Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film packaging device for a yarn package.

[0002]

2. Description of the Related Art Conventionally, various types of so-called film packaging for packaging a yarn package with a thermoplastic synthetic resin film are known. For example, in Japanese Examined Patent Publication No. 55-34059, a yarn package is conveyed (or transferred) in an upright state and packaged (hereinafter referred to as vertical packaging).
Is disclosed. In addition, for example, Japanese Patent Publication No. 53-1
Japanese Patent No. 2230 discloses a device that is transported (or transferred) and is packaged in an overturned form (referred to as horizontal packaging).

[0003]

However, the vertical packaging is
When the yarn wound around the hollow bobbin is easy to be loosened (for example, in the case of carbon fiber etc.), it is difficult to prevent it and therefore it is difficult to adopt. Therefore, in the case of easy-to-remove yarn, in general,
The latter horizontal packaging was adopted.

However, in this packaging, as described above, since the yarn package is conveyed (or transferred) in an overturned state, the yarn is supplied to a conveyor or the like which is such conveying (or transferring) means. Since it was difficult to prevent them from coming into contact with each other, it was unavoidable to ignore the contact with the yarns in some of the processes, but this caused damage to the package surface due to rubbing and package shoulders. Since dents and the like are likely to occur, further improvement has been required for these points. In addition, a trouble is likely to occur when the yarn package is transferred from one conveying (or transferring) means to the other, and the cargo handling speed is also poor.

The present invention has been made in view of these drawbacks.
As a result of diligent studies to eliminate these problems, a package cargo handling device that supports both ends of the hollow bobbin of the yarn package positioned at the loading position and transfers it to the sealing position in the overturned state Insert the clamps into the openings on both ends of the hollow bobbin and move the clamp device group supporting the yarn package in one direction around the uniaxial direction one by one to move from the loading position to the loading position through the sealing position and the standby position. It has been found that the above-mentioned drawbacks can be solved all at once by constructing the device so that it can be returned.

[0006]

[Means for Solving the Problems] That is, a film packaging apparatus for a yarn package according to the present invention is a first conveyor for supporting both ends of a hollow bobbin of a yarn package in an overturned state and carrying out tact conveyance at regular intervals. A device, a package positioning device for supporting both ends of the hollow bobbin of the yarn package conveyed by the first conveyor device, and positioning the device in a unloading position in a rolled state; and a package positioning device positioned in the unloading position. The package handling device that supports both ends of the hollow bobbin of the yarn package and transfers the yarn package to the sealing position in a laterally rolled state, and the yarn package that is being transferred toward the sealing position is pulled by the yarn package for a certain length. A film tensioning device that vertically stretches the thermoplastic synthetic resin film so that the yarn package can be unwound, and the yarn package is the sheath. A heat sealer device that presses the U-turn upper and lower parts of the thermoplastic synthetic resin film when they are transferred to a position to weld and cut them, and a packaged yarn package that is detached from the package handling device to the next process side. And a plurality of clamping devices for supporting the yarn package by radially inserting the package loading / unloading device into the hollow bobbin of the yarn package. The present invention is characterized in that the clamp device is intermittently moved in one direction centering on one axis so that the clamp device can be sequentially returned from the loading position to the loading position through the sealing position and the standby position.

[0007]

In FIG. 1, the yarn package 1 to be wrapped is conveyed by the first conveyor device 2 to the package handling device 3 side. At that time, the yarn package 1 is tact-transported (intermittently transported) at regular intervals in a state in which both ends of the hollow bobbin 4 are supported and are overturned. Then, the yarn package 1 conveyed to the package loading / unloading device 3 side is positioned at the loading / unloading position A by the package positioning device 5 (see FIGS. 5 and 6) connected to the first conveyor device 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below. In FIG. 1 which is a front view and FIG. 2 which is a right side view of this drawing, this packaging device includes a first conveyor device 2 and a package loading / unloading device. The apparatus 3, the film tensioning apparatus 10, the heat sealer apparatus 12, the second conveyor apparatus 13 and the like are provided.

First, the first conveyor device 2 will be described in detail. In FIG. 3 which is a front view and FIG. 4 which is a plan view of this drawing, the first conveyor device 2 is intermittently operated by a driving device (not shown). The left and right endless chain conveyors 20 that are driven so as to travel in the direction of the arrow in the figure are provided with pushers 21 at regular intervals over the entire length, and the pushers 21 are positioned below the position where they are moved. The hobbin support rail 22 is mounted horizontally.

