Description

TECHNICAL FIELD [0001] The present invention relates to a heat sealing device for a sheet,

The present invention relates to a method of inserting a covering sheet made of a resin material so as to surround an outer circumferential surface of a bag in order to surround and protect an outer circumferential surface of a bag having a function of fixing the fishing gear and a function of displaying a position, And which can quickly and easily heat-seal the sheet, thereby reducing the manufacturing cost by increasing work safety and productivity.

Generally, a buoy is installed on the sea surface by buoyancy, and has been used for a fixing function of installing a fishing net such as various kinds of nets in seawater and a display function for easily identifying a place where fishing gears are installed.

Most of these bulges are made of expanded polystyrene or plastic. Among them, expanded polystyrene bulb is advantageous in that it is inexpensive and light and easy to carry. On the other hand, it has a problem of corrosion due to seawater or sunlight, In addition to this, frequent replacement is required as the buoyancy is weakened by absorbing seawater. In addition to this, due to the weak durability, debris generated when rubbing with a rope that ties a fish or a buoy covers the sea surface, And the use thereof is regulated.

In addition, in the case of the plastic part, the outer shape of the part can be formed into various shapes and the life time is longer than that of the expanded polystyrene part. However, when the price is high and the weight is heavy and buoyancy is weak, There is a problem that it is easily broken even in a small impact, and the function as a bulge is lost.

In order to improve the disadvantages of the foam made of expanded polystyrene or plastic, an air injection type bulb which is strong against impact, light in weight, and excellent in buoyancy is proposed as in Korean Registered Utility Model No. 0228960.

However, in the case of tearing or damaging the outer surface, water infiltrates into the inside of the air inflow port, and the function of the inflow port is lost, and as the compressed air inside the port is gradually expanded and contracted according to the climatic change, And thus the air needs to be newly injected or replaced in the portion where the buoyancy is weakened.

Korean Patent No. 10-0615435 discloses that a cover made of expanded polystyrene made of a cylindrical material is covered and protected by using a cover made of PE or synthetic resin. However, since the cost of manufacturing such a cover is high, And when the gap is formed in the coupling surface of the semi-cylindrical shape, the seawater flows into the gap and the buoyancy is weakened.

In order to protect the outer surface of the cylindrical bushing with a protective body, a protective sheet made of a synthetic resin material is cut to a size that can cover the outer peripheral surface and both end surfaces of the bush, and both ends of the protective sheet bonded to the outer peripheral surface are thermally fused And then a protective sheet, which is bonded to both end surfaces of the negative electrode, was thermally fused to the protective sheet covering the outer peripheral surface of the negative electrode.

However, since the heat sealing of the protective sheet cut to wrap the outer circumferential surface of the bulb is manually performed, the labor cost is increased while the productivity is lowered and the product price is increased, and the operator directly operates the high- There has been a problem that causes safety accidents.

At this time, the reason why only one side of the work table 200 is coupled to the supporting body 100 is to easily take out the sheet S to be coated in a thermally adhered state, which will be described later in more detail.

4, the horizontal guide bar 300 is coupled to the support 100 so as to be horizontally spaced apart from the upper side of the work table 200, and the horizontal guide bar 300 is reciprocated A moving means 320 is provided.

The fitting groove 311 or the fitting protrusion 324 may be formed to correspond to the outer surface of the flow member 323 and the fitting groove 311 according to the first embodiment may be formed along the longitudinal direction of the guide groove 310 And the fitting protrusions 324 are formed on both outer surfaces of the flow member 323 at positions corresponding to the fitting grooves 311. [

1 and 2, the fixing member 400 is mounted on the horizontal guide bar 300 and is lifted and raised by the first elevating means 450. This is because the first and second adhesive portions S1 and S2 The side of the covering sheet S is pressed against the upper surface side of the work table 200 so as not to interfere with the first bonding portion S1 and the second bonding portion S2 when they are placed on the upper surface of the work table 200, So as to prevent the flow.

The fixing member 400 is for fixing both sides of the covering sheet S to the workbench 200 by pressing the first fixing frame 410 to press one side of the covering sheet S, And the second fixing frame 420 presses the other side of the sheet S so that the first elevating and lowering means 450 is also structured by the first fixing frame 410 and the second fixing frame 420, It is preferable that the first cylinder 451 and the second cylinder 452 are configured so that the first cylinder 451 and the second cylinder 420 can be lifted and lowered individually.

The first fixing frame 410 and the second fixing frame 420 may have a bar shape elongated along the longitudinal direction of the work table 200. However, It may be formed as a square plate or a rectangular frame having a size that does not deviate from the upper surface of the work table 200.

