The models of H series and G series synchronize operation with press machine by a private rotary encoder (rotation sensor). Other models do so by two synchronizing signal. The products which are syncronized by a rotary encoder cannot cope with servo press machine.

Options

We offer many options. They can be used in combination according to the situation. Please refer to the price list page for the compatibility between each product and options.

Remote Box: RC6A

Remote Box: RC6A

It enables operation of one cycle, jog, roll open/close, and Sync Release from a location away from the main controller. Cable length can be selected from 3m or 5m. The speed of one cycle by this unit is only the speed during jog. For safety, operation from the main controller is prohibited when operating with RC6A. Also, operation with RC6A is not possible during setting for synchronized operation with the press machine.

Feed Direction Switch : DS6

Feed Direction Switch : DS6

It enables switching of the roll rotation direction. Both feeding and pulling of materials are possible. An additional material break sensor can be connected, and it is possible to switch which sensor is enabled according to settings. This unit is installed by stacking on top of the main controller.

Data Bank : MP6

Data Bank : MP6

It can store up to 99 sets of settings such as feed length, feed angle, and release conditions. This eliminates the need to re-enter feed conditions every time the die is changed, and they can be recalled. Also, by linking some of the 99 sets, program operation similar to conventional multi-stage feed units is possible. The maximum number of feeds per stage is 99. When combined with feed direction switch DS6, feed direction reversal is also possible. This unit is installed by stacking on top of the main controller.

Feed Complete Output : FF6

Feed Complete Output : FF6

It outputs a signal when material feeding is completed. It can also be used when interlocking with other peripheral equipment is required. Output enable/disable can be selected by operation switch and external input. When combined with feed-in-progress output BS6, operation equivalent to the conventional Feed Master option (alternating operation with press) is possible. This unit is installed by stacking on top of the main controller.

Feed-in-Progress Output : BS6

Feed-in-Progress Output : BS6

It outputs a signal when feeding material. It can also be used when interlocking with other peripheral equipment is required. When combined with feed complete output FF6, alternating operation with press equivalent to the conventional Feed Master option is possible. This unit is installed by stacking on top of the main controller.

Feed Condition Measurement : TC6

Feed Condition Measurement : TC6

This is an option that automatically inputs the feed angle of our feeder and the press operating speed setting value. Please set the feed signal on the press side in advance. Then, by operating the press in trial mode, the feed signal is measured and the feed angle "Feed Angle" and press operating speed "spm" of our controller are automatically calculated (patent pending). Recommended when operating the press in pendulum or irregular motion, where it is difficult to set by numerical conversion. This unit is installed by stacking on top of the main controller.

Optical Material Break Sensor

Optical Material Break Sensor

An optical sensor that detects material breakage. The sensor sensitivity can be adjusted according to the environment. It can be installed on all models, but for T series, it can only be used in coil mode and single mode. Installation method and position differ by model. There is no compatibility between products.

Pull Specification

Image coming soon

The feeder is installed on the downstream side of press processing and pulls the material. Please select this when you do not want to leave marks such as roll marks on the product, or when the material is thin and easily warped.

Controller Offset

Controller Offset

The controller of models with the controller mounted on the top center of the feeder (J and R series except J06) is shifted and installed to the side away from the press machine. Effective when the feeder interferes with the press, etc. when installing.

Swing Cover

Swing Cover

A cover that covers the roll section of the feeder. Helps improve safety and protect materials.

Urethane Roll

Urethane Roll

A roll with urethane resin wrapped around an iron core. Effective for preventing pressure marks on materials that might be flattened by metal rolls and improving feed accuracy for slippery materials. However, chemical resistance and durability are inferior to standard rolls. Cannot be used with H series and A-A series due to their small roll release stroke.

Silicon Roll

Silicon Roll

A roll with silicon resin wrapped around an iron core. Compared to urethane rolls, it has superior non-adhesiveness, heat resistance, and chemical resistance, making it suitable for transporting film materials, adhesive tapes, and printed materials. However, its abrasion resistance is inferior to urethane rolls, and it is more prone to slipping. Similar to urethane rolls, cannot be used with H series and A-A series due to their small roll release stroke.

BBC Roll

BBC Roll

A roll that has undergone blast and bluing treatments. Features a high friction coefficient on its contact surface with materials, enabling the transport of materials with minimal slippage. A drawback is that materials are prone to getting scratched. For delicate materials, an option for a separate roll that allows the central part of the material to be avoided is recommended.

Central Clamp Roll

Central Clamp Roll

An option specifically for the A-A series. By using a central clamp roll, the minimum material width that can be handled is reduced by up to 50mm compared to standard rolls. A caution is given that the transport capacity will change, and further details are referred to "this document".

Separate Roll

Separate Roll

Rolls can be installed separately. Can be adjusted according to material width.

Apron Roll

Apron Roll

An apron-shaped roll. Used to stabilize material feeding.

Slide Plate

Slide Plate

A slide plate that assists in material feeding. Can be selected according to material type and thickness.
