Description

[0001] GUIDE DEVICE FOR ELONGATED OBJECT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guiding device for guiding a long object guided by the movement of a moving part in a state of accommodating a long object such as a flexible cable or a hose for feeding or supplying fluid to a moving part of a machine tool or the like.

Conventionally, as a guiding device for this type of long object, it is known to accommodate long objects in the receiving space. The accommodation space is constituted by a space defined by bending the extruded elongated elastomeric resin sheet from the bent portion to both sides. The long object is accommodated along the longitudinal direction of the sheet in the accommodating space (see, for example, Patent Document 1). The elastomeric resin sheet has an outer peripheral wall forming portion, two side wall forming portions respectively disposed through bending portions on both sides of the outer peripheral wall forming portion, and two inner peripheral wall forming portions provided respectively at the two side wall forming portions .

One of the two inner peripheral wall forming portions is provided with a female inner peripheral wall portion. And the other of the two inner peripheral wall forming portions is provided with a male inner peripheral wall portion. The male type circumferential wall portion is configured to be fittable with the female type inner circumferential wall portion. When forming the accommodating space of the long object, the two inner peripheral wall forming portions are closed while the female inner peripheral wall portion and the male inner peripheral wall portion are fitted to each other along the longitudinal direction of the sheet, An opposed flat surface is formed.

In this case, as shown in Fig. 5 (a) of Patent Document 1, the female type inner circumferential wall portion has the concave groove and the male type inner circumferential wall portion has the convex portion. The convex portion of the circumferential wall of the male type is inserted into the concave groove of the female type inner circumferential wall portion and caught in the concave groove.

Japanese Patent Application Laid-Open No. 2008-267436

As described above, in the guide apparatus for long objects, the positions of the two engaged portions provided on both sides of the convex portion coincide with each other in the insertion direction of the concave portion of the convex portion. Therefore, when the convex portion is inserted into the concave groove while elastically deforming the concave groove by press-fitting the convex portion from the opening of the concave groove, the convex portion is formed in the concave groove so that the opening is widened to the maximum width of the convex portion including the two to- It is necessary to press-fit it into the groove. As a result, there is a problem that the convex portion can not be easily inserted into the concave groove.

The present invention has been made in view of the problems existing in the prior art. The object of the present invention is to provide a sheet conveying apparatus which is capable of forming a convex portion provided on a first end portion in a short side direction of a sheet when a sheet extending along a long side direction is bent to form a receiving space for accommodating a long object, And a guiding device for a long object which can be easily inserted into a receiving portion provided at two end portions.

Hereinafter, the means for solving the above problems and the effect of the present invention will be described.

A guiding device for a long object which solves the above object is a sheet extending along a longitudinal direction and includes a bent portion extending along the longitudinal direction and a bent portion extending along the longitudinal direction, And the second end of the sheet is bent at the bent portion and the first end and the second end are connected to each other to form a receiving space extending in the longitudinal direction inside the sheet, Guide long objects contained in the accommodation space. The guiding device for the long object has a convex portion provided at the first end portion and a flexible accommodating portion provided at the second end portion and capable of accommodating the convex portion. And the convex portion is received in the accommodating portion when the accommodating space is formed. The convex portion has two engaged portions provided on both sides thereof. The accommodating portion has two opening portions and two engaging portions capable of engaging the two engaged portions when the convex portion is inserted into the accommodating portion through the opening while elastically deforming the accommodating portion to expand the opening. The positions of the two pierced portions in the insertion direction when the convex portion is inserted into the accommodating portion through the opening portion are different from each other.

According to this configuration, when the convex portion is inserted into the accommodating portion through the opening, the two engaged portions disposed on both sides of the convex portion pass through the opening at different timings. As a result, the amount of resilient deformation of the accommodating portion for expanding the opening can be reduced as compared with a configuration in which the two engaged portions pass through the opening at the same timing. Therefore, when the accommodating space for accommodating a long object is formed by bending the sheet extending along the long side direction, the convex portion provided at the first end in the short side direction of the sheet is easily inserted into the accommodating portion provided at the second end Lt; / RTI >

In the guiding device for the long object, the convex portion and the accommodating portion are provided on an inner peripheral wall defining the accommodating space, and the two engaging portions are provided on both sides of the accommodating portion with the opening interposed therebetween And the first to-be-engaged portion is disposed at a position relatively close to the inner peripheral wall, and the second to-be-engaged portion is disposed at a position relatively far from the inner peripheral wall, Is preferably disposed on the front side in the insertion direction with respect to the second engaged portion.

