Description

Technical Field

[0001] The utility model relates to the field of a feeding system of a packaging machine, in particular to a reversing transfer device and a liner feeding system. Background Art

[0002] During drug production, the drugs discharged from the previous process are placed in the same direction. When the next process requires the drugs to be placed in another direction, the posture of the drugs needs to be adjusted. For example, the drugs discharged from the previous process are placed vertically (parallel to the discharge direction). When the next process requires the drugs to be placed horizontally (perpendicular to the discharge direction), the drugs need to be rotated 90°.

[0003] The existing transfer mechanism needs to realize the actions of picking up, transferring and releasing materials, so the structure of the transfer mechanism itself is relatively complicated. If a reversing structure is added to the transfer mechanism, the mass of the transfer mechanism will be further increased. For example, a reversing transfer device with patent number CN219313972U first requires a drive to realize the opening and closing of the material picking part, and secondly, a connecting rod structure is required to realize the synchronous rotation of the material picking part for reversing. The entire reversing transfer device is bulky and inconvenient to operate. When the transfer device needs to be replaced according to different specifications, a large amount of human resources are consumed, and costs and energy consumption are also increased. Utility Model Content

[0004] The purpose of the utility model is to provide a reversing transfer device and a lining feeding system, which solves the problems that the reversing transfer device in the prior art is bulky, inconvenient to operate, consumes a lot of human resources when replacing the transfer device according to different specifications, and also increases costs and energy consumption.

[0005] The utility model is implemented in this way. A reversing transfer device includes a frame, a linear drive arranged on the frame, a synchronous belt and a plurality of rotatable material picking members. The linear drive is connected to the material picking members through a synchronous belt, and the linear drive action is used to drive the material picking members to rotate.

[0006] In the prior art, the structure of the transfer mechanism itself is relatively complex. When reversing is required, a device with a reversing function needs to be added to the transfer mechanism, which makes the overall transfer mechanism more bulky. Therefore, when designing the reversing device, it is necessary to consider how to reduce the mass of the transfer mechanism. In the present utility model, in order to achieve synchronous rotation and reversing of the material picking part, it is mainly connected to the material picking part through a synchronous belt, and then a linear drive drives the synchronous belt to move to achieve rotation and reversing of the material picking part. Compared with the connecting rod mechanism used for reversing in the prior art, the reversing structure in the present utility model is simpler and lighter, and the overall mass of the reversing transfer device is effectively reduced.

[0007] A further technical solution of the utility model is that: the material taking member is provided with a synchronous wheel meshing with the synchronous belt.

[0008] A synchronous wheel is provided on the material picking piece, and a synchronous belt sleeve is arranged on the outside of the synchronous wheel and meshes with the synchronous wheel. Under the action of linear drive, the synchronous belt moves to drive the synchronous wheel to rotate, and the material picking piece connected to the synchronous wheel also rotates synchronously, so that multiple material picking pieces can achieve synchronous reversing.

[0009] A further technical solution of the utility model is: the linear drive is a cylinder, and the linear drive is placed on the side of the frame and connected to the synchronous belt through a clamping plate.

[0010] The structure of the cylinder is simpler and lighter than that of the motor; the linear drive is placed on the side of the frame and connected to the synchronous belt through a splint, which can reduce the space above the synchronous belt, thereby reducing the height of the frame, and then reducing the mass and volume of the frame, further reducing the mass of the reversing transfer device.

[0011] Since the linear drive is on the side, it is necessary to transmit the linear drive to the synchronous belt. The transmission teeth of the synchronous belt are on the inside, and the power of the linear drive is transmitted to the synchronous belt through the clamping plate.

[0012] A further technical solution of the utility model is that a plurality of tensioning wheels for tensioning the synchronous belt are arranged on the frame.

[0013] The tensioning wheel effectively ensures that the synchronous belt is in a tensioned state, ensuring the meshing effect between the synchronous belt and the synchronous wheel on the material picking part.

[0014] A further technical solution of the utility model is that: the linear drive is provided with an adjusting member for adjusting the linear drive stroke.

[0015] The linear drive comprises a fixed part connected to the frame and a movable end for driving the synchronous belt to move, and an adjusting member is arranged on the fixed part for limiting the movable range of the movable end.

[0016] A further technical solution of the utility model is: a suction cup is provided on the material taking piece, a ventilation module for connecting with an air source is provided on the frame, and the ventilation module is connected with the suction cup for taking and placing materials.

