First, with reference to FIG. 2, a first embodiment of a scrap scrap collecting device remaining after cutting a thick plate product according to the present invention will be described.

First embodiment

2 is a view schematically showing a device for collecting scrap remaining after cutting a thick plate product according to a first embodiment of the present invention.

Referring to FIG. 2, the remaining scrap separation collection apparatus after cutting a thick plate product according to the first embodiment of the present invention includes a scrap chute hole 110 and a scrap chute 110 formed on a bed of a gas cutter. It consists of a configuration including a scrap storage unit 130 for storing and storing the heavy plate scrap carried by the scrap conveying unit 120 and the scrap conveying unit 120 to load and transport the falling back plate scrap.

The scrap chute 110 is perpendicular to the bed 10 so that the heavy plate scrap r remaining on the bed 10 can be dropped below the bed 10 after cutting the thick plate product of the gas cutting unit. Plurality is formed through.

However, the scrap chute hole 110 is formed to vertically penetrate the surface of the bed 10, and may have a transverse long hole shape in which a plurality of pieces are spaced at regular intervals with a length corresponding to the width of the bed 10. . However, the specific shape of the scrap chute 110 is only in accordance with the preferred embodiment, the present invention does not necessarily need to be limited to the specific shape of the scrap chute 110.

Therefore, any structure and shape in which the thick plate scrap remaining on the bed 10 of the gas cutter can fall to the bottom of the bed 10 may be considered to be within the scope of the present invention.

As can be seen through Figure 2, the width (d) size of the scrap chute hole 110 should be formed in a larger range than the thickness (t) of the thick plate scrap (r), even if the thick plate product (S) is to fall As such, the size range is an important consideration in the design of the device.

The scrap conveyance unit 120 is formed to have a transport section corresponding to the length section of the bed 10 at the lower side of the bed 10, and loads the thick plate scrap (r) dropped through the scrap chute hole 110 It is responsible for carrying.

To this end, the scrap conveying unit 120, the plurality of feed rollers 122 and the outer edges of the plurality of feed rollers 122 are arranged to be spaced apart below the bed 10 corresponding to the length section of the bed (10) It is formed so as to be in contact friction with each other and wound around the feed belt 124 linearly moving in conjunction with the rotational drive of the plurality of feed rollers 122, and a rotary drive unit provided to provide a rotational drive force to the feed rollers 122 ( 126).

Here, the rotation drive unit 126 is made of a structure in which at least one feed roller and the drive shaft of the plurality of feed rollers 122 are connected, it is possible to use a servo motor in which the rotation speed and torque is controlled according to the electrical signal.

In addition, an operation switch 150 electrically connected to the rotation driver 126 may be further provided to input a user's command to the electrical signal to be applied to the rotation driver 126.

On the operation switch 150, a display unit 152 capable of implementing visual monitoring may be further provided in order to improve user convenience of operation, and in addition, a keypad capable of receiving various operation commands from a user. 154 is preferably formed.

In addition, although not separately illustrated, a damper member may be interposed in the scrap conveyance unit 120 to attenuate the vibration due to the impact load with the rear plate scrap dropped onto the conveyance belt.

The scrap storage unit 130 is provided in the lower portion of the front of the transfer section of the scrap transfer unit 120 serves to store and store the rear plate scrap (r) carried by the scrap transfer unit 120.

However, since the heavy plate scrap (r) is dropped into the scrap storage unit 130 by the scrap transfer unit 120 is introduced, there is a risk that loud noise and various safety accidents are caused during work.

In order to prevent this problem, the scrap storage unit 130, a sliding guide (132) may be further provided.

The sliding guide 132 serves to transfer the thick plate scraps r dropped into the scrap storage unit 130 at the end of the transfer section of the scrap transfer unit 120 in a sliding manner, and thus, the heavy plate scraps r of weight. This suppresses the noise when the drop is put, and also provides a function to prevent various safety accidents.

Thus, according to the present inventors scrap scraping device after cutting the thick plate product of the present invention, the scrap remaining during the process of cutting the blade to the product size in the thick plate factory, dropping the scrap to the lower side of the gas cutter after falling quickly, By adopting a method of transporting and storing up to the storage box, there is an advantageous technical effect that can improve the productivity of the product by reducing the investment of additional manpower and equipment (eg crane).

Furthermore, in order to automate the operation of the first embodiment of the present invention, to introduce the second embodiment of the present invention, which includes all the configurations of the above-described first embodiment, and further includes an additional configuration for active control. Shall be.

Second Embodiment

3 is a view schematically showing a device for collecting scrap remaining after cutting a thick plate product according to a second embodiment of the present invention.

Referring to FIG. 3, in addition to the configuration of the first embodiment of the present invention described above with reference to FIG. 2, a signal detected by the thick plate scrap drop detector 160 and the thick plate scrap drop detector 160 is additionally input. Received, the scrap transfer unit 120 is made of a configuration that further includes a control unit 170 for controlling the drive.

Here, the rest of the configuration except for the heavy plate scrap drop detection unit 160 and the control unit 170 is the same as the configuration of the first embodiment of the present invention as described above, unnecessary redundant description will be omitted.

The thick plate scrap drop detection unit 160 is disposed in the space between the scrap chute hole 110 and the scrap transfer unit 120, and the presence or absence of the thick plate scrap r to be dropped from the scrap chute hole 110 is present. It plays a role in detecting it.

That is, the thick plate scrap drop detection unit 160 may use a non-contact proximity sensor of light or infrared scanning.

If the rear plate scrap drop detection unit 160 detects the rear plate scrap (r) falling through the scrap chute hole 110, the control unit 170 applies a driving command to the rotational drive unit 126 side.

In other words, the control unit 170 receives the rear plate scrap (r) drop detection signal detected by the rear plate scrap drop detection unit 160, and operates the rotary drive unit 126, which is the driving source of the scrap transfer unit, to operate the control unit, Unnecessary energy waste can be reduced.

Also in the case of the second embodiment of the present invention, an operation switch (150 of FIG. 2) for receiving a command of a separate user may be provided.

Thus, according to the present inventors scrap scraping device after cutting the thick plate product of the present invention, the scrap remaining during the process of cutting the blade to the product size in the thick plate factory, dropping the scrap to the lower side of the gas cutter after falling quickly, By adopting a method of transporting and storing stocks up to the storage box, product productivity can be improved by saving extra manpower and equipment (eg crane) investment.

It has been described above for the scrap scrap collection device remaining after cutting the thick plate product according to the present invention.

It is to be understood that the above-described embodiments are illustrative in all aspects and should not be construed as limiting, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
