Description

TECHNICAL FIELD

[0001] The utility model relates to a label equipment technical field, concretely relates to a full -automatic feeding device for electric energy meter nameplate. BACKGROUND

[0002] In the current industrial automation field, small electronic labeling machine as the important equipment on the production line, its efficient, accurate labeling capacity is important to improve the overall production efficiency. Especially in the electronic product manufacturing process, electronic label is attached to all kinds of panel has become a part of the standardization process. At present, the feeding mode of panel at the entrance of small electronic labeling machine mainly follows two traditional modes: manual mode and semi-automatic mode.

[0003] Manual feeding mode depends on manual operation, that is, the panel to be labeled is placed manually on the material conveying track one by one, and then conveyed to the labeling operation area to complete the labeling operation. This mode is intuitive in operation, but the significant disadvantage is that a special operator is needed to be responsible for feeding, which not only causes waste of human resources, but also limits the improvement of production efficiency, especially in large-scale, continuous production scenarios, the problem of low efficiency is particularly prominent.

[0004] To solve the problem of human consumption of manual mode, the industry has developed a semi-automatic feeding system, which realizes the automatic connection of printing and labeling by directly integrating the code marking machine and the electronic labeling machine. Specifically, after the panel completes the two-dimensional code printing on the code marking machine, it is automatically transferred to the material conveying track of the electronic labeling machine, and then conveyed to the labeling position to complete the labeling. Although the semi-automatic mode improves the degree of automation to some extent, its inherent limitations cannot be ignored. This mode strictly requires that the panel must be labeled immediately after printing the two-dimensional code to realize seamless connection. However, in actual production process, there are often cases that the panel cannot be labeled immediately after printing or the panel is pre-printed when it is delivered, at which time the semi-automatic system cannot effectively cope with it and still needs manual intervention to complete the feeding and labeling, thereby weakening its automation advantage.

[0027] The material loading structure 1 includes material box 11 and material loading drive module 12, the material loading drive module 12 is controlled by PLC control system;

[0028] The material transport structure 3 includes first sliding block 31, material transport shaft 32 and servo motor 33 for driving the first sliding block 31, the first sliding block 31 is sleeved on the material transport shaft 32, and the material transport shaft 32 is arranged on the conveying belt;The servo motor 33 is controlled by PLC control system, and the material taking structure 2 is driven to reciprocate at the upper side of material box 11 and the upper side of electronic labeling machine conveying belt according to the pre-set speed, to complete material transport;

[0029] The material taking structure 2 includes material taking suction nozzle 21, second sliding block 22 and cylinder 23, the material taking suction nozzle 21 is slidably connected with the cylinder 23 by the sliding block 22;The material taking structure 2 is arranged on the first sliding block 31 by the cylinder 23;The cylinder 23 is controlled by PLC control system, for driving the material taking suction nozzle 21 to move up and down at the upper side of material box 11.

[0030] In a possible implementation, as shown in Figures 2-3 The hopper 11 includes a bottom plate 111, a movable baffle 112, a side plate 113 and a back plate 114. The bottom plate 111 is connected with the feeding driving module 12. The bottom plate 111 and the movable baffle 112 are connected through a spring 115. The side plate 113 is connected with a bolt hole 117 on the back plate 114 through a bolt 116. The bolt hole 117 is in a rectangular shape. The bolt 116 can move freely in the bolt hole 117. An anti-overflow baffle 118 is arranged on the side plate 113.

[0031] Through the above embodiment, in actual application, only the positions of the two side baffles 113 of the hopper 11 need to be adjusted to adapt to different sizes of the panel. The anti-overflow baffle 118 on the top of the hopper 11 can prevent the material from overflowing from the hopper, and at the same time, can ensure that the material suction nozzle cannot suck too much material when sucking the material, and can only suck one panel each time, so that each panel is sequentially conveyed to the labeling track.

[0032] In a possible implementation, the feeding driving module 12 includes a feeding shaft 121, a feeding shaft slider 122 sleeved on the feeding shaft 121 and a stepping motor 123. One side of the bottom plate 111 is connected with the feeding shaft slider 122. The stepping motor 123 drives the feeding shaft slider 122 to move up and down along the feeding shaft 121, thereby driving the material on the movable baffle 112 to move up and down, and limiting the movement height through the anti-overflow baffle 118.

[0033] Through the stepping motor 123 driving the feeding shaft slider 122 to move up and down along the feeding shaft 121, the movement height of the material on the movable baffle 112 can be accurately controlled. The stepping motor 123 can accurately control the rotation angle and the number of steps, which is converted to the movement of the feeding shaft slider 122, so that the height position of the material can be accurately positioned, meeting the accurate requirements of different processes on the height of the material. The feeding shaft slider 122 is sleeved on the feeding shaft 121, which plays a guiding and stabilizing role, ensuring that the material moves along the predetermined path during the rising or falling process, and improving the stability and reliability of the feeding process.

[0034] In a possible implementation, the PLC control system is arranged in the operation panel 4. The operation panel 4 is provided with an “feeding shaft descending” key 41 and an “feeding shaft ascending” key 42. The PLC control system is electrically connected with the stepping motor 123 in the feeding structure, the “feeding shaft descending” key 41 and the “feeding shaft ascending” key 42 on the operation panel, the air cylinder 23 in the material taking structure and the servo motor 33 in the material conveying structure.

