Abstract

PURPOSE:To quickly wind a tape to fixed hardness by pressing the upper surface of the tape on a table with a presser plate as a slide shaft descends and bringing the slant face of a drive shaft into contact with the inner surface of a tape wind core so as to force-rotate the wind core. CONSTITUTION:A foot pedal 27 is depressed to lower a slide shaft 14, consequently a rotary shaft 15 is lowered, and when it is engaged with a clutch 13, a microswitch 22 is operated to drive a motor 12. The pedal 27 is further kept depressed, the upper surface of a tape 1 is pressed with a presser plate 17, the slide shaft 14 continues its descent while this pressing force is increased by an action of a spring 19, the slant face of the rotary shaft 15 is brought into contact with the inner diameter of the wind core 2 of the tape 1, the wind core 2 is rotated by the friction force between the wind core 2 and the rotary shaft 15 to wind the tape 1. After the tape 1 is wound to fixed hardness, the foot is released from the foot pedal 27, the slide shaft 14 is raised by the force of the spring 28, the motor 12 is stopped, and the wound tape 1 is shifted sideways and removed from the wind core 2.

Description

DETAILED DESCRIPTION OF THE INVENTION For example, this 36-inch paper tape is used for the paper-wrapped conductor of a variable FT. This relates to a monitoring device used when winding up.

To make a reel-shaped tape like the one described above, a slitter or the like is generally used to cut a wide base paper into tape shapes, but the width of the tape is extremely small compared to the diameter of the tape that is cut out. In the case of VC, there was a risk that the removed tape would be destroyed in the subsequent process.

To prevent this collapse, it is possible to wind the tape onto a reel with a hub, as is the case with magnetic tape, but depending on the structure of the tape mounting device (for example, a conductor paper winder) in the subsequent process, etc. Reels with no-pu may not be available. In addition, if narrow tapes that are prone to such collapse are requested less frequently, and a tape with a culm width that does not normally cause collapse is requested, VC may modify the tape loading device. It may be economically disadvantageous to do so. In order to prevent a narrow tape from collapsing, there are other ways to prevent the tape from collapsing. It is possible to reach the 14 mark by winding the tape tightly, but reducing the diameter of the wound tape increases the number of tapes and reduces the efficiency of subsequent processes, which is not a preferable method. Therefore, in the past, it was not possible to wind the tape tightly, but since there is a limit to how hard the tape can be wound using the aforementioned slitter, it was necessary to take some additional steps to make it stick even more tightly.

An example of a conventional method for winding a tape to a hardness that exceeds the ability of a slitter will be described with reference to FIGS. 1 and 2.

Figure 1 is a plan view and a side view of the wound tape.
1) is the tape, and (2) is the core. A is tape (1)
It is fixed to the winding core (2) by, for example, gluing at the starting end. B is the winding end of tape (1).

Figure 2 is a diagram showing the method that has been used to keep the tape firmly in place, showing (1) and (2) the above-mentioned tape and core, (3) a backing plate, (4) a hammer, The shout is the workbench table. To keep an eye on the tape,
First, while holding the core (2) with one hand, pull the end B of the tape (1) with the other hand. Roughly, the IJ core (2) was rotated in the opposite direction to the winding direction of the tape (1) to wind up the pulled tape (1), and this operation was repeated several times.

By the way, such manual work is extremely primitive and not only takes a long time, but also because the cut surface of the tape (1) becomes uneven while cutting the tape (1). Place the backing plate (3) on top of ) and tap the backing plate (3) lightly with, for example, a hammer (4).
' [1] had the disadvantage that both sides had to be smoothed.

This invention was made to eliminate the above-mentioned drawbacks.
The purpose of this invention is to provide a winding device that can shorten working time and obtain a uniform tape. An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Figure 3 shows the state before the start of cutting, and Figure 4 1'
The state in which the paper is being wound is shown. In the figure, (
1) is a tape, (2) is a winding core, 0 (ITri, a workbench table with a particularly smooth h surface (for example, a synthetic resin is pasted on the top surface), (tOFL) is an opening, and C111 is a workbench with a top surface Thrust bearing embedded on the table α0 so that it is flush with m, G2 is electric!loJ machine, 03 is one side of the clutch fixed to the shaft of T transmotor (2), a,

At the end of the station 1) A conical rotating shaft attached to iiA,
Its tip has a structure that can be fitted into the clutch C11. 071 is a radial bearing for rotating around the rotation axis 011, and 071 is a pressing plate with a smooth surface to press the top surface of the tape (1) (transparent synthetic resin plate etc. is preferable)

(C) is the upper crank, ◇→ is the connecting shaft, (A) is the foot pedal slope. These are connected to each other with pins to form a sliding link with a sliding axis of 0 fathoms.

2) is a hanging tension spring for balance, which applies a tension slightly larger than the gravity of 041 to (E) in a state where no external force is applied to this device, so as to maintain the slide axis 0→ at the upper limit. It has a structure that can be adjusted to (E) is a fixture for fixing the winding end B of the tape (1), which is attached to the table αQ. Fixtures-
The fixing force shall be adjusted appropriately by adjusting the spring. However, even if the fingertips of the hand are used instead of the fixture, it is possible to sense a sufficiently practical subtle force.

Next, the procedure and operation when using this device will be described. First, place the tape (
1) so that the inner diameter of the core (2) and the inner diameter of the thrust bearing circle almost match, and place the end B of the tape (1) on the fixture CI! Fix it with IK or pinch it with your fingertips.

Next, when the foot pedal is depressed, the slide shaft 0 fathom begins to descend, and along with this, the rotation shaft 06 also descends, and when it engages with the clutch σ, the micro switch is activated. Start. If you continue to press the foot pedal (5) roughly, the presser plate (17) will release the tape (").
), and the action of the spring OI presses the VC.
The slide shaft 0◆ continues to descend while increasing the force, and the slope of the rotating shaft OG becomes VC so that it contacts the inner diameter of the core (2) of the tape (1). At first, the space between the winding core (2) and the rotating shaft oG is slipping, but if you roughly apply force to the foot pedal @,
The frictional force between the winding core (2) and the rotating shaft aQ increases, and the winding core (2)
The tape (1) begins to rotate simultaneously, and the tape (1) is wound up. When the tape (1) has been wound to a predetermined degree of hardness, the end B of the tape (1) will come off from the fixing tool or the fingertip Th
ml, and at this time, when you immediately take your foot off the foot pedal (a), the slide shaft 041 is pulled up by the action of the spring, and at the same time, the action of the microswitch (2) raises the slide shaft 041 to 1. (The rotation of one arm stops. In this way, move the unwrapped tape (1) sideways and repeat the process with a new tape. Immediately after the latch O and the rotating shaft Uυ are engaged. The reason why the electric motor 0 is rotated and stopped just before it is released is to take safety tf+i into consideration.

As described above, according to the present invention, it is possible to obtain an apparatus k that can perform the work of winding and rewinding a sticky tape or string-like material at low cost and safely.
