  The above-described conventional cable protection and guide device is, for example, a second member in which one end in the longitudinal direction is fixed to the first member while the other end in the longitudinal direction moves relative to the first member. It is fixed and it is comprised so that the middle part of the longitudinal direction may curve-operate with relative movement of the 1st member and the 2nd member. And, in this case, when the direction in which the first member and the second member move relative to each other is only along one direction, the male and female fit of the concave groove and the convex stripe in the cylindrical wall surrounding the accommodation space There is a low possibility that they will break.

  However, when the first member and the second member move relative to each other with a three-dimensional movement, a twist is generated in an intermediate portion in the longitudinal direction of the cylindrical wall portion, so that the cylindrical shape is caused by the twist. There is a possibility that the males and females of the concave groove and the convex line in the wall portion may be disengaged, and the cables may protrude from the inside to the outside of the accommodation space.

  The present invention has been made in view of such circumstances, and an object thereof is to twist a midway portion in a longitudinal direction in a cylindrical wall portion surrounding a housing space in which cables are accommodated in a state of being elongated. It is an object of the present invention to provide a cable protection and guide device and its mounting structure capable of reducing the possibility that cables may pop out from the inside to the outside of the accommodation space even when it occurs.

Hereinafter, the means for solving the above-mentioned subject and its operation effect are described.
A cable protection and guide device for solving the above-mentioned problems is provided at a first end of the sheet in the width direction of a sheet having flexibility and extending in one direction by bending a sheet along a longitudinal direction. A storage space capable of storing elongated cables along the longitudinal direction of the sheet by locking the first locking portion and the second locking portion provided at the second end. While the first portion in the longitudinal direction of the cylindrical wall portion surrounding the accommodation space is fixed to the first member, and the second portion separated from the first portion in the longitudinal direction is the first member Is fixed to a second member that moves relative to the second member, and a portion of the wall portion positioned between the first portion and the second portion is curved along with the relative movement of the first member and the second member. A cable protection and guidance device configured to displace while In the wall portion, a portion of the wall portion positioned between the first portion and the second portion in a state where the first locking portion and the second locking portion are locked is curved. A lock release restricting member is mounted which restricts release of the lock state between the first lock portion and the second lock portion when being displaced.

  According to this configuration, when the first member and the second member move relative to each other with a three-dimensional movement, the tubular wall portion in the longitudinal direction between the first portion and the second portion There is a possibility that the locked state between the first locking portion and the second locking portion may be released because the portion is twisted, but such a risk may be caused by the locking release regulating member attached to the wall portion. Reduced.

  In the above-described cable protection and guide device, the lock release restriction member is a fixing portion fixed to the first member or the second member, and the first portion or the second portion of the wall portion. It is preferable to have an engaging portion that can hold the locked state of the first locking portion and the second locking portion.

It is formed to span the whole of

Next, the operation of the cable protection and guide device 11 configured as described above will be described.
Now, as shown in FIG. 4, in the cable protection and guide device 11, the sheet 21 is bent at the bending portion 22, and the first locking portion 33 and the second locking portion 34 are locked. A cylindrical wall portion 40 capable of accommodating the cables 27 in the accommodation space 28 is formed. In such a case, a jig 43 as shown in FIG. 4 is used to improve the workability. That is, the jig 43 includes a knob 45 which the user can pinch with the finger tip 44 of the hand, and a first locking portion 33 and a second linking wall 26 of the first connecting wall 25 of the sheet 21. An engagement portion 46 is formed to be engageable with the first engaged portion 41 and the second engaged portion 42 so as to be capable of holding a locked state with the second locking portion 34.

  The knob portion 45 of the jig 43 has a rectangular plate shape whose size is, for example, about the same as that of the finger tip 44 of a human hand, and a hole 47 is formed in a substantially central portion thereof. On the other hand, the engaging portion 46 has a substantially U-shaped cross-sectional shape having a first engaging groove 48 and a second engaging groove 49 having a pair of angular grooves or dovetails on the inner surface side and a planar shape It is a substantially rectangular plate member, and the pick part 45 is erected from the outer surface on the opposite side to the inner surface in which the 1st engagement groove 48 and the 2nd engagement groove 49 were provided. The first engagement groove 48 in the engagement portion 46 is engageable with the first engaged portion 41 in the first connection wall 25, and the second engagement groove 49 in the engagement portion 46 is a second connection wall It is engageable with the second engaged portion 42 in the portion 26.

