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 specifically, a chemical supplied from a chemical supply source, such as a tank lorry, through a hose to the inside of a semiconductor factory or a chemical factory building. It relates to a connection / disconnection system between a hose and a building side coupler unit for supply.

Various types of chemicals are used in large quantities in semiconductor factories and chemical factories. Here, the chemical includes liquid substances such as hydrofluoric acid, sulfuric acid, hydrochloric acid, ammonia, hydrogen peroxide, plating solution, photoresist, and developer, and paste-like substances such as slurry used for chemical mechanical polishing (CMP).

These chemicals often have toxicity or flammability that is harmful to the human body or the environment, and are stored in containers such as tanks or drums, transported to a tank lorry or truck, and supplied to a factory. On the other hand, high cleanliness is often required in such factories.

Therefore, when supplying the chemical transported in this way to a semiconductor factory or a chemical factory, a coupler unit is provided that is isolated from the production facility and connected to a chemical storage tank in the factory, and a chemical supply hose is connected to the coupler unit to supply 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 the chemical supply hose (hereinafter also simply referred to as a 'hose') and the chemical storage tank.

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

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

The connection of the coupler unit and the hose configured in this way is performed by an operator (typically an operator of the tank lorry) aligning the male and female connectors, then removing the male and female caps, and engaging the male and female connectors.

However, as described above, since these chemicals are harmful to the human body or the environment, care must be taken to prevent accidents such as chemical leakage or exposure of workers to chemicals when connecting / disconnecting hoses and coupler units. Must wear fire resistant clothing. However, it is very troublesome for the operator (tank lorry operator) to wear and take off the fire resistant clothing, but the worker inside the factory (clean room) wearing the fire resistant clothing comes out of the factory to connect / disconnect the hose and coupler unit. Not only is it more cumbersome, but it may be practically impossible, especially depending on weather conditions.

As described above, since the connection / disconnection of the hose and the coupler unit is a very cumbersome and dangerous operation, the automation thereof has recently been promoted (for example, see Patent Document 1). The automatic tightening system between the chemical tank lorry disclosed in Patent Document 1 and the ACQC unit is provided with a separate clean booth and frame 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). It is equipped with a hose holder (movable unit) that can move back and forth toward the ACQC unit (female connector), a cap removal means that can automatically remove the cap of each male and female connector, and a transfer unit that drives the hose holder back and forth toward the female connector. do.

According to the fastening system of Patent Document 1, if the operator (tankrori operator) simply mounts and fixes the hose in the state where the cap is fastened to the hose holder, the cap of the male and female connector is removed, and the female connector is moved to the female connector of the hose holder. Hose (male connector) is automatically connected to the connector, so it is possible to safely connect the hose and the ACQC unit, and the operator does not need to wear fire resistant clothing.

However, as shown in FIG. 4, the hose 20a has a considerable weight because it includes metal flanges 22a, 25a and a 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 means that the female connector of the coupler unit is directly exposed to the environment outside the building. The purpose is to secure a space for placement and movement of a hose holder, etc., to stably mount and fix the hose during the chemical supply after connecting and connecting the male and female connectors.

Therefore, the worker lifts the heavy hose and pushes it to the inside of the space, so it is not easy and uncomfortable to mount and fix it accurately on the hose holder, there is a possibility of misalignment, and it can be a burden on the body such as the waist of the worker.

And a perspective view, and FIG. 4 is a perspective view showing a hose connected to the coupler unit by the system. Referring 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 mount / transfer devices 100, 200a, 200b.

Meanwhile, the system includes two hoses 20a, 20b, and accordingly, the coupler unit 10 also includes two coupler-side connectors 13a, 13b that are connected / disconnected to the two hoses 20a, 20b, respectively. 2 hose clamping units 200a so that the hose mounting / transfer devices 100, 200a, 200b can also connect / disconnect two hoses 20a, 20b to respective coupler-side connectors 13a, 13b , 200b). Here, the first hose 20a and the first coupler-side connector 13a are configured for supplying chemicals from a chemical supply source outside a building (factory), such as a tank lorry, to a chemical storage tank (not shown) or a production facility inside the building. , And the second hose 20b and the second coupler-side connector 13b use 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 structure to supply from the inside of the building (factory) to the chemical supply outside the building. That is, the inert gas is blown into the chemical source through the second hose 20b which is the inert gas hose so that the chemical is smoothly discharged to the first hose 20a that is the chemical supply hose.

