DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. Although the cutting device of this embodiment is used for both the cutting of empty cans and the cutting of bouquets, the cutting device of the present invention can also be used for cutting other articles. Of course.

As shown in FIGS. 1 to 3, a cutting apparatus 1 according to this embodiment includes an apparatus main body 10, two types of input boxes 20, 30 and a cutting unit 40. The apparatus main body 10 has a vertically long box shape, and a partition plate 13 for dividing the internal space into an upper space 11 and a lower space 12 is provided inside the main body 10. This partition plate 1

It is possible to install or replace the cutting unit 40 in the upper space 11 or to inspect the cutting unit 40 by flipping them up. A mounting hole 14 is formed at the upper end of the front surface 10a. As will be described later, one of the input boxes 20 and 30 is attached to the attachment hole 14 corresponding to the article to be cut.

As shown in FIG. 2, a portion of the front portion 10a below the partition plate 13 is a door 15 rotatable around one side, and the door 15 allows the lower space 12 to be rotated. Can be opened and closed. In the lower space 12, a waste receiving box 16 is housed so that it can be inserted and removed. The dust receiving box 16 accommodates a cut piece of an article (an empty can or a bouquet in this embodiment) cut by the cutting unit 40.

A cutting unit 40 is provided on the partition plate 13.
Is placed. This cutting unit 40 is for cutting an article put into the upper space 11 from either of the input boxes 20 or 30, and as shown in FIGS. 6 and 8, a pair of end plates 41A and 41B are connected to each other. Have. These end plates 41A and 41B are arranged in parallel with the left and right side portions 10c of the apparatus main body. End plates 41A, 4
1B are connected and fixed to each other by a plurality of connecting shafts 42 arranged therebetween.

A pair of drive shafts 43A, 43B penetrating the end plates 41A, 41B are rotatably supported on the end plates 41A, 41B, respectively. The pair of drive shafts 43A and 43B are arranged parallel to each other and horizontally. However, the drive shaft 43A is disposed obliquely above the rear so as to be located slightly above the drive shaft 43B. Of course, both drive shafts 4
3A and 43B may be arranged at the same height.

An input gear 44, which is rotationally driven in the direction of arrow A in FIG. 6 by a drive source (not shown) such as a motor, is non-rotatably attached to one end of the drive shaft 43A protruding outward from the end plate 41A. Have been. On the other hand, transmission gears 45A and 45B are non-rotatably attached to the other end protruding from the end plate 41B of the drive shaft 43A and the end of the drive phrase 43B on the same side thereof. Transmission gear 45A,
45B are in mesh with each other. Therefore, drive shaft 4
When 3A is driven to rotate in the direction of arrow A, drive shaft 43B is driven to rotate in the direction opposite to drive shaft 43A (direction of arrow B in FIG. 1). Moreover, since the transmission gears 45A and 45B have the same gear specifications, the drive shaft 43B is driven to rotate at the same speed as the drive shaft 43A.

A plurality of rotating blades 46A and a plurality of sets of spacers 47A, each of which is a set of two, are non-rotatably provided at a portion of the drive shaft 43A located between the end plates 41A and 41B. The rotary blade 46A and the set of spacers 47A are alternately arranged. Similarly, a plurality of rotary blades 46B and a plurality of sets of spacers 47B are non-rotatably and alternately arranged on the drive shaft 43B. Rotary blades 46A, 46B
Are alternately arranged in the axial direction of the drive shafts 43A, 43, and the outer peripheral portion of one rotary blade 46A (46B) is the other two rotary blades 46B, 46B (46A, 46A).
Between the two. Moreover, the rotary blade 26
The thickness of A is set substantially equal to the thickness of the pair of spacers 47B, 47B, and the thickness of the rotary blade 46B is set substantially equal to the thickness of the pair of spacers 47A, 47A. Therefore, the outer peripheral side portions of the side surfaces of the two adjacent rotary blades 46A and 46B substantially contact each other. As shown in FIG. 1, the rotary blades 46A and 46B are driven to rotate in the directions of arrows A and B, respectively, so that the rotary arrows 46A and 46B start to contact from the upper portion indicated by reference numeral D in FIG. The contact ends at the lower point shown. The outer diameters of the rotary blades 46A and 46B and the spacers 47A and 47B are set to dimensions such that their outer circumferences do not contact each other.

