Detailed Description

The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.

In the prior art, when the luggage is switched among different sliding sections in the sliding process, the luggage can fall due to the sudden change of the inclination angle among the sections of the sliding groove, so that the luggage is damaged.

Referring to fig. 3 to 6, an embodiment of the present invention provides a baggage conveying chute, wherein a chute body of the baggage conveying chute is at least partially made of a flexible material. Based on this arrangement, the flexible portion of the chute body can be elastically deformed to some extent. Luggage 11 receives the tipping of letter sorting mechanism tipping tray 12, when falling on spout main part 2, because the weight of luggage itself, the flexible portion of spout main part can take place a certain amount of deformation, luggage is constantly diminishing at the inclination of the flexible portion of decline in-process spout main part, so luggage constantly reduces along the gravity component of spout direction, luggage speed reduces gradually under the unchangeable condition of coefficient of friction, luggage slows down the effect at whole landing in-process obviously, difficult emergence collision between the luggage. And because the spout main part is flexible, the condition that collision with the luggage leads to luggage damage can not take place. In particular, the chute body may be divided into a plurality of flexible sections and rigid sections arranged at intervals, the flexible sections may be made of a flexible material, the rigid sections are made of a non-deformable rigid material, and adjacent flexible sections and rigid sections are connected to each other.

In some embodiments, the chute body 2 of the baggage conveying chute is made entirely of a flexible material. The sliding chute main body 2 is integrally made of flexible materials and has certain elastic deformation capacity. Luggage 11 receives the tipping of letter sorting mechanism tipping tray 12, and when dropping onto spout main part 2, because the weight of luggage itself, a certain amount of deformation can take place for flexible spout main part, and luggage is constantly diminishing at the inclination of decline in-process spout main part, and luggage is constantly reduced along the gravity component of spout direction so, and luggage speed reduces gradually under the unchangeable condition of coefficient of friction. As shown in fig. 3 (the receiving section is not shown in fig. 3), in the process that the luggage slides along the chute main body, when the luggage slides to the point a on the chute main body, the chute main body deforms under the action of the gravity of the luggage, so that the chute main body forms two inclined planes on two sides of the point a respectively, and the two inclined planes incline in the direction from the higher end of the chute main body to the lower end of the chute main body, then the luggage continues to slide, and when the luggage slides to the point B, the chute main body also forms two inclined planes on two sides of the point B respectively, and then the luggage continues to slide to the point C. The inclination angle of the chute main body and the horizontal plane is smaller and smaller in the process that the luggage slides down from the point A to the point C, namely, the acceleration of the luggage subjected to deceleration is larger and larger, and finally the speed is minimum when the luggage approaches to the extraction section (the end with the lower height of the chute main body). The luggage has obvious deceleration effect in the whole sliding process, and the luggage is not easy to collide. And because the spout main part is flexible, the condition that collision with the luggage leads to luggage damage can not take place. It should be noted that the chute body is in a tensioned state in fig. 4 to 6.

In some examples, the flexible material comprises a silicone sheet, an elastic polyurethane sheet, or a rubber material. Silica gel board, elasticity polyurethane board or rubber materials all possess certain elastic deformation ability, can take place elastic deformation under the luggage action of gravity, and then avoid bumping with luggage, avoid the luggage damage, because coefficient of friction is great, can improve the speed reduction effect to luggage, silica gel board still can keep great coefficient of friction under the condition of trickle in addition, guarantees that luggage has good speed reduction effect. Meanwhile, the silica gel plate, the elastic polyurethane plate and the rubber material have certain elastic deformation capacity, and also have certain wear resistance and flame retardance, so that the luggage conveying chute prepared from the materials has good durability. The flexible material can also adopt other materials with certain elastic deformability, wear resistance and flame retardance.

In some examples, the back of the chute body is layered with a flexible wire mesh. The flexible wire mesh is used as a cushion layer of the silica gel plate, so that certain support can be provided for the silica gel plate, and the excessive deformation of the sliding groove main body is avoided. The flexible metal wire mesh also has certain deformability, and normal deformation of the sliding chute main body is avoided being influenced. Preferably, the flexible wire mesh may be selected from a lower mesh stainless steel wire mesh. The wire mesh with lower mesh number can keep enough deformability, and the stainless steel material is easy to use in outdoor environment and can keep longer service life.

