Description

Technical Field

[0001] This utility model relates to the field of automation technology, specifically to an automatic tank discharge mechanism for square tanks. Background Technology

[0002] In the food and beverage canning industry, after square cans are produced, arranging them into a neat rectangular array and transporting them to subsequent processes for palletizing is a key step in ensuring efficient production.

[0003] In this step, some manufacturers still rely on manual operation. Workers must manually arrange the square cans output from the production line into a rectangular array one by one. This is not only extremely labor-intensive but also inefficient, making it difficult to meet the needs of large-scale production. Manual arrangement is also prone to can positional deviations and irregular arrays, making it difficult to stack them accurately during subsequent palletizing, increasing the palletizing error rate, and even affecting packaging quality and production progress. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic can-discharging mechanism for square cans in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an automatic can-discharging mechanism for square cans, including a frame. A collecting conveyor belt and an input conveyor belt are fixedly connected to the frame. The length direction of the input conveyor belt is perpendicular to the length direction of the collecting conveyor belt. A moving component is fixedly connected to the frame. The moving component includes a connecting plate that moves along the length direction of the collecting conveyor belt. The connecting plate is fixedly connected to an mounting plate via a lifting cylinder. A can-fixing groove is fixedly connected to the bottom of the mounting plate for receiving square cans conveyed by the input conveyor belt and arranging several square cans along the width direction of the collecting conveyor belt.

[0007] A blocking component is fixedly connected to one end of the input conveyor belt near the collecting conveyor belt to prevent the square cans on the input conveyor belt from moving onto the collecting conveyor belt.

[0008] The aforementioned automatic can-stacking mechanism for square cans moves the square cans produced on the production line along the width of the collection conveyor belt via the input conveyor belt and inserts them into the corresponding can-stacking slots. A moving component moves the mounting plate so that another can-stacking slot aligns with the input conveyor belt, allowing subsequent square cans to fill that slot. When the moving component adjusts the position of unfilled square cans, a blocking component stops the square cans moving from the input conveyor belt onto the collection conveyor belt. This process is repeated until all can-stacking slots are filled. Then, a lifting cylinder moves the mounting plate and the can-stacking slots upwards, detaching the slots from the square cans. At this point, the square cans on the upper side of the collection conveyor belt will be arranged in a rectangular array, facilitating subsequent stacking. The collection conveyor belt then moves these arranged square cans to the next process.

[0009] Preferably, the blocking component includes an electric push rod fixedly connected to the input conveyor belt, with a top plate fixedly connected to the movable end of the electric push rod. Two guide plates are fixedly connected to the upper side of the input conveyor belt, and the two guide plates are arranged along the length direction of the input conveyor belt to guide the moving square can. The top plate corresponds to one of the guide plates, and the top plate and the corresponding guide plate cooperate to clamp the square can.

[0010] Preferably, the spacing between the two guide plates and the width of the input conveyor belt are adapted to the width of the square can.

[0011] Preferably, there are several can fixing slots, all of which are fixedly connected to the mounting plate along the width direction of the collecting conveyor belt.

[0012] Preferably, the width of the can fixing groove is adapted to the width of the square can, and the can fixing groove can only accommodate a single row of square cans distributed in a straight line. The can fixing groove corresponds to the upper side of the collection conveyor belt.

[0013] Preferably, the upper side of the collecting conveyor belt is flush with the upper side of the input conveyor belt.

[0014] Preferably, the moving component includes two upright plates fixedly connected to the frame, two parallel guide rods fixedly connected between the two upright plates, a connecting plate slidably connected between the two guide rods, a lead screw rotatably connected between the two upright plates, a connecting block threaded onto the lead screw, the connecting block being fixedly connected to the connecting plate, and a motor fixedly connected to either of the upright plates, with the motor output shaft fixedly connected to the end of the lead screw for rotating the lead screw.

[0015] Preferably, there are four lifting cylinders, which are fixedly connected to the four corners of the connecting plate, and the movable ends of the four lifting cylinders are fixedly connected to the mounting plate.

[0016] Preferably, the connecting plate has holes on both sides, and guide rods are slidably connected in the holes.

