Description

  The present invention relates to a magazine rack that holds stored items such as carriers and printed circuit boards.

  In general, printed circuit boards are assembled by using a plurality of assembly machines and transporting a magazine rack storing printed circuit boards between the respective assembly machines. By the way, for example, the work time of component mounting work performed in each assembly machine is often different depending on each assembly machine, and in this case, in order to improve the efficiency of the entire assembly operation, a specific assembly machine to the next assembly machine When setting a magazine rack, it is desirable to store a predetermined number of magazine racks and perform the operation by batch processing. In such assembling work, it becomes necessary for the operator to carry the magazine rack manually, and when carrying the magazine rack, the stored items such as the printed circuit boards stored in the magazine rack slide off or jump out of the magazine rack. There is a risk that.

Conventionally, in this type of magazine rack, in order to prevent vibration of the frame during conveyance, there is known a structure in which the frame is pressed and fixed with a pressing bar (see Patent Document 1). In addition, there is known a configuration in which the opening of a narrow groove for inserting and storing the stored item is closed with a gate member to prevent the stored item from dropping from the narrow groove (see Patent Document 2). Furthermore, a stopper shaft that can be rotated between a position where the printed circuit board is regulated and a position where the printed board is not regulated is provided in the opening for inserting / removing the printed circuit board to prevent the printed board from protruding and falling ( (See Patent Document 3).

  However, the conventional one is not considered at all when the magazine rack is carried manually. Moreover, a special operation of the stopper shaft or the like is required in order to prevent the magazine rack from being dropped.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a magazine rack capable of regulating the movement of stored items without performing a special operation in accordance with the operation of carrying the magazine rack.

  The magazine rack according to claim 1 has a plurality of pairs of guide rails for holding the stored items, and a main body having at least one end face side of the guide rail open; continuous with the guide rails of the main body. A stopper means having a support rail, and when the main body or the stopper means is lifted, the relative position of the guide rail of the main body and the support rail of the stopper means shifts due to the weight of the main body or the stopper means. Is regulated.

  The guide rail may be formed in a groove shape, a rib shape, or the like, and may have any form that can guide and hold the stored item in a predetermined position. The guide rail and the support rail may be identical in shape, but need not be identical. What is necessary is just to be formed so that it may become continuous and allow the storage / extraction of the stored item.

  According to the first aspect of the present invention, it is possible to regulate the movement of the stored item without carrying out a special operation in accordance with the operation of carrying the magazine rack, and it is possible to prevent the stored item from sliding down or jumping out.

  The magazine rack according to the first embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view showing a magazine rack, FIGS. 2 and 3 are front and side views of the magazine rack, and FIGS. 4 to 6 are perspective views for explaining the operation of the stopper mechanism. In addition, the same code | symbol is attached | subjected to the same part in each figure, and the overlapping description is abbreviate | omitted.

  1 and 2, the entire magazine rack 1 has a substantially rectangular parallelepiped shape and is formed of an aluminum material. The magazine rack 1 is provided with a block of the main body 2 having a U-shaped side surface and a block of stopper means 3 formed in a frame shape that overlaps with the side surface shape. The block of the main body 2 includes a substantially rectangular upper surface plate 4 and a pair of side surface plates 5 provided so as to hang down integrally on both sides of the lower surface side of the upper surface plate 4. A plurality of grooves 6 are formed on the inner surfaces of the pair of side plates 5 in the horizontal direction, extending in the longitudinal direction, and spaced appropriately in the vertical direction. The mutual grooves 6 of the side surface plate 5 form a pair of guide rails that are opposed to each other and store and hold the stored items A such as carriers and printed boards in multiple layers. Therefore, an opening 7 is formed on the side surface side of the main body 2 so as to allow insertion and discharge of the stored items A including the end face opening of the groove 6 constituting the guide rail. Further, a carrying handle 8 is provided on the upper side of the top plate 4, and a slide hole 4 a into which a slide pin 12 described later is loosely fitted is formed at a corner portion.

  The magazine rack 1 is preferably formed of an aluminum material for durability, heat resistance, weight reduction, and the like, but may be formed of a synthetic resin or other metal material. Further, the guide rail may be configured such that another member is attached to the inner surface of the side plate 5 and may be formed in a rib shape. In short, any form that guides and holds the stored item A in a predetermined position may be used.

  Next, the block of the stopper means 3 includes a substantially rectangular bottom frame 10, a prismatic side frame 11 integrally attached so as to stand upright from four corners of the bottom frame 10, and the side frame 11. The slide pin 12 is attached to the slide pin 12. A plurality of grooves 13 are formed inside each side frame 11 at appropriate intervals in the vertical direction. The grooves 13 are paired with the grooves 13 of the side frame 11 facing each other. Further, the groove 13 of the side frame 11 is configured so that the end face opening coincides with the groove 6 of the side plate 5 of the main body 2 described above, and is continuous with the groove 13 of the frame 11 and the groove 6 of the side plate 5. A series of grooves is formed. Therefore, an opening 14 facing the opening 7 of the main body 2 is formed on the side of the stopper means 3. In other words, the opening 7 of the main body 2 and the opening 14 of the stopper means 3 cooperate to allow the stored item A to enter and exit, and insert and discharge the stored item A along the series of grooves 6 and 13. The groove 13 of the frame 11 is configured as a support rail with respect to the guide rail. The slide pin 12 is attached to the upper part of each side frame 11, has a large head portion, and has a stroke portion 12a having a predetermined length.
