Description

Technical Field

[0001] The present invention relates to the field of logistics and transportation technology, and more specifically, to a large-scale logistics express automatic marking device. Background Art

[0002] Large express parcels often refer to logistics express parcels that are large in size and heavy in weight. In order to reasonably adapt to the transportation vehicles during transportation, such logistics express parcels need to be marked, so that the express company can arrange logistics transport vehicles with larger carrying capacity for transportation.

[0003] A Chinese invention patent with publication number CN114851720A discloses an automatic marking device suitable for large-scale logistics express parcels. The device uses a printing plate to contact the large-scale logistics express parcels for marking and printing. However, during this process, the express parcels will move relative to the printing block due to movement. If the express parcels are not stopped, the hard brush will become blurred. If the transportation of the express parcels is stopped, the working efficiency of the equipment will be affected. Summary of the invention

[0004] The invention provides a large-scale logistics express automatic marking device, which aims to solve the problem that the printing structure in the existing marking device cannot move synchronously with the express, resulting in low marking efficiency.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic marking device for large-scale logistics express parcels, including a conveyor, which can select a commonly used conveyor belt structure to convey large-scale logistics express parcels, a marker is arranged above the conveyor, and the marker is used to mark the express parcels, a guide plate is fixedly installed above the conveyor through a support frame, and the support frame is connected to the frame structure of the conveyor without affecting the transportation of the express parcels, a follow-up guide groove is arranged in the inner wall of the guide plate, a telescopic frame is connected to the top of the marker, a guide column is installed on the telescopic frame, and the guide column is slidably installed in the follow-up guide groove, and the guide plate can be set as a group. At this time, the follow-up guide groove is required to guide the guide column while limiting it. In order to ensure the stability of the mechanism, the guide plates can be set as two groups and arranged parallel to each other so that the telescopic frame is located in the two guide plates, and the follow-up guide groove includes It includes a reset guide groove, a lifting guide groove, a lifting guide groove and a falling guide groove which are connected in sequence from head to tail. The lifting guide groove is inclined upward at one end away from the horizontal guide groove, and the reset guide groove is inclined downward at one end away from the lifting guide groove, and is connected to the top of the falling guide groove. An electric lock is provided on the top of the follow-up guide groove. When the electric lock is extended into the falling guide groove, the guide column is blocked. A guide column lifting assembly is provided at the lifting guide groove. The guide column lifting assembly is used to lift the guide column from the horizontal guide groove along the lifting guide groove to the reset guide groove, and then slide the guide column to the top of the falling guide groove through the reset guide groove and be blocked by the electric lock. The conveyor controls the express to be transported from the falling guide groove to the lifting guide groove. A resistance pressure plate is fixedly installed on the outside of the marker, and a cleaner is provided on the conveyor at a position close to the side of the guide plate where the express enters. The cleaner cleans the top surface of the express when the express passes.

[0006] In a preferred embodiment, a photoelectric sensor is provided above the conveyor. The photoelectric sensor is fixedly mounted on the support frame and is used to sense the express entering the bottom of the guide plate. The electric lock is a block structure slidably mounted in the guide plate. The block structure is driven by a linear motor and moves laterally, so that the block can be automatically controlled to enter or move out of the falling guide groove, thereby realizing the locking and unlocking control of the guide column. After the express enters the specified position at the bottom of the guide plate, it is sensed and identified by the photoelectric sensor, and the linear motor can be controlled to pull out the block to release the guide column.

[0007] In a preferred embodiment, the guide column lifting assembly is a belt assembly, which is arranged in the guide plate and parallel to the lifting guide groove. The outside of the belt assembly is fixedly connected to the lifting plate. The belt is driven by the rotation of the pulley in the belt assembly, and then the lifting plate is driven to move from bottom to top in the lifting guide groove, thereby lifting the guide column. At the same time, the lifting plate is tilted downward away from the end of the belt assembly so that when the guide column reaches the reset guide groove, it can automatically slide into the reset guide groove.

[0008] The telescopic frame includes a sleeve rod and a sliding rod. The guide column is fixedly installed on the outside of the sleeve rod, and the sliding rod is slidably inserted into the inside of the sleeve rod. The sleeve rod is fixedly installed on the top of the guide plate. In actual use, the sliding rod can slide up and down to make the marker and the resistance pressure plate adaptively carry express boxes of different heights, thereby improving the adaptability of the equipment.

[0009] In a preferred embodiment, the marker includes a shell connected to the telescopic frame, that is, the shell is fixedly connected to the guide column, a printing plate is arranged inside the marker, an ink supply tube is arranged on the printing plate, and the ink supply tube extends out of the telescopic frame.