In the prior art system, the long-time use of the sliding chute can lead to the change of the friction coefficient of the sliding chute, the friction coefficient of the sliding chute can be influenced by the change of the external environment (such as temperature and water vapor), and the sliding speed of the luggage can not be controlled frequently due to the factors. Based on this, the embodiment of the invention provides a tension adjusting device for adjusting the chute tension in the process of the luggage sliding along the chute main body so as to control the sliding speed of the luggage.

With continued reference to fig. 4 to 9, the luggage conveying chute further includes a tension adjusting device, one end of the chute main body 2 is fixed, and the other end of the chute main body 2 is connected to the tension adjusting device, and the tension adjusting device drives the other end of the chute main body 2 to move towards or away from one end of the chute main body 2, so as to change the tension of the chute main body 2.

The position of the other end of the chute main body relative to one end of the chute main body determines the tension of the chute main body, and the difference of the tension means that the deformation quantity of the chute main body can be different when the luggage with the same weight falls on the chute, so that the included angle between the chute main body and the ground is changed, namely the luggage sliding speed is changed. In short, as the luggage slides down the chute body, the tension of the chute body determines the sliding speed of the luggage. Therefore, the sliding speed of the luggage can be controlled by changing the tension of the sliding groove main body, so that the purposes of reducing collision among the luggage and effectively reducing luggage retention are achieved. Specifically, luggage slides down along the spout main part, and when the other end of tension adjusting device drive spout main part moved to the direction that is close to the one end of spout main part, the deformation volume that the spout main part can take place became big, and the sliding speed of luggage can reduce, and correspondingly, when the other end of tension adjusting device drive spout main part moved to the direction of keeping away from the one end of spout main part, the deformation volume that the spout main part can take place became little, and the sliding speed of luggage can increase. In other words, if luggage cannot slide down on the chute main body, the tension adjusting device can drive the other end of the chute main body to move towards the direction far away from one end of the chute main body; if the luggage slides down too fast, the tension adjusting device can drive the other end of the sliding chute main body to move towards the direction close to one end of the sliding chute main body.

According to the embodiment of the invention, the tension of the sliding chute main body can be changed according to the real-time sliding speed of the luggage and the weight of the luggage, the influence of various environments on the friction coefficient of the sliding chute main body is adapted, the sliding speed of the luggage is further controlled, and the purpose of protecting the luggage and not retaining the luggage is finally achieved.

In some embodiments, the tension adjusting apparatus includes a moving member and an elastic member, the moving member is disposed in a movable manner in a direction approaching or separating from one end of the chute body, one side of the moving member is connected to the other end of the chute body, one end of the elastic member is connected to the other side of the moving member, and the other end of the elastic member is fixedly disposed.

Specifically, when luggage glides to the initial position of spout main part, under the action of the gravity of luggage, the spout main part takes place to warp, spout main part pulling moving member moves to the left side, the moving member moves to the left side from its initial position, along with the left side shift of moving member, elastic element is stretched, when luggage slides to a certain position in the middle of the spout main part, elastic element reaches the biggest tensile state, later under the action of luggage gravity, luggage continues to slide to the right side along the spout main part, the focus of luggage moves to the right side, the spout main part continues to warp, the moving member begins to move to the right side under the action of spring tension, the tensile volume of spring reduces gradually. In addition, in the process that the moving piece moves towards the right side, the sliding chute main body is also dragged to be relatively unfolded, so that the deformation quantity of the part of the sliding chute main body, which bears the luggage, is reduced, and the luggage can be helped to continuously move towards the right side. When the luggage slides to the other end of the chute main body (which can also be understood as an extraction section of the chute main body), the moving member returns to the initial position again. In some examples, the resilient element is in a free state when the chute body is not loaded with luggage. Here, the above-mentioned left and right movement is with respect to fig. 6 and 7, and it can be understood that the movement of the moving member to the left corresponds to the movement of the other end of the chute main body to a direction close to one end of the chute main body, and accordingly, the movement of the moving member to the right corresponds to the movement of the other end of the chute main body to a direction away from one end of the chute main body.

