In order to prevent collision during the running process of the plurality of the sub-sowing vehicles 2, the plurality of sub-sowing vehicles 2 run on the first track 52 in the same direction, namely, the sub-sowing vehicle 2 carrying the articles runs along one side of the first track 52, and the sub-sowing vehicle 2 returned after the unpacking runs along the other side of the first track 52. The packet supply table 1 and the storage rack 51 are arranged side by side in the width direction of the main wall body 5, the packet supply table 1 is arranged at the front side of the main wall body 5 along the depth direction, and a buffer storage station is arranged at one side close to the distribution vehicle 2.

The article is input by the line mouth, generally acquires bar code information on the article through the handheld terminal by the manual work, can also realize scanning the code through the five faces on the conveying line automatically, discerns the position that the article needs the branch to broadcast. The inside of the distributing wall is provided with a plurality of distributing vehicles 2 which can move along the track 52 by themselves, the distributing vehicles 2 for packing will be parked at the packing position, under the condition that the distributing vehicles 2 are in butt joint with the packing platform 1, the packing platform 1 provides the objects to the distributing vehicles 2, then the distributing vehicles 2 automatically transport the objects to the destination, and the objects are unloaded into the containers 6 corresponding to the target grid at one side of the destination. Then, the multicast vehicle 2 returns to the package loading position to continue receiving packages, and a plurality of multicast vehicles 2 circularly run.

The distribution truck 2 can receive and unload the articles through the circulating rotation of the belt, when receiving the articles, the belt is required to rotate to match the articles to be transmitted to the distribution truck 2 by the packet supply platform 1, and after the articles are received, the belt is required to stop rotating to stably bear the articles. That is, the cart 2 needs to acquire information about whether the article is being transferred to the cart 2 or whether the article has been completely transferred to the cart 2, thereby controlling the belt rotation of the cart 2.

In the related art, a mode of realizing the package detection of the articles is provided, the detection components are all arranged on the distribution truck 2, and even if the setting density of the detection components is increased, a good identification effect can not be achieved on ultrathin articles, and the cost is high. Thus, the present application provides an improved automatic distribution device.

In some embodiments, as shown in fig. 1 to 3, the present disclosure provides an automatic distribution device, including:

the bag supply table 1 comprises a first conveying member 11 configured to convey articles in a first direction x;

a distribution cart 2 including a second conveying member 21 configured to receive the articles supplied from the first conveying member 11 at the packing position; and

a first detecting unit 3 fixed in position with respect to the bag table 1 and configured to detect whether or not there is an article in the interface region between the first conveying member 11 and the second conveying member 21; the first detection assembly 3 comprises a plurality of vertical sensors arranged in a row along a second direction y, which is angled in a horizontal plane with respect to the first direction x;

Wherein the vertical sensor is provided at least one position above and below the plane in which the conveying surface of the first conveying member 11 is located, and the vertical sensor is configured such that its detection line is angled with respect to the first direction x in the vertical plane.

In this embodiment, the packing station 1 comprises a first conveying member 11 extending in the first direction x, and the packing station 1 may be provided with a buffer station at the end that interfaces with the trolley 2. The buggy 2 comprises a second transport element 21 which interfaces with the feed table 1 when the buggy 2 is in the up-packing position, in which case the second transport element 21 extends in the first direction x, and the items provided by the feed table 1 to the buggy 2 may be goods in the order, optionally packages. For example, the first conveying member 11 or the second conveying member 21 may be a belt, a chain, a roller conveying member, or the like.

The first detecting component 3 is fixed relative to the position of the package supplying table 1, and cannot move along with the distributing vehicle 2, and is different from the scheme that all detecting components are arranged on the distributing vehicle 2, for example, the first detecting component 3 can be arranged at the positions of the package supplying table 1, the main wall 5 and the like or arranged through a bracket arranged on the ground. The interface region of the first conveying member 11 and the second conveying member 21 includes: the first conveying member 11 is near one end of the cart 2, between the first conveying member 11 and the second conveying member 21, and the second conveying member 21 is near one end of the bag-feeding table 1.