These two hoses (20a, 20b), two coupler-side connectors (13a, 13b) and two hose clamping units (200a, 200b), the basic configuration between the elements of the pair are the same and similar, mainly in the following first The elements (elements with 'a' in the reference sign) are explained, and detailed descriptions of the second elements (elements with 'b' in the reference sign) are omitted except for differences from the first element. . In addition, in the following, it is not necessary to distinguish between the first element and the second element, or when referring together, 'a', 'b' are omitted from the reference numeral and only numbers are indicated.

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

The coupler unit 10 is disposed at a predetermined distance (L) away from the building exterior wall 1 in the building, facing the opening 2 formed through the exterior wall on a part of the exterior wall 1 of the building. In this embodiment, the coupler unit 10 is implemented in the form of a booth 11 having an internal 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 penetrates the housing 12 recessed in the Y-axis direction to expose the outside space S2 of the booth 11 to face the hose 20, and the other end is inside the booth 11 Is connected to a chemical storage tank (not shown) or a production facility (not shown) through a pipe, a valve, and the like. One end of the coupler side connector 13 exposed to the outside of the booth 11 is covered with a cap 14 to prevent chemical leakage and foreign matter inflow. 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. A lever 15 is provided to prevent this.

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

In order to prevent incorrect connection between the hose 20a and the coupler unit 10, the hose side connector 21a has 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 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 with a predetermined angle along the circumferential direction on the outer circumferential surface of the hose-side connector 21a and the inner circumferential 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 and the key code for confirmation, but also have to be aligned to the corresponding positions of both to achieve mutual fastening. It is possible. A detailed alignment method of the key code 23 and a jig therefor will be described later.

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

Referring again to FIGS. 1 to 3, the hose mounting / transfer devices 100 and 200 include an opening 2 formed in the building outer wall 1 and a space between the opening 2 and the coupler unit 10. It is arranged in (S1), and is configured to be able to move back and forth in the Y-axis direction toward the coupler unit 10 by mounting and fixing the hose 20. Particularly, the hose-side connector 21 and the coupler-side connector 13 are connected to the coupler unit 10 and the hose mounting / transfer devices 100 and 200 when the hose 20 is advanced toward the coupler unit 10. It is positioned and arranged to be possible.

As described above, in this embodiment, the coupler unit 10 is disposed inside the building spaced apart from the exterior wall 1 of the building facing the opening 2 formed through a part of the exterior wall 1 of the building, and the hose mounting / transfer 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) is mounted and fixed to the hose mounting / transfer devices 100 and 200 through the opening 2 outside the building, in the space S1 inside the building. A second worker (worker inside the factory) can remove the cap 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, the first worker is not exposed to the chemical (because the caps are covered on each connector 13 and 21), so there is no need to wear cumbersome fire resistant clothing. On the other hand, since the second worker is likely to be exposed to the chemical (removing and removing the cap of each connector), the second worker should wear a fire resistant suit. However, since the second worker does not go out of the building wearing a fire resistant suit, the hassle of the conventional method is much less. In particular, if the second worker is already wearing a fire resistant garment inside the building, the hose 20 can be connected / disconnected to the coupling unit 10 by simply moving inside the building.

At this time, when the second worker is working inside the normal space (S3) is a space where high cleanliness is required, such as a clean room, this inner space (S3) and the hose mounting / transfer device (100, 200) are arranged ( S1) is preferably isolated. To this end, these two spaces (S1, S2) are isolated by the building inner wall (3) and the door (4) as shown in Figure 1, more preferably, the interior space (S3) by maintaining a positive pressure door ( 4) When the hose mounting / transfer devices 100 and 200 are opened, air may not be introduced into the interior space S3. Furthermore, by installing an air curtain or an air shower in addition to the door 4 between the two spaces S1 and S3, a second worker wearing a fire resistant garment removes foreign substances such as dust adhering from the space S1 and internally. It can be allowed to enter the space (S3). In addition, the door 30 is installed in the opening 2, and when the system is not in use, the door 30 can be closed to prevent outside air from entering the space S1.

Meanwhile, each component of the system of the present embodiment is disposed in consideration of ergonomics. The hose 20, in particular the first hose 20a, has a considerable weight since it comprises metal flanges 22, 25 and a connector 21. Accordingly, each component of the system of the present embodiment is arranged such that the first or second operator handling this heavy weight can work without bending the waist or raising the arm. Specifically, as shown in FIGS. 1 and 2, the height (H1) from the ground to the lower surface of the opening (2), which is the height at which the hose mounting / transfer devices (100, 200) are installed, is about 800 to 1000 mm, The height H2 of the opening 2 is about 400 to 600 mm, and the width W of the opening 2 can be about 600 to 1000 mm. In addition, the length (L) of the space (S1) in the Y-axis direction may be about 600 to 1000 mm so that the second worker can work by approaching the hose mounting / transfer devices 100 and 200. On the other hand, 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 length (L) of the space (S1) in the Y-axis direction may be adjusted according to the thickness (t) of the outer wall (1) and the length of the Y-axis of the hose mounting / transfer devices (100, 200).

