Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for packaging spools of cheese, paan, etc. with plastic film sheets, which is suitable for carrying out in a continuous processing line for spools of spools. .

[Prior Art] Conventionally, in a continuous processing line for thread rolls, wrapping thread rolls such as cheese and paan with plastic film sheets is known, for example, as disclosed in Japanese Patent Publication No. 55-34059.

[Problem to be Solved by the Invention] However, in this known packaging, the side circumference of the bobbin body is covered with a plastic film sheet having a width sufficient to cover the entire outer circumferential surface of the bobbin bobbin body supported on a tray in an upright state. In addition to covering the film sheet, the upper and lower parts of the film sheet (near the upper and lower ends of the bobbin body) are nipped and welded with spot sealers, and the bobbin bobbin body is packaged by welding several spots. For this reason, there were various drawbacks such as insufficient sealing performance and difficulty in removing the packaging in a subsequent process.

The present invention has focused on such a problem, and as a result of intensive studies from various aspects in order to solve this problem, it has been found that it is sufficient to replace the conventional spot sealer type film sheet welding with an air intake type film sheet folding mode. It was.

[Means for Solving the Problems] That is, the plastic film packaging method for a thread-wound body according to the present invention is constructed by erecting pegs on a disk, and has an opening at the lower surface of the disk and the upper end of the peg. A tray having a hole with a small diameter at the upper end of the peg and supporting the thread winding body by inserting the upper end small diameter part into the hollow part of the thread winding body is inserted into the air intake port of a tray support plate having air intake ports opened on both upper and lower sides. a plastic film sheet having a width sufficient to cover the entire outer peripheral surface of the thread wound body supported by the positioned tray; a step of covering the side peripheral surface of the thread wound body; a step of suction-folding the upper end of the plastic film sheet covering the side peripheral surface of the thread winding body by suctioning air from the air intake port into the hollow portion; A chuck claw is inserted into the hollow part in which the upper end of the plastic film sheet is folded in, grips the bobbin body, and moves it upward, and the lower end of the plastic film sheet is sucked into the hole through the intake port. positioning the plastic film sheet at a height that allows it to be folded in by suction, and then, after the lower end of the plastic film sheet is folded into the hole by the suction air, the thread roll is moved downward and supported on the tray again. The method is characterized in that it consists of a step of forcing.

The basic flow of the packaging method according to the present invention will be described below.
2 indicates a thread body such as cheese wrapped with a thread, 2 indicates a tray, and 3 indicates a tray support plate, and tray 2 is
Consisting of pegs 5 set up on a circular disk 4,
It has a hole 6 that opens to the lower surface of the disc 4 and the upper end of the peg 5, and the small diameter part of the upper end of the peg 5 is inserted into the hollow part 7 of the bobbin body 1 to support the bobbin bobbin body 1. There is.

On the other hand, the tray support plate 3 is horizontally mounted via a suitable frame (not shown), and has intake ports 8 opening on both the upper and lower sides thereof, and has an intake port 8 aligned with the intake port 8 on its lower surface. The above-mentioned tray 2 is transported via a pair of intermittent transport mechanisms 23a and 23b as shown in the embodiments described later, and the tray 2 is transported to the intake port 8 of the tray support plate 3. The hole 6 is positioned so as to align with the hole 6. In FIG. 1, this positioning mode is shown.

Subsequently, the side peripheral surface of the bobbin body 1 supported by the positioned tray 2 is moved, for example, by a pair of pusher devices 37 as shown in the embodiment described later.
a, 37b, the plastic film sheet 10 is provided with a width sufficient to cover the entire outer peripheral surface of the bobbin body 1, as shown in FIG. After the side peripheral surface of the bobbin body 1 has been covered with the plastic film sheet 10, a suction fan (not shown) to which the duct 9 is connected is then activated, and air is taken in from the inlet port 8.

Then, outside air is sucked in from the upper end surface of the thread winding body 1 through the hollow part 7 of the thread winding body 1 and the hole 6 formed in the tray 2, and as a result, the upper end part A of the plastic film sheet 10 moves into the hollow part 7. It is sucked inward. FIG. 2 shows a state in which the upper end portion A of the plastic film sheet 10 is suction-folded into the hollow portion 7 in this manner.

Subsequently, the chuck claw 12 of the chuck device 11 is inserted into the hollow portion 7 into which the upper end portion A of the plastic film sheet 10 is folded, and the bobbin body 1 is grasped. The chuck device 11 is suspended on a ceiling frame (not shown), and is provided so that the chuck claws 12 can be moved up and down, and the chuck device 11 can also expand and collapse the plurality of claws constituting the chuck claws 12. It is provided in a so-called split chuck so that it can be used.