6, the vertical guide bar 600 is installed perpendicularly to the horizontal guide bar 300 through the connecting member 500. The connecting member 500 is coupled to the flow member 323, 321 at the same time.

The vertical guide bar 600 is spaced a predetermined distance from the upper side of the work table 200 so that both end portions S1 and S2 of the sheet S can be easily placed on the upper side of the work table 200, When the fusing means 800 is lowered to the work table 200 side, the first and second adhesive portions S1 and S2 should be installed at a height enough to thermally adhere to each other.

The vertical guide bar 600 according to the first embodiment is provided with a vertical moving member 700 and a fusing unit 800 to be described later on both sides of the vertical guide bar 600. However, The upper and lower movable members 700 and the fusing unit 800 are installed on the outer surfaces of the vertical guide bars 600. The upper and lower movable members 700 and 700 They may be installed symmetrically.

The upper and lower movable members 700 are provided symmetrically with respect to the vertical guide bar 600 so that when the flow member 323 coupled to the rotary shaft 321 reciprocates along the guide groove 310, The limit switches L to be described later are respectively raised and lowered by the second lifting means 750 at a position where the heating tool 810 is sensed.

In order to guide the vertical guide bar 600 to be horizontally moved along the horizontal guide bar 300, any one of the surfaces, on which the horizontal guide bar 300 and the vertical guide bar 600 are coupled to each other, A horizontally moving guide protrusion 610 having a protruding shape may be formed and a horizontally moving guide groove 330 having a concave shape may be formed on the other of the protrusions 610 so that the horizontally moving guide protrusion 610 may be inserted .
In order to allow the vertical moving member 700 to be vertically moved along the vertical guide bar 600, the vertical guide bar 600 and the vertical moving member 700 are coupled to each other, A vertical movement guide groove 620 having a concave shape may be formed so that the vertical movement guide protrusion 710 having a protruding shape is formed and the other one of the vertical movement guide protrusions 610 is fitted to the other one .
In order to guide the horizontal movement of the connecting member 500 provided on the vertical guide bar 600 along the horizontal guide bar 300 in a state where the connecting member 500 is installed on the flow member 323, A horizontal movement guide protrusion 510 having a protruding shape is formed on one of the surfaces of the connecting member 500 in the state where the connecting member 500 is installed on the member 323, The horizontal movement guide groove 330 may be formed to have a concave shape so that the horizontal movement guide groove 330 can be moved in a state in which it is inserted.

The horizontal guide bar 300 according to the first embodiment has horizontally moving guide grooves 330 along the longitudinal direction (transverse direction) on the surface facing the vertical guide bar 600 and the connecting member 500 The connecting member 500 and the vertical guide bar 600 are formed with horizontally moving guide protrusions 510 and 610 that are inserted in the horizontal movement guide groove 330 and are respectively connected to the vertical guide bar 600 At least one vertical movement guide groove 620 is formed along the longitudinal direction (vertical direction) on the surface facing the upper and lower movable members 700, and the upper and lower movable members 700 have vertical movement guide grooves 620 The vertical movement guide protrusion 710 is formed to be inserted into the vertical movement guide protrusion 710. [

7, the fusing means 800 is provided symmetrically with respect to the vertical guide bar 600 via the upper and lower movable members 700, and each of the fusing means 800 is mounted symmetrically by means of the second elevating means 750, A heating tool 810 and a pressing tool 820 which lift and lower the first adhesive portion S1 and the second adhesive portion S2 in a direction opposite to the first adhesive portion 700 with the first adhesive portion 700 and the second adhesive portion S2.

The second elevating means includes a first heating tool 811 and a first pressing tool 821 for individually driving the fusing means 800 installed on the left and right sides of the work table 200, And a second fusing tool 812 provided on the left side of the work table 200 and composed of a second heating tool 812 and a second pressing tool 822. The first fusing device 801 is mounted on the right side of the work table 200, And a left cylinder 752 for raising and lowering the means 802.

Here, the heating tool 810 is positioned between the first bonding portion S1 and the second bonding portion S2, the lower end of which overlies the upper side of the work table 200, and the first bonding portion S1 And the pressing tool 820 is installed on the rear side where the heating tool 810 moves and the second adhesive portion S2 placed on the overlapped upper portion is heated by the heating tool 810 Is applied to the first bonding portion S1.