On the other hand, elements shown by reference numerals 40 and 41 in FIGS. 2 and 3, the hose mounting / transporting devices 100 and 200 are stably installed on the bottom surface of the opening 2 to support the pedestal 40 so as to maintain the level. And height adjuster 41. In this case, when the hose mounting / transfer devices 100 and 200 in FIG. 2 are applied to the lower surface of the recessed space S2 of the coupler unit 10 and the lower surface of the opening 2, the pedestal 40 may be omitted. 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 the lower surface of the space (S2) and the lower surface of the opening (2). In case of striking over, it is also possible to omit both the pedestal 40 and the height adjuster 41.

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

First, FIG. 5 is a perspective view of the hose mounting / transporting devices 100 and 200, FIG. 6 is an exploded perspective view showing some components omitted, and FIG. 7 is a view of the hose transporting unit 100 of the hose mounting / transporting device. 8 is a schematic side view for explaining the operation, and FIG. 8 is a side view of a system showing a state in which the hose transfer unit 100 of the hose mounting / transfer device 100, 200 is withdrawn to the exterior wall 1 side (backward) as much as possible. to be. The elements not shown in FIG. 6 are elements 102b, 103b, 106b, 120b, 130b, 200b for mounting and conveying the second hose 20b, and some covers 111, 136, and 137.

5 and 6, the hose mounting / transfer device 100, 200 is large, the hose clamping unit 200 for clamping by mounting the hose, and the hose clamping unit 200 toward the coupler unit 10 It is equipped with a hose transfer unit 100 that is mounted to be able to transfer (retreat).

The hose transfer unit 100 includes a base table 101, a hose guide 106, a sliding driving unit 110, a lower sliding table 120, and an upper sliding table 130. The double base table 101 and the sliding driving unit 110 are provided with one common to the first hose 20a and the second hose 20b, and the lower sliding table 120 and the upper sliding table 130 are first For each of the hose 20a and the second hose 20b, one pair is provided on the left and right sides of the sliding drive unit 110.

The base table 101 is seated on the above-described opening 2 and the height adjusting device 41, on which all the components of the hose transfer unit 100 are installed. Specifically, on the base table 101, the sliding drive unit 110 is fixedly arranged along the Y-axis direction in the center portion, and is paired on the left and right sides of the sliding drive unit 110 to guide the storage unit 105 and the guide rail 104 ) Is fixedly placed. In the guide storage section 105, a draw rod 107 connected to the hose guide 106 is accommodated so that the hose guide 106 can be drawn / drawn in the Y-axis direction (see FIG. 8). On the guide rail 104, the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are sequentially and slidably installed in the Y-axis direction, respectively. In addition, a side cover 102 is provided at both ends of the base table 101 in the X-axis direction to cover the side surface of the hose transfer unit 100.

The sliding drive unit 110 includes a fixed portion 117 fixed on the base table 101, a movable portion 112 sliding in the Y-axis direction, and stoppers 114, 115 that define a moving range of the movable portion 112. ), And a driving unit cover 111 covering them (see FIG. 5). A linear drive means such as a linear motor or a rodless cylinder is built in the fixed part 117 to slide the movable part 112. Both ends of the movable part 112 in the X-axis direction are formed with a U-shaped clasp 113 projecting outwardly from the movable part 112.

On the other hand, on the side of the movable portion 112 of the lower sliding table 120, the one-shaped clasp 122 is protruded toward the clasp 113 at the same height as the clasp 113 and inserted into the central groove portion of the clasp 113 Is formed. Therefore, 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 unit 112 in the Y-axis direction.

At this time, the locking range of the stopper 113 is limited by the stoppers 114 and 115, and accordingly, the range of sliding (retreat) of the lower sliding table 120 is also restricted. The stoppers 114 and 115 may be implemented as, for example, a limit switch to stop driving of the movable part 112 when the clasp 113 contacts. FIG. 6 shows the state in which the latch 113 has moved to the front stopper 114, and 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.

