Description

[Detailed description of the invention] This invention enables flexible and foldable workpieces, especially socks, pantyhose, towels, handkerchiefs, and other textile products, to be wrapped in a roll and easily packaged. The present invention relates to the provision of a new wrapping packaging means.

As is well known, when it comes to packaging textile products such as socks, pantyhose, towels, etc., packaging that folds into a compact size is overwhelmingly used. Even with conventional folding means, the structure and device become complicated, and mistakes often occur during the folding operation. Furthermore, folding may cause some inconvenience as creases and streaks may occur in the product.

In order to solve these problems, the present invention makes it possible to wrap such flexible and foldable workpieces in a roll form, thereby making it possible to package the workpieces in a roll form without creating creases or streaks. By folding it in half, one end is inserted between a pair of parallel rod-shaped bodies and the rod-shaped bodies are rotated together, so that the rod-shaped body is used as a winding core and is wound in a roll shape. By engaging the end with a pair of rod-shaped bodies advancing towards the pair of rod-shaped bodies, the roll-like winding can be performed mechanically under an appropriate winding tension. The device is for wrapping bendable and foldable workpieces such as textile products in a roll shape, and has a pair of workpiece holding rods placed in parallel at regular intervals. The rod-shaped bodies releasably hold one end of the workpiece between them, and in this state, both rod-shaped bodies rotate integrally at that position, thereby winding the workpiece; It has a work-engaging rod-like body disposed substantially parallel to the work-holding rod-like body, and this rod-like body removably engages with the other end of the workpiece when winding up the workpiece, and the workpiece winding member a workpiece feeding member capable of moving forward and backward relative to the workpiece; a workpiece engaging rod of the workpiece feeding member being driven forward and backward with respect to the workpiece winding member; and a mechanism for applying a desired winding tension to the workpiece when winding the workpiece; , a drive motor whose driving force is controlled; and;

The present invention will be described in detail below with reference to the illustrated embodiment. In FIGS. 1 and 2, a workpiece winding member 2 is provided on one side of a machine base 1. The member 2
Although not shown, a pair of rod-shaped bodies 3 and 4 are protruded in parallel from a disk 18 of a holder 17 which is rotatably connected to a winding drive motor 5 via a suitable speed reduction mechanism (not shown). Therefore, motor 5
As the holder 17 rotates, both rod-shaped bodies 3,
4 are provided so as to be rotated as a unit, and in the illustrated example, one rod-shaped body 3 is long and the other rod-shaped body 4
are made short, and both rod-shaped bodies 3 and 4 are parallel to each other with a regular interval in order to insert and support one end of the workpiece. Corresponding to the workpiece winding member 2, a workpiece feeding member 11 is disposed at a position substantially parallel to the workpiece winding member 2 so as to be movable forward and backward toward the workpiece winding member 2. The workpiece feeding member 11 is attached to a holder 19 as shown in the figure.
An arm 21 with one end pivotally supported by a hinge 20 is provided on the upper part of the arm 21, and a rod-shaped body 3,
A rod-shaped body 10 is provided protrudingly parallel to 4.
The holder 19 is attached to a pair of sprockets 14,1
Endless chain 15 stretched between 4 so that it can circulate freely
By being fixed to the drive sprocket 14
Chain 15 with drive motor 13 connected to the side
Through this movement, the workpiece feeding member 11 can move forward and backward toward the workpiece winding member 2.

On one side of the workpiece winding member 2, there is a vertical operation pin 6 for engaging and operating the rod-shaped body 10 of the workpiece transporting member 11. Although not shown, the vertical operation pin 6 is moved up and down by a guide 22 via a spring. A push-down bar 8 is freely elastically supported and is rotatably connected to the rotary solenoid 7 via a bracket 23, and engages with and operates the arm 11 that also holds the rod-shaped body 10. Furthermore, a micro switch 9 is disposed on the side of the push-down bar 8 for controlling the drive motor 5 of the dough wrapping member 2 by engaging with the arm 11'. Further, a micro switch 16 for controlling the retreating position of the rod-shaped body 10 in the member 11 is disposed on the fabric feeding member 11 side.
6 is provided so that its position can be adjusted according to the length of the workpiece. The winding tension applying means will be described later.