In other words, the lower end of the heating tool 810 is positioned between the overlapped ends S1 and S2 of the sheet S when the upper and lower movable members 700 are lowered, and the pressing tool 820 is positioned between the overlapped ends S1 and S2 of the sheet S, The sheet S is positioned at such a height as to be able to press the second sheet S2 so as to be in close contact with the first sheet S1 so that the sheet S moves along the overlapped ends S1 and S2 of the sheet S as the moving means 320 is driven So that the first adhesive portion S1 and the second adhesive portion S2 are thermally adhered.

However, since the fusing unit 800 according to the first embodiment of the present invention is subjected to heat bonding by applying pressure to the pressing tool 820 after applying the first bonding portion S1 heat using the heating tool 810, When the vertical guide bar 600 and the fusing unit 800 are moved from the right side to the left side of the work table 200 by the fusing unit 320, the first fusing unit 801 moves the first fusing unit S1 and the second fusing unit S2 And the second fusing means 802 should be moved to the vertical guide bar 600 in an elevated state.

In contrast, when the vertical guide bar 600 and the fusing unit 800 move from the left to the right of the work table 200, the first fusing unit 801 should be moved to the vertical guide bar 600 in an elevated state , The second fusing unit 802 should be moved in a lowered state so that the first bonding unit S1 and the second bonding unit S2 can be thermally adhered to each other.

The heat applied to the first bonding portion S1 through the heating tool 810 may be a gas heated to a predetermined temperature (550 to 650 deg. C) by a heating means such as a heater, It is preferable that a temperature sensor (not shown) and a temperature display unit 830 are provided for checking whether or not heat is applied to the adhesive portion S1 at a set temperature.

8, the pressing tool 820 is installed up and down through the supporting bracket 841 coupled to the upper and lower movable members 700 and the lower part of the supporting bracket 841 through the third elevating means 850 A guide rod 843 penetrating through the support bracket 841 and guided by the fixing bracket 842 so as to be guided by the fixing bracket 842 and the fixing bracket 842 and the second adhesive portion S2, And a pressing roller 844 rotatably coupled to the fixing bracket 842 with respect to the center axis so as to press and move on the bonding portion S1.

9, the pressing tool 820 is inserted into the supporting bracket 841 and the fixing bracket 842 such that the guide rod 843 penetrates through the supporting bracket 841 and the fixing bracket 842 to relieve the shock transmitted through the pressure roller 824. [ An elastic member 846 which is fitted to the outer surface of the guide rod 843 located under the auxiliary bracket 845 and elastically supports the fixing bracket 842; And a tension adjusting member 847 coupled to the guide rod 843 located on the upper portion of the auxiliary bracket 845 to be fixed to the upper surface of the auxiliary bracket 845.

As shown in FIG. 10, at least one height adjusting hole 720 and 848 for adjusting the height of the support bracket 841 may be formed on at least one of the upper and lower support 700 and the support bracket 841. This is because when the first elevating means 450, the second elevating means 750 and the third elevating means 850 are formed by cylinders, the height at which the heating tool 810 and the pressing tool 820 descend is finely And the lower end of the heating tool 810 is inserted through the height adjusting hole 720 formed on the surface where the heating tool 810 and the upper and lower movable members 700 are engaged, The pressing roller 824 is positioned between the opposite end portions S1 and S2 so that the pressing roller 824 is positioned between the supporting sheets 841 and the upper and lower movable members 841, The pressing force applied to the pressing tool 820 can be minimized while pressing both end portions S1 and S2 of the pressing tool 820 There is an advantage to be able to adjust to the position.

11, a vertical guide bar 600 and a vertical moving member 700 coupled to the vertical guide bar 600 and a fusing unit 800 are moved to a predetermined position on the support 100, A limit switch L is provided for controlling the operation of the limit switch L. When the limit switch L is moved out of a predetermined position due to a malfunction of the limit switch L, It is preferable that a safety block B for forcibly restricting the movement of the guide bar 600 is provided.

On the other hand, as shown in FIG. 3, on the top surface of the work table 200, a second adhesive portion S2 positioned on the upper portion of the work table 200 is spaced apart from the first adhesive portion S1 The separating member 210 is moved downward to a position corresponding to the upper surface of the work table 200 when the pressing member is pressed by the pressure roller 824, It is preferable that a plurality of the electrodes are formed along the longitudinal direction.

This is because when both end portions S1 and S2 of the sheet S are overlapped on the upper surface of the work table 200, the overlapped ends S1 and S2 are in close contact with each other, In order to apply heat to the first bonding portion S1 located at the lower portion where the lower end portion of the heating tool 810 is overlapped when the lower portion of the heating tool 810 is lowered, it is necessary to artificially raise the second bonding portion S2 located at the upper portion where the operator overlaps It is to solve the inconvenience.

