Description

  The present invention relates to a merchandise display shelf structure, and more particularly to a merchandise display shelf structure used for a showcase in a convenience store or a supermarket.

  In a showcase at a convenience store or a supermarket, when a product displayed on the front side (front) of the product display shelf of the showcase is taken out, a plurality of items are displayed on the back side (rear) of the product display shelf. A merchandise display shelf is adopted in which merchandise is automatically movable in the front-rear direction from the back side (rear) of the showcase toward the front side (front) of the showcase.

  Many proposals have been made for such merchandise display shelves (for example, Patent Document 1).

  What is proposed in Patent Document 1 is a state in which a plurality of rollers for supporting a product etc. in a direction perpendicular to the moving direction of the product etc. are rotatably supported by and supported by a lower support frame and an upper support frame. It is a transfer device for goods or the like having a form in which at least the top of each roller is exposed upward from the upper support frame. In this form of transfer device, the distance between the axes of the rollers adjacent to each other in the moving direction of the product is at least twice the diameter of the rollers, and the upper support frame is positioned below a virtual plane connecting the tops of the rollers. And a closing flat plate for closing a gap between the adjacent rollers.

  By making the distance between the axes of each roller more than twice the diameter of the roller, when the product etc. moves on the roller, the number of rollers in contact with the bottom of the product etc. is compared with the conventional one. Can be reduced. Thereby, it is said that the resistance on the apparatus side that occurs when goods or the like move on the roller can be reduced. In addition, since the upper support frame has a closing flat plate positioned slightly below the virtual plane connecting the tops of the rollers, the leading end in the moving direction of the product etc. enters the gap between the rollers. It is said that it can be surely prevented from falling. Furthermore, the number of rollers per unit distance in the moving direction of the product etc. is reduced by making the distance between the shafts of each roller more than twice the diameter of the roller as compared with the transfer device of the conventional product etc. It can also reduce the manufacturing cost.

  Further, if the closing flat plate has a structure having a vertical rib that is convex in an appropriate number in the moving direction of the product or the like, the strength against warpage (deflection) in the short direction (width direction) of the closing flat plate is increased. be able to. As a result, when the product or the like is tilted, the tilt can be reliably corrected. In addition, even when the product etc. is moving, even if the bottom of the product may come into contact with the closing flat plate, it is only in contact with the top of the vertical rib, and there is no significant increase in frictional resistance. It can be continued as it is.

Formed on the upper surface of the peripheral wall surface of the roller 3 and on the upper surface of the upper frame 4 positioned between the rollers 3 adjacent to each other in the lateral direction, and protrudes to a height position above the peripheral wall surface of the roller 3. The first protrusion 11 is contacted.

  Therefore, the product can be smoothly moved from the rear to the front.

  In the embodiment shown in FIG. 5 and FIG. 6, it is formed on the upper side surface of the upper frame 4 located between the rollers 3 adjacent to each other in the lateral direction and protrudes to the height position above the peripheral wall surface of the roller 3. The first protrusion 11 is a protrusion that extends in the front-rear direction.

  Instead, a structure in which a plurality of protrusions are formed adjacent to each other in the front-rear direction and formed on the upper side surface 4a of the upper frame 4 positioned between the rollers 3 adjacent in the lateral direction can be employed.

  In the embodiment shown in FIG. 5, the second protrusion 12 formed on the upper side surface 4 a of the upper frame 4 located between the openings 10 adjacent in the front-rear direction is a ridge extending in the front-rear direction. .

  Alternatively, a structure in which a plurality of protrusions are adjacent to each other in the front-rear direction and formed on the upper side surface 4a of the upper frame 4 located between the openings 10 adjacent in the front-rear direction can be employed.

  In the embodiment shown in FIG. 6, the second protrusion 12 is not formed on the upper side surface 4a of the upper frame 4 located between the openings 10 adjacent in the front-rear direction.

  Even in such a structure, the upper frame 4 is mounted on the lower frame 2 from the upper side, and the rotation center shafts 8 and 9 of the roller 3 are rotatably supported by the roller support portions 6a and 6b. And since the upper frame 4 has covered the lower frame 2 from the upper side, as above-mentioned, goods can move smoothly from back to front.

  In particular, if the distance in the front-rear direction of the rollers 3, 3 adjacent in the front-rear direction is smaller than the length in the front-rear direction of the product mounted on the product display shelf, the product is adjacent to the bottom surface in the front-rear direction. The roller 3 or 3 is brought into contact (sliding contact) with the upper peripheral wall surface, and the roller 3 or 3 can be smoothly moved in the front-rear direction.
