DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 2, reference numeral 1 denotes a slat conveyor, which is provided between a driving toothed wheel 2 and a driven toothed wheel 3. It is provided with a stretched endless slat assembly 4 and a motor 7 for driving the driving toothed wheel 2 to rotate via a reduction gear 5 and a chain transmission means 6. The endless slat assembly 4 is provided with transported object supporting means 8 at appropriate intervals, and inside the turning path of the endless slat assembly 4, lift control guide rails 9 and 10 are disposed. Has been done. Reference numeral 11 denotes a transfer object receiving work position set at the starting end position of the transfer object transfer path 12, 1
Reference numeral 3 denotes a transported object delivery work position set at the end position of the transported object transport path 12.

As shown in FIGS. 1 and 3, the endless slat assembly 4 of the slat conveyor 1 comprises slats 15 provided at equal intervals between a pair of left and right endless roller chains 14. The roller chain 14 is stretched between the driving toothed wheel (left and right pair) 2 and the driven toothed wheel (left and right pair) 3 shown in FIG. It is supported by the pair of left and right chain guide rails 16 and rotates. A pair of left and right elevating guides 17 is provided so as to penetrate in the up and down direction on each slat 15A at every conveyed object support pitch.
From the upper end of the arm extending in the front and rear directions 18a, 18
b are arranged in series. These overhang arm members 18a, 1
8b is abutted and supported on the slats 15B and 15C located at the front and rear positions apart from the slat 15A provided with the lifting guide 17 in the transported path 12 for the transported object.

Each of the transported object supporting means 8 is provided with a pair of left and right elevating members 19 supported by a pair of left and right elevating guides 17 so as to be able to ascend and descend, and a pair of upper and lower elevating members 19 provided on one end. The conveyed object support member 20 and a guide roller 21 supported by a horizontal support shaft at the lower ends of a pair of left and right elevating members 19 are provided. The transported object support member 20 is
It is configured so as to fit the size and shape of the transported object W to be handled, and in this illustrated example, four transported object supporting portions 20a are provided.

The elevating control guide rail 9 engages with the guide roller 21 of the transported object supporting means 8 moving on the transported object transporting path 12 to control the height of the transported object supporting member 20. For example, the transported object support member 20 is at the lowest height between the transported object receiving work position 11 and the transported object delivery position 13, and is suitable for working on the transported object W in the intermediate path between the working positions 11 and 13. Object support member 2 at height
The height of 0 is controlled up and down. The lift control guide rail 10 engages with the guide roller 21 of the transported object supporting means 8 that moves in the opposite direction below the transported object transporting path 12 to adjust the height of the transported object supporting member 20. It regulates.

In the conveyor device constructed as described above, when the endless slat assembly 4 is rotated by the drive toothed wheel 2, the upper slats 15A move horizontally in the upper conveying path 12 for the object to be conveyed. The transported object support member 20 is moved up and down by the elevating control guide rail 9 via the lower end guide roller 21 as a result of the elevating member 19 moving integrally with the slat 15A.
It is automatically raised and lowered to the height corresponding to. For example,
At the transported object receiving work position 11, the transported object support member 20 is at the minimum height, and the transported object W is transferred from another facility. The transported object support member 20 that moves in the transport direction in accordance with the rotation of the endless slat assembly 4 is automatically raised to a height suitable for work on the transported object W that is mounted, and at an appropriate position. When it reaches, it can be raised and lowered to another height suitable for the next work.

On the other hand, the elevating guide 17 of the slat 15A moving on the object conveying path 12 has a pair of front and rear projecting arm members 18a and 18b extending in the front-rear direction from the upper end side of the elevating guide 17. , This lifting guide 17
Since it is supported by abutting on the other slats 15B and 15C which are located in the front-rear direction away from the slat 15A provided with, it is supported by at least three slats 15A-15C which are separated in the front-rear direction. , A guide 17 for raising and lowering by a bending moment in the front-rear direction acting on the elevating member 19 of the conveyed object supporting means 8 on which the conveyed object W is mounted,
By extension, the slats 15A provided with the lifting guides 17
Can be reliably prevented from falling in the front-rear direction, and the transported object supporting means 8 can be moved stably. In this way, the transported object support member 20 that has reached the transported object delivery work position 13 is lowered again to the minimum height, and the loaded transported object W is unloaded.

The transported object supporting member 20 of the transported object supporting means 8 which moves in the reverse direction below the transported object transporting path 12,
For example, pull up by the guide rail 10 for elevation control,
The endless slat assembly 4 can be brought to the closest position. Of course, the height control of the transported object support member 20 when moving below the transported object transport path 12 in the opposite direction is performed by a guide roller pivotally supported on the side portion of the transported object support member 20 or the like. It may be carried out by a method of supporting by a guide rail, and in some cases, the guided object support member 20 is lowered by gravity to a lower limit position (from the endless slat assembly 4 without performing forced height control by the guide rail. It can also be moved in a state where it is lowered to the most distant position).

In the above embodiment, one object-to-be-supported member 20 is supported by the pair of left and right elevating members 19 and the pair of left and right elevating control guide rails 9. The numbers of the members 19 and the elevating control guide rails 9 may be changed, and in some cases, one elevating member 19 and one elevating control guide rail 9 may be used for supporting. In any case, one or a plurality of elevating / lowering members 19 supporting one transported object support member 20 are
It is movably supported by one or a plurality of lifting guides 17 provided on one slat 15A. Further, although the projecting arm members 18a and 18b are continuously provided from the elevating guide 17, the slat 15A including the elevating guide 17 is provided.
It is also possible to install from.

[0013]

As described above, according to the conveyor apparatus of the present invention, the object supporting member for supporting the object is moved up and down by the elevating member provided on the elevating guide provided on one slat. Although it is borne as possible, an extension arm member extending in the front-rear direction from the elevating guide or the slat equipped with the elevating guide is provided, and the extension arm member is provided in the object conveyance route. Since it is configured to be supported on a slat that is separated from the slat equipped with the lifting guide in the front-rear direction, the bending moment in the front-rear direction of the transported object supporting means supported by one slat is It can be received by multiple slats at distant positions.

Therefore, in the conventional conveyor device, a long object to be conveyed can be lifted up and down by one slat which must be supported by the object supporting means which is controlled to move up and down separately. Even if it is supported by one supported object support means, an excessive bending moment acts on one slat that supports the object support means, which causes a problem in strength and prevents smooth running. There is no such thing. In other words, in the case of the conventional conveyor device, one conveyor device for conveying a long object to be conveyed must be supported by the object supporting means which is controlled to move up and down separately. It becomes possible to simply configure the transported object supported by one transported object supporting means, and since it is not necessary to vertically move the two transported object supporting means in parallel, the transported object is supported. The raising and lowering control of the means can be performed easily and easily. Therefore, the cost of this type of conveyor device can be significantly reduced.
