DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fabric pattern matching device, and more particularly to a fabric pattern matching device which is useful in a case where a pattern applied to a fabric is continuous at least in a horizontal direction, for example, a horizontal stripe pattern or a lattice pattern. The present invention relates to an automatic fabric pattern matching device that performs functions.

[0002]

2. Description of the Related Art In recent years, fabrics made of various materials have been marketed as cloth-like fabrics such as clothing fabrics and kimono fabrics. For example, a knitted fabric of a vertical knitting is knitted into a tube shape. It is customary to dye and sort the garnish, cut it out, and then wind it round on a rod-shaped core to finish it. In the case of cutting the raw material rolled in such a manner as described above, the raw material is first pulled out from the raw material, cut into a predetermined size, and the cut material is laminated on a multilayer. Thereafter, cutting into a desired shape is performed using a cutting machine or the like. In this case, when the dough is laminated in multiple layers, it is necessary to perform the dough pattern matching for each layer. In particular, when the dough pattern is a striped pattern or a lattice pattern, the pattern matching is performed accurately. Without
The skewing or bending of the pattern occurs in the cut product, or
Variations occur for each product.

Conventionally, in performing such a pattern matching of a cloth, an operator carefully plies the cloth one by one so that the pattern of the cloth does not bend and the pattern of the cloth is completely matched in each layer. It is customary to match patterns by hand.

[0004]

However, the cloth with the striped pattern or the lattice pattern as described above already has some skew or bend at the time when it is pulled out from the raw material. Because it appears as a habit of the dough, when performing pattern matching by stacking dough in multiple layers, at the same time as many workers overlap the dough one by one, while checking the pattern position one by one Work needs to be done,
As a result, unnecessary work and labor are required, the work becomes complicated and troublesome, and the work efficiency and productivity are necessarily deteriorated. In addition, at present, the pattern matching of the cloth is performed on the upper surface of the worktable, that is, on a horizontal surface, and when the cloth expanded horizontally is overlapped, the cloth always contracts or expands. Therefore, the difficulty of the above-mentioned pattern matching work by hand is remarkable.

[0005] In this type of work, there are a plurality of steps such as unwinding of a rolled raw material, pattern matching of the unrolled fabric, and cutting of the patterned fabric. If a large space is consumed for each process, a very large work space is required as a whole, and there is a problem that a large economical burden is required in terms of a space factor such as securing a site and increasing the size of a building.

The present invention has been made in view of the above-mentioned circumstances, and enables automation of a pattern matching operation of a cloth which has been difficult in the past due to various characteristics of a knitted cloth and the like, thereby improving productivity. It is an object of the present invention to provide an automatic cloth pattern matching apparatus which can be improved, and at the same time, can reduce the size of the apparatus as a whole and achieve an economic effect by saving installation space.

Then, the same operation as described above is repeated until the number of cut fabrics MB reaches a predetermined number (steps S7 and S8).

A predetermined number of cut doughs MB are supplied to the dough receiving needle 1.
The process of taking out the vertically suspended state from the state of being superposed in two layers on the cutting table 104 and changing the state to the horizontal state of superposition is shown in FIGS. This will be described with reference to the flowchart shown. First, after fixing the position of the cradle 14 via the cradle lock cylinder 95,

When the bearing 100 moves rearward while rolling along the linear guide groove 102, and reaches the terminal end thereof, the bearing 100 moves to the arcuate cradle turning guide groove 103. As shown in FIG. 26, the cradle 14 in the vertical posture is naturally rotated by 90 °, and is changed to the take-out posture in which the cut fabrics MB are superimposed on a horizontal plane (step T1).

In this state, the cloth receiving needle 1 is moved by the contraction of the air cylinder 13 for moving the receiving needle back and forth.
2 from the laminated cut fabric MB (step T

Claims (1)

(57) [Claims] An automatic dough solution reaction apparatus 1. A by Kaihan original fabric spread over a predetermined size, downward from the rear upper position of the apparatus frame dough which is spread is Kaihan This automatic dough solution reaction apparatus A dough feeding mechanism for feeding the dough in a hanging manner, an optical reading means disposed opposite to the surface of the hanging portion of the dough fed in a hanging manner to read a continuous pattern in the width direction of the dough, On the back side of the part , spaced apart in the width direction
Pattern matching needles arranged at the location and these multiple pattern matching needles
Pierce the dough individually and remove from the dough
It consists of a needle back and forth moving means that moves backward
And a plurality of pattern matching units that can be individually raised and lowered in the vertical direction, and these multiple pattern matching units are placed and held in a separable manner.
Unit lifting plate, and this unit lifting plate
A pattern matching unit that can be driven up and down
G based on the read signal by the optical reading means,
At multiple locations where multiple pattern matching units are installed
The vertical position of the continuous pattern in the horizontal direction of the fabric
Above, corresponding to the calculated upper and lower positions
For each of the pattern alignment units,
A control hand that instructs the timing of moving the pattern matching needle forward
A step and a cloth cutting device disposed below the optical reading means so as to be movable in the front-rear direction of the apparatus frame, and for cutting the cloth that has been pattern-matched by the pattern-matching unit along its width. Bei example a plurality that are raised collectively by the unit elevating plate
Is read by the optical reading means.
While receiving the completion signal
Each pattern at the timing indicated by the control means.
The needle back and forth moving means of the
To move the corresponding pattern matching needles forward
Pierce the fabric with each pattern matching needle
Of separating each pattern Align unit from the unit elevating plate at location
To stop the descent, and
Each pattern matching unit with its own weight
Therefore, it is necessary to move the unit
And the continuous pattern in the width direction of the fabric should be horizontal and straight.
Control the vertical position of multiple locations in the fabric width direction
The fabric after pattern matching in the width direction.
Automatic fabric patterning configured to cut along
A Align device, the automatic cloth solution reaction apparatus, the dough feeding mechanism, arranged optical reading means, pattern match unit and unit vertical moving device housing for the unit box and the dough cutting apparatus in a predetermined positional relationship respectively An automatic dough pattern matching device, wherein the left and right device frames are integrally connected and supported.
