Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigar production devices, in particular to a cigarette box pushing mechanism for conveying cigars and a reversing conveying device containing the mechanism. Background Art
[0002] In the field of tobacco machinery, the cigarette box conveying channel is an important part of the packaging machine. It has the functions of storing and diverting cigarette boxes to ensure that the cigarette boxes are continuously supplied to the packaging machine. In particular, in the packaging process of cigars, the cigarette boxes output by the small box transparent paper packaging machine need to be conveyed to the downstream strip box packaging machine for packaging.
[0003] Since the packaging process of the downstream strip packaging is a unique three-three-four arrangement packaging, it is necessary to perform a horizontal reversal operation on the cigarette boxes in a conveying channel to meet the process requirements. During the cigarette box reversal process, the cigarette box needs to be stationary relative to the steering mechanism to prevent the cigarette box from being centrifugally dislodged during the horizontal steering. However, the reversing cigarette box is transported from the steering mechanism to the linear conveyor belt, and a push rod needs to be set to push the cigarette box of the steering mechanism horizontally to the linear conveyor belt.
[0004] The traditional push rod is a cylinder transmission type. Since the cylinder requires pneumatic and piston action, the response speed is slow, which reduces the efficiency of cigarette box transportation. In addition, the traditional cylinder push rod requires two cylinders or two-way cylinders respectively in the process of pushing the cigarette box into and out of the reversing conveying device. The transmission of the cylinder has high requirements on the accuracy of air pressure control, because the distance between the pushing end of the cigarette box to be pushed in and the pushing end of the cigarette box to be pushed out remains unchanged; however, the current technology has not achieved high-precision air pressure control of the cylinder piston, resulting in low operational coordination between pushing in and pushing out the cigarette box, so that there is a slight misalignment between the two ends of the cylinder push rod or the push rods of the two cylinders, resulting in the two ends of the cylinder or the two cylinders cannot be accurately located at the pushing end of the cigarette box to be pushed in and the pushing end of the cigarette box to be pushed out, and the cigarette boxes are often scratched and pressed, resulting in the problem of reduced quality of cigar box packaging. Utility Model Content
[0005] The purpose of the utility model is to provide a cigarette box pushing mechanism for conveying cigars, which includes: a first servo motor, a connecting rod mechanism, a pushing assembly and a crank structure; one end of the connecting rod mechanism is a fixed-axis rotating end, which can rotate around the fixed axis; the other end of the connecting rod mechanism is a movable end, which can be detachably fixedly connected to the pushing assembly; one end of the crank structure is drivingly connected to the first servo motor; the other end of the crank structure is transmission-connected to the connecting rod mechanism, which can drive the movable end of the connecting rod mechanism to slide in a straight line, thereby driving the two ends of the pushing assembly to push the cigarette box synchronously along a straight line.
[0006] The solution described in the utility model is to provide a first servo motor, which is driven and connected to the crank structure and can drive the crank structure to move; the other end of the crank structure is driven and connected to the connecting rod mechanism and can drive the movable end of the connecting mechanism to slide linearly. Since the rotating arm of the crank structure is a rigid part and the swinging arm of the connecting rod mechanism is also a rigid part, compared with the traditional cylinder air pressure control, there is no inflation time, so it can respond to the drive more quickly, thereby shortening the pushing time; and, the rotating arm and the swinging arm of the crank structure and the connecting rod mechanism of the utility model are both rigid parts with fixed lengths, and the displacement deviation in the transmission process is small, and the servo motor is used to accurately control the rotation angle and the rotation speed, so that the two ends of the pushing assembly can be more accurately positioned at the pushing end of the cigarette box to be pushed in and the pushing end of the cigarette box to be pushed out, respectively, avoiding the cigarette box being scratched and pressed due to the inability to accurately position the push rod, thereby improving the quality of cigar production and the efficiency of transportation.
