Description

Technical Field

[0001] The utility model relates to the technical field of logistics, in particular to an air blowing and rejecting system for misplaced packages. Background Art

[0002] In the logistics market, a circular conveyor line driven by a linear motor is generally connected to a "trolley" carrying a small belt conveyor. When the "trolley" moves to the designated sorting position driven by the circular main line, the drive device on the "trolley" will rotate the belt to sort and send out the items on the "trolley". In terms of mechanical form, the main conveyor line and the belt conveyor line on the "trolley" are in a cross shape, so it is called a "cross belt".

[0003] The cross-belt is the mainstream sorting and transportation equipment in the current logistics market. Its high sorting efficiency, high sorting accuracy, simple operation and convenient application make it widely used in major express logistics center outlets. The cross-belt sorting machine uses the belt surface as the load-bearing unit to sort logistics parcels. However, during the loading process, the parcels may be misplaced and stranded between the two belts due to problems such as inaccurate feeding, resulting in abnormal sorting or even misclassification. At present, the solutions to the above problems are divided into two categories: manual rejection and automatic rejection. Among them, manual rejection of misplaced parcels not only affects efficiency but also poses a great safety hazard. Among the automatic rejection methods, the air blowing method for rejecting misplaced parcels has significant advantages such as non-contact, high efficiency and simple structure.

[0004] However, although there are related devices designed for this situation on the market, the devices usually have the following problems:

[0005] The commonly used air blowing method for removing packages uses a single nozzle, which results in limited kinetic energy and makes it difficult to remove heavy packages;

[0006] Secondly, the recycling plan for misplaced packages is not yet clear, mainly because the cross-ring conveyor line moves at a high speed. If the nozzle kinetic energy is insufficient, it will also affect the recycling effect of the misplaced packages, making it impossible to recycle the misplaced packages at the designated location.

[0007] At the same time, the device occupies a large space, places a high load on the bracket, and cannot meet the actual use requirements of sites with limited space.

[0008] To this end, we propose an air blowing rejection system for misaligned packages. Utility Model Content

[0009] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides an air blowing rejection system for misaligned packages, so that packages with heavier weight can be quickly rejected through multiple nozzles of combined design.

[0010] The technical solution adopted by the utility model is as follows:

[0011] An air blowing rejection system for misaligned packages includes a mounting frame, and:

[0012] A conveyor line installation station, to which a conveyor loop line for conveying packages is connected;

[0013] A nozzle assembly is located on one side of the conveying loop, and the nozzle assembly includes three nozzles distributed in an inverted triangle, and the nozzles are vertically facing the conveying loop, and are used to blow off the misplaced packages on the conveying loop;

[0014] The nozzle at the lowest end is tilted downward, and the lower edge of the nozzle is infinitely close to the upper end surface of the conveying loop.

[0015] Furthermore, the structure of the nozzle assembly includes two nozzles 1 located in the same plane and arranged in parallel, and a nozzle 2 located below the two nozzles 1 and on the mid-vertical line.

[0016] Furthermore, the vertical height between nozzle one and nozzle two is less than the height of the offset package, and nozzle one is located above the center of gravity of the offset package.

[0017] Furthermore, the deflection angle between the nozzle 2 and the horizontal plane is between 5° and 30°, and the size of the deflection angle is inversely proportional to the vertical height between the nozzle 1 and the nozzle 2, that is, the smaller the vertical height between the nozzle 1 and the nozzle 2, the larger the deflection angle.

[0018] Furthermore, the number of the conveyor line installation stations is two and they are vertically distributed up and down, and the number of the nozzle assemblies corresponds to the conveyor loop line.

[0019] Furthermore, it also includes a recovery component, which is located on the other side of the conveying loop and opposite to the nozzle assembly. The recovery component includes an inclined plate 1 that is directly overlapped with the conveying loop and inclined downward, and an inclined plate 2 that is overlapped with the inclined plate 1 and inclined downward, and the multiple inclined plates cooperate with each other to guide the misplaced packages to the specified position.

[0020] Furthermore, a corresponding buffer mechanism is provided above the inclined plate, and the buffer mechanism is attached to the upper end surface of the inclined plate to buffer and decelerate the misaligned packages.

[0021] Furthermore, the mounting frame is provided with a protective cover which semi-surrounds the nozzle assembly to reduce noise.

[0022] Furthermore, the nozzle assembly also includes a bracket, which is composed of two longitudinal bars and two transverse bars. The longitudinal bars and the transverse bars are connected by a universal clamp to achieve longitudinal movement. Two nozzles, one is connected to the transverse bar at the upper end, and nozzle two is connected to the transverse bar at the lower end, and each nozzle is fixed to the transverse bar by a T-clamp to achieve horizontal movement.

