[0024] See also Figure 1-Figure 5The present invention discloses a material paralleling and sorting machine for rectangular materials, comprising a steering sorting and sorting mechanism A, a pushing and sorting mechanism B, a multi-gripper assembly C, a first lane conveyor line 1, a second lane conveyor line 2, a third lane conveyor line 3, a fourth lane conveyor line 4, a first reasonable material processing line 5, a second reasonable material processing line 6, a third reasonable material processing line 7 and a fourth reasonable material processing line 8. The first reasonable material processing line 5 and the second reasonable material processing line 6 are arranged in parallel, wherein the rear end (input end) of the first reasonable material processing line 5 is longer than the second reasonable material processing line 6; the front ends (output ends) of the two are flush, respectively corresponding to the rear ends of the third reasonable material processing line 7 and the fourth reasonable material processing line 8 arranged in parallel. On one side of the input end of the first reasonable material processing line 5, a first lane conveyor line 1 and a second lane conveyor line 2 are arranged perpendicular to and in parallel therewith. On one side of the input end of the second reasonable material processing line 6, a third lane conveyor line 3 and a fourth lane conveyor line 4 are arranged perpendicular to and in parallel therewith. A turning and sorting material sorting mechanism A is provided above the output ends of the first and second lane conveyor lines 1 and 2 (the ends adjacent to the first processing line 5); another turning and sorting material sorting mechanism A is provided above the output ends of the third and fourth lane conveyor lines 3 and 4. A pushing and sorting mechanism B is provided between the output ends of the first processing line 5 and the second processing line 6 and the input ends of the third processing line 7 and the fourth processing line 8; a multi-gripper assembly C is provided above the third processing line 7 and the fourth processing line 8. A plurality of fans H are provided above the first processing line 5 and the second processing line 6 for cooling the material F.

[0025] The first lane conveyor line 1, the second lane conveyor line 2, the third lane conveyor line 3, the fourth lane conveyor line 4, the first processing line 5, the second processing line 6, the third processing line 7 and the fourth processing line 8 are used to convey the material F placed in the material box G. They are conventional conveyor belt transmission devices, all driven by servo motors and synchronous belt transmission mechanisms. The driving shafts (rollers) at the front ends of the first processing line 5 and the second processing line 6 are connected to the driving shaft B36 through the first synchronous belt 10, and the driving shafts (rollers) at the front ends of the third processing line 7 and the fourth processing line 8 are connected to the driving shaft B36 through the second synchronous belt 9. The power input pulley D is fixed on the output shaft of the servo motor (power device, not shown), and the power input pulley D is connected to the driving shaft B36 through the third synchronous belt 11. The first processing line 5, the second processing line 6 and the third processing line 7, the fourth processing line 8 have different reduction ratios, so as to achieve different running speeds.

[0026] A detection mechanism for controlling the material grabbing and feeding actions of the steering sorting and sorting mechanism A is installed beside the driving shaft B36. The detection mechanism includes a driving gear 12, a driven gear 13, a detection cam E and a detection proximity switch X. The driving gear 12 is installed on the driving shaft B36; the driven gear 13 and the detection cam E are coaxially installed beside the driving shaft B36 (see Figure 5 ), the detection proximity switch X is fixed to the top of the detection cam E through the bracket. The driving gear 12 and the driven gear 13 mesh with each other to realize the rotation of the drive shaft B36, and then the detection cam E rotates. Because there is a protrusion around the detection cam E, when the protrusion of the detection cam E turns to the bottom of the detection proximity switch X, the detection proximity switch X sends a corresponding signal, and the position at this time is also the starting position of the servo motor (with the power input pulley D installed). The detection proximity switch X has three functions: First, it resets the servo motor to the starting position, which is the position where the detection proximity switch X lights up. There is a long hole on the detection cam. By adjusting the position of the protrusion, the proximity switch X can be lit early or late. The basis for the adjustment is that the push plate B14 in the push material sorting mechanism B is located between the front and rear materials F when it falls, and the push plate B14 can push the material before the front limit; second, the position where the detection proximity switch X lights up is used as the starting point to set the steering sorting mechanism A (see Figure 6 ) of the material grabbing starting position and the material grabbing ending position, that is, the rice noodles will be grabbed only within this interval; the third is to determine the feeding position of the single gripper A2 of the steering sorting and sorting mechanism A (towards the first and second processing lines 5 and 6) (such as Figure 7 status shown).

[0027] The first conductive wire 5, the second conductive wire 6, the third conductive wire 7 and the fourth conductive wire 8 may be driven in other ways.

