Description

A heater for heat shrinking tube of vehicle's fluid transfer pipe

The present invention relates to a fluid transport pipe heat shrink tube heating device for a vehicle, and more particularly, by applying radiant heat even at the upper portion of the heat shrink tube, so that the heat shrink tube is in close contact evenly throughout the pipe through uniform heat transfer. It's about heating.

Among automobile parts, pipe and tube parts are used for the purpose of transporting fuel, fluid, and gas.

Pipe and tube parts are widely used for transporting fuel in conventional automobiles using fossil fuels.

In other words, the fuel pipe used for fuel transport is used for the purpose of transporting fuel from the storage tank to the engine.

On the other hand, the pipe and tube parts are used for the purpose of transporting oil in the brake system for braking.

The automobile fluid transport pipe is used as a flow path for fuel or brake fluid and is responsible for transporting related fluids and gases.

Among them, the brake pipe used in the automobile brake system is a metal pipe, and most of it is installed on the lower part of the vehicle, so there is a risk of damage due to exposure to various contaminants and external defects while driving.

In particular, corrosion problems caused by snow removal agents such as calcium chloride and potassium chloride, which are sprayed to prevent icy roads in winter, can cause safety accidents in vehicles.

Therefore, the brake pipe used in the automobile brake system can be protected by using a heat-shrinkable tube to prevent damage to its surface.

The heat-shrinkable tube is inserted outside the metal pipe for the purpose of protecting the conveying pipe and serves to protect the pipe.

Such a heat-shrinkable tube is a thermoplastic resin and uses the principle that the tube shrinks when heat of a certain temperature is applied using the thermal properties of a polymer material.

In other words, the heat-shrinkable tube assembled on the surface of the metal pipe may be attached to the surface of the metal pipe by heating the heat through a heating process.

However, in the conventional heating process as described above, in the case of a long pipe product, since a wide range of the heating device was controlled using a single temperature sensor, There was a problem in that the pipe adhesion quality of the heat-shrinkable tube was not uniform.

1 is a cross-sectional view of a heat-shrinkable tube heating device for a fluid transport pipe for a vehicle according to a preferred embodiment of the present invention and a control device thereof.

A plurality of fluid conveying pipes 101 wrapped with heat shrinkable tube 102 are placed on top of the conveying unit 110 and passed through the heating device.

The fluid transport pipe 101 is placed long in the direction to penetrate the ground, and accordingly, the radiant heat reflector 130 and the heating unit 120 also have a width equal to the length of the fluid transport pipe 101 in the direction of penetrating the ground. It will be understood as having a predetermined area extending to a long distance.

The apparatus for heating the fluid transport pipe heat shrink tube for a vehicle according to the first preferred embodiment of the present invention may include a transport unit 110 , a heating unit 120 , and a radiant heat reflector 130 .

In addition, the fluid transport pipe heat shrink tube heating device for a vehicle according to a preferred embodiment of the present invention is at least one of the transport speed control unit 201 , the heating temperature control unit 202 , the first position control unit 203 , and the second position control unit 204 . It may include any one or more.

A plurality of temperature sensing units 140 are provided inside the heating device 100 to measure the temperature of the heat-shrinkable tube 102 extrapolated to the fluid transport pipe 101 as well as measure the temperature inside the heating device 100 . .

The heating unit 120 and the radiant heat reflecting unit 130 may be provided inside the housing forming the outer shape of the heating device.

The housing has an inlet on the left so that the fluid transfer pipe 101 enters the housing, and an outlet on the right so that the fluid transfer pipe 101 goes out of the housing.

The transfer unit 110 may be formed of a conveyor belt that continuously moves from an inlet (in) to an outlet (out).

The fluid conveying pipe 101 in which the heat-shrinkable tube 102 is wrapped around the outer circumferential surface is placed on the upper end of the conveying unit 110 and conveyed to the right by the conveying unit 110 .

That is, the transfer unit 110 serves to transfer the fluid transfer pipe 101 to which the heat-shrinkable tube 102 is extrapolated.

In this case, the heating unit 120 is provided under the transfer unit 110 to heat the heat-shrinkable tube 102 .

The radiant heat reflector 130 is provided on the heat-shrinkable tube 102 transferred by the transfer unit 110 to reflect the radiant heat emitted from the heating unit 120 toward the heat-shrinkable tube 102 .

Therefore, since radiant heat is also transferred to the upper end of the heat-shrinkable tube 102, heat shrinkage of the heat-shrinkable tube 102 can be made more reliably.

In other words, the temperature of the lowermost outermost part of the fluid transport pipe 101, which is the closest point to the heating unit 120 at an instant in the heat shrink tube 102, and the fluid transport pipe ( By being able to reduce the temperature difference of the uppermost outermost part of 101 , heat shrinkage of the heat shrinkable tube 102 surrounding the fluid transport pipe 101 can be made more reliably.

