Description

Technical Field

[0001] The invention relates to a filling device in the machinery industry, in particular to a three-station conveying system for square barrels. Background Art

[0002] During the filling process, the material barrel is transported to the filling station, filled with material, and then output. In order to improve work efficiency, the existing filling machine generally adopts a three-station conveying system for empty barrel input, material barrel filling, and loaded barrel output to transport the three processes of material barrels. The three stations need to work at the same time, cannot interfere with each other, and need to coordinate with each other.

[0003] Chinese invention patent No. CN 102311080 B discloses a "filling machine", which includes an upper empty barrel conveyor, a capping machine, a filling system and an oil storage system. The upper empty barrel conveyor of the barrel separator is connected to arrange the empty barrels in order and separate them for output; the longitudinal empty barrel conveyor is connected to the barrel separator to convey the empty barrels along the longitudinal axis; one side of the transverse conveyor is connected in parallel with the end of the longitudinal empty barrel conveyor, and a filling station is provided on it for conveying the empty barrels to the filling station and outputting the filled loading barrels laterally; the longitudinal loading barrel conveyor is connected in parallel to the other side of the conveyor to output the loading barrels along the longitudinal axis. The technical solution disclosed in the patent uses a barrel separator to separate the circular barrels adjacent to each other and then convey them by a fork. However, for square barrels, the contact surface between the barrels increases and the interval between them is greatly reduced, so it is difficult for such a barrel separator to separate square empty barrels.

[0004] Chinese utility model patent No. CN 203652642 U discloses a three-station horizontal shifting conveying system, which includes a fork-type longitudinal barrel inlet conveying mechanism, a horizontal barrel shifting conveying mechanism and a roller-type longitudinal barrel outlet conveying mechanism. The technical solution disclosed in the patent also has the disadvantage that it is difficult to split the empty barrels.

[0005] The inventor has observed for a long time that the lateral conveying devices provided by the above-mentioned prior art are all arranged at the bottom of the barrel, and the structure below the filling station is complicated. When there are splashes or leaks, the lateral conveying devices need to be cleaned, which undoubtedly increases the workload of equipment maintenance. For materials that are easy to crystallize, have high viscosity, and are highly corrosive, the disadvantages of this structural technical solution are particularly obvious. At the same time, the above-mentioned prior art solution adopts the positioning of the conveying device, which can only position the material barrel of the filling station, but cannot achieve the precise positioning of a single material barrel. When there are many filling stations of the filling machine, it is difficult to ensure the precise positioning of all material barrels at the same time. Summary of the invention

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a three-station conveying system for square barrels, which realizes the splitting of empty barrels through the differential speed of rollers, thereby simplifying the barrel separation process; realizes precise positioning of each material barrel through a positioning mechanism; and arranges the lateral conveying mechanism on the side of the material barrel for easy maintenance and cleaning.

[0034] In addition to the embodiments described below, the present invention may have other embodiments or be implemented in different ways. Therefore, it should be understood that the present invention is not limited to the details of the component structures described in the following description or shown in the accompanying drawings. The embodiments herein cannot be used as a limitation on the scope of protection of the claims.

[0035] The technical solution provided by the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Unless otherwise specified, the term "horizontal" used in this specification represents the horizontal direction of the conveyor. The term "three-station conveying" means the horizontal movement of the empty barrel by the horizontal barrel pushing device, the longitudinal conveying of the empty barrel by the empty barrel conveyor, and the longitudinal conveying of the loaded barrel by the loaded barrel conveyor.

[0036] Below Figure 1 Taking the six heads or six filling stations 400 shown as an example, a three-station conveying system for square barrels provided by the present invention is described in detail. The system comprises an empty barrel conveyor 100 and a loading barrel conveyor 200 composed of rollers arranged in parallel on the same horizontal plane. The two conveyors are longitudinally parallel and on the same plane, with a spacing required for filling. The empty barrel conveyor 100 and the loading barrel conveyor 200 are provided with a barrel pushing device 300 for horizontally pushing upward. Not shown in the figure, the empty barrel conveyor 100 and the loading barrel conveyor 200 shown are respectively provided with a lifting mechanism for lifting the two conveyors.

[0037] like Figure 2 and Figure 3 As shown, the empty barrel conveyor 100 is a conveyor composed of rollers arranged at equal distances on the same horizontal plane, and then the empty barrels 500 to be filled are input through the longitudinal transmission on the belt; the rollers on the empty barrel conveyor 100 are of two specifications, the fourth to the seventh rollers starting from one end of the power shaft are large-diameter rollers 120, and the outer sides of the fourth and seventh rollers are small-diameter rollers 140 respectively. The rollers of the two specifications share the same power group 110, and the upper surfaces of all rollers are in the same horizontal plane; a barrel dividing mechanism 130 is arranged between the second and third large-diameter rollers 120; the empty barrel conveyor 100 is arranged with six sets of equal-height limit mechanisms on the inner side of the inner side of the power group 110 for longitudinal positioning of the empty barrels 500, of which five sets are powered limit mechanisms 150, and the last set is a non-powered limit mechanism 160, and the total number of limit mechanisms is the same as the number of filling stations 400 of the filling machine.

[0038] The power group 110 arranged below the empty barrel conveyor 100 is composed of a motor 111, a driving sprocket 112, a driving chain 113, etc. The driving chain 113 connects the sprockets of all rollers to drive the rollers to rotate.

[0039] The barrel separation mechanism 130 located on the inner side of the power group is arranged below the empty barrel conveyor 100, and is composed of a cylinder 131, a barrel separation plate 132 arranged perpendicular to the belt transversely, etc. The cylinder 131 drives the barrel separation plate 132 to move up and down in the transverse direction of the belt to split or pause the empty barrels 500.

