The material is guided to S, and is pulled out downward through the space provided between the cylindrical body 18 and the outer cylindrical body 1a of the supply cylinder 1 at this turning point. The tape-like material is formed into the cylindrical body 21 by welding the ears 2a together through the welding means 3 facing the meeting position.

The feed roller 4 draws out the tape-shaped material 2 toward the supply tube 1, and rotates on the peripheral surface of the tube to feed the material formed on the tube body 21 to a welding and fusing means provided below.

, and the fusing indenter 7 and pressure receiver 8 constituting the welding and fusing means of a82 are on the same horizontal plane, and the first welding and fusing means is in contact with the extension line of the supply tube l from the front and back direction, and the second welding and fusing means is The fusing means face each other from the left and right directions and are opposed to each other at different angles of 901'. These two sets of indenters are configured to perform pinching movements alternately at time intervals.

Fig. 4 shows the first welding and fusing means facing each other in the front and back, and Figs. The second welding and fusing means, which will be described in detail with reference to the drawings, has the same configuration as the first means, so the description thereof will be omitted here.

Now, as shown in the figure, the fusing indenter 5 and the indenter 6 are fixed to each tip of a horizontally extending support arm 22.23 and are arranged opposite each other. It is supported by a swinging support rod 24.25 pivotally connected to the rear end and a crank mechanism 26.27 connected to the rear end.

The swinging support rods 24.25 have their lower ends 28.29 rotatably supported on the basic frame of the device (not shown) and stand upright, and their upper ends are connected to the support arms 22, 23 via pins 30.31.

In addition, the crank mechanism 28.27 has a rotating shaft 32.33 at one end.
Rotate in the direction of the arrow.

A pin 34.35 provided at the rotating end is attached to the support arm 22.23.
The support arm is supported by being pivoted to each rear end of the support arm. Although not shown, both the rotating shafts 32 and 33 are connected to rotate at a constant speed.

The fusing indenter 5 works with the opposing indenter 6 to press the cylindrical body 2.
1, and is equipped with a fusing blade 5a powered by high-frequency current at the tip, and a cover 38 that covers this fusing blade.
Equipped with This fusing indenter 5 has a wide and thick plate shape,
The tip is sharpened and formed into a rectangular shape, and a fusing blade 5a is provided over the entire width at the tip of this rectangle. And cover 3B
The indenter 5 is formed into a box shape that encloses the entire indenter 5, and is mounted so as to be able to slide freely back and forth, and is always urged forward by a spring 38 that is compressed between the indenter and the supporting base 37 of the indenter.

The fusing blade 5a is made to retreat inward of the cover 36 by pushing forward the ejection opening 33 that opens in a horizontal line at the tip. The tip of this cover 36 is tapered,
A horizontally long ejection opening 38 is provided at this narrowed end portion, and the ejection opening 3B is formed in a size that allows the fusing blade 5a to protrude.

The fusing indenter 5 is formed with a cone that can compress the entire flattened cylinder 21 when the cylinder 21 is pressed, as will be described later. The receiving indenter 6 facing the fusing indenter 5 has a sharp tip to enable linear clamping, and is formed wide to match the width of the fusing indenter 5.

The fusing indenter 5 and the indenter 6 are actuated by the rotation of the rotating shaft 32.33 and the rotation of the crank mechanism 28.27 in the direction of the arrow, and the cylindrical body 21 is sent out through the supply cylinder l.
is compressed and flattened horizontally in a straight line, then welded and cut. As mentioned above, both rotating shafts 32 and 33 rotate at a constant speed, and when the crank mechanism rotates in the direction of the arrow, the support arm 22.23 pivotally attached to the pin 34.35 moves to the swinging support rod 24.25. The fusing indenter 5 and the indenter 6, which are fixed to their respective tips, rotate in the opposite direction to the crank mechanism 28, 27, and perform an elliptical rotational movement, and both jointly rotate the cylinder. The body 21 is pinched, and this pinched portion is sent out downward in a pinched state.

FIG. 10 shows that the internal indenter 5 is rotated by the rotation of this crank mechanism.
．． 6 is an illustration of the relationship between elliptical movement and squeezing, where A indicates the locus of the pin 34 of the crank mechanism, and B indicates the trajectory of the support arm 22.
, C indicates the swinging support rod 24°, D indicates the fusing indenter, and positive values indicate the trails of the fusing blade 5a. As shown here, when the support arm 22 is swung back and forth by the rotation of the pin 34, the fusing blade 5a rotates along an ellipse due to the action of the swing support rod 24, and extends below the supply cylinder l. It approaches the extension line 40 while moving from above to below, then moves away from below while moving upward, and by repeating this repeatedly, the cylindrical body 21 is crushed and sent out.

