Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sheet sealing apparatus,

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 more particularly, to a sheet fusing apparatus for a subgap covering capable of reducing manufacturing costs 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 circumferential surface and both end surfaces of the bush, and both ends of the protective sheet bonded to the outer circumferential surface are thermally bonded And then a protective sheet, which is bonded to both end surfaces of the negative electrode, was bonded to the protective sheet covering the outer peripheral surface of the negative electrode.

However, as the thermal bonding 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.

[

The fusing means 800 is for thermally adhering both end portions S1 and S2 of the sheet S to be overlapped on the upper side of the work table 200 and includes a heating tool 810 and a pressing tool 820, .

7, the heating tool 810 is mounted on one side of the upper and lower movable members 700 so as to move up and down together with the upper and lower movable members 700. The lower end of the heating tool 810, The material 700 is positioned between the overlapped ends S1 and S2 of the sheet S when it is lowered so that heat is applied to the first adhering portion S1 located at the overlapped lower portion of the sheet S, 320 move along the overlapping ends S1, S2 of the sheet S to be coated.

In this case, 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 ° C) by a heating means such as a heater, It is preferable that a temperature sensor (not shown) and a temperature display unit 811 are provided for checking whether or not heat is applied to the adhesive portion S1 at a set temperature.

The pressing tool 820 is installed on one side surface of the up / down moving member 700 so as to move up and down together with the up / down moving member 700 like the heating tool 810, The heating tool 810 applies heat to the upper surface of the first bonding portion S1 and moves the second bonding portion S2 positioned to be overlapped with the heating portion on the upper surface of the first bonding portion S1, And is pressed by the first bonding portion S1 subjected to heat so that the overlapping both end portions S1 and S2 of the covering sheet S are thermally bonded to each other.

8, the pressing tool 820 is installed up and down through the supporting bracket 821 coupled to the upper and lower movable member 700 and the lower part of the supporting bracket 821 through the third elevating means 850 A guide rod 823 penetrating through the support bracket 821 so as to guide the lifting and lowering of the fixing bracket 822 to be coupled to the fixing bracket 822 and the second adhesive portion S2, And a pressing roller 824 rotatably coupled to the fixing bracket 822 with respect to the center axis so as to press and move on the bonding portion S1.

At this time, the pressing tool 820 is interposed between the supporting bracket 821 and the fixing bracket 822 so as to penetrate the guide rod 823 in order to relieve the impact transmitted through the pressure roller 824 as shown in FIG. 9 An elastic member 826 fitted to the outer surface of the guide rod 823 located under the auxiliary bracket 825 to elastically support the fixing bracket 822 and an elastic member 826 for adjusting the elastic force of the elastic member 826 And a tension adjusting member 827 coupled to the guide rod 823 located at the upper portion of the auxiliary bracket 825 to be fixed to the upper surface of the auxiliary bracket 825.

10, one or more height adjusting holes 720 and 830 for adjusting the mounting height of the support bracket 821 may be formed on at least one of the upper and lower movable members 700 and the support bracket 821, 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 821 and the upper and lower movable members 821, 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, the support 100 is provided with a limit switch L whose operation is controlled by control means so that the vertical guide bar 600 is moved at a predetermined position, and the limit guide bar 300 is provided with a limit switch It is preferable that a safety block B is provided which forcibly restrains the movement of the vertical guide bar 600 by contacting the side surface of the vertical guide bar 600 when moving out of a predetermined position due to a malfunction of the vertical guide bar 600 .

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 sheet fusing device for subgross coating having the above-described 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 in a state in which the first bonding portion S1 and the second bonding portion S2 are disposed on the upper surface of the work table 200 The first cylinder 401 and the second cylinder 452 are driven at the same time and then the other one is sequentially driven so that the first bonding portion S1 and the second bonding portion S2 are driven It is preferable that the overlapped arrangement state is easily fixed.

