Description

Technical Field

[0002] After the product is produced, it is usually packaged to prevent it from being contaminated, and bag packaging is a commonly used packaging method.

[0003] But for soft and elastic products, such as Fig.24 The urine collecting bag 8 shown in the figure comprises a hard box body 81, a connecting hose 82 and a soft bag 83 located on the upper side of the box body 81 and connected to the box body 81; it needs to be folded and packed, that is, the two sides of the soft bag 83 are bent to the upper side, the connecting hose 82 is coiled and located on the upper side of the soft bag 83, and then the folded urine collecting bag is bagged; however, the soft bag 83 and the connecting hose 82 are both elastic and can be easily restored to the unfolded state. When packaging such products, it is necessary to keep the folded state of the products in real time and then put them into the bag (such as Fig.25 shown).

[0004] For the above-mentioned products that are difficult to maintain in a restrained state without external force, when bagging, they can generally only be kept in a restrained state by manual labor (reducing the volume, folding, etc.) before bagging; however, the manual method will consume a lot of energy of the operator to maintain the restrained state of the product, resulting in a relatively long bagging time and a very low bagging efficiency.

[0060] The working process of a close-fitting bagging device in this embodiment includes a loading process, a conveying process, a bagging process, and a bag supply process, which are specifically as follows:

[0061] Feeding process: The feeding mechanism 2 has three states, namely, manual feeding state, pre-pressing state, and discharging state; among them, (1) manual feeding state: Figure 4 and Fig.13 As shown, the pressing plate 22 is located above the feeding guide groove 21, and the movable bottom plate 23 is located in the feeding guide groove 21 to form the bearing surface of the feeding guide groove 21; this yielding driving mechanism 24 drives the pressing plate 22 to move forward by about half of the position as a whole, so as to give up about half of the discharge port of the feeding guide groove 21, and the operator constrains (folds or compresses) the article 8 to be bagged. For the urine collecting bag of this embodiment, the box body 81 needs to be facing downward, and the soft bag 83 is folded upward on the upper side of the box body, and the connecting hose 82 is coiled on the upper side of the folded soft bag 83. After the constraint is completed, the maximum width of the urine collecting bag is the box body. The width of the box body 81 is smaller at one end and larger at the other end. When constraining, the smaller end faces forward). Then, the items to be bagged are placed from the discharge port at the rear of the top side of the feeding guide groove 21, and the front end of the items to be bagged is inserted into the position between the rear half of the pressing plate 22 and the bearing surface, so that after the operator releases the pressing plate 22, the items to be bagged can still maintain the constrained state through the rear half of the pressing plate 22 and the bearing surface and the feeding guide groove 21. It should be noted here that the front and rear ends of the pressing plate 22 are provided with inclined guide surfaces to facilitate the insertion of the items to be bagged; (2) Pre-pressed state: such as Figure 5 , Figure 6 and Fig.14 As shown, the yield driving mechanism 24 drives the pressing plate 22 to move backward as a whole, so that the pressing plate 22 is located just above the upper opening of the feeding guide groove 21. At this time, the pressing plate 22 is completely pre-pressed on the items to be bagged; (3) Discharging state: as shown in FIG. Figure 7 and Fig.15 As shown, the bottom plate driving mechanism 25 drives the movable bottom plate to move toward the outside of the upper material guide groove 21, so that the lower opening of the upper material guide groove 21 is unobstructed. At this time, the pressing plate 22 is driven downward by the pressing mechanism 26, so that the items to be bagged can quickly enter the bearing area of ​​the conveying channel in a constrained state.

[0062] Conveying process: After the items to be bagged enter the carrying area, the bottom side of the items to be bagged is carried by the carrying plates 12 on the chain conveying mechanisms on both sides. The chain conveying mechanisms on both sides operate synchronously, and the driving chain drives the items to be bagged on the carrying plates 12 to move forward and enter the guide cover. Through the intermittent conveying of the chain conveying mechanism, the items to be bagged are conveyed to the top material mechanism. It should be noted here that the guide cover is also provided with an inclined guide surface at the rear edge of the second upper opening to facilitate the items to be bagged to enter the guide cover.

