Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for removing pilling from sheet-like products such as blankets and brushed sheets whose front or back surfaces are covered with free ends of fibers; It is related to the device.

(0) Conventional technology Sheet-like products such as blankets and brushed sheets whose front or back surfaces are covered by the free ends of fibers (hereinafter simply referred to as blankets) are prone to pilling due to contact friction with the body during use. This causes a significant deterioration in the feel, texture, and appearance. For this reason, in the cleaning industry, hair balls are removed manually using a Hasidic-type pill remover with a 7-shape shape. On the other hand, in order to automate this manual work, Japanese Patent Publication No. 56-159851
As seen in the issue, while keeping the blanket spread out,
Pillish fuzz is created by heating the blanket with dry heat to make it almost completely dry and at a high temperature, and in that state, the surface of the blanket is lightly rubbed with a high-speed rotating open hair 0-5, and then lightly rubbed with a high-speed rotating scraper O-ra. A removal method and device have been proposed.

01) Problems to be solved by the invention However, in the case of bedding sheets such as blankets, the longitudinal center part usually experiences stronger sliding friction with the body than other parts. A noticeable amount of pilling occurs in the central part of the hair, and as this central part becomes thinner than other parts over time, more pilling is seen in the thinner area. It turns out.

For this reason, the tingling of such blankets is caused by
Even if the blanket is lightly rubbed with a hair opening 0-5 or scraping O-ra like the device described in No. 159351, the rubbing action of the roller on the important part where pimples and hair balls occur is more than on other parts. This cannot be avoided, and even if effects such as airflow are added, it is difficult to apply an even rubbing effect to the entire surface of the blanket. The nine-tooth device requires a large number of roller groups, which not only increases equipment costs, but also significantly complicates the operation and maintenance of the device.

3) Means for Solving the Problems The present invention solves the drawbacks of the conventional methods and devices described above, and uses simple equipment to remove pilling rollers regardless of thickness unevenness in the width direction of the blanket. , provides a method and device for removing pilishif that can be applied substantially uniformly in the width direction of the blanket, and as shown in FIGS. 1 and 2, the basic structure thereof is At least one surface side of the blanket (1) to be moved is equipped with a suction box (
8), a scraping roller is disposed inside the suction box (3), and the scraping roller (4) is rotated with a part of its peripheral surface facing the slit (2), and the suction box The surface of the blanket (1) passing through the suction box area is bulged out toward the slit (2) by the suction action of (3), and the scraping roller (4) is applied to the bulged surface (IA). It is designed to remove pilinchy hair balls.

(E) Effect: The blanket (1) passing above the suction box (8) receives the suction force of the suction box (8) and opens the slit (2).
Therefore, even if the blanket (1) is thinner in the central part, the bulging part contacts the circumferential surface of the scraping roller (4) evenly, and the blanket ( The scraping roller (4) acts on the entire width direction of 1) to remove the pimples and fluff balls.

(F) Embodiments To explain more specifically the drawings schematically showing the embodiments of the present invention, in FIG. 8 α0) is a table on which the unfolded blanket (1) is placed, and αη is the table ( c) An endless chase that is provided on both sides of the blanket and rotates in the same direction at the same speed, with a distance between the endless chases (b) and (b) that is longer than the standard length of the blanket (1). A pilling pill removal method 2) for pinching the front edge of the blanket (1) at large intervals is attached, and the front edge of the blanket (1) is sandwiched by the pilling pill removal method 6). As the chaser αηaη rotates, the table ←0)
The top can be moved from one side to the other.

The above-mentioned table (to) has its top surface set to table (1).
A suction box (3) with a slot (2) extending in the width direction of the table α0) is provided on the upper surface side as shown in FIG. 2 flush with the suction box (3).
) is equipped with a scraping roller (4). The scraping 〇-ra (4) is equipped with a comb needle 01 on the outer periphery, the upper peripheral surface thereof faces along the slit (2), and the tip of the comb needle (to) protrudes from the slit (2). The blanket (1) is arranged so that the direction of the arrow, that is, the direction of rotation of the upper peripheral surface side is opposite to the direction of movement of the blanket (1). The shape of the comb needle 0:1 applied to the present invention is not particularly limited, but for removing pilishifuge from a blanket, the base extends radially and the tip ends as shown in Figure 1. It is desirable to have a shape that is bent in the direction opposite to the direction of rotation. In addition, the above-mentioned suction box (8) is connected to the intake fan on the lower surface side, and in order to perform the suction action almost evenly over the entire length of the slit (2), the lower surface or longitudinal side of the suction box It is preferable that several intake pipes (to) be connected to the intake pipes, and each intake pipe should be provided with an intake fan (L4).

