It becomes like this.

Hereinafter, the present invention will be described with reference to the drawings.
The present invention is, for example, a holding device for a transported object for a wagon used in a clean room (or any other place), which is appropriately mounted on a wagon W. For example, a storage case storing a plurality of semiconductor wafers or other semiconductor components or semiconductor products or chemicals, precision equipment, etc.) can be easily placed and stably held. It can be transported as it is and can be easily released from its holding state.
Specifically, the base frame A is mounted on the wagon W via a vibration isolator G, and is mounted on the base frame A so as to be swingable in the vertical direction via the left and right lower shaft pins F1. The left and right lower swing frames B, the left and right mast plates D that are erected and fixed to the base frame A, and the left and right upper shaft pins F3 that are respectively disposed above the left and right mast plates D are vertically moved. Left and right upper swing frames C mounted so as to be swingable in the direction, and base ends of left and right lower swing frames B and base ends of left and right upper swing frames C, respectively. A connecting rod E is provided for connecting the swinging motions of the left and right lower swing frames B and the left and right upper swing frames C respectively.
Then, the transported object H is placed so as to straddle the left and right receiving plates 6 provided at the front ends of the left and right lower swing frames B, and the load of the transported object H causes the left and right lower swing frames B to move. When the left and right receiving plates 6 are swung downward, the left and right presser plates 11 provided at the front ends of the left and right upper swing frames C swing greatly downward, and the object to be transported H can be held from above. By configuring as described above, the above-described problems can be achieved.

The base frame A is formed in a substantially rectangular frame shape by an appropriate metal material having conductivity, for example. And it is formed in the dimension slightly smaller than the upper frame member of the wagon W. That is, the base frame A does not protrude laterally from the upper frame member of the wagon W, and the base frame A is formed so as not to be subjected to impacts or vibrations by directly contacting the side wall or the like.
Further, the base frame A is provided with a horizontal member 1 facing the horizontal member provided on the upper frame member of the wagon W on the left and right sides. The horizontal member 1 and the upper frame member are horizontally mounted. A plurality of anti-vibration bodies G are interposed between the two members, and the vibration of the wagon W is difficult to be transmitted to the base frame A.
Further, a stopper 2 such as a rectangular plate bent in a substantially L shape is fixed inside each frame member in the longitudinal direction of the base frame A. The stopper 2 is fixed to the tip of the lower swing frame B. The portion is formed so as to support the left and right lower swing frames B by contacting when the portion swings downward to a predetermined position (position where the conveyed object H is held) (see FIG. 4).

The lower oscillating frame B has, for example, a pair of lower oscillating arms 5 that have a substantially rectangular band plate shape and are spaced apart from each other by a predetermined distance, and tip portions of the pair of lower oscillating arms 5. Are formed in a substantially rectangular frame shape by a receiving plate 6 arranged so as to connect the two and a horizontal connecting member 7 arranged so as to connect the base end portions of the pair of lower swing arms 5. In addition, these are formed of an appropriate metal material having conductivity.
The lower swing frame B is formed so that the center portion of each of the pair of lower swing arms 5 is penetrated by the lower shaft pin F1 mounted at a predetermined position of the base frame A. It is configured to be swingable in the vertical direction with F1 as a fulcrum.
Further, a substantially elongated strip-like locking protrusion 8 is fixed (or integrally provided) to the horizontal connecting member 7, and the locking protrusion 8 is connected to the tip of the lower swing frame B. When the portion swings upward to a predetermined position (the holding state of the transported object H is released and the tip portion of the lower swing frame B is at the highest position), the base frame A is placed on the upper surface of the frame material in the short direction. The left and right lower swing frames B are formed so as to be in contact with each other (see FIG. 2). Note that a cushion material is appropriately fixed to the lower surface of the locking projection piece 8 (or the upper surface of the frame material in the short direction of the base frame A), and the locking protrusion piece 8 is a frame material in the short direction of the base frame A. You may form so that it may become a shock absorbing material, when abutting on an upper surface.
In addition, a lower connecting shaft F <b> 2 that passes through these portions is attached to the proximal end portions of the pair of lower swing arms 5.

