Description

[0002] In the modern manufacturing industry, the output of painted parts is increasing, and shortening the time from painting to entering the next process has become a strong competitive advantage for enterprises. Traditionally, painted parts are mostly dried by natural drying and heating. Natural drying relies on the air flow, temperature and humidity in the natural environment to evaporate the solvent on the surface of the painted parts, and the paint surface gradually dries and solidifies; heating drying uses a heating device to heat the air, and the hot air blows over the surface of the painted parts to accelerate the volatilization of the solvent, thereby increasing the drying speed.

[0003] However, natural drying is greatly affected by natural environmental factors. In the case of high humidity, low temperature or poor air circulation, the drying time will be significantly extended. Heating and drying is faster than natural drying, but it is not suitable for changing the properties of components under the influence of heating, and it is also prone to danger in the pyrotechnic industry.

[0031] The outbound drive unit 6 is connected to the rack unit 1, and is used to drive the full-box turnover box 100 received from the temporary storage roller line 3 to descend, and drive the full-box turnover box 100 to be transferred to the docking unit 7, and the docking unit 7 is used to transfer the full-box turnover box 100 to the flipping unit 8, so that the flipping unit 8 can transfer the dried painted parts in the full-box turnover box 100 to the equipment silo.

[0032] The outbound drive unit 6 provided in the embodiment of the present invention can transfer the turnover box 100 after drying to the flip unit 8 through the docking unit 7, and then the flip unit 8 pours the dried painted parts inside the turnover box 100 into the equipment silo for use in the next production process. In specific implementation, the embodiment of the present invention can provide that a turnover box outlet 112 is provided on the side of the shell 11, and the docking unit 7 is arranged opposite to the turnover box outlet 112; the outbound drive unit 6 includes an output roller assembly 61 and a second lifting drive assembly 62; the output roller assembly 61 includes an output roller 611 and an output motor 612, and the second lifting drive assembly 62 includes a second lifting guide rail 621, a second sprocket assembly 622 and a lifting drive motor; the second lifting drive assembly 62 is used to drive the output roller assembly 61 to rise and fall, so as to receive the turnover box 100 in the full box state transmitted by the temporary storage roller line 3 and drive the turnover box 100 in the full box state to rise and fall to the corresponding position of the flip conveyor line of the flip unit 8, and the output motor 612 is used to drive the output roller 611 to rotate so that the turnover box 100 in the full box state is transferred to the docking unit 7, so that the docking unit 7 transfers the turnover box 100 in the full box state to the upper part of the flip conveyor line.

[0035] The paint parts circulation ventilation and drying system provided by the embodiment of the present invention utilizes the boxing cache unit 9 to seamlessly connect with the coating production line to ensure the continuous production of the production line. At the same time, a large number of paint parts turnover boxes 100 are stored through the multi-layer temporary storage roller line 3. In addition, the three-dimensional warehouse outlet formed by the rack unit 1 is designed with a docking unit 7, so that the paint parts turnover box 100 can be automatically shipped out of the warehouse and the paint parts can be poured into the designated position of the next process, realizing the automatic transmission, drying and discharge of the paint parts.

[0036] The air intake fan, exhaust port, and temperature and humidity sensor are installed inside the three-dimensional warehouse to speed up the air flow inside the three-dimensional warehouse while monitoring the temperature and humidity changes inside the three-dimensional warehouse to avoid unnecessary dangers caused by excessive temperature when the painted parts are pyrotechnics. The design of the above circulation system can not only solve the low drying efficiency under natural wind, but also solve the dangers of drying and heating in the pyrotechnics industry, and can also realize large-scale continuous and uninterrupted production of painted parts.

[0037] The connection relationship and usage method of the various components of the system provided by the embodiment of the present invention are described in detail below.

[0038] An embodiment of the present invention provides a circulating ventilation and drying system for painted parts, which includes: a rack unit 1, a return roller line 2, a multi-layer temporary storage roller line 3, an air intake unit 4, a storage drive unit 5, a storage drive unit 6, a docking unit 7, a flipping unit 8, and a packing cache unit 9.

[0039] The connection relationship is as follows: the multi-layer temporary storage roller line 3 and the return roller line 2 are respectively fixed on the frame unit 1 through the roller connecting plate 32, the storage drive unit 5 and the outbound drive unit 6 are respectively fixed on the material input and output positions on both sides of the roller line, the packing cache unit 9 is installed at the painting component entrance 111 of the frame unit 1, and the flip unit 8 is placed next to the frame unit 1 after the docking unit 7 in the outbound drive unit 6 corresponds accurately.

[0040] The air intake unit 4 is arranged on the housing of the rack unit, and includes an air intake fan 41 and an exhaust port 42. The air intake fan 41 can accelerate the air flow in the housing, and finally exhaust the air through the exhaust port 42. In actual application, the number of air intake fans 41 and the number of exhaust ports 42 can be increased or decreased according to actual needs.

[0041] The cache bin 91 in the packing cache unit 9 is directly installed at the paint component entrance 111 of the rack unit 1, and is seamlessly connected to the front-end painting production line. When the turnover box 100 is in the gap between full and empty, the cache switch cylinder 93 opens to close the cache hopper, and the painted components flowing into the front-end production line are cached in the cache bin 91 to ensure continuous production of the production line.

[0042] The storage capacity of the multi-layer temporary storage roller line 3 can be adjusted according to the drying quantity and drying time required by the painting component process, and large-scale continuous production and rapid drying can be achieved by adding or subtracting the number of turnover boxes 100.

