Abstract

PURPOSE:To enable a large amount of cut pieces, divided into a plural quantity in two horizontal longitudinal and lateral directions, to be automatically fed transferring at a time to a predetermined part by inserting a fork-shaped protrusive part into the bottom part of a cut line from either of the two longitudinal and lateral directions and lifting a fork unit of the protrusive part moving the cut piece. CONSTITUTION:From either horizontal longitudinal or lateral direction, a fork-shaped protrusive part 30 is first inserted into a bottom side cutting groove 10 positioned in the bottom part of a cut line 4c between cut pieces 4a. Next a fork unit, forming a fork-shaped protrusive part 30, is moved to the upper, lifting all the cut pieces 4a, cut in two horizontal longitudinal and lateral directions, from a bottom mold 6. Hereafter moving the fork unit in a horizontal direction, a group of the cut pieces 4a, cut into a plural quantity in the two horizontal longitudinal and lateral directions, is fed transferring at a time to a predetermined part. Here the fork-shaped protrusive part 30 cannot afford holding a cutting chip 4b generated in the time of cutting, consequently the cutting chip 4b naturally drops down following lifting the cut piece 4a. As the result, removal work of the cutting chips 4b is facilitated.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a section retrieval method for retrieving multiple sections at once divided into a plurality of sections in two horizontal fir MA directions, and a retrieval device used therefor.

For example, when producing large quantities of containers made of heat-melting polymers such as expanded polystyrene, conventionally a large number of container recesses 2 are formed as shown in FIG. First, a plate-shaped polymer 4 is formed, and a plurality of sheets of this are stacked on top of 6, and a heated heating wire 8 is pressed on top of the plate-shaped polymer 4.
As shown in FIG. 9, the wire rod 8 was divided into a plurality of pieces in two horizontal and vertical directions to obtain sections 4a. In addition, Section 8.9
In the figure, the heating wire 8 is only placed in a direction perpendicular to the plane of the paper, but in reality, it is placed at a position slightly away from the heating wire 8 in the vertical direction and parallel to the heating wire 8 in the perpendicular direction. A plurality of elongated heating wires are arranged in a pattern η, and by lowering them in conjunction with each other, the polymer 4 can be divided into a plurality of pieces in the form of basic grids in two horizontal directions.

The sections 4a thus obtained need to be transported to a predetermined storage location, but heretofore, each section 4a has been manually taken out from above the lower die 6.

However, the work of manually taking out each section 4a from the lower mold 6 is complicated and takes a long time, which becomes a bottleneck in the work process when producing containers made of each section 4a on the OSE. was. Further, when cutting the plate-shaped polymer 4, chips 4b are generated around the periphery, and it is necessary to remove the chips 4b from the lower die 6.
Conventionally, this work was also done by hand, which resulted in the inconvenience that the work was complicated.

The present invention was made in order to eliminate the inconveniences associated with the above-mentioned prior art at once, and it automatically multiplexes sections that have been divided into two horizontal and vertical directions at once. A first object of the present invention is to provide a method for collecting a section, which makes it possible to take out the section and facilitate the removal of the section.

A second object of the present invention is to provide a take-out device suitable for carrying out the above-described take-out method.

In order to achieve the first objective, the section retrieval method according to the present invention is such that the section retrieval method according to the present invention is such that a section is cut in either the vertical or horizontal directions below the cutting line between the sections divided into a plurality of horizontally vertical and horizontal directions. A fork-like protrusion wider than the distance between the sections is inserted from the direction, and then the fork body on which the fork-like protrusion is formed is moved upward to lift the plurality of sections, and these sections are inserted into the fork body. It is characterized by being transported by

Further, the retrieval device according to the present invention is inserted into a lower part of a cutting line between sections divided into a plurality of sections in two horizontal directions, vertically and horizontally, from either one of the longitudinal and lateral directions, and a plurality of sections having a width wider than the distance between the sections. a fork body having a fork-like protrusion formed therein; a reciprocating means for reciprocating the fork body along the longitudinal direction of the fork-like protrusion; and a vertical movement means for vertically moving the fork body. It is characterized by comprising the following.

