Description

Technical Field

[0001] This utility model relates to the technical field of cigarette processing equipment, and in particular to a posture guidance / alignment device during the cigarette pack conveying process. Background Technology

[0002] In the tobacco production process of cutting tobacco into segments, tobacco packs often tilt during transport due to compression deformation or uneven bottom. When the tobacco packs enter the slicing machine tilted, it may cause uneven cutting of tobacco blocks, affecting the subsequent loosening and rehydration effects.

[0003] Meanwhile, as cigarette factories continuously raise their quality requirements, some factories are also becoming increasingly stringent in their requirements for the discharge posture of the slicing machine. However, due to uneven texture of the incoming cigarette packs, the cigarette blocks cut by the slicing machine often fall at a slight angle, resulting in poor posture of the discharged cigarette blocks. Most existing cigarette block guiding devices use a tapered guide plate to guide the cigarette blocks. If the tapered plate is too wide, the guiding effect is poor; if the tapered plate is too narrow, it is easy to cause material blockage and jamming.

[0004] A search revealed Chinese utility model patent CN218859376U, which discloses an electronically controlled guide system for tobacco box loading tracks, comprising: a guide wheel assembly, a drive control device, and a detection device. While this patent can guide tobacco boxes, it has the following drawbacks:

[0005] The smoke box is guided by two sets of symmetrically arranged drive cylinders and guide rails, which simultaneously push it towards the middle of the conveyor belt. However, it occupies a large space and has low space utilization.

[0006] The device has a complex overall structure, and the installation and maintenance process takes a long time, which affects work efficiency.

[0007] To address the shortcomings of the aforementioned guiding devices, such as large footprint and complex overall structure, a compact and efficient attitude guidance / alignment device for the cigarette pack conveying process is proposed, which is the key to solving the above technical problems. Summary of the Invention

[0008] To address the aforementioned problems, this utility model has made improvements and innovations, aiming to provide a posture guidance / alignment device during the cigarette pack conveying process. This device has a compact structure, occupies little space, and is easy to install and maintain. By setting a guiding device, the cylinder, guide block, and guide rail are connected as a whole, thus reducing the size while fulfilling the guiding function.

[0009] Another objective of this invention is to set up a rotating mechanism, with a first rotating mechanism to match the angle changes during the movement of the guide device and a second rotating mechanism to match the angle changes during the movement of the guide plate, so that the guide plate creates a pushing effect on the cigarette pack during its movement, thereby reducing damage to the cigarette pack during the guiding process.

[0010] To solve the above problems and achieve the above-mentioned objectives, this utility model provides a posture guidance / alignment device for the cigarette pack conveying process, which is implemented by adopting the following design structure and the following technical solution:

[0011] A posture correction / alignment device for cigarette pack conveying includes a conveyor belt, a detection device, a solenoid valve, and a control circuit. It also includes adjustment components symmetrically installed on both sides of the conveyor belt. The adjustment components include:

[0021] A connecting plate is located at the end of the guide device and is connected to the connecting seat.

[0022] The connecting seat is set on the guide plate and is rotatably connected to the connecting plate through a rotating shaft perpendicular to the ground, in order to adapt to the angle changes during the movement of the guide plate.

[0023] Preferably, the guiding device includes:

[0024] The cylinder is set in the groove of the guide block and fixed by bolts. The cylinder is connected to the solenoid valve and the external air source through the conduit.

[0025] The guide block has an "H" shaped structure with through holes at its symmetrical ends and guide rails inserted through them. The guide block has a hole in the middle for the cylinder piston to pass through. The guide rails and the cylinder piston are both connected to the connecting plate for guiding the cylinder piston.

[0026] Preferably, the guide plate is perpendicular to the end face of the conveyor belt and has an obtuse angle bend structure. The guide plate is pushed towards the middle of the conveyor belt by the symmetrical guide devices on both sides of the conveyor belt to form a "Y" shaped channel for guiding the cigarette pack.

