Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a conveying device. Background Technology

[0002] In iron material cutting production lines, it is common to encounter situations where the material to be cut needs to be transferred from one workstation to another. However, due to the dense layout of the equipment in the production line, there may be insufficient space under the material movement path, resulting in no extra space to install the equipment.

[0003] To address these issues, the industry typically employs robotic arms, which pick up and precisely place the materials to be cut, thus enabling material transfer. However, due to limitations in their structure and function, robotic arms can only operate reciprocally and cannot continuously transfer materials. Utility Model Content

[0004] In view of this, the present invention aims to provide a conveying device for continuously conveying cut materials.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A conveying device includes a gantry frame, a conveyor belt, and a magnetic suction assembly;

[0007] The conveyor belt is disposed on the upper part of the gantry frame, and the conveyor belt has a horizontally arranged working surface facing downward;

[0008] The magnetic suction assembly is disposed on the inner side of the working belt surface;

[0009] Along the conveying direction of the conveyor belt, the working belt surface includes a front section and a rear section. The magnetic attraction component acts on the front section to attract ferromagnetic material to adhere to the working belt surface, and the rear section serves as a guide for the movement of the ferromagnetic material.

[0010] Furthermore, the portal frame includes two uprights, a crossbeam, and a lifting assembly;

[0011] The crossbeam is vertically adjustable between the two uprights and is equipped with the conveyor belt and the magnetic suction assembly.

[0012] The lifting assembly is mounted on the upright and is used to drive the horizontal frame to lift.

[0013] Furthermore, the upright frame is provided with a vertical guide rod, and the horizontal frame is vertically slidably connected to the guide rod.

[0014] Furthermore, the lifting assembly includes a screw and a connector;

[0015] The screw is vertically rotatably connected to the upright frame;

[0016] The connector is threadedly connected to the screw and fixedly connected to the cross frame;

[0017] When the screw rotates, the connector provides a lifting and lowering drive for the crossbeam.

[0018] Furthermore, one set of the lifting assembly is provided on each of the two uprights;

[0019] A linkage component is provided between the screws of the two sets of lifting assemblies to enable the two screws to rotate at the same speed.

[0020] Furthermore, the linkage component includes:

[0021] Two bevel gears are coaxially and fixedly connected to the two screws, respectively;

[0022] The gear shaft is rotatably mounted on the upright and meshes with the two bevel gears respectively.

[0023] Furthermore, it includes a drive unit capable of driving any of the screws to rotate.

[0024] Furthermore, the portal frame is provided with a vertical through mounting hole, and the portal frame has a support member at the lower end of the mounting hole and a crimping member at the upper end of the mounting hole;

[0025] The magnetic suction assembly is disposed in the mounting hole and is pressed onto the support by the crimping member.

[0026] Furthermore, the crimping member bolts together the portal frame and the magnetic suction assembly.

[0027] Compared with the prior art, this utility model has the following advantages:

[0028] The conveying device described in this utility model can attract ferromagnetic materials upwards through a magnetic attraction component. The materials adhere to the working belt surface and are moved forward by the working belt surface in the conveying direction without occupying the space below the material conveying path. The conveyor belt can work in a cycle, and the magnetic attraction component can also work continuously, enabling continuous material transfer. For longer materials, the front section of the working belt attracts the materials, while the rear section guides them. When the materials are attracted and put down, they are less likely to bump into the front and rear work positions, and the materials are less likely to be damaged.

[0029] The system is equipped with a liftable crossbeam and driven by a lifting assembly, which can raise the conveyor belt and magnetic suction assembly to different heights to change the distance between the front and rear workstations, thereby adapting to materials of different heights and weights and increasing the applicability of the conveying device.

[0030] The guide rod can guide the lifting and lowering of the crossbeam, making the crossbeam more stable during lifting and lowering and less likely to deviate from the lifting and lowering position.

[0031] The connecting piece, which secures the crossbeam, acts as an anti-rotation component. As the screw rotates, the connecting piece moves up and down, thus moving the crossbeam.

[0032] The two sets of lifting components can evenly lift the crossbeam from both sides. Through the action of the linkage component, the screws of the two sets of lifting components can rotate at the same speed, realizing the synchronous lifting and lowering of the crossbeam.

[0033] The linkage component adopts bevel gear transmission, which provides stable transmission and strong load-bearing capacity. Even when subjected to large loads, it can effectively transmit power and ensure the normal operation of the two sets of lifting components.

[0034] By setting up a drive unit to drive one screw, the other screw can rotate accordingly. The lifting and lowering of the crossbeam can be achieved by setting up only one drive unit.