FIG. 8 shows the state in which the stopper 113 has moved to the rear stopper 115, 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 is retreating to the outside of the outer wall 1 of the building. In addition, the upper sliding table 130 is retracted more than the lower sliding table 120, so the hose clamping unit 200 thereon is also exposed out of the opening 2, and furthermore, the hose guide 106 is also opened ( 2) It is withdrawn (retracted) out. The hose guide 106 can be pulled out by the first operator pulling the hose guide 106 toward itself without a separate driving means in this embodiment. Meanwhile, the forward and backward mechanisms 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 may be retracted more than the lower sliding table 120, although not shown in FIG. 6, the upper sliding table 130 and the hose clamping The unit 200 may be further advanced toward the coupler unit 10 than the lower sliding table 120,

As such, when the lower sliding table 120, the upper sliding table 130, the hose clamping unit 200, and the hose guide 106 are drawn out (retracted) out of the opening 2, the first operator may disconnect the hose 20. It is easier to mount and fix on the hose mounting / transfer devices (100, 200). In addition, when the lower sliding table 120, the upper sliding table 130, and the hose clamping unit 200 are more advanced than the front end of the base table 101, the second worker connects the hose 20 to the coupler unit 10 ) Makes it easier to connect / disconnect.

Referring back to FIG. 6, a guide rail 124 is fixedly arranged 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 arranged on the upper surface of the upper sliding table 130, and the clamp base plate 201 on which the hose clamping unit 200 is fixed on the guide rail 134 is along the Y-axis direction. It is slidably installed. Therefore, the lower sliding table 120, the upper sliding table 130 and the hose clamping unit 200 can be moved back and forth in the Y-axis direction independently or interlocked with each other, and the upper sliding table 130 and the hose clamping unit 200 ), It is possible to move back and forth beyond the end of the lower sliding table (120).

On the other hand, in the present embodiment, the lower sliding table 120, the upper sliding table 130 and the hose clamping unit 200 can move back and forth in the Y-axis direction independently or interlocked with each other, but with a certain section (for example, two stoppers 114 , 115) section, it may be desirable that the lower sliding table 120, the upper sliding table 130 and the hose clamping unit 200 move together. To this end, the lower sliding table 120, the upper sliding table 130 and the hose clamping unit 200 have similar configurations to the latch 113 of the above-described sliding drive unit 110 and the latch 122 of the lower sliding table 120. ).

Specifically, in this embodiment, as shown in FIG. 6, a pair of fasteners 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. In order to provide a latch 205 that is inserted between the pair of latches 125 is 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 engaged state of the pair of clasps 125 and clasps 205 is required. To this end, in this embodiment, the pair of clasps 125 are configured to be elevated by the lifting means 126, and when the pair of clasps 125 rise, the clasp 205 engages with the sliding table 120 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, for example, by a hydraulic cylinder, a solenoid plunger, a toggle latch, or the like.

On the other hand, when the pair of latches 125 are raised by the lifting means 126, as a result of the independent movement of the lower sliding table 120 and the hose clamping unit 200, the latch 205 is a pair of latches ( 125) If it is located in a position that cannot be engaged between, the rising clasp 125 and the clasp 205 do not collide or mesh with each other, so that the lower sliding table 120 and the hose clamping unit 200 cannot be moved together. . In order to prevent this, in this embodiment, a latch detection sensor 127 is provided between a pair of latches 125, so that even if an operator operates the lift means 126, the latch detection sensor 127 has a latch 205 thereon. ) Is not detected, the operator is warned through a warning sound or the like and the lifting means 126 is not operated. The clasp 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, as shown in (a) of FIG. 7, wire fixtures 153 and 155 to which the wires 151 are fixed are provided on the upper surface of the lower sliding table 120 and the lower surface of the clamp base plate 201, respectively. And, by installing a pair of rollers 152 in the wire holes 135 formed at both ends of the upper sliding table 130 in the Y-axis direction, the pair of rollers 152 and the two wire fixtures (153, 155) The connecting wire forms a loop.

Accordingly, when the pair of latches 125 and the clasps 205 described above are engaged in the state shown in FIG. 7 (a), even if the lower sliding table 120 is driven back and forth by the sliding driving unit 110, the lower sliding table Not only the 120 but also the upper sliding table 130 and the clamp base plate 201 are moved back and forth at the same time, and the hose clamping unit 200 (clamp in the state that the pair of latches 125 and the clasps 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 portion of the clamp base plate 201 is moved by half the distance traveled. The table 130 moves following the clamp base plate 201. By doing in this way, the upper sliding table 130 and the clamp base plate 201 can be smoothly sliding, and the advanceable and retractable range of the hose clamping unit 200 can be stably extended.

