Description

Technical Field

[0001] The utility model belongs to the technical field of parts conveying devices, and in particular relates to a conveying device for special-shaped parts. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both bulk materials and piece items.

[0004] When using a belt conveyor to transport automotive stampings, there are many V-shaped parts in automotive stampings. The shape and discharge posture of these parts are V-shaped. When using a traditional flat belt for transmission, the support point of the parts is the narrow and long part inside the parts. During the transmission process, the parts are prone to swaying, resulting in the problem of inability to accurately position. In addition, some parts have weak points on the bearing surface. The shape and discharge posture of these parts result in multiple support points on the lower bearing surface, some of which are relatively weak. When using a traditional flat belt for transmission, these weak support points cannot be avoided, resulting in poor support and unstable posture of the parts, resulting in the problem of inability to accurately position.

[0005] At the same time, the currently used flat wide belt conveyor, the parts fall onto the wide belt as a whole, and if there are V-shaped parts, shaking problems will occur. If the support points under some parts are relatively weak, they cannot be avoided, and there is a tendency for slippage between the belt and the pulley, and between the parts and the belt during the conveying process. In addition, narrow belts can only meet the needs of some special-shaped parts. Since the belt spacing cannot be adjusted, it cannot meet the needs of more different special-shaped parts for stable posture and non-slip transportation. Utility Model Content

[0006] The purpose of the utility model is to provide a conveying device for special-shaped parts, which improves the position accuracy and stability of special-shaped parts during the conveying process by adjusting the distance between the conveying mechanisms and the height of the conveying mechanisms through the provision of a lateral movement adjustment structure and a lift, and can meet the transportation needs of special-shaped parts.

[0007] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0008] In the first aspect, an embodiment of the utility model provides a conveying device for special-shaped parts, including at least two conveying mechanisms, each of which is installed on a lateral movement adjustment structure, and the conveying mechanism includes a beam, and a conveying power structure is provided on the beam, and the distance between the two conveying mechanisms is adjusted by the lateral movement adjustment structure.

[0009] As a further technical solution, the lateral movement adjustment structure includes a lateral movement bracket, on which a motor, a lead screw and a nut are installed. The lateral movement bracket is connected to the beam. The motor drives the lead screw to rotate, and the lateral movement bracket and the beam are driven to move through the cooperation of the lead screw and the nut.

[0010] As a further technical solution, at least two lateral movement adjustment structures are provided, and the lead screw and the nut of each lateral movement adjustment structure are respectively installed on two adjacent lateral movement brackets.

[0011] As a further technical solution, guide rails are installed on two adjacent transverse moving brackets, and a plurality of guide rails are provided so that the transverse moving bracket can move linearly along the guide rails.

[0012] As a further technical solution, the beam is installed on the transverse support of the transverse movement adjustment structure through a lift, and the lift adjusts the height of the conveying mechanism.

[0013] As a further technical solution, the conveying mechanism includes a belt conveying mechanism or a chain conveying mechanism.

[0014] As a further technical solution, when the conveying mechanism adopts a belt conveying mechanism, a belt is arranged on the beam, and the conveying power structure of the belt conveying mechanism includes a driving motor and a driving wheel, and the driving motor drives the belt to move through the driving wheel.

[0015] As a further technical solution, it also includes a pulley, on which a belt is installed, a belt guide strip is arranged on the surface where the belt contacts the pulley, and grooves matching the belt guide strip are arranged on the surface of the pulley; baffles are also arranged on both sides of the pulley.

[0016] As a further technical solution, the belt is a synchronous toothed belt, and an anti-slip pattern is provided on the surface of the belt that contacts the special-shaped part.

[0017] As a further technical solution, detection switches and anti-deviation guide wheels are also provided on both sides of the belt, and the detection switch is a photoelectric detection switch.

Suitable support points can be selected according to the shape characteristics of each part. The spacing of the belts can be adjusted to adapt to the effective support points of each part while avoiding weak protruding points in the shape, so as to reduce the problem of shaking and swaying caused by unstable support during transmission.

[0021] The belt of the utility model adopts a synchronous toothed belt made of a cut-resistant and wear-resistant composite material.

DETAILED DESCRIPTION

[0034] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Example 1

[0036] In a typical implementation of the present invention, Figure 1 and Figure 2 As shown, a conveying device for special-shaped parts is provided, including at least two conveying mechanisms, each of which is installed on a lateral movement adjustment structure. The conveying mechanism includes a beam, and a conveying power structure is arranged on the beam. The distance between the two conveying mechanisms is adjusted by the lateral movement adjustment structure.

[0037] In this embodiment, all belt conveyor mechanisms are arranged on a base 5, which provides support for other structures of the device. The overall structure of the base is a frame structure welded together with profiles (such as rectangular tubes), on which installation surfaces for other structures are left. The gaps on the upper surface of the profile are paved with patterned plates, and adjustable foot cups are provided under the base as support.