[0017] The motor-driven clamping jaw method in the prior art not only occupies a large space but also increases the mass due to the setting of the motor. In the utility model, a suction cup is provided on the material picking piece, and the suction cup is connected to the ventilation module through an air pipe, and the air source may not be provided on the reversing transfer device, thereby reducing the space occupied and the mass of the reversing transfer device.

[0018] The utility model also provides a lining feeding system, including a feeding mechanism and a material bin, a material taking mechanism and a glue dispensing mechanism arranged in sequence along the material feeding direction, the material taking mechanism is used to take out the material in the material bin, the feeding mechanism is used to transfer the material on the material taking mechanism to the box body of the conveying mechanism after passing through the glue dispensing mechanism, and the feeding mechanism includes a first driving component and the reversing transfer device arranged on the driving component.

[0019] In the existing method, the long side of the liner is placed at the bottom of the silo, that is, it is placed horizontally, which occupies a large horizontal space of the silo. In the utility model, the long side of the liner is placed against the side of the silo, that is, it is placed vertically, which reduces the horizontal space occupied by the silo. For a silo with the same floor space, the liner placement method in the utility model can accommodate more liners; however, this method will cause the liner to be perpendicular to the direction of the box body, so before the liner is placed in the box body, it is necessary to rotate the liner by a certain angle to ensure that the liner is accurately placed in the box body; therefore, the liner feeding system adopts the layout of the utility model to effectively solve the problem of floor space without affecting the liner feeding.

[0020] A further technical solution of the utility model is: an air source is provided on the driving component, a ventilation module detachably connected to the air source is provided on the reversing transport device, and the driving component is detachably connected to the reversing transport device.

[0021] The driving assembly is detachably connected to the reversing transfer device, which can meet the needs when parts of different specifications need to be replaced; since the reversing transfer device needs to be replaced, its weight should be reduced as much as possible to facilitate replacement. In the utility model, since the air source of the material picking part that sucks the liner is installed on the driving assembly, the material picking part and the air source can be connected through the ventilation module and the air pipe; the structural components on the reversing transfer device are reduced, and the quality is reduced.

[0022] A further technical solution of the utility model is: the material taking mechanism comprises a second driving assembly and a forming fixture arranged on the second driving assembly.

[0023] Regarding the loading of the lining, the lining is formed synchronously during the transportation process, which effectively improves the transportation efficiency.

[0024] A further technical solution of the utility model is: the second driving assembly includes a movable first mechanical arm, a movable second mechanical arm connected to the first mechanical arm, and a movable connecting arm placed on the second mechanical arm, and the forming fixture is placed on the connecting arm.

[0025] When a standard part needs to be replaced, a second drive component with one degree of freedom cannot meet the demand; therefore, after replacing the standard part, the standard part needs to stay in the set position, which requires a robotic arm with at least two degrees of freedom; at the same time, the design of two robotic arms reduces space occupancy.

[0026] Beneficial effects of the present invention: In the prior art, the structure of the transfer mechanism itself is relatively complex. When reversing is required, a device with a reversing function needs to be added to the transfer mechanism, which makes the overall transfer mechanism more bulky. Therefore, when designing the reversing device, it is necessary to consider how to reduce the mass of the transfer mechanism; in the present invention, in order to achieve synchronous rotation and reversing of the material picking part, it is mainly connected to the material picking part through a synchronous belt, and then a linear drive drives the synchronous belt to move to achieve rotation and reversing of the material picking part; compared with the connecting rod mechanism used for reversing in the prior art, the reversing structure in the present invention is simpler and lighter, and the overall mass of the reversing transfer device is effectively reduced.

[0027] In the existing method, the long side of the liner is placed at the bottom of the silo, that is, it is placed horizontally, which occupies a large horizontal space of the silo. In the utility model, the long side of the liner is placed against the side of the silo, that is, it is placed vertically, which reduces the horizontal space occupied by the silo. For a silo with the same floor space, the liner placement method in the utility model can accommodate more liners; however, this method will cause the liner to be perpendicular to the direction of the box body, so before the liner is placed in the box body, it is necessary to rotate the liner by a certain angle to ensure that the liner is accurately placed in the box body; therefore, the liner feeding system adopts the layout of the utility model to effectively solve the problem of floor space without affecting the liner feeding.

[0050] Embodiment 1:

[0051] Figure 1-5 A reversing transfer device is shown, including a frame 321, a linear drive 323 arranged on the frame 321, a synchronous belt 324 and a plurality of rotatable material picking members 6, wherein the linear drive 323 is connected to the material picking members 6 via the synchronous belt 324, and the linear drive 323 is used to drive the material picking members 6 to rotate.

[0052] In this embodiment, the material picking member 6 is provided with a synchronous wheel 61 meshing with the synchronous belt 324 .

