Description

Technical Field

[0001] This utility model relates to the field of material distribution technology, specifically to an automated production line that improves release efficiency. Background Technology

[0002] The efficiency of downstream processes in an industrial automated production line can affect upstream processes (especially when there are multiple branches of the same downstream process). Inappropriate allocation often leads to some downstream processes being overloaded while others are idle, resulting in material transport stagnation in upstream processes. A reasonable allocation method can ensure that downstream processes are fully involved in the work, and upstream processes can more effectively avoid material stagnation.

[0003] Existing automated production lines have the following drawbacks:

[0004] 1. The existing automated production line adopts the method of releasing one by one (executed by the lifting and lowering of the lifting and stopping mechanism). This repetitive release method wastes time and results in low efficiency of upstream material conveying.

[0005] 2. The counting method is based on the cumulative number of times the coil of the lifting and stopping mechanism's cylinder is energized (the energization and de-energization of the solenoid valve coil of the stopping cylinder controls the lifting and stopping mechanism's movement; the lifting and stopping mechanism rises when the solenoid valve is energized and descends when de-energized). On the one hand, due to the short material spacing when the lifting and stopping mechanism releases materials, several materials may pass through at once, resulting in a low system count and excessive material being placed in the release channel, causing subsequent channel congestion. On the other hand, some materials may fail to pass through due to jamming when the stopping mechanism is raised, causing the upstream sensor to detect no material, resulting in the stopping mechanism not releasing materials for a long time, causing material jamming in the previous process. All of these situations will also reduce efficiency.

[0006] 3. Switching the swing arm (the swing arm device is a long swing arm that switches the material inflow channel by swinging the swing arm angle). The current situation is that when the count of the second rear channel of the system is reached, it is necessary to switch the swing arm to switch to the first rear channel. At the same time, the lifting and stopping mechanism of the channel is still releasing one by one. It is necessary to rely on the swing arm to forcibly push the material in contact with the swing arm to the first rear channel or the front channel. Since the existing swing arms are generally straight rods and the material is round, when they come into contact, the straight rod and the round shape make line-surface contact (the contact area is small). Forcibly pushing the material can easily cause the material to tip over. Utility Model Content

[0007] This utility model aims to solve the above-mentioned technical problems by providing an automated production line that improves release efficiency. The automated production line uses an arc-shaped push rod to push the material, which is less likely to cause the material to tip over. It uses a first rear channel sensor and a second rear channel sensor to detect whether there is material on the first rear channel and the second rear channel, and controls the lifting and stopping mechanism of the front channel to release the material and switch the swing arm to improve release efficiency.

[0008] To solve the above-mentioned technical problems, the present invention provides a technical solution for an automated production line that improves release efficiency:

[0009] The system includes a front channel and a first and a second rear channel located at the end of the front channel; the second rear channel is located behind the first rear channel; both the first and second rear channels are perpendicular to the front channel; each of the front, first, and second rear channels is equipped with a lifting and stopping mechanism, and a PLC controller is also included. A swing arm device is connected to the side of the front channel; the swing arm device includes a swing arm and a control box for controlling the swing of the swing arm; the control box is installed on the side of the front channel, and the swing arm is connected to the control box; the second rear channel has a guide connecting rod connected to its end near the front channel for guiding materials onto itself; a front sensor is installed on the front channel; a first rear sensor is installed on the first rear channel; a second rear sensor is connected to the second rear channel; an arc-shaped push rod for pushing materials is connected to the end of the swing arm; the control box, the three lifting and stopping mechanisms, the front sensor, the first rear sensor, and the second rear sensor are all connected to the PLC controller.

[0010] The arc-shaped push rod is hinged to the rocker arm via a rotating shaft, and a limit device is connected between the arc-shaped push rod and the rocker arm.

[0011] The limiting device includes a locking nut; the arc-shaped push rod has an arc-shaped limiting groove coaxial with the rotating shaft; the rocker arm is connected to a threaded connecting rod; the upper end of the threaded connecting rod passes through the arc-shaped limiting groove and is threadedly connected to the locking nut.

[0012] The guide connecting rod is inclined at an angle of 45 degrees.

[0013] The guide connecting rod is fixed to the second rear channel by bolts.

[0014] The front sensor is installed in front of the lifting and stopping mechanism of the front channel; the first rear sensor is installed in the first rear channel near the end of the front channel; the second rear sensor is installed in the second rear channel near the end of the front channel.

[0015] The technical effects that this utility model can achieve are:

[0016] 1. This utility model uses front-end sensors, first rear-end sensors, and second rear-end sensors to determine the material status and select the release channel, avoiding channel congestion in subsequent production processes caused by errors in the counting program.

[0017] 2. The lifting and stopping mechanism of the front channel adopts a continuous release method, which reduces the time wasted caused by the lifting and stopping mechanism releasing one by one, and can greatly improve the release efficiency of the front process.

[0018] 3. In the process of the rocker arm switching from the second rear channel to the first rear channel, if there is round material on the arc-shaped push rod, the round material will be pushed onto the first rear channel by the arc-shaped push rod. The round material and the arc-shaped push rod are in surface contact (which increases the contact area), and the round material is not easy to tip over during the pushing process.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] See Figures 1 to 9 .

