Description

  The present invention relates to a container dismantling apparatus that cuts and dismantles a container such as a milk pack.

  When a rectangular cylindrical paper pack (milk pack, etc.) used as a container for milk or juice is cut and disassembled for the purpose of recycling resources, scissors and cutters have been used as tools.

However, it was difficult to cut the corners of the container without meandering with the above tools. Therefore, for example, in the paper pack container cutting tool described in Japanese Utility Model Laid-Open No. 7-9267 (Patent Document 1), a blade is provided on a substantially L-shaped substrate, and the paper pack and the substrate are brought into close contact with each other. Thus, the corners of the paper pack can be cut without meandering.
Japanese Utility Model Publication No. 7-9267

  However, in the paper pack container cutting tool, the container is always pressed against the substrate by the blade when the container passes through the blade. Since the path of the container is narrowed by the blade, a large force is required to pass (cut) the container. That is, the passage resistance is increased during cutting.

  When a large force is required for cutting the container, the stopping position of the cutting tool becomes difficult to control due to the momentum of the cutting tool to which the force is applied. Moreover, when many containers are cut, a large force is required for each cutting, which places a heavy burden on the user.

  This invention is made | formed in view of such a situation, and it aims at providing the container dismantling apparatus which can cut | disconnect and disassemble a container more smoothly, without applying big force.

  A container disassembling apparatus according to the present invention is a container disassembling apparatus for cutting and disassembling a container in which at least a first container wall and a second container wall are bent in a substantially ridge shape, and is in sliding contact with the first container wall. The guide portion formed by bending one guide surface and the second guide surface slidably in contact with the second wall substantially in the shape of a valley, and the direction in which the container is guided by the guide portion is defined as the guide advance direction, and the guide advances from the guide portion. A trough extension extending in the direction, and a blade portion that is located on the extension line of the trough line of the guide portion and protrudes substantially equiangularly from the trough extension portion with respect to the first guide surface and the second guide surface, The extension part is a relief part that is recessed from the guide part.

  According to the said structure, a container is guided to a trough extension part, slidingly contacting a guide part. And if a container approachs a valley extension part, a container will be cut | disconnected by the blade part provided in the valley extension part. In this configuration, a trough extension portion extending from the guide portion in the guide traveling direction serves as a relief portion, and a blade portion is provided in the relief portion. In other words, in this configuration, at least the periphery of the blade portion is a relief portion.

  Therefore, according to this configuration, when the container passes through the blade portion (when cutting), the passage of the container around the blade portion is increased by the amount of the escape portion. That is, the escape portion allows the container to open when the blade portion passes (escapes), and the container easily passes through the blade portion. Furthermore, since the guide part prevents meandering (position shift) of the container, the container can be stably and reliably guided to the blade part.

  According to this configuration, meandering is prevented by the guide portion, and passage resistance at the time of cutting is reduced by the relief portion. Therefore, no great force is required for cutting the container, and the container can be cut more smoothly.

  Here, it is preferable that the valley extension is formed by a first relief surface that is recessed from the first guide surface and a second relief surface that is recessed from the second guide surface. Thereby, the trough extension part used as an escape part can escape the container cut | disconnected by the blade part in the direction where both a 1st container wall and a 2nd container wall open, when a container passes a blade part. Therefore, the container can be cut more smoothly.

  Here, it is preferable that the first relief surface and the second relief surface escape from the first guide surface and the second guide surface by at least the total thickness of the blade portion. For example, when there is no relief part, when the container passes through the blade part, the container is pressed against both guide surfaces by the thickness of the blade part. Accordingly, the container is less likely to pass through the blade portion (passage resistance is increased), and a strong force is required.

  However, by adopting the above-described configuration, it is possible to release the container having the thickness of the blade portion that is pushed out to the both surfaces by the blade portion. That is, when the container passes through the blade part, it is possible to prevent the cut containers (first container wall and second container wall) from being pressed against the first relief surface part and the second relief surface part by the blade part. Thereby, passage resistance reduces and a container can pass a blade part smoothly, without being pressed on both surfaces by a blade part.

  Here, in the container dismantling apparatus of the present invention, the valley bottom of the valley extension part is a deep part recessed from the valley line of the guide part. Thereby, the passage resistance of the container in the base of a blade part can be reduced reliably.

  Here, it is preferable that the blade portion has an inclined blade along an inclination that retreats as it goes in the guide traveling direction. Thereby, a blade can be put diagonally with respect to a container, and a container can be cut | disconnected, without applying force strongly.

