Description

Technical Field

[0001] This utility model specifically relates to a feeding and stacking device for the inner tube powder cake of combined fireworks. Background Technology

[0002] In the fireworks production process, after the fireworks tubes are processed, they need to be unloaded and stacked for subsequent packaging and transportation. Currently, most fireworks tube unloading and stacking devices on the market use electric drives to achieve the displacement and clamping of various components. However, electric drives pose a risk of electric leakage during use, especially in places with extremely high safety requirements such as fireworks production workshops, where electric leakage accidents could lead to serious safety hazards. Furthermore, existing clamping mechanisms are mostly rigid clamping structures and lack precise gripping position control mechanisms—the first cylinder's downward movement is often driven by a fixed stroke, which can easily lead to gripping deviation or collision due to finished product positional deviations. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a feeding and stacking device for the inner tube powder cake of combined fireworks. A feeding and stacking device for the inner tube powder cake of combined fireworks includes a frame. Two or more first guide shafts are arranged laterally on the frame at intervals. A first movable seat is movably sleeved on the first guide shaft via a linear bearing. The first movable seat is respectively provided with a clamping mechanism and a first cylinder for driving the clamping mechanism to move up and down. The frame is provided with a driving component that can drive the first movable seat to move axially along the first guide shaft. The clamping mechanism includes a second movable seat, a connecting seat, a first proximity switch, a double-headed cylinder, and two clamping plates. The connecting seat is disposed on the drive shaft of the first cylinder. The second movable seat is movably disposed on the connecting seat. The first proximity switch is disposed on the connecting seat and can sense and cooperate with the upwardly moving second movable seat. The double-headed cylinder is disposed on the second movable seat. The two clamping plates are symmetrically disposed on the two drive shafts on both sides of the double-headed cylinder.

[0004] In one embodiment, a plurality of second guide shafts are spaced apart on the second movable seat. The second guide shafts are movably connected to the connecting seat via linear bearings. A first limiting block is provided on the second guide shaft above the connecting seat. The first limiting block abuts against the upper side of the connecting seat. The second guide shaft can be sensed and cooperated with a first proximity switch.

[0005] In one embodiment, a connecting plate is provided on one side of the first movable seat, and an opening is provided through the connecting plate. A blocking member is movably arranged on the connecting plate via a slide rail slider. A fourth cylinder is provided on the connecting plate to drive the blocking member to move. A vertical plate is connected to the connecting seat within the opening. A baffle is provided at the upper end of the vertical plate. A hydraulic buffer that can abut against the blocking member is provided on the baffle. A first sensor and a second sensor are provided at intervals along the extension and retraction direction of the first cylinder. The first sensor is used to detect when the first cylinder resets and rises to a safe height after sensing material picking. The second sensor is used to detect the contact position between the baffle and the blocking member when sensing the extension of the first cylinder.

[0006] In one embodiment, the driving component includes a second cylinder and a third cylinder respectively disposed on the frame. The drive shaft of the second cylinder is connected to the first movable seat to drive the first movable seat to move axially along the first guide shaft. A fixed shaft is connected to the drive shaft of the third cylinder. The fixed shaft passes through the first movable seat through a linear bearing.

[0008] In one embodiment, the frame is provided with a limiting rod that can abut against the first movable seat; when the limiting rod abuts against the first movable seat, the drive shafts of the second cylinder and the third cylinder are both in the initial retracted working state.

[0009] In summary, the advantages of this utility model over the prior art are: This invention completely avoids the risk of electric leakage associated with electric drives through a pneumatic drive design, meeting the safety requirements of fireworks workshops. Furthermore, the floating chuck, through a "touch-up-sensing" linkage mechanism, can adaptively stack fireworks tubes of different heights, preventing damage caused by rigidity. The second and third cylinders form a "drive-limit" cooperative structure, combined with precise positioning by multiple magnetic switches, enabling rapid switching between two palletizing stations. Compared to single-station devices, this improves palletizing efficiency and meets the needs of mass production. Attached Figure Description

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 The present invention preferably provides a feeding and stacking device for the inner tube powder cake of combined fireworks, including a frame 1. Two or more first guide shafts 2 are arranged laterally at intervals on the frame 1. A first movable seat 3 is movably sleeved on the first guide shaft 2 via a linear bearing. The first movable seat 3 is respectively provided with a clamping mechanism 4 and a first cylinder 5 for driving the clamping mechanism 4 to move up and down. The frame 1 is provided with a driving member 6 capable of driving the first movable seat 3 to move axially along the first guide shaft 2. The structure 4 includes a second movable seat 41, a connecting seat 42, a first proximity switch 43, a double-headed cylinder 44, and two clamping plates 45; wherein, the connecting seat 42 is disposed on the drive shaft of the first cylinder 5, the second movable seat 41 is movably disposed on the connecting seat 42, the first proximity switch 43 is disposed on the connecting seat 42 and can sense and cooperate with the upwardly moving second movable seat 41, the double-headed cylinder 44 is disposed on the second movable seat 41, and the two clamping plates 45 are symmetrically disposed on the two drive shafts of the double-headed cylinder 44 respectively.