The rotary blade 46A is, as shown in FIG.
Two halves 46 having the same shape and the same size as each other
And a A _1, 46A _2. Half body 46A ₁ , 46
A ₂ is formed in a disc shape, a number of blade portion 46a facing the rotational drive direction (arrow A direction in FIG. 1) are arranged and formed at equal intervals in the circumferential direction on its outer peripheral portion. Each half 46
Each of the blade portions 46a, 46a of A ₁ , 46A ₂ is formed as a straight blade parallel to the axis of the rotary blade 46A. Moreover, the one blade portion 46a and the other blade portion 46a halves 46A ₂ halves 46A ₁ are located at the same position in the circumferential direction to form a blade portion of the continuous one. Of course, each half 46A _1, 46A ₂ of the blade section 46a, 46a is
A torsion blade inclined with respect to the axis of the rotary blade 46A may be used. Even in such a case, each half 46A ₁ ,
46A ₂ of the blade section 46a, for 46a, is preferably disposed so as to constitute one continuous blade portion.

The rotary blade 46A is connected to two halves 46A ₁ , 46A.
For the following reasons was constructed from A _2. That is, each half 46A _1, 46A ₂ of the blade section 46a, 46a, the code i,
It is easy to chip off at the outer corner shown by b. If the entire rotary blade 46A is formed integrally, the rotary blade 46A must be replaced if the outer corners a and b are missing. However, the rotary blade 46A is connected to the two halves 46A.
With the configuration of A ₁ , 46A ₂ , if the corners A, B are missing, the halves 46A ₁ , 46A ₂ are rearranged so as to be located on opposite sides, and the missing corners A, B are placed inside. In addition, by locating the corner portion, which has been located in the past, to the outside, the rotary blade 46A can be used even after the corner portions a and b are chipped.
This is because it is possible to improve the life of the rotary blade 46A.

On the outer periphery of the rotary blade 46A, a number of pockets 46b are provided adjacent to each other in the circumferential direction.
46a. The pocket portion 46b is for temporarily accommodating the cutting pieces, and has a depth slightly smaller than the maximum contact length L (see FIG. 1) in the radial direction of the two rotary blades 46A and 46B. I have.

The rotary blade 46A configured as described above is
The blade portion 46a of each rotary blade 46A is arranged on the drive shaft 43A such that it is located on a virtual spiral. That is, assuming that the number of blade portions 46a of the rotary blade 46A is N, each rotary blade 4A
The blade part 46a of 6A is arrange | positioned on the spiral of N ports.
Thus, the blade portions 46a of the two rotary blades 46A adjacent to each other in the axial direction of the drive shaft 43A are arranged at different positions in the circumferential direction.

The rotary blade 46B has the same construction as the rotary blade 46A, and has a rotary blade 4 with respect to the drive shaft 43A.
It is arranged on the drive shaft 43B in the same manner as the arrangement of 6A. Thus, for the rotary blade 46B, the same parts as those of the rotary blade 46A are denoted by the same reference numerals, and description thereof will be omitted. The rotary blade 46A and the rotary blade 46B may be configured such that when one blade 46a of the rotary blade 46A reaches the contact start point D, the blade 46a of the rotary blade 46B also reaches the contact start point D. However, it is desirable to arrange so as to be located at a position shifted from the contact start point D.

Between the pair of end plates 41A and 41B, there are disposed pieces 48A and 48B. Each of the cutting piece dropping members 48A, 48B is supported and fixed by a connecting shaft 42, 42, respectively.
Are arranged so as to surround the part of the outer peripheral side opposite to the side in contact with each other.

On the portion of the cut-off member 48A facing the outer periphery of the rotary blade 46A, convex portions 48a and concave portions 48b are formed alternately. The protrusion 48a has a width between two rotary blades 46A, 46A (two spacers 47A, 4A).
7A), and penetrates between two adjacent rotary blades 46A. Convex part 48
The penetration amount of a is set slightly larger than the depth of the pocket 46b. On the other hand, the width of the concave portion 48b is slightly wider than the thickness of the rotary blade 46A, and the outer peripheral portion of the rotary blade 46A enters into the concave portion 48b. The amount by which the rotary blade 46A enters the recess 48b depends on the amount of the pocket 46b.
Is set slightly larger than the depth. Similarly, convex portions 48a and concave portions 48b are formed alternately at a portion of the cut-off member 48B facing the outer periphery of the rotary blade 46B. Since the convex portion 48a and the concave portion 48b are the same as the convex portion 48a and the concave portion 48b of the fragment dropping member 48A, the description is omitted.

