Description

Scrap Iron Compression Device Using Locking "

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scraper-type compression apparatus using locking, and more particularly to a scraper-type compression apparatus using locking, which is made into a compression-molded product having a predetermined size, such as scrap, punch rice, scrap .

Waste scrap generated from industrial sites and ordinary households is collected by a collection company and then compressed into a cylinder or a polygon (rectangle) shape of a certain size to be made into a scrap iron solid, and the scrap metal solid material thus produced is carried to be recycled.

However, according to the conventional scrap iron compressor, there is a problem in that a small and flat sized scrap iron remains in the waste scrap metal receiving part during the compression of the scrap metal, and the small gap formed between the moving part compressing the scrap metal and the inner wall of the receiving part frequently And therefore, there is a problem that the moving part fails to operate properly and thus fails to provide sufficient pressure for compressing the scrap iron.

 As a conventional technique for solving such a problem, there are a gyroscopic compressor shown in, for example, Japanese Laid-Open Patent Publication No. 2002-0063464 and Japanese Laid-Open Patent Publication No. 2012-0061790. According to the gyroscope compressor shown in these documents, A problem is solved by removing residual scrap iron by using high-pressure compressed air or by forming grooves having an appropriate size so as to be able to move properly even if flat scrap iron is introduced into the bottom of the moving part.

However, in the method of removing the scrap iron by using compressed air, since the worker must periodically remove the scrap iron, the efficiency of the compression work of the scrap iron is lowered. When the groove is formed on the bottom surface of the moving part, So that it is difficult to achieve the object of preventing the movement of the moving part through the groove from being deteriorated.

Meanwhile, in the case of a conventional hired-steel compressor, the size (length) of a compression-molded product to be compressed differs depending on the type thereof. In order to reuse the compression-molded product in this case, In this way, there is a need to use a cutter separately from the scraper compressor to cut the compacted product again.

Therefore, in the case of a compression molding machine having a cutting function as described above, the scraper compressor disclosed in the publication No. 2013-0091884 is configured to be cut to a required size in the process of discharging the compression molding. Although it is advantageous to be able to cut a compression molded product, if a compression molded product is cut according to the standard, a small compacted product which does not conform to the standard is left, and the compacted product is re- There is a hassle.

Therefore, it is required to develop a scraper-type compression apparatus using locking which can easily remove the scrap iron remaining in the inside of the receiving portion of the scraper compressor and compress the small sized compression molding article without cutting.

The compressor 40 which is rotatably installed inside the main frame 10 and compresses the scrap iron introduced through the input hopper 20 is shown in Figs. 5, 6 and 7 (a), 7 (b) A compressor housing 41 having a predetermined length in which both sides are opened as shown in the figure and a receiving portion H is formed therein and an extension protrusion 41A is formed on both ends of the compressor housing 41 and an extension protrusion A sliding plate 43 sliding along the receiving portion H by a length adjusting unit 42 having a size corresponding to the receiving portion H, A pressurizing unit 44 in which a pressure piston 44B is installed to penetrate the sliding plate 43 so that the cylinder 42A is installed at one side of the sliding plate 43 and is led into and out of the receiving portion H, A pressure plate 45 provided at the front end of the accommodating portion H for pressurizing and compressing the scrap heap accommodated in the accommodating portion H, , As provided on the other end of the compressor housing 41, cover 46 covering the other end of the compressor housing (41); And a lid opening / closing unit 47 which is provided to connect the bottom of the compressor housing 41 and the lid 46 and opens and closes the lid 46 by a pull-in / out operation.

At this time, on both sides of the compressor housing 41, a shaft mounting hole 41B for inserting the rotating shaft 13 is provided. Bearing (not shown) is provided inside the shaft mounting hole 41B, and the compressor housing A plurality of guide protrusions G are formed along the lengths of the inner side surface and the outer side surface.

The sliding plate 43 and the pressure plate 45 can be stably moved along the receiving portion H by the guide protrusion G and the pressure generated in the process of compressing the scrap iron by the compressor housing 41 .

The cylinder 42A is fixed to the extending projection 41A and one end of the piston 42B is fixed to one side face of the sliding plate 43. As a result, The sliding plate 43 appropriately moves along the accommodating portion H by the pulling-out operation of the piston 42B, thereby adjusting the size of the space (the length of the compression molding) in which the scrap iron is received. At this time, the length adjusting unit 42 may be structured to be operated by a motor and a screw shaft which is rotated by a motor.

7 (b), the pressing plate 45 is formed with a concave portion in the middle of one side facing the lung scrap, so that when the lung scrap iron contained in the receiving portion H is compressed, The gap between the pressure plate 45 and the inner surface of the receiving portion H is significantly reduced as a result of being flattened while being guided to the middle portion of the pressure plate 45 relatively to the outside.

The tip of the piston 44B is connected directly to the center portion of the pressure plate 45 so that the pressure acting on the pressure unit 44 can be evenly transmitted to the pressure plate 45, (Not shown) arranged in a plurality of radial directions.

