Description

Technical Field

[0001] The present invention belongs to the technical field of logistics and transportation, and specifically relates to an unmanned intelligent transportation device and an operation method for cargo transfer. Background Art

[0002] With the continuous development and maturity of unmanned driving technology, unmanned driving indoors and outdoors in closed parks has begun to show great application potential in the field of logistics and transportation. Currently, there are unmanned transportation equipment on the market that can cooperate with production lines to transfer goods, can work uninterruptedly 24 hours a day, and save human resources.

[0003] In the prior art, when using intelligent unmanned transport vehicles to connect materials on the production line, the following problems exist: when the materials move through the production line and enter the transport vehicle, they have forward kinetic energy. In order to facilitate the entry of materials, the transport vehicle will be equipped with rollers to receive the materials, and the blocking friction is relatively small. If the other side of the transport vehicle is in an open state, the forward kinetic energy of the materials is prone to fall off due to the inability to block the brake, resulting in damage to the materials; and some transport vehicles will also be equipped with a rolling shutter door made of flexible material at the opening for sealing. At this time, when the materials enter the transport vehicle, the materials will rigidly collide with the unopened rolling shutter door on one side of the transport vehicle for braking. Because the rolling shutter door is made of flexible material, after the rigid collision between the materials and the rolling shutter door, it is easy to affect the subsequent opening of the rolling shutter door, and it is also easy to cause the rolling shutter door to be damaged.

[0004] To this end, the present invention provides an unmanned intelligent transportation device and an operation method for cargo transshipment. Summary of the invention

[0015] An operating method of an unmanned intelligent transport device for cargo transfer, the method is as follows:

[0016] S1: When feeding, the height of the sliding box is adjusted by the first hydraulic cylinder, so as to adjust the top positions of the first roller and the second roller to be slightly lower than the production line height. At this time, the material flows down from the production line and then is fed through the opening on one side of the placement chamber;

[0017] S2: When the material enters from the opening on one side of the placement chamber, the lead screw at the opening on the other side of the placement chamber rotates through the power part, thereby driving a pair of rack plates to move toward each other. Through the meshing of the rack plates and the teeth, the rotating column rotates, and the blocking rod on the rotating column rotates to block the opening on the other side of the placement chamber to block the material. After the material completely enters the placement chamber, the power part will be closed at a delayed time, and then the rotating column will rotate under the action of the torsion spring force, so that the blocking rod and the rack plate are restored to their original positions, and the feeding is completed;

[0018] S3: After feeding, the sliding box is lowered by the first hydraulic cylinder, so that the top ends of the first roller and the second roller are lower than the opening bottom surface of the placement chamber;

[0019] S4: When discharging, the rolling door opens, and the sliding box is raised as a whole by the first hydraulic cylinder to make it slightly higher than the production line height. Then the power part drives the first roller or the second roller to rotate and discharge the material. At the same time, when the power part rotates, the baffle bar away from the material outlet position will open again. This is to prevent the material from flowing back. Then, after the discharging is completed, the baffle bar returns to its original position, and the discharging is completed.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The unmanned intelligent transport equipment and operation method for cargo transshipment described in the present invention can utilize the baffle rod to effectively brake the forward potential energy of the material when the material is fed, through the baffle rod, rotating column and other parts and structures. At the same time, the baffle rod will not occupy the vehicle body placement cavity space and external space, effectively avoiding the situation where the rolling door is damaged or the material is detached.

