RA-α-75S-HS, RA-α-150S-HS

Ultra-high-speed take-out robot for small-size moulding machine

Pursuit of higher rigidity and adoption of linear motor on kick axis realize stable high-speed operation. RA-α-75/150S-HS, applicable for a moulding machine with a clamping force 30~180 ton, records take-out dry-cycle time at 0.38 second. Therefore this machine contributes to manufacturing efficiency by shortening the extraction cycle time remarkably. Furthermore, this robot is equipped with E-touch Web controller, highly-functional controller for network.

※1 - Linear motor is adopted on kick axis. People wearing medical equipment such as a pacemaker must not approach the magnet of linear motor. Furthermore, please do not take magnetic recording items with you such as a magnetic card, electronic watch and floppy disc because there is a possibility that the items break down due to magnetization.
※2 - This specification is for decreasing full cycle time by increasing the speed of all axes: kick, vertical and traverse axis.
※3 - Based on dry-cycle measurement conditions specified by Yushin.

  • The robot is equipped with a flexible yet user-friendly E-touch Web controller and includes Lead Through Teaching software and networked operation.

  • Twin linear servo motors adopted. RA-a-HS series robots use twin linear motors for the kick axis, which reduce minimal dust generation for clean room compatibility.

  • The steel robot traverse beam provides superior rigidity. To meet customers demands for high accuracy and low vibration when performing value-added operations.

  • Latest controller. The latest E-touch Web controller is provided as standard, achieving flexible and expandable operation using Windows as its operation system.

Option List

OptionExplanation
Applicable Models
Vacuum suction circuit In addition to a standard product vacuum suction circuit, expansion is possible up to 4 vacuum circuits.
All models
Product chuck circuit In addition to a standard product chuck circuit, either 1 or 3 more circuits can be added, for a total of 2 or 4 circuits.
Sprue chuck circuit The timing of releasing a sprue can be selected by setting the timing mode.
Pitch rivise circuit The product pitch can be changed inside an end-of-arm tool.
Sprue cut circuit It is a circuit to cut a sprue by a nipper inside an end-of-arm tool. Combined use with "Gate cut inside end-of-arm tool circuit" is not applicable.
Gate cut inside end-of-arm tool circuit It is a circuit to approach a nipper blade to a gate and then cut it by the nipper inside an end-of-arm tool. Combined use with "Sprue cut circuit" is not applicable.
Vertical wrist rotation unit (detection function included) By attaching this unit in the back of an end-of-arm tool, direction of the released product can be changed.

End-of-arm tool quick attachment/
removal equipment

An end-of-arm tool can be attached or detached quickly with this device.
Chuck half-grip circuit A pressure-reducing valve is added to the product chuck circuit in order to prevent deformation of moulded products or to secure the products during sprue cutting.
Stationary-side/
movable-side selection
It is motion mode selection to switch a side of taking out products between stationary-side and movable-side.
Signal light /Signal tower It expresses the state of the robot.
External detection at ascent limit After products are taken out, this detects whether there are any products left or not, using an external limit switch at ascent limit of the robot.
Traverse end stanchion It is used when the traverse frame is extended and when very precise position accuracy for products release is required.
External nipper unit at traverse frame After taking out products whose gate should be cut, a nipper unit at the traverse limit performs gate cut.
Reinforced vertical power specification Vertical power is reinforced by changing a reduction gear or adding a balance cylinder to the vertical arm. It is effective especially with heavy work loads.
RAII-a-100~250
Wrist flip torque increase The reinforced wrist flip unit, which increases flip torque 1.4 times more, can be attached. This is good for when an end-of-arm tool is heavy or when the amount of offset from flip center is large.
All models
Special color The robot main body, access covers and NC box can be painted the color specified by customers.
8-pin metal connector linkage with stocker It is a metal connector for linking with Yushin-made stocker.
Reject circuit When a moulding machine gives the robot reject signal, the defective product is released at a different position from good products.
Initial shots discharge motion Just after auto operation is started, several shots of products are compulsorily released at a position different from that for ordinal products.
Wait on traverse If it cannot stay at a normal waiting position (for example, because of an obstacle above moulds), a waiting position can be set on a traverse axis.
High-cycle motion
Traverse and wrist flip movements are simultaneously performed in order to save cycle time of the robot.
Undercut motion Teaching points can be added 3 positions at maximum to take out the products from an under-cut mould.
Sampling motion During auto operation, products are released to a sample release position after each specified number of shots.
Dropped product detection After taking out products, the robot continues to detect the products until it releases them completely.
Take-out failure stop on ascent limit When the robot fails to take out products during auto operation, it stops immediately in at the ascent limit, and then indicates the error. (Standard specification stops the robot operation after completing one cycle operation)
Waiting for descent order ON When a downstream machine is not ready, the robot waits for the descent order to turn ON for period set up with a timer. When the signal is not input, customer can select operation mode either to release products or to indicate the error.
Production status monitor Production status can be monitored during automatic operation. The planned production number can be specified, and the take-out robot stopped automatically when production is completed.
Low air pressure detection An error sign is displayed when the air pressure drops below the specified value.
Flying cycle start The timing to output the cycle start signal to a moulding machine is adjustable.
Protective sheet for touch screen It is a cover sheet to protect the touch screen.
Standard program software It is motion software for standard specification.
Linked operation with
Y -MAPII
A communication unit and startup program are added to the take-out robot in order to carry out moulding station control (production progress, etc.) using the Y-MAP production control FA system.
Communication with moulding machine The take-out robot can communicate with a moulding machine by using a mould number etc., which leads to shorten time for mould change.
Flexible teaching It is the software allowing you to program motions of the robot. Programming can be performed with PC or the E-touch Web controller.
Vacuum suction circuit with monitor Vacuum pressure is displayed on a controller screen in real time, and pressure setting of a vacuum sensor can be done on the controller screen.
Multilingual display change function This function allows you to choose a language used on the screen. Japanese, English, German, Chinese, Dutch, Spanish, Hungarian, Thai, French, Czech, Rumanian, Polish, Slovak, Portuguese and Korean are available.
Free casing setting
250 releasing positions on a pallet can be set up freely.
