Technical Field

[0001] This invention relates to the field of glass production equipment technology, specifically to an adaptive large-size pharmaceutical glass bottle stacking fixture. Background Technology

[0002] In the production of large-size pharmaceutical glass bottles, in order to reduce packaging costs, it is recommended to adopt the method of direct stacking of glass bottles for product packaging and storage.

[0003] Chinese Patent Application No. 201820582326.3 discloses a glass bottle palletizing device, including a robotic arm, a connecting frame, a mounting plate, and a tray. The robotic arm is connected to the connecting frame via a connecting rod. The mounting plate is positioned below the connecting frame and is bolted to the connecting frame.

The bottle clamping assembly includes a finger cylinder and a bottle clamping plate, with the bottle clamping plate connected to the finger cylinder. This utility model's glass bottle palletizing device has a reasonable structural design, high palletizing efficiency, low equipment cost, low labor intensity, and ensures stable and reliable stacking of glass bottles.

[0004] In the aforementioned patent, multiple sets of finger cylinders are used to drive the bottle clamping plate to clamp and move the glass bottle. However, the multi-finger cylinder drive makes the device too expensive. The device can only clamp the glass bottle and cannot effectively clamp and place the tray, resulting in mediocre performance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive large-size pharmaceutical glass bottle whole-layer stacking fixture, which solves the problems of excessively high cost due to multi-finger cylinder drive, the inability of the device to effectively grip and place the trays, and the generally poor performance of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive large-size pharmaceutical glass bottle stacking fixture, comprising a robotic arm, with an X-shaped mounting frame connected to the lower part of one end of the robotic arm via a shaft. Limiting plates are vertically connected between the two ends and the other two ends of the mounting frame, with the two limiting plates symmetrically arranged.

A gripping reinforcement assembly is provided on one side of the gripping assembly. The adaptive large-size pharmaceutical glass bottle stacking fixture also includes a gripping anti-drop assembly for preventing the glass bottles from falling and breaking.

[0007] The clamping assembly includes a limiting seat rotatably disposed between two limiting plates. The upper part of the limiting seat is provided with several through slots at equal intervals. A double-threaded screw is rotatably disposed in each through slot. The double-threaded screws are connected to each other by a shaft. A palletizing servo motor for driving the rotation of each double-threaded screw is installed on one side of the limiting seat. A moving block is screwed to both ends of each double-threaded screw. The lower end of the moving block extends out of the through slot and is connected to a clamping plate. An L-shaped clamping block is provided on the upper side of the moving block on both sides. The two L-shaped clamping blocks are arranged opposite each other.

[0008] Preferably, the threads on the outer sides of the two ends of the double-threaded screw are opposite to each other, and the moving blocks on the outer sides of the two ends of the double-threaded screw are respectively adapted to the two types of threads.

[0009] Preferably, the clamping and reinforcing assembly includes a housing seat disposed at the lower edge of one side of the limiting seat. The side of the housing seat near the clamping assembly is configured with an opening located at the bottom of the limiting seat. A rotating shaft is rotatably disposed inside the housing seat, and a reinforcing servo motor for driving the rotating shaft is installed at one end of the housing seat. Several double-threaded teeth are equidistantly disposed on the outside of the rotating shaft. The double-threaded teeth are opposite to each other. Two nut sleeves are symmetrically screwed onto the outside of the rotating shaft at each double-threaded tooth location. The two nut sleeves are respectively adapted to the two types of thread teeth on the double-threaded teeth. A reinforcing rod is disposed on one side of each nut sleeve. The end of the reinforcing rod away from the nut sleeve extends out of the opening on the housing seat. A strip groove is disposed on one side of each clamping plate. The end of each reinforcing rod away from the nut sleeve passes through the strip groove on each clamping plate and is laterally slidably connected to the clamping plate.

[0010] Preferably, the clamping and anti-drop assembly includes guide rods respectively connected to the bottom of both ends of the housing base. A movable plate is longitudinally slidably sleeved between the two guide rods. A drive servo motor is installed on one side of the movable plate, and a limit cylinder is horizontally connected to the other side of one end of the movable plate. A movable sleeve is laterally slidably sleeved on one side of the limit cylinder. A movable rod is horizontally connected to one side of the movable sleeve. The output shaft of the drive servo motor is connected to a threaded rod inside the limit cylinder. A nut block corresponding to the position of the movable sleeve is screwed onto the outside of the threaded rod. The two ends of the nut block are respectively connected to the inner side walls of the movable sleeve. Limit grooves are provided on both sides of the limit cylinder.

