Description

System for Connection/Separation between Chemical Supply Hose and Plant-side Coupler Unit}

The present invention relates to a facility for supplying chemicals in a semiconductor factory or a chemical factory, and more particularly, a chemical supplied from a chemical supply source such as a tank lorry, through a hose, to the interior of a building of a semiconductor factory or a chemical factory. It relates to a connection/disconnection system between a hose and a building-side coupler unit for supply.

Semiconductor factories and chemical factories use various types of chemicals in large quantities. Here, the chemical includes liquid substances such as hydrofluoric acid, sulfuric acid, hydrochloric acid, ammonia, hydrogen peroxide, plating solution, photoresist, developer, etc., or paste substances such as slurry used for chemical mechanical polishing (CMP).

These chemicals are often toxic or flammable, which are harmful to the human body or the environment, and are stored in containers such as tanks or drums, transported by tank lorries or trucks, and supplied to factories. On the other hand, there are many cases where high cleanliness is required inside such factories.

Therefore, when supplying the transported chemicals to a semiconductor plant or a chemical plant, a coupler unit is provided that is isolated from the production facility and connected to a chemical storage tank in the plant, and a chemical supply hose is connected to the coupler unit to transfer the chemical to the chemical storage tank. B It is common to supply it to production facilities. That is, the coupler unit is a chemical relay means between a chemical supply hose (hereinafter, simply referred to as “hose”) and a chemical storage tank.

The coupler unit, also called ACQC unit (Automatic Clean Quick Coupler Unit), is installed separately from the factory building in the form of a cabinet or booth, or installed on the outer wall of the factory building. In the coupler unit, one end of a female connector to be connected to a hose is exposed on the exterior of a cabinet-shaped housing or on the exterior wall of a building, and the other end of the female connector is connected to a chemical storage tank or production facility inside the housing or building by piping. Is composed.

On the other hand, the hose is equipped with a male connector that matches the female connector at its end, and the end of each of the male and female connectors does not leak chemicals when the male and female connectors (i.e., hose and coupler unit) are separated from each other. , The cap is covered to prevent air or foreign substances from penetrating.

The coupling between the coupler unit and the hose configured as described above is performed by an operator (typically a tank lorry driver) aligning the male and female connectors, removing the cap of the male and female connectors, and engaging the male and female connectors.

However, as described above, since these chemicals are harmful to the human body or the environment, careful attention should be paid to prevent accidents such as leakage of chemicals or exposure of workers to chemicals when connecting/separating hoses and coupler units. Must wear fireproof clothing. However, it is very cumbersome for the worker (tank lorry driver) to put on and take off the fireproof clothing, but the worker inside the factory (clean room) wearing the fireproof clothing comes out of the factory to connect/disconnect the hose and the coupler unit. Not only is this more cumbersome, but it may be practically impossible, especially depending on the weather conditions.

In this way, since the connection/separation of the hose and the coupler unit is a very cumbersome and dangerous operation, automation has recently been promoted (see, for example, Patent Document 1). In the automatic fastening system between the chemical tank lorry and the ACQC unit disclosed in Patent Document 1, a separate clean booth and frame are provided adjacent to the female connector of the ACQC unit in the form of a cabinet, and a hose can be mounted in the clean booth (to the frame). A hose holder (moving unit) capable of moving forward and backward toward the ACQC unit (female connector), a cap removing means capable of automatically removing the caps of each male and female connector, and a transfer unit that drives the hose holder forward and backward toward the female connector. do.

According to the fastening system of Patent Document 1, an operator (tank driver) simply mounts and fixes the hose with the cap fastened to the hose holder, removing the cap of the male and female connector, moving the hose holder toward the female connector, and Since the hose (male connector) is automatically fastened to the connector, it is possible to safely connect the hose to the ACQC unit, and the operator does not need to wear fireproof clothing.

However, as shown in Fig. 4, the hose 20a has a considerable weight since it includes the metal flanges 22a and 25a and the male connector 21a. In addition, the female connector of the coupler unit is exposed deep inside the space formed by being recessed or penetrated from the outer wall of the building or the outer surface of the housing, which prevents the female connector of the coupler unit from being exposed to the environment outside the building as it is. This is to secure a space for arrangement and movement of hose holders that stably mount and fix the hose during chemical supply after connecting and connecting the male and female connectors.

Therefore, it is inconvenient and not easy for a worker to lift a heavy hose and push it to the inside of the space to accurately mount and fix it on the hose holder, and there is a possibility of misalignment, and it may be a burden on the body of the worker such as the waist.

1 to 3, respectively, a plan view and a side view schematically showing an arrangement configuration of a connection/separation system (hereinafter, also simply referred to as a'system') between a chemical supply hose and a coupler unit according to a preferred embodiment of the present invention. And a perspective view, and FIG. 4 is a perspective view showing a hose connected to the coupler unit by the system. With reference to FIGS. 1 to 4, the arrangement configuration of the system according to the present embodiment will be described first.

1 to 3, the system includes a coupler unit 10, hoses 20a, 20b, and hose mounting/transporting devices 100, 200a, 200b.

On the other hand, the system includes two hoses (20a, 20b), and accordingly, the coupler unit 10 also has two coupler-side connectors (13a, 13b) connected/separated to the two hoses (20a, 20b) respectively. Equipped with, hose mounting / transfer device (100, 200a, 200b) to connect / separate the two hoses (20a, 20b) to the respective coupler-side connectors (13a, 13b), two hose clamping units (200a) , 200b). Here, the first hose 20a and the first coupler-side connector 13a are configured to supply chemicals from a chemical supply source outside the building (factory) such as a tank lorry to a chemical storage tank (not shown) or production facilities inside the building. In addition, the second hose 20b and the second coupler-side connector 13b contain an inert gas such as nitrogen so that the supply of chemicals through the first hose 20a and the first coupler-side connector 13a is smoothly performed. It is a configuration for supplying from the inside of the building (factory) to the chemical supply source outside the building. That is, the inert gas is blown into the chemical supply source through the second hose 20b, which is an inert gas hose, so that the chemicals smoothly come out to the first hose 20a, which is a chemical supply hose.

