Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can press method and apparatus for crushing used empty cans of two-piece or three-piece cans.

[0002]

2. Description of the Related Art Used two-piece and three-piece cans used as containers for beverages such as juices and beers are collected and reused as raw materials from the viewpoint of effective use of resources and reduction of garbage. Have been. In order to recycle empty cans in this way, it is necessary to crush the empty cans to save space for transportation and storage. Conventionally, as a method of pressing and crushing an empty can, a method of crushing by pressing a peripheral surface from substantially a side of the empty can has been adopted. The reason for employing this method is that the pressing force required to crush the cylindrical empty can is small. There are various devices for implementing this method.For example, a device having a structure in which a rectangular base plate and a push plate having the same shape are rotatably connected on its short side is commercially available for home use. I have. In this method, an empty can is placed sideways on a base plate, and the push plate is pressed by hand or stepped on with a foot to crush the plate.

[0003] According to the above-described conventional empty can press method and apparatus, the crushed empty can attempts to crush the cylindrical side surface into a square shape, but the circular bottom plate or lid plate is made of steel or the like. It is hard to crush because it has increased rigidity,
As a result, the overall bulkiness could not be reduced. When the crushed empty can is forcibly crushed, as shown in FIG. 9, the bottom plate 61 and the cover plate 62 are folded to form two corner portions 63 on the peripheral wall, and the crushed empty can becomes a substantially octagonal flat body. However, this requires a strong crushing force, and it is difficult to crush the garbage at home to take out the trash. Further, since the corner portion 63 is cracked and the torn metal projects sharply, the bag or box to be stored may be torn or the hand of an operator may be damaged, resulting in low workability. Further, the crushed empty can becomes thin, but its area is relatively large, and since there are approximately eight corner portions 63, the crushed empty can is not stacked but is caught when a large number of pieces are stored. Sometimes it is vertical. In such a case, the space occupied by one empty can becomes large, and there is also a disadvantage that crushing is meaningless.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. A relatively small pressing force enables a high compression ratio to be crushed, and almost no corners are generated in the crushed empty can. It is an object of the present invention to provide an empty can press method and an apparatus thereof that can be easily crushed at home.

[0005]

According to the first aspect of the present invention, there is provided a two-piece or three-piece empty can having a circular lid plate, a circular bottom plate and a cylindrical peripheral wall. After providing two cuts parallel to the can axis on each of the two opposing surfaces of the peripheral wall surface, the band-shaped wall formed between the two cuts is pressed from the outside of the can to be depressed inward. An empty can press method characterized in that an empty can is pressed in the axial direction and crushed while the cylindrical peripheral wall of the empty can is supported by a cylindrical guide.

According to the second aspect of the present invention, two opposite surfaces of a cylindrical peripheral wall of a two-piece can or a three-piece can having a cylindrical bottom wall and a cylindrical peripheral wall are parallel to the can axis. A circumferential cut connected between the cut of the strip and the cut of the two cuts is provided, and upper and lower strip-shaped walls formed between the cut of the two strips and the cut in the circumferential direction are pressed from the outside of the can to insert the end into the inside. After being depressed in the direction, the empty can is pressed and crushed in the axial direction while supporting the cylindrical peripheral wall of the empty can with a cylindrical guide.

Further, in the invention of claim 3, a) a gripping bar and two plate-shaped axial cutting blades protruding with the gripping bar as a back and parallel to the gripping bar at both ends and the axial cuttings. An axial cutting blade of the cutting member, which has a pusher projecting in the center between the blades and protruding in the same direction as the axial cutting blade, and a cutting blade base provided near the lower end of the gripping rod, with the axial cutting blade of the cutting member inside. B) a pair of opposing peripheral surfaces, and b) a pair of mating peripheral surfaces having an upper opening and a slit for an axial crushing rod, into which an axial cutting blade of a pair of cutting members and a pusher can be inserted. A cylindrical guide formed at a pair of circumferential surface positions where the slit for the cutting blade in the axial direction and the insertion hole of the pusher are paired, and c) a guide mounting position on the upper surface. A guide peripheral position which engages with a tip portion of a gripping rod of the cutting member when the axial cutting blade and the pushing tool of the cutting member are fitted into the guide. A square plate-shaped base having two support holes, and d) a crush supported on the periphery of the base guide so as to be inserted into and removed from an upper opening in a crush rod slit of the guide mounted on the base. It is an empty can press equipped with a rod.