A connecting rod is hinged to the side of the moving seat away from the housing base. The side of the connecting rod away from the moving seat is hinged to one side of the protrusion.

[0013] This invention provides an adaptive stacking fixture for large-size pharmaceutical glass bottles, which has the following advantages compared with the prior art:

[0014] 1. This adaptive large-size pharmaceutical glass bottle whole-layer palletizing fixture uses a palletizing servo motor instead of a multi-finger cylinder drive, which greatly reduces the cost of the device. It can clamp multiple sets of glass bottles at one time. Under the action of the rotary cylinder, the clamping components can be rotated, so that the two L-shaped clamps can clamp the trays used to place the glass bottles at intervals. The structure is compact, thus making the use of this adaptive layer palletizing device better.

[0015] 2. This adaptive large-size pharmaceutical glass bottle stacking fixture, through the setting of clamping and reinforcement components, can drive each reinforcement rod to move under the operation of the reinforcement servo motor after the glass bottle is clamped, thereby performing a secondary clamping operation on the glass bottle, so that the bottle mouth is clamped in all four directions, ensuring the clamping firmness and making it less likely for the glass bottle to fall.

[0016] 3. This adaptive large-size pharmaceutical glass bottle stacking fixture, by setting up a gripping and anti-drop component, can unfold the support cloth when the glass bottles are being gripped and transported, under the operation of the driven servo motor, so as to support the bottom of each glass bottle and prevent the glass bottles from falling and breaking. When the glass bottles are being loaded and unloaded, the automatic winding function of the spiral spring can be used to store the support cloth, so that it does not hinder the loading and unloading of glass bottles.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 This invention provides four technical solutions:

[0025] Example 1

[0026] Please see Figure 1 In this embodiment of the invention, an adaptive large-size pharmaceutical glass bottle stacking fixture includes a robotic arm 1. One end of the robotic arm 1 is connected to an X-shaped mounting frame 2 via a shaft. Limiting plates 3 are vertically connected between the two ends and the other two ends of the mounting frame 2. The two limiting plates 3 are symmetrically arranged. A gripping component 4 is rotatably arranged between the lower sides of the two limiting plates 3. A gripping reinforcement component 6 is arranged on one side of the gripping component 4. The adaptive large-size pharmaceutical glass bottle stacking fixture also includes a gripping anti-drop component 7 for preventing the glass bottles from falling and breaking.

[0027] Please see Figure 2In this embodiment of the invention, the clamping component 4 includes a limiting seat 41 rotatably disposed between two limiting plates 3. The upper part of the limiting seat 41 is provided with a plurality of through slots 42 at equal intervals. A double-threaded screw 43 is rotatably disposed in each through slot 42. The double-threaded screws 43 are connected to each other by a shaft. A palletizing servo motor 44 for driving the rotation of each double-threaded screw 43 is installed on one side of the limiting seat 41. A moving block 45 is threadedly screwed to both ends of each double-threaded screw 43. The lower end of the moving block 45 extends out of the through slot 42 and is connected to a clamping plate 46.

[0028] Please see Figure 2 In this embodiment of the invention, the threads on the outer ends of the double-threaded screw 43 are opposite to each other, and the movable blocks 45 on the outer ends of the double-threaded screw 43 are respectively adapted to the two types of threads. When the double-threaded screw 43 rotates, the two movable blocks 45 move in opposite directions, thereby enabling the clamping plate 46 to clamp the glass bottle.

[0029] In the above scheme, the robotic arm 1 is raised and lowered by an external drive device, so that the gripping component 4 moves to the position of the glass bottle, so that the bottle mouth of each glass bottle is located between the two clamping plates 46. Then, the palletizing servo motor 44 drives the double-threaded screw 43 to rotate. Since the two threads on the double-threaded screw 43 are opposite to each other, the two moving blocks 45 will move in opposite directions, so that the two moving blocks 45 move relative to each other, thus clamping the bottle mouth of the glass bottle.