Wrapping and packaging of a work in the form of a roll according to the present invention is carried out as follows.

That is, FIG. 3A to FIG. 3E illustrate the case where the pantaste packing 24 is wrapped and packaged in a roll as an example of the applicable workpiece, but as shown in FIG. Workbench 12 installed above
The stockings 24 are placed on the stockings 24 in the stretched state as shown in FIG. 3A, and after inspection, the center line A-A shown in FIG. As shown in FIG. 3B, with the rod-shaped body 10 as an axis, turn the right half of the stockings 24 (the waist portion 25 side) shown in FIG. 3A above the rod-shaped body 10, and It is folded in half on the left half (the toe portion 26 side) in the figure. Using the stockings 24 folded in half as a workpiece,
As shown in FIG. The overlapping ends are inserted and supported so that they protrude about 1 cm to the left as shown in the figure. As described above, the stockings 24 are folded in half, the overlapping ends of which are inserted and supported between the rod-shaped bodies 3 and 4 of the fabric wrapping member 2, and the folded portion is engaged with the rod-shaped body 10 of the fabric feeding member 11. Then, by starting the drive motor 5 for winding through a switch such as a foot switch, the pair of rod-like bodies 3 and 4 in the dough winding member 2 are integrated together through the holder 17 and the disk 18, counterclockwise in the illustrated example. direction, the stockings 24 begin to be wound in a roll around the rods 3 and 4, and at the same time, the rods 1 of the fabric feeding member 11
0 is pulled and transferred by the stockings 24, but the fabric feeding member 11 is moved by the holder 1.
9 to the endless chain 15, and the chain 15 is driven by the drive motor 13, so that the rod-like body 10 can be moved by using the motor 13 or by other means, as will be described later. By controlling the speed at which the dough feeding member 11 moves toward the dough wrapping member 2, winding tension is applied to the rod-like bodies 3, 3 in the dough wrapping member 2.
The so-called "bamboo winding" of the stockings 24 on the stockings 24 is prevented, and a uniform and tight roll-like winding can be obtained under proper winding tension.

As the rolling of the stockings 24 progresses and the rod-shaped body 10 of the fabric feeding member 11 approaches the drive motor 5 of the fabric-wrapping member 2, the arm 21 supporting the rod-shaped body 10 moves onto the vertical operation pin 6. By riding on the same arm 21
is lifted upward about the hinge 20, and this state is as shown in FIG. 3C.
If the winding progresses to the end in the above state, the hinge 2
When a part of the arm 21 lifted up with 0 as the fulcrum comes into contact with the micro switch 9, the rotation of the drive motor 5 is stopped. In this way, the third
As shown in an example in FIG. stockings 2
Step 4: Packaging and removal, such as putting a pot-shaped container with a lid on and pulling it out, are performed. To explain the wrapping operation of the seal film 27 with reference to FIG. , the drive motor 5 is started to increase winding, and a little later than this, the rotary solenoid 7 is activated and the push bar 8 is rotated counterclockwise. Arm 11' supporting body 10
will be forced downward. At this time, due to the pressing of the arm 11', the vertical operation pin 6 compresses the built-in spring and descends, causing additional rotation of the rod-like bodies 3 and 4 and the arm
By pressing 1' (the rod-shaped body 10 also accompanies),
One end of the seal film 27 will be clamped as shown.

