[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the accompanying drawings.
1 and 2 show an installation example of a long material supply device according to the present invention, FIG. 1 is a plan view, and FIG. 2 is a side view. FIG. 3 is a side view of the sending means, and FIG. 4 is a front view of the aligning means.
As shown in FIG. 1 to FIG. 4, the main part of this long material supply device is constituted by a conveying means 1, a sending means 2, and an aligning means 3.
Hereinafter, each of the above components will be sequentially described in detail.
[0007]
The conveying means 1 conveys the long material A on the conveyor C in a direction (arrow L direction) orthogonal to the longitudinal direction.
As shown in FIGS. 1 and 2, the transport unit 1 includes a frame 11 forming a transport path X, and seven series of conveyors C1 to C7 arranged on the frame 11 in the width direction of the transport path X. A hook-like shape that moves up and down between the first and second conveyors C1 and C2 and the conveyors C6 and C7 from both ends of the transport path X at a predetermined distance downstream from the start end of the conveyor C and moves up and down on the conveyor C surface. A stopper S1 and a hook-like member that moves up and down between the first and second conveyors C1 and C2 and the conveyors C6 and C7 from both ends of the transport path further downstream from the stopper S1 to move up and down on the conveyor C surface. A stopper S2 is provided as a main component.
The transport path X formed on the frame 11 has a width that allows the long material A to be transported by being laid sideways in a direction orthogonal to the longitudinal direction.
The conveyors C are arranged side by side at an interval in parallel with each other, and the upper surface of the conveyor C is installed horizontally while maintaining the same height.
When the end of the long material has a different diameter portion, the conveyors C1 and C7 on both outer sides can be moved up and down by the lifting cylinder 14 so that the conveyor C does not descend and contact the different diameter portion. . .
The conveyor C is not particularly limited, such as a belt conveyor, a chain conveyor, and a roller conveyor, but a belt conveyor is preferable.
Reference numeral 12 in the figure denotes a detector formed of a photoelectric tube, which detects the presence or absence of the long material A on the conveyor C. Upon receiving the signal, the stopper S1 moves up and down on the surface of the conveyor C, and conveys or blocks the long material A on the conveyor C. Reference numeral 13 in the figure denotes a detector comprising a photoelectric tube, which detects the presence or absence of the long material A on the conveyor C. Upon receiving the signal, the stopper S2 moves up and down on the surface of the conveyor C to convey or block the long material A on the conveyor C.
[0008]
The conveying means 1 is configured such that the conveyors C rotate in synchronization with each other in the same direction. Can be transported.
When the presence of the long material A on the conveyor C is not confirmed from the detection result of the photoelectric tube 12, the stopper S1 stands up in response to the signal and stops the long material A conveyed on the conveyor C. . In addition, receiving the signal from the sending means 4, the conveyance of the long material A that has fallen down and is blocked is started.
When it is confirmed from the detection result of the photoelectric tube 13 that the long material A exists on the conveyor C for a predetermined time or more, the stopper S2 receives the signal and falls down to block the long material. The transfer of the material A is started.
[0009]
The sending means 2 sends the long material A, which is placed on the sending table 21 and temporarily stored, to the conveyer at appropriate times by a pushing rod 22 which advances and retreats.
As shown in FIG. 3, the delivery means 2 includes a delivery table 21, a pushing rod 22 moving forward and backward on the delivery table 21, a driving motor (not shown) for moving the pushing rod 22 forward and backward, and a standing end at the start end of the conveyor C. A wedge W is provided as a main component, and can be moved up and down on the conveyor C by an elevating cylinder 31 and can be advanced and retracted below the delivery table 21 by an advance / retreat driving cylinder 32.
The surface of the delivery table 21 has a predetermined inclined state, and the upper end is connected to the start end of the conveyor C. The inclination angle is preferably selected from the range of 5 to 30 °, more preferably 10 to 20 °. The long material A is placed on the delivery table 21 with its longitudinal direction orthogonal to the transport direction, and is temporarily stored. The stored long material A is pushed out by the pushing rod 22 in a direction orthogonal to the longitudinal direction, and is sent out onto the conveyor C.
The push rod 22 is an upright plate slidably mounted on the delivery table, and is advanced and retracted on the delivery table 21 by a drive motor (not shown) in parallel with the transport direction. Since the pushing rod 22 needs to uniformly push the longitudinal direction of the long material A, a plurality of pushing rods 22 are preferably arranged in parallel.