[0053] A synchronous wheel is provided on the material picking piece, and a synchronous belt sleeve is arranged on the outside of the synchronous wheel and meshes with the synchronous wheel. Under the action of linear drive, the synchronous belt moves to drive the synchronous wheel to rotate, and the material picking piece connected to the synchronous wheel also rotates synchronously, so that multiple material picking pieces can achieve synchronous reversing.

[0054] In this embodiment, teeth are provided on the inner side of the synchronous belt, and teeth meshing with the inner side of the synchronous belt are provided on the outer periphery of the synchronous wheel.

[0055] In this embodiment, the linear drive 323 is a cylinder, and the linear drive 323 is placed on the side of the frame 321 and connected to the synchronous belt 61 through a clamping plate 326 .

[0056] The structure of the cylinder is simpler and lighter than that of the motor; the linear drive is placed on the side of the frame and connected to the synchronous belt through a splint, which can reduce the space above the synchronous belt, thereby reducing the height of the frame, and then reducing the mass and volume of the frame, further reducing the mass of the reversing transfer device.

[0057] Since the linear drive is on the side, it is necessary to transmit the linear drive to the synchronous belt. The transmission teeth of the synchronous belt are on the inside, and the power of the linear drive is transmitted to the synchronous belt through the clamping plate.

[0058] In this embodiment, one side of the splint is provided with a rack that meshes with the transmission teeth on the synchronous belt. The side of the splint provided with the rack is connected to the movable end of the linear drive and can form a gap for the synchronous belt to pass through. The transmission teeth on the inner side of the synchronous belt can mesh with the rack of the splint to realize transmission.

[0059] In this embodiment, a plurality of tensioning wheels 325 for tensioning the synchronous belt 324 are disposed on the frame 321 .

[0060] The tensioning wheel effectively ensures that the synchronous belt is in a tensioned state, ensuring the meshing effect between the synchronous belt and the synchronous wheel on the material picking part.

[0061] In this embodiment, multiple material picking parts are provided with synchronous wheels, and multiple material picking parts are arranged in a straight line, so multiple synchronous wheels are also on the same straight line. In order to ensure that multiple synchronous wheels can smoothly rotate synchronously through the synchronous belt, tension wheels are provided between the synchronous wheels. The tension wheel is placed outside the synchronous belt.

[0062] In this embodiment, the linear drive 323 is provided with an adjusting member 7 for adjusting the stroke of the linear drive 323 .

[0063] The linear drive comprises a fixed part connected to the frame and a movable end for driving the synchronous belt to move, and an adjusting member is arranged on the fixed part for limiting the movable range of the movable end.

[0064] In this embodiment, the slider 8 is connected to the movable end of the linear drive, and the slider is placed between the fixed parts of the linear drive. The adjusting member is threadedly connected to the fixed part, and the movable range of the slider is between the two adjusting members. Therefore, the stroke of the linear drive can be adjusted by adjusting the position of the adjusting member on the fixed part.

[0065] In this embodiment, a suction cup is provided on the material taking member 6, and a ventilation module 9 for connecting to an air source is provided on the frame 321. The ventilation module 9 is connected to the suction cup for taking and placing materials.

[0066] The motor-driven clamping jaw method in the prior art not only occupies a large space but also increases the mass due to the setting of the motor. In the utility model, a suction cup is provided on the material picking piece, and the suction cup is connected to the ventilation module through an air pipe, and the air source may not be provided on the reversing transfer device, thereby reducing the space occupied and the mass of the reversing transfer device.

[0067] In this embodiment, the ventilation module is detachable from the air source to meet the needs of replacing different reversing transfer devices for parts of different specifications. At the same time, the cylinder used in the linear drive of the utility model can also be connected to the ventilation module for cylinder drive.

[0068] Working principle of this embodiment: In the prior art, the structure of the transfer mechanism itself is relatively complex. When reversing is required, a device with a reversing function needs to be added to the transfer mechanism, which makes the overall transfer mechanism more bulky. Therefore, when designing the reversing device, it is necessary to consider how to reduce the mass of the transfer mechanism; in the present utility model, in order to achieve synchronous rotation and reversing of the material picking part, it is mainly connected to the material picking part through a synchronous belt, and then a linear drive drives the synchronous belt to move to achieve rotation and reversing of the material picking part; compared with the connecting rod mechanism used for reversing in the prior art, the reversing structure in the present utility model is simpler and lighter, and the overall mass of the reversing transfer device is effectively reduced.

