Description

  The present invention relates to a hook for holding a flat plate.

  When the flat plate is erected on the wall, the lower edge of the flat plate is placed in contact with the floor, the upper edge is in contact with the wall, and the flat plate is erected. In this state, the flat plate is unstable, and there is a possibility that the upright flat plate may fall down. For example, the lower side of a flat plate set against a slippery floor may slide to cause the flat plate to fall, or a person may contact the set flat plate to separate the upper side of the flat plate from the wall and fall. As a countermeasure therefor, there is known a technique using a rack for raising a flat plate so that the flat plate does not fall (for example, Patent Documents 1, 2 and 3).

  As such a flat plate, there is a cover which constitutes, for example, the outer surface of the processing apparatus. When maintaining the processing apparatus, the cover of the processing apparatus may be temporarily placed in a state of being detached and stood upright. When raising the cover, lean on the wall or the cover of the processing device that has not been removed. After maintenance is complete, attach the cover that has been raised to the processing device.

  If the operator touches the raised cover during maintenance work of the processing apparatus, the cover falls over. In order to prevent this, the cover is temporarily raised using a cover rack that can prevent the cover from falling down. However, since the cover rack is not used during normal operation of the processing apparatus, it is often stored away from the processing apparatus, and it takes extra time to locate and transport the cover rack for installation. There was a problem. Further, in the case where only the inside of the processing apparatus is checked without checking the maintenance work, the check is completed in a short time, so there is a demand for obtaining a more stable cover standing state more easily without using a cover rack. .

  The present invention has been made in view of these points, and it is an object of the present invention to provide a hook capable of preventing the falling flat plate easily and reliably.

  The present invention is a hook for preventing falling down in which a flat plate is erected, the cross section of which is U-shaped and a magnet is disposed on the outer surface, and the U-shaped opening is made downward or sideways on a magnetically attachable wall. A magnet is magnetically attached, the upper part or the side part of the flat plate standing inside the U-shape is made to enter, and the flat plate is supported so as not to fall down.

  According to the present invention, it is possible to support the upper part or the side part of the flat plate set by the hook magnetically attached to the wall, and to prevent the flat plate from falling down surely. The hooks can be disposed in a space-saving state in which they are magnetically attached to the wall when not used for holding the flat plate, so they do not get in the way and can be brought into a ready-to-use state when holding the flat plate. In addition, since the attachment of the hook is magnetic attachment, it is easy to adjust the position of the hook.

  According to the present invention, it is possible to obtain a hook capable of preventing the falling flat plate easily and reliably.

  Hereinafter, the hook according to the present embodiment and the usage thereof will be described. FIG. 1 shows the appearance of the processing apparatus, and a removable cover constituting the outer surface of the processing apparatus is an object to be held by the hook of the present embodiment. FIG. 2 and FIG. 3 show the cover removed from the processing apparatus in a state of being hooked up. FIGS. 4 and 5 show the detailed structure of the hook, and FIGS. 6 and 7 show the holding state of the cover by the hook in an enlarged manner.

  The processing apparatus 10 shown in FIG. 1 performs predetermined processing on a plate-like workpiece. The processing to be performed on the workpiece by the processing apparatus 10 is, for example, cutting, grinding, polishing, laser processing, plasma etching, edge trimming, expanded braking, etc., and the type of processing is not limited. The types of workpieces processed by the processing apparatus 10 are, for example, semiconductor device wafers, optical device wafers, package substrates, semiconductor substrates, inorganic material substrates, oxide wafers, green ceramic substrates, piezoelectric substrates, etc. There is no limitation on the type of workpiece to be processed.

  The processing apparatus 10 has a box-like external shape as a whole. The X-axis direction, the Y-axis direction, and the Z-axis direction indicated by double arrows in the drawings are the width direction, the depth direction, and the height direction of the processing apparatus 10, respectively. The hatched portions on the outer surface of the processing device 10 in FIGS. 1 to 3 indicate that coloring different from that of the other exterior portions is given.

  The processing apparatus 10 includes a loading / unloading unit 11, an operation panel 12, and operation buttons 13 on the front surface located at one end in the Y-axis direction. Loading and unloading of the workpiece into the processing apparatus 10 and unloading of the workpiece from the processing apparatus 10 are performed through the loading and unloading unit 11. The operation panel 12 is a touch panel type display unit, and an operator operating the processing apparatus 10 performs an operation using the operation panel 12 and the operation buttons 13.