Reference numeral 23 in the figure denotes a detector comprising an ultrasonic sensor, which detects the loading level of the long material A on the conveyor C, and receives the signal to move the pushing rod 22 forward and backward. Reference numeral 24 in the drawing denotes a push-rod advance / retreat encoder. The push-rod moves forward and backward within a set value range, and performs only a forward movement when the set value is exceeded.
[0010]
The sending means 2 thus arranged is provided at the start end of the conveyor C provided on the transport path X.
The long material A is stacked on the mounting table 25 provided at the start end of the conveyor with its longitudinal direction aligned with the traveling direction. An elevating device 4 is provided at a position opposite to the transport path X via the mounting table 25.
The elevating device 4 includes the arm-shaped delivery table 21 for transferring the long material A, a frame 27 for moving the delivery table 21 up and down, and a guide 28 to which the frame 27 is attached. The unit is disposed with the unit facing the transport path X direction.
The delivery table 21 arranged below the mounting table 25 has a length capable of transferring the entire length of the long material A in the frame 29 provided on the mounting table 25 at one time. The length member A can be raised and raised to a predetermined height by the operation of the frame 27 without interfering with the mounting table 25 and the frame 29 provided on the mounting table 25 and the start end of the conveyor C.
After the long material A transferred on the delivery table 21 is lifted to a predetermined height and lifted to a predetermined height, the cylinder rod 30 of the tilting drive cylinder associated with the guide 28 retreats, so that the guide 28 is set at the standing point. , The delivery table 21 is formed, which is inclined to the rear side of the delivery table 21 and has an inclined surface whose upper end is in the transport path X direction. The upper end of the delivery table 21 is positioned so as to be connected to the start end of the conveyor C.
[0011]
The push rod 22 moves on the delivery table 21 in parallel with the transport direction. Above the start end of the conveyor C, the ultrasonic sensor 23 detects the loading level of the extruded long material A, and when the detection result is equal to or less than the set value, the push rod 22 receives the signal and the pushing rod 22 To push out the long material A on the delivery table 21 to the upper end of the delivery table 21.
When the push rod 22 advances and pushes the long material A to the start end of the conveyor C, the loading level of the long material A at the start end of the conveyor C increases. The ultrasonic sensor 23 detects the loading level of the long material A, and when the detection result is equal to or greater than a set value, the push rod 22 receives the signal and the push rod 22 retreats to the lower end of the delivery table 21. At this time, a part of the long material A extruded to the upper end of the delivery table 21 collapses on the inclined surface, and retreats together with the pushing rod 22 to the lower end of the delivery table 21 where the pushing rod 22 retreats.
When the long material A is loaded on the start end of the conveyor C, the wedge W is lifted by the elevating cylinder 31 and penetrates between the long materials A to send the long material A on the delivery table 21. And the long material A on the conveyor C.
When the wedge W rises and is divided into the long material A on the delivery table 21 and the long material A on the conveyor C, the stopper S1 of the transport means 1 falls down and is blocked by the stopper S1. The long material A is transported on the transport path X by the conveyor C, but since the long material A on the delivery table 21 is blocked by the wedge W, the appropriate number of long materials divided on the conveyor C Only A is transported at a time.
After the conveyance starts, when the photoelectric tube 12 no longer detects the long material A on the conveyor C, the stopper S1 stands up, then the wedge W descends, and the pushing rod 22 advances and retreats to repeat sending.
By repeating the sending in this manner, the amount of the long material A on the sending table 21 decreases. When the amount of the long material A decreases, the position at which the push rod 22 advances in one push is gradually approaching the upper end. If the position where the push rod advances at one time exceeds the set position of the push rod forward / backward encoder 24 on the delivery table 21, thereafter, the push rod 22 performs only the forward operation or the stop operation without performing the backward movement, and the forward travel limit is reached. It advances to the point and sends out the long material A onto the conveyor C.
When the pushing rod 22 has advanced to the limit point, a part of the long material A remains between the pushing rod 22 and the conveyor C.
Therefore, four of the wedges W at the starting end of the conveyor C, except for both ends, advance below the delivery table 21 and rise to the surface of the delivery table 21 without interfering with the delivery table 21. By retreating to the start end side of the conveyor C, all the long materials A on the delivery table 21 can be sent out onto the conveyor C.
[0012]
The aligning means 3 aligns the intersecting state of the long materials A stacked at the start end of the conveyor C.
As shown in FIGS. 3 and 4, the alignment means 3 mainly includes a wedge W which can be moved up and down in a gap between the conveyors C without interfering with the conveyors C at a predetermined distance downstream from the start end of the conveyors. Provided as an element.
