[0002] In the production process of cigarette products, the appearance quality of the finished cigarette cartons is crucial. Consumers' quality perception of a product first comes from its appearance, and neatly folded cellophane can enhance consumers' recognition of the product and the brand.

[0003] In the related art, in order to detect cellophane, carton packaging machines of models such as FOCKE408 usually adopt an optoelectronic detection method to detect whether the cellophane is offset during transportation, and accordingly determine whether the cellophane wrapped around the carton is neatly folded. However, the optoelectronic detection method has the following disadvantages: the sensitivity of the optoelectronic sensor is not high, and it is easily interfered in a dusty environment, resulting in misjudgment, poor detection effect, causing the machine to stop due to false alarm, or producing cartons with unqualified cellophane folding; the optoelectronic sensor requires a fixed installation position, and the space available for installing the optoelectronic sensor on the FOCKE408 carton packaging machine is relatively narrow, resulting in inconvenient installation and occupying the space required for repairing the packaging machine, leading to inconvenient maintenance.

[0035] refer toFigures 1 to 5 , some embodiments of the present disclosure provide a cellophane detection system for a strip carton packaging machine, including a cellophane conveying device 1, a packaging turret 2, a negative pressure detection channel, and a negative pressure detection head 3.

[0036] The cellophane conveying device 1 is configured to convey the cellophane 6 required for packaging strip cartons. The packaging turret 2 has a first receiving groove 21 and a receiving surface 22 correspondingly arranged on the side of the first receiving groove 21 along the circumferential direction of the packaging turret 2. The first receiving groove 21 has a preset rotation position and is configured to receive strip cartons at the preset rotation position. The receiving surface 22 is configured to receive the cellophane 6 conveyed by the cellophane conveying device 1 and convey the cellophane 6 as the packaging turret 2 rotates, so that in a state where the first receiving groove 21 rotates to the preset rotation position, the cellophane 6 can be wrapped around the outside of the strip carton received in the first receiving groove 21. The negative pressure detection channel is configured to be connected to a negative pressure air source, and the openings of the two negative pressure detection channels are respectively opened at the edges on both axial sides of the receiving surface 22 along the packaging turret 2. The two negative pressure detection heads 3 are correspondingly arranged in the two negative pressure detection channels. The negative pressure detection head 3 is configured to detect the negative pressure of the negative pressure detection channel where it is located in a state where the first receiving groove 21 rotates to the preset rotation position, so as to obtain the negative pressure detection information on the corresponding receiving surface 22. The negative pressure detection information is used to indicate whether the side edges of the cellophane 6 pass through the opening positions of the two negative pressure detection channels.

[0037] Optionally, referring to Figure 2 , a plurality of first receiving grooves 21 are distributed along the circumferential direction of the packaging turret 2. In a state where each first receiving groove 21 rotates to the preset rotation position, the corresponding two negative pressure detection heads 3 respectively detect the negative pressure of the negative pressure detection channels where they are located, so as to obtain the negative pressure detection information on the corresponding receiving surface 22. The receiving surface 22 can be arranged on the upstream side or the downstream side of the corresponding first receiving groove 21 along the rotation direction of the packaging turret 2.

[0038] Optionally, referring to Figure 3 , the cellophane detection system of the strip carton packaging machine further includes a folding turret 8. The folding turret 8 acts on the packaging turret 2. The folding turret 8 has a second receiving groove 81. The blank of the strip carton conveyed from the upstream process is folded and formed after passing through the folding turret 8, and the rotation movement of the folding turret 8 matches the rotation movement of the packaging turret 2. When a certain first receiving groove 21 on the packaging turret 2 rotates to the preset rotation position, the opening of the first receiving groove 21 and the opening of the second receiving groove 81 face each other, and the folded and formed strip carton can be pushed into the first receiving groove 21 under the action of a pushing mechanism. The cellophane 6 is wrapped around the outside of the strip carton as the strip carton is pushed into the first receiving groove 21. Referring to Figure 4 and Figure 5 , the principle of obtaining the negative pressure detection information on the corresponding receiving surface 22 by the negative pressure detection head 3 in the embodiments of the present disclosure is as follows.

[0039] If the opening position of a negative pressure detection channel is blocked by the cellophane 6, the cellophane 6 will block the airflow through the negative pressure detection channel, and the absolute value of the negative pressure detected by the negative pressure detection head 3 in this negative pressure detection channel will be less than a preset value; if the opening position of this negative pressure detection channel is not blocked by the cellophane, the opening of this negative pressure detection channel will be directly connected to the outside, which does not affect the airflow through the negative pressure detection channel, and the absolute value of the negative pressure detected by the negative pressure detection head 3 in this negative pressure detection channel will be greater than or equal to this preset value.

[0040] Considering that the openings of the two negative pressure detection channels are respectively arranged at the edges of the receiving surface 22 along both axial sides of the packaging turret 2, and the conveying direction of the cellophane 6 is perpendicular to the axis of the packaging turret 2, in the case of normal conveying of the cellophane 6, the positions of the two side edges perpendicular to the conveying direction respectively correspond to the opening positions of the two negative pressure detection channels. When a negative pressure detection head 3 detects that the absolute value of the negative pressure in the negative pressure detection channel where it is located is greater than or equal to this preset value, it indicates that a side edge of the cellophane 6 has passed through the opening position of the corresponding negative pressure detection channel. When a negative pressure detection head 3 detects that the absolute value of the negative pressure in the negative pressure detection channel where it is located is less than this preset value, it indicates that no side edge of the cellophane 6 has passed through the opening position of the corresponding negative pressure detection channel.

