Description

Technical Field

[0001] This invention relates to the field of material conveying, specifically to a reversing transfer pallet conveyor line. Background Technology

[0002] Pallet conveyor lines are mainly used for transporting and transferring small items in warehousing and logistics, manufacturing, food processing, pharmaceuticals, and other industries.

[0003] In large transfer factories, pallet conveyor lines often undergo vertical docking to change the direction of pallet transport. The existing method for changing pallet transport involves lifting the pallet using a lifting structure, adjusting its orientation, and then using a transmission structure above the lifting structure to move the pallet to another conveyor line. While this method of changing pallet transport is stable, the reversing process is slow. Furthermore, during the reversing process, the previous pallet conveyor line needs to be stopped to prevent the pallet from getting stuck between the previous pallet conveyor line and the lifting structure. Therefore, the transfer efficiency of the existing pallet conveyor line's reversing function is low. Summary of the Invention

[0004] The purpose of this invention is to provide a reversing transfer pallet conveyor line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reversing transfer pallet conveyor line, comprising: a first conveyor line and a second conveyor line, and a pallet erected above the first conveyor line or the second conveyor line. The first conveyor line and the second conveyor line are vertically connected and arranged together. A reversing docking frame is fixedly erected between the first conveyor line and the second conveyor line, and the reversing docking frame is located at the docking point of the first conveyor line and the second conveyor line. The first conveyor line conveys the pallet toward the reversing docking frame, while the second conveyor line conveys the pallet away from the reversing docking frame.

[0009] A switching unit is used to switch the position states of the first conveying unit and the second conveying unit;

[0010] A partition unit is used to temporarily isolate the tray that has been moved above the reversing docking frame.

[0011] Preferably, the second conveying unit includes several second rotating shafts distributed equidistantly in a straight line, and the second rotating shafts movably pass through the reversing docking frame. The second rotating shafts are perpendicular to the first conveying line, and several second conveying wheels distributed equidistantly in a straight line are fixedly fitted on the outer surface of each second rotating shaft.

A first sprocket is fixedly fitted on the outer surface of each second rotating shaft, and a first chain is fitted on the external drive of several first sprockets. The first sprockets and the first chains are distributed inside the second straight frame. A second motor is also fixedly mounted on the outside of the second straight frame, and the output end of the second motor is fixed to the end of one of the second rotating shafts. The second motor causes the several second rotating shafts to rotate with the second conveying wheels through the action of the first sprockets and the first chain.

[0012] Preferably, the first conveying unit includes a plurality of first rotating shafts distributed equidistantly in a straight line, and the first rotating shafts movably pass through the reversing docking frame. The first rotating shafts are perpendicular to the second conveying line, and a plurality of first conveying wheels distributed equidistantly in a straight line are fixedly arranged on the surface of each first rotating shaft. A first straight frame is axially slidably mounted on the end of the reversing docking frame away from the first conveying line, and the first rotating shafts are rotatably embedded inside the first straight frame. A second sprocket is fixedly fitted on the outer surface of each first rotating shaft, and a second chain is externally driven by a plurality of second sprockets. The second sprockets and the second chains are both located inside the first straight frame. A first motor is also fixedly arranged on the outside of the first straight frame, and the output end of the first motor is fixedly docked with one of the first rotating shafts. The first motor can drive the plurality of first rotating shafts to rotate with the first conveying wheels through the action of the second sprockets and the second chains.

[0013] Preferably, the outer diameter of the first conveyor wheel is smaller than that of the second conveyor wheel, and the first rotating shaft is located above the second rotating shaft. The second conveyor wheels are distributed between two adjacent first rotating shafts, that is, the radius of the second conveyor wheel is larger, which allows the first rotating shaft to have a small vertical adjustment space.

