Description

Technical Field

[0001] This utility model relates to the field of corner conveyor technology, and in particular to a smooth transition device for conveyor lines. Background Technology

[0002] A conveyor line is a device used for the continuous transport of materials or products, primarily for achieving efficient and automated material handling and transmission in industrial production processes. In the door and window manufacturing industry, to achieve automatic corner assembly of doors and windows, fully automatic CNC four-head corner assembly machines have been developed based on existing technology, such as... Figure 8 As shown, to meet the needs of automatic feeding, a feeding section conveyor line and a corner assembly section conveyor line are usually designed. The corner assembly section conveyor line is directly designed on the four-head corner assembly machine. Both sections of the conveyor line usually use conveyor belts (synchronous belts) for transportation. Because the two sections of the conveyor belt are supported by pulleys and are in an arc shape, there is a large gap between two adjacent conveyor belts. This gap can have an adverse effect on the conveyed material, such as vibration, jamming, and unstable transportation. In the field of corner assembly technology, the material on the conveyor line is a frame of material with corner brackets already threaded on (not yet assembled, just spliced ​​together, and not secure). When the frame passes through the gap, it will be blocked (i.e., jammed, causing vibration), which can easily cause the assembled frame to separate, thus seriously affecting the quality of subsequent corner assembly.

[0003] Currently, the main methods for solving the gap problem in conveyor lines are as follows: First, staggering the two conveyor sections. This solution works in other technical fields, but in the field of corner assembly, the corner assembly section needs to move and adjust with the corner assembly machine head to meet the corner assembly requirements of different door and window sizes, thus easily causing interference problems. Second, designing a separate transition roller or transition plate between the two conveyor sections (e.g., a conveyor belt transition bridge disclosed in Chinese patent, authorization announcement number: CN201980750U). While this structure solves the adverse effects of gaps to some extent, in the corner assembly field, material frames that have not yet been cornered will still be adversely affected. The main reason is that the conveyor belt has a transmission speed, while the transition roller or transition plate does not. Therefore, in addition to some vibration, the material frame will also be affected by the speed inconsistency. These shortcomings may have little impact on other materials, but they will have serious adverse effects on material frames that have not yet been cornered and reinforced. Utility Model Content

[0004] This invention provides a smooth transition device for conveyor lines, solving the problems existing in the prior art. It has advantages such as reasonable structural design, no interference, good synchronization, and smooth transition.

[0005] One of the technical solutions adopted by this utility model is: A smooth transition device for a conveyor line includes a transition main shaft, which is connected to and rotates synchronously with a conveyor belt pulley shaft rotatably mounted on the conveyor line, or the transition main shaft and the conveyor belt pulley shaft are integrally formed. A conveyor belt pulley is mounted on the conveyor belt pulley shaft, and a synchronous conveyor belt is provided between the two pulleys. A main transition pulley is mounted on the main transition shaft, and a transition support is rotatably mounted on the main transition shaft. A secondary transition shaft is fixed at the other end of the secondary transition support, and a secondary transition pulley is rotatably mounted on the secondary transition shaft. A synchronous transition belt is provided between the main transition pulley and the secondary transition pulley. A rotary drive mechanism for driving the transition support to rotate is provided on the conveyor line. When the transition support is horizontally positioned, the upper end of the synchronous transition belt is aligned with the upper end of the synchronous conveyor belt.

[0006] The transition main shaft is connected to the conveyor pulley shaft via a coupling.

[0007] The main transition pulley is mounted on the main transition shaft via a key connection; the auxiliary transition pulley is rotatably mounted on the auxiliary transition shaft via bearing A.

[0008] The transition support includes two transition support plates spaced apart, with a support shaft connecting the two transition support plates. The transition main pulley is located between the two transition support plates, and the transition support plates are rotatably mounted on the transition main shaft via bearing B.

[0009] The rotary drive mechanism includes a mounting plate, on which a cylinder seat is provided. A drive cylinder is rotatably mounted on the cylinder seat, and the drive cylinder is rotatably connected to a support shaft located below via a spherical bearing.

[0010] The conveyor line includes a conveyor support frame, with conveyor pulley shafts rotatably mounted at both ends of the conveyor support frame. Conveyor pulleys are mounted on the conveyor pulley shafts, and a conveyor timing belt is provided between the two conveyor pulleys. One of the conveyor pulley shafts is connected to a conveyor reducer, which is mounted on the conveyor support frame and connected to a conveyor motor.

[0011] The beneficial effects of this utility model are: By designing a transition main shaft that connects to or is integrally formed with the conveyor belt pulley shaft, synchronous rotation of the transition synchronous belt and the conveyor synchronous belt is achieved. This effectively eliminates the adverse effects of the arc gap between the two conveyor sections, ensuring a smooth transition. The design of a rotatable transition support and a rotary drive mechanism allows the smooth transition device to be stored and concealed via rotary drive, without affecting the normal movement and adjustment of the corner section conveyor line.