These two hoses (20a, 20b), two coupler-side connectors (13a, 13b), and two hose clamping units (200a, 200b) have the same basic configuration between the paired elements, so the following is mainly the first The elements of (elements denoted by'a' in reference numerals) are described, and detailed descriptions of the second elements (elements denoted by'b' in reference numerals) are omitted, excluding differences from the first element. . In addition, hereinafter, when it is not necessary to distinguish between the first element and the second element, or when referring together,'a' and'b' are omitted from the reference numerals and only numbers are indicated.

As described above, in this embodiment, the system is described as having two hoses 20a and 20b, two coupler-side connectors 13a and 13b, and two hose clamping units 200a and 200b, but the second hose 20b ) And the second coupler-side connector 13b and the second hose clamping unit 200b for connecting/separating them may be omitted.

The coupler unit 10 is disposed inside the building at a predetermined distance L away from the building outer wall 1, opposite to the opening 2 formed through the outer wall 1 in a part of the building. In this embodiment, the coupler unit 10 is implemented in the form of a booth 11 having an inner space blocked from the outside. The coupler unit 10 is provided with a coupler-side connector 13 to which the hose 20 is connected.

One end of the coupler-side connector 13 passes through the housing 12 recessed in the Y-axis direction and is exposed to the external space S2 of the booth 11 to face the hose 20, and the other end is inside the booth 11 It is connected to a chemical storage tank (not shown) or a production facility (not shown) through pipes and valves. One end of the coupler-side connector 13 exposed to the outside of the booth 11 is covered with a cap (stopper) 14 for preventing leakage of chemicals and inflow of foreign substances. In addition, as shown in FIG. 3, around one end of the exposed coupler-side connector 13, when the hose-side connector 21, which will be described later, is connected to the coupler-side connector 13, the connection is unintentionally released by holding them. There is provided a lever 15 to prevent it.

The hose 20 is equipped with a hose-side connector 21 that is connected/separated from the coupler-side connector 13 as shown in FIG. 4. Specifically, a hose-side flange 22 is connected to the end of the hose portion of the hose 20, and the hose-side connector 21 includes a connector-side flange 25 corresponding to the hose-side flange 22. The hose-side connector 21 is mounted on the hose 20 by fastening means such as bolts 27/nuts 28 through two flanges 22 and 25 and a gasket (not shown) interposed therebetween. do.

In the hose-side connector 21a, in order to prevent erroneous connection between the hose 20a and the coupler unit 10, a unique key code 23 according to the type of chemical supplied by the hose 20a. ) Is formed. The key code 23 may be formed of a predetermined groove or protrusion pattern formed on the outer circumferential surface of the hose-side connector 21a. In addition, a confirmation key code (not shown) corresponding to the key code 23 of the hose-side connector 21a may be formed on the inner circumferential surface of the coupler-side connector 13a. In addition, the key code 23 and the key code for confirmation may be formed at a plurality of locations at a predetermined angle along the circumferential direction from the outer peripheral surface of the hose-side connector 21a and the inner peripheral surface of the coupler-side connector 13a, respectively. Therefore, the hose-side connector (21a) and the coupler-side connector (13a) not only have to match (match) the key code 23 formed on each of the key code for confirmation, but also have to be aligned to the corresponding positions to mutually fasten. It is possible. A detailed alignment method of the key code 23 and a jig for the same will be described later.

On the other hand, in FIGS. 1 to 4, the front end of the hose-side connector 21 is shown to be open, but the distal end of the hose-side connector 21 is similar to the distal end of the coupler-side connector 13 to prevent leakage of chemicals and inflow of foreign substances The cap (not shown) is detachably covered. In addition, although only the first hose 20a supplying the actual chemical is illustrated and described in FIG. 4, the second hose 20b, which is an inert gas hose, also has the same basic structure as the first hose 20a. However, the second hose 20b is different in size from the first hose 20a, and may have a different key code or may not have a key code as in this embodiment.

Referring again to FIGS. 1 to 3, the hose mounting/transporting device 100, 200 includes an opening 2 formed in the outer wall 1 of a building, and the space between the opening 2 and the coupler unit 10 It is disposed in (S1) and is configured to be able to advance and retreat in the Y-axis direction toward the coupler unit 10 by mounting and fixing the hose 20. In particular, the coupler unit 10 and the hose mounting/transfer device 100, 200 are connected to the hose-side connector 21 and the coupler-side connector 13 when the hose 20 advances toward the coupler unit 10. It is positioned and arranged as possible.

As described above, in this embodiment, the coupler unit 10 is disposed inside the building by being spaced apart from the building outer wall 1 to face the opening 2 formed through a part of the building outer wall 1, and a hose mounting/transporting device ( 100 and 200 are disposed in the opening 2 and the space S1 between the opening and the coupler unit 10. Therefore, when the first worker (tank lorry driver) from the outside of the building mounts and fixes the hose 20 to the hose mounting/transporting devices 100 and 200 through the opening 2, the space S1 inside the building A second worker (worker inside the factory) can remove the caps 14 (not shown) of the coupler-side connector 13 and the hose-side connector 21, and connect the hose-side connector 21 to the coupler-side connector 13. have.

At this time, since the first worker is not exposed to chemicals (because each connector 13, 21 is capped), there is no need to wear a cumbersome fireproof suit. On the other hand, since the second worker may be exposed to chemicals (because the caps of each connector are attached and detached), they must wear fireproof clothing. However, since the second worker does not go out of the building wearing fireproof clothing, it is much less hassle compared to the prior art. In particular, if the second worker is already working inside the building wearing fireproof clothing, it is possible to connect/disconnect the hose 20 to the coupling unit 10 simply by moving inside the building.

