Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dispensing control device for conveyed material on the exit side of a cooling bed of a section rolling facility, for example.

Normally, a wide variety of products are rolled in a section steel rolling facility. The cooling bed is operated so that the material spacing or material pitch of the transported material is at least a certain size depending on the size, weight, shape, etc. of the rolled material, taking into account cooling efficiency and bending due to cooling. . However, on the outlet side of the cooling bed, bending occurs due to the cooling effect on the cooling bed, and the material pitch or spacing is irregular. For this reason, in conventional cooling bed outlet equipment, materials are transported using equipment configured as shown in FIG.

FIG. 1 shows the configuration of the outlet side of the cooling bed when viewed from a direction perpendicular to the direction in which the material travels. In the figure, the material 7 is sent to the end of the cooling bed 1 while being cooled by the cooling bed 1. In other words, this material 7 is
It is lifted up by the output side transfer 2 controlled by and conveyed to the output side table 3. In addition, at this time, not only one material but also two or three or more materials are transported. In this way, when the material 7 reaches the output table 3, the output transfer 2 is lowered and the material 7 is placed on the output table 3, and then the output transfer 2 remains in the lowered state and is placed on the output table 3. Material 7 cooling bed 1
Return to the end position of. In addition, the position where the material 7 transported in the above is placed on the exit table 3 is determined by the processing process of the finishing equipment after the exit table 3, but the position where the material 7 is placed on the exit table 3 is determined by the processing process of the finishing equipment after the exit table 3. It is necessary to place it in the center of the side table 3 or to place the end of the material 7 on the end of the output table 3.

FIG. 2 shows the operating range of the outlet transfer in such cooling bed outlet equipment and the general configuration of the operation during material discharging. In other words, the operating range of the outlet transfer 2 is such that its left end in the figure extends to point B, which is considerably upstream from point A, which is the maximum feed range position of the cooling bed 1, on the cooling bed 1 side, and its right end in the figure extends to the outlet side. On the table 3 side, the stroke is to near point C at the right end of the output table 3 in the figure.

When carrying out the material in such a configuration, the outlet transfer 2 is first lowered to a position where the most advanced material 7 that has been sent on the cooling bed 1 is placed, then moved back up, and the material 7 is transferred to the outlet transfer Place it on Ar2. Next, the output side transfer 2 is moved forward while being raised and conveyed onto the output side table 3. On the exit table 3, the forward movement of the exit transfer 2 is stopped at a predetermined position and then lowered. As a result, only the material 7 is placed on the outlet table 3, and the first dispensing is completed. Then, the output side transfer 2 is moved back to the work of discharging the next material while remaining in the lowered state. At the exit side of the cooling bed of the section steel rolling facility, the material 7 on the cooling bed 1 is discharged to the exit table 3 by repeating such operations.

By the way, in such a material dispensing device, first, on the cooling bed 1 side, the number of discharge side transfers 2 required to lift a predetermined number of materials, for example, one or two, from the most advanced material on the cooling bed 1 is determined. In determining the raising position, conventionally, a position indicator for the output transfer 2 is provided and the output transfer 2 is raised by looking at it or by manually adjusting the position indicator. Therefore, when the ejection side transfer 2 is raised in a wrong position, the material 7 to be delivered is often tipped over, or the next material is caught on top of the material 7, causing a problem in the operation pitch of material delivery. Further, there is a drawback that the material cannot be placed accurately at a predetermined position on the output table 3, which may interfere with the next process.

The present invention was made to eliminate the above-mentioned drawbacks, and its purpose is to reliably lift a predetermined number of materials on the cooling bed from the most advanced material at the exit transfer, and to It is an object of the present invention to provide an automatic dispensing control device for conveyed materials that can reliably dispense materials onto a table at a predetermined position.

In order to achieve the above-mentioned object, the present invention provides a control device for discharging the conveyed materials on the cooling bed, which are sequentially transferred to the dispensing possible range, onto the dispensing table by driving the discharging transfer with an electric motor. , a cooling bed position detector that is attached to the cooling bed and detects the transfer position of the cooling bed, and a material that is installed a predetermined distance upstream from the reference point of the range that can be discharged on the cooling bed and outputs a signal of the presence or absence of the transported material.