  The receiving plate 6 only needs to be formed so as to be able to stably receive the bottom of the object to be transported H, and, for example, a silicon buffer sheet is bonded to the top surface of the receiving plate 6 to be transported. The adhesion to the object H is improved, the anti-slip effect can be exhibited, the damage to the conveyed object H and the receiving plate 6 can be prevented, and the conveyed object H is more stable without rattling. It can be held and is configured to be useful for protecting the conveyed object H.

The upper swing frame C has, for example, a pair of upper swing arms 10 that have a substantially frontal deformed L-shaped band plate and are spaced apart by a predetermined distance, and the tips of the pair of upper swing arms 10. The presser plate 11 is arranged so as to connect the portions, and is formed in a plane groove shape. In addition, these are formed of an appropriate metal material having conductivity.
Further, the upper swing frame C is formed so that the center portion of each of the pair of upper swing arms 10 is penetrated by the upper shaft pin F3 mounted so as to penetrate the upper portions of the pair of mast plates D. The upper shaft pin F3 is used as a fulcrum so that it can swing up and down.
In addition, an upper connecting shaft F4 penetrating through the upper end of the pair of upper oscillating arms 10 is attached.

  The presser plate 11 may be formed so as to be able to stably hold the upper part of the object to be transported H. Moreover, for example, a buffer sheet made of silicon is bonded to the lower surface of the presser plate 11 to be transported. The adhesion to the object H is improved, the anti-slip effect can be exhibited, the damage to the conveyed object H and the presser plate 11 can be prevented, and the conveyed object H can be more stably without rattling. It can be held and is configured to be useful for protecting the conveyed object H.

  The mast plate D is formed of, for example, an appropriate metal plate material having conductivity, and is fixed to the left and right ends of the frame material in the longitudinal direction of the base frame A, respectively. In addition, upper shaft pins F3 are horizontally arranged so as to connect the upper portions of the pair of mast plates D on the left and right. That is, the mast plate D only needs to be formed so as to stably support the upper swing frame C and not to interfere with the holding operation of the conveyed object H.

  The connection rod E is formed of, for example, an appropriate metal material having a substantially elongated strip shape having conductivity, and an upper end portion thereof is penetrated by the upper connection shaft F4, and a lower end portion thereof is penetrated by the lower connection shaft F2. The base end portion of the swing frame B and the base end portion of the upper swing frame C are provided so as to be connected. That is, the lower swing frame B and the upper swing frame C are connected to each other, and the object H is placed on the receiving plate 6 of the lower swing frame B, and the lower swing frame B is swung downward by the load. When this is done, the upper swing frame C swings downward greatly by the connecting rod E so that the conveyed object H can be pressed from above by the presser plate 11. The swing amount of the upper swing frame C with respect to the swing amount of the lower swing frame B is adjusted by the ratio of the distance between the lower shaft pin F1 and the lower connection shaft F2 and the distance between the upper shaft pin F3 and the upper connection shaft F4. By doing so, it becomes possible to set freely.

  The vibration isolator G may be formed of, for example, a suitable rubber material having conductivity and formed so that the vibration of the wagon W is not easily transmitted to the base frame A (holding device).

The wagon W is preferably configured to be able to move smoothly in a clean room or the like and to be able to flow the generated static electricity to the floor of a conductive clean room.
In addition, the base frame A, the lower swing frame B, the upper swing frame C, the mast plate D, the connection rod E, the lower shaft pin F1, the lower connection shaft F2, the upper shaft pin F3, the upper connection shaft F4, and the vibration isolation. The body G and the like are also made of a conductive material, and static electricity generated in the holding device itself can flow through the wagon W to the floor of the clean room. That is, it is only necessary to take into consideration that static electricity generated in the holding device itself does not adversely affect the conveyed object H.

  The transported object H includes, for example, a synthetic resin storage case storing a plurality of semiconductor wafers or other semiconductor components or semiconductor products, a storage case storing a plurality of chemicals, and a precision instrument such as an inspection machine. The shape and interval of the receiving plate 6 and the shape and interval of the presser plate 11 can be set and changed in accordance with these specific dimensions and shapes.
