1. Introduce
1.1 Outline
The traditional glove air leakage detection manually uses inflatable lights individually and then hanging water sampling. Manual inflatable light inspection, high labor intensity, and high technical requirements for the operator, a skilled inspection of a glove needs to take 3 seconds to 7 seconds, and the inspection quality is easily affected by the operator’s reasons. Finished products hanging water sampling not only use many water resources but must also be dried again after inspection. Hanging water workshops generally cover a large area for enterprises to invest in high costs.
Glove air leakage detection equipment came into being through high-precision sensors to detect glove leakage, high detection accuracy, stable quality, and fast detection speed. For batch testing, a glove spends about 1 second; for online sampling, the detection accuracy requirements are very high, so a glove spends about 2 seconds.
1.2 Function Introduction
The glove air leakage detection machine completes the following functions:
(1) Head rotary start-stop control, speed adjustment;
(2) Glove pre-blow shaping, clamping, and inflation;
(3) Glove air leakage detection;
(4) Qualified gloves off;
(5) Waste rejecting of defective gloves. Special tips:
★Before operating this equipment, read the manual carefully first. Otherwise, it will damage the personnel and equipment.
★ Compressed air is the main power of the equipment action. You need to ensure that the compressed air pressure is not less than 0.6MPa and that no water, oil, or dust will affect the detection effect, shorten the service life of the components, and even damage the equipment.
2. Introduction to the interface
2.1 Main interface
The main interface of the system is shown in the above figure and contains the following:
(1) Start-up conditions area: all lights are on, you can start the equipment; otherwise, you need
to check the reasons for not lit;
(2) equipment operation area: each shift needs to set the line number corresponding to the glove variety, and according to the current shift to update the batch code setting (generally the year, month, and day + serial number (must be 10- digit number, otherwise the code is invalid, such as 2019010101);
(3) Running operation area: ‘rotary control’ to start and stop the head rotary; ‘speed +’ and ‘speed -’ buttons can be adjusted to the production speed, the minimum of 3 m / min, the maximum of 14 m / min. (4) Production data area: It displays the production data of the machine;
(4) Production data area: It displays production batch, total number of products, pass rate, production speed, power-on time and production time, etc. (it will be changed according to the actual status);
(5) Interface switching area: switching between interfaces.
2.2. Setting Interface
The function setting interface is shown in the figure above and contains the
following:
A. Automatic setting:
(1) ‘Manual release’: At an emergency stop, you can manually open the holding brake. (Note: the emergency stop button is not shot down; you can not release the holding brake!)
(2) ‘Clamping valid’ enables the clamping function of the clamp; if you click to change to ‘Clamping invalid,’ the device will no longer control the clamping of the clamp;
(3) ‘Open valid’ enables the clamp opening function; if you click to change it to Open invalid,’ the device will no longer control the clamp opening;
(4) When a new batch starts to be inspected, you must make sure that the text on the re-inspection button is ‘Re-inspection’ instead of ‘Re-inspection in progress.’ After the inspection, when the same batch of products is re-inspected for rejects, you need to press the re-inspection button so that the text on the re-inspection button changes to ‘Re-inspection in progress.’ The text on the re-inspection button will
change to ‘Re-inspection in progress.’ (Improper operation may cause counting errors and inaccurate test results, so check whether this setting is correct before you start using the machine;)
B. Password area setting:
Input password ’ is used for parameter setting by employees with operation authority.
(1) ‘Synchronised value is used to calibrate the encoder value; Actual position pulse: the device’s current reciprocating mechanism and belt position value.
(2) Upper and lower position pulses: set the upper and lower alarm limits. If the actual position pulses exceed the upper and lower limits, the equipment will alarm and stop so as to prevent the equipment from being damaged due to faults such as belt jumping teeth or breaking. Requirements: The upper and lower limits are set according to the actual running condition; the upper limit position pulse value is about 60 times larger than the actual position pulse value; the lower limit position pulse value is about 60 times smaller than the actual position pulse value; the spacing should not be too large to prevent the equipment from losing its protective effect.
(3) If the alarm interface prompts that the head number is wrong, rotate the device idly for 1 turn to initialize the detection head number automatically;
(4) Click on the ‘password box’ to pop up the keyboard box, enter the password (1111), and you can clear the cylinder count. The guide rod cylinder is equipped with an action limit alarm; when it reaches the upper limit of action, the equipment alarm prompts the replacement of the guide rod cylinder, and after the replacement is
completed, the counting value will be cleared, and the counting will be restarted;
(5) Automatic debugging button, when switching the debugging function, can be used to test whether the cylinder works normally;
C.View and set jump
(1) ‘View Production Data ’to view production statistics, which can be copied to a computer, as shown in the figure below:
(2) Click on the ‘password box ’ pop-up keyboard box, enter the password (123), and you can set the test level. According to the different batches of gloves, the elasticity property of gloves may change slightly, resulting in differences in the test results, which will be corrected according to the sampling situation of gloves.
(3) blowing time settings, each line corresponds to a different variety of gloves, different varieties of gloves of different sizes. Hence, the blowing time for gloves is different, and the ‘pre-blow time ’ detection of small gloves can be properly corrected and skewed to improve the detection accuracy. Click on the ‘password box ’ to pop up the keyboard box, and enter the password (123) to set the pre-blowing and blowing pressure. By setting the pre-blowing time, you can control the amount of glove adjustment; if the adjustment amount is too small, the glove can not be corrected; if the adjustment amount is too large, the glove will slide to the bottom of the seal, affecting the test results, the pre-blowing time should be set according to the actual needs. The pre-blowing time should be set according to actual needs:
2.3 Monitoring Data Interface
The ‘Inspection Data’screen is shown above and contains the following:
The ‘Test Data’screen contains 36 groups of head test values and
status; The ‘Alarm Indication’light indicates that this group of heads
has failed; The color of the ‘Test indicates the corresponding
status:
Green: Pass;
Yellow: suspected product;
Red: unqualified or suspected product.
