Description

Technical Field

[0001] The utility model relates to the technical field of capsule machines, and more specifically to a rod blanking device for a capsule machine. Background Art

[0002] A capsule machine is a special device for producing hollow hard capsules. During the production of capsules, multiple needle dies are fixed on a rectangular strip to form a needle die group. Then, it is necessary to move the needle die group to perform technological processes such as gluing, conveying, descending, demolding, cutting, nesting, and oiling. In the above technological processes, it is necessary to change the longitudinal movement of the needle die group (which can also be called the rod strip group) into lateral movement, and change the state of the rod strip group from a side-mounted state (i.e., the needle die is horizontally placed) to a lying state (i.e., the needle die is vertically placed). This process is called rod dropping; after rod dropping, the rod strip group will be pushed to the next working station for subsequent processing.

[0003] In the prior art, the rod strip group is driven by gravity during rod dropping, and its dropping position cannot be controlled, and it is very easy for two rod strip groups that drop successively to be stuck together. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rod blanking device for a capsule machine, so as to make the dropping position of the rod strip group controllable and avoid two rod strip groups that drop successively from being stuck together.

The slide rail frame is hinged to the base. A chute is provided on the slide rail frame for accommodating the strip of the rod strip group and enabling the strip to slide in the chute. The flipping drive mechanism is connected to the slide rail frame, and the flipping drive mechanism is used to make the slide rail frame rotate between a first position and a second position relative to the base, so that the rod strip group located in the chute drops at a fixed position.

[0007] Further, at least one first hinge part is provided on the base, and the first hinge shaft passes through the first hinge part and the hinge bracket, so that the first hinge part and the hinge bracket are hinged.

[0008] Further, the flipping driving mechanism includes a first driving device, a driving rod, and at least one hinged arm. The number of the hinged arms is the same as and corresponds one by one to the number of the slide rail frames.

[0016] For the bar dropping device of the capsule machine of the present invention, the slide rail frame is driven to rotate by the flipping driving mechanism so that the bar group on the slide rail frame drops.

[0023] The preferred embodiments of the present utility model will be given and described in detail below in conjunction with the accompanying drawings.

[0024] As shown in Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a rod dropping device for a capsule machine, which includes a base 100, at least one slide rail frame 200, and a flipping drive mechanism 300. The slide rail frame 200 is hinged to the base 100. A chute 210 extending in the Y direction is provided on the slide rail frame 200. The rod group 400 includes a slat 410 and a plurality of needle dies 420 fixed on the slat 410. The plurality of needle dies 420 can be evenly arranged along the length direction of the slat 410. The chute 210 is used to accommodate the slat 410 and enable the slat 410 to slide therein, so that the rod group 400 can move in the Y direction in the chute 210. The flipping drive mechanism 300 is connected to the slide rail frame 200 and is used to make the slide rail frame 200 rotate relative to the base 100 around the Y direction between a first position and a second position; when the slide rail frame 200 is in the first position, the slat 410 of the rod group 400 on the slide rail frame 200 extends in the Y direction (i.e., its length direction is parallel to the Y direction), and the rod group 400 is in a side-mounted state, that is, the long plane (i.e., the top surface and the bottom surface) of the slat 410 of the rod group 400 is perpendicular to the horizontal plane (i.e., the XY plane), and the short plane (i.e., the side surface) is parallel to the horizontal plane, and the needle dies 420 are parallel to the horizontal plane. At this time, the plurality of needle dies 420 of the rod group 400 all extend outside the slide rail frame 200; when the slide rail frame 200 is in the second position, the rod group 400 on the slide rail frame 200 is flipped from the side-mounted state to a lying state (i.e., the long plane of the slat 410 is parallel to the horizontal plane and the needle dies 420 are perpendicular to the horizontal plane). Under the action of gravity, the rod group 400 will fall onto a receiving device (not shown in the figure), thereby realizing rod dropping. Since the rod dropping (i.e., material dropping) of the rod group 400 is realized by the rod group 400 following the rotation of the slide rail frame 200, and the trajectory of the slide rail frame 200 is determined, the dropping position of the rod group 400 is also determined, that is, the dropping position of the rod group 400 is controllable. After the previous rod group 400 drops, the receiving device can move it away from the dropping position, so as to avoid the rod group 400 dropped later from being stacked with the rod group 400 dropped earlier.