[0007] Preferably, the cigarette box pushing mechanism for conveying cigars described in the utility model, the connecting rod mechanism includes: a first swing arm, a second swing arm, a third swing arm and a linear slide rail; one end of the first swing arm is a fixed-axis rotating end, and is horizontally rotatably connected to the base through a rotating shaft, one end of the second swing arm is hinged to the middle part of the first swing arm, and the other end of the second swing arm is horizontally rotatably connected to the crank structure; one end of the third swing arm is hinged to the other end of the first swing arm, and the other end of the third swing arm is slidably connected to the linear slide rail through a sliding member, thereby forming the movable end; the track extension direction of the linear slide rail is parallel to the straight line formed by the cigarette box pushing end and the cigarette box pushing end.
[0008] As a preferred solution of the utility model, by setting the connecting rod mechanism to include three swing arms, the first swing arm cooperates with the crank structure to rotate, which can drive the second swing arm to rotate around the fixed axis, and the third swing arm is hinged to one end of the second swing arm, thereby driving the movable end formed by the third swing arm to slide on the linear slide rail, and since the push assembly is detachably fixed to the movable end formed by the third swing arm, it follows the movable end to move on the linear slide rail; by setting the track extension direction of the linear slide rail to be parallel to the straight line formed by the cigarette box input end and the cigarette box output end, by respectively arranging the two ends of the push assembly at the cigarette box input end and the cigarette box output end, the push assembly is synchronously moved toward the straight line formed by the input end and the cigarette box output end, and then the cigarette box is synchronously pushed toward the cigarette box input end and pushed out toward the cigarette box output end, so that the driving force of the first servo motor is relatively continuously transmitted to the push assembly through the crank structure and the connecting rod mechanism. Through the above design, the continuous inertia of the power transmission is better and the energy consumption is smaller, which further enhances the performance of the mechanism.
[0009] Preferably, the cigarette box pushing mechanism for conveying cigars described in the utility model, the pushing assembly includes a push rod slide shaft, a pushing piece and a pushing piece; the push rod slide shaft is supported above the base by a support arm; the support arm is provided with a sliding hole for the push rod slide shaft to pass through; the push rod slide shaft is detachably fixedly connected to the movable end by a first fixing piece, and then moves back and forth axially with the movable end; the push rod slide shaft, the pushing piece and the pushing piece are respectively fixed to the two ends of the push rod slide shaft.
[0010] As a preferred solution of the utility model, the push assembly is configured to include a push rod slide shaft, an ejection member and a propulsion member, and then a support arm and a sliding hole are provided to cooperate with the reciprocating movement of the push rod slide shaft, so that the push rod slide shaft can stably reciprocate along a straight line driven by the movable end. Since the push rod slide shaft is a rigid member and cooperates with the support arm and the sliding hole for stable support, there is no misalignment between the ejection member and the propulsion member during the process of synchronously pushing and ejecting the cigarette box, and the positioning error is also small, thereby reducing the probability of damage to the cigarette box due to misalignment and further improving the production quality.
[0011] Preferably, in the cigarette box pushing mechanism for conveying cigars described in the utility model, the sliding member comprises: a connecting rod and a bearing; one end of the connecting rod is fixedly connected to the push rod sliding shaft and is hinged to the movable end through a connecting member, and the other end of the connecting rod is axially connected to the bearing; the bearing is arranged in the track of the linear slide rail, and can move along the linear slide rail.
[0012] As a preferred solution of the utility model, by setting the sliding part as a connecting rod and a bearing, the articulation of the third swing arm is facilitated, and it can also be fixedly connected with the push rod sliding shaft. The push rod sliding shaft can be synchronously driven by the third swing arm to slide along the linear slide rail, thereby reducing the influence of the mechanical connection between the third swing arm and the connecting rod, and between the connecting rod and the push rod sliding shaft on the transmission force, enhancing the coordination of the structure, reducing mechanical wear, and extending the service life.