At this time, if the internal space (S3) in which the second worker is usually working is a space requiring high cleanliness, such as a clean room, this internal space (S3) and a space in which the hose mounting/transporting devices 100 and 200 are disposed ( S1) is preferably isolated. To this end, the two spaces S1 and S2 are isolated by the inner wall 3 of the building and the door 4 as shown in FIG. 1, and more preferably, the interior space S3 is maintained at a positive pressure to the door ( When 4) is opened, it is possible to prevent air from flowing into the inner space S3 from the space S1 where the hose mounting/transfer devices 100 and 200 are disposed. Furthermore, an air curtain or air shower is installed in addition to the door 4 between these two spaces (S1, S3), so that a second worker wearing a fireproof suit removes foreign substances such as dust adhering from the space (S1) and It can be made to enter the space (S3). In addition, by installing a door 30 in the opening 2, when the system is not in use, the door 30 can be closed to prevent the outside air from flowing into the space S1.

Meanwhile, each component of the system of the present embodiment is arranged in consideration of ergonomics. The hose 20, in particular the first hose 20a, has a considerable weight as it comprises flanges 22, 25 and connectors 21 made of metal. Accordingly, each component of the system of the present embodiment is arranged so that the first or second operator handling such a heavy object can work without bending his back or raising his arm. Specifically, as shown in Figs. 1 and 2, the height H1 from the ground at which the hose mounting/transporting devices 100 and 200 are installed to the lower end of the opening 2 is about 800 to 1000 mm, The height H2 of the opening 2 may be about 400 to 600 mm, and the width W of the opening 2 may be about 600 to 1000 mm. In addition, the length (L) in the Y-axis direction of the space (S1) may be about 600 ~ 1000mm so that the second worker can work by approaching the hose mounting/transfer device (100, 200). Meanwhile, the thickness t of the outer wall 1 is determined according to the design specifications of the building, but may be about 250 to 600 mm. In addition, the Y-axis length L of the space S1 may be adjusted according to the thickness t of the outer wall 1 and the Y-axis length of the hose mounting/transporting devices 100 and 200.

On the other hand, elements shown by reference numerals 40 and 41 in FIGS. 2 and 3 are a support 40 that supports hose mounting/transfer devices 100 and 200 stably installed on the lower surface of the opening 2 to maintain the horizontal And height adjuster (41). In this case, when the hose mounting/transfer device 100, 200 in FIG. 2 is spanned on the bottom surface of the recessed space S2 of the coupler unit 10 and the bottom surface of the opening 2, the pedestal 40 is omitted. In addition, the height of the lower surface of the space (S2) and the lower surface of the opening (2) coincide, and the hose mounting/transfer device (100, 200) is connected to the lower surface of the space (S2) and the lower surface of the opening (2). In the case of running on, both the pedestal 40 and the height adjustment device 41 may be omitted.

Next, the hose mounting/transporting devices 100 and 200 will be described in detail with reference to FIGS. 5 to 14.

Accordingly, by engaging the latch 113 and the latch 122, the lower sliding table 120 is driven to slide in the Y-axis direction following the movement of the movable part 112 in the Y-axis direction.

At this time, the moving range of the stopper 113 is regulated by the stoppers 114 and 115, and accordingly, the sliding (advancing and retreating) range of the lower sliding table 120 is also regulated. The stoppers 114 and 115 may be implemented as, for example, a limit switch to stop the driving of the movable part 112 when the stopper 113 contacts. 6 shows a state in which the latch 113 has moved to the front stopper 114, and shows that the front end of the lower sliding table 120 is advanced to a position slightly exceeding the front end of the base table 101. Able to know.

8 shows a state in which the stopper 113 has moved to the rear stopper 115 on the contrary, and the rear end of the lower sliding table 120 exceeds the rear end of the base table 101 and leaves the opening 2 It can be seen that it has retreated to the outside of the exterior wall (1) of the building. In addition, the upper sliding table 130 is more retracted than the lower sliding table 120, and thus the hose clamping unit 200 thereon is also exposed outside the opening 2, and further, the hose guide 106 is also opened ( 2) It is withdrawn (retreated). The hose guide 106 can be withdrawn by pulling the hose guide 106 toward himself without a separate driving means in this embodiment. On the other hand, the advance and retreat mechanism of the upper sliding table 130 and the hose clamping unit 200 will be described later. However, as in FIG. 8, the upper sliding table 130 and the hose clamping unit 200 can be retracted more than the lower sliding table 120, although not shown in FIG. 6, the upper sliding table 130 and the hose clamping unit 200 are clamped. The unit 200 may advance further toward the coupler unit 10 than the lower sliding table 120,

In this way, when the lower sliding table 120, the upper sliding table 130, the hose clamping unit 200, and the hose guide 106 are pulled out (retracted) from the opening 2, the first operator can remove the hose 20. It becomes easier to mount and fix on the hose mounting/transfer device 100, 200. In addition, if the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are further advanced than the front end of the base table 101, the second operator connects the hose 20 to the coupler unit 10 ), it becomes easier to connect/disconnect.

Referring to FIG. 6 again, a guide rail 124 is fixedly disposed on the upper surface of the lower sliding table 120, and the upper sliding table 130 is slidably installed on the guide rail 124 along the Y-axis direction. do. Similarly, a guide rail 134 is fixedly disposed on the upper surface of the upper sliding table 130, and a clamp base plate 201 to which the hose clamping unit 200 is fixed on the guide rail 134 is located along the Y-axis direction. It is installed to be slidable. Therefore, the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are each independently or interlocked with each other to advance and retreat in the Y-axis direction, and the upper sliding table 130 and the hose clamping unit 200 ), it is possible to advance and retreat beyond the end of the lower sliding table 120.

On the other hand, in this embodiment, the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are independently or interlocked with each other to advance and retreat in the Y-axis direction, but a certain section (for example, two stoppers 114 , 115), it may be preferable that the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 move together. To this end, a configuration similar to the latches 113 of the sliding drive unit 110 and the latches 122 of the lower sliding table 120 described above are used as the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200. ) Can be applied between.

