Description

TECHNICAL AREA

The present invention relates to a fluid control unit configured by coupling together a plurality of fluid control devices.

BACKGROUND

Typically, a piping system which interconnects a source of pressurized air (fluid supply source) and air actuated devices (fluid actuated devices) includes an air pressure circuit (fluid circuit) formed by a suitable combination of air pressure control devices (fluid control devices), such as a fluid pressure regulator. B. a filter device, a control device and a lubrication device is formed. The air pressure control units are controlled so that the air operated equipment operates smoothly. In the above-mentioned air pressure circuit, the air pressure control devices are connected to each other in parallel or in series, so as to supply compressed air from the fluid supply source z. B. split into several rivers, of which one river is relaxed and another filtered.

In the above air pressure circuit, pipes and fittings for connecting the fluid supply source and the air pressure control apparatuses with each other and connecting the air pressure control apparatuses with each other are used. Therefore, sealants used when pipes are connected to the pneumatic controllers and the terminals can penetrate. This can cause the air pressure controllers to malfunction. Also, an insufficient fastening force can lead to the escape of air. In piping systems using pipes, the cross-sectional area of the passages changes in a large number of parts. This increases the pressure loss.

In order to avoid such disadvantages, Patent Document 1 discloses a coupling unit which couples devices together. As in 21 the coupling unit U of patent document 1 is shown by a plurality of control elements (fluid control devices) 90 and fasteners 91 that with the controls 90 are formed. The controls 90 and the connecting elements 91 are coupled together, so that penetration of the sealant, insufficient fastening force and the number of parts whose passage cross-sectional area changes are reduced.

Especially every connecting element 91 is configured as a cubic block and has four outer wall surfaces or contact surfaces 91a , A through hole 92 is in the middle of each contact surface 91a designed. When the fasteners 91 coupled with each other, the through holes communicate 92 together. In every connecting element 91 owns each of the opposing surfaces that are not the contact surfaces 91a are, a part taken in 93 that of four side pieces 94 is surrounded. Three of the four side pieces 94 each have a semicircular window 95 and the remaining side piece 94 owns a threaded hole 96 ,

When the fasteners 91 be coupled with each other, the contact surfaces 91a the connecting elements 91 brought into contact. Then a bolt 97 in a semicircular window 95 one of the connecting elements 91 (the left in 21 ) and through the screw hole 96 of the other connecting element 91 (the right in 21 ) screwed. The head of the bolt 97 grabs the side pieces 94 of the left connector 91 such that the fasteners 91 be connected serially. This connects the through holes 92 the connecting elements 91 serial, forming a main passageway for compressed air. Then there is a control 90 with another contact surface 91a each connecting element 91 coupled. Accordingly, each control is 90 with the through hole 92 of the corresponding connecting element 91 connected so that compressed air is divided and to the respective controls 90 flows.

However, to fasteners 91 together in the connection unit U, the patent document 1 described, to connect, must have a contact surface 91a a connecting element 91 in which a semicircular window 95 is formed, and a contact surface 91a another connecting element 91 in which the threaded hole 96 is formed, be brought into contact. Therefore, if the bolt 97 into the threaded hole 96 screwed, the bolt must 97 within the recessed part 93 be rotated, resulting in coupling the fasteners 91 difficult.

Here are the sizes of the connection surfaces 24 . 34 equal. Then the terminal projections 26 the fluid control unit block 20 and the terminal projections 36 of the connection block 30 united to form beveled shapes having a decreasing thickness from the proximal end to the distal end. Also, every groove 25 the fluid control unit block 20 with the assigned groove 35 of the connection block 30 united to form a hole. In the present embodiment, a sealing element 42 , which is formed by an O-ring, between the connection surfaces 24 and 34 arranged. Another sealing element 42 like an O-ring, z. As a molded seal, can between the connection surfaces 24 and 34 to be ordered.

