The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

FIG. 1 is a perspective view showing the construction of a resin-finished product burr removing apparatus 100 according to the present invention, and FIGS. 2 to 4 are illustrations showing an operation process of a resin-finished product burr removing apparatus 100.

As shown in the drawings, the resin-finished product burr removing apparatus 100 of the present invention burns burrs (A in FIG. 1) irregularly generated in the edge region at the time of processing a resin-finished product using heat generated from an infrared lamp, . Thus, the surface of the rim of the resin-finished product can be smoothly processed.

Here, for convenience of explanation, the detailed description of the present invention will be described by taking a burr of the substrate tray 10, which is an example of a resin processed product, as an example. However, this is merely an example, and the resin finished product deburring device 100 of the present invention can also be used for deburring of trays, sheets, containers, and the like for other uses made of plastic resin.

The apparatus for removing burrs 100 of the present invention comprises a first processed product transferring section 110 for transferring the long axis 13 of the substrate tray 10 forward and a second processed product transferring section 110 for transferring the first processed product to one side of the transferring section 110 A first lamp part 120 and 120a disposed in a direction perpendicular to the end of the transfer part 110 to remove the burrs of the short axis 15 of the substrate tray 10, A second workpiece is transferred between the transfer section 110 and the transfer section 150 so that the first workpiece is transferred in the transfer direction of the substrate tray 10 A cooling section 140 for cooling the substrate tray 10 via the transfer section 110 for a predetermined period of time and a cooling section 140 for cooling the substrate tray 10 via the transfer section 110 at one side of the transfer section 150, A second ramp portion 160 and 160a arranged to remove the burrs of the long axis 13 of the substrate tray 10 and a control portion 170 for controlling the respective components according to input conditions.

The substrate tray 10 is formed in a rectangular shape. At this time, the resin processed product burr removing device 100 first removes the burr of the minor axis 15 of the substrate tray 10, and removes the burr of the major axis 13. Here, the long axis 13 and the short axis 15 are selected for convenience of explanation, and in the case of a finished product of a prismatic shape or a circular shape, the direction can be adjusted so that all the burrs of the whole rim can be removed.

In the present invention, the burrs of the minor axis 15 are removed first and the burrs of the major axis 13 are removed, but the order of removing the burrs may be changed.

The first processed product transfer unit 110 transfers the substrate tray 10 at a constant speed and allows the heat of the first ramps 120 and 120a to be applied to the substrate tray 10. The first processed product transfer unit 110 includes a first entry roller 111 through which the operator enters the substrate tray 10 and a second entry roller 111 provided at the end of the first entry roller 111 to automatically transfer the substrate tray 10 And a waiting roller 117 provided at a rear end of the first conveying chains 113 and 113 'and waiting for a predetermined time.

Here, the first processed product transfer section 110 is supported on the frame 180. [ The first entry roller 111 is idly rotatably coupled to the frame 180. A plurality of first entry rollers 111 are rotatably coupled to the frame 180. When the worker loads the substrate tray 10 on the top of the first entry roller 111, the first entrance roller 111 is rotated by the load and the substrate tray (not shown) 10 to the first conveyance chain 113, 113 '.

The first conveying chains 113 and 113 'automatically convey the substrate tray 10 by the conveying unit 110 a predetermined distance. The first transfer chains 113 and 113 'are coupled to the first chain drive roller 113a and the first chain driven roller 113b and are moved by the drive of the first chain drive unit 116. [

The first conveyance chains 113 and 113 'are provided with a pair of left and right sides. At this time, the distance between the first transport chains 113 and 113 'is adjusted to correspond to the width of the substrate tray 10 to be transported. When the operator adjusts the handle, the first transfer chain interval adjusting portion 115 moves the adjusting shaft having the threaded portion back and forth as the operator manipulates the handle, (113, 113 ').

Here, the moving speeds of the first transport chains 113 and 113 'are determined according to the control of the controller 170. [ The control unit 170 drives the first chain driving unit 116 according to the driving conditions inputted by the operator through the input unit (not shown) to adjust the feeding speed of the substrate tray 10.