On the other hand, the long groove portion 131 may be formed to be elongated in the longitudinal direction of the fluid transfer pipe 101 while having the same curvature as the radius of curvature of the fluid transfer pipe 101 in the radiant heat reflector 130 .

It may be preferable that a plurality of long groove portions 131 are provided in parallel with each other at equal intervals along the transfer direction of the transfer unit 110 .

In more detail, the long groove portion 131 has a shape that is recessed while having a predetermined curvature upward from the lower end of the radiation heat reflection unit 130 , and a plurality of pieces may be provided at equal intervals.

By being radiated at a right angle as much as possible to the outer circumferential surface of the heat-shrinkable tube 102 by the long groove portion 131, radiant heat transfer can be more concentrated.

On the other hand, in the heating device 100 according to the second preferred embodiment of the present invention, it is possible to raise and lower the radiant heat reflector 130 .

In other words, the first position control unit 203 is a radiant heat reflector when the measured temperature measured by the temperature sensing unit 140 is lower than the preset shrinkage temperature range of the heat-shrinkable tube 102 at the upper temperature of the heat-shrinkable tube 102 . (130) may be lowered by a predetermined distance, and when the measured temperature satisfies a preset shrinkage temperature range, the radiant heat reflector 130 may be returned to its original position.

This may be useful in winter or when the upper temperature inside the housing is lowered due to external influences.

That is, when the temperature of the upper space inside the housing is lower than the preset value due to the season or other reasons, the radiant heat reflector 130 is lowered by a predetermined distance to shorten the radiation distance.

As a result, the radiant heat transferred to the heat-shrinkable tube 102 can be further concentrated by shortening the radiation distance.

Thereafter, when the upper temperature inside the housing satisfies the preset shrinkage temperature range, the heat-shrinkable tube 102 can be prevented from being overheated by returning the radiant heat reflecting unit 130 to its original position.

In addition, the heating device 100 according to the third preferred embodiment of the present invention may further include a heat loss prevention film at the inlet (in) and the outlet (out).

In more detail, the first heat loss prevention film 151 is provided at the inlet, and the second heat loss prevention film 152 is provided at the outlet.

The upper end of the first heat loss prevention film 151 is rotatable in the housing of the heating device 100 , and the upper end of the second heat loss prevention film 152 is also rotatably provided in the housing of the heating device 100 .

Meanwhile, the heating device 100 according to the fourth preferred embodiment of the present invention may include a first caterpillar 161 and a second caterpillar 162 .

The first caterpillar 161 is in contact with the upper end of the fluid transport pipe 101 mounted on the transport unit 110 to rotate the fluid transport pipe 101 in the first direction with the longitudinal direction of the fluid transport pipe 101 as the center of rotation. rotate to

The second caterpillar 162 is in contact with the lower end of the fluid transport pipe 101 to rotate the fluid transport pipe 101 in a direction opposite to the first direction.

In other words, the first caterpillar 161 and the second caterpillar 162 may be in contact with the outer circumferential surface of the fluid conveying pipe 101 , and accordingly, the fluid conveying pipe 101 is rotatable in the clockwise direction.

At this time, when the first caterpillar 161 and the second caterpillar 162 are in contact with the outer circumferential surface of the fluid conveying pipe 101, the heat shrinkable tube 102 is wrapped around the longitudinal outer circumferential surface of the fluid conveying pipe 101 It may mean that it is in contact with the outer peripheral surface of the end side that is not there.

In other words, the outer circumferential surface of the fluid transport pipe 101 is in the form of a heat-shrinkable tube 102 wrapped around the whole along the longitudinal direction, but in some sections of both ends of the fluid transport pipe 101, the heat-shrinkable tube 102 is wrapped. The non-existent pure fluid conveying pipe 101 may be exposed, and the first crawler 161 and the second crawler 162 may be in contact with this partial section to rotate the fluid conveying pipe 101 .

The fluid conveying pipe 101 and the heat-shrinkable tube 102 may eventually rotate by themselves and translate (transfer) to the right as shown by an arrow.

Therefore, the heat-shrinkable tube 102 is able to achieve more smoothly heat-shrinkage by uniform heat transfer to the outer circumferential surface as a whole.

In addition, the rotational speed of the first caterpillar 161 and the rotational speed of the second caterpillar 162 can be individually controlled.

That is, when the rotation speed of the first caterpillar 161 and the rotation speed of the second caterpillar 162 are the same, the conveying speed of the fluid conveying pipe 101 becomes the same as the speed of the conveying unit 110 .

However, if the rotational speed of the first caterpillar 161 is controlled to be greater than the rotational speed of the second caterpillar 162 , the relative speed of the fluid transfer pipe 101 in the right direction with respect to the transfer unit 110 is further increased. As a result, the fluid transport pipe 101 is rotated clockwise, and a translational motion from the upper end of the transport unit 110 to the right can be simultaneously performed.

Accordingly, this will enable a faster tube shrinking process, and eventually maximize productivity.

