Description

TECHNICAL FIELD The present invention relates to an interior material attaching jig used when attaching a sheet-like interior material to an interior surface of a vehicle.

The interior surface of the vehicle (ceiling surface, wall surface, floor surface, etc.) is provided with an interior material that has a sound insulation function that makes it difficult for rain striking sounds to travel from the outside of the vehicle to the vehicle interior, and a heat insulation function to prevent condensation and improve cooling and heating performance. Various sheet-shaped interior materials, such as the interior materials that the user has, are attached. Such an attachment of the interior material is usually performed by a worker getting into the vehicle by hand or by using a large facility such as a robot from outside the vehicle.

The manual work by the worker to attach the interior material to the ceiling surface of the vehicle is performed through the following procedure, for example. First, an operator grips an interior material having an adhesive applied on one side with fingers and positions it on the ceiling surface. Next, the worker presses the positioned interior material with fingers to the ceiling surface. Further, the operator sticks the entire surface of the large-sized interior material by pressing it against the ceiling surface while spreading the interior material with fingers. While such manual work is performed while the worker presses the interior material directly against the ceiling surface with his or her fingers, the attachment is highly reliable, but the work is time-consuming and the worker maintains an upward posture. Since it is performed as it is, there is a problem that the burden on the operator is heavy.

Therefore, in order to solve such a problem, it is preferable to perform the above-mentioned work by using a large facility such as a robot disclosed in Patent Document 1 below. In this case, the work can be performed by attaching a mold having a mounting surface for the interior material to the tip of the arm of the robot. That is, the robot arm is controlled so as to press the interior material on the mounting surface into the vehicle through the opening of the vehicle and then press the interior material against the ceiling surface.

JP, 7-76290, A

However, when the above mold is used as a jig, the burden on the operator can be kept low, but the following problems may occur.
That is, if the robot arm itself is moved to press the interior material against the ceiling surface, the pressing force of the interior material against the ceiling surface will not be stable, and the displacement of the interior material with respect to the formwork and the displacement of the interior material with respect to the ceiling surface will not occur. Since it is likely to occur, the attachment reliability when attaching the interior material to the ceiling surface is low. Such a problem may occur not only in the interior material for the ceiling surface, but also in the work of attaching the interior material to other indoor surfaces such as wall surfaces and floor surfaces.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an interior material attaching jig effective for increasing the attachment reliability when attaching a sheet-like interior material to the interior surface of a vehicle. To do.

The ceiling surface 2 is one of the indoor surfaces such as the wall surface and the floor surface. In this vehicle assembly line L, the vehicle 1 is transported in the transport direction which is the front FR of the vehicle while being supported from below by the pedestal 5 fixed to the transport surface 4a of the transport vehicle 4.

The interior material W is a sheet-shaped member that has both a sound insulation function of preventing rain hammering from being transmitted from the exterior of the vehicle to the interior of the vehicle and a heat insulation function of preventing dew condensation and improving cooling and heating performance. In the present embodiment, as an example of the interior material W, a material formed by compressing a soft material such as a quilting material or a sponge and formed into a sheet (an interior material called a so-called "roof silencer") is described. ..

The sticking device 10 includes a main body base 11, a robot 12 provided on the main body base 11, and an interior material sticking jig (hereinafter, simply referred to as a “jig”) attached to a tip portion 13a of an arm 13 of the robot 12. )20 and the control apparatus 60.

The jig 20 is a jig used when the interior material W is attached to the interior surface 2 of the vehicle 1. The jig 20 is controlled by the controller 60 together with the robot 12. The control device 60 is a known control device including an input/output unit that inputs and outputs control signals, an arithmetic processing unit that performs arithmetic processing, and a storage unit that stores input data and arithmetic results.

The main body base 11 is configured to travel on the parallel running surface 6 extending along the transport surface 4a of the transport vehicle 4 in synchronization with the vehicle 1 during a preset synchronization period. Therefore, the robot 12 also travels in synchronization with the vehicle 1. A storage rack 8 for stacking and temporarily storing a plurality of interior materials W is installed on the installation surface 7 adjacent to the parallel running surface 6.
Although only one storage rack 8 is shown in FIG. 1, when a plurality of types of interior materials W are used, a plurality of storage racks 8 prepared for each type of interior material W are installed on the installation surface. 7 is preferably installed.

