Description

Technical Field

[0001] The invention relates to the technical field of warehousing logistics, in particular to a jacking type tray stacking machine with shaping function. Background Art

[0002] As a material or product carrying device, pallets are widely used in the automated storage and logistics system of factory workshops. The pallet unstacker is a device used to automatically stack and unstacker empty pallets. Its function is to stack the empty pallets transferred from the upper-level logistics system, with the purpose of saving floor space. When the empty pallets need to be used, the stacked empty pallets are automatically unstackered for use by the next-level logistics system.

[0003] In the non-standard equipment stereoscopic warehouse conveying system, pallet removers and stackers are often used before and after the goods are put on the shelves. However, during use, the pallets are often stacked unevenly, causing operational defects of the pallet remover and stacker systems, and have a great impact on subsequent work. The current solution is to add a pallet shaping machine to shape the entire pile of pallets, or to add a set of pneumatic or electric blocking devices on both sides of the end of the equipment, but this will increase the total cost of equipment use.

[0004] After searching, a new type of pallet destacking machine with patent number CN202320474184.X was found. When the pallet destacking machine slides onto the roller above the pallet sliding part, the roller is rotated to one side until it reaches the baffle by rotating the motor in cooperation with the transmission belt to fix the position of the pallet. At the same time, the second push rod motor fixed on the mounting frame cooperates with the first push rod motor sliding on the side end of the mounting frame to stack the placed pallets, thereby solving the problem of stacking the pallets flat. There is also a connecting rod fork mechanism and a pallet destacking machine with patent number CN202322717863.8. In the pallet destacking machine, the connecting rod fork mechanism cooperates with the lifting mechanism to realize the automatic stacking and splitting functions of the pallets on the pallet conveyor line, and can also be used in conjunction with a forklift to realize the automatic stacking and splitting functions of the pallets.

[0005] However, the destacking machine has a complex structure, is troublesome to use, has a simple effect, has a high production cost, has low reliability, and has poor adjustability during use.

A jacking power assembly is arranged between the two frame bodies 10. A destacking frame assembly 1 for assisting pallet shaping is installed on the two frame bodies 10. The jacking power assembly includes a jacking machine assembly 5, a power assembly 6 installed in the jacking machine assembly 5, and a blocking assembly 7 installed on both sides of the jacking machine assembly 5 symmetrically. A detection frame for cooperating with the destacking frame assembly 1 to detect the position of the pallet is also installed on the two frame bodies 10.

[0051] When the device is needed to be used, the lifting machine assembly 5 and the two stacking tray frame assemblies 1 are first installed on the frame body 10. After they are fixed, the conveyor 8 is started. The pallets to be stacked are transported to the lifting machine assembly 5 in sequence by the conveyor 8, and the pallets are lifted by the lifting power assembly. The stacking tray frame assembly 1 is started to fix the pallets. After they are fixed, the lifting power assembly is lowered, and the conveyor 8 transports the next pallet to the lifting machine assembly 5 for stacking again.

[0052] By means of the detection frames arranged on both sides of the frame body 10 , the jacking position can be detected by the detection frames during use.

