Description

Technical Field

[0001] The utility model belongs to the technical field of conveying, and specifically provides an anti-overlapping plate conveying device and a conveying line. Background Art

[0002] During the production process, cleanroom board is filled with glass magnesium board or gypsum board, depending on the core material required by the customer. The commercially available finished glass magnesium board or gypsum board is typically 2400 mm in length. If the customer requires a cleanroom board length of a different length (for example, 3000 mm), the board is lengthened and cut on-site using a conveyor line and cutting equipment before the core material is filled.

[0003] After the glass magnesium board and other panels are transferred to the conveyor line by the robot, the differential speed of the rollers on the conveyor line allows the panels placed later to catch up with the panels placed earlier, so that there is no gap between the panels and they continue to move.

[0004] However, during the transportation process, the plates are prone to warping due to the uneven upper surface of the conveyor line or the plates themselves. In the case of differential speed transportation on the conveyor line, the two plates transported in front and behind are easily overlapped at the end, thereby affecting the normal transportation and cutting of the plates. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-overlapping plate conveying device, which can at least solve one of the above-mentioned technical problems.

[0006] To address the aforementioned issues in the prior art, one or more embodiments of the present invention provide an anti-jamming plate conveying device, comprising a frame, a plurality of rollers, a support frame, and multiple pairs of lifting assemblies. The frame provides support and has a first and a second horizontal and mutually perpendicular orientation. The rollers are arranged sequentially along the first orientation, with their axial directions parallel to the second orientation and their respective ends rotatably connected to the frame. The central axes of the multiple rollers are coplanar.

[0007] A support frame is mounted above the plurality of rollers. A plurality of fluid strips are secured to the support frame's lower surface. The fluid strips extend in a first direction, with the axes of the pulleys on the fluid strips parallel to a second direction. Two lifting assemblies are mounted on either side of the frame along the second direction, and the two lifting assemblies are connected via a belt drive. The lower portions of the lifting assemblies are connected to the frame, and the upper portions of the lifting assemblies are connected to the support frame, enabling the lifting assemblies to drive the support frame to rise and fall relative to the plurality of rollers.

[0008] One or more embodiments of the present invention further provide a conveyor line comprising a plurality of conveyor sections connected end to end in sequence along a first direction, at least one of which is the above-mentioned anti-overlapping plate conveyor.

[0009] Beneficial effects of one or more of the above technical solutions:

[0010] In this solution, a plurality of rollers arranged in sequence along a first direction are provided on the frame, and the rollers are alternately used to realize the driving of conveying the plate in the first direction. In addition, a support frame is provided above the plurality of rollers in this solution, and a plurality of flow strips are fixed to the lower surface of the support frame, and the plurality of flow strips extend along the first direction, and the lifting assembly can smoothly drive the entire support frame and the flow strips to rise and fall vertically to adjust the distance between the flow strips and the conveying surface formed by the plurality of rollers. This arrangement makes it easy to use the flow strips to press down the upward-curved plate, avoiding the overlap of the two plates conveyed in front and behind due to the warping of the ends, thereby avoiding the overlap that affects the conveying and precise cutting of the plate.

[0011] In this solution, the structural arrangement in which the lifting assembly drives the support frame and the flow strip to rise and fall enables the device to adapt to the transportation of plates of different thicknesses, thereby increasing the scope of use of the device.

[0020] Example 1

[0021] like Figure 1-Figure 4 As shown, this embodiment provides an anti-overlapping plate conveying device comprising a frame 1, multiple rollers 12, a support frame 15, and multiple pairs of lifting assemblies. The frame 1 is used for support and has a first direction and a second direction that are horizontal and perpendicular to each other. The rollers 12 are arranged sequentially along the first direction, with their axial directions parallel to the second direction and their ends rotatably connected to the frame 1. The central axes of the multiple rollers 12 are coplanar.

[0022] Specifically, the frame 1 herein comprises a square, horizontal frame formed by mutually perpendicular, horizontally arranged horizontal and vertical frames secured together by welding or bolting. Support legs 7 are provided at each of the four corners of the frame 1, which are used to elevate the frame 1 relative to the ground. Furthermore, the frame 1 is secured to a pair of supports 1201, which are provided at either end of the frame 1 along the second direction. The upper ends of the supports 1201 are configured to pivotally connect to the axial ends of the roller 12. Bearings may also be provided between the supports 1201 to reduce friction during rotation and improve compliance. More specifically, when the supports 1201 are used to mount the roller 12, the supports 1201 support the roller 12 upward. Preferably, the plane in which the central axes of the multiple rollers 12 lie is a horizontal plane. In other configurations, the supports 1201 may have an angle of 0° to 10° with the horizontal plane, meaning that the plane in which the central axes of the rollers 12 lie is an inclined plane.