Specifically, in this embodiment, as shown in FIG. 6, a pair of latches 125 are provided on one side of the lower sliding table 120, and one side of the clamp base plate 201 having a height corresponding thereto To provide a clasp 205 is inserted between the pair of clasps 125 to be caught. Therefore, the lower sliding table 120 and the hose clamping unit 200 can move together at the same time. However, in order to move the hose clamping unit 200 independently of the lower sliding table 120, a means for releasing the engaging state of the pair of latches 125 and the latches 205 is required. To this end, in this embodiment, the pair of latches 125 are configured to be liftable by the lifting means 126, and when the pair of latches 125 rises, the sliding table 120 engages with the latches 205 And the hose clamping unit 200 moves together, and when the pair of latches 125 descends, it does not engage with the latches 205 so that the lower sliding table 120 and the hose clamping unit 200 can move independently. Here, the lifting means 126 may be implemented as, for example, a hydraulic cylinder, a solenoid plunger, a toggle latch, or the like.

On the other hand, when raising the pair of latches 125 by the lifting means 126, as a result of independent movement of the lower sliding table 120 and the hose clamping unit 200, the latches 205 become a pair of latches ( 125), it is impossible to move the lower sliding table 120 and the hose clamping unit 200 together because the rising clasp 125 and the clasp 205 collide or do not engage with each other. . To prevent this, in this embodiment, a clasp detection sensor 127 is provided between the pair of clasps 125, so that even if the operator operates the lifting means 126, the clasp detection sensor 127 is placed on the clasp 205 If it does not detect that) is located, it warns the operator through a warning sound and the like and stops the lifting means 126 from operating. The latch detection sensor 127 may be implemented as an optical sensor or a contact sensor.

In addition, the lower sliding table 120, the upper sliding table 130, and the clamp base plate 201 may be connected to each other by a wire 151. Specifically, wire fixtures 153 and 155 are provided on the upper surface of the lower sliding table 120 and the lower surface of the clamp base plate 201 to which the wires 151 are fixed, as shown in FIG. 7 (a). And, by installing a pair of rollers 152 in the wire holes 135 formed at both ends in the Y-axis direction of the upper sliding table 130, a pair of rollers 152 and two wire fixtures (153, 155) To form a connecting wire loop.

Therefore, in the state shown in (a) of FIG. 7, if the pair of latches 125 and the latches 205 are engaged, even if the lower sliding table 120 is driven forward and backward by the sliding driving unit 110, the lower sliding table In addition to 120, the upper sliding table 130 and the clamp base plate 201 are advancing and retreating at the same time, and the hose clamping unit 200 (clamping) in a state where the pair of latches 125 and the latches 205 are not engaged. When the base plate 201 is moved independently from the lower sliding table 120, as shown in (b) and (c) of FIG. 7, the upper sliding is performed by half the distance the clamp base plate 201 has moved. The table 130 moves following the clamp base plate 201. In this way, the upper sliding table 130 and the clamp base plate 201 can be smoothly slid, and the range in which the hose clamping unit 200 can move forward and backward can be stably expanded.

In addition, as shown in Figure 7 (a), by biasing the wire fixtures 153, 155 from the center of the length direction (Y-axis direction) of the lower sliding table 120 to one side, the upper sliding table 130 And, it is possible to make the advanceable range (a) and the retractable range (b) of the clamp base plate 201 different.

Meanwhile, in FIGS. 6 and 7 and the above description, the wire 151 may be replaced with a belt or a chain, and further, a gear transmission mechanism. In addition, in the above, the lower sliding table 120 and the clamp base plate 201 are engaged or disengaged by the latch 125 and the latch 205, so that the lower sliding table 120 and the upper sliding table 130 and the hose Although the clamping unit 200 is implemented to move simultaneously or in conjunction with each other, this can be changed. That is, for example, a mechanism capable of engaging/disengaging between the lower sliding table 120 and the upper sliding table 130 is provided, or the lower sliding table 120 is simultaneously with both the upper sliding table 130 and the clamp base plate 201. Alternatively, an optional engagement/disengagement mechanism may be provided. Further, in the above, the lower sliding table 120, the upper sliding table 130, and the clamp base plate 201 are made to move in conjunction with each other using an interlocking mechanism such as a wire loop, but the interlocking mechanism may be omitted.

Meanwhile, the corrugated covers 136 and 137 omitted in FIG. 6 cover the upper sliding table 130 at the front and rear of the clamp base plate 201, and the upper sliding table 130 and the lower sliding table below it from chemicals, etc. 120) Protect your back. At this time, as the clamp base plate 201 moves on the upper sliding table 130, the area of the upper surface of the upper sliding table 130 exposed before and after the clamp base plate 201 changes. In order to cope with the change, the pleat covers 136 and 137 have a structure that can be stretched in the Y-axis direction.

On the other hand, in this embodiment, the sliding table is composed of two stages of the lower sliding table 120 and the upper sliding table 130, but depending on the application, one of the upper or lower sliding tables may be omitted to form a single stage. . In addition, on the contrary, depending on the application, the sliding table may be configured in three or more stages.

In addition, the sliding driving unit 110 automatically slides the lower sliding table 120 using power, but the operator may manually move even the sliding driving unit 110.

Next, the hose clamping unit 200 will be described in detail with reference to FIGS. 9 to 14.

First, FIGS. 9 and 10 are perspective views illustrating a hose clamping unit, FIG. 11 is an exploded perspective view, and FIGS. 12 and 13 are perspective views illustrating an open state of the hose clamping unit. Meanwhile, only the first hose clamping unit 200a for the first hose 20a is shown in FIGS. 9 to 13, and only the first hose clamping unit 200a is described below, but the second hose clamping unit 200b ) Also has the same basic structure as the first hose clamping unit 200a. However, components corresponding to the auxiliary clamp 260 of the first hose clamping unit 200a, the key code alignment jig 243, and the alignment check sensor 249 are omitted from the second hose clamping unit 200b.

