Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a glove made of a soft resin such as vinyl or an elastomer, and a donning/detaching device for making it easy to put on and take off the glove.

[Conventional technology]

Conventionally, gloves made of vinyl or elastomer (rubber), for example, have been put on and taken off by hand, but the tighter they fit, the more they stick to the hands due to skin moisture, making it very difficult to put on and take off. It was difficult.

Furthermore, when removing gloves from your hands after use, you may touch the surfaces of the gloves with your bare hands that have chemical solutions, etc. Furthermore, if there are small tears in the gloves, if you do not know this and wear them, However, there were problems in that the effects of wearing gloves could not be obtained, which was undesirable from a health and safety standpoint.

[Problem to be solved by the invention]

In view of the above-mentioned problems, the present invention makes it possible to mechanically perform the work of putting on and taking off gloves, which was conventionally done with bare hands, easily and quickly, and without contact with bare hands, and also detects tears in the gloves to improve safety. This was done with the aim of improving the

[Means to solve the problem]

In order to solve the above problems, the present invention provides a glove made of a soft resin such as vinyl or an elastomer, and is characterized in that a reinforcing ring is fixed to the periphery of the fitting opening of the glove. a glove insertion portion formed with an opening edge that can be closely engaged with the peripheral edge; a vacuum pump connected to the glove insertion portion via suction piping; and an air inflow that allows air to flow into the glove insertion portion. Provided is a glove donning and doffing device characterized by comprising: a flow rate control valve that regulates the inflow of air; and a compressed air supply means that supplies compressed air to the glove insertion portion. The aim is to automatically attach and detach the In this glove putting on and taking off device, it is preferable that the glove insertion parts are provided in pairs on the left and right, each connected to an independent vacuum pump, and a pressure switch operated by the internal pressure of the glove insertion parts. a timer relay that closes the circuit for a predetermined count time from the time when the low pressure side contact of the pressure switch closes; and a suction force interrupting electromagnetic device that is energized through the timer relay to close the gap between the glove insertion part and the vacuum pump. By adding a configuration comprising a valve and an alarm unit that is activated when both the high pressure side contact of the pressure switch and the timer relay are closed, it is possible to detect a tear in the glove.

[For production]

To explain the procedure for putting on and taking off the glove according to the first claim, in which the peripheral edge of the fitting opening is reinforced with a reinforcing ring, using the putting on and taking off device according to the second claim, first, when putting on the glove, place the glove in the glove insertion part. At the same time as the glove is inserted, the peripheral edge of the fitting opening of the glove is engaged with the opening edge of the glove insertion part, and the inside of the glove insertion part is suctioned with a vacuum pump to inflate the glove body. Here, the purpose of reinforcing the peripheral edge of the fitting opening of the glove with a reinforcing ring is to prevent the entire glove from being sucked into the glove insertion part during the above-mentioned suction.
This is because the peripheral edge of the fitting opening is brought into close contact with the opening edge by the differential pressure inside and outside the glove generated by the suction. The degree of inflation 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 part from the air inflow pipe by suction using a flow rate control valve. Then, by inserting the hand into the swollen glove and then supplying compressed air from the compressed air supply means into the glove insertion part, the glove comes into close contact with the hand and the wearing of the glove is completed.

Next, when removing the glove from the hand, the gloved hand is put into the glove insertion part, the glove is inflated by suctioning the glove insertion part, and the hand is pulled out, as in the case of putting on the glove.

The putting on and taking off device according to the third aspect has one pair of left and right glove insertion parts, so that gloves can be put on and taken off with both hands at the same time. By connecting independent vacuum pumps to both glove insertion sections, mutual interference of the suction forces of both glove insertion sections can be prevented.

Further, the attachment/detachment device according to the fourth aspect is provided with a glove tear detection mechanism. That is, similarly to the above, the glove is first inflated by suctioning the inside of the glove insertion part with a vacuum pump. When the pressure inside the glove insertion part drops to a predetermined value, the pressure cusp inch senses this and closes its low-pressure side contact, the timer relay closes at the same time, and the solenoid valve shuts off the connection between the glove insertion part and the vacuum pump. At this time, the high pressure side contact of the pressure switch is open, and if a predetermined count time elapses in this state, the timer relay will also open, and from then on, the pressure inside the glove insertion part will eventually rise and the high pressure side Even if the contact closes, the alarm unit will not activate.

However, if there is a tear in the glove, air can flow into the glove insertion part through the tear, causing
When the pressure inside the glove insert rapidly rises (approaching the atmospheric pressure level) and the timer relay opens after a predetermined count time has elapsed, the pressure switch closes its high-pressure side contact, which energizes the alarm section. issue an alarm. In this case,
It is effective to provide a self-energizing means so that the alarm section continues to be driven even after the timer relay opens.