[0025] In some embodiments, at least one hinge bracket 110 may be fixed on the base 100. The slide rail frame 200 is hinged to the hinge bracket 110 through a first hinge shaft 120. The slide rail frame 200 can rotate relative to the hinge bracket 110 around the first hinge shaft 120; the first hinge shaft 120 can extend in the Y direction, so that the slide rail frame 200 can rotate around the Y direction.

[0026] At least one first hinge portion 220 may be provided on the base 100. Through holes for the first hinge shaft 120 to pass through may be provided on both the first hinge portion 220 and the hinge bracket 110. Thus, the first hinge shaft 120 can pass through the first hinge portion 220 and the hinge bracket 110 to hinge the slide rail frame 200 and the hinge bracket 110.

[0027] In an exemplary embodiment, there are two articulated brackets 110 and also two first articulated parts 220. The two articulated brackets 110 are arranged at intervals in the X direction, and the two first articulated parts 220 are arranged at intervals in the X direction. Moreover, the two articulated brackets 110 are located between the two first articulated parts 220. The first articulated shaft 120 sequentially passes through one of the first articulated parts 220, the two articulated brackets 110, and the other first articulated part 220 in the X direction, so that the slide rail frame 200 is articulated with the articulated brackets 110.

[0028] As Figure 3 , Figure 4 and Figure 5 shown, in some embodiments, the flipping drive mechanism 300 may include a first drive device 310, a drive rod 320, and at least one articulated arm 330. The number of the articulated arms 330 is the same as that of the slide rail frames 200 and they are in one-to-one correspondence. The first drive device 310 is connected to one end of the drive rod 320. The other end of the drive rod 320 is articulated with one end of the articulated arm 330. The other end of the articulated arm 330 is articulated with the corresponding slide rail frame 200. The drive rod 320 extends in the Z direction. The first drive device 310 is used to lift and lower the drive rod 320 in the Z direction. The lifting and lowering of the drive rod 320 causes the articulated arm 330 to move together. The movement of the articulated arm 330 causes the corresponding slide rail frame 200 to rotate around the first articulated shaft 120 between a first position and a second position.

[0029] In some embodiments, the articulated arm 330 may be articulated with the corresponding slide rail frame 200 through a second articulated shaft 331. Specifically, at least one second articulated part 230 may be provided on the slide rail frame 200. Through holes for the second articulated shaft 331 to pass through may be provided on both the articulated arm 330 and the second articulated part 230. The second articulated shaft 331 may pass through the articulated arm 330 and the second articulated part 230, so that the articulated arm 330 is articulated with the second articulated part 230. Through holes for the first articulated shaft 120 to pass through may also be provided on the second articulated part 230, so that the first articulated shaft 120 passes through the second articulated part 230, thereby making the connection between the first articulated shaft 120 and the slide rail frame 200 more stable. Exemplarily, there may be two second articulated parts 230. The two second articulated parts 230 are arranged at intervals in the Y direction. The end of the articulated arm 330 that is articulated with the slide rail frame 200 is located between the two second articulated parts 230. The second articulated shaft 331 sequentially passes through one of the second articulated parts 230, the articulated arm 330, and the other second articulated part 230, so that the second articulated part 230 and the articulated arm 330 are connected.

[0030] In some embodiments, the first driving device 310 may be a cylinder. The cylinder shaft 311 of the cylinder may be arranged along the Z direction. The cylinder shaft 311 may be connected to the driving rod 320 through a connecting shaft 340. When the cylinder shaft 311 rises along the Z direction, the driving rod 320 also rises along the Z direction, and the slide rail frame 200 will rotate towards the second position; conversely, when the cylinder shaft 311 descends along the Z direction, the driving rod 320 also descends along the Z direction, and the slide rail frame 200 will rotate towards the first position. Threaded holes may be provided at both ends of the connecting shaft 340 so that both ends of the connecting shaft 340 are threadedly connected to the cylinder shaft 311 and the driving rod 320 respectively.

