[0039] Working process: manually put the empty bag into the empty bag bin, and the positioning hole on the empty bag is inserted into the empty bag positioning shaft 223 of the empty bag bin. After the empty bags are filled, confirm on the touch screen. When the empty bag bin alarms for empty bag shortage, the empty bag plate 25 drops to the lowest point and resets the button to perform bag replenishment. In order to adapt to empty bags of different specifications, the empty bag positioning shaft 223 can be adjusted forward and backward, so when using empty bags of different specifications, the centerline position of the empty bag remains unchanged.

[0040] After the bag is replenished, the empty bag plate 25 is lifted upward until the photoelectric switch 222 senses an empty bag, at which time the lifting stops. Before the lifting starts, the lifting blocks 267 of the lifting lock 1 263 and the lifting lock 264 are respectively inserted into the two lifting grids 2614 on the sliding lifting plate 265 to prevent the sliding lifting plate 265 from descending. When the lifting starts, the lifting cylinder 261 drives the lifting lock 1 263 to move upward, and the lifting block 267 drives the sliding lifting plate 265 to move upward. When the sliding lifting plate moves upward, the inclined surface milled on the lower edge of the lifting grid 2614 cooperates with the inclined surface of the lifting block 267 of the lifting lock 264, pressing the lifting block 267 inward, so that the lifting block 267 is separated from the current lifting grid 2614. When the lifting cylinder 261 moves to the right position, the lock block of the lifting lock head 264 can just pop out and push into the next lifting grid 2614, and fix the sliding lifting plate 265 again. When the lifting action of the lifting cylinder 261 is in place, it will start to retract after a short delay. During the retraction process, the lifting block 267 of the lifting lock block 1 will also be pressed back by the inclined surface of the lifting grid 2614 and detach from the current lifting grid 2614. After the lifting cylinder 261 is retracted to the right position, the lifting block 267 can also just pop out and push into the next lifting grid 2614. At this time, the device returns to the state before the lifting starts, completing an action cycle.

[0041] When the empty bags on the empty bag flat plate 25 consume a certain height, the device will be lifted once. After multiple cycles of lifting, the empty bag flat plate 25 is lifted to the highest point, and the empty bags need to be replenished.

[0042] When sucking empty bags, the empty bag suction cylinder 33 of the empty bag transfer part 3 moves downward, and the empty bag suction cup 36 sucks the empty bag. The empty bag suction cylinder 33 moves upward, and the empty bag transfer cylinder 31 is activated to move the empty bag to the top of the bagging and sealing platform 51. At the same time, the finished product already loaded on the bagging and sealing platform 51 is pushed to the discharge chute through the push plate 37. After the empty bag transfer cylinder 31 is in place, the empty bag suction cylinder 33 moves downward to place the empty bag on the bagging and sealing platform 51, and the push cylinder 34 moves upward to lift the push plate 37. The empty bag flat plate 25 is lifted up to a height of 15mm each time. The empty bag suction cup 36 is a special suction cup with a buffer rod, and the buffer stroke is 20mm. In combination with the stroke of the empty bag suction cylinder 33, the empty bag can be taken within a range of 15mm. The coordination of the lifting of the empty bag bin and the buffering of the suction cup can increase the cache height of the empty bags to 150mm, effectively reducing the number of times the empty bags are replenished and improving production efficiency. After the empty bags are placed on the bagging and sealing platform 51, the lower suction cup 58 for bag opening sucks the bottom of the empty bags, and the front and rear cylinders 53 for bag opening retract, driving the bag opening cylinder frame 54 to move to the working position. After reaching the working position, the bag opening cylinder 551 extends out, and the upper suction cup 57 for bag opening contacts and sucks the top of the empty bags. After sucking, the bag opening cylinder 551 retracts and opens the bag mouth. Before the empty bag transferring cylinder 31 completes its action, the front and rear cylinders 53 for bag opening are always in an extended state, and the bag opening cylinder frame 54 is located at Figure 7 The avoidance position shown is to prevent collision. After the empty bag is opened, the slide cylinder 52 pushes the bagging and sealing platform 51 to the frontmost bagging position, and the empty bag is inserted into the bag-stretching plate 64. After the bagging and sealing platform 51 is in place, the date printing cylinder 35 extends to drive the print head 38 to stamp the date on the bag. After the printing is completed, the date printing cylinder 35 retracts; the empty bag transfer cylinder 31 is activated, and the empty bag transfer part returns to the initial position. After the bagging and sealing platform 51 is in place, the bag-stretching and lifting cylinder 61 extends, and the bag-stretching beam 62 descends. After the bag-stretching beam 62 is in place, the left and right bag-stretching cylinders 631 retract at the same time, and the bag-stretching plate 64 stretches the bag opening to the required width for bagging. After the bag-holding action is completed, the push cylinder 2 45 moves to push the spoon / fork into the empty bag; before the bagging and sealing platform 51 reaches the bagging position, the bag-holding lifting cylinder 61 is in a retracted state, and the bag-holding plate 64 is a certain height away from the bagging and sealing surface to facilitate the empty bag to be inserted into the bag-holding plate 64. Before the push cylinder is bagged, the rotary silo needs to perform a certain action process, which will be reflected in the following text. To adapt to bags of different sizes, the position of the bag-holding cylinder 1 631 can be adjusted on the bag-holding beam. After bagging is completed, the push cylinder 2 45 retracts, and the bagging and sealing platform reaches the sealing position. After reaching the sealing position, the two bag-holding cylinders 2 632 on both sides act at the same time to flatten the bag mouth. After flattening, the sealing cylinder 561 extends out, and the sealing machine 562 is powered on to heat-seal the bag mouth. After sealing is completed, the sealing cylinder 561 retracts, the bag lifting cylinder 61 retracts, the slide cylinder 52 retracts, the bagging and sealing platform 51 returns to the initial position, the bag opening front and rear cylinders 53 extend out, and the bag opening cylinder frame 54 reaches the avoidance position, completing a bagging cycle.

