Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a device for pleating fabric.

[Conventional technology]

Traditionally, the method of adding pleats to fabric is to fold the fabric in order starting from one end. Although there are some mechanized methods for adding pleats to fabric using this method, most of the work is done by hand. It was carried out by

[Problem that the invention seeks to solve]

However, with the mechanized pleating method described above, it is not possible to freely adjust the pleat spacing or change the number of pleats, and furthermore, the fabric is folded in sequentially from one end, which reduces work efficiency. Moreover, there are problems in that the operating conditions of the machine are complicated and it is difficult to put it into practical use.Also, if the above pleating work is done by hand, it is difficult to position the pleat intervals and make the pleat intervals even. The problem was that it was very time consuming.

Therefore, the pleating device of the present invention has been developed in order to solve the problems associated with the conventional pleating work and the device.

[Means for solving problems]

Therefore, the pleating device of this invention
A plurality of holders 1 are arranged in a row so as to hold the holders 1 and reduce the distance between them all or every other one or more, a vertical movement means 12 for vertically moving the holders 1, and the holder 1. A replenishment means 16 for the fabric 2 provided below, and a replenishment means 16 for the fabric 2
It consists of a conveying means 22 for a pasting member 21 for the fabric 2 provided below.

[Effect]

By implementing the above means, the pleating device of the present invention reduces the interval between the holders 1 and moves the holders 1 up and down by the vertical movement means 12 to apply pleats to the fabric 2 and to replenish the fabric 2. The fabric 2 is pulled up from the means 16, and further the fabric 2 is pulled up from the means 12 for vertical movement.
By moving the holders 1 up and down, the pleated fabric 2 can be attached to the attachment member 21 being conveyed by the conveyance means 22.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the pleating device of the present invention will be described below with reference to the drawings.

1 and 2 show a pleating device of the present invention, in which a fabric 2 is held by holders 1 of this pleating device, and by reducing the interval between these holders 1, the fabric is I try to add pleats to 2. The above-mentioned holders 1... are a plurality of holders arranged in a row so that the intervals between them can be reduced all or every other one or more. For example, in the one shown in FIG. 3a, the pleat interval adjuster 3 , the holder 1, the coil spring 4, and the holder 1 are repeatedly attached to the grooved rail 5 in this order, so that the distance between the holders 1... can be reduced every other time,
In addition, in the case shown in FIG. 3b, the bar-shaped rails 5a, 5b are passed through the holders 1, and the mutual spacing between the holders 1 is adjusted by the coil spring 4 and the pleat spacing adjuster 3 (in this example, the stopper). ) so that it can be reduced to every other item.

When the holder 1 shown in FIG. 3a is installed in the pleating device of the present invention, for example, as shown in FIG. 4, the grooved rail 5...
A rectangular frame 6 is formed by slidably connecting both ends of the holders 1 to each other, and by contracting the rectangular frame 6 two-dimensionally, the mutual spacing between the holders 1 is reduced to one dimension two-dimensionally. It is possible to reduce the size at any time. By doing this, pleats can be applied to all four sides of the fabric 2 at once.

Further, each of the holders 1 is provided with an appropriate holding means 7 for holding the fabric 2 and an appropriate detachment means 8 for detaching the fabric 2. In the embodiment, as shown in FIGS. 5a and 5b, the holding means 7... have an adhesive layer on the lower surface of each holding tool 1..., and the detaching means 8... Therefore, the frame body is pushed down by the piston rod 10 descending in the air cylinder 9 and pulled up by the coil spring 11, thereby moving up and down along the lower side of the holder 1.

Next, the pleating device of the present invention includes means 12 for vertically moving the holders 1 . The vertical movement means 12 shown in this embodiment is constructed by connecting a rectangular frame 6 with holders 1 attached to a piston rod 15 of a piston engine 14 suspended from a pedestal 13. It can also be carried out by using means such as a device.

Furthermore, below the holders 1, there is provided means 16 for replenishing the fabric 2. This supply means 16 is
In the structure shown in FIG. 1, the fabric 2 is placed on a work board 17, and the work board 17 is slid horizontally by a slider crank mechanism 18, so that the fabric 2 is held by the holders 1... Sometimes, the work board 17 holder 1... is pulled out from below and the fabric 2 is supplied onto the work board 17. In the case shown in FIG. The structure is such that a plurality of work boards 17 are intermittently installed on a chain conveyor 19 and conveyed in the horizontal direction, and after the fabric 2 is held by the holders 1... Move from below,
The lower part of the holders 1 is an intermittent space 20 in which no work board 17 is installed.

Further, below the fabric 2 replenishing means 16, a conveying means 22 for the fabric 2 pasting member 21 is provided. This conveying means 22 is a belt conveyor on which the pasting members 21 are placed one after another in both the conveying means shown in FIG. 1 and the conveying means 22 shown in FIG. 2
In the case shown in FIG. 2, the fabric 2 loading/unloading means 16 is
It is installed perpendicular to the Note that as the pasting member 21, a cardboard or the like whose surface is pasted with paster (not shown) is used.

The pleating device configured in this manner exhibits an operating state as described below.

First, the piston rod 15 of the piston engine 14
By moving the holder 1 downward, the holder 1 attached to the rectangular frame 6 is lowered, and the holding means 7 of the holder 1 holds the fabric 2 on the work board 17, and the fabric 2 is held on the work board 17. Fold the fabric 2 by reducing the interval between the tools 1... (parts A and B in Fig. 3 are the pleats, and part B is the gap between the pleats), and then move the piston rod 15 upward. As a result, the fabric 2 is pulled up from the work board 17. Alternatively, in the above operating state, the fabric 2 on the work board 17 is held by the holding means 7 of the holder 1, and the fabric 2 is pulled up from the work board 17 by first moving the piston rod 15 upward. Folds may be added to the fabric 2 by reducing the interval between the holders 1. In this case, since the pleats are formed downward, by providing means such as blowing air from below the fabric 2, the pleats can be formed upward.

When pleating the fabric 2, the pleat spacing and number of pleats can be freely adjusted by simply changing the length and position of the pleat spacing adjuster 3.

On the other hand, in the apparatus shown in FIG. 1, after pleating the fabric 2 as described above, the work board 17 is pulled out from below the holder 1 by the slider crank mechanism 18, and the fabric is placed on top of the work board 17. Replenish 2. Moreover, in the apparatus shown in FIG. 2, after pleating the fabric 2 as described above,
Work board 1 installed on chain conveyor 19
7 from below the holder 1...
The lower part of the space is an intermittent space 20 where no work board 17 is installed. Note that the fabric 2 is replenished on the work board 17 from which the fabric 2 has been pulled up.

Next, by moving the piston rod 15 of the piston engine 14 downward, the rectangular frame 6
The holder 1 attached to the... is lowered and the pleated fabric 2 is pressed against the pasting member 21 placed on the conveying means 22, thereby being pasted to this pasting member 21, and the detaching means 8 removes the fabric 2. The pleated fabric 2 is separated from the holder 1.

By repeating the above-mentioned operations, the pleating device of the present invention creates pleated fabric 2.
are successively pasted onto the pasting member 21.

〔Effect of the invention〕

The pleating device of the present invention is configured as described above, and can pleat the entire side of the fabric at once, and the device does not have to operate in a very complicated manner. Since pleats can be added to the material, and the pitch and number of pleats can be freely adjusted as required, it has excellent effects such as greatly improving work efficiency.