According to a fourth aspect of the present invention, in addition to the empty can press of the third aspect, the plate-shaped circumferential cutting blade is directed in the same direction as the axial cutting blade to form two shafts. A slit for the circumferential cutting blade, which protrudes from the cutting blade base in front of the pusher between the direction cutting blades and in which the circumferential cutting blade can be inserted, is formed between the slits for the axial cutting blade of the guide. It is an empty can press device characterized by the above-mentioned.

The operation of the above-described means will be sequentially described below. According to the empty can press method according to the first aspect, since a large pressing force is required to suddenly crush the empty can in the axial direction, the apparatus for realizing the method is sharply large and robust, and is simple. It is difficult to apply human power directly to the apparatus. Therefore, the empty can press method of the present invention provides two cuts parallel to the can axis on each of the two opposing surfaces of the cylindrical peripheral wall of the empty can before the empty can is pressed in the axial direction and crushed. Since the band-shaped wall formed between the two cuts is pressed from the outside of the can and dented inward,
The pressing force required to crush the empty can in the axial direction can be drastically reduced. For this reason, it can be easily crushed even by human strength.

Further, since the cylindrical peripheral wall of the empty can is pressed and crushed in the axial direction, little deformation is applied to the circular bottom plate or cover plate made of steel or the like having high rigidity. For this reason, the pressing force required for crushing is only the pressing force of the peripheral wall of the empty can in the direction of the can axis, and the pressing force can be easily crushed by reducing the pressing force as described above.

Since the hollow can is crushed in the axial direction of the can while supporting the cylindrical peripheral wall of the empty can with a cylindrical guide, the peripheral wall surface of the empty can is bent inward and finally laminated relatively densely. Compressed. Therefore, the crushed empty can has almost no protruding corners. Since such an action can be effectively exerted on a relatively soft aluminum can, this method is most suitable for crushing an aluminum can. Since there is no protruding corner in the crushed empty can, there is no damage to the worker's hand or the storage bag during the work of collecting, carrying in and out. Further, since the crushed empty cans do not catch on each other, the crushed empty cans can be densely stored only by dropping a large amount of crushed empty cans into a storage container such as a box.

Since the empty can is crushed in the axial direction while supporting the peripheral wall of the empty can with a cylindrical guide, the empty can after crushing has a shape substantially the same diameter as the empty can before crushing and only the height is reduced. Become. For this reason, the bottom of the empty can after crushing exists almost without cracks and the like, similarly to the empty can before crushing. Therefore, when the bottom is down, the liquid remaining inside stays at the bottom and does not leak out. In addition, since the side surface of the empty can is bent and dense inside, and the space formed at the bottom is substantially sealed, leakage of the residual liquid is reduced even if the crushed empty can is tilted or repeated. You.

According to the empty can pressing method of the present invention, two cuts in the axial direction of the can and two cuts in the circumferential direction are formed in each of the two opposing surfaces of the peripheral wall surface of the empty can. 2. The empty can press method according to claim 1, wherein the opposite ends of the upper and lower strip-shaped walls formed between the H-shaped cuts are bent inward, and then the empty can is pressed in the can axial direction to be crushed. In addition to the above-described operation, the pressing force required for crushing the empty can can be further reduced. Therefore, even a relatively hard material such as a steel can can be easily crushed.

According to the third aspect of the present invention, the guide is first placed on the guide mounting position of the base, and the empty can is inserted into the guide. Next, the axial cutting blades and the pusher of the two sets of cutting members are simultaneously pushed from both sides into the slits and pusher insertion holes for the axial cutting blades formed at a pair of circumferential surfaces of the guide, which are paired with each other. Two cuts in the axial direction are formed by the axial cutting blade at each of a pair of peripheral wall positions of the empty can, and the band-shaped wall between the two cuts can be depressed inward by the pushing tool. . At this time, since the support hole is provided at the base position to be engaged with the distal end portion of the gripping rod, a force is applied to the vicinity of the other end of the gripping rod with the distal end portion of the gripping rod inserted into the support hole. By applying the principle of leverage, the force required to form a cut in the peripheral surface of an empty can can be reduced. Further, by simultaneously pressing the axial cutting blades from the lateral direction against the opposed positions of the cylindrical peripheral wall surface of the empty can, the cutting operation can be performed while maintaining the stable state of the empty can and the guide. After such a cutting operation is completed, the two sets of cutting members are pulled out from the empty can, and finally, the crushed rod pivotally supported by the base is inserted into the crushed rod slit of the guide, and the vicinity of the end is pressed downward by hand. By applying the lever principle, the empty can can be easily crushed in the axial direction.
By using in this way, the empty can press method of the first aspect can be carried out, and the same operation as that described in the empty can press method of the first aspect can be obtained. Further, since the guide and the cutting member are made detachable, they can be removed and stored in a space-saving manner. In addition, according to the empty can press, the cut into the peripheral wall formed before the empty can is crushed in the axial direction of the can is a pair of two strips, that is, a total of four cuts. The crushing force can be reduced, and the pressing force required for the work can be set within the range of human arm strength. Furthermore, since the cutting member has a structure in which a pair of plate-shaped axial cutting blades are vertically protruded on opposite sides of a rectangular cutting blade base, both sides of a single square steel plate or the like are vertically set. It can be manufactured by a simple method such as bending or forming both ends into a blade shape.

