[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a manifold cylinder in which a pair of cylinders constitutes one drive unit.

[0002]

[Prior art]

 When producing multiple types of products on the same production line, it is necessary to replace the cylinder-based manufacturing equipment on the production line each time the product type is switched. For example, when positioning and fixing an automobile body by a positioning jig that uses a cylinder on an automobile production line, prepare a positioning jig for each type and prepare the manufacturing equipment according to the type of the car that is sent. It is necessary to switch to the position of use.

[0003]

[Problems to be solved by the device]

 However, recently, the production of a large number of small varieties has been required to produce a large amount of medium varieties or a small amount of large varieties, and frequent replacement of manufacturing equipment is an obstacle to production efficiency.

An object of the present invention is to provide a compact manifold cylinder in which a manufacturing device using a cylinder can be easily selected and used even when a product type sent to a production line is different each time. It is a thing.

Each polymerization mounting holes 1a which polymerize 1-one, cylinder 6A ₁ Between _{2a, 6A 2, 6A 3,} 6 A 4, 7A 1, 7A 2, 7A 3, 7A 4, 6B 1, 6B 2, 6B 3 , 6B ₄ , 7B ₁ , 7B ₂ , 7B ₃ , 7B ₄ are fitted and erected, and fixed by tightening with a nut 8. From the top, the arrangement of the first-stage cylinders 6A _{1 to} 6A _{4 and} the arrangement of the third-stage cylinders 6B _{1 to} 6B ₄ are superposed when viewed in the vertical direction, and the second-stage cylinders 7A _{1 to} 7A are superposed. ₄ in the sequence and the fourth stage of the sequence of the cylinder 7B ₁ ~7B ₄ are polymerized. Then, and first and third stage cylinder _{6A 1 ~6A 4, 6B 1 ~6B} 4 and the second, fourth stage of the cylinder _{7A 1 ~7A 4, 7B 1 ~7B} 4 being offset half a pitch in the lateral direction , As a whole, each pair of cylinders is arranged in a staggered arrangement. Therefore, a total of 16 cylinders 6A _{1 to} 6A ₄ , 7A _{1 to} 7A ₄ , 6B _{1 to} 6B ₄ , 7B ₁ to 7B ₄ are compactly arranged on the square support plates 1 and 2.

Each cylinder 6A₁~ 6A_Four, 7A₁~ 7A_Four, 6B₁~ 6B_Four, 7B₁~ 7B _Four Have the same configuration. A rod cover 10 and a head cover 11 are fitted and fixed at both ends of the cylinder tube 9, the rod cover 10 is fitted in the mounting hole 1a of the front support plate 1, and the head cover 11 is mounted in the mounting hole of the rear support plate 2. 2a is fitted. Both covers 10 and 11 cannot be pulled out from the front side to the rear side with respect to the respective support plates 1 and 2, and by tightening the nut 8 on the head cover 11, the cylinder 6A.₁~ 6A_Four, 7A₁~ 7A_Four, 6 B₁~ 6B_Four, 7B₁~ 7B_FourIs clamped and fixed on both support plates 1 and 2.

A piston 12 is slidably accommodated in the cylinder tube 9, and a piston rod 12 a thereof is slidably protruded from a rod cover 10, so that the inside of the cylinder tube 9 is actuated by a piston 12 in a working chamber 9 a. , 9b. The rod cover 10 is provided with a pair of ports 10a, 10b at vertically symmetrical positions, and each port 10a, 10b communicates with one working chamber 9a via the flow paths 10c, 10d in the rod cover 10. There is.

A straight pipe joint 13 is screwed to the upper port 10a of each of the first-stage cylinders 6A _{1 to} 6A ₄ , and a supply / exhaust tube 14 is connected to the pipe joint 13. a first stage of the lower port 10b of the cylinder 6A ₁ ~6A ₄ and Siri Sunda 6B ₁ ~6B ₄ of the upper port 10a of the third stage are communicated via the auxiliary tube 15. Also, the third stage of the lower port 10b of the cylinder 6B ₁ ~6B ₄ are then the blank plug. That is, working chamber 9a of the cylinder 6B ₁ ~6B ₄ of the third-stage flow path of the third stage of the flow path 10c of Cylinders 6B ₁ ~6B _4, the auxiliary tube 15, the first stage cylinder 6A ₁ ~ 6A ₄ 10d, the working chamber 9a, the flow passage 10c, and the pipe joint 13 so as to communicate with the supply / exhaust tube 14.

