Abstract

PURPOSE:To smoothly perform steel billet carriage by installing a sensor for steel billet carrying-in detection and putting a shuttle car on a carriage frame extending between the preceding and the succeeding transfer device. CONSTITUTION:A steel billet carrying path 24 is divided into the preceding and succeeding transfer device parts 11A and 11B on respective sides of a roller conveyer 25. A mechanical sensor 35 is installed in the position of the conveyer 25 shown by the arrow (a). A shuttle car is put, through wheels, on a carriage frame 48 installed to extend between the preceding and succeeding parts 11A and 11B of the transfer device. When the sensor 35 detects a steel billet 2C carried on the transfer device part 11A, the frame 48 moves up and the sensor 35 moves down by action of a cylinder. Then, the shuttle car moves the steel billet 2C beyond the conveyer 25 to transfer the billet 2C onto the transfer device part 11B. In that method, the steel billet carriage is smoothly performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a transfer mechanism in a billet transfer device.

(Prior technology) Steel slabs obtained by continuous casting have defects on the inside and outside of the steel slab due to slag mixed in during casting, etc. Conventionally, the steel slabs were passed through a magnetic flaw detector to mark the discovered flaws. This is used as a mark 1 and the scratches are removed with a cutter.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional method relies on manual labor, it has the drawback of being inferior in ability to remove defects from steel slabs.

Therefore, the inventor of the present invention, "5, came up with an automated steel billet eaves removal equipment as shown in the embodiment configuration described later (in particular, FIG. 1). From the stand to flaw detection equipment → Sorting equipment → Eaves removal equipment → Transfer equipment →
During this process, the individual pieces of steel are
By registering the registered registration number and the location and size of the flaw detected by the flaw detection device, the flaw removal device is activated based on this data to automatically remove flaws from the steel billet brought into the device. This enables batch automation of flaw detection and flaw removal.

By the way, in this facility, it is necessary to use a plurality of flaw removal devices to process a large number of steel pieces, and the steel pieces coming out from each of these flaw removal devices are collected and sent to a collection table by a transfer device. . To do this, the pieces of steel that are randomly sent to the transfer device must be transported in an orderly manner in the same direction without interfering with each other.

An object of the present invention is to provide a transfer device in a billet transfer device for this purpose.

(Steps to Solve the Problems) The present invention is for carrying steel billets into a billet transcribing device from a direction perpendicular to the direction of the billet conveying force.
The above-mentioned roller conveyor for carrying in steel billets is installed between the front-stage transfer device part and the rear-stage transfer device part that sandwich the steel billet carry-in path, and between the conveyor rollers, the conveyor roller is always at the level of the first surface of the conveyor roller. A mechanical sensor for detecting the introduction of steel pieces that protrudes from the front and back is provided, and a transfer frame is installed at a lower position spanning the front and rear transfer device parts, and a shuttle car is mounted on the transfer frame. The front stage transfer device section is configured to raise the transfer frame and lower the mechanical sensor based on the detection of the transported steel piece on the bone,
- The conveyed steel piece No. 111 is lifted by a shuttle car by lifting, and is transferred to the rear stage transfer device portion by passing over the L roller conveyor by the shuttle of the shuttle car.

(Function) According to the present invention, when the steel billets are randomly conveyed from each flaw removal device to the steel billet transfer device via the roller conveyor, the steel billets in the previous stage transfer device section 1 are transferred by the shuttle car (, 11. Since the steel billet is transferred to the latter stage transfer device by climbing over the roller conveyor, it is possible to transport the steel billet in a predetermined direction in an orderly manner without being hindered by the roller conveyor for carrying in the billet.

(Example) First, referring to FIG. 1, an outline of a flaw removing equipment to which the transfer mechanism of the present invention is applied will be explained.

That is, a large number of steel billets (billet I-) (2) having a rectangular cross section manufactured by continuous casting equipment are placed on a billet loading table (+) and prepared. The steel billet (2) on this billet charging table (1)
) are sequentially sent to the conveyance path side from the delivery conveyor device (1a), and sent out one by one to the conveyance path from the billet loading table (1) by a transfer device.

The conveyance path is formed by a V roller conveyor (3), and the steel billet (2) is conveyed by forcibly rotating an appropriate number of V rollers (3a)...
2) is first carried into the stain blasting device (4),
Rust removal from the surface of the steel piece and registration of the steel piece (2)
This registration number is registered in the computer.

Next, the steel piece (2) is sent to the first flaw detection device (5),
A flaw detection operation is performed on the first and second sides of the steel piece, and if a flaw is found, the position, size, length, and depth of the flaw are registered in the computer in accordance with the registration number. Ru.

The steel piece (2) exiting the first deep flaw detection device (5) is rotated 180 degrees by the inverter (6), and then transferred to the second deep flaw detection device (
7), flaw detection is performed on the remaining two surfaces, and the position and size of the flaw is registered in the same way.

Thereafter, the steel billet (2) is carried into an ultrasonic flaw detection device (8), and the inside of the steel billet is inspected to determine whether there are any flaws.

