torque between the square shaft 50 and the round shaft 52 is prevented. As a result, even if the take-up gear 31 rotates, the take-up reel 3 does not rotate, that is, the take-up gear 31 idles with the take-up reel 3 stopped, and the release paper S due to excessive tension.
1 is prevented from breaking. When the excessive tension is released, the torque can be transmitted again by the pressing action of the indenter 54 urged by the spring 53i.

In this embodiment, the robot arm 80 is
0 is moved in the direction of the arrow X2 by a predetermined distance along the sticking locus, and when the band-shaped pad S is stuck to a predetermined position, the rodless cylinder 40 of the cutting section 4 is actuated and the blade body 42 descends to move the band-shaped pad S Is disconnected. After cutting as described above, the control means 86 controls the robot arm 80 to transfer the base 10 to the next attaching position. Feeding of the band-shaped pad S is performed during the transfer. That is, the air cylinder 17 is operated by the control means 86 to raise the pressing roller 46 to the position T1 (see FIG. 5), and the switching link 6 is rotated in the direction of the arrow N2.
5 is switched to the meshing position, and the switching gear 65 and the driving gear 70 are meshed. In this state, the control means 8 is engaged.
6, the drive motor 7 is driven by the drive gear 70
, The driving gear 70, the switching gear 65, the intermediate gear 6
6. The feed gear 21 rotates, the feed roller 2 rotates, and the belt-shaped pad S is fed. When the free front end, which is the cut end of the belt-shaped pad S, reaches below the pressing roller 46, this is detected by the not-shown photoelectric sensor as described above, and the drive motor 7 is stopped by the motor-off signal from the control means 86. Then, the feeding of the band-shaped pad S is stopped.

Now, a description will be given of a case where the band-shaped pad S is stuck on the main surface, that is, as shown in FIG. In this case, the base 10 interferes with and collides with the standing wall portion N1, so that it is necessary to avoid this. However, as long as no interference or collision occurs, the band-shaped pad S is pressed by the pressing roller 46 as described above, and the adhesive surface S5 (see FIG. 7) is stuck to the surface N3 to be stuck. on the other hand,
As shown in FIG. 7, when the pressing roller 46 approaches the standing wall portion N1 and the base 10 is likely to interfere with and collide with the standing wall portion N1, the control means 86 issues a command signal to further lower the air cylinder 17 in the arrow Y2 direction. A command signal for raising the base 10 in the direction of the arrow Y1 is output to the robot 8 while being output to the air cylinder drive circuit.

As a result, as can be understood from FIG. 7, the air cylinder 17 further descends, and the pressing roller 46 descends in the direction of arrow Y2 to the position T3, and the bottom surface 10m of the base 10 lifted by the robot arm 80. Is disposed above the upper end N4 of the standing wall portion N1. That is, the base 10 moves away from the pressing roller 46 along the direction in which the standing wall portion N1 of the work N is erected, that is, in the direction of the arrow Y1. By this separation, interference and collision between the base portion 10 and the standing wall portion N1 are avoided.

At this time, as can be understood from FIG. 7, as the pressing roller 46 descends, the slide pin 64 relatively slides along the long hole 63c, and the slide link 63 moves to the second arm 6
2, the distance between the axis of the pressing roller 46 and the feed gear 21 (the feed roller 2) is L2. Here, L2 is longer than L1 by ΔL (L2 = L
1 + ΔL). At this time, the rubber timing belt 42 extends by ΔL and follows the slide of the slide link 63.

As described above, in the present embodiment, the standing wall portion N1 (height: for example, 40 mm) is provided near the surface N3 to which the workpiece N is to be attached.
7), the pressure roller 46 is left on the surface N3 to be bonded of the work N as shown in FIG. 7, in other words, the band-shaped pad S is bonded with the pressure roller 46. The base 10 is lifted by the robot arm 80 along the direction in which the upright wall N1 is erected, that is, in the directions of the arrows Y1 and Y2, and the base 10 is separated from the pressing roller 46. Interference and collision between the base 10 and the standing wall N1 can be avoided.

This will be described with reference to the schematic diagram shown in FIG. In FIG. 9, the height of the standing wall portion N1 is H, the diameter of the pressing roller 46 is D, and α is a desired value. Then, the base 10 is moved by the robot arm in the direction of arrow X2 to the wall N1.
Transfer to. At this time, ΔH + α
When the axis of the pressing roller 46 reaches the position M1 at a distance of + (１ ／) × D｝, or before the base 10 collides with the standing wall portion N1 before reaching the position M1. The base 10 is lifted so that the bottom surface 10m of the base 10 exceeds the upper end N4 of the standing wall portion N1. This is performed by the control means 86 controlling the robot arm 80.

At this time, the base 10 is lifted while the pressing roller 46 lands on the surface N3 to be stuck and presses the band-shaped pad S, so that the band-shaped pad S protrudes from the pad outlet 12. When the band-shaped pad S protrudes from the pad outlet 12 by a distance corresponding to the distance of {H + α}, the cutting section 4 is operated to cut the band-shaped pad S with the blade body 42 to obtain a cut end Sx. Next, the upper end N4 is operated by the operation of the robot arm 80.
The base 10 lifted further upward is further moved in the direction of the arrow X2 to move the pressing roller 46 closer to the standing wall portion N1.

