FIG. 1 is a schematic plan view showing the entire structure of the automatic futon sewing apparatus according to the present invention, and FIG. 2 is a schematic front view showing the entire structure of the automatic futon sewing apparatus according to the present invention. An automatic futon sewing apparatus according to the present invention comprises a cloth feeding means (1) for feeding one long futon cloth (U) into the apparatus by a fixed length.
And a horizontal tape bonding means (2) for bonding the strip-shaped tape (T1) at regular intervals to the feeding direction of the fed one cloth (U) or in another direction, and the horizontal tape is bonded. A plurality of vertical tape supply means (3) for supplying a belt-shaped tape (T2) to the surface of one fabric in the transport direction of the one fabric;
Another dough supply means (4) for supplying another dough (O) on the surface of one dough in the conveying direction of one dough so as to overlap on the vertical tape; The sewing machine includes a plurality of sewing machines (5) for sewing one fabric to each other, and a cutting device (6) for cutting the fabric sewn by the sewing machine to a certain size.

In this specification, the terms one fabric and another fabric are used, but this only means that two fabrics are used, and the futon after completion is used. In either case, one fabric may appear on the front side or the other fabric may appear on the front side. Also, the material of one fabric and another fabric may be different fabrics,
The same dough may be used. That is, a cloth usually used as a dress material may be used as one cloth, and a cloth usually used as a lining may be used as another cloth, or vice versa. Further, for both fabrics, a fabric usually used as a dress material or a fabric usually used as a lining material may be used.

The one dough feeding means (1) is constituted by a belt conveyor in the illustrated example, and the one dough (U)
Is first supplied onto the conveyor from a roll (7) wound by placing one end on the surface of a belt conveyor. In the present invention, one dough feeding means (1) is not limited to a belt conveyor, and any transport device can be used as appropriate. One dough feeding means (1)
The supply of one dough (U) onto the conveyor is performed intermittently. That is, one cloth (U) repeats such a behavior that it stops after being transported for a certain length, and stops after being transported for a certain length. The intermittent cloth (U) supply mechanism may be configured by appropriately combining known devices such as a sensor, a timer, a switch, and a counter. For example, simply using two timers and a changeover switch The motor for driving the conveyor may be driven and stopped at regular intervals, or one cloth (U) may be detected at a predetermined position by a sensor, and based on a detection signal from the sensor. The conveyor may be stopped by switching a switch, and a certain time may be measured by a timer, and after the certain time has elapsed, the switch may be switched again to drive one of the dough feeding means (1). The configuration is not particularly limited.

The surface of one fabric (U) conveyed by one fabric feeding means (1) is perpendicular to the direction of feeding of one fabric (U) by a horizontal tape bonding means (2). Alternatively, the belt-shaped tape (T1) is adhered in another direction.
In the illustrated example, the band-shaped tape (T1) is adhered in a direction perpendicular to the feeding direction of one fabric (U), but it is oblique to the feeding direction of one fabric (U). It may be glued in any direction, or may be glued to any other shape, such as round. As shown in FIG. 2, the horizontal tape bonding means (2) is configured to repeat up and down movements that come into contact with and separate from the surface of one fabric (U), and are conveyed by a fixed length as described above. A belt-shaped tape (T1) is adhered to the surface of the one piece of cloth (U) at regular intervals. Inside the horizontal tape bonding means (2), a band-shaped tape (T1) with an adhesive which has been cut in advance to a predetermined length (for example, the length in the width direction of one cloth) is stored. By the vertical movement of the horizontal tape bonding means (2) in which the band-shaped tape (T1) is stored, the band-shaped tape (T1) is bonded at regular intervals to the surface of one cloth (U) as shown in FIG.

However, in the present invention, the strip tape (T1)
Does not necessarily have to be provided with an adhesive. When a belt-shaped tape (T1) without an adhesive is used, for example, a mechanism for applying an adhesive (for example, a spray or a stamp) to the horizontal tape bonding means (2) Is applied, an adhesive is applied to the surface of one cloth (U) by this application mechanism, and a band-shaped tape (T1) may be applied thereon. Alternatively, a double-sided adhesive tape may be used as the horizontal tape bonding means (2), the double-sided adhesive tape may be first bonded to the surface of the cloth (U), and the strip-shaped tape (T1) may be bonded thereon. The strip-shaped tape (T1) may be a long strip wound on a reel or the like. In this case, a cutter is attached to one end of the horizontal tape bonding means (2), and the strip-shaped tape is used by the cutter. After cutting (T1) to a predetermined length, the band-shaped tape (T1) may be brought into contact with one cloth (U).

A plurality (four in the illustrated example) of vertical tape supply means (3) and other cloth supply means (4) are provided on the downstream side (left side in the drawing) of the horizontal tape bonding means (2). .
The vertical tape supply means (3) is configured to continuously supply the belt-shaped tape (T2) wound on the reel (31) in the transport direction of one cloth (U), and the other cloth supply means (4) )
Is configured to continuously supply another fabric (O) wound around a roll (41) in the transport direction of one fabric (U) from above the belt-shaped tape (T2). In the illustrated example, the belt-shaped tape (T2) is wound around the reel (31), and another fabric (O) is wound around the roll (41). The form of the cloth supply means (4) is not limited to the illustrated example, and may be configured to supply a stripped tape (T2) or another cloth (O).

Downstream of the vertical tape supply means (3) and the other cloth supply means (4), a plurality (four in the illustrated example) of sewing machines (5) are arranged in line. 5)
The other fabric (O) and the vertical tape (T2) supplied to one fabric (U) are sewn together with the one fabric (U).

The sewing by the sewing machine (5) may be continuously performed over the entire length of the cloth, but is performed intermittently so as not to perform the sewing at a portion cut by a cutting device (6) described later. Alternatively, reverse stitching may be performed at a fixed position.

In the present invention, the numbers of the vertical tape supply means (3) and the sewing machine (5) may be set according to the number of the band-shaped tapes (T2) to be sewn. Further, the arrangement intervals of the vertical tape supply means (3) and the sewing machine (5) can be adjusted.
