DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, Figure 1 The utility model is a schematic structural diagram of an automatic bulb flat steel flipping and stacking machine according to an embodiment of the utility model.

[0022] In the figure, an automatic bulb flat steel flipping and stacking machine includes: a longitudinal walking mechanism, a loading, picking and flipping mechanism and a 180-degree vertical flipping mechanism.

[0023] The longitudinal walking mechanism includes: a longitudinal walking rail, a longitudinal driving hydraulic motor, a 90-degree flip sensor, a walking wheel bearing, a walking wheel and a front end anti-collision sensor;

[0024] The feeding, picking and flipping mechanism comprises: a swing arm oil cylinder, a swing arm, a balance body, an angle limit, an upper limit of the swing angle, a pickup upper sensor, an electromagnet, a flip driving motor, a feeding and picking crosshead and a 90-degree rotating sensing block; the swing arm oil cylinder is connected to the swing arm, one fulcrum of the swing arm is fixedly connected to the frame body through a fixed bearing, and the other fulcrum is connected to the feeding and picking crosshead through the flip driving motor;

[0025] The 180-degree vertical flip mechanism comprises: a 180-degree flip cylinder, a left 180-degree flip arm, a 180-degree flip electromagnet, a hydraulic station, a 180-degree left flip arm gear, a 180-degree right flip arm gear and a right 180-degree flip arm; the 180-degree flip cylinder is connected to the left 180-degree flip arm and the right 180-degree flip arm respectively, and the 180-degree flip electromagnet controls the flipping of the 180-degree left flip arm gear and the 180-degree right flip arm gear;

[0026] The longitudinal drive hydraulic motor guides the loading and picking crosshead to the top of the work station, the swing arm cylinder swings up, the flip drive motor sends a rotation signal, the loading and picking crosshead rotates, the loading and picking are flipped 90 degrees, the longitudinal drive hydraulic motor executes the backward spacing instruction, the swing arm cylinder swings up, and the 180-degree flip of the ball flat steel loading and picking is completed.

[0027] In another embodiment of the utility model, a 90-degree rotating sensing block is respectively arranged at the same position on the four branches of the loading and picking crosshead for sensing with the angle limit sensor.

[0028] In another embodiment of the utility model, the swing arm oil cylinder swings upward, the flip drive motor sends a rotation signal, the loading and picking crosshead rotates, and the loading and picking is flipped 90 degrees, including:

[0029] The electromagnet is energized, and the swing arm cylinder sends an upward swing signal. When the upper pickup sensor senses the swing arm, the swing arm cylinder stops swinging upward. The upper pickup sensor sends a rotation signal to the flip drive motor, and the loading and picking crosshead rotates. When the angle limit sensor senses the 90-degree rotation sensing block, the loading and picking crosshead stops rotating.

[0030] In another embodiment of the utility model, when the 90-degree flip sensor is used to sense the ball flat steel, it sends a 90-degree swing and upper magnetic signal to the 180-degree flip cylinder and the 180-degree flip electromagnet. After the 90-degree flip arm is closed, the left 180-degree flip arm sensor sends a return command to the 180-degree flip cylinder.

[0031] In another embodiment of the utility model, the installation positions of the 90-degree flip sensor, the front anti-collision sensor, the upper pickup sensor and the 90-degree rotation sensing block can be adjusted as needed.

[0032] In another embodiment of the utility model, an automatic bulb flat steel flipping and stacking machine, the longitudinal walking mechanism, the loading and picking flipping mechanism and the 180-degree vertical flipping mechanism produce orderly action steps through the upper and lower sensor devices during operation, so that the bulb flat steel stacking spacing is equal (the installation position of each sensor can be adjusted). The longitudinal walking mechanism is equipped with a walking distance encoder, which can make the crosshead picking mechanism accurately fall on the center point of the bulb flat steel width under the preset distance, thereby improving the accuracy of the stacking spacing.

[0033] Use a crane to lift the ball flat steel to the A and B workstations as shown in the figure, stack them neatly, remove the strapping tape, and then start the control system.

[0034] The spacing of C is preset, and the button of the longitudinal driving hydraulic motor 24 is turned on to guide the loading and picking crosshead 31 to the top of the A station and then stop.

[0035] After the C device sends a downward swing command to the swing arm cylinder 14, when the pressure sensor of the swing arm cylinder 14 reaches the preset value, it sends a pull-in signal to the electromagnet 22, and after the pull-in, the electromagnet 22 feeds back to the swing arm cylinder 14 to send an upward swing signal. When the upper pickup sensor 21 senses the swing arm 16, the upward swing stops, and the upper pickup sensor 21 sends a rotation signal to the flip drive motor 30, and the crosshead rotating device rotates. When the angle limit 19 sensor senses the 90-degree rotation of the sensing block 32, the crosshead stops rotating (there is a sensing block at the same position on each of the four branches of the crosshead), the first bulb flat steel is picked up and flipped 90 degrees, and the angle limit 19 sends a backward spacing command to the C encoder longitudinal drive hydraulic motor 24 walking mechanism.

[0036] After the swing arm cylinder 14 receives the instruction from the longitudinal drive hydraulic motor 24, the above steps are repeated once, and the first bulb flat steel is loaded, picked up and turned 180 degrees.

[0037] When the bulb flat steel reaches the upper limit position 20 of the swing angle, the transverse drive hydraulic motor 13 and the swing arm cylinder 14 are simultaneously given a signal to longitudinally transport and repeat the above steps. After repeating several times, the bulb flat steel turns to the 90-degree flip sensor 25 and waits for a signal.

[0038] When the 90-degree flip sensor 25 senses the bulb flat steel, it sends a 90-degree swing and magnetic-up signal to the 180-degree flip cylinder and the 180-degree flip electromagnet, and the previous actions are performed synchronously; after the 90-degree flip arm is closed, the left 180-degree flip arm sensor sends a return command to the 180-degree flip cylinder, and all previous actions stop.

[0039] After the sensor between the 180-degree turning cylinder and the left 180-degree turning arm sends a command to 10 to retract the stopper pin, the previous work is carried out synchronously. When a certain number of bulb flat steels are stacked in the waiting material area, a conveying command is sent to the conveying mechanism in the transverse conveying roller.

[0040] The technical solution of the utility model adopts mechanized operation to replace manual operation, which is more suitable for industrial production in terms of production technology. The automatic bulb flat steel turning machine is less restricted by climate and manual physical strength, which greatly improves production efficiency and reduces operation costs.

[0041] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