[0010] In a preferred embodiment, support plates are provided on all four sides of the interior of the shell, the top of the support plates is rotatably installed in the shell, the bottom of the support plates is arranged in an arc shape and is inclined toward the outside of the shell, and a spring is arranged between the support plates and the shell. The spring provides an elastic force for the support plates to rotate toward the center of the shell, that is, when not in contact with the express, each support plate maintains the state shown in the figure, and then in the process of the marker falling, the support plates will first contact the surface of the express and gradually flip outward under the action of pressure, at which time the position to be marked can be flattened.

[0011] In a preferred embodiment, the top of the printing plate is slidably inserted into the outer shell, and a tension spring is connected between the printing plate and the outer shell. The tension spring provides an upward elastic force to the printing plate, and the elastic force pulls the printing plate up when the spring leaf is freely stretched, that is, a pull rope is connected between the bottom of the supporting plate and the outer wall of the printing plate, so that when the supporting plate contacts the express and flattens the express, the printing plate is also pulled down to make it contact with the surface of the express.

[0012] In a preferred embodiment, a buffer plate is provided at the bottom of the resistance pressure plate, and the bottom wall of the buffer plate and the bottom wall of the resistance pressure plate are both provided with resistance-increasing patterns. A buffer member is provided between the buffer plate and the resistance pressure plate, and the buffer member includes a gas tank, which is fixedly mounted on the resistance pressure plate. A connecting rod is fixedly connected to the top of the buffer plate, and the top of the connecting rod extends into the gas tank and is fixedly connected to a piston. The piston is slidably mounted in the gas tank, and an air hole is opened on the top of the piston. The air hole is a micro hole. When the resistance pressure plate falls, the buffer plate contacts the express first, thereby causing the piston to rapidly compress the top space of the gas tank. At this time, the gas cannot flow out of the air hole quickly, thereby producing a buffering effect.

[0013] In a preferred embodiment, the cleaner includes a cleaning frame, which is fixedly installed above the conveyor. A movable opening is provided on the side of the cleaning frame close to the guide plate. A flap is rotatably installed inside the cleaning frame. The bottom end of the flap extends out of the cleaning frame from the movable opening. A brush rod is fixedly connected to the bottom of the flap. When the express passes through the cleaning frame, the flap will be lifted up so that the brush rod reaches the surface of the express. As the express moves forward, the brush rod can be used to clean the top surface of the express.

[0014] In a preferred embodiment, a blower mechanism is installed inside the cleaner and is located on the side of the flap away from the guide plate. When the express passes through the cleaning rack, air is blown toward the flap. The airflow flows downward along the flap and blows toward the contact position between the brush rod and the surface of the express, thereby blowing out debris and improving the cleaning effect.

[0015] Technical effects and advantages of the present invention:

[0016] The present invention uses a follow-up guide groove to guide the guide column. When the express passes under the guide plate, the marker automatically slides down and contacts the surface of the express to perform a marking operation. The resistance pressure plate is attached to the top of the express to form a resistance, so that the marker moves forward with the express, increasing the contact time between the marker and the surface of the express, improving the effect of marking printing, and realizing a stable and effective marking operation without stopping the express, thereby improving the clarity of the marking and increasing the practicality of the equipment.

[0017] When the resistance plate falls, the buffer plate first contacts the express, so that the piston sharply compresses the top space of the gas tank, generating a buffering effect, reducing the impact of the marker and the resistance plate, and then the gas slowly flows out, the support plate flattens the position to be marked, and at the same time pulls the printing plate down to make it contact with the surface of the express, thereby avoiding printing shaking caused by the sudden downward movement of the telescopic frame and the marker, and also making the printing plate gradually approach the surface of the express to print after the marker starts to contact the express and moves with the express, avoiding blurring of the printing caused by the marker not keeping up with the speed at the initial contact;

[0018] When the express item passes through the cleaning rack, the flap is lifted up to allow the brush rod to reach the surface of the express item. As the express item moves forward, the brush rod can be used to clean the top surface of the express item to avoid being affected during printing. At the same time, the blower blows air toward the flap, and the airflow flows downward along the flap and blows toward the contact position between the brush rod and the surface of the express item, thereby blowing out debris and improving the cleaning effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 creative work are within the scope of protection of the present invention. Example 1

