Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics transmission, in particular to a positioning conveying device. BACKGROUND

[0002] The express single sending sorting technology mainly includes a single separation module, a positioning conveying module, a scanning and identifying module and a directional sorting module. The positioning conveying module mainly adopts an inclined roller or a module belt to position and convey the express.

[0003] In the prior art, the positioning conveying module has the technical problem of poor working reliability. For example, when the module belt is used to convey the express, the ball structure of the module belt is easy to be stuck in the debris generated by the unthreading of the woven bag type package, which causes the ball or the jacking structure to be stuck, and thus affects the working stability of the centering or edge positioning of the module belt. In the structure of the inclined roller, the diameter of the roller is large, and the uneven surface of the roller leads to uneven bottom, so that the inclined roller causes the express to be jolted during conveying, increasing the probability of damage to the express. SUMMARY

[0004] The present application provides a positioning conveying device, which aims to solve the technical problem of poor working reliability of the positioning conveying module in the prior art.

[0013] Optionally, one side of the first belt machine is provided with at least two second belt machines, and the at least two second belt machines are sequentially and spaced apart along the first conveying direction.

[0014] Optionally, the first belt machine comprises a first belt, and the second belt machine comprises a second belt; the width of the first belt is greater than the width of the second belt.

[0015] Optionally, the conveying surface defined by the first belt is coplanar with the conveying surface defined by the second belt.

[0016] Optionally, the conveying distance of the first belt is greater than the conveying distance of the second belt.

[0017] Optionally, the frame has a goods input end, the first input end of the first belt machine is connected with the goods input end, and the second input end of the second belt machine is connected with the goods input end.

Since the first conveying direction and the second conveying direction are cross arranged, and the output end of the second belt machine abuts at least one side of the first belt machine, when the express delivery is delivered into the positioning conveying device, if the express delivery is delivered on the second belt machine, the second belt machine can convey the express delivery along the second conveying direction to the first belt machine, so that the express delivery can be conveyed to the side or the center. Compared with the positioning conveying module in the prior art, the belt machine is stable in conveying, has few interfaces, and has a smooth surface, thereby increasing the reliability of the positioning conveying. In the technical scheme of the application, on the one hand, compared with the positioning conveying device using an inclined roller, the belt machine will not cause the express delivery to be jolted and avoid the express delivery to be clamped, thereby greatly reducing the probability of the express delivery being damaged; on the other hand, compared with the positioning conveying device using a module belt, since the belt machine moves the belt by relying on the rollers arranged oppositely, the rollers will not be clamped by sundries, and the module belt is more stable in operation.

Thus, the present application is not intended to be limited by the

[0027] An embodiment of the present application provides a positioning conveying device. Details are described below.

[0028] Referring to Figures 1 to 4 illustrated, Figure 1 is a first embodiment schematic view of the positioning conveying device provided by the present application; Figure 2 is a second embodiment schematic view of the positioning conveying device provided by the present application; Figure 3 is a scene schematic view of express movement of the positioning conveying device provided by the present application; Figure 4 is a schematic view of express movement analysis of the positioning conveying device provided by the present application.

[0029] An embodiment of the present application provides a positioning conveying device, comprising a frame 100; a first belt conveyor 200 connected with the frame 100, the first belt conveyor 200 having a first transmission direction; and a second belt conveyor 300 connected with the frame 100, the second belt conveyor 300 having a second transmission direction, and an output end of the second belt conveyor 300 abutting at least one side of the first belt conveyor 200; the first transmission direction and the second transmission direction are cross arranged.

[0030] In combination with Figure 1 and Figure 2As shown, the positioning conveying device comprises a frame 100, a first belt conveyor 200 and a second belt conveyor 300. The first belt conveyor 200 and the second belt conveyor 300 are connected with the frame 100; the first belt conveyor 200 conveys the parcels along a first conveying direction D1; the second belt conveyor 300 conveys the parcels along a second conveying direction D2. Since the first conveying direction D1 and the second conveying direction D2 are arranged in a cross manner, and the output end of the second belt conveyor 300 abuts against at least one side of the first belt conveyor 200, when the parcels are delivered into the positioning conveying device, if the parcels are delivered on the second belt conveyor 300, the second belt conveyor 300 can positionally convey the parcels along the second conveying direction D2 to the first belt conveyor 200, so that the edge or center transmission of the parcels can be realized.