[0013] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0015] like Figure 1-6As shown, the smooth transition device for the conveyor line includes a transition main shaft 1. The transition main shaft 1 is connected to and rotates synchronously with a conveyor belt pulley shaft 202 rotatably mounted on the conveyor line 2, or the transition main shaft 1 and the conveyor belt pulley shaft 202 are integrally formed. A conveyor belt pulley 203 is provided on the conveyor belt pulley shaft 202, and a conveyor timing belt 204 is provided between the two conveyor belt pulleys 203. A transition main pulley 3 is mounted on the transition main shaft 1, and a transition support 4 is rotatably mounted on the transition main shaft 1. A transition auxiliary shaft 5 is fixedly mounted on the other end of the transition support 4, and a transition auxiliary pulley 6 is rotatably mounted on the transition auxiliary shaft 5. A transition timing belt 7 is provided between the transition main pulley 3 and the transition auxiliary pulley 6. A rotary drive mechanism 8 is provided on the conveyor line 2 to drive the transition support 4 to rotate. When the transition support 4 is horizontally mounted, the upper end of the transition timing belt 7 is aligned with the upper end of the conveyor timing belt 204. By designing the transition main shaft 1 to be connected to or integrally formed with the conveyor belt pulley shaft 202, the synchronous rotation and conveying of the transition synchronous belt 7 and the conveyor synchronous belt 204 are achieved, which can effectively eliminate the adverse effects caused by the arc gap between the two conveyor lines and achieve a smooth transition. By designing a rotatable transition support 4 and a rotary drive mechanism 8, the smooth transition device can be stored and hidden by rotary drive without affecting the normal movement and adjustment of the corner section conveyor line.

[0016] The transition main shaft 1 is connected to the conveyor pulley shaft 202 via a coupling. This is a common connection method for two shafts, and different couplings can be selected according to requirements in practical applications. Its main purpose is to achieve synchronous rotation between the transition main shaft 1 and the conveyor pulley shaft 202.

[0017] The transition main pulley 3 is mounted on the transition main shaft 1 via a key connection 9; the transition auxiliary pulley 6 is rotatably mounted on the transition auxiliary shaft 5 via a bearing A10. The key connection 9 enables the transition main pulley 3 to rotate synchronously with the transition main shaft 1, and the bearing A10 enables the transition auxiliary pulley 6 to be rotatably connected to the transition auxiliary shaft 5.

[0018] The transition support 4 includes two spaced-apart transition support plates 401, with a support shaft 402 connecting the two transition support plates 401. The transition main pulley 3 is located between the two transition support plates 401, and the transition support plates 401 are rotatably mounted on the transition main shaft 1 via bearing B11. The specific structure of the transition support 4 is given, which has the advantages of simple and reasonable structure and easy installation of various components.

[0019] The rotary drive mechanism 8 includes a mounting plate 801, on which a cylinder seat 802 is provided. A drive cylinder 803 is rotatably mounted on the cylinder seat 802. The drive cylinder 803 is rotatably connected to the support shaft 402 located below via a spherical bearing 804. The transition support 4 is rotated pneumatically, thereby achieving both its erection (the transition support is horizontal, providing a smooth transition) and its concealment (the transition support is vertical, avoiding interference and facilitating the movement and adjustment of the corner section conveyor line).

[0020] The conveyor line 2 includes a conveyor support 201, with conveyor pulley shafts 202 rotatably mounted at both ends. Conveyor pulleys 203 are mounted on the conveyor pulley shafts 202, and a synchronous conveyor belt 204 is provided between the two conveyor pulleys 203. One of the conveyor pulley shafts 202 is connected to a conveyor reducer 205, which is mounted on the conveyor support 201 and connected to a conveyor motor 206. The specific structure of the conveyor line 2 is given, enabling material conveying.

[0021] Instructions for use of the smooth transition device for the conveyor line in this application: The following explanation uses a CNC four-head corner assembly machine as an example.

[0022] like Figure 7 As shown, the CNC four-head corner assembly machine 12 is equipped with two corner assembly section conveyor lines 13. A smooth transition device as described in this application is installed at the inlet end (i.e., the feeding end) of the corner assembly section conveyor line 13 (a smooth transition device is usually not required at the outlet end because the material frame 16 is already firmly secured after corner assembly, so the arc gap has virtually no impact on it). The transition spindle 1 and the conveyor belt pulley shaft 202 are integrally formed. In the initial state, the drive cylinder 803 will lower the transition support 4 (i.e., vertically hidden, as shown). Figure 6 (As shown).

[0023] First, adjust the spacing between the two sets of corner assembly heads 14 according to the size of the material frame 16 (the corresponding two corner assembly section conveyor lines 13 will also move along with it). After adjustment, drive cylinder 803 drives the transition support 4 to rise (i.e., set horizontally to ensure a smooth transition). Place the assembled material frame 16 on the feeding section conveyor line 15, and then the feeding section conveyor line 15 will convey the material frame 16 forward and smoothly enter the corner assembly section conveyor line 13 via the transition synchronous belt 7. Then, perform the corresponding subsequent corner assembly processing. After the corner assembly processing is completed, the material frame 16 can be conveyed out.

[0024] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0025] Any aspects of this utility model not described in detail are known to those skilled in the art.