[0013] Preferably, in the cigarette box pushing mechanism for conveying cigars described in the utility model, the upper part of the pushing member is detachably fixed to the push rod sliding shaft by a second fixing member, and the lower part of the pushing member includes an integrally formed oblique arm and a first pushing member; the oblique arm is connected to the middle part of the first pushing member; the first pushing member is rectangular, and the long side is perpendicular to the pushing direction of the cigarette box.
[0014] As a preferred solution of the utility model, the second fixing member can be fixed to the end of the push rod sliding shaft, and the lower part of the ejection member can be detachably connected to the second fixing member, so as to facilitate the replacement of damaged oblique arm and first pushing member; the oblique arm and the first pushing member are integrally formed, and the oblique arm is connected to the middle part of the first pushing member, and the driving force can be evenly transmitted to the first pushing member through the oblique arm, so that the forces on both sides of the length direction of the first pushing member are equal, thereby avoiding the tilt of the first pushing member causing the pushed cigarette box to tilt; the long side of the rectangular first pushing member is perpendicular to the pushing direction of the cigarette box, thereby increasing the force area and the effective pushing force, further avoiding the cigarette box from being pushed crookedly and reducing energy consumption, thereby further improving the production quality and production efficiency.
[0015] Preferably, in the cigarette box pushing mechanism for conveying cigars described in the utility model, the pushing member includes a third fixing member, a second pushing member, and a one-way limiting member; the upper part of the third fixing member is detachably fixed to the push rod sliding shaft; two of the second pushing members are arranged in parallel and are respectively axially connected to the two sides of the third fixing member, and can be vertically rotated around the third fixing member, and thus can be lifted upward; the one-way limiting member is used to press against one side of the second pushing member, thereby limiting the rotation of the second pushing member in the pushing direction of the cigarette box.
[0016] As a preferred solution of the utility model, two second pushing members are provided for pushing the cigarette box into the conveying channel. Since the push rod sliding shaft moves back and forth, the pushing member needs to be reset before pushing the cigarette box again. By arranging the two second pushing members in parallel and connecting them to the third fixing member respectively, they can be vertically rotated around the third fixing member and then lifted upward. In the process of moving and resetting in the direction opposite to the pushing direction, the second pushing member is vertically rotated and lifted by the upward force of the cigarette box, thereby preventing the second pushing member from scratching the cigarette box or bringing out the cigarette box that has been pushed into place during the resetting process, thereby improving the accuracy of the cigarette box conveying position, reducing cigarette box damage, and further improving production quality.
[0017] Preferably, in the cigarette box pushing mechanism for conveying cigars described in the utility model, a side of the second pushing member facing away from the cigarette box is provided with a guide ridge inclined in the pushing direction of the cigarette box.
[0018] As a preferred solution of the utility model, since the second pushing member needs to move away from the cigarette box for resetting, a guide ridge is provided on the side of the second pushing member facing away from the cigarette box, and the inclination direction of the guide ridge is in the direction of the cigarette box propulsion, so that the inclination direction of the guide ridge is opposite to the resetting movement direction of the second pushing member, so that the force surface of the second pushing member during the resetting movement away from the cigarette box is perpendicular to the direction of the combined force of the upward resistance force and the resetting force of the cigarette box, thereby increasing the lifting force on the second pushing member, and the contact area is smaller, which further reduces the scratching effect on the cigarette box due to contact with the cigarette box, reduces the probability of cigarette box damage, and further improves production quality.
[0019] In order to achieve the above-mentioned purpose and meet the requirement of reversing the cigarette boxes in a conveying channel in the horizontal direction, the utility model also provides a reversing conveying device, comprising the above-mentioned cigarette box pushing mechanism for conveying cigars, and also comprising: a second servo motor and a turntable; the second servo motor is drivingly connected to the bottom of the turntable; the turntable is arranged below the cigarette box pushing mechanism; the turntable is provided with a pushing station and a pushing station; the pushing station and the pushing station respectively correspond to the two ends of the pushing assembly; the turntable can rotate horizontally from the pushing station to the pushing station under the driving control of the second servo motor.
