[0013]

According to the sealant sticking device of the invention,
A heat-shrinkable sealing material having a predetermined width is attached to an adherend such that the sealant is wound around the adherend, and the sealant is subsequently heated to shrink-wrap the adherend.

Further, according to the sealing material sticking apparatus of the present invention, the sticking object is held by the holding jig.
In this case, the portion to which the sealing material, which extends in the circumferential direction of the object to be attached, is to be attached is exposed from the holding jig so that the sealing material can be attached. Next, the holding jig is rotated by the rotating means. As the holding jig rotates, the adherend held by the holding jig also rotates around the central axis while keeping the central axis at a predetermined position. Next, the transfer material transfers the continuous body of sealing material at the same speed as the rotating speed of the adherend. Then, the sealing material is peeled off from the release sheet of the continuous sealing material by the peeling means and is fed in the circumferential direction of the adherend. At the same time, the sticking means presses the sealing material from one end to the other end in the longitudinal direction of the sticking object that is rotating, and sticks the sticking material around the sticking object in the circumferential direction. .

It is heated by the heater. The heated air is blown from the blower port toward the sealing material in order to heat the heat-shrinkable sealing material.

If the sealing material is heated and shrunk while being attached to the adherend, the attachment of the sealing material tends to be incomplete. Therefore, in the present invention, the sealing material is completely attached so as to wind around the adherend, and then the heating of the seal material is started, and the heating is stopped after the adherend makes at least one rotation. By doing so, it is possible to uniformly heat the entire length of the sealing material, and it is possible to uniformly and reliably heat-shrink the sealing material.

[0019]

According to the sealing material sticking device of the present invention,
The sealing material can be reliably and efficiently applied by wrapping it around the to-be-applied object in the circumferential direction, and the to-be-adhered object can be sealed.

Further, according to the sealant sticking device of the present invention, since a heat-shrinkable sealant having high versatility is wrapped around an object to be stuck and then heated, the object to be stuck is shrink-wrapped. It can be applied to objects with various outer diameters. Therefore, as compared with the conventional preform-type shrink cap, it is suitable for shrink-packing in a small lot, and it becomes easy to cope with small-lot production of various kinds.

Further, according to the sealant sticking apparatus of the present invention, since the sticking object is held and rotated by the holding jig, the sticking of any body such as a cylindrical shape or a square tube shape can be performed. It can also be applied to things.

The first pulley 104 is fixed to one end of 2a.

Further, as shown in FIG. 6, the second substrate 94
A cylindrical second protrusion 94b is formed on the other end side in the longitudinal direction of the. Bearings are formed at both ends inside the cylindrical second protrusion 94b. Second protrusion 94b
The drive shaft 106 for rotating the holding jig 58 is rotatably supported by the bearing. The lower end of the drive shaft 106 extends below the second substrate 94, and the second pulley 108 is fixed to the lower end thereof. Also, the drive shaft 10
A drive gear 110 is fixed to the upper end of 6. The drive gear 110 is arranged so as to mesh with the gear 58b of the holding jig 58.

Further, a transmission belt having a rectangular cross section for transmitting the driving force of the drive motor 102 to the first pulley 104, the second pulley 108, and the clutch pulley 92, as indicated by the alternate long and short dash line in FIG. 112 is passed over.
On the front and back surfaces of the transmission belt 112, gear tooth-shaped irregularities are formed. Gear-shaped teeth are formed on the respective surfaces of the first pulley 104, the second pulley 108, and the clutch pulley 92 so as to mesh with the teeth on the front and back surfaces of the transmission belt 112. By engaging the gear-shaped teeth in this manner, slippage of the transmission belt 112 is prevented, and the timing of rotation is facilitated. Also,
In this case, the first pulley 104 and the second pulley 108 are rotated inside the transmission belt 112, and the clutch pulley 92 is rotated outside the transmission belt 112. Therefore, the second pulley 108 rotates in the same direction as the drive shaft 102a of the drive motor 102, and the clutch pulley 92 rotates in the opposite direction.

Further, as shown in FIG. 6, a third pulley 118 is fixed to the transfer roller shaft 44 between the upper plate 12a of the outer box 12 and the first substrate 16. Further, the shaft of the winding roller 52 penetrates the first substrate 16 and extends toward the upper surface plate 12a (downward). Then, the fourth pulley 120 is fixed to the tip thereof. Third pulley 1
Between the 18 and the fourth pulley 120, there is a second cross section having a circular cross section.
The transmission belt 122 is wrapped around. Therefore, the take-up roller 52 is rotated in association with the rotation of the transfer roller shaft 44. However, since the release sheet S is transferred by the transfer roller 42, it is not preferable that the winding force of the winding roller 52 becomes too strong. Therefore, in this embodiment, the second transmission belt 1
As the belt 22, a belt having a circular cross section that easily slips is used to weaken the winding force of the winding roller 52.