On the exit 11 side of the ultrasonic flaw detection device (8), there is a flaw detection defect extraction table (9) and a first
Transfer equipment (lO) is installed. Then, the computer 1.Based on the flaw detection results mentioned above,
Unscrupulous steel pieces (2A) that are found to be unusable even after removing the defects due to their own flaws (1) are placed on the flaw detection defect extraction table (9).
), and steel pieces (2B) with no defects at all, and steel pieces (2C) that have been judged to be sufficiently usable with 1-11 scratches removed, are sent to the first transfer device (lO). Allocate to. The steel piece (
Of course, two people) will be used for recasting.

In the first transfer device (10), the steel billet (2B) (2
G) is transported in rows 11a in a lateral direction perpendicular to the previous transport direction, and is received by the receiver 11-inverter (10a). Of these, all (free steel pieces (2B)
The conveyance is interrupted by the reversing operation of , and reaches the end of the first transfer device (10), from where it is directly conveyed to the second transfer gamma device (11), which will be described later.

On the other hand, the flawed steel piece (2C) is
), the next stage distribution is sent to the device (12). This sorting device (Seal 2) is a reversing device (13a)
(14a) (15a) Scratch removing device (+3) (1
4HI5) is used to feed the steel billet (2), but the flaw removing device is 3 as shown in the figure to remove the steel plate.
A device (I2) is equipped with a transfer device (this may be two or three or more), and the device (I2) is a steel billet (2C) received from the first transfer device (10). The robot selects an available defect removal device and sends it to the device according to instructions from the computer. For example, according to the figure, the first
A steel piece (2C) is being fed toward the flaw removing device (13), the second flaw removing device (I4) has just started flaw removal, and the third flaw removing device (15) is Defect removal work is halfway underway. However, each piece of steel (2
Assuming that the number and size of defects in C) are approximately the same, the third defect removal device (
15), the sorting device (12) moves to transfer the next piece of steel toward the third flaw removing device (15). However, in reality, each steel billet (2C) has a different number of flaws, a different size, etc., so the work time for each flaw removal device is estimated and added each time the next steel billet is fed. , if any of the flaw removing devices (13) (+4) (15) is vacant, it is desirable to select, for example, the second flaw removing device (14) and send the work to this preferentially.

Each flaw removing device (13), (14), and (15) uses information stored in the computer based on the registered amount -j of the incoming steel billet (2C) to apply the flaw removing pressure to the flawed part. It will be done. This processing is performed by the reversing device (13a) (4a
) (15a) is applied to the flawed face plate of the four sides of the steel piece (2C). Thereafter, the steel billet (2C) is sent to the second transfer device (It) of the present invention that moves in the same direction as the first transfer device (10), and the above-mentioned defect-free material that has been sent on a separate line is sent to The steel piece (2B) is transported to the +IF inspection section (16).

+JF Inspection Department (IB) has workers inspect each steel piece (2B) (2C) one by one using 11-sight inspection, and determines whether any defects remain despite the above-mentioned defect removal process or those with no defects. Select items that actually have defects despite being judged.

Among the steel materials that have passed through the +1 inspection section (16), the steel pieces that are determined to be defective pass in front of the collection table (17), reach the 11)' detection table (18), and are transferred there. . - On the other hand, the steel pieces determined to be good are transferred to the stacking table (+7) and are sorted there. In Figure 1, (19)
(20) has a small stopper for stopping defective products and non-defective products at the front of the +11 detection table (18) and collection table (17), respectively, and (21122) has made these stoppers 1, The transfer claw of the transfer device is shown.

Next, the second transfer device (11) according to the present invention will be explained with reference to FIG. 2 and the following drawings.

The second transfer device (II) is each flaw removing device (13)
- (15), but for the sake of simplicity in Figure 2, the part with the flaw removing device (13) and the steel billet entrance paths (23) and (24) from (+4) is shown. Boss. Each of the billet loading paths (23) and (24) is constituted by a roller conveyor (25), and as shown in the part side of Fig. 2, a motor (
26) is transferred to the sprocket (27) and Cheno (
28) to each conveyor roller (29)..., thereby carrying the steel piece (2C) placed thereon into the second transfer device (I1).

The second billet loading path (24) is connected to the roller conveyor (25).
) into a former transfer device portion (IIA) and a subsequent transfer device portion (1111+)).

Each part (IIA) (I1 port) is a conveyor frame (3θ
) ) ir: Bi, j, sprocket 7 placed on both ends
The chains (31, 32) are interlocked to form a chain conveyor, which is driven by the rotational force of a motor (33) being manually applied via a shaft (34). In this case, as is clear from the figure, in order to achieve rotational synchronization, rotational force is inputted to the front-stage transfer device section (IIA) and the rear-stage transfer device section (JIB) from the same shaft (34).

As shown in Fig. 3, the level at which the steel billet is carried in by the roller conveyor (25) is set to be slightly -L from the conveying surface of the second transfer gamma device (II), and a mechanical sensor is installed at the part indicated by arrow A in Fig. 2. (35) is equipped.

