Description

Technical Field

[0001] This invention relates to a fixture for manufacturing polycrystalline silicon packages and a method for manufacturing polycrystalline silicon packages. Background Technology

[0002] Polycrystalline silicon, used as a raw material for silicon semiconductors and solar cells, is manufactured in rod form, then cut and crushed for use as raw material, thus processing it into block polycrystalline silicon of a predetermined size. This block polycrystalline silicon is then bagged and boxed in predetermined quantities for shipment. Traditionally, as shown in Patent Document 1, the bagging and boxing processes are generally performed manually. In the future, it is desirable to automate these bagging and boxing operations to improve operational efficiency and save labor.

[0005] Patent Document 1: Japanese Patent Publication No. 2017-512159 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] However, the aforementioned automated packing method has the following problems. The irregular shape of block polysilicon, with angled fracture surfaces and sharp edges, makes the bags containing it prone to tearing. Furthermore, when the top of a bag containing multiple block polysilicon pieces is lifted, the individual pieces inside the bag shift downwards, causing the bag's width to widen locally. Therefore, during packing, the bags are likely to come into contact with box dividers or other objects, increasing the risk of tearing at the contact points.

[0008] The present invention was developed in view of the aforementioned problem, and its purpose is to prevent local bulging of the containment bag during the process of lifting the bagged polycrystalline silicon and placing it into a predetermined position, thereby accurately placing the containment bag into a predetermined space.

[0009] Technical solutions for solving the problem

[0010] To address the aforementioned problem, one aspect of the present invention relates to a clamp comprising: a side body forming an insertion space for inserting and accommodating a polysilicon receiving bag; a lifting portion disposed on the side body for lifting the side body; and a receiving tray detachably disposed at the bottom of the side body for supporting the receiving bag; wherein when the side body is lifted and the receiving tray detaches from the bottom of the side body, an opening is formed at the bottom of the side body, and when the receiving bag is placed into the receiving space containing the receiving bag from above, the opening forms a placement path of the receiving bag from the insertion space to the receiving space.

[0011] To address the aforementioned problem, one aspect of the present invention relates to a method for manufacturing a polycrystalline silicon package, which uses the clamp to insert the receiving bag into a box having the receiving space to obtain a polycrystalline silicon package. The method includes: a lifting step, in which the receiving bag inserted in the clamp is lifted together with the clamp; and a placing step, in which the lifted clamp and the receiving bag are moved above the predetermined receiving space, and the receiving bag is placed into the receiving space from above the receiving space.

[0012] Invention Effects

[0013] According to one aspect of the invention, local bulging of the containment bag can be prevented during the process of lifting the bagged polysilicon and placing it into a predetermined position, thereby accurately placing the containment bag into a predetermined space.

[0023] [Implementation Method 1]

[0024] <Brief Structure of a Polycrystalline Silicon Packaging Manufacturing Apparatus>

[0025] based on Figure 1 An example of the configuration of the manufacturing apparatus 100 for polycrystalline silicon package G1 will be described. Figure 1 This is a perspective view showing the configuration of a manufacturing apparatus 100 for a polysilicon package G1 according to Embodiment 1 of the present invention. The manufacturing apparatus 100 is an apparatus for manufacturing a polysilicon package G1 by packaging polysilicon filler FI. The polysilicon filler FI is obtained by sealing a receiving bag B1 filled with polysilicon S1.

[0026] like Figure 1 As shown, the manufacturing apparatus 100 includes conveyors C1 to C4, a packing device 1, and locations A1 to A4.

[0027] On conveyor C1, a receiving bag B1 is first inserted into the inner insertion space 12 of the receiving box 10. Then, a predetermined amount of polysilicon S1 is filled into the receiving bag B1. Furthermore, the receiving bag B1 filled with polysilicon S1 is sealed to form polysilicon filler FI. Then, the receiving box 10 containing the polysilicon filler FI that has passed various inspections is transported to the packing device 1 by conveyor C1.