9 to 13, in particular, referring to FIG. 11, the hose clamping unit 200 is large, a clamp base plate 201 slidably mounted on the above-described upper sliding table 130 in the Y-axis direction, and a clamp base A fixed support part 210 fixed on the plate 201, a flow support part 220 coupled to the fixed support part 210 to allow some flow, and a main clamp 230 coupled to the flow support part 220 and auxiliary A clamp 260 is provided.

The fixing support 210 is made of a pair of fixing plates 211 and 212 which are opposed to each other and are erected and fixed to the clamp base plate 201. A pair of substantially rectangular fixing plates 211 and 212 each have a large semicircular opening 216 with an open top, and the large opening 216 has a plurality of small semicircular openings 213 again. Is formed. In addition, a plurality of recessed grooves 215 are formed on inner surfaces of each of the pair of fixing plates 211 and 212 facing each other. In addition, a fixing pin hole 217 is formed on an outer surface of the fixing plate 211 on the side of the main clamp 230 among the pair of fixing plates 211 and 212. The use and function of the large opening 216, the small opening 213, the groove 215, and the fixing pin hole 217 will be described later.

The flow support 220 includes a support block 221 in an approximately arch shape, a hose receiving portion 224 having a substantially semi-cylindrical shape for accommodating the hose 20 on the inner surface, and both ends in the Y-axis direction of the hose receiving portion 224 It includes a pair of side plates 222 in the shape of an approximately arch that is fixed to. Here, the length of the hose accommodating portion 224 in the Y-axis direction is slightly larger than the length in the Y-axis direction of the support block 221, so that the end of the support block 221 in the Y-axis direction and the inner surface of the pair of side plates 222 The space is slightly separated. The Y-axis direction end of the support block 221 separated in this way and the inner surface of the pair of side plates 222 are connected by a connecting rod 223 made of an elastic material such as rubber, and the outer peripheral surface of the hose receiving part 224 is supported. The hose receiving portion 224 is mounted on the support block 221 in a state in contact with the inner circumferential surface of the block 221. Therefore, the hose accommodating portion 224 and both side plates 222 are fixed to the support block 221 to allow some flow. Meanwhile, a plurality of recessed grooves 225 are formed on the outer surface of the support block 221 in the Y-axis direction.

In this way, the hose receiving part 224 and the both side plates 222 are fixed to the support block 221 so as to be flowable to some extent, and the flow support part 220 is inserted into the large opening 216 of the fixed support part 210. Then, as shown in FIG. 9, a pair of fixing plates 211 and 212 of the fixing support 210 are inserted between the support block 221 and the pair of side plates 222, and the fixing support 210 The connecting rod 223 of the flow support part 220 is inserted into the small opening 213, so that the fixed support part 210 and the flow support part 220 are coupled. At this time, the groove 215 of the fixed support part 210 and the groove 225 of the flow support part 220 shown in FIG. 11 face each other, and an elastic body such as a spring in the space formed by both grooves 215 and 225 (Not shown) is interposed. Accordingly, the flow support 220 is fixed to the fixed support 210 so as to be able to flow to some extent by the elastic body (not shown) interposed in the grooves 215 and 225 and the connecting rod 223 made of an elastic material.

In addition, on the outer surfaces of both side plates 222 of the flow support part 220, the lower clamps 231 and 261 of the main clamp 230 and the auxiliary clamp 260, respectively, are provided by respective connecting members 237 and 267. It is fixed. Accordingly, the main clamp 230 and the auxiliary clamp 260 are relatively movable to a certain degree with respect to the fixed support 210 and the clamp base plate 201 together with the flow support 220 which is movable to some extent.

The reason why the main clamp 230 and the auxiliary clamp 260 are configured to be flowable is as follows. First, since the hose 20 is a considerable weight as described above, the hose guide 106 supports the rear hose portion of the hose side connector 21, but the hose is not supported by the hose clamping unit 200. The rear hose portion of the side connector 21 can be drooped down. In addition, the hose 20 from the tank lorry to the coupler unit 10 may not be in a straight line and may be bent and disposed. In addition, while the hose 20 is connected to the coupler unit 10 and the chemical is supplied, the supply pressure of the chemical is not constant and fluctuations may occur. Even if the hose 20 is clamped by the hose clamping unit 200 due to these various factors, the hose-side connector 21 may be eccentric or inclined with respect to the coupler-side connector 13. Of course, the clamps 230 and 260 and the connectors 13 and 21 are provided with packings to buffer fluctuations, eccentricities, and inclinations and maintain a sealed state, but packing deteriorates due to long-term repeated impact, eccentricity, and inclination. An accident may occur in which a chemical leak or the connectors 13 and 21 are disconnected.

On the other hand, according to the present embodiment, since the clamps 230 and 260 are supported in a state capable of being moved to some extent by the flow support 220, the hose-side connector 21 clamped to the clamp 230 is oscillated, eccentric, By dynamically adapting to the inclination, etc. in real time, the impact or asymmetrical pressure that may accumulate in the packing can be significantly reduced.

On the other hand, the configuration in which the clamp (consequently the hose-side connector 21) is supported so that it can flow has the effect of preventing an accident in which a chemical leak or the connectors 13 and 21 are disconnected as described above, but the connector When the (13, 21) is connected/disconnected (especially when connected), the alignment between the connectors (13, 21) is misaligned due to the inclination or eccentricity of the hose-side connector (21), which may cause inconvenience to work. Therefore, when connecting/disconnecting the connectors 13 and 21, it is necessary to lock the clamp (as a result, the hose-side connector 21) so that it does not flow.

To this end, in this embodiment, the hose clamping unit 200 is provided with a flow lock 250. Specifically, the flow locking part 250 is fixed to the lower clamp 231 of the main clamp 230. As shown in FIG. 14, the flow locking part 250 includes a locking part body 251 and a plunger-shaped fixing pin 255 that can be protruded from one side of the locking part body 251 (see arrow C). , It includes a handle 252 and a handle fastener 254 for protruding and protruding the fixing pin 255.

