Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a machine for manufacturing a bundle of plastic tapes such as pompons used for sports support, mass games, parades, etc., and more specifically, a thin plastic tape in the longitudinal direction thereof. It is intended to cut along a certain width into a certain width, cut this into a certain length, and bind at the center.

(Prior Art) Conventionally, a pompon is a roll-shaped plastic tape having a width of about 5 cm, cut into a length of about 60 cm to 100 cm to form a large number of strip-shaped tapes, which are overlapped and folded in two. The bent portions are tied with a string, and each tape is torn from the end into a width of about 5 mm or cut with a knife.

(Problems to be solved by the invention) However, when such a conventional method is used, it takes a lot of time and effort to manufacture, so in a school, kindergarten, etc. where pompons frequently act, complicated mechanical power is required. There has been a strong demand for a low-priced, simple pompon making machine that can be used easily without using electric power.

(Means for Solving the Problems) The present invention is intended to meet such a demand,
In the front part of the frame, there is a spindle that supports the rolled plastic tape, and a slitting device in which a number of cutters that split the plastic tape into narrow widths are connected in parallel at regular intervals in the width direction of the plastic tape. At the rear of the frame, a take-up reel of plastic tape that has been slit into a narrow width is rotatably attached to the shaft. The take-up reel outer peripheral surfaces are opposite to each other with the center axis of the take-up reel interposed therebetween. At the position, a binding cord and a concave portion for inserting a knife are provided opposite to each other. The cutter may have a rectangular plate shape such as a razor blade, or a disk shape.

(Operation) After the tip of the roll-shaped plastic tape rotatably supported on the spindle is fixed to the outer peripheral surface of the take-up reel by passing the lower side of the cutter, the take-up reel is rotated to form the plastic tape. Is cut into a narrow width by a large number of cutters and wound up on a take-up reel in an orderly manner. After rotating the take-up reel a predetermined number of times, insert a binding cord into one of the recesses formed on the outer periphery of the take-up reel to bind the tape in this part, and insert a knife into the other recess to insert the knife in this part. When the plastic tape is cut and the plastic tape is cut between the slitting device and the take-up reel, a bundle of narrow tapes having the central portion bound is formed as shown in FIG. This is folded in two at the binding portion, further bound at a portion in the vicinity of the bent portion, and then each narrow tape is folded back in the opposite direction to form a pompon. In addition, the bundle thus formed is folded in two at the binding portion,
If the handle is fixed to the bent portion, a cleaning duster is formed.

(Embodiment 1) FIG. 1 shows an example of a machine for manufacturing a plastic tape bundle for forming a pompon according to the present invention.
This pompon making machine has a frame 1. The frame 1 has a pair of right and left vertical side plates 2 that are opposed to each other in parallel with a constant space therebetween, and is mounted on a pace 3 with screws or the like. Between the side plates 2, a cleaving device 4 is installed on the upper part on the front side, and a take-up reel 5 is rotatably supported by a reel shaft 6 on the upper part on the rear side.

A slit 49 through which the tip 9a is inserted and a U-shaped recess 50 for locking the hook 45 are provided. The flanges 43 on both sides are provided with holes 51 that are continuous with the two recesses 48 of the flat portion 46 and that widen the opening area.

The reel shaft 6 is a bearing fixed to the left and right side plates 2 of the frame 1. A handle 53 for manually rotating the take-up reel 5 is attached to one end of the reel shaft 6.

Next, an example of use of the machine for manufacturing a bundle of plastic tapes for pompons will be described.

The tape roll 11 is attached to the side plates 2 on both sides by the roll support shaft 7.
While supporting the cutter holder 31 of the slitting device 4 in the upper retracted position as shown in FIG. 3 while holding the tension lever 15, the plastic tape 9 is pulled out from the tape roll 11 and the guide roller 13 is supported. After that, the cutter holder 31 and the slitting table 23 are directly passed through. Then, the tip 9a of the tape 9 is inserted into any one slit 49 of the winding body 51 of the winding reel 5, and the tip 9a is hooked and tied in the recess 50 to be hooked on the winding body 45. After that, the cutter holder 31 is lowered and held in the state shown in FIG. 2, and the large number of cutters 34 are cut into the tape 9 in the large number of strips 25 of the slitting table 23 as shown in FIG. When the take-up reel 5 is rotated by the handle 53 in this state, the tape 9 passes between the cutter holder 31 and the slitting base 23 while being pulled out from the tape roll 11 and guided by the guide roller 13, and at that time, a large number of cutters It is cut into a certain narrow width (about 5 mm) in parallel with the longitudinal direction by 34 and wound up on the winding body 45 of the winding reel 5. The take-up length can be estimated from the number of revolutions of the take-up reel 5 or the take-up thickness of the tape 9 on the take-up barrel 45, so that when the desired amount is reached, the take-up reel 5 After the string 54 is inserted into one of the pair of recesses 48 located above and bound, the take-up reel 5 is rotated half a turn to position the other recess 48 above, and the recesses 48 are put together with scissors or the like. When cut and removed from the take-up reel 5, a tape bundle in which the central portions of a large number of finely cut tapes 9b are bound by a string 54 is obtained as shown in FIG. This tape bundle becomes a target pompon by simply loosening the both sides of the overlapping shredded tapes 9b, or by further providing a means for finger hanging in the central portion where they are bound. The side plate 2
It is convenient to provide a known counter that mechanically counts the number of rotations of the take-up reel 5 at an appropriate position.

(Embodiment 2) FIGS. 10 to 13 show another embodiment of the present invention. The major difference between this example and the previous embodiment lies in the structure of the ripping device for ripping the tape 9, and the other parts are substantially the same although there are slight differences, and are designated by the same reference numerals in the drawings. The cleaving device 55 in this example uses a rotating cutter assembly 56. As shown in FIG. 11, the cutter assembly 56 is formed by fixing a large number of circular cutters 58 to a cylindrical core 57 in parallel at regular intervals in the axial direction, and between the left and right bearing plates 60 of the cutter holder 59. Axis 61

Even if the lock pin 82 is gripped by the knob 86 and the lock pin 82 is slid leftward against the spring 83 as shown in FIG.
Since the lock pin 82 is engaged with one end of the recess 84 to regulate the sliding of the lock pin 82, the tip of the lock pin 82 cannot be pulled out from the hole 88 of the lock piece 89, and accordingly, the mounting frame plate 65 Can't open. However, if the cutter holder 59 is lifted and held in the upper position with respect to the mounting frame plate 65 as shown by the chain line in FIG. 13, the protrusion 87 of the cutter holder 59 comes off from the recess 84 as shown in FIG. The lock pin 82 can be slid to the left against the spring 83 and pulled out from the hole 88 of the lock piece 89, and the mounting frame plate 65 together with the safety cover 77 should be opened as shown by the chain line in FIG. You can

In addition, in the example shown in FIGS. 10 to 13, the support shaft 7 has a cylindrical portion.
The cylindrical core 92 rotatably supports the core 10 of the tape roll 11.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical idea thereof. The machine according to the invention can also be used for making not only pompoms but also other plastic tape bundles of the same kind.

(Effects of the Invention) As described above, the present invention is adapted to the winding drum because the roll-shaped plastic tape supported on the support shaft is slit into a narrow width by the cutter of the slitting device and wound up on the winding reel. A bundle of narrow tape can be easily manufactured by inserting a binding cord into one of the recesses provided and binding this part, and inserting a knife into the other recess to cut the tape. It is possible to mass-produce pompons and the like easily and at low cost simply by folding in two at the binding portion and further binding this portion.
