[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for laterally transporting a transport material. Specifically, a transport material such as a tube continuously fed on a transport line is sequentially paid out to the side of the transport line to perform the next process. The present invention relates to a method and an apparatus for laterally transporting a carrier to be sent out.
[0002]
[Prior art]
In a continuous small-diameter pipe production process, a continuously produced pipe is cut to a fixed length online, and then is discharged from a predetermined discharge position of a screw-type cooling bed. However, when the tip of the tube is slightly bent and deformed, that is, when the so-called nose bend occurs, the tube collides with the spiral portion of the screw of the screw-type cooling bed, and the tube cannot be transported to the predetermined dispensing position, and the side of the tube to the cooling bet. Problems such as interfering with feeding occurred.
[0003]
In order to improve this problem, the applicant has previously disclosed in Japanese Patent No. 2501641 that a pipe sent from a transfer line is paid out and sent out by a kick plate, and a nose bend occurs when the pipe is transferred to a cooling bed. We proposed a device that can stably transport tubes.
[0004]
FIG. 1 is a cross-sectional view showing an apparatus according to this proposal. As shown in the figure, the apparatus is a device that sequentially pays out the transport material P continuously sent on the transport line L, and then sends out the material to the next process. A payout device extending continuously to the transport line is provided at the end of the transport roller row of the transport line L, and a guide trough 1A that draws a concave arc in the payout direction is provided so as to guide the transport material. On the payout side of the guide trough 1A, a stop trough 1B that draws a concave arc in the payout direction is provided adjacent to and parallel to the guide trough 1A. On the guide trough 1A and the stopping trough 1B, the lower end advances from the standby position on the non-payout side of the trough to the payout side along the concave arc of the trough, and retreats above the trough toward the non-payout side. A kick plate 2 for payout and a kick plate 3 for delivery are provided respectively in conjunction with a series of one-way turning motions. The one pivoting movement of the kick plates 2 and 3 in the payout direction is performed by using a cam mechanism or the like as appropriate to move forward, backward, and circularly (e.g., circular or elliptical).

2 and 3 are explanatory diagrams each showing an example of an operation pattern of this device. . As shown in FIGS. 2 and 3, the kick plates 2 and 3 stand by at a point A with respect to the preceding transport material, the brakes are opened at the same time as the pipe kicking-out command, and the kick plates 2 and 3 collide with the pipes and engage the clutch. , The clutch is disengaged at the point C, then the operation is performed by inertia, the brake is closed at the point D, the operation is stopped at the point A, and the operation of waiting for the succeeding transport material is repeated. .
[0007]
[Problems to be solved by the invention]
This device surely pays out and sends out the pipes sent from the transfer line by the kick plate, and can also stably transfer the pipe with the bent nose when transferring to the cooling bed. Yes, with sufficient utility.
[0008]
However, the present inventors have conducted further studies in order to further improve the performance of this apparatus, and as a result, this apparatus temporarily stops the kick plates 2 and 3 at the point A every time one transport material is sent out. Since it is necessary to use clutches and brakes inevitably, if it is arranged in the mass production process of pipes, time loss due to temporarily stopping the kick plates 2 and 3 and clutch and brake due to frequent on / off Increasing the repair cost due to a brake failure and further increasing the turning speed of the kick plates 2 and 3 are difficult to prevent the hitting of the pipe due to a collision because the kick plates 2 and 3 are rotated at a constant speed. It was found that there were issues such as.
[0009]
The present invention has been made in view of the above-mentioned problems of the conventional technology, and it is possible to sequentially and efficiently discharge a transfer material such as a pipe that is continuously sent on a transfer line to a side of the transfer line. It is an object of the present invention to provide a method and apparatus for traversing a transport material that can be used.
[0010]
[Means for Solving the Problems]
FIG. 4 is a graph showing a change in angular velocity (kicker angular velocity) of one cycle of the kick plates 2 and 3 of the above-described apparatus shown in FIGS. As shown in the drawing, it is necessary to stop the kick plates 2 and 3 once at the point A every time one transport material is fed in order to pay out both the preceding transport material and the following transport material. For this reason, it is necessary to rapidly accelerate and decelerate the kick plates 2 and 3, and it is necessary to increase the motor drive capacity. For this reason, the clutch and the brake become indispensable.
[0011]
Therefore, the payout of the transfer material is continuously performed by using a method in which the kick plates 2 and 3 are continuously rotated so as to be in time for the discharge of the transfer material after the completion of the discharge of the preceding transfer material, that is, a continuous operation method. I thought. FIG. 5 is a graph showing the change over time of the angular velocity (kicker angular velocity) of the kick plates 2 and 3 in one cycle by the continuous operation method with time.
