Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaner for cleaning tubes used for filling toothpaste and the like.

As this type of tube cleaner, one shown in the FivJi diagram is known. In this system, an intake pipe 2 connected to a suction pump 1 is inserted into a tube 3 supported in an inverted configuration, and dust inside the tube is sucked up through a suction port 2G at the lower end of the intake pipe. The disadvantage is that the noise associated with the suction is very loud, and if there are foreign objects other than dust, such as bolts, nands, pins, new moons, etc. inside the tube, it cannot be detected and discharged. was there.

The present invention aims to provide a chain cooler that makes little noise during cleaning and that can easily detect foreign matter as described above inside the tube. Above the holder for supporting the tube to be opened in an inverted state, there is provided a cylindrical cover to be fitted over the tube, and a dust removal ventilation pipe supported in the center of the cover so as to be movable up and down. , the cover is supported by an appropriate support device so as to be movable up and down, and a spring is provided between the ventilation pipe and the cover to bias the ventilation pipe downward; It is characterized by the installation of a microswitch that detects a stroke misalignment with the cover.

To explain the embodiment of the present invention in detail with reference to the drawings, in FIG. The placement part 10α of the tube 10 is opened.

Above the holder 11, a cylindrical cover 13 that can be fitted onto the tube 10 via an air flow path FJ12 is disposed so as to be movable up and down supported by an appropriate support device.
A vent pipe 14 for supplying compressed air inserted into the tube 10 is supported in the center of the tube 3 .

The ventilation pipe 14 has a nozzle 15 at its lower end for spouting compressed air into the tube IO, and a compressed air source 18 such as a compressor is connected to its upper end via a solenoid valve 16 and a filter 17. Then, the ventilation 't14 is inserted into the central part of the p-bar U so as to be movable up and down, and the ventilation pipe 14 is inserted between the spring seat 19 provided on the ventilation pipe 14 and the protrusion 13G of the force (-). Loaded with a spring that biases the
Due to the bias of this spring, the micro-switch 4 mounted on the vent pipe 14 is brought into pressure contact with the protrusion 13 with a force z<-13. The nozzle 15 is a spout provided at the head of the tube 100 as shown! Oh.

The inner diameter of the nozzle 15 is also small, and the nozzle 15 is connected to the spout 10.
By inserting it into the injection tube [], the dust accumulated in the injection chamber [ ] can be reliably discharged.

In addition, a large-diameter pocket part n is formed at the lower end of the cover 13, and an opening is opened in the pocket part B to remove dust loss for sucking and discharging the dust discharged from the tube 10 with air by a dust collector. I'm letting you do it.

The pocket part n not only relieves the suction bow 1 force acting on the tube 10, but also prevents the tube from blocking the dust exhaust port when the tube is sucked toward the dust exhaust mouth side by the corpse suction force. It is something to do.

When cleaning the tube with the cleaner having the above configuration, lower the cover 13 using the support device and fit it onto the tube 10 as shown in FIG. By switching the valve 16, compressed air from the air source 18 is blown through the vent pipe 14 and into the tube 10 from the nozzle 15. The dust inside the tube is blown away by this jet of compressed air and discharged into the cover 13 from the opening holder 106,
The dust loss is sucked and discharged together with air to the dust collection equipment.

The compressed air may be ejected after the cover 13 and the vent pipe 14 reach the end of the downward stroke, but it may also be ejected at the same time as the start of the downward stroke or in the middle thereof.

The dust inside the tube is removed by blowing out compressed air as described above, but thick objects such as bolts, nuts, bottles, pieces of paper, etc. that cannot be removed by compressed air are detected in the following manner. That is, when the nozzle 5 comes into contact with W'rlp in the tube 10 during the downward stroke, the ventilation pipe 14 stops, but the cover 13 resists the biasing force of the spring and continues the predetermined stroke. Since it descends to the end, a stroke shift occurs between them, and the protrusion 13α of the cover is separated from the microswitch 21. Due to this separation, the microswitch 21 is switched and a foreign object detection signal is activated, so that the presence of a foreign object in the tube can be known from this detection signal.

The above-mentioned embodiment employs a method in which compressed air is blown into the tube through the ventilation pipe 14, but conversely, it is also possible to configure the lower end of the ventilation pipe to be used as a suction port to suck out dust inside the tube. In this case, it is not necessary to provide the pocket part n and the pocket part in the cover 13.

As described above, according to the tube cleaner according to the present invention, since the force/(- is fitted onto the tube when cleaning the tube, the generation of noise accompanying cleaning can be suppressed, and the cover and Since the vent tube is movable relative to the tube and the deviation in their strokes is detected by a microswitch, the presence of foreign matter in the tube can be easily detected from the deviation in strokes.
