Sailor – RZ-Σ Series

A full servo robot of advance function
■Product Introduction

3 or 5axes full servo traverse robots.
A totally utilized of servo performance, high precision injection molding machine standard model.

More Rigidity !

A high rigidity more than any models
before achieved overall.
The shaking and the noise are greatly decreased,
and durability has increased further, too.

Refined Design !

Rack & pinion mechanism is adopted for the horizontal parts.
It becomes aneat form with no ball screw.

Operator Friendly !
7inch wide display is compact, light, and easy to operate. It makes your setup time greatly shorter than ever. Functions such as the data edits and the data storage are enhanced further.
Also, “Very First in the industry” the wireless handy pendant can be used.(optinal)
Take-Out Dry Cycle 0.8 seconds
Dry Cycle 5.0 seconds
New Controller

Mypro Function
With this software, your original program,
like Position, Timer, Input/Output, etc.
can be added freely.(More→)
Login Function
The administrator and ten(10) other users can be registered. The operation level of five strages can be set to each user.
Name Edit Function
Default names of teaching data and timer can be changed using keybord on the screen. Even when the robot of two or more manufactures is used at your factory, names can be united.
Collision Prevent Function
It automatically calculates max/min values to prevent the collision of parts arm, runner arm, and runner arm with wrist turn when ten key teaching.
Each axis operation can be done actually feeling it at the teaching. USB-Data Transfer
It equips with 2 slots of USB ports. The mold data can be saved in USB drive. and the backup of data is eazy. The alarm and the operation history can be saved in USB drive too.
It is a function with a high extendibility to the important of productivity and the process controll.
Web Function
The situation of the site can be managed by connecting LAN (Wireless LAN is also acceptable ) and the USB camera in the office via the internet.
Wireless Function
Wireless Handy Pendant
Wireless telecommunications with the handy pendant become possible by installing a wireless unit in the pendant. One(1) wireless pendant can control multiple robots. Because it’s a wireless, adjustment of position, timer, speed, etc. can be done from non-operator side easily.
