At this time, if there is a pinhole in the glove, impurities are mixed into the product, so an inspection is made as to whether or not there is a pinhole before use. For inspection of gloves, for example, a glove insertion port is closed by a closing portion provided with an attachment portion ring to which a glove is attached, an O-ring is fitted on the glove attached to the attachment portion ring, and the glove is placed in the opening of the partition member. After inserting and sealing, air is injected into the gloves to check whether the pressure in the gloves drops.

JP 7-151635 A

  However, this method has a problem that the O-ring has to be fitted on the glove attached to the attaching portion ring, and the attaching operation of the glove is troublesome and takes time. In particular, this attachment work is more difficult because it is carried out with gloves to prevent contamination of impurities, and the work takes 30 minutes or more. Further, after the inspection is finished, it is necessary to remove the glove from the attachment ring without taking it out from the opening of the partition member. However, since there is an O-ring, there is a problem that this removal work is also difficult.

  The present invention has been made based on such a problem, and provides a leak tester and a glove inspection method capable of easily attaching and removing gloves and easily inspecting pinholes. Objective.

  In Patent Document 1, an ultrasonic detector is installed at a position facing a surface to be inspected in a method for detecting the presence or absence of a pinhole by enclosing and inflating a gas in a glove and detecting the leakage. And an inspection method for checking the presence or absence of leaked airflow is described. However, the specific configuration and the inspection method differ from the present invention.

  The leak tester of the present invention inspects whether or not there is a pinhole in a glove when a gloved hand is inserted through an opening provided in the partition member in a space partitioned by the partition member. A closing means for closing the insertion port of the glove, a first injection means for injecting gas into the glove, and an outer peripheral surface of the attachment portion. An expansion / contraction part provided inside and having a fluid flow path, at least a part of the surface of which is made of a stretchable material, and a second injection means for injecting fluid into the flow path of the expansion / contraction part. The expansion / contraction part is expanded to the outside by injecting fluid, and the glove can be brought into close contact with the partition member.

  The glove inspection method of the present invention determines whether or not a glove has a pinhole when working with a gloved hand inserted through an opening provided in the partition member in a space partitioned by the partition member. Using the leak tester of the present invention, attach a glove insertion port to the leak tester mounting part, insert the glove into the opening of the partition member, and inject fluid into the flow path of the expansion and contraction part. The expansion / contraction part is expanded outward, the glove is brought into close contact with the partition member, and then the presence or absence of a pinhole is determined by injecting gas into the glove.

  According to the present invention, since the expansion / contraction part is provided on the outer peripheral surface of the attachment part and the fluid is injected into the flow path of the expansion / contraction part, the glove can be brought into close contact with the partition member. There is no need to fit a ring and gloves can be easily attached. Moreover, when removing, the fluid is discharged from the flow path of the expansion / contraction part and contracted, so that only the leak tester can be easily removed without taking out the glove from the opening of the partition member. Thus, gloves can be easily attached and removed, and pinholes can be easily inspected.

  Further, the first injection means is configured to be able to inject gas into the glove by stepping on the foot with a foot, and the second injection means is configured to flow through the pedal with the foot. If it is configured so that fluid can be injected into the inside, the operation can be performed by stepping on the pedal with the foot while supporting the closing means by hand. Therefore, the operation can be performed easily.

It is a figure showing the structure of the leak tester which concerns on one embodiment of this invention. It is an end elevation along the II-II line of the leak tester shown in FIG. FIG. 3 is an end view taken along line III-III of the leak tester shown in FIG. 1. It is a figure showing the use condition of the leak tester shown in FIG. It is another figure showing the use condition of the leak tester shown in FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration of a leak tester 10 according to an embodiment of the present invention. FIG. 2 shows the end surface structure along the line II-II shown in FIG. 1, and FIG. 3 shows the end surface structure along the line III-III shown in FIG. 4 shows a state where the glove 20 is attached to the leak tester 10 shown in FIG. 1, and FIG. 5 shows a state where the glove 20 attached to the leak tester 10 is inserted into the opening 31 of the partition member 30. Is.

  The leak tester 10 has a pinhole in the glove 20 when the glove 20 is inserted and operated in a space partitioned by the partition member 30 through the opening 31 provided in the partition member 30. It is to check whether or not. The glove 20 to be inspected is made of, for example, synthetic resin or rubber. The leak tester 10 is used by attaching a glove 20 to be inspected, for example, and includes a closing member 11 that is a closing means for closing an insertion port 21 of the glove 20. The closing member 11 is made of plastic, for example, and has a disc-shaped lid portion 11 </ b> A that closes the insertion port 21 of the glove 20.

  One outer peripheral portion in the thickness direction of the lid portion 11A, specifically, an outer peripheral portion on the opposite side to the side on which the gloves 20 are inserted, for example, a collar portion that protrudes so as to enlarge the lid portion 11A in the radial direction 11B is formed. The outer peripheral portion on the other side in the thickness direction of the lid portion 11A than the collar portion 11B is, for example, an attachment portion 11C to which the insertion port 21 of the glove 20 is attached. The diameter of the attachment portion 11 </ b> C is formed smaller than the diameter of the opening 31 of the partition member 30, and the diameter of the flange portion 11 </ b> B is formed larger than the diameter of the opening 31 of the partition member 30. Thus, when the attachment portion 11C is inserted into the opening 31 of the partition member 30, the flange portion 11C comes into contact with the outer surface of the partition member 30, and the attachment portion 11C can be inserted at a position facing the inner wall of the opening 31. It is like that.