In this state, as shown in FIG. 14 (a), when the second moving means 750 is driven to lower the upper moving member 700, the lower end of the heating tool 810, as shown in FIG. 15, And the pressing tool 820 lowered together with the heating tool 810 is further lowered through the third elevating means 850 to be positioned at a position corresponding to the height of the pressing roller 824 are positioned at such a height as to press the second adhering portion S2 and adhere to the first adhering portion S1 placed on the work table 200. [

At this time, when the auxiliary bracket 825, the elastic member 826 and the tension adjusting member 827 are provided in the pressing tool 820, the pressure roller 824 lowered by the third elevating means 850 is pressed against the second adhesive The initial impact that the lower surface of the pressing tool S2 is brought into close contact with the upper surface of the first adhering portion S1 is relieved so that not only the pressing tool 820 but also other devices to which the pressing tool 820 is coupled are also protected from impact There is an advantage.

The vertical guide bar 600 and the fusing unit 800 are moved along the overlapped portion of the first adhesive portion S1 and the second adhesive portion S2 by driving the driving unit 322 constituting the moving means 320, As shown in FIGS. 16A and 16B, the heat bonding process of the first bonding portion S1 and the second bonding portion S2 by the fusing means 800 at this time is as shown in FIG. 14 (b) The lower end of the heating tool 810 is moved in a region between the first adhering portion S1 and the second adhering portion S2 placed on the workbench 200 so as to overlap with each other so as to apply heat to the upper surface of the first adhering portion S1, The roller 824 moves in a pressed state such that the upper surface of the second adhering portion S2 is in close contact with the first adhering portion S1 placed on the work table 200. [

As the second adhering portion S2 is pressed against the first adhering portion S1 heated by the pressing tool 820 immediately after the heat is applied by the heating tool 810, the first adhering portion S1) and the second adhering portion (S2) are thermally adhered to each other, so that a cylindrical sheet (S) for covering can be manufactured.

The reason why the width of the pressing force by the pressing roller 824 is larger than the width of heat applied by the heating tool 810 is that when the heating tool 810 moves, The first adhesive portion S1 and the second adhesive portion S2 are pressed against each other as well as the portion where the first adhesive portion S1 and the second adhesive portion S2 overlap with each other when heat is applied to the first adhesive portion S1, So that the portion to be thermally adhered can be accurately and uniformly adhered without departing from the set region.

As the driving unit 322 is driven, the driving force of the driving shaft 321 is transmitted to the driving shaft 321 of the horizontal guide bar 300 by moving the heating tool 810 and the pressing tool 820 along the longitudinal direction of the horizontal guide bar 300, Is rotated in either the clockwise or counterclockwise direction. As the rotary shaft 321 is rotated, the flow member 323 moves forward or backward along the spiral direction of the outer surface of the rotary shaft 321 A vertical guide bar 600 is installed in the flow member 323 through a connecting member 500 and a fusing unit 800 is installed in the vertical guide bar 600 through a vertical moving member 700 Therefore, the heating tool 810 and the pressing tool 820 are moved by the movement of the flow member 323.

After the thermal bonding of the both end portions S1 and S2 of the sheet S is completed by the above method, the pressing tool 820 is driven by the driving of the third elevating means 850 and the second elevating means 750, And the upper and lower movable members 700 are raised to an initial height set as shown in Figure 14C so that the driving unit 322 is driven to rotate in the reverse direction to rotate the first and second adhesive portions S1, The vertical guide bar 600 that has been moved from one side of the horizontal guide bar 300 to the other side for thermal bonding of the vertical guide bar 600 is returned to its original position as shown in FIG. The fixing member 400 is moved up and down by the driving of the first elevating means 450.

When the fixing member 400 is lifted and fixed to the upper surface of the work table 200 to fix the upper surface of the work table 200 to the upper surface of the work table 200, Since only one longitudinal end portion of the work table 200 is fixed to the support body 100, the work table 200 can be moved along the longitudinal direction of the work table 200, The sheet S can be pulled out.
