Description

Apparatus for cutting styrofoam

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a styrofoam cutting apparatus, and more particularly, to a technique capable of improving a cutting efficiency of a styrofoam by improving a flow structure when a styrofoam is cut longitudinally and then cut in a thickness direction.

In general, styrofoam is used as an insulating material, a soundproofing material, a cushioning material, and is called expanded polystyrene, expanded styrene, styropor, and the like.

Such styrofoam is a polymer of styrene and is a colorless and transparent thermoplastic material, which is softened at 100 ° C or higher, becomes a viscous liquid at about 185 ° C, and has strong acid, alkali, oil and alcohol properties.

Styrofoam is produced by injecting hydrocarbon gas such as pentane or butane into a polystyrene resin and then foaming it with steam. 98% of the volume is air, and the remaining 2% is composed of resin.

Styrofoam produced in this manner is cut and cut to a certain size and needs to be cut to an appropriate size.

In the styrofoam cutting process, the styrofoam is first conveyed in the direction of the cutter by a conveyor or the like. Styrofoam arriving at the vertical cutter is cut in the thickness direction perpendicular to the process of passing the vertical wire through which heat is generated.

The plurality of styrofoams cut in the thickness direction are continuously conveyed by the conveyor to reach the horizontal cutter. The styrofoam which has reached the horizontal cutter is cut in the longitudinal direction while the leading styrofoams are first passed through the vertical wire of the horizontal cutter, and then the styrofoam in the middle portion is conveyed by the conveyor so that the styrofoams are cut while passing through the vertical wire, .

However, the conventional styrofoam cutting process has the following problems.

That is, when the styrofoam is first cut in the longitudinal direction by the horizontal cutter passing through the vertical cutter, the horizontal cutter cuts the styrofoam in the longitudinal direction, and the intermediate portion and the rear end portion are waiting while the tip portion is cut, When the conveyor is further driven, the cut end is discharged, and the intermediate part is transported to the position and horizontally cut. Further, when the conveyor is further driven after the middle part is cut, the intermediate part is discharged and the rear end is moved to the position and cut As a result, the cutting process for the styrofoam is performed sequentially in a single line, which results in a reduction in the efficiency of the cutting process.

In addition, if a malfunction occurs in the cutting operation of the tip end portion, the middle portion and the rear end portion are stopped because of the serial method, which results in a further decrease in efficiency.

Hereinafter, a styrofoam cutting apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, the styrofoam cutting apparatus proposed by the present invention includes an X-axis conveyor 1, 2, 5 for conveying styrofoam in the X-axis direction;

A vertical cutter 7 disposed on the X-axis conveyor 1, 2, 5 to cut the styrofoam in the vertical direction;

A plurality of Y-axis conveyors (9, 11) arranged in the Y-axis direction with respect to the X-axis conveyors (1,2, 5) for switching and transferring the styrofoam conveyed in the X-axis direction in the Y-axis direction;

Axis conveyors 1, 2 and 5 and a plurality of Y-axis conveyors 9 and 11 to transfer the styrofoam on the X-axis conveyors 1, 2 and 5 to the Y-axis conveyors 9 and 11 A plurality of aligners (13, 15); And

And a plurality of horizontal cutters (17, 19) arranged on the Y-axis conveyors (9, 11) for cutting the conveyed styrofoam in the longitudinal direction.

In the styrofoam cutting apparatus having such a structure,

An X-axis conveyor (1, 2, 5) is arranged at the line entrance and comprises a first conveyor (1) for conveying the styrofoam to the vertical cutter (7); A conveyor 2 disposed below the vertical cutter 7 for discharging vertically cut styrofoam; And a second conveyor 5 disposed on the exit side of the vertical cutter 7 for discharging the vertically cut styrofoam.

The first conveyor 1 conveys the styrofoam to the vertical cutter 7 as a conveyor in a conventional manner using a plurality of conveying rollers 35 and a chain.

The vertical cutter 7 cuts the transferred styrofoam vertically and vertically. The vertical cutter 7 includes a heat ray fixing frame 21; A vertical frame (25) for supporting the hot wire fixing frame (21) so as to move up and down; A plurality of support rollers 23 arranged on the hot wire fixing frame 21; A vertical wire (W1) connected to the support roller (23) and cutting vertically the styrofoam by high temperature heat; A vertical ascending / descending section 27 disposed in the vertical frame 25 for vertically cutting the styrofoam by vertically moving the hot wire fixing frame 21 up and down; And a plurality of feed rollers 35 for feeding the styrofoam.

In the vertical cutter 7 having such a structure, the heat ray fixing frame 21 has a rectangular frame shape and a plurality of support rollers 23 are disposed inside the vertical frame. The support roller 23 corresponds to the support roller 23 opposed to the inside of the heat ray fixing frame 21, and the vertical wires W1 are connected to each other.

Therefore, a plurality of vertical wires W1 can be disposed across the inside of the heat ray fixing frame 21. [

The vertical wire W1 is connected to a power supply unit (not shown) to generate heat at a high temperature upon power supply, thereby cutting the styrofoam.

