工場等においては、多数の物品を保管しておく
必要がある。このような多数の物品の保管に際し
ての入庫、出庫には多大な労力を必要とし、各物
品の管理は複雑で煩わしいという問題があつた。
In factories, etc., it is necessary to store a large number of items. When storing such a large number of articles, a great deal of effort is required to store and take them out, and the management of each article is complicated and troublesome.
近時、物品の入庫作業、出庫作業を完全に自動

ステムの開発が進んでいる。 2. Description of the Related Art Recently, the development of automatic warehousing and unloading systems that completely automates the warehousing and unloading operations of goods and solves the above-mentioned problems has been progressing.
このような自動入出庫システムとしては物品を

を出庫させるようにしたものがある。 Such an automatic loading and unloading system stores articles in a predetermined shelf position and installs a transfer machine at a position to take out the articles from the shelf position, and transports the articles to the transfer machine on a transport vehicle. The items on the vehicle are transferred onto the transfer machine, the items are stored from the transfer machine to a predetermined shelf position, and conversely, the items are taken out by the transfer machine from the predetermined shelf position, and the items are transferred from the transfer machine to the transport vehicle. There is a system in which goods are transferred to the warehouse and the goods are discharged from the warehouse.

実用的ではなかつた。このため搬送車において
は、通常は物品を幅方向にのみ移動させ得るよう
になつている。 The conveyance vehicle has a loading section for articles on a trolley, and a moving device moves the articles on the loading section in a predetermined direction and transfers them onto a transfer machine. Usually, a transport vehicle is provided with bumpers or the like at the front and rear of the cart to protect the cart, so the length in the front and rear direction is longer than the length in the width direction. Therefore, when moving an article in the longitudinal direction, the moving stroke of the article becomes long, and there is a risk that the article will not be placed on the transfer machine, and in order to eliminate this risk, it is necessary to increase the size of the moving device. It is conceivable to make the stroke larger or to make the entire mounting part larger than the cart, but neither of these cases is practical. For this reason, transport vehicles are usually designed to allow articles to be moved only in the width direction.
このような搬送車では移載機が物品の搬送方向
に位置するように、且つ移載機に密接させて停止
させる必要がある。 In such a transport vehicle, it is necessary to stop the transfer machine so that it is located in the transport direction of the article and in close contact with the transfer machine.

る。 In FIG. 6, reference numeral 1 denotes a linear main running path, and a branch running path 2 is formed in the middle of this main running path 1, branching off at right angles, and a station 3 is provided at the tip of the branch running path 2. Reference numeral 4 denotes an automatic guided vehicle, and a roller conveyor 4a that can convey the object in a direction perpendicular to the direction of movement indicated by a white arrow is provided on the upper part of the automatic guided vehicle, and a conveyed object 5 is placed on the upper part of the roller conveyor 4a. be done. In order to transfer the transported object 5 currently placed on the automatic guided vehicle 4 to the station 3,
When the automatic guided vehicle 4 is driven straight and moved from point A to point B, the automatic guided vehicle 4 is turned to the right, enters the branching route 2, and is moved to point C.
Since the transfer direction of the roller conveyor 4a of the automatic guided vehicle 4 is perpendicular to the direction of the station 3, the object 5 cannot be transferred to the station 3. Therefore, it is necessary to turn the vehicle body 90 degrees just for transfer in front of station 3.

があるため夫々の車輪の制御が複雑になり、また
個々の走行用車輪に対してその向きを変えるため

が複雑化する等の問題があつた。 In order to solve this problem, by changing the direction of the running wheels of the automatic guided vehicle 4 to the right angle direction and providing a traversing function, when the automatic guided vehicle 4 moves from point A to point B, the running wheels If the direction is changed to a right angle direction so as to be parallel to the branch running path 2, and the automatic guided vehicle 4 is moved on the branch running road 2 in the direction of the station, the conveyance direction of the roller conveyor 4a of the automatic guided vehicle 4 will match the direction of the station 3. Therefore, it becomes possible to transfer the transported object 5 from the automatic guided vehicle 4 to the station 3. However, since it is necessary to change the direction of the running wheels when traveling straight on the main running road 1 to the right angle direction when moving sideways on the branch running road 2, the control of each wheel becomes complicated, and the control of each wheel becomes complicated. This required a direction control motor to change the direction of the running wheels, which caused problems such as the complexity of their structure.

示すように大きく旋回させる必要があり、走行の
ための広いスペースを必要とした。 Additionally, when storing a large amount of goods, the installation conditions of the transfer machine are generally limited due to space constraints, and the direction in which the transport vehicle is brought in and the direction in which the goods are placed on the transfer machine are not perpendicular to each other. There are many cases. Fourth
The figure is a schematic plan view in such a case, and the direction in which the goods are moved by the transport vehicle H and the direction in which the goods are placed in the transfer machine I are made to match (see the white arrow).
In order to bring the transport vehicle alongside the transfer machine I, it was necessary to make a large turn as shown in FIG. 4, which required a large space for traveling.

されている。 In order to eliminate these drawbacks, each wheel of the transport vehicle H is installed so that its direction can be changed over 360 degrees, allowing the transport vehicle to rotate on the spot (spin turn) and change the axial direction of the transport vehicle. Transport vehicles have been developed that reduce the running space by enabling running (diagonal running) where the traveling direction (longitudinal direction) and traveling direction do not coincide.

ピンターンする。 The operation of the transport vehicle according to the present invention constructed as described above will be explained. This carrier has each drive wheel 52.
With the rotation of the turntable 51 stopped,
When the motor 12 is rotated to rotate the turntable 51, the turntable 51 does not rotate due to the frictional force between the drive wheel 52 and the ground surface, and the cart 10 rotates relative to the turntable 51. Furthermore, when the entire transport vehicle (that is, the traveling section 50 together with the trolley 10) is to be turned, the motors 53 are rotated in opposite directions while the braking device 17 is operated. As a result, each drive wheel 52 rotates in opposite directions, and the turntable 51 rotates on the spot.

Also, no space is required for turning, and the traveling procedure is simplified, making it easy to design an automatic loading/unloading system. This will greatly reduce the time required for loading and unloading. Furthermore, when each drive wheel is rotated in the horizontal direction as shown in Fig. 5C, the distance between the drive wheels becomes small and the running becomes extremely unstable. Even when the wheels rotate, the distance between the drive wheels does not change, allowing stable driving.