[0029] Refer to the instruction manual Figure 1 A large-scale logistics express automatic marking device includes a conveyor 1. The conveyor 1 can select a commonly used conveyor belt structure to convey large-scale logistics express. A marker 4 is arranged above the conveyor 1. The marker 4 is used to mark the express. A guide plate 2 is fixedly installed above the conveyor 1 through a support frame 11. The support frame 11 is connected to the frame structure of the conveyor 1 and does not affect the transportation of the express. A follow-up guide groove 21 is arranged in the inner wall of the guide plate 2. A telescopic frame 3 is connected to the top of the marker 4. A guide column 31 is installed on the telescopic frame 3. The guide column 31 is slidably installed in the follow-up guide groove 21. The guide plate 2 can be set as a group. At this time, the follow-up guide groove 21 is required to guide the guide column 31 while also limiting it. In order to ensure the stability of the mechanism, the guide plate 2 can be set as two groups and arranged in parallel with each other so that the telescopic frame 3 is located in the two guide plates 2. Figure 2As shown, the follow-up guide groove 21 includes a reset guide groove 211, a lifting guide groove 212, a lifting guide groove 212 and a falling guide groove 214 which are connected in sequence from head to tail. The end of the lifting guide groove 212 away from the horizontal guide groove 213 is inclined upward, and the end of the reset guide groove 211 away from the lifting guide groove 212 is inclined downward and connected to the top of the falling guide groove 214. An electric lock buckle 22 is provided at the top of the follow-up guide groove 21. When the electric lock buckle 22 extends into the falling guide groove 214, it blocks the guide column 31. A guide column lifting assembly is provided at the lifting guide groove 212. The guide column lifting assembly is used to move the guide column 31 from the horizontal guide groove 213 to the falling guide groove 214. The guide post 31 is then slid from the guide groove 213 along the lifting guide groove 212 to the reset guide groove 211, and then the guide post 31 is slid through the reset guide groove 211 to the top of the falling guide groove 214, and is blocked by the electric lock 22. The conveyor 1 controls the express to be transported along the falling guide groove 214 to the lifting guide groove 212. A resistance pressure plate 5 is fixedly installed on the outside of the marker 4. A cleaner 6 is provided on the conveyor 1 at a position close to the side where the express enters the guide plate 2. The cleaner 6 cleans the top surface of the express when the express passes through. In actual use, the conveyor 1 transports large logistics express, and in the initial state, such as Figure 4 As shown, the guide post 31 is located at the top of the falling guide groove 214 and is locked by the electric lock 22. The marker 4 is higher than the height of the express. When the express passes under the guide plate 2, the electric lock 22 is controlled to leave the falling guide groove 214, unlocking the guide post 31, and the telescopic frame 3 and the marker 4 automatically slide down. The marker 4 contacts the surface of the express to perform the marking operation, and the resistance pressure plate 5 is attached to the top of the express to form resistance, so that the marker 4 moves forward with the express, increasing the contact time between the marker 4 and the surface of the express, and improving the effect of marking printing. Until the guide post 31 reaches the lifting guide groove 212, the guide post The lifting assembly lifts the guide column 31 from the horizontal guide groove 213 along the lifting guide groove 212 to the reset guide groove 211. At this time, the marker 4 moves forward and rises until it leaves the express. During the process, the marker 4 and the express will not be displaced, and the mark will not be damaged or blurred. Then the guide column 31 slides to the top of the falling guide groove 214 through the reset guide groove 211 and is blocked again by the electric lock 22, waiting for the next express to pass by for marking. This cycle can achieve stable and effective marking operations without stopping the express, thereby improving the clarity of the marking and increasing the practicality of the equipment.

[0030] like Figure 1 and Figure 4As shown, a photoelectric sensor 7 is provided above the conveyor 1. The photoelectric sensor 7 is fixedly mounted on the support frame 11 and is used to sense the express entering the bottom of the guide plate 2. The photoelectric sensing switch technology based on sensing and identifying the position of the object has been maturely used. The selection of the photoelectric sensor 7 and other information are not described in detail in this embodiment. The electric lock 22 is a block structure slidably mounted in the guide plate 2. The block structure is driven by a linear motor and moves laterally, so that the control block can automatically enter or move out of the falling guide groove 214 to achieve locking and unlocking control of the guide column 31. After the express enters the specified position at the bottom of the guide plate 2, it is sensed and identified by the photoelectric sensor 7, and the linear motor can be controlled to pull out the block to release the guide column 31.

[0031] like Figure 3 As shown, the guide column lifting assembly is a belt assembly 23, and the belt assembly 23 is arranged in the guide plate 2, and the belt assembly 23 is arranged parallel to the lifting guide groove 212. The outside of the belt assembly 23 is fixedly connected with a lifting plate 24. The belt is driven by the rotation of the pulley in the belt assembly 23, and then the lifting plate 24 is driven to move from bottom to top in the lifting guide groove 212, so as to realize the lifting of the guide column 31. At the same time, the lifting plate 24 is tilted downward away from the end of the belt assembly 23, so that when the guide column 31 reaches the reset guide groove 211, it can automatically slide into the reset guide groove 211.

