[Industrial applications]

  This invention relates to an article transport device.

[0002]

[Prior art]

  Conventionally, an article conveying apparatus of this kind as shown in FIG. 3 has been known. That is, An article transporting vehicle 30 traveling along the traveling passage 31 and a vehicle provided along the traveling passage 31 are provided. The unloading station 32 that has been unloaded, and the unloading station 32 to the left of the An unloading conveyor 33 whose end is located and a load provided in the middle of the traveling passage 31. The loading station 34 and the front end is located on the left side of the loading station 34 And a loading conveyor 35 for loading and unloading the front end of the unloading conveyor 33. The rear end of the conveyor 35 coincides with or is substantially equal to the common virtual line L parallel to the traveling passage 31. It is known that it was made to hit.

[0003]   In the article transfer device, the front end of the unloading conveyor 33 and the loading conveyor So that the rear end of 35 coincides with or substantially coincides with the common virtual line L parallel to the traveling passage 31. That is, the front end of the unloading conveyor 33 and the loading conveyor 35 The rear end is adjacent to the forklift and hand pallet. A truck or the like receives the article W from the unloading conveyor 33, and vice versa. It is possible to efficiently carry out the work of loading the articles W on the loading conveyor 35. There is an advantage.

[0004]

[Disadvantages of the prior art]

  On the other hand, the conventional article conveying device has the following drawbacks. That is, the traveling passage 3 An unloading station 32 and a loading station 34 are separately provided in the middle of 1. Since it was a cargo, when carrying out unloading and loading continuously, the article transport vehicle 30 Stop at unloading station 32 and stop at loading station 34 Had to do, i.e. had to stop twice Therefore, there was a drawback that the operating efficiency was poor.   Further, instead of the article transporting vehicle 30, an overhead type article transporting device, that is, an upper portion The guide rails provided on the When using a device that has a lifting platform that can be lifted up and down, However, the same drawback, that is, the traveling vehicle must be stopped twice, and the operating effect is that much. There was a drawback that the rate was poor. Also, use this overhead type article carrier If you do this, you have to do the work of lowering and raising the lifting platform twice. There was a drawback.

[0005]

[The purpose of the device]

  This invention was made to solve the above-mentioned drawbacks.

[0006]

【Example】

  The present invention will be described below based on two embodiments shown in the drawings.   Example 1 (see FIG. 1)   The same members as those of the conventional device are designated by the same reference numerals.   The article transport device includes an article transport vehicle 30 that travels along a travel path 31, and a travel path. The article transfer station 1 provided in the middle of 31 and this article transfer station 1, an unloading conveyor 33 having a rear end located on the left side, and the article transfer station. Loading container that has a front end located on the right side of the vehicle 1 and crosses the traveling passage 31 A), and the front end of the unloading conveyor 33 and the rear of the loading conveyor 2 It is designed to be adjacent to the edge. Loading container that crosses the passage 31 (A) An article transport vehicle 30 traveling in the traveling passage 31 and an article W placed on the article transportation vehicle 30. Of course, it is designed not to collide and buffer. The carrier of the article carrier 30 Is composed of a drive conveyor 3 whose conveying direction is the left and right direction.   The conveying surface of the driving conveyor 3 is lower than the front end of the loading conveyor 2, The rear end of the unloading conveyor 33 is lower than the conveying surface of the conveyor 3.

[0007]   A stopper 4 is provided at the front end of the loading conveyor 2 and is movable up and down. This The stopper 4 of the operation of temporarily stopping the articles W at the front end of the loading conveyor 2. It has something to do.   The unloading conveyor 2 is used as the unloading conveyor, and the unloading conveyor 33 is used as the unloading conveyor. It may be a stacking conveyor.

[0008]   The device of the first embodiment has the following functions.   When the article transport vehicle 30 on which the article W is placed stops at the article transfer station 1, A method in which the drive conveyor 3 of the article transport vehicle 30 unloads the article W to the conveyor 33 Driven in the direction, the article W is sent to the unloading conveyor 33. At the same time or A little later, the stopper 4 descends, and the article W stopped by it (Different from the article W placed on the article transport vehicle 30) is the drive coil of the article transport vehicle 30. When the articles W are completely transferred onto the drive conveyor 3 and transferred to the conveyor 3, the drive conveyor 3 is When stopped, the article transport vehicle 30 starts traveling.

[0009]   Example 2 (see FIG. 2)   The article transport device includes a guide rail 11 provided above and a guide rail 1 1. A traveling vehicle 12 traveling along 1 and an elevating and lowering provided on the traveling vehicle 12 so as to be vertically movable. Loading platform 13 and article transfer station 1 provided below the guide rail 11. 6 and an unloading container whose rear end is located on the left side of the article transfer station 16. A and a loading container whose front end is located on the left side of the article transfer station 16. The bearer 18 and the front end of the unloading conveyor 17 and the loading conveyor 1 The rear end of 8 is adjacent.

[0010]   The rear end of the unloading conveyor 17 is made lower than the front end of the loading conveyor 18. ing.   The hoisting and loading platform 13 is driven by a drive conveyor 20 whose transport direction is left and right. It is configured.   A stopper 21 is provided at the front end of the loading conveyor 18 and can be raised and lowered. . The stopper 21 temporarily stops the article W at the front end of the loading conveyor 18. It has the effect of causing.

[0011]   The device of the second embodiment functions as follows.   The traveling vehicle 12 on which the article W is placed on the lifting platform 13 (driving conveyor 20) is moved. When stopped above the loading station 1, the lift platform 13 that had been raised until now will be lowered. The loading surface of the drive conveyor 20 lower than the front end of the loading conveyor 18 Then, the conveyor 17 is stopped so as to be positioned higher than the rear end of the conveyor 17. After that, the drive controller Since the bear 20 drives the article W in the direction of unloading the article W to the conveyor 17, Are sent to the unloading conveyor 17. At the same time or slightly later, The article W (the drive conveyor 2) that has been stopped by the par 21 descending 0 is different from the article W on the drive conveyor 20. Is completely placed on the drive conveyor 20, the drive conveyor 20 stops and the lifting platform 13 ( When the drive conveyor 20) rises, the traveling vehicle 12 starts traveling.

[0012]

[Effect of device]

  The present invention has the following effects due to the configuration as described above. .   An unloading conveyor whose rear end is located on one side of the article transfer station; It has a loading conveyor with the front end located on the other side of the goods transfer station. You can unload and load goods at the goods transfer station at the same time. Therefore, the operating efficiency can be increased accordingly.   In the invention of claim 3, the work of lowering and raising the lifting platform only needs to be done once. From this point as well, the operation efficiency can be improved.
