Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to a rod-shaped body (hereinafter referred to as a strand) of a raw material such as a candy that can be plastically deformed is conveyed at a constant speed, and a unit piece is cut from this strand by a cutter. An apparatus for cutting a unit piece of a predetermined length from a raw material strand to be cut.

(Prior Art) Apparatuses for cutting unit pieces from raw material strands such as soft and plastically deformable candy are already known.

There are roughly two methods for cutting a unit piece having a predetermined length from such a raw material strand.
The first method is to continuously feed the strands and perform the cutting without stopping the movement of the feeding of the strands. The second method is a method in which the strand is cut during the cutting so that the strand is cut.

(Problems to be solved by the invention) However, in the first conventional method for cutting a raw material strand, since the strand is continuously supplied during the cutting of the strand, the cut surface of the strand pushes the blade of the cutter for cutting. In some cases, the cut surface may be distorted due to friction with the cutter. In addition, it is unavoidable that the cut surface is not perpendicular to the longitudinal direction of the strand.

Further, in the above method, it is necessary to limit the supply rate of the strand in relation to the time required for cutting, and as a result, there is a problem that the strand cannot be supplied at a high speed and the work efficiency is low.

Next, the second conventional method for cutting a raw material strand has a problem that the raw material strand has to be intermittently supplied although the cut surface has a good finish. It goes without saying that such intermittent supply of raw materials reduces the cutting work efficiency.

Therefore, the object of the present invention is to solve the problems of the above-mentioned conventional techniques, while continuously supplying the raw material strands at a high speed,
An object is to supply a device for cutting raw material strands into unit pieces of a predetermined length at right angles to the feed direction and cleanly.

(Means for Solving the Problems) According to the present invention, the grooved cam is fixed to the shaft fixed to the casing by being inclined with respect to the strand conveying gutter, and the grooved cam is arranged on the shaft. A cutter is attached to at least one cutter holder that is surrounded by a cutter-holding cylindrical plate that is rotatably supported, and that is swingably supported on the outer periphery of this cutter-holding cylindrical plate. This is achieved by mounting on the holding body a lever with a cam roller which cooperates with the cam track of the grooved cam.

Embodiments The present invention will be described in detail below with reference to the embodiments shown in the drawings.

As shown in FIGS. 1 and 2, this apparatus has strand conveying wheels 2 and 3 and a strand conveying trough 1 that supports the strand conveying wheels 2 and 3. In the casing 4 below the strand transport gutter 1, a shaft 5 that is inclined with respect to the strand transport gutter 1 is fixed. The shaft 5 is fixed so as not to rotate, and the grooved cam 7 is firmly attached to the shaft 5.
A cutter holding cylindrical plate 6 which is rotatable with respect to the shaft 5 is attached to the outer periphery of the shaft 5. A cutter holder 8 is swingably attached to the outer periphery of the cylindrical portion of the cutter holding cylindrical plate 6. A cutter 9 is fixed to the cutter holder 8. The cutter holder 8 is provided with a lever 10 with a cam roller 11 that acts in cooperation with the cam track of the grooved cam 7 inside the cutter holding cylindrical plate 6. The drive element 12 of the cutter holding cylindrical plate 6 is connected to the inside of the casing 4.

The device configured as described above operates as follows.

After being formed by a strand forming apparatus (not shown), the strand S is guided by the strand conveying gutter 1 and conveyed by the strand conveying wheels 2 and 3 to the cutting region in the arrow direction in the figure. In this cutting region, the cutter holding cylindrical plate 6 is rotating, and the cutter 9 attached to the outer peripheral surface of the cutter holding cylindrical plate 6 as the cutter holding cylindrical plate 6 rotates.
Cuts across the strand S. In this case, the cutter holding cylindrical plate 6 is attached so as to be inclined with respect to the strand S, and due to this inclination, the cutter 9 cuts this while moving in the supply direction of the strand S in the cutting process. This makes it possible to obtain a cut surface that is substantially perpendicular to the longitudinal direction of the strand S.

In this device, the cutter 9 cuts the strand S in contact with the outlet of the strand conveying gutter 1 at the beginning of cutting, so it suffices to hold the cutter 9 so as to be orthogonal to the strand S. Since the location is separated from the outlet of the strand transport gutter 1, the blade of the cutter 9 must be rotated so as to face the supply direction of the strand S. Therefore, in this apparatus, the cutter holding body 8 is configured to engage with the groove of the grooved cam 7 via the lever 10 inside the cutter holding cylindrical plate 6. As shown in FIG. 1, the groove of the grooved cam 7 causes the lever 10 to rotate clockwise around the pivot point as the cutter holding cylindrical plate 6 rotates. By the action of the lever 10 and the grooved cam 7, the blade of the cutter 9 rotates so as to face the supply direction of the strand S depending on the cutting position.

FIG. 2 shows the positional relationship between the strand S and the cutter 9. As shown in the figure, the cutter 9 cuts the strand S from below. As described above, the cutter 9
Since the blade rotates during cutting, its cutting edge is curved in an arc shape as shown in the drawing. The curved shape of the cutting edge of the cutter 9 depends on the distance from the rotation center of the cutter 9, and is determined by the physical properties of the strand S, the rotation speed of the cutter 9, and the like.

As described above, according to this apparatus, the cutting position of the cutter 9 moves according to the supply of the strand S, so that the cutter 9 is not pressed by the supply of the strand S during cutting as in the conventional method, and the high quality is achieved. Strand S at the cut surface
Can be cut vertically.

Further, in the present device, since it is not necessary to stop the supply of the strand S during cutting, and the cutter 9 is not interfered with by the supply of the strand S, the unit piece having a predetermined length while continuously supplying the strand S at a high speed. Can be cut.

The length of the unit piece to be cut is determined by the attachment interval of the cutter 9. FIG. 2 shows an example in which two cutters 9 are attached to the outer peripheral surface of the cutter holding cylindrical plate 6, but by increasing the number of cutters 9, it is possible to cut unit pieces of short length, In the opposite case, long unit pieces can be cut.

〔The invention's effect〕

As is clear from the above description, according to the present invention, while continuously supplying the plastically deformable raw material strand at high speed,
It is possible to obtain an apparatus for cutting a raw material strand into a unit piece having a high cut surface quality and efficiently cutting into a unit piece having a predetermined length.