〔Example〕

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

First, in Figure 1, (1) is vinyl or elastic]
A part of the glove made of mer etc. is shown.

(3) is a reinforcing ring made of PTFE or lightweight resin material, which includes an inner ring (3a) with a simple circular cross section in the radial direction, and an inner ring (3a) with a wire diameter larger than the inner ring (3a) and a radial cross section of approximately C. It is composed of a letter-shaped outer ring (3b). This reinforcing ring (3) is fixed to the circumferential edge (2) of the fitting opening of the glove (1) as shown in FIGS. 2 and 3, that is, the inner ring (
3a) into the inside of the fitting opening periphery (2), so that the opening periphery (2) is wrapped around the inner ring (3a), and the outer ring (3b) is fitted on the outside thereof. It can be used for general vinyl gloves, etc., which are widely used. The reinforcing ring (3) is not limited to the illustrated example, and may be integrally embedded or bonded, for example, to the peripheral edge of the fitting opening (2).

Next, FIG. 4 shows the appearance of an embodiment of the glove attachment/detaching device (10), in which (11) is the body, (12)
)(12) is a pair of left and right glove insertion portions opened at the upper front surface of the body (11), and (14)(14) is independently connected to each glove insertion portion (12) by piping. Vacuum pump, (15) (15) is the power switch, (16
) is a foot pedal that opens and closes a foot switch (not shown). Opening edge (13) at the front end of each glove insertion part (12)
As shown in FIG. 5, when the glove (1) described above is inserted into the glove insertion part (12), the
It is adapted to closely engage with the peripheral edge (2) of the fitting opening reinforced by the reinforcing ring (3). Also, as shown in Figure 6,
Each glove insertion part (12) is equipped with a vacuum pump (14).
In addition to the suction pipe (17) extending to the vacuum pump (14), there is also an air inflow pipe (18) that allows air to flow into the glove insertion part (12) during suction by the vacuum pump (14), and a compressed air supply source. Compressed air supply piping (22) extending from (22)
0) is connected, of which the air inflow pipe (18
), there is a flow rate control valve (19) that controls the amount of air flowing into the glove insertion part (12), and a compressed air supply solenoid valve ( 21)
are provided for each.

In the above-mentioned attachment/detachment device, when the power switch (15) is turned on, the vacuum pump (14) (+4) is driven to put the inside of the glove insertion part (12) (12) in a suction state, and the solenoid valve for supplying compressed air is activated. (21) (21) normally closes the compressed air supply piping (20) (20), and when the foot pedal (16) is depressed and the foot switch is turned on, the compressed air supply source (21) (21) is opened. 22
) is supplied to the glove insertion portions (12) (12).

Therefore, for example, when putting on the glove (1) on the hand, first turn on the power switch (15) to drive the vacuum pump (14) (14). ) (12) Gloves (
Set 1). At this time, the space (Sl) between the inner wall of each glove insertion part (12) and the glove (1) is such that the opening edge (2) of the glove (1) is located at the opening edge (2) of the glove insertion part (12).
13), the pressure decreases as the glove (1) comes into close contact with the glove (1), and due to the differential pressure with the internal space (S2) of the glove (1), which is at atmospheric pressure, the glove (1) expands. The outside air flows into the space (Sl) of the glove insertion part (12), which is sucked and has a low pressure, through the air inflow pipe (18), and the amount of restriction of the flow rate control valve (18) is adjusted. Accordingly, the internal pressure of the space (Sl), in other words, the amount of expansion of the glove (1) can be appropriately set. Furthermore, the opening edge (2) of the glove (1) that closely engages with the opening edge (13) of the glove insertion portion (12) is
The gloves (1) are reinforced by the reinforcing ring (3).
) functions as a stopper to prevent the entire glove insertion part (12) from being completely sucked into the glove insertion part (12), and furthermore, the suction acts as a self-sealing effect, sealing the peripheral part of the opening (2) and the opening. The space (S
Completely block air from leaking into l).

Next, the user puts both hands into the glove (101) which is inflated within the glove insertion part (12) (12), and depresses the foot pedal (18). The compressed air supply solenoid valves (21) (21) are energized by the foot switch to open the hitherto blocked pipes (20) (20), thereby allowing the compressed air from the compressed air supply source (22) to open. is the glove insertion part (12)
(12) As the pressure in the space (Sl) increases, the glove (1), which had been inflated, contracts and comes into close contact with the hand.

Then, the compressed air releases the suction state (close engagement state) of the peripheral edge (2) of the glove (1) to the opening edge (13) of the glove insertion portion (12), and the glove (
1) Wearing is completed.

