Description

Technical Field

[0001] The invention relates to the technical field of tobacco processing equipment, and in particular to a rod-shaped object positioning and separation device. Background Art

[0002] Cigarettes are a type of tobacco product. The traditional production process of filter cigarettes is to cut a double-length cigarette in half and separate them. Then, a double-length filter is placed between the two cigarettes and the filter and two cigarettes are wrapped with filter tipping paper. Finally, the filter is cut along the center to form two filter cigarettes. The two cigarettes are symmetrically distributed along the filter cutting plane. Before being handed over to the downstream machine, the two filter cigarettes must be rearranged so that their filters are facing the same direction. This process is generally achieved by a three-wheel system containing two conical drum wheels.

[0003] The production process of the new type of cigarette is to cut a double-length cigarette in the middle and separate it, then put in a double-length smoking section, and then cut it twice from the middle of the smoking section. After cutting, the two cigarettes with smoking sections are rotated and turned around, and symmetrically separated for a distance. After putting a double-length filter in the separation point, it is wrapped with filter tipping paper, and cut three times in the middle of the filter, and finally two new filter cigarettes with filters and smoking sections are formed. The process requires that after the smoking section and filter are cut, the cut cigarettes are turned around and separated, and then cut. In order to place other raw materials between the opened smoking sections, the two cut cigarettes must be placed on the same drum and turned so that the smoking sections of the two cigarettes are facing each other, and there is sufficient distance between the two cigarettes to enable timely progress to the next process. Traditional cigarette production equipment turns and sorts the entire row of cigarettes, which cannot be directly applied to the production of new tobacco.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0045] When used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0046] Please participate Figure 1-Figure 3 , a rod-shaped object positioning and separation device, comprising:

[0047] The fixed cylinder is divided into a feeding cylinder, a positioning cylinder and a receiving cylinder, and includes a fixed cylinder 1, a negative pressure cylinder 4, a first sealing ring 7, an inner cylinder 8, a second sealing ring 11 and a connecting cover 12, wherein:

[0048] The negative pressure cylinder 4 includes an air pressure cylinder body 41, a connecting hole 42 and a negative pressure port 43, wherein:

[0049] The air pressure cylinder 41 is provided outside the fixed cylinder 1 . The outer surface of the air pressure cylinder 41 is provided with a communication hole 42 and the negative pressure port 43 . A cavity is formed between the air pressure cylinder 41 and the fixed cylinder 1 .

[0050] An inner cylinder 8, which is arranged outside the air pressure cylinder 41 and is fixed to one end of the connecting cover 12 by screws;

[0051] Based on the above, an inner cavity is formed between the fixed cylinder 1, the negative pressure cylinder 4 and the inner cylinder 8. When negative pressure is introduced into the negative pressure port 43, negative pressure is generated inside the inner cavity. At this time, negative pressure is also generated on the outer surface of the inner cylinder 8, that is, the effect of using negative pressure to adsorb the material can be achieved, and the first sealing ring and the second sealing ring both play a sealing role, ensuring the sealing of the interior of the fixed cylinder.

[0052] like Figures 9-16 As shown, the inner cylinder 8 includes a first adjustment inner cylinder 81, a second adjustment inner cylinder 82, a receiving inner cylinder 83 and a feeding inner cylinder 84, wherein,

[0053] The first position adjustment inner cylinder 81 and the second position adjustment inner cylinder 82 are respectively arranged outside the position adjustment cylinder;

[0054] The receiving inner cylinder 83 and the feeding inner cylinder 84 are respectively arranged outside the receiving cylinder and the feeding cylinder;

[0055] A second sealing ring 11 is provided inside the inner cylinder 8;

[0056] The first adjustment inner cylinder 81 includes a first inner cylinder body 811 , and the upper surface of the first inner cylinder body 811 is provided with first longitudinal adsorption holes 812 and first transverse adsorption holes 813 . The first longitudinal adsorption holes 812 are symmetrically distributed, and the total curvature of the first longitudinal adsorption holes 812 and the curvature of the first transverse adsorption holes 813 on both sides are both between π and 13 / 9π.

[0057] The second adjustment inner cylinder 82 includes a second inner cylinder body 821. The upper surface of the second inner cylinder body 821 is provided with second transverse adsorption holes 823 and second longitudinal adsorption holes 822. The second longitudinal adsorption holes 822 are symmetrically distributed. The total curvature of the second longitudinal adsorption holes 822 on both sides and the curvature of the second transverse adsorption holes 823 are not less than 8 / 9π.