Guide plates 49A and 49B extending from one end to the other are arranged and fixed between the end plates 41A and 41B. As shown in FIG. 1, the upper end of the guide plate 49 </ b> A is connected to the lower end of the cutout falling member 48 </ b> A with almost no gap, and the lower end reaches the upper surface of the partition plate 13. On the other hand, the upper end of the guide plate 49B is connected to the lower end of the cut piece dropping member 48B with almost no gap.
The lower end reaches the upper surface of the partition plate 13. As a result, the rotary blades 46A, 46B, the spacers 47A, 47B,
Cut-off pieces 48A, 48B, guide plates 49A, 49
A discharge space S is defined by B and the partition plate 13. The discharge space S is open to the lower space 12 through a discharge hole 13a formed in the partition plate 13. Therefore, the cut pieces of the articles cut by the cutting unit 40 are stored in the waste receiving box through the discharge space S and the discharge holes 13a. The shape and size of the discharge hole 13a are substantially the same as a square defined by the pair of end plates 41A and 41B and the lower ends of the guide plates 49A and 49B.

In the opening 14 of the apparatus main body 10, input boxes 20, 30 are interchangeably mounted. That is, the charging box 20 is used for the empty can C
As shown in FIG. 4, it is formed in a substantially square box shape having an open back surface. A mounting plate 21 extending left and right is fixed to the upper surface of the input box 20. Bolt insertion holes 2 are provided at ends of the mounting plate 21 protruding left and right from the input box 20.
1a is formed. As shown in FIG. 1, the insertion box 20 is inserted into the mounting hole 14 so that the back side thereof can be inserted into and removed from the mounting hole 14 until the mounting plate 21 abuts on the front surface 10a of the apparatus main body 10. The bolt B inserted into the front box 10a of the input box 20
The main body 10 is screwed into screw holes 15 (see FIG. 3) formed on the left and right of the upper end of the main body of the apparatus.
It is adapted to be detachably fixed to the main body.

Inside the charging box 20, vertically extending partition plates 22, 22 are disposed and fixed, and the partition plates 22, 22 form two vertically extending passages 23, 22, respectively.
23 are formed. In the upper wall of the charging box 20 facing the upper ends of the passages 23, charging ports 24 for charging the empty cans C are formed, respectively. The input box 20 facing the input ports 24, 24.
An inclined surface portion 25 is formed at a lower portion on the front side of the device. The slope portion 25 is inclined from the front side to the back side as it goes downward. Therefore, when empty cans C are introduced from the inlet 24, the empty cans C slide on the slope 25 and enter the upper space 11 from the opened back as shown in FIG. The lower end of the empty can C that has entered the upper space 11 rides on the outer periphery of the contact start point D side of the rotary blades 46A and 46B, and the outer periphery of the intermediate portion is supported by the lower end edge 20b on the back surface of the input box 20. You. Moreover, since the empty box C is prevented from falling left and right by the partition plate 22 and the side wall 20a from the time when the charging box C is charged into the charging port 24 to the time when the empty box C hits the rotary blades 46A and 46B, the axis of the empty box C is prevented. To the rotary blade 46A,
It is maintained substantially perpendicular to the axis of 46B.

On the other hand, the input box 30 is used for cutting a bouquet (not shown), and as shown in FIG. 5, an upper portion 30a extending vertically and a rear side from the lower end of the upper portion 30a. Lower part 30 extending diagonally downward toward
b. The upper part 30a is formed in a tubular shape having a substantially square cross section with an open upper end. Meanwhile, lower 3
0b is formed in a chute shape with the top and rear ends open. One continuous passage 31 is constituted by the internal spaces of the upper portion 30a and the lower portion 30b. The opening at the upper end of the passage 31 is an input port 32. A rear portion of the upper portion 30a projects left and right from both left and right sides, and a bolt insertion hole 32
Are formed. And the input box 30
As shown in FIG.
The lower part 30b is the opening 1 until it hits the front part 10a of the
4 and the bolt insertion hole 33.
Is screwed into the screw hole 15 and tightened, so that the bolt B is detachably fixed to the apparatus main body 10.

Next, the operation of the cutting apparatus 1 having the above configuration will be described. When the empty can C is cut by the cutting device 1, the charging box 20 is attached to the device main body 10 in advance. Then, first, turn on the main switch (not shown)
Then, a drive source such as a motor is started. Thus, the rotary blades 46A and 46B are rotated in the directions of arrows A and B in FIG. Next, the empty can C is charged into the charging port 24 of the charging box 20. In this case, since there are two charging ports 24, one charging port 24 may be used for an aluminum can and the other charging port 24 may be used for an iron can. Of course, in that case, instead of the waste receiving box 16,
Either two waste bins are provided or a partition is provided at the center of the waste bin 16 so that the cut pieces of the empty cans C are not mixed.