[0022] 2. The unmanned intelligent transportation equipment and operation method for cargo transshipment described in the present invention, when the material is placed in the placement cavity for transportation, in order to avoid the shaking of the material, after the material enters above a group of first rollers and a second roller, the first hydraulic cylinder will drive the sliding box to descend, and the bottom end of the sliding box will fit on the bottom end of the first slide groove, and at the same time, the annular airbag is squeezed by the pushing member to expand the annular rubber ring, so that the annular rubber ring bulges out of the first annular groove, and then fits with the bottom surface of the material to increase friction and play a stabilizing role; at the same time, when the material is discharged and fed, the first hydraulic cylinder will drive the sliding box to move upward, and the pushing member will be released, and the annular rubber ring will shrink, which will not affect the discharge and feeding operations of the material.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 13As shown, an unmanned intelligent transport device for cargo transfer described in an embodiment of the present invention includes a vehicle body 1; a placement cavity 11 is provided in the vehicle body 1, and both sides of the placement cavity 11 are in an open state; first slide grooves 12 are provided on both inner walls of the placement cavity 11; a pair of first slide grooves 12 are slidably connected with a sliding box 13, and a group of first rollers 15 and a group of second rollers 16 are rotatably connected between the opposite surfaces of the pair of sliding boxes 13, and the first rollers 15 and the second rollers 16 are staggered, and the number of both is an even number; the inner top walls of the pair of first slide grooves 12 are fixedly connected with a first hydraulic cylinder 14, and the first hydraulic cylinder 14 is The hydraulic rods are fixedly connected to the top ends of the adjacent sliding boxes 13 respectively; a pair of symmetrically distributed connecting blocks 2 are fixedly connected between the pair of sliding boxes 13, and the pair of connecting blocks 2 are respectively close to the two sides of the sliding boxes 13; a pair of symmetrically distributed second slide grooves 23 are opened on the relatively far sides of the pair of connecting blocks 2; a rack plate 24 is slidably connected in the second slide groove 23; a pair of symmetrically distributed rotating columns 21 are rotatably connected to the side walls of the connecting blocks 2, a torsion spring is installed at the connection between the rotating columns 21 and the connecting blocks 2, and a group of teeth 22 are fixedly connected to the outer wall of the rotating column 21, the rack plate 24 is located below the teeth 22, and the rotating column 21 is connected to the teeth 22 and the teeth 24. The strips 24 mesh with each other; a pair of sliding boxes 13 are rotatably connected with a pair of lead screws 25, and the lead screws 25 are provided with bidirectional threads; a pair of rack plates 24 on one side of the connecting block 2 are connected to the adjacent lead screws 25 through a lead screw nut pair; a power piece is provided in the sliding box 13, and the power piece drives the lead screw 25 to rotate; a baffle 26 is fixedly connected to the rotating column 21, and a rubber block 27 is fixedly connected to the side wall of the baffle 26; a rolling door is provided in the top of the vehicle body 1 at an opening position relative to the placement cavity 11; in the prior art, when using an intelligent unmanned transport vehicle to connect materials on the production line, the following problems exist: when the materials move through the production line and enter the transport vehicle When the material enters the transport vehicle, it has forward kinetic energy. In order to facilitate the entry of materials, the transport vehicle will be equipped with rollers to receive the materials. The blocking friction is small. If the other side of the transport vehicle is in an open state, the forward kinetic energy of the materials is easy to fall off due to the inability to block the brake, resulting in material damage. Some transport vehicles will also have a rolling door made of flexible material at the opening for sealing. At this time, when the material enters the transport vehicle, the material will rigidly collide with the unopened rolling door on one side of the transport vehicle for braking. Because the rolling door is made of flexible material, after the rigid collision between the material and the rolling door, it is easy to affect the subsequent opening of the rolling door, and it is also easy to cause the rolling door to be damaged.When the present invention is working, the setting of the rolling door (not shown) is the prior art. When the vehicle body 1 is feeding and unloading, the rolling door is in an open state. It is only in a closed state during transportation. The specific structure is not described. When feeding, the height of the sliding box 13 is first adjusted by the first hydraulic cylinder 14, so as to adjust the top position of the first roller 15 and the second roller 16 to be slightly lower than the production line height. At this time, the material flows down from the production line and then feeds through the opening on one side of the placement chamber 11. At this time, the first roller 15 and the second roller 16 are both in a non-braking state. , which can facilitate the entry of materials. When the materials enter from the opening on one side of the placement chamber 11, the lead screw 25 located at the opening on the other side of the placement chamber 11 is rotated by the power member, thereby driving a pair of rack plates 24 to move toward each other. Through the meshing of the rack plates 24 and the teeth 22, the rotating column 21 is rotated, and the blocking rod 26 located on the rotating column 21 is rotated to block the opening on the other side of the placement chamber 11 to block and brake the materials. The rubber block 27 on the side wall of the blocking rod 26 can reduce the rigid collision. At the same time, the blocking rod 26 can be limited. When the materials completely enter the placement chamber, After the cavity 11 is released, the power piece will be delayed to close (existing technology), and then the rotating column 21 will rotate under the action of the torsion spring force, so that the blocking rod 26 and the rack plate 24 will return to their original positions, and the feeding is completed. At the same time, the sliding box 13 is lowered by the first hydraulic cylinder 14, so that the top of the first roller 15 and the second roller 16 are lower than the bottom surface of the opening where the cavity 11 is placed; when discharging, the rolling door is opened, and the sliding box 13 is driven to rise as a whole by the first hydraulic cylinder 14, so that its bottom is slightly higher than the height of the production line, and then the first roller 15 or the second roller 16 is driven to rotate by the power piece. When the material is unloaded, the blocking rod 26 far away from the material outlet position will be opened when the power part rotates. This is to prevent the material from flowing back. After the material is unloaded, the blocking rod 26 returns to its original position, that is, the material is unloaded. Through the above operation, the blocking rod 26 can be used to effectively brake the forward potential energy of the material when the material is fed. At the same time, the blocking rod 26 will not occupy the space between the vehicle body 1 and the placement cavity 11 and the external space, effectively avoiding the situation where the rolling door is damaged or the material is separated (the adjustment of the first hydraulic cylinder 14 is processed by the distance sensor). ;

