[0008] In addition, a sealing material sticking apparatus according to the present invention includes a holding jig for holding an object to be stuck and a jig for holding the object around the center axis while maintaining the center axis of the object to be stuck at a predetermined position. A rotating means for rotating a holding jig holding an object to be adhered, and a continuous sealing material formed by temporarily and intermittently temporarily attaching a sealing material to an elongated peeling sheet are coated with a rotating member. A transfer means for transferring at the same speed as the rotation of the attached object, and a peeling sheet of the continuous seal material, which is disposed near the attached object and is transferred by the transfer means, is folded back, and only the seal material is substantially By moving straight, the peeling means for peeling off the sealing material from the peeling sheet and feeding out the to-be-attached object in the body circumferential direction, and for the rotating to-be-attached object, the sealing material fed out by the peeling means. Its longitudinal direction Preferably includes a bonding means for pressing over from one end to the other end.

Further, in this sealing material sticking apparatus,
The rotating means includes a driving motor for rotating the holding jig, and the driving force of the driving motor is transmitted to the transferring means via the clutch in order to transfer the sealing material continuous body in conjunction with the rotation of the holding jig. Then, it is preferable that after one sheet of the sealing material is peeled and fed, the connection of the clutch is disconnected and the transfer of the continuous sealing material is stopped.

Further, in this sealing material sticking apparatus, the heating means is such that the heat-shrinkable sealing material for shrink wrapping is wound around a portion of the object to be stuck to which the sealing material extending in the body circumferential direction is to be stuck. It is preferable that the heating of the sealing material be started after being stuck as described above, and the heating be stopped after at least one rotation of the container.

[0013]

According to the sealing material sticking apparatus of the present invention,
A heat-shrinkable sealing material having a predetermined width is wound around the object so as to be wound around the object, and the object can be shrink-wrapped by subsequently heating the sealing material.

Further, according to the sealing material sticking apparatus of the present invention, the object to be stuck is held by the holding jig.
In this case, a portion to which the sealing material extending in the body circumferential direction of the object 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. When the holding jig rotates, the adhered object held by the holding jig also rotates around the central axis while keeping its central axis at a predetermined position. Next, the sealing member continuum is transferred by the transfer unit at the same speed as the rotation speed of the adhered object. Then, the peeling means peels off the sealing material from the peeling sheet of the continuous sealing material and feeds out the sticking object in the body circumferential direction. At the same time, the sealing member is pressed from one end to the other end in the longitudinal direction of the object to be rotated by the applying means, and is applied so as to be wound around the object in the circumferential direction of the object. .

Further, in this sealing material sticking apparatus,
When a drive motor and a clutch are included, the driving force of the drive motor is transmitted to the transfer means via the clutch. Due to the transmitted driving force, the seal material continuum is transferred in conjunction with the rotation of the holding jig, that is, the rotation of the adhered object. Then, after one sealing material is peeled and fed, the connection of the clutch is disconnected, and the transfer of the continuous sealing material is stopped.

Further, in the case where the sealing material applying apparatus includes a heating means, the sealing means is heated and shrunk by heating the heat-shrinkable sealing material by the heating means, so that the adherend is shrink-wrapped. .

When the heating means includes a housing having an air outlet, an air blower and a heater, the air blown by the air blower is
Heated by a heater. The heated air is blown from the blower port toward the sealing material to heat the heat-shrinkable sealing material.

If the sealing material is heated and shrunk in the course of being applied to the object, the application of the sealing material tends to be incomplete. Therefore, in the present invention, the heating of the sealing material is started after the sealing material is completely attached so as to be wound around the object, and the heating is stopped after the object is rotated at least once. By doing so, heating can be performed uniformly over the entire length of the sealing material, and heat shrinkage of the sealing material can be performed uniformly and reliably.

[0019]

According to the sealing material sticking apparatus of the present invention,
The sealing material can be securely and efficiently attached by being wound around the to-be-attached object in the circumferential direction of the to-be-attached object, and the to-be-attached object can be sealed.

Further, according to the sealing material sticking apparatus of the present invention, a highly versatile heat-shrinkable sealing material is wound around the object to be stuck and then heated to shrink-wrap the object to be stuck. It is possible to cope with objects having various outer diameters. Therefore, as compared with the conventional preform type shrink cap, it is more suitable for shrink packaging of a small lot, and it is easy to cope with high-mix low-volume production.

