Description

Technical Field

[0001] The invention belongs to the field of tobacco processing equipment, and particularly relates to an automatic sealing feeding device and method for a ZB25 soft box packaging machine. Background Art

[0002] Generally speaking, the ZB25 soft box packaging machine is the mainstream medium-speed packaging machine in China. Its maximum packaging speed is 400 packs / minute, which means it can stick 400 seals per minute. The original sealing paper magazine is fixed, and it takes about 5,000 sheets to fully fill this sealing paper magazine (the thickness of sealing paper of different brands is different, so the number of seals added to the paper magazine varies). When the equipment runs at a speed of 380 packs / minute, seals need to be added every 13 minutes or so (seals must be added when there are about 1,500 sheets left, otherwise the positive pressure on the suction nozzle will be insufficient, causing the seals to not be sucked down in time). A normal shift runs for 8 hours, so the operator has to add seals at least 37 times. If there is a problem with the raw and auxiliary materials of the seals, the number of times the operator adds seals per shift will far exceed 37 times, and can even reach between 60 and 90 times. This increases the labor intensity of the operator and greatly affects work efficiency.

[0003] Therefore, how to provide a ZB25 soft box packaging machine automatic sealing feeding device has become a technical problem that needs to be solved urgently. Summary of the Invention

[0062] Preferably, a method for using the automatic sealing feeding device of a ZB25 soft box packaging machine comprises the following steps:

[0063] S1, first fill each sealing paper slot (1a) of the storage drum (1) with sealing paper (2);

[0064] S2, initializing the storage drum (1) so that one of the sealing paper slots (1a) is aligned with the blanking slot opening of the blanking bin (4), wherein the sealing limit assembly (6) below the sealing paper slot (1a) is in a paper placing state;

[0065] S3, when the sealing paper (2) in the drop bin (4) is lower than the preset detection range of the detection device (5), the detection device (5) sends a paper shortage signal to the control system;

[0066] S4, after the control system receives the paper shortage signal from the detection device (5), the control system sends a rotation instruction to the driving device, and after the storage roller (1) rotates to the right position, the sealing limit assembly (6) performs the paper release operation;

[0068] S6, after the control system receives the paper out signal, the control system sends a rotation instruction to the drive motor (3);

[0069] S7, after the driving motor (3) drives the storage roller (1) to rotate to the right position, the sealing limit assembly (6) immediately performs the paper feeding operation;

[0070] S8, as time goes by, when the detection device (5) sends a paper shortage signal to the control system again, repeat the above steps S5-S7;

[0071] S9. Finally, as time goes by, when the sealing paper detector (16) sends a paper-out signal to the control system, the control system immediately sends a paper-out reminder to the external display device and issues an alarm, prompting the operator to add paper to each sealing paper slot (1a).

[0072] In the present invention, a sealing paper detector (16) is used to detect whether sealing paper (2) is stored in a corresponding sealing paper slot (1a). The sealing paper detector (16) is connected to a control system. When the sealing paper detector (16) detects that there is no sealing paper (2), the sealing paper detector (16) sends a paper-out signal to the control system. When the control system receives the paper-out signal sent by the sealing paper detector (16), the control system sends a paper-out reminder to an external display device and issues an alarm.

[0073] The plurality of connection cover plate mounting holes respectively correspond to the shapes of the drive shaft (3a) of the drive motor (3), the drive shaft (9a) of the transmission gear assembly (9), the first driven assembly (10), the second driven assembly (11), the positioning assembly (12), and the ball bearing (13);

[0074] The driving base body is a structure with a hollow interior and an open top; a plurality of mounting holes for connecting and adapting to various components are also provided in the driving base body; and the driving base body and the connecting cover plate (7a) are detachably connected.

[0075] In the present invention, the driving motor (3) is a servo motor, and the detecting device (5) is a photoelectric detector; the detecting device (5), the second seal limiting structure of the seal limiting assembly (6), the driving motor (3) of the driving device, and the sealing paper detector (16) are respectively connected to the control system.