Normally, when the guiding device for a long object is curved such that the inner peripheral wall is inward, a load is applied to the convex portion and the accommodating portion in a direction of pulling the convex portion through the opening of the accommodating portion (the direction opposite to the inserting direction). The load at this time increases as the position is closer to the inner peripheral wall. Therefore, when the position of the first to-be-engaged portion in the inserting direction of the convex portion is the same as the position of the second to-be-latched portion, when the first to-be-latched portion is caught by the latch portion corresponding to the first to- And the load applied to the engaging portion corresponding to the first engaged portion engages with the second engaged portion when the second engaged portion engages with the engagement portion corresponding to the second engaged portion, Is greater than the load applied to the corresponding engaging portion. As a result, the engagement between the first engaged portion and the engagement portion corresponding to the first engaged portion can be easily released, so that there is a problem that the convex portion easily escapes from the accommodation portion. On the other hand, according to the above configuration, the first engaged portion is disposed on the front side of the insertion direction of the convex portion than the second engaged portion. Therefore, when a load in the direction of pulling the convex portion through the opening of the accommodating portion with respect to the convex portion and the accommodating portion is applied, when the second engaged portion is engaged with the engaging portion corresponding to the second engaged portion, And a load applied to the engaging portion corresponding to the second engaged portion is increased to some extent, the first engaged portion is caught by the engaging portion corresponding to the first engaged portion. Therefore, when the first engaged portion is engaged with the engagement portion corresponding to the first engagement portion, the load applied to the engagement portion corresponding to the first engagement portion and the engagement portion corresponding to the first engagement portion, The difference between the load applied to the second engaged portion and the engagement portion corresponding to the second engaged portion is reduced when the first engaged portion and the second engaged portion are engaged with each other, So that the deviation of the load between the parts is suppressed. Therefore, it is possible to prevent the convex portion from escaping from the accommodating portion.

In the guiding device for the long object, it is preferable that, in a state in which the accommodating space is formed, the convex portion and the accommodating portion are disposed outside the accommodating space.

According to this configuration, it is possible to secure a large accommodation space as compared with a configuration in which the convex portion and the accommodation portion are arranged in the accommodation space.

In the guiding device for the long object, it is preferable that, in a state in which the accommodating space is formed, the convex portion and the accommodating portion are disposed in the accommodating space.

According to this configuration, it is possible to reduce the size of the apparatus for a long object, as compared with a configuration in which the convex portion and the accommodation portion are arranged outside the accommodation space.

In the guiding device for the long object, it is preferable that, in a state in which the accommodation space is formed, a plane bisecting the opening portion bisects the convex portion.

With this configuration, when a load is applied to the convex portion and the accommodating portion in a direction in which the convex portion is pulled out through the opening of the accommodating portion (in the direction opposite to the inserting direction), the engaging portions of the engaged portions are engaged It is possible to engage the engaging portion with a good balance of the load between the engaging portion and the engaging portion corresponding to the engaged portion.

According to the present invention, when the accommodating space for accommodating a long object is formed by bending the sheet extending along the long direction, the convex portion provided at the first end in the short-side direction of the sheet can be easily Can be inserted.

The guiding device 11 of the long object guides the long object TK (not shown) in accordance with the reciprocating movement of the moving body (not shown) connected to the first bracket (not shown) while protecting the long object TK accommodated in the accommodating space SK. .

In this case, as shown in Fig. 3, the guiding device 11 for a long object is arranged such that the slit 20 is opened so that the curved portion W is formed in the middle portion thereof. The curved portion W moves along the longitudinal direction Y in accordance with the reciprocating motion along the longitudinal direction Y of the moving body (not shown) connected to the first bracket (not shown).