On the other hand, the head cover 11 is provided with one port 11a communicating with the working chamber 9b, and a T-shaped pipe joint 16 is screwed to the ports 11a of the third stage cylinders 6B _{1 to} 6B _4. At the same time, a supply / exhaust tube 17 is connected to the pipe joint 16. Further, the first stage port 11a of the cylinder 6A ₁ ~6A ₄ has KanTsugi hand 18 of the elbow is screwed, between the pipe joint 18, 16 is connected by an auxiliary pipe 19. That is, working chamber 9b and the third stage of shea cylinder 6B ₁ working chamber 9b of ～6B ₄ of the first stage cylinder 6A ₁ ~6A ₄ is communicated with the supply and exhaust tube 17 together. Therefore, intake and exhaust solenoid valves (not shown) connected to the tube 14, 17 the piston rod 12a and the third stage cylinder 6B ₁ ~6B ₄ cylinder 6A ₁ ~6A ₄ of the first stage by the switching control of (total eight in) Piston rod 12a moves in the same direction. That is, when compressed air is supplied from the supply / exhaust tube 17 side and compressed air is exhausted from the supply / exhaust tube 14 side, the piston rod 12a of the cylinder pair moves in association with the protruding position as shown in FIG. If compressed air is supplied from the air supply / exhaust tube 14 side and compressed air is exhausted from the air supply / exhaust tube 17 side, the piston rod 12a of the anti-cylinder returns in conjunction with the retracted position as shown in FIG.

Therefore, if a device such as a manufacturing jig is installed between the piston rods 12a of the cylinders 6A _{i to} 6B _i (i = 1 to 4), the device does not rotate and is not in use position. The cylinders 6A _i and 6B _i are arranged so as to be switched to the use position, and each of them constitutes one drive unit.

A pair of piston position detectors 20 are attached to the cylinder tube 9 of the first-stage cylinder 6A _{i with} a band 21, and an annular permanent magnet 22 attached to the piston 12 comes to a predetermined position. And the piston position detector 20 detects the piston position by magnetic sensing.

The second-stage cylinders 7A _{1 to} 7A ₄ and the fourth-stage cylinders 7B _{1 to} 7B ₄ are paired similarly to the pairing relationship between the first-stage cylinder 6A _i and the third-stage cylinder 6B _i . The relationship is configured such that the piston rod 12a of the second stage cylinder 7A _j (j = 1 to 4) and the piston rod 12a of the fourth stage cylinder 7B _j are connected to the supply / exhaust tubes 23, 24. The solenoid valves (8 in total) (not shown) are opened and closed to move in the same direction. Also, a pair of piston position detectors 25 are attached to the fourth stage cylinder 7A _j .

A pair of notches 10e ₁ and 10e ₂ are formed on the outer peripheral surface of the rod cover 10 of each of the cylinders 6A _{1 to} 7B ₄ , and the first stage cylinder 6A _i and the third stage cylinder 6B are formed. A gap formed by notches 10e ₂ and 10e ₁ between adjacent cylinders of an auxiliary tube 15 that communicates with _i and an auxiliary tube 26 that communicates with the second-stage cylinder 7A _j and the fourth-stage cylinder 7B _j Is installed in.

Therefore, the compact arrangement of the 16 cylinders 6A _{1 to} 7B ₄ is not hindered by the auxiliary tubes 15 and 26, and the pair of cylinders 6A _i , 6B _i and 7A _j , 7B _j are bundled in the most compact manner. To be

The compact cylinder pair 6A thus assembled_i, 6B_iAnd 7A_j, 7B _j The choice of use can be easily made by controlling the opening and closing of the solenoid valve that constitutes the compressed air supply system together with the supply / exhaust tubes 14, 17, 23, 24. Therefore, it is possible to easily deal with the change of the product type as many as the number of cylinders (eight in this embodiment).

A semi-circular through recess 1b is formed continuously in the mounting hole 1a of the front support plate 1 for mounting the first-stage cylinder 6A _i and the fourth-stage cylinder 7B _j. When the cylinders 6A _i and 7B _j are inserted and mounted in the mounting holes 1a and 2a of the support plates 1 and 2, the piston position detectors 20 and 25 are passed through the recessed portion 1b.

Of course, the present invention is not limited to the above-described embodiment, for example, the strokes of the pair of cylinders may be different from those of the other pair of cylinders, or one of the pair of cylinders may have a smaller diameter than the other. Alternatively, an embodiment in which the working fluid supply / exhaust for interlocking both piston rods of the cylinder-to-cylinder are all branched and supplied outside the both cylinders is also possible.