[0031] In some embodiments, the first driving device 310 may also be a motor. The output shaft of the motor is connected to the driving rod 320 through a transmission mechanism (such as a worm and worm gear, a ball screw, etc.) to enable the driving rod 320 to move up and down along the Z direction.

[0032] In some embodiments, the first driving device 310 may be fixed on a fixed seat 350, and the fixed seat 350 is fixed on the base 100, so that the first driving device 310 can be installed on the base 100.

[0033] In some embodiments, the base 100 may have a protrusion 130. The protrusion 130 defines a groove 131. A part of the driving rod 320 is located in the groove 131, and the articulated arm 330 is located below the protrusion 130. In this way, the groove 131 can serve as the movement space for the driving rod 320 and the articulated arm 330, enabling the driving rod 320 and the articulated arm 330 to move therein without interfering with the base 100.

[0034] In an exemplary embodiment, there are two slide rail frames 200 and two articulated arms 330. One end of each of the two articulated arms 330 is articulated with one end of the driving rod 320. The two slide rail frames 200 are respectively located on both sides of the base 100 in the X direction and are respectively articulated with both sides of the articulated bracket 110 in the X direction. The other ends of the two articulated arms 330 are respectively articulated with the two slide rail frames 200. In this way, as Figure 5As shown, when the drive rod 320 moves upward, it will cause both hinge arms 330 to move upward. At the same time, the left hinge arm 330 will rotate counterclockwise, and the left slide rail frame 200 will also rotate counterclockwise, so that the slide rail frame 200 can rotate towards the second position. The right hinge arm 330 will rotate clockwise, and the right slide rail frame 200 will also rotate clockwise, so that the slide rail frame 200 can rotate towards the second position. Conversely, when the drive rod 320 moves downward, it will cause both hinge arms 330 to move downward. At the same time, the left hinge arm 330 will rotate clockwise, and the left slide rail frame 200 will also rotate clockwise, so that the slide rail frame 200 can rotate towards the first position. The right hinge arm 330 will rotate counterclockwise, and the right slide rail frame 200 will also rotate counterclockwise, so that the slide rail frame 200 can rotate towards the first position. Thus, the rod dropping of the two bar groups 400 can be realized simultaneously, improving the production efficiency.

[0035] The first drive device 310 can be connected to the control device to realize the lifting of the drive rod 320 through the control device, thereby realizing the automatic control of the blanking.

[0036] In some embodiments, the rod dropping device may further include a pressing component 500, which is fixed on the base 100 and is used to apply a first pressure to the bar group 400 when needed to prevent the bar group 400 from falling when moving in the chute 210. At the same time, it can also apply a second pressure to the bar group 400 when needed to stop the bar group 400 from continuing to move in the Y direction and realize braking. For example, when the bar group 400 moves in the Y direction by an external force and before the preset dropping position, the pressing component 500 can apply a relatively small first pressure to the bar group 400, so that the bar group 400 can continue to move in the Y direction without falling in the X direction; when the bar group 400 moves in the Y direction to the preset dropping position, the external force can be withdrawn, and at the same time, the pressing component 500 is made to apply a relatively large second pressure to the bar group 400 to brake the bar group 400 and prevent it from continuing to move in the Y direction under the action of inertia.