  Here, it is preferable that the container disassembling apparatus of the present invention has a transparent body that can see through at least the periphery of the blade portion. Thereby, the operator can perform the cutting operation of the container while confirming the cutting state of the container. Further, since the blade portion can be seen at a glance in the apparatus, it is safer.

  Moreover, it is preferable that the container disassembling apparatus of the present invention further includes an openable / closable lid that covers at least the blade portion. Thereby, since it can cover a blade part with a cover body except at the time of use, it becomes still safer.

  According to the container disassembling apparatus of the present invention, the container can be cut and disassembled more smoothly without applying a large force.

  Next, the present invention will be described in more detail with reference to embodiments.

<First embodiment>
The container dismantling apparatus 1 of this embodiment is demonstrated with reference to FIGS. FIG. 1 is a perspective view showing a container disassembling apparatus 1. FIG. 2 is a diagram illustrating a usage state of the container disassembling apparatus 1. FIG. 3 is a plan view of the container disassembling apparatus 1. FIG. 4 is a front view of the container dismantling apparatus 1. FIG. 5 is a rear view of the container disassembling apparatus 1. 6 is a cross-sectional view of the container dismantling apparatus 1 taken along line AA in FIG. 7 is a cross-sectional view of the container dismantling apparatus 1 taken along line BB in FIG. 8 is a cross-sectional view taken along the line CC of FIG. FIG. 9 is a cross-sectional view taken along the line DD in FIG. 10 is a cross-sectional view of the container disassembling apparatus 1 taken along line EE in FIG.

  The container dismantling apparatus 1 is an integrally molded product, and includes a main body 10 made of resin such as acrylic and a blade 13 made of steel. The main body 10 includes a first main body portion 11 and a second main body portion 12. The 1st main-body part 11 is a substantially rectangular parallelepiped shape as a whole, and has the guide part 2 extended in a longitudinal direction on the upper surface. In the guide portion 2, the first guide surface 21 and the second guide surface 22 are bent at a right angle in a substantially valley shape.

  Here, as shown in FIG. 2, the paper pack 9 has a first container wall 91 and a second container wall 92, and one corner of the paper pack 9 is bent at right angles in a ridge shape. It has become. That is, when using the container disassembling apparatus 1, the first container wall 91 is in sliding contact with the first guide surface 21, and the second container wall 92 is in sliding contact with the second guide surface 22. The angle formed between the first guide surface 21 and the second guide surface 22 is not limited to a right angle, and may be an angle corresponding to the angle formed between the first container wall and the first container wall of the container to be cut. Further, from the viewpoint of reducing the sliding contact resistance, the angle may be slightly larger (1 to 2 degrees) than the angle formed by the first container wall of the container to be cut and the first container wall.

  The guide unit 2 guides the paper pack 9 from one end portion in the longitudinal direction toward the other end portion in the longitudinal direction. In this way, the direction in which the paper pack 9 is guided by the guide unit 2 (the direction in which the paper pack 9 travels) is defined as the guide traveling direction. Further, the direction opposite to the guide traveling direction is referred to as a guide entrance direction.

  The second main body portion 12 is provided integrally with the first main body portion 11 on the guide traveling direction side of the first main body portion 11. On the upper surface of the second main body portion 12, there is a trough-shaped (concave) trough extension portion 3 that continuously extends from the guiding portion 2 in the guiding traveling direction.

  The valley extension 3 includes a first relief surface 31 and a second relief surface 32. The first relief surface 31 is connected to the first guide surface 21 and is recessed from the first guide surface 21. The second relief surface 32 is connected to the second guide surface 22 and is recessed from the second guide surface 22. Specifically, the shape surrounded by the cross section of the valley extension 3 (substantially semi-elliptical) rather than the area of the shape surrounded by the cross section of the guide portion 2 (right isosceles triangle) with the upper surface of the main body 10 as one side. Is larger (see FIGS. 4, 8 and 9). Furthermore, the said area of the trough extension part 3 is gradually enlarged as it goes to a guidance advancing direction.

  Here, the first relief surface 31 and the second relief surface 32 have escaped from the first guide surface 21 and the second guide surface 22 by at least the total thickness of the blade portion 13. That is, the left-right width at each depth (excluding the top surface) of the valley extension 3 where the blade 13 is disposed is larger than the thickness of the blade 13 with respect to the left-right width of the guide 2. However, the left and right widths of the guide part 2 and the valley extension part 3 on the upper surface may also be increased as going in the direction of guide travel.