This mechanical sensor (35) is a striker with a roller that rotates around a horizontal fulcrum (36) as shown in Figure 4.
(37), and the roller striker (37) is moved by the balance weight (38) to the roller conveyor (2).
5) The incoming steel piece (2C) is always biased to protrude in the t direction, and therefore slides on the roller conveyor (25).
hits the roller striker (37) and rotates it downward. This rotation causes the drive of the arm (39) connected to the horizontal fulcrum (36),
This kicks the proximity sensor (40) and takes out the steel piece No. 411. On the other hand, a pair of rotating shafts (41) (41) are installed on both sides of the do portion of the mechanical sensor (35), and each is supported by a support frame (42). The mechanical sensor (35) is mounted on a support frame (43), and this support frame (43) is connected to the rotating shafts (41) on both sides.
) is supported by a lever (44) via a pin (45).

In addition, the 1-arrangement rotating shaft (41) has a lever (
4B), a transfer frame (48) is supported via a pin (47). The transfer frame (48) is disposed above the front and rear transfer device sections (IIA) and (IIB), and is provided at each position indicated by the arrow in FIG. 2. In other words, the conveyor frame (30) (
30) Located between. Transfer frame (48) 1
- The rail is a rail (49), on which the shuttle car (50) that runs is mounted via i (wheels (51)). In the cylinder, the shuttle car (50) runs between the front transfer device section (IIA) and the rear transfer device section (IIB).

+) If the pair of co-rotating shafts (41) (41) are rotated in the same direction by driving the cylinder (53) in FIG. That is, the cylinder (53) is attached to the support stand (54
) is tiltably supported by a horizontal shaft (55), and its piston rod (55a) is supported by a horizontal shaft (55) on both sides of the rotating shaft (41) (4
1), and is connected to each rotating shaft (41) to a fixed 7t lever (5B) via a pin (57).

The mechanical sensor (35) protrudes onto the roller conveyor (25) as shown in FIGS. 3 and 4, and when the transfer frame (48) is lowered, the steel piece (2C) is sent in, and this hits the stopper (58) (shown in Figure 2) and is stopped.
As the front-stage transfer device part (IIA) -1- is conveyed (and a sensor (not shown) detects this, the cylinder (53) shown in FIG. 3 works to rotate the rotating shaft (41).
) counterclockwise in the figure, and then rotate the mechanical sensor (
35) is lowered once as shown in FIGS. 5 and 6. At the same time, the transfer frame (48) is i-'y'/. By doing so, the shuttle car (50) moves to the position (a) shown by the broken line in Fig. 3.
From the dotted line position (b), hold the piece of steel (2C) placed on the front transfer/equipment part (IIA) and roll it. Next, the shuttle car (50) is moved to the left by the cylinder (52), and the steel piece (2C) is transferred to the roller conveyor (
25) and the mechanical sensor (35), move to the two-dot chain line position (C) and the solid line position in FIG. 5, and transfer the steel piece (2C) to the rear transfer device section (IIB) I-. As the steel piece (2C) is transported away from the shuttle car (50), the shuttle car (50), transfer frame (48), and mechanical sensor (35) move back.

In addition, if the steel billet (2C) is too warm in the front transfer device part (IIA) L, or if it has not reached the prescribed position even if it is present, the steel billet (2C) is placed in the second carry-in path (24). 2C) is carried in, the roller conveyor (25Ll
The sliding piece of steel (2C) is a mechanical sensor (35)
The proximity switch (40) is turned on by contacting the shuttle car (50), and the shuttle car (50) is first moved to the target position of the roller conveyor (25). In the meantime, the steel piece (2C) runs to the fixed position where it hits the stopper (58)? Then, the cylinder (53) operates, the mechanical sensor (35) lowers, and the transfer frame (48) moves to 1, the shuttle car (50) moves to the roller conveyor (25). ) l
Hold a steel piece (2C) of 1.

and then transferred to the subsequent transfer/equipment section (IIB). Therefore, the roller conveyor (
25) It is assumed that a similar transfer mechanism is provided to transfer the 11 steel pieces (2C) to the former transfer device section (lIA).

Furthermore, the front stage transfer device part (IIA) -1-
When the steel slab (2C) has reached the predetermined position and therefore is to be transferred, the new steel slab must be carried into the second loading path (24) until the transfer described in - is completed. shall be suspended.

It is also possible to replace the mechanical sensor (35) with a non-contact sensor such as an optical sensor, but in the case of an optical sensor, care must be taken to ensure that the sensor does not push the steel pieces to be transferred in the transport direction. This is not desirable because of the difficulties of the overall configuration I-.

In addition, a striker with a roller (37) is used for the mechanical sensor (35), but this is a steel plate (2C).
This is to absorb the impact caused by the roller rotation.

Furthermore, it goes without saying that the present invention can be applied not only to transfer devices for steel billet eaves removal equipment, but also to other uses.

(Effects of the Invention) As described in detail below, according to the present invention, when steel billets are carried into a funeral billet transfer device at multiple locations, each billet in the device 1- is transported during the conveyance process. Since the steel pieces are conveyed over the roller conveyor for carrying in the steel pieces, the steel pieces can be conveyed in an orderly manner, and the steel piece conveyance process described in step 11 can be carried out smoothly.
