A number of blocking mechanisms 7. The tray system 2 is mounted on the circular rail 4, and the transmission mechanism 6 drives the tray system 2 to circulate along the circular rail 4, and the turning mechanism includes a lower turning mechanism 9 disposed at the front end of the body 3. And an upturning mechanism 8 disposed at a rear end of the fuselage, the lower turning mechanism 9 includes a lower flip shaft 91, a flip base 92 mounted on the lower flip shaft 91, and a plurality of flaps disposed on the circumference of the flip base 92 The upper flip mechanism 8 includes an upper flip shaft 81, a flip base 82 mounted on the upper tilt shaft 81, and a plurality of telescopic assemblies 84 disposed on the circumference of the flip base 82 on the tray system 2 A locating pin 122 is provided that can be inserted between two adjacent flap assemblies 94 on the circumference of the flip-down base 92 or between two adjacent telescoping assemblies 84 on the circumference of the flip-up base 82.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the flap assembly 94 on the flip base 92 and the flip base 92 are provided in pairs on the lower flip shaft 91 and are symmetrically disposed on the front end of the fuselage 3 respectively. On both sides of the endless track 4, the flip base 92 and the lower flip shaft 91 are fastened by a front expansion sleeve 93; the shutter assembly 94 includes a flap 95 mounted on the lower base 92 via a rotating shaft 96, mounted therein A flap elastic returning member between the base 92 and the blocking piece 95 is lowered, and a limiting screw 910 is mounted on the lowering base 92. The lowering base 92 is provided with a reset groove on one side of the blocking piece 95. The sheet 95 is provided with a reset rod 97 passing through the reset groove. On the opposite side of the flap 92, a spring fixing rod 99 is provided on the opposite side of the flap 95. The flap elastic returning member is connected to the reset rod 97 and the spring. A tension spring 98 is fixed between the rods 99. When the rotation speed of the lowering base 92 is greater than the rotation speed of the tray system 2 on the circular rail 4, the blocking piece 95 is rotated around the rotating shaft 96 under the toggle of the tray system positioning pin 122, and the tray system 2 and the blocking piece 95 do not interfere with each other, the tray After the system positioning pin 122 rotates through the blocking piece 95, the blocking piece elastic returning member pushes the blocking piece 95 to be reset; when the rotation speed of the lowering base 92 is less than or equal to the rotation speed of the tray system 2 on the circular track 4, the limiting screw 910 is pressed against the blocking piece. 95. The flap 95 is prevented from rotating around the rotating shaft 96 under the toggle of the tray system positioning pin 122, and the tray system 2 is turned down with the flap 95. When the transmission mechanism 6 transports the tray system 2 to the inversion area of the front end of the fuselage 3, under the joint action of the traction force and the gravity of the transmission mechanism 6, the tray system 2 is turned down, and the downwardly turning mechanism 9 of the constant speed continuously rotates at this time. The flap 95 catches the entire tray system 2 through the locating pins 122 on the tray system 2 and flips it down uniformly at a constant speed. A key feature of the present flip mechanism 9 is that the flap 95 is allowed to overspeed and the tray system 2 is prohibited from overspeeding. When the speed of the tray system 2 is less than the speed of the flap 95, the respective speeds of the tray system 2 and the flap 95 do not interfere with each other; when the speed of the tray system 2 exceeds the speed of the flap 95, the flap passes through the tray system 2 The locating pin 122 limits the speed of the tray system 2 so that it maintains a constant speed and steadily reverses downward. The above-described downward turning mechanism 9 uses a rotatable shutter 95 for the purpose of avoiding jamming when the end of the flap 95 just hits the positioning pin 122. The rotation of the flap 95 allows the position of the flap 95 and the positioning pin 122 to be jammed and damaged, thereby realizing the function of smoothly turning the tray system 2. At the same time, the rotational seating capability of the flap 95 provides the function of allowing the flap 95 to overspeed, so that when the tray system 2 is stopped at any position in the flipping area due to an external force, the rotation of the flip mechanism 9 is not affected, thereby protecting The device is protected from accidental damage.

Referring to FIG. 1 and FIG. 4, the telescopic assembly 84 on the upturned base 82 and the upturned base 82 are provided on the upper flip shaft 81, and are respectively symmetrically disposed on the rear end annular rail 4 of the fuselage 3.

The telescopic assembly 84 includes a sliding seat 85 disposed on the upturned base 82 and having a guide groove therein, and an outwardly extending guide groove of the body 3 and a tray on the rear end of the body 3 A lever 86 of the system 2 and a compression spring 88 mounted within the channel and capable of pushing the lever 86 outwardly. A second layer groove is disposed along the guiding groove, and the lever 86 is provided at one end of the guiding groove with a limiting pin 87 extending into the second layer groove, and the second layer groove of the sliding seat 85 The extension and retraction stroke of the lever 86 is limited by the limit pin 87. When the transmission mechanism 6 delivers the tray system 2 to the reversal area of the rear end of the fuselage 3, the lever 86 of the continuously rotating upturning system 8 flips the tray system 2 up by dialing the positioning pin 122; when the tray system 2 enters the flipping area During the process, if the end of the lever 86 just hits the positioning pin 122 of the tray system, the lever 86 will be retracted by the reverse thrust of the positioning pin 122 and the compression spring will be compressed 88, with the upward turning mechanism 8 Continuing to rotate, the lever 86 is retracted and then passes over the positioning pin 122. The thrust of the compression spring 88 causes the lever 86 to extend and reset, and the tray system 2 here can be turned up by the next telescopic assembly. The above-described upward turning mechanism 8 uses the telescopic assembly 84 in order to prevent the end of the lever 86 from being caught when it just hits the positioning pin 122. Through the expansion and contraction of the lever 86, the lever 86 and the positioning pin 122 are prevented from being jammed and damaged, thereby realizing the function of smoothly turning the tray system 2.

