Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a material separation device that can be easily changed according to the material shape.
[0002]
[Prior art]
In the case of supplying materials to a conventional forging press or the like, the materials falling continuously from the carry-in chute are separated one by one and carried into a forging press or the like. Those described in JP-A No. 101335, No. 6-34027, No. 7-39471, etc. are known.
[0003]
Of the above publications, the material separating apparatus described in Japanese Utility Model Publication No. Hei 3-101335 and Japanese Utility Model Publication No. 6-34027 separates the material that continuously falls from the carry-in chute one by one using the pusher means. The material is conveyed into the press body by a material conveying means such as a feeder.
[0004]
Moreover, the material separating apparatus described in Japanese Utility Model Publication No. 7-39471 separates one of the materials continuously dropped from the conveying chute by a material conveying apparatus such as a feeder and carries it into the press body. The attachment can be changed according to the size.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional material separating device, when the shape of the material processed by a forging press or the like is changed from, for example, a shaft to a flat plate, or conversely, from a plate to a shaft, the separating device is changed each time. It was necessary to replace the entire carrying chute together with the main body to match the shape of the material, and there was a problem that required a lot of time and labor for the replacement work.
[0006]
In addition, since many sensors for detecting the presence and position of materials are installed in the carry-in chute, when changing the carry-in chute, it is necessary to perform setup change work such as replacing the wiring of the sensors. There is a problem that a lot of man-hours are required for the setup change work.
[0007]
Furthermore, in the conventional material separating apparatus, since there is no bypass means for bypassing the material dropped from the carry-in chute, when separating the preheated material as in hot forging, the temperature is partially applied to the material. When there is a risk that a defective product may be generated when it is brought into the press body, or when a predetermined number of processing is completed and another material is processed next, It was necessary to manually remove the deteriorated material and the material remaining in the carry-in chute, resulting in problems such as poor workability.
[0008]
The present invention has been made to remedy such problems, and an object of the present invention is to provide a material separating device in which the carry-in chute can be easily replaced and the material can be bypassed.
[0009]
[Means for solving the problems and effects]
In order to achieve the above object, the invention according to claim 1 is a material separating apparatus,
A carry-in conveyor for conveying the material to be processed ;
A main body of the material separating apparatus for separating the materials one by one and feeding them to the press;
The carry-in conveyor side is high, the separator main body side is inclined so as to be low, and the material is dropped from the carry-in conveyor to the separator main body, and a carry-in chute is provided .
The separator main body, a pusher means for causing movement to the first material transfer position by separating the material to continuously drop the material falling position than the loading chute one by one,
A positioning means for stopping by positioning the material to continuously dropped from the loading chute to the second material transfer position,

When the material is a shaft material, the carry-in chute is a first carry-in chute that has a shape that guides the material to the material dropping position,
When the material is a plate material, the carry-in chute is a second carry-in chute having a shape that guides the material to the second material delivery position,
According to the shape of the material, the first carry-in chute and the second carry-in chute can be exchanged.
With the above configuration, even when the material to be processed is changed from a shaft material to a plate material, it is only necessary to replace the carry-in chute connecting the carry-in conveyor and the separation device main body. Compared with the case where the entire chute is replaced, the replacement work can be easily performed in a short time.
[0011]
In addition, since the conveyance of the material is performed by the carry-in conveyor, it can be shared by both the shaft material and the plate material, and it is not necessary to provide a conveying means for each material. By providing a carry-in conveyor, the length of the carry-in chute to be replaced can be shortened, and this allows the carry-in chute to be replaced manually, so that the setup change operation becomes extremely easy and the material supply position can be lowered. Therefore, it is possible to reduce the size of the carry-in conveyor and facilitate maintenance.
[0012]
In order to achieve the above object, the invention according to claim 2 is provided with a bypass chute for discharging the material being conveyed to the separator main body,
If the material of the shaft-like material, in the material the material drop position, provided the first bypass means for bypassing said material into the bypass chute,
If the material of the plate material material, the lower portion of the second loading chute, provided the second bypass means for bypassing said material into the bypass chute,
Depending on the material shape is obtained by so as to selectively operate the said first bypass means and said second bypass means.
[0013]
With the above configuration, when the temperature of the material drops below a predetermined temperature during material conveyance, the material can be bypassed from the line by the bypass means, and the work can be completed by completing a predetermined number of processes, When starting material processing, all of the material remaining on the carry-in chute can be discharged from the carry-in chute by the bypass means, so there is no need to remove the material manually.
[0014]
The invention of claim 3, wherein for achieving the above object, in the material the material falling position and the second plate material material transfer position, provided with a detecting means for detecting the quality of the material,
Based on a signal from the detecting means is obtained by the so controlled and the first bypass means and said second bypass means.
[0015]
With the above configuration, since the defective material can be automatically discharged, the apparatus can be automated and unmanned.
[0016]
In order to achieve the above object, the invention according to claim 4 is provided with detecting means for detecting the material 3 in the middle of the first carry-in chute and the second carry-in chute.
[0017]
With the above configuration, it is not necessary to change or adjust the detection means each time the carry-in chute is replaced, so that the setup change time can be greatly shortened.

