Description

Technical Field

[0001] The present invention relates to an improved invention of a paper towel packaging device, in particular to a cylindrical paper towel packaging device. Background Art

[0002] Tissue paper comes in film packaging, square paper box packaging, and cylinder packaging. Film packaging and square paper box packaging are similar to the square shape of tissue paper and are relatively traditional packaging methods. However, due to the large area they occupy, they are not suitable for use in vehicles. Tissue paper in cylinder packaging can be placed upright, taking up a small area, and is particularly suitable for in-vehicle use. Cylinder packaging is more difficult to produce than film packaging and square paper box packaging. The cylindrical box body is less stable and more difficult to transport and position than the square box body. Moreover, during packaging, the tissue paper, which has been overlapped to a certain thickness, must be rolled into a cylinder before it can be loaded into the cylinder. Due to the difficulty of loading tissue paper into the cylinder, cylinder packaging is currently still done manually, with manual operations from packing the tissue paper into the box to adding the bottom cover. This not only results in low efficiency and high cost, but also poses a health hazard. Summary of the Invention

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a cylindrical tissue packaging device to realize the automated production of cylindrical tissue packaging.

[0005] The cylindrical box body enters the material cavity of the turntable at the loading station and is locked in the material cavity. The turntable sends the cylindrical box body to the feeding station and the capping station in sequence for feeding and capping respectively. After packaging is completed, the cylindrical box body leaves the material cavity and is discharged at the discharging station, realizing automatic transportation of the box body and solving a major problem of box body transportation in cylindrical tissue packaging.

[0006] As an advantage, the loading station is provided with a box loading mechanism, which includes

[0007] The loading bin includes a mounting plate, side baffles and a material stopper. The mounting plate is provided with a box body outlet, the box body outlet is directly opposite to the opening of the material chamber, the side baffles are arranged at both ends of the box body outlet, the spacing between the two side baffles matches the length of the box body, and the material stopper is arranged on one side of the box body outlet;

[0008] A pressing plate that moves back and forth relative to the box outlet;

[0009] And a material guiding component, which is provided with a material guiding channel, and the material guiding channel is connected with the cavity of the upper material bin.

[0010] The box body is in a horizontal state and enters the cavity of the loading bin through the material guide channel. The side baffles prevent the box body from rotating in the cavity, but maintain a horizontal longitudinal state in the cavity, that is, the loading state. Then, the pressing plate pushes the box body to pass through the box body outlet and press the box body into the material cavity. Finally, the box body is locked in the material cavity to realize automatic loading of the box body.

[0011] Preferably, a loading pusher is provided on the other side of the box body outlet, and the loading pusher moves back and forth relative to the blocking member; the material guiding component includes a first guide plate, a second guide plate and a third guide plate, the first guide plate includes a first section inclined downward and a second section arranged vertically, the second guide plate is arranged parallel to the first section of the first guide plate, and the third guide plate is arranged vertically above the box body entrance, and the first guide plate, the second guide plate and the third guide plate form a material guiding channel. After the box body enters the loading bin, the loading pusher pushes the box body to move to the box body outlet, ensuring that the box body reaches the loading position, so that the pressing plate can smoothly press the box body into the material cavity; the inclined first section of the material guiding channel can better connect with the conveying part of the box body, and the vertically arranged second section enables the boxes to be stably stacked and the boxes to enter the loading bin one by one.

[0012] As an option, the feeding station is provided with a feeding mechanism, which includes

[0013] Tubing parts, including

[0014] Support parts,

[0015] The limiting member is arranged above the supporting member.

[0016] and a cylinder-forming member that rises and falls, which has a cylinder-forming cavity, the cross section of which is arc-shaped, the opening of which faces the upper limit member, and the cylinder-forming member is provided with a notch for the support member to pass through;

[0017] and a pushing component, which includes a longitudinally movable feed pushing component, the feed pushing component facing the feed end of the material cavity of the feed station, the feed pushing component being arranged above the supporting component, and the feed pushing component being provided with a first notch for the limiting component to pass through.