The flow lock unit 250 configured in this way operates, for example, as follows. When the handle 252 is pushed into the lock body 251 (refer to arrow B), the fixing pin 255 protrudes from the lock body 251, and in this state, the handle 252 is rotated clockwise. (See arrow A) The protrusion 253 formed on the handle shaft is fitted into the groove of the handle fastener 254 so that the handle 252 is kept pressed, and the fixing pin 255 is maintained in a protruding state. If it operates in the opposite direction (that is, when the handle 252 is rotated counterclockwise and then pulled, the fixing pin 255 enters the locking body 251).

On the other hand, the flow locking part 250 is a main clamp to be inserted into the fixing pin hole 217 (see FIG. 11) formed on one side of the fixing plate 211 of the fixing support 210 described above when the fixing pin 255 protrudes. It is fixed to the lower clamp 231 of 230. Therefore, in a state in which the fixing pin 255 protrudes and is inserted into the fixing pin hole 217, the main clamp 230, the flow support 220 connected thereto, and the auxiliary clamp 260 are fixed to the fixing plate 211 to flow. It becomes impossible.

The main clamp 230 is a member that wraps and clamps the hose 20, more precisely, the two flanges 22 and 25, which are the connecting portions of the hose-side connector 21 and the hose portion in the hose 20, and largely the lower clamp 231 ), and an upper clamp 232, and a rotation shaft 233.

The lower clamp 231 and the upper clamp 232 have an arcuate structure in which one end of each is rotatably connected by a rotation shaft 233. Therefore, when holding the handle 234 attached to the upper clamp 232 and opening the upper clamp 232, as shown in FIG. 12, the clamp 230 is opened and the inner peripheral surface of the exposed lower clamp 231 body And when the two flanges (22, 25; see Fig. 4) of the hose 20 are seated in the seating space defined by the side plates 2311 and 2312, and the upper clamp 232 is closed again, the main clamp 230 is It can be clamped by wrapping the outer peripheral surface of the two flanges (22, 25) of the hose (20).

At this time, the flanges 22 and 25 of the hose 20 clamped by the main clamp 230 are standardized in diameter and thickness, but the thickness of the gasket (not shown) inserted between the two flanges 22 and 25 Depending on the degree of tightening of the bolt 27 and the nut 28, or by the use or tolerance of non-standard products (especially the hose side flange 22), the total thickness of the two flanges 22, 25 is clamped ( 231, 232) may be larger or smaller than the width (length in the Y-axis direction) of the seating space defined by the inner circumferential surface of the body and both side plates 2311, 2312; 2321, 2322. Therefore, it is preferable that the seating space has a structure that can be dynamically variable with a certain margin.

To this end, the main clamp 230 of the present embodiment, as shown in Figure 13, both the upper and lower clamps (231, 232), both side plates (2311, 2312; 2321, 2322) the spacing between the spring 240 Accordingly, it has a structure that varies according to the total thickness of the two flanges 22 and 25. On the other hand, the connecting pins 241 connecting both side plates 2311, 2312; 2321, 2322 through the upper and lower clamps 231, 232 body, the both side plates 2311, 2312; 2321, 2322 are not twisted to each other. Both side plates 2311, 2312; 2321, 2322 are connected so that the spacing is variable. That is, both ends or one end of the connection pin 241 advance and retreat into the holes formed on the opposite inner surfaces of both side plates 2311, 2312; 2321, 2322, so that both side plates 2311, 2312; 2321, 2322 are not twisted together. It can be moved only in the Y-axis direction.

In addition, so that the two flanges (22, 25) of the hose (20) can be smoothly inserted and seated in the seating space, the opposite inner surfaces of both side plates (2311, 2312; 2321, 2322) are chamfered or rounded. A seating guide 239 is formed.

Meanwhile, reference numeral 238, which is not described, is a knurling pad that holds the two flanges 22, 25 of the hose 20 so that they do not slide or rotate on the inner circumferential surface of the body of the main clamp 230. In addition, although not shown, the upper and lower clamps 231 and 232 are opened when the upper and lower clamps 231 and 232 are closed at the ends of the upper and lower clamps 231 and 232 that are not connected by the rotation shaft 233 A fastening means such as a hook clamp that locks to prevent it is attached. This fastening means is also applied to the auxiliary clamp 260 to be described later.

Meanwhile, the main clamp 230 is not directly related to the clamping function, but the following configuration is added to prevent erroneous connection between the hose 20 and the coupler unit 10.

First, a hose seating sensor 242 is attached to the main clamp 230 so that subsequent work does not proceed without mounting and fixing the hose 20 to the hose clamping unit 200. Specifically, the hose seating sensor 242 is attached to one side plate 2311 of the lower clamp 231, as shown in FIG. 12, and when the hose 20 is seated in the seating space, the hose-side connector ( 21) may be implemented as a contact sensor that senses that the hose 20 is seated by contacting the outer circumferential surface. Of course, the type and attachment position of the hose seating sensor 242 are not limited thereto, and for example, an optical sensor made of a pair of a light-emitting element and a light-receiving element can be used, and the attachment position is also within the seating space of the lower clamp 231 or It may be an upper clamp 232.

Next, a key code alignment jig 243 is attached to the main clamp 230. As described with reference to Fig. 4, the hose-side connector 21a is provided with a unique key code 23 according to the type of chemical supplied by the hose 20a, and the coupler-side connector ( 13a) is also provided with a confirmation key code (not shown) corresponding to the key code 23. Therefore, if the key code 23 and the confirmation key code do not match each other, the hose-side connector 21a and the coupler-side connector 13a are not fastened, thereby preventing an accident of supplying an incorrect chemical. By the way, as mentioned above, the key code 23 and the key code for confirmation must be aligned in the correct position corresponding to each other (typically, the uppermost part in the Z-axis direction). Accordingly, in this embodiment, a means for aligning the key code 23 of the hose-side connector 21a is provided in the main clamp 230a, and if the key code is not aligned in the correct position, a subsequent operation, that is, the hose 20a ) Can be prevented from moving forward in the Y-axis direction.