Referring to Figures 8, 9, and 10, the transmission mechanism 6 includes a sprocket mounted on the lower flip shaft 91 and the upper flip shaft 81, a drive chain mounted on the sprocket, and driving the lower flip The motor 102 of the shaft 91, the tray system 2 includes a tray mechanism 12 and a traction mechanism 11 mounted on the tray mechanism 12, the traction mechanism 11 including a traction sprocket 118 engaged with the transmission chain and the traction A damper device to which the sprocket 118 is connected.

The rocker arm 113 is mounted on the traction base 111 via the rocker shaft 112. The elastic reset member can be The rocker arm 113 is distracted toward one side of the transmission chain, the damping device is a permanent magnet damper 117, and the traction sprocket 118 is mounted on a permanent magnet damper 117, the permanent magnet damper 117 Mounted on the rocker arm 113, the traction base 111 is provided with a mounting hole, and the elastic returning member is a return spring 115 mounted in the mounting hole, and the pulling base 111 is mounted on the mounting hole The opposite side is provided with a card slot, and the rocker arm 113 is provided with a limiting block 114 extending into the card slot. The end of the returning spring 115 is fitted with a slider against the limiting block 114 at the end of the mounting hole 115. 116. The rocker arm 113 is rotatable about the rocker shaft 112 on the traction base 111, the slider 116 is slidable in the mounting hole of the traction base 111, and the compressed return spring 115 pushes the slider 116 outward through the extrusion limit. The block 114 presses the rocker arm 113 against the card slot of the traction base 111 to achieve flexible positioning of the traction sprocket 118 in the height direction. When the tray system 2 passes through the circular arc-shaped reversing track at both ends of the fuselage 3, the distance between the traction mechanism 11 and the transmission chain changes, and at this time, the transmission chain presses the traction sprocket 118 to rotate the rocker arm 113 about the rocker shaft 112. A certain angle, thereby eliminating the interference caused by the change of the distance between the transmission mechanism and the transmission chain. The above-mentioned transmission mechanism has the advantage that by using the permanent magnet damper 117, since the torque of the permanent magnet damper 117 is very stable and almost wear-free, it is ensured that the traction force is constant and reliable at any speed and load. This avoids the problem that the friction damper is unstable in torque and wears out and needs to be replaced periodically.

Referring to FIG. 11 and FIG. 12, the device anti-overload mechanism 10 further includes a torsion arm 103, a spring seat 104, a spring guide 105, an overload prevention spring 106 and a sensor 108, and the motor 102 is mounted under The power is outputted on the inverting shaft 91, and the torsion arm 103 is mounted on the motor 102. The spring seat 104 is mounted on one side of the body 3 facing the torsion arm 103, and the spring guide 105 is mounted on the spring seat 104, the torsion The arm 103 is fitted on the spring guide 105, and the anti-overload spring 106 is fitted on a spring guide 105 between the spring seat 104 and the torsion arm 103. The sensor 108 monitors the swing angle of the torque arm 103 with the motor 102 in real time. The spring seat 104 is provided with a sensor bracket 107 extending to the opposite side of the torsion arm 103. The sensor bracket 107 is provided with a waist hole, and the sensor 108 is mounted on the waist hole of the sensor bracket 107. The torque arm 103 is provided with a sensing block 109 corresponding to the sensor 108. The output torque of the motor 102 is reversely applied to the anti-overload spring 106 by the torsion arm 103 to compress the anti-overload spring 106, and the initial compression amount of the anti-overload spring 106 is adjusted by the spring guide 105 to control the output torque of the motor 102 when the motor 102 is controlled. When the overload reaches a certain value, the reaction torque of the motor 102 further compresses the anti-overload spring 106 through the torsion arm 103, and the motor 102, the torsion arm 103, and the sensing block 109 rotate together around the lower flip shaft 91 when rotating. When a certain amplitude is reached, the sensing block 109 leaves the sensing area of the sensor 108, causing the sensor 108 to not sense the signal, thereby causing the control program to initiate an emergency stop to prevent the motor 102 from being overloaded. The amount of oscillation of the motor 102 can be controlled by adjusting the mounting position of the sensor 108 in the waist hole of the sensor holder 107, thereby controlling the amount of overload.

The above-mentioned anti-overload mechanism of the device has the advantages that the emergency stop measure can be started immediately when the motor is overloaded, the mechanical and electrical components are prevented from being damaged, and the buffer function is activated at the time of startup or sudden change of the load, thereby prolonging the service life of the machine. The output torque of the motor can be controlled by adjusting the initial compression amount of the anti-overload spring to adapt to different usage requirements; the allowable swing amount of the motor can be controlled by adjusting the installation position of the sensor, thereby controlling the allowable overload amount.