[0027] Preferably, the first rotating mechanism further includes:

[0028] The first connector is mounted on the fixed frame and has an internal threaded hole in its middle, which is connected to the second connector by an adjusting bolt.

[0029] The second connector is mounted on the rotating seat and corresponds to the first connector. It has an internal threaded hole in its middle. The rotating seat can be finely adjusted within the waist hole range by passing the adjusting bolt through the first connector and the second connector in sequence.

[0030] Preferably, the guide plate includes:

[0031] A hinge is located on one side of the guide plate and is used to hinge the guide plate and the second guard plate.

[0032] The reinforcing frame is a rectangular frame with an obtuse angle bend, located in the middle of the connection surface between the guide plate and the guide device, to increase the structural strength of the guide plate;

[0033] The reinforcing component is an obtuse-angled triangular structure that matches the guide plate and is symmetrically arranged at the corners of the reinforcing frame.

[0034] Preferably, the second guard plate has a rectangular through hole to provide the space required for the cylinder piston angle to change during the guiding process.

[0035] Preferably, the detection device is an infrared proximity switch, which is installed on the first protective plate to detect the dalai of the cigarette pack in advance, so that the adjustment device can start running.

[0036] The cylinder, solenoid valve, and detection device are all electrically connected to the control circuit.

[0037] Preferably, the adjustment component further includes:

[0038] The housing is fitted onto the adjustment assembly. The size of the housing is sufficient for the guide device to move within the housing. It is connected to the mounting bracket by bolts. Several ventilation holes are opened on the side wall of the housing for heat dissipation.

[0039] The working principle is as follows: The above-described cigarette pack conveying posture correction / alignment device, through the symmetrical arrangement of adjustment components on both sides of the conveyor belt 5, and the installation bracket 1, rotating device 2, and guiding device 3, and by placing cylinder 31 within the groove of guide block 32, with connecting plate 221 simultaneously connecting the piston of cylinder 21 and guide rail 321, achieves a more compact structure and reduces the overall size of the adjustment components while providing guidance. A guide plate 4 with an obtuse angle bend is provided, with one side of the guide plate 4 hinged to the second guard plate 52. Under the action of the guiding device 3, the guide plate 4 is pushed, forming a "Y-shaped" channel between the symmetrically arranged guide plates 4. At this time, the end face of the guide plate 4 is parallel to the second guard plate 52, and the reciprocating motion of the cylinder 31 guides the moving cigarette pack. During the cigarette pack alignment process, the axial movement of the guide plate 4 creates a pushing effect on the cigarette pack, reducing the collision between the cigarette pack and the guide plate 4 and preventing damage to the cigarette pack. A rotating component 213 is provided between the guide block 32 and the rotating seat 212, allowing the rotating component... 213 rotates relative to the rotating seat 212 to adapt to the angle change of the guide device 3 during the guiding process; by setting a connecting seat 222 on the guide plate 4 and a connecting plate 2121 at the piston end of the cylinder 31, the connecting plate 221 is connected by a rotating shaft perpendicular to the ground on the connecting seat 222 to adapt to the angle change of the guide plate 4 during the guiding process; by setting a detection device 6, the first infrared detector 61 and the second infrared detector 62 are respectively set on the second guard plate 52 on both sides of the conveyor belt 5 and are arranged in a staggered manner. If the first infrared detector 61 and the second infrared detector 62 detect the cigarette pack at the same time, it means that the cigarette pack is crooked. The guide device is started by the control circuit. If the first infrared detector 61 and the second infrared detector 62 do not detect the cigarette pack at the same time, it means that the cigarette pack is in the correct posture and does not need to be straightened. At this time, the cylinder 31 is in the retracted state, so that the side of the guide plate 4 that is farther away from the hinge 321 approaches the second guard plate 52, forming a wider channel between the symmetrical guide plates 4, so that the cigarette pack is conveyed away along the conveyor belt 5.