In this embodiment, the key code alignment means includes a key code alignment jig 243 and an alignment check sensor 249.

The key code alignment jig 243 is made of a substantially flat arcuate jig plate 2431 parallel to a plane perpendicular to the Y-axis (XZ plane), as shown in FIG. 10 and the like. A jig rod 246 is attached to one end of the jig plate 2431, which is perpendicular to the surface of the jig plate and extends to the rear of the Y axis. The jig rod 246 is slidably inserted through the hole of the jig bracket 248, and the jig bracket 248 is fixed in the vicinity of the rotation shaft 233a of the main clamp 230a, so that the key code alignment jig 243 ) Is attached to the main clamp 230a. On the other hand, a sliding stopper 247 is attached to the rear end of the jig rod 246 to prevent the jig rod 246 from being separated from the jig bracket 248 by moving forward in the Y axis.

Further, the key code alignment jig 243 can be rotated within the XZ plane with the jig rod 246 as a central axis (see Fig. 12), and a rotation stopper 2432 for regulating the rotation range is provided. That is, the rotation stopper 2432 is similar to the jig rod 246 in the vicinity of the end opposite to the end to which the jig rod 246 of the jig plate 2431 is attached, and has a length similar to that of the jig rod 246 to the rear of the Y axis. Is extended. Therefore, when the key code alignment jig 243 is rotated in a direction closer to the main clamp 230a around the jig rod 246, the rotation stopper 2432 is caught on the upper surface of the upper clamp 232a and no longer rotates. By making it impossible, the rotation range of the key code alignment jig 243 is regulated. In addition, when the upper clamp 232a is rotated around the rotation shaft 233a to open the main clamp 230a, the rotation stopper 2432 is caught on the upper surface of the upper clamp 232a, and the key cord alignment jig 243 is also It is opened by rotating together with the upper clamp 232a.

In addition, a key code for alignment 244 corresponding to the key code 23 formed on the hose-side connector 21a on the side in the arch in the vicinity of the end opposite to the end to which the jig rod 246 is attached of the jig plate 2431 Is formed. The alignment key code 244 is formed at the hose-side connector in a state in which the key code alignment jig 243 is rotated around the jig rod 246 to the end of the rotatable range in a direction closer to the main clamp 230a. It is a position facing the top of 21).

Meanwhile, an alignment check sensor 249 is attached to the upper surface of the upper clamp 232a. The alignment check sensor 249 may be implemented as a contact sensor, and the key code alignment jig 243 slides backward in the Y-axis so that the sensor facing portion 245 of the jig plate 2431 is attached to the alignment check sensor 249. They are aligned and attached to the location where they come into contact. Of course, the alignment check sensor 249, like the above-described hose seating sensor 242, is not limited in its type and attachment position as illustrated.

According to the key code alignment means configured as described above, the main clamp (the key code 23 of the hose-side connector 21a) faces upward in the Z axis in a state where the key code alignment jig 243 is moved forward on the Y axis. After seating and clamping the hose (20a) on 230a), rotate the key code alignment jig (243) around the jig rod (246) in the direction closer to the main clamp (230a) to the end of the rotatable range, and align the key code. When the jig 243 is retracted to the rear of the Y-axis, the alignment key code 244 portion of the key code alignment jig 243 contacts the upper surface of the hose side connector 21a, while the key code of the hose side connector 21a ( 23), the sensor facing portion 245 of the jig plate 2431 contacts the alignment check sensor 249, thereby completing the key code verification. At this time, the hose (20a) is not aligned so that the key code (23) of the hose side connector (21a) is located at the top, or the key code (23) of the hose side connector (21a) and the key code (244) for alignment match If it is not (joined), the key code for alignment 244 is caught on the outer circumferential surface of the hose-side connector 21a or is caught by the key code 23 of the hose-side connector 21a and the key code alignment jig 243 is no longer retracted. Accordingly, the sensor facing portion 245 cannot contact the alignment check sensor 249.

The auxiliary clamp 260 clamps the hose part in order to prevent the hose part behind the hose side flange 22a of the hose 20a from sagging down and to prevent the hose 20a from swinging during the supply of chemicals. As to, similar to the main clamp 230, it is made of a lower clamp 261, an upper clamp 262, a rotation shaft 263, a handle 264, and the like. Since the detailed configuration and operation of the auxiliary clamp 260 is similar to that of the main clamp 230, a detailed description will be omitted.

On the other hand, in the above-described embodiment, the space in which the hose mounting/transporting devices 100 and 200 are arranged is a space between the opening 2 and the coupler unit 10 spaced apart from the opening 2 (S1). ), and a space S2 formed by recessing the coupler unit housing 12, but the present invention is not limited to this embodiment. That is, the space in which the hose mounting/transporting devices 100 and 200 are disposed is i) the coupler unit housing 12 is not recessed (there is no space S2), so that the opening 2 and the space ( S1), or ii) the coupler unit 10 is in close contact with the inner surface of the outer wall (L=0 in FIG. 2, and the space S1 does not exist), thereby being composed of the opening 2 and the space S2, or iii) Since neither the space (S1) nor the space (S2) exists, it is composed only of the opening 2, or further iv) the coupler unit 10 is disposed outside the building (in FIG. 2, the outer wall (with t=L=0) 1) and space (S2) does not exist), it may be formed only with space (S2). However, in any of the cases i) to iv), the depth of the space in which the hose mounting/transfer devices 100 and 200 are disposed (length in the Y-axis direction) may be the hose mounting/transfer devices 100 and 200. It is set to a size.

In addition, in the above-described embodiment, the caps of the hose-side connector 21 and the coupler-side connector 13 are removed, and the hose-side connector 21 and the coupler-side connector 13 are connected manually by an operator. However, the present invention is applicable even when a means for automatically removing the cap is provided as in Patent Document 1.