[0014] Preferably, the switching unit includes two second sealing cylinders located below the first straight frame and the second straight frame. Both second sealing cylinders are fixedly assembled with the reversing docking frame. The upper and lower ends of the second sealing cylinders are open and closed, respectively. A second piston is slidably embedded inside the second sealing cylinder. A connecting rod is fixedly provided between the top of the two second pistons and the bottom of the first straight frame and the second straight frame, respectively. A spring is movably sleeved on the outside of the connecting rod, and the two ends of the spring are fixed to the second piston and the second sealing cylinder, respectively. An actuating component is also provided between the two second sealing cylinders. Depending on the amount of medium between the bottom of the second piston and the second sealing cylinder, the second piston can be finely adjusted up and down by the connecting rod along with the first straight frame and the second straight frame.

[0015] Preferably, the actuating component includes a first sealing cylinder located between the two second sealing cylinders. The first sealing cylinder is fixed to the outer wall of the reversing docking frame. A first piston is slidably embedded inside the first sealing cylinder, and an optical axis that slides through the first sealing cylinder is fixedly arranged inside the first piston. A first through pipe and a second through pipe are respectively fixedly connected between the two second sealing cylinders and the first sealing cylinder. The docking ports of the first through pipe and the second through pipe with the second sealing cylinder are located below the second piston. The docking ports of the first through pipe and the second through pipe with the first sealing cylinder are distributed vertically, and the first piston is located between the two ports. An electric push rod is also fixedly mounted on the top of the reversing docking frame, and the output end of the electric push rod is fixed to the optical axis. Each time the position of the first piston changes, the position of the two second pistons will change accordingly, and the adjustment directions of the positions of the two second pistons are opposite.

[0016] Preferably, the medium inside the second sealing cylinder, the first through pipe, the second through pipe, and the first sealing cylinder is a liquid or a gas. Liquids are not easily compressed and have better pressure-bearing effect, while gases are easily compressed and are not suitable for bearing the weight of products with large mass.

[0017] Preferably, the partition unit includes a sliding plate located below the first rotating shaft and the second rotating shaft, and a plurality of push rods are fixedly arranged on the top of the sliding plate in a straight line at equal intervals. The push rods are distributed between adjacent second conveying wheels and first conveying wheels. A driving component is also provided between the sliding plate and the optical shaft. When the sliding plate can move upward with the push rods, it can separate the trays that are close to each other.

A rack is fixedly mounted at the bottom of the optical shaft, and the rack meshes movably with the transmission gear. A limiting sleeve is axially slidably fitted on the outside of the sliding plate, and the limiting sleeve is fixed on the inner side of the reversing docking frame. An arc-shaped through groove is formed inside the limiting sleeve, and a straight groove is formed inside the sliding plate. The output end of the gear differential faces the limiting sleeve, and a transmission shaft is fixedly mounted at the output end of the gear differential. The transmission shaft is rotatably mounted on the end face of the limiting sleeve, and a turntable is fixedly fitted on the outer surface of the transmission shaft. A column is fixedly inserted inside the turntable, and the column simultaneously slides and embeds itself inside the arc-shaped through groove and the straight groove. Each time the optical shaft reciprocates, the gear differential is activated by the meshing of the rack and the transmission gear, causing the transmission shaft to rotate with the turntable. At this time, the column can lift the sliding plate.

[0019] Preferably, the bottom outer surface of the tray is provided with a chamfer, the top of the push rod is in the shape of an oblique arc, and the oblique arc end face of the push rod faces the first conveyor line. The chamfer design makes it easier to separate the two close trays when the push rod moves upward.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention assembles a first conveying unit and a second conveying unit inside the reversing docking frame, and through the adjustment of the switching unit, can quickly switch the states of the first conveying unit and the second conveying unit, thereby performing reversing and transfer processing on the pallets moved above the reversing docking frame. Moreover, under the action of the partition unit, the pallets above the reversing docking frame can be temporarily separated, thereby preventing the first conveyor line from continuously conveying other pallets toward the reversing docking frame during the reversing and transfer of the pallets above the reversing docking frame, thus avoiding jamming. At the same time, it can also achieve the goal of not frequently pausing the conveying operation of the first conveyor line. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-6The diagram shows a reversing transfer pallet conveyor line, comprising: a first conveyor line 1 and a second conveyor line 2, and a pallet 4 erected above the first conveyor line 1 or the second conveyor line 2. The first conveyor line 1 and the second conveyor line 2 are vertically connected. A reversing docking frame 3 is fixedly erected between the first conveyor line 1 and the second conveyor line 2, and the reversing docking frame 3 is located at the docking point of the first conveyor line 1 and the second conveyor line 2. The first conveyor line 1 conveys the pallet 4 toward the reversing docking frame 3, while the second conveyor line 2 conveys the pallet 4 away from the reversing docking frame 3.