[0018] Before the paper towels are fed into the container, the roll-forming member moves upward, pushing the paper towels on the supporting member upward. When the middle position of the paper towels is blocked by the limit member, the roll-forming member continues to move upward, and the paper towels are pressed into the roll-forming cavity. The two sides of the paper towels move toward each other and are roughly in the shape of a cylinder. Then, the feeding pushing member moves toward the feeding station, pushing the rolled paper towels into the cylindrical box body of the feeding station, thereby realizing automatic feeding of cylindrical packaging.

[0019] Preferably, the end of the stopper near the turntable is provided with an introduction sleeve, the introduction sleeve having an introduction channel, which is connected to the feeding end of the material chamber of the feeding station; the stopper is a thin, vertically arranged limiting plate, the bottom surface of which is a circular arc surface. The introduction sleeve serves to assist in feeding, allowing the rolled paper towels to smoothly enter the cylindrical box along the introduction channel; the thin thickness of the limiting plate occupies little space, thereby not occupying the position where the paper towels are rolled. At the same time, the stress between the circular arc bottom surface and the paper towels is reduced, which can prevent the paper towels from being damaged during rolling and feeding.

[0020] Preferably, the feeding end of the material supporting member is connected to the discharging end of the conveying member, and the conveying member includes a conveying platform for longitudinal conveying, and a material extraction member that rises and falls is provided above the conveying platform. During the extraction operation, the material extraction member moves downward to obtain the first tissue on the conveying platform, and the material extraction member moves longitudinally relative to the conveying platform. The tissues to be packaged are placed on the conveying platform, and the material extraction member moves downward to absorb or clamp the first tissue. The material extraction member moves longitudinally relative to the conveying platform, causing the absorbed or clamped first tissue to be displaced, that is, the first tissue partially leaves the stacking area to form an exposed portion. After boxing, this exposed portion of the first tissue is used for extraction. After the tissues are extracted, the material extraction member releases the tissue and moves upward to reset.

[0021] As an advantage, the capping station is provided with a box body capping mechanism, and the box body capping mechanism includes

[0022] The cover supporting plate is provided with an in-place station, the turntable is in front of the in-place station, the in-place station is provided with a side stopper, and the in-place station is communicated with the box cover channel;

[0027] The lids in the lid channel enter the transition station and then the in-place station, where they are fed in sections one by one, improving feeding stability. After the lids are pushed to the in-place station, the rear cover stopper blocks them to prevent them from tipping over. The notch on the first cover pusher prevents them from colliding with the rear cover stopper.

[0028] Preferably, the discharging station is provided with a discharging mechanism, which includes a discharging pusher and a driving assembly for driving the discharging pusher to move relative to the opening of the material cavity of the discharging station;

[0029] Before the material cavity is in place, the material discharging and pushing member moves toward the center of the turntable and moves to between the material cavity and the center of the turntable;

[0030] When the material cavity rotates to the discharging station, the discharging pushing piece moves toward the opening direction and pushes the box body to separate from the material cavity.

[0031] Preferably, the material chamber is equipped with a stopper protrusion connected to a spring that pushes the stopper protrusion into the material chamber. The material chamber is disposed on a mounting base, which is mounted on a turntable. The turntable is provided with a feed notch corresponding to the material chamber. When the box body enters the material chamber, the spring force causes the stopper protrusion to press against the box body, locking it within the material chamber. During discharge, the box body is pushed away from the stopper protrusion and discharged from the material chamber. By increasing the thickness of the mounting base and the width of the material chamber, the box body is more stable within the material chamber, while the turntable can maintain an appropriate thickness. Moreover, the mounting base can be replaced with a desired thickness according to the length of the box body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. In the drawings, the X axis is the horizontal direction, also the left-right direction, the Y axis is the longitudinal direction, also the front-back direction, and the Z axis is the vertical direction, also the up-down direction.

