BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glove attaching / detaching device for facilitating attachment / detachment of a glove made of a soft resin such as vinyl or an elastomer.

[0002]

2. Description of the Related Art As a conventional glove attaching / detaching device, for example, one disclosed in JP-A-2-53902 (Japanese Patent Application No. 63-200124) filed by the applicant of the present application is known.

That is, in the glove attaching / detaching device, when the glove is worn on the hand, first, the glove is set in the glove insertion part, the glove insertion part is sucked by a vacuum pump to inflate the glove, and the glove is inflated. By inserting compressed air into the glove insertion part after inserting the glove, the glove is brought into close contact with the hand. In addition, when removing the gloved hand, insert the gloved hand into the glove insertion part, and inflate the glove by sucking inside the gloved insertion part as in the case of wearing above, which makes it easy to move the gloved hand from the glove. It is possible to extract it.

[0004]

However, according to the above-mentioned conventional glove attaching / detaching device, when putting the glove on the hand, the glove inflated inside the glove inserting part is inserted into the glove inserting part and then compressed air such as a compressor is inserted into the glove inserting part. Since the gloves are brought into close contact with the hand by supplying compressed air from the supply source, it is necessary to drive both the vacuum pump and the compressed air supply source during use regardless of whether the gloves are worn or removed. However, there are problems that the operation is complicated, and that noise and power consumption are large.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to wear gloves very easily and quickly, and
It is to reduce noise and save power.

[0006]

In order to solve the above problems, the present invention provides a glove insert portion having an opening edge portion which can be closely engaged with a fitting mouth peripheral edge portion of a glove, and suction to the glove insert portion. In the glove attaching / detaching device having a vacuum pump connected by a piping for air, an air inflow pipe that allows air to flow into the glove insertion portion, and a flow control valve provided in the air inflow pipe, And a vacuum release hole that is communicated with the atmospheric pressure atmosphere side, and a valve body that is biased by a spring so as to be in close contact with the wall surface of the vacuum release hole on the atmospheric pressure atmosphere side,
A push button that is integrally connected to the valve body and protrudes into the glove insertion portion is provided.

[0007]

According to the above construction, when the glove is worn on the hand, the glove is inserted into the glove insertion part, and the periphery of the fitting mouth of the glove is engaged with the opening edge part of the glove insertion part, Inflate the glove body by sucking with a vacuum pump. Here, if a glove in which the fitting edge peripheral part is reinforced in advance with a reinforcing ring is used, the entire glove will not be sucked into the glove insertion part during the suction, and the glove inside and outside the glove generated Due to the pressure difference, the peripheral portion of the fitting opening is brought into close contact with the opening edge portion, which is convenient. The expansion degree of the glove can be appropriately set according to the strength of the glove by adjusting the flow rate of the air flowing into the glove insertion portion from the air inflow pipe by suction with the flow control valve. Then, insert your hand into the inflated glove and then immediately press the push button inside the glove insertion part with this hand to manually open the valve element that was closed due to the negative pressure and spring load inside the glove insertion part. When the valve is opened, the inside of the glove insert will be opened to the atmosphere through the vacuum release hole.
The glove contracts and fits to the hand, and the wearing is completed.

Next, when removing the glove fitted to the hand, the gloved hand is put into the glove insertion part, and the glove insertion part is sucked to inflate the glove, as in the case of the above-mentioned wearing, Pull out your hand and stop the vacuum pump.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the appearance of a glove attaching / detaching device 10 according to an embodiment of the present invention.
Is a pair of left and right glove inserts opened on the upper front surface of the body 11, 14 and 14 are vacuum pumps independently connected to the glove inserts 12 and 12, 15 and 15 are power switches, and 16 is It is a foot pedal that opens and closes a foot switch (not shown).

As shown in FIG. 2, this glove attaching / detaching device 10
The glove 1 to be attached / detached by is made of vinyl, elastomer, or the like, and has a circular inner ring 3a, which is made of PTFE or a lightweight resin material and has a simple radial cross-section, on the fitting edge 2 thereof. A reinforcing ring 3 having a wire diameter larger than that of the inner ring 3a and an outer ring 3b having a substantially C-shaped radial sectional view.
Is fitted, that is, the inner ring 3a is fitted and the peripheral portion 2
The inner periphery of the inner ring 3a by fitting the inner peripheral portion 2 into the inner ring 3a.
The outer peripheral edge portion 2 is reinforced in advance by being wound around the outer ring 3b and fitting the outer ring 3b on the outer side thereof. Then, the opening edge portion 1 at the front end of each glove insertion portion 12
When the glove 1 is inserted into the glove insertion part 12, the glove 3 closely engages with the fitting edge part 2 reinforced by the reinforcing ring 3. Note that the glove 1 is not limited to the illustrated example, and may be, for example, one in which a highly rigid annular body is integrally embedded or bonded to the fitting opening peripheral portion 2.

