In order to make those skilled in the art better understand the technical features of the present creation, the present creation will be further described in detail below in conjunction with the drawings and embodiments.

Please refer to FIG. 1 and FIG. 2 , the present invention provides a system 1 for detecting missing printing and making up printing, which is installed on the packaging device machine 10 , and the packaging device machine 10 is sequentially provided with a first packaging film conveying unit 20 , The second packaging film conveying unit 40 and the third packaging film conveying unit 30 are used to convey the packaging film body 2. The packaging film body 2 may include a plurality of packaging units, and each packaging unit can package the corresponding product after being processed by the packaging device. .

Based on the above, the system 1 for detecting and replenishing printing of the present invention includes a marking sensor 11 , a marking device 12 , an indexing sensor 13 and a controller 14 . The marking sensor 11 is disposed on the packaging device machine 10 corresponding to the third packaging film conveying unit 30 , and the marking sensor 11 senses the marking points of each packaging unit of the packaging film body 2 passing through the third packaging film conveying unit 30 to generate A marker sensing signal is generated. This does not limit the position of the marking point on the packaging unit, nor does it limit whether there are other marking points on the packaging unit. Preferably, the marking point can be located in the front section of the packaging unit, so that the packaging unit can pass the marking sense at the beginning. In the early stage of the sensor 11, the marked point can be sensed by the marking sensor 11. It is found that the reaction time of the subsequent reprinting can be prolonged, but the above is only an example, not a limitation.

The marking device 12 is disposed on the packaging device machine 10 corresponding to the second packaging film conveying unit 40 , and is electrically connected to the marking sensor 11 to receive the marking sensing signal and print each packaging unit accordingly. Wherein, the content printed on the packaging unit is not limited here, and may preferably be the date of manufacture or the expiration date, but the above is only an example, not a limitation.

The indexing sensor 13 is disposed on the packaging device machine table 10 corresponding to the first packaging film conveying unit 20 , and continuously senses the rotation of the first packaging film conveying unit 20 to generate an indexing signal.

The controller 14 is disposed on the packaging device machine 10, and is electrically connected to the marking sensor 11, the marking device 12 and the indexing sensor 13. The controller 14 receives and accumulates the indexing signals to generate accumulated degrees, and continues In the state of receiving the indexing signal, as the first packaging film conveying unit 20 continues to rotate, the accumulated degree will also increase accordingly. When the controller 14 receives the mark sensing signal, if the accumulated degree is below the threshold degree, it will The accumulated degree is reset to zero and the next accumulated degree is re-accumulated. If the controller 14 has not received the mark sensing signal when the accumulated degree exceeds the threshold degree, the controller 14 will generate a control signal and transmit it to the marking device 12 for correcting. Packaging unit for printing.

For example, the distance between the marking points on each packaging unit should be equidistant, and the distance between the marking points on each packaging unit is also equal to the length of one packaging unit. The signal is accumulated to 50, that is, the accumulated degree is 50. At this time, the controller 14 can set 50 as the threshold degree. Under normal circumstances, the marking sensor 11 senses the marking point of the current packaging unit and generates the marking sensing signal. , the accumulative degree of the controller 14 will be reset to zero and re-accumulated, so when the accumulated degree of the next time is accumulated to 50, the marking sensor 11 should sense the marking point on the next packaging unit. Mark sensor 11 does not sense If the marking point is marked, the marking sensing signal cannot be generated, and the marking device 12 cannot print according to the marking sensing signal, that is, a situation of missing printing occurs; The controller 14 does not receive the mark sensing signal when the threshold degree exceeds 50, so it determines that the marking device 12 has missed printing, and immediately generates a control signal and transmits it to the marking device 12, so that the marking device 12 can make up It is understood that the position of the supplementary printing on the packaging unit will be located after the original position to be printed, but should not exceed the end of the packaging unit.

As can be seen from the above example, since the threshold degree is set based on the spacing between the marking points of each packaging unit, the threshold degree can also be said to correspond to the length of the packaging unit.

Further, the controller 14 can set a locking degree, the locking degree is less than the threshold degree, for example, the threshold degree is 50, and the locking degree is 45; when the accumulated degree exceeds the locking degree, the controller 14 enters the locked state to continuously monitor the accumulated degree. Whether the mark sensing signal is received before the degree exceeds the threshold degree, if so, the lock state is released, the accumulated degree is reset to zero, and the next accumulated degree is re-accumulated. In this way, the controller 14 can more accurately determine whether a missing print occurs in a fixed interval, and can also avoid misjudgment and accumulation of subsequent image indexing signals caused by receiving the mark sensing signal before the index is locked.

Referring to FIG. 3 , in more detail, the first packaging film conveying unit 20 may be provided with an indexing plate 130 coaxially, the indexing plate 130 will rotate synchronously with the first packaging film conveying unit 20 , and the indexing plate 130 has scales to For the indexing sensor 13 to sense, the indexing sensor 13 can sense the indexing plate 130 to generate an indexing signal.

In another embodiment, the controller 14 can set a preset time, such as one minute, within the preset time, when the control signal is generated more than the preset number of times, the controller 14 can generate the warning signal; or continuously generate When the number of control signals is greater than a preset number, the controller 14 A warning signal can also be generated; through this, the relevant staff is notified to go to solve the problem, or the operation of the packaging device is stopped first according to the warning signal, waiting for the staff to check.

Continuing from the above, a system 1 for missing print detection and reprinting provided by this creation can judge whether there is a missing print situation according to the accumulated number of degrees and whether the mark sensing signal is received. If the accumulated number of degrees exceeds the threshold degree, The controller 14 then transmits the control signal to the marking device 12 for real-time reprinting of the package.

The above are only the preferred embodiments of the present creation. It should be pointed out that for those skilled in the art, some improvements and modifications can be made without departing from the principles of the present creation. These improvements and modifications should also be It is regarded as the scope of protection of this creation.