[0035] Placing the magnetic suction component inside the mounting hole makes the conveying device structure more compact. The designer's support component supports the magnetic suction component with less obstruction, which helps to enhance the attraction of materials. The crimping component can keep the magnetic suction component more firmly in the mounting hole.

[0036] The crimping parts are bolted to the gantry frame and the magnetic assemblies, which facilitates the installation of the magnetic assemblies and makes them more securely fixed. Attached Figure Description

[0053] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] This embodiment relates to a conveying device for continuously conveying cut materials.

[0055] In terms of overall structure, refer to Figures 1 to 3 As shown, a conveying device in this embodiment includes a gantry frame 1, a conveyor belt 2, and a magnetic suction assembly 3.

[0056] The conveyor belt 2 is disposed on the upper part of the gantry frame 1, and the conveyor belt 2 has a horizontally arranged working belt surface 201 facing downwards. The magnetic attraction assembly 3 is disposed on the inner side of the working belt surface 201. Along the conveying direction of the conveyor belt 2, the working belt surface 201 includes a front section 201a and a rear section 201b. The magnetic attraction assembly 3 acts on the front section 201a to attract ferromagnetic materials to adhere to the working belt surface 201, and the rear section 201b serves as a guide for the movement of the ferromagnetic materials.

[0057] As configured above, the conveying device in this embodiment can attract ferromagnetic materials upwards through the magnetic suction component 3. The materials adhere to the working belt surface 201 and are moved forward in the conveying direction by the working belt surface 201 without occupying the space below the material conveying path. The conveyor belt 2 can work in cycles, and the magnetic suction component 3 can also work continuously, enabling continuous material transfer. For longer materials, the front section 201a of the working belt surface 201 adsorbs the materials, and the rear section 201b guides the materials. When the materials are picked up and put down, they are less likely to bump into the front and rear work positions, and the materials are less likely to be damaged.

[0058] Based on the above overview, specifically, the conveying device in this embodiment can span across a long line to transport ferromagnetic materials such as iron plates and iron profiles that can be attracted by magnets. Conventional conveying devices often experience material bumps and collisions when transporting materials from one workstation to another, but this embodiment uses magnetic attraction for material handling, effectively reducing these collisions. The conveyor belt 2 includes a belt surface and multiple belt rollers, with the belt surface driven by an active belt roller to achieve cyclic movement. The magnetic attraction component 3 in this embodiment is an electromagnet, which has the advantage of controllable magnetic force.

[0059] Regarding the specific structure of the gantry frame 1, it includes two uprights 101, a crossbeam, and a lifting assembly 103. The crossbeam 102 is vertically oriented between the two uprights 101 and is equipped with a conveyor belt 2 and a magnetic suction assembly 3. The lifting assembly 103 is mounted on the uprights 101 and is used to drive the crossbeam 102 to rise and fall. By using a vertically oriented crossbeam 102 and driving it with the lifting assembly 103, the conveyor belt 2 and the magnetic suction assembly 3 can be raised to different heights to change the distance from the preceding and following workstations, thus adapting to materials of different heights and weights and increasing the applicability of the conveying device.

[0060] Specifically, the lifting assembly 103 includes a screw 1031 and a connector 1032. The screw 1031 is vertically rotatably connected to the upright frame 101. The connector 1032 is threadedly connected to the screw 1031 and fixedly connected to the cross frame 102. When the screw 1031 rotates, the connector 1032 drives the lifting of the cross frame 102. The connector 1032's fixed connection to the cross frame 102 serves as an anti-rotation mechanism. When the screw 1031 rotates, the connector 1032 can move and lift accordingly, thus moving the cross frame 102. In this embodiment, the connector 1032 is a nut with two radially extending symmetrical connecting ears. The connecting ears have through holes, and bolts are used to thread the connector 1032 onto the cross frame 102 through the through holes. Of course, the lifting assembly 103 can also adopt other structures such as electric push rods or hydraulic cylinders, as long as the crossbar 102 is installed on the lifting end of the lifting assembly 103.

[0061] Preferably, to improve the stability of lifting the crossbeam 102, one set of lifting components 103 is provided on each of the two uprights 101. A linkage component 4 is provided between the screws 1031 of the two sets of lifting components 103 to ensure that the two screws 1031 rotate at the same speed. By setting two sets of lifting components 103, the crossbeam 102 can be lifted evenly from both sides. Through the action of the linkage component 4, the screws 1031 of the two sets of lifting components 103 can rotate at the same speed, realizing the synchronous lifting of the crossbeam 102.

