For example, when the motor of the drive 5 of the conveyor device 1 is overloaded and the controller 10 detects the occurrence of overload by the sensor unit 6, the error code of the overload occurrence is searched and "5", for example, is retrieved. The search is performed, the error code is transmitted to the controller 10 of the end conveyor device through the adjacent controller 10, and "5" is displayed on the digital display 23.

When the reset switch 16 is operated after the occurrence of this error, the error code on the digital display 23 is switched to continuous display, and the buzzer 24 stops ringing. When the error state is restored, the controller 10 of the conveyor device 1 in which the error has occurred transmits a restoration signal to the controller 10 of the end conveyor device through the adjacent controller 10 and the controller of the end conveyor device is transmitted.
In response to this restoration signal, 10 turns off the error display lamp 25, and the display on the digital display 23 disappears. If the recovery signal is not confirmed, the error display lamp 21 continues to light and the error code is continuously displayed on the digital display 23.

As described above, each completely independent conveyor device 1 having the common software package 11 can be freely registered in both the master station and the slave station. When the transport table is created, the rotation direction of the roller (the driving direction of the conveyor body 2) and the presence / absence of driving of the branching device 9 are set by the designated transport data, and the transport route is automatically set. Therefore, the load flow of the entire conveyor equipment is automatically set, and even if the completely independent conveyor equipment 1 is freely arranged, the transportation equipment can be constructed without changing the software, and the conveyor equipment 1 is relocated. , Removal and expansion can be done easily.

Further, the loading / receiving of the load can be set from either of the conveyor devices 1 at the ends, and the starting / stopping can be performed, and the operability can be improved. Further, the load can be freely sent back.

Since the branching device 7 is constructed as a completely independent single unit, it can be installed at any place,
The branching / merging of the conveyor transportation facility can be set freely. In the above embodiment, the unique number is registered in the end conveyor device 1, but it is also possible to register it in the intermediate conveyor device 1. You can also carry in and out.

In the above embodiment, the registration number of the conveyor device 1 is automatically stored in each port 25 of the controller 10. However, for example, a setting device or the like is used to directly (manually) directly register each port 25. It is also possible to store it. Further, when the transport destination is designated by the registration number of the conveyor device 1 without creating the transport table, the port 25 storing the registration number that matches the registration number of the conveyor device 1 of the designated transport destination is stored. It is also possible to drive the conveyor body 2 by searching and determining the driving direction of the conveyor body 2 based on the searched port direction.

As described above, according to the first aspect of the present invention, in the determination means of the controller of the conveyor device,
The conveyor data is set by determining the driving direction of the conveyor body from the transfer data set from the console or the transfer data input from the conveyor device placed adjacently through the connecting means and port. The transfer route and the load transfer direction are set, and even if the conveyor device is freely arranged, the conveyor transfer facility can be constructed without changing the software, and the transfer, removal and extension of the conveyor device can be easily performed.

According to the second aspect of the invention, in the determining means of the controller of the conveyor device, the function starts when the adjacent conveyor devices are connected by the connecting means, and the connecting means from the adjacently arranged conveyor devices, By determining the driving direction of the conveyor body from the transport data input through the port, the transport data and the load transport direction of the entire conveyor equipment can be set by setting the transport data. Conveyor equipment can be constructed without changing the software, and it is possible to easily move, remove, or add conveyor equipment.

According to the third aspect of the invention, when the conveyor of the controller of the conveyor device is designated by the registration number of the conveyor device, it coincides with the registration number of the conveyor device of the instructed destination. By searching the port in which the registration number is stored and determining the driving direction of the conveyor main body based on the searched port direction, it is possible to set the transport route and the load transfer direction of the entire conveyor equipment. Therefore, even if the conveyor device is freely arranged, the conveyor transfer facility can be constructed by storing the registration number of the conveyor device in each port without changing the software, and it is easy to move, remove or add the conveyor device. You can Further, the cost can be reduced and the construction period can be shortened.

According to the fourth aspect of the invention, the determining means of the controller of the conveyor device stores the registration number registered in the conveyor device at the input port when the registration number is transmitted and received, and the registration stored at each port. By creating a drive direction table of the conveyor device from the numbers and determining the drive direction of the conveyor main body based on this table, it is possible to set the transfer route of the entire equipment and the transfer direction of the load. Even if they are arranged freely, it is possible to construct a transfer facility without changing the software, and it is possible to easily move, remove, or add conveyor devices. Further, the cost can be reduced and the construction period can be shortened.