The separating member 210 includes a tubular body 211 detachably coupled to a lower surface of the work table 200 and a separator 210 disposed on the upper surface of the body 211 to prevent the separating member 210 from being separated from the body 211, The protrusion 212 and the spring 213 accommodated in the body 211 and adapted to elastically support the support protrusion 212. In this case, when the support protrusion 212 is drawn out, The upper end of the support protrusion 212 should be positioned at the same height as the upper surface of the work table 200 or at a lower height in a state in which the support protrusion 212 is pressed by the pressure roller 824.

The reason why the spacing member 210 is pressed by the pressure roller 824 is that the first bonding portion S1 is set to overlap each other to bond both end portions S1 and S2 of the covering sheet S, And the position of the second adhesive portion S2 are not changed.

The reason why the second adhesive portion S2 is moved downward when pressed by the pressure roller 824 is that when the second adhesive portion S2 is pressed by the pressure roller 824 and thermally adhered to the first adhesive portion S1, The reason why the sheet S is restored to its original state due to the release of the pressure by the pressure roller 824 is that the plurality of sheets S to be coated are repeatedly The process of artificially manipulating the separating member 210 so as to protrude in the original state during the process of thermally adhering to the separating member 210 is omitted, thereby enhancing the convenience of the operation and increasing the production efficiency.

When the separating member 210 is formed on the upper surface of the work table 200, even if both end portions S1 and S2 of the sheet S are overlapped, the separating member 210 is spaced apart from the separating member 210 So that the lower end portion of the heating tool 810 lowered by the upper and lower movable members 700 can be positioned between the overlapped end portions S1 and S2 of the covering sheet S without the assistance of the operator There is an advantage.

Hereinafter, the operation of the heat sealer of the sub-coated sheet having the above structure will be described.

First, as shown in FIGS. 12 and 13, the first bonding portion S1, which is cut to a size that can cover the outer surface of the mouth when the thermal bonding is performed, is positioned on the upper surface of the work table 200, And the first cylinder 451 is driven so that the first adhering portion S1 is moved by the first securing frame 410 to the work table 200 To be fixed to the upper surface of the frame.

Thereafter, the outer surface of the work table 200 is placed so as to form a wrapped sheet S so that the second adhesive portion S2 overlaps the first adhesive portion S1, and the second adhesive portion S2 The second bonding portion S2 is moved by the second fixing frame 420 to the work table 200 by driving the second cylinder 452 after the other side of the covering resin is brought into close contact with the upper surface of the spacing member 210, As shown in FIG.

The first cylinder 451 and the second cylinder 452 may be driven after the first bonding portion S1 and the second bonding portion S2 are disposed on the upper surface of the work table 200, At this time, rather than driving the first cylinder 451 and the second cylinder 452 at the same time, one of the first cylinder 401 and the second cylinder 452 is driven first, and then the other one is sequentially driven so that the first bonding portion S1 and the second bonding portion S2 overlap each other It is preferable to easily fix the state of being disposed.

In this state, when the right cylinder 751 is driven to bring the first fusing device 801 into a lowered state as shown in FIG. 14A, the lower end of the first heating tool 811, as shown in FIG. 15, The first pressing tool 821 lowered together with the first heating tool 811 is located at a position corresponding to the height between the adhering portion S1 and the second adhering portion S2, The second fusing unit 802 is positioned at a height enough to press the second fusing unit S2 against the first fusing unit S1 placed on the workbench 200, Lt; / RTI >

At this time, when the auxiliary bracket 845, the elastic member 846 and the tension adjusting member 847 are provided to the first pressing tool 821, the pressing roller 844a lowered by the third elevating means 850 It is possible to relieve the initial impact that the lower surface of the second adhering portion S2 is brought into close contact with the upper surface of the first adhering portion S1 so that the first pressure applying tool 821 as well as other devices to which the first pressing tool 821 is coupled So that it is protected against impact.

14 (b), when the moving means 320 is driven to move the vertical guide bar 600 and the first fusing means 801 from the right side to the left side of the workbench, the first bonding portion S1 and the second bonding portion The thermal bonding process of the first bonding portion S1 and the second bonding portion S2 by the first fusing means 801 at this time will be described with reference to FIG. The lower end of the first heating tool 811 moves in a region between the first bonding portion S1 and the second bonding portion S2 placed on the work table 200 so as to overlap with each other and is disposed on the upper surface of the first bonding portion S1 The first pressing roller 844a constituting the first pressing tool 821 is pressed in such a manner that the upper surface of the second bonding portion S2 is brought into close contact with the first bonding portion S1 placed on the work table 200 .

