Description

Technical Field

[0001] The invention relates to the technical field of storage board reinforcement placing equipment, in particular to a reinforcement lifting machine and a double-station automatic reinforcement placing machine for storage board processing. Background Art

[0002] The storage boards used in storage shelves need to be spot-welded with several reinforcing ribs inside, which can reduce the thickness of the layer material while bearing the same load.

[0003] The traditional way to place reinforcement ribs into the storage board before spot welding is to place them manually, with workers placing the reinforcement ribs one by one and clamping the two ends into the flange of the storage board, which is very inefficient. Later, our company developed an automatic reinforcement placing machine and designed a rotatable grab and place component. After grabbing the reinforcement rib, it moves to the board, rotates to align the reinforcement rib and clamps it into the flange, effectively improving production efficiency.

[0004] In the structure of the automatic rib placing machine, the reinforcement is supplied by a scissor-type lifting mechanism. The disadvantage is that the distance the rib moves per unit time during the lifting process is different. The higher the rib is sucked, the higher the height is. The rib sucking mechanism is difficult to control. If a worm gear lifting mechanism is used, it will take up too much space, so the number of reinforcements is limited, affecting continuous production.

[0005] In addition, the movement of the grabbing and releasing components in the structure of the automatic rib-releasing machine is achieved by using standard modules. Under high-speed operation, the modules have a short service life, high price, and insufficient load-bearing capacity. Therefore, the existing technology needs to be improved.

[0034] See also Figures 1 to 4 The first embodiment of the present invention provides a double-station automatic rib laying machine for storage boards, comprising:

[0035] The layer plate conveyor 1 has a layer plate transmission structure 11 disposed on its working surface for transmitting the layer plates 5;

[0036] Two reinforcement rib elevators 2 are respectively arranged on the left and right sides of the layer plate conveyor 1, and are used to stack and supply reinforcement ribs;

The reinforcement taking mechanism 4 is slidably set on the first guide rail 31, and is used to alternately grab the reinforcement ribs 6 from the reinforcement rib elevators 2 on both sides and place them into the layer plate. By adopting a double-station reinforcement taking position, it can be ensured that the production time does not stop, which greatly improves the output.

[0038] The design of the reinforcement lifting machine 2 in the double-station automatic reinforcement placing machine is as follows:

[0039] The chassis 21 includes a chassis 21, a bottom frame 22 and a plurality of rib positioning strips 23. Two pairs of sliders 221 are arranged outside the bottom frame 22. Two pairs of vertical guide rails 211 are arranged inside the chassis 21.

Two rib positioning blocks 231 are arranged on the rib positioning strips 23 to limit the placement position of the reinforcing ribs.

[0040] A pair of vertical racks 212 are arranged at the front and back of the chassis 21, and a horizontally rotatable shaft 222 is arranged below the bottom frame 22. Gears 223 are arranged at both ends of the shaft 222, and the gears are meshed and connected with the corresponding racks. A servo motor 224 is also arranged on the bottom frame 22 for driving the shaft 222 to rotate and control the lifting and lowering action of the bottom frame 22.

[0041] Specifically, the servo motor 224 is also equipped with a reducer. The servo motor 224 and the reducer are connected by a coupling to achieve fixation and transmission. The output shaft of the reducer and the gear are connected by a key connection to ensure that the rack and pinion structure can transmit motion smoothly and accurately.

[0042] In order to make the placement of the reinforcement more accurate, there are corresponding block settings:

[0043] A first horizontal guide rail is provided on the outer side of the chassis 21, and a plurality of fixed blocks 213 are provided on the first horizontal guide rail, each of which corresponds to a rib positioning strip 23. A movable beam is provided on the inner side of the chassis 21, and the front and rear ends of the movable beam are slidably connected to the inner wall of the chassis 21, and can be horizontally close to or away from the first horizontal guide rail. A second horizontal guide rail is provided on the side of the movable beam, and a plurality of movable blocks 214 corresponding to the fixed blocks 213 are provided on the second horizontal guide rail, and the two cooperate to realize the lateral positioning of reinforcing ribs of different sizes;

[0045] Specifically, before the rib placing machine is started, a certain number of reinforcing ribs are placed manually or by a robot on each rib positioning block 231 to a set height, and then the moving block 214 is moved against one end of the reinforcing rib and a 2 mm gap is retained.

