Description

Technical Field

[0001] The present invention relates to a template positioning device.

Background Art

[0002] The hoistway of an elevator installed in a newly constructed building or the like is constructed according to the accuracy managed by the construction contractor. Currently, the elevator installation work is carried out in the following procedure. First, a plurality of piano wires are vertically installed from the ceiling portion of the hoistway. At this time, the piano wire is vertically suspended using a plumb bob. Next, using the position of the piano wire as the installation reference for the elevator, guide rails are laid in the hoistway, or a sill at the entrance on the hall side is installed.

[0003] As described above, when installing each device of the elevator, the piano wire is used as a reference for aligning the positions of the devices. The piano wire is attached to a mounting jig called a template and vertically installed in the hoistway. At that time, the operator needs to install the piano wire at a predetermined position from the reference ink marked by the construction contractor on the reference floor (usually the first floor). For this reason, the operator first performs scribing work from the reference ink on the reference floor and installs a scale so that a predetermined position can be specified on the reference floor. Next, the operator installs a template on the ceiling portion of the hoistway. Next, the operator attaches the upper end portion of the piano wire to the template, attaches a plumb bob to the lower end portion of the piano wire, and suspends the piano wire from the template. Next, the operator moves from the top floor of the hoistway to the reference floor to check the displacement of the piano wire from the predetermined position. Next, the operator moves from the reference floor to the top floor and adjusts the position of the template so that the piano wire approaches the predetermined position. Next, the operator moves from the top floor to the reference floor to check whether the position of the piano wire matches the predetermined position. After that, the operator repeatedly moves back and forth between the top floor and the reference floor to repeat the position adjustment of the template and the position confirmation of the piano wire, thereby aligning the piano wire with the predetermined position. In such a series of operations, the operator has to move up and down between the top floor and the reference floor many times and suffers physical fatigue.

[0004] As a technique for installing a piano wire inside an elevator hoistway, the technique described in Patent Document 1 is known. Patent Document 1 describes "a formwork support member installed at predetermined intervals in the horizontal direction at the top of the hoistway, a reference formwork provided in parallel along the landing side straddling between the formwork support members, with piano wire hanging parts provided at both ends, an X-axis direction positioning device provided at both ends of the reference formwork respectively, which independently adjusts and controls the planar movement in the direction orthogonal to the landing side at both ends of the reference formwork by a built-in motor, a Y-axis direction positioning device provided at the middle part of the reference formwork, which adjusts and controls the planar movement in the direction parallel to the landing side of the reference formwork by a built-in motor, a remote control device capable of remotely controlling the X-axis direction positioning device and the Y-axis direction positioning device by remote operation, a piano wire hanging down from the piano wire hanging parts at both ends of the reference formwork, with a weight attached to the lower end, and a water-filled container for weight stillness provided in the hoistway pit, which immerses the weight suspended from the lower end of the piano wire to suppress the pendulum movement of the weight", which is characterized as an automatic positioning device for an elevator reference formwork.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the technique described in Patent Document 1 has the following problems. Patent Document 1 describes setting a position adjustment mechanism (X-axis direction positioning device and Y-axis direction positioning device) for adjusting the position of a reference template to the reference template, and attaching this reference template to two support members (template support members). In this configuration, in order to continuously maintain the state of the reference template after position adjustment, the position adjustment mechanism needs to be attached to the support member while maintaining a predetermined length. Therefore, when installing each device of the elevator based on the position of the piano wire, it is necessary to keep the position adjustment mechanism attached to the support member until the installation work of all devices is completed. In addition, when proceeding with the installation work of elevator devices in parallel at multiple sites, it is necessary to align the number of position adjustment mechanisms with the number of work sites, and there is a problem that the utilization efficiency of the device deteriorates.

[0007] An object of the present invention is to provide a template positioning device capable of removing a position adjustment mechanism from a support member while keeping a template supported by the support member after adjusting the position of the template by the position adjustment mechanism.

Means for Solving the Problem

[0008] To solve the above problems, for example, the configuration described in the claims is adopted. This application includes a plurality of means for solving the above problems. If one of them is mentioned, it is a template positioning device that is supported by a plurality of support members installed in a hoistway and positions a template to which the upper end of a piano wire is attached. This template positioning device is detachable from the template, and includes a gripping member that grips the template and moves integrally with the template, and a position adjustment mechanism that adjusts the position of the template gripped by the gripping member by moving the gripping member integrally with the template. The position adjustment mechanism includes a first drive unit that moves the gripping member in a first direction, a second drive unit and a third drive unit that move the gripping member in a second direction orthogonal to the first direction, and a gantry that is detachable from the support member and supports the second drive unit and the third drive unit.

Effect of the Invention

[0009] According to the present invention, after adjusting the position of the template by the position adjusting mechanism, the position adjusting mechanism can be removed from the support member while the template is supported by the support member. Problems, configurations, and effects other than those described above will be clarified by the description of the following embodiments.

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same function or configuration are denoted by the same reference numerals, and redundant descriptions are omitted.

[0012] FIG. 1 is a schematic side view showing a state in which a template positioning device according to an embodiment is installed in an elevator hoistway. In the present embodiment, in order to clarify the shape and positional relationship of each part, when an operator stands in the elevator hall and views the elevator entrance from the front, the left - right direction is the X - axis direction, the depth direction is the Y - axis direction, and the up - down direction (vertical direction) is the Z - axis direction. The X - axis direction, Y - axis direction, and Z - axis direction are directions orthogonal to each other.

[0013] As shown in FIG. 1, the template positioning device 10 is a device that includes a position adjustment mechanism (described later) for adjusting the position of the template 1 and positions the template 1 by this position adjustment mechanism. The template positioning device 10 is used by being attached to the ceiling portion (top) of the hoistway 11. The positioning of the template 1 is performed to align the position of the piano wire 7 suspended from the template 1 using the weight 9 with a predetermined position.

[0014] In a building under construction, a workbench 12 is installed on the top floor of the hoistway 11. The workbench 12 is also called a top stage. An operator 13 rides on the workbench 12 to perform predetermined work. At the entrance of each floor of the hoistway 11, a curtain 14 for ensuring the safety of the operator 13 is installed. Further, on the ceiling portion of the hoistway 11, as an example of a support member, two (see FIG. 4) support pipes 15 are installed. The two support pipes 15 are arranged parallel to each other. Also, each support pipe 15 is installed horizontally using a spirit level (not shown). Regarding the parallelism and horizontality of the two support pipes 15, it is sufficient that the accuracy is ensured to the extent that there is no hindrance when positioning the template 1 using the positioning device 10. Also, the number of support pipes 15 is not limited to two and may be three or more.

