Description

Technical Field

[0001] The present invention relates to the field of conveying equipment, in particular to a conveying and transferring device, a conveying system and a conveying and transferring method. Background Art

[0002] When it is necessary to transfer an article between two conveying lines with perpendicular conveying directions, a lifting and transferring conveyor is usually used to achieve this.

[0003] For example, the "Sorting Line Lifting and Transferring Roller Line" disclosed in the Chinese utility model patent with the authorized publication number CN217376267U is a typical lifting and transferring conveyor. It realizes the transfer of articles by the conveying surface of a chain elevator moving up and down on the conveying surface of a roller feeding line. Such a structure of the chain elevator not only requires a power source (motor) to drive the sprocket for conveying, but also requires an additional power source (cylinder or hydraulic cylinder or motor) and a guiding structure to achieve the stable lifting of the carrier. Such a structure is relatively complex and requires more power sources. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems existing in the prior art, and provide a conveying and transferring device, a conveying system and a conveying and transferring method.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A conveying and transferring device, including a roller conveyor, and a pushing and transferring mechanism is further arranged on the frame of the roller conveyor. The pushing and transferring mechanism includes a push rod assembly and a pushing driving assembly that drives the push rod assembly to reciprocate linearly in a direction perpendicular to the conveying direction of the roller conveyor. The push rod assembly extends from above the conveying rollers of the roller conveyor to below the conveying rollers and is connected to the pushing driving mechanism below the conveying rollers.

[0007] Preferably, in the conveying and transferring device, the push rod assembly includes two push rods located between the conveying rollers. The two push rods are fixed on a connecting piece located below the conveying rollers. The connecting piece is connected to the pushing driving assembly, and the upper ends of the two push rods are connected by rubber rollers.

[0008] Preferably, in the conveying and transferring device, the push rod assembly includes at least one push rod, the push rod is hinged to a connecting member located below the conveying roller, the connecting member is connected to the pushing drive assembly, a blocking block is provided on the connecting member, the push rod is connected to an elastic member that abuts against the blocking block, and when the push rod abuts against a position-fixed driving member during movement, it is driven to rotate around the connecting shaft connecting it to the connecting member, the axis of the connecting shaft extends along the conveying direction of the roller conveyor, and the abutting position of the driving member and the push rod is located below the connecting shaft.

[0009] Preferably, in the conveying and transferring device, the push rod includes a first section, a second section, a third section, and a fourth section that are connected in sequence from top to bottom. The first section and the second section form an obtuse angle, the third section is parallel to the first section, the third section and the fourth section form an obtuse angle and they are on the same side of the first section. The side of the third section that biases towards the first section abuts against the blocking block and they are in surface contact. One end of the elastic member is connected above the connecting shaft.

[0010] Preferably, in the conveying and transferring device, when the push rod abuts against the blocking block, the first section is perpendicular to the conveying surface of the roller conveyor.

[0011] Preferably, in the conveying and transferring device, a roller is rotatably provided at the lower end of the push rod.

[0012] Preferably, in the conveying and transferring device, there are two push rods, and their upper ends are connected by a roller. The axis of the roller is perpendicular to the axis of the conveying roller and rotatably connects the push rods.

[0013] Preferably, in the conveying and transferring device, the output side of the roller conveyor is connected to a non-powered roller conveyor line. The axis of the conveying roller of the non-powered roller conveyor line is perpendicular to the axis of the roller, and the pushing and transferring mechanism can push the articles on the conveying and transferring device to the outside of the non-powered roller conveyor line.

[0014] A conveying system includes the conveying and transferring device as described in any one of the above.

[0015] A conveying and transferring method includes the following steps:

[0016] Provide a conveying and transferring device, which includes a roller conveyor. A pushing and transferring mechanism is further arranged on the frame of the roller conveyor. The pushing and transferring mechanism includes a push rod assembly and a pushing driving assembly that drives the push rod assembly to reciprocate linearly in a direction perpendicular to the conveying direction of the roller conveyor. The push rod assembly extends from above the conveying rollers of the roller conveyor to below the conveying rollers and is connected to the pushing driving mechanism below the conveying rollers; the output side of the roller conveyor is connected to a non-powered roller conveyor line, and the axis of the conveying rollers of the non-powered roller conveyor line is perpendicular to the axis of the rollers. The pushing and transferring mechanism can push the articles on the conveying and transferring device to the outside of the non-powered roller conveyor line;

[0017] Connect the input end of the roller conveyor to a first conveyor line, and connect the output end of the non-powered roller conveyor line to a second conveyor line;

[0018] When the push rod assembly is on the side of the roller conveyor away from the non-powered roller conveyor line, convey the articles to the front of the push rod on the roller conveyor through the first conveyor line;

[0019] The pushing driving assembly is activated to drive the push rod assembly to push the articles onto the second conveyor line.

