Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer automatic winding machines with loading and unloading devices, in particular to an automatic transformer winding machine with a loading and unloading device with fool-proof measures. Background Art
[0002] All kinds of transformer automatic winding machines, whether high-frequency transformers or low-frequency transformer automatic winding machines, generally use skeletons. The enameled wires of each winding group are wound in the wire grooves specified by the skeleton, and the starting and winding wires are hung at different feet. The loading and unloading racks of the automatic winding machines in the prior art are not installed with material sensors. During normal operation, the skeletons that have just been wound on the spools are waiting for unloading. Workers must take away the goods that have been unloaded in the previous work cycle from the unloading position of the loading and unloading racks, and put the empty skeletons in the loading position of the loading and unloading device in the correct direction. , the worker presses the start button, the loading and unloading device drives the loading and unloading rack to move forward automatically, and then rises. The frame that has just been wound on the spool falls into the unloading position of the loading and unloading rack, and the loading and unloading rack resets backward. The front wall of the unloading position pulls the frame that has just been wound out of the spool backward. The loading and unloading rack moves to the left and moves forward again, aligns the empty frame with the spool, and the rear wall of the loading position pushes the empty frame forward into the spool. The loading and unloading rack descends, resets backward, and then resets to the right. The worker takes the goods from the unloading position of the loading and unloading rack and presses the start button again to start the next work cycle. This cycle repeats itself; however, production line workers often neglect to press the start button without taking away the materials from the previous work cycle in time. The loading and unloading device automatically unloads the materials step by step according to the above process, and the loading and unloading device moves forward and then rises. At this time, the skeleton that has not been unloaded from the previous work cycle at the unloading position of the loading and unloading rack will collide with the skeleton on the bobbin that is ready to be unloaded, and the product will be damaged and scrapped, which will increase the cost. Over a long period of time, the bobbin and the loading and unloading device will be deformed and cannot be used or even scrapped; in another case, although the goods at the unloading position of the loading and unloading rack are taken away in time, the worker forgets to put the skeleton on the loading position of the loading and unloading rack, and presses the start button. Although the loading and unloading device can automatically unload successfully, the bobbin is empty because there is no goods at the loading position. When winding, the guide needle cannot hang the wire on the skeleton, resulting in wire breakage, and the automatic machine idling, wasting time and reducing production efficiency; both situations are due to worker negligence: one is that the goods at the unloading position of the loading and unloading device are not taken away in time, and the other is that the loading position of the loading and unloading device is not replenished and released in time, which often occurs on the production line of this industry.
[0003] Therefore, in view of the existing problems in the prior art, it is urgently necessary to provide a transformer automatic winding machine with a loading and unloading device with fool-proof measures. Utility Model Content

[0008] Example 1: The loading and unloading rack has four unloading troughs, each corresponding to four unloading trough sensors; at the same time, there are four loading troughs, each corresponding to four loading trough sensors;
[0009] Example 2 The loading and unloading rack includes a discharge trough, a loading trough and a loading trough cavity, a spring, a guide hole, a guide rod, and a rear side wall; except for the rear side wall, there are four of the above, and the four discharge troughs are neatly arranged in a row, sharing a pair of discharge trough optical fiber sensors; four loading troughs are neatly arranged in a row, and the four share a pair of loading trough optical fiber sensors; a row of discharge troughs and a row of loading troughs are staggered front and back, the discharge trough queue is located at the rear side, and the loading trough queue is located at the front side;

[0014] Beneficial effects of the utility model:
[0015] (1) Example 1 of the present invention drills holes at the rear ends of all the unloading and loading positions of the loading and unloading racks to install unloading position sensors and loading position sensors, and logically associates them in the PLC program. When the unloading position sensor is on, pressing the start key is ineffective until the goods in the unloading chute are taken away and all the unloading position sensors are off, then pressing the start key is effective. At the same time, when all the loading position sensors are not on, pressing the start key is ineffective until all the loading positions are replenished and all the unloading position sensors are on, then pressing the start key is effective.
[0016] (2) In Example 2 of the present invention, all loading positions of the loading and unloading racks are designed to be inserts that can slide back and forth. Each loading position corresponds to a loading trough cavity. There is a spring between the rear wall of the loading position and the front wall of the loading trough cavity. The loading position can slide back and forth in the loading trough cavity. There is a loading trough in each loading position.