The gripper cylinder A21 (the prior art) is provided with two pneumatic fingers that can open and close 180 degrees. The pneumatic fingers drive the two relative grippers A25 to open and close.

[0032] The working process of the steering sorting and material sorting mechanism A is as follows:

[0033] 1) After the photoelectric sensor detects that the material F on the incoming material conveying line is in place, the gripper cylinder A21 drives the respective grippers A25 to respectively clamp the respective materials F in place;

[0034] 2) Lifting cylinder A3 lifts the material into place;

[0035] 3) Push the material F out of the material turning cylinder A11. Figure 6 Change to Figure 7 , which enables the material F to be turned 90° synchronously during the ejection process;

[0036] 4) When the feeding proximity switch detects a signal, the gripper cylinder A21 opens to feed the material;

[0037] 5) Pushing and steering cylinder A11 returns;

The bottom end of a swing rod B18 is radially connected to each end near the swing shaft B12. The top end of the swing rod B18 extends upward to the top of the first and second reasonable feeding lines 5 and 6. The top ends of the swing rods B18 are connected to each other by a tensioning brace B16. The rear end of the push rod B13 is rotatably connected between the top ends of the two swing rods B18 through a connecting shaft B19. The two ends of the push plate B14 are connected to the front ends of the two push rods B13. A guide bearing B15 is installed at one end of the push plate B14. A guide assembly B2 is installed on the frame below the outer side of a push rod B13.

[0041] See also Fig.10The guide assembly B2 includes: a guide plate body B21, a rear guide plate B22, an upper guide plate B23, a return spring B24, a front guide plate B25 and a support arm B26. The guide plate body B21 is horizontally fixed on the frame, and the rear guide plate B22 is fixedly installed on the upper rear part of the guide plate body B21; a support arm B26 is provided on the guide plate body B21 corresponding to the front of the rear guide plate B22, the rear end of the upper guide plate B23 is hinged to the top of the support arm B26, and the front guide plate B25 is fixed to the front end of the upper guide plate B23. The top ends of the front guide plate B25 and the rear guide plate B22 are both tilted backwards, and the upper surface of the upper guide plate B23 is parallel to the upper surface of the guide plate body B21; the rear guide plate B22, the upper guide plate B23 and the front guide plate B25 are on the same straight line (in the front-to-back direction). A return spring B24 is connected between the upper guide plate B23 and the guide plate body B21. The guide bearing B15 of the pusher assembly B1 corresponds to the upper surface of the upper guide plate B23. Fig. 9 The pusher sorting drive assembly B3 includes: a main shaft cam B31, a bearing B32, a driving swing arm B33, a swing arm spring B34, a connecting rod B35 and a driving shaft B36. The two ends of the driving shaft B36 are installed under the frame through the bearings of the bearing seat, and the main shaft cam B31 is fixed in the middle of the driving shaft B36. When working, the power device (such as a servo motor, not shown) is connected to one end of the driving shaft 36 through the power input pulley D and the synchronous belt 11 (see Figure 1 and Figure 4 ). A fulcrum shaft of an L-shaped driving swing arm B33 is rotatably mounted on the frame above the driving shaft 36; a bearing B32 is mounted at the lower end of the driving swing arm B33, the bearing B32 abuts against the circumference of the main shaft cam B31, and a swing arm spring B34 is connected between the upper end of the driving swing arm B33 and the frame. The upper end of the driving swing arm B33 is hinged to the front end of the connecting rod B35, and the rear end of the connecting rod B35 is hinged to the upper end of the driven swing arm B17 of the pusher assembly B1.

[0042] The working process of the pusher sorting mechanism B is as follows (see Figure 11-Figure 14 ):

[0043] The function of the pusher sorting mechanism B is to sort the materials that are not neat or slightly moved or not moved during feeding due to other reasons to the required distance. The specific actions are as follows:

[0044] 1) The power device (not shown) drives the drive shaft 36 and the main shaft cam B31 of the pusher sorting drive assembly B3 to rotate synchronously through the power input pulley D and the synchronous belt 11. The main shaft cam B31 drives the driving swing arm B33 to swing around its fulcrum axis through the bearing B32. The function of the swing arm spring B34 is to ensure that the bearing B32 moves along the trajectory of the outer periphery of the main shaft cam B31. The other end of the driving swing arm B33 drives the top of the swing arm B17 to move forward and backward through the connecting rod B35, and the swing arm B17 drives the swing arms B18 at both ends to swing forward and backward through the swing shaft B12.

