Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco equipment, in particular to a cigarette box bottom rear folding device suitable for a YP114 case filling and sealing machine. Background Art
[0002] The existing cigarette packaging section generally uses the YP114 case filling and sealing machine to fold the edges of the cigarette boxes, wherein the folding work of the bottom edge of the cigarette box is mainly completed by the cooperation of the front folding device and the rear folding device. The above-mentioned rear folding device mainly includes a frequency conversion controller, a rodless cylinder, a slider, a slide, a folding plate, and a linear module. The top end of the slider is connected to the bottom end of the linear module, the bottom end of the slider is slidably connected to the slide, the side wall of the slider is connected to the driving end of the rodless cylinder, and the folding plate is installed on the top end of the linear module. When the rear folding device is working, the driving end of the rodless cylinder pushes the slider to push the folding plate in the direction away from the fixed end of the rodless cylinder until it reaches the folding station, and then the slider stops moving. At the same time, the folding plate folds the bottom edge of the cigarette box along the indentation. After the folding work is completed, the driving end of the rodless cylinder drives the slider to drive the folding plate back to the fixed end of the rodless cylinder drive. When the folding work is performed again, the above process is repeated.
[0003] However, in actual production, it was discovered that the hem folded by the rear folding device often did not fold along the hem indentation, ultimately causing the cigarette box to fail to fold. To address this, the inventors conducted a lengthy on-site investigation and discovered that these hem folding failures were primarily caused by the hem folding plate in the rear folding device not stopping at the correct position before folding, resulting in the failure of the bottom hem of the cigarette box to fold.
[0004] There are two main reasons why the folding plate cannot stop accurately at the folding station:
[0005] 1. Due to the frequent and high-speed back-and-forth movement of the slider, the slider and the slide groove are seriously aged and worn, causing the slider to shake during the sliding process and deviate from the preset sliding position in the direction perpendicular to the sliding direction of the slider, thereby causing the folding plate to not stop accurately at the folding station;
[0006] 2. The existing rear folding device uses the speed control mode of the frequency converter to control the rodless cylinder and thus control the sliding stop position of the folding plate. However, the speed control mode has slow response, low accuracy, and poor stability. It cannot always ensure that the slider slides and stops accurately in the sliding direction, which causes the folding plate to not stop accurately at the folding station.
[0007] In order to solve at least one of the above problems, the present utility model is proposed. Utility Model Content
[0008] The utility model provides a rear folding device for the bottom of a cigarette box suitable for a YP114 case filling and sealing machine. The device effectively avoids the problem that the slide groove guides the slide groove inaccurately due to aging and wear of the slide groove and the slide groove, thereby causing the folding plate to stop at an inaccurate position, and avoids the problem that the slide cannot be accurately stopped in the moving direction due to reasons such as slow response, low precision and poor stability of frequency conversion control.
[0009] The utility model adopts the following technical solutions to solve the above problems:
[0010] The utility model provides a cigarette box bottom rear folding device suitable for a YP114 case filling and sealing machine, the rear folding device comprising: a base 1, a SEW servo driver 2, a slide 3, a linear module 4, a folding plate 5, and a transmission mechanism 6;
[0011] The base 1 is connected to the guide rods 11 on both sides, and the two sides of the slider 3 are respectively slidably connected to the guide rods 11 on both sides of the base 1;
[0012] The SEW servo driver 2 is fixed to one end of the base 1, and one end of the transmission mechanism 6 is rotatably connected to the SEW servo driver 2, and the other end is rotatably connected to the other end of the base 1;
[0013] The bottom of the slider 3 is fixedly connected to the transmission mechanism 6, and the SEW servo driver 2 drives the transmission mechanism 6 to drive the slider 3 to slide along the extending direction of the guide rod 11;
[0014] The top of the slider 3 is connected to the fixed end of the linear module 4, and the movable end of the linear module 4 is connected to the folding plate 5, so that the sliding direction of the folding plate 5 on the linear module 4 is perpendicular to the sliding direction of the slider 3.
[0015] Preferably, the rear folding device further includes a folding plate support frame 7 , and the folding plate support frame 7 is connected between the folding plate 5 and the moving end of the linear module 4 .
[0016] Preferably, the transmission mechanism 6 is a transmission chain, which is rotatably connected to the other end of the base 1. The transmission chain can be a chain, etc., as long as it can transmit the power of the SEW servo drive to the slider 3 so that the slider 3 slides.
[0017] Preferably, a groove is provided on the upper surface of the base 1 in a direction parallel to the guide rod 11 , and the transmission mechanism 6 is arranged in the groove.
[0018] Preferably, a driving gear is installed on the output shaft of the SEW servo driver 2, the lower surface of the transmission chain is engaged with the gear, and the upper surface of the transmission chain is fixedly connected to the slider 3. When the output shaft rotates, the transmission chain is driven to rotate, and the transmission chain further drives the slider 3 to slide along the extension direction of the guide rod 11. The slider 3 thereby drives the folding plate 5 to slide along the extension direction of the guide rod 11 without deviation.
[0019] Preferably, sensors are provided at both ends of the base 1. These sensors are primarily used to position the slider 3. These sensors can be pressure sensors. When the slider 3 moves until it contacts the sensors, the slider stops moving. Furthermore, the sensors can be other types, as long as they ensure that the slider 3 stops at the preset position.
[0020] It should be noted that this device is ultimately controlled by the controller of the YP114 carton filling and sealing machine, and the specific control program is adjusted accordingly according to the working content of the device of the present invention.