The tension adjusting device provided by the embodiment of the invention comprises the moving part and the elastic element, wherein the moving distance and the moving speed of the moving part are jointly determined by the elastic performance and the number of the elastic element and the weight of the luggage.

In particular, the moving member may be realized by a movable slider 8 mounted at the end of the chute body. The tail end of the sliding chute main body 2 is additionally provided with a sliding block 8 which can move left and right to be connected with the sliding chute main body 2, so that the tension of the sliding chute main body can be adjusted. If luggage can not slide downwards, the sliding block moves rightwards, and if the luggage slides downwards too fast, the sliding block moves leftwards. Through the removal of control slider, influence the landing speed of luggage in the spout main part, effectively reduce the collision between luggage to effectively solve the delay problem of luggage in the spout main part. The elastic element may be realized by a spring. The moving distance and the moving speed of the slide block are determined by the elastic performance of the spring, the number of the springs and the weight of the luggage.

In some embodiments, one end of the chute body is a higher height end and the other end of the chute body is a lower height end. Namely, the tension adjusting device is arranged at one end with lower height of the chute main body and is connected with the end with lower height. The tension adjusting device can be arranged on the ground and is beneficial to adjusting the tension of the sliding chute main body.

In some embodiments, the luggage conveying chute further comprises a skid plate 1, the skid plate 1 being connected to one end of the chute body 2. In particular, the slide 1 is made of a non-deformable plate material as a receiving section of a baggage conveyor chute for carrying baggage conveyed down by the sorting mechanism. The luggage slides to the flexible chute main body which can elastically deform after passing through the sliding plate.

In some embodiments, the baggage conveyor chute further comprises a bracket 6, wherein the bracket 6 is arranged below the sliding plate 1 and supports the sliding plate 1.

In some embodiments, the tension adjusting apparatus further includes a guide rail 9 provided near the other end of the chute body, and the moving member is slidably provided on the guide rail 9. A guide rail 9 may be arranged near the lower end of the chute body in height, the guide rail 9 serving to define a moving path of the moving member. In addition, a limiting structure can be further arranged on the guide rail and used for limiting the maximum stroke of the moving piece. Here, the maximum stroke of the moving member includes a maximum stroke of the moving member moving in a direction approaching one end of the chute main body and a maximum stroke of the moving member moving in a direction away from one end of the chute main body. The maximum travel of the moving member to the direction of being close to the one end of the chute main body can be set to be, when the moving member is located to the maximum travel of the direction of being close to the one end of the chute main body, for luggage of any weight, in the process that the luggage slides along the chute main body, the chute main body provides two inclined planes by taking the position of the luggage as a boundary, and the inclination directions of the two inclined planes are all from the higher end of the chute main body to the lower end of the height of the chute main body, so that the luggage can continuously slide to the lower end (namely, the extraction section) of the height of the chute main body. The maximum stroke of the moving member moving in the direction away from one end of the sliding chute main body can be set to be in a tensioning state when the moving member is at the maximum stroke of the moving in the direction away from one end of the sliding chute main body, and at the moment, the sliding chute main body integrally provides an inclined plane. The limiting structure on the guide rail can be realized by a support bearing which is fixed on the ground by the guide rail.

With continued reference to fig. 4-9, in one specific embodiment, the baggage conveyor chute is comprised of a receiving section slide 1, a chute body 2, a fixed platform 3, unpowered rollers 4, a concrete platform 5, brackets 6, support bearings 7, sliders 8, and guide rails 9 (spring brackets for fixing the right side of the spring are not shown in fig. 7-9). The cement platform 5 is arranged on the horizontal ground and used for fixing the whole sliding chute supporting bracket, and the receiving section is arranged above the bracket 6 and is fixed. The moving member may be implemented by a movable slider installed at the end of the chute body. The slider 8 sets up in the below of fixed platform 3, and the extending direction setting of guide rail 9 parallel to the spout main part, and slider 8 overlaps on the guide rail with the mode that can follow the guide rail gliding, and guide rail 9 passes through support bearing 7 to be fixed subaerial. The left side of fixed platform 3 is connected with the spout main part, and the right side of fixed platform 3 is connected with spring 10, and the spring right side is connected to a spring bracket, and this spring bracket can be fixed in ground. When no luggage is placed on the luggage conveying chute, the fixed platform 3 and the unpowered roller 4 are connected with each other, the sliding block is at an initial position, and the spring is in a free state.

