Description

Technical Field

[0001] This invention relates to the field of pallet loading equipment technology, specifically a fully automatic metering pallet loading device. Background Technology

[0002] Assembly line operations involve processing products one by one, and at the beginning of the line, there is an essential initial feeding station, commonly known as the line starter. At the line starter, frequent manual loading is required. Typically, workers pull a pallet containing the products to be processed, place them one by one at the line starter, and then collect the empty pallets and pull them away. This not only results in high labor intensity and worker fatigue, but also high production costs and low production efficiency.

[0003] Current pallet loading equipment still has some shortcomings: existing pallet loading equipment generally does not have a weighing and measurement process for materials during loading, resulting in inconsistent material weights in each pallet, which is not conducive to subsequent processes. Currently, manual intervention is required when loading and transferring materials to place the pallets at the receiving port and move them to the next process. This is labor-intensive, causes worker fatigue, and is inefficient.

[0004] The purpose of this invention is to provide a fully automatic metering pallet loading device to solve the problems mentioned in the background art. Summary of the Invention

An electric telescopic rod is provided at the end of the movable rod away from the reciprocating lead screw, and a suction cup is provided at the telescopic end of the electric telescopic rod for connecting to a tray.

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

[0021] 1. This invention includes a conveyor and a feeding mechanism. A drive motor drives a pulley assembly to rotate, causing a connecting rod symmetrically connected to the pulley assembly to rotate as well. At the same time, the support plate on the connecting rod rotates, causing the pallet on the middle plate of the support plate to fall onto the conveyor belt of the conveyor. Then, a cylinder pushes the centering plate to align the pallet. After alignment, the conveyor starts moving and transports the pallet to the second conveyor for the next operation. This design enables automated pallet pushing and reduces labor costs.

[0022] 2. This invention includes a second conveyor and a metering device. Pallets conveyed from the first conveyor fall onto the top plate of the metering device. Once the entire pallet is stably placed on it, the solenoid valve on the storage hopper is opened, allowing material to fall into the pallet. The material in the pallet is weighed by a sensor pressure head at the bottom of the top plate and a connected weighing sensor. When the required weight is reached, the solenoid valve on the storage hopper closes. Then, cylinder two in the pushing mechanism pushes the fixed plate, causing the electric push rod on it to move upward until the claw of the electric push rod aligns with the slot of the pallet. Cylinder two then closes, and the electric push rod pushes the claw towards the slot of the pallet. After the claw engages in the slot, it continues to push the pallet until it falls onto the conveyor belt of the second conveyor. The push rod retracts, separating the claw from the slot. Cylinder two then drives the electric push on the fixed plate to retract downward until the top is flush with the top plate. This design facilitates the weighing and metering of material on each pallet, ensuring consistent material weight across all pallets, which is beneficial for subsequent use.

[0023] 3. This invention is equipped with a positioning mechanism. A hydraulic cylinder pushes the connecting plate upward, and one end of the movable block fixedly connected to both ends of the connecting plate moves upward accordingly. At the same time, the clamping block connected to the other end of the movable block moves upward around the axis. The clamping post at the end of the clamping block separates from the top plate. At this time, the pallet can be sent onto the top plate. When the entire pallet is on the top plate, the hydraulic cylinder retracts, causing the movable block to push the clamping block downward around the axis with the bottom and the top edge of the arc groove as the base points. This causes the clamping post on the clamping block to move towards the pallet until the clamping post is in contact with the top of the pallet, thereby achieving the positioning and fixing of the pallet. The pressure applied by the clamping post to the pallet will not affect the weighing and measurement of the material. It only limits and fixes the pallet in the up, down, left, and right directions to prevent the pallet from shifting during material unloading.

[0024] 4. This invention is equipped with a feeding device. After the pallet has been metered, it is conveyed to the worktable of the feeding device via the conveyor belt of conveyor two. The electric telescopic rod on the movable rod pushes the suction cup to move towards the top of the pallet frame until the suction cup picks up the pallet. Then, the drive motor drives the drive pulley to rotate. The belt two connected to the drive pulley drives pulley one, pulley two, and pulley three to rotate in sequence. The rotation of pulley one and pulley three causes the reciprocating screw to rotate accordingly. The movable rod on the reciprocating screw moves horizontally along the reciprocating screw, thereby moving the pallet until it is moved to the desired position. After the pallet is moved, the electric telescopic rod drives the suction cup to detach from the pallet. Then, the reverse drive motor causes the movable rod to move back until it moves to the initial position. This design facilitates the transfer of the pallet to the next step for use without manual transfer, thus improving work efficiency. Attached Figure Description

[0047] The present invention will be further described in detail below with reference to the accompanying drawings.