As shown in FIG. 3, in each glove insertion portion 12, in addition to the suction pipe 17 extending to the vacuum pump 14, the inflow of air into the glove insertion portion 12 at the time of suction by the vacuum pump 14 is performed. Allowable air inflow piping 18
A flow control valve 19 for controlling the amount of air flowing into the glove insertion portion 12 is provided in the middle of the air inflow pipe 18.

As shown in FIGS. 2 to 4, a vacuum releasing hole 20 communicating with the external space A, which is the atmospheric pressure atmosphere side, is formed in the bottom wall at the innermost side of each glove inserting portion 12, and this vacuum releasing is performed. In the valve seat 20a formed at the outer end opening of the hole 20,
The valve body 21 provided with the packing 21a is opposed to the valve body 21 so as to freely come into contact with and separate from the valve body. In addition, the vacuum release hole 2 in each glove insertion portion 12
A push button 22 is provided at a position facing the inner end of 0, and the push button 22 is integrally connected to the valve body 21 via a valve rod 23 loosely inserted in the vacuum release hole 20. .. A spring 24 is contracted between the inner end of the vacuum release hole 20 and the push button 22. The spring 24 allows the push button 22 to project toward the inside of the glove insertion portion 12 and the valve body 21. The packing 21a is always biased so as to be in close contact with the valve seat 20a of the vacuum release hole 20 at all times.

In the attachment / detachment device, the power switch 15 is turned on.
By doing so, the vacuum pumps 14, 14 are driven and the insides of the glove insertion portions 12, 12 are in a suction state. Therefore, when wearing the gloves 1 on the hand, first, the power switch 1
5 is turned on and the vacuum pumps 14, 14 are driven in advance, whereby the glove insertion portion 12, which is in a suction state,
Set gloves 1 to 12. Then, each glove insertion part 12
In the space S ₁ between the inner wall of the glove 1 and the glove 1, the pressure decreases as the fitting edge portion 2 of the glove 1 comes into close contact with the opening edge portion 13 of the glove insertion portion 12, and the pressure of the glove 1 is at atmospheric pressure. by the differential pressure between the internal space S _2, the glove 1, go inflated as shown by a chain line in FIG.

At this time, since the vacuum release hole 20 is closed by the valve body 21, it is sucked by the vacuum pump 14 into the space S ₁ of the glove insertion portion 12 where the pressure becomes low, and the vacuum release hole 20 is externally provided. However, the atmosphere does not flow into the space S ₁ , but on the other hand, the atmosphere flows into the space S ₁ through the air inflow pipe 18, and the space is controlled by adjusting the throttle amount of the flow control valve 19. The internal pressure of S ₁ , in other words, the amount of expansion of the glove 1 can be set appropriately. Further, the fitting edge portion 2 of the glove 1 which is closely engaged with the opening edge portion 13 of the glove insertion portion 12 is reinforced by the reinforcing ring 3, so that the entire glove 1 is completely inside the glove insertion portion 12. It functions as a stopper to prevent the air from being sucked into the space S ₁ , and since the self-sealing action is exerted by the suction, the atmosphere leaks from the space between the fitting edge part 2 and the opening edge part 13 to the space S ₁ . Completely cut off the entry.

Therefore, both hands are put into the gloves 1, 1 which are in engagement with each other in the glove insertion parts 12, 12, but as described above, the glove 1 is in a state of being sufficiently inflated and taut. Therefore, the hand can be inserted very smoothly. Next, as shown in FIG. 4, by pressing the push button 22 in the glove insertion part 12 with the hand (fingertip) put in the glove 1, the negative pressure in the space S ₁ in the glove insertion part 12 and the spring 24 are removed. When the valve body 21 that has been closed due to the urging force is manually opened, the atmosphere in the external space A flows into the glove insertion portion 12 all at once through the vacuum release hole 20, and the space S ₁ is at the atmospheric pressure level. Since the pressure is increased to the vicinity, the glove 1 contracts and sticks to the hand. At the same time, since the suction state (closely engaged state) of the fitting edge portion 2 of the glove 1 with respect to the opening edge portion 13 of the glove insertion portion 12 is released by the pressure increase in the space S ₁ , the glove 1 is worn. The hand can be pulled out from the glove insertion portion 12, and the wearing of the glove 1 is completed.

