[0002] Pipe fitting manufacturers have a wide variety of pipe fittings. Various semi-finished pipe fittings in the pipe fitting processing process need to go through multiple processing steps, which means that the equipment used in a certain process needs to process semi-finished pipe fittings of different categories in succession. However, most of the commonly used pipe fitting production lines are continuous production lines for a type of pipe fitting, such as a pipe bending processing line disclosed in Chinese patent application number 201910882039.3, which is arranged in sequence including a first conveyor line for pipe fitting feeding, a pipe brushing workstation for brushing the surface of pipe fittings, a laser cutting device for pipe fitting cutting, and a hole expansion production line for pipe fitting expansion; the first conveyor line is connected to the pipe brushing workstation; a first manipulator for pipe fitting circulation is provided between the pipe brushing workstation and the laser cutting device; a third manipulator for pipe fitting circulation is provided between the laser cutting device and the hole expansion production line. This patent uses the first manipulator, the second manipulator and the third manipulator to transfer pipe fittings between continuously arranged process equipment, thereby improving processing efficiency. However, this continuous production line completes the entire processing flow of pipe fittings at one time, and the remaining categories of pipe fittings need to wait until this type of pipe fittings are completely processed. In general, the overall production plan for multiple categories of pipe fittings is difficult to reasonably adjust; the overall processing efficiency of the production line actually depends on the slowest process equipment. If this slowest process equipment does not have time to process, the remaining process equipment can only wait, and the utilization rate of the remaining process equipment is low; in addition, if a certain process equipment fails, the entire processing production line will stop, and the remaining normal process equipment will have to stop working, which greatly affects the overall processing efficiency.

DETAILED DESCRIPTION

[0028] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.

[0029] The present invention discloses a system for transferring and temporarily storing pipe fittings in processing areas of multiple categories, including a transfer road network, a transfer trolley, a temporary storage warehouse, and more than two discretely arranged specific processing areas, each of which corresponds to a processing procedure and the processing procedures of any two specific processing areas are different, the transfer road network can connect the temporary storage warehouse with each of the specific processing areas, and the transfer trolley walks along the transfer channel and is used to transfer pipe fittings between the temporary storage warehouse and the specific processing areas. For most categories of pipe fittings, it is necessary to go through each specific processing area in sequence to complete the processing. Of course, there are also some categories of pipe fittings that do not need to go through the procedures corresponding to several specific processing areas, but they also need to go through the remaining specific processing areas in sequence. The specific processing areas in this embodiment are discretely arranged and are not closely connected into a continuous and uninterrupted production line, so each specific processing area can complete the processing of a certain process of the pipe fittings alone, and then the transfer trolley can selectively transport these pipe fittings to the next specific processing area for processing in the next process, or transport them to the temporary storage warehouse for temporary storage. Therefore, the multi-category pipe fitting processing area transfer and temporary storage system of the present embodiment can meet the processing of multi-category pipe fittings, no matter which processes the pipe fittings need to go through, and no matter in what order the pipe fittings go through the required processes, the processing area transfer and temporary storage system of the present embodiment can meet and realize the processing of multi-category pipe fittings; from the perspective of a single specific processing area, as long as the transfer cart sends any category of pipe fittings to the specific processing area, the specific processing area can process the pipe fittings, so each specific processing area can process multiple categories of pipe fittings. Compared with the solution of a dedicated processing line for a specific category of pipe fittings, it is obviously greatly improved The utilization rate of processing equipment in the specific processing area is greatly improved, saving equipment costs.Moreover, when the transfer trolley of the present embodiment transports the processed pipe fittings in a certain specific processing area, it can choose to transport the pipe fittings to the specific processing area corresponding to the next process to directly carry out the next step of processing, or it can transport them to the temporary storage for temporary storage; in this way, when a certain specific processing area is very crowded and there is no time to process, the pipe fittings that need to be processed in the next step in the specific processing area can be transported to the temporary storage first, and when the specific processing area is no longer crowded, the transfer trolley can be used to transport such pipe fittings from the temporary storage to the specific processing area for processing; the advantage of this is that the crowded specific processing area will not cause the specific processing area corresponding to the previous process to be affected by its own congestion and be forced to Stopping processing will not cause a chain reaction in which all specific processing areas corresponding to the upstream process stop processing due to congestion. The specific processing areas corresponding to the upstream process can still continue processing, as long as the processed pipe fittings are first transported to the temporary storage warehouse for temporary storage, to ensure that the processing efficiency of the entire processing area transfer and temporary storage system will not be affected by the congestion of a certain specific processing area, and maintain high processing efficiency as a whole; and for the extreme case of a failure of the processing equipment in a certain specific processing area, the same is true. The specific processing area upstream of the specific processing area can still perform normal processing and temporarily store the processed pipe fittings in the temporary storage warehouse, which is an effect that the pipe fittings production line connected into a continuous processing line in the prior art does not have.