[0015] Each support pipe 15 is formed in a cylindrical shape. As the support pipe 15, a steel pipe called a single-pipe can be used. At one end of the support pipe 15, a screw-type telescopic portion 15a is provided. The telescopic portion 15a changes the overall length of the support pipe 15 by expanding and contracting in the central axis direction of the support pipe 15. Also, an operation lever 16 and a butting plate 17 are provided at one end of the support pipe 15, and a butting plate 18 is provided at the other end of the support pipe 15. The operation lever 16 is a lever for rotating a nut that meshes with a screw formed in the telescopic portion 15a (not shown) around the central axis of the support pipe 15. When the operation lever 16 is rotated in one direction, the telescopic portion 15a extends, and when the operation lever 16 is rotated in the opposite direction, the telescopic portion 15a contracts.

[0016] The support pipe 15 configured as described above is fixed using the front wall 11a and the rear wall 11b of the hoistway 11 as viewed from the elevator entrance and exit. Specifically, the butting plate 18 is butted against the wall 11a, and the butting plate 17 is butted against the wall 11b by rotating the operation lever 16. At that time, by rotating the operation lever 16 in the direction in which the telescopic portion 15a extends, the butting plate 17 is strongly pressed against the wall 11b. Thereby, the support pipe 15 can be fixed to the ceiling portion of the hoistway 11 in such a manner that the support pipe 15 is stretched between the two walls 11a and 11b. Also, by using a spirit level or a measuring instrument (not shown), the two support pipes 15 can be installed in parallel and horizontally.

[0017] On the two support pipes 15 installed in this way, a template 1 and a template positioning device 10 are attached. As shown in FIGS. 2 and 3, the template 1 is a C-shaped long member. More specifically, the template 1 has an upper wall portion 2, two side wall portions 3a and 3b, and two bottom wall portions 4a and 4b, and a groove 5 is formed between the two bottom wall portions 4a and 4b. The groove 5 is formed along the longitudinal direction of the template 1.

[0018] Two piano wires 7 are attached to one template 1. The two piano wires 7 are suspended from both ends of the template 1 at a predetermined reference dimension. For this reason, protrusions 6 for attaching the piano wires 7 are provided at both ends of the template 1. The protrusions 6 are fixed to the upper wall portion 2 of the template 1. The protrusion 6 has a male screw 6a. The male screw 6a of the protrusion 6 protrudes on the side opposite to the side wall portions 3a and 3b in the thickness direction of the upper wall portion 2. Further, a through hole 6b penetrating the central axis of the protrusion 6 is formed in the protrusion 6. The upper end portion of the piano wire 7 is attached to the protrusion 6 through this through hole 6b. The center-to-center distance between the two protrusions 6 in the longitudinal direction of the template 1 is set in accordance with the above-described reference dimension.

[0019] In addition, square bolts 8 (see FIG. 3) are inserted inside the template 1. Two square bolts 8 are inserted per one template 1. The square bolt 8 is a bolt for fixing the template 1 to a template fixture 24 (see FIG. 7) described later. The square bolt 8 integrally has a head portion 8a and a screw portion 8b. The head portion 8a is hooked on the bottom wall portions 4a and 4b. The screw portion 8b protrudes below the template 1 through the groove 5. The square bolt 8 can be freely positioned in the longitudinal direction of the template 1 without falling off from the template 1 due to the engagement with the bottom wall portions 4a and 4b.

[0020] The piano wire 7 is a hard steel wire having a diameter of about 0.5 mm. The operator 13 passes the piano wire 7 through the through hole 6b provided in the protrusion 6 of the template 1, makes a knot at the upper end portion of the piano wire 7, and hooks the knot above the through hole 6b, thereby fixing the upper end portion of the piano wire 7 to the template 1. Further, the operator 13 attaches a weight 9 to the lower end portion of the piano wire 7, and vertically suspends the piano wire 7 by utilizing the gravity applied to the weight 9. The operator 13 uses a light weight when suspending the piano wire 7 attached to the template 1 from the top floor to the reference floor of the hoistway 11, and then replaces it with the heavy weight 9 at the reference floor.

[0021] FIG. 4 is a perspective view showing the configuration of the template positioning device according to the embodiment. As shown in FIG. 4, the template positioning device 10 includes a gripping member 20 that grips the template 1 and a position adjustment mechanism 22 that adjusts the position of the template 1 gripped by the gripping member 20. The constituent members of the template positioning device 10 are connected to each other integrally and can be attached to and detached from the support pipe 15 by a pedestal fixture 70 described later. The gripping member 20 is detachable from the template 1. Further, the gripping member 20 moves integrally with the template 1 while gripping the template 1. The position adjustment mechanism 22 adjusts the position of the template 1 by moving the gripping member 20 integrally with the template 1. Hereinafter, the configuration of each part of the template positioning device 10 will be described in detail.

[0022] (Gripping member 20) As shown in FIG. 5, the gripping member 20 has a first gripping member 25, a second gripping member 26 fixed to the first gripping member 25, and a leaf spring 27 attached to the second gripping member 26. The first gripping member 25 is a long member that is long in the longitudinal direction of the template 1. The first gripping member 25 integrally has a top plate portion 25a and a pair of side plate portions 25b, and is formed in a substantially U shape when viewed from the longitudinal direction of the template 1. The pair of side plate portions 25b face each other with a distance longer than the short-side dimension of the template 1. Each of the pair of side plate portions 25b is provided with two through holes (not shown) and two screw holes 28. The two through holes are holes for fixing the second gripping member 26 to the first gripping member 25. The two screw holes 28 are holes for attaching a gripping tool to the first gripping member 25. In the present embodiment, as an example of the gripping tool, a leaf spring 27 that is an elastic body is used. The leaf springs 27 are arranged at intervals in the longitudinal direction of the first gripping member 25. The leaf spring 27 is attached to one of the side plate portions 25b using a screw (not shown). Further, the leaf spring 27 is arranged so as to wrap from the outer surface side to the inner surface side of one of the side plate portions 25b. The leaf spring 27 has a pressing portion 27a that can be deformed by the elasticity of the leaf spring 27 itself. The pressing portion 27a is arranged to face the other side plate portion 25b.

[0023] The second gripping member 26 is a long member that is long in the longitudinal direction of the template 1. The longitudinal dimension of the second gripping member 26 is longer than the longitudinal dimension of the first gripping member 25. The second gripping member 26 is disposed inside the first gripping member 25. The second gripping member 26 integrally has a flat base portion 26a and a pair of wing portions 26b. In the longitudinal direction of the template 1 shown in FIG. 4, both ends of the base portion 26a protrude outward beyond both ends of the first gripping member 25. The pair of wing portions 26b are formed in a state of standing upright at right angles from the long side portions of the base portion 26a. Two screw holes (not shown) are provided in each of the pair of wing portions 26b. The second gripping member 26 is fixed to the first gripping member 25 using a total of four screws 29. Each screw 29 meshes with the screw hole of the wing portion 26b through the through hole of the side plate portion 25b.

[0024] The gripping member 20 having the above configuration forms a concave gripping space 30 by the pair of side plate portions 25b of the first gripping member 25 and the base portion 26a of the second gripping member 26. The gripping space 30 is a space for receiving and gripping the template 1, and the pressing portion 27a of the leaf spring 27 is disposed in the gripping space 30. The leaf spring 27 presses the template 1 received in the gripping space 30 by the pressing portion 27a, thereby pressing the template 1 against the other side plate portion 25b. As a result, the template 1 is sandwiched between the other side plate portion 25b and the leaf spring 27 in the short side direction of the template 1. Therefore, the template 1 can be gripped by utilizing the elastic force (biasing force) of the leaf spring 27.

