Description

  The present invention relates to a guide shooter used when packing a silicon material in a bag and a method for packing the silicon material using the guide shooter.

Conventionally, the Siemens method, which is known as a method for producing polycrystalline silicon, supplies a raw material gas containing chlorosilane gas and hydrogen gas into a reaction furnace, contacts a heated silicon core rod, and supplies the raw material gas on the surface thereof. This is a technique for depositing polycrystalline silicon in a columnar shape by thermal decomposition and hydrogen reduction.
The polycrystalline silicon is cut into short pieces or crushed into blocks, washed and dried, then packed and provided as a material for manufacturing single crystal silicon. For example, as described in Patent Document 1, the silicon material is packaged by separating the silicon material according to size and then packing the silicon material into a bag made of polyethylene resin or the like for each size. It is stored in a cardboard box.

JP 2006-143552 A

In general, a partition plate is provided in a lattice shape in a box, and one piece of silicon material packed in a bag is stored in each storage space partitioned into rectangles by the partition plate. In this case, quality deterioration may occur due to friction between the silicon materials in the bag or friction between the silicon material and the bag due to vibration during transportation. For this reason, there is a method of packing cushioning material between the partition plate so that the silicon material does not move, but it takes time and effort to pack the buffering material, and if the buffering material is disposed of, the load on the environment also increases. It becomes. When the cushioning material or the like is not packed, the gap (interval) between the silicon material and the partition plate is preferably as small as possible for the above reason.
However, if the gap is small, the bag may be rubbed by the upper end of the partition plate when the silicon material packed in the bag is stored in each storage space, and the bag may be broken. In particular, since a short product called a cut rod obtained by cutting polycrystalline silicon into a short length is heavy to about 5 to 10 kg, there is a problem that the impact when hitting the upper end of the partition plate is large and is easily damaged.

  In this case, it may be possible to reduce friction by covering the upper end of the partition plate with a sheet or the like, but the work of attaching and removing the sheet is troublesome, and the sheet is dragged by the silicon material during the packing operation. There is a risk of getting caught in the box. Usually, corrugated cardboard is sometimes used as a shipping box for silicon materials, but because of the above-mentioned environmental load problems, so-called returnable boxes that reuse shipping boxes are used. The number of cases is increasing, and after the silicon material is transported, it is disassembled and sent back. However, if the sheet or the like is mixed in at that time, dismantling work is hindered. In addition, in the case of returnable boxes, there are cases where hard partition plates such as resin are used from the viewpoint of durability for repeated use, compared to the case where cardboard boxes and partition plates are used, the above silicon materials When the bag is stored in the storage space, there is a problem that there is a high possibility that the bag will be torn.

  The present invention has been made in view of such circumstances, and provides a guide shooter that can be boxed without causing breakage or the like in the bag and that is easy to handle, and a method for packing a silicon material using the guide shooter The purpose is to do.

  The guide shooter of the present invention is a guide shooter that guides when storing the packaged silicon material from the rectangular opening in the storage space of the box with the upper side open, and the storage space Inserted into the inner side wall of the side wall, and an insertion frame part formed by connecting a plurality of plate-like parts along the inner periphery of these side walls, and extending upward to the upper end of each plate-like part of the insertion frame part. And a plurality of guide pieces that are inclined in a direction gradually expanding from the insertion frame portion as it goes upward, and at least an upper portion of the plate-like portion can be expanded outward in the insertion frame portion. It is characterized in that a flexible stretchable part is provided.

  The silicon material packaging method using the guide shooter is such that the insertion frame portion of the guide shooter is inserted into the storage space, and the guide piece extends over the side wall. The guide shooter is pulled out from the storage space after storing the silicon material in a state of being packed in the insertion frame portion from the inside.

That is, the insertion frame portion of the guide shooter is inserted into the storage space from the opening of the box body, and the guide piece is projected outwardly above the side wall, and the silicon material packed in this state is placed inside the insertion frame portion. When stored, the silicon material is stored while sliding along the inner surface of the insertion frame portion from the inner surface of the guide piece. At this time, since the guide piece extends above the side wall of the box, the bag covering the silicon material does not contact the upper end of the side wall of the box, and the guide piece extends from the guide piece to the continuous inner surface of the plate-like portion. It is guided smoothly along.
In this case, the expansion / contraction part is provided in the plate-shaped part that constitutes the insertion frame part, so that the silicon material is accommodated while the upper side of the insertion frame part is widened when the both ends of the silicon material are accommodated by hand. Therefore, the silicon material can be stored with the hand supported to the end.
After the silicon material is stored, if the guide shooter is pulled up, the insertion frame portion interposed between the bag and the side wall can be easily pulled out.