Figure 8 shows the state in which the fusing indenter 5 and pressure receiving element 6 begin to press the cylindrical body 21 sent out from the supply cylinder 1 due to the above-mentioned interlocking action, and Figure 9 shows a state in which the rotation progresses and the cylindrical body 21 is compressed. It shows. When the indenters 5 and 6 collide with each other, the cover 38 covering the fusing indenter 5 compresses the spring 38 due to the collision with the indenter 6 and retreats, and its protruding opening 39
The fusing blade 5a is made to protrude from the top and collide with the pressure receiving element. Therefore, due to the collision of the internal indenters, the cylinder body 21 is crushed horizontally in the middle of its length and is welded by the fusing blade 5a to partition the inside of the cylinder. (As described in S, this part will become a tea pack.) and the remaining cylindrical body 21 will be closed at the cutting location.

The device according to the present invention operates the measuring device 9 to discharge a predetermined amount of contents from the recess 12 into the supply tube l when the cylinder body 21 is welded and fused by the operation of the first welding and fusion cutting means. , and put it through this tube into a tube body 21 whose lower end is closed. Of course, this charging of the contents is carried out in parallel while the fusing indenter 5 and the indenter are making elliptical movements. And an internal indenter 5.
When the internal indenter 5.6 separates and retreats from directly below the supply cylinder, the process is completed, and while the internal indenter 5.6 separates and retreats, the second
The fusing indenter 7 and the indenter 8 having the same configuration are advanced directly below the supply cylinder l from the left and right directions, and the cylinder body 21 is similarly compressed, and the fusing blade provided in the fusing indenter 7 is used to force the fusing indenter 7 and the pressure receiving element 8 to move in a horizontal line. Cylindrical body 21 crushed flat to form a shape
Welding and simultaneously cutting at this welding position,
By this cutting, a triangular pyramid-shaped tea bag 41 is obtained.

The second welding and cutting means facing from the left and right can automatically form a triangular pyramidal tea bag because the indenter facing opposite to the first welding and cutting means is oriented 90' differently. .

When the cutting of the cylinder 21 by this welding and fusing means is completed, the contents are dropped from the measuring device 9 again, and then the fusing indenter 5 and pressure receiving element 6 of the first welding and fusing means are placed directly below the supply cylinder l in the front and rear direction. The next tea bag 41 is cut off by pushing it out, crushing it horizontally in a straight line, welding it, and cutting it by melting.

In this manner, the apparatus of the present invention forms the cylinder 21 from the tape-shaped material 2 supplied on the circumferential surface of the supply cylinder l, and simultaneously feeds the formed cylinder downward. The triangular pyramid-shaped tea bags 41 can be continuously manufactured by alternately operating the second welding and fusing means and dropping the contents intermittently through the supply tube 1 during this period. A device for guiding the cylindrical body 21 into a flat shape when compressed by the indenter 5.degree. 6 of the welding and fusing means is built-in.

11 to 6 illustrate the means for guiding this cylindrical body into a flat shape. In the figures, reference numeral 42 and 42 are expansion pieces, and 43 is an operating rod for moving the expansion pieces in and out.

The expansion piece 42 extends between the inner and outer cylindrical bodies la, l that constitute the supply cylinder l.
It is housed in the gap formed by b, and is housed in symmetrical positions across the center line of the supply cylinder so as to be able to freely slide along the vertical direction. This expansion piece 42 is formed from a narrow band-shaped spring piece, and each lower end portion is shaped to expand outward from the middle of the length, and the outer surface of the lower part 111i A sliding protrusion 44 is provided.

The operating rod 43 has a semicircular arm 45 at its tip, and a pin 47 protruding from the upper end of each extension piece 42 is slidably connected to a cutout 4B provided at the tip of this arm. is fixed to a rotating shaft 48 supported on a fixed frame (not shown), so that the tip can swing up and down about the rotating shaft as a fulcrum. As shown in FIG. 4, a swinging arm 49 is installed rearwardly extending from the rotating shaft 48, and while the rear end of this arm is pulled downward by a lever 50, the swinging arm 49 The cam plate 51 is slid onto the cam plate 51 from below in the middle of the length. The cam plate 51 rotates around a shaft 52, and a pulley 53 provided on this shaft 52
A belt 55 is stretched between the cam plate 51 and a pulley 54 provided on the rotating shaft 32 of the crank mechanism, so that the cam plate 51 and the first welding and fusing are synchronized.

Figures 4 and 11 and 12 show the indenters 5 and 6 of the first welding and fusing means sandwiching the cylinder 21 from the front and back to perform welding and fusing. At this time, the cam plate 51 The spring 50 is extended so as to face the swinging arm 49, and the tip of the operating rod 43 is pushed down using the rotating shaft 48 as a fulcrum.

Pushing down the tip of the operating rod 43 lowers the left and right expansion pieces 42, 42 connected thereto, and the lower ends of both expansion pieces 42 protruding from the lower end of the supply cylinder l are inserted into the gap between the inner and outer cylinders. The cylinder 21, which expands to both sides as it comes out and is fed out downward using the outer circumferential surface of the supply cylinder as a guide, expands in the left-right direction, and the cylinder is shaped into a flat front-to-rear shape in this portion.