The first detection assembly 3 comprises a plurality of vertical sensors which are arranged at intervals along the second direction y, when articles pass through the butt joint area, the detection state of the vertical sensors is changed, and whether the articles pass through or not can be judged by judging the output signals of the vertical sensors. Optionally, the first detection assembly 3 comprises a plurality of vertical sensors arranged next to each other along the second direction y, the detection lines of the plurality of vertical sensors also being arranged at intervals.

The meaning of the second direction y being angled in the horizontal plane with respect to the first direction x is: the projection intersection of the second direction y and the first direction x in the horizontal plane is angled, but the two directions themselves do not have to lie in one plane. For example, the second direction y may be perpendicular to the first direction x, where the first direction x is consistent with the depth direction of the main wall 5, the second direction y is consistent with the width direction of the main wall 5, and the plurality of vertical sensors are arranged along the width direction of the first conveying member 11, so that the difficulty in arranging the vertical sensors can be reduced, and since each vertical sensor is consistent with the distance between the first direction x and the end of the first conveying member 11, the opening timing of the second conveying member 21 can be consistent regardless of the package being supplied from any position of the first conveying member 11 along the width direction.

Alternatively, the second direction y may be at another angle to the first direction x, i.e., the arrangement direction of the plurality of vertical sensors is inclined with respect to the width direction of the first conveying member 11, or the bag supplying direction of the bag supplying table 1 is inclined with respect to the depth direction of the main wall 5.

The plurality of vertical sensors may be disposed at uniform intervals along the second direction y, and the set density may be set according to the width of the article to be wrapped.

The meaning of the vertical sensor is that the detection line is located in a plane perpendicular to the second direction y, which detection line may extend in a vertical direction or in an oblique direction. The sense that the sense line of the vertical sensor is angled in the vertical plane with respect to the first direction x is: the detection line of the vertical sensor intersects the projection of the first direction x in a vertical plane at an angle, but the detection line and the first direction x do not necessarily lie in one plane.

In this embodiment, a plurality of vertical sensors are disposed in the docking area of the first conveying member 11 and the second conveying member 21 along the second direction y, and even if an ultrathin article passes through the docking area, the ultrathin article, such as a letter or a paper, can be detected even if the detection line of the vertical sensor is angled to the first direction x in the vertical plane, so that the coverage items of the package detection can be increased, the package detection can be stably and effectively performed, and a basis is provided for determining the start timing of the second conveying member 21, thereby improving the operation efficiency and stability of the automatic distribution device.

Moreover, as the first detection assemblies 3 are fixedly arranged relative to the packet supply table 1, only one set of first detection assemblies 3 are needed, and the first detection assemblies 3 are not needed to be additionally arranged on each sub-sowing vehicle 2, the number of the sensors can be greatly reduced, the design difficulty of the second conveying components 21 in the sub-sowing vehicle 2 is reduced, and the cost of the automatic sub-sowing device can be reduced.

In some embodiments, the vertical sensor is configured such that its detection line passes through the gap between the first conveying member 11 and the second conveying member 21.

This embodiment can determine that the article has completely reached the end of the first conveying member 11 when the detection signal of the vertical sensor changes, so as to accurately determine the timing of opening the second conveying member 21. In addition, when the vertical sensor comprises two parts, the part positioned below can be more conveniently installed for detection, so that the vertical sensor is convenient to install no matter only comprises one part or two parts, and the adaptability to different sensor types is improved.

In some embodiments, as shown in fig. 4, the first detection assembly 3 is mounted to the bag supply stand 1. Alternatively, the first detecting assembly 3 may be mounted on the main wall 5 or a stand may be provided on the ground.

Because the package supplying table 1 is closest to the butt joint area, the first detection assembly 3 is arranged on the package supplying table 1, the setting difficulty of the mounting bracket can be reduced, and the mounting accuracy can be improved, so that the accuracy of package loading detection is improved. In addition, when the position of the first detection component 3 needs to be moved or adjusted, the first detection component 3 can move along with the packet supply table 1, so that the flexibility of adjusting the automatic distribution device according to the working requirement is improved.