Then the other coupling element 40 arranged such that the connection projections 26 . 36 into the engagement recess 40b are used. Screws as fasteners 43 be in the mounting holes 40a of one of the coupling elements 40 used, and the fasteners 43 be in the grooves 25 . 35 used. The fasteners 43 then get into the mounting holes 40a of the other coupling element 40 screwed. Because the fasteners 43 Have thread, the coupling elements 40 brought closer to each other, so that the engagement recesses 40b the connection projections 26 . 36 press against each other. So are the connection surfaces 24 . 34 pressed against each other, so that the fluid control unit block 20 and the connection block 30 coupled together.

• (1) Die Anschlussvorsprünge 26, 36 und die Nuten 25, 35 sind in den Anschlussabschnitten 22, 32 des Fluidsteuergeräteblocks 20 und des Verbindungsblocks 30 ausgebildet. Die Anschlussvorsprünge 26, 36 des Fluidsteuergeräteblocks 20 und des Verbindungsblocks 30 stehen in Eingriff mit den Eingriffausnehmungen 40b der Kopplungselemente 40. Dann werden die Befestigungselemente 43 in die Befestigungslöcher 40a von außerhalb eines Kopplungselements 40 eingesetzt. Die Befestigungselemente 43 werden in die Befestigungslöcher 40a des anderen Kopplungselements 40 geschraubt, so dass der Fluidsteuergeräteblock 20 und der Verbindungsblock 30 miteinander gekoppelt sind. Das heißt, ein Einschrauben der Befestigungselemente 43 in die Befestigungslöcher 40a wird von außerhalb des Fluidsteuergeräteblocks 20 und des Verbindungsblocks 30 durchgeführt. Somit werden im Vergleich mit dem Stand der Technik, bei dem Bolzen eingeschraubt werden, damit sie vorstehen, um damit ein Koppeln durchzuführen, der Fluidsteuergeräteblock 20 und der Verbindungsblock 30 einfach miteinander gekoppelt. Im Ergebnis sind der Fluidsteuergeräteblock 20 und der Verbindungsblock 30 sicher miteinander gekoppelt, so dass ein Austritt von komprimierter Luft aufgrund eines Kopplungsfehlers verhindert wird.
• (2) Die Baugruppen der Luftdrucksteuergeräteeinheit 10 sind unter Verwendung der Koppelelemente 40 und der Befestigungselemente 43 miteinander gekoppelt. Daher kann z. B. wenn Fluidsteuergeräte wie z. B. ein Regler und ein Steuerventil miteinander unter Verwendung von Röhren und Verbindern verbunden werden, ein Dichtstoff in den Druckluftkreislauf während des Kopplungsvorgangs eindringen und einen Ausfall der Fluidsteuergeräte verursachen. Auch kann Luftaustritt aufgrund ungenügender Befestigung der Kopplung auftreten. Die vorliegende Erfindung verhindert diese Nachteile. Weiter, da keine Röhre zwischen den Baugruppen existiert, wird die Anzahl der Teile im Luftdruckkreislauf verringert, in denen sich die Flussdurchgangsfläche ändert. Dies verringert Druckverlust.
• (3) Die Baugruppen der Luftdrucksteuergeräteeinheit 10 sind miteinander unter Verwendung der Koppelelemente 40 und der Befestigungselemente 43 gekoppelt, wobei die Anschlussflächen 24, 34 miteinander in Kontakt gebracht werden. Daher kann im Vergleich dazu, wenn Rohre und Verbinder zwischen den Baugruppen existieren, die Größe des Druckluftkreislaufs verringert werden. Dies ermöglicht, die Druckluftsteuergeräteeinheit 10 in einem eingeschränkten Installationsraum zu installieren.
• (4) Beim Fluidsteuergeräteblock 20 mit dem Nadelventil 13 ist das Aufnahmeloch 27 im Anschlussblockhauptteil 21 ausgestaltet und das Nadelventil 13 kann entfernbar im Aufnahmeloch 27 aufgenommen werden. Dies erleichtert einen Austausch des Nadelventils 13.
• (5) Druckluft, die von der Luftversorgungsquelle P geliefert wird, wird in zwei Flüsse durch einen Verbindungsblock 30 aufgeteilt. Folglich ist es möglich, selbst wenn die Druckluftsteuergeräteeinheit 10 zwei Luftdruckkreisläufe besitzt, komprimierte Luft zu den jeweiligen Luftdruckkreisen von den einzelnen Luftversorgungsquellen P zu speisen. Verglichen mit einem Fall, in dem eine Luftversorgungsquelle P für jede der Luftdruckkreisläufe vorgesehen ist, wird der Installationsraum für die Luftdrucksteuergeräteeinheit 10 verringert.
• (6) Während Baugruppen miteinander unter Verwendung der Kupplungselemente 40 und der Befestigungselemente 43 gekoppelt werden können, können die Baugruppen einfach durch Außereingriffbringen der Befestigungselemente 43 von den Kopplungselementen 40 voneinander gelöst werden. Daher können die Baugruppen leicht von der Luftdrucksteuergeräteeinheit 10 abgebaut werden, was Wartung und Austausch erleichtert.
• (7) Wenn die Anschlussoberfläche 24 des Anschlussabschnitts 22 des Fluidsteuergeräteblocks 20 und die Anschlussoberfläche 34 des Anschlussabschnitts 32 des Verbindungsblocks 30 in Kontakt gebracht werden, werden die Nuten 25 des Fluidsteuergeräteblocks 20 und die Nuten 35 des Verbindungsblocks 30 vereint, um Durchgangslöcher auszubilden, welche die Befestigungselemente 43 aufnehmen können. Wenn die Befestigungselemente 43 in die durch die Nuten 25, 35 ausgestalteten Löcher von den Befestigungslöchern 40a eines der Befestigungselemente 43 eingesetzt werden, führen die Löcher der Nuten 25, 35 die Befestigungselemente 43 derart, dass die distalen Enden auf die Befestigungslöcher 40a des anderen Kopplungselements 40 ausgerichtet sind. Entsprechend erleichtern die Nuten 25, 35 in den Anschlussabschnitten 22, 32 das Verschrauben der Befestigungselemente 43.

