Description

Technical Field

[0001] This utility model relates to a tipping device, specifically a tipping device for bundled medicine boxes. Background Technology

[0002] In the pharmaceutical manufacturing and packaging industry, the automated conveying and handling of bundled medicine boxes is a key step in improving production efficiency. However, the current method of conveying bundled medicine boxes has a significant problem: the QR codes on the medicine boxes cannot be effectively exposed during the conveying process, making it impossible for subsequent coding equipment to accurately identify and input the QR codes on the upright bundled medicine boxes. Therefore, it is necessary to flip the bundled medicine boxes upside down during the conveying process so that the QR codes face upwards, facilitating the operation of the coding equipment.

[0003] While existing medicine box tipping devices can achieve certain functions, they have many shortcomings. For example, patent "CN217076057U, A Bar-Type Tipping Device" applies force to the medicine box using only a single bar, a design with obvious flaws. When the force is not applied to the center of gravity of the medicine box, it easily slides off the sides of the bar as the conveyor belt moves forward, causing tipping failure. Furthermore, existing devices have poor adaptability to medicine boxes of different heights and widths, making it difficult to meet diverse production needs. Utility Model Content

[0004] The purpose of this invention is to provide a device for tipping over bundled medicine boxes, which solves the problem of low success rate of existing medicine box tipping devices.

[0005] To solve the above problems, the technical solution of this utility model is as follows:

[0006] A device for tipping over bundled medicine boxes includes a shaft with both ends connected to support seats mounted on a conveyor frame. The shaft is connected to multiple blocking rods via multiple cross connectors, and the blocking rods are rotatable around the shaft.

[0007] Furthermore, a height-adjustable limiting rod is installed on the support base, and a blocking rod abuts against the limiting rod, with the bundled medicine box passing under the limiting rod.

[0008] Furthermore, a buffer pad is wrapped around the limit rod.

[0009] Furthermore, it also includes a spring-loaded component installed on the tipping device, which is used to drive the blocking rod to abut against the limiting rod.

[0010] Furthermore, it also includes a blocking element, which is connected to the lower end of the blocking rod.

[0011] Furthermore, the blocking element is L-shaped.

[0012] Furthermore, the support base is detachably connected to the conveyor frame via fasteners, and an adjustment pad is provided between the support base and the conveyor.

[0013] Furthermore, scale lines are provided on the stop bar.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This device uses multiple blocking rods to obstruct the bundled medicine box. The blocking rods contact the sides of the medicine box and apply resistance, causing the center of gravity of the medicine box to change and allowing it to tip over. Because the blocking rods apply force at multiple points on the side of the medicine box, the problem of the medicine box sliding off the sides of the blocking rods is effectively prevented, significantly improving the success rate of tipping.

[0016] 2. The blocking rod can rotate around the shaft and automatically adjust its position according to the height change after the medicine box is tipped over. After tipping, the blocking rod falls and abuts against the limit rod, the height of which is adjustable to accommodate medicine boxes of different heights. Furthermore, the support base is connected to the conveyor via a height-adjusting pad, allowing for further adjustment of the overall height of the device according to the height of the medicine box, ensuring the device can accommodate various sizes of medicine boxes.

[0017] 3. Wrapping a buffer pad around the limit rod reduces noise when the blocking rod collides with the limit rod, while also protecting the mechanical structure of the device. Furthermore, the device is equipped with a spring-loaded component (such as a tension spring). During the tipping of the medicine box, the blocking rod and the spring-loaded component are lifted, causing deformation and creating resistance against the medicine box. This design is particularly effective for taller and heavier medicine boxes, providing greater resistance and ensuring a smooth tipping.

[0018] 4. An L-shaped stopper is connected to the lower end of the stopper bar. Its contact point is located above the center of gravity of the medicine box, which can effectively disrupt the stability of the medicine box, causing its center of gravity to shift and causing it to tip over. The design of the L-shaped stopper not only increases the contact area with the medicine box, but also ensures that the resistance is horizontally distributed on the side of the medicine box, avoiding tipping failure due to uneven force.

[0024] 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.

[0025] Example 1:

[0026] like Figure 1 and 2 As shown, a medicine box tipping device includes a shaft 4. Both ends of the shaft 4 are connected to a support seat 3 mounted on the frame of a conveyor 1 via bearings. The support seat 3 and the shaft 4 form a gate-shaped structure through which the medicine box passes. The shaft 4 is connected to multiple blocking rods 2 via multiple cross connectors 5. The height of the blocking rods 2 can be adjusted by tightening or loosening the screws on the cross connectors 5. At the same time, the blocking rods 2 can rotate around the shaft 4.