Therefore, the chuck pawl 12 is inserted into the hollow portion 7 with the pawls in the collapsed state, and the bobbin body 1 can be gripped by expanding the pawl group, and after gripping, the chuck pawl 12 is moved upward. By doing so, the bobbin body 1 can be moved above the tray 2. FIG. 3 shows a state in which the bobbin body 1 is moved above the tray 2 in this manner.

The upward movement of the bobbin body 1 is such that the lower end of the plastic film sheet 10 is positioned at a height such that it can be sucked and folded into the hole 6 of the tray 2 by sucking air through the air intake port 8. It will be done. Note that this height may be either slightly above the upper end of the tray 2 or slightly below the upper end of the tray 2. Although it varies depending on various conditions such as the difficulty of deforming the plastic film sheet 10, the size of the outer diameter of the bobbin body 1, the strength of the intake force from the intake port 8, and the size of the inner diameter of the hole 6, in general,
10cm above the top of tray 2 as a reference
Hereinafter, the downward range is preferably 20 cm or less.

Next, in this state, when the suction fan is started and air is taken in from the intake port 8, the outside air from the lower end surface of the bobbin body 1 is sucked through the hole 6 formed in the tray 2, and thereby the plastic The lower end of the film sheet 10 is sucked and folded into the hole 6. This embodiment is also shown in FIG.

Next, the chuck claw 12 is moved downward to insert the small diameter portion of the upper end of the tray 2 into the hollow portion 7 of the bobbin body 1. At this time, the upper end of the tray 2 presses the lower end portion of the plastic film sheet 10. The thread body 1 is then folded into the hollow portion 7, so that the entire outer circumferential surface of the bobbin body 1 can be covered, that is, wrapped, with the plastic film sheet 10, as shown in FIG.

In this way, the present invention uses a tray that supports and transfers the spool in an upright position, and a chuck claw that handles the spool by utilizing the hollow part of the spool. Since the upper and lower ends of the spool are folded into the hollow part of the bobbin body using the suction method, packaging is done quickly and easily, and the sealing property is sufficiently maintained to effectively prevent the intrusion of dust, etc. In addition, it is possible to easily handle the spool after packaging, and it is also possible to handle spools of different sizes.Furthermore, when removing the packaging in a later process, the axis of the spool can be easily handled. The present invention provides a plastic film packaging method that can be easily removed from either side in the direction of the thread, and the thread can be easily pulled out during winding, for example, and is therefore suitable for implementation in a continuous processing line for wound bodies. Obtainable.

[Example] In FIG. 5, which is a plan view, and FIG. 6, which is a right side view of FIG. However, this tray support plate 3 is fixed to the center of the upper end surface of the apparatus frame 20. In addition, a pair of presser guides 21 are fixed to the left and right ends of the upper end of the device frame 20, but the tray 2
is guided and conveyed by side guides 22 fixed to this presser guide 21. Note that this conveyance is performed via a pair of intermittent conveyance mechanisms 23a and 23b that are configured identically.

That is, the tray 2 supporting the bobbin body 1 from the previous process by a conveyor device (not shown) is fed onto one end (the left end in FIG. 5) of the tray support plate 3, and then the second tray 2 is fed onto the tray support plate 3. When fed onto the plate 3, the disk 4 of the tray 2, which is provided with a larger diameter than the diameter of the bobbin body 1, comes into contact with the disk 4 of the tray 2 that was fed first, and is pushed and transferred. The tray 2 supplied first is placed in the tray receiver 24a of the intermittent transport mechanism 23a, 23b.
(place A shown in Figures 5 and 7)
will be moved to. Note that FIG. 7 is a left side view of FIG. 6, and in this figure, one of the intermittent conveyance mechanisms 2
The detailed structure of 3a is shown.

Next, the air cylinders 25 of the intermittent transport mechanisms 23a and 23b are activated simultaneously to project their piston rods upward. Then, both feed bars 26
is moved upward, and therefore, the tray 2 is supported by the tray receiver 24a and lifted up, and separated from the tray support plate 3. In addition, at this time, tray 2
is lifted to a position where the upper surface of the disc 4 does not come into contact with the presser guide 21.

Subsequently, the air cylinders 27 of the intermittent conveyance mechanisms 13a and 13b are activated simultaneously to project their piston rods in the horizontal direction. As a result, both the feed bars 26 are moved horizontally to the right, and the tray 2
is moved from location A to location B in the diagram. Further, the piston rods of both air cylinders 25 are depressed downward, and the tray 2 is again supported by the tray support plate 3. After that, the piston rods of both air cylinders 27 were also sunk, and both feed bars 26
is moved to its original position.

