Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to an auxiliary device for detecting the remaining amount of trademark paper. Background Art

[0002] Reducing costs and increasing efficiency has always been the core goal of the tobacco industry. The modern tobacco industry has greatly improved production efficiency and quality through production automation, and to a certain extent, has achieved the goal of reducing costs and increasing efficiency. However, in the actual production process, there are still cases where the entire production line stops running due to the low automation accuracy of some links, which seriously restricts the production efficiency of cigarettes.

[0003] The existing cigarette packaging machines are basically composed of the body, transmission, cigarette storage, lining paper, trademark, and sealing parts. The packaging process is as follows: when the machine is started, the cigarettes in the cigarette storage hopper are input and output from the horizontal box mold in a neat arrangement of "7, 6, 7" (a total of 20 cigarettes); when passing through the lining paper part, the lining paper is sealed and the lining paper is folded on both sides in the flue; when passing through the trademark part, the trademark paper is sealed and the label paper is glued and folded on both sides in the flue; finally, when passing through the sealing part, the seal is affixed, thus completing the entire cigarette packing process. Among them, the efficient and economical use of trademark paper has always been a technical difficulty when it is wrapped.

[0004] In the prior art, the label paper reel feeding section can mostly realize the function of automatically detecting and replacing the label paper. Taking the GDX6S packaging machine as an example, Figure 7 , 8 The basic structure of the remaining amount detection mechanism of the trademark paper is that the roller 4 (equivalent to the overlapping block 7 in the present invention) on one end of the pressure rod 8 is pressed on the outer periphery of the reel trademark paper 2, and the other end of the pressure rod 8 passes through the through hole of the side wall of the reel 10 and is connected to the connecting rod mechanism inside the reel 10. The connecting rod mechanism is equipped with a sensing sheet 101. When detecting the remaining amount of the trademark paper, as the diameter of the reel trademark paper 2 decreases, the positions of the pressure rod 8 and the sensing sheet 101 change with the decrease in the diameter of the reel trademark paper 2. The diameter detector 102 in the reel 10 indirectly determines the remaining amount of the reel trademark paper 2 by detecting the position of the sensing sheet 101. When the sensing sheet 101 reaches the preset position, the diameter detector 102 transmits the signal to the inductive switch (not shown in the figure), and the inductive switch sends an overlapping signal, thereby starting the overlapping and completing the replacement. However, in actual use, it was found that the use of the existing trademark paper reel-type feeding section for automatic overlapping process often leads to two problems: 1. There is still a lot of trademark paper left but new trademark paper is overlapped, resulting in waste of auxiliary materials; 2. The trademark paper is exhausted but the new trademark paper is not overlapped, resulting in paper breakage and equipment shutdown.

[0005] The utility model aims to solve the above problems. Utility Model Content

A limiting pin 511 protruding from the inner side wall of the fixed seat 51 is accommodated in the first slide groove 522. A return spring is sleeved on the outer wall of the moving rod 52 between the flange 521 and the limiting pin 511. 56, one end of the return spring 56 is against the flange 521, and the other end is against the limit pin 511; the second sliding groove 523 of the movable rod 52 is slidably connected with the pin on the first connecting arm 551 of the triangular plate 55, the second connecting arm 552 of the triangular plate 55 is hinged to the top end of the connecting rod 54, the third connecting arm 553 of the triangular plate 55 is rotatably connected to the side wall of the fixed seat 51, the bottom end of the connecting rod 54 is hinged to the top end of the contact 53, and the lower end of the contact 53 passes through the bottom of the fixed seat 51 and is slidably connected to the bottom of the fixed seat 51.

[0012] The positional relationship between the above parts is as follows:

[0013] The placement seat 3 is arranged above the reel label paper 2, and the two rollers 4 of the placement seat 3 are in rolling contact with the outer wall of the reel label paper 2, and the overlap block 7 is arranged in the groove body of the placement seat 3 and can be taken out from the top opening of the placement seat 3, and the two "U"-shaped grooves of the placement seat 3 are respectively the downward sliding channels of the connecting shaft 81 and the cantilever rod 9;

[0014] The fixed seat 51 is arranged on the rear side of the placement seat 3, and the first end of the moving rod 52 in the fixed seat 51 extends from the open end of the fixed seat 51 and passes through the through hole 31 of the front and rear side walls of the placement seat 3 to contact the top surface of the stopper 6, and the cantilever rod 9 contacts the top surface of the other end of the stopper 6; the lower end of the contact 53 is facing the outer peripheral frame of the reel frame 1; before the reel trademark paper 2 is used up, the contact 53 fails to conflict with the outer peripheral frame of the reel frame 1, and the front end of the moving rod 52 restricts the stopper 6, so that the stopper 6 keeps intercepting the cantilever rod 9, thereby preventing the overlap block 7 from falling to the bottom of the placement seat 3.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the actual operation process, the angle of the pressure rod 8 changes as the amount of trademark paper decreases. As the amount of trademark paper decreases, the pressure rod 8 slowly approaches the overlapping signal trigger switch in the reel. When the pressure rod 8 rotates to a certain angle, the overlapping signal trigger switch in the reel is triggered, and the equipment starts to overlap. However, due to the different diameters of the reel inner cores of the reel trademark paper, the triggering timing of the trademark paper reel overlapping signal cannot be guaranteed to be consistent, and is often earlier or later than the ideal situation. The utility model sets the distance between the contact 53 and the outer peripheral frame of the reel frame 1 in advance as needed, controls the timing of the pressure rod 8 sending the overlapping signal, and completely solves the problem of the overlapping signal being sent too early or too late.