The robot 12 is configured as a multi-joint robot having a plurality of axes. Although not shown in particular, each axis is provided with an electric motor as an actuator, which is controlled by the control device 60. Therefore, the position of the tip portion 13a of the arm 13 of the robot 12, that is, the position of the jig 20 can be changed by the control device 60 controlling the drive of the electric motor of each axis.

According to the sticking device 10 described above, the desired interior material W is first taken out from the storage rack 8 under the control of the robot 12. That is, the robot 12 is controlled so that the jig 20 moves from the first position P1 toward the uppermost interior material W of the plurality of interior materials W stacked on the storage rack 8. Then, the jig 20 is controlled so as to hold the uppermost interior material W. A specific structure for the jig 20 to hold the interior material W will be described later.

Next, the robot 12 is controlled so that the jig 20 holding the interior material W is arranged at the second position P2 corresponding to the coating device (not shown). Then, an adhesive is applied to one surface Wa of the interior material W by an application device. As a result, the adhesive layer A is formed on the surface Wa of the interior material W.

Next, the robot 12 is controlled so that the jig 20 holding the interior material W coated with the adhesive is introduced into the vehicle through the opening 3 of the vehicle 1. Then, the robot 12 moves so that the jig 20 moves from the third position P3 where the adhesive layer A of the interior material W faces the ceiling surface 2 to a position in the ceiling surface 2 that is close to the target surface 2a. Controlled. After that, the jig 20 is controlled to perform the work of attaching the interior material W to the target surface 2a.

Here, a specific structure of the jig 20 will be described with reference to FIGS. 2 to 9.

As shown in FIG. 2, the jig 20 supports two frame members 21 and 22 which are slidable relative to each other so as to change the separation distance in a state where they are arranged in parallel with each other, and support these frame members 21 and 22. And a supporting portion 23 for The support portion 23 includes a base member 24, two fixed members 25 and 25, and two movable members 26 and 26.

The base member 24 is provided with two rail portions 24a that are separated from each other in the second direction Y and extend parallel to each other. The rail portion 24a is formed with teeth such as a rack gear forming a so-called "rack and pinion". The tip portion 13 a of the arm 13 of the robot 12 is attached to the base member 24. It is preferable that the base member 24 is designed compact as a whole by reducing or eliminating a portion other than the rail portion 24a in order to reduce the weight of the jig 20.

The fixing member 25 is fixed to the upper surface of the base member 24. The two fixing members 25, 25 are arranged on the upper surface of the base member 24 so as to be separated from each other in the second direction Y. On the other hand, the movable member 26 is provided on each of the two rail portions 24a of the base member 24 and is engaged with each rail portion 24a so as to be able to travel.

The frame member 21 is a prism-shaped member that is fixed by bridging both ends of the two fixing members 25, 25. Two holding portions 30 and three pressing portions 40 are provided on the upper surface of the frame member 21.

The frame member 22 is a prism-shaped member that is fixed by bridging both ends of the two movable members 26, 26. Three pressing portions 40 are provided on the upper surface of the frame member 22, and the holding portion 30 is not provided.

As shown in FIG. 3, the movable member 26 includes a circular gear 27 such as a pinion that constitutes a so-called “rack and pinion”, and teeth on the outer periphery of the circular gear 27 have rail portions 24 a of the base member 24. It is configured to mesh with the teeth of. A frame member drive unit 28 is provided on the movable member 26.

The frame member driving unit 28 has a function of driving one frame member 22 so that the two frame members 21 and 22 relatively slide. In order to realize this function, the frame member driving unit 28 is configured by an electric actuator such as an electric motor that can rotate the circular gear 27 about a rotation shaft 27a, which is not particularly shown.

Therefore, the frame member driving unit 28 drives the circular gear 27 according to the control signal output from the control device 60. Therefore, the movable member 26 can travel on the rail portion 24 a of the support member 24 by rotating the circular gear 27 about the rotation shaft 27 a. At this time, the rotational movement of the circular gear 27 is converted into the linear movement of the movable member 26, and the frame member 22 slides with respect to the frame member 21 in the first direction X.

The frame member drive unit 28 may be a dual-purpose actuator that simultaneously drives both of the two circular gears 27, 27, or may be a dedicated actuator that drives only one circular gear 27. Good. An actuator other than an electric actuator may be used as the frame member driving unit 28.

