Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a solenoid valve manifold configured by connecting a plurality of manifold blocks each having a solenoid valve mounted thereon.
[0002]
[Prior art]
In order to improve the installation and maintainability of this type of solenoid valve manifold, a wiring-saving type that collectively supplies power from one side is becoming mainstream. In recent years, there has been an increasing need for highly integrated manifold blocks. If power is supplied to the manifold only from one side, the number of electrical connection points may be insufficient, and it is necessary to supply power to the solenoid valve manifold from both sides. If there is a restriction on the installation location of the solenoid valve manifold, a situation may occur in which power is supplied only from the side opposite to the side to which power is normally supplied. Under these circumstances, an electromagnetic valve manifold capable of supplying power from both sides of the electromagnetic valve manifold has been conventionally proposed (for example, see Patent Document 1).
[0003]
As shown in FIG. 10, in the solenoid valve manifold 51, a plurality of connection terminals of the same number on the left and right provided in a manifold block 52 which is continuously provided are electrically connected while being shifted in the arrangement direction. Among the connection terminal rows, the respective connection terminals to which the left and right connection terminals are not electrically connected are connected to the solenoid valve 53 mounted on the manifold block. With such a wiring structure, by changing the left and right positions of the wiring saving block 54, it is possible to output a drive command signal from the manifold block 52 at either of the left and right continuous ends. It is possible to select which of the left and right should output the drive command signal.
[0004]
Prior art document information related to the invention of this application includes the following.

[Problems to be solved by the invention]
If the manifold block 52 is a double solenoid type, there are two drive command signal arrays (hereinafter simply referred to as signal arrays) per manifold block 52. Therefore, the signal arrangement focusing only on the double solenoid type is 1a, 1b when power is supplied from the left side, and 1b, 1a when power is supplied from the right side. In other words, when power is supplied from the left side, the signal array is arranged as "abbaab ...", while when supplied from the right side, it is arranged as "baaba ...". Become. In short, the order of signal arrangement differs depending on the direction of power supply. For this reason, when a user composes a control program, it causes confusion. This may cause a malfunction in use.
[0007]
The present invention has been made by focusing on the problems existing in such conventional techniques. It is an object of the present invention to provide an electromagnetic valve manifold that can avoid a mistake in a control program rewritten when changing a manifold power supply direction and a malfunction due to the mistake.

[0012]

Each of the blocks 12, 13, 14, 15L is continuously provided along the longitudinal direction of the DIN rail 11.
[0013]
One fluid pressure device (not shown) is connected to each manifold block 14, and supply of pressure fluid to each fluid pressure device via output ports 17, 18 provided on the side surface of each manifold block 14. Exhaust is performed. In each of the manifold blocks 14, one of the two output ports 17 and 18 is alternately switched between an air supply and an exhaust for the two output ports 17 and 18 by an electric operation, so that the fluid pressure device operates. .
[0014]
Switching between the output ports 17 and 18 is performed by first and second solenoid valve mechanisms 19a and 19b mounted on each manifold block 14, respectively. Each first solenoid valve mechanism 19a has one first solenoid valve 1a to 7a, and each second solenoid valve mechanism 19b has one second solenoid valve 1b to 7b. That is, since each manifold block 14 has two first and second solenoid valves 1a to 7a and 1b to 7b in total, the manifold block 14 is a double solenoid type. Then, power is supplied to each of the first and second solenoid valve mechanisms 19a and 19b of each manifold block 14 via a multi-pole cable (not shown) connected to the multi-pole connector 20 provided in the wiring saving block 15L. .
[0015]

A hole 25 is formed. A wiring circuit 26 connected to the first and second solenoid valve mechanisms 19a and 19b is accommodated in the accommodation hole 25. On one side edge of the wiring circuit 26, the left specific connection terminals A1, A2, the left connection terminals A3 to A14, and the common terminal ACOM, all of which are female, are provided on the same arrangement line. On the other side edge of the wiring circuit 26, right connection terminals B1 to B12, right specific connection terminals B13 and B14, and a common terminal BCOM, all of which are male, are provided.
[0016]
As shown in FIG. 5, the left connection terminals A3 to A14 and the right connection terminals B1 to B12 are connected to the first and second solenoid valves 1a to 7a and 1b provided in one manifold block 14. The corresponding connections are shifted in the arrangement direction by the number value “2” of 7b. The two specific connection terminals A1 and A2 provided on the array of the left connection terminals A3 to A14 are not one-to-one connected to the right connection terminals B1 to B12. Therefore, in the present embodiment, the left specific connection terminals A1 and A2 connected to the respective solenoid valves 1a to 7a and 1b to 7b are connected to the left connection terminal row A described in the claims. The left specific connection terminal that is not connected while being shifted in the arrangement direction. One specific connection terminal A1 is connected to the first electromagnetic valves 1a to 7a, and the other specific connection terminal A2 is connected to the second electromagnetic valves 1b to 7b.

