BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravity feed type shooter rack (fluid shelf) which is installed near an assembly line in the automobile or electrical machinery industry and stores relatively lightweight assembly parts in a pickable manner. .

[0002]

2. Description of the Related Art A fluid shelf having a plastic conveyor (plastic conveyor) rail is the mainstream, but recently, it has been costly and personally spilled (a lightweight, bare container without putting relatively large parts in a container. A shooter rack that uses a pipe material for shooters, which is coated with a synthetic resin with good slipperiness on the outer circumference of a thin steel pipe, as a shelf rail is known because of its compatibility with the one that does not require a storage container and its recovery process. (See Japanese Utility Model Publication No. 1-169518). In this shooter rack, for example, two rectangular side frames made of a pipe material coated with a synthetic resin on the outer periphery of a thin steel pipe are erected so as to be appropriately separated, and the lower portion and the upper portion are connected to each other by the pipe material. A plurality of left and right connecting rods made of the same pipe material are appropriately connected to form a shelf frame, and rail support rods made of the same pipe material as the pipe material are formed in multiple stages at the front, middle and rear parts of the shelf frame. Two pieces of shooter pipe material, which are laterally mounted and covered with a synthetic resin with high slipperiness such as high-density polyethylene or nylon, are attached to the outer circumference of the thin-walled steel pipe between the rail support rods at each part, with a forward sloping slope. In addition, it has two vertical columns of shelf rails that are mounted at intervals such that articles (assembled parts) do not drop.

[0003]

However, in the conventional shooter rack, although it is more advantageous in terms of cost than the one using the plastic control rail, in order to obtain a good downhill, the slope of the shelf rail is 3 ° of the plastic rail
Compared to the front and back, 10 to 15 ° is required for relatively heavy items, and 15 to 30 ° for single lightweight items by sinking, which inevitably reduces the number of shelves and reduces storage efficiency. There is. On the other hand, in order to improve the storage efficiency, the slope of the shelf rails should be made smaller, but the sliding performance will decrease, so to compensate for this, shake the entire shelf every time you take out the item, shake it from the outlet side, Has to be pulled toward the front by the hook rod or pushed by the supplier of the article with the push rod, resulting in a decrease in work efficiency due to useless movement of the worker. Then, this invention aims at provision of the shooter rack which can raise storage efficiency, without causing a fall in work efficiency accompanying a useless operation of a worker.

[0004]

In order to solve the above-mentioned problems, a shooter rack of the present invention is provided with two side frames made of a pipe material in which a synthetic resin is adhesively coated on the outer circumference of a thin-walled steel pipe so as to be appropriately separated from each other. And the lower and upper parts thereof are appropriately connected by a plurality of left and right connecting rods made of the same pipe material as the above-mentioned pipe material to form a shelf frame, and at least the front, middle and rear parts of the shelf frame are formed. Rail supporting rods made of a pipe material similar to the above pipe material are laterally laid in multiple stages at the front and rear portions, and at least between the rail supporting rods at the front and rear stages, the outer periphery of the thin-walled steel pipe has good slipperiness. Two shooter pipe materials coated with synthetic resin with a downward slope
And the shooter rack having at least two columns of shelves rails formed by mounted at intervals item does not fall, the
An intermediate frame similar to the side frame is provided between the row rails of the shelf frame.
In addition, at least the front and rear rail support rods of the front, middle and rear portions are connected to each other by the front and rear portions of the intermediate frame , and any of the front, middle and rear portions is connected. It is characterized in that one vibrator is attached to the rail support rod. Further, it is preferable that each of the rail supporting rods is divided between the shooter pipe members of the shelf rails of each row.

[0005]

In the above means, the vibration of one vibrator is efficiently transmitted to each shelf rail via the intermediate frame and each rail support rod, and promotes the sliding down of the article. Further, by making each rail support rod divided between the shooter pipe members of the shelf rails in each row, the vibration applied to the shelf rails can be amplified.
