Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a novel trough servo conveying device. Background Technology

[0002] With social development and improved living standards, the market demand for bottled and canned packaging products in the fields of pharmaceuticals, food, and cosmetics has increased significantly year by year. The traditional production model, which relies heavily on manual labor for feeding, sorting, conveying, and packing, not only faces a growing labor shortage but also suffers from low production efficiency, high labor costs, and difficulties in personnel management, making it unsuitable for modern large-scale production. Therefore, upgrading and automating the production process has become an urgent need for related industries, and one of the core elements in achieving automated production lies in developing efficient, reliable, and precisely positioned automated conveying devices.

[0003] In existing production technologies, the conveying of bottle and can materials mostly adopts traditional belt conveyors, chain conveyors, or screw conveyors. However, in actual use, the following problems exist: First, the production cycle is slow, making it difficult to match the speed of high-speed filling and packaging equipment, thus becoming a bottleneck in the overall production efficiency. Second, the positioning function is poor, and materials are prone to accumulation, jamming, or uneven spacing during the conveying process, resulting in chaotic material posture and inconsistent spacing. This makes it impossible to provide stable and precise stopping positions for subsequent robotic gripping, boxing, and palletizing processes, severely restricting the realization of fully automated production. Utility Model Content

[0004] The purpose of this invention is to provide a novel trough servo conveying device that improves positioning accuracy and ensures consistent material spacing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel trough-type servo conveying device, comprising a frame, with synchronous pulley 1 and synchronous pulley 2 rotatably mounted at both ends of the frame; a synchronous belt 1 is drivingly connected between the two synchronous pulley 1s, and a synchronous belt 2 is drivingly connected between the two synchronous pulley 2s; multiple material baffles are evenly fixedly installed on the surfaces of the synchronous belt 1 and synchronous belt 2 along the conveying direction, and a trough for accommodating materials is formed between adjacent material baffles; a servo motor 1 for driving the synchronous pulley 1 to rotate and a servo motor 2 for driving the synchronous pulley 2 to rotate are fixedly mounted on the frame; both the servo motor 1 and servo motor 2 are electrically connected to an external PLC control system.

[0006] A further feature of this invention is that support plates for support and installation are fixedly provided on both sides of the frame.

[0007] A further feature of this invention is that a mounting shaft that is rotatably connected to the frame is fixedly provided in the middle of the synchronous pulley, and a transmission wheel is installed on one end of one of the mounting shafts and on the output shaft of the servo motor. The two transmission wheels are connected by a transmission belt.

[0008] A further feature of this invention is that a mounting shaft two, which is rotatably connected to the frame, is fixedly provided in the middle of the synchronous pulley two. A transmission wheel two is installed on one end of one of the mounting shaft two and on the output shaft of the servo motor two. The two transmission wheels two are connected by a transmission belt two.

[0009] A further feature of this invention is that, under the control of an external PLC control system, the first servo motor and the second servo motor can perform synchronous intermittent rotational motion or independent differential motion.

[0010] A further feature of this invention is that two material baffles are provided above the frame, and the material baffles are fixedly connected to the side of the frame via mounting brackets. The material baffles away from the front conveyor line are longer and correspond to the discharge end of the front conveyor line.

[0011] In summary, this utility model has the following beneficial effects: Through the precise coordination of two servo motors under the control of a programmable logic controller, this device can achieve high-speed intermittent motion, with a material conveying speed of over two hundred pieces per minute, greatly improving the overall production efficiency and effectively solving the problem of low efficiency of traditional conveying equipment becoming a production bottleneck. It perfectly matches the production rhythm of modern high-speed filling and packaging equipment. The use of servo motor drive, combined with the fixed-size partition formed by evenly spaced material baffles, ensures that each material can be accurately separated and positioned. The materials maintain a uniform gap throughout the conveying process, providing a stable and precise workstation for subsequent robotic gripping, boxing, and inspection processes. This fundamentally overcomes the drawbacks of traditional conveyor lines, such as material accumulation, jamming, and inconsistent spacing, and meets the stringent positioning accuracy requirements of fully automated production. While one synchronous belt is responsible for high-speed feeding to the gripping station, another synchronous belt can simultaneously and accurately reset the empty slot to the receiving station. This cyclical motion mode ensures that materials from the front-end conveyor line can enter the device uninterruptedly and continuously, realizing a true assembly line operation.

[0017] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0018] Please see Figures 1-4 In this embodiment of the present invention, a novel trough servo conveying device includes a frame 1, which is typically welded from profiles (such as aluminum profiles) or steel plates to ensure the rigidity of the overall structure. Support plates 101 are fixedly installed on both sides of the bottom of the frame 1 to support the entire device at a suitable working height and facilitate connection and fixation with other equipment on the production line.