[0028] The packing device 1 is used to contain the polysilicon filler FI of the housing 10 into the box BX, and the box-making machine SK is used to manufacture the box BX. The packing device 1 and the box-making machine SK will be described in detail later.

[0029] Conveyor C2 branches off from conveyor C1. Conveyor C2 transports the empty container 10, from which the polysilicon filler FI has been removed by the packaging device 1, to the vicinity of the starting point of the manufacturing device 100 for the polysilicon package G1.

[0030] At location A1, the box BX containing the polysilicon filler FI is automatically or manually sealed to complete the polysilicon package G1. Conveyor C4 transports the polysilicon package G1 to the outside of the manufacturing unit 100. The polysilicon package G1, transported by conveyor C4 to the outside of the manufacturing unit 100, is then placed on a pallet by operators for handling.

[0031] <Regarding issues with packaging polysilicon fillers>

[0032] Here, when the polysilicon filler FI inserted in the receiving box 10 is received into the box BX, the packing device 1 lifts the polysilicon filler FI and throws it from above the box BX into the receiving space 20 formed inside the box BX.

[0033] Polycrystalline silicon S1 is formed by cutting and crushing polycrystalline silicon manufactured in rod shape for use as raw material, thereby forming block polycrystalline silicon S1 of a predetermined size. Therefore, when the multiple block polycrystalline silicon S1 placed in the receiving bag B1 are lifted by holding the upper part of the receiving bag B1, their state is as follows. Figure 2 As shown.

[0034] Figure 2 This diagram illustrates the collapse of blocky polysilicon S1 within the receiving bag B1 of the polysilicon filler FI. State 1001 shows the state before the polysilicon filler FI is lifted, and state 1002 shows the state after the polysilicon filler FI is lifted. When the polysilicon filler FI is lifted, each blocky polysilicon S1 moves within the receiving bag B1 in the direction of the arrow shown in state 1001. As shown in state 1002, the width of the receiving bag B1 locally bulges.

[0035] Furthermore, the blocky polycrystalline silicon S1 consists of irregularly shaped fragments with angular fracture surfaces and sharp corners. Therefore, the corners of the polycrystalline silicon filler FI may become lodged within the box BX, forming the partition PR that creates the containing space 20, or on the side of the box BX, causing holes or tears in the bag where it is stuck. This is a unique risk of bag breakage during the packaging of polycrystalline silicon S1.

[0036] Therefore, as Figure 3 As shown, the container 10 (clamp) of the present invention includes a side body 11, a lifting part 13, and a receiving plate 15. The side body 11 forms an insertion space 12 for inserting a container bag B1 filled with polysilicon S1. The lifting part 13 is disposed on the side body 11 to lift the side body 11. The receiving plate 15 is detachably disposed on the bottom 11a of the side body 11 for supporting the container bag B1. Furthermore, after the side body 11 is lifted, the receiving plate 15 separates from the bottom 11a of the side body 11, forming an opening OP at the bottom 11a of the side body 11. Further, when the container bag B1 is placed into the receiving space 20 of the container bag B1 from above, as... Figure 7 As shown, the opening OP forms a delivery path 30 for the receiving bag B1 from the inner insertion space 12 to the receiving space 20.

[0037] Therefore, during the process of lifting the bagged polycrystalline silicon S1 and placing it into the designated position, local bulging of the receiving bag B1 can be prevented, thus enabling the receiving bag B1 to be accurately placed into the designated space. A detailed explanation follows.

[0038] <Container>

[0039] based on Figure 3 and Figure 4 The container 10 will be described. Figure 3 This is a perspective view showing an example of the configuration of the container 10 used in the manufacturing apparatus 100. Figure 3The perspective view 2001 shows the receiving box 10 in which the side body 11 and the receiving plate 15 are integrated. Furthermore, Figure 3 The three-dimensional diagram 2002 represents the side view of body 11. Figure 3 The 3D diagram 2003 represents receiving plate 15. Figure 4 yes Figure 3 AA cross-sectional view. Additionally, in Figures 2 to 9 In the description of the container 10 in which the side body 11 and the receiving plate 15 are integrated, the direction of the side body 11 toward the receiving plate 15 is set to downward, and the direction of the receiving plate 15 toward the side body 11 is set to upward.