At this time, if the first caterpillar 161 and the second caterpillar 162 are in contact with the fluid transfer pipe 101, it is also possible to make the heat-shrinkable tube 102 spaced apart from the transfer unit 110 .

In other words, the first caterpillar 161 and the second caterpillar 162 are in contact with some sections of both ends of the fluid transfer pipe 101 (the outer circumferential surface where the heat shrink tube 102 is not wrapped), and heat shrink. The tube 102 may be raised upward by a predetermined distance from the transfer unit 110 .

At this time, when the rotational speed of the first caterpillar 161 is controlled to be greater than the rotational speed of the second caterpillar 162, the fluid transfer pipe 101 is rotated clockwise and translated from the upper end of the transfer unit 110 to the right. Exercises can be performed simultaneously.

In this case, the translational movement in the right direction may be slightly smaller than the transfer speed of the transfer unit 110, but more preferably, if the heat-shrinkable tube 102 is spaced apart from the upper portion of the transfer unit 110, the operation of the transfer unit 110 is controlled. It might be good to temporarily stop.

However, it may be more preferable to maintain the operation of the transfer unit 110 in preparation for an emergency such as an unexpected descent of the fluid transfer pipe 101 .

On the other hand, as described above, if the first caterpillar 161 and the second caterpillar 162 are in contact with the fluid transfer pipe 101, the heat shrinkable tube 102 is spaced apart from the transfer unit 110. When the rotation speed of the second caterpillar 162 is temporarily controlled to be greater than the rotation speed of the first caterpillar 161 in , and this may be a reverse operation. Such a reverse operation may be used as a process for removing the fluid transfer pipe 101 incorrectly inserted into the heating device 100, for example, a pure pipe in which the heat shrink tube 102 is not wrapped at all, is incorrectly inputted. There will be.

On the other hand, in order to check whether the fluid transport pipe 101 in which the heat-shrinkable tube 102 is properly wrapped is inserted, a first inspection sensor (not shown) for testing the heat-shrinkable tube 102 may be provided at the inlet (in) side. will be.

In addition, it would be good to provide a second inspection sensor (not shown) for checking whether the heat-shrinkable tube 102 is properly contracted on the outlet side.

Accordingly, a more sophisticated tube shrinking process becomes possible, and in the end, quality improvement due to reduction in defects can be maximized.

On the other hand, the conveying speed control unit 201 reduces the conveying speed of the conveying unit 110 when the measured temperature measured by the temperature sensing unit 140 is lower than the preset shrinkage temperature range of the heat-shrinkable tube 102, and the measured temperature is contracted. When it is higher than the temperature range, it may be desirable to control the feed rate to increase.

In addition, it is preferable that the heating temperature control unit 202 controls the heating temperature of the heating unit 120 so that the measured temperature measured by the temperature sensing unit 140 satisfies a preset shrinkage temperature range of the heat-shrinkable tube 102 . .

Meanwhile, the heating apparatus 100 according to the fourth preferred embodiment of the present invention may include a second position control unit 204 .

When the measured temperature measured by the temperature sensing unit 140 is higher than the preset shrinkage temperature range of the heat-shrinkable tube 102, the second position control unit 204 increases the height of the heat loss prevention film entrance and the measured temperature is the shrinkage temperature. When it is lower than the range, it is possible to control the heat loss prevention film to minimize the height of the entrance.

This is because, when the internal temperature of the heating device 100 increases rapidly, it is necessary to discharge the internal temperature of the heating device 100 to the outside by using a physical means for rapid temperature reduction.

That is, the upper end of the first heat loss prevention film 151 is rotatable in the housing of the heating apparatus 100 , and the upper end of the second heat loss prevention film 152 is also provided rotatably in the housing of the heating apparatus 100 .

In more detail, one end of the first heat loss prevention film 151 is rotatably connected to the heating device 100 at the inlet side end, and the other end is a free end.

One end of the second heat loss prevention film 152 is rotatably connected to the heating device 100 at an outlet side end, and the other end is a free end.

When the temperature inside the heating device 100 measured by the temperature sensing unit 140 rapidly increases and is greater than a preset value, the second position control unit 204 controls the first heat loss prevention film 151 to rotate. can do.

That is, the end of the first heat loss prevention film 151 is raised in a direction away from the indoor space of the heating device 100 , so that the inlet can be largely opened.

At the same time, the end of the second heat loss prevention film 152 is also raised in a direction away from the indoor space of the heating device 100 to greatly open the outlet.

As a result, as the inlet (in) and the outlet (out) are opened larger, respectively, the heat inside the heating device 100 can be rapidly discharged to the outside through them, so that the temperature inside the heating device 100 is rapidly lowered. be able to

In other words, the effect of lowering the internal temperature of the heating device 100 due to an increase in the volume of the upper space inside the heating device 100 and the inflow of outside air may be exhibited.

On the other hand, the first heat loss prevention film 151 and the second heat loss prevention film 152 change the size of the inlet (in) and the outlet (out) according to the diameter of the transfer unit 110 passing through the heating device (100) It may also be operated to do so.