  A plurality of covers 20 are attached to the side of the processing apparatus 10 facing in the X-axis direction. The cover 20 constitutes the outer surface of the processing device 10 and is removable from the main body of the processing device 10. Broadly speaking, the lower half in the Z-axis direction is covered with three covers 20A, 20B, and 20C aligned in the Y-axis direction. In addition, the upper half in the Z-axis direction is covered with five covers 20D, 20E, 20F, 20G, and 20H aligned in the Y-axis direction. The cover 20A and the cover 20B have substantially the same length in the Y-axis direction, and are longer in the Y-axis direction than the cover 20C. The covers 20D, 20E, 20F, and 20G have substantially the same length in the Y-axis direction, and are shorter in the Y-axis direction than the cover 20H. The combined length of the two covers 20D and 20E in the Y-axis direction is substantially the same as the length of the cover 20A in the Y-axis direction, and the combined length of the two covers 20F and 20G in the Y-axis direction is The length is substantially the same as the length in the Y-axis direction of the cover 20B. Further, the lengths in the Y-axis direction of the cover 20C and the cover 20H are substantially the same. In the following description, the term "cover 20" means a generic term including covers 20A to 20H.

  Although the structure of the side surface in one side in the processing apparatus 10 is only shown by FIGS. 1-3, the outer surface is comprised by the combination of a some cover also about the side surface on the other side. In addition, it is possible to configure the outer surface of the portion other than the side surface facing in the X-axis direction of the processing device 10 with a removable cover. For example, the front and back surfaces of the processing apparatus 10 can also be configured with a removable cover.

  Each cover 20 is formed of a flat plate-shaped steel plate, and is attached to the main body of the processing apparatus 10 by a predetermined attachment means. The attachment means can use any configuration such as hooking, screwing, holding by magnetic force, etc., provided that predetermined support strength and safety standards are satisfied. And the internal structure of the processing apparatus 10 can be exposed by removing the cover 20 (refer FIG. 2, FIG. 3). For example, at the time of maintenance such as inspection or repair in the processing apparatus 10, cleaning of the inside, confirmation of the inside, etc., the cover 20 is removed to enable access to the inside of the apparatus and observation. At this time, only a necessary portion of the plurality of covers 20 can be selected and removed.

  The removable cover 20 as in the present embodiment has a simple structure as compared with the open / close type external member that is connected to the main body of the processing apparatus 10 with a hinge or the like to be opened and closed, and the production efficiency is low. You can get well. There is also the advantage that it is easy to meet safety standards. On the other hand, it is necessary to pay attention to the placement and placement of the cover 20 in the removed state. That is, it is required to prevent the removed cover 20 from being placed in the form of being in the way of work or observation, or falling down from the upright state. The present embodiment uses hooks 30 to meet this requirement.

  As shown in FIGS. 4A, 4B and 5, the hook 30 has a U-shaped cross-sectional shape. More specifically, the hook 30 has a pair of parallel facing portions 31 and 32 facing each other at intervals, and a connecting portion 33 connecting the facing portion 31 and one end of the facing portion 32. The facing portion 31 is longer than the facing portion 32. And the groove part 34 enclosed by the opposing part 31, the opposing part 32, and the connection part 33 is formed. The groove 34 is open at a portion opposite to the connection portion 33.

  The hook 30 is provided with a magnet (permanent magnet) on the outer surface of the facing portion 31 (the surface on the side opposite to the side facing the groove 34). FIGS. 4A and 4B show an embodiment in which a rectangular magnet 35 is provided to cover the entire outer surface of the facing portion 31. FIG. 5 shows a mode in which the magnets 36 are embedded in the facing portion 31, and a pair of magnets 36 are provided in the longitudinal direction of the facing portion 31. The pair of magnets 36 has a disk shape, and the end face of each of the magnets 36 is exposed from a circular opening formed on the outer surface of the facing portion 31. In addition, as long as a predetermined magnetic force can be exerted on the outer surface of the facing portion 31, the magnets should be arranged in a configuration different from that shown in FIGS. 4 (A), 4 (B) and 5 Is also possible.

  The hook 30 can be magnetically attached to the wall surface of a magnetic body such as the cover 20 of the processing apparatus 10 by the magnetic force of the magnet 35 or the magnet 36. For example, FIG. 1 shows a state in which four hooks 30 are magnetically attached to the cover 20H. Then, the hook 30 in a state of being magnetically attached to the wall surface can temporarily place the cover 20 removed from the processing apparatus 10 so as not to fall down.

