Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to material transportation equipment. Background Art

[0002] At present, materials are mainly transported by logistics trolleys. The logistics trolleys are divided into two layers, and the upper layer is generally placed with material boxes containing parts. The operator moves the logistics trolley to the production line shelf. The production line shelf is generally divided into two layers, and the upper layer is generally placed with material boxes containing parts, and the lower layer is generally placed with empty material boxes. When replenishing materials, the operator manually pushes the material box on the upper layer of the logistics trolley to the upper layer of the production line shelf. This process is not only manpower-consuming, but also very inconvenient for the operator to operate due to the high height of the upper layer of the production line shelf. After the operator delivers the material box to the upper layer of the production line shelf, he has to bend down again to move the empty material box on the lower layer of the production line shelf to the lower layer of the logistics trolley. This process requires the operator to bend down and carry it many times. As the number of times increases, the operator may suffer from lumbar muscle strain, affecting the operator's physical health. In addition, the entire process of exchanging empty and real parts takes a long time, the operator's operating efficiency is low, and it will also cause waste of working time and road congestion.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0028] At present, the transportation of materials is mainly carried out by logistics trolleys. The logistics trolleys are divided into two layers, the upper layer is generally placed with material boxes containing parts, and the operator moves the logistics trolley to the production line shelf. The production line shelf is generally divided into two layers, the upper layer is generally placed with material boxes containing parts, and the lower layer is generally placed with empty material boxes. When replenishing materials, the operator manually pushes the material box located on the upper layer of the logistics trolley to the upper layer of the production line shelf. This process is not only labor-intensive, but also very inconvenient for the operator to operate due to the high height of the upper layer of the production line shelf. After the operator delivers the material box to the upper layer of the production line shelf, he must bend down again to move the empty material box located on the lower layer of the production line shelf to the lower layer of the logistics trolley. This process requires the operator to bend down and carry it many times. As the number of times increases, it may cause lumbar muscle strain to the operator, affecting the operator's physical health, and the entire process of empty and real parts exchange takes a long time, the operator's operating efficiency is low, and it will also cause waste of working time and road congestion. The utility model proposes a material transportation device 100.

[0029] See also Figures 1 to 3 In one embodiment of the utility model, the material transport equipment 100 includes a shelf 1, a trolley 2 and a feeding mechanism 3. The shelf 1 includes a shelf body 11 and an upper storage platform 12 and a lower storage platform 13 arranged on the shelf body 11 at intervals in the vertical direction; the trolley 2 includes a frame 21 and an upper storage rack 22 and a lower storage rack 23 arranged on the frame 21 at intervals in the vertical direction. The upper storage rack 22 includes a first end 221 and a second end 222 arranged oppositely. The height of the first end 221 is lower than the height of the second end 222. The height of the first end 221 is the same as the height of the upper storage platform 12 facing the trolley. The height of one end of the trolley 2 is adapted so that the first material located on the upper storage rack 22 can be moved from the first end 221 to the upper storage platform 12 under the action of gravity; the lower storage rack 23 includes a third end 231 and a fourth end 232 arranged opposite to each other, and the height of the third end 231 is adapted to the height of one end of the lower storage platform 13 facing the trolley 2; the feeding mechanism 3 includes a driving device 31 and a feeding member 32 connected to the driving device 31 in a transmission manner, and the driving device 31 is used to drive the feeding member 32 to feed the second material located on the lower storage platform 13 from the third end 231 to the lower storage rack 23.

[0030] The technical solution of the utility model uses a trolley 2 to transport materials. The operator pushes the trolley 2 to move to the shelf 1. Since the height of the first end 221 of the upper shelf 22 is lower than the height of the second end 222, the first material on the upper shelf 22 slides from the upper shelf 22 to the upper storage platform 12 under the action of gravity, which saves manpower and reduces the difficulty of moving the first material to the upper storage platform 12. At the same time, the driving device 31 drives the feeding member 32 to move, so that the feeding member 32 moves the second material located on the lower storage platform 13 to the lower shelf 23, eliminating the process of the operator bending over to carry the second material, saving manpower, and avoiding the occurrence of lumbar muscle strain caused by the operator bending over to carry the second material. Since the transportation of the first material and the second material can be carried out simultaneously, the time consumed in the process is reduced, thereby reducing the probability of the trolley 2 causing road congestion. Among them, the first material can be a material box 200 filled with parts, and the second material can be an empty material box 200. It should be noted that, when the trolley 2 has not yet arrived at the shelf 1, the operator can manually block the first material on the upper storage rack 22 from sliding out from the first end 221, or it can be blocked by a blocking member, which is rotatably connected to the frame 21, and the blocking member is rotated according to the blocking requirement to block or release the first material. It should also be noted that rollers can be installed at the bottom of the first material so that the first material can move more smoothly from the first end 221 to the upper storage table 12, or the upper storage rack 22 can be provided with a smooth strip or multiple rollers so that the first material can move more smoothly from the first end 221 to the upper storage table 12. It should also be noted that the drive device 31 can be a cylinder or a pneumatic slider, etc.