[0076] The working principle of the first seal limiting structure adopted in the present invention is:

[0077] During initial installation, the operator adjusts any one of the sealing paper slots (1a) of the storage drum (1) to a phase aligned with the blanking slot of the blanking bin (4) by driving the motor (3);

[0078] When in use, the default state of the sealing limit assembly (6) corresponding to the sealing paper slot (1a) aligned with the drop bin (4) is that the bottom roller is tightly attached to the groove of the sealing stand (14), the first spring (6b) is stretched out, and the fork pin (6c) of the sealing limit assembly (6) does not extend from the sealing paper slot insertion hole at the bottom of the sealing paper slot (1a), and the default state of the sealing limit assembly (6) corresponding to the remaining sealing paper slots (1a) is that the fork pin (6c) extends from the sealing paper slot insertion hole at the bottom of the sealing paper slot (1a), and the first spring (6b) is compressed and has a pre-tightening force; when any one of the sealing paper slots (1a) is aligned with the drop bin (4), the sealing paper (2) in the corresponding sealing paper slot (1a) can fall down accurately;

[0079] When the detection device (5) sends a paper shortage signal to the control system, the control system sends an instruction to the drive motor (3) to rotate one station, and the roller hopper (1) rotates under the drive device. After the roller hopper (1) rotates 45 degrees, the drive motor (3) stops rotating, and the next sealing paper slot (1a) of the roller hopper (1) is aligned with the drop bin (4) again. The third roller (6a) of the sealing limit assembly (6) corresponding to the next sealing paper slot (1a) moves again into the groove of the sealing platform (14), and the first spring (6b) rebounds to retract the fork needle (6c) from the sealing paper slot insertion hole at the bottom of the sealing paper slot (1a) into the inside. The sealing paper (2) in the sealing paper slot (1a) can be added downward again until the amount of the sealing paper (2) is reduced to a low material level that can be detected by the detection device (5), and then the next working cycle starts to continue working.

[0080] As the equipment operates, the amount of sealing paper (2) in the sealing paper slot (1a) gradually decreases, and the material level gradually decreases. When the level decreases to a level that triggers the detection device (5), i.e., the photoelectric detector, the detection device (5) sends an electrical signal to control the drive motor (3) to move. The rotation of the drive motor (3) drives the rotation of the transmission gear assembly (9), which then drives the rotation of the first driven assembly (10) and the second driven assembly (11), and finally drives the rotation of the roller hopper (1), and the sealing paper slot (1a) also changes position accordingly.

[0081] When the sealing paper detector (16) detects that the corresponding sealing paper slot (1a) has no sealing paper (2), the sealing paper detector (16) sends a paper-out signal to the control system. When the control system receives the paper-out signal from the sealing paper detector (16), the control system sends a paper-out reminder to an external display device and issues an alarm, prompting the operator to add paper.

[0082] The working principle of the second seal limiting structure adopted in the present invention is:

[0083] During initial installation, the operator adjusts any one of the sealing paper slots (1a) of the storage drum (1) to a phase aligned with the blanking slot of the blanking bin (4) by driving the motor (3);

[0084] When in use, the default state of the sealing limit assembly (6) corresponding to the sealing paper slot (1a) aligned with the drop bin (4) is that the "L"-shaped connecting rod of the cylinder assembly (15) compresses the label paper drag plate (6d) toward the fixed plate (6g), the second spring (6f) is compressed and has a pre-tightening force, and the label paper drag plate (6d) of the sealing limit assembly (6) does not extend from the sliding groove at the bottom of the sealing paper slot (1a), and the default state of the label paper drag plates (6d) corresponding to the remaining sealing paper slots (1a) is that they extend from the sliding groove at the bottom of the sealing paper slot (1a), and the second spring (6f) is extended; when any one of the sealing paper slots (1a) is aligned with the drop bin (4), the sealing paper (2) in the corresponding sealing paper slot (1a) can accurately fall downward;

[0085] When the detection device (5) sends a paper shortage signal to the control system, the control system sends an instruction to the drive motor (3) to rotate one station, and the roller hopper (1) rotates under the drive device. After the roller hopper (1) rotates 45 degrees, the drive motor (3) stops rotating and sends a signal to the cylinder assembly (15) through the control system. The next sealing paper slot (1a) of the roller hopper (1) is aligned with the drop bin (4) again, and the label paper drag plate (6d) corresponding to the next sealing paper slot (1a) is compressed again by the "L"-shaped connecting rod of the cylinder assembly (15) toward the fixed plate (6g). The second spring (6f) is compressed and has a pre-tightening force, and the label paper drag plate (6d) retracts from the sliding groove at the bottom of the sealing paper slot (1a) into the interior, and the sealing paper (2) in the sealing paper slot (1a) can be added downward again until the amount of sealing paper (2) is reduced to a low material level that can be detected by the detection device (5), and then the next working cycle starts to continue working.

