Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to an automatic testing device for assisting small box appearance inspection of a packaging machine. Background Art

[0002] In order to ensure the product quality of the packaging machine (such as the ZB416 model), maintenance workers need to conduct a spot smoke test on the small box appearance inspection mechanism when debugging the equipment.

[0003] However, because the small-box appearance inspection image acquisition box is located above the high cigarette runway, maintenance workers need to climb a ladder to the runway and pass the inspection cigarettes one by one through the appearance inspection image acquisition box to capture appearance images and perform relevant tests. This process requires high-altitude work and is quite dangerous. If the operation is not carried out properly during the high-altitude work, accidents are likely to occur, posing a significant safety hazard and making it difficult to meet production requirements. Utility Model Content

[0004] In view of the above, the present invention aims to provide an automatic testing device for assisting packaging machines in inspecting the appearance of small boxes, so as to solve the above-mentioned technical problems.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] The utility model provides an automatic testing device for assisting packaging machines in appearance spot inspection of small boxes, which comprises: a PLC, a box cigarette runway, a front smoke blocking cylinder, a rear smoke blocking cylinder, a fixing frame, a cigarette taking cylinder, an upper limit magnetic switch, a lower limit magnetic switch, a rotating cylinder, a suction cup, a spot inspection cigarette placement box, an appearance inspection image acquisition box, a photoelectric switch, a rejection mechanism, and a cigarette receiving box;

[0008] The fixing bracket is installed on the cigarette runway, and the front smoke cylinder is installed on the cigarette runway in front of the fixing bracket; the appearance detection image acquisition box is installed on the cigarette runway behind the fixing bracket, and the appearance detection image acquisition box is used to capture the appearance image of the cigarettes passing through the inspection; the rear smoke cylinder is installed on the cigarette runway behind the appearance detection image acquisition box;

[0009] The cigarette removal cylinder and the inspection cigarette placement box are mounted on the fixing frame, and the inspection cigarette placement box is located below the cigarette removal cylinder. The inspection cigarette placement box is used to place inspection cigarettes. The range of the cigarette removal cylinder's up and down movement is defined by the upper limit magnetic switch and the lower limit magnetic switch. The rotating cylinder is connected to the bottom of the cigarette removal cylinder, and the suction cup is connected to the rotating cylinder. The suction cup is used to suck the inspection cigarettes from the inspection cigarette placement box.

[0010] The photoelectric switch and the rejection mechanism are both installed behind the appearance inspection image acquisition box. The photoelectric switch is used to detect the position of the inspected cigarettes, and the rejection mechanism is used to reject the inspected cigarettes after image acquisition from the box cigarette runway and drop them into the cigarette receiving box located below.

[0011] In at least one possible implementation, the structure of the inspection cigarette placement box can be used to place multiple packs of inspection cigarettes stacked horizontally.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0019] Figure 1 This is a schematic diagram of an automatic testing device for assisting packaging machine small box appearance inspection provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0020] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] The utility model proposes an embodiment of an automatic testing device for assisting packaging machine in inspecting the appearance of small boxes. Specifically, Figure 1 As shown, it includes: a PLC (not shown in the figure), a cigarette runway 100, a front smoke cylinder 2, a rear smoke cylinder 3, a fixing frame 4, a cigarette removal cylinder 5, an upper limit magnetic switch 6, a lower limit magnetic switch 7, a rotating cylinder 8, a suction cup 9, a cigarette inspection placement box 11, an appearance inspection image acquisition box 12, a photoelectric switch 13, a rejection mechanism and a cigarette receiving box 15.

[0022] The input end of the PLC is connected to the upper limit magnetic switch 6, the lower limit magnetic switch 7, the proximity switch 10, and the photoelectric switch 13 signals, and the output end of the PLC is connected to the front smoke cylinder 2, the rear smoke cylinder 3, the smoke taking cylinder 5, the rotating cylinder 8, and the rejection mechanism signals.

[0023] Preferably, a belt motor 1 installed above the cigarette box runway 100 can drive the cigarette box runway 100 to operate in a predetermined running direction; the fixed frame 4 is installed at the cigarette box runway 100 (can be one side), and the front smoke blocking cylinder 2 is installed in front of the fixed frame 4 (as shown in the figure, relative to the running direction of the runway) at the cigarette box runway 100 (can be one side). When testing the inspection cigarette packs, the action of the front smoke blocking cylinder 2 can temporarily block the normal small boxes of cigarettes conveyed by the packaging machine.

[0024] The appearance inspection image acquisition box 12 is installed at the cigarette runway 100 (which can be one side) behind the fixed frame 4 (as shown in the figure, relative to the running direction of the runway). The appearance inspection image acquisition box 12 is used to collect appearance images of the cigarettes passing through for inspection. Therefore, it can be understood that an image collector, such as an industrial camera, is provided therein.

