Is provided, and an upper wall 43a formed on the upper end of the lift 43
The guide bars 45 erected at both ends of the
4 (see FIGS. 1 and 3).

Spring support pins 46 penetrate and are fixed to both ends of the upper wall 43a of the lift table 43. The lift plate 47, which can move up and down along the lift table 43, is provided directly below the two spring support pins 46. A spring support pin 48 is provided, and both ends of the spring 49 are locked by the hole provided at the lower end of the spring support pin 46 and the spring support pin 48 (see FIG. 3). Therefore, the lifting plate 47 is urged upward.

An intermediate portion of the lever shaft 51 is inserted into each of two holes 50 penetrating the elevating plate 47, and a lower end of an extendable lever 52 is fixed to one end of the lever shaft 51. A pressing roller 54 is rotatably provided on the provided roller shaft 53. Telescopic lever 5
The two structures are a square tubular fixed lever 52a fixed to the lever shaft 51, a square tubular retractable lever 52b inserted into the rectangular tubular fixed lever 52a, a fixed lever 52a at both ends, and a retractable lever 52b. And the retracting lever 52
It comprises a spring 55 for urging b in the immersion direction, and a stopper (not shown) for regulating the amount of immersion of the retracting lever 52b (see FIG. 3).

A pinion 56 is fixed to the other end of the lever shaft 51, and the pinion 5 is fixed to a rack 57 fixed to the lift 43.
6 meshes. Accordingly, when the elevator 43 is lowered, the pressing roller 54 comes into contact with the upper surface of the roll-shaped winding material R,
When the elevating plate further descends, only the elevating plate 47 stops descending, so that the right pinion 56 rotates clockwise in FIG. 3, the left pinion 56 rotates counterclockwise in FIG. (See FIG. 3).

In a control panel (not shown) adjacent to the tape attaching device A to the take-up material, there are a 45-degree rotation of the indexing plate 4 and a stop of positioning, reception of a detection signal of the end detection sensor 16, and Each air cylinder 13, 25, 28,
A control unit for instructing the operations of 34 and 41 is provided.

FIGS. 2 (A), 2 (B) and 4 show the operation of the tape adhering device A to the winding material configured as described above.
This will be described with reference to FIGS. FIG.
As shown in (A), the leading end pulled out from the roll-shaped cellotape T bends and passes through the free roller 22,
It is attached to the tape cutter 23. Clamp roller 39
The upper roller 38 and the lower roller 33 are located at the origin positions where they stop above and below the drawn-out portion of the cellophane T, respectively. The pressing roller 54 is at the retracted position at the upper limit.

The winding position S ₂ given roll of winding material wound on diameter R, the positioning stop is sent to the tape adhering position S ₃ Repeat 45 degree rotation and the positioning stop of the indexing plate 4 I do. The air cylinder 13 is actuated, the vertically movable table 15 is lowered, and the holding lever 18 is moved to the winding member R.
Pressing the upper surface, end R ₁ is inhibited from jumping out from the outer circumferential surface of the winding member R, and is prevented from loosening occurs in a roll winding material R (in practice, winding position since the adhesive to the end R ₁ in S ₂ is applied in dots will be stopped loose double) with the laser beam of the end portion detection sensor 16 is in contact with the upper surface of the winding member R (FIG. 2 (A)).

Next, when the collet chuck 7 rotates and the terminal end R ₁ of the winding member R reaches the upper surface of the winding member R, the terminal end detection sensor 16 detects a step generated at the terminal end R ₁ , The collet chuck 7 stops. Accordingly, the winding material R in a roll, is positioned termination R ₁ in a state facing upward.

On the other hand, when the air cylinder 34 is operated and the clamp roller 39 clamps the drawn portion of the cellophane tape T, and the air cylinder 34 is operated and the clamp roller 39 is raised, the tip of the drawn portion of the cellophane tape T is taped. Move away from the cutter 23 (see FIG. 4B). Next, when the clamp roller 39 holding the drawn-out portion of the cellophane tape T is horizontally moved to just above the roll-shaped winding material R by the operation of the air cylinder 25 and stopped, the air cylinder 2
8, the clamp roller 39 descends, and the drawn part of the cellophane tape T hits the tape cutter 23 during the descent, and is cut off. Contact (Fig. 4
(C) see) to secure the terminating R ₁ to the outer peripheral surface of the roll-like winding material R.

Since the holding lever 18 has finished its function,
The air cylinder 13 is actuated to raise the vertical platform 15 and return it to the position shown in FIG. On the other hand, the air cylinder 34
, The clamp roller 39 is opened, the air cylinder 41 is operated, the elevator 43 is lowered, and the pair of pressing rollers 54 abut against the upper surface of the cut piece of cellophane tape T '(see FIG. 4 (D)). Since only the elevating plate 47 stops, the pair of pressing rollers 54 rotate in the direction in which the levers 51 are supposed to open each other.

Since the pressing roller 54 rotates about the lever shaft 51 as a fulcrum, the rotation locus does not coincide with the outer peripheral surface of the roll-shaped winding material R. To eliminate. Since the lever 52 is urged in the shortening direction, the pair of pressing rollers 54 move to both ends of the cellophane tape cut piece T 'while pressing the cellophane tape cut piece T', and the cellophane tape cut piece T 'is rolled. It adheres securely to the outer peripheral surface of the material R. On the other hand, the clamp roller 39 returns to the original origin position (FIG. 4).
(Refer to (E)), one cycle of the automatic application of the tape is completed.

The adhesive tape cut pieces T 'is the winding material R automated stuck roles shape, by the intermittent rotation of the indexing plate 4, it is sent to the carry-out position S _4, out of the collet chuck is clamped by the unloading hand Is carried out. Until a roll winding material R is inserted into the case of the filter, cellophane tape cut pieces T 'remains is adhered, by preventing jumping out of the roll of winding material R loosening or terminating R ₁ But peels off when inserted into the case. Since the cut piece of cellophane tape T 'can be easily turned off, the peeling operation is simple.

[0029]

Since the present invention is configured as described above, it has the following effects. (1) The tape affixing apparatus for a winding material according to the present invention detects that the end of the rotating roll-shaped winding material is at the top, stops positioning of the winding material, and rolls and winds the end. The adhesive tape is brought into contact with the outer peripheral surface of the material, and the pressing roller moves along the adhesive tape while pressing the adhesive tape, so that the adhesive tape is securely attached. (2) Since the tape sticking apparatus of the present invention is automatically and continuously performed efficiently, the operator is freed from troublesome sticking work and greatly reduces the sticking cost. Has the effect of doing (3) The end of the rolled material is stopped by a piece of adhesive tape, so it can be easily peeled when inserting the rolled material into the case. It became easier.