The carrying chute 11 is different in shape in the case of the shaft material 3a and in the case of the plate material 3b, and can be exchanged according to the material shape.
The carry-in chute 11 is detachably attached to a support base 10a provided on the separating apparatus main body 10 side, and is inclined so that the carry-in conveyor 4 side is high and the separating apparatus main body 10 side is low. As shown in FIGS. 1 and 2, the carry-in chute 11 to be supplied to the separation apparatus main body 10 is configured to continuously drop while the upper and lower surfaces of the shaft material 3 a are in close contact with each other. The lower end portion of the chute 11 is a cylindrical lower chute 11a that is curved, and the lower chute 11a drops onto the table 10b of the separating apparatus main body 10 with the axis of the shaft material 3a being almost vertical. It is like that.

Further, on the upstream end side of the carry-in chute 11, a full work detection means 13 for detecting whether the shaft material 3a is in the full state in the cold-forge carry-in chute 11, and on the downstream side, the warm-forged shaft material 3a. The full work detection means 14 for detecting the temperature of the warm forging shaft material 3a and the presence or absence of the cold forging shaft material 3a are displayed on the table 10b at the material drop position. The material detection means 16 to detect is each installed.
[0024]
On the other hand, the separating apparatus main body 10 uses the pusher means 18 when separating the shaft material 3a and the lift means 20 described later when separating the plate material 3b.
As shown in FIGS. 7 and 8, the pusher means 18 is provided with a slider 18 a below a support base 10 a that supports the carry-in chute 11.

As shown in FIG. 7, the bypass plate 20a has an elongated rectangular shape in a direction orthogonal to the material conveyance direction A, and can be moved in a direction orthogonal to the material conveyance direction A by a bypass cylinder 21 connected to one end side. A bypass hole 20b having a diameter sufficiently larger than the outer diameter of the shaft article material 3a is opened on one end side of the bypass plate 20a, and the bypass plate is set so that the bypass hole 20b becomes the material dropping position B. By moving 20 a by the bypass cylinder 21, one of the shaft material 3 a at the shaft material material dropping position B or all of the shaft material 3 a in the carry-in chute 11 can be discharged into the common bypass chute 22.
[0028]
On the other hand, the shaft material 3a accommodated in the material accommodation hole 18d of the material receptacle 18e is moved to the material delivery position C as the slider 18a is advanced by the pusher cylinder 19.
The material delivery position C is formed with a recess 18f in which the lower part of the shaft object material 3a falls, and the shaft object material 3a falls out of the material accommodation hole 18d when the shaft object material 3a falls into the recess 18f.
[0029]
Further, since the tip side of the material receiver 18e is formed in advance thinner than the depth of the recess 18f, when the slider 18a is retracted in a state where the shaft object material 3a falls into the recess 18f, the material receiver 18e becomes the upper end of the bearing material 3a. Thus, the slider 18a can be returned to the original position while the shaft article material 3a remains at the material transfer position C.
The shaft material 3a moved to the material delivery position C is clamped by a finger (not shown) of a feed bar 24 provided in the press main body 1 and is carried into the press main body 1 so as to be processed. Become.

