Description

Technical Field

[0001] The invention belongs to the technical field of mechanical automation, and in particular to a multifunctional box unpacking and stacking mechanism and method. Background Art

[0002] For workshop production and assembly, the most ideal state is to lateralize the parts line, which not only saves manual sorting work, but also eliminates the secondary transportation link. However, no matter which production method is used, the stacked boxes must be disassembled and used when the parts are taken. When the parts are used up, the empty boxes containing the parts also need to be stacked and returned. However, this method increases the labor intensity during the manual unpacking and stacking process because workers need to bend over and stretch their hands frequently, which may also lead to irregular movements and increase the risk of accidental injuries. At the same time, since it is impossible to accurately control the speed and position of the return box manually, it often takes extra time to adjust, as follows:

[0003] ① The incoming parts are stacked in multiple layers, and they need to be unpacked for use, which involves heavy-duty operations;

[0004] ② The empty box is returned once every 6 beats. If the frequency of returning boxes is high, 144 boxes need to be returned every day, which results in a waste of action;

[0005] ③ The parts are large and the parts boxes are heavy, each box weighing 6 kg. Each time the parts are returned to the box, the worker has to bend over 90 degrees, which can easily cause occupational diseases. The OSHMS rating is Bb, and long-term operation can easily lead to occupational disease hazards.

[0006] ④ The return box space below is small and the parts box is heavy, so it is impossible to smoothly return multiple empty boxes together, resulting in overflow of the parts box.

[0007] Therefore, based on the above problems, it is urgent to develop a mechanism that can automatically unpack and stack boxes. In order to eliminate the heavy-duty work and waste of motion in manual operation, it is necessary to develop an automatic stacking mechanism to solve the hidden dangers of occupational diseases and eliminate the phenomenon of frequent returns and overflow caused by insufficient storage.

[0107] Embodiment 2:

[0108] A multifunctional unpacking and stacking method, using a multifunctional unpacking and stacking mechanism, comprises the following steps:

[0109] S1: The boxes are put into storage area 1 and moved to unpacking and separation area 2;

[0110] The operator places the full box of parts in the storage area 1, and the first full box in-position photoelectric indicator 114 detects the box position. The full box push cylinder 107 drives the push guide rail 109 to push the box to the second full box in-position photoelectric indicator 115. After the box is detected, the full box secondary push cylinder 106 drives the secondary push guide rail 108 to push the box to the full box supply photoelectric indicator 221, then resets, and drives the secondary push guide rail 108 again to push the box to the full box in-position photoelectric indicator 222.

[0111] S2: The box body moves from the unpacking and separation area 2 to the empty storage area 4;

[0112] The unpacking lifting tray 202 is at the bottom, the unpacking lifting tray in-position switch 223 is triggered, the full box in-position photoelectric 222 detects that the box is on the unpacking lifting tray 202, the unpacking lifting cylinder 207 drives the unpacking lifting tray guide rail 205 to lift the unpacking lifting tray 202, the unpacking in-position photoelectric 219 detects the box, the unpacking clamping cylinder 208 drives the unpacking clamping grabbing bar 212 to clamp the box, the unpacking lifting cylinder 207 descends to lower the unpacking lifting tray 202 to the bottom, the unpacking storage cylinder 213 drives the unpacking storage loading bar 217 to extend, the unpacking clamping cylinder 208 drives the unpacking clamping grabbing bar 212 to withdraw, and the box is lowered onto the unpacking storage loading bar 217 for the operator to pick up the operation;

[0113] S3: The box body is returned from the empty storage area 4 to the stacking and sorting area 3;

[0114] After the picking operation is completed, the completion button is triggered, and the empty box recovery cylinder 406 drives the empty return recovery guide rail 408 to retract the box placed on the unpacking storage load bar 217 to the empty return area load bar 404, and the stacking telescopic cylinder 305 drives the stacking telescopic grab bar 309 to extend and clamp the box; the stacking lifting cylinder 302 rises upward, driving all the originals and empty boxes on the stacking telescopic cylinder fixing plate 304 to rise together, and when the next empty box enters, the stacking lifting cylinder 302 drops downward, and at the same time, the stacking telescopic cylinder 305 drives the stacking telescopic grab bar 309 to withdraw, releasing the empty boxes and stacking them together;

[0115] When the second stacking detection photoelectric 311 detects the box body, the empty box secondary recovery cylinder 407 drives the empty return secondary recovery guide rail 409 to recover the stacked empty boxes stored on the empty return area cargo flow strip 404 to the first empty box in-position photoelectric 414, thereby realizing the automatic unpacking and separation of full box stacked parts and the automatic stacking and sorting of used empty boxes.

