Description

Technical Field

[0001] This utility model relates to the field of medical supplies manufacturing technology, and in particular to an intermittent feeding device. Background Technology

[0002] In automated packaging production lines, especially before processes such as filling, labeling, and capping, precise spacing control is usually required for the closely packed, continuously conveyed solvent bottles, transforming them from a dense state to an intermittent feeding mode with orderly arrangement at set intervals. Currently, among devices that achieve interval feeding of bottles and cans, the spiral bottle-separating mechanism is one of the most widely adopted mainstream technologies. This mechanism involves a constant-speed rotating screw with a specific pitch and groove shape arranged along the direction of solvent bottle conveying. The spiral protrusions of the screw squeeze into the gaps between the solvent bottles through rotation, and its shape propels the solvent bottles in front to accelerate forward while hindering the solvent bottles behind, thereby creating and maintaining the required fixed spacing between two adjacent solvent bottles.

[0003] However, due to the limited shape of the solvent bottles, when the solvent bottles are arranged too closely or there is slight front-to-back compression, the gap between two adjacent solvent bottles is extremely small or even zero. This causes the screw's spiral protrusion to be unable to be inserted, and instead it directly collides or even hits the side wall of the bottle, resulting in damage to the bottle or jamming of the screw, creating a double hidden danger to production efficiency and production stability.

[0004] Therefore, providing an intermittent feeding device is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses an intermittent feeding device to solve the above-mentioned technical problems existing in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] This application provides an intermittent feeding device for conveying solvent bottles. The intermittent feeding device includes a conveyor line, a conveying screw, and a blocking structure; wherein:

[0008] The conveyor line is connected to the conveyor screw, and the two conveyor screws are arranged opposite each other to define the passage area of ​​the solvent bottle. The blocking structure is provided on the conveying path of the conveyor line. The blocking structure is configured to block the solvent bottle, so that a gap area is formed between two adjacent solvent bottles for the spiral protrusion of the conveyor screw to penetrate.

[0009] Furthermore, the blocking structure includes a driving member, a first baffle, and a second baffle. The driving member is disposed on a first side of the conveyor line, and the first baffle is connected to the driving member. The second baffle is fixedly disposed on a second side of the conveyor line. The driving member is configured to drive the first baffle to abut against the solvent bottle and to drive the solvent bottle to abut against the second baffle.

[0010] Furthermore, the first baffle is connected to a first rubber pad, which is used to contact the solvent bottle; and / or, the second baffle is connected to a second rubber pad, which is used to contact the solvent bottle.

[0011] Furthermore, the driving component is a cylinder, a linear motor, or an electric push rod.

[0012] Furthermore, the intermittent feeding device also includes a detection sensor, which is configured corresponding to the blocking structure. When the detection sensor detects the presence of the solvent bottle, the drive unit actuates to block the solvent bottle.

[0013] Furthermore, the detection sensor is positioned corresponding to the neck of the solvent bottle.

[0014] Furthermore, the intermittent feeding device also includes a support frame, which includes a first rod and a second rod connected to each other. The first rod extends longitudinally, and the second rod extends laterally. The detection sensor is located on the second rod, and the height of the second rod relative to the first rod is adjustable.

[0015] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0016] The intermittent feeding device of this application has a blocking structure that can physically limit the solvent bottles on the conveying path of the conveyor line, forcibly pausing the forward movement of subsequent solvent bottles. This forces two adjacent solvent bottles to be separated by a controllable distance. At this time, the spiral protrusion of the conveying screw does not need to "squeeze" into the natural gap between the two solvent bottles, but precisely probes into the existing artificial gap area with guaranteed size. This method eliminates the situation where the spiral protrusion squeezes and damages the solvent bottles or jams the conveying screw due to the extremely small or even zero gap between the solvent bottles, thereby ensuring the stability, reliability and safety of the solvent bottle spacing conveying.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0024] The following is in conjunction with the appendix Figures 1-2 The intermittent feeding device provided in this application will be described in detail through specific embodiments and application scenarios.

[0025] Please see Figure 1 and Figure 2This application discloses an intermittent feeding device for conveying a solvent bottle 600. Specifically, the disclosed intermittent feeding device includes a conveyor line 100, a conveyor screw 200, and a blocking structure 300. The conveyor line 100 is connected to the conveyor screw 200 and is located upstream of the conveyor screw 200. The conveyor line 100 is used to convey the solvent bottle 600 and transfer the solvent bottle 600 to the conveyor screw 200. For example, the conveyor line 100 can be a belt conveyor line. Two conveyor screws 200 are arranged opposite to each other and parallel downstream of the conveyor line 100, and the spiral protrusions 210 of the two conveyor screws 200 are correspondingly arranged. The passage area of ​​the solvent bottle 600 is defined between the two conveyor screws 200. When the conveyor line 100 transfers the solvent bottle 600 to the conveyor screw 200, the solvent bottle 600 is placed in the spiral recess of the two conveyor screws 200.

[0026] In this embodiment, the blocking structure 300 is disposed on the conveying path of the conveying line 100, and the blocking structure 300 is disposed adjacent to the conveying screw 200. In two adjacent solvent bottles 600, when the blocking structure 300 releases the previous solvent bottle 600 to the conveying screw 200, the blocking structure 300 is used to block the next solvent bottle 600, so that a gap area is formed between the two adjacent solvent bottles 600 for the spiral protrusion 210 of the conveying screw 200 to penetrate.