[0038] like Figure 3 and Figure 4 As shown, the lateral movement adjustment structure includes a lateral movement bracket 2, a motor and a synchronous belt pair 6 and a lead screw 3. The lateral movement bracket 2 is connected to the beam 1. The motor 601 drives the lead screw 3 to rotate through the synchronous belt pair 602, thereby driving the lateral movement bracket 2 and the beam 1 to move. In this embodiment, the motor and the synchronous belt pair 6 and the lead screw 3 are installed on the lateral movement bracket. A nut 9 is set at one end of the lead screw. The lead screw drives the lateral movement bracket 2 and the beam 1 to move through the cooperation of the lead screw and the nut, so that the two adjacent conveying mechanisms are brought closer. The lateral movement adjustment structure can be set in multiples as needed, and two adjacent lateral movement adjustment structures are relatively arranged, such as Figure 3 As shown, the lead screw of one of the lateral moving structures is arranged on the lower lateral moving bracket, and the nut is arranged on the upper lateral moving bracket, while the lead screw of the adjacent lateral moving structure is arranged on the upper lateral moving bracket, and the nut is arranged on the lower lateral moving bracket, and the lead screw corresponds to the nut.

[0039] Furthermore, a guide rail 4 is installed on two adjacent transverse moving brackets 2, the motor and the lead screw provide power for the transverse movement, and the linear guide rail provides guidance for the transverse movement, so that the transverse moving bracket 2 moves in a straight line along the guide rail 4, realizing the transverse movement of the transverse moving bracket and the beam and then realizing the movement of the entire belt conveyor mechanism, so as to adjust the distance between the two adjacent belt conveyor mechanisms as needed to meet the conveying requirements of different special-shaped parts.

[0040] In this embodiment, it is considered that the special-shaped parts may require multiple conveying mechanisms of different heights for support, such as Figure 5 As shown, the beam 1 is installed on the transverse support 2 of the transverse movement adjustment structure through the elevator 201, and the height of the conveying mechanism is adjusted by the elevator to meet the different height requirements of special-shaped parts during the conveying process.

[0041] The conveying mechanism mentioned in this embodiment can be a belt conveying mechanism, a chain conveying mechanism or any other existing conveying mechanism.

[0042] This embodiment takes the belt conveyor mechanism as an example. Figure 2 As shown, when the conveying mechanism adopts a belt conveying mechanism, a belt 10 is arranged on the beam, and the conveying power structure of the belt conveying mechanism includes a driving motor 701 and a driving wheel 702. The belt 10 is installed on the driving wheel 702. The driving wheel 702 rotates under the drive of the driving motor, thereby driving the belt to move.

[0043] Furthermore, if Figure 6 and Figure 7As shown, the belt conveying power structure also includes a pulley 11, and a plurality of pulleys 11 are provided. The pulleys are respectively installed at the two ends and the middle position of the beam as driven wheels, and play a role in reversing and guiding the belt. The belt 10 is installed on the pulley 11, and a belt guide strip 1001 is provided on the surface of the belt 10 in contact with the pulley 11. The surface of the pulley is provided with a groove matching the belt guide strip 1001. Through the cooperation of the guide strip 1001 and the groove, it can be ensured that the belt does not deviate during the process of conveying parts. The two ends of the pulley 11 are installed on the beam through bearings 12, and the beams at both ends of the pulley are connected through the beam auxiliary connecting rod 13.

[0044] Furthermore, baffles 17 are provided on both sides of the pulley 11. The baffles 17 ensure that the belt always moves in the groove between the baffles on both sides when passing through the pulley, thereby preventing the belt from deviating.

[0045] To further prevent the belt from running off track, Figure 2 and Figure 8 As shown, both sides of the belt are further provided with anti-deviation guide wheels 15 and detection switches 16. The anti-deviation guide wheels 15 are installed on the beam through the beam auxiliary welding block 14. The anti-deviation guide wheels 15 play a limiting role in the movement of the belt. The detection switch adopts a photoelectric detection switch. The detection switch is provided with a U-shaped opening. The U-shaped opening faces the belt. One end of the U-shaped opening is a transmitting end and the other end is a receiving end. They are respectively placed on both sides of the belt thickness direction, so as to detect whether the belt deviates into the U-shaped opening of the detection switch. When the belt deviates into the U-shaped opening, the belt will run into the U-shaped opening of the detection switch, and the photoelectric data will be blocked at one time, so that the photoelectric switch detects the blocked data, and then determines that the belt deviates to this side. The detection switch is connected to the alarm device. When the belt deviates, the alarm device sounds an alarm to remind the staff to detect and repair.

[0046] In this embodiment, if Figure 6 As shown, the belt 10 adopts a synchronous toothed belt, that is, a T-shaped tooth is arranged on the surface where the belt contacts the pulley, and the T-shaped tooth is arranged parallel to the axis of the pulley. The T-shaped tooth cooperates with the servo motor and the driving wheel to realize the precise positioning of the synchronous belt in the conveying direction. At the same time, the belt is supported by a composite material that is resistant to cutting and wear, so that it can meet the conveying of relatively sharp automotive special-shaped parts. The surface where the belt contacts the special-shaped parts is provided with an anti-slip pattern, such as an anti-slip pattern similar to a golf pattern formed by a rolling process, which increases the friction between the conveyor belt and the stamping parts, thereby reducing the relative sliding displacement between the conveyor belt and the stamping parts.

[0047] To solve the problem of swaying and shaking that V-shaped parts are prone to during flat belt transmission, the utility model adopts multi-belt support. Suitable support points can be selected according to the shape characteristics of each part. The spacing of the belts can be adjusted to adapt to the effective support points of each part while avoiding weak protruding points in the shape, so as to reduce the swaying and shaking problems caused by unstable support during transmission.

[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