[0021] 2. The auxiliary device of the utility model does not require any modification to the original equipment. The device raises the pressure rod by a certain distance to avoid the pressure rod 8 sending out a lap signal too early, and at the same time adds a mechanical contact with a lever adjustment to control the timing of the pressure rod 8 sending out a lap signal.

[0022] 3. The utility model provides two rollers at the bottom of the placement seat, which effectively ensures that the placement seat is always in a relatively stable state during the operation of the equipment, and can apply pressure to the trademark paper to prevent the trademark paper from wrinkling or deviating from the center of the circle.

Any changes or improvements made based on the teachings of the present invention fall within the scope of protection of the present invention. If no specific technology or conditions are specified in the examples, the technology or conditions described in the literature in the field or the product instructions shall be followed.

[0034] like Figure 7 , 8 As shown, an auxiliary device for detecting the remaining amount of trademark paper includes a reel 10, a reel frame 1, a reel trademark paper 2 and a pressure rod 8. The reel frame 1 is arranged on the side wall of the reel 10, and the reel trademark paper 2 is sleeved on the core shaft 11 of the reel frame 1. One end of the pressure rod 8 is connected to a lap block 7 through a connecting shaft 81, and the other end of the pressure rod 8 passes through a through hole in the side wall of the reel 10 and is connected to a detection mechanism in the reel 10. The outer side wall of the lap block 7 is provided with a protruding cantilever rod 9 along the extension direction parallel to the core shaft 11, as shown in FIG. Figure 1-3 As shown, the auxiliary device further includes: a placement seat 3, a trigger assembly 5, and a stopper 6;

[0035] like Figure 4 As shown, the placement seat 3 is a trough structure with at least a top opening, two rollers 4 are symmetrically arranged on both sides of the bottom end of the placement seat 3, and two "U"-shaped grooves are respectively opened on the front and rear side walls of the placement seat 3, and one side of the two "U"-shaped grooves is opened with a through hole 31 that penetrates the front and rear side walls of the placement seat 3;

[0036] like Figure 5As shown, the trigger assembly 5 includes a fixed seat 51 and a moving rod 52, a contact 53, a connecting rod 54 and a triangular plate 55 arranged inside the fixed seat 51. A flange 521 is partially provided in the direction of the first end of the moving rod 52. A first slide groove 522 and a second slide groove 523 are respectively provided between the flange 521 and the second end of the moving rod 52. A limiting pin 511 protruding from the inner side wall of the fixed seat 51 is accommodated in the first slide groove 522. A return spring 56 is sleeved on the outer wall of the moving rod 52 between the flange 521 and the limiting pin 511. One end of the return spring 56 is against the flange 521, and the other end is against the limiting pin 511. The second sliding groove 523 of the movable rod 52 is slidably connected with the pin on the first connecting arm 551 of the triangular plate 55, the second connecting arm 552 of the triangular plate 55 is hinged to the top of the connecting rod 54, the third connecting arm 553 of the triangular plate 55 is rotatably connected to the side wall of the fixed seat 51, the bottom end of the connecting rod 54 is hinged to the top of the contact 53, the lower end of the contact 53 passes through the bottom of the fixed seat 51 and is slidably connected to the bottom of the fixed seat 51, and the sliding connection between the bottom of the fixed seat 51 and the contact 53 can limit the contact 53 in the radial direction, thereby ensuring that the contact 53 can move up and down in a direction perpendicular to the bottom of the fixed seat 51.

[0037] like Figure 1 , 4 As shown, the stopper 6 is connected to the lower part of the through hole 31 of the front side wall of the placement seat 3 through a fixed shaft 61, and the stopper 6 can freely rotate along the circumferential outer wall of the fixed shaft 61;

[0038] like Figure 1-4 As shown, the positional relationship between the above-mentioned parts is as follows:

[0039] The placement seat 3 is arranged above the reel label paper 2, and the two rollers 4 of the placement seat 3 are in rolling contact with the outer wall of the reel label paper 2, allowing the rollers 4 to move toward the center of the reel frame 1 as the reel label paper 2 is reduced. At the same time, the arrangement of the two rollers 4 also reduces the friction and damage to the label paper, ensuring the surface quality of the label paper; the overlap block 7 is arranged in the groove body of the placement seat 3 and can be taken out from the top opening of the placement seat 3. The two "U"-shaped grooves of the placement seat 3 are respectively the downward sliding channels of the connecting shaft 81 and the cantilever rod 9;