Next, an operation of connecting/separating the hose 20 to the coupler unit 10 by the operator using the system according to the present embodiment as described above will be described.

The work performed by the worker using this system is largely: (a) the work of the first worker mounting and fixing the hose 20 to the hose mounting/transfer device 100, 200 outside the building, and (b) the building In the inner space (S1), the second operator removes the caps of the hose-side connector 21 and the coupler-side connector 13, and connects the hose-side connector 21 and the coupler-side connector 13 do.

Specifically, in the operation of (a), the first worker (tank lorry driver) from the outside of the building pulls the hose transfer unit 100 including the hose guide 106 and the hose clamping unit 200 toward itself to mount the hose. / Makes the transfer device (100, 200) in a convenient state for mounting and fixing the hose 20 (the state without the hose 20 in Fig. 8). At this time, the pair of latches 125 of the above-described lower sliding table 120 is in a lowered state by the lifting means 126, and the lower sliding table 120, the upper sliding table 130, and the hose clamping unit ( 200) makes it possible to move independently of each other. In addition, at this time, the first worker may work without wearing a fireproof suit.

Subsequently, the first operator opens the upper clamps 232 and 262 of the main clamp 230 and the auxiliary clamp 260 as shown in FIG. 12, and the two flanges 22 and 25 of the hose 20 are main Each lower side of the main clamp 230 and the auxiliary clamp 260 so that the hose 20 is seated in the seating space defined by the body inner circumferential surface of the lower flange 231 of the clamp 230 and both side plates 2311 and 2312 The clamps 231 and 261 and the hose receiving portion 224 of the flow support 220 and the hose guide 106 are placed on it. At this time, the key code alignment jig 243 is kept in a state of being advanced forward of the Y axis as shown in FIG. 12. On the other hand, the hose side connector 21 at the front end of the hose 20 is kept covered with a cap (not shown), and the key code 23 formed on the outer circumferential surface of the hose side connector 21a faces upward the Z axis. .

Subsequently, the first operator closes the upper clamps 232 and 262 of the main clamp 230 and the auxiliary clamp 260. In addition, the key code alignment jig 243 is also rotated in the same direction as the upper clamps 232 and 262, so that the alignment key code 244 is aligned with the key code 23 of the hose-side connector 21a. Subsequently, the first operator retracts the key code alignment jig 243 to the rear of the Y axis. Then, when the key code 23 of the hose-side connector 21a and the key code 244 for alignment are aligned and matched (mating), the sensor facing portion 245 contacts the alignment check sensor 249 to obtain a key code. The alignment of is confirmed. On the other hand, when the key code 23 of the hose-side connector 21a and the key code 244 for alignment are not aligned or do not match (mating), the alignment key code 244 is The key code alignment jig 243 can no longer be retracted by being caught on the outer circumferential surface or the key code 23, and thus the sensor facing portion 245 does not contact the alignment check sensor 249, so that the operator cannot align the key code. It can be seen that the hose 20a is not installed or is incorrect.

Subsequently, the first operator moves the hose transfer unit 100 including the hose guide 106 and the hose clamping unit 200 to the front of the Y-axis to the original position, and then a pair of latches 125 of the lower sliding table 120 ) Is raised by the lifting means 126 to engage with the clasp 205, so that the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are simultaneously advanced toward the coupler unit 10. Make it possible.

In the operation of (b), the second operator checks whether the correct hose 20 is properly mounted and fixed to the hose mounting/transfer devices 100 and 200, and if there is no problem, the hose-side connector 21 and the coupler-side connector (13) Remove each cap and connect the hose-side connector (21) and the coupler-side connector (13).

Specifically, the second operator turns on the driving switch (not shown) to operate the sliding drive unit 110 to advance the sliding tables 120 and 130 and the hose clamping unit 200 toward the coupler unit 10. At this time, since the pair of latches 125 of the above-described lower sliding table 120 is raised by the lifting means 126, the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 ) Can advance toward the coupler unit 10 at the same time.

On the other hand, at this time, when the seating of the hose 20 or the alignment of the key code is not detected by the hose seating sensor 242 and the alignment check sensor 249, the sliding drive unit 110 is prevented from operating even if the drive switch is pressed. I can.

When the hose 20 is seated and the key code aligned is normally performed, and the sliding tables 120 and 130 and the hose clamping unit 200 are moved to the maximum by the sliding driving unit 110, the latch of the lower sliding table 120 When (113) advances to the front stopper 114), the sliding drive unit 110 stops the operation.

Then, the second operator removes the cap of each of the hose-side connector 21 and the coupler-side connector 13, and lowers the pair of latches 125 of the lower sliding table 120 by the lifting means 126. After making the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 movable independently from each other, the hose clamping unit 200 is further manually advanced (Fig. 7(b)). State) Connect the hose-side connector (21) and the coupler-side connector (13). Until this time, the flow locking unit 250 maintains a locked state, that is, a state in which the fixing pin 255 is inserted into the fixing pin hole 217.

Thereafter, the flow lock unit 250 is switched to the unlocked state, and chemical supply is started.

When the chemical supply is complete, the hose 20 and the coupler unit 10 are separated from the above-described order and the coupler unit 10 is removed, and the hose 20 is removed from the system.

As described above, in the method of the present embodiment, since the second worker wearing a fireproof suit works manually or semi-automatically in the connection/separation space (S1) between the hose 20 and the coupler unit 10, errors or defects in various devices Even if the system malfunctions due to various reasons, such as, it is possible to respond immediately, thereby preventing a chemical spill.

On the other hand, the hose mounting and fixing of the above-described (a) operation is performed by the first operator, and (b) the connection of the hose-side connector 21 and the coupler-side connector 13 of the operation is performed by a second operator, ( The key code alignment work, which is the work between the work a) and (b), and the work of advancing the hose fixed to the hose mounting/transfer device toward the coupler unit may be performed by the first worker or the second worker.

In the above, although the present invention has been described by a limited embodiment and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be described by those of ordinary skill in the art to which the present invention pertains.