[0025] In the present embodiment, screws 29 are used to fix the second gripping member 26 to the first gripping member 25, but the present invention is not limited thereto. For example, the second gripping member 26 may be fixed to the first gripping member 25 by welding or the like, or the two members may be fixed by other means.

[0026] In addition, in the present embodiment, the first gripping member 25 and the second gripping member 26 are combined to form the gripping member 20. However, the present invention is not limited to this, and the gripping member 20 may be formed as an integral structure, that is, a single member.

[0027] In addition, in the present embodiment, a leaf spring 27 is used as an example of the gripper. However, the present invention is not limited to this, and for example, a screw may be used. Specifically, instead of the leaf spring 27, wing screws (not shown) are respectively attached to the two screw holes 28 provided in one side plate portion 25b, and wing screws (not shown) are also respectively attached to the two screw holes 28 provided in the other side plate portion 25b. Then, using the four wing screws, the template 1 is gripped so as to sandwich the template 1 in the short side direction of the template 1. Further, when a screw is used as the holder, wing screws are respectively attached to the two screw holes 28 provided in either one of the pair of side plate portions 25b, and the template 1 may be gripped by pressing and sandwiching the template 1 against the other side plate portion 25b with the two wing screws. Further, the magnitude of the force with which the gripper grips the template 1 may be such that the template 1 can be moved together with the gripping member 20 within the XY coordinate plane.

[0028] (Position adjustment mechanism 22) As shown in FIG. 4, the position adjustment mechanism 22 includes a first drive unit 31 that moves the gripping member 20 in a first direction, a second drive unit 32 and a third drive unit 33 that move the gripping member 20 in a second direction orthogonal to the first direction, and a pedestal 34 that supports the second drive unit 32 and the third drive unit 33. The first direction corresponds to the X-axis direction in FIG. 4, and the second direction corresponds to the Y-axis direction in FIG. 4. The first drive unit 31, the second drive unit 32, and the third drive unit 33 are each constituted by a linear actuator. The linear actuator is an electric actuator that expands and contracts a rod using a motor such as a servo motor as a drive source. An electric actuator using a servo motor as a drive source is an actuator that can accurately control the amount of expansion and contraction of the rod according to a command signal such as the number of pulses or drive duty. The first drive unit 31 has a motor unit 31a, a case unit 31b, and a rod 31c. The case unit 31b incorporates a power conversion mechanism and a reduction gear that convert the rotational force generated by the motor unit 31a into the linear motion of the rod 31c. Similarly, the second drive unit 32 has a motor unit 32a, a case unit 32b, and a rod 32c, and the third drive unit 33 has a motor unit 33a, a case unit 33b, and a rod 33c.

[0029] The linear actuator used as the first drive unit 31, the second drive unit 32, or the third drive unit 33 is a preferred example for reducing the size and weight of the template positioning device 10. However, all or part of each drive unit (31, 32, 33) can also be configured using a drive mechanism other than the linear actuator. Examples of drive mechanisms other than the linear actuator include a ball screw mechanism.

[0030] The first drive unit 31 is attached to the gripping member 20. Specifically, the motor unit 31a and the case unit 31b of the first drive unit 31 are disposed on the top plate portion 25a of the first gripping member 25. Further, the case unit 31b of the first drive unit 31 is fixed to the top plate portion 25a of the first gripping member 25 using two fasteners 36. Each fastener 36 is screwed to the top plate portion 25a.

[0031] In addition, a linear motion mechanism 40 is mounted on the gripping member 20. The linear motion mechanism 40 is a mechanism that slidably supports the gripping member 20 in a predetermined direction along the longitudinal direction of the template 1 gripped by the gripping member 20. The linear motion mechanism 40 includes a first member 41 connected to the gripping member 20, a second member 42 connected to the second driving unit 32, and a third member 43 connected to the third driving unit 33. The first member 41, the second member 42, and the third member 43 are provided so as to be relatively movable in the predetermined direction.

[0032] As shown in FIG. 5, the first member 41 is attached to the upper surface of the base portion 26a of the second gripping member 26. The first member 41 is fixed to the base portion 26a by screwing. The first member 41 is a long member that is long in the longitudinal direction of the template 1. Both ends of the first member 41 protrude outward from both ends of the first gripping member 25, similar to both ends of the above-described base portion 26a. The longitudinal direction of the first member 41 is parallel to the longitudinal direction of the gripping member 20. The third member 43 is formed in a U shape when viewed from the longitudinal direction of the gripping member 20. The third member 43 is engaged with the first member 41. A predetermined number of steel balls (not shown) are incorporated in the engaging portion between the first member 41 and the third member 43, and the first member 41 and the third member 43 are relatively movably engaged by the rotation of these steel balls. The second member 42 is disposed on the side opposite to the third member 43 in the longitudinal direction of the gripping member 20. Also, the second member 42 has the same structure as the third member 43 and is engaged with the first member 41. Therefore, in the predetermined direction, the second member 42 and the third member 43 are guided by the first member 41 and can move independently. Also, in the predetermined direction, the first member 41 is guided by the second member 42 and the third member 43 and can move independently. Note that the first member 41 may be divided into two in the longitudinal direction of the base portion 26a, one first member 41 may be fixed to one end portion of the base portion 26a and engaged with the second member 42, and the other first member 41 may be fixed to the other end portion of the base portion 26a and engaged with the third member 43.

[0033] As shown in FIG. 4, a first rotary joint 51 and a second rotary joint 52 are attached to the second member 42. Further, a third rotary joint 53 is attached to the third member 43. The first rotary joint 51 is a joint that connects the first drive unit 31 to the second member 42. More specifically, it is a joint that rotatably connects the tip of the rod 31c of the first drive unit 31 to the second member 42. The second rotary joint 52 is a joint that connects the second drive unit 32 to the second member 42. More specifically, it is a joint that rotatably connects the tip of the rod 32c of the second drive unit 32 to the second member 42. The third rotary joint 53 is a joint that connects the third drive unit 33 to the third member 43. More specifically, it is a joint that rotatably connects the tip of the rod 33c of the third drive unit 33 to the third member 43. The second rotary joint 52 and the third rotary joint 53, together with the linear motion mechanism 40 described above, are elements that constitute a connecting portion. The connecting portion is a mechanism that connects the second drive unit 32 and the third drive unit 33 to the gripping member 20.

