This conventional structure is provided with a roller conveyor (main conveyor) and a pair of chains (conversion conveyors) that are arranged between the rollers of the roller conveyor and that can move up and down with respect to the upper surface of the roller conveyor by vertical swing. There is.

According to such a conventional structure, before the load conveyed by the roller conveyor reaches the branch point, both chains are rotated in either forward or reverse directions, and when the load reaches the branch point, the two chains are rotated. The chains are swung upward around a fulcrum, the upper surfaces of both chains are raised relative to the upper surfaces of the roller conveyors, and the load is transferred to either side. Further, by leaving both chains in the downward swinging position, it is possible to convey the load by the roller conveyor without discharging the load from side to side.

[0004]

However, according to the above-mentioned conventional structure, since the conversion conveyor is a chain type, the conversion conveyor becomes expensive, and depending on the type of load (for example, a cardboard box), Contact, slippage, or catching may cause damage.

Although a structure in which a round belt or a flat belt is adopted instead of the chain is also provided, in the case of a round belt, it is essential to stop the load by abutting because the torsional rigidity is low. A stopper device, etc.
The whole is complicated and expensive. Further, in both the round belt and the flat belt, slip is likely to occur between the pulleys around which these belts are wound, and as a result, unloading cannot be performed properly, and high-speed unloading cannot be expected.

Therefore, according to the first aspect of the present invention, the whole object can be simply and inexpensively constructed in order to transfer the transferred object conveyed by the transfer means at a right angle, and the type of transferred object can be changed. It is an object of the present invention to provide a transfer facility that can be transferred regardless of damage and can perform high-speed and suitable transfer without stopping an object to be transferred.

The transfer and transfer surface can be brought into contact with the transferred object from below to lift the transferred object from the conveyor transfer surface. As a result, the timing belt group can lift and convey them at the same time in an orthogonal manner, and thus can move (branch) to the branch conveying means and convey them.

According to a fourth aspect of the present invention, there is provided the transportation facility according to any one of the first to third aspects, in which the driven toothed wheel is vertically moved between the drive toothed wheel and the driven toothed wheel. It is characterized in that a belt receiver interlocked with is provided.

Is detected and the load is prevented from jamming. At this time, in the transfer means 30, the rotation driving device 6
0 drives the motor 61 to rotate the drive shaft 50 via the output shaft 62, the drive pulley 63, the endless belt 65, and the passive pulley 64. Therefore, the belt drive bodies 40 synchronize the timing belt 43 with each other. Is being rotated.

As described above, when the object 1 to be conveyed is detected by the detecting means 6 and the object 1 to be conveyed is the object 1 to be branched to the orthogonal branch conveyor 70, the time is detected and detected. After the time set by the timer elapses, the cylinder device 67 is extended. As a result, the elevating member 53 is raised, and the group of driven toothed wheels 42 is raised together with the elevating member 53. By raising the driven tooth wheel group 42 in this manner, as shown in FIG.

According to the first aspect of the present invention described above, when the object to be conveyed carried by the roller conveyor is the object to be transferred by the transferring means, the transferring means is operated. Therefore, the transported object can be transported by passing through the transfer means. That is, in the transfer means, the transfer conveyor surface by the timing belt group can be positioned below (retracted from) the conveyor conveyor surface of the roller conveyor by lowering the driven tooth wheel group by the elevating device, so Objects can be conveyed by the group of rollers without passing through the transfer means and passing through the transfer means.

When the object to be transferred is the object to be transferred by the transfer means, the lifting device is moved up to raise the driven tooth group, and the transfer / transfer surface becomes the conveyor transfer surface. In contrast, it can be positioned (projected) upward. At this time, since the lifting device is moved up before the transferred object reaches the transfer position by the transfer means, when the transferred object reaches the transfer position, the transfer transfer surface is moved relative to the transferred object. Can be abutted from below and subsequently lifted from the conveyor transport surface. Therefore, by the timing belt group that is rotated in a synchronous manner, it is possible to convey and move in an orthogonal shape simultaneously with lifting.

At this time, the orthogonal conveyance does not cause damage due to slipping or catching regardless of the kind of the object to be conveyed because the transfer means uses the timing belt group. It can be carried out. Moreover, in the case of a timing belt, since the torsional rigidity is high,
There is no need to stop the transported object by stopping it by using a stopper device, etc., and no slip occurs between the timing belt and both toothed wheels. As a result, the entire transfer device can be configured easily and inexpensively. In addition to this, high-speed unloading can be suitably performed.

According to claim 2 of the present invention described above,
When the object to be transported carried by the roller conveyor is detected by the detecting means and the object to be transported is a material which does not need to be transferred by the transfer means, the transfer means does not operate. It can be transported by passing through the transfer means.
Further, when the transferred object detected by the detecting means is the transferred object branching to the branching / conveying means, the lifting / lowering device is moved up to raise the driven tooth group, and the transfer / transfer surface is moved to the conveyor transfer surface. Can be located above.

According to the third aspect of the present invention described above, when the object to be conveyed branches to the branching and conveying means, the elevating device is operated so that the transfer and conveyance surface is moved upward with respect to the conveyor conveyance surface. The transfer object can be positioned so that the transfer object is brought into contact with the object to be transferred from below, and the object can be lifted from the conveyor object surface. As a result, the timing belt group can lift and transport the belt at the same time in an orthogonal manner, and thus the belt can be transferred to the branch transport means and transported.

Further, according to the fourth aspect of the present invention described above, the downward tooth group in the upper rotation path of the timing belt can be received and guided by the belt receiver, so that the timing belt can always rotate stably. Thus, it is possible to stably and reliably perform the right-angled transfer of the transported object.

Further, according to the fifth aspect of the present invention described above, when the transfer means is incorporated into the conveying means, for example, the lower frame body is attached to the conveyor frame in a state where the driven tooth wheel side and the lifting device side are disconnected. This can be done by inserting the lower frame body in a state of being brought into contact with the conveyor frame from below and then connecting the driven toothed wheel side and the lifting device side. This allows
Arrangement (assembly) of the transfer means, which is separately manufactured and assembled, with respect to the transfer means can be performed simply and easily and at any position in the transfer direction.