The first pressing tool 811 and the first pressing tool 821 are moved to the left side of the work table 200 by the moving means 320. When the driving unit 322 is driven, Is rotated in the clockwise or counterclockwise direction and the rotating member 323 is moved to the left along the spiral direction of the outer surface of the rotating shaft 321 by the rotation of the rotating shaft 321 And a vertical guide bar 600 is connected to the flow member 323 via a connecting member 500. The vertical guide bar 600 is provided with a fusing unit 800 via a vertical moving member 700, The first heating tool 811 and the first pressing tool 821 can be moved by the movement of the flow member 323.

As the second adhesive portion S2 is pressed against the first adhesive portion S1 heated by the first pressing tool 821 immediately after the heat is applied by the first heating tool 811, The first adhering portion S1 and the second adhering portion S2 are thermally adhered to each other to complete the manufacture of a covering sheet S in a cylindrical shape so as to cover the outer surface of the adhering portion.

When the limit switch L senses the second heating tool 812 after the thermal bonding by the first fusing unit 801 is completed, the moving unit 320 stops operating, The fixing member 200 which has pressed both sides of the work table 200 is raised to its original height so that the cylindrical receiving sheet S coupled in the shape of wrapping the outer surface of the work table 200 can be taken out of the work table 200, The first fusing unit 801 and the second fusing unit 802 are provided at the other end of the work table 200 because only one longitudinal end portion of the work 200 is fixed to the support body 100, Can be pulled out through the right end portion provided with the heat-sealable sheet (S).

14 (c), the first fusing unit 801 is moved in the direction in which the first fusing unit 801 is pulled out of the vertical guide bar 600 The second fusing unit 802 in an upwardly raised state is lowered to a height when the first fusing unit S1 and the second fusing unit S2 are thermally adhered by the first fusing unit 801 It is possible to perform the thermal bonding preparation process through the second fusing unit 802 by means of a separate operation lever, The detection sensor may be installed at the right end of the detection sensor so that the detection sensor can be operated automatically when the detection of the completion of the taking-out of the sheet S is completed.

Thereafter, as shown in Fig. 14 (d), both end portions S1 and S2 of the new dressing sheet S are superimposed on the upper surface of the work table 200, When the moving means 320 is driven so that the vertical guide bar 600 and the second fusing means 802 move from the left to the right of the workbench as shown in Figure 14 (e) The lower end of the second heating tool 812 moves along the overlapped portion of the first adhering portion S1 and the second adhering portion S2 to apply heat to the upper surface of the first adhering portion S1, The pressing roller 844b constituting the pressing portion 822 presses the second adhering portion S2 so as to be in close contact with the first adhering portion S1 to effect thermal bonding.

Next, when the limit switch L detects the first heating tool 811 moved to the right side of the work table 200, the operation of the moving means 320 is stopped and the sheet S is fixed The holding member 200 is lifted and lowered and the sheet S to which the thermal bonding has been completed can be taken out from the workbench 200. [

At this time, even if the limit switch L fails to detect the first heating tool 811 and the second heating tool 812 due to a malfunction or the like, the movement of the vertical guide bar 600 is forced to the horizontal guide bar 300 It is possible to prevent breakage or safety accidents of the fusing means 800 and other devices provided with the fusing means in advance.

The reason why the width pressed by the pressure rollers 844a and 844b is larger than the width to be heated by the first heating tool 811 and the second heating tool 812 is that the first heating tool 811, The first pressing tool 821 and the second pressing tool 822 are moved in the same direction while the first pressing tool 821 and the second pressing tool 812 move while applying heat to the first bonding portion S1 without interfering with the spacing member 210 The first adhesive portion S1 and the second adhesive portion S2 are pressed to press the spacing member 210 together as well as the mutually overlapped portions when moving from the back along the first heating tool 811 and the second heating tool 812 So that the portion to be thermally adhered can be accurately and uniformly adhered without departing from the set region.

As described above, the covering sheet S cut to protect the outer circumferential surface of the cover is cut by a process in which the operator sets both end portions S1 and S2 of the covering sheet S on the work table 200 to overlap with each other, All the work processes are automatically performed through the control means except for the process of pulling the coated sheet S having been bonded from the work table 200 and the vertical guide bar 600 and the fusing means 800 are paired The two sheets of application sheets S can be thermally adhered to each other in the process of reciprocating the left and right sides of the work table 200 one by one so that the convenience of operation is increased and production efficiency is improved. So that the manufacturing cost can be greatly reduced and the operator does not need to operate the high temperature heating tool 810, and the work safety is also greatly improved.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