[0034] This type of cylindrical tissue packaging equipment includes a transmission component, which includes a turntable 11. The turntable is provided with a loading station 6, a feeding station 7, a capping station 8 and a discharging station 9 in sequence in the circumferential direction of the turntable. A plurality of material cavities 12 are provided on the turntable, and the material cavities are evenly distributed along the circumferential direction of the turntable. The opening of the material cavity 12 faces the outer circumference of the turntable, and one end of the material cavity is the feeding end. The depth of the material cavity 12 is not less than the radius of the box body. The depth here refers to the radial direction, not the length direction. The material cavity is locked with the box body 10, that is, the box body enters the material cavity. In the absence of external force, the box body will not leave the material cavity. Because the box body is cylindrical, if the depth of the material cavity is less than the radius of the box body, the box body can easily detach from the material cavity. The cylindrical box body enters the material cavity of the turntable at the loading station 6 and is locked in the material cavity. The turntable sends the cylindrical box body 10 to the feeding station 7 and the capping station 8 in sequence for feeding and capping respectively. After the packaging is completed, the turntable 11 sends the cylindrical box body to the discharging station 9, and the cylindrical box body is separated from the material cavity and discharged, realizing the automatic transportation of the box body and solving a major problem of box body transportation in cylindrical tissue packaging.

[0035] The wider the width of the material cavity 12, the more stable the box body 10 in the material cavity. The material cavity can be directly set on the turntable 11. However, increasing the thickness of the turntable will increase the weight of the turntable and the processing cost. In this embodiment, the material cavity is set on the mounting seat 16, and the mounting seat is installed on the turntable 11. The turntable is provided with a feeding notch 17 corresponding to the material cavity. The material enters the box body through the feeding notch. By increasing the thickness of the mounting seat 16 and increasing the width of the material cavity, the box body is more stable in the material cavity, and the turntable 11 only needs to maintain an appropriate thickness. This greatly reduces the equipment cost and the power required for the turntable. In addition, the mounting seat of the required thickness can be replaced according to the length of the box body. The locking cooperation between the material cavity and the box body can be carried out in different ways. For example, the material cavity and the box body are tightly matched, and the box body is locked in the material cavity by the friction between the material cavity and the box body, but this method can easily cause damage to the surface of the box body; see the attached figure, the material cavity is equipped with a limiting protrusion 15, and the limiting protrusion is connected to a spring. The spring is not drawn in the figure, and the spring pushes the limiting protrusion into the material cavity, that is, the mounting seat is provided with a mounting groove, and one end of the spring and the limiting protrusion is placed in the mounting groove. In the absence of external force, the elastic force of the spring pushes the other end of the limiting protrusion into the material cavity 12. When the box body 10 enters the material cavity, the limiting protrusion 15 is squeezed and the limiting protrusion is pressed into the mounting groove. At the same time, the elastic force of the spring causes the limiting protrusion to support the box body 10 and lock the box body in the material cavity 12. When discharging, the box body is pushed to leave the limiting protrusion 15, and the box body is discharged from the material cavity. The surface of the limiting protrusion is arc-shaped, which avoids damaging the surface of the box body when it contacts the box body; the limiting protrusion is provided in two groups and is symmetrically arranged with respect to the center line of the material cavity, so that the locking effect is better. In order to further enhance the locking effect, each group can be provided with two horizontally arranged limiting protrusions, that is, two limiting protrusions are provided on one mounting seat; in the figure, one group has only one limiting protrusion. The turntable 11 is provided with two disk surfaces, namely a first disk surface 13 and a second disk surface 14, which are coaxially arranged. The first disk surface is the feeding end surface, and the feeding notch 17 is provided on the first disk surface 13, while the second disk surface may not be provided with a notch; the mounting seat 16 is provided in two groups, which are respectively installed on the first disk surface and the second disk surface, and the two mounting seats are arranged facing each other with a certain distance 18 between the two mounting seats. In this way, both ends of the box body are locked in the material cavity, which improves stability and is particularly suitable for boxes with longer lengths. The material cavity 12 includes an interior 19 and an opening 20, wherein the interior is semicircular and matches the box body, and the opening is a portion of the semicircular interior that extends horizontally outward with a maximum diameter, and the limiting protrusion 15 is arranged at the critical point between the opening and the interior; when the box body 10 enters the material cavity 12, half of the box body is in the interior 19 of the material cavity, and the limiting protrusion 15 just presses against the maximum diameter of the box body, ensuring that the limiting protrusion locks the box body.