[0023] In this embodiment, a support frame 15 is positioned above the plurality of rollers 12. A plurality of flow strips 11 are secured to the lower surface of the support frame 15. The flow strips 11 extend in a first direction, with the axial directions of the pulleys on the flow strips 11 parallel to a second direction. Two lifting assemblies are provided in pairs on either side of the frame 1 along the second direction, and the two lifting assemblies are connected via a belt drive. The lower portions of the lifting assemblies are connected to the frame 1, and the upper portions of the lifting assemblies are connected to the support frame 15, enabling the lifting assemblies to drive the support frame 15 up and down relative to the plurality of rollers 12.

[0024] Specifically, the support frame is a square frame, which includes two longitudinal beams 13, which are fixedly connected by multiple cross beams 6. The longitudinal beams 13 are located on both sides of the frame 1 along the second direction. Here, the longitudinal beams 13, the cross beams 6 and the flow strips 11 are fixed by welding or bolting.

[0025] Specifically, the flow strip 11 comprises a long metal profile extending in a first direction, on which a plurality of pulleys are mounted for sequential rotation in the first direction. More specifically, the plane where the central axes of the pulleys lie is parallel to the plane where the central axes of the rollers 12 lie.

[0026] As a specific structural form, in this embodiment, the lifting assembly includes a ball screw mechanism, a mounting bracket 5 is fixed on the frame 1, the screw 9 of the ball screw mechanism is vertically arranged and rotatably connected to the mounting bracket 5, and the nut seat 8 of the ball screw is fixed to the support frame 15.

[0027] In this embodiment, a handwheel 3 is coaxially fixed to the upper end of the screw 9, and a synchronous pulley is coaxially fixed to the upper portion of the screw 9. The pulleys in the two lifting assemblies used in pairs are connected by a synchronous belt. Specifically, the handwheel 3 here is provided with a handle. In the process of turning the handwheel 3, the two screws 9 adapted in pairs are driven by the belt drive assembly to rotate synchronously, thereby causing the support frame 15 to rise and fall at the current position of the ball screw mechanism. By adjusting the different ball screws of this device along the first direction, the height of the entire support frame 15 can be adjusted, and then the distance between the lower surface of the smooth strip 11 and the upper surface of the roller 12 can be adjusted to accommodate the conveying of plates of different thicknesses.

[0028] In some other structural settings, the ball screw assembly can also be replaced with an electric push rod and a hydraulic push rod, etc., which can be set by those skilled in the art.

[0029] In this embodiment, baffles 2 are fixed to both ends of the frame 1 along the second direction. The upper ends of baffles 2 are higher than the upper ends of roller 12, and baffles 2 are perpendicular to the second direction. Specifically, baffles 2 are used to prevent plates on the upper surface of roller 12 from deflecting in the second direction. The height of baffles 2 protruding from the upper surface of roller 12 is greater than the thickness of the plates to be conveyed.

[0030] In this embodiment, the rollers 12 are rubber-coated rollers, and multiple rollers 12 are connected by a belt drive mechanism for synchronous rotation. Specifically, one of the rollers 12 is connected to the motor 4 via a belt drive mechanism or a gear drive mechanism, thereby transmitting rotational power to the rollers 12. Adjacent rollers 12 are connected by belt drive assemblies or gear drive assemblies, so that all rollers 12 are powered.

[0031] Example 2

[0032] This embodiment also provides an anti-overlapping plate conveying device, which has basically the same structural arrangement as that of embodiment 1, except that this embodiment further includes a laser probe for detecting whether there is any overlapping of plates on the upper surface of the roller 12 of the plate conveying device.

[0033] In this embodiment, a pneumatic gripper is further included. The pneumatic gripper is supported by the frame 1 and can be raised and lowered vertically to press or move away from the plate being transported on the upper surface of the roller 12 .

[0034] When the panels are overlapped, the laser probe transmits a signal to the controller, which controls the pneumatic gripper to descend and press the panel behind, while the panel ahead continues to be transported forward, so that the front and rear panels are free from overlap.

[0035] Example 3

[0036] This embodiment also provides a conveyor line, comprising a plurality of conveyor sections connected end to end in sequence along a first direction, at least one of which is an anti-overlapping plate conveyor in the above-mentioned embodiment 1 or embodiment 2.

[0037] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments described above. However, it is easy for those skilled in the art to understand that the scope of protection of the present application is not limited to the above preferred embodiments. Without departing from the technical principles of the present application, those skilled in the art may split and combine the technical solutions in the above preferred embodiments, and may also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the scope of protection of the present application.