The embodiment described above has the following advantages.

• (1) The terminal projections 26 . 36 and the grooves 25 . 35 are in the connection sections 22 . 32 the fluid control unit block 20 and the connection block 30 educated. The connection projections 26 . 36 the fluid control unit block 20 and the connection block 30 are engaged with the engagement recesses 40b the coupling elements 40 , Then the fasteners 43 in the mounting holes 40a from outside a coupling element 40 used. The fasteners 43 be in the mounting holes 40a of the other coupling element 40 screwed so that the fluid control unit block 20 and the connection block 30 coupled together. That is, a screwing the fasteners 43 in the mounting holes 40a is from outside the fluid control unit block 20 and the connection block 30 carried out. Thus, in comparison with the prior art in which bolts are screwed to protrude to perform coupling, the fluid control unit block 20 and the connection block 30 simply coupled with each other. As a result, the fluid control unit block 20 and the connection block 30 securely coupled together, so that leakage of compressed air due to a coupling error is prevented.
• (2) The assemblies of the air pressure control unit 10 are using the coupling elements 40 and the fasteners 43 coupled together. Therefore, z. B. if fluid control devices such. For example, a regulator and a control valve are connected to each other using tubes and connectors, a sealant penetrate into the compressed air circuit during the coupling process and cause failure of the fluid control devices. Also, air leakage may occur due to insufficient attachment of the coupling. The present invention prevents these disadvantages. Further, since there is no tube between the assemblies, the number of parts in the air pressure circuit in which the flow passage area changes is reduced. This reduces pressure loss.
• (3) The assemblies of the air pressure control unit 10 are interconnected using the coupling elements 40 and the fasteners 43 coupled, with the pads 24 . 34 be brought into contact with each other. Therefore, compared to when pipes and connectors exist between assemblies, the size of the compressed air circuit can be reduced. This allows the compressed air control unit 10 to install in a restricted installation room.
• (4) At the fluid control unit block 20 with the needle valve 13 is the recording hole 27 in the terminal block body 21 designed and the needle valve 13 can be removable in the receiving hole 27 be recorded. This facilitates replacement of the needle valve 13 ,
• (5) Compressed air supplied from the air supply source P is split into two flows through a connection block 30 divided up.

