Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is directed to the removal of pilling from sheet-like fabrics, such as blankets and brushed sheets, in which the front or back surfaces of fabrics are covered by free ends of fibers. METHODS AND APPARATUS.

(b) Conventional technology Sheet-like products such as blankets and brushed sheets whose front or back surfaces are covered by free ends of fibers (hereinafter simply referred to as blankets) are susceptible to damage caused by contact friction with the body during use. Pilling pilling occurs, significantly deteriorating the feel, texture, and appearance. Therefore, in the cleaning industry, pilling pills are removed manually using a T-shaped hand-type pilling pill remover. On the other hand, in order to automate this manual work, as shown in Japanese Patent Application Laid-Open No. 159351/1983, the blanket is kept in an expanded state and heated with dry heat to make it almost completely dry and at a high temperature. A pilling removal method and an apparatus have been proposed in which the surface of the hair is lightly rubbed by a hair opening roller that rotates at high speed, and then lightly rubbed by a scraping roller that rotates at high speed.

(c) 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. Pilling pilling occurs noticeably in the vertical center area, and as this central area becomes thinner than other areas over time, more pilling pilling is seen in the thinner area. become.

For this reason, the pilling pill of the blanket is
Even if the blanket is lightly rubbed by a hair opening roller or scraping roller as in the device described in No. 56-159351, the rubbing action of the rollers on the important part where pilling pill occurs will be weaker than on other parts. It is inevitable that
Even if effects such as airflow are added, it is difficult to apply an even rubbing effect to the entire surface of the blanket. Moreover, the device requires a large number of roller groups, which not only increases the equipment cost but also makes the operation and maintenance of the device extremely complicated.

(d) Means for Solving the Problems The present invention solves the various difficulties of the conventional methods and devices described above, and uses simple equipment to remove pilling pill scraping rollers to remove uneven thickness in the width direction of the blanket. Regardless, the present invention provides a method and device for removing pilling that can be applied substantially uniformly in the width direction of the blanket, the basic configuration of which is shown in FIGS. 1 and 2. A suction box provided with a slit 2 extending in the width direction of the blanket 1 on at least one side of the blanket 1 that is moved by moving the blanket 1 in the unfolded state along a table surface capable of supporting the unfolded blanket 1. A scraping roller 4 equipped with a comb needle on the outer periphery is rotated in the suction box 3 with a part of its peripheral surface facing the slit 2, and by the suction action of the suction box 3, The surface of the blanket 1 passing through the suction box area is bulged toward the slit 2, and a scraping roller 4 is applied to the bulged surface 1A to remove pilling pills.

(E) Effect The blanket 1 passing above the suction box 3 receives the suction force of the suction box 3 and gradually expands toward the slit 2, so that the blanket 1 becomes thinner in the center. Even if there is a swollen portion, it will contact the circumferential surface of the scraping roller 4 evenly, and the blanket 1
The scraping roller 4 acts in the entire axial direction of the roller to remove pilling pill.

(f) Embodiments To explain more specifically the drawings schematically showing embodiments of the present invention, 10 in FIG.
1 is a table on which the unfolded blanket 1 is placed, and 11 is an endless chain that is provided on both sides of the table 10 and rotates in the same direction at the same speed. nip bars 12 for holding the front edge of the blanket 1 at intervals slightly larger than the standard length dimension of the blanket 1;
is attached, and the front edge of the blanket 1 is held by the nip bar 12, so that the blanket 1 is moved from one side to the other on the table 10 as the chains 11, 11 rotate.

The table 10 described above has a slit 2 whose upper surface is flush with the table 10 and extends in the width direction of the table 10 on the upper surface side as shown in FIG.
A suction box 3 is provided, and a scraping roller 4 is installed inside the suction box 3. The scraping roller 4 has a comb needle 13 on its outer periphery, and its upper peripheral surface faces along the slit 2, and the comb needle 13
is arranged such that the tip thereof does not protrude from the slit 2, and the direction of the arrow, that is, the direction of rotation of the upper circumference side is opposite to the direction of movement of the blanket 1. The shape of the comb needle 13 applied to the present invention is not particularly limited, but for removing pilling from a blanket, the comb needle 13 has a base extending radially and a tip extending in the direction of rotation, as shown in FIG. A shape that looks like it is bent in the opposite direction is desirable. Further, the above-mentioned suction box 3 is connected to the intake fan 14 on its lower surface side, and since the suction action is performed almost evenly over the entire length of the slit 2,
It is preferable to connect several intake pipes 15 to the lower surface or longitudinal side of the suction box, and to provide each intake pipe with an intake fan 14.