  Furthermore, the valley bottom of the valley extension 3 is recessed deeper than the valley 2a of the guide 2 (a right vertex of an isosceles right triangle). Specifically, the valley bottom of the valley extension 3 is gradually recessed toward the bottom surface side of the second main body portion 12 as it goes in the guide traveling direction. That is, the valley extension 3 is a relief portion that is recessed to the outer surface side (side surface and bottom surface side of the second main body portion 12) than the guide portion 2, and the valley bottom is deeper than the valley line 2a (to the bottom surface side). ) It has a deep abyss. The relief portion is formed by the first relief surface 31 and the second relief surface 32.

  The blade portion 13 is disposed on the extension line of the valley line 2 a of the guide portion 2 and at a position slightly entering the valley extension portion 3 from the guide portion 2. The blade part 13 protrudes from the valley extension part 3 at substantially the same angle (45 degrees) with respect to the first guide surface 21 and the second guide surface 22 at this position. The exposed portion of the blade portion 13 is substantially triangular, and the guide inlet direction side is a blade 13a. The guide entrance direction side of the blade portion 13 has an inclination (substantially triangular side) that recedes as it goes in the guide traveling direction. The blade 13a is an inclined blade along an inclination that retreats as it goes in the guide traveling direction. That is, the blade part 13 has the inclined blade 13a. As shown in FIG. 6, the inclined blade 13a is inclined approximately 135 degrees (greater than 90 degrees and smaller than 180 degrees) with respect to the valley line 2a.

  The blade portion 13 is partially embedded in the second main body portion 12 (insert), and the apex of the exposed portion is located on the bottom surface side of the upper surface of the second main body portion 12. That is, the blade portion 13 does not protrude beyond the upper surface of the second main body portion 12 and is accommodated in the valley extension portion 3.

  When using the container disassembling apparatus 1, if the blade 13a is applied to a position where it is desired to start cutting on the line where the two surfaces of the paper pack 9 (container) are in contact with each other at right angles, Can be cut. Then, by sliding the hand toward the guide entrance direction, the paper pack 9 advances in the guide progress direction, and the paper pack 9 (container) can be easily cut.

  Here, according to the container cutting device 1, since the relief portion is formed around the blade portion 13 (the blade portion 13 is disposed in the valley extension portion 3), the paper can be smoothly fed without applying a strong force. The pack 9 can be cut. Further, the guide unit 2 can stably cut along the guide traveling direction (along the line of the paper pack 9) without meandering.

  In addition, the bottom view of the container demolition apparatus 1 is shown in FIG. 11, and the right side view is shown in FIG. The left side view is the same as FIG.

  In the present invention, the relief portion that is recessed from the guide portion 2 may be at least around the blade portion 3. That is, the relief part should just be formed from the edge part position by the side of the guidance entrance direction of the blade part 3 to the edge part position by the side of a guidance advancing direction. This also reduces the passage resistance around the blade portion 3. However, in this embodiment, the relief portion is formed from the guide entrance direction side to the guide travel direction side end of the second main body portion 12 (main body 10) slightly from the guide entrance direction side end of the blade portion 3. For this reason, the container can be cut even more smoothly.

  Further, when the container cutting device 1 is not used, a lid 8 as shown in FIG. 13 may be provided in order to prevent a finger or the like from touching the blade 13a. The lid 8 is put on the upper surface of the main body 10.

  Moreover, it is good also considering the at least blade part 13 periphery of the 2nd main-body part 12 as a transparent body which can see through the blade part 13 periphery. Only the main body 10 or the second main body portion 12 may be formed of a transparent (translucent) resin or the like. Thereby, the operator can perform the cutting operation of the container while confirming the cutting state of the container. Further, since the blade portion 13 is located in the apparatus at a glance, it is safer. When the main body 10 is a transparent body, for example, as shown in FIGS. 14 and 15, the outer peripheral design of the main body 10 is partially changed (it is more square than in FIG. 1). The guide part 2 and the valley extension part 3 have the same shape.