[0031] According to one embodiment of the utility model, the height of the first end 221 may be no lower than the height of the upper storage platform 12, the height of the first end 221 may be slightly lower than the height of the end of the upper storage platform 12 facing the trolley 2, the height of the third end 231 may be no higher than the height of the lower storage platform 13, and the height of the third end 231 may be slightly higher than the height of the end of the lower storage platform 13 facing the trolley 2.

[0032] In one embodiment, the driving device 31 includes a driving component 311 and an elastic reset member 312. The driving component 311 is connected to the feeding member 32 in a transmission manner. The feeding member 32 includes a starting position. The driving component 311 can drive the feeding member 32 located at the starting position to move, so that the feeding member 32 drives the second material located on the lower storage table 13 to move until the second material moves from the third end 231 to the lower storage rack 23. One end of the elastic reset member 312 is connected to the rack body 11, and the other end of the elastic reset member 312 is connected to the feeding member 32. The elastic reset member 312 can drive the feeding member 32 to move to the starting position. The position of the feeding member 32 before the driving component 311 drives the feeding member 32 to move is the starting position. When the parts in the material box 200 on the upper storage table 12 are consumed, the operator moves the empty material box 200 to the right side of the feeding member 32. When the trolley 2 moves to the shelf 1, the driving component 311 drives the feeding member 32 to move to the right, thereby driving the empty material box 200 to move from the lower storage table 13 to the lower storage rack 23. During this process, the elastic reset member 312 is in a stretched state. After the empty material box 200 moves to the lower storage rack 23, the driving component 311 is reset, and the feeding member 32 moves to the left to the starting position under the action of the elastic reset member 312, thereby realizing the automatic feeding and reset of the feeding member 32. It should be noted that the feeding member 32 can be a feeding plate or a feeding rod. It should also be noted that the elastic reset member 312 can be a tension spring or an elastic pull rope.

[0033] In one embodiment, the driving assembly 311 includes a cylinder 3111, a movable pulley 3112, a fixed pulley 3113 and a pull rope 3114. The cylinder 3111 and the fixed pulley 3113 are both connected to the frame body 11, the output shaft of the cylinder 3111 is connected to the movable pulley 3112, one end of the pull rope 3114 is connected to the frame body 11, and the other end of the pull rope 3114 is connected to the feeding piece 32 after passing through the movable pulley 3112 and the fixed pulley 3113. The cylinder 3111 can drive the feeding piece 32 located at the starting position to move through the movable pulley 3112, the fixed pulley 3113 and the pull rope 3114. The output shaft of the cylinder 3111 extends out, thereby driving the movable pulley 3112 to move to the left, and then pulling the feeding piece 32 to move to the left through the pull rope 3114. By arranging the movable pulley 3112 on the output shaft of the cylinder 3111, compared with the output shaft of the cylinder 3111 directly connected to the feeding piece 32 through the pull rope 3114, when the stroke of the output shaft of the cylinder 3111 is constant, the use of the movable pulley 3112 can effectively extend the moving stroke of the feeding piece 32, so that when the stroke of the cylinder 3111 remains unchanged, the feeding piece 32 can be pushed farther, so that the empty material box 200 can be smoothly delivered to the lower storage rack 23.

[0034] In one embodiment, the material transport equipment 100 further includes a detection component 4, which is mounted on the rack body 11. The trolley 2 includes a material change station. When the trolley 2 is at the material change station, the driving device 31 can drive the feeding member 32 to send the second material on the lower storage platform 13 from the third end 231 to the lower storage rack 23. The detection component 4 is used to detect whether the trolley 2 is at the material change station. The position where the trolley 2 and the shelf 1 are exchanged for empty and full is the material change station. By setting the detection component 4, when the detection component 4 detects that the trolley 2 moves to the material change station, the driving component 311 drives the feeding member 32 to move, pushing the empty material box 200 to move to the lower storage rack 23, eliminating the process of manually operating the driving component 311.

