Description

Technical Field

[0001] This utility model relates to the field of coil transfer technology, specifically a novel pallet lifting device for an HL line conveyor system. Background Technology

[0002] In existing wire rod rolling processes, the pallet lifting device in the HL line conveyor system is mainly used to receive finished coils and transfer them to the conveyor line for further processing. Traditional pallet lifting devices typically consist of a slide, a lifting drive mechanism, and a coil clamping structure. The receiving and placement of the coils is achieved by the slide moving up and down along the column. However, existing devices have certain drawbacks:

[0003] In actual production, the weight of the coil is a crucial indicator for determining whether it meets process standards. However, traditional equipment cannot simultaneously complete the weighing operation during the coiling process, requiring secondary inspection by manual labor or independent weighing equipment. This not only increases process complexity and reduces efficiency but may also lead to data errors or coil damage due to secondary operations during handling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel pallet lifting device for an HL line conveyor system.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel pallet lifting device for an HL line conveyor system includes: a conventional pallet lifting seat and a slide. The conventional pallet lifting seat has a first column and a second column respectively arranged at the front and rear. The slide is mounted on the columns, and multiple sets of connecting rollers that roll in vertical contact with the first and second columns are arranged on the upper part of the slide. A first coil clamp and a second coil clamp are respectively arranged on the front and rear sides of the upper end of the slide. A rotating shaft is arranged at the connection between the coil clamp and the slide. The coil clamp is used to clamp the coil. A load-bearing plate is arranged on the left and right sides of the top of the first coil clamp, and a weighing sensor is arranged under the load-bearing plate.

[0007] The first and second roll clamps have the same structure, the load-bearing plate is used to support the roll, and the weighing sensor collects the weight of the roll.

[0008] Preferably, the top of the traditional slide lifting seat is equipped with multiple sets of sprockets, with chains wrapped around the sprockets. The other end of the chains is connected to the slide seat. A drag chain is provided on the chain. The sprockets are connected to the drive motor shaft to provide power for the lifting and lowering of the slide seat, and the drag chain is used to realize the lifting and lowering of the slide seat.

[0009] Preferably, cylinder one and cylinder two are respectively provided on the front and rear sides of the upper end face of the slide block. The shaft ends of the push rods of cylinder one and cylinder two are respectively hinged to the outer surfaces of the first and second roll clamps. The extension and retraction of the push rods of the cylinders control the clamping of the first and second roll clamps to clamp the coil.

[0010] Preferably, upper and lower buffer blocks are provided at the upper and lower ends of column one and column two, respectively, and the buffer blocks are used to offset the impact force generated when the slide is lifted and lowered.

[0011] Preferably, a hydraulic pipe is provided in the center of the slide, and the hydraulic pipe transmits pressure and power to cylinder one and cylinder two through hydraulic oil.

[0012] Compared with the prior art, this utility model provides a novel pallet lifting device for an HL line conveyor system, which has the following beneficial effects:

[0013] This invention achieves real-time and accurate detection of the weight of the coil by setting a weighing sensor in the pallet lifting device, which has certain technical advantages compared with the prior art. The weighing sensor is set below the load-bearing plate of the first pallet clamp. When the coil falls to the load-bearing plate, its weight is directly transferred to the weighing sensor through the load-bearing plate, without the need for additional transfer or weighing procedures.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 As shown in this embodiment, a novel pallet lifting device for an HL line conveyor system includes a conventional pallet lifting seat 13. A first column 801 and a second column 802 are respectively arranged on the front and rear sides of the conventional pallet lifting seat 13. A slide 4 is commonly mounted on both the first column 801 and the second column 802. Multiple sets of connecting rollers 3 are installed on the slide 4, which roll in vertical contact with the first column 801 and the second column 802. This structural design allows the slide 4 to move smoothly up and down on the columns.

[0022] A first winding clamp 101 and a second winding clamp 102 are respectively provided on the front and rear sides of the upper end of the slide block 4. A pivot is provided at the connection point between the first winding clamp 101 and the second winding clamp 102 and the slide block 4, allowing the two winding clamps to rotate around the pivot and perform clamping and releasing operations on the coil 7. A load-bearing plate 1011 is provided on the left and right sides of the top of the first winding clamp 101, and a weighing sensor 1012 is provided under the load-bearing plate 1011 for real-time collection of the weight data of the coil 7.