In some embodiments, each vertical sensor includes a first portion 31 and a second portion 32 facing each other, the first portion 31 being above the conveying surface of the first conveying member 11, the second portion 32 being below the conveying surface of the first conveying member 11, and a detection line being formed between the first portion 31 and the second portion 32. The second portion 32 is integrally located below the conveying surface of the first conveying member 11, so as not to affect the conveying of the articles, and according to the setting requirement, the upper surface of the second portion 32 may be lower than the conveying surface of the first conveying member 11 or flush with the conveying surface of the first conveying member 11.

In this embodiment, for ease of detection, the detection line T between the first portion 31 and the second portion 32 may pass through the gap between the first conveying member 11 and the second conveying member 21, so that an article can be detected when the article passes through, and the detection line between the first portion 31 and the second portion 32 is blocked when the article passes through the docking area, and no signal is output from the vertical sensor; when no article passes through the docking area, a detection line is arranged between the first part 31 and the second part 32, and the vertical sensor outputs a signal.

For example, the first portion 31 and the second portion 32 may be one transmitting end and the other receiving end; or one may be both the transmitting and receiving ends and the other may be the reflecting end. The detection line may extend from top to bottom, or from bottom to top.

As shown in fig. 3, the first portion 31 and/or the second portion 32 may be provided with a cover 133 for protection. Fig. 4 is a schematic view of removing the cover 133 to expose the first portion 31.

According to the embodiment, the vertical sensor is arranged into two parts, and object detection can be realized through correlation, specular reflection and other principles, so that the detection precision of objects when passing can be improved, and the accuracy of detecting the objects when packing is improved.

In some embodiments, as shown in fig. 4, a plurality of first portions 31 form a channel with the first conveying member 11 for passage of articles. The upper surface of the first conveying member 11 is a conveying surface, and the distance between the first portion 31 and the upper surface of the first conveying member 11 requires the passage of the articles to be packed having the greatest height. This structure allows the first detecting member 3 to be provided without affecting normal conveyance of the article.

In some embodiments, the distance between the first portion 31 and the first conveying member 11 is greater than the distance between the second portion 32 and the first conveying member 11 in the height direction z. Wherein the height direction z is perpendicular to the first direction x and the second direction y.

In this embodiment, the first portion 31 and the first conveying member 11 are set to have a larger distance, which allows articles with a larger height to pass through, so that the types of the articles to be packed can be increased, and on the basis, the second portion 32 and the first conveying member 11 are set to have a smaller distance, which shortens the distance between the first portion 31 and the second portion 32, so as to reduce the detection distance and improve the accuracy and stability of the detection of the vertical sensor.

In some embodiments, as shown in fig. 4 and 5, the bag supplying table 1 further includes two first side plates 12 of the first bracket 13 and the second bracket 14, the first side plates 12 are respectively located at two sides of the first conveying member 11 along the second direction y, a plurality of first portions 31 are mounted on the two first side plates 12 through the first bracket 13, and a plurality of second portions 32 are mounted on the two first side plates 12 through the second bracket 14.

As shown in fig. 4, the first bracket 13 may include two first fixing brackets 131 and a second fixing bracket 132, wherein first ends of the two first fixing brackets 131 are respectively connected to top positions of the two first side plates 12, second ends of the two first fixing brackets extend toward the upper region, the second fixing bracket 132 is connected between the two first fixing brackets 131, and the plurality of first portions 31 are mounted on the second fixing bracket 132 at intervals along the second direction y. For example, the first and second holders 131 and 132 may be provided in a rod-shaped, plate-shaped structure, and the cross section of the rod-shaped structure may be circular or L-shaped. In order to mount the first portion 31 in place in the first direction x, the first fixing bracket 131 may be disposed vertically or obliquely.