[0048] Example 1:

[0049] Please see Figure 1-8 This invention provides a fully automatic metering pallet loading device, including a pallet 1, a material storage device, and a conveying device. The conveying device includes a first conveyor 4 and a second conveyor 6, which are connected to each other. The pallet 1 is mounted on the first conveyor 4 via a feeding mechanism. The material storage device is mounted on the second conveyor 6 and is located at one end where the first conveyor 4 and the second conveyor 6 are connected. The other end of the second conveyor 6 is connected to a feeding device.

[0050] The feeding mechanism is installed at one end of the conveyor 4. The feeding mechanism is provided with a plurality of the trays 1. The conveyor 4 is also provided with a centering mechanism, which is used to center and correct the trays 1.

[0051] The feeding mechanism includes a fixed frame 2, a support plate, and a driving mechanism. The fixed frame 2 is fixedly installed on the frame of the conveyor 4. The bottom of the fixed frame 2 is provided with four guide columns 201. The pallet 1 is movably installed between the four guide columns 201. The driving mechanism is located on the top of the fixed frame 2. The support plate is connected to the driving mechanism. The pallet 1 is movably connected to the support plate.

[0052] The driving mechanism includes a drive motor 202, a pulley assembly, and a connecting rod 3. The drive motor 202 is fixedly mounted on the fixed frame 2 and its output end is connected to the pulley assembly. The connecting rod 3 is symmetrically rotatably mounted on the fixed frame 2 and connected to the pulley assembly. The support plate is fixedly mounted on the connecting rod 3 and is positioned at the center below each pair of guide posts 201.

[0053] The pulley assembly includes a drive wheel 203, symmetrically mounted transmission wheels 204, 205, 206, and 207, and a belt 208. The drive wheel 203 is connected to the drive motor 202. The belt 208 starts from the drive wheel 203, passes sequentially around the transmission wheels 204, 205, and 306, then around the symmetrically mounted transmission wheels 206, 205, and 204, and finally passes around the belt 207 before closing with the belt 208 on the drive wheel 203. The connecting rod 3 is fixedly connected to the symmetrical transmission wheels 205.

[0054] The support plate includes a first plate 301 and a second plate 302. The first plate 301 and the second plate 302 are vertically installed on the connecting rod 3 and are arranged in a cross shape. There is a gap between the first plate 301 and the second plate 302. The bottom ends of the tray 1 are provided with n-shaped grooves 001, and the n-shaped grooves 001 are in contact with the top of the first plate 301.

[0055] The centering mechanism includes symmetrically installed cylinder 5 and centering plate 501. The symmetrically installed cylinder 5 is mounted on the frame of the conveyor 4. The telescopic end of the cylinder 5 is fixedly connected to the outer wall of the centering plate 501. The centering plate 501 is provided with an anti-slip pad 502 on the opposite side.

[0056] In use, the drive motor 202 drives the drive wheel 203 to rotate. Under the action of the belt 208, the transmission wheel 207 rotates accordingly. The symmetrically arranged transmission wheels 204, 206, and 205 rotate accordingly. At the same time, the connecting rod 3 connected to the transmission wheel 205 rotates. At this time, the support plates on the symmetrically arranged connecting rod 3 rotate simultaneously. When the support plates rotate, plate 301 disengages from the n-shaped groove 001 of the pallet 1, and plate 302 enters the n-shaped groove 001 of the next pallet 1. The pallet 1 that has disengaged from plate 301 falls onto the conveyor belt of the conveyor 4, and then... Cylinder 5 pushes the centering plate 501 to center and align the pallet 1. After alignment, conveyor 4 starts and transports the pallet 1 to conveyor 6 for the next operation. When another pallet 1 is placed down, simply rotate the connecting rod 3 to make the pallet 1 on plate 2 302 fall onto plate 1 301. After the previous pallet 1 is completely detached from conveyor 4, rotate the connecting rod 3 again to make the pallet 1 fall off plate 1 301. Repeat this operation to achieve automatic pallet 1 falling onto the conveyor belt of conveyor 4. In this embodiment, the width of the n-shaped grooves 001 on both sides of the pallet 1 is greater than the overall length of the supporting plate, allowing the supporting plate to move within the grooves.