[0040] The power part includes a first motor 3; a pair of sliding boxes 13 are fixedly connected with the first motor 3, and the pair of first motors 3 are respectively arranged at the inner side walls of the pair of sliding boxes 13 away from each other; the output end of the first motor 3 is fixedly connected with a first rotating shaft 31; the first roller 15 and the second roller 16 are fixedly connected with the second rotating shaft 32 at both ends, and the second rotating shaft 32 extends into the sliding box 13; a group of first rollers 15 and a second roller 16 are fixedly connected to the second rotating shaft 32 at the opposite ends, and the third sprocket 35 on the first roller 15 is located in one of the sliding boxes 13, and the third sprocket 35 on the second roller 16 is located in the other sliding box 13, and the third sprocket 35 on the adjacent first roller 15 is driven by a chain, and the third sprocket 35 on the adjacent second roller 16 is driven by a chain; a group of first rollers 15 and a group of second rollers 1 The second rotating shaft 32 on the first roller 15 and the second roller 16 which are farthest apart in 6 and the first rotating shaft 31 of the first motor 3 in the opposite position are connected through a starting assembly; the opposite ends of a pair of lead screws 25 extend into the sliding box 13 respectively and are fixedly connected with the first sprocket 33; the first rotating shaft 31 is rotatably connected with the second sprocket 34, and the adjacent first sprocket 33 and second sprocket 34 are driven by a chain; when working, a group of first rollers 15 and a group of second rollers 16 are driven by different first motors 3 respectively, and at the same time, a group of first rollers 15 rotates in the same direction and at the same speed through the setting of the third sprocket 35 and the chain, and the same is true for a group of second rollers 16, and a pair of lead screws 25 are also driven by different first motors 3 respectively, and the rotation of the lead screw 25 is rotated by the setting of the first sprocket 33, the second sprocket 34 and the chain.