[0031] Compared with the positioning transmission module of the prior art, the belt conveyor is stable in transportation, has few interfaces, and has a smooth surface, thereby increasing the reliability of positioning transmission. On one hand, compared with the positioning conveying device adopting an inclined roller, the belt conveyor of the technical scheme of the embodiment of the present application does not cause the parcels to be jolted and avoids clamping the parcels, thereby greatly reducing the probability of damage to the parcels; on the other hand, compared with the positioning conveying device adopting a module belt, since the belt conveyor drives the belt to move by means of the rollers arranged in a relative manner, the rollers of the belt conveyor cannot be stuck by sundries, so that the technical scheme of the embodiment of the present application has higher stability in operation than the module belt.

[0032] The following is a working process that can be realized by the positioning conveying device proposed in the embodiment:

[0033] After a plurality of parcels are separated into single parcels by the single-piece separation module, the single parcels are randomly delivered into the positioning conveying device. When the parcels are randomly delivered into the positioning conveying device, there are three cases for the initial delivery position of the parcels.

[0034] The first case of parcel delivery: the parcels are randomly delivered on the first belt conveyor 200, and the first belt conveyor 200 conveys the parcels to the scanning and identifying module and / or the directional sorting module along the first transmission direction;

[0035] The second case of parcel delivery: the parcels are randomly delivered on the second belt conveyor 300, and the second belt conveyor 300 drives the parcels to move to the first belt conveyor 200 along the second transmission direction, so that the parcels can be positionally conveyed to the first belt conveyor 200, and the first belt conveyor 200 conveys the parcels to the scanning and identifying module and / or the directional sorting module along the first transmission direction;

[0036] The third type of parcel delivery scenario: When the parcel is delivered, part of it is located on the first conveyor belt 200 and the other part is located on the second conveyor belt 300. While the first conveyor belt 200 is conveying the parcel along the first transmission direction, the second conveyor belt 300 provides the parcel with a speed along the second transmission direction, so that the parcel can move onto the first conveyor belt 200. The first conveyor belt 200 then conveys the parcel along the first transmission direction to the scanning and identification module and / or the orientation sorting module.

[0037] Specifically, refer to Figure 3 and Figure 4 As shown, in both the second and third delivery scenarios, the package always undergoes a transition from the second conveyor belt 300 to the first conveyor belt 200. During this transition, the first conveyor belt 200 provides the package with a first speed V1 in the first conveying direction D1, and the second conveyor belt 300 provides the package with a second speed V2 in the second conveying direction D2. Therefore, when the package transitions from the second conveyor belt 300 to the first conveyor belt 200, it has a resultant speed V. 合 The second velocity V2 can be decomposed into a velocity V parallel to the first conveying direction D1. 2x and the velocity V perpendicular to the first conveying direction D1 2y The express package has a speed V perpendicular to the first conveying direction D1. 2y It can be positioned and moved to the first conveyor belt 200; and the express item has a speed V parallel to the first conveying direction D1. 2x While being positioned and moved to the first conveyor belt 200, it can move along the first conveying direction D1 until all the packages are on the first conveyor belt 200.

[0038] It should be noted that the frame 100 has mounting positions for the first conveyor belt 200 and the second conveyor belt 300. For example, the frame 100 has a first mounting hole extending along a first conveying direction D1 and a second mounting hole extending along a second conveying direction D2. The first conveyor belt 200 is located in the first mounting hole, and the second conveyor belt 300 is located in the second mounting hole. Since the first conveyor belt 200 and the second conveyor belt 300 are intersecting, the output end of the second conveyor belt 300 cannot be completely seamlessly fitted with the first conveyor belt 200. Therefore, at the junction of the first conveyor belt 200 and the second conveyor belt 300, the frame 100 has a panel to fill the gap between the first conveyor belt 200 and the second conveyor belt 300. This panel connects the first conveyor belt 200 and the second conveyor belt 300.