[0035] In one embodiment, the detection component 4 includes a contact switch, which is installed on the rack body 11. The contact switch is used to detect whether the trolley 2 is located at the refueling station. When the shelf 1 moves to the refueling station, the shelf 1 will touch the contact switch first. As the shelf 1 moves, the contact switch will also move. When the shelf 1 moves to the refueling station, the contact switch moves to a position where it can trigger and send detection information, so that the control module can understand that the trolley 2 has moved to the refueling station through the detection information, and then control the cylinder 3111 through the control module to drive the movable pulley 3112 to move to the left.

[0036] According to an embodiment of the present utility model, the detection assembly 4 includes a photoelectric detection switch, which is installed on the frame body 11 and is used to detect whether the trolley 2 is located at the material changing station.

[0037] In one embodiment, the material transportation equipment 100 also includes a first limiting mechanism 5, the first limiting mechanism 5 includes a first limiting assembly 51 and a first reset member 52, the first limiting assembly 51 is movably connected to the upper storage rack 22, the first limiting assembly 51 includes a first limiting position and a first release position, the first limiting assembly 51 can reciprocate between the first limiting position and the first release position, so that the first limiting assembly 51 blocks the first material from leaving the upper storage rack 22 from the first end 221 or releases the first material from the first end 221 to leave the upper storage rack 22; one end of the first reset member 52 is connected to the first limiting assembly 51, and the other end of the first reset member 52 is connected to the upper storage rack 22, and the first reset member 52 can drive the first limiting assembly 51 to move from the first release position to the first limiting position; the first limiting assembly 51 is used to abut against the frame body 11, and the frame 21 can move relative to the frame body 11, so that the frame body 11 can drive the first limiting assembly 51 to move from the first limiting position to the first release position. During the movement of the trolley 2, the first limit assembly 51 is always in the first limit position under the action of the first reset member 52, thereby limiting the material box 200 from sliding out from the first end 221. When the trolley 2 approaches the material change station, the frame body 11 will first contact the first limit assembly 51 and drive the first limit assembly 51 to move from the first limit position to the first release position. At this time, the first reset member 52 is in a stretched state. When the trolley 2 moves to the material change station, the first limit assembly 51 just moves to the first release position. At this time, the material box 200 can move smoothly from the first end 221 to the upper storage table 12, thereby realizing the automatic movement of the material box 200 from the upper storage rack 22 to the upper storage table 12 without relying on electrical equipment, saving energy consumption. It should be noted that when the trolley 2 leaves the material change station, the first limit assembly 51 will be restored to the first limit position from the first release position under the action of the first reset member 52.

[0038] In one embodiment, the first limit component 51 includes a first trigger member 511 and a first limit member 512, and the first trigger member 511 and the first limit member 512 are both slidably matched with the upper storage rack 22. The first limit member 512 includes a first limit position and a first release position. The end of the first trigger member 511 away from the first limit member 512 is used to abut against the upper storage platform 12, so that the first trigger member 511 can drive the first limit member 512 to move from the first limit position to the first release position. The first reset member 52 includes a first spring, one end of the first spring is connected to the upper storage rack 22, and the other end of the first spring is connected to the first limit member 512, so that the first spring can drive the first limit member 512 to move from the first release position to the first limit position. The first trigger member 511 can slide horizontally relative to the upper storage rack 22, and the first limit member 512 can slide in the vertical direction relative to the upper storage rack 22. The left end of the first trigger member 511 will first contact the shelf 1. In the process of the trolley 2 moving to the material changing station, the shelf 1 will push the first trigger member 511 to move right, and the first trigger member 511 moving right will drive the first limit member 512 to move downward from the first limit position and gradually approach the first release position. During this process, the first spring is in a stretched state. When the trolley 2 moves to the material changing station, the first limit member 512 just moves to the first release position. At this time, the material box 200 can move smoothly from the first end 221 to the upper storage table 12, thereby realizing the automatic movement of the material box 200 from the upper storage rack 22 to the upper storage table 12 without relying on electrical equipment, saving energy consumption.

[0039] According to one embodiment of the utility model, the first limit assembly 51 includes an L-shaped rod, which is slidably matched with the upper storage rack 22 so that the L-shaped rod can move obliquely upward or downward relative to the upper storage rack 22. One end of the L-shaped rod is used to abut against the shelf 1, and the other end of the L-shaped rod is used to connect with the first reset member 52, and the end is also used to prevent the material box 200 from sliding out from the first end 221. When the trolley 2 moves to the material changing station, the shelf 1 can drive the L-shaped rod to move obliquely downward so that the L-shaped rod moves from the first limit position to the first release position. After the trolley 2 moves to the material changing station, the L-shaped rod is located at the first release position; when the trolley 2 leaves the material changing station, the L-shaped rod will move obliquely upward to the first limit position under the action of the first reset member 52.