  FIG. 2 shows the case where the cover 20A is removed from the processing device 10 and temporarily placed. Two hooks 30 are magnetically attached to the top of the cover 20B which is not removed, and the two hooks 30 are used to stand the cover 20A. FIG. 6 is an enlarged view of this state. As shown in FIGS. 2 and 6, each of the two hooks 30 has the opening of the groove 34 facing downward, and the outer surface of the facing portion 31 (the magnet 35 shown in FIGS. 4A and 4B, or The surface on which the magnet 36 shown in FIG. 5 is disposed is magnetically attached to the outer surface of the cover 20B. The two hooks 30 are disposed at predetermined intervals in the Y-axis direction, and are disposed at substantially the same position in the Z-axis direction. The cover 20A removed from the processing apparatus 10 is erected in a state where the upper part is made to enter the groove 34 of the two hooks 30 magnetically attached to the cover 20B.

  In the state shown in FIGS. 2 and 6, the lower side of the cover 20A is brought into contact with the floor surface of the room in which the processing apparatus 10 is installed, and the cover 20A is erected. The two hooks 30 are magnetically attached to the cover 20B at a position in the Z-axis direction such that the position of the groove 34 overlaps the top of the cover 20A which is erected in the floor state. Further, the two hooks 30 are arranged at intervals shorter than the length of the cover 20A in the Y-axis direction. Furthermore, the groove width (the distance between the facing portion 31 and the facing portion 32) of the groove 34 in each hook 30 is set larger than the thickness of the cover 20A. Accordingly, the upper portion of the cover 20A can be inserted into and supported by the groove portions 34 of the two hooks 30 so as to be in a standing state (FIGS. 2 and 6).

  Since the hooks 30 are attached by magnetic force, the position adjustment with respect to the cover 20B is easy, and the optimum position for holding the cover 20A can be set without time and effort. Also, unlike a large cover rack that supports the entire cover 20A, the hooks 30 can be configured with a minimum size to prevent the cover 20A from falling down, so space efficiency is also excellent.

  In the upright state of the cover 20A shown in FIGS. 2 and 6, the hooks 30 prevent the cover 20A from falling down in the X-axis direction. More specifically, the falling of the upper portion of the cover 20A in the direction in which the upper portion of the cover 20A is away from the cover 20B (the outer direction of the processing apparatus 10) is restricted by the opposing portions 32 of the hooks 30. In particular, since the hooks 30 are provided at a plurality of positions with different positions in the Y-axis direction, a reliable fall preventing effect can be obtained. Therefore, there is no fear that the operator may touch the cover 20A removed from the processing apparatus 10 carelessly or the like, and it is possible to concentrate on the work performed with the cover 20A removed. .

  Since the cover 20A erected using the hooks 30 is positioned adjacent to the cover 20B (see FIG. 2), it is possible to temporarily set the space efficiently without interrupting the operation. Moreover, in addition to the fall prevention of the cover 20A by the opposing part 32, since the opposing part 31 functions as a spacer which gives a clearance between the cover 20A and the cover 20B, each hook 30 directly covers 20A and the cover 20B. Strong contact can prevent damage from occurring. The distance between the cover 20A and the cover 20B can be increased as the thickness of the facing portion 31 is increased.

  2 and 6 show a mode in which the lower side of the removed cover 20A is placed directly on the floor surface, but as shown in FIG. 7, in addition to the upper portion of the cover 20A, the lower side is also held by the hook 30 It is selectable. In this case, the hooks 30 supporting the lower part of the cover 20A are magnetically attached to the cover 20B with the opening of the groove 34 facing upward, contrary to the hook 30 supporting the upper part of the cover 20A. Then, the lower portion of the cover 20A is inserted into the groove portion 34, and the lower side of the cover 20A is supported by the bottom surface (connection portion 33) of the groove portion 34.

  In the upright state shown in FIG. 7, the hook 30 restricts movement of the cover 20A not only on the upper side but also on the lower side, so that the stability of the cover 20A in the temporarily placed state is further enhanced. For example, even if the floor around the processing apparatus 10 is slippery, the lower side of the cover 20A does not contact the floor, so the hook 30 arranged with the opening facing upward is not affected by the condition of the floor. Movement is restricted in the axial direction. Therefore, it is possible to prevent the cover 20A from falling down in a form in which the lower portion of the cover 20A is pulled out in the direction away from the cover 20B (the outer direction of the processing device 10). Further, when there is a possibility that the lower side of the cover 20A may be damaged due to unevenness or the like of the floor surface, the lower side of the cover 20A can be protected if it is in the upright state of FIG.

