A method to solve the failure of the paging machine

Automatic equipment pager is to replace people to complete this work, pager can reduce slight labor, improve work efficiency, pager will enter another office or new products after the small printing industry is the integration of digital printing, in case of double, missing pages will automatically stop reporting errors. The equipment can be used alone, also can be used with offset printing equipment, greatly improving the speed and quality of finishing, is the first choice for large and medium-sized printing enterprises.

Faults often occur in the paging machine:

The v-3-1/4B valve of the machine fails page 1: This kind of failure is mainly caused by the paper scraps and dust entering the valve sleeve, and the air intake is reduced, which is not smooth. In this case, as long as the deposit of the cleaning machine is ok.

But the cause of the damage is not necessarily the blockage of the inspiration, it may be removed, improper method, resulting in the damage of the valve cover, in promoting open source and throttling the valve bought today, to spend thousands of yuan, pay attention to. Correct method: Remove the valve from the working position of the machine, one end of the jaw side of the body, nail in front of the mouth, the purpose of doing so is to increase the contact area of the screw, prevent the bursting of the valve sleeve, and help to eliminate the clip ring.

This is mainly in the tooth tension design machine is too large, the spring will be in its teeth and hanging spring column friction, time has been a few spring sleeve will wear, if not arrange the parts of the machine in time to change will seriously affect the screw must be replaced with piezoelectric pieces will be taken out.

There are several reasons for this. First, the air valve is blocked by tiny substances. In production, there may be scraps of paper and dust flying into the air valve, which increases with the accumulation of time and finally leads to a serious reduction in the air intake. In this case, after cleaning, the dust should be checked regularly in the future production.

The second reason is that the gas valve sleeve is damaged, which may be caused by improper installation and disassembly. The cost of the gas valve is high and the cost is also high, so in order to save money. Be careful when removing and installing air valves.

The correct way to remove the air valve is as follows: the first step removed the end of the air valve body on the side of the clamp, the other end against the front mouth, mainly in order to protect the valve cover from damage.

2. The tension spring of the pager in its teeth is out of order. The main reason for this is that at the beginning of the design of the machine, the tension spring in its teeth was too large, and the protective cover of the tension spring was worn out after constant friction between the tension spring and the spring column. Further damage to other internals. Therefore, a batch of new ones can be processed according to the protective sleeve specification of the device for regular replacement.

To sum up, it can be seen that the pager is easily damaged in the production process, so it is necessary to do a good job in the daily maintenance of the pager, in order to extend the service life of the pager and save production cost.

Do you know the factors that affect the production efficiency of pager?

The production efficiency of the pager not only depends on its page-matching speed, but also depends on the number of the bookbucket configured on the page-matching machine, the production quality of book posts, the size of the folio and the number of book posts with inserts.

1. Number of books. With the increase of the number of book bucket and the number of each matching, in a certain period of time, the possibility of shutdown and shutdown times will increase, thus reducing the reliability and utilization coefficient of the machine. According to the relevant information, when matching book bucket increased from 12 to 24, due to the book post delivery is not in place, there will be two book at the same time hold or other some fault, in matching medium book post, the use coefficient of the page machine decreased from 0.833 to 0.776. The total time taken to troubleshoot the shutdown increased from 16.9% to 22.4% compared to the time taken to complete the process. When the number of matching increases, the operator has no time to troubleshoot, in order to ensure the utilization factor of the machine, must increase the auxiliary operator.

2. Quality of book posts. With the page, due to the book post extrusion, paste is not standard, or warp and damage and other quality reasons often stop fault, thus reducing the use of the machine coefficient and the production efficiency of each shift.

3. Folio. As a result of the quality of the book, when the preparation of a large block, the possibility of downtime increased. Therefore, with the increase of page dispenser, the production efficiency of each shift decreases. According to relevant data, when the number of bookends increased from 12 to 24, the loss of productivity per shift increased from 4.7% to 8.5%, compared with the loss of medium bookends. If the number of pages is increased to 30, the loss of productivity per shift rises to 8.9%.

4. Number of book posts with inserts. The book post in the sticking page, the pages are easy to be adhesion, the book post deformation, resulting in the thickness of the book block is not the same, resulting in the number of stops increased.
