Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, specifically to a flip-over transfer device. Background Technology

[0002] In the daily operations of pharmacies or drug warehouses, the packaging of boxed medicines typically relies on automated equipment to improve efficiency. A dispensing device grabs medicines from the storage area and places them on a transfer box or conveyor, which then guides the medicine boxes into the packaging bag of the packing device for final packaging.

[0003] However, in practical application, this process has a significant problem: because the boxed medications are dropped into the packaging bag sequentially, they are prone to stacking inside the bag. This means that the medications are not evenly distributed when they fall into the bag, with some stacked vertically. This stacking prevents the medications from fully utilizing the bottom space of the bag, and may even cause the stack height to exceed the opening of the bag. Some medications may not be able to fit into the bag, leading to packaging failure. Alternatively, medications exceeding the bag opening may fall during operation, resulting in loss or damage, affecting the accuracy and safety of medication management.

[0004] This problem not only reduces packaging efficiency but may also increase the complexity and error rate of drug management. Therefore, optimizing the design of the packaging device for boxed drugs and avoiding stacking of boxed drugs has become an unavoidable issue in improving the performance of automated packaging systems in pharmacies and drug warehouses. Summary of the Invention

[0005] The purpose of this invention is to provide a reversible transfer device to solve the above-mentioned problems.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A flip-up transfer device is used to transfer medicines and is positioned above the medicine hopper of a packaging device. The transfer device includes a transfer box, a flipping component, and a blocking component. The transfer box has openings at both ends, with the two openings being a medicine inlet and a medicine outlet, respectively. Medicines are stacked vertically inside the transfer box. The flipping component can rotate the transfer box to either the medicine inlet or the medicine outlet position. The blocking component can either block the medicine outlet or allow it to open. When the transfer box is in the medicine inlet position, the medicine inlet is higher than the medicine outlet or the medicine inlet and the medicine outlet are at the same height, and the blocking component blocks the medicine outlet. When the transfer box is in the medicine outlet position, the medicine inlet is higher than the medicine outlet, and the medicine outlet faces the entrance of the medicine hopper, and the blocking component allows the medicine outlet to open.

[0008] As a further improvement of the present invention, the flipping assembly includes a first mounting base, a first motor and a rotating shaft. The first motor is mounted on the first mounting base, and a pair of bearings with seats are provided on the first mounting base. The rotating shaft is mounted on the bearings with seats. The first motor can drive the rotating shaft to rotate around the axis of the rotating shaft, and the rotating shaft can drive the transfer box to rotate synchronously.

[0009] As a further improvement of this utility model, a first positioning member is provided on the rotating shaft. The first positioning member rotates synchronously with the rotating shaft. A rotation sensor group is provided on the first mounting base. The rotation sensor group is used to detect the position of the first positioning member.

[0010] As a further improvement of the present invention, the rotation sensor group includes a first photoelectric sensor and a second photoelectric sensor. The first photoelectric sensor and the second photoelectric sensor are disposed on the rotation path of the first positioning member. The arc of the rotation path is within °. When the first positioning member is captured by the first photoelectric sensor, the transfer box is located at the medicine inlet position. When the first positioning member is captured by the second photoelectric sensor, the transfer box is located at the medicine outlet position.

[0011] As a further improvement of the present invention, the blocking component includes a second mounting base, on which a second motor, a synchronous pulley group and a baffle are provided. A pressure plate is provided on the synchronous belt of the synchronous pulley group, and the baffle is connected to the pressure plate. The second motor can drive the synchronous pulley group to move, thereby causing the baffle to move closer to or away from the drug outlet.

[0012] As a further improvement of this utility model, a second positioning element is provided on the baffle, and a linear sensor group is provided on the second mounting base. The linear sensor group is used to detect the position of the second positioning element.

[0013] As a further improvement of the present invention, the linear sensor group includes a third photoelectric sensor and a fourth photoelectric sensor. The third photoelectric sensor and the fourth photoelectric sensor are arranged on the moving path of the second positioning member. When the second positioning member is captured by the third photoelectric sensor, the baffle fully opens the drug outlet. When the second positioning member is captured by the fourth photoelectric sensor, the baffle completely blocks the drug outlet.

[0014] As a further improvement of this utility model, a guide mechanism is provided on the second mounting base, which is used to guide the movement of the baffle.

[0015] As a further improvement of this utility model, several slots are provided on the two side plates of the transfer box, and partitions can be inserted into the slots.

[0016] As a further improvement of this utility model, a flip base is provided at the bottom of the transfer box, and the side of the rotating shaft that is in contact with the flip base is a plane.