[0034] It also includes: a second conveying unit, which has the same conveying direction as the first conveying line 1;

[0035] The first conveying unit is in the same conveying direction as the second conveying line 2;

[0036] Both the first conveying unit and the second conveying unit are located inside the reversing docking frame 3;

[0037] A switching unit is used to switch the position status of the first conveying unit and the second conveying unit.

[0038] The partition unit serves to temporarily isolate the tray 4 that has been moved above the reversing docking frame 3.

[0039] The second conveying unit includes several second rotating shafts 7 arranged in a straight line at equal intervals. The second rotating shafts 7 movably pass through the reversing docking frame 3. The second rotating shafts 7 are perpendicular to the first conveying line 1. Several second conveying wheels 8 arranged in a straight line at equal intervals are fixedly fitted on the outer surface of each second rotating shaft 7. A second straight frame 10 is axially slidably fitted on the end face of the reversing docking frame 3 away from the second conveying line 2. The ends of the second rotating shafts 7 are rotatably embedded inside the second straight frame 10. A first sprocket is fixedly fitted on the outer surface of each second rotating shaft 7. A first chain is fitted on the external drive of several first sprockets. The first sprockets and the first chain are distributed inside the second straight frame 10. A second motor 12 is also fixedly mounted on the outside of the second straight frame 10. The output end of the second motor 12 is fixed to the end of one of the second rotating shafts 7. The second motor 12 causes several second rotating shafts 7 to rotate with the second conveying wheels 8 through the action of the first sprockets and the first chain.

[0040] The first conveying unit includes several first rotating shafts 5 arranged in a straight line at equal intervals. The first rotating shafts 5 movably pass through the reversing docking frame 3. The first rotating shafts 5 are perpendicular to the second conveying line 2. Several first conveying wheels 6 are fixedly arranged in a straight line at equal intervals on the surface of each first rotating shaft 5. The end of the reversing docking frame 3 away from the first conveying line 1 is axially slidably fitted with a first straight frame 9. The first rotating shafts 5 are rotatably embedded inside the first straight frame 9. A second sprocket is fixedly fitted on the outer surface of each first rotating shaft 5. A second chain is externally driven by several second sprockets. The second sprockets and the second chain are both located inside the first straight frame 9. A first motor 11 is also fixedly installed outside the first straight frame 9. The output end of the first motor 11 is fixedly docked with one of the first rotating shafts 5. The first motor 11 can drive several first rotating shafts 5 to rotate with the first conveying wheels 6 through the action of the second sprockets and the second chain.

[0041] The outer diameter of the first conveyor wheel 6 is smaller than that of the second conveyor wheel 8, and the first rotating shaft 5 is located above the second rotating shaft 7. The second conveyor wheel 8 is distributed between two adjacent first rotating shafts 5, that is, the radius of the second conveyor wheel 8 is larger, which allows the first rotating shaft 5 to have a small vertical adjustment space.

[0042] The switching unit includes two second sealing cylinders 20 located below the first straight frame 9 and the second straight frame 10. Both second sealing cylinders 20 are fixedly assembled with the reversing docking frame 3. The upper and lower ends of the second sealing cylinders 20 are open and closed, respectively. A second piston 21 is slidably embedded inside the second sealing cylinder 20. A connecting rod 23 is fixedly arranged between the top of the two second pistons 21 and the bottom of the first straight frame 9 and the second straight frame 10, respectively. A spring 22 is movably sleeved on the outside of the connecting rod 23. The two ends of the spring 22 are fixed to the second piston 21 and the second sealing cylinder 20, respectively. An actuating component is also provided between the two second sealing cylinders 20. Depending on the amount of medium between the bottom of the second piston 21 and the second sealing cylinder 20, the second piston 21 can be finely adjusted up and down with the first straight frame 9 and the second straight frame 10 through the connecting rod 23.