[0040] In one embodiment, the material transportation equipment 100 also includes a second limiting mechanism (not shown in the figure), the second limiting mechanism includes a second limiting assembly and a second reset member, the second limiting assembly is movably connected to the lower storage platform 13, the second limiting assembly includes a second limiting position and a second release position, and the second limiting assembly can reciprocate between the second limiting position and the second release position, so that the second limiting assembly blocks the second material from moving from the lower storage platform 13 to the lower storage rack 23 or releases the second material from the lower storage platform 13 to the lower storage rack 23; one end of the second reset member is connected to the second limiting assembly, and the other end of the second reset member is connected to the lower storage platform 13, and the second reset member can drive the second limiting assembly to move from the second release position to the second limiting position; the second limiting assembly is used to abut against the frame 21, and the frame 21 can move relative to the frame body 11, so that the frame 21 can drive the second limiting assembly to move from the second limiting position to the second release position. During the movement of the trolley 2, the second limit assembly is always in the second limit position under the action of the second reset member, thereby limiting the material box 200 from sliding out from the lower storage platform 13 toward one end of the trolley 2. When the trolley 2 approaches the material change station, the frame 21 will first contact the second limit assembly and drive the second limit assembly to move from the second limit position to the second release position. At this time, the second reset member is in a stretched state. When the trolley 2 moves to the material change station, the second limit assembly just moves to the second release position. At this time, the material box 200 can be smoothly moved from the third end 231 to the lower storage rack 23 under the drive of the drive device 31, avoiding the phenomenon that the empty material box 200 slides out from the lower storage platform 13 toward one end of the trolley 2 before the trolley 2 reaches the material change station. It should be noted that when the trolley 2 leaves the material change station, the second limit assembly will be restored from the second release position to the second limit position under the action of the second reset member.

[0041] According to one embodiment of the utility model, the second limit assembly includes a second trigger member and a second limit member, and the second trigger member and the second limit member are both slidably matched with the lower storage platform 13, and the second limit member includes a second limit position and a second release position. The end of the second trigger member away from the second limit member is used to abut against the trolley 2, so that the second trigger member can drive the second limit member to move from the second limit position to the second release position, and the second reset member includes a second spring, one end of the second spring is connected to the lower storage platform 13, and the other end of the second spring is connected to the second limit member, so that the second spring can drive the second limit member to move from the second release position to the second limit position. The second trigger member can slide horizontally relative to the lower storage table 13, and the second limit member can slide in the vertical direction relative to the lower storage table 13. The right end of the second trigger member will first contact the trolley 2. In the process of the trolley 2 moving to the material changing station, the trolley 2 will push the second trigger member to move to the right. The second trigger member moving to the right will drive the second limit member to move downward from the second limit position and gradually approach the second release position. During this process, the second spring is in a stretched state. When the trolley 2 moves to the material changing station, the second limit member just moves to the second release position. At this time, the material box 200 can be smoothly moved from the third end 231 to the lower storage rack 23, avoiding the phenomenon that the empty material box 200 leaves the lower storage table 13 from the third end 231 before the trolley 2 reaches the material changing station.

[0042] In one embodiment, the height of the third end 231 is higher than the height of the fourth end 232, and the trolley 2 further includes a material stopper 6, which is connected to the frame 21 and is located at the fourth end 232, so that the material stopper 6 can stop the second material located on the lower shelf 23 from leaving the lower shelf 23 from the fourth end 232. By providing the material stopper 6, the empty material box 200 located on the lower shelf 23 is prevented from leaving the lower shelf 23 from the fourth end 232, thereby improving the reliability of the transportation of the empty material box 200.

[0043] In one embodiment, the upper storage platform 12 includes a fifth end 121 and a sixth end 122 that are relatively arranged along the length direction of the upper storage platform 12, and the height of the sixth end 122 is higher than the height of the fifth end 121, so that the first material can move from the sixth end 122 to the fifth end 121 under the action of gravity. The height of the sixth end 122 is higher than the height of the fifth end 121, so that the first material can move from the sixth end 122 to the fifth end 121 under the action of gravity, which is convenient for the operator at the fifth end 121 to take the material. It should be noted that the upper storage platform 12 is provided with a plurality of rollers so that the first material can move smoothly thereon.

[0044] According to an embodiment of the present invention, a plurality of rollers are arranged at intervals at the bottom of the frame 21 to facilitate the movement of the frame 21 .

[0045] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
