Description

TECHNICAL FIELD

[0001] The present application relates to the field of logistics sorting, in particular to a stack separating device. BACKGROUND

[0002] The logistics sorting industry is an indispensable part of the modern logistics system, which undertakes the task of classifying and transporting a large number of objects quickly and accurately to the designated location. With the rapid development of e-commerce, the logistics industry is facing more and more object sorting demands.

[0003] At present, the logistics sorting industry generally uses stack separating equipment to separate and space the stacked objects, so that subsequent automated equipment can accurately identify and sort. Such equipment is usually composed of multiple sections of conveyor belts with fixed inclination angles, which use slope to achieve object separation and spacing adjustment. However, the existing stack separating equipment usually adopts a fixed inclination angle design, which often requires a larger inclination angle to achieve effective separation for light objects. However, the existing equipment cannot be adjusted flexibly due to the fixed inclination angle, resulting in poor separation effect for light objects. If the inclination angle is increased to accommodate light objects, heavy objects may slip or have difficulty climbing the slope due to the large slope, affecting overall sorting efficiency. SUMMARY

[0004] The purpose of the present application is to solve the technical problems of low separation efficiency and poor adaptability caused by the fixed inclination angle of the conveying mechanism of the existing stack separating equipment. The present application provides a stack separating device that can adjust the speed and inclination angle of the conveyor belt of different conveying mechanisms to separate objects of different weights and sizes.

[0005] To solve the above technical problems, an embodiment of the present application discloses a stack separating device, which comprises a first conveying mechanism, a second conveying mechanism and a third conveying mechanism arranged in sequence; the first conveying mechanism comprises a first horizontal conveying surface and a first driving assembly for driving the first horizontal conveying surface to rotate; the second conveying mechanism comprises at least one inclined conveying surface, a second driving assembly and a third driving assembly for driving the inclined conveying surface to rotate, wherein the height of the starting end of the inclined conveying surface is lower than the height of the end of the first horizontal conveying surface in the vertical direction, and the height of the end of the inclined conveying surface is higher than the height of the end of the first horizontal conveying surface, and the first horizontal conveying surface is used for conveying articles to the inclined conveying surface; the third conveying mechanism comprises a second horizontal conveying surface and a fourth driving assembly for driving the second horizontal conveying surface to rotate, wherein the height of the starting end of the second horizontal conveying surface is lower than or equal to the height of the end of the inclined conveying surface in the vertical direction, and the inclined conveying surface is used for conveying articles to the second horizontal conveying surface; the conveying speed of the first horizontal conveying surface is less than the conveying speed of the inclined conveying surface, and the conveying speed of the inclined conveying surface is less than or equal to the conveying speed of the second horizontal conveying surface.

[0006] The above technical solution can construct a stack separating device with a height difference. When the articles are conveyed from the first horizontal conveying surface to the inclined conveying surface, the height difference between the end of the first horizontal conveying surface and the starting end of the inclined conveying surface causes the articles to flip or vibrate during the conveying process, so that the stacked articles fall on the first horizontal conveying surface or the inclined conveying surface, thereby realizing the separation of the stack. Moreover, the different speeds between the conveying surfaces can also realize the separation of the stack. For example, the conveying speed of the first horizontal conveying surface is the smallest, the conveying speed of the inclined conveying surface is greater than the conveying speed of the first horizontal conveying surface, and the conveying speed of the second horizontal conveying surface is greater than or equal to the conveying speed of the inclined conveying surface. In this way, when the articles stacked above and below are conveyed to the adjacent two conveying surfaces, the lower articles first contact the inclined conveying surface to increase the moving speed, and under the action of inertia, the upper articles are thrown out, thereby realizing the separation of the stack. In this way, the height difference between the conveying surfaces can be used to realize the separation of the stack, and the speed difference can also be used to realize the separation of the stack.

In the vertical direction, the height of the starting end of the inclined conveying surface 200 is lower than the height of the end of the first horizontal conveying surface 100, and the height of the end of the inclined conveying surface 200 is higher than the height of the end of the first horizontal conveying surface 100. The first horizontal conveying surface 100 is used to convey articles to the inclined conveying surface 200. The third conveying mechanism 30 comprises a second horizontal conveying surface 300 and a fourth driving assembly 302, the fourth driving assembly 302 is used to drive the second horizontal conveying surface 300 to rotate. In the vertical direction, the height of the starting end of the second horizontal conveying surface 300 is lower than or equal to the height of the end of the inclined conveying surface 200. The inclined conveying surface 200 is used to convey articles to the second horizontal conveying surface 300. The conveying speed of the first horizontal conveying surface 100 is less than the conveying speed of the inclined conveying surface 200, and the conveying speed of the inclined conveying surface 200 is less than or equal to the conveying speed of the second horizontal conveying surface 300.

