Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a concealed line-changing structure for packaging barrels. Background Technology

[0002] In the packaging and production process of lubricating oil and coolant, the packaging barrels need to be transferred between different conveyor lines from an empty state to a full state after filling. Efficient, stable line-changing technology that does not interfere with the normal transport of packaging barrels is crucial for improving production efficiency and reducing production costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a concealed conveyor system for packaging drums, enabling rapid and efficient transfer of packaging drums between empty drum conveyor lines, liquid filling lines, and full drum conveyor lines without interfering with the on-line transport of the drums. The technical solution adopted by this utility model is as follows: A concealed line-changing structure for packaging drums includes: An empty barrel conveyor line has several empty barrel docking sections and empty barrel spacing sections arranged alternately in the front-to-back direction, and a first line changing trough is formed between adjacent empty barrel docking sections and empty barrel spacing sections. The injection line has several injection docking parts arranged at intervals along the front-to-back direction, and the front and back sides of the injection docking parts respectively form a second line changing groove. The full barrel conveying line has several third line changing grooves arranged at intervals along the front-to-back direction. Several empty barrel docking parts and several liquid filling docking parts correspond one-to-one along the left-to-right direction. The left ends of several first line changing grooves, several second line changing grooves, and several third line changing grooves correspond one-to-one. Replacement components, including: The first linear cylinder is fixedly installed in the left-right direction; The first connecting rod is connected to the output end of the first linear cylinder and is arranged to slide in the left-right direction; Several second connecting rods are respectively arranged below the liquid injection docking part; The second linear cylinder and the lever: each second link is provided with two second linear cylinders spaced apart in the left and right directions, and any second linear cylinder is arranged in the vertical direction and its output end is connected to the lever; In this configuration, the two levers on any of the second connecting rods are directly below the first and second switching slots.

[0004] Furthermore, it also includes: Several connecting parts are alternately arranged with several liquid injection docking parts along the front-back direction. The right end of any one of the connecting parts is connected to the empty barrel interval and the left end is connected to the full barrel conveying line.

[0005] Furthermore, a bucket-shifting section is provided connected to the empty bucket conveyor line and / or the full bucket conveyor line, the bucket-shifting section comprising: Several forks; A conveyor chain, on which several of the aforementioned forks are spaced apart, the conveyor chain driving the several forks to move backward in sequence.

[0006] Advantages of this utility model: By using the lifting and lowering action of the lever in the line changing component, in conjunction with the left and right movement of the lever driven by the first linear cylinder, the synchronous transfer action of empty barrels on the empty barrel conveyor line to the liquid filling line and full barrels on the liquid filling line to the full barrel conveyor line is completed. When the full barrel conveyor line is conveying full barrels backward, empty barrels can be transferred to the empty barrel conveyor line in sequence, reducing waiting time. After the packaging drum transfer is completed, the lever descends and hides below the plane where the liquid injection dock is located, without affecting or interfering with the conveying of the packaging drum on each line.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0011] Please see the appendix Figure 1 and attached Figure 2 This application proposes a concealed line-changing structure for packaging drums, comprising: The empty barrel conveyor line 100 has several empty barrel docking parts 110 and empty barrel spacing parts 120 arranged alternately in the front-back direction, and a first line changing groove 130 is formed between adjacent empty barrel docking parts 110 and empty barrel spacing parts 120. The injection line 200 has several injection docking parts 210 arranged at intervals along the front-to-back direction, and the front and rear sides of the injection docking parts respectively form a second line changing groove 230. The full barrel conveying line 300 has several third line changing grooves 310 arranged at intervals along the front-to-back direction. Several empty barrel docking parts 110 and several liquid filling docking parts 210 correspond one-to-one in the left-to-right direction. The left ends of several first line changing grooves 130, several second line changing grooves 230 and several third line changing grooves 310 correspond one-to-one. Replacement cable 400, including: The first linear cylinder 410 is fixedly installed in the left-right direction; The first connecting rod 420 is connected to the output end of the first linear cylinder 410 and is slidably arranged in the left-right direction; Several second connecting rods 430 are respectively arranged below the liquid injection docking part 210; The second linear cylinder 440 and the lever 450 are provided. Each second link 430 is provided with two second linear cylinders 440 at intervals along the left and right directions. Any second linear cylinder 440 is arranged in the vertical direction and its output end is connected to the lever 450. In this configuration, the two levers 450 on any of the second connecting rods 430 are directly below the first switching slot 130 and the second switching slot 230.