[0040] The structure and working principle of the powered limiting mechanism 150 are similar to those of the barrel dividing mechanism 130 .

[0041] In addition, the barrel dividing mechanism 130 and the powered limiting mechanism 150 may also be arranged on the side of the empty barrel conveyor 100 .

[0042] like Figure 4 As shown, the transmission mode of the loading bucket conveyor 200 is similar to that of the empty bucket conveyor 100 , and the roller 220 is driven to rotate by a power group 210 arranged at one end of the conveyor to output the filled loading bucket 600 .

[0043] like Figure 5 and Figure 6As shown, the transverse barrel pushing device 300 arranged on the outside of the empty barrel conveyor 100 includes a transverse pushing mechanism 310, a transverse pulling back mechanism 320 and a positioning mechanism 330; the transverse pushing mechanism 310 includes a motor 311 that provides driving force, the motor 311 is connected to a lead screw 313 through a conveyor belt 312, and a nut 314 on the lead screw 313 is fixed on a push frame 315, and the motor 311 drives the lead screw 313 to rotate through the conveyor belt 312, so that the push frame 315 moves horizontally; slide rail groups 316 are arranged on both sides above the push frame 315, and six groups of pulling back mechanisms 320 and positioning mechanisms 330 are arranged on the side of the push frame 315; the pulling back mechanism 320 includes a cylinder 321, the cylinder 321 is fixed under the push frame 315, and a flat plate 322 is fixed on it, and a plurality of magnets 323 or suction cups are embedded on the flat plate 322; the positioning mechanism 330 is fixed on the side of the push frame 315, and each group has two pieces, which are arranged on both sides of the pulling back mechanism 320. The push frame 315 is a support frame without walls but with an upper cover, which is shaped like a football field gate. Parallel slide rails 316 are respectively provided on the tops of the left and right sides of the support frame to move the push frame 315 in the lateral direction of the empty barrel conveyor 100.

[0044] In addition, the propulsion mechanism 310 can also be driven by a cylinder; the magnet 323 on the pulling back mechanism 320 is used for iron square barrels, and for non-iron barrels, a suction cup is required instead.

[0045] The working process of the three-station conveying system for square barrels provided by the present invention is described in detail below in the form of an embodiment in conjunction with the accompanying drawings.

[0046] Example:

[0047] like Figure 2 As shown, the empty barrel 500 is input in the direction of the power group 110 at the head end of the conveyor belt to the non-powered limiting mechanism 160 at the end in the direction shown in the figure. Since the diameter of the roller 120 is larger than that of the roller 140, the linear speed of the large-diameter roller 120 is larger than that of the small-diameter roller 140 at the same rotation speed. Therefore, the empty barrel 500 will accelerate when it is transported to the belt section of the large-diameter roller 120, so that the empty barrels 500 transported on the conveyor can be transported at different speeds or a certain distance can be formed between them. When six empty barrels 500 pass through the barrel separation mechanism 130, the barrel separation mechanism 130 acts to block the seventh empty barrel 500. The six empty barrels that pass through continue to be transported forward, and the first empty barrel 500 reaches the positioning position of the non-powered limiting mechanism 160. After the remaining empty barrels 500 reach a certain position, the corresponding belt power limiting mechanism 150 acts in turn to position them. The barrel plate 132 may be made of stainless steel having the following components by mass percentage: Ni 18.0, Co 8.5, Mn 3.3, Ti 0.2 and Al 0.1, and a yield strength MPa (ksi) of 1400 (200).

[0048] like Figure 6 and Figure 7 As shown, when the empty barrel 500 enters the predetermined position of the empty barrel conveyor 100 and the loading barrel 600 is filled, the push frame 315 pushes the empty barrel 500 to move horizontally under the drive of the motor 311 until the empty barrel 500 contacts the loading barrel 600, and then pushes the loading barrel 600 to move simultaneously. While the empty barrel 500 moves, the positioning mechanism 330 limits the longitudinal deviation of the empty barrel 500. When the loading barrel 600 reaches the predetermined position of the loading barrel conveyor 200, the loading barrel 600 moves horizontally. Figure 4 The longitudinal direction shown is output from the conveyor belt at one end of the power group 210. At the same time, the pull-back mechanism 320 is activated, the cylinder 321 extends, and the drive plate 322 moves until it is close to the barrel wall of the empty barrel 500. At this time, the magnet 323 or the suction cup sucks the empty barrel 500. The push rack 315 returns under the drive of the motor 311, and the magnet 323 or the suction cup attracts the empty barrel 500 and returns at the same time. When the push rack 315 moves to a certain position and pauses for a while, the cylinder 321 retracts, and due to the obstruction of the positioning mechanism 330, the magnet 323 or the suction cup separates from the empty barrel 500, and the positioning mechanism 330 completes the positioning of the empty barrel 500. At this time, the empty barrel remains in the filling station 400 for filling.

[0049] When the push rack 315 continues to return until it is reset, the empty barrel conveyor 100 waits for the next batch of empty barrels 500 to enter, and the cycle continues.

[0050] It should be noted that, if encountering special circumstances such as damage to the filling head, filling position failure, etc., which causes one or some filling stations 400 to be unable to fill, the barrel dividing mechanism 130 of the present invention can select the number of empty barrels 500 to be released each time according to the actual situation, and through the corresponding action of the power limiting mechanism 150, the faulty filling station 400 is free of barrels, thereby ensuring the reliability of filling.

[0051] The above embodiments show that the three-station conveying system for square barrels of the present invention realizes the splitting of empty barrels through the differential speed of rollers, which simplifies the barrel separation process; the precise positioning of each material barrel is achieved through the positioning mechanism; and the lateral conveying mechanism is arranged on the side of the material barrel for easy maintenance and cleaning.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