Each of the solenoid valves 1a to 7a and 1b to 7b is connected to a common terminal CCOM via the left and right common terminals ACOM and BCOM.
[0018]
The left specific connection terminals A1 and A2 connected to the respective solenoid valves 1a to 7a and 1b to 7b and the right specific connection terminals B14 and B13 are connected via a circuit pattern formed in the wiring circuit 26. It has the following connection relationship. That is, the first specific connection terminal A1 counted from one end side of the left connection terminal row A (upper side in FIG. 5), and the specific connection terminal A1 counted from the other end side (lower side in FIG. 5) of the right connection terminal row B. Is connected to the first specific connection terminal B14. A second specific connection terminal A2 counted from one end of the left connection terminal row A and a second specific connection terminal B13 counted from the other end of the right connection terminal row B are connected. In short, the left specific connection terminals A1, A2 and the right specific connection terminals B13, B14 are the same specific connection terminals A1, B14 (A2) counted from the ends of the connection terminal rows A, B. , B13) are connected to each other.
[0019]
As shown in FIGS. 5 and 6, in the wiring-saving blocks 15L and 15R, power supply terminals C1 to C14 for outputting a drive command signal are provided, and the power supply terminals C1 to C14 are connected to the multi-pole connector. 20 terminals. The power supply terminals C1 to C14 can be connected to the connection terminals A3 to A14 and B1 to B12 of the manifold block 14 at any of the left and right continuous ends. The reduced wiring block 15L is continuously used for the manifold block 14 located at the left end of the continuous group. On the other hand, a wire-saving block 15R is continuously provided on the manifold block 14 located at the right end. In addition, the common terminal CCOM connected to the common terminal ACOM on the left side of each manifold block 14 is provided in the wiring saving block 15L. The common wiring terminal CCOM connected to the common terminal BCOM on the right side of each manifold block 14 is provided in the wiring saving block 15R.
[0020]
Note that the left connection terminal row A excludes the common terminal ACOM, and refers to an arrangement of a terminal group including left specific connection terminals A1 and A2 and left connection terminals A3 to A14. . Further, the right connection terminal row B, excluding the common terminal BCOM, refers to an arrangement of a terminal group including right connection terminals B1 to B12 and right specific connection terminals B13, B14. . Further, the power supply terminal row C is one except for the common terminal CCOM, and refers to an array of power supply terminals C1 to C14.
[0021]
As shown in FIG. 6, when the reduced wiring block 15L is connected to the manifold block 14 at the left end, the specific connection terminals A1 and A2 are connected to the power supply terminals C1 and C2. , C3 to C14 are connected to the left connection terminals A3 to A14. In this connection state, it is assumed that a drive command signal is output from the n-th power supply terminal Cn of the power supply terminal row C. Here, in the case where the array numbers of the manifold blocks 14 counted from the order close to the wiring saving block 15L are 1, 2,..., 7, the array number is “(n + 1) / 2” when n is an odd number. The first solenoid valve mechanism 19a provided in the manifold block 14 is driven. For example, when the drive command signal is output from the power supply terminal C3 located third from the one end side (upper side in FIG. 6) of the power supply terminal row C, the first solenoid valve of the manifold block 14 having the array number 2 The mechanism 19a is driven.
[0022]
When n is an even number, the second solenoid valve mechanism 19b provided in the manifold block 14 having the array number “n / 2” is driven. For example, when the drive command signal is output from the fourth power supply terminal C4 counted from one end of the power supply terminal row C, the second solenoid valve mechanism 19b of the manifold block 14 having the second array number is driven. .
[0023]
Thus, when n is an odd number, the driven first electromagnetic valve mechanism 19a (first electromagnetic valves 1a to 7a) is energized, and when it is an even number, the driven second electromagnetic valve mechanism 19b ( The second solenoid valves 1b to 7b) are energized. Here, for convenience of description, reference numerals of the first and second solenoid valves 1a to 7a and 1b to 7b are substituted for the signal arrangement of the drive command signals output from the power supply terminals C1 to C14. Then, the signal arrangement is set alternately with respect to the first solenoid valves 1a to 7a and the second solenoid valves 1b to 7b. 1a, 1b, 2a, 2b ... ". That is, the signal arrangement is set in the order of a, b, a, b,.
[0024]
Next, when connecting the reduced wiring block 15R to the manifold block 14 at the right end, the right connection terminals B1 to B12 are connected to the power supply terminals C1 to C12, and the power supply terminals C13 and C14 are connected to the power supply terminals C13 and C14. The right specific connection terminals B13 and B14 are connected. In this state, assuming that a drive command signal is output from the nth power supply terminal Cn of the power supply terminal row C, when n is an odd number, the first number provided in the manifold block 14 having the array number of “(n + 1) / 2” is provided. And the second solenoid valve mechanisms 19a and 19b are driven. When n is an even number, the first and second solenoid valve mechanisms 19a and 19b provided in the manifold block 14 having the array number "n / 2" are driven. Moreover, the signal arrangement of the drive command signals is “1a, 1b, 2a, 2b,. That is, the signal arrangement is set in the order of “a, b, a, b.
[0025]
From the above, when all the manifold blocks 14 are of the double solenoid type only, the signal arrangement of the drive command signals is different between the case where the wiring saving blocks 15L and 15R are arranged on the left side and the case where they are arranged on the right side. Are not different.
[0026]
It is assumed that one of the double solenoid type manifold blocks 14 has been replaced with a single solenoid type manifold block 14 including only the first solenoid valves 1a to 7a due to a change in the specification of the solenoid valve manifold 10 or the like. Here, it is assumed that the manifold block 14 having the array number 2 is replaced with a single solenoid as shown in FIG. In this case, if the wiring-saving block 15L is connected to the manifold block 14 at the left end, the signal sequence of the drive command signal is “1a, 1b” in order from one end of the power supply terminal row C. , 2a, 3a, 3b, 4a... ”, And“ a ”is set first in each series.
[0027]
On the other hand, even when the wiring-saving block 15R is arranged on the right side, the signal arrangement of the drive command signal is “1a, 1b, 2a, 3a, 3b, 4a ... ". That is, the signal arrangement is set with “a” first in each series. As described above, even if the single solenoid type and the double solenoid type are mixed among the plurality of manifold blocks 14, the signal arrangement always starts from "a" and does not become irregular.
[0028]
Therefore, according to the present embodiment, the following effects can be obtained.
(1) The left specific connection terminals A1 and A2 and the right specific connection terminals B13 and B14 are connected to each other at the same position counted from the ends of the connection terminal rows A and B. I have. With this configuration, the reduced wiring block 15L is connected to the manifold block 14 at the left continuous end, and the reduced wiring block 15R is connected to the manifold block 14 at the right continuous end. In each case, the order of the signal arrangement of the drive command signals becomes the same. Therefore, even if the power supply direction of the solenoid valve manifold 10 is changed, it is easy to understand the signal arrangement of the drive command signal. Therefore, mistakes in rewriting the program for controlling the solenoid valve manifold 10 are reduced, and the malfunction of the solenoid valve manifold 10 due to the mistake can be prevented.
[0029]
(2) Even if the manifold block 14 having a double solenoid and the manifold block 14 having a single solenoid are connected in series, the signal arrangement of the drive command signal is set to "a" first in each connection. Therefore, it is possible to prevent the signal arrangement from becoming irregular.
[0030]
(2nd Embodiment)
The second embodiment will be described focusing on the differences from the above embodiment.
As shown in FIGS. 8 and 9, the first specific connection terminal A1 counted from one end side of the left connection terminal row A (upper side in FIG. 8) and the other end side of the right connection terminal row B ( The specific connection terminal B13, which is the second counting from the lower side in FIG. 8, is connected. Also, the second specific connection terminal A2 counted from one end of the left connection terminal row A and the first specific connection terminal B14 counted from the other end of the right connection terminal row B are connected. I have.
[0031]

