Description

Technical Field

[0001] The present invention relates to the technical field of packaging devices, and in particular to a garbage bag set, an automatic garbage packaging device and a method. Background Art

[0002] At present, the garbage bags on the market are divided into the following styles: flat-mouth garbage bags, vest-type garbage bags, and drawstring automatic closing garbage bags. These types of garbage bags can achieve the effect of collecting garbage. Among them, drawstring garbage bags are more popular because of their convenience, simplicity, and quick packaging. At present, the drawstring garbage bags on the market are closed roll garbage bags, and they are all put on the garbage can when in use. After use, they are picked up and the ropes are drawn, and then thrown away. Under special working conditions, it is impossible to quickly put the garbage bags into demand, and the garbage bags need to be opened and used again. The steps are relatively cumbersome and time-consuming. The way that sanitation equipment for garbage disposal handles garbage is mainly to transport the garbage to the designated garbage disposal point for disposal, and small unmanned sanitation equipment can automatically dump garbage at the garbage can location. Whether large-scale sanitation equipment or small-scale sanitation equipment handles garbage in the vehicle, it needs to go back and forth to the designated location to handle garbage and garbage bags based on manual or semi-automatic processing. The process mainly involves the expansion of garbage bags and the packaging of garbage bags, the replacement of garbage bags and repeated steps. The overall process is troublesome and time-consuming, and the sealing and safety of the packed garbage bags need to be further improved.

[0003] The prior art generally uses garbage bags and self-contained garbage boxes, and completes the laying of garbage bags and automatic replacement of garbage bags by suctioning air inside the fan; the packaging and packaging of garbage bags are generally achieved by an automatic heat sealing mechanism; there is also a prior art that controls the synchronous rotation of the rotating rod of the barrel mouth by a synchronous belt to complete the folding action of the garbage bag, and completes the preliminary packaging of the garbage bag by rotating the bottom disc, and finally uses a push rod and a tie to automatically seal the garbage bag. The prior art rarely involves the disclosure of an integrated automatic device for automatic replacement of garbage bags, laying of garbage bags, and packaging of garbage bags, and there is no disclosure of an automatic replacement and packaging device for drawstring-type garbage bags that combines the traditional advantages.

[0043] The present invention also provides a method for automatically packing garbage, using a garbage bag set and an automatic garbage packing device, comprising the following steps:

[0044] Step S1: Install the garbage bag set and adjust the position of the current garbage bag to the initial position;

[0045] Step S2: starting the second motor to make the first synchronous belt and the second synchronous belt rotate forward, driving the two finger cylinder groups to rise to the top position and align with the lower folded edge of the current garbage bag;

[0046] Step S3: the first finger cylinder and the second finger cylinder perform a closing action to clamp the lower folded edge of the current garbage bag;

[0047] Step S4: starting the second motor to reverse the first synchronous belt and the second synchronous belt, driving the two finger cylinder groups to descend to the bottom position, and the current garbage bag is pulled down to the preset position;

[0048] Step S5: the push rods of the first double-axis cylinder, the second double-axis cylinder, the third double-axis cylinder and the fourth double-axis cylinder are extended to press the current garbage bag onto the front support frame;

[0049] Step S6: starting the first motor to reverse the garbage bag reel, breaking the breakpoint connection between the current garbage bag and the next garbage bag, so that the current garbage bag is separated from the garbage bag group;

[0050] Step S7: The flip push rod is extended to flip the housing and the internal components from a vertical state to a horizontal state, so that the opening of the current garbage bag faces upward;

[0051] Step S8: Pour the garbage into the current garbage bag, and the compressed bag body of the current garbage bag naturally droops and unfolds under the gravity of the garbage;

[0052] Step S9: the first finger cylinder and the second finger cylinder perform an opening action, the push rods of the first double-axis cylinder and the third double-axis cylinder are retracted, and the push rods of the second double-axis cylinder and the fourth double-axis cylinder remain extended, so that the folding piece of the current garbage bag is loosened while the drawstring is still compressed, and the drawstring is naturally tightened under the gravity of the garbage, and the opening of the current garbage bag is closed;

