Description

Technical Field

[0001] This utility model relates to the field of medicine vending equipment, and in particular to an automatic output device for environmentally friendly bags for automatic medicine vending machines. Background Technology

[0002] With the continuous development of the automated medicine vending machine industry, various automated medicine dispensing equipment has been widely used in hospitals, pharmacies, and public places. However, in actual use, these devices still have some problems: for example, after dispensing medicine, users usually need to take the medicine away themselves, as there is a lack of automatic dispensing devices for environmentally friendly packaging bags. This means that users need to prepare extra bags after taking the medicine, affecting the convenience and environmental friendliness of the overall medicine purchasing experience.

[0003] A search revealed a patent (CN114743311B) for a dispensing mechanism, channel, and dispensing method for a medicine vending machine, with an authorization announcement date of December 13, 2024. This solution effectively solves problems such as jamming and spillage of lightweight medicines by incorporating gates, blocking components, and electromagnetic drive parts, improving the stability and reliability of the dispensing process. However, this design only focuses on the dispensing control of the medicine itself, neglecting the automatic output and use of eco-friendly bags, and lacking consideration for the convenience of users carrying the medicine after dispensing. It fails to form a complete integrated "dispensing + packaging" solution, limiting its applicability in modern green retail environments.

[0004] Currently, most eco-friendly bags on the market are flat-bottomed paper bags. Although some equipment has a simple bag-dispensing function, its structure is complex, its bag-dispensing efficiency is low, and it cannot supply bags on demand, which can easily lead to bag jamming or leakage, affecting the stability of equipment operation.

[0005] Therefore, it is necessary to further improve the automatic dispensing device for eco-friendly bags used in automatic medicine vending machines. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic output device for environmentally friendly bags in an automatic medicine vending machine, comprising an irregularly shaped upright plate and an output component. Two irregularly shaped upright plates are symmetrically arranged and connected by a connecting strip. An installation strip is provided on the irregularly shaped upright plate. A pressing component is provided between the irregularly shaped upright plates. An adjustment component is provided on the front surface of the irregularly shaped upright plate. An auxiliary component is arranged in an array on the lower surface of the irregularly shaped upright plate. A bag-moving component is installed inside a groove opened on the upper inner surface of the irregularly shaped upright plate. A telescopic component is provided on the connecting strip located on the lower side of the rear surface. The telescopic component is connected to the bag-moving component. The output component is located on the lower side of the front surface of the irregularly shaped upright plate.

[0008] Preferably, the adjustment assembly includes a stop bar, an adjustment groove, and a locking bolt. The locking bolt is disposed inside the adjustment groove, which is located on the front surface of the stop bar. The stop bar is connected to the lower side of the front surface of the irregularly shaped upright plate via the locking bolt.

[0009] Preferably, the clamping assembly includes a fixing cover, a clamping spring, and a clamping plate. The fixing cover is installed on the upper surface of the irregularly shaped upright plate by a snap lock. The two ends of the clamping spring are respectively connected to the clamping plate and the fixing cover. The clamping plate is disposed between the two irregularly shaped upright plates.

[0010] Preferably, the bag transfer assembly includes a slider, a movable strip, an insert plate, and a rubber strip. The slider is disposed on the lower surface of the movable strip and is installed in a groove. The insert plate is disposed on the movable strip, and the rubber strip is disposed at the end of the insert plate away from the movable strip.

[0011] Preferably, the telescopic assembly includes a connecting rib and an electric push rod. The connecting rib is disposed at the telescopic end of the electric push rod and on the lower surface of the movable strip. The electric push rod is disposed on the connecting strip located on the lower side of the rear surface.

[0012] Preferably, the auxiliary components are arranged in a front-to-back array. The auxiliary components include auxiliary rollers and mounting slots. The mounting slots are formed on the lower surface of the irregularly shaped upright plate, and the auxiliary rollers are rotatably mounted inside the mounting slots.

[0013] Preferably, the output component includes a driven roller, a mounting plate, an active roller, and a drive motor. The mounting plates are respectively set on the irregularly shaped upright plates on the left and right sides. The fixed plates at both ends of the driven roller are connected to the mounting plates through the clamping component two. The active roller is rotatably mounted between the mounting plates. The drive motor is set on the mounting plate, and the output shaft of the drive motor is connected to the active roller.

[0014] Preferably, the second clamping assembly includes a movable column, a tension spring, a horizontal plate, and a movable block. The movable column passes through a sliding hole in the horizontal plate and connects to the movable block. The tension spring is disposed between the horizontal plate and the movable block. The movable column is disposed in the middle of the tension spring. The horizontal plate is disposed on the mounting plate. The movable block is disposed on the fixed plate and is disposed in the movable groove opened on the mounting plate.