[0040] During the process of guiding the slicing of the tobacco block, since the tobacco block is continuous, the first infrared detector 61 and the second infrared detector 62 simultaneously detect the tobacco block signal, causing the control circuit to control the guiding device to continuously guide the slicing of the tobacco block.

[0041] The above describes the operation through the cooperation of the control circuit and the detection device 6. The control and guidance device 3 is a conventional technology in this field and does not involve any improvement in computer software control. Only the operation function is described here, and the specific principle and method will not be elaborated.

[0042] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0043] 1. This utility model sets up a guide device to place the cylinder in the groove of the guide block, so that the cylinder and the guide block are connected as a whole, and the cylinder piston is guided by the guide rails symmetrically arranged in the guide block.

[0044] 2. This utility model uses an obtuse-angled guide plate to connect one side of the guide plate to the second guard plate. Under the action of the guiding device and the rotating mechanism, a "Y-shaped" channel is formed between the guide plates to guide the cigarette pack.

[0045] 3. This utility model sets up a rotating mechanism to make the guide block rotate relative to the mounting bracket and the connecting plate rotate relative to the connecting seat, thereby adapting to the angle changes caused by the axial movement of the guide plate during the guiding process, so that the guide plates form a channel with a large inlet end and a small outlet end.

[0046] 4. This utility model increases the strength of the mounting bracket by setting up an installation bracket and a crossbeam below the conveyor belt.

[0047] 5. This utility model provides a waist-shaped hole on the rotating seat and adjusts the guide device by adjusting the bolt in conjunction with the first and second connecting parts to make the guide plate end face parallel to the second guard plate, thereby achieving a better guiding effect.

[0048] 6. By setting up a housing, which is fitted onto the adjustment device, this utility model avoids the impact of smoke and dust on the cylinder and rotating mechanism during operation, thus ensuring the stability of the guiding operation. Attached Figure Description

[0066] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0067] Example 1

[0068] like Figures 1 to 6The illustrated cigarette pack conveying posture guidance / alignment device includes a conveyor belt 5, a detection device 6, a solenoid valve, and a control circuit. It also includes adjustment components symmetrically installed on both sides of the conveyor belt 5. The adjustment components include:

[0069] Mounting bracket 1, with its end connected to the first guard plate 51 and its middle connected to the rotating mechanism 2;

[0070] The rotating mechanism 2 includes a first rotating mechanism 21 and a second rotating mechanism 22. The first rotating mechanism 21 is located at the bottom of the guide device 3 and is connected to the mounting bracket 1. The second rotating mechanism 22 is located at the working end of the guide device 3 and is connected to the guide plate 4. The first rotating mechanism 21 is used to match the angle changes of the guide device 3 during its movement, and the second rotating mechanism 22 is used to match the angle changes of the guide plate 4 during its movement.

[0071] Guide device 3, the guide device 3 is equipped with a cylinder 31 inside, the piston of the cylinder 31 is connected to the second rotating mechanism 22;

[0072] Guide plate 4, the middle of the end face of guide plate 4 is connected to the second rotating mechanism 22, and one side of guide plate 4 is hinged to the second guard plate 52. Through the cooperation between rotating mechanism 2 and guide device 3, the skewed cigarette packs on the conveyor belt 3 are guided by the symmetrically arranged guide plate 4.

[0073] Furthermore, the first rotating mechanism 21 includes:

[0074] The fixed base 211 is fixedly connected to the mounting bracket 1. The end face of the fixed base 2111 is provided with a first connecting piece 2111 and internal threaded holes are provided at the four vertices.

[0075] Specifically, the lower end of the fixing base 211 is provided with a trapezoidal protrusion to form an "L-shaped" structure, which is used to improve the stability at the connection position.

[0076] The rotating base 212 has a connecting groove 2121 on one side and a second connecting piece 2122 on the other side. It has waist holes at its four vertices and is connected to the fixed base 211 by bolts passing through the waist holes.