Examples of the long object TK include a body (e.g., air) and a liquid (for example, an electric wire, an electric wire, etc.) to an electric cable or an optical cable for feeding or signaling a moving object (not shown) A hose for supplying water or oil, etc.), and a long multi-joint member flexibly bendable.

Next, the configurations of the first connection portion 17 and the second connection portion 18 will be described in detail.

As shown in Fig. 4, the first connection portion 17 includes a flat base portion 30 and a convex portion 31. The base portion 30 is provided so as to be orthogonal to the first inner circumferential wall forming portion 16a on the side opposite to the receiving space SK from the tip end of the first inner circumferential wall forming portion 16a. The convex portion 31 is provided at a central portion on the surface of the base portion 30 close to the second inner circumferential wall forming portion 16b and has a short side direction X perpendicular to the base portion 30 . The base portion 30 and the convex portion 31 are formed over the entire longitudinal direction Y of the guide device 11 of a long object.

The convex portion 31, when viewed from the longitudinal direction Y, has a generally rounded shape with its leading end rounded. The convex portion 31 has two pierced portions provided on both sides of its distal end portion. These engaged portions are formed so as to form a right triangle when viewed from the longitudinal direction (Y). The two engaging portions constituting the first engaged portion 32 and the second engaged portion 32 disposed relatively far from the inner peripheral wall 21 constitute the first engaged portion 32, Thereby constituting the latching portion 33. [ The side of the front end portion of the convex portion 31 on the side of the first engaged portion 32 constitutes the first inclined face 32a and the second engaged portion 33 on the front end of the convex portion 31 forms the first inclined face 32a, Side surface constitutes a second inclined surface 33a.

The second connection portion 18 has a groove forming portion 36 formed on a surface opposite to the accommodation space SK at the center of the short side direction X of the second inner peripheral wall forming portion 16b have. The groove forming portion 36 is formed so as to have an L-shape when viewed from the longitudinal direction Y. The second inner circumferential wall forming portion 16b and the groove forming portion 36 form the receiving groove 35 capable of accommodating the convex portion 31. [ The groove forming portion 36 is formed over the entire long direction Y of the guide device 11 of a long object. The second connecting portion 18 also has an opening 37 which is opened between the tip end of the second inner peripheral wall forming portion 16b and the tip end of the groove forming portion 36. [

The opening 37 has a first inside edge near the second inner circumferential wall forming portion 16b and a second inside edge far from the second inner circumferential wall forming portion 16b. A first latching portion 38 as a latching portion is provided at the first inner edge of the opening 37 at the distal end of the second inner peripheral wall forming portion 16b. The first latching portion 38 is formed so as to form a right triangle when viewed from the longitudinal direction Y. [ In other words, the first latching portion 38 is provided so as to protrude so as to narrow the width of the opening 37. [

At the tip of the groove forming portion 36, a second latching portion 39 as a latching portion is provided at the second inside edge of the opening 37. [ The second latching portion 39 is formed so as to form a right-angled triangle when viewed from the longer side (Y). In other words, the second latching portion 39 is provided so as to protrude so as to narrow the width of the opening portion 37. The first engaging portion 38 and the second engaging portion 39 are disposed on both sides of the second connecting portion 18 with the opening 37 therebetween. In this case, the first engaging portion 38 and the second engaging portion 39 are plane symmetric with respect to the plane F bisecting the opening 37.

The first front end face 38a of the first engaging part 38 and the second front end face 39a of the second engaging part 39 are opposed to each other with the opening 37 interposed therebetween. The first front end face 38a and the second front end face 39a are each inclined with respect to the plane F so that the width of the opening 37 becomes narrower toward the receiving groove 35. [ The first front end face 38a and the second front end face 39a correspond to the first inclined face 32a and the second inclined face 33a of the convex portion 31 respectively. The width of the opening 37 is set to be narrower than the maximum width of the convex portion 31 and to be substantially equal to the width of the proximal end portion of the convex portion 31.