[0040] like Figure 3 As shown, the side body 11 forms an intercalation space 12 for intercalating polysilicon filler FI (a receiving bag B1 filled with polysilicon S1). The side body 11 is cylindrical, and the intercalation space 12 is formed by surrounding the four faces remaining after removing the top and bottom faces from the six faces of a generally rectangular prism. The opposing faces of the four faces of the side body 11 are generally the same and generally parallel.

[0041] Furthermore, the opening OP is contained within a cross-section formed by cutting the receiving space 20 with a plane approximately parallel to the horizontal plane. Therefore, when polysilicon filler FI is placed into the receiving space 20, the polysilicon filler FI will not come into contact with partitions or the like forming the receiving space 20. Thus, for example, when polysilicon filler FI is loaded into the box BX forming the receiving space 20, the corners of the polysilicon filler FI can be prevented from hitting partitions or the like, thus avoiding the situation where the receiving bag B1 ruptures.

[0042] The side body 11 has a lifting portion 13 disposed on the upper part of a set of opposing surfaces so as to lift the side body 11. The lifting portion 13 has an outwardly protruding shape and is configured to extend along the upper edge of the disposed surface.

[0043] The receiving plate 15 is a generally rectangular plate-shaped component. The receiving plate 15 has a protrusion 16 and a sidewall 17. The protrusion 16 is arranged along both ends of the short side of the receiving plate 15 so as to protrude outward. On the upper surface of the receiving plate 15, the sidewall 17 is arranged along the two ends in a manner perpendicular to the upper surface of the receiving plate 15.

[0044] like Figure 3 and Figure 4 As shown, the receiving plate 15 is detachably disposed at the bottom 11a of the side body 11 for supporting the polysilicon filler FI.

[0045] In the manufacturing apparatus 100, when the receiving box 10 moves on the conveyor, the side body 11 is embedded between the opposing side walls 17 of the receiving plate 15, and the side body 11 moves integrally with the receiving plate 15. Furthermore, when the receiving box 10 is lifted, the protrusion 16 is fixed at location A2 by the baffle 40 (described later) etc. (see...) Figure 1 and Figure 8 The lifting part 13 is pulled upward. As a result, the side body 11 separates from the receiving plate 15, and only the side body 11 is lifted.

[0046] Furthermore, the location of the receiving plate 15 is not limited to... Figure 3 and Figure 4 The position shown is at the same height as the lower end 11b of the side body 11. For example, as... Figure 5 As shown, the receiving plate 15 can also be located on the upper end 11c side above the lower end 11b of the side body 11 at the same height. Figure 5 This is a cross-sectional view of container 10A, representing another example of container 10.

[0047] Consider the case where the receiving tray 15 is located at the upper end 11c side, above the same height as the lower end 11b of the side body 11. In this case, although not shown, a support portion for supporting the receiving tray 15 can also be provided on the inner surface of the side body 11. For example, the support portion protrudes from the inner surface of the side body 11 and retracts relative to the inner surface of the side body 11, thereby releasing the support for the receiving tray 15. Furthermore, when the receiving box 10 is lifted, the support portion for the receiving tray 15 is released, causing the receiving tray 15 to separate from the side body 11.

[0048] Furthermore, based on Figure 6 Another example of the container 10, container 10B, will be described. Figure 6 This is a diagram representing container 10B. Figure 6 The top view of 2004 is the top view of the housing 10B. Figure 6 The 2005 cross-sectional view is a BB arrow view of the top view of 2004. Figure 6 The side view of 2006 is a side view of the housing 10B. (See image 2006.) Figure 6 As shown, the receiving box 10B includes a receiving tray 15B instead of a receiving tray 15. The receiving tray 15B does not have a side wall 17, but a handle portion 18 is provided on the receiving tray 15B.