[0077] Rotating component 213, the upper end of rotating component 213 is connected to the bottom of guide device 3, the lower end is sleeved in connecting groove 2121 and rotatably connected to connecting groove 2121, and is fixed by bolts passing through fixed seat 211 and rotating seat 212 in sequence, so as to adapt to the angle change during the movement of guide device 3;

[0078] Specifically, because the guide plate 4 has an obtuse angled bend structure and one side of the guide plate 4 is hinged to the second guard plate 52, the movement of the guide plate 4 is a rotational movement around the hinge 41. This causes the guide device 3 to change angles during the process of pushing the guide plate 4. The rotational connection between the rotating seat 212 and the rotating component 213 is used to adapt to the angle changes during the guiding process.

[0079] The first connector 2111 and the second connector 2122 are each provided with corresponding internal thread holes. The horizontal position of the rotating seat 212 is finely adjusted by passing the adjusting bolt through the first connector 2111 and the second connector 2122 in sequence.

[0080] In this utility model, the guide plates 4, which need to be symmetrically arranged, form a "Y" shaped channel on the conveyor belt 5 after being pushed. At this time, the end face of the guide plate 4 that is farther from the hinge needs to be parallel to the second guard plate 52 to achieve a better guiding effect. The operator adjusts the rotating seat 212 within the range of the waist hole of the rotating seat 212 to adjust the distance between the guide device 3 and the second guard plate 52, thereby adjusting the size of the opening of the guide plate 4 that is farther from the hinge to ensure the guiding effect of the cigarette pack.

[0081] Furthermore, the second rotating mechanism 22 includes:

[0082] Connecting plate 221 is disposed at the end of guide device 3 and connected to connecting seat 222;

[0083] Connecting seat 222 is set on guide plate 4 and is rotatably connected to connecting plate 221 through a rotation axis perpendicular to the ground direction, so as to adapt to the angle change of guide plate 4 during the movement process.

[0084] In this utility model, since the movement of the guide plate 4 is a rotation around the hinge 41, an angle change occurs during the process of the cylinder 31 pushing the guide plate 4. It is connected to the connecting seat 222 through the connecting plate 221. Under the action of the rotation axis of the connecting seat 222 perpendicular to the ground, the connecting plate 221 moves around the rotation axis to adapt to the angle change during the guiding process.

[0085] Furthermore, the guiding device 3 includes:

[0086] Cylinder 31 is set in the groove of guide block 32 and fixed by bolts. Cylinder 31 is connected to solenoid valve and external air source through conduit.

[0087] Guide block 32 has an "H" shaped structure. It has through holes at both ends and guide rails 321 are fitted through it. The guide block 32 has a hole in the middle for the piston of cylinder 31 to pass through. The guide rails 321 and the piston of cylinder 31 are both connected to the connecting plate 221 for guiding the piston of cylinder 31.

[0088] In this utility model, such as Figure 6 As shown, by setting the cylinder 31 in the groove of the guide block 32 and setting the guide rails 321 at both ends of the guide block 32, not only can the cylinder 31 be limited and guided by the guide rails 321 during its movement, but the overall volume of the guide device 3 is also reduced, the space occupancy rate is reduced, and the overall adjustment device is more compact, making it easier to install and move.

[0089] Furthermore, the guide plate 4 is perpendicular to the end face of the conveyor belt 5, and the guide plate 4 has an obtuse angle bend structure. The guide plate 4 is pushed towards the middle of the conveyor belt 5 by the symmetrical guide devices 3 on both sides of the conveyor belt 5 to form a "Y" shaped channel for guiding the cigarette pack.

[0090] In this utility model, such as Figure 2 As shown, the guide device 3 simultaneously pushes the guide plate 4, causing the guide plate 4 to form a "Y" shaped channel on the conveyor belt 5. The inlet end is large and the opening end is small, which facilitates the correction of the tilted cigarette pack. When the cigarette pack is in the correct posture, the guide plate 4 is in the retracted state, and a wider channel is formed between the symmetrical guide plates 4, allowing the cigarette pack to pass through smoothly.

