Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a loading device for packaging quasi-conical products. Background Art

[0002] The loading device is a commonly used mechanism on the packaging assembly line. For some conventionally shaped products, there are suitable loading mechanisms to choose from. However, for some special-shaped products, such as conical products, due to their irregular structure, conventional loading devices cannot be used directly when loading. For example, conical cigarettes are currently usually packaged manually, which is costly and inefficient. The loading device of existing automatic packaging equipment usually uses a vibrating plate to shake the material apart, and then transfers the material to the subsequent packaging device through a lifting device or a conveyor belt for grabbing and packaging. However, the material of conical cigarettes is relatively soft and has a cone-like shape as a whole. The vibrating plate cannot effectively disperse the accumulated conical cigarettes, resulting in stacking during lifting and transportation. Since the posture of the conical products transported from the lifting mechanism to the assembly line is random, it brings great difficulties to the subsequent grabbing and boxing. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a loading device for packaging cone-like products, including a fixing frame, a material box for containing cone-like products, a lifting mechanism for lifting the cone-like products in the material box upward and conveying them to the assembly line, and also includes a guiding mechanism arranged between the lifting mechanism and the assembly line for guiding the cone-like products and conveying the cone-like products to the assembly line in the same posture.

[0004] On the basis of the above scheme, the conical products are conveyed to the assembly line in the same posture in such a way that all the conical products are fed into the assembly line with their large ends facing forward.

[0005] Based on the above scheme, the guide mechanism includes a rolling plate for receiving the conical products transported on the lifting mechanism and allowing the conical products to roll to the side away from the lifting mechanism by their own gravity; and a guide plate for receiving the conical products sliding down from the rolling plate and allowing the conical products to continue sliding down to the assembly line with the big head facing forward.

[0006] Based on the above solution, the rolling plate and the guide plate both form an angle of 20-26° with the horizontal plane.

[0007] Based on the above solution, a guide groove is provided on the guide plate.

[0008] Based on the above solution, the length of the rolling plate for the quasi-conical product to roll down is 1.5-2.0 times the length of the quasi-conical product; the length of the guide groove for the quasi-conical product to slide down is 1.1-1.6 times the length of the quasi-conical product.

[0009] Based on the above scheme, the lifting mechanism includes a belt driven by a motor, and the belt is provided with a number of raised horizontal grids perpendicular to the conveying direction; a horizontal groove is formed between two adjacent horizontal grids for driving the conical products to move together when the belt moves; the angle α between the belt and the horizontal plane is 50-55°; the angle between the bottom wall of the material box and the belt is 90°.

[0010] Based on the above solution, the maximum spacing of the transverse grooves is greater than 1.5 times the maximum diameter of the large end of the conical product and less than 2 times the maximum diameter of the large end of the conical product.

[0011] Based on the above solution, the cross section of the horizontal grid is trapezoidal, and the side away from the belt is smaller.

[0012] The present invention's loading device for packaging quasi-conical products utilizes a guide mechanism, allowing the quasi-conical products to be adjusted to a uniform posture on the guide mechanism by their own gravity before entering the assembly line. This effectively reduces the operational difficulty of the robot used in the subsequent packaging process, reduces the robot's failure rate, and significantly improves packaging efficiency. The lifting mechanism used in the device is designed with the trapezoidal structure of the horizontal grid, the angle of the belt, the spacing of the horizontal grooves, and the angle between the bottom surface of the material box and the belt, so that the lifting mechanism as a whole achieves a dispersed loading effect. During loading, the quasi-conical products do not accumulate or overlap. This is particularly suitable for loading soft quasi-conical cigarettes, completely replacing the vibrating plate used in existing lifting mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a loading device for packaging conical products, including a fixing frame 1, a material box 2 for containing the conical products, a lifting mechanism 3 for lifting the conical products in the material box 2 upward and conveying them to the assembly line, and also includes a guiding mechanism 4 arranged between the lifting mechanism 3 and the assembly line for guiding the conical products and conveying the conical products to the assembly line in the same posture.

[0026] like Figure 2 As shown, the quasi-conical product described in this application refers to a product whose overall shape is similar to a cone. The quasi-conical product has one large end (diameter A) and one small end (diameter a), and A>a.

[0027] As a product with specific application, the cone-shaped product is a cone-shaped cigarette, which is made of soft material, with paper or tobacco leaves on the outside and tobacco shreds on the inside.

