DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous type cracker, for example, a double continuous type or a triple continuous type cracker.

[Conventional technology]

Conventionally, a partition plate has been provided in the center of the inside of the cracker cylinder, and the inner space of the cylinder partitioned by this partition plate is loaded with two paper powders that are exploded by pulling the drawstring.
A two-shot cracker disclosed in Japanese Patent No. 716 is known.

[Problems to be solved by the device]

In the conventional two-shot cracker, two drawstrings that explode two paper powders extend outwardly from a string hole at the rear end of the tubular body, and the two drawstrings are pulled one by one to obtain 2 Since two explosive bodies are sounded (exploded) one by one, the two drawstrings that extend from the rear end of the cylinder toward each other must be separated and operated separately. No
There is also a problem that the operation is troublesome and difficult to use, and when two pulling cords are simultaneously pulled, two cigarette powders explode at the same time.

In order to solve such a problem, the applicant of the present invention has devised a continuous cracker in which a continuous pulling ball of a single pulling string is loaded inside the cracker cylinder, and has been applied as a prior application of the Japanese Patent Application No. 63-130423. is doing.

The continuous cracker of the invention of this prior application is composed of a plurality of paper powder powder bodies 11, which explode on one drawstring 10 due to the pull-out frictional force of the drawstring,
A continuous pulling ball 9 as shown in FIG. 2 in which 12 are provided at a predetermined interval is provided, and inside the cracker cylinder 1 into which the continuous pulling ball 9 is loaded, the first shot located on the pull string pulling side of the continuous pulling ball 9. The spacer 3 for supporting the cigarette powder body 11 of the above so as not to move in the pulling cord pulling direction is fitted, and the pulling cord 10 of the pulling cord 10 is passed through the seat hole 3a of the spacer 3 and the rear end cord outlet 1a of the cracker cylinder 1. Tensile operation part 10
a is extended to the outside of the cylinder, and the second cigarette powder 12 or a subsequent cigarette powder (not shown) is placed in the cylinder inner space 5 partitioned by the spacer 3. , The drawstring 10
When the pulling operation portion 10a of the above is pulled rearward of the cylindrical body, a plurality of paper-powder powder bodies 11 and 12 are sequentially struck by the handling action of the spacer body 3. A cigarette powder body (not shown) is vertically mounted in the cylindrical hollow space 5.

By the way, the continuous pulling ball 9 loaded in the cracker cylinder 1 is one pulling string 10 provided with a plurality of cigarette powder bodies 11 and 12 explosive by the pulling frictional force of the pulling string at predetermined intervals. , Between the center of the wrapping paper of the explosive bodies 11, 12 and the drawstring 10,
A gap G formed by the encapsulating powder a is formed as shown in FIG.

If the gap G is closed with a coating material or the like, a strong force is required for pulling the drawstring 10 or the pulling operation of the drawstring 10 cannot be performed at all (a misfire problem occurs). Cannot be covered with a coating or the like. Therefore, when the first paper-powder powder body 11 is exploded by pulling the drawstring 10, the flame B and the spark C heading toward the opening of the cylinder.
From the gap G into the vertically-applied explosive body 12 to ignite and explode the encapsulated powder a of the explosive body 12, that is, the first paper-powder body 11 and the second paper-wrap. There is a problem that the explosive body 12 explodes at the same time. Further, since the explosive bodies 11 and 12 are present on a straight line with the drawstring 10 as an axis, the flame B and the spark C are encapsulated in the explosive body 12. Even if it does not enter the part, this explosive body 12
It moves by receiving 11 explosive energy, its gunpowder a and drawstring
There is also the problem of simultaneous explosion due to sliding friction with 10.

This invention has been devised to solve the problems of the above-mentioned prior invention, and its purpose is to improve the structure of the explosive body mounting mechanism so as to prevent simultaneous explosion of the explosive body, and It is an object of the present invention to provide a continuous cracker that can be surely exploded one by one by the stepwise pulling operation of one drawstring.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the continuous cracker of the present invention has a pull cord 10 of a continuous pulling ball 9 provided with a plurality of paper powder powder bodies 11, 12, 12a, and a pull cord 10 of an appropriate hardness that bends. That is, inside the cracker cylinder 1 into which the continuous pulling balls 9 are loaded, the first paper powder 11 located on the pulling cord pulling side of the continuous pulling balls 9 is vertically oriented so as not to move in the pulling line pulling direction. The spacer 3 which is supported by the
10a is extended to the outside of the cylinder through the seat hole 3a of the spacer 3 and the rear end cord outlet 1a of the cracker cylinder 1 in the same manner as in the prior application, and the cylinder partitioned by the spacer 3 A second set of paper powder powder 12 or a subsequent paper powder powder 12a is bent in a meandering manner in the inner empty chamber 5 to set a sideways set state by using the bending habit of the wire cord 10. When the first paper-powder powder body 11 is exploded by a pulling operation, its flame and sparks are prevented from invading the encased powder powder portion of the other device-loaded powder powder 12, 12a. It is a thing.

