Description

Technical Field

[0001] The present invention relates to the technical field of sponge processing, in particular to a gantry movable storage method for sponge production. Background Art

[0002] At present, when some sponge blocks are being processed and loaded, there is no specific place to put the excess sponge blocks, so they need to wait. If necessary, a sponge storage workshop needs to be designed outside the processing workshop to store the sponge blocks through storage racks, and manual work is required to pick up and load the materials.

[0003] The Chinese invention patent with publication number CN213946687U provides a sponge production and processing workshop that combines storage and cutting processing. The workshop places sponge blocks upright in the storage area, which has high space utilization. Combined with the positioning function of the trolley, it can achieve a flexible warehouse layout, which has higher space utilization than the traditional storage rack method.

[0004] However, the above workshop still has some defects. It is necessary to manually determine the storage location corresponding to the sponge, and then issue instructions to the walking cart to move to the designated storage location for transportation, placement or retrieval. In addition, the sponge information in the storage location needs to be recorded manually, and the degree of intelligence is low.

[0005] Therefore, the present invention proposes a gantry mobile storage method for sponge production to solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a gantry mobile storage method for sponge production, implement system accounting, and realize intelligent sponge storage.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: a gantry movable storage method for sponge production, the innovation of which is that the storage method comprises the following steps:

[0008] Step 1: Storage location planning: plan and form several storage locations in the warehouse, establish a logical coordinate system in the program system, and plan the logical storage location;

[0009] Step 2: Sponge labeling: attach an RFID carrier to the sponge. The RFID carrier contains sponge information, including sponge type, length, weight, batch, and foaming date.

[0010] Step 3: Establish a basic information database of sponges. The basic information database of sponges is established in the program system according to the types of sponges, including the types, names, widths and heights of sponges.

[0011] Step 4: Establish a real-time inventory information database, read the RFID carrier of the sponge, and establish a real-time warehouse inventory information database based on the RFID carrier, including the sponge type, length, weight, batch, foaming date, storage date and storage location, to manage the sponge information in the warehouse online;

[0012] Step 5: Warehousing: The gantry crane automatically locates to the warehouse entrance to grab the sponge, reads the RFID carrier, obtains the sponge information, and manually specifies or the program system automatically searches for a suitable storage location according to corresponding rules. The gantry crane automatically locates to the designated storage location, the sponge is put into storage, and the sponge storage information, including the storage date and storage location, is recorded, and the sponge information in the storage location is updated;

[0013] Step 6: Delivery. Input the sponge information required for delivery into the program system. The location of the appropriate sponge is manually specified or automatically searched by the program system. The gantry crane automatically locates to the specified location, takes the sponge out of the warehouse, updates the sponge information in the location, and records the sponge delivery information, including sponge type, location, delivery time and order number.

[0014] Step 7: Sorting the warehouse. During the sorting process, every time the sponge changes its position, the sponge position change information is recorded, including the sponge type, storage location and storage time, to facilitate the tracing of the sponge's movement trajectory, error correction and system maintenance.

[0015] Furthermore, in step 1, the method for logical storage location planning is:

[0016] Step 1-1: Design the mechanical structure of the inlet and outlet conveyor lines and mobile gantry crane based on the length and width dimensions of the warehouse;

[0017] Step 1-2: According to the length and width of the warehouse, subtract the footprint of the mechanical structure to obtain the length L and width W of the sponge;

[0018] Step 1-3: Calculate the number of sponges that can be placed in the width direction according to the formula COLUMN=W / (WIDTH+W1), where WIDTH is the maximum width of the sponge and W1 is the safety distance calculated based on the opening range of the gantry crane clamp.

[0019] Step 1-4: Calculate the number of sponges ROW that can be placed in the length direction according to the formula: RROW=L / (LENGTH+L1), where LENGTH is the maximum length of the sponge and L1 is the safety distance in the length direction.

[0020] Furthermore, in step 5, the corresponding rules include:

[0021] Time priority rule: the sponges that enter the warehouse first are stored first;

[0022] Empty storage location priority rule: if there is an empty storage location, the sponge will be stored in the empty storage location first;

[0023] Same batch rule: sponges from the same batch are stored in the same storage location;

[0024] Width size priority rule: sponges of the same width size are stored in the same storage location;

[0025] The program system searches for the storage location of the appropriate sponge in the order of time priority rule, empty warehouse location priority principle, same batch rule, and width size priority rule.

[0026] Furthermore, in step 5, after the gantry crane automatically locates the designated storage location, it reads the current storage location content in the program system and determines whether it is suitable according to the corresponding rules. If it is suitable, the cotton is sent into the warehouse. If it is not suitable, the next option obtained by searching according to the corresponding rules is selected.

[0027] Furthermore, in step 6, after the gantry crane automatically locates the designated storage location, it reads the RFID carrier of the corresponding sponge to determine whether the sponge meets the requirements. If the sponge meets the requirements, the sponge is taken out of the warehouse; if the sponge does not meet the requirements, the sponge is placed in the original storage location, the storage location data is updated according to the read sponge information, and the next option obtained from the search is selected.

[0028] Furthermore, in step 5 and step 6, the updated sponge information in the storage location includes the sponge type, length, weight, batch, foaming date, storage date and storage location.

[0029] Furthermore, the program system has query methods including the type, name, storage location, and movement trajectory of the sponge.

[0030] Furthermore, the program system has a QR code scanning and adding function and a data report importing function for adding new sponge varieties.

[0031] Furthermore, the program system has a data report output function for providing a report on in-stock data and a report on in-stock sponge data within a time period.

[0032] The advantages of the present invention are:

[0033] In the warehousing method of the present invention, system accounting is used to replace manual accounting, and an RFID carrier is attached to the sponge to facilitate the system to read and record sponge information, reduce repetitive work caused by errors due to human factors, greatly reduce the workload of inventory and manual labor intensity, use gantry crane for automatic positioning, improve work efficiency, reduce labor costs, and realize intelligent sponge warehousing.
