Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tipping paper adhesion detection device, and more specifically, to a tipping paper adhesion detection device, which is used in a tipping paper wrapping device for manufacturing a filter cigarette with a rolling hand for winding tipping paper. This paper relates to a chip paper adhesion detection device that detects chip paper adhesion to a surface. [Conventional technology To make a cigarette with a co-filter, a tip paper coated with an adhesive on one side is connected to a filter tip by a rolling drum and a rolling hand provided to form a passage between the rolling drum and the rolling drum. It is manufactured by wrapping it around the ends of two adjacent cigarettes to form a single rod-shaped product, and then cutting the rod-shaped product in the center to make two filter-equipped cigarettes. By the way, when manufacturing cigarettes with filters, defective products may occur due to various reasons, such as poor wrapping of tip paper. For example, defective products may occur due to chipping paper adhering to the surface of the rolling hand. R regularly inspected the rolling hand and detected the presence of tip paper. [Lesson I that the invention solves and attempts! ! ]however,
When a worker inspects the rolling hand, the machine must be stopped. Therefore, frequent inspections will reduce production efficiency and take more time. Conversely, if the number of inspections is reduced, there is a risk that the number of defective products due to chip paper adhesion will increase, and if the number of defective products increases, it will take more effort to eliminate the defective products. In any case, conventionally, even if chip paper adhered to the rolling hand, it could not be detected at the same time as the adhesion, and the process was carried out afterward. Therefore, there has been a need for a chip paper adhesion detection device that does not reduce production efficiency, does not require much effort, and can reduce the number of defective products caused by chip paper adhesion. [Means for Solving the Problems] In order to solve the above problems, the chip paper adhesion detection device of the present invention has a mouth-ring hand in which an air blowing hole is formed in the contact surface with the chip paper, and a rolling hand. The present invention includes an air supply means, a pressure detection means having a converter for converting a change in supply air pressure into a change in an electric signal, and a comparator for determining the presence or absence of adhesion, and detects adhesion of tip paper based on a change in pressure. The gist is: [Operation] According to the present invention, the air supplied to the rolling hand by the air supply means is blown out from the air blowing hole formed in the contact surface of the rolling hand.

Here, the supplied air pressure is converted into a change in electrical signal by a converter, and then compared with a predetermined value by a comparator to determine whether or not there is adhesion, and the adhesion of tip paper is detected based on the pressure change.

[Implementation @] An embodiment of the tip paper adhesion detection device of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic diagram of the entire chip paper adhesion detection device of the present invention. The tip paper adhesion detection device of the present invention includes a rolling hand 1, an air supply means to the mouth-ring hand 1, and an air pressure detection means. The mouth-ringing hand 1 is provided at a distance slightly shorter than the diameter of the cigarette a from the surface of the rolling drum 2 so as to form a substantially parallel path with the rolling drum 2, as shown in FIGS. 2 and 3. As shown in FIG.
2 is taking shape.

In FIG. 1, 3 is a protrusion for supporting tobacco provided on the surface of the rolling drum, 4 is a transfer guide provided along the outer circumferential surface of the rolling drum 2 to prevent the cigarette from falling, and 5 is 2
A transfer drum supplies a stick-like object with a chip paper end glued to the butt of a book of tobacco and a filter chip to the rolling drum 2, and 6 is a quality checker installed adjacent to the rolling drum 2.・Showing the inspection drum for soku. As shown in FIGS. 2 and 3, the rolling hand 1 has an air passage 13 formed inside, and two air blowing holes 12 with a diameter of about 1 mm formed on the contact surface 11 with the filter chip piece. An air suction hole 14 is formed in the upper part of the opposite side of the contact surface 11.

The positional dimensions of the air blowing holes 12 are as follows: In the longitudinal direction of the rolling hand 1, the opening is 10III1±3 from the edge end face of the contact surface 11 with the filter chip piece, and in the lateral direction, the opening is 10III1±3 from the edge end face of the contact surface 11 with the filter chip piece, and in the lateral direction, it is open in the width direction depending on the width of the chip paper. From the center position of the surface 11, it is divided into 10±3lIIll.

