Improve bookbinding machine productivity

There are generally three main reasons for the waste of time on the gutters: equipment failures, pre-start preparation and machine adjustments, and improper materials. To improve the production efficiency of gutters need to start from the following aspects.

maintenance

Maintenance is a cultural quality. Simply evaluating how good or bad the operation is based on the amount of output will result in a habit of not paying attention to maintenance. If there is a strong sense of quality, when the problem is encountered, the machine will be turned off and the machine will be adjusted. Removing the old knife from the machine is tiring, but it is worth the time.

In order to extend the tool change cycle, some installed subscribers use a low temperature tempering method to cool the knife with liquid nitrogen to a temperature below minus 300 degrees Fahrenheit for a period of time. According to reports, if processed well, the low-temperature tempering method can change the micro-structure of the knife and increase the strength of the knife. The cost of a low temperature tempering process is based on the weight of the knife and the number of knives to be processed. For example, at the National Low Temperature Lab, the base unit price is $9 per pound.

Reduce the preparation time before starting up

In order to reduce the preparation time before start-up, it was advocated to use a one-minute mold change method. This method was originally developed from the automotive industry. It divided the entire task into two types, internal and external. Internal tasks can only be performed during downtime. External tasks can be performed while the machine is running. Preparing for preparatory work is one way to reduce internal tasks. Is it correct to apply all the tools and materials necessary for checking the preparation before starting up? If yes, are they layered and easy to get? Are all tools and materials working under normal conditions? Recording equipment adjustments and operating conditions helps identify areas for improvement.

The new generation of bookbinding machines are much easier to adjust, and most of them use programmable logic controllers (PLCs) to control preparation before starting up, display production status, and perform fault diagnosis.

Miller Mavni's Prima saddle stitcher has an automatic, computer-controlled pre-boot preparation system that allows for direct adjustment and timing adjustments. The automatic adjustment is performed by a PC controller. Repeatable settings allow working data to be stored on disk for later recall. While the current job is still in progress, the next job can be programmed. According to statistics, the entire preparation before starting up, including data input, can be completed in 10-15 minutes.

Smooth paper feeding

Some experts believe that the folding and delivery of the folded paper to the collation desk accounted for 80% of the saddle stitching process. Some of the problems that may occur during the loading of book posts, such as paper skew, curling, tearing, lack of compaction in the folding of the signature, non-stiffness, misplaced signatures, etc., all of these problems will cause paper feeding. It becomes very difficult and the speed of the stapler is greatly slowed down.

The signature recognition device facilitates smooth paper feeding. This device has a sensor mounted inside the paper feeder and can perform optical scanning of signatures. It can measure the specified signature and compare the measured value with a preset value that was automatically stored in the device at the beginning of production. Deviations of the signature are detected and Removed from the production line.

The Best OsakoSystem 368, a mid-production stapler recently introduced by Best Graphics, features a central console for monitoring speed, counters, fault displays, and jam alarms.

Rosback recently introduced the Lynx line 724 saddle stitcher with a design capacity of 5O0-3200O per day. It features a 4-fold vertical feeder unit, each station can hold 9in (22.86crn) paper stock and can be used to start the fashion paper.

Heidelberg's Stitchmaster 270 medium-volume saddle stitching machine can be set up in book or horizontal. The vertical structure can hold more signatures, thus reducing the number of paper loading. This feature can also reduce the operator's fatigue, they can determine whether to make it established or horizontal according to the specific circumstances of each batch of live.

Full service Mailers installed a Fenimore-Vijuk 920 Sidewinder with nine signature posts, which can be used for the bookbinding production of short-run booklets. Sidewinder uses a vertical rotary transfer device. Its signature hopper system allows the user to change the position of each affixing station according to the size of the live batch. Each hopper can be adjusted to accommodate various thicknesses of paper. Materials or signatures. The Sidewinder is rated at 5,000 volumes per hour, which is still good if it is open to 250O0 volumes per hour.

In 1999, Vijuk launched the Purlix 321-T saddle stitching machine with a rated speed of 10 000 volumes per hour. It features top loading and bottom feeding so that it can be continuously produced.

Increase supporting equipment

The increase in the efficiency of the printing shop is bound to put pressure on the binding. In order to speed up business turnover, configuring suitable, new and efficient binding machines or adding ancillary equipment such as inkjet devices or mailing tables behind the binding machines can satisfy customers' various needs.

Time-saving auxiliary equipment

People now have an automatic counting stacker behind the binding machine. Many people have installed continuous paper feeders and book binders, but the binding of book blocks should be done in the press shop. On the edge of the paper next to the three-sided cutters, an automatic system can be designed to suck them into a stack of waste paper in a continuous air stream, where they can be packaged and transported away. Stapling workshops often have a large number of calendars to be bound. If you can finish saddle stitching and punching in one line, you will save a lot of time.

Auxiliary devices that can save time include strapping machines, shrink packers, and various counting and weighing devices.

Willing to spend time training

It is necessary to train operators in a planned manner, especially when installing new machines, and must arrange as much time as possible for training. Maintenance personnel are also required to participate in the training because the machine can only be repaired if they are familiar with the operation of the machine.

Finally, keep in mind that "fast" is not necessarily good. Only by handing out neat and clean products, can we recover the money. The customer doesn't care how fast your machine turns.
