2. Description of the Related Art For example, at a normal temperature (cold) or a high temperature (hot), a material to be rolled is passed between rotating rolls to form a plate, a shape, a pipe, or the like having a required cross-sectional shape and size. In a rolling line to be rolled, a cutting section provided with a pair of hot saws and the like that can move close to and away from each other along the line is provided downstream of a rolling section that performs rolling. The rolled material that has completed the predetermined rolling step is cut at the front end and the rear end by a pair of hot saws separated by a predetermined distance, whereby the material shown in FIG.
As shown in FIG. 7, a product 91 having a desired overall length is obtained. The product 91 is transported to a downstream collecting yard or the like by a transport conveyor, and an end member (also referred to as a “crop”) 92 formed by cutting is dropped from the conveyor and installed in an underground pit. The crop is stored in a collection bucket. Crop 92 stored in this collection bucket
Is transported to a material factory and used again as a material for the material to be rolled 90.

[0003]

The crop 92 generated in the above-mentioned rolling line is an unnecessary end portion other than the product 91, but is a considerable weight because it is a steel end material. In addition, in the rolling line, materials of various shapes, sizes and materials are rolled in order to cope with various kinds of small-quantity production. Therefore, the crop 92 is not always the same in material and its shape is indefinite, and the weight is further increased. Not constant. Moreover, in the underground pit defined below the cutting section, only enough space for installing one collection bucket is secured, so that all the dropped crops 92 are mixed in the collection bucket. Will be collected. Therefore, the recovered crop 9
In order to reuse the material 2 as a material, it is necessary to sort by shape and material, and it is necessary to arrange personnel for performing the sorting work professionally, and because of the heavy weight, considerable labor is required. Had to be forced. Further, in order to mount the collection bucket filled with the crop 92 from the underground pit to a truck or the like, the collection bucket is lifted using an overhead traveling crane installed in the factory. During the operation, other operations that require the use of the crane cannot be performed, and there is a disadvantage that productivity improvement and reduction of production cost in the factory are hindered.

The stop control is performed each time (this is referred to as “one step”). And one of the 13 hangers 2
When 0 stops at a predetermined position of the receiving station 13, one of the remaining hangers 20 is set to match each of the discharge points 15 a to 15 f at the discharge station 14.

(Regarding the crop transfer device) The receiving station 13 is located at the downstream end of the crop transfer conveyor 82, and between the receiving station 13 and the crop transfer conveyor 82, as shown in FIGS. As shown, a crop transfer device 46 for loading the crop 92 in the bucket 36 of the hanger 20 arriving at the receiving station 13 is provided. The crop transfer device 46 has a configuration in which, for example, an extruded piece 48 is fixed to the tip of a rod 47a of a fluid pressure cylinder 47, and the extruded piece 48 is moved back and forth by controlling the cylinder 47. To move the crop 92 to the bucket 36
It is designed to extrude inside. Receiving station 1
As shown in FIG. 6, a buffer member 49 using pneumatic or hydraulic pressure is disposed below the hanger 20. When the hanger 20 arrives at the receiving station 13, a frame 25 of the hanger 20 is provided. The lower rod 29 is
9 comes into contact with the upper part. That is, the heavyweight crop 92 is loaded into the bucket 36 so as to slide down when it is extruded by the crop transfer device 46, so that the impact force generated by this can be received by the cushioning member 49. Thereby, the structure is such that the load is not applied to the hanger 20 itself, the rail 12 and the like.

(About the bucket rotating mechanism) Beside the discharge points 15a to 15f in the discharge station 14, as shown in FIG. A bucket rotating mechanism 50 as a discharging means for rotating is provided. The bucket rotating mechanism 50 is provided on the right side in the traveling direction of the hanger 20 with a fulcrum shaft 51 rotatably supported so as to extend horizontally on the gantry 11 and swings integrally with the fulcrum shaft 51. An operating rod 52 movably disposed and hanging downward, a connecting arm 68 slidably integrated with the fulcrum shaft 51 and extending upward, and an upper portion of the gantry 11. The hydraulic cylinder 5 having the tip of the rod 54a clevis-connected to the upper end of the connecting arm 68
And 4. When the hydraulic cylinder 54 is controlled so that the rod 54a advances, the operating rod 52 is displaced in a state in which the pressing roller 53 at the lower end thereof is separated from the bucket 36 (shown by a solid line in FIG. 7). When the fluid pressure cylinder 54 is controlled so that the rod 54a is retracted, the posture is displaced so that the pressing roller 53 is brought into contact with the outer lower surface of the right side plate 38 of the bucket 36. When the rod 54a is retracted to the rearmost end, the bucket 36 pressed by the pressing roller 53 is
The rotation about the support shaft 33 is reached until the opening 36a is directed leftward in the traveling direction (indicated by a two-dot chain line in FIG. 7). Therefore, the crop 92 received in the bucket 36 is discharged to the side of the hanger 20 from the opening 36a directed leftward due to the rotational displacement of the bucket 36 caused by the swing of the operating rod 52.

Further, as described above, since the rotation fulcrum (support shaft 33) of the bucket 36 is set at a position deviated leftward from the position of the center of gravity of the bucket 36, it is timely after the discharge of the crop 92 is completed. By controlling the hydraulic cylinder 54 so that the rod 54a moves forward, the bucket 36 returns to its original position by its own weight when the operating rod 52 separates from the bucket 36. The bucket 36
Is set so that the center of gravity does not move to the left side of the rotation fulcrum even when it is rotationally displaced to the maximum by the swing of the operating rod 52 (the state shown by the two-dot chain line in FIG. 7). It does not rotate any more.

