Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape supporting device in a sewing machine.

[0002]

[Prior art]

 The tape support device that is sewn with conventional sewing machines is for production plants that are used in combination with industrial sewing machines for mass production used in sewing factories, etc. Since it is a large-sized machine that is installed separately at a different position, no inconvenience occurred even when the sewing machine was not in operation without considering storage, but when used for home use, it was too large and difficult to handle. In addition to that, there were various problems in terms of storage.

[0003]

[Problems to be solved by the device]

 The present invention is that the supporting device for supporting the tape can be stored when the sewing machine is not used, and the structure is such that it can be easily replenished from the large reel of the tape to the reel of the tape supporting device.

[0004]

[Means for Solving the Problems]

 In the present invention, a reel mounting base for supporting the reel is detachably provided at an appropriate position of the machine frame of the sewing machine, so that the tape supporting device can be miniaturized and improved in mobility, and can be stored. A long narrow hole is provided on the tape to facilitate tape winding and to supplement tape winding.

[0005]

[Action]

 According to the present invention, a reel mounting base integrally formed with a detachable fixing portion, a tape guide hole and a reel mounting shaft is provided on a sewing machine frame, and a rotatable reel is supported on the reel mounting shaft. By providing small holes in the radial direction in the radial direction, the tape support device is integrated with the machine frame of the sewing machine, thus improving the mobility together with the sewing machine and winding a small amount of tape of the desired color. It is possible.

【Example】

 A structure of an embodiment of the present invention will be described below with reference to the drawings. A drive shaft (not shown) driven by an electric motor (not shown) is rotatably supported in a sewing machine frame 1 and the drive shaft A needle bar 2 that moves up and down in association with rotation is supported, and a needle 3 is fixed to the lower end of the needle bar. A presser bar 5 to which a cloth presser 4 is fixed is slidably supported at the lower end of the sewing machine frame 1.

A thread stand portion 6 for mounting a bobbin (not shown) is provided on a back surface portion of the sewing machine frame 1, and a plurality of thread stand portions 6 are provided on a front surface portion for applying a tension to a thread guided from the bobbin winding machine. Yarn x tensioners 7, 8, 9, 10 are provided, and a plurality of needle thread guides 11, 12 for changing the traveling direction of the yarn are provided at appropriate positions.

A needle plate 14 is attached to the lower sewing machine frame 13 at a position where the cloth presser 4 abuts, and a looper, a feed dog and the like (none of which are shown) are provided below the needle plate. ing. A reel mount 15 is detachably provided at an appropriate position on the sewing machine frame 1. The reel mount is integrally constituted by an arm 17 having a fixing portion 16, a guide arm 19 having a tape guide hole 18 and a support arm 21 for horizontally fixing a reel support shaft 20. Then, the fixing portion 16 is fixed to the sewing machine frame 1 with the tightening screw 34.

A reel 22 is rigorously mounted and rotatably supported on the reel support shaft 20. The reel is provided with flanges 23 and 24 on both sides, a shaft portion 25 for mounting a tape is provided between the flange portions, and a hole portion 26 for inserting the reel support shaft 20 is provided in the center. In addition, a finger-holding handle 27 and a narrow hole 28 elongated in the radial direction are provided at appropriate positions on the side surface of the flange portion. A circular hole 29, which is wider than the width of the fine hole, is provided at the end of the fine hole.

An adjusting screw 31 having a knob portion 30 is screwed onto a vertical support arm 21 of the reel mount 15, and the tip of the adjusting screw 31 is attached to another flange 24 of the reel 22. It faces the outside at a right angle. The reel 22 is tightly mounted on the reel support shaft 20, and is held by the jaws of a fixing screw 33 screwed into a screw hole 32 provided at the shaft end of the reel support shaft.

The present invention is configured as described above, and therefore operates as follows. A reel mount 15 on which a reel 22 is rotatably supported on a reel support shaft 20 of the support arm 21 is fixed to the sewing machine frame 1, and the reel 22 of the present invention is replaced with another reel of thick winding. Take up part of the tape T. The end portion of the tape T to be wound is fixed from the inside of the flange 23 to the outside through the fine hole 28 and fixed with a finger, and the handle 27 is rotated to wind the tape T on the reel 22.

The tape T wound on the reel 22 is guided downward from the tape guide hole 18 and passes through between the thread tension regulators 7, 8, 9, 10 and the needle thread guides 11, 12 to perform their functions. It is pulled out below the tape presser foot 4 so as not to damage it. When the sewing machine is operated in this manner, the needle 3 and the looper cooperate with each other due to the vertical movement of the needle bar 2 to sew the cloth, and the tape T is sewn on the cloth. The rotation of the reel 22 is restricted by the operation of the adjusting screw 31.

[0013]

【effect】

 Since the present invention has the above-described structure and operation, it is possible to wind an appropriate amount of tape from another large reel of tape reel onto the reel of the present invention, and at the same time, to the tape guide portion of the machine. Since the tape is fixed, the guideability of the tape is good, and since the tape support device is fixed to the machine frame of the sewing machine, it can be moved together with the sewing machine.