[0069] Embodiment 2:

[0070] like Figure 1-10 A lining feeding system shown in the figure comprises a feeding mechanism 3 and a silo 1, a material taking mechanism 2 and a glue dispensing mechanism 5 which are arranged in sequence along the material feeding direction. The material taking mechanism 2 is used to take out the material in the silo 1, and the feeding mechanism 3 is used to transfer the material on the material taking mechanism 2 to the box body of the conveying mechanism 4 after passing through the glue dispensing mechanism 5. The feeding mechanism 3 comprises a first driving component 31 and a reversing transfer device 32 as described in Example 1 which is arranged on the driving component 31.

[0071] In this embodiment, the driving component 31 is provided with an air source, the reversing transport device 32 is provided with a ventilation module 9 detachably connected to the air source, and the driving component 31 and the reversing transport device 32 are detachably connected.

[0072] The driving assembly is detachably connected to the reversing transfer device, which can meet the needs when parts of different specifications need to be replaced; since the reversing transfer device needs to be replaced, its weight should be reduced as much as possible to facilitate replacement. In the utility model, since the air source of the material picking part that sucks the liner is installed on the driving assembly, the material picking part and the air source can be connected through the ventilation module and the air pipe; the structural components on the reversing transfer device are reduced, and the quality is reduced.

[0073] In this embodiment, the material taking mechanism 2 includes a second driving assembly 21 and a forming fixture 22 disposed on the second driving assembly 21 .

[0074] Regarding the loading of the lining, the lining is formed synchronously during the transportation process, which effectively improves the transportation efficiency.

[0075] In this embodiment, the forming fixture includes a fixed seat 221 and a movable seat 222 arranged on both sides of the fixed seat 221. The fixed seat 221 and the movable seat 222 are provided with a fixing mechanism for fixing the lining, and a liftable bending component 223 is provided between the fixed seat 221 and the movable seat 222.

[0076] The lining is placed on a fixed seat and a movable seat, and then fixed by a fixing mechanism. During molding, the lining is folded along the crease by moving the movable seat. During this molding process, a lifting and lowering bending component is arranged between the fixed seat and the movable seat to ensure that the lining is folded in the correct direction. The lining molding has a high qualified rate, which ensures the smooth progress of subsequent processes.

[0077] In this embodiment, a guide slope 226 is provided between the fixed seat 221 and the movable seat 222 . The guide slope 226 cooperates with the bending assembly 223 . The movable seat 22 can move in a direction close to or away from the fixed seat 221 so that the bending assembly 223 can be raised and lowered along the guide slope 226 .

[0078] The guide slope is arranged between the fixed seat and the movable seat. During the movement of the movable seat, the bending assembly can move along the guide slope, thereby realizing the lifting and lowering of the bending assembly, eliminating the lifting and lowering drive of the bending assembly, making the design of the entire forming fixture more reasonable and the forming fixture occupies less space.

[0079] In this embodiment, the fixing mechanism includes a baffle 224 and a pressing member 225, wherein the baffle 224 is placed outside the fixed seat 221 and the movable seat 222, and the pressing member 225 is placed above the fixed seat 221 and / or the movable seat 222. The fixing mechanism partially limits the surroundings and the upper and lower parts of the liner, and fixes the part that does not fold during the liner molding; it ensures that the liner will not be displaced during the liner molding, and ensures the qualified rate of the liner molding. The pressing member can be turned over to prevent the liner from entering the molding fixture to form interference.

[0080] In this embodiment, the second driving assembly 21 includes a movable first robotic arm 211 , a movable second robotic arm 212 connected to the first robotic arm 211 , and a movable connecting arm 213 placed on the second robotic arm 212 , and the molding fixture 22 is placed on the connecting arm 213 .

[0081] When a standard part needs to be replaced, a second drive component with one degree of freedom cannot meet the demand; therefore, after replacing the standard part, the standard part needs to stay in the set position, which requires a robotic arm with at least two degrees of freedom; at the same time, the design of two robotic arms reduces space occupancy.

[0082] The working principle of this embodiment: the long side of the existing liner is placed at the bottom of the silo for placement of the liner, that is, it is placed horizontally, which occupies a large lateral space of the silo. In the utility model, the long side of the liner is placed against the side of the silo, that is, it is placed vertically, which reduces the lateral space occupied by the silo. For a silo with the same floor space, the liner placement method in the utility model can accommodate more liners; however, this method will cause the liner to be perpendicular to the direction of the box body, so before placing the liner into the box body, the liner needs to be rotated a certain angle to ensure that the liner is accurately placed in the box body; therefore, the liner feeding system adopts the layout of the utility model to effectively solve the problem of floor space without affecting the liner feeding.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