[0036] The loading station 6 is provided with a box loading mechanism 1, which includes a loading bin 103, a pressure plate 117 and a material guide component 113. The loading bin includes a mounting plate 114, a side baffle 115, a baffle 116 and a loading pusher 119, which form the loading bin 103. A box outlet 120 is provided on the mounting plate, and the box outlet is facing the opening of the material cavity 12. The side baffles 115 are provided at both ends of the box outlet, and the spacing between the baffles on both sides is the same as that of the box. That is to say, the length of the cavity of the loading bin matches the length of the box body. After the box body 10 enters the cavity of the loading bin in a longitudinal horizontal state, it will not rotate in the cavity. The blocking member 116 is arranged on one side of the box body outlet, and the loading pushing member is arranged on the other side of the box body outlet, and the loading pushing member moves back and forth relative to the blocking member; the pressing plate 117 moves back and forth relative to the box body outlet; the material guiding component 113 is provided with a material guiding channel, and the material guiding channel is connected to the cavity of the loading bin. In the figure, the loading bin 103 is above the material cavity 12, and the pressing plate 117 rises and falls relative to the box body outlet 120. The material blocking member 116 is on the left side of the box body outlet. The material blocking member can be a material blocking block or a material blocking plate. The loading pushing member is arranged on the right side of the box body outlet. The box body 10 is in a longitudinal horizontal state and enters the cavity of the loading bin 103 through the material guide channel. The box body is in a longitudinal horizontal state, that is, the loading state. The loading pushing member 119 moves toward the material blocking member 116, pushing the box body to move it to the box body outlet 120, ensuring that the box body reaches the loading position, and then, the pressing plate 117 moves downward to push the box body to pass through the box body outlet 120, and press the box body into the material cavity 12. Finally, the box body is locked in the material cavity, thus realizing automatic loading of the box body. The material guide component includes a first guide plate 121, a second guide plate 122 and a third guide plate 123. The first guide plate includes a first section inclined downward and a second section arranged vertically. The second guide plate 122 is arranged parallel to the first section of the first guide plate. The third guide plate 123 is arranged vertically, and there is a material passing distance between the third guide plate and the mounting plate 114. That is, the box body enters the cavity and can pass through the material passing distance to enter the loading position. The first guide plate 121, the second guide plate 122 and the third guide plate 123 form a material guide channel, that is, the material guide channel The conveyor belt has an inclined first section and a vertically arranged second section. The inclined first section can better connect with the conveying part of the box body. The conveying part of the box body can adopt a conveyor belt, and the box body can slide smoothly to the second section due to gravity. The vertically arranged second section enables the box bodies to be stacked stably and the box bodies enter the loading bin one by one, and the loading push plate 119 will push the box body material that enters the loading bin and is ranked first to the loading position. Only the box body ranked first can pass through the material gap and enter the loading position. After the box body is sent out and the loading push piece is reset, the box body automatically moves down due to gravity.The second section of the first guide plate 121 extends onto the mounting plate 114, completely guiding the box body onto the mounting plate to improve the stability of material feeding. The first guide plate is provided with a push port 127 for the material loading and pushing member to pass through, so as not to affect the movement of the material loading and pushing member. The first guide plate includes a support plate 125, a first side plate 124, and a second side plate 126. The first and second side plates are mounted on the support plate 125, and the spacing between the first and second side plates matches the length of the box body, so that the box body moves in a longitudinal horizontal state within the material guide channel. In the figure, the support plate is not complete, but is divided into two pieces with a gap between the two pieces. This gap can serve as a push port 127 for the material loading and pushing member 119 to pass through. The end of the pressing plate close to the loading and pushing piece is upwardly extended with a baffle plate 118. When the pressing plate 117 moves toward the box body outlet, the baffle plate blocks the next box body, so that the box body stays between the baffle plate 118 and the support plate 125. This not only enables the subsequent box bodies to be stacked neatly, but also when the pressing plate 117 is reset, the next box body will not affect the reset of the pressing plate; the lateral position of the baffle plate is close to that of the third guide plate, and the distance between the two and the support plate is preferably matched with the outer diameter of the box body. Such a distance can only accommodate one box body, and will not cause blockage of the box body.