[0057] Example 2:

[0058] Please refer to this carefully. Figure 4 , Figure 5 , Figure 7 The conveyor 6 is also equipped with a metering device, which includes a base 7, a top plate 701, a bottom plate 702, a load cell 703, and a sensor pressure head 704. The base 7 is installed between the frames at one end of the conveyor 6, the bottom plate 702 is installed on the base 7, the load cell 703 is installed on the bottom plate 702, and the sensor pressure head 704 is installed on the load cell 703. The sensor pressure head 704 is in contact with the bottom of the top plate 701. Multiple hollow columns 706 are fixedly installed at the bottom of the top plate 701. The bottom plate 702 is provided with guide rods 707 that cooperate with the hollow columns 706. A connecting plate 705 is installed between the hollow columns 706. The connecting plate 705 is provided with through holes. The weighing sensor 703 is installed in the through holes. The top of the top plate 701 is higher than the top of the conveyor belt on the second conveyor 6. The frame is also provided with a pushing mechanism, which is used to push the pallet 1 onto the conveyor belt on the second conveyor 6.

[0059] The pushing mechanism includes symmetrically installed cylinders 10, a fixed plate 101, and an electric push rod 102. The symmetrical cylinders 10 are fixedly installed on the base 7 and located at one end of the conveyor belt away from the conveyor 6. The bottom of the fixed plate 101 is fixedly connected to the telescopic end of the symmetrical cylinders 10. The electric push rod 102 is symmetrically installed on the top of the fixed plate 101. The telescopic end of the electric push rod 102 is fixedly connected to a claw 103. The outer wall of the tray 1 is provided with a groove 002 that cooperates with the claw 103.

[0060] The material storage device includes a mounting frame 8 and a storage bin 801. The mounting frame 8 is fixedly installed on the frame of the second conveyor 6.

The bottom of the storage bin 801 is provided with a discharge pipe 802, and a solenoid valve 803 is provided on the discharge pipe 802.

[0061] In use, the pallet 1 conveyed from conveyor 4 lands on the top plate 701 of the metering device. After the entire pallet 1 is stably placed on it, the solenoid valve 803 on the storage bin 801 is opened, allowing the material to fall into the pallet 1. The material in the pallet 1 is weighed and measured by the sensor pressure head 704 at the bottom of the top plate 701 and the connected weighing sensor 703. When the required weight is reached, the solenoid valve 803 on the storage bin 801 closes. Then, the cylinder 10 in the pushing mechanism pushes the fixed plate 101, causing the electric push rod 102 on it to move upward until the electric push rod... After the claw 103 of 102 aligns with the slot 002 of pallet 1, cylinder 2 10 closes, and electric push rod 102 pushes the claw 103 to move towards the slot 002 of pallet 1. After the claw 103 engages in the slot 002, it continues to push pallet 1 until pallet 1 falls onto the conveyor belt of conveyor 2 6. Then, the push rod retracts and the claw 103 separates from the slot 002. Cylinder 2 10 drives the electric push on the fixed plate 101 to retract downwards until the top is flush with the top plate 701. This design facilitates the weighing and measurement of the material on each pallet 1, ensuring that the material weight on each pallet 1 is consistent, which is beneficial for subsequent use.

[0062] Example 3:

[0063] Please refer to this carefully. Figure 4 , Figure 6 The metering device is also equipped with a positioning mechanism, which is located on both sides of the base plate 702 and is used to position and fix the pallet 1.

[0064] The positioning mechanism includes positioning posts 9, hydraulic cylinders 901, and clamping components. The positioning posts 9 are fixedly installed on the top two sides of the base plate 702. The hydraulic cylinders 901 are located near the positioning posts 9 and are fixedly connected to the base plate 702. The clamping components are installed on the symmetrical positioning posts 9. One end of the clamping component is fixedly connected to the telescopic end of the hydraulic cylinder 901. The clamping components are used to fix the tray 1.

