摘要： PURPOSE:To provide a detector surely and quickly detecting a yarn breakage even when this occurs in a single fiber. CONSTITUTION:Each yarn F is wound on a tubular rubber layer 3 by the rotations of each bobbin #1-#20 of an under net braider 8 to form under layer 4. The yarn breakage detector 11 is provided with a laser beam sensor 12 consisting of a light projector 16 and a light receiver 17, an amplifier 13, a digital meter relay 14 and a controller 15. When each yarn F passes through the space between the light projector 16 and the light receiver 17 of the laser beam sensor 12, the laser beam which is not reflected on the yarn is received by the light receiver 17. A timing signal and a yarn width signal proportional to the width of yarn F are output. Depending on the both signals, it is determined whether the yarn F has the width of larger than the specified size. If NG signals for an identical bobbin continues for specified times, it is decided that yarn is broken. When yarn F is clung itself and becomes narrow for a short period, it is not judged as yarn breakage.

摘要： PURPOSE:To secure airtightness between a liquid leakage inspecting device for brake hose, etc., and the mouthpiece of a hose when the device is press-contacted with the mouthpiece and an inspection fluid is led into the hose so as to prevent wrong discrimination by providing a means which applies tension to the hose in the device. CONSTITUTION:A brake hose W is suspended by means of the suspending click 13 of a supporting base 13 and the base 8 is moved to an inspecting position side by energizing a tension applying cylinder 11. As a result, the base 8 comes to the inspecting position. When the base 8 comes to the position, the hose W becomes almost straight due to the tension applied by the energized cylinder 11. Therefore, when a fluid leading port 5 comes into contact with the mouthpiece of the hose W, both of them are tightly adhered to each other. Then the rod 4a of a cylinder 4 for sealing protrudes and a fluid leading means 5 moves toward the base 8 holding the mouthpiece Wa. As a result, an airtight condition is maintained between the means 5 and mouthpiece Wa and, when a liquid is led into the hose for inspection, no liquid leakage occurs due to wrong connection. The connected state can be discriminated by means of a sensor 12.

摘要： PURPOSE:To prevent wasteful use of time so as to prevent a decline in inspection accuracy following the wasteful time by immediately stopping a fluid leakage inspec tion when a large amount of air leakage occurs caused by wrong setting of an object to be measured, etc. CONSTITUTION:After all valves are closed and a reference tank 12 is filled up with air pressurized to about an inspection pressure (14kg/cm ), an object to be inspected (brake hose W, etc.) is put between communicating tubes 1 and both ends of the hose W are closed by means of a cylinder 2 for sealing actuated by means of a control circuit 16. Then air pressurized to a prescribed pressure is supplied from an air supplying source 6 into the hose W through one of the tubes 1 through a by-pass tube 13 and the inside of the hose W is maintained at the inspection pressure. After the inside of the hose W is maintained at the inspection pressure, the tank 12 is communicated with the hose W by opening a solenoid valve 7 and the flow rate is measured with a flow meter 8. When a large amount of air flows out from the tank 12, the connection is discriminated as imperfect and the inspection is stopped. When the flow rate is small, a solenoid valve 14 is closed and the acceptance of the hose W is discriminated from the amount of the flow rate by measuring the flow rate.

摘要： PURPOSE:To reduce the burden of an operator by holding a cover of a casing of a main body in the closed state by means of a holding member against an urging means, and releasing the holding when the processing of the work is finished. CONSTITUTION:A brake hose W is placed on a work supporting member 4. A cover 2 is closed against the urging force of an opening spring 11. A magnet 9 attracts a suction face 8. While the cover 2 is held in the closed state, a leak in a casing 1 is inspected. A knock-out cylinder 5 is driven at the final process to project a rod 5a. In consequence, the brake hose W is pushed slantwise upward by a discharge manipulating face 6b in accordance with the upward movement of a releasing means 6, and dropped and discharged from on the supporting member 4. An operating bar 7 is pushed up by a manipulating face 6a and the suction face 8 of the cover 2 is separated from the magnet 9. Therefore, the cover 2 is opened by the urging force of the spring 11. Since the cover 2 is automatically opened after the work is completely processed, the burden of the operator is reduced.

摘要： PURPOSE:To enable inspection of a large number of workpieces with high precision and in a short time and to enable classification of the inspected workpieces into the conforming and nonconforming articles by arranging supporting and holding elements and first collecting elements with a distance equal to a space between right and left clamps set between them respectively. CONSTITUTION:Supporting and holding elements 56, 57 and first collecting elements 60, 61 are arranged with a distance equal to a space between right and left clamps 43 and 44 set between them respectively. When one clamp 43 is disposed at a position of supply, therefore, the other clamp 44 is disposed at a position of inspection, while the clamp 44 is disposed at a position of collection when one clamp 43 is disposed at the position of inspection. Accordingly, the two clamps 43 and 44 can carry a pair of workpieces to subsequent processes simultaneously and efficiently respectively with one stroke of a carriage 33. Since the first collecting elements 60, 61 and a second collecting element 64 are provided, in addition, it is possible to classify inspected workpieces into good and bad ones and to collect them in an orderly manner.