• (10) Die Kopplungselemente 40, die auf der Vorderseite der Luftdrucksteuergeräteeinheit 81 angeordnet sind, haben jeweils einen Anzeigebereich N. Daher ermöglicht es der Anzeigebereich N, die Flussrichtung der komprimierten Luft und den Name des Fluidsteuergeräts leicht sicht zu prüfen.

Therefore z. B. compared to when blocks 82 . 86 with each other with coupling elements 40 located above and below the air pressure control unit 81 are provided are coupled, a larger area for performing a variety of modes is created. Especially when the coupling elements above or below the air pressure control unit 81 Various operating modes require one hand to be confined in a narrow space between adjacent fluid control devices. Thus, the present embodiment assures a large space to facilitate various modes of operation. Also, since the fasteners 43 from the front of the air pressure control unit 81 can be screwed out or in, the screws can be performed without the need for a specially shaped tool.

• (10) The coupling elements 40 located on the front of the air pressure control unit 81 Therefore, the display area N makes it easy to inspect the flow direction of the compressed air and the name of the fluid control apparatus.

The present embodiment may be modified as follows.

As connecting blocks, connecting blocks having two terminal portions of different sizes (different shapes) can be used. As in 13 (a) to 13 (c) shown contains a connection block 60 a connection block body 61 , which is shaped like a rectangular parallelepiped or a cuboid. The connection block bulkhead 61 contains a communication passage 63 with openings on opposite sides of the connection block body 61 , The direction indicated by the arrow Y in which the communication passage 63 through the connection block body 61 extends as the axial direction of the connection block body 61 Are defined. In this case, the thickness is along the axial direction of the connection block 60 less than that of the connection block 30 of the first embodiment.

Two sides of the connection block body 51 in which the communication passage 63 has an opening, each have a connection section 62 projecting so as to form a rectangular plate-like shape. The outer end end face of the terminal section 62 forms a connection surface 64 and the communication passage 63 has an opening in the connection surface 64 , As in 13 (c) shown is the diameter of the communication passage 63 at one connection surface 64 different from the diameter at the other connection surface 64 ,

As in 13 (a) and 13 (b) shown have one of the terminal sections 62 and the other terminal section 62 different sizes (shapes). Also has each connection section 62 a pair of or two grooves 65 which are configured along two opposite sides. The grooves 65 are on both sides of the opening of the fluid passage 63 arranged. The grooves 65 that in the connection sections 62 are designed to extend in the same direction. Each connection section 62 also has a pair of or two terminal projections) 66 which are arranged on opposite sides and project in the direction in which the grooves 65 extend. The connection projections 66 the two connection sections 62 extend in the same direction. One of the connection sections 62 and the other terminal section 62 have different sizes or different lengths in the direction in which the grooves 65 extend, and different lengths in a direction which is perpendicular to the direction in which the grooves 65 extend. The connection tab 66 standing on one of the connecting sections 62 is configured, and the connection projection 66 on the other connection section 62 is configured from the respective connection section 62 from different lengths in the projection direction.

