Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry ice cutting device, and more particularly to a device for simultaneously cutting a dry ice block into a large number of thin plates.

[0002]

2. Description of the Related Art Generally, solid dry ice is manufactured as a cube of 25 cm on a side, and it is cut into two pieces according to the purpose.
Further, this is divided into 10 equal parts, 8 equal parts, 6 equal parts, etc., that is, cut into a plurality of thin plates to obtain a product. Conventionally,
A band saw was used in the work of cutting dry ice into a thin plate, but the use of this band saw is extremely dangerous and requires skill to cut into a uniform thin plate, and a large amount of cutting is required. In the work, the effort is extremely large, so that
A dry ice cutting device as described in Japanese Patent No. 029 was devised.

In the dry ice cutting device described in Japanese Utility Model Publication No. 63-39029, dry ice is put in a bracket having a large number of slits, the bracket is supported by a moving box, and the moving box is moved to make a large number of slits. The dry ice is cut into a plurality of thin plates at once in the bracket by passing it over a plurality of circular saws arranged corresponding to the intervals.

[0004]

However, in the above-mentioned conventional dry ice cutting apparatus, each time one piece of dry ice is cut into a thin plate, it has to be put into and taken out from the bracket, and the thickness of the thin plate to be cut out is also required. When changing the height, not only the intervals between the circular saws must be changed, but also another bracket having slits formed at intervals corresponding to this must be prepared, and dry ice rattles in the brackets. Since it hinders cutting, the size of the dry ice that can be cut must be a size that exactly matches the volume of the bracket.

The object of the present invention is to solve the above-mentioned conventional problems, and can be applied to the cutting of dry ice having different sizes continuously and having a thin plate shape having different thickness. It is to provide a dry ice cutting device that can be cut out very easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The dry ice cutting device of the present invention will now be described in more detail with reference to the embodiments shown in the drawings. 1 is a plan view of a dry ice cutting device 10 according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a right side view of the dry ice cutting device 10 of FIG. The dry ice cutting device 10 of this embodiment includes a conveyor device 12 having an endless carrier 11. The endless carrier 11 is composed of two parallel endless chains 1 as shown in FIGS.
3, and is composed of a large number of strip-shaped support plates 14 arranged in parallel and fixed.

The conveyor device 12 has a strip-shaped support plate 1 for the endless carrier 11, which is located on a carrier path for carrying an object (dry ice) from an inlet portion 15 to an outlet portion 16.
Two rails underneath 4 and slidably supporting it
7 (see FIG. 6), each of these two rails 17 is arranged along each of the endless chains 13. Endless carrier 11 located on this rail 17
For convenience sake, the surface of all the support plates 14 will be referred to as a transport support surface. Sprockets 18 serving as a driven vehicle and an original vehicle are installed on the inlet portion 15 side and the outlet portion 16 side of the conveyor device 12, and the endless chains 13 are hooked in parallel with each other. The sprocket 18, which is the original vehicle, has its rotary shaft connected to the drive rotary shaft of a drive motor 19, and is driven and rotated by the drive motor 19, thereby moving the endless carrier 11 at a constant speed.

Each strip-shaped support plate 14 constituting the endless carrier 11 is made of high-density polyethylene resin to support a very special object to be conveyed, that is, dry ice, that is, a very low temperature. It is supposed not to happen. These strip-shaped support plate 14, FIG. 4
Or As is clear from FIG. 6, the trapezoid shape of the end face
Is formed, and the top surface is a flat surface that supports dry ice.
It is regarded as a flat surface . Then, such a support plate 14,
When the endless chain 13 is mounted and fixed, the side edges on the lower surface side are arranged so as to be in close contact with the adjacent support plates 14 . Thus, the endless conveyor member 11, the shape and the arrangement of the support plates 14, each support plate
V shape as a storage space for dry ice chips between 14
A shaped space 20 is formed.

The dry ice cutting device 10 is further provided with side guard parts 21a and 21b which are disposed on the outer side of each endless carrier 11 of the conveyor device 12 and can reciprocate inward. This side guard part 21
Each of a and 21b is independently movable, and its means will be described below. Support rods 22 and 23 are respectively arranged on the inlet portion 15 side and the outlet portion 16 side so as to cross the upper portion of the convey path of the conveyor device 12. A slider 24 is provided on one end side of each of the support rods 22 and 23.
A and 24b are slidably mounted on the support rods 22 and 23.

One side guard portion 21a arranged outside the endless carrier 11 is connected to the lower portion of each slider 24a, 24b. Therefore, the side guard portion 21a has two sliders 24a, 24b. Will be suspended by. Further, similarly to this, the sliders 25a,
25b is slidably mounted on the support rods 22 and 23. The other side guard portion 21 is connected to and suspended from the sliders 25a and 25b.

These pairs of sliders 24a, 24b and 25a, 25b are connected by connecting rods 26, 27 for each pair. Therefore, each pair of sliders 24a, 24
b and 25a and 25b move integrally, and each side guard part 21a and 21b can be moved in parallel in the width direction of the endless carrier. Slider 24 on each side
Each connecting rod 2 for connecting a, 24b and 25a, 25b
Reference numerals 6 and 27 also serve as sliding means for sliding the slider with respect to the support rods 22 and 23. The sliding means will be described by taking the slider 24a and the connecting rod 26 as an example.

The end portion of the connecting rod 26 sandwiches the support rod 22 and bearings 28 mounted on the slider 24a on both sides thereof.
Are rotatably supported by the bearings 28 and are in contact with the upper portions of the bearings 28 in a state orthogonal to the support rods 22 exposed from the window 29 formed in the slider 24a. A handle wheel 30 for rotating operation is attached to the connecting rod 26 at a position adjacent to the slider 24a. As a result, when the connecting rod 26 is rotated, since it is in contact with the supporting rod 22 at the window portion 29 of the slider 24a, the connecting rod 26 rolls on the supporting rod 22, and as a result, the slider 24a slides on the supporting rod 22.