[Action]

The continuous fire cracker with the above-mentioned structure is the second cigarette powder 12
Alternatively, since the subsequent paper powder material 12a is set in a sideways set state by utilizing the bending tendency of the drawstring 10 bent in a meandering shape, the central gap portion G of the powder materials 12, 12a (the center of the paper wrapper) A gap formed by the encapsulated explosive a formed between the drawstring 10) opens in a direction intersecting with the injection direction of the flame B and the spark C (see FIG. 2) generated when the explosive body 11 explodes, Therefore, the flame B and the spark C from the gap G are prevented from entering the encapsulant a, and the explosive bodies 12, 12a are prevented.
Simultaneous explosion due to the flame ignition of the fire does not occur.

Further, the drawstring 10 is bent in a meandering shape in the inner cavity 5 of the cracker cylinder 1, and the explosive body is bent due to its own bending habit.
Since 12 and 12a are held in a laterally set state, the explosive energy of the explosive body 11 causes the explosive bodies 12 and 12 to be set sideways.
Even when acting on a, the explosive bodies 12 and 12a can only be subjected to a force in a sliding direction with respect to the drawstring 10 only by moving the position in a direction of extending the drawstring curved portions 10b and 10c having a shocking property. Absent. Therefore, simultaneous explosion due to sliding friction between the drawstring 10 of the explosive bodies 12 and 12a and the enclosed explosive a does not occur. In this way, by setting the explosive bodies 12, 12a in a sideways set state in which the drawstring 10 is bent, the simultaneous explosive phenomenon, which is the problem of the prior invention, is eliminated, and a plurality of paper powder bodies 11, 12,
It is possible to surely explode each 12a one by one by pulling the pull string 10 step by step.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. This embodiment shows a three-shot type cracker in which a continuous pulling ball 9 is loaded inside a cracker cylinder body 1. The continuous pulling ball 9 is a piece made of a paper string or the like having an appropriate hardness with a bending tendency. The drawstring 10 is provided with three paper-powder powder bodies 11, 12, 12a that explode due to the pulling frictional force of the drawstring 10 at predetermined intervals.
Between the center of the paper wrapper of each of the explosive bodies 11, 12, 12a and the drawstring 10, there is formed a central gap portion G formed by the encased explosive a as in FIG.

The cracker cylinder 1 has a string hole 1a at the rear end, and the front end opening is in the shape of a cone closed by the explosion release cover 2 of the lightweight foam packing. Inside the cracker cylinder 1, A spacer 3 is fitted to vertically support the first shot paper powder body 11 located on the pulling string pulling side of the continuous pulling ball 9 so as not to move in the pulling string pulling direction. The pulling operation portion 10a of the drawstring 10 extends to the outside of the cylinder through the seat hole 3a of the spacer 3 and the rear end string extraction hole 1a of the cracker cylinder 1 as in the prior application.

The second and the third paper-powder powder bodies are provided in the cylindrical inner space 5 between the spacer 3 and the pressure receiving plate 4 which are partitioned by the spacer 3.
12 and 12a are set in a sideways set state by utilizing the folding habit of the drawstring 10 bent in a meandering shape, and when the pulling operation of the drawstring 10 causes the first explosive powder body 11 to explode, The flame B and the spark C (see FIG. 2) do not enter the enclosed explosive portion of the explosive bodies 12, 12a through the gap G.

In the chamber 6 formed between the pressure receiving plate 4 and the explosion releasing lid 2, when the first cigarette powder body 11 is exploded, the pressure receiving plate 4 and the explosion releasing lid 2 are fired in the air. The ejected material 7 such as a small tape is stored.

The three-shot cracker with the above-mentioned structure is the second cigarette powder body.

It opens in the direction that intersects the injection direction of. Therefore, the flame B and the spark C from the gap G are prevented from invading the enclosed powder a portion, so that the explosive bodies 12, 12a do not simultaneously explode due to the flame spark ignition.

Further, the drawstring 10 is bent in a meandering shape in the inner cavity 5 of the cracker cylinder 1, and the explosive body is bent due to its own bending habit.
Since 12 and 12a are held in a laterally set state, the explosive energy of the explosive body 11 causes the explosive bodies 12 and 12 to be set sideways.
Even when acting on a, the explosive bodies 12 and 12a can only be subjected to a force in a sliding direction with respect to the drawstring 10 only by moving the position in a direction of extending the drawstring curved portions 10b and 10c having a shocking property. Absent. Therefore, simultaneous explosion due to sliding friction between the drawstring 10 of the explosive bodies 12 and 12a and the enclosed explosive a does not occur. In this way, by setting the explosive bodies 12, 12a in a sideways set state in which the drawstring 10 is bent, the simultaneous explosive phenomenon, which is the problem of the prior invention, is eliminated, and a plurality of paper powder bodies 11, 12,
It is possible to surely explode each 12a one by one by pulling the pull string 10 step by step.

In addition, although the above-mentioned embodiment explained the three-shot type cracker, the present invention is applied to the two-shot type cracker in which one drawstring 10 is provided with two paper-powder powder bodies 11 and 12 and the drawball 9 is loaded. However, the same effect as the above can be obtained.

[Effect of device]

Since the continuous cracker of the present invention adopts the above-described explosive body mounting structure, it solves the simultaneous explosion problem of the explosive body, which is the problem of the prior invention, and it is possible to use a plurality of paper powder There are excellent practical effects such as the ability to surely explode one by one by the stepwise pulling operation of the drawstring.