[0086] As the equipment operates, the amount of sealing paper (2) in the sealing paper slot (1a) gradually decreases, and the material level gradually decreases. When the level decreases to a level that triggers the detection device (5), i.e., the photoelectric detector, the detection device (5) sends an electrical signal to control the drive motor (3) to move. The rotation of the drive motor (3) drives the rotation of the transmission gear assembly (9), which then drives the rotation of the first driven assembly (10) and the second driven assembly (11), and finally drives the rotation of the roller hopper (1), and the sealing paper slot (1a) also changes position accordingly.

[0087] When the sealing paper detector (16) detects that the corresponding sealing paper slot (1a) has no sealing paper (2), the sealing paper detector (16) sends a paper-out signal to the control system. When the control system receives the paper-out signal from the sealing paper detector (16), the control system sends a paper-out reminder to an external display device and issues an alarm, prompting the operator to add paper.

[0088] Compared with the prior art, the present invention has the following beneficial effects:

[0089] 1. The present invention reduces the labor intensity of the staff: by using an automated feeding device, compared with the staff frequently manually adding sealing paper, the labor intensity of the staff is greatly reduced.

[0090] 2. The present invention significantly improves work efficiency: since the manual feeding process is reduced, the equipment can run continuously for a longer period of time without frequent shutdowns to wait for feeding, thereby improving the work efficiency of the entire tobacco packaging process.

[0091] 3. The present invention can accurately control the feeding: the amount of sealing paper in the sealing paper slot is monitored in real time by a detection device. When the preset low material level is reached, the drive motor is automatically triggered to perform the feeding operation, ensuring the timely supply of sealing paper and avoiding production interruptions caused by insufficient sealing paper.

[0092] 4. The present invention can improve production quality: due to the timely supply and precise control of sealing paper, production quality problems caused by insufficient sealing paper or untimely addition of sealing paper, such as loose sealing and misalignment, are reduced;

[0093] 5. Since the present invention is provided with a sealing paper detector, the operator can set the sealing paper detector position according to the specific usage situation, thereby increasing the buffer time for adding sealing paper;

[0094] 6. The present invention is provided with a sealing paper detector. When the sealing paper detector sends a paper-out signal to the control system, the control system can send a paper-out reminder and an alarm to an external display device, prompting the operator to add paper, thereby increasing convenience;

[0095] 7. The present invention can also set several signal instructions for the detection device through the control system, and can send different signal instructions to the control system according to multiple preset paper adding time lengths to prevent a backup paper adding solution from having problems with the sealing paper detector, or a reminder solution that the equipment is still running when there is a problem with the sealing limit component and paper is not added.

[0194] In summary, a more specific embodiment of the present invention is:

[0195] Example 1

[0196] When the first seal limit structure design is adopted:

[0197] like Figure 4 As shown, during the initial installation, the operator drives the motor 3 to adjust any one of the sealing paper slots 1a of the storage drum 1 to a phase aligned with the blanking slot of the blanking bin 4;

[0198] like Figure 1 — Figure 3 As shown, the default state of the sealing limit assembly 6 corresponding to the sealing paper slot 1a aligned with the blanking bin 4 is that the bottom roller is tightly against the groove of the sealing base 14, the first spring 6b is stretched, and the fork pin 6c of the sealing limit assembly 6 does not extend from the sealing paper slot insertion hole at the bottom of the sealing paper slot 1a, and the fork pin 6c of the sealing limit assembly 6 corresponding to the remaining sealing paper slots 1a is extended from the sealing paper slot insertion hole at the bottom of the sealing paper slot 1a by default, and the first spring 6b is compressed and has a pre-tightening force; when any one of the sealing paper slots 1a is aligned with the blanking bin 4, the sealing paper 2 in the corresponding sealing paper slot 1a can fall down accurately;

