JPH10315193A - Cutting work support device for band saw cutter - Google Patents

Abstract

PROBLEM TO BE SOLVED: To hold a work in a standing-up and arranged condition, and easily take it out in a post-process by arranging a screen plate in the pushing-out direction of the work, and movably supporting a short size work in the pushing- out direction while keeping a constant interval. SOLUTION: A cutting object 2 is pushed out up to a cutting position while automatically measuring a length by a pushing-out device 5. At this time, the first work 2A gradually approaches a screen plate 7, but when a sensor 9 detects a constant interval (t), a driving device 10 is driven through a control device 11, and the screen plate 7 retreats so as to keep the interval (t). When positioning finishes, the cutting object 2 is cut by a band saw cutter 4. Afterwards, actuation of the screen plate 7 is repeated again. When a cutting process of running over the total length of the cutting object 2 finishes, the work 2A is put in a condition of standing up on a receiving conveyor 6 or a standing-up condition of keeping a prescribed inclination. Therefore, when cutting work finishes, carrying-out of works 2A... can be handles in a standing-up and arranged collective condition, and carrying out work can be quickly performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting work support device for a band saw cutting device, and more particularly to a method for automatically and continuously cutting a short work from a long material. To a device that prevents

[0002]

2. Description of the Related Art Conventionally, when a long material such as a casting die is cut into a short length to form a workpiece, a band saw cutting device may be used as shown in FIG.

The band saw cutting device 1 is an extruder that extrudes a band saw cutting machine 4 at one end of a conveyor 3 for receiving an object 2 and extrudes the object 2 at the other end of the conveyor 3 while automatically measuring the length. 5, the object 2 is cut, and after the object 2 is pushed out to a new cutting position, the work 2A is discharged onto the conveyor 6 using the pushing force at that time.

[0004]

However, when the work 2A is short, it is easy to fall down during extrusion as shown in the figure, and when it falls down, it takes time and effort to take out the work 2A. In the case of (1), there is a drawback that the work efficiency is extremely deteriorated because the removal has to rely on the mechanical force of a crane, a winch or the like.

[0005] Therefore, when cutting a small-sized work that is easy to fall down, it is necessary to carry out the work manually each time it is cut, and thus there is a problem that work efficiency cannot be improved and danger is involved. there were.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problem. When a short work is cut from a long cut object, the cut work is aligned without falling down. An object of the present invention is to provide a cutting work supporting device of a band saw cutting machine that can hold and carry out a mechanical and safe operation at a stroke.

[0007]

A cutting work supporting device of a band saw cutting machine according to the present invention cuts a long object to be cut into a short length with a band saw cutting machine, and extrudes the short work with the object. At the same time, in a band saw cutting device that positions the object to be cut at a cutting position of a band saw cutting machine, a partition plate is provided in a direction in which the work is pushed out, and the partition plate is capable of reciprocating in the pushing direction. The base frame is provided with a sensor for detecting an interval between the partition plate and the work, and the base frame is a driving device that moves so that the interval detected by the sensor is always constant. A control device is provided.

That is, since the short work is supported by the partition plate moving in the extrusion direction while maintaining a constant interval, the work does not fall. Therefore, even if the workpieces are sequentially extruded with the pushing force, the workpieces are kept in an upright and aligned state, and the workpieces can be easily taken out for shifting to a subsequent process.

[0009]

Next, an embodiment of the present invention will be described. FIG. 1 is a side view of an embodiment of the apparatus of the present invention, FIG. 2 is a plan view of the same, FIG.
FIG. 4 is a side view showing an operating state.

A long workpiece 2 such as a casting material is cut into a short length by a band saw cutter 4, and the short work 2 A is extruded by an extruder 5.
In the band saw cutting device 1, which simultaneously pushes the workpiece 2 onto the receiving conveyor 6 with the workpiece 2 extruded by the cutter and positions the workpiece 2 at the cutting position of the band saw cutter 4 in the direction in which the workpiece 2 </ b> A is extruded. , A partition plate 7 is provided, and the partition plate 7 is supported by a base frame 8 which can reciprocate in the pushing direction. The base frame 8 has a sensor 9 for detecting an interval between the partition plate 7 and the work 2A. The base frame 8 is provided with a driving device 10 and a control device 11 for moving the interval t detected by the sensor 9 so as to be always constant.

In the above, the base frame 8 supporting the partition plate 7
Is provided on a cart 8A, and a drive device 10 is provided on the cart 8A. In addition, although the case where the cart 8A is used is shown as a configuration for moving the base frame 8, a guide rail and a slider (not shown) sliding on the guide rail are used.
It is good.

In the above description, the interval t is such that the horizontal distance d at the height h from the lower end is constant as shown in FIG. 3, and the horizontal distance d is such that the inclination angle α is maintained even when the work 2A leans. Angles greater than 60 °, preferably α =
The interval is in the range of 75 ° to 80 °.

When α <60 °, the inclined work 2A
And the work efficiency when unloading the work 2A cannot be improved.
In the case of ≒ 90 °, when the work is extruded, the screen plate 7 is forcibly pushed unless synchronized with the operation of the driving device 10, which may cause a failure of the driving device 10, the base frame 8, and the cart 8 </ b> A. Because there is.

In FIG. 2, reference numeral 12 denotes a pusher for receiving the workpieces 2A... 2A after the completion of the cutting process and discharging the workpieces 2A to the side of the conveyor 6. Next, the operation of the above device will be described.

The workpiece 2 is extruded to the cutting position while automatically measuring the length by the extruder 5. This is the first work 2
A gradually approaches the partition 7, but a certain interval t is detected by the sensor 9.
Is detected, the driving device 10 is driven via the control device 11, and the partition plate 7 moves backward so as to keep the interval t.

When the positioning is completed, the workpiece 2 is cut by the band saw cutting machine 4. Thereafter, the operation of the partition plate 7 is repeated again. In this process, even if the work 2A falls down, the work 2A does not fall down completely and lie flat only by leaning on the partition plate 7.

When the cutting process is completed over the entire length of the workpiece 2, the work 2A is in an upright state on the receiving conveyor 6 or in an upright state in which the inclination angle α is maintained.

Accordingly, the workpieces 2A... 2A at the end of the cutting operation
Can be handled in a state of standing and aligned, and the unloading work can be performed quickly. After unloading the cut work group from the receiving conveyor 6,
The pressing member 7 is pulled back to the start end 6A side by the driving device 8 and prepares for the next cutting step.

[0019]

As described above, according to the present invention, when a short workpiece is automatically cut continuously from a long workpiece,
The work is supported by the holding member on the receiving conveyor and does not fall over, so that the work after cutting can be uniformly handled and the work efficiency is improved.
