Description

Description: TECHNICAL FIELD The present invention relates to a vertical transporter configured to freely transport a transport case capable of accommodating an object to be transported in a vertical direction, and particularly to a vertical transport of the transport case. The present invention relates to a carry-in station for carrying into a machine.

<Prior Art> As one of the conventional vertical transfer machines, there is one in which a transfer case is configured to be vertically movable by being mounted on a moving body connected to a chain that circulates vertically. The moving body in this type of vertical transporting machine has such a size and shape that a pair of endless belts of a carry-in station, which will be described later, can pass through the space formed by the inner portion of the guide roller and the stopper.

On the other hand, in the carry-in station, a pair of endless belts each configured to move in the direction for pulling in the carrying case are arranged to face each other, while the carrying-in path of the carrying case near the carrying-in port in the station A guide roller for smoothly carrying in is arranged, and a stopper for stopping the carried-in carrying case at a predetermined position is arranged at the inner part of the endless belt. Then, the carrying case carried into the carry-in station from the carry-in port reaches the endless belt while being guided by the guide rollers, and rides in a state where the bottom end of the leading end straddles both endless belts. Subsequently, the transport case is drawn into the carry-in station by the rotational driving of both endless belts, hits the stopper, and stops at a predetermined position to complete the carry-in operation. Next, the moving body that moves upward along the vertical conveying path of the vertical conveying machine lifts the conveying case on the endless belts from below, and vertically conveys the conveying case while the conveying case is on the moving body. . It should be noted that this carrying-in station is configured so that, when the carrying case is not carried in, both endless belts slide in the direction away from the carrying-in position and do not interfere with the movement of other carrying cases passing therethrough. Some were done. The guide roller and the stopper are fixed in position so that they do not slide.

<Problems to be Solved by the Invention> In the above-described conventional carry-in station, when the size of the carrying case to be used is a certain size or more, the guide roller and the stopper obstruct passage of the carrying case. Therefore, even if the guide roller and the stopper are slid outward to expand the space through which the carrying case passes, the carrying equipment is provided with a carry-out station adjacent to the carry-in station. Therefore, it is impossible to secure a space for moving the vertical carrier unless the size of the vertical carrier is increased, and it is difficult to reduce the occupied area of the vertical carrier and to use carrier cases of various sizes. there were.

The present invention aims to provide a solution to this problem.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention is configured such that, for example, a pair of endless belts 12 and 12 serving as a loading / unloading pedestal has a transport case a.

On the other hand, a roller arm 16 having a guide roller 15 attached to the tip thereof is fixed to the one rotating rod 8, and a stopper arm 18 having a stopper 17 attached to the tip thereof is fixed to the other rotating rod 9. As configured.

<Operation> The carrying case a carried into the carry-in station 1 from the carry-in port 4 reaches both endless belts 12 and 12 while being guided by the guide rollers 15, and the bottom end of the carrying case a straddles the endless belts 12 and 12. get on. Then, the carrying case a
Is drawn into the carry-in station 1 by the rotational drive of both endless belts 12, 12, hits the stopper 17, and stops at a predetermined position. Next, the moving body 21 moving upward along the vertical conveying path of the vertical conveying machine 2 lifts the conveying case a riding on the endless belts 12 and 12 from the lower side and conveys it upward. Further, in the carrying-in station 1, when the carrying case a is not carried in, both rotary rods 8 and 9 are rotationally displaced upward, so that the mounts 11 and 11 and both endless belts 12 and 12 thereof, and the guides. The roller 15 and its guide arm 16 and the stopper 17 and the vertical arm 18 rotate integrally and are displaced obliquely upward, so that the moving space of the passing transport case a can be expanded.