[0037] The feeding station 7 is provided with a feeding mechanism 2, and the feeding mechanism 2 includes a barrel-forming component and a pushing component. The barrel-forming component includes a supporting component 205, a limiting component 203 and a barrel-forming component 204 that rises and falls. The limiting component is arranged above the supporting component, and side baffles 217 are arranged on both sides of the supporting component. The spacing between the baffles on both sides matches the material, and the baffles on both sides and the supporting component form a material cavity, which can accurately position the paper towel and improve the quality of barreling; the barrel-forming component 204 has a barrel-forming cavity 208, and the cross-section of the barrel-forming cavity is arc-shaped. The opening of the barrel-forming cavity faces the upper limiting component 203, and the barrel-forming component is provided with a notch 209 for the supporting component to pass through. When the barrel-forming component moves up, the supporting component 205 passes through the notch, which will not affect the lifting of the barrel-forming component 204. The barrel-forming cavity in the figure is roughly semi-cylindrical, that is, the cross-section is semi-circular, so the opening is large, which is conducive to the paper towel 207 entering the barrel-forming cavity 208, and at the same time can make the paper towel into a barrel. The pushing component includes a longitudinally movable feed pushing piece 202, which is arranged above the supporting piece, and a first notch 221 for the limiting piece to pass through is provided on the feed pushing piece. When the feed pushing piece moves forward, the limiting piece 203 enters the first notch 221, which will not affect the movement of the feed pushing piece 202. When the paper towel 207 enters the material cavity, the drum-forming member 204 moves upward, pushing the paper towel on the material support member upward. The stopper is preferably set in the middle position of the drum-forming member, so that the middle position of the paper towel is blocked by the stopper 203. As the drum-forming member moves upward, the two sides of the paper towel are forced to move toward each other, and the paper towel is formed into a cylinder with the stopper as the center and pressed into the drum cavity 208. Then, the feeding pusher 202 moves toward the feeding station 7, pushing the rolled paper towel into the cylindrical box body of the feeding station, realizing automatic feeding of the cylindrical packaging; after the feeding is completed, the drum-forming member 204 moves downward and resets, and the feeding pusher 202 retreats and resets until the next material enters the material cavity. The stopper 203 is provided with an introduction sleeve 206, which is set in the feeding station 7, close to the cylindrical box body, and has an introduction channel. After being rolled, the paper towels first pass through the introduction sleeve before entering the cylindrical box. The introduction sleeve serves to assist in the introduction process, allowing the rolled paper towels to smoothly enter the cylindrical box along the introduction channel, making feeding more stable. The inner diameter of the inlet 219 of the introduction channel is larger than the inner diameter of the outlet 220 of the introduction channel. The inner diameter of the outlet of the introduction channel is no larger than the inner diameter of the packaging tube, and preferably the inner diameter of the outlet of the introduction channel is slightly smaller than the inner diameter of the packaging tube, which is more conducive to the feeding of paper towels. The inner diameter of the inlet of the introduction channel is larger than the inner diameter of the outlet of the introduction channel, which facilitates the entry of the rolled paper towels into the introduction channel. Through the squeezing of the introduction channel, the outer diameter of the rolled paper towels meets the feeding requirements.As shown in the attached drawings, the limiting member 203 is a thin sheet-shaped limiting plate arranged vertically. The bottom surface of the limiting plate is a circular arc surface 218. The outer diameter of the circular arc surface can be slightly larger than the thickness of the limiting member. The thin thickness of the limiting plate occupies little space, so it will not occupy the position of the paper towel roll. In this way, the two ends of the paper towel roll are closer. At the same time, the surface of the circular arc surface is smooth and will not scratch the paper towel. Moreover, when the limiting member is pressed against the paper towel, the stress between the circular arc surface 218 and the paper towel 207 is small, which can avoid damage to the paper towel during roll formation and feeding, thereby ensuring the quality of the paper towel. The supporting member 205 is a narrow strip, and one or two can be provided. The narrow width of the supporting member corresponds to the narrow width of the notch 209, which prevents the paper towel from squeezing into the notch. If the notch is too wide, the paper towel may be squeezed into the notch during roll formation, resulting in feeding failure. The feeding end of the material supporting member is connected with the discharging end of the conveying member 3. The conveying member includes a conveying platform for longitudinal conveying. A material extraction member 308 that can be lifted up and down is provided above the conveying platform. The lifting of the material extraction member can be performed by