The structure of the means 20 ', the lift means 25, etc. will be described with reference to FIGS.
[0031]
The carry-in chute 11 ′ for dropping the plate material 3 b onto the separating apparatus main body 10 is configured so that the lower surface of the plate material 3 b falls while being in sliding contact with the bottom surface of the carry-in chute 11 ′. The side is connected to the plate material bypass means 20 'via the shaft material delivery position C. The plate material bypass means 20 ′ has a bypass plate 20 d whose bottom surface is curved in an arc shape.
[0032]
The lower side of the bypass plate 20d is pivotally attached to the table 10b side of the separating apparatus body 10 by a pin 20e, and one end of a bypass cylinder 26 is connected to the lower surface of the upper side. By rotating the upper end side of the bypass plate 20d downward in the center, one plate material 3b falling on the carry-in chute 11 'or all the plate-materials 3b in the carry-in chute 11' are moved into the common bypass chute 22. Can be discharged.
[0033]
The plate material delivery position D is provided with a positioning means 27 such as a stopper for accurately stopping the plate material 3b dropped from the carry-in chute 11 'on the plate material delivery D.
The plate material delivery position D is provided with lift means 25 for lifting the plate material 3b to a height at which the fingers of the feed bar 24 can be clamped.
[0034]
The lift means 25 has a lift bar 25 a provided below the plate material delivery position D.
The lift rod 25a is connected to the tip of a piston rod 28a of a lift cylinder 28 provided on the separating apparatus main body 10 side. The lift rod 25a is movable up and down by the lift cylinder 28, and above the lift rod 25a is a spring. A cylinder 25b is provided.
The upper end of the spring cylinder 25b is attached to the slide 1b of the press body 1 so as to be substantially vertical, and moves up and down together with the slide 1b. The spring 25c is moved downward by the spring 25c. A piston rod 25d urged toward is projected.
[0035]
Then, the plate material 3b is attached between the pad 25e attached to the tip of the piston rod 25d and the lift rod 25a, and the plate material 3b is lifted to such a height that the fingers of the feed bar 24 can be clamped. It has become.
[0036]
A full work detecting means 13 for detecting whether or not the plate material 3b is in the full state in the carry-in chute 11 'at the time of cold forging is provided at the upstream end side of the carry-in chute 11', and at the downstream side during the warm-forging A full work detection means 14 for detecting the plate material 3b is installed. At the plate material delivery position D, a temperature detection means 15 for detecting the temperature of the plate material 3b during warm forging, and a plate during cold forging. Material detecting means 16 for detecting the presence or absence of the material 3b is installed.
[0037]
Next, the operation of the material separating apparatus configured as described above will be described.
When the shaft article material 3a is separated and supplied to the press main body 1, a carry-in chute 11 for the shaft article material 3a is mounted on the support base 10a as shown in FIGS.
At this time, since various detection means 13 and 14 are attached to the carry-in chute 11 in advance, adjustment after the carry-in chute 11 is attached is not necessary.
[0038]
Next, the shaft material 3 a heated to a predetermined temperature by the heating furnace 6 is conveyed to the carry-in chute 11 by the carry-in conveyor 4 and is put into the carry-in chute 11.
The shaft object material 3a thrown into the carry-in chute 11 continuously falls in the carry-in chute 11 and reaches the shaft object material fall position B.
Then, the shaft material 3a that has reached the shaft material drop position B is moved to the shaft material transfer position C by the slider 18a of the pusher means 18 that is operated in synchronization with the operation of the press body 1, and is provided at the shaft material transfer position C. In the recessed portion 18f.
[0039]
Thereafter, when the slider 18a returns to the original position, the slider 18a is clamped by the fingers of the feed bar 24 that operates in synchronism with the operation of the press main body 1, and is carried into the press main body 1 for processing in the press main body 1.
[0040]
On the other hand, when the temperature detecting means 15 detects that the temperature of the shaft material 3a that has reached the shaft material falling position B is lower than the predetermined temperature, the bypass cylinder 21 of the bypass means 20 advances the bypass plate 20a, The bypass hole 20b opened in the bypass plate 20a is moved to the shaft object material dropping position B.
As a result, the shaft material 3a having a lowered temperature can be dropped into the common bypass chute 22 from the bypass hole 20b and discharged from the line.
[0041]
Further, when the predetermined number of processings are completed and the work is finished or the next material 3 is processed, the bypass plate 20a is advanced by the bypass cylinder 21 and the bypass hole 20b is moved to the shaft object material dropping position B. .
As a result, all of the shaft material 3a remaining in the carry-in chute 11 can be discharged into the common bypass chute 22, so there is no need to manually discharge the shaft material 3a.
[0042]
The above is the case where the shaft material 3a is separated and supplied into the press body 1. Next, the operation when the plate material 3b is separated and supplied into the press body 1 will be described.
In separating the plate material 3b, the carry-in chute 11 is replaced with a carry-in chute 11 'for the plate material 3b.
At this time, since the carry-in chutes 11 and 11 ′ need only be exchanged for a short distance connecting the carry-in conveyor 4 and the separation device main body 10, it is not necessary to lift and exchange them with a crane or the like. In addition, since various detection means 13 and 14 are attached to the carry-in conveyor 11 'in an adjusted state in advance, adjustment after the carry-in chute 11' is not required.
[0043]
Next, when the plate material 3b is supplied to the carry-in conveyor 4 by the parts feeder 7, the plate material 3b is thrown into the carry-in chute 11 'by the carry-in conveyor 4 and continuously falls in the carry-in chute 11'. The board material delivery position D is reached.
Then, the plate material 3b that has reached the plate material delivery position D is positioned by the positioning means 27, and is then clamped between the pad 25e and the lift rod 25a that descend as the slide 1b of the press body 1 descends.
[0044]
Thereafter, as the slide 1b rises, the lift rod 25a is raised by the lift cylinder 28, and the plate material 3b attached between the pad 25e and the lift rod 25a is lifted to a position where it can be clamped by the fingers of the feed bar 24. After being clamped by the fingers of the feed bar 24 that operates in synchronization with the operation of the press main body 1, it is carried into the press main body 1 by the feed bar 24 and used for processing in the press main body 1.
[0045]
On the other hand, when the temperature detecting means 15 detects that the temperature of the plate material 3b that has reached the plate material delivery position D is lower than the predetermined temperature, the bypass cylinder 26 moves down the bypass plate 20d around the pin 20e. Turn to.
As a result, the plate material 3b having a lowered temperature slides down on the bypass plate 20d and is discharged from the line.
Further, even when the predetermined number of processings are completed and the work is finished or the process proceeds to the processing of the next material 3, the bypass plate 20 d is rotated downward by the bypass cylinder 26 to remain in the carry-in chute 11. All of the plate material 3b to be discharged can be discharged into the common bypass chute 22.