The cover 46 is assembled to be openable and closable by being coupled with a hinge engaging part 46B provided at a lower side of the lid 46 with a hinge coupling part at the other end bottom surface of the compressor housing 41, An inclined face portion 46A extending obliquely in a direction opposite to the compressor housing 41 is formed along the lower end of the lid 46. The piston 47B of the lid opening and closing unit 47 is connected to the inclined face portion 46A, And the cylinder 47A of the lid opening / closing unit 47 is connected to the bottom surface of the compressor housing 41 so that the inclined surface portion 46A of the lid 46 is pulled or pushed by the pulling-out operation of the piston 47B The lid 46 is opened and closed.

8 and 9, the compressor 40 having the above-described structure is configured such that the sliding plate 43 slides in the receiving portion H by the length adjusting unit 42, And then pressurizing the scrap iron by using the pressure plate 45. Thereby, it is not necessary to post-process the compression-molded product by using a cutter or the like.

The locking unit 50 selectively locks and supports one side of the compressor 40.

The pressure acting on the pressure plate 45 at the time of compressing the scrap iron in the compressor is largely applied to the lid 46 along the scrap iron so that the lid 46 is kept in a stable closed state by a separate fixed clamp And the lid is stably closed by controlling the fixing clamp.

However, in the above case, a large shearing force is repeatedly generated in the fixed clamp, which causes deformation of the fixed clamp and fatigue failure.

Accordingly, the present invention is configured to receive the force acting on the platen 45 using the locking unit 50 to support the lid 46. [

When the lid 46 is supported by the locking unit 50 as described above, the lid 46 can be stably supported even with a smaller pressure than that of using the lid opening / closing unit 47 to support the lid 46 And the large load is not applied to the hinge engaging portion 46B, consequently, deformation and breakage of the lid 46 are prevented.

The locking unit 50 includes a hydraulic cylinder having a capacity corresponding to the pressing unit 44 and a supporting plate 52. The locking unit 50 is configured to maintain the lid 46 in a stable closed state A pair of locking brackets 51 protruding from the lid 46 and having a locking hole 51A and a pair of locking brackets 51 as the lid 46 is closed, A fixing bracket 52 having a fixing hole 52A corresponding to the locking hole 51A and provided in the compressor housing 41 and a fixing bracket 52 provided between the fixing bracket 52 and the locking hole 51A of the locking bracket 51, And a bi-directional rod cylinder (53) passing through the fixed hole (52A) of the fixed bracket (52).

That is, after the lid 46 is closed, the locking unit 50 is driven so that the bidirectional rod cylinder 53 is driven and the rod installed in the inside is drawn out according to the operation of the bidirectional rod cylinder 53, The locking bracket 51 and the fixing bracket 52 are fixed through the locking hole 51A of the locking bracket 51 and the fixing hole 52A of the fixing bracket 52. [

A controller (not shown) for controlling the operation of the compressor 40 and the locking unit 50 includes a wired or wireless control means so that the operator can control it remotely, (50) when the compressor (40) is rotated, when the compressor (40) flows into the compressor (40) through the compressor (20) (40) is operated in a state of being locked by the locking unit (50) to compress the scrap iron. When the compression of the scrap iron is completed, the locking unit (50) The compressor 40 is rotated again and the compressor 40 is pushed outward by the compressor 40 to be discharged to the outside through the discharge guide 30 when the compressor 40 is rotated again.

According to the structure-improved scrap iron compressor of the present invention configured as above, when the lid 46 of the compressor 40 is opened as shown in Fig. 10, the open side (the direction in which the lid is installed) In this state, an appropriate amount of scrap iron is introduced into the accommodating portion H through the input hopper 20, and a sensing sensor and a weight sensor for sensing the amount of scrap of the scrap metal may be provided.

After the appropriate amount of the scrap iron is received in the accommodating portion H as described above, the compressor 40 is rotated so as to be horizontal, and the lid 46 is closed to cover the accommodating portion H.

11, the locking unit 50 controls the locking of the outer surface of the lid 46, and in this state, the pressing plate 45 is used to lock the receiving portion H And compresses the received scrap iron 1.

12, the locking of the lid 46 by the bidirectional rod cylinder 53 is released and the lid 46 is opened so that the opening portion of the compressor 40 is closed by the discharge guide 30).

Then, the compression mold 1 'is pushed out of the accommodating portion H by the pressure plate 45, and after the compression mold 1' is discharged, the above process is repeated again.

At this time, a conveying conveyor 2 or the like is positioned at one side of the discharge guide 30 so that the press molded product 1 'is moved to the conveying conveyor 2 along the inclined surface of the discharge guide 30, And conveyed by the conveyor 2.

In this case, the opening portion of the compressor 40 can be easily removed by gravity by further lowering the opening portion of the compressor 40 toward the bottom of the main frame 10, A collection box (not shown) for collecting waste scrap iron may be further provided in the inner lower portion of the main frame 10.

Further, a vibration generator (not shown) may be further provided to apply a vibration to the compressor 40. When the opening of the compressor 40 is lowered toward the bottom of the main frame 10, It is possible to more easily remove the remaining scrap iron by the excitation of the compressor 40 through the valve.

As described above, according to the present invention, since the size of the compression-molded product can be appropriately adjusted to a required size, post-processing such as a cutter is not required, and even when a large pressure acting on the pressure plate is applied, And it is possible to easily remove the scrap iron remaining in the inside of the compressor as needed.