[0058] Based on the above, negative pressure is generated at the first longitudinal adsorption hole 812 and the first transverse adsorption hole 813 on the surface of the first positioning inner cylinder 81. The longitudinal suction force generated at the first longitudinal adsorption hole 812 is the adsorption force toward the center of the fixed cylinder 1, and the first transverse adsorption hole 813 generates a transverse adsorption force. The second transverse adsorption hole 823 has the same function as the first transverse adsorption hole 813, and the second longitudinal adsorption hole 822 has the same function as the first longitudinal adsorption hole 812. Since the second longitudinal adsorption hole 822 and the first longitudinal adsorption hole 812 are symmetrically distributed on the left and right, there is a weakest point of adsorption force, that is, the position of the highest point of the two positioning inner cylinders where the longitudinal adsorption holes on both sides are not connected, and the arc range of the above-mentioned adsorption holes is to ensure that the first positioning cylinder 91 and the second positioning cylinder 92 can cooperate with the receiving outer cylinder 93 and the feeding outer cylinder 94 to ensure that the material will not be separated when it is driven to move;

[0059] The material receiving inner cylinder 83 includes a material receiving inner cylinder body 831, and a material receiving adsorption hole 832 is provided on a side of the material receiving inner cylinder body 831 close to the positioning cylinder. The curvature of the material receiving adsorption hole 832 is not less than π. The material feeding inner cylinder 84 includes a material feeding inner cylinder body 841, and a material feeding adsorption hole 842 is provided on the upper surface of the material feeding inner cylinder body 841. The curvature of the material feeding adsorption hole 842 is not less than 4 / 3π.

[0060] Based on the above, the feeding adsorption hole 842 and the receiving adsorption hole 832 both have the effect of generating longitudinal adsorption force. By limiting the curvature of the above two adsorption holes, the material will not fall off before being fed to the two adjusting cylinders, and when the material moves to the position in contact with the adjusting cylinder, the adsorption force disappears, and the material can be transferred. The effect of the receiving adsorption hole 832 is consistent with that of the feeding adsorption hole 842.

[0061] like Figure 3 As shown, the transmission mechanism includes a transmission shaft 13, a gear 14, a limit cover 15, a connecting ring plate 16 and a sealing block 17, wherein:

[0062] The transmission shaft 13 is arranged inside the fixed cylinder 1 through the rotating sealing ring 10 and the bearing 3;

[0063] Based on the above, the transmission shaft 13 drives the limit cover 15, the connecting ring plate 16 and the sealing block 17 to rotate. During this process, the connecting ring plate 16 and the limit cover 15 drive the outer cylinder 9 to rotate, so as to achieve the effect that the inner cylinder 8 remains stationary while the outer cylinder 9 rotates.

[0064] like Figure 4-Figure 8 As shown, the outer cylinder 9 is arranged outside the inner cylinder 8 and connected to the limiting cover 15, and includes a first positioning cylinder 91, a second positioning cylinder 92, a material receiving outer cylinder 93 and a material feeding outer cylinder 94;

[0065] The first positioning cylinder 91 includes a first positioning cylinder body 911. The outer surface of the first positioning cylinder body 911 is provided with a first sliding groove 912. The inner wall of the first sliding groove 912 is provided with a first adsorption hole 913 and a first positioning hole 914. The first adsorption hole 913 corresponds to the first longitudinal adsorption hole 812, and the first positioning hole 914 corresponds to the first transverse adsorption hole 813.

[0066] The second positioning cylinder 92 includes a second positioning cylinder body 921, the outer surface of the second positioning cylinder body 921 is provided with a second sliding groove 922, the inner wall of the second sliding groove 922 is provided with a second adsorption hole 923 and a second positioning hole 924, the second positioning hole 924 corresponds to the second transverse adsorption hole 823, the second adsorption hole 923 corresponds to the second longitudinal adsorption hole 822, the second sliding groove 922 and the first sliding groove 912 are staggered, and an annular plate 5 is provided on the end of the first positioning cylinder 91 close to the limiting cover 15 and the end of the second positioning cylinder 92 away from the limiting cover 15 respectively.

[0067] Based on the above, the first adjusting cylinder 91 is used in conjunction with the first adjusting inner cylinder 81, that is, suction is generated at the first adsorption hole 913 to absorb the material. When the material follows the first adjusting cylinder 91 to move to the highest point, the suction disappears. At this time, the first transverse adsorption hole 813 still retains the suction. The second adjusting cylinder 92 has the same working principle as the first adjusting cylinder 91. The second adjusting cylinder 92 is used in conjunction with the second adjusting inner cylinder 82. The difference between the first adjusting cylinder 91 and the second adjusting cylinder 92 is only that the duration of their longitudinal adsorption force is different. This is because the positional relationships between the two adjusting cylinders 91 and the receiving outer cylinder 93 and the feeding outer cylinder 94 are different, resulting in different paths for material handling, and therefore different times for adsorbing materials.

