Description

Technical Field

[0001] The present application relates to the technical field of isostatically pressed graphite, and in particular to a method for packaging large-scale isostatically pressed graphite. Background Art

[0002] During the production process of isostatic graphite, some isostatic graphite is cylindrical and has large specifications according to needs. The existing large-size isostatic graphite is mostly placed directly in the warehouse, which makes it inconvenient to transport during turnover within the factory. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a large-scale isostatic graphite packaging method, which has the advantage of being easy to circulate and transport within the factory.

[0004] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0005] A method for packaging large-scale isostatic graphite includes the following steps: a cleaning step of cleaning a tray and a cover plate; a transferring step of transferring the isostatic graphite to the tray and placing the cover plate on top of the isostatic graphite; a packaging step of packaging the tray and the cover plate with a packaging tape; and a storage step of transferring the packaged isostatic graphite to a storage area.

[0006] By adopting the above technical solution, in production, by placing the isostatic graphite on a pallet and packaging it with a cover plate and a packing tape, it is possible to transfer the isostatic graphite by lifting the pallet with a forklift, thereby achieving transfer of the isostatic graphite, which is more convenient.

[0007] In a preferred example, the present application can be further configured as follows: before the cleaning step, a pressurizing step is also included, in which a preset pressure is applied to the tray for a preset time. If the tray is not damaged, the cleaning step is entered.

[0008] By adopting the above technical solution and performing a pressure test on the pallet, the probability of damage to the pallet during placement or transportation is reduced.

[0009] In a preferred example, the present application can be further configured as follows: in the cleaning step, impurities are cleaned from the surfaces of the tray and cover plate that are in contact with the isostatic graphite. During the cleaning process, if any abnormality is found, the number of abnormalities recorded for the tray and / or cover plate is retrieved. If the number is greater than a preset value, the tray and / or cover plate is discarded.

[0010] By adopting the above technical solution, when an abnormality is found during the cleaning process, the number of times the pallet has been abnormal is judged, that is, the number of times it has been used since the initial abnormality. When the number of times is greater than a certain number, the pallet and / or cover is discarded, thereby reducing the probability of damage during use.

[0011] In a preferred example, the present application can be further configured as follows: if the number of times is not greater than a preset value, the weight of the isostatic graphite of the previous batch is retrieved and compared with the weight of the isostatic graphite of the current batch; if the weight of the isostatic graphite required to be carried by the tray of the current batch is greater than the weight of the isostatic graphite required to be carried by the previous batch, the tray and / or cover plate is discarded.

[0012] By adopting the above technical solution, by comparing the weight of the isostatic graphite carried last time with that carried last time, when the weight is greater than the weight required to be carried last time, the tray and / or cover plate is discarded, thereby reducing the probability of damage during use.

[0013] In a preferred example, the present application can be further configured as follows: in the transfer step, pad one is placed on the tray, isostatic graphite is placed on pad one, pad two is placed on top of the isostatic graphite, and then the cover plate is placed on pad two.

[0014] By adopting the above technical solution and providing the first and second cushion layers, the probability of isostatic graphite wear can be reduced.

[0015] In a preferred example, the present application can be further configured as follows: in the transfer step, the diameter of the current isostatic graphite is obtained, and the bearing area of the tray is divided into bearing areas, with one bearing area corresponding to one isostatic graphite.

[0016] By adopting the above technical solution, when the specifications of the isostatic graphite are small, a single tray can invert more isostatic graphite.

[0017] In a preferred example, the present application can be further configured as follows: during the division process, the bearing area is divided into a main support area and an auxiliary support area, the anomaly is located in the auxiliary support area, and when the bearing area covers part of the main support area and part of the auxiliary support area, the overlapping area of a single bearing area and the auxiliary support area is less than 15% of the area of a single bearing area.

[0018] By adopting the above technical solution, when multiple isostatic graphites need to be supported, the overlap between the isostatic graphites and the abnormal parts is reduced, thereby reducing the pressure on the abnormal parts, thereby reducing the probability of damage to the abnormal parts during use. DETAILED DESCRIPTION

[0019] The present application discloses a method for packaging large-scale isostatic graphite, comprising the following steps: a pressurizing step, applying a preset pressure to a pallet for a preset time; if the pallet is not damaged, entering a cleaning step; a cleaning step, cleaning the pallet and the cover; a transferring step, placing a first cushion layer on the pallet, placing the isostatic graphite on the first cushion layer, placing a second cushion layer on top of the isostatic graphite, and then placing the cover on the second cushion layer; a packaging step, packaging the pallet and the cover with packaging tape; and a storage step, transferring the packaged isostatic graphite to a storage area. In this embodiment, the pallet can be a wooden pallet or a plastic pallet that can be used by a forklift.

[0020] During the cleaning step, the surfaces of the pallet and cover that come into contact with the isostatic graphite are cleaned of impurities. If any abnormality is detected during the cleaning process, the number of abnormalities recorded for the pallet and / or cover is retrieved. If the number exceeds a preset value, the pallet and / or cover is discarded. In this application, abnormalities include, for example, missing or broken planks on a wooden pallet or missing or broken planks on a plastic pallet.

[0021] If the number is not greater than the preset value, the weight of the isostatic graphite of the previous batch is retrieved and compared with the weight of the isostatic graphite of the current batch. If the weight of the isostatic graphite required to be carried by the tray of the current batch is greater than the weight of the isostatic graphite required to be carried by the previous batch, the tray and / or cover plate is discarded.

[0022] In the transfer step, the diameter of the current isostatic graphite is obtained, and the bearing area of the tray is divided into bearing areas, where one bearing area corresponds to one isostatic graphite.

[0023] During the division process, when the bearing area can bear multiple isostatically pressed graphites, the bearing area is divided into a main supporting area and an auxiliary supporting area, and the abnormality is located in the auxiliary supporting area. When the bearing area covers part of the main supporting area and part of the auxiliary supporting area, the overlapping area of a single bearing area and the auxiliary supporting area is less than 15% of the area of a single bearing area.

[0024] If the load area can only support one piece of isostatic graphite, place the piece on the pallet away from the abnormal point to minimize the overlap between the piece and the abnormal point. After the piece is placed, place markers symmetrically on the pallet, centered around the piece, to guide the forklift.

[0025] The pallet is also numbered. When an abnormality occurs, the number is entered into the control system. The control system includes an identification module installed on the forklift for identifying the pallet number. When an abnormal pallet number is identified, the operator is reminded to confirm the position of the marker. When there is no marker, the operator reports no marker and gives up transferring the current pallet.

[0026] The implementation principle of this embodiment is as follows: by providing pallets, it is convenient to transport isostatic graphite. At the same time, during the packaging of isostatic graphite, the pallets are inspected, and abnormal pallets are discarded or used in a restricted manner, thereby reducing the probability of pallet damage during transportation.

[0027] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