[0030] Since the multi-category pipe fitting processing area transfer and temporary storage system of this embodiment is suitable for processing multi-category pipe fittings, pipe fittings of the same category are usually processed as the same batch. For the convenience of classification, this embodiment preferably also includes a classification box for holding pipe fittings. Any pipe fittings of the same category in any of the classification boxes, that is, pipe fittings of the same category are placed in a classification box. Pipe fittings of the same category in the same batch usually require multiple classification boxes to hold. The transfer cart directly transfers the classification box, which is convenient and fast, and is convenient for the classification and shipment of pipe fittings in the later stage. In this embodiment, there are a large number of transfer carts, so a transfer control module is also included. The transfer control module can control the operation of the transfer cart. An identification code is set on the classification box, and a scanner is set in the specific processing area. When the classification box leaves the specific processing area, the identification code passes through the scanner, and the scanner updates the status of the classification box to the current process and uploads it to the transfer control module. The transfer control module can receive the output and output frequency of all the specific processing areas and judge whether the specific processing area is crowded. Then it can decide to transport the classification box output from any of the specific processing areas to The specific processing area corresponding to the next process may be transported to the temporary storage warehouse; specifically, a congestion threshold is set for each specific processing area in the transfer control module, and the received output volume and output frequency are converted into comparable values ​​and then compared with the congestion threshold to determine whether it is congested; if it is determined to be congested, the transfer cart is controlled to transport the classification boxes produced in the specific processing area corresponding to the previous process of the crowded specific processing area to the temporary storage warehouse; if it is determined to be not congested, the transfer cart is controlled to transport the classification boxes produced in the specific processing area corresponding to the previous process to the uncrowded specific processing area for processing.

[0031] The specific processing area described in this embodiment is divided into a primary forming area, a secondary forming area, a cleaning area, a welding area, an annealing area, an airtightness detection area, a polishing area, a sealing ring installation area, a marking area and a packaging area in order of the process. Each area has equipment that can perform corresponding processing procedures on pipe fittings. The temporary storage warehouse has a plurality of internal channels 3 arranged in the front-to-back direction and extending left and right. The internal channels 3 are connected to the transfer road network. The transfer vehicle travels between the specific processing area and the temporary storage warehouse through the transfer road network and travels inside the temporary storage warehouse through the internal channels 3. The above-mentioned specific processing areas are discretely arranged, and the temporary storage warehouse can intervene between any two specific processing areas to temporarily store the finished pipe fittings. Therefore, a reasonable layout and a reasonable setting of the transfer road network can reduce the travel distance of the transfer vehicle as much as possible, improve the transfer efficiency, and thus improve the overall processing efficiency of the processing area transfer temporary storage system. In this embodiment, the transfer road network preferably includes a first longitudinal channel 11 arranged on the left side of the temporary storage and extending in the front-to-back direction, and the first longitudinal channel 11 is connected to the internal channel 3; the initial forming area and the cleaning area are located on the left side of the first longitudinal channel 11, and the transfer road network also includes a first transverse channel 21 and a second transverse channel 22 connected to the left side of the first longitudinal channel 11 and extending in the left and right transverse directions, the first transverse channel 21 passes through the cleaning area, and the second transverse channel 22 passes through the initial forming area. One large category of pipe fittings can be cleaned after primary forming, while another large category of pipe fittings needs secondary forming after primary forming before they can be cleaned. Therefore, in this embodiment, the primary forming area and the cleaning area are both located on the left side of the first longitudinal channel 11. When the cleaning area is not crowded, the pipe fittings of the first large category can be directly transported to the cleaning area nearby, with a short distance and high efficiency. Specifically, the transfer vehicle passes through the second transverse channel 22 to the first longitudinal channel 11, and then passes through the second longitudinal channel 12 to the first transverse channel 21, and finally places the classification frame in the cleaning area, and the cleaning area cleans the pipe fittings in the classification frame; when the cleaning area is crowded, the transfer vehicle carries the classification frame from the second transverse channel 22 to the first longitudinal channel 11, and then to the internal channel 3, and places the classification frame in the temporary storage. The secondary forming process includes spinning cutting, tee hole opening and pulling, etc.

