[0024] The empty container stacking bin 7 is suspended above the turntable 4. When the turntable 4 is stationary, the empty container stacking bin 7 faces the bayonet on the turntable 4, and the empty container stacking bin 7 can automatically and regularly deliver the empty container 8; the material conveying pipe 9 is arranged on the upper part of the container 8 and can be automatically opened and closed at a fixed time.

[0025] The conveyor belt 13 is driven by a pulley 17 to run continuously, and the continuous operation of the conveyor belt 13 can carry away the container 8 filled with the material 10 in time.

[0026] A filling method for an automatic double filling and conveying device comprises the following steps: Step 1: At the moment when the driving gear 1 and the driven gear 12 are about to engage, the bayonet A and the bayonet B receive the empty container 8; Step 2: When the driving gear 1 and the driven gear 12 are meshed, the container 8 filled with materials moves toward the entrance of the conveyor belt 13, and is transported away by the conveyor belt 13 when it reaches the entrance; during this process, the bayonet A and the bayonet B carry the empty container 8 to move below the material conveying pipe 9; Step 3: At the moment when the driving gear 1 and the driven gear 12 are meshed, the driving gear 1 continues to rotate, while the driven gear 12 is stationary, the valve of the material conveying pipe 9 is opened, and filling begins; Step 4: During the idling time of the driving gear 1, that is, during the period when the driven gear 12 is stationary, the filling process starts and ends, and then the next round of filling is started; at the moment when the container 8 is full, the valve of the material conveying pipe 9 is closed, and the toothed part of the driving gear 1 just rotates to the moment when it is about to mesh with the driven gear 12, and the next round of filling and transportation begins.

[0027] Assume that the driven gear 12 has z 2 teeth, z 2 is a multiple of 6, the module and pressure angle of the driving and driven gears are equal, and the standard installation; the driving gear 1 has z 1 teeth, actually z 2 / 3 teeth, no z 1 = z 2 / 3, that is, the driving gear 1 is only There are gear teeth in the range (including , is the gear ratio, also known as the transmission ratio or speed ratio), and the rest z 1 - z 2 / 3 teeth do not exist, and the position without gear teeth is the root circle of the driving gear 1; this makes it possible for the driven gear 12 to rotate only once every time the driving gear 1 rotates one circle. z 2 / 3 teeth stop, that is, for every rotation of the driving gear 1, the driven gear 12 rotates 1 / 3 of a circle, that is, for every rotation of the driving gear 1, the turntable 4 rotates 1 / 3 of a circle, thereby transmitting two containers 8 at a time; the rotation of the driven gear 12 is driven by the meshing of the driving and driven gears. z 2 / 3 teeth, the driving gear 1 also rotates z 2 / 3 teeth, due to the driving gear 1 the rest z 1 - z 2 / 3 teeth do not exist, so the driving gear 1 has The ring has no gear teeth (driven gear z 2 The root circle of each tooth is complete, and the root circle of the driving gear is The circle is the root circle of the gear, or the original z1 - z 2 / 3 tooth part is its root circle, so that when the toothed part of the driving gear 1 is completely out of mesh with the driven gear 12, the driving gear 1 continues to rotate, but the driving gear 1 and the driven gear 12 are not in contact, so that when the driving gear 1 rotates During the rotation, the driven gear 12 remains stationary; at the moment when the main and driven gears are out of mesh, the valve of the material conveying pipe 9 is opened to fill the material; when the driving gear 1 rotates past the toothless Within the circle time, the filling is just completed, and then the toothed part of the driving gear 1 begins to mesh with the driven gear 12; since the number of teeth of the driving gear 1 is z 2 / 3, so during the meshing process, the driven gear only rotates z 2 / 3 teeth, that is, the driven gear 12 only rotates 1 / 3 of a circle and then disengages, the driving gear 1 continues to rotate, while the driven gear 12 is stationary, that is, the turntable 4 is stationary, and the valve of the material conveying pipe 9 is immediately opened for filling.

[0028] In order to fill the container just when the driven gear 12 is stationary, the flow rate of the material conveying pipe 9 is q The solution is as follows. Assume the speed of driving gear 1 is RPM, the speed of driven gear 12 is RPM, the driving gear rotates Time required for a circle Minutes. Assume the volume of vessel 8 is Liters, the flow rate of the material conveying pipe 9 is Liter / minute. When the module and number of teeth of the driving gear 1 and the driven gear 12 are the same, , driving gear 1 only Within the circumference, that is, there are gears only within 120°, and the rest Circle, that is, the root circle of the gear without gear teeth within 240°. In this case, , the flow rate of the material conveying pipe 9 is Liter / minute; if , then the toothed portion of the driving gear 1 accounts for circle, and the remaining 1 / 3 circle is its tooth root circle. At this time, the flow rate of the material conveying pipe 9 is Liter / minute; if , then the toothed portion of the driving gear 1 accounts for The remaining 5 / 6 of the circle is the tooth root circle. At this time, the flow rate of the material conveying pipe 9 is Liters / minute...; adjust the speed ratio The flow rate and thus the filling speed can be varied.

[0029] After the motor 15 is decelerated by the reducer 16, it drives the driving gear 1 to rotate continuously.

Figure 1 Or the bayonet A (bayonet for taking and delivering containers containing materials) and bayonet B shown in 4 have each received an empty container 8. As the master and driven gears enter into meshing (such as Fig.10 ), Figure 1 Or the container 8 filled with the material 10 at the bayonet C and D shown in 4 moves toward the entrance of the conveyor belt 13; Figure 1 Or the bayonet A and B shown in 4 each carry an empty container 8 just received and move to the bayonet C and D, that is, under the material conveying pipe 9, respectively, to prepare for filling with material 10; Figure 1 Or the bayonet E and F shown in 4 move toward the bayonet A and B respectively, ready to receive the empty container 8; Figure 1 The container 8 of the bayonet D shown in FIG. 4 reaches the entrance of the conveyor belt 13 and is taken away by the conveyor belt 13; Figure 1 Or the container 8 of the bayonet C shown in FIG4 also reaches the entrance of the conveyor belt 13 and is immediately taken away by the conveyor belt 13, and the meshing ends at the same time. At this time, the meshing ends at the moment (see FIG4 ). Fig.11 ), Figure 1 Or the empty container 8 at the bayonet A and B shown in FIG4 just reaches the position C and D respectively, that is, reaches the bottom of the material conveying pipe 9, and then the valve of the material conveying pipe 9 opens to start filling the container 8 with the material 10. Figure 1 Or the bayonet C and D shown in 4 reach bayonet E and F respectively, Figure 1 Or the bayonet E and F shown in 4 reach the bayonet A and B respectively, and each receives an empty container 8 at the same time. Fig.12 ), the driving gear 1 continues to rotate, and since the driving and driven gears are not meshing at this time, the driven gear 12 is stationary and filling is in progress. The duration of idling of the driving gear 1 is Minutes, at this time the long inner container is just full; at the moment of fullness, the valve of the material conveying pipe 9 is immediately closed, and the driving gear 1 rotates to Fig. 9 The next round of filling is about to begin. ..., and the cycle repeats itself.
