CONSTITUTION:After proper length of tape (t) is delivered and stuck, if a pressing roll 7 is pushed against a stuck surface while a case 1 is further strongly pushed down resisting a spring 6, a link 13 rotates causing an engaging pin 16 to stop being engaged with a long hole 15, a movable board 9 is retracted in a direction separating from the pressing roll 7, causing the roll of tape (t) to be stretched between the roll 7 and a winding core 12 while, at the same time, an elevating rod 19 is lowered by means of the link 13 and the piece of stretched tape (t) is cut by means of a cutter 20. After that, when the force pressing down the case 1 is relaxed, the case 1 is raised due to the spring 6, the link 13 rotates clockwise centering around a fulcrum shaft 14, the cutter 20 is raised through the elevating rod 19, and the roll of tape (t) after cut off is brought in contact with an entangling prevention board 29, without being caught in the cutter 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an invention of a simple tape feeding device that can stick an adhesive tape while feeding it by Jl operation and cut it at a desired length at the edge.

In the present invention, a cutter is provided so as to be movable up and down between the pressure roll that pushes the adhesive side of the adhesive tape onto the surface to be adhered and the winding core of the tape, and the winding core is also provided so that it can move forward and backward in conjunction with the cutter. When cutting the tape, the cutter is lowered and the winding core is moved backward to tension the tape, thereby ensuring that the tape is cut νJ. And after cutting the tape, raise the cutter? ? At the same time, the winding core is advanced, and the tip of the tape cut by 9J is sent to the F side of the suppression roll in preparation for the next pasting operation.At this time, the winding core is advanced until the cutter rises a certain distance. After the canter is completely separated from the νJ section of the tape, the winding core is moved forward, thereby preventing the cut end of the tape from being caught in the J-51 of the canter while still attached to the cutter. Prevent,
The leading edge of the tape is sent out correctly below the suppression roll. As described above, an object of the present invention is to efficiently apply tape 1 by accurately cutting the tape and feeding out the leading end of the tape after cutting.

To explain the embodiment shown in the drawings, 1 is a case with an open bottom, and a support shaft 2 is horizontally suspended at the rear end of the bottom.

Reference numeral 3 denotes a take-off plate along the inner surface of the side wall of the case 1, on which a bearing cylinder 4 provided at the rear end of the bottom 1 is pivotally attached to the support shaft 2, and the support +1III
+ 2 is the center number ζ, and the ζj plate 3 is connected to the case 1 so as to be rotatable. Reference numeral 5 denotes a bottom plate that is connected to the bottom of the supplementary plate 3, and connects both ends of the coil spring 6 wound around the outer periphery of the bearing tube 4 to the back of the bottom plate 5 and the case l, respectively. In this case, the elasticity of the press roll 7, which is provided at the front end of the bottom of the plate 3, is pushed out from the open bottom surface of the case 1 by sealing the extra issue &3. Reference numeral 8 denotes the front wall of the case L, and its edge abuts against the supplementary issue plate 3 L7, which plays the role of a spring plate.

9 is a moving board along the supplementary board 3, and its 1i rows on both sides are I.
It fits into the guide rail 10.10 that extends over the cover plate 3, and allows the movable plate 9 to move forward and backward with respect to the supplementary plate 3 so as to move forward toward the pressure roll 7 or retreat further than the pressure roll 7. Install. Part 1. A tape support 1'l is integrally fixed to the plate surface of the movable plate 9, and a winding core 12 of the adhesive tape L is rotatably attached to the outer periphery of the tape support 1'l.

Reference numeral 13 denotes a link that is pivotally attached to the fulcrum shaft 14 of the mounting plate 3, and is inserted into the gap between the take-up A/J plate 3 and the movable plate 9, and a long hole 15 bored in the inner end thereof is inserted into the back side of the movable plate 9. and tape support 11
It loosely fits into a retaining pin 16 formed at a position corresponding to the center of.

Reference numeral 17 denotes an I/if rod that protrudes from the inner surface of the side wall of the case l and engages with the guide slot 18 of the link 13.

19 is a land rope 1 equipped with a canter 20 at the lower end, its two wheels are connected to the connecting hole 2 through the shaft 21 at the outer end of the link I3, and The formed concave groove 22 is slidably engaged with a guide protrusion 23 formed within the front peripheral frame of the supplementary issue plate 3.

24, 25 and 26 are guide plates made of thin iron plates bent into a U-shape, and guide the adhesive tape L by their two parallel edges. 2
6 is added to the mobile board 9 via the branch office 27. Then, the horizontal II of the guide plate 25 attached to the movable plate 9 is formed narrower than the guide plate 24 attached to the supplementary issue plate 3, so that the guide plate 25 is moved inside the guide plate 24 as the movable plate 9 advances and retreats. In addition, the edges of the guide plates 24 to 26 are formed so as to substantially follow the straight line connecting the center of the pressure roll 7 and the tape support 11.

゛The inner plate 24 has a cutter 20 and a roll prevention plate 2 in the 1/row.
9 is added and its lower edge is exposed behind the suppression roll 7.

Then, the tip of the adhesive tape t made of cellophane or acetate is inserted between the guide plates 24, 25, and 26 through 111.
Then, with the glue side facing up, guide it to the end of the pressing a-luer (Figure 1).

