Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape end positioning device which is applied to a tape end joining machine for overlapping and joining together various tape ends having a certain degree of rigidity, and the positioning device. Tape joining machine.

[0002]

2. Description of the Related Art Generally, various kinds of tapes are often used as long as one kind of tape as they are, but in many cases, such as a hair band or a packing tape, the ends are joined together. Further, for example, in various medical tapes, the tape ends may be joined to each other to add a new tape. Further, for example, in the case of a surface fastener in which a female member having a large number of loop pieces on the surface of a tape-shaped base material and a male member having a large number of hook pieces on the surface of the tape-shaped base material are pressed together and surface-bonded. Often, the male member and the female member are connected in the longitudinal direction and used for various binding bands and other uses.

[0003] As a joining technique of such tape ends, for example, Japanese Patent Publication No. 52-14659 and Japanese Utility Model Publication No. 2-46.
Japanese Patent Application Publication No. 999 discloses a method for joining the end portions of the surface fastener tape. Of these, Tokiko 52-146
No. 59 discloses a joining technique in which the ends of a fastener tape are overlapped and joined via an adhesive. In general, since the fastener tape is thick due to the engaging elements (loop pieces and hook pieces) on the surface, when these are overlapped and joined, the joined portion further increases in thickness, and the commercial value is significantly impaired. According to the publication, in order to eliminate such inconveniences, after removing the engaging element protruding from one of the joining ends, the joining element is joined and integrated with the other joining end via an adhesive. is there.

According to Japanese Utility Model Publication No. 2-46999, a fixed gripper for holding one of the tape ends facing each other, and a gripper for holding the other of the tape ends in a horizontal direction toward the fixed gripper. And a moving gripper that moves forward and backward, and ultrasonic welding means is provided between the two grippers and near the fixed gripper. The movable gripper is arranged stepwise so as to be higher than the fixed gripper by the thickness of the tape. At the time of joining the tape ends, the joining end of the tape held by the fixed gripper is placed on the anvil of the ultrasonic welding means,
The joining end of the tape held by the moving gripper is overlapped with the joining end placed on the anvil by moving the moving gripper horizontally toward the fixed gripper. At this time, since the fixed gripper and the movable gripper are installed stepwise, the joining ends of the tapes are accurately staggered over the ultrasonic welding means.
Next, the ultrasonic welding means is operated to weld and integrate the joining ends of the tape.

[0005]

However, in the joining technique disclosed in Japanese Patent Publication No. 52-14659, the engaging element at the joining end of one of the surface fastener members is removed to obtain a smooth surface. When superimposed on the joining end of the mating fastener member of the other party and joining, the hook-and-loop fastener members are slippery, the hook-and-loop fastener members are relatively displaced and cannot be joined accurately, and the obtained product is in appearance. Is bad and the commercial value is low.

In the joining technique disclosed in Japanese Utility Model Publication No. 2-46999, the joining end of the tape protruding from the tape held by the movable gripper can be moved when moving toward the fixed gripper. Due to the flexibility, it is not always possible to maintain a horizontal position, and depending on the material, there are many cases where it is impossible to accurately overlap the joining end on the tape side which is sandwiched by the fixed gripper and placed on the anvil. .

Further, in the conventional joining technique of this type including the joining technique disclosed in these publications, the position of the edge in the longitudinal direction of the tape is not considered.
At present, no particular measures have been taken for positioning the side edge position in the tape width direction. Further, for example, in the joining technique disclosed in Japanese Utility Model Publication No. 2-46999, if the transfer speed of the tape after joining and the movement speed of the moving gripper are strictly controlled, the tape protruding from each gripper can be controlled. Although the length of the joining end, that is, the joining margin can be made constant, this not only complicates the structure of the apparatus and the control system, but also increases the cost.

[0008] The joining margin of the tape end by a general tape end joining machine of this type depends on the intuition of the operator, and thus tends to vary among individuals. If the joining margin of the tape end is not constant, the joining strength differs. And it is difficult to secure a certain strength. Also, the widths of the tapes to be joined are not necessarily the same, and even if the tape widths are the same, when the center lines of the tapes do not match and are joined in the width direction, Naturally, not only will the commercial value of the joining tape be lost, but the gap between the tape ends caused by the displacement will likely cause troubles in the subsequent process due to the tape being caught, and the width of the side edge of the tape as in the past. If no special measures have been taken to align the positions, the joining operation is further complicated in order to match the center lines between the tape ends.

The present invention has been made to solve such a conventional problem. Specifically, a simple mechanism does not cause a shift in the center line between the tapes at the time of joining the tape ends. It is an object of the present invention to provide a positioning device for a tape joining end portion in which a joining margin is always uniform and a tape end joining machine equipped with the same.

