Description

Technical Field

[0001] This utility model relates to the field of packaging bottle production technology, specifically a packaging bottle gripping and transferring device. Background Technology

[0002] Blow molding of plastic bottles is a widely used plastic processing technology, mainly used to produce hollow containers (such as beverage bottles, daily chemical bottles, and medicine bottles). Its core principle is to heat the plastic raw material to form a preform (preform), then use compressed air to inflate the preform to the shape of the inner wall of the mold, and finally obtain the desired product after cooling.

[0003] After the product is formed and removed, it still needs to undergo sealing pressure testing, vertical load strength testing, or other processing. During these processes, sometimes it is necessary to flip the product bottle from one production line and place it on another. The current practice is to manually flip the product and place it on another production line. However, manually flipping the product is inefficient, labor-intensive, and has a low degree of automation. Moreover, although the product has cooled down after the mold is opened, the temperature is still very high. Directly handling the product by hand can easily leave marks on the product surface and also poses a risk of burns. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2A packaging bottle gripping and transferring device includes a base 1, on which a movable platform 2 and a reciprocating drive mechanism 3 for driving the platform 2 to move horizontally are mounted. A liftable worktable 4 and a lifting mechanism 5 for driving the worktable 4 to rise and fall are mounted on the top surface of the platform 2. A flipping mechanism 6 is mounted on the worktable 4. The flipping mechanism 6 includes two bearing seats 61 disposed opposite each other on the top surface of the worktable 4, a rotating shaft 62 rotatably connected to the two bearing seats 61, and a swing arm 63 with one end perpendicularly connected to the rotating shaft 62. A gripping mechanism 7 is connected to the end of the swing arm 63 away from the rotating shaft 62.

[0025] In this embodiment, a first motor 64 is provided on the top surface of the workbench 4. The output shaft of the first motor 64 is connected to one end of the rotating shaft 62 to drive the rotating shaft 62 to rotate, thereby realizing the flipping of the swing arm 63 relative to the gripping mechanism 7 at one end of the rotating shaft 62. Several support columns (not shown in the figure) are provided on the workbench 4 to support the swing arm 63 when it swings to its limit position. There are two swing arms 63, which are spaced apart on the rotating shaft 62. This utility model does not limit the number of swing arms 63 and gripping mechanism 7, and can be set according to the actual situation.

[0026] This invention uses a gripping mechanism 7 at one end of a swing arm 63 to clamp the bottle mouth and a flipping mechanism 6 to transfer the product from one production line to another. It can replace manual labor to automatically grip and flip the bottle, which is highly automated, improves work efficiency, and avoids leaving marks on the bottle.

[0027] Please see Figure 1 The reciprocating drive mechanism 3 includes a mounting base 31, a screw 32, and a second motor 33. Two mounting bases 31 are arranged opposite each other on the base 1. The two ends of the screw 32 are rotatably connected to the two mounting bases 31 via bearings. The second motor 33 is horizontally mounted on the top surface of the base 1, and its output shaft is connected to one end of the screw 32 to drive its rotation. The bottom of the moving platform 2 is threadedly connected to the screw 32 via a nut sleeve (not shown). When the screw 32 rotates, the nut sleeve drives the moving platform 2 to move axially along the screw 32, thereby achieving horizontal translation of the moving platform 2, which in turn moves the gripping mechanism 7 to the corresponding position to clamp the bottle mouth.

[0028] Please see Figure 1-2The lifting mechanism 5 includes a first cylinder 51, a sleeve 52, and guide rods 53. The first cylinder 51 is fixed to the top surface of the moving platform 2, and one end of the telescopic rod of the first cylinder 51 is connected to the bottom of the worktable 4. In this embodiment, there are four sleeves 52, which are respectively arranged at the four corners of the top surface of the moving platform 2. There are four guide rods 53, which are respectively arranged at the four corners of the worktable 4 and are adapted to the corresponding sleeves 52. The top end of the guide rod 53 is fixedly connected to the worktable 4, and the bottom end of the guide rod 53 is slidably disposed in the sleeve 52. The cooperation between the guide rod 53 and the sleeve 52 has a positioning function, which is used to guide the worktable 4 to rise and fall stably.

[0029] Please see Figure 1 as well as Figure 3 The gripping mechanism 7 includes a gripper body 71 and gripping arms 72. One end of the gripper body 71 is connected to a swing arm 63, and the other end is provided with two opposing hinge shafts 73. There are two gripping arms 72, each hinged to a corresponding hinge shaft 73. The inner surfaces of the two gripping arms 72 facing each other each have a sliding groove 721, and each gripping arm 72 is provided with a gripping assembly 8. The gripping assembly 8 includes a clamping block 81 and an adjusting screw 82. The clamping block 81 is movably disposed within the sliding groove 721, and one end of the adjusting screw 82 passes through the gripping arm 72 and is rotatably connected to the clamping block 81 within the sliding groove 721. Rotating the adjusting screw 82 adjusts the position of the clamping block 81 within the sliding groove 721, increasing or decreasing the distance between the clamping blocks 81 on the two gripping arms 72, thus accommodating gripping operations with bottle openings of different diameters. Please refer to [link to relevant documentation]. Figure 3 The two clamping blocks 81 have clamping grooves 811 adapted to the bottle opening on their inner sides facing each other. The clamping grooves 811 are arc-shaped and the inner walls of the clamping grooves 811 are provided with threads adapted to the bottle opening.

