Description

The present invention relates to an article moving device for moving a remote monitoring camera to an arbitrary position, which is used for maintenance, inspection, maintenance, etc. of various buildings such as bridges and water gates, and equipment incidental thereto.

Various structures such as bridges and water gates and their associated equipment require regular maintenance, inspection, and maintenance work. Hereinafter, buildings and incidental equipment that are subject to maintenance, inspection, and maintenance will be simply referred to as "equipment subject to maintenance." Facilities subject to maintenance require maintenance, inspection, maintenance work, and monitoring of operating status even in the event of a disaster such as an earthquake, heavy rain, or fire. Work on such equipment to be maintained often requires a wealth of knowledge and experience, so it has been necessary for skilled workers to travel to the site. On the other hand, due to the recent labor shortage, the number of skilled workers is decreasing, and it is expected that it will be difficult to properly operate equipment subject to maintenance in the future.

Therefore, network cameras are installed at equipment to be maintained in order to perform maintenance and inspection remotely, and to allow skilled workers to provide timely guidance to on-site workers during maintenance (for example, (See Patent Document 1.) The network camera is configured to be able to distribute video to user terminals via the Internet. Depending on the model of the network camera, it is also possible to control the direction, zoom, etc. of the camera from a user terminal.

However, although it is possible to control the direction of the network camera, it is not possible to move the position of the camera itself. Therefore, depending on the arrangement of objects for maintenance or the like, it is difficult to image all the objects with one network camera. Therefore, it is conceivable to provide a mobile device that moves the network camera and to control this mobile device from a user terminal. In this case, control signals for controlling the mobile device are sent from the user terminal to the mobile device in the same way as control signals for the network camera itself.

Further, the moving device includes a pair of first guide rails extending parallel to each other in the horizontal direction, a second guide rail extending in a direction perpendicular to each first guide rail, and a second guide rail that moves to the second guide rail. a movable unit movably supported, a first drive mechanism for moving the movable unit along a second guide rail, and a second drive for moving the second guide rail along each first guide rail. A mechanism for moving the moving unit in the X direction along the second guide rail and moving the second guide rail in the Y direction along each first guide rail, thereby moving the moving unit in the X direction. A device that can be moved to an arbitrary position in the direction and the Y direction is known (for example, see Patent Document 2).

However, in conventional moving devices, multiple drive mechanisms are provided for each guide rail, and each is composed of mechanical parts such as motors, gears, and ball screws, which complicates the overall structure and wiring of the device. As the length of the guide rail increases, the drive mechanism also increases in length, resulting in an increase in manufacturing costs.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an article moving device that can simplify the structure of the entire device.

In order to achieve the above object, the present invention includes a pair of first guide members extending parallel to each other, a second guide member extending in a direction perpendicular to each first guide member, and a second guide member supported by the second guide members. In the article moving device, the moving unit supporting the object to be moved is moved along each guide member, wherein the second guide member rotates around an axis to move the moving unit supporting the object to be moved along each of the first guide members. The moving unit is configured to move along a guide member, and the moving unit includes a first drive mechanism that moves the moving unit along the second guide member, and a second drive mechanism that moves the moving unit along the second guide member without rotating the moving unit. A second drive mechanism is provided for rotating the member about the axis relative to the moving unit to move the moving unit along with the second guide member along each first guide member.

This allows the first and second drive mechanisms to be integrated into the movement unit, compared to conventional systems in which drive mechanisms for moving in the X and Y directions are provided separately for each guide rail. The mechanism allows the mobile unit to be moved. In addition, if the movement range of the mobile unit differs depending on the installation location, it is only necessary to form each first guide member and second guide member to a length that corresponds to the movement range of the mobile unit, so it is necessary to design the entire device. There is no need to make changes, and there is no need to prepare devices with multiple types of specifications depending on the range of movement.

According to the present invention, since the moving unit can be moved by the first and second drive mechanisms that are integrally provided in the moving unit, the structure of the entire device can be simplified. In addition, even if the movement range of the mobile unit differs depending on the installation location, there is no need to change the design of the entire device, and there is no need to prepare devices with multiple specifications depending on the movement range, making it a highly versatile mobile device. It has the advantage that it can be constructed at low cost.

The support member 61 is made up of a plurality of pipe-shaped rod members 61 having different diameters, and the rod members 61 are arranged in order from the top to the bottom in descending order of diameter.