[0043] Working process of the fork and spoon bin: In the initial state, the bin 44 is in a vertical state and is in the loading position. The top cover cylinder 446 retracts, the bin top cover plate 444 retracts, and the front baffle cylinder 447 extends. The bin front baffle 445 seals the front mouth of the bin 44, waiting for the robot to load. The robot puts the fork / spoon into the bin twice. After the photoelectric switch 448 senses that the discharge is completed, the top cover cylinder 446 extends, and the top cover cylinder 446 retracts to seal the upper mouth of the bin to prevent the spoon / fork from tipping over during the rotation. The rotating cylinder 42 drives the bin to rotate 90 degrees and reaches the loading position. At this time, the side push slide seat 71 extends, the side push slide 73 reaches the front position, and the side push plate 76 reaches the position that fits the upper cover plate to prevent the spoon / fork from tipping over when the bin top cover plate 444 is retracted. The top cover cylinder 446 retracts, and the side push cylinder 75 extends to squeeze the spoon / fork to a height suitable for bagging. At this time, the front stop cylinder 447 is retracted, the front opening of the silo is opened, and bagging can be carried out after the bag support is completed.

[0044] The technical solution of the present invention has the following advantages: the bag opening cylinder frame 54 can move forward and backward, and can move the sealing platform at multiple positions in the empty bag transfer part 3, saving costs; adding the sealing position of the bag filling and sealing platform to replace the movement of the bag support device 6 reduces the complexity of the system and improves work efficiency; the empty bag flat plate 25 can automatically lift upward, and can cache a large number of empty bags, thereby reducing the number of times the machine is stopped to replenish empty bags and improving production efficiency; the lifting device 26 uses a lifting cylinder 261, a push-pull cylinder 262, a lifting lock head 263 and a lifting lock head 264. The combination replaces the combination of servo motor and screw or synchronous belt and other driving methods, significantly reduces the manufacturing cost of the equipment, and reduces the debugging work of the jacking part; the fork and spoon bin part 4 can rotate, which is convenient for bagging and also convenient for putting forks or spoons into the bin 44 in multiple times, and the side push mechanism 7 can compress the height of the fork or spoon to be bagged, reducing the failure rate of the bagging process; the bin top cover plate 444 controlled by the top cover cylinder 446 and the bin front baffle plate 445 controlled by the front baffle cylinder 447 can prevent the fork or spoon inside from tipping over during the rotation of the fork and spoon bin.