In this way, move the tray 2 from point A to point B in the illustration.
It can be transported to the location B and can also be transported from the location B to the location C, but this transportation is performed intermittently. In other words, each time packaging is completed at location C in the diagram, it is transported to the subsequent process and transferred from location B to C.
At the same time, it is carried out from A to B. Please note that tray 2 is moved to the location C shown in the diagram.
is positioned so that the hole 6 of the tray 2 is aligned with the intake port 8 of the tray support plate 3.

At this time, as shown by the chain lines in FIG. The film sheet 10 is pulled by the bobbin body 1 conveyed from a location B to a location C and pulled out downstream in the conveyance direction.

Both film support mechanisms 28a and 28b are composed of a film unwinding shaft 29, a drive supply roller 30, a nip roller 31, a dancer roller 32, guide rollers 33 and 34, and a pinch roller 35, which are mounted vertically. The film sheet 10 is provided with a width sufficient to wrap both the upper and lower end surfaces of the bobbin body 1.

Note that when the plastic film sheet 10 is pulled out downstream in the conveying direction as shown in FIGS. 8 and 9, the upper end portion A tends to fall inward, but the plastic film sheet 10 is injected from the pair of nozzles 36a and 36b. This is prevented by the use of compressed air. Pressurized air is injected from both nozzles 36a and 36b at all times, and when the plastic film sheet 10 is moved, it is prevented from moving downward, that is, from being displaced.

Subsequently, the transported bobbin body 1 is wrapped at a location C in the figure, and this is done via a pair of pusher devices 37a and 37b. When the plastic film sheet 10 is pulled out downstream in the transport direction by the bobbin body 1, as shown in FIG.
Although the head 38 of FIG. b has been retracted to the position shown in the figure, the air cylinders 39 (see FIG. 10) of both the pusher devices 37a and 37b are operated simultaneously, and the piston rods thereof are projected, so that both heads 38 are moved to the position shown in the figure. The body is moved onto the transport path.

In FIG. 5, both heads 3
8 is shown moved onto the spool transport path. At a point near the rear end of the bobbin body 1 transferred to the location C, the plastic film sheet 10 is nipped through both heads 38 and cut and welded, that is, the bobbin bobbin body 1 is cut and welded as shown in FIG. The side peripheral surface of the plastic film sheet 10
covered with.

Note that the head 3 of one pusher device 37a
8 is equipped with a ribbon heater 40, but the head 38 of the other pusher device 37b is not equipped with this.Other than this point, both pusher devices 37a and 37b have the same structure. Although not shown, a pair of pusher-type film holding devices are provided to prevent the cut and welded plastic film sheet 10 covering the side circumferential surface of the bobbin body 1 from moving downward.
That is, a device is provided which is configured to press the presser foot against the side of the bobbin body 1.

Next, after finishing covering the side circumferential surface of the bobbin body 1,
A suction fan (not shown) to which the duct 9 is connected is activated and air is sucked in from the intake port 8, so that the upper end of the plastic film sheet 10 covering the side surface of the bobbin body 1 is moved into the hollow portion 7. It is sucked into and folded into. This embodiment is illustrated in FIG. Note that when the upper end A of the plastic film sheet 10 is sucked and folded into the hollow part 7, the film holding by the film holding device is released, and the tray 2 supporting the thread wrapper 1 is moved from a position C (not shown). It is transported downstream by a transport device.

Hereinafter, as described above based on FIG. 3, when the chuck claw 1 of the chuck device 11 is
2, the bobbin body 1 is moved upwards, and then
The lower end part B of the plastic film sheet 10 is sucked and folded into the hollow part 7 by the intake air from the intake port 8, and further, by the downward movement of the chuck claw 12, the bobbin body 1 is supported by the tray 2 again, and thus The entire outer peripheral surface of the bobbin body 1 can be covered with a plastic film sheet 10, that is, wrapped.

One embodiment of the present invention has been described above, but in the present invention, the thread body is made of a material other than cheese.
For example, it may be a paan or the like.

[Effects of the Invention] As described above, according to the present invention, it is possible to quickly and easily package a bobbin body in a manner that sufficiently seals the package and prevents dust from entering. In addition, it is possible to easily handle the spool body after packaging, and it is also possible to handle spool bodies of different sizes.Furthermore, when removing the packaging in a later process, it is possible to easily handle the spool body after packaging, and furthermore, when removing the packaging in a later process, it is possible to easily handle the spool body after packaging. For example, the yarn can be easily removed from the plastic film during winding, etc. Therefore, a plastic film packaging method suitable for implementation in a continuous processing line for wound bodies can be obtained. .