Specifically, when the luggage slides to the starting position of the sliding chute main body, the sliding chute main body deforms under the action of the gravity of the luggage, the sliding chute main body pulls the sliding block to move towards the left side, the sliding block moves towards the left side along the guide rail from the initial position of the sliding block, the spring is stretched along with the left movement of the sliding block, when the luggage slides to a certain position in the middle of the sliding chute, the spring reaches the maximum stretching state, then under the action of the gravity of the luggage, the luggage continues to slide towards the right side along the sliding chute main body, the gravity center of the luggage moves towards the right side, the sliding chute continues to deform, the sliding block starts to move towards the right side under the action of the tension of the spring, and the stretching amount of the spring is gradually reduced. In addition, in the process that the sliding block moves towards the right side, the sliding groove main body is also dragged to be relatively unfolded, so that the deformation of the part of the sliding groove main body, which bears the luggage, is reduced, and the luggage can continue to move towards the right side. When luggage slides to spout main part bottom, the slider gets back to initial position again to fixed platform and unpowered roller link up each other this moment for luggage can directly slide to unpowered roller along fixed platform on. At the moment, the sliding block is at the initial position, the fixed platform and the unpowered roller are mutually connected, and the spring is in a free state.

The moving member can also be driven by a driving mechanism. In some examples, the moving member may be implemented by a movable slider mounted at an end of the chute body. The moving position and the moving speed of the sliding block are controlled by a motor, and the moving position of the sliding block determines the integral tension of the sliding chute, so that the deformation quantity generated by the sliding chute main body is changed. Here, the motor may be another linear driving mechanism, such as an air cylinder, as long as the slider can be driven to move in the horizontal moving direction of the luggage.

Specifically, the slider sets up in the below of fixed platform, and the slider overlaps on the guide rail with the mode that can follow the guide rail slip, and the guide rail passes through support bearing and fixes subaerial. The sliding block is connected to the motor through a transmission mechanism and can slide along the guide rail under the drive of the motor.

When the luggage slides to the starting position of the sliding groove main body, the sliding groove main body deforms under the action of the gravity of the luggage, the motor drives the sliding block to move towards the left side from the initial position of the sliding groove main body along the guide rail, so that the deformation quantity which can be sent by the sliding groove main body is increased, when the luggage slides to a certain position in the middle of the sliding groove main body, the luggage continuously slides towards the right side along the sliding groove main body, the gravity center of the luggage moves towards the right side, the sliding groove main body continuously deforms, and the sliding block can start to move towards the right side under the driving of the motor. In addition, in the process that the sliding block moves towards the right side, the sliding groove main body is also dragged to be relatively unfolded, so that the deformation of the part of the sliding groove main body, which bears the luggage, is reduced, and the luggage can continue to move towards the right side. When luggage slides to the bottom of spout main part, the slider is got back to initial position again under motor drive to fixed platform and unpowered roller link up each other this moment for luggage can be directly along fixed platform slip to unpowered roller on. In the sliding process of the luggage along the sliding chute main body, the sliding block is driven to move by the motor, so that the deformation of the sliding chute main body under the action of the gravity of the luggage can be changed, and the sliding speed of the luggage can be adjusted.

In some embodiments, the tension adjusting apparatus further includes a speed detecting mechanism, the speed detecting mechanism is configured to detect a sliding speed of the luggage placed on the chute main body, and the driving mechanism is configured to drive the moving member to move toward or away from one end of the chute main body according to the sliding speed of the luggage detected by the speed detecting mechanism.