[0034] The first rotary joint 51, the second rotary joint 52, and the third rotary joint 53 basically have the same configuration. Hereinafter, the third rotary joint 53 will be described as an example. FIG. 6 is a longitudinal sectional view showing an example of a connection structure by the third rotary joint. As shown in FIG. 6, the third rotary joint 53 is fitted, for example, to a protruding pin 45 provided on an intermediate plate 55, and rotatably supports the tip of the rod 33c about the central axis J of the protruding pin 45. The third rotary joint 53 is fixed to the protruding pin 45, for example, by press-fitting or adhesion. The central axis of the third rotary joint 53 is coaxial with the central axis J of the protruding pin 45. The shaft portion of the third rotary joint 53 is inserted into a through-hole 46 for connection provided at the tip of the rod 33c. A collar or bearing may be attached to the through-hole 46 of the rod 33c as required. The intermediate plate 55 is a plate fixed to the upper surface of the third member 43. The protruding pin 45 is a pin that stands vertically from the upper surface of the intermediate plate 55. Note that the intermediate plate 55 is provided as required, and the protruding pin 45 may be provided directly on the third member 43.

[0035] On the other hand, two protruding pins (not shown) are provided on the second member 42 at intervals in the longitudinal direction of the second member 42. The first rotary joint 51 is fitted to one of the protruding pins, and the second rotary joint 52 is fitted to the other protruding pin. The first rotary joint 51 rotatably supports the tip of the rod 31c about the protruding pin to which the first rotary joint 51 is fitted, and the second rotary joint 52 rotatably supports the tip of the rod 32c about the protruding pin to which the second rotary joint 52 is fitted. Further, the gripping member 20 is swingable about the second rotary joint 52. The swinging operation of the gripping member 20 about the second rotary joint 52 is an operation for adjusting the inclination (posture) of the template 1 with respect to the X-axis direction.

[0036] The second drive unit 32 and the third drive unit 33 are attached to the gantry 34. Hereinafter, the configuration of the gantry 34 will be described in detail. As shown in Fig. 4, the gantry 34 is a structure that serves as the base of the template positioning device 10. The gantry 34 holds the gripping member 20, the position adjustment mechanism 22, the linear motion mechanism 40, etc., and is used to fix the entire template positioning device 10 to the two support pipes 15 via the gantry fixture 70. The gantry 34 includes two aluminum frames 60, two support plates 61, and two connecting plates 62.

[0037] The aluminum frame 60 is an elongated square bar-shaped frame. The length of the aluminum frame 60 is longer than the distance between the two support pipes 15 in the X-axis direction. Elongated grooves are formed on each of the four sides of the aluminum frame 60. The grooves in the aluminum frame 60 are grooves for passing nuts (not shown). The nuts inserted into the grooves of the aluminum frame 60 can move freely in the longitudinal direction of the aluminum frame 60. The aluminum frame 60 is arranged in a direction perpendicular to the support pipe 15 and spans between the two support pipes 15. Also, the two aluminum frames 60 are arranged parallel to each other.

[0038] The two support plates 61 are arranged at both longitudinal ends of the aluminum frame 60. Each support plate 61 is arranged to span between the two aluminum frames 60 and is fixed to the aluminum frame 60 using four screws 64. As a result, the two aluminum frames 60 are connected by the two support plates 61. The screws 64 mesh with nuts (not shown) inserted into the grooves on the upper surface of the aluminum frame 60. The support plate 61 is provided with holes (not shown) for passing the male screw portions of the screws 64. The nuts cannot rotate within the grooves of the aluminum frame 60. Therefore, by tightening each screw 64 with an appropriate torque, the support plate 61 can be firmly fixed to the aluminum frame 60. Thus, a robust gantry 34 can be obtained.

[0039] The two connecting plates 62 are arranged between the two support plates 61 in the longitudinal direction of the aluminum frame 60. Each connecting plate 62 is arranged to span between the two aluminum frames 60 and is fixed to the aluminum frame 60 using two screws 65. The screws 65 engage with nuts (not shown) inserted into the grooves on the upper surface of the aluminum frame 60. Then, the connecting plate 62 is fixed to the aluminum frame 60 by tightening the screws 65. Thereby, the two aluminum frames 60 are connected not only by the two support plates 61 described above but also by the two connecting plates 62.

[0040] In the gantry 34 having the above configuration, the two support plates 61 are used as plates for attaching the second drive unit 32 and the third drive unit 33 to the gantry 34. The motor unit 32a and the case unit 32b of the second drive unit 32 are arranged on one support plate 61. Also, the case unit 32b of the second drive unit 32 is fixed to one support plate 61 using two fasteners 66. Thread holes (not shown) are formed on the upper surface of the support plate 61, and each fastener 66 is screwed to the support plate 61 using these thread holes. Similarly, the motor unit 33a and the case unit 33b of the third drive unit 33 are arranged on the other support plate 61. Also, the case unit 33b of the third drive unit 33 is fixed to the other support plate 61 using two fasteners 67. Further, the second drive unit 32 and the third drive unit 33 are arranged parallel to each other.

[0041] Here, when the screws 64 fixing each support plate 61 to the aluminum frame 60 are loosened, the support plate 61 can be freely moved in the longitudinal direction of the aluminum frame 60. Therefore, in the longitudinal direction of the aluminum frame 60, the positions of the second drive unit 32 and the third drive unit 33 can be adjusted individually. Also, in the longitudinal direction of the aluminum frame 60, the distance between the second drive unit 32 and the third drive unit 33 can be adjusted to a desired distance.

[0042] The mount 34 can be equipped with a control device including a control circuit, a power source, etc. not shown in the figure. The control device can be fixed, for example, to two connecting plates 62 by screwing or the like. Also, the control device can be fixed to the aluminum frame 60 with the same structure as the connecting plate 62. The control device has a control unit (for example, a CPU) that controls the first drive unit 31, the second drive unit 32, and the third drive unit 33. The power source supplies power to the first drive unit 31, the second drive unit 32, and the third drive unit 33 respectively. The first drive unit 31, the second drive unit 32, the third drive unit 33, and the control device on the mount 34 are electrically connected via a cable not shown in the figure. By mounting the control device on the mount 34 in this way, the cable length for electrical connection can be shortened compared with the case where the control device is installed outside the template positioning device 10. Also, it is not necessary to draw out a cable outside the template positioning device 10 and connect this cable to an external control device. For this reason, the handling of the template positioning device 10 becomes easy.

[0043] (Mount fixture) The mount fixture 70 is a fixture that fixes the mount 34 to the support pipe 15. The mount 34 is configured to be detachable from the mount fixture 70. The mount fixture 70 is configured to be detachable from the support pipe 15.

[0044] The pedestal fixture 70 is composed of a flat plate portion 71 on which the pedestal 34 is placed and a clamp 72 that fixes this flat plate portion 71 to the support pipe 15. The flat plate portion 71 and the clamp 72 are fixed to each other by, for example, fastening with bolts and nuts or welding. The flat plate portion 71 is arranged in a state of facing the support plate 61 via the aluminum frame 60. The flat plate portion 71 is fixed to the aluminum frame 60 using screws and nuts, similar to the support plate 61. The nut for fixing the flat plate portion 71 to the aluminum frame 60 is inserted into a groove formed on the lower surface of the aluminum frame 60, and in a state where the screw is loosened, the flat plate portion 71 can move freely in the longitudinal direction of the aluminum frame 60. Therefore, even when the distance between the two support pipes 15 changes due to the building environment, the position of the flat plate portion 71 can be adjusted according to that distance, and the flat plate portion 71 can be fixed to the aluminum frame 60. Also, by removing the screw that fixes the flat plate portion 71 to the aluminum frame 60, the pedestal 34 can be removed from the pedestal fixture 70. The clamp 72 is configured using, for example, a single-pipe clamp. The single-pipe clamp is a clamp that can sandwich the support pipe 15 and be fixed to the support pipe 15 by the tightening force of bolts and nuts. The single-pipe clamp can be removed from the support pipe 15 by loosening the tightening of the bolts and nuts and opening the clamp.

