The bag pressing and shaping device includes a frame, a conveying mechanism, a pressure plate, and a linear drive mechanism. Under the action of the conveying mechanism, each bag of material can be transported to the shaping station in sequence. After one bag of material is transported to the shaping station, the linear drive mechanism can control the pressure plate to move closer to the bag of material.

Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical automated production technology, and in particular to a bag-pressing and shaping device and a labeling production line. Background Technology

[0002] In automated pharmaceutical manufacturing, labeling of bagged materials (such as materials packaged in woven bags) is often required. Because bagged materials are soft and have uneven surfaces after filling, direct labeling can easily cause wrinkles and poor adhesion, affecting the flatness and adhesion of the label. Therefore, before labeling, it is usually necessary to partially shape the surface of the bagged material to create a relatively flat labeling area.

[0003] Currently, the common method for shaping bags involves using a robotic arm to press and flatten the bagged material using a pressure plate at its end. While this method achieves a certain degree of surface shaping, the complex structure and high cost of the robotic arm itself significantly increase the cost of the labeling production line, making it difficult to control production costs. Furthermore, additional space needs to be reserved for the robotic arm's end effector when arranging it, resulting in a large footprint for the entire bag-pressing and shaping device, further increasing the cost of the labeling production line.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a bag-pressing and shaping device and a labeling production line to reduce the production cost of bagged materials during the labeling process.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The bag-pressing and shaping device includes:

[0008] frame;

[0009] A conveying mechanism is arranged horizontally on the frame and has a shaping station. The conveying mechanism is configured to convey multiple bagged materials so that each bagged material can pass through the shaping station in sequence.

[0010] A pressure plate is positioned above the shaping station;

[0011] A linear drive mechanism is arranged vertically and connected to the pressure plate. The linear drive mechanism is configured to drive the pressure plate to rise and fall vertically and press down the bagged material located at the shaping station.

[0012] Preferably, the pressure plate is provided with a pressure detection element, which is electrically connected to the linear drive mechanism and configured to detect the downward pressure on the bagged material when the pressure plate presses down on the bagged material.

[0013] Preferably, a plurality of buffer mechanisms are provided between the moving end of the linear drive mechanism and the pressure plate, and the plurality of buffer mechanisms are configured to buffer the downward pressure on the bagged material.

[0014] Preferably, the buffer mechanism includes:

[0015] A guide rod is vertically positioned between the moving end and the pressure plate;

[0016] A compression spring is sleeved on the guide rod, and both ends of the compression spring are connected to the moving end and the pressure plate, respectively.

[0017] Preferably, the linear drive mechanism includes:

[0018] The frame is located on one side of the machine frame;

[0019] A servo motor and a linear module connected to the servo motor, wherein the servo motor is configured to drive the slide of the linear module to move vertically up and down.

[0020] A connecting bracket is disposed on the slide table and connected to the pressure plate.

[0021] Preferably, the linear drive mechanism further includes a linear slide rail, which is disposed on the frame along the vertical direction, and the connecting frame is slidably disposed on the linear slide rail.

[0022] Preferably, the bag-pressing and shaping device further includes:

[0023] A pallet is used to carry the corresponding bagged material when the conveying mechanism transports the bagged material.

[0024] A return mechanism is arranged horizontally on the frame and below the conveying mechanism, and the return mechanism is configured to transport an empty pallet to the starting end of the conveying mechanism.

[0025] Preferably, the distance between the return mechanism and the conveying mechanism is adjustable.

[0026] Preferably, the bag-pressing and shaping device further includes a feeding mechanism, which is located at the starting end of the conveying mechanism and is configured to transport bagged materials to the conveying mechanism.

[0027] The feeding mechanism is electrically connected to the linear drive mechanism to transmit material information of the corresponding bagged material to the linear drive mechanism.

[0028] A labeling production line includes a labeling device and a bag-pressing and shaping device as described above, wherein the labeling device is located downstream of the linear drive mechanism.