[0020] The advantages of the technical solution of the present invention are mainly reflected in:

[0021] The pushing and transferring mechanism of the present invention uses a single pushing driving assembly to drive the push rod assembly to reciprocate horizontally in a direction perpendicular to the conveying direction of the roller conveyor. The pusher can push the articles on the roller conveyor outside the roller conveyor. Such a structure only requires one power source to achieve effective transfer of the articles, with a simpler structure, fewer power sources, lower equipment costs and usage costs.

[0022] The structure of the present invention enables the push rod to be hinged to the connecting piece and the push rod and the driving piece cooperate, etc. When pushing the articles, the push rod can be driven to rotate by the driving piece, so that the upper end of the push rod moves to the outside of the roller conveyor, thus ensuring more stable conveyance of the box outside the conveyor. When the side of the roller conveyor is connected to the non-powered roller conveyor line and through the design of the underframe of the non-powered roller conveyor line and the frame of the roller conveyor, the push rod assembly can effectively move the articles on the roller conveyor to the outside of the output end of the non-powered roller conveyor line, without the need for manual pushing of the articles entering the non-powered roller conveyor line onto the downstream powered conveyor line. Such a structure is simpler.

[0023] The present invention designs the shape of the push rod, so that it can better cooperate with the spring and the blocking block, and keeps the first section of the push rod in a vertical state under normal conditions. This is beneficial to reducing the size of the roller conveyor as much as possible. At the same time, the push rod and the blocking block are in surface contact, which can protect the push rod and the blocking block to a certain extent, and improve the supporting force of the push rod to ensure that the push rod can push more stably.

[0024] The pushing drive assembly of the present invention enables the moving stroke of the pushing rod to be twice that of the moving part of the linear moving device. Therefore, a smaller-sized pushing drive assembly can be used to make the push rod have a larger moving stroke to meet the use requirement of pushing an item to the outside of the unpowered roller conveyor line.

[0035] The objectives, advantages and features of the present invention will be illustrated and explained by the following non-restrictive description of the preferred embodiments. These embodiments are only typical examples of applying the technical solutions of the present invention, and any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.

It is only for the convenience of description and simplification of the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0037] The following describes the conveying and transferring device disclosed by the present invention with reference to the drawings. As shown in the attached Figure 1 and attached Figure 2 figures, it includes a roller conveyor 100. The roller conveyor 100 can be various known feasible structures. In this embodiment, the roller conveyor 100 includes a frame 101. A group of equally high conveying rollers 102 are rotatably arranged on the frame 101 through bearings. The conveying rollers 102 are arranged at equal intervals and in parallel. The top surface of a group of the conveying rollers 102 is higher than the top of the frame 101. The first ends of a group of the conveying rollers 102 are connected by a transmission mechanism. The transmission mechanism can be a chain transmission mechanism composed of a sprocket 103 and a chain (not shown in the figure) or a synchronous belt transmission mechanism composed of a pulley and a conveyor belt. Any one of the conveying rollers 102 is connected to a driving motor 104 through the transmission mechanism connected to its first end. The driving motor 104 is arranged on the frame 101 and is located below the conveying rollers 102. The driving motor 104 is close to the input end or the output end of the roller conveyor 100.

[0038] As shown in the attached Figure 2 figure, a protective edge 105 is also arranged on the frame 101 and is located on the conveying rollers 102. The protective edge 105 covers the transmission mechanism connected to the first end of the conveying rollers 102. A blocking member 117 is also arranged on the frame 101 and is located above the conveying rollers 102 and at the output end of the roller conveyor 100.

[0039] As shown in the attached Figure 1 and attached Figure 2As shown, a push transfer mechanism 200 is further provided on the frame 101 of the roller conveyor 100. The push transfer mechanism 200 is located in the middle of the roller conveyor 100. The push transfer mechanism 200 includes a push rod assembly 201 and a push driving assembly 202 that drives the push rod assembly 201 to reciprocate linearly in a direction perpendicular to the conveying direction of the roller conveyor 100. The push rod assembly 201 extends from above the conveying rollers 102 of the roller conveyor 100 to below the conveying rollers 102 and is connected to the push driving mechanism below the conveying rollers.

