Abstract

PURPOSE:To aim at making small and lightweight a cargo transfer device for introducing containers, at stabilizing conveying force and as well at making the transfer of cargo safe, by providing such an arrangement that a drive wheel is pressed to roll on the inside of a part of a looped strech member which opposes a cargo transfer surface and to which tension and braking force are exerted. CONSTITUTION:When one end of a container B comes above a notched hole 4, a motor 33 rotates in the direction (d) to drive and rotate a drive wheel 23. At this time the drive wheel 23 moves in the direction (e) if a timing belt 9 is braked by means of members 12, 13, and a timing belt 9 is lifted up to be pressed against the bottom surface of the container B. With this arrangement the rolling of the drive wheel 23 is restrained, and the torque of the motor 33 convercomes the braking force so that the timing belt 9 creates endless drive to transfer the container B in the direction (f). After the container B being passed the drive wheel 23 is again lifted to its topmost position where the motor 33 is reversed to return. With this arrangement, the transfer device may be made small, lightweight and safe, and as well variation in the amount of feed may be prevented.

作業者がその切欠孔に足をとられるおそれがあった。By the way, in the conventional cargo conveyance device, a notch is provided in the floor of the lower differential, and a drive roller is disposed in this notch so that it can be protruded and retracted. And the container is mentioned above! , when the container is drawn into the IJ notch, the drive roller is made to protrude from the notch so that it can contact and support the bottom surface of the container, and in this state, the drive roller is rotationally driven to open the container. It is designed to be transported in a fixed direction. However, the conventional roller has a complicated structure because it includes a mechanism for lifting and locking the drive roller to a certain height. Therefore, there was a drawback that TIf,p was too large for aircraft parts that required weight reduction. In addition, with such a device, the drive roller can only be held up to a certain height, so if the height of the bottom of the container changes for some reason, the force with which the drive roller presses against the bottom changes, causing the conveying force to change. There is a problem that changes. Furthermore, with such a product, it is necessary to provide a relatively large p-notch in the area of the floor that corresponds to the movable range of the roller.
There was a risk that the worker would get stuck in the notch.

It is possible to reduce the size and weight of the cargo without causing fluctuations in the conveying force, and to avoid the presence of large spaces that could cause workers to get stuck on the floor. The purpose is to provide a conveyance device.

A second tension applying mechanism 36 is used to apply a constant tension to the timing belt 35. This tension applying mechanism 36 is configured such that a tension roller 38 held at the tip of an arm 37 is brought into elastic contact with the outer periphery of the timing belt 35. Note that the braking mechanism 12.13
The braking force is set to a sufficiently high value with respect to the tension applied by the force applying mechanism 11.36, and as will be described later, until the timing belt 9 comes into contact with the bottom of the container B, the timing The belt 9 is stationary, and the drive wheels 23 can roll while lifting the timing belt 9.35 in the L direction. On the other hand, the output torque of the motor 33 is set to a value sufficient to overcome the braking force of the braking mechanism 12, 13.

In this state, when the container B is carried in from the left side in the figure and its end is positioned in the notch hole 4F, the motor 33 starts rotating in the direction of the arrow d, and the drive wheel 23 is rotationally driven.

In this case, it becomes impossible for the driving wheel 23 to continue moving any further, but since the rotational force from the motor 33 continues to be transmitted, the braking force of the braking mechanism 12 reaches its limit and the timing heald 9 opens an endless run &+
do. Therefore, the container B is also pressed in the direction of the arrow f together with the timing heald 9, and as a result, the container B is transported (see FIG. 3). Note that after the container B has passed, the drive wheels 23 start moving upward again, so a limit switch is provided at the end of the cam groove 28 of the drive wheel guide mechanism 27, and this limit switch installation part When the drive wheel 23 reaches this point, the drive wheel 23 is returned to its original standby position by, for example, reversing the motor 33. If the rotation of the motor 33 is reversed from that described above, the container conveyance direction will also be reversed. When transporting container B from left to right in the figure, tension is applied to the pulleys 5 and 7, so the brake mechanism 12 on the left side in the figure works, and the brake ring 21 of the brake mechanism 13 on the right side acts. This is done so that the engine is idle. Conversely, when conveying container B from right to left in the figure, tension is applied to the pulley 6.8 side, so the right braking mechanism 13 works, and the left braking mechanism 1
The second brake ring 17 is designed to rotate idly.

直接接触させるようにしてもよい。In addition, in the above-mentioned embodiment, a case has been described in which the annular tension member is brought into contact with the bottom surface of the cargo, but the present invention is not limited to such a structure. It is also possible to cover the part that is not covered by the tension member, provide a rubber band or the like in that part, and bring one part of the rubber foot into direct contact with the bottom surface of the cargo.

よい。In addition, in the embodiment of one foot, the case where one annular tensioning member is provided for one drive wheel has been described, but the teaching invention is not necessarily limited to such a thing. A plurality of annular tension members may be provided for one drive wheel, and these may be driven by a common actuating device.

（へ）効果 本発明は、以１．０ような構成であるから、次のような

。Moreover, since the structure is simple and there is no mechanism for locking the drive wheels to be pressed against the cargo at a certain height, it is suitable for use on aircraft where light weight is desired.

きる。In addition, until the braking force of the braking mechanism is overcome, the drive wheel continues to move upward and is pushed against the drive wheel, the annular tension member, or the bottom of the cargo, so the braking force is kept at a constant value. As long as it is controlled, the pressing force will not change even if the height position of the bottom of the cargo changes.
Therefore, it is possible to always exert a constant conveying force.