In addition, when removing gloves (1) from hands,
Glove insertion part (12) with both hands in the suction state while wearing the
) (12). Then, each glove insertion part (12
The opening of the glove (1) is closed by engagement with the peripheral edge (2) of the opening of the glove (1), and the opening of the glove (1) is closed as in the case of wearing the glove (1).
) expands. 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.

As mentioned above, according to the tree example, no effort is required;
Moreover, the glove (1) can be put on and taken off without touching the surface of the glove (1) with bare hands. Since there are one pair of glove insertion parts (12) on the left and right sides, it is possible to put on and take off the gloves (1) on both hands at the same time. In addition, the opening periphery (2) of the glove (1) and the opening 1'' edge (13) of the glove insertion portion (12)
V: If the contact is incomplete, the glove insertion part (
12), the glove (1) will not be able to fully inflate, but the left and right glove insertion sections (12) (12) are equipped with independent vacuum pumps (14) (14).
Since the structure is such that there is no mutual interference of suction forces, even if air leaks as described above at one glove insertion part (12), for example, the suction force at the other side will not be affected at all. do not. It goes without saying that the leakage of the atmosphere can easily be eliminated by slightly moving the peripheral edge (2) of the fitting opening to correct the state of engagement with the opening edge (13).

Next, FIG. 7 schematically shows a part of the piping as another embodiment of the glove donning/detaching device according to the present invention. This embodiment is designed to prevent the glove (1) from being worn on the hand without realizing it in the event that a part of the glove (1) is damaged. A tear detection mechanism is added to the device, and the electrical circuit diagram of the detection mechanism is shown in FIG.

That is, (23) extends from the glove insertion part (12) to the vacuum pump (14), is provided in the suction pipe (17), and is a pressure sensor part (24) that operates by sensing the pressure inside the glove insertion part (12). ), a low-pressure side contact (al) that works in conjunction with the pressure sensor part (24) and becomes conductive when the pressure inside the glove insertion part (12) decreases to a predetermined low pressure value, and a This pressure switch has a high pressure side contact (a2) that becomes conductive when the pressure rises and reaches a predetermined high pressure value. In addition, (25) is a connection between the pressure sensor (24) in the suction pipe (17) and the vacuum pump (1).
4) and the air inflow pipe (18) at the same time.

In Fig. 8, (bl) (b2) is the foot pedal (1
6) The reset switch (26), which opens when the user depresses the switch (see Fig. 4), is energized via the high voltage side contact (al) and the reset switch (bl), and the contact (cl)
It is a self-holding relay having (C2) and (C3). (2
7) is a timer relay that is energized at the same timing as the energization of the self-holding relay (26), and has a time limit contact (di) (C2) that closes only for a predetermined count time. The solenoid of the solenoid valve (25) is energized via the contact (C2) of the relay (26) and the time limit contact (dl) of the timer relay (27). (28) is the contact (C3) of the relay (26) and the high pressure side contact (C3) of the pressure switch (23).
2) A self-holding relay that is energized via the time limit contact (C2) of the timer relay (27) and has a contact (el). (28) is an alarm buzzer, and the contact (el) is the reset switch.

It is driven by being energized through the gate (C2).

The glove tear detection operation by the donning/detaching device having the above configuration will be explained with reference to FIGS. 7 to 9. In the standby state, the reset switch (bl) (C2) is closed and the self-holding relay (26 ) (28) and each contact (cl) (C2) (C3) (el
)(di)(C12) are also all open. In addition, although the inside of the glove insertion part (12) is suctioned by the vacuum pump (14), if the gloves (1) are not set, the pressure is relatively close to the atmospheric pressure level, so the low pressure of the pressure switch (23) The side contact (al) is also open.

Here, insert the glove (1) into the glove insertion part (12) which is in the suction state
) as shown in Figure 5, the glove insertion part (
12) The pressure decreases as the opening of the glove (1) is blocked by the fitting opening periphery (2) of the glove (1). When the pressure reaches a predetermined low pressure value, the pressure switch (23) activates the pressure sensor. The low voltage side contact (al) is closed by the operation of the section (24) (time t1), and therefore the self-holding relay (24) is closed (time t1).
B) is energized and excited, and each of its contacts (cl) (C2
) (C3) closes and transitions to a self-holding state, at the same time, the timer relay (27) is also energized and starts counting down, and its respective contacts (dl) (C2) are closed. Then, the solenoid valve (25) is energized through the contact (C2) of the self-holding relay (26) and the contact (dl) of the timer relay (27), and the valve is closed, and the glove insertion part is removed by the vacuum pump (14). (12) and the glove insertion part (12).
) to block air from entering the area.