[0040] In one embodiment, the push rod assembly 201 includes two push rods 203 located between the conveying rollers 102. The push rods 203 can be straight rods or L-shaped rods. When the push rods 203 are straight rods, the push rods 203 can be vertically arranged or inclined. When the push rods 203 are inclined, the push rods 203 are perpendicular to the conveying surface of the roller conveyor 100. When the push rods 203 are inclined, the upper ends of the push rods 203 are more biased towards the second end of the conveying rollers 102, and the lower ends of the push rods 203 are more biased towards the first end of the conveying rollers 102. The lower ends of the two push rods 203 are fixed to a connecting member 204, and the connecting member 204 is connected to the push driving assembly 202. The upper ends of the two push rods 203 are connected by rubber rollers. Preferably, the rubber rollers are rotatably arranged on the two push rods 203.

[0041] In another embodiment, as shown in the appendix Figure 3 As shown, the push rod assembly 201 includes at least one push rod 203. The push rod 203 is hinged to a connecting member 204, and the connecting member 204 is connected to the push driving assembly 202. A blocking block 205 is provided on the connecting member 204. The push rod 203 is connected to an elastic member 206 that abuts against the blocking block 205. When the push rod 203 abuts against a driving member 207 with a fixed position during movement, the push rod 203 is driven to rotate around a connecting shaft 208 connecting it to the connecting member 204. The axis of the connecting shaft 208 extends along the conveying direction of the roller conveyor. The abutting position of the driving member 207 and the push rod is located below the connecting shaft 208. The driving member 207 and the blocking block 205 are distributed on the left and right sides of the connecting shaft 208. Of course, in other embodiments, the blocking block 205 can also be provided below the connecting member 204. At this time, the blocking block abuts against the part of the push rod below the connecting shaft, and the blocking block and the driving member are on the same side of the push rod.

[0042] As shown in the appendix Figure 3As shown, there are two push rods 203, and the connecting member 204 is a flat plate. The two push rods 203 are hinged at both ends of the connecting member 204. The push rod 203 can be a straight rod or an L-shaped rod. Moreover, the length of the part of the push rod 203 above the connecting shaft 208 is much greater than the length of the part of the push rod 203 below the connecting shaft 208.

[0043] As shown in the attached Figure 3 figure, the push rod 203 includes a first section 209, a second section 210, a third section 211, and a fourth section 212 that are connected in sequence from top to bottom. The first section 209 extends from above the roller to below, and the first section 209 and the second section 210 form an obtuse angle. The second section 210 extends to the left. The included angle between the first section 209 and the second section 210 is between 130° and 140°. The length of the second section 210 is much less than the length of the first section 209. The third section 211 is parallel to the first section 209, and the length of the third section 211 is slightly less than the length of the second section 210. The third section 211 and the fourth section 212 form an obtuse angle and are on the same side of the first section 209. The included angle between the fourth section 212 and the third section 211 is slightly less than the included angle between the first section 209 and the second section 210, and the fourth section 212 extends to the left of the third section 211. Preferably, the included angle between the fourth section 212 and the third section 211 is between 110° and 120°. The side of the third section 211 that biases towards the first section 209 abuts against the blocking block 205 on its right side. The blocking block 205 is arranged on the top surface of the flat plate, and the side surface thereof facing the third section 211 is perpendicular to the axis of the conveying roller 102. The third section 211 abuts against the side surface of the blocking block 205, and the two are in surface contact. In this way, the push rod 203 can be better limited by the blocking block 205.

[0044] As shown in the attached Figure 4 figure, when the push rod 203 abuts against the blocking block 205, the first section 209 is perpendicular to the conveying surface of the roller conveyor 100. In this way, the horizontal space occupied by the push rod when it is at the first end of the conveying roller 102 can be minimized as much as possible, so that the width of the roller conveyor can be made smaller. Of course, in other embodiments, when the push rod 203 abuts against the blocking block, the first section 209 can also be inclined towards the second end of the conveying roller 102.

[0045] As shown in the attached Figure 3 and the attached Figure 4As shown, a first connecting pin 213 and a second connecting pin 214 are provided on the outer side of the push rod 203. The first connecting pin 213 is located at the junction of the first section 209 and the second section 210. The second connecting pin 214 is located at the end of the connecting member 204. The height of the second connecting pin 214 is equivalent to the height of the connecting shaft 208 and is located on the right side of the connecting shaft 208. The connecting shaft 208 is located at the junction of the third section 211 and the fourth section 212. The elastic member 206 is a spring, and one end of the spring is connected to the first connecting pin 213, and the second end of the spring is connected to the second connecting pin 214. At the same time, when the push rod 203 abuts against the blocking block 205, the extending direction of the spring is parallel or substantially parallel to the extending direction of the first section 209.