[0028] When packing cone-shaped products, if a gripper-type robot is used, the cone-shaped products will be scratched due to the material problem of the cone-shaped products. Therefore, a suction cup-type robot is selected. Figure 3 As shown, when the traditional feeding mechanism is loading, the quasi-conical products will be directly transported from the lifting mechanism 3 to the assembly line. At this time, the quasi-conical products cannot maintain a certain posture, that is, it is impossible to make the large ends or small ends of the quasi-conical products entering the assembly line face in the same direction. This brings a big problem to the robot arm when packaging on the assembly line, because when the quasi-conical products are loaded into the packaging box or packaging bottle in the same direction, when the large ends or small ends of the two quasi-conical products in front and behind are facing each other, in order to ensure the same direction, the suction cup robot arm needs to rotate 180° after grabbing the first one before grabbing the second one. However, due to the weight and rotation speed of the suction cup robot arm, a large inertia will be formed, which often causes the suction cup robot arm to malfunction. In order to solve this technical problem, it is best to make the quasi-conical products entering the assembly line maintain the same posture, so that the suction cup robot arm does not need to rotate when grabbing.

[0029] The way that the conical products are conveyed to the assembly line in the same posture can be that the large ends of all the conical products enter the assembly line first, or the small ends of all the conical products enter the assembly line first; or all the conical products enter in other directions but all the conical products maintain the same posture.

[0030] like Figure 6 As shown, the present application provides a specific structure of a guide mechanism 4 that allows the large ends of all conical products to enter the production line first.

[0031] The guide mechanism 4 includes a rolling plate 4-1 for receiving the conical products conveyed by the lifting mechanism 3 and allowing the conical products to roll to a side away from the lifting mechanism 3 by their own gravity;

[0032] and

[0033] It is used to receive the conical products sliding down from the rolling plate 4-1 and allow the conical products to continue sliding down to the guide plate 4-2 of the assembly line with the big end facing forward.

[0034] like Figure 4 and Figure 5As shown, after the quasi-conical product falls onto the rolling plate 4-1, it will roll downward under the action of its own gravity (the arc with an arrow is the direction in which the quasi-conical product rolls, and the straight line with an arrow is the direction in which the quasi-conical product moves as a whole). Since the quasi-conical product is a special-shaped structure with one end larger than the other, the larger end is positioned lower. Afterwards, the quasi-conical product will fall onto the guide plate 4-2 and continue to slide down to the assembly line. When the quasi-conical product falls onto the guide plate 4-2, the larger end will first contact the guide plate 4-2.

[0035] In order to make the cone-shaped products fall onto the rolling plate 4-1 and roll down by their own gravity, the angle between the guide mechanism 4 and the horizontal plane is 24°; that is, the rolling plate 4-1 and the guide plate 4-2 both form an angle of 24° with the horizontal plane.

[0036] Specifically, the rolling plate 4-1 is a smooth flat plate, and the guide plate 4-2 is provided with a guide groove 4-3. In order to better adjust the posture of the quasi-conical product, the guide groove 4-3 is a V-shaped groove. If the length of the rolling plate 4-1 for the quasi-conical product to roll down is too short, the posture of the quasi-conical product has not yet been adjusted. At this time, the posture of the quasi-conical product falling into the V-shaped guide groove 4-3 of the guide plate 4-2 is relatively messy, and subsequent posture consistency adjustment cannot be completed; if it is too long, the posture of the quasi-conical product is excessively adjusted due to inertia, which also causes the posture of the quasi-conical product falling into the V-shaped guide groove 4-3 of the guide plate 4-2 to be relatively messy; therefore, the length of the rolling plate 4-1 for the quasi-conical product to roll down is 1.5-2.0 times the length of the quasi-conical product; this length can meet the requirement that the quasi-conical product entering the rolling plate 4-1 laterally is rotated by its own gravity so that its thick end faces forward. Similarly, the length of the guide groove 4-3 for the quasi-conical product to slide down should not be too long or too short. If it is too long, the quasi-conical product will be affected by friction and eventually stay in the V-shaped guide groove of the guide plate 4-2, unable to enter the assembly line. If it is too short, the quasi-conical product will directly enter the assembly line from the rolling plate 4-1 before its posture is completely stabilized. Therefore, the length of the guide groove 4-3 for the quasi-conical product to slide down is 1.1-1.6 times the length of the quasi-conical product.

[0037] Fixing portions 4 - 4 for connecting with the lifting mechanism 3 are provided on both sides of the guide mechanism 4 .

