[0001]
[Industrial application fields]
The present invention relates to an apparatus for cutting a fabric and stacking it at one or more required locations on a fabric stacking table, and in particular, an apparatus that can automatically and quickly cut and stack the fabric. About.
[0002]
[Prior art]
Clothes for clothes and Japanese clothes are supplied as very long rolls of raw material. After cutting the raw material into a predetermined length, it is further cut into various types of parts and processed into desired parts through a sewing process. It is marketed as.
For example, in the case of suit clothing, the fabric worn by suit 1 is less than 2 meters long and reaches about 1 meter wide. Various improvements have been proposed for the automatic or semi-automated operation of laminating fabrics cut from a roll-shaped raw fabric because the fabric of this size is light in weight but large in area and difficult to handle (for example, specially JP-A-57-132995, JP-A-59-59399, etc.).
[0003]
One method is to push the conveyor onto the fabric stacking table while feeding the fabric from the original fabric onto the conveyor, move the tip of the fabric to the fabric stacking table, pull the conveyor back, and then cut the fabric. (No. 52-2037). This method is suitable as a means for cutting a plain raw fabric into a predetermined length of fabric and laminating it. However, since the fashion sense has been refined in recent years, it is often used as a fabric that has a pattern rather than a plain fabric, that is, a multicolored fabric, and the original fabric is also produced as a repeated pattern having a predetermined color pattern. . In particular, the clothing designer designs the main color pattern at a predetermined position of the completed clothing so that the maximum decoration effect is produced. Furthermore, it is necessary to match the color or pattern at the boundary surface of each part.
[0004]
However, when the above-described method is adopted for cutting a raw material having a repetitive pattern, the same pattern cannot be set at an arbitrary position because the method cuts the cloth after determining the position of the cloth. The position of the pattern of the cut fabric to be laminated is not constant, and if the cutting and sewing processes are carried out as they are, clothes with a design contrary to the designer's intention will be manufactured at positions other than the pattern intended and each The boundary of parts becomes unnatural.
In these known laminating methods, the cut fabric is laminated at a fixed position on the fabric laminating table. However, depending on the type and use of the fabric, it may be preferable to stack the layers as separate fabric laminates at a plurality of locations on the fabric stacking table or to change the stacking position even in the case of a single fabric laminate.
[0005]
In each of the above laminating methods, no consideration has been given to changing the dough laminating position, so such a request could not be met. The present inventor has proposed a fabric laminating apparatus for meeting this demand (Japanese Patent Laid-Open No. 8-113868). This dough laminating apparatus will be described with reference to FIG.
FIG. 1 is a process diagram showing a conventional dough cutting and laminating procedure using an endless belt-like sheet as a conveyor belt.
As shown in FIG. 1A, at the start of the laminating operation, the roller brake a is positioned below the left end of the dough stacking table b, and the roller brake a is belted by a conveyor belt d folded by two pairs of rollers c. It is connected to the folding lever e. Next to the belt folding lever e is a blade receiver f, a cloth presser g above the blade receiver f, and a cutter h slightly above the left of the cloth presser g. At the same time, it moves horizontally. Note that i is a guide plate continuously provided on the left side of the blade receiver f, j is a belt brake for suppressing the movement of the belt d, and k is a needle penetrating the hole of the fabric stacking base b.
[0006]
In this state, the fabric m from the original fabric is sequentially brought into contact with the belt folding lever e, the blade receiver f and the guide plate i and pressed by the fabric presser g. Next, the roller brake a is turned on, the belt brake j is turned off, and the belt folding lever e is advanced in the left direction in this state. Since the movement of the belt d is suppressed by the roller brake a, the belt d moves to the left as a whole, and the belt folding lever e reaches the upper space near the left end of the dough stacking base b without causing slipping, The fabric m above it similarly reaches the upper space near the left end of the fabric stacking table b (FIG. 1B).
[0007]
Next, the roller brake a is turned off, the belt brake j is turned on, and the roller brake a is moved to the left while loosening the cloth presser g (FIG. 1C). As a result, the belt folding lever e moves to the right. However, since the movement of the endless belt-like belt d is suppressed by the belt brake j, the belt d surface in contact with the fabric m does not move. As shown in FIG. 1C, the fabric m descends onto the fabric stacking table b and is stacked by engaging with the needle k.
