Description

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 left after a defective off-gauge portion at a leading end and a trailing end of a plate material such as a steel plate is cut by a shear to a recovery destination.

[0002]

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

As this processing device, for example, the actual development 5
9-90523 and Japanese Utility Model Laid-Open No. 4-86114.

The former is a double-door type in which an elevator for receiving crops is provided on a trolley, and the bottom plate of this elevator is opened and closed by a cylinder device. Then, in the work, the crops discharged from the shear are received and stored by the lift table, and when the fixed amount is reached, the cart is moved to just above the discharge pit, and then the bottom plate is opened to discharge the crops.

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

In the former crop processing apparatus, each of the former requires a drive system and a control system for the lifting operation of the lifting platform, the traveling of the carriage, and the opening / closing operation of the bottom plate, and the configuration of the apparatus is considerably complicated. .

On the other hand, in the latter case, the tilting operation of the bucket is achieved by simply linking a simple link mechanism connected to the bucket to the cylinder device on the work floor side.
The overall device configuration becomes 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 depending on the incident angle of the crops and the like.

For example, in the former case, it is impossible to store the crops neatly unless the lifting operation of the lifting platform is optimized. For this reason, it is often the case that the crops cannot be quickly sent from the lifting platform to the discharge pit.

The same applies to the latter case, and it is necessary to increase the capacity of the bucket in advance in order to receive the crop from the shear. Further, 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 improvement in downsizing of equipment can be suppressed.

As described above, the conventional crop processing equipment cannot properly receive and store the crop from the shear in the bucket, and the equipment is not sufficiently simplified and compacted.

The problem to be solved in the present invention is to enable the crops to be housed in a bucket in an orderly manner and to be conveyed and collected to the discharge pit side with simple equipment by a single drive system.

[0013]

DISCLOSURE OF THE INVENTION The present invention is a processing apparatus provided with a bucket for receiving and storing crops discharged from a shear, and a carriage for supporting the bucket and moving from the shear to a discharge destination of the crops. A container having a substantially L-shaped vertical cross section with an open side facing the discharge surface of the crop from the shear is arranged inside the bucket, and the container is provided with a discharge level of the crop from the shear. It is characterized in that it is on the lower side and can be shifted to an inclined posture in which the shear side is raised.

Further, the bucket is connected to the carriage so as to be vertically tiltable toward the surface facing the discharge destination, and is closer to the discharge destination than the contact point between the bucket and the carriage. It is also possible to arrange a receiving block that is engageable and disengageable with the bucket on the lower side and on the discharge destination side.

Further, even for a trolley having a container in the bucket, the bucket is connected to the trolley so that the bucket can be vertically tilted toward the surface facing the discharge destination, and is engaged / disengaged with the bucket. Possible receiving blocks may be arranged.

[0016]

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

When the dolly is moved to the discharge destination,
While the bucket precedes the receiving block and its movement is restricted, the dolly still moves to the discharge destination, so the bucket rotates so that its rear end side is lifted and its front end side is oriented downward. Change. Therefore,
As long as a drive system for moving the carriage is provided, the bucket can be reversed at the discharge destination, and movement and discharge can be continuously operated by one drive system.

Furthermore, if the equipment provided with the preceding container and the receiving block is used, it becomes possible to align and collect the crops from the shear to the container and to discharge the crops to the discharge destination linked to the movement of the carriage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view showing the outline of a crop processing apparatus of the present invention, and FIG. 2 is a schematic view seen in the direction of arrow AA in FIG.

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

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 that travels these rails 2a and 2b. An electric motor 2c is provided at the upper end of the rail 2a, and a chain 2d connected to the output shaft of the rail 2a is connected to the carriage 3 to drive the carriage 3 between the shear 50 and the discharge pit 51.

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

The trolley 3 is provided with a total of four wheels 3a rolling on the rails 2a and 2b, and a pair of brackets 3b are provided on the upper surface thereof so as to be obliquely upward in the traveling direction when moving to the discharge pit 51 side. ing. These brackets 3b are
One end side of the bucket 4 is pivotally supported by pin joining, and the other end side of the bucket 4 is swingably supported in the vertical direction. Further, 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 the crop is received from the shear 50, the bucket 4 takes a horizontal posture as shown in FIG. 1, and when it goes to the discharge pit 51, the rails 2a and 2b.
A mechanism capable of changing the posture by a cylinder device or the like should be provided so as to be parallel to.

The bucket 4 is a container having an open upper surface and a surface facing the discharge pit 51 side. As shown in FIG.
On the side facing the discharge pit 51, a pair of arms 4b are projected obliquely downward, and rollers 4c are rotatably attached to the respective tips. As shown in FIGS. 2 and 3, rollers 4e are provided at both ends of the bucket 4 in the width direction, and the guide rails 4f in which the rollers 4e are horizontally arranged are provided.
It can be rolled up.

