Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, specifically to a conveying limit device for automated production lines. Background Technology

[0002] In modern intelligent manufacturing processes, automated production lines often use roller conveyors to achieve continuous workpiece transport. To meet the precise positioning requirements of workpieces of different specifications, limit devices are usually installed on the conveyor line.

[0003] The existing fixed-installation limit devices have shortcomings. When it is necessary to temporarily adjust the production line layout, the limit devices must be completely disassembled to avoid interfering with the operation of other equipment. This process requires special tools and is time-consuming, resulting in reduced equipment conversion efficiency. This problem is particularly prominent in production lines that require frequent switching of production modes. Utility Model Content

[0004] The purpose of this invention is to provide a conveying limit device for automated production lines to solve the problems mentioned in the background art.

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

[0007] The frame has vertical guide slots on both sides, and a pressure plate is movably installed between the two guide slots. A lifting mechanism is provided between the pressure plate and the top of the frame.

[0008] The pressure rods are symmetrically and vertically fixed to the bottom ends of both sides of the pressure plate, and the bottom ends of the pressure rods are provided with limit mechanisms.

[0009] The roller conveyor is located below the frame, and there is a rotation positioning mechanism between the frame and the roller conveyor.

[0010] Preferably, the lifting mechanism includes a lead screw threaded to the middle of the top of the frame and a handwheel fixedly installed at the top of the lead screw. The bottom end of the lead screw is rotatably connected to the middle of the pressure plate through a bearing, and the two ends of the pressure plate are slidably connected to the guide groove.

[0011] Preferably, the limiting mechanism includes a connector that is horizontally fixed to the bottom end of the pressure rod, and a vertical limiting frame is fixedly connected to the bottom end of each of the two connectors on opposite sides. Several guide rollers are rotatably connected to each of the two limiting frames on opposite sides through bearings.

[0012] Preferably, the rotary positioning mechanism includes a rotary mechanism and a positioning mechanism. The rotary mechanism includes a rotary adjustment shaft rotatably connected to the bottom ends of both sides of the frame via bearings. One end of the rotary adjustment shaft is rotatably connected to the body of the roller conveyor via bearings.

[0013] Preferably, the positioning mechanism includes positioning holes opened at the upper and lower ends of the roller conveyor near the rotary adjustment shaft, and locking screws are threadedly connected to both sides of the frame near the upper end of the rotary adjustment shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This automated production line conveyor limiting device, through the combined use of a lifting mechanism and a rotary positioning mechanism, enables the frame to be quickly folded and stored and unfolded and reset. It solves the technical problem in the prior art that the limiting device must be completely disassembled in order to adjust the production line layout, significantly improving the equipment conversion efficiency. It is particularly suitable for production lines that need to frequently switch production modes.

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] A conveyor limiting device for an automated production line includes a frame 1 with vertical guide grooves 2 on both sides. A pressure plate 3 is movably installed between the two guide grooves 2. A lifting mechanism is provided between the pressure plate 3 and the top of the frame 1. The lifting mechanism includes a lead screw 5 threaded to the middle of the top of the frame 1 and a handwheel 6 fixedly installed on the top of the lead screw 5. The bottom end of the lead screw 5 is rotatably connected to the middle of the pressure plate 3 through a bearing. The two ends of the pressure plate 3 are slidably connected to the guide grooves 2. A pressure rod 4 is symmetrically and vertically fixed to the bottom ends of both sides of the pressure plate 3. A limiting mechanism is provided at the bottom end of the pressure rod 4. The limiting mechanism includes connecting parts 7 horizontally fixed to the bottom end of the pressure rod 4. The bottom ends of the two connecting parts 7 on opposite sides are fixedly connected. There are vertical limit frames 8, and several guide rollers 9 are rotatably connected to the opposing sides of the two limit frames 8 through bearings. A roller conveyor 11 is set below the frame 1. There is a rotary positioning mechanism between the frame 1 and the roller conveyor 11. The rotary positioning mechanism includes a rotary mechanism and a positioning mechanism. The rotary mechanism includes a rotary adjustment shaft 10 rotatably connected to the bottom of both sides of the frame 1 through bearings. One end of the rotary adjustment shaft 10 is rotatably connected to the body of the roller conveyor 11 through bearings. The positioning mechanism includes positioning holes 13 opened on the roller conveyor 11 near the upper and lower ends of the rotary adjustment shaft 10. Locking screws 12 are threadedly connected to both sides of the frame 1 and near the upper end of the rotary adjustment shaft 10.

[0025] In this embodiment, the frame 1 is quickly folded and stored and unfolded and reset by the combined use of the lifting mechanism and the rotating positioning mechanism. This solves the technical problem in the prior art that the limiting device must be completely disassembled in order to adjust the production line layout, which significantly improves the equipment conversion efficiency and is particularly suitable for production lines that need to frequently switch production modes.

[0026] Furthermore, by alternating abutment between the limiting frame 8 and the upper and lower end faces of the roller conveyor 11, clamping and fixing are achieved in both the folded and working states, thereby improving the structural stability of the equipment during use and storage.

[0027] Working principle: When the frame 1 needs to be folded and stored, first turn the handwheel 6 to drive the lead screw 5 to rotate. Through the threaded engagement between the lead screw 5 and the frame 1, and the bearing connection between the bottom end of the lead screw 5 and the pressure plate 3, the pressure plate 3 is driven to rise along the guide groove 2. At the same time, the pressure rod 4 and its bottom limiting frame 8 are lifted as a whole, so that the limiting frame 8 is completely separated from the upper surface of the roller conveyor 11. At this time, the rotating adjustment shaft 10 can rotate freely under the support of the bearing. The operator flips the frame 1 180° downward around the rotating adjustment shaft 10 to below the roller conveyor 11. Then, the handwheel 6 is turned in the opposite direction to drive the lead screw 5 to reverse, so that the pressure plate 3 drives the limiting frame 8 to rise until the limiting frame 8 is tightly abutted against the lower surface of the roller conveyor 11 to achieve clamping and fixation. When it needs to be unfolded for use, turn the handwheel 6 again to lift the limiting frame 8 to separate it from the lower surface. After flipping the frame 1 back to above the roller conveyor 11, control the limiting frame 8 to descend until it abuts and is fixed against the upper surface of the frame.