[0023] Furthermore, a solenoid valve is provided on the nozzle.

[0024] The beneficial effects of the utility model are as follows:

[0025] The utility model has a compact and reasonable structure and is easy to operate. By designing the nozzle assembly into three inverted triangle nozzles, the misplaced packages on the conveyor loop can be quickly blown off, so that the nozzle assembly has a greater force, and the misplaced packages can be quickly blown off. It is also suitable for packages with heavier weights. At the same time, it is equipped with a recovery device, which can recover the quickly rejected packages to the specified position, thereby improving the rejection effect and having strong practicality.

[0026] At the same time, the utility model also has the following advantages:

[0027] (1) The use of three nozzles can improve the power of the airflow. The three nozzles are distributed in a triangular shape, with the two upper nozzles distributed horizontally and the lower nozzle located on the median. The lower nozzle is tilted downward, so that the high-pressure airflow is ejected from the two horizontal upper nozzles and expands in a wave-like conical path. Using this principle, the lower row of nozzles 2 and the upper row of nozzles 1 are adjusted to present a certain angle, which reduces the mutual interference between the upper and lower layers of high-pressure air during the stroke and improves the maximum thrust.

[0028] (2) The high-pressure airflow ejected from the horizontal nozzle 1 is located above the center of gravity of the package. Therefore, when the misaligned package is pushed, the side of the misaligned package facing the nozzle 1 will slightly rise. Then, the downwardly inclined nozzle 2 can provide an entry from the bottom surface of the misaligned package, thereby slightly lifting the misaligned package, which in turn reduces the friction of the misaligned package, thereby blowing the package away from the conveyor line faster. At the same time, it can also handle packages with heavier weights.

[0029] (3) In this embodiment, since the speed of removing the misaligned package is fast, the recovery component can be directly opposite to the nozzle component, so the width of the recovery component can be reduced, and the recovery of the misaligned package can be realized, thereby reducing the occupied space and reducing the load of the mounting frame. On the contrary, if the speed of removing the misaligned package is slow, a wider recovery component will be required, thereby occupying a larger space and increasing the load of the mounting frame.

[0030] (4). Nozzle 2 is extremely close to the upper end surface of the conveying loop, so that the airflow ejected from nozzle 2 can better cut into the bottom surface of the offset package. At the same time, the extremely close proximity does not mean direct contact. In this embodiment, the vertical distance between nozzle 2 and the upper end surface of the conveying loop is less than cm, which enables the ejected airflow to directly cut into the bottom surface of the offset package instead of blowing all of it directly onto the upper end surface of the conveying loop.

[0039] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0040] like Figure 1-Figure 4 As shown, the present embodiment discloses an air blowing removal system for misaligned packages, including a mounting frame 100, and a conveyor line mounting station 500 and a nozzle assembly 300 arranged on the mounting frame 100. A conveyor line 700 is installed on the conveyor line mounting station 500. The nozzle assembly 300 includes three inverted triangle-shaped nozzles, which can quickly blow off the misaligned packages 800 on the conveyor line 700. At the same time, through the special structural design of the nozzle assembly 300, the nozzle assembly 300 has a greater force, which can quickly blow off the misaligned package 800, and is also suitable for packages with heavier weight, and has strong practicality.

[0041] A conveyor line installation station 500 is connected to a conveyor line 700 for conveying packages. The conveyor line 700 is inclined because it needs to overcome centrifugal force at a bend, but is usually horizontal at a straight end. In this embodiment, the nozzle assembly 300 is located in the horizontal section of the conveyor line 700 to facilitate blowing out the misaligned package 800.

[0042] The nozzle assembly 300 is located on one side of the conveying loop 700 and includes three nozzles distributed in an inverted triangle and facing vertically toward the conveying loop 700 to blow off the misaligned packages 800 on the conveying loop 700;

[0043] In this embodiment, the number of the conveyor line installation stations 500 is two and they are vertically distributed up and down, and the number of the nozzle assemblies 300 corresponds to the conveyor loop line 700.

[0044] The structure of the nozzle assembly 300 includes two nozzles 1 302 located in the same plane and arranged in parallel, and a nozzle 2 303 located below the two nozzles 1 302 and on the mid-vertical line.

[0045] In this embodiment, the power of the airflow can be improved by using three nozzles. The three nozzles are distributed in a triangle, with the two upper nozzles distributed horizontally and the lower nozzle located on the mid-vertical line. The nozzle located at the lower end is tilted downward, so that the high-pressure airflow is ejected from the two upper horizontal nozzles 302, and will present a wave-like conical path expansion. Using this principle, the lower row of nozzles 303 and the upper row of nozzles 302 are adjusted to present a certain angle, which reduces the mutual interference between the upper and lower layers of high-pressure air during the stroke and improves the maximum thrust.