[0010]

The object is effectively achieved by the present invention according to claims 1 to 7 as described below. The invention according to claim 1 is a positioning device that is applied to a tape edge joining machine that overlaps and joins tape edges, and that positions an edge overlapping position of each tape and a side edge position thereof, wherein the tape edge joining is performed in the middle. A pair of left and right tape guide tables arranged in the longitudinal direction of the tape across the space, and on each tape guide table, extend in parallel along the longitudinal direction of each tape and hold the center line in the tape width direction. It is possible to change the tape side edge contact interval,
First and second side edge positioning means for positioning each tape side edge position; and the tape is disposed orthogonal to the first and second side edge positioning means and parallel to the surface of the tape guide table. The tape end positioning device is configured to be capable of moving back and forth toward the end joining space and comprising edge positioning means for positioning each tape end in the longitudinal direction in a staggered manner.

First, the distance between the first and second side edge positioning means is set to be wider than the width of the tape to be joined, and the edge positioning means is moved to the joining portion of the tape end joining space. Next, the tape ends to be joined between the first and second side edge positioning means provided on a pair of tape guide tables disposed on the left and right with a predetermined joining space are staggered. The tape is introduced from the opposite side of the table, and the joining dimension position of each tape edge is positioned by the edge positioning means.

Subsequently, the distance between the first and second side edge positioning means is reduced, and the tape is brought into contact with the side edge of each tape. At this time, the first and second side edge positioning means arranged on the front and rear tables approach and separate from each other with the same movement amount without changing the center line position. Therefore, the center lines of the left and right tape ends abutting on the first and second side edge positioning means automatically coincide with each other. Thereafter, the tape edge positioning means is retracted from the joining space between the tape guide tables, and the overlapping portions of the tape ends are joined and integrated by an appropriate joining means provided in the space. In the above, the positioning order of the edge overlapping position and the side edge position may be reversed.

According to a second aspect of the present invention, each of the first and second side edge positioning means of the tape side edge includes a pair of support members fixed to a pair of left and right tape guide tables, and And a pair of front and rear tape guide members that move toward and away from the predetermined position toward the side edge of each tape with the same movement distance.

Each of the tape guide members of the first and second side edge positioning means is moved toward and away from the support member so that the center line of the tape side edge contact gap is in an immovable position. Moving. Therefore, even if the tape introduced between the tape guide members on the tape guide table is shifted from the center line of the tape contact interval between the tape guide members to the left or right, even if the center line position is shifted. When the tape guide member is brought into contact with the side edge of the tape while being synchronized and approached, the center line in the width direction of the tape end automatically shifts to the center line of the tape contact interval of the tape guide member. . Therefore, as long as the center lines of the first and second side edge positioning means are on the same straight line, the center lines of the tape end portions before and after the joining are automatically matched.

According to a third aspect of the present invention, each of the support members is attached to one of the left and right ends of the table so as to be rotatable up and down around its attachment end. Is provided with a rotation operation lever. With such a configuration, after the joining of the end portions of the tape is completed, if the rotating operation lever is operated to rotate both support members upward together with the respective positioning means, the open end of the support member and the table can be moved. The tape after joining can be taken out from between.

According to a fourth aspect of the present invention, the edge positioning means for the tape edge is formed of a single member, and the single member is a first and a second tape abutting tape edges in a staggered manner. Tape edge contact surface. Since the relative positions of the first and second tape edge contact surfaces formed on a single member as the edge positioning means do not change, the first and second tape edges are staggered. When the guide member is retracted from the tape edge positioning position after contacting the tape edge contact surface, each tape end overlaps with the tape margin always constant as long as the same guide member is used.

According to a fifth aspect of the present invention, in addition to the above-mentioned structure, before and after the tape guide table is pressed and fixed at the end of each tape to each table in the vicinity of the cape end joining gap of each tape guide table. It has a pair of pressing and fixing means. Before the tape edge locating means retracts from the tape end joining gap of the tape guide table, by operating the pressing and fixing means to press and fix the inside of the joining end of each tape onto the table, This ensures that the subsequent tape end joining operation can be performed.

The invention according to claim 6 is the invention according to claims 1-5.
A tape end joining device for joining tape ends to each other in a tape end joining space between a pair of left and right tape guide tables of the tape end positioning device according to any one of the above. Machine. Further, the tape end joining device is provided with a heat welding means as in the invention according to claim 7.