  For example, a through hole 11D is provided in the lid portion 11A so as to penetrate the lid portion 11A in the thickness direction. In the through hole 11D, for example, a first injection means 12 for injecting gas into the glove 20 via a pipe 12A such as a vinyl tube is disposed. The first injection means 12 is configured to send gas into the through hole 11D and inject gas into the glove 20 by, for example, stepping on a pedal with a foot. For example, air is used as the gas injected into the glove 20. The pipe 12A is also provided with first discharge means 13 for discharging the gas injected into the glove 20. The lid 11A is also provided with a pressure measuring means 14 such as a pressure gauge for measuring the pressure in the glove 20 attached to the attaching part 11C.

  An expansion / contraction part 15 having a fluid flow path 15A therein is provided on the outer peripheral surface of the attachment part 11C. For example, at least a part of the surface of the stretchable portion 15 is made of a stretchable material, and when the fluid is injected into the flow path 15 </ b> A, the surface expands outward and enters the opening 31 of the partition member 30. On the other hand, the gloves 20 can be brought into close contact with each other. The expansion / contraction part 15 has, for example, two ridges 15B formed along the circumferential direction of the attachment part 11C, and a flow path 15A is formed between the two ridges 15B. . On the flow path 15A, for example, a covering member 15C made of a stretchable material is disposed so as to span the two protrusions 15B and cover the flow path 15A. The covering member 15C is made of, for example, silicone rubber.

  For example, a communication hole 11E formed in the lid portion 11A communicates with the flow path 15A. In the communication hole 11E, for example, a second injection means 16 for injecting a fluid into the flow path 15A is provided via a pipe 16A such as a vinyl pipe. The second injecting means 16 is configured such that, for example, by stepping on a pedal with a foot, a fluid can be sent into the communication hole 11E and injected into the flow path 15A. For example, air is used as the fluid injected into the flow path 15A. The pipe 16A is also provided with discharge means 17 for discharging the fluid from the flow path 15A.

  The closing member 11 is provided with a pair of handles 18 on one surface in the thickness direction, for example.

  Using this leak tester 10, whether or not there is a pinhole in the glove 20 is inspected as follows. First, for example, as illustrated in FIG. 4, the insertion opening 21 of the glove 20 is attached to the attachment portion 11 </ b> C of the leak tester 10. Next, for example, as shown in FIG. 5, the handle 18 of the leak tester 10 is held with both hands, and the glove 20 attached to the leak tester 10 is inserted into the opening 31 of the partition member 30. At that time, the flange portion 11 </ b> B of the leak tester 10 is brought into contact with the outer surface of the partition member 30, and the stretchable portion 15 is opposed to the inner wall of the opening 31. Subsequently, for example, by stepping on the pedal of the second injection means 16 with a foot, fluid is injected into the flow path 15A of the expansion / contraction part 15, the covering member 15C of the expansion / contraction part 15 is expanded outward, and the expansion / contraction part 15 The glove 20 located outside is brought into close contact with the opening 31.

  After that, for example, by stepping on the pedal of the first injection means 12 with a foot, gas is injected into the glove 20, and the pressure in the glove 20 is set to a predetermined pressure greater than atmospheric pressure. Next, for example, it is left for a predetermined time, and the pressure in the glove 20 is observed by the pressure measuring means 14. As a result, if a pressure drop is observed, it is determined that there is a pinhole, and if no pressure drop is observed, it is determined that there is no pinhole. When there is a pinhole, for example, the gas in the glove 20 is discharged by the first discharge means 13 and the fluid is discharged from the flow path 15A of the expansion / contraction section 15 by the second discharge means 17 to expand / contract the expansion / contraction section. 15 is contracted, and the glove 20 is taken out from the opening 31 while being attached to the attachment portion 11C. When there is no pinhole, for example, the gas in the glove 20 is discharged by the first discharge means 13 and the fluid is discharged from the flow path 15A of the expansion / contraction section 15 by the second discharge means 17 to expand / contract the expansion / contraction section. 15 is shrunk, the glove 20 is removed from the attachment portion 11C, and the leak tester 10 is removed without removing the glove 20 from the opening 31.

  As described above, according to the present embodiment, the expansion / contraction part 15 is provided on the outer peripheral surface of the attachment part 11 </ b> C, and inflated by injecting fluid into the flow path 15 </ b> A of the expansion / contraction part 15. Therefore, it is not necessary to fit an O-ring, and the glove 20 can be easily attached. Further, when removing, by discharging the fluid from the flow path 15A of the expansion / contraction part 15 and contracting, it is possible to easily remove only the leak tester 10 without taking out the glove 20 from the opening 31 of the partition member 30. . Therefore, the gloves 20 can be easily attached and removed, and the pinhole can be easily inspected.

  Further, the first injection means 12 is configured such that gas can be injected into the glove 20 by stepping on the foot with a foot, and the second injection means 16 is formed by stepping on the pedal with a foot. If the fluid can be injected into the flow path 15A, the operation can be performed by stepping on the pedal with the foot while the closing member 11 is supported by the hand. Therefore, the operation can be performed easily.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, each component has been specifically described. However, not all the components may be provided, and other components may be provided.

  It can be used to inspect whether a glove has a pinhole.