The vertical ascending / descending section 27 means an LM guide mounted on one side of the vertical frame 25. [ That is, the LM guide is a conventional LM guide, in which the rail is arranged in the vertical direction to the vertical frame 25, and the LM block in which the bearing and the ball screw are mounted is transportably mounted. The LM block is mounted on the hot-wire fixing frame 21 so that the hot-wire fixing frame 21 can vertically move up and down along the vertical frame 25.

Therefore, when the styrofoam is cut in the vertical direction, the control unit 6 controls the LM guide to lower the wire W1 so that the hot wire W1 descends from the top of the styrofoam and is cut by heat.

At this time, since the plurality of vertical wires W1 are spaced apart from each other by a predetermined distance, the styrofoam is also cut into a plurality of strips.

As described above, the styrofoam cut into various parts by the vertical cutter 7 is transported in the X-axis direction by the X-axis conveyors 1,

At this time, the styrofoam cut into a plurality of pieces reaches the position to be conveyed along the second conveyor 5 in the X-axis direction and to be conveyed to the third conveyor 9 and the fourth conveyor 11, which will be described later.

For example, a part of styrofoam cut into a plurality of pieces reaches a position where it can be converted and conveyed to a fourth conveyor 11, and the remaining styrofoam is converted to a third conveyor 9, Lt; / RTI >

Alternatively, when the entire length of the styrofoam is small, the entirety of the vertically cut styrofoam reaches the position where it can be switched and transferred to the fourth conveyor 11, and the entire vertically cut styrofoam later is transferred to the third conveyor 9 To reach the position where it can be.

Accordingly, the styrofoam conveyed in the X-axis direction along the second conveying conveyor 5 can be simultaneously conveyed to the horizontal cutter by the third and fourth conveyors 9 and 11 arranged in parallel.

At this time, it is possible to convey the styrofoam to a predetermined position on the second conveying conveyor 5 by the conveying roller 35 controlled by the control unit 6. [

That is, the second conveying conveyor 5 is divided into a plurality of zones, each zone comprising a plurality of conveying rollers 35 rotatably mounted on the frame; A chain 33 for connecting the sprockets of the conveying rollers 35 to each other; A drive chain (32) for rotating one of the plurality of sprockets; And a motor 35 for rotating the drive chain 32.

The motor 35 is connected to the control unit 6 so that the rotation speed and the speed can be adjusted.

Therefore, the control unit 6 controls the rotation of the conveying roller 35 by controlling the motor 35 to appropriately control the conveying position of the styrofoam.

For example, rotating the conveying rollers 35 of the first and second zone modes of the second conveying conveyor 5 allows the styrofoam to be conveyed to the tip of the second conveying conveyor 5, And the second zone is not rotated, the styrofoam reaches the position of the third conveyor 9 only.

When the styrofoam reaches the second conveying conveyor 5 in this manner, it can be switched and conveyed to the third conveyor 9 and the fourth conveyor 11 by the plurality of aligners 13 and 15.

The plurality of aligners (13, 15) include first and second aligners (39, 41) rotatably arranged between the second conveyor (5) and the third conveyor (9) to align the styrofoam; And third and fourth aligners 43 and 45 rotatably disposed between the second conveyor 5 and the fourth conveyor 11 to align the styrofoam.

First, in the first and second aligners 39 and 41,

The first aligner 39 includes a plurality of rotation bars 47 and 49 each having a vertical bar 49 and a horizontal bar 47, respectively, and having a "?" A rotary shaft (51) in which a plurality of rotary bars (47, 49) are fixedly arranged; And a cylinder assembly 53 for rotating the rotary shaft 51.

In the first aligner 39 having such a structure, the vertical bar 49 and the horizontal bar 47 are extended at a predetermined angle, for example, at an angle of 90 degrees. The plurality of rotary bars 47, 49 are disposed between the conveying rollers 35 of the second conveyor 5.

When the rotary bars 47 and 49 are turned in the direction opposite to the first horizontal cutter 17, the horizontal bar 47 is disposed between the conveying rollers 35, And is positioned lower than the upper surface.

Therefore, when the styrofoam is conveyed by the second conveyor 5, the styrofoam can be conveyed without interfering with the horizontal bar 47.

An arm 54 is fixedly connected to the rotating shaft 51 and the cylinder assembly 53 is connected to the end of the arm 54. [

Therefore, when the piston of the cylinder assembly 53 advances upward, the piston rotates counterclockwise, which is the direction of the first horizontal cutter 17, so that the rotary shaft 51 also rotates to rotate the horizontal bar 47, Is in an upright state.

On the other hand, the upright vertical bar 49 is rotated in the direction of the first horizontal cutter 17 to lie horizontally in the buffer zone B provided between the first aligner 39 and the second aligner 41 do.

The second aligner 41 also has a structure similar to that of the first aligner 39. That is, the second aligner 41 includes a plurality of rotation bars 55 and 57 each having a vertical bar 57 and a horizontal bar 55, respectively. A rotary shaft (61) in which a plurality of rotary bars (55, 57) are fixedly arranged; And a cylinder assembly 59 for rotating the rotary shaft 61.