Note that the detection range can be expanded by forming a large number (for example, about 10) of air blowing holes 12 over a wide area of the contact surface 11.

The air supply means includes a pressure regulating tank that is an air reservoir for supplying stable air, a low pressure reducing valve that reduces the pressure from 1 kg/cm2 to 1000 mm 820 or less for supplying low pressure air to the rolling hand 1, and equipment pressure (6 kg/cm
2) to about 1 kg/c+*2, one end is connected to the rolling hand 1 via a three-pronged pipe 7, and the other end is connected to air supply equipment. ing. The air supply means supplies air so that low-pressure blow (test air) is constantly blown out from the air outlet 12 of the rolling hand 1. The test air pressure is 10 to 1
0 0 + amH20 or so, preferably 3 0
mmH20±1 0 ++uw}120.

On the other hand, the pressure detection means consists of the rolling hand l and the three-pronged pipe 7.
A switchboard that converts pressure into electrical signals. A comparator that determines whether the adhesion is scorched. In addition to the display section that displays pressure using a lamp or meter, it also has a control circuit that amplifies the signal and sets the judgment level. In addition, the pressure detection means is a semiconductor pressure comparison device that supplies an applied voltage to a pressure transducer that forms a balanced circuit using the viezo resistance effect of a semiconductor on a diaphragm, and converts a change in pressure into an electrical signal as a change in bridge balance. instrument, calibration C
It may also include an AI voltage, an amplifier circuit, a comparison circuit, a relay, a lamp, etc. (see Figure 4).

As shown in Figure 4, it can also be used in place of a manometer by displaying the pressure digitally. Furthermore, although not shown, the comparator and the power supply of the machine can be linked to immediately stop the machine when a pressure change due to adhesion of tip paper is detected. Next, the operation of the chip paper adhesion detection device according to the present invention will be explained.

First, high-pressure air supplied from the equipment is reduced in pressure by a high-pressure reducing valve of the air supply means, and further reduced in pressure by a low-pressure reducing valve, and then stored in a pressure regulating tank and constantly supplied to the rolling hand 1.

The air supplied to the rolling hand is passed through the air passage 13.
The air is constantly blown out from the air blowing hole 12 formed in the contact surface 11 with the chip-baber. At this time, the air supply pressure is converted into an electrical signal by the pressure converter of the pressure detection means, and is displayed by a display unit such as a lamp via a comparator. Wrapping of the chipping paper around the rod-shaped object is performed by a rolling hand 1 and a mouth-ring drum 2 from which low-pressure air is blown out from air blowing holes 12 in the contact surface 11 with the chipping paper.

Here, when winding is performed normally, the air blowing hole 12 of the rolling hand 1 is temporarily blocked by the chip paper, and the air supply pressure also changes temporarily, but it is lower than the predetermined setting value. It will never rise.

However, when the chip paper adheres to the rolling hand 1, the air blowing hole 12 of the rolling hand 1 is blocked and the air supply pressure rises above the set value.

Therefore, if the air supply pressure rises above the set value,
This means that the chip paper is attached to rolling hand 1. In this way, depending on the change in the air supply pressure, the presence or absence of chip paper adhesion to the rolling hand 1 is detected at the same time as the adhesion. If tip paper is detected, the operator stops the equipment. Furthermore, if the power supply of the comparator and machine is moved, the equipment will automatically stop if chipping paper is detected, saving the worker the trouble of constantly monitoring the equipment. Labor saving is achieved. For products manufactured by a chip paper winding device equipped with a chip paper adhesion detection device as described above, the detection device has no effect on the quality of the rolled product. [Effects of the Invention] According to the present invention, it is possible to detect the presence or absence of tip paper adhesion to the rolling hand almost simultaneously with the adhesion of the tip paper by changing the air supply pressure. Therefore, it is possible to quickly respond to chip paper adhesion, detect it reliably, prevent a large number of defective products, and eliminate the trouble of eliminating defective products. Additionally, there is no need for periodic inspections to check for chip paper adhesion, and there is no need to frequently stop the machine for inspections, so production efficiency does not decrease and labor can be saved.