[0046] As shown in the appendix Figure 3 As shown, the two push rods 203 are connected by a connecting rod 215 located above the conveying roller 102. At the same time, their upper ends are connected by a roller 216. The axis of the roller 216 is perpendicular to the axis of the conveying roller 102 and rotatably connects the push rod 203. The lower end of the push rod 203 is rotatably provided with a roller 217.

[0047] As shown in the appendix Figure 5 As shown, in order to prevent the article from being blocked by the push rod 203 when being conveyed from the external conveying line to the roller conveyor 100 and thus unable to be effectively conveyed to the front of the push rod 203, the protective edge 105 includes guiding members 106 provided on both sides of the pushing and transferring mechanism 200. The two guiding members 106 are symmetrically arranged. One of the guiding members 106 is located at the input end of the roller conveyor 100, and the other guiding member 106 is located at the output end of the roller conveyor 100. The guiding member 106 includes a first guiding surface 107, a second guiding surface 108 and a third guiding surface 109 that are connected in sequence from the outside to the inside. The first guiding surface 107 forms an acute angle with the vertical plate 110 of the protective edge 105. The vertical plate 110 is perpendicular to the axis of the conveying roller 102. The first guiding surface 219 and the second guiding surface 108 form an obtuse angle. The second guiding surface 108 is perpendicular to the axis of the conveying roller 102. The third guiding surface 109 forms an obtuse angle with the first guiding surface 219 and is located on the second guiding surface 108. The third guiding surface 109 is connected to the vertical plate 110 through a connecting surface 111. The connecting surface 111 is perpendicular to the vertical plate 110. The diameter of the roller 216 is not less than the width of the connecting surface 111. When the first sections 209 of the two push rods 203 are located at the gap between the two connecting surfaces 111, the roller 216 does not protrude beyond the second guiding surface 108. Such a structure enables the box body to smoothly enter in front of the roller 216 to achieve smooth pushing.

[0048] As shown in the appendix Figure 6 As shown, a guiding plate 112 is further provided on the frame 101 above the conveying roller 102. The guiding plate 112 is located at the input end of the roller conveyor 100 and at the second end of the conveying roller 102. The guiding plate 112 includes a first plate member 113 and a second plate member 114 bent at an obtuse angle. The second plate member 114 is parallel to the second guiding surface 108. The first plate member 113 is closer to the input end of the roller conveyor 100 than the second plate member 114, and the second plate member 114 is inclined toward the output side of the roller conveyor 100 (the side where the second end of the conveying roller is located on the roller conveyor).

[0049] The pushing drive assembly 202 can be a linear movement device 218 capable of generating linear movement. For example, it can be a slide cylinder, a rodless cylinder, a servo linear module, etc. The push rod assembly is directly provided on the pushing drive assembly.

[0050] As shown in the appendix Figure 7 As shown, the pushing drive assembly 202 includes a linear movement device 218. The linear movement device 218 connects to and drives the moving member 219 to reciprocate linearly. The moving member 219 includes two intermediate connecting members 220. On both sides of the two intermediate connecting members 220, sliding plates 221 located on both sides of the linear movement device 218 are connected. The sliding plates 221 are slidably arranged on a second guide rail 222 provided on the frame 101. The extending direction of the second guide rail 222 is parallel to the axis of the conveying roller 102.

[0051] As shown in the appendix Figure 8 As shown, the moving member 219 is connected to a synchronous belt conveying mechanism 223. The synchronous belt conveying mechanism 223 includes two synchronous rollers 224 and a synchronous belt 225 sleeved on the two synchronous rollers 224. The axes of the synchronous rollers 224 are perpendicular to the axis of the conveying roller 102 and are rotatably arranged on wheel seats 226. The wheel seats 226 are arranged at both ends of the sliding plates 221. The synchronous belt 225 of the synchronous belt conveying mechanism 223 is connected to a connecting member of the push rod assembly 201 and a clamping member 227. The connecting member of the push rod assembly 201 is connected to the upper straight belt section 228 of the synchronous belt 225 through a clamping fixing member 231 at its bottom. The push rod assembly 201 is slidably arranged on a first guide rail 229 on the moving member 219. The first guide rail 229 has two and is arranged on the tops of the two sliding plates 221. The clamping member 227 is fixed on the lower straight belt section 230 of the synchronous belt 225. The position of the clamping member 227 is fixed. The clamping member 227 can be fixed on the frame 101 or other feasible positions.