In the guide shooter of the present invention, the insertion frame portion may be provided with a hook portion that is locked to the upper end portion of the side wall when the insertion frame portion is disposed in the storage space.
Since the hook portion is locked to the upper end portion of the side wall, the insertion frame portion can be reliably prevented from being dragged into the silicon material. For this reason, the height of the insertion frame portion can be shortened, and it is not necessary to insert the frame deeply into the storage space, thereby further improving the handleability.

  According to the guide shooter and the packaging method of the present invention, the guide frame of the guide shooter projects over the side wall by disposing the insertion frame portion inside the side wall constituting the opening. The packed silicon material can be stored in the insertion frame while being guided by the inner surface of the guide piece, and the bag can be stored smoothly without being rubbed against the upper end of the side wall of the opening. Further, after the storage, if the guide shooter is pulled upward, only the silicon material can be stored in the storage space, and the storage work can be performed smoothly and reliably, and the workability can be remarkably improved.

It is a principal part enlarged plan view which shows 4th Embodiment of the guide shooter which concerns on this invention.

Hereinafter, an embodiment of a guide shooter of the present invention will be described with reference to the drawings.
The storage container 1 will be described in advance. As shown in FIG. 5, the storage container 1 includes a plurality of flat plates 3 that divide the interior into a plurality of upper and lower stages in a box 2 that is open upward. In addition, a grid-like partition plate 5 that partitions the space between the flat plates 3 into a plurality of storage spaces 4 is provided. Of the four side wall members 6a and 6b constituting the box body 2, the pair of side wall members 6a and 6a facing each other is formed of a single member, and the other pair of side wall members 6b and 6b are The split member 7 in the upper half can be attached to and detached from the lower half at a substantially intermediate position in the height direction. A lid (not shown) is attached to the upper end of the box 2.

  The partition plate 5 is made of, for example, polypropylene (PP), and includes a first partition plate 8 and a second partition plate 9 that are assembled in an orthogonal state as shown in FIG. While forming in a rectangular parallelepiped shape, the opening 4a at the upper end is formed in a rectangular shape. The height of these partition plates 8 and 9 is slightly higher than the packaged silicon material 10. Hereinafter, when the two partition plates are described separately, the first partition plate 8 and the second partition plate 9 are used. When these are not distinguished from each other, the partition plate 5 is used.

  The first partition plate 8 is provided along the short side direction of the storage space 4 so as to face a cut end surface 10a of the silicon material 10 described later, and from the diameter of the silicon material 10 packed in the bag 11 Also, the slits 12 are provided at slightly longer intervals. The slit 12 is formed vertically from the upper end of the first partition plate 8 and is preferably formed below the intermediate position in the height direction of the first partition plate 8.

  The second partition plate 9 is provided along the long side direction of the storage space 4, and is opposed to the side surface 10 b in the length direction of the silicon material 10, and the length of the silicon material 10 is increased in the length direction. The slits 13 are provided with an appropriate interval shorter than that. The slits 13 are vertically formed from the lower end of the second partition plate 9 to almost the middle in the height direction. By using a plurality of these slits 13, the silicon material 10 packed in the bag 11 can be used. A storage space 4 slightly longer than the length can be formed.

  In this case, since the slit 12 is formed in the first partition plate 8 from the upper end, a rectangular bending piece 14 is formed between the two adjacent slits 12. As shown by the arrow in FIG. 6, the bending piece 14 can be bent in the length direction of the storage space 4. At that time, as described above, since the slit 12 of the first partition plate 8 is formed below the intermediate position in the height direction, the flexure piece 14 is at least half the height of the partition plate 5. Formed.

The flat plate 3 is made of, for example, polypropylene (PP), is formed in an area slightly smaller than the bottom area of the box 2, and is disposed above and below the partition plate 5.
And on this flat plate 3, the 1st partition plate 8 and the 2nd partition plate 9 are integrated in a grid | lattice form so that the slit 12 of the 1st partition plate 8 and the slit 13 of the 2nd partition plate 9 may be combined. Thus, a plurality of storage spaces 4 partitioned by the first partition plate 8 and the second partition plate 9 are formed on the flat plate 3, and each storage space 4 has its opening. The part 4a is formed in a rectangular parallelepiped shape having a rectangular shape.