The wedge W is disposed between the conveyors C1 to C7 with six wedges W1 to W6 at appropriate intervals in the width direction of the transport path X, and is erected on a straight line orthogonal to the transport path X. . The wedges W1, W6 located at both ends are disposed between the first and second conveyors C1, C2 and the conveyors C6, C7 from both ends of the transport path X.
It is preferable that the width and the thickness of the wedge W are set to be the largest in a range that does not make contact with the adjacent conveyor C in order to increase the alignment effect.
The shape of the wedge may be square or circular, but it is preferable that the tip is a pointed angle so that it can easily penetrate between the long members A.
[0013]
The arranging means 3 is configured such that the center wedge W3 is first raised by the drive cylinder 31 with respect to the long material A stacked in the crossing state at the start end of the conveyor C, and is positioned above the long material A. The wedge W3 is operated so as to penetrate and to form a gap on both sides in the longitudinal direction of the long material A of the wedge W3.
Next, the central wedge W4 rises and intervenes in the gap that has occurred earlier and penetrates upward to enlarge the gap.
Next, the wedges W2 and W5 on both outer sides of W3 and W4 are raised, and penetrate the gap previously generated upward to further expand the gap.
Finally, the wedges W1 and W6 at both ends rise and penetrate upward to further enlarge the gap, thereby making the axes of the long material A parallel and aligning the crossing state.
[0014]
Next, the operation of the long material supply device described above is shown in FIGS. 5 to 15 and will be described based on this.
First, a number of long materials A are placed on the mounting table 25 in the longitudinal direction orthogonal to the transport direction.
On the side opposite to the conveyor C with the mounting table 25 interposed therebetween, it is disposed at a position where the lifting / lowering means 4 can operate. The delivery table 21 provided in the lifting / lowering means 4 is arranged below the long material A without interfering with the mounting table 25 and the frame 29 loaded on the mounting table 25.
At this time, the wedges W (the six wedges W1 to W6) are at the raised position at the start end of the conveyor C, and immediately when the long material A is raised to the start end of the conveyor C by the elevating means 4, The transport is prevented from starting due to collapse (see FIG. 5).
[0015]
Next, the delivery table 21 rises together with the frame 27, transfers the long material A from the placement table 25 to the delivery table 21, and further places the placement table 25, the frame 29 installed on the placement table 25, and the start end of the conveyor C. And raises the long material A without interfering with it, and then rises to a predetermined height and stops (see FIG. 6).
[0016]
When the delivery table 21 rises to a predetermined height, the rod 30 associated with the guide 28 retreats, and as a result, the guide 28 inclines to the back side of the delivery table 21 about the upright point, and the long material A Is formed as a delivery table 21 having an inclined surface whose upper end is in the direction of the conveyor C. At this time, the upper end of the delivery table 21 is connected to the conveyor (see FIG. 7).
[0017]
When the delivery table 21 on which the long material A is transferred is inclined and the delivery table 21 having the inclined surface is formed, the wedge W is lowered by the operation of the lifting cylinder 31 at the start end of the conveyor C, and a part of the long material A is formed. Falls on conveyor C.
At this time, since both the stopper S1 and the stopper S2 are upright, the long material A that has collapsed is blocked by the stopper S1 (see FIG. 8).
[0018]
In the state where a part of the long material A has collapsed on the conveyor C, the loading level of the long material A at the start end of the conveyor C has not reached the set value of the start of conveyance, so the ultrasonic sensor which has detected the level has been used. Receiving the signal of 23, the pushing rod 22 advances, and pushes out the long material A from the delivery table 21 to the start end of the conveyor C.
When the pushing rod 22 advances on the delivery table 21 and pushes out the long material A, the long material A on the delivery table 21 is rocked by the force pushed by the pushing rod 22 near both ends in the longitudinal direction. The intersections are partially aligned (see FIG. 9).
[0019]
When the loading level of the long material A at the start end of the conveyor C reaches the set value, the push rod 22 retreats to the lower end of the delivery table 21.
At this time, a part of the long material A at the start end of the conveyor C falls on the delivery table 21 toward the lower end. By collapse on the delivery table 21, the pressed long material A relaxes the pressing state and a gap is generated between the long materials A, and when the pressing force is applied next, the crossing state is aligned. This is a state that is easy to perform (see FIG. 10).