[0049] In the receiving box 10B, a groove 19 is formed on the upper surface of the receiving tray 15B, which can be inserted into the side body 11. In this case, in the manufacturing apparatus 100, when the receiving box 10B moves on the conveyor, the side body 11 moves integrally with the receiving tray 15B with the side body 11 inserted into the groove 19. By providing a handle 18 on the receiving tray 15B, operations such as unloading the receiving tray 15B from the conveyor become easier, thereby improving work efficiency.

[0050] The container 10 is preferably made of resin, such as vinyl chloride, polypropylene, polyethylene, polytetrafluoroethylene, polyvinylidene fluoride, etc.

[0051] <Manufacturing Method>

[0052] based on Figure 1 and Figure 7 The manufacturing method of the polycrystalline silicon package according to Embodiment 1 of the present invention will be described. Figure 7 This is a schematic diagram illustrating the operation of the housing 10 and the polysilicon filler FI in the manufacturing method of the polysilicon housing G1 according to Embodiment 1 of the present invention, showing steps 3001 to 3004. Furthermore, in Figure 7 In the diagram, the components of the container 10 are shown in a simplified form. Furthermore, the direction in which the conveyor C1 propels the product is forward, and the opposite direction is described as rearward.

[0053] As described above, in the packaging apparatus 1, the polysilicon filler FI of the housing 10 is contained in the housing BX, and the housing BX is sealed at location A1, thereby manufacturing the polysilicon packaging body G1. Figure 1 As shown, the box BX containing polysilicon filler FI is manufactured by the box-making machine SK. The box-making machine SK lays a cushioning material BU at the bottom of the empty box and embeds partitions PR within the box BX so that one box BX can hold multiple polysilicon fillers FI. In other words, the box-making machine SK creates a receiving space 20 within the box BX to hold the polysilicon filler FI by embedding partitions PR. The box BX with the receiving space 20 is then transported to location A4 by conveyor C3.

[0054] Furthermore, to ensure sufficient storage space 20 to accommodate the polysilicon filler FI, the partition position adjustment operation can be performed on the box BX transported to location A4 before accommodating the polysilicon filler FI. The partition position adjustment operation can be performed, for example, using an extended clamp as described below.

[0055] The extension clamp has a front support and a rear support, and the distance between the front support and the rear support is variable. The extension clamp is inserted into the receiving space 20, causing the front support and the rear support to move away from each other. As a result, the front support contacts the partition PR located in front of the receiving space 20 in the forward direction of the conveyor C1, and the rear support contacts the partition PR located behind the receiving space 20 in the same forward direction.

[0056] Furthermore, when the extended clamp further separates the front support from the rear support, the width of the receiving space 20 along the forward direction is increased. This ensures sufficient receiving space 20 to accommodate the polysilicon filler FI.

[0057] An extension clamp is inserted into the receiving space 20 from above. Furthermore, the extension clamp is configured to the left and right sides of one receiving space 20 relative to its forward direction, ensuring sufficient space 20 to accommodate the polysilicon filler FI. After ensuring sufficient space 20 using the extension clamp, the extension clamp is removed from the receiving space 20 as needed. Additionally, when there are multiple receiving spaces 20, the extension clamp is simultaneously inserted into each receiving space 20 to expand the width of each receiving space 20 to the necessary size.

[0058] The container 10, which contains the polycrystalline silicon filler FI delivered by the conveyor C1, is moved to location A2.

[0059] In the packing device 1, when the container 10 containing the polysilicon filler FI is moved to location A2, as... Figure 7 As shown in step 3001, the polysilicon filler FI inserted in the receiving box 10 is lifted together with the side body 11 (lifting step). In the lifting step, the receiving tray 15 separates from the side body 11 of the receiving box 10, forming an opening OP at the bottom 11a of the side body 11. That is, in the lifting step, only the side body 11 is lifted.

