Fig. 3 is that Fig. 1 has made to omit, simplify the stereoscopic schematic diagram of processing.

Thirdly.

As shown in Figure 1, tested gas flushing pouch, moves from left to right under the drive of conveyer belt 2.Gas flushing pouch exists At A point in Fig. 1, push belt 12 above is touched, then under the clamping of upper and lower two belts, continues to move right；Together When, the gas flushing pouch of bulging under the downward pressure of push belt 12, generate upward reaction force in turn so that push belt 12 receive upward thrust, therefore, rotate frame 13 and its rotation pushing equipment rotates counterclockwise together, or claim For swing.

Press mechanism applies downward pressure to rotation frame 13；Rotate frame 13 to drive roll 9, passive roller 10, with And transition roller 11 applies downward pressure, finally results in push belt 12 and downward pressure occurs.

If being reference with the earth, a suitable checkpoint is determined on rotation frame 13, than B as in Figure 1 and Figure 2 Point, compares Fig. 1 and Fig. 2, and height dimension H2 is greater than height dimension H1.If being not reference with the earth, it is changed to conjunction a certain in rack Suitable fixed point is reference, also it can be concluded that the conclusion of similarity.

In addition, in Fig. 2, with a batch gas flushing pouch, the height that can meet or exceed certain X value of no gas leakage；Conversely, If any the packaging bag of gas leakage, the height of the X value is not achieved；So the B point height in detection Fig. 2, so that it may learn tested Gas flushing pouch whether there is leakage problem.

The height (or claiming the height lifted) rotated by detection rotation frame 13, so that it may learn whether packaging bag leaks Gas；The point specifically detected can be very much, the B point being not necessarily limited in Fig. 1 and Fig. 2, and the methods detected are also very much.

In the present invention, rotation push frame 13 can be designed to many patterns, and above situation is only one of those Situation.

7th point.

Drive roll and passive roller are also referred to as driving wheel and follower.

8th point.

Pushing motor 7 can be connected by push transmission parts 8 and the transmission of drive roll 9, and driving drive roll 9 rotates； Drive roll 9 drives push belt 12, passive roller 10 and transition roller 11 to rotate together again.

Manufacture and design it is contemplated that in clamping gas flushing pouch up and down, it is therefore desirable to which accomplish: push belt 12 above is under The conveyer belt 2 in face keeps identical movement velocity.

9th point.

In lifting device, rotating forward active screw rod 4A can be such that lifting nut part 6A rises；Rotate backward active silk Bar 4A can be such that lifting nut part 6A declines.

When rotating active screw rod 4A, by synchronous belt component, rotate passive screw rod 4B also together.Active screw rod 4A is just To rotating, passive screw rod 4B being driven also to rotate forward, increase together two lifting nut part 6A and lifting shaft 5；Conversely, actively Screw rod 4A is rotated backward, passive screw rod 4B is driven also to rotate backward, and declines two lifting nut part 6A and lifting shaft 5 together.

Since lifting shaft 5 can rise or drop, so rotation pushing equipment can also rise or drop, to adjust height, fit Answer the gas flushing pouch of different-thickness size.

10th point.

The case where rotating pushing equipment and lifting device, may refer to Fig. 3, Fig. 4 and Fig. 5 and is understood.Fig. 3 is to turn The sectional perspective schematic diagram of dynamic pushing equipment；Fig. 4 is that lifting device has been made to omit, simplify the stereoscopic schematic diagram of processing；Fig. 5 is figure The stereoscopic schematic diagram that 3 rotation pushing equipment and the lifting device of Fig. 4 fit together.

Fig. 4 is that lifting device has been made to omit, simplify the stereoscopic schematic diagram of processing；Fig. 5 is the rotation pushing equipment and figure of Fig. 3 The stereoscopic schematic diagram that 4 lifting device fits together；Figure 17 is the invention system schematic diagram in embodiment one；Figure 18 is Figure 17 Top view；Figure 19 is the left view of Figure 17.

When using present system, if the model specification of tested packaging bag 50 changes, especially packaging bag 50 Thickness varied widely, need to rotate the progress such as pushing equipment increasing or decreasing by a relatively large margin；In order to meet this The requirement of class situation of change, the present invention in be provided with lifting device, carry out relevant introduction below.

Increase or reduce lifting shaft 5, so that it may increase or reduce rotation pushing equipment.