The empty can C introduced from the introduction port 24 slides down the slope 25, and the lower end thereof is rotated by the rotary blades 46A, 46A.
B hits the outer circumference. In that state, the rotary blades 46A, 4
As the 6B rotates, the blade portions 46a of the rotary blades 46A and 46B bite into the empty can C. At this time, since the phases of the blade portions 46a of the rotary blades 46A and 46B are shifted, they do not bite at the same time but bite sequentially with the rotation. Therefore, the fluctuation of the load caused by the blade portion 46a biting into the empty can C can be kept small, and the vibration caused by the fluctuation of the load can be suppressed to a small value. Thereby, chipping of the blade portion 46a, especially chipping of the corner portions a and b can be prevented.

When the blade portions 46a of the rotary blades 46A and 46B bite into the empty can C, the empty can C becomes the rotary blades 46A and 46B.
Are pinched between them with the rotation of
A, 46B are cut into equal widths. Moreover, the cut piece is cut short by two blade portions 46a, 46a adjacent in the circumferential direction of the rotary blade 46A, and two blade portions 46a, 46a adjacent in the circumferential direction of the rotary blade 46B.
Cut short by. As a result, the empty can C is cut into a strip having a small width and a short length. The cut pieces of the cut empty cans C are supplied to the discharge holes 13 formed in the partition plate 13.
a, falls downward, and is stored in the waste receiving box 16.

Note that a part of the cut piece is formed by rotating blades 46A, 4A.
6B may be attached to or near the blade portion 46a, but the attached cutting pieces are removed when the rotary blades 46A, 46B pass through the respective recesses 48b of the cutting piece removing members 48A, 48B. It is scraped off by 48B.

Further, in the cutting apparatus 1, the empty cans C are fed so as to be substantially orthogonal to the rotary blades 46A and 46B, for the following reason. That is,
When the empty can C is fed in parallel with the rotary blades 46A and 46B,
The blade portion 46a will bite on the outer periphery of the empty can C. However, since the outer periphery of the empty can C is circular, the blade portion 46a
Slips on the outer periphery of the empty can C when it bites into the empty can C, or the empty can C rotates and the blade 4
The biting property of 6a deteriorates. As a result, the cutting time becomes longer. The bottom plate of the empty can C has four rotating blades 4.
Although it is divided by the blade portions 46a of 6A and 46B,
There is no separation by the two adjacent rotary blades 46A and 46B. For this reason, the bottom plate is crushed in a bellows shape and is pushed into the pocket 46b, and there is a possibility that the bottom plate is clogged in the pocket 46b.

In this regard, in the cutting apparatus 1, since the empty cans C are fed so as to be substantially orthogonal to the rotary blades 46A and 46B, the blade portions 46a can easily bite into the empty cans C. Therefore, the time required for cutting can be reduced. Moreover, the bottom plate of the empty can C is
Of course, it can be divided by two blade portions 46a which are adjacent in the circumferential direction.
A and 46B can be finely divided so as to reduce the width. Therefore, it is possible to prevent the bottom plate from clogging the pocket 46b.

On the other hand, when the bouquet is cut by the cutting device 1, the input box 20 is removed, and the input box 30 is attached instead. Also, the waste receiving box 16 is replaced with a bouquet. After that, the rotary blades 46A and 46B are rotated, and the bouquet is input from the input port 32 of the input box 30. The inputted bouquet enters the upper space 11 of the apparatus main body 10 through the passage 41. At this time, since one passage 41 is formed by the entire inside of the input box 30, the passage 41 can be widened. Therefore, a bouquet having a large volume can be smoothly moved to the upper space 11 side. The bouquet that has entered the upper space 11 is bitten between the rotary blades 46A and 46B, is pulled in, and is sequentially and finely cut like the empty can C. The cut pieces of the cut bouquet are stored in the waste bin 16.

As described above, in the cutting apparatus 1, the two input boxes 20, 30 are exchanged and used in accordance with the empty can C to be cut and the bouquet, so that one cutting apparatus 1 is used for two. Can be subjected to the cutting of two different articles. Therefore, the equipment cost can be reduced by half as compared with the case where the cutting device is provided for each of the cutting target articles.

[0032]

As described above, according to the first aspect of the present invention, a single cutting device can cut a plurality of different articles to be cut such as empty cans and bouquets. Therefore, the effect that the equipment cost required for the cutting device can be reduced can be obtained. According to the invention according to claim 2, an effect is obtained that it is possible to cope with a large-volume cut target article and a small target article. According to the third aspect of the present invention, it is possible to shorten the time required for cutting an empty can, which is one article to be cut, and to cut the bottom of the empty can finely. Can be