[0020] The reversing conveying device of the utility model is provided with a second servo motor and a turntable. The turntable is driven and controlled by the second servo motor, which can not only drive the turntable to rotate horizontally at high speed, but also can control the rotation speed and stop time of the turntable so that the turntable can stop accurately at the positions corresponding to the pushing station and the pushing station respectively, so that the cigarette boxes can be quickly and accurately reversed, thereby meeting the three-three-four arrangement packaging requirements and accurately and quickly conveying the cigarette boxes, thereby improving the cigar production efficiency and the effective operation rate of the equipment, thereby improving the production benefits.
[0021] Preferably, in the reversing conveying device described in the utility model, the turntable is provided with four limit blocks in a circumferential array; cigarette boxes are placed between two adjacent limit blocks; and the limit blocks are detachably fixed on the top of the turntable.
[0022] As a preferred solution of the utility model, four limit blocks in a circumferential array are arranged on the turntable, and a cigarette box is placed between two adjacent limit blocks. The turntable rotates the empty space between two adjacent limit blocks to face the cigarette box to be pushed in, so that the empty space between the two adjacent limit blocks forms a pushing station, and the cigarette box is pushed into the pushing station by the pushing mechanism. Under the driving control of the second servo motor, the cigarette box carried by the turntable to the pushing station is horizontally rotated by 90 degrees and then stopped. The pushing station pushes the cigarette box again, and synchronously, the cigarette box limited between the two adjacent limit blocks is carried to the pushing station, and the turntable After continuing to rotate horizontally in the same direction for 90 degrees, it stops again, and the pushing station pushes the cigarette box in again, and the cigarette box is pushed out of the pushing station. The cigarette box is transported after being turned 180 degrees, thus realizing the rapid turning and 180-degree transportation of the cigarette box. In addition, the limit blocks with precise dimensions cooperate with the rotary servo during the synchronous horizontal rotation of the turntable to make the switching more precise, avoiding the shaking of the cigarette box during the switching process, thereby reducing the displacement or misalignment of the cigarette box during the turning and transportation, and then reducing the occurrence of scratches and damage to the cigarette box, reducing the waste of raw materials, improving production quality, reducing costs, and further improving production efficiency.
[0023] Preferably, the reversing conveying device described in the utility model further includes a control system; the control system is used to control the first servo motor and the second servo motor to operate in coordination with each other.
[0024] As a preferred solution of the utility model, by setting up a control system, the start and stop time nodes, speed, etc. of the first servo motor and the second servo motor can be set in the servo system to realize the control of the first servo motor and the second servo motor to cooperate with each other. For example, the second servo motor is controlled to make the turntable rotate horizontally, and the first servo motor is synchronously controlled to stop, and then the pushing mechanism is not operated; the second servo motor is controlled to stop the turntable, and then the first servo motor is synchronously controlled to run, and then the pushing mechanism is cooperated to push the cigarette box, so that the rotation of the turntable and the pushing of the pushing mechanism can be highly coordinated without mutual influence, thereby further improving the production efficiency and the effective operation rate of the equipment.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0026] 1. Compared with the traditional cylinder air pressure control, there is no inflation time, so it can respond to the drive more quickly, thereby shortening the push time; the rotating arm and the swing arm of the crank structure and the connecting rod mechanism are rigid parts with fixed lengths, and the displacement deviation during the transmission process is small. In combination with the servo motor to accurately control the rotation angle and rotation speed, the two ends of the push assembly can be more accurately positioned at the pushing and pushing positions of the cigarette box, respectively, avoiding the scratching and pressing of the cigarette box caused by the inaccurate positioning of the push rod, thereby improving the quality of cigar production and the efficiency of transportation;
[0027] 2. The steering conveying device controls the turntable by driving the second servo motor, so that the turntable can stop accurately at the positions of the pushing station and the pushing station respectively, so that the cigarette boxes can be quickly and accurately changed, thereby meeting the three-three-four arrangement packaging requirements while also being able to accurately and quickly convey the cigarette boxes, thereby improving the cigar production efficiency and the effective operation rate of the equipment, thereby improving the production benefits.