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

Meanwhile, in the descriptions of FIGS. 6 and 7 and above, 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 clasp 125 and the clasp 205 so that the lower sliding table 120 and the upper sliding table 130 and hose Although the clamping unit 200 is implemented to move simultaneously or in conjunction with each other, this is changeable. That is, for example, a mechanism capable of engaging / disengaging between the lower sliding table 120 and the upper sliding table 130, or the lower sliding table 120 is simultaneously with both the upper sliding table 130 and the clamp base plate 201 Alternatively, a mechanism capable of selectively engaging / disengaging may be provided. Furthermore, in the above, the lower sliding table 120, the upper sliding table 130 and the clamp base plate 201 can be moved in cooperation with each other by using an interlocking mechanism such as a wire loop, but the interlocking mechanism may be omitted.

On the other hand, the pleated cover (136, 137) omitted in FIG. 6 covers the upper sliding table (130) before and after the clamp base plate (201), so that the upper sliding table (130) and the lower sliding table (from the chemical, etc.) 120) Protect your back. At this time, with the movement of the clamp base plate 201 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 is changed. To cope with the change, the wrinkle 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. However, depending on the application, one of the upper or lower sliding tables can be omitted and configured as one stage. . In addition, on the contrary, depending on the application, the sliding table may be configured in three or more stages.

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

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

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

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

The fixed support part 210 is made of a pair of fixed plates 211 and 212 which are opposed to each other and are erected and fixed to the clamp base plate 201. A pair of approximately rectangular fixed plates 211 and 212 are formed with large semi-circular large openings 216, each of which has an open top, and a plurality of large semi-circular small openings 213 are again formed in the large opening 216. Is formed. In addition, a plurality of recessed grooves 215 are formed on the inner surfaces of the pair of fixing plates 211 and 212 facing each other. In addition, a fixing pin hole 217 is formed on the outer surface of the fixing plate 211 on the main clamp 230 side of 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 unit 220 includes an approximately arch-shaped support block 221, a substantially semi-cylindrical hose accommodating portion 224 accommodating the hose 20 on its inner surface, and Y-axis end portions of the hose accommodating portion 224. It includes a pair of side plates 222 in the form of a substantially arch fixed to. Here, the length of the Y-axis direction of the hose receiving portion 224 is slightly larger than the length of the Y-axis direction of the support block 221, so that the Y-axis end of the support block 221 and the inner surface of the pair of side plates 222 The gaps are slightly spaced. The space between the Y-axis end of the spaced support block 221 and the inner surface of the pair of side plates 222 is connected by a connecting rod 223 made of an elastic material such as rubber, and the outer circumferential surface of the hose receiving portion 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 receiving portion 224 and both side plates 222 are fixed to the support block 221 to be able to flow to some extent. Meanwhile, a plurality of recessed grooves 225 are formed on the outer surface of the support block 221 in the Y-axis direction.

As described above, the flow receiving portion 220 in which the hose receiving portion 224 and both side plates 222 are fixed to be able to flow to the support block 221 to some extent is inserted into the large opening 216 of the fixing support portion 210. Then, as shown in FIG. 9, a pair of fixing plates 211 and 212 of the fixing support 210 is 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 220 is inserted into the small opening 213, so that the fixed support 210 and the flow support 220 are combined. At this time, the groove 215 of the fixed support 210 shown in FIG. 11 and the groove 225 of the flow support 220 face each other, and an elastic body such as a spring in a space formed by both grooves 215 and 225 (Not shown) is interposed. Accordingly, the flow support 220 is fixed to the fixed support 210 to be able to flow to some extent by the elastic rods (not shown) interposed in both 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 220, the lower clamps 231 and 261 of the main clamp 230 and the secondary clamp 260 are respectively connected by the connecting members 237 and 267. Is fixed. Accordingly, the main clamp 230 and the auxiliary clamp 260 are relatively movable relative to the fixed support 210 and the clamp base plate 201 together with the flow support 220 that is somewhat flowable.

The reason for configuring the main clamp 230 and the auxiliary clamp 260 to be flowable as follows 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 formed in a straight line and may be bent and arranged. 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 fluctuation may occur. Due to these various factors, even if the hose 20 is clamped by the hose clamping unit 200, the hose-side connector 21 may be eccentric or inclined relative to the coupler-side connector 13. Of course, the clamps 230 and 260 or the connectors 13 and 21 are provided with packings to cushion the shaking motion, eccentricity, inclination, etc., and maintain the sealing state, but the packing is deteriorated in shock, eccentricity, inclination, etc. that are repeated for a long time. An accident may occur in which the chemical leaks 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 to a certain degree by a flowable support 220, the hose-side connector 21 clamped to the clamp 230 swings, eccentrics, It is possible to significantly reduce the shock or asymmetric pressure that can accumulate in packings by adapting in real time to a slope or the like in real time.