For example, the filter block 204 with one of the connection sections 62 of the connection block 60 coupled. Next is the other connection section 62 with the smaller size with an air-pressure operated device (not shown) or a fluid control unit block having a connection portion with a smaller size than the terminal portion 22 of the filter block 204 has connected. Therefore, by using the connection block 60 at the air pressure control unit 10 Fluid control device blocks 20 different size or a fluid control unit block and a pressure-actuated device of different sizes with each other via the connection block 60 be coupled. Therefore, the size of the air pressure control unit 10 by coupling fluid control unit blocks 20 be reduced with reduced sizes. This allows the air pressure control unit 10 to install in a wider scope of installation rooms.

At the connection block 60 who in 13 is shown, the terminal projections 66 coming from the connecting sections 62 stand out, shaped so that they extend forwards and backwards.

As in 14 shown, the air pressure control unit 80 contain two fluid circuits arranged in parallel. The air pressure control unit 80 contains two coupled connection blocks 30 , A fluid control unit block 20 with a pressure gauge 15 acting as a fluid control device (hereinafter referred to as a pressure indicating block 205 is designated) is with each connection block 30 coupled and two valve blocks 202 are with every pressure gauge block 205 coupled. A separating plate or a separating plate 71 is between the connection sections 32 the connection blocks 30 arranged. Compressed air becomes one of the two connection blocks 30 and one fluid (fluid) becomes the other connection block 30 cleverly. The partition plate 71 between the connection blocks 30 Prevents different fluids in different fluid circuits mix with each other. This allows the air pressure control unit 80 has different fluid circuits. Alternatively, an air pressure control unit may be coupled by coupling three or more connection blocks 30 and coupling other assemblies to each connection block 30 be configured so that the unit has three or more fluid circuits.

At the connection block 50 of the second embodiment, the direction in which one of the terminal portions 52 protrudes, and the direction in which the other terminal section 52 protrudes, intersect, so that the angle, which is defined by the projection direction, on a other angles than 90 °, z. B. 80 ° or 45 °, can be adjusted.

A fluid control unit block, which is an assembly of the fluid control unit, includes a check valve unit that operates as a fluid control unit. Especially, as in 16 shown contains a fluid control unit block 82 According to the third embodiment, a check valve unit C in the terminal block main body 83 , Three sides of the terminal block body 83 in which the fluid passage 84 has an opening, each have a connection section 85 which protrudes so as to form a rectangular plate-like shape.

At the terminal block body 83 is the direction in which the fluid passage 84 through the terminal block bulkhead 83 extends as the axial direction of the terminal block body 83 Are defined. At the fluid control unit block 82 of the present embodiment has the fluid passage 84 an opening in a direction perpendicular to the axial direction. That is, the fluid passage 84 extends such that it forms a T-shape.

As in 15 shown is every connection section 85 of the terminal block body part 83 adjacent to the back surface 83a and the front surface 83b and is in one side, which is the back surface 83a and the front surface 83b crosses (perpendicular to it is). Also, as in the first embodiment, has the connection portion 85 a connection surface 85a , Grooves 85b and a pair of or two terminal sections (n) 85c , Further, a display area N of an arrow is the flow direction of compressed air in the fluid control unit block 82 indicating, on the front surface 83b of the terminal block body part 83 intended.

As in 16 shown is part of the fluid passage 84 extending along the axial direction of the terminal block body 83 extends as a round hole with a larger diameter than the rest of the fluid passage 84 educated. A valve chamber 79 is defined in the enlarged diameter part. The valve chamber 79 is configured as a circular hole extending along the axial direction of the terminal block body 83 extends. A valve seat 78 is at an inner, the valve chamber 79 forming surface of the terminal block body 83 educated. Especially the valve seat is located 78 at the periphery of the opening of the fluid passage 84 leading to the valve chamber 79 is directed.

