Description

Technical Field

[0001] The present invention relates to the technical field of hanging systems, and in particular, to a hanging transportation method. Background Art

[0002] The garment processing industry is a labor-intensive industry. The traditional garment processing industry is characterized by strong dependence on manual labor, which seriously affects processing efficiency. At present, the material transportation process in garment processing is as follows: After the cutting process completes the material cutting, the cut materials are manually hung on the hanger, and the hanger is manually pushed to the sewing process. Since different sewing processes are assigned to multiple workshops, each workshop has a corresponding loading entrance. It is necessary to manually determine which workshop the hanging is to be sent to, and push the hanging to the loading entrance of the corresponding workshop. The traditional garment processing industry cannot perform intelligent evaluation of working conditions. The staff of the sewing process manually judge the material accumulation situation according to the processing conditions of the workshop, and feedback to the hanging pusher. The delivery quantity and speed of the hanging require manual intervention. This material distribution and processing mode seriously affects the processing efficiency of the garment industry.

[0003] Therefore, the requirements for the intelligence of the hanging system are getting higher and higher. For example, Chinese invention patent CN105600294A discloses an intelligent hanging system, including a main transport circulation channel and a plurality of branch channels forked from the main transport circulation channel, and a track change mechanism is set at the fork of the main transport circulation channel and the branch channel. Each hanging is assigned a different radio frequency identification card, which is loaded by the loading end of the main transport circulation channel and is assigned to different branch channels before loading. When the hanging runs to the fork of the branch channel, the card reader reads the radio frequency identification card information to determine whether it should enter the branch channel. If it should enter the branch channel, the track change mechanism is connected to the branch channel, and the hanging enters the branch channel; if it should not enter the branch channel, the track change mechanism is connected to the main transport circulation channel, and the hanging continues to circulate on the main transport circulation channel. If a branch alarms, the direction of the hanging can be adjusted through the control terminal. If all branches are alarmed, the main transport circulation channel stops running.

[0004] However, the above hanging system still has the following shortcomings: when there are too many hangings released onto the main transport circulation channel, all hangings cannot be run to the branch channel, resulting in more and more hangings on the main transport circulation channel, which not only affects the recognition efficiency but also causes the hangings to derail; if the redundant hangings on the main transport circulation channel are removed, it is also easy to cause some clothing to be unable to reach the corresponding process. The probability of abnormality in the entire hanging transportation is relatively high, and frequent intervention by staff is still required.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable hanging transportation method. Summary of the invention

[0006] The purpose of the present invention is to provide a hanging transportation method, which is simple and convenient, and effectively utilizes the upper rail and the storage rail to store the carrier. When the process track needs goods, the carrier passes through the circular rail to reach the process track, reducing the load of the circular rail, and is expanded by the full load capacity of the process track, effectively reducing the redundancy of the carrier on the circular rail, having high intelligence and reducing the dependence on the intervention of staff.

[0035] Embodiment 1: Figure 1 , 2 As shown, Figure 1 It is a schematic diagram of a flow chart of a hanging transportation method of the present invention. Figure 2 It is a structural schematic diagram of a hanging transportation system in a hanging transportation method of the present invention; it is only one of the embodiments of the present invention, a hanging transportation method, applicable to a hanging transportation system, including a carrier 6 and a transportation track, the transportation track includes an upper rail 1, a storage rail 2 connected to the upper rail 1, a ring rail 3 connected to the storage rail 2, and a process track 4 connected to the ring rail 3, the ring rail 3 is connected to an abnormal rail 5, and the number of the carrier 6 is at least one;

[0036] In the present invention, the shelving track is the track for shelving clothing, the storage track is the track for temporary storage, and the end of the process track away from the circular track is connected to the clothing processing workshop; the carrier is initially placed on the shelving track, and when clothing is hung on the carrier, it will pass through the storage track, the circular track and the process track to reach the processing workshop.

[0037] Here, the shelf track is preferably also set up in a circular shape. The storage track is used to connect the shelf track and the circular track, and there can be multiple storage tracks. The process track is used to connect the circular track and the processing workshop. There can be multiple processing workshops, and there can also be multiple process tracks between a single processing workshop and the circular track.

[0038] The vehicle can have the ability to self-drive and run on the transport track, and can also be transported on the track by external force to hang the clothing on the vehicle for transportation.

[0039] The following steps are involved:

[0040] S1: When there is cargo on the carrier on the rack track, drive the carrier to move to the storage track;

[0041] As an optional embodiment of the present application, there are many carriers on the upper rail, and they all move in a circular motion on the upper rail, but the movement speed is slow. When clothing or processed parts (hereinafter collectively referred to as goods) are hung on the carrier, the carrier carrying the goods is moved to the storage track.