[0021] Working principle:
[0022] When the rear folding device is in the unfolded state, the slider (together with the folding plate) stays at the opposite end of the folding station; when the rear folding device is in the folded state, the output shaft of the SEW servo driver starts to rotate and drives the gear transmission installed thereon, the gear drives the transmission chain, and the further transmission chain is transmitted to the slider, thereby realizing that the slider (together with the folding plate) slides to the folding station. When the slider contacts the sensor on the base next to the folding station, the sensor feeds back the signal to the controller, and the controller controls the output shaft of the SEW servo driver to stop rotating, the slider stops, and the folding plate of the rear folding device starts to fold the corresponding folding edge of the bottom of the cigarette box. When the folding work is completed, the controller controls the output shaft of the SEW servo driver to start working again. Specifically, the output shaft rotates in the opposite direction, so that the transmission chain also rotates in the opposite direction, so that the slider is driven to slide to the starting position, that is, the opposite end of the folding station. When the slider contacts the sensor on the base next to the starting position, the controller controls the output shaft of the SEW servo driver to stop rotating, and the slider (together with the folding plate) stops working.
[0023] When folding again, repeat the above steps.
[0024] Compared with the prior art, the beneficial effects of the present invention are:
[0025] The utility model re-arranges the transmission device and the guide device, and fixes the sliding direction of the slider 3 by setting the guide rod 11, effectively preventing the slider 3 (connected to the folding plate 5) from sliding toward a position deviating from the sliding direction;
[0026] In addition, the present invention locates the stop position of the slider 3 (connected to the folding plate 5) by setting a sensor, which can ensure that the slider 3 stops accurately at the preset position;
[0027] At the same time, the present invention adopts a SEW servo driver 2, which has fast response, high precision and good stability. The transmission mechanism 6 driven by the SEW servo driver 2 can accurately stop the slider 3 (connected to the folding plate 5) to a preset position.

[0033] The following examples further illustrate the present invention in detail, but are not intended to limit the present invention. Any modifications or improvements based on the teachings of the present invention fall within the scope of protection of the present invention. Where specific techniques or conditions are not specified in the examples, the techniques or conditions described in the literature in the field or in the product instructions shall be followed.
[0034] Example 1
[0035] like Figure 1 As shown, the utility model provides a cigarette box bottom rear folding device suitable for the YP114 case filling and sealing machine, the rear folding device includes: a base 1, a SEW servo driver 2, a slider 3, a linear module 4, a folding plate 5, and a transmission mechanism 6;
[0036] The base 1 is connected to the guide rods 11 on both sides, and the two sides of the slider 3 are respectively slidably connected to the guide rods 11 on both sides of the base 1;
[0037] The SEW servo driver 2 is fixed to one end of the base 1 , and one end of the transmission mechanism 6 is rotationally connected to the SEW servo driver 2 , and the other end is rotationally connected to the other end of the base 1 .
[0038] Specifically, the transmission mechanism 6 (not shown in the figure) can be a chain, a driving gear (not shown in the figure) is installed on the output shaft of the SEW servo driver 2, and a driven gear (not shown in the figure) is installed at one end of the base 1 opposite to the installation position of the SEW servo driver 2, and the lower surfaces of the two ends of the chain are respectively engaged with the driving gear and the driven gear (not shown in the figure).
[0039] The bottom of the slider 3 is fixedly connected to the upper surface of the chain. The driving gear on the SEW servo driver 2 drives the chain to rotate, thereby driving the slider 3 to slide along the extending direction of the guide rod 11.
[0040] Furthermore, when the output shaft rotates, the chain is driven to rotate, and the chain further drives the slider 3 to slide along the extension direction of the guide rod 11. The slider 3 thereby drives the folding plate 5 to slide along the extension direction of the guide rod 11 without deviation.
[0041] The top of the slider 3 is connected to the fixed end of the linear module 4, and the movable end of the linear module 4 is connected to the folding plate 5, so that the sliding direction of the folding plate 5 on the linear module 4 is perpendicular to the sliding direction of the slider 3. The setting of the linear module 4 is mainly to transport the folding plate 5 in a direction perpendicular to the sliding direction of the slider 3 to finally complete the folding work of the hem.
[0042] The rear folding device further includes a folding plate support frame 7 , which is connected between the folding plate 5 and the moving end of the linear module 4 .
[0043] A groove is provided on the upper surface of the base 1 in a direction parallel to the guide rod 11, and the transmission mechanism 6 is arranged in the groove. The groove can be provided to hide the transmission mechanism 6 for installation, which is beautiful on the one hand and effectively avoids other safety issues or interference with the operation of other components caused by the exposure of the transmission mechanism 6 on the other hand.
[0044] Sensors are provided at both ends of the base 1 , and the sensors are pressure sensors. When the slider 3 moves to contact the sensor, the slider stops moving. This embodiment uses a pressure sensor to achieve positioning of the slider.
[0045] It should be noted that this device is ultimately controlled by the controller of the YP114 carton filling and sealing machine.
[0046] When the rear folding device is in the unfolded state, the slider (together with the folding plate) stays at the opposite end of the folding station; when the rear folding device is in the folded state, the output shaft of the SEW servo driver starts to rotate and drives the gear transmission installed thereon, the gear drives the transmission chain, and the further transmission chain is transmitted to the slider, thereby realizing that the slider (together with the folding plate) slides to the folding station. When the slider contacts the sensor on the base next to the folding station, the sensor feeds back the signal to the controller, and the controller controls the output shaft of the SEW servo driver to stop rotating, the slider stops, and the folding plate of the rear folding device starts to fold the corresponding folding edge of the bottom of the cigarette box. After the folding work is completed, the controller controls the output shaft of the SEW servo driver to start working again, specifically, to make the output shaft rotate in the opposite direction, so that the transmission chain also rotates in the opposite direction, so that the slider is driven to slide to the starting position, that is, the opposite end of the folding station.
[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application.
