[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod magazine for accommodating a weft rod to be inserted between a plurality of parallel warp rods arranged in a rod type three-dimensional loom. .

[0002]

2. Description of the Related Art The present inventors have installed a rod magazine on a three-dimensional loom and supplied various weft-direction rods to be inserted between warp-direction rods in accordance with the progress of weaving. We are developing a loom. An example of this three-dimensional loom is shown in FIG. The three-dimensional weaving machine shown in the figure inserts the weft direction rod group 2 between the warp direction rod groups 1, and the machine frame 10 includes a large number of the above-mentioned rods as the warp direction rod group 1 in parallel at required intervals. Holding device 1 for holding in a state
1, and a rod holding base 12 for supporting the lower ends of the warp-direction rods 1 and pulling out the woven three-dimensional fabric 3 downward, and driving means for moving the rod holding base 12 up and down. (Not shown).

The machine frame 10 is also provided with two sets of latitudinal rod insertion devices 13 for inserting the latitudinal rod groups 2 into the longitudinal rod groups 1 from two directions orthogonal to each other. . In these latitudinal rod inserting devices 13, a large number of push rods 15 are attached to a driving member 16 driven by an actuator 14 such as a fluid pressure cylinder, and the lowermost stage in a magazine 18 in which a large number of latitudinal rod groups are arranged and housed. The latitudinal rod 2 is pushed by the push rod 15 to be inserted between the longitudinal rods 1.

As shown in FIG. 7, the magazine 18 stores therein the weft direction rods 2 in an array state, and sequentially delivers the weft direction rods 2 as the weaving progresses. The front plate 21 and the rear plate 22 located at the front and rear, the left and right side plates 23, 23, and the bottom plate 24 are provided.
The inner surfaces of 1 and the rear plate 22 are provided with concave grooves 25 and 26 for accommodating and guiding the tips of the latitudinal rods, respectively. Therefore, the latitudinal rod 2 having both ends inserted in the concave grooves 25 and 26 is sequentially fed into the rod feeding groove 27 at the rod feeding position of the bottom plate 24 of the magazine 18.
The tip of the push rod 15 has the rod feeding groove 2
It is arranged so as to face the base end of the latitudinal rod 2 in 7.

However, in such a three-dimensional loom, there are various problems in manufacturing the rod magazine, accommodating the weft direction rod in the rod magazine, and feeding the weft direction rod for weaving from the rod magazine. I was able to confirm that there was a possibility of trouble.

To explain this concretely, first, the guide grooves 25 and 26 provided in the front plate 21 and the rear plate 22 are provided.
In consideration of bending of the rod, etc., it is desirable to make it to a certain depth in order to perform stable guide, but for convenience of machining, a depth of about 3 times the width is economical. However, it is impossible to cut an extremely deep groove, and it is necessary to perform electric discharge machining or the like, which increases the processing cost. Then, the concave grooves 25, 26
As shown in FIG. 8, when the rod is made shallow, not only does the bent rod 2 hinder the feeding of the rod guided by the adjacent concave grooves 25 and 26, but also the rod feeding groove 2 of the bottom plate 24 is provided.
I can't get to 7.

Further, in the rod magazine, a rod array body in which rod materials are cut into a required length and arranged,
It is necessary to store it in that arrangement state in advance,
Even when the rod array is mechanically fed into the groove of the rod magazine, there are the following problems.

That is, when the rods are fed into the rod magazine, as illustrated in FIG. 9A, the rod magazine is attached to the feeding guide 28 of the rod array 5 in the pre-process apparatus for processing the rod material. The rod array 5 is fed all at once from the feed guide 28 with the feed inlets formed by the guide grooves 25 and 26 of the front plate 21 and the rear plate 22 of 18 facing each other and the feed inlets aligned. But
It is difficult to make the delivery inlets exactly coincide with each other due to variations in dimensions among the magazines.

Therefore, as shown in the figure, when the positioning error is absorbed by chamfering 29 at the entrance of the guide grooves 25, 26 in the magazine, the chamfering 2
The arrangement of the rod array body 5 is disturbed at the portion 9 and a new problem occurs that stable feeding becomes difficult. Further, since the latitudinal direction rod 2 has a cross section of about 0.4 to 0.8 mm square, the gap between the delivery guide 28 and the rod magazine 18 when the rod array 5 is fed is 0 to.
It is required to be 0.1 mm, but it is very difficult to perform positioning with such accuracy, and if the gap becomes large as shown in FIG. Will be disturbed. Moreover, in extreme cases,
As shown in FIG. 6C, the delivery guide 28 and the delivery inlet of the magazine 18 cannot be aligned with each other, and in some cases, the delivery cannot be performed.

EXAMPLE A rod used for weaving a three-dimensional woven fabric in the present invention is a rod formed by previously binding a large number of fibers in the same direction with a matrix to form a rod. In the rod-type three-dimensional loom, the weaving of the three-dimensional fabric by accommodating it in the rod magazine and successively inserting it between the warp rods, and storing a large number of those weft rods in the rod magazine, The rod arrays are formed by arranging the weft direction rods in parallel in a plane and are accommodated from above the magazine, and when the rods are inserted into the longitudinal rod group, they are sequentially delivered from below the magazine.