In the case where system stalls and power-off, handwheel 16 is rotated, active screw rod 4A is rotated simultaneously, in synchronous belt Under the action of component, passive screw rod 4B is also rotated simultaneously.

Screw rod rotation, the lifting nut part 6A positioned at silk rod body are forced to make the lifting moving of sliding property.Due to lifting The inner wall of case 15 is in rectangle, the identical simultaneously dimensional fits of the rectangular profile of inner wall rectangle and lifting nut part 6A, so lifting spiral shell Parent part 6A itself can not make opposite rotation with elevator chamber 15, and lifting nut part 6A can only carry out opposite liter in elevator chamber 15 Drop movement.

Two lifting nut part 6A, which are synchronized, rise mobile or decline movement, in this way, carrying out lifting shaft 5 also Rise mobile or decline movement, and be lifting shaft 5 both ends it is synchronous simultaneously move, thus reach desired functional purpose, i.e., Increase or reduce rotation pushing equipment.

Lifting shaft 5 rises or falls, and exactly rotates rising or falling for pushing equipment, now carries out correlation circumstance explanation: First, lifting shaft 5 is coaxial with transition roller 11, and body portion is through within transition roller 11, rotates and connects with transition roller 11 It connects；Second, the both ends of transition roller 11 are rotatablely connected with rotation push frame 13 respectively.

It finally to be said, when the height of lifting shaft 5 is adjusted in place, i.e. the height of rotation pushing equipment, which adjusts, to be completed When, should also retaining mechanism be used to lock the height and position of lifting shaft 5., first is that preventing screw rod from voluntarily slowly walking about, make height Degree position changes, second is that considering from safety in production angle, to prevent contingency.The main points of locking are: allowing screw rod It is not able to rotate, for this purpose, there are two types of the technical methods that can be taken.First method is arranged between screw rod and elevator chamber 15 Anchor ear component, unclamping anchor ear can be with rotary screw rod, the height to adjust lifting shaft 5；Anchor ear is tightened, screw rod can be made to fix, It can not be rotated further by, to lock the height and position of lifting shaft 5.Second method is that spiral shell is arranged between screw rod and elevator chamber 15 Latch, unclamping bolt can be with rotary screw rod, the height to adjust lifting shaft 5；Bolt is tightened, screw rod can be made to fix, nothing Method is rotated further by, to lock the height and position of lifting shaft 5.

In general, that locking is active screw rod 4A；But it is also possible if locking passive screw rod 4B.

Embodiment three

A certain invention system is also provided with operating display in automation control circuit, has setting height in display screen Column and current detection height column；Also, the packaging bag data detected are saved, and can be taken out point Analysis.It, can artificial setup parameter in height column；In current detection height column, it is shown that the packaging finally detected Bag data.The a certain invention system has been carried out preliminary debugging, and whole system can tentatively be run.

When fine debugging, a certain number of packaging bags are used, wherein there is gastight packaging bag, have also there is gas leakage Packaging bag, carry out test repeatedly.3 test result of height detecting device shows: all gastight packaging bags, height value All greater than 33 millimeters；The packaging bag of all gas leakage, height value is all less than 27 millimeters.In gastight packaging bag, again It takes out one of packaging bag to test repeatedly, test result is the gastight packaging bag, the maximum height detected Value is 34.1 millimeters, and minimum height values are 33.9 millimeters, should statistics indicate that, system or more stable, reliable.

Then, for operator in the height column of display screen, the data of setting are 33 millimeters；Then, the invention system Make packaging bag gas leakage detection on assembly line, effect is fine.Detecting and being divided to through the invention system returns two classes (gas leakage class and not leak Gas class) packaging bag, then through manually being verified one by one, whole is accurate.

It is for further analysis again below in the case of above.

1. the height detecting device 3 of invention system is not the measuring equipment of a standard, the height dimension number that it is obtained According to, if meeting the accuracy in meterological meaning is not emphasis；Emphasis is system and its height detecting device 3 to the same packet Pack is tested repeatedly, data whether high superposed, if data high superposed, in total data, maximum value and most Error very little between small value, then illustrate system and height detecting device is stable and reliable.