[0027] Based on the above technical solution, in specific applications, the intermittent feeding device of this application embodiment can physically limit the solvent bottle 600 on the conveying path of the conveying line 100, forcibly pausing the forward movement of subsequent solvent bottles 600, so that two adjacent solvent bottles 600 are forcibly separated by a controllable distance. At this time, the spiral protrusion 210 of the conveying screw 200 does not need to "forcefully squeeze" into the natural gap between the two solvent bottles 600, but precisely probes into the existing artificial gap area with guaranteed size. This method eliminates the situation where the spiral protrusion 210 squeezes and damages the solvent bottle 600 or the conveying screw 200 jams due to the extremely small or even zero gap between the solvent bottles, thereby ensuring the stability, reliability and safety of the solvent bottle 600 spacing conveying.

[0028] In this embodiment, the blocking structure 300 includes a driving member, a first baffle 320, and a second baffle 330. The driving member is disposed on a first side of the conveyor line 100, and the first baffle 320 is connected to the driving member. The second baffle 330 is fixedly disposed on a second side of the conveyor line 100. The solvent bottle 600 passes between the first baffle 320 and the second baffle 330. When the solvent bottle 600 is located between the first baffle 320 and the second baffle 330, the driving member can drive the first baffle 320 to move so that the first baffle 320 is in contact with the solvent bottle. When the first baffle 320 moves laterally to abut against the second baffle 330, the first baffle 320 and the second baffle 330 clamp the solvent bottle 600, thus physically blocking it. This clamping method prevents the solvent bottle 600 from rotating and tipping due to single-point force, ensuring good posture stability and maintaining good contact with subsequent solvent bottles 600. The running portion of the solvent bottles 600 accumulates stably on the conveyor line 100. Exemplarily, the driving component can be a linear motor, an electric push rod, or a cylinder. In a preferred embodiment, the driving component can be a cylinder. Since the generated gap area only needs to allow the conveying screw 200 to spiral in, high precision control is not required. A cylinder as a driving component has the advantages of low cost and fast response.

[0029] In a further technical solution, a first rubber pad 340 is connected to the first baffle 320. The first rubber pad 340 is located on the side of the first baffle 320 facing the solvent bottle 600. The first rubber pad 340 is used to contact the solvent bottle 600. For example, the first rubber pad 340 is a rubber pad, a silicone pad, or an elastic pad made of other polymer materials. When the first baffle 320 contacts the solvent bottle 600, the first rubber pad 340 can undergo elastic deformation to play a buffering role, which can prevent the first baffle 320 from rigidly contacting the solvent bottle 600 and causing the solvent bottle 600 to crack or even break. At the same time, the first rubber pad 340 has a large friction force when in contact with the solvent bottle 600, which can stably support the solvent bottle 600 during the pushing and clamping process, so that the solvent bottle 600 will not deviate or tilt.

[0030] In this embodiment, the first rubber pad 340 has an abutting surface facing the solvent bottle 600. The first rubber pad 340 contacts the solvent bottle 600 through this abutting surface. It is understood that this abutting surface should be adapted to the outer contour surface of the solvent bottle 600 to ensure that the two have a large contact area to ensure the stability of pushing and clamping. It should be noted that the first rubber pad 340 and the first baffle 320 are detachably connected. For example, the two can be connected and fixed by means of threaded connection, snap-fit, etc. When the product line changes to solvent bottles 600 with different appearances, the corresponding first rubber pad 340 can be adaptively replaced to adapt the first rubber pad 340 to the solvent bottle 600.

[0031] In a further technical solution, the second baffle 330 is connected with a second rubber pad, which is used to contact the solvent bottle 600. In a preferred embodiment, the second rubber pad is detachably connected to the second baffle 340, which will not be described in detail here.

[0032] In this embodiment of the application, the intermittent feeding device also includes a detection sensor 400, which is provided corresponding to the blocking structure 300. For example, the detection sensor 400 can be a photoelectric sensor. When the detection sensor 400 detects the presence of the solvent bottle 600, the control device can control the drive to block the solvent bottle 600.

[0033] In two adjacent solvent bottles 600, the neck size is often smaller than the body size. In order to facilitate the detection sensor 400 to accurately determine whether the solvent bottle 600 has moved between the first baffle 320 and the second baffle 330, in this embodiment, the detection sensor 400 is set to correspond to the neck of the solvent bottle 600. In this way, the detection sensor 400 can clearly detect whether it is blocked by the solvent bottle. When the detection sensor 400 is blocked by the solvent bottle 600, it means that the solvent bottle 600 has just moved to the position corresponding to the first baffle 320 and the second baffle 330.

[0034] In this embodiment, the intermittent feeding device further includes a support 500, which includes a first rod 510 and a second rod 520 connected to each other. The first rod 510 extends longitudinally, and the second rod 520 extends laterally. A detection sensor 400 is disposed on the second rod 520, and the height of the second rod 520 relative to the first rod 510 is adjustable. For example, the second rod 520 can be connected to the first rod 510 by a locking clamp. By adjusting the height of the second rod 520, the detection sensor 400 can be aligned with the identification part of the solvent bottle 600, such as the neck of the solvent bottle 600.