Suspected products need to be tested again. When detecting suspected products, you need to click the ‘Re-inspection ’ button in ‘Function Setting ’, and ‘Reinspection’ on the re-inspection button will change to ‘Re-inspection in progress ’ before re-inspection can be carried out. ‘At this time, if the product is qualified, the number of defective products will be reduced by 1, the number of qualified products will be increased by 1, and the total number of products will not be changed.
2.4 Parameter setting screen
The ‘Parameter Setting ’ interface shows whether the machine head is enabled, and the setting can be switched by clicking the button. Under the operation condition, after the head fails to pass three times in a row, it will automatically switch to the ‘Invalid ’ mode (the button lights up, and the corresponding head stops moving). You need to investigate the problem manually. The corresponding button will be extinguished to reactivate the head.
2.5 Alarm screen
The alarm interface, shown above, displays the cause of the fault in the event of a machine malfunction to help troubleshoot the equipment.
2.6 Help screen
The help interface, as shown above, suggests equipment operation and precautions, so please read it carefully and be safe and forewarned to protect yourself from damage.
3. Operating Procedures
3.1 Normal operation procedure of the equipment
(1) In the normal production process, the operator should put the gloves on the fixture as flat and even as possible, and the wrist opening of the gloves should be more than about 10mm above the sealing ring, with no wrinkles at the wrist opening, and the height of the wrist opening is uniform, and there should not be any skewing severe phenomenon, or it will lead to inaccurate test results;
(2) Ensure that the compressed gas meets the ‘three noes’: no water, oil, or dust. Otherwise, it will cause damage to all pneumatic components of the equipment, equipment, airtightness decline, affecting the life of the equipment, or even cause damage to the equipment.
(3) Switch on the device’s power and confirm the following: The ‘Function Setting ’ screen is set to ‘Initial Inspection’; The start
conditions in the ‘Main Screen ’ are all lit up. The production data in the ‘main interface is cleared, and the batch is set.
(4) The main screen ‘Acceleration‘ and ‘Deceleration’ set the running speed (which can also be adjusted after startup).
(5) Click on ‘Slewing Control’in the ‘Main Interface’or press the ‘Start ’button in the operation box, the machine head will start slewing. (6) Press the left ‘test ’ button, and the clamp starts to move; press it again, and the clamp stops moving. (Note: to prolong the life of the equipment and protect the equipment from damage, the test button should be pressed when the speed of the vehicle is lower than 5m/min, and then slowly increase the speed, and it is strictly prohibited to press the button when the speed of the vehicle is greater than 5m/min). (It is strictly forbidden to press the ‘test’ button when the vehicle speed is more incredible than 5m/min!)
(7) The operator opens the glove leather band, sets it on the machine head, starts the automatic inspection, sets the glove position between the two buttons, and prohibits the glove from outside the glove work area set the glove, to prevent the fingers from being pinched;
(8) After the gloves are inspected, the judgment will be as follows: non-conforming products will be taken off the inferior products collection box. Qualified products will be taken off the finished product collection box
(9) After the inspection of this batch of products is completed, if it is necessary to carry out a re-inspection of the rejected products, switch to the interface of‘Main Interface’ and click the ‘Re-inspection button in this interface, the text on the ‘Re-inspection button will change to ‘Re-inspection in progress,’ and then the re-inspection will start; then the re-inspection will be carried out. The text on the ‘Re-inspection button will change to ‘Re-inspection in progress,’ and then the re-inspection will start;
(10) After completing all the inspection tasks, press the ‘Inspection’ button once to stop the clamp action; then press the ‘Review’ button so that the text on the review button shows ‘Review,’ then click the ‘Stop’ button on the main interface or press the ‘Stop’ button on the operation box, the machine head stops rotating and completes the shutdown. Then press the button ‘In Review’ so that the text on the preview button shows ‘Review’ to release the state of review, and then click the button of‘Stop’ in the main interface or press the button ‘Stop’ in the operation box to stop the machine head from rotating and complete the shutdown.
(11) Switch off the power;
(12) The operator recovers the qualified gloves and disposes of the unqualified gloves to complete the production.
3.2 Precaution
(1) The finished product collection box and the waste product collection box should be placed high, about 5 cm from the basket mouth to the lower edge of the fixture. The distance from the basket mouth to the lower edge of the fixture should not be too large; otherwise, it will lead to confusion when the finished product and the waste product are taken off the fixture.
(2) During the production process, the number of gloves in the collection drawer of the finished products should be checked frequently. When the drawer is full, the gloves should be cleared out immediately to avoid confusion between the finished and scrap gloves.
(3) To ensure the normal operation of the equipment and the accuracy of the test results, the pressure of the pneumatic triplex corresponding to the airline with more stringent pressure requirements (orange 16mm air tube in the air box) should be adjusted between 0.55~0.6MPa, and the pressure of the airline with relatively stringent pressure requirements (blue 16mm air tube in the air box) should be adjusted at
about 0.5MPa, and the pressures of the two airlines should not be too low or too high.