[0053] Step S10: The push rods of the second double-axis cylinder and the fourth double-axis cylinder are retracted, the drawstring is loosened, and the current garbage bag with the opening tightened falls under the action of gravity and waits to be collected;

[0054] Step S11: flip the push rod and retract it, restore the shell and internal components from a horizontal state to a vertical state, and then jump back to step S2 if the garbage bag is not used up, and jump back to step S1 if the garbage bag is used up, and then re-execute the above process in sequence.

[0055] Preferably, in step S1, the garbage bag group is wound and installed on a garbage bag reel, and the first garbage bag on the outermost layer of the garbage bag group is the current garbage bag;

[0056] The initial position of the current garbage bag is located above the packaging mechanism and passes through the gap between the front drum and the rear drum. The lower folded edge of the current garbage bag is located between the front support frame and the rear support frame and is aligned with the upper beam of the front support frame.

[0057] Preferably, in step S2, the second motor is started to rotate forward, which drives the first synchronous wheel to rotate forward, and then drives the first synchronous belt to rotate forward, the forward rotation of the first synchronous belt drives the third synchronous wheel to rotate forward, the forward rotation of the third synchronous wheel drives the synchronous shaft to rotate forward, the forward rotation of the synchronous shaft drives the fourth synchronous wheel to rotate forward, the forward rotation of the fourth synchronous wheel drives the second synchronous belt to rotate forward, and finally the first synchronous belt and the second synchronous belt rotate forward synchronously;

[0058] The positive rotation of the first synchronous belt drives the first finger cylinder to move upward, and the positive rotation of the second synchronous belt drives the second finger cylinder to move upward. The first finger cylinder and the second finger cylinder have the same height and move synchronously.

[0059] The first finger cylinder and the second finger cylinder are initially in an open state. When the first finger cylinder and the second finger cylinder rise to the top position of the corresponding synchronous belt, the lower folded edge of the current garbage bag just extends into the opening of the first finger cylinder and the second finger cylinder, and the lower folded edge is aligned with the clamping part of the first finger cylinder and the second finger cylinder.

[0060] Preferably, in step S, the second motor is started to reverse, which drives the first synchronous wheel to reverse, and then drives the first synchronous belt to reverse, the reversal of the first synchronous belt drives the third synchronous wheel to reverse, the reversal of the third synchronous wheel drives the reversal of the synchronous shaft, the reversal of the synchronous shaft drives the fourth synchronous wheel to reverse, the reversal of the fourth synchronous wheel drives the second synchronous belt to reverse, and finally the first synchronous belt and the second synchronous belt are synchronously reversed;

[0061] The reversal of the first synchronous belt drives the first finger cylinder to move downward, and the reversal of the second synchronous belt drives the second finger cylinder to move downward. The first finger cylinder and the second finger cylinder have the same height and move synchronously.

[0062] During this process, the first finger cylinder and the second finger cylinder remain in a closed state and clamp the lower folded edge of the current garbage bag, thereby pulling the current garbage bag downward. When the first finger cylinder and the second finger cylinder descend to the bottom end position of the corresponding synchronous belt, the current garbage bag is just pulled down to the preset position;

[0063] The preset position of the current garbage bag is located in the middle of the rear support frame and the front support frame. In the preset position, the upper folded edge of the current garbage bag is clamped in the middle of the upper beam of the front support frame and the upper beam of the rear support frame, the upper folded edge opening of the current garbage bag and the exposed drawstring are facing the second double-axis cylinder on the upper beam of the rear support frame, and the lower folded edge of the current garbage bag is clamped in the middle of the lower beam of the front support frame and the lower beam of the rear support frame, and the lower folded edge opening of the current garbage bag and the exposed drawstring are facing the fourth double-axis cylinder on the lower beam of the rear support frame.