[0071] Reference FIG. 1A , FIG. 1B and FIG. 1C , the application mainly combines the first conveying mechanism 10, the second conveying mechanism 20 and the third conveying mechanism 30 to construct a stack separating device with height difference. Wherein, as FIG. 1CAs shown, three stacked objects are conveyed to the first horizontal conveying surface 100 of the first conveying mechanism 10, the first driving motor 10203 drives the first driving roller 10201 to rotate and drives the first conveying belt 10200 to rotate with the first driven roller 10202, the conveying surface of the rotating first conveying belt 10200 is the first horizontal conveying surface 100. The objects are conveyed to the inclined conveying surface 200 of the second conveying mechanism 20, the second driving motor 20203 and the third driving motor 20303 respectively drive the second driving roller 20201 and the third driving roller 20301 to rotate, and drive the second conveying belt 20200 and the third conveying belt 20300 to rotate in turn with the second driven roller 20202 and the third driven roller 20302, the conveying surfaces of the rotating second conveying belt 20200 and the third conveying belt 20300 together form the inclined conveying surface 200. Because there is a height difference between the end of the first horizontal conveying surface 100 and the starting end of the inclined conveying surface 200, the height difference will cause the upper objects to overturn or vibrate during the conveying process to the inclined conveying surface 200, so that the upper objects fall on the first horizontal conveying surface 100 or the inclined conveying surface 200, thereby preliminarily separating the stacked objects vertically; then, after the stacked objects pass through multiple inclined conveying surfaces 200, the distance between the objects gradually increases, achieving separation in the direction of the conveying surface; finally, the separated objects are conveyed from the inclined conveying surface 200 to the second horizontal conveying surface 300 of the third conveying mechanism 30, the fourth driving motor 30203 drives the fourth driving roller 30201 to rotate, and drives the fourth conveying belt 30200 to rotate with the fourth driven roller 30202, the conveying surface of the rotating fourth conveying belt 30200 is the second horizontal conveying surface 300. The second horizontal conveying surface 300 sends out the three separated objects, achieving the final sorting of the objects. Of course, the different speeds between the conveying surfaces can also achieve the separation of the stacked objects, for example, the first driving motor 10203 drives the first conveying belt 10200 to make the first horizontal conveying surface 100 run at a conveying speed V1 of 1 m / s, which plays a role in collecting objects and buffering; the second driving motor 20203 and the third driving motor 20303 respectively drive the second conveying belt 20200 and the third conveying belt 20300, so that the conveying speed V2 of the inclined conveying surface 200 is 2 m / s, which is greater than the conveying speed of the first horizontal conveying surface 100, when the stacked objects are conveyed from the first horizontal conveying surface 100 to the inclined conveying surface 200, the lower objects first contact the high-speed running inclined conveying surface 200 and accelerate forward, the upper objects lag due to inertia, thereby separating from the lower objects under the action of the acceleration difference; further, the fourth driving motor 30203 drives the fourth conveying belt 30200 to rotate, so that the conveying speed V3 of the second horizontal conveying surface 300 is 2.5 m / s, which is greater than the speed of the inclined conveying surface 200, which continues to convey and enlarge the distance between the separated objects, achieving the separation of the stacked objects.In this way, the separation of the stack can be achieved not only by the height difference between the conveying surfaces, but also by the speed difference between the conveying mechanisms.

[0072] It should be noted that the number of the inclined conveying surfaces 200 and the second driving assemblies 202 of the second conveying mechanism can be selected as needed. In the embodiment, the second conveying mechanism includes four inclined conveying surfaces 200 and four second driving assemblies 202, which are sequentially arranged and gradually increase in height. Such an arrangement prolongs the overall separation distance of the objects, so that the objects need to experience multiple continuous climbing and acceleration during the conveying process, thereby providing more opportunities for the objects to slide and the spacing to be pulled apart, and improving the separation effect of the stack. Of course, in other embodiments, the number of the inclined conveying surfaces 200 and the second driving assemblies 202 can also be one, two, three, etc., which are not limited here.

[0073] In some possible embodiments, the first conveying mechanism 10 further includes a first side baffle 101, which is arranged on both sides of the first conveying mechanism 10. Such an arrangement continuously limits the lateral movement of the objects during the conveying process of the first horizontal conveying surface 100, prevents the objects from deviating from the first horizontal conveying surface 100, thereby keeping the objects moving stably along the predetermined path and reducing the conveying interruption or loss of objects caused by deviation or falling.