[0060] With the polysilicon filler FI inserted, the lifted side body 11 and the polysilicon filler FI are moved above the designated receiving space 20. By moving the side body 11 above the designated receiving space 20, as shown in step 3002, a delivery path 30 for the polysilicon filler FI from the insertion space 12 to the receiving space 20 is formed through the opening OP. Then, as shown in step 3003, the polysilicon filler FI is delivered from above the receiving space 20 into the receiving space 20 (delivery step).

[0061] As shown in process 3004, the side body 11 after the polysilicon filler FI is applied is embedded again into the receiving plate 15.

[0062] based on Figure 1 and Figures 7-8 The operation of the packing device 1 in processes 3001 to 3004 will be explained. Figure 8 This diagram illustrates the operation of the packing device 1 in steps 3001 to 3004 of the manufacturing method. Figure 8 In the diagram, arrows Y1 and Y4 indicate the vertical movement of the side body 11. Arrows Y2, Y3, Y6-1, Y6-2, and Y7 indicate the horizontal movement of the receiving box 10, the side body 11, or the receiving plate 15. Arrow Y5 indicates the movement of the side body 11 in both the vertical and horizontal directions.

[0063] like Figure 8 As shown, in step 3001, the protrusion 16 of the container 10, which is being transported to location A2, is secured by the baffle 40 of the packing device 1. Next, the packing device 1 lifts the polysilicon filler FI and the lifting portion 13 of the side body 11, which are inserted into the container 10. As a result, the receiving tray 15 separates from the side body 11, and as indicated by arrow Y1, the polysilicon filler FI and the side body 11 are lifted (lifting step). As indicated by arrow Y2, the receiving tray 15 remaining on the conveyor C1 is transported by the conveyor C1 to location A3.

[0064] As indicated by arrow Y3, the polysilicon filler FI and side body 11, which were lifted in step 3001, are moved by the packing device 1 to the upper part of the receiving space 20 of the box BX at location A4. Then, in steps 3002 and 3003, as indicated by arrow Y4, the polysilicon filler FI is placed from above the receiving space 20 into the receiving space 20 (placing step).

[0065] In the delivery process, before delivering the polysilicon filler FI, an additional configuration can be added whereby the upper width of the separator PR is varied so that the polysilicon filler FI does not come into contact with the separator PR. This variable upper width of the separator PR can be achieved, for example, by inserting a pair of claws from above into the receiving space 20 and keeping them horizontally separated. In other words, by having these claws contact the upper part of the separator PR, the upper width of the separator PR can be increased.

[0066] By changing the upper width of the separator PR as described above, even if the side body 11 approaches the separator PR due to the inclusion of polysilicon filler FI during the delivery process, the bottom 11a of the side body 11 (see above) can be prevented from being exposed to the material. Figure 9 The polysilicon filler FI comes into contact with the partition PR. As a result, when the polysilicon filler FI is placed into the receiving space 20, the receiving bag B1 can be prevented from breaking due to the polysilicon filler FI coming into contact with the partition PR. In addition, after the polysilicon filler FI has been placed into the receiving space 20, the above-mentioned pair of claws can be pulled out of the receiving space 20 as needed.

[0067] In process 3004, as shown by arrow Y5, the side body 11, which has been filled with polysilicon filler FI and whose internal space 12 is empty, is embedded by the packing device 1 into the receiving tray 15 that is transported to location A3 by the conveyor C1.

[0068] Then, at location A3, as indicated by arrow Y6-1, the ejection mechanism 41 of the packaging device 1 pushes the protrusion 16 of the receiving tray 15, as indicated by arrow Y6-2, causing the container 10 to move from conveyor C1 to conveyor C2. The container 10, now on conveyor C2, is transported by conveyor C2 to the vicinity of the starting point of the manufacturing apparatus 100 for the polysilicon package G1, as indicated by arrow Y7.