(Regarding the hanger clamp mechanism) Each discharge point 15a to 15 at the discharge station 14
In FIG. 3F, as shown in FIGS. 3, 4, and 7, clamp portions 56, 5 for holding the lower rod 29 from the side are provided on the left and right sides of the passage of the lower rod 29 of the frame 25.
6, a hanger clamp mechanism 55 is provided. Each clamp section 56 includes two hydraulic cylinders 57.
And two cylindrical guide bars 58, and a distal end of a rod 57 a of each cylinder 57 and a horizontally long pressing piece 59 fixed to a distal end of each guide bar 58. Then, in each clamp portion 56, the fluid pressure cylinder 5
When the rod 57a is controlled to retreat, the pressing piece 59 is displaced so as to be separated from the lower rod 29 (indicated by a two-dot chain line in FIG. 4), and the rod 57a moves the hydraulic cylinder 57 forward. When the control is performed, the pressing pieces 59 come into contact with the side surfaces of the lower rod 29 (shown by solid lines in FIG. 4).

The hanger clamp mechanism 55 having the above-described structure is configured such that the bucket rotating mechanism 50
When the is rotated, the lower rod 29 is sandwiched from both left and right sides to prevent swinging of the hanger 20 itself, thereby functioning to allow the crop 92 to be reliably discharged. In addition, the hanger 20 is configured such that the bucket 3 does not receive the crop 92 in the bucket 36, and the bucket 3
6, when the crop 92 is received,
4, the position of the center of gravity of the entire hanger 20 is displaced due to the variation in the loading position, and as shown by the dashed line and the two-dot chain line in FIG. It often moves along the rail 12. However, even if the hanger 20 is tilted,
When the discharge points 15a to 15f are reached, the lower rod 29 is pressed by the pressing members 5 by simultaneously operating the two clamp portions 56, 56 of the hanger clamp mechanism 55.
As a result, the bucket can be returned to its original position by being pressed by 9, 59, so that the bucket rotating mechanism 50 can perform normal rotating and discharging operations. Note that, depending on the loading position of the crop 92 received in the bucket 36, as shown by the two-dot chain line in FIG. However, since the lower end surface of the lower rod 29 is formed in an arc shape, a suitable pressing by the pressing pieces 59 of the hanger clamp mechanism 55 is performed.

Below the discharge station 14, three recovery buckets 60, 61 and 62 are provided as described above and as shown in FIGS. 1, 2 and 8. That is, three rows of rails 63, 64, 65 are laid between the lower part of the discharge station 14 and the rear end of the lager wheel 67 stopped at the working position.
Carts 66 that can reciprocate while placing the collection buckets 60, 61, and 62 are disposed on the reference numerals 4 and 65, respectively.
Then, the collection bucket 60 placed on the carriage 66 on the rail 63 on the left side in the drawing can receive the crop 92 discharged at the discharge points 15c and 15d in the discharge station 14. Also, a crop collection bucket 61 mounted on a carriage 66 on a rail 64 at the center of the drawing.
Is the discharge point 15b at the discharge station 14
And the crop 92 released at 15e can be received, and the bogie 66 on the rail 65 on the right side in the drawing can be received.
Can receive the crop 92 discharged at the discharge points 15a and 15f. Therefore, for example, the rolling line 70
In the above, the crop 92 of a different material generated when rolling the material to be rolled 90 having a different material can be discharged separately to any one of the collecting buckets 60, 61, and 62 for each material. Become. The suspension-type transfer device 10 of this embodiment is controlled collectively by a host computer that comprehensively controls the rolling line 70.

[0021]

Next, the operation of the suspension type transport apparatus according to the embodiment of the present invention configured as described above will be described.

In the rolling section (not shown) of the rolling line 70, the material to be rolled 9 which has completed a predetermined rolling process
No. 0 is conveyed to the cutting section 72 on the downstream side, and stops with its front end abutting on a stopper (not shown) provided on the downstream side of the fixed hot saw 73. Then, in the cutting section 72, after the moving hot saw 77 is moved to adjust the distance to the fixed hot saw 73, the front end and the rear end of the material to be rolled 90 are cut by the hot saws 73 and 77. The product 91 adjusted to a predetermined length by the cutting process in the cutting session 70 moves on the transport conveyor 71 and is transported to the downstream side. On the other hand, the crop 92 formed by the cutting process using the fixed hot saw 73 and the moving hot saw 77 falls downward when the bottom plate of the conveyor 71 is opened,

As described above, according to the suspension type transport apparatus of the present invention, a plurality of transport bodies for transporting articles to be transported can be freely moved on the rail extending between the receiving position and the discharging position. For example, if it is installed as a conveying device for crops generated in a rolling line, it is assumed that a plurality of collection buckets are installed at the discharge position, and the crop receiving process, the transporting process, and the divided discharging process are performed. Etc. can be automatically performed, and the crop sorting operation can be rationalized and labor saved.

Further, according to the suspension type transport apparatus of the present invention, the bucket is rotatably disposed with the opening always directed upward with respect to the frame suspended and supported by the rail. After the transported articles loaded on the bucket at the position are conveyed to the discharge position, the articles can be released simply by rotating the bucket. If, for example, a hanging conveyor is used as a sorting and collecting device for crops formed in a rolling line, the crop receiving process, the conveying process, and the sorting discharge are performed on the assumption that a plurality of collecting buckets are installed at the discharge position. Since all the steps and the like can be performed automatically, there is an advantage that the operation of sorting the crop can be rationalized and labor can be saved. Furthermore, if the discharge position of the crop where the collection bucket is installed is set close to the position where the lager truck that collects the collection bucket approaches, the overhead traveling crane where the transfer operation of the collection bucket is installed in the factory is performed. It has the advantage that it can be performed without any use and does not affect the work in the factory.