A rotary shaft 32, on which five circular saws 31 are attached at predetermined intervals, is extended and supported on the upper portion of the conveying support surface of the conveyor device 12 at an intermediate position in the conveying direction so as to extend in a direction traversing the endless conveying body 11. There is. The lower half of the center of each of the five circular saws 31 is located on the transport path on the transport support surface, and the lowermost portion of each circular saw 31 is particularly close to the transport support surface to a slight gap. ing. The rotary shaft 32 to which the circular saw 31 is attached is operatively connected to a drive rotary shaft of a motor 33 arranged on the side of the conveyor device 12 via a belt or the like. Reference numeral 34 indicates a protective cover attached so as to cover the upper half of the circular saw 31 to prevent danger.

Next, the dry ice cutting device 1 of this embodiment
The operation of 0 will be described. Conveyor device for dry ice blocks 1
Place it on the table 35 installed at the entrance 15 of the second
One side guard part 21a and the outermost circular saw 3
By rotating the handle wheel 30 so that the distance between the sliders 24 and 2 becomes the same as the distance between the circular saws 31, the sliders 24a, 2
The position of the side guard part 21a is adjusted by sliding 4b. Then, the other side guard portion 21 is similarly rotated and the position thereof is adjusted by rotating the handle wheel 30 so that the width between the both side guard portions is approximately the same as the width of the dry ice block.

When the motors 19 and 33 are turned on to operate the conveyor device 12 and the circular saw 31 and the dry ice block located at the inlet 15 is pushed into the transport path, the dry ice block is endless. The carrier 11 is carried on the carrier support surface, and the carrier proceeds accurately by the side guard portions 21a and 21b on both sides in the width direction without any fluctuation for one minute while maintaining the position relative to the carrier support surface. Then, the dry ice block is simultaneously cut by passing through the five circular saws 31, divided into six thin plate-like pieces, and sent out onto the table 36 of the outlet section 16.

In this case, the width dimension of the first dry ice block fed from the inlet portion 15 of the conveyor device 12 is 6 times the interval between the circular saws 31 (the thin plate-shaped piece cut out by the five circular saws 31 is 6). Unless it is adjusted to the dimensions (for the number of sheets), the thin plate-shaped piece on the side in contact with the other side guard portion 21 does not have a predetermined thickness, so this is discarded or further discarded by another means. It is cut and its thickness is adjusted.

When a plurality of thin plate-like pieces are cut out at the same time by a plurality of circular saws 31 as described above, a large amount of dry ice chips (powder) are discharged at one time, and most of them are piled up on the conveyance support surface. With the conventional endless carrier at the research / experimental stage
In order to drop the chips of this dry ice downward from the gap of the strip-shaped support plate, a relatively wide space was provided between them, and some of the chips fell between the rail and the bottom of the support plate. However, there is a problem in that the endless carrier floats up from the rail and comes into contact with the circular saw, and the supporting plate of the carrier is cut. However , the truth
In the example endless carrier 11 , each strip-shaped support is used.
The end surface shape of the plate 14 with a trapezoidal shape, and, (may be contacted if there is no operation on trouble of the endless carrier) manner, minute gaps in a side edge of the lower side shown in FIG. 5
Since the strip-shaped support plates 14 are arranged on the endless chain 13 by opening the chips 37, the chips 37 enter the V-shaped space 20 between the support plates 14 and the conveyor device 1 as it is.
2 is carried to the exit portion 16 side. Ie the above end
The flat surface of the upper surface of each support plate 14
Supports dry ice by surface contact.
I will reduce the slip of ice and transfer it securely,
Allows accurate cutting by 31. Moreover, each support plate
Since the space portion 20 between 14 functions as a tray portion for the dry ice chips 37 , the space portion 20 inside
Do this without dropping dry ice chips to the side
Carry to the exit side, so that the chips under the support plate 14
Prevents intrusion and prevents floating of the endless carrier 11.
Stop.

The dry ice chips 37 that have entered the V-shaped space 20 between the support plates 14 of the endless carrier 11 are moved by the sprocket 18 by the endless carrier 11 at the outlet 16 side of the conveyor device 12. Due to the curve drawn when turning downward to change the direction, the space on the transport support surface of the V-shaped space 20 widens and faces downward as shown in FIG. 4, so it falls naturally. , Removed. This eliminates the inconvenience that the chips of dry ice pile up on the rails to lift the endless carrier and the circular saw cuts the support plate.

[0022]

As described above, according to the dry ice cutting device of the present invention, the movable side guard portion accurately maintains the position of the dry ice in the width direction with respect to the transport support surface of the endless transport body. By allowing a large number of circular saws to ride on the endless carrier, dry ice can be continuously supplied, and even if the size of the dry ice is slightly different, it can be applied, and thin plate pieces with different thicknesses Even if the distance between the circular saws is changed to cut out the cutouts, it is only necessary to adjust the position of the side guard portion, and the productivity of cutting dry ice into a large number of thin plates can be significantly improved. Further, according to the dry ice cutting device of the present invention, in addition to the above-mentioned advantages, the strip-shaped support plates constituting the endless carrier are formed into an end face trapezoidal shape and arranged in close contact with each other, and the interval between them is V.
Since the dry ice chips are stored in this space as a letter-shaped space and are dropped off at the exit side of the conveyor device, there is no contact with the circular saw due to the lift of the endless carrier due to the dry ice chips. The operational reliability of the cutting device can be significantly improved.