The first engaging portion 38 and the second engaging portion 39 are formed such that the second connecting portion 18 is elastically deformed so that the opening 37 is widened and the convex portion 31 is inserted into the receiving groove 35 The first to-be-latched portion 32 and the second to-be-latched portion 33 can be engaged, respectively. When the convex portion 31 in the first engaged portion 32 and the second engaged portion 33 of the convex portion 31 are inserted into the receiving groove 35 through the opening 37, (The direction from the right to the left along the short side direction X in Fig. 4) are different from each other.

More specifically, the first engaged portion 32 is disposed on the front side (left side in FIG. 4) of the insertion direction of the convex portion 31 than the second engaged portion 33. That is, in the state in which the convex portion 31 is inserted into the receiving groove 35 and the accommodation space SK is formed, the distance from the first engaged portion 32 to the opening 37 in the short- The distance is set longer than the distance from the second engaged portion 33 to the opening 37 in the short direction X. [

In this case, the plane F bisecting the opening 37 divides the convex portion 31 into two halves. The convex portion 31 and the second connection portion 18 are disposed outside the accommodation space SK. In the present embodiment, the second connecting portion 18 constitutes a receiving portion.

Next, in the guide device 11 for a long object according to the embodiment configured as described above, the operation when the first connecting portion 17 and the second connecting portion 18 are connected, that is, through the opening 37 The operation when the convex portion 31 is inserted into the receiving groove 35 will be described.

When the convex portion 31 is to be inserted into the receiving groove 35 through the opening portion 37 along the short side direction X as shown in Figs. 2 and 4, The first inclined face 32a and the second inclined face 33a of the convex portion 31 are located on the first front end face 38a of the first engaging portion 38 and the second front end face 38a of the second engaging portion 39, Respectively, with respect to the distal end surface 39a. Subsequently, when the convex portion 31 is pressed toward the inside of the receiving groove 35 along the short direction X, the first inclined face 32a and the second inclined face 33a of the convex portion 31 are pressed against the first And slides with respect to the first front end face 38a of the engaging portion 38 and the second front end face 39a of the second engaging portion 39, respectively.

5 (b), the first inclined face 32a and the second inclined face 33a of the convex portion 31 are inclined with respect to the first front end face 38a of the first engaging portion 38, And presses the second distal end face 39a of the second engaging portion 39, respectively. As a result, the distal end portion of the second inner peripheral wall forming portion 16b and the distal end portion of the groove forming portion 36 are elastically deformed so that the opening 37 is widened.

At this time, the first engaged portion 32 of the convex portion 31 is shorter than the second engaged portion 33 in the inserting direction of the convex portion 31 (in Figs. 5 (a) to 5 (d) (Left side in Figs. 5 (a) to 5 (d) in the direction from the right to the left along the lateral direction X), the elastic deformation amount of the front end portion of the second inner peripheral wall forming portion 16b Becomes larger than the amount of elastic deformation of the tip end portion of the groove forming portion 36. This is because the inclination angle of the first inclined plane 32a with respect to the plane F is larger than the inclination angle with respect to the plane F of the second inclined plane 33a. At this time, the amount of elastic deformation of the tip end portion of the groove forming portion 36 is made small.

5 (c), when the convex portion 31 is pressed toward the inside of the receiving groove 35 along the short-side direction X, the first to-be- And enters the receiving groove 35 before the second receiving portion 33. As a result, the shape of the distal end portion of the second inner peripheral wall forming portion 16b, which has been elastically deformed, is returned to its original shape before the elastic deformation due to its elastic restoring force. At this time, since the pressing force against the second front end face 39a of the second engaging portion 39 by the second inclined face 33a of the convex portion 31 becomes large, the elastic deformation amount of the tip end portion of the groove forming portion 36 It grows.

5 (d), when the convex portion 31 is pressed toward the inside of the receiving groove 35 along the short side direction X, the second engaged portion 33 is received And enters the groove 35. As a result, the shape of the tip end portion of the groove forming portion 36 that has been elastically deformed returns to the original shape before the elastic deformation due to the elastic restoring force of itself.