[0116] Running process:

[0117] The logistics personnel drive a tractor to deliver a chain of full-box parts to the production line side, and place the full-box stacked parts on the input area loading and unloading strip 104 in the input storage area 1. After the first full-box in-place photoelectric 114 in the input storage area 1 detects the position of the box, the full-box push cylinder 107 is controlled to move forward and backward, thereby driving the input push reversal block 113 to push the box to the second full-box in-place photoelectric 115 position. After the box is detected, the full-box secondary push cylinder 106 is controlled to move forward and backward, thereby driving the input secondary push reversal block 112 to continue to push the box forward to the full-box supply photoelectric 221 position and then reset, thereby starting the pushing work again to push the box to the full-box in-place photoelectric 222 in the unpacking and separation area 2;

[0118] When the unpacking lifting tray 202 is at the bottom, the unpacking lifting tray in-position switch 223 is triggered, and the full box in-position photoelectric 222 detects that the box is in position, and the unpacking lifting tray 202 is lifted by the unpacking lifting cylinder 207. After the unpacking in-position photoelectric 219 detects the box, the unpacking clamping cylinder 208 retracts, and the unpacking clamping grabbing strip 212 connected thereto extends relatively to clamp the box, and the unpacking lifting cylinder 207 descends to lower the unpacking lifting tray 202 to the bottom, the unpacking storage cylinder 213 retracts, and the unpacking storage loading strip 217 connected thereto extends relatively, and the unpacking clamping cylinder 208 extends, and the unpacking clamping grabbing strip 212 connected thereto withdraws toward each other, and the box is lowered onto the unpacking storage loading strip 217 for the operator to take and operate;

[0119] After the operation is completed, the completion button is triggered, and the empty box recovery cylinder 406 moves forward, thereby driving the return empty recovery counterflow block 412 to retract the box placed on the unpacking storage load bar 217 to the return empty area load flow strip 404, and the stacking telescopic cylinder 305 is retracted, and the stacking telescopic grabbing strip 309 connected thereto is extended relative to clamp the box, and the stacking lifting cylinder 302 is raised upward, driving all the originals and empty boxes on the stacking telescopic cylinder fixing plate 304 to rise together, and when the next empty box enters, the stacking lifting cylinder 302 drops downward, and at the same time, the stacking telescopic cylinder 305 is extended, and the stacking telescopic grabbing strip 309 connected thereto is withdrawn toward each other, and the empty boxes are released and stacked together;

[0120] When the second stacking detection photoelectric 311 detects the box body, the empty box secondary recovery cylinder 407 starts to move forward, thereby driving the empty secondary recovery reflux block 413 to recover the stacked empty boxes stored on the empty area carrier flow strip 404 to the first empty box in-place photoelectric 414 position. In this way, the functions of automatic unpacking and separation of full box stacked parts and automatic stacking and sorting of used empty boxes are realized, thereby eliminating manual work.

[0121] After applying the device and method of the present invention, the specific data and improved efficiency are as follows:

[0122] (1) Safety: 144*2 = 288 times of bending down are eliminated every day, which reduces labor intensity, completely eliminates manual box return, and realizes automation. OSHMS is reduced from Bb level to outside the scope, effectively preventing occupational diseases and taking precautions before they occur.

[0123] (2) Quality: Operators eliminate the time required to return empty containers and use this time to increase project quality confirmation, thus ensuring that the project is completed.

[0124] (3) Production: The box return method was changed from manual to automatic, completely eliminating 144 box returns per day and eliminating the need for operators to carry component boxes every day (372 units * 2 values ​​* 6 kg = 4464 kg). This completely solved the problem of empty box overflow caused by limited space, and operators no longer had to go up and down the platform to empty the boxes.

[0125] (4) Working hours: decreasing working hours (400 units * 2 values ​​* 8 seconds * 22 days / 3600 seconds = 39.69 hours / month)

[0126] (5) Others: Eliminate forced work and effectively improve the mobility rate, increasing the mobility rate of the project from 94.5% to 95.8%. The device is very easy to operate, which is conducive to the implementation of standard operations and the response of new employees.

[0127] (6) Cost reduction: Self-improvement saves costs, saving 63,000 yuan compared to purchasing this type of parts shed from outside.

[0128] In summary, the automatic unpacking and stacking mechanism developed and manufactured by the present invention can eliminate motion waste, eliminate additional operation time for returning boxes, and reduce labor intensity, thereby achieving the goal of helping to improve productivity.