[0046] At the same time, the vertical height between nozzle one 302 and nozzle two 303 is less than the height of the offset package 800, and nozzle one 302 is located above the center of gravity of the offset package 800, and the nozzle at the lowest end is tilted downward, and the lower edge of the nozzle is infinitely close to the upper end surface of the conveying loop 700, which can facilitate the airflow ejected from nozzle two 303 to cut into the bottom surface of the offset package 800, thereby separating the offset package 800 from the conveying loop 700 and reducing friction. In this embodiment, nozzle two 303 is wirelessly close to the upper end surface of the conveying loop 700, so that the airflow ejected from nozzle two 303 can better cut into the bottom surface of the offset package 800, and wireless proximity is not direct contact. In this embodiment, the vertical distance between nozzle two 303 and the upper end surface of the conveying loop 700 is less than 2 cm, which can enable the ejected airflow to directly cut into the bottom surface of the offset package 800, rather than blowing all of it directly onto the upper end surface of the conveying loop 700.

[0047] The high-pressure airflow ejected from the horizontal nozzle 1 302 is located above the center of gravity of the package. Therefore, when the offset package 800 is pushed, the side of the offset package 800 facing the nozzle 1 302 will rise slightly, and then the downwardly inclined nozzle 2 303 can provide an entry from the bottom surface of the offset package 800, thereby slightly lifting the offset package 800, thereby reducing the friction of the offset package, thereby blowing the package away from the conveyor line faster, and also being able to handle heavier packages.

[0048] The deflection angle α between nozzle 2 303 and the horizontal plane is between 5° and 30°, and the size of the deflection angle α is inversely proportional to the vertical height between nozzle 1 302 and nozzle 2 303, that is, the smaller the vertical height between nozzle 1 302 and nozzle 2 303, the larger the deflection angle α. If the deflection angle α is greater than 30°, the airflow blown into the bottom of the dislocated package 800 will be.

[0049] The smaller the vertical height of the nozzle 1 302 and the nozzle 2 303 is, the greater the interference between the high-pressure airflows ejected from the two nozzles is. Therefore, the interference is avoided by adjusting the angle of the nozzle 2 303, and vice versa.

[0050] In this embodiment, Figure 1 As shown, it also includes a recovery component 400, which is located on the other side of the conveying loop 700 and opposite to the nozzle assembly 300. The recovery component 400 includes an inclined plate 1 401 that is directly overlapped with the conveying loop 700 and tilted downward, and an inclined plate 2 402 that is overlapped with the inclined plate 1 401 and tilted downward, and the multiple inclined plates cooperate with each other to guide the misaligned package 800 to a specified position.

[0051] In this embodiment, since the removal speed of the misaligned package 800 is fast, the width of the recovery component 400 can be reduced, and the recovery of the misaligned package 800 can be achieved. On the contrary, if the removal speed of the misaligned package 800 is slow, a recovery component 400 with a larger width will be required, thereby occupying a larger space and increasing the load of the mounting frame 100.

[0052] A corresponding buffer mechanism 600 is provided above the inclined plate. The buffer mechanism 600 is attached to the upper end surface of the inclined plate to buffer and slow down the misaligned package 800. Also, since the removal speed of the misaligned package 800 is too fast, it needs to be buffered to prevent the package from being damaged.

[0053] Since there are three nozzles in the nozzle assembly 300 and the airflow generated is large, which will produce a lot of noise, a protective cover 200 that half surrounds the nozzle assembly 300 is also provided on the mounting frame 100 to reduce the noise.

[0054] The nozzle assembly 300 also includes a bracket 301, which is composed of two longitudinal bars and two transverse bars. The longitudinal bars and the transverse bars are connected by a universal clamp 305 to achieve longitudinal movement. The two nozzles 1 302 are connected to the transverse bar at the upper end, and the nozzle 2 303 is connected to the transverse bar at the lower end. Each nozzle is fixed to the transverse bar by a T-clamp 304 to achieve horizontal movement, so that the nozzle assembly 300 can adapt to more different packages.

[0055] In this embodiment, Figure 2-Figure 4As shown, a solenoid valve 306 is provided on the nozzle, and the start of the nozzle is controlled by electronic control. In actual use, a grayscale meter is usually used to detect whether the package is in an abnormal position. After determining the misplaced package 800, the grayscale meter will feed back the position information of the misplaced package 800 to the solenoid valve 306. After receiving the signal, the solenoid valve 306 starts the nozzle to blow the misplaced package 800 off.