The transfer speed of the substrate tray 10 of the first transfer chain 113, 113 'can be adjusted according to the thickness and the size of the substrate tray 10. For example, when the substrate tray 10 of a size of 392 mm * 243 mm with a thickness of 1.2 mm is transported, the first transport chain 113, 113 'is driven at a speed of 10 to 15 m per minute.

When the conveying speed of the first conveying chains 113 and 113 'is slow, the contact time between the substrate tray 10 and the first ramps 120 and 120a becomes long and the substrate tray 10 itself may be thermally deformed. Accordingly, the first conveyance chains 113 and 113 'are driven at a conveyance speed at which only burrs can be removed in a range where the substrate tray 10 itself is not thermally deformed.

The waiting roller 117 is disposed at the rear end of the first conveying chain 113, 113 '. The waiting roller 117 is also provided on the frame 180 for idle rotation. The substrate tray 10 conveyed along the first conveyance chains 113 and 113 'is moved to the waiting roller 117 by the conveying speed and conveyed to the end of the waiting roller 117 as shown in FIG.

The substrate tray 10 located at the waiting roller 117 in the edge area of the first processed product transferring part 110 and the second processed product transferring part 150 is supplied with the cool air C for a certain period of time by the cooling part 140 And cooled. Then, the second workpiece is pressed by the transfer switching unit 130 and moved to the transfer unit 150. [

The first ramps 120 and 120a irradiate infrared rays to the substrate tray 10 transported along the first transport chains 113 and 113 'to remove burrs formed on the short axis 15 of the substrate tray 10. A plurality of the first lamp units 120 and 120a are arranged alternately on the right and left sides of the frame 180. This is because when a plurality of first ramps 120 and 120a are disposed opposite to each other and simultaneously irradiating heat to both sides of the substrate tray 10, heat may be generated in the substrate tray itself as well as burrs.

The first lamp units 120 and 120a include a lamp frame 121, a plurality of first infrared lamps 123 arranged perpendicularly to the lamp frame 121, And a fan 125. The lamp frame 121 is vertically disposed on the side of the frame 180. The lamp frame 121 is provided with a power supply line (not shown) for supplying power to the plurality of first infrared lamps 123 although not shown in the figure.

The first infrared ray lamp 123 is supplied with power by the control signal of the controller 170 and irradiates the infrared ray to the substrate tray 10. The heat generated by the infrared rays irradiated from the first infrared lamp 123 is irradiated in the range of 200 ° C to 260 ° C.

Generally, the melting point of the substrate tray 10 made of a plastic resin is in a range of 210 ° C to 220 ° C. Accordingly, the high temperature heat generated in the first infrared ray lamp 123 is irradiated to the substrate tray 10. The burrs having a small size on the surface of the substrate tray 10 disappear when heated at a high temperature, and burrs with a large size are thermally fused to the surface of the substrate tray 10 while melting. The heat-welded burr is melted and adhered to it so that it maintains a sharp and smooth shape.

At this time, when the high temperature heat is contacted for a long time, the substrate tray 10 itself is thermally deformed, so that the first workpiece moves along the feeder 110 in a short time and the first infrared lamp 123 Indirectly.

The blowing fan 125 is accommodated in the rear of the first infrared lamp 123 inside the lamp frame 121. The blowing fan 125 rotates and forms an air flow to supply the high-temperature heat radiated from the first infrared lamp 123 toward the first conveying chains 113 and 113 '.

The transfer switching unit 130 switches the transfer direction of the substrate tray 10 transferred along the transfer unit 110 to supply the second workpiece to the transfer unit 150. The transfer switching unit 130 transfers the substrate tray 10 positioned on the waiting roller 117 to the second entry roller 151 of the second workpiece transfer unit 150 as shown in FIG. ).