2. invention system and height detecting device, their task is that gas leakage packaging bag and gastight packaging bag are known It does not come；Only under the premise of meeting this requirement, set height is just significant in display screen；In other words, in system essence When fine tuning tries, the height set in display screen can be and constantly grope to try, until finally determining setting data can Two classes (gas leakage class and air tight class) packaging bag to be set out like clockwork.

3. the height lifted is rotated by detection rotation push frame 13, to learn thickness of the packaging bag in compression Degree, finally know packaging bag whether gas leakage, such method is the leak detection method of preferential recommendation of the present invention；But this hair Bright there are also multiple other methods, such as the height lifted by detecting passive roller 10, also it can be seen that packaging bag is in compression feelings Depth information under condition, finally it will also be appreciated that packaging bag whether gas leakage；Such detection rotation (or say and lift) is drawn The method for sending out height change, shall fall within the protection scope of the present invention, and be covered by the present invention.

4. detection rotation push frame 13 rotates the height of (lifting), there are many methods；With regard to its sensor or probe For, there are electromagnetic type, eddy current type, condenser type, inductance type, Hall-type, etc..

Technical solution: the system includes Guo Dian testing agency 53；The Guo Dian testing agency 53 is arranged in quilt The position that packaging bag 50 is advanced is surveyed, is electrically connected with automation control circuit；The position of the traveling refer to packaging bag 50 by The position oppressed to push belt 12.

The present embodiment will be illustrated and explain to above-mentioned technical proposal.

Figure 20 is the schematic diagram of 53 facilities of Guo Dian testing agency；In the upper right quarter of Figure 20, downward unidirectional big arrow generation The pressure that table applies rotation frame 13 by press mechanism；The middle and lower part position of Figure 20 is there are two unidirectional small arrow, above small Arrow represents the direction of motion of push belt 12, below small arrow represent the direction of motion of conveying device conveyer belt 2；Label 53 it is small Circle represents Guo Dian testing agency, perhaps represents the sensor in Guo Dian testing agency or represents and passes in Guo Dian testing agency The probe of sensor.

Since packaging bag 50 is clamped jointly by conveyer belt 2 and push belt 12, rotation push frame 13 is with 5 axle center of lifting shaft Line (while being also 11 axial line of transition roller) is that the center of circle rotates counterclockwise, and works as packaging bag 50 and be detached from push belt 12 to the right When, rotation push frame 13 rotates clockwise.Therefore, rotation push frame 13 is being swung always, and the moment is engraved in hair at that time Raw change in location, will appear as from the available continuous data group of height detecting device 3 if the top of data is connected The shape of curve, then, how really unique fixed number according to?

The measure of invention is: when the position where the tested arrival of packaging bag 50 small circle, Guo Dian testing agency 53 is detected Automation control circuit is reported after learning immediately, when automation control circuit was point at the time of reaching small circle with packaging bag 50 It carves, and assert the data that height detecting device 3 obtains at the moment for unique data.When automation control circuit is using intelligence Component, for example be easily to accomplish this point using CPU.

It is now illustrated below for two examples.

First example.When the detection of Guo Dian testing agency 53 learns that packaging bag 50 reaches small circle, automation control is given immediately Circuit processed sends out a pulse signal.Before not receiving pulse signal, although height detecting device 3 is constantly to automation control electricity Elevation information is reported on road, but automation control circuit is ignored；Only when receiving pulse signal, automation control circuit Just receive a present level information report, packaging bag tested for one this be unique elevation information

Second example.Height detecting device 3 constantly reports elevation information, automation control to automation control circuit Circuit is saved elevation information and temporal information together.The detection of Guo Dian testing agency 53 learns that packaging bag 50 reaches small circle When, a pulse signal is sent out to automation control circuit.Automation control circuit is found and pulse signal in the information of preservation Time corresponding elevation information, and with the elevation information for unique valid data.

Is how Guo Dian testing agency 53, which is detected, learnt that packaging bag 50 reaches small circle? there are many its scheme, now with Photoelectric Detection For principle, it is illustrated.

In the two sides of small circle, infrared light-emitting diode is arranged in side, and infrared receiving diode is arranged in the other side.Do not having In the case that packaging bag 50 is blocked, the infrared light that infrared light-emitting diode issues is received by infrared receiving diode.Once packet Pack 50 reaches at small circle, and since light is blocked, infrared receiving diode can not receive infrared light, Guo Dian testing agency 53 It is just reported to automation control circuit, that is, issues a pulse signal.