[0063] Bagging process: The bagging mechanism has four states, namely, the feeding preparation state, the feeding state, the pushing and bagging state, and the overall pushing state; among them, (1) the feeding state: Fig. 20 As shown, the front and rear ends of the bottom side of the self-weight pressing material moving frame 321 are provided with inclined guides. The partition plate on the front side of the bearing area of ​​the items to be bagged in the conveying channel will first contact the inclined guide of the self-weight pressing material moving frame 321. Under the action of the inclined guide and the forward movement of the partition plate, the partition plate 13 will partially lift the self-weight pressing material moving frame 321. When the partition plate 13 enters the bottom of the self-weight pressing material moving frame 321, the items to be bagged contact the self-weight pressing material moving frame 321 and further lift the self-weight pressing material moving frame 321. When the bearing area is located in correspondence with the first lower opening, the chain conveying mechanism stops moving. At this time, the items to be bagged carried by the bearing area are located directly above the lifting mechanism 34; (2) Lifting state: as shown in FIG. Fig.21 As shown, the lifting plate is arranged between the two side bearing plates, and the lifting driving mechanism drives the lifting plate to lift up from between the two side bearing plates. With the cooperation of the self-weight pressing material moving frame 321 providing the pressing force by its own weight, the articles to be bagged are pushed into the bagging guide groove 35 while maintaining the restraint state; (3) Pushing material bagging state: as shown in FIG. Fig. 22 As shown, at this time, the bag clamping mechanism at the front end of the bagging guide groove 35 has fixed the open bag 9, and the open bag 9 is opened by the lower support part 3101 and the upper support part 3102, and the two sides of the lower support part 3101 are also provided with restraining plates; the pushing drive mechanism 334 drives the pushing head 331 to move forward along the bagging guide groove 35. Under the restraint of the upper support part 3101 and the upper support part 3102 and the restraining plates on both sides of the lower support part, the items to be bagged are pushed into the bag 9; (4) Overall pushing state: as shown in FIG. Fig.23 As shown, the pushing drive mechanism 334 drives the pushing head 331 to continue to move forward, and the bagged articles continue to move forward, thereby driving the bag 9 to escape from the bag clamping mechanism, thereby completing the bagging process.

[0064] Bag supply process: The bag supply mechanism has four states, namely, bag taking state, bag opening state, bag putting state, and bag clamping state; among them, (1) bag taking state: the bag storage lifting drive mechanism 41 of the bag storage bin 4 drives the bag storage lifting plate to drive the bag 9 to rise in the bin frame body 42, so that the uppermost bag 9 is located at the bag taking station; the bag taking end 53 of the bag taking manipulator 5 moves to the left to the top of the bag taking station through the first horizontal drive mechanism 51, and the bag taking end 53 of the bag taking manipulator 5 is driven to descend through the vertical drive mechanism 52, and the four suction devices 7 of the bag taking end 53 correspond to the four corners of the bag 9 respectively, and the bag taking end 53 sucks the bag 9 through the suction device 7, and then the bag taking end 53 is driven to rise again by the vertical drive mechanism 52, and moves to the right to the right limit position through the first horizontal drive mechanism 51; (2) bag opening state: as Fig.16 and Fig.17As shown, the bag holding end of the bag opening manipulator 6 is driven forward to the bag opening of the bag 9 by the second transverse driving mechanism 61, and the upper and lower bag holding ends are driven by the double-head driving mechanism 62 to move synchronously toward each other, and each bag holding end is provided with two left and right suction devices. The bag opening manipulator 6 sucks the top side and the bottom side of the bag opening of the bag 9 through two groups of upper and lower suction devices, and each group of left and right suction devices. At the same time, the bag taking manipulator 5 moves back to the bag taking station; then, the bag holding ends of the bag opening manipulator 6 are driven by the double-head driving mechanism 62 to move synchronously away from each other, and the bag opening of the bag 9 is sucked up and down. , and is opened with the separation of the bag holding ends; in this state, the bag clamping driving mechanism 3111 of the bag clamping mechanism 31 drives the first clamping plate 3108 and drives the lower clamping part 3103 to move downward through the first bag clamping guide column 3105. At the same time, when the first clamping plate 3108 reaches the limiting step 3107, it drives the upper support part 3102 to move downward through the second bag clamping guide column 3106, so that the upper support part 3102 and the lower support part 3101 are closed, while the upper support part 3102 and the upper clamping part 3104 are separated, and the lower clamping part 3103 and the lower support part 3101 are separated; (3) Bagging state: as Fig.18 As shown, the bag holding end of the bag opening manipulator 6 is driven backward to the bag clamping mechanism 31 by the second transverse driving mechanism 61, and the bag 9 is quickly and smoothly sleeved on the outside of the lower support part 3101 and the upper support part 3102 through the narrowing guide of the front end of the lower support part 3101 and the upper support part 3102; (4) bag clamping state: the bag clamping driving mechanism 3111 drives the first clamping plate 3108 and drives the upper clamping part 3103 to move upward through the first bag clamping guide column 3105. At the same time, the first clamping plate 3108 drives the second clamping plate 3109 by the spring and drives the upper support part 3103 to move upward through the second bag clamping guide column 3106; so that the upper support part 3102 is separated from the lower support part 3101 to continue to open the bag mouth to form an opening corresponding to the article to be bagged, and the upper support part 3102 is closed with the upper clamping part 3104, and the lower clamping part 3103 is closed with the lower support part 3101, thereby completing the clamping of the bag mouth.

[0065] It should be noted that the internal structure diagrams involved in the drawings of the specification ( Figures 13 to 15 , Figure 20 to Figure 23 ) is a cross-sectional schematic diagram of the elevation (the elevation composed of the front, back, top and bottom) where the center line (front-to-back direction) of the bagging feed channel along the conveying direction is located.
