DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crop processing apparatus for transporting a crop remaining after cutting a defective portion of an off-gauge at a leading end and a trailing end of a plate material such as a steel plate with a shear to a collecting destination.

[0002]

2. Description of the Related Art In a steel sheet manufacturing facility, there is a step of cutting off the off-gauge portion of the manufactured steel sheet with a shear, and a cut piece (hereinafter referred to as "crop") generated at this time is processed near a shear. Is provided with a processing device.

[0003] As this processing apparatus, for example,
There are those described in JP-A-9-90523 and JP-A-4-86114.

[0004] In the former, a lifting platform for receiving crops is provided on a carriage, and the bottom plate of the lifting platform is of a double-open type which is opened and closed by a cylinder device. Then, in the operation, the crop discharged from the shear is received and stored on the elevating platform, and when a certain amount is reached, the bogie is run right above the discharge pit, and then the bottom plate is opened to discharge the crop.

In the latter, a bucket for receiving a crop is placed on a bogie and a link is connected to the bucket, and a cylinder device arranged on a work floor side such that a discharge end side of the crop is inclined downward is interlocked with the link. It was made possible.

In such a crop processing apparatus, the former requires a drive system and a control system for the elevating operation of the elevating platform, the traveling of the trolley, and the opening and closing operation of the bottom plate, and the configuration of the apparatus is considerably complicated. .

On the other hand, in the case of the latter, the tilting operation of the bucket only requires the simple link mechanism connected to the bucket to be linked to the cylinder device on the work floor side.
The overall arrangement is relatively simple.

[0008]

However, in any of the examples, when a large number of crops are received from the shear, they cannot be stored neatly due to the angle of incidence of the crops.

For example, in the former case, it is impossible to store the crops neatly unless the elevating operation of the elevating platform is optimized. For this reason, it is often not possible to quickly send the crop from the lift to the discharge pit.

The same applies to the latter case. In order to receive a crop from the shear, it is necessary to increase the capacity of the bucket in advance. In addition, from the viewpoint of the drive system, a drive mechanism for moving the carriage and a cylinder device for operating the link mechanism are required, and the improvement in the compactness of the equipment can be suppressed.

As described above, in the conventional crop processing equipment, the crop from the shear cannot be received and stored in the bucket in an orderly manner, and the simplification and compactness of the equipment have not been sufficiently achieved.

The problem to be solved in the present invention is to enable crops to be stored neatly in a bucket and to be conveyed and collected to the discharge pit by simple equipment with a single drive system.

[0013]

According to the present invention, there is provided a processing apparatus comprising: a bucket for receiving and storing a crop discharged from a shear; and a bogie supporting the bucket and moving from the shear to a destination of the crop. And on the trolley

[0016]

[Function] The crop from the shear is thrown into the container due to the level difference. At this time, if the container having the L-shaped vertical cross section is set to the inclined position where the shear side is higher,
The crop is constrained by two surfaces: a mounting surface of the container and a receiving surface against which the tip of the crop abuts. Therefore, it is possible to stack the crops on the placement surface in such a manner that one side, which is the tip of the crop and collides with the receiving surface, is aligned at least so as to follow the receiving surface.

When the truck is moved to the discharge destination,
While the bucket engages with the receiving block in advance and is restrained from moving, the bogie still moves to the discharge destination, so the bucket rotates so that its rear end is lifted and its posture is such that its front end is downward. Change. Therefore,
If only a drive system for moving the carriage is provided, the bucket can be inverted at the discharge destination, and the movement and discharge can be continuously operated by one drive system.

Further, if the equipment is provided with the above-mentioned container and receiving block, it is possible to arrange and collect the crops from the shear to the containers and discharge the crops to the discharge destination in conjunction with the movement of the cart.

[0019]

FIG. 1 is a plan view showing the outline of a crop processing apparatus according to the present invention, and FIG. 2 is a schematic view seen in the direction of arrows AA in FIG.

In FIG. 1, a processing apparatus 1 is laid out between a shear 50 and a discharge pit 51 for collecting crops so as to be orthogonal to the flow direction of the line.

The processing apparatus 1 is provided with two rails 2a and 2b diagonally upward from the shear 50 toward the discharge pit 51, and a carriage 3 running on these rails 2a and 2b is provided. An electric motor 2c is provided at the upper end of the rail 2a, and a chain 2d connected to an output shaft of the electric motor 2c is connected to the truck 3, so that the truck 3 is driven to travel between the shear 50 and the discharge pit 51.

The cart 3 has a built-in bucket 4 for receiving a crop from the shear 50, and the details thereof are shown in FIGS. FIG. 3 corresponds to the direction of arrow BB in FIG. 1, and FIG. 4 corresponds to the right side view of FIG.

The truck 3 has a total of four wheels 3a that roll on the rails 2a and 2b. A pair of brackets 3b are provided on the upper surface of the truck 3 obliquely upward in the traveling direction when moving to the discharge pit 51 side. ing. These brackets 3b are
One end of the bucket 4 is pivotally supported by pin bonding, and the other end of the bucket 4 is supported so as to be able to swing vertically. Stopper blocks 3c and 4a are provided between the upper surface of the carriage 3 and the lower surface of the bucket 4 so that the bucket 4 is held in a horizontal posture as shown in FIG.

When receiving a crop from the shear 50, the bucket 4 takes a horizontal position as shown in FIG.
A mechanism capable of changing the posture by a cylinder device or the like is provided so as to be parallel to.