[0053] For example 2, please refer to Figure 1 , Figure 6 , Figure 7 Figure 8 and Fig. 9 The stacking disk rack assembly 1 includes a fixed plate 13, a top plate 11 is installed just above the fixed plate 13, two guide rails 17 are installed on the fixed plate 13, and side forks 15 are slidably connected to the two guide rails 17, and a connecting plate 19 is arranged on the top of the two side forks 15, and the two ends of the connecting plate 19 are respectively fixed to the two side forks 15, and the top of the connecting plate 19 is rotatably connected to two swing plates 14, and the tops of the two swing plates 14 are respectively installed with two side rollers 12, and the tops of the two side rollers 12 are slidably connected to the bottom of the top plate 11, and shaping components 3 are also arranged on both ends of the fixed plate 13, each shaping component 3 includes a driving gear 31, and the driving gear 31 is installed at the bottom of the swing plate 14, and the bottom of the driving gear 31 is rotatably connected to the fixed plate 13, and one side of the driving gear 31 is meshed with a driven gear 32, and the fixed plate 13 is provided with a plurality of gears 31 on both ends. It is also rotatably connected with a transverse whole plate 35, and a transverse whole roller 18 is installed on the top of each transverse whole plate 35. The tops of the two transverse whole rollers 18 are rotatably connected to the bottom of the top plate 11. A rocker 34 is installed at the bottom of the driven gear 32. The end of the rocker 34 away from the driven gear 32 is hinged with a connecting rod 33, and the other end of the connecting rod 33 is rotatably connected to the adjacent transverse whole plates 35. An in-and-out motor 16 is also installed at the bottom of the fixed plate 13. The output end of the in-and-out motor 16 is fixedly connected to the first transmission shaft through a coupling. The first transmission shaft is rotatably connected to the top of the fixed plate 13. The top of the fixed plate 13 is also rotatably connected to the second transmission shaft. A transmission belt is arranged between the first transmission shaft and the second transmission shaft. The first transmission shaft and the second transmission shaft are connected through the transmission belt. A connecting block is arranged on the transmission belt, and the top of the connecting block is slidably connected to the bottom of the connecting plate 19.

[0054] When stacking, first start the conveyor 8, transport the pallet to be stacked to the lifting assembly 5 through the conveyor 8, start the lifting assembly 5, lift the pallet upward through the lifting assembly 5, and when the pallet moves upward, start the in-out motor 16 at the same time, drive the transmission belt to rotate through the in-out motor 16, so that the transmission belt drives the connecting plate 19 to move, and when the connecting plate 19 moves, the two side forks 15 slide outward along the guide rail 17 at the same time, so that the side forks 15 on both sides extend outward and are inserted into the pallet to fix the pallet;

[0055] At the same time, when the connecting plate 19 moves outward, the swing plates 14 arranged at both ends of the connecting plate 19 slide along the sliding grooves on the connecting plate 19. When the swing plate 14 moves to the end of the sliding groove, the connecting plate 19 continues to slide forward. Under the action of the thrust of the connecting plate 19, the two swing plates 14 begin to rotate along the sliding grooves, and the driving gears 31 arranged at the other ends of the two swing plates 14 rotate under the action of the swing plates 14. When the driving gear 31 rotates, the driven gear 32 meshing with the driving gear 31 rotates synchronously. When the driven gear 32 rotates, the rocker 34 connected to the driven gear 32 moves outward under the action of the driven gear 32, and at the same time pushes the connecting rod 33 to move outward, so that the connecting rod 33 pushes the horizontal plate 35 to rotate on the fixed plate 13, so that the horizontal roller 18 rotates under the drive of the horizontal plate 35. The pallet is shaped by the horizontal roller 18, and the horizontal and side adjustments of the pallet are achieved by the arrangement of multiple side rollers 12 and the horizontal roller 18, so as to ensure the neat stacking of the pallet.

[0056] After multiple side forks 15 fix the pallet, the lifting assembly 5 moves downward and resets, and the conveyor 8 transports the next pallet to the lifting assembly 5. The lifting assembly 5 performs the lifting movement again. When the lifting assembly 5 is lifted upward, the in-and-out motor 16 is started again, so that the transmission belt drives the connecting plate 19 to move and reset, and the two side forks 15 are retracted. When the two side forks 15 are fully retracted, the pallet on the lifting assembly 5 contacts the bottom of the previous pallet and moves upward at the same time under the action of the lifting assembly 5, so that the pallet below moves to the front of the side forks 15, and the in-and-out motor 16 is started, so that the two side forks 15 extend forward to fix the pallet, thereby realizing the stacking of the pallets.