[0045] (Template fixture) Furthermore, the template positioning device 10 according to the present embodiment includes a template fixture 24 that fixes the template 1 whose position has been adjusted by the position adjustment mechanism 22 to the support pipe 15. When the position of the template 1 is adjusted by the position adjustment mechanism 22, the template fixture 24 supports the template 1 so as to be movable in the horizontal plane.

[0046] Figure 7 is a perspective view showing the configuration of the template fixture. As shown in Fig. 7, the template fixture 24 is attached to each of the two support pipes 15. The template fixture 24 is composed of a receiving plate portion 75 that receives and supports the template 1 from below, and a fastener 76 that fixes the receiving plate portion 75 to the support pipe 15. The receiving plate portion 75 and the fastener 76 are fixed to each other by, for example, fastening with bolts and nuts, or welding. The receiving plate portion 75 is formed in a flat plate shape that is rectangular in plan view. The upper surface of the receiving plate portion 75 is a flat sliding surface 75a. The bottom surface of the template 1 held by the gripping member 20 is arranged in contact with the sliding surface 75a of the receiving plate portion 75. The sliding surface 75a is a surface that slidably supports the template 1 when the position of the template 1 is adjusted by the position adjustment mechanism 22.

[0047] A long hole 77 is formed in the receiving plate portion 75. The long hole 77 is a hole that is long in the Y-axis direction along the longitudinal direction of the support pipe 15. The long hole 77 is a hole for fixing the template 1 to the receiving plate portion 75. The template 1 is placed on the sliding surface 75a of the receiving plate portion 75 in a direction intersecting the long hole 77. At this time, the screw portion 8b of the square bolt 8 shown in Fig. 2 is inserted into the long hole 77 of the receiving plate portion 75. A nut (not shown) is engaged with the screw portion 8b from the lower surface side of the receiving plate portion 75. In a state where this nut is loosened, the template 1 can be freely moved on the sliding surface 75a while the weight of the template 1 is received by the receiving plate portion 75. Also, in a state where the nut is tightened, the template 1 can be fixed to the receiving plate portion 75. The fastener 76 is configured using, for example, a single-pipe clamp. The details of the single-pipe clamp are as described above.

[0048] Fig. 8 is a block diagram showing the control configuration of the template positioning device according to the embodiment. As shown in FIG. 8, the template positioning device 10 includes a remote controller (hereinafter also referred to as a “remote control”) 50 and a control device 80 that exchanges signals with the remote control 50. The remote control 50 has an antenna 50a for wireless communication. The control device 80 has an antenna 80a for wireless communication. As shown in FIG. 1, the remote control 50 is a device used by an operator 13 who checks the position of the piano wire 7 on the reference floor (the first floor in the illustrated example) of a building. The remote control 50 is a device for remotely operating the above-described position adjustment mechanism 22.

[0049] The control device 80 is a device that controls the first drive unit 31, the second drive unit 32, and the third drive unit 33 provided in the position adjustment mechanism 22. The control device 80 is preferably mounted on the gantry 34 as described above. The control device 80 receives a signal transmitted from the remote control 50 and controls the operation of the position adjustment mechanism 22 (the first drive unit 31, the second drive unit 32, and the third drive unit 33) according to the received signal.

[0050] Subsequently, the operation of the template positioning device 10 according to the embodiment will be described with reference to FIG. 9. In FIG. 9, the position of the template 1 held by the gripping member 20 is represented in the XY coordinate system. Also, reference symbol A in the figure indicates the position of the template 1 before position adjustment, and reference symbol B indicates the position of the template 1 after position adjustment. Here, for the sake of convenience of explanation, it is assumed that the longitudinal direction of the template 1 before position adjustment is parallel to the X-axis direction. Also, the piano wire 7 arranged on the left side of FIG. 9 is denoted by reference symbol 7L, and the piano wire 7 arranged on the right side of FIG. 9 is denoted by reference symbol 7R for explanation.

[0051] In Fig. 9, the coordinates (x0, y0) indicate the initial position of the left piano wire 7L, the coordinates (x1, y1) indicate the target position of the left piano wire 7L, and the coordinate y2 on the Y-axis indicates the target position of the right piano wire 7R in the Y-axis direction. Also, the arrow W1 in the figure indicates the moving direction and moving amount of the gripping member 20 when the first drive unit 31 is driven to extend the rod 31c. Further, the arrow W2 in the figure indicates the moving direction and moving amount of the gripping member 20 when the second drive unit 32 and the third drive unit 33 are simultaneously moved to extend the rods 32c and 33c by the same amount, and the arrow W3 indicates the moving direction and moving amount of the gripping member 20 when the third drive unit 33 is driven to extend the rod 33c. Also, the arrow K1 in the figure indicates the moving trajectories of the piano wires 7R and 7L when the gripping member 20 moves in the W1 direction by the drive of the first drive unit 31. Further, the arrow K2 in the figure indicates the moving trajectories of the piano wires 7R and 7L when the gripping member 20 moves in the W2 direction by the drive of the second drive unit 32 and the third drive unit 33, and the arrow K3 indicates the moving trajectories of the piano wires 7R and 7L when the gripping member 20 moves in the W3 direction by the drive of the third drive unit 33.

[0052] The template positioning device 10 is a device that positions the template 1 so as to align the left and right piano wires 7L and 7R with predetermined positions by moving the template 1 integrally with the gripping member 20 by driving the first drive unit 31, the second drive unit 32, and the third drive unit 33. As shown in Fig. 1, the template positioning device 10 is installed near the ceiling of the elevating path 11 where the template 1 is installed. On the other hand, the operator 13 remotely operates the template positioning device 10 using the remote controller 50 while checking the position of the piano wire 7 on the reference floor. Therefore, the operator 13 remotely operates the template positioning device 10 while checking the position of the piano wire 7 with the scale 90 so that the position of the piano wire 7 coincides with the predetermined position.

[0053] The operation of the template positioning device 10 will be described below with specific examples. In this specific example, it is assumed that the initial position of the piano wire 7L exists at the coordinates (x0, y0), and the initial position of the piano wire 7R on the Y-axis exists at y0. Also, it is assumed that the target position of the piano wire 7L exists at the coordinates (x1, y1), and the target position of the piano wire 7R on the Y-axis exists at y2. In such a case, the operator 13 who operates the remote controller 50 at the reference level operates the template positioning device 10 mainly in three steps.