  When forming the cylindrical wall portion 40 using such a jig 43, first, as shown in FIG. 4, one end in the longitudinal direction Y of the wall portion 40 (left end portion in FIG. 4) The first locking portion 33 of the first connection wall 25 and the second locking portion 34 of the second connection wall 26 are locked. At this stage, the jig 43 is not used yet, and the user uses the finger tip 44 of the hand to use the finger 36 of the wall portion 40 only at one end of the wall portion 40 in the longitudinal direction Y, Male and female are fitted in the concave groove 38 on the locking portion 34 side. That is, the convex bar 36 on the side of the first locking portion 33 is inserted into the recessed groove 38 on the side of the second locking portion 34 while elastically deforming the second plate portion 37, and the first locking portion 33 and the first locking portion 33 2 Lock the locking portion 34.

  Then, next, the user picks the picker 45 of the jig 43 with the finger tip 44 of the hand, and the jig 43 is used from one end to the other end in the longitudinal direction Y of the cylindrical wall 40 (right end in FIG. Slide toward the part). Then, the first locking portion 33 and the second locking portion 34, which had been locked only at one end in the longitudinal direction Y until then, are recessed by the ridges 36 as the jig 43 passes. Since it is in the state of being inserted in 38, it will be in the locked state in order from one end to the other end in the longitudinal direction Y. Then, when the jig 43 reaches the other end in the longitudinal direction Y, the cables protection and guide device 11 having the cylindrical wall portion 40 along the longitudinal direction Y is formed.

  As shown in FIG. 1, FIG. 5 and FIG. 6, the cable protection and guide device 11 having the cylindrical wall portion 40 formed in such a manner can be displaced while curving a middle portion in the longitudinal direction Y thereof. It is attached to the robot 12 in the state. That is, in the robot 12, the base member 13, the intermediate member 14 and the arm member 15 are provided with a plate-like support portion 50 for supporting the cylindrical wall portion 40 in the cable protection and guide device 11. There is. In FIG. 1, support portions 50 are provided at one portion of the outer peripheral surface of the base member 13, at one portion of the outer peripheral surface of the intermediate member 14, and at one portion of the side surface on the tip end side of the arm member 15. In the support portion 50, a hole (not shown) similar to the hole 47 formed in the knob portion 45 of the jig 43 is formed.

  Then, when attaching the cable protection and guide device 11 to the robot 12 via such a support portion 50, the first locking portion 33 and the second locking portion 34 of the sheet 21 are locked to be tubular. The jig 43 used when forming the wall 40 is used. That is, the first engaging groove 48 and the second engaging groove 49 of the engaging portion 46 of the jig 43 are fixed to the cylindrical wall portion 40, and the first engaged portion 41 of the cylindrical wall portion 40 is formed. The second engaging portion 42 is engaged from one end or the other end in the longitudinal direction Y so as to slide along the longitudinal direction Y in a state of being engaged with the second engaged portion 42. Then, since the engagement state of the first locking portion 33 and the second locking portion 34 is held by the engagement portion 46 of the jig 43, the cable protection and guide device 11 has, for example, the cylindrical wall portion 40. Even when the middle portion in the longitudinal direction Y is displaced with twisting, the locked state of the first locking portion 33 and the second locking portion 34 is maintained without being released. In this respect, the jig 43 functions as a locking release restricting member that restricts the release of the locked state between the first locking portion 33 and the second locking portion 34 of the cylindrical wall portion 40.

  As shown in FIGS. 1, 5 and 6, when the cylindrical wall portion 40 in the cable protection and guide device 11 is supported by the support portion 50 on the robot 12 side using the jig 43, the jig 43 is used. The knob 45 is fixed to the support 50 on the robot 12 side using the fixing member 51. That is, in a state where the hole 47 of the knob 45 and the hole (not shown) of the support 50 in the jig 43 are aligned, the knob which is an alignment of the fixing member 51 made of, for example, a binding band, a locking pin, a rivet The jig 43 is fixed to the support 50 by inserting and tightening the holes 45 of 45 and the holes of the support 50. In this respect, the knob 45 of the jig 43 functions as a fixing part fixed to members (the base member 13, the intermediate member 14 and the arm member 15 in the present embodiment) which move relative to each other in the robot 12 .

