Abstract: The automatic heat shrinkable packaging machine is a highly automated equipment. Labor cost has an important economic significance, and the diagnosis of faults is also very important.
“
Automated operations in the packaging industry are changing the way the packaging process works and the processing methods of packaging containers and materials. The automatic control packaging system designed and installed has a very obvious effect in terms of improving product quality and production efficiency, or eliminating processing errors and reducing labor intensity. Fully automatic shrink packaging machine is a highly automated equipment. The automatic control of the packaging system can greatly improve production efficiency and product quality, especially for food, beverage, pharmaceutical, electronics and other industries. . The application of shrink film packaging machine can greatly reduce the material and labor costs of medium box packaging, which has important economic significance.
1 The main components and working principle of REHOW S-600 packaging machine
A complete automation structure scheme consists of many components, among which end-arm operation tools, material conveying devices and identification and verification systems are the main components. Its working principle is as follows:
It is a tool that uses the device connected to the end of the manipulator to move from one position to another. End-of-arm tooling, the end effector. It is a part used to grasp the product, orientate the movement and feel the performance parameters. Their structural schemes can range from a single type of vacuum sleeve to a series of vacuum sleeves or an arrangement of clamping jaws. In packaging applications, end effectors are usually designed as ready-to-use vacuum sleeves, clamping jaws, or a combination of both.
1.2 Material conveying device
Material conveying and handling devices are certain types of equipment that are required for automatic movement during the transmission and manufacturing process for the transportation, storage, and control of products. These include power transmission belts, monorail cranes, automated guided vehicles and manipulators. A typical material handling and handling system includes: belt type input conveyor, labeling machinery, bar code reader, automatic device and output conveyor. A graphical user interface provides an easy-to-operate platform for delineating pallet stacking patterns. According to the number of workpieces produced under control, the manipulator grabs, orientates and places (stacks) each packaging container (case, box, barrel, can, etc.) on the correct pallet position. in the packaging process. The following factors need to be considered in the delivery processing of materials: product shape, weight and material properties; speed, distance and direction of product movement during transportation, packaging and loading; Form the mobility of components.
1.3 Identification and Verification System
The ability to identify, authenticate and precisely track products has become an integral part of the entire packaging system. Identification methods can use traditional barcodes to radio frequency (RF) sensors, which are able to track pallets or whole products. A typical visual barcode detection capability can confirm that each barcode corresponds to each product, so barcode scanners and video identification systems record and verify product labels to ensure the integrity of the identification. Online barcode printing and verification is also necessary. Vision technology, which can provide effective and reliable means to ensure product quality, can be used in many occasions of packaging, such as product detection and orientation, filling level and counting, optical labeling, text recognition, labeling text verification, labeling, etc. Paste records and verification of all text and graphics (leaving the production line), etc. The bar code system identifies the product through the product type, date and area code, and the printing process called prepress or inline by the manufacturer.

2 Common Fault Diagnosis and Elimination
This failure is often caused by the packaging material having joints and excessively large burrs; the paper feed motor circuit failure or poor contact of the circuit; the paper feed proximity switch is damaged, etc.
Method of exclusion:
(1) Remove unqualified packaging materials.
(2) Check the paper feed motor circuit.
(3) Replace the proximity switch.
This failure is often caused by uneven inner layer of packaging material; uneven sealing pressure; low sealing temperature, etc.
Method of exclusion:
(1) Remove unqualified packaging materials.
(2) Adjust the sealing pressure.
(3) Increase the heat sealing temperature.
This failure is often caused by the wrong position of the heat sealer body.
Remedy: Readjust the position of the heat sealer body.
2.4 The position of the bag cutting is not correct and the deviation from the middle of the color mark is too large. Reason: The position of the photoelectric switch (electric eye) is incorrect.
Troubleshooting method: Readjust the position of the photoelectric switch (electric eye).
2.5 Color mark positioning and photoelectric tracking compensation out of control
This failure is often caused by seams and burrs in the packaging material; there are sundries in the former. The paper is not moving smoothly; the packaging material escapes from the paper guide plate of the photoelectric switch (electric eye); the light spot of the photoelectric switch (electric eye) deviates from the color mark; the sensitivity of the photoelectric switch is poor. Caused by wrong use of light and shade.
Method of exclusion:
(1) Remove unqualified packaging materials.
(2) Clean the former to make the paper go smoothly.
(3) Insert the packaging material into the paper guide.
(4) Adjust the left and right positions of the paper guide plate so that the light spot is in the middle of the color mark.
(5) Replace the photoelectric switch, and choose the light and dark dynamic switch correctly.
2.6 When the color mark tracking is not performed (that is, the photoelectric switch is turned off), the bag length error is large
This failure is often caused by inappropriate bag length setting: the pattern of the roller is worn flat, resulting in reduced friction; the pressure of the roller is small, etc.
Method of exclusion:
(1) Increase the set value of the bag length so that the actual bag length is equal to or slightly greater than the standard length of the color code.
(2) Replace the rollers.
(3) Increase the roller pressure.
This failure is often caused by too little pressure between the two cutting knives; blunt cutting edge and so on.
Troubleshooting method: (1) Adjust the pressure between the cutters. (2) Grind or replace the cutter.
2.8 The paper feed motor does not rotate or rotates continuously
This failure is often caused by the jamming of the paper feed control lever; damage to the paper feed proximity switch; damage to the starting capacitor; broken fuse, etc.
Method of exclusion:
(1) Solve the cause of the stuck.
(2) Replace the paper feed proximity switch.
(3) Replace the starting capacitor.
(4) Replace the fuse.
This failure is often caused by: damage to the heating tube; line failure; broken fuse; damage to the temperature regulator; open circuit of the thermocouple, etc.
Method of exclusion:
(1) Replace the heating tube.
(2) Check the wiring.
(3) Replace the fuse.
(4) Replace the temperature regulator.
(5) Replace the thermocouple.
2.10 Do not pull the bag (the motor for pulling the bag does not run)
This failure is often caused by line failure; damage to the bag proximity switch; failure of the automatic packaging machine controller; failure of the stepper motor driver, etc.
Method of exclusion:
(1) Check the circuit and troubleshoot.
(2) Replace the pull bag proximity switch.
(3) Replace the automatic packaging machine controller.
(4) Replace the stepper motor driver.