a cylinder 316. During the extraction operation, the material extraction member moves down to obtain the first paper towel on the conveying platform, and the material extraction member and the conveying platform move longitudinally relative to each other, so that the first fixed paper towel is displaced relative to the paper towels stacked below it. The material extraction member can be a suction member or a clamping member, that is, the material extraction member can move down to obtain the material by adsorbing the paper or clamping the paper towel. Both methods can fix and obtain the paper towel. The material extraction member includes a suction nozzle, which is connected to the air source. When taking the material, the suction nozzle absorbs the paper towel. The clamping member includes a first clamping plate and a second clamping plate that can be opened and closed. When taking the material, the first clamping plate and the second clamping plate are closed to clamp the paper towel. In the accompanying drawings, a suction element is used, and the following description uses the suction element as the extraction element. In actual application, a clamping element can be used instead of the suction element. The first tissue paper partially leaves the stacking area 317 to form an exposed portion 318. After boxing, this exposed portion of the first tissue paper is used for extraction, which can also be called the extraction portion. After the tissue paper is extracted, the suction element releases the tissue paper and moves upward to reset. The suction member 308 can move longitudinally relative to the conveying platform in several specific situations. For example, the suction member is stationary, and when the conveying platform moves forward, the suction member retreats relative to the conveying platform, so that the first paper towel is pulled out backward; for example, the conveying platform conveys intermittently, and during the pulling-out operation, the conveying platform stops, and the suction member moves longitudinally to pull out the first paper towel; for another example, the conveying platform conveys continuously, and the suction member is connected to a drive assembly 309 that drives it to move between the suction station and the in-place station, and the in-place station is in front of the suction station, and the speed at which the drive assembly drives the suction member 308 from the suction station to the in-place station is faster than the speed at which the conveying platform conveys; during the pulling-out operation, the conveying platform keeps conveying, the suction member moves downward to absorb the first paper towel, and the speed at which the drive assembly drives the suction member to move is faster than the conveying platform, so that the first paper towel moves forward relative to the paper towels stacked on the conveying platform, and the first paper towel partially leaves the stacking area to form an exposed extraction portion; after the pulling-out is completed, the drive assembly drives the suction member back to the suction station.The suction member 308 moves back and forth between the suction station and the in-place station, and can adopt a linear movement method or a swinging method. The suction station can be directly in front of the in-place station or obliquely in front of the in-place station, which can be selected according to needs. In this embodiment, the in-place station is directly in front of the suction station, and the driving component drives the suction member to move back and forth in a straight line. Relatively speaking, the linear movement stroke is short and the speed is faster. The driving component can use a cylinder to directly drive the suction member to move back and forth between the suction station and the in-place station, or other methods can be adopted, see the attached figure, frame A linear guide 314 is provided on it, and the linear guide is arranged longitudinally. The suction piece 308 is slidably arranged on the linear guide, and the movement through the linear guide is more stable. The driving assembly includes a connecting rod 315, a swing arm 313 and a power source for driving the swing arm to swing. The power source can be a motor. The swing arm is hinged to the frame, one end of the connecting rod 315 is hinged to the swing arm, and the other end of the connecting rod is connected to the suction piece 308. The power source drives the swing arm to swing, and the swing arm drives the suction piece to move forward or backward along the linear guide through the connecting rod, thereby realizing back and forth movement between the suction station and the in-place station. The conveyor platform can adopt belt conveying or transmission chain combined with push rod conveying, etc. The present invention combines two types of conveying. The conveyor platform includes a first conveying section 311 and a second conveying section 312. The first conveying section includes a conveyor belt 310, and the conveyor belt conveys longitudinally. The conveyor belt is divided into a first conveyor belt 301 and a second conveyor belt 302; the second conveying section includes a transmission belt, a push rod 303 and a support plate 305. There are several push rods. The push plates 303 are vertically arranged and evenly arranged on the transmission belt. The transmission belt partially overlaps with the conveyor belt 310, that is, the starting end of the second conveying section 312 overlaps with the tail end of the first conveyor belt 311. The push rod is arranged between the first conveyor belt and the second conveyor belt.