[0034] The utility model is described in detail below in conjunction with the accompanying drawings.
[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0036] Example 1
[0037] like Figure 1 As shown, the present embodiment discloses a cigarette box pushing mechanism for conveying cigars, comprising: a first servo motor 1, a connecting rod mechanism 2, a pushing assembly 3 and a crank structure 4; one end of the connecting rod mechanism 2 is a fixed-axis rotating end 21, which can rotate around a fixed axis; the other end of the connecting rod mechanism 2 is a movable end 22, which can be detachably fixedly connected to the pushing assembly 3; one end of the crank structure 4 is drivingly connected to the first servo motor 1; the other end of the crank structure 4 is drivingly connected to the connecting rod mechanism 2, which can drive the movable end 22 of the connecting rod mechanism 2 to slide in a straight line, thereby driving the two ends of the pushing assembly 3 to synchronously push the cigarette box 0 along a straight line.
[0038] The connecting rod mechanism 2 is understood to be able to cooperate with the crank structure 4 to drive the movable end 22 to slide linearly, thereby driving the two ends of the pushing assembly 3 to push the cigarette box 0 synchronously along a straight line. Figure 2 As shown, the connecting rod mechanism 2 includes: a first swing arm 23, a second swing arm 24, a third swing arm 25 and a linear slide rail 26; one end of the first swing arm 23 is a fixed-axis rotating end 21, and is horizontally rotatably connected to the base 5 through a rotating shaft; one end of the second swing arm 24 is hinged to the middle part of the first swing arm 23, and the other end of the second swing arm 24 is horizontally rotatably connected to the crank structure 4; one end of the third swing arm 25 is hinged to the other end of the first swing arm 23, and the other end of the third swing arm 25 is slidably connected to the linear slide rail 26 through a sliding member 27 to form a movable end 22; the track extension direction of the linear slide rail 26 is parallel to the straight line formed by the cigarette box 0 push-in end and the cigarette box 0 push-out end.
[0039] It should be noted that the crank structure 4 is understood as having one end drivingly connected to the first drive motor and the other end rotatably connected to the first swing arm 23, so that it can drive the first swing arm 23 to swing horizontally under the drive of the first drive motor. For example, the crank structure 4 is a transmission eccentric disk, and the first servo motor 1 transmits power to the connecting rod mechanism 2 through the transmission eccentric disk installed on its rotating shaft, thereby driving the push rod sliding shaft 31 to move; according to the basic transmission principle of the connecting rod mechanism 2, the horizontal swing of the first swing arm 23 can drive the second swing arm 24 and the third swing arm 25 to move in linkage, one end of the second swing arm 24 rotates on a fixed axis, and the other end is hinged to the third swing arm 25, so that the movable end 22 of the third swing arm 25 can move back and forth on a linear track through the sliding member 27.
[0040] In this embodiment, the pushing component 3 is understood to be a component that can push the cigarette box 0 at both ends, for example, a rod in the middle and push plates fixed at both ends, so as to push and push out the cigarette box 0; specifically, Figure 1 and Figure 2As shown, the push assembly 3 includes a push rod slide shaft 31, an ejection member 32 and a propulsion member 33; the push rod slide shaft 31 is supported on the base 5 by a support arm 51; above; the support arm 51 is provided with a slide hole 511 for the push rod slide shaft 31 to pass through; the middle part of the push rod slide shaft 31 is detachably fixedly connected to the movable end 22 by a first fixing member 311, and then moves back and forth axially with the movable end 22; the ejection member 32 and the propulsion member 33 of the push rod slide shaft 31 are respectively fixed at the two ends of the push rod slide shaft 31, wherein the "axial direction" is understood to be the axial direction of the push rod slide shaft 31.