By closing the solenoid valve (25), the inside of the glove insertion part (12) becomes airtight, but if there is a damaged part in the glove (1) set in the glove insertion part (12), the damaged part Atmospheric air flows in from the outside through the glove insertion part (12), and the pressure inside the glove insertion part (12) rapidly rises to the atmospheric pressure level. Therefore, the pressure switch (23) has its low pressure side contact (al)
eventually opens (time t2), and when the pressure reaches a predetermined high pressure value, the high pressure side contact (C2) closes (time t3). Here, even if the low voltage side contact (al) is OFF, the self-holding relay (2G) is in a self-energized state by its contact (cl), so the contact of the relay (2B) (
C3), the alarm buzzer (29) is energized via the high pressure side contact (C2) of the pressure switch (23) and the contact (C2) of the timer relay (27), and emits an alarm sound.

The timer relay (27) automatically shifts to the demagnetized state when a predetermined count time (T) has elapsed, and each of its contacts (dD(C2) opens (time t4). Therefore, the solenoid valve (25) The power is cut off, the suction pipe (17) and the air inflow pipe (18) are opened, and the pressure inside the glove insertion part (12) decreases again, so the high pressure side contact ( C2) will also open soon (time t5).
). Therefore, at time t4 when the contact point (C2) of the timer relay (27) opens, the alarm buzzer (2S) stops driving as shown by the broken line in FIG. According to
At the same time that the alarm buzzer (29) is energized via d2), another self-holding relay (28) is energized and closes its contacts (41), shifting to a self-energized state.
Time t4 when the contact (d2) of the timer relay (27) opens;
Even after the time t5 when the high pressure side contact (a2) of the pressure switch (23) opens, the alarm buzzer (29) remains energized and continues to emit the alarm sound. Then, by depressing the foot pedal and opening the reset switch (bl) (b2), the self-holding relays (26) and (28) are set, and the alarm buzzer (28) stops driving (time te). Incidentally, when the foot pedal is depressed, a foot switch (not shown) is simultaneously turned on, and compressed air from the compressed air supply source (22) described in the previous embodiment shown in FIGS. 4 to 6 is supplied to the glove insertion part. (12) and take out the gloves (1).

In addition, in the above detection operation, if there is no damaged part in the glove (1) set in the glove insertion part (12), at time t1
The low pressure side contact (al) of the pressure cass inch (23) closes,
Each contact (cl) (c2) (c) of the self-holding relay (26)
3) and each contact (di) (d) of the timer relay (27)
2) is closed and the solenoid valve (25) is closed, a low pressure state is maintained within the glove insertion portion (12) because no air leaks inside. Therefore, the high pressure side contact (a2) of the pressure switch (23)
) remains open until a predetermined count time (T
) at time t4, each contact of the timer relay (27) opens, so the alarm buzzer (28) is not activated. Also, in this case, since the glove (1) is in a swollen state inside the glove insertion part (12), the above detection result causes the alarm buzzer (2) to be activated.
If 8) does not operate and there is no abnormality, remove the gloves (1).
If the glove (1) is put on with the user's hand and the foot pedal is pressed to blow out compressed air into the glove insertion part (12) as described above, the glove (1) can be put on immediately.

As described above, according to this embodiment, in addition to the effects of the embodiments shown in FIGS. 4 to 6 described above, it is possible to detect whether or not the glove (1) is torn before it is put on. This prevents the wearer from wearing the item without knowing that there is a tear.

Note that the tear detection mechanism is not limited to the example shown; for example, the relay may be a non-contact type, or an alarm lamp may be used in addition to an alarm buzzer as an alarm unit, or an indicator may be used when gloves can be used. Providing means is optional. In addition, in this embodiment, the solenoid valve for cutting off the attraction force (
25), both the suction pipe V (17) and the air inflow pipe (18) are configured to open and close, but it is also possible to open and close only the suction pipe (17), and in this case, the timer Flow rate control valve (19) installed in the atmosphere inflow pipe (18)
Set according to the aperture amount.

〔Effect of the invention〕

As described above, according to the present invention, the following effects can be achieved.

(i) Gloves made of vinyl or elastomer can be put on and taken off easily and quickly, making it possible, for example, in factories to create lines that connect work that requires the use of gloves with work that does not require the use of gloves. Become.

Since it is easy to put on and take off thin gloves or long gloves that are in close contact with the skin of the hands, it is useful in the precision machinery industry, electronic engineering, food industry, medical care, etc. where handling with bare hands is disliked.

Since the 610 glove can be put on and taken off without touching the surface of the glove with bare hands, it is extremely effective in terms of safety and health when handling substances that are harmful to the human body and the skin of hands, such as drugs and poisonous substances.

011) With the glove tear detection mechanism, it is possible to discover tears in the gloves before putting them on, and there is no need to put on the gloves without knowing that they are torn, so that the effects of using the gloves can be reliably obtained.