[0068] The material receiving outer cylinder 93 includes a material receiving outer cylinder body 931, an outer surface of the material receiving outer cylinder body 931 is provided with an outer ring block 932, an outer surface of the outer ring block 932 is provided with a material receiving groove 933, an inner wall of the material receiving groove 933 is provided with a material receiving hole 934, and the material receiving hole 934 corresponds to the material receiving adsorption hole 832. The material feeding outer cylinder 94 includes a material feeding outer cylinder body 941, an outer surface of the material feeding outer cylinder body 941 is provided with a material feeding groove 942, an inner wall of the material feeding groove 942 is provided with a material feeding hole 943, and the material feeding hole 943 corresponds to the material feeding adsorption hole 842;

[0069] Based on the above, the receiving outer cylinder 93 is used in conjunction with the receiving inner cylinder 83, and the feeding outer cylinder 94 is used in conjunction with the feeding inner cylinder 84, wherein the feeding hole 943 and the feeding adsorption hole 842 only play the role of adsorbing the material, and when the material moves to the position where the two adjustment cylinders contact, the adsorption force disappears, which facilitates the transfer of the material. The receiving hole 934 and the receiving adsorption hole 832 are based on the same principle as the above two holes, but the receiving holes 934 on both sides correspond to the first adjustment cylinder 91 and the second adjustment cylinder 92 respectively;

[0070] The material receiving block 6 can be arranged on the outer surface of the first positioning cylinder 91 and the second positioning cylinder 92. The material receiving block 6 includes a block 61. The block 61 can be arranged inside the first sliding groove 912 and the second sliding groove 922. The block 61 is provided with an air hole 62 and a notch 63 on the side close to the fixed cylinder 1. The air hole 62 is connected to the notch 63. The notch 63 can form an adsorption chamber 18 between the first positioning cylinder 91 and the second positioning cylinder 92.

[0071] The tile plate 2 is respectively arranged above the first positioning cylinder 91 and the second positioning cylinder 92;

[0072] Based on the above, the adsorption chamber 18 is coordinated with the tile plate 2. When the adsorption chamber 18 has not moved to the tile plate 2, since the adsorption chamber 18 is directly in contact with the external space through the air hole 62, the lateral adsorption force of the adsorption chamber 18 is small and the effect of material movement cannot be achieved. When the adsorption chamber 18 moves to the tile plate 2, the air hole 62 is blocked, thereby increasing the lateral adsorption force of the adsorption chamber 18, and the first sliding groove 912 and the second sliding groove 922 are blocked by the tile plate 2, and the lateral adsorption force inside them is greatly increased to achieve the lateral movement of the material to the position of the receiving block 6. In this process, the material moves in opposite directions, that is, the material moves to the farthest ends of the first sliding groove 912 and the second sliding groove 922.

[0073] In actual use, this embodiment is connected to the negative pressure device through the negative pressure port 43, so that the negative pressure is generated inside the negative pressure cylinder 4. At this time, negative pressure is formed in the space between the negative pressure cylinder 4, the inner cylinder 8 and the outer cylinder 9, and the receiving outer cylinder 93 and the feeding outer cylinder 94 are driven by the transmission mechanism to Figure 2 The first adjusting cylinder 91 and the second adjusting cylinder 92 rotate clockwise based on Figure 2 Rotate counterclockwise as the reference;

[0074] During this process, negative pressure is generated at the feeding hole 943, sucking the material into the feeding trough 942. At this time, the material is divided into two circles, the front and rear circles. When the material follows the feeding outer cylinder 94 to the position of contact with the first adjustment cylinder 91, the rear circle of material (i.e., the material on the side away from the sealing block 17) is sucked into the position of the first suction hole 913. When the front circle of material (i.e., the material on the side close to the sealing block 17) moves to the second adjustment cylinder 92, it is sucked into the interior of the second suction hole 923.

[0075] When the material moves to the highest point following the position adjustment cylinder, the tile plate 2 blocks the air hole 62, thereby increasing the adsorption force at the adsorption chamber 18 and weakening the adsorption force at the first adsorption hole 913 and the second adsorption hole 923. At this time, the material moves laterally under the action of the lateral adsorption force, that is, the material in the first sliding groove 912 moves in a direction away from the sealing block 17, while the material in the second sliding groove 922 moves in a direction close to the sealing block 17, thereby achieving the effect of adjusting the position and turning the material.

[0076] At this time, the adjusted and diverted material moves to the receiving barrel and is sucked into the receiving trough 933;

[0077] The device is equipped with two receiving barrels, and the two adjacent materials move crosswise, such as Figure 19 As shown, when the uppermost material A and the material B are placed side by side, they are in the inner portion of the feeding outer cylinder 94. The material A and the material B are respectively transferred to the inner portions of the first adjustment cylinder 91 and the second adjustment cylinder 92. Figure 19 In the second step, the two materials are adjusted and the horizontal adsorption force is realized. Figure 19 The effect of the third step of movement is that the material can be adjusted and turned at the same time. Compared with traditional mechanical equipment, this device is more suitable for the process flow of the new process, and has the advantages of simple structure, high reliability and small space occupation.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