[0012] The conveying direction of the packaging drums is as follows: Figure 1As shown, empty barrels enter the empty barrel conveyor line 100 sequentially from front to back, eventually stopping at the empty barrel docking section 110, where one empty barrel corresponds to two first line changing slots 130; empty barrels on the liquid filling line 200 stop at the liquid filling docking section 210, corresponding to the liquid outlet, and are filled with liquid to become full barrels, where one full barrel corresponds to two second line changing slots 230; on the full barrel conveyor line 300, one full barrel corresponds to two third line changing slots 310, and full barrels are sequentially conveyed from front to back to the next station; under normal conditions, the lever 450 descends, without affecting the conveying of empty barrels on the empty barrel conveyor line 100, and without interfering with the movement trajectory of the empty barrels; packaging barrels During line changing, several second linear cylinders 440 simultaneously actuate, raising several levers 450. At this time, the cylindrical surface of a packaging drum (empty or full) corresponds to two levers 450. The two levers 450 are symmetrical about the axis of the packaging drum, which improves the stability of the drum's movement and is more suitable for cylindrical packaging drums. After the levers 450 are raised to their positions, the first linear cylinder 410 actuates, driving the first connecting rod 420, the second connecting rod 430, and the levers 450 to move synchronously to the left. The lever 450 corresponding to the empty drum slides from the first line changing groove 130 to the second line changing groove 230, pushing the empty drum from the empty drum docking part 110. The barrel is transferred to the liquid injection docking section 210, and the lever 450 corresponding to the full barrel slides from the second line changing groove 230 to the third line changing groove 310, pushing the full barrel from the liquid injection docking section 210 to the full barrel conveying line 300. After the line changing is completed, the second linear cylinder 440 and the first linear cylinder 410 are reset respectively, and the empty barrel conveying and full barrel conveying processes can be carried out simultaneously, saving waiting time.

[0013] As is easily understood, the liquid injection docking section 210 is supported by a bracket or other components (not shown in the figure). The empty barrel conveyor line 100 and the full barrel conveyor line 300 can also be installed on the same bracket. The bracket adopts a hollow design to hide the line changing component 400. The first linear cylinder 410 is fixedly installed. The first connecting rod 420 and the second connecting rod 430 can be provided with separate brackets or other support components, or they can use the same bracket as the liquid injection docking section 210. However, the horizontal movement of the first connecting rod 420 needs to be considered. Note that a slider or slide rail should be provided between the bracket and the first connecting rod 420.

[0014] To prevent the packaging drum from falling off, fill the gaps between the lines and connect the three lines together. Please refer to the appendix. Figure 1 This application also includes a plurality of connecting parts 220, which are alternately arranged with a plurality of liquid injection docking parts 210 along the front-back direction. The right end of any of the connecting parts 220 is connected to the empty barrel interval part 120 and the left end is connected to the full barrel conveying line 300.

[0015] Specifically, the connecting part 220 is a thin metal plate, with connecting ears welded to its left and right ends respectively. The connecting ear at the right end is connected to the empty bucket conveyor line 110 by bolts, and the connecting ear at the left end is connected to the full bucket conveyor line 300 by rivets. The connecting ears compensate for the gap error between the left and right ends of the connecting part 220, so that even if the gaps on the left and right sides are different, it will not affect the installation of the connecting part 220.

[0016] To facilitate the conveying of packaging barrels on the empty barrel conveyor line 100 and the full barrel conveyor line 300, in one embodiment, a barrel-shifting part is provided connecting to the empty barrel conveyor line 100 and / or the full barrel conveyor line 300. The barrel-shifting part includes: A plurality of shift forks 500; a conveyor chain 600, wherein the plurality of shift forks 500 are spaced apart on the conveyor chain 600, and the conveyor chain 600 drives the plurality of shift forks 500 to move backward in sequence.

[0017] In one specific embodiment, the conveyor chain 600 is arranged to rotate back and forth along a vertical line. Taking the empty bucket conveyor line 100 as an example, the fork 500 moves from front to back on the upper side of the empty bucket conveyor line 100, and after rotating, moves from back to front on the lower side of the empty bucket conveyor line 100, continuously pushing the empty buckets placed at the front entrance of the empty bucket conveyor line 100 backward to the respective empty bucket docking parts 110.

[0018] In another specific embodiment, the conveyor chain is arranged to rotate back and forth along the horizontal front. Taking the full barrel conveyor line 300 as an example, the shift fork 500 moves from front to back on the upper side of the full barrel conveyor line 300, and rotates only from back to front on the left side of the full barrel conveyor line 300, which moves the full barrel that has been moved from the injection line 200 to the next station.

[0019] In addition, it should be noted that the number of empty barrel docking parts 110 and liquid injection docking parts 210 in this application are set as needed, and there is no specific quantity requirement.

[0020] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