The motor 73 is attached to the inner surface of the other side plate 31 of the moving unit 30, and its rotating shaft 73a is connected to the reel 72 via a torque splitter 73b.

Although not shown, a power cable for driving each of the motors 42, 53, and 73 is connected to the moving unit 30. In this case, since the first drive mechanism 40 rotates with respect to the moving unit 30, the power cable cannot be directly connected, but for example, each side plate 11 of the moving unit 30 and each rotation support part of the first drive mechanism 40 By providing electrodes that are slidably in contact with each other between the moving unit 30 and the moving unit 44, power can be supplied from the moving unit 30 side to the first driving mechanism 40 side while rotating the first driving mechanism 40. Further, by switching the polarity of the power supply connected to each motor 42, 53, 73, each motor 42, 53, 73 can be switched between forward rotation and reverse rotation.

In the article moving device configured as described above, the first drive mechanism 40, the second drive mechanism 50, and the third drive mechanism 70 are operated as follows to move the camera 1 in the X direction and the Y direction. It can be moved to any position in the direction and Z direction.

First, when moving the camera 1 in the X direction, the first drive mechanism 40 is activated. That is, when the motor 42 of the first drive mechanism 40 is rotated in either direction, the drive roller 41 rotates while contacting the second guide member 20 as shown in FIG. 6, and the moving unit 30 rotates in the second direction. It moves along the guide member 20 in the X direction. At this time, the moving unit 30 moves while being supported by the second guide member 20 via each guide roller 45.

Next, when moving the camera 1 in the Y direction, the second drive mechanism 50 is activated. That is, when the motor 53 of the second drive mechanism 50 is rotated in either direction, the first drive mechanism 40 rotates relative to the moving unit 30 as shown in FIG. At this time, since each guide roller 45 of the first drive mechanism 40 is locked in each recess 20a of the second guide member 20 in the circumferential direction of the second guide member 20, the second guide member 20 It rotates together with the first drive mechanism 40 while being engaged with each guide roller 45 . As a result, as shown in FIGS. 9 and 10, the traveling rollers 22 of each traveling unit 21 rotate together with the second guide member 20, and the traveling rollers 22 rotate while contacting the first guide member 10. , the moving unit 30 moves along the first guide member 10 together with the second guide member 20 in the Y direction.

In addition, since the camera 1 is suspended below the moving unit 30, its center of gravity is below the rotation center of the first drive mechanism 40 (the center of the second guide member 20). When the first drive mechanism 40 rotates relative to the moving unit 30, the moving unit 30 does not rotate together with the first drive mechanism 40.

Moreover, when moving the camera 1 in the Z direction, the third drive mechanism 70 is operated. That is, when the motor 73 of the third drive mechanism 70 is rotated in one direction, the reel 72 is rotated in one direction, and the wire 71 is unwound from the reel 72. As a result, as shown in FIG. 16, the support member 60 extends downward due to the weight of the camera 1 in accordance with the amount of unwinding of the wire 71, and the camera 1 moves in the Z direction (downward). Further, when the motor 73 of the third drive mechanism 70 is rotated in the other direction, the reel 72 is rotated in the other direction, and the wire 71 is wound on the reel 72. As a result, the support member 60 contracts upward, and the camera 1 moves in the Z direction (upward).

Although not shown, a control device that controls the operation of each of the drive mechanisms 40, 50, and 70 is connected to a remote terminal via a wireless communication terminal that is common to or separate from the camera 1, and is connected to a remote terminal. Each of the drive mechanisms 40, 50, and 70 is operated by operating the terminal on the ground.

As described above, according to the article moving device of the present embodiment, a pair of first guide members 10 extending parallel to each other, a second guide member 20 extending in a direction orthogonal to each first guide member 10, a moving unit 30 supported by a second guide member 20, the second guide member 20 is configured to move along each first guide member 10 by rotating around an axis, and the moving unit 30 includes a first drive mechanism 40 that moves the moving unit 30 along the second guide member 20, and a first drive mechanism 40 that moves the second guide member 20 around the axis relative to the moving unit 30 without rotating the moving unit 30. Since the second drive mechanism 50 is provided to rotate the moving unit 30 along with the second guide member 20 and move it along each of the first guide members 10, it is possible to move the moving unit 30 along the respective first guide members 10 in the X direction and the Y direction as in the conventional case. Compared to a case where drive mechanisms for movement are provided separately for each guide rail, the first and second drive mechanisms 40 and 50 that are integrally provided in the movement unit 30 move the movement unit 30 in the X direction and It can be moved in any direction in the Y direction, and the structure of the entire device can be simplified.

