Description

Empty mold box detection device of ZB45 packaging machine

Technical Field

The utility model relates to an empty mold box detection device of a ZB45 packaging machine.

Background

In the production process of small cigarette cases of ZB45 small case packing machine in cigarette factory, cigarettes enter packing mould boxes through a cigarette dropping device and then are packed in mould boxes, and the packed mould boxes are conveyed to the next procedure by a conveying belt. In the conveying process, the quality of cigarettes in the mold box needs to be monitored, if the quality does not meet the technological standard, the cigarettes are removed through a subsequent removing station, and the subsequent feeding equipment stops supplying the packaging materials of the mold box. And then, detecting an empty mold box, wherein an optical fiber sensor is mainly used for detecting whether cigarettes which do not meet the process standard in the mold box are removed.

The tobacco powder in the cigarette can cover the optical fiber sensor during production, and the adjustment of the detection sensitivity of the optical fiber sensor is influenced. When the sensitivity of the optical fiber sensor is adjusted to be too low, the problem that cigarettes in the mold box cannot be detected can occur, the mold box with qualified cigarettes is mistaken as an empty mold box by the machine, the supply of aluminum foil paper, inner frame paper, trademark paper and the like which are originally used for packaging the mold box is stopped, the cigarettes which are not packaged are not rejected, the machine is still operated at a high speed, the cigarettes are scattered and arranged on the mold box, and the cigarettes still remain until 6 rounds, so that the equipment safety and the cigarette packet quality are seriously affected. When the sensitivity of the optical fiber sensor is adjusted to be too high, false detection can also occur, so that the machine mistakenly considers that cigarettes exist in the empty mold box, namely the cigarettes which are mistakenly considered not to meet the process standard are not removed, the machine sends out wrong fault prompt, and the vehicle stops.

SUMMERY OF THE UTILITY MODEL

The empty mold box detection device for the ZB45 packaging machine can accurately detect whether a cigarette exists in the mold box, replaces the original optical fiber sensor with the plurality of capacitive proximity switches, ensures the detection accuracy of the empty mold box, avoids A-grade quality accidents caused by that unpacked 'bare cigarettes' are thrown out in a later process and fall into qualified cigarette packets due to the false detection of the optical fiber sensor, and plays a certain role in protecting equipment.

According to an aspect of the embodiment of the utility model, the detection device is arranged on a mould box conveying line and comprises an OR gate circuit and at least two capacitive proximity switches, wherein the at least two capacitive proximity switches face the conveying line to detect cigarettes in a mould box of the ZB45 packaging machine, the output ends of the at least two capacitive proximity switches are connected to the input end of the OR gate circuit, and the output end of the OR gate circuit is connected to a detection signal port of the ZB45 packaging machine electric cabinet empty mould box.

In some examples, the signal output by the output end of the or gate circuit passes through the photoelectric isolator and is input to the empty box detection signal port of the electrical cabinet of the ZB45 packaging machine.

Detailed Description

Fig. 1 shows a schematic view of the empty magazine detector of the ZB45 packaging machine on the magazine conveyor belt 7. Referring to fig. 1, the utility model adopts a plurality of capacitive proximity switches 5 to detect whether cigarettes in a mold box 3 which do not meet the process standard are rejected, the capacitive proximity switches 5 are arranged on a bracket 6, and an induction end faces a mold box conveying belt 7. The present application employs two or more numbers of capacitive proximity switches 5. As shown in fig. 2 and 3, the bracket 6 has a first mounting hole 6-1 and a second mounting hole 6-2 at both ends thereof. One end of the bracket 6 is fixed on the packaging machine through fasteners such as a screw 4 on the first mounting hole 6-1, and the other end is positioned above the die box conveying belt 7. The capacitance type proximity switch 5 is installed in the second installation hole 6-2, the second installation hole 6-2 is a waist groove, and the position of the capacitance type proximity switch 5 is convenient to adjust. The capacitive proximity switch 1 arranged on the bracket 6 faces the conveyer belt 3, and can detect whether cigarettes exist in the mold box 1 on the conveyer belt 3.

The two ends of the power supply of the capacitance type proximity switch 5 are respectively connected with the positive pole and 0V of the power supply. As shown in FIG. 4, the output ends of a plurality of capacitive proximity switches 5 are connected with the input end of an OR gate circuit, and the output end of the OR gate circuit is connected with a ZB45 packaging machine electric cabinet empty mold box detection signal port, so that the original function is ensured. In addition, the output end signal of the OR gate circuit can be input to a detection signal port of an empty mold box of the electrical cabinet of the ZB45 packaging machine after passing through the photoelectric isolator, so that the anti-interference capability is enhanced.

The optical fiber sensor judges the existence of the cigarette in the mold box through the reflected light signal of the end face of the cigarette filter. When infrared light emitted by the optical fiber sensor irradiates micro gaps among cigarettes, reflected light signals cannot be received, and the fact that no cigarette exists in the mold box is judged, and the condition of false detection occurs. The capacitive proximity switch 5 senses the surface, and the capacitive proximity switch 5 is not influenced by a tiny gap between cigarettes, so that the condition of false detection cannot occur.

In the production process of the ZB45 packaging machine, when multiple packs of cigarettes are continuously removed, due to the fact that designed defects cannot avoid the condition of missed removal, unqualified missed cigarettes are paid out at the X position (2Y611), namely, an empty mould box detection position 1 shown in the figure 1, at the moment, the empty mould box detection device is in action, any one of a plurality of capacitive proximity switches 5 has high-level output and is input to the input end (an empty mould box detection signal port) of the ZB45 packaging machine N12 board through an OR gate circuit, the PLC controller of the packaging machine executes the original empty mould box detection function, the machine stops, the 'removed cigarette failure' is displayed, and the cigarettes are removed at a cigarette removal position 2(Z station). If one or more of the capacitive proximity switches are subjected to false detection, the output is at least one high level and at least one low level, the detection signal is processed by an OR gate circuit, the output is still high level, the corresponding packaging material cannot be stopped, cigarettes cannot be thrown out in the subsequent process, and the problem of cigarette throwing caused by stopping supplying the packaging material when the original equipment only uses one group of optical fiber sensors for false detection is solved.

If the missing removal condition does not exist, namely the unqualified cigarettes are removed when being conveyed to the empty mould box detection position 1, no cigarettes exist in the cigarette mould box, the detection output of the capacitive proximity switch 5 is low level, and the equipment operates normally.