As shown in fig. 5, the second bracket 14 may include two third fixing frames 141, and first ends of the two third fixing frames 141 are respectively connected to middle lower portions of the two first side plates 12, and second ends of the two third fixing frames extend toward the lower region. If the second portion 32 is a reflective element and a plurality of reflective elements are independently disposed, the second support 14 may further include a fourth fixing frame connected between the two third fixing frames 141, and the plurality of reflective elements are installed at intervals on the fourth fixing frame. If a plurality of reflectors are arranged as integral strip reflectors, two ends of the strip reflectors can be directly connected between the two third fixing frames 141, so that the arrangement of the fixing frames can be simplified, and the strip reflectors can increase the reflecting area, thereby improving the detection accuracy.

This embodiment enables the first portion 31 and the second portion 32 to be flexibly and reliably mounted on the bag-feeding table 1, and by mounting the first side plates 12 on both sides, the mounting stability can be improved without affecting the conveyance of the articles.

In some embodiments, the distance of the first portion 31 from the end of the first conveying member 11 is greater than the distance of the second portion 32 from the end of the first conveying member 11 in the first direction x, such that the detection line is tilted through the gap between the first conveying member 11 and the second conveying member 21. Alternatively, the first portion 31 and the second portion 32 may be aligned up and down so that the detection line passes vertically through the gap.

Specifically, the extension length of the first fixing frame 131 in the first direction x is greater than that of the third fixing frame 141.

In this embodiment, considering that the space above the first conveying member 11 is relatively abundant and the space below is relatively compact, the arrangement mode can fully consider the space characteristics of the tail end of the bag supplying table 1, and the first portion 31 and the second portion 32 are staggered along the first direction x, so that the detection line is inclined to pass through the gap between the first conveying member 11 and the second conveying member 21, the detection line is prevented from being blocked, and the reliability of the article detection is improved.

In some embodiments, as shown in fig. 4 and 5, the first portion 31 includes a mirror sensor and the second portion 32 includes a reflector. As shown in fig. 6 and 7, the mirror counter sensor serves as both a transmitting end and a receiving end, and the detection lines T emitted from the mirror counter sensor reach the reflecting member and are reflected by the reflecting member to be received by the mirror counter sensor, so that each vertical sensor forms two detection lines T.

Specifically, a first bracket 13 is disposed at the end of the buffer station of the packet supply table 1, and a plurality of mirror-image sensors are disposed on a second fixing frame 132 above the first conveying member 11 at equal intervals along the second direction y, and a reflecting member is fixed below the first conveying member 11 by a second bracket 14 for detecting the mirror-image sensors. Thus, when the object blocks the detection line, the signal changes, the object passes through the detection position, and when the signal is recovered, the object is judged to completely pass through the detection position.

The vertical sensor of the embodiment has a more stable detection effect and is lower in price, and the overall cost of the automatic distribution device can be reduced. Moreover, the plurality of reflecting pieces can be designed into continuous strip-shaped reflecting pieces, such as reflecting plates, so that the reflecting area can be increased, the detection accuracy is further improved, and the installation difficulty can be reduced.

Alternatively, the vertical sensor may be a photoelectric correlation sensor, where the first portion 31 is a transmitting end and the second portion 32 is a receiving end. Optionally, the vertical sensor may be a diffuse reflection sensor, and the transmitting end and the receiving end are integrated together, so that diffuse reflection is realized by means of the surface of the article when the article passes through, and the reflecting end is not required to be arranged. The form of the mounting bracket, the mounting location and the type of vertical sensor are all optional.

In some embodiments, the plurality of vertical sensors covers the entire width of the first conveying member 11, and the spacing of adjacent two vertical sensors in the second direction y does not exceed the minimum width of the article to be provided.

For example, the spacing between adjacent vertical sensors may be around 2cm, since, in view of the objects currently to be distributed, substantially more than 2cm wide, substantially no objects below 2cm wide are present, i.e. no missed objects passing only between adjacent vertical sensors are present.