[0015] The working principle and usage principle of this utility model are as follows: the device is installed in the automatic medicine vending machine by the installation strip, so that the output component is aligned with the bag dispensing slot of the automatic medicine vending machine. The flat bottom environmental protection bag without handle can be put into the main frame formed by the irregular upright plate, ensuring that the bottom folded part of the environmental protection bag is located on the lower side. The compression spring can apply downward pressure to the compression plate, so that the compression plate presses the environmental protection bag stack tightly.

[0016] An external controller controls the operation of the electric push rod. When the electric push rod extends, it can drive the movable bar through the connecting rib plate. The movable bar can move in the slide groove through the slider. The insert plate can be inserted into the bottom fold position of the flat bottom eco-friendly bag. The movable bar drives the insert plate to move, thereby moving the bottom layer of the eco-friendly bags in the stack out of the irregular upright plate, so that the flat bottom eco-friendly bags move between the active roller and the driven roller of the output component.

[0017] An external controller controls the operation of the drive motor, which in turn drives the rotation of the active roller. The flat-bottomed eco-friendly bag is output between the active roller and the driven roller. The opposing pressure between the active roller and the driven roller ensures smooth output of the flat-bottomed eco-friendly bag.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The structure is highly integrated and simple, easy to maintain. The bag transfer component and the telescopic component work together to accurately output flat-bottomed eco-friendly bags and achieve on-demand bag supply.

[0020] 2. The flat-bottomed eco-friendly bag moves on the auxiliary rollers, which can drive the auxiliary rollers to rotate in the installation groove. This can reduce the friction of the flat-bottomed eco-friendly bag when it is discharged, ensure the stability of the bag discharge, reduce the occurrence of bag jamming or leakage, and ensure the stability of equipment operation.

[0021] 3. Flat-bottomed eco-friendly bags of different weights have different thicknesses. After the flat-bottomed eco-friendly bag enters between the active roller and the driven roller, the bag can lift the driven roller, thereby causing the movable block to move upward, putting pressure on the tension spring. At the same time, the tension spring can apply downward pressure to the driven roller, pressing the bag tightly to ensure smooth output and adapting to flat-bottomed eco-friendly bags of different weights.

The output component 8 is located on the lower side of the front surface of the irregularly shaped upright plate 1.

[0032] Specifically, the main frame is formed by symmetrically arranged irregularly shaped uprights 1 and connecting strips 5. Flat-bottomed eco-friendly bags without handles can be placed inside the main frame formed by the irregularly shaped uprights 1, ensuring that the folded bottom of the eco-friendly bag is located on the lower side. The mounting strips 3 are used to install the device inside the automatic medicine vending machine.

[0033] The pressing component 4 ensures the stability of the eco-friendly bag stack, the adjusting component 2 adapts to eco-friendly bags with different paper thicknesses, the auxiliary component 7 assists in the movement of the lower eco-friendly bags, the bag moving component 12 and the telescopic component 6 work together to achieve precise bag pushing, and the output component 8 completes the final bag output. The modular design has high integration and is easy to disassemble and maintain quickly. The irregular upright plate structure is lightweight and has reliable strength.

[0034] Furthermore, the adjustment assembly 2 includes a stop bar 201, an adjustment groove 202, and a locking bolt 203. The locking bolt 203 is disposed inside the adjustment groove 202, which is formed on the front surface of the stop bar 201. The stop bar 201 is connected to the lower side of the front surface of the irregular upright plate 1 through the locking bolt 203.

[0035] Specifically, the height of the baffle 201 can be adjusted according to the weight of the eco-friendly bags. The locking bolt 203 can fix the adjusted baffle 201, which can flexibly adapt to flat bottom bags of multiple weights. After adjustment, the stability is strong, and the baffle 201 can prevent multiple eco-friendly bags from being output at one time.

[0036] Furthermore, the clamping assembly 4 includes a fixed cover 401, a clamping spring 402, and a clamping plate 403. The fixed cover 401 is installed on the upper surface of the irregularly shaped upright plate 1 by a snap lock. The two ends of the clamping spring 402 are respectively connected to the clamping plate 403 and the fixed cover 401. The clamping plate 403 is disposed between the two irregularly shaped upright plates 1.

[0037] Specifically, the eco-friendly bag can be placed between the irregularly shaped uprights 1, and the compression spring 402 can apply downward pressure to the compression plate 403, so that the compression plate 403 presses the eco-friendly bag tightly, thereby improving the bag output efficiency and bag output stability.