[0012]
By operating the kick plates 2 and 3 continuously as shown in FIG. 5, the acceleration of the kick plates 2 and 3 can be kept relatively low.
Further, by using a low-capacity inverter motor as a drive source for turning the kick plates 2 and 3, when the transport material is kicked, the kick can be performed at a constant speed that does not cause a scratch on the transport material. At the same time, the inventors have found that it is possible to reduce failures and repair losses due to repeated on / off operations of the clutch and the brake, and to shorten the kick cycle time.
[0013]
The present invention has been made based on these findings.
The present invention is a lateral feeding method for sequentially paying out at least a preceding transporting material and a following transporting material, which are continuously transported on a transport line, to a side of the transport line by a revolving kick plate. The kick plate is kept rotating at least from the time when the preceding transport material reaches a position upstream of a predetermined distance from the kick plate payout position until the time when the following transport material reaches this position. This is a method for laterally transporting a transport material.
[0014]
Further, the present invention is a lateral feeding method for sequentially paying out at least a preceding transport material and a succeeding transport material to a side of the transport line, wherein the transport material is continuously transported on a transport line, When the material reaches a position upstream by a predetermined distance from the payout position by the kick plate that is turned for payout, the kick plate is set in the vicinity of the transfer material immediately before the transport material reaches the payout position. So that the kick plate is accelerated or decelerated without stopping without turning, and is arbitrarily set at a constant speed until the kick plate collides with the preceding conveying material and reaches a preset turning angle. Conveying material is paid out by continuing to rotate the kick plate, and the succeeding conveying material is positioned a predetermined distance upstream from the payout position by the kick plate. Until it reaches the a lateral feeding method of the transfer material, characterized in that to wait without stopping the kick plate.
[0015]
In the method for laterally feeding a transport material according to the present invention, it is desirable that the kick plate be turned using an inverter motor or another variable speed motor as a drive source.
[0016]
In the method for laterally feeding a transport material according to the present invention, it is exemplified that the transport material is a tube.
In another aspect, the present invention provides a kick plate that is continuously conveyed along a conveying line, and that pivots to sequentially discharge at least a preceding conveying material and a following conveying material to a side of the conveying line. A control device that detects that the transport material has reached a position upstream by a predetermined distance from the payout position by the kick plate and controls the turning speed of the kick plate, and the control device includes at least a preceding transport material. Is a lateral feeding device for a transport material, wherein the kick plate is continuously rotated from when it reaches a position upstream by a predetermined distance to when the subsequent transport material reaches this position.
[0017]
The present invention also provides a kick plate which is continuously conveyed on a conveying line, and which pivots to sequentially pay out at least a preceding conveying material and a succeeding conveying material to the side of the conveying line, and the conveying material includes a kick plate. A controller that detects that the plate has reached a position upstream by a predetermined distance from the payout position and controls the swing speed of the kick plate. When the transport material reaches the position upstream by the distance, the kick plate accelerates or decelerates without stopping so that the kick plate reaches a preset position near the transport material just before the transport material reaches the payout position. Turn the kick plate at an arbitrarily set constant speed until the kick plate collides with the preceding transport material and reaches the preset turning angle. By continuously rotating the kick plate, the transfer plate is paid out, and the kick plate is made to stand by without stopping until the following transfer plate reaches a position upstream by a predetermined distance from the kick plate discharge position. This is a horizontal feeder for conveying materials.
[0018]
In the transporting apparatus according to the present invention, it is preferable that the kick plate be turned by an inverter motor or another variable speed motor as a drive source.
[0019]
In the transporting apparatus for transporting materials according to the present invention, it is exemplified that the material to be transported is a pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a method and an apparatus for laterally feeding a transport material according to the present invention will be described in detail with reference to the accompanying drawings. In the following description, the above-described FIGS. 1 to 4 will be referred to as appropriate, and in that case, the overlapping description of FIGS. 1 to 4 will be omitted as appropriate. In the following description, a case where the transport material is a tube will be described as an example.
[0025]
In the present embodiment, the present invention is applied to the apparatus 4 shown in FIG. 1 described above, which sequentially pays out the pipes P continuously sent on the transport line L and sends out the pipes P to the next process.
[0026]
As shown in FIG. 1, at the end of the row of transport rollers on the transport line L, a payout device extending continuously to the transport line is provided, and the guide trough 1A that draws a concave arc in the payout direction can guide the tube. In addition, a stop trough 1B that draws a concave arc in the payout direction is provided in parallel with the guide trough 1A on the payout side of the guide trough 1A. On the guide trough 1A and the stopping trough 1B, the lower end advances from the standby position on the non-payout side of the trough to the payout side along the concave arc of the trough, and retreats above the trough toward the non-payout side. A kick plate 2 for payout and a kick plate 3 for delivery are provided respectively in conjunction with a series of one-way turning motions. The one pivoting movement of the kick plates 2 and 3 in the payout direction is performed by using a cam mechanism or the like as appropriate to move forward, backward, and circularly (e.g., circular or elliptical).