  The main body 10 may be wooden. Further, the lid body 8 may be a transparent body so that the position of the blade portion 13 can be easily visually confirmed even when not in use (see FIG. 16). Moreover, the shape of the valley extension part 3 (relief part) may be tapered. Moreover, when setting it as this structure, passage resistance can be reduced further by making the thickness of the blade part 3 small. Moreover, the position of a blade part can be easily confirmed by attaching | subjecting one point (mark) to the both sides | surfaces by the side of the guide advancing direction of the container demolition apparatus 1 (or cover body 8).

<Second embodiment>
A container disassembly apparatus 100 according to a second embodiment will be described with reference to FIGS. FIG. 17 is a perspective view showing the container disassembling apparatus 100. FIG. 18 is a plan view of the container disassembling apparatus 100. FIG. 19 is a front view of the container dismantling apparatus 100. 20 is a cross-sectional view taken along line AA in FIG. 21 is a cross-sectional view of the container dismantling apparatus 100 taken along line BB in FIG. 22 is a cross-sectional view of the container dismantling apparatus 100 taken along the line CC in FIG. FIG. 23 is a cross-sectional view taken along the line DD in FIG. FIG. 24 is a right side view of the container dismantling apparatus 100. FIG. 25 is a view showing the container disassembling apparatus 100 covered with a transparent lid 80. In addition, about the same structure as 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The container dismantling apparatus 100 consists of the main-body part 10 and the blade part 13 like 1st embodiment. The main body 10 includes a first main body 11 and a second main body 120. The second main body portion 120 is provided integrally with the first main body portion 11 on the guide traveling direction side of the first main body portion 11. On the upper surface of the second main body 120, there is a trough-shaped (concave) trough extension portion 30 that continuously extends from the guiding portion 2 in the guiding traveling direction.

  Here, unlike the first embodiment, the left and right edges of the second main body 120 are formed with inclined portions 120a that are gradually inclined downward in the guide traveling direction. In other words, the upper part of the valley extension 30 is provided with an inclined part 120a that inclines downward as it goes in the guide traveling direction.

  The valley extension 30 is further recessed left and right than in the first embodiment. That is, the first relief surface 31 and the second relief surface 32 are larger than the thickness of the blade portion 13 and escape from the first guide surface 21 and the second guide surface 22. Accordingly, the left and right widths of the inclined portion 120a are smaller than the upper end edge portion of the first main body portion 11.

  The position of the blade portion 13 is closer to the guide traveling direction than in the first embodiment. The apex of the blade portion 13 (the upper end of the inclined blade 13a) is located below the inclined portion 120a when viewed from the side. In other words, in the positional relationship in the guidance traveling direction, the inclined portion 120a and the apex of the blade portion 13 overlap. In the guide traveling direction, the starting point of the inclined portion 120a is closer to the guide entrance direction than the apex of the blade portion 13. The starting point of the inclined portion 120 a is located above the apex of the blade portion 13. In addition, the end point of the inclined portion 120 a is at the end of the valley extension portion 30 on the guide traveling direction side. The end point of the inclined portion 120 a is located below the apex of the blade portion 13.

  Here, the effect of the container dismantling apparatus 100 of 2nd embodiment is demonstrated. In the container disassembling apparatus 100, the second main body 120 is provided with an inclined portion 120a. Further, the apex of the blade portion 13 is closer to the guide traveling direction side and is located below the inclined portion 120a in a side view. According to this configuration, even when the angle formed by the first wall 91 and the second wall 92 of the paper pack 9 is greater than 90 degrees, the blade portion 13 can be brought into contact with the ridge portion. Specifically, by cutting the inclined portion 120a so as to contact the paper pack 9, the blade portion 13 can contact the ridge portion and can be cut. When the inclined portion 120a is brought close to the paper pack 9 so as to sandwich the ridge portion, the blade portion 13 and the ridge portion approach each other and can be brought into contact with the object to be cut.

  For example, the angle between the upper part of the milk pack (the substantially triangular prism part to be opened) and the body part (cuboid part) is greater than 90 degrees (for example, about 110 degrees). In the second embodiment, the joint portion can be easily cut as well as the body portion.

  In addition, since the left and right widths of the inclined portion 120a are reduced, the blade portion 13 and the object to be cut can be brought closer to each other.

  As mentioned above, according to the container dismantling apparatus 100 of 2nd embodiment, in addition to the function of 1st embodiment, it can cut | disconnect easily also with respect to the ridge part with a large angle. As in the first embodiment, the container disassembling apparatus 100 may be covered with a transparent lid 80. Moreover, in 2nd embodiment, a rear view, a bottom view, and EE sectional view are the same as that of 1st embodiment.
