Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging material pulling device for a compression packing machine for textiles, etc.

[Conventional technology]

FIGS. 1 to 6 show an example of a conventional compression packing operation. First, as shown in FIG. 1, fibers 2 to be compressed and packed are packed into a box 1 that is open at the top and bottom. On the other hand, as shown in FIG. 2, the upper compression plate 4 attached to the upper cylinder 5 has the packaging material 3 attached to its lower surface, and the lower compression plate 7 attached to the lower cylinder 8 has the packaging material 3 attached to the lower surface thereof. A packaging material 6 is attached to the top surface, and the fibers 2 in the box 1 are sandwiched between them. The upper cylinder 5 then descends to compress the fibers 2, as shown in FIG. Upper cylinder 5
When the force exceeds the holding force of the lower cylinder 8, the lower compression plate starts to descend and slips out under the box 1 while keeping the fibers 2 compressed, resulting in the state shown in Figure 4, and the predetermined compression is achieved. Once completed, it is wrapped using the upper and lower packaging materials 3 and 6. Then, as shown in FIG. 5, a plurality of bands 9 are hung using the band hanging grooves 10. After the band is applied, the upper compression plate 4 rises as shown in FIG. 6, and the compressed fibers swell up and down in an attempt to restore the original size due to its repulsive force, but the size does not balance the tension of the band 9. It becomes stable and becomes a package 11 as shown in FIG.

However, the conventional package 11 does not have the ideal packaging condition as shown in FIG. 8, and as shown in FIG. It has drawbacks such as protrusion, poor appearance, and reduced commercial value, and conventionally, it has been necessary to deal with this problem by manual sewing or taping.

[Problems to be solved by ideas]

As a device to deal with this, for example,
In the method described in Publication No. 143683, a projecting body that can protrude outward is inserted into the side opening end (the surface on which the band is applied) of the package, and the opening end is pulled outward to tighten the end surface. Although the band is tensioned to prevent sagging on the end face where the band is not applied, sagging occurs on the side face where the band is applied, and there is also a drawback that the package cannot be used unless it is in the shape of a bag.

That is, since a sheet-like package is folded into a prismatic shape, such a method of pulling outward will cause the folded portion to come off, making it impossible to wrap the package. This bag-like packaging is difficult to feed automatically compared to sheet-like packaging;
Conventionally, supplying was done manually and the work was complicated.

This invention was proposed in view of the above points,
The purpose is to eliminate the slack in part a shown in Figure 7 without manual intervention, to achieve the ideal packaging condition as shown in Figure 8, and to create sheet-like packaging that can be automatically fed. This packaging material pulling device for compression packaging machines can improve work efficiency by being applicable to bodies, meeting the needs for labor saving and complete automation in the packaging process, which have been rapidly increasing in the textile industry in recent years. Our goal is to provide the following.

[Means to solve the problem]

The present invention uses a compression packing machine that wraps a compressed object in a rectangular packaging material and wraps it with a band on the outside. A holding member that holds the needle-like member and is moved in a direction to tighten the packaging material on the mirror surface of the object to be packed after the needle-like member is inserted into the packaging material; and driving means for moving the needle-like member in a direction to insert it into the packaging material, and for moving the needle-like member in a direction to tighten the packaging material on the mirror surface of the object after being inserted into the packaging material. This article focuses on the packaging material pulling device of the compression packing machine.

[Effect]

This invention wraps the package by inserting a needle-like member into the packaging material after banding, moving the needle-like member in the direction of tightening the packaging material on the mirror surface of the packaged item, and then releasing the compression to restore the packaged item. It is possible to eliminate sagging of the material.

That is, in the present invention, a needle-like member is inserted into the side surface on which the band is hung, and the packaging material is pulled along the surface of the packaged item. Both can be packaged tightly.

[Effect of idea]

Therefore, not only the storage capacity of the contents but also the appearance can be improved, the commercial value can be improved, and operations such as sewing and taping after packaging can be made unnecessary.

Furthermore, sheet-like packages can be tension-wrapped, making it easier to automatically feed packages and improving work efficiency. Bag-like packages can also be tension-wrapped, making it easy to change from conventional technology. It is.

〔Example〕

The present invention will now be described with reference to an embodiment shown in Figs.

Components that are the same as those in the prior art are designated by the same reference numerals, and descriptions thereof will be omitted.

In FIG. 9, reference numeral 12 denotes a cart that is provided front and rear opposite to the packaged item 11 and assembled symmetrically with respect to the packaged item 11. ' is used as a guide, and the air cylinder 13 moves between the waiting position A and the packaging press position B.

The guide rails 14, 14' are V-shaped to prevent the cart from falling or falling off.

The rod head of the air cylinder 13 is fastened to a truck 12, and a pulling device C described below is provided on the truck 12.

The pulling device C is installed on a bracket 28 provided on the truck 12, as shown in FIGS. 10 to 12.

A bracket 24 incorporating the pulling device C is smoothly moved by an air cylinder 23 using a guide rail 25 as a guide, and the rod head of this air cylinder is connected to the bracket 24.

The pulling devices C are assembled symmetrically on two sets of carts 12, are always in a backward position, and move forward until they come into contact with the packaged item 11 during the pulling operation.

The guide rail 25 has a V-shape to prevent the pulling device C from falling over or falling off. The two sets of pulling devices are attached to the packaged object 11 so as to be located between the bands 9 .

As described above, the series of carts and pulling devices described above are also installed symmetrically on the rear side of the packaged item 11.

The pulling device C is incorporated into the bracket 24, as shown in FIGS. 13 to 16.

A block 18 is moved via an arm 15 by the operation of an air cylinder 16, and this block 18 has a concave shape so as to sandwich a holder 19 therebetween. Furthermore, this block 18
The structure allows smooth movement from side to side using shafts 21 and 22 as guides.

The arm 15 is designed to swing around a pin 29 incorporated in the bracket 24, and the air cylinder 16 is always in an extended state.

The holder 19 moves on the shaft 21 following the movement of the block 18, and the holder 19 is provided with a needle 20, the tip of which bites into the object to be packaged 11. It is sharpened for ease of use. Further, the reaction force when the needle 20 bites into the packaged item 11 is held by the spring 26, and the abnormal load when the packaged item is restored overcomes this spring force and the holder
9 is rotated to protect the device.

Note that the needle 20 can be adjusted to maintain a constant direction by a set bolt 27 and by a compression plate 4.
The needle 20 is designed to come out of the package when the package 11 is restored.

After banding is completed (see Fig. 5), the cart 12 is moved to the position of the packaged items 11 by the air cylinder 13, and the pulling device C pulls the packaged items 11 between the bands as shown in Fig. 9. It stops at the approach position B.

The air cylinder 23 moves the bracket 24 forward until the needle 20 comes into contact with the package 11 and pierces the package as shown in FIG.