According to the section retrieval method and retrieval device according to the present invention, even if the section is divided into a plurality of horizontally vertical and horizontal directions, a fork-like protrusion is formed at the bottom of the cutting line from one of the two horizontal and vertical directions. By inserting the section, lifting and moving the fork body with the fork-like protrusion formed therein, all the cut sections can be automatically transferred to a predetermined location I\. Moreover, since the chips generated during cutting cannot be fully held by the fork-shaped protrusion, they can be automatically dropped, making it easier to remove the chips.

Nine scallops and five scallops Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

1 to 4 are cross-sectional views showing a removal method according to an embodiment of the present invention, FIG. 5 is a front view of a cutting device used in an embodiment of the present invention, and FIG. FIG. 7, a side view of such a take-out device, is a plan view of essential parts of a fork body used in the same device, and members common to those shown in FIGS. 4 and 5 are given the same reference numerals.

The method of taking out a section according to an embodiment of the present invention shown in FIGS. 1 to 4 is a method for producing multiple containers made of a thermofusible polymer. In this embodiment, first, the container recess 2 is First, a large number of plate-shaped heat-melting polymers 4 are formed. The hot-melt polymers to be cut include polystyrene,
In addition to polyethylene, polyvinyl chloride, foams thereof, or other synthetic resins, other heat-melting polymers such as rubber and fibers can be used.

Next, a large number of plate-shaped thermofusible polymers 4 are stacked on the lower die 6 (in FIG. 1, the overlapped polymers are omitted in the middle), and the lower die 6 is made of plastic, Preferably composed of an insulating material such as wood, ceramic, etc., and polymer 4
It has a convex portion 7 that matches the surface shape of. Further, in the lower mold 6, a heating wire 8 that is heated by electricity is attached to a polymer 4.
Lower cutting grooves 10 are formed at the lower part to be arranged at predetermined intervals.

Next, the upper mold 12 is lowered in the direction of the lower mold 6, and the superimposed polymers 4 are pressed from above with a constant pressure, and these polymers 4 are fixed between the upper mold 12 and the lower mold 6. do. Upper mold 1
Like the lower mold 6, the mold 2 is preferably made of an insulating material and has a recess 14 that matches the surface shape of the polymer 4. In addition, a cutting groove 16 is formed in this mold 12 so that the heating wire 8 placed in the cutting groove 10 of the lower mold 6 moves upward and is accommodated in the upper mold 12. . This is because the upper mold 12 and the lower mold 6 are made of an insulating material to effectively prevent the heating wire 8 from being electrically short-circuited.

Next, as shown in FIG. 2, the heating wires 8 arranged at approximately equal intervals are energized and heated.
are simultaneously moved in the direction of the upper mold 12.

At this time, since the heated wire rod 8 is pressed, the superimposed polymer 4 is partially melted along the wire rod 8, and is accurately and easily cut into a large number of pieces 4a in a predetermined shape. . In Fig. 1.2, the heating wire 8 is only placed in a direction perpendicular to the plane of the paper, but in reality, the heating wire 8 is placed at a position slightly curved downward in the vertical direction. A plurality of heating wires extending in parallel with the wire 8 are arranged, and by moving upward in conjunction with each other, the polymer 4 can be divided into a plurality of pieces in two horizontal and vertical directions in the shape of a base pattern. It has become.

A specific cutting device for performing such cutting is shown in FIG. 5, for example.

A cutting device 20 shown in FIG. 5 includes a lower mold 6 and an upper mold 12 preferably made of an insulating material, and a heating wire 8 that is heated by electricity. These lower mold 6, upper mold 12, and heating wire 8 are members similar to those shown in FIG. 1.2.

The heating wire 8 is held by a wire holding frame 21 .

The wire holding frame 21 is vertically movable along guide pins 22. Before placing the polymer 4 (not shown in FIG. 3) on the lower die 6, the wire holding frame 21 is configured to hold the lower die 61p so that the heating wire 8 is accommodated in the cutting groove 10. ! The vertical movement of the 0w& material holding frame, which is preferably moved downward to l, is controlled by a drive motor 23.

Further, the upper die 12 is also movable up and down with respect to the lower die 6 along the guide bin 22. The upper die 12 is moved up and down by a lifting cylinder 24 and a balancing cylinder 25.