This embodiment allows the plurality of vertical sensors to cover the entire width of the first conveying member 11, so that the requirement for placing the articles on the first conveying member 11 in the second direction y can be reduced, and the bag feeding efficiency can be improved. Moreover, the distance between two adjacent vertical sensors along the second direction y does not exceed the minimum width of the article to be provided, so that the number of the sensors can be reduced and the cost can be reduced under the condition of preventing the article from being detected in a missing manner.

In some embodiments, the jukebox 2 is configured to enable contactless communication with the vertical sensor at the package location. When the signal of the vertical sensor changes, information needs to be transmitted to the distribution vehicle 2 so that the distribution vehicle 2 can perform corresponding actions.

Specifically, a first magnetic ring is arranged at the tail end of a buffer station of the packet supply table 1, a second magnetic ring is arranged at the end of the sub-sowing vehicle 2, when the sub-sowing vehicle 2 stops at the packet loading position, the first magnetic ring corresponds to the second magnetic ring, and when the signal of the vertical sensor changes, the signal can be transmitted to the sub-sowing vehicle 2. The first magnetic ring generates current, the second magnetic ring is internally provided with a magnetic induction switch, and the magnetic induction switch can detect the current when the current changes, so that signals can be stably transmitted. Alternatively, the contactless communication may be infrared detection or wifi communication, as long as a signal transmission manner can be achieved.

By adopting the contactless communication, the signal receiving part on the distribution truck 2 can retract inwards relative to the second conveying part 21 in the design, the collision can be prevented during the operation of the distribution truck 2, and the reliability of the distribution process of the articles can be improved.

In some embodiments, as shown in fig. 8, the automated distribution device further comprises a second detection assembly 4 configured to detect whether the first conveying member 11 and the second conveying member 21 have an article in the interface region; the second detecting assembly 4 includes a lateral sensor provided above the second conveying member 21 on at least one side in the own width direction, and the lateral sensor is configured such that its detection line is angled with respect to the first direction x in a horizontal plane. In the case where the first conveying member 11 and the second conveying member 21 are close in width and the conveying surfaces are flush, the lateral sensor is also located above the first conveying member 11 on at least one side in the own width direction.

The second detecting assembly 4 may be disposed in a docking area of the first conveying member 11 and the second conveying member 21, for example, the second detecting assembly 4 may be mounted on the position of the seed-sowing vehicle 2, the packet-supplying table 1, the main wall 5, or the like, or may be mounted by a bracket disposed on the ground.

For example, the second detecting component 4 is a photoelectric correlation sensor or a mirror reflection sensor, and the second detecting component 4 is arranged at two sides of the second conveying component 21; the second detecting element 4 is a diffuse reflection sensor, and the second detecting element 4 is provided on one side of the second conveying member 21.

The meaning of "transverse" includes perpendicular to the first direction x or at other oblique angles in the horizontal plane. The sense that the detection line of the lateral sensor is angled in the horizontal plane with respect to the first direction x is: the detection line of the lateral sensor intersects the projection of the first direction x in a horizontal plane at an angle, but the detection line is not necessarily in a plane with the first direction x.

This embodiment provides a lateral sensor above the second conveying member 21 in the docking area, which may form a detection line that is angled in the horizontal plane with respect to the first direction x, and which is parallel to the conveying plane of the second conveying member 21; furthermore, a vertical sensor is arranged between the packet supply table 1 and the distribution vehicle 2 to form a vertical or inclined detection surface. For articles of narrower width, even if not detected by the vertical sensor, it can be detected by the lateral sensor; for ultra-thin articles, even if not detected by the lateral sensor, it is detected by the vertical sensor. Therefore, the first detecting component 3 and the second detecting component 4 are complementary, and the package detection can be realized more accurately.

The cart 2 is generally provided with correlation sensors at both ends of the second conveying member 21 to form a detection plane for detecting the articles, and is generally provided with a small number for cost consideration, thus forming an incomplete detection plane. Therefore, a certain detection blind area exists above the second conveying part 21, detection of ultrathin articles is invalid, in addition, for some articles with different heights, transverse spaced detection light rays can not detect the articles in the initial stage or the final stage of packing, and the vertical sensor is arranged to enable the vertical sensor to cross the detection line of the transverse sensor, so that the article detection range can be covered to a greater extent, and the accuracy of article packing detection is improved.

