Description

Technical Field

[0001] The present invention relates to the technical field of seal dispensing machines, and in particular to a seal dispensing machine with a pre-dispensing function and a seal dispensing method. Background Art

[0002] During the transportation and use of containers, in order to ensure the safety of the containers, the traditional method is to use container-specific mechanical seals. Before the container is shipped, the container is sealed with a mechanical seal. When it arrives at the destination, the seal is checked to see if it is intact to determine whether the items in the container have been tampered with during transportation.

[0003] Currently, domestic container terminals primarily use a manual process for container seal storage, inventory, dispatch, allocation, and tracking, primarily through a four-tiered dispatch process involving liner companies, liner company agents, fleets, and drivers. This manual process presents numerous drawbacks, including complex operations, high communication costs, delayed information transmission, traffic congestion, low efficiency, high binding error rates, and ineffective safety assurance. Furthermore, due to the authorization requirements of various major shipping companies, many terminals currently use container seals of varying shapes and sizes, resulting in inefficient seal distribution. This significantly hinders the management of seal storage, distribution, and seal data collection.

[0004] In order to solve the problem of low efficiency caused by manual distribution, some distribution machines that can realize automatic distribution have come into being. In the existing distribution machines, the traditional distribution process is that when the sealing machine receives the distribution task, it drives the machine to move to the designated cargo aisle position, turns on the seal recognition function, and ships the goods if the recognition is successful, and recycles them if the recognition fails. Although it can improve the distribution efficiency to a certain extent, it will inevitably take a lot of time to identify and distribute after receiving the distribution task. Therefore, there is still a lot of room for improvement in the distribution efficiency. Summary of the Invention

[0005] One of the objectives of the present invention is to provide a seal dispensing machine with a pre-dispensing function, aiming to solve the problem of low seal dispensing efficiency existing in existing seal dispensing machines.

[0006] A second object of the present invention is to provide a seal distribution method, aiming to solve the problems of low seal distribution efficiency and inconvenient management in the existing seal distribution process.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] In a first aspect, a seal dispensing machine with a pre-dispensing function is provided, comprising:

[0009] Multiple cargo lanes, where the same cargo lane is used to store the same type of seals;

[0010] A plurality of pre-distribution storage devices, each of which includes a storage box for temporarily storing seals, wherein each storage box stores only one seal;

[0011] A pickup device, used to take out the seals on the cargo lane or transport them to the pre-distribution storage device, the pickup device also including an identification mechanism for identifying the seals on the cargo lane;

[0012] A recording device for recording the seal model on all cargo aisles and the seal code of the first seal on all cargo aisles;

[0013] A delivery device, used for taking out the seal temporarily stored in the storage box;

[0014] a control device electrically connected to the pre-distribution storage device, the pickup device, the recording device, and the delivery device;

[0015] When no seal retrieval request is received, the control device controls the retrieval device to traverse all aisles to be identified, and the control device controls the identification mechanism to identify the seal codes of the first seals arranged on the aisles to be identified and transmit them to the recording device. The retrieval device transports some of the seals to the storage box and transmits the seal codes of the transported seals to the recording device. The aisles to be identified are the aisles for which the seal codes of the first seals are not recorded in the recording device.

[0016] When receiving a seal extraction request, if the seal corresponding to the seal model to be extracted has been placed in the storage box, the control device controls the delivery device to remove the seal; if the seal model to be extracted has not been placed in the storage box, the control device controls the retrieval device to directly remove the seal.

[0017] Optionally, the seal dispensing machine further comprises a delivery device, which comprises a delivery box and a delivery conveyor belt. The delivery box is arranged on one side of the storage box, the delivery box is provided with a delivery channel, and the delivery conveyor belt is located below the storage box and the delivery box.

[0018] In a second aspect, a seal dispensing method is provided, which uses the seal dispensing machine with a pre-dispensing function to distribute seals, comprising the following steps:

[0019] S1. Pre-distribution: The control device controls the pickup device to traverse all aisles to be identified, controls the identification mechanism to identify the seal code of the first seal arranged in the aisle to be identified and transmits it to the recording device. The pickup device pushes some seals into the storage box and transmits the seal code of the pushed seal to the recording device.