[0057] For example 3, please refer to Figure 1 , Figure 6 , Figure 8 and Fig.10, a disinfection assembly 4 is also provided on the connecting plate 19, and the disinfection assembly 4 includes a liquid storage tank 41, and the water outlet end of the liquid storage tank 41 is connected to a piston cylinder 42 through a hose, and a piston rod is slidably connected to the inside of the piston cylinder 42, and the end of the piston rod away from the piston cylinder 42 is fixedly connected to the connecting plate 19, and the disinfection assembly 4 also includes an adjusting gear 46, and a pressurized tank 43 is installed on the top of the adjusting gear 46. The water inlet end of the pressurized tank 43 is connected to the piston cylinder 42 through a connecting pipe, and the water outlet end of the pressurized tank 43 is connected to a nozzle 44, and the spraying hole of the nozzle 44 is arranged to be inclined downward, and the active The water inlet and outlet ends of the plug cylinder 42 are both provided with a one-way valve, the disinfection component 4 also includes a movable rack 45 centrally and symmetrically installed on both sides of the adjusting gear 46, the two movable racks 45 are meshed with the adjusting gear 46, the ends of the two movable racks 45 that are away from each other are respectively fixed to the adjacent swinging plates 14, a detection component 2 is also installed on the side of the fixed plate 13 close to one of the side forks 15, the two ends of the detection component 2 are respectively fixedly connected with an in-situ switch 21 and an in-position switch 22, and a detection cursor 23 is installed on one side of one of the side forks 15 close to the detection component 2;

[0058] At the same time, when the connecting plate 19 moves forward, the piston rod provided on the connecting plate 19 slides outward from the piston cylinder 42 at the same time, so that the wash-free disinfectant in the liquid storage tank 41 enters the piston cylinder 42 through the hose. When the next pallet is lifted upward under the action of the jacking assembly 5, the connecting plate 19 drives the two side forks 15 to reset. At the same time, the piston rod slides toward the inside of the piston cylinder 42 under the action of the connecting plate 19, and the wash-free disinfectant in the piston cylinder 42 is pumped into the pressure tank 43 through the connecting pipe, and sprayed on the next pallet through the nozzle 44 to disinfect the pallet;

[0059] At the same time, when the connecting plate 19 moves, the two swinging plates 14 are driven to slide in the sliding groove on the connecting plate 19 in a direction close to each other. When the two swinging plates 14 slide, the moving racks 45 provided on the two swinging plates 14 simultaneously rotate the adjusting gear 46, thereby driving the pressurized tank 43 to rotate, causing the nozzle 44 to swing once, so that the spraying range of the nozzle 44 is greatly increased, ensuring that the entire tray is disinfected;

[0060] When the connecting plate 19 drives the side fork 15 to move forward or backward to fix the pallet, the detection cursor 23 installed on one side of the side fork 15 moves with the side fork 15 at the same time. In the initial position, the detection cursor 23 abuts against the in-situ switch 21. When the side fork 15 moves forward, the detection cursor 23 abuts against the in-place switch 22. Through the set in-situ switch 21 and detection cursor 23, within the set time, when the in-situ switch 21 or the in-place switch 22 fails to detect the detection cursor 23, the control part will give an alarm to remind the staff that the side fork 15 is not in place, so that the staff can carry out maintenance in time to avoid affecting the subsequent work.

