Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material transportation, in particular to the technical field of vertical material transportation, and specifically to a high-falling object impact protection transfer method. BACKGROUND

[0002] In the process of transporting goods, it is often necessary to transport goods from a certain height downward. In the current technology, the downward transportation of goods from a high place is generally achieved by using a slide, a downward conveyor belt, a vertical goods elevator, etc. However, the above methods require a large area, and the transportation speed is generally relatively slow due to safety considerations. Otherwise, the transmission machinery is easily damaged. For large quantities of goods, the above methods are not ideal, especially if the goods are in the form of strips. The above methods are not suitable for transporting goods, which can easily cause irregular stacking of products, resulting in waste of space and the need for subsequent manual or mechanical secondary sorting operations, which is not conducive to efficient product circulation. Therefore, when operating in some production places, the goods are directly dropped from the upper area, a flexible receiving mechanism is arranged in the lower area, and the goods are immediately transported away after being transported, leaving space for the next goods to fall. However, this method still has problems such as damage to goods and irregular stacking. Therefore, a better way is needed to solve the above problems and improve the material transportation problem caused by the adaptation of special goods conveying environment. SUMMARY

[0003] In view of the above problems, the present application provides a high-falling object impact protection transfer method. A rotating speed reducer is arranged to adjust the rotating speed according to the falling speed of the goods, so that it can better adapt to the scene, achieve high-speed circulation of goods without damaging the goods, and realize vertical to horizontal circulation of goods.

[0004] A high-falling object impact protection transfer method uses the above-mentioned high-falling object impact protection transfer device, which includes a rotating speed reducer, a platform support, a steering skid, and a control system. The rotating speed reducer is a rotatable structure with a speed reducer shaft in the middle. A transmission connecting device is arranged on the platform support. The speed reducer shaft is installed on the transmission connecting device. The rotating speed reducer includes a plurality of bearing parts arranged along the speed reducer shaft in the axial direction, which are used to bear and buffer the goods. A horizontal speed reducer is connected to the bottom of the steering skid. The horizontal speed reducer is used to receive the goods released from the rotating speed reducer and recover them to a designated area.

[0005] The method includes the following steps:

[0006] S1, a high place falling object impact protection transmission device is transported to the position of receiving the falling object from high place, and is adjusted to the appropriate position, ensuring that the falling object from the fixed position of high place can fall to the end of the receiving part according to the required angle;

[0007] S2, start working, first release the falling object from high place through other mechanism, and start falling, so that it falls to the receiving part, at this time the control system obtains the speed of the falling object falling to the receiving part through measurement and calculation, and sends a command to make the rotary reducer rotate according to the speed, so that the falling object does not impact or bounce after falling to the receiving part, and the cover is automatically buckled after the falling object falls to the receiving part, and the falling object rotates with the receiving part on the rotary slide, changing the vertical impact force into horizontal motion force; the receiving part and the cover rotate to the tangent position of the track slide and the horizontal deceleration belt after grabbing the falling object;

[0008] S3, when the object comes to the rotary slide area and runs to the horizontal decelerator, the rotary decelerator continues to rotate upward, so that the object leaves the limit of the rotary decelerator, due to inertia, the object will continue to move on the horizontal decelerator, at this time the horizontal decelerator keeps rotating at a certain speed, so that the object slowly stops on the horizontal decelerator under the action of friction, and the speed of the horizontal decelerator can be adjusted according to the needs, and the object is sent to the outlet end through the horizontal decelerator for unified arrangement and storage;

[0009] In the step S2, the control system measures and calculates the speed of the falling object, including the following steps:

[0010] Let the range finder be point A, the outlet end of the object from high place be point C, the receiving part at the horizontal position directly below the object from high place be point D, and the speedometer be point B, wherein point B and point D are at the same horizontal position, the straight line distance between point A and point C is L1, the horizontal distance between point A and point D is L2, the straight line distance between point A and point D is L3, the vertical distance between point A and point D is h1, and the acute angle between AD straight line and the horizontal line where BD is located is θ1; g is the acceleration of gravity, 9.8 m / s 2 ;

[0011] From the above geometric relations, we can get:

[0012] The angle between AD and CD is

[0013] From the right triangle relation, we can get:

[0014]

[0015] From the cosine theorem, we can get:

[0016]

[0017] And because:

[0018]

[0019] get:

[0020]

[0021] By the law of conservation of energy, let the initial velocity of the object as it falls vertically from point C to point D be V0, and its velocity at point D be V1. We can then obtain V1:

[0022]

[0023] The time t for the object to fall vertically to the horizontal height of point D can be obtained from the following formula:

[0024]