The silicon material 10 stored in each storage space 4 thus formed is stored in a bag 11 made of polyethylene (PE) as shown in FIG. In order to prevent the contamination of the silicon material 10, the bag 11 is provided at least twice, and more preferably triple.
In this case, in the packing form shown in FIG. 7A, the innermost bag 11a is sealed by the seal portion 15 at the edge of the end surface 10a side of the silicon material 9, and the outer bag (second layer) of the bag 11a is sealed. The bag 11b is sealed by the seal portion 15 at the edge on the side surface 10b side of the silicon material 10 whose direction is changed by 90 ° from the innermost bag 11a. The outermost bag (third bag) 11c is sealed on the side surface together with the second bag 11b.

Further, in the packing form shown in FIG. 7B, the innermost bag 11a is sealed by the seal portion 15 at the edge on the end face 10a side of the silicon material 10 as in the case of FIG. The second outer bag 11b and the outermost third bag 11c of 11a are also sealed together by the seal portion 15 at the edge of the silicon material 10 on the end face 10a side.
Due to such a triple structure packing, even if the bag 11 is torn in a process other than the packing operation of the silicon material 10 into the storage container 1, the silicon material 10 is reliably prevented from being contaminated. . In this way, the silicon material 10 stored in the bag 11 is referred to as a silicon package 16.

  The guide shooter 21 used when the silicon package 16 is stored in the storage container 1 is made of a hard resin having a small surface friction coefficient, for example, polytetrafluoroethylene (PTFE), and has a thickness of 2 to 3 mm. As shown in FIGS. 1 to 3, an insertion frame portion 22 inserted into the storage space 4 and a plurality extending upward from the upper end of the insertion frame portion 22 are configured. The guide piece 23 is provided.

The insertion frame portion 22 is configured such that the short plate-like portion 24 and the long plate-like portion 25 are connected along the inner periphery of the side wall (partition plate 5) constituting the storage space 4. It is formed in a rectangular tube frame shape having a flat area slightly smaller than 4.
In addition, at the four corners of the insertion frame portion 22, an expansion / contraction portion 26 that can be bent in the direction of opening the upper half of each plate-like portion 24, 25 is formed. In the present embodiment, the expansion / contraction portions 26 are formed by forming cuts in the upper half of the connecting portions of the plate-like portions 24 and 25, and the plate-like portions 24 and 25 are within the range of the cuts. The upper half can be extended outward.
The guide piece 23 is connected to the upper ends of the plate-like portions 24 and 25 of the insertion frame portion 22 so as to extend upward, and is provided so as to incline in a direction gradually expanding from the insertion frame portion 22 toward the upper side. Yes. In addition, the inner surface of the connection part of each guide piece 23 and each plate-like part 24 and 25 of the insertion frame part 22 has a slightly curved shape.

Next, a method for storing the silicon packages 16 one by one in the storage space 4 of the storage container 1 will be described while using the guide shooter 21 configured as described above.
As shown in FIG. 3, when the insertion frame portion 22 of the guide shooter 21 is inserted into the storage space 4, the guide pieces 23 connected to the upper ends of the plate-like portions 24 and 25 of the insertion frame portion 22 are stored in the storage space. 4 is overhanging above the side wall (partition plate 5) that constitutes 4.

The silicon package 16 is normally handled while supporting the both end surfaces 10a with hands. Then, the whole of the silicon package 16 is tilted with both hands supported, and the one end face 10 a side is inserted into the insertion frame portion 22 while being along the guide piece 23 of the guide shooter 21.
At this time, as shown in FIG. 4, since the end portion of the silicon package 16 is inserted into the insertion frame portion 22 including the hand H, the plate-like portion 24 of the insertion frame portion 22 is spread outward. The upper half of the plate-like portion 24 is formed with a cut-out portion 26 by cutting, and the upper half of the partition plate 8 located on the back of the plate-like portion 24 is also formed as a flexure piece 14 with the cut-off 12, so these are shown in FIG. As indicated by the arrow, the silicon package 16 is pushed outward and can be stored in the storage space 4 together with the hand H.