[0027] An automated production line for improving release efficiency includes a front channel 1 and a first rear channel 2 and a second rear channel 3 located at the end of the front channel 1. The second rear channel 3 is located behind the first rear channel 2, and both the first and second rear channels 2 and 3 are perpendicular to the front channel 1. Lifting and stopping mechanisms 4 are installed on the front channel 1, the first rear channel 2, and the second rear channel 3. A PLC controller is also included. A swing arm device is connected to the side of the front channel 1. The swing arm device includes a swing arm 5 and a control box 6 for controlling the swing of the swing arm 5. The control box 6 is installed on the side of the front channel 1, and the swing arm 5 is connected to the control box 6. A guide connecting rod 7 for guiding materials onto itself is connected to the end of the second rear channel 3 near the front channel 1. Specifically, the guide connecting rod 7 is inclined at an angle of 45 degrees. More specifically, the guide connecting rod 7 is fixed to the second rear channel 3 by bolts. This utility model refers to the material conveying process... Figure 2 When the swing arm 5 is in the solid line position, the material is conveyed to the first rear channel 2 through the swing arm 5; when it is necessary to send the material to the second rear channel 3, the swing arm 5 can be controlled to move to the dotted line position through the control box 6.

[0028] A front-end sensor 8 is installed on the front channel 1, and a first rear-end sensor 9 is installed on the first rear channel 2; a second rear-end sensor 10 is connected to the second rear channel 3. Specifically, the front-end sensor 8 is installed in front of the lifting and stopping mechanism 4 of the front channel 1, the first rear-end sensor 9 is installed in the first rear channel 2 near the end of the front channel 1, and the second rear-end sensor 10 is installed in the second rear channel 3 near the end of the front channel 1; an arc-shaped push rod 11 for pushing materials is connected to the end of the swing arm 5; the control box 6, the three lifting and stopping mechanisms 4, the front-end sensor 8, the first rear-end sensor 9, and the second rear-end sensor 10 are all connected to the PLC controller, and the control box 6, the three lifting and stopping mechanisms 4, the front-end sensor 8, the first rear-end sensor 9, and the second rear-end sensor 10 are controlled by the PLC controller.

[0029] This utility model features an arc-shaped push rod 11 connected to the end of the rocker arm 5 for pushing materials. During the process of the rocker arm 5 switching from the second rear channel 3 to the first rear channel 2 (see reference...), Figure 2 (That is, during the process of the swing arm 5 cutting from the dotted line position to the solid line position), if there is a round material on the arc-shaped push rod 11, the round material will be pushed onto the first rear channel 2 by the arc-shaped push rod 11. The round material and the arc-shaped push rod 11 are in surface contact, and the round material is not easy to tip over during the pushing process.

[0030] In the setting of the lifting and stopping mechanism 4 of the front channel 1, the lifting and stopping mechanism 4 of the front channel 1 no longer uses the operation mode of one-up and one-down release when releasing materials. When the release conditions are met, the method of continuous release is adopted (the lifting and stopping mechanism 4 on the front channel 1 is always in the lowering state when releasing, and the materials are released one by one) until the first rear channel 2 and the second rear channel 3 are full of materials. Then the lifting and stopping mechanism 4 on the front channel 1 rises again, and the material release efficiency is significantly accelerated.

[0031] This invention no longer performs a counting function, but only uses the first rear channel sensor 9 and the second rear channel sensor 10 to detect the presence or absence of materials on the first rear channel 2 and the second rear channel 3, and controls the lifting and stopping mechanism 4 of the front channel 1 to release and switch the swing arm 5, thereby improving the overall work efficiency.

[0032] Preferably, the arc-shaped push rod 11 is hinged to the rocker arm 5 via a rotating shaft 12, and a limiting device is connected between the arc-shaped push rod 11 and the rocker arm 5. Specifically, the limiting device includes a locking nut 13, an arc-shaped limiting groove 14 coaxial with the rotating shaft 12 is provided on the arc-shaped push rod 11, and a threaded connecting rod 15 is connected to the rocker arm 5. The upper end of the threaded connecting rod 15 passes through the arc-shaped limiting groove 14 and is threadedly connected to the locking nut 13. With the above-mentioned connection structure, the rocker arm 5 can rotate around the rotating shaft 12 to adjust its position as needed. Specifically, when the rocker arm 5 needs to be adjusted, the locking nut 13 is loosened, and the rocker arm 5 can rotate around the rotating shaft 12. When it rotates to the desired position, the locking nut 13 is tightened, and the friction between the locking nut 13 and the arc-shaped push rod 11 is used to limit the arc-shaped push rod 11.

[0033] This invention relates to the program control of a PLC controller (see reference). Figure 5-9 The two channels have priority in their release, i.e.

[0034] 1. If the second downstream sensor 10 of the second downstream channel 3 does not detect material within a set time, the second downstream sensor 10 will be allowed to pass first, regardless of whether the first downstream sensor 9 of the first downstream channel 2 has detected material.

[0035] 2. If the second downstream sensor 10 does not detect material within the set time, and the first downstream sensor 9 of the first downstream channel 2 does not detect material within the set time, then the first downstream channel 2 will be allowed to pass.

[0036] The lifting and stopping mechanism 4 of the front channel 1 in this program will only rise in the initial state and when both channels show full material (both channels showing full material means that both the first rear channel 2 and the second rear channel 3 are full material), and when switching from the second rear channel 3 to the first rear channel 2, to cut off the material flow to the subsequent channel. In other states, it is in the release state. This release logic ensures the release efficiency of the front process and reduces the waiting time of the rear process.

[0037] At the same time, the switching frequency of the sway arm 5 position is also significantly reduced. The switching logic relies on the material detection of the sensors in the channel to control whether the channel is full or not. The channel will only be switched when one channel is full and the other channel is not full, thus avoiding the waste of time caused by frequent switching due to the original counting.