When the glove 1 fitted in the hand is removed, the glove insertion portion 1 in which both hands are in a suction state while the glove 1 is fitted.
Insert into 2,12. Then, the opening of each glove insertion portion 12 is closed by the engagement with the fitting opening peripheral portion 2 of the glove 1,
As in the case of the above-mentioned wearing, the glove 1 swells. Therefore, a gap is created between the glove 1 and the skin of the hand, and the hand can be pulled out of the glove 1 without any resistance. After that, if the vacuum pump 14 is stopped by turning off the power switch 15, the pressure of the space S ₁ in the glove insertion portions 12, 12 rises due to the inflow of the air from the air inflow pipe 18, The inflated glove 1 contracts and shrinks. At the same time, by the compressed air, the fitting edge part 2 of the glove 1 with respect to the opening edge part 13 of the glove insertion part 12 is
Since the suctioned state (closely engaged state) of the glove 1 is released,
Can be easily taken out from the glove insertion portion 12.

As described above, according to the present embodiment, it is possible to attach and detach the gloves 1 without touching the surface of the gloves 1 with bare hands. And the glove insertion part 12
Since a pair of right and left are provided, the gloves 1 can be attached and detached at the same time with both hands. In addition, the fitting edge portion 2 of the glove 1
When the state of close contact between the glove insert portion 12 and the opening edge portion 13 of the glove insert portion 12 is incomplete, the glove 1 does not swell sufficiently due to air leak into the glove insert portion 12, but the left and right glove insert portions 12 are not inflated. , 12 are independent vacuum pumps 1
The glove insertion part 1 is for example one of the glove insertion parts because it is sucked by 4, 4 and is structured so that there is no mutual interference of the suction force.
Even if the atmosphere leaks as described above in 2, the suction force on the other side is not affected at all. Needless to say, if the fitting edge portion 2 is slightly moved to correct the engagement state with the opening edge portion 13, it is possible to easily eliminate the air leakage.

Next, FIG. 5 schematically shows a part of piping as another embodiment of the glove attaching / detaching device according to the present invention. This embodiment has a tear detection mechanism in the structure of the previous embodiment for the purpose of preventing the gloves 1 from being unknowingly worn when a part of the gloves 1 is damaged. FIG. 6 shows an electric circuit diagram of the detection mechanism added.

That is, in FIG. 5, reference numeral 25 is a pressure sensor section 26 extending from the glove insertion section 12 to the vacuum pump 14 and provided in the suction pipe 17, and operating by sensing the pressure in the glove insertion section 12. A low-voltage side contact a ₁ which works in conjunction with the pressure sensor unit 26 and which conducts when the pressure inside the glove insert section 12 decreases to a predetermined low pressure value, and the pressure increases toward the atmospheric pressure level and reaches a predetermined high pressure value. This is a pressure switch having a high-voltage side contact a ₂ which is brought into conduction at the time. Further, 27 is the pressure sensor unit 2 in the suction pipe 17.
6 is a solenoid valve for shutting off the suction force, which simultaneously opens and closes the connection portion with 6 and the vacuum pump 14 and the air inflow pipe 18.

In FIG. 6, b ₁ and b ₂ are reset switches that open when the foot pedal 16 (see FIG. 1) is depressed, and 28 is energized via the high-voltage side contact a ₁ and the reset switch b _1. , A self-holding relay having contacts c ₁ , c ₂ , c ₃ . Reference numeral 29 is a timer relay that is energized at the same timing as the energization of the self-holding relay 28, and the time-delay contacts d ₁ and d that are closed only for a predetermined count time.
Have _two . The solenoid 27a of the solenoid valve 27 has a contact c _{2 of} a relay 28 and a timed contact d of a timer relay 29.
Energized through ₁ . Reference numeral 30 denotes a self-holding relay that is energized via a contact c _{3 of the} relay 28, a high-voltage side contact a ₂ of the pressure switch 25, and a timed contact d ₂ of the timer relay 29, which has a contact e ₁ . An alarm buzzer 31 is energized and driven via the contact point e ₁ and the reset switch b ₂ .

A glove breakage detecting operation by the attaching / detaching device having the above structure will be described with reference to FIGS. 5 to 7.
In the standby state, the reset switches b ₁ and b ₂ are closed, and the self-holding relays 28 and 30 and the timer relay 2
All the contacts c ₁ , c ₂ , c ₃ , e ₁ , d ₁ , d ₂ of 9 are open. Further, although the inside of the glove insertion portion 12 is sucked by the vacuum pump 14, since the pressure value is close to the atmospheric pressure level unless the glove 1 is set, the low pressure side contact a ₁ of the pressure switch 25 is also opened.

