Description

Technical Field

[0001] This article belongs to the technical field of material basket movement in production lines, and specifically relates to an automatic frame-spitting device based on photoelectric monitoring. Background Art

[0002] With the rapid development of the civil aviation industry, the number of passengers traveling by air has increased year by year, so manual baggage check-in services can no longer meet the requirements. In order to simplify the manual baggage check-in process of airlines, self-service baggage check-in equipment has also emerged as self-service check-in and mobile check-in are increasingly widely used in airports around the world.

[0003] Usually when passengers check in their luggage, they need to place it on a conveyor belt for transportation. However, in order to prevent the luggage from being damaged due to scratches, a material frame tray is placed under the luggage to support the luggage. However, there is no one to place the material frame near the conveyor belt, so generally a separate staff member is required to perform manual operation at the end of the conveyor belt.

[0004] In order to meet the requirements of automated unmanned operation, there is an automatic frame-dispensing device that can dispense empty frames again according to whether there are still material frames on the belt conveyor. However, most of the existing automatic frame-dispensing devices only arrange the material frames in a row, and then use the conveyor belt to send the material frames to the loading area in sequence. This form will make the length of the entire automatic frame-dispensing device very long, and during a long period of operation, the material frames will be used up quickly, and it is necessary to manually arrange the material frames in sequence, which is extremely cumbersome and occupies too much production area.

[0005] When the material frames are empty, they are mostly stacked up and down to effectively reduce the space occupied. Therefore, in order to adapt to the stacked material frames and to be able to spit out the frames smoothly, a truss gantry crane type of equipment is used to take down the material frames from the top one by one, so as to realize the spitting out operation of the material frames. However, this form will make the height of the entire spitting out equipment very high, and the linked mechanical structure is also very complicated. Both daily maintenance and the writing and modification of automation programs are very complicated. Therefore, an automatic spitting out equipment that can spit out the frames stably and efficiently and has a simple structure and is easy to maintain is needed. Utility Model Content

[0006] In order to solve the above problems, this paper proposes an automatic frame-spitting device based on photoelectric monitoring, the automatic frame-spitting device includes a main frame and a shift roller assembly, the inner bottom of the main frame is longitudinally provided with a shift roller assembly, the outlet end of the main frame is provided with a discharge conveyor belt, the inner side of the main frame is provided with a photoelectric detection assembly, a lifting assembly and a clamping and fixing assembly, the lifting assembly is horizontally arranged between the shift roller assemblies, the clamping and fixing assembly is arranged at the middle of both sides of the main frame through an electric control box, the electric control box is inside the left and right sides of the main frame of a left-right symmetrical type, a clamping and fixing assembly is arranged on the top surface of the electric control box, a shift roller assembly is longitudinally arranged between the two electric control boxes, photoelectric detection assemblies are arranged at the front and rear ends of the inner side of the electric control box, the inner surface of the electric control box is symmetrically provided with a lifting guide groove, and a lifting guide groove of the electric control box is provided inside Detection site, a translation detection site is provided on the upper surface of the electric control box, the clamping and fixing components are linked to each other through the inner side of the electric control box and the bottom of the shift roller component, the lifting detection site is arranged on the outer side of the end of the lifting component, and the translation detection site is arranged on the outer side of the end of the clamping and fixing component. By using the mutual linkage and cooperation of the photoelectric detection component, the lifting component and the clamping and fixing component, the upper-taking frame-spitting form that originally needs to clamp the stacked material frame from top to bottom is changed to a falling frame-spitting form that is fixed at the top and detached from the bottom. In this way, the mechanical structure of the frame-spitting device can be greatly simplified, and there is no need to continuously adjust the clamping height of the upper clamp according to the height of the stacked material box. Through a few simple detection sites, the overall cyclic frame-spitting linkage can be realized, which is simple and efficient, and reduces the cost of writing and debugging the linkage program and mechanical maintenance.

The feed infrared photoelectric and the discharge infrared photoelectric are both arranged inside the electric control box, and the feed infrared photoelectric and the discharge infrared photoelectric are both directed toward the middle of the main frame through the photoelectric opening. The electric control boxes arranged on both sides can conveniently arrange the photoelectric detection components, lifting components and clamping and fixing components between the electric control boxes on both sides, which can minimize the layout space required for the electric control box, and can also facilitate the internal hiding of the photoelectric detection components, lifting components and clamping and fixing components, and hide the transmission components that may injure people inside the electric control box to improve the integrity of the overall equipment.