The bucket 4 is in the form of a container having an open top surface and a surface facing the discharge pit 51, as shown in FIG.
A pair of arms 4b project diagonally downward from the side facing the discharge pit 51, and rollers 4c are rotatably attached to the respective ends. As shown in FIGS. 2 and 3, rollers 4e are provided at both ends in the width direction of the bucket 4, and guide rollers 4f on which the rollers 4e are horizontally arranged.
Rollable above.

Also, a shear 50 is provided inside the bucket 4.
A container 5 is provided for receiving a large number of crops from the container and holding them without forming a large turbulent row. As shown in FIG. 3, the container 5 includes a mounting plate 5 a and a receiving plate 5 b having an L-shaped vertical cross section as viewed in the moving direction of the cart 3. When moved, the surface facing the shear 50 side is opened so that the crop can be received.

The container 5 is pivotally mounted on a connection block 4d on the upper surface of the bucket 4, and can be swung in the direction of the arrow in FIG. 3 by the operation of a cylinder 6 connected between the two.

On the other hand, on the upper end side of the rails 2a and 2b, as shown in FIG. 2, a receiving block 7 for receiving a roller 4c provided on an arm 4b of the bucket 4 and changing the attitude of the bucket 4 in the upside down direction. Is provided. This receiving block 7 has a substantially J-shaped shape with the upside down,
When the carriage 3 moves toward the discharge pit 51 and the rollers 4c enter and stop, and the carriage 3 further moves forward, the bucket 4 is prevented from moving and the tip side of the bucket 4 faces downward around the rollers 4c. It has a function to tilt it so that

Further, in order to send the crop from the shear 50 to the processing apparatus 1, as shown in FIG.
Are provided. The chute 53 is provided at a position facing the posture in which the container 5 is fed upward from the bucket 4 by the cylinder 6.

In the above arrangement, the truck 3 is first stopped and positioned at a position corresponding to the shear 50 as shown in FIG. At this time, as shown in FIG. 2, the roller 4e of the bucket 4 is mounted on the guide rail 4f, and the bucket 4 is maintained in a horizontal posture. Thereafter, the cylinder 6 is operated to incline the container 5 as shown in FIG.
Is set to a posture substantially matching the inclination angle of the chute 53. As a result, the receiving plate 5b is held in a posture orthogonal to or close to the release trajectory of the crop 52 from the chute 53.

The tip of the crop 52 from the chute 53 collides with the receiving plate 5b, and the succeeding crop 52 similarly hits the receiving plate 5b and is stacked on the mounting plate 5a. In this manner, the crop 52 receives the receiving plate 5b.
, So that at least one side of the crop 52, that is, the abutting surface with the receiving plate 5b, can be aligned. Therefore, even if the sizes of the crops 52 are different, it is possible to store the crops 52 while suppressing the disorder of the stacked state.

Next, after a certain amount of the crop 52 has been received by the container 5, the container 6 is rotated clockwise in FIG. Then, the electric motor 2c is operated to drive the chain 2
The carriage 3 is moved in a direction to lift the carriage 3 toward the discharge pit 51 via d.

As the carriage 3 moves, the roller 4c provided at the tip of the arm 4b of the bucket 4 reaches the receiving block 7. Thereby, the movement of the bucket 4 to the discharge pit 51 is prevented, and the carriage 3 is only pivotally connected to the bucket 4 by the bracket 3b. Therefore, only the carriage 3 can further move to the discharge pit 51 side. The level of the trolley 3 subsequently rises. Therefore, FIG.
To (d), the roller 4c is
, And the bucket 4 itself is also pushed upward by the cart 3, so that the tip of the bucket 4 gradually tilts downward as shown in FIG.

As described above, the carriage 3 is moved toward the discharge pit 51, and the attitude of the bucket 4 can be changed in the upside down direction near the end point in the transport direction. Therefore, when the carriage 3 reaches the final position, the inclination angle at which the tip of the bucket 4 faces downward increases, and the crops 52 stored therein can be sent out to the discharge pit 51 in order.

When the discharge of the crop 52 is completed, the rotation of the output shaft of the electric motor 2c is reversed, and the carriage 3 is returned to the original position in FIG. At this time, the roller 4c starts to gradually descend in the receiving block 7 and is finally disengaged, and the bucket 4 is placed almost in parallel on the carriage 3, and finally the bucket 4 from the shear 50 in FIG. The receiving posture of the crop 52 is set.

As described above, the container 5 can be tilted and the crops 52 from the shear 50 are received by the receiving plate 5b, so that a large number of crops 52 can be collected with little disturbance in the stacking direction. Therefore, when sending out to the discharge pit 51 due to the inclination of the bucket 4,
The start and movement of the crop 52 are also smooth, and a prompt disposal process is realized.

Further, the carriage 3 can be moved from the shear 50 to the discharge pit 51 and the bucket 4 can be turned upside down only by driving the motor 2c. It is possible to carry out efficient work with simple equipment without providing the equipment.

In the illustrated example, the container 5 is incorporated in the bucket 4 and the turbulence of the stacked body of the crop 52 is suppressed by utilizing the tilting operation. Alternatively, a method in which the crop 52 is directly put into the camera may be used. Also in this case, the bucket 4 can be reversed by moving the carriage 3 to the discharge pit 51 side, and the carriage 3 moves to the discharge pit 51 of the crop 52 by a single drive system as in the previous example. And dumping.

[0039]

According to the present invention, the traveling between the shear side and the discharge side of the bogie and the operation of discharging the crop to the discharge side can be performed by a single drive system. The control system is simplified and the equipment is simplified.

By incorporating a tiltable container into the bucket, at least one side of the crop from the shear can be arranged in the stacking direction and stored in the bucket. There is no need to make the bucket a large capacity. Therefore, the equipment area can be reduced in size and the line can be shortened, and at the same time, automatic operation can be performed.
