At this time, as shown in part B shown in Figure 6, it is preferable that a specific part (reference part) of the composite cigarette filter is cut.

If part A or C is cut instead of the standard part, the defective part is generated continuously.

The sensor 700 according to the present invention detects the displacement of the composite cigarette filter and transmits the detected result to the controller 800.

Sensor 700 detects the color and the number of times the color of the composite tobacco filter before the cutting of the composite tobacco filter to detect the presence or absence of defects of the composite tobacco filter or each tobacco filter of the composite tobacco filter cut after the cutting of the composite tobacco filter By detecting the mutual length ratio of the detection method in the manner of detecting the presence or absence of the failure of the composite cigarette filter and transmits the detected result to the controller (800).

When the color of the composite cigarette filter and the number of times of passage of the color are detected before the cutting of the composite cigarette filter, the sensor 700 may be provided in plural.

The sensor 700 is installed in front of the filter cutting unit 50 on the filter transfer unit 20 and detects the color of the combined tobacco filter continuously passing through the sensing area of the sensor 700 and detects the number of times the same color passes. Proximity sensor 710 for detecting the distance between the filter cutting unit 50 and the optical sensor is installed adjacent to the sensor and the filter cutting unit 50 using a bracket 720, for example, the number of rotations of the drive unit 30 It may be provided as a distance recognition sensor 730 to recognize the movement distance of the filter transfer unit 20.

The optical sensor may be provided as a photosensor, and the distance recognition sensor 730 may be provided as a rotary encoder.

The photo sensor is a kind of sensor that detects a preset color. For example, a black part of the tobacco filter containing carbon powder among the tobacco filters of the composite cigarette filter detects the color of the composite cigarette filter that passes continuously. The number of passes through the cigarette filter of the same color is detected.

The control unit 800 receives the results detected from the optical sensor, the proximity sensor 710 and the distance recognition sensor 730, and drives the shifting motor 420 according to the detected results to prevent defects of the composite tobacco filter.

For example, the distance between the filter cutting unit 50 and the optical sensor is detected by the proximity sensor 730, and the moving distance of the filter transfer unit 20 is determined by the distance recognition sensor 730 according to the rotation speed of the driving unit 30. When detecting, it is possible to know the time that the composite tobacco filter passing through the detection region of the optical sensor reaches the filter cutting unit 50 and is cut.

At this time, since each tobacco filter of the composite cigarette filter is supplied with the same length, when the number of times the filter of the same color is passed by the optical sensor, it is possible to know the distance that the composite cigarette filter moves.

Thus, the standard cigarette which has passed through the detection region of the optical sensor reaches the filter cutting unit 50 and is moved in the cutting time, and converted into the number of times that the cigarette filter of the same color sensed by the optical sensor passes. The actual travel distance of the composite cigarette filter should be the same so that the defect of the composite cigarette filter does not occur.

For example, the reference time for the composite cigarette filter passing through the detection area of the optical sensor to reach the filter cutting unit 50 is calculated and set in the control unit 800, and the composite cigarette filter reaches the filter cutting unit 50. Set the number of times the cigarette filter of the same color detected by the light sensor passes during the reference time to be cut, so that the actual number of passes of the cigarette filter of the same color detected by the light sensor differs from the reference count. Since a defect of the composite tobacco filter occurs, the shift motor 420 is driven to adjust the speed of the filter transfer unit 20 so that the actual number of times matches the reference number of times, thereby preventing the occurrence of defective products.

In addition, when the composite tobacco filter is cut, the color of the cigarette filter detected by the optical sensor is preset to the controller 800, and the shift motor 420 is driven even when the actual detected color is different from the preset reference color. By adjusting the speed of the filter transfer unit 20, the reference color is matched with the color actually detected to prevent the occurrence of defective products.

In addition, in the case of detecting the mutual length ratio of each tobacco filter of the composite tobacco filter cut after the cutting of the composite tobacco filter, the sensor is installed after the filter cutting unit 50 on the filter transfer unit 20, It may be provided as an optical sensor for detecting the mutual length ratio of the cigarette filter.

When the cut composite tobacco filter is transferred to the sensing area of the optical sensor, the optical sensor determines whether the reference mutual length ratio of each tobacco filter of the preset composite tobacco filter is equal to the mutual length ratio of the cut composite tobacco filter. If it is not the same, the shift motor 420 is driven to adjust the speed of the filter transfer unit 20 so that the reference mutual length ratio and the actual mutual length ratio coincide with each other to prevent the occurrence of defective products.

In addition, when the composite tobacco filter cut after the filter cut part 50 on the filter transfer part 20 is defective, a discharge device 1000 for discharging it is installed.

Among the composite tobacco filters cut by the discharge device 1000 are classified as good or defective products, poor composite tobacco filter is removed on the filter transfer unit 20 by the discharge device.

The control unit 800 drives the shifting motor 420 of the filter cutting interval adjusting device to change the speed of the filter transfer unit 20 when the cutting part of the composite cigarette filter is cut at the A part or the C part instead of the B part.

In the state where the driving unit 30 is being driven, the filter transfer unit 20 is operated only by the driving force of the driving unit 30.

At this time, when the composite cigarette filter is cut to other parts (for example, A part or C part) other than the B part and the variable speed motor 420 is driven by the controller 800, the worm shaft 400 rotates. The worm shaft 400 and the worm 410 connected to the shaft rotates to rotate the shift control unit 200.

When the shift control unit 200 rotates, the rotation shaft 300 connected to the shift control unit 200 is also rotated so that the rotation speed of the driving shaft 100 that is rotating is decelerated or accelerated according to the rotation direction of the shift motor 420. do.

When the rotational speed of the drive shaft 100 is decelerated or accelerated, the feed speed of the filter feeder 20 is also reduced or accelerated to adjust the cutting position of the composite tobacco filter.

The composite tobacco filter manufacturing apparatus equipped with the filter cutting interval adjusting device according to the present invention generates a defective product by adjusting the cutting position of the composite tobacco filter without stopping the filter transfer unit 20 or reducing the feed rate of the filter transfer unit 20. Since the production capacity of the composite cigarette filter is increased, and the sensor 700 automatically detects the cutting position of the composite cigarette filter and adjusts the cutting position of the composite cigarette filter, an excellent effect of remarkably reducing the incidence of defective products. There is.
