Description

  The present invention, for example, confirms that the direction of the operator's own operation and the direction of movement of the overhead crane device match when the object is suspended and moved on the overhead crane device in a factory or the like. The present invention relates to a moving direction display device for preventing the occurrence of an accident due to an erroneous operation and a transported object moving direction display system of an overhead crane device.

  For example, in a factory, an overhead crane apparatus A such as a floor-operated crane or a floor-operated crane (for example, a hoist crane or a club trolley crane) is installed.

  For example, a hoist type crane A shown in FIG. 2 includes a rail 12 provided along both walls in a factory, a crane garter 13 traveling on the rail 12, and a hoist 14 traversing along the crane garter 13. And a controller 1 that moves the moving body 2. A hoisting hook 17 is suspended from the hoist 14 via a hoisting mechanism. The conveyed product 3 is suspended and conveyed.

  In addition, this kind of overhead crane apparatus A has a configuration in which a controller 1 is a wired type and is provided with a pendant switch type controller 1 in which a cable 15 is suspended from a moving body 2 or a configuration using a wireless type controller 1. There is.

  In any case, when the overhead crane apparatus A is used to carry the work 3, the operator is positioned below the moving body 2 while operating the controller 1, and the moving body 2 (conveyed object 3). In many cases, the work of transporting the transported object 3 is performed while moving together with the movement of.

  In general, the operation unit of the controller 1 often displays the moving direction in the east, west, north, and south directions, and the display indicating the direction in the factory also in the factory, for example, the bottom surface of the overhead crane apparatus A or the factory East, West, North, and South are displayed on the wall surface, etc., and the operator looks at this display, confirms the moving direction of the conveyed product 3, and operates the controller 1.

  However, in the case of carrying work using the overhead crane apparatus A, the conveyed product 3 is almost located higher than the worker, and the operator's line of sight is always above, while the controller 1 is used by the worker. Is held in the hand, and is usually operated around the front of the upper body of the worker, so that the worker faces down when operating the controller 1 and immediately turns up immediately after the operation. The moving direction has to be confirmed one by one, and this confirmation work is troublesome for the operator.

  For this reason, there are some skilled workers who operate without looking at the operation unit of the controller 1 and some who neglect the confirmation work of the moving direction. If 16 is mistakenly pressed, the moving body 2 may move in a direction different from the direction intended by the worker, and an accident may occur in which the conveyed product 3 collides with an installation or worker in the factory.

  Therefore, as a countermeasure for preventing a collision accident due to an erroneous operation of the controller 1, conventionally, when the operator operates the controller 1, as described in, for example, Japanese Patent Application Laid-Open No. 2009-62156, Is reported to the worker by voice, and a method is proposed in which a moving body starts moving a few seconds later so that an erroneous operation can be dealt with early.

JP 2009-62156 A

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  When the operator operates the controller 1 that moves the moving body 2 in a desired direction in order to carry the transported object 3, the moving direction of the moving body 2 is set on the worker's walking surface 5 by the light emitted from the irradiation unit 6. A pointing direction display 7 is formed.

  Accordingly, even if the operator operates the controller 1 and does not visually recognize the moving body 2 or the transported object 3 positioned above each other, the operator can visually recognize the direction indication display 7 and simultaneously operate the transported object 3. This means that the direction in which the (moving body 2) moves can be recognized. Therefore, when the operator tries to move the moving body 2 by an erroneous operation and the actual moving direction of the moving body 2 is different, Can be recognized immediately, so that the operation can be stopped immediately to help prevent accidents caused by misoperation.

  In addition, since the present invention is a transported object movement direction display system for an overhead crane apparatus that includes the overhead crane apparatus A, if the operator erroneously operates the overhead crane apparatus A, the movement direction of the moving body 2 is determined by the operator. When the desired direction differs from the actual direction, this can be recognized immediately, so that the operation can be immediately stopped to help prevent a collision accident due to an erroneous operation.

  In addition, the description of “walking surface” in claim 1 is not limited to the floor surface or the ground on which the worker walks, but the place where the operator operates the controller 1, for example, the surface of the operation table or the direction indication. A dedicated surface for displaying the display 7 is also included.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In this embodiment, the present invention is applied to a hoist crane A.

  The description of the hoist type crane is omitted because it overlaps with the description in the background art section.

