Description

  The present invention relates to an industrial magazine rack that stores and holds plate-like members such as a printed wiring board, a liquid crystal substrate, a disk substrate, and a semiconductor wafer.

  Industrial magazine racks are used to transport plate-like members, which are substrate materials, in product production lines. For example, in a production line for manufacturing a mounting board on which a required electronic circuit component is mounted on a printed wiring board, an industrial magazine rack is placed on a transfer base that connects the manufacturing process of the printed wiring board and the mounting process of the electronic circuit component. Install. Then, after sequentially storing a plurality of printed wiring boards manufactured in the printed wiring board manufacturing process in an empty industrial magazine rack, the industrial magazine rack is transferred to an electronic circuit component mounting process. In the electronic circuit component mounting process, the printed circuit boards stored in the industrial magazine rack are taken out one by one to mount the electronic circuit components, and the manufactured mounting substrate is stored again in the industrial magazine rack. . The industrial magazine rack in which the mounting substrate is stored is removed from the transfer base by an operator and transferred to a required storage location.

  As described above, the industrial magazine rack may be removed from the transport base by an operator and transferred to another location. In this case, it is practically difficult to keep the industrial magazine rack horizontal. The stored plate-like member tends to protrude from the industrial magazine rack, or in the worst case, it drops off from the industrial magazine rack. Therefore, the operator must carefully transport the industrial magazine rack. When the plate member protrudes from the industrial magazine rack, the protruding plate member is placed in a predetermined position in the industrial magazine rack. Since work to return to is required, workability is reduced. Further, when the stored plate-like member is dropped from the industrial magazine rack, the plate-like member becomes a defective product, so that the yield of non-defective products decreases.

  In order to prevent the occurrence of such inconvenience, various industrial magazine racks having a stopper mechanism at or near the opening have been proposed (see, for example, the summary of Patent Document 1). The wafer ring rack described in Patent Document 1 includes a stopper support frame formed on the inner wall surface near the insertion opening of the side plate, a stopper member fitted in the support frame so as to be movable in the vertical direction, and a stopper. It consists of a groove and protrusion with the same pitch as the side plate provided on the member wall surface, and a stopper stopping mechanism that holds the stopper member on the support frame.When the rack body is lifted from the plane, the stopper body moves downward, The stopper member lower end protrudes from the bottom surface of the side plate while the stopper stopping mechanism operates, and the groove position of the side plate and the groove position of the stopper member are different. According to this structure, when the wafer ring is transferred, the stopper mechanism automatically operates, and when the rack body is placed on a flat surface, the stopper mechanism is automatically released. In comparison, the workability can be improved and the occurrence of inconvenience due to forgetting to open and close the stopper mechanism can be avoided.

Utility Model Registration No. 3014870

  However, the wafer ring rack described in Patent Document 1 allows a stopper member having grooves and protrusions having the same pitch as the side plate to be moved up and down in a stopper support frame formed on the inner wall surface near the insertion opening of the side plate. When the rack body is stored and lifted from the plane, the groove formed on the side plate is closed by the protrusion formed on the stopper member, so that the plate-like member is prevented from protruding or falling off from the rack body. For example, there is a problem that it is not suitable for storing a plate-like member having a rectangular planar shape such as a printed wiring board. That is, in the wafer ring rack described in Patent Document 1, a large stopper member having grooves and protrusions must be disposed opposite to the end surface of the plate-like member. The wafer ring rack becomes larger and heavier than the full length. The wafer ring rack described in Patent Document 1 stores the stopper member in a stopper support frame formed on the inner wall surface near the insertion opening of the side plate, and the left and right end portions of the plate member stored in the rack body. Therefore, when a printed wiring board or the like having a notch at the corner is stored, the plate-like member moves in the rack until the stopper member hits the bottom of the notch, Protrusion of the plate-like member from the rack body cannot be prevented.

  The present invention has been made to solve such problems of the prior art, and the object thereof is to reduce the size and weight of the plate member and prevent the plate-like member from protruding and falling off from the rack body, and the planar shape is different. An object of the present invention is to provide an industrial magazine rack capable of storing various plate-like members.