[0039] It should be noted that the first belt conveyor 200 and the second belt conveyor 300 each include a belt, a driving roller and a transmission roller driving the belt to move, and a driving mechanism driving the driving roller to rotate. The driving mechanism is a device capable of realizing rotary motion, such as a direct-drive motor, a common motor cooperating with a gear reduction device, or a common motor cooperating with a worm and gear device, etc. The driving mechanism is generally connected with the frame 100 and located on the side of the belt facing the ground.

[0040] Further, it should be noted that the output end of the second belt conveyor 300, i.e., the end from which the express delivery article leaves the second belt conveyor 300. The first belt conveyor 200 has a first side and a second side arranged oppositely. The direction in which the first side points to the second side is the width direction of the first belt conveyor 200. The width direction is parallel to the width direction of the positioning conveying device. The width direction and the first conveying direction are perpendicular to each other. The output end of the second belt conveyor 300 abuts against the first side or the second side of the first belt conveyor 200; or the second belt conveyor 300 has a plurality of, and the first side and the second side of the first belt conveyor 200 are each provided with the second belt conveyor 300. It should be understood that the first side and the second side are opposite. For example, when the express delivery article moves in the first conveying direction, the left side of the express delivery article is the first side, and the right side of the express delivery article is the second side; or when the express delivery article moves in the first conveying direction, the right side of the express delivery article is the first side, and the left side of the express delivery article is the second side.

[0041] As an optional implementation manner of the above embodiment, the included angle a formed by the first conveying direction and the second conveying direction is an acute angle. The first belt conveyor 200 moves along the first conveying direction and can provide the express delivery article with a first speed V1 parallel to the first conveying direction. The first belt conveyor 200 moves along the second conveying direction and can provide the express delivery article with a second speed V2 parallel to the second conveying direction. It should be understood that the conveying direction has directionality. The first speed V1 and the second speed V2 are both vectors. The included angle a formed by the first conveying direction and the second conveying direction is an acute angle, which can be understood as that the included angle a of the first speed V1 and the second speed V2 is an acute angle. Since the included angle a of the first conveying direction and the second conveying direction is an acute angle, when the express delivery article moves along the second conveying direction, it has a component motion parallel to the first conveying direction, so that the express delivery article can be smoothly transferred onto the first belt conveyor 200; and when the express delivery article moves along the second conveying direction, it can move at least a distance in the first conveying direction.

[0042] As an optional implementation of the above embodiment, the first belt conveyor 200 comprises a first belt, and the second belt conveyor 300 comprises a second belt. The width of the first belt is greater than the width of the second belt. The width of a belt refers to the dimension of the belt in the direction perpendicular to the conveying direction of the belt. The width of the first belt refers to the dimension of the first belt in the direction perpendicular to the first conveying direction. The width of the second belt refers to the dimension of the second belt in the direction perpendicular to the second conveying direction. In the positioning conveying device, the express item needs to be positioned and conveyed onto the first belt conveyor 200. The width of the first belt is mainly determined according to the maximum size of the express item that can be conveyed. The second belt serves to position the express item onto the first belt conveyor 200, and mainly serves to provide the express item with movement in the second conveying direction D2. The width of the second belt can be selected without considering the size of the express item. However, if the width of the second belt is designed to be large, since the second belt conveyor 300 and the first belt conveyor 200 are arranged in an inclined manner, the gap between the second belt conveyor 300 and the first belt conveyor 200 will be larger, the area required by the panel of the frame 100 will be larger, and the probability of the express item being damaged by friction and abrasion when transitioning from the second belt conveyor 300 to the first belt conveyor 200 will increase. Therefore, the smaller the width of the second belt, the smaller the probability of the express item being damaged by friction and abrasion when transitioning from the second belt conveyor 300 to the first belt conveyor 200. Therefore, the width of the first belt is greater than the width of the second belt.

[0043] In some optional implementations, the width of the second belt can be selected to be 154 mm or even smaller. The width of the first belt can be selected according to the size of the express item, and is only required to be greater than the width of the second belt conveyor 300, and is not specifically limited herein.