[0017] Preferably, the guide rod and the lead screw are both arranged along the length of the collecting conveyor belt, and the width of the collecting conveyor belt is greater than or equal to the length of the can fixing trough.

[0018] The beneficial effects are:

[0019] 1. Through the coordinated operation of components such as the input conveyor belt, moving components, blocking components, and can-holding troughs, automated rectangular array arranging of square cans after they exit the production line is achieved. The input conveyor belt transports the cans to the designated position, and the moving components drive the can-holding troughs to receive and precisely position the cans. The blocking components control the conveying rhythm of the cans, ensuring that each can accurately falls into the trough and is neatly arranged along the width of the collection conveyor belt. After leaving the troughs, the square cans on the collection conveyor belt can quickly form a regular rectangular array. Compared with manual arrangement, efficiency is greatly improved, and the array regularity is high, fully meeting the arrangement accuracy requirements of subsequent palletizing processes.

[0020] 2. The rectangular array of square cans arranged in this device maintains a stable and neat distribution on the collection conveyor belt, allowing for seamless direct transport to the palletizing process. The orderly rectangular array enables the palletizing robotic arm to quickly and accurately grasp and stack the cans without requiring manual repositioning, greatly improving palletizing efficiency and accuracy, reducing palletizing errors and product damage, and ensuring the efficient and stable operation of the entire production process.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-3 As shown, this utility model provides an automatic can-discharging mechanism for square cans, including a frame 1. A collection conveyor belt 2 and an input conveyor belt 3 are fixedly connected to the frame 1. The length direction of the input conveyor belt 3 is perpendicular to the length direction of the collection conveyor belt 2. A moving component 4 is fixedly connected to the frame 1. The moving component 4 includes a connecting plate 13 that moves along the length direction of the collection conveyor belt 2. The connecting plate 13 is fixedly connected to an mounting plate 6 via a lifting cylinder 5. A can-fixing groove 7 is fixedly connected to the bottom of the mounting plate 6 for receiving square cans conveyed by the input conveyor belt 3 and arranging several square cans along the width direction of the collection conveyor belt 2.

[0029] An obstruction component 14 is fixedly connected to one end of the input conveyor belt 3 near the collecting conveyor belt 2 to prevent the square cans on the input conveyor belt 3 from moving onto the collecting conveyor belt 2.

[0030] A photoelectric sensor is installed near the can inlet of the input conveyor belt 3 as a counting device. When a square can passes the photoelectric sensor, the sensor detects that the can is blocking the light and generates a change in electrical signal. This electrical signal is transmitted to the control system. The counting module in the control system processes the signal and counts it. The count value is incremented by 1 for each can that passes through.

[0031] The moving component 4 drives the can-fixing slots 7 to sequentially receive and precisely position the cans. The blocking component 14 controls the can conveying rhythm, ensuring that each can accurately falls into the can-fixing slot 7 and is neatly arranged along the width of the collection conveyor belt 2. Specifically, when the counting module reaches the preset number of cans per row (e.g., 5), the control system sends a signal to the moving component 4, driving it to move the can-fixing slots 7 one slot's width perpendicular to the collection conveyor belt 2, preparing for the next row of cans. Simultaneously, the control system sends a command to the blocking component 14, causing it to stop obstructing the cans, allowing the next batch of cans to enter the arrangement area. After leaving the fixed slots, the square cans on the collection conveyor belt 2 can quickly form a regular rectangular array. Compared to manual arrangement, this significantly improves efficiency and produces a highly regular array, fully meeting the accuracy requirements of subsequent palletizing processes. When the total number of cans counted by the counting module reaches the preset number of palletizing batches (e.g., 100 cans, or 20 rows), the control system sends a signal to the collection conveyor belt 2 to pause its operation and wait for the palletizing robotic arm to complete the grabbing and stacking of that batch of cans.

[0032] Precise position control is achieved using a photoelectric sensing positioning system. Multiple photoelectric sensors are installed at intervals along the movement path of the can-fixing slot 7 on the frame 1. Their installation positions correspond one-to-one with the required stopping position of the can-fixing slot 7 after each row of cans is arranged. Each photoelectric sensor is connected to the control system. A light-shielding plate fixed to the can-fixing slot 7 passes sequentially past each photoelectric sensor. When the light-shielding plate blocks the light from the photoelectric sensor, the sensor generates a change in electrical signal, which is transmitted to the control system. After receiving the signal, the control system compares it with preset positioning parameters to determine whether the can-fixing slot 7 has reached the target position.