[0091] Specifically, the guide plate 4 is 20mm-40mm higher than the end face of the conveyor belt 5.

[0092] Before using the above-described posture guidance / alignment device for cigarette pack conveying, the operator first connects and fixes the mounting bracket 1 symmetrically on both sides of the conveyor belt 5 using bolts. The fixing seat 211 is welded to the mounting bracket 1. Bolts are then passed through the waist holes at the four vertices of the rotating seat 212 and connected to the internal threaded holes at the four vertices of the fixing seat 211. Adjusting bolts are then passed sequentially through the first connecting piece 2111 and the second connecting piece 2122, and secured with nuts. Figure 4 As shown; then, use bolts to fix the rotating part 213 to the lower end of the guide block 32, insert the working end of the cylinder 31 into the groove of the guide block 32, so that the piston of the cylinder 31 passes through the pre-set through hole in the middle of the guide block 32, and then use bolts to connect the cylinder 31 and the guide block 32 into a whole. After the guide rail 321 passes through the through hole in the middle of the symmetrical ends of the guide block 32, connect the piston of the cylinder 31 and the guide rail 321 to the end face of the connecting plate 221; put the lower end of the rotating part 213 into the connecting groove 2121, and use bolts to pass through the fixed seat 211 and the rotating seat 212 from bottom to top and connect them to the rotating part 213, and fix the rotating part 213 in the vertical direction. At this time, the rotating part 213 drives the guide device 3 to rotate relative to the rotating seat 212, as shown. Figure 6As shown; the second guard plate 52 is connected to the first guard plate 51. A rectangular hole is opened at the corresponding position of the second guard plate 52 and the guide device 3. The guide plate 4 is connected to the second guard plate 52 using a hinge 41. At this time, the included angle of the guide plate 4 faces the guide device 3. The middle of the end face of the guide plate 4, which is farther from the hinge 31, is connected to the connecting seat 222 by bolts. At this time, the rotation shaft set on the connecting seat 222 is set perpendicular to the ground. The connecting plate 221 and the connecting seat 222 are connected by the rotation shaft. At this time, the size of the rectangular hole opened on the second guard plate 52 is larger than the range of motion of the guide device 3 during the guiding process. A first infrared detector 61 and a second infrared detector 62 are respectively set on the second guard plate 52 on both sides of the conveyor belt 5. The first infrared detector 61 and the second infrared detector 62 are arranged in a staggered manner, as shown. Figure 2 As shown, the cylinder 31 is connected to the solenoid valve and the external air source using a conduit, and the solenoid valve, the first infrared detector 61 and the second infrared detector 62 are connected to the control circuit. Thus, the assembly of the adjustment device is completed.

[0093] During use, the cigarette packs are conveyed to the detection device 6 by the conveyor belt 5. When the cigarette packs are tilted, the first detection device 61 and the second detection device 62 simultaneously detect the signal. The control circuit controls the solenoid valve to vent air to the cylinder 31, causing the cylinder 31 to push the guide plate 4. Under the action of the guide block 32 and the guide rail 321, the piston of the cylinder 31 pushes in a fixed direction. Because one side of the guide plate 4 is connected to the second guard plate 52 through the hinge 41, the movement of the guide plate 4 is a rotation around the hinge 41. This causes the guide device 3 to experience an angle change during the process of pushing the guide plate 4. The relative rotation between the rotating seat 212 and the rotating part 213 adapts to the angle change during the guiding process. The action of the rotation axis between the connecting plate 221 and the connecting seat 222 causes the connecting plate 221 to move around the rotation axis, thus adapting to the angle change during the guiding process. This allows the symmetrically arranged guide plates 4 to form a "Y" shaped channel on the conveyor belt 5, with the inlet end being larger and the opening end being smaller. Figure 2 As shown, the cigarette pack is guided by the reciprocating motion of the cylinder 31. During the guidance process, the rotational motion of the guide plate 4 creates a pushing effect on the cigarette pack, reducing the occurrence of collisions between the cigarette pack and the guide plate 4 during the guidance process, which could cause damage to the cigarette pack.