In the present invention, as the tape end joining device, in addition to the heat welding means, for example, when the tape material is not a heat welding material, a joining means using an adhesive can be adopted. However, in the case of the joining means by the adhesive, in addition to the heating and pressing means of the joining portion of the tape end, since an adhesive applying means and the like are required, when the tape material is a heat welding material, It is preferable to employ a heat welding means as a tape end joining device as much as possible.

However, examples of the heating welding means include a heating bar heated by a heater, an ultrasonic welding machine, and a high frequency welding machine. Among them, as in the invention according to claim 8, it is particularly preferable that the welding device is provided with an ultrasonic welding means for easily controlling a heated portion.

5b '. The pair of rack portions 14a, 14a '; 15a, 15a' inserted into each sliding contact space are engaged with the pinions 16c, 17c, respectively.

On the extension of the tape welding space 3 formed between the pair of left and right tape guide tables 1 and 2, a tape edge positioning means 20, which is one of the components of the present invention, is disposed. Have been. According to the present embodiment, the tape edge positioning means 20 includes a positioning bar member 21 having a required length, and an air for moving the bar member 21 into and out of the tape welding space 3 on the extension line. And the air cylinder 2
2 is fixed on a base (not shown).

The positioning bar member 21 has a substantially S-shaped cross section due to the upper surface of the ultrasonic horn 42, and its bottom surfaces 21a, 21b, which are staggered in the vertical direction and parallel to each other, It is located at a position facing the upper surfaces of the left and right tape guide tables 1 and 2 in the tape welding space 3. Therefore, the left and right tape guide tables 1, 2
Are installed with a required step across the tape welding space 3. The rear end of the positioning bar member 21 and the piston rod 22a of the air cylinder 22 are connected via an L-shaped connecting member 23.

Further, in the present embodiment, the tape fixing means 3 for pressing the end of the tape is provided near the edge facing the welding space 3 between the tape guide tables 1 and 2 which are installed stepwise.
0, 31 are arranged. Each pressing and fixing means 30, 31
Are moved up and down toward the upper surface of each table by the air cylinders 32 and 33, and a pair of left and right pressing and fixing members 34 to press and fix the vicinity of the welding ends of the tapes overlapped during welding.
35. The pressing and fixing members 34 and 35 are formed of plate members extending along the edges of the tape guide tables 1 and 2.

Then, each of the tape guide tables 1, 2
An ultrasonic welding device 40 for welding the end of the tape is disposed in the welding space 3 formed therebetween. In the ultrasonic welding apparatus 40, an anvil 41 is disposed above the welding space 3 and an ultrasonic horn 42 is disposed below the anvil 41. According to the present embodiment, the ultrasonic horn 42 is installed at a fixed position, and the anvil 41 moves toward and away from the ultrasonic horn 42 by an air cylinder (not shown).

Now, in order for the tape ends to be overlapped and welded and integrated by the tape end joining machine according to the present embodiment having the above configuration, first, the first and second tape side edge positioning means 10 and 11 are required. By rotating the operation knobs 16b, 17b, the rack portions 14a, 14 of the first and second tape guide members 14, 15 meshed with the pinions 16c, 17c.
a '; each sliding contact groove 16a, 1 corresponding to 15a, 15a'
6a '; 17a, 17a' are slid in synchronization with each other in the direction of separation. As a result, each pair of centering guides 14
The distance between b, 14b '; 15b, 15b' increases and decreases by the same distance around the pinions 16c, 17c. The enlargement interval at this time is set slightly larger than the width of the tape to be joined.

One tape edge positioning means 20 extends the air cylinder 22 to allow the positioning bar member 21 to enter the welding space 3 and shrink the air cylinders 32, 33 of the pressing and fixing means 30, 31. After a long time, the pressing and fixing members 34 and 35 are moved from the respective tape guide tables 1 and 2 to a standby position above.

In this state, a pair of tape ends are placed on each of the tape guide tables 1 and 2, and as shown in FIG. Until it comes into contact with the bottom surfaces 21a and 21b,
The centering guides 14b, 14b 'and 15b, 15b' are inserted in a staggered manner from the left and right. By causing each tape end to abut on each of the bottom surfaces 21a and 21b of the positioning bar member 21, the overlapping margin of each tape end can be kept constant.

After confirming that the edges of the tapes T1 and T2 have come into contact with the bottom surfaces 21a and 21b of the tape edge positioning means 20, the pinions 16c and 17c are rotated in the opposite direction to rotate the pair of the pinions 16c and 17c. Guides 14b, 14
b '; 15b, 15b' until they contact both side edges along the longitudinal direction of each tape T1, T2 as shown in FIG.
The spacing between the centering guides 14b, 14b '; 15b, 15b' is reduced. At this time, each pair of centering guides 14b,
The middle point of the interval between 14b '; 15b, 15b' does not change even if the interval changes, and the corresponding centering guides 14b, 14b '; 15b, 15b' move at the same moving distance. In order to reduce the distance, the center line position of each tape end portion sandwiched therebetween automatically shifts to the midpoint position, and each centering guide portion 14b, 14b '; 15b, 15
When b 'comes into contact with the front and rear edges of the tape end, the center lines of the opposing tape ends naturally shift to the same straight line.