[0029] The beneficial effects of this utility model are:

[0030] The bag-pressing and shaping device proposed in this utility model can sequentially transport each bagged material to the shaping station under the action of the conveying mechanism. After one bagged material is transported to the shaping station, the linear drive mechanism can control the pressure plate to move closer to the bagged material. As the pressure plate continues to press down, the shaping of a single bagged material can be completed. With the continuous transport of the conveying mechanism, the shaping of each bagged material can be performed continuously. Compared with a robot, the working path of the linear drive mechanism is in the vertical direction, and no additional space needs to be reserved during the layout, thereby reducing the space occupied by the bag-pressing and shaping device. Furthermore, using a linear drive mechanism instead of a complex multi-degree-of-freedom robot greatly simplifies the structure of the entire bag-pressing and shaping device, resulting in lower initial manufacturing costs and easier maintenance in the later stages.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] Please see Figures 1 to 3 This embodiment proposes a bag-pressing and shaping device, which includes a frame 1, a conveying mechanism 2, a pressing plate 3, and a linear drive mechanism 4. The conveying mechanism 2 is arranged horizontally on the frame 1 and has a shaping station. The conveying mechanism 2 is configured to convey multiple bagged materials 100 so that each bagged material 100 can pass through the shaping station in sequence. The pressing plate 3 is arranged above the shaping station. The linear drive mechanism 4 is arranged vertically and connected to the pressing plate 3. The linear drive mechanism 4 is configured to drive the pressing plate 3 to rise and fall vertically and press down the bagged materials 100 located at the shaping station.

[0045] Understandably, the conveying mechanism 2 can sequentially transport each bagged material 100 to the shaping station. The initial state of the bagged material 100 is as follows: Figure 1As shown in the large quadrilateral, after one of the bagged materials 100 is conveyed to the shaping station, the linear drive mechanism 4 can control the pressure plate 3 to move closer to the bagged material 100. As the pressure plate 3 continues to press down, the shaping of a single bagged material 100 can be completed. The state of the bagged material 100 after shaping is as follows. Figure 1 As shown in the small quadrilateral, with the continuous transport of the conveying mechanism 2, each bagged material 100 can be continuously shaped. Compared with the robot, the working path of the linear drive mechanism 4 is along the vertical direction, and no additional space needs to be reserved for movement when it is arranged, thereby reducing the space occupied by the bag pressing and shaping device. In addition, the use of the linear drive mechanism 4 to replace the complex multi-degree-of-freedom robot greatly simplifies the structure of the entire bag pressing and shaping device. Not only is the initial manufacturing cost low, but the later maintenance is also simpler, thereby reducing maintenance costs.

[0046] The conveying mechanism 2 is preferably a linear conveying structure such as a roller conveyor, belt conveyor or chain conveyor in the prior art. Here, a roller conveyor is used as an example. The motor of the roller conveyor is preferably a stepper motor in the prior art. The stepper motor is connected to a PLC controller (programmable logic controller). Under the action of the PLC controller, the number of rotations of the drive wheel connected to the motor can be accurately controlled, thereby accurately controlling the distance that a single bag of material 100 moves each time, so as to realize the intermittent conveying of the bag of material 100 by the roller conveyor.

[0047] It should be noted that when setting the number of rotations of the drive wheel, it should be ensured that any bagged material 100 can stay at the shaping station in order to facilitate the shaping of the bagged material 100.

[0048] Furthermore, a pressure detection element is provided on the pressure plate 3. The pressure detection element is electrically connected to the linear drive mechanism 4 and is configured to detect the downward pressure on the bagged material 100 when the pressure plate 3 presses down on the bagged material 100. It can be understood that when the pressure plate 3 comes into contact with the bagged material 100, the pressure plate 3 can apply a pressure to the bagged material 100. Correspondingly, the bagged material 100 can apply a reaction force to the pressure plate 3. This reaction force is equal in magnitude and opposite in direction to the downward pressure. Under the action of the pressure detection element, this self-reaction force can be detected, that is, the downward pressure can be detected. Under the action of the pressure detection element, damage to the material inside the bagged material 100 due to excessive downward pressure can be avoided.