In pilling pill removal method 2) for holding the front end of the blanket (1), several clip-type holding tools U are installed in rows so that they can be opened and closed manually or automatically by a worker. It has become.

FIG. 5 shows an embodiment in which both sides of the blanket (1) are treated simultaneously by the method of the present invention. That is, in the apparatus shown in FIG. 8, a suction box (3) having the same structure as that of the above embodiment is inserted diagonally above the suction box (3), preferably diagonally above the advancing direction of the blanket (1), through its slit ( 2)
The blanket (1) is placed close to the moving blanket (1) with the lower surface thereof.

In this case, this second suction box (8)
The distance between the lower surface and the upper surface of the chewing pill α0) must be set to at least a sufficient dimension to allow passage of the pilling pill removal method 2) described above, so the appearance of the pilling pill removal method 6) When the thickness of the suction box (3) is large, it becomes difficult to bring the slit (2) of the suction box (3) close to the blanket (1). In order to deal with this difficulty, in this embodiment, the lower table surface (to) of the second suction box (8) is configured to be movable up and down across its width, and the lower table surface (to) of the second suction box (3) Pilling pill removal method 6)
Detects that the object has passed and operates, for example, an electromagnetic solenoid ←η to raise the table surface (to) and remove the blanket (1).
Place the top surface close to the bottom surface in front of the suction box, and place a blanket (1
) passes through the second suction box (K), the electromagnetic solenoid αη is deactivated to lower the table surface to its original position.

Next, to explain the procedure for removing pill jig pill according to the embodiment shown in FIG.
When the start end of the suction fan α→, the rotation of the scraping roller (4) (not shown) and the drive upper part of the chaser (b) are (1) is rotated and the blanket (1) moves on the table (2) while being pulled by the pilling pill removal method (2). The front end of the blanket (1) is connected to the first suction box (
8) When the blanket (1) reaches the top and is subjected to the suction action by the slit (2), the blanket (1) will close to the slit (2) on its back side.
2) It is slightly bulged inward and curved, and a scraping roller (4) is attached to the bulged surface (IA) as shown in Figure 1.
The comb needle 0 of the comb needle 0 starts to remove the pilisif from the back side of the blanket (1).

Next, when the pilling pill removal method 6) passes the bottom surface of the second suction box (8), the solenoid αη operates to lift the table surface below it and remove the blanket (1).
The surface of the blanket (1) is brought close to the bottom surface of the suction box (3), and due to the suction action from the slit (2) of the suction box (3), contrary to the case of the first suction box (3), the blanket (1
) is bulged upward toward the slit (2), and the blanket (
The removal action of 1) on the surface side starts.

Thus, as the blanket (1) moves, the back side and front side of the blanket (1) become the first and second
suction box (8) (8) slit (2) (2)
Both scraping rollers (4) (4) are bulged out alternately on the side.
This allows the removal action to be performed on both the front and back surfaces at the same time.

And the final end of the blanket (1) is the second suction box (8)
For example, it is detected by the position of the preceding nip bar 02, the table surface (c) is lowered and restored, the device is stopped, the blanket (1) that has been treated to remove Pillijig fluff is removed, and the introduction side The untreated blanket (1) is held in the pilling pill removal method 2), and treatment of the untreated blanket is started in the same manner.

Note that it is desirable to arbitrarily change the moving speed of the blanket, the suction force of the suction box, the circumferential speed of the scraping roller, etc. depending on the occurrence of pilling on the blanket to be treated, the quality of the blanket, the degree of flexibility, etc. It is preferable to use a variable speed top/bottom drive source for each part.

(g) Effects of the invention As described above, the present invention provides chases (b) that rotate at the same speed on both sides of the table α0) which is sufficiently larger than the size of the blanket (1), and the blanket (1) is placed between the chases. Chive bar (6) for holding and moving on the table surface αO)
A suction box equipped with rotating scraping rollers (4) on both sides of the table (1) and a slit (2) extending in the width direction of the table (on the opposite side of the blanket (1)) (8), the surface of the blanket passing through the suction box area is sequentially bulged out toward the slit by the suction action of the suction box, and a scraping roller is applied to the bulged surface. Because it removes fluff from the blanket, even if the thickness of the blanket has become thinner in the center due to long-term use, the bulging surface will be straight across the width in the bulging part. As a result, the scraping roller acts evenly in the width direction of the blanket, effectively removing the pilling over the entire surface of the blanket, and guiding the removed pill to the dust collecting section. In addition, the pill removal is carried out mechanically, there is no adhesion or clogging of pill to the scraping roller, and there is no need for a scraping roller, which significantly reduces the labor of the operator, and the device is simple and safe. Since it is also excellent in terms of hygiene, it is particularly suitable for industrial use where a large number of blankets are cleaned.