This means that if the widths of the tapes to be joined are the same, both side edges of the overlapped tape ends automatically match, and if the widths of the tapes to be joined are different. Also, as shown in FIG.
1 means that the center line CL of T2 automatically matches. Therefore, the complicated work of centering the ends of the joining tape, which was conventionally required for each joining, can be easily performed.

After the above operation is completed, the air cylinder 22 is contracted to retract the positioning bar member 21 from the welding space 3 to the outside, and the pressing and fixing means 3
The air cylinders 32 and 33 of 0 and 31 are extended, and the respective tapes are pressed and fixed to the upper surfaces of the tape guide tables 1 and 2 by pressing and fixing members 34 and 35, respectively. When the positioning bar member 21 is retracted outward from the welding space 3, the left and right tape guide tables 1 are held in a state where the tape ends that have been staggered by the positioning bar member 21 are overlapped. , 2 is mounted on the upper surface of the ultrasonic horn 42 installed in the welding space 3 and does not hang down in the welding space 3.

Next, the anvil 41 waiting above
Is lowered, and the tape end overlapped as described above is sandwiched between the ultrasonic horn 42 and the ultrasonic horn 42 is operated to weld and integrate the tape end.

FIG. 7 shows a second embodiment of the present invention. As can be understood from FIG. 7, in this embodiment, a pair of left and right support members 1 of the tape side edge positioning means 10 and 11 are provided.
Rather than being fixedly mounted on each of the tape guide tables 1 and 2, the short pieces 1
2a and 13a are pivotally supported, are rotatable up and down with respect to the tape guide tables 1 and 2 around the pivots, and the support members 12 and 13 are connected by the operation lever 6.

With this configuration, in this embodiment, after the tape ends are welded and integrated as described above, the operation lever 6 is rotated rearward as indicated by the arrow in FIG. As a result, the first and second tape guide members 14 and 15 rotate upward together with the support blocks 16 and 17 fixed on the support members 12 and 13, respectively, and the tapes whose ends are welded and integrated. T1 and T2 can be easily taken out from the tape joining machine.

FIG. 8 shows the tape side edge positioning means 10,
11 shows a modification of the first and second tape guide members 14 and 15 of FIG. According to this modification, comb-shaped sliding guide members 14d, 14d '; 15d, 15d' are attached to the respective upper surfaces of the centering guide portions 14b, 14b '; 15b, 15b' by meshing with each other. . The sliding guide members 14d, 14d '; 15d, 15d' keep the centering guide portions 14b, 14b '; 15b, 15b' parallel to each other, and accurately expand and contract the distance therebetween. Of course, the comb-shaped sliding guide members 14d, 14
d '; 15d, 15d' instead of the tape guide tables 1, 2 and the centering guides 14b, 14b ';
15b ', the centering guides 14b, 1
4b '; a ridge extending in the moving direction of 15b, 15b';
A sliding guide groove which can be slidably fitted to the ridge can be provided.

As can be understood from the above description, according to the tape end positioning device and the tape end joining machine of the present invention, the center position of the tape end is automatically set when the tape ends are overlapped and joined together. Can be matched, and the overlapping dimension between the tape ends can be kept constant. This eliminates the need for complicated work of aligning the tape ends and keeping the overlapping allowance constant, and in addition, The difference can be eliminated. Furthermore, since the tape ends are always supported by the constituent members of the apparatus of the present invention in any of the joining preparation step and the joining step of each tape end, even if the tape is thin and flexible. However, the end portions can be securely joined to each other.

The above embodiments are merely typical examples of the present invention, and the present invention is not limited to these embodiments. For example, in the above embodiments, an ultrasonic welding device is used as a joining device. However, it is also possible to use a high-frequency welding device or a heating welding device using a heat bar instead of the ultrasonic welding device, and if the tape material does not have a heat welding property, an adhesive may be used. It is also possible to use the usual bonding equipment for bonding according to. In the above embodiment, the centering of the tape is performed by manual operation. However, instead of the operation knobs 16b and 17b, the pinion can be directly rotated using a direct electric motor or the like. The center of the tape ends can be aligned by a simple switch operation. Others
Various design changes are possible within the scope of the technical idea of the present invention.