[0065] The clamping component includes symmetrically installed clamping blocks 902 and movable blocks 903. A mounting plate 905 is provided on the positioning post 9. The clamping block 902 is movably installed on the mounting plate 905 and movably connected to one end of the movable block 903. An arc-shaped groove 907 is provided on the mounting plate 905. The end of the movable block 903 connected to the clamping block 902 is movably installed within the arc-shaped groove 907. The bottom of the movable block 903 contacts the top edge of the arc-shaped groove 907. A clamping post 908 is fixedly connected to the end of the clamping block 902 away from the movable block 903. A fixing rod 904 is fixedly connected between the symmetrical movable blocks 903. The fixing rod 904 is fixedly connected to the telescopic end of the hydraulic cylinder 901. Limiting plates 906 are movably connected to the outer walls on both sides of the movable block 903 within the arc-shaped groove 907. The end of the limiting plate 906 away from the movable block 903 is movably connected to the mounting plate 905.

[0066] In use, the hydraulic cylinder 901 pushes the connecting plate 705 upward, and one end of the movable block 903 fixedly connected to both ends of the connecting plate 705 moves upward accordingly. At the same time, the clamping block 902 connected to the other end of the movable block 903 moves upward around the axis, and the abutting post 908 at the end of the clamping block 902 separates from the top plate 701. At this time, the pallet 1 can be sent onto the top plate 701. When the entire pallet 1 is on the top plate 701, the hydraulic cylinder 901 retracts, causing the movable block 903 to push the clamping block 902 downward around the axis with the bottom and the top edge of the arc groove 907 as the base points. This causes the abutting post 908 on the clamping block 902 to move towards the pallet 1 until the abutting post 908 is in contact with the top of the pallet 1, thereby achieving the positioning and fixing of the pallet 1. The pressure applied by the abutting post 908 to the pallet 1 will not affect the weighing and measurement of the material. It only limits and fixes the pallet 1 in the up, down, left and right directions to prevent the pallet 1 from shifting during material unloading.

[0067] Example 4:

[0068] Please refer to this carefully. Figure 1 , Figure 8 The other end of the conveyor 6 is connected to a feeding device;

[0069] The feeding device includes a support 11, a worktable 111, and an execution device. The worktable 111 is mounted on the support 11, and the execution device is movably mounted on the support 11.

A second pulley 119 is also provided directly above the drive pulley 117, and is rotatably mounted on the outer wall of the bracket 11. 17 is connected to a second belt 121, which passes sequentially through a first pulley 118, a second pulley 119, a third pulley 120, and finally closes at the drive pulley 117. The transmission motor 113 is fixedly installed on the bracket 11 and located below the workbench 111. The movable rod 114 is connected to the reciprocating lead screw 112 by a thread. The end of the movable rod 114 away from the reciprocating lead screw 112 is provided with an electric telescopic rod 115. The telescopic end of the electric telescopic rod 115 is provided with a suction cup 116, which is used to connect to the tray 1.

[0071] In use, after the measurement is completed, the pallet 1 is conveyed to the workbench 111 of the feeding device via the conveyor belt of the second conveyor 6. The electric telescopic rod 115 on the movable rod 114 pushes the suction cup 116 to move towards the top of the pallet 1 frame until the suction cup 116 picks up the pallet 1. Then, the drive motor 113 drives the drive pulley 117 to rotate. The belt second 121 connected to the drive pulley 117 drives the pulley first 118, pulley second 119, and pulley third 120 to rotate in sequence. The rotation of pulley first 118 and pulley third 120 causes the reciprocating screw 112 to rotate accordingly. The movable rod 114 on the reciprocating screw 112 moves horizontally along the reciprocating screw 112, thereby moving the pallet 1 until it is moved to the desired position. Then, the electric telescopic rod 115 drives the suction cup 116 to be pulled away from the pallet 1. Then, the reverse drive motor 113 causes the movable rod 114 to move back until it moves to the initial position. This design facilitates the transfer of the pallet 1 to the next step for use.