[0045] 2) The push plate B14 is fixed on the push rod B13 which is hinged with the swing shaft B12, and the guide bearing B15 is fixed on the push rod B13. Since the guide bearing B15 is limited by the guide plate body B21, when the swing arm B18 swings forward, the push plate B14 moves forward horizontally along the upper surface of the guide plate body B21. The initial state is that the push plate B14 is at the rear limit position ( Fig.11 ), when the guide bearing B15 moves forward and passes under the upper guide plate B23 and meets the front guide plate B25, the front guide plate B25 and the upper guide plate B23 are pushed upward together (see Fig.12 ), when the guide bearing B15 completely passes through the front guide plate B25, the front guide plate B25 and the upper guide plate B23 are reset under the action of the reset spring B24 and fall onto the top of the guide plate body B21, while the push plate B14 continues to move forward to the front limit ( Fig.13 shown).

[0046] 3) The main shaft cam B31 continues to rotate, driving the push plate B14 to move backward. When the guide bearing B15 encounters the front guide plate B25, the guide bearing B15 moves backward along the front guide plate B25 and the upper guide plate B23 in turn, thereby pushing the push plate B14 upward (see Fig.14 ), so that the material can pass normally from under the push plate B14; when the push plate B14 continues to move backward until the guide bearing B15 is completely separated from the rear end of the upper guide plate B23, under the action of gravity, the push plate B14 falls onto the inclined surface of the rear guide plate B22, which plays a shock-absorbing role. As the main shaft cam B31 continues to rotate, the push plate B14 moves forward horizontally to Fig.10 The (rear limit) state shown starts the next cycle process.

[0047] 4) The push plate B14 moves back and forth in a cycle, and the material F is automatically pushed to the required position once, and the linked conveyor belts (the third reasonable material collection line 7 and the fourth reasonable material collection conveyor line 8) convey the material synchronously, and this cycle is repeated to achieve the purpose of material sorting.

[0048] See also Fig.15The multi-gripper assembly C is an existing technology, which is provided with a row of multiple grippers C1, each gripper C1 is driven by a cylinder. Its working principle is: when the material arrives at the position, each cylinder of the multi-gripper assembly C drives the corresponding gripper C1 to grab the material. When the multi-gripper assembly C moves to the top of the material box G under the drive of the mechanism, each cylinder of the gripper assembly opens to release the material.

[0049] The overall dynamic operation process of the present invention:

[0050] 1. Figure 1 The material F in the first conveyor line 1 and the second conveyor line 2 are transported to the vicinity of the first reasonable material processing line 5 (see Figure 1 ), then the first suitable material handling line 5 near the steering sorting mechanism A grabs and puts the material F according to the set rules, so that the material F conveyed on the conveyor line body 5 is transported at a distance of D1 and turns 90° (see Figure 2 ).

[0051] The first lane conveyor line 1 and the second lane conveyor line 2 are driven by separate motors. There is a material grabbing detection photoelectric switch Y1 at the front end of each of the first lane conveyor line 1 and the second lane conveyor line 2. A material incoming detection photoelectric switch Y2 is set at a position spaced one length of material F. The material grabbing detection photoelectric switch Y1 is used to detect whether the material F is in place, and the material incoming detection photoelectric switch Y2 is used to detect whether the next material F on each line has arrived. One photoelectric switch can also be used on each line, but the control accuracy is not as high as that of the above two photoelectric switches.

[0052] 2. Similarly, the material F is transported to the vicinity of the second reasonable feeding line 6 through the third branch conveyor line 3 and the fourth branch conveyor line 4. Then, the steering sorting and sorting mechanism A near the second reasonable feeding line 6 grabs and puts the material F according to the set rules, so that the distance between the materials F transported on the second reasonable feeding line 6 is D1 and corresponds to the position of the first reasonable feeding line 5 one by one (see Figure 2 and Figure 3 ), so as to achieve the purpose of material sorting.

[0053] 3. When the material F is transported from the first and second material processing lines 5 and 6 to the vicinity of the pusher sorting mechanism B, the pusher sorting mechanism B further sorts the material F, making the material F more orderly and its interval reduced to D2 (see Figure 4 ).

[0054] 4. The multi-gripper assembly C grabs the material F on the third and fourth material processing lines 7 and 8 in turn at the set grabbing position, and then puts them into the material box G in the aging box. The material box G is fixed on the chain conveyed inside the aging box. The power motor of the aging box will convey the material in the material box on the chain for aging according to the set action.

[0055] The fan H is turned on at the same time as the conveyor line is started. Its purpose is to cool down the rice noodles (material F) on the conveyor line to prevent the rice noodles from becoming sticky due to the high ambient temperature during transportation and sticking to the belt or grabbing fixture, resulting in inaccurate conveying position and reducing the difficulty of sorting the rice noodles.