[0064] Preferably, in step S5,

[0065] The push rods of the first double-axis cylinder and the third double-axis cylinder extend to press the upper folded edge of the current garbage bag against the left and right sides of the upper beam of the front support frame respectively;

[0066] The push rod of the second double-axis cylinder extends to press the drawstring exposed at the upper folding edge opening of the current garbage bag against the center of the upper beam of the front support frame;

[0067] The push rod of the fourth double-axis cylinder extends out to press the drawstring exposed at the lower folding edge opening of the current garbage bag against the center of the lower beam of the front support frame.

[0068] Preferably, in step S6, the first finger cylinder and the second finger cylinder remain in a closed state, and the first double-axis cylinder, the second double-axis cylinder, the third double-axis cylinder and the fourth double-axis cylinder remain in an extended state, pressing the current garbage bag tightly on the front support frame and keeping it immobile;

[0069] Then, the first motor is started to reverse and drive the first gear to reverse, the reverse rotation of the first gear drives the second gear to reverse, and the reverse rotation of the second gear drives the garbage bag reel to reverse;

[0070] The upper folded edge of the current garbage bag is connected to the lower folded edge of the next garbage bag through a breakpoint. When the garbage bag reel is reversed, the next garbage bag is pulled back upward, and the breakpoint between the two garbage bags is broken after being stressed, thereby disconnecting the current garbage bag from the next garbage bag, and the current garbage bag is separated from the garbage bag group.

[0071] Preferably, in step S9, the first double-axis cylinder and the second double-axis cylinder perform an opening action to loosen the lower folded edge of the current garbage bag; the push rods of the first double-axis cylinder and the third double-axis cylinder are retracted to loosen the upper folded edge of the current garbage bag; the push rods of the second double-axis cylinder and the fourth double-axis cylinder remain extended, so that the drawstrings exposed at the upper folded edge opening and the lower folded edge opening of the current garbage bag are still pressed against the front support frame.

[0072] Compared with the prior art, the present invention has the following beneficial effects:

[0073] 1. The garbage bag of the present invention is in an open state when it is taken out, and the bag can be laid and used by relying on the gravity of the garbage without the assistance of any mechanism, which is convenient and easy;

[0112] Example 3

[0113] The present invention also provides a method for automatically packing garbage using the garbage bag set in Example 1 and the automatic garbage packing device in Example 2, such as Figure 1-Figure 8 As shown, the following steps are included:

[0114] Step S1: Install the garbage bag set 1 and adjust the position of the current garbage bag 2 to the initial position;

[0115] Step S2: Start the second motor 60301 to make the first synchronous belt 6030401 and the second synchronous belt 6030402 rotate forward, driving the two finger cylinder groups 60307 to rise to the top position and align with the lower folding edge 20202 of the current garbage bag 2;

[0116] Step S3: the first finger cylinder 6030701 and the second finger cylinder 6030702 perform a closing action to clamp the lower folded edge 20202 of the current garbage bag 2;

[0117] Step S4: Start the second motor 60301 to reverse the first synchronous belt 6030401 and the second synchronous belt 6030402, driving the two finger cylinder groups 60307 to descend to the bottom position, and the current garbage bag 2 is pulled down to the preset position;

[0118] Step S5: The push rods of the first double-axis cylinder 6030901, the second double-axis cylinder 6030902, the third double-axis cylinder 6030903 and the fourth double-axis cylinder 6030904 are extended to press the current garbage bag 2 onto the front support frame 60101;

[0119] Step S6: starting the first motor 504 to reverse the garbage bag reel 502, breaking the connection between the current garbage bag 2 and the next garbage bag 2 at the breakpoint 101, so that the current garbage bag 2 is separated from the garbage bag set 1;

[0120] Step S7: the flip push rod 604 is extended to flip the housing 601 and the internal component 603 from a vertical state to a horizontal state, so that the opening of the current garbage bag 2 faces upward;

