Description

Technical Field

[0001] This application relates to the field of automated conveying, specifically to a conveying device for loading and unloading pallet jacks. Background Technology

[0002] Pallet jacks are a common type of transport vehicle, also known as pallet trucks or flatbed trucks. In automated conveyor systems, the movement of pallets is involved. This requires people to place the pallets on the pallet jack and push them to the designated location on the conveyor line. Because the pallet jack's conveying plane is very low and can usually only provide a small vertical displacement, after reaching the predetermined location on the conveyor line, the pallets need to be manually moved onto the conveyor line or lifted and placed onto the conveyor line using a special lifting forklift. This process is costly, time-consuming, and labor-intensive. Summary of the Invention

[0003] In view of the above reasons, this application discloses a conveying device for loading and unloading pallet jacks, including a lifting unit and a horizontal conveying unit. The lifting unit drives the horizontal conveying unit to move up and down in the vertical direction. The horizontal conveying unit includes a conveying line with a horizontal opening. When the conveying line is at its lowest position in the vertical direction, the opening can be used to accommodate the pallet jacks.

[0004] Preferably, the conveyor line includes short rollers on both sides, one end of which is connected to and synchronously driven by a long roller. The short rollers on both sides are horizontally spaced apart to form a horizontal opening away from the side of the long roller.

[0005] Preferably, the lifting unit includes a lifting bracket and a driving mechanism. The conveyor line is mounted on the lifting bracket via the driving mechanism and is displaced vertically relative to the lifting bracket under the drive of the driving mechanism.

[0006] Preferably, the lifting brackets are respectively disposed on both sides of the conveyor line, and the driving mechanism includes a driving belt, a driving wheel, a driven wheel, and a chain. The driving wheel and the driven wheel are respectively disposed at the upper and lower ends of the lifting bracket, and the chain is wound around the driving wheel and the driven wheel. The driving motor drives the driving wheel to rotate, thereby driving the chain to rotate and displace in the vertical direction.

[0007] Preferably, both sides of the conveyor line are connected to the chain on the opposite side via connecting frames, and the chain drives the conveyor line to move vertically up and down relative to the lifting bracket.

[0008] Preferably, the lifting bracket is provided with a linear track groove along the vertical direction, and the corresponding position of the connecting frame is provided with a sliding component, which slides in cooperation with the linear track groove.

[0009] Preferably, the sliding assembly includes a first pulley and a second pulley, both of which are connected to the linear track groove, and the rotation directions of the first pulley and the second pulley are horizontally orthogonal.

[0010] Preferably, a limiting baffle is provided between the short rollers on both sides, and the limiting baffle is detachably connected to the short rollers, limiting the maximum distance that the jackhammer can enter the opening.

[0011] Preferably, the limiting baffle is provided with a buffer block facing the opening direction of the opening.

[0012] Preferably, the lifting bracket is equipped with a high-position sensor and a low-position sensor. The high-position sensor is located at the highest position of the conveyor line on the lifting bracket, and the low-position sensor is located at the lowest position of the conveyor line on the lifting bracket. The detection signals generated by the high-position sensor and the low-position sensor control the operating state of the drive mechanism.

[0013] The advantage of this application is that it adopts a conveyor line with an open design, which, together with a lifting unit, can be connected to a pallet jack and lift the pallet carried by the pallet jack to the corresponding height. It can also be directly connected to an external conveyor system without the need for an additional power unit. The structure is simple and the operation is convenient.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions 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, 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.

[0024] like Figures 1 to 4As shown, the conveyor line 1 includes short roller lines 101 on both sides. One end of the short roller lines 101 on both sides is connected by a long roller 102. The long roller 102 plays the role of power transmission, that is, the power of the short roller line 101 on one side can be transmitted to the short roller line 101 on the other side through the long roller 102. The line motor only needs to be set on one side of the short roller line 101, which saves the driving cost and ensures that the conveying rhythm of the short roller lines 101 on both sides is the same. The short roller conveyors 101 and long rollers 102 on both sides form a U-shaped opening 103 with a horizontal opening. The opening width of the opening 103, i.e., the relative distance between the inner sides of the short roller conveyors 101 on both sides, should not be less than the outer distance of the ground jack 2 to ensure that the ground jack 2 can be moved horizontally into the opening 103. Under the drive of the lifting unit, the short roller conveyors 101 can move up and down in the vertical direction. When the short roller conveyors 101 are at their lowest position, their conveying plane height should be lower than the conveying plane height of the ground jack 2. At this time, the ground jack 2 can carry its... The pallet carried above enters the opening 103, and the short roller conveyors 101 on both sides are at least partially located vertically below the pallet. Then, the lifting unit drives the short roller conveyors 101 to move vertically upward. During the process, the short roller conveyors 101 contact the lower surface of the pallet and support the pallet to move vertically upward. When the pallet is lifted to the preset height, the short roller conveyors 101 connect to the external conveying system and horizontally transport the pallet to the external conveying system. At the same time, the pallet jack 2 can be removed. Then, the short roller conveyors 101 return to the lowest position and start the next round of operation.

