Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a variable pitch steering mechanism for a blister box transfer system. Background Technology

[0002] With the continuous progress of society, the packaging industry has developed rapidly. Transfer systems are a crucial component of the packaging industry. A transfer system is an important device for moving products from one location to another for processing. In the packaging process, long-distance single-transfer transport places high demands on space, and processors typically consider using different transfer systems for processing. Current transfer systems usually involve separate, independently set moving and turning processes, resulting in high installation costs and significant space requirements. Currently, there is no blister pack transfer mechanism that can simultaneously achieve turning and distance adjustment functions, making seamless integration with instrument box blister packing machines impossible. This leads to the blister packs output by the instrument box blister packing machine being unable to match the direction and spacing of subsequent servo-driven conveyor lines, thus affecting the smooth operation of subsequent processes and creating a docking problem between the instrument box blister packing machine and the transfer machine. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] In this application, the rotary cylinder 8, control valve 4, suction cup 12, and split cylinder 2 are purchased directly from the market according to specific models and then matched and installed for use.

[0019] See Figure 1-4 The diagram shows a variable-pitch steering mechanism for a blister pack transfer system, comprising a vertically mounted fixed plate 1, a middle transfer component mounted on the lower end of the fixed plate 1, and two vertically mounted support cylinders 2 on either side of the fixed plate 1, with end transfer components mounted on the telescopic ends of the support cylinders 2; protective covers 3 are fixed to the upper ends of the fixed plate 1 via corner brackets, a control valve 4 is mounted in the middle of the upper end of the protective cover 3, and a guide rod 5 is parallel to the lower part of the protective cover 3, passing vertically through the fixed plate 1, with both ends of the guide rod 5 connected by end plates 6; the upper part of the end transfer component is movably mounted on the guide rod 5; both the middle and end transfer components include a sliding plate 7, the upper part of the sliding plate 7 is sleeved on the guide rod 5, a rotary cylinder 8 is mounted on the lower part of the sliding plate 7, a connecting arm 9 is fixed to the output end of the rotary cylinder 8, a connecting block 10 is mounted on the lower end of the connecting arm 9, a connecting rod 11 passes through the middle of the connecting block 10, and a suction cup 12 is mounted on the end of the connecting rod 11.

[0020] The connecting rod 11 has a sleeve 13 at its end, which holds a suction cup 12 in the middle. An air source is connected to one side of the sleeve 13, and the suction cup 12 adsorbs the blister pack 14 at its lower part. Locking plates 15 are installed at the ends of the guide rods 5, and anti-collision pads 16 are provided on the side of the locking plates 15 opposite to the sliding plate 7. Positioning plates 17 are installed at both ends of the protective cover 3. A fixing block 18 is provided at the lower part of the rotary cylinder 8, and a rotating shaft 19 is installed at the lower end of the fixing block 18. One end of the rotating shaft 19 is hinged to the lower end of the fixing block 18, and the other end is hinged to the upper part of the suction cup 12. A split-support cylinder 2 is vertically inserted and fixedly installed on the fixing plate 1. One end of the split-support cylinder 2 extends through the fixing plate 1, and the other end extends out of the fixing plate 1 and connects to the end transfer assembly.

[0021] The operating principle of the variable pitch steering mechanism used in this blister pack transfer system is as follows:

[0022] First, the operator controls the overall blister pack transfer system to descend using a variable-pitch steering mechanism via an external controller. The blister packs 14 on the first conveyor belt are then attracted by suction cups 12. The system is then moved to one side above the second conveyor belt. During this movement, the end transfer components simultaneously change pitch and steer, and the middle transfer components also steer. The end transfer components operate as follows: the extension of the supporting cylinder 2 pushes the sliding plate 7 outwards, simultaneously controlling the operation of the corresponding rotary cylinder 8. The rotary cylinder 8 rotates the connecting arm 9, causing the connecting block 10 to rotate along with the connecting rod 11 by 90°. This rotates the originally horizontally placed blister packs 14 onto the second conveyor belt, ensuring proper spacing between the blister packs 14 and preventing stacking. The middle transfer components operate as follows: the corresponding rotary cylinder 8 rotates, causing the connecting arm 9 to rotate, which in turn rotates the connecting block 10 along with the connecting rod 11 by 90°, thus changing the orientation of the blister packs 14.

[0023] The blister pack transfer system of this application uses a variable-pitch steering mechanism to simultaneously grasp six blister packs (arranged in a 2×3 pattern) from the instrument box tray machine and transfer them to the servo-station conveyor line. Given the difference in discharge direction and spacing between the instrument box tray machine and the servo-station conveyor line, the mechanism rises to a certain height after the suction cups grasp the blister pack 14, and then completes a steering action while moving towards the servo-station conveyor line. When the blister pack 14 is moved above the servo-station conveyor line, the mechanism actively adjusts the spacing according to the station spacing on the servo-station conveyor line and accurately places the blister pack 14 under servo control.

[0024] This application includes a suction cup assembly capable of simultaneously gripping six (arranged in a 2×3) blister packs 14. The suction cup assembly is connected to a transfer mechanism with lifting and translational drive functions. The transfer mechanism is equipped with a steering drive component. After the suction cup assembly grips the blister pack and lifts it to a preset height, during its translational movement towards the servo station conveyor line, the steering drive component guides the suction cup assembly to complete a steering action, ensuring that the output direction of the blister pack is consistent with the conveying direction of the servo station conveyor line.

[0025] Furthermore, the installation spacing of each set of suction cups in the suction cup assembly can be adjusted by a variable pitch drive device. When the blister box 14 is moved above the servo station conveyor line, the variable pitch drive device will synchronously adjust the spacing of each set of suction cups according to the station spacing on the conveyor line to ensure that the arrangement spacing of the blister box is consistent with the station spacing.

[0026] Through this structure and control method, this application can effectively overcome the limitations of the blister box 14 in terms of output direction and spacing, and achieve seamless connection between the instrument box blister tray machine and the servo station conveyor line, thereby ensuring the continuity and smooth operation of subsequent processes.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