[0043] The triggering component includes a first sealing cylinder 15 located between two second sealing cylinders 20. The first sealing cylinder 15 is fixed to the outer wall of the reversing docking frame 3. A first piston 16 is slidably embedded inside the first sealing cylinder 15, and an optical axis 14 that slides through the first sealing cylinder 15 is fixedly arranged inside the first piston 16. A first through pipe 18 and a second through pipe 19 are respectively fixedly connected between the two second sealing cylinders 20 and the first sealing cylinder 15. The docking ports of the first through pipe 18 and the second through pipe 19 with the second sealing cylinder 20 are located below the second piston 21. The docking ports of the first through pipe 18 and the second through pipe 19 with the first sealing cylinder 15 are distributed vertically, and the first piston 16 is located between the two ports. An electric push rod 13 is also fixedly mounted on the top of the reversing docking frame 3, and the output end of the electric push rod 13 is fixed to the optical axis 14. Each time the position of the first piston 16 changes, the position of the two second pistons 21 will change accordingly, and the adjustment direction of the position of the two second pistons 21 is opposite.

[0044] The medium inside the second sealing cylinder 20, the first through pipe 18, the second through pipe 19, and the first sealing cylinder 15 is either liquid or gas. Liquid is not easily compressed and has a better pressure-bearing effect, while gas is easily compressed and is not suitable for bearing the weight of products with large mass.

[0045] Working principle: In this scheme, a trigger module 33 is also fixedly installed at the end of the reversing docking frame 3, and its position distribution is shown in the attached figure. Figure 2 As shown, the function of the trigger module 33 is to activate the trigger module 33 when the tray 4 is transported above the reversing docking frame 3 and abuts against the inner wall of the reversing docking frame 3. The trigger module 33 can drive the electric push rod 13 to move the optical axis 14 back and forth once.

[0046] The first motor 11 and the second motor 12 are always running. In the initial state, the second rotating shaft 7 is in the raised state with the second conveyor wheel 8, and the upper horizontal cross-section of several second conveyor wheels 8 is at the same level as the contact surface of the first conveyor line 1 for transporting the pallet 4. That is, the first conveyor line 1 can seamlessly connect and transport the pallet 4 to the top of several second conveyor wheels 8 inside the reversing docking frame 3. When the pallet 4 touches the trigger module 33, the output end of the electric push rod 13 moves upward with the optical shaft 14 and then resets downward. During the upward movement, the medium inside the second sealing cylinder 20 located below the second straight frame 10 will be drawn into the interior of the first sealing cylinder 15. At this time, under the action of the spring 22, the connecting rod 23 will move the second straight frame 10 downward by a distance, that is, the second rotating shaft 7 and the second conveyor wheel 8 drop slightly.

[0047] When the first piston 16 moves upward, it will transport the medium above it through the first pipe 18 into the second sealing cylinder 20 located below the first straight frame 9. At this time, the second piston 21 located inside the second sealing cylinder 20 will rise and lift the first straight frame 9 through the connecting rod 23, that is, the first rotating shaft 5 and the first conveying wheel 6 will rise slightly.

[0048] By replacing the position of the second conveyor wheel 8 with the first conveyor wheel 6, the bottom of the pallet 4 located above the reversing docking frame 3 only contacts the first conveyor wheel 6 and not the second conveyor wheel 8. Driven by the first motor 11, the pallet 4 can be transferred to the second conveyor line 2 by the first conveyor wheel 6, thus completing the reversing and transfer operation of the pallet 4.

[0049] In this solution, the reversing docking frame 3 has a small footprint, making it more suitable for reversing and transferring in small spaces. It also provides high stability for reversing and transferring the pallet 4, preventing fluctuations in the pallet 4 and thus ensuring the stability of the products inside the pallet 4.