Since the structure of the second aligner 41 is similar to that of the first aligner 39, a duplicate description will be omitted.

The rotation bars 55 and 57 of the second aligner 41 are disposed at positions shifted from the rotation bars 47 and 49 of the first aligner 39, Therefore, when the first aligner 39 and the second aligner 41 are rotated with respect to each other, they can rotate without being interfered with each other.

The third and fourth aligners 43 and 45 are disposed between the fourth conveyor 11 and the second conveyor 5 to convey the styrofoam.

Since the third and fourth aligners 43 and 45 have the same structure as the first and second aligners 39 and 41, the detailed description will be omitted.

The process of transferring styrofoam from the second conveyor 5 to the third conveyor 9 by means of the first and second aligners 39 and 41 will now be described.

First, as shown in Fig. 6 (a), the first aligner 39 is rotated in the direction opposite to the first horizontal cutter 7, so that the horizontal bar 47 is pushed by the plurality of conveying rollers 5 of the second conveyor 5, And the upper surface of the horizontal bar 47 is positioned below the upper surface of the conveying roller 35. [

The vertical bar 49 is in an upright position.

In this state, the cylinder assembly 53 is driven to advance the piston upward in the diagonal direction, thereby rotating the arm 54 and the rotary shaft 51.

As the rotary shaft 51 rotates, the horizontal bar 47 is erected and the vertical bar 49 is laid down in the buffer zone B.

At this time, the styrofoam placed on the horizontal bar 47 is rotated as the horizontal bar 47 and placed on the vertical bar 49.

6 (b), the styrofoam reaches the buffer zone B in a state of being placed on the vertical bar 49 and is seated in the horizontal state. At this time, the horizontal bar 49 of the second aligner 41 55 are laid flat in the buffer zone B.

Therefore, when the vertical bar 49 of the first aligner 39 is laid horizontally in the buffer zone B, it is laid down without interfering with the horizontal bar 55 of the second aligner 41.

As a result, the vertical bar 49 of the first aligner 39 and the horizontal bar 55 of the second aligner 41 are stacked on the bottom surface of the styrofoam.

6 (c), when the cylinder advances upward along the oblique direction by driving the cylinder assembly 59 of the second aligner 41, the horizontal bar of the buffer zone B (55) stands upright.

Thus, the second aligner 41 picks up styrofoam from the first aligner 39 in the buffer zone B and places it on the third conveyor 9.

As a result, the styrofoam on the second conveyor 5 is rotated 180 degrees and is placed on the third conveyor 9 in a state of being turned upside down.

Then, the third conveyor 9 conveys the styrofoam toward the first horizontal cutter 17.

In the above description, the process of transferring styrofoam by the first and second aligners 39 and 41 has been described. Since the process of transferring the styrofoam by the third and fourth aligners 43 and 45 is the same, the following description is omitted.

The third and fourth conveyors 9 and 11 mean a conventional conveyor composed of a plurality of conveying rollers, a sprocket, a chain, and a motor.

Then, the styrofoam is conveyed by the third and fourth conveyors 9 and 11 to be conveyed to the plurality of horizontal cutters 17 and 19, and is cut in the horizontal direction and separated into several layers.

These plurality of horizontal cutters (17, 19) comprise a first horizontal cutter (17) arranged on the third conveyor (9); And a second horizontal cutter (19) disposed on the fourth conveyor (11).

First, the first horizontal cutter 17 will be described in detail. A horizontal wire (W2) which is wired in the transverse direction inside the frame (61) and cuts the styrofoam by high temperature heat; And a pressure roller 63 disposed on the inner upper side of the frame 61 to prevent the styrofoam from being pressed upward by the upper part when cutting the styrofoam.

One or more of the horizontal wires W2 may be disposed, and the intervals of the horizontal wires W2 may be appropriately adjusted according to the cutting standard of the styrofoam.

When the styrofoam placed on the third conveyor 9 enters the first horizontal cutter 17 by the conveying roller, the pressing roller 63 contacts the upper surface of the styrofoam and presses it downward.

Thus, the styrofoam is brought into contact with the horizontal wire W2 in an unexpected state, and is pressed forward by the rotation of the conveying roller of the third conveyor 9, whereby the styrofoam can be cut from the leading edge.

In this way, the styrofoam can be cut and separated into multiple layers in the process of passing through the plurality of horizontally arranged horizontal wires W2.

The process of cutting the styrofoam conveyed to the second horizontal cutter 19 by the fourth conveyor 11 is the same as that of the second horizontal cutter 19, and a detailed description thereof will be omitted.

As described above, the styrofoam separated into a plurality of pieces by the vertical cutter 7 is conveyed in the X-axis direction along the second conveyor 5, and the third and fourth conveyors 9, 11 arranged in parallel, Axis direction and cut by the first and second horizontal cutters 17 and 19, respectively.

As described above, the styrofoam conveyed in one line in the X-axis direction is conveyed in the Y-axis direction by a plurality of conveyors arranged in parallel and cut horizontally, thereby improving the cutting efficiency.