[0040] The fixed seat 51 is arranged at the rear side of the placement seat 3. Before the auxiliary device is triggered, the first end of the moving rod 52 in the fixed seat 51 passes through the through hole 31 of the front and rear side walls of the placement seat 3 and contacts the upper surface of one end of the stopper 6, and the cantilever rod 9 contacts the upper surface of the other end of the stopper 6; the lower end of the contact 53 is directly facing the outer peripheral frame of the reel rack 1; before the reel label paper 2 is used up, the contact 53 fails to collide with the outer peripheral frame of the reel rack 1, and the front end of the moving rod 52 restricts the stopper 6, so that the stopper 6 keeps intercepting the cantilever rod 9, thereby preventing the overlap block 7 from falling to the bottom of the placement seat 3. Before and after the auxiliary device is triggered, the first end of the moving rod 52 in the fixed seat 51 cancels the contact with the upper surface of one end of the stopper 6, and the cantilever rod 9 falls to the bottom of the placement seat by its own gravity, and the stopper 6 also returns to a vertical state by its own gravity.

[0041] The overlap block 7 moves up and down as the remaining amount of the trademark paper changes, while driving the pressure rod 8 to rotate. The function of the stopper 6 is to prevent the overlap block 7 from entering the bottom of the placement seat too early when the trademark paper has not been used to a predetermined remaining amount, thereby ensuring the detection accuracy and timeliness of the operation of the entire system.

[0042] The main function of the above-mentioned cantilever rod 9 is to provide a manual intervention mechanism, so that the operator can manually lift the integral pressure rod 8 under specific circumstances. The introduction of this design provides more flexibility and controllability for the equipment. When equipment maintenance or sudden overlap problems need to be solved, the operator can directly lift the pressure rod 8 manually through the cantilever rod 9 without having to rely entirely on the automatic control system. This not only ensures the continuous operation of the production line when the detection system fails or requires maintenance, but also provides the operator with a means of direct intervention to deal with unforeseen emergencies.

[0043] like Figure 5 , 6 As shown, the contact 53 includes a connecting rod 531 and a contact round head 532. The lower end of the connecting rod 531 passes through the bottom of the fixed seat 51 and is movably connected with the contact round head 532. The contact round head 532 is opposite to the frame of the reel rack 1, allowing the contact round head 532 to be finely adjusted in the vertical direction as needed to adapt to the specific differences of different machines. By adjusting the distance between the connecting rod 531 and the contact round head 532, the distance between the contact round head 532 and the outer wall of the frame of the reel rack 1 is adjusted, and personalized adjustment can be achieved according to different machines.

[0044] like Figure 6 As shown, the side wall of the contact round head 532 is also provided with a positioning pin 533, which is movably abutted against the connecting rod 531. After adjusting the distance from the contact 53 to the frame of the reel frame 1, it can ensure that the connecting rod 531 is firmly connected to the contact round head, further improving the stability of the auxiliary device (not shown in the figure).

[0045] like Figure 1 , 4 As shown, the stopper 6 is a rectangular block.

[0046] Working principle:

[0047] When in use, adjust the contact 53 to a predetermined position, adjust the stopper 6 to a horizontal state, place the placement seat 3 under the pressure rod 8, adjust the position of the placement seat 3 so that the cantilever rod 9 and the connecting shaft 81 are directly opposite to the two "U"-shaped grooves of the placement seat 3, place the overlap block 7 into the placement seat 3 from the top opening of the placement seat 3, and make the two rollers 4 contact the outer wall of the reel label paper 2. At this time, the stopper 6 is in a horizontal position, and the outward end of the moving rod 52 is pressed on the upper surface of the stopper 6. The stopper 6 limits the cantilever rod 9, and the overlap block 7 is in a suspended position. As the reel label paper 2 is reduced, the contact 53 is in contact. When the reel label paper 2 is reduced to the point where the contact 53 contacts the outer wall of the frame of the reel frame 1, the contact 53 pushes upward, and through the mechanical linkage of the connecting rod 54 and the triangular plate 55, the moving rod 52 is prompted to move backward to overcome the elastic force of the spring 56. When the first end of the moving rod 52 no longer restrains the stopper 6, the stopper 6 returns to a vertical state, and the other end of the stopper 6 can no longer block the cantilever rod 9. The overlap block 7 carries the pressure rod 8 down along the U-shaped groove, and the sensor 102 in the reel 10 detects the approach of the falling pressure rod 8 through the sensor sheet 101 on the connecting rod mechanism, thereby triggering the label paper to overlap. The distance between the contact 53 and the outer wall of the frame of the reel frame 1 can be finely adjusted as needed to adapt to the differences between different machines.
