Description

[Detailed Description of the Invention] The present invention relates to a fixed length cutting device for linear bodies such as dried noodles, and an object of the present invention is to provide a cutting device that has almost no dimensional error between a large number of cut linear bodies.

As shown in FIG. 1, a conventional cutting device of this type has a plurality of rotary cutters 1 installed at predetermined intervals, a feed drum 3 mounted parallel to the cutter shaft 2, and a support suspended horizontally on the feed drum 3. The rod 4 has a gripping frame 5 disposed between the cutters 1, and the gripping frame 5 has a seat plate 6 formed of an arc concentric with the feed drum 3, and a gripping frame 5 arranged in the front and rear in the rotational direction on both sides in the axial direction. It consisted of a hook 7 bent inward.

In this case, since the bottom plate 6 is curved, when the feed drum 3 is rotated to feed the linear bodies 8 in the gripping frame 5 to the cutter 1, they are simply held down by the chain 10, so they are arranged irregularly on the bottom plate 6. The cut linear body 8 is approximately 5 cm per 25 cm.
It had an error of about 10 mm.

Therefore, there has been a problem in that elongated objects can get caught in the heat-sealed part during plastic packaging.

The fixed-length cutting device for a linear body of this invention eliminates the above-mentioned drawbacks of the conventional example, and the invention will be described below with reference to the drawings with reference to one embodiment.

In FIG. 2, the rotary cutter 1 rotates in the direction of arrow 11.

Next, the unit of the feeding mechanism for the linear body 8 will be explained.
The rotation axis 1 is parallel to the cutter axis 2 of the rotary cutter 1.
2 is installed, and a support 13 is erected on the rotating shaft 12.

At the upper end of the pillar 13 is a housing section 14 having a U-shaped cross section.
is installed between the rotary cutters 1 with openings 15 directed outward from the center of the rotary cutters 1.

Further, a shaft 16 is rotatably mounted in the middle of the support column 13 in parallel with the cutter shaft 2, and a pair of left and right L are connected to both ends of the shaft 16 via arms 17 extending perpendicularly to the shaft 16. A letter-shaped pressure feeding section 18 is fixedly provided.

The bottom part 19 of the above-mentioned C-shaped pressure feeding part 18
The rising part 20 forms an arc on the circumference with the radius of the arm 17 and slides along both sides of the bottom of the accommodating part 14 so as to always maintain almost the same plane as the bottom of the front surface of the opening 15 of the housing part 14. It has a length extending above and below the opening 15 of the accommodating portion 14 .

This rising portion 20 is fitted into notches 21 formed on both sides of the upper surface of the housing portion 14 when the linear body 8 is being fed under pressure.

It is preferable that the rising portion 20 is made of an elastic material such as elastic plastic in order to prevent defects such as breakage when cutting the linear body 8, especially noodles. With a piece, attach the tip to 1
A cylinder 22 attached to the bottom 19 of the letter-shaped pumping section 18 is fixed.

Since this hanging piece 23 rotates together with the support column 13, the linear-shaped pumping section 18 opens and closes the housing section 14 on its upper surface due to the expansion and contraction of the cylinder 22.

Further, 27 is a flange provided on the rotating shaft 12.
A transverse feed rod 25 protruding from a piston 24 of a cylinder (not shown) installed parallel to the cylinder (not shown) is engaged, and the column 13 is moved in the left-right direction by the action of the cylinder.

Further, 26 is a transverse lever that engages with the hanging piece 23 and moves the column 13 in conjunction with the transverse column 25, and 28 automatically moves the column 13 to its original position when the pressing force of the cylinder on the column 13 is released. This is a coil spring that allows the cylinder to return to its original position and prevents it from moving too far due to inertia when it moves to the right due to the action of the cylinder.

The moving distance of the support column 13 can be adjusted by appropriately setting the installation interval of the flanges 27, etc., by widening the gap between each housing part 14, that is, by widening the linear body 8 by a predetermined distance and mounting it on the transfer belt. This facilitates handling of the linear body 8 in subsequent packaging steps and the like.

Next, to explain the function of the fixed length cutting device for a linear body of this invention, first, the housing section 14 is stored in the rotary cutter 1 (see Fig. 3), and the single-shaped pressure feeding section 18 is retreated to separate the two. Open the top surface 1. The elongated linear body 8 is placed on the bottom part 19 of the single-shaped pumping section 18 from above.

Next, the cylinder 22 is driven so that the single-shaped pumping section 18
advance toward the rotating rotary cutter 1 (
(See Figure 4).

At this time, the linear body 8 is cut without being tilted while being sandwiched between the rotary cutter 1 and the straight-shaped pressure feeding section 18, and is stored in the housing section 14.

After cutting, the support 13 is rotated and the accommodating portion 14 is also taken out from between the rotor no cutters 1.

Thereafter, by operating the cylinder to move the support 13, the cut linear bodies 9 are spread apart by a predetermined range, and then the linear bodies 9 are placed on a transfer belt laid at the bottom of the apparatus.
to fall.

After that, the above steps are repeated again.

Reference numeral 29 is a board for the broken waste of the linear body 8.

Since the device for cutting a linear object to a fixed length according to this invention is constructed as described above, it is possible to cut a linear object to a fixed length within a dimensional error range of about 1 to 3 mm.

Therefore, the occurrence of defects in packaging operations can be prevented, and the burden of inspection processes can be significantly reduced.

In addition, the linear body 8 does not break on the way, and the cutting conditions can be easily checked, making maintenance and management very easy.

Moreover, since the rotating shaft 12 is compact and smooth, the storage space for the linear body 8 is the same as in the conventional drum system, but there is more space, and the cutting chips fall onto the transfer belt. Since the attachment plate 29 can be attached to prevent this from happening, the defective rate of products can be significantly reduced.