[0121] Step S8: Pour the garbage into the current garbage bag 2, and the compressed bag body 201 of the current garbage bag 2 naturally droops and unfolds under the gravity of the garbage;

[0122] Step S9: the first finger cylinder 6030701 and the second finger cylinder 6030702 perform an opening action, the push rods of the first double-axis cylinder 6030901 and the third double-axis cylinder 6030903 are retracted, and the push rods of the second double-axis cylinder 6030902 and the fourth double-axis cylinder 6030904 remain extended, so that the folding piece 202 of the current garbage bag 2 is loosened while the drawstring 203 is still compressed, and the drawstring 203 is naturally tightened under the gravity of the garbage, and the opening of the current garbage bag 2 is closed;

[0123] Step S10: The push rods of the second double-axis cylinder 6030902 and the fourth double-axis cylinder 6030904 are retracted, the drawstring 203 is loosened, and the current garbage bag 2 with the opening tightened falls under the action of gravity and waits to be collected;

[0124] Step S11: flip the push rod 604 and retract it, restore the shell 601 and the internal component 603 from a horizontal state to a vertical state, and then jump back to step S2 if the garbage bag 2 is not used up, and jump back to step S1 if the garbage bag 2 is used up, and then re-execute the above process in sequence.

[0125] In step S1, the garbage bag group 1 is wound and installed on the garbage bag reel 502, and the first garbage bag 2 on the outermost layer of the garbage bag group 1 is the current garbage bag 2. The initial position of the current garbage bag 2 is located above the packaging mechanism 6 and passes through the gap between the front drum 50601 and the rear drum 50602. The lower folded edge 20202 of the current garbage bag 2 is located between the front support frame 60101 and the rear support frame 60102 and is aligned with the upper beam of the front support frame 60101.

[0126] In step S2, the second motor 60301 is started to rotate forward, which drives the first synchronous wheel 6030201 to rotate forward, and then drives the first synchronous belt 6030401 to rotate forward. The forward rotation of the first synchronous belt 6030401 drives the third synchronous wheel 6030203 to rotate forward, and the forward rotation of the third synchronous wheel 6030203 drives the synchronous shaft 60305 to rotate forward. The forward rotation of the synchronous shaft 60305 drives the fourth synchronous wheel 6030204 to rotate forward, and the forward rotation of the fourth synchronous wheel 6030204 drives the second synchronous belt 6030402 to rotate forward, finally making the first synchronous belt 6030401 and the second synchronous belt 6030402 rotate forward synchronously. The positive rotation of the first synchronous belt 6030401 drives the first finger cylinder 6030701 to move upward, and the positive rotation of the second synchronous belt 6030402 drives the second finger cylinder 6030702 to move upward. The first finger cylinder 6030701 and the second finger cylinder 6030702 have the same height and move synchronously. The first finger cylinder 6030701 and the second finger cylinder 6030702 are initially in an open state. When the first finger cylinder 6030701 and the second finger cylinder 6030702 rise to the top position of the corresponding synchronous belt, the lower folding edge 20202 of the current garbage bag 2 just extends into the opening of the first finger cylinder 6030701 and the second finger cylinder 6030702, and the lower folding edge 20202 is aligned with the clamping part of the first finger cylinder 6030701 and the second finger cylinder 6030702.