[0074] For example, the first side baffle 101 of the present application includes a first guard plate 106. The first guard plate 106 is arranged at the rear end of the first side baffle 101, which is used to block the objects from being stuck or falling into the gap between the first side baffle 101 and the second side baffle 201, thereby preventing the objects and the conveying mechanism from being damaged. In some possible embodiments, the first conveying mechanism 10 further includes a first brush baffle 103, a first base frame 104, and a first rack 105. Referring to FIG. 3A and FIG. 3B In the vertical direction, the first base frame 104 is arranged above the first rack 105, and the first horizontal conveying surface 100 is arranged above the first base frame 104. The first rack 105 is provided with a first vertical rod 1050 and a second vertical rod 1051 for supporting the first base frame 104 arranged on the first rack 105. Referring to FIG. 2A and FIG. 3A, a first gap 107 is formed between the first driving assembly 102 and the second driving assembly 202. The first brush baffle 103 is arranged at the rear end of the first base frame 104, and the first brush baffle 103 comprises a first brush plate support 1030 and a first brush plate 1031. The first brush plate 1031 is provided with a first waist hole 1032, and the first brush plate support 1030 is connected with the rear end of the first base frame 104. The first brush plate 1031 is connected with the first brush plate support 1030 through the first waist hole 1032. The first brush plate 1031 slides up and down along the vertical direction through the first waist hole 1032. Through the sliding fit of the first waist hole 1032 and the first brush plate support 1030, the first brush plate 1031 can adjust the position in the vertical direction, so as to adjust the brush height of the first brush baffle 103, thereby sealing the first gap 107 formed between the end of the first horizontal conveying surface 100 and the starting end of the inclined conveying surface 200 due to the height difference, and preventing the articles from sliding or being clamped at the joint of the mechanism.

[0075] With reference to FIG. 4A , FIG. 4B and FIG. 5 , the first driving assembly 102 of the present application comprises a first conveying belt 10200, a first driving roller 10201, a first driven roller 10202, a first driving motor 10203, and first and second support side plates 10205 and 10206 arranged on both sides of the first horizontal conveying surface 100.

When the first driving motor transmission shaft 102030 rotates, the first synchronous pulley 10207 connected with it rotates; the first synchronous pulley 10207 transmits the rotary motion to the second synchronous pulley 10208 through the first synchronous belt 10209; the second synchronous pulley 10208 drives the first driving roller transmission shaft 102010 to rotate, thereby driving the first driving roller 10201 to rotate; through the friction between the first conveying belt 10200 and the roller, the first driven roller 10202 rotates; finally, the first conveying belt 10200 is driven by the first driving roller 10201 and the first driven roller 10202 to move horizontally, conveying the objects placed on the first horizontal conveying surface 100 from the starting end to the end, and transferring to the inclined conveying surface 200. Through such arrangement, the first support side plate 10205 and the second support side plate 10206 of the first horizontal conveying surface 100 provide installation support and positioning for the first driving roller 10201, the first driven roller 10202 and the first driving motor 10203; at the same time, the first driving motor 10203 drives the first conveying belt 10200 to rotate, which can convey the objects placed thereon from the starting end to the end, and further transfer to the inclined conveying surface 200, ensuring the smooth operation of the objects during conveying.

[0076] In some possible embodiments, the first driving assembly 102 further comprises a first roller adjusting assembly 10218, a first guide wheel adjusting assembly 10221. The first roller adjusting assembly 10218 is arranged at the left and / or right side of the first roller mounting hole 10220 for placing the first driven roller drive shaft 102020 in the first support side plate 10205 and the second support side plate 10206. The first roller stopper 10219 is placed at the left and / or right side of the first mounting hole for preventing the first driven roller drive shaft 102020 from disengaging from the mounting position during adjustment or operation. The first roller adjusting assembly 10218 comprises a first nut plate 102180 and a first adjusting rod 102181 placed in the first nut plate 102180. By rotating the first adjusting rod 102181, the axial position of the first driven roller drive shaft 102020 in the first roller mounting hole 10220 can be pushed, so as to adjust the relative distance between the first driving roller 10201 and the first driven roller 10202, to achieve the adjustment of the tension of the first driving roller 10201, the first driven roller 10202 and the end of the first conveying belt 10200. The first guide wheel adjusting assembly 10221 is arranged below the first roller adjusting assembly 10218 in the vertical direction, and the first guide wheel adjusting assembly 10221 comprises a first guide wheel mounting seat 102212, a first guide wheel adjusting plate 102211 and a first guide wheel 102210 placed on the first guide wheel adjusting plate 102211. The first guide wheel adjusting plate 102211 is arranged at the upper side of the first guide wheel mounting seat 102212 in the vertical direction, and the first guide wheel 102210 is arranged on the first guide wheel adjusting plate 102211.

