EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of the feed conveyance apparatus of this invention and its disk cable tension provision mechanism is demonstrated with reference to drawings.

As shown in FIG. 1, the feed conveying apparatus 1 of the present invention is provided with a plurality of feeders through feed drop pipes 6, 6, ... maintained at predetermined intervals in the pipe 3 connected to the endless. (7, 7, ...) is provided, and the disc cable (2) having the disc (2b) fixed to the flexible wire (2a) connected to the endless at a predetermined interval is inserted into the pipe (3). The disk cable 2 is made to run in the direction of an arrow x by the drive device 4 through.

In the figure, a feed inlet 5a is formed at the lower end of the feed hopper 5 indicated by a dashed-dotted line, a feed dropping opening 6a is formed at the lower end of the feed drop tube 6, and the feed S is The feed inlet 5a is introduced into the pipe 3 and is conveyed into the pipe 3 by the disk cable 2 so as to be fed into the feed feeder 7 from the feed drop opening 6a.

The corner joint 8 in which the bent pipe forming members 9 and 10 are in contact with and fixed to the corner portions 3a of the pipe 3 at the sharp portions 9a and 10a, as shown in FIGS. 4 and 5. Is excreted.

The corner joint 8 has an outer angle θ of the bent pipe portion 11 at 90 °, and the bent pipe portion 11 is formed with a plurality of protrusions 12, 12, ... protruding inward. . Moreover, the contact members 13, 13, and 14 which are rod members which have a circular cross section curved by the radius of curvature corresponding to the bending pipe part 11 are provided.

According to the corner joint 8, as shown in FIG. 5, since the main surface of the disk 2b is in point contact with the contact member 13, 13, 14 or the projections 12, 12, ..., the disk ( The contact area between the main surface of 2b) and the inner surface of the bent pipe portion 11 becomes small, the contact area with the feed S is also reduced, and the frictional force can be reduced, thereby greatly reducing the load on the wire 2a. .

Unlike the conventional feed conveying apparatus 101, the feed conveying apparatus 1 of this invention does not provide the disk cable tension provision mechanism 112 in the drive apparatus 104, As shown in FIG. 1 and FIG. The drive device 4 and the disc cable tension applying mechanism 15 are separated, and the disc cable tension applying mechanism 15 is disposed below the drive device 4.

As shown in FIG. 7, the drive device 4 includes a drive sprocket 17 at an approximately center portion of the upper side of the housing 16 having the side wall portion 16a, the inclined wall portion 16b, and the bottom wall portion 16c. Exposed, the cable inlet 18 is formed in the side wall part 16a, and the cable outlet 19 is formed in the bottom wall part 16c.

Further, the motor slide moving mechanism 20 is provided on the rear side of the housing 16, and the drive motor 21 connected to the drive sprocket 17 is slid properly in the horizontal direction so that the disc cable 2 is properly tensioned. Can be added.

According to the drive device 4, the feed S conveyed from the pipe portion 3H provided in the horizontal direction is introduced into the housing 16 from the cable introduction port 18, and the inclined wall portion 16b is caused by gravity. Flows downward along the line, is discharged to the pipe portion 3V disposed vertically from the cable outlet 19, and at the same time the drive sprocket 17 is disposed at a position opposite to the inclined wall portion 16a, the feed S ) Does not gradually accumulate in the drive device 4 and does not enter the shaft portion of the drive sprocket 17.

This eliminates the work of removing the feed S accumulated in the drive device 4, cleaning the mechanical parts in the drive device 4, and adjusting them.

As shown in FIG. 6, the disk cable tensioning mechanism 15 is a portion indicated by a dotted line, and the pipe portions 3M and 3N and the corners which are suspended from the drive device 4 so as to be movable in the vertical direction. It consists of joints 8A and 8B.

As shown in Fig. 8, the pipe portion 3M has an inner diameter at an upper portion thereof larger than the outer diameter of the pipe portion 3V so that the pipe portion 3M can slide with the pipe portion 3V. The working plate 23 is fixed to the pipe portion 3V via the support member 22, and the limit switches 25 and 26 are fixed to the pipe portion 3M through the support members 24 and 24. have.