[0042] The storage track is used for temporary storage of goods so that the carriers carrying the goods on the shelves do not directly reach the circular track, thereby reducing the load on the circular track.

[0043] S2: Determine whether a signal for goods to be requested from the process track is received; if so, release the carrier on the storage track to move cyclically on the circular track, and execute step S3; otherwise, do not execute the operation;

[0044] As an optional embodiment of the present application, when the processing workshop needs goods for processing, it will notify the process track of the goods request signal. At this time, a certain amount of carriers carrying goods need to be released from the storage track to the circular track, and then they need to pass through the process track from the circular track to the processing workshop for processing.

[0045] S3: The carrier moves from the circular track to the process track;

[0046] As an optional embodiment of the present application, the carrier that has reached the circular track needs to be moved to the process track to facilitate reaching the processing workshop from the process track for garment processing.

[0047] S4: Determine whether the number of carriers arriving at the process track reaches a first predetermined value, if yes, continue to execute step S5; otherwise, return to step S3;

[0048] As an optional embodiment of the present application, the carrier load on the process track is set. When the number of carriers reaches the predetermined full load, that is, the first predetermined value, generally speaking, the process track does not allow other carriers to reach the process track. Therefore, here, it is necessary to judge in real time whether the process track is predetermined to be full. Once it is full, the next control operation can be continued; on the contrary, if the process track is not predetermined to be full, then continue to run the carrier onto the process track, that is, execute step S3.

[0049] S5: Determine whether there is a carrier on the circular track within the predetermined time. If yes, move the carrier on the circular track to the process track and execute step S6; otherwise, move the carrier on the process track to the next process;

[0050] As an optional embodiment of the present application, considering that the number of carriers on the storage track is very large, it is easy to cause too many carriers to be derailed. For example, there is a derailed carrier piled up between two adjacent mounting stops. When step S2 is executed, the number of carriers released from the storage track and arriving on the circular track will be greater than the original number. Then, when the number of carriers on the process track reaches the predetermined full load, there are still redundant carriers on the circular track.

[0051] Until the next time the process track needs goods, if the storage track releases excessive vehicles again, the number of redundant vehicles on the circular track will increase, affecting safety and requiring manual intervention.

[0052] Unlike the conventional process track which no longer accepts carriers after being fully loaded, in the present invention, the redundant carriers on the circular track are directly moved further to the process track.

[0053] Of course, if there are no redundant carriers on the circular track, there is no need for redundant processing, and all carriers on the process track can be directly run to the processing workshop for processing.

[0054] S6: Determine whether the number of carriers on the process track is not less than a second predetermined value and there are still carriers on the circular track. If so, move the carriers on the circular track to the abnormal track; otherwise, move the carriers on the process track to the next process.

[0055] Of course, when the number of carriers on the process track is not less than the second predetermined value and there are still carriers on the circular track, the remaining carriers on the circular track will be run to the abnormal track, and the carriers that have reached the second predetermined value on the process track will still be run to the next process.

[0056] As an optional embodiment of the present application, the second predetermined value is greater than the first predetermined value, and the second predetermined value is the expanded load capacity of the process track. The redundant carriers on the circular track are moved to the process track. As long as the number of carriers on the process track does not reach the expanded load, the process track can receive redundant carriers.

[0057] Here, the expanded load cannot exceed the maximum bearing capacity of the process track to prevent damage to the process track; when the process track is small, the vehicle carrying the expanded load should not affect the normal operation of the process track.

[0058] Of course, if there are too many redundant vehicles on the circular track, even if the number of vehicles on the process track has reached full load, there are still extra vehicles on the circular track. In this case, while the vehicles on the process track are run to the next process, the remaining vehicles on the circular track can only be run to the abnormal track, and manual intervention can only be performed at this time.

[0059] On the contrary, if there are no carriers on the circular track, then the process track does not need to receive new carriers, and all carriers on the process track can be directly run to the processing workshop for processing.

[0060] It should be noted that, generally speaking, the expanded load of the process track can fully receive the extra vehicles released to the circular track, which can greatly reduce the probability of redundancy on the circular track; each time the process track needs goods, it will make decisions on reserved full load and expanded load in turn to ensure that there are no extra vehicles on the circular track and reduce the frequency of manual intervention.

[0061] For example, the process track requires 5 vehicles, the scheduled full load will also be 5 vehicles, and the expanded full load is set to 7 vehicles. If the process track requires 6 vehicles, the number of vehicles released from the storage track to the circular track at one time is 6, then these 6 vehicles can be transported to the process track for transportation to the processing workshop; if the process track requires 8 vehicles, then only 7 vehicles can be transported to the process track for transportation to the processing workshop, and the remaining one can only reach the abnormal track, which requires manual intervention.

