DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting and laminating dough at one or more required positions on a dough laminating table, and more particularly to an apparatus for cutting and laminating dough in a short time and automatically. Related to a device that allows to do so.

[0002]

2. Description of the Related Art Clothes for clothes and Japanese clothes are supplied as a very long material roll, and after cutting the material into a predetermined length, it is further cut into various types of predetermined parts, and the sewing process is performed. After that, it is marketed as the desired clothes. For example, in the case of clothing for suits, the cloth worn by one suit has a length of less than 2 meters and a width of about 1 meter. Fabrics of this size are light in weight but large in area but difficult to handle, and various improved methods have been proposed for automatically or semi-automating the work of laminating fabric cut from a roll-shaped raw material (for example, JP-A-57-132995, JP-A-59-59399, etc.).

[0003] As one of the methods, a method of extruding a dough from a raw material onto a conveyer, extruding the conveyer onto a dough lamination table, transferring the tip of the dough to the dough lamination table, pulling back the conveyer, and then cutting the dough. Is known (Japanese Patent Publication No. 52-2037). This method is suitable as a means for cutting a plain blank into a predetermined length of fabric and stacking the same. However, in recent years, the sense of fashion has been refined, so that fabrics having patterns, that is, multi-colored fabrics, are often used as fabrics rather than plain fabrics, and thus raw fabrics are also produced as repetitive patterns having predetermined color patterns. . Garment designers design to maximize the decorative effect, especially by locating the main color pattern at predetermined locations on the finished garment. Further, it is necessary to match the color or pattern at the boundary surface of each part.

However, if the above-described method is employed for cutting a raw material having a repetitive pattern, the same pattern can be set at an arbitrary position because the method determines the position of the cloth and then cuts the cloth. Therefore, the position of the pattern of the cut dough to be laminated is not constant, and if the cutting and sewing process proceeds as it is, the pattern will be located at a place other than the intended place and the clothing of the design contrary to the intention of the designer will be manufactured. And the boundary of each part becomes unnatural. In these known laminating methods, the cut dough is laminated at a fixed position on a dough lamination table. However, depending on the type and use of the dough, it may be laminated as a separate dough laminate at multiple locations on the dough lamination table,
Even in the case of a single dough laminate, it may be preferable to change the lamination position.

[0005] In each of the above-mentioned laminating methods, no consideration has been given to changing the cloth laminating position, and thus such a request has not been met. The present inventor has proposed a dough laminating apparatus to meet 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 fabric 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 located below the left end of the dough lamination table b, and
The roller brake a is connected to a belt return lever e by a conveyor belt d bent by two pairs of rollers c. A blade receiver f, a cloth holder g above the blade holder f, and a cutter h slightly above and to the left of the cloth holder g are located beside the belt folding lever e. It is designed to move in the horizontal direction. In addition, i is a guide plate continuously provided downward 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 through the hole of the fabric lamination table b.

In this state, the cloth m from the raw material is sequentially brought into contact with the belt folding lever e, the blade receiver f and the guide plate i and is pressed by the cloth presser g. Then roller brake a
Is turned on, and the belt brake j is turned off. In this state, the belt return lever e is advanced leftward. 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 fabric stacking table b without causing slip, The dough m thereover similarly reaches the upper space near the left end of the dough stacking table b (FIG. 1B).

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 loosing the fabric presser g (FIG. 1C).
As a result, the belt folding lever e moves to the right,
Since the movement of the endless belt d is restrained by the belt brake j, the belt d in contact with the fabric m
The surface does not move, so that the fabric m descends onto the fabric lamination table b and engages with the needle k to be laminated as shown in FIG. 1C. Next, when the cloth reaches a predetermined length, the cutter h is operated to cut the cloth m (FIG. 1D), and the cut cloth m ′ is stacked on the cloth stacking table b.

In this state, the roller brake a is further moved to the left and the belt folding lever e is moved to the right, and a similar cutting operation is performed. "Can be laminated.
From the state of D, the roller brake a is turned on, the belt brake j is turned off, and the belt return lever e is moved to the position shown in FIG.
When the state is returned to the state of B and this is repeated, only the first laminated fabric m 'can be laminated. As described above, according to the present invention whose outline is illustrated in FIG. 1, since the cutter h is movable, an arbitrary number of laminated doughs can be laminated at an arbitrary position of the dough lamination table b.

In this device, the belt d moves together with the roller brake a and the belt return lever e without changing the relative positions thereof, with the belt brake j turned off. With the belt brake j turned on, the other surface of the belt d (the inside of FIG. 1C) is held while the position of the surface of the belt d held on the side of the belt brake j (the outside of FIG. 1C) is held. Moving,
Only the two types of movements 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 fabric lamination table b in FIG. 1B.

[0010] For this reason and the like, in order to cut the fabric and shorten the operation time of the laminated layer, these movements alone are not enough. For example, when the roller brake a is turned off, the belt d It may be necessary to move endlessly in one direction between a and the belt return lever e. In other words, in the cutting and laminating operation of FIG. 1, the fabric m ′ cut by the cutter g in the step of FIG. 1B (requiring about 40 seconds) is further laminated after cutting (about 30 seconds). It takes about 70 seconds 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]

SUMMARY OF THE INVENTION It is an object of the present invention to increase the kinds of belt movements of the prior art and to smoothly perform operations such as cutting and laminating of fabrics, and in particular, it is possible to shorten the operation time and achieve the automation associated therewith. To provide a dough cutting and laminating apparatus.