[0012] Specifically, the combination of the driving component, the first cylinder, and the clamping mechanism enables the unloading and conveying of finished firework tubes. During stacking, the first cylinder drive shaft moves downward, bringing the firework tubes closer to the stacking surface. When the bottom of the firework tube touches the stacking surface, the firework tube generates a reaction force that pushes the second moving seat upward relative to the connecting seat. When the second moving seat moves to the detection range of the first proximity switch, the first proximity switch sends a "placed in place" signal, controlling the double-headed cylinder drive shaft to extend, the two clamping plates to loosen, and the firework tube to fall smoothly to the stacking position. At the same time, the first cylinder resets and moves upward, realizing the unloading, stacking, and stacking of firework tubes. Furthermore, the floating clamping structure uses a cylinder-driven method to replace the electric drive method, effectively reducing the risk of leakage from electrical components.

[0013] Furthermore, the second movable seat 41 is provided with a plurality of second guide shafts 46 at intervals. The second guide shafts 46 are movably connected to the connecting seat 42 via linear bearings. A first limiting block 47 is provided on the second guide shaft 46 above the connecting seat 42, and the first limiting block 47 abuts against the upper side of the connecting seat 42. The second guide shaft 46 can be inductively engaged with the first proximity switch 43. Specifically, the engagement of the second guide shaft with the first limiting block enables the second movable seat to move vertically relative to the connecting seat, and the inductive engagement of the second guide shaft with the first proximity switch facilitates the triggering control of the first proximity switch.

[0014] Furthermore, a connecting plate 31 is provided on one side of the first movable seat 3. An opening 32 is provided through the connecting plate 31. A blocking member 33 is movably arranged on the connecting plate 31 via a slide rail slider. A fourth cylinder 34 is provided on the connecting plate 31 to drive the blocking member 33 to move. A vertical plate 35 is connected to the connecting seat 42 within the opening 32. A baffle 36 is provided at the upper end of the vertical plate 35. A hydraulic buffer that can abut against the blocking member 33 is provided on the baffle 36. A first sensor (not shown in the figure) and a second sensor (not shown in the figure) are arranged at intervals along the extension and retraction direction of the first cylinder 5. The first sensor (not shown in the figure) is used to detect when the first cylinder 5 resets and rises to a safe height after sensing material picking. The second sensor (not shown in the figure) is used to detect the contact position between the baffle and the blocking member when sensing the extension of the first cylinder 5.

[0015] Specifically, when the clamping mechanism is driven to be directly above the finished product clamping station, the double-headed cylinder drive shaft extends, and the two clamping plates open. The fourth cylinder drives the blocking component to move directly below the vertical plate. When the vertical plate moves the baffle down to contact the blocking component, the second sensor on the first cylinder sends an electrical signal, and the controller simultaneously executes two key actions: ① Sending a "gripping position in place" signal, the control system immediately controls the first cylinder to stop moving down; ② Sending a "clamping start" signal, the control system directly controls the double-headed cylinder drive shaft to retract, and the two clamping plates close to clamp the firework tube. Throughout the gripping process, the first proximity switch remains in a non-triggered state and does not participate in any signal transmission or action control. After the finished product is gripped, the first cylinder drive shaft resets upward, driving the firework tube to a preset height; simultaneously, the fourth cylinder drives the blocking component to reset. Thus, through the cooperation of the blocking component and the fourth cylinder, the clamping mechanism can grip the finished product at the corresponding clamping height.

[0016] Further, the driving component 6 includes a second cylinder 61 and a third cylinder 62 respectively mounted on the frame 1. The drive shaft of the second cylinder 61 is connected to the first movable seat 3 to drive the first movable seat 3 to move axially along the first guide shaft 2. A fixed shaft 63 is connected to the drive shaft of the third cylinder 62. The fixed shaft 63 passes through the first movable seat 3 via a linear bearing. A second limiting block 64 that can abut against the first movable seat 3 is provided on the fixed shaft 63. Further, a first magnetic switch 65, a second magnetic switch 66, and a third magnetic switch 67 that can cooperate with the magnetic ring on its piston are respectively provided on the second cylinder 61 along its driving direction. The first magnetic switch 65 detects the finished product gripping position, the second magnetic switch 66 detects the first palletizing position, and the third magnetic switch 67 detects the second palletizing position.