[0054] In the first step, the operator 13 drives the first drive unit 31 by operating the remote controller 50 to move the coordinate position of the piano wire 7L on the X-axis from the initial position x0 to x1. At this time, the operator 13 measures the amount of movement required to move the piano wire 7L from the initial position x0 to x1 with the scale 90, and then transmits a command signal for driving the first drive unit 31 by that amount of movement from the remote controller 50. Then, the control device 80 receives the command signal transmitted from the remote controller 50 and drives the first drive unit 31 according to this command signal. As a result, the gripping member 20 moves in the X-axis direction according to the telescopic movement of the rod 31c of the first drive unit 31.

[0055] Here, both the first rotary joint 51 and the second rotary joint 52 are coupled to the second member 42 of the linear motion mechanism 40. Also, the second rotary joint 52 is coupled to the rod 32c of the second drive unit 32. Therefore, the movement of the second member 42 in the X-axis direction is restricted by the second drive unit 32. That is, the second member 42 cannot move in the X-axis direction. On the other hand, the first member 41 of the linear motion mechanism 40 is fixed to the second gripping member 26 of the gripping member 20. Further, the second member 42 and the third member 43 are engaged with the first member 41 so as to be relatively movable. Thus, when the first drive unit 31 is driven to expand and contract the rod 31c, the motor unit 31a and the case unit 31b of the first drive unit 31 move in a direction approaching and separating from the first rotary joint 51. At this time, the first member 41 is guided by the second member 42 and the third member 43 and moves in the X-axis direction. Also, since the case unit 31b of the first drive unit 31 is fixed to the first gripping member 25 of the gripping member 20 by the fastener 36, when the case unit 31b moves in a direction approaching and separating from the first rotary joint 51 as described above, the gripping member 20 moves integrally with the case unit 31b. Therefore, when the first drive unit 31 is driven to expand and contract the rod 31c, the gripping member 20 moves in the X-axis direction according to the expansion and contraction operation of the rod 31c. Thus, the template 1 held by the gripping member 20 can be moved in the X-axis direction integrally with the gripping member 20.

[0056] Note that the piano wire 7 is a pendulum suspending the weight 9. Therefore, when the template 1 is moved, the piano wire 7 sways. In such a case, the operator 13 removes the sway of the piano wire 7, for example, by pressing the piano wire 7 by hand or immersing the weight 9 in a bucket filled with liquid. And in the first step, with the sway of the piano wire 7L removed, it is confirmed that the piano wire 7L has reached the position of x1. Also, when the piano wire 7L is deviated from the position of X1, the operator 13 operates the remote controller 50 again to adjust the piano wire 7L to the position of x1 in order to correct the deviation.

[0057] In the second step, operator 13 moves the coordinate positions of the piano wires 7L and 7R on the Y-axis from the initial position y0 to y1 by simultaneously driving the second drive unit 32 and the third drive unit 33 by operating the remote controller 50. At this time, operator 13 measures the amount of movement required to move the piano wires 7L and 7R from the initial position y0 to y1 with the scale 90, and then transmits a command signal from the remote controller 50 to drive the second drive unit 32 and the third drive unit 33 by that amount of movement. Then, the control device 80 receives the command signal transmitted from the remote controller 50, and simultaneously drives the second drive unit 32 and the third drive unit 33 according to this command signal. As a result, the rod 32c of the second drive unit 32 and the rod 33c of the third drive unit 33 expand and contract by the same amount in the same direction. For this reason, the gripping member 20 moves parallel in the Y-axis direction according to the expansion and contraction movements of the rods 32c and 31c.

[0058] Here, the second drive unit 32 and the third drive unit 33 are fixed to the gantry 34. Further, the gantry 34 is fixed to the two support pipes 15 using two gantry fixtures 70. On the other hand, the rod 32c of the second drive unit 32 is connected to the second member 42 of the linear motion mechanism 40 by the second rotary joint 52, and the rod 33c of the third drive unit 33 is connected to the third member 43 of the linear motion mechanism 40 by the third rotary joint 53. Therefore, when the second drive unit 32 and the third drive unit 33 are simultaneously driven to expand and contract the rods 32c and 33c by the same amount in the same direction, the gripping member 20 moves parallel in the Y-axis direction according to the expansion and contraction movements of the rods 32c and 33c. Thus, the template 1 held by the gripping member 20 can be moved parallel in the Y-axis direction integrally with the gripping member 20. In this second step, operator 13, in the same manner as in the first step, confirms that the piano wire 7L has reached the position y1 with the sway of the piano wire 7L removed, and finally adjusts the piano wire 7L to the position y1. Note that since the position of the piano wire 7R is adjusted in the third step, the piano wire 7R may deviate from the position y1 at this stage.

[0059] In the third step, the operator 13 moves the coordinate position of the piano wire 7R on the Y-axis from y1 to y2 by driving the third drive unit 33 by operating the remote controller 50. At this time, the operator 13 measures the amount of movement required to move the piano wire 7R from y1 to y2 with the scale 90, and then transmits a command signal from the remote controller 50 to drive the third drive unit 33 by that amount of movement. Then, the control device 80 receives the command signal transmitted from the remote controller 50 and drives the third drive unit 33 according to this command signal. As a result, the gripping member 20 swings (rotates) about the second rotary joint 52 according to the telescopic movement of the rod 33c of the third drive unit 33. As a result, the inclination (posture) of the gripping member 20 with respect to the X-axis direction changes.

[0060] In the third step, since the rod 32c of the second drive unit 32 is not telescopically operated, the second rotary joint 52 stops at a fixed position. On the other hand, the position of the third rotary joint 53 moves in the Y-axis direction according to the telescopic movement of the rod 33c of the third drive unit 33. For this reason, in the third step, the gripping member 20 swings about the second rotary joint 52 according to the telescopic movement of the rod 33c. Therefore, the template 1 held by the gripping member 20 can be swung together with the gripping member 20. Further, when the template 1 is swung in this way, the piano wire 7R moves along an arc trajectory and reaches the position of y2.

[0061] Also, when the gripping member 20 swings around the second rotary joint 52, as shown in FIG. 10, the center-to-center distance (distance between fulcrums) L between the second rotary joint 52 and the third rotary joint 53 changes before and after the gripping member 20 swings. Specifically, in FIG. 10, when the gripping member 20 swings counterclockwise (ccw) around the second rotary joint 52, the center-to-center distance L between the second rotary joint 52 and the third rotary joint 53 increases by ΔL. At this time, since the second rotary joint 52 is in a state of stopping at a fixed position, the second member 42 to which the second rotary joint 52 is connected does not move. On the other hand, the third rotary joint 53 is connected to the third member 43. Also, the third member 43 is movably supported by the first member 41, and the first member 41 is fixed to the second gripping member 26. Therefore, when the gripping member 20 swings around the second rotary joint 52, the third member 43 moves by ΔL in the direction of arrow M. That is, the change in the center-to-center distance L accompanying the swing of the gripping member 20 is absorbed (allowed) by the movement of the third member 43. Therefore, the movement path of the third rotary joint 53 when the third drive unit 33 is driven in the third step becomes parallel to the Y-axis direction. Thus, the rod 33c of the third drive unit 33 can be smoothly extended and contracted.