According to the empty can pressing device of the fourth aspect, in addition to the two axial cutting blades of the empty can pressing device of the third aspect, a circumferential direction is perpendicularly provided between the axial cutting blades. A cutting blade was provided, and the entire cutting blade was formed into an H shape. A slit for the circumferential cutting blade was additionally formed in the guide so that the circumferential cutting blade could be inserted. Therefore, in addition to the two cuts formed in the peripheral wall of the empty can, which is an operation of the empty can press device of claim 3, a vertically connected cut in the circumferential direction can be formed between the two cuts. An H-shaped cut can be formed. For this reason, the strip-shaped wall formed between the two cuts is vertically divided. Further, since the pusher is divided vertically by the circumferential cutting blade, the opposite ends of the upper and lower strip-shaped walls can be bent inward. In this way, the surrounding wall of the empty can
An H-shaped cut is formed on each surface, and after the pretreatment in which the opposite ends of the upper and lower strip-shaped walls formed between the H-shaped cuts are bent inward, the empty can is crushed in the axial direction. Accordingly, the present invention is an apparatus capable of performing the empty can press method of claim 2, and therefore, the same operation as the operation of the empty can press method of claim 2 is obtained, so that the empty can is crushed in the axial direction. The required pressing force can be further reduced.

The crushing rod slit 24 is an axial slit having an upper opening, and has a width in which two crushing rods 5 to be described later can be inserted. did. Further, a pair of engaging pieces 25 are provided at the lower end of the guide 3 and below the pair of cut holes 21. The engagement piece 25 is a rectangular plate having the same thickness as the guide 3. The guide 3 can be locked to the base 2 by being fitted into the pair of support holes 17 of the base 2. In addition, the size of the guide 3 is adjusted to the empty can to be crushed.

(3) Cutting member FIGS. 4 (a), 4 (b) and 4 (c) respectively show FIGS.
FIG. 3 is a side view, a plan view, and a front view showing a cutting member of the empty can press device of FIG. The cutting member 4 is shown in FIGS.
As shown in (c), a cutting blade base 32 is attached to the gripping bar 31, and an axial cutting blade 33 and a pushing tool 34 are protruded from the cutting blade base 32. This gripping rod 31 is a quadrangular prism-shaped rod. The cutting blade base 32 is a substantially rectangular plate made of metal (steel or the like), and a cross section (including the short side) perpendicular to the long side is curved with a constant diameter. That is, a part of the side surface of the cylinder whose long side is the axial direction is formed. Further, the cutting blade base 32 is provided slightly above (at the center of) the lower end 35 of the gripping bar 31 so that the lower end 35 can be inserted into the support hole 17 of the base 2. Two axial cutting blades 33 protrude perpendicularly to a pair of long sides facing each other of the cutting blade base 32. Also axial cutting blade 3
Numeral 3 is a rectangular flat plate having a blade edge 36 formed on one side thereof, the blade edge 36 having a predetermined inclination with respect to the gripping bar 31 and the cutting blade base 32, and being easily cut into the empty can peripheral wall.
Further, the pushing tool 34 is in the shape of a rectangular parallelepiped, and the tip surface 37 is inclined lower than the cutting edge 36 of the axial cutting blade 33 (meaning that it is closer to the cutting blade base 32) and substantially inclining. It protrudes between the both axial cutting blades 33. Note that the gripping rod 31 may be a rod of about 15 mm square and about 30 cm. Also,
The axial cutting blade 33 is adjusted according to the empty can to be crushed, but the length of the cutting edge 36 is preferably about 8 cm. It is preferable that the pushing tool 34 can be pushed in by about 2 cm. A cut is formed in the side wall of the empty can, and the zone between the cuts is pushed inward.However, the interval between the axial cutting blades 33 is determined so that the pushed zone is almost the same as the non-pressed zone. Good.