[0017] (3) The loading and unloading racks of Example 2 of the present invention are provided with a pair of loading optical fiber sensors installed on both sides of the rear end, and a pair of unloading optical fiber sensors installed on both sides of the front end, and their positions are fixed. When the spring is not compressed and deformed, a row of loading troughs and a row of unloading troughs are staggered front and back. When there is cargo in the unloading trough that is not removed in time, the unloading optical fiber sensor lights up. When all loading troughs are not replenished in time, the loading optical fiber sensor does not light up. For either of the two situations, pressing the start button will be ineffective no matter which one occurs.
[0018] (4) The inner dimensions of the loading trough cavity of Example 2 of the present invention are slightly larger than the loading trough, so that the loading trough can slide freely forward and backward in the loading trough cavity. The diameter of the guide hole on the rear side wall of the material rack is slightly larger than the outer diameter of the guide rod, so that the guide rod can move forward and backward in the guide hole.
[0019] (5) When the spring of Example 2 of the present invention is not compressed and deformed, a row of loading troughs and a row of unloading troughs can be staggered front and back, so that the loading optical fiber sensor and the unloading optical fiber sensor can be different inductively sensed and light up or not, and send corresponding sensing signals to the PLC respectively, so that the PLC can understand the various loading and unloading situations on site in real time and make targeted and correct processing.
[0020] (6) When the spring of Example 2 of the present invention is compressed and deformed, that is, when the upper and lower material racks are loading, the left and right moving piston rods of the front and rear cylinders on the left and right sides extend out, pushing the upper and lower material racks backward, and the front wall of the loading trough overcomes the elastic force of the spring and is closely aligned with the front wall of the loading trough cavity. A row of loading troughs and a row of unloading troughs are aligned front and back, and the inner holes of the empty skeletons of the loading troughs are aligned and inserted into the winding fixture, and the loading is completed; at the same time, the rear end of the spring is fixed to the front wall of the loading trough, and the front end is fixed to the front side wall of the material rack, which not only ensures that the spring will not escape from the upper and lower material racks, but also ensures that the loading trough will not escape backward from the loading trough cavity, and will only move back and forth within the loading trough cavity under the action of the spring.

[0050] (2) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to move backward, and the unloading position of the upper and lower material rack is directly below the frame;
[0051] (3) The lifting and moving device of the upper and lower material rack drives the upper and lower material rack upward, and the unloading skeleton falls into the unloading position of the upper and lower material rack;
[0052] (4) The upper and lower material rack forward and backward moving device drives the upper and lower material rack to reset forward; the rear wall 402 of the material rack unloading chute of Example 1 of the upper and lower material rack is also reset forward, and the skeleton to be unloaded is pulled forward out of the winding fixture 102;
[0053] (5) The upper and lower material racks forward and backward moving device drives the upper and lower material racks to move to the left, and the loading positions of the upper and lower material racks are aligned with the frame;
[0054] (6) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to move backward, aligning the inner hole of the empty skeleton to be wound at the upper material position of the upper and lower material rack with the winding fixture 102, and the rear wall 403 of the material rack loading slot of Example 1 pushes the skeleton backward, and the skeleton is inserted into the winding fixture 102;
[0055] (7) The lifting and moving device of the upper and lower material racks drives the upper and lower material racks to reset downward;
[0056] (8) The forward and backward moving device of the upper and lower material racks drives the upper and lower material racks to reset forward;
[0057] (9) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to reset to the right;
[0058] (10) Take out the wound bobbin from the unloading chute of the upper and lower material racks, place the empty bobbin to be wound into the loading chute in the correct direction, and press the start button to start the next working cycle.
[0059] Serious consequences of mistakes: If employees are negligent and forget to take out the wound bobbins in the discharge chute in time due to fatigue during work, and press the start button, the program will proceed step by step. In step 3, the load and unload racks move upward, and the wound bobbins in the discharge chute and the bobbins to be unloaded in the winding fixture collide with each other, killing each other and smashing all the wound bobbins, increasing the defective rate and material costs, and important spare parts such as the winding fixture and the load and unload racks are deformed or even scrapped, increasing maintenance costs; on the other hand, if the operator forgets to put the empty bobbins to be wound in the loading chute and presses the start button, there is no bobbin on the winding fixture, causing the wire to fall out of the guide needle and the machine to idle, reducing the effective utilization of the machine.