SUMMARY OF THE INVENTION The present invention comprises a dough stacking platform, an endless conveyor belt for transferring dough through a space including the dough stacking platform, and a cutting cutter for cutting the dough. A fabric cutting and laminating apparatus, wherein the conveyor belt is transferred using a conveyor moving motor for moving the conveyor belt and a conveyor rotating motor for rotating the conveyor belt. Alternatively, a braking means for holding the conveyor belt may be separately provided, or the conveyor rotation motor may have its function. It is desirable that the position of the cutter is variable.

Hereinafter, the present invention will be described in detail. In the present invention, the endless conveyor belt is caused to move including the following two kinds of movements by using two kinds of motors, a conveyor moving motor and a conveyor rotating motor. Moving the rollers and the entire conveyor belt 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 (hereinafter, this movement is referred to as rotation). It is desirable that the conveyor movement motor and the conveyor rotation motor be separate motors, but it is also possible to combine a single motor and a clutch so that a single motor can substantially perform both functions of the conveyor movement motor and the conveyor movement motor. It is possible.

Next, the operating principle of the cloth 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 laminating are performed at the same time to shorten the operation time and easily cope with automation. FIG. 2A shows a conveyor moving motor and a conveyor rotating motor, which are two types of motors, and a connecting belt for connecting a pair of rollers. These members are the same in FIGS. 2B, 2C, and 2D. , But are omitted in FIG. 2B and later for simplicity. In the cutting and laminating operation shown in FIG. 2, first, as shown in FIG.
Is pulled out from the raw material to a predetermined position below the cutter 2 and cut into a predetermined pattern by the cutter 2 (movable back and forth, left and right) (at this time, the upper roller 3 and the lower roller 4 are cut).
The endless conveyor belt 6 stretched between the four conveyor rollers 5a, 5b, 5c, and 5d is arranged such that the upper end roller 3 is positioned near the left end of the dough stacking table 7).

The upper sliding portion 9 on which the guide plate 8 and the upper roller 3 are fixed on the side surface is connected to the lower roller by a connecting belt 11 stretched over a pair of connecting belt rollers 10a and 10b. 4 is connected to a fixed lower slide portion, and a conveyor moving motor 12 is connected to the lower connecting belt roller 10b so as to be able to be turned on and off. A conveyor rotating motor 14 is connected via a clutch 13 to the lower right conveyor roller 5d of the four conveyor rollers so as to be able to be turned on and off. The conveyor rotation motor may be connected to another roller 5a or the lower roller 4. When the conveyor rotation motor 14 is turned on and the clutch 13 is turned on, the conveyor belt 6 moves so as 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 a brake to the conveyor belt 6 via the clutch 13 so that a braking (braking) function is exhibited. When the clutch is off, the conveyor rotating motor 14 does not work on the conveyor belt 6. Instead of the illustrated conveyor moving motor and conveyor rotating motor conveyor, for example, a single motor is installed below the fabric lamination table 7, and the motor is connected to the rollers 5d and 10b by belts, and a clutch is used together. Thus, the rotation of the motor can be transmitted to the roller 5d and / or the roller 10b only when necessary.

In order to transport the cut fabric 1a in this state forward (to the left in FIG. 2), a conventional method of moving a conveyor belt is attempted, but in the state of FIG. The cloth 1
a cannot be transferred forward. In the present invention, the conveyor rotation motor 14 and the clutch 13 are turned on after the cutting immediately after FIG. 2A is 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) moves to the upper roller 3 side, and the lower surface moves to the lower roller 4 side. Then, the entire conveyor belt 6 rotates in the direction shown by the arrow in FIG. 2B, and shifts to the state shown in FIG. 2C. At the time of transferring the cut cloth 1a, a brake is applied to the cloth 1 on the material side by an appropriate method so that the cloth 1 before cutting does not move.

From this state, when the conveyor 13 is turned on while the clutch 13 is turned on and the conveyor rotation motor 14 is turned off to apply a brake to the upper surface of the conveyor belt 6, the upper slide portion 9 is turned on. FIG.
Moving rightward from the position C, the cut fabric 1a on the conveyor belt 6 is guided by the guide plate 8 and is laminated on the fabric lamination table 7. At this time, the cutter 2 is located above the cloth 1 before cutting, so that the cutting operation of the next cloth to be cut by the cutter 2 can be performed in parallel with the laminating operation, so that the operation time is reduced. You. By repeating the operations in FIGS. 2A to 2D, the cut dough 1 a is stacked on the dough stacking table 7.

In the description of FIG. 2, the rotation of the conveyor belt and the braking thereof are performed by the combination of the conveyor rotation motor and the clutch. However, the present invention is not limited to this. The motor may rotate only the conveyor belt, and may use another braking mechanism to brake the conveyor belt. It is desirable that the cutter in the present invention shifts to the front, rear, left and right so that the position thereof can be changed, so that it can shift not only in the width direction of the belt but also in the running direction to cut the cloth at an arbitrary position. Making it possible. In the present invention, in addition to the movable cutter, a dough laminating mechanism for stacking dough cut by the cutter and an original fabric of the dough to be cut are transferred to a cutting position, and the dough cut by the cutter is stacked with the dough. It includes an endless conveyor belt to be transferred to a platform.