  In this embodiment, the transported object 3 mounted on a hoist crane A installed on the ceiling of a factory and suspended by a worker on a suspension hook 17 provided on a hoist 14 of the hoist crane A is placed in a desired direction. When transporting the moving body 2 by operating the controller 1 for transportation, the moving direction display device and the ceiling display a direction indication display 7 indicating the moving direction of the transported object 3 on the walking surface 5 of the worker. It is a conveyed product moving direction display system of a crane apparatus, Comprising: It comprises the base | substrate part 4 and the irradiation part 6 formed with the light emission part 8 provided in this base | substrate part 4 with two or more.

  The configuration of this embodiment will be described below.

  As shown in FIG. 1, the present embodiment is constituted by a base portion 4 and an irradiation portion 6 formed by a plurality of light emitting portions 8 provided on the base portion 4.

  Specifically, the flexible tube 10 is provided to protrude from the base portion 4, the light emitting unit 8 is provided at the tip of the flexible tube 10, and the irradiation unit 6 is provided to be adjustable.

  Further, by adopting this flexible tube 10, it is possible to easily adjust the irradiation direction of the light-emitting portion 8 by manually angling the flexible tube 10, and for example, by a mechanical adjustment mechanism by vibration Although there is a risk that the irradiation position will be shifted, the flexible tube 10 absorbs vibration generated when the moving body 2 moves and has a function of preventing the irradiation position from being shifted, and is easy to operate. Even if the deviation occurs, it can be easily adjusted.

  The structure will be described in more detail. Eight flexible tubes 10 are provided on one surface of the base portion 4, and the light emitting portion 8 is provided at each tip of the flexible tube 10 to form the irradiation unit 6.

  The irradiation unit 6 is formed by arranging the eight light emitting units 8 in four vertical and four horizontal cross shapes, and displays the reference point 9 indicating the current position of the moving body 2 by the four light emitting units 8 arranged inside. In addition, the direction indication display 7 indicating the direction in which the moving body 2 moves by the four light emitting units 8 on the outer side, specifically, the direction of east, west, south, and north is displayed.

  Further, in this embodiment, a laser is employed as the light source of the light emitting unit 8, and the red light emitted from the laser improves the visibility and can easily recognize the moving direction of the moving body 2, Since the strength and straightness are excellent, for example, display adjustment of the direction indication display 7 on the walking surface 5 after being mounted on the moving body 2 is easy.

  In addition, a lens holder 11 is provided in the light emitting unit 8, and the size of the direction indication display 7 that is irradiated from the light emitting unit 8 and displayed on the walking surface 5 of the worker is set to be easily visible to the operator, and the shape is set. It is designed to be elliptical.

  With this configuration, the irradiation unit 6 forms the reference point 9 indicating the current position of the moving body 2 with respect to the worker's walking surface 5 in a cross shape, and indicates the direction in which the transported object 3 moves. Since the direction indication display 7 is formed in an elliptical shape, and in this embodiment, the reference point 9 is always formed in a lighting state, and the direction indication display 7 is formed in a blinking state. The display 7 can be easily distinguished from each other. Therefore, the operator can recognize in which direction the conveyed product 3 moves immediately at a glance.

  The configurations of the reference point 9 and the direction indication display 7 are not limited to the present embodiment, and the number of the light emitting units 8 and the presence / absence of the use of the flexible tube 10 constitute a function capable of instructing the moving direction of the moving body 2. Any change can be made as long as possible.

  Further, for example, the light emitting unit 8 is configured to irradiate a shape different from the direction indication display 7 such as a cross shape, or the controller 1 is not operated by providing, for example, four light emitting units 8 in a cross shape. When the four light emitting units 8 irradiate the same light beam to form a cross-shaped reference point 9 on the walking surface, the light emitting unit 8 irradiating the moving direction when the operator operates the controller 1. The reference point is formed by forming the direction indication display 7 by being in a different state from the other light emitting units 8 (for example, the color changes, the shape changes, or changes from lighting to blinking). By adopting a configuration in which the light emitting unit 8 and the light emitting unit 8 that forms the direction indication display are combined, the number of the light emitting units 8 of the irradiation unit 6 can be reduced, and it can be manufactured at a lower cost.

  The display shape of the reference point 9 and the direction indication display 7 may be other shapes such as an arrow, a line, or a point, for example. Alternatively, the reference point 9 is not formed, and the operator can use the direction indication display 7 alone. It is also possible to use a display that allows the user to easily recognize the moving direction, for example, an arrow, a display that uses a blinking action, or the like.

  The light source employed in the light emitting unit 8 may be other than a laser. For example, a halogen lamp or an LED lamp may be used. By combining these to provide a difference in the color of the light, the display color that the light irradiates on the walking surface 5. The reference point 9 and the direction indication display 7 may have different colors so that the reference point 9 and the direction indication display 7 can be easily identified.