[0127] In step S4, the second motor 60301 is started to reverse, which drives the first synchronous wheel 6030201 to reverse, and then drives the first synchronous belt 6030401 to reverse. The reversal of the first synchronous belt 6030401 drives the third synchronous wheel 6030203 to reverse. The reversal of the third synchronous wheel 6030203 drives the synchronous shaft 60305 to reverse. The reversal of the synchronous shaft 60305 drives the fourth synchronous wheel 6030204 to reverse. The reversal of the fourth synchronous wheel 6030204 drives the second synchronous belt 6030402 to reverse, and finally the first synchronous belt 6030401 and the second synchronous belt 6030402 are reversed synchronously. The reversal of the first synchronous belt 6030401 drives the first finger cylinder 6030701 to move downward, and the reversal of the second synchronous belt 6030402 drives the second finger cylinder 6030702 to move downward. The first finger cylinder 6030701 and the second finger cylinder 6030702 have the same height and move synchronously. During this process, the first finger cylinder 6030701 and the second finger cylinder 6030702 remain in a closed state and clamp the lower fold 20202 of the current garbage bag 2, thereby pulling the current garbage bag 2 downward. When the first finger cylinder 6030701 and the second finger cylinder 6030702 drop to the bottom end position of the corresponding synchronous belt, the current garbage bag 2 is just pulled down to the preset position. The preset position of the current garbage bag 2 is located in the middle of the rear support frame 60102 and the front support frame 60101. At the preset position, the upper folded edge 20201 of the current garbage bag 2 is clamped in the middle of the upper beam of the front support frame 60101 and the upper beam of the rear support frame 60102. The upper folded edge opening 20205 of the current garbage bag 2 and the exposed drawstring 203 are facing the second double-axis cylinder 6030902 on the upper beam of the rear support frame 60102. The lower folded edge 20202 of the current garbage bag 2 is clamped in the middle of the lower beam of the front support frame 60101 and the lower beam of the rear support frame 60102. The lower folded edge opening 20206 of the current garbage bag 2 and the exposed drawstring 203 are facing the fourth double-axis cylinder 6030904 on the lower beam of the rear support frame 60102.

[0128] In step S5, the push rods of the first double-axis cylinder 6030901 and the third double-axis cylinder 6030903 extend to respectively press the upper folding edge 20201 of the current garbage bag 2 against the left and right sides of the upper beam of the front support frame 60101. The push rod of the second double-axis cylinder 6030902 extends to press the drawstring 203 exposed at the upper folding edge opening 20205 of the current garbage bag 2 against the center of the upper beam of the front support frame 60101. The push rod of the fourth double-axis cylinder 6030904 extends to press the drawstring 203 exposed at the lower folding edge opening 20206 of the current garbage bag 2 against the center of the lower beam of the front support frame 60101.

[0129] In step S6, the first finger cylinder 6030701 and the second finger cylinder 6030702 remain in a closed state, and the first double-axis cylinder 6030901, the second double-axis cylinder 6030902, the third double-axis cylinder 6030903 and the fourth double-axis cylinder 6030904 remain in an extended state, pressing the current garbage bag 2 against the front support frame 60101. Then, the first motor 504 is started to reverse and drive the first gear 50501 to reverse, the reverse rotation of the first gear 50501 drives the second gear 50502 to reverse, and the reverse rotation of the second gear 50502 drives the garbage bag reel 502 to reverse. The upper fold edge 20201 of the current garbage bag 2 is connected to the lower fold edge 20202 of the next garbage bag 2 via the breakpoint 101. When the garbage bag reel 502 is reversed, the next garbage bag 2 is pulled back upwards, and the breakpoint 101 between the two garbage bags 2 is broken after being stressed, thereby disconnecting the current garbage bag 2 from the next garbage bag 2, and the current garbage bag 2 is separated from the garbage bag set 1.

[0130] In step S9, the first double-axis cylinder 6030901 and the second double-axis cylinder 6030902 perform an opening action to loosen the lower folding edge 20202 of the current garbage bag 2; the push rods of the first double-axis cylinder 6030901 and the third double-axis cylinder 6030903 are retracted to loosen the upper folding edge 20201 of the current garbage bag 2; the push rods of the second double-axis cylinder 6030902 and the fourth double-axis cylinder 6030904 remain extended, so that the drawstring 203 exposed at the upper folding edge opening 20205 and the lower folding edge opening 20206 of the current garbage bag 2 are still pressed against the front support frame 60101.