[0062] In the third step, as shown in FIG. 9, when the template 1 swings (rotates) integrally with the gripping member 20, not only does the piano wire 7R move along an arc trajectory, but the piano wire 7L also moves along an arc trajectory. For this reason, the position of the piano wire 7L deviates from the position of y1 adjusted in the second step. However, the piano wire 7L is arranged closer to the second rotary joint 52 than the piano wire 7R in the longitudinal direction of the template 1. For this reason, the amount of movement of the piano wire 7L when the template 1 swings is smaller than the amount of movement of the piano wire 7R. Therefore, in the third step, after the operator 13 aligns the piano wire 7R with the target position y2 by operating the remote controller 50, the operator checks with the scale 90 how much the piano wire 7L has deviated from the target position y1. If the amount of deviation of the piano wire 7L is within the allowable value, the positioning of the template 1 is completed at that time. If the amount of deviation of the piano wire 7L exceeds the allowable value, the operations from the first step to the third step described above are performed again so that the amounts of deviation of the piano wires 7L and 7R are both within the allowable value, and the piano wires 7L and 7R are aligned with the target positions.

[0063] Subsequently, the operation procedure of the operator using the template positioning device 10 according to the embodiment will be described with reference to the flowchart of FIG. 11.

[0064] First, the operator 13 installs the support pipe 15 as follows (step S101). Operator 13 installs two support pipes 15 in parallel near the ceiling of the hoistway 11. At this time, operator 13 gets on the workbench 12, extends the first support pipe 15 between the front wall 11a and the rear wall 11b, generates a tension force between the walls 11a and 11b, and stretches the first support pipe 15. At this time, use a level to adjust the position of the support pipe 15 so that the support pipe 15 is horizontal. Next, operator 13 stretches the second support pipe 15 between the walls 11a and 11b in the same procedure as above. Also, operator 13 measures the distance between the two support pipes 15 so that the second support pipe 15 is parallel to the first support pipe 15, and adjusts the position of the second support pipe 15.

[0065] Next, operator 13 performs the installation work of template 1 as follows (step S102). After operator 13 attaches the template fixture 24 to the support pipe 15, operator 13 attaches template 1 to the template fixture 24. At this time, operator 13 attaches the template fixture 24 to each of the two support pipes 15. Specifically, operator 13 opens the clamp 76 of the template fixture 24, closes the clamp 76 by sandwiching the support pipe 15 inside the clamp 76. Next, operator 13 fixes the template fixture 24 to the support pipe 15 by tightening the clamp 76 with bolts and nuts. At this time, operator 13 fixes the template fixture 24 so that the sliding surface 75a of the receiving plate portion 75 is horizontal. Also, operator 13 determines the position to fix the template fixture 24 so that the position adjustment amount of template 1 is minimized. Next, while inserting the threaded portion 8b of the square bolt 8 protruding from the bottom surface of template 1 into the long hole 77 of the receiving plate portion 75, operator 13 places the bottom surface of template 1 on the sliding surface 75a of the receiving plate portion 75. After operator 13 performs such work individually with the two template fixtures 24, operator 13 moves template 1 near the center in the major axis direction of the long hole 77. Next, operator 13 temporarily fixes template 1 to the receiving plate portion 75 by engaging and tightening a nut with the threaded portion 8b of the square bolt 8 from the lower surface side of the receiving plate portion 75.

[0066] Next, worker 13 performs the installation work of the piano wire 7 as follows (step S103). Worker 13 attaches the piano wires 7 (7L, 7R) to both ends of the template 1. At this time, worker 13 passes the piano wire 7 through the through-hole 6b of the protrusion 6 provided at the end of the template 1, makes a knot in the piano wire 7 above the protrusion 6 so that the piano wire 7 does not come out of the through-hole 6b. At this time, worker 13 winds the excess wire above the knot of the piano wire 7 around the protrusion 6 or the like to more surely prevent the piano wire 7 from falling off. Next, worker 13 attaches a light weight to the end of the piano wire 7 extending below the template 1 and suspends the piano wire 7 to the reference floor. After worker 13 individually performs such work with the two piano wires 7 (7L, 7R), worker 13 moves from the top floor to the reference floor and replaces the light weight attached to the lower end of the piano wire 7 with the heavy weight 9.

[0067] Next, worker 13 performs the attachment work of the template positioning device 10 as follows (step S104). Operator 13 fixes the template positioning device 10 to the support pipe 15 and grips the template 1 with the gripping member 20. At this time, operator 13 gets on the top floor workbench 12 and adjusts the position of the pedestal fixture 70 of the template positioning device 10 to match the width between the support pipes 15. Next, operator 13 opens the clamp 72 of the pedestal fixture 70 and straddles the template positioning device 10 between the two support pipes 15. Next, operator 13 lifts the gripping member 20 of the template positioning device 10 and covers the template 1. Next, operator 13 determines the approximate position of the template positioning device 10. Next, operator 13 tightens the clamps 72 of the two pedestal fixtures 70 to fix the template positioning device 10 to the two support pipes 15. Next, operator 13 loosens the nut engaged with the above-described square bolt 8 to make the template 1 movable freely. Next, operator 13 accommodates the template 1 in the gripping space 30 of the gripping member 20 and holds the template 1 on the gripping member 20 by the leaf spring 27 provided on the gripping member 20. At this time, the template 1 is pressed against one side plate portion 25b by the repulsive force due to the deformation of the leaf spring 27. The gripping of the template 1 can be easily performed by a one-touch operation using the leaf spring 27. Also, instead of the leaf spring 27, wing nuts may be attached to the four screw holes 28 respectively, and the template 1 may be held on the gripping member 20 by sandwiching the template 1 with these wing nuts. Also in this case, the template 1 can be easily held only by tightening the screws. Thereafter, operator 13 turns on the power of the control device 80 and checks the operations of the first drive unit 31, the second drive unit 32, and the third drive unit 33, and checks the communication between the remote controller 50 and the control device 80, etc.

[0068] Next, operator 13 performs the positioning operation of the template 1 as follows (step S105). Operator 13 aligns the two piano wires 7 (7R, 7L) to predetermined positions by positioning (position adjustment) the template 1 using the template positioning device 10. At this time, operator 13 descends to the reference floor and operates the remote control 50 to operate the position adjustment mechanism 22 of the template positioning device 10. Also, operator 13 measures the positions of the piano wires 7R, 7L with the scale 90, and based on this measurement result, determines the drive conditions (the moving direction and moving amount of the rod) of each of the drive units 31, 32, 33. Next, operator 13 sends a command signal to the control device 80 using the remote control 50 so that each of the drive units 31, 32, 33 drives under the determined drive conditions, and adjusts the positions of the piano wires 7L, 7R. Since the piano wires 7L, 7R are pendulums with weights 9 suspended, pendulum motion occurs due to the movement of the template 1. Therefore, operator 13 removes the sway of the piano wires 7L, 7R by pressing the piano wires 7L, 7R by hand or dipping the weight 9 into a bucket filled with liquid. Next, operator 13 measures the positions of the piano wires 7L, 7R, and repeats the position confirmation and position adjustment of the piano wires 7L, 7R until the amount of displacement of the piano wires 7L, 7R from the target position (predetermined position) is within the allowable value.

