Velocidad Komori L626

Saludos.
Tenemos problemas con la impresión debido a la velocidad de la máquina.
No tengo manuales eléctricos. Me pregunto si alguno sabe como regular las velocidades de trabajo. Adjunto tarjetas electrónicas de la máquina
Gracias de antemano

 

Hi sir:
Go to the start up speed Screen and follow this:
This screen is used to select the start-up speed during automatic paper feeding (PRODUCT) start or test printing.
However, note that when the feeder and pump have been turned on by manual operations, SLOW start is
performed.
[SLOW]: Sheet feed starts from SLOW speed, and then increases to FAST speed after the last cylinder is
engaged.
[FAST 1]: Sheet feed starts from SLOW speed, increases to FAST speed (8000 rph), and then changes to the
speed set by the PRESS SPEED ADJUSTMENT dial after the last cylinder is engaged.
[FAST 2]: Sheet feed starts from SLOW speed, increases to FAST speed (12000 rph), and then changes to the
speed set by the PRESS SPEED ADJUSTMENT dial after the last cylinder is engaged.
[FAST] is a function used to aim for early stabilization of initial printing. The guideline for using this is a paper
thickness of 0.3 mm or less. However, [SLOW] should be selected even when using a paper thickness of 0.3
mm or less if the paper condition is poor or if sheet feed does not stabilize.
Selectable speeds vary depending on the models and the specifications.
The maximum printing speed is 8000 rph for [FAST 1], and 12000 rph for [FAST 2].

 

Thanks for your response.
This machine is a little old, it doesn't have screens. The only thing I have are those electronic cards that are attached in the photos

 

ok sir

1) I don't know if your engine has a sensor or not.

2) If you do not have a sensor, check the engine brake and the air gap must be 0.6mm to activate the limit switch, located where the engine brake is mounted. . Clean its parts well.

If it has a sensor or camless motor, the matter is complicated because several steps have to be done, which is difficult to describe, since there are photos, etc.

 

Okay, thank you. I will review these points.

 

Ok, be very careful.

 

Cleaned the engine brake. However, we continue with the ruling.
I will explain a little more:
The machine rotates well by forward pulses. The next gear works fine, normal slow, but the second gear increases and immediately drops to the first gear. And the third speed works well with respect to the speed set on the panel.

We have the problem with the second speed, when we lower it to minimum the print comes out with spots and we are losing a lot of material.

I hope you understand me.

 

The problem may be if it has a servomotor, it is damaged or poorly adjusted.
It will be good if you take a photo of the engine.
Bendiciones.

 

Hello Isaac,
Your Attached Photos Shows, your machine is 1991-94 Year. that means your machine have DC motor.

where can i understand there are three modes of speed, 1st Slower(similar to Inching Speed), 2nd Slow(speed between 2000-3000 IMP/Hr), 3rd fast Preset speed(which you can set from potentiometer on delivery panel).

now please explain which mode you are facing problem.

and if possible please attach main motor photo (just to see is there are two diffrent motor or single motor).

 

Hi Sir :

Did you follow my steps?

Let me know.

 

Good morning! I followed the recommended steps, I found no sensors. However, the workers have been working like this without any major problems.

 

The speed in inches works well. 3rd speed adjusts well and works well. The problem is in the second gear. When the paper feed starts, the speed is lowered until reaching the last printing unit, but it is lowered a lot.
The failure is basically in this input process until reaching the last printing unit

 

Oh Ok, now i got it properly.
Your speed is getting low while you start the Production and once it LAst unit impression got on Machine switch to high speed.

for this low speed there is a potentiometer near Drive in main Panel, you just have to Adjust that and you problem get solved.

Allow me a Day will let you know the Number of it, and location