[0050] It is worth noting that the time it takes for the electric push rod 13 to reciprocate once each time the trigger module 33 is touched is sufficient to complete the reversing and transfer of the tray 4.

[0051] Example 2: Please refer to Figures 7-9 This embodiment is a further description of Embodiment 1. The partition unit includes a sliding plate 27 located below the first rotating shaft 5 and the second rotating shaft 7. Several push rods 28 are fixedly arranged in a straight line at equal intervals on the top of the sliding plate 27. The push rods 28 are distributed between the adjacent second conveying wheel 8 and the first conveying wheel 6. A driving component is also provided between the sliding plate 27 and the optical shaft 14. When the sliding plate 27 can move upward with the push rods 28, it can separate the trays 4 that are close to each other.

[0052] The drive components include a gear differential 24 fixedly mounted at the bottom of the reversing docking frame 3, with a transmission gear 25 fixedly fitted at the input end of the gear differential 24. A rack 17 is fixedly mounted at the bottom of the optical shaft 14, and the rack 17 is movably meshed with the transmission gear 25. A limiting sleeve 26 is axially slidably fitted on the outside of the sliding plate 27, and the limiting sleeve 26 is fixed on the inner side of the reversing docking frame 3. An arc-shaped through groove 31 is formed inside the limiting sleeve 26, and a straight groove 32 is formed inside the sliding plate 27. The output end of the gear differential 24 faces the limiting sleeve 26. Furthermore, a drive shaft 35 is fixedly installed at the output end of the gear differential 24. The drive shaft 35 is rotatably mounted on the end face of the limiting sleeve 26. A turntable 29 is also fixedly fitted on the outer surface of the drive shaft 35. A column 30 is fixedly inserted inside the turntable 29. The column 30 is simultaneously movably slidably embedded in the arc-shaped through groove 31 and the straight groove 32. Each time the optical shaft 14 moves back and forth, it can activate the gear differential 24 through the meshing of the rack 17 and the drive gear 25, thereby causing the drive shaft 35 to rotate with the turntable 29. At this time, the column 30 can lift the sliding plate 27.

[0053] The bottom outer surface of the tray 4 is provided with a chamfered part 34, the top of the push rod 28 is in the shape of an oblique arc, and the oblique arc end face of the push rod 28 faces the first conveyor line 1. The design of the chamfered part 34 makes it easier to separate the two close trays 4 when the push rod 28 moves upward.

[0054] In this embodiment: when the optical axis 14 starts to move upward, the gear differential 24 can be activated by the action of the rack 17 and the transmission gear 25, so that the transmission shaft 35 rotates the turntable 29. The column 30 is eccentrically set inside the turntable 29. When the turntable 29 rotates at a certain angle, the column 30 can lift the sliding plate 27 by the action of the straight groove 32. It should be noted that the turntable 29 and the arc groove 31 are coaxially distributed. The arc groove 31 can ensure the stability of the movement of the column 30.

[0055] As the first conveyor line 1 continues to operate, when the first pallet 4 comes into contact with the inner wall of the reversing docking frame 3, the second pallet 4 will be in close contact with the first pallet 4. When the sliding plate 27 moves upward, the push rod 28 pushes the chamfered part 34 at the bottom of the pallet 4, which can separate the second pallet 4 from the first pallet 4, thus providing temporary isolation for the first pallet 4.

[0056] It should be noted that the rotational speed of the turntable 29 can be changed by the gear differential 24, so that the push rod 28 separates the first pallet 4 before the first conveyor wheel 6 contacts the bottom of the first pallet 4. This ensures that when the first pallet 4 is being reversed and transferred, the subsequent pallets 4 will not be squeezed by the operation of the first conveyor line 1, thus preventing the pallets 4 from getting stuck on the upper part of the reversing docking frame 3.

[0057] By using the partition unit, the tray 4 on the first conveyor line 1 can be transferred to the second conveyor line 2 without frequent shutdown operations.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