  The present embodiment configured as described above is provided in the moving body 2 or the controller 1 of the hoist type crane A in the factory. Specifically, a usage example when the present embodiment is mounted on the moving body 2 will be described below.

  As shown in FIG. 2, the hoist type crane A according to this embodiment is mounted on the hoist 14 on the lower surface or side surface of the hoist 14 provided on the crane gutter 13, and the irradiation unit 6 is directed toward the walking surface of the operator. The reference point 9 and the direction indication display 7 formed on the walking surface 5 by the laser beam irradiated from the light emitting unit 8 through the flexible tube 10 can be simultaneously viewed by the operator while operating the controller 1. It is only necessary to bend the flexible tube 10 by hand so that the display position can be obtained and to provide the light emitting portion 8 at an appropriate angle.

  Therefore, since the direction indication display 7 can be easily adjusted to a position where the operator can easily see the hoist type crane A regardless of the height of the hoist type crane A, the hoist type crane installed at various heights. It becomes the outstanding moving direction display apparatus which can respond to A, and the conveyed product moving direction display system of an overhead crane apparatus.

  Further, as described above, the present embodiment is mounted on the hoist 14, so that the reference point 9 indicating the current position of the hoist 14, that is, the position of the transported object 3, is set by the laser beam constantly irradiated from the irradiation unit 6. When the operator presses the operation button 16 of the controller 1 in order to move the conveyed product 3 in a desired direction, the reference point 9 is formed from the irradiation unit 6. The laser beam is emitted from the light emitting unit 8 different from the illuminating light emitting unit 8, and the operator forms a direction indication display 7 that indicates in which direction the conveyed product 3 moves with respect to the reference point 9. It is possible to recognize at a glance which direction the conveyed product 3 moves.

  Specifically, as shown in FIG. 3, for example, when the operator presses the operation button 16 that instructs the east of the controller 1, an elliptical shape in the east direction with respect to the reference point 9 lit in a cross shape. The direction indication display 7 is formed in a blinking state. For example, when the operator presses the operation button 16 indicating the west of the controller 1, an elliptical shape is formed in the west direction with respect to the reference point 9 lit in a cross shape. Since the direction indication display 7 is formed in a blinking state, it becomes obvious at a glance that the hoist 14 moves in the direction indicated by the direction indication display 7 from the reference point 9, that is, the current position of the hoist 14.

  Therefore, even if the operator accidentally presses the operation button 16 that is different from the operation button 16 intended by the operator, the operator immediately recognizes that the transported object 3 moves in a direction different from the intended direction. Since it is possible to recognize that it has been mistakenly operated and to immediately stop the operation, it is useful for preventing the occurrence of an accident in which the transported object 3 suspended on the hoist 14 moves toward the installation object or the worker in the factory and collides with it. An excellent moving direction display device and an object moving direction display system for an overhead crane device are provided.

  In FIG. 2 for explaining the present embodiment, the controller 1 is of a wired type, but the operation and effect are the same for the wireless type controller 1 as well.

  Furthermore, in the case of the wireless type controller 1, for example, the mobile body 2 can be operated by remote control without running in parallel with the mobile body 2, and in such a case, the floor of the place where the operator remotely operates. The present embodiment may be provided above an operator such as a ceiling so that the reference point 9 indicating the moving direction of the moving body 2 and the direction indication display 7 are formed on the surface or the ground.

  In addition, in this embodiment, the timing for forming the direction indication display 7 on the walking surface 5 when the controller 1 is operated is set to be displayed simultaneously with the movement of the moving body 2. If it is set so that the moving body 2 starts moving several seconds after the indication display 7 is formed, preferably 3 to 5 seconds, the time for recognizing the moving direction of the moving body 2 and determining the presence or absence of an erroneous operation can be spared. Therefore, it can be used to more reliably prevent the occurrence of a collision accident due to an erroneous operation.

  In the operation of the controller 1, for example, when the operation button 16 is pressed halfway, the moving body 2 does not move and only the direction indication display 7 is formed (the reference point 9 is always lit). If the moving body 2 is configured to move when the operation button 16 is fully pressed, the moving body 2 can be easily moved after the operator always recognizes the moving direction. Can help to prevent.

  In addition, a present Example exhibits the same effect also in overhead crane apparatuses other than the hoist type crane A, for example, a club trolley type crane, a messenger system, a fixed position system floor-operated crane, etc.

  The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate.