[0199] When the detection device 5 sends a paper out signal to the control system, the control system sends an instruction to the drive motor 3 to rotate one station, and the roller hopper 1 rotates under the drive of the drive device. After the roller hopper 1 rotates 45 degrees, the drive motor 3 stops rotating, and the next sealing paper slot 1a of the roller hopper 1 is aligned with the drop bin 4 again. The third roller 6a of the sealing limit assembly 6 corresponding to the next sealing paper slot 1a moves again into the groove of the sealing base 14, and the first spring 6b rebounds to retract the fork needle 6c from the sealing paper slot insertion hole at the bottom of the sealing paper slot 1a. The sealing paper 2 in the sealing paper slot 1a can be fed downward again until the amount of sealing paper 2 is reduced to a low material level that can be detected by the detection device 5, and then the next working cycle is started to continue working;

[0200] As the equipment runs, the amount of sealing paper 2 in the sealing paper slot 1a gradually decreases, and the material level gradually drops. When it drops to the point where the detection device 5, i.e., the photoelectric detector, is triggered, the detection device 5 sends an electrical signal to control the movement of the drive motor 3. The rotation of the drive motor 3 drives the rotation of the transmission gear assembly 9, which then drives the rotation of the first driven assembly 10 and the second driven assembly 11, and finally drives the rotation of the roller hopper 1, and the sealing paper slot 1a also changes its position accordingly.

[0201] When the sealing paper detector 16 detects that there is no sealing paper 2 in the corresponding sealing paper slot 1a, the sealing paper detector 16 sends a paper-out signal to the control system. When the control system receives the paper-out signal sent by the sealing paper detector 16, the control system sends a paper-out reminder to the external display device and issues an alarm, prompting the operator to add paper.

[0202] During the above-mentioned use, the sealing paper detector 16 is connected to the driving base 7 at the lower part of the sealing paper slot 1a on the right side of the feeding bin 4 through the bracket, that is, there is another sealing paper slot 1a between the sealing paper slot 1a above the sealing paper detector 16 and the sealing paper slot 1a above the feeding bin 4;

[0203] The operator can also calculate the total time of adding the sealing paper 2 according to the time it takes for all the sealing paper 2 to be added to the storage drum 1, and then reasonably arrange the time of adding the sealing paper 2 to the storage drum 1, which greatly reduces the labor intensity of the staff;

[0204] The operator can also set several paper-out signals and paper-out signal sending times of the detection device 5 through the control system to prevent a backup plan from having problems with the sealing paper detector 16; when the detection device 5 sends a paper-out electrical signal to the control system, and the control system controls the drive motor 3 to move, the detection device 5 exceeds the first predetermined sealing paper adding time, but still does not detect the addition of sealing paper 2, then the detection device 5 sends a paper-out signal to the control system. When the control system receives the paper-out signal sent by the detection device 5, the control system sends a paper-out reminder and an alarm to the external display device, prompting the operator to add paper; if the detection device 5 exceeds the second predetermined sealing paper adding time, but still does not detect the addition of sealing paper 2, a secondary paper-out signal is sent to the control system, and the control system controls the equipment to shut down, and sends a paper-out reminder and an alarm and a shutdown display to the external display device, to prevent a backup paper adding plan from having problems with the sealing paper detector, or a reminder plan in which the sealing limit component has a problem and does not put paper, and the equipment is still running.