Furthermore, if the moving range of the moving unit 30 differs depending on the installation location, it is only necessary to form each of the first guide member 10 and the second guide member 20 to a length that corresponds to the moving range of the moving unit 30. There is no need to change the design of the entire device, and there is no need to prepare devices with multiple types of specifications depending on the range of movement. This has the advantage that a highly versatile mobile device can be constructed at low cost.

The first drive mechanism 40 also includes a drive roller 41 that contacts the second guide member 20 and a motor 42 that rotates the drive roller 41. The rotation of the drive roller 41 moves the moving unit 30 into the second guide. Since it is configured to move along the member 20, the moving unit 30 can be moved smoothly with respect to the second guide member 20, and the second guide member 20 does not require a conventional ball screw. There is no need to use a complicated configuration, and the second guide member 20 can be simplified and reduced in cost. In this case, the anti-slip member 41c provided on the outer peripheral surface of the drive roller 41 can reliably transmit power without causing the drive roller 41 to idle, and the pair of anti-slip members 41c are spaced apart from each other in the width direction. Therefore, the anti-slip member 41c can be reliably brought into contact with the outer peripheral surface of the curved second guide member 20.

Further, the first drive mechanism 40 is engaged with the second guide member 20 so as to rotate together with the second guide member 20, and the second drive mechanism 50 rotates the first drive mechanism 40. Since it is equipped with a motor 53 and is configured to move the moving unit 30 along each first guide member 10 by rotating the first drive mechanism 40 and the second guide member 20 by the motor 53, The second guide member 20 itself can be rotated and moved along each first guide member 10 by one motor 53. Thereby, there is no need to provide any drive mechanism for moving the second guide member 20 on the side of each first guide member 10, and the structure can be further simplified.

Further, since the second guide member 20 is configured to rotate while bringing the running rollers 22 provided at both ends into contact with each first guide member 10, the second guide member 20 is In addition to being able to move smoothly relative to the first guide member 10, there is no need to use a complicated configuration using a conventional ball screw for each first guide member 10, and each first guide member 10 simplification and cost reduction.

In this case, the anti-slip member 22a provided on the outer peripheral surface of the running roller 22 allows power to be reliably transmitted without causing the running roller 22 to idle, and the pair of anti-slip members 22a are spaced apart from each other in the width direction. Since the anti-slip member 22a is disposed in a circular manner, the anti-slip member 22a can be reliably brought into contact with the outer circumferential surface of the first guide member 10 having a curved surface.

Further, since the second guide member 20 and the running roller 22 are engaged with each other so as to be movable in the axial direction of the second guide member 20, even if the respective first guide members 10 are not exactly parallel to each other, While the traveling roller 22 is traveling, it moves in the axial direction of the second guide member 20 in accordance with the change in the interval between the respective first guide members 10, thereby absorbing the error in the interval between the respective first guide members 10. can. Thereby, each first guide member 10 is not required to have strict parallelism, so installation on site can be easily performed. In this case, since the stopper 20b is provided at the end of the second guide member 20, the second guide member 20 will not come off from the traveling unit 21 in the axial direction.

Furthermore, traveling units 21 are provided at both ends of the second guide member, through which the first guide member 10 is slidably inserted in the axial direction and the second guide member 20 is rotatably inserted. Therefore, each first guide member 10 and second guide member 20 can be reliably engaged by the traveling unit 21, and the second guide member 20 can be moved from each first guide member 10 in the vertical direction. It can be moved stably at all times without falling off.

Further, the running unit 20 includes a first support member 23 that supports the first guide member 10, a second support member 24 that supports the second guide member 20, and a running roller 22 that supports the second guide member 20. 20, the contact pressure between the traveling roller 22 and the second guide member 20 can be increased. Even if the relative running positions of the respective running rollers 22 deviate, the positional deviation can be easily absorbed by allowing one of the running rollers 22 to idle, and stable running is always possible.