[0030] Example 2 differs from Example 1 in that:

[0031] Please see Figure 1 and Figure 3 In this embodiment of the invention, the clamping and reinforcing component 6 includes a housing seat 61 disposed at the lower edge of one side of the limiting seat 41. The side of the housing seat 61 near the clamping component 4 is configured with an opening located at the bottom of the limiting seat 41. A rotating shaft 62 is rotatably disposed inside the housing seat 61, and a reinforcing servo motor 63 for driving the rotating shaft 62 to rotate is installed at one end of the housing seat 61. Several double-threaded teeth are equidistantly disposed on the outside of the rotating shaft 62. The double-threaded teeth are opposite to each other. Two nut sleeves 64 are symmetrically screwed onto the outside of the rotating shaft 62 at each double-threaded tooth location. The two nut sleeves 64 are respectively adapted to the two types of thread teeth on the double-threaded teeth. A reinforcing rod 65 is disposed on one side of each of the two nut sleeves 64. The end of the reinforcing rod 65 away from the nut sleeve 64 extends out of the opening on the housing seat 61. A strip groove is disposed on one side of each clamping plate 46. The end of each reinforcing rod 65 away from the nut sleeve 64 passes through the strip groove on each clamping plate 46 and is laterally slidably connected to the clamping plate 46.

[0032] The space formed between each pair of reinforcing rods 65 and each pair of clamping plates 46 is the position where glass bottles need to be clamped, so that individual glass bottles can be stacked.

[0033] In the above scheme, under the operation of the reinforcement servo motor 63, the two nut sleeves 64 at the double thread can move, thereby driving the two reinforcement rods 65 to move. Since the two double threads are opposite to each other, the two reinforcement rods 65 can clamp the other two sides of the bottle mouth, ensuring the firmness of the glass bottle clamping and making it less likely to fall off.

[0034] Example 3 differs from Example 1 in that:

[0035] Please see Figure 1 and Figure 4-5 In this embodiment of the invention, the clamping anti-drop component 7 includes guide rods 71 ​​respectively connected to the bottom of both ends of the housing base 61. A movable plate 72 is longitudinally slidably sleeved between the two guide rods 71. A drive servo motor 74 is mounted on one side of the movable plate 72, and a limiting cylinder 75 is horizontally connected to the other side of one end of the movable plate 72. A movable sleeve 76 is laterally slidably sleeved on the outside of one end of the limiting cylinder 75. A movable rod 77 is horizontally connected to one side of the movable sleeve 76. A threaded rod 78 is connected to the output shaft of the drive servo motor 74 inside the limiting cylinder 75. The part is threadedly connected to a nut block 79 corresponding to the position of the movable sleeve 76. The two ends of the nut block 79 are respectively connected to the inner side walls of the movable sleeve 76. Limiting grooves are provided on both sides of the limiting cylinder 75. The two ends of the nut block 79 pass through the two limiting grooves and are laterally slidably connected to the limiting cylinder 75. An opening groove is provided on the side of the movable plate 72 away from the drive servo motor 74, located between the two guide rods 71. A limiting shaft 710 is rotatably installed in the opening groove. A support cloth 711 is wound around the outside of the limiting shaft 710. One side of the support cloth 711 is connected to the movable rod 77.

[0036] Please see Figure 1 and Figure 4-5 In this embodiment of the invention, a spiral spring 712 is wound around one end of the limiting shaft 710, and the two ends of the spiral spring 712 are respectively connected to the inner wall of the opening groove on the moving plate 72 and the outer wall of the limiting shaft 710.

[0037] Please see Figure 4-5 In this embodiment of the invention, the clamping anti-drop component 7 further includes a position adjustment mechanism 73 for driving the longitudinal movement of the movable plate 72. The position adjustment mechanism 73 includes a protrusion 735 disposed on one side of the movable plate 72 and an adjustment servo motor 731 installed on one side of the housing base 61. The output shaft of the adjustment servo motor 731 is connected to a lead screw 732. One end of the lead screw 732 is externally screwed to a movable seat 733. A connecting rod 734 is hinged to the side of the movable seat 733 away from the housing base 61. The side of the connecting rod 734 away from the movable seat 733 is hinged to one side of the protrusion 735.