[0025] Based on the above calculations, the velocity of the item at point D is obtained. Then, the velocity V of the rotary reducer that needs to be matched at point D is calculated. D To achieve V1±5% and ensure that the rotary reducer reaches point D exactly when the item lands, the calculation process includes the following steps:

[0026] Let the rotation center of the rotary reducer be point O, the receiving part at the horizontal position directly below the high object be point D, the rotation radius of the rotary reducer be L, and the rotation speed be n1;

[0027] We can obtain:

[0028] ω=2πn

[0029]

[0030] v=ωr

[0031] Rotary reducer rotational angular velocity:

[0032] ω1=2πn1

[0033] Velocity of the receiving part at point D:

[0034] V D =ω1L

[0035] V D =2πn1L

[0036] The time it takes for the item to fall to the horizontal height of point D, calculated from the previous steps, is:

[0037]

[0038] Furthermore, because the rotary reducer has four receiving parts, we can conclude that:

[0039] (N is a positive integer)

[0040] Wherein T is the fixed rotation period of the rotary reducer:

[0041]

[0042] Therefore, under the condition that the initial falling height of the article is unchanged, T can be kept unchanged, and the rotary reducer can be kept rotating as needed to run smoothly, but the control system, the speedometer and the range finder still need to be kept on to ensure real-time monitoring of the speed of the new falling article.

[0043] Further, each receiving part is attached to the inner side of the turning slide at the end away from the rotary shaft of the reducer; the turning slide is an arc structure for guiding the turning of the article, and the center of the circle is concentric with the axis of the rotary shaft of the reducer. When the receiving part rotates under the driving of the rotary shaft of the reducer, it always keeps one end in contact with the inner wall of the turning slide.

[0044] Further, a speedometer and a range finder are also provided, the speedometer is installed on the top of the turning slide, and the range finder is installed on the axis plane of the speedometer and the rotary shaft of the reducer, and keeps a distance from the speedometer.

When it is partially covered, the guard plate can be connected to any two adjacent receiving parts to ensure that the receiving part and the previous receiving part form a relatively closed space, while the other receiving parts form an open space.

[0047] Further, the receiving part is provided with a cover at the position adjacent to the turning slide, the cover is connected to the end of the receiving part through an electric control shaft and rotates through the electric control shaft, and a torsional spring is also provided on the electric control shaft to keep the electric control shaft in an open state when it is not working, so that the entire receiving part remains in an open form;

[0048] The receiving part is composed of multiple arc segments, and the size of the arc segment matches the cover; a flexible layer is provided on the surface of the receiving part to provide a buffering force;

[0049] An electric resistance film pressure sensor is provided inside the receiving part, which can drive the electric control shaft to automatically cover the receiving part with the cover when the article falls into the receiving part.

[0050] Further, the horizontal decelerator is a conveying belt, the end of which is circular arc-shaped, the bottom of the steering skid is matched with the horizontal decelerator and is concave semicircular, the end of the steering skid is concave to allow the horizontal decelerator to be put in, and the gap between the bottom of the steering skid and the horizontal decelerator is ensured to be small; the horizontal decelerator is provided with a rotary motor to drive the horizontal decelerator to move at a required speed; other conveying belts or receiving boxes can be connected at the end of the horizontal decelerator to receive the transported articles.

[0052] Further, the number of the receiving parts is four, and the receiving parts are all connected on the rotary shaft of the decelerator and form a cross-shaped structure in the side section.

[0053] Further, the falling speed of the article is monitored in real time by the speed detector in the process of step S2, and the rotating speed of the rotary decelerator is corrected synchronously.

[0087] In the present application, a speedometer 8 and a range finder 7 are also provided, both of which are existing technical solutions of laser speed measurement and laser ranging, preferably, the speedometer 8 is installed at the top of the steering skid 5, the range finder 7 is installed on the axis plane of the speedometer 8 and the reducer rotating shaft 104, and keeps a distance from the speedometer 8, so that the speedometer 8 and the range finder 7 can be in the same plane as the midpoint of the falling objects 10 above, and the objects 10 are always in this plane during the falling process.

[0088] The inner side of the transmission connection device 201 is provided with a guard plate 102, the inner side surface of the guard plate 102 is in close contact with and connected to the receiving part 101, and the guard plate 102 rotates synchronously with the rotary speed reducer 1;

[0089] The guard plate 102 is fully covered or partially covered, when it is fully covered, the guard plate is a circular plate covering the side surface of the entire receiving part 101; in this case, it can be ensured that all the articles 10 falling down are located in a relatively closed area, and even if the left and right movements occur accidentally, they can be controlled within the range;

[0090] When it is partially covered, the guard plate 102 can be connected to any two adjacent receiving parts 101 to ensure that the space between the receiving part 101 and the previous receiving part 101 is relatively closed, while the spaces between other receiving parts 101 are open spaces; in this way, it can be ensured that the part of the open space can receive articles 10 with a width greater than the distance between the two oppositely arranged guard plates 102, so as to improve the application range of the application.