FIG. 1 is an exploded view showing the construction of a rod magazine of the present invention for accommodating such a rod array, and FIGS. 2 and 3 show the rod magazine delivery of the rod array in a pre-process apparatus. It is shown in relation to the guide. The rod magazine 30 includes a bottom plate 31 on which the lowermost rod of the rod array 5 is placed,
The front plate 32 and the rear plate 33, which are located in front of and behind the rod array body 5, are arranged in parallel between the left and right side plates 34, 34, and the side plates so as to house each rod array body 5 in a compartment. And a large number of partition plates 35.

The lower edge of each partition plate 35 is fitted in a groove 37 provided in a row on the bottom plate 31, and the front and rear edges of the partition plate 35 are fitted to the front plate 3.
2 and the rear plate 33 so as to be fixed by being fitted in grooves 38 and 39 which are vertically provided in parallel with the rod array 5 between the partition plates.
To form the accommodation gap. In addition, each partition plate 35
At the front and rear ends of the base plate 31, there are provided bases 40 that slightly project from the grooves 37 of the bottom plate 31 and support the lower ends of the front and rear plates.
By mounting and fixing the front plate 32 and the rear plate 33 on the 0, the lower edge of the front plate and the rear plate is the lowermost latitudinal rod from the upper surface of the bottom plate 31 and the push rod 1 for pressing and inserting the rod.
5 (FIG. 6) is arranged through a gap into which 5 (FIG. 6) is inserted.

Therefore, the lowermost latitudinal rod is the bottom plate 3
1, the upper surface of the convex portion between the grooves 37 is used as a guide surface, each partition plate 35 guides the side surface of the stored rod array 5, and the lower surfaces of the front plate 32 and the rear plate 33 are the upper surfaces of the insertion rod 2 and the push rod 15. And guides the accumulated rods, thereby forming a seamless guide surface.

When the weft rods are guided by such a magazine 30, since the accommodating portions of the rod arrays are separated, not only the rods are reliably guided, but also abnormal rods are adjacent to each other. The arrangement of the rod array body is not disturbed, and it is also possible to accommodate rods of different sizes in one magazine and accommodate changes in the fabric size. Moreover, since the guide surface has no seam at all, the latitudinal rods accommodated in the magazine are sequentially smoothly moved to the lowermost insertion position, and further, the latitudinal rod 2 is delivered very smoothly by the push rod 15. Will be possible.

On the other hand, in order to feed the rod array 5 into the magazine, the upper side of the partition plate 35 has an uneven shape which is not parallel to the bottom plate 31 by forming a plurality of convex portions 43, and The shape is as shown in FIG. 2 and FIG.
It is assumed that the shape substantially coincides with the shape of the outlet of the delivery guide 46 of the pre-process apparatus for delivering the rod to the magazine 30, and that at least the top of the convex portion 43 of the upper side of the partition plate 35 is clearly shown in FIG. As shown, a chamfer 44 is provided so that the plate edge becomes thin.

With this structure, as will be described below, it is possible to absorb the gap and step between the rod and the delivery guide 46 of the preceding process apparatus when the rod is fed into the magazine. That is, as is clear from A of FIGS. 3 and 4,
A plurality of convex portions 43 are formed on the partition plate 35, and the convex portion 4 fitted between the convex portions 43 is also provided at the delivery port of the delivery guide 46.
8 is provided, the shapes thereof are approximately matched so as to be joined to each other, and the tip of the convex portion 43 is chamfered 44, so that the rod array 5 is delivered from the delivery guide 46 in the preceding process apparatus. In this case, first, a part of the rod is fed between the predetermined partition plates 35 at the chamfered portion 44 at the tip of the convex portion 43 of the partition plate 35.

In this case, even if the degree of chamfering of the tip of the convex portion 43 is increased, the arrangement disorder as described with reference to FIG. 9C does not occur. Further, since each rod is always guided by either the convex portion 43 of the partition plate 35 or the convex portion 48 of the delivery guide 46, there is no disorder in the arrangement as described with reference to FIG. 9A. Therefore, the rod array 5 is
The sheet is smoothly fed between the predetermined partition plates, and is reliably delivered from the delivery guide 46 to the magazine 30.

Further, as shown in FIG. 4B, even if there is a step due to a positioning error between the delivery guide 46 and the insertion gap of the rod array 5 between the partition plates 35 in the magazine 30, the partition plate 35 will be affected. When the partition plate 35 is made of a flexible material to some extent while the chamfering 44 is performed,
After a part of the rod is once fed between the partition plates 35, the step can be absorbed by them as shown in FIG.

Further, the side plate 34 and the partition plate 35 mentioned above.
In the rod array body, holes 51 and 52 having substantially the same size are bored at the same position within a range where the rod array body is not disturbed, so that the feeding state of the stored rod array body 5 can be monitored. There is. Although the arrangement of the rods in the magazine 30 can be visually observed through the holes 51 and 52, as shown in FIG. 5, a CCD camera 54 is provided on one side plate 34 and its output is output. Is introduced into the image processing device 55 to detect an abnormal array of rods, and when an abnormal array is detected, a stop signal for stopping the rod feeding actuator 57 is output to the rod feeding device controller 56. be able to. In the above,