Therefore, when the worker feeds the yarn package 1 to be wrapped on the hobbin support rail 22 in a state in which the yarn package 1 is turned over from the feed port 23, the hollow bobbin 4 supported by both rails 22 is moved. The pushers 21 of the intermittently driven endless chain conveyors 20 approach and are simultaneously in contact with both ends, and are pushed by the pushers 21 and conveyed to the package handling apparatus 3 side.

The pair of left and right endless chain conveyors 20 are intermittently driven synchronously so that each time the yarn package 1 is supplied onto the hobbin support rail 22, it is driven and stopped for a certain period of time. Therefore, as shown in the plan view of FIG.
The yarn package 1 supplied above is tact-transported (intermittently transported) to the side opposite to the supply port 23 side, and the package positioning device 5 continuously provided on the conveyor device 2.
Is positioned at the delivery position A.

Further, as shown in FIG. 6 which is a front view, the package positioning device 5 swings around a shaft 26 as a fulcrum by a actuator guide 25 and a shutter guide 24 connected to the hobbin support rail 22. And a swing guide 27 that is mounted so that the shock guide 24 forms a V-shaped recess 24b that is continuous with the descending inclined surface 24a.

Therefore, the yarn package 1 transferred from the hobbin support rail 22 to the shorter guide 24 rolls on the descending inclined surface 24a of the shorter guide 24 and reaches the V-shaped concave portion 24b. As a result, the yarn package 1 is positioned at the delivery position A. At this time, the swing guide 27 in the position shown by the solid line in FIG. 6 prevents the yarn package 1 from being excessively moved in the longitudinal axis direction.

Thus, the package positioning device 5
Can be positioned at the cargo delivery position A while supporting both ends of the hollow bobbin 4 of the yarn package 1 which is tact-transported by the first conveyor device 2 and is in a laterally rolled state.

Next, referring to FIG. 6, the actuator 2
In the state in which the swing guide 27 is swung to the position indicated by the chain line by 5, the yarn package 1 positioned at the load-carrying position A is the package handling device 3
It is supported by the clamp device 8.

As shown in FIG. 2, the package handling apparatus 3 includes left and right side brackets 7 mounted at predetermined intervals on a drive shaft 6 connected to an output shaft of a prime mover 29, and the brackets. 7 and three clamp devices 8 that are radially mounted, and a clamp device 8
Is configured such that the pair of clamps 9 can be moved toward and away from each other, that is, the actuators 28 are attached to the left and right side brackets 7 respectively, and the clamps 9 are attached to the tip ends of the piston rods to control the retracting of the rods. Is configured so that the pair of clamps 9 can approach and separate from each other.

The three clamp devices 8 are mounted at equal intervals, and in FIG. 1, they are respectively located at the delivery position A, the seal position B, and the standby position C. Therefore, in FIG. 5, the clamp device 8 at the loading position A operates the actuator 28 to bring the clamps 9 closer to each other, thereby opening the one end of the hollow bobbin 4 positioned by the package positioning device 5 and facing the other. A clamp 9 can be inserted into the end openings at the same time to support the yarn package 1, and in this way the yarn package 1 can be supported is shown in FIG.

Then, the drive shaft 6 is subsequently rotated by 120 degrees, so that the clamping device 8 supporting the yarn package 1 at the delivery position A is moved to the sealing position B and at the standby position C. The clamping device 8 is moved to the delivery position A. At that time, as shown in FIG. 5, the clamp device 8 moved to the unloading position A is moved in a state in which the clamps 9 are retracted (a state in which they are separated from each other).

On the other hand, the yarn package 1, which is supported by the clamp device 8 and is transferred to the sealing position B, is a thermoplastic synthetic resin film 11 which is vertically stretched by a film tension device 10 in the middle thereof. Therefore, the film 11 is transferred to the sealing position B while pulling the film 11. Therefore, a fixed length of the thermoplastic synthetic resin film 11 is unwound.

The tensioning device 10 has a roll 30.
The upper unwinding device 31 that unwinds the thermoplastic synthetic resin film 11 from a or 30b, and the lower unwinding device 33 that unwinds the thermoplastic synthetic resin film 11 from the roll 32.
Both of the unwinding devices 31 and 33 are equipped with driving nip rollers, dancer rollers, etc. at predetermined positions so that the tension of the film 11 can be controlled to be constant. Further, the thermoplastic synthetic resin films 11 from both the unwinding devices 31 and 33 are welded and joined to each other in advance via a heat sealer device 12 described later.

