Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fabric width cutting apparatus, and more particularly to a fabric width cutting apparatus that performs constant length cutting (length cutting) and width cutting simultaneously.
[0002]
[Prior art]
Conventionally, when a fabric roll such as curtain fabric is cut into a predetermined length using a cutting machine, the cloth is removed with a take-off roller while measuring with a length measuring roller using a cutting machine as shown in FIG. Send it out. When the predetermined length is reached, the feeding is stopped, and the fabric is cut by the traveling cutter that travels in the width direction below the take-up roller.
[0003]
As a conventional cutting machine, there is a “fabric constant length cutting machine” proposed by the present applicant and disclosed in JP-A-6-106495. This is because when a long fabric such as a curtain fabric is cut to a predetermined length, a long table used to widen the curtain fabric is not required, the installation area is reduced, and the tension applied to the fabric is reduced. It is to make it constant. In this cutting machine, the fabric roll is rotated by a feed roller to feed the fabric. This fabric is taken up by the take-up roller on the upper front side through the intermediate feed roller at the tip of the upper swing arm. The amount of fabric slack between the take-up roller and the intermediate feed roller and the amount of fabric slack between the intermediate feed roller and the feed roller are controlled within a predetermined range.
[0004]
By the way, when performing curtain sewing, there are cases where the width of the original fabric is inevitably cut to a half width or the like depending on various conditions such as the window size, the original fabric width, and the fold factor. In that case, fixed length cutting (length cutting) is performed in advance, and then the fabric is folded into a half width or a mark is attached, and a person cuts to a predetermined width with scissors or the like.
[0005]
[Problems to be solved by the invention]
However, in the conventional cutting method, since the width cutting is performed after the fixed length cutting (length cutting), extra time is consumed. In particular, when cutting the width of a long curtain place into a half width or the like, a large place and considerable labor are required. Further, since it is manually performed by a person, it is difficult to cut straight, and the dimensions may vary.
[0006]
An object of the present invention is to solve the above-described conventional problems, and to provide an apparatus capable of performing constant length cutting (length cutting) and width cutting at the same time and accurately cutting a fabric.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, width cutting is performed while measuring the length of the cloth by attaching it to a cutting machine having a length-cutting cutter for cutting the cloth roll such as curtain cloth to a predetermined length. A cloth width sizing device for performing a rotary blade provided in parallel to a fabric length direction, a motor for driving the rotary blade, and a driving force of the motor being transmitted to the rotary blade. The transmission means, and the mounting means for attaching the rotary blade, the motor, and the transmission means to the downstream side of the length measuring roller and take-up roller of the cutting machine immediately after the length cutting cutter . . By comprising in this way, the fixed length cutting (length cutting) and width cutting of a fabric can be performed simultaneously.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.
[0009]
(Embodiment)
The embodiment of the present invention is a width slicing device that provides a rotary blade parallel to the length direction of a fabric and performs width slicing of the fabric while measuring the length.
[0010]
FIG. 1 is a perspective view of a cutting machine equipped with a width cutting device according to an embodiment of the present invention. In FIG. 1, a cutting machine 1 is a device that unwinds a fabric roll such as curtain fabric and cuts it to a predetermined length. The width slicing device 2 is a device that cuts a fabric, such as curtain fabric, that has been unwound from a fabric roll into a predetermined width. The take-up roller 3 is a roller for drawing out curtain fabric and the like from the fabric roll. The rotary blade 4 is a blade that cuts curtain fabric or the like in the length direction. The fabric 5 is a fabric such as a curtain fabric. FIG. 2 is a diagram illustrating a state in which the fabric is removed from the cutting machine. FIG. 3 is a perspective view of the width cutting apparatus. In FIG. 3, the mounting bracket 6 is a member that attaches the width cutting device to the rail of the cutting machine.
[0011]
The operation of the width cutting apparatus according to the embodiment of the present invention configured as described above will be described. A width cutting device 2 having a rotary blade 4 parallel to the length direction of the material 5 to be fed is provided below the take-up roller 3 of the cutting machine 1 shown in FIG. When there is no dough, it becomes as shown in FIG. The cutting machine 1 to which the width cutting device 2 is attached is, for example, a “fabric constant length cutting machine” disclosed in JP-A-6-106495. As shown in FIG. 3, the width cutting device 2 is a device that cuts the cloth linearly in the length direction with a rotary blade 4 that is rotated by a motor, and is provided in the cutting machine 1 in the width direction of the cloth with a mounting bracket 6. It is intended to be attached to a desired position of a rail (not shown). The width cutting device 2 can be easily attached to and detached from the cutting machine 1, and can be removed and placed when there is no need for width cutting. Since the width setting device 2 can be attached at an arbitrary position with respect to the cloth width, the width setting size can be set to any desired size. By using a slide mechanism, a turning mechanism, or the like, it can be retreated to a position away from the fabric so that it does not function.
[0012]
In the cutting machine 1, the dough 5 sent out by the take-up roller 3 while measuring the length is cut into a width corresponding to the mounting position by the rotary blade 4 as it is. At this time, since the fabric 5 is in a natural state (a state in which the external tension is extremely low and only its own weight), the fabric 5 can be cut straight and accurately without being stretched. The width cutting device 2 is provided immediately after a length cutting traveling cutter (not shown) that cuts the dough at a predetermined length . Therefore, depending on the interrelationship between the mounting position of the length cutting traveling cutter and the width cutting rotary blade 4, there may be uncut portions at the end of the fabric, but it is a slight length (about 5 cm). While holding the dough by hand, it can be sent down and cut. Further, when cutting into half widths, since the weights of the left and right fabrics are the same, they can be cut as they are due to their own weight.
[0013]
As described above, in the embodiment of the present invention, the width slicing device is configured to provide a rotary blade parallel to the fabric length direction and perform fabric width trimming while measuring the length. Can be cut.
[0014]
【The invention's effect】
As is apparent from the above description, in the present invention, the width of the cloth for performing width cutting while measuring the length of the cloth by attaching the cloth roll such as curtain cloth to a cutting machine that cuts the cloth roll to a predetermined length. A rotary blade provided in parallel to the fabric length direction, a motor for driving the rotary blade, a transmission means for transmitting the driving force of the motor to the rotary blade, and the rotary blade, the motor, and the transmission means. With a mounting means that is attached to the lower side of the length measuring roller and take-off roller of the cutting machine, so that constant length cutting (length cutting) and width cutting can be performed simultaneously, and space and time The effect is that labor can be saved.