First, the concept of the present invention will be described with reference to the drawings. FIG. 3 shows the positional relationship among the cooling bed 1, the exit transfer 2, the exit table 3, and the material 7 in the cooling bed exit equipment.
The same parts as in FIG. 2 are designated by the same reference numerals. In the figure, the width of the material 7 moving on the cooling bed 1 is T ₁ , T ₂ ,
... and the intervals P ₁ , P ₂ , ..., a material detector 9 is installed near the dischargeable range on the cooling bed 1. This material detector 9 may be a photoelectric detector, for example, and the photoelectric detector is in a light-shielded state.
It is possible to actually measure the widths of the materials T ₁ , T ₂ , . . . and also to measure the distances between the materials P ₁ , P ₂ , . Further, this material detector 9 is installed at a distance of L ₁ from the illustrated reference point D of the cooling bed 1. Here, the distance L ₁ is a fixed distance value determined by the cooling bed outlet equipment. On the other hand, l ₁ is from the reference point D of the cooling bed 1 in order to lift the cutting edge material 7 on the cooling bed 1 from the point E of the left end of the outlet transfer 2 shown in the figure with a dimensional margin of S. is the distance. Here, it is preferable and safe for the point E to be located at the center between the materials 7, so the margin S is set to P ₁ /2.

From this, the distance _l1 can be calculated based on _l1 =( _P1 /2+ _T2 + _T3 + _T4 + _P2 + _P3 + _P4 ) _-L1 .

On the other hand, _L2 is the distance from the reference point D of the cooling bed 1 to the center point F of the outlet table 3, and this distance _L2 is also a fixed distance determined by the cooling bed outlet equipment. Further, l ₂ is the distance from the reference point D to the left end point E' of the output transfer 2 when the center of the material 7 is placed at the center point F of the output table 3. This distance l ₂ can be calculated based on l ₂ =L ₂ -(T ₁ +P ₁ /2).

In addition, when carrying out two materials 7 in the above, as shown in FIG. 4, the center of the two materials 7 is
It is carried out so that it is at the center point F of the delivery table 3. In other words, the distance l ₁ when carrying out two bottles is l ₁ = (P ₂ /2 + T ₃ + T ₄ + P ₃ + P ₄ ) - L ₁ , and the distance l ₂ is l ₂ = L ₂ - (P ₁ + P ₂ /2+T ₂ ). Further, when three or more pieces are to be carried out, the calculation can be performed in a similar manner. Furthermore, when placing the material 7 on the output table 3, instead of aligning the center of the material with the center point F of the output table 3, if placing the material 7 at a position that deviates from this, the value of the fixed value _L2 should be changed. By varying it, it is possible to place it at a predetermined position that is shifted from the position. In other words, in both cases the width of the material on the cooling bed 1
By actually measuring T ₁ , T 2 , _. . . and the intervals P ₁ , P ₂ , . . . , the discharge position of the material 7 can be accurately calculated.

In order to detect the material width and material spacing of the conveyed materials on the cooling bed that sequentially enter the dispensing range, the present invention provides a material detector that outputs a material presence/absence signal on the upstream side of the dispensing range reference point on the cooling bed. Based on the output signal from this material detector, the output transfer is moved to the raised position on the cooling bed side and the lowered position on the output table side every time the scheduled number of conveyed materials is discharged. This is intended to control the positioning and discharge of the conveyed material.

