Description

[Detailed description of the invention] Industrial application field The present invention can be used to move from a shelf such as a three-dimensional shelf or a rotating shelf to a loading platform of a loading/unloading machine, or from a loading platform to a shelf booth, or between the loading platform and another loading platform. The present invention relates to a container transshipment device provided on the loading platform for transshipping containers and the like.

Prior art Three-dimensional shelves with a large number of shelf booths arranged vertically, horizontally, and horizontally are arranged in pairs with their frontage surfaces facing each other, and a shelf passage formed between these three-dimensional shelves is arranged parallel to the frontage surfaces. Shelving equipment has been well known in the past, in which a loading/unloading machine that can be moved horizontally is provided, and a loading platform that can be raised and lowered up and down is provided on the loading/unloading machine, and containers are taken in and out of the shelf booth via this loading platform. ing.

In addition, multiple horizontally arranged annular shelves are provided vertically, and containers are stored in each shelf space of each shelf so that they can be rotated along the movement path determined by the shelves. Shelving is also well known in the past, and in this carousel as well, containers are taken in and out of the shelf booth via a loading platform provided on a loading/unloading machine.

In such a three-dimensional shelf or rotating shelf,
An engaging pawl that can move back and forth toward the frontage surface of the shelf is provided on the loading platform, and a handle is provided on the end surface of the container to be stored in each shelf booth, and the engaging pawl and the handle are engaged. The container is pulled out from the shelf space onto the loading platform, and the end face of the container is pushed by the engaging claw to push the container into the shelf space. The handle is usually in the shape of a hook with an open bottom, and the engaging pawl rises from the open bottom and engages with the handle.

In the conventional container transfer device as described above, the engaging claw is required to perform two types of movement: vertical movement for engaging with the handle of the container, and forward and backward movement for pulling out and pushing the container. However, the driving device and control device for the engaging pawl have to become complicated.

Therefore, the present applicant previously proposed a relatively simple structure that allows container transshipment in a series of continuous operations using one drive source, in Utility Application No. 59-2286 (Utility Model Application No. 117307-1981). We proposed an efficient container transshipment device.

This container transshipment device is installed on the loading platform,
A guide rail member arranged perpendicularly to the frontage surface of the shelf booth, a sliding member that slides back and forth guided by this guide rail member, and a wheel provided along the guide rail member between the front and rear wheels. a pair of flexible members arranged horizontally, one end of which is pivoted to the sliding member so as to be slidable in the horizontal direction, the other end of which is provided with an engaging part that engages with the handle of the container; It consists of a pair of arm members whose portions are pivotally connected to the flexible member, and a drive source that drives one of the wheels.

Problems to be Solved by the Invention However, in the container transshipment device disclosed in the above-mentioned Utility Model Application Publication No. 117307/1983, flexible members are provided on both sides of the guide rail member, and the pair of arm members Since the intermediate portions are respectively connected to the respective flexible members, the structure is relatively complicated and the number of parts is large, and the overall weight of the carrier tends to be correspondingly heavy. Furthermore, since the pair of flexible members must be given motion that is consistent with each other, the drive mechanism for the flexible members also becomes complicated.

Therefore, the present invention aims to further improve such a container transfer device to simplify the structure and reduce the weight.

Means and Effect for Solving the Problems Therefore, in the present invention, the container stored in the shelf booth can be lifted onto the loading platform by engaging the engaging piece with the handle provided at the end of the container. A container transloading device installed on the loading platform for taking out or storing containers from the loading platform into a shelf booth, comprising a guide rail member disposed perpendicularly to the frontage surface of the shelf booth, and a guide rail member that is guided by the guide rail member. a sliding member that slides back and forth; and a sliding member provided on the left and right sides of the sliding member, one end of which is pivotally pivoted to the sliding member horizontally and the other end engaged with the handle of the container. and a pair of arm members each having a mating engagement piece, wherein the pair of arm members is moved symmetrically in response to the swinging movement of one arm member on the sliding member. an endless flexible member is disposed horizontally between the front and rear wheels along one side of the guide rail member, and the flexible member A drive source is provided which pivotally connects the intermediate portion of the arm member on the corresponding side and drives one of the wheels.

In the container transshipment device of the present invention, as a flexible member such as a chain disposed along one side of the guide member travels, one arm member connected to the flexible member is moved. The sliding member moves back and forth while being guided by the guide rail member. When the connection point between the arm member and the flexible member rotates along the front wheel, the arm member swings horizontally about the pivot point with the sliding member, and accordingly The engagement piece at the tip of the arm member also moves laterally and engages and disengages from the handle of the container from the horizontal direction.

At this time, the other arm member that is not connected to the flexible member also moves in the opposite direction to this arm member in response to the swinging movement of the one arm member due to the engagement relationship with the one arm member. It swings, and the engagement piece at the tip moves laterally to engage and disengage from the handle of the container from the horizontal direction. That is, both arm members move forward together with the sliding member in a V-shaped open state, and the connection point between one arm member and the flexible member rotates along the front wheel. At the front end position, both arm members swing in opposite directions and become parallel to each other, and at this time, the engaging pieces at the tips of each arm member engage with the handle of the container from both sides. After the connecting point passes the wheel, both arm members move backward while maintaining the parallel state, and the container is pulled out onto the loading platform.

As described above, in the present invention, by driving the only series of flexible members disposed on one side of the guide rail member, the pair of left and right arm members can engage and disengage from the container handle. Since the container is pulled out and pushed in, the structure is simple, and the number of parts is reduced, making it possible to reduce weight and cost.