[0046] The design of the reinforcement taking mechanism 4 in the double-station automatic reinforcement placing machine is as follows:

[0047] The tendon removal mechanism 4 includes a translation component, a lifting component and a tendon suction component;

[0048] The translation assembly includes a moving plate 41 slidably arranged on the first guide rail 31, a translation motor 411 is arranged on the moving plate 41, a driving end of the translation motor 411 is downwardly arranged and provided with a first gear 412, a first rack 32 parallel to the first guide rail 31 is arranged in the bracket 3, the first gear 412 is meshed and connected with the first rack 32, and the moving plate 41 moves back and forth between the stiffener elevator 2 and the layer plate conveyors 1 on both sides under the drive of the translation motor 411;

[0049] The lifting assembly includes a connecting frame 42 that is arranged on the movable plate 41, a lifting motor 421 is arranged on the outside of the connecting frame 42, the driving end of the lifting motor 421 passes through the connecting frame 42 horizontally and is provided with a second gear 422, a lifting rod 43 is slidingly arranged in the connecting frame 42, a second rack 431 in the vertical direction is arranged on one side of the lifting rod 43, the second gear 422 and the second rack 431 are meshed and connected, and the rib suction assembly is arranged at the bottom end of the lifting rod 43, and the plate is taken or put down under the action of the lifting motor 421.

[0050] Specifically, the lifting rod 43 is made of a 100*100 square aluminum profile, wherein three outer walls are provided with rod outer guide rails, and a corresponding frame inner slider 221 is provided in the connecting frame 42, so that the lifting rod 43 can be stably lifted and lowered in the connecting frame 42.

[0051] Specifically, the rib removal mechanism 4 adopts a load control method when removing the ribs, compresses the ribs and reaches a certain load, so as to ensure that the claws and the upper plane of the reinforcing ribs are in close contact, and ensure that the rib removal position is accurate.

[0052] The design of the rib suction component in the double-station automatic rib placing machine is as follows:

[0053] The rib suction assembly includes an L-shaped plate 44 arranged at the bottom end of the lifting rod 43, a plurality of rotatable third gears 441 are arranged at the bottom of the L-shaped plate 44, a rotating cylinder 442 is arranged at one end of the L-shaped plate 44, a driving end of the rotating cylinder 442 horizontally passes through the L-shaped plate 44 and is provided with a third rack 443, the third gear 441 and the third rack 443 are meshingly connected, a suction cup connecting plate 45 is arranged under each third gear 441, a pair of vacuum suction cups 46 and a pair of U-shaped claws 47 are arranged under the suction cup connecting plate 45, under the action of the rotating cylinder 442, the reinforcement ribs adsorbed by the vacuum suction cup 46 can be rotated a certain angle and then placed into the layer.

[0054] Specifically, the adsorption of the reinforcing rib is achieved by the vacuum suction cup 46 and the vacuum generator connected thereto.

[0055] Specifically, the number and position of the third gears 441 and the rib positioning strips 23 can be adjusted according to the number and position of the reinforcing ribs required in the layer board.

[0056] In order to enable the rib removal mechanism 4 to accurately and quickly grab the reinforcement ribs from the reinforcement rib elevators 2 on both sides, an induction grating is also provided:

[0057] The induction grating can be set on the middle layer conveyor 1, or on the reinforcing rib elevators 2 on both sides, to sense whether there are ribs at the grabbing position of the reinforcing rib elevator 2;

[0058] When the reinforcing rib on the left side is removed, the corresponding sensing grating cannot sense the existence of the reinforcing rib, and the servo motor 224 on the left side starts to lift the bottom frame 22. When the sensing grating senses the reinforcing rib, the servo motor 224 stops working.

[0059] Regarding the rotation and placement of the reinforcing ribs: when the ribs are sucked, the reinforcing ribs are parallel to each other. After the reinforcing ribs are moved above the layer plate, the rotating cylinder 442 is activated to rotate the reinforcing ribs by an angle, and then they move down to the inside of the layer plate. The rotating cylinder 442 is reset to turn the reinforcing ribs back to a parallel state. At this time, the vacuum suction cup 46 is released and the rib removal mechanism 4 returns.

[0060] Specifically, the layer plate transmission structure 11 has a corresponding layer plate positioning structure to ensure the stability of the layer plate during the placement of the reinforcement ribs.

[0061] The beneficial effects of the reinforcement rib elevator and double-station automatic rib placing machine for storage board processing of the present invention are:

[0062] 1. In the rib lifter, the bottom frame slides in the chassis through vertical guide rails, and a gear rack combination transmission is used to control the lifting, making the structure stable and reliable. The lifting height is fixed each time, which is convenient for taking the ribs;

[0063] 2. The rib-taking mechanism moves back and forth between the rib elevator and the layer conveyor through the bracket. The bracket provides good load-bearing capacity, can adapt to high-speed operation, and effectively grab and place the ribs;

[0064] 3. The horizontal movement, vertical movement and rotation of the rib suction assembly are all driven by a gear rack structure, which has a simple and stable structure and can smoothly and accurately grab and move the reinforcement ribs;

[0065] 4. A double-station reinforcement rib elevator is used, and two elevators are used back and forth to ensure that production does not stop, thereby increasing output.