As shown in FIG. 6, the piping part 3N is integrally connected with the piping part 3S arrange | positioned further downstream of the inclination.

The corner joints 8A and 8B have the same configuration as the corner joint 8 disposed at the corner portion 3a of the pipe 3, but the corner joint 8A has an outer angle θ of 90 degrees of the bent pipe portion 11A. The corner joint 8B sets the outer angle θ of the bent pipe portion 11B to 45 degrees.

Since the disk cable tension applying mechanism 15 is suspended from the driving device 4 so as to be movable in the vertical direction, as shown in FIG. 6, the disk cable tension applying mechanism 15 is always vertically lowered by the weight of the member constituting the mechanism. To give power.

Accordingly, the vertical downward force is always applied to the disk cables 2 through which the piping portions 3M and 3N and the corner joints 8A and 8B constituting the disk cable tensioning mechanism 15 are inserted. When the wire 2a of the disk cable 2 is extended, the pipe portion 3M slides vertically downward, and the disk cable tensioning mechanism 15 moves downward to the disk cable 2. Give proper tension all the time.

As described above, according to the disk cable tension applying mechanism 15 of the present invention, without using a mechanical component such as a tension spring or a flow pulley, the accumulated feed S is removed, and the mechanical component is cleaned and adjusted. The disk cable 2 can be automatically given a proper tension at all times without any troublesome work.

In addition, the disk cable tensioning mechanism 15 need not be installed at the position immediately before the feed hopper 105 as the disk cable tensioning mechanism 112 configured in the conventional drive device 104, and the drive device 4 If it is a position suspended and installed below, it can be installed in the appropriate position of the piping path of the feed conveying apparatus 1.

In addition, unlike the conventional disk cable tensioning mechanism 112, since the weight of the pipe portions 3M and 3N and the corner joints 8A and 8B, i. Even if the feed S is filled in the pipe 3, it can be conveyed smoothly by the drive device 4.

In addition, when the disk cable 2 is entangled with mechanical parts such as the drive sprocket 17 due to some reason, the disk cable 2 contracts and expands in appearance, so that the pipe portion 3M slides upward. However, since the actuating plate 23 of the pipe portion 3V then presses the working lever 26a of the limit switch 26 of the pipe portion 3M, the drive motor 21 can be stopped.

On the other hand, when the disk cable 2 extends abnormally or the disk cable 2 is cut off, the pipe portion 3M slides downward, but the working plate 23 of the pipe portion 3V then moves the pipe portion. Since the actuating lever 25a of the limit switch 25 of 3M is pressurized, the drive motor 21 can be stopped.

In this way, when the working plate 23 is fixed to the pipe portion 3V and the limit switches 25 and 26 are fixed to the pipe portion 3M in the disk cable tensioning mechanism 15, an unforeseen situation may occur. In this case, the drive motor 21 can be automatically stopped, whereby the livestock and workers in the vicinity of the feed conveying apparatus 1 can be secured, and the feed conveying apparatus 1 can be prevented from being damaged. .

On the other hand, the sensing device for detecting that the pipe portion 3M slides a predetermined distance in the vertical direction is not limited to that by the operation plate 23 and the limit switches 25 and 26, and of course, appropriate sensing devices such as an optical sensor may be used. It can be adopted.

In the feed conveyance apparatus 1 of this invention, the feed S conveyed horizontally is dropped vertically downward from the drive apparatus 4, and the disk cable tension provision mechanism 15 is lowered below the drive apparatus 4 Since the suspension is mounted so as to be movable in the vertical direction, the drive device 4 and the disk cable tension applying mechanism 15 are configured to feed the feed hopper 5 and the first feed feeder as shown in FIG. 7) in the middle of the pipe (3) connecting, as shown in Figure 2, in the middle of the pipe (3) connecting between the feeder (7, 7), or as shown in Figure 3 It is arranged in the middle of the pipe (3) connecting the feeder (7) and the feed hopper (5).

As in the related art, although the feed S is conveyed vertically or inclined upward from the feed inlet 5a of the feed hopper 5 and the feed S is blocked in this portion, the driving tends not to change. Since the apparatus 4 is excreted at a position substantially higher than the feed inlet 5a, the feed S is taken out and transported from the upper side, and in this respect, the driving force of the driving sprocket 17 can be greatly reduced.