[0044] As an optional implementation of the above embodiment, the conveying surface defined by the first belt is arranged in the same plane as the conveying surface defined by the second belt. It should be understood that the conveying surface refers to the plane in which the express item contacts the belt. In this embodiment, when the express item transitions from the second belt to the first belt, the express item always moves in a plane and does not experience jolts, thereby improving the stability of conveying the express item.

[0045] As an optional implementation of the above embodiment, the first belt has a longer transmission distance than the second belt. The transmission distance of a belt refers to the maximum distance that the belt can move the parcel. The transmission distance of the first belt determines the maximum distance that the positioning conveyor can transport the parcel. The second belt mainly provides the parcel with a second conveying direction D2 movement, and its transmission distance only needs to meet the requirement of positioning and conveying the parcel to the first belt machine 200. Therefore, the transmission distance of the first belt is longer than that of the second belt. Moreover, when the parcel is transferred from the second belt machine 300 to the first belt machine 200, both the first belt machine 200 and the second belt machine 300 provide the parcel with a speed, and the speed direction of the parcel is not parallel to the first conveying direction D1. The parcel moves relative to the first belt and may have disordered movements such as tumbling and / or rolling. In order to avoid the adverse effects of the disordered movements on the subsequent sorting process, the transmission distance of the first belt is set to be relatively long. During the movement of the parcel, the longer the transmission distance of the first belt machine 200 is, the more time the parcel has to adjust in disorder. After the parcel adjusts in disorder, the parcel is positioned on the first belt machine 200 and can remain relatively stationary relative to the first belt machine 200, so that the parcel can be stably conveyed to the next sorting device.

[0046] As an optional implementation of the above embodiment, the frame 100 has a cargo input end, the first input end of the first belt machine 200 is connected to the cargo input end, and the second input end of the second belt machine 300 is connected to the cargo input end. The cargo input end refers to the end at which the cargo enters the positioning conveyor. The first input end refers to the starting end of the first belt machine 200. The second input end of the second belt machine 300 refers to the starting end of the second belt machine 300. This arrangement is mainly to enable the parcel to have one of the following movement conditions when it is delivered to the positioning conveyor:

[0047] The first belt machine 200 conveys the parcel along the first transmission direction to the scanning and identifying module and / or the directional sorting module;

[0048] The second belt machine 300 moves the parcel along the second transmission direction to the first belt machine 200, so that the parcel can be positioned and conveyed back to the first belt machine 200, and the first belt machine 200 conveys the parcel along the first transmission direction to the scanning and identifying module and / or the directional sorting module;

[0049] The first belt machine 200 conveys the parcel along the first transmission direction, and at the same time, the second belt machine 300 also conveys the parcel along the second transmission direction until the parcel is entirely located on the first belt machine 200, and then the first belt machine 200 conveys the parcel along the first transmission direction to the scanning and identifying module and / or the directional sorting module.

[0050] It should be noted that since the number of second belt conveyors 300 can be many, the second input end of the second belt conveyor 300 being connected with the goods input end can be understood as the input end of the second belt conveyor 300 closest to the goods input end of the frame 100 being connected with the goods input end.

[0051] In combination Figure 1 As shown in the following embodiments, a positioning conveying device for edge conveying is provided.

[0052] In the prior art, an edge positioning conveying device is used to move the express parcel along the conveying direction against the edge of the device. When the express parcel is transported through the edge positioning conveying device, the express parcel will be in contact with the edge of the conveying device, and even be pressed, so that the express parcel has a deformation tension; after the deformation of the express parcel is recovered, the express parcel is easily hung by the side baffle of the sorting module, which affects the normal sorting. Therefore, in order to prevent the express parcel from being tightly attached to the side wall of the conveying device, as an optional implementation manner of the above embodiment, a third belt conveyor 400 is arranged on the first side, the third belt conveyor 400 has a third conveying direction D3, and the included angle between the first conveying direction and the third conveying direction is 1° to 5°. The positioning conveying device thus arranged is used for edge conveying of the express parcel. At this time, since the included angle between the first conveying direction and the third conveying direction is 1° to 5°, when the express parcel is transferred from the third belt conveyor 400 to the first belt conveyor 200, the express parcel has a small speed perpendicular to the first conveying direction D1, so that the express parcel only moves a very short distance towards the first belt conveyor 200; although the express parcel only moves a very short distance towards the first belt conveyor 200, the third belt conveyor 400 still drives the express parcel to move towards the first belt conveyor 200 and away from the side wall, thereby being able to reduce the interaction force between the express parcel and the side wall of the positioning conveying device, avoid the express parcel being tightly attached to the side wall of the positioning conveying device, and avoid the express parcel being excessively pressed to generate deformation.