[0033] As an optional implementation, the blocking component 14 includes an electric push rod 15 fixedly connected to the input conveyor belt 3. The movable end of the electric push rod 15 is fixedly connected to a top plate 16. Two guide plates 17 are fixedly connected to the upper side of the input conveyor belt 3, and the two guide plates 17 are arranged along the length direction of the input conveyor belt 3 for guiding the moving square can. The top plate 16 corresponds to one of the guide plates 17, and the top plate 16 and the corresponding guide plate 17 cooperate to clamp the square can.

[0034] The top plate 16 is moved by the electric push rod 15, so that the top plate 16 is close to the corresponding guide plate 17 to clamp the current square can, so that the can on the input conveyor belt 3 stops moving onto the collection conveyor belt 2.

[0035] The spacing between the two guide plates 17 and the width of the input conveyor belt 3 are adapted to the width of the square can.

[0036] There are several can fixing slots 7, and they are all fixedly connected to the mounting plate 6 along the width direction of the collecting conveyor belt 2.

[0037] The width of the can fixing groove 7 is adapted to the width of the square cans, and the can fixing groove 7 can only accommodate a single row of square cans distributed in a straight line. The can fixing groove 7 corresponds to the upper side of the collection conveyor belt 2.

[0038] The upper side of the collecting conveyor belt 2 is flush with the upper side of the input conveyor belt 3. This design allows the square cans to be smoothly moved from the input conveyor belt 3 to the collecting conveyor belt 2.

[0039] The moving component 4 includes two upright plates 8 fixedly connected to the frame 1. Two parallel guide rods 9 are fixedly connected between the two upright plates 8. A connecting plate 13 is slidably connected between the two guide rods 9. A lead screw 10 is rotatably connected between the two upright plates 8. A connecting block 12 is threaded onto the lead screw 10. The connecting block 12 is fixedly connected to the connecting plate 13. A motor 11 is fixedly connected to either upright plate 8. The output shaft of the motor 11 is fixedly connected to the end of the lead screw 10 for rotating the lead screw 10.

[0040] The motor 11 rotates the lead screw 10, which drives the connecting block 12 via its thread, causing the connecting block 12 to move the connecting plate 13 along the length of the collection conveyor belt 2.

[0041] There are four lifting cylinders 5, which are fixedly connected to the four corners of the connecting plate 13, and the movable ends of the four lifting cylinders 5 are fixedly connected to the mounting plate 6. This distribution makes the lifting of the mounting plate 6 more stable.

[0042] The connecting plate 13 has holes on both sides, and guide rods 9 are slidably connected in the holes;

[0043] The two guide rods 9 work together to guide the connecting plate 13, enabling it to move stably along a straight line.

[0044] Guide rod 9 and lead screw 10 are both set along the length of the collection conveyor belt 2, and the width of the collection conveyor belt 2 is greater than or equal to the length of the can fixing groove 7. This design can ensure that the collection conveyor belt 2 can fully support all the square cans.

[0045] Using the above structure, the square cans produced on the production line are moved along the width of the collection conveyor belt 2 by the input conveyor belt 3 and inserted into the corresponding can fixing slot 7. The mounting plate 6 is moved by the moving component 4 so that another can fixing slot 7 corresponds to the input conveyor belt 3, so that the subsequent square cans fill the can fixing slot 7. When the position of the square cans that are not filled is adjusted by the moving component 4, the square cans moving from the input conveyor belt 3 to the collection conveyor belt 2 are stopped by the blocking component 14. The above steps are repeated until all the can fixing slots 7 are filled with cans. Then, the mounting plate 6 and the can fixing slots 7 are moved upward by the lifting cylinder 5 so that the can fixing slots 7 are separated from the square cans. At that time, the square cans on the upper side of the collection conveyor belt 2 will be distributed in a rectangular array, which is convenient for subsequent stacking. The collection conveyor belt 2 can move these arranged square cans to the next process.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