[0025] The rear smoke blocking cylinder 3 is installed at the cigarette runway 100 (which can be one side) behind the appearance inspection image acquisition box 12 (as shown in the figure, relative to the running direction of the runway). Similarly, when the inspection cigarette packs are tested, the action of the rear smoke blocking cylinder 3 can temporarily block the inspection cigarettes from flowing into the subsequent processing steps.

[0026] The cigarette taking cylinder 5 and the inspection cigarette placement box 11 are installed on the fixed frame 4, and the inspection cigarette placement box 11 is located below the cigarette taking cylinder. The inspection cigarette placement box 11 is used to place the cigarette packs to be inspected (preferably in a flat position so that they can be reliably adsorbed by the suction cup mentioned below). The cigarette taking cylinder 5 can perform up and down movements, and the upper and lower limit ranges of the movement of the cigarette taking cylinder 5 are detected by the upper limit magnetic switch 6 and the lower limit magnetic switch 7. It can be understood that the upper limit magnetic switch 6 and the lower limit magnetic switch 7 can both be located on the cylinder body of the cigarette taking cylinder 5. When the cigarette pack is lifted by the cigarette taking cylinder 5 to the vicinity of the cigarette runway 100, the upper limit magnetic switch 6 is triggered. When the cigarette packs in the inspection cigarette placement box 11 are taken out, the cigarette taking cylinder 5 moves downward to the predetermined lower limit position in the inspection cigarette placement box 11, which triggers the lower limit magnetic switch 7, so that the cigarette taking cylinder 5 no longer takes cigarettes back and forth.

[0027] The bottom of the cigarette taking cylinder 5 is connected to the rotating cylinder 8, and the suction cup 9 is connected to the rotating cylinder 8. The suction cup 9 is used to suck the inspection cigarettes in the inspection cigarette placement box 11; it can be further pointed out here that the rotating cylinder 8 can be flipped at least 90 degrees. For example, after the rotating cylinder flips 90 degrees, the cigarette pack adsorbed on the suction cup can be transformed from a flat posture to an upright posture, and can then be safely placed on the cigarette box runway 100.

[0028] Regarding the adsorption and release actions of the suction cup 9, a specific explanation can be given here as follows: a proximity switch 10 can be installed on the suction cup 9 to detect whether the suction cup 9 is in contact with the cigarette pack (i.e., inspection cigarettes) in the inspection cigarette placement box 11. For example, if the suction cup 9 is in contact with the inspection cigarette pack, the proximity switch 10 will feedback a signal to activate the conventional negative pressure mechanism, so that the suction cup 9 generates negative pressure and sucks up the cigarette pack; and for releasing the cigarette pack, the trigger signal of the upper limit magnetic switch 6 can be used to cut off the negative pressure air path to allow the cigarette pack to detach from the suction cup 9.

[0029] Continuing from the previous description, the photoelectric switch 13 is mounted behind the appearance inspection image acquisition box 12 and is used to detect the arrival of inspection cigarettes, thereby triggering the rejection mechanism to cause the inspection cigarettes, after image capture, to fall from the cigarette runway 100 into the cigarette receiving box 15 below. The rejection mechanism may include an air blow valve 14 mounted behind the appearance inspection image acquisition box 12. Once the photoelectric switch 13 detects inspection cigarettes, it triggers the air blow valve 14 with an electrical signal, blowing the inspection cigarettes into the cigarette receiving box 15.

[0030] Finally, it can be added that the testing device includes a touch screen connected to the PLC signal. The touch screen is installed near the packaging machine to facilitate maintenance workers to operate it through the touch screen. The signal transmission process can be referred to as follows. The touch screen communicates with the PLC through the field bus, and can send touch signals to the PLC, and the PLC sends command signals to the actuator.

[0031] In summary, the main design concept of the present invention is that it consists of a PLC, a cigarette runway, a front smoke blocking cylinder, a rear smoke blocking cylinder, a fixed frame, a cigarette removal cylinder, an upper limit magnetic switch, a lower limit magnetic switch, a rotating cylinder, a suction cup, a spot inspection cigarette placement box, an appearance inspection image acquisition box, a photoelectric switch, a rejection mechanism, and a cigarette receiving box. The front and rear double cylinders perform the smoke blocking function, and the cigarette removal cylinder, the rotating cylinder, and the suction cup cooperate to remove cigarette packs from the spot inspection cigarette placement box and place them on the runway. After the cigarette packs are transported to the appearance inspection image acquisition box for image pickup, the photoelectric switch and the rejection mechanism cooperate to remove them from the runway and place them in the cigarette receiving box, completing a round of automatic cigarette removal and photography. This process is then repeated until the spot inspection cigarette placement box is completely removed. The present invention greatly facilitates maintenance workers in quickly completing the automatic testing process of small box appearance inspection spot inspection cigarettes when debugging the packaging machine. There is no need to rely on climbing a ladder to perform spot inspection cigarette testing operations, eliminating safety risks, improving the efficiency of equipment debugging, and reducing the labor intensity of maintenance workers.