On the other hand, the configuration in which the clamp (and consequently the hose-side connector 21) is flexibly supported has an effect of preventing an accident in which the chemical leaks or the connection of the connectors 13 and 21 is released, as described above. When connecting / disconnecting (13, 21) (especially when connecting), the alignment between the connectors 13 and 21 is misaligned due to the inclination or eccentricity of the hose-side connector 21, which may be a factor that makes the work uncomfortable. Therefore, it is necessary to lock the clamps (and consequently the hose-side connectors 21) so that the connectors 13 and 21 are not connected or disconnected.

To this end, in this embodiment, the hose clamping unit 200 includes a flow lock 250. Specifically, the flow lock 250 is fixed to the lower clamp 231 of the main clamp 230. 14, the locking part 250 includes a locking part body 251 and a fixing pin 255 in the form of a plunger that can be retracted from one side of the locking part body 251 (see arrow C). , This handle includes a handle 252 and a handle fixture 254 to hung the fixing pin 255.

The flow lock 250 configured as described above operates as follows, for example. When the handle 252 is pushed and pushed into the lock body 251 (see arrow B), the fixing pin 255 protrudes from the lock body 251, and when the handle 252 is rotated clockwise in this state, (See arrow A) The protrusion 253 formed on the handle shaft is inserted into the groove of the handle fixture 254, so that the handle 252 is kept pressed, and the fixing pin 255 is kept protruded. On the contrary, if it is operated (ie, the handle 252 is rotated counterclockwise and pulled, the fixing pin 255 enters the lock body 251).

On the other hand, the flow lock portion 250, the 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 above-described fixing support 210 when the fixing pin 255 protrudes It is fixed to the lower clamp 231 of (230). Therefore, when the fixing pin 255 protrudes and is inserted into the fixing pin hole 217, the main clamp 230 and the flow support 220 and the auxiliary clamp 260 connected thereto are fixed to the fixing plate 211 to flow. It becomes impossible.

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

The lower clamp 231 and the upper clamp 232 have an arcuate structure, one end of which is rotatably connected by a rotation shaft 233. Thus, holding the handle 234 attached to the upper clamp 232 and spreading the upper clamp 232, as shown in Figure 12, the clamp 230 is opened, the inner peripheral surface of the exposed lower clamp 231 body When the two flanges 22 and 25 of the hose 20 are seated in the seating space defined by the both side plates 2311 and 2312, and the upper clamp 232 is closed again, the main clamp 230 is The outer circumferential surfaces of the two flanges 22 and 25 of the hose 20 may be wrapped and clamped.

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) It may be larger or smaller than the width (Y-axis length) 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 varied with a certain margin.

To this end, the main clamp 230 of this embodiment, as shown in Figure 13, both the upper and lower clamps (231, 232), the gap between the two side plates (2311, 2312; 2321, 2322) to the spring 240 Therefore, it has a variable structure corresponding to the total thickness of the two flanges 22 and 25. On the other hand, the connecting pins 241 penetrating the body of the upper and lower clamps 231 and 232 to connect both side plates 2311, 2312; 2321, 2322, both side plates 2311, 2312; 2321, 2322 are distorted from each other The two side plates 2311, 2312; 2321, 2322 are connected so that the gap is variable. That is, both ends of the connecting pin 241 or both ends of the two side plates 2311, 2312; 2321, 2322 by advancing into the holes formed on the opposite inner surfaces of the two side plates, the two side plates 2311, 2312; 2321, 2322 are distorted from each other Instead, it can be moved only in the Y-axis direction.