[0025] In some implementations, such as Figures 1 to 4 As shown, the lifting unit includes a lifting bracket 3 and a driving mechanism. The lifting bracket 3 is a metal bracket with a certain vertical height and structural strength. The bottom end of the lifting bracket 3 is fixedly connected to the ground. The driving mechanism is set on the lifting bracket 3. The conveyor line 1 is connected to the lifting bracket 3 through the driving mechanism. The lifting state of the conveyor line 1 is controlled by controlling the running state of the driving mechanism.

[0026] In some implementations, such as Figures 1 to 4As shown, lifting brackets 3 are respectively arranged opposite to each other on both sides of the conveyor line 1, that is, on the outer side of the short roller line 101 on both sides. The lifting brackets 3 have slots in opposite directions. The drive wheel 4 and the driven wheel 5 are respectively arranged in the slots and are located at the upper and lower ends of the lifting brackets 3. The drive motor 6 is arranged on the drive wheel 4 on one side and drives the drive wheel 4 to rotate through the drive shaft. The drive wheels 4 in the slots of the lifting brackets 3 on both sides complete the power transmission through the transmission shaft 7. Specifically, the transmission can be completed by the cooperation of the bevel gear 8. The bevel gear 8 sets are orthogonally meshed in the horizontal direction to change the direction of force transmission. The chain 9 is sleeved between the drive wheel 4 and the driven wheel 5 on the same side. When the drive motor 6 drives the drive wheel 4 on this side to rotate, the chain 9 on both sides will be driven to rotate and displace synchronously in the vertical direction through the transmission shaft 7 and the drive wheel 4 on the corresponding side. By controlling the forward and reverse rotation of the drive motor 6 and the rotation speed, the upward and downward movement of the chain 9 and the movement speed of the chain 9 can be controlled. The drive motor 6 is located on one side, which saves on drive costs while ensuring the synchronicity of the movement of the chains 9 on both sides.

[0027] In some implementations, such as Figures 1 to 4 As shown, on both sides of the conveyor line 1, i.e. the opposite outer sides of the short roller line 101 on both sides, a connecting frame 10 is fixedly installed. The connecting frame 10 is connected to the chain 9 on its opposite side. Specifically, its upper end is hinged to one end of the chain 9, and its lower end is hinged to the other end of the chain 9. The chain 9 is in a tensioned state. When the chain 9 rotates, it will drive the connecting frame 10 to move up and down, and at the same time drive the conveyor line 1 to move up and down.

[0028] In some implementations, such as Figures 1 to 5 As shown, the lifting bracket 3 is provided with a vertical linear track groove 11, and the connecting frame 10 is provided with a pulley assembly at a relative position. The pulley assembly slides in cooperation with the linear track groove 11, playing an auxiliary guiding role. The sliding assembly includes a first pulley 12 and a second pulley 13. The rotation directions of the first pulley 12 and the second pulley 13 are horizontally orthogonal. The two ends of the outer surface of the first pulley 12 slide against the inner walls on both sides of the groove opening of the linear track groove 11. One end of the outer surface of the second pulley 13 slides against the inner wall on the side of the groove opening away from the groove opening of the linear track groove 11. The first pulley 12, the second pulley 13 and the linear track groove 11 form a limiting relationship. While providing auxiliary guidance through sliding cooperation, it can prevent the connecting frame 10 from making horizontal displacement relative to the lifting bracket 3. Multiple sets of the first pulley 12 and the second pulley 13 can be provided, depending on the length of the linear track groove 11, and there is no specific limitation.

[0029] In some implementations, such as Figures 1 to 4As shown, a vertically oriented limiting baffle 14 is provided between the short roller line bodies 101 on both sides. The limiting baffle 14 is detachably connected to the short roller line bodies 101 on both sides and its specific position can be adjusted. The limiting baffle 14 limits the maximum distance that the ground jack 2 can enter the opening 103 by contacting the front end of the ground jack 2, which can prevent the ground jack 2 from entering too deeply and causing contact and collision between the rear end and the short roller line body 101.

[0030] In some implementations, such as Figure 4 As shown, the limiting baffle 14 is provided with a buffer block 15 facing the opening of the opening 103. The buffer block 15 is used to contact the front end of the ground jack 2 and plays a buffering role to prevent the conveyor line from being subjected to large vibrations and reduce damage.

[0031] In some implementations, such as Figure 1 and Figure 5 As shown, the lifting support 3 is equipped with a high-position sensor 16 and a low-position sensor 17. The high-position sensor 16 is located at the highest position of the conveyor line 1 on the lifting support 3 and is used to detect whether the conveyor line 1 is at the highest position on the lifting support 3. The low-position sensor 17 is located at the lowest position of the conveyor line 1 on the lifting support 3, i.e., the lowest stroke, and is used to detect whether the position of the conveyor line 1 is at the lowest stroke. Based on the detected electrical signal, the drive motor 6 is controlled to stop when the highest and lowest positions are reached to prevent over-positioning during the lifting process.