[0205] Example 2

[0206] When the second seal limit structure design is adopted:

[0207] like Figure 4 As shown, during the initial installation, the operator drives the motor 3 to adjust any one of the sealing paper slots 1a of the storage drum 1 to a phase aligned with the blanking slot of the blanking bin 4;

[0208] Furthermore, when in use, the default state of the sealing limit assembly 6 corresponding to the sealing paper slot 1a aligned with the drop bin 4 is that the "L"-shaped connecting rod of the cylinder assembly 15 compresses the label paper drag plate 6d toward the fixed plate 6g, the second spring 6f is compressed and has a pre-tightening force, and the label paper drag plate 6d of the sealing limit assembly 6 does not extend from the chute at the bottom of the sealing paper slot 1a, and the default state of the label paper drag plates 6d corresponding to the remaining sealing paper slots 1a is to extend from the chute at the bottom of the sealing paper slot 1a, and the second spring 6f is extended; when any one of the sealing paper slots 1a is aligned with the drop bin 4, the sealing paper 2 in the corresponding sealing paper slot 1a can fall down accurately;

[0209] When the detection device 5 sends a paper out signal to the control system, the control system sends an instruction to the drive motor 3 to rotate one station, and the roller hopper 1 rotates under the drive of the drive device. After the roller hopper 1 rotates 45 degrees, the drive motor 3 stops rotating and sends a signal to the cylinder assembly 15 through the control system. The next sealing paper slot 1a of the roller hopper 1 is aligned with the drop bin 4 again, and the label paper drag plate 6d corresponding to the next sealing paper slot 1a is again compressed toward the fixed plate 6g by the "L"-shaped connecting rod of the cylinder assembly 15. The second spring 6f is compressed and has a pre-tightening force, and the label paper drag plate 6d retracts from the slide groove at the bottom of the sealing paper slot 1a to the inside, and the sealing paper 2 in the sealing paper slot 1a can be fed downward again until the amount of sealing paper 2 is reduced to a low material level that can be detected by the detection device 5, and then the next working cycle is started to continue working.

[0210] As the equipment runs, the amount of sealing paper 2 in the sealing paper slot 1a gradually decreases, and the material level gradually drops. When it drops to the point where the detection device 5, i.e., the photoelectric detector, is triggered, the detection device 5 sends an electrical signal to control the movement of the drive motor 3. The rotation of the drive motor 3 drives the rotation of the transmission gear assembly 9, which then drives the rotation of the first driven assembly 10 and the second driven assembly 11, and finally drives the rotation of the roller hopper 1, and the sealing paper slot 1a also changes its position accordingly.

[0211] When the sealing paper detector 16 detects that there is no sealing paper 2 in the corresponding sealing paper slot 1a, the sealing paper detector 16 sends a paper-out signal to the control system. When the control system receives the paper-out signal sent by the sealing paper detector 16, the control system sends a paper-out reminder to the external display device and issues an alarm, prompting the operator to add paper.

[0212] During the above-mentioned use, the sealing paper detector 16 is connected to the driving base 7 at the lower part of the sealing paper slot 1a on the right side of the feeding bin 4 through the bracket, that is, there is another sealing paper slot 1a between the sealing paper slot 1a above the sealing paper detector 16 and the sealing paper slot 1a above the feeding bin 4;

[0213] When the control system issues a rotation instruction to the drive motor 3, the control system will simultaneously send a reset signal to the cylinder assembly 15, so as to facilitate the paper placement work with the paper supporting structure under the next sealing paper slot 1a; the operator can also calculate the total time for adding the sealing paper 2 based on the time it takes to add all the sealing papers 2 to the storage drum 1, and then reasonably arrange the time for adding the sealing paper 2 to the storage drum 1, which greatly reduces the labor intensity of the staff.

[0214] The operator can also set several paper-out signals and paper-out signal sending times of the detection device 5 through the control system to prevent a backup plan from having problems with the sealing paper detector 16; when the detection device 5 sends a paper-out electrical signal to the control system, and the control system controls the drive motor 3 to move, the detection device 5 exceeds the first predetermined sealing paper adding time, but still does not detect the addition of sealing paper 2, then the detection device 5 sends a paper-out signal to the control system. When the control system receives the paper-out signal sent by the detection device 5, the control system sends a paper-out reminder and an alarm to the external display device, prompting the operator to add paper; if the detection device 5 exceeds the second predetermined sealing paper adding time, but still does not detect the addition of sealing paper 2, a secondary paper-out signal is sent to the control system, and the control system controls the equipment to shut down, and sends a paper-out reminder and an alarm and a shutdown display to the external display device, to prevent a backup paper adding plan from having problems with the sealing paper detector, or a reminder plan in which the sealing limit component has a problem and does not put paper, and the equipment is still running.