[0069] Furthermore, the orientation of the container 10 being transported by the conveyor is not particularly limited, and the long side of the container 10 can be approximately parallel to the forward direction of the conveyor. In this case, the protrusions 16 are arranged along both ends of the long side of the receiving plate 15, and the ejection mechanism 41 of the packing device 1 pushes the protrusions 16 arranged on the long side of the receiving plate 15 to move the container 10 from the conveyor C1 to the conveyor C2.

[0070] The feeding process is repeated until the containment space 20 formed inside box BX is filled with polysilicon filler FI. When the containment space 20 formed inside box BX is filled with polysilicon filler FI, box BX is transported to location A1 by conveyor C4 and automatically or manually sealed. In this way, polysilicon filler FI is loaded into box BX to obtain polysilicon package G1.

[0071] [Implementation Method 2]

[0072] The following is based on Figure 9 Another embodiment of the present invention will be described. Figure 9 This is a schematic diagram illustrating the manufacturing method of the polysilicon package G1 according to Embodiment 2 of the present invention. Furthermore, for ease of explanation, components having the same function as those described in the above embodiments are labeled with the same symbols, and repeated descriptions are omitted.

[0073] like Figure 9 As shown, compared with the manufacturing method of polysilicon package G1 according to Embodiment 1, the difference of the manufacturing method of polysilicon package G1 according to Embodiment 2 of the present invention is that auxiliary component 50 is used in the delivery process, while other processes are the same.

[0074] The receiving box 10 includes an auxiliary component 50. The auxiliary component 50 guides the polysilicon filler FI from the side body 11 into the receiving space 20. The auxiliary component 50 has a guiding side body 51 on which a first opening 52 and a second opening 53 are formed. The second opening 53 is located opposite to the first opening 52, and its opening area is smaller than that of the first opening 52. The shapes of the first opening 52 and the second opening 53 are not particularly limited and can be circular or quadrilateral.

[0075] During the delivery process, when the side body 11 is lifted and the polysilicon filler FI is delivered from above into the receiving space 20, the bottom 11a of the side body 11 is incorporated into the first opening 52, and the upper part of the receiving space 20 is incorporated into the second opening 53.

[0076] The material of the guide side body 51 is preferably the same as that of the receiving box 10. The height M1 of the guide side body 51 is preferably, for example, 60mm to 200mm. Furthermore, during the dispensing process, when the side body 11 is lifted and the polysilicon filler FI is dispensed from above into the receiving space 20, the height M2 of the bottom 11a of the side body 11, which is incorporated into the first opening 52, is preferably, for example, 10mm to 30mm. In addition, the height M3 of the second opening 53, which is incorporated into the upper part of the receiving space 20, is preferably 10mm to 30mm.

[0077] 〔Summarize〕

[0078] One aspect of the present invention relates to a clamp comprising: a side body forming an insertion space for inserting and accommodating a receiving bag containing polysilicon; a lifting portion disposed on the side body for lifting the side body; and a receiving tray detachably disposed at the bottom of the side body for supporting the receiving bag; wherein, when the side body is lifted, the receiving tray separates from the bottom of the side body, forming an opening at the bottom of the side body, and when the receiving bag is placed from above into the receiving space containing the receiving bag, the opening forms a placement path of the receiving bag from the insertion space to the receiving space.

[0079] According to the aforementioned configuration, a container bag containing polysilicon can be inserted into an insertion space formed by the side body of the clamp. Furthermore, a lifting portion for lifting the side body is provided on the side body. Therefore, the container bag and the side body can be lifted together while maintaining the container bag inserted into the insertion space of the clamp. Thus, the side body prevents the polysilicon from collapsing within the container bag when it is lifted, and prevents the container bag from locally bulging from its pre-lifting state.

[0080] Furthermore, the receiving tray located at the bottom of the side body supports the receiving bag, thus protecting the bottom of the receiving bag even when the clamp is moved while the receiving bag is inserted. Additionally, the receiving tray is detachably located at the bottom of the side body, creating an opening when detached. Therefore, when the receiving bag is inserted into the side body, lifting it and moving it above the receiving space, and then placing the receiving bag into the receiving space from above, a placement path for the receiving bag is formed through the opening from the insertion space to the receiving space. Thus, the side body can be used as a guide chute to place the receiving bag into the receiving space from above.