[0017] The beneficial effects of this utility model are as follows:

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0025] If the description of this utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), then the directions involved need to be defined. For example, "To clearly express the position and direction described in this utility model, the operator of the instrument is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0026] A flip-up transfer device is installed above the medicine hopper 4 of the packaging device for temporarily storing and transferring boxed medicines, such as... Figure 1 , Figure 2 As shown, the transfer device includes a transfer box 1, a flipping component, and a blocking component. The transfer box 1 has openings at both ends, with the two openings being a drug inlet 101 and a drug outlet 102, respectively. The transfer box 1 has a drug storage space. After the preceding drug retrieval device retrieves the drug, it is placed into the transfer box 1 (i.e., the drug storage space) through the drug inlet 101. The drugs are placed in the transfer box 1 in a stacked manner. The drugs in the transfer box 1 can leave the transfer box 1 through the drug outlet 102. The flipping component can drive the transfer box 1 to rotate, and the extreme positions of rotation are the inlet position and the outlet position. The blocking component can block the outlet 102 or open the outlet 102. When the transfer box 1 is in the inlet position, the inlet 101 is higher than the outlet 102 or the inlet 101 and the outlet 102 are at the same height. The blocking component blocks the outlet 102. This design can ensure that when the medicine enters the transfer box 1, it can pass smoothly through the inlet 101 and enter the interior of the transfer box 1 without getting stuck or falling due to the height difference. When the transfer box 1 is in the outlet position, the inlet 101 is higher than the outlet 102, and the outlet 102 faces the entrance of the medicine hopper 4. The blocking component opens the outlet 102.

[0027] In one embodiment of this utility model, the flipping assembly includes a first mounting base 201, a first motor 202, and a rotating shaft 203. The first motor 202 is mounted on the first mounting base 201, and a pair of bearings 204 with seats are provided on the first mounting base 201. The rotating shaft 203 is mounted on the bearings 204 and can rotate within the bearings 204. The first motor 202 can drive the rotating shaft 203 to rotate around its axis, and the rotating shaft 203 can drive the transfer box 1 to rotate synchronously. Furthermore, the first mounting base 201 can be mounted on the medicine hopper 4 to ensure the relative position between the transfer box 1 and the medicine hopper 4, facilitating the falling of medicine from the transfer box 1 into the medicine hopper 4.

[0028] In one embodiment of this utility model, a first positioning member 205 is provided at the end of the rotating shaft 203 away from the first motor 202. The first positioning member 205 rotates synchronously with the rotating shaft 203. A rotation sensor group is provided on the first mounting base 201, and the rotation sensor group is used to detect the position of the first positioning member 205. By detecting the position of the first positioning member 205, the rotation sensor group can provide real-time feedback of the position information of the transfer box 1 to the control system, ensuring that the transfer box 1 can accurately reach the preset position during rotation.

[0029] Specifically, the rotation sensor group includes a first photoelectric sensor 206 and a second photoelectric sensor 207. The first and second photoelectric sensors 206 and 207 are positioned on the rotation path of the first positioning member 205, and the arc of the rotation path does not exceed 180°. When the first positioning member 205 blocks the optical path of the first photoelectric sensor 206, the intermediate transfer box 1 is positioned at the drug inlet position; when the first positioning member 205 blocks the optical path of the second photoelectric sensor 207, the intermediate transfer box 1 is positioned at the drug outlet position. This precise positioning and detection method ensures that the intermediate transfer box 1 maintains the correct position and posture during drug inlet and outlet processes, improving the accuracy and stability of drug transfer. This highly automated design significantly reduces manual intervention, lowers labor costs and error rates, and improves the efficiency and accuracy of drug packaging. Furthermore, the first photoelectric sensor 206 and the second photoelectric sensor 207 are fixed in the first mounting hole 208 on the first mounting base 201 by fasteners. The first mounting hole 208 is a slotted hole to facilitate adjustment of the mounting position of the first photoelectric sensor 206 and the second photoelectric sensor 207, thereby adapting to different needs.

[0030] As one embodiment of this utility model, such as Figures 1-3 As shown, the blocking assembly includes a second mounting base 301, on which a second motor 302, a synchronous pulley set 303, and a baffle 304 are disposed. A pressure plate 305 is disposed on the synchronous belt of the synchronous pulley set 303, and the baffle 304 is connected to the pressure plate 305. The second motor 302 can drive the synchronous pulley set 303 to move. The pressure plate 305 located on the synchronous belt of the synchronous pulley moves linearly with the synchronous belt. The baffle 304 moves linearly toward or away from the medicine outlet 102 with the pressure plate 305, thereby achieving the blocking or opening of the medicine outlet 102.

[0031] In one embodiment of the present invention, a second positioning member 306 is provided on the baffle 304. The second positioning member 306 moves linearly with the baffle 304. A linear sensor group is provided on the second mounting base 301. The linear sensor group is used to detect the position of the second positioning member 306.

[0032] Specifically, the linear sensor group includes a third photoelectric sensor 307 and a fourth photoelectric sensor 308. These two sensors are positioned on the moving path of the second positioning member 306. When the second positioning member 306 blocks the light path of the third photoelectric sensor 307, it indicates that the baffle 304 is fully open at the drug outlet 102. When the second positioning member 306 blocks the light path of the fourth photoelectric sensor 308, it indicates that the baffle 304 is completely blocked at the drug outlet 102. This precise positioning detection method ensures that the baffle 304 remains in the correct position during drug intake and dispensing, cooperating with the flipping assembly to improve the accuracy and stability of drug transfer. Furthermore, the third photoelectric sensor 307 and the fourth photoelectric sensor 308 are fixed to the second mounting hole 309 on the second mounting base 301 by fasteners. The second mounting hole 309 is a slotted hole to facilitate adjustment of the mounting position of the third photoelectric sensor 307 and the fourth photoelectric sensor 308, thereby adapting to different needs.