[0032] Since the descending height of the guide pillar 31 is fixed, but the height of the express items varies, the present embodiment also provides the following solutions: Figure 1 As shown, the telescopic frame 3 includes a sleeve rod 32 and a slide rod 33, the guide column 31 is fixedly installed on the outside of the sleeve rod 32, the slide rod 33 is slidably inserted into the inside of the sleeve rod 32, and the sleeve rod 32 is fixedly installed on the top of the guide plate 2. In actual use, the slide rod 33 slides up and down, so that the marker 4 and the resistance pressure plate 5 can adaptably carry express boxes of different heights, thereby improving the adaptability of the equipment.

[0033] like Figure 8 As shown, the marker 4 includes a shell 41, and the shell 41 is connected to the telescopic frame 3, that is, the shell 41 is fixedly connected to the guide column 31, and a printing plate 42 is arranged inside the marker 4, and an ink supply tube is arranged on the printing plate 42, and the ink supply tube extends out of the telescopic frame 3. The marking principle of the shell 41 adopted in this embodiment is the same as a printing plate structure and printing principle in an automatic marking device for large-scale logistics express disclosed in a Chinese invention patent with publication number CN114851720A, and both adopt ink supply to the marking printing structure for marking and printing.

[0034] In this embodiment, the implementation scenario is specifically as follows: the falling guide groove 214, the horizontal guide groove 213, the lifting guide groove 212 and the reset guide groove 211 are used for guidance, and the conveyor 1 conveys large logistics express parcels, and in the initial state, the guide column 31 is located at the top of the falling guide groove 214 and is locked by the electric lock 22. When the express parcel passes under the guide plate 2, the electric lock 22 is controlled to unlock, and the telescopic frame 3 and the marker 4 automatically slide down, and the marker 4 contacts the surface of the express parcel for marking, and the resistance pressure plate 5 is attached to the top of the express parcel to form resistance, so that the marker 4 moves forward with the express parcel, increasing the contact time between the marker 4 and the surface of the express parcel, and improving the effect of marking printing, until the guide column 31 reaches the lifting plate 214. When the express is at the guide groove 212, the guide column 31 is lifted from the horizontal guide groove 213 along the lifting guide groove 212 to the reset guide groove 211 by the guide column lifting assembly, and the guide column 31 is lifted by the lifting plate 24, so that the telescopic frame 3 and the marker 4 move forward and rise until they leave the express. During the process, the marker 4 and the express will not be displaced, and the mark will not be damaged or blurred. Then the guide column 31 slides to the top of the falling guide groove 214 through the reset guide groove 211 and is blocked again by the electric lock 22, waiting for the next express to pass by for marking operation. In this cycle, stable and effective marking operations can be achieved without stopping the express, thereby improving the clarity of the mark and increasing the practicality of the equipment. Example 2

[0035] Due to the natural fall of the marker 4 and the resistance plate 5, a certain impact will be generated. In order to protect the express and improve the printing effect, this embodiment provides the following solution: a large-scale logistics express automatic marking device based on embodiment 1, such as Figure 8 and Fig. 9 As shown, support plates 43 are arranged around the inner side of the housing 41. The top of the support plates 43 is rotatably mounted in the housing 41. The bottom of the support plates 43 is arranged in an arc shape and is inclined toward the outer side of the housing 41. A spring 44 is arranged between the support plates 43 and the housing 41. The spring 44 provides elastic force for the support plates 43 to rotate toward the center of the housing 41. That is, when not in contact with the express, each support plate 43 maintains Fig. 9 In the state shown, during the falling process of the marker 4, the supporting plate 43 will first contact the surface of the express and gradually flip outward under the action of pressure. At this time, the position to be marked can be flattened to make the printing more stable.

[0036] like Figure 8 and Fig. 9 As shown, the top of the printing plate 42 is slidably inserted into the housing 41, and a tension spring 45 is connected between the printing plate 42 and the housing 41. The tension spring 45 provides an upward elastic force for the printing plate 42, and the elastic force pulls the printing plate 42 upward when the spring leaf 44 is freely stretched, that is, Figure 8As shown, a pull rope 46 is connected between the bottom of the supporting plate 43 and the outer wall of the printing plate 42, so that when the supporting plate 43 contacts the express and flattens the express, the printing plate 42 is also pulled down to make it contact with the surface of the express, thereby avoiding printing shaking caused by the sudden downward movement of the telescopic frame 3 and the marker 4, and also when the marker 4 starts to contact the express and follows the movement of the express, the printing plate 42 gradually approaches the surface of the express to print, avoiding the marker 4 not being able to keep up with the speed during the initial contact and causing blurred printing.