[0020] S2. Pick up the seal. If the seal corresponding to the seal model to be picked up has been placed in the storage box, the control device controls the delivery device to take out the seal. If the seal code of the first seal corresponding to the seal model to be picked up has been recorded by the recording device and has not been placed in the storage box, the control device controls the picking device to take out the seal. If the seal code of the first seal corresponding to the seal model to be picked up has not been recorded by the recording device and has not been placed in the storage box, the control device controls the picking device to move to the cargo aisle where the corresponding seal model is located, controls the identification mechanism to identify the seal code of the first seal in the cargo aisle, and then controls the picking device to take out the seal.

[0021] When no seal extraction request is received, step S1 is executed; when a seal extraction request is received, step S2 is executed.

[0022] Optionally, in step S1, when the operating environment of the seal dispensing machine reaches the pre-distribution conditions, each time a seal is identified, it is checked whether there is a seal missing in the storage box. If there is a seal missing in the storage box, the successfully identified seal will be placed in the storage box.

[0023] Optionally, in step S1, one of the cargo lanes in the seal dispensing machine for which no identification result has been obtained is selected for identification.

[0024] Optionally, in step S1, after completing one identification, check whether there is a storage box of this seal type and no seal in the storage box in the results of successful identification in the seal dispensing machine. If there is a storage box without this seal type, pour the seal into the storage box; otherwise, execute the next identification process.

[0025] Optionally, in step S1 , if all storage boxes are equipped with seals and the aisles in the seal dispensing machine have completed identification, the identification is stopped and the pre-distribution process ends.

[0026] Optionally, in step S1, if the seal recognition fails continuously and the cargo lane has reached the recycling number, the recognition is stopped and the pre-distribution process ends.

[0027] Optionally, when the driver picks up the seals, if the required seals exist in the storage box, after the seals in the storage box are dispatched, the pushing device and the picking device will refill the storage box with seals of the same type.

[0028] Optionally, when step S1 is being executed, if the seal distribution system receives a retrieval request, step S1 is immediately terminated and step S2 is executed.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The seal dispensing machine with a pre-distribution function provided by the present invention has a pre-distribution function. It can pre-distribute seals and distribute them to storage boxes during idle time, and then record the pre-distribution results in a recording device. When a seal extraction request is received, the control device can immediately control the pre-distribution storage device to remove the seal, and no further identification and distribution are required, which reduces the time for identification and distribution. The user can immediately remove the seal after inputting the extraction request, which reduces the seal distribution time and improves the seal distribution efficiency.

[0031] 2. The seal dispensing method provided by the present invention uses the seal dispensing machine with the pre-dispensing function, which can reduce the time for dispensing seals, improve the efficiency of dispensing seals, and better manage seals. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0042] The following combination Figures 1 to 5 The present invention describes a seal dispensing machine with a pre-dispensing function and a seal dispensing method.

[0043] like Figures 1 to 4 As shown, the present invention provides a seal dispensing machine with a pre-distribution function, including multiple cargo lanes 1, a pickup device 3, multiple pre-distribution storage devices 10, a delivery device 9, a recording device and a control device 4.

[0044] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 shown.

[0045] Specifically, the same cargo aisle 1 is used to store the same type of seal, and different cargo aisles 1 can store different types of seals. If the number of seals is large, different cargo aisles 1 can also store the same type of seal. The recording device is used to record the seal models on all cargo aisles 1 and the seal codes of the first seals on all cargo aisles 1. The control device 4 is electrically connected to the pickup device 3, the pre-distribution storage device 10, the delivery device 9 and the recording device respectively.

[0046] Among them, when no seal extraction request is received, the control device 4 controls the picking device 3 to traverse all cargo aisles 1 to be identified, and the control device 4 controls the identification mechanism 32 to identify the seal codes of all the first seals arranged on the cargo aisles 1 to be identified and pass them to the recording device. The picking device 3 transports some of the seals to the storage box 101 and passes the seal codes of the transported seals to the recording device. The specific number of seals of the partial seals depends on the idle status of the storage box 101. For example, if there are three storage boxes 101 without seals, the three seals can be placed in the idle storage boxes 101 in the order of identification. The cargo aisle 1 to be identified is the cargo aisle 1 where the seal code of the first seal is not recorded in the recording device.

[0047] When receiving a seal extraction request, if the seal corresponding to the seal model to be extracted has been placed in the storage box 101, the control device 4 controls the delivery device 9 to remove the seal; if the seal model to be extracted has not been placed in the storage box 101, the control device 4 controls the retrieval device 3 to directly remove the seal.