[0061] Example 4, please refer to Figure 1-16 The lifting machine assembly 5 includes a lifting frame 51, both ends of the lifting frame 51 are equipped with eccentric push rods 52, and impact rods 53 are installed directly below the two eccentric push rods 52. The power assembly 6 includes a driving motor 61, and the output end of the driving motor 61 is fixedly connected to a rotating shaft through a coupling. Two transmission sprockets 63 are rotatably connected to the rotating shaft. The two transmission sprockets 63 are fixedly connected to a lifting rotary shaft 62. Main eccentric wheels 9 are installed on both ends of the two lifting rotary shafts 62, and one of the lifting rotary shafts A jacking position detection assembly is also provided on 62, and the jacking position detection assembly includes a plurality of evenly distributed detection pieces 64, and the plurality of detection pieces 64 are all installed on the jacking rotary shaft 62. A fixed seat is also provided on one side of the jacking rotary shaft 62, and a plurality of detection switches 65 are installed on the fixed seat, and each detection switch 65 corresponds to an adjacent detection piece 64, wherein the two main eccentric wheels 9 are installed with an eccentric wheel striker 91 at the limit output end away from the power assembly 6, and the eccentric wheel striker 91 contacts the adjacent limit swing rod 78 to block The assembly 7 includes a blocking plate 71, which is arranged just above the lifting machine assembly 5. The two ends of the bottom of the blocking plate 71 are respectively installed with blocking sleeves 72. The two blocking sleeves 72 are slidably connected to the lifting frame 51. The bottoms of the two blocking sleeves 72 are hinged with blocking swing rods 73. The two blocking swing rods 73 are installed with impact rollers 74. A blocking rod 75 is also arranged between the two blocking sleeves 72, and the two ends of the blocking rod 75 are respectively fixed to one end of the two blocking sleeves 72 close to the bottom. The blocking assembly 7 also includes The limiting plate 76 is provided between two adjacent blocking sleeves 72, and both ends of the limiting plate 76 are fixed to the lifting frame 51, and the limiting plate 76 is fixedly connected to the limiting rotating shaft 77, and both ends of the limiting rotating shaft 77 penetrate the limiting plate 76 and extend to both sides of the limiting plate 76, and the limiting rotating shaft 77 is rotatably connected to the limiting swing rod 78 on one end close to the power assembly 6, and the limiting swing rod 78 is installed on the side close to the bottom of the limiting swing rod 78. The limiting rotating shaft 79 abuts against the surface of the blocking rod 75;

[0062] When in use, firstly, the entire lifting machine assembly 5 is lifted by the lifting frame 51 to lift and stack the pallets. When the direction of the pallets entering and exiting needs to be adjusted, the drive motor 61 is started to adjust the position of the main eccentric wheel 9 by the drive motor 61. The main eccentric wheel 9 is provided with 6 positions (see Figure 11-Figure 16 ), through the setting of 6 workstations, the tray can be put in and out in multiple directions, which is convenient for use;

[0063] The first station is a low position. When the main eccentric wheel 9 rotates to this station, one end of the main eccentric wheel 9 abuts against the eccentric push rod 52, so that the lifting frame 51 cannot move upward. At the same time, the impact rod 53 presses the blocking assembly 7, so that the blocking assemblies 7 at both ends always keep a low position. The highest points of the two blocking assemblies 7 are lower than the conveying surface of the conveyor 8, so that the pallet can pass smoothly when transporting materials.

[0064] When the main eccentric wheel 9 needs to be adjusted to the second station, it needs to be rotated clockwise, and when the main eccentric wheel 9 needs to be adjusted to the third station, it needs to be rotated counterclockwise. When the main eccentric wheel 9 rotates clockwise to the second station, the eccentric wheel striker 91 on one side abuts against the limit swing rod 78 under the action of the rotation of the main eccentric wheel 9, so that the limit swing rod 78 rotates along the limit rotation shaft 77, so that the limit rotation shaft 79 abuts against the blocking rod 75. When the lifting frame 51 is lifted upward, under the pressure of the limit rotation shaft 79, the blocking plate 71 on this side cannot move up with the lifting frame 51 at the same time, and the blocking plate 71 on the other side does not follow the lifting frame 51 to move upward without the limit of the limit rotation shaft 79, so that the blocking plate 71 on this side is in a blocking state. At this time, the pallet can only enter and exit from the low side. The adjustment principle of station three is the same as that of station two, but the lifting side is opposite, which will not be described here.

[0065] Stations 4 and 5 are both in the middle-high position. When the main eccentric wheel 9 rotates to this position, the blocking plates 71 on both sides are not limited by the limiting rotating shaft 79 and can rise at the same time. Therefore, the pallet cannot continue to move from the conveyor line at this time.