[0035] The operation panel is provided with a "loading shaft lowering" key 41 and a "loading shaft raising" key 42, and an operator can directly control the raising and lowering of the loading shaft slider 122 through simple key operation, which reduces the learning cost of the operator, enables the operator to quickly get started, and improves the operation efficiency of the equipment; the PLC control system is arranged in the operation panel, and a plurality of key control functions are integrated on the operation panel, thereby realizing the centralized control of different structures (loading structure, material taking structure and material conveying structure) of the entire equipment. The operator does not need to switch between a plurality of dispersed control devices, but only needs to perform corresponding key operation on the operation panel to control each part of the equipment, thereby greatly improving the convenience and efficiency of operation.

[0036] The automatic loading device provided in the application only needs to place a certain amount of materials (panels) in the material box when the device starts to work. When the panels are placed in the material box, the operator long-presses the "loading shaft lowering" key on the operation panel, the PLC controls the step motor to drive the bottom baffle of the material box to automatically move to a suitable position. After the operator releases the "raising" key, a certain amount of panels are placed in the material box, and then the "loading shaft raising" key is long-pressed. The PLC controls the step motor to drive the bottom baffle of the material box to automatically rise. When the topmost panel is in close contact with the anti-overflow baffle at the top of the material box, the "raising" key is released, and the loading operation is completed.

[0037] After the loading is completed, the operator presses the "start" key on the operation panel, the PLC controls the servo motor to drive the material taking suction nozzle to automatically move to the top of the material box, and then controls the cylinder of the material taking suction nozzle to automatically move downward and take the panel. After the panel is taken by the suction nozzle, the cylinder rises to the starting position of the material conveying, and is ready to convey the panel.

[0038] When the material taking suction nozzle automatically completes the panel taking and is at the starting position of the material conveying, the PLC controls the servo motor to drive the material taking suction nozzle to move to the top of the conveying belt of the electronic labeling machine at a pre-set speed. Then the material taking suction nozzle automatically places the panel material on the conveying belt. After the material conveying is completed, the PLC controls the servo motor to drive the material taking suction nozzle to return to the top of the material box to repeat the material taking and conveying actions.

[0039] When the PLC controls the servo motor to drive the material taking suction nozzle to perform the material conveying action, the PLC also controls the step motor to drive the baffle at the bottom of the material box to move upward at a pre-set speed by a thickness of a panel, so that the next panel to be taken is raised to a position where it can be taken by the material taking suction nozzle.

[0040] In a possible implementation, the material conveying shaft 32 is further sleeved with a buffer spring. When the material taking suction nozzle vibrates or is impacted during the material taking and conveying, the buffer spring can absorb and slow down the vibration and impact energy, so as to prevent the materials from falling due to vibration or impact.

[0041] The buffer spring can absorb and dampen these vibrations and impact energy, avoid the material from the material suction nozzle due to excessive vibration or impact, help to ensure the integrity of the material during transportation, reduce the loss of material, improve the utilization rate of material in the production process, reduce the production cost; even if the material does not fall, the violent vibration or impact may cause a certain degree of damage to the material, affect its quality, the existence of the buffer spring can effectively reduce the influence, so that the material is transported in a more stable state, thereby ensuring the quality of the material and improving the qualified rate of products.

[0042] In a possible implementation, the movable baffle 112 is provided with an inductive head 119, which can detect the position of the material on the movable baffle in real time. When the PLC control system controls the cylinder 23 to drive the material suction nozzle to perform the material conveying action, the PLC control system simultaneously controls the step motor to drive the movable baffle at the bottom of the material box to move upward at a preset speed by the thickness of a material, so as to lift the next panel to be sucked to a position that can be sucked by the material suction nozzle.

[0043] The inductive head provides accurate position information for the PLC control system, so that the system can accurately control the operation of the step motor. According to the feedback of the inductive head, the step motor drives the movable baffle to move upward at a preset speed, ensuring that the height of each feeding is accurate. This precise feeding control helps to improve the success rate and efficiency of material taking, and ensures the stability and consistency of the production process.

[0044] In a possible implementation, the central position of the material box bottom plate 111 is provided with a photoelectric sensor. When the last material in the material box is sucked by the material suction nozzle, the photoelectric sensor is automatically triggered to send a lack of material signal to the PLC control system. After receiving the lack of material signal, the PLC control system automatically performs sound and light alarm to remind the operator to timely replenish the material box.

[0045] The application of the photoelectric sensor realizes the automatic detection and alarm of the lack of material, greatly reducing the number of times and workload of manual inspection. The operator can devote more time and energy to other important production links, improving the utilization efficiency of human resources.

[0046] In a possible implementation, the operation panel 4 is also provided with an "emergency stop" button, which is directly electrically connected with the PLC control system. When an emergency occurs during the operation of the device, the operator presses the "emergency stop" button, and the PLC control system immediately controls the step motor in the feeding structure, the servo motor and the cylinder in the material taking structure, and the servo motor in the material conveying structure to stop working.

[0047] The "emergency stop" button is arranged to enable the operator to press the button in the first time when facing danger, rapidly cut off the power source of the equipment, and stop the motors and air cylinders in the material feeding structure, material taking structure and material conveying structure from working, so that the risk of personnel casualty caused by emergency is greatly reduced.

[0048] The above is a specific description of the preferred embodiment of the utility model, but the utility model is not limited to the described embodiment, and various equivalent modifications or replacements can be made by those skilled in the art without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the application.