An embodiment of the present invention based on the above concept will be described below. FIG. 5 is a block diagram showing an example of the configuration of an automatic conveyance material dispensing control device according to the present invention, and the same parts as in FIGS. , only the different parts will be described here. In the figure, reference numeral 10 indicates a cooling bed position detector (hereinafter simply referred to as a position detector) 11 attached to the drive shaft of the cooling bed 1, and a material detector 9 with or without material (for example, a photoelectric converter). If available, light blocking/lighting signal)
In the position detection unit, each detection output signal is input, and the material widths T ₁ , T ₂ , ... and the material intervals P ₁ ,
It detects P ₂ ,... Here, the position detector 11 detects the moving position of the cooling bed 1 using, for example, a rotation angle detector (R/D converter). 12 is the output signal of the position detection section 10
A storage unit that stores T ₁ , T ₂ , ..., P ₁ , P ₂ , ...,
By dispensing material 7, the corresponding dimensions of the dispensing material,
For example, it is configured to sequentially erase T ₁ and P ₁ from its memory. Further, 18 is a setting device for setting the number of dispensed materials 7, and 13 and 14 are the setting output signal value of this setting device 18 and the storage section 12.
In the first and second distance calculation sections, the stored output signal values of Distance to transfer 2 end l ₁
and _l2 , respectively, and output the output as a distance setting signal. On the other hand, 19 is an output side transfer position detector (hereinafter simply referred to as a position detector) attached to the drive shaft of the output side transfer 2, such as a rotation angle detector (R/D converter), etc. This is used to detect the transfer position of the output transfer 2. A1 and A2 are the output signal of this position detector 19 and the control switch 15.
and 16, respectively, to obtain a deviation signal from the distance setting signals of the distance calculating sections 13 and 14, respectively. Further, reference numeral 17 denotes a positioning device which inputs each deviation output signal of the adders A1 and A2, and outputs a speed signal according to each deviation signal, and outputs a speed signal corresponding to each deviation signal.
By driving the drive motor 21 through the cooling bed 1 side, the output side transfer 2 is positioned and controlled to the raised position on the side of the cooling bed 1 and the lowered position on the side of the output table 3, respectively. In the above description, the control switches 15 and 16 set distance setting signals l ₁ and l ₂ respectively to the output transfer 2 in accordance with the discharging of the material 7, and to the positioning device 17 by their operation. In other words, when the material on the cooling bed 1 is lifted up and moved to the cooling bed 1 side during material discharging according to the material dispensing command, the switch 15 is set to l ₁ , and when the material is moved to the delivery table 3 side, the switch 16 is set. l ₂ is configured to control the settings respectively.

Next, the operation of such a configuration will be described by taking as an example the setting of the setting device 18, that is, the case where the number of pieces of material 7 to be dispensed is set to one. Material 7 on cooling bed 1
When the material 7 sequentially enters the dispensing range, the presence or absence of the material 7 on the cooling bed 1 is detected by the material detector 9 consisting of a photoelectric detector. As a result, a light shielding signal is applied when the material 7 is present, and a light projection signal is applied when the material 7 is absent, to the position detecting section 10 as an output signal. The position detection unit 10 uses these detection signals to determine the material widths T ₁ , T ₂ , ... and material spacing of the material 7.
P ₁ , P ₂ , . . . are actually measured, and each actual measurement value is stored in the storage section 12 at the next stage. In addition, each distance calculation unit 1
3 and 14, the elevated position of the outlet transfer 2 on the cooling bed side for discharging the material 7 and the outlet table are determined based on the stored value of the storage unit 12 and the setting value of the setting device 18. The descending positions on the third side, that is, the distances l ₁ and l ₂ from the reference point D of the cooling bed 1 described above are calculated, respectively. That is,
In the case of this illustrated example, the number of dispensed pieces of material 7 is 1.
Since it is a book, the first distance calculation unit 13 calculates the distance l ₁
As l ₁ = (P ₁ /2 + T ₂ + T ₃ + T ₄ + P ₂ + P ₃ + P ₄ ) - L ₁ , the second distance calculation unit 14 sets the distance l ₂ as l ₂ = L ₂ - (P ₁ + T ₁ /2) are respectively calculated and output. Now, in this situation, if a command to dispense materials is given,
The operation of the switch 15 causes the first distance calculation unit 1 to
A distance setting signal _l1 of 3 is set and added to the adder A1. On the other hand, the position of the output transfer 2 is detected by a position detector 19 attached to the drive shaft of the output transfer 2, and its output position signal is added to the adder A1. As a result, in the adder A1, the distance setting signal l ₁
The deviation (position) between the output position signal and the output position signal is detected, and the output signal is applied to the positioning device 17. Then, the positioning device 17 gives a speed signal corresponding to the deviation signal to the output transfer drive control device 20, and the output transfer drives the drive motor 21, so that the output transfer 2 moves to the cooling bed 1.
It is positioned at the raised position (loading position) on the side, that is, at a distance l ₁ from the reference point D of the cooling bed 1. When this positioning is completed, the ejection side transfer 2 is raised by the elevating device 4, and the leading edge material 7 is placed thereon and lifted. Next, in this state, switch 15 is deactivated and switch 1 is turned on.
6, the second distance calculation unit 1
A distance setting signal _l2 of 4 is set and added to the adder A2. As a result, in the adder A2, the output position signal of the position detector 19 and the distance setting signal l ₂
The deviation (position) from the position is detected and its output signal is applied to the positioning device 17. Then, the positioning device 17 gives a speed signal corresponding to this deviation signal to the output side transfer drive control device 20, and by using the output to move the drive motor 21 away, the output side transfer 2 is moved to the output side while being raised. table 3
l ₂ from the lowered position above, that is, the reference point D of cooling bed 1
The object is moved to a certain distance and positioned. When this positioning is completed, the ejection side transfer 2 is lowered by the elevating device 4 to place one material 7 at a predetermined position on the ejection table 3 and perform the first material discharging. finish. After that, when the material 7 is completely discharged, the discharge side transfer 2 remains lowered and retreats to the cooling bed 1 side for the next second material discharge. Applicable actual measurement value
Memories of T ₁ and P ₁ are released. Thereafter, the second and subsequent materials 7 are dispensed through the same process as described above.