[0060] The effective foolproof measures in this example are: sensors X001, X002, X003, and X004 are installed in the four unloading troughs, sensors X005, X006, X007, and X008 are installed in the four loading troughs, the start button on the touch screen corresponds to X011, the stop button on the touch screen corresponds to X012, and a work cycle loading and unloading process group Y001 is executed. The program ladder diagram is as follows:
[0061]
[0062] Before the improvement, as long as the start key 1081 X011 on the touch screen 108 is pressed, the entire loading and unloading program group Y001 is triggered and self-locked, but because there is no sensor monitoring, abnormal loading and unloading of materials cannot be prevented. After pressing the start key X011, the program proceeds step by step, and it crashes when it should and breaks the line when it should.
[0063] After the improvement, if there is material in the four unloading troughs, the sensors X001, X002, X003, and X004 are on, and their break contacts are disconnected. Therefore, although the operator presses the start button X011, the Y001 action will not be executed; by the same token, if the loading trough is not replenished in time, the sensors X005, X006, X007, and X008 are not on, so although the operator presses the start button X011, the Y001 action will not be executed. When the worker presses the start button many times, the automatic winding machine will not execute. The worker will check the material loading and unloading conditions of the upper and lower troughs, correct the errors, press the start button, and the machine will run automatically.
[0064] Example 2
[0065] The automatic winding machine, automatic winding machine, auxiliary device, and loading and unloading rack driving device of Example 2 are the same as those of Example 1 and need not be described here. The difference is the loading and unloading racks.
[0066] like Figure 7, Example 2 The loading and unloading rack 501 includes four sets of unloading troughs, loading troughs and loading trough cavities 505, springs 502, guide holes 503, guide rods 504 and a rack front side wall 509, unloading trough optical fiber sensors X009 and loading trough optical fiber sensors X010; except for the front side wall of the rack, there are four of the above, the unloading trough is located on the front side, and the loading trough is located on the back side; each loading trough has a guide rod 504 on the front side; the front side of the upper and lower racks has a rack front side wall 509, on which there are four equidistant guide holes 503, each spring 502 is sleeved on the guide rod 503, and is respectively installed between the front wall of each loading trough and the front side wall of the rack, and the two ends of the spring are fixedly connected; each loading trough can slide freely back and forth in its respective loading trough cavity.
[0067] like Figure 8 In Example 2, the first, second, third and fourth unloading troughs of the material rack are 5011, 5012, 5013, 5014 respectively; the first, second, third and fourth loading troughs of the material rack are 5015, 5016, 5017, 5018 respectively; the first, second, third and fourth loading trough cavities of the material rack are 5055, 5056, 5057, 5058 respectively; each loading trough has a guide rod 504 on the front side. The front side of the upper and lower material rack 501 has a material rack front side wall, on which there are four equally spaced guide holes 503 that are directly opposite to the four material loading slots. The guide rod 504 can move freely forward and backward in the guide hole 503, but it does not separate. There are four springs 502, each of which is installed between the material loading slot and the front side wall of the material rack, and the two ends are fixedly connected; at the same time, the four material loading slots 5015, 5016, 5017, 5018 can slide freely forward and backward in their respective material loading slot cavities 5055, 5056, 5057, 5058. When the spring 502 is not compressed, the spring pushes the respective material loading slot forward and backward, so that all the material loading slots and all the unloading slots are misaligned front and back.
[0068] The winding method of the automatic winding machine with fool-proof measures in the present embodiment includes the following main steps:
[0069] (1) The skeleton winding of the winding fixture 102 is completed and waiting for unloading;
[0070] (2) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to move backward, and the unloading position of the upper and lower material rack is directly below the frame;
[0071] (3) The lifting and moving device of the upper and lower material rack drives the upper and lower material rack upward, and the unloading skeleton falls into the unloading position of the upper and lower material rack;
[0072] (4) The upper and lower material rack forward and backward moving device drives the upper and lower material rack to reset forward; the rear wall 506 of the material rack unloading chute of Example 2 of the upper and lower material rack is also reset forward, and the skeleton to be unloaded is pulled forward out of the winding fixture 102;
[0073] (5) The upper and lower material racks forward and backward moving device drives the upper and lower material racks to move to the left, and the loading positions of the upper and lower material racks are aligned with the frame;
[0074] (6) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to move backward, aligning the inner hole of the empty skeleton to be wound at the loading position of the upper and lower material rack with the winding fixture 102. At this time, the spring 502 is compressed, and each loading trough overcomes the elastic force of the spring 502 and slides forward in its respective loading trough cavity 505. The guide rod 504 of each loading trough passes forward from the respective guide hole 503 on the rear side wall 509 of the material rack of Example 2. When the rear wall 507 of the loading trough of Example 2 and the rear wall 508 of the loading trough cavity of Example 2 fit together, all the unloading troughs are aligned with the loading trough, and the rear wall 507 of the loading trough of Example 2 pushes the skeleton backward, and the skeleton is inserted into the winding fixture 102.