As mentioned above, the lowering of the expansion piece 42 and the front and rear indenters 5.
Since the clamping operations 6 are set to be interlocked, the expanding piece begins to descend, thereby expanding the cylindrical body 21 into a flat shape, and at the same time, the front indenter 56 begins to approach. Then, when the expansion piece 42 reaches the lowest point, the welding and fusing by the fusing indenter 5 and the receiving indenter 6 are completed, and the triangular pyramid-shaped tea bag 41 is separated from the lower end of the cylindrical body 21.

In the illustrated embodiment, the expansion pieces 42 are provided in pairs on the left and right, so that the expansion operation for the cylinder 21 is performed only during the first welding and cutting, but another pair may be provided in the front and rear. Of course, the structure may be such that it is activated during the second welding or fusing to expand the cylindrical body in the front-rear direction. In this embodiment, the cylindrical body 21 is placed with the indenters 7 and 8 facing from the left and right directions.
When crushing the cylinder into a flat shape, the vertical welded part 2a (the joined ears) provided on this cylinder acts as a guide line for the folding dent and guides the flattening, so the crushing position may be distorted. The second expansion means is omitted because there is almost no possibility of distortion or distortion.

When the clamping operation by the first welding/cutting means is completed and the inner depressor 5.6 starts to retreat, the swinging arm 48 is released from being pushed up by the cam plate 51, and both the expansion pieces 4
2.42 is pulled up (see Figure 13), and the lower end part that spreads outward retreats into the gap of the supply cylinder, returning the cylinder body 21 to its original state and being pinched from the left and right by the primary and second welding and fusing means. You will be prepared for the installation.

In the figure, 5B is a belt conveyor for carrying out tea bags provided below the supply tube l, and the produced and melted tea bags 41 fall one after another onto this conveyor and are taken out of the apparatus.

〔Effect of the invention〕

The embodiments illustrating the present invention have been described in detail above, but according to the present invention, a cylindrical body is formed from a tape-shaped copper material, this cylindrical body is crushed into a flat shape, welded, and simultaneously cut by fusing. During this time, the contents are filled and the cylinder is continuously fed out, and then the same operation using the second welding and fusing means is repeated, and this process is repeated alternately to produce a triangular pyramid-shaped tea bag. During this time, all processes of supplying materials, forming the cylinder, adding contents, forming and cutting the tea bags can be manufactured in continuous operation without stopping, which has the advantage of excellent productivity and mass production. .

In particular, the present invention alternately operates two sets of welding and fusing means installed on the same plane to flatly weld and fuse the cylindrical body, and at the same time, indenters of both means are moved along a circular or elliptical shape. Since it is configured to rotate along a trajectory, the flow of production does not stop when cutting the tea bag, allowing continuous production, and the indenter that cuts the tea bag recedes horizontally to prevent the tea bag from falling. Since it does not interfere with the process, there is no contact with the fusing blade at the tip of the fusing indenter, and the risk of producing defective products is extremely low.

In addition, the present invention expands the cylindrical body with the expansion piece before being crushed by the indenter of the welding and fusing means to ensure guidance of the crushing position. This has the advantage of effectively preventing the tea bag from becoming shaped like a triangular pyramid due to strain or other distortions in the cylinder.

The fusing blade is fixedly attached to the tip of the support arm, while the cover uses a spring that is compressed between the cover and the support arm so that the protruding opening at the tip always protrudes forward from the cutting edge of the fusing blade so that it collides with the pressure receiver. 1. An apparatus for producing a triangular pyramidal tea bag, characterized in that the tip of the cover is pressed to expose a fusing blade from the ejection opening. (5) a supply cylinder which is installed vertically and guides the contents to fall through the hollow interior and which is wound with a tape-like mesh material to be supplied along the longitudinal direction on the circumferential surface and shaped into a cylinder; a welding means that is arranged opposite to the circumferential surface and aligns both ears of the tape-like mesh material to be wound and simultaneously joins them together to form a cylinder shape; a feeding means, a fusing indenter and a pressure receiving element which are disposed below the supply tube and horizontally opposite to each other across an extension line of the feed tube; The first welding and fusing means is located on the same horizontal plane as the first welding and fusing means, and the fusing indenter and the receiving indenter are arranged in an intersecting manner to push the cylinder body horizontally in a straight line from 90 degrees different directions. and a second welding and cutting means for crushing and welding and cutting, and each of the first and second welding and cutting means moves each fusing indenter and receiving indenter into a circular or elliptical trajectory through a swinging support mechanism. a triangular shape that is supported so as to rotate along the feed cylinder, and is fed from above to below in accordance with the movement of horizontally pinching the cylindrical body fed out from the supply tube, and the welding and cutting is synchronized with the feeding speed of the cylindrical body; In the cone-shaped tea bag manufacturing apparatus, a pair of spring-made extension pieces are slidably fitted to opposing walls of the supply cylinder across the center line along the axis of the cylinder. A triangular pyramidal tee is configured such that the distal end of the expanding piece protrudes from the lower end opening of the supply cylinder in synchronization with the unwinding of the cylinder and prior to crushing by the welding/fusion cutting means, thereby expanding the unrolled cylinder in two directions.
