At present, the production cycle of the mainstream fast food box injection molding factory usually takes about 4.5 seconds for one mold to produce two. One mold out four in about 5 seconds. In order to achieve such a production speed, the three major configuration equipment of the fast food box factory injection molding machine, mold and manipulator requirements are very high.

In today's world, people pay more and more attention to food safety and food packaging safety. Foamed lunch boxes and blister lunch boxes are being replaced by injection-molded snack boxes. With the growth of the injection box market, the domestic fast food box injection factory is also more and more. At present, most of the projects in the fast food box factory only focus on injection molding machines and molds. Here, let's analyze another key that has been overlooked by everyone--Fast food box high speed manipulator.

At present, the mainstream fast food box injection molding factory production cycle, generally one mold out of two in.4.5About seconds; A model of four in5seconds or so. In achieving such a production speed, the three major configuration equipment of the fast food box factory injection molding machine, mold and manipulator requirements are very high, this paper on the injection molding machine and mold without comment, only analysis of fast food box high-speed manipulator.

First of all, We analyze from the application environment.The entire injection molding and take-out stacking production week for fast food box production is basically in4.5~5between seconds. According to the fast calculation, see the following table:

`yield per day`	`Monthly output`	`Annual production`
`60 seconds/4.5 seconds * 60 minutes * 24 hours = 19200 die/time`	`19200*30 days = 576000 models/time`	`576000 * December = 6912000 models/time`
`The manipulator is to reciprocate back and forth on the beam of the machine. Each back and forth about 1.2 meters`
`Daily mileage`	`Monthly mileage`	`Mileage traveled per year`
`192001.2 m 2 times = 46080 m = 46.08km`	`46080 m * 30 days = 1382400 m = 1382.4km`	`1382400 m * December = 16588800 m = 16588.8km`

That is to say, every year the robot to go16588.8Kilometers. The visible application environment has very high requirements for the fast food box high-speed manipulator, plus the requirement of service life. Not the general manipulator Kowey competent.

Secondly, we will analyze the production process of fast food box high-speed manipulator requirements.

1、Empty cycle period.

should generally be in4.5calculated on the basis of the period of seconds, plus30%of the margin, I .e.4.5/1.3=3.46within seconds. At the same time, the development of production technology should be considered,4.5The second period shall be85%calculate; then:5*85%/1.3=2.9Seconds. Therefore, the high-speed manipulator empty cycle period should be in.2.9within seconds. Basically, most brands in the market can reach.

2、In-mold occupancy time.

Injection molding machine production cycle	No manipulatorIn-mold time	When there is a manipulatorIn-mold time occupied	Actual production cycle	Impact rate
4.5Seconds	0.3Seconds (already included in4.5seconds production cycle)	Zhuhai Kowey a brand0.4Seconds	4.6Seconds	2%
		a certainBBrand0.8Seconds	5.3Seconds	15%
		a certainCBrand1Seconds	5.5Seconds	18%

Obviously,BBrand andCThe brand production cycle increases15%The above time, let the factory output less15%Above,is very unsuitable.From the analysis of the production process, it Kowey seen that the in-mold occupancy time is the key factor in selecting the fast food box high-speed manipulator.

Combined with the application environment and the production process, we can easily draw the requirements of the fast food box high-speed manipulator.

1. Shorter empty cycle period. (High Speed)

Fast food box high-speed manipulator empty cycle should be within 2.9 seconds.

2. Shorter in-mold occupancy time. (high response)

The shorter the time occupied by the fast food box manipulator, the better, and the maximum time cannot be more than 0.5 seconds.

3. Extremely high stability. Including hardware stability and software stability. (high stability)

The first is hardware stability. The following key components must meet the requirements of use, including:

Servo motor and driver: should meet the high speed, high response, strong stop performance.
Reducer: stable and mature, international famous brand.
Guide rail and slider: should have high rigidity and high wear resistance and good lubricity.
High-speed moving cables, belts, drag chains, and air pipes: they should have high resistance to disassembly and good bending strength.
Mechanical structure: reasonable design, high machining accuracy; good rigidity.

Last but not least, it is often overlooked. The stability of the software. Software includes reasonable operation software and technical solutions. Most of the software market uses Huacheng's operating system, but Huacheng only provides the basic version, because each company has different understanding of the application. Make different improvements on the base version. This requires companies to have a deep understanding of high-speed machine applications.

Technical scheme:

The first is to increase the motor power on the original ordinary manipulator. For example, the original motor used was increased from several hundred watts to 1000 watts, or the servo motor reached 1500 watts, the speed was much faster immediately. However, the consequence is that the speed of each action feels fast, and the excessive haste between actions is very smooth. The overall cycle has not improved qualitatively. The most important thing is that the irregularity of the action conversion brings a series of serious consequences such as large machine jitter, broken belt, broken air pipe, false alarm, large guide rail wear and so on. This irresponsible technical approach is totally unacceptable.

The other is a professional development program. Like Zhuhai City for the company has a strong technical team, in the fast food box industry has many years of application experience; at the same time, fully understand the characteristics and applications between different servo motor companies, different types of servo motors and drives. Only in this way can we develop a professional and technical scheme with fast cycle and excessive smooth movement conversion.

Zhuhai Koweyproduce fast food box manipulator for the company. When working, it looks not too slow and easy. The empty cycle period is only2.6Seconds, the time in the mold does not exceed0.4Seconds.