The sealing film 27 with one end pressed and clamped in this way is wrapped around the outer peripheral surface of the rolled stocking 24, and the other end of the sealing film 27 is wrapped around one end side of the film 27 with an adhesive tape piece 28. After pasting, the rotation of the winding drive motor 5 is stopped, and the stocking 24 covered with the seal film 27 is pulled out from the rod-shaped bodies 3, 4, and 10 in the axial direction. In addition, when placing the container in a plastic container with a lid, after the final winding of the stocking 24 is completed, the container with the lid removed is inserted into the stocking 24 from one end side of the rods 3, 4, and 10. After the stockings 24 are fitted into the container, the stockings 24 are removed from the rod-shaped bodies 3, 4, 10 together with the container, and the lid is fitted into the opening of the container, allowing the final packaging of the rolled stockings 24 to be carried out freely.

The rotary solenoid 7 is returned to the old position a little after the rotation of the drive motor 5 is stopped, and the push-down bar 8 is retracted, so that the rod-shaped body 10 and the arm 1
1' returns to the old position, and drives the drive motor 13 on the fabric feed member 11 side to return the fabric feed member 11 to the starting position via the holder 19 and the endless chain 15. This return position is controlled by the micro switch 16. However, in this case, it is appropriate that the switch 16 is arranged so that its position is freely adjustable so that it can correspond to the length of the workpiece. In addition, on the dough wrapping member 2 side, in order to make the work easier, the rotation of the pair of rods 3 and 4 is adjusted so that the short rod 3 is at the top and the long rod 4 is at the bottom. Prepare for the next task.

In the present invention, by rotating the pair of rods 3 and 4 in the dough wrapping member 2 that rotates at a fixed position, a workpiece whose one end is inserted between both rods 3 and 4 is placed on the rods 3 and 4. The tension of the workpiece causes the rod-shaped body 10 in the dough feeding member 11 to advance toward the rod-shaped bodies 3 and 4. Therefore, the tension of the workpiece simply causes the rod-shaped body 10 to advance toward the rod-shaped bodies 3 and 4. In the case of free driven transition by only the winding rods 3 and 4 on the winding side, "bamboo winding" occurs, so it is necessary to apply an appropriate winding tension. In applying this winding tension, a means for directly controlling the driving force of the drive motor 13 or a means for indirectly controlling it is employed. An example of the former is the holder 1 of the fabric feeding member 11.
9 is connected to the drive motor 13 of the endless chain 15.
By using a torque motor as the motor 13 and adjusting and changing its torque, the advancing speed of the dough feeding member 11 can be limited, or by using a motor with a brake as the drive motor 13 and adjusting its brake torque. It is easily possible to apply an electric winding tension such as changing the winding speed to limit the advancing speed. As an example of the latter, for example, by using the holder 19 of the fabric feeding member 11 and moving the holder 19 in a straight line. Various means can be freely adopted, such as installing it slidably on a guiding guide bar, etc., intervening a brake structure on the sliding surface of the holder 19 and the guide bar, and applying tension by applying resistance to the holder 19. It is clear that it can be done.

According to the present invention, as shown in FIG. 3E, for workpieces that are flexible and foldable, there is no need for folding packaging in a desired shape, and roll-shaped wrapping packaging without a core is provided. The product 29 according to the invention is extremely advantageous in that it can be easily obtained and provides a new packaging form. In other words, the simple roll form allows a natural packaging form with no folds or streaks to be obtained without any risk of impairing the quality of the workpiece material, and the process is simple, excluding the initial attachment of the workpiece and removal after packaging. For example, it can be processed fully automatically, significantly reducing packaging costs, and can be easily processed in large quantities. In the case of folding, many complicated mechanisms are required to mechanize it, but according to the present invention, the fabric wrapping member 2 rotates in a fixed position, and the fabric feeding member can move forward and backward toward it. 11
The drive motor 13 etc. is sufficient, and by controlling the drive force of the drive motor 13, the necessary winding tension can be provided without any problem, which is extremely advantageous for work packaging such as long fiber products. It is large in size, requires minimal packaging materials, and eliminates the need for auxiliary paper and shaped pieces. In addition, the workpiece winding tension can be adjusted according to the type of workpiece and the winding shape, and when starting workpiece winding,
By adjusting the distance between the workpiece feeding member and the workpiece winding member, changes in the length of the workpiece to be wound can be accommodated.