[0048] The seal dispensing machine with a pre-distribution function provided in this embodiment has a pre-distribution function. It can pre-distribute seals and distribute them to the storage box 101 during idle time, and then record the pre-distribution results in the recording device. When a seal extraction request is received, the control device 4 can immediately control the pre-distribution storage device 10 to take out the seal, and no further identification and distribution are required, which reduces the time for identification and distribution. The user can immediately take out the seal after inputting the extraction request, which reduces the seal distribution time and improves the seal distribution efficiency.

[0049] In some embodiments, the seal dispensing machine also includes a pushing device 2, which is used to push the seal on the cargo aisle 1. The picking device 3 includes a moving mechanism 31, an identification mechanism 32 and a cargo bucket 33. The identification mechanism 32 is arranged on the moving mechanism 31. The identification mechanism 32 is used to identify the first seal arranged on the cargo aisle 1. The cargo bucket 33 is arranged on the moving mechanism 31. Specifically, the pushing device 2 can be a cylinder or a conveyor belt installed under the cargo aisle 1, which can realize the pushing function and is more convenient to use.

[0050] In some embodiments, the seal dispensing machine further includes a frame 5, and multiple cargo lanes 1, a pushing device 2, a pickup device 3, multiple pre-distribution storage devices 10, a recording device and a control device 4 are all arranged on the frame 5, making the structure more stable.

[0051] In some embodiments, the rack 5 is further provided with a display screen 6, a pickup slide 7 and a pickup port 8. The pickup port 8 is connected to the pickup slide 7, making it more convenient to pick up goods.

[0052] In some embodiments, the recognition mechanism 32 is a CCD industrial camera.

[0053] In some embodiments, the moving mechanism 31 includes a lifting component 311, a transverse moving component 312 and a pickup bracket 313. The transverse moving component 312 is connected to the lifting component 311, the pickup bracket 313 is arranged on the transverse moving component 312, and the identification mechanism 32 and the cargo bucket 33 are both arranged on the pickup bracket 313. Specifically, through the cooperation of the lifting component 311 and the transverse moving component 312, the pickup bracket 313 can be driven to move, thereby realizing the movement of the identification mechanism 32 and the cargo bucket 33. The identification mechanism 32 and the cargo bucket 33 can be driven to move to each cargo aisle 1, so that the seal can be obtained more conveniently.

[0054] In some embodiments, the lifting assembly 311 includes a lifting motor 3111, a lifting synchronous belt 3112 and a lifting frame 3113. The lifting synchronous belt 3112 is arranged on the frame 5 in the vertical direction. The lifting frame 3113 is connected to the lifting synchronous belt 3112. The transverse movement assembly 312 is arranged on the lifting frame 3113. After the lifting motor 3111 is started, the lifting synchronous belt 3112 drives the lifting frame 3113 to move up and down, and the movement process is smoother.

[0055] In some embodiments, the transverse movement assembly 312 includes a transverse movement motor 3121, a transverse movement synchronous belt 3122, a transverse movement slide rail 3123 and a transverse movement slider 3124. The transverse movement slide rail 3123 is arranged on the lifting frame 3113, the transverse movement slider 3124 is slidably connected to the transverse movement slide rail 3123, and the picking bracket 313 is arranged on the transverse movement slider 3124. The transverse movement motor 3121 drives the transverse movement slider 3124 to move through the transverse movement synchronous belt 3122, thereby driving the picking bracket 313 to move, and then driving the cargo bucket 33 and the identification mechanism 32 to move, and the movement process is smoother.

[0056] In some embodiments, the picking device 3 also includes a dumping motor 34, which is arranged on the picking bracket 313. The dumping motor 34 is connected to the cargo bucket 33, driving the cargo bucket 33 to push the seal into the delivery device 9 or the storage box 101, which has a higher degree of automation.

[0057] In some embodiments, the lifting motor 3111 and the transverse movement motor 3121 are both stepper motors, which can move the identification mechanism 32 and the cargo bucket 33 more accurately.

[0058] In some embodiments, the pre-distribution storage device 10 includes a storage box 101, a storage motor 103 and a storage baffle 102. The storage box 101 is arranged on the moving mechanism 31. The storage motor 103 is connected to the storage baffle 102 to drive the storage baffle 102 to open or close the storage box 101, thereby realizing the function of temporary storage and the function of lowering the seal to the delivery device 9.