[0066] Station six is ​​the high position. When the main eccentric wheel 9 is adjusted to this position, the lifting height of the lifting frame 51 is kept level with the top of the fixed plate 13.

[0067] When stacking pallets, first adjust the main eccentric wheel 9 to the second or third station according to the pallet in and out direction, convey the pallet to the lifting frame 51 through the conveyor 8, stop the pallet on the lifting frame 51 under the blockage of the blocking plate 71, turn off the conveyor 8, start the lifting frame 51, so that the lifting frame 51 drives the pallet to lift upward, and start the drive motor 61 at the same time, adjust the position of the main eccentric wheel 9, so that the lifting frame 51 drives the pallet to move upward to the sixth station, start the in and out motor 16, extend multiple side forks 15 outward to fix the pallet, and after fixing it, The main eccentric wheel 9 is adjusted to the station one, so that the lifting frame 51 is lowered and reset, and the next stacking is carried out. After the next pallet is conveyed to the lifting frame 51 by the conveyor 8, the main eccentric wheel 9 is adjusted to the station four or station five, so that the lifting frame 51 moves upward to just below the previous pallet. At this time, the in-out motor 16 is started to reset the multiple side forks 15. At the same time, the lifting frame 51 is started again and the main eccentric wheel 9 is adjusted to move the main eccentric wheel 9 to the station six. The in-out motor 16 is started to extend the multiple side forks 15 and insert them into the pallet to fix the pallet. The pallet stacking is achieved by repeating the operation continuously.

[0068] When it is necessary to dismantle the pallets, firstly, a pile of pallets are transported to the lifting frame 51 through the conveyor 8, the main eccentric wheel 9 is adjusted to the fourth or fifth station, so that the lifting frame 51 drives the pallet to rise, the in-and-out motor 16 is started to extend the multiple side forks 15, and the multiple side forks 15 are inserted into the second-to-last pallet, and then the main eccentric wheel 9 is adjusted to the first station, so that the lifting frame 51 is lowered, and at the same time, the lowermost pallet is separated from the second-to-last pallet and falls on the lifting frame 51, and then the lifting frame 51 is synchronously lowered, and after the dismantled pallet is transported out, the main eccentric wheel 9 is adjusted to the sixth station again, so that the lifting frame 51 moves up and contacts the pallet, and at the same time, the multiple side forks 15 are retracted by starting the in-and-out motor 16, and the main eccentric wheel 9 is adjusted to the fourth or fifth station, and the in-and-out motor 16 is started again to extend the multiple side forks 15, so that the multiple side forks 15 are inserted into the second-to-last pallet, and the lifting frame 51 is lowered again for splitting, and the above operation is repeated to carry out the dismantling work;

[0069] By means of the detection frame arranged on the frame body 10, the position of the pallet can be detected through the detection frame during the unpacking work to ensure that the unpacking work is accurate. At the same time, the multiple detection plates 64 and the multiple detection switches 65 arranged on the power assembly 6 correspond to the six workstations respectively. By means of the setting of the detection plates 64 and the detection switches 65, when the main eccentric wheel 9 workstation is adjusted, the adjustment accuracy can be detected through the detection plates 64 and the detection switches 65 to ensure the accuracy of each adjustment.