[0053] Generally, the third belt conveyor 400 includes a third belt, a driving roller and a transmission roller for driving the third belt to move, and a driving mechanism for driving the driving roller to rotate. The driving mechanism is a device capable of realizing rotary motion, such as a direct drive motor, a common motor cooperating with a gear reduction device, or a common motor cooperating with a worm and gear device, etc. The driving mechanism is generally connected with the frame 100 and located on the side of the belt facing the ground. The width of the third belt is smaller than the width of the first belt. Generally, the width of the third belt is as small as possible.

[0054] As an optional implementation of the above embodiment, the second side of the first belt conveyor 200 is provided with at least one second belt conveyor 300. The first side of the first belt conveyor 200 is provided with a third belt conveyor 400 for avoiding pressing the express item. The second side of the first belt conveyor 200 is provided with at least one second belt conveyor 300. If the included angle a between the second conveying direction and the first conveying direction is small, the width of the input end of the edge positioning conveying device is small, which is not conducive to receiving the express item and affects the delivery of the express item to the edge positioning conveying device. If the included angle a between the second conveying direction and the first conveying direction is large, the express item has a large speed V 2y perpendicular to the first conveying direction D1, and a small speed V 2x parallel to the first conveying direction D1. When the express item is transferred from the second belt conveyor 300 to the first belt conveyor 200, there may be disordered motion such as overturning or turning. Therefore, the included angle a between the second conveying direction and the first conveying direction is 30° to 60°.

[0055] In some embodiments, in order to simultaneously consider the conveying capacity of the edge positioning conveying device and reduce the probability of disordered motion of the express item, the included angle a between the second conveying direction and the first conveying direction is 45°, at which time the express item can be more gently transferred from the second belt conveyor 300 to the first belt conveyor 200.

[0056] Further, it needs to be noted that, since the included angle a between the second conveying direction and the first conveying direction is 30° to 60°, when the express item is transferred from the second belt conveyor 300 to the first belt conveyor 200, it will move a distance along the first conveying direction D1 under the action of the second speed V2 provided by the second belt conveyor 300. The width of the second belt conveyor 300 is small, and the number of the second belt conveyors 300 can be many, such as 2, 3, 4, …, N (N is a positive integer). The specific value of N is mainly determined according to the maximum size of the express item. The larger the maximum size of the express item, the larger the specific value of N. When N is greater than or equal to 2, the plurality of second belt conveyors 300 are arranged in sequence along the first conveying direction D1, and the second conveying directions D2 of the plurality of second belt conveyors 300 are parallel.

[0057] In combination with Figure 2 , the embodiment provides a positioning conveying device for center conveying.

[0058] The positioning conveying device for center conveying is different from the positioning conveying device for edge conveying in that the first belt conveyor 200 is centrally arranged, and at least one second belt conveyor 300 is arranged on each side of the first belt conveyor 200. That is, there are at least two second belt conveyors 300, and at least one second belt conveyor 300 is arranged on the opposite sides of the first belt conveyor 200.

[0059] If the angle a between the second conveying direction of the second belt conveyor 300 on both sides and the first conveying direction is large, the parcel has a large speed V 2y perpendicular to the first conveying direction D1, and a small speed V 2x parallel to the first conveying direction D1, and the parcel can be flipped or turned when it is transferred from the second belt conveyor 300 to the first belt conveyor 200. Therefore, the angle a between the second conveying direction of the second belt conveyor 300 on both sides and the first conveying direction is 30° to 60°.

[0060] In some embodiments, in order to simultaneously consider the conveying capacity of the edge positioning conveying device and reduce the probability of disordered movement of the parcel, the angle a between the second conveying direction of the second belt conveyor 300 on both sides and the first conveying direction is 45°, and at this time, the parcel can be more gently transferred from the second belt conveyor 300 to the first belt conveyor 200.