[0043] The outbound drive unit 6 is designed with a docking unit 7. After the painted parts turnover box 100 moves to the outbound position, it is lifted up by the lifting cylinder 75 and separated from the output roller 611. Under the joint rotation of the docking drive motor 73 and the output motor 612, the turnover box 100 automatically completes the outbound delivery and pours the painted parts into the designated position of the next process through the flipping unit 8, thereby realizing automatic discharging of the painted parts and ensuring continuous production of the production line.

[0044] When the system is in use, during the continuous discharging process of the coating production line at the front end of the painted parts entrance 111, the empty turnover box 100 is placed below the buffer hopper. After the empty turnover box 100 receives a certain number of painted parts and the turnover box 100 is full, it rises to the designated position of the multi-layer temporary storage roller line 3 under the action of the first lifting drive assembly 52 in the warehousing drive unit 5, and the warehousing motor 512 drives the roller to transport the full turnover box 100 into the multi-layer temporary storage roller line 3. After the turnover box 100 detaches from the input roller 511, the first lifting drive assembly 52 lifts the input roller 511 to the front end of the return roller line 2 to receive the empty turnover box 100. During the alternation of the turnover box 100, the cache switch cylinder 93 is opened, and the cache hopper 92 is closed. The painted parts flowing in from the front production line are cached in the cache bin 91. After the full box and the empty box are alternated, they return to the position below the cache hopper 92. The cache switch cylinder 93 is closed, and the cache hopper 92 is opened. The painted parts in the front cache continue to flow into the empty turnover box 100 to realize automatic circulation.

[0045] During storage, when the first lifting drive assembly 52 of the storage drive unit 5 lifts the turnover box 100 to the end of the corresponding temporary storage roller line 3, the temporary storage roller 31 rotates and transports the full turnover box 100 to the designated position. After the double-position detection switch 34 detects the turnover box 100, the blocking cylinder 33 acts to block the turnover box 100 to stop the turnover box from running, and the temporary storage roller 31 stops rotating (another detection switch detects whether the box is still moving, adding one more detection to achieve the purpose of protecting the box), until the temporary storage roller line 3 temporarily stores the specified number of boxes, and then the turnover box 100 enters the next layer of temporary storage roller line 3. The multi-layer temporary storage roller line 3 is designed to temporarily store N boxes. When the N+1 box is full, it is temporarily stored on the storage drive unit 5. Finally, the temporary storage of N+1 boxes is completed.

[0046] When out of the warehouse, the outbound drive unit 6 is lifted to the front end of the temporary storage roller line 3 where the turnover box 100 needs to be out of the warehouse through the second lifting drive assembly 62. The temporary storage roller 31 rotates to transport the turnover box 100 to the output roller 611 of the outbound drive unit 6. The second lifting drive assembly 62 lifts the turnover box 100 to the corresponding position of the flip roller line 82. The lifting cylinder 75 lifts the turnover box 100 to separate from the output roller 611. Under the joint rotation of the docking drive motor 73 and the output motor 612, the turnover box 100 is transported from the docking belt assembly 72 to the top of the flip roller line 82. The lifting cylinder 75 is closed to make the turnover box 100 fall onto the flip roller line 82 to complete the outbound delivery.

[0047] After the turnover box 100 falls onto the flipping roller line 82, the flipping roller line 82 rotates to transfer the turnover box 100 to the tipping assembly 83, the clamping cylinder 84 opens to clamp the turnover box 100 to a limit position, and then the flipping motor 85 drives the tipping assembly 83 to rotate, pouring the painted parts in the turnover box 100 into the silo of the rear-end equipment, realizing automatic discharging of the painted parts and ensuring continuous production of the production line.

[0048] It can be understood that the system provided by the embodiment of the present invention is suitable for the front-end equipment with continuous discharge mode. During the packing process, a packing cache unit 9 is designed when two boxes are alternated. It is mainly used to cache the painted parts while the warehousing drive unit 5 transfers the next box to its place after the previous box is full, so as to ensure the continuous production of the production line.

[0049] The storage capacity of the multi-layer temporary storage roller line 3 can be adjusted according to the drying quantity and drying time required by the painting component process, and large-scale continuous production and rapid drying can be achieved by adding or subtracting the number of turnover boxes 100.

[0050] The docking unit 7 designed for outbound delivery can automatically transfer the dried turnover box 100 to the overturning component 83, and automatically transfer the painted parts to the back-end automation equipment. It can also be increased to two drying systems to share one overturning unit 8 according to the requirements of the front-end production line, which greatly saves costs and improves production efficiency.

[0051] In summary, the circulating ventilation and drying system for painted parts provided by the present invention utilizes a packing cache unit to seamlessly connect with the coating production line to ensure continuous production of the production line. Large-scale drying can be achieved by storing a large number of paint parts turnover boxes through a multi-layer temporary storage roller line. The docking unit is designed at the exit of the three-dimensional warehouse, so that the paint parts turnover boxes can automatically complete the outbound delivery and pour the painted parts into the designated position of the next process, so as to realize the automatic discharge of the painted parts and the docking with the back-end equipment. The drying of painted parts can realize automated production on production lines with increasingly higher degrees of automation. The system can be seamlessly connected with the coating production line to realize the automatic transmission, drying and discharge of painted parts, and improve the level of automation in production. It can not only solve the low drying efficiency under natural wind, but also solve the dangers of drying and heating in the pyrotechnics industry, and can also realize large-scale continuous and uninterrupted production of painted parts.
