Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for quickly, reliably and easily separating a connected cloth formed by connecting a plurality of part cloths for each part cloth. And a separating device. 2. Description of the Related Art Generally, a body,
A plurality of parts cloths such as sleeves and collars are sewn together, and these parts cloths are small pieces or small cylinders provided around the cuffs and neck, such as those called horizontal rubber. Some are relatively small in shape. In such a part cloth, after knitting as a long cloth in the shape of a band or a cylinder, dyeing and salasing etc. are completed,
After that, cutting or threading was performed to the required length for the part fabric. [0003] However, the cutting and threading operations are also troublesome and require skill. Therefore, at the stage of knitting as a long fabric, it is necessary to make the connecting portion easy to remove the thread, or to knit the connecting portion with a water-soluble thread to facilitate separation of each part fabric. It is considered. [0004] Neither the method of removing the connection portion from the connection fabric nor the method of dissolving the connection material with water has provided the work efficiency as expected. . In particular, the method of dissolving with water requires large-scale equipment, and further increases running costs.
There were also disadvantages. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been made in view of the above circumstances, and has been made so that each part cloth can be quickly, reliably and easily separated from a connected cloth in which a plurality of part cloths are connected in series. It is intended to provide a device. In the present invention, the following technical means have been taken in order to achieve the above object. In other words, in the separation device according to the present invention, the feeding means for transporting the connection cloth formed by connecting the part cloths through the connection part by the molten yarn in the connection direction, and the connection of the connection cloth conveyed by the feeding means The heating unit has a heating unit that separates each part dough by heating the parts, and a sending unit that conveys each separated part dough toward the collection position. [0007] As described above, the connecting cloth is formed by knitting a connecting portion with a molten yarn, and the heating means includes, for example, a hot air generator capable of blowing hot air to the connecting cloth, and a heating element disposed close to the connecting cloth. By a possible heating device, or an electromagnetic wave irradiation device that generates microwaves etc. toward the connected dough,
Since it is only necessary to heat the connecting portion of the connecting cloth, an extremely simple device configuration can be obtained. In addition, the separation into the parts fabric can be performed with high efficiency. It is simplest to employ a configuration using a hot air generator. When a hot air generator is used as the heating means, if a posture holding means that can move in synchronization with the connecting cloth is provided in a region opposite to the connecting cloth from the hot air blowing portion, the connecting cloth (that is, the part cloth) There is an advantage that it is possible to prevent a wrinkle, meandering, turning over, and complexion while suppressing flapping of the state (before separation) and parts cloth (that is, the state after separation), thereby enabling reliable conveyance at a constant pitch. . Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a separation device 1 according to the present invention as a core, a supply device 3 for connecting dough 2 on its primary side, and a collecting device 5 for parts dough 4 on its secondary side. It shows what made a series of dough separation steps. In this dough separating step, the connected dough 2 to be set in the supply device 3 is knitted in a belt-like shape as shown in FIG. 5, so that each part dough 4 is separated at the knitting stage. A thin connecting portion 6 that crosses in the width direction is provided. This connecting portion 6 is knitted by a molten yarn. As the molten yarn, a yarn having a relatively low melting point of about 200 ° C. (for example, a low-melting polyester yarn or a low-melting nylon yarn) is used. Note that one end in the width direction of the connecting portion 6 includes a thread used for knitting of each part fabric 4 as a straight jumping thread (see reference numeral 4a in FIG. 4).

The hot air generated by the hot air generating device 23 is, of course, in a range that does not adversely affect the thermal effect on the part cloth 4 and the molten yarn used for the connecting portion 6 of the connecting cloth 2 is removed. The temperature is adjusted to a temperature at which melting is possible (around 200 ° C.). The supply timing of the hot air by the hot air generator 23 may be set only when the connecting portion 6 of the connecting fabric 2 reaches the jetting portion, or may be continuous during the transport of the connecting fabric 2. When the connecting cloth 2 is not supplied to the feeding means 10, it is appropriately detected by a sensor (not shown) so that the hot air generator 23 does not operate. The attitude holding unit 25 includes a free roller 30 provided adjacent to and upstream of the upper roller 19 of the pinch roller mechanism 17 disposed on the upstream side of the feeding unit 10. 10 a pinch roller mechanism 1 arranged downstream