[0009] The lifting assembly includes a lifting motor, a lifting frame and a lifting linkage shaft. The lifting frame is an X-shaped cross-arm lifting frame. Lifting surfaces are provided on the front and rear sides of the lifting frame. A lifting linkage shaft is penetrated through the middle of the left end of the lifting frame. The lifting surfaces are arranged between the shift roller assemblies. The ends of the lifting linkage shaft are connected to the lifting motor through a belt. The lifting motor is transversely arranged between the shift roller assemblies. The left end of the lifting motor is connected to the lifting linkage shaft through an output pulley. The lifting assembly can move both the stacked material boxes and the single material box up and down, thereby realizing the actual spitting effect of the material box, and the lifting detection position in the lifting assembly can accurately locate the lifting height of the lifting frame, thereby realizing the linkage control of the lifting assembly.

[0010] The clamping and fixing assembly includes a clamping motor, a clamping transmission belt, an active clamping plate, a driven clamping plate and a translation slide. The surface of the active clamping plate is horizontally provided with a strip waist hole, and the output shaft of the clamping motor passes through the strip waist hole and is arranged above the active clamping plate. The clamping motor is connected to the active clamping plate through a rotation and translation change-of-direction assembly, and the bottom end of the output shaft of the clamping motor is connected to the driven clamping plate through a clamping transmission belt. A rotation and translation change-of-direction assembly is provided at the bottom of the driven clamping plate, and the driven clamping plate is connected to the clamping transmission belt through a rotation and translation assembly. The bottom of both ends of the active splint and the driven splint are both laterally provided with translation slides, the inner sides and front ends of the active splint and the driven splint are both protruding with clamping tips, and the rear end of the active splint is provided with a transverse translation detection position, which realizes the function of lifting and supporting the stacked material box through the clamping and fixing assembly, and the entire stacked material box can be suspended above the roller assembly, which can not only achieve the effect of spitting out the material box from the bottom, but also can achieve the effect of detaching a single material box from the bottom through linkage with the lifting assembly.

[0011] The rotational translational changing component includes a gear, a rack, a transmission shaft, a bearing seat and a pulley, a gear is provided at one end of the transmission shaft, a pulley is provided at the other end of the transmission shaft, a bearing seat is provided in the middle of the transmission shaft, the bearing seat is fixedly connected to the inside of the electric control box through a bracket, the gear is meshed with the rack, the rack is fixedly connected to the bottom of the active splint and the driven splint, the gear under the active splint is connected to the output shaft of the clamping motor through the strip waist hole on the surface of the active splint, and the rotation of the motor can be converted into a translational movement form through the rotational translational changing component, thereby realizing the lateral translation of the active splint and the driven splint.

[0014] The outer surface of the electric control box and the outer surface of the upper end are both provided with acrylic transparent plates, which are intuitive and beautiful for maintenance and observation.

[0015] Beneficial effects:

[0016] By using the mutual linkage of photoelectric detection components, lifting components and clamping and fixing components, the upper-taking frame-dispensing form that originally required clamping the stacked material frame from top to bottom is changed to a lower-falling frame-dispensing form that is fixed at the top and released at the bottom. This can greatly simplify the mechanical structure of the frame-dispensing device, and there is no need to continuously adjust the clamping height of the upper clamp according to the height of the stacked material box. The overall cyclic frame-dispensing linkage can be achieved through a few simple detection points, which is simple and efficient, and reduces the cost of writing and debugging the linkage program and mechanical maintenance.

[0017] The frame-type main frame can conveniently allow a portion of the raised stacked material box to exceed the top surface of the main frame, which has sufficient flexibility. The frame can also facilitate the setting of the electric control boxes on both sides and the front and rear sections of the feed and discharge ports, increasing the flexibility of the overall assembly combination.

[0018] The electric control boxes arranged on both sides can conveniently arrange the photoelectric detection components, lifting components and clamping and fixing components between the electric control boxes on both sides, which can minimize the layout space required for the electric control boxes and facilitate the internal hiding of the photoelectric detection components, lifting components and clamping and fixing components. The transmission components that may cause harm to people can be hidden inside the electric control box to improve the integrity of the overall equipment.

