Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a roller conveyor with a turntable for loading and moving containers or pallets for transportation.

[0002]

[Prior art]

 In general, containers are widely used for transporting parts manufactured in a parts manufacturing factory to an assembly factory, and roller conveyors are widely used for moving the containers in a factory or a warehouse.

As a container, a container provided with an opening / closing door on the front is widely used, and a container integrally provided on the bottom portion so that a fork of a forklift can be inserted from any of the front, rear, left and right sides. Widely used.

On the other hand, the roller conveyor is widely used for a pallet-integrated container having two rows of roller parallel to both edges.

[0005]

[Problems to be solved by the device]

 When moving a pallet-integrated container on the conventional roller conveyor as described above, when moving by a forklift from the roller conveyor, the container is sent from each part because the fork insertion direction is limited. In many cases, the direction in which the fork can be inserted is different. For this reason, there is a problem in that at least two end portions of the conveyor for which the forklift is to be used must be open for moving the forklift at the two sides adjacent to each other.

In addition, when taking out the contents by opening the door from the container on the roller conveyor, if the container doors are sent in different directions, the worker has to go to the door side each time. However, even in this case, if the door is not facing the installation location side after taking out the item, there is a problem that the work efficiency is significantly reduced.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a roller conveyor with a turntable that can freely change the direction of a container at a predetermined position on the roller conveyor.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned conventional problems and achieve the intended purpose, the gist of the present invention is to provide two rows of rollers parallel to each other and a top of the rows of rollers between the rows of rollers. The present invention resides in a roller conveyor with a turntable that includes a turntable that can be raised and lowered from a low position to a high position and that is rotatable, and a lift mechanism that raises and lowers the turntable.

[0009]

[Action]

 This roller conveyor with a turntable has the height of the upper surface below the top of the roller row when the turntable is descending, and containers and pallets can move on the roller row in the same way as a normal roller conveyor. Then, by stopping the container or pallet at the position on the turntable and raising the turntable by the elevating mechanism, the container or pallet is loaded on the turntable and can be raised and swiveled. Allows you to swivel horizontally and head in the direction you need.

[0010]

【Example】

 Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, 1 is a roller conveyor main body, and 2 and 2 are roller rows provided on both edges of the main body 1. Each roller row 2 has a large number of conveyor rollers 2a, 2a, ...

The roller conveyor main body 1 is provided with a turntable 5 in the central portion of both roller rows.

As shown in FIG. 3, the turntable 5 has a vertical support shaft 6 fixed to the center of the lower surface thereof, and the support shaft 6 supports a thrust bearing 8 and a radial bearing 9 with respect to the lifting block 7. It is rotatably supported through the bearing. The elevating block 7 is fitted in a guide cylinder 10 so as to be movable up and down, and the guide cylinder 10 is integrally projected on the upper surface of a base plate 11, and the base plate 11 is fixed on the bottom plate 1a of the roller conveyor main body 1. ing.

The turntable 5 is adapted to be housed in a circular hole 3 formed in the top plate 1b of the roller conveyor main body 1. When the turntable 5 is in a lowered state, the top surface of the turntable 5 is the top plate 1b. It has the same height as the upper surface, and when it is in a raised state, the upper surface is higher than the top of each roller 2a of both roller rows 2 1, 2.

The turntable 5 is moved up and down by a lifting mechanism 15. The lifting mechanism 15 uses a lever 16, and the center portion of the lever mechanism 16 is used as a fulcrum 17, the tip is bifurcated, and the ends 16a and 16b are provided with a bolt 18 and a bearing ring 19. And is pivotally attached to the lifting block 7. Further, the rear end of the lever 16 is projected to the outside of one of the roller rows 2, and the pedal 20 is fixed to the upper surface thereof. Further, a stopper 21 is provided at a side surface position on the rear end side of the lever 16 so that when the pedal 20 is depressed and pushed down, it is automatically pulled to the lower side of the stepped portion 23 by a spring 22 which is constantly pulled. The rise is blocked, and the turntable 5 is kept in the raised state.

In the roller conveyor with a turntable configured as described above, when the turntable 5 is at the lowered position, the conveyor rollers 2a, 2a of the two roller rows 2, 2 ... You can move freely. Then, the transported object is stopped on the turntable 5, and the lifting block 7 is pushed up via the lever 16 by depressing the pedal 20, and the turntable 5 is raised above the tops of the respective conveyor rollers 2a, 2a. It is lifted and the load is lifted. As a result, the transported object can be freely swung together with the turntable 5, and the worker can swivel in any direction.

[0017]

[Effect of device]

 As described above, the roller conveyor with a turntable according to the present invention is provided with a turntable that can be moved up and down by a lifting mechanism between two rows of rollers, and is provided with a turntable that is in the middle of moving or at the end / starting end of a moving object. In the section, the direction of the conveyed goods can be freely changed by a simple operation, the articles can be taken out from the container from the side where it is necessary, and the workability is remarkably improved. The insertion direction of the can be always fixed, and the narrow space can be used effectively.