[0091] The receiving part 101 is provided with a buckle cover 103 adjacent to the steering sliding table 5, the buckle cover 103 is connected to the end of the receiving part 101 through an electric control shaft 105, and rotates through the electric control shaft 105; a torsional spring can also be provided on the electric control shaft 105, so that the electric control shaft 105 remains in an open state when it is not working, and the entire receiving part 101 remains in an open form;

[0092] In some embodiments, the buckle cover 103 can have other shapes, which are replaced and adapted according to the structure of the object to be received, and the end of the receiving part 101 can also be replaced and adapted, for example, as shown in Figure 14 The box-shaped structure is adapted to irregularly shaped objects, rather than being limited to strip-shaped structures, and a grabber 1031 can be provided at the end of the box-shaped structure to tighten the articles after receiving them, and to adapt to articles of different sizes.

[0093] The receiving part 101 is composed of a plurality of arc-shaped segments, and the size of the arc-shaped segments is matched with the buckle cover 103; a flexible layer is provided on the surface of the receiving part 101 to provide a buffering force; a plurality of arc-shaped segments are used because each arc-shaped segment can be assembled and disassembled, and the connection can be achieved by using a bolt-fixed way or other similar solutions for detachable connection, but the outermost buckle cover 103 needs to be kept at the outermost end to adapt to articles falling from different heights; when the height is small, a smaller number of arc-shaped plates are needed to ensure smooth operation. In other embodiments, the receiving part 101 except the last one contacting the buckle cover 103 can be kept as an arc, and the previous ones can be replaced by a whole flat plate and connected to the rotary shaft 104 of the speed reducer.

[0094] Inside the receiving part 101 is a resistance film pressure sensor (not shown in the figure), when the article falls into the receiving part 101, the electric control shaft 105 can also be driven to automatically drive the cover 103 to cover the receiving part 101.

[0095] The horizontal speed reducer 6 is a conveyor belt, the end thereof is circular arc-shaped, the bottom of the turning sliding platform 5 is matched with the horizontal speed reducer 6, and is inwardly recessed to be semicircular, as shown in the figure, the end of the turning sliding platform 5 is recessed to allow the end of the horizontal speed reducer 6 to be put in, so as to ensure that the gap between the bottom of the turning sliding platform 5 and the horizontal speed reducer 6 is small; the horizontal speed reducer 6 is provided with a rotating motor, which drives the horizontal speed reducer 6 to move at a required speed; the end of the horizontal speed reducer 6 can be connected with other conveyor belts or receiving boxes to receive the transported articles 10, so as to ensure that the articles 10 can be best received. Figure 13

[0096] The moving platform 3 is further provided below all the above-mentioned devices, the moving platform 3 is internally provided with damping springs, which can provide a better damping effect when receiving articles; the moving platform 3 is provided below with moving wheels 301 and is provided with a moving controller 302, which can drive the whole moving platform 3 to freely move; the moving wheels 301 are provided with a support platform, the material of the support platform is foamed aluminum, because the foamed aluminum material has a good impact absorbing capacity, so as to ensure that the whole conveying device has a shock resistance; the upper area of the moving platform 3 is used for fixedly mounting the rotating speed reducer 1, the platform support 2, the turning sliding platform 5 and the horizontal speed reducer 6; the moving platform 3 is provided with a locking mechanism and / or a supporting mechanism, which can ensure that the position is fixed after being moved to the position.

[0097] A high-falling object impact protection conveying method, which adopts the above-mentioned high-falling object impact protection conveying device, comprises the following steps:

[0098] S1, by manual or automatic mode, transport the high-falling object impact protection conveying device to the position of receiving the high-falling articles 10, and adjust to the appropriate position, so as to ensure that the articles 10 falling from the high fixed position can fall to the end at a required angle; before starting work, the distance measuring instrument 7 is needed to judge the height of the outlet end of the falling object conveyor 9 to the receiving part 101 at this time, and the speed when reaching the top of the turning sliding platform 5 is calculated, and the whole rotating speed reducer 1 is driven to rotate to the speed;

[0099] ​S2, start working, first release the falling object 10 from the high place through other mechanism, and start falling, and make it fall to the receiving part 101 through the adjustment of the control system 4, at this time the control system 4 gets the speed of the falling object 10 when it falls to the receiving part 101 through the previous measurement and calculation, and sends the command to make the rotary speed reducer 1 rotate according to the speed, so that the falling object does not impact or bounce after falling to the receiving part 101, the cover 103 is also automatically buckled after the falling object falls to the receiving part 101, and the falling object 10 rotates with the receiving part in the rotation of the turning slide 5, and changes the vertical impact force into the horizontal movement force; the receiving part 101 and the cover 103 rotate to the tangent position of the turning slide 5 and the horizontal speed reducer 6 after grabbing the falling object;