This completes the connecting operation of the first connecting portion 17 and the second connecting portion 18, that is, the operation of inserting the convex portion 31 into the receiving groove 35 through the opening portion 37. [ When an external force acts on the convex portion 31 in the direction of extracting the convex portion 31 from the inside of the receiving groove 35 through the opening portion 37, the first to- (33) is engaged by the first engaging portion (38) and the second engaging portion (39), respectively.

As described above, in the guiding device 11 for a long object according to the present embodiment, when the convex portion 31 is inserted into the receiving groove 35 through the opening portion 37, The first to-be-engaged portion 32 and the second to-be-engaged portion 33 pass through the opening 37 at different timings. As compared with the configuration in which the first to-be-engaged portion 32 and the second to-be-engaged portion 33 pass through the opening portion 37 at the same timing, the second inner peripheral wall forming portion The maximum value of the sum of the amount of elastic deformation of the front end portion of the groove forming portion 16a and the amount of elastic deformation of the front end portion of the groove forming portion 36 can be reduced.

Therefore, compared with the configuration in which the first to-be-engaged portion 32 and the second to-be-engaged portion 33 pass through the opening portion 37 at the same timing, It is possible to insert the portion 31. [ Therefore, the convex portion 31 can be easily inserted into the receiving groove 35 through the opening 37. [

In the conventional configuration in which the position of the first to-be-engaged portion 32 and the position of the second to-be-operated portion 33 are set to the same position in the insertion direction of the convex portion 31, 6 (a) to 6 (c), taking the action of inserting the convex portion 31 into the receiving groove 35 through the through hole 35 as a comparative example. In the following comparative example, the first to-be-engaged portion 32 and the second to-be-coupled portion 33 of the above embodiment are changed to the first to-be-engaged portion 101 and the second to- . The members other than the first to-be-latched portion 32 and the second to-be-latched portion 33 will be described using the same reference numerals as those in the above embodiment.

When the convex portion 31 is to be inserted into the receiving groove 35 through the opening 37 along the short side direction X as shown in Figure 6A, The inclined face 32a and the second inclined face 33a abut against the first front end face 38a of the first engaging portion 38 and the second front end face 39a of the second engaging portion 39 respectively. Subsequently, when the convex portion 31 is pressed toward the inside of the receiving groove 35 along the short direction X, the first inclined face 32a and the second inclined face 33a of the convex portion 31 are pressed against the first And slides with respect to the first front end face 38a of the engaging portion 38 and the second front end face 39a of the second engaging portion 39, respectively.

6 (b), the first inclined face 32a and the second inclined face 33a of the convex portion 31 are inclined with respect to the first distal end face 38a of the first engaging portion 38, And presses the second distal end face 39a of the second engaging portion 39, respectively. As a result, the distal end portion of the second inner peripheral wall forming portion 16b and the distal end portion of the groove forming portion 36 are elastically deformed so that the opening 37 is widened.

At this time, the position of the convex portion 31 in the inserting direction of the convex portion 31 (the direction from the right to the left along the short side direction X in Figs. 6A to 6C) The amount of elastic deformation of the distal end portion of the second inner peripheral wall forming portion 16b and the amount of elastic deformation of the distal end portion of the groove forming portion 36 are set to be the same, The elastic deformation amount becomes maximum at the same timing.

6 (c), when the convex portion 31 is further pressed toward the inside of the receiving groove 35 along the shorter direction X, the first to-be-engaged portion 101 and the second The engaging portion 102 enters the receiving groove 35. As a result, the shape of the distal end portion of the second inner circumferential wall forming portion 16b and the shape of the tip end portion of the groove forming portion 36, which have been elastically deformed, return to their original shape before elastic deformation due to their elastic restoring forces. This completes the operation of connecting the first connecting portion 17 and the second connecting portion 18, that is, the operation of inserting the convex portion 31 into the receiving groove 35 through the opening 37.

As described above, in the configuration of the comparative example, when the convex portion 31 is inserted into the receiving groove 35 through the opening portion 37, the first to-be-engaged portion 101 and the second to- The second engaging portion 102 passes through the opening 37 at the same timing. As compared with the configuration of the above-described embodiment in which the first to-be-engaged portion 32 and the second to-be-coupled portion 33 pass through the opening portion 37 at different timings, The maximum value of the sum of the amount of elastic deformation of the tip end portion of the inner circumferential wall forming portion 16b and the amount of deformation of the tip end portion of the groove forming portion 36 becomes large.