[0037] like Figure 8 and Fig. 9 As shown, a buffer plate 51 is arranged at the bottom of the resistance pressure plate 5, and the bottom wall of the buffer plate 51 and the bottom wall of the resistance pressure plate 5 are both provided with resistance-increasing patterns, and a buffer member 52 is arranged between the buffer plate 51 and the resistance pressure plate 5, and the buffer member 52 includes a gas tank 521, and the gas tank 521 is fixedly installed on the resistance pressure plate 5, and the top of the buffer plate 51 is fixedly connected to a connecting rod 522, and the top of the connecting rod 522 extends into the gas tank 521 and is fixedly connected to a piston 523, and the piston 523 is slidably installed in the gas tank 521, and the piston 523 is fixedly connected to the gas tank 521. An air hole 524 is opened on the top, and the air hole 524 is a micro hole, that is, when the resistance pressure plate 5 does not contact the surface of the express, the buffer plate 51 is located at a lower position. When the resistance pressure plate 5 falls, the buffer plate 51 contacts the express first, so that the piston 523 sharply compresses the top space of the gas tank 521. At this time, the gas cannot flow out of the air hole 524 quickly, which can produce a buffering effect, reduce the impact of the marker 4 and the resistance pressure plate 5, and play a safety protection role. After that, the gas flows out slowly, and the resistance pressure plate 5 and the marker 4 can be completely fitted with the surface of the express.

[0038] In this embodiment, the implementation scenario is specifically as follows: by setting a supporting plate 43 in the shell 41 and setting a buffer plate 51 under the resistance pressure plate 5, when the resistance pressure plate 5 falls, the buffer plate 51 first contacts the express, so that the piston 523 sharply compresses the top space of the gas tank 521. At this time, the gas cannot flow out quickly from the air hole 524, which can produce a buffering effect, reduce the impact of the marker 4 and the resistance pressure plate 5, and play a safety protection role. After that, the gas flows out slowly, and the supporting plate 43 gradually flips outward under the pressure after contacting the surface of the express. At this time, the position to be marked can be flattened to make the printing more stable. At the same time, the supporting plate 43 also pulls down the printing plate 42 to make it contact with the surface of the express, thereby avoiding printing shaking caused by the sudden downward movement of the telescopic frame 3 and the marker 4, and also makes the marker 4 start to contact the express and follow the movement of the express before the printing plate 42 gradually approaches the surface of the express for printing, so as to avoid the marker 4 not being able to keep up with the speed during the initial contact and causing blurred printing. Example 3

[0039] During the transportation of express mail, a lot of dust or debris will adhere to the surface, which will affect the printing of the express mail later. Therefore, this embodiment provides the following solution: a large-scale logistics express mail automatic marking device based on embodiment 1, such as Figure 4 and Figure 5 As shown, the cleaner 6 includes a cleaning frame 61, which is fixedly installed above the conveyor 1. A movable opening is provided on the side of the cleaning frame 61 close to the guide plate 2. A flap 62 is rotatably installed inside the cleaning frame 61. The bottom end of the flap 62 extends out of the cleaning frame 61 from the movable opening. A brush rod 63 is fixedly connected to the bottom of the flap 62. When the express passes through the cleaning frame 61, the flap 62 will be lifted up to allow the brush rod 63 to reach the surface of the express. As the express moves forward, the brush rod 63 can be used to clean the top surface of the express to avoid being affected during printing.

[0040] like Figure 4 As shown, a blower mechanism 64 is installed inside the cleaner 6, and the blower mechanism 64 is located on the side of the flap 62 away from the guide plate 2. When the express passes through the cleaning rack 61, the blower mechanism 64 blows air toward the flap 62, and the air flow flows downward along the flap 62 and blows toward the contact position between the brush rod 63 and the surface of the express, so that the debris can be blown out and the cleaning effect is improved.

[0041] In this embodiment, the implementation scenario is specifically as follows: by setting a flap 62 on the conveyor 1, when the express passes through the cleaning rack 61, the flap 62 will be lifted up to allow the brush rod 63 to reach the surface of the express. As the express moves forward, the brush rod 63 can be used to clean the top surface of the express to avoid being affected during printing. At the same time, 64 blows air toward the flap 62, and the airflow flows downward along the flap 62 and blows toward the contact position between the brush rod 63 and the surface of the express, so that debris can be blown out to improve the cleaning effect.

[0042] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