[0038] Furthermore, the bag transfer assembly 12 includes a slider 1201, a movable strip 1202, an insert plate 1203, and a rubber strip 1204. The slider 1201 is disposed on the lower surface of the movable strip 1202 and is installed in the slide groove 10. The insert plate 1203 is disposed on the movable strip 1202, and the rubber strip 1204 is disposed at the end of the insert plate 1203 away from the movable strip 1202.

[0039] Furthermore, the telescopic assembly 6 includes a connecting rib 601 and an electric push rod 602. The connecting rib 601 is disposed at the telescopic end of the electric push rod 602 and on the lower surface of the movable strip 1202. The electric push rod 602 is disposed on the connecting strip 5 located on the lower side of the rear surface.

[0040] Specifically, when the external controller controls the extension of the electric push rod 602, the movable strip 1202 can be driven by the connecting rib plate 601. The movable strip 1202 can move in the slide groove 10 by the slider 1201. The insert plate 1203 can be inserted into the bottom fold position of the flat-bottomed eco-friendly bag. The movable strip 1202 drives the insert plate 1203 to move, thereby moving the bottom layer of flat-bottomed eco-friendly bags in the eco-friendly bag stack out of the irregular upright plate 1. The rubber strip 1204 flexibly contacts the eco-friendly bag, which can reduce the risk of bag breakage.

[0041] Furthermore, the auxiliary components 7 are arranged in a front-to-back array. The auxiliary components 7 include auxiliary rollers 701 and mounting grooves 702. The mounting grooves 702 are formed on the lower surface of the irregularly shaped vertical plate 1, and the auxiliary rollers 701 are rotatably mounted inside the mounting grooves 702.

[0042] Specifically, when the flat-bottomed eco-friendly bags at the bottom of the stack move out of the irregularly shaped upright plate 1, the flat-bottomed eco-friendly bags move on the auxiliary rollers 701, which can drive the auxiliary rollers 701 to rotate within the mounting groove 702, thereby reducing the friction of the flat-bottomed eco-friendly bags when they exit the stack.

[0043] Furthermore, the output component 8 includes a driven roller 801, a mounting plate 802, a driving roller 803, and a drive motor 804. The mounting plate 802 is respectively disposed on the irregularly shaped upright plates 1 on the left and right sides. The fixed disks 11 disposed at both ends of the driven roller 801 are connected to the mounting plate 802 through the clamping component 9. The driving roller 803 is rotatably mounted between the mounting plates 802. The drive motor 804 is disposed on the mounting plate 802, and the output shaft of the drive motor 804 is connected to the driving roller 803.

[0044] Furthermore, the clamping assembly 9 includes a movable column 901, a tension spring 902, a horizontal plate 903, and a movable block 904. The movable column 901 passes through the sliding hole of the horizontal plate 903 and connects to the movable block 904. The tension spring 902 is disposed between the horizontal plate 903 and the movable block 904. The movable column 901 is disposed in the middle of the tension spring 902. The horizontal plate 903 is disposed on the mounting plate 802. The movable block 904 is disposed on the fixed plate 11 and is disposed in the movable groove opened on the mounting plate 802.

[0045] Specifically, the drive motor 804 is connected to an external controller. When the drive motor 804 is running, it drives the rotation of the active roller 803. The flat bottom eco-friendly bag is output between the active roller 803 and the driven roller 801. The thickness of the flat bottom eco-friendly bag varies with different weights. The pressing component 29 can make the driven roller 801 adapt to flat bottom eco-friendly bags of different weights.

[0046] Flat-bottomed eco-friendly bags of different weights have different thicknesses. After the flat-bottomed eco-friendly bag enters between the active roller 803 and the driven roller 801, the flat-bottomed eco-friendly bag can push up the driven roller 801, thereby driving the movable block 904 to move upward, so that the tension spring 902 is under pressure. At the same time, the tension spring 902 can apply downward pressure to the driven roller 801, pressing the flat-bottomed eco-friendly bag tightly, ensuring the smooth output of the flat-bottomed eco-friendly bag.

[0047] It is worth noting that the drive motor 804 and the electric linear actuator 602 are connected to the input terminal of the external controller to ensure that the external controller can control the operation of the drive motor 804 and the electric linear actuator 602. The drive motor 804 can be a commonly available JGA25-370 DC geared motor, and the electric linear actuator 602 can be a commonly available TECHLINE TL10 (12V DC) small light-load electric linear actuator.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
