[0032] The following combines the accompanying drawings to illustrate the specific embodiments of the present utility model.

[0033] As Figure 1 shown, a spacing and feeding mechanism in this embodiment includes a loading plate 2. A through material groove 20 is opened on the loading plate 2. One end of the material groove 20 is connected to an external feeding mechanism, and the closely arranged tubular products 10 are conveyed into the material groove 20 by the external feeding mechanism. A clamping member 5 is installed at the other end of the material groove 20; a spacing mechanism 6 is installed above the loading plate 2. The spacing mechanism 6 spaces the tubular products 10 to a preset spacing and sequentially transfers them to the clamping member 5; a lateral blocking mechanism 8 is installed on the bottom surface of the loading plate 2.

[0034] During use, the spacing mechanism 6 spaces the tubular products 10 in the chute 20 according to the setting, achieving spaced feeding during the feeding of the tubular products 10, with good stability and high reliability. At the same time, combined with the lateral blocking mechanism 8, the closely arranged tubular products 10 are blocked, especially the blocking switching for the foremost tubular product 10 in the close arrangement, ensuring the spacing operation of the spacing mechanism 6 and facilitating subsequent clamping by the clamping member 5 and subsequent detection and other operations in sequence.

[0035] In this embodiment, the loading plate 2 can be composed of a plurality of plates arranged at intervals, and the intervals form the chute 20.

[0036] In this embodiment, the external loading mechanism can adopt the structural form of a vibrating bowl combined with a linear vibrator to realize the automatic arrangement of the tubular products 10 and gradually convey them into the chute 20 of the loading plate 2. Of course, in actual use, an external loading mechanism with other structural forms can also be adopted as long as it can realize the automatic arrangement of the tubular products 10 and continuously feed them into the chute 20.

[0037] As Figure 2 shown, the structure of the spacing mechanism 6 is as follows: it includes a support 3 installed on the loading plate 2, a lifting cylinder 61 is installed on the side of the support 3, a transfer cylinder 62 is installed at the output end of the lifting cylinder 61, a spacing seat 63 is installed at the output end of the transfer cylinder 62, and pin shafts 631 are installed at the bottom of the spacing seat 63 at intervals along the length direction of the chute 20. The direction in which the transfer cylinder 62 drives the spacing seat 63 to move is the same as the length direction of the chute 20.

[0038] In actual use, the lifting cylinder 61 descends, the pin shafts 631 extend downward into the corresponding tubular products 10, and combined with the operation of the transfer cylinder 62, the tubular products 10 are pushed forward by the pin shafts 631 to a preset position, realizing the spacing between adjacent tubular products 10.

[0039] In this embodiment, as Figure 3 shown, two pin shafts 631 are installed at the bottom of the spacing seat 63 at intervals. The frontmost one of the closely arranged tubular products 10 is moved forward to the middle position by the rear pin shaft 631, and then the tubular product 10 at the middle position is moved forward to the clamping position of the clamping member 5 by the front pin shaft 631. Through the setting of the front and rear two pin shafts 631, they move forward synchronously and simultaneously, effectively ensuring the spaced feeding of the corresponding tubular products 10 and effectively ensuring the operation efficiency.

[0040] Pin shafts 631 are respectively installed at the four corners of the bottom surface of a single spacing seat 63, and a single spacing mechanism 6 corresponds to the spaced transfer of the tubular products 10 in two chutes 20, helping to improve and ensure the feeding and spacing efficiency of the tubular products 10.

[0041] AsFigure 3 As shown in the figure, the lateral blocking mechanism 8 includes two sets of blocking members 80 arranged at intervals in the front and rear directions, and the distance between the two sets of blocking members 80 is the same as the cross-sectional dimension of a single tubular product 10; the two sets of blocking members 80 are driven by the same power to switch between the states of laterally extending and laterally retracting.

[0042] In this embodiment, since the external feeding mechanism continuously feeds materials into the material trough 20, it is necessary to combine the lateral blocking mechanism 8 to block the tubular products 10 to ensure interval feeding.

[0043] During use, the rear blocking member 80 extends laterally to block the two tubular products 10 arranged closely in the front, while the front blocking member 80 retracts laterally to facilitate the smooth advancement of the tubular product 10 at the forefront by the interval mechanism 6; then, the states of the two blocking members 80 are switched, the front one extends laterally, and the rear one retracts laterally, which is convenient for the tubular products 10 closely arranged in the material trough 20 to advance forward to the preset position aligned with the interval mechanism 6 with continuous feeding.