  FIG. 3 shows a state in which the second cover 20C is removed in addition to the first cover 20A, and the cover 20C is erected on the outside of the cover 20A. The hooking of the second cover 20C is performed using the hook 30 as in the case of the cover 20A described above. Specifically, the two hooks 30 are magnetically attached to the outer surface of the upper portion of the cover 20A with the opening of the groove portion 34 directed downward. Here, as shown in FIG. 3, the two hooks 30 newly magnetically attached to the cover 20A are offset from the two hooks 30 already magnetically attached to the cover 20B in the Y-axis direction, 30 interference can be prevented. Since the length of the cover 20C in the Y-axis direction is shorter than the length of the cover 20A in the Y-axis direction, the two hooks 30 for holding the cover 20C are longer than the two hooks 30 for supporting the cover 20A. Even if the distance in the Y-axis direction is narrow, stable holding can be realized (see FIG. 3). In addition to the hooks 30 supporting the upper portion of the cover 20C, the hooks 30 supporting the lower portion of the cover 20C may be magnetically attached to the cover 20A, as in the embodiment shown in FIG.

  The two hooks 30 holding the cover 20C in FIG. 3 prevent the cover 20C from falling down in the direction away from the cover 20A (the outer direction of the processing apparatus 10) by the facing portion 32. In addition, the facing portions 31 of the hooks 30 serve as spacers to prevent direct contact between the cover 20A and the cover 20C and to protect them from damage.

  As can be seen from FIG. 3, the space efficiency when temporarily placing the removed cover can be further enhanced by erecting two or more covers 20A and 20C so as to overlap in the thickness direction (X-axis direction). In the present embodiment, although the case where the number of covers to stand side by side is two sheets of the cover 20A and the cover 20C is illustrated, it is possible to stand side by side with three or more removed covers.

  The cover 20 held by the hooks 30 can be easily removed. For example, in the holding state of the cover 20A shown in FIG. 6 and FIG. 7, if the cover 20A is strongly pulled to the near side in the X axis direction, the force is also transmitted to the hook 30 via the opposing portion 32 and resists the magnetic force. The cover 20A can be removed together with the hooks 30. In addition, when the position of the cover 20A is low and it is difficult to perform the removal operation from the holding state, the cover 20A may be slightly shifted upward and then removed. In this case, the upper side of the cover 20A pushes the connecting portion 33 of the two hooks 30 upward, and the pushed hooks 30 slide upward while maintaining the magnetic attachment state with the cover 20B. Then, the cover 20A can be lowered downward, and the cover 20A can be removed together with the hooks 30.

  As another mode of removal, it is also possible to remove only the cover 20 while keeping the hooks 30 magnetically attached. For example, in the holding state of the cover 20A shown in FIGS. 6 and 7, the cover 20A is moved slightly upward (at this time, it is pushed by the upper side of the cover 20A and the upper hooks 30 are also moved upward) , Pull the lower part of the cover 20A to the near side in the X-axis direction. Then, the cover 20A performs an operation close to rotation around the upper side, inclines with respect to the X-axis direction and the Z-axis direction, and the upper portion of the cover 20A comes out of the groove 34 of each hook 30.

  When the covers 20 are pulled out from the hooks 30 while being inclined as described above, the hooks 30 may have a cross-sectional shape as shown in FIG. The hook shown in FIG. 8 has a tapered portion 37 on the inner side facing the groove portion 34 in the facing portion 32. The tapered portion 37 has an inclined surface that increases the distance from the facing portion 31 as it proceeds to the opening side of the groove 34 (that is, widens the groove width of the groove 34). By providing the tapered portion 37, insertion and removal of each cover 20 in the oblique direction with respect to the groove portion 34 can be facilitated.

  In the embodiment shown in FIGS. 6 and 7, two hooks 30 are used to hold the upper and lower portions of the cover 20A and the cover 20C, but the number of hooks used to hold one cover is arbitrarily selected. it can. For example, when there is a cover whose length in the Y-axis direction is larger than that of the cover 20A, three or more hooks 30 may be used to hold the upper and lower portions of the cover. Conversely, in the case of a cover with a small length in the Y-axis direction, it is also possible to hold with one hook 30.