As shown in FIG. 4, the movable member 26 reciprocates on the rail portion 24 a of the base member 24 by the frame member driving unit 28 switching the rotation direction of the circular gear 27. At this time, the frame member 22 moves integrally with the movable member 26, and can slide between the close position Q1 and the separated position Q2 while maintaining the parallel state with the frame member 21.

Here, the proximity position Q1 of the frame member 22 is a position closest to the frame member 21, that is, a position where the distance from the frame member 21 in the first direction X is relatively small. On the other hand, the separated position Q1 of the frame member 22 is a position most separated from the frame member 21, that is, a position where the separated distance from the frame member 21 in the first direction X is relatively large.

The holding portion 30 shown in FIG. 5 is configured to be able to hold the interior material W from the other surface Wb side when the one surface Wa of the interior material W is used as a bonding surface. The holding unit 30 drives a plurality of (four in FIG. 5) needles 33 for piercing and holding the interior material W, and drives the plurality of needles 33 in an oblique direction with respect to the extending surface of the interior material W. And a needle driving unit 34 that operates.

The plurality of needles 33 are built in the case 31 having a mounting surface 31a on which the interior material W is mounted, and project out of the case 31 through needle holes 32 formed in the mounting surface 31a of the case 31. Is configured. According to this configuration, the holding portion 30 for holding the interior material W can have a simple and compact structure that utilizes the forward/backward movement of the needle 33. Each of the plurality of needles 33 includes two first needles 33a and two second needles 33b having different projecting directions.

As shown in FIG. 6, all of the plurality of needles 33 are driven by the needle driving unit 34 between the storage position R1 and the protruding position R2. At this time, the two first needles 33a of the plurality of needles 33 are configured to move on a virtual directional line L that is inclined with respect to the mounting surface 31a of the case 31. On the other hand, the two second needles 33b of the plurality of needles 33 are inclined on the mounting surface 31a of the case 31 and move on the virtual direction line M intersecting the direction line L. It is configured. That is, the holding portion 30 is configured such that the advancing/retreating direction of the first needle 33a and the advancing/retreating direction of the second needle 33b are different.

According to this configuration, both the first needle 33a and the second needle 33b have a function as a retainer that restricts the removal operation of the interior material W in a state where the interior material W is pierced and held at the protruding position R2. Demonstrate. At this time, the needles 33a and 33b can hold (also referred to as “grasping”) the interior material W so as to grip the interior material W from the front surface Wb side.

The needle drive unit 34 is configured as an actuator that combines an air cylinder (not shown) capable of supplying air and a spring that elastically biases the needle in the retracting direction. According to this configuration, the plurality of needles 33 project from the mounting surface 31a of the case 31 by the pressure when the air is supplied from the air cylinder, while the case 31 is mounted by the elastic biasing force of the spring when the air supply is stopped. It operates to retract from the surface 31a.

The needle drive unit 34 may be a dual-purpose actuator that simultaneously drives both the two holding units 30 and 30 in FIG. 2, or a dedicated actuator that drives only one holding unit 30. It may be. An actuator other than the actuator in which the air cylinder and the spring are combined can be used as the needle driving unit 34.

The storage position R1 is a position where the tip of the needle 33 is retracted below the mounting surface 31a of the case 31. Therefore, when the plurality of needles 33 are set to the storage position R1, the interior material W placed on the mounting surface 31a of the case 31 is not held by the plurality of needles 33. That is, the holding of the interior material W by the plurality of needles 33 is released.

On the other hand, the protruding position R2 is a position where the tip of the needle 33 protrudes above the mounting surface 31a of the case 31. Therefore, when the plurality of needles 33 are set to the protruding position R2, the interior material W placed on the mounting surface 31a of the case 31 is held by being pierced by the plurality of needles 33.

For a more specific structure of the holding unit 30, refer to, for example, “Pneumatic needle gripper” disclosed in Japanese Patent Laid-Open No. 2011-173727.

The pressing unit 40 shown in FIG. 7 has a function of pressing the interior material W held by the holding unit 30 against the ceiling surface 2 of the vehicle 1 from the front surface Wb side. In order to realize this function, the pressing unit 40 drives the movable body 43, a cylindrical case 41, a movable body 43 that is reciprocally mounted in a through hole 41a provided in the case 41 in a vertically reciprocating manner. And a movable body drive unit 45 for

The movable body 43 is configured as a pinton member having two disc-shaped plate portions 43b and 43c at both ends of a columnar shaft portion 43a. The shaft portion 43a is configured such that its shaft diameter is slightly smaller than the hole diameter of the through hole 41a of the case 41. Both of the two plate portions 43b and 43c are configured such that their diameter exceeds the shaft diameter of the shaft portion 43a. As a result, the movable body 43, when attached to the case 41, can reciprocate in the third direction Z with a stroke corresponding to the axial length of the shaft portion 43a with respect to the case 41. The movable body 43 includes a permanent magnet 44 as a magnetic body on the lower plate portion 43c. The permanent magnet 44 is arranged on the plate portion 43c so that the lower surface side has an N pole.

