[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] See also Figures 1 to 4 , a preform conveying mechanism, comprising a frame 1, a vertical slide 2 fixed on the frame 1, a preform receiving assembly 3 arranged on one side of the vertical slide 2, a reversing assembly 4 obliquely arranged below the vertical slide 2, and a conveying belt 5 located below the reversing slide;

[0037] An opening 21 into which a preform can be inserted is provided at the upper end of the vertical chute 2. Through the opening 21, the preform 9 can be vertically inserted into the vertical chute 2. The preform receiving assembly 3 includes a plurality of preform receiving plates 31 and a driving member 32 for driving the plurality of preform receiving plates 31 to extend into or withdraw from the vertical chute 2. The plurality of preform receiving plates 31 are located on one side of the vertical chute 2. The preform receiving plates 31 are inserted into the vertical chute 2 by the driving member 32 so that the preform receiving plates 31 can support the preform. In this embodiment, the plurality of preform receiving plates 31 are arranged in the 6 o'clock direction or the 12 o'clock direction of the vertical chute 2.

[0038] The reversing assembly 4 includes a plurality of square frames 41 and a plurality of first limiting strips 42. The plurality of square frames 41 are arranged in sequence from top to bottom. The square frame 41 at the highest position is the first square frame 411, and the square frame 41 at the lowest position is the second square frame 412. The inner hole of the first square frame 411 is aligned with the outlet of the vertical chute 2 to receive the preform 9 output from the vertical chute 2. The inner hole of the second square frame 412 is docked with the inlet of the conveying belt 5. The plurality of first limiting strips 42 are arranged through the plurality of square frames to form a reversing chute through which the preform can pass. The preform 9 output from the vertical chute 2 enters the reversing chute. The length direction of the first square frame 411 is perpendicular to the length direction of the second square frame 412. From the first square frame 411 to the second square frame 412, the angle between the square frame 41 and the horizontal plane gradually decreases from top to bottom. After the preform 9 enters the first square frame 411, it slides along the reversing chute to the second square frame 412. In this embodiment, when the preform 9 enters the first square frame 411, it is placed in the X direction, that is, the length direction of the first square frame 411 is the X direction. When the preform 9 is output from the second square frame 412, it is placed in the Y direction, that is, the length direction of the second square frame 412 is the Y direction. The preform 9 passing through the reversing chute realizes a 90° reversal, and the reversed preform 9 enters the conveying belt 5.

[0039] During use, the preform picking manipulator takes out the injection-molded preform 9 from inside the injection molding machine, moves to the upper part of the vertical chute 2, and then the preform picking manipulator vertically descends so that the preform 9 is inserted into the vertical chute 2 through the opening 21 until all the preforms 9 are located inside the vertical chute 2. Subsequently, the driving member 32 acts to make the plurality of preform receiving plates 31 extend into the vertical chute 2. Then, the preform picking manipulator releases the preform 9 and returns to the origin to wait for the preform forming signal of the injection molding machine. The preform 9 is supported by the preform receiving plates 31, and each preform receiving plate 31 supports one preform 9. Then, the driving member 32 acts to make the plurality of preform receiving plates 31 withdraw from the vertical chute 2. The preform 9 slides along the vertical chute 2 into the reversing chute, and after being reversed by the reversing chute, it enters the conveying belt 5 and is output. By cooperating with the vertical chute 2 and the reversing assembly 4 to receive the preform 9, the direct dropping of the preform 9 is avoided, which plays a role in protecting the preform 9.

[0040] Since the length direction of the first square box 411 is perpendicular to the length direction of the second square box 412, from the first square box 411 to the second square box 412, the angle between the square box 41 and the horizontal plane gradually decreases from top to bottom. The preform 9 passing through the commutation slideway can achieve a 90° commutation. The commutation assembly 4 has a simple structure, can simplify the equipment, and thus reduce the manufacturing cost and maintenance cost of the equipment; actually, the commutation assembly 4 should be fixed on the frame 1, or a support member (not shown in the figure) is provided on the frame 1 to support the commutation assembly 4.

[0041] The commutation assembly 4 is inclined and arranged below the vertical slideway 2, and the commutation slideway is also inclined, which can guide the preform 9 obliquely and slow down the sliding speed of the preform 9 in the commutation slideway, so as to reduce the collision between the preforms 9 and avoid damage to the preforms 9.

[0042] Preferably, the first square box 411 is horizontally arranged, and the angle between the second square box 412 and the horizontal plane is 45° - 90°. The second square box 412 is inclined relative to the horizontal plane, so that the preform 9 output from the commutation slideway can enter the conveying belt 5 obliquely instead of falling vertically into the conveying belt 5, reducing the impact force when the preform 9 enters the conveying belt 5 and playing a role in protecting the preform 9.