Subsequently, the yarn package 1 is at the sealing position B.
When transferred to the heat sealer device 12, the heat sealer device 12 is activated to press the upper and lower parts of the U tanne of the thermoplastic synthetic resin film 11 to weld and cut them. That is, as shown in FIG. 2, the heat sealer device 12 includes an upper heat sealer 35 mounted so as to be vertically movable by a pair of actuators 34, and the upper heat sealer 35 so as to face the sealer 35. Lower pair of actuators 3
6 and a lower heat sealer 37 mounted so as to be able to move up and down by means of the upper heat sealer 35.
Is moved downward and the lower heat sealer 37 is moved upward to press the upper and lower portions of the U tanne of the thermoplastic synthetic resin film 11 to weld and cut.

Thus, although the yarn package 1 can be film-wrapped, both heat sealers 35 and 37 are returned to their original positions when the welding cutting is completed. Then, both clamps 9 of the clamp device 8 supporting the yarn package 1 are retracted (moved in the direction away from each other). Therefore, the clamp 9 is simultaneously pulled out from the one end opening and the opposite other end opening of the hollow bobbin 4, and the supported yarn package 1 is freed and drops onto the second conveyor device 13.

Hereinafter, the packaged yarn package is conveyed to the next process side (for example, the heat shrinking process side) by the conveyor device 13, but the second conveyor device 13 is shown in FIG.
In the position between the left and right side brackets 7, and when the clamp device 8 attached to the left and right side brackets 7 is moved together with the side brackets 7, the retracted clump 9 cannot contact. It is set up.

When the packaged yarn package is dropped on the second conveyor device 13 and both clamps 9 are retracted to their original positions, the drive shaft 6 moves in the direction of the arrow shown in FIG. It is rotated 120 degrees. Therefore, during the above-mentioned sealing, the clamp device 8 supporting the yarn package 1 to be subsequently packaged at the delivery position A is transferred from this position A to the seal position B, and the packaged yarn The empty clamp device 8 that has dropped the package onto the second conveyor device 13 is moved from the sealing position B to the standby position C, and the empty clamp device 8 at the standby position C is moved to the delivery position A. To be done.

In this way, the yarn packages 1 that are tact-transported by the first conveyor device 2 and are intermittently positioned at the cargo delivery position A can be film-wrapped one after another. At this time, the yarn package 1 can be transferred in a laterally-overturned state, and further, the both ends of the hollow bobbin 4 can be supported and transferred. Therefore, damages due to rubbing of the package surface, dents of the package shoulder, etc. occur. It is possible to completely eliminate such a drawback of the conventional device that is easy.

Further, the package loading / unloading device 3 is radially mounted with a plurality of clamp devices 8 for supporting the yarn package 1 by inserting the clamps 9 into the openings of both ends of the hollow bobbin 4, and the clamp devices 8 are Since it is configured such that it can be intermittently moved in one direction toward the center of the drive shaft 6 and can be sequentially returned from the delivery position A to the delivery position A through the seal position B and the standby position C, one transfer (or It is possible to eliminate such drawbacks of the conventional device in that a trouble is likely to occur when the yarn package is transferred from the (transportation) means to the other and the speed of the cargo handling is poor.

Although one embodiment according to the present invention has been described above, in the present invention, the heat sealer device 12 is
It may be either type of impulse or fusing seal, and both upper and lower heat sealers 35, 37.
Is preferably mounted so as to be movable in the left-right direction in FIG. 1, whereby the position where the thermoplastic synthetic resin film 11 is welded and cut is set at a predetermined position according to the size of the outer diameter of the yarn package 1. Can be adjusted.

In addition, the first conveyor device 2 and the package positioning device 5 can adjust the pitch for supporting the hollow bobbin 4 of the yarn package 1 to be packaged according to the size of the entire length (FIG. 5, it is preferable to provide a structure capable of sliding in the front-back direction).

By providing the hollow bobbin 4 in this manner, the moving stroke of the clamp 9 can be controlled in a predetermined manner corresponding to the size of the entire length of the hollow bobbin 4 so that the clamp bobbin 4 can be supported and film-wrapped. Can be planned.
In FIG. 3, in order to prevent the yarn package 1 from moving in the left-right direction and coming into contact with the hobbin support rail 22, the yarn package 1 has a dimensional relationship of La <Lb.

[0033]

As described above, according to the present invention, both ends of the hollow bobbin of the yarn package can be supported (conveyed) in a laterally rolled state to be film-wrapped, and
At that time, it is possible to obtain a film packaging device for a yarn package, which enables rapid film packaging while preventing damage to the yarn package and occurrence of cargo handling trouble.