Whereby the second workpiece is transferred to the transfer section 150 such that the substrate tray 10 to which the long shaft 13 has been transferred forward is directed to the front side of the short axis 15.

The conveyance switching unit 130 includes a pressure plate 131 for pressing the substrate tray 10 and a pressure shaft 135 for supporting the pressure plate 131 and having a length extended and contracted, And a driving unit 133. The pressure plate driving part 133 is driven by a control signal of the control part 170 to extend the pressing axis 135. [ The presser plate 131 pushes the substrate tray 10 to move the second workpiece to the second entry roller 151 of the feeder 150 when the pressing shaft 135 is extended.

The cooling unit 140 is located above the waiting roller 117 and cools the substrate tray 10 placed on the waiting roller 117. [ The cooling unit 140 is located at an upper portion of the position corresponding to the waiting roller 117 as shown in Fig. For this, the cooling unit 140 may be installed on the ceiling or may be installed at a predetermined height from the waiting roller 117 by a separate supporting member (not shown).

The cooling unit 140 supplies the cool air to the substrate tray 10 to remove residual heat remaining on the short axis 15 of the substrate tray 10 by the heat radiated from the first lamp units 120 and 120a. When the second workpiece is immediately fed to the feeder 150 without cooling of the cooling part 140, heat is applied to the long shaft 13 again in a state where residual heat remains on the short shaft 15, 10) themselves may be thermally deformed.

The cooling unit 140 is provided in the form of an air conditioner to supply a cold air stream. The temperature of the cool air supplied from the cooling unit 140 may be determined in consideration of the thickness and size of the substrate tray 10 to be transported, the temperature of the first infrared lamp 123, the transport speed, and the like.

At the waiting roller 117, the substrate tray 10 is cooled while staying in the range of 8 seconds to 15 seconds.

The second processed product transfer unit 150 transfers the first processed product in a direction orthogonal to the transfer unit 110 so that the burr of the long axis 13 of the substrate tray 10 can be removed. The second processed product transfer unit 150 includes a second entry roller 151 that receives the substrate tray 10 from the waiting roller 117 and a second entry roller 151 that shortens the substrate tray 10 supplied from the second entry roller 151 A second conveying chain interval adjusting unit 155 for adjusting the interval between the pair of second conveying chains 153 and 153 ', a second conveying chain interval adjusting unit 155 for adjusting the interval between the pair of second conveying chains 153 and 153' And a discharge roller 159 which is conveyed along the second conveyance chains 153 and 153 'to discharge the substrate tray 10 from which the burrs of the long axis 13 are discharged, .

A plurality of second processed parts 160 and 160a are alternately provided on both sides of the transmitting part 150 to apply infrared rays to the long axis 13 of the substrate tray 10 to form burrs on the surface of the long axis 13 Remove.

The configuration of the second processed product transfer unit 150 and the second lamp units 160 and 160a is the same as that of the first processed product described above and the first lamp unit 120 and 120a.

The control unit 170 controls the respective components so that the respective components can be operated according to the driving conditions inputted by the operator. Here, the operator inputs driving conditions in accordance with the standard of the substrate tray 10 for removing burrs. The driving conditions include a conveying speed of the first conveying chains 113 and 113 'and the second conveying chains 153 and 153', a temperature condition depending on the outputs of the first and second ramps 120 and 120a and 160 and 160a, The cooling air temperature of the unit 140, the time when the substrate tray 10 stays and cools at the waiting roller 117, and the like.

The operation of the apparatus for removing resin burr 100 according to the present invention having such a configuration will be described with reference to Figs. 1 to 6. Fig.

The operator sets the driving conditions so as to meet the specification of the resin-finished product, for example, the substrate tray 10, from which the burr is to be removed. The interval d1 between the first conveyance chains 113 and 113 'and the interval d2 between the first conveyance chains 113 and 113' are set to match the width (W1 in Fig. 3) of the long axis 13 of the substrate tray 10 and the width And the distance d2 between the second transport chains 153 and 153 '. At this time, the distance d1 of the first conveying chains 113 and 113 'is adjusted through the first conveying chain interval adjusting portion 115 and the interval d2 of the second conveying chains 153 and 153' Through the gap adjusting unit 155.