It should be noted that, the detection lines in the drawings are merely to illustrate the correspondence of the sensors, and the detection lines may be visible or invisible.

In some embodiments, the lateral sensor includes opposite third and fourth portions 41, 42, the third and fourth portions 41, 42 being located on opposite sides of the second conveying member 21, respectively. For example, the third portion 41 and the fourth portion 42 may be disposed directly opposite in the width direction of the second conveying member 21.

For example, the third portion 41 comprises a mirror sensor with an emitting end and a receiving end, and the fourth portion 42 comprises a reflector; alternatively, the transverse sensor may be a photoelectric correlation sensor, where the third portion 41 is a transmitting end and the fourth portion 42 is a receiving end.

According to the embodiment, the transverse sensor is arranged into two parts, and object detection can be realized through correlation, specular reflection and other principles, so that the detection precision of objects when passing can be improved, and the accuracy of detecting the objects when packing can be improved.

In order to prevent missing articles, the distance of the bottommost transverse sensor from the second conveying means 21 may be around 1cm, since, in view of the articles to be dispensed at present, the thickness is substantially above 1cm, and no articles having a width below 1cm are substantially present, i.e. so arranged that a large part of the articles can be identified by the transverse sensor.

In a specific embodiment, the distance between adjacent vertical sensors is 2cm and the distance between the bottommost lateral sensor and the second conveying means 21 is 1cm, since, from the point of view of the articles currently to be distributed, substantially articles with a thickness above 1cm or a width above 2cm are rarely present, having a thickness below 1cm and a width below 2 cm. That is, most of the articles have a certain thickness or a certain width, and few thin and narrow articles exist, so that any article cannot escape from the light detection net formed by the vertical detection line and the horizontal detection line, and therefore, the light detection net can cover detection of most of the articles and reduce the setting cost of the sensor.

In some embodiments, the automated distribution device further comprises a controller configured to cause the second conveying member 21 to be opened in case at least one of the first detection assembly 3 and the second detection assembly 4 detects an item.

In the working process, the articles are conveyed to the buffer station at the tail end by the packet supply table 1, the first conveying part 11 conveys the articles to the sub-sowing vehicle 2, when the sub-sowing vehicle 2 is at the packet loading position, the first conveying part 11 rotates to convey the articles to move to the sub-sowing vehicle 2, in the process, the articles are detected through the vertical sensor and the transverse sensor, any sensor generates signals, the signals are sent to the sub-sowing vehicle 2, the articles are informed to start entering the sub-sowing vehicle 2, and the sub-sowing vehicle 2 receiving the signals starts to start the second conveying part 21 to receive the articles. The first detection component 3 and the second detection component 4 are complementary to each other to detect the package more accurately, so that the efficiency and smoothness of the automatic distribution process are improved.

In some embodiments, the second detection assembly 4 is mounted on the seed vehicle 2. Specifically, the second detection assembly 4 is mounted at an end region of the seed vehicle.

The second detection component 4 in this embodiment can realize packet loading detection, and can realize packet unloading detection when the multicast vehicle 2 unloads the object to the target grid, so that the packet loading and unloading processes realize multiplexing of the sensors, and the number of the sensors can be reduced.

In order to enable the packet delivery vehicle 2 to perform packet delivery more flexibly, the second detection assemblies 4 are disposed at both ends of the second conveying member 21, and the second detection assemblies 4 at either end can be used for packet loading detection or packet unloading detection.

Optionally, the second detection assembly 4 is fixed relative to the position of the packet supply platform 1, and when the packet unloading detection is not required to be set, only one set of second detection assembly 4 is required to be set, the second detection assemblies 4 are not required to be respectively installed on the plurality of the sub-sowing vehicles 2, the setting quantity of sensors can be reduced, and the design difficulty of the sub-sowing vehicles 2 is reduced.