Therefore, compared with the configuration of the above-described embodiment in which the first to-be-engaged portion 32 and the second to-be-engaged portion 33 pass through the opening portion 37 at different timings, A larger force is required to insert the convex portion 31 into the receiving groove 35 through the opening 37 and it becomes difficult to insert the convex portion 31 into the receiving groove 35. [

Next, the operation when the connection state between the first connection part 17 and the second connection part 18 is released, that is, the operation when the guide device 11 of the long object of the above embodiment is used, The action of the insertion of the protruding portion 31 through the opening 37 will be described.

When the moving body (not shown) reciprocates along the longitudinal direction Y, the guiding device 11 of the long object moves the curved portion W in the longitudinal direction Y so as to follow the moving body (not shown) As shown in Fig. A long object (TK) is accommodated in the accommodation space (SK) of the guide device (11) of a long object. The long object TK is guided by the guiding device 11 of the long object in accordance with the movement of the moving body (not shown) while being protected in the containing space SK. At this time, as shown in Fig. 3, in the curved portion W of the guiding device 11 of a long object, the first inner circumferential wall forming portion 16a and the second inner circumferential wall forming portion 16b , And a force in the direction of separating them along the short-side direction (X), respectively.

Therefore, since the deviation of the load between the first to-be-engaged portion 32 and the second to-be-latched portion 33 is suppressed, the engagement state of the first to-be-engaged portion 32 by the first engagement portion 38 maintain.

Subsequently, when the separating force continues to be applied to the first connecting portion 17 and the second connecting portion 18, the leading end of the second inner peripheral wall forming portion 16b is significantly larger than the leading end of the groove forming portion 36 And is elastically deformed. Then, as shown in Fig. 7 (d), the engagement of the first engaged portion 32 by the first engagement portion 38 is released. The engaged state of the second engaged portion 33 by the second engagement portion 39 is released and the convex portion 31 inserted into the receiving groove 35 is released through the opening portion 37. [

In the conventional configuration in which the position of the first engaged portion 32 and the position of the second engaged portion 33 are set to the same position in the insertion direction of the convex portion 31, 8 (a) and 8 (b), the operation when the convex portion 31 inserted into the through hole 37 is passed through the opening 37 will be described as a comparative example. In the following comparative example, the first to-be-engaged portion 32 and the second to-be-coupled portion 33 of the above embodiment are changed to the first to-be-engaged portion 101 and the second to- . The members other than the first to-be-latched portion 32 and the second to-be-latched portion 33 will be described using the same reference numerals as in the above-described embodiment.

When a force acts on the first inner circumferential wall forming portion 16a and the second inner circumferential wall forming portion 16b in the direction of separating the first inner circumferential wall forming portion 16a and the second inner circumferential wall forming portion 16b from each other along the short side direction X, A force acts on the connecting portion 18 in the direction in which the convex portion 31 is pulled out from the receiving groove 35 through the opening portion 37 (the opposite direction to the inserting direction), that is, the separating force. 8 (a), the first to-be-engaged portion 101 and the second to-be-coupled portion 102 of the convex portion 31 are engaged with the first engagement portion 38 and the second latching portion 39, respectively.

At this time, the position where the first engaged portion 101 is caught by the first engaging portion 38 and the position between the inner peripheral wall 21 (the first inner peripheral wall forming portion 16a and the second inner peripheral wall forming portion 16b) Is shorter than the distance between the position where the second to-be-latched portion 102 is caught by the second latching portion 39 and the inner peripheral wall 21. The load applied to the first engaged portion 101 and the first engagement portion 38 when the first engaged portion 101 is engaged by the first engagement portion 38 is smaller than the load applied to the first engaged portion 101 The portion 102 is significantly larger than the load applied to the second engaged portion 102 and the second engagement portion 39 when it is engaged by the second engagement portion 39. [
