The discharge turret part 10 is composed of an upper surface 14 and a lower surface 16, and sensors 30 and 40 are mounted on the upper and lower surfaces. The cigarette box is supplied from the turret 12 on the right side of FIG. 1, and the cigarette box is conveyed through the transfer part 18 between the upper surface 14 and the lower surface 16 of the discharge turret part 10. Sensors 30 and 40 detect the upper and lower parts of the cigarette box 60 being transferred. The sensor transmits a signal to the controller 70, and the controller controls the device by calculating the transmitted signal.

The sensing device, ie sensor, used in the present invention is a proximity sensor. A proximity sensor is a sensor that detects an object without contact, which determines if an object is in proximity before contacting another object. Preferably, the present invention utilizes an inductive proximity sensor in this proximity sensor. Inductive proximity sensors are used to detect the surface of metals and use the principle that the magnitude of the oscillation decreases when a metal object is in close proximity.

Preferably, the present invention may use IA12ASN04POM1 (sensing distance of about 3-4 mm) and IA08BSN26POM5 (detection distance of about 2-3 mm), which are proximity switch induction sensors manufactured by CARLO VAVAZZI INDUSTRI. As shown in FIG. 1, these sensors are respectively installed on the upper surface 14 and the lower surface 16 of the discharge turret portion 10 of the cigarette box conveying apparatus. That is, the upper sensor 30 such as IA12ASN04POM1 is installed on the upper surface 14 of the discharge turret part 10, and the lower sensor 40 such as IA08BSN26POM5 is installed on the lower surface 16 of the discharge turret part 10. Can be. The upper sensor 30 detects the cigarette pack of the upper row in the cigarette box, and the lower sensor 40 detects the cigarette pack of the lower row. Preferably, five or more sensors may be installed on the upper and lower surfaces, respectively.

The sensing method using the inductive proximity sensor of the present invention is described in detail below. The sensors 30 and 40 detect the metal foil included in the cigarette pack 50 and transmit a signal to the controller to determine whether there is an abnormality of the cigarette pack.

That is, if the cigarette pack 50 is lacking in the cigarette box 60, at least one or more of the five sensors disposed in each of the upper and lower parts can not detect the metal foil in the cigarette pack, so that the cigarette pack in the cigarette box 60 You will recognize that you are missing.

During manufacture and packaging of the product, the lid of the cigarette pack 50 is incorrectly folded, the outer paper of the cigarette pack 50 is pressed, damaged, adhesive flows out, the cigarette pack 50 and the cigarette The case where the wrapping wrap of the box 60 overlaps occurs. These problems affect the metal foil by pressing or deforming the metal foil. When the metal foil in the cigarette pack is pressed or deformed, it is out of the sensing range of the sensor, so that the sensor does not detect the metal foil or the signal value transmitted to the controller is different from the signal value of the normal product. Therefore, if there is a defect in the product, it can be found through the signal sent to the control unit, the cigarette pack or the cigarette box is defective.

The defects of the cigarette box and the cigarette pack can be seen from the table below. This table contains data on defective products found during one year of installation of the system of the present invention. Accordingly, it should be understood that various problems arising in the manufacture and packaging of tobacco could be solved by the sensing system of the present invention. (Note that the number at the top of the table is indicated by numbering the manufacturing equipment)

On the other hand, it is not preferable that the ten sensors 30, 40 are arranged so as to be located at the center of each pack of five each in the upper and lower parts. For example, if one cigarette pack 50 is removed from the upper and / or lower rows in the cigarette box 60 and only four are arranged, that is, arranged as shown in FIG. This is because there is a possibility of detecting that the cigarette pack 50 is all contained.

To solve this, a preferred arrangement of the sensors 30, 40 is shown in FIG. 2 and 3 are cross-sectional views of the discharge turret portion 10 of FIG. 1 taken along the line II-II. As shown, the sensors other than the sensor 30 in the middle is preferably positioned to slightly deviate from the center of each cigarette pack 50 toward the longitudinal end of the cigarette box. 2, it can be seen that the sensors 30, 40 are slightly outwardly away from the center lines a-a, b-b, c-c and d-d of the pack of cigarettes indicated by dotted lines. That is, it is preferable that the sensor is disposed at a distance slightly longer than the width of the cigarette pack from the centrally located cigarette pack toward the longitudinal end of the cigarette box.

Also, more preferably, the upper sensor 30 is preferably disposed on the lid portion of each cigarette pack. The metal foil may be missing from the cover of the cigarette pack 50, and there is a lot of paper folding process in the cover of the cigarette pack. It is understood that it is desirable to be arranged.

4 shows a configuration diagram in which the present invention operates. As shown, the cigarette box 60 discharged from the turret 12 is passed along the transfer path in the direction of the left arrow through the discharge turret portion. Sensors 30 and 40 mounted on the upper and lower parts are connected to the controller 70 and transmit a signal. The controller 70 receives a signal transmitted from the sensors 30 and 40 and controls the cigarette manufacturing apparatus by a program of the controller.

Preferably, when the cigarette box 60 lacking the cigarette pack 50 or the cigarette box 60 including the defective cigarette pack 50 passes through the sensor, the signal value transmitted to the controller 70 is a normal product. It will be different from the signal value when it passes. Therefore, if the control unit does not have a signal for detecting the metal foil or the value of the detected signal is different from the normal signal value, the control unit processes the signal by the program in the control unit, the signal to stop the operation of the cigarette box 60 transfer device Can be generated. When the device is stopped by the control unit, the operator of the factory can prevent the defective product from being produced by operating the device again after removing the defective cigarette box 60.

Alternatively, it will be appreciated that if there is an error in the signal detected from the sensor, the controller may connect a device (indicated by the dotted line in FIG. 4) to automatically discharge the cigarette box. The control unit and the discharging device may be any device as long as it is a general system used in the device for transferring a product.

Thus, by the system of the present invention, when the cigarette box 60 is discharged from the turret 12 and passes through the conveying portion 18 of the discharge turret portion 10, the upper surface 14 of the discharge turret portion 10 and Sensors 30 and 40 mounted on the lower surface 16 detect the metal foil contained in the cigarette pack 50 in the cigarette box, and transmit a signal to the controller 70, and the controller transmits a signal value to a normal product. If the signal value is different from the control to stop or discharge the device. This principle makes it possible to prevent the above mentioned defective products from entering the market.

According to the present invention, the cigarette pack is missing from the cigarette box, or the damage of each cigarette pack and the cigarette box in the cigarette box can be detected, thereby removing the defective products. Therefore, it is possible to obtain the effect of increasing the reliability of the product by removing the defective product.