[0038] After using the above-mentioned guide mechanism 4, the conical products entering the production line from the feeding device will maintain the same posture with the big end facing forward, thereby providing a good foundation for the next step of packaging.

[0039] Conventional lifting mechanisms for cylindrical products have no requirements for the arrangement of the products, so the width of the transverse grooves of the lifting mechanisms used is relatively wide, and the cylindrical products have neat and regular shapes and can be stacked and arranged in the wider transverse grooves; when the material is a conical product of the patent (such as conical cigarettes), there are requirements for the arrangement of the material on the assembly line. The width of the transverse grooves of the lifting mechanisms used for conventional cylindrical products is too wide, which will cause the material to stack or get stuck during the lifting process, making it impossible to achieve uniform transportation of the material, affecting the subsequent packaging.

[0040] In order to meet the needs of lifting and loading conical products, this application provides a specific implementation case of a lifting mechanism 3, such as Figure 8 and 9 As shown, the lifting mechanism 3 includes a belt 3-1 driven by a motor, and the belt 3-1 is provided with a plurality of raised horizontal grids (3-2) perpendicular to the conveying direction; a horizontal groove 3-3 is formed between two adjacent horizontal grids 3-2 for driving the conical products to move together when the belt 3-1 moves.

[0041] The maximum spacing of the transverse grooves 3-3 is greater than 1.5 times the maximum diameter of the large end of the conical product and less than 2 times the maximum diameter of the large end of the conical product. This arrangement can prevent the conical products from being overlapped after entering the transverse grooves 3-3.

[0042] The cross section of the horizontal grid 3-2 is trapezoidal, with the side away from the belt 3-1 being smaller. This arrangement can make it easier for the conical products in the material box 2 to enter the horizontal groove.

[0043] The angle α between the belt 3-1 and the horizontal plane is 50-55°, preferably 53°. The angle design between the belt 3-1 and the horizontal plane is directly related to the amount of material loaded. If the angle is too large, the materials will be stacked in the transverse grooves 3-33-3, and finally each transverse groove 3-3 will not have only one layer of material.

[0044] In the prior art, the material box 2 typically uses a vibrating plate to disperse the material through vibration, and then uses a lifting mechanism to lift the dispersed material and transfer it to the subsequent conveyor belt for packaging. When using a vibrating plate for vibration dispersion, due to the soft material and irregular shape of the cone-shaped products, the vibrating plate cannot disperse the material, resulting in subsequent material accumulation. The horizontal grids 3-2 and horizontal grooves 3-3 provided on the belt cannot separate the cone-shaped products, resulting in material loading failure.

[0045] like Figure 8 As shown, the angle between the bottom wall 2-1 of the magazine 2 and the belt 3-1 is 90 degrees. This setting allows the conical products to enter the transverse groove 3-3 in an orderly manner and effectively avoids the problem of multiple products stacking in the same transverse groove 3-3 due to excessive angle.

[0046] When using the device of the utility model to load materials, the following steps are included:

[0047] (1) Place the cone-shaped product into the material box 2;

[0048] (2) Driven by the belt 3-1, the horizontal grid 3-2 continuously brings the conical products in the material box 2 into the horizontal groove 3-3 and continues to lift them upward;

[0049] (3) When lifted to the top, the conical products in the horizontal grid 3-2 roll down from the horizontal grid 3-2 onto the rolling plate 4-1 of the guide mechanism 4;

[0050] (4) The quasi-conical product rolls down along the rolling plate 4-1 under the action of its own gravity. During the rolling process, the quasi-conical product continuously adjusts its posture with the big end facing downward;

[0051] (5) When the quasi-conical product leaves the rolling plate 4-1, the thick end of the quasi-conical product enters the guide groove 4-3 forward and the guide groove 4-3 further adjusts the posture of the quasi-conical product. Then, the quasi-conical product continues to slide along the guide groove 4-3 and finally enters the assembly line.

[0052] When the quasi-conical product leaves the rolling plate 4-1 and enters the guide groove 4-3, the thick end of the quasi-conical product is forward, but at this time, the quasi-conical product is not completely along the direction of the guide groove 4-3. However, due to the effect of the V-shaped guide groove 4-3, the thick posture of the quasi-conical product completes the final adjustment, and the big end moves forward and continues to slide forward along the guide groove 4-3.

[0053] Each embodiment in this specification is described in a related manner. Similar parts between the embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences from other embodiments. The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