[0077] Further, the first driving assembly 102 of the present application further comprises a first protective cover 10214, a second protective cover 10215, a third protective cover 10216 and a fourth protective cover 10217. It is continued to refer to FIG. 4A and FIG. 4BThe first protective cover 10214 and the second protective cover 10215 are arranged on the first support side plate 10205 and connected with the first support side plate 10205 through the first protective cover support 10210 and the second protective cover support 10211. The third protective cover 10216 and the fourth protective cover 10217 are arranged on the second support side plate 10206 and connected with the second support side plate 10206 through the third protective cover support 10212 and the fourth protective cover support 10213.

[0078] In some possible embodiments, the second conveying mechanism 20 further comprises second side plates 201 arranged on both sides of the first conveying mechanism 10. In this way, the lateral movement of the articles can be continuously limited during the conveying process of the inclined conveying surface 200, the articles can be prevented from being separated from the inclined conveying surface 200, and the articles can be kept to move stably along the predetermined path, so as to reduce the conveying interruption or article loss caused by deviation or falling.

[0079] For example, the second side plate 201 of the present application comprises a second guard plate 209. Referring to FIG. 1A and FIG. 1B , the second guard plate 209 is arranged at the rear end of the second side plate 201. The second guard plate 209 is used to block the articles from being stuck or falling into the gap between the second side plates 201 and / or the third side plate 301, so as to prevent the articles and the conveying mechanism from being damaged.

[0080] It should be noted that the combination of the second side plate 201 and the second guard plate 209 of the present application makes the second side plates 201 stacked with each other to form a structure similar to fish scales. When the angle of the inclined conveying surface 200 changes, the gap that increases or changes due to the change of the angle can be covered by the relative displacement between the second side plates 201, so as to prevent the articles from entering or being stuck in the gap.

[0081] In some possible embodiments, the second conveying mechanism further comprises a second brush plate 204, a second base frame 205 and a second rack 206. Referring to FIG. 2B , FIG. 6A and FIG. 6B , in the vertical direction, the second base frame 205 is arranged above the second rack 206, and the inclined conveying surface 200 is arranged above the second base frame 205. Referring to FIG. 2B and FIG. 6B, a second gap 210 exists between the second driving assembly 202 and the third driving assembly 203, wherein a second brush baffle is arranged at the rear end of the second base frame 205, the second brush baffle comprising a second brush baffle support 2040 and a second brush baffle plate 2041, the second brush baffle plate 2041 being provided with a second waist hole 2042, the second brush baffle support 2040 being connected with the rear end of the second base frame 205, and the second brush baffle plate 2041 being connected with the second brush baffle support 2040 through the second waist hole 2042. The second brush baffle plate 2041 slides up and down along the vertical direction through the second waist hole 2042. Through the sliding fit of the second waist hole 2042 and the second brush baffle support 2040, the second brush baffle plate 2041 can be adjusted in position in the vertical direction, so as to adjust the brush height of the second brush baffle 204, thereby sealing the gap formed between the starting end and the ending end of the inclined conveying surface 200 due to the height difference, or the second gap 210 between the ending end of the inclined conveying surface 200 and the starting end of the second horizontal conveying surface 300 due to the height difference, so as to prevent the articles from sliding or being clamped at the joint of the mechanism.

[0082] With reference to FIGS. 6A-6C , the second rack 206 is provided with a third vertical rod 2060 at the front end of the second base frame 205, and is provided with a fourth vertical rod 2061 at the rear end of the second base frame 205, the height of the third vertical rod 2060 being lower than the height of the fourth vertical rod 2061. The third vertical rod 2060 is provided with a first rotary connecting piece 207, and the fourth vertical rod 2061 is provided with a first jacking assembly 208. The first jacking assembly 208 is used to lift the rear end of the second base frame 205. When the first jacking assembly 208 is operated, it lifts or lowers the rear end of the second base frame 205, so that the second base frame 205 rotates about the first rotary connecting piece 207 as the fulcrum, thereby directly changing the inclination angle of the inclined conveying surface 200 arranged on the second base frame 205. Through the adjustment of the first jacking assembly 208, the inclination angle of the inclined conveying surface 200 can be made smaller to facilitate the heavy articles to overcome the friction force and stably climb the slope, or the inclination angle of the inclined conveying surface 200 can be made larger to promote the effective separation of the lightweight articles stacked up and down.