(4) Crushing rod The crushing rod 5 is a rod-like body having a rectangular section substantially the same length as the base 2, as shown in FIGS. 1 and 2A and 2B. The base 2 is rotatably supported near both ends of the upper surface of the base 2 with the width direction of the base 2 as a rotation axis, and can be inserted into and removed from the slits 24 for both crushed bars of the guide 3 mounted on the base 2. did. When the crushing rod 5 is made of steel, its cross section is about 24 mm × 4.5.
It is possible with a square of mm and a length of about 40 cm.

(5) Crushed Plate FIGS. 5A and 5B are a plan view and a front view showing the crushed plate 6 of the empty can press device of FIG. 1, respectively. The crushing plate 6 is placed on an empty can held in the guide 3 and pressed by a crushing rod 5 from above, so that the upper surface of the empty can can be uniformly pressed. The crushing plate 6 is a metal disk having a predetermined thickness, as shown in FIGS. 3A and 3B, and has an inclined portion 41 having a predetermined angle at a position 180 ° opposite to the upper surface. That is, a relatively large chamfered portion was formed. The two crushing rods 5 are brought into contact with the two inclined portions 41 and pressed.

(6) Method of Use First, the guide 3 is set by inserting the pair of engagement pieces 25 of the guide 3 into the pair of support holes 17 of the base 2. Then, an empty can is inserted into the guide 3, and the crush plate 6 is inserted on the empty can. Next, the distal ends 35 of the gripping rods 31 of the two cutting members 4 are inserted into the pair of support holes 17 of the base 2 so that the axial cutting blade 33 and the pushing tool 34 match the cutting blade group 21. .
In this state, the outer end portions of the two sets of gripping rods 31 are gripped and simultaneously pinched in the direction of the guide 3 so that the axial cutting blade 33 and the pushing tool 34 are inserted into the slit 21 for the axial cutting blade and the pushing tool insertion hole. 23. As a result, four cuts are formed in the empty can, and the portion sandwiched between the pair of cuts can be pushed and bent in the center direction. Thereafter, the cutting member 4 is pulled out from the empty can, and both the crushing bars 5 are inserted into the crushing rod slits 24 of the guide 3 from above, and the crushing plate 6 and the empty can are vertically pressed to be crushed in the axial direction. The empty can can be taken out by removing the guide 3 from the base 2 after the empty can is crushed. The recesses 16 at both ends of the receiver 12
As shown in FIG. 6, this is for inserting and supporting the gripping bar 31 during the operation, but the blade edge 36 does not completely come out of the axial cutting blade slit 21 of the guide 3 in the supported state.
Adjusting the position so that it is slightly engaged makes the work easier.

According to the empty can press 1 described above, the empty can after crushing is crushed in the axial direction, as shown in FIG. That is, the side wall 57 is bent and the multi-layer structure is adhered to the multi-layer structure while the cover plate 55 and the bottom plate 56 are kept as they are. For this reason, the broken can does not have a projecting portion that is broken and bent, and the remaining liquid is less likely to leak.

Although the embodiment has been described above, the embodiment of the empty can press according to the present invention is not limited to this.
For example, by making the cut hole group 21 of the guide 3 into two pairs, or increasing the number of the axial cut blades 33 of the cut member 4,
By increasing the number of cuts in the axial direction formed in the empty can, the pressing force required for crushing the empty can in the axial direction can be reduced. In this way, even a relatively hard steel can can be easily crushed.