That is, while the base 10 is being lifted, the standing wall N
The axis of the pressing roller 46 is made to approach the standing wall portion N1 from 1 to a position M3 separated by a distance of {(1/2) × D}. At this time, as can be understood from FIG.
3 and the pressing roller 46 that has landed.
Then, the band-shaped pad S is stuck on the surface N3 to be stuck of the work N.
Therefore, the cut end Sx of the band-shaped pad S is arranged at almost the position M3. Therefore, in this example, the band-shaped pad S can be attached to the vicinity of the upright wall portion N1.

As described above, in the present embodiment, even when the standing wall N1 is near the surface N3 to which the workpiece N is to be attached, interference and collision between the standing wall N1 and the base 10 can be avoided, and the standing wall N1 can be prevented.
, The band-shaped pad S can be attached to a position M3 where the axis of the pressing roller 46 approaches the standing wall portion N3 to about half of the diameter D of the pressing roller 46. In addition, in this embodiment, when attaching the band-shaped pad S, the base 10 is moved in the direction of the arrow X2 by using only the moving speed of the robot arm 80 and the band-shaped pad S is attached. Can be fast.

In the present embodiment, the free end of the band-shaped pad S is fed below the pressing roller 46 by the feed roller 2 driven by the driving motor 7, so that the free end of the band-shaped pad S is also fed. Since the arrival at the lower side of the pressing roller 46 is detected by the photoelectric sensor, the accuracy of the sticking start position is good. In this embodiment, if the release paper S1 taken up by the take-up reel 3 is removed from the base 10 together with the take-up reel 3, and the release paper S1 is attached to a release paper automatic sticking machine for applying release paper to a double-sided tape, the release paper S1 is removed. It is advantageous for recycling.

In addition, according to the present embodiment, when the band-shaped pad S is not stuck, the pressing roller 46 rises and stands by. Then, the band-shaped pad S is attached by the pressing roller 46 that has been lowered in the direction of the arrow Y2. Therefore, if the pressing roller 46 is raised in the direction of the arrow Y1 to be on standby while the robot arm 80 moves the belt-shaped pad attaching apparatus 1 to the next attaching place, the driving gear 70 can be understood from FIG.
And the switching gear 65 mesh with each other, so that the driving force of the driving motor 7 is transmitted to the feed roller 2 so that the automatic feeding of the belt-shaped pad S can be performed during the above transition. Also, as the pressing roller 46 is lowered, the driving force of the driving motor 7 is
The automatic feeding of the band-shaped pad S can be stopped.

(Another Example) FIG. 10 shows another example. FIG.
The release paper S1 separated from the belt-shaped pad S may be wound up by the take-up reel 3 via the pad running surface 13a of the fixed guide 13 as shown in FIG. In this case, the release paper S1 contacts the fixed guide 13 with the pad running surface 13a of the fixed guide 13. That is, the adhesive surface S5 of the band-shaped pad S is
Is not touched by the pad running surface 13a. for that reason,
The non-adhesive coating film on the pad running surface 13a of the fixed guide 13 can be made unnecessary. In this example, the blade body 42 is set so that only the main body of the band-shaped pad can be cut without cutting the release paper S1.

Further, in the examples shown in FIGS. 1 to 8 described above, the base 10 is connected to the robot arm 80 and the base 10 is moved by moving the robot arm 80. However, the present invention is not limited to this.
May be moved along the sticking locus. In this case, when the standing wall N1 of the moving workpiece N approaches the fixed base 10, the workpiece N is moved up and down by the operation of the robot arm 80 to avoid collision. Further, the cylinder 17 is operated to move the pressing roller 46 to the arrow Y.
By moving the pressing roller 46 and the base 10 in two directions, the pressing roller 46 and the base 10 are relatively separated from each other along the direction in which the standing wall portion N1 stands. Thereby, similarly to the above-described embodiment, the band-shaped pad S can be stuck to the vicinity of the standing wall portion N1.

Further, a motor mechanism may be employed in place of the air cylinder 17 for elevating and lowering the pressing roller 46 used in the above example. Further, instead of the robot 8 used in the above-described example, a three-dimensional operating mechanism that can move the workpiece N three-dimensionally on the base 10 may be adopted. Further, the transmission of the driving force between the feed roller 2 and the pressing roller 46 at other locations may be performed by a gear, a belt, a chain, or the like.
It is clear that roller transmission may be used. The work is not particularly limited, and can be appropriately selected such as a packaging box, machinery, and electric components.

A band-shaped pad sticking device having a drive unit for moving away from each other in the standing direction, and one of the band-shaped pad sticking device and the work is held, and the band-shaped pad sticking device and the work are arranged along the surface to be stuck on the work. An operation mechanism (for example, a robot) having a three-dimensional operation part (for example, a robot arm) for relatively moving the object, and a pressing body of the band-shaped pad sticking device is landed on a surface to be stuck on the work, and the adhesive surface of the band-shaped pad is pressed with the work. On the surface to be pasted When the base of the band-shaped pad sticking device and the standing wall of the work approach each other, a command to relatively separate the base and the pressing body along the standing direction of the standing wall is output to the driving unit and the operating mechanism. A pad pasting machine comprising:

[0048]

According to the first and second aspects of the present invention, even when there is an upright wall in the vicinity of the surface to which the work is to be attached, the pressing body is kept in contact with the surface to which the work is to be applied. And the base are relatively separated from each other along the standing direction of the standing wall,
Interference and collision between the base having the feeding section and the standing wall can be avoided. Therefore, the band-shaped pad can be stuck to a position where the pressing body approaches the standing wall portion.

[0049] In the second aspect, by the operation of the clutch mechanism, excessive tension on the release paper is suppressed. Therefore, breakage of the release paper is prevented.