[0033] In one embodiment of this utility model, a guide mechanism is provided on the second mounting base 301 to guide the movement of the baffle 304. Specifically, the guide mechanism includes a slider 310 and a slide rail 311. The extension direction of the slide rail 311 is parallel to the movement path of the baffle 304. The slider 310 can slide linearly on the slide rail 311. A timing belt fixing seat 312 is provided on the slider 310. The timing belt fixing seat 312 is connected to the outer side of the timing belt, and the pressure plate 305 is connected to the inner side of the timing belt. The timing belt fixing seat 312 and the pressure plate 305 are arranged opposite to each other, thereby ensuring that the timing belt on one side will not deform due to the gravity of the baffle 304 during movement, ensuring that the baffle 304 always maintains a straight line during movement, avoiding deviation or jamming, and thus ensuring the control accuracy and stability of the dispensing port 102.

[0034] In one embodiment of this utility model, several slots 103 are provided on both side plates of the transfer box 1. Partitions can be inserted into the slots 103 for loading and separating medicine boxes. For transfer boxes 1 without partitions, the preceding medicine dispensing device actively stacks the medicines vertically within the transfer box 1, then tilts and pours them into the medicine hopper 4. For transfer boxes 1 with pre-installed partitions, the preceding medicine dispensing device can place the medicines into each layer of partitions, or stack the medicines vertically. The number of partitions can be determined based on the height of the medicines. The slots 103 and partitions rationally divide the internal space of the transfer box 1, allowing medicines to be placed orderly within each separated area during loading, avoiding collisions between medicines.

[0035] As an embodiment of the present utility model, a flip base 104 is provided at the bottom of the transfer box 1. The side of the rotating shaft 203 that is in contact with the flip base 104 is a plane. Thus, during the rotation of the rotating shaft 203, the rotating shaft 203 can push the flip base 104 to rotate.

[0036] The working principle of this utility model is as follows:

[0037] When the medicine is being dispensed, the control system issues a medicine feeding command. The second motor 302 drives the baffle 304 to approach the medicine outlet 102. When the second positioning component 306 is captured by the third photoelectric sensor 307, the linear sensor group sends a signal to the control system. After receiving the signal, the control system immediately controls the second motor 302 to stop rotating. At this time, the baffle 304 completely blocks the medicine outlet 102 to prevent the medicine from accidentally falling out of the medicine outlet 102 during the medicine feeding process. According to the command of the control system, the flipping component is driven by the first motor 202 to rotate the rotating shaft 203. The rotating shaft 203 drives the transfer box 1 to rotate synchronously. When the first positioning component 205 is captured by the first photoelectric sensor 206, the rotation sensor group sends a signal to the control system. After receiving the signal, the control system immediately controls the first motor 202 to stop rotating. At this time, the transfer box 1 is in the medicine feeding position. The preceding medicine dispensing device dispenses the medicine and stacks the medicine in the transfer box 1.

[0038] After the medication is dispensed, the control system issues a dispensing command. Following this command, the flipping assembly, driven by the first motor 202, reverses the rotation of the shaft 203. The shaft 203 then drives the transfer box 1 to rotate synchronously. When the first positioning element 205 is captured by the second photoelectric sensor 207, the rotation sensor group sends a signal to the control system. Upon receiving the signal, the control system immediately stops the first motor 202. At this point, the transfer box 1 is in the dispensing position. The second motor 302 moves the baffle 304 away from the dispensing port 102. When the second positioning element 306 is captured by the fourth photoelectric sensor 308, the linear sensor group sends a signal to the control system. Upon receiving the signal, the control system immediately stops the second motor 302. At this point, the baffle 304 has fully opened the dispensing port 102, and the medication in the transfer box 1 falls into the dispensing hopper 4 under gravity, evenly distributing at the bottom of the packaging bag (e.g., ...). Figure 4 As shown in the figure, the bottom space of the packaging bag is fully utilized. Since the medicines were originally stacked vertically in the transfer box 1, multiple medicines fall at the same height during the falling process. Therefore, they will not be stacked vertically in the packaging bag, but will be evenly distributed in the packaging bag, which is beneficial for subsequent packaging of medicines, increases the loading capacity of the packaging bag, and effectively improves the efficiency and quality of medicine packaging.

[0039] The flip-over transfer device provided by this utility model optimizes the process of medicines (especially boxed medicines) entering the medicine dropper 4 through the synergistic action of the flipping component and the blocking component. It makes full use of the bottom space of the packaging bag, avoids the problem of medicines stacking up and down in the packaging bag, realizes the orderly transfer and accurate delivery of medicines, improves packaging efficiency and the safety of medicine management, and reduces the risk of medicine loss or damage. Moreover, the above-mentioned transfer device has a simple structure, high reliability, and is easy to maintain and repair, and is suitable for automated packaging systems in various pharmacies or drug warehouses.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