[0075] (7) The lifting and moving device of the upper and lower material racks drives the upper and lower material racks to reset downward; each loading trough slides backward in its own loading trough cavity 505 under the elastic force of the spring 502, the spring 502 stretches to the longest, and the positions of all loading troughs and unloading troughs are restored to be staggered front and back;
[0076] (8) The forward and backward moving device of the upper and lower material racks drives the upper and lower material racks to reset forward;
[0077] (9) The forward and backward moving device of the upper and lower material rack drives the upper and lower material rack to reset to the right;
[0078] (10) Take out the wound bobbin from the unloading chute of the upper and lower material racks, place the empty bobbin to be wound into the loading chute in the correct direction, and press the start button to start the next working cycle.
[0079] Serious consequences of mistakes: If employees are negligent and forget to take out the wound bobbins in the discharge chute in time due to fatigue during work, and press the start button, the program will proceed step by step. In step 3, the load and unload racks move upward, and the wound bobbins in the discharge chute and the bobbins to be unloaded in the winding fixture collide with each other, killing each other and smashing all the wound bobbins, increasing the defective rate and material costs, and important spare parts such as the winding fixture and the load and unload racks are deformed or even scrapped, increasing maintenance costs; on the other hand, if the operator forgets to put the empty bobbins to be wound in the loading chute and presses the start button, there is no bobbin on the winding fixture, causing the wire to fall out of the guide needle and the machine to idle, reducing the effective utilization of the machine.
[0080] The effective foolproof measures in this example are: a pair of fiber optic sensors X009 are installed on the left and right sides of the four unloading troughs, and a pair of fiber optic sensors X010 are installed on the left and right sides of the four loading troughs. The button corresponding to the start key of the touch screen is X011, and the button corresponding to the stop key of the touch screen is X012. The loading and unloading process group Y001 is executed in a working cycle. The program ladder diagram is as follows:
[0081]
[0082] Before the improvement, as long as the start key 1081 X011 on the touch screen 108 is pressed, the entire loading and unloading program group Y001 is triggered and self-locked, but because there is no sensor monitoring, abnormal loading and unloading of materials cannot be prevented. After pressing the start key X011, the program proceeds step by step, and it crashes when it should and breaks the line when it should.
[0083] After the improvement, if there is material in the four unloading troughs, the X009 fiber optic sensor will light up, and their break contacts will be disconnected. Therefore, although the operator presses the start key X011, the Y001 action will not be executed; by the same token, if there is no material in all the loading troughs, the X010 fiber optic sensor will not light up, so although the operator presses the start key X011, the Y001 action will not be executed. When the worker presses the start key multiple times, the automatic winding machine will not execute. The worker will consciously check the material loading and unloading conditions of the loading and unloading troughs, correct the errors, press the start key, and the machine will run automatically.
[0084] Example 3
[0085] The main technical scheme of this embodiment is basically the same as that of embodiment 1. The features not explained in this embodiment adopt the explanation in embodiment 1 and will not be repeated here. Multiple automatic winding machines of this embodiment are chained in series, which is suitable for multiple windings of a transformer. Each automatic winding machine has an upper and lower material rack. There is a multi-axis slide between each two adjacent automatic winding machines to transfer semi-finished wire packages between the two machines in sequence. A sensor can also be installed on the unloading trough and the loading trough of the upper and lower material racks of each automatic winding machine to monitor the material arrival status of each slot. When an abnormality occurs, an alarm will be automatically triggered, and the operation of the automatic winding machine will be automatically suspended immediately until the operator eliminates the abnormality and the materials in the unloading trough and the loading trough of the upper and lower material racks are normal. Only then can the alarm be eliminated and the start button can be pressed to resume the normal continuous operation mode.
[0086] Finally, it should be noted that the above embodiments only use a four-axis automatic winding machine as an example. The principle of installing sensors on the unloading chute and loading chute of the upper and lower material racks to monitor whether the material arrival is abnormal is also applicable to the 8-axis machine, 10-axis machine, 12-axis machine, 16-axis machine and other automatic winding machines that are currently popular in the market. The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the scope of protection of the claims; ordinary technicians in this field should understand with reference to the preferred embodiments, and can modify or replace the technical solution of the utility model with equivalents, but they belong to the same substance and protection scope of the technical solution of the utility model.