[0043] Specifically, refer to Figure 2 and Figure 4 , the vertical slideway 2 includes a mounting plate 22 fixed on the frame 1, a plurality of vertically arranged second limiting strips 23 and a plurality of C-shaped members 24 arranged vertically. A through hole 221 for the preform to pass through is provided on the mounting plate 22. The lower ends of the plurality of second limiting strips 23 are all fixed in the through hole 221. The plurality of second limiting strips 23 enclose a falling channel for the preform to pass through. The plurality of C-shaped members 24 are clamped on the outside of the falling channel. The embryo receiving plates 31 are arranged in one-to-one correspondence below the C-shaped members 24. When the embryo picking manipulator descends vertically and inserts the preform 9 into the vertical slideway 2 from the opening 21, the embryo picking manipulator aligns the preform 9 with the position of the C-shaped member 24, so that the C-shaped member 24 limits the preform 9. Subsequently, the driving member 32 acts to make the plurality of embryo receiving plates 31 extend into the vertical slideway 2 and be located below the C-shaped member 24 to support the preform 9. Each embryo receiving plate 31 supports one preform 9. Then the driving member 32 acts to make the plurality of embryo receiving plates 31 withdraw from the vertical slideway 2, and the preform 9 slides along the vertical slideway 2 into the commutation slideway, and after commutation through the commutation slideway, it enters the conveying belt 5 and is output.

[0044] Specifically, the driving member 32 is a cylinder, and each embryo plate 31 is connected to a cylinder. By controlling each cylinder individually, the embryo plates 31 can be controlled to be pulled out of the vertical slide 2 one by one. The embryo removal robot descends vertically to insert the bottle preform 9 into the vertical slide 2 from the opening 21, and then all cylinders are simultaneously operated to make multiple embryo plates 31 simultaneously extend into the vertical slide 2 and be located below the C-shaped member 24 to support the bottle preform 9. Each embryo plate 31 supports one bottle preform 9, and then multiple cylinders are operated from bottom to top in sequence to make multiple embryo plates 31 be pulled out of the vertical slide 2 from bottom to top in sequence, so that the bottle preforms 9 slide into the reversing slide one by one along the vertical slide 2. The speed at which the bottle preforms 9 enter the conveyor belt 5 through the reversing slide is controlled, so that the bottle preforms 9 can enter the conveyor belt 5 at equal distances.

[0045] Preferably, see Figure 5 The conveyor belt 5 is provided with a plurality of baffles 51, and the area between two adjacent baffles 51 is used as a space for accommodating a single preform. The arrangement of the baffles 51 enables the preforms 9 entering the conveyor belt 5 to be regularly arranged, which is beneficial for subsequent steam framing. Moreover, the baffles 51 separate the preforms 9, which can prevent the preforms 9 from colliding with each other on the conveyor belt 5, thereby protecting the appearance of the preforms 9.

[0046] Preferably, see Figures 1 to 4 , two vertical slides 2, embryo receiving components 3, reversing components 4 and conveying belts 5 are respectively provided, the two vertical slides 2 are arranged side by side, the two embryo receiving components 3 are arranged in mirror image on the opposite sides of the two vertical slides 2, the two reversing components 4 are arranged one by one below the two vertical slides 2 and the two reversing components 4 are arranged in mirror image, and the entrances of the two conveying belts 5 are respectively connected to the inner holes of the second square frame 412 of the two reversing components 4. The existing embryo retrieval robot can take out double-row bottle embryos 9 at a time, so two vertical slides 2, embryo receiving components 3, reversing components 4 and conveying belts 5 are respectively provided, which can simultaneously receive, reverse and convey double-row bottle embryos 9, thereby improving production efficiency. In fact, the number of vertical slides 2, embryo receiving components 3, reversing components 4 and conveying belts 5 is not limited to two, and more can be provided, depending on the number of rows of embryos taken by the embryo retrieval robot at a time.

The framing robot 6 is located above the conveying belt 5, and the cage 7 is placed on the side of the conveying belt 5 away from the reversing component 4. The framing robot 6 grabs the preform 9 from the conveying belt 5 and moves the preform 9 to the cage 7. When the preform 9 is transported on the conveying belt 5, the framing robot 6 grabs the preform 9 on the conveying belt 5 and transfers it to the cage 7 to realize automatic framing.

[0049] For details, seeFigure 7 The framing robot 6 includes a robot arm 61, a fixed plate 62, a plurality of vacuum suction cups 63 and a vacuum generator 64.

The vacuum generator 64 is connected to the plurality of vacuum suction cups 63 through a plurality of pipelines (not shown in the figure). The vacuum suction cups 63 can suck up the preforms 9. The vacuum generator 64 provides negative pressure for the vacuum suction cups 63. The plurality of preforms 9 are sucked up by the plurality of vacuum suction cups 63 at the same time. Then, the plurality of preforms 9 are moved into the box cage 7 by moving the robot arm 61. Then, the vacuum generator 64 stops generating negative pressure, the vacuum suction cups 63 stop sucking the preforms 9, and the preforms 9 are left in the box cage 7. The robot arm 61 drives the fixed plate 62 to reset back to the top of the conveyor belt 5.

The X-direction motion mechanism 82 is installed on the frame 81. By setting the X-direction motion mechanism 82, the Y-direction motion mechanism 83, and the Z-direction motion mechanism 84, the framing robot 6 can move in the three directions of X, Y, and Z to achieve three-axis movement, so that the framing robot 6 can frame more flexibly.