Furthermore, the moving unit 30 includes a support member 60 that supports the camera 1 so as to be movable in a direction (Z direction) perpendicular to the axial direction of the first and second guide members 10 and 20, and a support member 60 supported by the support member 60. Since a third drive mechanism 70 is provided that moves the camera 1 in a direction perpendicular to the axial directions of the first and second guide members 10 and 20, the camera 1 can be moved not only in the X and Y directions but also in the Z direction. It can also be moved in any direction.

In this case, since the support member 60 is formed to be expandable and contractible in a direction perpendicular to the axial direction of the first and second guide members 10 and 20, the support member 60 can be expanded and contracted according to the movement position of the camera 1. This has the advantage that the support member 60 does not protrude unnecessarily from the moving unit 30.

Further, the third drive mechanism 70 includes a wire 71 connected to the support member 60, a reel 72 for winding and unwinding the wire 71, and a motor 73 for rotating the reel 72. 72 to wind up and unwind the wire 71, the support member 60 is expanded and contracted, and the camera 1 is moved in a direction perpendicular to the first and second guide members 10 and 20. Therefore, due to the flexibility of the wire 71 that connects the reel 72 and the support member 60, the reel 72 and the motor 73 can be provided at any position without being restricted by the position of the support member 60. Thereby, the reel 72 and motor 73 of the third drive mechanism 70 can be arranged in the moving unit 30 so as to be symmetrical with the second gear 52 and motor 53 of the second drive mechanism 50, and the moving unit 30 can be configured in a well-balanced manner.

Furthermore, since the second guide member 20 rotates relative to the moving unit 30 without rotating the moving unit 30, the moving unit 30 is always rotated regardless of the rotation of the second guide member 20. It can be held in a vertical position by its own weight. Thereby, even if each first guide member 20 has a slope, the moving unit 30 can be moved while being held in a vertical position, and there is an advantage that it can be used even in a sloped installation location.

In the above embodiment, a circular pipe-shaped member having a recess 20a on the outer peripheral surface is used as the second guide member 20, but a cross-sectional shape that can prevent rotation in the circumferential direction, such as a square pipe, etc. It is also possible to use a guide member.

Further, in the above embodiment, an article moving device is shown in which the object to be moved is a camera 1 for remote monitoring that is installed in a mechanical equipment room of a water gate and used for maintenance, inspection, maintenance, etc. of mechanical equipment such as a gate opening/closing device. However, the present invention is not limited to such water gate equipment, and can be used in various other applications, such as cranes that move products and equipment within factories, and game machines that lift prizes. It can also be used for moving objects.

FIGS. 17 and 18 show another embodiment of the present invention, in which the structure of the engaging portion between the first guide member 10 and the second guide member 20 is different from the above embodiment, and other parts Since this is the same as the embodiment described above, illustration and description thereof will be omitted.

In this embodiment, instead of the running unit 21 of the previous embodiment, a recess 10a extending in the axial direction is provided at the upper end side of the first guide member 10, and a running roller 26 provided at the end of the second guide member 20 is provided. is engaged with the recess 10a of the first guide member 10 from above.

As a result, the second guide member 20 rotates while causing the traveling roller 26 to engage with the recess 10a of the first guide member 10. In this case, since the second guide member 20 can be attached to and detached from the first guide member 10 from above, assembly work at the installation site can be easily performed.

Furthermore, since the recess 10a is provided at the upper end of the first guide member 10, by attaching the arc-shaped support member 13 whose upper end is cut out to the first guide member 10 from below, the recess 10a can be attached to the recess 10a. The first guide member 10 can be supported by the support member 13 without interference from the support member 13. As a result, even when the first guide member 10 has a large length dimension, by supporting at least one intermediate position in the longitudinal direction of the first guide member 10 with the support member 13, the first guide member 10 can be Deflection of the member 10 can be suppressed.

The support member 13 is attached to the upper end of the support column 13a, has an inner diameter equivalent to the outer diameter of the first guide member 10, and is formed in an arcuate shape that is slightly longer in the circumferential direction than the half circumference. In this case, by forming the support member 13 from an elastically deformable synthetic resin or the like, it can be attached to the first guide member 10 while forcibly expanding in the radial direction. Furthermore, when the guide member 10 is made of a non-elastic member such as metal, it can be attached by inserting the first guide member 10 inside the support member 13 from the end.