[0027] like Figure 3 As shown, during the conveyor 1, the upper part of the bundled medicine box pushes the blocking rod 2 to flip, so that the weight of the blocking rod 2 itself forms a resistance to the bundled medicine box. Under the action of resistance, the center of gravity of the bundled medicine box changes and tilts backward to achieve the overturning. After the bundled medicine box is overturned, the blocking rod 2 then falls back to its original position under its own weight to overturn the next bundled medicine box.

[0028] In addition, the front-to-back position and height of the blocking rod 2 can be adjusted by the cross connector 5, so that it can overturn bundled medicine boxes of different sizes and heights.

[0029] Example 2:

[0030] Furthermore, a height-adjustable limiting rod 6 is installed on the support base 3, and the blocking rod 2 abuts against the limiting rod 6, with the bundled medicine box passing under the limiting rod 6. Multiple threaded holes are sequentially formed from top to bottom on one side of the support base 3, and both ends of the limiting rod 6 are threadedly connected to the support base 3 via screws. By connecting the limiting rod 6 to the threaded holes at different positions, the height of the limiting rod 6 can be adjusted.

[0031] The function of the limiting rod 6 is as follows: after the bundled medicine box is tipped over, the blocking rod 2 is positioned above the medicine box, and then falls back onto the limiting rod 6 under its own weight. The limiting rod 6 ensures that the blocking rod 2 will not swing to the other side of the support base 3 due to inertia, thereby avoiding any impact on the subsequent tipping process of the bundled medicine box.

[0032] Furthermore, a rubber buffer pad 12 is wrapped around the limiting rod 6. The buffer pad 12 can reduce the noise of the blocking rod 2 hitting the limiting rod 6.

[0033] Example 3:

[0034] Furthermore, it also includes an L-shaped blocking member 9, which is connected to the lower end of the blocking rod 2. The blocking member 9 is used to impact the upper part of the bundled medicine box. When the bundled medicine box passes the L-shaped blocking member 9 with the conveyor belt, the contact part between the L-shaped blocking member 9 and the bundled medicine box is above the center of gravity of the bundled medicine box.

[0035] The L-shaped blocking member 9 has a large contact area with the bundled medicine box, and the contact part is located above the center of gravity of the bundled medicine box itself, which makes it easier to disrupt the original stability of the bundled medicine box, causing the center of gravity of the bundled medicine box to shift and causing the bundled medicine box to tip over. In this utility model, the shape of the blocking member is not limited to L-shape, but can also be a rod such as a round tube or a square tube. L-shape is the preferred shape of this utility model.

[0036] Example 4:

[0037] Furthermore, it also includes an elastic component installed on the tipping device, which drives the blocking rod 2 to abut against the limiting rod 6. The elastic component is a tension spring, with its two ends connected to the blocking component 9 and the support base 3, respectively.

[0038] During use, as the bundled medicine box tipps over, the blocking rod 2 and L-shaped blocking component 9 are lifted by the medicine box, causing the elastic component to deform. The weight of the blocking rod 2 and L-shaped blocking component 9, along with the tension of the elastic component recovering its deformation, together create resistance against the bundled medicine box. For bundled medicine boxes that are tall, heavy, and difficult to tip over, the farther they travel on the conveyor belt, the greater the resistance from the elastic component, thus increasing the success rate of tipping the medicine box.

[0039] For lightweight, easily tipped-over medicine boxes, the tension spring can be separated from the L-shaped stopper 9 to prevent excessive resistance from causing the medicine box to get stuck and unable to continue being transported backward with the conveyor belt.

[0040] Example 5:

[0041] Furthermore, the support base 3 is detachably connected to the conveyor 1 frame via fasteners. An adjusting pad 7 is provided between the support base 3 and the conveyor 1. By replacing the adjusting pad 7 with pads of different thicknesses, the height of the support base 3 can be adjusted. This allows the height of the support base 3 to be adjusted according to the height of the bundled medicine boxes, thus accommodating more bundled medicine boxes of different sizes.

[0042] Example 6:

[0043] Furthermore, a scale line 8 is provided on the blocking rod 2. The scale line 8 corresponds to different heights of the bundled medicine box, and the scale line 8 can be quickly adjusted to the corresponding height of the bundled medicine box.

[0044] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