The left power supply terminals C1 to C14 and the right power supply terminals D1 to D14 are connected via the above-described circuit pattern of the wiring board (not shown). The connection relationship between these power supply terminals C1 to C14 and D1 to D14 is as follows.
[0032]
That is, the odd-numbered power supply terminals C1, C3,...

Are connected in the order of their arrangement. The even-numbered power supply terminals C2, C4... Counted from one end of the left power supply terminal row C and the odd-numbered power supply terminals D1, D3. Are connected in the order of their arrangement. The wiring-saving block 15R is provided with common terminals CCOM and DCOM connected to the common terminals ACOM and BCOM of the manifold block 14.
[0033]
As shown in FIG. 9, when the reduced wiring block 15R is connected to the manifold block 14 at the right connecting end, the left power supply terminals C1 to C12 are connected to the right connection terminals B1 to B1. While being connected to B12, the remaining power supply terminals C13 and C14 are connected to the right specific connection terminals B13 and B14. In this connection state, the signal arrangement of the drive command signal is alternately applied to the first solenoid valves 1a to 7a and the second solenoid valves 1b to 7b in order from the power supply terminals C14 to C1 on the other end side of the power supply terminal row C. Is set to not be irregular.
[0034]
On the other hand, although not shown, when the reduced wiring block 15L is connected to the manifold block 14 at the left end, the right power supply terminals D3 to D14 are connected to the left connection terminals A3 to A14. While being connected, the remaining power supply terminals C1 and C2 are connected to the left specific connection terminals A1 and A2. Even in this connection state, the signal arrangement of the drive command signals output to the first solenoid valves 1a to 7a and the second solenoid valves 1b to 7b does not become irregular.
[0035]
Therefore, also in the second embodiment, when all the manifold blocks 14 are of the double solenoid type only, the drive command signal is different between the case where the wiring saving block 15L is arranged on the left side and the case where the wiring saving block 15L is arranged on the right side. Can be the same.
[0036]