[0030] Please refer to Figure 4 Each clamping arm 72 has an integrally formed swing portion 724 perpendicular to the clamping arm 72 at one end relative to the sliding groove 721, and the hinge shaft 73 is hinged at the connection between the swing portion 724 and the clamping arm 72.

[0031] Please see Figure 4 The gripping mechanism 7 includes a second cylinder 74 disposed inside the gripper body 71. The piston rod of the second cylinder 74 is connected to a pin 75, which is perpendicular to the piston rod of the second cylinder 74. The swing part 724 has an elongated hole 725 adapted to the pin 75. When the swing arm 63 swings, the pin 75 slides within the elongated hole 725. In this embodiment, the piston rod of the second cylinder 74 pushes the swing part 724 to swing around the hinge axis 73 via the pin 75, thereby enabling the swing arm 63 to swing open or close around the hinge axis 73 to release or grip the bottle mouth.

[0032] Please see Figure 3-4The clamping arm 72 has vertically opposite positioning blocks 722 on its top surface near its inner side, extending above the slide groove 721. The top surface of the clamping block 81 has vertically opposite stops 812 that are adapted to the positioning blocks 722. When the two clamping blocks 81 move to their extreme positions, the stops 812 are blocked by the positioning blocks 722. The positioning blocks 722 act as positioning blocks 81, causing the clamping grooves 811 of the two clamping blocks 81 to form corresponding clamping radii. This allows the two clamping blocks 81 to tightly clamp the bottle neck of the corresponding size, preventing the bottle from falling due to loosening of the bottle neck during clamping and improving the stability of bottle transfer. In this embodiment, the clamping radius formed by the two clamping grooves 811 is smallest when the stops 812 are blocked by the positioning blocks 722; the clamping radius is largest when the two clamping blocks 81 retract into the slide groove 721 and contact the inner wall of the slide groove 721.

[0033] Among them, the inner side of the clamping arm 72 is provided with clearance space 723 near the upper and lower walls of the slide groove 721, so as to avoid interference between the bottle mouth and the clamping arm 72 when the clamping radius formed by the two clamping grooves 811 is at its maximum.

[0034] Please see Figure 3-4 At least one set of buffer components 9 is provided between the two clamping arms 72. The buffer component 9 includes a column 91, a buffer block 92, a spring 93, and a limiting block 94. The main body is fixed to the inner side of one of the clamping arms 72. The buffer block 92 is slidably disposed at one end of the column 91, and the spring 93 is sleeved on the column 91. One end of the spring 93 is connected to the inner side of the clamping arm 72, and the other end is connected to the buffer block 92. The limiting block 94 is disposed on the inner side of the other clamping arm 72, and the limiting block 94 is disposed opposite to the buffer block 92. When the two clamping arms 72 are closed, the buffer block 92 abuts against the limiting block 94. In this embodiment, the buffer block 92 plays a role in buffering the impact.

[0035] Please see Figure 1 The workbench 4 is provided with a first conveyor belt 10 and a second conveyor belt 11 on both sides. The top surface of the first conveyor belt 10 is fixed with a fixture 12. The number of fixtures 12 is the same as the number of gripping mechanisms 7. The fixture 12 includes a base 121, a first boss 122 integrally formed on the top surface of the base 121, and a second boss 123 integrally formed on the top surface of the first boss 122. The diameter of the second boss 123 is smaller than that of the first boss 122, and it is used to insert bottle mouths of different diameters. When gripping bottle mouths of different diameters, the gripping radius of the two clamping blocks 81 can be adjusted accordingly by adjusting the lead screw 82.

[0036] The working principle of this packaging bottle gripping and transferring device is as follows: Please refer to... Figure 1-2Before gripping the bottle, the gripping arm 72 of the gripping mechanism 7 is in the open state; then the second motor 33 is started, which drives the screw 32 to rotate, and the moving table 2 moves axially along the screw 32 towards the first conveyor belt 10, so that the gripping arm 72 on the moving table 2 moves to the position of the fixture 12; then the piston rod of the second cylinder 74 pushes the two swing arms 63 to swing and close around the hinge shaft 73 through the pin 75, so that the two clamping blocks 81 clamp the bottle mouth on the fixture 12; then the first cylinder 51 drives the worktable 4 to rise, so that the bottle mouth is disengaged from the fixture 12. After disengaging from fixture 12, the second motor 33 reverses and drives the screw 32 to rotate, and the moving table 2 moves along the screw 32 axis and resets; then the first motor 64 drives the rotating shaft 62 to rotate, causing the clamping arm 72 at one end of the swing arm 63 to swing above the second conveyor belt 11; finally, the piston rod of the second cylinder 74 pushes the two swing arms 63 to swing open around the hinge shaft 73 through the pin shaft 75, so that the two clamping blocks 81 release the bottle mouth, and the bottle can be placed on the second conveyor belt 11, thus completing the transfer of the bottle. By repeating this cycle, bottles can be transported between different production lines.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
