Inspection Machine (Tapping Inspection)
Beverage cans are typically pressurized cans by nitrogen gas filling or carbonation, and vacuum cans that draw a negative pressure when cooled after having been filled at a high temperature. The tapping inspection machine can determine the degree of vacuum by analyzing the sound vibration that occurs from tapping the bottom of the can.
CCD-A2 Case Tapping Inspection Machine
This new model of tapping inspection machine can automatically evaluate the degree of vacuum in packed canned beverages, and detect the level of can expansion, then print out the results. The internal pressure of the can after filling can be evaluated by the resulting sound frequency from tapping the can bottom. An occurrence of internal expansion during the filling process can be detected by an attached displacement sensor to determine the total contour change of the lid surface (on 3 piece cans, the flat lids, and on TULC cans, the bottom), thus maintaining high consistency and quality.
- Shortening the time it takes to change design
- As it is equipped with fully a automatic design changeover capability, pre-registering the can design and changing the packaging configuration can be easily done using a touch panel.
- Simplification of built in operations
- As the attached caster, above a common base, is outfitted with all the equipment, transfer can be done with ease.
There is a cost reduced version, which is the CCD-B, where design change over is partially a manual procedure, depending on the handling.
The equipment layout and appearance is the same as the CCD-A2 case tapping inspection machine.
PED-4 Inline Tapping Inspection Machine
Tapping inspection is conducted inline, within the beverage filling equipment. If the inspection machine creates an emitted sound frequency from the can that is beyond a fixed range limit, the can will be rejected from atop of the line. Furthermore, as each can’s temperature is different, the frequency generated from tapping each can will differ, so the can temperature at the equipment will be measured one by one, and then, depending on the initial temperature, added revisions will be made accordingly to counter unwanted inconsistencies. Additionally, an aggregate summary of these measured results can be printed out.
- Workability improvements
- Because pre registration can be done for each can type’s set value parameters, can type production changeover productivity is improved. Additionally, by adopting a touch panel, operability is also improved.
- Improvement in the displacement measurement function
- By adding an optional sensor, the bottom center depth (BCD) can be measured; the distance to the bottom and the can height is measured and calculated. Compared with using only traditional displacement sensors, an increase in measurement accuracy is realized.