When the operator supplies power, the respective components are driven in accordance with the input driving conditions. For example, in order to remove burrs of the substrate tray 10 having a thickness of 1.2 mm, a length of the long shaft 13 of 392 mm and a length of the short shaft 15 of 243 mm, the first conveying chains 113 and 113 ' (153,153 ') are moved at a speed of 12 meters per minute. The first infrared lamp 123 is output at 210 to 230 ° C, and the second infrared lamp 163 is output at 220 to 250 ° C.

The operator laminates a plurality of substrate trays 10 to each other and supplies the first workpiece to the first entry roller 111 of the transfer section 110. [ As shown in FIG. 3, the plurality of substrate trays 10 are fed to the first conveying chains 113 and 113 'by the inclined surfaces of the first entry rollers 111. At this time, the first guide plate 112 is provided at the interface between the first entry roller 111 and the first conveyance chains 113 and 113 ', and the first conveyance chains 113 and 113' .

When the first conveying chains 113 and 113 'are rotated at a predetermined moving speed, the substrate tray 10 is moved along the first conveying chains 113 and 113'. At this time, the long axis of the substrate tray 10 faces forward and the short axis 15 faces the first infrared lamps 123 on both sides. Infrared rays and hot air are supplied from the first lamp units 120 and 120a alternately arranged on the left and right of the first transfer chains 113 and 113 '. The first infrared lamp 123 is driven, and the blowing fan 125 rotates to supply hot air.

The burr formed in the short shaft 15 is melted at a temperature (H) of 210 to 230 ° C irradiated by the first infrared lamp 123 due to the characteristics of the plastic resin melting at a temperature of 210 to 220 ° C. The burrs of small size are burned and removed, and the burrs of large size are thermally fused to the rim surface of the substrate tray 10 while melting.

The substrate tray 10 enters the waiting roller 117 as shown in Fig. The substrate tray 10 comes into contact with the frame 180 in the corner area where the first workpiece transfer part 110 meets the second workpiece transfer part 150 and stops its position.

In this state, the substrate tray 10 is stopped for a predetermined period of time, for example, 10 seconds, and is brought into contact with the cold air C supplied from the cooling unit 140. The residual heat remaining on the short shaft 15 is removed while being in contact with the cold wind C.

When the waiting time has elapsed, the control unit 170 drives the pressure plate driving unit 133 to cause the pressure plate 131 to press the substrate tray 10 to the second workpiece conveyance unit 150 as shown in FIG. 5 . The substrate tray 10 is pressed by the pressure plate 131 so that the feeding direction of the substrate tray 10 is switched so that the minor axis 15 faces forward and the major axis 13 faces both sides.

The substrate tray 10 is moved along the second transport chains 153 and 153 ', and receives infrared rays and hot air from the second lamp units 160 and 160a, which are alternately arranged on both sides. The burr formed on the long axis of the substrate tray 10 is removed or thermally fused to the heat.

The substrate tray 10 from which the burrs of the short shaft 15 and the long shaft 13 have been removed is discharged to the discharge roller 159 and the operator collects the substrate tray 10.

As described above, the resin-finished product burr removing apparatus according to the present invention automatically transfers the workpieces formed with the burrs in different directions along the conveying portion, and indirectly comes into contact with the infrared lamp.

Whereby heat of high temperature generated in the infrared lamp is burned or thermally fused on the surface of the resin product to be removed. When the burr is removed, the surface of the resin-finished product is smoothly formed, so that the surface finish of the product can be improved. In the case of transferring the product like the substrate tray, scratches on the product surface can be prevented, can do.

Further, the resin-finished product deburring device according to the present invention can be used interchangeably with resin-finished products of various sizes because the interval between the transfer chains for transferring the resin-finished products is adjusted.