[0061] In some embodiments, the second belt conveyor 300 on both sides can be symmetrically arranged or asymmetrically arranged. For example, the angle a between the second conveying direction D2 of the second belt conveyor 300 on the first side and the first conveying direction D1 is 40°, and the angle a between the second conveying direction D2 of the second belt conveyor 300 on the second side and the first conveying direction D1 is 45°.

[0062] Taking the first side as the left side and the second side as the right side as an example, the working process of the center conveying positioning conveying device is described. It should be understood that when the parcel is delivered to the center conveying positioning conveying device, there are mainly five position conditions: only on the first belt conveyor 200, only on the second belt conveyor 300 on the left side, only on the second belt conveyor 300 on the right side, only on the first belt conveyor 200 and the second belt conveyor 300 on the left side, and on the first belt conveyor 200 and the second belt conveyor 300 on the right side.

[0063] When the parcel is only on the first belt conveyor 200, the first belt conveyor 200 transports the parcel centrally along the first conveying direction D1.

[0064] When the parcel is only on the second belt conveyor 300 on the left side or the right side, the second belt conveyor 300 on the corresponding side positions and conveys the parcel to the first belt conveyor 200 along the second conveying direction D2, and the first belt conveyor 200 centrally transports the parcel along the first conveying direction D1.

[0065] When the parcel is on the second belt conveyor 300 on the left side and the first belt conveyor 200 at the same time, the parcel has a first speed V1 along the first conveying direction D1 and a second speed V2 along the second conveying direction D2 at the same time, and the combined speed V合 The second belt conveyor 300 can also positionally convey the mail piece along the second conveying direction D2 to the first belt conveyor 200, and the first belt conveyor 200 can convey the mail piece along the first conveying direction D1.

[0066] When the mail piece is positioned on the second belt conveyor 300 and the first belt conveyor 200 at the same time, the mail piece has a first speed V1 along the first conveying direction D1 and a second speed V2 along the second conveying direction D2 at the same time, and the resultant speed V of the first speed V1 and the second speed V2 is greater than the first speed V1. 合 The second belt conveyor 300 can also positionally convey the mail piece along the second conveying direction D2 to the first belt conveyor 200, and the first belt conveyor 200 can convey the mail piece along the first conveying direction D1.

[0067] Optionally, at least two second belt conveyors 300 are arranged on one side of the first belt conveyor 200, and the at least two second belt conveyors 300 are arranged in sequence along the first conveying direction.

[0068] It can be understood that, since the included angle a between the second conveying direction of the second belt conveyor 300 arranged on both sides and the first conveying direction is 30° to 60°, when the mail piece is transferred from the second belt conveyor 300 to the first belt conveyor 200, the mail piece will move a distance towards the first conveying direction D1 under the action of the second speed V2 provided by the second belt conveyor 300, and generally the width of the second belt conveyor 300 is small, so the number of the second belt conveyors 300 arranged on either side or both sides can be many, such as 2, 3, 4, …, N (N is a positive integer). The specific value of N is mainly determined according to the maximum size of the mail piece, and the larger the maximum size of the mail piece, the larger the specific value of N. When N is greater than or equal to 2, the second belt conveyors 300 arranged on both sides are arranged in sequence along the first conveying direction D1, and the second conveying directions D2 of the plurality of second belt conveyors 300 on each side are parallel.

[0069] In addition, it can be understood that, since the second belt conveyor 300 of the positionally conveying device for center conveying can drive the mail piece a distance towards the first belt conveyor 200, the mail piece will not be squeezed against the edge of the positionally conveying device.

[0070] The above describes in detail the positionally conveying device provided by the embodiments of the present application, and the principles and implementation manners of the present application are described by applying specific examples, and the above description of the embodiments is only used to help understand the method of the present application and the core idea thereof; meanwhile, for those skilled in the art, the specific implementation manner and application range of the present application can be changed according to the idea of the present application, and in view of the above, the content of the description should not be understood as a limitation of the present application.
