[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cotton wrapping device for wrapping the tip of a medical swab used for dentistry, otolaryngology, surgery and the like.

[0002]

2. Description of the Related Art A medical swab used for dentistry, otolaryngology, surgery, etc. is a swab made of a rectangular corrosion-resistant metal wire having a width of about 0.3 to 0.4 mm and a total length of about 50 mm at the tip of a holder. Although a cotton swab is used, the cotton swab is conventionally wound around a cotton swab by operating a finger wearing gloves in order to avoid adhesion of various bacteria. However, this conventional wrapping means has a problem in that the work efficiency is poor due to finger operation using gloves, and the finish of the wrapped cotton swab is irregular depending on the person and lacks workability and labor saving. At present, there has not been proposed a simple and effective cotton wrapping device that automatically and mechanically eliminates the above-mentioned cotton wrapping operation.

[0003]

[Problems to be solved by the present invention] As means for solving the above-mentioned conventional problems, a simple mechanical winding mechanism and a labor-saving device by automatic operation, uniform finish accuracy, and sanitary The challenge was to be quick.

[0004]

As means for achieving the above object, there is provided a first feeder in which a roll cotton mounting portion and a roll cotton sheet are sandwiched between upper and lower rollers provided at appropriate intervals and pulled out. A roller and a second feed roller unit, a cotton sheet cutter provided between the first feed roller and the second feed roller, an upper and lower belt unit for transferring the cut cotton sheet and elastically pressing the same, A swab mounting portion for rotating a swab attached to the cut cotton pressed between the upper and lower belts,
A medical device comprising the above components and a control unit, a sterilization lamp, etc., a switch, an indicator lamp, an operation unit such as a cotton swab insertion unit, an automatic display unit provided on a body surface, and a container box operated to be connected thereto. The present invention relates to an apparatus for automatically winding cotton swabs.

[0005]

When the switch of the container box is started by inserting the cotton sheet in the first feed roller in advance, the cotton sheet of the movable cotton roll reaches the interlocked second feed roller and is drawn out to a predetermined length. Next, the upper and lower cutters between the feed rollers are moved to cut the cotton sheet, transferred to a belt interlocking with the second feed roller, the cotton sheet is set at a fixed position on the lower belt, and then the cotton swab inserted from the container box is moved. If it touches the cut cotton, the sensor moves the upper belt down onto the cut cotton and lightly oppresses the swab. Next, the swab is rotated by the swivel roll and the push solenoid of the swivel holder swivel unit, and the swab is wrapped around the cotton sheet at the tip of the swab. Pull out. Then, by repeatedly inserting the swab, each part in the body is controlled to operate intermittently, and the cotton wrapping around the swab is repeated. Adjustment of the wrapping time and the length of the cotton sheet is performed by adjusting each display section of the container box.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Reference numeral 11 shown in FIG. 1 is a swab, which comprises a base holder 11a, a swab wire body 11b at the tip of the holder, an intermediate round shaft 11c, and a sensor unit 11d. The holder is formed in a hexagonal shape so as to be easy to hold, and the cotton swab wire 11b is a 0.3-0.4 mm square cotton swab made of a metal having high elasticity. Reference numeral 11c is a thin shaft formed into a round bar by the rotating portion. 11d is a rotation sensor of the holder. FIG. 2 is a perspective view of a winding device in which a cut cotton cc is set diagonally as shown in a plan view 3 on the tip 11b of a cotton swab, and as shown in FIG. It is. 2 and 3, reference numeral 12 denotes a roll of sterilized and defatted roll cotton c, reference numeral 13 denotes a roll shaft, and roll cotton c denotes a roll obtained by winding cotton into a sheet. Reference numeral 14 denotes a first feed roller provided in the direction in which the cotton swabs are pulled out.
5, a small motor 16 is attached, and a roller 14 'is driven. Reference numeral 17 denotes a second feed roller for drawing the sheet cotton c drawn from the first feed roller to a predetermined length, reference numeral 18 denotes a main driving shaft thereof, and reference numeral 19 denotes a motor. 17 'is a driven roller. Reference numeral 20 denotes a timing belt wound around the vertical axis of the first feed roller 14 and the vertical axis of the second feed roller 17.
Reference numeral 21 denotes a cutter movable by a solenoid (not shown) for cutting the sheet cotton c drawn from the first feed roller 14 and the second feed roller 17, and winds the sheet cotton drawn and stretched between the rollers onto the cotton swab 1. The cutter 21 is operated to cut the sheet cotton into the cut cotton cc having a fixed length and width when adjusted so as to be cut to the attached width, and when the second feed roller is nipped and stretched.

Reference numeral 22 denotes an upper belt of the belt portion wound around the second feed roller 17, and reference numeral 23 denotes a lower belt portion. 2
4 is the other end roller of the upper belt, 25 is the roller shaft, 26 is the other end roller of the lower belt, and 2 is the roller shaft of the upper belt 22.
5 is a screw shaft 27 which is connected to the motor 41 and rotates.
The upper belt 2
2 is provided on the lower belt 23 so as to be elastically pressed or opened. 29 is a push sponge attached between the upper and lower belts. Reference numeral 30 denotes a rotating roll for rotating the swab 11 by contacting the round shaft 11c of the swab, and is attached to the rotating shaft 31.
32 is a motor. Reference numeral 33 denotes a rotating roll of a pushing solenoid 34, which comes into contact with the round shaft 11c and assists the rotation of the cotton swab 11. The cotton swab 11b at the tip of the holder protrudes so as to stick on the cut cotton cc transferred by the belt, contacts the cut cotton as shown in FIGS. 2 and 3, and when the upper belt is elastically pressed on the lower belt. As shown in FIG. 4, the swab is wound around the cut surface cc by frictional rotation of the swab.