[0070] The working principle of the present invention is as follows: when the device is needed, the lifting machine assembly 5 and the two stacking tray frame assemblies 1 are first installed on the frame body 10. After they are fixed, the main eccentric wheel 9 is adjusted to the second or third station according to the in-and-out direction of the pallet, and the pallet is transported to the lifting frame 51 by the conveyor 8. The pallet is stopped on the lifting frame 51 under the blocking of the blocking plate 71, the conveyor 8 is closed, the lifting frame 51 is started, and the lifting frame 51 drives the pallet to lift upward, and at the same time, the driving motor 61 is started, and the position of the main eccentric wheel 9 is adjusted, so that the lifting frame 51 drives the pallet to move upward to the sixth station, and the conveyor 8 is turned off. By starting the in-and-out motor 16, the multiple side forks 15 are extended outward to fix the pallet. After fixing, the main eccentric wheel 9 is adjusted to the first station, so that the lifting frame 51 is lowered and reset, and the next stacking is carried out. After the next pallet is transported to the lifting frame 51 by the conveyor 8, the main eccentric wheel 9 is adjusted to the fourth or fifth station, and the lifting frame 51 moves upward. At this time, the in-and-out motor 16 is started to reset the multiple side forks 15, and the main eccentric wheel 9 is adjusted to move to the sixth station again. The in-and-out motor 16 is started to extend the multiple side forks 15 and insert them into the pallet to fix the pallet. The pallet is stacked by repeating the operation continuously;

[0071] When the in-and-out motor 16 is started, the in-and-out motor 16 drives the transmission belt to rotate, so that the transmission belt drives the connecting plate 19 to move. When the connecting plate 19 moves outward, the swing plates 14 arranged at both ends of the connecting plate 19 slide along the sliding grooves on the connecting plate 19. Under the action of the thrust of the connecting plate 19, the two swing plates 14 rotate along the sliding grooves, and the driving gears 31 arranged at the other ends of the two swing plates 14 rotate under the action of the swing plates 14. When the driving gear 31 rotates, the driven gear 32 meshing with the driving gear 31 rotates synchronously, and the rocker 34 connected to the driven gear 32 moves outward under the action of the driven gear 32, and at the same time pushes the connecting rod 33 to move outward, so that the horizontal roller 18 rotates under the drive of the horizontal plate 35, and the pallet is shaped by the horizontal roller 18. Through the setting of multiple side rollers 12 and the horizontal roller 18, the horizontal and side adjustments of the pallet are achieved to ensure that the pallet is stacked neatly;

[0072] At the same time, when the connecting plate 19 moves forward, the piston rod arranged on the connecting plate 19 slides outward from the piston cylinder 42 at the same time, so that the wash-free disinfectant in the liquid storage tank 41 enters the piston cylinder 42 through the hose. When the next pallet is lifted upward under the action of the lifting machine assembly 5, the connecting plate 19 drives the two side forks 15 to reset. At the same time, the piston rod slides toward the inside of the piston cylinder 42 under the action of the connecting plate 19, and the disinfectant in the piston cylinder 42 is pumped into the pressure tank 43 through the connecting pipe, and sprayed on the next pallet through the nozzle 44 to disinfect the pallet. When the connecting plate 19 moves, it drives the two swing plates 14 to slide in the sliding groove on the connecting plate 19 in a direction close to each other, and at the same time makes the adjusting gear 46 rotate, thereby driving the pressure tank 43 to rotate and driving the nozzle 44 to swing once, so that the spraying range of the nozzle 44 is greatly increased, ensuring that the entire pallet is disinfected;

[0073] When it is necessary to remove the pallet, first, a pile of pallets are transported to the lifting frame 51 through the conveyor 8, the main eccentric wheel 9 is adjusted to the station four or five, so that the lifting frame 51 drives the pallet to rise, the in-and-out motor 16 is started, and multiple side forks 15 are inserted into the second-to-last pallet, and then the main eccentric wheel 9 is adjusted to the station one, so that the lifting frame 51 descends, the bottom pallet is separated from the second-to-last pallet, and falls on the lifting frame 51, and then descends synchronously with the lifting frame 51. After the removed pallet is transported out, the main eccentric wheel 9 is adjusted to the station six again, so that the lifting frame 51 moves up and contacts the pallet, and at the same time, the multiple side forks 15 are retracted by starting the in-and-out motor 16, the main eccentric wheel 9 is adjusted to the station four or station five, and the in-and-out motor 16 is started again to extend multiple side forks 15, so that multiple side forks 15 are inserted into the current second-to-last pallet, and the lifting frame 51 is lowered again for splitting, and the above operations are repeated to remove the pallet.