[0017] Specifically, when the finished product needs to be transported from the clamping station to the first palletizing station, after the finished product is grabbed and lifted to a safe height, the second cylinder drive shaft is extended while the third cylinder remains retracted. The first moving seat is driven by the second cylinder to move to a connection state that abuts against the second limit block. At this time, the piston of the second cylinder triggers the second magnetic switch, and the second cylinder is stopped by the third cylinder (the third cylinder has a larger cylinder diameter than the second cylinder, and the second cylinder is still in the air supply state in this state). The clamping station is positioned at the first palletizing station. When it is necessary to switch from the first palletizing station to the second palletizing station, that is, after the first palletizing station is completed, the first cylinder first resets upward, the second cylinder and the third cylinder are simultaneously in the retracted state, the clamping mechanism resets and moves to the top of the clamping station, the first cylinder drives the clamping mechanism to move down to grab the finished product and then moves up to reset, and then controls the second cylinder drive shaft and the third cylinder drive shaft to extend simultaneously, the first moving seat is driven by the second cylinder to move to the connection state of abutting against the second limit block, and at this time when the second cylinder piston triggers the third magnetic switch, the device switches to the second palletizing station; When switching from the first or second palletizing station to the clamping station, the third cylinder drive shaft is retracted, and then the second cylinder drive shaft is retracted. Finally, both cylinders are in the retracted state, and the device is reset to the finished product clamping station, entering the next cycle of "second sensor detection for material gripping - first proximity switch for material release".

[0018] Furthermore, the frame 1 is provided with a limiting rod 91 that can abut against the first movable seat 3; when the limiting rod 91 abuts against the first movable seat 3, the drive shafts of the second cylinder 61 and the third cylinder 62 are both in the initial retracted working state, and the material gripping position can be adjusted by adjusting the limiting rod 91.

[0019] In summary, the process of this application is as follows: Initial state When the drive shafts of the second and third cylinders retract simultaneously, the device is in the finished product clamping position: the first moving seat abuts against the limit rod and stops at the end of the finished firework tube conveyor belt; the double-headed cylinder drive shaft extends, and the two clamping plates are in an open state; the fourth cylinder drives the blocking component to move to directly below the vertical plate, and the second sensor for detecting the material gripping position of the first cylinder enters the standby state; the first cylinder drive shaft extends, and the initial height of the clamping mechanism is adapted to the firework tube output from the conveyor belt. Finished product grasping: solely dependent on the second proximity switch After receiving the "pile-ready signal," the control system issues a command to lower the first cylinder: the first cylinder drives the connecting seat, vertical plate, and clamping mechanism to move downwards as a whole. When the vertical plate moves the baffle down to contact the blocking component, the second sensor on the first cylinder sends an electrical signal, simultaneously executing two key actions—① sending a "grip position in place" signal, the control system immediately controls the first cylinder to stop moving downwards; ② sending a "clamping start" signal, the control system directly controls the double-headed cylinder drive shaft to retract, and the two clamping plates close to clamp the firework tube. Throughout the entire gripping process, the first proximity switch remains in a non-triggered state and does not participate in any signal transmission or action control.

[0020] Stacked placement: uniquely triggers the first proximity switch After the finished product is picked up, the first cylinder drives the shaft to reset upwards, raising the fireworks tube to the preset height; simultaneously, the fourth cylinder drives the blocking component to reset. After the device moves to the target palletizing station according to the station switching logic: The first cylinder drives the shaft downwards, bringing the firework tube closer to the stacking surface. When the bottom of the firework tube touches the stacking surface, the tube generates a reaction force that pushes the second moving seat upwards relative to the connecting seat, simultaneously moving the second guide shaft upwards. When the second guide shaft moves into the detection range of the first proximity switch, the first proximity switch becomes the sole trigger element, sending a "placement in place" signal. The control system then controls the double-headed cylinder drive shaft to extend, the two clamps to loosen, and the firework tube smoothly falls to the stacking position. During this stage, the stacking placement is controlled solely by the first proximity switch.

[0021] Dual-station switching and cyclic reset Clamping station → First palletizing station: After the finished product is gripped, the control system controls the second cylinder drive shaft to extend, while the third cylinder remains retracted; when the second cylinder stops due to the obstruction of the third cylinder, the cylinder piston triggers the second magnetic switch (the third cylinder has a larger diameter than the second cylinder, and the second cylinder is still in the ventilated state in this state), and the device switches to the first palletizing station, and then completes the stacking and placement according to the logic of "only triggering the first proximity switch".

[0022] First palletizing station → Second palletizing station: After the first station is completed, the first cylinder is reset; the control system controls the third cylinder drive shaft to extend, and the second cylinder drive shaft to extend. When the second cylinder is stopped by the third cylinder, the cylinder piston triggers the third magnetic switch, and the device switches to the second palletizing station, repeating the "unique trigger first proximity switch" stacking action.

[0023] Palletizing station → Clamping station reset: After the second station is completed, the control system controls the second cylinder drive shaft and the third cylinder drive shaft to retract simultaneously. Finally, both cylinders are in the retracted state. The piston of the second cylinder triggers the first magnetic switch, and the device is reset to the clamping station, entering the next cycle of "second sensor detection gripping - first proximity switch releasing".