[0041] In this embodiment, the sliding member 27 is understood to be a component that can slide along the track on the linear slide rail 26, such as a slider or a slide rod. Specifically, the sliding member 27 includes: a connecting rod 271 and a bearing 272; one end of the connecting rod 271 is fixedly connected to the push rod slide shaft 31, and is hinged to the movable end 22 through a connecting member 273, and the other end of the connecting rod 271 is axially connected to the bearing 272; the bearing 272 is arranged in the track of the linear slide rail 26, and can thus move along the linear slide rail 26.
[0042] Specifically, refer to Figure 3 As shown, the upper part of the ejection member 32 is detachably fixed to the push rod slide shaft 31 through the second fixing member 321, and the lower part of the ejection member 32 includes an integrally formed inclined arm 322 and a first pushing member 323; the inclined arm 322 is connected to the middle part of the first pushing member 323; the first pushing member 323 is rectangular, and the long side is perpendicular to the pushing direction of the cigarette box 0.
[0043] It should be noted that if Figure 1 and Figure 4 As shown, the pushing member 33 and the ejecting member 32 can push or eject the cigarette box 0, and can be reset by the reciprocating linear motion of the push rod slide shaft 31, wherein the front end of the pushing member 33, i.e. Figure 1 There is a cigarette box 0 to be transported by the conveyor belt on the left side of the figure. It needs to pass above the cigarette box 0 to be transported and reset before pushing the cigarette box 0 again. Therefore, the pushing member 33 is set as a component with an increased bottom height, so that the pushing member 32 can be vertically raised during the reset movement, thereby avoiding scratching the cigarette box 0 to be pushed in. Since the pushing member 32 has already pushed out the cigarette box 0 on the left side, the reset movement will not be blocked by the cigarette box 0, and therefore it does not need to be vertically raised.
[0044] Specifically, in order to reduce the damage to the cigarette box 0, refer to Figure 4As shown, the pushing member 33 includes a third fixing member 331, a second pushing member 332, and a one-way limiting member 333; the upper part of the third fixing member 331 is detachably fixed to the push rod sliding shaft 31; the two second pushing members 332 are arranged in parallel and are respectively axially connected to the two sides of the third fixing member 331, and can be vertically rotated around the third fixing member 331, and can then be lifted upward; the one-way limiting member 333 is used to press against one side of the second pushing member 332, thereby limiting the rotation of the second pushing member 332 in the pushing direction of the cigarette box 0; it should be noted that the one-way limiting member 333 is understood to limit the rotation of the second pushing member 332 in the pushing direction of the cigarette box 0, but does not limit the rotation of the second pushing member 332 in the reverse direction, such as Figure 4 As shown, the lower limit member is a stop shaft arranged at the upper end of the second pushing member 332; the left side of the stop shaft can be pressed against the second pushing member 332, and since the second pushing member 332 on the right side of the stop shaft is grooved, it will not be pressed, so that the second pushing member 332 can rotate vertically counterclockwise.
[0045] More specifically, the second pushing member 332 includes two pushing pieces disposed on both sides of the third fixing member 331 . The two pushing pieces are connected via a fixed shaft and are thereby lifted synchronously.
[0046] In this embodiment, in order to facilitate the reset of the pusher 33 and further reduce the scratch damage to the cigarette box 0, refer to Figure 4 As shown, the second pushing member 332 is provided with a guide rib 334 inclined in the pushing direction of the cigarette box 0 on the side facing away from the cigarette box 0, so as to lift the second pushing member 332 along the guide rib 334 during the resetting process of the pushing member 33, further reduce friction and lower the scratch rate.

[0051] Specifically, it also includes a control system; the control system is used to control the first servo motor 1 and the second servo motor 6 to cooperate with each other; it should be noted that the control system is a commonly used automation control system such as a single-chip microcomputer, and the first servo motor 1 and the second servo motor 6 can be controlled by connecting the electrical signals of the first servo motor 1 and the second servo motor 6 to the control system.