[0100] Figure 4 The rightmost end of the receiving part 101 in the A area, that is, the position close to the left end of the cover 103, is the collection work range of the high falling object impact protection transmission device, when the falling object 10 falls to the A area, at this time the cover 103 is still in the open state, as shown in Figures 6-7 , when the falling object 10 falls in (the falling object is not shown in the figure), the cover 103 rotates and finally buckles, as shown in Figures 8-9 , to buckle the falling object 10 in the cover 103;

[0101] S3, when the falling object comes to the turning slide 5 area and runs to the horizontal speed reducer 6, the rotary speed reducer 1 continues to rotate upward to make the falling object leave the limit of the rotary speed reducer 1, due to inertia, the falling object will continue to move on the horizontal speed reducer 6, at this time the horizontal speed reducer keeps rotating at a certain speed to make the falling object 10 slowly stop on the horizontal speed reducer 6 under the action of friction, and the speed of the horizontal speed reducer 6 can be adjusted according to the need, and the falling object 10 is sent to the outlet end through the horizontal speed reducer 6 for unified arrangement and storage.

[0102] In the step S2, the control system 4 measures and calculates the falling speed of the falling object 10, including the following steps:

[0103] Let the range finder 7 be point A, the outlet end of the high falling object 10 be point C, the receiving part 101 at the horizontal position directly below the high falling object 10 be point D, and the speedometer 8 be point B, wherein point B and point D are at the same horizontal position, the straight line distance between point A and point C is L1, the horizontal distance between point A and point D is L2, the straight line distance between point A and point D is L3, the vertical distance between point A and point D is h1, and the acute angle between the AD straight line and the horizontal line where the BD is located is θ1; g is the acceleration of gravity, 9.8 m / s 2 ;

[0104] As shown in Figure 10 , from the above geometric relationship, we can get:

[0105] The angle between AD and CD is

[0106] From the right triangle relationship, we have:

[0107]

[0108] From the cosine law, we have:

[0109]

[0110] Since:

[0111]

[0112] We have:

[0113]

[0114] From the energy conservation, let the initial velocity of the article 10 from point C to point D be V0, and the velocity at point D be V1. We can get V1:

[0115]

[0116] From the following formula, we can get the time t when the article 10 falls vertically to the horizontal height at point D:

[0117]

[0118] Through the above calculation results, we get the velocity of the article 10 to point D, and then calculate the speed V of the rotary reducer 1 at point D that needs to be matched. D To reach V1±5%, and ensure that the article 10 falls to point D when the rotary reducer 1 just reaches point D, the calculation process includes the following steps:

[0119] Let the center of rotation of the rotary reducer 1 be point O, the receiving part 101 at the horizontal position directly below the high article 10 be point D, the rotary radius length of the rotary reducer 1 be L, and the rotational speed be n1.

[0120] As shown in Figure 11 , we have:

[0121] ω = 2πn

[0122]

[0123] v = ωr

[0124] Rotational speed of the rotary reducer 1:

[0125] ω1 = 2πn1

[0126] Speed of the receiving part 101 at point D:

[0127] V D= ω1L

[0128] V D = 2πn1L

[0129] According to the above calculation, the time for the article to fall to the horizontal height of D is:

[0130]

[0131] Since the rotary speed reducer 1 has four receiving parts 101, the following formula is obtained, that is, the law is as follows: Figure 12

[0132] (N is a positive integer)

[0133] Where T is the fixed rotation period of the rotary speed reducer 1:

[0134]

[0135] Therefore, under the condition that the initial falling height of the article 10 is unchanged, T can be kept unchanged, and the rotary speed reducer 1 can be kept rotating as needed to smoothly run, but the control system 4, the speed detector 8 and the distance detector 7 still need to be kept on to ensure real-time monitoring of the speed of the new falling article 10.

[0136] In the process of step S2, the falling speed of the article is monitored by the speed detector 8, and the data obtained by the transmission device S1 is the speed v1 of the article 10 when it falls to the contact position. At this time, the horizontal position of the speed detector 8 is just below the article, and the falling article 10 is monitored in real time, and the measured speed is v2. The real-time data v2 is used to calibrate the previous data v1. The rotation speed of the rotary speed reducer 1 is also corrected synchronously to ensure that the speed difference between the rotary speed reducer 1 and the article 10 falling to the receiving part 101 is within ±5% during the whole process.

[0137] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application are still within the scope of the technical solution of the present application.​