  In the case of FIG. 1, one end, the middle and the other end of the cylindrical wall 40 in the longitudinal direction Y are the jigs 43 and the support members 50 of the base member 13, the intermediate member 14 and the arm member 15. The fixing member 51 is used for fixing. In this case, when the base member 13 is a first member, the intermediate member 14 and the arm member 15 correspond to a second member that moves relative to the first member (base member 13). Then, when one end portion fixed to the base member 13 as the first member in the longitudinal direction Y of the cylindrical wall portion 40 is a first portion, it is fixed to the intermediate member 14 or the arm member 15 as the second member. The intermediate portion and the other end correspond to a second portion separated from the first portion (one end) in the longitudinal direction Y of the cylindrical wall portion 40.

  In the state shown in FIG. 1, when the robot 12 operates and the intermediate member 14 and the arm member 15 rotate or swing relative to the base member 13 to move relative to each other, the cable protection and guide device 11 follows the movement. The middle portion in the longitudinal direction Y of the wall portion 40 is displaced while being curved. In the case of the present embodiment, in the longitudinal direction Y of the cylindrical wall portion 40, a portion fixed to each of the support portions 50 of the base member 13, the intermediate member 14 and the arm member 15 via the jig 43 One part and the second part move relative to one another with three-dimensional movement. Then, a twist occurs in an intermediate portion in the longitudinal direction Y in the cylindrical wall portion 40, and the first lock portion 33 and the second lock portion 34 are likely to be released from the locked state by the twist.

  However, in the case of this embodiment, the jig 43 attached to the one end, the middle and the other end in the longitudinal direction Y of the cylindrical wall 40 is the first locking portion 33 by the engagement portion 46. And the second locking portion 34, the locking state between the first locking portion 33 and the second locking portion 34 is released even when such a twist occurs. Is regulated. Further, since the jig 43 relatively moves in a state in which the engaging portion 46 can slide in the longitudinal direction Y of the cylindrical wall portion 40, the cable protection and guide device 11 bends the cylindrical wall portion 40, etc. Displacement movement is not inhibited.

According to the above embodiment, the following effects can be obtained.

In this respect, in the present embodiment, such a risk is caused by the jigs 43 attached at positions corresponding to the support portions 50 on the robot 12 side in the longitudinal direction Y of the wall portion 40 functioning as the locking release regulating member. Is reduced. Therefore, even when twisting occurs in an intermediate portion in the longitudinal direction Y of the cylindrical wall portion 40 surrounding the accommodation space 28 in which the cables 27 are accommodated in a long extension state, the cable from the inside to the outside of the accommodation space 28 It is possible to reduce the possibility of the class 27 jumping out.

Therefore, the function of restricting the release of the locked state between the first locking portion 33 and the second locking portion 34, and the first member (for example, the intermediate member 14) and the second member (for example, the arm) that move relative to each other It is possible to combine the function of fixing the first part (for example, the middle part) and the second part (for example, the other end) of the cylindrical wall 40 to the member 15). Can contribute to

  (3) A jig 43 functioning as an unlocking restricting member is attached to the cylindrical wall portion 40 in accordance with relative movement between the first member (for example, the intermediate member 14) and the second member (for example, the ar member 15) Twisting or misalignment may occur in the first portion (for example, the middle portion) or the second portion (for example, the other end). In such a case, the jig 43 functioning as the locking release regulating member slides relative to the longitudinal direction Y of the sheet 21 which is also the longitudinal direction Y of the wall portion 40 to absorb twisting and positional deviation. Therefore, even when such a twist or positional deviation occurs, the cable protection and guide device 11 can stably guide the movement of the cables 27 without being impeded by the movement of the cylindrical wall portion 40. it can.

  (4) First locking portion 33 connecting the first end 31 and the second end 32 in the short direction X of the sheet 21 to form the cylindrical wall 40 surrounding the housing space 28 The locking state between the second locking portion 34 and the second locking portion 34 is easily detached from the portion of one end portion or the other end portion in the longitudinal direction Y of the wall portion 40. In this respect, in the present embodiment, a jig 43 which functions as a locking release restricting member is attached to one end and the other end of the cylindrical wall 40 in the longitudinal direction Y. Therefore, it is difficult to release the locked state of the first locking portion 33 and the second locking portion 34 that connect the first end 31 and the second end 32 in the short direction X of the sheet 21. it can.