[0062] The invention provides a hanging transportation method, which is simple and convenient, and effectively utilizes the upper rail and the storage rail to store the carrier. When the process track needs goods, the carrier passes through the circular rail to reach the process track, thereby reducing the load of the circular rail, and is expanded by the full load capacity of the process track, thereby effectively reducing the redundancy of the carriers on the circular rail, being highly intelligent, and reducing the dependence on the intervention of the staff.

[0063] Embodiment 2: Still as Figure 1 , 2The figure shown is only one of the embodiments of the present invention. On the basis of the first embodiment, in a hanging transportation method of the present invention, it is preferable that an input terminal for obtaining data of the mounted cargo and a display terminal for displaying the input data are provided on the carrier; when the cargo is loaded onto the carrier, the parameters of the cargo are input into the carrier, and the carrier also displays the information to facilitate the query of cargo parameters; the information display method in the carrier can be a display screen display, information code generation, and video transmission signal, etc.

[0064] When executing step S1, when there is cargo mounted on the carrier on the rack track, the carrier enters the data of the cargo and displays it; it is determined whether the carrier has data entered, and if so, the carrier is driven to run to the storage track; otherwise, no operation is performed.

[0065] This is equivalent to setting up a verification between the loading track and the storage track to prevent too many vehicles, causing vehicles without cargo, vehicles with cargo but no cargo signals recorded, and vehicles with damaged structures to reach the storage track.

[0066] Similarly, when executing step S3 and step S5, when the carrier moves from the circular track to the process track, it is determined whether the carrier has data entered. If so, the carrier moves to the process track; otherwise, no operation is performed.

[0067] This is equivalent to setting up another verification between the circular track and the process track to prevent the vehicle from reaching the storage track, which is normal. However, if damage occurs during storage and operation, these vehicles will be blocked to prevent them from reaching the process track.

[0068] Combined with the expansion and loading of the process track, the vehicles that have reached the circular track and have normal data recognition will be received onto the process track. Ultimately, only the vehicles that have no entered data (or cannot recognize the entered data) will not be able to reach the process track and can only run on the circular track to the abnormal track.

[0069] As an option of the embodiment of the present application, the number of the storage tracks is at least two;

[0070] When executing step S1, the vehicle is moved to the corresponding storage track according to the vehicle display data.

[0071] As an option in the embodiment of the present application, the number of the process track is at least one;

[0072] When executing step S2, when a signal of demand for goods is received from the process track, a corresponding number of carriers on the storage track are released to arrive at the circular track for circular displacement according to the sum of the demand quantities of all process tracks; for example, if there are two process tracks demanding goods, one process track demands 5 carriers, and the other process track demands 9 carriers, then 14 carriers on the storage track are released to arrive at the circular track; and since the circular track is a closed circular structure, the carriers arriving at the circular track will perform periodic circular displacement on the circular track.

[0073] It should be noted that, when executing step S4, the first predetermined value of the process track is the required quantity of the process track.

[0074] Here, when the end points of multiple process tracks are the same processing workshop, the scheduled full load and expanded full load of these process tracks are also the same. If there are still vehicles on the circular track after the scheduled full load is reached, the multiple vehicles on the circular track should be evenly distributed to these process tracks to avoid large differences in the number of vehicles on different process tracks, which can also increase the service life of the track.

[0075] As an option in the embodiment of the present application, the annular track is connected to the process track via a lifting structure;

[0076] When executing step S3, the carrier is moved from the circular track to the process track by the lifting structure.

[0077] As an option in an embodiment of the present application, when executing step S5, the time it takes for the vehicle to run around the circular track for one cycle is used as the predetermined time.

[0078] That is, when the vehicle runs around the circular track for one week, theoretically the vehicle has passed through all process tracks but has not been received by the process track, that is, the process track has been fully loaded and cannot receive the vehicle temporarily. At this time, redundant vehicle reception is required.

[0079] As an optional embodiment of the present application, when executing step S5, if there is a carrier on the circular track within the predetermined time, a carrier on the circular track will be run to the process track. That is, after reaching the predetermined full load, the process track can only receive one carrier at a time to avoid exceeding the expansion load.

[0080] Finally, when executing steps S5 and S6, after the carrier on the process track is moved to the next process, the carrier is moved back to the loading track, and the input data in the carrier is cleared.

[0081] The invention provides a hanging transportation method, which is simple and convenient, and effectively utilizes the upper rail and the storage rail to store the carrier. When the process track needs goods, the carrier passes through the circular rail to reach the process track, thereby reducing the load of the circular rail, and is expanded by the full load capacity of the process track, thereby effectively reducing the redundancy of the carriers on the circular rail, being highly intelligent, and reducing the dependence on the intervention of the staff.

[0082] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