[0037] Such as Figure 6As shown, the top pressing assembly 500 may include a base 510, a column 520, a second driving device 530, a bracket 540, and a pressing block 550. The base 510 may be fixed to the base 100 by screws. The column 520 is fixed to the base 510. The second driving device 530 is fixed to the column 520. The bracket 540 is slidably connected to the column 520. The pressing block 550 is fixed to the bracket 540. The second driving device 530 is connected to the bracket 540 to drive the bracket 540 and the pressing block 550 to slide relative to the column 520 along the Z direction to approach or move away from the bar group 400. When the pressing block 550 gradually approaches and contacts the slats 410 of the bar group 400, the pressing block 550 can apply pressure to the slats 410 to press the slats 410 tightly, thereby preventing the bar group 400 from falling; when the pressure is large enough, the bar group 400 will be stopped from moving along the Y direction.

[0038] In some embodiments, there may be two pressing blocks 550, which are respectively located on both sides of the bracket 540 in the X direction, so as to apply pressure to the slats 410 of the two bar groups 400 in the chutes 210 on both sides in the X direction respectively.

[0039] In some embodiments, the top pressing assembly 500 may include a connecting rod 560. One end of the connecting rod 560 is connected to the second driving device 530, and the other end is connected to the bracket 540 to achieve the transmission of the driving force through the connecting rod 560. In an exemplary embodiment, the connecting rod 560 may be hinged to the bracket 540. For example, a shaft 541 may be fixed on the bracket 540, and a shaft hole is provided on the connecting rod 560. The shaft 541 passes through the shaft hole, and the connecting rod 560 can rotate around the shaft 541.

[0040] The second driving device 530 may be a cylinder, a motor, or any other suitable driving device. When it is a cylinder, the cylinder shaft may be connected to the connecting rod 560, and the connecting rod moves along the Z direction through the telescopic movement of the cylinder shaft, so that the bracket 540 and the pressing block 550 also move along the Z direction. When it is a motor, it is connected to the bracket 540 through transmission mechanisms such as a gear rack and a ball screw, so as to convert the rotation of the motor into the linear movement of the bracket 340.

[0041] In some embodiments, a groove may be provided on the bracket 540, and a protrusion (or the column 520 itself serves as a protrusion) is provided on the column 520. The protrusion can be accommodated in the groove and can slide in the groove, so as to achieve the sliding connection between the bracket 540 and the column 520 and play a guiding role during movement.

[0042] The column 520 can be fixed to the base 510 by screws to conveniently adjust the height of the column 520.

[0043] The second driving device 530 may be connected to a control device to automatically control the lifting of the pressing block 550 through the control device, so as to control the pressing and loosening of the bar group 400.

[0044] A brief introduction to the working process of the rod blanking device of the present utility model is as follows:

[0045] The rod group 400 is pushed into the chute 210 by a pushing device (not shown in the figure) and moves along the Y direction. The control device controls the second driving device 530 to start, so that the pressing block 550 moves downward and presses the slats 410 of the rod group 400 to apply a first pressure to the rod group 400. When the rod group 400 moves along the Y direction to a specified position (i.e., the preset dropping position), the pushing device stops pushing the rod group 400. Then, the control device makes the pressing block 550 continue to press down through the second driving device 530 and applies a second pressure to the rod group 400 to make the rod group 400 stop moving along the Y direction. Then, the control device controls the second driving device 530 to rotate in the reverse direction to make the pressing block 550 leave the slats 410 of the rod group 400. Then, the control device controls the first driving device 310 to operate, so that the slide rail frame 200 rotates from the first position to the second position to achieve blanking. After the blanking is completed, the control device controls the first driving device 310 to rotate in the reverse direction to make the slide rail frame 200 rotate from the second position to the first position. Then, the above process can be repeated to repeatedly achieve the blanking of the rod group 400.

[0046] For the rod blanking device of the capsule machine in the embodiment of the present utility model, the slide rail frame 200 is driven to rotate by the flipping drive mechanism 300, so that the rod group 400 on the slide rail frame 200 drops. Since the movement track of the slide rail frame 200 is determined, the dropping position of the rod group 400 is controllable.

[0047] The above is only the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Various changes can be made to the above embodiments of the present utility model. That is, all simple, equivalent changes and modifications made according to the claims and the content of the specification of the present utility model application fall within the scope of the claims of the present utility model patent.