[0019] Synchronous pulley 1 2 and synchronous pulley 2 3 are rotatably installed at both ends of the frame 1 along its length. Synchronous belt 1 201 is connected between the two synchronous pulleys 1 2, and synchronous belt 2 301 is connected between the two synchronous pulleys 2 3. Synchronous belt 1 201 and synchronous belt 2 301 are parallel to each other and constitute the main bearing surface for material conveying.

[0020] The servo motor 202 is fixed to the bottom of the frame 1 via a motor mounting plate. A mounting shaft 2, rotatably connected to the frame 1, is fixedly mounted in the middle of the synchronous pulley 2. A transmission wheel 1 is mounted on one end of one of the mounting shafts and on the output shaft of the servo motor 202. The two transmission wheels 1 are connected by a transmission belt 203. Similarly, the servo motor 302 is fixed to the front end of the frame 1 via a motor mounting plate. A mounting shaft 2, rotatably connected to the frame 1, is fixedly mounted in the middle of the synchronous pulley 3. A transmission wheel 2 is mounted on one end of one of the mounting shafts and on the output shaft of the servo motor 302. The two transmission wheels 2 are connected by a transmission belt 303. This driving method ensures precise and efficient power transmission.

[0021] On the surfaces of synchronous belt 201 and synchronous belt 301, multiple hopper partitions 4 are fixedly installed at even intervals along the conveying direction. The bottom of the hopper partitions 4 is fixed to synchronous belt 201 and synchronous belt 301 by bolts, and their vertical surfaces are perpendicular to the conveying plane. The space between two adjacent material baffles 5 forms a trough for accommodating materials such as bottles and cans. The width of the trough can be precisely designed according to the diameter of the material to ensure that each trough can only accommodate one material, thereby achieving material separation and precise positioning.

[0022] In this embodiment, preferably, to further optimize the material introduction process and prevent materials from falling or getting stuck from the side, two fixed material baffles 5 are provided above the frame 1 in the area between synchronous belt 1 201 and synchronous belt 2 301. These two material baffles 5 are fixedly connected to the side of the frame 1 by mounting brackets 501 and do not move with the synchronous belts. One material baffle 5 is located on the side closer to the front conveyor line (such as the pillow bag machine conveyor line), and is shorter in size, mainly playing a preliminary guiding role. The other material baffle 5 is located on the side away from the discharge end of the front conveyor line, and is longer in size. Its length direction corresponds fully to the inlet end, which can better receive and guide the materials from the front conveyor line, ensuring that the materials fall smoothly and accurately into the dynamic trough formed by the hopper partitions 4 on the moving synchronous belt.

[0023] In this embodiment, preferably, both servo motor 202 and servo motor 302 are connected to an external PLC (programmable logic controller) control system via cables; a photoelectric switch (not shown in the figure) is provided on the front conveyor line of the trough servo conveyor, and the photoelectric switch is also connected to the PLC control system signal.

[0024] In operation, a photoelectric switch is installed near the outlet of the front-end pillow bag conveyor line. When the material bottles pass by the photoelectric switch, the switch instantly generates a detection signal and transmits it to the PLC. Upon receiving this trigger signal, the PLC immediately sends pulse commands to servo motor 202 and servo motor 302 simultaneously according to a preset program. Servo motors 202 and 302 rotate synchronously by a precise, pre-calculated angle, which corresponds exactly to the distance between the moving slots of synchronous belts 201 and 301. Simultaneously, synchronous belts 201 and 301 advance one station, moving away the slot that has already received material and precisely moving an empty slot to the receiving station, aligning it with the outlet end of the front-end conveyor line. The process is repeated to prepare for receiving the next material. This process is repeated to achieve intermittent material reception and step-by-step movement. When the amount of material in a compartment reaches the preset layer quantity (i.e., the quantity that the robot can grab and pack in one go), the PLC will issue a new control command. At this time, servo motor 202 starts, driving synchronous pulley 2 and synchronous belt 201 to rotate rapidly, conveying the entire compartment full of material to the downstream robot grabbing station at high speed and with precision, waiting for the industrial robot to grab and pack the material. After the operation is completed, another servo motor 302, under the command and control of the PLC, drives synchronous pulley 3 and synchronous belt 301 to run rapidly, accurately resetting an empty compartment on it and positioning it to the front receiving station, ensuring that there is always an empty compartment ready at the receiving position.

[0025] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