[0094] When the cigarette pack is in the correct position and does not require alignment, if the first infrared detector 61 and the second infrared detector 62 do not detect the cigarette pack at the same time, it means that the cigarette pack is in the correct posture and does not require alignment. At this time, the cylinder 31 is in the retracted state, so that the side of the guide plate 4 that is farther from the hinge 321 approaches the second guard plate 52, forming a wider channel between the symmetrical guide plates 4, so that the cigarette pack is conveyed away along the conveyor belt 5.

[0095] Example 2

[0096] This embodiment 2 is the same as embodiment 1, except that, as Figure 4 As shown, the guide plate 4 also includes a reinforcing frame 42 and a reinforcing member. The reinforcing frame 42 is a rectangular frame with an obtuse angle bend and is located in the middle of the connection surface between the guide plate 4 and the guide device 3 to increase the structural strength of the guide plate 4. The reinforcing member is an obtuse triangular structure that matches the guide plate 4 and is symmetrically arranged at the bend of the reinforcing frame 42.

[0097] In this utility model, by setting a reinforcing frame 42 and a reinforcing member on the guide plate 4, the reinforcing frame 42 ensures the overall stability of the end face of the guide plate during the process of guiding and moving the cigarette pack, and the triangular structure of the reinforcing member ensures the stability at the obtuse angle bend.

[0098] Furthermore, the second guard plate 52 is connected to the first guard plate 51 by bolts, and has a rectangular through hole to provide the space required for the piston angle of the cylinder 31 to change during the guiding process.

[0099] Example 3

[0100] This embodiment 3 is the same as embodiment 1, except that, as Figure 7 As shown, the mounting bracket 1 also includes a fixing beam 11, which is located below the conveyor belt 5 and connected to the symmetrically arranged mounting bracket 1 to increase the fixing strength.

[0101] In this invention, by setting a fixed beam 11 below the conveyor belt 5 and providing traction towards the middle of the conveyor belt 5 between the mounting brackets 1, the reverse force during the process of the guide device 3 pushing the cigarette pack is offset, thus ensuring the stability of the overall structure.

[0102] Furthermore, the detection device 6 includes a first infrared detector 61 and a second infrared detector 62, which are respectively installed on the second guard plates 52 on both sides of the conveyor belt 5 and are arranged in a staggered manner. This is used to detect the posture of the tobacco pack when it arrives in advance, so that the adjustment device can start running.

[0103] The cylinder 31, solenoid valve, and detection device 6 are all electrically connected to the control circuit. After the detection device 6 detects that the cigarette pack is misaligned, the control circuit controls the solenoid valve to open and close the air passage, causing the cylinder 31 to reciprocate.

[0104] In this invention, the staggered arrangement of the first infrared detector 61 and the second infrared detector 62 means that if both detectors detect the cigarette pack simultaneously, it indicates that the cigarette pack is crooked, and the guiding device is activated by the control circuit. If the first infrared detector 61 and the second infrared detector 62 do not detect the cigarette pack simultaneously, it means that the cigarette pack is in the correct posture and no guidance is needed. At this time, the cylinder 31 is in the retracted state, so that the cigarette pack is conveyed away along the conveyor belt 5.

[0105] Specifically, the distance between the detection extension lines of the first infrared detector 61 and the second infrared detector 62 is 10mm-30mm.

[0106] Example 4

[0107] This embodiment 4 is the same as embodiment 1, except that, as Figure 8-9 As shown, the adjustment assembly also includes a housing 7, which is fitted onto the adjustment assembly. The size of the housing 7 is such that the guide device 3 can move within the housing 7. It is connected to the mounting bracket 1 by bolts. Several ventilation holes are opened on the side wall of the housing 7 for heat dissipation.

[0108] In this invention, by providing a housing 7, the cigarette pack debris and dust are prevented from affecting the guiding device and rotating mechanism, thus ensuring the effectiveness of the guiding operation.

[0109] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
