Detection of LCD polarizing plate

LCD industry:

Polarizing plate pasting machine in the process of supplying LCD Polarizing plate, we would like to detect the last one plate to supply the following polarizing plates without stopping machine.

Challenge
Robot arm is working for supplying polarizing plates, so the space around plates can’t be used for setting sensors. Since it’s minor change of existing machine, we don’t want major change of design.

Solution Fiber Sensor
We punch a hole in the base. We set sensors to be OFF when there are more than two plates by setting threshold. On the other hand, when there is last one plate, it’s ON and outputs. Therefore, we can know time for supply.

Detecting a protruding of a test tube

Customer: Auto assembling equipment manufacturer
Machinery: Carrier device
Test tubes are chucked during transportation. A protruding of a test tube is detected because if test tubes are not properly inserted in a rack it disturbs chuck.
 
Challenge- Sensor, that detects transparent test tubes even from a long distance in the machinery, is required.
Solution: Panasonic/Sunx
Fiber Sensor  FX-411 FT-W8
Benefits:
  • Transparent object can be detected- In this application, transparent test tubes can be detected in the combination of FX-411 which has strong beam power and FT-W8
  • Long distance sensing – FX-411 has strong beam power, if used with a sharp bending fiber FT-W8 and set to U-LG mode, long distance sensing of 950mm is possible.
  • Digital dual display – FX-411 incorporates digital dual display that enables easier setting because threshold value and current value can be confirmed at the same time

Detecting a perforation on a chemical packaging paper

Customer: Packaging machinery manufacturer
Machinery: Chemical packaging machine
This is a machinery to put tablets in the packaging paper pocket and seal it separately. After perforating with a cutter, checks the perforation.
Challenge

A sensor that a perforation of the object even on a high-speed line can be detected without fail.

Solution
Panasonic/Sunx Fiber sensor FX-301-HS FT-AFM2
High-speed response – Since FX-301-HS has ultra high-speed response time, a perforation of the object even on a high-speed line can be detected.(30us response time in H-SP mode)
Wide Range – Since FT-AFM2 has a wide sensing range, even a meandering sheet or a misaligned perforation can be detected.

Compact Head- Since FT-AFM2 is a compact head with W5 x H15 x D15mm, it saves space

Detection of Frozen Croquette on the White Conveyor

Challenge
It is necessary to set up conventional fiber sensors with close distance, and the maintenance for a conveyor was hard when detecting white object on a white conveyor.

Solution
Amplifier – Digital Fiber Sensor FX-301
Fiber – Reflective type flexible unit FD-P80

Benefits

  • With long detecting distance of 100mm, the maintenance for a conveyor has become easy
  • Hysteresis adjustment allows you to detect the slight
    height difference even when the background is white.
  • R4 fiber can be bent like an electric wire to save space when it is installed.

Detecting a mark tape on the transparent film

Customer:
Food packaging Manufacturer
Machinery:
Packaging film manufacturing equipment detects the red mark tape where the food packaging films glued together for home use by a sensor.

Challenge
Customer used competitors sensor , but false detection occurred due to the transparent film.

Solution
Panasonic/Sunx Photoelectric Sensor
FX-305 has two output channels. Alarm output mode in PRO mode (PRO6) enables alarm output for light amount drops and signal output for the mark tape detection.

Detecting presence or absence of shrink labels

Previous Method
Customer would like to detect the presence or absence of transparent films (shrink labels). They detect only transparent films by sensors because the films cover bottles loosely. The bottles stop at the predetermined spot on a line, and the bottles with films can be detected by shielding. After confirming the presence of shrink labels, they heat the bottles and adhere labels to the bottles.

Problem
Detecting films stably is difficult because they are transparent. In addition, setting sensors in a narrow space is hard.

Solution
Panasonic/Sunx Fiber sensor FX-301 FD-T40 RF-210
You can confirm output state of sensors for detecting labels at the moment that sensors for synchronizing detect bottles. And process of attaching labels to bottles can be confirmed because the labels shield sensors.

Confirmation of presence or absence of pellets

Customer:
Resin products manufacturers
Machinery:  Resin molding Machine

Application:
Confirmation of presence or absence of pellets
Pellets, which are material of resin products, are carried by air to a resin molding machine in this application. The pellets inside a transparent pipe is confirmed.

Problem:
Some malfunctions are caused by dregs of pallets, which are left by static electricity, inside a transparent pipe.

 Benefit
FT-A8 can stably confirm the remaining amount of pallets without being fully obstructed by dregs of pallets, because FT-A8 is the wide beam type whose detection width is 11 mm.

Rubber molding removal confirmation

Laser sensors used to detect if rubber cap is stuck in mold

If a molded rubber cap is left in a die, it brings die breakage so rubber molding removal is required to be securely confirmed. Machine is stopped if even one rubber cap is not present on a holder after a rubber cap is transported from die to holder. Even a holder (background) and a rubber cap are close together, FGS function brings stable detection.