Further, according to the sealing material sticking apparatus of the present invention, the object to be stuck is held and rotated by the holding jig. It can be applied to objects.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention with reference to the accompanying drawings.

The first pulley 104, the second pulley 108, and the clutch pulley 92 have a transmission belt having a rectangular cross section for transmitting the driving force of the driving motor 102, as shown by a dashed line in FIG. 112 is passed over.
On the front and back surfaces of the transmission belt 112, tooth-like irregularities of the gear are formed. Gear-shaped teeth are also 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 way, slippage of the transmission belt 112 is prevented, and the timing of rotation can be easily set. 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.

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 take-up roller 52 extends through the first substrate 16 toward the upper plate 12a (downward). The fourth pulley 120 is fixed to the tip. Third pulley 1
18 and the fourth pulley 120, there is a second circular section.
Transmission belt 122 is wound. Therefore, the winding roller 52 rotates in conjunction with the rotation of the transfer roller shaft 44. However, since the transfer of the release sheet S is performed 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 22, the take-up force of the take-up roller 52 is reduced by using a belt having a circular cross section that easily slips.

Next, an electric system of the sealing material applying apparatus 10 will be described. A power supply circuit (not shown) and a control circuit (not shown) are housed inside the outer case 12. The power supply circuit is connected to an external power supply and a control circuit,
Supply power to control circuits and other components. The control circuit is
Sealing material detection sensor 34, heating device 72, clutch 9
0, the drive motor 102, the operation switch 114, and the timer 116.

Next, the sealing material sticking device 10 of this embodiment
The operation situation of will be described. 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 for starting the rotation of the container A is turned on. 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. In addition, the first pulley 104, the second pulley 108, the clutch pulley 92, The diameters and the like of the gears 58b and 110 are formed.

When the holding jig 58 rotates, the container A is rotated together with the holding jig 58 while holding the center axis at a predetermined position. At the same time, when the transfer roller 42 is rotated, the sealing material continuous body 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 of the container A and the lid A2. The fed-out sealing material L is sequentially pressed and adhered by the pressing roller 40 so as to cover the boundary between the body A1 and the lid A2 of the container A as shown in FIG.
After one sheet of the sealing material L is completely peeled off from the sealing material continuous body R and is fed out, the next sealing material L is detected by the sealing material detection sensor 34. The control circuit receiving the signal 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 rotation of the transfer roller 42 and the take-up roller 52 is stopped, and the transfer of the sealing material continuous body R is stopped.

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

By being heated by the heating device 72, the sealing material S is contracted by heating in the longitudinal direction as shown in FIGS.
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 rotates a predetermined number of times (at least once), the sealing material L sufficiently heat-shrinks, and the shrink wrapping is completed, the heating and the rotation are stopped. This timing also
Measured by the control circuit.

When holding or removing the container A as an object to be stuck, the first substrate 16 is rotated about the transfer roller shaft 44 by operating the operation lever 88, and the two-dot chain line is shown in FIG. This is performed after separating the peeling plate 30 from above the container A as shown by. The holding jig 5
When the handle 8 is replaced to fit the container A, the handle 100 is moved as shown by a two-dot chain line in FIG. Is performed after shifting the position.

As described above, according to the sealing material applying apparatus 10, the sealing material L is securely and efficiently applied so as to be wrapped around the container A as an object to be applied in a torso circumferential direction, and the container A is hermetically sealed. can do. In addition, according to the sealing material sticking apparatus 10, after a highly versatile heat-shrinkable sealing material is wound around the object to be stuck,
Since the object to be bonded is shrink-wrapped by heating, it is possible to cope with the object to be bonded having various outer diameters. Further, according to the sealing material sticking apparatus 10, the holding jig 58
Since the container A as the object to be attached is held and rotated, it can be applied to an object to be attached of the body A1 having any shape such as a cylindrical shape or a rectangular tube shape.

Further, according to the sealing material sticking apparatus 10, anyone can easily perform shrink wrapping. The container A is heated by the heat-shrinkable sealing material L.
Cover A2 and body A1 can be fastened and sealed so as not to easily come off. Further, the sealing material sticking device 10 is small, does not take up a mounting space, and is relatively easy to carry. Furthermore, since a heat-shrinkable sealing material is applied and then heat-shrinkable, a preforming process such as a conventional shrink cap is not required. For this reason, the present invention is suitable for shrink packaging of small lots, and can easily cope with high-mix low-volume production.