[0041] The starting assembly includes a starting unit and a first annular block 41; a first through slot 4 is provided on the first rotating shaft 31; a first annular block 41 is sleeved on the outer wall of the first rotating shaft 31; a first sliding rod 42 is fixedly connected to the side wall of the first through slot 4 close to the second rotating shaft 32 through a spring, and the first sliding rod 42 is slidably connected in the first through slot 4; both ends of the first sliding rod 42 are fixedly connected to the inner ring wall of the first annular block 41; the diameter of the first rotating shaft 31 is smaller than the diameter of the second rotating shaft 32; a group of first clamping grooves are provided on the side wall of the second rotating shaft 32 close to the first rotating shaft 31 47, a group of second positioning grooves 48 are provided on the side wall of the second sprocket 34 close to the first annular block 41, and the group of first positioning grooves 47 and the group of second positioning grooves 48 are both arranged in an annular shape; the first positioning posts 45 and the second positioning posts 46 are respectively fixedly connected to the side walls of the first annular block 41, and the first positioning posts 45 and the second positioning posts 46 are respectively arranged corresponding to the first positioning grooves 47 and the second positioning grooves 48; a fixed block 44 is fixedly connected to the side wall of the first sliding rod 42 away from the second rotating shaft 32; an electromagnetic block 43 is fixedly connected to the side wall of the first through groove 4 away from the second rotating shaft 32, and When the electromagnetic block 43 is energized, the electromagnetic block 43 and the fixed block 44 attract or repel each other; when working, in the initial state, the first annular block 41 is limited by the spring, and the first locking column 45 and the second locking column 46 on the first annular block 41 are both out of the first locking groove 47 and the second locking groove 48. At this time, the first roller 15 and the second roller 16 are both in a free rotation state. When the material is fed from the opening on one side of the placement chamber 11, the starting unit will be triggered to allow the electromagnetic block 4 in the first rotating shaft 31 on the first motor 3 on the other side of the placement chamber 11 to rotate. 3 is powered on, and the first motor 3 at this position rotates. At this time, the electromagnetic block 43 is powered on to make the first annular block 41 move toward the position of the electromagnetic block 43, so that the second clamping column 46 is clamped into the second clamping groove 48, so that the first motor 3 at this position rotates and then the blocking rod 26 at the other side of the placement cavity 11 follows the rotation column 21 through the setting of the first sprocket 33, the second sprocket 34 and the chain, so as to perform material blocking. After the material is completely entered, the starting unit will delay closing (the delayed closing time can be set), so as to delay the recovery of the blocking rod 26 to ensure the continuity of the blocking;When discharging, the material is discharged from the opening on the other side of the placement chamber 11. At this time, the electromagnetic block 43 on the first rotating shaft 31 on the first motor 3 near the outlet position on the other side of the placement chamber 11 passes the opposite current, so that the first annular block 41 approaches the direction of the second rotating shaft 32, and the first clamping column 45 is clamped into the first clamping groove 47. The material is discharged by the rotation of the first roller 15 or the second roller 16. When the material passes through the opening on the other side of the placement chamber 11, the starting unit located at the opening on one side of the placement chamber 11 will be triggered, so that the first motor 3 and the electromagnetic block 43 on the first rotating shaft 31 located at the opening on one side of the placement chamber 11 will be started, so that the first annular block 41 moves toward the position of the electromagnetic block 43, so that the corresponding blocking rod 26 rotates out, and the situation of material backflow discharge is avoided.

At the same time, the annular airbag 64 is squeezed by the pushing member to expand the annular rubber ring 63, so that the annular rubber ring 63 bulges out of the first annular groove 61, and then makes it fit with the bottom surface of the material, thereby increasing the friction force and playing a stabilizing role. At the same time, when the material is discharged and fed, the first hydraulic cylinder 14 will drive the sliding box 13 to move upward, and the pushing member will be released from work, and the annular rubber ring 63 will shrink, which will not affect the material discharge and feeding operations.