[0083] Exemplarily, with reference to FIG. 7The first rotary connecting member 207 comprises a first hinged seat 2070, a first pin shaft 2072, a first mounting seat 2073 and a first rubber pad 2075. The first hinged seat 2070 is arranged on the third vertical rod 2060 and is provided with a first hinged seat pin hole 2071. The first mounting seat 2073 is arranged on the first rubber pad 2075 and is provided with a first mounting hole 2074. The first pin shaft 2072 is inserted into the first hinged seat pin hole 2071 and the first mounting hole 2074, and the first rubber pad 2075 is arranged below the front end of the second base frame 205 in the vertical direction. In this way, the first hinged seat 2070 arranged on the third vertical rod 2060 is connected with the first mounting seat 2073 arranged on the first rubber pad 2075 by inserting the first pin shaft 2072 into the first hinged seat pin hole 2071 and the first mounting hole 2074, so as to form a rotatable fulcrum below the front end of the second base frame 205. This structure allows the second base frame 205 to rotate with the first pin shaft 2072 as the fulcrum, and the first rubber pad 2075 can buffer the vibration and impact generated during rotation.

[0084] For example, referring to FIG. 8 The first jacking assembly 208 comprises a first fish-eye screw 2080, a first pin 2083 and a second rubber pad 2084. The first fish-eye screw 2080 comprises a first fish-eye screw pin hole 2081 and a first fish-eye screw threaded rod 2082. The first fish-eye screw threaded rod 2082 is connected with the fourth vertical rod 2061. By twisting the first fish-eye screw threaded rod 2082, the first fish-eye screw 2080 can be driven to elongate or contract relative to the fourth vertical rod 2061. It should be noted that the first fish-eye screw threaded rod 2082 can also be connected with the fourth vertical rod 2061 through a nut or other connecting assembly to achieve the elongation or contraction of the first fish-eye screw. The first pin 2083 is inserted into the first fish-eye screw pin hole 2081, and the two ends of the first pin 2083 are connected with the second rubber pad 2084, which is arranged below the rear end of the second base frame 205 in the vertical direction. In this way, by rotating the first fish-eye screw 2080, the first fish-eye screw threaded rod 2082 is screwed into or out of the fourth vertical rod 2061, so as to change the extension length of the first fish-eye screw 2080 from the fourth vertical rod 2061, thereby jacking up or lowering the rear end of the second base frame 205 arranged above the fourth vertical rod 2061. At the same time, the first pin 2083 inserted into the first fish-eye screw pin hole 2081 transmits the jacking force to the second rubber pad 2084, so that the second rubber pad 2084 is always in contact with the bottom surface of the second base frame 205 to buffer the local contact stress.

[0085] In some possible embodiments, the angle range of the rotation of the inclined conveying surface 200 of the present application is 18-25°. Among them, for light objects less than or equal to 1.5 kg, the rotation angle range of the inclined conveying surface 200 is 22°-25°, and for heavy objects greater than 1.5 kg, the rotation angle range of the inclined conveying surface 200 is 18°-20°. Exemplarily, for light objects, the weight of the objects is selected to be 0.6 kg, 0.8 kg, 1.0 kg, 1.2 kg and 1.5 kg, and the rotation angle of the inclined conveying surface 200 is set to be 22°, 23° and 25°. A larger inclination angle provides sufficient gravitational component for light objects to overcome the friction with other objects, so that the light objects on the upper layer can be separated and fall on the conveying belt and be continuously conveyed. When the rotation angle is 21°, the inclination angle is insufficient, and the light objects cannot overcome the friction with other objects, resulting in that the light objects are easily stacked or only partially separated. For heavy objects, the weight of the objects is selected to be 1.6 kg, 1.7 kg, 1.9 kg, 2.1 kg and 2.3 kg, and the rotation angle of the inclined conveying surface 200 is set to be 18°, 19° and 20°. The stacked objects can be separated while avoiding too steep slope, so that the heavy objects move smoothly without violent sliding. The stacked objects can be separated, and when the rotation angle is 21°, the inclination angle is slightly larger, resulting in that the heavy objects accelerate to slide down the inclined conveying surface and are difficult to control, and collisions between objects easily occur, causing damage to the objects.

In this way, the third support side plate 20205 and the fourth support side plate 20206 on both sides of the second conveying belt 20200 provide installation support and positioning for the second driving roller 20201, the second driven roller 20202 and the second driving motor 20203.