Subsequently, the silicon package 16 is guided into the insertion frame 22 so as to slide along the guide piece 23 while lowering the other end of the silicon package 16. At this time, the hand H supporting this end is inserted into the insertion frame portion 22 together with the silicon package 16, but in the same manner, the plate-like portion 24 and the flexure piece 14 of the partition plate 8 open outward. Accordingly, the silicon package 16 can be inserted into the insertion frame portion 22 while being supported by the hand H to the end.
Further, since the guide piece 23 and the insertion frame portion 22 are integrally formed, the silicon package 16 can be smoothly guided into the insertion frame portion 22 along the guide piece 23. Therefore, it is possible to reliably prevent the bag 11 of the silicon package 16 from being damaged such as being rubbed against the upper end of the partition plate 5 and broken.
After the silicon package 16 is stored in the storage space 4, the guide shooter 21 can be pulled out from the space between the silicon package 16 and the partition plate 5 by removing the guide shooter 21 upward.
In this way, while using the guide shooter 21, the silicon package 16 is sequentially stored in the storage space 4, and finally the storage container 1 is covered and the packing operation is completed.

FIG. 8 shows a second embodiment of the guide shooter of the present invention. The guide shooter 31 has a hook portion 32 fixed to the outer surface of the insertion frame portion 22, which is locked to the upper end portion of the partition plate 5. When the insertion frame portion 22 is inserted into the storage space 4, The guide shooter 31 can be positioned and fixed by hooking the hook portion 32 to the upper end of the partition plate 5.
Accordingly, the downward movement of the guide shooter 31 is restricted, and the guide shooter 31 is prevented from being dragged into the storage space 4 together with the silicon package 16 when the silicon package 16 is stored. Is done. For this reason, the insertion frame portion 22 can be formed short enough to be inserted only into the upper end portion of the storage space 4, for example, half the diameter of the silicon material 10, and the silicon package 16 can be stored. The removal of the guide shooter 31 after this can be facilitated.
In addition, the hook part 32 should just be provided in the outer surface of the insertion frame part 22, and may be provided in any of a four corner part and a perimeter.
In the following embodiments, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

FIG. 9 shows a third embodiment of the guide shooter according to the present invention.
In the guide shooter of the third embodiment, each plate-like portion 24, 25 of the insertion frame portion 41 is formed one by one, and these are connected by a bellows-like stretchable portion 42. Not only the upper side of the insertion frame part 41 but the whole can be expanded outward. In this case, as shown in FIG. 9 (a), the expansion / contraction part 42 may be bent so as to constitute the corners of both plate-like parts 24 and 25, or as shown in FIG. 9 (b), The expansion / contraction part 42 may be provided so as to extend the plate-like part 25. In either case, both the plate-like portions 24 and 25 can be spread outward, and the operation of storing the silicon package 16 can be further facilitated.

  FIG. 10 shows a fourth embodiment of the guide shooter according to the present invention, and in this fourth embodiment, the stretchable portion 46 of the insertion frame portion 45 is formed of a stretchable material such as rubber. The mounting structure is the same as that of the third embodiment, and as shown in FIG. 10 (a), it may be a stretchable portion 46 that is bent so as to constitute the corners of both plate-like portions 24, 25, As shown in FIG. 10B, an extendable part 46 may be provided so as to extend any plate-like part 25.

Note that the present invention is not limited to the above-described embodiment, and various modifications other than those described above can be added without departing from the spirit of the present invention.
For example, in the above-described embodiment, the insertion frame portion of the guide shooter is formed by at least one short plate-like portion 24 and two long plate-like portions 25, and one of the four sides is open. There may be three guide pieces corresponding to these plate-like portions.

In the above embodiments, the storage space partitioned by the partition plate has been described. Most of the storage space is partitioned by a partition plate, but in the outer peripheral portion, a part of the side wall portion is constituted by the side wall portion of the box. In this case, a phenomenon occurs in which the bag of the silicon package is rubbed at the upper end of the side wall member 6a and the dividing member 7 of the box or at the upper end of the side wall member 6b after the dividing member 7 is removed. The guide shooter of this embodiment is also effective when stored in these positions. The side wall in the present invention refers to not only a partition plate but also a side wall member or a division member of a box.
Moreover, although the example which accommodated the silicon material in the some bag was shown as a silicon | silicone package, what was accommodated in one bag is not excluded.