[0044] The pushing member includes an extrusion plate 7; a group of first rollers 15 and a group of second rollers 16 are provided with second annular grooves 72 on their outer side walls near both ends; except for the first rollers 15 and the second rollers 16 which are the farthest apart, the other first rollers 15 and the second rollers 16 adjacent thereto are provided with second through grooves 73 in the second annular grooves 72 at the opposite ends; a second sliding rod 75 is slidably connected in the second through groove 73, and an annular conical block 74 is fixedly connected at both ends of the second sliding rod 75, and the annular conical block 74 is sleeved in the second annular groove 72; an extrusion plate 7 is slidably connected in the cylindrical cavity 62, and the extrusion plate 7 is fixedly connected to the side wall of the cylindrical cavity 62 by a spring; a group of extrusion plates 7 are fixed by a pushing column 71 The first chute 12 is connected with a fixing plate 76, and a first inclined surface 77 is provided on the fixing plate 76, and the length of the fixing plate 76 is less than the distance between the opposite surfaces of a pair of connecting blocks 2; when working, when the sliding box 13 descends, the annular conical block 74 will be pushed by the first inclined surface 77, so that the annular conical block 74 drives the second sliding rod 75 to move, and drives the extrusion plate 7 to squeeze the annular airbag 64, so as to complete the expansion of the annular rubber ring 63, and when the sliding box 13 moves upward as a whole, the annular conical block 74 will be separated from the push of the fixing plate 76, so that the annular conical block 74 and the extrusion plate 7 are restored to their original positions, and the annular rubber ring 63 is restored to their original positions.

[0045] A pair of sliding boxes 13 are both fixedly connected with a second hydraulic cylinder 8, and the hydraulic rod of the second hydraulic cylinder 8 is fixedly connected with a push plate 81, and the push plate 81 is slidably connected to the inside of the sliding box 13; a push rod 82 is fixedly connected to the push plate 81, and the push rod 82 passes through the outer wall of the sliding box 13 and the position of the push rod 82 corresponds to the position of the annular conical block 74. When the push rod 82 moves, the annular conical block 74 will be pushed to move; during operation, when the material is discharged, the first roller 15 or the second roller 16 will rotate, thereby pushing the material out. When the friction force is not enough to push the material (the material slips), the second hydraulic cylinder 8 on one side can be started at this time to move the push plate 81, and then the annular conical block 74 is pushed to move through the push rod 82, so that the annular rubber ring 63 on the rotating first roller 15 or the second roller 16 at this time expands, so as to increase the friction force and facilitate the pushing of the material (targeted use).

[0046] A pair of symmetrically distributed L-shaped columns 83 are fixedly connected to the side wall of the connecting block 2, and a pressure sensor 84 is provided on the vertical column side wall of the L-shaped column 83; a contact rod 85 used in conjunction with the pressure sensor 84 is fixedly connected to the side wall of the baffle rod 26; during operation, when the material is discharged or fed, the corresponding first motor 3 will continue to work, and then drive the lead screw 25 to work all the time, which will cause the baffle rod 26 to rotate too much and get stuck. Therefore, a pressure sensor 84 is provided. When the baffle rod 26 rotates to 90 degrees, it will hit the pressure sensor 84 through the contact rod 85, and then the first motor 3 that is working at this time will be powered off, thereby avoiding getting stuck (at the same time, early warning operations such as warning lights are performed, which are not explained in the prior art).

[0047] An isosceles triangle block 86 is fixedly connected to the bottom of the placement chamber 11; third through grooves 87 are opened on the side walls of the placement chamber 11, and the third through grooves 87 are located below the openings on both sides of the placement chamber 11; during operation, some fallen impurities will flow out from the gap between the first roller 15 and the second roller 16, and then flow out through the third through grooves 87, avoiding the impurities from being retained in the first roller 15 and the second roller 16, and also facilitating the discharge operation of the impurities.

[0048] An operating method of an unmanned intelligent transport device for cargo transfer, the method is as follows:

[0049] S1: When feeding, the height of the sliding box 13 is adjusted by the first hydraulic cylinder 14, so as to adjust the top positions of the first roller 15 and the second roller 16 to be slightly lower than the production line height. At this time, the material flows down from the production line and then is fed through the opening on one side of the placement chamber 11;

[0050] S2: When the material enters from the opening on one side of the placement chamber 11, the lead screw 25 located at the opening on the other side of the placement chamber 11 is rotated by the power member, thereby driving a pair of rack plates 24 to move toward each other, and the meshing of the rack plates 24 and the teeth 22 allows the rotating column 21 to rotate, allowing the blocking rod 26 on the rotating column 21 to rotate and block the opening on the other side of the placement chamber 11 to block the material. After the material completely enters the placement chamber 11, the power member will be delayed to close, and then the rotating column 21 will rotate under the action of the torsion spring force, allowing the blocking rod 26 and the rack plate 24 to return to their original positions, and the feeding is completed;