Next, when the predetermined length is reached, the cutter h is operated to cut the dough m (FIG. 1D), and the cut dough m ′ is stacked on the dough stacking table b.
[0008]
From this state, when the roller brake a is further moved to the left and the belt folding lever e is moved to the right and the cutting operation is performed in the same manner, another laminated fabric m ″ is laminated on the right side of the laminated fabric m ′. can do.
From the state of FIG. 1D, the roller brake a is turned on, the belt brake j is turned off, the belt folding lever e is returned to the state of FIG. 1B, and when this is repeated, only the first laminated fabric m 'is laminated. be able to.
Thus, according to the present invention whose procedure is illustrated in FIG. 1, since the cutter h is movable, an arbitrary number of laminated fabrics can be stacked at arbitrary locations on the fabric stacking table b.
[0009]
In this device, the belt d is moved together with both in accordance with the movement of the belt d without changing the relative position between the roller brake a and the belt folding lever e, with the belt brake j turned off. (2) With the belt brake j turned on, the other surface of the belt d (shown in FIG. 1C) is maintained while maintaining the position of the belt d surface (outside of FIG. 1C) held by the belt brake j. Only the two types of movements (inside) move are performed. For example, the cutting position by the cutter h in FIG. 1 is limited to the vicinity of the left end of the dough stacking table b in FIG. 1B.
[0010]
For this reason, in order to shorten the time for cutting the fabric and the operation of the laminated layer, these movements alone are not sufficient. For example, the belt d is connected to the roller brake a and the belt with the roller brake a turned off. It may be necessary to move endlessly in one direction between the folding levers e. That is, in the cutting and laminating operation of FIG. 1, the fabric m ′ cut by the cutter g in the process of FIG. 1B (which takes about 40 seconds) is laminated after cutting (about 30 seconds) after further cutting. About 70 seconds are required for one cutting and laminating operation. If this cutting and laminating operation can be performed simultaneously, the operation time can be reduced to about 40 seconds.
[0011]
OBJECT OF THE INVENTION
It is an object of the present invention to increase the types of belt movement of this prior art, to perform operations such as cutting and laminating of the fabric more smoothly, and in particular to reduce the operation time and achieve the automation associated therewith It is to provide a cutting and laminating apparatus.
[0012]

It is desirable that the position of the cutter be variable.
[0013]
The present invention will be described in detail below.
In the present invention, two types of motors, a conveyor movement motor and a conveyor rotation motor, are used to cause the endless conveyor belt to move including the following two types of movement. (1) The roller and the entire conveyor belt are moved without changing the relative positional relationship between the pair of rollers at both ends of the conveyor belt and the conveyor belt (hereinafter, this movement is referred to as movement). The conveyor belt is transferred endlessly in the same direction between the pair of rollers without moving the position of the pair of rollers (this movement is hereinafter referred to as rotation). Although it is desirable that the conveyor movement motor and the conveyor rotation motor be separate motors, a single motor and a clutch can be combined to enable both the conveyor movement motor and the conveyor movement motor to function effectively. Is possible.
[0014]
Next, the operating principle of the dough cutting and laminating apparatus of the present invention will be described with reference to FIG. 2, but these descriptions do not limit the present invention. FIG. 2 illustrates, among the effects of the apparatus of the present invention, cutting and stacking at the same time to reduce the work time and easily cope with automation. FIG. 2A shows two types of motors, a conveyor moving motor and a conveyor rotating motor, and a connecting belt that connects a pair of rollers. These members are the same in FIGS. 2B, 2C, and 2D. Although not shown in FIG. 2B, the description is omitted.
In the cutting and laminating operation of FIG. 2, first, as shown in FIG. 2A, the fabric 1 is drawn from the original fabric to a predetermined position below the cutter 2, and is cut into a predetermined pattern by this cutter 2 (movable in the front, rear, left, and right) When the endless conveyor belt 6 stretched between the upper end roller 3 and the lower end roller 4 via the four conveyor rollers 5a, 5b, 5c, 5d, the upper end roller 3 is positioned near the left end of the dough stack 7 Is taken care of).