[0044] As Figure 4 shown, the structure of the lateral blocking mechanism 8 is as follows: it includes a blocking cylinder 81 and a blocking seat 85 that are installed at intervals in the front and rear directions on the bottom surface of the feeding plate 2. A moving plate 82 is installed at the output end of the blocking cylinder 81, and the moving plate 82 is slidably fitted in the front and rear directions on the blocking seat 85; lateral grooves 851 are formed at intervals in the front and rear directions at the edge of the blocking seat 85, and blocking members 80 are slidably fitted in the lateral grooves 851; a sliding groove 821 is formed on the moving plate 82, and the inner end of the blocking member 80 is fitted in the sliding groove 821 through a sliding pin 83.

[0045] As Figure 4 and Figure 5 shown, the sliding groove 821 includes two symmetric sections in the front and rear directions, and an angle with an outward opening is formed between the two sections; as the blocking cylinder 81 works, the moving plate 82 moves in the front and rear directions, prompting the two blocking members 80 to switch between lateral expansion and contraction along the sliding groove 821.

[0046] In Figure 4 the shown embodiment, the front blocking member 80 is in a laterally extended state at the end of the sliding groove 821, and the rear blocking member 80 is in a laterally retracted state in the middle of the sliding groove 821; the blocking cylinder 81 pulls the moving plate 82 forward, and the state of the blocking member 80 switches to as Figure 5 shown. At this time, the front blocking member 80 is in a laterally retracted state in the middle of the sliding groove 821, and the rear blocking member 80 is in a laterally extended state at the rear end of the sliding groove 821; during the state switching process, the lateral groove 851 provides guidance and limitation for the extension and retraction actions of the blocking member 80.

[0047] The single blocking member 80 has a U-shaped structure with an opening facing the moving plate 82. A sliding pin 83 is installed between the two arms of the U-shaped structure, which facilitates the assembly of the blocking member 80 and the moving plate 82; the outer end of the blocking member 80 has a V-shaped convex structure, which facilitates the blocking of the tubular product 10 when the blocking member 80 extends laterally.

[0048] In this embodiment, an upper cover 84 is also installed above the blocking member 80 and the moving plate 82. The upper cover 84 is fixedly locked with the blocking seat 85, so as to accommodate the blocking member 80 and the sliding groove 821 inside.

[0049] A flange is formed on the outer wall surface of the pipe orifice of the tubular product 10 by circumferential extension. The tubular product 10 is hung on the material groove 20 via the flange; with the continuous feeding of the external feeding mechanism, the tubular product 10 can continuously move forward along the material groove 20.

[0050] It also includes columns 11 arranged at intervals on the left and right. The lower parts of the columns 11 are jointly installed with a bottom plate 1, and the middle parts of the columns 11 are jointly installed with a middle plate 12, which constitutes the structural support of the interval feeding mechanism; the feeding plate 2 is installed above the middle plate 12 at intervals via a vertical plate 21, and a space capable of accommodating the tubular product 10 is formed between the feeding plate 2 and the middle plate 12.

[0051] A clamping and rotating mechanism 4 is installed on the bottom plate 1, and a clamping member 5 is installed at the top of the clamping and rotating mechanism 4; a support plate one 13 and a support plate two 14 are jointly installed on the upper parts of the columns 11. The support plate one 13 is located below the support plate two 14. A vision component 7 is installed on the support plate two 14, and a light source is installed on the support plate one 13. The vision component 7 is located directly above the clamping member 5.

[0052] In this embodiment, after the clamping member 5 clamps the tubular product 10, it can be rotated via the clamping and rotating mechanism 4, which facilitates the end face feature detection of the tubular product 10 by the vision component 7, effectively ensuring the accuracy of the feeding posture of the tubular product 10 and avoiding the upside-down of the tubular product 10 during feeding.

[0053] As Figure 6 shown, the structure of the clamping and rotating mechanism 4 is: including a lifting cylinder 41 installed on the bottom plate 1, a lifting seat 43 is installed at the output end of the lifting cylinder 41, a motor 42 is installed on the bottom surface of the lifting seat 43, the output end of the motor 42 passes upward through the lifting seat 43 and then a clamping cylinder 44 is installed, and the upward output end of the clamping cylinder 44 is installed with a clamping member 5 that moves towards or away from each other.

[0054] During use, when the tubular product 10 moves to above the clamping member 5 by the interval mechanism 6, the lifting cylinder 41 works to push the clamping member 5 upward, the clamping cylinder 44 works to drive the clamping member 5 to move towards each other to clamp the tubular product 10, and then the motor 42 works to drive the tubular product 10 to rotate.

[0055] The utility model realizes the interval material distribution during the feeding of tubular products, has good stability and high reliability, is convenient for subsequent clamping by clamping parts and subsequent operations such as detection in sequence, is especially applicable to the metering drum of an injection pen, is convenient for subsequent automated operations, and has good practicability.

[0056] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is the difference from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0057] The above description is an interpretation of the utility model, not a limitation of the utility model. For the scope defined by the utility model, refer to the claims. Any form of modification can be made within the protection scope of the utility model.