[0069] In the past, when manually aligning the piano wire 7 by moving the template 1, operator 13 first measures the amount of displacement of the piano wire 7 on the reference floor. Next, operator 13 moves to the top floor and manually corrects the position of the template 1. Next, operator 13 moves back to the reference floor and measures the amount of displacement of the piano wire 7. Operator 13 repeats such operations and ends the adjustment work when the amount of displacement of the piano wire 7 is within the allowable value. For this reason, operator 13 repeats ascending and descending between the top floor and the reference floor. Therefore, the physical fatigue of operator 13 increases. Also, the time from the start to the end of the work becomes longer only by the time required for ascending and descending. Especially in high-rise floors, the influence of the time loss associated with ascending and descending appears significantly. On the one hand, when aligning the piano wire 7 using the template positioning device 10 according to the embodiment, the operator 13 can operate the remote control 50 on the reference floor to operate the template positioning device 10 on the top floor and align the piano wire 7. Therefore, the operator 13 does not need to move up and down between the top floor and the reference floor. Thus, the physical burden on the operator 13 can be reduced. Also, the time loss associated with moving up and down can be reduced.

[0070] Next, the operator 13 performs the fixing operation of the template 1 as follows (step S106). The operator 13 fixes the template 1 after positioning to the template fixture 24. At this time, the operator 13 moves to the workbench 12 on the top floor and tightens the nut engaged with the square bolt 8 described above to fix the template 1 to the template fixture 24.

[0071] Next, the operator 13 performs the removal operation of the template positioning device 10 as follows (step S107). The operator 13 releases the grip on the template 1 and removes the template positioning device 10 from the support pipe 15. At this time, the operator 13 can release the grip on the template 1 by simply pulling up the gripping member 20. Also, when using wing nuts instead of the leaf springs 27, the operator 13 can release the grip on the template 1 by loosening all the wing nuts. Also, the operator 13 loosens the fasteners 72 of each pedestal fixture 70 to release the fixed state of the pedestal fixture 70 with respect to the support pipe 15. Next, the operator 13 opens the fasteners 72 of each pedestal fixture 70 and removes the template positioning device 10 from the two support pipes 15. Thus, in this embodiment, the removal of the template positioning device 10 can be easily carried out.

[0072] As described above, according to the template positioning device 10 according to the present embodiment, after adjusting the position of the template 1 by the position adjusting mechanism 22, the position adjusting mechanism 22 can be removed from the support pipe 15 while the template 1 is supported by the support pipe 15. Therefore, the removed position adjusting mechanism 22 can be transported to another work site and used. Thus, the utilization efficiency of the template positioning device 10 can be increased, and merits can be obtained in terms of cost. Also, since it is not necessary to prepare the position adjusting mechanisms 22 for the number of work sites, the number of equipment held for positioning the template 1 can be reduced. Further, in the present embodiment, the gripping member 20 that grips the template 1 is configured to move integrally with the template 1 by the position adjusting mechanism 22. Therefore, due to the configuration of the template positioning device 10, only the gripping member 20 contacts the template 1 to position the template 1. Thus, a template positioning device 10 that can easily attach and detach the template 1 can be provided.

[0073] Also, in the present embodiment, the second drive unit 32 and the third drive unit 33 are each connected to the gripping member 20 by a connecting portion (linear motion mechanism 40, second rotary joint 52, third rotary joint 53). Thereby, the driving forces of the second drive unit 32 and the third drive unit 33 can be transmitted to the gripping member 20 via the connecting portions respectively, and the template 1 can be moved integrally with the gripping member 20.

[0074] Also, in the present embodiment, since the gripping member 20 has a gripping tool (leaf spring 27) that grips the template 1 so as to sandwich the template 1 in the short side direction of the template 1, the template 1 can be easily gripped using this gripping tool. Furthermore, by configuring the gripping tool with the leaf spring 27, the template 1 can be gripped with one touch. Therefore, the attachment and detachment of the template 1 can be performed extremely easily.

[0075] In addition, in the present embodiment, the connecting portion has a linear motion mechanism 40 that slidably supports the gripping member 20 in a predetermined direction along the longitudinal direction of the template 1 gripped by the gripping member 20. As a result, the gripping member 20 that grips the template 1 can be smoothly moved in the longitudinal direction of the template 1.

[0076] Also, in the present embodiment, the linear motion mechanism 40 is mounted on the gripping member 20. For this reason, the movement of the template 1 in the predetermined direction is guided by the linear motion mechanism 40 mounted on the gripping member 20. Therefore, the template 1 gripped by the gripping member 20 can be smoothly moved in the predetermined direction. In addition, there is no need to separately incorporate a guide member for guiding the movement of the template 1.

[0077] Further, in the present embodiment, the linear motion mechanism 40 includes a first member 41 connected to the gripping member 20, a second member 42 connected to the second drive unit 32, and a third member 43 connected to the third drive unit 33, and the first member 41, the second member 42, and the third member 43 are configured to be relatively movable in a predetermined direction. Thereby, when either one of the second drive unit 32 and the third drive unit 33 is driven, the gripping member 20 can be smoothly moved.

[0078] In addition, in the present embodiment, the template positioning device 10 further includes a first rotary joint 51 that connects the first drive unit 31 to the second member 42, a second rotary joint 52 that connects the second drive unit 32 to the second member 42, and a third rotary joint 53 that connects the third drive unit 33 to the third member 43. Thereby, even when the central axis of the rod 31c of the first drive unit 31 is not parallel to the longitudinal direction of the first member 41, or when the central axes of the rods 32c of the second drive unit 32 and 33c of the third drive unit 33 are not parallel to the longitudinal direction of the first member 41, the linear motion mechanism 40 can be smoothly operated without applying stress to the linear motion mechanism 40.

[0079] In addition, in the present embodiment, the gripping member 20 is configured to be swingable about the second rotary joint 52. Thereby, the inclination of the gripping member 20 with respect to the first direction can be adjusted by driving the third drive unit 33. Further, the position of the piano wire 7L on the side far from the second rotary joint 52 can be adjusted without significantly changing the position of the piano wire 7R on the side close to the second rotary joint 52.

[0080] In addition, in the present embodiment, the third drive unit 33 is attached to the gripping member 20. Therefore, there is no need to separately incorporate components for attaching the first drive unit 31. Thus, the configuration of the template positioning device 10 can be simplified.

[0081] In addition, in the present embodiment, by configuring at least one of the first drive unit 31, the second drive unit 32, and the third drive unit 33 with a linear actuator, the size and weight of the template positioning device 10 can be reduced.