[0015]
The upper slide portion 9 having the guide plate 8 and the upper end roller 3 fixed on the side surface is fixed to the lower roller 4 on the side surface via a connection belt 11 stretched between a pair of connection belt rollers 10a and 10b. A conveyor moving motor 12 is connected to a lower connecting belt roller 10b which is connected to the lower slide portion provided so as to be turned on and off. A conveyor rotation motor 14 is connected to the conveyor roller 5d at the lower right of the above four conveyor rollers via a clutch 13 so as to be turned on and off. The conveyor rotation motor may be connected to another roller 5a or the lower end roller 4. When the conveyor rotation motor 14 is turned on and the clutch 13 is turned on, the conveyor belt 6 moves to rotate in one direction. When the conveyor rotation motor 14 is turned off and the clutch 13 is turned on, the motor 14 applies braking to the conveyor belt 6 via the clutch 13, and a braking (braking) function is exhibited. When the clutch is turned off, the conveyor rotation motor 14 does not work on the conveyor belt 6. Instead of the conveyor moving motor and the conveyor rotating motor bear shown in the figure, for example, a single motor is installed below the dough stacking table 7, the motor is connected to the roller 5d and the roller 10b by a belt, and a clutch is used in combination. Thus, the rotation of the motor can be transmitted to the roller 5d and / or the roller 10b only when necessary.
[0016]
Even if an attempt is made to move the conveyor belt as in the prior art in order to transfer the fabric 1a cut in this state forward (leftward in FIG. 2), the upper end roller 3 is positioned near the left end in the state of FIG. 2A. Therefore, the cloth 1a cannot be transferred forward.
In the present invention, the conveyor rotation motor 14 and the clutch 13 are turned on with the cutting immediately after FIG. 2A completed. As a result, the rotational force of the motor 14 is transmitted to the conveyor belt 6, and the upper surface of the conveyor belt 6 (the surface in contact with the fabric 1) is moved to the upper roller 3 side and the lower surface is moved to the lower roller 4 side. Then, the entire conveyor belt 6 rotates in the direction indicated by the arrow in FIG. 2B, and shifts to the state shown in FIG. 2C. When the cut fabric 1a is transferred, the fabric 1 on the original fabric side is braked by an appropriate method so that the fabric 1 before cutting does not move.
[0017]
From this state, when the clutch 13 is turned on and the conveyor rotation motor 14 is turned off and the upper surface of the conveyor belt 6 is braked and the conveyor moving motor 12 is turned on, the upper slide portion 9 is moved as shown in FIG. 2C. Shifting from the position to the right, the cut fabric 1 a on the conveyor belt 6 is guided to the guide plate 8 and stacked on the fabric stacking table 7.
At this time, the cutter 2 is positioned above the material 1 before cutting, and therefore the cutting operation of the next material to be cut by the cutter 2 can be performed in parallel with the laminating operation, so that the operation time is shortened. The By repeating the operations of FIGS. 2A to 2D, the cut fabric 1 a is stacked on the fabric stacking table 7.
[0018]
In the description of FIG. 2, the conveyor belt is rotated and braked by a combination of the conveyor rotation motor and the clutch. However, the present invention is not limited to this, and the conveyor rotation motor is a conveyor. Only the belt may be rotated, and the braking of the conveyor belt may be performed using another braking mechanism. A motor that rotates and brakes the conveyor belt is referred to as a brake type conveyor rotation motor, and a motor that only rotates the conveyor belt is referred to as a non-brake type conveyor rotation motor.
It is desirable that the cutter in the present invention shifts to the front, rear, left and right so that its position can be changed, so that it shifts not only in the width direction of the belt but also in the running direction, and cuts the dough at any location. It is possible. In the present invention, in addition to the movable cutter, a fabric laminating mechanism for laminating fabrics cut by the cutter and a raw fabric of the fabric to be cut are transferred to a cutting position and the fabric cut by the cutter is used for the fabric lamination. It includes an endless conveyor belt that is transferred to the platform. The length of the fabric stacking base is longer than the length of the fabric to be stacked, preferably at least twice the length of the fabric, and there are a plurality of fabric stacks in the length direction, or even in the case of a single fabric stack A plurality of stacking positions can be formed, and the stacking can be performed at any of the positions.