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

Meanwhile, reference numeral 238 is a knurling pad that holds the two flanges 22 and 25 of the hose 20 so as not to slip or rotate on the inner circumferential surface of the main clamp 230. In addition, although not shown, the upper and lower clamps 231 and 232 open when the upper and lower clamps 231 and 232 are closed at the ends that are not connected by the rotation shaft 233 in the upper and lower clamps 231 and 232. A fastening means such as a hook clamp to prevent locking 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 an incorrect 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 the like, when the hose 20 is seated in the seating space, the hose side connector ( 21) by contacting the outer circumferential surface of the hose 20 may be implemented as a contact sensor for sensing that the seat. Of course, the type of the hose seating sensor 242 and the attachment position are not limited to this, for example, a light sensor composed of a pair of light emitting elements and a light receiving element can be used, and the attachment position is also inside the seating space of the lower clamp 231 or It can 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, a unique key code 23 is formed in the hose-side connector 21a according to the type of chemical supplied by the hose 20a, and the coupler-side connector ( Also in 13a), a key code (not shown) for confirmation corresponding to the key code 23 is formed. Therefore, if the key code 23 and the confirmation key code do not coincide with each other, the hose side connector 21a and the coupler side connector 13a are prevented from being fastened, thereby preventing an accident of supplying an incorrect chemical. By the way, as described above, the key code 23 and the key code for confirmation should be aligned in the correct position (typically, the uppermost part in the Z-axis direction) corresponding to each other. Accordingly, in the present 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, subsequent work, that is, the hose 20a ) Can be prevented from moving forward in the Y-axis direction.

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

The key code alignment jig 243 is composed 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. At one end of the jig plate 2431, a jig rod 246 that is perpendicular to the jig plate surface and extends behind the Y axis is attached. The jig rod 246 is slidably inserted into the hole of the jig bracket 248, and the jig bracket 248 is fixed to the pivot shaft 233a of the main clamp 230a, thereby making 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 Y-axis of the jig rod 246 to prevent the jig rod 246 from advancing toward the Y-axis and being separated from the jig bracket 248.

In addition, 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 is provided to regulate the rotation range. That is, the rotation stopper 2432 is a length similar to the jig rod 246 in the vicinity of the end opposite the end to which the jig rod 246 of the jig plate 2441 is attached, to the rear of the Y axis, similar to the jig rod 246. Is extended. Therefore, when the key code alignment jig 243 rotates in the direction of being close to the main clamp 230a around the jig rod 246, the rotation stopper 2432 is caught by the upper surface of the upper clamp 232a and is no longer rotated. By making it impossible, the rotation range of the key code alignment jig 243 is regulated. In addition, when the main clamp 230a is opened by rotating the upper clamp 232a around the rotation shaft 233a, the rotation stopper 2432 is caught on the upper surface of the upper clamp 232a, and the key code alignment jig 243 is also provided. It rotates with the upper clamp 232a to open.

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

On the other hand, an alignment confirmation sensor 249 is attached to the upper surface of the upper clamp 232a. The alignment confirmation sensor 249 may be implemented as a contact sensor, and the key code alignment jig 243 slides toward the Y-axis rearward, so that the sensor opposite portion 245 of the jig plate 2431 is connected to the alignment confirmation sensor 249. It is aligned and attached to the contact position. Of course, the alignment confirmation sensor 249, like the hose seating sensor 242 described above, is not limited in its kind and attachment position as shown.

According to the key code alignment means configured in this way, in a state in which the key code alignment jig 243 is advanced in the Y-axis forward direction, the main clamp (so that the key code 23 of the hose-side connector 21a faces the Z-axis upward) After mounting and clamping the hose 20a to 230a), the key code alignment jig 243 is rotated to the end of the rotatable range in the direction of approaching the main clamp 230a around the jig rod 246, and the key code alignment When the jig 243 is retracted to the rear of the Y-axis, the key code 244 of the hose-side connector 21a while the key code 244 for alignment of the key-code alignment jig 243 contacts the upper surface of the hose-side connector 21a ( After 23), the sensor opposing portion 245 of the jig plate 2431 contacts the alignment confirmation sensor 249, whereby key code verification is completed. 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 are matched. If not, the key code alignment jig 243 is no longer retracted because the alignment key code 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. Therefore, the sensor opposing portion 245 cannot contact the alignment confirmation sensor 249.

The auxiliary clamp 260 clamps the hose portion to prevent the hose portion 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 Similar to the main clamp 230, it consists of a lower clamp 261, an upper clamp 262, a rotating shaft 263, a handle 264, and the like. Since the specific configuration and operation of the auxiliary clamp 260 is similar to that of the main clamp 230, detailed description is omitted.