The movable body driving section 48 drives the movable body 43 so as to be able to move back and forth in the third direction Z, which is the thickness direction of the interior material W, by changing the direction of the magnetic field acting on the permanent magnet 44 provided on the movable body 43. Have the function to In order to realize this function, the movable body driving unit 45 includes a magnet member 46 arranged to face the movable body 43, and an actuator 49 provided on the magnet member 46.

The magnet member 46 is accommodated in the engagement groove 42 provided in the case 41 so as to be capable of reciprocating in the horizontal direction. The magnet member 46 is a flat plate-shaped member having a permanent magnet 47 for attraction and a permanent magnet 48 for repulsion, which are arranged side by side in an orthogonal direction (first direction X) orthogonal to the forward/backward direction (third direction Z) of the movable body 43. Is configured as. The attraction permanent magnet 47 has an S pole on the side of the facing surface 46a of the magnet member 46 that faces the N pole of the permanent magnet 44 of the movable body 43. On the other hand, in the repulsive permanent magnet 48, the facing surface 46a side of the magnet member 46 is the N pole. An actuator 49 is connected to one end of the magnet member 46 in the first direction X.

The actuator 49 is configured to urge the magnet member 46 to reciprocate in the orthogonal direction (first direction X) in response to a control signal output from the control device 60. The actuator 49 is configured as an electric actuator such as an electric cylinder that linearly drives the magnet member 46 (not shown). Alternatively, an air-driven actuator can be used.

As shown in FIG. 8, the pressing portion 40 has a permanent magnet for attraction on the magnet member 46 side below the permanent magnet 44 on the movable body 43 side in a state where the magnet member 46 is set to the first position S1 by the actuator 49. The magnet 47 is arranged. At this time, the N pole of the permanent magnet 44 and the S pole of the attraction permanent magnet 47 attract each other by magnetic force, so that the movable body 43 is biased downward, and the upper plate portion 43b contacts the upper surface of the case 41. The suction position T1 is set in contact with the suction position.

On the other hand, as shown in FIG. 9, the pressing portion 40 has the magnet member 46 below the permanent magnet 44 on the movable body 43 side in a state where the magnet member 46 is set to the second position S2 by the actuator 49. The repulsion permanent magnet 48 on the side is arranged. At this time, the N pole of the permanent magnet 44 and the N pole of the repulsion permanent magnet 48 repel each other due to the magnetic force, so that the movable body 43 is biased upward, and the upper plate portion 43b is attached to the upper surface of the case 41. Is set to a repulsion position T2 which is separated upward from.

As described above, the movable body 43 reciprocates between the suction position T1 and the repulsion position T2 in conjunction with the operation of the magnet member 46 reciprocating between the first position S1 and the second position S2. It is configured.

Next, with reference to FIGS. 10 to 13, an operation of attaching the interior material W to the ceiling surface 2 of the vehicle 1 using the jig 20 will be described.

As shown in FIG. 10, first, the jig 20 is transported to the storage location (see the storage rack 8 in FIG. 1) by the control of the robot 12, and the interior material W is held by the jig 20. At this time, the jig 20 is arranged such that the holding portion 30 faces the uppermost interior material W of the plurality of interior materials W stacked and stored in the storage location. Then, after the holding portion 30 of the jig 20 is pressed against the surface Wb of the interior material W, the needle driving portion 34 drives the plurality of needles 33 to the protruding position R2.

Thereby, the plurality of needles 33 can pierce and hold the interior material W from the front surface Wb side. At this time, since the interior material W is made of a soft material, the needle 33 can easily pierce the interior material W. Further, the jig 20 is effective for easily taking out and conveying the uppermost interior materials W one by one when a plurality of interior materials W are stacked and stored.

As described above, instead of transporting the jig 20 to the storage location of the interior material W, an operator may manually set the interior material W directly on the jig 20.