[0032] In this embodiment, the welding area and the secondary molding area are preferably located on the right side of the temporary storage area and arranged in a front-to-back interval, the annealing area is located on the right side of the welding area, and the transfer network also includes a second longitudinal channel 12 located on the right side of the temporary storage and connected to the internal channel 3, and a third transverse channel 23 and a fourth transverse channel 24 connected to the right side of the second longitudinal channel 12 and extending in the left and right transverse directions, the third transverse channel 23 passes through the welding area and the annealing area, and the fourth transverse channel 24 passes through the secondary molding area. For the second category of pipe fittings that need secondary molding, one is to be transported from the primary molding area to the temporary storage for temporary storage, and the other is to pass through the temporary storage, from the internal channel 3 to the second longitudinal channel 12, and then through the fourth transverse channel 24 to the secondary molding area, the path is short, and the efficiency is high. There are three sources of pipe fittings entering the welding area, the first is from the secondary molding area, the second is from the temporary storage, and the third is from the cleaning area, and the welding area is adjacent to the second longitudinal channel 12, so the paths of pipe fittings from these three sources to the welding area are very short, and the transportation efficiency is high. After welding, the pipe fittings need to enter the annealing zone for annealing treatment. The annealing zone of this embodiment is located on the right side of the welding zone, adjacent to the conveying path section.

[0033] After annealing, the pipe fittings are already semi-finished pipe fittings that have been roughly formed. The subsequent processes that need to be carried out are air tightness testing, polishing, sealing ring installation, marking and packaging, which are simple and in the final stage. It is not easy to be crowded. Usually, pipe fittings can carry out these processes continuously. The degree of intervention of the temporary storage warehouse is not high. Therefore, in this embodiment, this type of specific processing area is arranged in an area far away from the temporary storage warehouse, and the position between this type of specific processing area and the temporary storage warehouse and the upstream specific processing area is used to set the finished product area. Specifically, this embodiment preferably also includes a first finished product warehouse and a second finished product warehouse, the first finished product warehouse is located behind the temporary storage warehouse and the secondary molding area, the second finished product warehouse is located on the right side of the secondary molding area, and the transfer road network also includes a third longitudinal channel 13 and a fifth transverse channel 25, the third longitudinal channel 13 passes through between the secondary molding area and the second finished product warehouse and connects the third transverse channel 23 and the fourth transverse channel 24. The third longitudinal channel 13, the fifth transverse channel 25 is located at the rear of the first finished product warehouse and connected between the first longitudinal channel 11 and the third longitudinal channel 13. The first finished product warehouse is surrounded by the first longitudinal channel 11, the third longitudinal channel 13, the fourth transverse channel 24 and the fifth transverse channel 25, and the first finished product warehouse is located between the several specific processing areas in the above-mentioned finishing stage and the upstream specific processing area, so the first finished product warehouse is in a relatively core location, and all the specific processing areas are arranged around the first finished product warehouse, which further improves the space utilization rate, reduces the distance between each other, reduces the path length of the transfer road network, improves the transfer efficiency, and improves the overall processing efficiency. The second finished product warehouse can also store finished products, which is close to the annealing area. The annealing area is far away from the temporary storage warehouse and the air tightness detection area. Therefore, if some pipe fittings do not need to be quickly processed and shipped, after the annealing is completed, the above-mentioned finishing stage process will not be carried out temporarily. They can be stored in the second finished product warehouse nearby, so that the pipe fittings that are eager to be processed and shipped can first carry out the specific processing procedures in the finishing stage. The second finished product warehouse also serves as a temporary storage.

[0034] The air tightness detection area and the polishing area are located at the rear side of the fifth transverse channel 25, and the air tightness detection area and the polishing area are arranged at intervals on the left and right. The sealing ring installation area and the marking area are located next to the polishing area. The packaging area is located on the right side of the first finished product area and the rear side of the second finished product area. The third longitudinal channel 13 passes between the first finished product area and the packaging area. These specific processing areas belong to the process of the finishing stage. Under normal circumstances, the pipe fittings can complete the above process continuously. The distance between these specific processing areas is short and the transfer efficiency is high. The packaging area is only separated from the first finished product area by the third longitudinal channel 13, and the packaging area is only separated from the second finished product area by the fourth transverse channel 24. Therefore, the path for transferring the pipe fittings from the packaging area to the first finished product warehouse or the second finished product warehouse is also short, and the transfer efficiency is high. Regardless of whether the channel in the transfer road network passes through a specific processing area or is adjacent to a specific processing area, the specific processing area has a bearing platform that can dock with the classification frame of the transfer trolley, and each of the specific processing areas has a bearing platform adjacent to the transfer road network, and the bearing platform is used to dock with the classification frame of the transfer trolley. The transfer vehicle adopts an AGV vehicle, and path navigation codes are affixed to the transfer road network and the internal channel 3. The transfer vehicle moves along the channel according to the path navigation code.