In some embodiments, as shown in fig. 8, the seed-sowing vehicle 2 includes two second side plates 22, the two second side plates 22 are respectively located at two sides of the second conveying member 21 along the second direction y, and the third portion 41 and the fourth portion 42 are respectively mounted to the two second side plates 22. For example, may be mounted to an inner sidewall or end of the second side plate 22.

In this embodiment, the transverse sensor is mounted on the second side plate 22 of the seed sowing vehicle 2, and the transverse sensor is just positioned on two sides of the second conveying component 21 to form correlation, so that the mounting is simple, and the conveying of the articles is not affected.

In some embodiments, as shown in fig. 8, both ends of the second conveying member 21 along the first direction x are provided with second detecting assemblies 4, and the second detecting assemblies 4 are located inside the end edges of the second conveying member 21 along the first direction x; the automatic distribution device further comprises a controller configured to issue an article overlength reminder if the second detection assemblies 4 at both ends detect an article.

For this arrangement, the detection line of the transverse sensor may be slightly offset with respect to the detection plane of the vertical sensor in the direction of the first direction x toward the seed-sorting vehicle 2, without affecting the package detection of the articles.

This embodiment can be great in article length on the second conveying part 21, when surpassing the distance between two sections second detection subassembly 4, the controller sends article overlength and reminds to carry out manual handling, in order to avoid article process to bump in the in-process that the seed-metering car 2 was operated, thereby improves the security of automatic seed-metering process.

In some embodiments, the automated distribution device further comprises a controller, the second detection assembly 4 serving as a wrap detection, the controller being configured to deactivate the second conveying member 21 in case no item is detected by both the first detection assembly 3 and the second detection assembly 4.

In this embodiment, when the first detecting unit 3 and the second detecting unit 4 cannot detect the article after the article leaves the first conveying unit 11, it is determined that the article has been completely conveyed to the distribution truck 2, and the second conveying unit 21 stops running to complete the wrapping, so that the article is still loaded on the distribution truck 2.

In some embodiments, the automatic distribution device further comprises a controller, the second detection assembly 4 is used as a packet-unloading detection, and the controller is configured to stop the second conveying member 21 when the second conveying member 21 runs for a preset number of times after the second conveying member 21 is opened for packet unloading, or when the second detection assembly 4 detects an article first and then detects no article.

Specifically, when the cart 2 unpacks the packet to the target bin, the second detection assembly 4 may detect that the article starts to leave the second conveying member 21 if the article is detected first, and subsequently, if the article is not detected, the article has left the second conveying member 21. In order to prevent that no ultrathin piece is detected by the transverse sensor, the second conveying member 21 is made to run for a preset number of turns, for example, for a little less than half turn, a half turn, 1 turn or more than 1 turn, from the moment of opening the second conveying member 21 for unpacking, at which time the article is considered to have left the cart 2.

By adopting the dual judging mechanism, the embodiment can meet one condition, and can judge whether the package unloading is finished or not more accurately for various articles, particularly ultrathin articles, so as to ensure that the package unloading of the distribution truck 2 is finished when returning.

In some embodiments, as shown in fig. 8, the second detection assembly 4 comprises at least two lateral sensors, at least part of which are spaced apart along the height direction z; and/or at least some of the lateral sensors are spaced apart along the first direction x.

For example, the second detecting member 4 at the same end includes two lateral sensors arranged at intervals in the height direction z and/or arranged at intervals in the first direction x.

For example, two lateral sensors are arranged at an interval of about 2cm from top to bottom, and the detection height of the lateral sensor located below is about 1 cm.

In this embodiment, at least part of the transverse sensors in the same second detecting assembly 4 are arranged at intervals along the height direction z and/or the first direction x, and when one transverse sensor does not detect, the transverse sensor can detect the abnormal part through the other transverse sensor, so that the abnormal part can be detected more accurately, and the coverage degree of the abnormal part on different shaped objects can be further improved.