Further, inside the bucket 4, there is a shear 50.
A container 5 is provided for receiving a large number of crops from and holding them without any row of large disturbances. As shown in FIG. 3, the container 5 includes a mounting plate 5a and a receiving plate 5b each having a L-shaped vertical cross section when viewed in the moving direction of the carriage 3, and the carriage 3 is provided near the shear 50. When moved, the surface facing the shear 50 is opened so that the crop can be received.

The container 5 is pivotally attached to the connecting block 4d on the upper surface of the bucket 4, and can be rocked in the direction of the arrow in FIG. 3 by the operation of the cylinder 6 connected between the two.

On the other hand, on the upper ends of the rails 2a and 2b, as shown in FIG. 2, a receiving block 7 for receiving the roller 4c provided on the arm 4b of the bucket 4 and changing the posture of the bucket 4 in the upside-down direction. To provide. This receiving block 7 has a substantially J-shape with the top and bottom reversed,
When the trolley 3 moves to the discharge pit 51 side and the roller 4c enters and stops, and then the trolley 3 further advances, the movement of the bucket 4 is blocked, and the tip side of the bucket 4 is directed downward around the roller 4c. It has the function to incline it so that.

Further, since the crop from the shear 50 is sent to the processing apparatus 1, as shown in FIG.
A chute 53 for the roller row that guides is provided. The chute 53 is provided so as to be in a position facing the posture in which the container 5 is drawn out from the bucket 4 by the cylinder 6 from above.

In the above structure, in order to collect the crops 52 intermittently sent from the chute 53, the carriage 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 placed on the guide rail 4f, and the bucket 4 is maintained in a horizontal posture. Then, the cylinder 6 is operated to tilt 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 discharge 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 also hits the receiving plate 5b and is stacked on the placing plate 5a. In this way, the crop 52 receives the receiving plate 5b.
Since they are stacked against each other, they can be aligned with at least one side of the crop 52, that is, the contact surface with the receiving plate 5b. Therefore, even if the sizes of the crops 52 are different, it is possible to store the crops while suppressing the disorder of the stacked state.

Then, after the container 5 receives a certain amount of crops 52, the container 5 is rotated clockwise by the cylinder 6 in FIG. Then, the electric motor 2c is operated to activate the chain 2
The trolley 3 is moved toward the discharge pit 51 side 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. As a result, the bucket 4 is prevented from moving to the discharge pit 51, and the carriage 3 is only pivotally attached to the bucket 4 by the bracket 3b. Therefore, only the carriage 3 can move further to the discharge pit 51 side. The level of the trolley 3 continues to rise. Therefore, in FIG.
To (d), the roller 4c has a receiving block 7
As the bucket 4 itself is pushed upward by the cart 3, the tip of the bucket 4 gradually tilts downward as shown in FIG.

As described above, the carriage 3 can be moved toward the discharge pit 51 side, and the attitude of the bucket 4 can be changed to the upside-down direction near the end point in the conveying direction. Therefore, when the trolley 3 reaches the final position, the inclination angle at which the tip of the bucket 4 faces downward becomes large, and the crops 52 accommodated therein can be sequentially sent to the discharge pit 51.

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 shown in FIG. At this time, the roller 4c gradually begins to descend in the receiving block 7 and is finally disengaged so that the bucket 4 is placed on the carriage 3 substantially in parallel, and finally the sheer 50 from the shear 50 in FIG. The receiving posture of the crop 52 is set.

As described above, by allowing the container 5 to be tilted and receiving the crop 52 from the shear 50 by the receiving plate 5b, it is possible to collect a large number of crops 52 with little disturbance in the stacking direction. Therefore, when it is sent to the discharge pit 51 due to the inclination of the bucket 4,
The crop 52 moves smoothly and smoothly, and a quick disposal process is realized.

Further, since the carriage 3 can be moved from the shear 50 side to the discharge pit 51 and the bucket 4 can be turned upside down only by driving with the electric motor 2c, a large number of drive systems and control systems as in the prior art. Efficient work can be performed with simple equipment without the provision of.

In the illustrated example, the container 5 is incorporated in the bucket 4 and the tilting operation is used to suppress the disorder of the stack of crops 52. However, the bucket 5 is not provided with the container 5. A method in which the crop 52 is directly put in may be used. Even in this case, the bucket 4 can be reversed by moving the trolley 3 to the discharge pit 51 side, and the trolley 3 is moved to the discharge pit 51 of the crop 52 by a single drive system as in the previous example. Can be dumped.

[0039]

According to the present invention, since a single drive system can be used for traveling between the shear side and the discharge side of the carriage and for discharging the crop to the discharge side, the drive system and The control system is simplified and the equipment is simplified.

By incorporating a container capable of tilting operation into the bucket, at least one side of the crop from the shear can be aligned in the stacking direction and housed in the bucket. Considering the disturbance of the input crop as in the conventional case. The bucket does not have to have a large capacity. Therefore, the facility area can be downsized and the line can be shortened, and at the same time, the automated operation can be performed.