In order to automatically take out the sections 4a that have been cut into a plurality of pieces in the horizontal and vertical directions, for example, in the shape of a base opening, from above the lower mold 6 using such a cutting device 20, first, the state shown in FIG. , the upper mold 12 is moved upward together with the heating wire 8.

Next, as shown in FIG. 3, the fork-shaped protrusion 30 is positioned at the bottom of the cut fa4C between each section 4a from either the horizontal direction (in FIG. 3, the direction perpendicular to the paper surface). It is first inserted into the lower cutting bucket 10. As shown in FIG. 7, for example, the fork-shaped projections 30 are formed to project approximately parallel to the ends of the fork body 31 at predetermined intervals, and are wider than the distance t between the sections 48 (see FIG. 3). It has a cross-sectional shape of However, if the cross-sectional width of the fork-shaped protrusion 30 is not narrower than the width of the lower cutting groove 10, it is not preferable because the fork-shaped protrusion 30 cannot be inserted into the groove 10. This does not apply if there is a gap large enough to allow the fork-shaped protrusion 30 to be inserted between the mold and the lower die 6.

Next, as shown in FIG. 4, when the fork body on which the fork-shaped protrusion 30 is formed is moved upward, it
All the sections 4a cut in the direction can be lifted from the lower die 6. Moreover, at that time, the chips 4b on the periphery
Since the chips 4b can be easily dropped, the removal work of the chips 4b is also facilitated.

Thereafter, by moving the fork body on which the fork-shaped protrusion 30 is formed in the horizontal direction, a plurality of sections 4a can be transported to a predetermined location at once.

Note that the extraction method according to the present invention is not limited to the above-described embodiments, and can be variously modified within the scope of the present invention.

For example, in the above-mentioned embodiment, a method for taking out the section 4a of the polymer 4 cut by a heating wire was explained, but the present invention is not limited to this, and the present invention is not limited to this. This method can be applied to the case where a plurality of sections cut in two directions are taken out at the same time. Further, according to the present invention, the material of the section is not limited to a thermofusible polymer;
Other materials may also be used.

Furthermore, the shape before being cut into sections is not limited to a plate shape.
Other shapes may also be used, and in the method of the present invention,
This method can be applied not only to the case of taking out stacked plate-shaped sections 4a but also to the case of taking out a single-layer section 4a.

Next, a take-out device suitable for carrying out the method of the present invention will be described based on the embodiment shown in FIG.

The take-out device 0!40 shown in FIG. 6 is installed on the side of the cutting device 20. This take-out device 40 is equipped with a fork body 31 as shown in FIG. 7 mentioned above. The fork body 31 is mounted in a fixed φ-pull 32, and is movable forward and backward in the direction of arrow A or C by a pressure cylinder or a motor as reciprocating means. When the fork body 31 moves in the direction of arrow A, the fork-like protrusion 30 formed thereon is inserted into the lower cutting groove 10 formed in the lower mold 6 so as to extend in the longitudinal direction thereof. It looks like this.

Further, in order to move the fork body 31 up and down in the directions of arrows B and D, the take-out device 40 is equipped with a pressure cylinder 33 and a vertical movement guide 34 as vertical movement means.

In this way, the fork body 31 is moved from arrow A to
The plurality of sections 4a placed on the lower mold 6 can be transferred onto the fixed table 32 at the same time by sequentially moving in directions B→C→D.

According to such a take-out device 40, the above-described method of the present invention can be carried out conveniently. Note that this take-out device 40 can also be used to automatically place the object to be cut, such as the polymer 4 before cutting, on the bottom 6, which also contributes to the automation of the work process.

According to the retrieval method and retrieval device according to the present invention, even if the section is divided into a plurality of horizontally vertical and horizontal directions, it is possible to remove the section from one of the vertical and horizontal directions to the bottom of the cutting line. By inserting the fork-like protrusion, lifting up and moving the fork body on which the fork-like protrusion is formed, it becomes possible to automatically transport all cut sections to predetermined locations. Moreover, since the chips generated during cutting cannot be fully held by the fork-shaped protrusion, they can be automatically dropped, making it easier to remove the chips.