[0019] The lifting component can move both stacked material boxes and single material boxes up and down, thereby realizing the actual frame-spitting effect of the material box, and the lifting detection point in the lifting component can accurately locate the lifting height of the lifting frame, thereby realizing the linkage control of the lifting component.

[0020] The stacked material boxes can be lifted and supported by the clamping and fixing components, and a whole stack of material boxes can be suspended above the roller assembly, which can not only spit out the material boxes from below, but also achieve the effect of detaching a single material box from below through linkage with the lifting component.

[0021] The rotation of the motor can be changed into a translational movement by means of the rotational translational change-of-direction assembly, thereby realizing the lateral translation of the active clamping plate and the driven clamping plate.

[0022] The three sets of trigger points at the lifting detection site can respectively realize the heights of three different functional positions: sinking under the transfer roller assembly, taking out the bottom material box, and receiving the downward movement of the top stacked material box, for positioning and linkage, and at the same time, they are linked with the two trigger points of the translation detection site, so as to achieve precise control and sensing of each step.

[0031] Implementation examples;

[0032] Before use, the stacked material boxes are pushed into the feed port of the main frame 1 by a trolley. The stacked material boxes enter the interior of the main frame 1 through the roller assembly and trigger the feeding infrared photoelectric device 3 at the same time. When the feeding infrared photoelectric device 3 closes again to receive after a material box enters, it indicates that a material box has entered and the subsequent linkage device is started for operation. If the height-limiting infrared photoelectric device 4 is also triggered when the material box enters, the linkage of the subsequent device is stopped and an alarm is issued.

[0033] When the stacked material boxes enter the main frame 1, the lifting motor 6 is first triggered, and the lifting motor 6 lifts the lifting frame 7 through the lifting linkage shaft 15, and the lifting frame 7 is lifted together with the stacked material boxes. When the lifting frame 7 rises to the upper part, it triggers the trigger point below the highest trigger point in the lifting detection position 14, and the clamping motor 8 starts to start at this time. The clamping motor 8 simultaneously moves the active splint 10 and the driven splint 11 inward along the translation slide 12 through the rotating translation reversing component and the clamping transmission belt 9. The clamping tips on the inner sides of the active splint 10 and the driven splint 11 clamp the side edges and holes on both sides of the inserted stacked material boxes, thereby lifting the stacked material boxes through the active splint 10 and the driven splint 11. However, at this time, since the lifting frame 7 is not raised to the highest point, the active splint 10 and the driven splint 11 The plate 11 clamps the material box above the material box at the bottom layer of the stacked material boxes. Therefore, the material box at the bottom layer of the stacked physical box is not fixedly clamped by the active clamp 10 and the driven clamp 11. Therefore, when the active clamp 10 triggers the translation detection position 13 to complete the clamping of the stacked physical box, the lifting frame 7 moves down to take out the material box at the lowest layer and place it on the shift roller assembly. When the lifting frame 7 triggers the trigger point at the lower end of the lifting detection position 14, it means that the material box is completely placed on the shift roller assembly. The material box is moved out of the main frame 1 through the shift roller assembly and the discharge conveyor belt 2, and the discharge infrared photoelectric 5 is triggered at the same time. When the discharge infrared photoelectric 5 has a material box moved out through the discharge conveyor belt 2, it closes again to receive and also receives subsequent instructions for spitting out the frame, it begins to prepare for normal spitting out of the frame.

[0034] The lifting frame 7 rises to the highest trigger point of the lifting detection position 14. At this time, the top surface of the lifting frame 7 just contacts with the lifted bottom surface of the stacked material box. At this time, the active splint 10 and the driven splint 11 are loosened outward. After the active splint 10 is completely loosened, the translation detection position 13 is triggered. At this time, the lifting frame 7 moves downward again. When the lifting frame 7 triggers the trigger point below the highest trigger point in the lifting detection position 14, the active splint 10 and the driven splint 11 move inward again to clamp the stacked material box. After the stacked physical boxes above the stacked material boxes except the bottom material box are lifted and fixed again, the initial steps are repeated, and the bottom material box is taken out through the lifting frame 7 again. The above steps are repeated until the stacked material boxes are used up.

[0035] 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.