[0020]
When the long material A is loaded on the start end of the conveyor C, the wedge W is lifted by the elevating cylinder 31 and penetrates between the long materials A to send the long material A on the delivery table 21. And the long material A on the conveyor C. The operation of the wedge W here is shown in FIGS.
At this time, the center wedge W3 rises and penetrates above the long material A, and a gap is generated on both sides in the longitudinal direction of the long material A of the wedge W3. At this time, a part of the intersecting state is aligned by applying a slight impulse to the long material A in the intersecting state (see FIG. 16).
[0021]
Next, the wedge W4 rises to the gap on one side of the wedge W3 that has been raised earlier, enlarges the gap, and the axis of the long material A approaches parallel (see FIG. 17).
[0022]
Subsequently, the wedges W2 and W5 rise in the gaps at both ends of the two rising wedges W3 and W4, and the gaps are further enlarged, and the axis of the long material A becomes closer to parallel (see FIG. 18). ).
[0023]
Subsequently, the wedges W1 and W6 at both ends rise in the gaps at both ends of the four rising wedges W2, W3, W4, and W5, and the gap is further enlarged. They are almost parallel and the intersections are aligned (see FIG. 19).
[0024]
When all the wedges W are raised and the intersections are aligned, the four wedges W2, W3, W4, and W5 at the center descend from the surface of the conveyor C, and the two wedges W1 and W6 at both ends rise. S1 falls down, and the long material A starts to be conveyed downstream by the conveyor C (see FIG. 11).
[0025]
FIG. 20 and FIG. 21 show the steps of the transfer means.
When the stopper S1 falls down and the conveyance is started, the long material A may skew in the conveyance direction of the conveyor C and reach the stopper S2 in a skewed state (see FIG. 21).
[0026]
At this time, since the stopper S2 is upright, one end of the long material that has been skewed and conveyed is stopped by the stopper S2, and is held until the other end reaches the stopper S2 (see FIG. 22). .
Both ends of the long material A arrive at the stopper S2, and the photoelectric tube 13 detects that the long material A continues on the conveyor C for a predetermined time or more. When it is confirmed that they are aligned, the stopper S2 falls down and starts transporting further downstream.
In this manner, skew at the end of the conveyor is prevented.
[0027]
When the conveyance is started, the long material A on the delivery table 21 is blocked by the wedge W, so that the long material A divided on the conveyor C is conveyed at a time. When the transport of the long material A present at the start end of the conveyor C is completed, the photoelectric tube 12 detects that the long material A does not exist at the start end of the conveyor C, and the stopper S1 stands up and the length on the delivery table 21 is raised. The wedge W that has blocked the length member A descends, the next extrusion operation is started again, and the above operation is repeated (see FIG. 12).
[0028]
When the pushing operation is repeated and the number of long materials A present on the delivery table 21 decreases, the position where the pushing rod 22 advances by one pushing gradually approaches the upper end. If the position where the push rod advances at one time exceeds the set position of the push rod 22 advance / retreat encoder 24, thereafter, the push rod 22 does not perform the retreat operation, but advances to the advance limit point and moves the long material A on the conveyor C. (See FIG. 13).
[0029]
As the push rod 22 continues to advance, it reaches the upper end of the delivery table 21.
However, at this time, some long material A remains between the pushing rod 22 and the start end of the conveyor C.
Here, the four wedges W2, W3, W4 and W5 excluding the both ends advance below the delivery table 21 by the drive cylinder 32, and then rise by the lifting cylinder 31 without interfering with the delivery table 21 and the pushing rod 22. To press the remaining long material A (see FIG. 14).
[0030]
Subsequently, the wedges W2, W3, W4, and W5 that rise and press the long material A are retreated to the start end side of the conveyor C by the drive cylinder 32, and all the long material A remaining on the delivery table 21 is transferred onto the conveyor C. (See FIG. 15).
[0031]
FIG. 22 shows another embodiment in which the delivery table 21 'is formed at the start end of the conveyor C, and is formed by fixing the delivery table 21' at the start end of the conveyor C. In this case, as a method of placing the long material A on the delivery table 21 ', a method of supplying the long material A to the delivery table 21' by a crane K or the like may be used.
[0032]
Examples of long materials that can be processed by the long material sizing device according to the present invention include round steel bars, rolled steel bars, synthetic resin bars, synthetic resin pipes, metal tubes, and wood.
As the caliber, a long material having a diameter of about 10 to 400 mm and a length of about 4 to 5 m can be processed, and is particularly suitable for a flexible material having a small caliber of about 10 to 40 mm in diameter. is there.
[0033]