[0041] If no side edge of the cellophane 6 has passed through the opening positions of the two negative pressure detection channels, it indicates that the conveying state of the cellophane is normal, and the qualified strip cartons will be conveyed to the next process. If no side edge of the cellophane 6 has passed through the opening position of one of the two negative pressure detection channels while a side edge of the cellophane 6 has passed through the opening position of the other, it indicates that there may be a problem of cellophane position deviation. If no side edge of the cellophane 6 has passed through the opening positions of the two negative pressure detection channels, it indicates that there may be a problem of cellophane missing.

[0042] The cellophane detection system of the strip carton packaging machine provided by the embodiments of the present disclosure uses the negative pressure detection method to detect the conveying state of the cellophane. Compared with the photoelectric detection method, the negative pressure detection method does not need to consider the light transmission performance of the cellophane in environments such as dust, and the detection process is not easily interfered, which can reduce the probability of misjudgment during the detection process and improve the detection accuracy. Therefore, the cellophane detection system of the strip carton packaging machine provided by the embodiments of the present disclosure can improve the detection effect of the conveying state of the cellophane.

[0043] In some embodiments, the receiving surface 22 is provided with a plurality of adsorption ports 23, and a negative pressure pipeline is arranged inside the packaging turret 2. The adsorption ports 23 are configured to be connected to a negative pressure air source through the negative pressure pipeline, so that the receiving surface 22 can adsorb the cellophane 6 conveyed by the cellophane conveying device 1 through the adsorption ports 23. Among them, the negative pressure detection channel is arranged in the negative pressure pipeline, and the opening of the negative pressure detection channel is the adsorption port 23.

[0044] Reference Figure 4 and Figure 5 , negative pressure detection heads 3 are respectively arranged in the negative pressure pipelines corresponding to the two adsorption ports 23 for detecting the conveying state of the cellophane 6, which are represented by solid line contours, and the other adsorption ports 23 are represented by dotted line contours.

[0045] In this embodiment, the negative pressure detection channel utilizes the negative pressure pipeline required for the packaging turret 2 to convey the cellophane itself. The negative pressure detection head 3 is arranged in the negative pressure pipeline. Therefore, compared with the photoelectric detection method, the method of detecting the conveying state of the cellophane by negative pressure does not require additional installation space, and thus will not occupy the space required for maintaining the packaging machine due to the compact structure of the strip carton packaging machine itself, and this detection method will not bring additional energy consumption.

[0046] In some embodiments, reference Figure 6 , the cellophane detection system of the strip carton packaging machine further includes a rejection device 7 and a control device 5. The rejection device 7 is arranged downstream of the packaging turret 2 along the conveying direction of the strip carton, and is configured to reject the strip carton from its conveying path. The control device 5 is signal-connected to the negative pressure detection head 3 and the rejection device 7. The negative pressure detection information includes abnormal detection information indicating that the side of the cellophane 6 does not pass through at least one of the opening positions of the two negative pressure detection channels. The control device 5 is configured to, in the state where the first receiving groove 21 rotates to a preset rotation position, in response to the abnormal detection information, cause the rejection device 7 to reject the corresponding strip carton from its conveying path.

[0047] The rejection device 7 can be a push rod, a lever, etc. or other devices capable of rejecting the strip carton from its conveying path. For example, the rejection device 7 is a push rod whose moving direction is perpendicular to the conveying direction of the strip carton. In this embodiment, through the rejection device 7, the strip cartons packaged when the conveying state of the cellophane is abnormal can be promptly rejected from the conveying path, thereby reducing the risk of unqualified strip cartons flowing into the market.

[0048] In some embodiments, reference Figure 6 , the cellophane detection system of the strip carton packaging machine further includes an alarm device 4 and a control device 5. The alarm device 4 is configured to emit an alarm signal. The control device 5 is signal-connected to the negative pressure detection head 3 and the alarm device 4. The negative pressure detection information includes abnormal detection information indicating that the side of the cellophane 6 does not pass through at least one of the opening positions of the two negative pressure detection channels. The control device 5 is configured to, in response to the negative pressure detection information obtained continuously for a preset number of times being all abnormal detection information, cause the alarm device 4 to emit an alarm signal to prompt that the cellophane 6 is in an abnormal conveying state and / or the strip carton packaging machine needs to stop.

[0049] In this embodiment, the preset number of times can be determined according to the operating parameters of the strip carton packing machine. For example, it can be set to two, three, four, five, etc. When the negative pressure detection information obtained for the consecutive preset number of times is all abnormal detection information, it indicates that the conveying state of the glassine paper has been abnormal for a relatively long time continuously. At this time, the alarm device 4 can timely remind the operator to pay attention to the conveying situation of the glassine paper or directly take measures to stop the machine by sending out corresponding alarm signals, thereby avoiding the generation of more unqualified strip cartons for packaging.

[0050] The alarm signal can be a sound signal and / or a light signal. Optionally, the alarm device 4 is integrated on the human-machine interface. The human-machine interface is configured to display the alarm signal.

[0051] Optionally, in some embodiments, the glassine paper detection system of the strip carton packing machine includes a combination of the rejection device 7, the alarm device 4, and the control device 5 mentioned above.

[0052] Some embodiments of the present disclosure also provide a strip carton packing machine, including the aforementioned glassine paper detection system.

[0053] The strip carton packing machine provided by the embodiments of the present disclosure has the advantages of the aforementioned glassine paper detection system.

[0054] In some embodiments, the control device described above can be implemented as a general-purpose processor, a programmable logic controller (PLC for short), a digital signal processor (DSP for short), an application specific integrated circuit (ASIC for short), a field-programmable gate array (FPGA for short), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any suitable combination thereof for performing the functions described in the present disclosure.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still modifications can be made to the specific implementation manners of the present disclosure or equivalent replacements can be made to some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