On the other hand, in the above-described embodiment, the space in which the hose mounting / transporting devices 100 and 200 are disposed, is a space S1 between the opening 2 and the coupler unit 10 spaced apart from the opening 2. ), And the coupler unit housing 12 is formed of a space S2 formed by being recessed, 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 opening 2 and the space (because the coupler unit housing 12 is not recessed (the space S2 does not exist)) S1), or ii) the coupler unit 10 is made of the opening 2 and the space S2 by closely contacting the inner surface of the outer wall (the space S1 is not present at L = 0 in FIG. 2), iii) Since both the space S1 and the space S2 do not exist, only the opening 2 is formed, or iv) the coupler unit 10 is disposed outside the building (in FIG. 2, the outer wall (t = L = 0) 1) and the space (S2 does not exist) may be made of only the space (S2). However, in any of the cases i) to iv), the depth (Y-axis length) of the space in which the hose mounting / transporting devices 100 and 200 are disposed may be arranged in the hose mounting / transporting devices 100 and 200. The size is set.

Further, 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 manually connected by an operator. However, the present invention is also applicable to a case in which a means for automatically removing a cap is provided as in Patent Document 1.

Subsequently, a description will be given of an operation in which an operator connects / disconnects the hose 20 to the coupler unit 10 by utilizing the system according to the present embodiment as described above.

The work performed by the operator using the present system is largely: (a) the first worker from outside the building mounts and fixes the hose 20 to the hose mounting / transfer device 100, 200; and (b) the building. In the interior 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) outside the building pulls the hose conveying unit 100 and the hose clamping unit 200 including the hose guide 106 toward itself to mount the hose. / Make 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 lowered by the lifting means 126, the lower sliding table 120, the upper sliding table 130 and the hose clamping unit ( 200) to be movable independently of each other. In addition, at this time, the first worker may work without wearing a fire resistant garment.

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 secondary clamp 260 is connected to the hose 20 so as to settle in a seating space defined by the body inner circumferential surface of the lower flange 231 of the clamp 230 and both side plates 2311, 2312. The clamps 231 and 261 are placed on the hose receiving portion 224 and the hose guide 106 of the flow support portion 220. At this time, the key code alignment jig 243 is left in a state of advancing forward of the Y axis as shown in FIG. 12. On the other hand, the hose side connector 21 of the front end of the hose 20 is maintained with a cap (not shown) covered, and the key cord 23 formed on the outer circumferential surface of the hose side connector 21a faces the Z axis upward. .

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 each of the upper clamps 232 and 262 to align the key code 244 for alignment with the key code 23 of the hose-side connector 21a. Subsequently, the first operator retracts the key code alignment jig 243 behind 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 (matched), the sensor opposing portion 245 contacts the alignment confirmation sensor 249 to obtain the key code. The alignment of is confirmed. On the other hand, if the key code 23 of the hose-side connector 21a and the key code 244 for alignment are not aligned or do not match (match), the key code for alignment 244 of the hose-side connector 21a The key code alignment jig 243 no longer retracts due to the outer circumferential surface or the key code 23, so that the operator does not contact the alignment confirmation sensor 249 and thus the key code alignment is not performed. It can be seen that an incorrect or incorrect hose 20a is mounted.

Subsequently, the first operator moves the hose conveying unit 100 and the hose clamping unit 200 including the hose guide 106 forward to the Y-axis, and then returns to the original position, and then a pair of latches 125 of the lower sliding table 120 ) By the lifting means 126 to engage the clasp 205, the lower sliding table 120, the upper sliding table 130 and the hose clamping unit 200 to advance toward the coupler unit 10 at the same time. Make it possible.

In the operation of (b), the second worker checks whether the correct hose 20 is properly mounted and fixed to the hose mounting / transfer device 100, 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 driving 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 be advanced toward the coupler unit 10 at the same time.

On the other hand, 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 confirmation sensor 249, the sliding driving unit 110 does not operate even when the driving switch is pressed. You can.

When the seating and key code alignment of the hose 20 is normally performed, and when the sliding tables 120 and 130 and the hose clamping unit 200 are advanced to the maximum by the sliding driving unit 110 (the latch of the lower sliding table 120) If (113) is advanced to the front stopper 114), the sliding drive 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 the lower sliding table 120 and the upper sliding table 130 and the hose clamping unit 200 are movable independently of each other, the hose clamping unit 200 is further advanced manually (of FIG. 7 (b)). State) Connect the hose-side connector 21 and the coupler-side connector 13. Until this time, the flow lock 250 maintains the locked state, that is, the fixed pin 255 is inserted into the fixed 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 completed, the hose 20 and the coupler unit 10 are removed in the reverse order to the above-described order, and the hose 20 is removed from the system.

As described above, in the method of the present embodiment, since the second worker wearing the fire resistant garment works manually or semi-automatically in the connection / separation space S1 of the hose 20 and the coupler unit 10, errors or defects of various devices Even if the system malfunctions for various reasons, etc., it can be dealt with immediately, thereby preventing chemical spills.

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