As an example of a form different from the above-described empty can press, an apparatus for forming a notch in the circumferential direction of the empty can peripheral wall in addition to the cut in the axial direction of the can as a pretreatment for the axial crushing of the empty can will be described. FIG. 7A shows a side view, a plan view, and a front view of the cutting member of the empty can press device, respectively.
(B) and (c), and a front view of the guide is shown in (c) of FIG. The components of the empty can press other than the cutting member and the guide are the same as those of the empty can press of FIGS. In the cutting member and the guide of the empty can press, the same parts as those of the empty can press of FIGS. The cutting member 4 of the empty can press is shown in FIGS.
As shown in (c), a circumferential cutting blade 51 is provided so as to protrude so that the cutting blade forms an H shape. More specifically, the circumferential cutting blade 51 has a plate-like shape with a mountain-shaped cutting edge, and is vertically provided on the cutting blade base 32 in the same direction as the axial cutting blade 33. Further, the circumferential cutting blade 51 is disposed at a position where the pusher 34 is vertically divided into two so as to vertically contact between the two axial cutting blades 33. On the other hand, the cut hole group 2 of the guide 3
As shown in FIG. 7 (d), 1 has two slits 22 for the cutting blade in the axial direction, a rectangular insertion tool insertion hole 23 between the slits 22 for the cutting blade in the axial direction, and the axial direction. A slit 52 for a circumferential cutting blade which is vertically connected between the slits 22 for the cutting blade so as to divide the center of the pusher insertion hole 23;
The two axial cutting blades 33 of the cutting member 4 and the pushing tool 3
4, and the circumferential cutting blade 51 can be inserted. According to this device, an H-shaped cut can be formed in the peripheral wall of the empty can, and the opposite ends of the upper and lower strip-shaped walls between the H-shaped cuts can be bent inward. By performing such a pretreatment, the pressing force required for crushing the empty can in the axial direction can be further reduced, and even a relatively hard steel can can be easily crushed.

[0026]

According to the empty can press method of the first aspect, the following effects can be exhibited. 1) Before the can is crushed in the axial direction, an axial cut is made in the peripheral wall of the can, and the band-shaped wall between the cuts is depressed inside, and a rigid steel circular bottom plate or lid plate is formed. Since no deformation is applied, the pressing force required to crush the empty can can be drastically reduced. For this reason, it can be easily crushed even by arm strength. As the number of cuts formed in the peripheral wall of the empty can is increased, the pressing force required for crushing the empty can in the axial direction is reduced, so that the size and strength of the empty can to be crushed and the force of the operator are reduced. It is advisable to make adjustments in consideration of such factors, but it is possible to sufficiently cope with aluminum cans and the like by forming two notches on each of the peripheral wall surfaces that are paired as in the present method.

2) Compared to the crushed empty can obtained by the conventional empty can pressing method, the crushed empty can obtained by the empty can pressing method of the present invention has almost no protruding corners. Therefore, during the work of collecting, carrying in and out, etc., there is no damage to the workers' hands or storage bags, and as a result,
The efficiency of recycling can be improved. Further, since the empty cans after crushing do not catch on each other, the empty cans can be stored relatively densely simply by dropping a large amount of the empty cans into a storage container such as a box. For this reason, compared with the conventional empty can press device, it is possible to improve the efficiency of operations such as collection, carrying in and out, and to promote the efficiency of transportation by saving the space for storage.

3) Since the empty can after crushing has the same diameter as the empty can before crushing and only the height is reduced, the bottom of the empty can is almost the same before crushing and after crushing. No cracks are generated. Further, since the peripheral surface of the empty can is bent and densified in several layers inside, the space formed at the bottom of the empty can after being crushed is substantially closed. Therefore, the liquid remaining in the empty can is collected at the bottom and can be made to have a structure that is hard to leak out during storage and transportation. For this reason, in the process of collecting and reusing the empty cans, the working environment and the inconvenience of the worker being polluted by the residues in the empty cans can be reduced, and the efficiency of recycling can be improved. From this point, recycling of empty cans can be promoted.

According to the empty can pressing method of the second aspect, the cuts formed on the two opposing surfaces of the peripheral wall surface of the empty can are formed in an H shape, so that the empty can pressing method of the first aspect is improved. Further, the pressing force required for crushing the empty can can be reduced. Therefore, even a relatively hard material such as a steel can can be easily crushed.

According to the empty can press apparatus of the third aspect, the empty can press method of the first aspect can be carried out by a relatively simple apparatus, and the same effect as the above-mentioned empty can press method of the first aspect can be obtained. The effect of can be exhibited. Furthermore, since the cutting member and the guide are configured to be detachable from the base, they can be removed and stored in a space-saving manner.

According to the empty can press apparatus of the fourth aspect, the apparatus can perform the empty can press method of the second aspect. Therefore, the same effect as the effect of the empty can press method of the second aspect is provided. The pressing force required to crush the empty can in the axial direction can be further reduced.