[0059] In some embodiments, the delivery device 9 includes a delivery box 91 and a delivery conveyor belt 92. The number of storage boxes 101 is multiple. The delivery box 91 is arranged on one side of the storage box 101. The delivery box 91 is provided with a delivery channel. The delivery conveyor belt 92 is located below the storage box 101 and the delivery box 91. Specifically, when a seal extraction request is received, if there is no corresponding seal in the storage box 101, the picking device 3 goes to the cargo aisle 1 to take the corresponding seal. The seal passes through the delivery channel in the delivery box 91 and falls to the delivery conveyor belt 92. The delivery conveyor belt 92 transports the seal to the pickup port 8, thereby completing the pickup, and will not interfere with the work of the storage box 101, with a higher degree of intelligence.

[0060] like Figure 5 As shown, the present invention also provides a seal dispensing method, which uses the seal dispensing machine with the pre-dispensing function to distribute seals, including the following steps:

[0061] S1. Pre-distribution: The control device 4 controls the pickup device 3 to traverse all aisles 1 to be identified, and controls the identification mechanism 32 to identify the seal codes of the first seals arranged in the aisles 1 to be identified and transmit them to the recording device. The pushing device 2 and the pickup device 3 push some seals into the storage box 101 and transmit the seal codes of the pushed seals to the recording device.

[0062] S2. Pick up the seal. If the seal corresponding to the seal model to be picked up has been placed in the storage box 101, the control device 4 controls the delivery device 9 to take out the seal. If the seal code of the first seal corresponding to the seal model to be picked up has been recorded by the recording device and has not been placed in the storage box 101, the control device 4 controls the picking device 3 and the pushing device 2 to take out the seal. If the seal code of the first seal corresponding to the seal model to be picked up has not been recorded by the recording device and has not been placed in the storage box 101, the control device 4 controls the picking device 3 to move to the cargo aisle 1 where the corresponding seal model is located, and the control device 4 controls the identification mechanism 32 to identify the seal code of the first seal in the cargo aisle 1. Then, the control device 4 controls the picking device 3 and the pushing device 2 to take out the seal.

[0063] When no seal extraction request is received, step S1 is executed; when a seal extraction request is received, step S2 is executed.

[0064] The seal dispensing method provided in this embodiment uses the above-mentioned seal dispensing machine with a pre-dispensing function, which can reduce the time for dispensing seals, improve the efficiency of dispensing seals, and better manage seals.

[0065] In this embodiment, the pre-distribution function of the seal dispensing machine can be used to control the distribution time to about 5 seconds. Specifically, the pre-distribution function means that when the seal dispensing machine is idle, the seal inside the seal dispensing machine is automatically identified, the seal number is recorded after successful identification, and the successfully identified seal is placed in the storage box 101 of the seal dispensing machine before distribution. When the seal dispensing machine receives the distribution instruction, it directly opens the storage box 101 that has been completed for identification, and can take out the seal in a short time. Among them, the idle time refers to the time when the seal dispensing machine currently has no distribution tasks.

[0066] In some embodiments, in step S1, when the operating environment of the seal dispensing machine reaches the pre-distribution conditions, each time a seal is identified, it is checked whether there is a missing seal in the storage box 101. If there is a missing seal in the storage box 101, the successfully identified seal will be placed in the storage box 101, which improves the distribution efficiency.

[0067] In some embodiments, in step S1, one of the cargo lanes 1 in the seal dispensing machine for which no identification result has been obtained is selected for identification, which is more intelligent.

[0068] In some embodiments, in step S1, after completing one identification, it is checked whether there is a storage box 101 of this seal type in the result of successful identification in the seal dispensing machine and there is no seal in the storage box 101. If there is a storage box 101 without this seal type, the seal is poured into the storage box 101; otherwise, the next identification process is executed, which is more intelligent.

[0069] In some embodiments, in step S1, if all storage boxes 101 are equipped with seals and the cargo channel 1 in the seal dispenser is identified, the identification is stopped and the pre-distribution process is ended, which is more intelligent.

[0070] In some embodiments, in step S1, if seal recognition fails continuously and aisle 1 has reached the recycling number, recognition is stopped and the pre-distribution process is ended, which is more intelligent.

[0071] In some embodiments, when the driver picks up the seal, if the required seal exists in the storage box 101, after the seal in the storage box 101 is dispatched, the pushing device 2 and the picking device 3 will refill the storage box 101 with the same type of seal, which is more intelligent.

[0072] In some embodiments, when step S1 is being executed, if the seal distribution receives a retrieval request, step S1 is immediately terminated and step S2 is executed, which is more intelligent.

[0073] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