In this way, in the device in which the conveyed material 7 on the cooling bed 1 that sequentially enters the dispensing possible range is delivered to the discharging table 3 by the discharging side transfer 2, the material 7 near the dispensing possible range on the cooling bed 1 A material detector 9 consisting of a photoelectric detector is installed at the location, and the position detection unit 10 detects the material width T and material interval P of the material 7, and each time the material 7 is dispensed, these detected amounts T and P are detected. , constants L ₁ , L ₂ and the number of dispensed pieces set in the setting device 18, the distance calculation units 13 and 14 calculate and set the control positions l ₁ and l ₂ of the outlet transfer 2, and the output transfer A2
The material 7 is dispensed by controlling the material 7 to be positioned at the set control positions l ₁ and l ₂ , that is, the raised position and the lowered position, respectively.

Therefore, the material 7 on the cooling bed 1 is transferred to the outlet table 3.
When discharging upward, the output transfer 2 can be precisely controlled to move to the raised position above the cooling bed 1 and the lowered position above the output table 3 as described above, so that the output is not carried out like in the past. side transfer 2
This eliminates the possibility of the conveyed material 7 being lifted up from the cooling bed 1 falling over due to a poor lifting position, or the next conveyed material 7 being caught and falling over. 7 can be placed accurately in a predetermined position. As a result, there is no possibility that the operation pitch during the transportation of the material 7 will be disturbed or that the next process will be hindered, and the material 7 can be delivered in an extremely stable and reliable manner. In addition, since the positioning of the output transfer 2 is performed based on the actual measurement of the material width and material spacing of the conveyed material 7, there is no need to manually set the positioning as in the past. Therefore, the positioning control can be performed extremely easily and automatically, and its reliability can be further improved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be similarly implemented in the following manner.

In the above embodiment, the case was described in which the conveyed materials were sequentially delivered one by one, but for example, two
Even in the case of dispensing more than one book at a time, it can be similarly implemented by setting the distance as described above. Furthermore, in the above embodiment, a photoelectric detector is used as the material detector, but it goes without saying that this is not the only option, and other detectors may be used as long as they have the same function. stomach.

In addition, the present invention can be modified and implemented in various ways without changing the gist thereof.

As explained above, according to the present invention, the positioning of the output side transfer is controlled, so that a predetermined number of conveyed materials are reliably lifted from the cooling bed and are also reliably placed at a predetermined position on the output table. Furthermore, it is possible to provide an extremely reliable automatic dispensing control device for conveyed materials that can be easily disbursed.