[0049] Specifically, before shaping the bagged material 100, a threshold is set for the pressure detection element. When the pressure value reaches the threshold, the pressure detection element can send a signal to the linear drive mechanism 4. After receiving the signal, the linear drive mechanism 4 stops the pressing action of the pressure plate 3 and raises the pressure plate 3 to the initial position so that the bagged material 100 can be continuously transported.

[0050] The pressure detection element is preferably a pressure sensor in the prior art, the specific structure and use of which are well known to those skilled in the art and will not be described in detail here.

[0051] Furthermore, a plurality of buffer mechanisms 5 are provided between the moving end of the linear drive mechanism 4 and the pressure plate 3. These buffer mechanisms 5 are configured to buffer the downward pressure on the bagged material 100. Under the action of the buffer mechanisms 5, rigid contact between the pressure plate 3 and the bagged material 100 can be avoided, thereby preventing damage to the material inside the bagged material 100.

[0052] Preferably, there are four buffer mechanisms 5, which are arranged at the four corners of the pressure plate 3. This arrangement can prevent the pressure plate 3 from shifting when it comes into contact with the bagged material 100, thereby ensuring the shaping quality.

[0053] Specifically, the buffer mechanism 5 includes a guide rod 51 and a compression spring 52. The guide rod 51 is vertically positioned between the moving end and the pressure plate 3. The compression spring 52 is sleeved on the guide rod 51, and its two ends are connected to the moving end and the pressure plate 3, respectively. It is understood that when the pressure plate 3 contacts the bagged material 100, the compression spring 52 is compressed under the action of the reaction force, thereby buffering the reaction force and preventing damage to the material inside the bagged material 100. Furthermore, the guide rod 51 prevents the compression spring 52 from shifting during compression and reset, ensuring the shaping quality of the subsequent bagged material 100.

[0054] The guide rod 51 is preferably a telescopic rod in the prior art. The two ends of the telescopic rod are fixed to the moving end and the pressure plate 3 by screws, respectively. The telescopic rod can deform synchronously when the compression spring 52 deforms, so as to ensure the stability of the pressure plate 3 when it moves.

[0055] In some other feasible embodiments, the guide rod 51 is a straight rod, with one end fixed to either the moving end or the pressure plate 3, and the other end passing through the other, so that the moving end or the pressure plate 3 can slide and connect with the straight rod as a slider.

[0056] In this embodiment, the linear drive mechanism 4 includes a frame 41, a servo motor 42, a linear module 43, and a connecting frame 44. The frame 41 is disposed on one side of the frame 1. The servo motor 42 and the linear module 43 are connected to the servo motor 42 for transmission. The servo motor 42 is configured to drive the slide of the linear module 43 to move vertically. The connecting frame 44 is disposed on the slide and connected to the pressure plate 3. It can be understood that the connecting frame 44 can serve as the moving end of the linear drive mechanism 4 and is connected to the pressure plate 3. Under the action of the servo motor 42, it can drive the slide of the linear module 43 to move vertically, thereby driving the connecting frame 44 and the pressure plate 3 to move vertically. The servo motor 42 can quickly identify the signal transmitted by the pressure detection element and react quickly, thereby further preventing the pressure plate 3 from damaging the material.

[0057] Furthermore, the linear drive mechanism 4 also includes a linear slide rail 45, which is vertically mounted on the frame 41, and the connecting frame 44 is slidably mounted on the linear slide rail 45. It is understood that the connecting frame 44 acts as a cantilever on the slide table and can be slidably mounted on the linear slide rail 45. Under the action of the linear slide rail 45, it can share the load on the slide table, thereby improving the service life of the linear module 43 and reducing maintenance costs.

[0058] In this embodiment, the bag-pressing and shaping device also includes a feeding mechanism, which is located at the starting end of the conveying mechanism 2. The feeding mechanism is configured to transport the bagged material 100 to the conveying mechanism 2. Under the action of the feeding mechanism, the bagged material 100 can be transported onto the conveying mechanism 2 for subsequent shaping and labeling.

[0059] During normal operation, the surface of some bagged materials 100 is uneven and therefore requires shaping, while the surface of other bagged materials 100 is relatively smooth and does not require shaping. Therefore, in this embodiment, the feeding mechanism can identify the corresponding material information during the handling of the bagged materials 100, and the feeding mechanism is electrically connected to the linear drive mechanism 4 to transmit the material information of the corresponding bagged materials 100 to the linear drive mechanism 4. This configuration reduces the number of times the linear drive mechanism 4 is used, thereby extending its service life and reducing production costs.