[0081] Furthermore, during the process of lifting the bagged polysilicon and placing it into the designated storage space, the side body can be used to prevent the storage bag from bulging locally, thus the clamp can be used to accurately place the storage bag into the storage space.

[0082] Furthermore, by adjusting the size of the clamps and the size of the storage space, the storage bag can be prevented from hitting partitions or other obstacles when it is placed into the storage space. Therefore, for example, when loading the storage bag into the box that forms the storage space, the storage bag can be prevented from breaking.

[0083] The opening can also be closed within a cross-section after the receiving space is cut with a plane that is approximately parallel to the horizontal plane.

[0084] According to the aforementioned configuration, the opening is contained within a cross-section formed by cutting the receiving space with a plane approximately parallel to the horizontal plane. Therefore, when the receiving bag is placed into the receiving space, the receiving bag will not come into contact with partitions or the like. Thus, for example, when inserting the receiving bag into the box that forms the receiving space, the receiving bag can be prevented from breaking.

[0085] To address the aforementioned problem, one aspect of the present invention relates to a method for manufacturing a polycrystalline silicon package, which uses the clamp to insert the receiving bag into a box forming the receiving space, thereby obtaining a polycrystalline silicon package. The manufacturing method includes: a lifting step, in which the receiving bag inserted into the clamp is lifted together with the clamp; and a placing step, in which the lifted clamp and the receiving bag are moved above a predetermined receiving space, and the receiving bag is placed from above the receiving space into the receiving space.

[0086] According to the aforementioned configuration, during the lifting process, the container bag containing polysilicon, inserted into the clamp, is lifted simultaneously with the clamp. Therefore, even when the container bag is lifted, the clamp can prevent the polysilicon from collapsing within the container bag and can prevent the container bag from partially bulging from its state before lifting.

[0087] Furthermore, during the dispensing process, the container bag is moved above the designated receiving space and remains inserted in the clamp until it is placed into the receiving space. As a result, localized bulging of the container bag is prevented before it is placed into the receiving space, allowing for accurate placement. Additionally, by adjusting the size of the clamp and the size of the receiving space, the container bag can be prevented from hitting the partitions of the receiving space. Therefore, for example, when loading the container bag into a box that forms the receiving space, breakage of the container bag can be avoided.

[0088] This invention is not limited to the above-described embodiments. Various modifications can be made within the scope of the claims. Embodiments obtained by appropriately combining disclosed technical means with different embodiments are all included within the technical scope of this invention.

Claims

1. A clamp, characterized in that, include: A side body having a cylindrical shape and forming an intercalation space for inserting a container bag for receiving polycrystalline silicon fragments from above. A lifting part, disposed on the side body, is used to lift the containing bag and the side body; as well as A receiving tray, detachably disposed at the bottom of the side body, is used to support the receiving bag; When the side body is lifted and the receiving tray detaches from the bottom of the side body, an opening is formed at the bottom of the side body. When the receiving bag is placed into the receiving space containing the receiving bag from above, the opening forms a placement path for the receiving bag from the insertion space to the receiving space. The opening closes within a cross-section that cuts the receiving space with a plane that is approximately parallel to the horizontal plane. The receiving plate has a protrusion and sidewalls; the protrusion is arranged along both ends of the receiving plate so as to project outwards; on the upper surface of the receiving plate, the sidewalls are arranged along the two ends in a manner perpendicular to the upper surface of the receiving plate.

2. A method for manufacturing a polycrystalline silicon package, characterized in that, The method for manufacturing a polycrystalline silicon package, which uses the clamp as described in claim 1 to insert the containing bag into a box having the containing space, includes: In the lifting process, the receiving bag inserted into the clamp is lifted together with the clamp; and In the delivery process, the lifted clamp and the container bag are moved above the predetermined receiving space, and the container bag is delivered into the receiving space from above.