[0062] Secondly, the linkage assembly 4 includes two bevel gears 401 and a gear shaft 402, which are coaxially fixed to two screws 1031 respectively. The gear shaft 402 is rotatably mounted on the upright frame 101 and meshes with the two bevel gears 401 respectively. The linkage assembly 4 uses bevel gear 401 transmission, which provides stable transmission and strong load-bearing capacity. Even under large loads, it can effectively transmit power and ensure the normal operation of the two sets of lifting assemblies 103. Specifically, in this embodiment, the two screws 1031 rotate in opposite directions and their threads turn in opposite directions. This arrangement allows the connecting parts 1032 on the two screws 1031 to rise and fall synchronously, driving the crossbeam 102 to move.

[0063] Furthermore, to facilitate the lifting and lowering of the crossbeam 102, the conveying device includes a drive unit 5, which can drive any of the screws 1031 to rotate. By setting the drive unit 5 to drive one screw 1031, the other screw 1031 can rotate accordingly; thus, lifting and lowering of the crossbeam 102 can be achieved with only one drive unit 5. In this embodiment, the drive unit 5 is a combination of a servo motor, a reducer, and a synchronous belt drive assembly. The servo motor drives the synchronous pulley to rotate via the reducer, and the synchronous pulley drives another synchronous pulley mounted on the screw 1031 to rotate via the synchronous belt, thereby driving the screw 1031. It is understood that the drive unit 5 can also be a servo motor that directly drives the screw 1031, as long as it can drive the screw 1031 to rotate.

[0064] As an aid to the lifting and lowering movement of the crossbeam 102, the upright frame 101 is provided with a vertical guide rod 104, and the crossbeam 102 is vertically slidably connected to the guide rod 104. The guide rod 104 can guide the lifting and lowering of the crossbeam 102, making the crossbeam 102 more stable during lifting and lowering and less likely to deviate from the lifting position. The upper part of the upright frame 101 is provided with a rectangular frame, and the end lifting mechanism of the crossbeam 102 is set within the frame. In this embodiment, each lifting assembly 103 is equipped with two guide rods 104, which are circular cross-section guide rods 104, and are set within the frame. The two guide rods 104 of each set are respectively set on both sides of the screw 1031.

[0065] In addition, to optimize the structural layout of the gantry frame 1, a vertically penetrating mounting hole 1021 is provided on the gantry frame 1. The lower end of the mounting hole 1021 has a support member 105, and the upper end has a pressing member 106. The magnetic suction assembly 3 is disposed in the mounting hole 1021 and is pressed against the support member 105 by the pressing member 106. Disposing of the magnetic suction assembly 3 in the mounting hole 1021 makes the conveying device structure more compact. The support member 105 provides support for the magnetic suction assembly 3 with less obstruction, which is beneficial for enhancing the attraction of materials. The pressing member 106 ensures that the magnetic suction assembly 3 is more securely held in the mounting hole 1021.

[0066] In this embodiment, the mounting hole 1021 is rectangular, and the magnetic component 3 is also rectangular, matching the shape of the mounting hole 1021. Four support members 105 are welded to the bottom of the crossbeam 102, each supporting one corner of the magnetic component 3, leaving space for the magnetic component 3 to better interact with materials. The pressing member 106 is raised by the pad 107, allowing it to press against the magnetic component 3, which protrudes above the opening of the mounting hole 1021.

[0067] Furthermore, the crimping member 106 is bolted to the portal frame 1 and the magnetic absorbing assembly 3. The bolted connection of the crimping member 106 to the portal frame 1 and the magnetic absorbing assembly 3 facilitates the installation of the magnetic absorbing assembly 3 and also makes the fixation of the magnetic absorbing assembly 3 more secure. In this embodiment, the crimping member 106 and the pad 107 have corresponding through holes, allowing bolts to pass through the crimping member 106 and the pad 107 to screw onto the crossbeam 102, thereby achieving the crimping of the magnetic absorbing assembly 3. Four sets of crimping members 106 and pads 107 are provided, respectively arranged on the crossbeam 102, corresponding to both sides of the width direction of the magnetic absorbing assembly 3.

[0068] In this embodiment, the conveying device uses the magnetic suction component 3 to attract ferromagnetic materials upwards. The materials adhere to the working belt surface 201 and are moved forward in the conveying direction by the working belt surface 201, without occupying the space below the material conveying path. The conveyor belt 2 can operate cyclically, and the magnetic suction component 3 can also operate continuously, enabling continuous material transfer.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
