DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the examples of FIGS. 1 to 4. On the rack frame 10 at angles .theta.1 and ₁ to 3 degrees in the traveling direction from the transport start end side A to the end side B. A conveyor comprising a pair of guide rails 1 and 1 that are gently inclined and opposed to each other, and a large number of rollers 2 that are rotatably arranged on the guide rail 1 at intervals in the longitudinal direction.
The transfer end portion of the transfer conveyor is equipped with a unloading mechanism 3 that can be sequentially and singly separated from a large number of pallet groups transferred in series, and the unloading mechanism 3 is provided at a transfer end position and fixed for stopping pallets. The stopper 5 and the stopper 6 are provided at a storage length position for one pallet from the end position of conveyance, and the pallet can be placed between the stopper 6 and the fixed stopper 5, and the lifting cylinder 8 can fix the fixed stopper. A guide roll 4 is provided, which is composed of a lifter 7 that can move up and down on the horizontal plane of the upper edge and slides the side surface of the luggage C or the pallet D into sliding contact with the guide rails 1 and 1 at appropriate intervals. .

The guide rails 1 and 1 on both sides at regular intervals have inner and outer rail frames juxtaposed at regular intervals, and a number of rollers 2 are rotatably supported to form a conveying path. The guide rails 1 and 1 on both sides are 1 to 3 with respect to the horizontal plane in the traveling direction from the transport start end to the transport end.
The inclination angle is θ _1, which is 2 degrees, preferably 2 degrees. Further, on both side guide rails 1 and 1, as a mechanism for controlling the traveling speed of the sliding pallet D, the surface is covered with rubber at intervals of a suitable length, and the rollers are rotated at a constant low speed to further rotate. The guide rail 1 is provided with a brake mechanism whose rotation is controlled, for example, one in which a brake roll is axially supported between the rollers 2 and 2 or one in which a friction piece capable of pressing the roller 2 is provided so as to be freely contactable and separable. Elastic plates, such as rubber plates, that are in sliding contact with the pallet may be provided at appropriate intervals.

Thus, while the pallet is being conveyed, the brake mechanism controls the sliding speed to reach the end of the conveyance and stops at the fixed stopper 5, but as the braking mechanism, the support shaft 11 pivots freely. A friction plate 13 such as a rubber plate that prevents slippage is attached to one end of the rocking lever 12
When the roller 14 for operation is provided at the other end, and the roller 14 is pushed down when the pallet D slides through, the friction plate 13 brakes the rotation of the roller 2 pressed against the lower side of the roller 2. Thus, the sliding speed of the pallet D can be controlled so that each pallet reaches the end of conveyance at a slow speed.

As the pallet D, as shown in FIG. 2, a hard sliding plate 15 having an L-shaped cross section and having a smooth surface such as a steel plate or a hard resin plate is fixed over the entire length of its bottom surface and both side surfaces. , The lower surfaces of these hard sliding plates 15 and 15 slide on the rollers 2 and 2 and the brake mechanism so that they are self-propelled in a ski state, and the guide rolls 4, 4

It can be connected to a picking system line consisting of nine.

In this embodiment, when the pallet D on which the articles C are placed is placed on desired side guide rails 1, 1 from the transport start end side A which is the entrance side by a forklift or the like, the pallet is placed on the guide rails 1. , 1 of the guide rails 4 slide while rotating while the guide rolls 4 prevent delusions in the left-right direction, the guide rails 1 and 1 move toward the transport end B by a gentle inclination. At this time, the pallet D runs on the roller 2 in a ski state by the hard sliding plate 15 in an attempt to gradually increase the sliding speed thereof, but the speed does not reach a certain speed or more due to the brake mechanism arranged during the transportation. The deceleration control is performed as described above, and at a slow speed, it reaches the exit port at the end of the conveyance, contacts the protruding fixed stopper 5, and stops. In addition, the subsequent palette D
Comes into contact with the preceding pallet and stops, so that a large number of pallets are sequentially accommodated in the guide rails 1 and 1 on both sides in series. Next, in order to take out the pallet D on which the article C is placed, the pallet D placed on the lifter 7 at the end is lifted by the lifter 7, and the stopper 6 is also raised to receive the subsequent pallet D and move forward. Without moving, the lifter 7 is stopped at the upper edge height position of the fixed stopper 5, and the lifter 7
After carrying out the upper pallet, the lifter 7 is lowered and the stopper 6 is also lowered along the load C and returned to the original position.