[0023] The traditional slide lifting seat 13 has multiple sets of sprockets 2 at its top, with chains wrapped around them. The other end of the chains is connected to the slide seat 4. A drag chain 9 is mounted on the chain. The sprockets 2 are connected to the drive motor shaft to provide power for the lifting and lowering of the slide seat 4. Through the cooperation of the sprockets 2 and the chain, the power of the drag chain 9 can be smoothly transmitted to the slide seat 4, achieving precise lifting and lowering control of the slide seat 4.

[0024] Cylinder 601 and cylinder 602 are respectively installed on the front and rear sides of the upper end face of the slide block 4. The push rod shaft ends of cylinder 601 and cylinder 602 are respectively hinged to the outer surfaces of the first coil clamp 101 and the second coil clamp 102. When the push rod of the cylinder moves in extension and retraction, it can control the first coil clamp 101 and the second coil clamp 102 to rotate around the pivot, thereby realizing the clamping and releasing operation of the coil 7, which facilitates the handling and conveying of the coil 7.

[0025] The upper and lower ends of column 1 801 and column 2 802 are respectively provided with upper buffer block 111 and lower buffer block 112. The buffer blocks are made of elastic material, which can effectively offset the impact force generated when the slide 4 ends its lifting and lowering, protect the equipment structure from damage, and also reduce the noise generated when the equipment is running.

[0026] A hydraulic pipe 5 is located in the center of the slide block 4. The hydraulic pipe 5 transmits pressure and power to cylinder 601 and cylinder 602 via hydraulic oil. The hydraulic system features smooth transmission and precise control, which can ensure that the actions of cylinder 601 and cylinder 602 are coordinated and consistent, thereby improving the working efficiency and reliability of the pallet lifting device.

[0027] In some examples, pressure sensors are installed at the ends of the push rods of cylinder 601 and cylinder 602. The pressure sensors monitor the clamping force in real time and automatically trigger an alarm when the clamping force exceeds a set threshold to prevent over-clamping from causing the coil to deform.

[0028] In some examples, the data output of the weighing sensor 1012 is connected to the factory's MES system to automatically bind the coil weight to the production batch information.

[0029] The working principle of this utility model is as follows:

[0030] When using this new pallet lifting device for the HL line conveyor system, firstly, according to the layout requirements of the HL line conveyor system, the traditional pallet lifting seat 13 is fixedly installed in the designated position, ensuring that the first column 801 and the second column 802 are perpendicular to the ground, providing a supporting foundation for the smooth lifting of the slide 4. The slide 4 makes rolling contact with the columns through multiple sets of connecting rollers 3. In its initial state, it is located at the receiving position of the conveyor system, with the first roll clamp 101 and the second roll clamp 102 in a loose state, waiting to receive the coil 7.

[0031] When the coil 7 is conveyed above the pallet lifting device, the control system drives the push rods of cylinder 601 and cylinder 602 to extend. The hinged structure at the end of the push rod shaft pushes the first and second coil clamps 101 to rotate around the pivot until the inner sides of the two clamps are in contact with and clamp the coil 7. At this time, the coil 7 falls onto the load-bearing plate 1011 of the first coil clamp 101. The weight is directly transferred to the weighing sensor 1012 below through the load-bearing plate 1011. The weighing sensor 1012 collects the weight data in real time and transmits it to the control system.

[0032] After weighing is completed, the sprocket 2 at the top of the conventional sliding platform lifting seat 13 rotates under the action of the drive motor, driving the surrounding chain and drag chain 9 to move. The drag chain 9 is connected to the slide 4 through the chain, transmitting power to the slide 4 so that it can vertically rise and fall along the first column 801 and the second column 802. The rolling contact design of the connecting roller 3 reduces the frictional resistance between the slide 4 and the column, ensuring a smooth lifting process. When the slide 4 reaches the target position, the sprocket 2 stops rotating, and the upper buffer block 111 or lower buffer block 112 at the upper and lower ends of the column offsets the inertial impact force of the slide 4, protecting the equipment structure.

[0033] During the lifting and lowering process, the hydraulic pipe 5 in the center of the slide 4 continuously provides pressure to cylinders 601 and 602 via hydraulic oil to ensure that the coil clamp maintains a stable clamping force. When it is necessary to release the coil 7, the control system controls the cylinder push rod to retract, the coil clamp rotates in the opposite direction around the shaft to release, and the coil 7 is received by the subsequent conveying device.

[0034] This device integrates the weighing sensor 1012 into the load-bearing structure of the roll clamp, enabling real-time acquisition of weight data during the roll-on process and avoiding the time loss of secondary handling of the roll to the weighing equipment in the traditional process.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