Nip bar 1 for holding the front end of the blanket 1
2, several clip-type gripping tools 13 are arranged in a row, and can be opened and closed manually or automatically by an operator.

FIG. 5 shows a mode 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. 3, a suction box 3' having the same structure as the above embodiment is provided diagonally above the suction box 3, preferably diagonally above the direction in which the blanket 1 moves, with its slit 2 facing downward. It is arranged close to the moving blanket 1.

In this case, the distance between the lower surface of the second suction box 3' and the upper surface of the table 10 must be set to at least a sufficient dimension to allow the above-mentioned nip bar 12 to pass through. When the thickness 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 table surface 16 below the second suction box 3' is configured to be movable up and down in the width direction, so that the nip bar 12 passes below the suction box 3'. For example, the electromagnetic solenoid 17 is actuated by detecting this, and the table surface 16 is raised to bring the top surface of the blanket 1 close to the bottom surface of the suction box 3', so that the end of the blanket 1 is brought close to the bottom surface of the second suction box 3'. 1, the electromagnetic solenoid 17 is deactivated and the table surface 16 is lowered to its original state.

Next, to explain the procedure for removing pilling pill according to the embodiment shown in FIG. When the start switch is turned on, the suction fan 14, the rotation motor (not shown) of the scraping roller 4, and the drive motor (not shown) of the chain 11 are rotated, and the blanket 1 is pulled by the nip bar 12 and moved to the table 10.
move on. When the front end of the blanket 1 reaches the first suction box 3 and is subjected to the suction action by the slit 2, the blanket 1 bulges out slightly on the back side toward the inside of the slit 2, and is curved into the first suction box 3. As shown in FIG. 1, the combing needles 13 of the scraping roller 4 act on the bulging surface 1A, and the pilling removal action on the back surface of the blanket 1 is first started.

Subsequently, when the nip bar 12 passes the lower surface of the second suction box 3', the solenoid 17 is operated to lift the table surface 16 below, bringing the surface of the blanket 1 close to the lower surface of the second suction box 3'. Due to the suction action from the slit 2 of the suction box 3', the blanket 1 is bulged upwards toward the slit 2, contrary to the case of the first suction box 3, thereby removing pilling from the surface side of the blanket 1. is started.

As the blanket 1 moves, the back side and the front side of the blanket 1 are sequentially and alternately bulged toward the first and second suction boxes 3, 3' slits 2, 2, as shown in FIG. Pilling removal is performed simultaneously on both the front and back surfaces by the removal rollers 4, 4. Then, it is detected that the final end of the blanket 1 has passed through the second suction box 3', for example, based on the position of the preceding nip bar 12, and the table surface 1 is
0 is lowered and restored, the device is stopped, the blanket 1 that has been treated to remove pilling is removed, and the untreated blanket 1 is transferred to the nip bar 12 on the introduction side.
Then, start processing the untreated blanket in the same way.

In addition, the moving speed of the blanket, the suction power of the suction box,
It is desirable to change the circumferential speed of the scraping roller arbitrarily depending on the occurrence of pilling on the blanket to be treated, the quality of the blanket, the degree of flexibility, etc. Therefore, a variable speed motor is used as the drive source for each part. It is good if it is suitable.

(G) Effects of the Invention As described above, in the present invention, chains 11 which rotate at the same speed are provided on both sides of the table 10 which is sufficiently larger than the size of the blanket 1, and the blanket 1 is held between the chains and placed on the table surface 10. A nip bar 12 is attached to move the blanket 1, and a nip bar 12 is attached to the moving path of the blanket 1.
A suction box 3 is provided with a rotating scraping roller 4 inside and a slit 2 extending in the width direction of the table 10 on the opposite side of the blanket 1. The surface of the blanket that passes through the suction box area is sequentially bulged toward the slit, and a scraping roller is applied to the bulged surface to remove pilling pill from the blanket. Even if the thickness of the blanket has become thinner in the center due to use, the bulging part will be straight across the width of the blanket, and the scraping roller will act evenly in the width direction of the blanket. However, the pilling pill can be effectively removed over the entire surface of the blanket, and the removed pill can be introduced into the dust collecting section. Moreover, pilling removal is carried out mechanically, there is no pill adhesion or clogging to the scraping roller, no stripping roller is required, which significantly reduces the labor of the operator, and the device is simple and safe. It is also excellent in terms of hygiene, so it is particularly suitable for use in the industry where a large number of blankets are cleaned.