  In order to solve such a technical problem, the present invention is formed on a rack body including two side plates arranged opposite to each other with a required interval, and inner surfaces of the two side plates. A plurality of guide ribs formed, an insertion space for the plate-like member defined by the guide ribs, and when opened, the plate-like member is inserted from the outside into the insertion space and the plate from the insertion space to the outside A stopper member that enables removal of the plate-like member and disables insertion of the plate-like member from the outside into the insertion space and removal of the plate-like member from the insertion space to the outside when closed. In the industrial magazine rack, the stopper member having a plate shape in cross section and a front shape in an L shape is used, and the bent portion of the stopper member is rotatably connected to the end of the rack body. When the rack body is lifted, the stopper member rotates by its own weight, the vertical piece of the stopper member closes the opening of the rack body, and when the rack body is placed on a plane, The horizontal piece of the stopper member is pushed by the plane and rotates in the reverse direction, and the vertical piece of the stopper member is retracted to the outside from the opening of the rack body.

  If the stopper member has a plate-like cross-sectional shape, the setting space of the stopper member relative to the rack body can be reduced, so that the depth size of the rack body can be made slightly larger than the depth size of the plate member, An increase in the size of the rack body can be prevented. When the front surface of the stopper member is formed in an L shape and the bent portion of the stopper member is pivotally connected to the end of the rack body, the stopper member becomes free by lifting the rack body. Since the vertical piece of the stopper member automatically rotates in the direction of closing the opening of the rack member according to the weight of the horizontal piece of the stopper member, the stopper member can be opened and closed automatically. Further, according to this configuration, when the rack body is lifted, the vertical piece of the stopper member rotates around the connecting portion provided in the bent portion and protrudes to the middle of the opening of the rack member. The plate-like member having a notch can also be stopped at the end of the rack body, and the projection of the plate-like member from the rack body can be reliably prevented.

  In the industrial magazine rack having the above-described configuration, at least one of the rack main body and the vertical piece of the stopper member and the rack main body and the horizontal piece of the stopper member may be provided. Are slidably connected to each other.

  If the rack body and the vertical piece of the stopper member are slidably connected, the vertical piece of the stopper member can be supported by a double-supported structure, so that the strength of the stopper member can be increased, and the plate stored in the rack body The deformation of the vertical piece of the stopper member can also be prevented when receiving the pressing force of the member. The same applies to the case where the rack body and the lateral piece of the stopper member are slidably connected.

  According to the present invention, in the industrial magazine rack configured as described above, a weight is attached to a lateral piece of the stopper member.

  If a weight is attached to the lateral piece of the stopper member, the rotational force of the stopper member when the rack body is lifted can be increased, so that the opening operation of the stopper member can be made smoother.

  According to the present invention, in the industrial magazine rack having the above-described configuration, a reinforcing member is attached to a vertical piece of the stopper member.

  If a reinforcing member is attached to the vertical piece of the stopper member, the rigidity of the stopper member can be increased, so that deformation of the vertical piece of the stopper member is suppressed when the pressing force of the plate-like member stored in the rack body is received. can do.

  According to the present invention, in the industrial magazine rack configured as described above, the side plate is formed with a recess or a through-hole for an operator to hold the rack body.

  When the holding recesses or through-holes are formed in the side plate constituting the rack body, the weight of the side plate and hence the industrial magazine rack can be reduced, so that the burden on the operator when handling the industrial magazine rack can be reduced.

  According to the present invention, a stopper member having a plate shape in cross section and a front shape formed in an L shape is used, and a bent portion of the stopper member is rotatably connected to an end portion of the rack body. When the rack member is lifted, the stopper member rotates by its own weight, the vertical piece of the stopper member closes the opening of the rack body, and when the rack body is placed on a flat surface, the horizontal piece of the stopper member is pushed to the flat surface. Since the vertical piece of the stopper member is retracted to the outside from the opening of the rack body, the rack body is downsized, the opening and closing operation of the stopper member is automated, and the corner portion is It is possible to prevent the notched plate member from protruding from the rack body.