As shown in FIG. 11, this jig 20 has an opening 3 (see FIG. 1) of the vehicle 1 under the control of the robot 12 in a state where the adhesive layer A is formed on the surface Wa of the interior material W being held. ) Is carried into the car. Then, the jig 20 is arranged such that the adhesive layer A of the interior material W faces the target surface 2a of the ceiling surface 2, and the interior material W is controlled by the robot 12 at the reference position of the target surface 2a. Is aligned with.

Thereafter, as shown in FIG. 12, in the jig 20, the holding unit 30 drives the plurality of needles 33 from the protruding position R2 to the storage position R1 by the needle driving unit 34, while the two frame members 21 and 22 are being driven. Each pressing unit 40 of the above drives the movable body 43 from the suction position T1 to the repulsion position T2 by the movable body drive unit 45.

As a result, the holding of the interior material W by the holding unit 30 is released, and the interior material W is pressed against the target surface 2a via the movable body 43 set to the repulsion position T2. At this time, since the frame member 22 is located close to the frame member 21, only the target surface 2a is attached to only a part of the surface Wa of the interior material W near the frame member 21.

Therefore, as shown in FIG. 13, the frame member drive unit 28 drives the frame member 22 from the proximity position Q1 to the separation position Q2 while the movable body 43 of the pressing unit 40 is maintained at the repulsion position T2. Accordingly, the interior material W is spread by tracing the target surface 2a by the cooperation of the pressing portion 40 and the frame member 22, and the entire front surface Wa is attached to the target surface 2a. At this time, the sliding operation of the frame member 22 can be automatically performed by the frame member driving unit 28.

It is preferable that the separated position Q2 of the frame member 22 be appropriately changed according to the size of the interior material W to be used. In this case, the frame member 22 slides with respect to the frame member 21 by a slide amount that corresponds to the size of the interior material W.

Next, the function and effect of the first embodiment will be described.

According to the jig 20 described above, the sheet-shaped interior material W can be held by the holding portion 30 from the front surface Wb side. Therefore, it is possible to prevent the positional deviation of the interior material W with respect to the jig 20 from occurring. Further, the interior material W held by the holding unit 30 can be pressed and attached to the target surface 2a by the pressing unit 40 while being aligned with the reference position of the target surface 2a of the ceiling surface 2. Therefore, it is possible to prevent the positional deviation of the interior material W with respect to the target surface 2a. In this case, the jig 20 can reproduce an operation close to the operation in which the operator holds the interior material W with fingers and presses it against the target surface 2a, and the interior material W can be reliably attached to a predetermined position. .. Therefore, when the sheet-shaped interior material W is attached to the ceiling surface 2 of the vehicle 1, the attachment reliability can be improved.

According to the jig 20 described above, since the movable body 43 is driven by using the magnetic force acting on the permanent magnet 44 that is a magnetic body in the pressing portion 40, the pressing force of the interior material W by the movable body 43 is stabilized. You can Further, the pressing portion 40 can have a simple and compact structure using the magnet member 46. Furthermore, since the two permanent magnets 47 and 48 that form the magnet member 46 are semi-permanently maintenance-free, the cost required for inspection and repair of the pressing portion 40 can be kept low.

According to the jig 20 described above, when the interior material W is attached to the ceiling surface 2, the frame member 22 is pressed against the frame member 21 by the pressing portion 44 provided on the frame member 22. It can be slid to increase the separation distance. At this time, it is possible to reproduce an operation close to the operation in which the operator directly operates the interior material W with fingers to spread it. As a result, it is possible to reduce the occurrence of so-called “sticking unevenness”, which is a non-uniform sticking state that may occur when the interior material W is stuck to the ceiling surface 2.
Further, the jig 20 has high versatility since it can be applied to a plurality of types of interior materials W having different sizes by adjusting the relative sliding amounts of the two frame members 21 and 22. ..

The jig 20 is used by being attached to the robot 12, and the interior material W can be automatically attached by using the three driving units 28, 34, and 45. It is possible to eliminate the burden on the operator when manually attaching the interior material W.

Hereinafter, another embodiment related to the first embodiment will be described with reference to the drawings. In other embodiments, the same elements as those of the first embodiment are designated by the same reference numerals, and the description of the same elements will be omitted.