  Further, as another aspect of the cover holding, as shown in FIG. 9, the hook 30 may hold the side of the cover 20. When the side of the cover 20 is held, the hook 30 is magnetically attached to the wall (not shown in FIG. 9) with the opening of the groove 34 oriented horizontally, and the side of the cover 20 is held in the groove 34 in this state. Let in. If only one hook 30 is used to hold the side of the cover 20 as shown in FIG. 9, the cover 20 is held by the hook 30 without removing the hook 30, or the cover 20 is removed from the hook 30 It is easy to

  It should be noted that, unlike the embodiment of FIG. 9, it is also possible to hold both sides of the cover 20 using a pair of hooks 30. Further, in the embodiment of FIG. 9, one side of the cover 20 is held by one hook 30, but in order to hold one side of the cover 20, a plurality of positions are changed in the Z-axis direction. It is also possible to arrange the hook 30 of

  The hook 30 in the present embodiment is for preventing falling of the cover 20 which is a flat plate, unlike the hook used for suspending the object in the vertical direction. Therefore, the hooks 30 are set in a wide shape in the surface direction of the cover to be held so that the cover 20 can be reliably held with high stability.

  The above illustrates the case where the cover 20A and the cover 20C are removed and held by the hook 30, but the other covers 20B, 20D, 20E, 20F, 20G and 20H are also removed similarly to the cover 20A and the cover 20C. In this state, the hook 30 can hold it in a stable standing state.

  In the present embodiment, in the state of FIG. 1 in which all the covers 20 are not removed, the plurality of hooks 30 are magnetically attached to the cover 20H, and the hooks 30 are removed from the cover 20H as necessary 2) and 3) is obtained. Unlike this embodiment, the hooks 30 in a state in which the cover 20 is not held may be stored at a location other than the outer surface of the processing apparatus 10.

  In the present embodiment, the thickness of the plurality of covers 20 is substantially the same, and accordingly, the plurality of hooks 30 of the same specification are aligned, but the hooks of different specifications according to the thickness and size of the cover It is also possible to use For example, when the thickness of the cover to be held is different, plural types of hooks having different groove widths of the groove 34 may be prepared, and the hooks may be selected according to the thickness of the cover. Alternatively, the groove width of the groove 34 may be variable in one hook. Specifically, a structure in which the length variable mechanism is mounted on the connection portion 33 and the distance between the facing portion 31 and the facing portion 32 is changed is possible. Furthermore, depending on conditions such as load resistance, plural types of hooks having different lengths and widths (sizes in the Z-axis direction and Y-axis direction) of the facing portion 31 and the facing portion 32 may be prepared. When a plurality of types of hooks are provided, it is preferable to be able to identify the type by color coding, marking, or the like.

  Further, in order to improve the stability of the cover 20 in the held state, an elastic material or the like such as rubber may be provided on the inner side surface of the groove 34 of the hook 30. Alternatively, the inner surface of the groove 34 of the hook 30 may have a shape other than a simple plane. For example, an elastically deformable tongue-like lip may be projected from the inner surface of the groove 34 so that the cover 20 enters the groove 34 while elastically deforming the lip. According to this configuration, since the lip portion in the elastically deformed state presses the cover 20, the width of the groove 34 of the hook 30 is not changed, and the cover having different thickness can be held.

  In the present embodiment, although the target to which the hook 30 is magnetically attached is the cover 20 of the processing apparatus 10, the hook is magnetically attached to a wall other than the cover 20 (e.g., a wall surface of a room where the processing apparatus 10 is installed) It is also good.

  Moreover, although each embodiment of this invention was described, you may combine the said embodiment and modification with the whole or partial as another embodiment of this invention.

  Furthermore, the embodiments of the present invention are not limited to the above-described embodiments and modifications, and various changes, substitutions, and modifications may be made without departing from the scope of the technical idea of the present invention. Furthermore, if technical progress of the technology or another technology derived therefrom can realize the technical concept of the present invention in another way, it may be implemented using that method. Therefore, the claims cover all the embodiments that can be included within the scope of the technical idea of the present invention.

  As described above, according to the present invention, it is possible to prevent the falling flat plate easily and reliably, and it is useful for various devices which may be temporarily placed in a state where the flat plate is placed upright.