[0051] S3: After feeding, the sliding box 13 is lowered by the first hydraulic cylinder 14, so that the top ends of the first roller 15 and the second roller 16 are lower than the opening bottom surface of the placement chamber 11;

[0052] S4: When discharging, the rolling door is opened, and the sliding box 13 is raised as a whole through the first hydraulic cylinder 14 to make it slightly higher than the production line height, and then the first roller 15 or the second roller 16 is driven by the power member to rotate and discharge the material. At the same time, when the power member is rotating, the baffle 26 away from the material outlet position will open again. This is to prevent the material from flowing back. Then, after the discharging is completed, the baffle 26 returns to its original position, that is, the discharging is completed.

[0053] Working principle: When feeding, first adjust the height of the sliding box 13 through the first hydraulic cylinder 14, so as to adjust the top position of the first roller 15 and the second roller 16 to be slightly lower than the production line height. At this time, the material flows down from the production line, and then is fed through the opening on one side of the placement chamber 11. At this time, the first roller 15 and the second roller 16 are both in a non-braking state, which can facilitate the entry of the material. When the material enters from the opening on one side of the placement chamber 11, the lead screw 25 located at the opening on the other side of the placement chamber 11 is rotated by the power part, thereby driving a pair of rack plates 24 to move toward each other. Through the meshing of the rack plate 24 and the teeth 22, the rotating column 21 is rotated, and the stop rod 26 on the rotating column 21 is rotated. It is made to block the opening on the other side of the placement chamber 11 to block and brake the material, and the rubber block 27 on the side wall of the blocking rod 26 can reduce the rigid collision, and the blocking rod 26 can limit the position. After the material completely enters the placement chamber 11, the power part will be delayed to close (existing technology), and then the rotating column 21 is rotated under the action of the torsion spring force, so that the blocking rod 26 and the rack plate 24 are restored to their original positions, and the feeding is completed. At the same time, the sliding box 13 is lowered by the first hydraulic cylinder 14, so that the top of the first roller 15 and the second roller 16 are lower than the opening bottom surface of the placement chamber 11; when discharging, the rolling door is opened, and the sliding box 13 is driven to be adjusted upward as a whole by the first hydraulic cylinder 14, so that its bottom is slightly higher than The height of the production line is set, and then the power part drives the first roller 15 or the second roller 16 to rotate and unload the material. At the same time, when the power part rotates, the baffle 26 away from the material outlet position will be opened. This is to prevent the material from flowing back. Then, after the material is discharged, the baffle 26 returns to its original position, that is, the material is discharged. Through the above operation, the baffle 26 can be used to effectively brake the forward potential energy of the material when the material is fed. At the same time, the baffle 26 will not occupy the space between the vehicle body 1 and the placement chamber 11 and the external space, effectively avoiding the situation where the rolling door is damaged or the material is separated (the adjustment of the first hydraulic cylinder 14 is processed by the distance sensor); the material is placed in the placement chamber 11 During transportation, in order to avoid the shaking of the materials, after the materials enter a group of first rollers 15 and second rollers 16, the first hydraulic cylinder 14 will drive the sliding box 13 to descend, and the bottom end of the sliding box 13 will fit on the bottom end of the first slide groove 12. At the same time, the annular airbag 64 will be squeezed by the pushing member to expand the annular rubber ring 63, so that the annular rubber ring 63 will bulge out of the first annular groove 61, and then fit with the bottom surface of the materials, increase the friction force, and play a stabilizing role; at the same time, when the materials are discharged and fed, the first hydraulic cylinder 14 will drive the sliding box 13 to move upward, and the pushing member will be released, and the annular rubber ring 63 will shrink, which will not affect the discharge and feeding operations of the materials.