(Embodiment 2)
As shown in FIG. 14, the jig 120 of the second embodiment is different from the jig 20 of the first embodiment in the structure of the support portion 123 that supports the two frame members 21 and 22. That is, the support portion 123 includes one fixed member 125 and one movable member 126, but does not include a member corresponding to the base member 24 of the first embodiment. Therefore, the tip portion 13a (see FIG. 1) of the arm 13 of the robot 12 is attached to the fixing member 125 of the jig 120.

The frame member 21 is fixed to the upper surface of the fixed member 125, and the frame member 22 is fixed to the upper surface of the movable member 126. A frame member drive unit 128 for sliding the frame member 22 between the close position Q1 and the separated position Q2 is attached to the fixed member 125. The frame member driving unit 128 is composed of an electric actuator such as an electric motor.

As shown in FIG. 15, the fixed member 125 includes an engaging convex portion 125 a at a portion facing the movable member 126. The engagement protrusion 125a is configured to slidably engage with an engagement groove 126a provided in the movable member 126 so as to extend in the first direction X. Therefore, the movable member 126 can be slid in the first direction X with respect to the fixed member 125 by the frame member driving unit 128.

Other configurations are similar to those of the first embodiment.

According to the jig 120 described above, since the supporting portion 123 is not provided with the member corresponding to the base member 24 of the first embodiment, the weight of the jig 120 itself can be reduced as compared with the jig 20 of the first embodiment. You can Further, in the state where the frame member 21 is slid to the proximity position Q1 so that the separation distance between the two frame members 21 and 22 becomes small, the outer shape of the jig 120 becomes small. Therefore, in this state, the jig 120 is easily carried in together with the interior material W from the opening 3 (see FIG. 1) of the vehicle 1.
In addition, the same effect as that of the first embodiment is obtained.

The present invention is not limited to the above-described typical embodiments, and various applications and modifications are conceivable without departing from the object of the present invention. For example, each of the following modes to which the above-described embodiment is applied can be implemented.

In the above embodiment, the case where only one frame member 22 of the two frame members 21 and 22 of the jigs 20 and 120 slides is illustrated, but the two frame members 21 and 22 are relatively slidable. It is sufficient that both of the two frame members 21 and 22 slide.

On the other hand, when the dimension of the interior material W to be attached is relatively small, the structure in which the two frame members 21 and 22 relatively slide can be omitted. In this case, only the holding portion 30 and the pressing portion 40 are used, and the interior material W held by the holding portion 30 is pressed against the indoor surface by the pressing portion 40 to be attached while being aligned with the reference position of the indoor surface. be able to.

In the above-described embodiment, the case where the holding unit 30 holds the interior material W by using the needle 33 has been illustrated, but as a means other than the needle 33, a means such as a suction pad, a magnet, or an adhesive tape may be used. it can.

In the above-described embodiment, the case where the pressing unit 40 presses the interior material W against the ceiling surface 2 using the permanent magnets 44, 47, 48 has been described as an example. However, as means other than the permanent magnets 44, 47, 48, electromagnets and It is also possible to use means such as an electric or air-driven actuator.

In the above embodiment, the case where the holding portion 30 is provided only on one frame member 21 of the two frame members 21 and 22 has been exemplified, but the holding portion 30 may be provided on both of the two frame members 21 and 22. You can Further, the number of holding portions 30 provided in each frame member can be appropriately selected according to the size of the target interior material W and the like.

In the above embodiment, the pressing portion 40 is provided on both of the two frame members 21 and 22, but the pressing portion 40 may be provided only on the frame member 22 where the holding portion 30 is not provided. .. Further, the number of pressing portions 40 provided on each frame member can be appropriately selected according to the size of the target interior material W and the like.

In the above-described embodiment, the jigs 20 and 120 used when the interior material W is attached to the ceiling surface 2 of the vehicle 1 have been exemplified, but these jigs 20 and 120 may be used, for example, like a wall surface or a floor surface. It can also be used when it is attached to an indoor surface different from the ceiling surface 2.

In the above embodiment, the jigs 20 and 120 attached to the robot 12 are described, but the structures of these jigs 20 and 120 are applied to the structure of the jigs that the operator can directly operate with his/her fingers. You can also do it. For example, in the jig 120 of the second embodiment, a structure in which the frame member driving unit 128 is omitted can be adopted. According to this structure, the interior material W can be spread by the operator sliding the frame member 22 with fingers. Here, when the worker spreads the interior material with his/her fingers, a difference in the sticking state is likely to occur due to a difference in the skill of the worker, etc. By adopting this structure, such a problem can be solved. ..