The check valve unit C is in the valve chamber 79 added. The test valve unit C includes a valve body 73 , a cylindrical valve guide 74 , a cap and a constraint element or pressure element 76 , The valve guide 74 Integrally holds the valve body 73 and is in the valve chamber 79 added. The cap 75 is in the fluid passage 84 installed to the position of the valve guide 74 in the valve chamber 79 set. The compulsory element 76 pushes or forces the valve guide 74 in the direction of the valve seat 78 , A cylindrical guide section 74a is on the outer circumference of the valve guide 74 designed. The guide section 74a slides on the inner circumferential surface of the valve chamber 79 , causing the valve guide 74 or the valve body 73 leads to move along the axial direction of the terminal block body 83 to move. Next has the valve guide 74 a communication hole (not shown) for connecting the valve chamber 79 with the interior of the valve guide 74 ,

The compulsory element 76 is formed by a spiral or coil spring and is within the guide section 74a the valve guide 74 arranged. An end to the coercive element 76 touches the valve guide 74 and the other end contacts the inner end face of the cap 75 , When no fluid pressure is greater than or equal to a predetermined value on the valve body 73 acts, provides the coercive element 76 for the valve body 73 in contact with the valve seat 78 is held.

As in 17 shown is an engagement groove 75a formed along the entire outer peripheral surface of the cap 75 extends. The connection block bulkhead 83 also has vertically extending insert holes 83c at the opening of the fluid passage 84 with respect to the valve chamber 79 are arranged. The insert holes 83c are on both sides of the fluid passage 84 arranged. With the in the fluid passage 84 taken cap 75 connects the engagement groove 75a the cap 75 both sides of the radial direction with the insertion hole 83c of the terminal block body part 83 , When a retaining pin shaped into a U 70 in the insertion holes 83c of the terminal block body part 83 is used, the retaining pin 70 into the engagement groove 75a the cap 75 and the insertion holes 83c of the terminal block body part 83 used, so the retention pin 70 the cap 75 in the fluid passage 84 restrains. That way, the cap will 75 in the fluid passage 84 Installed.

With the in the fluid passage 84 restrained cap 75 is an O-ring 77 between the outer peripheral surface of the cap 75 and the inner peripheral surface of the fluid passage 84 arranged to fluid leakage between the outer peripheral surface of the cap 75 and the inner peripheral surface of the fluid passage 84 to prevent.

At the fluid control unit block 82 of the present embodiment, the valve body 73 when compressed air into one (the left, as in 16 considered) of the two openings of the fluid passage 84 that is along the axial direction is arranged, is fed, in contact with the valve seat 78 held until a fluid pressure of a certain value or greater on the valve body 73 acts. So the compressed air does not get to the other end (the right end, as in 16 considered) of the fluid passage 84 delivered. Instead, the compressed air becomes the fluid passage 84 supplied perpendicular to the axial direction of the terminal block main body 83 extends. When a fluid pressure of the predetermined value on the valve body 73 acts, the valve guide 74 so moved that the valve body 73 from the valve seat 78 is disconnected. This allows the compressed air into the valve chamber 79 flows, allowing the compressed air from the communication hole of the valve guide 74 in the valve guide 74 flows. The compressed air is from an opening of the fluid passage 84 delivered to the other opening.

At the fluid control unit block 82 is when compressed air from one of the two openings (the right, as in 16 considered) of the fluid passage 84 extending along the axial direction of the axial direction of the terminal block body 83 extends, flows back, the valve guide 74 , which receives the pressure of fluid reflux, in the direction of the valve seat 78 moves, leaving the valve body 73 the valve seat 78 touched. This prevents compressed air from flowing to the left opening of the fluid passage 84 flowing back.

As in 18 shown has the fluid control unit block 82 with the test valve unit C, which in 15 to 17 shown is a pressure gauge 72 for indicating the fluid pressure in the fluid passage 84 ,

Means for coupling the fluid control unit blocks 20 . 82 with the connection blocks 30 . 50 . 60 . 86 can through a pair of connection tabs 26 . 36 . 56 . 66 . 85c . 89c , Fasteners 43 and two coupling elements 40 be designed.