[0052] When such a structure moves with the moving member 219, the synchronous belt conveying mechanism 223 moves simultaneously with the moving member 219, and the synchronous belt 225 can rotate. Therefore, the push rod assembly 201 can be driven by the synchronous belt 225, so that the moving stroke of the push rod assembly 201 can be greater than the moving stroke of the moving part of the linear moving device 218. This is beneficial to reducing the length of the entire pushing drive assembly 202.

[0053] Generally, the support rod where the second end of the conveying roller 102 is located is a single rod body, so that the push rod cannot move to the outside of the roller conveyor 100. As shown in the appendix Figure 1 As shown, in this embodiment, the support rod is multi-segmented, that is, the straight rod includes an intermediate rod 115 and end rods 116 disposed at both ends of the intermediate rod 115 with a gap therebetween. The gap between the end rod 116 and the intermediate rod 115 faces the push rod 203, so that the push rod 203 can move to the outside of the roller conveyor 100 from the gap between the end rod 116 and the intermediate rod 115.

[0054] As shown in the appendix Figure 6 As shown, the output side of the roller conveyor 100 is connected to the unpowered roller conveyor line 300. The axis of the conveying rollers of the unpowered roller conveyor line 300 is perpendicular to the axis of the rollers. The pushing and transferring mechanism 200 can push the articles on the conveying and transferring device to the outside of the unpowered roller conveyor line 300.

[0055] As shown in the appendix Figure 6 As shown, the unpowered roller conveyor line 300 includes a chassis 301. The conveying rollers are horizontally arranged on the chassis 301. The conveying rollers are divided into three groups, that is, the conveying rollers include an intermediate conveying roller group 302 and end conveying roller groups 303 disposed at both ends of the intermediate conveying roller group 302 with a gap therebetween. The intermediate conveying roller group is arranged on a first roller frame 305, and the intermediate conveying roller group 302 is arranged on a second roller frame 306. The first roller frame 305 and the second roller frame 306 are disposed on the chassis 301 with a gap therebetween, and the gap therebetween allows the push rod 203 to move through. The pushing drive assembly can drive the push rod 203 to move to the output end of the unpowered roller conveyor line 300. At the same time, a driving member 207 is arranged on the chassis 301, and the driving member 207 is close to the output end of the unpowered roller conveyor line. When the push rod 203 moves towards the unpowered roller conveyor line 300 until the roller 217 at its lower end abuts against the driving member 207, the push rod 203 rotates and drives the rollers 216 at the upper ends of the two push rods 203 to flip to the outside of the output end of the unpowered roller conveyor line 300. Thus, the rollers 216 push the box out of the unpowered roller conveyor line 300 and move it to the downstream conveyor line.

[0056] As shown in the attached Figure 6 figure, in order to prevent the box body from shifting in position on the unpowered roller conveyor line 216, two guiding baffles 304 are symmetrically arranged on the chassis 301 above the conveying rollers. The guiding baffle 304 close to the guiding plate 112 is connected to the second plate member 114 of the guiding plate 112. When the box body abuts against the blocking member 117, the box body is located between the two guiding baffles 304.

[0057] Embodiment 2

[0058] This embodiment discloses a conveying system, as shown in the attached Figure 10 figure, which includes the conveying and transferring device of the above embodiment. The input end of the roller conveyor 100 is connected to a first conveyor line 400, and the output end of the unpowered roller conveyor line 300 is connected to a second conveyor line 500. Before the box body 600 is conveyed onto the roller conveyor 100, the first section of the push rod 203 is located at the first end of the conveying roller and at the gap between the two guiding members 106. At this time, when the input conveyor line conveys an article to the middle position of the roller conveyor 100, the linear moving device 218 starts to drive the two push rods 203 to move towards the unpowered roller conveyor line 300, and moves the box body from the roller conveyor onto the unpowered roller conveyor line 300 and through the roller conveyor to the first conveyor line 400.

[0059] When the entire system is working, the automatic operation of each mechanism can be controlled by the control device in combination with sensors at specific positions. The corresponding control technology is a known technology and will not be elaborated here.

[0060] There are still many implementation manners of the present invention. All technical solutions formed by using equivalent transformations or equivalent substitutions fall within the protection scope of the present invention.