Here, the glove insertion portion 12 in the suction state
When the glove 1 is set as shown in FIG. 2, the pressure in the glove insertion portion 12 decreases as the opening edge portion 13 of the glove 1 is closed by the fitting edge portion 2 of the glove 1. When the pressure switch 25 reaches a predetermined low pressure value, the low pressure side contact a _{1 of} the pressure switch 25 is closed by the operation of the pressure sensor unit 26 (time t ₁ ). Therefore, the self-holding relay 28 is energized and excited, and its contacts c ₁ , c ₂ , c ₃ are closed to shift to the self-holding state, and at the same time, the timer relay 29 is also energized to start counting down. Contacts d ₁ , d
₂ closes. Then, the contact c of the self-holding relay 28
₂ , the solenoid 2 via the contact d ₁ of the timer relay 29
Since 7a is energized, the electromagnetic valve 27 closes, blocking the suction of the vacuum pump 14 inside the glove insertion part 12 and the inflow of air into the glove insertion part 12.

By closing the solenoid valve 27, the glove insertion portion 1
Although the inside of 2 (space S ₁ ) is in a sealed state, the glove insertion part 1
When the glove 1 set to 2 has a damaged portion, the atmosphere flows from the outside through the damaged portion, and the pressure in the space S ₁ rapidly rises toward the atmospheric pressure level. Therefore, in the pressure switch 25, the low-voltage side contact a ₁ eventually opens (time t ₂ ), and when the pressure reaches a predetermined high pressure value, the high-voltage side contact a ₂ closes this time (time t ₃ ). Here, even if the low-voltage side contact a ₁ is turned off, the self-holding relay 28 is in a self-energizing state by its contact c ₁ , so that the contact c _{3 of the} relay 28, the high-voltage side contact a ₂ of the pressure switch 25, and The alarm buzzer 31 is energized via the contact d ₂ of the timer relay 29 to emit an alarm sound.

The timer relay 29 automatically shifts to the demagnetized state when a predetermined count time T has elapsed, and the contacts d ₁ and d _{2 of the} timer relay 29 are opened (time t ₄ ). Therefore, the electromagnetic valve 27 is cut off, and the suction pipe 17 and the air inflow pipe 18
Is released and the pressure in the space S ₁ inside the glove insert portion 12 decreases again, so that the high-voltage side contact a of the pressure switch 25 is released.
₂ It will be opened soon (time t ₅ ).

Therefore, at time t ₄ when the contact d ₂ of the timer relay 29 opens, the alarm buzzer 31 stops its driving as shown by the broken line in FIG.
According to this embodiment, the self-holding relay at time t ₃ 2
At the same time that the alarm buzzer 31 is energized via the contact c _{3 of} 8, the contact a ₂ of the high pressure side of the pressure switch 25 and the contact d ₂ of the timer relay 29, at the same time another self-holding relay 30 is energized to close the contact e ₁ . However, the alarm buzzer 31 is not energized even after the time t ₄ when the contact d ₂ of the timer relay 29 opens and the time t ₅ when the high-voltage side contact a ₂ of the pressure switch 25 opens because the self-energized state is set. It is maintained and continues to emit an alarm sound. Then, by depressing the foot pedal 16 and opening the reset switches b ₁ and b ₂ , the self-holding relays 28 and 30 are reset and the alarm buzzer 3
1 stops its driving. (Time t ₆ ). Alarm buzzer 3
As for the glove 1 in which the presence of the damaged portion is detected by the alarm sound from 1, the power switch 15 is turned off as described above.
Although the vacuum pump 14 can be removed from the glove insertion portion 12 by stopping the vacuum pump 14, the energization of the vacuum pump 14 may be temporarily interrupted by depressing the foot pedal 16.

Further, in the above detection operation, when the glove 1 set in the glove insertion portion 12 has no breakage point, the low-voltage side contact a ₁ of the pressure switch 25 is closed at time t ₁ and each contact of the self-holding relay 28 is closed. When the contacts d ₁ , d _{2 of the} c ₁ , c ₂ , c ₃ and the timer relay 29 are closed and the solenoid valve 27 is closed, the space S ₁ of the glove insert portion 12 is in a low pressure state because there is no air leakage. Is retained. Therefore, pressure switch 2
The high-voltage side contact a ₂ of 5 remains open, and at time t ₄ when a predetermined count time T has passed, the timer relay 29
The alarm buzzer 31 is not driven because the respective contacts d ₁ and d _{2 of} are opened. Further, in this case, since the glove 1 is inflated in the glove insertion portion 12, if the alarm buzzer 31 does not operate and it is recognized that there is no abnormality, the glove 1 is
Put a hand on the valve body and press the push button 22 in the glove insertion portion 12 with the fingertip thereof as described above.