[0038] In the above scheme, after the glass bottle is clamped, the servo motor 731 drives the lead screw 732 to rotate. The lead screw 732 drives the moving seat 733 to move. The moving seat 733 causes the connecting rod 734 to drive the moving plate 72 to move longitudinally on the guide rod 71, so that the moving rod 77 is lower than the bottom of the bottle. Then, the servo motor 74 drives the threaded rod 78 to rotate. The threaded rod 78 drives the nut block 79 to move. The nut block 79 drives the moving sleeve 76 to move laterally on the limiting cylinder 75. The moving sleeve 76 drives the moving rod 77 to move. The moving rod 77 can hold the bottle in place. The cloth 711 is unfolded to cover the bottom of all the bottles, and then the moving plate 72 is moved upward. In this way, the cloth 711 will support the bottom of all the glass bottles to prevent them from falling and breaking. When loading and unloading, the threaded rod 78 drives the nut block 79 to move back, which in turn drives the moving rod 77 to move back. Since the spiral spring 712 has the characteristic of elastic automatic winding, the spiral spring 712 will drive the limit shaft 710 to rotate. The limit shaft 710 will then wind up the cloth 711 so that it does not hinder the normal loading and unloading of the glass bottles.

[0039] Example 4 differs from Example 1 in that:

[0040] Please see Figure 1-2 In this embodiment of the invention, a rotary cylinder 5 for driving the gripping component 4 to flip is installed on the side of one of the limiting plates 3 away from the gripping component 4, and L-shaped clamping blocks 47 are provided on the upper side of the moving blocks 45 on both sides, with the two L-shaped clamping blocks 47 arranged opposite each other.

[0041] In the above scheme, the rotary cylinder 5 drives the clamping component 4 to rotate 180 degrees, so that the L-shaped clamping block 47 faces downward. Under the movement of the palletizing servo motor 44, the two L-shaped clamping blocks 47 can move, and the two L-shaped clamping blocks 47 can clamp the trays of glass bottles placed at intervals, which facilitates the palletizing of glass bottles.

[0042] Working principle: The robotic arm 1 is raised and lowered by an external drive device, so that the gripping component 4 moves to the position of the glass bottle, so that the bottle mouth of each glass bottle is located between the two clamping plates 46. Then, the palletizing servo motor 44 drives the double-threaded screw 43 to rotate. Since the two threads on the double-threaded screw 43 are opposite to each other, the two moving blocks 45 will move in opposite directions, so that the two moving blocks 45 move relative to each other, thus clamping the bottle mouth of the glass bottle.

[0043] Under the operation of the reinforced servo motor 63, the two nut sleeves 64 at the double thread can move, thereby driving the two reinforcing rods 65 to move. Since the two double threads are opposite to each other, the two reinforcing rods 65 can clamp the other two sides of the bottle mouth, ensuring the firmness of the glass bottle clamping and making it less likely to fall off.

[0044] After the glass bottle is clamped, the servo motor 731 drives the lead screw 732 to rotate. The lead screw 732 drives the moving seat 733 to move. The moving seat 733 causes the connecting rod 734 to drive the moving plate 72 to move longitudinally on the guide rod 71, so that the moving rod 77 is lower than the bottom of the bottle. Then, the servo motor 74 drives the threaded rod 78 to rotate. The threaded rod 78 drives the nut block 79 to move. The nut block 79 drives the moving sleeve 76 to move laterally on the limiting sleeve 75. The moving sleeve 76 drives the moving rod 77 to move. The moving rod 77 can hold the support cloth 71. 1. Unfold the cloth to cover the bottom of all the bottles, and then move the moving plate 72 upward. This will support the bottom of all the glass bottles and prevent them from falling and breaking. When loading and unloading, the threaded rod 78 drives the nut block 79 to move back, which in turn drives the moving rod 77 to move back. Since the spiral spring 712 has the characteristic of elastic automatic winding, the spiral spring 712 will drive the limit shaft 710 to rotate. The limit shaft 710 will then wind up the cloth 711 so that it does not hinder the normal loading and unloading of the glass bottles.

[0045] The rotating cylinder 5 drives the gripping component 4 to rotate 180 degrees, so that the L-shaped gripper 47 faces downward. Under the movement of the palletizing servo motor 44, the two L-shaped grippers 47 can move. The two L-shaped grippers 47 can hold the trays of glass bottles placed at intervals, which is convenient for stacking glass bottles.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