[0027]
In the present embodiment, an inverter motor 6 is used as a drive source for the kick plates 2 and 3. The “inverter motor” is an AC interlocking machine for variable speed control, and is a motor whose speed can be arbitrarily changed by a frequency.
[0028]
In the present embodiment, the operation of the kick plates 2 and 3 is controlled by a control device (not shown) as described below.
It is detected by a known suitable means that the preceding pipe has reached a position upstream of the payout position by a predetermined distance before reaching the payout position by the kick plates 2 and 3. After the detection, the timer is operated, and the kick motors 2 and 3 are kicked by the inverter motor 6 so that the kick plates 2 and 3 slightly moving near the point E in FIG. By accelerating and / or decelerating the plates 2, 3, they reach a preset angle near the tube. Further, the turning operation of the kick plates 2 and 3 is continued at a fixed speed arbitrarily set up to a preset angle. Note that the constant speed is a speed at which a flaw does not hit the pipe during conveyance. Then, after the dispensing is completed, the subsequent pipes reach the dispensing position by the kick plates 2 and 3 while the kick plates 2 and 3 are continuously operated without stopping to prevent rapid acceleration and / or sudden deceleration. Then, it waits to reach a position upstream of the payout position by a predetermined distance.
[0029]
FIG. 6 is a vertical cross-sectional view of the transport step in the present embodiment. As shown in the figure, the transport process L in the present embodiment is arranged on the entrance side of the cooling bed B from the previous process, and the present invention is provided on the side of the transport line L on the opposite side of the cooling bed B. A large number of the applied devices 4 are arranged at intervals in the line direction. Each device 4 is linked by a drive shaft 5.
[0030]
As described above, the drive shaft 5 is accelerated and / or decelerated by the inverter motor 6 provided at the end of the line.
The transport step in the present embodiment is configured as described above. Next, the situation in which the pipe is discharged in this transport step will be described with time.
[0031]
(1) When the pipe is cut to a fixed length, the pipe is accelerated and transported. The above-described control device (not shown) detects that the rear end of the pipe has passed the kick-out kick plate end Y from the most entry side in FIG. 6 and simultaneously activates the timer. Then, after the timer is up, the kick plates 2 and 3 that slightly move near the uppermost position E in FIG. 3 are moved immediately before contact with the pipe (when the lowermost position of the circular motion is 0 °, for example, (340 °) is controlled by accelerating and / or decelerating the angular velocity of the kick plates 2 and 3 by the inverter motor 6 so as to come to the position.
[0032]
(2) After the kick plates 2 and 3 reach the position immediately before contact with the pipe (when the lowermost position of the circular motion is 0 °, for example, 340 °), the pipe does not have flaws. In order to do so, the preceding pipe is dispensed by causing the inverter motor 6 to perform a circular motion at a constant speed up to a preset angle (for example, 40 °).
[0033]
(3) After the leading pipe is paid out, the kicking plates 2 and 3 are continuously operated without stopping by the inverter motor 6 to prevent sudden acceleration and / or sudden deceleration, and the trailing pipe is moved to the kick plate 2 Before reaching the payout position by (3), the robot stands by while slightly moving near the uppermost position E in FIG. 3 to reach a position upstream by a predetermined distance from the payout position.
[0034]
According to the present embodiment, the kick plates 2 and 3 are continuously turned without stopping by using the inverter motor 6 as a drive source, so that it is not necessary to use a clutch and a brake. Can be suppressed, and the transporting ability can be enhanced, and the transporting material can be transported without being damaged.
[0035]
That is, since the clutches and brakes are not used, time loss caused by temporarily stopping the kick plates 2 and 3 and an increase in repair costs due to clutch and brake failures due to frequent on / off can be eliminated. Conveying materials such as pipes that are continuously fed can be sequentially and efficiently discharged to the side of the conveying line.
[0036]
(Modified form)
In the above description, the positions where the kick plates 2 and 3 wait while moving slightly. Although point E (the position at 180 degrees), which is the uppermost portion in FIG. 3, is of course, it can be arbitrarily changed in consideration of the capacity and usability of the inverter motor.
[0037]
Further, in the above description, the case where the conveying material is a tube is taken as an example, but the present invention is not limited to the tube, and the conveying material other than the tube, such as another continuously conveyed rod material. It goes without saying that the same applies to.
[0038]
Further, in the above description, the case where an inverter motor is used as a drive source of the kick plate is taken as an example, but a variable speed motor other than the inverter motor may be used.
[0039]