Next, the electrical system of the sealant sticking device 10 will be described. A power supply circuit (not shown) and a control circuit (not shown) are housed inside the outer box 12. The power supply circuit is connected to the external power supply and control circuit,
Supplies power to control circuits and other components. The control circuit
Seal material detection sensor 34, heating device 72, clutch 9
0, the drive motor 102, the operation switch 114, and the timer 116 are electrically connected.

Next, the sealant sticking apparatus 10 of this embodiment
The operating status of is explained. First, as shown in FIG. 1, the container A is placed in the storage portion 58c of the holding jig 58 such that the boundary between the body A1 and the lid A2 to which the sealing material L is to be attached contacts the front surface of the pressing roller 40. It is inserted and held by the holding jig 58. Next, the operation switch 114 connected to the control circuit is turned on to start the rotation of the container A. Then, the drive motor 102 rotates, and the holding jig 58 holding the container A is rotated clockwise in FIG. At the same time, the transfer roller 42 and the take-up roller 52 are each rotated clockwise. The first pulley 104, the second pulley 108, the clutch pulley 92, so that the sealing material continuum R can be transferred and the sealing material L can be fed at a speed substantially the same as the rotation speed of the container A. The diameters of the gears 58b and 110 are formed.

When the holding jig 58 is rotated, the container A is rotated together with the holding jig 58 while holding the central axis of the container A at a predetermined position. At the same time, when the transfer roller 42 is rotated, the sealing material continuum R is sequentially transferred. Then, the sealing material L is peeled off by the peeling plate 34, and is fed toward the boundary between the body A1 and the lid A2 of the container A. As shown in FIG. 10A, the rolled-out sealing material L is sequentially pressed and applied by the pressing roller 40 so as to cover the boundary between the body A1 and the lid A2 of the container A.
After one sealing material L is completely peeled from the sealing material continuum R and fed out, the next sealing material L is detected by the sealing material detection sensor 34. Upon receiving the signal, the control circuit sends a signal to the clutch 90 to disconnect the clutch 90 from the rotation of the clutch pulley 92. Then, the rotation of the transfer roller shaft 44 is stopped, the rotations of the transfer roller 42 and the take-up roller 52 are stopped, and the transfer of the seal material continuous body R is stopped.

The container A continues to rotate as the holding jig 58 rotates. Along with the rotation, as shown in FIG. 10 (A), the seal material L is attached by the pressing roller 40 around the boundary between the body A1 and the lid A2 of the container A so as to wind around. Then, after the container A has been pasted at least one rotation and the sealing material L has been attached over its entire length, heating by the heating device 72 is started as shown in FIG. 10 (B). That is, heating of the sealing material L is started by transmitting power to the heating device 72 after a predetermined time has elapsed since the next sealing material L was detected by the sealing material detection sensor 34. This timing can be set by the operator by the timer 116 and measured by the control circuit.

By being heated by the heating device 72, the sealing material S is heated and shrunk in the longitudinal direction as shown in FIGS. 10 (C) and 10 (D), and the body A of the container A is compressed.
It comes into close contact with the boundary between 1 and the lid A2. This heating is performed uniformly while rotating the container A. Then, when the container A is rotated a predetermined number of times (at least once), the sealing material L is sufficiently heat-contracted, and the shrink wrapping is completed, the heating and the rotation are stopped. This timing is also
Measured by the control circuit.

When holding or removing the container A which is the object to be adhered, the first lever 16 is rotated around the transfer roller shaft 44 by operating the operation lever 88, and the two-dot chain line is shown in FIG. The peeling plate 30 is moved away from the top of the container A as shown in FIG. Also, the holding jig 5
8 is replaced to fit the container A, the handle 100 is moved as shown by the chain double-dashed line in FIG. 8 to disengage the drive gear 110 and the gear 58b, and the first support roller 60 is moved. It is performed after shifting the position of.

As described above, according to the sealing material sticking device 10, the sealing material L is tightly and efficiently stuck by being wrapped around the circumference of the container A, which is the object to be stuck, reliably and efficiently, and the container A is hermetically sealed. can do. Further, according to this sealant sticking device 10, after sticking a highly versatile heat-shrinkable sealant around an adherend,
Since the adherend is shrink-wrapped by heating, the adherend having various outer diameters can be dealt with. Further, according to the sealing material sticking device 10, the holding jig 58
Since the container A, which is the object to be adhered, is held and rotated, it can be applied to the object to be adhered having a body A1 of any shape such as a cylindrical shape or a rectangular tube shape.

Further, according to the sealant sticking device 10, anyone can easily shrink-wrap. Then, the container A is heated by the heat-shrinkable sealing material L.
The lid A2 and the body A1 can be fastened and sealed so as not to easily come off. Further, the sealing material sticking device 10 is small in size, does not occupy a mounting space, and is relatively easy to carry. Furthermore, since a heat-shrinkable sealing material is applied and then heat-shrinked, a preforming step such as the conventional shrink cap is unnecessary. Therefore, the present invention is suitable for shrink packaging of small lots, and can easily cope with small lot production of various kinds.