Then, hold the case l with one hand and press it onto the tape t through the roll 7.
(tip of the tape) 11, then press the case L, compress the spring 6, press the tip of the tape, and then press the entire device. When the tape is moved in the opposite direction, the winding core 12 rotates and the edge of the tape t comes out and is stuck (FIG. 2).

When the spring 6 is compressed in this way and the plate 3 is rotated about the supporting shaft 2 with respect to the case l, the supporting shaft 1 of the supplementary plate 3
4 rises relative to the fixed shaft 17 of the case l, the link 13 rotates counterclockwise about the fulcrum shaft 14 in FIG.

At this time, the cutter 20 descends, but does not come into contact with the tape holder yet. Further, the engagement pin 16 of the movable plate 9 continues to move relatively from one end to the other end within the elongated hole 15, and the relative positions of the movable plate 9 and the mounting plate 3 do not change.

After unwinding and pasting the tape t of the appropriate length, the case l is pushed down even more strongly against the spring 6 while pressing the pressure roll 7 against the surface to be pasted.

As a result, the link 13 rotates, the engagement pin 16 is locked in the elongated hole 15, and the movable plate 9 retreats in a direction away from the pressure roll 7 to tension the tape t between the pressure roll 7 and the winding core 12. At the same time, the elevator shuttle 19 is lowered by the link 13, and the cutter 20 cuts the tensioned tape t (
Figure 3).

After that, when the force to push down the case 1 is weakened, the elasticity of the spring 6 causes the case 1 to move up to 2>4L, and the link 13 is attached to the fulcrum shaft 1.
4 in the clockwise direction, and the canter 20 is rotated clockwise through the lifting rod 19. (Figure 4).

At this time, the tape t after cutting P comes into contact with the winding city prevention plate 29, so that it is not wound up by the cutter 20 moving upward y1, and the cutter 20 separates the tape more completely.

Cuff 920 is J: ! When the engagement pin 16 moves relatively within the elongated hole 15 at first, the moving plate 9 does not move even if the link 13 rotates. turns 1ij1, canta 2
0 is above the pressure roll 7), then the elongated hole 1
5, the engagement pin 16 is engaged with the moving plate 9t, and the pressing roll 7
The tape t moves forward in a direction approaching , sends out the pJ cut end of the tape t below the suppression roll 7, and returns to the original position shown in FIG.

In this way, when the canter 20 rises after cutting νJ of the tape t, the movable plate 9 does not move forward at the same time as the upper part 1 of the cutter 20;
is raised to a predetermined height and is completely separated from the tape t by the entanglement prevention plate 11 and the plate 29, and then the movable plate 9, that is, the winding core 12 of the tape t, starts to move forward, so that the tip of the tape L is attached to the cutter 20. There is no risk that the tape will adhere and move up with the canter 20, and the tip of the tape t should be pressed correctly.
- sent out below the lure in preparation for the next sticking operation;

Note that the same effect can be obtained by forming the connecting hole 28 at the outer end of the -link 13 into a long hole instead of the long hole 15. Also, link 1
Even if the engagement pin 16 is formed in the movable plate 9 and the elongated hole 15 is formed in the movable plate 9, the gist of the present invention does not change.

However, in the present invention, when the tape is cut, the tip of the tape is always sent out to the lower blade of the pressure roll 7 by the forward distance of the movable plate 9, so the tape L is pressed against the surface to be pasted by the suppression roll 7, and the tape L is When (1) is cut with the cutter 20 without moving, a tape with a length equal to the forward distance of the movable plate 9 is immediately cut (lI), and, for example, it is made like a thumbtack (∆) to attach the tape to the drawing board. Convenient.

In short, in the present invention, the cutter 20 is installed between the tape support 11 which rotatably supports the winding core 12 of the adhesive tape t, and the press roll 7 which presses the adhesive side of the adhesive tape t onto the surface to be adhered. The cutter 20 is forced 4=I in the -L direction by the spring 6, and the tape support 11 moves forward and backward toward the pressure roll 7. When the force and the lever 20 are lowered, the tape support 1
1 retreats, and the force ν 20 becomes -l Niji 1. When the tape support 11 moves forward, the link 1 interlocks the tape support 11 with the tape support 11.
3, the canter 20 is lowered to cut the tape, and the tape is under strong tension (7
Therefore, the tape t can be cut into a tub by the falling cut 20.

After cutting the tape, while raising the cutter 20, turn the winding core 12 of the tape support '11 towards the pressure roll 7.
The leading edge of the tape t which has been cut by ij and pj is sent out. At this time, in the present invention, the cutter 20 or the tape support 11 is
and link 13 are connected by an elongated hole 15 and an engaging pin 16 loosely fitted therein, and the engaging pin 16 is connected to the elongated hole until the cutter 20 reaches a certain ratio a]-H from the bottom dead center after cutting the tape. 15 to move the tape support 11 forward, the cutter 20 remains stationary for a while, and the tip of the cutter 20 touches the tape t.
Since the tape support 11 starts moving forward after the tape support 11 has been separated more completely, there is no risk that the tape t just cut will adhere to the cutter 20 and l jL together with the cutter 20.
The tip of the tape t is correctly sent out below the suppression roll 7, and you can immediately move on to the next application operation, allowing you to efficiently and repeatedly make the adhesive tape to any length! , 7J has the effect of being able to be pasted while being cut.