[0060] Specifically, the feeding mechanism includes a robotic arm and a vision recognition device located at the starting end of the conveying mechanism 2. Since the robotic arm is located at the starting end of the conveying mechanism 2, it will not occupy additional space in the entire bag-pressing and shaping device. The vision recognition device is located at the end effector of the robotic arm and is used to identify the flatness of the bagged material 100. The vision recognition device is preferably a 3D camera in the prior art. After the 3D camera identifies the flatness of the corresponding bagged material 100, it can transmit a signal to the linear drive mechanism 4. When the corresponding bagged material 100 is conveyed to the shaping station, the pressing plate 3 does not perform a pressing action.

[0061] Because the surface of the material is uneven after filling, the conveying mechanism 2 is prone to deviation during the conveying process. This not only makes subsequent shaping difficult, but also makes it easy for the bagged material 100 to get stuck in the gap of the conveying mechanism 2, causing a safety accident.

[0062] Based on the above, in this embodiment, the bag-pressing and shaping device further includes a tray 6, which is used to support the corresponding bagged material 100 when the conveying mechanism 2 conveys the bagged material 100. It can be understood that, under the action of the tray 6, the conveying mechanism 2 and the bagged material 100 can be isolated to avoid deviation of the bagged material 100 during the conveying process.

[0063] It should be noted that in this embodiment, the bagged material 100 and the pallet 6 are supplied together. That is, during the feeding process, the feeding mechanism can transport the pallet 6 and the corresponding bagged material 100 together to the conveying mechanism 2. In some other feasible embodiments, the bagged material 100 may also be supplied separately. That is, during the feeding process, the feeding mechanism first places the bagged material 100 in the pallet 6, and then transports the pallet 6 and the corresponding bagged material 100 together to the conveying mechanism 2.

[0064] Furthermore, after the bagged material 100 is labeled, it needs to be unloaded. At this time, the bagged material 100 is separated from the tray 6. To enable the tray 6 to be reused, in this embodiment, the bag-pressing and shaping device also includes a return mechanism 7. The return mechanism 7 is arranged horizontally on the frame 1 and is located below the conveying mechanism 2. The return mechanism 7 is configured to convey the empty tray 6 to the starting end of the conveying mechanism 2. It can be understood that after the bagged material 100 is unloaded, the tray 6 is recycled and conveyed to the starting end through the return mechanism 7, so that the staff can send it back to the previous process, or so that the feeding mechanism can place the bagged material 100 on the tray 6.

[0065] The return material mechanism 7 is preferably a linear conveying structure such as a roller conveyor, belt conveyor or chain conveyor in the prior art, and no specific limitation is made here.

[0066] Furthermore, the distance between the return mechanism 7 and the conveying mechanism 2 is adjustable. It is understandable that the pallet 6 is often stacked during the recycling process, and adjusting the distance between the conveying mechanism 2 and the return mechanism 7 can accommodate different stacking heights.

[0067] For example, the frame 1 is provided with multiple threaded holes in the vertical direction. The return material mechanism 7 and the conveying mechanism 2 are both fixed to the frame 1 by bolts. According to different production needs, the return material mechanism 7 and the conveying mechanism 2 are adjusted to face different threaded holes so as to adjust the distance between them.

[0068] Based on the above, this embodiment proposes a labeling production line, which includes a labeling device and a bag-pressing and shaping device. The labeling device is located downstream of the linear drive mechanism 4. It can be understood that the conveying mechanism 2 is the conveyor line of the labeling production line. After the pressure plate 3 shapes the bagged material 100, it can be conveyed to the labeling device under the action of the conveying mechanism 2 and the labeling is completed. This arrangement can further reduce the space occupied by the labeling production line, thereby further reducing the production cost during the labeling process.

[0069] It should be noted that the labeling device is preferably a labeling machine used in the prior art for labeling bagged materials 100, and no specific restrictions are made here.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