However, as shown in FIG. 3, in the part of the piping 3 connected 200 m or more from the feed hopper 5, the disk cable 2 of the disk cable 2 is also resisted by the resistance by the feed S conveyed into the piping 3 as well. Since the tension is increased, the drive device 4 and the disk cable tensioning mechanism 15 are placed in the middle of the pipe 3 connecting the feed hopper 5 and the original feeder 7 as shown in FIG. It is most desirable to excrete.

It is also preferable to employ the drive device 34 as shown in Figs. 10 to 12 instead of the drive device 4.

The drive device 34 connects the drive motor 41 to the corner joint 38 composed of the covers 35 and 36 and the drive sprocket 37 through the drive shaft 39 and the shaft joint 40.

The sprocket accommodating part for accommodating the bent pipe part 42 and the drive sprocket 37 for conveying the disc cable 2 by fastening the sharp parts 35a and 36a of the covers 35 and 36 by mutual contact and fastening with a bolt and a nut. 43 is formed, a cable inlet 44 is formed at one end of the bent pipe part 42, and a cable outlet 45 is formed at the other end.

According to the drive device 34, the feed S conveyed from the piping portion 3H disposed in the horizontal direction is introduced into the corner joint 38 from the cable inlet 44, and gravity and the disk cable 2 It flows in the bent pipe part 42 by this, and is discharged | emitted from the cable discharge port 45 to the piping part 3V provided in the perpendicular direction.

In the drive device 34, a mechanism for applying tension to the disk cable 2 is not particularly provided. Therefore, the feed S accumulated in the drive device 34 is removed to adjust the tension, and the drive device 34 It is not necessary to clean and adjust the mechanism parts inside.

Instead of the disk cable tensioning mechanism 15, a disk cable tensioning mechanism 55 as shown in Figs. 13 and 14 can be employed.

The disk cable tensioning mechanism 55 is a portion shown by the dotted line, and the pipe portions 3P, 3Q, 3R and the corner joints 8C, 8D which are installed by being suspended in a vertically movable direction below the drive devices 4, 34. It consists of

The piping part 3P makes the inner diameter of the upper part larger than the outer diameter of the said piping part 3V, and is slidably movable with the piping part 3V. The working plate 57 is fixed to the pipe portion 3V via the supporting member 56. The limit switches 59 and 60 are fixed to the pipe portion 3P via the supporting members 58 and 58.

The piping part 3Q makes the outer diameter of the upper part smaller than the inner diameter of the piping part 3T arrange | positioned further downstream downstream, and is slidable with the piping part 3T mutually. And the working plate 62 is fixed to the piping part 3Q via the support member 61, and the limit switches 64 and 65 are fixed to the piping part 3T via the support members 63 and 63, and have.

3R of piping parts connect between corner joint 8C, 8D, and are arrange | positioned in the substantially horizontal direction.

The corner joints 8C and 8D have the same configuration as the corner joint 108 incorporating a wheel disposed in the corner portion 103a of the pipe 103 in the conventional feed conveying apparatus 101.

As shown in FIGS. 13 and 14, the disk cable tensioning mechanism 55 is also suspended from the driving apparatuses 4 and 34 so as to be movable in the vertical direction, and thus the member constituting the mechanism at all times. The force in the vertical downward direction is given by the weight of.

As a result, the vertical downward force is always applied to the disk cable 2 through which the pipe portions 3P, 3Q, 3R and the corner joints 8C, 8D constituting the disk cable tensioning mechanism 55 are inserted. When the wire 2a of the disk cable 2 is stretched, the pipe portions 3P and 3Q slide vertically downward, and the disk cable tension applying mechanism 55 moves downward, so that the disk cable ( A predetermined tension is always given to 2).

In this way, the disk cable tension applying mechanism 55 does not use any mechanical parts such as tension springs or flow pulleys, and removes the accumulated feed S and cleans and adjusts the mechanical parts. It is possible to automatically give the disc cable 2 an appropriate tension at any time.
